              BBD's approval of the transactions contemplated by this Agreement
              (the "BBD Approval").

         (i)  Neither Murphy or Callon shall claim (directly or indirectly) any
              additional allowance for depreciation under Section 168(k) of the

                                  ARTICLE VII

                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                                 INDEMNIFICATION

         7.1 Survival of Representations and Warranties.

         All of the Parties' representations, warranties, covenants, and
agreements in this Agreement or in any certificate or instrument delivered
pursuant to this Agreement shall survive the Closing of the transactions
contemplated in this Agreement.

         7.2 Indemnification by Transaction Parties.

         Each of the Parties (a "Transaction Indemnifying Party") shall
reimburse, indemnify, defend and hold harmless the other Parties from and
against any and all claims, demands, lawsuits, liabilities, judgments, damages,
awards, fines, costs, expenses, fees, penalties, deficiencies, losses, amounts
paid or incurred in defense and/or settlement and related expenses, including
without limitation interest, court and other legal proceeding costs, reasonable
fees of attorneys, accountants, and other experts or other expenses of
litigation or other proceedings or of any claim, default or assessment
(collectively, "Losses") incurred by each of the other Parties, and its and
their officers, directors, employees, and agents (a "Transaction Indemnified
Party"), in each case net of insurance proceeds if and when received by such
Transaction Indemnified Party in connection with such Losses, directly or
indirectly as a result of any of the following events (an "Indemnification
Event"):

         (a)  any inaccuracy in, or breach of, a representation or warranty of
              the Transaction Indemnifying Party contained herein (or in any
              certificate or instrument delivered by the Transaction
              Indemnifying Party pursuant to this Agreement);

         (b)  any failure by the Transaction Indemnifying Party to perform or
              comply with any of its covenants or agreements contained herein;
              and/or

         (c)  third party claims related to ownership, operation, use, or
              condition of the Medusa Spar prior to Closing, regardless of when
              any such claim arises, in which case Murphy and Callon shall each
              be a Transaction Indemnifying Party, and Medusa Spar LLC and OII,
              and its and their officers, directors, employees and agents, shall
              be the Transaction Indemnified Party;

provided, however, that no indemnification shall be owed by a Transaction
Indemnifying Party to a Transaction Indemnified Party under this Section 7.2,
and no amount of indemnity shall be payable by a Transaction Indemnifying Party
in the case of a claim by any Transaction Indemnified Party under this Section
7.2, unless and until an Indemnified Event has occurred and

                                       16

<PAGE>

is continuing for a period of thirty (30) business days after written notice
thereof given by the Transaction Indemnified Party to the Transaction
Indemnifying Party in accordance with Section 8.1 of this Agreement.

         7.3 Matters Involving Third Parties.

         (a)  If any third party shall notify any Party entitled to
              indemnification under Section 7.2 (the "Indemnified Party") with
              respect to any matter (a "Third Party Claim") which may give rise
              to a claim for indemnification against any other Party hereto (the
              "Indemnifying Party") under this Article VII, then the Indemnified
              Party shall promptly notify (and in any event by the sooner to
              occur of (i) 10 days after receipt of notice by it, and (ii) five
              days prior to the date a responsive pleading is due (which
              notification shall be made by either facsimile or overnight
              delivery pursuant to Section 8.1 hereof) each Indemnifying Party
              thereof in writing; provided, however, that no delay on the part
              of the Indemnified Party in notifying any Indemnifying Party shall
              relieve the Indemnifying Party from any obligation hereunder
              unless (and then solely to the extent) the Indemnifying Party
              thereby is prejudiced.

         (b)  Any Indemnifying Party will have the right to defend the
              Indemnified Party against the Third Party Claim with counsel of
              its choice reasonably satisfactory to the Indemnified Party so
              long as (i) the Indemnifying Party promptly notifies the
              Indemnified Party in writing that the Indemnifying Party will
              indemnify the Indemnified Party, to the extent indemnification is
              provided for under Section 7.2, (ii) the Indemnifying Party
              provides the Indemnified Party with evidence reasonably acceptable
              to the Indemnified Party that the Indemnifying Party will have the
              financial resources to defend against the Third Party Claim and
              fulfill its indemnification obligations hereunder, and (iii) the
              Indemnifying Party conducts the defense of the Third Party Claim
              actively and diligently.

         (c)  So long as the Indemnifying Party is conducting the defense of the
              Third Party Claim in accordance with Section 7.3(b) above, (i) the
              Indemnified Party may retain separate co-counsel at its sole cost
              and expense and participate in the defense of the Third Party
              Claim, (ii) the Indemnified Party will not consent to the entry of
              any judgment or enter into any settlement with respect to the
              Third Party Claim without the prior written consent of the
              Indemnifying Party (which consent shall not unreasonably be
              withheld), (iii) the Indemnifying Party will not consent to the
              entry of any judgment or enter into any settlement with respect to
              the Third Party Claim unless a written agreement is obtained
              releasing the Indemnified Party from all liability thereunder,
              (iv) the Indemnifying Party will

                                       17

<PAGE>

              not consent to the entry of any judgment or enter into any
              settlement with respect to a Third Party Claim, which involves an
              injunction or other equitable relief, without the consent of the
              Indemnified Party, which consent will not be unreasonably
              withheld, and (v) the Indemnifying Party will not consent to the
              entry of any judgment or enter into any settlement with respect to
              a Third Party Claim which will, in the good faith judgment of the
              Indemnified Party, likely establish a precedential custom or
              practice adverse to the continuing business interests of the
              Indemnified Party.

         (d)  In the event any of the conditions in Section 7.3(b) above is or
              becomes unsatisfied, however, (i) the Indemnified Party may defend
              against, and consent to the entry of any judgment or enter into
              any settlement with respect to, the Third Party Claim in any
              manner it may deem appropriate (and the Indemnified Party need not
              consult with, or obtain any consent from, any Indemnifying Party
              in connection therewith), (ii) the Indemnifying Parties will
              reimburse the Indemnified Party promptly and periodically for the
              costs of defending against the Third Party Claim (including
              attorneys' fees and expenses), provided that the Third Party Claim
              is subject to indemnification under Section 7.2 and (iii) the
              Indemnifying Parties will remain responsible for any Losses the
              Indemnified Party may incur to the extent provided in Section 7.2.

         7.4  Limitation on Damages.

         Except for such damages that must be paid by an Indemnified Party to a
third party, no Party shall be entitled to indemnification under this Article
VII for incidental, indirect, consequential, exemplary or punitive damages;
provided, however that it is understood and agreed that diminution in value of
the Medusa Spar shall constitute actual damages.

         7.5 Exclusive Remedies.

         The remedies provided in this Article VII constitute the sole and
exclusive remedies available to each of the Parties for recoveries against the
other Parties for breaches or failures to comply with or non-fulfillments of the
representations, warranties, covenants and agreements of this Agreement or in
any certificate or document furnished to any of the Parties by any other Party
pursuant to this Agreement except that nothing in this Agreement shall limit the
right of a Party to pursue any appropriate remedy at equity, including specific
performance for breach of any of the covenants of any other Party contained
herein or rescission based upon allegations of fraud or willful misconduct in
connection with this Agreement.

illegal, void or unenforceable, the remainder of this Agreement will continue in

thereof and of the amount of such Lender's Loan to be made as part of the Term

Agent will make the Term Loan available to the Borrower by promptly crediting
the amounts so received, in like funds, to an account of the Borrower maintained
with the Administrative Agent in Atlanta, Georgia and designated by the Borrower
in the Borrowing Request. Nothing herein shall be deemed to obligate any Lender
to obtain the funds for its Loan in any particular place or manner or to
constitute a representation by any Lender that it has obtained or will obtain
the funds for its Loan in any particular place or manner.

         (b) Presumption of Funding by the Lenders. Unless the Administrative
Agent shall have received notice from a Lender prior to Funding Date that such
Lender will not make available to the Administrative Agent such Lender's share
of the Term Loan, the Administrative Agent may assume that such Lender has made
such share available on such date in accordance with Section 2.04(a) and may, in
reliance upon such assumption, make available to the Borrower a corresponding
amount. In such event, if a Lender has not in fact made its share of the Term
Loan available to the Administrative Agent, then the applicable Lender and the
Borrower severally agree to pay to the Administrative Agent forthwith on demand
such corresponding amount with interest thereon, for each day from and including
the date such amount is made available to the Borrower to but excluding the date
of payment to the Administrative Agent, at (i)

a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation or (ii) in the case of the Borrower,

the Administrative Agent, then such amount shall constitute such Lender's Loan
included in the Term Loan.

