ITEM 5. OTHER EVENTS This filing is to, among other things, update our current risk factors discussion. DUE TO OUR SIGNIFICANT RELATIONSHIPS WITH EL PASO CORPORATION, ADVERSE DEVELOPMENTS CONCERNING EL PASO CORPORATION COULD ADVERSELY AFFECT US, EVEN IF WE HAVE NOT SUFFERED ANY SIMILAR DEVELOPMENTS. Through its subsidiaries, El Paso Corporation owns 100 percent of our general partner and has historically, with its affiliates, employed the personnel who operate our businesses. El Paso Corporation is a significant stakeholder in our limited partner interests, and as with many other large energy companies, is a significant customer of ours. The outstanding senior unsecured indebtedness of El Paso Corporation has been downgraded to below investment grade, at least in part, as a result of the outlook for the consolidated business of El Paso Corporation and its need for liquidity. In the event that El Paso Corporation's liquidity needs are not satisfied, El Paso Corporation could be forced to seek protection from its creditors in bankruptcy. Although we are making efforts to implement new procedures and other mechanisms to better balance the risks and rewards of our significant relationships with El Paso Corporation and its affiliates, if El Paso Corporation continues to suffer financial stress, we may be adversely affected, even if we have not suffered any similar developments. WE WILL BE ADVERSELY AFFECTED IF WE CANNOT NEGOTIATE REPLACEMENT CONTRACTS ON COMMERCIALLY REASONABLE TERMS FOR TRANSPORTATION AND STORAGE SALES TO EL PASO MERCHANT ENERGY, A SUBSIDIARY OF EL PASO CORPORATION. El Paso Corporation announced on November 8, 2002 its intentions to exit the energy trading business. During the year ended December 31, 2002, transportation and storage contracts with El Paso Merchant Energy accounted for $90 million in revenue. If we are unable to successfully negotiate replacement contracts with unaffiliated parties, or if the replacement contracts are on less favorable terms, the effect on us will be adverse. ITEM 7.

ITEM 9. REGULATION FD DISCLOSURE In accordance with General Instruction B.2. of Form 8-K, the following information shall not be deemed `filed' for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such a filing. Set forth below is additional information relating to us, our operations and our relationship with El Paso Corporation. OUR GENERAL PARTNER El Paso Energy Partners Company, a Delaware corporation, is our sole general partner. The business and affairs of our general partner are managed by a board of directors, comprised of two management directors who are also our executive officers and three independent directors who meet the independent director requirements established by the NYSE and the Sarbanes-Oxley Act of 2002. We recently announced that the size of the board will be increased by the addition of two more independent directors. Through its board of directors, our general partner manages our day-to-day operations. Our corporate governance structure and independence initiatives The market is requesting that public companies institute dramatic governance changes designed to achieve independence, qualitatively and quantitatively. Some of the more immediate and fundamental proposed changes establish and require a higher standard for determining director independence and require a greater percentage of the members of the board to be independent. For example, under rules recently proposed by the NYSE: o at least a majority of the members of the board of a listed company must be "independent directors;" o each public company board must form several specific committees--audit, governance and compensation--that must be comprised entirely of independent directors; and o the chairperson of the audit committee must be a "financial expert."

The Securities and Exchange Commission and the NYSE have developed definitions and other guidance to help establish minimum qualifications for "independent directors" and "financial experts." We are in compliance with all of these rules, regulations and standards that apply to us. We continually strive to improve our corporate governance model. We recently identified and evaluated a number of changes we could make to our corporate structure, including a number of new procedures and other mechanisms we could implement, to better address potential conflicts of interest and to better balance the risks and rewards of significant relationships with our affiliates. With respect to the potential changes we identified, which we refer to as Independence Initiatives, we have already implemented the following: o reconstituted our general partner's board of directors with at least a majority of non-management, independent directors; o established a governance and compensation committee of our general partner's board of directors consisting solely of independent directors; and o significantly reduced the percentage of revenue we derive from affiliates of El Paso Corporation. We are in the process of implementing the following Independence Initiatives: o seeking financial assurances from El Paso Corporation and its affiliates regarding our existing customer/contractual relationships with them; o adding two more independent directors to our general partner's board of directors; o reorganizing our general partner, further reducing our interrelationships with El Paso Corporation, into a Delaware limited liability company that will be required to have: o no material assets other than its interests in us; o no material operations other than those relating to our operations; o no material debt or other obligations other than those owed to us or our creditors; o no material liens other than those securing obligations owed to us or our creditors; and o no employees; o changing our name; and

o negotiating several agreements that could partially mitigate our risks associated with our ongoing contractual arrangements with El Paso Corporation or any of its subsidiaries, including a master netting agreement and a resource support agreement. We must receive approval from our general partner's board of directors and from El Paso Corporation prior to consummating the reorganization of our general partner and executing the master netting agreement and resource support agreement.. Under the partnership agreement, our general partner has the responsibility to, among other things, manage and operate our assets. We have no employees today, a condition that is common among MLPs. Although this arrangement has worked well for us in the past and continues to work well for us, we are evaluating the direct employment of the personnel who manage the day-to-day operations of our assets. OUR RELATIONSHIP WITH EL PASO CORPORATION El Paso Corporation, an NYSE-listed company, is a leading provider of natural gas services and the largest pipeline company in North America. Through its subsidiaries, El Paso Corporation: o owns 100 percent of our general partner, which means that, historically, El Paso Corporation and its affiliates have employed the personnel who operate our businesses. We reimburse our general partner and its affiliates for the costs they incur on our behalf, and we pay our general partner its proportionate share of distributions -- relating to its one percent general partnership interest and the related incentive distributions -- we make to our partners each calendar quarter. o is a significant stakeholder in us -- it owns approximately 26.5 percent, or 11,674,245, of our common units, all 10,937,500 of our newly issued Series C units, which we issued in November 2002 for $350 million, all 125,392 of our outstanding Series B preference units (with a liquidation value at February 28, 2003 of $160 million), and our one percent general partner interest. As holders of some of our common units and all of our Series C units, subsidiaries of El Paso Corporation receive their proportionate share of distributions we make to our partners each calendar quarter. o is a customer of ours. As with other large energy companies, we have entered into a number of contracts with El Paso Corporation and its affiliates. o has in the past publicly announced its intention to use us as its primary vehicle for growth and development of its midstream energy business; however, El Paso Corporation is neither contractually nor legally bound to use us as its primary vehicle for growth and development of midstream energy assets, and may reconsider its relationship with us at any time, without notice.

Our relationship with El Paso Corporation has contributed significantly to our past growth, and we have important ongoing contractual arrangements with El Paso Corporation and some of its subsidiaries. However, we are a stand-alone operating company with significant assets and operations. Our assets, operations and financial condition are separate and independent from those of El Paso Corporation. Our credit facilities and other financing arrangements do not contain cross default provisions or other triggers tied to El Paso Corporation's financial condition or credit ratings. Nonetheless, due to our relationship with El Paso Corporation, adverse developments concerning El Paso Corporation could adversely affect us, even if we have not suffered any similar developments. The outstanding senior unsecured indebtedness of El Paso Corporation has been downgraded to below investment grade and is currently rated Caa1 by Moody's Investors Service (Moody's) and B by Standard & Poor's (S&P's). These downgrades are a result, at least in part, of the outlook for the consolidated business of El Paso Corporation and its need for liquidity. In the event that El Paso Corporation's liquidity needs are not satisfied, El Paso Corporation could be forced to seek protection from its creditors in bankruptcy. We have publicly disclosed our efforts to further distinguish ourselves from El Paso Corporation. As a result of this announcement, and investors' perception that general partner investments are trading at lower than historical valuations, various parties have expressed an interest in purchasing all or a portion of our general partner. We have been entrusted by the owner of our general partner to meet with a limited number of such investors to gauge the level of their interest and will report back to El Paso Corporation on the outcomes of these meetings. El Paso Corporation has the sole responsibility of determining the ultimate ownership status of the general partner interest. We have publicly acknowledged that we are meeting with parties interested in acquiring an equity stake in the general partner but cannot confirm that such interest will result in firm proposals or, if such firm proposals are received, that El Paso Corporation will consider such proposals. If El Paso Corporation sells 50 percent or more of its interest in our general partner without obtaining consent from our lenders, we will experience a "change in control" under our credit agreements and indentures, which will effectively cause all amounts outstanding under those debt instruments to become due. As discussed previously, we have implemented, and are in the process of implementing, a number of Independence Initiatives that are designed to help us better manage the rewards and risks relating to our relationship with El Paso Corporation. However, even in light of these Independence Initiatives or any other arrangements, we may still be adversely affected if El Paso Corporation continues to suffer financial stress.

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 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 outstanding principal amounts of the Loans then held by the Lenders. All payments (including prepayments) to be made by the Borrower hereunder and under the Notes, whether on account of principal, interest, fees or otherwise, shall be made without set off or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Administrative Agent's office specified in Section 11.2, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the 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 30

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 the Closing 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 the Closing 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 the Closing 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 the Closing 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 the Closing Date, the Administrative Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to Alternate Base Rate Loans hereunder, on demand, from the Borrower. Section 4.8 Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Alternate Base Rate Loans to Eurodollar Loans shall forthwith be cancelled and (b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Alternate Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 4.11. Section 4.9 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: 31

(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 the Notes, the Loans 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 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, the Notes and the other Loan Documents 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 32

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, the Notes or the other Loan Documents) 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, under the Notes or the other Loan Documents, 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, the Loans 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; 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- 33

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) 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 34

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 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. Section 4.15 Securities Demand. The Initial Lenders shall have the right to make demand on the Borrower and the Co-Borrower to issue debt securities pursuant to the terms and conditions of the Securities Demand Letter Agreement dated as of the date hereof by and among the Borrower and the Initial Lenders. ARTICLE V REPRESENTATIONS AND WARRANTIES To induce the Administrative Agent and the Lenders to enter into this Agreement, the Borrower hereby represents and warrants to the Administrative Agent and each Lender that: Section 5.1 Financial Condition. (a) The consolidated balance sheet of the Borrower and its consolidated Subsidiaries as at December 31, 2001, and the related consolidated statements of operations and of cash flows for the fiscal year ended December 31, 2001, reported on by PricewaterhouseCoopers LLP, copies of which have heretofore been furnished to each Lender, present fairly the consolidated financial condition of the Borrower and its consolidated Subsidiaries as at such date, and the consolidated results of their operations and their consolidated cash flows for the year then ended. The unaudited consolidated balance sheet of the Borrower and its consolidated Subsidiaries as at September 30, 2002 and the related consolidated statements of operations and of cash flows for the nine months ended September 30, 2002, copies of which have heretofore been furnished to each Lender, present fairly the consolidated financial condition of the Borrower and its consolidated Subsidiaries as at such date, and the consolidated results of their operations and their consolidated cash flows for the nine-month period then ended. All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by such accountants and as disclosed therein and, with respect to the September 30, 2002 financial statements, for the absence of footnotes and year-end adjustments). Except as set forth on Schedule 5.1 or as permitted by subsection 8.4(c), neither the Borrower nor any of its consolidated Subsidiaries had, at the date of the most recent balance sheet referred to above, any material Guarantee Obligation, contingent liability or liability for taxes, or any long-term lease or unusual forward or long-term commitment, including, without 35

