SECTION 2.02 Procedures for Advances; Limitations on Borrowings.

(a) The Borrower may request Advances by giving notice (a “Notice of Borrowing”) to the Administrative Agent (which shall promptly advise each Lender of its receipt thereof) not later than 10:00 A.M. on the third Business Day prior to the date of any proposed borrowing of Eurodollar Advances and on the date of any proposed borrowing of Base Rate Advances. Each Notice of Borrowing shall be sent by facsimile and shall be in substantially the form of Exhibit B, specifying therein (i) the requested date of borrowing (which shall be a Business Day), (ii) the Type of Advances requested, (iii) the aggregate principal amount of the requested Advances and (iv) in the case of a borrowing of Eurodollar Advances, the initial Interest Period therefor. Each Lender shall, before 12:00 noon on the date of such borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 8.02, in same day funds, such Lender’s ratable portion of the requested borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent’s aforesaid address.

(b) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. If a Notice of Borrowing requests Eurodollar Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure of the Borrower to fulfill on or before the requested borrowing date the applicable conditions set forth in Article III, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the requested Advance to be made by such Lender.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any requested borrowing (or, in the case of a borrowing of Base Rate Advances to be made on the same Business Day as the Administrative Agent’s receipt of the relevant Notice of Borrowing, prior to 10:30 A.M. on such Business Day) that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the requested borrowing date in accordance with Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable 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 Advances made in connection with such borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(d) The failure of any Lender to make the Advance to be made by it on any borrowing date shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on such date, but no Lender shall be responsible for the failure of any other Lender to make any Advance to be made by such other Lender.

(e) Each Borrowing of Base Rate Advances shall at all times be in an aggregate amount of $5,000,000 or a higher integral multiple of $1,000,000; and each Borrowing of Eurodollar Advances shall at all times be in an aggregate amount of $10,000,000 or a higher integral multiple of $1,000,000. Notwithstanding anything to the contrary contained herein, the Borrower may not have more than 20 Borrowings of Eurodollar Advances outstanding at any time.

-17-

SECTION 2.03 Facility Fee. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, a facility fee at a rate per annum equal to the Facility Fee Rate on such Lender’s Pro Rata Share of the Aggregate Commitment Amount (or, after such Lender’s Termination Date, of the principal amount of all Outstanding Credit Extensions) for the period from the Effective Date to such Lender’s Termination Date (or, if later, the date on which all obligations of the Borrower to such Lender hereunder have been paid in full and such Lender has no participation interests in any LC Obligations), payable on the last day of each March, June, September and December and on the such Lenders’ Termination Date (and, if applicable, thereafter on demand).

SECTION 2.04 Reduction of Commitment Amounts.

(a) The Borrower shall have the right, upon at least two Business Days’ notice to the Administrative Agent, to ratably reduce the respective Commitment Amounts of the Lenders in accordance with their Pro Rata Shares; provided that the Aggregate Commitment Amount may not be reduced to an amount that is less than the Outstanding Credit Extensions; and provided, further, that each partial reduction of the Commitment Amounts shall be in the aggregate amount of $10,000,000 or an integral multiple thereof. Any reduction of the Commitment Amounts pursuant to this Section 2.04 shall be permanent, except as expressly provided otherwise herein.

(b) The Borrower may at any time, upon at least two Business Days’ notice to the Administrative Agent, terminate the Commitments so long as the Borrower concurrently pays all of its outstanding obligations hereunder.

SECTION 2.05 Repayment of Advances. The Borrower shall repay all outstanding Advances made by each Lender, and all other obligations of the Borrower to such Lender hereunder, on such Lender’s Termination Date.

SECTION 2.06 Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, as follows:

(a) At all times such Advance is a Base Rate Advance, a rate per annum equal to the Alternate Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable quarterly on the last day of each March, June, September and December, on the date such Base Rate Advance is converted to a Eurodollar Advance or paid in full and on such Lender’s Termination Date (and, if applicable, thereafter on demand).

(b) At all times such Advance is a Eurodollar Advance, a rate per annum equal to the sum of the Adjusted LIBO Rate for each applicable Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of each Interest Period for such Eurodollar Advance (and, if any Interest Period for such Advance is six months, on the day that is three months after the first day of such Interest Period) or, if earlier, on the date such Eurodollar Advance is converted to a Base Rate Advance or paid in full and on such Lender’s Termination Date (and, if applicable, thereafter on demand).

SECTION 2.07 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Advance:

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

-18-

(b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Advances (or its Advances) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any notice that requests the conversion of any Advance to, or continuation of any Advance as, a Eurodollar Advance shall be ineffective and (ii) if any Notice of Borrowing requests a Eurodollar Advance, such Advance shall be made as a Base Rate Advance.

SECTION 2.08 Interest Rate Determination.