         (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not
exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest
Period; or

         (b) the Administrative Agent is advised by the Majority Lenders that
the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period
will not adequately and fairly reflect the cost to such Lenders of making or
maintaining their Loans included in the Term Loan for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, the Loans comprising
the Term Loan shall not be continued as Eurodollar Loans at the end of the then
current Interest Period, but instead, shall be converted to ABR Loans at the end
of the then current Interest Period.

         Section 3.04 Prepayments.

         (a) Optional Prepayments. The Borrower shall have the right at any time
and from time to time to prepay the Term Loan in whole or in part, subject to
prior notice in accordance with Section 3.04(b). In connection with any such
prepayment, in addition to any other amounts required to be paid hereunder, the
Borrower shall pay any unwind payments or other amounts due as a result of such
prepayment under any Swap Agreement entered into by the Borrower pursuant to
Section 6.01(m), when and as the same shall become due and payable.

         (b) Notice and Terms of Optional Prepayment. The Borrower shall notify
the Administrative Agent by telephone (confirmed by telecopy) of any prepayment
hereunder, not later than 12:00 noon, New York City time, three Business Days
before the date of prepayment. Each such notice shall be irrevocable and shall
specify the prepayment date and the principal amount of the Term Loan to be
prepaid. Promptly following receipt of any such notice relating to the Term
Loan, the Administrative Agent shall advise the Lenders of the contents thereof.
Each partial prepayment of the Term Loan shall be in an aggregate amount that is
an integral multiple of $100,000 and not less than $1,000,000.

         (c) Application of Prepayments. Each prepayment made pursuant to
Section 3.04 shall be applied ratably to the Loans and to the scheduled
principal payments of the Term Loan in the inverse order of their maturity.
Prepayments shall be accompanied by accrued interest to the extent required by
Section 3.02.

         (d) No Premium or Penalty. Prepayments permitted or required under this
Section 3.04 shall be without premium or penalty, except as required under
Section 5.02.

         Section 3.05 Fees. The Borrower shall pay to the Administrative Agent,
the Arranger, and the Lenders, for their respective accounts, such fees as shall
have been agreed upon in writing with the Administrative Agent in amounts and at
times so specified.

                                   ARTICLE IV
                PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS

         Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of
Set-offs.

         (a) Payments by the Borrower. The Borrower shall make each payment
required to be made by it hereunder (whether of principal, interest, fees or of
amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise)
prior to 12:00 noon, New York City time, on the date when due, in immediately
available funds, without defense, deduction, recoupment, set-off or
counterclaim. Fees, once paid, shall be fully earned and shall not be refundable
under any circumstances. Any amounts received after such time on any date may,
in the discretion of the Administrative Agent, be deemed to have been received
on the next succeeding Business Day for purposes of calculating interest
thereon. All such payments shall be made to the Administrative Agent at its
offices specified in Section 12.01, except that payments pursuant to Section
5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the
Persons entitled thereto. The Administrative Agent shall distribute any such
payments received by it for the account of any other Person to the appropriate
recipient promptly following receipt thereof. If any payment hereunder shall be
due on a day that is not a Business Day, the date for payment shall be extended
to the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension.
All payments hereunder shall be made in dollars.

         (b) Application of Insufficient Payments. If at any time insufficient
funds are received by and available to the Administrative Agent to pay fully all
amounts of principal, interest and fees then due hereunder, such funds shall be
applied (i) first, towards payment of interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties and (ii) second, towards payment of
principal then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties.

         (c) Sharing of Payments by Lenders. If any Lender shall, by exercising
any right of set-off or counterclaim or otherwise, obtain payment in respect of
any principal of or interest on its Loan resulting in such Lender receiving
payment of a greater proportion of the aggregate amount of its Loan and accrued
interest thereon than the proportion received by any other Lender, then the
Lender receiving such greater proportion shall purchase (for cash at face value)
participations in the Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are
purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest and (ii) the
provisions of this Section 4.01(c) shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loan to any assignee
or participant, other than to the Borrower (as to which the provisions of this
Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees,
to the extent it may effectively do so under applicable law, that any Lender
acquiring a participation pursuant to the foregoing arrangements

                                       24

<PAGE>

may exercise against the Borrower rights of set-off and counterclaim with
respect to such participation as fully as if such Lender were a direct creditor
of the Borrower in the amount of such participation.

         Section 4.02 Presumption of Payment by the Borrower. Unless the
Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of
the Lenders that the Borrower will not make such payment, the Administrative
Agent may assume that the Borrower has made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders the amount due. In such event, if the Borrower has not in fact made such
payment, then each of the Lenders severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

         Section 4.03 Certain Deductions by the Administrative Agent. If any
Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or Section 4.02 then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender's obligations under such Sections until all such
unsatisfied obligations are fully paid.

           INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY

         Section 5.01 Increased Costs.

         (a) Eurodollar Changes in Law. If any Change in Law shall:

              (i) impose, modify or deem applicable any reserve, special deposit
         or similar requirement against assets of, deposits with or for the
         account of, or credit extended by, any Lender (except any such reserve
         requirement reflected in the Adjusted LIBO Rate); or

              (ii) impose on any Lender or the London interbank market any other
         condition affecting this Agreement or the Eurodollar Loan made by such
         Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining its Eurodollar Loan (or of maintaining its
obligation to make such Loan) or to reduce the amount of any sum received or
receivable by such Lender (whether of principal, interest or otherwise), then
the Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

         (b) Capital Requirements. If any Lender determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's capital or on the capital of such Lender's or
holding company, if any, as a consequence

                                       26

<PAGE>

of this Agreement or the Loan made by such Lender to a level below that which
such Lender or such Lender's holding company could have achieved but for such
Change in Law (taking into consideration such Lender's policies and the policies
of such Lender's holding company with respect to capital adequacy), then from
time to time the Borrower will pay to such Lender such additional amount or
amounts as will compensate such Lender or such Lender's holding company for any
such reduction suffered.

         (c) Certificates. A certificate of a Lender setting forth the amount or
amounts necessary to compensate such Lender or its holding company, as the case
may be, as specified in Section 5.01(a) or (b) shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

         (d) Effect of Failure or Delay in Requesting Compensation. Failure or
delay on the part of any Lender to demand compensation pursuant to this Section
5.01 shall not constitute a waiver of such Lender's right to demand such
compensation; provided that the Borrower shall not be required to compensate a
Lender pursuant to this Section 5.01 for any increased costs or reductions
incurred more than 365 days prior to the date that such Lender notifies the
Borrower of the Change in Law giving rise to such increased costs or reductions
and of such Lender's intention to claim compensation therefor; provided further
that, if the Change in Law giving rise to such increased costs or reductions is
retroactive, then the 365-day period referred to above shall be extended to
include the period of retroactive effect thereof.

         Section 5.02 Break Funding Payments. In the event of (a) the payment of
any principal of any Eurodollar Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any Eurodollar Loan into an ABR Loan other than on the last
day of the Interest Period applicable thereto, (c) the failure to borrow or
prepay any Eurodollar Loan on the date specified in any notice delivered
pursuant hereto, or (d) the failure to continue any Loan as a Eurodollar Loan at
the beginning of the next succeeding Interest Period, then, in any such event,
the Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. Such loss, cost or expense to any Lender shall be
deemed to include an amount determined by such Lender to be the excess, if any,
of (i) the amount of interest which would have accrued on the principal amount
of such Loan had such event not occurred, at the Adjusted LIBO Rate that would
have been applicable to such Loan, for the period from the date of such event to
the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow or continue, for the period that would have been the Interest
Period for such Loan), over (ii) the amount of interest which would accrue on
such principal amount for such period at the interest rate which such Lender
would bid were it to bid, at the commencement of such period, for dollar
deposits of a comparable amount and period from other banks in the eurodollar
market.

A certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section 5.02 shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

         Section 5.03 Taxes.

                                       26

<PAGE>

         (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower under any Loan Document shall be made free and
clear of and without deduction for any Indemnified Taxes or Other Taxes;
provided that if the Borrower shall be required to deduct any Indemnified Taxes
or Other Taxes from such payments, then (i) the sum payable shall be increased
as necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 5.03(a)), the
Administrative Agent or Lender (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with
applicable law.

         (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any
Other Taxes to the relevant Governmental Authority in accordance with applicable
law.