limitation, any interest rate or foreign currency swap or exchange transaction, which is not reflected in the foregoing statements or in the notes thereto. Except as set forth on Schedule 5.1, during the period from September 30, 2002 to and including the 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 September 30, 2002. (b) The Projections delivered to the Administrative Agent and the Lenders prior to the Closing Date have been prepared in good faith and are based on assumptions believed by the Borrower to be reasonable at the time made. On the Closing Date, Borrower believed that the Projections were reasonable; it being recognized by the Administrative Agent and the Lenders, however, that projections as to future events are not to be viewed as facts and that the actual results during the period or periods covered by the Projections may differ from the projected results and such differences may be material. Section 5.2 No Change. Since September 30, 2002 (but for this purpose, assuming that the Transaction had occurred immediately prior thereto), (a) there has been no development or event which has had or could reasonably be expected to have a Material Adverse Effect and (b) no dividends or other distributions have been declared, paid or made upon the Capital Stock of the Borrower except as permitted by Section 8.7, nor has any of the Capital Stock of the Borrower been redeemed, retired, purchased or otherwise acquired for value by the Borrower or any of its Subsidiaries. For the avoidance of doubt, the consummation of the Transaction does not give rise to a Material Adverse Effect. Section 5.3 Existence; Compliance with Law. Each of the Borrower and its Subsidiaries (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign corporation, limited partnership or limited liability company, as the case may be, and, where applicable, in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification and (d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. Section 5.4 Power; Authorization; Enforceable Obligations. (a) The Borrower has the power and authority, and the legal right, to make, deliver and perform this Agreement, the Notes and the other Loan Documents to which it is a party and to borrow hereunder and has taken all necessary action to authorize the borrowings on the terms and conditions of this Agreement and the Notes and to authorize the execution, delivery and performance of this Agreement, the Notes and the other Loan Documents to which it is a party. 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. This Agreement has been, and each Note has been or will be, duly 36

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). (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. 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 the Loan Documents to which such Subsidiary Guarantor 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 the Borrower or 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 the Borrower or 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 the Borrower or 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. 37

Section 5.8 Ownership of Property; Liens. Each of the Borrower and its Restricted Subsidiaries has good record and marketable title in fee simple to, or a valid leasehold interest in, all its real property necessary for its operations as then conducted, and good title to, or a valid leasehold interest in, all its other property, and none of such property necessary for its operations as then conducted is subject to any Lien except as permitted by Section 8.3. Section 5.9 Intellectual Property. The Borrower and each of its Restricted Subsidiaries owns, or is licensed to use, all trademarks, tradenames, copyrights, technology, know-how and processes necessary for the conduct of its business as currently conducted except for those the failure to own or license which could not have a Material Adverse Effect (the "Intellectual Property"). 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 5.10 No Burdensome Restrictions. The Borrower, in good faith, does not believe any Requirement of Law or Contractual Obligation of the Borrower or any of its Restricted Subsidiaries could reasonably be expected to have a Material Adverse Effect. Section 5.11 Taxes. Each of the Borrower and its Subsidiaries has filed or caused to be filed all tax returns which, to the knowledge of the Borrower, are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or its Subsidiaries, as the case may be); no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge. Section 5.12 Federal Regulations. No part of the proceeds of any Loans will be used for "purchasing" or "carrying" any "margin stock" within the respective meanings of each of the quoted terms under Regulation U of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect or for any purpose which violates the provisions of the Regulations of such Board of Governors. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form U-1 referred to in said Regulation U. Section 5.13 ERISA. No Loan Party has or is a party to, or has any matured or contingent obligations under, any Plans. Section 5.14 Investment Company Act; Other Regulations. The Borrower is not an "investment company", or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended. The Borrower is not subject to 38

regulation under any Federal or State statute or regulation which limits its ability to incur Indebtedness. Section 5.15 Subsidiaries. The Persons set forth on Schedule 5.15 constitute all of the Subsidiaries of the Borrower and all Joint Ventures in which the Borrower owns any direct or indirect interest, as of the Closing Date (both before and after the Reorganization Transactions as indicated in such Schedule) and the percentage of the equity interests owned by the Borrower in each such Person as of such date (both before and after the Reorganization Transactions as indicated in such Schedule). Except for Arizona Gas, EPN Arizona and MIAGS, each of the Subsidiaries listed on Schedule 5.15 is as of the Closing Date a Restricted Subsidiary. Section 5.16 Purpose of Loans.

Except as set forth on Schedule 5.17: (a) To the best knowledge of the Borrower, the Properties do not contain, and have not previously contained, any Materials of Environmental Concern in amounts or concentrations which (i) constitute or constituted a violation of, or (ii) give rise to liability under, any Environmental Law, except in either case insofar as such violation or liability, or any aggregation thereof, could not reasonably be expected to result in the payment of a Material Environmental Amount. (b) To the best knowledge of the Borrower, the Properties and all operations at the Properties are in compliance, and have in the period commencing six months prior to the date hereof been in compliance, in all material respects with all applicable Environmental Laws, and there is no contamination at, under or about the Properties or violation of any Environmental Law with respect to the Properties or the business operated by the Borrower or any of its Subsidiaries or any Joint Venture (the "Business") which could materially interfere with the continued operation of any material Property or which could reasonably be expected to have a Material Adverse Effect. (c) Neither the Borrower nor any of its Subsidiaries nor, to the best knowledge of the Borrower, any Joint Venture has received any notice of violation, alleged violation, non-compliance, liability or potential liability regarding environmental matters or compliance with Environmental Laws with regard to any of the Properties or the Business, nor does the Borrower have knowledge or reason to believe that any such notice will be received or is being threatened except insofar as such notice or threatened notice, or any aggregation thereof, does not involve a matter or matters that is or could reasonably be expected to result in the payment of a Material Environmental Amount. (d) To the best knowledge of the Borrower, Materials of Environmental Concern have not been transported or disposed of from the Properties in violation of, or in a manner or to a location which could reasonably be expected to give rise to liability under, any Environmental Law, nor have any Materials of Environmental Concern been generated, treated, stored or disposed of at, on or under any of the Properties in violation of, or in a manner that 39

Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any 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 Administrative Agent. Section 10.2 Delegation of Duties. The Administrative 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.

Neither the Administrative 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 Administrative 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, the Notes or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder.

The Administrative 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 70

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 Administrative Agent. The Administrative 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 Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement, the Notes and the other Loan Documents in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Notes. Section 10.5 Notice of Default.

In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. Section 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 71

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. Section 10.7 Indemnification. The Lenders agree to indemnify the Administrative 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 Loan 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 Notes and Loans) be imposed on, incurred by or asserted against the Administrative 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 Administrative 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 Administrative Agent's gross negligence or willful misconduct. The agreements in this Section 10.7 shall survive the payment of the Notes, Loans 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, 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. The terms "Lender," "Lenders," and similar terms shall include the Administrative Agent in its individual capacity. Section 10.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 10 days' written notice to the Lenders. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term "Administrative Agent" shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Notes. 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 "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 72

identified as a "co-syndication agent" or a "documentation agent" shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking any action hereunder.

execution of, and any amendment, supplement or modification to, this Agreement 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, 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 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 Documentation Agent, 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 (i) arising from the gross negligence or willful misconduct of such Indemnified Party or (ii) that are found by a final, non-appealable judgment of a court to arise solely from the reliance by one or more third-parties to their detriment on false or misleading information (the "Delivered Information") provided directly to such third-party by such Indemnified Party or its Affiliates, but such Delivered Information was not provided by, or based on information provided by, the Borrower or its Affiliates or advisors to such Indemnified Party nor was such Delivered Information available to (or based on information available to) such Indemnified Party from a publicly available source. The agreements in this Section shall survive repayment of the Notes and 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 75

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 or delayed) 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 any Lender, or, if a Default or an Event of Default has occurred and is continuing, any other assignee; and 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 $3,500; C. no such assignment to an assignee (other than any Lender, and Approved Fund or any Affiliate of any Lender) shall be in an aggregate principal amount less than $2,000,000; and D. 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 76

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, 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 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 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 77

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. Section 11.7 Adjustments; Set-off. (a) If any Lender (a "benefited 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 benefited 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 benefited 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 benefited 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. 78

Section 11.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. Section 11.9 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Section 11.10 Integration. This Agreement and the other Loan Documents represent the agreement of the Borrower, the Administrative Agent, the Collateral Agent and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent, the Collateral Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents. Section 11.11 Usury Savings Clause. It is the intention of the parties hereto to comply with applicable usury laws (now or hereafter enacted); accordingly, notwithstanding any provision to the contrary in this Agreement, the Notes, any of the other Loan Documents or any other document related hereto, in no event shall this Agreement or any such other document require the payment or permit the collection of interest in excess of the maximum amount permitted by such laws. If from any circumstances whatsoever, fulfillment of any provision of this Agreement or of any other document pertaining hereto or thereto, shall involve transcending the limit of validity prescribed by applicable law for the collection or charging of interest, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances the Administrative Agent, the Collateral Agent and the Lenders shall ever receive anything of value as interest or deemed interest by applicable law under this Agreement, the Notes, any of the other Loan Documents or any other document pertaining hereto 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 and 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. 79

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 11.14 Acknowledgements. The Borrower hereby acknowledges that: 80

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement, the Notes and the other Loan Documents; (b) none of the Administrative Agent, the Collateral Agent nor any Lender has any fiduciary relationship with or duty to the Borrower or any other Loan Party arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent, 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, (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 CO-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.

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 AFFILIATED 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 EPN CREDIT AGREEMENT, THE 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 81

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.

(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. 82

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 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.

SCHEDULE 5.1 GUARANTEE OBLIGATIONS, CONTINGENT LIABILITIES AND DISPOSITIONS I. Guarantee Obligations and Contingent Liabilities: 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. II. Dispositions or Acquisitions of Business Properties since September 30, 2002: Other than the Transaction, none. Annexes and Schedules-4

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. Annexes and Schedules-5

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.

