El Paso Energy Partners Finance Corporation
4 Greenway Plaza, Suite 652
Houston, TX  77046

Attention: Mr. Keith Forman

Ladies and Gentlemen:

                  Reference is made to the Senior Secured Acquisition Term Loan
Credit Agreement dated as of November 27, 2002 (the "Credit Agreement"), by and
among El Paso Energy Partners, L.P. (the "Borrower"), El Paso Energy Partners
Finance Corporation (the "Co-Borrower"), the lenders and financial institutions
party thereto (the "Lenders"), Goldman Sachs Credit Partners L.P., as
documentation agent, UBS Warburg LLC and Wachovia Bank, National Association, as
co-syndication agents, and JPMorgan Chase Bank, as administrative agent.
Capitalized terms not defined herein are used with the meanings assigned to them
in the Credit Agreement. This letter agreement is the "Securities Demand Letter
Agreement" referred to in Section 4.15 of the Credit Agreement. It is a
condition precedent to the funding of the Loans under the Credit Agreement that
the Borrower execute and deliver this Securities Demand Letter Agreement.

                  Reference is also made to that certain engagement letter dated
as of November 22, 2002 by and among the Borrower, J.P. Morgan Securities Inc.,
Goldman, Sachs & Co., UBS Warburg LLC and Wachovia Securities, Inc. pursuant to
which the Borrower has engaged the other parties thereto (collectively, the
"Investment Bank") to publicly sell or privately place an amount to be
determined by the Borrower but not less than $437,500,000 aggregate principal
amount of debt securities (which may include cash pay or non-cash pay
securities, senior or senior subordinated securities, discount issue securities
or a combination of any of the foregoing) (the "Securities") of the Borrower or
any of its Subsidiaries.

                  In connection with the Acquisition and the Transaction, a
portion of the Securities in a face amount equal to $200,000,000 were issued as
the Senior Subordinated Notes comprising the Acquisition Offering, the net
proceeds of which were used to provide funds for

the consummation of the Transaction on the Closing Date. The Borrower hereby
agrees, for the benefit of the Lenders, to take any and every action reasonably
necessary or desirable specified upon written notice to the Borrower from the
Investment Bank so that the Investment Bank can, as soon as practicable after
the Closing Date, publicly sell or privately place, in one or more offerings or
placements, the remaining Securities, the net proceeds of which shall be used to
prepay the Loans pursuant to the terms of Section 4.1(b) of the Credit
Agreement.

                  In any event, upon written notice by JPMorgan and any other
Initial Lender (that is a Lender at such time) delivered to the Investment Bank
and the subsequent written demand by the Investment Bank (a "Securities Demand")
to the Borrower (a) at any time following the date that is six months after the
Closing Date and from time to time thereafter if all of the Loans have not been
repaid in full, the Borrower (and the Co-Borrower) will cause the issuance and
sale of Securities in an amount equal to not less than 50% of the outstanding
balance of the Loans at the time of such Securities Demand upon such terms and
conditions as may specified by the Investment Bank in the applicable Securities
Demand and (b) at any time following the date that is the anniversary of the
Closing Date and from time to time thereafter if all of the Loans have not been
repaid in full, the Borrower (and the Co-Borrower) will cause the issuance and
sale of Securities in an amount equal to not less than the remaining outstanding
balance of the Loans at the time of such Securities Demand upon such terms and
conditions as may specified by the Investment Bank in the applicable Securities
Demand; provided, however, that in each case of clauses (a) and (b) above (i)
the interest rate (whether floating or fixed) shall be determined by the
Investment Bank in light of the then-prevailing market conditions for comparable
securities but in no event shall the effective yield on such Securities exceed
the greater of (A) 13% per annum and (B) on the day of pricing of such
Securities, the "Yield to Worst" on the Borrower's 8-1/2% Senior Subordinated
Notes due 2011 plus 1.5% per annum; (ii) the Investment Bank, in its reasonable
discretion after consultation with the Borrower, shall determine whether the
Securities shall be issued through a public offering or a private placement;
(iii) the maturity of any Securities shall not be earlier than six months after
the final maturity of the Initial Term Loans (as such term is defined in the EPN
Credit Agreement); (iv) the Securities will be issued pursuant to an indenture
or indentures, which shall contain such terms, conditions and covenants as are
typical and customary for similar financings and as the Investment Bank, the
Borrower and the Administrative Agent shall reasonably determine to be
satisfactory in all respects, including, without limitation, one of the
Borrower's then existing Senior Subordinated Notes Indentures; (v) all other
arrangements with respect to the Securities issued pursuant to a Securities
Demand made under this Securities Demand Letter Agreement as the Investment Bank
shall reasonably determine to be satisfactory in light of the then prevailing
market conditions; (vi) the Net Proceeds of such issuance and sale of Securities
shall be applied as a prepayment to the Loans pursuant to the terms of Section
4.1(b) of the Credit Agreement; (vii) the issuance and sale of Securities
pursuant to a Securities Demand or pursuant to the previous paragraph shall not
cause a Default or Event of Default; and provided further, that the Borrower
shall take any and every action reasonably necessary or desirable so that the
issuance and sale of Securities pursuant to a Securities Demand or pursuant to
the previous paragraph shall not cause a Default or Event of Default; and (viii)
upon the request of the Borrower, the Investment Bank or the Administrative
Agent, as applicable, shall promptly notify the Borrower of any matters that are
required to be determined by the Investment Bank or the Administrative Agent
pursuant to this paragraph. The Investment Bank is hereby authorized to rely on
the provisions of this Securities

shall be an original, and all of which, when taken together, shall constitute

<PAGE>

                                   ARTICLE I
                                  DEFINITIONS

         Section 1.1       Defined Terms. As used in this Agreement, the
following terms shall have the following meanings:

         "Acquired Business": as defined in subsection 8.8(e).

         "Acquisition": the acquisition and purchase by the Borrower from El
Paso or its Subsidiaries of (i) all of the equity interests in ANR Central, EP

equity interest in Coyote Gas, (iii) certain residual interests related to the
Chaco cryogenic plant, and (iv) the Typhoon Oil Gathering System, for an
aggregate consideration of up to $782,000,000, subject to closing adjustments,
pursuant to the terms and conditions of the Acquisition Document.

         "Acquisition Document": the Contribution, Purchase and Sale Agreement,
by and between El Paso, as seller, and the Borrower, as buyer, dated as of
November 21, 2002 governing the terms and conditions of the Acquisition.

         "Acquisition Offering": as defined in the Recitals hereto.

         "Administrative Agent": as defined in the introductory paragraph of
this Agreement.

         "Administrative Questionnaire": an Administrative Questionnaire in a
form supplied by the Administrative Agent.

         "Affiliate": as to any Person, any other Person (other than a

"control" of a Person means the power, directly or indirectly, either to (i)
vote 10% or more of the securities having ordinary voting power for the election
of directors (or similar authority) of such Person or (ii) direct or cause the
direction of the management and policies of such Person, whether by contract or
otherwise; provided, that any third Person which also beneficially owns 10% or
more of the securities having ordinary voting power for the election of
directors (or similar authority) of a Joint Venture or Subsidiary shall not be
deemed to be an Affiliate of the Borrower and its Subsidiaries or Joint Ventures
merely because of such common ownership.

         "Agreement": this Senior Secured Acquisition Term Loan Credit
Agreement, as amended, supplemented or otherwise modified from time to time.

         "Alternate Base Rate": for any day, a rate per annum (rounded upwards,
if necessary, to the next 1/16 of 1%) equal to the greater of (a) the Prime Rate
in effect on such day and (b) the Federal Funds Effective Rate in effect on such
day plus 1/2 of 1%. For purposes hereof: "Prime Rate" shall mean the rate of

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

which is based upon the Alternate Base Rate.

Standard & Poor's Ratings Services (or any successor statistical rating
organization) ("S&P") or Moody's Investors Service, Inc. (or any successor

bank debt of the Borrower in effect at the time of such determination.

         "Approved Fund": any Person (other than a natural person) that is (or
will be) engaged in making, holding or otherwise investing in commercial loans

                            AMOUNT AND TERMS OF LOANS

         Section 2.1       Loans.

                  (a)      Subject to the terms and conditions hereof, each
Lender severally agrees to make, on the Closing Date, a senior secured
acquisition term loan (collectively, the "Loans") to the Borrower in an
aggregate principal amount not to exceed such Lender's Commitment. Once repaid,
Loans may not be reborrowed.

                  (b)      The Loans may from time to time be (i) Eurodollar
Loans, (ii) Alternate Base Rate Loans or (iii) a combination thereof, as
determined by the Borrower and notified to the Administrative Agent in
accordance with Sections 2.3 and 4.2, provided that no Loan shall be made as a
Eurodollar Loan after the day that is one month prior to the Maturity Date.

         Section 2.2       Repayment of Loans; Evidence of Debt.

                  (a)      The Borrower hereby unconditionally promises to pay
to the Administrative Agent for the account of each Lender the then unpaid
principal amount of each Loan on the Maturity Date (or such earlier date on
which the Loans become due and payable pursuant to Article IX).

                  (b)      Each Lender shall maintain in accordance with its
usual practice an account or accounts evidencing the indebtedness of the
Borrower to such Lender resulting from each Loan made by such Lender, including
the amounts of principal and interest payable and paid to such Lender from time
to time hereunder.

                  (c)      The Administrative Agent shall maintain accounts in
which it shall record (i) the amount of each Loan made hereunder; the Type
thereof; and the Interest Period applicable to each Loan made or maintained
hereunder, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for the account
of the Lenders and each Lender's share thereof.

                  (d)      The entries made in the accounts maintained pursuant
to paragraph (b) or (c) of this Section 2.2 shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans in accordance with the terms of this Agreement.

                  (e)      Any Lender may request that Loans made by it be
evidenced by a promissory note. In such event, the Borrower shall prepare,
execute and deliver to such Lender a promissory note substantially in the form
of Exhibit A hereto (a "Note"), as applicable, payable to the order of such
Lender. Thereafter, the Loans evidenced by any such promissory note and interest
thereon shall at all times (including after assignment pursuant to Section 11.6)
be represented by one or more promissory notes in such form payable to the order
of the payee named therein.

         Section 2.3       Procedure for Borrowing.   The Borrower may borrow
under the Commitments on the Closing Date, provided that the Borrower shall give
the Administrative Agent irrevocable notice (which notice must be received by
the Administrative Agent prior to 10:00 A.M., New York City time, one Business
Day prior to the Closing Date), specifying (i) the amount to be borrowed, (ii)
that such Loans shall be incurred on the Closing Date, and (iii) that such
borrowing is to be of Alternate Base Rate Loans. Upon receipt of such notice
from the Borrower, the Administrative Agent shall promptly notify each Lender
thereof. Each Lender will make the amount of its pro rata share of the borrowing
available to the Administrative Agent for the account of the Borrower at the
office of the Administrative Agent specified in Section 11.2 prior to 2:00 P.M.,
New York City time, on the Closing Date in funds immediately available to the
Administrative Agent. Such borrowing will then be made available to the Borrower
by the Administrative Agent crediting the account of the Borrower on the books
of such office with the aggregate of the amounts made available to the
Administrative Agent by the Lenders and in like funds as received by the
Administrative Agent.

         Section 2.4       Limitation on Loans.   No requested Loan shall be
made if (after giving effect to such requested Loan and all other Loans
comprising the borrowing of which it is a part) the Loans would exceed the
aggregate Commitments.

         Section 2.5       Termination of Commitments.   Any and all of the
Commitments remaining unused shall automatically terminate at 5:00 P.M., New
York City time, on the Closing Date.

                                   [RESERVED]

                          GENERAL PROVISIONS FOR LOANS

         Section 4.1       Optional and Mandatory Prepayments.

                  (a)      The Borrower may on the last day of any Interest
Period with respect thereto (or at other times with the payment of applicable
breakage costs), in the case of Eurodollar Loans, or at any time and from time
to time, in the case of Alternate Base Rate Loans, prepay the Loans, in whole or
in part, without premium or penalty, upon at least four Business Days'
irrevocable notice to the Administrative Agent, specifying (i) the date and
amount of prepayment and (ii) whether the prepayment is of Eurodollar Loans,
Alternate Base Rate Loans or a combination thereof, and, if of a combination
thereof, the amount allocable to each. Upon receipt of any such notice the
Administrative Agent shall promptly notify each Lender thereof. If any such
notice is given, the amount specified in such notice shall be due and payable on
the date specified therein, with accrued interest to such date on the amount
prepaid in the case of prepayment of the Loans. Partial prepayments of the Loans
shall be in an aggregate principal amount of $5,000,000 or a whole multiple
thereof.

                  (b)      Subject to subsection (d) below, at any time after
the Closing Date that the Co-Borrower, the Borrower or any of its Restricted
Subsidiaries shall receive cash Net Equity Proceeds from any issuance or sale of
Capital Stock or i-shares or Net Proceeds from any

                                       27

<PAGE>

issuance or sale of debt securities issued by the Borrower or its Restricted
Subsidiaries pursuant to existing or future Senior Subordinated Notes Indentures
or any senior notes indentures, the Borrower shall repay the Loans on the date
such proceeds are received in an amount equal to 100% of such cash Net Equity
Proceeds or Net Proceeds, as the case may be.

                  (c)      At any time the General Partner, the Borrower or any
Restricted Subsidiary of the Borrower shall receive net proceeds from any
Purchase Price Adjustment, the Borrower shall repay the Loans on the date such
proceeds are received in an amount equal to 100% of such net proceeds.

                  (d)      For purposes of Section 4.1(b), Net Equity Proceeds
of any of the following issuances of Capital Stock by the Borrower or any of its
Restricted Subsidiaries shall not be required to be applied in prepayment of the
Loans:

                           (i)      issuances in connection with the Equity
Investment;

                           (ii)     issuances upon the exercise of any options
or warrants to purchase equity securities of the Borrower or its Restricted
Subsidiaries;

                           (iii)    issuances to the management of (A) the
Borrower or (B) its Restricted Subsidiaries;

                           (iv)     issuances made in connection with an
acquisition directly to the seller of the assets being acquired in such
acquisition; or

                           (v)      issuances to the Borrower or its Restricted
Subsidiaries.

         Section 4.2       Conversion and Continuation Options.

                  (a)      The Borrower may elect from time to time to convert
Eurodollar Loans to Alternate Base Rate Loans by giving the Administrative Agent
at least two Business Days' prior irrevocable notice of such election, provided
that any such conversion of Eurodollar Loans may only be made on the last day of
an Interest Period with respect thereto. The Borrower may elect from time to
time to convert Alternate Base Rate Loans to Eurodollar Loans by giving the
Administrative Agent at least three Working Days' prior irrevocable notice of
such election. Any such notice of conversion to Eurodollar Loans shall specify
the length of the initial Interest Period or Interest Periods therefor. Upon
receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof. All or any part of outstanding Eurodollar Loans and Alternate
Base Rate Loans may be converted as provided herein, provided that (i) no Loan
may be converted into a Eurodollar Loan when any Default or Event of Default has
occurred and is continuing and the Administrative Agent has or the Required
Lenders have determined that such a conversion is not appropriate, (ii) any such
conversion may only be made if, after giving effect thereto, Section 4.3 shall
not have been contravened and (iii) no Loan may be converted into a Eurodollar
Loan after the date that is one month prior to the Maturity Date.

                  (b)      Any Eurodollar Loans may be continued as such upon
the expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period"

                                       28

<PAGE>

set forth in Section 1.1, of the length of the next Interest Period to be
applicable to such Loans, provided that no Eurodollar Loan may be continued as
such (i) when any Default or Event of Default has occurred and is continuing and
the Administrative Agent has or the Required Lenders have determined that such a
continuation is not appropriate, (ii) if, after giving effect thereto, Section
4.3 would be contravened or (iii) after the date that is one month prior to the
Maturity Date, and provided, further, that if the Borrower shall fail to give
any required notice as described above in this paragraph or if such continuation
is not permitted pursuant to the preceding proviso such Loans shall be
automatically converted to Alternate Base Rate Loans on the last day of such
then expiring Interest Period.

         Section 4.3       Minimum Amounts of Tranches. All borrowings,
conversions and continuations of Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, (a) the aggregate principal
amount of the Loans comprising each Tranche shall be equal to $2,000,000 or a
whole multiple of $100,000 in excess thereof, and (b) the number of Tranches
then outstanding shall not exceed eight.

         Section 4.4       Interest Rates and Payment Dates.

                  (a)      Each Eurodollar Loan shall bear interest for each day
during each Interest Period with respect thereto at a rate per annum equal to
the Eurodollar Rate determined for such day plus the Applicable Margin.

                  (b)      Each Alternate Base Rate Loan shall bear interest at
a rate per annum equal to the Alternate Base Rate plus the Applicable Margin.

                  (c)      If all or a portion of (i) the principal amount of
any Loan, (ii) any interest payable thereon or (iii) any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is the higher of (A) the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this Section 4.4 plus
2% and (B) the Alternate Base Rate plus 1%, in each case from the date of such
non-payment until such amount is paid in full (as well after as before
judgment).

                  (d)      Interest shall be payable in arrears on each Interest
Payment Date, on any prepayment (on the amount prepaid) and at maturity (whether
by acceleration or otherwise), provided that interest accruing pursuant to
paragraph (c) of this Section 4.4 shall be payable from time to time on demand.

         Section 4.5       Computation of Interest and Fees.