         (c) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent and each Lender, within 10 days after written demand
therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent or such Lender, as the case may be, on or with respect
to any payment by or on account of any obligation of the Borrower hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 5.03) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate of the
Administrative Agent or a Lender as to the amount of such payment or liability
under this Section 5.03 shall be delivered to the Borrower and shall be
conclusive absent manifest error.

         (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority,
the Borrower shall deliver to the Administrative Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Administrative Agent.

         (e) Foreign Lenders. Any Foreign Lender that is entitled to an
exemption from or reduction of withholding tax under the law of the jurisdiction
in which the Borrower is located, or any treaty to which such jurisdiction is a
party, with respect to payments under this Agreement or any other Loan Document
shall deliver to the Borrower (with a copy to the Administrative Agent), at the
time or times prescribed by applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrower as will permit such payments to be made without withholding or at a
reduced rate.

         Section 5.04 Mitigation Obligations. If any Lender requests
compensation under Section 5.01, or if the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 5.03, then such Lender shall use reasonable
efforts to designate a different lending office for funding or booking its Loans
hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant
to Section 5.01 or Section 5.03, as the case

                                       27

<PAGE>

may be, in the future and (ii) would not subject such Lender to any unreimbursed
cost or expense and would not otherwise be disadvantageous to such Lender. The
Borrower hereby agrees to pay all reasonable costs and expenses incurred by any
Lender in connection with any such designation or assignment.

         Section 5.05 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
applicable lending office to honor its obligation to make or maintain a
Eurodollar Loan either generally or having a particular Interest Period
hereunder, then (a) such Lender shall promptly notify the Borrower and the
Administrative Agent thereof and such Lender's obligation to make such
Eurodollar Loan shall be suspended (the "Affected Loan") until such time as such
Lender may again make and maintain such Eurodollar Loan and (b) any Affected
Loan which would otherwise be made by such Lender shall be made instead as an
ABR Loan (and, if such Lender so requests by notice to the Borrower and the
Administrative Agent, any Affected Loan of such Lender then outstanding shall be
automatically converted into ABR Loan on the date specified by such Lender in
such notice) and, to the extent that any Affected Loan is so made as (or
converted into) an ABR Loan, all payments of principal which would otherwise be
applied to such Lender's Affected Loan shall be applied instead to its ABR Loan.

                                   ARTICLE VI

         The Borrower represents and warrants to the Lenders that:

         Section 7.01 Organization; Powers. Each of the Loan Parties is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, has all requisite power and authority, and has
all material governmental licenses, authorizations, consents and approvals
necessary, to own its assets and to carry on its business as now conducted, and
is qualified to do business in, and is in good standing in, every jurisdiction
where such qualification is required, except where failure to have such power,
authority, licenses, authorizations, consents, approvals and qualifications
could not reasonably be expected to have a Material Adverse Effect.

         Section 7.02 Authority; Enforceability. The Transactions are within
each Loan Party's corporate powers and have been duly authorized by all
necessary corporate and, if required, stockholder or member action (including,
without limitation, any action required to be taken by any class of directors,
members or managers of any Loan Party, whether interested or disinterested, in
order to ensure the due authorization of the Transactions). Each Loan Document
and Medusa Spar Document to which each Loan Party is a party has been duly
executed and delivered by such Loan Party and constitutes a legal, valid and
binding obligation of such Loan Party, as applicable, enforceable in accordance
with its terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally and subject to
general principles of equity, regardless of whether considered in a proceeding
in equity or at law.

         Section 7.03 Approvals; No Conflicts. The Transactions (a) do not
require any consent or approval of, registration or filing with, or any other
action by, any Governmental Authority or any other third Person (including
shareholders or members or any class of directors, members or managers, whether
interested or disinterested, of any Loan Party or any other Person), nor is any
such consent, approval, registration, filing or other action necessary for the
validity or enforceability of any Loan Document or Medusa Spar Document or the
consummation of the transactions contemplated thereby, except such as have been
obtained or made and are in full

                                       32

<PAGE>

force and effect other than (i) the recording and filing of the Security
Instruments as required by this Agreement and (ii) those third party approvals
or consents which, if not made or obtained, would not cause a Default hereunder,
could not reasonably be expected to have a Material Adverse Effect or do not
have an adverse effect on the enforceability of the Loan Documents, (b) will not
violate any applicable law or regulation or the Organization Documents of any
Loan Party or any order of any Governmental Authority, (c) will not violate or
result in a default under any indenture, agreement or other instrument binding
upon any Loan Party or its Properties, or give rise to a right thereunder to
require any payment to be made by any Loan Party and (d) will not result in the
creation or imposition of any Lien on any Property of any Loan Party (other than
the Liens created by the Loan Documents).

         Section 7.04 Financial Condition; No Material Adverse Change.

         (a) The Borrower has heretofore furnished to the Lenders (i) the
Borrower's pro forma balance sheet and projected statements of income, members'
equity and cash flows for the period beginning the Effective Date and ending
December 31, 2006; and (ii) MOC's consolidated balance sheet and statements of
income, stockholders' equity and cash flows (A) as of and for the fiscal year
ended December 31, 2002, reported on by KPMG, independent public accountants,
and (B) as of and for the fiscal quarter and the portion of the fiscal year
ended September 30, 2003, certified by its chief financial officer. The
Borrower's financial statements were prepared in good faith based upon
assumptions believed to be reasonable at the time. MOC's financial statements
present fairly, in all material respects, the financial position and results of
operations and cash flows of MOC and its Consolidated Subsidiaries, as of such
dates and for such periods in accordance with GAAP, subject to year-end audit
adjustments and the absence of footnotes in the case of the unaudited quarterly
financial statements.

circumstance that has had or could reasonably be expected to have a Material
Adverse Effect.

         (c) The Borrower does not have on the date hereof any material Debt
(including Disqualified Capital Stock) or any contingent liabilities,
off-balance sheet liabilities or partnerships, liabilities for taxes, unusual
forward or long-term commitments or unrealized or anticipated losses from any
unfavorable commitments, except as referred to or reflected or provided for in
the Financial Statements and under Swap Agreements disclosed pursuant to Section
7.19.

         (a) Except as set forth on Schedule 7.05, there are no actions, suits,
investigations or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Borrower, threatened
against or affecting the Borrower or involving the Medusa Spar, the Medusa Spar
Transactions or the Dedicated Blocks (i) as to which there is a reasonable
possibility of an adverse determination that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect, (ii) that involve any Loan Document, any Medusa Spar
Document, the Medusa Spar, the Medusa Spar Transactions, the Dedicated Blocks or
the Transactions or (iii) that could

                                       33

<PAGE>

reasonably be expected to impair the consummation of the Medusa Spar
Transactions on the time and in the manner contemplated by the Medusa Spar
Documents.

         (b) Since the date of this Agreement, there has been no change in the
status of the matters disclosed in Schedule 7.05 that, individually or in the
aggregate, has resulted in, or materially increased the likelihood of, a
Material Adverse Effect.

         Section 7.06 Environmental Matters. Except as could not be reasonably
expected to have a Material Adverse Effect (or with respect to (c), (d) and (e)
below, where the failure to take such actions could not be reasonably expected
to have a Material Adverse Effect):

         (a) neither any Property of the Borrower nor the operations conducted
thereon nor the Dedicated Blocks nor the operations conducted thereon violate
any order or requirement of any court or Governmental Authority or any
Environmental Laws.

         (b) no Property of the Borrower nor the operations currently conducted
thereon nor the Dedicated Blocks nor the operations currently conducted thereon
or, to the knowledge of the Borrower, by any prior owner or operator of such
Property or operation, are in violation of or subject to any existing, pending
or threatened action, suit, investigation, inquiry or proceeding by or before
any court or Governmental Authority or to any remedial obligations under
Environmental Laws.

         (c) all notices, permits, licenses, exemptions, approvals or similar
authorizations, if any, required to be obtained or filed in connection with the
operation or use of any and all Property of the Borrower and the Dedicated
Blocks, including, without limitation, past or present treatment, storage,
disposal or release of a hazardous substance, oil and gas waste or solid waste
into the environment, have been duly obtained or filed, and the Borrower and the
Dedicated Blocks are in compliance with the terms and conditions of all such
notices, permits, licenses and similar authorizations.

         (d) all hazardous substances, solid waste and oil and gas waste, if
any, generated at any and all Property of the Borrower and the Dedicated Blocks
have in the past been transported, treated and disposed of in accordance with
Environmental Laws and so as not to pose an imminent and substantial
endangerment to public health or welfare or the environment, and, to the
knowledge of the Borrower, all such transport carriers and treatment and
disposal facilities have been and are operating in compliance with Environmental
Laws and so as not to pose an imminent and substantial endangerment to public
health or welfare or the environment, and are not the subject of any existing,
pending or threatened action, investigation or inquiry by any Governmental
Authority in connection with any Environmental Laws.

