      paragraph (ii) above, the Accountants will provide prior to December 31,
      2005, a letter in form and substance satisfactory to the Owner Trustee if
      any tax withholding is then required and the procedures to be followed
      with respect thereto to comply with the requirements of the Code. The
      Accountants shall be required to update the letter in each instance that
      any additional tax withholding is subsequently required or any previously
      required tax withholding shall no longer be required.

      Administrator under the Trust Agreement.

            (vi)  In carrying out the foregoing duties or any of its other
      obligations under this Agreement, the Administrator may enter into
      transactions or otherwise deal with any of its Affiliates; provided,
      however, that the terms of any such transactions or dealings shall be in
      accordance with any directions received from the Issuer and shall be, in
      the Administrator's opinion, no less favorable to the Issuer than would be
      available from unaffiliated parties.

      (c)   Non-Ministerial Matters.

            (i)   With respect to matters that in the reasonable judgment of the
      Administrator are non-ministerial, the Administrator shall not take any
      action unless within a reasonable time before the taking of such action,
      the Administrator shall have notified the Owner Trustee of the proposed
      action and the Owner Trustee shall not have withheld consent or provided
      an alternative direction. For the purpose of the preceding sentence,

            Indenture or the appointment of successor Administrators or a
            successor Master Servicer, or the consent to the assignment by any
            of the Note Registrar, the Paying Agent or the Indenture Trustee of
            its obligations under the Indenture; and

                  (E)   the removal of the Indenture Trustee.

            (ii)  Notwithstanding anything to the contrary in this Agreement,
      the Administrator shall not be obligated to, and shall not, (A) make any
      payments to the Noteholders under the Related Agreements, (B) take any
      other action that the Issuer directs the Administrator not to take on its
      behalf or (C) take any other action which may be construed as having the
      effect of varying the investment of the Holders.

Company at any time during normal business hours.

Administrator's obligations under this Agreement and as reimbursement for its
expenses related thereto, the Administrator shall be entitled to an annual
payment of compensation which shall be solely an obligation of the Company.

      Section 4. Additional Information to be Furnished to the Issuer. The
Administrator shall furnish to the Issuer from time to time such additional
information regarding the Collateral as the Issuer shall reasonably request.

      Section 5. Independence of the Administrator. For all purposes of this
Agreement, the Administrator shall be an independent contractor and shall not be
subject to the supervision of the Issuer or the Owner Trustee with respect to
the manner in which it accomplishes the performance of its obligations
hereunder. Unless expressly authorized by the Issuer, the Administrator shall
have no authority to act for or represent the Issuer or the Owner Trustee in any
way and shall not otherwise be deemed an agent of the Issuer or the Owner
Trustee.

      Section 6. No Joint Venture. Nothing contained in this Agreement shall (i)
constitute the Administrator and either of the Issuer or the Owner Trustee as
members of any partnership, joint venture, association, syndicate,
unincorporated business or other separate entity, (ii) be construed to impose
any liability as such on any of them or (iii) be deemed to confer on any of them
any express, implied or apparent authority to incur any obligation or liability
on behalf of the others.

      Section 7. Other Activities of Administrator. Nothing herein shall prevent
the Administrator or its Affiliates from engaging in other businesses or, in its
sole discretion, from acting in a similar capacity as an administrator for any
other Person or entity even though such person or entity may engage in business
activities similar to those of the Issuer, the Owner Trustee or the Indenture
Trustee.

            (i)   the Administrator shall default in the performance of any of
      its duties under this Agreement and, after notice of such default, shall
      not cure such default within ten days (or, if such default cannot be cured
      in such time, shall not give within ten days such assurance of cure as
      shall be reasonably satisfactory to the Issuer);

                                       8

            (ii)  a court having jurisdiction in the premises shall enter a

      custodian, trustee, sequestrator or similar official for the Administrator

      involuntary case under any such law, or shall consent to the appointment
      of a receiver, liquidator, assignee, trustee, custodian, sequestrator or
      similar official for the Administrator or any substantial part of its
      property, shall consent to the taking of possession by any such official
      of any substantial part of its property, shall make any general assignment
      for the benefit of creditors or shall fail generally to pay its debts as
      they become due.

      The Administrator agrees that if any of the events specified in clauses
(ii) or (iii) above shall occur, it shall give written notice thereof to the
Issuer and the Indenture Trustee within seven days after the occurrence of such
event.

      (d)   No resignation or removal of the Administrator pursuant to this
Section shall be effective until (i) a successor Administrator shall have been
appointed by the Issuer and (ii) such successor Administrator shall have agreed
in writing to be bound by the terms of this Agreement in the same manner as the
Administrator is bound hereunder.

      (e)   The appointment of any successor Administrator shall be effective
only after satisfaction of the Rating Agency Condition with respect to the
proposed appointment.

      (f)   Subject to Sections 8(d) and 8(e), the Administrator acknowledges

and Servicing Agreement, the Administrator shall immediately resign and such

Collateral then in the custody of the Administrator. In the event of the
resignation or removal of the Administrator pursuant to Section 8(a), (b) or
(c), respectively, the Administrator shall cooperate with the Issuer and take
all reasonable steps requested to assist the Issuer in making an orderly
transfer of the duties of the Administrator.

to the address of such party as provided above.

      Section 11. Amendments. This Agreement may be amended from time to time by
a written amendment duly executed and delivered by the parties hereto, with the
written consent of the Owner Trustee but without the consent of the Noteholders
and the Certificateholders, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Noteholders or Certificateholders;
provided that such amendment will not, in the Opinion of Counsel satisfactory to
the Indenture Trustee, materially and adversely affect the interest of any
Noteholder or Certificateholder. This Agreement may also be amended by the
parties hereto with the written consent of the Owner Trustee and the holders of
Notes evidencing at least a majority of the Outstanding Amount of the Notes and
the holders of Certificates evidencing at least a majority of the Certificate
Percentage for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of Noteholders or the Certificateholders; provided, however,
that no such amendment may (i) increase or reduce in any manner the amount of,
or accelerate or delay the timing of, collections of payments on the Contracts

or Certificateholders or (ii) reduce the aforesaid percentage of the holders of

Notwithstanding the foregoing, the Administrator may not amend this Agreement
without the permission of the Seller, which permission shall not be unreasonably
withheld.

      Section 12. Successors and Assigns. This Agreement may not be assigned by

by the Issuer and the Owner Trustee and subject to the satisfaction of the
Rating Agency Condition in respect thereof. An assignment with such consent and
satisfaction, if accepted by the assignee, shall bind the assignee hereunder in
the same manner as the Administrator is bound hereunder. Notwithstanding the
foregoing, this Agreement may be assigned by the Administrator without the
consent of the Issuer or the Owner Trustee to a corporation or other
organization that is a successor (by merger, consolidation or purchase of
assets) to the Administrator; provided that such successor organization executes
and delivers to the Issuer, the Owner Trustee and the Indenture Trustee an
agreement, in form and substance reasonably satisfactory to the Owner Trustee
and the Indenture Trustee, in which such corporation or other organization
agrees to be bound hereunder by the terms of said assignment in the same manner

special, punitive or consequential loss or damage of any kind whatsoever,
including lost profits, even if the Indenture Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action.

     SECTION 2.1 Facility. The Lenders grant to the Borrower a credit facility (the
“Facility”) pursuant to which, and upon the terms and subject to the conditions herein set
out and provided that no Default or Event of Default has occurred and is continuing from time to
time on any Business Day, each Lender severally agrees to make Loans in U.S. Dollars to the
Borrower equal to such Lender’s Percentage of the aggregate amount of Loans requested by the
Borrower to be made on such day.

     SECTION 2.1.1 Loans. From time to time on or after the date hereof and prior to the
Maturity Date, each Lender shall make Loans under this Section to the Borrower in an aggregate
principal amount at any one time outstanding up to but not exceeding such Lender’s Commitment.
Subject to the conditions herein, any such Loan repaid prior to the Maturity Date may be reborrowed
pursuant to the terms of this Agreement.

     SECTION 2.1.2 Availability of Facility. No Lender shall be permitted or required to
make (i) any Loan if, after giving effect thereto, the aggregate outstanding principal amount of
all Loans of all Lenders would exceed the Commitment Amount, or (ii) any Loan if, after giving
effect thereto, the aggregate amount of all Loans of such Lender would exceed the Lender’s
Percentage of the Commitment Amount.

     SECTION 2.2 Mandatory Reductions of Commitment Amount.

