Credit Agreement dated December 14, 2004

CREDIT AGREEMENT, dated as of December 14, 2004, among TEXAS GENCO HOLDINGS, INC., a Texas corporation (the “Borrower”), TEXAS GENCO GP, LLC, a Texas limited liability company (“Genco GP”), TEXAS GENCO LP, LLC, a Texas limited liability company (“Genco LP”), TEXAS GENCO SERVICES, LP, a Texas limited partnership (“Genco Services”), TEXAS GENCO, LP, a Texas limited partnership (“Genco”), TEXAS GENCO II, LP, a Texas limited partnership (“Genco II”), TEXAS GENCO II GP, LLC, a Texas limited liability company (“Genco II LLC”), the Lenders from time to time party hereto and GOLDMAN SACHS CREDIT PARTNERS L.P., as Administrative Agent. Unless otherwise defined herein, all capitalized terms used herein and defined in Section 9 are used herein as so defined.

WHEREAS, subject to the terms and conditions set forth herein, the Lenders are willing to make available to the Borrower the credit facility provided herein;

1.01 The Commitment. Subject to and upon the terms and conditions set forth herein, each Lender severally agrees to make a term loan (each, a “Loan” and, collectively, the “Loans”) to the Borrower during the period from and including the Effective Date to but excluding the Maturity Date, which Loans (i) shall be denominated in Dollars, (ii) shall be borrowed in a single borrowing (the “Borrowing”), (iii) once repaid shall not be reborrowed, (iv) shall not exceed for any Lender such Lender’s Commitment and (v) shall not exceed for all Lenders the Total Commitment.

1.02 Minimum Amount of Borrowing. The aggregate principal amount of the Borrowing shall be not less than the Minimum Borrowing Amount.

1.03 Notice of Borrowing. (a) A Responsible Officer of the Borrower shall give the Administrative Agent, at the Notice Office, at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) of the Borrower’s desire to make the Borrowing (provided that such notice shall not be effective until the Borrower provides written or oral confirmation thereof on the day of the Borrowing). Such written notice or written confirmation of telephonic notice (the “Notice of Borrowing”), except as otherwise expressly provided in Section 1.08, shall be irrevocable and shall be given by a Responsible Officer of the Borrower in the form of Exhibit A, appropriately completed to specify the aggregate principal amount of the Loans to be made pursuant to the Borrowing and the date of the Borrowing (which shall be a Business Day). The Administrative Agent shall promptly give each Lender notice of the proposed Borrowing, of such Lender’s proportionate share thereof and of the other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing.

(b) Without in any way limiting the obligation of the Borrower to confirm in writing any telephonic notice of the Borrowing or any prepayment of Loans, the Administrative Agent may act without liability upon the basis of telephonic notice of the Borrowing or such

prepayment, believed by the Administrative Agent in good faith to be from a Responsible Officer of the Borrower prior to receipt of written confirmation. In each such case, the Borrower hereby waives the right to dispute the Administrative Agent’s record of the terms of such telephonic notice of the Borrowing or such prepayment.

1.04 Disbursement of Funds. Except as otherwise specifically provided in the immediately succeeding sentence, no later than 9:30 a.m. (New York City time) on the date specified in the Notice of Borrowing, each Lender will make available to the Administrative Agent such Lender’s Percentage of the Borrowing. All such amounts shall be made available in Dollars and in immediately available funds at the Payment Office, and the Administrative Agent will make available to the Borrower at the Payment Office the aggregate of the amounts so made available by the Lenders. Unless the Administrative Agent shall have been notified by any Lender prior to the date of the Borrowing that such Lender does not intend to make available to the Administrative Agent such Lender’s portion of the Borrowing, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower to immediately pay such corresponding amount to the Administrative Agent. The Administrative Agent shall also be entitled to recover on demand from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower until the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if recovered from such Lender, the overnight Federal Funds Rate for the first three days and at the interest rate otherwise applicable to such Loans for each day thereafter and (ii) if recovered from the Borrower, the rate of interest applicable to the Borrowing, as determined pursuant to Section 1.07. Nothing in this Section 1.04 shall be deemed to relieve any Lender from its obligation to make Loans hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any failure by such Lender to make Loans hereunder.

(a) Subject to the provisions of Section 1.05(d), the Borrower’s obligation to pay the principal of and interest on the Loans made by each Lender shall be evidenced in the Register maintained by the Administrative Agent pursuant to Section 11.16 and shall, if requested by such Lender, also be evidenced by a promissory note duly executed and delivered by the Borrower substantially in the form of Exhibit B, with blanks appropriately completed in conformity herewith (each a “Note” and, collectively, the “Notes”).

(b) Each Note issued to a Lender shall (i) be executed by the Borrower, (ii) be payable to such Lender or its registered assigns and be dated the Effective Date (or if issued thereafter, the date of issuance), (iii) be in a stated principal amount equal to the Commitment of such Lender (or, if issued after the termination thereof, be in a stated principal amount equal to the outstanding Loans of such Lender at such time) and be payable in the principal amount of the

Loans evidenced thereby, (iv) mature on the Maturity Date, (v) bear interest as provided in Section 1.07, (vi) be subject to voluntary prepayment as provided in Section 3.01 and (vii) be entitled to the benefits of this Agreement and the other Credit Documents.

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

(d) Notwithstanding anything to the contrary contained above or elsewhere in this Agreement, Notes shall only be delivered to Lenders which at any time (or from time to time) specifically request the delivery of such Notes. No failure of any Lender to request or obtain, produce or maintain a Note evidencing its Loans to the Borrower shall affect or in any manner impair the obligations of the Borrower to pay the Loans (and all related Obligations) which would otherwise be evidenced thereby in accordance with the requirements of this Agreement, and shall not in any way affect the guaranties therefor provided pursuant to the Guaranty or any Credit Document. Any Lender which does not have a Note evidencing its outstanding Loans shall in no event be required to make the notations otherwise described in preceding clause (c) of this Section 1.05. At any time when any Lender requests the delivery of a Note to evidence any of its Loans, the Borrower shall promptly execute and deliver to the respective Lender the requested Note or Notes in the appropriate amount or amounts to evidence such Loans.

