EL PASO ENERGY PARTNERS, L.P. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. BASIS OF PRESENTATION We prepared this Quarterly Report on Form 10-Q under the rules and regulations of the United States Securities and Exchange Commission (SEC). Because this is an interim period filing presented using a condensed format, it does not include all of the disclosures required by generally accepted accounting principles. You should read it along with our current report on Form 8-K/A dated July 19, 2002, which includes a summary of our significant accounting policies and other disclosures. The financial statements as of September 30, 2002, and for the quarters and nine months ended September 30, 2002 and 2001, are unaudited. We derived the balance sheet as of December 31, 2001, from the audited balance sheet filed in our current report on Form 8-K/A dated July 19, 2002. In our opinion, we have made all adjustments, all of which are of a normal, recurring nature, to fairly present our interim period results. Due to the seasonal nature of our businesses, information for interim periods may not indicate the results of operations for the entire year. In addition, prior period information presented in these financial statements includes reclassifications which were made to conform to the current period presentation. These reclassifications have no effect on our previously reported net income or partners' capital. Additionally, we have reflected the results of operations from our Prince assets disposition as discontinued operations for all periods presented. See Note 3 for a further discussion of the Prince Assets Disposition. Our accounting policies are consistent with those discussed in our Form 8-K/A dated July 19, 2002, except as discussed below. Revenues and Cost of Natural Gas Prior to our April 2002 acquisition of the Texas and New Mexico assets, which we refer to as the EPN Holding assets, our cost of natural gas consisted primarily of gas purchased at El Paso Intrastate Alabama for resale. As a result of our acquisition of the EPN Holding assets, we are now incurring additional cost of natural gas related to system imbalances and for the purchase of natural gas as part of our producer services activities. As a convenience for our producers, we may purchase natural gas from them at the wellhead at an index price less an amount that compensates us for our gathering services. We then sell this gas into the open market at points on our system at the same index price. We reflect these sales in our revenues and the related purchases as cost of natural gas. Goodwill and Other Intangible Assets On January 1, 2002, we adopted Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. Our adoption of this standard did not have a material effect on our financial statements. Asset Impairments On January 1, 2002, we adopted SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 changed the accounting requirements related to when an asset qualifies as held for sale or as a discontinued operation and the way in which we evaluate assets for impairment. It also changes the accounting for discontinued operations such that we can no longer accrue the estimate for future - --------------- As generally used in the energy industry and in this document, the following terms have the following meanings:

/d = per day Mcf = thousand cubic feet Bbl = barrel MDth = thousand dekatherms MBbls = thousand barrels MMcf = million cubic feet Bcf = billion cubic feet MMBbls = million barrels When we refer to cubic feet measurements, all measurements are at 14.73 pounds per square inch.

operating losses but report them as they are incurred. We applied SFAS No. 144 in accounting for our Prince assets, which met all the requirements to be treated as an asset held for sale, in April 2002. See Note 3, Prince Assets Disposition, for further information. 2. ACQUISITIONS Proposed San Juan Assets Acquisition In July 2002, we entered into a letter of intent with El Paso Corporation, the indirect parent of our general partner, to acquire for $782 million El Paso Corporation's natural gas gathering system located in the San Juan Basin of New Mexico, including El Paso Corporation's remaining interests in the Chaco cryogenic natural gas processing plant; natural gas liquids (NGL) transportation and fractionation assets located in Texas; and an oil and natural gas gathering system located in the deeper water regions of the Gulf of Mexico, referred to collectively as the San Juan assets. As part of this transaction, El Paso Corporation will be required to repurchase the Chaco processing plant from us for $77 million in October 2021, and at that time, we will have the right to lease the plant from El Paso Corporation for a period of ten years with the option to renew the lease annually thereafter. The purchase price of $782 million is subject to adjustments primarily for working capital and capital expenditures. The parties' obligations under the letter of intent are subject to the satisfaction of specified conditions, including negotiating and executing definitive agreements, obtaining other third-party approvals and consents, obtaining satisfactory results from ongoing due diligence and obtaining financing satisfactory to us. We expect to close the transaction in the fourth quarter of 2002. Ultimately, we expect to finance our acquisition of the San Juan assets through long-term debt and equity. The equity component of the proposed acquisition contemplates us issuing to El Paso Corporation up to $350 million of our Series C units, a new class of our limited partner interests. The potential $350 million Series C issuance will be reduced by the proceeds from any common unit issuance we may consummate before the closing of the San Juan assets acquisition. The Series C units will be similar to our existing common units, except that the Series C units will be non-voting. After April 30, 2003, El Paso Corporation (or its subsidiaries, as applicable) will have the right to cause us to propose a vote of our common unitholders as to whether the Series C units should be converted into common units. If our common unitholders approve the conversion, then each Series C unit will convert into a common unit. If our common unitholders do not approve the conversion within 120 days after El Paso Corporation requests the vote, then the distribution rate for the Series C units will increase to 105 percent of the common unit distribution rate. Thereafter, the Series C unit distribution rate would increase on April 30, 2004 to 110 percent of the common unit distribution rate and on April 30, 2005 to 115 percent of the common unit distribution rate. The issue price for the Series C units will be the greater of $32 per unit or the average market price of a common unit for the five trading days ending on the business day immediately preceding the closing date. If the average market price is less than $27, the San Juan acquisition may be delayed, terminated or renegotiated. The remaining balance of the purchase price will be paid in cash. We expect to fund this portion of the purchase price with a $282 million senior secured acquisition term loan and other long-term debt of $150 million. In accordance with our procedures for evaluating and valuing material acquisitions with El Paso Corporation, our Special Conflicts Committee engaged an independent financial advisor and obtained two separate fairness opinions for the acquisition of the San Juan assets and the issuance of the Series C units. The opinions we received stated the transaction and the issuance were both fair to us and our unitholders. 6

EPN Holding Assets In April 2002, EPN Holding Company, L.P., our wholly-owned subsidiary, acquired from El Paso Corporation, midstream assets located in Texas and New Mexico. The acquired assets, which we refer to as the EPN Holding assets, include: - the EPGT Texas intrastate pipeline system; - the Waha natural gas gathering and treating system located in the Permian Basin region of Texas and New Mexico; - the Carlsbad natural gas gathering system located in the Permian Basin region of New Mexico; - an approximate 42.3 percent non-operating interest in the Indian Basin natural gas processing and treating facility located in southeastern New Mexico; - a 50 percent undivided interest in the Channel natural gas pipeline system located along the Gulf coast of Texas; - the TPC Offshore natural gas pipeline system located off the Gulf coast of Texas; and - a leased interest in the Wilson natural gas storage facility located in Wharton County, Texas. The $750 million purchase price was adjusted for the assumption of $15 million of working capital related to natural gas imbalances. The net consideration of $735 million for the EPN Holding assets was comprised of the following: - $420 million of cash; - $119 million of assumed short-term indebtedness payable to El Paso Corporation, which has been repaid; - $6 million in common units; and - $190 million in assets, comprised of our Prince tension leg platform (TLP) and our nine percent Prince overriding royalty interest. To finance substantially all of the cash consideration related to this acquisition, EPN Holding entered into a limited recourse credit agreement with a syndicate of commercial banks. See Note 6 for a further discussion of the EPN Holding acquisition facility. We accounted for this acquisition as a purchase. Accordingly, an allocation of the purchase price has been assigned to the assets and liabilities acquired based upon their estimated fair value as of the acquisition date. All of the purchase price has been allocated to the EPN Holding net assets acquired. Such allocation is based on our internal evaluation of the assets. An independent appraisal of the fair value of the assets acquired is expected to be completed by the end of 2002. That appraisal will be the basis of the final allocation of the purchase price assigned to the assets and liabilities acquired. The following selected unaudited pro forma information represents our consolidated results of operations on a pro forma basis as if we acquired the EPN Holding assets on January 1, 2001:

The selected pro forma information for the quarter ended September 30, 2002 is not provided because the results of operations for the EPN Holding assets are included in the actual results of operations for the period. The selected pro forma information does not necessarily represent what our results of operations actually 7

would have been if these transactions and events had in fact occurred when assumed and are not necessarily representative of our results of operations for any future period. Hattiesburg Propane Storage In January 2002, we acquired a 3.3 million barrel propane storage business and leaching operation located in Hattiesburg, Mississippi from Suburban Propane Partners, L.P for approximately $10 million. As part of the transaction, we entered into a long-term propane storage agreement with Suburban Propane Partners for a portion of the acquired propane storage capacity. Big Thicket In August 2002, we acquired the Big Thicket assets, which consist of the Silsbee compressor station and the Big Thicket gathering system, for approximately $11 million from BP America Production Company. The Silsbee compressor station acts as a booster station for a web of area gas gathering lines. The facility has four 1,200 horsepower gas compressors that boost low pressure field gas from 45 to 950 pounds of plant inlet pressure. The Big Thicket gathering system is comprised of approximately 150 miles of 4 to 10 inch diameter pipe with throughput of approximately 22 MMcf/d. 3. PRINCE ASSETS DISPOSITION In connection with our April 2002 acquisition of the EPN Holding assets from El Paso Corporation, we sold our Prince tension leg platform (TLP) and our nine percent overriding royalty interest in the Prince Field to subsidiaries of El Paso Corporation. The results of operations for these assets have been accounted for as discontinued operations and have been excluded from continuing operations for all periods in our statements of income. Accordingly, the segment results in Note 9 reflect neither the results of operations for the Prince assets nor the related net assets held for sale. The Prince TLP was previously included in the Platform services segment and the related royalty interest was included in Other. Included in income from discontinued operations for the nine months ended September 30, 2002, were revenues of $6.7 million attributable to these disposed assets. We did not recognize any revenues related to the Prince assets during the quarter ended September 30, 2002, as these assets were sold in April 2002. Included in income from discontinued operations for the quarter and nine months ended September 30, 2001, was revenues of $1.9 million. The assets and liabilities related to the Prince assets disposition consist of the following:

In April 2002, we sold the Prince assets for $190 million and recognized a gain on the sale of $0.4 million during 2002. In conjunction with this transaction, we repaid the related outstanding $95 million principal balance under our Argo term loan. 8

4. PARTNERS' CAPITAL Cash distributions The following table reflects our per unit cash distributions to our common unitholders and the total distributions paid to our common unitholders and general partner during the nine months ended September 30, 2002:

In October 2002, we declared a cash distribution of $0.675 per common unit, $29.7 million in aggregate, for the quarter ended September 30, 2002, which we will pay on November 15, 2002, to holders of record as of October 31, 2002. In addition, we will pay distributions to our general partner of $12.0 million in respect of its general partner interest. At the current distribution rates, our general partner receives approximately 29 percent of our total cash distributions for its role as our general partner. Public offering of common units In April 2002, we issued 4,083,938 common units, which included 1,083,938 common units purchased by our general partner pursuant to its anti-dilution right under our partnership agreement, at the public offering price of $37.86 per unit. We used the net cash proceeds of approximately $149 million to reduce indebtedness under EPN Holding's acquisition facility. Also in April 2002, we issued approximately 159,000 common units at the then-current market price of $37.74 per unit to a subsidiary of El Paso Corporation as partial consideration for our acquisition of the EPN Holding assets. In addition, our general partner contributed approximately $0.6 million in cash to us in April 2002 in order to maintain its one percent capital account balance. Other In the second quarter of 2002, under the 1998 Unit Option Plan for Non-Employee Directors, we issued 5,429 restricted units with a grant price of $32.23 per unit. We have reflected the issuance of the restricted units as deferred compensation and as an increase in common units. This deferred compensation was approximately $175 thousand and was allocated 1% to our general partner and 99% to our limited partners and is being amortized over the vesting period of the restricted units, which we have estimated to be one year. The unamortized amount of our total deferred compensation as of September 30, 2002, was approximately $1.5 million. 9

5. PROPERTY, PLANT AND EQUIPMENT Our property, plant and equipment consisted of the following:

6. DEBT AND OTHER CREDIT FACILITIES Shelf registration In February 2002, our shelf registration statement, as filed with the Securities and Exchange Commission covering up to $1 billion of securities representing limited partnership interests, became effective. Credit Facility As of September 30, 2002, we had $569 million outstanding with an average interest rate of 4.46% under our $600 million credit facility with the total unused amount available. The credit facility matures in May 2004, is guaranteed by all of our subsidiaries except for our unrestricted subsidiaries and El Paso Energy Partners Finance Corporation, and is collateralized by substantially all of our assets (excluding our unrestricted subsidiaries), and our general partner's general and administrative services agreement. The credit facility, together with the EPN Holding acquisition facility, contains covenants that include restrictions on our and our subsidiaries' ability to incur additional indebtedness or liens, sell assets, make loans or investments, acquire or be acquired by other companies and amend some of our contracts, as well as requiring maintenance of certain financial ratios. As of September 30, 2002, we are not aware of anything that causes us not to be in compliance with the financial ratios and covenants contained in our credit facilities. In October 2002, we amended our $600 million credit facility and the EPN Holding acquisition facility in connection with our issuance of the senior secured term loan. The modifications included, among other things, (1) entering into a new $160 million senior secured term loan maturing in 2007; (2) designating our credit facility, the EPN Holding acquisition facility, and the senior secured term loan as "senior secured" indebtedness which is cross-collateralized on an equal basis with all of the collateral currently pledged under our credit facility and the EPN Holding acquisition facility; (3) aligning, effectively, the covenants in our credit facility and the EPN Holding acquisition facility, including eliminating the restrictions for distributing cash out of EPN Holding; and (4) terminating the $25 million revolving credit facility that was formerly part of the EPN Holding acquisition facility. Our new senior secured term loan and the EPN Holding acquisition facility are discussed below. We used the $160 million proceeds from the senior secured term loan to temporarily reduce indebtedness under our $600 million credit facility. Senior Secured Term Loan In October 2002, in connection with the amendment of our credit facilities discussed above, we obtained a $160 million senior secured term loan with a syndicate of lenders. We may elect that all or a portion of the senior secured term loan bear interest at either 2.25% plus a variable base rate (equal to the greater of the prime rate as determined by JP Morgan, the federal funds rate plus 0.5% or the CD rate as determined by JP Morgan plus 1%); or LIBOR plus 3.5%. We may, at our option, make prepayments in amounts not less 10

than $5 million. However, prepayments we make during the first year of the senior secured term loan require payment of a premium equal to one percent of the prepayment amount. The senior secured term loan is payable in semi-annual installments equal to one percent of the aggregate principal amount of the senior secured term loan for the first nine installments and the remaining balance at maturity in October 2007. The senior secured term loan is guaranteed by us and all of our material subsidiaries; and is cross-collateralized with our credit facility and our EPN Holding acquisition facility, by our general and administrative agreement, substantially all of our assets and our general partner's one percent general partner interest in us. Limited Recourse Financing EPN Holding acquisition facility -- In connection with our acquisition of the EPN Holding assets from El Paso Corporation in April 2002, EPN Holding entered into a $560 million limited recourse acquisition facility with a group of commercial banks. The acquisition facility provided a term loan of $535 million to finance the acquisition of the EPN Holding assets, and a revolving credit facility of up to $25 million to finance EPN Holding's working capital. EPN Holding's obligations under the acquisition facility are guaranteed by all of our material subsidiaries and equity interests. At the time of its acquisition, EPN Holding borrowed $535 million ($531 million, net of issuance costs) under this term loan and had $25 million available under the revolving credit facility. The EPN Holding term loan matures in April 2005. We used net proceeds of approximately $149 million from our April 2002 common unit offering, $0.6 million contributed by our general partner to maintain its one percent capital account balance and $225 million of the proceeds from our May 2002 offering of 8.5% senior subordinated notes to reduce indebtedness under the term loan. As of September 30, 2002, the outstanding balance under the term loan was $160 million bearing interest at a rate of 4.32% and there were no amounts outstanding under the acquisition facility revolving credit facility. In October 2002, as a result of amending our $600 million credit facility discussed above, the EPN Holding acquisition facility covenants were modified and the related $25 million revolving credit facility was terminated. Argo term loan -- This loan with a balance of $95 million, including current maturities, at December 31, 2001, was repaid in full in April 2002, in connection with the EPN Holding asset acquisition. Senior Subordinated Notes In May 2002, we issued $230 million in aggregate principal amount of 8.5% Senior Subordinated Notes due June 2011. The Senior Subordinated Notes were issued for $234.6 million (proceeds of approximately $230 million, net of issuance costs). We used proceeds of $225 million to reduce indebtedness under our EPN Holding acquisition facility and the remainder for general partnership purposes. In August 2002, we filed a registration statement for an offer to exchange these notes for registered debt securities with identical terms. The registration statement is currently under review by the SEC. Other credit facilities Poseidon Oil Pipeline Company, L.L.C., an unconsolidated affiliate, is party to a $185 million credit agreement under which it has outstanding obligations that may restrict its ability to pay distributions to its owners. In January 2002, Poseidon entered into a two-year interest rate swap agreement to fix the interest rate at 4.99% through January 2004 on $75 million of the $150 million outstanding on its credit facility. As of September 30, 2002, the remaining $75 million was at an average floating interest rate of 3.38%. In August 2002, Deepwater Gateway, our joint venture that owns the Marco Polo TLP, obtained a $155 million project loan at a variable interest rate from a group of commercial lenders to finance a substantial portion of the cost to construct the Marco Polo TLP and related facilities. Upon completion of the construction, the project loan will convert into a term loan, subject to the terms of the loan agreement. The loan is collateralized by substantially all of Deepwater Gateway's assets. If Deepwater Gateway defaults on its payment obligations under the loan, we would be required to pay to the lenders all distributions we or any of 11