     SECTION 2.2.1 On Maturity Date. The Commitment Amount shall be reduced automatically
to zero ($0), and all Commitments of the Lenders shall be automatically terminated, on the Maturity

the pro rata portion of the Commitment of each Lender, shall be reduced as follows:

     (a) on (A) the last day of each Fiscal Quarter ending June 2008, September 2008, December
2008, and March 2009 by an amount equal to five percent (5%) of the Commitment Amount existing on

fair market value in excess of $25,000,000, on the fifth (5th) Business Day after the receipt of
any Excess Sale Proceeds, and (ii) in the case of an Asset Sale having a fair market value not in
excess of $25,000,000, on the last day of the Fiscal Quarter in which any Excess Sale Proceeds are
received; and

transaction costs incurred in connection therewith, of any issuance on or after the

time on any Business Day occurring after the Effective Date, voluntarily reduce the amount of the

least three Business Days’ prior notice to the Administrative Agent and be permanent, and any
partial reduction of the Commitment Amount shall be in a minimum amount of $10,000,000 and in an
integral multiple of $1,000,000; and provided further that the Borrower shall not

     SECTION 2.4 Base Rate Loans and Eurodollar Loans. Subject to the terms and conditions
set forth in Article V, each Loan shall be either a Eurodollar Loan or a Base Rate Loan as
the Borrower may request, it being understood that Loans made to the Borrower on any date may be

each Lender may, if it so elects, fulfill its commitment to make such Eurodollar Loan by causing
its Eurodollar Office to make such Eurodollar Loan; provided, however, that in such
event the obligation of the Borrower to repay such Eurodollar Loan nevertheless shall be to such
Lender and shall be deemed to be held by such Lender for the account of such Eurodollar Office.

     SECTION 2.5 Borrowing Procedures for Loans. The Borrower shall give the
Administrative Agent prior written or telegraphic notice pursuant to a Borrowing Request (in
substantially the form of Exhibit 2.5 hereto) of each proposed Borrowing or continuation,

$5,000,000 and an integral multiple of $1,000,000), and the Administrative Agent shall advise each
Lender thereof promptly thereafter. Not later than 10:00 a.m., Central time, on the date specified
in such notice for such Borrowing, each Lender shall provide to the Administrative Agent at the
Payment Office, same day or immediately available funds covering such Lender’s Percentage of the
requested Base Rate Loan. Upon fulfillment of the applicable conditions set forth in Article
V with respect to such Base Rate Loan, the Administrative Agent shall make available to the
Borrower the proceeds of each Base Rate Loan (to the extent received from the Lenders) by wire
transfer of such proceeds to such account(s) as the Borrower shall have specified in the Borrowing
Request.

16

 

     SECTION 2.5.2 Eurodollar Loans. The Administrative Agent shall receive written or
telegraphic notice pursuant to a Borrowing Request from the Borrower on or before 10:00 a.m.
Central time, at least three (3) Business Days prior to the date requested for each proposed

the case may be, the amount of such Borrowing or continuation, as the case may be (which shall be
in a minimum amount of $5,000,000 and an integral multiple of $1,000,000), and the duration of the
initial Eurodollar Interest Period with respect thereto, and the Administrative Agent shall advise
each Lender thereof promptly thereafter. Not later than 10:00 a.m., Central time, on the date
specified in such notice for such Borrowing, each Lender shall provide to the Administrative Agent
at the Payment Office, same day or immediately available funds covering such Lender’s Percentage of
the requested Eurodollar Loan. Upon fulfillment of the applicable conditions set forth in
Article V with respect to such Eurodollar Loan, the Administrative Agent shall make
available to the Borrower the proceeds of each Eurodollar Loan (to the extent received from the
Lenders) by wire transfer of such proceeds to such account(s) as the Borrower shall have specified
in the Borrowing Request.

     SECTION 2.6 Continuation and Conversion Elections. By delivering a
Continuation/Conversion Notice to the Administrative Agent on or before 10:00 a.m., Central time,
on a Business Day, the Borrower may from time to time irrevocably elect, on not less than three (3)
nor more than five (5) Business Days’ notice that all, or any portion in an aggregate minimum
amount of $5,000,000 and an integral multiple of $1,000,000 of any Borrowings be, (i) in the case
of Base Rate Loans, converted into Eurodollar Loans, or (ii) in the case of Eurodollar Loans, be
converted into a Base Rate Loan or continued as a Eurodollar Loan of such Type (in the absence of
delivery of a Continuation/Conversion Notice with respect to any Eurodollar Loan at least three (3)
Business Days before the last day of the then current Interest Period with respect thereto, such
Eurodollar Loan shall, on such last day, automatically convert to a Base Rate Loan);
provided, however, that (i) each such conversion or continuation shall be pro rated
among the applicable outstanding Loans of all Lenders, and (ii) no portion of the outstanding
principal amount of any Loans may be continued as, or be converted into, Eurodollar Loans when any
Default has occurred and is continuing.

     SECTION 2.7 Funding. Each Lender may, if it so elects, fulfill its obligation to
make, continue or convert Eurodollar Loans hereunder by causing one of its foreign branches or
Affiliates (or an international banking facility created by such Lender) to make or maintain such
Eurodollar Loan; provided, however, that such Eurodollar Loan shall nonetheless be
deemed to have been made and to be held by such Lender, and the obligation of the Borrower to repay
such Eurodollar Loan shall nevertheless be to such Lender for the account of such foreign branch,
Affiliate or international banking facility. In addition, the Borrower hereby consents and agrees
that, for purposes of any determination to be made for purposes of Sections 4.1,
4.2, 4.3 or 4.4, it shall be conclusively assumed that each Lender elected
to fund all Eurodollar Loans by purchasing, as the case may be, Dollar deposits in its Eurodollar
Office’s interbank eurodollar market.

17

 

     SECTION 2.8 Repayment of Loans; Evidence of Debt.

     (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each Loan on the Maturity Date.

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

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

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

     (e) Any Lender may request that Loans made by it be evidenced by a promissory note, in
substantially the form attached as Exhibit 2.8 hereto. In such event, the Borrower shall
prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender
(or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved
by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest
thereon shall at all times (including after assignment pursuant to Section 10.10.1) be
represented by one or more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its registered
assigns).

ARTICLE III

principal amount of each Loan on the Maturity Date. Prior thereto, the Borrower

any such prepayment shall be applied to the Lenders among Loans having the same Type and, if
applicable, having the same Interest Period; (ii) all such voluntary prepayments shall require at

Quarterly Payment Date thereafter and on the Maturity Date.

     SECTION 3.3.2 Ticking Fee. The Borrower agrees to pay to the Administrative Agent for
the account of each Lender a commitment fee for the period from the Effective Date to, but not

ARTICLE IV

CERTAIN EURODOLLAR AND OTHER PROVISIONS

     SECTION 4.1 Eurodollar Lending Unlawful. If any Lender shall determine (which
determination shall, upon notice thereof to the Borrower and the Lenders, be conclusive and binding
on the Borrower) that the introduction of or any change in or in the interpretation of any law
makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful,
for such Lender to make, continue or maintain any Borrowing as, or to convert any Borrowing into, a
Eurodollar Borrowing, the obligations of such Lender to make, continue, maintain or convert any
such Borrowings shall, upon such determination, forthwith be suspended until such Lender shall
notify the Administrative Agent that the circumstances causing such suspension no longer exist, and
all Eurodollar Borrowings shall automatically convert into Base Rate Loans at the end of the then
current Interest Periods with respect thereto or sooner, if required by such law or assertion;
provided, however, that the obligation of such Lender to make, continue, maintain
or convert any such Eurodollar Borrowings shall remain unaffected if such Lender can designate a
different Eurodollar Office for the making, continuance, maintenance or conversion of Eurodollar
Borrowings and such designation will not, in the sole discretion of such Lender, be otherwise
disadvantageous to such Lender.

