EXHIBIT 3.B.1 FIFTH AMENDMENT TO THE SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF GULFTERRA ENERGY PARTNERS, L.P. This Fifth Amendment (this "AMENDMENT") dated August 22, 2003 (the "AMENDMENT DATE"), to the Second Amended and Restated Agreement of Limited Partnership of GulfTerra Energy Partners, L.P. (the "PARTNERSHIP"), amended and restated effective as of July 23, 2003 (as amended, the "PARTNERSHIP AGREEMENT"), is entered into by and among GulfTerra Energy Company, L.L.C., a Delaware limited liability company, as the General Partner (the "GENERAL PARTNER"), and the Limited Partners. INTRODUCTION The Partnership desires to amend certain terms of the Series F Convertible Units as set forth in the Statement of Rights, Privileges and Limitations of Series F Convertible Units (the "STATEMENT") of the Partnership attached as Annex A to the Third Amendment to the Partnership Agreement. AGREEMENT In consideration of the covenants, conditions and agreements contained herein, pursuant to Section 15.1 of the Partnership Agreement, the Partnership Agreement is hereby amended as set forth herein. 1. UNDEFINED TERMS. Undefined terms used herein are defined in the Partnership Agreement. 2. AMENDMENTS. The Partnership Agreement is hereby amended by amending the Statement as follows: A. The following (1) Sections 1.13, 1.14 and 1.15 shall be inserted into the Statement following Section 1.12 and existing Section 1.54 of the Statement, (2) Section 1.24 shall be inserted into the Statement following Section 1.20 (which has been renumbered as Section 1.23 pursuant to this Section 2.A) and (3) Section 1.59 shall be inserted into the Statement following Section 1.54 (which has been renumbered as Section 1.58 pursuant to this Section 2.A), and (X) the existing Sections 1.13 through 1.20 of the Statement shall be renumbered 1.16 through 1.23, respectively, (Y) the existing Sections 1.21 through 1.54 of the Statement shall be renumbered 1.25 through 1.58, respectively, and (Z) the existing Sections 1.55 through 1.61 of the Statement shall be renumbered 1.60 through 1.66, respectively: "1.13 CASHLESS CONVERSION is defined in Section 2.2(b)."

"1.14 CASHLESS CONVERSION TRIGGER PRICE means $26.00, subject to adjustment pursuant to Section 3." "1.15 CASHLESS SETTLEMENT is defined in Section 2.2(a)." "1.24 DEEMED CONVERSION means any conversion of Series F Convertible Units pursuant to which the Partnership does not receive any cash or Partnership Bonds, specifically any conversion (i) in connection with a Cashless Settlement or a Cashless Conversion, (ii) under Section 2.5(d), (iii) pursuant to which the Holder actually receives Acquisition Consideration in the form of cash net of the relevant Conversion Consideration, or (iv) under Sections 3.3(c), 3.3(d) and 3.3(f)." "1.58 SETTLEMENT UNITS is defined in Section 2.2(a)." B. The definition of "Conversion Consideration" set forth in Section 1.16 of the Statement (which has been renumbered as Section 1.19 pursuant to Section 2.A hereof) is hereby amended by adding the following sentence at the end thereof: "For a Deemed Conversion, the Conversion Consideration shall be such amount designated in the relevant Conversion Notice, notwithstanding that no payment is made, or required to be made, to the Partnership in connection with such conversion." C. The definition of "Minimum Conversion Price" set forth in Section 1.28 of the Statement (which has been renumbered as Section 1.31 pursuant to Section 2.A hereof) is hereby amended by adding "or Settlement Units" after "Cash Settlement Amount." D. The definition of "Series F2 Vesting Amount" set forth in Section 1.54 of the Statement (which has been renumbered as Section 1.57 pursuant to Section 2.A hereof) is hereby amended by (1) adding "or Settlement Units" at the end of clause (ii) thereof and by (2) inserting the following as clause (iv) and renumbering the existing clause (iv) as clause (v): "(iv) designated in any Conversion Notice delivered in connection with a Cashless Conversion, and" E. The proviso in Section 2.1(a) of the Statement is hereby amended in its entirety to read as follows: "; provided that the aggregate Conversion Consideration that the Partnership receives (or is deemed to have received in connection with Deemed Conversions) pursuant to conversions of any Series F1 Convertible Unit (the "SERIES F1 CONVERSION CONSIDERATION"), shall not exceed $1,000,000." 2

F. The proviso in Section 2.1(b) of the Statement is hereby amended in its entirety to read as follows: "; provided that the aggregate Conversion Consideration that the Partnership receives (or is deemed to have received in connection with Deemed Conversions) pursuant to conversions of any Series F2 Convertible Unit (the "SERIES F1 CONVERSION CONSIDERATION"), shall not exceed $500,000." G. Section 2.2 of the Statement is hereby amended in its entirety to read as follows: "2.2 CASHLESS SETTLEMENT; CASHLESS CONVERSION. (a) CASHLESS SETTLEMENT. If the Conversion Unit Price with respect to any Conversion Notice is below the Minimum Conversion Price, then the Partnership shall, in lieu of issuing Series A Common Units upon conversion of Series F Convertible Units covered by such Conversion Notice, take one of the following actions (provided, that the election between clauses (i) and (ii) below shall be in the Partnership's sole discretion): (i) pay an amount in cash to such Holder equal to the difference of (x) the product of (A) the number of Series A Common Units issuable on the relevant Conversion Closing Date and (B) the Daily Market Unit Price as of the Business Day immediately preceding the Conversion Notice Date and (y) the Conversion Consideration designated in the relevant Conversion Notice (the "CASH SETTLEMENT AMOUNT"), or (ii) issue to such Holder a number of Series A Common Units equal to the Cash Settlement Amount divided by the Prevailing Unit Price (the "SETTLEMENT UNITS"); provided, that the Holder shall not be required to tender the Conversion Consideration designated in the relevant Conversion Notice (a "CASHLESS SETTLEMENT"). At any time and from time to time with twenty (20) Business Days notice to the Holder, the Partnership shall be entitled to establish a new Minimum Conversion Price. (b) CASHLESS CONVERSION ELECTION. If the Prevailing Unit Price is below the Cashless Conversion Trigger Price, a converting Holder may elect in the Conversion Notice to receive Settlement Units, in lieu of the number of Series A Common Units otherwise issuable upon conversion of the Series F Convertible Units covered by such Conversion Notice, provided, that the Holder shall not be required to tender the Conversion Consideration designated in the relevant Conversion Notice (a "CASHLESS CONVERSION"). Notwithstanding the Holder's election to receive Settlement Units in a Cashless Conversion, the Partnership shall have the sole right to elect no later than the Business Day immediately after 3

the date such Conversion Notice is delivered to the Partnership to consummate such Cashless Conversion with the payment of the Cash Settlement Amount in lieu of the issuance of Settlement Units. In addition, if the Prevailing Unit Price is below the Cashless Conversion Trigger Price and the converting Holder does not elect Cashless Conversion in a Conversion Notice, then the Partnership may, no later than the one Business Day immediately after the date such Conversion Notice is delivered to the Partnership, elect Cashless Conversion (and whether the settlement shall be in the form of the Cash Settlement Amount or the Settlement Units). (c) CLOSING OF CASHLESS SETTLEMENT OR CASHLESS CONVERSION. The Partnership shall close a Cashless Settlement or a Cashless Conversion on the relevant Conversion Closing Date. The Partnership shall (i) pay the Cash Settlement Amount, if applicable, in immediately available funds by 5:00 p.m., New York City time, on the relevant Conversion Closing Date, to the account specified in the Holder's Conversion Notice, or (ii) issue and deliver the Settlement Units, if applicable, pursuant to Section 2.8(a) on the relevant Conversion Closing Date. Upon receipt of the Cash Settlement Amount or the Settlement Units in connection with any Cashless Settlement or Cashless Conversion, that number of Series F Convertible Units with aggregate Series F1 Conversion Consideration and Series F2 Conversion Consideration equal to the Conversion Consideration designated in the Conversion Notice shall be deemed converted. If the Conversion Consideration deemed to have been tendered pursuant to Section 2.2(a) or 2.2(b) is less than the remaining, unconverted portion of Series F Convertible Units represented by the certificate(s) tendered to the Partnership on the Conversion Closing Date, the Partnership shall issue a replacement certificate(s) as provided in Section 2.8(b). (d) CASHLESS CONVERSIONS INITIATED BY HOLDER. In computing the Cash Settlement Amount or the Settlement Units on a Cashless Conversion initiated by a Holder, in no event shall such computation be based on a number of Series A Common Units in excess of the Maximum Number. Further, in determining whether the Maximum Number has been reached, computation shall be made based on the number of Series A Common Units, if any, actually issued in the case of a Cashless Settlement or a Cashless Conversion, provided, that if a Cashless Conversion is initiated by a Holder, then such computation shall be based on the number of Series A Common Units that would have been issued on the relevant Conversion Closing Date without giving effect to such Cashless Conversion and without regard to whether such Cashless Conversion was settled with Settlement Units, all subject to adjustment by Section 3. Notwithstanding the foregoing, nothing in this Section 2.2(d) shall be construed to change the meaning or the intent of the Statement as originally filed as Annex A to the Partnership Agreement with respect to any provision other than as such may relate to Cashless Conversion or, in the case of Cashless Settlement, as specifically provided in this Section 2.2(d). 4

(e) The Partnership shall, within two (2) Business Days of a Conversion Closing Date pursuant to this Section 2.2, give the Holder written notice if the Partnership is unable to tender the Cash Settlement Amount on such Conversion Closing Date. Within one (1) Business Day after receipt of such notice, Holder shall give the Partnership written notice, at its sole election, of its election to (x) withdraw the Conversion Notice or (y) receive Series A Common Units as determined pursuant to Section 3.1 in lieu of the Cash Settlement Amount, which Conversion Closing Date shall occur within three (3) Business Days of the Partnership's receipt of such Holder's election pursuant to this Section 2.2(e)." H. Section 2.6 of the Statement is hereby amended by adding "(or deemed to have been received in connection with Deemed Conversions)" after "Conversion Consideration." I. The introductory language of Section 2.7 of the Statement is hereby amended by adding ", except with respect to Deemed Conversions," immediately preceding "shall deliver payment." J. The second sentence of Section 2.7 of the Statement is hereby amended by adding "or, in the case of Deemed Conversions, upon delivery of the certificate(s) representing the Series F Convertible Unit(s)" after "Upon the Partnership's receipt of the Conversion Consideration." K. Section 2.8(b) of the Statement is hereby amended by replacing "Sections 2.2, 2.5(d), 3.3(d) and 3.3(f)" with Deemed Conversions in both places in which such reference appears in Section 2.8(b) of the Statement. L. Section 3.1 of the Statement is hereby amended by adding the following sentence at the end thereof: "Notwithstanding the foregoing, upon a Cashless Settlement or a Cashless Conversion, the number of Series A Common Units which a Holder shall be entitled to receive upon conversion of Series F Convertible Units shall be as set forth in Section 2.2(a) or 2.2(b), respectively, subject to the adjustments, terms and conditions in this Statement." M. Section 3.2 of the Statement is hereby amended by adding ", the Cashless Conversion Trigger Price" after "the Prevailing Unit Price." N. Section 3.3(d) of the Statement is hereby amended by adding ", Cashless Conversion Trigger Price" after "the Prevailing Unit Price." O. Section 3.3(e) of the Statement is hereby amended by adding ", Cashless Conversion Trigger Price" after "the Prevailing Unit Price." 5

P. The first paragraph of Exhibit B to this Statement is hereby amended in its entirety to read as follows: "Pursuant to the terms and conditions contained in the Statement, [HOLDER] hereby elects to convert $[__________](1) of Series F(2) Convertible Units into [ ] Series A Common Units, which would be purchased at a Conversion Unit Price of $[____] [, AND SHALL DELIVER ON THE CONVERSION CLOSING DATE SUCH AMOUNT VIA WIRE TRANSFER OF IMMEDIATELY AVAILABLE FUNDS AS PAYMENT FOR SUCH SERIES A COMMON UNITS] [, AND SHALL DELIVER ON THE CONVERSION CLOSING DATE THAT NUMBER OF PARTNERSHIP BONDS WITH AN AGGREGATE PRINCIPAL AMOUNT PLUS ACCRUED INTEREST EQUAL TO SUCH DOLLAR AMOUNT AS PAYMENT FOR SUCH SERIES A COMMON UNITS] [PURSUANT TO A [CASHLESS SETTLEMENT][CASHLESS CONVERSION]] in accordance with the terms of the Statement. All undefined capitalized terms used in this Conversion Notice shall have the meaning set forth in the Statement." N. Except as expressly set forth herein, the Partnership Agreement and Statement shall remain in full force and effect. 3. MISCELLANEOUS. A. CONSTRUCTION. Sections 10 and 11 of the Statement shall govern this Amendment. B. FURTHER ACTION. The parties hereto shall execute and deliver all documents, provide all information and take or refrain from taking action as may be necessary or appropriate to achieve the purposes of this Amendment. C. BINDING EFFECT. This Amendment shall be binding upon and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. D. INTEGRATION. This Amendment constitutes the entire agreement among the parties hereto pertaining to the subject matter hereof and supersedes all prior agreements and understandings pertaining thereto. E. CREDITORS. None of the provisions of this Amendment shall be for the benefit of, or shall be enforceable by, any creditor of the Partnership. F. WAIVER. No failure by any party to insist upon the strict performance of any covenant duty, agreement or condition of this Amendment or to - ---------- (1) Insert the dollar amount of Series F Convertible Units being converted. In the case of partial conversion, a new certificate representing the Series F Convertible Unit shall be issued and delivered, representing the unconverted portion of the Series F Convertible Unit. (2) Indicate whether Series F1 or Series F2 is being tendered. 6

exercise any right or remedy consequent upon a breach thereof shall constitute a waiver of any such breach or any other covenant duty, agreement or condition. G. COUNTERPARTS. This Amendment may be executed in counterparts, all of which together shall constitute an agreement binding on all of the parties hereto, notwithstanding that all such parties are not signatories to the original or the same counterpart. Each party shall become bound by this Amendment immediately upon affixing its signature hereto, or, in the case of a Person acquiring a Unit, upon executing and delivering a Transfer Application as described in the Partnership Agreement, independently of the signature of any other party. H. APPLICABLE LAW. This Amendment shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of law. I. INVALIDITY OF PROVISIONS. If any provision of this Amendment is or becomes invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not be affected thereby.

(b) For purposes of computing the amount of any item of income, gain, loss or deduction to be reflected in the Partners' Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including, without limitation, any method of depreciation, cost recovery or amortization used for that purpose), provided, that: (i) Solely for purposes of this Section 4.6, the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the Charter Documents) of (x) all property owned by the non-corporate Operating Companies and Joint Ventures and (y) the fair market value of the stock of the corporate Operating Companies and Joint Ventures. (ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 5.1. (iii) Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code which may be made by the Partnership and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. (iv) Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership's Carrying Value with respect to such property as of such date. (v) In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 4.6(d) to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined (A) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment and (B) using a rate of depreciation cost recovery or amortization derived from the same method and useful life (or, if applicable, the remaining useful life) as is applied for federal income tax purposes; provided, however, that if the asset has a zero adjusted basis for federal income tax purposes, depreciation, cost recovery or amortization deductions shall be determined using any reasonable method that the General Partner may adopt. 26

(vi) If the Partnership's adjusted basis in depreciable or cost recovery property is reduced for federal income tax purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction shall, solely for purposes hereof, be deemed to be an additional depreciation or cost recovery deduction in the year such property is placed in service and shall be allocated among the Partners pursuant to Section 5.1. Any restoration of such basis pursuant to Section 48(q)(2) of the Code shall, to the extent possible, be allocated in the year of such restoration as an item of income pursuant to Section 5.1. (c) A transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred; provided, however, that if the transfer causes a termination of the Partnership under Section 708(b)(1)(B) of the Code, the Partnership's properties shall be deemed to have been distributed in liquidation of the Partnership to the Partners (including any transferee of a Partnership Interest that is a party to the transfer causing such termination) pursuant to Sections 14.3 and 14.4 and recontributed by such Partners in reconstitution of the Partnership. Any such deemed distribution shall be treated as an actual distribution for purposes of this Section 4.6. In such event the Carrying Values of the Partnership properties shall be adjusted immediately prior to such deemed distribution pursuant to Section 4.6(d)(ii) and such Carrying Values shall then constitute the Agreed Values of such properties upon such deemed contribution to the reconstituted Partnership. The Capital Accounts of such reconstituted Partnership shall be maintained in accordance with the principles of this Section 4.6. (d) (i) Consistent with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Units for cash or Contributed Property or the conversion of the General Partner's Partnership Interest to Units pursuant to Section 13.3(b), the Capital Accounts of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property immediately prior to such issuance and had been allocated to the Partners at such time pursuant to Section 5.1. (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of each Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated to the Partners, at such time, pursuant to Section 5.1. 4.7 Interest. No interest shall be paid by the Partnership on Capital Contributions or on balances in Partners' Capital Accounts. 27

4.8 No Withdrawal. No Partner shall be entitled to withdraw any part of its Capital Contributions or its Capital Account or to receive any distribution from the Partnership, except as provided in this Agreement. 4.9 Loans from Partners. Loans by a Partner to the Partnership shall not constitute Capital Contributions. If any Partner shall advance funds to the Partnership in excess of the amounts required hereunder to be contributed by it to the capital of the Partnership, the making of such excess advances shall not result in any increase in the amount of the Capital Account of such Partner. The amount of any such excess advances shall be a debt obligation of the Partnership to such Partner and shall be payable or collectible only out of the Partnership Assets in accordance with the terms and conditions upon which such advances are made. 4.10 No Fractional Units. No fractional Units shall be issued by the Partnership. 4.11 Partnership Interest Adjusting Events. (a) Subject to Section 4.11(d), the General Partner may effect a Partnership Interest Adjusting Event, including a pro rata distribution of Units or other Partnership Securities to all Record Holders thereof or a subdivision or combination of Units or other Partnership Securities; provided, however, that subject to Section 4.11(d), after any such Partnership Interest Adjusting Event, each Partner shall have the same ownership interest in the Partnership as before such Partnership Interest Adjusting Event. (b) Whenever such a Partnership Interest Adjusting Event is declared, the General Partner shall select a Record Date for such Partnership Interest Adjusting Event at least 20 days prior to such Record Date. The Record Date shall be as of a date not less than 10 days prior to the date of the notice to the Record Holders of such Partnership Interest Adjusting Event. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Units to be held by each Record Holder after giving effect to such Partnership Interest Adjusting Event. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation. (c) Promptly following any such Partnership Interest Adjusting Event, the General Partner may cause Unit Certificates to be issued to the Record Holders of Units as of the applicable Record Date representing the new number of Units held by such Record Holders, or the General Partner may adopt such other procedures as it may deem appropriate to reflect such Partnership Interest Adjusting Event; provided, however, that if any such Partnership Interest Adjusting Event results in a smaller total number of Units Outstanding, the General Partner shall require, as a condition to the delivery to a Record Holder of such new Unit Certificate, the surrender of any Unit Certificate held by such Record Holder immediately prior to such Record Date. (d) The Partnership shall not issue fractional Units upon any Partnership Interest Adjusting Event. If a Partnership Interest Adjusting Event would result in the issuance of fractional Units but for the provision of Section 4.10 and this Section 4.11(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit). 28

As between the Limited Partners holding Series A Preference Units and the Limited Partners holding Series B Preference Units, any distributions under this Section 5.1(a)(iv) shall be allocated based on the Preference Unit Sharing Ratios, and as among the Limited Partners holding a particular series of Preference Units, such distributions shall be allocated in the proportion that the respective number of Preference Units in such series held by them bears to the total number of Preference Units in such series then Outstanding; and (b) Net Losses. After giving effect to the special allocations set forth in Sections 5.1(d) and 5.1(e), all remaining items of income, gain, loss and deduction taken into account in computing Net Losses for such taxable period shall be allocated in the same manner as such Net Losses are allocated hereunder, which Net Losses shall be allocated as follows: (i) While any Series A Preference Units are Outstanding. During any period in which any Series A Preference Units are outstanding: (A) First, 1% to the General Partner and 99% to the Limited Partners holding Series A Common Units, Series A Preference Units and Series B Preference Units (allocated between each such series and among the Limited Partners holding Units of each such series as provided below in this Section 5.1(b)(i)(A)) until Net Losses are allocated to each Unit pursuant to this Section 5.1(b)(i)(A) for the current taxable year and all previous taxable years in an amount equal to the Net Income allocated to such Unit pursuant to Section 5.1(a)(iv) for all previous taxable years. As among the Limited Partners holding each of the Series A Common Units, Series A Preference Units and Series B Preference Units, any distributions under this Section 5.1(b)(i)(A) shall be allocated in proportion to the Net Income allocated to one of each such Units pursuant to Section 5.1(a)(iv) for all previous taxable years, and as among the Limited Partners holding a particular series of Units, such distributions shall be allocated in the proportion that the respective number of Units in such series held by them bears to the total number of Units in such series then Outstanding; (B) Second, 1% to the General Partner and 99% to the Limited Partners holding Series A Common Units, in the proportion that the respective number of Series A Common Units held by them bears to the total number of Series A 30

Common Units then Outstanding, provided that Net Losses shall not be allocated pursuant to this Section 5.1(b)(ii) to the extent that such allocation would cause any Limited Partner to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account); (C) Third, 1% to the General Partner and 99% to the Limited Partners holding Series A Preference Units and Series B Preference Units (allocated between each such series and among the Limited Partners holding Units of each such series as provided below in this Section 5.1(b)(i)(C)), provided that Net Losses shall not be allocated pursuant to this Section 5.1(b)(i) to the extent that such allocation would cause any Limited Partner to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account). As among the Limited Partners holding the Series A Preference Units and the Limited Partners holding the Series B Preference Units, any distributions under this Section 5.1(b)(i)(C) shall be allocated based on their respective Preference Unit Sharing Ratios, and as among the Limited Partners holding a particular series of Units, such distributions shall be allocated in the proportion that the respective number of Units in such series held by them bears to the total number of Units in such series then Outstanding; and (D) Fourth, the balance, if any, 100% to the General Partner. (ii) While no Series A Preference Units are Outstanding. During any period in which no Series A Preference Units are outstanding: (A) First, 1% to the General Partner and 99% to the Limited Partners holding Series A Common Units and Series B Preference Units (allocated between each such series and among the Limited Partners holding Units of each such series as provided below in this Section 5.1(b)(ii)(A)) until Net Losses are allocated to each Unit pursuant to this Section 5.1(b)(ii)(A) for the current taxable year and all previous taxable years in an amount equal to the Net Income allocated to such Unit pursuant to Section 5.1(a)(iv) for all previous taxable years. As among the Limited Partners holding the Series A Common Units and the Limited Partners holding the Series B Preference Units, any distributions under this Section 5.1(b)(ii)(A) shall be allocated in proportion to the amounts of Net Income allocated to the Limited Partners holding such Units pursuant to Section 5.1(a)(iv) for all previous taxable years, and as among the Limited Partners holding a particular series of Units, such distributions shall be allocated in the proportion that the respective number of Units in such series held by them bears to the total number of Units in such series then Outstanding; (B) Second, 1% to the General Partner and 99% to the Limited Partners holding Series A Common Units, in the proportion that the respective number of Series A Common Units held by them bears to the total number of Series A Common Units then Outstanding, provided that Net Losses shall not be allocated 31

(c) Net Termination Gains and Losses. After giving effect to the allocations in Section 4.2 and the special allocations set forth in Sections 5.1(e) and 5.1(e), all items of income, gain, loss and deduction taken into account in computing Net Termination Gain or Net Termination Loss for such taxable period shall be allocated in the same manner as such Net Termination Gain or Net Termination Loss is allocated hereunder. All allocations under this Section 5.1(d) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 5.1 and after all distributions of Available Cash provided under Sections 5.4 and 5.5 have be made with respect to such taxable period. (i) If a Net Termination Gain is recognized, such Net Termination Gain shall be allocated between the General Partner and the Limited Partners in the following manner (and the Adjusted Capital Accounts of the Partners shall be increased by the amount so allocated in each of the following subclauses, in the order listed, before an allocation is made pursuant to the next succeeding subclause): (A) first, to each Partner having a deficit balance in its Adjusted Capital Account in the proportion that such deficit balance bears to the total deficit balances in the Adjusted Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Adjusted Capital Account; (B) second, 99% to the Limited Partners holding Series A Preference Units and Series B Preference Units (allocated between each such series and among the Limited Partners holding Preference Units of each such series as provided below in this Section 5.1(d)(i)(B)) and 1.0% to the General Partner until the Adjusted Capital Account in respect of each Series A Preference Unit and Series B Preference Unit then Outstanding is equal to, as applicable, (aa) the sum of the Unrecovered Capital in respect of such Series A Preference Unit plus any then Series A Preference Unit Cumulative Deficiency or (bb) the Series B Preference Unit Liquidation Value. As between the Limited Partners holding Series A Preference Units and the Limited Partners holding Series B Preference 32

Units, any allocation under this Section 5.1(d)(i)(B) shall be made based on the Preference Unit Sharing Ratios, and as among the Limited Partners holding a particular series of Preference Units, such distributions shall be allocated in the proportion that the respective number of Preference Units in such series held by them bears to the total number of Preference Units in such series then Outstanding; (C) third, 99% to Limited Partners holding Series A Common Units, in the proportion that the respective number of Series A Common Units held by them bears to the total number of Series A Common Units then Outstanding, and 1.0% to the General Partner until the Adjusted Capital Account in respect of each Series A Common Unit then Outstanding is equal to the Unrecovered Capital with respect to such Series A Common Unit; (D) fourth, (aa) if the Net Termination Gain is recognized prior to the termination of the Series A Preference Unit Preference Period, 99% to all Limited Partners holding Series A Preference Units and Series A Common Units, in the proportion that the respective number of such Units held by them bears to the total number of such Units then Outstanding, or (bb) if the Net Termination Gain is recognized following the termination of the Series A Preference Unit Preference Period, 99% to all Limited Partners holding Series A Common Units, in the proportion that the respective number of Series A Common Units held by them bears to the total number of Series A Common Units then Outstanding, and 1% to the General Partner, until there has been allocated an amount per Series A Common Unit equal to (yy) the excess of the First Target Distribution per Unit over the Minimum Quarterly Distribution for each quarter of the Partnership's existence, less (zz) the amount per Unit of any distributions in respect of such Series A Common Units (including any distributions in respect of such Series A Common Units prior to conversion of such Units from Series A Preference Units) pursuant to Sections 5.4 and 5.5; (E) fifth, (aa) if the Net Termination Gain is recognized prior to the termination of the Series A Preference Unit Preference Period, 85.87% to all Limited Partners holding Series A Preference Units and Series A Common Units, in the proportion that the respective number of such Units held by them bears to the total number of such Units then Outstanding, or (bb) if the Net Termination Gain is recognized following the termination of the Series A Preference Unit Preference Period, 85.87% to all Limited Partners holding Series A Common Units, in the proportion that the respective number of Series A Common Units held by them bears to the total number of Series A Common Units then Outstanding, and 14.13% to the General Partner, until there has been allocated an amount per relevant Unit equal to (yy) the excess of the Second Target Distribution per Unit over the First Target Distribution per Unit for each quarter of the Partnership's existence, less (zz) the amount per Unit of any distributions in respect of such Series A Common Units (including any distributions in respect of such Series A Common Units prior to conversion of such Units from Series A Preference Units) pursuant to Sections 5.4 and 5.5; 33

(ii) if a Net Termination Loss is recognized, such Net Termination Loss shall be allocated to the Partners in the following manner: (A) first, to all Partners in proportion to the positive balances in their Adjusted Capital Accounts (or, if subsequent to the Series A Preference Unit Preference Period, 100% to the Limited Partners holding Series A Preference Units and Series B Preference Units, in proportion to the positive balances in their Adjusted Capital Accounts) until the Adjusted Capital Accounts of holders of Series A Preference Units are reduced to the amount of their Unrecovered Capital plus any arrearages with respect thereto and the Adjusted Capital Accounts of holders of Series B Preference Units are reduced to their Series B Preference Unit Liquidation Value; (B) second, 1% to the General Partner and 99% to the Limited Partners holding Series A Common Units, in proportion to, and to the extent of, the positive balances in their Adjusted Capital Accounts until all such balances are reduced to zero; 34

(C) third, 100% to the Limited Partners holding Series A Preference Units and Series B Preference Units, in proportion to, and to the extent of, the positive balances in their Adjusted Capital Accounts until all such balances are reduced to zero; and (D) fourth, the balance, if any, 100% to the General Partner. (d) Special Allocations. Notwithstanding any other provisions of this Section 5.1 (other than Section 5.1(e)), the following special allocation shall be made for such taxable period: (i) Priority Allocations. (A) If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 14.3 or 14.4) to any Limited Partner during a taxable year is greater (on a per Unit basis) than the amount of cash or the Net Agreed Value of property distributed to the other Limited Partners (on a per Unit basis), then (1) each Limited Partner receiving such greater cash or property distribution shall be allocated gross income in an amount equal to the product of (x) the amount by which the distribution (on a per Unit basis) to such Limited Partner exceeds the distribution (on a per Unit basis) to the Limited Partners receiving the smallest distribution and (y) the number of Units owned by the Limited Partner receiving the greater distribution and (2) the General Partner shall be allocated gross income in an amount equal to one-ninety-ninth (1/99) of the sum of the amounts allocated in clause (1) above. (B) All or a portion of the remaining items of Partnership gross income or gain for the taxable period if any, shall be allocated 100% to the General Partner (or its assignee) until the aggregate amount of such items allocated to the General Partner (or its assignee) under this paragraph (d)(i)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions declared before the end of the current taxable period and made to the General Partner (or its assignee) from the Closing Date to a date 45 days after the end of the current taxable period. (ii) Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners 49.49% to the General Partner and 50.51% to all Limited Partners in the proportion that the respective number of Units held by them bears to the total number of Units then outstanding. (iii) Discretionary Allocation. (A) Notwithstanding any other provision of Section 5.1(a), (b) or (d), the Agreed Allocations shall be adjusted so that to the extent possible, the net amount of items of income, gain, loss and deduction allocated to the Partner pursuant to the Required Allocations and the Agreed Allocation, together, shall be equal to the net amount of such item that would have been allocated to each such Partner under the Agreed Allocations had there been no Required Allocations; provided, 35

however, that for purposes of applying this Section 5.1(e)(iii)(A), it shall be assumed that all chargebacks pursuant to Sections 5.1(e)(i) and (ii) have occurred. (B) The General Partner shall have reasonable discretion, with respect to each taxable year, to (1) apply the provisions of Section 5.1(e)(iii)(A) in whatever fashion as is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 5.1(e)(iii)(A) among the Partners in a manner that is likely to minimize such economic distortions. (e) Required Allocations. Notwithstanding any other provision of this Section 5.1, the following special allocations shall be made for such taxable period: (i) Partnership Minimum Gain Chargeback. Notwithstanding the other provisions of this Section 5.1, except as provided in Treasury Regulation Sections 1.704 2(f)(2) through (5), if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704 2(f)(6), 1.704 2(g)(2) and 1.704 2(j)(2)(i), or any successor provisions. For purposes of this Section 5.1(e), each Partner's Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 5.1 with respect to such taxable period (other than an allocation pursuant to Sections 5.1(e)(v) or 5.1(e)(vi)). (ii) Chargeback of Minimum Gain Attributable to Partner Nonrecourse Debt. Notwithstanding the other provisions of this Section 5.1 (other than 5.1(e)(i)), except as provided in Treasury Regulation Section 1.704 2(i)(4), if there is a net decrease in Minimum Gain Attributable to Partner Nonrecourse Debt during any Partnership taxable period any Partner with a share of Minimum Gain Attributable to Partner Nonrecourse Debt at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704 2(i)(4) and 1.704 2(j)(2)(ii), or any successor provisions. For purposes of this Section 5.1, such Partner's Adjusted Capital Account balance shall be determined and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 5.1(e), other than Section 5.1(e)(i) (and other than an allocation pursuant to Sections 5.1(e)(v) or 5.1(e)(vi)), with respect to such taxable period. (iii) Qualified Income Offset. In the event any Limited Partner unexpectedly receives adjustments, allocations or distributions described in Treasury Regulation Section 1.704 1(b)(2)(ii)(d)(4), 1.704 1(b)(2)(ii)(d)(5), or 1.704 1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specifically allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as 36

possible unless such deficit balance is otherwise eliminated pursuant to Section 5.1(e)(i) or 5.1(e)(ii). (iv) Gross Income Allocations. (A) In the event any Partner has a deficit balance in its Adjusted Capital Account at the end of any Partnership taxable period, such Partner shall be specifically allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 5.1(e)(iv)(A) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 5.1 have been tentatively made as if this Section 5.1(e)(iv)(A) was not in this Agreement. (B) If at the end of any Partnership taxable period, after all other allocations provided in this Section 5.1 have been tentatively made as if this Section 5.1(e)(iv)(B) was not in this Agreement, the total amount allocated in respect of any Series B Preference Unit under Section 5.1(a)(iv) during the period from the Series B Preference Unit Issuance Date through the date of such allocation is less than the total of all amounts distributed in respect of such Series B Preference Unit made during such period pursuant to Sections 5.5(a) and (b), then the Limited Partners holding Series B Preference Units shall be specifically allocated, as quickly as possible (but after the requirements of Section 5.1(e)(iv)(A) have been met), items of Partnership gross income and gain such that the total amount allocated in respect of any Series B Preference Unit under Section 5.1(a)(iv) during the period from the Series B Preference Unit Issuance Date through the date of such allocation is equal to the total of all amounts distributed in respect of such Series B Preference Unit during such period pursuant to Sections 5.5(a) and (b). (v) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners in the same manner as Net Income is allocated pursuant to Section 5.1(a)(iv). If the Managing General Partner determines in its good faith discretion that the Partnership's Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the Limited Partners, to revise the prescribed ratio to the numerically closest ratio which does satisfy such requirements. (vi) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss for such Partnership Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704 2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss. 37

5.2 Allocations for Tax Purposes. (a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction which is recognized by the Partnership for federal income tax purposes shall be allocated among the Partners in the same manner as its correlative item of "book," income, gain, loss or deduction is allocated pursuant to Section 5.1. (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners as follows: (i) (A) In the case of a Contributed Property, such items attributable thereto shall be allocated among the Partners in the manner provided under Section 704(c) of the Code that takes into account the variation between the Agreed Value of such property and its adjusted basis at the time of contribution; and (B) except as otherwise provided in Section 5.2(b)(iii), any item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Partners in the same manner as its correlative item of "book" gain or loss is allocated pursuant to Section 5.1. (ii) (A) In the case of an Adjusted Property, such items shall (1) first, be allocated among the Partners in a manner consistent with the principles of Section 704(c) of the Code to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Section 4.6(d)(i) or (ii), and (2) second, in the event such property was originally a Contributed Property, be allocated among the Partners in a manner consistent with Section 5.2(b)(i)(A); and (B) except as otherwise provided in Section 5.2(b)(iii), any item of Residual Gain or Residual Loss attributable to an Adjusted Property shall be allocated among the Partners in the same manner as its correlative item of "book" gain or loss is allocated pursuant to Section 5.1. (iii) Any items of income, gain, loss or deduction otherwise allocable under Section 5.2(b)(i)(B) or 5.2(b)(ii)(B) shall be subject to allocation by the General Partner in a manner designed to eliminate, to the maximum extent possible, Book-Tax Disparities in a Contributed Property or Adjusted Property otherwise resulting from the application of the "ceiling" limitation (under Section 704(c) of the Code or Section 704(c) principles) to the allocations provided under Section 5.2(b)(i)(A) or 5.2(b)(ii)(A). (c) For the proper administration of the Partnership or for the preservation of uniformity of the Units (or any class or classes thereof), the General Partner shall have sole discretion to (i) adopt such conventions as it deems appropriate in determining the amount of depreciation amortization and cost recovery deductions; (ii) make special allocations for federal income tax purposes of income (including, without limitation, gross income) or deductions; and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Units (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 5.2(c) only if such conventions, allocations or 38

amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Units issued and Outstanding of the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code. (d) The General Partner in its sole discretion may determine to depreciate the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation method and useful life applied to the Partnership's common basis of such property, despite the inconsistency of such approach with Proposed Treasury Regulation Section 1.168 2(n) and Treasury Regulation Section 1.167(c) 1(a)(6). If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt a depreciation convention under which all purchasers acquiring Units in the same month would receive depreciation, based upon the same applicable rate as if they had purchased a direct interest in the Partnership's property. If the General Partner chooses not to utilize such aggregate method the General Partner may use any other reasonable depreciation convention to preserve the uniformity of the intrinsic tax characteristics of any Units that would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Units. In addition, for purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) (i) to adopt a convention whereby the price paid by a transferee of Units will be deemed to be the lowest quoted trading price of the Units on any National Securities Exchange on which such Units are traded during the calendar month in which such transfer is deemed to occur pursuant to Section 5.2(g) without regard to the actual price paid by such transferee and (ii) to treat the amount of any Section 743(b) adjustment with respect to properties of the non-corporate Operating Companies and Joint Ventures as being equal to the Section 743(b) adjustment attributable to the partnership interest in such Operating Companies and Joint Ventures. (e) Any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 5.2 be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income. (f) All items of income, gain, loss, deduction and credit recognized by the Partnership for federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code which may be made by the Partnership; provided, however, that such allocations once made, shall be adjusted as necessary or appropriate to take into account those adjustments permitted or required by Sections 734 and 743 of the Code. (g) Each item of Partnership income, gain, loss and deduction attributable to a transferred Partnership Interest of the General Partner or to transferred Units shall, for federal income tax purposes, be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Partners as of the close of the New York Stock Exchange on the last day of the preceding month; provided, however, that (i) except as otherwise provided in clause (ii), such items for the period beginning on the Closing Date and ending on the last day of the month in 39

which the Closing Date occurs shall be allocated to Partners as of the close of the New York Stock Exchange on the last day of that it month or (ii) if the Underwriters' over-allotment option is exercised, such items for the period beginning on the Closing Date and ending on the last day of the month in which the Option Closing Date (as defined in the Underwriting Agreement) occurs shall be allocated to the Partners as of the close of the New York Stock Exchange on the last day of that month; and provided further, that gain or loss on a sale or other disposition of any assets of the Partnership other than in the ordinary course of business shall be allocated to the Partners as of the opening of the New York Stock Exchange on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation as it determines necessary to the extent permitted or required by Section 706 of the Code and the regulations or ruling promulgated thereunder. (h) Allocations that would otherwise be made to a Limited Partner under the provisions of this Article V shall instead be made to the beneficial owner of Units held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner in its sole discretion. 5.3 Requirement and Characterization of Distributions. Within 45 days following the end of each calendar quarter, an amount equal to 100% of Available Cash with respect to such quarter (or period) shall be distributed in accordance with this Article V by the Partnership to the Partners, as of the Record Date for such distribution selected by the General Partner in its reasonable discretion. The immediately preceding sentence shall not modify in any respect the provisions of Section 4.2 regulating the distribution of any interest or other profit on the initial Contributions referred to therein. All amounts of Available Cash distributed by the Partnership on any date from any source (other than amounts paid or distributed pursuant to Section 4.2) shall be deemed to be Cash from Operations until the aggregate amount of all Available Cash theretofore distributed by the Partnership to Partners pursuant to Sections 5.4 and 5.5 equals the aggregate amount of all Cash from Operations of the Partnership from the Partnership Inception through the end of the calendar quarter immediately preceding such distribution. Any remaining amounts of Available Cash distributed by the Partnership on such date (other than amounts paid or distributed pursuant to Section 4.2) shall, except as otherwise provided in Section 5.7, be deemed to be Cash from Interim Capital Transactions. With respect to any calendar quarter included in the period beginning on (and including) the day immediately following the last day of the Series A Preference Unit Preference Period and ending on (and including) the day immediately prior to the Series B Preference Unit Preference Date, the General Partner may decide (in its sole discretion) to make a distribution in respect of each Series B Preference Unit then Outstanding (the amount of such distribution (a "Series B Preference Unit Discretionary Distribution Amount"); provided, however, that the Series B Preference Unit Discretionary Distribution Amount for any such calendar quarter shall not exceed an amount equal to the Series B Preference Unit Deficiency on the last day of such calendar quarter. 5.4 Distributions During Series A Preference Unit Preference Period.