our subsidiaries had received from Deepwater Gateway up to $22.5 million. As of September 30, 2002, Deepwater Gateway had no amounts outstanding under the project loan and had not paid us or any of our subsidiaries any distributions. If Deepwater Gateway had amounts outstanding as of September 30, 2002, the average interest rate would have been 3.56%. 7. COMMITMENTS AND CONTINGENCIES Legal Proceedings Grynberg. In 1997, we, along with several subsidiaries of El Paso Corporation, 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. Will Price (formerly Quinque). We have also been named defendants 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 plaintiff in this case seeks certification of a nationwide class of gas working interest owners and gas royalty owners to recover royalties that the plaintiff contends 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 has been filed and we have filed our response. Our Argo L.L.C. subsidiary received a claim from its contractor related to our recently completed Prince TLP. The contractor received a request for additional payments from its subcontractor as a result of variation orders and is seeking to pass these costs along to Argo. After negotiations, the contractor, the subcontractor and Argo agreed upon a settlement in July 2002. This settlement did not have a material adverse effect on our financial position, results of operations or cash flow. Under the terms of our agreement with El Paso Corporation pursuant to which we acquired the EPN Holding 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 gas in areas of western Texas related to an asset now owned by EPN Holding. 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 are set for November 2002. Also, EPGT Texas Pipeline L.P., now owned by EPN Holding, is involved in litigation with the City of Edinburg concerning the City's claim that EPGT 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 EPGT Texas and is now owned by Southern Union Gas Company. An adverse judgment against Southern Union and EPGT Texas was rendered in Hidalgo County State District court in December 1998 and found a breach of 12

contract, and held both EPGT 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 EPGT Texas and Southern Union's entities that were not parties to the contract with the City. EPGT Texas has appealed this case to the Texas Supreme Court seeking reversal of the judgment rendered against EPGT Texas. The City seeks a remand to the trial court of its claim of tortious interference against EPGT Texas. Briefs have been filed and oral arguments are set for November 2002. In December 2000, a 30-inch natural gas pipeline jointly owned by El Paso Energy Intrastate, now owned by EPN Holding, and Houston Pipe Line Company LP ruptured in Mont Belvieu, Texas, near Baytown, resulting in substantial property damage and minor physical injury. El Paso Energy Intrastate is the operator of the pipeline. In December 2000 a lawsuit was 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, El Paso Energy Intrastate has agreed to assume the defense of and to indemnify Houston Pipe Line Company. In September 2002, an agreement was reached to settle the claims of two plaintiffs (including one of the insurers). The discovery phase of the lawsuit is proceeding and trial is expected in early 2003. The City of Corpus Christi, Texas ("City") is alleging that EPGT Texas and various Coastal entities owe it monies for past obligations under City ordinances that propose to tax EPGT 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 EPGT Texas pipe at issue has been using the rights-of-way since the 1960's. In addition, the City demands that EPGT Texas agree to a going-forward consent agreement in order for EPGT Texas pipe and Coastal to have the right to remain in City rights-of-way. In addition to the above matters, we and our subsidiaries and affiliates are named defendants in numerous lawsuits and governmental proceedings that arise in the ordinary course of our business. For each of our outstanding legal matters, we evaluate the merits of the case, our exposure to the matter, possible legal or settlement strategies and the likelihood of an unfavorable outcome. If we determine that an unfavorable outcome is probable and can be estimated, we will establish the necessary accruals. As of September 30, 2002, we had no reserves for our legal matters. While the outcome of our outstanding legal matters cannot be predicted with certainty, based on information known to date, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. As new information becomes available or relevant developments occur, we will establish accruals as appropriate. The impact of these changes may have a material effect on our results of operations. Environmental Each of our operating segments is subject to extensive federal, state, and local laws and regulations governing environmental quality and pollution control. These laws and regulations are applicable to each segment and require us to remove or remedy the effect on the environment of the disposal or release of specified substances at current and former operating sites. As of September 30, 2002, we had a reserve of approximately $21 million for remediation costs expected to be incurred over time associated with mercury meters. We assumed this liability in connection with our April 2002 acquisition of the EPN Holding assets. In addition, we expect to make capital expenditures for environmental matters of approximately $10 million in the aggregate for the years 2003 through 2007, primarily to comply with clean air regulations. While the outcome of our outstanding environmental matters cannot be predicted with certainty, based on the information known to date and our existing accruals, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. It is possible that new information or future developments could require us to reassess our potential exposure related to environmental matters. It is also possible that other developments, such as increasingly strict environmental laws and regulations and claims for damages to property, employees, other persons and the 13

environment resulting from our current or past operations, could result in substantial costs and liabilities in the future. As new information becomes available, or relevant developments occur, we will review our accruals and make any appropriate adjustments. The impact of these changes may have a material effect on our results of operations. Rates and Regulatory Matters Marketing Affiliate NOPR. In September 2001, the Federal Energy Regulatory Commission (FERC) issued a Notice of Proposed Rulemaking (NOPR). The NOPR proposes to apply the standards of conduct governing the relationship between interstate pipelines and marketing affiliates to all energy affiliates. Since our High Island Offshore System (HIOS) and Petal Gas Storage facility are interstate facilities as defined by the Natural Gas Act, the proposed regulations, if adopted by FERC, would dictate how HIOS and Petal conduct business and interact with all of our energy affiliates and El Paso Corporation's energy affiliates. In December 2001, we filed comments with the FERC addressing our concerns with the proposed rules. A public hearing was held in May 2002, providing an opportunity to comment further on the NOPR. Following the conference, additional comments were filed by us. At this time, we cannot predict the outcome of the NOPR, but adoption of the regulations in the form proposed would, at a minimum, place additional administrative and operational burdens on us. If the standards of conduct NOPR is adopted by the FERC, we will be required to functionally separate our HIOS and Petal interstate facilities from our other entities. Under the proposed rule, we would be required to dedicate employees to manage and operate our interstate facilities independently from our other non-jurisdictional facilities. This employee group would be required to function independently and would be prohibited from communicating non-public transportation information to affiliates. Separate office facilities and systems would be necessary because of the requirement to restrict affiliate access to interstate transportation information. The NOPR also limits the sharing of employees and officers with non-regulated entities. Because of the loss of synergies and shared employee restrictions, a disposition of the interstate facilities may be necessary for us to effectively comply with the rule. At this time, we cannot predict the outcome of this NOPR. Negotiated Rate NOI. In July 2002, the FERC issued a Notice of Inquiry (NOI) that seeks comments regarding its 1996 policy of permitting pipelines to enter into negotiated rate transactions. The FERC is now reviewing whether or not a pipeline's "recourse rate" (its cost of service based rate) continues to safeguard against a pipeline exercising market power, as well as other issues related to negotiated rate programs. Cash Management NOPR. In August 2002, the FERC issued a NOPR requiring that all cash management or money pool arrangements between a FERC regulated subsidiary and a non-FERC regulated parent must be in writing, and set forth: the duties and responsibilities of cash management participants and administrators; the methods of calculating interest and for allocating interest income and expenses; and the restrictions on deposits or borrowings by money pool members. The NOPR also requires specified documentation for all deposits into, borrowings from, interest income from, and interest expenses related to, these arrangements. Finally, the NOPR proposes that as a condition of participating in a cash management or money pool arrangement, the FERC regulated entity must maintain a minimum proprietary capital balance of 30 percent, and the FERC regulated entity and its parent must maintain investment grade credit ratings. In August 2002 comments were filed. Representatives of companies from the gas and electric industries participated on a panel and uniformly agreed that the proposed regulations should be revised substantially and that the proposed capital balance and investment grade credit rating requirements would be excessive. At this time, we cannot predict the outcome of this NOPR. Also in August 2002, FERC's Chief Accountant issued an Accounting Release, to be effective immediately, providing guidance on how companies should account for money pool arrangements and the types of documentation that should be maintained for these arrangements. However, the Accounting Release did not address the proposed requirements that the FERC regulated entity maintain a minimum proprietary capital balance of 30 percent and that the entity and its parent have investment grade credit ratings. Requests for rehearing were filed in August 2002. The FERC has not yet acted on the rehearing requests. 14

If the cash management NOPR is adopted by the FERC, our HIOS and Petal interstate facilities will no longer be permitted to participate in a money pool or cash management program. As a result, more frequent distributions or equity contributions may be needed in anticipation of monthly cash flow requirements for those interstate facilities. Also, separate credit facilities and resources may be required to support the capital and day-to-day activities for the interstate facilities separate from other of our subsidiaries and our primary bank accounts. Other Regulatory Matters. Our HIOS system is also subject to the jurisdiction of the FERC in accordance with the Natural Gas Act of 1938 and the Natural Gas Policy Act of 1978. HIOS operates under a separate FERC approved tariff that governs its operations, terms and conditions of service, and rates. We are obligated to file a new rate case for our HIOS system no later than December 31, 2002. In June 2002, Petal Gas Storage filed with the FERC a certificate application to add additional gas storage capacity to Petal's storage system. The filing included a new storage cavern with a working gas capacity of 5 Bcf, the conversion and enlargement of an existing subsurface brine storage cavern to a gas storage cavern with a working capacity of 3 Bcf and related surface facilities, natural gas, water and brine transmission lines. In December 1999, EPGT Texas filed a petition with the FERC for approval of its rates for interstate transportation service. In June 2002, the FERC issued an order that required revisions to EPGT Texas' proposed rates. It also ordered refunds to customers for the difference, if any, between the originally proposed levels and the revised rates ordered by the FERC. The changes ordered by the FERC involve reductions to rate of return, depreciation rates and revisions to the proposed rate design, including a requirement to separately state rates for gathering service. We believe the amount of any rate refund would be minimal since, as provided for in our tariff, we were not charging our customers at the maximum rate. In July 2002, EPGT Texas requested rehearing on certain issues raised by the FERC's order, including the ordered changes to rate design and depreciation rates, and the requirement to separately state a gathering rate. Falcon Gas Storage also requested late intervention and rehearing of the order. Falcon asserts that EPGT Texas' imbalance penalties and terms of service preclude third parties from offering imbalance management services. EPGT Texas' request for rehearing has been granted and is pending before the FERC. While the outcome of all of our rates and regulatory matters cannot be predicted with certainty, based on information known to date, we do not expect the ultimate resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. As new information becomes available or relevant developments occur, we will review our accruals and make any appropriate adjustments. The impact of these changes may have a material effect on our results of operations. Other Matters As a result of current circumstances generally surrounding the energy sector, the creditworthiness of several industry participants has been called into question. As a result of these general circumstances, we have established an internal group to monitor our exposure to and determine, as appropriate, whether we should request prepayments, letters of credit or other collateral from our counterparties. If these general conditions worsen and, as a result, several industry participants file for Chapter 11 bankruptcy protection, it could have a material adverse effect on our financial position, results of operations or cash flows. 8. ACCOUNTING FOR HEDGING ACTIVITIES A majority of our commodity purchases and sales, which relate to sales of oil and natural gas associated with our production operations, purchases and sales of natural gas associated with our El Paso Intrastate Alabama (EPIA) pipeline and sales of liquids associated with our interest in the Indian Basin processing plant, are at spot market or forward market prices. We use futures, forward contracts, and swaps to limit our exposure to fluctuations in the commodity markets and allow for a fixed cash flow stream from these activities. In August 2002, we entered into a derivative financial instrument to hedge our exposure during 2003 relating to gathering activities for changes in natural gas prices in the San Juan Basin in anticipation of our proposed acquisition of the San Juan assets. The derivative is a financial swap on 30,000 MMBtu per day 15

whereby we receive a fixed price of $3.525 per MMBtu and pay a floating price based on the San Juan index. We are accounting for this derivative under mark-to-market accounting since it does not qualify for hedge accounting under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. As of September 30, 2002, the fair value of this derivative was a $1.0 million liability and we recognized this $1.0 million loss in the margin of our Natural gas pipelines and plants segment. Once the proposed acquisition of the San Juan assets is completed, we expect to designate this derivative as a cash flow hedge under SFAS 133. At September 30, 2002, in connection with our EPIA operations, we have fixed price contracts with specific customers for the sale of predetermined volumes of natural gas for delivery over established periods of time. We entered into cash flow hedges in 2001 and 2002 to offset the risk of increasing natural gas prices. As of September 30, 2002, the fair value of these cash flow hedges was an asset of approximately $49 thousand. For the nine months ended September 30, 2002, the majority of these cash flow hedges expired and we reclassified a loss of $1.4 million from accumulated other comprehensive income to earnings. No ineffectiveness exists in our hedging relationship because all purchase and sale prices are based on the same index and volumes as the hedge transaction. We estimate the entire amount will be reclassified from accumulated other comprehensive income to earnings over the next nine months. Starting in April 2002, in connection with our EPN Holding acquisition, we have swaps in place for our interest in the Indian Basin processing plant to hedge the price received for the sale of natural gas liquids. As of September 30, 2002, the fair value of these cash flow hedges was a $126 thousand liability resulting in an unrealized loss of $126 thousand. We do not expect any ineffectiveness in our hedging relationship since all sale prices are based on the same index as the hedge transaction. We estimate the entire amount will be reclassified from accumulated other comprehensive income to earnings over the next three months. In January 2002, Poseidon entered into a two-year interest rate swap agreement to fix the interest rate on $75 million of its $150 million variable rate revolving credit facility at 4.99% over the life of the swap. As of September 30, 2002, the fair value of its interest rate swap was a liability of $1.6 million resulting in accumulated other comprehensive loss of $1.6 million. We included our 36 percent share of this liability of $0.6 million as a reduction of our investment in Poseidon and as loss in accumulated other comprehensive income which we estimate will be reclassified to earnings proportionately over the next 15 months. Additionally, we have recognized in income our 36 percent share of Poseidon's realized loss of $0.9 million for the nine months ended September 30, 2002, or $0.3 million, through our earnings from unconsolidated affiliates. Our counterparties for EPIA and Indian Basin hedging activities are El Paso Merchant Energy and El Paso Field Services, affiliates of our general partner. We do not require collateral and do not anticipate non-performance by our counterparties. The counterparty for Poseidon's hedging activity is Credit Lyonnais. Poseidon does not require collateral and does not anticipate non-performance by the counterparty. The counterparty for our San Juan hedging activity is J. Aron and Company, a subsidiary of Goldman Sachs. We do not require collateral and do not anticipate non-performance by our counterparty. 9. SEGMENT INFORMATION In light of our expectation of acquiring additional natural gas pipeline and processing assets, effective January 1, 2002, we revised and renamed our business segments to reflect the change in composition of our operations as discussed below. We have segregated our business activities into four distinct operating segments: - Natural gas pipelines and plants; - Oil and NGL logistics; - Natural gas storage; and - Platform services. 16

