          CREDIT AGREEMENT, dated as December 22, 2005, among NOBLE CORPORATION, a Cayman Islands exempted company limited by shares (“Parent”), NOBLE HOLDING (U.S.) CORPORATION, a Delaware corporation (“NHC” and, together with Parent, the “Parent Guarantors”), NOBLE DRILLING CORPORATION (the “Borrower”), a Delaware corporation, and ▇▇▇▇▇▇▇ ▇▇▇▇▇ CREDIT PARTNERS L.P. (“GSCP”), as initial Lender and Administrative Agent (in such capacity the “Administrative Agent”). Unless otherwise defined herein, all capitalized terms used herein and defined in Section 10 are used herein as so defined.

W I T N E S S E T H:

          WHEREAS, the parties hereto desire to enter into this Agreement to make available to the Borrower a loan facility in an aggregate principal amount as provided for herein;

          NOW, THEREFORE, it is agreed:

          SECTION 1. Amount and Terms of Credit.

          1.01 Commitment. Subject to and upon the terms and conditions herein set forth, each Lender severally agrees to make a loan or loans (each a “Loan” and, collectively, the “Loans”) under the Facility to the Borrower on the Closing Date in an amount equal to such Lender’s Commitment.

          1.02 Reserved

          1.03 Notice of Borrowing. The Borrower shall give the Administrative Agent at its Notice Office, prior to 12:00 Noon (New York time), at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing), or such shorter time as the Lenders may agree, of a Borrowing of Eurodollar Loans and at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) of a Borrowing of Base Rate Loans to be made hereunder. Such notice (the “Notice of Borrowing”) shall be in the form of Exhibit A and shall be irrevocable and shall specify (i) the aggregate principal amount of the Loans to be made on the Closing Date, (ii) the date of Borrowing (which shall be a Business Day) and (iii) whether the Borrowing shall consist of Base Rate Loans or (to the extent permitted) Eurodollar Loans and, if Eurodollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent shall promptly give each Lender written notice (or telephonic notice promptly confirmed in writing) of the proposed Borrowing, of such Lender’s proportionate share thereof and of the other matters covered by the Notice of Borrowing.

          1.04 Disbursement of Funds. (a) No later than 12:00 Noon (New York time) on the date specified in the Notice of Borrowing, each Lender will make available its pro rata share of the Borrowing requested to be made on such date in the manner provided below. All such amounts shall be made available to the Administrative Agent in Dollars and immediately available funds at the Payment Office and the Administrative Agent promptly will make available to the Borrower by depositing to its account at the Payment Office the aggregate of the amounts so made available in Dollars and immediately available funds. Unless the Administrative Agent shall have been notified by any Lender prior to the date of Borrowing that

such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing to be made on the Closing Date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available same to the Borrower, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall (within two Business Days of receiving such demand) pay such corresponding amount to the Administrative Agent. The Administrative Agent shall also be entitled to recover on demand from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (x) if paid by such Lender, the overnight Federal Funds Effective Rate or (y) if paid by the Borrower, the then applicable rate of interest, calculated in accordance with Section 1.08, for the respective Loans.

          (b) Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any default by such Lender hereunder.

          1.05 Notes. (a) The Borrower’s obligation to pay the principal of, and interest on, the Loan made to it by each Lender shall be evidenced in the Register maintained by the Administrative Agent pursuant to Section 13.16, and shall, if requested by such Lender, also be evidenced by a promissory note substantially in the form of Exhibit B with blanks appropriately completed in conformity herewith (each a “Note” and, collectively, the “Notes”).

          (b) The Note issued to each Lender shall (i) be executed by the Borrower, (ii) be payable to the order of such Lender and be dated the Closing Date or, if issued after the Closing Date, be dated the date of issuance thereof, (iii) be in a stated principal amount equal to the Loans held by such Lender on such date and be payable in the outstanding principal amount of the Loans evidenced thereby, (iv) mature on the Maturity Date, (v) bear interest as provided in the appropriate clause of Section 1.08 in respect of the outstanding Base Rate Loans and Eurodollar Loans, as the case may be, evidenced thereby, (vi) be subject to mandatory repayment as provided in Section 4.02 and (vii) be entitled to the benefits of this Agreement and the other Credit Documents.

          (c) Each Lender will note on its internal records the amount of each Loan made by it and each payment in respect thereof and will, prior to any transfer of any of its Notes, endorse on the reverse side thereof the outstanding principal amount of Loans evidenced thereby. Failure to make any such notation or any error in such notation shall not affect the Borrower’s obligations in respect of such Loans.

          1.06 Conversions. The Borrower shall have the option to convert on any Business Day all or a portion at least equal to the applicable Minimum Borrowing Amount of the

outstanding principal amount of Loans into a Borrowing or Borrowings of another Type of Loan, provided that (i) except as otherwise provided in Section 1.10(b), Eurodollar Loans may be converted into Base Rate Loans only on the last day of an Interest Period applicable thereto and no partial conversion of a Borrowing of Eurodollar Loans shall reduce the outstanding principal amount of the Eurodollar Loans made pursuant to such Borrowing to less than the Minimum Borrowing Amount applicable thereto and (ii) no Base Rate Loans may be converted into Eurodollar Loans at any time when a Specified Default is in existence on the date of the conversion if the Administrative Agent or the Required Lenders have determined that such a conversion would be disadvantageous to the Lenders. Each such conversion shall be effected by the Borrower giving the Administrative Agent at its Notice Office, prior to 12:00 Noon (New York time), at least three Business Days’ (or one Business Day’s, in the case of a conversion into Base Rate Loans) prior written notice (or telephonic notice promptly confirmed in writing) (each a “Notice of Conversion”) specifying the Loans to be so converted, the Type of Loans to be converted into and, if to be converted into a Borrowing of Eurodollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent shall give prompt notice of any such proposed conversion to each Lender with Loans affected thereby.

          1.07 Pro Rata Borrowings. All Loans under this Agreement shall be made by the Lenders pro rata on the basis of their Commitments. It is understood that no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder.

          1.08 Interest. (a) The unpaid principal amount of each Base Rate Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum which shall at all times be the Base Rate in effect from time to time.

          (b) The unpaid principal amount of each Eurodollar Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum which shall at all times be the Eurodollar Rate plus the Applicable Eurodollar Margin.