                  (a)      Interest on Alternate Base Rate Loans and interest on
overdue interest and other amounts payable hereunder shall be calculated on the
basis of a 365- (or 366-, as the case may be) day year for the actual days
elapsed. Interest on Eurodollar Loans and fees shall be calculated on the basis
of a 360-day year for the actual days elapsed. The Administrative Agent shall as
soon as practicable notify the Borrower and the Lenders of each determination of
a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the Alternate Base Rate or the Eurocurrency Reserve Requirements shall
become effective as of the

                                       29

<PAGE>

opening of business on the day on which such change becomes effective. The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of the effective date and the amount of each such change in interest
rate.

                  (b)      Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to subsection
4.4(a).

         Section 4.6       Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                  (a)      the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances 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

<PAGE>

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

<PAGE>

                           (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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

         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

<PAGE>

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. All proceeds of the Loans shall be
used on the Closing Date by the Borrower to finance a portion of the Acquisition
and to pay related fees and expenses.

         Section 5.17      Environmental Matters. 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

<PAGE>

could reasonably be expected to give rise to liability under, any applicable
Environmental Law except insofar as any such violation or liability referred to
in this paragraph, or any aggregation thereof, could not reasonably be expected
to result in the payment of a Material Environmental Amount.

                  (e)      No judicial proceeding or governmental or
administrative action is pending or, to the knowledge of the Borrower,
threatened, under any Environmental Law to which the Borrower or any Subsidiary,
or, to the best knowledge of the Borrower, any Joint Venture, is or will be
named as a party with respect to the Properties or the Business, nor are there
any consent decrees or other decrees, consent orders, administrative orders or
other orders, or other administrative or judicial requirements outstanding under
any Environmental Law with respect to the Properties or the Business except
insofar as such proceeding, action, decree, order or other requirement, or any
aggregation thereof, could not reasonably be expected to result in the payment
of a Material Environmental Amount.

                  (f)      To the best knowledge of the Borrower, there has been
no release or threat of release of Materials of Environmental Concern at or from
the Properties, or arising from or related to the operations of the Borrower or
any Subsidiary or any Joint Venture, in connection with the Properties or
otherwise in connection with the Business, in violation of or in amounts or in a
manner that could give rise to liability under Environmental Laws except insofar
as any such violation or liability referred to in this paragraph, or any
aggregation thereof, could not reasonably be expected to result in the payment
of a Material Environmental Amount.

                  (g)      There are no Liens arising under or pursuant to any
Environmental Laws on any of the real properties or properties owned or leased
by any Loan Party, and no government actions have been taken or are in process

Hazardous Materials at any properties owned by it in any deed to such
properties.

                  (h)      There have been no environmental investigations,
studies, audits, tests, reviews or other analyses conducted by or which are in

         Section 5.18      Accuracy and Completeness of Information. The factual
statements contained in the financial statements (other than financial
projections) referred to in Section 5.1, the Loan Documents, the Offering
Memorandum with respect to the Acquisition Offering dated as of November 22,
2002 and any other certificates or documents furnished or to be furnished (but
only, with respect to documents furnished after the Closing Date, documents
provided pursuant to subsection 7.2(d)) to the Administrative Agent or the
Lenders from time to time in connection with this Agreement, taken as a whole,
do not and will not, to the knowledge of the Borrower, as of the date when made,
contain any untrue statement of a material fact or omit to state a material fact
(other than omissions that pertain to matters of a general economic nature,
matters generally known to the Administrative Agent or matters of public
knowledge that generally affect any of the industry segments included in the
Business of the Borrower, its Subsidiaries or any Joint Venture) necessary in
order to make the statements contained therein not misleading in light of the
circumstances in which the same were made, such knowledge

qualification being given only with respect to factual statements made by
Persons other than the Borrower, and all financial projections contained in any
such document or certificate have been prepared in good faith based upon
assumptions believed by the Borrower to be reasonable.

         Section 5.19      Security Documents. The Pledge Agreements are each
effective to create in favor of the Collateral Agent, for the ratable benefit of
the EPN Group Lenders and the Marco Polo Lenders, a legal, valid and enforceable

                                   ARTICLE X
                            THE ADMINISTRATIVE AGENT

         Section 10.1      Appointment. Each Lender hereby irrevocably
designates and appoints JPMorgan as the Administrative Agent of such Lender
under this Agreement and the other Loan Documents, and each such Lender
irrevocably authorizes JPMorgan, as the Administrative Agent for such Lender, to
take such action on its behalf under the provisions of this Agreement and the
other Loan Documents and to exercise such powers and perform such duties as are
expressly delegated to the Administrative Agent by the terms of this Agreement
and the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the 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. The Administrative
Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

         Section 10.3      Exculpatory Provisions. 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 not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of the Borrower.

         Section 10.4      Reliance by Administrative Agent. 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

<PAGE>

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 be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The 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. The Administrative Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default hereunder unless the Administrative Agent has received notice from a
Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". 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

<PAGE>

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

<PAGE>

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.

                                   ARTICLE XI
                                  MISCELLANEOUS

         Section 11.1      Amendments and Waivers. None of this Agreement or any
other Loan Document and any terms hereof or thereof may be amended, supplemented
or modified except in accordance with the provisions of this Section 11.1. The
Required Lenders may, or, with the written consent of the Required Lenders, the
Administrative Agent may, from time to time, (a) enter into with the Borrower or
any other applicable Loan Party written amendments, supplements or modifications
hereto and to the other Loan Documents for the purpose of adding any provisions
to this Agreement or the other Loan Documents or changing in any manner the
rights of the Lenders or of the Borrower or any other Loan Party hereunder or
thereunder or (b) waive in writing, on such terms and conditions as the Required
Lenders or the Administrative Agent, as the case may be, may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such waiver and no such amendment, supplement or modification
shall (i) reduce the amount or extend the scheduled date of maturity of any
Loan, or reduce the stated rate of any interest or fee payable hereunder or
extend the scheduled date of any payment thereof or increase the amount or
extend the expiration date of any Lender's Commitment, in each case without the
consent of each Lender affected thereby, or (ii) amend, modify or waive any
provision of this Section 11.1 or reduce the percentage specified in the
definition of Required Lenders, or consent to the assignment or transfer by the
Borrower of any of its rights and obligations under this Agreement and the other
Loan Documents (except in a transaction permitted by Section 8.5), in each case
without the written consent of all the Lenders, or (iii) amend, modify or waive
any provision of Article X without the written consent of the then
Administrative Agent, or (iv) release the Lenders' Liens on all or substantially
all of the Collateral under the Security Documents without the consent of each
Lender or (v) except to the extent relating to the Redesignation of any
Restricted Subsidiary, the sale or other disposition of any Restricted
Subsidiary as otherwise permitted by this Agreement or any other transaction
permitted by this Agreement, release any Guarantee. Any such waiver and any such
amendment, supplement or modification shall apply equally to each of the Lenders
and shall be binding upon the Borrower, the Lenders, the Administrative Agent
and all future holder of the Notes. In the case of any waiver, the Borrower, the
Lenders and the Administrative Agent shall be restored to their former position
and rights hereunder and under the outstanding Notes and any other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon.

         Section 11.5      Payment of Expenses and Taxes. The Borrower agrees
(a) to pay or reimburse the Administrative Agent and the Collateral Agent for
all their respective reasonable out-of-pocket costs and expenses incurred in
connection with the development, preparation and

                                       74

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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

         To the extent that Article 5069-1D.001 et seq., as amended, of the
Texas Revised Civil Statutes is relevant to the Administrative Agent and the
Lenders for the purpose of determining the Highest Lawful Rate, the
Administrative Agent and the Lenders hereby elect to determine the applicable
rate ceiling under such Article by the indicated (weekly) rate ceiling from time
to time in effect. Nothing set forth in this Section 11.11 is intended to or
shall limit the effect or operation of Section 11.12. In no event shall Chapter
346 of the Texas Finance Code (which regulates certain revolving credit loan
accounts) apply to this Agreement or the Notes.

         For purposes of this Section 11.11, "Highest Lawful Rate" shall mean
the maximum rate of nonusurious interest that may be contracted for, charged,
taken, reserved or received hereunder under laws applicable to the
Administrative Agent and the Lenders.

         Section 11.12     GOVERNING LAW. THIS AGREEMENT AND THE NOTES AND THE
RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL
BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK.

         Section 11.13     Submission To Jurisdiction; Waivers. The Borrower
hereby irrevocably and unconditionally:

                  (a)      submits for itself and its property in any legal
action or proceeding relating to this Agreement and the other Loan Documents to
which it is a party, or for recognition and enforcement of any judgment in
respect thereof, to the non-exclusive general jurisdiction of the Courts of the
State of New York, the courts of the United States of America for the Southern
District of New York, and appellate courts from any thereof;

                  (b)      consents that any such action or proceeding may be
brought in such courts and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

                  (c)      agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at its address set forth in Section 11.2 or at such other address of
which the Administrative Agent shall have been notified pursuant thereto;

                  (d)      agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                  (e)      waives, to the maximum extent not prohibited by law,
any right it may have to claim or recover in any legal action or proceeding
referred to in this Section any special, exemplary or punitive damages
(including, without limitation, damages arising from the use of electronic,
telecommunications or other information transmissions systems in connection with
the Loan Documents).

         Section 11.14     Acknowledgements. The Borrower hereby acknowledges
that:

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

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.

         Section 11.17     ACKNOWLEDGEMENT OF NO CLAIMS, OFFSETS OR DEFENSES;
RELEASE BY THE LOAN PARTIES. BORROWER, ON BEHALF OF ITSELF AND EACH OF THE OTHER
LOAN PARTIES, ACKNOWLEDGES THAT NO LOAN PARTY NOR ANY OF THEIR RESPECTIVE
OWNERS, DIRECTORS, SUCCESSORS, ASSIGNS, AGENTS, OFFICERS, EMPLOYEES, AND
REPRESENTATIVES (COLLECTIVELY, THE "BORROWER 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

AND LENDERS ("THE PRIOR AGREEMENTS AND ACTIVITIES"). NOTWITHSTANDING THE
FOREGOING, HOWEVER, BORROWER HEREBY AGREES THAT IN CONSIDERATION OF THE CREDIT
EXTENDED TO BORROWER UNDER THE LOAN DOCUMENTS AND AS A MATERIAL INDUCEMENT TO
THE LENDERS TO ENTER INTO SUCH LOAN DOCUMENTS AND EXTEND SUCH CREDIT TO
BORROWER, BORROWER, ON BEHALF OF ITSELF AND ALL OF THE OTHER BORROWER AFFILIATED
PARTIES HEREBY RELEASES AND FOREVER DISCHARGES, EACH LENDER, EACH SUBSEQUENT
HOLDER OF ANY OF THE NOTES, AND EACH AND ALL OF THEIR PARENT, SUBSIDIARY AND
AFFILIATED CORPORATIONS PAST AND PRESENT, AS WELL AS THEIR RESPECTIVE OWNERS,
DIRECTORS, SUCCESSORS, ASSIGNS, AGENTS, OFFICERS, EMPLOYEES, AND REPRESENTATIVES
(COLLECTIVELY, THE "RELEASED PARTIES"), OF AND FROM ANY AND ALL CLAIMS WHICH
BORROWER AND THE OTHER BORROWER AFFILIATED PARTIES MAY HAVE OR HEREAFTER ACQUIRE
AGAINST ANY OR ALL OF THE RELEASED PARTIES BY REASON OF, OR RELATED IN ANY WAY
TO, THE PRIOR AGREEMENTS AND ACTIVITIES.

         Section 11.18     Releases.

                  (a)      At such time as the Loans and any other obligations
under this Agreement shall have been paid in full, the Collateral shall be
released from the Liens created by the Loan Documents, and all obligations
(other than those expressly stated to survive such termination) of the
Administrative Agent, the Collateral Agent and each Loan Party thereunder and
under the other Loan Documents shall terminate, all without delivery of any
instrument or performance of any act by any party, and all rights to the
Collateral shall revert to the respective Loan Parties. At the request and
expense of any Loan Party following any such termination, the Collateral Agent
shall deliver to such Loan Party any Collateral held by the Collateral Agent
under the Security Documents, and execute and deliver to such Loan Party such
documents as such Loan Party shall reasonably request to evidence such
termination.

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

         Section 11.19     Co-Borrower's Obligations. The Co-Borrower is a party
hereto for purposes of providing co-extensive obligors (on a joint and several
basis) for the Obligations, although the parties acknowledge that the
Co-Borrower shall not have any substantial assets or 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.

         Section 11.20     Intercreditor Agreement. Each Lender (including each
assignee which becomes a Lender pursuant to Section 11.6) consents and agrees to
the provisions of the Intercreditor Agreement, including the indemnity
provisions set forth in Section 7 thereof. The Lenders also hereby authorize and

         Section 11.21     Certain Reorganization Transactions. Notwithstanding

enforceable, and first perfected security interest in the Collateral covered
thereby prior to the Reorganization Transactions that is affected by the
Reorganization Transactions (as the nature of such Collateral may change

Administrative Agent shall enter into such amendments to the Security Documents
or other instruments that are necessary or that may otherwise be advisable to
reflect the Reorganization Transactions and effect or continue such perfected
security interests in such Collateral.

                              THE COLLATERAL AGENT

         Section 12.1      Appointment. Each Lender hereby irrevocably
designates and appoints JPMorgan as the Collateral Agent of such Lender under
this Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes JPMorgan, as the Collateral Agent for such Lender, to take such
action on its behalf under the provisions of this Agreement and the other Loan
Documents and to exercise such powers and perform such duties as are expressly
delegated to the Collateral Agent by the terms of this Agreement and the other
Loan Documents, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere in this
Agreement, the Collateral Agent shall not have any duties or responsibilities,
except those expressly set forth herein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the Collateral Agent.

                                       84

<PAGE>

         Section 12.2      Delegation of Duties. The Collateral Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Collateral Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

         Section 12.3      Exculpatory Provisions. Neither the Collateral Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Collateral Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of the Borrower to perform its obligations hereunder
or thereunder. The Collateral Agent shall not be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

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

         Section 12.5      Notice of Default. The Collateral Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Collateral Agent has received notice from the
Administrative Agent, a Lender or the Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". The Collateral Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by the EPN
Group Administrative Agents acting jointly or the Required EPN Group Lenders;
provided that unless and until the

                                       85

<PAGE>

Collateral Agent shall have received such directions, the Collateral Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the EPN Group Lenders.

         Section 12.6      Indemnification. The Lenders agree to indemnify the
Collateral Agent in its capacity as such (to the extent not reimbursed by the
Borrower and without limiting the obligation of the Borrower to do so), ratably
according to their respective Total EPN Group Credit Percentages in effect on
the date on which indemnification is sought under this Section, from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever which
may at any time (including, without limitation, at any time following the
payment of the Loans) be imposed on, incurred by or asserted against the
Collateral Agent in any way relating to or arising out of this Agreement, any of
the other Loan Documents or any documents contemplated by or referred to herein
or therein or the transactions contemplated hereby or thereby or any action
taken or omitted by the Collateral Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Collateral
Agent's gross negligence or willful misconduct. The agreements in this Section
12.6 shall survive the payment of the Loans and all other amounts payable
hereunder.

         Section 12.7      Successor Collateral Agent. The Collateral Agent may
resign as Collateral Agent upon 10 days' written notice to the Lenders. If the
Collateral Agent shall resign as Collateral Agent under this Agreement and the
other Loan Documents, then the Required EPN Group Lenders shall appoint from
among the EPN Group Lenders a successor agent for the EPN Group Lenders, which
successor agent shall be approved by the Borrower, whereupon such successor
agent shall succeed to the rights, powers and duties of the Collateral Agent,
and the term "Collateral Agent" shall mean such successor agent effective upon
such appointment and approval, and the former Collateral Agent's rights, powers
and duties as Collateral Agent shall be terminated, without any other or further
act or deed on the part of such former Collateral Agent or any of the parties to
this Agreement. After any retiring Collateral Agent's resignation as Collateral
Agent, the provisions of this Section shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Collateral Agent under
this Agreement and the other Loan Documents.

         Section 12.8      Amendment. None of the terms or provisions of this
Article XII may be amended, modified or waived without the written consent of
the then Collateral Agent.

                  The Borrower is party to a sponsor agreement under the terms

                               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.

         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.

                  FOR VALUE RECEIVED, the undersigned, EL PASO ENERGY PARTNERS,
L.P., a Delaware limited partnership (the "Borrower") and EL PASO ENERGY
PARTNERS FINANCE CORPORATION, a Delaware corporation (the "Co-Borrower"), hereby
jointly and severally unconditionally promise to pay to the order of
[_______________] (the "Lender") at the office of JPMorgan Chase Bank located at
270 Park Avenue, New York, New York 10017, in lawful money of the United States
of America and in immediately available funds, the principal amount of
[________________] ($___________) on the Maturity Date (as defined in the Credit
Agreement identified below), such principal to be paid on the date and in the
amounts set forth in Section 2.2 of the Credit Agreement and on such other dates
and in such other amounts set forth in the Credit Agreement.

                  Each of the undersigned further agrees to pay interest in like
money at such office on the unpaid principal amount hereof from time to time
from the date hereof at the applicable rate per annum set forth in Section 4.4
of the Credit Agreement until any such amount shall become due and payable
(whether at the stated maturity, by acceleration or otherwise), and thereafter
on such overdue amount at the rate per annum set forth in subsection 4.4(c) of
said Credit Agreement until paid in full (both before and after judgment).
Interest shall be payable in arrears on each Interest Payment Date commencing on
the first such date to occur after the date hereof, provided that interest
accruing pursuant to subsection 4.4(c) of the Credit Agreement shall be payable
on demand. In no event shall the interest payable hereon, whether before or
after maturity, exceed the maximum interest which, under applicable law, may be
charged on this Note, and this Note is expressly made subject to the provisions
of the Credit Agreement which more fully set out the limitations on how interest
accrues hereon.