In October 2001, we acquired the Chaco processing plant and reflected the operations of this asset in our Oil and NGL logistics segment. With the change in our segments, we moved the Chaco processing plant to our Natural gas pipelines and plants segment. As a result of our sale of the Prince TLP and our nine percent overriding royalty interest in the Prince Field in April 2002, the results of operations from these assets are reflected as discontinued operations in our statements of income for all periods presented. Accordingly, the segment results reflect neither the results of operations for the Prince assets nor the related assets held for sale. Beginning in 2002, operations from our oil and natural gas production activities are reflected in Other. We have restated the prior periods, to the extent practicable, in order to conform to our current business segment presentation. The restated results of operations for the quarter and nine months ended September 30, 2001, are not necessarily indicative of the results which would have been achieved had the revised business structure been in effect during the period. Each of our segments are business units that offer different services and products. They are managed separately, as each requires different technology and marketing strategies. We measure segment performance using performance cash flows, or an asset's ability to generate cash flow. Performance cash flows are used as a supplemental financial measurement in the evaluation of our businesses and should not be considered as an alternative to net income as an indicator of our operating performance or as an alternative to cash flows from operating activities as a measure of liquidity. Performance cash flows may not be a comparable measurement among different companies. Following are results as of and for the periods ended September 30: QUARTER ENDED SEPTEMBER 30, 2002

QUARTER ENDED SEPTEMBER 30, 2001

- ---------- (1) Represents predominately our oil and natural gas production activities as well as intersegment eliminations. 17

RECONCILIATION OF PERFORMANCE CASH FLOWS BY SEGMENT

- --------------- (1) We finance our activities and evaluate our minority interest at the consolidated level and therefore we do not allocate interest and debt expense among our segments. (2) Performance cash flows (or Adjusted EBITDA) is determined by taking EBIT and adding or subtracting, as appropriate, cash distributions from unconsolidated affiliates; depreciation, depletion and amortization; earnings from unconsolidated affiliates; gains and losses on asset sales; and other nonrecurring items. 19

RECONCILIATION OF PERFORMANCE CASH FLOWS BY SEGMENT

10. INVESTMENTS IN UNCONSOLIDATED AFFILIATES We hold investments in various affiliates which we account for using the equity method of accounting. In October 2001, we acquired the remaining 50 percent of Deepwater Holdings, L.L.C. that we did not already own. Following this transaction, Deepwater Holdings has been consolidated in our financial statements from the acquisition date. Summarized financial information for these investments are as follows: NINE MONTHS ENDED SEPTEMBER 30, 2002 (IN THOUSANDS)

NINE MONTHS ENDED SEPTEMBER 30, 2001 (IN THOUSANDS)

- ---------- (1) We recorded adjustments primarily for differences from estimated year end earnings reported in our Annual Report on Form 10-K and actual earnings reported in the audited annual reports of our unconsolidated affiliates. For the nine months ended September 30, 2001, we recorded an additional adjustment relating to the sale of Stingray Pipeline Company, U-T Offshore System (UTOS) and West Cameron. The loss on these sales was not allocated proportionately with Deepwater Holdings' ownership percentages because the capital contributed by us was a larger amount of capital at the formation and therefore we were allocated a larger portion of the loss. Our total share of the loss relating to these sales was approximately $14 million. (2) Divested Investments includes Manta Ray Offshore Gathering Company, L.L.C. and Nautilus Pipeline Company, L.L.C. In January 2001, we sold our 25.67% interest in Manta Ray Offshore and our 25.67% interest in Nautilus. 21

Deepwater Gateway/Marco Polo Project In June 2002, we formed Deepwater Gateway, L.L.C., a 50/50 joint venture with Cal Dive International Inc., to construct and install the Marco Polo TLP. The total cost of the project is estimated to be $206 million or approximately $103 million for our share. As of September 30, 2002, we have contributed $27 million to Deepwater Gateway. Arizona Gas Storage, L.L.C./Copper Eagle Project In June 2002, we acquired El Paso Corporation's effective 30 percent interest in a natural gas storage facility development project located near Phoenix, Arizona. 11. RELATED PARTY TRANSACTIONS Our transactions with related parties and affiliates are as follows:

For the quarters ended September 30, 2002 and 2001, revenues received from related parties consisted of approximately 45% and 35% of our total revenue. For the nine months ended September 30, 2002 and 2001, revenues received from related parties consisted of approximately 43% and 26% of our total revenue. There have been no changes to our related party relationships, except as described below, from those described in Note 9 of our audited financial statements filed in our current report on Form 8-K/A dated July 19, 2002. 22

Revenues received from related parties EPN Holding Assets. Our revenues from related parties increased in 2002 as a result of our EPN Holding transaction in which we acquired gathering, transportation and processing contracts with affiliates of our general partner. For the quarter and nine months ended September 30, 2002, we received $21.8 million and $46.1 million from El Paso Merchant Energy North America Company, $10.2 million and $19.6 million from El Paso Field Services and $1.4 million and $2.8 million from El Paso Production Company. Expenses paid to related parties Cost of natural gas. Our cost of natural gas paid to related parties increased in 2002 as a result of our EPN Holding transaction in which we acquired contracts with affiliates of our general partner. For the quarter and nine months ended September 30, 2002, we had natural gas imbalance settlement expenses of $0.1 million and $0.3 million from Tennessee Gas Pipeline Company and $0.1 million for the nine months ended September 30, 2002 from El Paso Merchant Energy North America Company. Operating expenses. Our operating expense paid to related parties increased in 2002 as a result of our EPN Holding transaction in which we acquired operating agreements with El Paso Field Services. For the quarter and nine months ended September 30, 2002, we had operating expenses of $6.3 million and $11.4 million. Under a general and administrative services agreement between subsidiaries of El Paso Corporation and us, a fee of approximately $0.8 million per month was charged to our general partner, and accordingly, to us, which is intended to approximate the amount of resources allocated by El Paso Corporation and its affiliates in providing various operational, financial, accounting and administrative services on behalf of our general partner and us. In April 2002, in connection with our acquisition of EPN Holding assets, our general and administrative services agreement was extended to December 31, 2005, and the fee increased to approximately $1.6 million per month. We believe this fee approximates the actual costs incurred. Other Matters In addition to the related party transactions discussed above, pursuant to the terms of many of the purchase and sale agreements we have entered into with various entities controlled directly or indirectly by El Paso Corporation, we have been indemnified for potential future liabilities, expenses and capital requirements above a negotiated threshold. Specifically, an indirect subsidiary of El Paso Corporation has indemnified us for specific litigation matters to the extent the ultimate resolutions of these matters result in judgments against us. For a further discussion of these matters see Note 7, Commitments and Contingencies, Legal Proceedings. Some of our agreements obligate certain indirect subsidiaries of El Paso Corporation to pay for capital costs related to maintaining assets which were acquired by us, if such costs exceed negotiated thresholds. We do not believe these thresholds will be exceeded. We have made no such claims for reimbursement to date and none are contemplated to be made at this time. We have also entered into capital contribution arrangements with regulated pipelines owned by El Paso Corporation in the past, and will most likely do so in the future, as part of our normal commercial activities in the Gulf of Mexico. Regulated pipelines often contribute capital toward the construction costs of gathering facilities owned by others which are connected to their pipelines. We have, or plan to have, agreements with ANR Pipeline Company and Tennessee Gas Pipeline Company under which we will receive a total of approximately $25 million of capital toward the construction of gathering pipelines to the Marco Polo, Red Hawk and Medusa discoveries, payable over the next eighteen months. 23

The following table provides summary data categorized by our related parties:

- ---------- (1) We sold our interest in Manta Ray Offshore in January 2001 in connection with El Paso Corporation's acquisition of The Coastal Corporation. (2) In January 2001, Deepwater Holdings sold its Stingray and West Cameron subsidiaries. In April 2001, Deepwater Holdings sold its UTOS subsidiary. In October 2001, we acquired the remaining 50 percent of Deepwater Holdings, and as a result of this transaction, Deepwater Holdings is consolidated in our financial statements from the acquisition date and our agreement with Deepwater Holdings terminated. 24

At September 30, 2002, and December 31, 2001, our accounts receivable due from related parties was $46.7 million and $23.0 million. At September 30, 2002 and December 31, 2001, our accounts payable due to related parties was $27.6 million and $10.1 million. Our accounts receivable due from related parties consisted of the following as of:

Our accounts payable due to related parties consisted of the following as of:

In connection with the sale of our Gulf of Mexico assets in January 2001, El Paso Corporation agreed to make quarterly payments to us of $2.25 million for three years beginning March 2001 and $2 million in the first quarter of 2004. The present value of the amounts due from El Paso Corporation were classified as follows:

12. GUARANTOR FINANCIAL INFORMATION On May 1, 2001, we purchased our general partner's 1.01 percent non-managing interest owned in twelve of our subsidiaries for $8 million. As a result of this acquisition, all of our subsidiaries, but not our equity investees, are wholly owned by us. As of September 30, 2002, our revolving credit facility is guaranteed by each of our subsidiaries (excluding our EPN Holding subsidiaries) and is collateralized by our general and administrative agreement, substantially all of our assets, and our general partner's one percent general partner interest. In addition, all of our senior subordinated notes are jointly, severably, fully and unconditionally guaranteed by all of our subsidiaries except EPN Holding's subsidiaries. As of September 30, 2002, the EPN Holding acquisition facility is guaranteed by all of EPN Holding's subsidiaries and by EPN Holding I, L.P. and EPN GP Holding L.L.C., our unrestricted subsidiaries that own the equity interests in EPN Holding, and is collateralized by substantially all of the assets of EPN Holding and the guarantors. In October 2002, we rearranged our credit facilities and entered into a $160 million senior secured term loan. As a result of that rearrangement our credit facility, the EPN Holding acquisition facility and the senior secured term loan are all guaranteed by all of our material subsidiaries. We are providing the following condensed consolidating financial information of us (as the Issuer) and our subsidiaries as if our current organizational structure were in place for all periods presented. The consolidating eliminations column on our balance sheets eliminate our investment in consolidated subsidiaries, intercompany payables and receivables and other transactions between subsidiaries. Non-guarantor subsidiaries as of and for the quarter and nine months ended September 30, 2002, consisted of our EPN Holding subsidiaries, which own the EPN Holding assets and the equity interests in EPN Holding, and our subsidiary that owns our interest in the Copper Eagle project. Non-guarantor subsidiaries for all other periods consisted of Argo and Argo I which owned the Prince TLP. As a result of our disposal of the Prince TLP and our related overriding royalty interest in April 2002, the results of operations and net book value of these assets are reflected as discontinued operations in our statements of income and assets held for sale in our balance sheets and Argo and Argo I became guarantor subsidiaries.

13. NEW ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED We continually monitor the activities of the various rule makers involved in developing general accepted accounting principles for use in the United States. At this time, there are several new accounting pronouncements that have recently been issued, but are not yet adopted, which will impact our accounting when these rules become effective. The new rules not yet adopted that will have an impact on our accounting policies are discussed below. Accounting for Asset Retirement Obligations In August 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 143, Accounting for Asset Retirement Obligations. This statement requires companies to record a liability for the estimated retirement and removal costs of assets used in their business. The liability is discounted to its present value, and the related asset value is increased by the amount of the resulting liability. Over the life of the asset, the liability will be accreted to its future value and eventually extinguished when the asset is taken out of service. Capitalized retirement and removal costs will be depreciated over the useful life of the related asset. The provisions of this statement are effective for fiscal years beginning after June 15, 2002. We are currently evaluating the effects of this pronouncement. Reporting Gains and Losses from the Early Extinguishment of Debt In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections. This statement addresses how to report gains or losses resulting from the early extinguishment of debt. Previously, any gains or losses were reported as an extraordinary item. Upon adoption of SFAS No. 145, an entity will be required to evaluate whether the debt extinguishment is truly extraordinary in nature, in accordance with Accounting Principles Board Opinion No. 30. If the entity routinely extinguishes debt early, the gain or loss should be included in income from continuing operations. This statement is effective for our 2003 year-end reporting. Accounting for Costs Associated with Exit or Disposal Activities In July 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. This statement requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. Examples of costs covered by this guidance include lease termination costs and certain employee severance costs that are associated with a restructuring, discontinued operation, plant closing, or other exit or disposal activity. The provisions of this statement are effective for fiscal years beginning after December 31, 2002. The provisions of this statement will impact any exit or disposal activities that we initiate after January 1, 2003. 33

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The information contained in Item 2 updates, and you should read it in conjunction with, information disclosed in Part II, Items 7, 7A and 8, in our Annual Report on Form 10-K for the year ended December 31, 2001, in addition to the interim financial statements and notes presented in Item 1 of this Quarterly Report on Form 10-Q. LIQUIDITY AND CAPITAL RESOURCES Since the fourth quarter of 2001, a number of developments in our businesses and industry have significantly impacted our operations and liquidity, as well as the United States debt and equity markets. Our ability to execute our growth strategy and complete our current projects is dependent upon our ability to access the capital necessary to fund our projects and acquisitions. How much we actually spend will depend on our success with capital raising efforts, including the formation of joint ventures to share costs and risks. At this time, we believe our access to capital resources is sufficient to meet the demands of our current and future operating growth needs. Although we intend to make the forecasted project expenditures, we may adjust the timing and amounts of the projected expenditures as necessary to adapt to changes in the capital markets. FORECASTED EXPENDITURES Our management estimates capital expenditures based upon current expectations; however, estimates may change due to factors out of our control, such as weather related issues or changes in supplier prices. Further, estimates may change as a result of decisions made at a later date, such as scope changes or decisions to take on additional partners. The table below depicts our estimate of expenditures on projects, acquisitions, operating lease payments and debt repayments for the twelve month period ending September 30, 2003. These expenditures are net of anticipated financings, contributions in aid of construction and contributions from joint venture partners. Actual results may vary from these projections.