     SECTION 4.2 Deposits Unavailable or Eurodollar Interest Rate Unascertainable. If the
Administrative Agent shall have determined that, by reason of circumstances affecting the
Administrative Agent’s relevant market, adequate means do not exist for ascertaining the interest
rate applicable hereunder to Eurodollar Borrowings, then, upon notice from the Administrative Agent
to the Borrower and the Lenders, the obligations of all Lenders under Section 2.5.2 and
Section 2.6 to make or continue any Borrowings as, or to convert any Borrowings into,

20

 

Eurodollar Borrowings shall forthwith be suspended until the Administrative Agent shall notify
the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

     SECTION 4.3 Increased Eurodollar Borrowing Costs, etc. The Borrower agrees to
reimburse each Lender for any increase in the cost to such Lender of, or any reduction in the
amount of any sum receivable by such Lender in respect of, making, continuing or maintaining (or of
its obligation to make, continue or maintain) any Borrowings as, or of converting (or of its
obligation to convert) any Borrowings into, Eurodollar Borrowings. Such Lender shall promptly
notify the Administrative Agent and the Borrower in writing of the occurrence of any such event,
such notice to state, in reasonable detail, the reasons therefor and the additional amount required
fully to compensate such Lender for such increased cost or reduced amount; provided,
however, that such Lender shall designate a different Eurodollar Office if such designation
will avoid the need for, or reduce the amount of, such compensation and will not, in the sole
discretion of such Lender, be otherwise disadvantageous to such Lender. Such additional amounts
shall be payable by the Borrower directly to such Lender within fifteen days of its receipt of such
notice, and such notice shall be rebuttable presumptive evidence of the amount payable by the
Borrower.

     SECTION 4.4 Funding Losses. In the event any Lender shall incur any loss or expense
(including any loss or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to make, continue or maintain any portion of the principal
amount of any Borrowing as, or to convert any portion of the principal amount of any Borrowing
into, a Eurodollar Borrowing) as a result of (a) any conversion or repayment or prepayment of the
principal amount of any Eurodollar Borrowings on a date other than the scheduled last day of the
Interest Period applicable thereto, whether pursuant to Section 3.1 or otherwise, (b) any
Borrowings not being made as Eurodollar Borrowings in accordance with the Borrowing Request
therefor, (c) any Borrowings not being continued as, or converted into, Eurodollar Borrowings in
accordance with the Continuation/Conversion Notice, or (d) the assignment of any Eurodollar
Borrowing other than on the last day of the Interest Period applicable thereto as a result of a
request by the Borrower pursuant to Section 4.10, then, upon the written notice of such
Lender to the Borrower (with a copy to the Administrative Agent), the Borrower shall, within
fifteen days of its receipt thereof, pay directly to such Lender such amount as will (in the
reasonable determination of such Lender) reimburse such Lender for such loss or expense. Such
written notice (which shall include calculations in reasonable detail) shall be rebuttable
presumptive evidence of the amount payable by the Borrower.

     SECTION 4.5 Increased Capital Costs. If any change in, or the introduction, adoption,
effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive,
guideline, decision or request (whether or not having the force of law) of any court, central bank,
regulator or other governmental authority affects or would affect the amount of capital required or
expected to be maintained by any Lender or any Person controlling such Lender, and such Lender
determines (in its sole discretion) that the rate of return on its or such controlling Person’s
capital as a consequence of its Commitments or the Borrowings made by such Lender is reduced to a
level below that which such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from time to time by such
Lender to the Borrower, the Borrower shall pay directly to such Lender, within fifteen days,
additional amounts sufficient to compensate such Lender or such controlling Person for such
reduction in rate of return; provided, however, that such Lender shall

21

 

designate a different Domestic or Eurodollar Office if such designation will avoid the need
for, or reduce the amount of, such compensation and will not, in the sole discretion of such
Lender, be otherwise disadvantageous to such Lender. A statement of such Lender as to any such
additional amount or amounts (including calculations thereof in reasonable detail) shall be
rebuttable presumptive evidence of the amount payable by the Borrower. In determining such amount,
such Lender may use any reasonable method of averaging and attribution that it (in its sole
discretion) shall deem applicable.

     SECTION 4.6 Taxes. All payments by the Borrower of principal of, and interest on, the
Borrowings and all other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees,
duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but
excluding franchise taxes and taxes imposed on or measured by any Lender’s net income or receipts
(such non-excluded items being called “Taxes”). In the event that any withholding or
deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes
pursuant to any applicable law, rule or regulation, then the Borrower will, within fifteen days (a)
pay directly to the relevant authority the full amount required to be so withheld or deducted; (b)
promptly forward to the Administrative Agent an official receipt or other documentation
satisfactory to the Administrative Agent evidencing such payment to such authority; and (c) pay to
the Administrative Agent for the account of the Lenders such additional amount or amounts as is
necessary to ensure that the net amount actually received by each Lender will equal the full amount
such Lender would have received had no such withholding or deduction been required.

     If any Taxes are directly asserted against the Administrative Agent or any Lender with respect
to any payment received by the Administrative Agent or such Lender hereunder, the Administrative
Agent or such Lender may pay such Taxes and the Borrower will promptly pay such additional amounts
(including any penalties, interest or expenses) as is necessary in order that the net amount
received by such person after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount such person would have received had not such Taxes been asserted;
provided that the Borrower will not be obligated to pay such additional amounts to the
Administrative Agent or such Lender to the extent that such additional amounts shall have been
incurred as a consequence of the Administrative Agent’s or such Lender’s gross negligence or
willful misconduct, as the case may be.

     If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails
to remit to the Administrative Agent, for the account of the respective Lenders, the required
receipts or other required documentary evidence, the Borrower shall indemnify the Lenders for any
incremental Taxes, interest or penalties that may become payable by any Lender as a result of any
such failure. For purposes of this Section, a distribution hereunder by the Administrative Agent
or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower.

     Each Lender that is organized under the laws of a jurisdiction other than the United States
shall, prior to the due date of any payments of the Loans under this Agreement, execute and deliver
to the Borrower and the Administrative Agent, on or about the first scheduled Payment Date in each
Fiscal Year, one or more (as the Borrower or the Administrative Agent may

22

 

reasonably request) United States Internal Revenue Service Form W-8 BEN or Form W-8 ECI or
such other forms or documents (or successor forms or documents), appropriately completed, as may be
applicable to establish the extent, if any, to which a payment to such Lender is exempt from
withholding or deduction of Taxes, and shall (but only so long as such Lender remains lawfully able
to do so) deliver to the Borrower and the Administrative Agent additional copies of such forms on
or before the date that such forms expire or become obsolete or after the occurrence of an event
requiring a change in the most recent form so delivered by it and such amendments thereto as may be
reasonably requested by the Borrower or the Administrative Agent, in each case certifying that such
Lender is entitled to benefits under an income tax treaty to which the United States is a party
which reduces the rate of withholding tax on payments of interest or fees or certifying that the
income receivable pursuant to this Agreement is effectively connected with the conduct of a trade
or business in the United States. If the form provided by a Lender at the time such Lender first
becomes a party to this Agreement indicates a United States withholding tax rate in excess of zero,
withholding tax at such rate shall be considered excluded from the definition of “Taxes”. For any
period with respect to which a Lender has failed to provide the Borrower and the Administrative
Agent with the forms required pursuant to this paragraph, if any (other than if such failure is due
to a change in treaty, law or regulation occurring subsequent to the date on which a form
originally was required to be provided), such Lender shall not be entitled to indemnification under
this Section with respect to Taxes imposed by the United States which Taxes would not have been
imposed but for such failure to provide such form; provided, however, that should a Lender, which
is otherwise exempt from or subject to a reduced rate of withholding tax, become subject to Taxes
because of its failure to deliver a form required hereunder, the Borrower shall take such steps as
the Lender shall reasonably request to assist the Lender to recover such Taxes.

     If the Borrower is required to pay additional amounts to or for the account of any Lender
pursuant to this Section, then such Lender will change the jurisdiction of its applicable
Eurodollar or Domestic Office so as to eliminate or reduce any such additional payment which may
thereafter accrue if such change, in the sole discretion of such Lender, is not otherwise
disadvantageous to such Lender. No Lender shall be entitled to receive any greater payment under
this Section as a result of the designation by such Lender of a different applicable Eurodollar or
Domestic Office after the date hereof, unless such designation is made with the Borrower’s prior
written consent or by reason of the provisions of Sections 4.1, 4.3 or 4.5
requiring such Lender to designate a different applicable Eurodollar or Domestic Office under
certain circumstances or at a time when the circumstances giving rise to such greater payment did
not exist.

