Exhibit 10.1

AMENDMENT AGREEMENT dated as of April 14, 2005 (this “Amendment”), to the First Lien Credit Agreement dated as of March 29, 2004, as amended by Amendment ▇▇. ▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ and Agreement dated as of September 24, 2004 (the “Existing Credit Agreement”), among ATP OIL & GAS CORPORATION (the “Borrower”), the lenders from time to time party thereto (the “Lenders”) and CREDIT SUISSE FIRST BOSTON, as administrative agent (in such capacity, the “Administrative Agent”) and as collateral agent (in such capacity, the “Collateral Agent”) for the Lenders.

A. The Borrower has requested that the Existing Credit Agreement be amended to, among other things, provide for New Term Loans, the proceeds of which will be used as specified in the preliminary statement to the Restated Credit Agreement (as defined below).

B. Each Lender with outstanding Existing Term Loans (each, an “Existing Lender”) will be afforded the opportunity to acquire New Term Loans on the Restatement Date (as defined below) in an aggregate principal amount equal to the aggregate principal amount of the outstanding Existing Term Loans of such Existing Lender on the Restatement Date. Each Existing Lender that executes and delivers a signature page to this Amendment under the caption “Continuing Lender” (each, a “Continuing Lender”) at or prior to 12:00 (noon), New York City time, on April 14, 2005 (the “Signing Date”) will be deemed to have agreed to the terms of this Amendment and to so acquire New Term Loans in such aggregate principal amount, in each case upon the effectiveness of this Amendment on the Restatement Date. Each Existing Lender that does not execute and deliver a signature page to this Amendment at or prior to the Signing Date (each such Existing Lender, a “Departing Lender”) will be deemed not to have agreed to this Amendment, and the Borrower will repay or cause to be repaid the outstanding principal amount of such Existing Lender’s Existing Term Loans upon the effectiveness of this Amendment on the Restatement Date. The Existing Term Loans of Continuing Lenders shall be deemed to have been repaid in full upon the exchange thereof for New Term Loans in the same aggregate principal amount on the Restatement Date.

C. Each person (other than a Continuing Lender in its capacity as such) that agrees to make New Term Loans (each, an “Additional Lender”) will, on the Restatement Date, make such New Term Loans to the Borrower in the manner contemplated by Section 1 hereof.

D. The Continuing Lenders and the Additional Lenders are willing to so acquire and make, respectively, the New Term Loans to the Borrower on the Restatement Date, subject to the terms and conditions and for the purposes set forth herein and in the Restated Credit Agreement.

E. The Borrower and the Requisite Lenders (as defined below) desire to amend and restate the Existing Credit Agreement in the form of the Amended and Restated Credit Agreement attached hereto as Exhibit A (the “Restated Credit Agreement”) to, among other things, set forth the terms and conditions under which the Continuing Lenders and the Additional Lenders will acquire and make, respectively, the New Term Loans to the Borrower, and to make certain other amendments thereto.

F. The amendment and restatement of the Existing Credit Agreement evidenced by the Restated Credit Agreement is subject to the satisfaction of the conditions precedent to effectiveness referred to in Section 5 hereof and shall become effective as provided in Section 6 hereof.

G. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Restated Credit Agreement.

Accordingly, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. New Term Loans. (a) Subject to the terms and conditions set forth herein and in the Restated Credit Agreement, as of the Restatement Date, (i) each Continuing Lender agrees to exchange its Existing Term Loans for New Term Loans of like outstanding principal amount (such New Term Loans, the “Rollover Term Loans”) and (ii) each Additional Lender agrees to make New Term Loans to the Borrower in amounts equal to the amount of New Term Loans such person commits to make on the Restatement Date as set forth on the signature page of such person to this Amendment. For purposes hereof, a person shall become an Additional Lender and a party to the Restated Credit Agreement by executing and delivering to the Administrative Agent, on or prior to the Signing Date, a signature page to this Amendment setting forth the amount of New Term Loans such person commits to make on the Restatement Date.

(b) Each Continuing Lender shall be deemed to have acquired its Rollover Term Loans on the Restatement Date in exchange for its Existing Term Loans. Each Additional Lender shall fund the proceeds of its New Term Loans to the Administrative Agent on the Restatement Date, in the manner contemplated by the Restated Credit Agreement (including Section 2.02 thereof).

(c) The commitments of the Additional Lenders and the exchange undertakings of the Continuing Lenders are several and no such Lender shall be responsible for any other Lender’s failure to make or acquire by exchange any New Term Loans.

(d) The obligations of each Continuing Lender and each Additional Lender to acquire or make New Term Loans on the Restatement Date are subject to (i) the satisfaction or waiver in accordance with the Restated Credit Agreement of each of the conditions in Article IV of the Restated Credit Agreement and (ii) this Amendment having become effective in accordance with Section 6 hereof.

(e) On the Restatement Date, the Borrower shall apply (and hereby irrevocably directs the Administrative Agent, pursuant to Section 2.12 of the Restated Credit Agreement, to so apply) a sufficient amount of the cash proceeds of the New Term Loans to (i) prepay in full the Existing Term Loans of the Departing Lenders, (ii) pay all accrued and unpaid interest on all such Existing Term Loans to but excluding the Restatement Date, and (iii) pay to each Departing Lender all amounts payable pursuant to Section 2.12(b) of the Existing Credit Agreement, and pay to each Departing Lender and each Existing Lender all amounts (if any) payable pursuant to Section 2.16 of the Existing Credit Agreement, in each case as a result of the prepayment of such Lender’s Existing Term Loans on the Restatement Date.

(f) The Requisite Lenders hereby waive the requirements of Sections 2.02, 2.12 (other than the last sentence of Section 2.12(d) thereof), 2.17 and 2.19 of the Restated Credit Agreement, to the extent they relate to the borrowings and prepayments contemplated by this Amendment.

(g) On the Restatement Date, each Departing Lender, to the extent of the repayment as contemplated by Section 1(e) above, shall cease to be a party to the Existing Credit Agreement and shall be released from all further obligations thereunder and shall have no further rights to or interest in any of the Collateral; provided, however, that notwithstanding that the Existing Term Loans shall be refinanced in full on the Restatement Date, the provisions of the Existing Credit Agreement as in effect immediately prior to the Restatement Date with respect to indemnification, reimbursement of costs and expenses, increased costs and break funding payments will continue in full force and effect with respect to, and for the benefit of, each Existing Lender in respect of such Lender’s Existing Term Loans existing under the Existing Credit Agreement prior to the Restatement Date.