                  The holder of this Note is authorized to record the date, type
and amount of each Loan made by the Lender pursuant to Section 2.1 of said
Credit Agreement, each continuation thereof, each conversion of all or a portion
thereof to another type, the date and amount of each payment or prepayment of
principal with respect thereto, and, in the case of Eurodollar Loans, the length
of each Interest Period with respect thereto, on the schedules annexed hereto
and made a part hereof, or on a continuation thereof which shall be attached
hereto and made a part hereof, which recordation shall constitute prima facie
evidence of the accuracy of the information recorded in the absence of manifest
error; provided that failure by the Lender to make any such recordation on this
Note shall not affect the obligations of the Borrower under this Note or said
Credit Agreement.

                  This Note is one of the Notes referred to in the Senior
Secured Acquisition Term Loan Credit Agreement, dated as of November 27, 2002
(as amended, supplemented or otherwise modified from time to time, the "Credit

provided therein and is

subject to optional and mandatory prepayment in whole or in part as provided
therein. Terms used herein which are defined in the Credit Agreement shall have
such defined meanings unless otherwise defined herein or unless the context
otherwise requires.

Default specified in said Credit Agreement, all amounts then remaining unpaid on
this Note shall become, or may be declared to be, immediately due and payable
all as provided therein.

         any of the EPNHC Lenders) or otherwise, and (iii) the Marco Polo
         Clawback.

                  2. Guarantee. The Guarantor hereby unconditionally and
irrevocably guarantees to the EPN Group Administrative Agents, for the ratable
benefit of the EPN Group Lenders and the Marco Polo Lenders, the prompt and
complete payment and performance by each of the EPN Group Borrowers when due

<PAGE>

enforcing, or obtaining advice of counsel in respect of, any of their rights
under this Guarantee. 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 the EPN Group Borrowers 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 EPN Group Administrative Agents or any
of the EPN Group Lenders on account of its liability hereunder, it will notify
the EPN Group Administrative Agents and such EPN Group Lender in writing that
such payment is made under this Guarantee for such purpose. No payment or
payments made by the EPN Group Borrowers or any other Person or received or
collected by the EPN Group Administrative Agents or any of the EPN Group Lenders
from any of the EPN Group Borrowers 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. The EPN Group Administrative Agents and
each of the EPN Group Lenders are hereby irrevocably authorized at any time and
from time to time without notice to the Guarantor, any such notice being hereby
waived by the Guarantor, to set off and appropriate and apply any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the EPN Group Administrative Agents or
such EPN Group Lenders to or for the credit or the account of the Guarantor, or
any part thereof in such amounts as the EPN Group Administrative Agents or such
EPN Group Lenders may elect, on account of the liabilities of the Guarantor
hereunder and claims of every nature and description of the EPN Group
Administrative Agents or such EPN Group Lenders against the Guarantor, in any
currency, whether arising hereunder, under the Credit Agreement, any Note or
otherwise, as the EPN Group Administrative Agents or such EPN Group Lenders may
elect, whether or not the EPN Group Administrative Agents or such EPN Group
Lenders have made any demand for payment. The EPN Group Administrative Agents
and each of the EPN Group Lenders shall notify the Guarantor promptly of any
such set-off made by it and the application made by it of the proceeds thereof,
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of the EPN Group Administrative Agents
and each of the EPN Group Lenders under this paragraph are in addition to other
rights and remedies (including, without limitation, other rights of set-off)
which the EPN Group Administrative Agents or such EPN Group Lenders may have.

                  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 EPN Group Administrative Agents or any of the EPN Group
Lenders, the Guarantor shall not be entitled to be subrogated to any of the
rights of the EPN Group Administrative Agents or any of the EPN Group Lenders
against the EPN Group Borrowers or any other Loan Party or against any
collateral security or guarantee or right of offset held by the EPN Group
Administrative Agents

                                   Exhibit B-3

<PAGE>

or any of the EPN Group Lenders for the payment of the Obligations, nor shall
the Guarantor seek or be entitled to seek any contribution or reimbursement from
the EPN Group Borrowers or any other Loan Party in respect of payments made by
the Guarantor hereunder, until all amounts owing to the EPN Group Administrative
Agents and the EPN Group Lenders by the EPN Group Borrowers 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 the EPN Group Borrowers 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 EPN
Group Administrative Agents in the exact form received by the Guarantor (duly
indorsed by the Guarantor to the EPN Group Administrative Agents, if required),
to be applied against the Obligations, whether matured or unmatured, in such
order as the EPN Group Administrative Agents 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 EPN Group
Administrative Agents or any of the EPN Group Lenders may be rescinded by the
EPN Group Administrative Agents or such EPN Group 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 EPN Group Administrative Agents or any of the EPN
Group Lenders, and the 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 EPN
Group Lenders (or the Required 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 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. Neither the EPN Group Administrative Agents nor any of
the EPN Group 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 EPN Group Administrative
Agents or any of the EPN Group 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 is a party; and all dealings between the EPN
Group Borrowers or the Guarantor, on the one hand, and the EPN Group
Administrative Agents and the EPN Group 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.

                                   Exhibit B-4

<PAGE>

The Guarantor waives diligence, presentment, protest, demand for payment and
notice of default or nonpayment to or upon the EPN Group Borrowers or the
Guarantor with respect to the Obligations. This Guarantee shall be construed as
a continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity or enforceability of the Credit Agreement, any Note, any of the
other Loan Documents, any of the Obligations or any 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 the Guarantor) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of any of the EPN Group Borrowers for the Obligations, or of the
Guarantor under this Guarantee or under any other Loan Document, in bankruptcy
or in any other instance. When the EPN Group Administrative Agents are pursuing
their rights and remedies hereunder or any other Loan Document against the
Guarantor, the EPN Group Administrative Agents or any of the EPN Group Lenders
may, but shall be under no obligation to, pursue such rights and remedies as it
may have against the EPN Group Borrowers or any other Person or against any
collateral security or guarantee for the Obligations or any right of offset with
respect thereto, and any failure by the EPN Group Administrative Agents or any
of the EPN Group Lenders to pursue such other rights or remedies or to collect
any payments from the EPN Group Borrowers or any such other Person or to realize
upon any such collateral security or guarantee or to exercise any such right of
offset, or any release of the EPN Group Borrowers 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 EPN Group
Administrative Agents and the EPN Group 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 EPN Group Administrative Agents or any of the EPN
Group Lenders upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the EPN Group Borrowers or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the EPN Group Borrowers 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 EPN Group Administrative Agents without set-off or
counterclaim in U.S. Dollars at the office of the EPN Group Administrative
Agents located at One Chase Manhattan Plaza, 8th Floor, New York, New York
10081.

                  9. Representations, Warranties and Covenants. The Guarantor
represents and warrants to the EPN Group Administrative Agents and the EPN Group
Lenders, and agrees, that:

                  (c) each of the Loan Documents to which the Guarantor is a
         party constitutes a legal, valid and binding obligation of the

         Guarantor and will not result in or require the creation or imposition
         of any Lien on any of the properties or revenues of the Guarantor
         pursuant to any Requirement of Law or Contractual Obligation of the
         Guarantor;

                  (e) no consent or authorization of, filing with, or other act

         with the execution, delivery, performance, validity or enforceability
         of any of the Loan Documents to which the Guarantor is a party;

                  (f) no litigation, investigation or proceeding of or before
         any arbitrator or Governmental Authority is pending or, to the
         knowledge of the Guarantor, threatened by or against the Guarantor or
         against any of its properties or revenues (i) with respect to any of
         the Loan Documents to which the Guarantor is a party or any of the
         transactions contemplated thereby, (ii) which could have a material
         adverse effect on the business, operations, property or financial or
         other condition of the Guarantor or (iii) which could have a Material
         Adverse Effect;

                  (g) the Guarantor owns no material property other than the
         General Partnership Interest, the Common Units owned by it, its limited

         reserves have been provided on its books);

                                   Exhibit B-6

<PAGE>

                  (i) the representations and warranties contained in
         subsections 5.1 and 5.21 of the Credit Agreement are true and correct,
         and are incorporated herein by reference as if set forth here in full;
         and

                  (j) the Guarantor shall not take or cause to occur any action,
         or agree or consent to the taking or causing to occur of any action,

         of the Credit Agreement.

                  10. 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.

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 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 hereunder on any
one occasion shall not be construed as a bar to any right or remedy which the
EPN Group Administrative Agents 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.

                  13. Waivers and Amendments; Successors and Assigns; Governing
Law. None of the terms or provisions of this Guarantee may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
the Guarantor and the EPN Group Administrative Agents, provided that any
provision of this Guarantee may be waived by the EPN Group Administrative Agents
in a letter or agreement executed by the EPN Group Administrative Agents or by
facsimile transmission from the EPN Group Administrative Agents. This Guarantee
shall be binding upon the successors and assigns of the Guarantor and shall
inure to the benefit of the EPN Group Administrative Agents and the EPN Group
Lenders and their successors and assigns. This Guarantee shall be governed by,
and construed and interpreted in accordance with, the laws of the State of New
York.

         "Obligations": all obligations, liabilities and indebtedness of the

         2. Grant of Security Interest. As collateral security for the prompt
and complete payment and performance when due (whether at the stated maturity,
by acceleration or otherwise) of the Obligations, the Grantor hereby grants to
the Collateral Agent for the ratable benefit of the EPN Group Lenders and the
Marco Polo Lenders a security interest in all right, title and interest of the
Grantor in, to and under the G&A Agreement, whether now owned by the Grantor or

interest, and, to the extent not otherwise included, all Supporting Obligations
that support the payment or performance of the G&A Agreement, and all Proceeds
and products of the foregoing (collectively, the "Collateral").

         3. Rights of Collateral Agent and EPN Group Lenders; Limitations on
Collateral Agent's and EPN Group Lenders' Obligations.

         (a) Grantor Remains Liable under G&A Agreement. Anything herein to the
contrary notwithstanding, the Grantor shall remain liable under the G&A
Agreement to observe and perform all the conditions and obligations to be
observed and performed by it thereunder. Neither the Collateral Agent nor any of
the EPN Group Lenders shall have any obligation or liability under the G&A
Agreement by reason of or arising out of this Security Agreement, nor shall the
Collateral Agent or any of the EPN Group Lenders be obligated in any manner to
perform any of the obligations of the Grantor under or pursuant to the G&A
Agreement.

                                   Exhibit C-2

<PAGE>

         (b) Notice to Contracting Parties. Upon the request of the Collateral
Agent at any time after the occurrence and during the continuance of an Event of
Default, the Grantor shall notify parties to the G&A Agreement that the G&A
Agreement has been assigned to the Collateral Agent for the ratable benefit of
the EPN Group Lenders and the Marco Polo Lenders and that payments in respect
thereof shall be made directly to the Collateral Agent. The Collateral Agent may
in its own name or in the name of others communicate with parties to the G&A
Agreement to verify with them to its satisfaction the existence, amount and
terms of the G&A Agreement.

         4. Representations and Warranties. The Grantor hereby represents and
warrants that:

         (a) Title; No Other Liens. Except for the Lien granted to the
Collateral Agent for the ratable benefit of the EPN Group Lenders and the Marco
Polo Lenders pursuant to this Security Agreement, the Grantor owns each item of
the Collateral free and clear of any and all Liens or claims of others. No
security agreement, financing statement or other public notice with respect to
all or any part of the Collateral is on file or of record in any public office,
except such as may have been filed in favor of the Collateral Agent, for the
ratable benefit of the EPN Group Lenders and the Marco Polo Lenders, pursuant to
this Security Agreement.

         (b) Perfected First Priority Liens. The Liens granted pursuant to this
Security Agreement constitute perfected Liens on the Collateral in favor of the
Collateral Agent, for the ratable benefit of the EPN Group Lenders and the Marco
Polo Lenders, which are (except for any Liens on the Collateral which are
permitted to exist pursuant to the Credit Agreement or the EPNHC Credit
Agreement) prior to all other Liens on the Collateral created by the Grantor and
in existence on the date hereof and which are enforceable as such against all
creditors of and purchasers from the Grantor. All action necessary or desirable
to perfect such security interest in the Collateral requested by the Collateral
Agent, including the filing of financing statements, has been or will be duly
taken.

         (c) G&A Agreement. No consent of any party (other than the Grantor) to
the G&A Agreement is required, or purports to be required, in connection with
the execution, delivery and performance of this Security Agreement. The G&A
Agreement is in full force and effect and constitutes a valid and legally
enforceable obligation of the parties thereto, except as enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditor's rights generally. No consent or
authorization of, filing with or other act by or in respect of any Governmental
Authority is required in connection with the execution, delivery, performance,
validity or enforceability of the G&A Agreement by any party thereto other than
those which have been duly obtained, made or performed, are in full force and
effect and do not subject the scope of the G&A Agreement to any material adverse
limitation, either specific or general in nature. Neither the Grantor nor (to
the best of the Grantor's knowledge) any other party to the G&A Agreement is in
default or is likely to become in default in the performance or observance of
any of the terms thereof. The Grantor has fully performed all its obligations
under the G&A Agreement. The right, title and interest of the Grantor in, to and
under the G&A Agreement are not subject to any defense, offset, counterclaim or
claim which would materially adversely affect the value of such G&A Agreement as
Collateral, nor have any of the foregoing been asserted or alleged against the
Grantor as to the G&A Agreement. The Grantor has delivered to the Collateral
Agent and each of the EPN Group

                                   Exhibit C-3

         (h) Enforceability. This Security Agreement constitutes a legal, valid
and binding obligation of the Grantor enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally.

         (i) No Conflict. The execution, delivery and performance of this
Security Agreement will not violate any provision of any Requirement of Law or
Contractual Obligation of the Grantor and will not result in the creation or
imposition of any Lien on any of the properties or revenues of the Grantor
pursuant to any Requirement of Law or Contractual Obligation of the Grantor,
except as contemplated hereby.

         (j) No Consents, etc. No consent or authorization of, filing with, or

<PAGE>

         (a) Further Documentation; Pledge of Instruments and Chattel Paper. At
any time and from time to time, upon the written request of the Collateral
Agent, and at the sole expense of the Grantor, the Grantor will promptly and
duly execute and deliver such further instruments and documents and take such
further action as the Collateral Agent may reasonably request for the purpose of
obtaining or preserving the full benefits of this Security Agreement and of the
rights and powers herein granted, including, without limitation, the filing of
any financing or continuation statements under the Uniform Commercial Code in

hereby authorizes the Collateral Agent, its counsel or its representative, at
any time and from time to time, to file financing statements and amendments to
financing statements that describe the Collateral, in such jurisdictions as the
Collateral Agent may deem necessary or desirable in order to perfect or maintain
the perfection of the security interests granted by the Grantor under this
Security Agreement. The Grantor 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. A
carbon, photographic or other reproduction of this Security Agreement shall be
sufficient as a financing statement for filing in any jurisdiction. If any
amount payable under or in connection with any of the Collateral shall be or
become evidenced by any Instrument or Chattel Paper, such Instrument or Chattel
Paper shall be immediately delivered to the Collateral Agent, duly endorsed in a
manner satisfactory to the Collateral Agent, to be held as Collateral pursuant
to this Security Agreement.

         (b) Indemnification. The Grantor agrees to pay, and to save the
Collateral Agent and the EPN Group Lenders harmless from, any and all
liabilities, and reasonable costs and expenses (including, without limitation,
legal fees and expenses), (i) with respect to, or resulting from, any delay in
paying, any and all excise, sales or other taxes which may be payable or
determined to be payable with respect to any of the Collateral, (ii) with
respect to, or resulting from, any delay in complying with any Requirement of
Law applicable to any of the Collateral or (iii) in connection with any of the
transactions contemplated by this Security Agreement. In any suit, proceeding or
action brought by the Collateral Agent or any of the EPN Group Lenders under the
G&A Agreement for any sum owing thereunder, or to enforce any provisions of the
G&A Agreement, the Grantor will save, indemnify and keep the Collateral Agent
and such EPN Group Lender harmless from and against all reasonable expense, loss
or damage suffered by reason of any defense, setoff, counterclaim, recoupment or
reduction or liability whatsoever of the account debtor or obligor thereunder,
arising out of a breach by the Grantor of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to or in
favor of such account debtor or obligor or its successors from the Grantor.

         (c) Maintenance of Records. The Grantor will keep and maintain at its
own cost and expense satisfactory and complete records of the Collateral,
including, without limitation, a record of all payments received and all credits
granted with respect to the G&A Agreement. The Grantor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby. For the Collateral Agent's and the EPN Group
Lenders' further security, the Collateral Agent, for the ratable benefit of the
EPN Group Lenders and the Marco Polo Lenders, shall have a security interest in
all of the Grantor's books and records pertaining to the Collateral, and the
Grantor shall turn over any such books and records to the Collateral Agent or to
its representatives during normal business hours at the request of the
Collateral Agent.

<PAGE>

         (d) Right of Inspection. The Collateral Agent and the EPN Group Lenders
shall at all times have full and free access during normal business hours to all
the books, correspondence and records of the Grantor, and the Collateral Agent
and the EPN Group Lenders and their respective representatives may examine the
same, take extracts therefrom and make photocopies thereof, and the Grantor
agrees to render to the Collateral Agent and the EPN Group Lenders, at the
Grantor's cost and expense, such clerical and other assistance as may be
reasonably requested with regard thereto.