         (e) the Borrower has taken all steps reasonably necessary to determine
and has determined that no oil, hazardous substances, solid waste or oil and gas
waste, have been disposed of or otherwise released and there has been no
threatened release of any oil, hazardous substances, solid waste or oil and gas
waste on or to any Property of the Borrower or the Dedicated Blocks, in each
case, except in compliance with Environmental Laws and so as not to pose an
imminent and substantial endangerment to public health or welfare or the
environment.

                                       34

<PAGE>

         (f) to the extent applicable, all Property of the Borrower and the
Dedicated Blocks currently satisfies all design, operation, and equipment
requirements imposed by the OPA, and the Borrower does not have any reason to
believe that such Property, to the extent subject to the OPA, will not be able
to maintain compliance with the OPA requirements during the term of this
Agreement.

         (g) the Borrower does not have any known contingent liability or
Remedial Work in connection with any release or threatened release of any oil,
hazardous substance, solid waste or oil and gas waste into the environment, and
there is no known contingent liability or Remedial Work in connection with any
release or threatened release of any oil, hazardous substance, solid waste or
oil and gas waste into the environment associated with the Dedicated Blocks.

         Section 7.07 Compliance with the Laws and Agreements; No Defaults.

         (a) Each Loan Party is in compliance with all Governmental Requirements
applicable to it or its Property and all agreements and other instruments
binding upon it or its Property, and possesses all licenses, permits,
franchises, exemptions, approvals and other governmental authorizations
necessary for the ownership of its Property and the conduct of its business,
except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

         (b) No Loan Party is in default nor has any event or circumstance
occurred which, but for the expiration of any applicable grace period or the
giving of notice, or both, would constitute a default or would require any Loan
Party to Redeem or make any offer to Redeem under any indenture, note, credit
agreement or instrument pursuant to which any Material Indebtedness is
outstanding or by which any Loan Party or any of its Properties is bound.

         (c) No Default has occurred and is continuing.

         Section 7.08 Investment Company Act. Neither the Borrower nor any other
Loan Party is an "investment company" or a company "controlled" by an
"investment company," within the meaning of, or subject to regulation under, the
Investment Company Act of 1940, as amended.

         Section 7.09 Public Utility Holding Company Act. Neither the Borrower
nor any other Loan Party is a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," or a "public utility" within the meaning of, or
subject to regulation under, the Public Utility Holding Company Act of 1935, as
amended.

         Section 7.10 Taxes. The Borrower has timely filed or caused to be filed
all Tax returns and reports required to have been filed and has paid or caused
to be paid all Taxes required to have been paid by it, except (a) Taxes that are
being contested in good faith by appropriate proceedings and for which the
Borrower has set aside on its books adequate reserves in accordance with GAAP or
(b) to the extent that the failure to do so could not reasonably be expected to
result in a Material Adverse Effect. The charges, accruals and reserves on the
books of the Borrower in respect of Taxes and other governmental charges are, in
the reasonable

                                       35

<PAGE>

opinion of the Borrower, adequate. No Tax Lien has been filed and, to the
knowledge of the Borrower, no claim is being asserted with respect to any such
Tax or other such governmental charge.

         Section 7.11 ERISA. Neither the Borrower nor any ERISA Affiliate

         Section 7.12 Disclosure; No Material Misstatements. The Borrower has
disclosed to the Administrative Agent and the Lenders all material agreements,
instruments and corporate or other restrictions to which it is subject, and all
other matters known to it, that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect. Neither the
Information Memorandum nor any of the other reports, financial statements,
certificates or other information furnished by or on behalf of the Borrower or
any other Loan Party to the Administrative Agent or any Lender or any of their
Affiliates in connection with the negotiation of this Agreement or any other
Loan Document or delivered hereunder or under any other Loan Document (as
modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided that, with respect to projected financial
information, the Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time. There
is no fact peculiar to the Borrower or any other Loan Party which could
reasonably be expected to have a Material Adverse Effect or in the future is
reasonably likely to have a Material Adverse Effect and which has not been set
forth in this Agreement or the Loan Documents or the other documents,
certificates and statements furnished to the Administrative Agent or the Lenders
by or on behalf of the Borrower or any other Loan Party prior to, or on, the
date hereof in connection with the transactions contemplated hereby. There are
no statements or conclusions in the Initial Reserve Report or any other reserve
report delivered hereunder which are based upon or include misleading
information or fail to take into account material information regarding the
matters reported therein, it being understood that projections concerning
volumes attributable to the Dedicated Blocks and production and cost estimates
contained in the Initial Reserve Report and each other reserve report delivered
hereunder are necessarily based upon professional opinions, estimates and
projections and that the Borrower does not warrant that such opinions, estimates
and projections will ultimately prove to have been accurate.

         Section 7.13 Insurance. The Borrower has, or the Borrower's owners on
behalf of the Borrower have obtained, (a) all insurance policies sufficient for
the compliance by it with all material Governmental Requirements, the Medusa
Spar Documents and all other material agreements and (b) insurance coverage in
at least amounts and against such risk (including, without limitation, public
liability) that are usually insured against by companies similarly situated and
engaged in the same or a similar business for the assets and operations of the
Borrower. The Administrative Agent and the Lenders have been named as additional
insureds in respect of such liability insurance policies (other than the
insurance policy obtained by MOC on behalf of the Borrower issued by Oil
Insurance Limited) and the Administrative Agent, for the benefit of the Lenders,
has been named as loss payee with respect to property loss insurance.

                                       36

<PAGE>

         Section 7.14 Restriction on Liens. None of the Borrower or any Pledgor
is a party to any material agreement or arrangement, or subject to any order,
judgment, writ or decree, which either restricts or purports to restrict its
ability to grant Liens to the Administrative Agent and the Lenders on or in
respect of their Properties upon which Liens have been or are purported to be
granted under the Security Instruments to secure the Indebtedness and the Loan
Documents.

         Section 7.15 Subsidiaries. The Borrower has no Subsidiaries nor has any

organization is 3724209 (or, in each case, as set forth in a notice delivered to
the Administrative Agent pursuant to Section 8.01(j) in accordance with Section
12.01). The Borrower's principal place of business and chief executive offices
are located at the address specified in Section 12.01 (or as set forth in a

         Section 7.17 Properties; Titles, Etc.

         (a) The Borrower has good and defensible title to a 75% undivided
interest in and to the Medusa Spar and the Borrower's other Properties, free and
clear of all Liens except Liens permitted by Section 9.02.

         (b) Each of MEPC and CPOC has good and defensible title to the
Dedicated Blocks owned by it evaluated in the most recently delivered reserve
report hereunder, free and clear of all Liens except Excepted Liens and JOA
Liens. After giving full effect to the Excepted Liens, each of MEPC and CPOC
owns the net interests in production attributable to the Dedicated Blocks owned
by it as reflected in the most recently delivered reserve report hereunder, and
the ownership of the Dedicated Blocks shall not in any material respect obligate
MEPC or CPOC to bear the costs and expenses relating to the maintenance,
development and operations of the Dedicated Blocks in an amount in excess of the
working interest of the Dedicated Blocks set forth in the most recently
delivered reserve report hereunder that is not offset by a corresponding
proportionate increase in MEPC's or CPOC's net revenue interest in the Dedicated
Blocks.

         (c) All material leases and agreements necessary for the conduct of the
business of the Borrower are valid and subsisting, in full force and effect, and
there exists no default or event or circumstance which with the giving of notice
or the passage of time or both would give rise to a default under any such lease
or leases, which could reasonably be expected to have a Material Adverse Effect.

         (d) The rights and Properties presently owned, leased or licensed by
the Borrower including, without limitation, all easements and rights of way,
include all rights and Properties necessary to permit the Borrower to conduct
its business in all material respects in the same manner as its business has
been conducted prior to the date hereof, except to the extent the failure to
maintain could reasonably be expected to have a Material Adverse Effect.

                                       37

<PAGE>

         (e) All of the Properties of the Borrower which are reasonably
necessary for the operation of its business are in good working condition and
are maintained in accordance with prudent business standards.