SECTION 2. Amendment and Restatement of the Existing Credit Agreement. The Borrower and the Requisite Lenders agree that the Existing Credit Agreement (including all exhibits and schedules thereto) shall be amended and restated on the Restatement Date such that, on the Restatement Date, the terms set forth in the Restated Credit Agreement shall replace the terms of the Existing Credit Agreement (with Schedule 2.01 being modified to set forth the Continuing Lenders and the Additional Lenders and their respective Term Loan Commitments). As used in the Restated Credit Agreement, the terms “Agreement”, “this Agreement”, “herein”, “hereinafter”, “hereto”, “hereof”, and words of similar import shall, unless the context otherwise requires, mean, from and after the replacement of the terms of the Existing Credit Agreement by the terms of the Restated Credit Agreement, the Restated Credit Agreement.

SECTION 3. Amendment Fee. The Borrower agrees to pay to the Administrative Agent for the account of each Continuing Lender that executes and delivers a signature page to this Amendment in its capacity as such to the Administrative Agent (or its counsel) at or prior to the Signing Date, an amendment fee (the “Amendment Fee”) in an amount equal to 2.00% of the aggregate principal amount of the Rollover Term Loans of such Continuing Lender. The Amendment Fee shall be payable in immediately available funds on the Restatement Date. Once paid, the Amendment Fee shall not be refundable.

SECTION 4. Representations and Warranties. To induce the other parties hereto to enter into this Amendment, the Borrower represents and warrants to the Administrative Agent, the Collateral Agent and each of the Lenders that, as of the Restatement Date:

(a) This Amendment has been duly authorized, executed and delivered by the Borrower and the Restated Credit Agreement, as amended hereby, constitutes a legal, valid and binding obligation of the Borrower.

(b) The representations and warranties set forth in Article III of the Restated Credit Agreement are true and correct in all material respects on and as of the Restatement Date with the same effect as though made on and as of the Restatement Date, except to the extent such representations and warranties expressly relate to an earlier date (in which case such representations and warranties were true and correct in all material respects as of such earlier date).

SECTION 5. Conditions to the Effectiveness of the Restated Credit Agreement. The Restated Credit Agreement shall become effective on the date on which (i) each of the conditions in Article IV of the Restated Credit Agreement is satisfied or waived in accordance with the Restated Credit Agreement and (ii) this Amendment shall have become effective in accordance with Section 6 hereof.

SECTION 6. Effectiveness; Amendment. This Amendment shall become effective as of the date first set forth above on the date (the “Restatement Date”) on which (a) the Administrative Agent shall have received the Amendment Fee and (b) the Administrative Agent (or its counsel) shall have received counterparts of this Amendment that, when taken together, bear the signatures of the Borrower, the Administrative Agent and the Requisite Lenders. As used herein, the term “Requisite Lenders” shall mean (x) each Continuing Lender and (y) Additional Lenders that have committed to make New Term Loans on the Restatement Date (as set forth on the signature pages to this Amendment of such Additional Lenders) in an aggregate amount that is equal to at least $350,000,000 less the aggregate amount of the Rollover Term Loans. This Amendment may not be amended nor may any provision hereof be waived except pursuant to a writing signed by each of the parties hereto.

SECTION 7. No Novation. Neither this Amendment nor the effectiveness of the Restated Credit Agreement shall extinguish the obligations for the payment of money outstanding under the Existing Credit Agreement or discharge or release the Lien or priority of any Loan Document or any other security therefor or any guarantee thereof, except as expressly provided for herein with respect to the prepayment of the Existing Term Loans of the Departing Lenders. Except with respect to such prepayment, nothing herein contained shall be construed as a substitution or novation of the Obligations outstanding under the Existing Credit Agreement or instruments guaranteeing or securing the same, which shall remain in full force and effect, except as modified hereby or by instruments executed concurrently herewith. Nothing expressed or implied in this Amendment, the Restated Credit Agreement or any other document contemplated hereby or thereby shall be construed as a release or other discharge of the Borrower under the Existing Credit Agreement or the Borrower or any other Loan Party under any Loan Document (as defined in the Existing Credit Agreement) from any of its obligations and liabilities thereunder. The Existing Credit Agreement and each of the other Loan Documents (as defined in the Existing Credit Agreement) shall remain in full force and effect, until and except as modified hereby or thereby in connection herewith or therewith. This Amendment shall constitute a Loan Document for all purposes of the Existing Credit Agreement and the Restated Credit Agreement.

SECTION 8. Applicable Law. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 9. Counterparts. This Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 6 hereof. Delivery of an executed signature page to this Amendment by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Amendment.

SECTION 10. Headings. The headings of this Amendment are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.

SECTION 11. Expenses. The Borrower agrees to reimburse the Administrative Agent for all reasonable out-of-pocket expenses incurred in connection with this Amendment, including the reasonable fees, charges and disbursements of Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Administrative Agent.

AMENDED AND RESTATED CREDIT AGREEMENT dated as of April 14, 2005, among ATP OIL & GAS CORPORATION, a Texas corporation (the “Borrower”), the Lenders (as defined in Article I), and CREDIT SUISSE FIRST BOSTON, as administrative agent (in such capacity, the “Administrative Agent”) and as collateral agent (in such capacity, the “Collateral Agent”) for the Lenders.

The Borrower, the Administrative Agent, the Collateral Agent and the lenders party thereto (the “Existing Lenders”) previously entered into the First Lien Credit Agreement dated as of March 29, 2004, as amended by Amendment ▇▇. ▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ and Agreement dated as of September 24, 2004 (the “Existing Credit Agreement”), under which the Existing Lenders extended credit to the Borrower in the form of term loans in an aggregate principal amount of $185,000,000 (of which $183,237,500 aggregate principal amount (the “Existing Term Loans”) is outstanding immediately prior to the Restatement Date (such term and each other capitalized term used but not defined in this introductory statement having the meaning given it in Article I)).

The Borrower has requested that the Lenders agree to make New Term Loans to the Borrower on the Restatement Date, in an aggregate principal amount not in excess of $350,000,000 (including the amount of Existing Term Loans exchanged for New Term Loans as provided for in the Amendment Agreement), the proceeds of which will be used by the Borrower (a) to prepay the Existing Term Loans, together with accrued and unpaid interest thereon, to the extent such Existing Term Loans are not exchanged for New Term Loans as provided for in the Amendment Agreement, (b) to prepay all amounts due or outstanding under the Second Lien Credit Agreement and (c) to pay fees and expenses incurred in connection with the Transactions. The remaining proceeds of the New Term Loans are to be used from time to time solely for general corporate purposes.