CAPITAL RESOURCES During the third quarter of 2002, the United States equity and debt markets remained volatile due to the announcements of several SEC investigations, corporate scandals, and business failures. With the collapse of 34

former energy giant Enron, the prospect for war with Iraq and significant negative media coverage, the energy sector has experienced market volatility, primarily by those companies involved in energy marketing. The flight of investors from the equity markets to "safer havens" has prevented all but the most stalwart of companies from tapping the debt and equity markets for raising capital. Additionally, numerous energy companies have experienced downgrades in their debt securities by Moody's Investors Service (Moody's) and Standard & Poor's (S&P), two of the largest debt rating agencies, effectively reducing the ability of many energy companies from raising operating capital from the credit markets. Although current economic conditions are unfavorable, we expect the economy to stabilize and improve over the next six to twelve months, which should also produce stability in the credit and equity markets and provide for increased access to additional sources of capital. Despite the difficulty in the credit and equity markets, we successfully raised $160 million through the issuance of our senior secured term loan to a syndicate of lenders following the end of the third quarter. We continue to reap the benefits of our solid balance sheet and operating performance as evidenced by Moody's and S&P's recent affirmation of our credit ratings. Finally, the continued strong operating performance of our current assets has enabled us to increase our borrowing capacity under our financial covenants, effectively increasing our ability to access cash for executing our operating and growth objectives. In October 2002, we also amended our $600 million credit facility and the EPN Holding acquisition facility to among other things: (1) enter into the $160 million senior secured term loan discussed above; (2) designate all of the above loans as "senior secured" indebtedness, which is cross-collateralized with all of the collateral currently pledged under our credit facility and the EPN Holding acquisition facility; (3) align, effectively, the covenants in our credit facility and the EPN Holding acquisition facility; and (4) terminate the $25 million working capital revolver that was formerly part of the EPN Holding acquisition facility. These credit facilities contain covenants that include restrictions on our and our subsidiaries' ability to incur additional indebtedness or liens, sell assets, make loans or investments, acquire or be acquired by other companies and amend some of our contracts, as well as requiring maintenance of certain financial ratios. As of September 30, 2002, we are not aware of anything that causes us not be in compliance with the financial ratios and covenants contained in our credit agreements. We have three features contained in our debt instruments described as ratings triggers. Two of these features provide us, rather than creditors, with certain rights in the event that our credit ratings change to an investment grade level. These triggers are contained in our: - indenture governing our $480 million 8 1/2% Senior Subordinated Notes due 2011 ($230 million of which were issued in May 2002), where many covenants will be suspended in the event we achieve an investment grade credit rating; and - $600 million credit facility, where we will receive a 38 to 50 basis point reduction in our interest rate in the event we achieve an investment grade credit rating. Additionally, with respect to our $160 million senior secured term loan, if, at any time, our senior, long-term unsecured debt rating (a) issued by Standard & Poor's is less than BB+ or (b) issued by Moody's is less than Ba1, or our senior secured debt rating issued by Moody's is less than Ba1, the interest rate on that term loan increases by one percent. There are no other trigger features or mechanisms in any of our debt instruments or commercial arrangements. DEBT REPAYMENT AND OTHER OBLIGATIONS See Part I, Financial Information, Note 6, for a detailed discussion of our debt obligations. 35

The following table presents the timing and amounts of our debt payment and other obligations for the years following September 30, 2002, that we believe could affect our liquidity (in millions):

- --------------- (1) The senior secured term loan was funded in October 2002, as more fully discussed in Note 6 of the financial statements included in Item 1 and in Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations. SERIES B PREFERENCE UNITS In August 2000, we issued $170 million of Series B preference units to acquire the natural gas storage businesses of Crystal Gas Storage, Inc. These preference units are non-voting and have rights to income allocations on a cumulative basis, compounded semi-annually at an annual rate of 10%. We are not obligated to pay cash distributions on these units until 2010. After September 2010, the rate will increase to 12% and preference income allocation after 2010 will be required to be paid on a current basis; accordingly, after September 2010, we will not be able to make distributions on our common units unless all unpaid accruals occurring after September 2010 on our then-outstanding Series B preference units have been paid. These preference units contain no mandatory redemption obligation, but may be redeemed at our option at any time. In October 2001, we redeemed 44,608 of the Series B preference units for $50 million liquidation value, including accrued distributions of approximately $5.4 million, bringing the total number of units outstanding to 125,392. As of September 30, 2002, the liquidation value of the outstanding Series B preference units was approximately $154 million. CASH FROM OPERATING ACTIVITIES Net cash provided by operating activities was $138.5 million for the nine months ended September 30, 2002, compared to $89.3 million for the same period in 2001. The increase was attributable to operating cash flows from our acquisitions of the Chaco plant in October 2001, the remaining 50 percent interest in Deepwater Holdings that we did not already own in October 2001, and the EPN Holding assets in April 2002. This increase was partially offset by lower cash distributions in 2002 from our unconsolidated affiliate, Poseidon. CASH FROM INVESTING ACTIVITIES Net cash used in investing activities was approximately $726.4 million for the nine months ended September 30, 2002. Our investing activities include our April 2002 purchase of the EPN Holding assets, our August 2002 purchase of the Big Thicket assets and capital expenditures related to the expansion of our Petal natural gas storage facility. Further contributing to the expenditures were additions to investments from unconsolidated affiliates relating to our Marco Polo project and our Copper Eagle project. These expenditures were partially offset by proceeds of $5.5 million from the March 2002 sale of our Buffalo Treating Facility to 36

El Paso Production Company and the April 2002 sale of our Prince TLP and nine percent Prince overriding royalty interest to subsidiaries of El Paso Corporation. The Prince assets sales are reflected as net cash provided by investing activities of discontinued operations in our statement of cash flows. CASH FROM FINANCING ACTIVITIES Net cash provided by financing activities was approximately $597.0 million for the nine months ended September 30, 2002. During 2002, our cash provided by financing activities included the issuances of long-term debt and common units, as well as borrowings under our credit facility and EPN Holding acquisition facility. Cash used in our financing activities included repayments on our EPN Holding acquisition facility, Argo term loan, our credit facility and other financing obligations, as well as distributions to our partners. RECENT DEVELOPMENTS We often enter into transactions with El Paso Corporation and its subsidiaries to acquire or sell assets, and have instituted specific procedures for evaluating and valuing these transactions. Before we consider entering into a material transaction with El Paso Corporation or any of its subsidiaries, we determine that the proposed transaction (1) would comply with the requirements under our indentures and credit agreements, (2) would comply with substantive law, and (3) would be fair to us and our limited partners. In addition, our general partner's board of directors utilizes a Special Conflicts Committee comprised solely of independent directors. This committee: - evaluates and, where appropriate, on occasion negotiates certain aspects of the proposed transaction; - engages an independent financial advisor and independent legal counsel to assist with its evaluation of the proposed transaction; and - determines whether to approve and recommend the proposed transaction. We will only consummate any proposed material transaction with El Paso Corporation if, following our evaluation of the transaction, the Special Conflicts Committee approves and recommends the proposed transaction. ACQUISITIONS Proposed Acquisition of the San Juan Assets In July 2002, we entered into a letter of intent with El Paso Corporation, the indirect parent of our general partner, to acquire for $782 million El Paso Corporation's natural gas gathering system located in the San Juan Basin of New Mexico, including El Paso Corporation's remaining interests in the Chaco cryogenic natural gas processing plant; NGL transportation and fractionation assets located in Texas; and an oil and natural gas gathering system located in the deeper water regions of the Gulf of Mexico, referred to collectively as the San Juan assets. As part of this transaction, El Paso Corporation will be required to repurchase the Chaco processing plant from us for $77 million in October 2021, and at that time, we will have the right to lease the plant from El Paso Corporation for a period of ten years with the option to renew the lease annually thereafter. With the close of this transaction, the monthly fee under our general and administrative services agreement with subsidiaries of El Paso Corporation will increase by $1.3 million, bringing our total monthly fee to $2.9 million. The purchase price of $782 million is subject to adjustments primarily for working capital and capital expenditures. The following is a description of the San Juan assets: - The assets located in the San Juan Basin include: - approximately 5,300 miles of natural gas gathering pipelines, known as the San Juan gathering system, with capacity of over 1.1 Bcf/d connected to approximately 9,500 wells producing natural gas from the San Juan Basin located in northwest New Mexico and southwest Colorado; - approximately 250,000 horsepower of compression; - the 58 MMcf/d Rattlesnake CO(2) treating facility; 37

- a 50% interest in Coyote Gas Treating, L.L.C., the owner of a 250 MMcf/d treating facility; and - the remaining interests in the Chaco cryogenic natural gas processing plant that we do not already own and the price risk management positions related to this facility's operations. - The offshore pipeline assets include: - The Typhoon gas pipeline, a 35-mile, 20-inch natural gas pipeline originating on the Chevron/BHP "Typhoon" platform in the Green Canyon area of the Gulf of Mexico extending to the ANR Patterson System in Eugene Island Block 371; and - The Typhoon oil pipeline, a 16-mile, 12-inch oil pipeline originating on the Chevron/BHP "Typhoon" platform and extending to a platform in Green Canyon Block 19 with onshore access through various oil pipelines. - The Texas NGL assets include: - a 163-mile, 4-inch to 6-inch propane pipeline extending from Corpus Christi to McAllen and the Hidalgo truck terminal facilities; - the Markham butane shuttle, a 144-mile, 8-inch pipeline with capacity of approximately 20 MBbls/d running between Corpus Christi and a leased storage facility at Markham with capacity of approximately 3.8 MMBbls; - a 76-mile, 6-inch pipeline with capacity of approximately 15 MBbls/d extending from Almeda to Texas City and the Texas City terminal; and - the Almeda fractionator, a 35 MBbls/d fractionator consisting of two trains, one of which is currently out of service, and related leased storage facilities of approximately 9.8 MMBbls; - a 265-mile, 8-inch pipeline with capacity of approximately 35 MBbls/d extending from Corpus Christi to Pasadena, which is currently out of service. The parties' obligations under the letter of intent are subject to the satisfaction of specified conditions, including negotiating and executing definitive agreements, obtaining third-party approvals and consents, obtaining satisfactory results from ongoing due diligence and obtaining acceptable financing satisfactory to us. We will be required to make approximately $46 million of capital expenditures to place the 8-inch pipeline back in service and make repairs and upgrades on the Markham butane shuttle and the Almeda fractionator. We expect to close this transaction in the fourth quarter of 2002. Ultimately, we expect to finance our acquisition of the San Juan assets through long-term debt and equity. Our current financing plan is outlined below (in millions):

Series C units.............................................. $350 Senior secured acquisition term loan........................ 282 Other debt.................................................. 150 ---- $782 ====

The equity component of the proposed acquisition contemplates us issuing to El Paso Corporation up to $350 million of our Series C units, a new class of our limited partner interests. The potential $350 million Series C issuance will be reduced by the proceeds from any common unit issuance we may consummate before the closing of the San Juan assets acquisition. The Series C units will be similar to our existing common units, except that the Series C units will be non-voting. After April 30, 2003, El Paso Corporation (or its subsidiaries, as applicable) will have the right to cause us to propose a vote of our common unitholders as to whether the Series C units should be converted into common units. If our common unitholders approve the conversion, then each Series C unit will convert into a common unit. If our common unitholders do not approve the conversion within 120 days after El Paso Corporation requests the vote, then the distribution rate for the Series C units will increase to 105 percent of the common unit distribution rate. Thereafter, the Series C unit distribution rate would increase on April 30, 38

2004 to 110 percent of the common unit distribution rate and on April 30, 2005 to 115 percent of the common unit distribution rate. The issue price for the Series C units will be the greater of $32 per unit or the average market price of a common unit for the five trading days ending on the business day immediately preceding the closing date. If the average market price is less than $27, the San Juan acquisition may be delayed, terminated or renegotiated. Assuming a price of $32 per unit, approximately 11 million units will be issued and El Paso Corporation would own approximately 41 percent, an increase from 26 percent of the limited partners interest. The remaining balance of the purchase price will be paid in cash. We expect to fund this portion of the purchase price with a $282 million senior secured acquisition term loan and other long-term debt of $150 million. In accordance with our procedures for evaluating and valuing material acquisitions with El Paso Corporation, our Special Conflicts Committee engaged an independent financial advisor and obtained two separate fairness opinions for the acquisition of the San Juan assets and the issuance of the Series C units. The opinions we received stated the transaction and the issuance were both fair to us and our unitholders. EPN Holding Assets In April 2002, EPN Holding acquired from El Paso Corporation midstream assets located in Texas and New Mexico, including one of the largest intrastate pipeline systems in Texas based on miles of pipe. The acquired assets include: - the EPGT Texas intrastate pipeline system; - the Waha natural gas gathering system and treating plant located in the Permian Basin region of Texas; - the Carlsbad natural gas gathering system located in the Permian Basin region of New Mexico; - an approximate 42.3 percent non-operating interest in the Indian Basin natural gas processing and treating facility located in southeastern New Mexico; - a 50 percent undivided interest in the Channel natural gas pipeline system located along the Gulf coast of Texas; - the TPC Offshore natural gas pipeline system located off the Gulf coast of Texas; and - a leased interest in the Wilson natural gas storage facility located in Wharton County, Texas. The $750 million sales price was adjusted for the assumption of $15 million of working capital related to natural gas imbalances. The net consideration of $735 million for the EPN Holding assets was comprised of the following: - $420 million of cash; - $119 million of assumed short-term indebtedness payable to El Paso Corporation, which has been repaid; - $6 million in common units; and - $190 million in assets, comprised of our Prince TLP and our nine percent Prince overriding royalty interest. To finance substantially all of the cash consideration related to this acquisition, EPN Holding entered into a $535 million limited recourse acquisition facility with a syndicate of commercial banks, of which $375 million has been repaid and the remaining amount was restructured in October 2002, as discussed in the Capital Resources section of this Item 2. 39

Hattiesburg Storage Facility In January 2002, we acquired a 3.3 million barrel propane storage business and leaching operation located in Hattiesburg, Mississippi from Suburban Propane Partners, L.P. for approximately $10 million. As part of the transaction, we entered into a long-term propane storage agreement with Suburban Propane Partners for a portion of the acquired propane storage capacity. Big Thicket In August 2002, we acquired the Big Thicket assets, which consist of the Silsbee compressor station and the Big Thicket gathering system, for approximately $11 million from BP America Production Company. The Silsbee compressor station acts as a booster station for a web of area gas gathering lines. The facility has four 1,200 horsepower gas compressors that boost low pressure field gas from 45 to 950 pounds of plant inlet pressure. The Big Thicket gathering system is comprised of approximately 150 miles of 4 to 10 inch diameter pipe with throughput of approximately 22 MMcf/d. PROJECTS Medusa Project We are constructing the $26 million, 37-mile Medusa natural gas pipeline extension of our Viosca Knoll gathering system with capacity to handle 160 MMcf/d of natural gas, which is expected to be in service in the first quarter of 2003, designed and located to gather production from Murphy Exploration and Production Company's Medusa development in the Gulf of Mexico. Murphy has dedicated 34,560 acres of property to this pipeline for the life of the reserves, which means that all natural gas produced from this acreage will flow through this pipeline. As of September 30, 2002, we have spent approximately $12.7 million related to this pipeline extension, which is currently under construction. We expect to fund the project through borrowings on our credit facility. Marco Polo Project In December 2001, we announced an agreement with Anadarko Petroleum Corporation under which we would construct, install and own the Marco Polo TLP with capacity to handle 100 MBbls/d of oil and 250 MMcf/d of natural gas. This TLP, which we expect to be in service in the fourth quarter of 2003, was designed and located to process oil and natural gas from Anadarko Petroleum Corporation's Marco Polo Field discovery in the Gulf of Mexico. Anadarko has dedicated 69,120 acres of property to this TLP, including the acreage underlying their Marco Polo Field discovery, for the life of the reserves. Anadarko will have firm capacity of 50 MBbls/d of oil and 150 MMcf/d of natural gas. The remainder of the platform capacity will be available to Anadarko for additional production and/or to third parties that have fields developed in the area. This TLP will be owned by our 50 percent owned Deepwater Gateway joint venture. We will operate the Deepwater Gateway joint venture, and the Marco Polo TLP will be operated by Anadarko. The total cost of the project is estimated to be $206 million, or approximately $103 million for our share. As of September 30, 2002, Deepwater Gateway has spent approximately $58.3 million on this TLP, which is currently under construction. In addition, we will construct and own a 36-mile, 14-inch oil pipeline and a 75-mile, 18-inch and 20-inch natural gas pipeline to support the Marco Polo TLP. The natural gas pipeline will gather natural gas from the Marco Polo platform in Green Canyon Block 608 and transport to the Typhoon natural gas pipeline in Green Canyon Block 237 with a maximum capacity of 400 MMcf/d. The oil pipeline will gather oil from the Marco Polo platform to our Allegheny pipeline in Green Canyon Block 164 with a maximum capacity of 100 MBbls/d. These pipelines are expected to be completed and placed in service in the first quarter of 2004, and are expected to cost $79 million to construct. As of September 30, 2002, we have spent approximately $1.3 million on these pipelines, which are in the development stage. In August 2002, Deepwater Gateway, our joint venture that owns the Marco Polo TLP, obtained a $155 million project loan at a variable interest rate from a group of commercial lenders to finance a substantial 40