     SECTION 4.7 Special Fees in Respect of Reserve Requirements. With respect to
Eurodollar Borrowings, the Borrower agrees to pay to each Lender on appropriate Payment Dates, as
additional interest, such amounts as will compensate such Lender for any cost to such Lender, from
time to time, of any reserve, special deposit, special assessment or similar capital requirements
against assets of, deposits with or for the account of, or credit extended by, such Lender which
are imposed on, or deemed applicable by, such Lender, from time to time, under or pursuant to (i)
any Law, treaty, regulation or directive now or hereafter in effect (including, without limitation,
Regulation D of the Board of Governors of the Federal Reserve System but excluding any reserve
requirement included in the definition of Eurodollar Rate in Section 1.1), (ii) any
interpretation or application thereof by any governmental authority, agency or

23

 

instrumentality charged with the administration thereof or by any court, central bank or other
fiscal, monetary or other authority having jurisdiction over the Eurodollar Borrowings or the
office of such Lender where its Eurodollar Borrowings are lodged, or (iii) any requirement imposed
or requested by any court, governmental authority, agency or instrumentality or central bank,
fiscal, monetary or other authority, whether or not having the force of law. A written notice as
to the amount of any such cost or any change therein (including calculations, in reasonable detail,
showing how such Lender computed such cost or change) shall be promptly furnished by such Lender to
the Borrower and shall be rebuttable presumptive evidence of such cost or change. The Borrower
will not be responsible for paying any amounts pursuant to this Section accruing prior to 180 days
prior to the receipt by the Borrower of the written notice referred to in the preceding sentence.
Within fifteen (15) days after such certificate is furnished to the Borrower, the Borrower will pay
directly to such Lender such additional amount or amounts as will compensate such Lender for such
cost or change.

     SECTION 4.8 Payments, Computations, etc. Unless otherwise expressly provided, all
payments by the Borrower pursuant to this Agreement or any other Loan Document shall be made by the
Borrower to the Administrative Agent for the pro rata account of the Lenders
entitled to receive such payment. All such payments required to be made to the Administrative
Agent shall be made, without setoff, deduction or counterclaim, not later than 11:00 a.m., Central
time, on the date due, in same day or immediately available funds, to such account as the
Administrative Agent shall specify from time to time by notice to the Borrower. Funds received
after that time shall be deemed to have been received by the Administrative Agent on the next
succeeding Business Day. The Administrative Agent shall promptly remit in same day funds to each
Lender its share, if any, of such payments received by the Administrative Agent for the account of
such Lender. All interest and fees shall be computed on the basis of the actual number of days
(including the first day but excluding the last day) occurring during the period for which such
interest or fee is payable over a year comprised of 360 days (or, in the case of interest on a Base
Rate Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as otherwise required by
clause (c) of the definition of the term “Interest Period” with respect to
Eurodollar Loans) be made on the next succeeding Business Day and such extension of time shall be
included in computing interest and fees, if any, in connection with such payment.

     SECTION 4.9 Sharing of Payments. If any Lender shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of any
Loan (other than pursuant to the terms of Sections 4.3, 4.4 and 4.5) in
excess of its pro rata share of payments then or therewith obtained by all Lenders,
such Lender shall purchase from the other Lenders such participations in Loans made by them as
shall be necessary to cause such purchasing Lender to share the excess payment or other recovery
ratably with each of them; provided, however, that if all or any portion of the
excess payment or other recovery is thereafter recovered from such purchasing Lender, the purchase
shall be rescinded and each Lender which has sold a participation to the purchasing Lender shall
repay to the purchasing Lender the purchase price to the ratable extent of such recovery together
with an amount equal to such selling Lender’s ratable share (according to the proportion of (a) the
amount of such selling Lender’s required repayment to the purchasing Lender to (b) the
total amount so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees
that any Lender so purchasing

24

 

a participation from another Lender pursuant to this Section may, to the fullest extent
permitted by law, exercise all its rights of payment with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such participation. If
under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured
claim in lieu of a set off to which this Section applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner consistent with the
rights of the Lenders entitled under this Section to share in the benefits of any recovery on such
secured claim.

     SECTION 4.10 Replacement of Lender on Account of Increased Costs, Eurodollar Lending
Unlawful, Reserve Requirements, Taxes, Certain Dissents, etc. If any Lender shall claim the
inability to make or maintain Eurodollar Borrowings pursuant to Section 4.1 above, if any
Lender is owed increased costs under Section 4.5 above, if any payment to any Lender by the
Borrower is subject to any withholding tax pursuant to Section 4.6 above, or if any Lender
is owed any cost or expense pursuant to Section 4.7 above, the Borrower shall have the
right, if no Event of Default or Default then exists, to replace such Lender with another bank or
financial institution provided that (i) if it is not a Lender or an Affiliate thereof, such
bank or financial institution shall be reasonably acceptable to the Administrative Agent and (ii)
such bank or financial institution shall unconditionally purchase, in accordance with Section
10.10 hereof, all of such Lender’s rights and obligations under this Agreement and the other
Loan Documents and the appropriate pro rata share of such Lender’s Loans and Commitments, without
recourse or expense to, or warranty by, such Lender being replaced for a purchase price equal to
the aggregate outstanding principal amount of the Loans payable to such Lender, plus any
accrued but unpaid interest on such Loans, plus accrued but unpaid fees in respect of such Lender’s
Borrowings and Percentage of the Commitments hereunder to the date of such purchase on a date
therein specified. The Borrower shall be obligated to pay, simultaneously with such purchase and
sale, the increased costs, amounts, expenses and taxes under Sections 4.1, 4.5,
4.6, and 4.7 above, any amounts payable under Section 4.4 and all other
costs, fees and expenses payable to such Lender hereunder and under the Loan Documents, to the date
of such purchase as well as all other Obligations due and payable to or for the benefit of such
Lender; provided, that if such bank or financial institution fails to purchase such rights
and obligations, the Borrower shall continue to be obligated to pay the increased costs, amounts,
expenses and taxes under Sections 4.1, 4.5, 4.6, and 4.7 above to
such Lender.

     SECTION 4.11 Maximum Interest. It is the intention of the parties hereto to conform
strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the
obligations of the Borrower to the Administrative Agent and each Lender under this Agreement shall
be subject to the limitation that payments of interest shall not be required to the extent that
receipt thereof would be contrary to provisions of law applicable to the Administrative Agent or
such Lender limiting rates of interest which may be charged or collected by the Administrative
Agent or such Lender. Accordingly, if the transactions contemplated hereby would be usurious under
applicable law (including the Federal and state laws of the United States of America, or of any
other jurisdiction whose laws may be mandatorily applicable) with respect to the Administrative
Agent or a Lender then, in that event, notwithstanding anything to the contrary in this Agreement,
it is agreed as follows: (a) the provisions of this Section shall govern and control; (b) the
aggregate of all consideration which constitutes interest under applicable law that is contracted
for, charged or received under this Agreement, or under any of the other aforesaid

25

 

agreements or otherwise in connection with this Agreement by the Administrative Agent or such
Lender shall under no circumstances exceed the maximum amount of interest allowed by applicable law
(such maximum lawful interest rate, if any, with respect to such Lender herein called the
“Highest Lawful Rate”), and any excess shall be credited to the Borrower by the
Administrative Agent or such Lender (or, if such consideration shall have been paid in full, such
excess refunded to the Borrower); (c) all sums paid, or agreed to be paid, to the Administrative
Agent or such Lender for the use, forbearance and detention of the Indebtedness of the Borrower to
the Administrative Agent or such Lender hereunder shall, to the extent permitted by applicable law,
be amortized, prorated, allocated and spread throughout the full term of such Indebtedness until
payment in full so that the actual rate of interest is uniform throughout the full term thereof;
and (d) if at any time the interest provided pursuant to Section 4.1 together with any
other fees payable pursuant to this Agreement and the other Loan Documents and deemed interest
under applicable law, exceeds that amount which would have accrued at the Highest Lawful Rate, the
amount of interest and any such fees to accrue to the Administrative Agent or such Lender pursuant
to this Agreement shall be limited, notwithstanding anything to the contrary in this Agreement to
that amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as
applicable, shall not reduce the interest to accrue to the Administrative Agent or such Lender
pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest accrued
pursuant to this Agreement and such fees deemed to be interest equals the amount of interest which
would have accrued to the Administrative Agent or such Lender if a varying rate per annum equal to
the interest provided pursuant to Section 3.2 had at all times been in effect, plus
the amount of fees which would have been received but for the effect of this Section. For purposes
of Section 303.201 of the Texas Finance Code, as amended, to the extent, if any, applicable to the
Administrative Agent or a Lender, the Borrower agrees that the Highest Lawful Rate shall be the
“indicated (weekly) rate ceiling” as defined in said Section, provided that the Administrative
Agent or such Lender may also rely, to the extent permitted by applicable laws, on alternative
maximum rates of interest under other laws applicable to the Administrative Agent or such Lender if
greater. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan
accounts and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15))
shall not apply to this Agreement or the other Loan Documents.