          (c) All overdue principal and, to the extent permitted by law, overdue interest in respect of each Loan and any other overdue amount payable hereunder shall bear interest at a rate per annum equal to 2% per annum in excess of the rate otherwise applicable to such Loans from time to time (or, if such amounts do not relate to a specific Loan, 2% in excess of the Base Rate as in effect from time to time), with such interest payable on demand.

          (d) Interest shall accrue from and including the date of any Borrowing to but excluding the date of any repayment thereof and shall be payable (i) in respect of each Base Rate Loan, quarterly in arrears on the last Business Day of each March, June, September and December, (ii) in respect of each Eurodollar Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in excess of three months, on each date occurring at three month intervals after the first day of such Interest Period, (iii) in respect of each Eurodollar Loan, on any prepayment or conversion (on the amount prepaid or converted) and (iv) in respect of each Loan, at maturity (whether by acceleration or otherwise) and, after such maturity, on demand.

          (e) All computations of interest hereunder shall be made in accordance with Section 13.07(b).

          (f) The Administrative Agent, upon determining the interest rate for any Borrowing of Eurodollar Loans for any Interest Period, shall promptly notify the Borrower and the Lenders thereof.

          1.09 Interest Periods. (a) At the time the Borrower gives the Notice of Borrowing or a Notice of Conversion in respect of the making of, or conversion into, a Borrowing of Eurodollar Loans (in the case of the initial Interest Period applicable thereto) or on the third Business Day prior to the expiration of an Interest Period applicable to an outstanding Borrowing of Eurodollar Loans (in the case of any subsequent Interest Period), the Borrower shall have the right to elect, by giving the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) thereof, the interest period (each, an “Interest Period”) applicable to such Borrowing of Eurodollar Loans, which Interest Period shall be a one month period. Notwithstanding anything to the contrary contained above:

     (i) the initial Interest Period for any Borrowing of Eurodollar Loans shall commence on the date of such Borrowing (including the date of any conversion from a Borrowing of Base Rate Loans) and each Interest Period occurring thereafter in respect of such Borrowing shall commence on the day on which the immediately preceding Interest Period expires;

     (ii) if any Interest Period begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of such calendar month;

     (iii) if any Interest Period would otherwise expire on a day which is not a Business Day, such Interest Period shall expire on the next succeeding Business Day, provided that if any Interest Period would otherwise expire on a day which is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the immediately preceding Business Day;

     (iv) no Interest Period shall extend beyond the Maturity Date; and

     (v) no Interest Period may be elected at any time when a Specified Default is then in existence if the Administrative Agent or the Required Lenders have determined that such an election at such time would be disadvantageous to the Lenders.

          (b) If upon the expiration of any Interest Period, the Borrower has failed to (or may not) elect a new Interest Period to be applicable to the respective Borrowing of Eurodollar Loans as provided above, the Borrower shall be deemed to have elected to convert such Borrowing into a Borrowing of Base Rate Loans effective as of the expiration date of such current Interest Period.

          1.10 Increased Costs, Illegality, etc. (a) In the event that (x) in the case of clause (i) below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender

shall have determined (which determination shall, absent demonstrable error, be final and conclusive and binding upon all parties hereto):

     (i) on any date for determining the Eurodollar Rate for any Interest Period that, by reason of any changes arising after the date of this Agreement affecting the interbank Eurodollar market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate; or

     (ii) at any time, that such Lender shall incur actual increased costs or reductions in the amounts received or receivable hereunder with respect to any Eurodollar Loans because of (x) any change since the date of this Agreement in any applicable law, governmental rule, regulation, guideline or order (whether or not having the force of law) or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or order (such as, for example, but not limited to: (A) without duplication of any amounts payable under Section 4.04(a), a change in the basis of taxation or payment to any Lender of the principal of or interest on such Eurodollar Loans or any other amounts payable hereunder (except for changes with respect to any tax imposed on, or determined by reference to, the net income or net profits of such Lender pursuant to the laws of the United States, the jurisdiction in which such Lender is organized or in which such Lender’s principal office or applicable lending office is located or any subdivision thereof or therein), or (B) a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of the Eurodollar Rate) and/or (y) other circumstances occurring after the date of this Agreement and affecting the interbank Eurodollar market; or

     (iii) at any time since the date of this Agreement, that the making or continuance of any Eurodollar Loan has become unlawful by compliance by such Lender in good faith with any law, governmental rule, regulation, guideline or order (or would conflict with any such governmental rule, regulation, guideline, request or order not having the force of law but with which such Lender customarily complies even though the failure to comply therewith would not be unlawful), or has become impracticable as a result of a contingency occurring after the date of this Agreement which materially and adversely affects the interbank Eurodollar market;

then, and in any such event, such Lender (or the Administrative Agent in the case of clause (i) above) shall (x) on such date and (y) within ten Business Days of the date on which such event no longer exists, give notice (by telephone confirmed in writing) to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and the Notice of Borrowing or any Notice of Conversion given by the Borrower with respect to Eurodollar Loans which have not yet been incurred shall be deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the Borrower shall, subject to Section 1.12(b) (to the extent applicable), pay to such Lender, upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of

calculating, interest or otherwise as such Lender in its sole discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder (a written notice as to the additional amounts owed to such Lender, showing the basis for the calculation thereof, submitted to the Borrower by such Lender shall, absent demonstrable error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 1.10(b) as promptly as possible and, in any event, within the time period required by law.

          (b) At any time that any Eurodollar Loan is affected by the circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may (and in the case of a Eurodollar Loan affected pursuant to Section 1.10(a)(iii), the Borrower shall) either (i) if the affected Eurodollar Loan is then being made pursuant to a Borrowing, cancel said Borrowing by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to Section 1.10(a)(ii) or (iii), or (ii) if the affected Eurodollar Loan is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such Eurodollar Loan into a Base Rate Loan, provided that if more than one Lender is affected at any time, then all affected Lenders must be treated the same pursuant to this Section 1.10(b).

          (c) If any Lender shall have determined that after the date of this Agreement, the adoption or effectiveness of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender with any request or directive regarding capital adequacy (whether or not having the force of law but with which such Lender customarily complies even though the failure to comply therewith would not be unlawful) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s policies with respect to capital adequacy), then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall, subject to Section 1.12(b) (to the extent applicable), pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 1.10(c), will give prompt written notice thereof to the Borrower, which notice shall set forth the basis of the calculation of such additional amounts, although the failure to give any such notice shall not release or diminish any of the Borrower’s obligations to pay additional amounts pursuant to this Section 1.10(c) upon the subsequent receipt of such notice.