(m) Changes in Locations, Name, etc. The Grantor recognizes that financing statements pertaining to the Collateral have been or may be filed where the Grantor maintains any Collateral or is organized. Without limitation of any other covenant herein, the Grantor will not cause or permit (i) any change to be made in its name, identity or corporate structure or (ii) any change to (A) the identity of any warehouseman, common carrier, other third-party transporter, bailee or any agent or processor in possession or control of any Collateral or (B) the Grantor's jurisdiction of organization, unless the Grantor shall have first (1) notified the Collateral Agent and the EPN Group Lenders of such change at least thirty (30) days prior to the effective date of such change, and (2) taken all action reasonably requested by the Collateral Agent or any of the EPN Group Lenders for the purpose of maintaining the perfection and priority of the Collateral Agent's security interests under this Security Agreement. In any notice furnished pursuant to this subsection, the Grantor will expressly state that the notice is required by this Security Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of the Collateral Agent's security interest in the Collateral. 6. Collateral Agent's Appointment as Attorney-in-Fact. (a) Powers. The Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Grantor and in the name of the Grantor or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, the Grantor hereby gives the Collateral Agent the power and right, on behalf of the Grantor, without notice to or assent by the Grantor, to do the following: (i) to pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Security Agreement and to pay all or any part of the premiums therefor and the costs thereof; and Exhibit C-7

(ii) upon the occurrence and during the continuance of any Event of Default, (A) to direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to ask or demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any thereof and to enforce any other right in respect of any Collateral; (D) to defend any suit, action or proceeding brought against the Grantor with respect to any Collateral; (E) to settle, compromise or adjust any suit, action or proceeding described in clause (D) above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; and (F) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and the Grantor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's and the EPN Group Lenders' Liens thereon and to effect the intent of this Security Agreement, all as fully and effectively as the Grantor might do. The Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. (b) Other Powers. The Grantor also authorizes the Collateral Agent and the EPN Group Lenders, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) No Duty on Collateral Agent or EPN Group Lenders' Part. The powers conferred on the Collateral Agent and the EPN Group Lenders hereunder are solely to protect the Collateral Agent's and the EPN Group Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent or any of the EPN Group Lenders to exercise any such powers. The Collateral Agent and the EPN Group Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to the Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. 7. Performance by Collateral Agent of Grantor's Obligations. If the Grantor fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Security Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of the Collateral Agent incurred in connection with such performance or compliance, together with interest thereon at a rate per annum 3-1/2% above the Alternate Base Rate, shall be payable by the Grantor to the Collateral Agent on demand and shall constitute Obligations secured hereby. 8. Proceeds. It is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by the Grantor consisting of cash, checks and other near-cash items shall be held by the Grantor in trust for the Collateral Agent for the ratable benefit of the EPN Group Exhibit C-8

Lenders and the Marco Polo Lenders, segregated from other funds of the Grantor, and shall, forthwith upon receipt by the Grantor, be turned over to the Collateral Agent in the exact form received by the Grantor (duly indorsed by the Grantor to the Collateral Agent, if required), and (b) any and all such Proceeds received by the Collateral Agent (whether from the Grantor or otherwise) may, in the sole discretion of the Collateral Agent, be held by the Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders as collateral security for, and/or then or at any time thereafter may be applied by the Collateral Agent against, the Obligations (whether matured or unmatured), such application to be in such order as the Collateral Agent shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full and the Commitments shall have been terminated shall be paid over to the Grantor or to whomsoever may be lawfully entitled to receive the same. 9. Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the EPN Group Lenders and the Marco Polo Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any of the EPN Group Lenders or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any of the EPN Group Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Grantor, which right or equity is hereby waived or released. The Grantor further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at the Grantor's premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the EPN Group Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to the Grantor. To the extent permitted by applicable law, the Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any of the EPN Group Lenders arising out of the exercise by them of any rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be Exhibit C-9

deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the EPN Group Lenders to collect such deficiency. 10. Limitation on Duties Regarding Preservation of Collateral. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, any of the EPN Group Lenders, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Grantor or otherwise. 11. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 12. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 13. Paragraph Headings. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 14. No Waiver; Cumulative Remedies. Neither the Collateral Agent nor any of the EPN Group Lenders shall by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any of the EPN Group Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any of the EPN Group Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent or such EPN Group Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 15. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Grantor and the Collateral Agent, provided that any provision of this Security Agreement may be waived by the Collateral Agent in a written letter or agreement executed by the Collateral Agent or by facsimile Exhibit C-10

transmission from the Collateral Agent. This Security Agreement shall be binding upon the successors and assigns of the Grantor and shall inure to the benefit of the Collateral Agent and the EPN Group Lenders and their respective successors and assigns. This Security Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. 16. Notices. Notices hereunder may be given by mail or by facsimile transmission, addressed or transmitted to the Person to which it is being given at such Person's address or transmission number set forth, in the case of the Collateral Agent and the EPN Group Lenders, in the Credit Agreement, and in the case of the Grantor, under its signature below, and shall be effective (a) in the case of mail, 3 days after deposit in the postal system, first class postage pre-paid and (b) in the case of facsimile notices, when sent. The Grantor may change its address and transmission number by written notice to the Collateral Agent, and the Collateral Agent or any of the EPN Group Lenders may change its address and transmission number by written notice to the Grantor and, in the case of a any of the EPN Group Lenders, to the Collateral Agent. 17. Authority of Collateral Agent. The Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as among the Collateral Agent, the EPN Group Lenders, and the Marco Polo Lenders, be governed by the Credit Agreement, EPNHC Credit Agreement and the Marco Polo Financing Documents, and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantor, the Collateral Agent shall be conclusively presumed to be acting as agent for the EPN Group Lenders and the Marco Polo Lenders with full and valid authority so to act or refrain from acting, and the Grantor shall not be under any obligation, or entitlement, to make any inquiry respecting such authority.

Defined Terms. Unless otherwise defined herein, terms which are defined in the EPNHC Credit Agreement and used herein are so used as so defined. As used herein, "Obligations" shall mean the unpaid principal of and interest on (including, without limitation, interest accruing after the maturity of the Loans and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to EPNHC, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) the Notes and all other obligations and liabilities of EPNHC to the EPNHC Administrative Agent or the EPNHC Lenders, whether direct or indirect, absolute or contingent, due or to become due, or now existing or hereafter incurred, which may arise under, out of, or in connection with, the EPNHC Credit Agreement, the other Loan Documents and any other document made, delivered or given in connection therewith or herewith, whether on account of principal, interest, reimbursement obligations, fees, indemnities, costs, expenses (including, without limitation, all fees and disbursements of counsel to the EPNHC Exhibit D-1

The Guarantor hereby unconditionally and irrevocably guarantees to the EPNHC Administrative Agent, for the ratable benefit of the EPNHC Lenders, the prompt and complete payment and performance by EPNHC when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations.

This Guarantee shall remain in full force and effect until the Obligations are paid in full and the Commitments are terminated, notwithstanding that from time to time prior thereto EPNHC may be free from any Obligations. The Guarantor agrees that whenever, at any time, or from time to time, it shall make any payment to the EPNHC Administrative Agent or any of the EPNHC Lenders on account of its liability hereunder, it will notify the EPNHC Administrative Agent and such EPNHC Lenders in writing that such payment is made under this Guarantee for such purpose. No payment or payments made by EPNHC or any other Person or received or collected by the EPNHC Administrative Agent or any of the EPNHC Lenders from EPNHC or any other Person by virtue of any action or proceeding or any set-off or appropriation or application, at any time or from time to time, in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the Guarantor hereunder which shall, notwithstanding any such payment or payments received or collected from the Guarantor in respect of the Obligations, remain liable for the Obligations until the Obligations are paid in full the Commitments are terminated. 3. Right of Set-off.

Exhibit D-2

4. No Subrogation. Notwithstanding any payment or payments made by the Guarantor hereunder, or any set-off or application of funds of the Guarantor by the EPNHC Administrative Agent or any of the EPNHC Lenders, the Guarantor shall not be entitled to be subrogated to any of the rights of the EPNHC Administrative Agent or any of the EPNHC Lenders against EPNHC or any other Loan Party or against any collateral security or guarantee or right of offset held by the EPNHC Administrative Agent or any of the EPNHC Lenders for the payment of the Obligations, nor shall the Guarantor seek or be entitled to seek any contribution or reimbursement from EPNHC or any other Loan Party in respect of payments made by the Guarantor hereunder, until all amounts owing to the EPNHC Administrative Agent and the EPNHC Lenders by EPNHC or any other Loan Party on account of the Obligations are paid in full and the Commitments are terminated. So long as the Obligations remain outstanding, if any amount shall be paid by or on behalf of EPNHC or any Loan Party to the Guarantor on account of any of such subrogation rights, such amount shall be held by the Guarantor in trust, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the EPNHC Administrative Agent in the exact form received by the Guarantor (duly indorsed by the Guarantor to the EPNHC Administrative Agent, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the EPNHC Administrative Agent may determine. The provisions of this paragraph shall survive the term of this Guarantee and the payment in full of the Obligations and the termination of the Commitments. 5. Amendments, etc. with respect to the Obligations. The Guarantor shall remain obligated hereunder and under the other Loan Documents to which it is a party notwithstanding that, without any reservation of rights against the Guarantor, and without notice to or further assent by the Guarantor, any demand for payment of any of the Obligations made by the EPNHC Administrative Agent or any of the EPNHC Lenders may be rescinded by the EPNHC Administrative Agent or such EPNHC Lenders, and any of the Obligations continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the EPNHC Administrative Agent or any of the EPNHC Lenders, and the EPNHC Credit Agreement, any Notes, any other Loan Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the EPNHC Lenders (or the Required EPNHC Lenders, as the case may be) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the EPNHC Administrative Agent or any of the EPNHC Lenders for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the EPNHC Administrative Agent nor any of the EPNHC Lenders shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. 6. Guarantee Absolute and Unconditional. The Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the EPNHC Administrative Agent or any of the EPNHC Lenders upon this Guarantee or any other Loan Document or acceptance of this Guarantee or any other Loan Document; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guarantee and the other Loan Documents to which the Guarantor Exhibit D-3

is a party; and all dealings between EPNHC or the Guarantor, on the one hand, and the EPNHC Administrative Agent and the EPNHC Lenders, on the other, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee and the other Loan Documents to which the Guarantor is a party. The Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon EPNHC or the Guarantor with respect to the Obligations.

When the EPNHC Administrative Agent is pursuing its rights and remedies hereunder or any other Loan Document against the Guarantor, the EPNHC Administrative Agent or any of the EPNHC Lenders may, but shall be under no obligation to, pursue such rights and remedies as it may have against EPNHC or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the EPNHC Administrative Agent or any of the EPNHC Lenders to pursue such other rights or remedies or to collect any payments from EPNHC or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of EPNHC or any such other Person or of any such collateral security, guarantee or right of offset, shall not relieve the Guarantor of any liability hereunder or under any other Loan Document to which it is a party, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the EPNHC Administrative Agent and the EPNHC Lenders against the Guarantor. 7. Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the EPNHC Administrative Agent or any of the EPNHC Lenders upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of EPNHC or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, EPNHC or any substantial part of its property, or otherwise, all as though such payments had not been made. 8. Payments. The Guarantor hereby agrees that the Obligations will be paid to the EPNHC Administrative Agent without set-off or counterclaim in U.S. Dollars at the office of the EPNHC Administrative Agent located at One Chase Manhattan Plaza, 8th Floor, New York New York 10081. 9.

Severability. Any provision of this Guarantee 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.