Obligations under this Agreement and each other Loan Document to which it is a party and to conduct
its business substantially as currently conducted by it (except where the failure to be so

approvals will not have a Material Adverse Effect).

     SECTION 6.2 Due Authorization, Non-Contravention, etc. The execution, delivery and
performance by the Borrower of this Agreement and each other Loan Document executed or to be
executed by it, and the Borrower’s participation in any transaction contemplated herein are within

financial condition of the corporations covered thereby as at the dates thereof and the results of
their operations for the periods then ended except as disclosed in Item 6.5 (“Financial
Information”) of the Disclosure Schedule. The unaudited pro forma condensed combined balance sheet

     SECTION 6.7 Litigation, Labor Controversies, etc. As of the Effective Date and the
Initial Borrowing Date, there is no pending or, to the knowledge of the Borrower, threatened
litigation, action, proceeding, or labor controversy affecting the Borrower or any of its
Restricted Subsidiaries, or any of their respective properties, businesses, assets or revenues,
which could reasonably be expected to have a Material Adverse Effect or which purports to affect
the legality, validity or enforceability of, and the rights and remedies of the Administrative
Agent and the Lenders under, this Agreement or any other Loan Document, except as disclosed in
Item 6.7 (“Litigation”) of the Disclosure Schedule.

     SECTION 6.8 Subsidiaries. Schedule 6.8 sets forth the name, the identity or
corporate structure and the ownership interest of each direct or indirect Subsidiary as of the
Effective Date. Schedule 6.8 also sets forth the name of each Restricted Subsidiary and
Unrestricted Subsidiary as of the Effective Date. As of the Effective Date, the Borrower does not
have any Subsidiaries other than the Subsidiaries identified in Schedule 6.8.

     SECTION 6.9 Taxes. The Borrower, each of its Restricted Subsidiaries and each of its
Unrestricted Subsidiaries which is a member of the Borrower’s consolidated U.S. federal income tax
group has filed all federal tax returns and reports and all material state tax returns and

30

 

reports required by law to have been filed by it and has paid all taxes and governmental
charges thereby shown to be owing, except any such taxes or charges which are being diligently
contested in good faith by appropriate proceedings and for which adequate reserves in accordance
with GAAP shall have been set aside on its books except such returns and taxes for jurisdictions
other than the United States with respect to which the failure to file and pay such taxes would not
have a Material Adverse Effect.

     SECTION 6.10 Pension and Welfare Plans. During the twelve-consecutive-month period
prior to the date of the execution and delivery of this Agreement and prior to the date of any
Borrowing hereunder, no steps have been taken to terminate any Pension Plan, and no contribution
failure has occurred with respect to any Pension Plan sufficient to give rise to a Lien securing an
amount in excess of $1,000,000 under section 302(f) of ERISA. No condition exists or event or
transaction has occurred with respect to any Pension Plan which might result in the incurrence by
the Borrower or any member of the Controlled Group of any liability, fine or penalty which could
reasonably be expected to result in a Material Adverse Effect. Except as disclosed in Item
6.10 (“Employee Benefit Plans”) of the Disclosure Schedule, neither the Borrower nor any member
of the Controlled Group has any contingent liability with respect to any post-retirement benefit
under a Welfare Plan, other than liability for continuation coverage described in Part 6 of Title I
of ERISA.

     SECTION 6.11 Environmental Warranties and Compliance. The liabilities and costs of
the Borrower and its consolidated Restricted Subsidiaries related to compliance with applicable

ARTICLE IX

THE AGENTS

     SECTION 9.1 Actions. Each Lender hereby appoints (i) JPMCB as the Administrative
Agent under this Agreement and each other Loan Document, (ii) WACHOVIA BANK, NATIONAL ASSOCIATION
and THE ROYAL BANK OF SCOTLAND PLC, as Co-Syndication Agents under this Agreement and each other
Loan Document, and (iii) DEUTSCHE BANK SECURITIES INC. and CITIBANK, N.A., as Co-Documentation
Agents under this Agreement and each other Loan Document. Each Lender authorizes the
Administrative Agent to act on behalf of such Lender under this Agreement and each other Loan
Document and, in the absence of other written instructions from the Required Lenders received from
time to time by the Administrative Agent (with respect to which the Administrative Agent agrees
that it will comply, except as otherwise provided in this Section or as otherwise advised by
counsel), to exercise such powers hereunder and thereunder as are specifically delegated to or
required of the Administrative Agent by the terms hereof and thereof, together with such powers as
may be reasonably incidental thereto. Each Lender acknowledges that none of the Co-Syndication
Agents or the Co-Documentation Agents have any duties or obligations under this Agreement or any
other Loan Document in connection with their capacity as either a Co-Syndication Agent or a
Co-Documentation Agent, respectively. Each Lender hereby indemnifies (which indemnity shall
survive any termination of this Agreement) each of the Agents, pro rata according
to such Lender’s Percentage, WHETHER OR NOT RELATED TO ANY SINGULAR, JOINT OR CONCURRENT NEGLIGENCE
OF THE AGENTS, from and against any and all liabilities, obligations, losses, damages, claims,
costs or expenses of any kind or nature whatsoever which may at any time be imposed on, incurred
by, or asserted against, any Agent in any way relating to or arising out of this Agreement and any
other Loan Document, including reasonable attorneys’ fees, and as to which such Agent is not
reimbursed by the Borrower; provided, however, that no Lender shall be liable for
the payment of any portion of such liabilities, obligations, losses, damages, claims, costs or
expenses which are determined by a court of competent jurisdiction in a final proceeding to have
resulted solely from such Agent’s gross negligence or willful misconduct. None of the Agents shall
be required to take any action hereunder or under any other Loan Document, or to prosecute or
defend any suit in respect of this Agreement or any other Loan Document, unless it is indemnified
hereunder to its satisfaction. If any indemnity in favor of any Agent shall be or become
inadequate, in such Agent’s determination, as the case may be, such Agent may call for additional
indemnification from the Lenders and cease to do the acts indemnified against hereunder until such
additional indemnity is given. Notwithstanding any provision to the contrary contained elsewhere
in this Agreement or in any other Loan Document, none of the Agents shall have any duties or
responsibilities, except as expressly set forth herein, nor shall any of the Agents have or be
deemed to have any fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other
Loan Document or otherwise exist against any of the Agents.

     SECTION 9.2 Funding Reliance, etc. Unless the Administrative Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m., Central time, on the day
prior to a Borrowing (except with respect to a Borrowing comprised of Base Rate Loans, in which
case notice shall be given no later than 12:00 noon, Central time, on the date of the proposed
Borrowing) that such Lender will not make available the amount which would

41

 

constitute its Percentage of such Borrowing on the date specified therefor, the Administrative
Agent may assume that such Lender has made such amount available to the Administrative Agent and,
in reliance upon such assumption, make available to the Borrower a corresponding amount. If and to
the extent that such Lender shall not have made such amount available to the Administrative Agent,
such Lender and the Borrower severally agree to repay the Administrative Agent forthwith on demand
such corresponding amount together with interest thereon, for each day from the date the
Administrative Agent made such amount available to the Borrower to the date such amount is repaid
to the Administrative Agent, at the Federal Funds Rate.

     SECTION 9.3 Exculpation. None of the Agents and their respective directors, officers,
employees or agents shall be liable to any Lender for any action taken or omitted to be taken by it
under this Agreement or any other Loan Document, or in connection herewith or therewith, except for
its own willful misconduct or gross negligence, nor responsible for any recitals or warranties
herein or therein, nor for the effectiveness, enforceability, validity or due execution of this
Agreement or any other Loan Document, nor to make any inquiry respecting the performance by the
Borrower of its obligations hereunder or under any other Loan Document. Any such inquiry which may
be made by any Agent shall not obligate it to make any further inquiry or to take any action. Each
of the Agents shall be entitled to rely upon advice of counsel concerning legal matters and upon
any notice, consent, certificate, statement or writing which such Agent believes to be genuine and
to have been presented by a proper Person.

     SECTION 9.4 Successor. Any of the Agents may resign as such at any time upon at least
30 days’ prior notice to the Borrower and all Lenders. If the Administrative Agent at any time
shall resign, the Required Lenders may appoint another Lender as the successor Administrative Agent
which shall thereupon become the Administrative Agent hereunder. If no successor Administrative
Agent shall have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent’s giving notice of resignation,
then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be one of the Lenders or a commercial banking institution
organized under the laws of the U.S. (or any State thereof) or a U.S. branch or agency of a
commercial banking institution, and having a combined capital and surplus of at least $500,000,000.
Upon the acceptance of any appointment as the Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall be entitled to receive from the
retiring Administrative Agent such documents of transfer and assignment as such successor
Administrative Agent may reasonably request, and shall thereupon succeed to and become vested with
all rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations under this Agreement.
After a retiring Administrative Agent’s resignation hereunder as a Administrative Agent, the
provisions of this Article IX shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was the Administrative Agent under this Agreement, and Section
10.4 (and, with respect to the Administrative Agent, Section 10.3) shall continue to
inure to its benefit.