          1.11 Compensation. The Borrower shall compensate each Lender, upon its written request (which request shall set forth the basis for requesting such compensation), for all reasonable losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its Eurodollar Loans but excluding in any event the loss of anticipated profits) which such Lender may sustain: (i) if for any reason (other than a default by such Lender or the Administrative Agent) a Borrowing of Eurodollar Loans does not occur on a

date specified therefor in the Notice of Borrowing or any Notice of Conversion (whether or not withdrawn by the Borrower or deemed withdrawn pursuant to Section 1.10(a)); (ii) if any prepayment, repayment or conversion of any of its Eurodollar Loans occurs on a date which is not the last day of an Interest Period applicable thereto; (iii) if any prepayment of any of its Eurodollar Loans is not made on any date specified in a notice of prepayment given by the Borrower; or (iv) as a consequence of (x) any other default by the Borrower to repay its Eurodollar Loans when required by the terms of this Agreement or (y) an election made pursuant to Section 1.10(b) or 1.14. A Lender’s basis for requesting compensation pursuant to this Section 1.11 and a Lender’s calculation of the amount thereof, shall, absent demonstrable error, be final and conclusive and binding on all parties hereto. Notwithstanding the foregoing provisions of this Section 1.11, GSCP agrees that it will not make any claim under this Section 1.11 in its capacity as Lender for such losses, expenses and liabilities described in this Section 1.11.

          1.12 Change of Lending Office; Limitation on Indemnities. (a) Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 1.10(a)(ii) or (iii), 1.10(c) or 4.04 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loan, or Commitments affected by such event, provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 1.12 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in Section 1.10 or 4.04.

          (b) Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 1.10 or 4.04 is given by any Lender more than 90 days after such Lender obtained, or reasonably should have obtained, knowledge of the occurrence of the event giving rise to the additional costs of the type described in such Section, such Lender shall not be entitled to compensation under Section 1.10 or 4.04 for any amounts incurred or accruing prior to the date which is 90 days prior to the giving of such notice to the Borrower.

          1.13 Replacement of Lenders. (x) Upon the occurrence of any event giving rise to the operation of Section 1.10(a)(ii) or (iii), Section 1.10(c) or Section 4.04 with respect to any Lender which results in such Lender charging to the Borrower increased costs in excess of those being charged by the other Lenders or becoming incapable of making Eurodollar Loans, (y) if a Lender becomes a Defaulting Lender and/or (z) as provided in Section 13.12(b), in the case of a refusal by a Lender to consent to a proposed change, waiver, discharge or termination with respect to this Agreement which has been approved by the Required Lenders, the Borrower shall have the right, if no Default or Event of Default then exists, to replace such Lender (the “Replaced Lender”) with one or more other Eligible Transferee or Transferees reasonably acceptable to the Administrative Agent, none of which Transferees shall constitute a Defaulting Lender at the time of such replacement (collectively, the “Replacement Lender”), provided that (i) at the time of any replacement pursuant to this Section 1.13, the Replacement Lender shall enter into one or more Assignment and Assumption Agreements pursuant to Section 13.04(b) (and with all fees payable pursuant to said Section 13.04(b) to be paid by the Replacement Lender) pursuant to which the Replacement Lender shall acquire all of the Commitments and

outstanding Loans of the Replaced Lender and, in connection therewith, shall pay to (x) the Replaced Lender in respect thereof an amount equal to the principal of, and all accrued interest on, all outstanding Loans of the Replaced Lender, and (ii) all obligations of the Borrower owing to the Replaced Lender (other than those specifically described in clause (i) above in respect of which the assignment purchase price has been, or is concurrently being, paid) shall be paid in full to such Replaced Lender concurrently with such replacement. Upon the execution of the respective Assignment and Assumption Agreements, the payment of amounts referred to in clauses (i) and (ii) above and, if so requested by the Replacement Lender, delivery to the Replacement Lender of a Note executed by the Borrower, the Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder, except with respect to indemnification provisions applicable to the Replaced Lender under this Agreement, which shall survive as to such Replaced Lender.

The Borrower shall have the right to prepay Loans in whole or in part, without premium or penalty, from time to time on the following terms and conditions: (i) the Borrower shall give the Administrative Agent at the Payment Office written notice (or telephonic notice promptly confirmed in writing) of its intent to prepay the Loans, the amount of such prepayment and (in the case of Eurodollar Loans) the specific Borrowing or Borrowings pursuant to which made, which notice shall be given by the Borrower at least one Business Day prior to the date of such prepayment with respect to Base Rate Loans and three Business Days prior to the date of such prepayment with respect to Eurodollar Loans, which notice shall promptly be transmitted by the Administrative Agent to each of the Lenders; (ii) each partial prepayment of any Borrowing shall be in an aggregate principal amount of at least $500,000 and, if greater in an integral multiple of $100,000, provided that no partial prepayment of Eurodollar Loans made pursuant to a Borrowing shall reduce the aggregate principal amount of the Loans outstanding pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount applicable thereto; (iii) Eurodollar Loans may only be prepaid pursuant to this Section 4.01 on the last day of the Interest Period applicable thereto, unless prior prepayment is accompanied by all breakage costs owing pursuant to Section 1.11 in connection therewith; and (iv) each prepayment in respect of any Loans made pursuant to a Borrowing shall be distributed pro rata among the Lenders which made such Loans, provided that, at the Borrower’s election in connection with any prepayment of Loans pursuant to this Section 4.01, such prepayment shall not be applied to any Loans of a Defaulting Lender.

          4.02 Mandatory Repayments.

          (A) Requirements:

          (a) If on any date any Loan Party shall issue any Indebtedness which is permitted by Section 9.03(b) or (g) (other than Indebtedness under the Amended and Restated Credit

Agreement), the Borrower shall repay within one Business Day of such date the principal of Loans in an aggregate amount equal to the net cash proceeds from such issuance of Indebtedness.

          (b) Notwithstanding anything to the contrary contained elsewhere in this Agreement, all then outstanding Loans shall be repaid in full on the Maturity Date.

          (c) On the date on which any Change of Control occurs, unless otherwise agreed by the Required Lenders, the outstanding principal amount of all Loans, if any, shall become due and payable in full.