If the holders of at least a majority of the outstanding Series A Preference Units elect to convert following the giving of any Series A Preference Unit Conversion Opportunity Notice, but the Liquidity Condition is not satisfied, the Series A Preference Unit Preference Period shall not end. (d) Notwithstanding the foregoing, the Series A Preference Unit Preference Period and the General Partner's obligation to give additional Series A Preference Unit Conversion Opportunity Notices, shall end, if not sooner ended pursuant to Section 5.6(c), as of the date of the third Series A Preference Unit Conversion Opportunity Notice. 5.7 Distributions of Cash from Interim Capital Transactions. Available Cash that is deemed to be Cash from Interim Capital Transactions shall be distributed, unless the provisions of Section 5.3 require otherwise, 99% to all Limited Partners holding Series A Common Units, Series A Preference Units Series B Preference Units (allocated between each such series and 46

among the holders of each such series as provided below in this Section 5.7) and 1.0% to the General Partner until (a) a hypothetical holder of a Series A Preference Unit acquired at the time of the Series A Preference Unit Initial Offering has received with respect to each Series A Preference Unit, from Partnership Inception through such date, distributions of Available Cash that are deemed to be Cash from Interim Capital Transactions in an aggregate amount per Series A Preference Unit equal to the Initial Unit Price, and (b) a hypothetical holder of a Series B Preference Unit has received with respect to each Series B Preference Unit, from the Series B Preference Unit Issuance Date through such date, distributions of Available Cash that are deemed to be Cash from Interim Capital Transactions in an aggregate amount per Series B Preference Unit equal to the Series B Preference Unit Liquidation Value. Thereafter, all Available Cash shall be distributed as if it were Cash from Operations and shall be distributed in accordance with Section 5.4 or 5.5, whichever is applicable. As among the Limited Partners holding Series A Common Units, Series A Preference Units and Series B Preference Units, any distributions under this Section 5.7 shall be allocated based on the Combined Unit Sharing Ratios. As among the Limited Partners holding a particular series of Units, such distributions shall be allocated in the proportion that the respective number of Units in such series held by them bears to the total number of Units in such series then Outstanding. 5.8 Definitions. As used herein, (a) "Available Cash" means, with respect to any calendar quarter: (i) the sum of: (A) all cash receipts of the Partnership during such quarter from all sources (including distributions of cash received from the Operating Companies); and (B) any reduction in reserves (including the Reserve Amount) established in prior quarters; (ii) less the sum of. (A) all cash disbursements of the Partnership during such quarter (excluding cash distribution to Unitholders and to the General Partner, but including, for example, disbursements for taxes of the Partnership as an entity, debt service and capital expenditures); (B) the amount of any voluntary addition to the Reserve Amount; (C) any reserves established and the amount of any additions to such reserves in such quarter and in such amounts as the General Partner determines to be necessary or appropriate in its reasonable discretion (x) to provide for the proper conduct of the business of the Partnership or the Operating Companies (including reserves for future capital expenditures) or (y) to provide funds for distributions with respect to any of the next four calendar quarters, in addition to the Reserve Amount; and 47

(D) any other reserves established in such quarter in such amounts as the General Partner determines in its reasonable discretion to be necessary because the distribution of such amounts would be prohibited by applicable law or by any loan agreement, security agreement, mortgage, debt instrument or other agreement or obligation to which the Partnership is a party or by which it is bound or its assets are subject. Taxes paid by the Partnership on behalf of, or amounts withheld with respect to, any of the Partners shall not be considered cash disbursements of the Partnership which reduce "Available Cash," but shall be deemed to be a distribution of Available Cash to such Partners. Alternatively, in the discretion of the General Partner, such taxes (if pertaining to all Partners) may be considered to be cash disbursements of the Partnership which reduce "Available Cash," but shall not deemed to be a distribution of Available Cash to such Partners. Notwithstanding the foregoing, "Available Cash" shall not include any cash receipts or reductions in reserves or take into account any disbursements made or reserves established after commencement of the dissolution and liquidation of the Partnership. Distributions of Available Cash will be characterized as either distributions of Cash from Operations or Cash from Interim Capital Transactions. All Available Cash distributed by the Partnership on any date from any source will be treated as if it were a distribution of Cash from Operations until the sum of all distributions of Available Cash treated as Cash from Operations is equal to the sum of (i) the balance of the Reserve Account at Partnership Inception and (ii) the aggregate amount of all Cash from Operations generated by the Partnership since Partnership Inception through the end of the prior calendar quarter, any remaining Available Cash distributed on such date will be treated as if it were a distribution of Cash from Interim Capital Transactions, except as otherwise set forth herein. (b) "Cash from Interim Capital Transactions" means at any date such amounts of Available Cash as are deemed to be Cash from Interim Capital Transactions pursuant to Section 5.3; (c) "Cash from Operations" means, at any date but prior to commencement of the dissolution and liquidation of the Partnership, on a cumulative basis: (i) the sum of: (A) the cash balance of the Partnership and the Operating Companies at the Partnership Inception after all transactions contemplated on the Closing Date, including the Reserve Amount, plus (B) all cash receipts of the Partnership and the Operating Companies from their operations (excluding any cash proceeds from any Interim Capital Transactions or from any sale, transfer or disposition of assets after commencement of the dissolution and liquidation of the Partnership) during the period from the Partnership Inception through such date; (ii) less the sum of: 48

(A) all cash operating expenditures of the Partnership and the Operating Companies during such period, including, without limitation, taxes imposed on the Partnership or the Operating Companies as an entity, (B) all cash debt service payments of the Partnership and the Operating Companies during such period (other than payments or prepayments of principal and premiums required by reason of loan agreements (including covenants and default provisions therein) or by lenders, in each case in connection with the sales or other dispositions of assets or made in connection with refinancings or refundings of indebtedness, provided that any payment or prepayment of principal, whether or not then due, may be determined at the election and in the discretion of the General Partner, to be refunded or refinanced by any indebtedness incurred or to be incurred by the Partnership or the Operating Companies simultaneously with or within 180 days prior to or after such payment or prepayment to the extent of the principal amount of such indebtedness so incurred), (C) all cash capital expenditures of the Partnership and the Operating Companies during such period (other than (x) any cash capital expenditure made for the purpose of materially increasing the capacity of the Operating Companies' pipelines and facilities (considered as a whole and assuming normal operating conditions, including downtime and maintenance), and not in connection with scheduled maintenance activities, over the capacity of such pipelines and facilities existing immediately prior to such capital expenditure and (y) any cash expenditures made in payment of transaction expenses relating to Interim Capital Transactions), (D) any reserves outstanding as of such date which are required, or the General Partner determines in its reasonable discretion to be necessary or appropriate to provide for the future cash payment of items of the type referred to in clauses (AA) through (CC) of this sentence, and (E) any reserves (other than the Reserve Amount) outstanding as of such date that the General Partner determines to be necessary or appropriate in its reasonable discretion to provide funds for distributions on a consolidated basis and after elimination of intercompany items and the Company's non-managing interest in the Operating Companies. Taxes paid by the Partnership on behalf of, or amounts withheld with respect to, any of the Partners shall not be considered cash operating expenditures of the Partnership which reduce "Cash from Operations," but shall be deemed to be a distribution of Available Cash to such Partners. Alternatively, in the discretion of the General Partner, such taxes (if pertaining to all Partners) may be considered to be cash disbursements of the Partnership which reduce "Cash from Operations," but shall not be deemed to be a distribution of Available Cash to such Partners. 49

(d) "First Target Distribution" means $0.65 ($0.325 on and after the 1996 Split Date) per Unit per calendar quarter (or, with respect to the period commencing on the Closing Date and ending on March 31, 1993, the product of $0.65 multiplied by a fraction of which the numerator is the number of days in such period and of which the denominator is 90), subject to adjustment in accordance with Sections 5.9 and 9.6; (e) "Interim Capital Transactions" means (i) borrowings, refinancings or refundings of indebtedness and sales of debt securities (other than for working capital purposes and for items purchased on open account in the ordinary course of business) by the Partnership or the Operating Companies, (ii) sales of equity interests by the Partnership or the Operating Companies and (iii) sales or other voluntary or involuntary dispositions of any assets of the Partnership or the Operating Companies (other than (x) sales or other dispositions of inventory in the ordinary course of business, (y) sales or other dispositions of other current assets including amounts receivable or (z) sales or other dispositions of assets as a part of normal retirements or replacements), in each case prior to the commencement of the dissolution and liquidation of the Partnership; (f) "Minimum Quarterly Distribution" means $0.55 ($0.275 on and after the 1996 Split Date) per Unit (as adjusted for Partnership Interest Adjusting Events) per calendar quarter (or, with respect to the period commencing on the Closing Date and ending on March 31, 1993, the product of $0.55 (as adjusted for Partnership Interest Adjusting Events) multiplied by a fraction of which the numerator is the number of days in such period and of which the denominator is 90), subject to adjustment in accordance with Sections 5.9 and 9.6; (g) "Net Income" means, for any taxable period, the excess, if any, of the Partnership's items of income and gain (other than those items attributable to dispositions constituting Termination Capital Transactions) for such taxable period over the Partnership's items of loss and deduction (other than these items attributable to dispositions constituting Termination Capital Transactions) for such taxable period. The items included in the calculation of Net Income shall be determined in accordance with Section 4.6(b) and shall not include any items specially allocated under Section 5.1(e) or 5.1(e). Once an item of income, gain, loss or deduction that has been included in the initial computation of Net Income is subject to a Required Allocation or a Discretionary Allocation, the applicable Net Income or Net Loss shall be recomputed without regard to such item. For purposes of Sections 5.1(a) and 5.1(b), in determining whether Net Income has been allocated to any Unit or any Partner (as the case may be) for any previous taxable period, any Unrealized Gain or Unrealized Loss allocated pursuant to Section 4.6(d) shall be treated as item of gain or loss in computing Net Income; (h) "Net Loss" means, for any taxable period, the excess, if any, of the Partnership's items of loss and deduction (other than those items attributable to dispositions constituting Termination Capital Transactions) for such taxable period over the Partnership's items of income and gain (other than those items attributable to dispositions constituting Termination Capital Transactions) for such taxable period. The items included in the calculation of Net Loss shall be determined in accordance with Section 4.6(b) and shall not include any items specifically allocated under Section 5.1(e) or 5.1(e).

regard to such item.

(b) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution, Third Target Distribution and the amount distributed under may be adjusted under the circumstances, and in the manner, set forth in Section 9.6. 5.10 Reserve Amount. The Partnership shall establish the Reserve Amount, consisting of the aggregate cash on hand in the Partnership and the Operating Companies at Partnership Inception, on a combined basis, increased by net cash proceeds to the Partnership from the exercise by the Underwriters of the over-allotment option described in Section 4.3(c) hereof, which shall be deemed to occur for purposes of determination of the Reserve Amount at Partnership Inception. The Reserve Amount shall be an asset of the Partnership, need not be maintained separate or apart from any other reserves, accounts or assets of the Partnership and shall be utilized, in the sole discretion of the General Partner, for any proper Partnership purpose, including but not limited to stabilizing distributions to Unitholders, debt reduction, capital expenditures, additional funding of the Reserve Amount or the establishment or increase of other appropriate reserves. The General Partner, in its sole discretion, may elect to retain in the Reserve Amount any balance therein and may voluntarily increase or decrease the Reserve Amount, from time to time, and need not justify such retention increase or decrease as being for any particular Partnership purpose. The balance in the Reserve Amount shall be disregarded in determining the need for or amounts of other reserves which the General Partner is authorized to establish and maintain pursuant to this Agreement. 5.11 Special Distributions. (a) On the Optional Closing Date (as defined in the Underwriting Agreement), the General Partner shall surrender to the Partnership a number of Common Units equal to the number of Series A Preference Units acquired by the Underwriters in excess of 393,750 Series A Preference Units in exchange for a per Unit distribution equal to the Issue Price per Unit. 52

Prior to the Closing Date, the General Partner caused the Certificate of Limited Partnership (in its form at such time) to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents as may be determined by the General Partner in its sole discretion to be reasonable and necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent 54

that such action is determined by the General Partner in its sole discretion to be reasonable and necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 7.5(a), the General Partner shall not be required before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner or Assignee. 6.3 Restrictions on General Partner's Authority.

Without the approval of the holders of at least a majority of the Outstanding Series A Preference Units during the Series A Preference Unit Preference Period and thereafter without the approval of the holders of at least a majority of the Outstanding Voting Units, the General Partner shall not, on behalf of the Partnership, consent to any amendment to the Operating Companies' Agreements that would adversely affect the Partnership as a member of the Operating Companies. In no event shall all or substantially all of the Partnership's assets be sold, exchanged or otherwise disposed of in a single transaction or a series of related transactions (including by way of merger, consolidation or other combination with any other Person) without the approval of the General Partner.

Preference Units, (other than Preference Units held by the General Partner and its affiliates), the General Partner shall not take any action or refuse to take any reasonable action the effect of which, if taken or not taken, as the case may be, would be to cause the Partnership or, to the extent it would materially and adversely affect the Limited Partners holding Units, the Operating Companies to be taxable as a corporation or otherwise taxed as an entity for federal income tax purpose; provided that this Section 6.3(c) shall not be construed to apply to amendments to this Agreement (which are governed by Article XV) or mergers or consolidations of the Partnership with any Person (which are governed by Article XVI). (d) At all times while serving as the general partner of the Partnership, the General Partner shall not make any dividend or distribution on, repurchase any shares of its stock, or take any other action within its control if the effect of such dividend distribution, repurchase or other action (i) would cause it hold less than 19% of the Outstanding Units and (ii) would be to reduce its net worth below an amount necessary to receive an Opinion of Counsel that the Partnership will be treated as a partnership for federal income tax purposes. (e) (i) Notwithstanding any other provision of this Agreement, the General Partner is not authorized to institute or initiate on behalf of, or otherwise cause, the Partnership or any of the Operating Companies to, (A) make a general assignment for the benefit of creditors; (B) file a voluntary bankruptcy petition; (C) file a petition seeking for the Partnership or any of the Operating Companies a reorganization, arrangement, composition, readjustment liquidation, dissolution or similar relief under any law; or (D) seek the appointment of a trustee, receiver or liquidator of the Partnership or any of the Operating Companies or of all or any substantial part of any of the properties of any of them, unless such action has been approved by all of the directors on the General Partner's board of directors. (ii) No provision of this Section 6.3(e) shall be amended, altered, changed, repealed or rescinded in any respect unless such amendment is approved by the written consent or the affirmative vote of all of the directors on the General Partner's board of directors. 6.4 Reimbursement of the General Partner. (a) Except as provided in this Section 6.4 and elsewhere in this Agreement, the General Partner shall not be compensated for its services as general partner of the Partnership. (b) The General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine in its sole discretion, for (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership (including, without limitation, 56

Any accruals by the General Partner of the expected cost of providing all forms of post-retirement benefits to employees or former employees of the General Partner and their beneficiaries and qualified dependents will be borne by the Partnership, to the extent properly allocable thereto. The General Partner shall determine the fees and expenses that are allocable to the Partnership in any reasonable manner determined by the General Partner in its sole discretion.

(a) The General Partner agrees that so long as it is the General Partner of the Partnership, it will not engage in or acquire, directly or indirectly, any business that is in direct material competition with the business of the Partnership, subject to the following exceptions: (i) First, the Company may acquire any competitive business as part of a larger acquisition, so long as 75% or more of the revenues of the business acquired, in the Company's reasonable judgment, are not derived from such competitive business, provided however, if it is commercially and operationally practicable, the Company will use its reasonable efforts to offer that portion of the competitive business to the Partnership; and (ii) Second, the Company may engage in or acquire any competitive business if the same is first offered to the Partnership and the Partnership declines by a majority vote of the outstanding Units (excluding for this purpose any Units held by the General Partner or any of its affiliates) to make such acquisition or engage in such business. (b) Except as otherwise expressly provided in Section 6.5(a), each Indemnitee is free to engage in any business, including any business that is in competition with the business of the Partnership. The General Partner and any other Persons affiliated with the General Partner may acquire Units or other Partnership Securities, in addition to those acquired by any of such 57

Persons on the Closing Date, and (except as the right to vote such Units or other Partnership Securities may be expressly limited in this Agreement) shall be entitled to exercise all rights of an Assignee or Limited Partner, as applicable, relating to such Units or Partnership Securities, as the case may be. (c) Without limiting Sections 6.5(a) and 6.5(b), but notwithstanding any other provision to the contrary in this Agreement, the competitive activities of Indemnitees described in the Registration Statement are hereby approved by all Partners and it shall not be deemed to be a breach of the General Partner's fiduciary duty for the General Partner to permit an Indemnitee to engage in a business opportunity in preference to or to the exclusion of the Partnership. 6.6 Loans to and from the General Partner; Contracts with Affiliates. (a) The General Partner or any Affiliate thereof may lend to the Partnership or the Operating Companies, and the Partnership and the Operating Partnership may borrow, funds needed or desired by the Partnership and the Operating Companies for such periods of time as the General Partner may determine and (b) the General Partner or any Affiliate thereof may borrow from the Partnership or the Operating Companies, and the Partnership and the Operating Companies may lend to the General Partner or any Affiliate thereof, excess funds of the Partnership and the Operating Companies for such periods of time and in such amounts as the General Partner may determine; provided, however, that in either case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party (without reference to the General Partner's financial abilities or guarantees), by unrelated lenders on comparable loans. The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by it in connection with the borrowing of such funds. For purpose of this Section 6.6(a) and Section 6.6(b), the term "Partnership" shall include any Affiliate of the Partnership that is controlled by the Partnership and the term "Operating Companies" shall include any Affiliate of the Operating Companies that is controlled by the Operating Companies. (b) The Partnership may lend or contribute to the Operating Companies, and the Operating Companies may borrow, funds on terms and conditions established in the sole discretion of the General Partner; provided, however, that the Partnership may not charge the Operating Companies interest at a rate greater than the rate that would be charged to the Operating Companies, (without reference to the General Partner's financial abilities or guarantees), by unrelated lenders on comparable loans. The foregoing authority shall be exercised by the General Partner in its sole discretion and shall not create any right or benefit in favor of the Operating Companies or any other Person. (c) The General Partner may itself, or may enter into an agreement with any of its Affiliates to, render services to the Partnership. Any service rendered to the Partnership by the General Partner or any of its Affiliates shall be on terms that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 6.6(c) shall be deemed satisfied as to any transaction the terms of which are no less favorable to the Partnership than those generally being provided to or available from unrelated third parties. The provisions of Section 6.4 shall apply to the rendering of services described in this Section 6.6(c). 58

(d) The Partnership may transfer assets to joint venture, other partnerships, corporations or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions as are consistent with this Agreement and applicable law. (e) Neither the General Partner nor any of its Affiliates shall sell, transfer or convey any property to, or purchase any property from, the Partnership, directly or indirectly, except pursuant to transactions that are fair and reasonable to the Partnership; provided, however, that the requirements of this Section 6.6(e) shall be deemed to be satisfied as to (i) the transactions effected pursuant to Sections 4.2 and 4.3, the Conveyance Agreement and any other transactions described in or contemplated by the Registration Statement and (ii) as to any transaction the terms of which are no less favorable to the Partnership than those generally being provided to or available from unrelated third parties. (f) The General Partner and its Affiliates shall have no obligation to permit the Partnership or the Operating Companies to use any facilities of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use, nor shall there be any obligation of the General Partner or its Affiliates to enter into such contracts. (g) Without limitation of Section 6.6(a) through 6.6(f), and notwithstanding anything to the contrary in this Agreement, the existence of the conflicts of interest described in the Registration Statement are hereby approved by all Partners. 6.7 Indemnification. (a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, the General Partner, any Departing Partner and any person who is or was an officer or director of the General Partner or any Departing Partner shall be indemnified and held harmless by the Partnership, and all other Indemnitees may be indemnified and held harmless by the Partnership, to the extent deemed advisable by the General Partner, from and against any and all losses, claims, damages, liabilities (joint or several), expenses (including, without limitation, legal fees and expenses), judgments, fines settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as (i) the General Partner, Departing Partner or any of their Affiliates, (ii) an officer, director, employee, partner, agent or trustee of the General Partner, any Departing Partner or any of their Affiliates or (iii) a Person serving at the request of the Partnership in another entity in a similar capacity; provided, that in each case the Indemnitee acted in good faith, in a manner which such Indemnitee believed to be in, or not opposed to, the best interests of the Partnership and, with respect to any criminal proceeding, had no reasonable cause to believe its conduct was unlawful; provided further, no indemnification pursuant to this Section 6.7 shall be available to the General Partner with respect to its obligations incurred pursuant to the Underwriting Agreement or the Conveyance Agreement (other than obligations incurred by the General Partner on behalf of the Partnership or the Operating Companies). The termination of any action, suit or proceeding by judgment, order settlement conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitee acted in a manner contrary to that specified above. Any 59

indemnification pursuant to this Section 6.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification. (b) To the fullest extent permitted by law, expenses (including, without limitation, reasonable legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 6.7(a) in defending any claim, demand action, suit or proceeding shall from time to time, be advanced by the Partnership prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Partnership of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 6.7. (c) The indemnification provided by this Section 6.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the Partners, as a matter of law or otherwise, both as to actions in the Indemnities' capacity as (i) the General Partner, a Departing Partner or an Affiliate thereof, (ii) an officer, director, employee, partner, agent or trustee of the General Partner, any Departing Partner or an Affiliate thereof or (iii) a Person serving at the request of the Partnership in another entity in a similar capacity (including, without limitation, any capacity under the Underwriting Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and as to actions in any other capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnities. (d) The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Partnership's activities, whether or not the Partnership would have the power to indemnify such Person against such liabilities under the provisions of this Agreement. (e) For purposes of this Section 6.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law she constitute "fines" within the meaning of Section 6.7(a); and action taken or omitted by it with respect to an employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Partnership. (f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement. (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 6.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 60

(h) The provisions of this Section 6.7 are for the benefit of the Indemnities, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. (i) No amendment, modification or repeal of this Section 6.7 or any other provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligation of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 6.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 6.8 Liability of Indemnitees. (a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damage to the Partnership, the Limited Partners, the Assignees or any other Persons who have acquired interests in the Units, for losses sustained or liabilities incurred as a result of any act or omission if such Indemnitee acted in good faith. (b) Subject to its obligations and duties as General Partner set forth in Section 6.1(a), the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith. (c) Any amendment, modification or repeal of this Section 6.8 or any other provision hereof shall be prospective only and shall not in any way affect the limitations on the liability to the Partnership and the Limited Partners of the General Partner, its directors, officers and employees under this Section 6.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 6.9 Resolution of Conflict of Interest. (a) Unless otherwise expressly provided in this Agreement or an Operating Companies Agreement, whenever a potential conflict of interest exists or arise between the General Partner or any of its Affiliates, on the one hand, and the Partnership, the Operating Companies, any Partner or any Assignee, on the other hand, any resolution or course of action in respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of the Charter Documents of any Operating Company, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action is or, by operation of this Agreement, is deemed to be, fair and reasonable to the Partnership. The General Partner shall be authorized, but not required in connection with its resolution of such conflict of interest to seek Special 61

Approval of a resolution of such conflict or course of action. Any conflict of interest and any resolution of such conflict of interest shall be conclusively deemed fair and reasonable to the Partnership if such conflict of interest or resolution is (i) approved by Special Approval, (ii) on whole, on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iii) fair to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner may also adopt a resolution or course of action that has not received Special Approval. The General Partner (including the Conflicts and Audit Committee in connection with Special Approval) shall be authorized in connection with its determination of the "fair and reasonable" nature of any transaction or arrangement and in its resolution of any conflict of interest to consider (i) the relative interests of any party to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interest; (ii) any customary or accepted industry practices and any customary or historical dealings with a particular Person; (iii) any applicable generally accepted accounting or engineering practices or principles; and (iv) such additional factors as the General Partner or such Conflicts and Audit Committee determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. Nothing contained in this Agreement, however, is intended to nor shall it be construed to require the General Partner or such Conflicts and Audit Committee to consider the interests of any Person other than the Partnership. In the absence of bad faith by the General Partner, the resolution, action or terms so made, taken or provided by the General Partner with respect to such matter shall not constitute a breach of this Agreement or any other agreement contemplated herein or a breach of any standard of care or duty imposed herein or therein or under the Delaware Act or any other law, rule or regulation. (b) Whenever this Agreement or any other agreement contemplated hereby provides that the General Partner or any of its Affiliates is permitted or required to make a decision (i) in its "sole discretion" or "discretion" that it deems "necessary or appropriate" or under a grant of similar authority or latitude, the General Partner or such Affiliate shall be entitled to consider only such interests and factors as it desires and shall have no duty or obligation to give any consideration to any interest of, or factors affecting, the Partnership, the Operating Companies, any Limited Partner or any Assignee, (ii) it may make such decision in its sole discretion (regardless of whether there is a reference to "sole discretion" or "discretion") unless another express standard is provided for, or (iii) a "good faith" or under another express standard, the General Partner or such Affiliate shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement, the Charter Documents of any Operating Company, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation. In addition, any actions taken by the General Partner consistent with the standards of "reasonable discretion" set forth in the definitions of Available Cash or Cash from Operations shall not constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners. During or after the Series A Preference Unit Preference Period, the General Partner shall have no duty, express or implied, to sell or otherwise dispose of any asset of the Operating Companies or of the Partnership, other than in the ordinary course of business. No borrowing by the Partnership or the Operating Companies or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty of the General Partner to the Partnership or the Limited Partners by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to reduce or avoid the need to draw upon the Reserve Amount to make Minimum Quarterly Distributions on the Series A Preference Units, to make 62

distributions up to the Series B Preference Unit Deficiency on the Series B Preference Units, to permit distributions on Series A Common Units or to result in or increase incentive distributions to the General Partner. (c) Whenever a particular transaction, arrangement or resolution of a conflict of interest is required under this Agreement to be "fair and reasonable" to any Person, the fair and reasonable nature of such transaction, arrangement or resolution shall be considered in the context of all similar or related transaction. 6.10 Other Matters Concerning the General Partner. (a) The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request consent, order, bond, debenture, or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties. (b) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it and any act taken or omitted in reliance upon the opinion (including, without limitation, an Opinion of Counsel) of such Persons as to matters that the General Partner reasonably believes to be within such Person's professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion. (c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers and a duly appointed attorney or attorneys-in-fact. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform each and every act and duty that is permitted or required to be done by the General Partner hereunder. (d) Any standard of care and duty imposed by this Agreement or under the Delaware Act or any applicable law, rule or regulation shall be modified waived or limited as required to permit the General Partner to act under this Agreement or any other agreement contemplated by this Agreement and to make any decision pursuant to the authority prescribed in this Agreement, so long as such action is reasonably believed by the General Partner to be in, or not inconsistent with, the best interests of the Partnership. 6.11 Title to Partnership Assets. Title to Partnership Assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner or Assignee, individually or collectively, shall have any ownership interest in such Partnership Assets or any portion thereof. Title to any or all of the Partnership Assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine. The General Partner hereby declares and warrants that any Partnership assets for which record title is held in the name of the General Partner shall be held by the General Partner for the exclusive use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use its reasonable efforts to cause record title to such assets (other than those assets in respect of which the General Partner determines that the expense and difficulty of conveyancing makes transfer of 63

record title to the Partnership impracticable) to be vested in the Partnership as soon as reasonably practicable; provided, that prior to the withdrawal or removal of the General Partner or as soon thereafter as practicable, the General Partner will use reasonable efforts to effect the transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such assets in a manner satisfactory to the Partnership. All Partnership Assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which record title to such Partnership assets are held. 6.12 Purchase or Sale of Preference Units. The General Partner may cause the Partnership to purchase or otherwise acquire Series A Preference Units, so long as no Series A Preference Unit Cumulative Deficiency then exists, and Series B Preference Units, at any time. As long as Preference Units are held by the Partnership or the Operating Companies, such Preference Units shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Preference Units for its own account, subject to the provisions of Article XI and Article XII. 6.13 Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner as if it were the Partnership's sole party in interest, both legally and beneficially. Each Limited Partner hereby waives any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of the General Partner in connection with any such dealing. In no event shall any Person dealing with the General Partner or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement, and is binding upon the Partnership 6.14 Registration Rights of the General Partner and its Affiliates. (a) If (i) the General Partner or any of its Affiliates (including for purposes of this Section 6.14, Persons that are Affiliates on the Second Restatement Date notwithstanding that they may later cease to be Affiliates) hold Units or other Partnership Securities which it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) is not available to enable the General Partner or such Affiliates to dispose of the number of Units or other Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then upon the request of the General Partner or any of its Affiliates, the Partnership shall file with the Securities and Exchange Commission as promptly as practicable 64

after receiving such request, and use all reasonable efforts to cause to become effective and remain effective for a reasonable period following its effective date, a registration statement or statements under the Securities Act registering the offering and sale of the number of Units or other Partnership Securities specified in the request. All registrations requested pursuant to this Section 6.14(a) are referred to as "Demand Registrations." The Partnership may postpone for up to six months the filing or the effectiveness of a registration statement pursuant to a Demand Registration if (i) the General Partner or, (ii) if at the time a request for Demand Registration is submitted to the Partnership the Person requesting registration is an Affiliate of the General Partner, a majority of the independent directors of the General Partner, determines in its good faith judgment that a postponement of the requested registration for up to six months would be in the best interests of the Partnership and its Partners due to a pending transaction, investigation or other event. In connection with any Demand Registration, the Partnership shall promptly prepare and file (x) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Persons requesting registration shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation doing business in such jurisdiction, and (y) such documents as may be necessary to apply for listing or to list the securities subject to such registration on such National Securities Exchange as the Persons requesting registration shall reasonably request and do any and all other acts and things that may reasonably be necessary or advisable to enable such Persons to consummate a public sale of such securities in such states. All costs and expenses of any such Demand Registration and offering (other than the underwriting discounts and commissions) shall be borne by the Partnership. (b) If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of securities of the Partnership for cash (other than an offering relating solely to an employee benefit plan), the Partnership shall use all reasonable efforts to include such number or amount of securities held by the General Partner and any of its Affiliates in such registration statement as the General Partner or any of such Affiliates shall request. All registrations requested pursuant to this Section 6.14(b) are referred to herein as "Piggyback Registrations." If the proposed offering shall be an underwritten offering, then, in the event that the managing underwriter of such offering advises the Partnership and General Partner or any of such Affiliates in writing that in its opinion the inclusion of all or some of the securities of the Persons requesting Piggyback Registration would adversely and materially affect the success of the offering the Partnership shall include in such offering only that number or amount, if any, of securities of the Persons requesting Piggyback Registration which, in the opinion of the managing underwriter, will not so adversely and materially affect the offering. All costs and expenses of such registration and offering (other than underwriting discounts and commissions attributable to securities registered by the General Partner and its Affiliates) shall be borne by the Partnership. (c) If underwriters are engaged in connection with any Demand or Piggyback Registration, the Partnership shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Partnership's obligation under Section 6.7, the Partnership shall, to the fullest extent permitted by law, indemnify and hold 65

harmless the General Partner or such other holder, its officers, directors and each Person who controls the General Partner or such other holder (within the meaning of the Securities Act) and any agent thereof (collectively, "Indemnified Persons") against any losses, claims, demands, actions, causes of action, assessments, damages, liabilities (joint or several), costs and expenses (including, without limitation, interest penalties and reasonable attorneys' fees and disbursements), resulting to, imposed upon, or incurred by an Indemnified Person, directly or indirectly, under the Securities Act or otherwise (hereinafter referred to in this Section 6.14(c) as a "claim" and in the plural as "claims"), based upon, arising out of, or resulting from any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which any securities were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading; provided, however, that the Partnership shall not be liable to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, such preliminary, summary or final prospectus or such amendment or supplement in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof. (d) The provisions of Sections 6.14(a) and 6.14(b) shall continue to be applicable with respect to the General Partner and any of its Affiliates after the General Partner ceases to be a Partner of the Partnership, during a period of two years subsequent to the effective date of such cessation and for so long thereafter as is required for the General Partner or any of its Affiliates to sell all of the Units or other Partnership Securities with respect to which the General Partner or any of its Affiliates have requested during such two-year period that a registration statement be filed; provided, however, that the Partnership shall not be required to file successive registration statements covering the same securities for which registration was demanded during such two-year period. The provisions of Section 6.14(c) shall continue in effect thereafter. (e) Any request to register Partnership Securities pursuant to this Section 6.14 shall (i) specify the Partnership Securities intended to be offered and sold by the Person making the request, (ii) express such Person's present intent to offer such shares for distribution, (iii) describe the nature or method of the proposed offer and sale of Partnership Securities, and (iv) contain the undertaking of such Person to provide all such information and materials and take all action as may be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Partnership Securities. ARTICLE VII RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS 7.1 Limitation of Liability. The Limited Partners and the Organizational Limited Partner and the Assignees shall have no liability under this Agreement except as expressly provided in this Agreement or the Delaware Act. 66