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

(a) The Borrower agrees to pay interest in respect of the unpaid principal amount of each Loan from the date the proceeds thereof are made available to the Borrower until the maturity (whether by acceleration or otherwise) of such Loan at a rate per annum equal to the sum of the Eurodollar Rate plus 1.00%.

(b) Overdue principal and, to the extent permitted by law, overdue interest and any other amounts payable hereunder or under any other Credit Document shall in each case bear interest at a rate per annum equal to the rate which is 2% in excess of the rate then borne by such principal, interest or other amounts. Interest which accrues under this Section 1.07(b) shall be payable by the Borrower on demand.

(c) Accrued (and theretofore unpaid) interest shall be payable at maturity (whether by acceleration or otherwise) and, after such maturity, on demand.

1.08 Increased Costs, Illegality, etc. (a) In the event that any Lender shall have determined (which determination shall, absent manifest error, be final and conclusive and

binding upon all parties hereto but, with respect to clause (i) below, may be made only by the Administrative Agent):

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

(ii) that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to any Loan because of any change since the Effective Date in any applicable law or governmental rule, regulation, order, guideline or request (whether or not having the force of law) or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, order, guideline or request, such as, for example, but not limited to: (A) a change in the basis of taxation of payment to any Lender of the principal of or interest on the Loans or the Notes or any other amounts payable hereunder (except for changes in the rate of tax on, or determined by reference to, the net income or net profits of such Lender pursuant to the laws of the jurisdiction in which it is organized or in which its principal office or applicable lending office is located or any subdivision thereof or therein), or (B) a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of the Eurodollar Rate; or

(iii) that the making of any Loan has been made (x) unlawful by any law or governmental rule, regulation or order, (y) impossible by compliance by any Lender in good faith with any governmental request (whether or not having force of law) or (z) impracticable as a result of a contingency occurring after the Effective Date which materially and adversely affects the interbank Eurodollar market;

then, and in any such event, such Lender (or the Administrative Agent, in the case of clause (i) above) shall promptly give notice (by telephone confirmed in writing) to the Borrower and, except in the case of clause (i) above, to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and if the Notice of Borrowing shall be given by the Borrower with respect to Loans which have not yet been incurred it shall be deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the Borrower agrees to pay to such Lender, upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its sole discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts received or receivable hereunder (a written notice as to the additional amounts owed to such Lender, showing the basis for the calculation thereof, submitted to the Borrower by such Lender in good faith shall, absent manifest error, be final and conclusive and binding on all the parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 1.08(b) as promptly as possible and, in any event, within the time period required by law.

(b) At any time that any Loan is affected by the circumstances described in Section 1.08(a)(ii) or (iii), the Borrower may (and in the case of a Loan affected by the circumstances described in Section 1.08(a)(iii) shall) either (x) if the affected Loan is then being made initially, cancel the Borrowing by giving the Administrative Agent telephonic notice (confirmed in writing) on the same date that the Borrower was notified by the affected Lender or the Administrative Agent pursuant to Section 1.08(a)(ii) or (iii) or (y) if the affected Loan is then outstanding, prepay such Loan on the same date that the Borrower was notified by the affected Lender or the Administrative Agent pursuant to Section 1.08(a)(ii) or (iii).

(c) If at any time after the Effective Date any Lender determines that the introduction of or any change in any applicable law or governmental rule, regulation, order, guideline, directive or request (whether or not having the force of law) concerning capital adequacy, or any change in interpretation or administration thereof by any governmental authority, central bank or comparable agency, will have the effect of increasing the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender based on the existence of such Lender’s Commitment hereunder or its obligations hereunder, then the Borrower agrees to pay to such Lender, upon its written demand therefor, such additional amounts as shall be required to compensate such Lender or such other corporation for the increased cost to such Lender or such other corporation or the reduction in the rate of return to such Lender or such other corporation as a result of such increase of capital. In determining such additional amounts, each Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable, provided that such Lender’s determination of compensation owing under this Section 1.08(c) shall, absent manifest error, be final and conclusive and binding on all the parties hereto. Each Lender, upon determining that any additional amounts will be payable pursuant to this Section 1.08(c), will give written notice thereof to the Borrower, which notice shall show the basis for calculation of such additional amounts.

(d) The provisions contained in this Section 1.08 shall survive the termination of this Agreement and the payment of all amounts payable hereunder; provided, however, that in no event shall the Borrower be obligated to reimburse or compensate any Lender for amounts contemplated by this Section 1.08 for any period prior to the date that is 90 days prior to the date upon which such Lender requests in writing such reimbursement or compensation from the Borrower. This Section 1.08(d) shall have no applicability to any other Section of this Agreement.

1.09 Compensation. The Borrower agrees to compensate each Lender, upon its written request (which request shall set forth the basis for requesting such compensation), for all reasonable losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its Loans but excluding any loss of anticipated profit) which such Lender may sustain: (i) if for any reason (other than a default by such Lender) the Borrowing does not occur on a date specified therefor in the Notice of Borrowing (whether or not withdrawn by the Borrower or deemed withdrawn pursuant to Section 1.08(a)); (ii) if any prepayment of any of its Loans is not made on any date specified in a notice of prepayment given by the Borrower; or (iii) as a consequence of (x) any other default by the Borrower to repay its Loans when required by the terms of this Agreement or any Note held by such Lender or (y) any

election made pursuant to Section 1.08(b). The provisions contained in this Section 1.09 shall survive the termination of this Agreement and the payment of all amounts payable hereunder; provided, however, that in no event shall the Borrower be obligated to reimburse or compensate any Lender for amounts contemplated by this Section 1.09 for any period prior to the date that is 90 days prior to the date upon which such Lender requests in writing such reimbursement or compensation from the Borrower, provided, further, that this sentence shall have no applicability to any other Section of this Agreement.

1.10 Change of Lending Office. Each Lender agrees that upon the occurrence of any event giving rise to the operation of Section 1.08(a)(ii) or (iii), Section 1.08(c) or Section 3.04 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event, provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of such Section. Nothing in this Section 1.10 shall affect or postpone any of the obligations of the Borrower or the rights of any Lender provided in Sections 1.08 and 3.04.