         (e) Compliance with Laws, etc. The Grantor will comply in all material
respects with all Requirements of Law applicable to the Collateral or any part
thereof or to the operation of the Grantor's business; provided, however, that
the Grantor may contest any Requirement of Law in any reasonable manner which
shall not, in the sole opinion of the Collateral Agent, adversely affect the
Collateral Agent's or the EPN Group Lenders' rights or the priority of their
Liens on the Collateral.

         (f) Compliance with Terms of G&A Agreement. The Grantor will perform
and comply in all material respects with all its obligations under the G&A
Agreement and all its other Contractual Obligations relating to the Collateral.

         (g) Payment of Obligations. The Grantor will pay promptly when due all
taxes, assessments and governmental charges or levies imposed upon the
Collateral or in respect of its income or profits therefrom, as well as all
claims of any kind (including, without limitation, claims for labor, materials
and supplies) against or with respect to the Collateral, except that no such
charge need be paid if (i) the validity thereof is being contested in good faith
by appropriate proceedings, (ii) such proceedings do not involve any material
danger of the sale, forfeiture or loss of any of the Collateral or any interest
therein and (iii) such charge is adequately reserved against on the Grantor's
books in accordance with GAAP.

         (h) Limitation on Liens on Collateral. The Grantor will not create,
incur or permit to exist, will defend the Collateral against, and will take such
other action as is necessary to remove, any Lien or claim on or to the
Collateral, other than the Liens created hereby and will defend the right, title
and interest of the Collateral Agent and the EPN Group Lenders in and to any of
the Collateral against the claims and demands of all Persons whomsoever.

         (i) Limitations on Dispositions of Collateral. The Collateral Agent and
the EPN Group Lenders do not authorize, and the Grantor agrees, not sell,
transfer, lease or otherwise dispose of any of the Collateral, or attempt, offer
or contract to do so except in the ordinary course of its business.

         (j) Limitations on Modifications, Waivers, Extensions of the G&A
Agreement. The Grantor will not (i) amend, modify, terminate or waive any
provision of the G&A Agreement in any manner which could reasonably be expected
to materially adversely affect the value of such Management Contract as
Collateral, (ii) fail to exercise promptly and diligently each and every
material right which it may have under such G&A Agreement or (iii) fail to
deliver to the Collateral Agent a copy of each material demand, notice or
document received by it relating in any way to the G&A Agreement.

                                   Exhibit C-6

<PAGE>

         (k) Limitations on Discounts, Compromises, Extensions. Other than in
the ordinary course of business as generally conducted by the Grantor over a
period of time, the Grantor will not grant any extension of the time of payment
on or performance under the G&A Agreement, compromise, compound or settle the
same for less than the full amount thereof, release, wholly or partially, any
Person liable for the payment or performance thereof, or allow any credit or
discount whatsoever thereon.

         (l) Notices. The Grantor will advise the Collateral Agent and the EPN
Group Lenders promptly, in reasonable detail, at their respective addresses set
forth in the Credit Agreement, (i) of any Lien (other than Liens created hereby
or permitted under the Credit Agreement or the EPNHC Credit Agreement) on, or
claim asserted against, any of the Collateral and (ii) of the occurrence of any
other event which could reasonably be expected to have a material adverse effect
on the aggregate value of the Collateral or on the Liens created hereunder.

         (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

<PAGE>

         (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

<PAGE>

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

<PAGE>

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

<PAGE>

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.

                                  Exhibit C-11

         IN WITNESS WHEREOF, the Grantor has caused this Security Agreement to
be duly executed and delivered as of the date first above written.

                                    GUARANTEE

         GUARANTEE, dated as of October 10, 2002 (as amended, supplemented or
otherwise modified from time to time, the "Guarantee"), made by EL PASO ENERGY
PARTNERS, L.P., a Delaware limited partnership, and EL PASO ENERGY PARTNERS
FINANCE CORPORATION, a Delaware corporation (together with El Paso Energy
Partners, L.P., each a "Guarantor"), in favor of JPMORGAN CHASE BANK, as
administrative agent (in such capacity, the "EPNHC Administrative Agent") for
the banks and other financial institutions (the "EPNHC Lenders") parties to the
Amended and Restated Credit Agreement, dated as of April 8, 2002 and as amended
and restated as of October 10, 2002 (as amended, supplemented or otherwise
modified from time to time, the "EPNHC Credit Agreement") among EPN Holding
Company, L.P., a Delaware limited partnership ("EPNHC"), the EPNHC Lenders and
the EPNHC Administrative Agent.

                              W I T N E S S E T H :

         WHEREAS, pursuant to the EPNHC Credit Agreement, the EPNHC Lenders have
severally agreed to make Loans to EPNHC upon the terms and subject to the
conditions set forth therein; it is a condition precedent to the obligation of
the EPNHC Lenders to make their respective loans to EPNHC under the EPNHC Credit
Agreement that the Guarantor shall have executed this Guarantee for the benefit
of the EPNHC Administrative Agent and the EPNHC Lenders;

         NOW, THEREFORE, in consideration of the premises and to induce the
EPNHC Administrative Agent and the EPNHC Lenders to enter into the EPNHC Credit
Agreement and to induce the EPNHC Lenders to make their respective Loans to
EPNHC under the EPNHC Credit Agreement, the Guarantor hereby agrees with the
EPNHC Administrative Agent, for the ratable benefit of the EPNHC Lenders, as
follows:

         1.       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

<PAGE>

Administrative Agent or the EPNHC Lenders that are required to be paid by EPNHC
pursuant to the terms of the EPNHC Credit Agreement) or otherwise.

         2.       Guarantee. 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. The Guarantor further agrees to pay any and all expenses
(including, without limitation, all fees and disbursements of counsel) which may
be paid or incurred by the EPNHC Administrative Agent or by the EPNHC Lenders in
enforcing, or obtaining advice of counsel in respect of, any of their rights
under this Guarantee. 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. The EPNHC Administrative Agent and each of
the EPNHC Lenders are hereby irrevocably authorized at any time and from time to
time without notice to the Guarantor, any such notice being hereby waived by the
Guarantor, to set off and appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), in any currency, and any other
credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by the EPNHC Administrative Agent or such EPNHC Lenders to or for the
credit or the account of the Guarantor, or any part thereof in such amounts as
the EPNHC Administrative Agent or such EPNHC Lenders may elect, on account of
the liabilities of the Guarantor hereunder and claims of every nature and
description of the EPNHC Administrative Agent or such EPNHC Lenders against the
Guarantor, in any currency, whether arising hereunder, under the EPNHC Credit
Agreement, any Note or otherwise, as the EPNHC Administrative Agent or such
EPNHC Lenders may elect, whether or not the EPNHC Administrative Agent or such
EPNHC Lenders has made any demand for payment. The EPNHC Administrative Agent
and each of the EPNHC Lenders shall notify the Guarantor promptly of any such
set-off made by it and the application made by it of the proceeds thereof,
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of the EPNHC Administrative Agent and
each of the EPNHC Lenders under this paragraph are in addition to other rights
and remedies (including, without limitation, other rights of set-off) which the
EPNHC Administrative Agent or such EPNHC Lenders may have.

                                   Exhibit D-2

<PAGE>

         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

<PAGE>

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. This Guarantee shall be construed as a continuing,
absolute and unconditional guarantee of payment without regard to (a) the

represents and warrants that:

                  (a)      the Pledgor has the power and authority and the legal
         right to execute and deliver, to perform its obligations under, and to
         grant the Lien on the Collateral pursuant to, this Agreement and has
         taken all necessary action to authorize its execution, delivery and
         performance of, and grant of the Lien on the Collateral pursuant to,
         this Agreement;

                  (b)      this Agreement constitutes a legal, valid and binding
         obligation of the Pledgor enforceable against the Pledgor in accordance
         with its terms, except as enforceability may be limited by bankruptcy,
         insolvency, reorganization, moratorium or similar laws affecting the
         enforcement of creditors' rights generally and by general equitable
         principles;

                  (c)      the execution, delivery and performance of this
         Agreement will not violate any provision of any Requirement of Law or
         Contractual Obligation of the Pledgor and will not result in the
         creation or imposition of any Lien on any of the properties or revenues
         of the Pledgor pursuant to any Requirement of Law or Contractual
         Obligation of the Pledgor, except as contemplated hereby;

                  (d)      no consent or authorization of, filing with, or other
         act by or in respect of, any arbitrator or Governmental Authority and
         no consent of any other Person (including, without limitation, any
         creditor of the Pledgor or any of the Subsidiaries), is required in
         connection with the execution, delivery, performance, validity or
         enforceability of this Agreement;

                  (e)      no litigation, investigation or proceeding of or
         before any arbitrator or Governmental Authority is pending or, to the
         knowledge of the Pledgor, threatened by or against the Pledgor or
         against any of the Collateral with respect to this Agreement or any of
         the transactions contemplated hereby;

                  (f)      the Pledgor is the record and beneficial owner of,
         and has good and legal title to, the Interests and the Pledged Stock,
         free of any and all Liens or options in favor

                                   Exhibit E-5

<PAGE>

         of, or claims of, any other Person, except the Liens created by this
         Agreement, and (i) all the Pledged Certificates have been duly and
         validly issued and (ii) all the shares of Pledged Stock have been duly
         and validly issued and are fully paid and nonassessable;

                  (g)      no security agreement, financing statement,
         equivalent security or lien instrument or continuation statement
         covering all or part of the Collateral is on file or of record in any
         public office, except such as may have been or will be filed in favor
         of the Collateral Agent pursuant to this Agreement or must have
         otherwise been filed in favor of the Collateral Agent;

                  (h)      upon delivery to the Collateral Agent of the Pledged
         Certificates and the stock certificates evidencing the Pledged Stock
         and upon the filing of the financing statements described on Schedule
         II to this Agreement, the Lien granted pursuant to this Agreement will
         constitute a valid, perfected first priority Lien on the Collateral,
         prior to all other Liens, which will be enforceable as such as against
         all creditors of the Pledgor and any Persons purporting to purchase any
         Collateral from the Pledgor, except as enforceability may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or
         similar laws affecting the enforcement of creditors' rights generally.
         All action necessary or desirable to perfect such security interest in
         each item of the Collateral requested by the Collateral Agent,
         including the filing of financing statements in the offices referred to
         on Schedule II to this Agreement has been or will be duly taken;

                  (i)      the name of the Borrower as indicated on the public
         record of the Borrower's jurisdiction of organization, which shows the
         Borrower to have been organized, is "El Paso Energy Partners, L.P.".
         The Borrower's mailing address is Four Greenway Plaza, Houston, Texas
         77046. The Borrower is a Delaware limited partnership, and the
         Borrower's organizational identification number in the State of
         Delaware is 2317845. The Borrower was formerly known as "Leviathan Gas
         Pipeline Partners, L.P." Other than this name, the Borrower has not
         used any other name or trade name. The Pledgor recognizes that
         financing statements pertaining to the Collateral have been or may be
         filed where the Pledgor maintains any Collateral or is organized.
         Without limitation of any other covenant herein, the Pledgor will not
         cause or permit (i) any change to be made in its name, identity or
         corporate structure or (ii) any change to the Pledgor's jurisdiction of
         organization, unless the Pledgor shall have first (1) notified the
         Collateral Agent of such change at least thirty (30) days prior to the
         effective date of such change, and (2) taken all action reasonably
         requested by the Collateral Agent for the purpose of maintaining the
         perfection and priority of the Collateral Agent's security interests
         and rights under this Agreement. In any notice furnished pursuant to
         this subsection, the Pledgor will expressly state that the notice is
         required by this Agreement and contains facts that may require
         additional filings of financing statements or other notices for the
         purposes of continuing perfection of the Collateral Agent's security
         interest in the Collateral;

                  (j)      (i) each of the LLCs is a limited liability company
         duly formed and validly existing under the laws of the State of
         Delaware, (ii) each of the Partnerships is a general or limited
         partnership (as the case may be) duly formed and validly existing under
         the laws of the State of Delaware, (iii) the Co-Borrower is a
         corporation duly organized,

                                   Exhibit E-6

<PAGE>

         validly existing and in good standing under the laws of the State of
         Delaware, and (iii) each of the Subsidiaries has all the requisite
         power and authority to own and operate its properties, to lease the
         properties it operates and to carry on its business as now conducted
         and is duly qualified as a foreign limited liability company or a
         foreign corporation and in good standing in each jurisdiction in which
         the character of its properties owned or the nature of the activities
         conducted by it makes such qualification or licensing necessary, except
         where failure to be so qualified could not have a Material Adverse
         Effect. Except to the extent set forth on Schedule I(A) hereto, the
         Pledgor is the sole owner of each of the LLCs and Partnerships, and the
         nature of the Pledgor's interest in each of the LLCs and Partnerships
         is as set forth on Schedule I(A) hereto. The shares of Pledged Stock
         constitutes the Pledgor's percentage interest of all the issued and
         outstanding shares of all classes of the capital stock of each
         Corporation, as such percentage is set forth on Schedule I(B) hereto.
         The list of certificates set forth on (i) Schedule I(A) constitutes a
         full and complete list of all the certificates of limited liability
         company interests of the LLCs owned by the Pledgor and (ii) Schedule
         I(B) constitutes a full and complete list of all of the issued and
         outstanding shares of capital stock of any class of each corporate or
         other Subsidiary beneficially owned by the Pledgor on the date hereof
         (whether or not registered in the name of the Pledgor) and said
         Schedule I(B) correctly identifies, as at the date hereof, the
         respective class and par value of the shares comprising such Pledged
         Stock and the respective number of shares (and registered owners
         thereof) represented by each such certificate. Complete and correct
         copies of the Governing Documents of each Subsidiary have been
         delivered to the Collateral Agent. Transactions permitted by
         subsections 8.5, 8.6 and 11.22 of the Credit Agreement shall be
         permitted notwithstanding anything to the contrary in this subsection
         4(j); and

                  (k)      the execution and delivery of this Agreement will not
         result in any violation of or be in conflict with or constitute a
         default under any term of the Governing Documents of any Subsidiary, or
         to the best knowledge of the Pledgor, of any agreement or instrument of
         or judgment, decree, order, statute, rule or governmental regulation
         applicable to the Pledgor, or result in the creation of any Lien upon
         any of the properties or assets of the Pledgor (including, without
         limitation, the Collateral) pursuant to any such term other than the
         Lien in favor of the Collateral Agent created pursuant to this
         Agreement.

                  5.       Covenants. The 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 the 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, the 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 the Pledgor to the Collateral Agent, if required,

                                   Exhibit E-7

<PAGE>

         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. Any sums paid upon
         or in respect of the Pledged Stock upon the liquidation or dissolution
         of any corporate or other Subsidiary, such payments shall be paid over
         to the Collateral Agent to be held by it hereunder as additional
         collateral security for the Obligations, and in case any distribution
         of capital shall be made on or in respect of the Collateral or any
         property shall be distributed upon or with respect to the Collateral
         pursuant to the recapitalization or reclassification of the capital of
         any of the Subsidiaries, or pursuant to 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 the
         Pledgor, the Pledgor shall, until such money or property is paid or
         delivered to the Collateral Agent, hold such money or property in trust
         for the Collateral Agent, segregated from other funds of the Pledgor,
         as additional collateral security for the Obligations.

                  (b)      Except as permitted under the Credit Agreement or the
         EPNHC Credit Agreement, without the prior written consent of the
         Collateral Agent, the Pledgor will not (i) sell, assign, transfer,
         exchange or otherwise dispose of, or grant any option with respect to,
         the Collateral, (ii) create, incur or permit to exist any Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Agreement or (iii) vote to enable, or take any other action
         to permit, any corporate or other Subsidiary to issue any stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         stock or other equity securities of any nature of such Subsidiary. The
         Pledgor will defend the right, title and interest of the Collateral
         Agent in and to the Collateral against the claims and demands of all
         Persons whomsoever. The Pledgor 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
         Pledgor, the Pledgor will promptly and duly execute and deliver such
         further instruments and documents and take such further actions as the
         Collateral Agent may reasonably request for the purposes of obtaining
         or preserving the full benefits of this Agreement and of the rights and
         powers herein granted, including, without limitation, the filing of any
         financing or continuation statements under the Uniform Commercial Code
         in effect in any jurisdiction with respect to the Lien granted hereby.
         The Pledgor hereby authorizes the Collateral Agent, its counsel or its
         representative, at any time and from time to time, to file financing
         statements and amendments to financing statements that describe the
         Collateral, in such jurisdictions as the Collateral Agent may deem
         necessary or desirable in order to perfect or maintain the perfection
         of the security interests granted by the Pledgor under this Agreement.
         The Pledgor hereby further authorizes the Collateral Agent, its counsel
         or its representative, at any time and from time to time, to file
         continuation statements with respect to previously filed financing
         statements. If any amount payable under or in connection with any of
         the Collateral shall be or become evidenced by any promissory

                                   Exhibit E-8

<PAGE>

         note or other instrument, such note or instrument shall be immediately
         pledged hereunder to the Collateral Agent, duly endorsed in a manner
         satisfactory to the Collateral Agent.

                  (d)      The Pledgor will advise the Collateral Agent
         promptly, in reasonable detail, of any Lien or claim made or asserted
         against any of the Collateral.