The Lenders are willing to extend such credit to the Borrower on the terms and subject to the conditions set forth herein and in the Amendment Agreement.

The Borrower and the Lenders desire to amend and restate the Existing Credit Agreement in the form hereof to, among other things, set forth the terms and conditions under which the Lenders will make the New Term Loans to the Borrower and make certain other amendments thereto.

The amendment and restatement of the Existing Credit Agreement evidenced by this Agreement shall become effective as provided in the Amendment Agreement.

Accordingly, the parties hereto agree as follows:

“Amendment Agreement” shall mean the Amendment Agreement dated as of April 14, 2005, effecting, among other things, the amendment and restatement of the Existing Credit Agreement.

“Business Day” shall mean any day other than a Saturday, Sunday or day on which banks in New York City are authorized or required by law to close; provided, however, that when used in connection with a Eurodollar Loan, the term “Business Day” shall also exclude any day on which banks are not open for dealings in dollar deposits in the London interbank market.

“Capital Expenditures” shall mean, for any period, (a) the additions to property, plant and equipment and other capital expenditures of the Borrower and its consolidated Subsidiaries that are (or should be) set forth in a consolidated statement of cash flows of the Borrower for such period prepared in accordance with GAAP and (b) Capital Lease Obligations or Synthetic Lease Obligations incurred by the Borrower and its consolidated Subsidiaries during such period, but excluding in each case any such expenditure made to restore, replace or rebuild property to the condition of such property immediately prior to any damage, loss, destruction or condemnation of such property, to the extent such expenditure is made with insurance proceeds, condemnation awards or damage recovery proceeds relating to any such damage, loss, destruction or condemnation.

“Capital Lease Obligations” of any person shall mean the obligations of such person to pay rent or other amounts under any lease of (or other arrangement conveying the right to use) real or personal property, or a combination thereof, which obligations are required to be classified and accounted for as capital leases on a balance sheet of such person under GAAP, and the amount of such obligations shall be the capitalized amount thereof determined in accordance with GAAP.

Amounts paid or prepaid in respect of Term Loans may not be reborrowed.

SECTION 2.02. Loans. (a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their applicable Commitments; provided, however, that the failure of any Lender to make any Loan shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender).

(b) Subject to Sections 2.08 and 2.15, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request pursuant to Section 2.03. Each Lender may at its option make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. Borrowings of more than one Type may be outstanding at the same time; provided, however, that the Borrower shall not be entitled to request any Borrowing that, if made, would result in more than six Eurodollar Borrowings outstanding hereunder at any time. For purposes of the foregoing, Borrowings having different Interest Periods, regardless of whether they commence on the same date, shall be considered separate Borrowings.

(c) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds to such account in New York City as the Administrative Agent may designate not later than 1:00 p.m., New York City time, on such date, and the Administrative Agent shall promptly credit the amounts so received to an account designated by the Borrower in the applicable Borrowing Request or, if a Borrowing shall not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so received to the respective Lenders.

(d) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (c) above and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If the Administrative Agent shall have so made funds available then, to the extent that such Lender shall not have made such portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, (A) for the first two days following the date such amount is made available to the Borrower, a rate determined by the Administrative Agent to represent its cost of overnight or short-term funds (which determination shall be conclusive absent manifest error) and (B) thereafter, at the Alternate Base Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement.

If no election as to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is specified in any such notice, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. The Administrative Agent shall promptly advise the applicable Lenders of any notice given pursuant to this Section 2.03 (and the contents thereof), and of each Lender’s portion of the requested Borrowing.

(d) The entries made in the accounts maintained pursuant to paragraphs (b) and (c) above shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, 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 obligations of the Borrower to repay the Loans in accordance with their terms.

(e) Any Lender may request that Loans made by it hereunder be evidenced by a promissory note. In such event, the Borrower shall execute and deliver to such Lender a promissory note payable to such Lender and its registered assigns and in a form and substance reasonably acceptable to the Administrative Agent and the Borrower.

The applicable Alternate Base Rate or Adjusted LIBO Rate for each Interest Period or day within an Interest Period, as the case may be, shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.07. Default Interest. If the Borrower shall default in the payment of any principal of or interest on any Loan or any other amount due hereunder, by acceleration or

otherwise, or under any other Loan Document, then, until such defaulted amount shall have been paid in full, to the extent permitted by law, all amounts outstanding under this Agreement and the other Loan Documents shall bear interest (after as well as before judgment), payable on demand, (a) in the case of principal, at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus 2.00% per annum and (b) in all other cases, at a rate per annum (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when determined by reference to the Prime Rate and over a year of 360 days at all other times) equal to the rate that would be applicable to an ABR Loan plus 2.00% per annum.

SECTION 2.08. Alternate Rate of Interest. In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurodollar Borrowing the Administrative Agent shall have determined that dollar deposits in the principal amounts of the Loans comprising such Borrowing are not generally available in the London interbank market, or that the rates at which such dollar deposits are being offered will not adequately and fairly reflect the cost to any Lender of making or maintaining its Eurodollar Loan during such Interest Period, or that reasonable means do not exist for ascertaining the Adjusted LIBO Rate, the Administrative Agent shall, as soon as practicable thereafter, give written or fax notice of such determination to the Borrower and the Lenders. In the event of any such determination, until the Administrative Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, any request by the Borrower for a Eurodollar Borrowing pursuant to Section 2.03 or 2.10 shall be deemed to be a request for an ABR Borrowing. Each determination by the Administrative Agent under this Section 2.08 shall be conclusive absent manifest error.

SECTION 2.09. Termination of Commitments. The Term Loan Commitments shall automatically terminate upon the making of the New Term Loans on the Restatement Date.