         (f) The Borrower owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual Property material to its
business, and the use thereof by the Borrower does not infringe upon the rights
of any other Person, except for any such infringements that, individually or in
the aggregate, could not reasonably be expected to result in a Material Adverse
Effect. The Borrower either owns or has valid licenses or other rights to use
all databases, geological data, geophysical data, engineering data, seismic
data, maps, interpretations and other technical information used in its business
as presently conducted, subject to the limitations contained in the agreements
governing the use of the same, which limitations are customary for similarly
situated companies engaged in the similar businesses, with such exceptions as
could not reasonably be expected to have a Material Adverse Effect.

         Section 7.18 Maintenance of Properties. Except for such acts or
failures to act as could not be reasonably expected to have a Material Adverse
Effect, the Properties of the Borrower have been maintained, operated and
developed in a good and workmanlike manner and in conformity with all Government
Requirements and in conformity with the provisions of all leases, subleases or
other contracts and agreements to which it is a party. All pipelines, wells, gas
processing plants, platforms and other material improvements, fixtures and
equipment owned in whole or in part by the Borrower or that are necessary to
conduct normal operations are being maintained in a state adequate to conduct
normal operations, and with respect to such of the foregoing which are operated
by the Borrower, in a careful and efficient manner in accordance with the
practices of the industry and in compliance with all applicable contracts and
agreements and in compliance with all Governmental Requirements (other than
those the failure of which to maintain in accordance with this Section 7.07
could not reasonably be expect to have a Material Adverse Effect).

         Section 7.19 Swap Agreements. Schedule 7.19, as of the date hereof, and
after the date hereof, each report required to be delivered by the Borrower
pursuant to Section 8.01(d), sets forth, a true and complete list of all Swap
Agreements of the Borrower, the material terms thereof (including the type,
term, effective date, termination date and notional amounts or volumes), the net
mark to market value thereof, all credit support agreements relating thereto
(including any margin required or supplied) and the counterparty to each such
agreement.

         Section 7.20 Use of Loans. The proceeds of the Loans shall be used to
reimburse MEPC and CPOC for a portion of their respective capital contributions
to the Borrower, which amounts represent in the aggregate, an amount equal to
approximately 50% of the purchase price of an undivided 75% interest in the
Medusa Spar, and for the transaction fees and expenses associated with the
Medusa Spar Transactions. The Borrower is not engaged principally, or as one of
its important activities, in the business of extending credit for the purpose,
whether immediate, incidental or ultimate, of buying or carrying margin stock
(within the meaning of Regulation T, U or X of the Board). No part of the
proceeds of any Loan will be used for any purpose which violates the provisions
of Regulations T, U or X of the Board.

contemplated hereby, (a) the aggregate assets (after giving effect to amounts
that could reasonably be received by reason of indemnity, offset, insurance or
any similar arrangement), at a fair valuation, of the Borrower will exceed the
aggregate Debt of the Borrower, as the Debt becomes absolute and matures, (b)
the Borrower will not have incurred or intended to incur, and will not believe
that it will incur, Debt beyond its ability to pay such Debt (after taking into
account the timing and amounts of cash to be received by the Borrower and the
amounts to be payable on or in respect of its liabilities, and giving effect to
amounts that could reasonably be received by reason of indemnity, offset,
insurance or any similar arrangement) as such Debt becomes absolute and matures
and (c) the Borrower will not have (and will have no reason to believe that it
will have thereafter) unreasonably small capital for the conduct of its
business.

         Section 7.22 Medusa Spar Documents. The copies of the Medusa Spar
Documents previously delivered by the Borrower to the Administrative Agent are
true, accurate and complete and have not been amended or modified in any manner,

Administrative Agent and otherwise permitted by Section 9.17. No party to any
Medusa Spar Document is in default in respect of any term or obligation
thereunder which could reasonably be expected to have a Material Adverse Effect.

evaluation, investigation, monitoring, containment, cleanup, removal, repair,
restoration, remediation or other remedial obligations (collectively, the

prosecute to completion could reasonably be expected to have a Material Adverse
Effect; and (v) establish and implement such procedures as may be necessary to
continuously determine and assure that the Borrower's obligations under this
Section 8.10(a) are timely and fully satisfied, which failure to establish and
implement could reasonably be expected to have a Material Adverse Effect.

party against the Borrower or related to any of its Properties (including,
without limitation, the Medusa Spar) or the Dedicated Blocks of which the
Borrower has knowledge in connection with any Environmental Laws (excluding

and at the request of the Majority Lenders, shall, by notice to the Borrower,
take either or both of the following actions, at the same or different times:
(i) terminate the Commitments, and thereupon the Commitments shall terminate
immediately and (ii) declare the Notes and the Loans then outstanding to be due
and payable in whole (or in part, in which case any principal not so declared to
be due and payable may thereafter be declared to be due and payable), and
thereupon the principal of the Loans so declared to be due and payable, together
with accrued interest thereon and all fees and other obligations of the Borrower
accrued hereunder and under the Notes and the other Loan Documents, shall become
due and payable immediately, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or other notice of any kind, all of
which are hereby waived by the Borrower; and in case of an Event of Default
described in Section 10.01(l), Section 10.01(m) or Section 10.01(n), the
Commitments shall automatically terminate and the Notes and the principal of the

presentment, demand, protest or other notice of any kind, all of which are

         (b) In the case of the occurrence of an Event of Default, the
Administrative Agent and the Lenders will have all other rights and remedies

<PAGE>

         (c) All proceeds realized from the liquidation or other disposition of

         Indebtedness constituting fees, expenses, indemnities and other amounts
         payable to the Administrative Agent in its capacity as such;

             (ii) second, pro rata to payment or reimbursement of that portion

         amounts (other than principal and interest) payable to the Lenders;

            (iii) third, pro rata to payment of accrued interest on the Loans;

             (iv) fourth, pro rata to payment of principal outstanding on the
         Loans and that portion of the Indebtedness constituting Swap
         Termination Values; and

              (v) and any excess, if any, after all of the Indebtedness shall
         have been indefeasibly paid in full in cash, shall be paid to the
         Borrower or as otherwise required by any Governmental Requirement.

                                   ARTICLE XI
                                   THE AGENTS

         Section 11.01 Appointment; Powers. Each of the Lenders hereby
irrevocably appoints the Administrative Agent as its agent and authorizes the
Administrative Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Administrative Agent by the terms hereof and the
other Loan Documents, together with such actions and powers as are reasonably
incidental thereto.

         Section 11.02 Duties and Obligations of Administrative Agent. The
Administrative Agent shall not have any duties or obligations except those
expressly set forth in the Loan Documents. Without limiting the generality of
the foregoing, (a) the Administrative Agent shall not be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing (the use of the term "agent" herein and in the other Loan
Documents with reference to the Administrative Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law; rather, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties), (b) the Administrative
Agent shall not have any duty to take any discretionary action or exercise any
discretionary powers, except as provided in Section 11.03, and (c) except as
expressly set forth herein, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information
relating to the Borrower or any other Loan Party that is communicated to or
obtained by the bank serving as Administrative Agent or any of its Affiliates in
any capacity. The Administrative Agent shall be deemed not to have knowledge of
any Default unless and until written notice thereof is given to the
Administrative Agent by the Borrower or a Lender, and shall not be responsible
for or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement or any other

                                       53

<PAGE>

Loan Document, (ii) the contents of any certificate, report or other document
delivered hereunder or under any other Loan Document or in connection herewith
or therewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein or in any other Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement, any other Loan Document or any other agreement, instrument or
document, (v) the satisfaction of any condition set forth in ARTICLE VI or
elsewhere herein, other than to confirm receipt of items expressly required to
be delivered to the Administrative Agent or as to those conditions precedent
expressly required to be to the Administrative Agent's satisfaction, (vi) the
existence, value, perfection or priority of any collateral security or the
financial or other condition of the Borrower or any other Loan Party or any
other obligor or guarantor, or (vii) any failure by the Borrower or any other
Person (other than itself) to perform any of its obligations hereunder or under
any other Loan Document or the performance or observance of any covenants,
agreements or other terms or conditions set forth herein or therein. For
purposes of determining compliance with the conditions specified in ARTICLE VI,
each Lender that has signed this Agreement shall be deemed to have consented to,
approved or accepted or to be satisfied with, each document or other matter
required thereunder to be consented to or approved by or acceptable or
satisfactory to a Lender unless the Administrative Agent shall have received
notice from such Lender prior to the proposed closing date specifying its
objection thereto.