                  (e)      The Pledgor agrees to pay, and to save the Collateral
         Agent harmless from, any and all liabilities with respect to, or
         resulting from any delay in paying, any and all stamp, excise, sales or
         other taxes which may be payable or determined to be payable with
         respect to any of the Collateral or in connection with any of the
         transactions contemplated by this Agreement.

                  (f)      Promptly, but in no case later than 30 days after the
         Pledgor forms or acquires a Subsidiary that is to be a Restricted
         Subsidiary, the 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 or Schedule II, as
         the case may be, to pledge its ownership interests in such Restricted
         Subsidiary to the Collateral Agent.

                  (g)      Cash Distributions; Cash Dividends; Voting Rights.
Unless an Event of Default shall have occurred and be continuing, the Pledgor
shall be permitted to receive (a) all cash distributions paid in the normal
course of business of the LLCs and to exercise all voting, member and manager
rights with respect to the Interests, and (b) all cash dividends paid in the
normal course of business of any corporate or other Subsidiary and consistent
with past practice, in respect of the Pledged Stock and to exercise all voting
and corporate rights with respect to the Pledged Stock; provided, however, that
no vote shall be cast or right exercised or other action taken which, in the
Collateral Agent's reasonable judgment, would impair the Collateral or which
would be inconsistent with or result in a breach of any provision of the 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 the Pledgor or the Collateral Agent of any right,
         privilege or option pertaining to such shares or certificates of or

                                   Exhibit E-9

<PAGE>

         evidencing the Interests or the Pledged Stock, and in connection
         therewith, the right to deposit and deliver any and all of the
         Interests or the Pledged Stock with any committee, depositary, transfer
         agent, registrar or other designated agency upon such terms and
         conditions as it may determine), all without liability except to
         account for property actually received by it, but the Collateral Agent
         shall have no duty to exercise any such right, privilege or option and
         shall not be responsible for any failure to do so or delay in so doing.

                  (b)      The rights of the Collateral Agent hereunder shall
         not be conditioned or contingent upon the pursuit by the Collateral
         Agent of any right or remedy against any Subsidiary, or against any
         other Person which may be or become liable in respect of all or any
         part of the Obligations or against any other collateral security
         therefor, guarantee thereof or right of offset with respect thereto.
         The Collateral Agent shall not be liable for any failure to demand,
         collect or realize upon all or any part of the Collateral or for any
         delay in doing so, nor shall it be under any obligation to sell or
         otherwise dispose of any Collateral upon the request of the Pledgor or
         any other Person or to take any other action whatsoever with regard to
         the Collateral or any part thereof.

                  8.       Collateral Agent's Appointment as Attorney-in-Fact.

                  (a)      The Pledgor hereby irrevocably constitutes and
         appoints the Collateral Agent and any officer or agent thereof, with
         full power of substitution, as its true and lawful attorney-in-fact
         with full irrevocable power and authority in the place and stead of the
         Pledgor and in the name of the Pledgor or in its own name, from time to
         time in the Collateral Agent's discretion, for the purpose of carrying
         out the terms of this Agreement, to take any and all appropriate action
         and to execute any and all documents and instruments which may be
         necessary or desirable to accomplish the purposes of this Agreement
         and, without limiting the generality of the foregoing, hereby gives the
         Collateral Agent the power and right, on behalf of the Pledgor without
         notice to or assent by the Pledgor to do the following:

                           (i)      upon the occurrence and continuation of an
                  Event of Default to ask, demand, collect, receive and give
                  acceptances and receipts for any and all moneys due and to
                  become due with respect to the Collateral and, in the name of
                  the Pledgor or its own name or otherwise, to take possession
                  of, endorse and collect any checks, drafts, notes, acceptances
                  or other instruments for the payment of moneys due with
                  respect to the Collateral and to file any claim or to take any
                  other action or proceeding in any court of law or equity or
                  otherwise as deemed appropriate by the Collateral Agent for
                  the purpose of collecting any and all such moneys due with
                  respect to the Collateral or whenever payable;

                           (ii)     to pay or discharge taxes, liens, security
                  interests or other encumbrances levied or placed on or
                  threatened against the Collateral; and

                           (iii)    upon the occurrence and during the
                  continuance of an Event of Default, (A) to direct any Person
                  liable for any payment to the Pledgor with respect to the
                  Collateral to make payment of any and all moneys due and to

                                  Exhibit E-10

<PAGE>

                  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

<PAGE>

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

<PAGE>

         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

<PAGE>

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

<PAGE>

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.

<PAGE>

                  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.

                  IN WITNESS WHEREOF, the undersigned has caused this Agreement
to be duly executed and delivered as of the date first above written.

                  reason of or arising out of this Security Agreement or the
                  receipt by the Collateral Agent or any such EPN Group Lenders
                  of any payment relating to such Account, Chattel Paper or

                  or under or pursuant to the G&A Agreement, to make any
                  payment, to make any inquiry as to the nature or the
                  sufficiency of any payment received by it or as to the
                  sufficiency of any performance by any party under any Account,
                  Chattel Paper or Payment Intangible (or any agreement giving
                  rise thereto) or under the G&A Agreement, to present or file

                           (b)      Notice to Account Debtors and Contracting
                  Parties. Upon the request of the Collateral Agent at any time

                  Polo Lenders and that payments in respect thereof shall be

                  Agent shall have the right to make test verifications of the
                  Accounts, Chattel Paper and Payment Intangibles in any manner
                  and through any medium that it reasonably considers advisable,
                  and the Borrower shall furnish all such assistance and
                  information as the Collateral Agent may require in connection
                  therewith. At any time and from time to time, upon the
                  Collateral Agent's request and at the expense of the Borrower,
                  the Borrower shall furnish to the Collateral Agent reports
                  showing reconciliations, aging and test verifications of, and
                  trial balances for, the Accounts, Chattel Paper and Payment

                  Agent hereby authorizes the Borrower to collect the Accounts,

                  Collateral Agent's direction and control, and the Collateral
                  Agent may curtail or terminate said authority at any time
                  after the occurrence and during the continuance of an Event of
                  Default. If required by the Collateral Agent at any time after

                  Intangibles, when collected by the Borrower, shall be

                  deposited by the Borrower in the exact form received, duly
                  indorsed by the Borrower to the Collateral Agent if required,
                  in a special collateral account maintained by the Collateral
                  Agent, subject to withdrawal by the Collateral Agent for the
                  ratable benefit of the EPN Group Lenders and the Marco Polo
                  Lenders only, as hereinafter provided, and, until so turned
                  over, 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. Each deposit of any such Proceeds shall
                  be accompanied by a report identifying in reasonable detail
                  the nature and source of the payments included in the deposit.
                  All Proceeds constituting collections of Accounts while held
                  by the Collateral Agent (or by the Borrower in trust for the
                  Collateral Agent for the ratable benefit of the EPN Group
                  Lenders and the Marco Polo Lenders) shall continue to be
                  collateral security for all of the Obligations and shall not
                  constitute payment thereof until applied as hereinafter
                  provided. At such intervals as may be agreed upon by the
                  Borrower and the Collateral Agent, or, if an Event of Default
                  shall have occurred and be continuing, at any time at the
                  Collateral Agent's election, the Collateral Agent shall apply
                  all or any part of the funds on deposit in said special
                  collateral account on account of the Obligations in such order
                  as the Collateral Agent may elect, and any part of such funds
                  which the Collateral Agent elects not so to apply and deems
                  not required as collateral security for the Obligations shall
                  be paid over from time to time by the Collateral Agent to the
                  Borrower or to whomsoever may be lawfully entitled to receive
                  the

                                  Exhibit F-6

<PAGE>

                  same. At the Collateral Agent's request, the Borrower shall
                  deliver to the Collateral Agent all original and other

                  transactions which gave rise to the Accounts, including,
                  without limitation, all original orders, invoices and shipping
                  receipts.

                  4.       Representations and Warranties. The Borrower hereby
         represents and warrants that:

                           (a)      Title; No Other Liens. Except for the Lien
                  granted to the Collateral Agent for the ratable benefit of the
                  EPN Group Lenders and the Marco Polo Lenders pursuant to this
                  Security Agreement and the other Liens permitted to exist on
                  the Collateral pursuant to the Credit Agreement or the EPNHC
                  Credit Agreement, the Borrower owns each item of the
                  Collateral free and clear of any and all Liens or claims of
                  others. No security agreement, financing statement or other
                  public notice with respect to all or any part of the
                  Collateral is on file or of record in any public office,
                  except such as may have been filed in favor of the Collateral
                  Agent, for the ratable benefit of the EPN Group Lenders and
                  the Marco Polo Lenders, pursuant to this Security Agreement or
                  as may be permitted pursuant to the Credit Agreement or the

                           (b)      Perfected First Priority Liens. The Liens
                  granted pursuant to this Security Agreement constitute
                  perfected Liens on the Collateral in favor of the Collateral
                  Agent, for the ratable benefit of the EPN Group Lenders and
                  the Marco Polo Lenders, which are (except for any Liens on the

                  against all creditors of and purchasers from the Borrower and
                  against any owner or purchaser of the real property where any
                  of the Equipment is located and any present or future creditor
                  obtaining a Lien on such real property. All actions necessary

                  or Chattel Paper which has not been delivered to the
                  Collateral Agent. The place where the Borrower keeps its
                  records concerning the Accounts, Chattel Paper and Payment

                  force and effect and constitutes a valid and legally
                  enforceable obligation of the parties thereto, except as
                  enforceability may be limited by bankruptcy, insolvency,
                  reorganization, moratorium or similar laws affecting the
                  enforcement of creditor's rights generally. No consent or
                  authorization of, filing with or other act by or in respect of
                  any Governmental Authority is required in connection with the
                  execution, delivery, performance, validity or enforceability
                  of the G&A Agreement by any party thereto other than those
                  which have been duly obtained, made or performed, are in full
                  force and effect and do not subject the scope of the G&A

                  no party to the G&A Agreement is in default or is likely to
                  become in default in the performance or observance of any of
                  the terms thereof. The right, title and interest of the
                  Borrower in, to and under the G&A Agreement are not subject to
                  any defense, offset, counterclaim or claim which would
                  materially adversely affect the value of the Collateral, nor
                  have any of the foregoing been asserted or alleged against the
                  Borrower as to the G&A Agreement. No amount payable to the
                  Borrower under or in connection with the G&A Agreement is
                  evidenced by any Instrument or Chattel Paper which has not
                  been delivered to the Collateral Agent.

                           (a)      Further Documentation; Pledge of Instruments
                  and Chattel Paper. At any time and from time to time, upon the
                  written request of the Collateral Agent, and at the sole
                  expense of the Borrower, the Borrower will promptly and duly
                  execute and deliver such further instruments and documents and
                  take such further action as the Collateral Agent may
                  reasonably request for the purpose of obtaining or preserving
                  the full benefits of this Security Agreement and of the rights
                  and powers herein granted, including, without limitation, the

                  financing statements and amendments to financing statements
                  that describe the collateral covered by such financing
                  statements as "all assets of the Borrower", "all personal
                  property of the Borrower", or words of similar effect, in such
                  jurisdictions as the Collateral Agent may deem necessary or
                  desirable in order to perfect or maintain the perfection of
                  the security interests granted by the Borrower under this
                  Security Agreement. The Borrower hereby further authorizes the

                  time and from time to time, to file continuation statements

                  photographic or other reproduction of this Security Agreement
                  shall be sufficient as a financing statement for filing in any
                  jurisdiction. If any amount payable under or in connection
                  with any of the Collateral shall be or become evidenced by any

                  all actions (other

                                  Exhibit F-9

<PAGE>

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

                           (b)      Indemnification. The Borrower agrees to pay
                  and to save the Collateral Agent and the EPN Group Lenders
                  harmless from any and all liabilities and reasonable costs and
                  expenses (including, without limitation, legal fees and
                  expenses), (i) with respect to, or resulting from, any delay
                  in paying, any and all excise, sales or other taxes which may
                  be payable or determined to be payable with respect to any of
                  the Collateral, (ii) with respect to, or resulting from, any
                  delay in complying with any Requirement of Law applicable to
                  any of the Collateral or (iii) in connection with any of the
                  transactions contemplated by this Security Agreement. In any
                  suit, proceeding or action brought by the Collateral Agent or
                  any of the EPN Group Lenders under any Account, Chattel Paper,
                  Payment Intangibles or G&A Agreement, for any sum owing
                  thereunder, or to enforce any provisions of any Account,
                  Chattel Paper, Payment Intangible or G&A Agreement, the
                  Borrower will save, indemnify and keep the Collateral Agent
                  and such EPN Group Lenders harmless from and against all
                  reasonable expense, loss or damage suffered by reason of any
                  defense, setoff, counterclaim, recoupment or reduction or
                  liability whatsoever of the Account Debtor or obligor
                  thereunder, arising out of a breach by the Borrower of any
                  obligation thereunder or arising out of any other agreement,
                  indebtedness or liability at any time owing to or in favor of
                  such Account Debtor or obligor or its successors from the
                  Borrower.

                           (c)      Maintenance of Records. The Borrower will
                  keep and maintain at its own cost and expense satisfactory and
                  complete records of the Collateral, including, without
                  limitation, a record of all payments received and all credits
                  granted with respect to the Accounts. For the Collateral
                  Agent's and the EPN Group Lenders' further security, the
                  Collateral Agent, for the ratable benefit of the EPN Group
                  Lenders and the Marco Polo Lenders, shall have a security
                  interest in all of the Borrower's books and records pertaining
                  to the Collateral, and the Borrower shall turn over any such
                  books and records to the Collateral Agent or to its
                  representatives during normal business hours at the request of
                  the Collateral Agent.

                  and make photocopies thereof, and the Borrower agrees to
                  render to the Collateral Agent and the EPN Group Lenders, at
                  the Borrower's cost and expense, such clerical and other
                  assistance as may be reasonably requested with regard thereto.
                  The Collateral Agent and the EPN Group Lenders and their
                  respective representatives shall at all times also have the
                  right to enter into and upon any premises where any of the
                  Inventory or Equipment is located for the purpose of
                  inspecting the same, observing its use or otherwise protecting
                  its interests therein.

                           (e)      Compliance with Laws, etc. The Borrower will
                  comply in all material respects with all Requirements of Law
                  applicable to the Collateral or any part thereof or to the
                  operation of the Borrower's business; provided, however, that
                  the Borrower may contest any Requirement of Law in any
                  reasonable manner which shall not, in the sole opinion of the
                  Collateral Agent, adversely affect the Collateral Agent's or
                  the EPN Group Lenders' rights or the priority of their Liens
                  on the Collateral.

                           (f)      Compliance with Terms of the G&A Agreement,

                  pay promptly when due all taxes, assessments and governmental
                  charges or levies imposed upon the Collateral or in respect of
                  its income or profits therefrom, as well as all claims of any
                  kind (including, without limitation, claims for labor,
                  materials and supplies) against or with respect to the
                  Collateral, except that no such charge need be paid if (i) the
                  validity thereof is being contested in good faith by
                  appropriate proceedings, (ii) such proceedings do not involve
                  any material danger of the sale, forfeiture or loss of any of
                  the Collateral or any interest therein and (iii) such charge
                  is adequately reserved against on the Borrower's books in
                  accordance with GAAP.

                           (h)      Limitation on Liens on Collateral. The
                  Borrower will not create, incur or permit to exist, will
                  defend the Collateral against, and will take such other action
                  as is necessary to remove, any Lien or claim on or to the
                  Collateral, other than the Liens created hereby and other than
                  as permitted pursuant to the Credit Agreement or the EPNHC
                  Credit Agreement, and will defend the right, title and
                  interest of the Collateral Agent and the EPN Group Lenders in
                  and to any of the Collateral against the claims and demands of
                  all Persons whomsoever.

                           (i)      Limitations on Dispositions of Collateral.
                  The Collateral Agent and the EPN Group Lenders do not
                  authorize, and the Borrower agrees not to sell, transfer,

                           (p)      Changes in Locations, Name, etc. The

                  any Collateral or (B) the Borrower's jurisdiction of
                  organization, unless the Borrower shall have first (1)

                  priority of the Collateral Agent's security interests under
                  this Security Agreement. In any notice furnished pursuant to
                  this subsection, the Borrower will expressly state that the
                  notice is required by this Security Agreement and contains
                  facts that may require additional filings of financing
                  statements or other notices for the purposes of continuing
                  perfection of the Collateral Agent's security interest in the
                  Collateral.

                           (q)      Patents and Trademarks.

                                    (i)      The Borrower (either itself or
                           through licensees) will, except with respect to any
                           Trademark that the Borrower 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

                           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

                           may become invalidated.

                           Patent may become abandoned or dedicated.

                           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

                                    (iv)     Whenever the Borrower, 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

                           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 the Borrower
                           relating thereto or represented thereby, and the

                           Commitments are terminated.

                                    (v)      The Borrower 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

                                    (vi)     In the event that any Patent or
                           Trademark included in the Collateral is infringed,
                           misappropriated or diluted by a third party, the
                           Borrower shall promptly notify the Collateral Agent
                           and the EPN Group Lenders after it learns thereof and
                           shall, unless the Borrower shall reasonably determine
                           that such Patent or Trademark is of negligible
                           economic value to the Borrower which determination
                           the Borrower 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 the Borrower shall reasonably deem
                           appropriate under the circumstances to protect such
                           Patent or Trademark.

                  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.