11. Paragraph Headings. The paragraph headings used in this Guarantee are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 12. No Waiver; Cumulative Remedies. Neither the EPNHC Administrative Agent nor any of the EPNHC Lenders shall by any act (except by a written instrument pursuant to paragraph 13 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the EPNHC Administrative Agent or any of the EPNHC Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the EPNHC Administrative Agent or any of the EPNHC Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the EPNHC Administrative Agent or such EPNHC Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 13. Waivers and Amendments; Successors and Assigns; Governing Law.

become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to receive payment of and receipt for any and all moneys, claims and other amounts due and to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, drafts against debtors, assignments, verifications and notices in connection with accounts and other documents relating to the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against the Pledgor with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; and (G) generally, to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and the Pledgor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as the Pledgor might do. The Pledgor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. (b) The powers conferred on the Collateral Agent hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to the Pledgor, any Subsidiary or to any other member or partner of or owner of any limited or general partner interest, limited liability company interest or other equity interest in any Non-Corporate Subsidiary for any act or failure to act. (c) The Pledgor also authorizes the Collateral Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 of this Agreement, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. 9. Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing and to the extent permitted by applicable law, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Pledgor, any of the Subsidiaries or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, Exhibit E-11

appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, in the over the counter market, at any exchange, broker's board or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Pledgor, which right or equity is hereby waived or released. The Collateral Agent shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9 615 of the UCC, need the Collateral Agent account for the surplus, if any, to the Pledgor. To the extent permitted by applicable law, the Pledgor waives all claims, damages and demands it may acquire against the Collateral Agent arising out of the exercise by the Collateral Agent of any of its rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Pledgor shall remain liable for any deficiency if the proceeds of any sale or other disposition of Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any Lender to collect such deficiency. 10. Registration Rights; Private Sales. (a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Interests or the Pledged Stock, as the case may be, pursuant to paragraph 9 hereof, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended (the "Securities Act"), the Pledgor will cause the relevant Subsidiaries to (i) execute and deliver, and cause the managers, directors or officers of the relevant Subsidiaries to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Interests, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. The Pledgor agrees to cause the relevant Exhibit E-12

Subsidiaries to comply with the provisions of the securities or "Blue Sky" laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. (b) The Pledgor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Interests, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the Collateral Agent than if such sale were a public sale and agrees that such circumstances shall not, in and of themselves, result in a determination that such sale was not made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Interests or the Pledged Stock, as the case may be, for the period of time necessary to permit any of the relevant Subsidiaries to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Subsidiaries would agree to do so. (c) The Pledgor further agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make any sale or sales of all or any portion of the Interests or the Pledged Stock pursuant to this Section valid and binding and in compliance with any and all other applicable Requirements of Law. The Pledgor further agrees that a continuing breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent, the Co-Agent and the EPN Group Lenders, that the Collateral Agent, the Co-Agent and the EPN Group Lenders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against the Pledgor, and the Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred. 11. Limitation on Duties Regarding Collateral. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9 207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar securities and property for its own account. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Pledgor or otherwise. 12. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 13. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such Exhibit E-13

prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 14. Paragraph Headings. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 15. No Waiver; Cumulative Remedies; Integration. The Collateral Agent shall not by any act (except by a written instrument pursuant to this paragraph), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. This Agreement represents the agreement of the Pledgor and the Collateral Agent with respect to the subject matter hereof and there are no promises or representations by the Collateral Agent relative to the subject matter hereof not reflected herein. 16. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Pledgor and the Collateral Agent, provided that any provision of this Agreement that imposes an obligation solely on the Pledgor or provides a right in favor solely of the Collateral Agent may be waived by the Collateral Agent in a letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Agreement shall be binding upon the successors and assigns of the Pledgor and shall inure to the benefit of the Collateral Agent and its successors and assigns. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 17. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. THE PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF MAY BE BROUGHT AGAINST IT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE PLEDGOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. THE PLEDGOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF Exhibit E-14

ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE PLEDGOR AT ITS ADDRESS SET FORTH IN THE CREDIT AGREEMENT. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE COLLATERAL AGENT OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE PLEDGOR IN ANY OTHER JURISDICTION. 18. WAIVERS. (a) THE PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY ACTION DESCRIBED IN PARAGRAPH 17, OR THAT SUCH PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT, AND AGREES NOT TO PLEAD OR CLAIM THE SAME. (b) EACH OF THE PLEDGOR AND THE COLLATERAL AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OR COUNTERCLAIM OF ANY TYPE AS TO ANY MATTER ARISING DIRECTLY OR INDIRECTLY OUT OF OR WITH RESPECT TO THIS AGREEMENT. 19. Notices. All notices, requests and demands to or upon the Collateral Agent, the Pledgor or the Subsidiaries to be effective shall be in writing (including by facsimile transmission), and, unless otherwise expressly provided herein, shall be deemed to have been given or made when actually delivered or, in the case of notice by facsimile transmission, when received, addressed as set forth in the Credit Agreement, in the case of the Pledgor and the Collateral Agent, or as set forth under such party's signature below, in the case of the Subsidiaries. The Pledgor and the Subsidiaries may change their respective addresses and transmission numbers by written notice to the Collateral Agent. 20. Irrevocable Authorization and Instruction to Subsidiaries. The Pledgor hereby authorizes and instructs each of the Subsidiaries to comply with any instruction received by it from the Collateral Agent in writing that (a) states that an Event of Default has occurred and describes such Event of Default and (b) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from the Pledgor, and the Pledgor agrees that the Subsidiaries shall be fully protected in so complying. 21. Release of Liens. Upon payment and satisfaction in full of the Obligations, the Collateral Agent agrees, upon the written request of the Pledgor and at the Pledgor's sole expense, to execute, record and file such instruments and perform such acts as are necessary to release the Collateral from the Lien and security interest of this Agreement or any assignment or other security document entered into pursuant hereto. Exhibit E-15

22. The Collateral Agent Not a Member. Nothing contained in this Agreement shall be construed or interpreted (a) to transfer to the Collateral Agent any of the obligations of a member, manager, partner or other owner of any of the Subsidiaries or (b) to constitute the Collateral Agent a member, manager, partner or other owner of any of the Subsidiaries. 23. 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.

any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and the Borrower's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's and the EPN Group Lenders' Liens thereon and to effect the intent of this Security Agreement, all as fully and effectively as the Borrower might do. The Borrower hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. (b) Other Powers. The Borrower also authorizes the Collateral Agent and the EPN Group Lenders, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) No Duty on Collateral Agent or EPN Group Lenders' Part. The powers conferred on the Collateral Agent and the EPN Group Lenders hereunder are solely to protect the Collateral Agent's and the EPN Group Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent or any of the EPN Group Lenders to exercise any such powers. The Collateral Agent and the EPN Group Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to the Borrower for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. 7. Performance by Collateral Agent of Borrower's Obligations. If the Borrower fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Security Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of the Collateral Agent incurred in connection with such performance or compliance, together with interest thereon at a rate per annum 3-1/2 % above the Alternate Base Rate, shall be payable by the Borrower to the Collateral Agent on demand and shall constitute Obligations secured hereby. 8. Proceeds. In addition to the rights of the Collateral Agent and the EPN Group Lenders specified in Section 3(d) with respect to payments of Accounts, it is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by the Borrower consisting of cash, checks and other near-cash items shall be held by the Borrower in trust for the Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders, segregated from other funds of the Borrower, and shall, forthwith upon receipt by the Borrower, be turned over to the Collateral Agent in the exact form received by the Borrower (duly indorsed by the Borrower to the Collateral Exhibit F-17

Agent, if required), and (b) any and all such Proceeds received by the Collateral Agent (whether from the Borrower or otherwise) may, in the sole discretion of the Collateral Agent, be held by the Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders as collateral security for, and/or then or at any time thereafter may be applied by the Collateral Agent against, the Obligations (whether matured or unmatured), such application to be in such order as the Collateral Agent shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full and the Commitments shall have been terminated shall be paid over to the Borrower or to whomsoever may be lawfully entitled to receive the same. 9. Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the EPN Group Lenders and the Marco Polo Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Borrower or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any of the EPN Group Lenders or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any of the EPN Group Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Borrower, which right or equity is hereby waived or released. The Borrower further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at the Borrower's premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the EPN Group Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to the Borrower. To the extent permitted by applicable law, the Borrower waives all claims, damages and demands it may acquire against the Collateral Agent or any of the EPN Group Lenders arising out of the exercise by them of any rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of Exhibit F-18

a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Borrower shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the EPN Group Lenders to collect such deficiency. 10. Limitation on Duties Regarding Preservation of Collateral. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, any of the EPN Group Lenders, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Borrower or otherwise. 11. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 12. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 13. Paragraph Headings. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 14. No Waiver; Cumulative Remedies. Neither the Collateral Agent nor any of the EPN Group Lenders shall by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any of the EPN Group Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any of the EPN Group Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent or such EPN Group Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. Exhibit F-19

15. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Borrower and the Collateral Agent, provided that any provision of this Security Agreement may be waived by the Collateral Agent in a written letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Security Agreement shall be binding upon the successors and assigns of the Borrower and shall inure to the benefit of the Collateral Agent and the EPN Group Lenders and their respective successors and assigns. This Security Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. 16. Notices. Notices hereunder may be given by mail or by facsimile transmission, addressed or transmitted to the Person to which it is being given at such Person's address or transmission number set forth in the Credit Agreement and shall be effective (a) in the case of mail, 3 days after deposit in the postal system, first class postage pre-paid and (b) in the case of facsimile notices, when sent. The Borrower may change its address and transmission number by written notice to the Collateral Agent, and the Collateral Agent or any of the EPN Group Lenders may change its address and transmission number by written notice to the Borrower and, in the case of a any of the EPN Group Lenders, to the Collateral Agent. 17. Authority of Collateral Agent. The Borrower acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as among the Collateral Agent, the EPN Group Lenders and the Marco Polo Lenders be governed by the Credit Agreement, the Marco Polo Financing Documents, and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Borrower, the Collateral Agent shall be conclusively presumed to be acting as agent for the EPN Group Lenders, and the Marco Polo Lenders with full and valid authority so to act or refrain from acting, and the Borrower shall not be under any obligation, or entitlement, to make any inquiry respecting such authority.

Amendments, etc. with respect to the Obligations; Waiver of Rights. Each Guarantor shall remain obligated hereunder and under the other Loan Documents to which it is a party notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Obligations or any guarantees thereof made by the EPN Group Administrative Agents or any of the EPN Group Lenders may be rescinded by such Person and any of the Obligations or any guarantees thereof continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the EPN Group Administrative Agents or any of the EPN Group Lenders and the EPN Credit Agreement, the EPNHC Credit Agreement, the Notes, the other Loan Documents, any other collateral security document or other guarantee or document in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the EPN Group Administrative Agents and/or any of the EPN Group Lenders may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the EPN Group Administrative Agents or any of the EPN Group Lenders for the payment of the Obligations may be sold, exchanged, waived, surrendered or released.

Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the EPN Group Borrowers or any of the Guarantors with respect to the Obligations or any guarantee thereof. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, regularity or enforceability of the EPN Credit Agreement, the EPNHC Credit Agreement, the Notes, any of the other Loan Documents, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the EPN Group Administrative Agents or any of the EPN Group Lenders, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the EPN Group Borrowers against the EPN Group Administrative Agents or any of the EPN Group Lenders, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the EPN Group Borrowers or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the EPN Group Borrowers for the Obligations, or of such Guarantor under this Guarantee or any other Loan Document, in bankruptcy or in any other instance.

Reinstatement. This Guarantee shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is Exhibit G-7

rescinded or must otherwise be restored or returned by the EPN Group Administrative Agents or any of the EPN Group Lenders upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any of the EPN Group Borrowers or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, any of the EPN Group Borrowers or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made. 9.