          (B) Application:

          With respect to each prepayment of Loans required by Section 4.02, the Borrower may designate the Types of Loans which are to be prepaid and the specific Borrowing or Borrowings pursuant to which made, provided that (i) repayments of Eurodollar Loans may only be made pursuant to this Section 4.02 on the last day of an Interest Period applicable thereto unless no Base Rate Loans remain outstanding; (ii) if any prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Loans made pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount for such Borrowing, such Borrowing shall be converted into Base Rate Loans at the end of the then current Interest Period applicable thereto; and (iii) each prepayment of any Loans made pursuant to a Borrowing shall be applied pro rata among the Lenders which made such Loans. In the absence of a designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its sole discretion with a view, but no obligation, to minimize breakage costs owing under Section 1.11. Notwithstanding the foregoing provisions of this Section 4.02(B), if at any time the mandatory prepayment of Loans pursuant to Section 4.02(A) above would result, after giving effect to the procedures set forth above, in the Borrower incurring breakage costs under Section 1.11 as a result of Eurodollar Loans being prepaid other than on the last day of an Interest Period applicable thereto (the “Affected Eurodollar Loans”), then the Borrower may in its sole discretion initially deposit a portion (up to 100%) of the amounts that otherwise would have been paid in respect of the Affected Eurodollar Loans with the Administrative Agent (which deposit must be equal in amount to the amount of the Affected Eurodollar Loans not immediately prepaid) to be held as security for the obligations of the Borrower hereunder pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to the Administrative Agent and shall provide for investments in Cash Equivalents satisfactory to the Administrative Agent and the Borrower, with such cash collateral to be directly applied upon the first occurrence (or occurrences) thereafter of the last day of an Interest Period applicable to the relevant Loans that are Eurodollar Loans (or such earlier date or dates as shall be requested by the Borrower), to repay an aggregate principal amount of such Loans equal to the Affected Eurodollar Loans not initially prepaid pursuant to this sentence. Notwithstanding anything to the contrary contained in the immediately preceding sentence, all amounts deposited as cash collateral pursuant to the immediately preceding sentence shall be held for the sole benefit of the Lenders whose Loans would otherwise have been immediately prepaid with the amounts deposited and upon the taking of any action by the Administrative Agent or the Lenders pursuant to the remedial provisions of Section 10, any amounts held as cash collateral pursuant to this Section 4.02(B) shall, subject to the requirements of applicable law, be immediately applied to such Loans.

          4.03 Method and Place of Payment. Except as otherwise specifically provided herein, all payments under this Agreement shall be made to the Administrative Agent for the ratable (based on its pro rata share) account of the Lenders entitled thereto, not later than 1:00 P.M. (New York time) on the date when due and shall be made in immediately available funds and in lawful money of the United States at the Payment Office, it being understood that written notice by the Borrower to the Administrative Agent to make a payment from the funds in the Borrower’s account at the Payment Office shall constitute the making of such payment to the extent of such funds held in such account. Any payments under this Agreement which are made later than 1:00 P.M. (New York time) shall be deemed to have been made on the next succeeding Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension.

          4.04 Net Payments. (a) All payments made by any Credit Party hereunder or under any Note will be made without setoff, counterclaim or other defense. Except as provided in Section 4.04(b), all such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, except as provided in the second succeeding sentence, any tax imposed on or measured by the net income or net profits of a Lender pursuant to the laws of the jurisdiction in which it is organized or managed and controlled or the jurisdiction in which the principal office or applicable lending office of such Lender is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower and each Parent Guarantor, jointly and severally, agree to pay the full amount of such Taxes, and such additional amounts, if any, as may be necessary so that every payment of all amounts due under this Agreement or under any Note, after withholding or deduction for or on account of any Taxes, will not be less than the amount provided for herein or in such Note. If any amounts are payable in respect of Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each Lender, upon the written request of such Lender, for taxes imposed on or measured by the net income or net profits of such Lender pursuant to the laws of the jurisdiction in which the principal office or applicable lending office of such Lender is located or under the laws of any political subdivision or taxing authority of any such jurisdiction in which the principal office or applicable lending office of such Lender is located and for any withholding of taxes as such Lender shall determine are payable by, or withheld from, such Lender in respect of such amounts so paid to or on behalf of such Lender pursuant to the preceding sentence and in respect of any amounts paid to or on behalf of such Lender pursuant to this sentence. The Borrower will furnish to the Administrative Agent within 45 days after the date the payment of any Tax is due pursuant to applicable law certified copies of tax receipts evidencing such payment by the Borrower. The Borrower and each Parent Guarantor, jointly and severally, agree to indemnify and hold harmless each Lender, and reimburse such Lender upon its written request, for the amount of any Taxes so levied or imposed and paid by such Lender.

          (b) Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower and the Administrative Agent on or prior to the date of this Agreement, or in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 1.13 or 13.04 (unless the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (i) two accurate and complete original signed copies of Internal Revenue Service Form W-8ECI or W-8BEN (or successor forms) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note, or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service Form W-8ECI or W-8BEN pursuant to clause (i) above, (x) a certificate substantially in the form of Exhibit E (any such certificate, a “Section 4.04(b)(ii) Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN (or successor form) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Note. In addition, each Lender agrees that from time to time after the date of this Agreement, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to the Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form W-8ECI or W-8BEN (with respect to the benefits of any income tax treaty), or Form W-8BEN (with respect to the portfolio interest exemption) and a Section 4.04(b)(ii) Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement and any Note, or it shall immediately notify the Borrower and the Administrative Agent of its inability to deliver any such Form or Certificate. Notwithstanding anything to the contrary contained in Section 4.04(a), but subject to Section 13.04(b) and the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent that such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 4.04(a) hereof to gross-up payments to be made to a Lender in respect of income or similar taxes imposed by the United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the Borrower pursuant to this Section 4.04(b) or (II) in the case of a payment, other than interest, to a Lender described in clause (ii) above, to the extent that such Forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this Section 4.04 and except as set forth in Section 13.04(b), the Borrower agrees to pay additional amounts and to indemnify each Lender in the manner set forth in Section 4.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts deducted or withheld by it as described in the immediately preceding sentence as a result of any changes after the date of this Agreement in any applicable law, treaty,

governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of income or similar Taxes, provided such Lender shall provide to the Borrower and the Administrative Agent any reasonably available applicable IRS tax form (reasonably similar in its simplicity and lack of detail to IRS Form W-8ECI or W-8BEN) necessary or appropriate for the exemption or reduction in the rate of such U.S. federal withholding tax.