7.2 Management of Business. No Limited Partner or Assignee (other than the General Partner, any of its Affiliates or any officer, director, employee partner, agent or trustee of the General Partner or any of its Affiliates, in its capacity as such, if such Person shall also be a Limited Partner or Assignee) shall take part or otherwise participate in the operation, management or control (within the meaning of the Delaware Act) of the Partnership's business, transact any business in the Partnership's name or have the power to sign documents for or otherwise bind the Partnership. The transaction of any such business by the General Partner, any of its Affiliates or any officer, director, employee, partner, agent or trustee of the General Partner or any of its Affiliates, in its capacity as such, shall not affect, impair or eliminate the limitations on the liability of the Limited Partners or Assignees under this Agreement. 7.3 Outside Activities. Subject to the provisions of Section 6.5, which shall continue to be applicable to the Persons referred to therein, regardless of whether such Persons shall also be Limited Partners or Assignees, any Limited Partner or Assignee shall be entitled to and may have business interests and engage in business activities in addition to those relating to the Partnership, including, without limitation, business interests and activities in direct competition with the Partnership or the Operating Companies. Neither the Partnership nor any of the other Partners or Assignees shall have any rights by virtue of this Agreement in any business ventures of any Limited Partner or Assignee. 7.4 Return of Capital. No Limited Partner shall be entitled to the withdrawal or return of his Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon termination of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent provided by Article V or as otherwise expressly provided in this Agreement, no Limited Partner or Assignee shall have priority over any other Limited Partner or Assignee either as to the return of Capital Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners and Assignees agree within the meaning of Section 17-502(b) of the Delaware Act. 7.5 Rights of Limited Partner Relating to the Partnership. (a) In addition to other rights provided by this Agreement or by applicable law, and except as limited by Section 7.5(b), each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner's interest as a limited partner in the Partnership, upon reasonable demand and at such Limited Partner's own expense: (i) to obtain true and full information regarding the status of the business and financial condition of the Partnership; (ii) promptly after becoming available, to obtain a copy of the Partnership's federal, state and local tax returns for each year; (iii) to have furnished to him, upon notification to the General Partner, a current list of the name and last known business, residence or mailing address of each Partner; 67

(iv) to have furnished to him, upon notification to the General Partner, a copy of this Agreement and the Certificate of Limited Partnership and all amendments thereto; (v) to obtain true and full information regarding the amount of cash and description and statement of the Agreed Value of any other Capital Contribution by each Partner and which each Partner has agreed to contribute in the future, and the date on which each became a Partner; and (vi) to obtain such other information regarding the affairs of the Partnership as is just and reasonable. (b) Notwithstanding any other provision of this Agreement, the General Partner may keep confidential from the Limited Partners and Assignees for such period of time as the General Partner deems reasonable, any information that the General Partner reasonably believes to be in the nature of trade secrets or other information the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or could damage the Partnership or the Operating Companies or that the Partnership or the Operating Companies is required by law or by agreements with third parties to keep confidential (other than agreements with Affiliates the primary purpose of which is to circumvent the obligations set forth in this Section 7.5). ARTICLE VIII BOOK, RECORDS, ACCOUNTING AND REPORTS 8.1 Records and Accounting. The General Partner shall keep or cause to be kept at the principal office of the Partnership appropriate books and records with respect to the Partnership's business, including, without limitation, all books and records necessary to provide to the Limited Partners any information, lists and copies of documents required to be provided pursuant to Section 7.5(a). Any books and records maintained by or on behalf of the Partnership in the regular course of its business, including, without limitation, the record of the Record Holders and Assignees of Units or other Partnership Securities, books of account and records of Partnership proceedings, may be kept on, or be in the form of, computer disks, hard disks, punch cards, magnetic tape, photographs, micrographics or any other information storage device, provided that the books and records so maintained are convertible into clearly legible written form within a reasonable period of time. The books of the Partnership shall be maintained for financial reporting purposes, on an accrual basis in accordance with generally accepted accounting principles. 8.2 Fiscal Year. The fiscal year of the Partnership shall be the calendar year. 8.3 Reports. (a) As soon as practicable, but in no event later than 120 days after the close of each Partnership Year, the General Partner shall cause to be mailed to each Record Holder of a Unit as of a date selected by the General Partner in its sole discretion, an annual report containing financial statements of the Partnership for such Partnership Year, presented in accordance with generally accepted accounting principles, including a balance sheet and statements of operations, 68

Partners' equity and cash flows, such statements to be audited by a firm of independent public accountants selected by the General Partner. (b) As soon as practicable, but in no event later than 90 days after the close of each calendar quarter except the last calendar quarter of each Partnership Year, the General Partner shall cause to be mailed to each Record Holder of a Unit, as of a date selected by the General Partner in its sole discretion, a report containing unaudited financial statements of the Partnership and such other information as may be required by applicable law, regulation or rule of any National Securities Exchange on which the Units are listed for trading or as the General Partner determines to be necessary or appropriate. ARTICLE IX TAX MATTERS 9.1 Preparation of Tax Return. The General Partner shall arrange for the preparation and timely filing of all returns of Partnership income, gains, deductions, losses and other items required of the Partnership for federal and state income tax purposes and shall use reasonable efforts to furnish, within 90 days of the close of each taxable year of the Partnership, the tax information reasonably required by Unitholders for federal and state income tax reporting purposes. The classification, realization and recognition of income, gain, losses and deductions and other items shall be on the accrual method of accounting for federal income tax purposes. The taxable year of the Partnership shall be the calendar year. 9.2 Tax Elections. Except as otherwise provided herein, the General Partner shall in its sole discretion, determine whether to make any available election pursuant to the Code; provided, however, that the General Partner shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder. The General Partner shall have the right to seek to revoke any such election (including, without limitation, the election under Section 754 of the Code) upon the General Partner's determination in its sole discretion that such revocation is in the best interest of the Limited Partners and Assignees. For purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required), to adopt a convention whereby the price paid by a transferee of Units will be deemed to be the lowest quoted trading price of the Units on any National Securities Exchange on which such Units are traded during the calendar month in which such transfer is deemed to occur pursuant to Section 5.2(g) without regard to the actual price paid by such transferee. 9.3 Tax Controversies. Subject to the provisions hereof, the General Partner is designated the Tax Matters Partner (as defined in Section 6231 of the Code), and is authorized and required to represent the Partnership (at the Partnership's expense) in connection with all examinations of the Partnership's affairs by tax authorities, including, without limitation, resulting administrative and judicial proceedings, and to expend Partnership funds for professional services and costs associated therewith. Each Partner and Assignee agrees to cooperate with the General Partner and to do or refrain from doing any or all things reasonably required by the General Partner to conduct such proceedings. 69

9.4 Organizational Expenses. The Partnership shall elect to deduct expenses, if any, incurred by it in organizing the Partnership ratably over a 60-month period as provided in Section 709 of the Code. 9.5 Withholding. Notwithstanding any other provision of this Agreement, the General Partner is authorized to take any action that it determines in its sole discretion to be necessary or appropriate to cause the Partnership and the Operating Companies to comply with any withholding requirements established under the Code or any other federal, state or local law, including, without limitation, pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the extent that the Partnership is required to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income to any Partner or Assignee (including, without limitation, by reason of Section 1446 of the Code), the amount withheld shall be treated as a distribution of cash for purposes of Section 4.6(a) in the amount of such withholding from such Partner. 9.6 Entity-Level Taxation. If legislation is enacted which causes the Partnership to become treated as an association taxable as a corporation for federal income tax purposes, then (a) with respect to any calendar quarter thereafter, the Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, as the case may be, shall be equal to the product of (i) each such distribution amount multiplied by (ii) 1 minus the sum of (x) the expected effective federal income tax rate applicable to the Partnership (expressed as a decimal) plus (y) the expected effective overall state and local income tax rate applicable to the Partnership (expressed as a decimal), in each case, for the taxable year in which such quarter occurs (after taking into account the benefit of any deduction allowable for federal income tax purposes with respect to the payment of state and local income taxes) (the "Rate"); and (b) for purposes of determining the distributed amount under clauses (ii) and (iii) of the definition of "Series A Preference Unit Conversion Date," the amount of an actual distribution after such legislation is effective shall be deemed to be the actual distribution divided by the Rate. 9.7 Entity-Level Deficiency Collections. If the Partnership is required by applicable law to pay any federal, state or local income tax on behalf of, or withhold such amount with respect to, any Partner or Assignee or any former Partner or Assignee (a) the General Partner shall cause the Partnership to pay such tax on behalf of such Partner or Assignee or former Partner or Assignee from the funds of the Partnership; (b) any amount so paid on behalf of, or withheld with respect to, any Partner or Assignee shall be treated as a distribution of cash to such Partner or Assignee for purposes of this Agreement, including Section 4.6(a); and (c) to the extent any such Partner or Assignee (but not a former Partner or Assignee) is not then entitled to such distribution under this Agreement, the General Partner shall be authorized without the approval of any Partner or Assignee, to amend this Agreement insofar as is necessary to maintain the uniformity of intrinsic tax characteristics as to all Units and to make subsequent adjustments to distributions in a manner which, in the reasonable judgment of the General Partner, will make as little alteration as practicable in the priority and amount of distributions otherwise applicable under this Agreement and will not otherwise alter the distributions to which Partners and Assignees are entitled under this Agreement. If the Partnership is permitted (but not required) by applicable law to pay any such tax on behalf of any Partner or Assignee or former Partner or Assignee, the General Partner shall be authorized (but not required) to cause the Partnership to 70

pay such tax from the funds of the Partnership and to take any action consistent with this Section 9.7. The General Partner shall be authorized (but not required) to take all necessary or appropriate actions to collect all or any portion of a deficiency in the payment of any such tax that relates to prior periods and that is attributable to Persons who were Limited Partners or Assignee when such deficiencies arose, from such Persons. 9.8 Opinions of Counsel. Notwithstanding any other provision of this Agreement, if the Partnership is taxable for federal income tax purposes as a corporation or otherwise taxed for federal income tax purposes as an entity at any time and, pursuant to the provisions of this Agreement, an Opinion of Counsel would otherwise be required to the effect that an action will not cause the Partnership to become so taxable as a corporation or other entity or to be treated as an as association taxable as a corporation, such requirement for an Opinion of Counsel shall be deemed automatically waived. ARTICLE X UNIT CERTIFICATE 10.1 Unit Certificates. Unit Certificates shall be executed on behalf of the Partnership by any officer of either the General Partner or the Partnership. 10.2 Registration, Registration of Transfer and Exchange. (a) The General Partner shall cause to be kept on behalf of the Partnership a register (the "Unit Register") in which, subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 10.2(b), the General Partner will provide for the registration and the transfer of Units. The Transfer Agent is hereby appointed registrar and transfer agent for the purpose of registering and transferring Units as herein provided. The Partnership shall not recognize transfers of Certificates representing Units unless same are effected in the manner described in this Section 10.2. Upon surrender for registration of transfer of any Units evidenced by a Certificate and subject to the provisions of Section 10.2(b), the General Partner on behalf of the Partnership will execute, and the Transfer Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Certificates evidencing the same aggregate number of Units as was evidenced by the Certificate so surrendered. (b) Except as otherwise provided in Section 11.5, the Partnership shall not recognize any transfer of Units until the Certificates (if applicable) evidencing such Units are surrendered for registration of transfer and such Certificates are accompanied by a Transfer Application duly executed by the transferee (or the transferee's attorney-in-fact duly authorized in writing). No charge shall be imposed by the Partnership for such transfer, provided, that, as a condition to the issuance of any new Certificate under this Section 10.2, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto. 10.3 Mutilated, Destroyed, Lost or Stolen Certificates. (a) If any mutilated Certificate is surrendered to the Transfer Agent, the General Partner on behalf of the Partnership shall execute, and upon its request, the Transfer Agent shall 71

countersign and deliver in exchange therefor, a new Certificate evidencing the same number of Units as the Certificate so surrendered. (b) The General Partner on behalf of the Partnership shall execute, and upon its request, the Transfer Agent shall countersign and deliver a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate: (i) makes proof by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate has been lost, destroyed or stolen; (ii) requests the issuance of a new Certificate before the Partnership has received notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim; (iii) if requested by the General Partner, delivers to the Partnership a bond or such other form of security or indemnity as may be required by the General Partner, in form and substance satisfactory to the General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct, in its sole discretion, to indemnify the Partnership, the General Partner and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and (iv) satisfies any other reasonable requirements imposed by the General Partner. If a Limited Partner or Assignee fails to notify the Partnership within a reasonable time after he has notice of the loss, destruction or theft of a Certificate, and a transfer of the Units represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent receives such notification, the Limited Partner or Assignee shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate. (c) As a condition to the issuance of any Certificate under this Section 10.3, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including, without limitation, the fees and expenses of the Transfer Agent) connected therewith. 10.4 Record Holder. In accordance with Section 10.2(b), the Partnership shall be entitled to recognize the Record Holder as the Limited Partner or Assignee with respect to any Common Units or Preference Units and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Common Units or Preference Units on the part of any other Person, whether or not the Partnership shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Common Units or Preference Units are listed for trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Common Units or Preference Units, as between the Partnership on the one hand and such other Persons on 72

the other hand such representative Person (a) shall be the Limited Partner or Assignee (as the case may be) of record and beneficially, (b) must execute and deliver a Transfer Application and (c) shall be bound by this Agreement and shall have the rights and obligations of a Limited Partner or Assignee (as the case may be) hereunder and as provided for herein. ARTICLE XI TRANSFER OF INTERESTS 11.1 Transfer. (a) The term "transfer," when used in this Article XI with respect to a Partnership Interest, shall be deemed to refer to an appropriate transaction by which the General Partner assigns its Partnership Interest as General Partner to another Person or by which the holder of a Unit assigns such Unit to another Person who is or becomes an Assignee and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise. (b) No Partnership Interest shall be transferred in whole or in part, except in accordance with the terms and conditions set forth in this Article XI. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article XI shall be null and void. 11.2 Transfer of General Partner's Partnership Interest. (a) Except as set forth in this Section 11.2(a), the General Partner may transfer all, but not less than all, of its Partnership Interest as the general partner to a single transferee if, but only if, (i) at least a majority of the Outstanding Voting Units (excluding for this purpose Units held by the General Partner and its Affiliates) approve of such transfer and of the admission of such transferee as general partner, (ii) the transferee agrees to assume the rights and duties of the General Partner and be bound by the provisions of this Agreement and the Operating Company Agreements, (iii) the transferee certifies that it is an Eligible Citizen and (iv) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner or of the Partnership as a member of the Operating Companies or cause the Partnership or the Operating Companies to be taxable as a corporation or otherwise taxed as an entity for federal income tax purposes. The foregoing notwithstanding, the General Partner is expressly permitted to pledge its Partnership Interest as General Partner to secure the obligations of the Partnership under the Revolving Credit Facility, as the same may be amended, supplemented, replaced, refinanced or restated from time to time, or any successor or subsequent loan agreement. (b) Neither Section 11.2(a) nor any other provision of this Agreement shall be construed to prevent (and all Partners do hereby consent to) (i) the transfer by the General Partner of all of its Partnership Interest as a general partner to an Affiliate or (ii) the transfer by the General Partner of all its Partnership Interest as a general partner upon its merger or consolidation with or other combination into any other Person or the transfer by it of all or substantially all of its assets to another Person if, in the case of a transfer described in either clause (i) or (ii) of this sentence, the rights and duties of the General Partner with respect to the 73

Partnership Interest so transferred are assumed by the transferee and the transferee agrees to be bound by the provisions of this Agreement and the Operating Companies Agreement; provided, that in either such case, such transferee certifies that it is an Eligible Citizen, and furnishes to the Partnership an Opinion of Counsel that such merger, consolidation, combination, transfer or assumption will not result in a loss of limited liability of any Limited Partner or of the Partnership as a member of the Operating Companies or cause the Partnership or the Operating Companies to be taxable as a corporation or otherwise taxed as an entity for federal income tax purpose. In the case of a transfer pursuant to this Section 11.2(b), the transferee or successor (as the case may be) shall be admitted to the Partnership as the General Partner immediately prior to the transfer of the Partnership Interest, and the business of the Partnership shall continue without dissolution. 11.3 Transfer of Units. (a) Units may be transferred only in the manner described in Section 10.2. The transfer of any Units and the admission of any new Partner shall not constitute an amendment to this Agreement. (b) Until admitted as a Substituted Limited Partner pursuant to Article XII, the Record Holder of a Unit shall be an Assignee in respect of such Unit. Limited Partners may include custodians, nominees or any other individual or entity in its own or any representative capacity. (c) Each distribution in respect of Units shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holders thereof as of the Record Date set for the distribution. Such payment shall constitute full payment and satisfaction of the Partnership's liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise. (d) A transferee who has completed and delivered a Transfer Application shall be deemed to have (i) requested admission as a Substituted Limited Partner, (ii) agreed to comply with and be bound by and to have executed this Agreement, (iii) represented and warranted that such transferee has the capacity and authority to enter into this Agreement, and that such transferee is an Eligible Citizen, (iv) made the powers of attorney set forth in this Agreement and (v) given the consents and made the waivers contained in this Agreement. 11.4 Restrictions on Transfers. Notwithstanding the other provisions of this Article XI, no transfer of any Common Unit or Preference Unit or interest therein of any Limited Partner or Assignee shall be made if such transfer would (a) violate the then applicable federal or state securities laws or rules and regulations of the Securities and Exchange Commission, any state securities commission or any other governmental authorities with jurisdiction over such transfer, (b) cause the Partnership to be taxable as a corporation or otherwise taxed as an entity for federal income tax purposes or (c) affect the Partnership's existence or qualification as a limited partnership under the Delaware Act. 11.5 Citizenship Certificates; Non-citizen Assignees. 74

(a) At any time and from time to time a Limited Partner or Assignee shall, within thirty days after a written request therefor by the General Partner, furnish to the General Partner, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other status (or, if the Limited Partner or Assignee is a nominee holding for the account of another Person, the nationality, citizenship or other status of such Person) as the General Partner may request. If a Limited Partner or Assignee fails to furnish to the General Partner within the aforementioned 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Units owned by such Limited Partner or Assignee shall be subject to redemption in accordance with the provisions of Section 11.6. In addition, the General Partner may require that the status of any such Limited Partner or Assignee be changed to that of a Non-citizen Assignee, and, thereupon, the General Partner shall be substituted for such Non-citizen Assignee as the Limited Partner in respect of his Units. (b) The General Partner shall in exercising voting rights in respect of Units held by it on behalf of Non-citizen Assignees, distribute the votes in the same ratios as the votes of Limited Partners in respect of Units of the same class other than those of Non-citizen Assignees are cast either for, against or abstaining as to the matter. (c) Upon dissolution of the Partnership, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant to Section 14.4 but shall be entitled to the cash equivalent thereof, and the General Partner shall provide cash in exchange for an assignment of the Non-citizen Assignee's share of the distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the General Partner from the Non-citizen Assignee of his Partnership Interest (representing his right to receive his share of such distribution in kind). (d) At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the General Partner, request admission as a Substituted Limited Partner with respect to any Units of such Non-citizen Assignee not redeemed pursuant to Section 11.6, and, upon the Non-citizen Assignee's admission pursuant to Section 12.2, the General Partner shall cease to be deemed to be the Limited Partner in respect of the Non-citizen Assignee's Units. 11.6 Redemption of Interests. (a) If at any time a Limited Partner or Assignee fails to furnish a Citizenship Certification or other information requested within the 30-day period specified in Section 11.5(a), or if upon receipt of such Citizenship Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the Partnership may, unless the Limited Partner or Assignee establishes to the satisfaction of the General Partner that such Limited Partner or Assignee is an Eligible Citizen or has transferred his Units to a Person who furnishes a Citizenship Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such Limited Partner or Assignee as follows: 75

(i) The General Partner shall not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner or Assignee, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Units, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certification evidencing the Redeemable Units and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner or Assignee would otherwise be entitled in respect of the Redeemable Units will accrue or be made. (ii) The aggregate redemption price for Redeemable Units shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Units of the class to be so redeemed multiplied by the number of Units of each such class included among the Redeemable Units. The redemption price shall be paid in the sole discretion of the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 10% annually and payable in three equal annual installments of principal together with accrued interest commencing one year after the redemption date. (iii) Upon surrender by or on behalf of the Limited Partner or Assignee, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Units, duly endorsed in blank or accompanied by an assignment duly executed in blank, the Limited Partner or Assignee or his duly authorized representative shall be entitled to receive the payment therefor. (iv) After the redemption date, Redeemable Units shall no longer constitute issued and Outstanding Units. (b) The provisions of this Section 11.6 shall also be applicable to Units held by a Limited Partner or Assignee as nominee of a Person determined to be other than an Eligible Citizen. (c) Nothing in this Section 11.6 shall prevent the recipient of a notice of redemption from transferring his Units before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption; provided, the transferee of such Units certifies in the Transfer Application that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date. (d) If the Partnership is or becomes subject to any federal, state or local law or regulation which, in the reasonable determination of the General Partner, provides for the cancellation or forfeiture of any property in which the Partnership or the Operating Companies have an interest, based on the nationality (or other status) of the General Partner, whether or not in its capacity as such, the Partnership may, unless the General Partner has furnished a 76

Citizenship Certification or transferred its Partnership Interest or Units to a Person who furnishes a Citizenship Certification prior to the date fixed for redemption, redeem the Partnership Interest or Interests of the General Partner in the Partnership pursuant to Section 11.6(a), which redemption shall also constitute redemption of the general partner interest of the general partner of the Operating Companies. If such redemption includes a redemption of the Combined Interest, the redemption price thereof shall be equal to the aggregate sum of the Current Market Price (the date of determination for which shall be the date fixed for redemption) of each class of Units then Outstanding in each such case multiplied by the number of Units of such class into which the Combined Interest would then be convertible under the terms of Section 13.3(b) if the General Partner were to withdraw or be removed as the General Partner (the date of determination for which shall be the date fixed for redemption). The redemption price shall be paid in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 10% annually and payable in three equal annual installments of principal, together with accrued interests, commencing one year after the redemption date. ARTICLE XII ADMISSION OF PARTNERS 12.1 Admission of Initial Limited Partners. Upon the issuance by the Partnership of Common Units or Preference Units to the Underwriters as described in Section 4.3(b) and the execution by each such party of a Transfer Application, the General Partner shall admit the Underwriters to the Partnership as Initial Limited Partners in respect of the Units. 12.2 Admission of Substituted Limited Partners. By transfer of a Unit in accordance with Article XI, the transferor shall be deemed to have given the transferee the right to seek admission as a Substituted Limited Partner subject to the conditions of, and in the manner permitted under, this Agreement. A transferor of a Certificate shall, however, only have the authority to convey to a purchaser or other transferee who does not execute and deliver a Transfer Application (i) the right to negotiate such Certificate to a purchaser or other transferee and (ii) the right to transfer the right to request admission as a Substituted Limited Partner to such purchaser or other transferee in respect of the transferred Units. Each transferee of a Unit (including, without limitation, any nominee holder or an agent acquiring such Unit for the account of another Person) who executes and delivers a Transfer Application shall, by virtue of such execution and delivery, be an Assignee and be deemed to have applied to become a Substituted Limited Partner with respect to the Units so transferred to such Person. Such Assignee shall become a Substituted Limited Partner (i) at such time as the General Partner consents thereto, which consent may be given or withheld in the General Partner's sole discretion, and (ii) when any such admission is shown on the books and records of the Partnership. If such consent is withheld such transferee shall be an Assignee. An Assignee shall have an interest in the Partnership equivalent to that of a Limited Partner with respect to allocations and distributions, including, without limitation, liquidating distributions, of the Partnership. With respect to voting rights attributable to Units that are held by Assignees, the General Partner shall be deemed to be the Limited Partner with respect thereto and shall, in exercising the voting rights in respect of such Units on any matter, vote such Units at the written direction of the Assignee who is the Record Holder of such Units. If no such written direction is received, such Units will not be voted. An Assignee shall have no other rights of a Limited Partner. 77

12.3 Admission of Successor General Partner. A successor General Partner approved pursuant to Section 13.1 or 13.2 or the transferee of or successor to all of the General Partner's Partnership Interest pursuant to Section 11.2 who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately prior to the withdrawal or removal of the General Partner pursuant to Section 13.1 or 13.2 or the transfer of the General Partner's Partnership Interest pursuant to Section 11.2; provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Section 11.2 has occurred. Any such successor shall carry on the business of the Partnership without dissolution. In each case, the admission shall be subject to the successor General Partner executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be requited to effect the admission. 12.4 Admission of Additional Limited Partners. (a) A Person (other than the General Partner, an Initial Limited Partner or a Substituted Limited Partner) who makes a Capital Contribution to the Partnership in accordance with this Agreement shall be admitted to the Partnership as an Additional Limited Partner only upon furnishing to the General Partner (i) evidence of acceptance in form satisfactory to the General Partner of all of the terms and conditions of this Agreement, including, without limitation, the power of attorney granted in Section 1.4, (ii) a certification that he is an Eligible Citizen and (iii) such other documents or instruments as may be required in the discretion of the General Partner to effect such Person's admission as an Additional Limited Partner. (b) Notwithstanding anything to the contrary in this Section 12.4, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner's sole discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded on the books and records of the Partnership, following the consent of the General Partner to such admission. 12.5 Amendment of Agreement and Certificate of Limited Partnership. To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Delaware Act to amend the records of the Partnership and if necessary, to prepare as soon as practical an amendment of this Agreement and if required by law, to prepare and file an amendment to the Certificate of Limited Partnership and may for this purpose, among others, exercise the power of attorney granted pursuant to Section 1.4. ARTICLE XIII WITHDRAWAL OR REMOVAL OF PARTNERS 13.1 Withdrawal of the General Partner. 78

(a) The General Partner shall be deemed to have withdrawn from the Partnership upon the occurrence of any one of the following events (each such event herein referred to as an "Event of Withdrawal"): (i) the General partner voluntarily withdraws from the Partnership by giving written notice to the other Partners; (ii) the General Partner transfers all of its rights as general partner pursuant to Section 11.2; (iii) the General Partner is removed pursuant to Section 13.2; (iv) the General Partner (A) makes a general assignment for the benefit of creditors; (B) files a voluntary bankruptcy petition; (C) files a petition or answer seeking for itself a reorganization, arrangement, composition, readjustment liquidation, dissolution or similar relief under any law; (D) files an answer or other pleading admitting or failing to contest the material allegations of a petition filed against the General Partner in a proceeding of the type described in clauses (A) - (C) of this sentence; or (E) seeks, consents to or acquiesces in the appointment of a trustee, receiver or liquidator of the General Partner or of all or any substantial part of its properties; (v) a final and non-appealable judgment is entered by a court with appropriate jurisdiction ruling that the General Partner is bankrupt or insolvent or a final and non-appealable order for relief is entered by a court with appropriate jurisdiction against the General Partner, in each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect; or (vi) a certificate of dissolution or its equivalent is filed for the General Partner, or 90 days expire after the date of notice to the General Partner of revocation of its charter without a reinstatement of its charter, under the laws of its state of incorporation. If an Event of Withdrawal specified in this Section 13.1(a)(iv), (v) or (vi) occurs, the withdrawing General Partner shall give written notice to the Limited Partners within 30 days after such occurrence. The Partners hereby agree that only the Events of Withdrawal described in this Section 13.1 shall result in the withdrawal of the General Partner from the Partnership. (b) Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal will not constitute a breach of this Agreement under the following circumstances: (i) at any time during the period prior to January 1, 2003, the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners; provided, that prior to the effective date of such withdrawal, the withdrawal is approved by at least a majority of the Outstanding Voting Units (excluding for this purpose Units held by the General Partner and its Affiliates) and the General Partner provides to the Partnership an Opinion of Counsel ("Withdrawal Opinion of Counsel") that following the election of a successor General Partner, the General Partner's withdrawal would not result in the loss of limited liability of any Limited Partner or of the Partnership as a member of the Operating Companies or cause the Partnership or any Operating Company to be taxable as a corporation or otherwise taxed as an entity for federal income tax purposes; (ii) at any time after December 31, 79

2002, the General Partner voluntarily withdraws by giving at least 90 days' advance notice to the Limited Partners, such withdrawal to take effect on the date specified in such notice; (iii) at any time that the General Partner ceases to be a General Partner pursuant to Section 13.1(a)(ii) or is removed pursuant to Section 13.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days' advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Voting Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the general partner as a member of the Operating Companies. If the General Partner gives a notice of withdrawal pursuant to Section 13.1(a)(i), holders of at least a majority of such Outstanding Voting Units (excluding for purposes of such determination Units owned by the General Partner and its Affiliates) may, prior to the effective date of such withdrawal, elect a successor General Partner. If, prior to the effective date of the General Partner's withdrawal, a successor is not selected by the Limited Partners as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 14.1. If a successor General Partner is elected and a Withdrawal Opinion of Counsel is rendered such successor shall be admitted (subject to Section 12.3) immediately prior to the effective time of the withdrawal or removal of the Departing Partner and shall continue the business of the Partnership and the Operating Companies without dissolution. 13.2 Removal of the General Partner. The General Partner may be removed with or without Cause if such removal is approved by at least 66?% of the Outstanding Voting Units (excluding for this purpose Units held by the General Partner and its Affiliates). Any such action by such Limited Partners for removal of the General Partner also must provide for the election of a new General Partner by the holders of a majority of the Outstanding Voting Units (excluding for this purpose Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of the successor General Partner pursuant to Article XII. The right of such Limited Partners to remove the General Partner shall not exist or be exercised unless the Partnership has received an Opinion of Counsel opining as to the matters covered by a Withdrawal Opinion of Counsel. Any such successor General Partner shall be subject to the provisions of Section 12.3. 13.3 Interest of Departing Partner and Successor General Partner. (a) In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the Limited Partners under circumstances where Cause does not exist, the Departing Partner shall, at its option exercisable prior to the effective date of the departure of such Departing Partner, promptly receive from its successor in exchange for its Partnership Interest as General Partner an amount in cash equal to the fair market value of the Departing Partner's Partnership Interest as General Partner, such amount to be determined and payable as of the effective date of its departure. If the General Partner withdraws under circumstances where such withdrawal violates this Agreement or if the General Partner is removed by the Limited Partners under circumstances where Cause exists, the General Partner's successor shall have the option described in the immediately preceding sentence, and the Departing Partner shall not have such option. In either 80

case, if the successor acquires the Departing Partner's Partnership Interest as General Partner, such successor General Partner, if requested by the Departing Partner, must also acquire at such time each non-managing interest of such Departing Partner or its Affiliate as a member of the Operating Companies, for an amount in cash equal to the fair market value of such interest determined as of the effective date of its departure. In either case, the Departing Partner shall be entitled to receive all reimbursements due such Departing Partner pursuant to Section 6.4, including, without limitation, any employee-related liabilities (including, without limitation, severance liabilities), incurred in connection with the termination of any employees employed by the General Partner for the benefit of the Partnership or the Operating Companies. Subject to Section 13.3(b), the Departing Partner shall, as of the effective date of its departure, cease to share in any allocations or distributions with respect to its Partnership Interest as the General Partner and Partnership income, gain, loss deduction and credit will be prorated and allocated as set forth in Section 5.2(g). For purposes of this Section 13.3(a), the fair market value of the Departing Partner's Partnership Interest as General Partner and each non-managing interest of such Departing Partner or its Affiliate, as the case may be, as a member of the Operating Companies (collectively, the "Combined Interest") shall be determined by agreement between the Departing Partner and its successor or, failing agreement within 30 days after the effective date of such Departing Partner's departure, by an independent investment banking firm or other independent expert selected by the Departing Partner and its successor, which, in turn, may rely on other experts and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such departure, then the Departing Partner shall designate an independent investment banking firm or other independent expert, the Departing Partner's successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which shall determine the fair market value of the Combined Interest. In making its determination, such independent investment banking firm or other independent expert shall consider the then current trading price of Units on any National Securities Exchange on which Units are then listed the value of the Partnership's assets, the rights and obligations of the General Partner and other factors it may deem relevant. (b) If the Departing Partner's Partnership Interest as General Partner is not acquired in the manner set forth in Section 13.3(a), the Departing Partner and its Affiliate, to the extent applicable, shall become a Limited Partner and their Partnership Interest as General Partner and, at their election, their non-managing interest in the Operating Companies, shall be converted into Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 13.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). For purposes of this Agreement, conversion of the General Partner's Partnership Interest to Units will be characterized as if the General Partner contributed its Partnership Interest to the Partnership in exchange for the newly issued Units. Any successor General Partner shall indemnify the Departing Partner as to all debts and liabilities of the Partnership arising on or after the date on which the Departing Partner becomes a Limited Partner. 81