         Section 11.03 Action by Administrative Agent. The Administrative Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that the Administrative Agent is required to exercise in
writing as directed by the Majority Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in
Section 12.02) and in all cases the Administrative Agent shall be fully
justified in failing or refusing to act hereunder or under any other Loan
Documents unless it shall (a) receive written instructions from the Majority
Lenders or the Lenders, as applicable, (or such other number or percentage of
the Lenders as shall be necessary under the circumstances as provided in Section
12.02) specifying the action to be taken and (b) be indemnified to its
satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action. The
instructions as aforesaid and any action taken or failure to act pursuant
thereto by the Administrative Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, then the Administrative Agent shall take
such action with respect to such Default as shall be directed by the requisite
Lenders in the written instructions (with indemnities) described in this Section
11.03, 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 as it shall deem advisable in the best interests of the Lenders.
In no event, however, shall the Administrative Agent be required to take any
action which exposes the Administrative Agent to personal liability or which is
contrary to this Agreement, the Loan Documents or applicable law. If a Default
has occurred and is continuing, the Syndication Agents shall have no obligation
to perform any act in respect thereof. No Agent shall be liable for any action
taken or not taken by it with the consent or at the request of the Majority
Lenders or the Lenders (or such other number or percentage of the Lenders as
shall be necessary under the circumstances as provided in Section 12.02), and
otherwise no Agent shall be liable for any action taken or not taken by it
hereunder or under any other Loan Document or under any other document or
instrument referred to or provided for herein or therein or in connection
herewith or therewith INCLUDING

                                       54

ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful
misconduct.

         Section 11.04 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument,
document or other writing believed by it to be genuine and to have been signed
or sent by the proper Person. The Administrative Agent also may rely upon any
statement made to it orally or by telephone and believed by it to be made by the
proper Person, and shall not incur any liability for relying thereon and each of
the Borrower and the Lenders hereby waives the right to dispute the
Administrative Agent's record of such statement, except in the case of gross
negligence or willful misconduct by the Administrative Agent. The Administrative
Agent may consult with legal counsel (who may be counsel for the Borrower),
independent accountants and other experts selected by it, and shall not be
liable for any action taken or not taken by it in accordance with the advice of
any such counsel, accountants or experts. The Agents may deem and treat the
payee of any Note as the holder thereof for all purposes hereof unless and until
a written notice of the assignment or transfer thereof permitted hereunder shall
have been filed with the Administrative Agent.

         Section 11.05 Subagents. The Administrative Agent may perform any and
all its duties and exercise its rights and powers by or through any one or more
sub-agents appointed by the Administrative Agent. The Administrative Agent and
any such sub-agent may perform any and all its duties and exercise its rights
and powers through their respective Related Parties. The exculpatory provisions
of the preceding Sections of this ARTICLE XI shall apply to any such sub-agent
and to the Related Parties of the Administrative Agent and any such sub-agent,
and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities
as Administrative Agent.

         Section 11.06 Resignation or Removal of Agents. Subject to the
appointment and acceptance of a successor Agent as provided in this Section
11.06, any Agent may resign at any time by notifying the Lenders and the
Borrower, and any Agent may be removed at any time with or without cause by the
Majority Lenders. Upon any such resignation or removal, the Majority Lenders
shall have the right, in consultation with the Borrower, to appoint a successor.
If no successor shall have been so appointed by the Majority Lenders and shall
have accepted such appointment within 30 days after the retiring Agent gives
notice of its resignation or removal of the retiring Agent, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a
bank with an office in New York, New York, or an Affiliate of any such bank.
Upon the acceptance of its appointment as Agent hereunder by a successor, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Borrower to a successor Agent shall be the same as those payable to its
predecessor unless otherwise agreed between the Borrower and such successor.
After the Agent's resignation hereunder, the provisions of this ARTICLE XI and
Section 12.03 shall continue in effect for the benefit of such retiring Agent,
its sub-agents and their respective Related Parties in respect of any actions
taken or omitted to be taken by any of them while it was acting as Agent.

                                       55

<PAGE>

         Section 11.07 Agents as Lenders. Each bank serving as an Agent
hereunder shall have the same rights and powers in its capacity as a Lender as
any other Lender and may exercise the same as though it were not an Agent, and
such bank and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any other Loan
Party or other Affiliate thereof as if it were not an Agent hereunder.

         Section 11.08 No Reliance. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, any other
Agent or any other Lender and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement and each other Loan Document to which it is a party. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent, any other Agent or any other Lender and based on such
documents and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any other Loan Document, any related agreement or any
document furnished hereunder or thereunder. The Agents shall not be required to
keep themselves informed as to the performance or observance by the Borrower or
any other Loan Party of this Agreement, the Loan Documents or any other document
referred to or provided for herein or to inspect the Properties or books of the
Borrower or any other Loan Party . Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder, no Agent or the Arranger shall have any duty
or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Borrower (or any
of its Affiliates) which may come into the possession of such Agent or any of
its Affiliates. In this regard, each Lender acknowledges that Vinson & Elkins
L.L.P. is acting in this transaction as special counsel to the Administrative
Agent only, except to the extent otherwise expressly stated in any legal opinion
or any Loan Document. Each other party hereto will consult with its own legal
counsel to the extent that it deems necessary in connection with the Loan
Documents and the matters contemplated therein.

         Section 11.09 Administrative Agent May File Proofs of Claim. In case of
the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent (irrespective of
whether the principal of any Loan shall then be due and payable as herein
expressed or by declaration or otherwise and irrespective of whether the
Administrative Agent shall have made any demand on the Borrower) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

         (a) to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Loans and all other Indebtedness
that are owing and unpaid and to file such other documents as may be necessary
or advisable in order to have the claims of the Lenders and the Administrative
Agent (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Lenders and the Administrative Agent and their
respective agents and counsel and all other amounts due the Lenders and the
Administrative Agent under Section 12.03) allowed in such judicial proceeding;
and

         (b) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

                                       56

<PAGE>

         and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Lender to make such payments to the Administrative Agent and,
in the event that the Administrative Agent shall consent to the making of such
payments directly to the Lenders, to pay to the Administrative Agent any amount
due for the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Section 12.03.

         Nothing contained herein shall be deemed to authorize the
Administrative Agent to authorize or consent to or accept or adopt on behalf of
any Lender any plan of reorganization, arrangement, adjustment or composition
affecting the Indebtedness or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

         Section 11.10 Authority of Administrative Agent to Release Collateral
and Liens. Each Lender hereby authorizes the Administrative Agent to release any
collateral that is permitted to be sold or released pursuant to the terms of the
Loan Documents. Each Lender hereby authorizes the Administrative Agent to
execute and deliver to the Borrower, at the Borrower's sole cost and expense,
any and all releases of Liens, termination statements, assignments or other
documents reasonably requested by the Borrower in connection with any sale or
other disposition of Property to the extent such sale or other disposition is
permitted by the terms of Section 9.11 or is otherwise authorized by the terms
of the Loan Documents.

         Section 11.11 The Arranger and the Syndication Agents. The Arranger and
the Syndication Agents shall have no duties, responsibilities or liabilities
under this Agreement and the other Loan Documents other than their duties,
responsibilities and liabilities in their capacity as Lenders hereunder.

                                  ARTICLE XII
                                  MISCELLANEOUS

         Section 12.01 Notices.

permitted to be given by telephone (and subject to Section 12.01(b)), all
notices and other communications provided for herein shall be in writing and
shall be delivered by hand or overnight courier service, mailed by certified or
registered mail or sent by telecopy, as follows:

              (i) if to the Borrower, to it at 131 South Robertson, New Orleans,
         Louisiana 70112, Attention of John C. Higgins (Telecopy No. (504)
         561-2551);

                                       57

<PAGE>

         (b) Notices and other communications to the Lenders hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent; provided that the foregoing shall not
apply to notices pursuant to ARTICLE II, ARTICLE III, ARTICLE IV and ARTICLE V
unless otherwise agreed by the Administrative Agent and the applicable Lender.
The Administrative Agent or the Borrower may, in its discretion, agree to accept
notices and other communications to it hereunder by electronic communications
pursuant to procedures approved by it; provided that approval of such procedures
may be limited to particular notices or communications.

         (c) Any party hereto may change its address or telecopy number for
notices and other communications hereunder by notice to the other parties
hereto. All notices and other communications given to any party hereto in
accordance with the provisions of this Agreement shall be deemed to have been
given on the date of receipt.

         Section 12.02 Waivers; Amendments.