portion of the cost to construct the Marco Polo TLP and related facilities. Upon completion of the construction, the project loan will convert into a term loan, subject to the terms of the loan agreement. The loan is collateralized by substantially all of Deepwater Gateway's assets. If Deepwater Gateway defaults on its payment obligations under the loan, we would be required to pay to the lenders all distributions we or any of our subsidiaries had received from Deepwater Gateway up to $22.5 million. As of September 30, 2002, Deepwater Gateway had no amounts outstanding under the project loan and had not paid us or any of our subsidiaries any distributions. Cameron Highway In February 2002, we announced that we will build and operate the $458 million, 390-mile Cameron Highway Oil Pipeline with capacity of 500 MBbls/d, which is expected to be in service by the third quarter of 2004, will provide producers with access to onshore delivery points in Texas and Louisiana. BP p.l.c., BHP Billiton and Unocal have dedicated 86,400 acres of property to this pipeline for the life of the reserves, including the acreage underlying their Holstein, Mad Dog and Atlantis developments in the deeper water regions of the Gulf of Mexico. In October 2002, we entered into a non-binding letter of intent with Valero Energy Corporation under which Valero would acquire a 50 percent interest in the entity we form to construct, install and own this pipeline, which we will operate. The formation of this joint venture is subject to specific conditions set forth in the letter of intent, including negotiating and executing definitive documentation and obtaining mutually acceptable financing. We are contractually committed to the Cameron Highway Project whether or not we obtain a partner. We expect that a majority of the costs of this project will be funded through project financing. It is estimated that the majority of the capital outlay for the project will occur in 2003 and 2004. As of September 30, 2002, we have spent approximately $3.1 million related to this pipeline, which is in the development stage. Falcon Nest In April 2002, we entered into an agreement to construct and own the $53 million Falcon Nest fixed-leg platform, together with related pipelines, with capacity to handle 300 MMcf/d of natural gas, which is expected to be in service during the first quarter of 2003, designed and located to process natural gas from Pioneer Natural Resources Company's and Mariner Energy, Inc.'s Falcon Field discovery in the Gulf of Mexico. Pioneer and Mariner have dedicated 69,120 acres of property, including acreage underlying their Falcon Field discovery, to this platform for the life of the reserves. As of September 30, 2002, we have spent approximately $18.2 million on this project, which is under construction. Petal Expansion In June 2002, we completed a $68 million, 8.9 Bcf (6.3 Bcf working capacity) expansion of our Petal natural gas storage facility, including a withdrawal facility and a 20,000 horsepower compression station, located near Hattiesburg, Mississippi. This brings the total working gas capacity of the Petal facility to 9.5 Bcf, of which 7 Bcf is dedicated to a subsidiary of The Southern Company, one of the largest producers of electricity in the United States, under a 20-year fixed-fee contract. In June 2002, we also completed a $100 million, 60-mile pipeline addition with capacity of 1.25 Bcf/d (currently FERC-certified to 700 MMcf/d) that interconnects with the storage facility and offers direct interconnects with the Southern Natural Gas, Transco and Destin pipeline systems. In June 2002, the interconnects with Southern Natural Gas and Destin were placed into service. In September 2002, the Transco interconnect was placed in service. Red Hawk In October 2002, we announced that we will build and operate a new $57 million, 16-inch pipeline to gather natural gas production from the Red Hawk Field located in the Garden Banks area of the Gulf of Mexico. We have entered into the related agreements with Kerr-McGee Oil and Gas Corporation, a wholly owned subsidiary of Kerr-McGee Corporation and Ocean Energy, Inc., which each hold a 50-percent working interest in the Red Hawk Field. The 86-mile pipeline, capable of transporting up to approximately 330 MMcf/d of natural gas, will originate in 5,300 feet of water at the Red Hawk Field and connect to the ANR 41

Pipeline system at Vermillion Block 397. We plan to place the new pipeline, which is in the development stage, in service during the second quarter of 2004. OTHER MATTERS As a result of current circumstances generally surrounding the energy sector, the creditworthiness of several industry participants has been called into question. As a result of these general circumstances, we have established an internal group to monitor our exposure to, and determine, as appropriate, whether we should request prepayments, letters of credit or other collateral from our counterparties. If these general conditions worsen and, as a result, several industry participants file for Chapter 11 bankruptcy protection, it could have a material adverse effect on our financial position, results of operations or cash flows. RELATED PARTY TRANSACTIONS For a discussion of our related party transactions, see Part I, Financial Information, Note 11. In our normal course of business we enter into transactions with various entities controlled directly or indirectly by El Paso Corporation, the parent of our general partner. In the third quarter of 2002, $25 million of our related party revenue came from El Paso Merchant Energy North America Company (Merchant Energy). Merchant Energy is a direct subsidiary of El Paso Corporation. Approximately $15 million of this revenue represents the proceeds received by us from selling to Merchant Energy hydrocarbons which we gain title to month to month under certain gathering and processing agreements with third party producers. These sales occur at market prices on an arms length basis, and we believe these sales can be replaced by similar arrangements with third parties at anytime should we so desire. The remaining $10 million of revenue is primarily related to transportation services provided to Merchant Energy by our pipelines, primarily the EPGT Texas intrastate pipeline system. Merchant Energy has contracted with us on both a firm and interruptible basis and currently utilizes its contracted capacity. In most cases these revenue streams are originated by third parties. Our largest related party revenue streams are generated by our three Texas fractionation facilities and our Chaco plant. In the case of our fractionation facilities, we are paid each month a fixed fee of $0.024 for each gallon of NGL that we fractionate into its component parts. El Paso Field Services (Field Services) an indirect subsidiary of El Paso Corporation, and a direct subsidiary of El Paso Tennessee Pipeline Co., pays us this fee. Field Services receives the NGL we fractionate at our facilities from producers in south Texas. The fractionated NGL is re-delivered to Field Services at the tailgate of the plants and then sold by Field Services to various petrochemical and refining customers located along the Texas gulf coast. In addition, Field Services has gathering and processing agreements with producers in the San Juan Basin. Field Services pays us a fee of $0.1344 per dekatherm of natural gas that we process at the Chaco plant. If we successfully close on our proposed acquisition of the San Juan assets, we will be purchasing, among other assets, the contracts Field Services has with the San Juan Basin producers and this related party revenue stream will end. SEGMENT RESULTS In light of our expectation of acquiring additional natural gas pipeline and processing assets, effective January 1, 2002, we revised and renamed our business segments to reflect the change in composition of our operations. In October 2001, we acquired the Chaco plant and reflected the operations of this asset in our Oil and NGL logistics segment. With the change in our segments, we moved the Chaco processing plant to our Natural gas pipelines and plants segment. As a result of our sale of the Prince TLP and our nine percent overriding interest in the Prince Field in April 2002, the results of operations from these assets are reflected as discontinued operations in our statements of income for all periods presented and are not reflected in our segment results below. Beginning in 2002, operations from our oil and natural gas production activities are reflected in Other. To the extent possible, results of operations have been reclassified to conform to the current business segment presentation, although these results may not be indicative of the results which would have been achieved had the revised business segment structure been in effect during those periods. Operating revenues and expenses by segment include intersegment revenues and expenses which are eliminated in consolidation. 42

The following table presents EBIT by segment and in total for each of the quarter and nine months ended September 30:

EBIT variances are discussed in the segment results below. NATURAL GAS PIPELINES AND PLANTS

In connection with our April 2002 EPN Holding asset acquisition, we added assets to this segment with contracts whereby we may purchase natural gas from producers at the wellhead for an index price less an amount that compensates us for gathering services. We then sell the natural gas into the open market at points on our system at the same index prices. Accordingly, our operating revenues and costs of natural gas are impacted by changes in energy commodity prices, while our margin is unaffected. For these reasons, we believe that gross margin (revenue less cost of natural gas) provides a more accurate and meaningful basis for analyzing operating results for the Natural gas pipelines and plants segment. Third Quarter 2002 Compared to Third Quarter 2001 Natural gas pipelines and plants margin for the quarter ended September 30, 2002, was $60.2 million higher than in the same period in 2001. Approximately $41.9 million of the increase was due to our April 2002 purchase of the EPN Holding assets from subsidiaries of El Paso Corporation and $8.0 million to our purchase of the Chaco plant in October 2001. Additionally, approximately $8.2 million of the increase was due to our consolidation of Deepwater Holdings in October 2001. Further contributing to the increase was $1.2 million relating to our purchase of the Big Thicket assets in August 2002 and $0.5 million relating to the operations of the Pelican Stabilizer, which was placed in service in March 2002. Excluding the contribution from these 43

newly acquired assets, margins increased by $1.4 million. Offsetting these increases was a $1 million mark-to-market non-cash loss associated with a derivative transaction we entered into during the quarter to economically hedge a portion of the 2003 price risk exposure for gathering services associated with our proposed San Juan acquisition. In addition, our third quarter 2002 margin decreased by $0.6 million as a result of Hurricane Isidore in September 2002. We expect our fourth quarter margins to be lower due to Hurricane Lili which occurred in October 2002. Offsetting this fourth quarter impact, will be additional volumes from the startup of production in the Camden Hills and Aconcagua Fields which will be delivered to our Viosca Knoll system. Operating expenses for the quarter ended September 30, 2002, were $33.9 million higher than the same period in 2001 primarily due to our April 2002 purchase of the EPN Holding assets, our purchase of the Chaco plant in October 2001, and our consolidation of Deepwater Holdings. Excluding the operating costs of the newly acquired assets, operating expenses increased by $1.3 million due to accelerated non-routine maintenance on our HIOS system, as well as a bad debt write-off. Other income (loss) for the quarter ended September 30, 2002, was $0.4 million lower than the same period in 2001 primarily due to purchase price adjustments related to Deepwater's sale of Stingray, UTOS and the West Cameron dehydration facility. After our acquisition of the remaining interest in Deepwater Holdings in October 2001, Deepwater Holdings became a consolidated subsidiary. Nine Months Ended 2002 Compared to Nine Months Ended 2001 Natural gas pipeline and plants margin for the nine months ended September 30, 2002, was $139.4 million higher than the same period in 2001. Approximately $83.3 million of the increase was due to our April 2002 purchase of the EPN Holding assets from subsidiaries of El Paso Corporation and $24.4 million to our purchase of the Chaco plant in October 2001. Additionally, approximately $27.4 million of the increase was due to our consolidation of Deepwater Holdings in October 2001. Further contributing to the increase was $1.2 million relating to our purchase of the Big Thicket assets in August 2002 and $0.6 million relating to the operations of the Pelican Stabilizer, which was placed in service in March 2002. Excluding the contribution from these newly acquired assets, margins increased by $3.5 million. Offsetting these increases was a $1 million mark-to-market non-cash loss associated with a derivative transaction we entered into during the third quarter to economically hedge a portion of the 2003 price risk exposure for gathering services associated with our proposed San Juan acquisition. In addition, our 2002 margin decreased by $0.6 million as a result of Hurricane Isidore in September 2002. We expect our fourth quarter margins to be lower due to Hurricane Lili which occurred in October 2002. Offsetting this fourth quarter impact, will be additional volumes from the startup of production in the Camden Hills and Aconcagua Fields which will be delivered to our Viosca Knoll system. Operating expenses for the nine months ended September 30, 2002 were $71.9 million higher than the same period in 2001 primarily due to our April 2002 purchase of the EPN Holding assets, our purchase of the Chaco plant in October 2001, and our consolidation of Deepwater Holdings. Excluding the operating costs of the newly acquired assets, operating expenses increased by $3.7 million. Other income for the nine months ended September 30, 2002, was $4.5 million lower than the same period in 2001 primarily due to our recognition in 2001 of $22.0 million in additional consideration from El Paso Corporation associated with the sale of our Gulf of Mexico pipeline assets in 2001, partially offset by net losses of $7.8 million due to the sale of our interests in the Tarpon and Green Canyon pipeline assets in January 2001. Also contributing to this offset were lower earnings from unconsolidated affiliates of $10.3 million, which primarily relates to Deepwater Holdings' sale of Stingray, UTOS and the West Cameron dehydration facility and the sale of our interest in Nautilus and Manta Ray Offshore in 2001. 44

OIL AND NGL LOGISTICS

- ---------- (1) Represents 100% of the volumes flowing through the pipeline. Third Quarter 2002 Compared to Third Quarter 2001 For the quarter ended September 30, 2002, revenues were $0.7 million lower than the same period in 2001 primarily due to lower volumes on EPN Texas. Offsetting this decrease was our acquisitions of the Hattiesburg propane storage facility in January 2002 and the Anse La Butte NGL storage facility in December 2001 and higher volumes on Allegheny. Operating expenses for the quarter ended September 30, 2002, were $0.2 million higher than the same period in 2001 primarily due to our acquisition of the Hattiesburg propane storage facility in January 2002 and the Anse La Butte NGL storage facility in December 2001 offset by the modification of the operating agreement in connection with the EPN Holding acquisition in April 2002 between EPN Texas and El Paso Field Services, which reduced the amount of monthly operating charges to us. Other income for the quarter ended September 30, 2002, was $0.3 million lower than the same period in 2001 primarily due to a decrease in earnings from unconsolidated affiliates due to lower volumes on Poseidon Oil Pipeline partially attributable to Hurricane Isidore in September 2002. We expect our fourth quarter earnings from unconsolidated affiliates to be lower due to Hurricane Lili which occurred in October 2002. Offsetting this fourth quarter impact, will be additional volumes related to new contracts that Poseidon Oil Pipeline has entered into. These contracts start in November 2002 and December 2002 and have a six month duration. We will realize our 36 percent share of the volume increase through earnings from unconsolidated affiliates over the next seven months. Nine Months Ended 2002 Compared to Nine Months Ended 2001 For the nine months ended September 30, 2002, revenues were $5.2 million higher than the same period in 2001 primarily due to our acquisitions of the EPN Texas transportation and fractionation assets in February 2001, the Hattiesburg propane storage facility in January 2002, and the Anse La Butte NGL storage facility in December 2001. Additionally, higher volumes on Allegheny also contributed to the increase in revenues. Operating expenses for the nine months ended September 30, 2002, were $3.2 million higher than the same period in 2001 primarily due to our acquisitions of the EPN Texas transportation and fractionation assets in February 2001, the Hattiesburg propane storage facility in January 2002, and the Anse La Butte NGL storage facility in December 2001. Other income for the nine months ended September 30, 2002, was $2.4 million lower than the same period in 2001 primarily due to a decrease in earnings from unconsolidated affiliates due to lower volumes on Poseidon Oil Pipeline partially attributable to Hurricane Isidore in September 2002. We expect our fourth 45

quarter earnings from unconsolidated affiliates to be lower due to Hurricane Lili which occurred in October 2002. Offsetting this fourth quarter impact, will be additional volumes related to new contracts that Poseidon Oil Pipeline has entered into. These contracts start in November 2002 and December 2002 and have a six month duration. We will realize our 36 percent share of the volume increase through earnings from unconsolidated affiliates over the next seven months. NATURAL GAS STORAGE

Third Quarter 2002 Compared to Third Quarter 2001 For the quarter ended September 30, 2002, revenues were $4.0 million higher than the same period in 2001 primarily due to the expansion of the Petal storage facility and our acquisition of the Wilson storage facility lease in April 2002. Storage capacity for the Petal facility has been subscribed to a subsidiary of the Southern Company for 7.0 Bcf and to BP for 1.65 Bcf. Expansion of the Petal storage facility was completed during the second quarter, and we commenced services to a subsidiary of the Southern Company in the third quarter of 2002. Petal's services under this contract will add $4.0 million of revenues during the fourth quarter of 2002. Operating expenses for the quarter were $3.0 million higher than the same period in 2001 primarily due to the expansion of our Petal storage facility in the second quarter of 2002 and the acquisition of the Wilson storage facility lease in April 2002. Nine Months Ended 2002 Compared to Nine Months Ended 2001 For the nine months ended September 30, 2002, revenues were $3.4 million higher than the same period in 2001 primarily due to the expansion of the Petal storage facility and our acquisition of the Wilson storage facility lease in April 2002. This increase was partially offset by a decrease in revenues attributable to lower commodity revenues and interruptible storage services at our Hattiesburg facility during 2002. Operating expenses for the nine months ended September 30, 2002, were $5.3 million higher than the same period in 2001 primarily due to the expansion of our Petal storage facility in the second quarter of 2002, the acquisition of the Wilson storage facility lease in April 2002 and a favorable resolution of an imbalance settlement in 2001. 46