     SECTION 9.5 Loans by the Agents. Each of the Agents shall have the same rights and
powers with respect to the Loans made by it or any of its Affiliates and may exercise the same as
if it were not a Agent. Each of the Agents and its Affiliates may accept deposits from,

42

 

lend money to, and generally engage in any kind of business with the Borrower or any
Subsidiary or Affiliate of the Borrower as if it were not a Agent hereunder.

     SECTION 9.6 Credit Decisions. Each Lender acknowledges that it has made its own
credit decision to extend its Commitments hereunder (i) independently of each of the Agents and
each other Lender, and (ii) based on such Lender’s review of the financial information of the
Borrower, this Agreement, the other Loan Documents (the terms and provisions of which being
satisfactory to such Lender) and such other documents, information and investigations as such
Lender has deemed appropriate. Each Lender also acknowledges that it will continue to make its own
credit decisions as to exercising or not exercising from time to time any rights and privileges
available to it under this Agreement or any other Loan Document (i) independently of each of the
Agents and each other Lender, and (ii) based on such other documents, information and
investigations as it shall deem appropriate at any time.

     SECTION 9.7 Copies, etc. The Administrative Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the Administrative Agent by
the Borrower pursuant to the terms of this Agreement (unless concurrently delivered to the Lenders
by the Borrower). The Administrative Agent will distribute to each Lender each document or
instrument received for its account and copies of all other communications received by the
Administrative Agent from the Borrower for distribution to the Lenders by the Administrative Agent
in accordance with the terms of this Agreement.

ARTICLE X

MISCELLANEOUS PROVISIONS

     SECTION 10.1 Waivers, Amendments, etc. The provisions of this Agreement and of each
other Loan Document may from time to time be amended, modified or waived, if such amendment,
modification or waiver is in writing and consented to by the Borrower and the Required Lenders;
provided, however, that no such amendment, modification or waiver which would: (a)
modify any requirement hereunder that any particular action be taken by all the Lenders or by the
Required Lenders shall be effective unless consented to by each Lender; (b) modify the first
sentence of Section 4.8, Section 4.9 or this Section 10.1, change the
definition of “Required Lenders”, reduce any fees described in Article III or
extend the Maturity Date, shall be made without the consent of each Lender; (c) extend the due date
for, or reduce the amount of, any scheduled repayment or prepayment of principal of or interest on
any Loan (or reduce the principal amount of or rate of interest on any Loan) shall be made without
the consent of the Lender which made such Loan, provided that this clause (c) shall
not apply to any repayments or prepayments due as a result of Section 2.2.2(b) or
Section 2.2.2(c); or (d) affect adversely the interests, rights or obligations of any Agent
as an Agent shall be made without the consent of such Agent; provided, further,
that no such amendment, modification or waiver which would either increase any Commitment, the
Commitment Amount or the Percentage of any Lender, or modify the rights, duties or obligations of
any Agent, shall be effective without the consent of such Lender or such Agent, as applicable. No
failure or delay on the part of the Administrative Agent or any Lender in exercising any power or
right under this Agreement or any other Loan Document shall operate as a waiver thereof, nor shall
any single or partial exercise of any such power or right preclude any other or further exercise
thereof or the exercise of any other power or right. No notice to or demand on the Borrower in any
case shall entitle it

43

 

to any notice or demand in similar or other circumstances. No waiver or approval by the
Administrative Agent or any Lender under this Agreement or any other Loan Document shall, except as
may be otherwise stated in such waiver or approval, be applicable to subsequent transactions. No
waiver or approval hereunder shall require any similar or dissimilar waiver or approval thereafter
to be granted hereunder.

     (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
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

     (c) Any party hereto may change its address or telecopy number for notices and other

be deemed to have been given on the date of receipt.

     SECTION 10.3 Payment of Costs, Expenses and Taxes. The Borrower agrees to pay on
demand all reasonable out-of-pocket costs and expenses of (i) the Administrative Agent (including,
without limitation, the reasonable fees and out-of-pocket expenses of Mayer, Brown, Rowe & Maw LLP)
in connection with the preparation, negotiation, execution, delivery, syndication and
administration of this Agreement and of each other Loan Document, including schedules and exhibits,
and any amendments, waivers, consents, supplements or other modification to this Agreement or any
other Loan Document and (ii) the Administrative Agent and the Lenders in connection with the
enforcement by the Lenders or the Administrative Agent of, or the protection of rights under, this
Agreement and each other Loan Document. The Administrative Agent, the other Agents, the Arranger
and each Lender agree to the extent feasible, and to the extent a conflict of interest does not
exist in the reasonable opinion of the Administrative Agent, the other Agents, the Arranger or any
Lender, to use one law firm in each jurisdiction in connection with the foregoing, to the extent
they seek reimbursement for the expenses thereof from the Borrower. Each Lender agrees to
reimburse the Administrative Agent on demand for such Lender’s pro rata share
(based upon its respective Percentage) of any such costs or expenses not paid by the Borrower. In
addition, the Borrower agrees to pay, and to save the Administrative Agent, the other Agents, the
Arranger, and the Lenders harmless from all liability for, any stamp or other taxes which may be
payable in connection with the execution or delivery of this Agreement, the Borrowings hereunder,
or of any other instruments or documents provided for herein or delivered or to be delivered
hereunder or in connection herewith.

     SECTION 10.4 Indemnification. In consideration of the execution and delivery of this
Agreement by each Lender and the extension of the Commitments, the Borrower hereby indemnifies,
exonerates and holds each Agent, the Arranger and each Lender and each of their respective
officers, directors, employees and agents (collectively, the “Indemnified Parties”),
WHETHER OR NOT RELATED TO ANY NEGLIGENCE OF THE INDEMNIFIED PARTIES, free and harmless from and
against any and all actions, causes of action, suits, losses, costs, liabilities and damages, and
expenses incurred in connection therewith (irrespective of

45

 

whether any such Indemnified Party is a party to the action for which indemnification
hereunder is sought), whether brought by a third party or by the Borrower and regardless of whether
any Indemnified Party is a party thereto, including reasonable attorneys’ fees and disbursements
(collectively, the “Indemnified Liabilities”), incurred by the Indemnified Parties or any
of them as a result of, or arising out of, or relating to any transaction financed or to be
financed in whole or in part, directly or indirectly, with the proceeds of any Loan; the entering
into and performance of this Agreement and any other Loan Document by any of the Indemnified
Parties; any investigation, litigation or proceeding related to any acquisition or proposed
acquisition by the Borrower or any of its Restricted Subsidiaries of all or any portion of the
stock or assets of any Person, whether or not such Agent, the Arranger or such Lender is party
thereto; any investigation, litigation or proceeding related to any environmental cleanup, audit,
compliance or other matter relating to the protection of the environment or the Release by the
Borrower or any of its Restricted Subsidiaries of any Hazardous Material; or the presence on or
under, or the escape, seepage, leakage, spillage, discharge, emission, discharging or releases
from, any real property owned or operated by the Borrower or any Subsidiary thereof of any
Hazardous Material (including any losses, liabilities, damages, injuries, costs, expenses or claims
asserted or arising under any Environmental Law), regardless of whether caused by, or within the
control of, the Borrower or such Subsidiary; provided that such indemnity shall not, as to
any Indemnified Party, be available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Party
or (y) result from a claim brought by the Borrower or any Subsidiary against an Indemnified Party
for breach in bad faith of such Indemnified Party’s obligations hereunder or under any other Loan
Document, if the Borrower or such Subsidiary has obtained a final and nonappealable judgment in its
favor on such claim as determined by a court of competent jurisdiction. If and to the extent that
the foregoing undertaking may be unenforceable for any reason, the Borrower hereby agrees to make
the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities
which is permissible under applicable law.

     SECTION 10.5 Survival. The obligations of the Borrower under Sections 4.3,
4.4, 4.5, 4.6, 10.3 and 10.4, and the obligations of the
Lenders under Section 9.1, shall in each case survive any termination of this Agreement,
the payment in full of all Obligations and the termination of all Commitments.