         (a) No failure on the part of the Administrative Agent or any Lender to
exercise and no delay in exercising, and no course of dealing with respect to,
any right, power or privilege, or any abandonment or discontinuance of steps to
enforce such right, power or privilege, under any of the Loan Documents shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under any of the Loan Documents preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies of the Administrative Agent and the Lenders hereunder
and under the other Loan Documents are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of
this Agreement or any other Loan Document or consent to any departure by the
Borrower therefrom shall in any event be effective unless the same shall be
permitted by Section 12.02(b), and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

         (b) Neither this Agreement nor any provision hereof nor any Security
Instrument nor any provision thereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower
and the Majority Lenders or by the Borrower and the Administrative Agent with
the consent of the Majority Lenders; provided that no such agreement shall (i)
increase the Commitment of any Lender without the written consent of such
Lender, (ii) reduce the principal amount of any Loan or reduce the rate of
interest thereon, or reduce any fees payable hereunder, or reduce any other
Indebtedness hereunder or under any other Loan Document, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment or prepayment of the principal amount of any Loan, or any interest
thereon, or any fees payable hereunder, or any other Indebtedness hereunder or
under any other Loan Document, or reduce the amount of, waive or excuse any such
payment, or postpone or extend the Termination Date without the written consent
of each Lender affected thereby, (iv) change Section 4.01(b) or Section 4.01(c)
in a manner that would alter the pro rata sharing of payments required thereby,
without the written consent of each Lender, (v) waive or amend Section 6.01,
Section 8.12, Section 10.02(c) or

                                       58

the written consent of each Lender,  (vi) release any Guarantor  (except as set
forth in the  Guarantees),  release any of the collateral  (other than as
provided in Section 11.10), without the written consent of each Lender, or (vii)
change any of the  provisions  of this Section  12.02(b) or the  definitions  of
"Majority  Lenders"  or any other  provision  hereof  specifying  the  number or
percentage of Lenders required to waive, amend or modify any rights hereunder or
under any other Loan  Documents or make any  determination  or grant any consent
hereunder  or any other Loan  Documents,  without  the  written  consent of each
Lender; provided further that no such agreement shall amend, modify or otherwise
affect the rights or duties of the  Administrative  Agent hereunder or under any
other Loan  Document  without the prior  written  consent of the  Administrative
Agent.

         Section 12.03 Expenses, Indemnity; Damage Waiver.

         (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent and its Affiliates, including, without
limitation, the reasonable fees, charges and disbursements of counsel and other
outside consultants for the Administrative Agent, the reasonable travel,
photocopy, mailing, courier, telephone and other similar expenses, and the cost
of environmental audits and surveys and appraisals, in connection with the
syndication of the credit facilities provided for herein, the preparation,
negotiation, execution, delivery and administration (both before and after the
execution hereof and including advice of counsel to the Administrative Agent as
to the rights and duties of the Administrative Agent and the Lenders with
respect thereto) of this Agreement and the other Loan Documents and any
amendments, modifications or waivers of or consents related to the provisions
hereof or thereof (whether or not the transactions contemplated hereby or
thereby shall be consummated), (ii) all reasonable costs, expenses, Taxes,
assessments and other charges incurred by any Agent or any Lender in connection
with any filing, registration, recording or perfection of any security interest

the Loans made hereunder, including, without limitation, all such reasonable
out-of-pocket expenses incurred during any workout, restructuring or

         (c) To the extent that the Borrower fails to pay any amount required to
be paid by it to any Agent under Section 12.03(a) or (b), each Lender severally
agrees to pay to such Agent such Lender's Applicable Percentage (determined as
of the time that the applicable unreimbursed expense or indemnity payment is

contemplated hereby or thereby, the Transactions, any Loan or the use of the
proceeds thereof.

         (e) All amounts due under this Section 12.03 shall be payable not later
than thirty (30) days after written demand therefor.

         Section 12.04 Successors and Assigns.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that (i) the Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by the Borrower
without such consent shall be null and void) and (ii) no Lender may assign or
otherwise transfer its rights or obligations hereunder except in accordance with
this Section 12.04. 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 Section 12.04(c)) and, to the extent expressly contemplated hereby,
the Related Parties of each of the Administrative 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 Section 12.04(b)(ii),
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 its
Commitment and the Loans at the time owing to it) with the prior written consent
(such consent not to be unreasonably withheld) of:

                (A) the Borrower, provided that no consent of the Borrower shall
be required for an assignment to a Lender, an Affiliate of a Lender, an Approved
Fund or, if an Event of Default has occurred and is continuing, any other
assignee; and

                                       61

<PAGE>

                (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) except in the case of an assignment to a Lender or an
Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment or Loans, the amount of the Commitment or Loans of
the assigning Lender subject to each such assignment (determined as of the date
the Assignment and Assumption with respect to such assignment is delivered to
the Administrative Agent) shall not be less than $2,000,000 unless each of the
Borrower and the Administrative Agent otherwise consent, provided that no such
consent of the Borrower shall be required if an Event of Default has occurred
and is continuing;

                (B) 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;

                (C) 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; and

                (D) the assignee, if it shall not be a Lender, shall deliver to
the Administrative Agent an Administrative Questionnaire.

            (iii) Subject to Section 12.04(b)(iv) and the acceptance and
         recording thereof, 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
         Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any
         assignment or transfer by a Lender of rights or obligations under this
         Agreement that does not comply with this Section 12.04 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 Section
         12.04(c).

             (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
         Commitment of, and principal amount of the Loans owing to, each Lender
         pursuant to the terms hereof from time to time (the "Register"). The
         entries in the Register shall be conclusive, and the Borrower, the
         Administrative Agent and the Lenders may treat each Person
         whose name is recorded in the Register pursuant to the

                                       62

<PAGE>

         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. In
         connection with any changes to the Register, if necessary, the
         Administrative Agent will reflect the revisions on Annex I and forward
         a copy of such revised Annex I to the Borrower and each Lender.

              (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 Section 12.04(b) and any written consent to such
         assignment required by Section 12.04(b), the Administrative Agent shall
         accept such Assignment and Assumption 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 Section 12.04(b).

         (c) (i) Any Lender may, without the consent of the Borrower or the
Administrative 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 its Commitment and the Loan
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 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; 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 the proviso to Section 12.02 that affects such Participant. In
addition such agreement must provide that the Participant be bound by the
provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower
agrees that each Participant shall be entitled to the benefits of Section 5.01,
Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to Section 12.04(b). To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 12.08 as though it were a Lender, provided such Participant agrees to be
subject to Section 4.01(c) as though it were a Lender.

                  (ii) A Participant shall not be entitled to receive any
         greater payment under Section 5.01 or Section 5.03 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 5.03
         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 5.03(e) as though it were a Lender.

                                       63

<PAGE>

         (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, without limitation, any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section 12.04(d) 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.

         (e) Notwithstanding any other provisions of this Section 12.04, no
transfer or assignment of the interests or obligations of any Lender or any
grant of participations therein shall be permitted if such transfer, assignment
or grant would require the Borrower to file a registration statement with the
SEC or to qualify the Loans under the "Blue Sky" laws of any state.

         Section 12.05 Survival; Revival; Reinstatement.

         (a) All covenants, agreements, representations and warranties made by
the Borrower herein and in the certificates or other instruments delivered in
connection with or pursuant to this Agreement or any other Loan Document shall
be considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated. The
provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and
ARTICLE XI shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Commitments or the termination of
this Agreement, any other Loan Document or any provision hereof or thereof.

         (b) To the extent that any payments on the Indebtedness or proceeds of
any collateral are subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver or other Person under any bankruptcy law, common law or
equitable cause, then to such extent, the Indebtedness so satisfied shall be
revived and continue as if such payment or proceeds had not been received and
the Administrative Agent's and the Lenders' Liens, security interests, rights,
powers and remedies under this Agreement and each Loan Document shall continue
in full force and effect. In such event, each Loan Document shall be
automatically reinstated and the Borrower shall take such action as may be
reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement.

         Section 12.06 Counterparts; Integration; Effectiveness.

                                       64

<PAGE>

         (a) This Agreement may be executed in counterparts (and by different
parties hereto on different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single
contract.

         (b) This Agreement, the other Loan Documents and any separate letter
agreements with respect to fees payable to the Administrative Agent constitute
the entire contract among the parties relating to the subject matter hereof and
thereof and supersede any and all previous agreements and understandings, oral
or written, relating to the subject matter hereof and thereof. This Agreement
and the other Loan Documents represent the final agreement among the parties
hereto and thereto and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
unwritten oral agreements between the parties.

         (c) Except as provided in Section 6.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when
taken together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

         Section 12.07 Severability. Any provision of this Agreement or any
other Loan Document held to be invalid, illegal or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability without affecting the validity,
legality and enforceability of the remaining provisions hereof or thereof; and
the invalidity of a particular provision in a particular jurisdiction shall not
invalidate such provision in any other jurisdiction.