                           (s)      Commercial Tort Claims. If the Borrower
                  shall at any time hold or acquire a Commercial Tort Claim that
                  satisfies the requirements of the following sentence, then the
                  Borrower shall, within thirty (30) days after such Commercial
                  Tort Claim satisfies such requirements, notify the Collateral
                  Agent and the EPN Group Lenders in a writing signed by the
                  Borrower 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 Borrower in connection with such
                  Commercial Tort Claim shall exceed $5,000,000, and either (ii)
                  (A) the Borrower 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) the
                  Borrower 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 the Borrower is disclosed by
                  the Borrower 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 the Borrower, then, upon the request of the Collateral
                  Agent, the Borrower shall, within thirty (30) days after such
                  request is made, transmit to the Collateral Agent and the EPN
                  Group Lenders a writing signed by the Borrower 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. The Borrower hereby irrevocably
                  constitutes and appoints the Collateral Agent and any officer

                  and lawful attorney-in-fact with full irrevocable power and
                  authority in the place and stead of the Borrower and in the
                  name of the Borrower or in its own name, from time to time in
                  the Collateral Agent's discretion, for the purpose of carrying
                  out the terms of this Security Agreement, to take any and all
                  appropriate action and to execute any and all documents and
                  instruments which may be necessary or desirable to accomplish
                  the purposes of this Security Agreement, and, without limiting
                  the generality of the foregoing, the Borrower

                  hereby gives the Collateral Agent the power and right, on
                  behalf of the Borrower, without notice to or assent by the
                  Borrower, to do the following:

                                    (i)      in the case of any Account, Chattel
                           Paper or Payment Intangible, at any time when the
                           authority of the Borrower to collect the Accounts,
                           Chattel Paper or Payment Intangible has been
                           curtailed or terminated pursuant to the first
                           sentence of Section 3(d) hereof, or in the case of
                           any other Collateral, at any time when any Event of
                           Default shall have occurred and is continuing, in the
                           name of the Borrower or its own name, or otherwise,
                           to take possession of and indorse and collect any
                           checks, drafts, notes, acceptances or other
                           instruments for the payment of moneys due under any
                           Account, Instrument, General Intangible, Chattel
                           Paper, Payment Intangible or the G&A Agreement, 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, General Intangible or the G&A
                           Agreement 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;

                           express bills, bills of lading, storage or warehouse
                           receipts, drafts against debtors, assignments,

                           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 the Borrower with respect
                           to any Collateral; (F) to settle, compromise or
                           adjust any suit, action or proceeding described in
                           clause (E) above and, in connection therewith, to
                           give such discharges or releases as the Collateral

                           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

                                  Exhibit F-16

<PAGE>

                           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

<PAGE>

         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

<PAGE>

         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

<PAGE>

                  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.

EPN Credit Agreement are used herein as therein defined, and the following terms
shall have the following meanings:

                  "Adjusted Net Worth": of any Guarantor shall mean, as of any
         date of determination thereof, the excess of (i) the amount of the
         "present fair saleable value" of the assets of such Guarantor as of the
         date of such determination, over (ii) the amount of all "liabilities of
         such Guarantor, contingent or otherwise", as of the date of such
         determination, as such quoted terms are determined in accordance with
         applicable federal and state laws governing determinations of the
         insolvency of debtors.

                  "Commitments": (a) the "Revolving Loan Commitments" and "Term
         Loan Commitments" as defined in the EPN Credit Agreement and (b) the
         "Commitments" as defined in the EPNHC Credit Agreement.

                  "Determination Date": with respect to any Guarantor, the
         earlier of (a) the date of commencement of a case under Title 11 of the
         United States Code in which such

                                  Exhibit G-2

<PAGE>

         Guarantor is a debtor and (b) the date enforcement hereunder is sought
         with respect to such Guarantor.

                  "Extension of Credit": (i) all loans or advances made to the
         any of the EPN Group Borrowers under any Loan Document, (ii) all
         letters of credit issued for the account of any of the EPN Group
         Borrowers under any Loan Document, (iii) all bankers' acceptances
         created for the account of any of the EPN Group Borrowers under any
         Loan Document and (iv) all other extensions of credit to or for the
         benefit of any of the EPN Group Borrowers under any Loan Document.

                  "Loan Documents": (i) the "Loan Documents" under and as
         defined in the EPN Credit Agreement and (ii) the "Loan Documents" under
         and as defined in the EPNHC Credit Agreement.

                  "Maximum Guaranteed Amount": for any Guarantor, as of the
         Determination Date for such Guarantor, the sum of (i) an amount equal
         to the sum of each Extension of Credit (or portion thereof) the
         proceeds of which are used to make a Valuable Transfer (as defined
         below) to such Guarantor plus interest on such amount at the rate
         specified in the EPN Credit Agreement or the EPNHC Credit Agreement, as
         applicable, plus (ii) the greater of (I) ninety-five percent (95%) of
         the Adjusted Net Worth of such Guarantor at the date of the execution
         of this Guarantee before giving effect to any Extensions of Credit made
         on such date and (II) ninety-five percent (95%) of the Adjusted Net
         Worth of such Guarantor at the Determination Date for such Guarantor.
         For purposes hereof, the proceeds of an Extension of Credit (or portion
         thereof) are considered to be used to make a "Valuable Transfer" to a
         Guarantor if such proceeds are used to (i) make a loan, advance or
         capital contribution to such Guarantor, (ii) acquire from such
         Guarantor debt securities or other obligations of such Guarantor, (iii)

         Guarantor (but only to the extent of the economic benefit to such
         Guarantor of the interest so transferred), (iv) purchase equity
         securities of such Guarantor or (v) otherwise confer, directly or
         indirectly, an economic benefit on such Guarantor (but only to the
         extent of such benefit).

                  "Obligations": (i) 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 EPN or El Paso Finance, 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 EPN
         or El Paso Finance to the EPN Administrative Agent or the EPN Lenders,
         whether direct or indirect, absolute or contingent, due or to become
         due, now existing or hereafter incurred, which may arise under, out of,
         or in connection with, the EPN Credit Agreement, the other Loan
         Documents or any other document made, delivered or given in connection
         therewith, whether on account of principal, interest, reimbursement
         obligations, fees, indemnities, costs, expenses (including, without
         limitation, all fees and disbursements of counsel to the EPN
         Administrative Agent or any of the EPN Lenders) or otherwise, (ii) the

         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) and all other

         or the EPNHC Lenders, whether direct or indirect, absolute or
         contingent, due or to become due, now existing or hereafter incurred,
         which may arise under, out of, or in connection with, the EPNHC Credit
         Agreement, the other EPNHC Loan Documents or any other document made,
         delivered or given in connection therewith, whether on account of
         principal, interest, reimbursement obligations, fees, indemnities,
         costs, expenses (including, without limitation, all fees and
         disbursements of counsel to the EPNHC Administrative Agent or any of
         the EPNHC Lenders) or otherwise, and (iii) the Marco Polo Clawback.

         2.       Guarantee. (a) Each of the Guarantors hereby, jointly and
severally, unconditionally and irrevocably, guarantees to the EPN Group
Administrative Agents and the EPN Group Lenders and their respective successors,
indorsees, transferees and assigns, the prompt and complete payment by each of
the EPN Group Borrowers when due (whether at the stated maturity, by
acceleration or otherwise) of the Obligations of such EPN Group Borrower, and
each Guarantor further agrees to pay any and all expenses (including, without
limitation, all fees and disbursements of counsel) which may be paid or incurred
by the EPN Group Administrative Agents or any of the EPN Group Lenders in
enforcing, or obtaining advice of counsel in respect of, any rights with respect
to, or collecting, any or all of the Obligations and/or enforcing any rights
with respect to, or collecting against, such Guarantor under this Guarantee;
provided, however, that, anything herein or in any other Loan Document to the
contrary notwithstanding, the maximum liability of each Guarantor hereunder and
under the other Loan Documents shall in no event exceed such Guarantor's Maximum
Guaranteed Amount as determined at the Determination Date for such Guarantor;
and further provided, that the Maximum Guaranteed Amount for each Guarantor
hereunder shall in no event exceed the amount which can be guaranteed by such
Guarantor under applicable federal and state laws relating to the insolvency of
debtors.

                  (b)      Each Guarantor agrees that the Obligations may at any
time and from time to time exceed the Maximum Guaranteed Amount of such
Guarantor or of all of the Guarantors without impairing this Guarantee or
affecting the rights and remedies of the EPN Group Administrative Agents and the
EPN Group Lenders hereunder.

                  (c)      No payment or payments made by the EPN Group
Borrowers, any of the Guarantors, any other guarantor or any other Person or

guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment or payments other than payments made by
such Guarantor in respect of the Obligations or payments received or collected
from such Guarantor in respect of the Obligations, remain liable for the
Obligations up to its Maximum Guaranteed Amount until the Obligations are paid
in full and the Commitments are terminated.

                                  Exhibit G-4
<PAGE>

                  (d)      Each Guarantor agrees that whenever, at any time, or
from time to time, it shall make any payment to the EPN Group Administrative
Agents or any of the EPN Group Lenders on account of its liability hereunder, it
will notify the EPN Group Administrative Agents in writing that such payment is
made under this Guarantee for such purpose.

         3.       Right of Contribution. Each Guarantor hereby agrees that to
the extent that a Guarantor shall have paid more than its proportionate share of
any payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder who has not paid its
proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Paragraph 5 hereof. The
provisions of this Paragraph 3 shall in no respect limit the obligations and
liabilities of any Guarantor to the EPN Group Administrative Agents and the EPN
Group Lenders, and each Guarantor shall remain liable to the EPN Group
Administrative Agents and the EPN Group Lenders for the full amount guaranteed
by such Guarantor hereunder.

         4.       Right of Set-off. Each Guarantor hereby irrevocably authorizes
the EPN Group Administrative Agents and each of the EPN Group Lenders at any
time and from time to time without notice to such Guarantor or any other
Guarantor, any such notice being expressly waived by each Guarantor, to set-off
and appropriate and apply any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by the EPN Group Administrative Agents or such EPN Group Lender to or for
the credit or the account of such Guarantor, or any part thereof in such amounts
as the EPN Group Administrative Agents or such EPN Group Lenders may elect,
against and on account of the obligations and liabilities of such Guarantor to
the EPN Group Administrative Agents and the EPN Group Lenders hereunder and
claims of every nature and description of the EPN Group Administrative Agents
and the EPN Group Lenders against such Guarantor, in any currency, whether
arising hereunder, under the EPN Credit Agreement, the EPNHC Credit Agreement,
the Notes, the other Loan Documents or otherwise, as such EPN Group Lenders may
elect, whether or not the EPN Group Administrative Agents or any of the EPN
Group Lenders has made any demand for payment. Each of the EPN Group Lenders
agrees to notify such Guarantor promptly of any such set-off and the application
made by such EPN Group Lenders or the EPN Group Administrative Agents, as the
case may be, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each of the EPN Group
Lenders and the EPN Group Administrative Agents under this paragraph are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which such EPN Group Lenders may have.

         5.       No Subrogation. Notwithstanding any payment or payments made
by any of the Guarantors hereunder or under any other Loan Document or any
set-off or application of funds of any of the Guarantors by any of the EPN Group
Lenders or the EPN Group Administrative Agents, no Guarantor shall be entitled
to be subrogated to any of the rights of the EPN Group Administrative Agents or
any of the EPN Group Lenders against the EPN Group Borrowers or any other
Guarantor or any collateral security or guarantee or right of offset held by any
of the EPN Group Lenders or the EPN Group Administrative Agents for the payment
of the Obligations or any guarantee thereof, nor shall any Guarantor seek or be
entitled to seek any contribution or reimbursement from the EPN Group Borrowers
or any other Guarantor in respect

                                  Exhibit G-5

<PAGE>

of payments made by such Guarantor hereunder or under any other Loan Document,
until all amounts owing to the EPN Group Administrative Agents and the EPN Group
Lenders by the EPN Group Borrowers on account of the Obligations are paid in
full and the Commitments are terminated. If any amount shall be paid to any
Guarantor on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the EPN Group Administrative Agents and the EPN Group
Lenders, segregated from other funds of such Guarantor, and shall, forthwith
upon receipt by such Guarantor, be turned over to the EPN Group Administrative
Agents in the exact form received by such Guarantor (duly indorsed by such
Guarantor to the EPN Group Administrative Agents, if required), to be applied
against the Obligations, whether matured or unmatured, in such order as the EPN
Group Administrative Agents may determine.

         6.       Amendments, etc. with respect to the Obligations; Waiver of
Rights. Each Guarantor shall remain obligated hereunder and under the other Loan
Documents to which it is a party notwithstanding that, without any reservation
of rights against any Guarantor and without notice to or further assent by any
Guarantor, any demand for payment of any of the Obligations or any guarantees
thereof made by the 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. Neither the EPN Group Administrative Agents nor any of
the EPN Group Lenders shall have any obligation to protect, secure, perfect or
insure any Lien at any time held as security for the Obligations or any
guarantees thereof or for this Guarantee or any other Loan Document or any
property subject thereto. When making any demand hereunder or under any other
Loan Document against any of the Guarantors, the EPN Group Administrative Agents
or any of the EPN Group Lenders may, but shall be under no obligation to, make a
similar demand on the EPN Group Borrowers or any other Guarantor or guarantor,
and any failure by the EPN Group Administrative Agents or any of the EPN Group
Lenders to make any such demand or to collect any payments from the EPN Group
Borrowers or any such other Guarantor or guarantor or any release of the EPN
Group Borrowers or such other Guarantor or guarantor shall not relieve any of
the Guarantors in respect of which a demand or collection is not made or any of
the Guarantors not so released of their several obligations or liabilities
hereunder and under the other Loan Documents, and shall not impair or affect the
rights and remedies, express or implied, or as a matter of law, of the EPN Group
Administrative Agents or any of the EPN Group Lenders against any of the
Guarantors. For the purposes hereof "demand" shall include the commencement and
continuance of any legal proceedings.

<PAGE>

         7.       Guarantee Absolute and Unconditional. Each Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the EPN Group Administrative
Agents or any of the EPN Group Lenders upon this Guarantee or acceptance of this
Guarantee or any other Loan Document, the Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended, amended or waived, in reliance upon this Guarantee; and all dealings
between the EPN Group Borrowers or any of the Guarantors and the EPN Group
Administrative Agents or any of the EPN Group Lenders shall likewise be
conclusively presumed to have been had or consummated in reliance upon this
Guarantee and the other Loan Documents. Each Guarantor waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon 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. When pursuing its rights and
remedies hereunder against any Guarantor, the EPN Group Administrative Agents
and any of the EPN Group Lenders may, but shall be under no obligation to,
pursue such rights and remedies as it may have against the EPN Group Borrowers
or any other Person or against any collateral security or guarantee for the
Obligations or any right of offset with respect thereto, and any failure by the
EPN Group Administrative Agents or any of the EPN Group Lenders to pursue such
other rights or remedies or to collect any payments from the EPN Group Borrowers
or any such other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the EPN
Group Borrowers or any such other Person or any such collateral security,
guarantee or right of offset, shall not relieve such Guarantor of any liability
hereunder, and shall not impair or affect the rights and remedies, whether
express, implied or available as a matter of law, of the EPN Group
Administrative Agents or any of the EPN Group Lenders against such Guarantor.
This Guarantee shall remain in full force and effect and be binding in
accordance with and to the extent of its terms upon each Guarantor and the
successors and assigns thereof, and shall inure to the benefit of the EPN Group
Administrative Agents and the EPN Group Lenders, and their respective
successors, indorsees, transferees and assigns, until all the Obligations and
the obligations of each Guarantor under this Guarantee shall have been satisfied
by payment in full and the Commitments shall be terminated, notwithstanding that
from time to time during the term of the EPN Credit Agreement and the EPNHC
Credit Agreement the EPN Group Borrowers may be free from any Obligations.

         8.       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

<PAGE>

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

         10.      Representations and Warranties. Each Guarantor hereby
represents and warrants that:

                  (a)      such Guarantor is duly organized, validly existing
and, as applicable, in good standing under the laws of the jurisdiction of its
organization and has the power and authority and the legal right to own and
operate its property, to lease the property it operates and to conduct the
business in which it is currently engaged;

                  (b)      such Guarantor has the power and authority and the
legal right to execute and deliver, and to perform its obligations under, this
Guarantee, and has taken all necessary action to authorize its execution,
delivery and performance of this Guarantee;

                  (c)      this Guarantee constitutes a legal, valid and binding
obligation of such Guarantor enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforcement of creditors' rights
generally;

                  (d)      the execution, delivery and performance of this
Guarantee will not violate any provision of any Requirement of Law or
Contractual Obligation of such Guarantor and will not result in or require the
creation or imposition of any Lien on any of the properties or revenues of such
Guarantor pursuant to any Requirement of Law or Contractual Obligation of such
Guarantor;

                  (e)      no consent or authorization of, filing with, or other
act by or in respect of, any arbitrator or Governmental Authority and no consent
of any other Person (including, without limitation, any stockholder, member of,
owner of any limited liability company interest of or creditor of such
Guarantor) is required in connection with the execution, delivery, performance,
validity or enforceability of this Guarantee;

                  (f)      no litigation, investigation or proceeding of or
before any arbitrator or Governmental Authority is pending or, to the knowledge
of such Guarantor, threatened by or against such Guarantor or any of its
properties or revenues (i) with respect to this Guarantee or any of the
transactions contemplated hereby or (ii) which could have a material adverse
effect on the business, operations, property or financial or other condition of
such Guarantor;

                                  Exhibit G-8

<PAGE>

                  (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. 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.

         12.      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.