          (c) The provisions of this Section 4.04 shall be subject to Section 1.12(b) (to the extent applicable).

          SECTION 12. The Administrative Agent.

          12.01 Appointment. The Lenders hereby designate GSCP as Administrative Agent to act as specified herein and in the other Credit Documents. Each Lender hereby irrevocably authorizes, and each holder of any Note by the acceptance of such Note shall be deemed irrevocably to authorize, the Administrative Agent to take such action on its behalf under the provisions of this Agreement, the other Credit Documents and any other instruments and agreements referred to herein or therein and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Administrative Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder by or through its respective officers, directors, agents, employees or Affiliates (including by appointing one or more of its banking Affiliates to act as Administrative Agent hereunder).

          12.02 Nature of Duties. The Administrative Agent shall not have any duties or responsibilities except those expressly set forth in this Agreement and the other Credit Documents. Neither the Administrative Agent nor any of its respective officers, directors, agents, employees or Affiliates shall be liable for any action taken or omitted by it or them hereunder or under any other Credit Document or in connection herewith or therewith, unless caused by its or their gross negligence or willful misconduct. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Lender or the holder of any Note; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

          12.03 Lack of Reliance on the Administrative Agent. Independently and without reliance upon the Administrative Agent, each Lender and the holder of each Note, to the extent it deems appropriate, has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of Parent and its Subsidiaries in connection with the making and the continuance of the Loans and the taking or not taking of any action in connection herewith and (ii) its own appraisal of the creditworthiness of Parent and its Subsidiaries and, except as expressly provided in this Agreement, the Administrative Agent shall not have any

duty or responsibility, either initially or on a continuing basis, to provide any Lender or the holder of any Note with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any time or times thereafter. The Administrative Agent shall not be responsible to any Lender or the holder of any Note for any recitals, statements, information, representations or warranties herein or in any document, certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of this Agreement or any other Credit Document or the financial condition of Parent and its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any other Credit Document, or the financial condition of Parent and its Subsidiaries or the existence or possible existence of any Default or Event of Default.

          12.04 Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from the Required Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Credit Document, the Administrative Agent shall be entitled to refrain from such act or taking such action unless and until the Administrative Agent shall have received instructions from the Required Lenders; and the Administrative Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, neither any Lender nor the holder of any Note shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder or under any other Credit Document in accordance with the instructions of the Required Lenders.

          12.05 Reliance. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by any Person that the Administrative Agent believed to be the proper Person, including, without limitation, counsel to Parent and its Subsidiaries, and, with respect to all legal matters pertaining to this Agreement and any other Credit Document and its duties hereunder and thereunder, upon advice and statements of legal counsel.

          12.06 Indemnification. To the extent the Administrative Agent is not reimbursed and indemnified by the Borrower, the Lenders will reimburse and indemnify the Administrative Agent, in proportion to their respective “percentages” as used in determining the Required Lenders, for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its respective duties hereunder or under any other Credit Document, in any way relating to or arising out of this Agreement or any other Credit Document; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence, willful misconduct or unlawful act.

          12.07 The Administrative Agent in Its Individual Capacity. With respect to its obligation to make Loans under this Agreement, the Administrative Agent shall have the rights and powers specified herein for a “Lender” and may exercise the same rights and powers as

though it were not performing the duties specified herein; and the term “Lenders,” “Required Lenders,” “holders of Notes” or any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. The Administrative Agent may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with Parent or its Subsidiaries or any Affiliate thereof as if it were not performing the duties specified herein, and may accept fees and other consideration from Parent or any of its Subsidiaries for services in connection with this Agreement and otherwise without having to account for the same to the Lenders.

          12.08 Holders. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes hereof unless and until a written notice of the assignment, transfer or endorsement thereof, as the case may be, shall have been filed with the Administrative Agent. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee, assignee or indorsee, as the case may be, of such Note or of any Note or Notes issued in exchange therefor.

          12.09 Resignation by the Administrative Agent. (a) The Administrative Agent may resign from the performance of all its functions and duties hereunder and/or under the other Credit Documents at any time by giving 15 Business Days’ prior written notice to the Borrower and the Lenders. Such resignation shall take effect upon the appointment of a successor Administrative Agent pursuant to clauses (b) and (c) below or as otherwise provided below.

          (b) Upon any such notice of resignation, the Required Lenders shall appoint a successor Administrative Agent hereunder or thereunder who shall be a commercial bank or trust company reasonably acceptable to the Borrower.

          (c) If a successor Administrative Agent shall not have been so appointed within such 15 Business Day period, the Administrative Agent, with the consent of the Borrower, shall then appoint a successor Administrative Agent who shall serve as Administrative Agent hereunder or thereunder until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above.

          (d) If no successor Administrative Agent has been appointed pursuant to clause (b) or (c) above by the 20th Business Day after the date such notice of resignation was given by the Administrative Agent, the Administrative Agent’s resignation shall become effective and the Required Lenders shall thereafter perform all the duties of the Administrative Agent hereunder and/or under any other Credit Document until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above.

          SECTION 13. Miscellaneous.

          13.01 Payment of Expenses, etc. The Borrower agrees to (and to cause each other Credit Party, in respect of the Credit Document to which it is a party, to): (i) whether or not the transactions herein contemplated are consummated, pay all reasonable out-of-pocket costs and expenses of the Administrative Agent in connection with the negotiation, preparation, execution and delivery of the Credit Documents and the documents and instruments referred to