1.11 Replacement of Lenders. (a) If any Lender becomes a Defaulting Lender or otherwise defaults in its obligations to make Loans or (b) upon the occurrence of any event giving rise to the operation of Section 1.08(a)(ii) or (iii), Section 1.08(c) or Section 3.04 with respect to any Lender which results in such Lender charging to the Borrower increased costs in excess of those being generally charged by the other Lenders, then in each case the Borrower shall have the right, if no Default or Event of Default will exist immediately after giving effect to the respective replacement, to replace such Lender (the “Replaced Lender”) with one or more other Eligible Transferee or Transferees, none of whom shall constitute a Defaulting Lender at the time of such replacement (collectively, the “Replacement Lender”) reasonably acceptable to the Administrative Agent, provided that (i) at the time of any replacement pursuant to this Section 1.11, the Replacement Lender shall enter into one or more Assignment and Assumption Agreements pursuant to Section 11.04(b) (and with all fees payable pursuant to said Section 11.04(b) to be paid by the Replacement Lender) pursuant to which the Replacement Lender shall acquire the Commitment and all outstanding Loans of the Replaced Lender and, in connection therewith, shall pay to the Replaced Lender in respect thereof an amount equal to the principal of, and all accrued interest on, all outstanding Loans of the Replaced Lender, and (ii) all obligations of the Borrower owing to the Replaced Lender (other than those specifically described in clause (i) above in respect of which the assignment purchase price has been, or is concurrently being, paid) shall be paid in full to such Replaced Lender concurrently with such replacement. Upon the execution of the respective Assignment and Assumption Agreements, the payment of amounts referred to in clauses (i) and (ii) above and, if so requested by the Replacement Lender, delivery to the Replacement Lender of the appropriate Notes executed by the Borrower, the Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder, except with respect to indemnification provisions under this Agreement (including, without limitation, Sections 1.08, 1.09, 3.04, 11.01 and 11.06), which shall survive as to such Replaced Lender.

The Total Commitment (and the Commitment of each Lender) shall terminate in its entirety on the earlier of (a) at 5:00 p.m. (New York time) on September 30, 2005 and (b) at 5:00 p.m. (New York time) on the Business Day immediately preceding the Maturity Date.

3.01 Voluntary Prepayments. The Borrower shall have the right to prepay the Loans, without premium or penalty, in whole but not in part, so long as a Responsible Officer of the Borrower provides written notice (or telephonic notice promptly confirmed in writing) thereof to the Administrative Agent at the Notice Office prior to 1:30 p.m. (New York City time) on the date of prepayment.

3.02 Repayment on Maturity Date. The Borrower shall repay all outstanding Loans in full on the Maturity Date.

3.03 Method and Place of Payment. Except as otherwise specifically provided herein, all payments under this Agreement or any Note shall be made to the Administrative Agent for the account of the Lender or Lenders entitled thereto not later than 2:00 p.m. (New York City time) on the date when due and shall be made in Dollars in immediately available funds at the Payment Office. Any payments received by the Administrative Agent after such time shall be deemed to have been received on the next Business Day. Whenever any payment to be made hereunder or under any Note shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable at the applicable rate during such extension.

3.04 Net Payments. (a) All payments made by the Borrower hereunder or under any Note will be made without setoff, counterclaim or other defense. Except as provided in Section 3.04(b), all such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, except as provided in the second succeeding sentence, any tax imposed on or measured by the net income or net profits of a Lender pursuant to the laws of the jurisdiction in which it is organized or the jurisdiction in which the principal office or applicable lending office of such Lender is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower agrees to pay the full amount of such Taxes, and such additional amounts as may be necessary so that every payment of all amounts due under this Agreement or under any Note, after withholding or deduction for or on account of any Taxes, will not be less than the amount provided for herein or in such Note. If any amounts are payable in respect of Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each Lender, upon the written request of such Lender, for taxes imposed on or measured by the net income or net profits of such Lender pursuant to the laws of the jurisdiction in which such Lender is organized

or in which the principal office or applicable lending office of such Lender is located or under the laws of any political subdivision or taxing authority of any such jurisdiction in which such Lender is organized or in which the principal office or applicable lending office of such Lender is located and for any withholding or similar taxes as such Lender shall determine are payable by, or withheld from, such Lender but only in respect of such amounts so paid to or on behalf of such Lender pursuant to the preceding sentence and in respect of any amounts paid to or on behalf of such Lender pursuant to this sentence. The Borrower will furnish to the Administrative Agent within 45 days after the date the payment or other documentary proof providing evidence of such payment that is satisfactory to the Administrative Agent of any Taxes is due pursuant to applicable law certified copies of tax receipts evidencing such payment by the Borrower. The Borrower agrees to indemnify and hold harmless each Lender, and reimburse such Lender upon its written request, for the amount of any Taxes so levied or imposed and paid by such Lender.

(b) Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) agrees to deliver to the Borrower and the Administrative Agent on or prior to the date of this Agreement, or in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 1.11 or 11.04 (unless the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (i) two accurate and complete original signed copies of Internal Revenue Service Form W-8ECI or Form W8BEN (with respect to a complete exemption under an income tax treaty) (or successor forms) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note, or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code and cannot deliver either Internal Revenue Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption under an income tax treaty) pursuant to clause (i) above, (x) a certificate substantially in the form of Exhibit C (any such certificate, a “Section 3.04(b)(ii)Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN (with respect to the portfolio interest exemption) (or successor form) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Note. In addition, each Lender agrees that from time to time after the date of this Agreement, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to the Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form W-8ECI, Form W-8BEN (with respect to the benefits of any income tax treaty), or Form W-8BEN (with respect to the portfolio interest exemption) and a Section 3.04(b)(ii) Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement and any Note, or it shall immediately notify the Borrower and the Administrative Agent of its inability to deliver any such Form or Certificate, in which case such Lender shall not be required to deliver any such Form or Certificate pursuant to this Section 3.04(b). Notwithstanding anything to the contrary contained in Section 3.04(a), but subject to Section 11.04(b) and the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the

account of any Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for U.S. Federal income tax purposes to the extent that such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 3.04(a) hereof to gross-up payments to be made to a Lender, or to indemnify, hold harmless or reimburse such Lender, in respect of income or similar taxes imposed by the United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the Borrower pursuant to this Section 3.04(b) or (II) in the case of a payment, other than interest, to a Lender described in clause (ii) above, to the extent that such forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this Section 3.04 and except as set forth in Section 11.04(b), the Borrower agrees to pay additional amounts and to indemnify each Lender in the manner set forth in Section 3.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts deducted or withheld by it as described in the immediately preceding sentence as a result of any changes after the Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of income or similar Taxes (except for changes in the rate of tax on, or determined by reference to, the net income or net profits of such Lender pursuant to the laws of the jurisdiction in which it is organized or in which its principal office or applicable lending office is located or any subdivision thereof or therein provided that this parenthetical exception shall not apply for purposes of applying the fourth sentence of Section 3.04(a)).