(c) If the option described in Section 13.3(a) is not exercised by the party entitled to do so, the successor General Partner shall at the effective date of its admission to the Partnership, contribute to the capital of the Partnership cash in an amount such that its Capital Account, after giving effect to such contribution and any adjustments made to the Capital Accounts of all Partners pursuant to Section 4.6(d)(i), shall be equal to one percent (1%) of the Capital Accounts of all Partners. In such event, each successor General Partner shall, subject to the following sentence, be entitled to such percentage interest of all Partnership allocations and distributions and any other allocations and distributions to which the Departing Partner was entitled. In addition, such successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner's admission, the successor General Partner's interest in all Partnership distributions and allocations shall be 1%, and that of the Unitholders shall be 99%. 13.4 Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner's Units becomes a Record Holder, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Units so transferred. ARTICLE XIV DISSOLUTION AND LIQUIDATION 14.1 Dissolution. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the removal or withdrawal of the General Partner, any successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and its affairs should be wound up, upon: (a) the expiration of its term as provide in Section 1.5; (b) an Event of Withdrawal of the General Partner as provided in Section 13.1(a) (subject to Section 14.2) (other than Section 13.1(a)(ii)), unless a successor is elected and an Opinion of Counsel is received as provided in Section 13.1(b) or Section 13.2, as the case may be, and such successor is admitted to the Partnership pursuant to Section 12.3; (c) an election to dissolve the Partnership by the General Partner that is approved by the holders of at least 66?% of the Outstanding Voting Units (and all Limited Partners hereby expressly consent that such approval may be effected upon written consent of the holders of at least 66?% of the Outstanding Voting Units); (d) entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Delaware Act; or (e) the sale of all or substantially all of the assets and properties of the Partnership or all of the Operating Companies, taken as a whole. 14.2 Continuation of the Business of the Partnership after Dissolution. Upon (i) dissolution of the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner and a failure of the requisite number of Partners to appoint a 82

successor General Partner as provided in Section 13.1 or 13.2, as the case may be, then within an additional 90 days or (ii) dissolution of the Partnership upon an event constituting an Event of Withdrawal described in Section 13.1(a)(iv), then within 180 days thereafter, at least 66?% of the Outstanding Voting Units may elect to reconstitute the Partnership and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited partnership on terms identical to those set forth in this Agreement and having as a general partner a Person approved by the holders of at least 66?% of the Outstanding Voting Units. Upon any such election by the holders of at least 66?% of the Outstanding Voting Units, all Partners shall be bound thereby and shall be deemed to have approved thereof. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then: (a) the reconstituted Partnership shall continue until the end of the term set forth in Section 1.5 unless earlier dissolved in accordance with this Article XIV; (b) if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall be treated thenceforth as the interest of a Limited Partner and converted into Units in the manner provided in Section 13.3(b); and (c) all necessary steps shall be taken to cancel this Agreement and the Certificate of Limited Partnership and to enter into and as necessary, to file a new partnership agreement and certificate of limited partnership, and the successor general partner may for this purpose exercise the powers of attorney granted the General Partner pursuant to Section 1.4; provided that the right of at least 66?% of Outstanding Voting Units to approve a successor general partner and to reconstitute and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner and (y) neither the Partnership, the reconstituted limited partnership nor the Operating Companies would become taxable as a corporation or otherwise be taxed as an entity for federal income tax purposes upon the exercise of such right to continue. 14.3 Liquidation. Upon dissolution of the Partnership, unless the Partnership is continued under an election to reconstitute and continue the Partnership pursuant to Section 14.2, the General Partner, or in the event the General Partner has been dissolved or removed, become bankrupt as set forth in Section 13.1 or withdrawn from the Partnership, a liquidator or liquidating committee approved by at least a majority of the Outstanding Voting Units, shall be the Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by at least a majority of the Outstanding Voting Units. The Liquidator shall agree not to resign at any time without 15 days' prior written notice and (if other than the General Partner) may be removed at any time, with or without Cause by notice of removal approved by at least a majority of the Outstanding Voting Units. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by at least a majority of the Outstanding Voting Units. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to 83

refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XIV, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 6.3(b)) to the extent necessary or desirable in the good faith judgment of the Liquidator to carry out the duties and functions of the Liquidator hereunder for and during such period of time as shall be reasonably required in the good faith judgment of the Liquidator to complete the winding up and liquidation of the Partnership as provided for herein. The Liquidator shall liquidate the assets of the Partnership, and apply and distribute the proceeds of such liquidation in the following order of priority, unless otherwise required by mandatory provisions of applicable law: (a) First, the payment to creditors of the Partnership, including, without limitation, Partners who are creditors, in the order of priority provided by law; and the creation of a reserve of cash or other assets of the Partnership for contingent liabilities in an amount if any, determined by the Liquidator to be appropriate for such purposes; and (b) Second, to all Partners in accordance with the positive balances in their respective Capital Accounts after taking into account adjustments to such Capital Accounts pursuant to Section 5.1(d); and (c) Third, to all Partners in accordance with their respective partnership interests. 14.4 Distributions in Kind. (a) Notwithstanding the provisions of Section 14.3, which require the liquidation of the assets of the Partnership, but subject to the order of priorities set forth therein, if prior to or upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership's assets would be impractical or would cause undue loss to the Partners, the Liquidator may, in its absolute discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Partnership (including, without limitation, those to Partners as creditors) or distribute to the Partners, in lieu of cash, as tenants in common add in accordance with the provisions of Section 14.3, undivided interests in such Partnership assets as the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be made only if, in the good faith judgment of the Liquidator, such distributions in kind are in the best interest of the Limited Partners and shall be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreement governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of valuation as it may adopt. (b) In accordance with Section 704(c)(1)(B) of the Code, in the case of any deemed distribution occurring as a result of a termination of the Partnership pursuant to Section 708(b)(1)(B) of the Code, to the maximum extent possible consistent with the priorities of Section 14.3, the General Partner shall have sole discretion to treat the deemed distribution of Partnership assets to Partners as occurring in a manner that will not cause a shift of the Book-Tax 84

Disparity attributable to a Partnership asset existing immediately prior to the deemed distribution to another asset upon the deemed contribution of assets to the reconstituted Partnership, including, without limitation, deeming the distribution of any Partnership assets to be made either to the Partner who contributed such assets or to the transferee of such Partner. 14.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Sections 14.3 and 14.4, the Partnership shall be terminated and the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken. 14.6 Reasonable Time for Winding Up. A reasonable time shall be allowed for the orderly winding up of business and affairs of the Partnership and the liquidation of its assets pursuant to Section 14.3 in order to minimize any losses otherwise attendant upon such winding up, and the provisions of this Agreement shall remain in effect between the Partners during the period of liquidation, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable the Partnership to effectuate. 14.7 Return of Capital. The General Partner shall not be personally liable for the return of the Capital Contributions of the Limited Partners, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets. 14.8 Capital Account Restoration. No Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. 14.9 Waiver of Partition. Each Partner hereby waives any right to partition of the Partnership property.

liability of any Limited Partner or any member of the Operating Companies under applicable law. (e) This Section 15.3 shall only be amended with the approval of the Record Holders of not less than (i) 95% of the Outstanding Voting Units and (ii) 95% of the Outstanding Series B Preference Units voting as a class or series. 15.4 Meetings. All acts of Limited Partners to be taken hereunder shall be taken in the manner provided in this Article XV. Meetings of the Limited Partners may be called only by the General Partner or, with respect to meetings called to remove the General Partner, by Limited Partners owning 66?% or more of the Outstanding Voting Units (excluding for this purpose Units held by the General Partner and its Affiliates). Limited Partners shall call a meeting to remove the General Partner by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a meeting to remove the General Partner. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not more than 60 days after the mailing of notice of the meeting. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business. 15.5 Notice of a Meeting. Notice of a meeting called pursuant to Section 15.4 shall be given to the Record Holders of Voting Units in writing by mail or other means of written communication in accordance with Section 18.1. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of written communication. 15.6 Record Date. For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 15.11, the General Partner may set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed for trading in which case the rule, regulation, guideline or requirement of such exchange shall govern) or (b) in the event that approvals are sought without a meeting the date by which Limited Partners are requested in writing by the General Partner to give such approvals. 15.7 Adjournment. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the 88

adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting a notice of the adjourned meeting shall be given in accordance with this Article XV. 15.8 Waiver of Notice; Approval of Meeting; Approval of Minutes. The transactions of any meeting of Limited Partners, however called and noticed and whenever held shall be as valid as if had at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy, and if, either before or after the meeting, each of the Limited Partners entitled to vote, present in person or by proxy, signs a written waiver of notice or an approval of the holding of the meeting or an approval of the minutes thereof. All waivers and approvals shall be filed with the Partnership records or made a part of the minutes of the meeting. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner disapproves, at the beginning of the meeting, the transaction of any business because the meeting is not lawfully called or convened and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting but not so included in either case if the disapproval is expressly made at the meeting. 15.9 Quorum. The holders of two-thirds of the Outstanding Voting Units of the class for which a meeting has been called represented in person or by proxy shall constitute a quorum at a meeting of Limited Partners of such class unless any such action by the Limited Partners requires approval by holders of a majority in interest of such Voting Units, in which case the quorum shall be a majority (excluding, in each case, if such Voting Units are excluded from such vote, Voting Units held by the General Partner and its affiliates). At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent at least a majority of the Outstanding Voting Units entitled to vote and be present in person or by proxy at such meeting shall be deemed to constitute the act of all Limited Partners, unless a greater or different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Units that in the aggregate represent at least such greater or different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Voting Units specified in this Agreement. In the absence of a quorum, any meeting of Limited Partners may be adjourned from time to by the affirmative vote of a majority of the Outstanding Voting Units represented either in person or by proxy, but no other business may be transacted except as provided in Section 15.7. 15.10 Conduct of Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including, without limitation, the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 15.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting, in either case including, without limitation, a Partner or a director or officer of the General Partner. All minutes shall be kept with the records of the 89

Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including, without limitation, regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the revocation of approvals in writing. 15.11 Action Without a Meeting. Any action that may be taken at a meeting of the Limited Partners may be taken without a meeting if an approval in writing setting forth the action so taken is signed by Limited Partners holding not less than the minimum percentage of the Outstanding Units that would be necessary to authorize to take such action at a meeting at which all the Limited Partners were present and voted. Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partner, the Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) they are deposited with the Partnership in care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are deposited with the Partnership and (c) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners' limited liability, (ii) will not jeopardize the status of the Partnership as a partnership, or cause the Partnership to be taxable as a corporation or otherwise taxed as an entity, under applicable tax laws and regulations and (iii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. 15.12 Voting and Other Rights. (a) Only those Record Holders of Voting Units on the Record Date set pursuant to Section 15.6 shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which holders of the Outstanding Voting Units have the right to vote or to act. All references in this Agreement to votes of, or other acts that may be taken by, the holders of Outstanding Voting Units shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Voting Units. (b) With respect to Voting Units that are held for a Person's account by another Person (such as a broker, dealer, bank trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Voting Units are registered such broker, dealer or other agent shall, in exercising the voting rights in respect of such Voting Units on any matter, and unless the arrangement by two such Persons provides otherwise, vote such Voting Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be 90

entitled to assume it is so acting without further inquiry. The provisions of this Section 15.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 10.4. (c) Except to the extent expressly provided in this Agreement or as expressly required by the Delaware Act, Limited Partners holding Series B Preference Units do not have the right to vote in respect of such Units, either with other holders of Units or as a class or series, with respect to any matter. ARTICLE XVI MERGER 16.1 Authority.

(e) a statement of any amendments or other changes in the constituent documents (the articles or certificate of incorporation, articles of trust, declaration of trust, certificate or agreement of limited partnership or other similar charter or governing document), or the adoption of new constituent documents, in either case as contemplated in Section 17-211(g) of the Delaware Act, of the Surviving Business Entity to be effected by such merger or consolidation; (f) the effective time of the merger, which may be the date of the filing of the certificate of merger pursuant to Section 16.4 or a later date specified in or determinable in accordance with the Merger Agreement; provided that if the effective time of the merger is to be later than the date of the filing of the certificate of merger, it shall be fixed no later than the time of the filing of the certificate of merger and stated therein; and (g) such other provisions with respect to the proposed merger or consolidation as are deemed necessary or appropriate by the General Partner. 16.3 Approval by Limited Partner of Merger or Consolidation. (a) The General Partner of the Partnership, upon its approval of the Merger Agreement, shall direct that the Merger Agreement be submitted to a vote of Limited Partners holding Outstanding Voting Units as of the relevant Record Date whether at a meeting or by written consent, in either case in accordance with the requirements of Article XV. A copy or a summary of the Merger Agreement shall be included in or enclosed with the notice of a meeting or the written consent. (b) The Merger Agreement shall be approved upon receiving the affirmative vote or consent of the holders of at least a majority of the Outstanding Voting Units, unless the Merger Agreement contains any provision as to which, if contained in an amendment to this Agreement, the provisions of this Agreement or the Delaware Act would require the vote or consent of a greater percentage of the Outstanding Voting Units or of any class of Units (voting separately as a class), in which case the vote or consent of such greater percentage or of such class of Units shall be required for approval of the Merger Agreement. (c) After such approval by vote or consent of the Limited Partners, and at any time prior to the filing of the certificate of merger pursuant to Section 16.4, the merger or consolidation may be abandoned pursuant to provisions therefor, if any, set forth in the Merger Agreement. 16.4 Certificate of Merger.

(b) A merger or consolidation effected pursuant to this Article XVI shall not be deemed to result in a transfer or assignment of assets or liabilities from one entity to another having occurred. ARTICLE XVII RIGHT TO ACQUIRE UNITS 17.1 Right to Redeem Preference Units. (a) Notwithstanding anything to the contrary in this Agreement, the Partnership may at any time after the second anniversary of the Conversion Date, in the sole discretion of the General Partner, redeem any or all of the Series A Preference Units then issued and Outstanding for an amount equal to the Unrecovered Capital of such Series A Preference Units plus accrued arrearages, if any, as of the date the General Partner mails the notice described in Section 17.3 of the Partnership's election to redeem such Series A Preference Units. If after giving effect to an anticipated redemption, however, fewer than 1,000,000 Series A Preference Units would be held by Persons other than the General Partner and its Affiliates, the Partnership shall redeem all of such Series A Preference Units if it redeems any Series A Preference Units. (b) Notwithstanding anything to the contrary in this Agreement, the Partnership may at any time after the Series B Preference Unit Issuance Date, in the sole discretion of the General Partner, redeem any or all of the Series B Preference Units for (i) an amount per Series B Preference Unit equal to the Series B Preference Unit Liquidation Value as of the Redemption Date or (ii) a number of Series A Common Units per Series B Preference Unit such that the Current Market Price (as of the third business day immediately preceding the date on which the General Partner mails the notice described in Section 17.3 of the Partnership's election to redeem such Series B Preference Units) of the Series A Common Units issued in respect of each redeemed Series B Preference Unit is equal to the Series B Preference Unit Liquidation Value as of the Redemption Date. (c) With respect to any Series A Common Units issued in redemption or replacement of, or in exchange for, any Series B Preference Units pursuant to Section 17.1(b), the holders of 93

more than 50% of the Outstanding Series A Common Units so issued shall have Demand Registration rights with respect to such Series A Common Units equivalent to such rights granted to the General Partner and its Affiliates under Section 6.14, and Piggyback Registration rights with respect to such Series A Common Units equivalent to such rights granted to the General Partner and its Affiliates under Section 6.14, in each such case until the later to occur of (i) the expiration of the two-year period established by Section 6.14(d) or (ii) two years from such redemption, replacement or exchange date.

Notwithstanding any provision of this Agreement if at any time less than 15% of the total Units of any class then issued and Outstanding are held by Persons other than the General Partner and its Affiliates, the General Partner shall then have the right (which right it may assign and transfer to the Partnership or any Affiliate of the General Partner) exercisable in its sole discretion, to purchase all, but not less than all, of the Units of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the higher of (a) the highest cash price paid by the General Partner or any of its Affiliates for any Unit of such class purchased during the 90 day period preceding the date that the notice described in Section 17.3(b) is mailed or (b) the Current Market Price as of the date five days prior to the date the General Partner (or any of its assignees) mails the Notice of Election to Purchase with respect to its election to purchase such Units.

(a) If the Partnership elects to exercise the right to redeem Series A Preference Units granted pursuant to Section 17.1(a), or the right to redeem Series B Preference Units granted pursuant to Section 17.1(b), the General Partner shall deliver to the Transfer Agent written notice of such election to redeem (the "Notice of Election to Redeem") and shall cause the Transfer Agent to mail a copy of such Notice of Election to Redeem to the Record Holders of such Preference Units (as of a Record Date selected by the General Partner) at least 30, but not more than 60 days prior to the Redemption Date. Such Notice of Election to Redeem also shall be published in daily newspapers of general circulation printed in the English language and published in the Borough of Manhattan, New York. The Notice of Election to Redeem shall specify the date upon which such Preference Units shall be redeemed (the "Redemption Date") and the price (determined in accordance with Section 17.1) at which such Preference Units will be redeemed, and shall state that the Partnership elects to redeem such Preference Units, upon surrender of Unit Certificates representing such Preference Units (or, in the case of Series B Preference Units, such other representation of such Units as the General Partner shall require) in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Preference Units are listed or admitted to trading. Any such Notice of Election to Redeem mailed to a Record Holder of Preference Units at his address as reflected in the records of the Transfer Agent shall be conclusively presumed to have been given whether or not the owner receives such notice. On or prior to the Redemption Date, the General Partner shall deposit with the Transfer Agent cash in an amount sufficient to pay the aggregate redemption price of all of the Preference Units to be redeemed in accordance with this Article XVII. If the Notice of Election to Redeem shall have been duly given as aforesaid at least 30, but not more than 60 days prior to the Redemption Date, and if on or prior to the Redemption Date the deposit described in the preceding sentence has been made for the benefit of the holders of Preference Units subject to redemption as provided herein, then from and after the Redemption Date, notwithstanding that any Unit Certificate shall not have been surrendered for redemption, all rights of the holders of such Preference Units (including, without limitation, any rights pursuant to Article IV, Article V and Article XIV) shall thereupon cease, except the right to receive the redemption price (determined in accordance with Section 17.1) for the Preference Units therefor, without interest, upon surrender to the Transfer Agent of the Unit Certificates representing such Preference Units, and such Preference Units shall be deemed to be no longer Outstanding and each holder of such Preference Units will cease to be a Partner with respect to such Preference Units as of the Redemption Date. (b) If the General Partner, any Affiliate of the General Partner or the Partnership elects to exercise the right to purchase Units granted pursuant to Section 17.2, the General Partner shall deliver to the Transfer Agent written notice of such election to purchase (the "Notice of Election to Purchase") and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Units (as of a Record Date selected by the General Partner) at least 30, but not more than 60 days prior to the Purchase Date. Such Notice of Election to Purchase shall also be published in daily newspapers of general circulation printed in the English language and published in the Borough of Manhattan, New York. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 17.2) at which Units will be purchased and state that the General Partner, its Affiliate or the Partnership, as the case may be, elects to purchase such Units, upon surrender of Unit Certificates representing such Units in exchange for payment at such office or 95

offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which the Units are listed or admitted to trading. Any such Notice of Election to Purchase mailed to a Record Holder of Units at his address as reflected in the records of the Transfer Agent shall be conclusively presumed to have been given whether or not the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent cash in an amount sufficient to pay the aggregate purchase price of all of the Units to be purchased in accordance with Article XVII. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 30 days but not more than 60 days prior to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Units subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Unit Certificate shall not have been surrendered for purchase, all rights of the holders of such Units (including, without limitation, any rights pursuant to Article IV, Article V and Article XIV) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 17.2) for the Units therefor, without interest, upon surrender to the Transfer Agent of the Unit Certificates representing such Units, and such Units shall thereupon be deemed to be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, on the record books of the Transfer Agent and the Partnership, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the owner of all such Units from and after the Purchase Date and shall have all rights as the owner of such Units (including, without limitation, all rights as owner pursuant to Article IV, Article V and Article XIV). 17.4 Surrender of Unit Certificates. At any time from and after the Redemption Date or the Purchase Date, as the case may be, a holder of an Outstanding Unit subject to redemption or purchase as provided in this Article XVII may surrender his Unit Certificate, evidencing such Unit to the Transfer Agent in exchange for payment of the amount described in Section 17.1 or 17.2, as the case may be, therefor without interest thereon.

Any notice to the Partnership shall be deemed given if received by the General Partner at the principal office of the Partnership designated pursuant to Section 1.3.

2.2 CASHLESS SETTLEMENT; CASHLESS CONVERSION. (a) CASHLESS SETTLEMENT. If the Conversion Unit Price with respect to any Conversion Notice is below the Minimum Conversion Price, then the Partnership shall, in lieu of issuing Series A Common Units upon conversion of Series F Convertible Units covered by such Conversion Notice, take one of the following actions (provided, that the election between clauses (i) and (ii) below shall be in the Partnership's sole discretion): (i) pay an amount in cash to such Holder equal to the difference of (x) the product of (A) the number of Series A Common Units issuable on the relevant Conversion Closing Date and (B) the Daily Market Unit Price as of the Business Day immediately preceding the Conversion Notice Date and (y) the Conversion Consideration designated in the relevant Conversion Notice (the "CASH SETTLEMENT AMOUNT"), or (ii) issue to such Holder a number of Series A Common Units equal to the Cash Settlement Amount divided by the Prevailing Unit Price (the "SETTLEMENT UNITS"); provided, that the Holder shall not be required to tender the Conversion Consideration designated in the relevant Conversion Notice (a "CASHLESS SETTLEMENT"). At any time and from time to time with twenty (20) Business Days notice to the Holder, the Partnership shall be entitled to establish a new Minimum Conversion Price (b) CASHLESS CONVERSION ELECTION. If the Prevailing Unit Price is below the Cashless Conversion Trigger Price, a converting Holder may elect in the Conversion Notice to receive Settlement Units, in lieu of the number of Series A Common Units otherwise issuable upon conversion of the Series F Convertible Units covered by such Conversion Notice, provided, that the Holder shall not be required to tender the Conversion Consideration designated in the relevant Conversion Notice (a "CASHLESS CONVERSION"). Notwithstanding the Holder's election to receive Settlement Units in a Cashless Conversion, the Partnership shall have the sole right to elect no later than the Business Day immediately after the date such Conversion Notice is delivered to the Partnership to consummate such Cashless Conversion with the payment of the Cash Settlement Amount in lieu of the issuance of Settlement Units. In addition, if the Prevailing Unit Price is below the Cashless Conversion Trigger Price and the converting Holder does not elect Cashless Conversion in a Conversion Notice, then the Partnership may, no later than the one Business Day immediately after the date such Conversion Notice is delivered to the Partnership, elect Cashless Conversion (and whether the settlement shall be in the form of the Cash Settlement Amount or the Settlement Units). (c) CLOSING OF CASHLESS SETTLEMENT OR CASHLESS CONVERSION. The Partnership shall close a Cashless Settlement or a Cashless Conversion on the Annex A - 9

relevant Conversion Closing Date. The Partnership shall (i) pay the Cash Settlement Amount, if applicable, in immediately available funds by 5:00 p.m., New York City time, on the relevant Conversion Closing Date, to the account specified in the Holder's Conversion Notice, or (ii) issue and deliver the Settlement Units, if applicable, pursuant to Section 2.8(a) on the relevant Conversion Closing Date. Upon receipt of the Cash Settlement Amount or the Settlement Units in connection with any Cashless Settlement or Cashless Conversion, that number of Series F Convertible Units with aggregate Series F1 Conversion Consideration and Series F2 Conversion Consideration equal to the Conversion Consideration designated in the Conversion Notice shall be deemed converted. If the Conversion Consideration deemed to have been tendered pursuant to Section 2.2(a) or 2.2(b) is less than the remaining, unconverted portion of Series F Convertible Units represented by the certificate(s) tendered to the Partnership on the Conversion Closing Date, the Partnership shall issue a replacement certificate(s) as provided in Section 2.8(b). (d) CASHLESS CONVERSIONS INITIATED BY HOLDER. In computing the Cash Settlement Amount or the Settlement Units on a Cashless Conversion initiated by a Holder, in no event shall such computation be based on a number of Series A Common Units in excess of the Maximum Number. Further, in determining whether the Maximum Number has been reached, computation shall be made based on the number of Series A Common Units, if any, actually issued in the case of a Cashless Settlement or a Cashless Conversion, provided, that if a Cashless Conversion is initiated by a Holder, then such computation shall be based on the number of Series A Common Units that would have been issued on the relevant Conversion Closing Date without giving effect to such Cashless Conversion and without regard to whether such Cashless Conversion was settled with Settlement Units, all subject to adjustment by Section 3. Notwithstanding the foregoing, nothing in this Section 2.2(d) shall be construed to change the meaning or the intent of the Statement as originally filed as Annex A to the Partnership Agreement with respect to any provision other than as such may relate to Cashless Conversion or, in the case of Cashless Settlement, as specifically provided in this Section 2.2(d). (e) The Partnership shall, within two (2) Business Days of a Conversion Closing Date pursuant to this Section 2.2, give the Holder written notice if the Partnership is unable to tender the Cash Settlement Amount on such Conversion Closing Date. Within one (1) Business Day after receipt of such notice, Holder shall give the Partnership written notice, at its sole election, of its election to (x) withdraw the Conversion Notice or (y) receive Series A Common Units as determined pursuant to Section 3.1 in lieu of the Cash Settlement Amount, which Conversion Closing Date shall occur within three (3) Business Days of the Partnership's receipt of such Holder's election pursuant to this Section 2.2(e)." 2.3 EXTENSION OF TERM. The Series F1 Expiration Time and the Series F2 Expiration Time, as applicable, shall be extended: Annex A - 10

(a) by one Business Day for each Business Day: (i) that a Blackout Period or a Blackout Violation exists; and (ii) during the period commencing on the earlier of the day on which the Partnership (x) announces a Restatement and (y) announces its intention to make a Restatement and ending on the Restatement Filing Date; and (b) to the extent that the Partnership (x) announces a Restatement or (y) announces its intention to make a Restatement, in either case, within 65 Business Days of the Series F1 Expiration Time or Series F2 Expiration Time, as applicable, to a date that is 65 Business Days after the Restatement Filing Date. Provided, that, if the conditions described in clauses (i) and (ii) of paragraph (a) above both exist on the same Business Day, then the Series F1 Expiration Time or the Series F2 Expiration Time, as applicable, shall be extended by only one Business Day for each Business Day on which these conditions both exist. 2.4 MANNER OF CONVERSION. Subject to and upon compliance with the terms and conditions set forth in this Statement, each Holder shall be entitled to convert each Series F Convertible Unit that such Holder holds, in whole or in part, from time to time, on any Business Day, by receipt by the Partnership of a notice made pursuant to Section 9 in substantially the form of Exhibit B attached to this Statement (or a reasonable facsimile thereof) duly executed by such Holder (a "CONVERSION NOTICE"). The closing of each conversion shall take place at or before 2:00 p.m. New York City time (i) on the third Business Day following and excluding the date the Conversion Notice is received or (ii) on any other date upon which such Holder and the Partnership mutually agree (each, a "CONVERSION CLOSING DATE"). 2.5 CONDITIONS TO CLOSING. (a) HOLDER'S CONDITIONS TO CLOSING. It shall be a condition to each Holder's obligation to close on each Conversion Closing Date that each of the following is satisfied, unless waived by such Holder: (i) the Registration Statement is effective and no stop order has been issued; and (ii) all Series A Common Units to be issued upon such Conversion Closing Date shall be duly listed and admitted to trading on the Principal Securities Exchange upon issuance. (b) THE PARTNERSHIP'S CONDITIONS TO CLOSING. It shall be a condition to the Partnership's obligation to close that each of the following is satisfied, unless waived by the Partnership: Annex A - 11

(i) each Holder shall represent and warrant that each of the following is true and correct as of the Conversion Closing Date: (1) the Holder is a QIB, a large institutional accredited investor, or an insurance company or similar institutional investor whose business is to invest funds entrusted to Holder; (2) the Holder is acquiring the Series A Common Units issuable upon conversion of the Series F Convertible Units for its own account and in the ordinary course of its business and is not participating in a distribution, and has no arrangement or understanding with any Person to participate in the distribution of the Series A Common Units; and (3) the Holder is not a registered "broker" or "dealer" as such terms are defined in Section 3 of the Exchange Act; (ii) there is no Blackout Period in effect; provided that the Partnership has given notice of the commencement of a Blackout Period to each Holder pursuant to Section 9; (iii) the Partnership shall have received from such Holder a completed Citizenship Certification stating the requirements of the Partnership Agreement; and (iv) the issuance of the Series A Common Units shall not cause the Partnership to exceed the Maximum Number. (c) AGREEMENT TO CAUSE CONDITIONS TO BE SATISFIED. The Partnership with respect to Section 2.5(a) and each Holder with respect to Sections 2.5(b)(i) and (iii) shall each use commercially reasonable efforts to cause each of the foregoing conditions to be satisfied at the earliest possible date. (d) REMEDY OF HOLDER. If the conditions set forth in Section 2.5(a) are not satisfied or waived prior to the third Business Day following the date the Conversion Notice is received and no Blackout Period is in effect, then such Holder's exclusive remedies will be those remedies provided in this Section 2.5(d). Upon satisfaction of the condition set forth in the Section 2.5(a), the Partnership shall deliver written notice to such Holder of such satisfaction. If such condition is not satisfied or waived prior to the second Business Day following, and excluding, the Conversion Notice Date, then such Holder may, at its sole option, and at any time: (i) withdraw the Conversion Notice by written notice to the Partnership regardless of whether such condition has been satisfied or waived as of the withdrawal date and, after such withdrawal, shall have no further obligations with respect to such Conversion Notice and may submit a Conversion Notice on any future date with respect to any Annex A - 12

remaining Series A Common Units underlying any such Series F Convertible Units, including those referenced in the original Conversion Notice, or (ii) elect not to withdraw its Conversion Notice, in which case, if no Blackout Period is in effect, the Partnership shall pay such Holder, in immediately available federal funds by 5:00 p.m., New York City time, on the third Business Day following such Holder's delivery to the Partnership of evidence of Holder's payment of the amount described in clause (x) below and certificate(s) representing Series F Convertible Units (including Holder's account information to which such payment should be sent) an amount in cash equal to the lesser of (x) the actual cost that such Holder paid to satisfy its obligations to tender Series A Common Units pursuant to an underlying sales contract for Series A Common Units less the Conversion Consideration such Holder would have tendered on such Conversion Closing Date (or, if the Holder discharged its obligations under such underlying sales contract by making a cash payment, the amount of such cash payment), and (y) the number of Series A Common Units that such Holder would receive on such Conversion Closing Date multiplied by the positive difference, if any, between the Daily Market Unit Price on the relevant Conversion Closing Date and the Conversion Unit Price in effect on the Conversion Notice Date. If the Conversion Consideration deemed to have been tendered pursuant to this Section 2.5(d) is less than the remaining, unconverted portion of Series F Convertible Units represented by the certificate(s) tendered to the Partnership, the Partnership shall issue a replacement certificate(s) as provided in Section 2.8(b). In the case of clause (ii) above, such Holder shall be deemed to have converted a number of Series F Convertible Units with respect to the Conversion Consideration designated in the relevant Conversion Notice, but shall not be required to tender such Conversion Consideration, and the Partnership shall be deemed to have satisfied its obligations with respect to such Conversion Notice. (e) EFFECT OF CLOSING. If any of the conditions contained in this Section 2.5 are not satisfied prior to the Conversion Closing Date, but any Holder and the Partnership consummate the transaction contemplated by the Conversion Notice, then all unsatisfied conditions shall be deemed to have been waived by the relevant party, and neither any Holder nor the Partnership shall have any further rights or remedies with respect to such unsatisfied condition, except any rights and remedies provided under the Securities Act. Notwithstanding the foregoing, Section 2.5(a)(ii) shall not be deemed to have been waived by the Holder unless the Partnership shall have delivered written notice pursuant to Section 9 of the failure to satisfy the condition described in Section 2.5(a)(ii) at least one (1) Business Day before the Conversion Closing Date. Annex A - 13

2.6 WHEN CONVERSION EFFECTIVE. Each conversion under any Series F Convertible Unit shall be deemed to have been effected on the Conversion Closing Date upon receipt of the relevant Conversion Consideration (or deemed to have been received in connection with Deemed Conversions) and surrender of the certificate(s) representing the Series F Convertible Unit(s) (or upon notation on the Transfer Agent's registry if the Series F Convertible Units are in book-entry form), and the Person or Persons in whose name or names any certificate or certificates representing the Series A Common Units shall be issuable upon such conversion as provided in Section 2.7 shall be deemed to have become the holder(s) of record thereof. 2.7 DELIVERY OF SERIES F CONVERTIBLE UNIT AND PAYMENT. On the Conversion Closing Date, a converting Holder shall surrender the certificate(s) representing the Series F Convertible Unit(s) to the Partnership at the address set forth for notices to the Partnership in Section 9 and, except with respect to Deemed Conversions, shall deliver payment: (a) by wire transfer to an account designated by the Partnership on Schedule A of immediately available federal funds in the dollar amount of the Conversion Consideration, (b) by tender of Partnership Bonds with an aggregate principal amount plus accrued interest equal to the dollar amount of the Conversion Consideration (with such documentation and certificates as reasonably requested by the Partnership), or (c) any combination of cash and Partnership Bonds in the dollar amount of the Conversion Consideration.

On the Conversion Closing Date, the Partnership at its expense (including payment by it of any applicable issue taxes) shall cause to be issued in the name of and delivered to a converting Holder or as such Holder may direct, (a) at the election of such Holder, (1) at such address specified by such Holder via reputable overnight courier, one or more certificates for, or (2) via the Depository Trust Company's Deposit and Withdrawal at Custodian (or DWAC) system the number of duly authorized, validly issued, fully paid and non-assessable (except as such non-assessability may be affected by the Delaware Act) Series A Common Units to which such Holder shall be entitled upon such Annex A - 14

ADJUSTMENT OF UNIT PRICES AND SERIES A COMMON UNITS ISSUABLE UPON CONVERSION. 3.1 GENERAL; CONVERSION UNIT PRICE. The number of Series A Common Units which a Holder shall be entitled to receive upon conversion of Series F Convertible Units shall be determined by dividing the Conversion Consideration for such conversion by the Conversion Unit Price in effect for such conversion, all subject to the adjustments, terms and conditions in this Statement. Notwithstanding the foregoing, upon a Cashless Settlement or a Cashless Conversion, the number of Series A Common Units which a Holder shall be entitled to receive upon conversion of Series F Convertible Units shall be as set forth in Section 2.2(a) or 2.2(b), respectively, subject to the adjustments, terms and conditions in this Statement. 3.2 TREATMENT OF PARTNERSHIP INTEREST ADJUSTING EVENTS. In case the Partnership may effect a Partnership Interest Adjusting Event, including a pro rata distribution of Series A Common Units to all holders of Series A Common Units, or a subdivision or combination of the outstanding Series A Common Units, then (a) in the case of any such distribution, immediately after the close of business on the record date for the determination of holders of any class of securities entitled to receive such distribution, or (b) in the case of any such subdivision or combination, at the close of business on the day immediately prior to the day upon which such partnership action becomes effective, the Maximum Number, the Measuring Date Unit Price, and the Conversion Unit Price, the Prevailing Unit Price, the Cashless Conversion Trigger Price and, to the extent applicable, the Daily Market Unit Price and other price or quantity (but excluding the Series F1 Conversion Consideration and the Series F2 Conversion Consideration) in effect immediately prior to such Partnership Interest Adjusting Event shall be proportionately changed.