PLATFORM SERVICES

Third Quarter 2002 Compared to Third Quarter 2001 For the quarter ended September 30, 2002, revenues were $1.8 million lower than in the same period in 2001 primarily due to the expiration in June 2002, in accordance with the original contract terms, of the fixed fee portion of the Viosca Knoll 817 platform access fee contract with Flextrend Development Company, our wholly owned subsidiary. Operating expenses for the same periods were $0.2 million higher due to higher direct costs. Other income for the quarter ended September 30, 2002 reflects income from an intersegment investment that is eliminated in our Other segment in consolidation. Nine Months Ended 2002 Compared to Nine Months Ended 2001 For the nine months ended September 30, 2002, revenues were $0.2 million lower than the same period in 2001 primarily due to the expiration in June 2002, in accordance with the original contract terms, of the fixed fee portion of the Viosca Knoll 817 platform access fee contract with Flextrend Development Company, our wholly owned subsidiary, partially offset by retroactive billings for fixed monthly platform access fees and a retroactive gas dehydration fee on the East Cameron 373 platform. Operating expenses for the same periods were $0.9 million lower due to lower direct costs. Other income for the nine months ended September 30, 2002 reflects income from an intersegment investment that is eliminated in our Other segment in consolidation. Other loss for the nine months ended September 30, 2001 reflects approximately $3.0 million of losses recognized on the sales of our Gulf of Mexico platform assets in January 2001, offset by the additional consideration from El Paso Corporation related to the sale of these assets. OTHER, NET Third Quarter 2002 Compared to Third Quarter 2001 Earnings before interest expense and taxes related to non-segment activity for the quarter ended September 30, 2002, were $0.2 million higher than the same period in 2001. The increase was primarily due to higher natural gas and oil prices offset by lower volumes attributable to a decrease in natural gas production as a result of normal decline of existing reserves. Third quarter 2002 EBIT also decreased by $0.2 million as a 47

result of Hurricane Isidore in September 2002. We expect our fourth quarter 2002 EBIT to be lower due to Hurricane Lili which occurred in October 2002. Nine Months Ended 2002 Compared to Nine Months Ended 2001 Earnings before interest expense and taxes related to non-segment activity for the nine months ended September 30, 2002, were $6.0 million lower than the same period in 2001. The decrease was primarily due to lower natural gas and oil prices, as well as lower volumes attributable to a decrease in natural gas production as a result of normal decline of existing reserves, partially offset by lower operating expenses and depletion. Additionally, EBIT decreased by $0.2 million as a result of Hurricane Isidore in September 2002. We expect our fourth quarter 2002 EBIT to be lower due to Hurricane Lili which occurred in October 2002. INTEREST AND DEBT EXPENSE Interest and debt expense, net of capitalized interest, for the quarter and nine month periods ended September 30, 2002, was approximately $12.2 million and $25.9 million higher than the same periods in 2001. This increase is primarily due to an increase in the average outstanding balance of our revolving credit facility, the amounts outstanding under the EPN Holding acquisition facility which we entered to purchase the EPN Holding assets in April 2002, and the $230 million of 8.5% senior subordinated notes issued in May 2002. Capitalized interest for the quarter and nine months ended September 30, 2002 was $0.7 million and $4.3 million compared to $3.4 million and $9.7 million for the same periods in 2001.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS We have made statements in this document that constitute forward-looking statements. These statements are subject to risks and uncertainties. Forward-looking statements include information concerning possible or assumed future results of operations. These statements may relate to information or assumptions about: - earnings per unit; - capital and other expenditures; - cash distributions; - financing plans; - capital structure; - liquidity and cash flow; - pending legal proceedings and claims, including environmental matters; - future economic performance; - operating income; - cost savings; - management's plans; and - goals and objectives for future operations. Important factors that could cause actual results to differ materially from estimates or projections contained in forward-looking statements are described in our Annual Report on Form 10-K for the year ended December 31, 2001, and our other filings with the Securities and Exchange Commission. Where any forward-looking statement includes a statement of the assumptions or bases underlying the forward-looking statement, we caution that, while we believe these assumptions or bases to be reasonable and made in good faith, assumed facts or bases almost always vary from the actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, we express an expectation or belief as to future results, such expectation or belief is expressed in good faith and is believed to have a reasonable basis. We cannot assure you, however, that the statement of expectation or belief will result or be achieved or accomplished. These statements relate to analyses and other information which are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. These forward-looking statements are identified by their use of terms and phrases such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "predict," "project," "will," and similar terms and phrases, including references to assumptions. These forward-looking statements involve risks and uncertainties that may cause our actual future activities and results of operations to be materially different from those suggested or described. These risks may also be specifically described in our Current Reports on Form 8-K and other documents filed with the Securities and Exchange Commission. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information or otherwise. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those expected, estimated or projected. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK This information updates, and you should read it in conjunction with, our quantitative and qualitative disclosures about market risks reported in our Annual Report on Form 10-K for the year ended December 31, 49

2001, in addition to information presented in Items 1 and 2 of this Quarterly Report on Form 10-Q and our Current Reports on Form 8-K and 8-K/A. In August 2002, we entered into a derivative financial instrument to hedge our exposure during 2003 relating to gathering activities for changes in natural gas prices in the San Juan Basin in anticipation of our proposed acquisition of the San Juan assets. The derivative is a financial swap on 30,000 MMBtu per day whereby we receive a fixed price of $3.525 per MMBtu and pay a floating price based upon the San Juan index. We are accounting for this derivative under mark-to-market accounting since it does not qualify for hedge accounting under SFAS 133. As of September 30, 2002, the fair value of this derivative was a $1.0 million liability and we recognized this $1.0 million loss in the margin of our Natural gas pipelines and plants segment. Once the proposed acquisition of the San Juan assets is completed, we expect to designate this derivative as a cash flow hedge under SFAS 133. During 2001 and 2002, we entered into cash flow hedges in connection with our EPIA operations. As of September 30, 2002, the fair value of these cash flow hedges was an asset of approximately $49 thousand. During the nine months ended September 30, 2002, the majority of our cash flow hedges expired and we reclassified $1.4 million from accumulated other comprehensive income to earnings. Starting in April 2002, in connection with our EPN Holdings acquisition, we have swaps in place for our interest in the Indian Basin processing plant. As of September 30, 2002, the fair value of these cash flow hedges was a $126 thousand liability resulting in an unrealized loss of $126 thousand. During 2002, Poseidon entered into a two-year interest rate swap agreement. As of September 30, 2002, the fair value of its interest rate swap was a liability of $1.6 million resulting in an unrealized loss of $1.6 million. We include our 36 percent share of this liability of $0.6 million as a reduction of our investment in Poseidon and as an unrealized loss in other comprehensive income. Additionally, we have recognized in income our 36 percent share of Poseidon's realized loss of $0.9 million for the nine months ended September 30, 2002, or $0.3 million, through our earnings from unconsolidated affiliates. ITEM 4. CONTROLS AND PROCEDURES Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures within 90 days of the filing date of this quarterly report pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934 (the "Exchange Act"). Based on that evaluation, our principal executive officer and principal financial officer have concluded that these controls and procedures are effective. There were no significant changes in our internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation. Disclosure controls and procedures are our controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified under the Exchange Act. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

The Indenture, as supplemented by this Supplemental Indenture, remains in full force and effect and is hereby ratified and confirmed as the valid and binding obligation of the parties hereto. 3.7 TRUSTEE. The Trustee accepts the modifications of trusts referenced in the Indenture and effected by this Supplemental Indenture.

If for any reason the Administrative Agent shall have determined (which determination shall be conclusive absent manifest error) that it is unable to ascertain the Federal Funds Effective Rate, for any reason, including the inability or failure of the Administrative Agent to obtain sufficient quotations in accordance with the terms thereof, the Alternate Base Rate shall be determined without regard to clause (b) of the first sentence of this definition, until the circumstances giving rise to such inability no longer exist.

(a) Subject to the terms and conditions hereof, the Issuing Bank, in reliance on the agreements of the other Revolving Credit Lenders set forth in subsection 3.3(a), agrees to issue letters of credit (the "Letters of Credit") for the account of the Borrower on any Business Day during the Revolving Credit Commitment Period in such form as may be approved from time to time by the Issuing Bank; provided that the Issuing Bank shall have no obligation to issue any Letter of Credit if, after giving effect to such issuance, (1) the L/C Obligations would exceed the L/C Commitment or (2) the Available Revolving Credit Commitment would be less than zero or (3) the Aggregate Outstanding Revolving Credit Extensions of Credit would exceed the then aggregate Revolving Credit Commitments. (b) Each Letter of Credit shall: (i) be denominated in Dollars and shall be either (A) a standby letter of credit issued to support obligations of the Borrower or any Restricted Subsidiary, contingent or otherwise, in connection with the working capital and business needs of the Borrower or such Restricted Subsidiary, as the case may be, in the ordinary course of business, or (B) a commercial letter of credit issued in respect of the purchase of goods or services by the Borrower or any Restricted Subsidiary in the ordinary course of business; and 31

(ii) expire no later than the earlier of (A) one year after the date of issuance or renewal thereof in accordance with the term of such Letter of Credit; provided that any Letter of Credit with an expiry date occurring one year after its issuance may be renewed for additional one-year periods and (B) five Business Days prior to the Revolving Credit Termination Date. (c) Each Letter of Credit shall be subject to the Uniform Customs and, to the extent not inconsistent therewith, the laws of the State of New York. (d) The Issuing Bank shall not at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause the Issuing Bank or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law. (e) Letters of Credit issued under the Existing Credit Agreement which are outstanding on the Restatement Closing Date shall be deemed to be Letters of Credit issued under this Agreement on the Restatement Closing Date. Section 3.2 Procedure for Issuance of Letters of Credit. The Borrower may from time to time request that the Issuing Bank issue a Letter of Credit by delivering to the Issuing Bank at its address for notices specified herein an Application therefor, completed to the satisfaction of the Issuing Bank, and such other certificates, documents and other papers and information as the Issuing Bank may reasonably request. Upon receipt of any Application, the Issuing Bank will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Bank be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Bank and the Borrower. The Issuing Bank shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. Section 3.3 Participations and Payments in Respect of the Letters of Credit. (a) The Issuing Bank irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce the Issuing Bank to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Bank, on the terms and conditions hereinafter stated, for such L/C Participant's own account and risk an undivided interest equal to such L/C Participant's L/C Commitment Percentage in the Issuing Bank's obligations and rights under each Letter of Credit issued hereunder and the amount of each draft paid by the Issuing Bank thereunder. (b) Each L/C Participant unconditionally and irrevocably agrees with the Issuing Bank that, if a draft is paid under any Letter of Credit for which the Issuing Bank is not reimbursed on the day of such payment in full by the Borrower in immediately available funds, such Revolving Credit Lender shall pay to the Issuing Bank upon demand at the Issuing Bank's address for notices specified herein an amount equal to such L/C Participant's L/C Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed. Each 32

L/C Participant's obligation to make each such payment to the Issuing Bank, and the Issuing Bank's right to receive the same, are absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limiting the effect of the foregoing, the occurrence or continuance of a Default or Event of Default or the failure of any other L/C Participant to make any payment under this Section 3.3, and each L/C Participant further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each L/C Participant shall indemnify and hold harmless the Issuing Bank from and against any and all losses, liabilities (including, without limitation, liabilities for penalties), actions, suits, judgments, demands, costs and expenses (including reasonable attorneys' fees) resulting from any failure of such L/C Participant to provide, or from any delay in providing, the Issuing Bank with such L/C Participant's L/C Commitment Percentage of such payment in accordance with the provisions of this Section 3.3, but no L/C Participant shall be so liable for any such failure on the part of any other L/C Participant. (c) If any amount required to be paid by any L/C Participant to the Issuing Bank pursuant to subsection 3.3(a) in respect of any unreimbursed portion of any payment made by the Issuing Bank under any Letter of Credit is paid to the Issuing Bank within two Business Days after the date such payment is due, such L/C Participant shall pay to the Issuing Bank on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal funds rate, as quoted by the Issuing Bank, during the period from and including the date such payment is required to the date on which such payment is immediately available to the Issuing Bank, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any such amount required to be paid by any L/C Participant pursuant to subsection 3.3(a) is not in fact made available to the Issuing Bank by such L/C Participant within two Business Days after the date such payment is due, the Issuing Bank shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Alternate Base Rate Loans hereunder. A certificate of the Issuing Bank submitted to any L/C Participant with respect to any amounts owing under this Section 3.3 shall be conclusive in the absence of manifest error. (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 1/8 of 1% 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 33

date of issuance of each Letter of Credit and on the last day of each March, June, September and December thereafter, commencing June 30, 2001. 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 June 30, 2001. 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. (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 34

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 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. 35

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 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 Restatement Closing 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 36

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 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. 37

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). (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. 38

(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 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 Initial Term Loans or Additional Term Loans of any series shall be made pro rata according to the respective Term Loan Commitment Percentages applicable to such Initial Term Loans or 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 39

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 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. 40

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: (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. 41

Section 4.10 Taxes. (a) All payments made by the Borrower under this Agreement and the Notes shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding, in the case of the Administrative Agent, the Collateral Agent and each Lender, net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent, the Collateral Agent or such Lender, as the case may be, as a result of a present or former connection between the jurisdiction of the government or taxing authority imposing such tax and the Administrative Agent, the Collateral Agent or such Lender (excluding a connection arising solely from the Administrative Agent, the Collateral Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or the Notes) or any political subdivision or taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, duties, charges, fees, deductions and withholdings being hereinafter called "Taxes"). If any Taxes are required to be withheld from any amounts payable to the Administrative Agent, the Collateral Agent or any Lender hereunder or under the Notes, the amounts so payable to the Administrative Agent, the Collateral Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent, the Collateral Agent or such Lender (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and the Notes. Whenever any Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account, for the account of the Collateral Agent or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent, the Collateral Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent, the Collateral Agent or any Lender as a result of any such failure. 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. (b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall: (i) deliver to the Borrower and the Administrative Agent (A) two duly completed copies of United States Internal Revenue Service Form W8-ECI or W8-BEN, or successor applicable form, as the case may be, and (B) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be; (ii) deliver to the Borrower and the Administrative Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (iii) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Administrative Agent; 42

unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Administrative Agent. Such Lender shall certify (i) in the case of a Form W8-ECI or W8-BEN, that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an exemption from United States backup withholding tax. 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. 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 pursuant to subsection 8.6(b) or 8.6(e) 43

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(d), 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. The Borrower and the Co-Borrower hereby designate all Obligations of the Borrower and its Subsidiaries (including the Co-Borrower) under this Agreement and the other Loan Documents as Designated Senior Debt, as such term is defined in the Senior Subordinated Note Indentures.

No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or the Notes or the Applications. This Agreement has been, and each Note and the Applications will be, duly executed and delivered on behalf of the Borrower. This Agreement constitutes, and each Note and each other Loan Document to which the Borrower is a party when executed and delivered will constitute, a legal, valid and binding obligation of the Borrower enforceable against the Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 45

(b) Each of the Subsidiary Guarantors has the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and has taken all necessary action to authorize the execution, delivery and performance of the Loan Documents to which it is a party.

Each of the Loan Documents to which such Subsidiary Guarantor is a party will be duly executed and delivered on behalf of such Subsidiary Guarantor. Each Loan Document to which such Subsidiary Guarantor is a party will, when executed and delivered, constitute a legal, valid and binding obligation of such Subsidiary Guarantor enforceable against such Subsidiary Guarantor in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). Section 5.5 No Legal Bar. The execution, delivery and performance of this Agreement, the Notes and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or Contractual Obligation of any Loan Party, or, to the best knowledge of the Borrower, any Joint Venture any of the interests in which is owned by a Restricted Subsidiary, and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any such Requirement of Law or Contractual Obligation. Section 5.6 No Material Litigation. Except as set forth on Schedule 5.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any of its Subsidiaries, or, to the best knowledge of the Borrower, any Joint Venture any of the interests in which is owned by a Restricted Subsidiary, or against any of its or their respective properties or revenues (a) with respect to this Agreement, the Notes or any of the other Loan Documents or any of the transactions contemplated hereby or thereby, or (b) which could reasonably be expected to have a Material Adverse Effect. Section 5.7 No Default. No Loan Party, and, to the best knowledge of the Borrower, no Joint Venture any of the interests in which is owned by a Restricted Subsidiary, is in default under or with respect to any of its Contractual Obligations in any respect which could reasonably be expected to have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing. Section 5.8 Ownership of Property; Liens.

No claim has been asserted and is pending by any Person challenging or questioning the use of any such Intellectual Property or the validity or effectiveness of any such Intellectual Property, nor does the Borrower know of any valid basis for any such claim. The use of such Intellectual Property by the Borrower and its Restricted Subsidiaries does not infringe on the rights of any Person, except for such claims and infringements that, in the aggregate, do not have a Material Adverse Effect.