10.01 Appointment. The Lenders hereby designate GSCP as Administrative Agent and Lead Arranger to act as specified herein and in the other Credit Documents. Each Lender hereby irrevocably authorizes, and each holder of any Note by the acceptance of such Note shall be deemed irrevocably to authorize, each Agent to take such action on its behalf under the provisions of this Agreement, the other Credit Documents and any other instruments and agreements referred to herein or therein and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of each Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto. Each Agent may

perform any of its duties hereunder by or through their respective officers, directors, agents, employees or affiliates.

10.02 Nature of Duties. The Agents shall not have any duties or responsibilities except those expressly set forth in this Agreement and the other Credit Documents. No Agent or any of its respective officers, directors, agents, employees or affiliates shall be liable for any action taken or omitted by it hereunder or under any other Credit Document or in connection herewith or therewith, unless caused by their gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision). The duties of the Agents shall be mechanical and administrative in nature; no Agent shall have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Lender or the holder of any Note; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon any Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

10.03 Lack of Reliance on the Agents. Independently and without reliance upon any Agent, each Lender and the holder of each Note, to the extent it deems appropriate, has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of the Borrower and its Subsidiaries in connection with the making and the continuance of the Loans and the taking or not taking of any action in connection herewith and (ii) its own appraisal of the creditworthiness of the Borrower and its Subsidiaries and, except as expressly provided in this Agreement, no Agent shall have any duty or responsibility, either initially or on a continuing basis, to provide any Lender or the holder of any Note with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any time or times thereafter. No Agent nor any of its affiliates or any of its officers, directors, agents or employees shall be responsible to any Lender or the holder of any Note for any recitals, statements, information, representations or warranties herein or in any document, certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of this Agreement or any other Credit Document or the financial condition of the Borrower and its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any other Credit Document, or the financial condition of the Borrower and its Subsidiaries or the existence or possible existence of any Default or Event of Default.

10.04 Certain Rights of the Agents. If any Agent shall request instructions from the Required Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Credit Document, such Agent shall be entitled to refrain from such act or taking such action unless and until such Agent shall have received instructions from the Required Lenders; and such Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender or any holder of any Note shall have any right of action whatsoever against any Agent as a result of such Agent acting or refraining from acting hereunder or under any other Credit Document in accordance with the instructions of the Required Lenders.

10.05 Reliance. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype, facsimile or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by any Person that such Agent believed to be the proper Person, and, with respect to all legal matters pertaining to this Agreement and any other Credit Document and its duties hereunder and thereunder, upon advice of counsel selected by such Agent (which may be counsel for the Credit Parties).

10.06 Indemnification. To the extent that any Agent is not reimbursed and indemnified by the Borrower, each Lender will reimburse and indemnify such Agent, in proportion to its “percentage” as used in determining the Required Lenders (determined as if there were no Defaulting Lenders) for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by such Agent in performing its duties hereunder or under any other Credit Document, in any way relating to or arising out of this Agreement or any other Credit Document; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision).

10.07 The Agents in Their Individual Capacity. With respect to its obligation to make Loans under this Agreement, each Agent shall have the rights and powers specified herein for a “Lender” and may exercise the same rights and powers as though it were not performing the duties specified herein; and the term “Lenders,” “Required Lenders,” “holders of Notes” or any similar terms shall, unless the context clearly otherwise indicates, include each Agent in its individual capacity. Each Agent may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with any Credit Party or any Affiliate of any Credit Party as if it were not performing the duties specified herein, and may accept fees and other consideration from the Borrower, or any other Credit Party for services in connection with this Agreement and otherwise without having to account for the same to the Lenders.

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

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

(b) Upon any such notice of resignation, the Required Lenders shall, with the consent of the Borrower (which consent shall not be unreasonably withheld or delayed and shall not be required at any time when an Event of Default exists), appoint a successor Administrative Agent hereunder or thereunder who shall be a commercial bank or trust company.

(c) If a successor Administrative Agent shall not have been so appointed within such 15 Business Day period, the Administrative Agent, with the consent of the Borrower (which consent shall not be unreasonably withheld or delayed and shall not be required at any time when an Event of Default exists), shall then appoint a commercial bank or trust company as successor Administrative Agent who shall serve as Administrative Agent hereunder or thereunder until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above.

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

(e) Upon a resignation of any Agent pursuant to this Section 10.09, such Agent shall remain indemnified to the extent provided in this Agreement and the other Credit Documents and the provisions of this Section 10 shall continue in effect for the benefit of such Agent for all of its actions and inactions while serving as an Agent.

11.01 Payment of Expenses, etc. The Borrower shall: (i) whether or not the transactions herein contemplated are consummated, pay all reasonable out-of-pocket costs and expenses of (x) the Administrative Agent in connection with the preparation, execution and delivery of this Agreement and the other Credit Documents and the documents and instruments referred to herein and therein and any amendment, waiver or consent relating hereto or thereto, it being understood that for purposes of this clause (x), the Administrative Agent shall use no more than one transaction counsel and such local counsel as reasonably necessary, (y) each Agent in connection with its syndication efforts with respect to this Agreement and (z) the Administrative Agent and, following and during the continuation of an Event of Default, each of the Lenders in connection with the enforcement of this Agreement and the other Credit Documents and the documents and instruments referred to herein and therein (including, without limitation, the reasonable fees and disbursements of counsel and consultants for the Administrative Agent and, following and during the continuation of an Event of Default, for each of the Lenders) in each case promptly following receipt of a reasonably detailed invoice therefor; (ii) without duplication of any other payments paid or payable pursuant to any