(i) the effectiveness of such contingent conversion shall be conditional upon the effectiveness of the Business Combination; (ii) such Holder shall have the right to deliver a notice to withdraw such Contingent Conversion Notice until the earlier of (x) the expiration of any election period (if any) pursuant to the Business Combination and (y) the effective date of such Business Combination; provided that if such Business Combination is not consummated within five (5) Business Days of the expiration of such election period, as such may be extended, Holder shall be entitled to withdraw its Contingent Conversion Notice up to the effective date of such Business Combination; and (iii) if such Contingent Conversion Notice shall not have been withdrawn, then on the effective date of such Business Combination, the Holder of such Series F Convertible Units shall receive, upon payment of the Conversion Consideration designated in the Conversion Notice or Delayed Conversion Notice, as the case may be, the same consideration, in the form of cash, securities or other assets (the "ACQUISITION CONSIDERATION") per Series A Common Unit issuable to any other holder of Series A Common Units in connection with such Business Combination based upon the number of Series A Common Units into which such Holder's Series F Convertible Units would be convertible if such Holder had converted each Series F Convertible Unit on the Business Day immediately preceding the date on which such Business Combination occurs. Upon receipt of the Conversion Consideration, such Holder's Series F Convertible Units tendered for conversion pursuant to a Conversion Notice or Contingent Conversion Notice shall be fully converted and shall no longer permit such Holder to convert such Series F Convertible Units into Series A Common Units; provided, that if the Acquisition Consideration is in the form of cash, the Holder shall not be required to tender the relevant Conversion Consideration to convert its Series F Convertible Units, but shall receive an amount in connection with such Business Combination equal to the Acquisition Consideration applicable to such Holder based on the number of Series A Common Units into which such Holder's Series F Convertible Units would be convertible if such Holder had converted each Series F Convertible Unit that it owns on the Business Day immediately preceding the date on which such Business Combination occurs, less such Conversion Consideration. (c) In the case of a Business Combination under clause (i) or (iii) of paragraph (a) above, if the Acquisition Consideration consists solely of cash, (A) the Partnership shall not enter into an agreement with the Acquiring Person resulting in a Business Combination unless such agreement expressly obligates the Acquiring Person to assume the Partnership's obligations under this Section 3.3.(c) and (B) to the extent that any Series F Convertible Unit remains unconverted upon consummation of the Business Combination, the Holder thereof Annex A - 17

shall receive from the Partnership or the Acquiring Person an amount in cash equal to ten percent (10%) multiplied by the Acquisition Consideration resulting from such Business Combination to which such Holder would have been entitled in such Business Combination if such Holder had converted each Series F Convertible Unit held immediately before such Business Combination (the "BUSINESS COMBINATION CASH PAYMENT"); provided, that the Holder shall not under any circumstances be obligated to pay any consideration to convert such Series F Convertible Units in order to receive the cash payment specified in this Section 3.3(c); and, provided, further, that all Business Combination Cash Payments shall be wire transferred to such Holder, in accordance with instructions provided, at the earliest time that consideration is transferred to any other holder of Series A Common Units and, at which time, such Series F Convertible Units shall deemed to be fully converted and, accordingly, the Holder thereof shall have no further conversion rights with respect thereto; or (d) In the case of a Business Combination under clause (i) or (iii) of paragraph (a) above, if the Acquisition Consideration for the Series A Common Units is partially stock or other securities or other non-cash assets and partially cash, then the Partnership shall not enter into an agreement with the Acquiring Person resulting in a Business Combination unless such agreement expressly obligates the Acquiring Person to assume all of the Partnership's obligations under this Section 3.3(d). (x) With respect to the Stock Portion of each unconverted Series F Convertible Unit that would be convertible into Acquisition Consideration in the form of stock or other non-cash assets (the "PARTIAL STOCK ASSUMPTION AGREEMENT") the Holder thereof shall thereafter automatically have equivalent rights with respect to the Acquiring Person and from and after the effective date of the Business Combination and under such Partial Stock Assumption Agreement (A) all references to the Partnership in this Statement shall be references to the Acquiring Person, (B) all references to Series A Common Units in this Statement shall be references to the type of securities for which the Series A Common Units are exchanged in the Business Combination, (C) all references to the Measuring Date Unit Price in this Statement shall be references to the Partial Stock Adjustment Measuring Price, and (D) all references to the Prevailing Unit Price, Cashless Conversion Trigger Price, Daily Market Price and Conversion Unit Price shall be references to such prices with respect to the Acquiring Person and (y) with respect to the Cash Portion of each unconverted Series F Convertible Unit that would have been converted into Acquisition Consideration in the form of cash, the Holder thereof shall be entitled to receive from the Partnership or the Acquiring Person an amount in cash equal to the Business Combination Cash Payment multiplied by the Cash Portion; provided, that the Holder shall not under any circumstances be obligated to pay any consideration to convert any Series F Convertible Unit in order to receive the cash payment specified in this Section 3.3(d); and, provided, further, that all Business Combination Cash Payments shall be wire transferred to such Holder, in accordance with instructions provided, at the earliest time that consideration is transferred to any other holder of Series A Common Units and, at which time, the Cash Portion of each such Series F Convertible Unit shall deemed to be fully Annex A - 18

converted and, accordingly, the Holder thereof shall have no further conversion rights with respect thereto; or (e) In the case of a Business Combination under clause (i) or (iii) of paragraph (a) above, if the Acquisition Consideration for the Series A Common Units consists solely of stock or other non-cash assets of the Acquiring Person, then the Partnership shall not enter into an agreement with the Acquiring Person resulting in a Business Combination unless such agreement expressly obligates the Acquiring Person to assume all of the Partnership's obligations under any unconverted Series F Convertible Units (the "STOCK ASSUMPTION AGREEMENT"). In the event that any Series F Convertible Unit remains unconverted upon consummation of the Business Combination, the Holder thereof shall thereafter automatically have equivalent rights with respect to the Acquiring Person and from and after the effective date of the Business Combination and under such Stock Assumption Agreement (A) all references to the Partnership in this Statement shall be references to the Acquiring Person, (B) all references to Series A Common Units in this Statement shall be references to the securities for which the Series A Common Units are exchanged, (C) all references to the Measuring Date Unit Price in this Statement shall be references to the Stock Adjustment Measuring Price, and (D) all references to the Prevailing Unit Price, Cashless Conversion Trigger Price, Daily Market Price and Conversion Unit Price shall be references to such prices with respect to the Acquiring Person.

All cash payments under this Section 3.3(f) shall be made by wire transfer of immediately available funds to the relevant Holder, in accordance with instructions provided by such Holder no later than the second (2nd) Business Day following the consummation of such Business Combination. Upon receipt of such payment, such Holder's Series F Convertible Annex A - 19

Units shall be deemed to have been fully converted and shall no longer permit such Holder to convert such Series F Convertible Units into Series A Common Units; provided, that unless and until such Holder elects to receive the cash payment set forth in this Section 3.3(f) with respect to each Series F Convertible Unit that such Holder holds, such Series F Convertible Unit shall remain outstanding and may be converted in the manner set forth in Section 2.1. 3.4 NO PROHIBITION FROM ISSUING SERIES A COMMON UNITS. Notwithstanding anything contained in this Statement to the contrary, nothing in this Statement shall prohibit the Partnership from issuing Series A Common Units to any Person, regardless of whether or not such issuance would result in an adjustment under this Section 3. 4. NATURE AND RIGHTS OF SERIES F CONVERTIBLE UNIT. 4.1 NON-VOTING. The Series F Convertible Units shall be non-voting on all matters and no Holder thereof shall be entitled to vote, separately or with all or any series, class or group of Limited Partners, the Series F Convertible Units with respect to any matter (except as set forth in the proviso to this Section 4.1) on which holders of the Series A Common Units are entitled to vote, including, without limitation, mergers, acquisitions, sales of all or substantially all of the Partnership's assets, and similar transactions; provided, that the Partnership shall not, without the affirmative consent of the Holders having a majority-in-interest (based on the unconverted Series F1 Conversion Consideration prior to the vesting of the Series F2 Convertible Units, and on all unconverted Series F Convertible Units after the Series F2 Convertible Units are convertible) as of the date of determination, (i) alter or change the rights, powers or limitations of the Series F Convertible Unit including, without limitation, any changes to the certificate representing the Series F Convertible Unit or the Partnership Agreement that limit any Holder's ability to convert the Series F Convertible Unit under this Statement or affect the enforceability of any Holder's rights under this Statement, (ii) authorize or issue additional Series F Convertible Units or (iii) effect any split or combination of the Series F Convertible Units. 4.2 NO ALLOCATIONS. The Partnership shall not maintain a capital account for any Holder of Series F Convertible Units. Accordingly, the Partnership shall not make any allocations to any Series F Convertible Unit of income, gains, losses or deductions. 4.3 NO DISTRIBUTIONS. The Series F Convertible Units shall not be entitled to receive any distributions, whether regular, special, liquidating or otherwise, of cash, or other assets or securities, but shall be entitled to the adjustments set forth in Section 3.2. 5. REGISTRATION STATEMENT AND BLACKOUT PERIODS. 5.1 The Partnership shall: (a) subject to the Partnership's ability to amend or supplement the Registration Statement or the Prospectus, use its commercially reasonable efforts to keep the Registration Statement effective until the Termination Time; Annex A - 20

(b) prepare and file with the SEC such amendments and supplements to the Registration Statement and the Prospectus as may be necessary to comply with the provisions of the Securities Act with respect to the issuance of Series A Common Units upon conversion of the Series F Convertible Units; (c) cause all Series A Common Units to be listed on each securities exchange and quoted on each quotation service on which similar securities issued by the Partnership are then listed or quoted; (d) provide a transfer agent and registrar for all Series A Common Units and a CUSIP number for all Series A Common Units; and (e) at all times reserve for issuance pursuant to the Registration Statement such number of its Series A Common Units as shall from time to time be sufficient to effect the conversion of all the Series F Convertible Units then outstanding and to satisfy its delivery obligations upon such conversion. 5.2 At any time prior to the Termination Time, the Partnership may, without any liability to the Partnership and upon notice to each Holder pursuant to Section 9, suspend each Holder's rights to convert pursuant to the Registration Statement upon the occurrence of any of the following (each, a "BLACKOUT PERIOD"): (a) a request by the SEC for amendments or supplements to the Registration Statement or the prospectus included therein for additional information; (b) the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (c) the filing of any post-effective amendments or supplements to the Registration Statement or the prospectus included therein that the Partnership deems necessary or appropriate to maintain or utilize for any purpose the Registration Statement or the prospectus included therein; (d) the happening of any event that requires the Partnership to make changes to the Registration Statement or the prospectus included therein in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading; and (e) the Partnership shall deliver to the Holder a certificate signed by any of its Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, General Counsel or Vice President that the Board of Directors of the General Partner has made the determination in good faith and using reasonable judgment that disclosure of information sufficient to ensure that the Registration Statement and related prospectus contain no misstatement or omission would be Annex A - 21

premature, could be reasonably expected to be significantly and materially disadvantageous to the Partnership's financial condition, or could be reasonably expected to be injurious to the consummation of any material transaction. If any of the above conditions or events should occur, the Partnership shall immediately give the Holders written notice that a Blackout Period is in effect; provided that the failure of the Partnership to tender notice of the occurrence of any of the above shall not give rise to any liability in excess of an amount described in Section 5.5. 5.3 Upon the commencement a Blackout Period, the Partnership shall: (a) with respect to any notice pursuant to paragraph (b) of Section 5.2, use commercially reasonable efforts to obtain the withdrawal at the earliest possible time of any order suspending the effectiveness of the Registration Statement; (b) with respect to any notice pursuant to paragraphs (a) or (c) of Section 5.2, as promptly as practical prepare and file a post-effective amendment to the Registration Statement or an amendment or supplement to the prospectus included therein and any other required document so that, as thereafter delivered to Holder upon conversion of the Series F Convertible Unit, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; or (c) with respect to any notice pursuant to paragraphs (d) or (e) of Section 5.2, use commercially reasonable efforts to amend such Registration Statement and/or amend or supplement the prospectus included therein if necessary and to take all other actions necessary to allow the issuance of registered Series A Common Units to take place as promptly as possible, subject, however, to the right of the Partnership in its sole discretion to determine whether to delay further conversion of the Series F Convertible Unit pursuant to the Registration Statement until the conditions or circumstances referred to in the notice have ceased to exist or have been disclosed. 5.4 Upon receipt of notice by the Partnership in accordance with Section 5.1 above that a Blackout Period exists, the Series F Convertible Unit shall immediately become unconvertible until each Holder receives notice from the Partnership that the Blackout Period has ended. Notwithstanding the foregoing, at any time during a Blackout Period, each Holder may: (a) tender a Conversion Notice providing for a Conversion Closing Date delayed to a date that is three Business Days after the termination of the relevant Blackout Period (a "DELAYED CLOSING CONVERSION NOTICE"); each such Delayed Closing Conversion Notice shall have the effect of preserving the Conversion Unit Price, Prevailing Unit Price, and Daily Market Unit Price that was in effect as of the date of such Delayed Closing Conversion Notice, each Annex A - 22

subject to adjustment pursuant to Sections 3 and 5.5; provided, that such Holder may withdraw at any time a Delayed Closing Conversion Notice prior to the relevant delayed Conversion Closing Date; or (b) tender a Conversion Notice requesting the delivery on the Conversion Closing Date of Series A Common Unit that have not been registered pursuant to the Registration Statement, so long as (i) the offer, sale and issuance of the Series A Common Units shall be exempt from the registration requirements of the Securities Act and shall have been registered or qualified (or exempt from registration or qualification) under the registration, permit or qualification requirements of all applicable state securities laws, and (ii) such Holder delivers to the Partnership an opinion from counsel of national repute reasonably satisfactory in the Partnership's sole discretion to such effect. Any certificate(s) representing unregistered Series A Common Units shall be stamped or otherwise imprinted with a legend in the following form (in addition to any legend required under applicable state securities laws): "THE SERIES A COMMON UNITS REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE AND AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO GULFTERRA ENERGY PARTNERS, L.P., SHALL HAVE BEEN FURNISHED TO GULFTERRA ENERGY PARTNERS, L.P." The Partnership shall promptly (a) notify each Holder upon the end of a Blackout Period, and (b) deliver copies of amendments or supplements, if any, to the Registration Statement or the Prospectus. 5.5 The Partnership shall be entitled to exercise its rights to suspend conversion of the Series F Convertible Units as provided in this Section 5 (A) twice in any 12 month period, (B) each such period during which conversion may be suspended at any time shall not exceed 30 days, and (C) no Blackout Period may commence less than 30 days after the end of the preceding Blackout Period; provided, that if any Blackout Period exceeds the duration or frequency limits set forth in clauses (A) and (B) above (a "BLACKOUT VIOLATION"), then the Conversion Unit Price for all unconverted Series F Convertible Units shall be permanently reduced by one and one-half percent (1 1/2%) for each month (or portion thereof) that a Blackout Violation exists. Other than the reduction to the Conversion Unit Price as described in this Section 5.5, the Partnership shall incur Annex A - 23

no liability to any Holder in connection with any Blackout Period or Blackout Violation; provided that notwithstanding the foregoing, the Partnership agrees that the provisions of this Section 5 shall be specifically enforceable. 5.6 If a Blackout Period exists for at least four (4) months, the Holders having a majority-in-interest (based on the unconverted Series F1 Conversion Consideration prior to the vesting of the Series F2 Convertible Units, and on all unconverted Series F Convertible Units after the Series F2 Convertible Units are convertible) as of the date of determination shall be entitled to demand that, to the extent required by the securities laws to permit the issuance of Series A Common Units pursuant to Section 5.4(b), the Partnership withdraw the Registration Statement for a period necessary to effectuate a private placement of the Series A Common Units issuable upon conversion of all or part of the Series F Convertible Units. If so demanded, the Partnership shall withdraw the Registration Statement within 5 Business Days of its receipt of such written demand. Within 60 days of the Partnership's receipt of the written demand of the Holders having a majority-in-interest (based on the unconverted Series F1 Conversion Consideration prior to the vesting of the Series F2 Convertible Units, and on all unconverted Series F Convertible Units after the Series F2 Convertible Units are convertible) as of the date of determination, the Partnership shall prepare and file a replacement registration statement pursuant to which the Series F Convertible Units can be converted and shall thereafter use its commercially reasonable efforts to cause such registration statement to be declared effective as promptly as practicable. Promptly after the issuance of unregistered Series A Common Units, and at its own expense, the Partnership shall file a registration statement under the Securities Act covering the resale of all of the Series A Common Units issued pursuant to the private placement exemption, and shall use commercially reasonable efforts to cause such registration statement to be declared effective; provided, that nothing in this Section 5.6 shall prevent the Partnership from filing a registration statement prior to be requested to do so by any Holders. Upon the withdrawal of the Registration Statement, the percentage described in Section 5.5 shall be reduced to 1% for each month (or portion thereof without duplication for any portion of a month prior to the withdrawal of the Registration Statement) that a Blackout Violation exists after the date on which the Partnership withdraws the Registration Statement. 6. TRANSFERABILITY. 6.1 TRANSFERS OF SERIES F CONVERTIBLE UNITS. The Series F Convertible Units shall not be sold, transferred or otherwise disposed of without the prior written consent of the Partnership, which consent shall be within the sole discretion of the Partnership. Sales, transfers or other dispositions of Series F Convertible Units shall be in increments of one whole unit, and not fractions thereof. The provisions applicable to the Series F Convertible Units shall bind and inure to the benefit of and be enforceable by the Partnership, the respective successors of the Partnership, and by any Holder of Series F Convertible Units. 6.2 PAYMENT OF TAX UPON ISSUE OF TRANSFER. The Partnership shall pay all documentary stamp taxes (if any) attributable to the issuance of Series A Common Units upon the conversion of the Series F Convertible Unit; provided, however, that the Annex A - 24

Partnership shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the registration of any certificates for Series A Common Units in a name other than that of a Holder upon the conversion of Series F Convertible Units, and the Partnership shall not be required to issue or deliver the Series F Convertible Units or certificates for Series A Common Units unless or until the person or persons requesting the issuance thereof shall have paid to the Partnership the amount of such tax or shall have established to the reasonable satisfaction of the Partnership that such tax has been paid. 7. DENIAL OF PREEMPTIVE RIGHTS AND DISSENTERS' RIGHTS. The Series F Convertible Units are not entitled to any preemptive or subscription right in respect of any securities of the Partnership, and do not have dissenters' rights of appraisal. 8. TRANSFER AGENT. Initially, the Partnership (and upon a Business Combination, the Acquiring Person) shall serve as the transfer agent (the "TRANSFER AGENT") for the Series F Convertible Units. The Transfer Agent shall at all times maintain a register (the "UNIT REGISTER") of the Holders of the Series F Convertible Units. The Partnership may deem and treat each Holder of Series F Convertible Units as set forth in the Unit Register as the true and lawful owner thereof for all purposes, and the Partnership shall not be affected by any notice to the contrary. The Partnership may, at any time and from time to time, appoint another Person to serve as the Transfer Agent, and shall upon acceptance by such Person, give notice to each Holder of the change in Transfer Agent. Such new Transfer Agent shall be a (i) Person doing business and in good standing under the laws of the United States or any state thereof, and having a combined capital and surplus of not less than $50,000,000 or (ii) an affiliate of such a Person. The combined capital and surplus of any such new Transfer Agent shall be deemed to be the combined capital and surplus as set forth in the most recent report of its condition published by such Transfer Agent prior to its appointment; provided that such reports are published at least annually pursuant to law or to the requirements of a federal or state supervising or examining authority. After acceptance in writing of such appointment by the new Transfer Agent, it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Transfer Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Partnership and shall be legally and validly executed and delivered by the Partnership. Any Person into which any new Transfer Agent may be merged or any corporation resulting from any consolidation to which any new Transfer Agent shall be a party or any corporation to which any new Transfer Agent transfers substantially all of its corporate trust or shareholders services business shall be a successor Transfer Agent under this Transfer without any further act; provided that such Person (i) would be eligible for appointment as successor to the Transfer Agent under the provisions of this Section 8 or (ii) is a wholly owned subsidiary of the Transfer Agent. Any such successor Transfer Agent shall promptly cause notice of its succession as Transfer Agent to be delivered via reputable overnight courier to the Holders of the Series F Convertible Units at such Holder's last address as shown on the Unit Register.

(d) Whenever, at any time after the Issuing Bank has made payment under any Letter of Credit and has received from any L/C Participant its pro rata share of such payment in accordance with subsection 3.3(a), the Issuing Bank receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by the Issuing Bank), or any payment of interest on account thereof, the Issuing Bank will distribute to such L/C Participant its pro rata share thereof; provided, however, that in the event that any such payment received by the Issuing Bank shall be required to be returned by the Issuing Bank, such L/C Participant shall return to the Issuing Bank the portion thereof previously distributed by the Issuing Bank to it. SECTION 3.4 Fees, Commissions and Other Charges. (a) The Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank, a fronting fee with respect to each Letter of Credit for the period from and including the date of issuance thereof to but not including the Expiry Date thereof, computed at the rate of 0.15% per annum on the average daily amount of the undrawn and unexpired amount of such Letter of Credit. Such fronting fee shall be payable quarterly in advance on the date of issuance of each Letter of Credit and on the last day of each March, June, September and December thereafter, commencing September 30, 2003. Such fee shall be nonrefundable. (b) The Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank and the L/C Participants, a letter of credit commission with respect to each Letter of Credit for the period from and including the date of issuance thereof to but not including the Expiry Date thereof, computed at the rate of the then Applicable Margin for Eurodollar Loans per annum on the average daily amount of the undrawn and unexpired amount of such Letter of Credit. Such commission shall be payable to the L/C Participants to be shared ratably among them in accordance with their respective L/C Commitment Percentages. Such commission shall be payable quarterly in advance on the date of issuance of each Letter of Credit and on the last day of each March, June, September and December thereafter, commencing September 30, 2003. Such fee shall be nonrefundable. (c) In addition to the foregoing fees and commissions, the Borrower shall pay or reimburse the Issuing Bank for such normal and customary costs and expenses as are incurred or charged by the Issuing Bank in issuing, effecting payment under, amending or otherwise administering any Letter of Credit. 33 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(d) The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Bank and the L/C Participants all fees and commissions received by the Administrative Agent for their respective accounts pursuant to this Section 3.4. (e) The fees and commissions described in the preceding paragraphs (a) and (b) shall be based on a 360 day year. If any amounts in the preceding paragraphs (a) and (b) shall be payable on a day that is not a Working Day, such amount shall be extended to the next succeeding Working Day unless the result of such extension would be to carry such amount into another calendar month in which event such amount shall be payable on the immediately preceding Working Day. SECTION 3.5 Reimbursement Obligation of the Borrower. (a) The Borrower agrees to reimburse the Issuing Bank on each date on which the Issuing Bank notifies the Borrower of the date and amount of a draft presented under any Letter of Credit and paid by the Issuing Bank for the amount of (i) such draft so paid and (ii) any taxes, fees, charges or other costs or expenses incurred by the Issuing Bank in connection with such payment. Each such payment shall be made to the Issuing Bank at its address for notices specified herein in lawful money of the United States of America and in immediately available funds. (b) Unless otherwise notified by the Borrower, each drawing under a Letter of Credit shall constitute a request by the Borrower to the Administrative Agent for a borrowing pursuant to Section 2.3 of Revolving Credit Loans which are Alternate Base Rate Loans in the amount of such drawing, subject to satisfaction of the conditions set forth in Section 6.2. The Borrowing Date with respect to such borrowing shall be the date of such drawing. (c) Interest shall be payable on any and all amounts remaining unpaid by the Borrower under this Section 3.5 from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full at the rate which would be payable on any outstanding Revolving Credit Loans which are Alternate Base Rate Loans which were then overdue. SECTION 3.6 Obligations Absolute. (a) The Borrower's obligations under this Article III shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrower may have or have had against the Issuing Bank or any beneficiary of any Letter of Credit. (b) The Borrower also agrees with the Issuing Bank that the Issuing Bank shall not be responsible for, and the Borrower's Reimbursement Obligations under subsection 3.5(a) shall not be affected by, among other things, (i) the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or (ii) any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to 34 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

which such Letter of Credit may be transferred or (iii) any claims whatsoever of the Borrower against any beneficiary of any Letter of Credit or any such transferee. (c) The Issuing Bank shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by the Issuing Bank's gross negligence or willful misconduct. (d) The Borrower agrees that any action taken or omitted by the Issuing Bank under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence of willful misconduct and in accordance with the standards of care specified in the Uniform Commercial Code of the State of New York, shall be binding on the Borrower and shall not result in any liability of the Issuing Bank to the Borrower. SECTION 3.7 Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the Issuing Bank shall promptly notify the Borrower of the date and amount thereof. The responsibility of the Issuing Bank to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit. SECTION 3.8 Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply. ARTICLE IV GENERAL PROVISIONS FOR LOANS SECTION 4.1 Optional and Mandatory Prepayments. (a) The Borrower may on the last day of any Interest Period with respect thereto (or at other times with the payment of applicable breakage costs), in the case of Eurodollar Loans, or at any time and from time to time, in the case of Alternate Base Rate Loans, prepay the Revolving Credit Loans, the Initial Term Loans, the Additional Term Loans of any series, or any combination thereof, in whole or in part, without premium or penalty (except as set forth in Section 4.1(e) below), upon at least four Business Days' irrevocable notice to the Administrative Agent, specifying (i) the date and amount of prepayment, (ii) whether the prepayment is of Eurodollar Loans, Alternate Base Rate Loans or a combination thereof, and, if of a combination thereof, the amount allocable to each, (iii) whether the prepayment is of Revolving Credit Loans, Initial Term Loans, the Additional Term Loans of any series, or any combination thereof, and, if of a combination thereof, the amount allocable to each and (iv) if the prepayment includes Term Loans, the amount allocable, if any, to the Initial Term Loans or the Additional Term Loans of each series. Upon receipt of any such notice the Administrative Agent shall promptly notify each Applicable Lender thereof. If any such notice is given, the 35 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

amount specified in such notice shall be due and payable on the date specified therein, with accrued interest to such date on the amount prepaid in the case of prepayment of Term Loans. Partial prepayments (x) of Revolving Credit Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof and (y) of any Term Loans shall be in an aggregate principal amount of $5,000,000 or a whole multiple thereof. (b) If on any date (including any date on which a certificate of a Responsible Officer of the Borrower is delivered pursuant to subsection 7.2(b)) the sum of the Aggregate Outstanding Revolving Credit Extensions of Credit then outstanding exceeds the then aggregate Revolving Credit Commitments, then, without notice or demand, the Borrower shall promptly prepay the Revolving Credit Loans in an amount equal to such excess. The Borrower may, subject to the terms and conditions of this Agreement, reborrow the amount of any prepayment made under this subsection 4.1(b). (c) The application of any prepayment of Initial Term Loans or Additional Term Loans of any series pursuant to subsection 4.1(a) shall be made to the remaining installments of such Initial Term Loans or Additional Term Loans of such series, as applicable, in the inverse order of their maturity. (d) The application of any prepayment pursuant to subsection 4.1(b) shall be made first to Alternate Base Rate Loans and second to Eurodollar Loans. Each prepayment of the Loans under subsection 4.1(b) (other than Alternate Base Rate Loans) shall be accompanied by accrued interest to the date of such prepayment on the amount prepaid. (e) With respect to any optional prepayment made by the Borrower in connection with the Initial Term Loans on or before the first anniversary of the Initial Term Loan Date, the Borrower shall pay to the Administrative Agent, for the account of the applicable Initial Term Loan Lenders, a prepayment in an amount (including principal and premium) equal to 101% of the aggregate principal amount of the Initial Term Loans to be prepaid as set forth pursuant to the notice of prepayment provided to the Administrative Agent pursuant to Section 4.1(a) above plus all accrued, unpaid interest to the date of such prepayment. SECTION 4.2 Conversion and Continuation Options. (a) The Borrower may elect from time to time to convert Eurodollar Loans to Alternate Base Rate Loans by giving the Administrative Agent at least two Business Days' prior irrevocable notice of such election, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert Alternate Base Rate Loans to Eurodollar Loans by giving the Administrative Agent at least three Working Days' prior irrevocable notice of such election. Any such notice of conversion to Eurodollar Loans shall specify the length of the initial Interest Period or Interest Periods therefor. Upon receipt of any such notice the Administrative Agent shall promptly notify each Applicable Lender thereof. All or any part of outstanding Eurodollar Loans and Alternate Base Rate Loans may be converted as provided herein, provided that (i) no 36 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Loan may be converted into a Eurodollar Loan when any Default or Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined that such a conversion is not appropriate, (ii) any such conversion may only be made if, after giving effect thereto, Section 4.3 shall not have been contravened and (iii) no Loan may be converted into a Eurodollar Loan after the date that is one month prior to the Revolving Credit Termination Date or applicable Term Loan Maturity Date, as applicable. (b) Any Eurodollar Loans may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving notice to the Administrative Agent, in accordance with the applicable provisions of the term "Interest Period" set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan may be continued as such (i) when any Default or Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined that such a continuation is not appropriate, (ii) if, after giving effect thereto, Section 4.3 would be contravened or (iii) after the date that is one month prior to the Revolving Credit Termination Date or applicable Term Loan Maturity Date, as applicable, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to Alternate Base Rate Loans on the last day of such then expiring Interest Period. SECTION 4.3 Minimum Amounts of Tranches. All borrowings, conversions and continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, (a) the aggregate principal amount of the Loans comprising each Tranche shall be equal to $2,000,000 or a whole multiple of $100,000 in excess thereof, and (b) the number of Tranches then outstanding shall not exceed eight. SECTION 4.4 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin. (b) Each Alternate Base Rate Loan shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin. (c) If all or a portion of (i) the principal amount of any Loan, (ii) any interest payable thereon or (iii) any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum which is the higher of (A) the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section 4.4 plus 2% and (B) the Alternate Base Rate plus 1%, in each case from the date of such non-payment until such amount is paid in full (as well after as before judgment). 37 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section 4.4 shall be payable from time to time on demand. (e) With respect to any Initial Term Loan, whether an Alternate Base Rate Loan or a Eurodollar Loan, in the event that, on any date, (i) the Borrower's senior, long-term unsecured debt rating issued by S&P is less than BB+ and (ii) the Borrower's senior, long-term unsecured debt rating issued by Moody's is less than Ba2 or the Borrower's senior secured debt rating issued by Moody's is less than Ba1, then on such date the Applicable Margin with respect to Initial Term Loans that are Alternate Base Rate Loans shall be 3.25% per annum and the Applicable Margin for Initial Term Loans that are Eurodollar Loans shall be 4.50% per annum, which adjustment to the Applicable Margin for Initial Term Loans shall become effective on the date that such event occurs and the increase shall continue until the date upon which (x) the Borrower's senior, long-term unsecured debt rating issued by S&P is equal to or greater than BB+ and (y) the Borrower's senior, long-term unsecured debt rating issued by Moody's is equal to or greater than Ba2 or the Borrower's senior secured debt rating issued by Moody's is equal to or greater than Ba1, on which date the Applicable Margin for Initial Term Loans will return to 2.25% per annum for Alternate Base Rate Loans and 3.50% per annum for Eurodollar Loans. SECTION 4.5 Computation of Interest and Fees. (a) Interest on Alternate Base Rate Loans, commitment fees and interest on overdue interest, commitment fees and other amounts payable hereunder shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. Interest on Eurodollar Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the Alternate Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of the effective date and the amount of each such change in interest rate. (b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to subsection 4.4(a). SECTION 4.6 Inability to Determine Interest Rate. If prior to the first day of any Interest Period: (a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances 38 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or (b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period, the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Alternate Base Rate Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be converted to or continued as Alternate Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the first day of such Interest Period, to Alternate Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans. SECTION 4.7 Pro Rata Treatment and Payments. (a) Each borrowing by the Borrower from the Revolving Credit Lenders hereunder, each payment by the Borrower on account of any commitment fee payable pursuant to Section 2.5 hereunder and any reduction of the Revolving Credit Commitments of the Lenders shall be made pro rata according to the respective Revolving Credit Commitment Percentages of the Revolving Credit Lenders. Each borrowing by the Borrower from the Term Loan Lenders hereunder with respect to the Additional Term Loans of any series shall be made pro rata according to the respective Additional Term Loan Percentages applicable to such Additional Term Loans of such Term Loan Lenders. Each payment (including each prepayment) by the Borrower on account of principal of and interest on (i) the Initial Term Loans or Additional Term Loans of any series shall be made pro rata according to the respective outstanding principal amounts of the Initial Terms Loans or the Additional Term Loans of such series then held by the Term Loan Lenders, or (ii) the Revolving Credit Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Credit Loans then held by the Revolving Credit Lenders. All payments (including prepayments) to be made by the Borrower hereunder and under the Notes, whether on account of principal, interest, fees or otherwise, shall be made without set off or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Administrative Agent's office specified in Section 11.2, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Applicable Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension and with respect to payments of 39 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

fees, such fees accruing during such extension shall be payable on the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Working Day, the maturity thereof shall be extended to the next succeeding Working Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Working Day. (b) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a Borrowing Date that such Lender will not make the amount that would constitute its Applicable Percentage of the borrowing on such date available to the Administrative Agent, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such Borrowing Date, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is made available to the Administrative Agent on a date after such Borrowing Date, such Lender shall pay to the Administrative Agent on demand an amount equal to the product of (i) the daily average Federal Funds Effective Rate during such period, times (ii) the amount of such Lender's Applicable Percentage of such borrowing, times (iii) a fraction the numerator of which is the number of days that elapse from and including such Borrowing Date to the date on which such Lender's Applicable Percentage of such borrowing shall have become immediately available to the Administrative Agent and the denominator of which is 360. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 4.7 shall be conclusive in the absence of manifest error. If such Lender's Applicable Percentage of such borrowing is not in fact made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, the Administrative Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to Alternate Base Rate Loans hereunder, on demand, from the Borrower. SECTION 4.8 Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Alternate Base Rate Loans to Eurodollar Loans shall forthwith be cancelled and (b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Alternate Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 4.11. SECTION 4.9 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: 40 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Note, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for taxes covered by Section 4.10 and changes in the rate of tax on the overall net income of such Lender); (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender which is not otherwise included in the determination of the Eurodollar Rate hereunder; or (iii) shall impose on such Lender any other condition; and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in the Letters of Credit or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section 4.9, it shall promptly notify the Borrower, through the Administrative Agent, of the event by reason of which it has become so entitled. A certificate as to any additional amounts payable pursuant to this Section 4.9 submitted by such Lender, through the Administrative Agent, to the Borrower shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof does or shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder or under any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. SECTION 4.10 Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any 41 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.10) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. (c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 4.10) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. (f) If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 4.10, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 4.10 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental 42 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person. (g) The agreements in this Section 4.10 shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. Each Person that shall become a Lender or a Participant pursuant to Section 11.6 shall, upon the effectiveness of the related transfer, be required to provide all of the forms and statements required pursuant to this Section 4.10, provided that in the case of a Participant such Participant shall furnish all such required forms and statements to the Lender from which the related participation shall have been purchased. SECTION 4.11 Indemnity. The Borrower agrees to indemnify each Lender and to hold each Lender harmless from any loss or expense which such Lender may sustain or incur as a consequence of (a) default by the Borrower in payment when due of the principal amount of or interest on any Eurodollar Loan, (b) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (c) default by the Borrower in making any prepayment after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (d) the making of a prepayment of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto, including, without limitation, in each case, any such loss or expense arising from the reemployment of funds obtained by it or from fees payable to terminate the deposits from which such funds were obtained. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. SECTION 4.12 Lenders Obligation to Mitigate. Each Lender agrees that, as promptly as practicable after it becomes aware that it has been or will be affected by the occurrence of an event or the existence of a condition described under Section 4.8 or subsection 4.9(a) or 4.10(a), it will, to the extent not inconsistent with such Lender's internal policies, use its best efforts (a) to provide written notice to the Borrower describing such condition and the anticipated effect thereof and (b) to make, fund or maintain the affected Eurodollar Loans of such Lender through another lending office of such Lender if as a result thereof the additional moneys which would otherwise be required to be paid in respect of such Loans pursuant to Section 4.8 or subsection 4.9(a) or 4.10(a) would be materially reduced or the illegality or other adverse circumstances which would otherwise require such payment pursuant to Section 4.8 or subsection 4.9(a) or 4.10(a) would cease to exist and if, as determined by such Lender, in its sole discretion, the making, funding or maintaining of such Loans through such other lending office would not otherwise adversely affect such Loans or such Lender. The Borrower hereby agrees to pay all reasonable expenses incurred by any Lender in utilizing another lending office of such Lender pursuant to this Section 4.12. 43 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

SECTION 4.13 Acquisition; Disposition; Redesignation. If the Borrower or any of its Restricted Subsidiaries acquires any Acquired Business or makes any sale or disposition of any assets or property having a value in excess of $20,000,000 permitted by this Agreement or there is a Redesignation of any Subsidiary during any Calculation Period, Consolidated EBITDA, Consolidated Tangible Net Worth, Consolidated Interest Expense, Consolidated Total Senior Indebtedness and Consolidated Total Indebtedness for such Calculation Period will be determined on a pro forma basis as if such Acquired Business were acquired, such assets or property was sold or disposed of or such Redesignation occurred, on the first day thereof. Such pro forma adjustments will be subject to delivery to the Administrative Agent of a certificate of a Responsible Officer of the Borrower. Such certificate may be delivered at any time with respect to any Redesignation and at any time after the last day of the first fiscal quarter of the Borrower to end after the related acquisition date with respect to any Acquired Business or the related disposition date with respect to any such sale or disposition. Each such certificate shall be accompanied by supporting information and calculations with respect to each such Acquired Business, sale or disposition or Redesignation and such other information as any Lender, through the Administrative Agent, may reasonably request. For purposes of determining satisfaction of Section 6.2(c), effect shall be given on the date of determination to pro forma adjustments as described in this Section 4.13 with respect to any Acquired Business that has been acquired as of such date. SECTION 4.14 Redesignated Senior Indebtedness.

After any retiring Administrative Agent's resignation as Administrative Agent, the provisions of this Section shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. SECTION 10.10 Other Agents. None of the Lenders identified on the cover page or the preamble of this Agreement as a "co-syndication agent" or a "co-documentation agent" shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such.