SECTION 2.10. Conversion and Continuation of Borrowings. The Borrower shall have the right at any time upon prior irrevocable notice to the Administrative Agent not later than 12:00 (noon), New York City time, (a) one Business Day prior thereto, to convert any Eurodollar Borrowing into an ABR Borrowing, (b) three Business Days prior thereto, to convert any ABR Borrowing into a Eurodollar Borrowing or to continue any Eurodollar Borrowing as a Eurodollar Borrowing for an additional Interest Period, and (c) three Business Days prior thereto, to convert the Interest Period with respect to any Eurodollar Borrowing to another permissible Interest Period, subject in each case to the following:

(i) each conversion or continuation shall be made pro rata among the Lenders in accordance with the respective principal amounts of the Loans comprising the converted or continued Borrowing;

(ii) if less than all the outstanding principal amount of any Borrowing shall be converted or continued, then each resulting Borrowing shall satisfy the limitations specified in Section 2.02(b) regarding the principal amount and maximum number of Borrowings of the relevant Type;

(iii) each conversion shall be effected by each Lender and the Administrative Agent by recording for the account of such Lender the new Loan of such Lender resulting

from such conversion and reducing the Loan (or portion thereof) of such Lender being converted by an equivalent principal amount; accrued interest on any Eurodollar Loan (or portion thereof) being converted shall be paid by the Borrower at the time of conversion;

(iv) if any Eurodollar Borrowing is converted at a time other than the end of the Interest Period applicable thereto, the Borrower shall pay, upon demand, any amounts due to the Lenders pursuant to Section 2.16;

(v) any portion of a Borrowing maturing or required to be repaid in less than one month may not be converted into or continued as a Eurodollar Borrowing;

(vi) any portion of a Eurodollar Borrowing that cannot be converted into or continued as a Eurodollar Borrowing by reason of the immediately preceding clause shall be automatically converted at the end of the Interest Period in effect for such Borrowing into an ABR Borrowing;

(vii) no Interest Period may be selected for any Eurodollar Borrowing that would end later than a Repayment Date occurring on or after the first day of such Interest Period if, after giving effect to such selection, the aggregate outstanding amount of (A) the Eurodollar Borrowings with Interest Periods ending on or prior to such Repayment Date and (B) the ABR Borrowings would not be at least equal to the principal amount of Borrowings to be paid on such Repayment Date; and

(viii) upon notice to the Borrower from the Administrative Agent given at the request of the Required Lenders, after the occurrence and during the continuance of a Default or Event of Default, no outstanding Loan may be converted into, or continued as, a Eurodollar Loan.

Each notice pursuant to this Section 2.10 shall be irrevocable and shall refer to this Agreement and specify (i) the identity and amount of the Borrowing that the Borrower requests be converted or continued, (ii) whether such Borrowing is to be converted to or continued as a Eurodollar Borrowing or an ABR Borrowing, (iii) if such notice requests a conversion, the date of such conversion (which shall be a Business Day) and (iv) if such Borrowing is to be converted to or continued as a Eurodollar Borrowing, the Interest Period with respect thereto. If no Interest Period is specified in any such notice with respect to any conversion to or continuation as a Eurodollar Borrowing, the Borrower shall be deemed to have selected an Interest Period of one month’s duration. The Administrative Agent shall advise the Lenders of any notice given pursuant to this Section 2.10 and of each Lender’s portion of any converted or continued Borrowing. If the Borrower shall not have given notice in accordance with this Section 2.10 to continue any Borrowing into a subsequent Interest Period (and shall not otherwise have given notice in accordance with this Section 2.10 to convert such Borrowing), such Borrowing shall, at the end of the Interest Period applicable thereto (unless repaid pursuant to the terms hereof), automatically be continued into an ABR Borrowing.

SECTION 2.11. Repayment of Borrowings. (a) The Borrower shall pay to the Administrative Agent, for the account of the Lenders, on the dates set forth below, or if any such date is not a Business Day, on the next preceding Business Day (each such date being called a

“Repayment Date”), a principal amount of the Loans (as adjusted from time to time pursuant to Sections 2.11(b), 2.12 and 2.13(e)) equal to the amount set forth below for such date, together in each case with accrued and unpaid interest on the principal amount to be paid to but excluding the date of such payment:

(c) To the extent not previously paid, all Loans shall be due and payable on the Maturity Date, together with accrued and unpaid interest on the principal amount to be paid to but excluding the date of payment.

(d) All repayments pursuant to this Section 2.11 shall be subject to Section 2.16, but shall otherwise be without premium or penalty.

SECTION 2.12. Optional Prepayment. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon written or fax notice (or telephone notice promptly confirmed by written or fax notice) at least one Business Day prior to the date of prepayment to the Administrative Agent before 12:00 (noon), New York City time; provided, however, that each partial prepayment shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000.

(b) Optional prepayments of Loans at any time during the applicable periods set forth in this Section 2.12(b) shall be accompanied by a payment of a prepayment fee in an amount (expressed as a percentage of the principal amount of the Loans to be repaid) equal to (i) 3.00%, if such prepayment occurs on or prior to ▇▇▇▇▇ ▇▇, ▇▇▇▇, (▇▇) 2.00%, if such prepayment occurs after March 31, 2006, but on or prior to March 31, 2007, and (iii) 1.00%, if such prepayment occurs after March 31, 2007, but on or prior to March 31, 2008.

(c) Optional prepayments of Loans shall be applied pro rata against the remaining scheduled installments of principal due in respect of the Loans under Section 2.11.

(d) Each notice of prepayment shall specify the prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such Borrowing by the amount stated therein on the date stated therein. All prepayments under this Section 2.12 shall be subject to Section 2.16 but otherwise without premium or penalty, except as provided in Section 2.12(b). All prepayments under this Section 2.12 shall be accompanied by accrued and unpaid interest on the principal amount to be prepaid to but excluding the date of payment.

SECTION 2.13. Mandatory Prepayments. (a) Not later than the third Business Day following the receipt of Net Cash Proceeds in respect of any Asset Sale, the Borrower shall apply 100% of the Net Cash Proceeds received with respect thereto to prepay outstanding Loans in accordance with Section 2.13(e).

(b) In the event and on each occasion that an Equity Issuance occurs, the Borrower shall, substantially simultaneously with (and in any event not later than the third Business Day next following) the occurrence of such Equity Issuance, apply 50% of the Net Cash Proceeds therefrom to prepay outstanding Loans in accordance with Section 2.13(e); provided, however, that if at the time of such Equity Issuance the Leverage Ratio (after giving effect to such Equity Issuance and the proposed use of the proceeds thereof) would be less than 2.5 to 1.0, then the amount required to be so applied shall be reduced to 25% of such Net Cash Proceeds.