other provision of this Agreement or any other Credit Document, pay and hold each of the Lenders harmless from and against any and all present and future stamp, excise and other similar taxes with respect to the foregoing matters and hold each of the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to such Lender) to pay such taxes; and (iii) without duplication of any other payments paid or payable pursuant to any other provision of this Agreement or any other Credit Document, indemnify each Agent and each Lender, and each of their respective officers, directors, employees, representatives, affiliates and agents from and hold each of them harmless against any and all liabilities, obligations (including removal or remedial actions), losses, damages, penalties, claims, actions, judgments, suits, costs, expenses and disbursements (including reasonable attorneys’ and consultants’ fees and disbursements) incurred by, imposed on or assessed against any of them as a result of, or arising out of, or in any way related to, or by reason of, (a) any investigation, litigation or other proceeding (whether or not any Agent or any Lender is a party thereto) related to the entering into and/or performance of this Agreement or any other Credit Document or the use of the proceeds of any Loans hereunder or the consummation of any transactions contemplated herein or in any other Credit Document or the exercise of any of their rights or remedies provided herein or in the other Credit Documents, or (b) the actual or alleged presence of Hazardous Materials in the air, surface water or groundwater or on the surface or subsurface of any Real Property owned or at any time operated by the Borrower or any of its Subsidiaries, the generation, storage, transportation, handling or disposal of Hazardous Materials at any location, whether or not owned or operated by the Borrower or any of its Subsidiaries, the non-compliance of any Real Property with foreign, federal, state and local laws, regulations, and ordinances (including applicable permits thereunder) applicable to any Real Property, or any Environmental Action asserted against the Borrower, any of its Subsidiaries, or any Real Property owned or at any time operated by the Borrower or any of its Subsidiaries, including, in each case, without limitation, the reasonable fees and disbursements of counsel and other consultants incurred in connection with any such investigation, litigation or other proceeding (but excluding any losses, liabilities, claims, damages or expenses to the extent incurred by reason of the gross negligence or willful misconduct of the Person to be indemnified (as determined by a court of competent jurisdiction in a final and non-appealable decision)). To the extent that the undertaking to indemnify, pay or hold harmless any Agent or any Lender set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, the Borrower shall make the maximum contribution to the payment and satisfaction of each of the indemnified liabilities which is permissible under applicable law.

11.02 Right of Setoff. In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default, each Lender is hereby authorized at any time or from time to time, without presentment, demand, protest or other notice of any kind to the Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other Indebtedness at any time held or owing by such Lender (including, without limitation, by branches and agencies of such Lender wherever located) to or for the credit or the account of any Credit Party against and on account of the Obligations and liabilities of all Credit Parties to such Lender under this Agreement or under any of the other Credit Documents, including, without limitation, all interests in Obligations purchased by such Lender pursuant to Section 11.06(b), and all other claims of any nature or description arising out of or connected with this Agreement or any other Credit Document, irrespective of whether or not such Lender shall have made any demand hereunder and although said Obligations, liabilities or claims, or any of them, shall be contingent or unmatured.

11.03 Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including telegraphic, telex, telecopier or cable communication) and mailed, telegraphed, telexed, telecopied, cabled or delivered: if to the Borrower, at the Borrower’s address specified below its signature below; if to any other Credit Party, at such Credit Party’s address set forth below its signature below; if to any Lender, at its address specified on Schedule II below; and if to the Administrative Agent, at the Notice Office; or, as to any Credit Party or the Administrative Agent, at such other address as shall be designated by such party in a written notice to the other parties hereto and, as to each Lender, at such other address as shall be designated by such Lender in a written notice to the Borrower and the Administrative Agent. All such notices and communications shall, when mailed, telegraphed, telexed, telecopied, or cabled or sent by overnight courier, be effective when deposited in the mails, delivered to the telegraph company, cable company or overnight courier, as the case may be, or sent by telex or telecopier, except that notices and communications to the Administrative Agent shall not be effective until received by the Administrative Agent.

11.04 Benefit of Agreement. (a) This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, that the Borrower may not assign or transfer any of its rights, obligations or interest hereunder or under any other Credit Document without the prior written consent of all of the Lenders and the Administrative Agent and, provided further, that although any Lender may transfer, assign or grant participations in its rights hereunder, such Lender shall remain a “Lender” for all purposes hereunder (and may not transfer or assign all or any portion of its Commitment hereunder except as provided in Section 11.04(b)) and the transferee, assignee or participant, as the case may be, shall not constitute a “Lender” hereunder and, provided further, that no Lender shall transfer or grant any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) extend the final scheduled maturity of any Loan or Note beyond the Maturity Date, or reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of applicability of any post-default increase in interest rates) or reduce the principal amount thereof, or increase the amount of the participant’s participation over the amount thereof then in effect (it being understood that waivers or modifications of conditions precedent, covenants, Defaults or Events of Default shall not constitute a change in the terms of such participation, and that an increase in any Commitment shall be permitted without the consent of any participant if the participant’s participation is not increased as a result thereof) or (ii) consent to the assignment or transfer by the Borrower of any of their rights and obligations under this Agreement. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the other Credit Documents (the participant’s rights against such Lender in respect of such participation to be those set forth in the agreement executed by such Lender in favor of the participant relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation.

(b) Notwithstanding the foregoing, any Lender (or any Lender together with one or more other Lenders) may (x) assign all or a portion of its Commitment and related outstanding Obligations hereunder (or, if the Commitments have terminated, its outstanding Obligations) to (i) its parent company and/or any affiliate of such Lender which is at least 50%