     SECTION 10.6 Severability. Any provision of this Agreement or any other Loan Document
which is prohibited or unenforceable in any jurisdiction shall, as to such provision and such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions of this Agreement or such Loan Document or affecting the
validity or enforceability of such provision in any other jurisdiction.

     SECTION 10.7 Headings. The various headings of this Agreement and of each other Loan
Document are inserted for convenience only and shall not affect the meaning or interpretation of
this Agreement or such other Loan Document or any provisions hereof or thereof.

     SECTION 10.8 Governing Law; Entire Agreement. THIS AGREEMENT AND EACH OTHER LOAN
DOCUMENT SHALL EACH BE DEEMED TO BE A

46

 

CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT GIVING
EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS. This Agreement and the other Loan Documents constitute
the entire understanding among the parties hereto with respect to the subject matter hereof and
supersede any prior agreements, written or oral, with respect thereto.

     SECTION 10.9 Successors and Assigns. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors and assigns;
provided, however, that: (a) the Borrower may not assign or transfer its rights or
obligations hereunder without the prior written consent of the Administrative Agent and all
Lenders; and (b) the rights of sale, assignment and transfer of the Lenders are subject to
Section 10.10.

     SECTION 10.10 Sale and Transfer of Loans and Commitments; Participations in Loans and
Commitments. Each Lender may assign, or sell participations in, its Loans and Commitments to
one or more other Persons in accordance with this Section.

     SECTION 10.10.1 Assignments. Any Lender (a) with the written consent of the Borrower
(provided that the consent of the Borrower shall not be required if an Event of Default has
occurred and is continuing) and the Administrative Agent (which consent of the Borrower, if
applicable, and the Administrative Agent shall not be unreasonably delayed or withheld), may at any
time assign and delegate to one or more commercial banks or other financial institutions, and (b)
with notice to the Borrower and the Administrative Agent, but without the consent of the Borrower
or the Administrative Agent, may assign and delegate to any of its Affiliates or to any other
Lender, Lender Affiliate or Approved Fund (each Person described in either of the foregoing clauses
as being the Person to whom such assignment and delegation is to be made, being hereinafter
referred to as an “Assignee Lender”), all or any fraction of such Lender’s total Loans and
Commitments (which assignment and delegation shall be of a constant, and not a varying, percentage
of all the assigning Lender’s Loans and Commitments and which shall be of equal pro
rata shares of the Facility) in a minimum aggregate amount of $5,000,000 (or in a minimum
amount of $1,000,000 in the case of an assignment to an Approved Fund with respect to which such
Approved Fund plus the Lender or an Affiliate of such Lender who administers or manages such
Approved Fund plus other Approved Funds administered or managed by the such Lender or an Affiliate
of such Lender will then hold an amount of $5,000,000 or more); provided, however,
that any such Assignee Lender will comply, if applicable, with the provisions contained in the last
sentence of Section 4.6 and further, provided, however, that, the
Borrower and the Administrative Agent shall be entitled to continue to deal solely and directly
with such Lender in connection with the interests so assigned and delegated to an Assignee Lender
until (i) written notice of such assignment and delegation, together with payment instructions,
addresses and related information with respect to such Assignee Lender, shall have been given to
the Borrower and the Administrative Agent by such Lender and such Assignee Lender, (ii) such
Assignee Lender shall have executed and delivered to the Borrower and the Administrative Agent a
Lender Assignment Agreement, accepted by the Administrative Agent, (iii) such Assignee Lender shall
have delivered to the Administrative Agent an Administrative Questionnaire, and (iii) the
processing fees described below shall have been paid. For the purposes of this Section
10.10.1, the term “Approved Fund” has the following meaning:

47

 

““Approved Fund” means any Person (other than a natural person) that is
engaged in making, purchasing, holding or investing in bank loans and similar
extensions of credit in the ordinary course of its business and that is administered
or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
Affiliate of an entity that administers or manages a Lender.”

     From and after the date that the Administrative Agent accepts such Lender Assignment
Agreement, (x) the Assignee Lender thereunder shall be deemed automatically to have become a party
hereto and to the extent that rights and obligations hereunder have been assigned and delegated to
such Assignee Lender in connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents, and (y) the assignor Lender,
to the extent that rights and obligations hereunder have been assigned and delegated by it in
connection with such Lender Assignment Agreement, shall be released from its obligations hereunder
and under the other Loan Documents. Accrued interest on that part of the predecessor Loans and
Commitments, and accrued fees, shall be paid as provided in the Lender Assignment Agreement.
Accrued interest on that part of the predecessor Loans and Commitments shall be paid to the
assignor Lender. Accrued interest and accrued fees shall be paid at the same time or times
provided in this Agreement. Such assignor Lender or such Assignee Lender must also pay a
processing fee to the Administrative Agent upon delivery of any Lender Assignment Agreement in the
amount of $3,500. Any attempted assignment and delegation not made in accordance with this Section
shall be null and void.

     SECTION 10.10.2 Participations. Any Lender may at any time sell to one or more
commercial banks or other Persons (each of such commercial banks and other Persons being herein
called a “Participant”) participating interests in any of the Loans, Commitments or other
interests of such Lender hereunder; provided, however, that (a) no participation
contemplated in this Section 10.10 shall relieve such Lender from its Commitments or its
other obligations hereunder or under any other Loan Document, (b) such Lender shall remain solely
responsible for the performance of its Commitments and such other obligations, (c) the Borrower and
the Administrative Agent shall continue to deal solely and directly with such Lender in connection
with such Lender’s rights and obligations under this Agreement and each of the other Loan
Documents, (d) no Participant, unless such Participant is an Affiliate of such Lender, or is itself
a Lender, shall be entitled to require such Lender to take or refrain from taking any action
hereunder or under any other Loan Document, except that such Lender may agree with any Participant
that such Lender will not, without such Participant’s consent, take any actions of the type
described in clause (b) or (c) of Section 10.1, and (e) the Borrower shall
not be required to pay any amount under Section 4.6 that is greater than the amount which
it would have been required to pay had no participating interest been sold. The Borrower
acknowledges and agrees that each Participant, for purposes of Sections 4.3, 4.4,
4.5, 4.6, 4.7, 4.8, 4.9 and 10.4, shall be
considered a Lender; provided that this sentence shall not obligate the Borrower to pay more under
such Sections that it would be obligated to pay had no such participation been granted.

     SECTION 10.10.3 Pledge by Lender. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to secure obligations of
such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank,
and this Section shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a Lender
from any

48

 

of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a
party hereto.

     SECTION 10.11 Other Transactions. Nothing contained herein shall preclude the
Administrative Agent or any other Lender from engaging in any transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or any of its
Affiliates in which the Borrower or such Affiliate is not restricted hereby from engaging with any
other Person.

     SECTION 10.12 Confidentiality. Each of the Agents 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 instructed to keep such
Information confidential), (b) to the extent requested by any regulatory authority or
self-regulatory body, (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, (e) in connection with
the exercise of any remedies hereunder 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, 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 hedging agreement, (g) with the consent of Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of this Section by
any Person or (ii) becomes available to any Agent or any Lender on a nonconfidential basis from a
source other than Borrower or any of its Affiliates. For the purposes of this Section,
“Information” means all information received from Borrower or its Affiliate relating to
Borrower and its Subsidiaries or their business, other than any such information that is available
to any Agent or any Lender on a nonconfidential basis prior to disclosure by Borrower or any of its
Affiliates. Any Person required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its 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.

     SECTION 10.13 Forum Selection and Consent to Jurisdiction. ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT,
OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF

IN THE COURTS OF THE STATE OF TEXAS OR NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE

WITHOUT THE STATE OF TEXAS. THE BORROWER, THE ADMINISTRATIVE AGENT, AND EACH LENDER HEREBY
EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT
MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH
COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM. TO THE EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION
OF ANY COURT OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO
JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE
BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS.

     SECTION 10.14 Waiver of Jury Trial. THE ADMINISTRATIVE AGENT, THE LENDERS AND THE
BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL

THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR
THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND
THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT AND THE LENDERS ENTERING

itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the
requirements of the USA Patriot Act, it is required to obtain, verify and record information that
identifies the Borrower, which information includes the name and address of the Borrower and other
information that will allow such Lender or the Administrative Agent, as applicable, to identify the

EXHIBIT 5.1.4

OPINION OF COUNSEL TO THE BORROWER

April 4, 2005

The Lenders and the Agents Party to the Credit Agreement

c/o JPMorgan Chase Bank, N.A.,

     as Administrative Agent for the Lenders

1111 Fannin Street, 10th Floor

Houston, Texas 77002

Ladies and Gentlemen:

     We have acted as counsel to Noble Energy, Inc., a Delaware corporation (“Borrower”), in
connection with the $1,300,000,000 Credit Agreement dated as of April 4, 2005 (the “Agreement”)
among Borrower, JPMorgan Chase Bank, N.A., individually and as administrative agent for the Lenders
(“Agent”), certain Co-Documentation Agents, certain Co-Syndication Agents, and Lenders named
therein. This opinion letter is delivered to you pursuant to Section 5.1.3 of the
Agreement. Capitalized terms used but not otherwise defined herein shall have the meanings given
to them in the Agreement.