(c) No later than the earlier of (i) 90 days after the end of each fiscal year of the Borrower, commencing with the fiscal year ending on December 31, 2005, and (ii) the date on which the financial statements with respect to such period are delivered pursuant to Section 5.04(a), the Borrower shall prepay outstanding Loans in accordance with Section 2.13(e) in an aggregate principal amount equal to 75% of Excess Cash Flow in excess of $5,000,000 for the fiscal year then ended; provided, however, that in the event the Leverage Ratio at the end of such fiscal year was less than 2.5 to 1.0, then such amount shall be reduced to 50% of such Excess Cash Flow in excess of $5,000,000.

(d) In the event that any Loan Party or any subsidiary of a Loan Party shall receive Net Cash Proceeds from the issuance of Indebtedness for money borrowed or consisting of Disqualified Capital Stock of any Loan Party or any subsidiary of a Loan Party (other than Indebtedness for money borrowed or consisting of Disqualified Capital Stock permitted pursuant to Section 6.01), the Borrower shall, substantially simultaneously with (and in any event not later than the third Business Day next following) the receipt of such Net Cash Proceeds by such Loan Party or such subsidiary, apply an amount equal to 100% of such Net Cash Proceeds to prepay outstanding Term Loans in accordance with Section 2.13(e).

(e) Mandatory prepayments of outstanding Loans under this Agreement shall be applied pro rata against the remaining scheduled installments of principal due in respect of the Loans under Section 2.11. All such mandatory prepayments shall be applied to all Loans outstanding on the date of prepayment on a pro rata basis.

(f) The Borrower shall deliver to the Administrative Agent, at the time of each prepayment required under this Section 2.13, (i) a certificate signed by a Financial Officer of the Borrower setting forth in reasonable detail the calculation of the amount of such prepayment and (ii) to the extent practicable, at least three days prior written notice of such prepayment. Each notice of prepayment shall specify the prepayment date, the Type of each Loan being prepaid and the principal amount of each Loan (or portion thereof) to be prepaid. All prepayments of Borrowings under this Section 2.13 shall be subject to Section 2.16, but shall otherwise be without premium or penalty.

(g) Notwithstanding the foregoing, any Lender may elect, by written notice to the Administrative Agent at least two Business Days prior to the applicable prepayment date, to decline all (but not less than all) of any mandatory prepayment of its Loans pursuant to this Section 2.13, in which case the aggregate amount of the prepayment that would have been applied to prepay Loans but was so declined shall be retained by the Borrower.

SECTION 2.14. Reserve Requirements; Change in Circumstances. (a) Notwithstanding any other provision of this Agreement, if any Change in Law shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender (except any such reserve requirement which is reflected in the Adjusted LIBO Rate) or shall impose on such Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender, and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), in each case, by an amount deemed by such Lender to be material, then the Borrower will pay to such Lender upon demand such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) If any Lender shall have determined that any Change in Law regarding capital adequacy has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender pursuant hereto to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as applicable, as specified in paragraph (a) or (b) above shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same.

(d) Failure or delay on the part of any Lender to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be under any obligation to compensate any Lender under paragraph (a) or (b) above with respect to increased costs or reductions with respect to any period prior to the date that is 120 days prior to such request if such Lender knew or could reasonably have been expected to know of the circumstances giving rise to such increased costs or reductions and of the fact that such circumstances would result in a claim for increased compensation by reason of such increased costs or reductions; provided further that the foregoing limitation shall not apply to any increased costs or reductions arising out of the retroactive application of any Change in Law within such 120-day period. The protection of this Section shall be available to each Lender regardless of any possible contention of the invalidity or inapplicability of the Change in Law that shall have occurred or been imposed.

SECTION 2.15. Change in Legality. (a) Notwithstanding any other provision of this Agreement, if any Change in Law shall make it unlawful for any Lender to make or maintain any Eurodollar Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by written notice to the Borrower and to the Administrative Agent:

(i) such Lender may declare that Eurodollar Loans will not thereafter (for the duration of such unlawfulness) be made by such Lender hereunder (or be continued for additional Interest Periods and ABR Loans will not thereafter (for such duration) be converted into Eurodollar Loans), whereupon any request for a Eurodollar Borrowing (or to convert an ABR Borrowing to a Eurodollar Borrowing or to continue a Eurodollar Borrowing for an additional Interest Period) shall, as to such Lender only, be deemed a request for an ABR Loan (or a request to continue an ABR Loan as such for an additional Interest Period or to convert a Eurodollar Loan into an ABR Loan, as the case may be), unless such declaration shall be subsequently withdrawn; and

(ii) such Lender may require that all outstanding Eurodollar Loans made by it be converted to ABR Loans, in which event all such Eurodollar Loans shall be automatically converted to ABR Loans as of the effective date of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Loans that would have been made by such Lender or the converted Eurodollar Loans of such Lender shall instead be applied to repay the ABR Loans made by such Lender in lieu of, or resulting from the conversion of, such Eurodollar Loans.

(b) For purposes of this Section 2.15, a notice to the Borrower by any Lender shall be effective as to each Eurodollar Loan made by such Lender, if lawful, on the last day of the Interest Period then applicable to such Eurodollar Loan; in all other cases such notice shall be effective on the date of receipt by the Borrower.

SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender against any loss or expense that such Lender sustains or incurs as a consequence of (a) any event, other than a default by such Lender in the performance of its obligations hereunder, which results in (i) such Lender receiving or being deemed to receive any amount on account of the principal of any Eurodollar Loan prior to the end of the Interest Period in effect therefor, (ii) the conversion of any Eurodollar Loan to an ABR Loan, or the conversion of the Interest Period with respect to any Eurodollar Loan, in each case other than on the last day of the Interest Period in effect therefor, or (iii) any Eurodollar Loan to be made by such Lender (including any Eurodollar Loan to be made pursuant to a conversion or continuation under Section 2.10) not being made after notice of such Loan shall have been given by the Borrower hereunder (any of the events referred to in this clause (a) being called a “Breakage Event”) or (b) any default in the making of any payment or prepayment required to be made hereunder. In the case of any Breakage Event, such loss shall include an amount equal to the excess, as reasonably determined by such Lender, of (i) its cost of obtaining funds for the Eurodollar Loan that is the subject of such Breakage Event for the period from the date of such Breakage Event to the last day of the Interest Period in effect (or that would have been in effect) for such Loan over (ii) the amount of interest likely to be realized by such Lender in redeploying the funds released or not utilized by reason of such Breakage Event for such period. A certificate of any Lender setting forth any amount or amounts which such Lender is entitled to receive pursuant to this Section 2.16 shall be delivered to the Borrower and shall be conclusive absent manifest error.