owned by such Lender or its parent company or to one or more other Lenders or (ii) in the case of any Lender that is a fund that invests in bank loans, any other fund that invests in bank loans and is managed by the same investment advisor of such Lender or by an Affiliate of such investment advisor or (y) assign all, or if less than all, a portion equal to at least $1,000,000 in the aggregate for the assigning Lender or assigning Lenders, of such Commitments and related outstanding Obligations hereunder (or, if the Commitments have terminated, its outstanding Obligations) to one or more Eligible Transferees, each of which assignees shall become a party to this Agreement as a Lender by execution of an Assignment and Assumption Agreement, provided that (i) at such time Schedule I shall be deemed modified to reflect the Commitment of such new Lender and of the existing Lenders, (ii) at the request of the assignee Lender, and upon surrender of the relevant Notes or the provision of a customary lost note indemnification agreement from the assignor or assignee Lender, as the case may be, new Notes will be issued, at the Borrowers’ expense, to such new Lender and to the assigning Lender, such new Notes to be in conformity with the requirements of Section 1.05 (with appropriate modifications) to the extent needed to reflect the revised Commitments, (iii) the consent of the Administrative Agent and, at any time when no Default or Event of Default is in existence, the Borrower shall be required in connection with any such assignment pursuant to clause (y) above (each of which consents shall not to be unreasonably withheld or delayed), and (iv) the Administrative Agent shall receive at the time of each such assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500 and, provided further, that such transfer or assignment will not be effective until recorded by the Administrative Agent on the Register pursuant to Section 11.16 hereof. To the extent of any assignment pursuant to this Section 11.04(b), the assigning Lender shall be relieved of its obligations hereunder with respect to its assigned Commitments. At the time of each assignment pursuant to this Section 11.04(b) to a Person which is not already a Lender hereunder and which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for Federal income tax purposes, the respective assignee Lender shall provide to the Borrower and the Administrative Agent the appropriate Internal Revenue Service Forms (and, if applicable a Section 3.04(b)(ii) Certificate) described in Section 3.04(b). To the extent that an assignment of all or any portion of a Lender’s Commitments and related outstanding Obligations pursuant to Section 1.11 or this Section 11.04(b) would, at the time of such assignment, result in increased costs under Section 1.08, 1.09 or 3.04 greater than those being charged by the respective assigning Lender prior to such assignment, then the Borrower shall not be obligated to pay such greater increased costs (although the Borrower shall be obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective assignment).

(c) Nothing in this Agreement shall prevent or prohibit any Lender from pledging its Loans and Notes hereunder to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank and, with the consent of the Administrative Agent, any Lender which is a fund may pledge all or any portion of its Notes or Loans to its trustee or to a collateral agent providing credit or credit support to such Lender in support of its obligations to its trustee or such collateral agent, as the case may be. No pledge pursuant to this clause (c) shall release the transferor Lender from any of its obligations hereunder.

11.05 No Waiver; Remedies Cumulative. No failure or delay on the part of any Agent or any Lender or any holder of any Note in exercising any right, power or privilege

hereunder or under any other Credit Document and no course of dealing between the Borrower or any other Credit Party and any Agent or any Lender or the holder of any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and remedies herein or in any other Credit Document expressly provided are cumulative and not exclusive of any rights, powers or remedies which any Agent or any Lender or the holder of any Note would otherwise have. No notice to or demand on any Credit Party in any case shall entitle any Credit Party to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Agent or any Lender or the holder of any Note to any other or further action in any circumstances without notice or demand.

11.06 Payments Pro Rata. (a) Except as otherwise provided in this Agreement, the Administrative Agent agrees that promptly after its receipt of each payment from or on behalf of the Borrower in respect of any Obligations hereunder, it shall distribute such payment to the Lenders (other than any Lender that has consented in writing to waive its pro rata share of any such payment) pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received.

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

(c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 11.06(a) and (b) shall be subject to the express provisions of this Agreement which require, or permit, differing payments to be made to Non-Defaulting Lenders as opposed to Defaulting Lenders.

11.07 Calculations; Computations.(a) The financial statements to be furnished to the Lenders pursuant hereto shall be made and prepared in accordance with generally accepted accounting principles in the United States consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise disclosed in writing by the Borrower to the Lenders), provided that except as otherwise specifically provided herein, all computations and definitions (including accounting terms) used in determining compliance with Sections 7.08 and 7.09, shall utilize accounting principles and policies in conformity with those used to prepare the historical financial statements referred to in Section 5.05(a).

(b) All computations of interest on Loans hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. All computations of Fees hereunder shall be made on the basis of a year of 365/366 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such Fees are payable.

11.08 GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE. THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EACH CASE WHICH ARE LOCATED IN THE COUNTY OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH CREDIT PARTY HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH CREDIT PARTY HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH COURTS LACK PERSONAL JURISDICTION OVER IT, AND AGREES NOT TO PLEAD OR CLAIM, IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENTS BROUGHT IN ANY OF THE AFOREMENTIONED COURTS, THAT SUCH COURTS LACK PERSONAL JURISDICTION OVER IT. EACH CREDIT PARTY FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO EACH CREDIT PARTY AT ITS ADDRESS SET FORTH OPPOSITE ITS SIGNATURE BELOW, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY AGENT, ANY LENDER OR THE HOLDER OF ANY NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANY CREDIT PARTY IN ANY OTHER JURISDICTION.

(a) EACH CREDIT PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT BROUGHT IN THE COURTS REFERRED TO IN CLAUSE (a) ABOVE AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

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

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

11.10 Effectiveness. This Agreement shall become effective on the date (the “Effective Date”) on which (i) the Borrower, each Lender and the Administrative Agent shall have signed a counterpart hereof (whether the same or different counterparts) and shall have delivered (including by way of facsimile) the same to the Administrative Agent at the Notice Office or, in the case of the Lenders, shall have given the Administrative Agent telephonic (confirmed in writing), written or telex notice (actually received) at such office that same has been signed and mailed to it and (ii) the conditions contained in Section 4 are met to the satisfaction of the Administrative Agent. Unless the Administrative Agent has received actual notice from any Lender that the conditions contained in Section 4 have not been met to its reasonable satisfaction, upon the satisfaction of the condition described in clause (i) of the immediately preceding sentence and upon the Administrative Agent’s good faith determination that the conditions described in clause (ii) of the immediately preceding sentence have been met, then the Effective Date shall have been deemed to have occurred, regardless of any subsequent determination that one or more of the conditions thereto had not been met (although the occurrence of the Effective Date shall not release the Borrower from any liability for failure to satisfy one or more of the applicable conditions contained in Section 4). The Administrative Agent will give the Borrower and each Lender prompt written notice of the occurrence of the Effective Date.