     In our capacity as counsel for Borrower, we have examined executed originals or telecopies of
executed originals of the Agreement and the other Loan Documents that have been executed and
delivered to you by Borrower today in connection with the Agreement. We have also examined and
relied upon originals or copies, certified or otherwise authenticated to our satisfaction, of such
corporate records of Borrower, certificates of officers of Borrower, certificates and letters of
public officials, and other instruments and documents as we have deemed necessary to require as a
basis for the opinions hereinafter expressed. In such examination, we have assumed the genuineness
and authenticity of all documents submitted to us as originals (other than the Loan Documents), the
conformity with genuine and authentic originals of all documents submitted to us as copies, and the
genuineness of all signatures (other than the signatures on behalf of Borrower on the Loan
Documents).

     Where facts material to the opinions hereinafter expressed were not independently established
by us, we have relied upon the representations and warranties made to you by Borrower in the Loan
Documents and upon oral and written statements of and information furnished by officers of Borrower
and its Subsidiaries, where we deemed such reliance appropriate under the circumstances. We have
necessarily assumed the accuracy and completeness of such representations, warranties, statements
and other information.

     Based on the foregoing and on the assumptions hereinafter set forth, and subject to the
exceptions, limitations and qualifications hereinafter expressed, it is our opinion that:

     1. Borrower is a duly incorporated and validly existing corporation in good standing
under the laws of the State of Delaware and has the corporate power and

 

 

authority to own its property and assets and to transact the business in which it is
engaged. Borrower is duly qualified and is authorized to do business and is in good
standing as a foreign corporation in the State of Texas. Borrower has the corporate power
to execute, deliver and carry out the terms and provisions of each of the Loan Documents to
which it is a party and has taken all necessary corporate action to authorize the execution,
delivery and performance by it of each of such Loan Documents.

     2. The execution, delivery and performance by Borrower of the Agreement and each other
Loan Document executed by it are within its corporate powers, have been duly authorized by
all necessary corporate action, and do not (i) violate the certificate of incorporation or
by-laws of Borrower, (ii) violate, constitute a breach of or result in the imposition or
creation of (or the obligation to impose or create) a Lien pursuant to, any of the terms or
provisions of any indenture, loan agreement or other agreement to which Borrower is a party
or by which Borrower or its property is bound that is filed as (or incorporated by reference
as) an exhibit to Borrower’s Annual Report on Form 10-K for the fiscal year ended December
31, 2004, (iii) violate any applicable statute, rule or regulation of any governmental body
of the United States of America or the State of Texas, or (iv) to the knowledge of the
undersigned, any court decree or order binding upon Borrower.

     3. No authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body pursuant to any law or any rule or order of
general application is required for the due execution, delivery or performance by Borrower
of any Loan Document to which it is a party.

     4. Neither Borrower nor any of its Subsidiaries is an “investment company” within the
meaning of the Investment Company Act of 1940, as amended, or 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,” within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

     5. Each of the Loan Documents to which Borrower is a party has been duly executed and
delivered by Borrower. The Loan Documents constitute the legal, valid and binding
obligations of Borrower enforceable in accordance with their respective terms, except as
enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization or
other similar laws affecting creditors’ rights generally and equitable principles of general
applicability.

     6. To the knowledge of the undersigned, there is no pending or threatened litigation,
action, proceeding, or labor controversy affecting Borrower or any of its Subsidiaries,
properties, businesses, assets or revenues, which purports to affect the legality, validity
or enforceability of, or the rights and remedies of Agent and the Lenders under, the
Agreement or any other Loan Document.

     The opinions expressed above are based in part upon the assumptions, and are subject to the
exceptions, limitations and qualifications, set forth below:

 

 

     (a) Whenever any opinion expressed herein with respect to any matter is qualified by
the phrase “to the knowledge of the undersigned,” such phrase (A) indicates that (i) no
information has come to the attention of any attorney of this firm who has devoted
substantive attention to the transactions contemplated in the Agreement that has given any
such person actual knowledge concerning such matter different from that expressed in such
opinion; (ii) except as otherwise stated herein, we have not undertaken any independent
investigation with respect to such matter but have relied on representations made by
Borrower in the Loan Documents and on information otherwise provided to us by it; and (iii)
no inference that any such person has actual knowledge concerning such matters should be
drawn from the fact of our representation of Borrower and its Subsidiaries or our expression
of such opinion; and (B) does not encompass the actual knowledge of any attorney of this
firm who obtained such knowledge in his capacity as a director of Borrower.

     (b) Except as expressly set forth herein, we have made no independent investigation as
to the accuracy or completeness of any representation, warranty, data or other information,
written or oral, made or furnished in or in connection with the Loan Documents, or
otherwise.

     (c) We do not purport to be experts as to the laws of any jurisdiction other than the
State of Texas and the United States of America, and we express no opinion herein with
respect to the laws of any such other jurisdiction, except insofar as the matters covered by
the foregoing opinions may involve or be governed by or construed under the General
Corporation Law of the State of Delaware. Our opinion regarding the General Corporation Law
of the State of Delaware is confined to our reading thereof without application of judicial
or administration interpretations thereof.

     (d) In rendering certain of the opinions expressed above, we have assumed that each of
the Agents and Lenders (i) are duly authorized to execute and deliver (or accept), and have
duly executed and delivered (or accepted), the Loan Documents required to be executed and
delivered (or accepted) by it and (ii) each Lender will fund the Loans to the extent
required to be funded by it under the Agreement.

     (e) We express no opinion concerning (i) any right of any Agent or any Lender or any
other person to be indemnified against (or released from the consequences of) its own
negligence or willful misconduct; (ii) the enforceability of any obligations of any party
other than Borrower; (iii) the effectiveness or enforceability of provisions restricting
access to courts or to legal or equitable remedies or purporting to affect jurisdiction or
venue; or (iv) the effectiveness or enforceability of any waiver of the right to trial by
jury or any rights or benefits that cannot be waived under applicable law.

     (f) For purposes of this opinion, we have assumed that the Borrower is, and in
connection with each incurrence of Indebtedness under the Agreement will be, in compliance
with the covenants contained in Sections 7.2.3(a) and (b) of (i) the
Agreement, (ii) the $400,000,000 Credit Agreement dated as of November 30, 2001, as amended,
among Borrower (formerly known as Noble Affiliates, Inc.), JPMorgan Chase Bank as
Administrative Agent, and the Co-Documentation Agents, Syndication Agent

 

 

and Lenders referred to therein, and (iii) the $400,000,000 Credit Agreement dated as
of October 28, 2004, as amended, among Borrower, JPMorgan Chase Bank as Administrative
Agent, and the Co-Documentation Agents, Syndication Agent and Lenders referred to therein;
and contained in Sections 7.2.3(a) and (b) of: (i) the Term Loan Agreement dated as
of January 30, 2004, among Noble Energy Mediterranean Ltd., Sumitomo Mitsui Banking
Corporation as Initial Lender and as Agent for the Lenders, (ii) the Term Loan Agreement
dated as of February 2, 2004, among Noble Energy Mediterranean Ltd., Bank One, NA as Agent
for the Lenders and certain commercial lending institutions, and (iii) the Term Loan
Agreement dated as of February 4, 2004, among Noble Energy Mediterranean Ltd., the Royal
Bank of Scotland Finance (Ireland) as Agent for the Lenders and as the initial Lender, each
of which Sections 7.2.3(a) and (b) are worded identically to Sections
7.2.3(a) and (b) of the Agreement.

     This opinion letter is to be limited in its use to reliance by you and your counsel in
consummating the Agreement. No other person or entity (other than the Lenders and the Assignee
Lenders or their counsel) may rely or claim reliance on any opinion expressed herein except with
our express written consent. We assume no obligation to supplement this opinion if, after the date
hereof, any applicable law changes or we become aware of any facts that might change the opinions
set forth herein.

Respectfully submitted,