(g) such Guarantor has filed or caused to be filed all tax returns required to be filed by it and has paid all taxes due on said returns or on any assessments made against it (other than those being contested in good faith by appropriate proceedings for which adequate reserves have been provided on its books); and (h) On the date of execution of this Guarantee and upon each Borrowing Date (i) the amount of the "present fair saleable value" of the assets of each Guarantor will, as of each such date, exceed the amount of all "liabilities of such Guarantor, contingent or otherwise", as of such date, as such quoted terms are determined in accordance with applicable federal and state laws governing determinations of the insolvency of debtors, (ii) the present fair saleable value of the assets of each Guarantor will, as of such date, be greater than the amount that will be required to pay the liability of such Guarantor on its debts as such debts become absolute and matured, (iii) each Guarantor will not have, as of such date, an unreasonably small amount of capital with which to conduct its business, and (iv) each Guarantor will be able to pay its debts as they mature. For purposes of this subsection 10(i) "debt" means "liability on a claim", and "claim" means any (x) right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured; or (y) right to an equitable remedy for payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured or unmatured, disputed, undisputed, secured or unsecured. Each of the Guarantors shall be deemed to make the representation contained in this subsection 10(h) on each Borrowing Date. Each Guarantor agrees that the foregoing representations and warranties shall be deemed to have been made by such Guarantor on the date of each borrowing by any of the EPN Group Borrowers under the EPN Credit Agreement or the EPNHC Credit Agreement on and as of such date of borrowing as though made hereunder on and as of such date. 11. Severability.

No failure to exercise, nor any delay in exercising, on the part of the EPN Group Administrative Agents or any of the EPN Group Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the EPN Group Administrative Agents or any of the EPN Group Lenders of any right or remedy Exhibit G-9

Integration; Waivers and Amendments; Successors and Assigns; Governing Law.

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

the reorganization thereof, the property so distributed shall be delivered to the Collateral Agent to be held by it, subject to the terms hereof, as additional collateral security for the Obligations. If any sums of money or property so paid or distributed in respect of the Collateral shall be received by any Pledgor, such Pledgor shall, until such money or property is paid or delivered to the Collateral Agent, hold such money or property in trust for the Collateral Agent, segregated from other funds of such Pledgor, as additional collateral security for the Obligations.

The Pledgors will defend the right, title and interest of the Collateral Agent in and to the Collateral against the claims and demands of all Persons whomsoever. The Pledgors will not sell, transfer or otherwise dispose of any of the Collateral, or attempt, offer or contract to do so. (c) At any time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of the Pledgors, the Pledgors will promptly and duly execute and deliver such further instruments and documents and take such further actions as the Collateral Agent may reasonably request for the purposes of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Lien granted hereby. Each Pledgor hereby authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file financing statements and amendments to financing statements that describe the Collateral, in such jurisdictions as the Collateral Agent may deem necessary or desirable in order to perfect or maintain the perfection of the security interests granted by each Pledgor under this Agreement. Each Pledgor hereby further authorizes the Collateral Agent, its counsel or its representative, at any time and from time to time, to file continuation statements with respect to previously filed financing statements. If any amount payable under or in connection with any of the Collateral shall be or become evidenced by any promissory note or other instrument, such note or instrument shall be immediately pledged hereunder to the Collateral Agent, duly endorsed in a manner satisfactory to the Collateral Agent.

(f) Promptly, but in no case later than 30 days after any Pledgor forms or acquires a Subsidiary that is to be a Restricted Subsidiary, such Pledgor shall provide to the Collateral Agent a supplement to this Agreement in the form of Exhibit A hereto, which shall include a schedule supplementing Schedule I, Schedule II, or Schedule III, as the case may be, to pledge its ownership interests in such Restricted Subsidiary to the Collateral Agent. 6. Cash Distributions; Cash Dividends; Voting Rights. Unless an Event of Default shall have occurred and be continuing, each Pledgor shall be permitted to receive (a) all cash distributions paid in the normal course of business of the LLCs and to exercise all voting, member and manager rights with respect to the Interests, and (b) all cash dividends paid in the normal course of business of any corporate or other Subsidiary and consistent with past practice, in respect of the Pledged Stock and to exercise all voting and corporate rights with respect to the Pledged Stock; provided, however, that no vote shall be cast or right exercised or other action taken which, in the Collateral Agent's reasonable judgment, would impair the Collateral or which would be inconsistent with or result in a breach of any provision of the EPN Credit Agreement or the EPNHC Credit Agreement, the Notes, any other Loan Document or this Agreement. 7. Rights of the Collateral Agent. (a) If an Event of Default shall occur and be continuing, (i) the Collateral Agent shall have the right to receive and shall receive any and all cash distributions or dividends paid in respect of the Collateral and make application thereof to the Obligations in such order as it may determine, and (ii) to the extent permitted by applicable law, all shares or certificates of or evidencing the Interests and the Pledged Stock shall be registered in the name of the Collateral Agent or its nominee, and (whether or not so registered) the Collateral Agent or its nominee may thereafter exercise (A) all voting, corporate, member, manager and other rights pertaining to the Interests or the shares of the Pledged Stock, as the case may be, and (B) any and all rights of conversion, exchange, subscription and any other rights, privileges or options pertaining to the Interests or such shares of the Pledged Stock, as the case may be, as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Interests or the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the structure of any of the Subsidiaries, or upon the exercise by any Pledgor or the Collateral Agent of any right, privilege or option pertaining to such shares or certificates of or evidencing the Interests or the Pledged Stock, and in connection therewith, the right to deposit and deliver any and all of the Interests or the Pledged Stock with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. Exhibit H-10

(b) The rights of the Collateral Agent hereunder shall not be conditioned or contingent upon the pursuit by the Collateral Agent of any right or remedy against any Subsidiary, or against any other Person which may be or become liable in respect of all or any part of the Obligations or against any other collateral security therefor, guarantee thereof or right of offset with respect thereto. The Collateral Agent shall not be liable for any failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so, nor shall it be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Pledgor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. 8. Collateral Agent's Appointment as Attorney-in-Fact. (a) Each Pledgor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Pledgor and in the name of such Pledgor or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the Collateral Agent the power and right, on behalf of such Pledgor without notice to or assent by such Pledgor to do the following: (i) upon the occurrence and continuation of an Event of Default to ask, demand, collect, receive and give acceptances and receipts for any and all moneys due and to become due with respect to the Collateral and, in the name of such Pledgor or its own name or otherwise, to take possession of, endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to the Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise as deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due with respect to the Collateral or whenever payable; (ii) to pay or discharge taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral; and (iii) upon the occurrence and during the continuance of an Event of Default, (A) to direct any Person liable for any payment to any Pledgor with respect to the Collateral to make payment of any and all moneys due and to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to receive payment of and receipt for any and all moneys, claims and other amounts due and to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, drafts against debtors, assignments, verifications and notices in connection with accounts and other documents relating to the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral and to enforce any other right in respect of any Collateral; Exhibit H-11

(E) to defend any suit, action or proceeding brought against any Pledgor with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; and (G) generally, to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and a Pledgors' expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as the Pledgors might do. Each Pledgor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. (b) The powers conferred on the Collateral Agent hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to Pledgors, any Subsidiary or to any other member or partner of or owner of any limited or general partner interest, limited liability company interest or other equity interest in any Non-Corporate Subsidiary for any act or failure to act. (c) Each Pledgor also authorizes the Collateral Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 of this Agreement, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. 9. Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing and to the extent permitted by applicable law, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Pledgor, any of the Subsidiaries or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, in the over the counter market, at any exchange, broker's board or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any Exhibit H-12

right or equity of redemption in any Pledgor, which right or equity is hereby waived or released. The Collateral Agent shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9 615 of the UCC, need the Collateral Agent account for the surplus, if any, to any Pledgor. To the extent permitted by applicable law, each Pledgor waives all claims, damages and demands it may acquire against the Collateral Agent arising out of the exercise by the Collateral Agent of any of its rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Pledgors shall remain liable for any deficiency if the proceeds of any sale or other disposition of Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the EPN Group Lenders to collect such deficiency. 10. Registration Rights; Private Sales. (a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Interests or the Pledged Stock, as the case may be, pursuant to paragraph 9 hereof, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended (the "Securities Act"), each Pledgor will cause the relevant Subsidiaries to (i) execute and deliver, and cause the managers, directors or officers of the relevant Subsidiaries to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Interests or the Pledged Stock, as the case may be, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Interests, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Pledgor agrees to cause the relevant Subsidiaries to comply with the provisions of the securities or "Blue Sky" laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. (b) Each Pledgor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Interests, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to Exhibit H-13

resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the Collateral Agent than if such sale were a public sale and agrees that such circumstances shall not, in and of themselves, result in a determination that such sale was not made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Interests or the Pledged Stock, as the case may be, for the period of time necessary to permit any of the relevant Subsidiaries to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Subsidiaries would agree to do so. (c) Each Pledgor further agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make any sale or sales of all or any portion of the Interests or the Pledged Stock pursuant to this Section valid and binding and in compliance with any and all other applicable Requirements of Law. Each Pledgor further agrees that a continuing breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent, the Co-Agent and the EPN Group Lenders, that the Collateral Agent, the Co-Agent and the EPN Group Lenders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against any Pledgor, and each Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred. 11. Limitation on Duties Regarding Collateral. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9 207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar securities and property for its own account. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Pledgor or otherwise. 12. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 13. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 14. Paragraph Headings. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. Exhibit H-14

15. No Waiver; Cumulative Remedies; Integration. The Collateral Agent shall not by any act (except by a written instrument pursuant to this paragraph), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. This Agreement represents the agreement of the Pledgors and the Collateral Agent with respect to the subject matter hereof and there are no promises or representations by the Collateral Agent relative to the subject matter hereof not reflected herein. 16. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Pledgors and the Collateral Agent, provided that any provision of this Agreement that imposes an obligation solely on a Pledgor or provides a right in favor solely of the Collateral Agent may be waived by the Collateral Agent in a letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Agreement shall be binding upon the successors and assigns of the Pledgors and shall inure to the benefit of the Collateral Agent and its successors and assigns.