Section 10.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower which may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent's gross negligence or willful misconduct. The agreements in this Section 10.7 shall survive the payment of the Notes and all other amounts payable hereunder. Section 10.8 Administrative Agent in Its Individual Capacity. The Administrative Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Administrative Agent were not the Administrative Agent hereunder and under the other Loan Documents. With respect to its Loans made or renewed by it and any Note issued to it and with respect to the Letters of Credit, the Administrative Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not the Administrative Agent.

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. Without limiting the foregoing, none of the Lenders so identified as a "co-syndication agent" or a "co-documentation agent" shall have or be deemed to have any fiduciary relationship with any Lender.

The Borrower agrees (a) to pay or reimburse the Administrative Agent and the Collateral Agent for all their respective reasonable out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement, the Notes and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the fees and disbursements of counsel to the Administrative Agent and the Collateral Agent, (b) to pay or reimburse each Lender, the Administrative Agent and the Collateral Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the Notes, the other Loan Documents and any such other documents, including, without limitation, the fees and disbursements of counsel to the Administrative Agent, to the Collateral Agent and to the several Lenders, (c) to pay, indemnify, and hold each Lender, the Administrative Agent and the Collateral Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, 88

which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the Notes, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Lender, the Administrative Agent, the Collateral Agent, the Co-Syndication Agents, the Co-Documentation Agents, and their Affiliates, and their respective directors, officers, employees, agents and advisors (each such person being called an "Indemnified Party") harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments and suits, and reasonable costs, expenses or disbursements, of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the Notes and the other Loan Documents, the use of the proceeds of the Loans, including the use and reliance on electronic, telecommunications or other information or transmission systems in connection with the Loan Documents (all the foregoing in this clause (d), collectively, the "indemnified liabilities"), REGARDLESS OF WHETHER OR NOT SUCH INDEMNIFIED LIABILITIES ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AN INDEMNIFIED PARTY, provided, that the Borrower shall have no obligation hereunder to an Indemnified Party with respect to indemnified liabilities arising from (i) the gross negligence or willful misconduct of such Indemnified Party or (ii) legal proceedings commenced against an Indemnified Party by any security holder or creditor thereof arising out of and based upon rights afforded any such security holder or creditor solely in its capacity as such. The agreements in this Section shall survive repayment of the Notes and all other amounts payable hereunder. Section 11.6 Successors and Assigns; Participations; Purchasing Lenders. (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent, the Collateral Agent, all future holders of the Notes and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender. (b) Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, and after notice to the Borrower, at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan owing to such Lender, any Note held by such Lender, any Revolving Credit Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the other Loan Documents, and the Borrower, the Administrative Agent 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. The Borrower agrees that if amounts outstanding under this Agreement and the Notes are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in 89

amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in subsection 11.7(a) as fully as if it were a Lender hereunder. 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 amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. No Lender shall be entitled to create in favor of any Participant, in the participation agreement pursuant to which such Participant's participating interest shall be created or otherwise, any right to vote on, consent to or approve any matter relating to this Agreement or any other Loan Document except for those specified 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 or any successor or Affiliate thereof and with respect to any Term Loan Lender, such Term Loan Lender may sell to any Lender, an Approved Fund or any successor or Affiliate thereof 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 M, 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 thereof, 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 $10,000,000, 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 $10,000,000 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. For purposes of the proviso contained in the preceding sentence, the amount described therein shall be aggregated in respect to each Lender and its related Affiliates, if any. 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 90

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, Total EPN Group Lender Credit Percentages or Revolving Credit Commitment 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 Original Closing Date or the Restatement Closing Date, 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 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. 91

(f) The Borrower authorizes each Lender to disclose to any Participant or Purchasing Lender (each, a "Transferee") and any prospective Transferee any and all financial 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, 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 92

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 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 Article 5069-1D.001 et seq., as amended, of the Texas Revised Civil Statutes 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 93

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 11.13 Submission To Jurisdiction; Waivers.

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; 94

(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 employee, officer, director, accountant, attorney or consultant of such Person, or any examiner or other Governmental Authority, (b) that has been or is made public by EPEPC, 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, (c) that is or becomes available to any such Person from a third party on a non-confidential basis, (d) that is required to be disclosed by any Requirement of Law, including to any bank examiners or regulatory authorities, (e) that is required to be disclosed by any court, agency, arbitrator or legislative body, or (f) to any Transferee or proposed Transferee. 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. Section 11.17 ACKNOWLEDGEMENT OF NO CLAIMS, OFFSETS OR DEFENSES; RELEASE BY THE LOAN PARTIES. BORROWER, ON BEHALF OF ITSELF AND EACH OF THE OTHER LOAN PARTIES, ACKNOWLEDGES THAT NO LOAN PARTY NOR ANY OF THEIR RESPECTIVE OWNERS, DIRECTORS, SUCCESSORS, ASSIGNS, AGENTS, OFFICERS, EMPLOYEES, AND REPRESENTATIVES (COLLECTIVELY, THE "BORROWER AFFILIATES PARTIES") HAS ANY CLAIM, DEMAND, RIGHT OF OFFSET, CAUSE OF ACTION IN LAW OR IN EQUITY, LIABILITY OR DAMAGES OF ANY NATURE WHATSOEVER, WHETHER FIXED OR CONTINGENT (HEREINAFTER COLLECTIVE CALLED "CLAIMS") THAT COULD BE ASSERTED IN CONNECTION WITH, OR WHICH WOULD IN ANY OTHER MANNER BE RELATED TO, THE EXISTING CREDIT AGREEMENT OR ANY PROMISSORY NOTES OR OTHER AGREEMENTS, TRANSACTIONS OR OTHER ACTIONS PRIOR TO THE DATE HEREOF INVOLVING ANY OF THE BORROWER AFFILIATED PARTIES AND LENDERS ("THE PRIOR AGREEMENTS AND ACTIVITIES").

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 CORPORATIONS 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 performance of any act by any party, and all rights to the Collateral shall revert to the respective Loan Parties. At the request and expense of any Loan Party following any such termination, the Collateral Agent shall deliver to such Loan Party any Collateral held by the Collateral Agent under the Security Documents, and execute and deliver to such Loan Party such documents as such Loan Party shall reasonably request to evidence such termination. (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 Security Document 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 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 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 11.19 Co-Borrower's Obligations. The Co-Borrower is a party hereto for purposes of providing co-extensive obligors (on a joint and several basis) for the Obligations, although the parties acknowledge that the Co-Borrower shall not have any substantial assets or 96

other property. All references in this Agreement and the other Loan Documents to the "Borrower" shall be deemed to include a reference to the Co-Borrower, mutatis mutandis, whether or not actual reference is made thereto; provided, that, without limiting the generality of the foregoing, any obligations by any of the parties hereto to the Borrower shall be deemed fulfilled with respect to the Co-Borrower when fulfilled with respect to the Borrower.

The Collateral Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the EPN Group Administrative Agents acting jointly or the Required EPN Group 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 EPN Group 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 EPN Group 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 EPN Group Lenders shall appoint from among the EPN Group Lenders a successor agent for the EPN Group 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 99

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. After any retiring Collateral Agent's resignation as Collateral 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 Collateral Agent under this Agreement and the other Loan Documents. Section 12.8 Amendment. None of the terms or provisions of this Article XII may be amended, modified or waived without the written consent of the then Collateral Agent.

Annex I to Schedule I (Page 1)

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 under the terms of the Deepwater Gateway, L.L.C. Credit Agreement, as amended, restated or otherwise modified through the date of this Agreement. The Borrower's obligations under such agreement are capped at $30.0 million. The Borrower is party to a sponsor agreement under the Poseidon Oil Pipeline Company, L.L.C. Credit Agreement, as amended, restated or otherwise modified through the date of this Agreement pursuant to which the Borrower guarantees the performance of Poseidon Pipeline Company L.L.C.'s obligations under the limited liability company agreement of Poseidon Oil Pipeline Company, L.L.C. 2. Dispositions or Acquisitions of Business Properties since June 30, 2002: None Schedule 5.1 (Page 2)

SCHEDULE 5.6 MATERIAL LITIGATION In 1997, the Borrower, along with several subsidiaries of El Paso Corporation, 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 under report 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. 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. 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. 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 Quinque complaint was transferred to the same court handling the Grynberg complaint and has now been sent back to Kansas State Court for further proceedings. A motion to dismiss this case is pending. Under the terms of the Borrower's agreement to acquire the EPNHC assets, subsidiaries of El Paso Corporation have agreed to indemnify the Borrower against all obligations related to existing legal matters at the acquisition date, including the legal matters involving Leapartners, L.P., City of Edinburg (the "City") and Houston Pipe Line Company LP discussed below. During 2000, Leapartners, L.P. filed a suit against an affiliate of El Paso Corporation and others in the District Court of Loving County, Texas, alleging a breach of contract to gather and process gas in areas of western Texas related to an asset now owned by EPNHC. In May 2001, the court ruled in favor of Leapartners, L.P. and entered a judgment against El Paso Field Services, L.P. of approximately $10 million. El Paso Field Services, L.P. has filed an appeal with the Eighth Court of Appeals in El Paso, Texas. Also, EPGT Texas Pipeline, now owned by EPNHC, is involved in litigation with the City concerning the City's claim that EPGT Texas Pipeline was required to pay pipeline franchise fees under a contract the City had with Rio Grande Valley Gas Company, which was previously owned by EPGT Texas Pipeline and is now owned by Southern Union Gas Company ("Southern Union"). An adverse judgment against Southern Union and EPGT Texas Pipeline was rendered in December 1998 and upheld for breach of contract, holding both EPGT Texas Pipeline 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 EPGT Texas Pipeline and Southern Union's entities that were not parties to the contract with the City. EPGT Texas Pipeline has appealed this case to the Texas Supreme Court seeking reversal of the judgment rendered against EPGT Texas Pipeline. The City seeks a remand to the trial court of its claim of tortious interference against EPGT Texas Pipeline. The briefing before the Texas Supreme Court is complete. Schedule 5.6 (Page 1)

In December 2000, a 30-inch natural gas pipeline jointly owned now by EPNHC and Houston Pipe Line Company LP ruptured in Mont Belvieu, Texas, near Baytown, resulting in substantial property damage and minor physical injury. EPNHC is the operator of the pipeline. Lawsuits have been filed in state district court in Chambers County, Texas. An additional landowner has intervened in the Chambers County suits, as well as the homeowners' insurers. The suits seek recovery for physical pain and suffering, mental anguish, physical impairment, medical expenses, and property damage. Houston Pipe Line Company LP has been added as an additional defendant. In accordance with the terms of the operating agreement, EPNHC has agreed to assume the defense of and to indemnify Houston Pipe Line Company LP in the litigated cases. Discovery is proceeding and trial is set for November 2002. As discussed above, any obligation to Houston Pipe Line Company LP incurred by EPNHC is indemnified by subsidiaries of El Paso Corporation.

EXHIBIT A-1 FORM OF REVOLVING CREDIT NOTE $_________ New York, New York October 10, 2002 FOR VALUE RECEIVED, the undersigned, EL PASO ENERGY PARTNERS, L.P., a Delaware limited partnership (the "Borrower") and EL PASO ENERGY PARTNERS FINANCE CORPORATION, a Delaware corporation (the "Co-Borrower"), hereby jointly and severally, unconditionally promise to pay to the order of _____ (the "Lender") at the office of JPMorgan Chase Bank located at 270 Park Avenue, New York, New York 10017, in lawful money of the United States of America and in immediately available funds, the principal amount of the lesser of (a) _________ ($_______), and (b) the aggregate unpaid principal amount of all Revolving Credit Loans made by the Lender to the undersigned pursuant to Section 2.1 of the Credit Agreement hereinafter referred to, on the Revolving Credit Termination Date (as defined in the Credit Agreement) such principal to be paid on the date and in the amounts set forth in Section 2.2 of the Credit Agreement and on such other dates and in such other amounts set forth in the Credit Agreement. Each of the undersigned further agrees to pay interest in like money at such office on the unpaid principal amount hereof from time to time from the date hereof at the applicable rate per annum set forth in Section 4.4 of the Credit Agreement until any such amount shall become due and payable (whether at the stated maturity, by acceleration or otherwise), and thereafter on such overdue amount at the rate per annum set forth in subsection 4.4(c) of said Credit Agreement until paid in full (both before and after judgment). Interest shall be payable in arrears on each Interest Payment Date commencing on the first such date to occur after the date hereof, provided that interest accruing pursuant to subsection 4.4(c) of the Credit Agreement shall be payable on demand. In no event shall the interest payable hereon, whether before or after maturity, exceed the maximum interest which, under applicable law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how interest accrues hereon. The holder of this Note is authorized to record the date, type and amount of each Revolving Credit Loan made by the Lender pursuant to Section 2.1 of said Credit Agreement, each continuation thereof, each conversion of all or a portion thereof to another type, the date and amount of each payment or prepayment of principal with respect thereto, and, in the case of Eurodollar Loans, the length of each Interest Period with respect thereto, on the schedules annexed hereto and made a part hereof, or on a continuation thereof which shall be attached hereto and made a part hereof, which recordation shall constitute prima facie evidence of the accuracy of the information recorded in the absence of manifest error; provided that failure by the Lender to make any such recordation on this Note shall not affect the obligations of the Borrower under this Note or said Credit Agreement. Exhibit A-1 (Page 1)

This Note is one of the Revolving Credit Notes referred to in the Sixth Amended and Restated Credit Agreement, dated as of March 23, 1995, as amended (the "Existing Credit Agreement"), as amended and restated through October 10, 2002 (as further amended, supplemented or otherwise modified from time to time, the "Credit Agreement"), among the Borrower, the Co-Borrower, the Lender, the other financial institutions parties thereto and JPMorgan Chase Bank, as Administrative Agent, is entitled to the benefits thereof, is secured as provided therein and is subject to optional and mandatory prepayment in whole or in part as provided therein. Terms used herein which are defined in the Credit Agreement shall have such defined meanings unless otherwise defined herein or unless the context otherwise requires. Upon the occurrence of any one or more of the Events of Default specified in said Credit Agreement, all amounts then remaining unpaid on this Note shall become, or may be declared to be, immediately due and payable all as provided therein. This Note and the other Revolving Credit Notes are given in replacement and substitution for, but not payment or satisfaction of, certain revolving credit notes previously issued under the Credit Agreement. The indebtedness evidenced by such other revolving credit notes is continued in full force and effect hereunder. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. This Note evidences existing indebtedness under the Existing Credit Agreement (and its predecessors) and does not constitute payment of such indebtedness, and such indebtedness continues in full force and effect, as amended and restated in the Credit Agreement.