(b) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Collateral Agent or the Issuing Bank and after notice to the Borrower, sell participations to one or more banks or other entities ("Participants") in all or a portion of such Lender's rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Revolving Credit Commitment and the Loans owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Issuing Bank and the Collateral Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents. To the extent permitted by law, each 79 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Participant shall be entitled to the benefits of Section 11.7 as though it were a Lender, provided such Participant agrees to be subject to Section 11.7(a) as though it were a Lender. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 4.9, 4.10 and 4.11 with respect to its participation in the Revolving Credit Commitments, the Loans and the Letters of Credit outstanding from time to time; provided, that no Participant shall be entitled to receive any greater payment pursuant to such Sections than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 4.10 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 4.10(e) as though it were a Lender. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or the other Loan Documents; provided, that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clauses (i) to (v) of the proviso of subsection 11.1(b) to the extent the Participant is directly affected thereby. (c) Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to any Lender, any Affiliate of a Lender or an Approved Fund and, as to any Lender, with the consent of the Borrower and the Administrative Agent (which in each case shall not be unreasonably withheld or, with respect to the Borrower, shall not be required during the continuance of any Event of Default), to one or more additional banks or financial institutions or funds that regularly purchase loans ("Purchasing Lenders") all or any part of its rights and obligations under this Agreement and the Notes pursuant to an Assignment and Acceptance, substantially in the form of Exhibit J, executed by such Purchasing Lender, such transferor Lender (and, in the case of a Purchasing Lender that is not then a Lender, an Approved Fund or an Affiliate of a Lender, by the Borrower and the Administrative Agent except to the extent the Borrower's consent is not required hereunder) and delivered to the Administrative Agent for its acceptance and recording in the Register, provided that (i) no such assignment to an assignee (other than any Lender, an Approved Fund or any Affiliate of any Lender) shall be in an aggregate principal amount of less than $5,000,000, in the case of Revolving Credit Loans, or $1,000,000, in the case of Term Loans (in each case, other than in the case of an assignment of all of a Lender's interest under this Agreement) and (ii) with respect to an assignment involving Revolving Credit Notes, Revolving Credit Loans or Revolving Credit Commitments, the assigning Revolving Credit Lender shall have retained at least $5,000,000 of Revolving Credit Commitments (unless it is assigning all of its Revolving Credit Commitments and Revolving Credit Loans), in each case, unless otherwise agreed by the Borrower and the Administrative Agent and provided, further that this clause shall not be construed to prohibit the assignment or sale of a proportionate part of all the assigning Lender's rights and obligations in respect of one class of Commitments or Loans. For purposes of the proviso contained in the preceding sentence, the amount described therein shall be 80 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

aggregated in respect to each Lender and its related Affiliates, if any. Each Purchasing Lender shall deliver to the Administrative Agent an Administrative Questionnaire prior to the Transfer Effective Date. Upon such execution, delivery, acceptance and recording, from and after the Transfer Effective Date determined pursuant to such Assignment and Acceptance, (x) the Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with a Revolving Credit Commitment, if applicable, as set forth therein, and (y) the transferor Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of a transferor Lender's rights and obligations under this Agreement, such transferor Lender shall cease to be a party hereto but shall continue to be entitled to the benefit of the indemnity and expense reimbursement provisions of the Loan Documents to the extent relating to matters during the time it was a Lender). Such Assignment and Acceptance shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of Total Credit Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and any Note. On or prior to the Transfer Effective Date determined pursuant to such Assignment and Acceptance, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the Note of the transferor Lender a new Revolving Credit Note, Initial Term Loan Note or Additional Term Loan Note, as applicable, to the order of such Purchasing Lender in an amount equal to the Revolving Credit Commitment or Term Loan, as applicable, assumed by it pursuant to such Assignment and Acceptance and, if the transferor Lender has retained Revolving Credit Commitments or Term Loans, as applicable, hereunder, a new Revolving Credit Note, Initial Term Loan Note or Additional Term Loan Note, as applicable, to the order of the transferor Lender in an amount equal to the Revolving Credit Commitment or Term Loans, as applicable, retained by it hereunder. Such new Revolving Credit Notes, Initial Term Loan Notes or Additional Term Loan Notes, as applicable, shall be dated the Restatement Closing Date, Initial Term Loan Date or the date set forth in the applicable Term Loan Addendum, as applicable, and shall otherwise be in the form of the Revolving Credit Note, Initial Term Loan Note or Additional Term Loan Note, as applicable, replaced thereby. The Revolving Credit Notes, Initial Term Loan Note or Additional Term Loan Note, as applicable, surrendered by the transferor Lender shall be returned by the Administrative Agent to the Borrower marked "cancelled." (d) The Administrative Agent, on behalf of the Borrower, shall maintain at its address referred to in Section 11.2 a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the Revolving Credit Commitment, if any, of and principal amount of the Loans, owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Administrative Agent, the Collateral Agent and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Loan recorded therein for all purposes of this Agreement, notwithstanding any notice to the contrary. Any assignment of any Loan or other Obligations hereunder not evidenced by a Note shall be effective only upon appropriate 81 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

entries with respect thereto being made in the Register. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of an Assignment and Acceptance executed by a transferor Lender and Purchasing Lender (and, in the case of a Purchasing Lender that is not then a Lender or an Affiliate thereof, by the Borrower and the Administrative Agent) together with payment to the Administrative Agent of a registration and processing fee of $4,000, the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the Transfer Effective Date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Lenders and the Borrower. (f) The Borrower authorizes each Lender to disclose to any Participant, Purchasing Lender, or counterparty (or its advisor) to any swap, securitization or derivative transaction referencing or involving any of the rights or obligations of such Lender under this Agreement (each, a "Transferee") and any prospective Transferee any and all information in such Lender's possession concerning the Borrower and its Affiliates which has been delivered to such Lender by or on behalf of the Borrower pursuant to this Agreement or which has been delivered to such Lender by or on behalf of the Borrower in connection with such Lender's credit evaluation of the Borrower and its Affiliates prior to becoming a party to this Agreement. (g) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests, including, without limitation, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law without any notice to or consent of the Borrower or the Administrative Agent. SECTION 11.7 Adjustments; Set-off. (a) If any Lender (a "benefitted Lender") shall at any time receive any payment of all or part of its Loans or the Reimbursement Obligations owing to it, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Article IX(i), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender's Loans of the same type or the Reimbursement Obligations owing to it, as the case may be, or interest thereon, such benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender's Loan or the Reimbursement Obligations owing to it, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefitted Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefitted Lender, 82 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. (b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder or under the Notes (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. SECTION 11.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. SECTION 11.9 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. SECTION 11.10 Integration. This Agreement and the other Loan Documents represent the agreement of the Borrower, the Administrative Agent, the Collateral Agent and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent, the Collateral Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents. SECTION 11.11 Usury Savings Clause. It is the intention of the parties hereto to comply with applicable usury laws (now or hereafter enacted); accordingly, notwithstanding any provision to the contrary in this Agreement, the Notes, any of the other Loan Documents or any other document related hereto, in no event shall this Agreement or any such other document require the payment or permit the collection of interest in excess of the maximum amount permitted by such laws. If from any circumstances whatsoever, fulfillment of any provision of this Agreement or of any other document pertaining hereto or thereto, shall involve transcending the limit of validity prescribed by applicable law for the collection or charging of interest, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances the Administrative Agent, the Collateral Agent and the Lenders shall ever receive anything of value as interest or deemed interest by applicable law under this Agreement, the Notes, any of the other Loan Documents or any other document pertaining hereto 83 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

or otherwise an amount that would exceed the highest lawful rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under the Notes or on account of any other indebtedness of the Borrower, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of such indebtedness, such excess shall be refunded to the Borrower. In determining whether or not the interest paid or payable with respect to any indebtedness of the Borrower to the Administrative Agent and the Lenders, under any specified contingency, exceeds the Highest Lawful Rate (as hereinafter defined), the Borrower, the Administrative Agent and the Lenders shall, to the maximum extent permitted by applicable law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate and spread the total amount of interest throughout the full term of such indebtedness so that interest thereon does not exceed the maximum amount permitted by applicable law, and/or (d) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than that permitted by applicable law. To the extent that Section 303.001 et seq., as amended, of the Texas Finance Code is relevant to the Administrative Agent and the Lenders for the purpose of determining the Highest Lawful Rate, the Administrative Agent and the Lenders hereby elect to determine the applicable rate ceiling under such Article by the indicated (weekly) rate ceiling from time to time in effect. Nothing set forth in this Section 11.11 is intended to or shall limit the effect or operation of Section 11.12. In no event shall Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts) apply to this Agreement or the Revolving Credit Notes. For purposes of this Section 11.11, "Highest Lawful Rate" shall mean the maximum rate of nonusurious interest that may be contracted for, charged, taken, reserved or received on the Notes under laws applicable to the Administrative Agent and the Lenders. SECTION 11.12 Governing Law. THIS AGREEMENT AND THE NOTES AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 11.14 Acknowledgements. The Borrower hereby acknowledges that: (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement, the Notes and the other Loan Documents; (b) none of the Administrative Agent, the Collateral Agent nor any Lender has any fiduciary relationship with or duty to the Borrower or any other Loan Party arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent, the Collateral Agent and Lenders, on one hand, and the Borrower and the other Loan Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and (c) no joint venture exists among the Lenders or among the Borrower and the other Loan Parties and the Lenders. SECTION 11.15 Confidentiality. Each of the Administrative Agent, the Collateral Agent and each Lender agrees that it will hold in confidence, any information provided to such Person pursuant to this Agreement; provided, that nothing in this Section 11.15 shall be deemed to prevent the disclosure by the Administrative Agent, the Collateral Agent or any Lender of any such information (a) to any Affiliate of a Lender that has entered into a Hedging Agreement with the Borrower or to any of its or such Affiliate's employees, officers, directors, accountants, attorneys or consultants (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential), (b) to any examiner or other Governmental Authority, (c) that has been or is made public by GTM Energy Company, the Borrower or any of its Subsidiaries or Affiliates or by any third party without breach of this Agreement or that otherwise becomes generally available to the public other than as a result of a disclosure in violation of this Section 11.15, (d) that is or becomes available to any such Person from a third party on a non-confidential basis, (e) that is required to be disclosed by any Requirement of Law, including to any bank examiners or regulatory authorities, (f) that is required to be disclosed by any court, agency, arbitrator or legislative body, or (g) to any Transferee or proposed Transferee; provided, 85 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

further, that notwithstanding anything in this Agreement to the contrary, the Borrower, the Administrative Agent, the Issuing Bank, the Collateral Agent, each Lender and each Related Person may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analysis) that are provided to it relating to such tax treatment and tax structure; and nothing in the foregoing authorization shall apply to any disclosure that would constitute a violation of applicable federal and state securities laws. SECTION 11.16 Waivers of Jury Trial. THE BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT, THE NOTES OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

NOTWITHSTANDING THE FOREGOING, HOWEVER, BORROWER HEREBY AGREES THAT IN CONSIDERATION OF THE CREDIT EXTENDED TO BORROWER UNDER THE LOAN DOCUMENTS AND AS A MATERIAL INDUCEMENT TO THE LENDERS TO ENTER INTO SUCH LOAN DOCUMENTS AND EXTEND SUCH CREDIT TO BORROWER, BORROWER, ON BEHALF OF ITSELF AND ALL OF THE OTHER BORROWER AFFILIATED PARTIES HEREBY RELEASES AND FOREVER DISCHARGES, EACH LENDER, EACH SUBSEQUENT HOLDER OF ANY OF THE NOTES, AND EACH AND ALL OF THEIR PARENT, SUBSIDIARY AND AFFILIATED ENTITIES PAST AND PRESENT, AS WELL AS THEIR RESPECTIVE OWNERS, DIRECTORS, SUCCESSORS, ASSIGNS, AGENTS, OFFICERS, EMPLOYEES, AND REPRESENTATIVES (COLLECTIVELY, THE "RELEASED PARTIES"), OF AND FROM ANY AND ALL CLAIMS WHICH BORROWER AND THE OTHER BORROWER AFFILIATED PARTIES MAY HAVE OR HEREAFTER ACQUIRE AGAINST ANY OR ALL OF THE RELEASED PARTIES BY REASON OF, OR RELATED IN ANY WAY TO, THE PRIOR AGREEMENTS AND ACTIVITIES. SECTION 11.18 Releases. (a) At such time as the Loans, the Reimbursement Obligations and any other obligations under this Agreement shall have been paid in full, the Revolving Credit Commitments have been terminated and no Letters of Credit shall be outstanding, the Collateral shall be released from the Liens created by the Loan Documents, and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent, the Collateral Agent and each Loan Party thereunder and under the other Loan Documents shall terminate, all without delivery of any instrument or 86 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(b) If any of the Collateral shall be sold, transferred or otherwise disposed of by any Loan Party in a transaction permitted by this Agreement or such Loan Party is designated as an Unrestricted Subsidiary in accordance with the terms of this Agreement, then the Lenders authorize the Collateral Agent, at the request and expense of such Loan Party, to execute and deliver to such Loan Party all releases or other documents reasonably necessary or desirable for the release of the Liens created by the applicable Security Documents on such Collateral. At the request and sole expense of the Borrower, the Lenders authorize the Collateral Agent to release a Loan Party from its obligations under the applicable Guarantee and Security Document(s) in the event that all the Capital Stock of such Loan Party shall be sold, transferred or otherwise disposed of in a transaction permitted by this Agreement or such Loan Party becomes a Joint Venture or is designated as an Unrestricted Subsidiary in accordance with the terms of this Agreement, provided that the Borrower shall have delivered to the Collateral Agent, at least five Business Days prior to the date of the proposed release, a written request for release identifying the relevant Loan Party and the terms of the transaction, sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with a certification by the Borrower stating that such transaction is in compliance with this Agreement and the other Loan Documents.

SECTION 12.4 Reliance by Collateral Agent. The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Collateral Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders. 90 SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

SECTION 12.5 Notice of Default. The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Collateral Agent has received notice from the Administrative Agent, a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". The Collateral Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Administrative Agent or the Required Lenders; provided that unless and until the Collateral Agent shall have received such directions, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. SECTION 12.6 Indemnification. The Lenders agree to indemnify the Collateral Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Total Credit Percentages in effect on the date on which indemnification is sought under this Section, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Loans) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Collateral Agent's gross negligence or willful misconduct. The agreements in this Section 12.6 shall survive the payment of the Loans and all other amounts payable hereunder. SECTION 12.7 Successor Collateral Agent. The Collateral Agent may resign as Collateral Agent upon 10 days' written notice to the Lenders. If the Collateral Agent shall resign as Collateral Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the Collateral Agent, and the term "Collateral Agent" shall mean such successor agent effective upon such appointment and approval, and the former Collateral Agent's rights, powers and duties as Collateral Agent shall be terminated, without any other or further act or deed on the part of such former Collateral Agent or any of the parties to this Agreement.

SCHEDULE 5.1 GUARANTEE OBLIGATIONS, CONTINGENT LIABILITIES AND DISPOSITIONS 1. Guarantee Obligations and Contingent Liabilities 1.1 Clawbacks The Borrower is party to a sponsor agreement that constitutes one of the Marco Polo Financing Documents. The Borrower's obligations under such agreement are capped at $22.5 million. The Borrower is party to a sponsor agreement under the Credit Agreement to which Poseidon is party, as amended, restated or otherwise modified through the date of this Agreement, pursuant to which the Borrower guarantees Poseidon's performance of its obligations under its limited liability company agreement. 2.

SCHEDULE 5.6 MATERIAL LITIGATION Grynberg. In 1997, the Borrower (and others) were named defendants in actions brought by Jack Grynberg on behalf of the U.S. Government under the False Claims Act. Generally, these complaints allege an industry-wide conspiracy to underreport the heating value as well as the volumes of the natural gas produced from federal and Native American lands, which deprived the U.S. Government of royalties. The plaintiff in this case seeks royalties that he contends the government should have received had the volume and heating value of natural gas produced from royalty properties been differently measured, analyzed, calculated and reported, together with interest, treble damages, civil penalties, expenses and future injunctive relief to require the defendants to adopt allegedly appropriate gas measurement practices. No monetary relief has been specified in this case. These matters have been consolidated for pretrial purposes (In re: Natural Gas Royalties Qui Tam litigation, U.S. District Court for the District of Wyoming, filed June 1997). In May 2001, the court denied the defendants' motions to dismiss. Discovery is proceeding. Our costs and legal exposure related to these lawsuits and claims are not currently determinable. Will Price (formerly Quinque). The Borrower has also been named a defendant in Quinque Operating Company, et al v. Gas Pipelines and Their Predecessors, et al, filed in 1999 in the District Court of Stevens County, Kansas. Quinque has been dropped as a plaintiff and Will Price has been added. This class action complaint alleges that the defendants mismeasured natural gas volumes and heating content of natural gas on non-federal and non-Native American lands. The plaintiffs in this case seek certification of a nationwide class of natural gas working interest owners and natural gas royalty owners to recover royalties that the plaintiffs contend these owners should have received had the volume and heating value of natural gas produced from their properties been differently measured, analyzed, calculated and reported, together with prejudgment and postjudgment interest, punitive damages, treble damages, attorney's fees, costs and expenses, and future injunctive relief to require the defendants to adopt allegedly appropriate gas measurement practices. No monetary relief has been specified in this case. Plaintiffs' motion for class certification was denied in April 2003. Plaintiffs filed another amended petition to narrow the proposed class to royalty owners in Kansas, Wyoming and Colorado and their motion was granted on July 28, 2003. Our costs and legal exposure related to this lawsuit and claims are not currently determinable. In connection with our April 2002 acquisition of the EPN Holding Company L.P. (now known as GulfTerra Holding V, L.P.) assets, subsidiaries of El Paso Corporation have agreed to indemnify us against all obligations related to existing legal matters at the acquisition date, including the legal matters involving Leapartners, L.P., City of Edinburg, Houston Pipe Line Company LP, and City of Corpus Christi discussed below. During 2000, Leapartners, L.P. filed a suit against El Paso Field Services and others in the District Court of Loving County, Texas, alleging a breach of contract to gather and process natural gas in areas of western Texas related to an asset now owned by GulfTerra Holding III, L.L.C.. In May 2001, the court ruled in favor of Leapartners and entered a judgment against El Paso Field Services of approximately $10 million. El Paso Field Services has filed an appeal with the Eighth Court of Appeals in El Paso, Texas. Briefs have been filed and oral arguments were heard in November 2002. Review by the Court of Appeals is expected in the third quarter of 2003. Schedule 5.6 (Page 1) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Also, GulfTerra Texas Pipeline L.P., (GulfTerra Texas, formerly known as EPGT Texas Pipeline L.P.) now owned by GulfTerra Holding III, L.L.C., is involved in litigation with the City of Edinburg concerning the City's claim that GulfTerra Texas was required to pay pipeline franchise fees under a contract the City had with Rio Grande Valley Gas Company, which was previously owned by GulfTerra Texas and is now owned by Southern Union Gas Company. An adverse judgment against Southern Union and GulfTerra Texas was rendered in Hidalgo County State District court in December 1998 and found a breach of contract, and held both GulfTerra Texas and Southern Union jointly and severally liable to the City for approximately $4.7 million. The judgment relies on the single business enterprise doctrine to impose contractual obligations on GulfTerra Texas and Southern Union's entities that were not parties to the contract with the City. GulfTerra Texas has appealed this case to the Texas Supreme Court seeking reversal of the judgment rendered against GulfTerra Texas. The City seeks a remand to the trial court of its claim of tortious interference against GulfTerra Texas. Briefs have been filed and oral arguments were held in November 2002, and we are awaiting a decision. In December 2000, a 30-inch natural gas pipeline jointly owned by GulfTerra Intrastate, L.P. (GulfTerra Intrastate) now owned by GulfTerra Holding III, L.L.C., and Houston Pipe Line Company LP ruptured in Mont Belvieu, Texas, near Baytown, resulting in substantial property damage and minor physical injury. GulfTerra Intrastate is the operator of the pipeline. Two lawsuits were filed in the state district court in Chambers County, Texas by eight plaintiffs, including two homeowners' insurers. The suits seek recovery for physical pain and suffering, mental anguish, physical impairment, medical expenses, and property damage. Houston Pipe Line Company has been added as an additional defendant. In accordance with the terms of the operating agreement, GulfTerra Intrastate has agreed to assume the defense of and to indemnify Houston Pipe Line Company. As of June 30, 2003, all but one claim has now been settled and these settlements had no impact on our financial statements. The remaining claim relates solely to property damages. The City of Corpus Christi, Texas (the "City") is alleging that GulfTerra Texas and various Coastal entities owe it monies for past obligations under City ordinances that propose to tax GulfTerra Texas on its gross receipts from local natural gas sales for the use of street rights-of-way. No lawsuit has been filed to date. Some but not all of the GulfTerra Texas pipeline at issue has been using the rights-of-way since the 1960's. In addition, the City demands that GulfTerra Texas agree to a going-forward consent agreement in order for the GulfTerra Texas pipeline and Coastal pipeline to have the right to remain in City rights-of-way. In August 2002, we acquired the Big Thicket assets, which consist of the Vidor plant, the Silsbee compressor station and the Big Thicket gathering system located in east Texas, for approximately $11 million from BP America Production Company (BP). Pursuant to the purchase agreement, we have identified environmental conditions that we are working with BP and appropriate regulatory agencies to address. BP has agreed to indemnify us for exposure resulting from activities related to the ownership or operation of these facilities prior to our purchase (i) for a period of three years for non-environmental claims and (ii) until one year following the completion of any environmental remediation for environmental claims. Following expiration of these indemnity periods, we are obligated to indemnify BP for environmental or non-environmental claims. We, along with BP and various other defendants, have been named in Schedule 5.6 (Page 2) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

the following two lawsuits for claims based on activities occuring prior to our purchase of these facilities. Christopher Beverly and Gretchen Beverly, individually and on behalf of the estate of John Beverly v. GulfTerra GC, L.P., et, al. In June 2003, the plaintiffs in this recently filed court action sued us in state district court in Hardin County, Texas. The plaintiffs are the parents of John Christopher Beverly, a two year old child who died on April 15, 2002, allegedly as the result of his exposure to arsenic, benzene and other harmful chemicals in the water supply. Plaintiffs allege that several defendants are responsible for that contamination, including us and BP. Our connection to the occurrences that are the basis for this suit appears to be our August 2002 purchase of certain assets from BP, including a facility in Hardin County, Texas known as the Silsbee compressor station. Under the terms of the indemnity provisions in the Purchase and Sale Agreement between GulfTerra and BP, GulfTerra requested that BP indemnify GulfTerra for any exposure. BP has thus far declined assuming the indemnity obligation. Our costs and legal exposure related to this lawsuit and claims are not currently determinable. Melissa Duvail, et. al., v. GulfTerra GC, L.P., et. al. In June 2003, seventy-four residents of Hardin County, Texas, sued us and others in state district court in Hardin County, Texas. The plaintiffs allege that they have been exposed to hazardous chemicals, including arsenic and benzene, through their water supply, and that the defendants are responsible for that exposure. As with the Beverly case, our connection with the occurrences that are the basis of this suit appears to be our August 2002 purchase of certain assets from BP, including a facility known as the Silsbee compressor station, which is located in Hardin County, Texas. Under the terms of the indemnity provisions in the Purchase and Sale Agreement between us and BP, BP has agreed to indemnify us for this matter.

Agent hereunder as additional collateral security for the Obligations.

If any sums of money or property so paid or distributed in respect of the Collateral shall be received by the Pledgor, the Pledgor shall, until such money or property is paid or delivered to the Collateral Agent, hold such money or property in trust for the Collateral Agent, segregated from other funds of the Pledgor, as additional collateral security for the Obligations. (b) The Pledgor will defend the right, title and interest of the Collateral Agent in and to the Collateral against the claims and demands of all Persons whomsoever. (c) At any time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of the Pledgor, the Pledgor will promptly and duly execute and deliver such further instruments and documents and take such further actions as the Collateral Agent may reasonably request for the purposes of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Lien granted hereby. The Pledgor hereby authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file financing statements and amendments to financing statements that describe the Collateral, in such jurisdictions as the Collateral Agent may deem necessary or desirable in order to perfect or maintain the perfection of the security interests granted by the Pledgor under this Agreement. The Pledgor hereby further authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file continuation statements with respect to previously filed financing statements. If any amount payable under or in connection with any of the Collateral shall be or become evidenced by any promissory note or other instrument, such note or instrument shall be immediately pledged hereunder to the Collateral Agent, duly endorsed in a manner satisfactory to the Collateral Agent. (d) The Pledgor will advise the Collateral Agent promptly, in reasonable detail, of any Lien or claim made or asserted against any of the Collateral other than Liens created hereby and any Lien or claim permitted under the Credit Agreement.

determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

(g) The Pledgor recognizes that financing statements pertaining to the Collateral have been or may be filed where the Pledgor maintains any Collateral or is organized. Without limitation of any other covenant herein, the Pledgor will not cause or permit (i) any change to be made in its name, identity or corporate structure or (ii) any change to the Pledgor's jurisdiction of organization, unless the Pledgor shall have first (1) notified the Collateral Agent of such change at least thirty (30) days prior to the effective date of such change, and (2) taken all action reasonably requested by the Collateral Agent for the purpose of maintaining the perfection and priority of the Collateral Agent's security interests and rights under this Agreement. In any notice furnished pursuant to this subsection, the Pledgor will expressly state that the notice is required by this Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of the Collateral Agent's security interest in the Collateral. 6. CASH DISTRIBUTIONS; CASH DIVIDENDS; VOTING RIGHTS. Unless an Event of Default shall have occurred and be continuing, the Pledgor shall be permitted to receive (a) all cash distributions paid in the normal course of business of the LLCs and to exercise all voting, member and manager rights with respect to the Interests, and (b) all cash dividends paid in the normal course of business of any corporate or other Subsidiary and consistent with past practice, in respect of the Pledged Stock and to exercise all voting and corporate rights with respect to the Pledged Stock; provided, however, that no vote shall be cast or right exercised or other action taken which, in the Collateral Agent's reasonable judgment, would (i) impair the Collateral in a manner that would reasonably be expected to have a Material Adverse Effect or (ii) result in a breach of any provision of the Credit Agreement, the Notes, any other Loan Document or this Agreement. 7. RIGHTS OF THE COLLATERAL AGENT. (a) If an Event of Default shall occur and be continuing, (i) the Collateral Agent shall have the right to receive and shall receive any and all cash distributions or dividends paid in respect of the Collateral and make application thereof to the Obligations in such order as it may determine, and (ii) to the extent permitted by applicable law, all shares or certificates of or evidencing the Interests and the Pledged Stock shall be registered in the name of the Collateral Agent or its nominee, and (whether or not so registered) the Collateral Agent or its nominee may thereafter exercise (A) all voting, corporate, member, manager and other rights pertaining to the Interests or the shares of the Pledged Stock, as the case may be, and (B) any and all rights of conversion, exchange, subscription and any other Exhibit D (Page 8) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

rights, privileges or options pertaining to the Interests or such shares of the Pledged Stock, as the case may be, as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Interests or the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the structure of any of the Subsidiaries, or upon the exercise by the Pledgor or the Collateral Agent of any right, privilege or option pertaining to such shares or certificates of or evidencing the Interests or the Pledged Stock, and in connection therewith, the right to deposit and deliver any and all of the Interests or the Pledged Stock with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. (b) The rights of the Collateral Agent hereunder shall not be conditioned or contingent upon the pursuit by the Collateral Agent of any right or remedy against any Subsidiary, or against any other Person which may be or become liable in respect of all or any part of the Obligations or against any other collateral security therefor, guarantee thereof or right of offset with respect thereto. The Collateral Agent shall not be liable for any failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so, nor shall it be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Pledgor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. 8. COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT. (a) The Pledgor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Pledgor and in the name of the Pledgor or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the Collateral Agent the power and right, on behalf of the Pledgor without notice to or assent by the Pledgor to do the following: (i) upon the occurrence and continuation of an Event of Default to ask, demand, collect, receive and give acceptances and receipts for any and all moneys due and to become due with respect to the Collateral and, in the name of the Pledgor or its own name or otherwise, to take possession of, endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to the Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise as deemed appropriate by the Collateral Agent Exhibit D (Page 9) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

for the purpose of collecting any and all such moneys due with respect to the Collateral or whenever payable; (ii) to pay or discharge taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral; and (iii) upon the occurrence and during the continuance of an Event of Default, (A) to direct any Person liable for any payment to the Pledgor with respect to the Collateral to make payment of any and all moneys due and to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to receive payment of and receipt for any and all moneys, claims and other amounts due and to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, drafts against debtors, assignments, verifications and notices in connection with accounts and other documents relating to the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against the Pledgor with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; and (G) generally, to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and the Pledgor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as the Pledgor might do. The Pledgor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. (b) The powers conferred on the Collateral Agent hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to the Pledgor, any Subsidiary or to any other member or partner of or owner of any limited or general partner interest, limited liability company interest or other equity interest in any Non-Corporate Subsidiary for any act or failure to act. (c) The Pledgor also authorizes the Collateral Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 of this Agreement, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. Exhibit D (Page 10) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

9. REMEDIES. If an Event of Default shall occur and be continuing, the Collateral Agent may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing and to the extent permitted by applicable law, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Pledgor, any of the Subsidiaries or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, in the over-the-counter market, at any exchange, broker's board or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Pledgor, which right or equity is hereby waived or released. The Collateral Agent shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to the Pledgor. To the extent permitted by applicable law, the Pledgor waives all claims, damages and demands it may acquire against the Collateral Agent arising out of the exercise by the Collateral Agent of any of its rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Pledgor shall remain liable for any deficiency if the proceeds of any sale or other disposition of Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any Lender to collect such deficiency. 10. REGISTRATION RIGHTS; PRIVATE SALES. (a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Interests or the Pledged Stock, as the case may be, pursuant to paragraph 9 hereof, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended (the "Securities Act"), the Pledgor will cause the relevant Subsidiaries to (i) execute and deliver, and cause the managers, directors or officers Exhibit D (Page 11) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

of the relevant Subsidiaries to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Interests, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. The Pledgor agrees to cause the relevant Subsidiaries to comply with the provisions of the securities or "Blue Sky" laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. (b) The Pledgor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Interests, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the Collateral Agent than if such sale were a public sale and agrees that such circumstances shall not, in and of themselves, result in a determination that such sale was not made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Interests or the Pledged Stock, as the case may be, for the period of time necessary to permit any of the relevant Subsidiaries to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Subsidiaries would agree to do so. (c) The Pledgor further agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make any sale or sales of all or any portion of the Interests or the Pledged Stock pursuant to this Section valid and binding and in compliance with any and all other applicable Requirements of Law. The Pledgor further agrees that a continuing breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent and the Lenders, that the Collateral Agent and the Lenders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against the Pledgor, and the Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred. 11. LIMITATION ON DUTIES REGARDING COLLATERAL. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in Exhibit D (Page 12) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar securities and property for its own account. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Pledgor or otherwise. 12. POWERS COUPLED WITH AN INTEREST. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 13. SEVERABILITY. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 14. PARAGRAPH HEADINGS. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 15. NO WAIVER; CUMULATIVE REMEDIES; INTEGRATION. The Collateral Agent shall not by any act (except by a written instrument pursuant to this paragraph), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. This Agreement represents the agreement of the Pledgor and the Collateral Agent with respect to the subject matter hereof and there are no promises or representations by the Collateral Agent relative to the subject matter hereof not reflected herein. 16. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING LAW. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Pledgor and the Collateral Agent, provided that any provision of this Agreement that imposes an obligation solely on the Pledgor or provides a right in favor solely of the Collateral Agent may be waived by the Collateral Agent in a letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Agreement shall be binding upon the successors and assigns of the Pledgor and shall inure to the benefit of the Collateral Agent and its successors and assigns.

Collateral Agent for the ratable benefit of the Lenders and the Marco Polo Lenders, segregated from other funds of such Borrower.

All Proceeds constituting collections of Accounts while held by the Collateral Agent (or by any Borrower in trust for the Collateral Agent for the ratable benefit of the Lenders and the Marco Polo Lenders) shall continue to be collateral security for all of the Obligations and shall not constitute payment thereof until applied as hereinafter provided. At such intervals as may be agreed upon by each Borrower and the Collateral Agent, or, if an Event of Default shall have occurred and be continuing, at any time at the Collateral Agent's election, the Collateral Agent shall apply all or any part of the funds on deposit in said special collateral account on account of the Obligations in such order as the Collateral Agent may elect, and any part of such funds which the Collateral Agent elects not so to apply and deems not required as collateral security for the Obligations shall be paid over from time to time by the Collateral Agent to each Borrower or to whomsoever may be lawfully entitled to receive the same. At the Collateral Agent's request, each Borrower shall deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Accounts, including, without limitation, all original orders, invoices and shipping receipts. 4.

No security agreement, financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such as may have been filed in favor of the Collateral Agent, for the ratable benefit of the Lenders and the Marco Polo Lenders, pursuant to this Security Agreement or as may be permitted pursuant to the Credit Agreement.

All actions necessary or desirable to perfect such security interest in each item of Collateral requested by the Collateral Agent have been or will be duly taken. (c) ACCOUNTS.

At any time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of each Borrower, such Borrower will promptly and duly execute and deliver such further instruments and documents and take such further action as the Collateral Agent may reasonably request for the purpose of obtaining or preserving the full benefits of this Security Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Liens created hereby.

Each Borrower hereby further authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file continuation statements with respect to previously filed financing statements.

Upon the request of the Collateral Agent or any of the Lenders, each Borrower shall take or cause to be taken all actions (other than any actions required to be taken by the Collateral Agent or any of the Lenders) necessary to cause the Collateral Agent to have "control" (within the meaning of Sections 9-104, 9-105, 9-106, and 9-107 of the UCC) over any Collateral constituting Deposit Accounts, Electronic Chattel Paper, Investment Property or Letter-of-Credit Rights, and each Borrower shall promptly notify the Collateral Agent and the Lenders of such Borrower's acquisition of any such Collateral. With respect to any goods constituting Collateral that are in the possession of a "bailee" (within the meaning of Section 9-312 of the UCC), such Borrower shall take or cause to be taken all actions (other than any actions required to be taken by the Collateral Agent or any of the Lenders) necessary to cause the Collateral Agent to have a perfected security interest in such Collateral pursuant to the provisions of Section 9-312 of the UCC, and such Borrower shall provide prompt notice to the Collateral Agent and the Lenders of any such Collateral then in the possession of such a "bailee". (b) INDEMNIFICATION.

(c) MAINTENANCE OF RECORDS. The Borrowers will keep and maintain at their own cost and expense satisfactory and complete records of the Collateral, including, without limitation, a record of all payments received and all credits granted with respect to the Accounts. For the Collateral Agent's and the Lenders' further security, the Collateral Agent, for the RATABLE benefit of the Lenders and the Marco Polo Lenders, shall have a security interest in all of the books and records of the Borrowers pertaining to the Collateral, and the Borrowers shall turn over any such books and records to the Collateral Agent or to its representatives during normal business hours at the request of the Collateral Agent. (d) RIGHT OF INSPECTION. The Collateral Agent and the Lenders shall at all times have full and free access during normal business hours to all the books, correspondence and records of each Borrower, and the Collateral Agent and the Lenders and their respective representatives may examine the same, take extracts therefrom and make photocopies thereof, and each Borrower agrees to render to the Collateral Agent and the Lenders, at such Borrower's cost and expense, such clerical and other assistance as may be reasonably requested with regard thereto.

(e) LIMITATION ON LIENS ON COLLATERAL. Each Borrower will not create, incur or permit to exist, will defend the Collateral against, and will take such other action as is necessary to remove, any Lien or claim on or to the Collateral, other than the Liens created hereby and other than as permitted pursuant to the Credit Agreement, and will defend the right, title and interest of the Collateral Agent and the Lenders in and to any of the Collateral against the claims and demands of all Persons whomsoever. (f) LIMITATIONS ON MODIFICATIONS, WAIVERS, EXTENSIONS OF THE AGREEMENTS GIVING RISE TO ACCOUNTS. Except to the extent the same would not reasonably be expected to have a Material Adverse Effect, each Borrower will not (i) except in accordance with the ordinary business practices of the Borrowers, amend, modify, terminate or waive any provision of any Chattel Paper or any agreement giving rise to an Exhibit E (Page 9) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Account or Payment Intangible in any manner which could reasonably be expected to materially adversely affect the value of any Chattel Paper, Payment Intangible or Account as Collateral or (ii) fail to exercise promptly and diligently each and every material right which it may have under any Chattel Paper and each agreement giving rise to an Account or Payment Intangible (other than any right of termination).