(i) Each Grantor (either itself or through licensees) will, except with respect to any Trademark that such Grantor shall reasonably determine is of negligible economic value to it, (i) continue to use each Trademark on each and every trademark class of goods applicable to its current line as reflected in its current catalogs, brochures and price lists in order to maintain such Trademark in full force free from any claim of abandonment for non-use, (ii) maintain as in the past the quality of products and services offered under such Trademark, (iii) employ such Trademark with the appropriate notice of registration, (iv) not adopt or use any mark which is confusingly similar or a colorable imitation of such Trademark unless the Collateral Agent, for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders, shall obtain a perfected security interest in such mark pursuant to this Security Agreement, and (v) not (and not permit any licensee or sublicensee thereof to) do any act or knowingly omit to do any act whereby any Trademark may become invalidated. (ii) Each Grantor will not, except with respect to any Patent that such Grantor shall reasonably determine is of negligible economic value to it, do any act, or omit to do any act, whereby any Patent may become abandoned or dedicated. (iii) Each Grantor will notify the Collateral Agent and the EPN Group Lenders immediately if it knows, or has reason to know, that any application or registration relating to any Patent or Trademark may become abandoned or dedicated, or of any adverse determination or development (including, without limitation, the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office or any court or tribunal in any country) regarding such Grantor's ownership of any Patent or Trademark or its right to register the same or to keep and maintain the same. Exhibit I-13

(iv) Whenever a Grantor, either by itself or through any agent, employee, licensee or designee, shall file an application for the registration of any Patent or Trademark with the United States Patent and Trademark Office or any similar office or agency in any other country or any political subdivision thereof, such Grantor shall report such filing to the Collateral Agent and the EPN Group Lenders within five Business Days after the last day of the fiscal quarter in which such filing occurs. Upon request of the Collateral Agent, such Grantor shall execute and deliver any and all agreements, instruments, documents, and papers as the Collateral Agent may request to evidence the Collateral Agent's and the EPN Group Lenders' security interest in any Patent or Trademark and the goodwill and general intangibles of such Grantor relating thereto or represented thereby, and such Grantor hereby constitutes the Collateral Agent its attorney-in-fact to execute and file all such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power being coupled with an interest is irrevocable until the Obligations are paid in full and the Commitments are terminated. (v) Each Grantor will take all reasonable and necessary steps, including, without limitation, in any proceeding before the United States Patent and Trademark Office, or any similar office or agency in any other country or any political subdivision thereof, to maintain and pursue each application (and to obtain the relevant registration) and to maintain each registration of the Patents and Trademarks, including, without limitation, filing of applications for renewal, affidavits of use and affidavits of incontestability. (vi) In the event that any Patent or Trademark included in the Collateral is infringed, misappropriated or diluted by a third party, each Grantor shall promptly notify the Collateral Agent and the EPN Group Lenders after it learns thereof and shall, unless such Grantor shall reasonably determine that such Patent or Trademark is of negligible economic value to such Grantor which determination such Grantor shall promptly report to the Collateral Agent and the EPN Group Lenders, promptly sue for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all damages for such infringement, misappropriation or dilution, or take such other actions as such Grantor shall reasonably deem appropriate under the circumstances to protect such Patent or Trademark. (q) Vehicles. Each Grantor will maintain each Vehicle in good operating condition, ordinary wear and tear and immaterial impairments of value and damage by the elements excepted, and will provide all maintenance, service and repairs necessary for such purpose. No Vehicle shall be removed from the state which has issued the certificate of title or ownership therefor for a period in excess of 60 days. (r) Commercial Tort Claims.

by such Grantor containing a brief description thereof, and granting to the Collateral Agent in such writing (for the benefit of the EPN Group Lenders and the Marco Polo Lenders) a security interest therein and in the Proceeds thereof, all upon the terms of this Security Agreement, with such writing to be in form and substance satisfactory to the Collateral Agent and the EPN Group Lenders. The provisions of the preceding sentence shall apply only to a Commercial Tort Claim that satisfies the following requirements: (i) the monetary value claimed by or payable to the relevant Grantor in connection with such Commercial Tort Claim shall exceed $5,000,000, and either (ii) (A) such Grantor shall have filed a law suit or counterclaim or otherwise commenced legal proceedings (including, without limitation, arbitration proceedings) against the Person against whom such Commercial Tort Claim is made, or (B) such Grantor and the Person against whom such Commercial Tort Claim is asserted shall have entered into a settlement agreement with respect to such Commercial Tort Claim. In addition, to the extent that the existence of any Commercial Tort Claim held or acquired by any Grantor is disclosed by EPN or any Grantor in any public filing with the Securities Exchange Commission or any successor thereto or analogous Governmental Authority, or to the extent that the existence of any such Commercial Tort Claim is disclosed in any press release issued by EPN or any Grantor, then, upon the request of the Collateral Agent, the relevant Grantor shall, within thirty (30) days after such request is made, transmit to the Collateral Agent and the EPN Group Lenders a writing signed by such Grantor containing a brief description of such Commercial Tort Claim and granting to the Collateral Agent in such writing (for the benefit of the EPN Group Lenders and the Marco Polo Lenders) a security interest therein and in the Proceeds thereof, all upon the terms of this Security Agreement, with such writing to be in form and substance satisfactory to the Collateral Agent and the EPN Group Lenders. 6. Collateral Agent's Appointment as Attorney-in-Fact. (a) Powers. Each Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, from time to time in the Collateral Agent's discretion, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do the following: (i) in the case of any Account, Chattel Paper or Payment Intangible, at any time when the authority of such Grantor to collect the Accounts, Chattel Paper or Payment Intangible has been curtailed or terminated pursuant to the first sentence of Section 3(d) hereof, or in the case of any other Collateral, at any time when any Event of Default shall have occurred and is continuing, in the name of such Grantor or its own name, or otherwise, to take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Account, Instrument, General Intangible, Chattel Paper, Exhibit I-15

or Payment Intangible, or with respect to any other Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any Account, Instrument, or General Intangible or with respect to any other Collateral whenever payable; (ii) to pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Security Agreement and to pay all or any part of the premiums therefor and the costs thereof; and (iii) upon the occurrence and during the continuance of any Event of Default, (A) to direct any Person liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (B) to ask or demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against such Grantor, assignments, verifications, notices and other documents in connection with any of the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any thereof and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against any Grantor with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described in clause (E) above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate; (G) to assign any Patent or Trademark (along with the goodwill of the business to which any such Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its sole discretion determine; and (H) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and to do, at the Collateral Agent's option and each Grantor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's and the EPN Group Lenders' Liens thereon and to effect the intent of this Security Agreement, all as fully and effectively as any Grantor might do. Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. (b) Other Powers. Each Grantor also authorizes the Collateral Agent and the EPN Group Lenders, at any time and from time to time, to execute, in connection with Exhibit I-16

the sale provided for in Section 9 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) No Duty on Collateral Agent or EPN Group Lenders' Part. The powers conferred on the Collateral Agent and the EPN Group Lenders hereunder are solely to protect the Collateral Agent's and the EPN Group Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent or any of the EPN Group Lenders to exercise any such powers. The Collateral Agent and the EPN Group Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. 7. Performance by Collateral Agent of the Grantor's Obligations. If any Grantor fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Security Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of the Collateral Agent incurred in connection with such performance or compliance, together with interest thereon at a rate per annum 3-1/2 % above the Alternate Base Rate, shall be payable by such Grantor to the Collateral Agent on demand and shall constitute Obligations secured hereby. 8. Proceeds. In addition to the rights of the Collateral Agent and the EPN Group Lenders specified in Section 3(d) with respect to payments of Accounts, it is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by each Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly indorsed by such Grantor to the Collateral Agent, if required), and (b) any and all such Proceeds received by the Collateral Agent (whether a Grantor or otherwise) may, in the sole discretion of the Collateral Agent, be held by the Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco Polo Lenders as collateral security for, and/or then or at any time thereafter may be applied by the Collateral Agent against, the Obligations (whether matured or unmatured), such application to be in such order as the Collateral Agent shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full and the Commitments shall have been terminated shall be paid over to such Grantor or to whomsoever may be lawfully entitled to receive the same. 9. Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the EPN Group Lenders and the Marco Polo Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, Exhibit I-17

appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any of the EPN Group Lenders or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any of the EPN Group Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived or released. Each Grantor further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor's premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the EPN Group Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to such Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any of the EPN Group Lenders arising out of the exercise by them of any rights hereunder except to the extent any thereof arise solely from the willful misconduct of the Collateral Agent. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent or any of the EPN Group Lenders to collect such deficiency. 10. Limitation on Duties Regarding Preservation of Collateral. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, any of the EPN Group Lenders, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or otherwise. 11. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest. 12. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any Exhibit I-18

such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 13. Paragraph Headings. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 14. No Waiver; Cumulative Remedies. Neither the Collateral Agent nor any of the EPN Group Lenders shall by any act (except by a written instrument pursuant to Section 15 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any of the EPN Group Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any of the EPN Group Lenders of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent or any such EPN Group Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 15. Waivers and Amendments; Successors and Assigns; Governing Law. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Grantors and the Collateral Agent, provided that any provision of this Security Agreement may be waived by the Collateral Agent in a written letter or agreement executed by the Collateral Agent or by facsimile transmission from the Collateral Agent. This Security Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Collateral Agent and the EPN Group Lenders and their respective successors and assigns. This Security Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. 16. Notices. Notices hereunder may be given by mail or by facsimile transmission, addressed or transmitted to the Person to which it is being given at such Person's address or transmission number set forth in the EPN Credit Agreement and the EPNHC Credit Agreement and shall be effective (a) in the case of mail, 3 days after deposit in the postal system, first class postage pre-paid and (b) in the case of facsimile notices, when sent. Each Grantor may change its address and transmission number by written notice to the Collateral Agent, and the Collateral Agent or any of the EPN Group Lenders may change its address and transmission number by written notice to each Grantor and, in the case of any of the EPN Group Lenders, to the Collateral Agent. 17. Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as among the Collateral Agent, the EPN Group Exhibit I-19

Lenders and the Marco Polo Lenders be governed by EPN Credit Agreement, the EPNHC Credit Agreement, the Marco Polo Financing Documents and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and each Grantor, the Collateral Agent shall be conclusively presumed to be acting as agent for the EPN Group Lenders and the Marco Polo Lenders with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority. 18. CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH GRANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF MAY BE BROUGHT AGAINST IT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT AND SUCH OTHER LOAN DOCUMENTS, EACH GRANTOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH GRANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO SUCH GRANTOR AT ITS ADDRESS SET FORTH UNDER ITS SIGNATURE BELOW. NOTHING HEREIN AND IN SUCH OTHER LOAN DOCUMENTS SHALL AFFECT THE RIGHT OF THE COLLATERAL AGENT OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR OT COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST EACH GRANTOR IN ANY OTHER JURISDICTION. 19. WAIVERS. (a) EACH GRANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY ACTION DESCRIBED IN PARAGRAPH 18, OR THAT SUCH PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT, AND AGREES NOT TO PLEAD OR CLAIM THE SAME. (b) EACH GRANTOR AND THE COLLATERAL AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OR COUNTERCLAIM OF ANY TYPE AS TO ANY MATTER ARISING DIRECTLY OR INDIRECTLY OUT OF OR WITH RESPECT TO THIS AGREEMENT. IN WITNESS WHEREOF, each Grantor has caused this Security Agreement to be duly executed and delivered as of the date first above written.