therein and any amendment, waiver or consent relating thereto (including, without limitation, the reasonable fees and disbursements of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP) and of the Administrative Agent and, after the occurrence and during the continuance of an Event of Default, each of the Lenders in connection with the enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, the actual reasonable fees and disbursements of counsel for the Administrative Agent and, after the occurrence and during the continuance of an Event of Default for each of the Lenders), provided that to the extent it is feasible and a conflict of interest does not exist in the reasonable discretion of the Administrative Agent, the Lenders and their counsel, the Lenders shall use the same counsel in connection with the foregoing; (ii) pay and hold each of the Lenders harmless from and against any and all present and future stamp and other similar taxes with respect to the foregoing matters and save each of the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to such Lender) to pay such taxes; and (iii) indemnify each Lender (including in its capacity as the Administrative Agent), its officers, directors, employees, representatives and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, (a) any investigation, litigation or other proceeding (whether or not any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of the proceeds of any Loans hereunder or the consummation of any transactions contemplated in any Credit Document, whether initiated by the Borrower or any other Person, including, without limitation, the actual reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of the gross negligence, willful misconduct, unlawful act or material breach of the terms of this Agreement of the Person to be indemnified) or (b) the actual or alleged presence of Hazardous Materials in the air, surface water, groundwater, surface or subsurface of any Real Property, offshore drilling rig, vessel or other facility or location at any time owned or operated by Parent or any of its Subsidiaries, the generation, storage, transportation or disposal of Hazardous Materials at any Real Property, offshore drilling rig, vessel or other facility or location at any time owned or operated by Parent or any of its Subsidiaries, the non-compliance of any Real Property, offshore drilling rig, vessel or other facility or location at any time owned or operated by Parent or any of its Subsidiaries with federal, state and local laws, regulations, and ordinances (including applicable permits thereunder) applicable to any such Real Property, offshore drilling rig, vessel or other facility or location, or any Environmental Claim asserted against Parent, any of its Subsidiaries, or any Real Property, offshore drilling rig, vessel or other facility or location at any time owned or operated by Parent or any of its Subsidiaries, including, in each case, without limitation, the actual reasonable fees and disbursements of counsel and other consultants incurred in connection with any such investigation, litigation or other proceeding (but excluding any losses, liabilities, claims, damages or expenses to the extent incurred by reason of the gross negligence, willful misconduct, unlawful act of the Person to be indemnified. To the extent that the undertaking to indemnify, pay or hold harmless the Administrative Agent or any Lender set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, the Borrower shall make the maximum contribution to the payment and satisfaction of each of the indemnified liabilities which is permissible under applicable law.

          13.02 Right of Setoff. In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, if an Event of Default then exists, each Lender is hereby authorized at any time or from time to time, without presentment, demand, protest or other notice of any kind to the Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other Indebtedness at any time held or owing by such Lender (including without limitation by branches and agencies of such Lender wherever located) to or for the credit or the account of the Borrower against and on account of the Obligations and liabilities of the Borrower to such Lender under this Agreement or under any of the other Credit Documents, including, without limitation, all interests in Obligations of the Borrower purchased by such Lender pursuant to Section 13.06(b), and all other claims of any nature or description arising out of or connected with this Agreement or any other Credit Document, irrespective of whether or not such Lender shall have made any demand hereunder and although said Obligations, liabilities or claims, or any of them, shall be contingent or unmatured. Without limiting the foregoing, each Lender agrees to use reasonable efforts to notify the Borrower of any exercise of such Lender’s right of setoff granted hereby.

          13.03 Notices. (a) Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including telex or telecopier communication) and mailed, telexed, telecopied or delivered, if to Parent, the Borrower or its Subsidiaries, at the address specified opposite its signature below or in the other relevant Credit Documents, as the case may be; if to any Lender, at its address specified for such Lender on Annex II; or, at such other address as shall be designated by any party in a written notice to the other parties hereto. All such notices and communications shall be effective when received and, in the case of notice by telecopier, after confirmation of such receipt has been given by the recipient, excluding by way of automatic receipt produced by telecopier.

          (b) Without in any way limiting the obligation of the Borrower to confirm in writing any telephonic notice permitted to be given hereunder, the Administrative Agent, may prior to receipt of written confirmation act without liability upon the basis of such telephonic notice, believed by the Administrative Agent in good faith to be from an Authorized Officer of the Borrower. In each such case, the Borrower hereby waives the right to dispute the Administrative Agent’s record of the terms of such telephonic notice.

     13.04 Benefit of Agreement. (a) This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto, provided that no Credit Party may assign or transfer any of its rights or obligations hereunder without the prior written consent of the Lenders. Each Lender may at any time grant participations in any of its rights hereunder or under any of the Notes to another financial institution, provided that in the case of any such participation, the participant shall not have any rights under this Agreement or any of the other Credit Documents (the participant’s rights against such Lender in respect of such participation to be those set forth in the agreement executed by such Lender in favor of the participant relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation, except that the participant shall be entitled to the benefits of Sections 1.10 and 4.04 of this Agreement to the extent that such Lender would be entitled to such benefits if the participation had not been entered into or sold, and, provided further, that no Lender shall transfer, grant or

assign any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) extend the final scheduled maturity of any Loan or Note in which such participant is participating or reduce the rate or extend the time of payment of interest thereon (except in connection with a waiver of the applicability of any post-default increase in interest rates), or reduce the principal amount thereof, or increase such participant’s participating interest in any Commitment over the amount thereof then in effect (it being understood that a waiver of any Default or Event of Default or of a mandatory reduction in the Total Commitment, or a mandatory prepayment, shall not constitute a change in the terms of any Commitment) or (ii) consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement.

          (b) Notwithstanding the foregoing, (x) any Lender may assign all or a portion of its outstanding Commitment and its rights and obligations hereunder to its Affiliate or to another Lender, and (y) with the consent of the Administrative Agent and the Borrower (which consent shall not be unreasonably withheld), any Lender may assign all or a portion of its outstanding Commitment and its rights and obligations hereunder to one or more Eligible Transferees. No assignment pursuant to the immediately preceding sentence shall, to the extent such assignment is made to an institution other than one or more Lenders hereunder, be in an aggregate amount less than $10,000,000 unless the entire Commitment of the assigning Lender is so assigned. If any Lender so sells or assigns all or a part of its rights hereunder or under the Notes, any reference in this Agreement or the Notes to such assigning Lender shall thereafter refer to such Lender and to the respective assignee to the extent of their respective interests and the respective assignee shall have, to the extent of such assignment (unless otherwise provided therein), the same rights and benefits as it would if it were such assigning Lender. Each assignment pursuant to this Section 13.04(b) shall be effected by the assigning Lender and the assignee Lender executing an Assignment and Assumption Agreement. In the event of any such assignment (x) to a commercial bank or other financial institution not previously a Lender hereunder, either the assigning or the assignee Lender shall pay to the Administrative Agent a nonrefundable assignment fee of $3,500 and (y) to a Lender, either the assigning or assignee Lender shall pay to Administrative Agent a nonrefundable assignment fee of $1,500, and at the time of any assignment pursuant to this Section 13.04(b), (i) Annex I shall be deemed to be amended to reflect the Commitment of the respective assignee (which shall result in a direct reduction to the Commitment of the assigning Lender) and of the other Lenders, and (ii) if any such assignment occurs after the Closing Date, if requested by the assigning Lender and the assignee Lender, the Borrower will issue new Notes to the respective assignee and to the assigning Lender in conformity with the requirements of Section 1.05. Each Lender and the Borrower agree to execute such documents (including, without limitation, amendments to this Agreement and the other Credit Documents) as shall be necessary to effect the foregoing. Nothing in this clause (b) shall prevent or prohibit any Lender from pledging its Notes or Loans to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank.