EXHIBIT O Description of Chaco Transactions I. The Chaco Plant The Chaco Plant, the third largest natural gas processing plant in the United States measured by liquids produced, is located in the San Juan Basin in New Mexico. It is capable of processing up to 600 Mmcf/d of natural gas and handling up to 50,000 bbls/d of NGLs. The Chaco Plant is a state of the art cryogenic plant that uses high pressures and extremely low temperatures to remove water, impurities and excess hydrocarbon liquids from the raw natural gas stream and recover ethane as well as propane and the heavier hydrocarbons. The Chaco Plant receives and processes natural gas from the San Juan Gathering System (the "Gathering System"), an over 5,500 mile natural gas gathering system in New Mexico owned and operated by an Affiliate of El Paso Field Services, L.P. ("Field Services"). II. Current Status of Chaco Plant As of October 2001, the Borrower acquired certain interests, indirectly, in the Chaco Plant through the consummation of the following transactions: 1. Delos Offshore Company, L.L.C. ("Delos"), a Restricted Subsidiary of the Borrower, purchased all of the notes and certificates issued by The Chaco Liquids Plant Trust, a Massachusetts business trust (the "Trust"), to the sale-leaseback lenders in connection with the sale-leaseback financing transaction that Field Services put in place in 1995; 2. The effect of the purchase of such notes and certificates was that Delos became the beneficiary of the Trust and acquired title to the Chaco Plant subject to the existing lease documents; 3. Delos became the agent for the Trust; 4. El Paso Energy Partners Operating Company, L.L.C., another Restricted Subsidiary of the Borrower, was appointed as trustee of the Trust, replacing State Street Bank and Trust Company; 5. The Trust was designated as a Restricted Subsidiary of the Borrower which designation was consented by the Lenders pursuant to the First Amendment to the Existing Credit Agreement dated as of October 10, 2001, and is therefore a Subsidiary Guarantor and has pledged its assets as collateral for the Obligations; 6. Delos and Field Services entered into a Tolling Agreement under which (a) Field Services dedicated all of the natural gas received into the Gathering System to the Chaco Plant for processing (except for certain amounts of natural gas that were previously dedicated to the nearby Conoco/Blanco Plant, and certain other amounts of natural gas that are used for fuel use, farm taps and lift gas, or temporarily offloaded due to capacity restraints on the Gathering System pursuant to terms of existing gathering agreements), (b) Field Services became obligated to attempt to acquire additional processing rights for Exhibit O - 1

gas gathered by the Gathering System, and (c) gas delivered to the Chaco Plant by Field Services has a processing priority over other gas; and 7. Field Services personnel continue to operate and provide other services related to the Chaco Plant. Exhibit O - 2

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 22

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 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. Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Loans shall be made pro rata according to the respective outstanding principal amounts of the Loans then held by the Lenders. All payments (including prepayments) to be made by the Borrower hereunder, 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 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 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 23

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. 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: (i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Note, 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 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 all amounts payable hereunder. 24

(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 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) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding, in the case of the Administrative Agent, the Collateral Agent and each Lender, net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent, the Collateral Agent or such Lender, as the case may be, as a result of a present or former connection between the jurisdiction of the government or taxing authority imposing such tax and the Administrative Agent, the Collateral Agent or such Lender (excluding a connection arising solely from the Administrative Agent, the Collateral Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement) or any political subdivision or taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, duties, charges, fees, deductions and withholdings being hereinafter called "Taxes"). If any Taxes are required to be withheld from any amounts payable to the Administrative Agent, the Collateral Agent or any Lender hereunder, the amounts so payable to the Administrative Agent, the Collateral Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent, the Collateral Agent or such Lender (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement. Whenever any Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account, for the account of the Collateral Agent or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent, the Collateral Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent, the Collateral Agent or any Lender as a result of any such failure. The agreements in this Section 4.10 shall survive the termination of this Agreement and the payment of all amounts payable hereunder. (b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall: 25

(i) deliver to the Borrower and the Administrative Agent (A) two duly completed copies of United States Internal Revenue Service Form W8-ECI or W8-BEN, or successor applicable form, as the case may be, and (B) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be; (ii) deliver to the Borrower and the Administrative Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (iii) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Administrative Agent; unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Administrative Agent. Such Lender shall certify (i) in the case of a Form W8-ECI or W8-BEN, that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an exemption from United States backup withholding tax. 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 26

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. Section 4.13 Acquisition; Disposition; Redesignation. If the Borrower or any of its Subsidiaries that is a Restricted Subsidiary acquires any Acquired Business or makes any sale or disposition of any assets or property having a value in excess of $5,000,000 pursuant to subsection 8.6(b) or there is a Redesignation of any Subsidiary during any Calculation Period, Consolidated EBITDA, Consolidated Tangible Net Worth, Consolidated Interest Expense, 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. Section 4.14 Redesignated Senior Indebtedness. The Borrower hereby designates all Obligations of the Borrower and its Subsidiaries under this Agreement and the other Loan Documents as "Designated Senior Debt," as such term is defined in the Senior Subordinated Note Indentures.

Except as set forth on Schedule 5.1, during the period from June 30, 2002 to and including the Restatement Closing Date there has been no sale, transfer or other disposition by the Borrower or any of its consolidated Subsidiaries of any material part of its business or property and no purchase or other acquisition of any business or property (including any capital stock of any other Person) material in relation to the consolidated financial condition of the Borrower and its consolidated Subsidiaries at June 30, 2002.

This Agreement constitutes, and each Note and each other Loan Document to which the Borrower is a party when executed and delivered will constitute, a legal, valid and binding obligation of the Borrower enforceable against the Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of 29

creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). (b) Each of the Subsidiary Guarantors has the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and has taken all necessary action to authorize the execution, delivery and performance of the Loan Documents to which it is a party.

Each of the Loan Documents to which such Subsidiary Guarantor is a party will be duly executed and delivered on behalf of such Subsidiary Guarantor. Each Loan Document to which such Subsidiary Guarantor is a party will, when executed and delivered, constitute a legal, valid and binding obligation of such Subsidiary Guarantor enforceable against such Subsidiary Guarantor in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). Section 5.5 No Legal Bar.

Section 5.6 No Material Litigation. Except as set forth on Schedule 5.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any of its Subsidiaries, or, to the best knowledge of the Borrower, any Joint Venture any of the interests in which is owned by a Subsidiary of the Borrower that is a Restricted Subsidiary, or against any of its or their respective properties or revenues (a) with respect to this Agreement, the Notes or any of the other Loan Documents or any of the transactions contemplated hereby or thereby, or (b) which could reasonably be expected to have a Material Adverse Effect. Section 5.7 No Default.

payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Lender, the Administrative Agent, the Collateral Agent, the Co-Syndication Agents, the Co-Documentation Agents, and their Affiliates, and their respective directors, officers, employees, agents and advisors (each such person being called an "Indemnified Party") harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments and suits, and reasonable costs, expenses or disbursements, of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement and the other Loan Documents, the use of the proceeds of the Loans, including the use and reliance on electronic, telecommunications or other information or transmission systems in connection with the Loan Documents (all the foregoing in this clause (d), collectively, the "indemnified liabilities"), REGARDLESS OF WHETHER OR NOT SUCH INDEMNIFIED LIABILITIES ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AN INDEMNIFIED PARTY, provided, that the Borrower shall have no obligation hereunder to an Indemnified Party with respect to indemnified liabilities arising from (i) the gross negligence or willful misconduct of such Indemnified Party or (ii) legal proceedings commenced against an Indemnified Party by any security holder or creditor thereof arising out of and based upon rights afforded any such security holder or creditor solely in its capacity as such. The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder. Section 11.6 Successors and Assigns; Participations; Purchasing Lenders. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent and the Collateral Agent and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Collateral Agent, and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: (A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to an assignee that is a Lender immediately prior to giving effect to such assignment, an Affiliate of such a Lender, or, if an Event of Default has occurred and is continuing, any other assignee; and 68

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender immediately prior to giving effect to such assignment. (ii) Assignments shall be subject to the following additional conditions: (A) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender's rights and obligations under this Agreement; (B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $2,500; and (C) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 4.9, 4.10, 4.11 and 11.5 to the extent relating to matters during the time it was a Lender). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section to the extent complying with Section 11.6(c) or otherwise as void and of no force and effect. (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Collateral Agent, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at any reasonable time and from time to time upon reasonable prior notice. (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such 69

assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption, give notice of such Assignment and Assumption to the Borrower, and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent, or the Collateral Agent, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of the Loans owing to it); provided that (A) such Lender's obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Collateral Agent, and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. 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 to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Document, and no Lender shall be entitled to create in favor of any Participant any right to vote on, consent to or approve any matter relating to any Loan Document; 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 clause (i), (ii) or (v) of the proviso to Section 11.1 that directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.9, 4.10 and 4.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.5 as though it were a Lender, provided such Participant agrees to be subject to Section 11.7 as though it were a Lender. (ii) A Participant shall not be entitled to receive any greater payment under Section 4.9, 4.10 or 4.11 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(b) as though it were a Lender. (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 70

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 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(f), 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 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 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, 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 (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 71

provision to the contrary in this Agreement, 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, any of the other Loan Documents or any other document pertaining hereto 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 hereunder 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 Article 5069-1D.001 et seq., as amended, of the Texas Revised Civil Statutes 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 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 hereunder 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 11.13 Submission To Jurisdiction; Waivers. The Borrower hereby irrevocably and unconditionally: (a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and 72

enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof; (b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same; (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrower at its address set forth in Section 11.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto; (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and (e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary or punitive damages (including, without limitation, damages arising from the use of electronic, telecommunications or other information transmissions systems in connection with the Loan Documents). 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 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, 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 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 employee, officer, director, accountant, attorney or consultant of such Person, or any examiner or other Governmental Authority, (b) that has been or is made public by EPEPC, EPEPFC, EPN 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, (c) that is or becomes available to any such Person from a third party on a non-confidential basis, (d) that is required to be disclosed 73

by any Requirement of Law, including to any bank examiners or regulatory authorities, (e) that is required to be disclosed by any court, agency, arbitrator or legislative body, (f) to any Transferee or proposed Transferee, or (g) to any rating agency to the extent required in connection with any rating to be assigned to such Lender. 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. Section 11.17 ACKNOWLEDGEMENT OF NO CLAIMS, OFFSETS OR DEFENSES; RELEASE BY THE LOAN PARTIES. BORROWER, ON BEHALF OF ITSELF AND EACH OF THE OTHER LOAN PARTIES, ACKNOWLEDGES THAT NO LOAN PARTY NOR ANY OF THEIR RESPECTIVE OWNERS, DIRECTORS, SUCCESSORS, ASSIGNS, AGENTS, OFFICERS, EMPLOYEES, AND REPRESENTATIVES (COLLECTIVELY, THE "BORROWER AFFILIATES PARTIES") HAS ANY CLAIM, DEMAND, RIGHT OF OFFSET, CAUSE OF ACTION IN LAW OR IN EQUITY, LIABILITY OR DAMAGES OF ANY NATURE WHATSOEVER, WHETHER FIXED OR CONTINGENT (HEREINAFTER COLLECTIVE CALLED "CLAIMS") THAT COULD BE ASSERTED IN CONNECTION WITH, OR WHICH WOULD IN ANY OTHER MANNER BE RELATED TO, THE EXISTING EPNHC CREDIT AGREEMENT OR ANY PROMISSORY NOTES OR OTHER AGREEMENTS, TRANSACTIONS OR OTHER ACTIONS PRIOR TO THE DATE HEREOF INVOLVING ANY OF THE BORROWER AFFILIATED PARTIES AND LENDERS ("THE PRIOR AGREEMENTS AND ACTIVITIES"). 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 CORPORATIONS 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. 74

Section 11.18 Releases. (a) At such time as the Loans and any other obligations under this Agreement shall have been paid in full, 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 performance of any act by any party, and all rights to the Collateral shall revert to the respective Loan Parties. At the request and expense of any Loan Party following any such termination, the Collateral Agent shall deliver to such Loan Party any Collateral held by the Collateral Agent under the Security Documents, and execute and deliver to such Loan Party such documents as such Loan Party shall reasonably request to evidence such termination. (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, 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 Security Document in the event that all the Equity Interests of such Loan Party shall be sold, transferred or otherwise disposed of in a transaction permitted by 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 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 11.19 Intercreditor Agreement. Each Lender (including each assignee which becomes a Lender pursuant to Section 11.6) consents and agrees to the provisions of the Intercreditor Agreement, including the indemnity provisions set forth in Section 7 thereof. The Lenders also hereby authorize and appoint the Administrative Agent to act as their agent with respect to the execution and delivery of the Intercreditor Agreement. ARTICLE XII THE COLLATERAL AGENT Section 12.1 Appointment. Each Lender hereby irrevocably designates and appoints JPMorgan as the Collateral Agent of such Lender under this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes JPMorgan, as the Collateral Agent for such Lender, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Collateral Agent shall not have any 75

duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Collateral Agent. Section 12.2 Delegation of Duties. The Collateral Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care. Section 12.3 Exculpatory Provisions. Neither the Collateral Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for its or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Collateral Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower. 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 EPN Group 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 EPN Group Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders. 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 76

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 EPN Group Administrative Agents acting jointly or the Required EPN Group 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 EPN Group 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 EPN Group 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 EPN Group Lenders shall appoint from among the EPN Group Lenders a successor agent for the EPN Group 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. After any retiring Collateral Agent's resignation as Collateral 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 Collateral Agent under this Agreement and the other Loan Documents. Section 12.8 Amendment. None of the terms or provisions of this Article XII may be amended, modified or waived without the written consent of the then Collateral Agent. 77

SCHEDULE 5.1 GUARANTEE OBLIGATIONS, CONTINGENT LIABILITIES AND DISPOSITIONS I. Guarantee Obligations and Contingent Liabilities: 1. None. II. Dispositions or Acquisitions of Business Properties since June 30, 2002: 2. None. Annexes and Schedules

SCHEDULE 5.6 MATERIAL LITIGATION In 1997, EPN, along with several subsidiaries of El Paso Corporation, 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 under report 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. 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. EPN 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. 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 Quinque complaint was transferred to the same court handling the Grynberg complaint and has now been sent back to Kansas State Court for further proceedings. A motion to dismiss this case is pending. Under the terms of EPN's agreement to acquire the Borrower's assets, subsidiaries of El Paso Corporation have agreed to indemnify EPN against all obligations related to existing legal matters at the acquisition date, including the legal matters involving Leapartners, L.P., City of Edinburg (the "City") and Houston Pipe Line Company LP discussed below. During 2000, Leapartners, L.P. filed a suit against an affiliate of El Paso Corporation and others in the District Court of Loving County, Texas, alleging a breach of contract to gather and process gas in areas of western Texas related to an asset now owned by the Borrower. In May 2001, the court ruled in favor of Leapartners, L.P. and entered a judgment against El Paso Field Services, L.P. of approximately $10 million. El Paso Field Services, L.P. has filed an appeal with the Eighth Court of Appeals in El Paso, Texas. Also, EPGT Texas Pipeline, now owned by the Borrower, is involved in litigation with the City concerning the City's claim that EPGT Texas Pipeline was required to pay pipeline franchise fees under a contract the City had with Rio Grande Valley Gas Company, which was previously owned by EPGT Texas Pipeline and is now owned by Southern Union Gas Company ("Southern Union"). An adverse judgment against Southern Union and EPGT Texas Pipeline was rendered in December 1998 and upheld for breach of contract, holding both EPGT Texas Pipeline 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 EPGT Texas Pipeline and Southern Union's entities that were not parties to the contract with the City. EPGT Texas Pipeline has appealed this case to the Texas Supreme Court seeking reversal of the judgment rendered against EPGT Texas Pipeline. The City seeks a remand to the trial court of its claim of tortious interference against EPGT Texas Pipeline. The briefing before the Texas Supreme Court is complete. Annexes and Schedules

In December 2000, a 30-inch natural gas pipeline jointly owned now by the Borrower and Houston Pipe Line Company LP ruptured in Mont Belvieu, Texas, near Baytown, resulting in substantial property damage and minor physical injury. The Borrower is the operator of the pipeline. Lawsuits have been filed in state district court in Chambers County, Texas. An additional landowner has intervened in the Chambers County suits, as well as the homeowners' insurers. The suits seek recovery for physical pain and suffering, mental anguish, physical impairment, medical expenses, and property damage. Houston Pipe Line Company LP has been added as an additional defendant. In accordance with the terms of the operating agreement, the Borrower has agreed to assume the defense of and to indemnify Houston Pipe Line Company LP in the litigated cases. Discovery is proceeding and trial is set for November 2002. As discussed above, any obligation to Houston Pipe Line Company LP incurred by the Borrower is indemnified by subsidiaries of El Paso Corporation. Annexes and Schedules

Interest shall be payable in arrears on each Interest Payment Date commencing on the first such date to occur after the date hereof, provided that interest accruing pursuant to subsection 4.4(c) of the Credit Agreement shall be payable on demand. In no event shall the interest payable hereon, whether before or after maturity, exceed the maximum interest which, under applicable law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how interest accrues hereon. The holder of this Note is authorized to record the date, type and amount of each Loan made by the Lender pursuant to Section 2.1 of said Credit Agreement, each continuation thereof, each conversion of all or a portion thereof to another type, the date and amount of each payment or prepayment of principal with respect thereto, and, in the case of Eurodollar Loans, the length of each Interest Period with respect thereto, on the schedules annexed hereto and made a part hereof, or on a continuation thereof which shall be attached hereto and made a part hereof, which recordation shall constitute prima facie evidence of the accuracy of the information recorded in the absence of manifest error; provided that failure by the Lender to make any such recordation on this Note shall not affect the obligations of the Borrower under this Note or said Credit Agreement.