(a) The EPN Group Administrative Agents, the EPN Group Lenders, and the Issuing Banks hereby acknowledge and agree to the appointment of JPMorgan as "Collateral Agent" pursuant to Section 12.1 of each of the EPN Group Credit Agreements to act on behalf of the EPN Group Lenders. If at any time JPMorgan resigns or is replaced as the Collateral Agent, then the Required EPN Group Lenders shall select a replacement "collateral agent" hereunder in accordance with the procedures provided in the EPN Group Credit Agreements for replacement of the "Collateral Agent", subject to the approval of EPN or EPNHC as set forth therein. (b) Notwithstanding anything to the contrary provided in the EPN Group Credit Agreements: (i) If the EPN Lenders under the EPN Credit Agreement, the EPNHC Lenders under the EPNHC Credit Agreement, or the Senior Secured Acquisition Term Loan Lenders under the Senior Secured Acquisition Term Loan Credit Agreement have the right to Accelerate or exercise any other remedies, then the EPN Group Lenders under the other EPN Group Credit Agreements shall have the same right. (ii) If any decision, determination, instruction, action, consent, waiver or amendment is made by the "Required Lenders" (as defined in each EPN Group Credit Agreement) with respect to any of the EPN Group Credit Agreements (the "Initial Vote Credit Agreement") and if a corresponding or substantially similar decision, determination, instruction, action, consent, waiver or amendment is voted on by the EPN Group Lenders under either or both of the other EPN Group Credit Agreements (each, the "Additional Vote Credit Agreement"), then each EPN Group Lender that is a Lender under both the Initial Vote Credit Agreement Exhibit K-8

and any Additional Vote Credit Agreement agrees to vote consistently as an EPN Group Lender under the Initial Vote Credit Agreement, each such Additional Vote Credit Agreement and hereunder. By way of example, if any EPN Group Lender votes to Accelerate the EPN Loans under the EPN Credit Agreement, such EPN Group Lender agrees to vote to Accelerate the EPNHC Loans hereunder and under the EPNHC Credit Agreement if it is a party to such vote, and agrees to vote to Accelerate the Senior Secured Acquisition Term Loans hereunder and under the Senior Secured Acquisition Term Loan Credit Agreement if it is a party to such vote. (c) When a vote of the EPN Group Lenders is required pursuant to this Agreement or any EPN Group Credit Agreement, the EPN Administrative Agent shall ascertain the votes of the EPN Lenders, the EPNHC Administrative Agent shall ascertain the votes of the EPNHC Lenders and the Senior Secured Acquisition Term Loan Administrative Agent shall ascertain the votes of the Senior Secured Acquisition Term Loan Lenders. Each of the EPN Group Administrative Agents agrees with the other EPN Group Administrative Agents that it will promptly provide such information regarding such votes to the other EPN Group Administrative Agents. The EPN Group Administrative Agents shall then compile the votes of the EPN Lenders, the EPNHC Lenders and the Senior Secured Acquisition Term Loan Lenders to determine whether the vote of the EPN Group Lenders constitutes the Required EPN Group Lenders. (d) Notwithstanding any other provision of this Agreement, to the extent not inconsistent with the terms and provisions of the EPN Group Credit Agreements and EPN Group Security Documents, any EPN Group Administrative Agent or any EPN Group Lender may, without instruction from its EPN Group Administrative Agent or the EPN Group Lenders under the other EPN Group Credit Agreements (but in no event shall be required to), take action permitted by applicable law to preserve its rights and security including but not limited to curing any default or alleged default under any contract entered into by EPN or EPNHC, as applicable, paying any tax, fee, or expense on behalf of EPN or EPNHC, as applicable, and paying insurance premiums on behalf of EPN or EPNHC, as applicable and each EPN Group Lender taking any such action shall notify each of the EPN Group Administrative Agents and the Collateral Agent of the action so taken. (e) Each EPN Group Administrative Agent agrees with the other EPN Group Administrative Agents and the Collateral Agent that: (i) to the extent available, it will from time to time promptly provide such information to the other EPN Group Administrative Agents and the Collateral Agent as may be reasonably necessary to enable the other EPN Group Administrative Agents or the Collateral Agent to make any calculation referred to in or necessary to implement this Section 3 or otherwise reasonably required by the other EPN Group Administrative Agents and the Collateral Agent for any other purpose hereof; and (ii) to the extent reasonably possible, it will from time to time consult with the other EPN Group Administrative Agents and the Collateral Agent in Exhibit K-9

good faith regarding the enforcement of its and each EPN Group Lender's rights and remedies under its EPN Group Credit Agreement with a view to recovering amounts due under the EPN Group Credit Agreements in an effective and cost-efficient manner. 4. RIGHTS IN COLLATERAL. (a) Notwithstanding anything to the contrary contained in any EPN Loan Document, any EPNHC Loan Document, any Senior Secured Acquisition Term Loan Document or any Marco Polo Loan Document and irrespective of the time, order or method of attachment or perfection of the security interests created by the EPN Loan Documents, the EPNHC Loan Documents or the Marco Polo Loan Documents, anything contained in any filing or agreement to which the EPN Administrative Agent, the EPNHC Administrative Agent, the Senior Secured Acquisition Term Loan Administrative Agent, the Marco Polo Administrative Agent, the Collateral Agent, any EPN Lender, any EPNHC Lender, any Senior Secured Acquisition Term Loan Lender or any Marco Polo Lender now or hereafter may be a party and the rules for determining priority under the Uniform Commercial Code or any other law governing the relative priorities of secured creditors, any security interest in the Collateral secures the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations and the Clawback Obligation on a pari passu basis. (b) So long as the EPN Loan Obligations have not been paid in full and the commitments under the EPN Credit Agreement have not been terminated, the EPNHC Loan Obligations have not been paid in full and the Senior Secured Acquisition Term Loan Obligations have not been paid in full, whether or not any bankruptcy proceeding or similar event or proceeding has been commenced by or against EPN, EPNHC, or any other EPN Group Loan Party, (i) the Marco Polo Administrative Agent and the Marco Polo Lenders will not (A) exercise or seek to exercise any rights or exercise any remedies with respect to any Collateral, (B) institute any action or proceeding with respect to such rights or remedies, including without limitation, any action of foreclosure, (C) contest, protest or object to any foreclosure proceeding or action brought by the Collateral Agent or any other exercise by the Collateral Agent of any rights and remedies relating to the Collateral under any EPN Group Security Documents or (D) object to the forbearance by the Collateral Agent from bringing or pursuing any foreclosure proceeding or action or any other exercise of any rights or remedies relating to the Collateral, and (ii) the Collateral Agent shall have the exclusive right to enforce rights and exercise remedies with respect to the Collateral. (c) In exercising rights and remedies with respect to the Collateral on behalf of the Lenders, the Collateral Agent may enforce the provisions of the EPN Group Security Documents and exercise remedies thereunder, all in such order and in such manner as the Collateral Agent may determine in the exercise of its sole business judgment in accordance with the provisions of this Section 4. Such exercise and enforcement shall include, without limitation, the rights to sell or otherwise dispose of Collateral, to incur expenses in connection with such sale or disposition, to exercise rights and powers as a holder of the shares of stock, limited liability company or partnership interests, other equity interests and other property included in the Collateral under the EPN Group Security Documents or otherwise and to exercise all the rights and remedies of a secured lender under the Uniform Commercial Code of any applicable jurisdiction. Exhibit K-10

(d) Any money, property or securities realized upon the sale, disposition or other realization by the Collateral Agent upon all or any part of the Collateral and any money, property or securities received by the Collateral Agent from any other Person in respect of the Collateral, shall be applied by the Collateral Agent in the following order: (i) First, to the payment in full of all costs and expenses (including, without limitation, attorneys' fees and disbursements) paid or incurred by the Collateral Agent in connection with such realization on the Collateral or the protection of the Lenders' rights and interests therein; (ii) Second, to the payment (or collateralization of payment, if such obligations are not yet matured or are evidenced by unexpired, undrawn letters of credit) in full of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations and the Clawback Obligation on a pro rata basis based on the respective aggregate amounts thereof; and (iii) Third, to pay to the EPN Group Loan Parties or their respective representatives or as a court of competent jurisdiction may direct, any surplus then remaining. (e) The Collateral Agent's rights with respect to the Collateral include the right to release any or all of the Collateral from the Lien granted or created under the EPN Group Security Documents in connection with the sale of such Collateral, notwithstanding that the net proceeds of any such sale may not be used to permanently prepay any EPN Loan Obligations, EPNHC Loan Obligation, Senior Secured Acquisition Term Loan Obligation or Clawback Obligation. In addition, the Collateral Agent and the Required EPN Group Lenders may release Collateral and may fail to perfect any security interest in any Collateral and may agree to any exchange of Collateral for property not constituting Collateral, all without liability to the Marco Polo Lenders. Upon any sale by the Collateral Agent of Collateral, the Lien and security interest created pursuant to the EPN Group Security Documents in such Collateral shall be automatically released. The Marco Polo Administrative Agent, for itself and on behalf of the Marco Polo Lenders, hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent of the Collateral Agent, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Marco Polo Lenders and in the name of the Marco Polo Lenders or in the Collateral Agent's own name, from time to time in the Collateral Agent's discretion or as directed by the Required EPN Group Lenders, for the purpose of carrying out the terms of this paragraph, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this paragraph, including, without limitation, any financing statements, endorsements, assignments or other instruments of transfer or release. The Marco Polo Administrative Agent and the Marco Polo Lenders hereby ratify all that said attorneys shall lawfully do or cause to be done pursuant to the power of attorney granted in this paragraph. (f) In the event that all of the EPN Loan Obligations have been paid in full and the commitments under the EPN Credit Agreement have been terminated, the EPNHC Loan Obligations have been paid in full and the Senior Secured Acquisition Term Loan Obligations have been paid in full, and at such time the Clawback Obligation is still outstanding, (i) the Exhibit K-11

Marco Polo Administrative Agent shall have the right to direct the Collateral Agent to enforce the provisions of the EPN Group Security Documents and exercise remedies thereunder; (ii) if at such time the Collateral has been sold or otherwise disposed of and the Collateral Agent, on the one hand, or Marco Polo Administrative Agent or any Marco Polo Lender, on the other, holds cash proceeds remaining after application as set forth in clauses (d)(i) and (ii) above, the Persons holding such cash proceeds shall turn over such remaining proceeds to the Marco Polo Administrative Agent, to satisfy any remaining Clawback Obligation, and then any such remaining proceeds shall be turned over to the EPN Group Loan Parties for application as set forth in clause (d)(iii) above; and (iii) the Collateral Agent shall continue to act as collateral agent for the Marco Polo Lenders, provided, that the Collateral Agent may elect in lieu thereof to assign and transfer its rights as collateral agent for the benefit of the Marco Polo Lenders to the Marco Polo Administrative Agent. (g) The arrangements contemplated by this Agreement shall apply notwithstanding any Event of Default (as defined in each of the EPN Group Credit Agreements) or any Acceleration under an EPN Group Credit Agreement or demand under any of the EPN Group Guarantees; the date of execution, delivery, attachment, perfection or registration of any EPN Group Security Document (or lack of any thereof), the exercise of any right of setoff; the priority of any EPN Group Security Document; the date of advance of any funds; the date of creation, perfection or determination of any charges or security interests; the date of appointment of any receiver or receiver-manager or bankruptcy trustee or of taking any other enforcement proceedings; the date of obtaining any judgment; the date of notification in respect of any account receivable; any provision of applicable law or requirement of any Governmental Authority; any defense, claim or any right not provided under this Agreement; or the terms of any agreement between any Lender or EPN Group Loan Party under any other document or instrument between or among such parties, whether or not a bankruptcy, receivership or insolvency proceedings shall at any time have been commenced. (h) The Collateral Agent shall make all payments and distributions under this Section 4: (i) on account of the EPN Loan Obligations to the EPN Administrative Agent for distribution in accordance with the terms and provisions of the EPN Credit Agreement; (ii) on account of the EPNHC Loan Obligations to the EPNHC Administrative Agent for distribution in accordance with the terms and provisions of the EPNHC Credit Agreement; (iii) on account of the Senior Secured Acquisition Term Loan Obligations to the Senior Secured Acquisition Term Loan Administrative Agent for distribution in accordance with the terms and provisions of the Senior Secured Acquisition Term Loan Credit Agreement; and (iv) on account of the Clawback Obligation to the Marco Polo Administrative Agent for distribution in accordance with the terms and provisions of the EPN Sponsor Agreement and the Marco Polo Credit Agreement. (i) Each of the Lenders and the Agents acknowledges and agrees that it shall only have recourse to the Collateral through the Collateral Agent and that it shall have no independent recourse to the Collateral. (j) If any Lender or Agent acquires custody, control or possession of any Collateral or any proceeds thereof, other than pursuant to the terms of this Agreement, such Lender or Agent shall promptly cause such Collateral or proceeds to be delivered to or put in the custody, possession or control of the Collateral Agent or, if the Collateral Agent shall so Exhibit K-12