11.11 Headings Descriptive. The headings of the several sections and subsections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

11.12 Amendment or Waiver. Neither this Agreement nor any other Credit Document nor any terms hereof or thereof may be changed, waived, discharged or terminated unless such change, waiver, discharge or termination is in writing signed by the respective Credit Parties party thereto and the Required Lenders, provided that no such change, waiver, discharge or termination shall, without the consent of each Lender (other than a Defaulting Lender) (with Obligations being directly affected thereby in the case of following clause (i)), (i) extend the final scheduled maturity of any Loan or Note beyond the Maturity Date, or reduce the rate or extend the time of payment of interest or Fees (it being understood that any amendment or modification to the financial definitions in this Agreement or to Section 11.07(a) shall not constitute a reduction in the rate of interest or Fees for the purposes of this clause (i)), or reduce the principal amount thereof, (ii) amend, modify or waive any provision of this Section 11.12 (except for technical amendments with respect to additional extensions of credit under this Agreement of the type which afford the protections to such additional extensions of credit provided to the Commitments on the Effective Date), (iii) reduce the percentage specified in the definition of Required Lenders or (iv) consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement; provided further, that no such change, waiver, discharge or termination shall (1) increase the Commitment of any Lender over the amount thereof then in effect without the consent of such Lender (it being understood and agreed that waivers or modifications of conditions precedent, covenants (including, without limitation, by means of modifications to the financial definitions or modifications in the method of calculation of any financial covenants), Defaults or Events of Default shall not constitute an

increase of the Commitment of any Lender, and that an increase in the available portion of any Commitment of any Lender shall not constitute an increase in the Commitment of such Lender), or (2) without the consent of each Agent affected thereby, amend, modify or waive any provision of Section 10 as same applies to such Agent or any other provision as same relates to the rights or obligations of such Agent.

11.13 Survival. All indemnities set forth herein including, without limitation, in Sections 1.08, 1.09, 3.04, 11.01 and 11.06 shall, survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the Loans.

11.14 Domicile of Loans. Each Lender may transfer and carry its Loans at, to or for the account of any office, Subsidiary or Affiliate of such Lender. Notwithstanding anything to the contrary contained herein, to the extent that a transfer of Loans pursuant to this Section 11.14 would, at the time of such transfer, result in increased costs under Section 1.08, 1.09 or 3.04 from those being charged by the respective Lender prior to such transfer, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective transfer).

11.15 Confidentiality. (a) Subject to the provisions of clause (b) of this Section 11.15, each Lender agrees that it will not disclose without the prior consent of the Borrower (other than to its employees, auditors, advisors or counsel or to another Lender if the Lender or such Lender’s holding or parent company in its sole discretion determines that any such party should have access to such information, provided such Persons shall be subject to the provisions of this Section 11.15 to the same extent as such Lender) any information with respect to the Borrower or any of its Subsidiaries which is now or in the future furnished pursuant to this Agreement or any other Credit Document and which is designated by the Borrower to the Lenders in writing as confidential, provided that any Lender may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to any municipal, state or Federal regulatory body having or claiming to have jurisdiction over such Lender or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (c) as may be required or appropriate in respect to any summons or subpoena or in connection with any litigation, (d) in order to comply with any law, order, regulation or ruling applicable to such Lender, (e) to any Agent, (f) to any prospective or actual transferee or participant in connection with any contemplated transfer or participation of any of the Notes or Commitments or any interest therein by such Lender, provided that such prospective transferee agrees to be subject to the provisions contained in this Section 11.15 and (g) to any nationally recognized rating agency that requires access to information about such Lender’s investment portfolio in connection with ratings issued to such Lender.

(b) Each Credit Party hereby acknowledges and agrees that each Lender may share with any of its Affiliates any information related to the Borrower or any of its Subsidiaries (including, without limitation, any nonpublic customer information regarding the creditworthiness of the Borrower and its Subsidiaries), provided such Persons shall be subject to the provisions of this Section 11.15 to the same extent as such Lender.

(c) Each Credit Party hereby represents and acknowledges that, to the best of its knowledge, no Agent nor any Lender, nor any employees or agents of, or other persons affiliated with, any Agent or any Lender, have directly or indirectly made or provided any statement (oral or written) to such Credit Party or to any of their respective employees or agents, or other persons affiliated with or related to such Credit Party (or, so far as such Credit Party is aware, to any other Person), as to the potential tax consequences of this Agreement, any other Credit Document or any of the transactions contemplated hereby or thereby.

(d) Neither the Agents, the Lenders or any of their respective affiliates nor any Credit Party provide accounting, tax, or legal advice and each party has consulted, or will consult, its own advisors regarding its participation in the transactions contemplated by this Agreement. Notwithstanding anything provided herein, in the other Credit Documents or in any other document or agreement relating to the transactions contemplated herein and in the other Credit Documents, and any express or implied claims of exclusivity or proprietary rights, the Agents, the Lenders and each of the Credit Parties hereby agree and acknowledge that each Credit Party, the Agents, the Lenders and any of their respective affiliates (and each of their respective employees, representatives or other agents) are authorized to disclose to any and all persons, beginning immediately upon commencement of their discussions regarding such transactions and without limitation of any kind, the U.S. federal, state, or local tax treatment and tax structure of such transactions, and all materials of any kind (including opinions or other tax analyses) that are provided by either any Credit Party, any Agent, any Lender or any of their respective affiliates (and any of their respective employees, representatives or other agents) to any other such party relating to such tax treatment and tax structure, except to the extent that such disclosure is subject to restrictions reasonably necessary to comply with securities laws. For purposes of this authorization, “tax treatment” of a transaction means the purported or claimed tax treatment of the transaction and “tax structure” of a transaction means any fact that may be relevant to understanding the purported or claimed tax treatment of the transaction. Nothing herein is intended to imply that any oral or written statement as to any potential tax consequences that are related to, or may result from, the transactions contemplated by the Agreement and the other Credit Documents have been made or provided to, or for the benefit of, any Agent, Lender, Credit Party or any of their respective affiliates by any other such party.