         13.      No Waiver; Cumulative Remedies. Neither the EPN Group
Administrative Agents nor any of the EPN Group Lenders shall by any act (except
by a written instrument pursuant to paragraph 14 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 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

<PAGE>

hereunder on any one occasion shall not be construed as a bar to any right or
remedy which the EPN Group Administrative Agents 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.

         14.      Integration; Waivers and Amendments; Successors and Assigns;
Governing Law. This Guarantee represents the agreement of each Guarantor with
respect to the subject matter hereof and there are no promises or
representations by the EPN Group Administrative Agents or any of the EPN Group
Lenders relative to the subject matter hereof not reflected herein. None of the
terms or provisions of this Guarantee may be waived, amended or supplemented or
otherwise modified except by a written instrument executed by each Guarantor and
the EPN Group Administrative Agents, provided that any provision of this
Guarantee may be waived by the EPN Group Administrative Agents and the EPN Group
Lenders in a letter or agreement executed by the EPN Group Administrative Agents
or by facsimile transmission from the EPN Group Administrative Agents. This
Guarantee shall be binding upon the successors and assigns of each Guarantor and
shall inure to the benefit of the EPN Group Administrative Agents and the EPN
Group Lenders and their respective successors and assigns. This Guarantee shall
be governed by and be construed and interpreted in accordance with the laws of
the State of New York.

         15.      Notices. All notices, requests and demands to or upon the
Guarantors or the EPN Group Administrative Agents or any of the EPN Group
Lenders to be effective shall be in writing (including by telecopy) and, unless
otherwise expressly provided herein, shall be deemed to have been duly given or
made when delivered by hand, or three days after deposit in the mail, postage
prepaid, or, in the case of telecopy notice, when received, addressed to a party
at the address provided for such party in subsection 11.2 of the EPN Credit
Agreement or subsection 11.2 of the EPNHC Credit Agreement or Schedule I hereto,
as the case may be.

         16.      Authority of EPN Group Administrative Agents. Each Guarantor
acknowledges that the rights and responsibilities of the EPN Group
Administrative Agents under this Guarantee with respect to any action taken by
the EPN Group Administrative Agents or the exercise or non-exercise by the EPN
Group Administrative Agents of any option, right, request, judgment or other
right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the EPN Group Administrative Agents and the EPN
Group Lenders, be governed by the EPN Credit Agreement and the EPNHC Credit
Agreement and by such other agreements with respect thereto as may exist from
time to time among them, but, as between the EPN Group Administrative Agents and
such Guarantor, the EPN Group Administrative Agents shall be conclusively
presumed to be acting as agent for the EPN Group Lenders with full and valid
authority so to act or refrain from acting, and no Guarantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

         17.      CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH GUARANTOR
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

                                  Exhibit G-10

<PAGE>

THIS AGREEMENT, SUCH GUARANTOR HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS
PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS. EACH GUARANTOR 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 GUARANTOR AT ITS ADDRESS SET FORTH IN SCHEDULE I HERETO.
NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE EPN GROUP ADMINISTRATIVE AGENTS 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 SUCH GUARANTOR IN ANY
OTHER JURISDICTION.

         18.      WAIVERS. (a) EACH GUARANTOR 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 EACH GUARANTOR AND THE EPN GROUP
ADMINISTRATIVE AGENTS 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.      Counterparts. This Guarantee may be executed by one or more of
the parties hereto on any number of separate counterparts and all of said
counterparts taken together shall be deemed to constitute one and the same
instrument.

represents and warrants that:

                  (a)      each Pledgor has the power and authority and the
         legal right to execute and deliver, to perform its obligations under,
         and to grant the Lien on the Collateral pursuant to, this Agreement and

         performance of, and grant of the Lien on the Collateral pursuant to,
         this Agreement;

                  (b)      this Agreement constitutes a legal, valid and binding
         obligation of each Pledgor enforceable against such Pledgor in
         accordance with its terms, except as enforceability may be limited by
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting the enforcement of creditors' rights generally and by general
         equitable principles;

                  (c)      the execution, delivery and performance of this
         Agreement will not violate any provision of any Requirement of Law or
         Contractual Obligation of any Pledgor and will not result in the
         creation or imposition of any Lien on any of the properties or revenues
         of any Pledgor pursuant to any Requirement of Law or Contractual
         Obligation of such Pledgor, except as contemplated hereby;

                  (d)      no consent or authorization of, filing with, or other
         act by or in respect of, any arbitrator or Governmental Authority and
         no consent of any other Person (including, without limitation, any
         creditor of any Pledgor or any of the Subsidiaries), is required in
         connection with the execution, delivery, performance, validity or
         enforceability of this Agreement;

                  (e)      no litigation, investigation or proceeding of or
         before any arbitrator or Governmental Authority is pending or, to the
         knowledge of any Pledgor, threatened by or against any Pledgor or
         against any of the Collateral with respect to this Agreement or any of
         the transactions contemplated hereby;

                  (f)      each Pledgor is the record and beneficial owner of,
         and has good and legal title to, the Interests and the Pledged Stock,
         free of any and all Liens or options in favor of, or claims of, any
         other Person, except the Liens created by this Agreement, and (i) all
         the Pledged Certificates have been duly and validly issued and (ii) all
         the shares of Pledged Stock have been duly and validly issued and are
         fully paid and nonassessable;

                  (g)      no security agreement, financing statement,
         equivalent security or lien instrument or continuation statement
         covering all or part of the Collateral is on file or of record in any
         public office, except such as may have been or will be filed in favor
         of the Collateral Agent pursuant to this Agreement or must have
         otherwise been filed in favor of the Collateral Agent;

                  (h)      upon delivery to the Collateral Agent of the Pledged
         Certificates and the stock certificates evidencing the Pledged Stock
         and upon the filing of the financing statements described on Schedule
         II to this Agreement, the Lien granted pursuant to this Agreement will
         constitute a valid, perfected first priority Lien on the Collateral,
         prior to

                                   Exhibit H-6

<PAGE>

         all other Liens, which will be enforceable as such as against all
         creditors of the Pledgors and any Persons purporting to purchase any
         Collateral from the Pledgors, except as enforceability may be limited
         by applicable bankruptcy, insolvency, reorganization, moratorium or
         similar laws affecting the enforcement of creditors' rights generally.
         All action necessary or desirable to perfect such security interest in
         each item of the Collateral requested by the Collateral Agent,
         including the filing of financing statements in the offices referred to
         on Schedule II to this Agreement has been or will be duly taken;

                  (i)      the name of each Pledgor as indicated on the public
         record of the Pledgors' jurisdiction of organization, which shows the
         Pledgor to have been organized, is as set forth on Schedule III hereto.
         The mailing address of each Pledgor is Four Greenway Plaza, Houston,
         Texas 77046. With respect to each Pledgor, the type of entity of such
         Pledgor and the organizational identification number in the State of
         Delaware for such Pledgor is correctly set forth on Schedule III
         hereto. To the extent indicated on Schedule III hereto, the Pledgors
         therein identified were formerly known by the names set forth on
         Schedule III hereto. Other than such names, no Pledgor has used any
         other name or trade name. The Pledgors recognize that financing
         statements pertaining to the Collateral have been or may be filed where
         the Pledgors maintain any Collateral or are organized. Without
         limitation of any other covenant herein, the Pledgors will not cause or
         permit (i) any change to be made in their names, identities or
         corporate structures or (ii) any changes to the Pledgors' jurisdictions
         of organization, unless the Pledgors shall have first (1) notified the
         Collateral Agent of such change at least thirty (30) days prior to the
         effective date of such change, and (2) taken all action reasonably
         requested by the Collateral Agent for the purpose of maintaining the
         perfection and priority of the Collateral Agent's security interests
         and rights under this Agreement. In any notice furnished pursuant to
         this subsection, each Pledgor will expressly state that the notice is
         required by this Agreement and contains facts that may require
         additional filings of financing statements or other notices for the
         purposes of continuing perfection of the Collateral Agent's security
         interest in the Collateral;

                  (j)      (i) each of the LLCs is a limited liability company
         duly formed and validly existing under the laws of the State of
         Delaware, (ii) each of the Partnerships is a general or limited
         partnership (as the case may be) duly formed and validly existing under
         the laws of the State of Delaware, except for Warwink Gathering and
         Treating, which is duly formed and validly existing under the laws of
         the State of Texas, (iii) each of the other Non-Corporate Subsidiaries
         is duly formed and validly existing under the laws of its jurisdiction
         of formation, (iv) each of the Corporations is duly organized and
         validly existing under the laws of the State of Delaware, and (v) each
         of the Subsidiaries has all the requisite power and authority to own
         and operate its properties, to lease the properties it operates and to
         carry on its business as now conducted and is duly qualified as a
         foreign limited liability company or a foreign corporation and in good
         standing in each jurisdiction in which the character of its properties
         owned or the nature of the activities conducted by it makes such
         qualification or licensing necessary, except where failure to be so
         qualified could not have a Material Adverse Effect. Except as set forth
         on Schedule I, each Pledgor is the sole owner (directly or through one
         or more wholly-owned Subsidiaries) of each of the relevant LLCs,
         Partnerships, and other Non-Corporate Subsidiaries, and the nature of
         each Pledgor's interest in each of the LLCs, Partnerships

                                   Exhibit H-7

<PAGE>

         and other Non-Corporate Subsidiaries is as set forth on Schedule I(A)
         hereto. The shares of Pledged Stock constitutes each Pledgor's
         percentage interest of all the issued and outstanding shares of all
         classes of the capital stock of each Corporation, as such percentage is
         set forth on Schedule I(B) hereto. The list of certificates set forth
         on (i) Schedule I(A) constitutes a full and complete list of all the
         certificates of limited liability company interests of the LLCs, the
         certificates of partnership interests of the Partnerships, and the
         certificates of equity interests of the other Non-Corporate
         Subsidiaries, in each case owned by each Pledgor, (ii) Schedule I(B)
         constitutes a full and complete list of all of the issued and
         outstanding shares of capital stock of any class of each corporate or
         other Subsidiary beneficially owned by each Pledgor on the date hereof
         (whether or not registered in the name of such Pledgor) and said
         Schedule I(B) correctly identifies, as at the date hereof, the
         respective class and par value of the shares comprising such Pledged
         Stock and the respective number of shares (and registered owners
         thereof) represented by each such certificate, and correct copies of
         the Governing Documents of each Subsidiary have been delivered to the
         Collateral Agent; and

                  (k)      the execution and delivery of this Agreement will not
         result in any violation of or be in conflict with or constitute a
         default under any term of the Governing Documents of any Subsidiary, or
         to the best knowledge of each Pledgor, of any agreement or instrument
         of or judgment, decree, order, statute, rule or governmental regulation
         applicable to such Pledgor, or result in the creation of any Lien upon
         any of the properties or assets of such Pledgor (including, without
         limitation, the Collateral) pursuant to any such term other than the
         Lien in favor of the Collateral Agent created pursuant to this
         Agreement.

                  5.       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. Any sums paid upon or in
         respect of the Pledged Stock upon the liquidation or dissolution of any
         corporate or other Subsidiary, such payments shall be paid over to the
         Collateral Agent to be held by it hereunder as additional collateral
         security for the Obligations, and in case any distribution of capital
         shall be made on or in respect of the Collateral or any property shall
         be distributed upon or with respect to the Collateral pursuant to the
         recapitalization or reclassification of the capital of any of the
         Subsidiaries, or pursuant to

                                   Exhibit H-8

<PAGE>

         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.

                  (b)      Except as permitted under the EPN Credit Agreement
         and the EPNHC Credit Agreement, without the prior written consent of
         the Collateral Agent, Pledgors will not (i) sell, assign, transfer,
         exchange or otherwise dispose of, or grant any option with respect to,
         the Collateral, (ii) create, incur or permit to exist any Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Agreement or (iii) vote to enable, or take any other action
         to permit, any corporate or other Subsidiary to issue any stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         stock or other equity securities of any nature of such Subsidiary. 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.

                  (d)      The Pledgors will advise the Collateral Agent
         promptly, in reasonable detail, of any Lien or claim made or asserted
         against any of the Collateral.

                  (e)      The Pledgors agree to pay, and to save the Collateral
         Agent harmless from, any and all liabilities with respect to, or
         resulting from any delay in paying, any and all stamp, excise, sales or
         other taxes which may be payable or determined to be payable

                                   Exhibit H-9

<PAGE>

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

                  (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

<PAGE>

                  (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

<PAGE>

                  (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

<PAGE>

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

<PAGE>

         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

<PAGE>

                  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. THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK.

                  17.      CONSENT TO JURISDICTION AND SERVICE OF PROCESS. EACH
PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT OR FOR RECOGNITION OR ENFORCEMENT OF
ANY JUDGMENT IN RESPECT THEREOF MAY BE BROUGHT AGAINST IT IN THE COURTS OF THE
STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT
OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PLEDGOR
HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND
UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH
PLEDGOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE
AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES
THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO EACH PLEDGOR AT THE
ADDRESS SET FORTH FOR EPN IN THE EPN CREDIT AGREEMENT. NOTHING HEREIN SHALL
AFFECT THE RIGHT OF THE COLLATERAL AGENT OR ANY HOLDER OF A NOTE TO SERVE
PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR
OTHERWISE PROCEED AGAINST ANY PLEDGOR IN ANY OTHER JURISDICTION.

                                  Exhibit H-15

<PAGE>

                  18.      WAIVERS.

                  (a)      EACH PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY
         WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF
         ANY ACTION DESCRIBED IN PARAGRAPH 17, OR THAT SUCH PROCEEDING WAS
         BROUGHT IN AN INCONVENIENT COURT, AND AGREES NOT TO PLEAD OR CLAIM THE
         SAME.

                  (b)      EACH OF THE PLEDGORS AND THE COLLATERAL AGENT HEREBY
         IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN
         ANY ACTION OR PROCEEDING OR COUNTERCLAIM OF ANY TYPE AS TO ANY MATTER
         ARISING DIRECTLY OR INDIRECTLY OUT OF OR WITH RESPECT TO THIS
         AGREEMENT.

                  19.      Notices. All notices, requests and demands to or upon
the Collateral Agent, the Pledgors or the Subsidiaries to be effective shall be
in writing (including by facsimile transmission), and, unless otherwise
expressly provided herein, shall be deemed to have been given or made when
actually delivered or, in the case of notice by facsimile transmission, when
received, addressed as set forth in the EPN Credit Agreement or the EPNHC Credit
Agreement, in the case of the Pledgors and the Collateral Agent, or as set forth
under such party's signature below, in the case of the Subsidiaries. The
Pledgors and the Subsidiaries may change their respective addresses and
transmission numbers by written notice to the Collateral Agent.

                  20.      Irrevocable Authorization and Instruction to
Subsidiaries. Each 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 any
Pledgor, and the Pledgors 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 each of the Pledgors and at the Pledgors' 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.

                  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 time or times.

                  (b)      Notice to Account Debtors. Upon the request of the
         Collateral Agent at any time after the occurrence and during the
         continuance of an Event of Default, each Grantor shall notify the
         Account Debtors that the applicable Accounts, Chattel Paper, and
         Payment Intangibles have been assigned to the Collateral Agent for the
         ratable benefit of the EPN Group Lenders and the Marco Polo Lenders and

         such assistance and information as the Collateral Agent may require in
         connection therewith. At any time and from time to time, upon the
         Collateral Agent's request and at the expense of each Grantor, such
         Grantor shall furnish to the Collateral Agent reports showing
         reconciliations, aging and test verifications of, and trial balances

         authority at any time after the occurrence and during the continuance
         of an Event of Default. If required by the Collateral Agent at any time
         after the occurrence and during the continuance of an Event of Default,

         collected by each Grantor, shall be forthwith (and, in any event,
         within two Business Days) deposited by such Grantor in the exact form
         received, duly indorsed by such Grantor to the Collateral Agent if

         the EPN Group Lenders and the Marco Polo Lenders, segregated from other
         funds of any such Grantor. Each deposit of any such Proceeds shall be
         accompanied by a report identifying in reasonable detail the nature and
         source of the payments included in the deposit. All Proceeds
         constituting collections of Accounts while held by the Collateral Agent
         (or by any Grantor in trust for the Collateral Agent for the ratable
         benefit of the EPN Group Lenders and the Marco Polo Lenders) shall
         continue to be collateral security for all of the Obligations and shall
         not constitute payment thereof until applied as hereinafter provided.
         At such intervals as may be agreed upon by each Grantor and the
         Collateral Agent, or, if an Event of Default shall have occurred and be
         continuing, at any time at the Collateral Agent's election, the

         Collateral Agent shall apply all or any part of the funds on deposit in
         said special collateral account on account of the Obligations in such
         order as the Collateral Agent may elect, and any part of such funds
         which the Collateral Agent elects not so to apply and deems not
         required as collateral security for the Obligations shall be paid over
         from time to time by the Collateral Agent to each Grantor or to
         whomsoever may be lawfully entitled to receive the same. At the
         Collateral Agent's request, each Grantor shall deliver to the
         Collateral Agent all original and other documents evidencing, and
         relating to, the agreements and transactions which gave rise to the
         Accounts, including, without limitation, all original orders, invoices
         and shipping receipts.