designate, an agent of the Collateral Agent (which agent may be an Affiliate of the Collateral Agent or any Lender) in the same form of payment or property received, with appropriate endorsements, for distribution in accordance with the provisions of Section 4(d). Until such time as such Collateral or proceeds have been delivered in accordance with the preceding sentence, each such Lender or Agent shall hold such Collateral and proceeds in trust for the Collateral Agent. (k) If any Lender or Agent exercises any right of set-off, banker's lien or similar right with respect to any Collateral for payment of any of the EPN Loan Obligations, EPNHC Loan Obligations, Senior Secured Acquisition Term Loan Obligations or Clawback Obligation, the amounts so set off shall constitute Collateral for purposes of this Agreement, and such Lender or Agent shall promptly cause such amounts to be delivered to or put in the custody, possession or control of the Collateral Agent as provided in Section 4(j) above. Until such time as such Collateral or proceeds have been delivered in accordance with the Section 4(j) above, each such Lender or Agent shall hold such Collateral and proceeds in trust for the Collateral Agent. (l) If, after the occurrence and during the continuance of a Default or Event of Default (as each is defined in each of the EPN Group Credit Agreements and the Marco Polo Credit Agreement), the EPN Lenders, the EPNHC Lenders, the Senior Secured Acquisition Term Loan Lenders, the Marco Polo Lenders, any of the EPN Group Administrative Agents or the Marco Polo Administrative Agent (the receiving parties, the "benefited Lenders", the non-receiving parties, the "non-benefited Lenders") shall at any time receive by set-off any payment of all or part of any of the EPN Group Loans or Loans (as defined in the Marco Polo Credit Agreement) owing to them or it, or interest thereon, or receive any collateral in respect thereof, in a greater proportion than any such payment to or collateral received by the non-benefited Lenders, if any, in respect of such non-benefited Lenders EPN Group Loans or Loans (as the latter is defined in the Marco Polo Credit Agreement) of the same type owing to it, as the case may be, or interest thereon, the benefited Lenders shall purchase for cash from the non-benefited Lenders a participating interest in such portion of each such non-benefited Lender's Loan owing to it, or shall provide such non-benefited Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the non-benefited Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. After the occurrence and during the continuance of a Default or Event of Default (as each is defined in each of the EPN Group Credit Agreements and the Marco Polo Credit Agreement), in the event of any conflict between this Section 4(l), on the one hand, and Section 11.7 of each of the EPN Group Credit Agreements and Section 9.08 of the Marco Polo Credit Agreement, on the other hand, this Section 4(l) shall govern. (m) No holder of any of the EPN Loan Obligations, EPNHC Loan Obligations, Senior Secured Acquisition Term Loan Obligations or Clawback Obligation may require the Collateral Agent to take or refrain from taking any action hereunder or under any of the EPN Group Security Documents or with respect to any of the Collateral except as and to the extent expressly set forth in this Agreement or in the EPN Group Security Documents. The Collateral Exhibit K-13

Agent shall have no duty to, and each Lender hereby waives any and all right to require the Collateral Agent to, marshal any assets of the EPN Group Loan Parties or otherwise take any action with respect to marshaling. 5. EFFECT OF COVENANTS IN MARCO POLO DOCUMENTS. The Marco Polo Administrative Agent hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Marco Polo Loan Document shall be deemed to restrict in any way the rights and remedies of the Collateral Agent with respect to the Collateral as set forth in this Agreement and the EPN Group Security Documents. 6. OBLIGATIONS UNCONDITIONAL. All rights and interests of the parties hereunder, and all agreements and obligations of the parties hereunder, shall remain in full force and effect irrespective of: (a) any lack of validity or enforceability of any EPN Loan Documents, any EPNHC Loan Documents, any Senior Secured Acquisition Term Loan Documents or any Marco Polo Loan Documents; (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations, the Clawback Obligation or any amendment or waiver or other modification, whether by course of conduct or otherwise, of the terms of any EPN Loan Document, any EPNHC Loan Document, any Senior Secured Acquisition Term Loan Document or any Marco Polo Loan Document; provided, however, that the aggregate Clawback Obligation shall not in any event exceed $22,500,000; (c) any exchange, release or nonperfection of any security interest in any Collateral, or any release, amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations or the Clawback Obligation; (d) the commencement of any bankruptcy or similar proceeding in respect of EPN, EPNHC or any other EPN Group Loan Party; or (e) any other circumstances which otherwise might constitute a defense available to, or a discharge of, any EPN Group Loan Party in respect of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations or the Clawback Obligation. 7. WAIVER OF CLAIMS AND INDEMNIFICATION. (a) To the maximum extent permitted by law, the Marco Polo Administrative Agent and the Marco Polo Lenders waive any claim any of them might have against the Collateral Agent, the EPN Group Administrative Agents or the EPN Group Lenders with respect to, or arising out of, any action or failure to act or any error of judgment, negligence, or mistake or oversight whatsoever on the part of the Collateral Agent, the EPN Group Administrative Agents, the EPN Group Lenders or their respective directors, officers, employees or agents with respect to any exercise of rights or remedies under the EPN Loan Documents, the EPNHC Loan Documents, the Senior Secured Acquisition Term Loan Documents or any transaction relating to the Collateral. Neither the Collateral Agent, the EPN Exhibit K-14

Administrative Agent, EPNHC Administrative Agent, the Senior Secured Acquisition Term Loan Administrative Agent or any EPN Group Lender nor any of their respective directors, officers, employees or agents shall be liable to the Marco Polo Administrative Agent or the Marco Polo Lenders for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Marco Polo Administrative Agent or the Marco Polo Lenders or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. (b) Without limiting the indemnity obligations of the EPN Group Lenders under the EPN Loan Documents, the EPNHC Loan Documents, the Senior Secured Acquisition Term Loan Documents and the Marco Polo Lenders under the Marco Polo Loan Documents, the Lenders, each of the EPN Group Administrative Agents and the Marco Polo Administrative Agent agree to indemnify the Collateral Agent in its capacity as collateral agent under this Agreement and the EPN Group Security Documents (to the extent not reimbursed by the EPN Group Loan Parties and without limiting the obligation of the EPN Group Loan Parties to do so), ratably according to their respective interests in the aggregate of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations and the Clawback Obligation in effect on the date on which indemnification is sought under this subsection, 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 EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations and Marco Polo Bank Obligations) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of this Agreement, the Collateral or any EPN Group Security Document 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 solely from the Collateral Agent's gross negligence or willful misconduct. The agreements in this subsection shall survive the payment of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations and the Marco Polo Bank Obligations. (c) No Marco Polo Lender shall be entitled to the benefits of this Agreement, any EPN Group Security Document or to the collateral security provided by the Collateral unless such Marco Polo Lender has agreed in writing to be bound by the provisions of this Agreement. (d) Each Marco Polo Lender and the Marco Polo Administrative Agent agree, that, with respect to the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations, any and all guaranties thereof and any and all Collateral, the EPN Group Loan Parties, the EPN Group Lenders, the EPN Group Administrative Agents and the Collateral Agent may agree to (i) increase the amount of the EPN Loan Obligations, the EPNHC Loan Obligations, the Senior Secured Acquisition Term Loan Obligations or otherwise modify or waive the terms of any of the EPN Loan Documents, the EPNHC Loan Documents or the Senior Secured Acquisition Term Loan Documents or (ii) grant extensions of the time of payment or performance of and make compromise in respect of the Exhibit K-15

USE OF COLLATERAL PRIOR TO EVENTS OF DEFAULT. So long as no Event of Default (as defined in each of the EPN Group Credit Agreements) shall have occurred and be continuing, the EPN Group Loan Parties shall have the right as provided under the EPN Group Security Documents: (i) to remain in possession and retain exclusive control of the Collateral (other than Collateral for which the security interest granted therein is perfected solely by possession or control under the Uniform Commercial Code) with power to operate, manage, develop, use and enjoy the Collateral as permitted in the EPN Group Credit Agreements and to receive rents, issues, tolls, profits, royalties, revenues and other income thereof and (ii) subject to Section 9 below, to sell or otherwise dispose of, free and clear of any Lien and security interest created by the EPN Group Security Documents, any Collateral. The Collateral Agent shall have no duty to monitor the exercise by the EPN Group Loan Parties of their rights in the Collateral under the EPN Group Credit Agreements, the EPN Group Security Documents or this Agreement. 9. RELEASES. (a) So long as no Event of Default (as defined in each of the EPN Group Credit Agreements) shall have occurred and be continuing, Collateral shall be released from the Lien and security interests created by the EPN Group Security Documents at any time or from time to time, (i) in connection with any sale or other disposition that is permitted by Section 8.6 of each of the EPN Group Credit Agreements, (ii) with the written consent of the Required EPN Group Lenders (or to the extent required by clause (iv) of the proviso to Section 11.1 of each of the EPN Group Credit Agreements, the EPN Lenders, the Senior Secured Acquisition Term Loan Lenders, or the EPNHC Lenders, as applicable), or (iii) in accordance with Section 19(b). No such permitted sales or other dispositions or other permitted releases of Collateral shall require any written or oral release or consent of the Collateral Agent. Nevertheless, any EPN Group Loan Party may request that the Collateral Agent execute and deliver to such EPN Group Loan Party or any permitted purchaser of Collateral, a written release or termination of the Collateral Agent's interest in any Collateral under the EPN Group Security Documents (including, without limitation, any termination statements to be filed pursuant to the Uniform Commercial Code). Such request shall be in writing signed by a Responsible Officer of such EPN Group Loan Party, shall describe the property to be released in reasonable detail and shall state that such release (x) is in accordance with Section 8.6 of each of the EPN Group Exhibit K-17

Credit Agreements, or (y) has been consented to in writing by the Required EPN Group Lenders (or to the extent required by clause (iv) of the proviso to Section 11.1 of the EPN Group Credit Agreements, the EPN Lenders, the EPNHC Lenders or the Senior Secured Acquisition Term Loan Lenders, as applicable), a copy of which consent shall be attached. (b) If any Collateral which is being released pursuant to Section 9 is in the possession of the Collateral Agent or one of its agents or nominees, the Collateral Agent or such agent or nominee shall release such Collateral to the relevant EPN Group Loan Party in connection with such sale or disposition upon (i) a written request signed by a Responsible Officer of such EPN Group Loan Party in the form of the request described in Section 9(a).

The Collateral Agent in so doing shall have no liability therefore to any Person. 10. PROVISIONS DEFINING RELATIVE RIGHTS.

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. Prior 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 Exhibit O-1

to terms of existing gathering agreements), (b) Field Services became obligated to attempt to acquire additional processing rights for 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. III. Current Status of Chaco Plant As of the Closing Date, after giving effect to the Transaction, the Borrower will have acquired, indirectly through its Restricted Subsidiaries, the entire remaining interest in the Chaco Plant.