(j) CHANGES IN LOCATIONS, NAME, ETC. Each Borrower recognizes that financing statements pertaining to the Collateral have been or may be filed where such Borrower maintains any Collateral or is organized. Without limitation of any other covenant herein, no Borrower will cause or permit (i) any change to be made in its name, identity or corporate structure or (ii) any change to (A) the identity of any warehouseman, common carrier, other third-party transporter, bailee or any agent or processor in possession or control of any Collateral or (B) such Borrower's jurisdiction of organization, unless such Borrower shall have first (1) notified the Collateral Agent and the Lenders of such change at least thirty (30) days prior to the effective date of such change, and (2) taken all action reasonably requested by the Collateral Agent or any of the Lenders for the purpose of maintaining the perfection and priority of the Collateral Agent's security interests under this Security Agreement. In any notice furnished pursuant to this subsection, each Borrower will expressly state that the notice is required by this Security Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of the Collateral Agent's security interest in the Collateral. (k) PATENTS AND TRADEMARKS. Upon request of the Collateral Agent, each Borrower shall execute and deliver any and all agreements, instruments, documents, and papers as the Collateral Agent may request to evidence the Collateral Agent's and the Lender's security interest in any Patent or Trademark and the goodwill and general intangibles of such Borrower relating thereto or represented thereby, and each Borrower hereby constitutes the Collateral Agent its attorney in fact to execute and file all such Exhibit E (Page 10) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT. (a) POWERS. Each of the Borrowers hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Borrower and in the name of such Borrower or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, each of the Borrowers hereby gives the Collateral Agent the power and right, on behalf of such Borrower, without notice to or assent by such Borrower, to do the following: Exhibit E (Page 11) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(i) in the case of any Account, Chattel Paper or Payment Intangible, at any time when the authority of such Borrower to collect the Accounts, Chattel Paper or Payment Intangible has been curtailed or terminated pursuant to the first sentence of Section 3(d) hereof, or in the case of any other Collateral, at any time when any Event of Default shall have occurred and is continuing, in the name of such Borrower or its own name, or otherwise, to take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Account, Instrument, General Intangible, Chattel Paper or Payment Intangible, or with respect to any other Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any Account, Instrument or General Intangible or with respect to any other Collateral whenever payable; (ii) to pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Security Agreement and to pay all or any part of the premiums therefor and the costs thereof; and (iii) upon the occurrence and during the continuance of any Event of Default, (A) to direct any Person liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to ask or demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any thereof and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against such Borrower with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described in clause (E) above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; (G) to assign any Patent or Trademark (along with the goodwill of the business to which any such Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its sole discretion determine; and (H) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and such Borrower's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's and the Lenders' Liens thereon and to effect the intent of this Security Agreement, all as fully and effectively as such Borrower might do. Exhibit E (Page 12) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Each of the Borrowers hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. (b) OTHER POWERS. Each of the Borrowers also authorizes the Collateral Agent and the Lenders, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) NO DUTY ON COLLATERAL AGENT OR LENDERS' PART. The powers conferred on the Collateral Agent and the Lenders hereunder are solely to protect the Collateral Agent's and the Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent or any of the Lenders to exercise any such powers. The Collateral Agent and the Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Borrower for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. 7. PERFORMANCE BY COLLATERAL AGENT OF BORROWERS' OBLIGATIONS. If any Borrower fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Security Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of the Collateral Agent incurred in connection with such performance or compliance, together with interest thereon at a rate per annum 3-1/2% above the Alternate Base Rate, shall be payable by such Borrower to the Collateral Agent on demand and shall constitute Obligations secured hereby. 8. PROCEEDS. In addition to the rights of the Collateral Agent and the Lenders specified in Section 3(d) with respect to payments of Accounts, it is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by each Borrower consisting of cash, checks and other near-cash items shall be held by such Borrower in trust for the Collateral Agent for the ratable benefit of the Lenders and the Marco Polo Lenders, segregated from other funds of such Borrower, and shall, forthwith upon receipt by such Borrower, be turned over to the Collateral Agent in the exact form received by such Borrower (duly indorsed by such Borrower to the Collateral Agent, if required), and (b) any and all such Proceeds received by the Collateral Agent (whether from a Borrower or otherwise) may, in the sole discretion of the Collateral Agent, be held by the Collateral Agent for the ratable benefit of the Lenders and the Marco Polo Lenders as collateral security for, and/or then or at any time thereafter may be applied by the Collateral Agent against, the Obligations (whether matured or unmatured), such application to be in such order as the Collateral Agent shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full and the Commitments shall have been terminated shall be paid over to such Borrower or to whomsoever may be lawfully entitled to receive the same. 9. REMEDIES. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Lenders and the Marco Polo Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a Exhibit E (Page 13) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

secured party under the UCC. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Borrower or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any of the Lenders or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any of the Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Borrower, which right or equity is hereby waived or released. Each Borrower further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Borrower's premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to such Borrower. To the extent permitted by applicable law, each Borrower waives all claims, damages and demands it may acquire against the Collateral Agent or any of the Lenders arising out of the exercise by them of any rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. Each Borrower shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the Lenders to collect such deficiency. 10. LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, any of the Lenders, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Borrower or otherwise. 11. POWERS COUPLED WITH AN INTEREST. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. Exhibit E (Page 14) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

12. SEVERABILITY. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 13. PARAGRAPH HEADINGS. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 14. NO WAIVER; CUMULATIVE REMEDIES. Neither the Collateral Agent nor any of the Lenders shall by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any of the Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any of the Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent or such Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING LAW. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by each of the Borrowers and the Collateral Agent, provided that any provision of this Security Agreement may be waived by the Collateral Agent in a written letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Security Agreement shall be binding upon the successors and assigns of each Borrower and shall inure to the benefit of the Collateral Agent and the Lenders and their respective successors and assigns. This Security Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. 16. NOTICES. Notices hereunder may be given by mail or by facsimile transmission, addressed or transmitted to the Person to which it is being given at such Person's address or transmission number set forth in the Credit Agreement and shall be effective (a) in the case of mail, 3 days after deposit in the postal system, first class postage pre-paid and (b) in the case of facsimile notices, when sent. Each Borrower may change its address and transmission number by written notice to the Collateral Agent, and the Collateral Agent or any of the Lenders may change its address and transmission number by written notice to each Borrower and, in the case of any of the Lenders, to the Collateral Agent. 17. AUTHORITY OF COLLATERAL AGENT. Each Borrower acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any Exhibit E (Page 15) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as among the Collateral Agent, the Lenders and the Marco Polo Lenders be governed by the Credit Agreement, the Marco Polo Financing Documents, and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and each Borrower, the Collateral Agent shall be conclusively presumed to be acting as agent for the Lenders, and the Marco Polo Lenders with full and valid authority so to act or refrain from acting, and no Borrower shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

(b) Each Guarantor agrees that the Obligations may at any time and from time to time exceed the Maximum Guaranteed Amount of such Guarantor or of all of the Guarantors without impairing this Guarantee or affecting the rights and remedies of the Administrative Agent and the Lenders hereunder. (c) No payment or payments made by any Borrower, any of the Guarantors, any other guarantor or any other Person or received or collected by the Administrative Agent or any of the Lenders from any Borrower, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment or payments other than payments made by such Guarantor in respect of the Obligations or payments received or collected from such Guarantor in respect of the Obligations, remain liable for the Obligations up to its Maximum Guaranteed Amount until the Obligations are paid in full and the Commitments are terminated. (d) Each Guarantor agrees that whenever, at any time, or from time to time, it shall make any payment to the Administrative Agent or any of the Lenders on account of Exhibit F (Page 3) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

its liability hereunder, it will notify the Administrative Agent in writing that such payment is made under this Guarantee for such purpose. 3. RIGHT OF CONTRIBUTION. Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor's right of contribution shall be subject to the terms and conditions of Paragraph 5 hereof. The provisions of this Paragraph 3 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall remain liable to the Administrative Agent and the Lenders for the full amount guaranteed by such Guarantor hereunder. 4. RIGHT OF SET-OFF. Each Guarantor hereby irrevocably authorizes the Administrative Agent and each of the Lenders at any time and from time to time without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each Guarantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the Administrative Agent or such Lender to or for the credit or the account of such Guarantor, or any part thereof in such amounts as the Administrative Agent or such Lenders may elect, against and on account of the obligations and liabilities of such Guarantor to the Administrative Agent and the Lenders hereunder and claims of every nature and description of the Administrative Agent and the Lenders against such Guarantor, in any currency, whether arising hereunder, under the Credit Agreement, the Notes, the other Loan Documents or otherwise, as such Lenders may elect, whether or not the Administrative Agent or any of the Lenders has made any demand for payment. Each of the Lenders agrees to notify such Guarantor promptly of any such set-off and the application made by such Lenders or the Administrative Agent, as the case may be, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each of the Lenders and the Administrative Agent under this paragraph are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Lenders may have. 5. NO SUBROGATION. Notwithstanding any payment or payments made by any of the Guarantors hereunder or under any other Loan Document or any set-off or application of funds of any of the Guarantors by any of the Lenders or the Administrative Agent, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any of the Lenders against either of the Borrowers or any other Guarantor or any collateral security or guarantee or right of offset held by any of the Lenders or the Administrative Agent for the payment of the Obligations or any guarantee thereof, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from either of the Borrowers or any other Guarantor in respect of payments made by such Guarantor hereunder or under any other Loan Document, until all amounts owing to the Administrative Agent and the Lenders by the Borrowers on account of the Obligations are paid in full and the Commitments are terminated. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Administrative Agent and the Lenders, segregated from other funds of such Guarantor, Exhibit F (Page 4) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine. 6. AMENDMENTS, ETC. WITH RESPECT TO THE OBLIGATIONS; WAIVER OF RIGHTS. Each Guarantor shall remain obligated hereunder and under the other Loan Documents to which it is a party notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Obligations or any guarantees thereof made by the Administrative Agent or any of the Lenders may be rescinded by such Person and any of the Obligations or any guarantees thereof continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any of the Lenders and the Credit Agreement, the Notes, the other Loan Documents, any other collateral security document or other guarantee or document in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent and/or any of the Lenders may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any of the Lenders for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any of the Lenders shall have any obligation to protect, secure, perfect or insure any Lien at any time held as security for the Obligations or any guarantees thereof or for this Guarantee or any other Loan Document or any property subject thereto. When making any demand hereunder or under any other Loan Document against any of the Guarantors, the Administrative Agent or any of the Lenders may, but shall be under no obligation to, make a similar demand on either of the Borrowers or any other Guarantor or guarantor, and any failure by the Administrative Agent or any of the Lenders to make any such demand or to collect any payments from either of the Borrowers or any such other Guarantor or guarantor or any release of such Borrower or such other Guarantor or guarantor shall not relieve any of the Guarantors in respect of which a demand or collection is not made or any of the Guarantors not so released of their several obligations or liabilities hereunder and under the other Loan Documents, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Administrative Agent or any of the Lenders against any of the Guarantors. For the purposes hereof "demand" shall include the commencement and continuance of any legal proceedings. 7. GUARANTEE ABSOLUTE AND UNCONDITIONAL. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Administrative Agent or any of the Lenders upon this Guarantee or acceptance of this Guarantee or any other Loan Document, the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Guarantee; and all dealings between either of the Borrowers or any of the Guarantors and the Administrative Agent or any of the Lenders shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee and the other Loan Documents. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon either of the Borrowers or any of the Guarantors with respect to the Obligations or any guarantee thereof. Exhibit F (Page 5) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

When pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent and any of the Lenders may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Borrowers or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any of the Lenders to pursue such other rights or remedies or to collect any payments from the Borrowers or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Borrowers or any such other Person or any such collateral security, guarantee or right of offset, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent or any of the Lenders against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Administrative Agent and the Lenders, and their respective successors, indorsees, transferees and assigns, until all the Obligations and the obligations of each Guarantor under this Guarantee shall have been satisfied by payment in full and the Commitments shall be terminated, notwithstanding that from time to time during the term of the Credit Agreement the Borrowers may be free from any Obligations. 8. REINSTATEMENT.

PAYMENTS. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in U.S. Dollars at the office of the Administrative Agent located at One Chase Manhattan Plaza, 8th Floor, New York, New York 10081. 10.

For purposes of this subsection 10(d) "debt" means "liability on a claim", and "claim" means any (x) right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured; or (y) right to an equitable remedy for payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured or unmatured, disputed, undisputed, secured or unsecured.

No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any of the Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any of the Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Administrative Agent or such Lenders would otherwise have on any future occasion.

COVENANTS. Each Pledgor covenants and agrees with the Collateral Agent that, from and after the date of this Agreement until the Obligations are paid in full: (a) If a Pledgor shall, as a result of its ownership of the Collateral, become entitled to receive or shall receive any limited liability company interest, any stock certificate or other certificate (including, without limitation, any certificate representing a stock dividend or distribution in connection with any reclassification, increase or reduction of capital or any certificate issued in connection with any reorganization), option or rights, whether in addition to, in substitution of, as a conversion of, or in exchange for Interests or any shares of the Pledged Stock, or otherwise in respect thereof, such Pledgor shall accept the same as the Collateral Agent's agent, hold the same in trust for the Collateral Agent and deliver the same forthwith to the Collateral Agent in the exact form received, duly indorsed by such Pledgor to the Collateral Agent, if required, together with an undated stock power covering such certificate duly executed in blank and with, if the Collateral Agent so requests, signature guaranteed, to be held by the Collateral Agent hereunder as additional collateral security for the Obligations.

If any sums of money or property so paid or distributed in respect of the Collateral shall be received by any Pledgor, such Pledgor shall, until such money or property is paid or delivered to the Collateral Agent, hold such money or property in trust for the Collateral Agent, segregated from other funds of such Pledgor, as additional collateral security for the Obligations. (b) The Pledgors will defend the right, title and interest of the Collateral Agent in and to the Collateral against the claims and demands of all Persons whomsoever. (c) At any time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of the Pledgors, the Pledgors will promptly and Exhibit G (Page 6) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

duly execute and deliver such further instruments and documents and take such further actions as the Collateral Agent may reasonably request for the purposes of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Lien granted hereby. Each Pledgor hereby authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file financing statements and amendments to financing statements that describe the Collateral, in such jurisdictions as the Collateral Agent may deem necessary or desirable in order to perfect or maintain the perfection of the security interests granted by each Pledgor under this Agreement. Each Pledgor hereby further authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file continuation statements with respect to previously filed financing statements. If any amount payable under or in connection with any of the Collateral shall be or become evidenced by any promissory note or other instrument, such note or instrument shall be immediately pledged hereunder to the Collateral Agent, duly endorsed in a manner satisfactory to the Collateral Agent. (d) The Pledgors will advise the Collateral Agent promptly, in reasonable detail, of any Lien or claim made or asserted against any of the Collateral other than Liens created hereby and any Lien or claim permitted under the Credit Agreement.

(f) Promptly, but in no case later than 30 days after any Pledgor forms (or acquires Capital Stock of) a Subsidiary that is to be a Restricted Subsidiary, such Pledgor shall provide to the Collateral Agent a supplement to this Agreement in the form of Exhibit A hereto, which shall include a schedule supplementing Schedule I, Schedule II, or Schedule III, as the case may be, to pledge its ownership interests in such Restricted Subsidiary to the Collateral Agent. (g) Each Pledgor recognizes that financing statements pertaining to the Collateral have been or may be filed where such Pledgor maintains any Collateral or is organized. Without limitation of any other covenant herein, each Pledgors will not cause or permit (i) any change to be made in its name, identity or corporate structure or (ii) any change to such Pledgor's jurisdiction of organization, unless such Pledgor shall have first (1) notified the Collateral Agent of such change at least thirty (30) days prior to the effective date of such change, and (2) taken all action reasonably requested by the Collateral Agent for the purpose of maintaining the perfection and priority of the Collateral Agent's security interests and rights under this Agreement. In any notice furnished pursuant to this subsection, such Pledgor will expressly state that the notice is required by this Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of the Collateral Agent's security interest in the Collateral. Exhibit G (Page 7) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

6. CASH DISTRIBUTIONS; CASH DIVIDENDS; VOTING RIGHTS. Unless an Event of Default shall have occurred and be continuing, each Pledgor shall be permitted to receive (a) all cash distributions paid in the normal course of business of the LLCs and to exercise all voting, member and manager rights with respect to the Interests, and (b) all cash dividends paid in the normal course of business of any corporate or other Subsidiary and consistent with past practice, in respect of the Pledged Stock and to exercise all voting and corporate rights with respect to the Pledged Stock; provided, however, that no vote shall be cast or right exercised or other action taken which, in the Collateral Agent's reasonable judgment, would (i) impair the Collateral in a manner that would reasonably be expected to have a Material Adverse Effect or (ii) result in a breach of any provision of the Credit Agreement, the Notes, any other Loan Document or this Agreement. 7. RIGHTS OF THE COLLATERAL AGENT. (a) If an Event of Default shall occur and be continuing, (i) the Collateral Agent shall have the right to receive and shall receive any and all cash distributions or dividends paid in respect of the Collateral and make application thereof to the Obligations in such order as it may determine, and (ii) to the extent permitted by applicable law, all shares or certificates of or evidencing the Interests and the Pledged Stock shall be registered in the name of the Collateral Agent or its nominee, and (whether or not so registered) the Collateral Agent or its nominee may thereafter exercise (A) all voting, corporate, member, manager and other rights pertaining to the Interests or the shares of the Pledged Stock, as the case may be, and (B) any and all rights of conversion, exchange, subscription and any other rights, privileges or options pertaining to the Interests or such shares of the Pledged Stock, as the case may be, as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Interests or the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the structure of any of the Subsidiaries, or upon the exercise by any Pledgor or the Collateral Agent of any right, privilege or option pertaining to such shares or certificates of or evidencing the Interests or the Pledged Stock, and in connection therewith, the right to deposit and deliver any and all of the Interests or the Pledged Stock with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. (b) The rights of the Collateral Agent hereunder shall not be conditioned or contingent upon the pursuit by the Collateral Agent of any right or remedy against any Subsidiary, or against any other Person which may be or become liable in respect of all or any part of the Obligations or against any other collateral security therefor, guarantee thereof or right of offset with respect thereto. The Collateral Agent shall not be liable for any failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so, nor shall it be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Pledgor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. Exhibit G (Page 8) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

8. COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT. (a) Each Pledgor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Pledgor and in the name of such Pledgor or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the Collateral Agent the power and right, on behalf of such Pledgor without notice to or assent by such Pledgor to do the following: (i) upon the occurrence and continuation of an Event of Default to ask, demand, collect, receive and give acceptances and receipts for any and all moneys due and to become due with respect to the Collateral and, in the name of such Pledgor or its own name or otherwise, to take possession of, endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to the Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise as deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due with respect to the Collateral or whenever payable; (ii) to pay or discharge taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral; and (iii) upon the occurrence and during the continuance of an Event of Default, (A) to direct any Person liable for any payment to any Pledgor with respect to the Collateral to make payment of any and all moneys due and to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to receive payment of and receipt for any and all moneys, claims and other amounts due and to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, drafts against debtors, assignments, verifications and notices in connection with accounts and other documents relating to the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against any Pledgor with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; and (G) generally, to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and at such Pledgor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's security interest therein, in Exhibit G (Page 9) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

order to effect the intent of this Agreement, all as fully and effectively as the Pledgors might do. Each Pledgor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. (b) The powers conferred on the Collateral Agent hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to any Pledgor, any Subsidiary or to any other member or partner of or owner of any limited or general partner interest, limited liability company interest or other equity interest in any Non-Corporate Subsidiary for any act or failure to act. (c) Each Pledgor also authorizes the Collateral Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 of this Agreement, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. 9. REMEDIES. If an Event of Default shall occur and be continuing, the Collateral Agent may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing and to the extent permitted by applicable law, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Pledgor, any of the Subsidiaries or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, in the over the counter market, at any exchange, broker's board or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Pledgor, which right or equity is hereby waived or released. The Collateral Agent shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to any Pledgor. To the extent Exhibit G (Page 10) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

permitted by applicable law, each Pledgor waives all claims, damages and demands it may acquire against the Collateral Agent arising out of the exercise by the Collateral Agent of any of its rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Pledgors shall remain liable for any deficiency if the proceeds of any sale or other disposition of Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the Lenders to collect such deficiency. 10. REGISTRATION RIGHTS; PRIVATE SALES. (a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Interests or the Pledged Stock, as the case may be, pursuant to paragraph 9 hereof, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended (the "SECURITIES ACT"), each Pledgor will cause the relevant Subsidiaries to (i) execute and deliver, and cause the managers, directors or officers of the relevant Subsidiaries to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Interests, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Pledgor agrees to cause the relevant Subsidiaries to comply with the provisions of the securities or "Blue Sky" laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. (b) Each Pledgor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Interests, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the Collateral Agent than if such sale were a public sale and agrees that such circumstances shall not, in and of themselves, result in a determination that such sale was not made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Interests or the Pledged Stock, as the case may be, for the period of time necessary to permit any of the relevant Subsidiaries to Exhibit G (Page 11) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Subsidiaries would agree to do so. (c) Each Pledgor further agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make any sale or sales of all or any portion of the Interests or the Pledged Stock pursuant to this Section valid and binding and in compliance with any and all other applicable Requirements of Law. Each Pledgor further agrees that a continuing breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent and the Lenders, that the Collateral Agent and the Lenders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against any Pledgor, and each Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred. 11. LIMITATION ON DUTIES REGARDING COLLATERAL. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar securities and property for its own account. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Pledgor or otherwise. 12. POWERS COUPLED WITH AN INTEREST. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 13. SEVERABILITY. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 14. PARAGRAPH HEADINGS. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 15. NO WAIVER; CUMULATIVE REMEDIES; INTEGRATION. The Collateral Agent shall not by any act (except by a written instrument pursuant to this paragraph), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any future occasion. The rights and Exhibit G (Page 12) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. This Agreement represents the agreement of the Pledgors and the Collateral Agent with respect to the subject matter hereof and there are no promises or representations by the Collateral Agent relative to the subject matter hereof not reflected herein. 16. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING LAW. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by each of the Pledgors and the Collateral Agent, provided that any provision of this Agreement that imposes an obligation solely on a Pledgor or provides a right in favor solely of the Collateral Agent may be waived by the Collateral Agent in a letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Agreement shall be binding upon the successors and assigns of the Pledgors and shall inure to the benefit of the Collateral Agent and its successors and assigns. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 17. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF MAY BE BROUGHT AGAINST IT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PLEDGOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH PLEDGOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO EACH PLEDGOR AT THE ADDRESS SET FORTH FOR GTM IN THE CREDIT AGREEMENT. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE COLLATERAL AGENT OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY PLEDGOR IN ANY OTHER JURISDICTION. 18. WAIVERS. (a) EACH PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY ACTION DESCRIBED IN PARAGRAPH 17, OR THAT SUCH PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT, AND AGREES NOT TO PLEAD OR CLAIM THE SAME. Exhibit G (Page 13) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

(b) EACH OF THE PLEDGORS AND THE COLLATERAL AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OR COUNTERCLAIM OF ANY TYPE AS TO ANY MATTER ARISING DIRECTLY OR INDIRECTLY OUT OF OR WITH RESPECT TO THIS AGREEMENT. 19. NOTICES. All notices, requests and demands to or upon the Collateral Agent, the Pledgors or the Subsidiaries to be effective shall be in writing (including by facsimile transmission), and, unless otherwise expressly provided herein, shall be deemed to have been given or made when actually delivered or, in the case of notice by facsimile transmission, when received, addressed as set forth in the Credit Agreement, in the case of the Pledgors and the Collateral Agent, or as set forth under such party's signature below, in the case of the Subsidiaries. The Pledgors and the Subsidiaries may change their respective addresses and transmission numbers by written notice to the Collateral Agent. 20. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO SUBSIDIARIES.

Any balance of such Proceeds remaining after Exhibit H (Page 13) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

the Obligations shall have been paid in full and the Commitments shall have been terminated shall be paid over to such Grantor or to whomsoever may be lawfully entitled to receive the same. 9. REMEDIES. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Lenders and the Marco Polo Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any of the Lenders or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any of the Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived or released. Each Grantor further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor's premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to such Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any of the Lenders arising out of the exercise by them of any rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the Lenders to collect such deficiency. 10. LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it Exhibit H (Page 14) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, any of the Lenders, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or otherwise. 11. POWERS COUPLED WITH AN INTEREST. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 12. SEVERABILITY. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 13. PARAGRAPH HEADINGS. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 14. NO WAIVER; CUMULATIVE REMEDIES. Neither the Collateral Agent nor any of the Lenders shall by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any of the Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any of the Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent or any such Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING LAW. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by each of the Grantors and the Collateral Agent, provided that any provision of this Security Agreement may be waived by the Collateral Agent in a written letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Security Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Collateral Agent and the Lenders and their respective successors and assigns. This Security Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. 16. NOTICES. Notices hereunder may be given by mail or by facsimile transmission, addressed or transmitted to the Person to which it is being given at such Person's address or transmission number set forth in the Credit Agreement and shall be effective (a) in the case of Exhibit H (Page 15) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

Each Grantor may change its address and transmission number by written notice to the Collateral Agent, and the Collateral Agent or any of the Lenders may change its address and transmission number by written notice to each Grantor and, in the case of any of the Lenders, to the Collateral Agent. 17. AUTHORITY OF COLLATERAL AGENT. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as among the Collateral Agent, the Lenders and the Marco Polo Lenders be governed by the Credit Agreement, the Marco Polo Financing Documents and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and each Grantor, the Collateral Agent shall be conclusively presumed to be acting as agent for the Lenders and the Marco Polo Lenders with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority. 18. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH GRANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF MAY BE BROUGHT AGAINST IT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT AND SUCH OTHER LOAN DOCUMENTS, EACH GRANTOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH GRANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO SUCH GRANTOR AT ITS ADDRESS SET FORTH UNDER ITS SIGNATURE BELOW. NOTHING HEREIN AND IN SUCH OTHER LOAN DOCUMENTS SHALL AFFECT THE RIGHT OF THE COLLATERAL AGENT OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR OT COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST EACH GRANTOR IN ANY OTHER JURISDICTION. 19. WAIVERS. (a) EACH GRANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY ACTION DESCRIBED IN PARAGRAPH 18, OR THAT SUCH PROCEEDING WAS BROUGHT IN AN Exhibit H (Page 16) SEVENTH AMENDED AND RESTATED CREDIT AGREEMENT

INCONVENIENT COURT, AND AGREES NOT TO PLEAD OR CLAIM THE SAME. (b) EACH GRANTOR AND THE COLLATERAL AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OR COUNTERCLAIM OF ANY TYPE AS TO ANY MATTER ARISING DIRECTLY OR INDIRECTLY OUT OF OR WITH RESPECT TO THIS AGREEMENT.

The representations and warranties of the Investor contained in Section 3 shall survive the Closing for a period of 18 months after the Closing Date. The covenants and obligations contained in Section 2 and all other covenants and obligations contained in this Agreement shall survive the Closing without limitation. (b) Indemnification Provisions for Benefit of the Investor. (i) Representations and Warranties.

Any due diligence or other investigation by or on behalf of the Investor shall not affect its reliance or right to rely on any representation or warranty made by the Partnership in this Agreement. (ii) Covenants and Obligations. In the event: (x) any of the covenants or obligations of the Partnership in Section 2 or any other covenants or obligations of the Partnership in this Agreement are breached; and (y) the Investor makes a written claim for indemnification against the Partnership pursuant to Section 7(e), then the Partnership agrees to release, indemnify and hold harmless the Investor Indemnitees from and against any Adverse Consequences suffered by the Investor Indemnitees. 17

(c) Indemnification Provisions for Benefit of the Partnership. (i) Representations and Warranties. In the event: (x) any of the representations or warranties of the Investor is breached; (y) there is an applicable survival period pursuant to Section 5(a); and (z) the Partnership makes a written claim for indemnification against the Investor pursuant to Section 7(e) within such survival period, then the Investor agrees to release, indemnify and hold harmless the Partnership Indemnitees from and against any Adverse Consequences suffered by such Partnership Indemnitees by reason of all such breaches.

(d) Matters Involving Third Parties. (i) If any third party shall notify any Party (the "Indemnified Party") with respect to any matter (a "Third Party Claim") that may give rise to a claim for indemnification against any other Party (the "Indemnifying Party") under this Section 5, then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing. Failure to give prompt notice of a Third Party Claim hereunder shall not affect the Indemnifying Party's obligations, except to the extent that the Indemnifying Party is materially prejudiced by such failure to give prompt notice. (ii) The Indemnifying Party shall have the right to assume and thereafter conduct the defense of the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnified Party shall have the right to participate in any matter through counsel of its own choosing at its own expense; provided further, however, that the Indemnifying Party shall pay the fees and expenses of separate counsel for the Indemnified Party if (A) the Indemnifying Party has agreed to pay such fees and expenses or (B) the named parties to any such action or proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that the representation of both parties would be inappropriate due to actual or potential differing interests between them.

(e) Determination of Amount of Adverse Consequences. The Adverse Consequences giving rise to any indemnification obligation hereunder shall be limited to the actual loss suffered by the Indemnified Party (i.e. reduced by any insurance proceeds or other payment or recoupment received, realized or retained by the Indemnified Party as a result of the events giving rise to the claim for indemnification net of any expenses related to the receipt of such proceeds, payment or recoupment, including retrospective premium adjustments, if any), but not reduced by any reduction in Taxes of the Indemnified Party (or the affiliated group of which it is a member) occasioned by such loss or damage. The amount of the actual loss and the amount of the indemnity payment shall be computed by taking into account the timing of the loss or payment, as applicable, using a 10% interest or discount rate, as appropriate. Upon the request of the Indemnifying Party, the Indemnified Party shall provide the Indemnifying Party with information sufficient to allow the Indemnifying Party to calculate the amount of the indemnity payment in accordance with this Section 5(e). (f) Compliance with Express Negligence Rule. ALL RELEASES, DISCLAIMERS, LIMITATIONS ON LIABILITY AND INDEMNITIES IN THIS AGREEMENT, INCLUDING THOSE IN THIS SECTION 5, SHALL APPLY EVEN IN THE EVENT OF THE SOLE, JOINT AND/OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF THE PARTY WHOSE LIABILITY IS RELEASED, DISCLAIMED, LIMITED OR INDEMNIFIED.

the Initial Exchange, the Partnership has issued limited partner interests or increased or decreased (or declared an increase or decrease) in its regular quarterly distribution of Available Cash to holders of its Common Units, in calculating the Exchange Formula, the parties shall use a pro forma Class A Quarterly Distribution amount that assumes that any and all such issuances or increases or decreases occurred in such quarter; provided, however, no pro forma adjustment shall be made for a distribution impacted to any material extent by a non-recurring, extraordinary or similar event. SECTION 2.3 EXERCISE; TOTAL NUMBER OF EXCHANGE UNITS. (a) To exercise the Exchange Right, the Holder shall deliver a written notice (an "EXCHANGE Notice") to each of the Company and the Partnership.

Such third firm shall determine the Total Number of Exchange Units within 15 business days of such referral. The aggregate fees and expense of such firms shall be borne in the following manner: one-half by the Holder and one-fourth each by the Company and the Partnership. The determination of the Total Number of Exchange Units by such third firm shall be final, binding and conclusive on the parties. SECTION 2.4 SOFT CAP. Notwithstanding anything in this Article II to the contrary, in no event shall the number of Exchange Units that are issued to the Holder in any single Exchange exceed that number of Exchange Units that would result in the Holder and/or any of its affiliates directly or indirectly beneficially owning more than 9.9% of any class of equity security of the Partnership which is registered pursuant to Section 12 of the Exchange Act 6

(calculated pursuant to Section 16(a) of the Exchange Act) (the "SOFT CAP"); provided, however, that the parties hereto hereby expressly acknowledge and agree that at all times during the term of this Agreement (a) the Holder shall have the sole duty and responsibility to determine that the number of Exchange Units issued in any Exchange does not exceed the Soft Cap and (b) neither the Partnership nor the Company shall have any obligation to make any independent calculation or otherwise confirm that the number of Exchange Units issued in any such Exchange does not exceed the Soft Cap limitation. SECTION 2.5 TIMING OF EXERCISE OF EXCHANGE RIGHT. (a) The Holder may exercise the Exchange Right at any time after the fifth (5th) anniversary of the Closing Date, subject to earlier exercise upon the occurrence of the events described in Section 2.5(c) below. (b) If (i) the Holder has not elected to exercise the Exchange Right prior to the seventh (7th) anniversary of the Closing Date, at any time thereafter, (ii) the Class B Member has exercised its "drag along" rights under Section 3.11(b) of the Company LLC Agreement, or (iii) the Class A Member transfers the Class A Membership Interest to a Competitor or upon a Change of Control of the Class A Member that results in a Competitor beneficially owning 50% or more of the Voting Stock of the surviving entity, the Partnership (in the case of clauses (i) and (iii)) or the Class B Member (in the case of clause (ii)) may elect to require the Holder to exercise the Exchange Right by delivering written notice to the Holder. The Exchange Formula applicable in the case of an election by the Partnership or the Class B Member under this Section 2.5 shall be calculated in the same manner as specified in Section 2.1 above (and in accordance with Sections 2.2, 2.10 and other applicable provisions of this Article II); provided, however, that in the case of clause (ii), (x) the Holder shall only be required to Exchange that portion of its Class A Membership Interest in excess of that portion for which it did not elect to, or is not permitted to, receive cash consideration pursuant to Section 3.11(b) of the Company LLC Agreement, (y) the value of the Exchange Units to be issued to the Holder shall not be less than the amount dictated by Section 3.11(b)(i) of the Company LLC Agreement and (z) the Exchange made pursuant thereto shall not be subject to the Soft Cap. (c) Notwithstanding the limitations on the Holder's right to exercise the Exchange Right in Section 2.5(a), the Holder may exercise the Exchange Right (i) upon the public announcement of execution of definitive transaction documents relating to (and in no event later than 10 days prior to the consummation of such transaction) the (A) completion of a merger of the Partnership with another entity or (B) completion of the sale or other disposition by the Partnership or the Company of all or substantially all of its assets, or (ii) at any time during the 10 days prior to the completion of a direct or indirect Change of Control of Holding Co., (iii) at any time during the 10 days prior to the completion of a liquidation of the Partnership, (iv) at any time during the 10 days after the declaration by the Partnership of a distribution of Cash from Interim Capital Transactions (as such term is defined in the Partnership Agreement) or (v) at any time after the commencement of a voluntary or an involuntary bankruptcy or similar proceeding against El Paso Corporation or any of its material subsidiaries (including Holding Co. or the Company), if at the time of such exercise there is then pending a proceeding seeking payment pursuant to ERISA from the Company of any amounts due relating to the termination of a benefit plan subject to ERISA or (vi) at the closing of the sale or contribution by the Company of the 7