         Section 12.08 Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations (of
whatsoever kind, including, without limitations obligations under Swap
Agreements) at any time owing by such Lender or Affiliate to or for the credit
or the account of the Borrower or any or its Affiliates against any of and all
the obligations of the Borrower or any or any of its Affiliates owed to such
Lender now or hereafter existing under this Agreement or any other Loan
Document, irrespective of whether or not such Lender shall have made any demand
under this Agreement or any other Loan Document and although such obligations
may be unmatured. The rights of each Lender under this Section 12.08 are in
addition to other rights and remedies (including other rights of setoff) which
such Lender or its Affiliates may have.

         Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

         (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW

                                       65

CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY
THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED.

         (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS
MAY BE BROUGHT 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 PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT
PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE
OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT
PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT
OTHERWISE HAVING JURISDICTION.

         (c) THE BORROWER HEREBY IRREVOCABLY DESIGNATES, APPOINTS AND EMPOWERS
AND HEREBY CONFERS AN IRREVOCABLE SPECIAL POWER, AMPLE AND SUFFICIENT, TO CT

ACTION OR PROCEEDING IN NEW YORK TO RECEIVE AND ACCEPT FOR AND ON ITS BEHALF,
AND IN RESPECT OF ITS PROPERTY, SERVICE OF ANY AND ALL LEGAL PROCESS, SUMMONS,
NOTICES AND DOCUMENTS WHICH MAY BE SERVED IN ANY SUCH PROCEEDING AND AGREES THAT
THE FAILURE OF SUCH AGENT TO GIVE ANY ADVICE OF ANY SUCH SERVICE OF PROCESS TO
THE BORROWER SHALL NOT IMPAIR OR AFFECT THE VALIDITY OF SUCH SERVICE OR OF ANY
CLAIM BASED THEREON. IF FOR ANY REASON SUCH DESIGNEE, APPOINTEE AND AGENT SHALL
CEASE TO BE AVAILABLE TO ACT AS SUCH, THE BORROWER AGREES TO DESIGNATE A NEW
DESIGNEE, APPOINTEE AND AGENT IN NEW YORK CITY REASONABLY SATISFACTORY TO THE
ADMINISTRATIVE AGENT ON THE TERMS AND FOR THE PURPOSES OF THIS PROVISION. EACH
PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE

RIGHT OF A PARTY 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
ANOTHER PARTY IN ANY OTHER JURISDICTION.

                                       66

         (d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO

         Section 12.10 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

         Section 12.11 Confidentiality. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
shall agree to be bound by the terms of this Section 12.11), (b) to the extent
requested by any regulatory authority having jurisdiction over such Person, (c)
to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement or any other
Loan Document, (e) in connection with the exercise of any remedies hereunder or
under any other Loan Document or any suit, action or proceeding relating to this
Agreement or any other Loan Document or the enforcement of rights hereunder or
thereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section 12.11, to (i) any assignee of or Participant in,
or any prospective assignee of or Participant in, any of its rights or
obligations under this Agreement or (ii) any actual or prospective counterparty
(or its advisors) to any Swap Agreement relating to the Borrower and its
obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section 12.11 or (ii) becomes available to the Administrative Agent or any
Lender on a nonconfidential basis from a source other than the Borrower. For the
purposes of this Section 12.11, "Information" means all information received
from the Borrower or any other Loan Party relating to the Borrower or any other
Loan Party and their businesses, other than any such information that is
available to the Administrative Agent or any Lender on a nonconfidential basis
prior to disclosure by the Borrower or any other Loan Party; provided that, in
the case of information received from the Borrower or other Loan Party after the
date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section 12.11 shall be considered to have complied with its

                                       67

<PAGE>

obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information. Notwithstanding anything herein to the
contrary, "Information" shall not include, and the Borrower, the other Loan
Parties, the Administrative Agent, each Lender and the respective Affiliates of
each of the foregoing (and the respective partners, directors, officers,
employees, agents, advisors and other representatives of the aforementioned
Persons), and any other party, may disclose to any and all Persons, without
limitation of any kind (a) any information with respect to the U.S. federal and
state income tax treatment of the transactions contemplated hereby and any facts
that may be relevant to understanding the U.S. federal or state income tax
treatment of such transactions ("tax structure"), which facts shall not include
for this purpose the names of the parties or any other person named herein, or
information that would permit identification of the parties or such other
persons, or any pricing terms or other nonpublic business or financial
information that is unrelated to such tax treatment or tax structure, and (b)
all materials of any kind (including opinions or other tax analyses) that are
provided to the Borrower, the Administrative Agent or such Lender relating to
such tax treatment or tax structure.

         Section 12.12 Interest Rate Limitation. It is the intention of the
parties hereto that each Lender shall conform strictly to usury laws applicable
to it. Accordingly, if the transactions contemplated hereby would be usurious as
to any Lender under laws applicable to it (including the laws of the United
States of America and the State of Texas or any other jurisdiction whose laws
may be mandatorily applicable to such Lender notwithstanding the other
provisions of this Agreement), then, in that event, notwithstanding anything to
the contrary in any of the Loan Documents or any agreement entered into in
connection with or as security for the Notes, it is agreed as follows: (i) the
aggregate of all consideration which constitutes interest under law applicable
to any Lender that is contracted for, taken, reserved, charged or received by
such Lender under any of the Loan Documents or agreements or otherwise in
connection with the Notes shall under no circumstances exceed the maximum amount
allowed by such applicable law, and any excess shall be canceled automatically
and if theretofore paid shall be credited by such Lender on the principal amount
of the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such
Lender to the Borrower); and (ii) in the event that the maturity of the Notes is
accelerated by reason of an election of the holder thereof resulting from any
Event of Default under this Agreement or otherwise, or in the event of any
required or permitted prepayment, then such consideration that constitutes
interest under law applicable to any Lender may never include more than the
maximum amount allowed by such applicable law, and excess interest, if any,
provided for in this Agreement or otherwise shall be canceled automatically by
such Lender as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited by such Lender on the principal amount of
the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such
Lender to the Borrower). All sums paid or agreed to be paid to any Lender for
the use, forbearance or detention of sums due hereunder shall, to the extent
permitted by law applicable to such Lender, be amortized, prorated, allocated
and spread throughout the stated term of the Loans evidenced by the Notes until
payment in full so that the rate or amount of interest on account of any Loans
hereunder does not exceed the maximum amount allowed by such applicable law. If
at any time and from time to time (i) the amount of interest payable to any
Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Lender pursuant to this Section 12.12

                                       68

and (ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to such Lender would be less than the amount of
interest payable to such Lender computed at the Highest Lawful Rate applicable
to such Lender, then the amount of interest payable to such Lender in respect of
such subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to such Lender until the total amount of interest
payable to such Lender shall equal the total amount of interest which would have
been payable to such Lender if the total amount of interest had been computed
without giving effect to this Section 12.12. To the extent that Chapter 303 of
the Texas Finance Code is relevant for the purpose of determining the Highest
Lawful Rate applicable to a Lender, such Lender elects to determine the
applicable rate ceiling under such Chapter by the weekly ceiling from time to
time in effect. Chapter 346 of the Texas Finance Code does not apply to the
Borrower's obligations hereunder.

         Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS
AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS,
CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY
INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING
ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED
THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

         Section 12.14 Collateral Matters; Swap Agreements. The benefit of the
Security Instruments and of the provisions of this Agreement relating to any
collateral securing the Indebtedness shall also extend to and be available to
those Lenders or their Affiliates which are counterparties to any Secured Swap
Agreement with the Borrower, subject to Section 10.02(c), on a pro rata basis in
respect of any obligations of the Borrower which arise under any such Secured
Swap Agreement while such Person or its Affiliate is a Lender, but only while
such Person or its Affiliate is a Lender, including any Secured Swap Agreements
between such Persons in existence prior to the date hereof. No Lender or any
Affiliate of a Lender shall have any voting rights under any Loan Document as a
result of the existence of obligations owed to it under any such Secured Swap
Agreements.

         Section 12.15 No Third Party Beneficiaries. This Agreement, the other
Loan Documents, and the agreement of the Lenders to make Loans hereunder are
solely for the benefit

                                       69

of the Borrower, and no other Person (including, without limitation, any other
Loan Party, any obligor, contractor, subcontractor, supplier or materialsman)
shall have any rights, claims, remedies or privileges hereunder or under any
other Loan Document against the Administrative Agent, any other Agent or any
Lender for any reason whatsoever. There are no third party beneficiaries.