          (c) Notwithstanding any other provisions of this Section 13.04, no transfer or assignment of the interests or obligations of any Lender hereunder or any grant of participation therein shall be permitted if such transfer, assignment or grant would require the Borrower or either Parent Guarantor to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any State.

          (d) Each Lender initially party to this Agreement hereby represents, and each Person that became a Lender pursuant to an assignment permitted by this Section 13 will, upon its becoming party to this Agreement, represent that it is a commercial lender, other financial institution or other “accredited” investor (as defined in SEC Regulation D) which makes loans in the ordinary course of its business and that it will make or acquire Loans for its own account in the ordinary course of such business, provided that subject to the preceding clauses (a) and (b), the disposition of any promissory notes or other evidences of or interests in Indebtedness held by such Lender shall at all times be within its exclusive control.

          13.05 No Waiver; Remedies Cumulative. No failure or delay on the part of the Administrative Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between Parent or any of its Subsidiaries and the Administrative Agent or any Lender shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies herein expressly provided are cumulative and not exclusive of any rights or remedies which the Administrative Agent or any Lender would otherwise have. No notice to or demand on Parent or any of its Subsidiaries in any case shall entitle Parent or any of its Subsidiaries to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent or the Lenders to any other or further action in any circumstances without notice or demand.

          13.06 Payments Pro Rata. (a) The Administrative Agent agrees that promptly after its receipt of each payment from or on behalf of Parent or any of its Subsidiaries in respect of any Obligations of Parent or any of its Subsidiaries hereunder, it shall distribute such payment to the Lenders (other than any Lender that has expressly waived its right to receive its pro rata share thereof) pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received.

          (b) Each of the Lenders agrees that, if it should receive any amount hereunder (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise) which is applicable to the payment of the principal of, or interest on, the Loans, of a sum which with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to such Lender bears to the total of such Obligation then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without recourse or warranty from the other Lenders an interest in the Obligations of Parent or any of its Subsidiaries, respectively, to such Lenders in such amount as shall result in a proportional participation by all of the Lenders in such amount, provided that if all or any portion of such excess amount is thereafter recovered from such Lender, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

          (c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 13.06(a) and (b) shall be subject to the express provisions of this Agreement which require, or permit, differing payments to be made to Non-Defaulting Lenders as opposed to Defaulting Lenders.

          13.07 Calculations; Computations. (a) The financial statements to be furnished to the Lenders pursuant hereto shall be made and prepared in accordance with GAAP consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise disclosed in writing by Parent to the Lenders), provided that (x) except all computations determining compliance with Section 9, including definitions used therein, shall utilize accounting principles and policies in effect at the time of the preparation of, and in conformity with those used to prepare, the December 31, 2004 historical financial statements of the Borrower delivered to the Lenders pursuant to Section 7.10(b), and (y) if at any time the computations determining compliance with Section 9 utilize accounting principles different from those utilized in such financial statements furnished to the Lenders, such financial statements shall be accompanied by reconciliation worksheets.

          (b) All computations of interest relating to Eurodollar Loans shall be made on the actual number of days elapsed over a year of 360 days. All other computations of interest hereunder shall be made on the actual number of days elapsed over a year of 365 days.

          13.08 Governing Law; Submission to Jurisdiction; Venue; Waiver of Jury Trial. (a) This Agreement and the other Credit Documents and the rights and obligations of the parties hereunder and thereunder shall be construed in accordance with and be governed by the law of the state of New York. Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the courts of the state of New York or of the United States for the Southern District of New York, and, by execution and delivery of this Agreement, each Credit Party party hereto hereby irrevocably accepts for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts. Each Credit Party further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to such Credit Party located outside New York City and by hand delivery to such Credit Party located within New York City, at its address for notices pursuant to Section 13.03, such service to become effective 30 days after such mailing. Nothing herein shall affect the right of the Administrative Agent, any Lender to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against any Credit Party in any other jurisdiction.

          (b) Each Credit Party hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement or any other Credit Document brought in the courts referred to in clause (a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

          (c) Each of the parties to this agreement hereby irrevocably waives all right to a trial by jury in any action, proceeding or counterclaim arising out of or relating to this agreement, the other credit documents or the transactions contemplated hereby or thereby.

          13.09 Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the

same instrument. A set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent.

          14.01 Guaranty. In order to induce the Lenders to enter into this Agreement and to extend credit hereunder and in recognition of the direct benefits to be received by each Parent Guarantor from the proceeds of the Loans, each Parent Guarantor hereby agrees with the Lenders as follows: each Parent Guarantor hereby unconditionally and irrevocably guarantees, as primary obligor and not merely as surety the full and prompt payment when due, whether upon maturity, acceleration or otherwise, of any and all of the Guaranteed Obligations to the Guaranteed Creditors. If any or all of the Guaranteed Obligations to the Guaranteed Creditors becomes due and payable hereunder, each Parent Guarantor unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, together with any and all expenses which may be incurred by the Guaranteed Creditors in collecting any of the Guaranteed Obligations. This Parent Guaranty is a continuing one and all liabilities to which it applies or

may apply under the terms hereof shall be conclusively presumed to have been created in a reliance hereon. If claim is ever made upon any Guaranteed Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property or (ii) any settlement or compromise of any such claim effected by such payee with any such claimant (including the Borrower), then and in such event each Parent Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such Parent Guarantor, notwithstanding any revocation of this Parent Guaranty or any other instrument evidencing any liability of the Borrower or any of its Subsidiaries, and each Parent Guarantor shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee.

          14.02 Bankruptcy. Additionally, each Parent Guarantor unconditionally and irrevocably guarantees the payment of any and all of the Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the Borrower upon the occurrence of any of the events specified in Section 10.05, and unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand.