SECTION 2.17. Pro Rata Treatment. Except as required under Section 2.15 and in respect of any election made pursuant to Section 2.13(g), each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of any prepayment fee, each reduction of the Commitments and each conversion of any Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall be allocated pro rata among the Lenders in accordance with their respective Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans). Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount.

SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against the Borrower or any other Loan Party, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Loan or Loans as a result of which the unpaid principal portion of its Loans shall be proportionately less than the unpaid principal portion of the Loans of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other

Lender the purchase price for, a participation in the Loans of such other Lender, so that the aggregate unpaid principal amount of the Loans and participations in Loans held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all Loans then outstanding as the principal amount of its Loans prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal amount of all Loans outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this Section 2.18 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in a Loan deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such Lender by reason thereof as fully as if such Lender had made a Loan directly to the Borrower in the amount of such participation.

SECTION 2.19. Payments. (a) The Borrower shall make each payment (including principal of or interest on any Borrowing or any fees or other amounts) hereunder and under any other Loan Document not later than 12:00 (noon), New York City time, on the date when due in immediately available dollars, without setoff, defense or counterclaim. Each such payment shall be made to the Administrative Agent at its offices at Eleven ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇.

(b) Except as otherwise expressly provided herein, whenever any payment (including principal of or interest on any Borrowing or any fees or other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or fees, if applicable.

SECTION 2.20. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower or any other Loan Party hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any other Loan Party shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or such Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Loan Party shall make such deductions and (iii) the Borrower or such Loan Party shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any

payment by or on account of any obligation of the Borrower or any other Loan Party hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its behalf or on behalf of a Lender, shall be conclusive absent manifest error.

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

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

SECTION 2.21. Assignment of Commitments or Loans Under Certain Circumstances; Duty to Mitigate. (a) In the event (i) any Lender delivers a certificate requesting compensation pursuant to Section 2.14, (ii) any Lender delivers a notice described in Section 2.15, (iii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority on account of any Lender pursuant to Section 2.20 or (iv) any Lender refuses to consent to any amendment, waiver or other modification of any Loan Document requested by the Borrower that requires the consent of a greater percentage of the Lenders than the Required Lenders and such amendment, waiver or other modification is consented to by the Required Lenders, the Borrower may, at its sole expense and effort (including with respect to the processing and recordation fee referred to in Section 9.04(b)), upon notice to such Lender and the Administrative Agent, require such Lender to transfer and assign, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all of its interests, rights and obligations under this Agreement to an assignee that shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (x) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority having jurisdiction, (y) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, and (z) the Borrower or such assignee shall have paid to the affected Lender in immediately available funds an amount equal to the sum of the principal of and interest accrued to the date of such payment on the outstanding Loans of such Lender plus all other amounts accrued for the account of such Lender hereunder (including any amounts under Section 2.14 and Section 2.16); provided further that, if prior to any such transfer and assignment the circumstances or event that resulted in such Lender’s claim for compensation under Section 2.14 or notice under Section 2.15 or the amounts paid pursuant to Section 2.20, as the case may be, cease to cause such Lender to suffer increased

costs or reductions in amounts received or receivable or reduction in return on capital, or cease to have the consequences specified in Section 2.15, or cease to result in amounts being payable under Section 2.20, as the case may be (including as a result of any action taken by such Lender pursuant to paragraph (b) below), or if such Lender shall waive its right to claim further compensation under Section 2.14 in respect of such circumstances or event or shall withdraw its notice under Section 2.15 or shall waive its right to further payments under Section 2.20 in respect of such circumstances or event or shall consent to the proposed amendment, waiver, consent or other modification, as the case may be, then such Lender shall not thereafter be required to make any such transfer and assignment hereunder. Each Lender hereby grants to the Administrative Agent an irrevocable power of attorney (which power is coupled with an interest) to execute and deliver, on behalf of such Lender as assignor, any Assignment and Acceptance necessary to effectuate any assignment of such Lender’s interests hereunder in the circumstances contemplated by this Section 2.21(a).

(b) If (i) any Lender shall request compensation under Section 2.14, (ii) any Lender delivers a notice described in Section 2.15 or (iii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority on account of any Lender pursuant to Section 2.20, then such Lender shall use reasonable efforts (which shall not require such Lender to incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any action inconsistent with its internal policies or legal or regulatory restrictions or suffer any disadvantage or burden deemed by it to be significant) (x) to file any certificate or document reasonably requested in writing by the Borrower or (y) to assign its rights and delegate and transfer its obligations hereunder to another of its offices, branches or affiliates, if such filing or assignment would reduce its claims for compensation under Section 2.14 or enable it to withdraw its notice pursuant to Section 2.15 or would reduce amounts payable pursuant to Section 2.20, as the case may be, in the future. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such filing or assignment, delegation and transfer.

then, and in every such event (other than an event with respect to the Borrower described in paragraph (g) or (h) above), and at any time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Required Lenders shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate forthwith the Commitments and (ii) declare the Loans then outstanding to be forthwith due and payable in whole or in part, whereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and any unpaid accrued fees and all other liabilities of the Borrower accrued hereunder and under any other Loan Document, shall become forthwith due and payable, without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in any other Loan Document to the contrary notwithstanding; and in any event with respect to the Borrower described in paragraph (g) or (h) above, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and any unpaid accrued fees and all other liabilities of the Borrower accrued hereunder and under any other Loan Document, shall automatically become due and payable, without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in any other Loan Document to the contrary notwithstanding.

ARTICLE VIII

The Administrative Agent and the Collateral Agent

The Lenders hereby irrevocably appoint the Administrative Agent and the Collateral Agent (for purposes of this Article VIII, the Administrative Agent and the Collateral Agent are referred to collectively as the “Agents”) its agent and authorizes the Agents to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. Without limiting the generality of the foregoing, the Agents are hereby expressly authorized to execute any and all documents (including releases) with respect to the Collateral and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Security Documents.

The bank serving as the Administrative Agent and/or the Collateral Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Neither Agent shall have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) neither Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) neither Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that such Agent is instructed in writing to exercise by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.08), and (c) except as expressly set forth in the Loan Documents, neither Agent shall have any duty to disclose, nor shall it be liable for the failure to disclose, any information relating to the Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent and/or Collateral Agent or any of its Affiliates in any capacity. Neither Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.08) or in the absence of its own gross negligence or wilful misconduct. Neither Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to such Agent by the Borrower or a Lender, and neither Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent.

Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person. Each Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. Each Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Each Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it. Each Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facility provided for herein as well as activities as Agent.

Subject to the appointment and acceptance of a successor Agent as provided below, either Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such

resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After an Agent’s resignation hereunder, the provisions of this Article and Section 9.05 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while acting as Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement or any other Loan Document, any related agreement or any document furnished hereunder or thereunder.

SECTION 9.03. Binding Effect. This Agreement shall become effective as set forth in the Amendment Agreement.

SECTION 9.04. Successors and Assigns. (a) Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Borrower, the Administrative Agent, the Collateral Agent or the Lenders that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns.

(b) Each Lender may assign to one or more assignees all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it), with the prior written consent of the Administrative Agent (not to be unreasonably withheld or delayed); provided, however, that (i) the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $1,000,000 (or, if less, the entire remaining amount of such Lender’s Commitment or Loans), (ii) the parties to each such assignment shall (A) electronically execute and deliver to the Administrative Agent an Assignment and Acceptance via an electronic settlement system acceptable to the Administrative Agent (which initially shall be ClearPar, LLC) or (B) if no such system shall then be specified by the Administrative Agent, manually execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500 and (iii) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and all applicable tax forms. Upon acceptance and recording pursuant to paragraph (e) of this Section 9.04, from and after the effective date specified in each Assignment

and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.16, 2.20 and 9.05, as well as to any amounts accrued for its account and not yet paid).

(c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (ii) except as set forth in (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of the Borrower or any Subsidiary or the performance or observance by the Borrower or any Subsidiary of any of its obligations under this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto; (iii) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (iv) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 3.05 or delivered pursuant to Section 5.04, and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (v) such assignee will independently and without reliance upon the Administrative Agent, the Collateral Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent and the Collateral Agent, respectively, by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(d) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error and the Borrower, the Administrative Agent, the Collateral Agent and the Lenders may treat each person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Collateral Agent and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e) Upon its receipt of, and consent to, a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, an Administrative Questionnaire completed in respect of the assignee (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) above, if applicable, and any applicable tax forms, the Administrative Agent shall (i) accept such Assignment and Acceptance and (ii) record the information contained therein in the Register. No assignment shall be effective unless it has been recorded in the Register as provided in this paragraph (e).

(f) Each Lender may without the consent of the Administrative Agent sell participations to one or more banks or other entities in all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other entities shall be entitled to the benefit of the cost protection provisions contained in Sections 2.14, 2.16 and 2.20 to the same extent as if they were Lenders (but, with respect to any particular participant, to no greater extent than the Lender that sold the participation to such participant) and (iv) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to the Loans owing to it and to approve any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers decreasing any fees payable hereunder the amount of principal of or the rate at which interest is payable on the Loans, extending any scheduled principal payment date or date fixed for the payment of interest on the Loans, increasing or extending the Commitments or releasing any Guarantor (other than in connection with a transaction permitted hereunder) or all or substantially all of the Collateral (except in accordance with Section 9.17)).

(g) Any Lender or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 9.04, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure of information designated by the Borrower as confidential, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of such confidential information on terms no less restrictive than those applicable to the Lenders pursuant to Section 9.16.

(h) Any Lender may at any time assign all or any portion of its rights under this Agreement to secure extensions of credit to such Lender or in support of obligations owed by such Lender; provided that no such assignment shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto.

(i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 9.04, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC.

(j) The Borrower shall not assign or delegate any of its rights or duties hereunder without the prior written consent of the Administrative Agent and each Lender, and any attempted assignment without such consent shall be null and void.

SECTION 9.05. Expenses; Indemnity. (a) The Borrower agrees to pay all reasonable out-of-pocket expenses incurred by the Administrative Agent and the Collateral Agent in connection with the syndication of the credit facilities provided for herein and the preparation and administration of this Agreement and the other Loan Documents or in connection with any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions hereby or thereby contemplated shall be consummated) or incurred by the Administrative Agent, the Collateral Agent or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents or in connection with the Loans made hereunder, including the fees, charges and disbursements of Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Administrative Agent and the Collateral Agent, and, in connection with any such enforcement or protection, the fees, charges and disbursements of any other counsel for the Administrative Agent, the Collateral Agent or any Lender.

(b) The Borrower agrees to indemnify the Administrative Agent, the Collateral Agent, each Lender and each Related Party of any of the foregoing persons (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses,

claims, damages, liabilities and related expenses, including reasonable counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated thereby, the performance by the parties thereto of their respective obligations thereunder or the consummation of the Transactions and the other transactions contemplated thereby (including the syndication of the credit facilities provided for herein), (ii) the use of the proceeds of the Loans, (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto (and regardless of whether such matter is initiated by a third party or by the Borrower, any other Loan Party or any of their respective Affiliates), or (iv) any actual or alleged presence or Release of Hazardous Materials on any property currently or formerly owned or operated by the Borrower or any of the Subsidiaries, or any Environmental Liability related in any way to the Borrower or the Subsidiaries; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Collateral Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent or the Collateral Agent, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Collateral Agent in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon its share of the outstanding Loans and unused Commitments at the time.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and it hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(e) The provisions of this Section 9.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the expiration of the Commitments, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent, the Collateral Agent or any Lender. All amounts due under this Section 9.05 shall be payable on written demand therefor.

SECTION 9.06. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender is hereby authorized at any time and from time to time, except to the extent prohibited by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement and the other Loan Documents

held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or such other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 9.06 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.07. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS OR TO EXTENT THE LAWS OF ANOTHER JURISDICTION MANDATORILY GOVERN ANY LOAN DOCUMENT) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the Administrative Agent, the Collateral Agent or any Lender in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Collateral Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower or any other Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances, except as expressly provided in this Agreement or any other Loan Document.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders; provided, however, that no such agreement shall (i) decrease the principal amount of, or extend the maturity of or any scheduled principal payment date or date for the payment of any interest on any Loan, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Loan, or waive or excuse the payment of (or extend the date for payment of) any prepayment fee, or reduce the amount thereof, without the prior written consent of each Lender affected thereby, (ii) increase or extend the Commitment of any Lender without the prior written consent of such Lender, (iii) amend or modify the pro rata requirements of Section 2.17, the provisions of Section 9.04(j) or the provisions of this Section, or release any Guarantor (other than in connection with a transaction permitted hereunder) or all or substantially all of the Collateral (except in accordance with Section 9.17), without the prior written consent of each Lender, (iv) modify the protections afforded to an SPC pursuant to the provisions of Section 9.04(i) without the written consent of such SPC, or (v) reduce the percentage contained in the definition of the term “Required Lenders” without the prior written consent of each Lender (it being understood that with the consent of the Required Lenders, additional extensions of credit pursuant to this Agreement may be included in the determination of the Required Lenders on substantially the same basis as the Commitments on the date hereof); provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Collateral Agent hereunder or under any other Loan Document without the prior written consent of the Administrative Agent or the Collateral Agent.

SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 9.09 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.10. Entire Agreement. This Agreement, the Fee Letter and the other Loan Documents constitute the entire contract between the parties relative to the subject matter hereof. Any other previous agreement among the parties with respect to the subject matter hereof is superseded by this Agreement, the Fee Letter and the other Loan Documents. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any person (other than the parties hereto and thereto, their respective successors and assigns permitted hereunder and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Collateral Agent and the Lenders) any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents.

SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

SECTION 9.12. Severability. In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 9.13. [Intentionally Omitted].

SECTION 9.14. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the Collateral Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or its properties in the courts of any jurisdiction.

(b) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any New York State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law; provided that notice of the use of any such alternative means of service shall be provided to each affected party in the manner provided in Section 9.01.

SECTION 9.16. Confidentiality. Each of the Administrative Agent, the Collateral Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ officers, directors, 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 quasi-regulatory authority (such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) in connection with the exercise of any remedies hereunder or under the other Loan Documents or any suit, action or proceeding

For the purposes of this Section, “Information” shall mean all information received from the Borrower and related to the Borrower or its business, other than any such information that was available to the Administrative Agent, the Collateral Agent or any Lender on a nonconfidential basis prior to its disclosure by the Borrower; provided that, in the case of Information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any person required to maintain the confidentiality of Information as provided in this Section 9.16 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 its own confidential information.

SECTION 9.17. Release of Guarantees and Collateral in Certain Circumstances. If the Borrower reasonably determines that the Guarantee given by any Subsidiary Guarantor or the Collateral granted by any Subsidiary that is a Collateral Loan Party (other than, in each case, any Subsidiary Guarantor or Collateral Loan Party that is a Domestic Subsidiary), in each case under the Guarantee and Collateral Agreement or other applicable Security Document, will result in the Borrower being deemed to have received a dividend for U.S. federal income tax purposes, then, upon notice thereof by the Borrower to the Administrative Agent and provided that (a) no Default or Event of Default has occurred and is continuing and (b) after giving effect to the proposed release the Borrower would be in pro forma compliance with the covenant set forth in Section 5.09(c) (substituting for purposes of making such determination the phrase “not less than 75% of PV-10 Value” for the phrase “not less than 95% of PV-10 Value” set forth therein), such Guarantee and such Collateral shall be released, and the pledge of the Equity Interests of such Subsidiary Guarantor under the Guarantee and Collateral Agreement or other applicable Security Document shall be reduced to 100% of the non-voting Equity Interests (if any) and 65% of the voting Equity Interests of such Subsidiary Guarantor. In connection with any such release, the Collateral Agent shall execute and deliver to the Borrower, at the Borrower’s expense, all documents the Borrower shall reasonably request to evidence such release. Any execution and delivery of documents pursuant to this Section 9.17 shall be without recourse to or warranty by the Collateral Agent.

SECTION 9.18. USA Patriot Act Notice. Each Lender and the Administrative Agent (for 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 Borrower in accordance with the USA Patriot Act.

SECTION 9.19. Parallel Debt. (a) Notwithstanding anything to the contrary contained in this Agreement and the other Loan Documents and solely for the purpose of ensuring and preserving the validity and effect of the security rights granted and to be granted under or

pursuant to the Security Documents governed by the laws of The Netherlands (the “Dutch Security Agreements”), each of the Lenders and the other parties hereto hereby acknowledges and consents to (i) each Loan Party that is party to the Dutch Security Agreements undertaking herein to pay to the Collateral Agent, in its individual capacity and not as agent, representative or trustee, as a separate independent obligation to the Collateral Agent, the amount of its Dutch Parallel Debt (which each such Loan Party hereby so undertakes to do), and (ii) the security rights contemplated by the Dutch Security Agreements being granted in favor of the Collateral Agent in its individual capacity as security for its claims under the Dutch Parallel Debt.

(b) Each Loan Party acknowledges and agrees that it may not pay its Dutch Parallel Debt other than at the instruction of, and in the manner instructed by, the Collateral Agent; provided, however, that no Loan Party shall be obligated to pay any amount of its Dutch Parallel Debt unless and until a corresponding amount of its Underlying Debt Obligations shall have become due and payable.

(c) To the extent any amount is paid to and received by the Collateral Agent in payment of the Dutch Parallel Debt and the Collateral Agent has turned over any amounts received by it in respect to the Dutch Parallel Debt to the Lenders as their interests appeared with respect to the Underlying Debt Obligations, the total amount due and payable in respect of the Underlying Debt Obligations shall be decreased as if such amount were received by the Lenders or any of them in payment of the corresponding Underlying Debt Obligations.

SECTION 9.20. Effect of Restatement. This Agreement shall, except as otherwise expressly set forth herein, supersede the Existing Credit Agreement from and after the Restatement Date with respect to the Loans outstanding under the Existing Credit Agreement as of the Restatement Date. The parties hereto acknowledge and agree, however, that except to the extent contemplated hereby with respect to the borrowing of the New Term Loans and prepayment of certain of the Existing Term Loans in accordance with the Amendment Agreement, (a) this Agreement and all other Loan Documents executed and delivered herewith do not constitute a novation, payment and reborrowing or termination of the Obligations under the Existing Credit Agreement and the other Loan Documents as in effect prior to the Restatement Date, (b) such Obligations are in all respects continuing with only the terms being modified as provided in this Agreement and the other Loan Documents, (c) the liens and security interests in favor of the Collateral Agent for the benefit of the Secured Parties securing payment of such Obligations are in all respects continuing and in full force and effect with respect to all Obligations and (d) all references in the other Loan Documents to the Credit Agreement shall be deemed to refer without further amendment to this Agreement.