         4.       Representations and Warranties. Each Grantor hereby represents
and warrants that:

                  (a)      Title; No Other Liens. Except for the Lien granted to
         the Collateral Agent for the ratable benefit of the EPN Group Lenders
         and the Marco Polo Lenders pursuant to this Security Agreement and the
         other Liens permitted to exist on the Collateral pursuant to the EPN
         Credit Agreement or the EPNHC Credit Agreement, each Grantor owns each
         item of the Collateral free and clear of any and all Liens or claims of
         others. No security agreement, financing statement or other public
         notice with respect to all or any part of the Collateral is on file or
         of record in any public office, except such as may have been filed in
         favor of the Collateral Agent, for the ratable benefit of the EPN Group
         Lenders and the Marco Polo Lenders, pursuant to this Security Agreement
         or as may be permitted pursuant to the EPN Credit Agreement or the
         EPNHC Credit Agreement.

                  (b)      Perfected First Priority Liens. The Liens granted
         pursuant to this Security Agreement constitute perfected Liens on the
         Collateral in favor of the Collateral Agent, for the ratable benefit of
         the EPN Group Lenders and the Marco Polo Lenders, which are (except for
         any Liens on the Collateral which are permitted to exist pursuant to
         the EPN Credit Agreement or the EPNHC Credit Agreement) prior to all
         other Liens on the Collateral created by each Grantor and in existence
         on the date hereof and which are enforceable as such against all
         creditors of and purchasers from each Grantor and against any owner or
         purchaser of the real property where any of the Equipment is located
         and any present or future creditor obtaining a Lien on such real
         property. All action necessary or desirable to perfect such security
         interest in each item of the Collateral requested by the Collateral
         Agent, including the filing of financing statements in the offices
         referred to on Schedule V hereto, has been or will be duly taken.

                  (c)      Accounts. The amount represented by each Grantor to
         the EPN Group Lenders from time to time as owing by each Account Debtor
         or by all Account Debtors in respect of the Accounts, Chattel Paper,
         and Payment Intangibles will at such time be, to such Grantor's best
         knowledge, the correct amount actually owing by such Account Debtor or
         Account Debtors thereunder. No amount payable to each Grantor under or
         in connection with any Account is evidenced by any Instrument or
         Chattel Paper which has not been delivered to the Collateral Agent. The
         place where each Grantor keeps its records concerning the Accounts,
         Chattel Paper and Payment Intangibles is Four Greenway Plaza, Houston,
         Texas 77046.

<PAGE>

                  (d)      Grantor's Name, Etc. The name of each Grantor as
         indicated on the public record of such Grantor's jurisdiction of
         organization, which shows such Grantor to have been organized, is as
         set forth on Schedule IV hereto. The mailing address of each Grantor is
         Four Greenway Plaza, Houston, Texas 77046. With respect to each
         Grantor, the type of entity of such Grantor and the organizational
         identification number for such Grantor in such Grantor's jurisdiction
         of organization is correctly set forth on Schedule IV hereto. To the
         extent indicated on Schedule IV hereto, the Grantors therein identified
         were formerly known by the names set forth on Schedule IV hereto. Other
         than such names, no Grantor has used any other name or trade name.

         is the Proceeds of, Farm Products.

                  (f)      Patents and Trademarks. Schedule I hereto includes
         all Patents and Patent Licenses owned by each Grantor in its own name
         as of the date hereof. Schedule II hereto includes all Trademarks and
         Trademark Licenses owned by each Grantor in its own name as of the date
         hereof. To the best of each such Grantor's knowledge, each Patent and
         Trademark is valid, subsisting, unexpired, enforceable and has not been
         abandoned. Except as set forth in either such Schedule, none of such
         Patents and Trademarks is the subject of any licensing or franchise
         agreement. No holding, decision or judgment has been rendered by any
         Governmental Authority which would limit, cancel or question the
         validity of any Patent or Trademark. No action or proceeding is pending
         (i) seeking to limit, cancel or question the validity of any Patent or
         Trademark, or (ii) which, if adversely determined, would have a
         material adverse effect on the value of any Patent or Trademark.

                  (a)      Further Documentation; Pledge of Instruments and
         Chattel Paper. At any time and from time to time, upon the written
         request of the Collateral Agent, and at the sole expense of each
         Grantor, such Grantor will promptly and duly execute and deliver such
         further instruments and documents and take such further action as the

         preserving the full benefits of this Security Agreement and of the

         filing of any financing or continuation statements under the Uniform
         Commercial Code in effect in any jurisdiction with respect to the Liens
         created hereby. Each Grantor hereby authorizes the Collateral Agent,
         its counsel or its representative, at any time and from time to time,
         to file financing statements and

                                  Exhibit I-9

<PAGE>

         amendments to financing statements that describe the collateral covered
         by such financing statements as "all assets of the Grantor", "all
         personal property of the Grantor", or words of similar effect, 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 such Grantor under this Security Agreement. Each
         Grantor 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. A photographic or other reproduction of this Security
         Agreement shall be sufficient as a financing statement for filing in
         any jurisdiction. If any amount payable under or in connection with any
         of the Collateral shall be or become evidenced by any Instrument or
         Chattel Paper, such Instrument or Chattel Paper shall be immediately
         delivered to the Collateral Agent, duly endorsed in a manner
         satisfactory to the Collateral Agent, to be held as Collateral pursuant
         to this Security Agreement. Upon the request of the Collateral Agent or
         any of the EPN Group Lenders, each Grantor shall take or cause to be
         taken all actions (other than any actions required to be taken by the
         Collateral Agent or any of the EPN Group Lenders) necessary to cause
         the Collateral Agent to have "control" (within the meaning of Sections
         9-104, 9-105, 9-106, and 9-107 of the UCC) over any Collateral
         constituting Deposit Accounts, Electronic Chattel Paper, Investment
         Property, or Letter-of-Credit Rights, and each Grantor shall promptly
         notify the Collateral Agent and each of the EPN Group Lenders of such
         Grantor's acquisition of any such Collateral. With respect to any goods
         constituting Collateral that are in the possession of a "bailee"
         (within the meaning of Section 9-312 of the UCC), each Grantor shall
         take or cause to be taken all actions (other than any actions required
         to be taken by the Collateral Agent or any of the EPN Group Lenders)
         necessary to cause the Collateral Agent to have a perfected security
         interest in such Collateral pursuant to the provisions of Section 9-312
         of the UCC, and such Grantor shall provide prompt notice to the
         Collateral Agent and each of the EPN Group Lenders of any such
         Collateral then in the possession of such a "bailee".

                  (b)      Indemnification. Each Grantor agrees to pay and to
         save the Collateral Agent and each of the EPN Group Lenders harmless
         from any and all liabilities and reasonable costs and expenses
         (including, without limitation, legal fees and expenses), (i) with
         respect to, or resulting from, any delay in paying, any and all excise,
         sales or other taxes which may be payable or determined to be payable
         with respect to any of the Collateral, (ii) with respect to, or
         resulting from, any delay in complying with any Requirement of Law
         applicable to any of the Collateral or (iii) in connection with any of
         the transactions contemplated by this Security Agreement. In any suit,
         proceeding or action brought by the Collateral Agent or any of the EPN
         Group Lenders under any Account, Chattel Paper, or Payment Intangibles,
         for any sum owing thereunder, or to enforce any provisions of any
         Account, Chattel Paper, or Payment Intangible, each Grantor will save,
         indemnify and keep the Collateral Agent and any of such EPN Group
         Lenders harmless from and against all reasonable expense, loss or
         damage suffered by reason of any defense, setoff, counterclaim,
         recoupment or reduction or liability whatsoever of the Account Debtor
         or obligor thereunder, arising out of a breach by any Grantor of any
         obligation thereunder or arising out of any other agreement,
         indebtedness or liability at any time owing to or in favor of such
         Account Debtor or obligor or its successors from such Debtor.

         of the Collateral, including, without limitation, a record of all
         payments received and all credits granted with respect to the Accounts.
         For the Collateral Agent's and the EPN Group Lenders' further security,
         the Collateral Agent, for the ratable benefit of the EPN Group Lenders
         and the Marco Polo Lenders, shall have a security interest in all of
         each Grantor's books and records pertaining to the Collateral, and each
         Grantor shall turn over any such books and records to the Collateral
         Agent or to its representatives during normal business hours at the
         request of the Collateral Agent.

                  (d)      Right of Inspection. The Collateral Agent and the EPN
         Group Lenders shall at all times have full and free access during
         normal business hours to all the books, correspondence and records of
         each Grantor, and the Collateral Agent and the EPN Group Lenders and
         their respective representatives may examine the same, take extracts
         therefrom and make photocopies thereof, and each Grantor agrees to
         render to the Collateral Agent and the EPN Group Lenders, at such
         Grantor's cost and expense, such clerical and other assistance as may
         be reasonably requested with regard thereto. The Collateral Agent and
         the EPN Group Lenders and their respective representatives shall at all
         times also have the right to enter into and upon any premises where any
         of the Inventory or Equipment is located for the purpose of inspecting
         the same, observing its use or otherwise protecting its interests
         therein.

                  (e)      Compliance with Laws, etc. Each Grantor will comply
         in all material respects with all Requirements of Law applicable to the
         Collateral or any part thereof or to the operation of such Grantor's
         business; provided, however, that such Grantor may contest any
         Requirement of Law in any reasonable manner which shall not, in the
         sole opinion of the Collateral Agent, adversely affect the Collateral
         Agent's or the EPN Group Lenders' rights or the priority of their Liens
         on the Collateral.

                  (f)      Compliance with Contractual Obligations. Each Grantor
         will perform and comply in all material respects with all its
         Contractual Obligations relating to the Collateral.

                  (g)      Payment of Obligations. Each Grantor will pay
         promptly when due all taxes, assessments and governmental charges or
         levies imposed upon the Collateral or in respect of its income or
         profits therefrom, as well as all claims of any kind (including,
         without limitation, claims for labor, materials and supplies) against
         or with respect to the Collateral, except that no such charge need be
         paid if (i) the validity thereof is being contested in good faith by
         appropriate proceedings, (ii) such proceedings do not involve any
         material danger of the sale, forfeiture or loss of any of the
         Collateral or any interest therein and (iii) such charge is adequately
         reserved against on such Grantor's books in accordance with GAAP.

                  (h)      Limitation on Liens on Collateral. Each Grantor will
         not create, incur or permit to exist, will defend the Collateral
         against, and will take such other action as is necessary to remove, any
         Lien or claim on or to the Collateral, other than the Liens created
         hereby and other than as permitted pursuant to the EPN Credit Agreement
         or the

                  (i)      Limitations on Dispositions of Collateral. The
         Collateral Agent and the EPN Group Lenders do not authorize, and each

         modify, terminate or waive any provision of any Chattel Paper or any
         agreement giving rise to an Account or Payment Intangible in any manner

         value of such Chattel Paper, Payment Intangible or Account as
         Collateral, (ii) fail to exercise promptly and diligently each and
         every material right which it may have under any Chattel Paper and each

         credit or discount whatsoever thereon.

                  (m)      Maintenance of Equipment. Each Grantor will maintain
         each item of Equipment in good operating condition, ordinary wear and
         tear and immaterial impairments of value and damage by the elements

         recognizes that financing statements pertaining to the Collateral have

         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

         any notice furnished pursuant to this subsection, each 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.

                           (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)

                  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.

                  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

                           (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. If any Grantor shall at any
         time hold or acquire a Commercial Tort Claim that satisfies the
         requirements of the following sentence, such Grantor shall, within
         thirty (30) days after such Commercial Tort Claim satisfies such
         requirements, notify the Collateral Agent and the EPN Group Lenders in
         a writing signed

                                  Exhibit I-14

<PAGE>

         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

<PAGE>

                  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

<PAGE>

         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

<PAGE>

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

<PAGE>

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

<PAGE>

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.

                    ADDENDUM TO SUBSIDIARY SECURITY AGREEMENT

         ADDENDUM, dated as of _____________, 200_ (this "Addendum"), to that
Consolidated Amended and Restated Subsidiary Security Agreement, dated as of
October 10, 2002 (as amended, supplemented or otherwise modified prior to the
date hereof, the "Subsidiary Security Agreement"), made by each of the Grantors
listed below in favor of JP MORGAN CHASE BANK, as collateral agent (in such
capacity, the "Collateral Agent") for EPN Group Lenders and the Marco Polo
Lenders referred to in the Subsidiary Security Agreement. Unless otherwise
defined herein, terms defined in the Subsidiary Security Agreement are used
herein as therein defined.

                              W I T N E S S E T H :

         WHEREAS, [NAME OF NEW GRANTOR], [a _________ limited liability company]
[a _________________ corporation] [a __________________ partnership] (the "New
Grantor"), has become a Subsidiary of one of the EPN Group Borrowers; and

         WHEREAS, pursuant to subsection 8.17 of the EPN Credit Agreement [or
Section 8.17 of the EPNHC Credit Agreement], the New Grantor is required to
become a party to the Subsidiary Security Agreement;

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the New Grantor hereby:

                  (i)      agrees to all of the provisions of the Subsidiary
         Security Agreement, and

                  (ii)     effective on the date hereof, becomes a party to the
         Subsidiary Security Agreement, as a Grantor, with the same effect as if
         the New Grantor were an original signatory thereto (with the
         representations and warranties contained therein being deemed to be
         made by the New Grantor as of the date hereof);

                  (iii)    represents and warrants as follows:

                           (a)      Schedule I hereto includes all Patents and
                  Patent Licenses owned by New Grantor in its own name as of the
                  date hereof. Schedule II hereto includes all Trademarks and
                  Trademark Licenses owned by New Grantor in its own name as of
                  the date hereof. To the best of New Grantor's knowledge, each
                  Patent and Trademark is valid, subsisting, unexpired,

                  either such Schedule, none of such Patents and Trademarks is
                  the subject of any licensing or franchise agreement. No
                  holding, decision or judgment has been rendered by any
                  Governmental Authority which would limit, cancel or question
                  the validity of any Patent or Trademark. No action or
                  proceeding is pending (i) seeking to limit, cancel or question
                  the

                              Exhibit I Schedules-9

<PAGE>

                  validity of any Patent or Trademark, or (ii) which, if
                  adversely determined, would have a material adverse effect on
                  the value of any Patent or Trademark;

                           (b)      Schedule III hereto is a complete and
                  correct list of all Vehicles owned by New Grantor;

                           (c)      The name of New Grantor as indicated on the
                  public record of New Grantor's jurisdiction of organization,
                  which shows New Grantor to have been organized, is as set
                  forth on Schedule IV hereto. The mailing address of New
                  Grantor is Four Greenway Plaza, Houston, Texas 77046. The type

                  number for New Grantor in New Grantor's jurisdiction of
                  organization is correctly set forth on Schedule IV hereto. To
                  the extent indicated on Schedule IV hereto, New Grantor was
                  formerly known by the names set forth on Schedule IV hereto.
                  Other than such names, New Grantor has not used any other name
                  or trade name;

                           (d)      All action necessary or desirable to perfect
                  the Liens and security interest in each item of New Grantor's
                  Collateral requested by the Collateral Agent, including the
                  filing of financing statements in the offices referred to on
                  Schedule V hereto, has been or will be duly taken; and

                           (d)      To the extent indicated on Schedule VI
                  attached hereto, New Grantor is a Person primarily engaged in

                  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

<PAGE>

                  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

<PAGE>

                  (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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

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

applicable, including, without limitation, releases of guaranties or (subject to
Section 9) Collateral and settlements with the EPN Group Loan Parties and all
other Persons, in the case of either clause (i) or (ii) above, without the
consent of any Senior Secured Acquisition Term Loan Lender or the Senior Secured
Acquisition Term Loan Administrative Agent, except to the extent otherwise
required under the Senior Secured Acquisition Term Loan Credit Agreement, and
without affecting the agreements of each Senior Secured Acquisition Term Loan
Lender and the Senior Secured Acquisition Term Loan Administrative Agent as
contained in this Agreement.

         8.       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

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).

                  (c)      The notices, statements, directions and certificates
requested under this Section 9 shall be in full authority for and direction to
the Collateral Agent to execute and deliver the releases and terminations
referred to in this Section 9 and the Collateral Agent shall promptly do so. The
Collateral Agent in so doing shall have no liability therefore to any Person.

         10.      PROVISIONS DEFINING RELATIVE RIGHTS. This Agreement is
intended solely for the purpose of defining the relative rights of the
Collateral Agent, the EPN Administrative Agent, the EPN Lenders, the EPNHC
Administrative Agent, the EPNHC Lenders, the Senior Secured Acquisition Term
Loan Administrative Agent, the Senior Secured Acquisition Term Loan Lenders, the
Marco Polo Administrative Agent and the Marco Polo Lenders, and, with respect to
Sections 8 and 9 only, the EPN Group Loan Parties, and no other Person shall
have any right, benefit or other interest under this Agreement.

                                    EXHIBIT O

                        DESCRIPTION OF CHACO TRANSACTIONS

I.       The Chaco Plant

         The Chaco Plant, the third largest natural gas processing plant in the
United States measured by liquids produced, is located in the San Juan Basin in
New Mexico. It is capable of processing up to 600 Mmcf/d of natural gas and
handling up to 50,000 bbls/d of NGLs. The Chaco Plant is a state of the art
cryogenic plant that uses high pressures and extremely low temperatures to
remove water, impurities and excess hydrocarbon liquids from the raw natural gas
stream and recover ethane as well as propane and the heavier hydrocarbons. The
Chaco Plant receives and processes natural gas from the San Juan Gathering
System (the "Gathering System"), an over 5,500 mile natural gas gathering system
in New Mexico owned and operated by an Affiliate of El Paso Field Services, L.P.
("Field Services").

II.      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

<PAGE>

                  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.