11.16 Register. The Borrower hereby designates the Administrative Agent to serve as the Borrower’s agent, solely for purposes of this Section 11.16, to maintain a register (the “Register”) on which it will record the Commitments from time to time of each of the Lenders, the Loans made by each of the Lenders and each repayment in respect of the principal amount of the Loans of each Lender. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error. Failure to make any such recordation, or any error in such recordation shall not affect the Borrower’s obligations in respect of such Loans. With respect to any Lender, the transfer of the Commitments of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitments shall not be effective until such transfer is recorded on the Register maintained by the Administrative Agent with respect to ownership of such Commitments and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitments and Loans shall remain owing to the transferor. The registration of assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and delivered

Assignment and Assumption Agreement pursuant to Section 11.04(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the Administrative Agent for acceptance and registration of assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note evidencing such Loan, and thereupon one or more new Notes in the same aggregate principal amount shall be issued to the assigning or transferor Lender and/or the new Lender. The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 11.16.

12.01 Guaranty. In order to induce the Lenders to enter into this Agreement and to extend credit hereunder and in recognition of the direct benefits to be received by each Guarantor from the proceeds of the Loans, each Guarantor hereby agrees with the Lenders as follows: Each Guarantor hereby unconditionally and irrevocably guarantees, as primary obligor and not merely as surety the full and prompt payment when due in cash, whether upon maturity, acceleration or otherwise, of any and all of the Guaranteed Obligations to the Guaranteed Creditors. If any or all of the Guaranteed Obligations to the Guaranteed Creditors becomes due and payable hereunder, each Guarantor unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, together with any and all expenses which may be incurred by the Guaranteed Creditors in collecting any of the Guaranteed Obligations. This Guaranty is a continuing one and the Guaranteed Obligations shall be conclusively presumed to have been created in reliance hereon. If claim is ever made upon any Guaranteed Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations and any of the Guaranteed Creditors repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such Guaranteed Creditor or any of its property or (ii) any settlement or compromise of any such claim effected by such Guaranteed Creditor with any such claimant (including the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon the Guarantors, notwithstanding any revocation of this Guaranty or any other instrument evidencing any liability of the Borrower, and each Guarantor shall be and remain liable to the Guaranteed Creditors hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee.

12.02 Bankruptcy. Additionally, each Guarantor unconditionally and irrevocably guarantees the payment of any and all of the Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the Borrower upon the occurrence of any of the events specified in Section 8.05, and unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand.

12.03 Nature of Liability. The liability of each Guarantor hereunder is exclusive and independent of any security for or other guaranty of the Guaranteed Obligations whether executed by any Guarantor, any other guarantor or by any other party, and the liability of each Guarantor hereunder is not affected or impaired by (a) any direction as to application of payment by any Borrower or by any other party, or (b) any other continuing or other guaranty,

undertaking or maximum liability of a guarantor or of any other party as to the Guaranteed Obligations, or (c) any payment on or in reduction of any such other guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by the Borrower, or (e) any payment made to the Guaranteed Creditors on the Guaranteed Obligations which any such Guaranteed Creditor repays to the Borrower pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding.

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

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

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

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

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

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

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

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

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

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

12.06 Reliance. It is not necessary for the Guaranteed Creditors to inquire into the capacity or powers of the Borrower or the officers, directors, partners or agents acting or purporting to act on its or their behalf, and any Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

12.07 Rights of Contribution. (a) The Guarantors hereby agree, as between themselves, that if any Guarantor shall become an Excess Funding Guarantor (as defined below) by reason of the payment by such Guarantor of any Guaranteed Obligations, each other Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the next sentence), pay to such Excess Funding Guarantor an amount equal to such Guarantor’s Pro Rata Share (as defined below and determined, for this purpose, without reference to the properties, debts and liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of such Guaranteed Obligations. The payment obligation of a Guarantor to any Excess Funding Guarantor under this Section shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Guarantor under the other provisions of this Article 14 and such Excess Funding Guarantor shall not exercise any right or remedy with respect to such excess until payment in full of all Guaranteed Obligations.

(b) For purpose of this Section, (i) “Excess Funding Guarantor” means, in respect of any Guaranteed Obligations, a Guarantor that has paid an amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii) “Excess Payment” means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such Guaranteed Obligations and (iii) “Pro Rata Share” means, for any Guarantor, the ratio (expressed as percentage) or (x) the amount by which the aggregate present fair saleable value of all properties of such Guarantor (excluding any shares of stock of any other Guarantor) exceeds the amount of all the debts and liabilities of such Guarantor (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of such Guarantor hereunder and any obligations of any other Guarantor that have been Guaranteed by

such Guarantor) to (y) the amount by which the aggregate fair saleable value of all properties of all the Guarantors exceeds the amount of all the debts and liabilities (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of the Borrower and the Guarantors hereunder and under the other Credit Documents) of all the Guarantors, determined (A) with respect to any Guarantor that is a party hereto on the Effective Date, as of the Effective Date, and (B) with respect to any other Guarantor, as of the date such Guarantor becomes a Guarantor hereunder.

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

(b) Each Guarantor waives all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Guaranty, and notices of the existence, creation or incurring of new or additional Guaranteed Obligations. Each Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and agrees that the Guaranteed Creditors shall have no duty to advise any Guarantor of information known to them regarding such circumstances or risks.

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

(d) Each Guarantor warrants and agrees that each of the waivers set forth above is made with full knowledge of its significance and consequences and that if any of such waivers are determined to be contrary to any applicable law of public policy, such waivers shall be effective only to the maximum extent permitted by law.

12.09 Payment. All payments made by any Guarantor pursuant to this Section 12 shall be made in Dollars in immediately available funds. All payments made by any Guarantor pursuant to this Section 12 will be made without setoff, counterclaim or other defense, and shall be subject to the provisions of Sections 3.03 and 3.04.

12.10 Savings Clause. Each Lender and each Guarantor hereby confirms that it is its intention that this Guaranty not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, each Lender and each Guarantor hereby irrevocably agrees that Guaranteed Obligations guaranteed by each Guarantor under this Guaranty shall be limited to such amount as will, after giving effect to such maximum amount and all of such Guarantor’s other (contingent or otherwise) liabilities that are relevant under such laws (but excluding, to the maximum extent permitted by applicable law, any liabilities of a Guarantor arising under any other indebtedness that is subordinated to the Guaranteed Obligations or any obligations under this Guarantee), and after giving effect to any rights to contribution pursuant to Section 12.07 hereof, result in the Guaranteed Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance.

IN WITNESS WHEREOF, each of the parties hereto has caused a counterpart of this Agreement to be duly executed and delivered as of the date first above written.