          14.03 Nature of Liability. The liability of each Parent Guarantor hereunder is exclusive and independent of any security for or other guaranty of the Guaranteed Obligations whether executed by either Parent Guarantor, any other guarantor or by any other party, and the liability of each Parent Guarantor hereunder is not affected or impaired by (a) any direction as to application of payment by the Borrower or by any other party, or (b) any other continuing or other guaranty, undertaking or maximum liability of a guarantor or of any other party as to the Guaranteed Obligations, or (c) any payment on or in reduction of any such other guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by the Borrower or (e) any payment made to the Guaranteed Creditors on the Guaranteed Obligations which any such Guaranteed Creditor repays to the Borrower pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each Parent Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding.

          14.04 Independent Obligation. No invalidity, irregularity or unenforceability of all or any part of the Guaranteed Obligations or of any security therefor shall affect, impair or be a defense to this Parent Guaranty, and this Parent Guaranty shall be primary, absolute and unconditional notwithstanding the occurrence of any event or the existence of any other circumstances which might constitute a legal or equitable discharge of a surety or guarantor except payment in full of the Guaranteed Obligations. The obligations of each Parent Guarantor hereunder are independent of the obligations of the Borrower, any other guarantor or any other Person, and a separate action or actions may be brought and prosecuted against either Parent Guarantor whether or not action is brought against the Borrower, any other guarantor or any other Person and whether or not the Borrower, any other guarantor or any other Person be joined in any such action or actions. Each Parent Guarantor waives, to the full extent permitted by law, the benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof. Any

payment by the Borrower or other circumstance which operates to toll any statute of limitations as to the Borrower shall operate to toll the statute of limitations as to each Parent Guarantor.

          14.05 Authorization. Each Parent Guarantor authorizes the Guaranteed Creditors without notice or demand (except as shall be required by applicable statute and cannot be waived), and without affecting or impairing its liability hereunder, from time to time to:

     (a) change the manner, place or terms of payment of, and/or change or extend the time of payment of, renew, increase, accelerate or alter, any of the Guaranteed Obligations (including any increase or decrease in the rate of interest thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof, and this Parent Guaranty made shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

     (b) take and hold security for the payment of the Guaranteed Obligations and sell, exchange, release, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset thereagainst;

     (c) exercise or refrain from exercising any rights against the Borrower or others or otherwise act or refrain from acting;

     (d) release or substitute any one or more endorsers, guarantors, the Borrower or other obligors;

     (e) settle or compromise any of the Guaranteed Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Borrower to its creditors other than the Guaranteed Creditors;

     (f) apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of the Borrower to the Guaranteed Creditors regardless of what liability or liabilities of the Borrower remain unpaid;

     (g) consent to or waive any breach of, or any act, omission or default under, this Agreement, any other Credit Document or any of the instruments or agreements referred to herein or therein, or otherwise amend, modify or supplement any Credit Document (other than this Agreement) or any of such other instruments or agreements; and/or

     (h) take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of either Parent Guarantor from its liabilities under this Parent Guaranty.

          14.06 Reliance. It is not necessary for the Guaranteed Creditors to inquire into the capacity or powers of the Borrower or the officers, directors, partners or agents acting or

purporting to act on its behalf, and any Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

          14.07 Subordination. Any of the indebtedness of the Borrower now or hereafter owing to either Parent Guarantor is hereby subordinated to the Guaranteed Obligations of the Borrower owing to the Guaranteed Creditors; and if the Administrative Agent so requests at a time when an Event of Default exists, all such indebtedness of the Borrower to such Parent Guarantor shall be collected, enforced and received by such Parent Guarantor for the benefit of the Guaranteed Creditors and be paid over to the Administrative Agent on behalf of the Guaranteed Creditors on account of the Guaranteed Obligations of the Borrower to the Guaranteed Creditors, but without affecting or impairing in any manner the liability of such Parent Guarantor under the other provisions of this Parent Guaranty. Prior to the transfer by a Parent Guarantor of any note or negotiable instrument evidencing any of the indebtedness of the Borrower to such Parent Guarantor, such Parent Guarantor shall ▇▇▇▇ such note or negotiable instrument with a legend that the same is subject to this subordination. Without limiting the generality of the foregoing, each Parent Guarantor hereby agrees with the Guaranteed Creditors that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this Parent Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash.

          14.08 Waiver. (a) Each Parent Guarantor waives any right (except as shall be required by applicable statute and cannot be waived) to require any Guaranteed Creditor to (i) proceed against the Borrower, any other guarantor or any other party, (ii) proceed against or exhaust any security held from the Borrower, any other guarantor or any other party or (iii) pursue any other remedy in any Guaranteed Creditor’s power whatsoever. Each Parent Guarantor waives any defense based on or arising out of any defense of the Borrower, any other guarantor or any other party, other than payment in full of the Guaranteed Obligations, based on or arising out of the disability of the Borrower, any other guarantor or any other party, or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrower other than payment in full of the Guaranteed Obligations. The Guaranteed Creditors may, at their election, foreclose on any security held by the Administrative Agent or any other Guaranteed Creditor by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise any other right or remedy the Guaranteed Creditors may have against the Borrower or any other party, or any security, without affecting or impairing in any way the liability of either Parent Guarantor hereunder except to the extent the Guaranteed Obligations have been paid. Each Parent Guarantor waives any defense arising out of any such election by the Guaranteed Creditors, even though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of such Parent Guarantor against the Borrower or any other party or any security.

          (b) Each Parent Guarantor waives all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Parent Guaranty, and notices of the existence, creation or incurring of new or additional Guaranteed Obligations. Each Parent Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s financial

condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which each Parent Guarantor assumes and incurs hereunder, and agrees that the Guaranteed Creditors shall have no duty to advise either Parent Guarantor of information known to them regarding such circumstances or risks.

          (c) Until such time as the Guaranteed Obligations have been paid in full in cash or Cash Equivalents, each Parent Guarantor hereby waives all rights of subrogation which it may at any time otherwise have as a result of this Parent Guaranty (whether contractual, under Section 509 of the Bankruptcy Code, or otherwise) to the claims of the Guaranteed Creditors against the Borrower or any other guarantor of the Guaranteed Obligations and all contractual, statutory or common law rights of reimbursement, contribution or indemnity from the Borrower or any other guarantor which it may at any time otherwise have as a result of this Parent Guaranty.

          14.09 Payment. All payments made by either Parent Guarantor pursuant to this Section 14 will be made without setoff, counterclaim or other defense, and shall be subject to the provisions of Sections 4.03 and 4.04.