Highest Incentive Distribution Splits, which sale or contribution is effected in accordance with Section 3.12 of the Company LLC Agreement, if the Holder has timely delivered to the Class B Member the notice of such Exchange Right in accordance with Section 3.12 of the Company LLC Agreement; provided, however, that the foregoing provisions of clauses (i) and (ii) shall not apply if such merger, sale, disposition or Change of Control also triggers the "drag along" rights of Holding Co. contained in Section 3.11(b) of the Company LLC Agreement; and provided, further, that in the case of clause (v) that the Holder may only Exchange that portion of its Class A Membership Interest such that, immediately following such Exchange, the Holder retains not less than 1% of the total Membership Interests (as defined in the Company LLC Agreement) in the Company issued and outstanding at such time. SECTION 2.6 EXCHANGE PROCEDURES. (a) Within five business days after the execution of the Acknowledgement, the Holder shall deliver written notice to each of the Company and the Partnership which notice must include a determination, made in good faith, that either (i) the total number of Exchange Units set forth in the Acknowledgement can be issued to the Holder in compliance with the Soft Cap limitation or (ii) a lesser number of Exchange Units must be issued to the Holder in order to maintain compliance with the limitations of the Soft Cap (the "CONFIRMATION NOTICE"). The Holder shall have sole responsibility and liability for determining the number of Exchange Units so included in the Confirmation Notice. The Company and the Partnership shall be entitled to rely, without independent investigation, entirely upon the number of Exchange Units set forth in the Confirmation Notice by the Holder as to the number of Exchange Units that may be issued to the Holder in compliance with the Soft Cap limitation, and the parties hereto hereby expressly acknowledge and agree that neither the Partnership nor the Company shall have any obligation to make any independent calculation or otherwise confirm that the number of Exchange Units issued complies with the Soft Cap limitation. The Holder shall also deliver to the Partnership, along with such Confirmation Notice, a certificate (a "CLASS A CERTIFICATE") representing not less than the portion of the Class A Membership Interest that is to be exchanged at that time. Within five business days after receipt by the Partnership of a valid Confirmation Notice and Class A Certificate conforming to the requirements of this Section 2.6, the Partnership shall issue to the Holder such number of Exchange Units set forth in the Confirmation Notice in fully certificated form. If such Class A Certificate represents more than the percentage ownership interest in the Company to be exchanged, a new Class A Certificate representing the percentage ownership interest not so exchanged shall be reissued to the Holder. (b) Notwithstanding the foregoing, if any Exchange is effected hereunder following the record date established by the Partnership for its Common Unit Quarterly Distribution for a particular calendar quarter but prior to the record date to be established by the Company for its distribution of Company Available Cash for such quarter, the Holder shall be entitled to receive, upon the date of distribution by the Company, the Class A Quarterly Distribution as if it were still an owner of such Class A Membership Interest on the record date of the Company for its distribution of Company Available Cash for such quarter. For the sake of clarity and to assure that no negative inference is drawn from the language immediately above, in all other circumstances, the Class A Member will be entitled to any distribution from the Company and/or the Partnership if it is the owner of a membership interest of the Company (including any unexchanged Class A Membership Interest) or partnership interest of the Partnership, 8

respectively, on the applicable record date established for such distribution subject to the provisions of the Company LLC Agreement and the Partnership Agreement. . SECTION 2.7 ADDITIONAL EXCHANGES. (a) If the effect of the application of the Soft Cap is to cause the Partnership to issue less than the Total Number of Exchange Units to the Holder in the initial Exchange pursuant to this Article II (the "INITIAL EXCHANGE"), on the first business day of each fiscal quarter of the Partnership commencing thereafter the Holder shall provide written notice (an "UPDATE NOTICE") to the Company and Partnership which must include a determination, made in good faith, whether the Holder may receive additional Exchange Units in compliance with the limitations of the Soft Cap and, if so, the requested number of additional Exchange Units to be issued to the Holder ("ADDITIONAL EXCHANGE UNITS") in exchange for the contribution of a corresponding portion (calculated in accordance with the Exchange Formula) of the Holder's remaining Class A Membership Interests; provided, however, that the maximum number of Additional Exchange Units that the Holder may request to be issued pursuant to any Update Notice, and that the Partnership shall be obligated to issue in response thereto, may not exceed the lesser of (i) the excess of the Total Number of Exchange Units over the sum of all Exchange Units issued to the Holder prior to the date of such Update Notice (including Exchange Units issued in the Initial Exchange and all Additional Exchange Units issued in any subsequent Exchanges) and (ii) the maximum number of Additional Exchange Units that may be issued to the Holder in compliance with the limitation of the Soft Cap; provided, further, the Company and the Partnership shall be entitled to rely, without independent investigation, entirely upon the number of Additional Exchange Units set forth by the Holder in the Update Notice as to the number of Exchange Units that may be issued to the Holder in compliance with the limitation set forth in clause (ii) above, and the parties hereto hereby expressly acknowledge and agree that neither the Partnership nor the Company shall have any obligation to make any independent calculation or otherwise confirm that such number of Additional Exchange Units issued complies with the limitation set forth in clause (ii) above. (b) If the Partnership receives a valid Update Notice requesting the issuance of Additional Exchange Units, the Holder shall also deliver to the Partnership, along with such Update Notice, a Class A Certificate representing not less than the portion of the Class A Membership Interest that is to be exchanged for such Additional Exchange Units. Within five business days of receipt of such Update Notice and Class A Certificate conforming to the requirements of Sections 2.7(a) and 2.7(b), the Partnership shall issue to the Holder such number of Additional Exchange Units requested in the Update Notice in fully certificated form and, if such Class A Certificate represents more than the percentage ownership interest in the Company to be exchanged, a new Class A Certificate represented the percentage ownership interest not so exchanged shall be reissued to the Holder. SECTION 2.8 EXCHANGE PERIOD. If the Partnership issues less than the Total Number of Exchange Units in the Initial Exchange, the period from the date of such Initial Exchange through the date of the Exchange after which all of the Total Number of Exchange Units will have been issued to the Holder shall be known, for purposes of the Company LLC Agreement, LLC Purchase Agreement or otherwise, as the "EXCHANGE PERIOD." 9

SECTION 2.9 REFLECTION OF REDUCED SHARING RATIO. Promptly following each Exchange pursuant to this Article II, (a) the Company's Register (as defined in the Company LLC Agreement) shall be updated in compliance with the procedures set forth therein to reflect the reduced Sharing Ratio (as defined in the Company LLC Agreement) attributable to the Class A Membership Interests as a result of such Exchange, such reduction to be effective as of the same date as the date of the effectiveness of the amendment to the Partnership Agreement referred to in Section 3.3 that corresponds to such Exchange. SECTION 2.10 ANTI-DILUTION PROVISIONS. During the period that commences upon the date of the initial election to exercise the Exchange Right and continues for so long as less than the Total Number of Exchange Units have been issued to the Holder pursuant to the terms of this Article II, the excess of the Total Number of Exchange Units over the aggregate number of Exchange Units issued in all prior Exchanges (such excess, the "UNISSUED EXCHANGE UNITS") shall be subject to adjustment from time to time upon the happening of certain events as follows: (a) Reorganization, Merger or Consolidation. If the Partnership reorganizes, merges, consolidates or otherwise combines with another Person in a transaction whereby all of the holders of Common Units will receive securities, property or assets of the Partnership or its successor payable with respect to or in exchange for each Common Unit held, lawful and adequate provision shall be made whereby the Holder shall have the right to receive (in lieu of the Unissued Exchange Units), upon each subsequent Exchange following the consummation of such transaction, the number of securities, property or assets of the Partnership or its successor resulting from such reorganization, merger, consolidation or other transaction as would have been issued or payable to the Holder if the Holder had held a number of Common Units equal to (and in lieu of) the total number of Unissued Exchange Units immediately prior to the consummation of such transaction. The foregoing provisions of this Section 2.10(a) shall similarly apply to successive reorganizations, mergers, consolidations or other applicable transactions and to the stock or securities of any other Person that are at the time receivable upon exercise of the Exchange Right. (b) Reclassification, etc. If the Partnership, by reclassification of securities or otherwise, changes the Common Units or any other securities as to which the Exchange Right may apply hereunder into the same or a different number of securities of any other class or classes, each subsequent Exchange in respect of Unissued Exchange Units shall thereafter represent the right to acquire upon each such Exchange such number and kind of securities as would have been issuable, as the result of such change, with respect to or in exchange for a number of Common Units equal to the total number of Unissued Exchange Units. (c) Subdivision or Combination; Unit Dividends. If the Partnership shall split, divide or combine its outstanding Common Units or declare and pay a dividend on its outstanding Common Units which consists of additional Common Units (including a split effected in the form of a dividend), then the total number of Unissued Exchange Units shall be adjusted, as of the opening of business on the effective date of such split, subdivision or combination or the day after the day upon which such dividend or other distribution is paid to unitholders, as the case may be, to a new total number of Unissued Exchange Units determined by multiplying the total number of Unissued Exchange Units immediately prior to such payment or other distribution by a fraction (i) the numerator of which shall be the total number of outstanding Common Units 10

immediately after such split, dividend, combination or distribution and (ii) the denominator of which shall be the total number of outstanding Common Units immediately prior to such split, dividend, combination or distribution. (d) Other Distributions on Common Units. If the Partnership shall make a distribution on its Common Units which consists of (i) limited partner interests of the Partnership other than additional Common Units, evidences of its indebtedness, or assets (including distributions of Cash from Interim Capital Transactions or securities (other than Common Units), but excluding distributions of Cash from Operations), then the Holder shall be entitled to receive, upon each Exchange for Unissued Exchange Units, that portion of any such distribution which the Holder would have been entitled to receive, had such Exchange occurred immediately prior to the record date of such distribution; provided, however, that if any such distribution consists of property which has a limited life or expiration date (including but not limited to options, warrants or similar instruments), the Holder shall be entitled to receive such property on the date of such distribution. At the time of the record date established for any such distribution, the Partnership shall allocate sufficient reserves to ensure the timely and full performance of the provisions of this Section 2.10(d). (e) Self Tender. If (i) the Partnership shall engage in a tender offer for more than 10% of the Common Units issued and outstanding at such time and (ii) such tender offer is closed and payment is made for the Common Units purchased therein for a purchase price per unit that is at least 5% greater than the closing sales price per Common Unit on the trading day immediately preceding the announcement of such tender offer (the "PRE-TENDER VALUE"), then the Holder shall be entitled to receive, upon each Exchange for Unissued Exchange Units (in addition to such Exchange Units), the excess of the purchase price per Common Unit paid upon closing of the tender offer over the Pre-Tender Value per Common Unit multiplied by the total number of Unissued Exchange Units which would have been sold by the Holder if it tendered all of the Unissued Exchange Units to the Partnership in such tender offer. Upon the closing of any such tender offer, the Partnership shall allocate sufficient reserves to ensure the timely and full performance of the provisions of this Section 2.10(e). (f) No Other Adjustments. Other than specifically as set forth above in this Section 2.10, no adjustment shall be made to the total number Unissued Exchange Units as a result of or pursuant to the granting or issuance by the Partnership of additional Common Units, or any security convertible thereinto or exercisable or exchangeable therefore, including without limitation(i) the issuance of Common Units or any other security of the Partnership or any affiliate thereof (including securities convertible into or exchangeable for Common Units) pursuant to an underwritten public offering or a private placement, (ii) the issuance of Common Units or any other security of the Partnership or any affiliate thereof (including securities convertible into or exchangeable for Common Units) as consideration in an acquisition transaction, (iii) the issuance of Common Units or any other security of the Partnership or any affiliate thereof (including securities convertible into or exchangeable for Common Units) in payment or satisfaction of any dividend upon or distribution to any class of unit or equity security of the Partnership other than Common Units and (iv) the issuance of options, restricted Common Units or "phantom" units exercisable for or that upon vesting become Common Units, or the issuance of Common Units upon the exercise or vesting or such options or rights, to 11

officers, employees or directors of, or consultants to, the Partnership, the Company or any of their affiliates. (g) No Multiple Adjustments. In the event of any one circumstance which may give rise to an adjustment of the total number of Unissued Exchange Units under one or more of Sections 2.10(a) through 2.10(e) above, the Partnership may only apply the provisions of one of such paragraphs if necessary in order to avoid unreasonable results given the circumstances, such determination to be made in the Partnership's good faith and reasonable discretion; provided, however, that a series of steps in a transaction or action shall not be considered one circumstance for the purposes of this Section 2.10(g). (h) Calculation of Adjustments. Upon each occurrence of an event causing an adjustment pursuant to this Section 2.10, the Partnership will promptly (i) calculate such adjustment and retain a record of such calculation at its principal office and (ii) deliver to the Holder a certificate signed by an appropriate officer on behalf of the Partnership, setting forth in reasonable detail the event requiring the adjustment, the method of calculation of the adjustment, and the number of Unissued Exchange Units and/or other securities, property or assets after giving effect to such adjustment (an "ADJUSTMENT CERTIFICATE"). If the Holder does not agree with such calculation, the Holder shall give written notice (an "ADJUSTMENT DISPUTE NOTICE") to the Company and the Partnership within ten business days of the receipt of such Adjustment Certificate. If the parties are unable to mutually agree on the calculation of such adjustment within five business days of receipt by the Company and the Partnership of such Adjustment Dispute Notice, the parties shall each select a firm of independent accountants of nationally recognized standing within five business days, which firms shall then mutually agree upon a third firm of independent accountants of nationally recognized standing and refer the matter to such third firm for resolution within five additional business days. Such third firm shall determine the amount of such adjustment to the Total Number of Exchange Units within 15 business days of such referral. The aggregate fees and expense of such firms shall be borne in the following manner: one-half by the Holder and one-half by the Partnership. The determination by such firm of the calculation of the adjustment described in the Adjustment Notice shall be final, binding and conclusive on the parties. SECTION 2.11 NONSEPARABILITY. The Exchange Right is not separable from the Class A Membership Interest. If the Investor or any subsequent Holder of the Class A Membership Interests transfers such interests (which transfer may only be made in compliance with applicable provisions of the Company LLC Agreement), the Exchange Right shall be transferred to such transferee who shall then constitute the Holder hereunder. SECTION 2.12 NYSE LISTING. Prior to the issuance of any Exchange Units pursuant to this Article II, the Partnership shall cause such Exchange Units to be approved for listing on the New York Stock Exchange or such other exchange or quotation system on which the Common Units are then listed. ARTICLE III [RESERVED] 12

ARTICLE IV REGISTRATION RIGHTS SECTION 4.1 SHELF REGISTRATION STATEMENT. Within 30 days after the Closing Date (the "INITIAL SHELF FILING DEADLINE"), the Partnership shall file with the Commission a "shelf" registration statement on Form S-3 pursuant to Rule 415 under the Securities Act (the "INITIAL SHELF REGISTRATION STATEMENT") providing for the resale of an aggregate of (i) the 3,000,000 Common Units purchased by the Investor pursuant to the Unit Purchase Agreement plus (ii) such number of Exchange Units that may be issued to the Holder pursuant to Article II based on the number of Common Units outstanding on the Closing Date. SECTION 4.2 ADDITIONAL COMMON UNITS. If the Initial Shelf Registration Statement, even if supplemented or amended, does not have sufficient availability to provide for the resale of (x) Exchange Units issued to the Holder or (y) any Common Units issued to the Holder by the Partnership pursuant to the provisions in the Company LLC Agreement relating to the exercise by the Holder or the Class B Member, as the case may be, of their respective "tag along" or "drag along" rights provided therein ("TAG/DRAG UNITS"), the Holder may request that the Partnership file with the Commission one additional "shelf" registration statement on Form S-3 pursuant to Rule 415 under the Securities Act to accommodate any resale of Tag/Drag Units or Exchange Units in such amounts as are requested at such time by the Holder in writing (a "SHELF NOTICE"). The Partnership shall file such additional "shelf" registration statement (with the Initial Shelf Registration Statement, a "SHELF REGISTRATION STATEMENT"), if any, within 30 days after receipt by the Partnership of a written request from the Holder (with the Initial Shelf Filing Deadline, a "SHELF FILING DEADLINE"). SECTION 4.3 EFFECTIVENESS. (a) Subject to the provisions of this Article IV, the Partnership shall use its best efforts to cause (i) the Initial Shelf Registration Statement to be declared effective prior to the expiration of the Initial Lock-up Period (as defined below) (the "INITIAL EFFECTIVENESS TARGET DATE") and (ii) any subsequent Shelf Registration Statement to be declared effective no later than 90 days after delivery to the Partnership by the Holder of a Shelf Notice (with the Initial Effectiveness Deadline, the "EFFECTIVENESS TARGET DATE") and in either case shall use best efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended to the extent necessary to assure that it is available for resale of the Common Units by the Holder and that it conforms in all material respects with the requirements the Securities Act, in each case during the entire period (the "EFFECTIVENESS PERIOD") beginning on the date such Shelf Registration Statement shall first be declared effective under the Securities Act and ending on the earlier to occur of (i) the sale pursuant to a Shelf Registration Statement of all of the Registrable Securities registered under such Shelf Registration Statement and (ii) the date on which all of the Common Units registered under such Shelf Registration Statement are no longer Registrable Securities. (b) The "INITIAL LOCK-UP PERIOD" shall be earliest to occur of a (i) the date that is the earlier of 90 days or the number of days agreed to by the Partnership and the underwriters in the applicable underwriting agreement as a lock-up period in connection with any primary offering of the Partnership that closes prior to November 30, 2003, (ii) waiver by the underwriters of any such offering of any lock-up related thereto, (iii) after the closing of any such offering, the date 13

of any sale of common units by the Partnership, the Company, El Paso Corporation or its subsidiaries (other than pursuant to the exercise of existing options, warrants or similar securities or agreements or as consideration in an acquisition), or (iv) February 28, 2004. SECTION 4.4 INFORMATION FURNISHED BY HOLDER. The Holder shall furnish to the Partnership in writing, as soon as practicable after the Closing Date (in the case of the Initial Shelf Registration Statement) or after requesting the filing of an additional Shelf Registration Statement pursuant to Section 4.2, the information specified in Items 507 and 508 of Regulation S-K under the Securities Act and any other information reasonably requested by the Partnership for inclusion in the applicable Shelf Registration Statement pursuant to the Securities Act. Notwithstanding Sections 4.1 and 4.2, the Partnership shall not be required to file any such Shelf Registration Statement until the Holder has complied with the immediately preceding sentence. In addition, the Holder shall promptly furnish to the Partnership (i) any additional information required to be disclosed in such Shelf Registration Statement in order to make the information previously furnished to the Partnership by the Holder not materially misleading and (ii) any additional information as may be reasonably requested by the Partnership for inclusion in any new prospectus or prospectus supplement or post-effective amendment. SECTION 4.5 REGISTRATION PROCEDURES. (a) In connection with each Shelf Registration Statement, the Partnership shall comply with all the provisions of Section 4.5(b) hereof and shall, in accordance with Sections 4.1, 4.2, 4.3 and 4.4 hereof, prepare and file with the Commission each Shelf Registration Statement relating to the registration on Form S-3 under the Securities Act. (b) In connection with each Shelf Registration Statement and any related prospectus or prospectus supplement required by this Agreement to permit the sale or resale of Common Units, the Partnership shall: (i) Subject to any notice by the Partnership in accordance with this Section 4.5(b) of the existence of any fact or event of the kind described in Section 4.5(b)(iii)(D), use its best efforts to keep the Shelf Registration Statement continuously effective during the Effectiveness Period; upon the occurrence of any event that would cause the Shelf Registration Statement or the related prospectus or prospectus supplement (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Registrable Securities during the Effectiveness Period, the Partnership shall file promptly an appropriate amendment or supplement to or a document to be incorporated by reference into the Shelf Registration Statement or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its best efforts to cause any such amendment to be declared effective and the Shelf Registration Statement and the related prospectus or prospectus supplement to become usable for their intended purposes as soon as practicable thereafter. Notwithstanding anything in this Agreement to the contrary, the Partnership may suspend the effectiveness or use of and elect not to keep current the Shelf Registration Statement by written notice to the Holder for a period not to exceed an aggregate of 30 days in any 90-day period (each such period a "SUSPENSION PERIOD") if: 14

(x) an event occurs and is continuing as a result of which the Shelf Registration Statement would, in the Partnership's reasonable judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and (y) the Partnership reasonably determines that the disclosure of such event at such time would or could reasonably be expected to either (i) have a material adverse effect on the business or prospects of the Partnership and its subsidiaries, taken as a whole, or (ii) adversely affect a material financing, acquisition or other transaction (existing or planned); provided, that (A) in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which would impede the Partnership's ability to consummate such transaction, the Partnership may extend a Suspension Period from 30 days to 45 days and (B) the Suspension Periods shall not exceed an aggregate of 90 days in any 365-day period. The Holder, by its acceptance of a Registrable Security, agrees to hold in confidence any communication by the Partnership relating to an event described in Section 4.5(b)(i)(x) and (y) or Section 4.5(b)(iii)(D). Notwithstanding the foregoing, the Holder may not use the Shelf Registration Statement or related prospectus during the Initial Lock-up Period. (ii) Prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the prospectus. (iii) Advise the underwriter(s), if any, and, in the case of (A), (C) and (D) below, the Holder promptly and, if requested by such Persons, to confirm such advice in writing: (A) when the prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any post-effective amendment thereto, when the same has become effective; (B) of any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the prospectus or for additional information relating thereto; (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable 15

Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes; or (D) of the existence (but not the nature) of any fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the Shelf Registration Statement, the related prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement, the related prospectus or any amendment or supplement thereto in order to make the statements therein not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Registrable Securities under state securities or Blue Sky laws, the Partnership shall use its best efforts to obtain the withdrawal or lifting of such order at the earliest possible time. (iv) Furnish to counsel for the Holder and each of the underwriter(s), if any, before filing with the Commission, a copy of the Shelf Registration Statement and copies of any prospectus included therein or any amendments or supplements to either of the Shelf Registration Statement or prospectus (other than documents incorporated by reference after the initial filing of the Shelf Registration Statement), which documents will be subject to the review of such counsel and underwriter(s), if any, for a period of three business days, and the Partnership will not file the Shelf Registration Statement or prospectus or any amendment or supplement to the Shelf Registration Statement or prospectus (other than documents incorporated by reference) to which such counsel or the underwriter(s), if any, shall reasonably object within three business days after the receipt thereof. (v) Make available pursuant to a confidentiality and non-use agreement at reasonable times for inspection by one or more representatives of the Holder any underwriter, if any, participating in any distribution pursuant to the Shelf Registration Statement, and any attorney or accountant retained by the Holder or any of the underwriter(s), all financial and other records, pertinent corporate documents and properties of the Partnership as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities and to supply all information reasonably requested by any such representative or representatives of the Holder, underwriter, attorney or accountant in connection with the Shelf Registration Statement after the filing thereof and before its effectiveness; provided, however, that the Holder shall be responsible for ensuring that any such information shall be kept confidential and not used for any purpose other than as contemplated hereby. (vi) If requested by the Holder or the underwriter(s), if any, incorporate in the Shelf Registration Statement or prospectus, pursuant to a prospectus supplement or post-effective amendment if necessary, such non-confidential information as the Holder and underwriter(s), if any, may reasonably request to have included therein, including, without limitation: (1) information relating to the "Plan of Distribution" of the Registrable Securities, (2) information with respect to the number of Registrable Securities being sold, (3) the purchase price being paid therefor and (4) any other terms of the offering of the Registrable Securities to be sold in such 16

offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as reasonably practicable after the Partnership is notified of the matters to be incorporated in such prospectus supplement or post-effective amendment. (vii) Furnish to the Holder and each of the underwriter(s), if any, without charge, at least one copy of the Shelf Registration Statement, as first filed with the Commission, and of each amendment thereto (and any documents incorporated by reference therein or exhibits thereto (or exhibits incorporated in such exhibits by reference) as such Person may request in writing). (viii) Deliver to the Holder and each of the underwriter(s), if any, without charge, as many copies of the prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request. (ix) In the event of an Underwritten Offering, the Partnership shall enter into a standard underwriting agreement with the underwriters and shall: (A) upon request, furnish to the Holder and each underwriter, if any, in such substance and scope as they may reasonably request and as are customarily made by the Partnership to underwriters in primary underwritten offerings, upon the date of closing of any sale of Registrable Securities in an Underwritten Offering: (1) an officer's certificate, dated the date of such closing, confirming, as of the date thereof, such matters as such parties may reasonably request; (2) opinions, each dated the date of such closing, of counsel (inside and outside) to the Partnership covering such matters as are customarily covered in legal opinions to underwriters in connection with primary underwritten offerings of securities by the Partnership; and (3) customary comfort letters, dated the date of such closing, from the Partnership's independent accountants (and from any other accountants whose report is contained or incorporated by reference in the Shelf Registration Statement), in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with primary underwritten offerings of securities; provided, that if the Partnership has used its best efforts to obtain such letters, the Partnership shall not be responsible if the accountants do not agree to deliver same; (B) set forth in full in the underwriting agreement, if any, indemnification provisions and procedures which provide rights no less protective than those set forth in Section 4.10 hereof with respect to all parties indemnified; and (C) deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with clause (A) above and with any 17

customary conditions contained in the underwriting agreement or other agreement entered into by the Holder pursuant to this clause (ix). (x) Before any public offering of Registrable Securities, cooperate with the Holder, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Registrable Securities under the securities or Blue Sky laws of such jurisdictions as the Holder or underwriter(s), if any, may reasonably request and do any and all other acts or things necessary or reasonably advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the Shelf Registration Statement; provided, however, that the Partnership shall not be required (A) to register or qualify as a foreign limited partnership or a dealer of securities where it is not now so qualified or to take any action that would subject it to the service of process in any jurisdiction where it is not now so subject or (B) to subject itself to taxation in any such jurisdiction if it is not now so subject. (xi) Cooperate with the Holder and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends (unless required by applicable securities laws); and enable such Registrable Securities to be in such denominations and registered in such names as the Holder or the underwriter(s), if any, may reasonably request within a reasonable time before any sale of Registrable Securities made by such underwriter(s). (xii) Use its best efforts to cause the Registrable Securities covered by any Shelf Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Registrable Securities, subject to the proviso in clause (x) above. (xiii) Subject to Section 4.5(b)(i) hereof, if any fact or event contemplated by Section 4.5(b)(iii)(D) hereof shall exist or have occurred, use its best efforts to prepare a supplement or post-effective amendment to the Shelf Registration Statement or related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Registrable Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. (xiv) Provide CUSIP numbers for all Registrable Securities not later than the effective date of the Shelf Registration Statement and provide the transfer agent with certificates for the Common Units that are in a form eligible for transfer in accordance with applicable requirements. (xv) Cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by any underwriter that is required to be retained in accordance with the rules and regulations of the NASD. (xvi) Otherwise use its best efforts to comply with all applicable rules and regulations of the Commission and all reporting requirements under the rules and regulations of the Exchange Act. 18

(c) The Holder agrees that, upon receipt of any notice from the Partnership of the existence of any fact of the kind described in Section 4.5(b)(iii)(D) hereof, the Holder will, and will use its best efforts to cause any underwriter(s) in an Underwritten Offering to, forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until: (xvii) the Holder has received copies of the supplemented or amended prospectus contemplated by Section 4.5(b)(xiii) hereof; or (xviii) the Holder is advised in writing by the Partnership that the use of the prospectus may be resumed. If so directed by the Partnership, the Holder will deliver to the Partnership (at the Partnership's expense) all copies, other than permanent file copies then in the Holder's possession, of the prospectus covering such Registrable Securities that was current at the time of receipt of such notice of suspension. SECTION 4.6 STOP TRANSFER INSTRUCTIONS. The Partnership may give such stop transfer instructions to its transfer agent as it shall deem reasonably necessary to prevent any sale of shares of Common Units under a Shelf Registration Statement at any time when the Holder is not permitted to make such a sale pursuant to this Article IV. SECTION 4.7 NO PIGGYBACK OR OTHER REGISTRATION RIGHTS. Other than as set forth in this Article IV, the Holder shall have no registration rights with respect to Common Units beneficially owned by the Holder (including any "piggyback" registration rights). In addition, the Partnership shall not be required to include any Common Units acquired by the Holder for resale under a Shelf Registration Statement other than the Common Units that constitute Registrable Securities under this Agreement. SECTION 4.8 REGISTRATION EXPENSES. The Partnership shall bear all expenses incident to the filing of any Shelf Registration Statement, including without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all fees and disbursements of counsel for the Partnership; (v) all application and filing fees in connection with listing or quoting, as the case may be, the Common Units on each securities exchange or automated quotation system on which the Common Units are then listed or quoted; and (vi) all fees and disbursements of independent certified public accountants of the Partnership (including the expenses of any special audit and comfort letters required by or incident to such performance); provided, however, the Holder shall bear the all the cost of (x) any discount or selling commission incurred in connection with the sale of any of such Common Units and (y) any fees and disbursements of counsel for the Holder or any other professional advisors engaged by the Holder. SECTION 4.9 RULE 144. The Partnership covenants that it will file at times chosen by the Partnership any reports required to be filed by it under Section 13 or 15(d) of the Exchange Act, all to the extent required from time to time to enable the Holder to sell Registrable Securities without registration under the Act within the limitation of the exemptions provided by Rule 144 under the Act, as such Rule may be amended from time to time (or any similar rule or 19

regulation hereafter adopted by the Commission). Upon the reasonable request of the Holder, the Partnership will deliver to the Holder a written statement as to whether it has complied with such requirements. The Partnership further covenants that, upon the request of the Holder, it will take any further actions reasonably necessary to permit the Holder to transfer the Common Units under Rule 144, including, without limitation, causing any restrictive legends to be removed from any certificates representing Common Units in accordance with the terms of such legends. SECTION 4.10 INDEMNIFICATION. (a) For purposes of this Section 4.10, the following terms shall have the following meanings: (i) "PRELIMINARY PROSPECTUS" means any preliminary prospectus supplement to the base prospectus included in a Shelf Registration Statement, together with such base prospectus, that describes the Common Units and the offering thereof, filed with the Commission pursuant to Rule 424(a) of the rules and regulations of the Commission under the Act and used prior to the filing of the Prospectus. (ii) "PROSPECTUS" means the final prospectus supplement, in the form first filed pursuant to Rule 424(b) under the Act, together with the base prospectus included in the Shelf Registration Statement; and any reference herein to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act, as of the date of such Preliminary Prospectus or Prospectus, as the case may be; and any reference to any amendment or supplement to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such Preliminary Prospectus or Prospectus, as the case may be, under the Exchange Act. (iii) "REGISTRATION STATEMENT" means the various parts of the Shelf Registration Statement, including all exhibits thereto and including (i) the information contained in the form of final prospectus supplement to the base prospectus included in the Shelf Registration Statement, filed with the Commission after the date hereof pursuant to Rule 424(b) under the Act in accordance with this Article IV and deemed by virtue of Rule 430A under the Act to be part of the Shelf Registration Statement at the time it was declared effective and (ii) the documents incorporated by reference in such final prospectus supplement. (b) Each of the Partnership and the Company, jointly and severally, will indemnify and hold harmless the Holder against any losses, claims, damages or liabilities, joint or several, to which the Holder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Holder for any legal or other expenses reasonably incurred by the Holder in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Partnership and the Company shall not be 20

liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Partnership by the Holder expressly for use therein. (c) The Holder will indemnify and hold harmless the Partnership and the Company against any losses, claims, damages or liabilities to which either the Partnership, the Company or both may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, Registration Statement or Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, Registration Statement or Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Partnership by the Holder expressly for use therein; and will reimburse the Partnership and the Company for any legal or other expenses reasonably incurred by the Partnership and the Company in connection with investigating or defending any such action or claim as such expenses are incurred. (d) Promptly after receipt by an indemnified party under Sections 4.10(b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. 21

(e) If the indemnification provided for in this Section 4.10 is unavailable to or insufficient to hold harmless an indemnified party under Sections 4.10 (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Partnership and the Company on the one hand and the Holder on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership and the Company on the one hand or Holder on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership, the Company and the Holder agree that it would not be just and equitable if contributions pursuant to this Section 4.10(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 4.10(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 4.10(e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.10(e), the Holder shall not be required to contribute any amount in excess of the amount by which the aggregate consideration received by the Holder from the sale of any Registrable Securities pursuant to the relevant Shelf Registration Statement exceeds the amount of any damages which the Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (f) The obligations of the Partnership and the Company under this Section 4.10 shall be in addition to any liability which the Partnership and the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Holder within the meaning of the Act; and the obligations of the Holder under this Section 4.10 shall be in addition to any liability which the Holder may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Partnership or the Company within the meaning of the Securities Act.

EXHIBIT 10.V INCENTIVE DISTRIBUTION REDUCTION AGREEMENT This INCENTIVE DISTRIBUTION REDUCTION AGREEMENT (this "AGREEMENT") is entered into as of October 1, 2003 by and between GulfTerra Energy Company, L.L.C., a Delaware limited liability company (the "COMPANY"), and GulfTerra Energy Partners, L.P., a Delaware limited partnership (the "PARTNERSHIP"). RECITALS WHEREAS, GulfTerra GP Holding Company, a Delaware corporation ("HOLDING CO.") and Goldman Sachs & Co., a New York limited partnership (the "INVESTOR"), are parties to that certain Purchase and Sale Agreement, dated October 1, 2003 (the "LLC PURCHASE AGREEMENT"), whereby the Investor will purchase from Holding Co. the Class A Membership Interests of the Company (as issued and outstanding on the date of determination, the "CLASS A MEMBERSHIP INTERESTS") from Holding Co.; WHEREAS, the Partnership and the Investor are parties to that certain Purchase and Sale Agreement, dated October 1, 2003 (the "UNIT PURCHASE AGREEMENT," and with the LLC Purchase Agreement, the "PURCHASE AGREEMENTS"), whereby the Investor will purchase from the Partnership 3,000,000 newly issued Series A common units representing limited partner interests in the Partnership ("COMMON UNITS") from the Partnership; WHEREAS, the Company, the Partnership and the Investor are parties to that certain Exchange and Registration Rights Agreement, dated October 1, 2003 (the "EXCHANGE AGREEMENT,") whereby, under certain circumstances described therein, the Investor may contribute its Class A Membership to the Partnership in exchange for Exchange Units; WHEREAS, the Partnership and the Company have agreed that upon each such Exchange pursuant to the Exchange Agreement, the Partnership will deliver the Class A Membership Interest received in such Exchange to the Company for cancellation, and the Company will cause the Incentive Distribution Rights (as defined therein) to be reduced as is provided in this Agreement; NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows. ARTICLE I SECTION 1.1 DEFINITIONS. In addition to the terms defined elsewhere herein, capitalized terms used herein but not defined herein shall have the meanings assigned to such terms in the Exchange Agreement (which is attached as Exhibit A hereto). ARTICLE II INCENTIVE DISTRIBUTION REDUCTION SECTION 2.1 TRANSFER AND REDUCTION. The parties hereto agree and acknowledge that, immediately following any Exchange pursuant to Article II of the Exchange Agreement, (i) the

Class A Membership Interest contributed by the Investor to the Partnership shall be transferred to the Company, (ii) upon receipt thereof, such Class A Membership Interest shall be cancelled by the Company and (iii) the Incentive Distributions payable by the Partnership to the Company shall be reduced by an aggregate dollar amount (the "REDUCTION AMOUNT") equal to the aggregate dollar amount of the most recent Common Unit Quarterly Distribution prior to the Initial Exchange that would have been paid on the number of Exchange Units issued in such Exchange. The Reduction Amount shall be achieved by reducing the percentage allocation to the Company at each target level of the Incentive Distributions (the "HIGH SPLIT ALLOCATION PERCENTAGES") by the same percentage (the "STANDARD REDUCTION FACTOR"); provided, however, that in determining the Standard Reduction Factor, if any distribution is to be paid in respect of an Incentive Distribution target level, the Company shall always receive no less than 1% of such distribution (as required by the Partnership Agreement). The calculation and application of the Standard Reduction Factor is illustrated in the examples set forth in Exhibit B hereto. The new High-Split Allocation Percentages determined pursuant to this Section 2.1 shall be used to determine the Incentive Distributions payable by the Partnership to the Company for all quarterly distributions by the Partnership subsequent to any reduction pursuant to this Section 2.1. The actions described in the initial sentence of this Section 2.1 shall be deemed to occur automatically and in immediate succession. Any administrative actions required to memorialize such steps (such as transfer and cancellation of physical certificates and amendment of the Partnership Agreement) shall be completed within three business days. SECTION 2.2 AMENDMENTS TO PARTNERSHIP AGREEMENT. In order to give effect to the reduction of the Highest-Split Percentage pursuant to Section 2.1, concurrently therewith, the Company shall amend the Partnership Agreement, in compliance with Section 15.1 thereof, (i) to reflect each reduction in the Highest-Split Percentage and (ii) to make any other changes necessary to effect such reduction in the Incentive Distributions payable by the Partnership to the Company. SECTION 2.3 CERTIFICATE; DISPUTE RESOLUTION. Upon each reduction of the Highest-Split Percentage pursuant to Section 2.1, the Partnership will within 10 business days of the Exchange by the Holder deliver to the Company (i) a certificate signed by an appropriate officer on behalf of the Partnership that sets forth in reasonable detail the calculation of the new Highest-Split Percentage pursuant to the Reduction Formula and (ii) a copy of the amendment to the Partnership Agreement effected pursuant to Section 2.2. If the Company does not agree with the new Highest-Split Percentage, such party shall give written notice (a "REDUCTION DISPUTE NOTICE") to the Partnership within five business days of the receipt of such certificate. If the parties are unable to mutually agree on the new Highest-Split Percentage within five business days of receipt of such Adjustment Dispute Notice by the other parties, the Company and the Partnership shall each select a firm of independent accountants of nationally recognized standing within five business days, which firms shall then mutually agree upon a third firm of independent accountants of nationally recognized standing and refer the matter to such third firm for resolution within five additional business days. Such third firm shall determine the new Highest-Split Percentage pursuant to the Reduction Formula within 15 business days of such referral The aggregate fees and expense of such firms shall be borne in the following manner: one-half by the Company and one-half by the Partnership. The determination by such third firm of the new Highest-Split Percentage shall be final, binding and conclusive on the parties. 2