(a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of each applicable interest rate determined by the Administrative Agent for purposes of Section 2.06(a) or (b).

(b) If, with respect to any Borrowing of Eurodollar Advances, the Majority Lenders notify the Administrative Agent that the Adjusted LIBO Rate for any Interest Period for such Advances will not adequately reflect the cost to such Majority Lenders of making, funding or maintaining their respective Eurodollar Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon

(i) each Eurodollar Advance will automatically, on the last day of the then existing Interest Period therefor (unless prepaid or converted to a Base Rate Advance prior to such day), convert into a Base Rate Advance, and

(ii) the obligation of the Lenders to make, continue or convert into Eurodollar Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.09 Continuation and Conversion of Advances.

(a) The Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 10:00 A.M. on the third Business Day prior to the date of any proposed continuation of or conversion into Eurodollar Advances, and on the date of any proposed conversion into Base Rate Advances, and subject to the provisions of Sections 2.08 and 2.12, continue Eurodollar Advances for a new Interest Period or convert a Borrowing of Advances of one Type into Advances of the other Type; provided that any continuation of Eurodollar Advances or conversion of Eurodollar Advances into Base Rate Advances shall be made on, and only on, the last day of an Interest Period for such Eurodollar Advances, unless, in the case of such a conversion, the Borrower shall also reimburse the Lenders pursuant to Section 8.04(b) on the date of such conversion. Each such notice of a continuation or conversion shall, within the restrictions specified above, specify (i) the date of such continuation or conversion, (ii) the Advances to be continued or converted, and (iii) in the case of continuation of or conversion into Eurodollar Advances, the duration of the Interest Period for such Advances.

(b) If the Borrower fails to select the Type of any Advance or the duration of any Interest Period for any Borrowing of Eurodollar Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and Section 2.09(a), the Administrative Agent will

-19-

forthwith so notify the Borrower and the Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, convert into Base Rate Advances.

SECTION 2.10 Prepayments. The Borrower may, upon notice to the Administrative Agent not later than 10:00 A.M. at least three Business Days prior to any prepayment of Eurodollar Advances or on the date of any prepayment of Base Rate Advances, in each case stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall, prepay the outstanding principal amounts of the Advances made as part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided that (i) each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Eurodollar Advances and $5,000,000 or a higher integral multiple of $1,000,000 in the case of any prepayment of Base Rate Advances (provided that if the aggregate amount of Advances made pursuant to Section 2.16 as a result of a drawing under a Facility LC is not $5,000,000 or a higher integral multiple of $1,000,000, then the next prepayment of Base Rate Advances shall be in an aggregate amount that causes the aggregate principal amount of all Base Rate Advances to be either (A) zero or (B) $5,000,000 or a higher integral multiple of $1,000,000) and (ii) in the case of any such prepayment of a Eurodollar Advance, the Borrower shall be obligated to reimburse the Lenders pursuant to Section 8.04(b) on the date of such prepayment.

SECTION 2.11 Increased Costs. If any Change in Law shall:

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

(ii) impose on any Lender or any LC Issuer or the London interbank market any other condition affecting this Agreement or Eurodollar Advances made by such Lender or any Facility LC or participation therein; or

(iii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes and (B) Other Connection Taxes on gross or net income, profits or revenue (including value-added or similar Taxes)) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making or maintaining any Eurodollar Advance (or of maintaining its obligation to make any such Advance) or to increase the cost to such Lender, any LC Issuer or such other Recipient of participating in, issuing or maintaining any Facility LC or to reduce the amount of any sum received or receivable by such Lender, such LC Issuer or such other Recipient hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender, such LC Issuer or such other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, such LC Issuer or other Recipient for such additional costs incurred or reduction suffered.

(b) If any Lender or any LC Issuer determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such LC Issuer’s capital or on the capital of such Lender’s or such LC Issuer’s holding company, if any, as a consequence of this Agreement or the Advances made by, or participations in Facility LCs held by, such Lender, or the Facility LCs issued by such LC Issuer, to a level below that which such Lender or such LC

-20-

Issuer or such Lender’s or such LC Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such LC Issuer’s policies and the policies of such Lender’s or such LC Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such LC Issuer such additional amount or amounts as will compensate such Lender or such LC Issuer or such Lender’s or such LC Issuer’s holding company for any such reduction suffered.

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

(d) Failure or delay on the part of any Lender or any LC Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such LC Issuer’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an LC Issuer pursuant to this Section for any increased costs or reductions incurred more than 90 days prior to the date that such Lender or such LC Issuer notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such LC Issuer’s intention to claim compensation therefor; provided, further, that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof, provided that such demand is made within 90 days after the implementation of such retroactive Change in Law.

SECTION 2.12 Illegality. Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Advances or to fund or maintain Eurodollar Advances hereunder, (i) the obligation of such Lender to make, continue or convert Advances into Eurodollar Advances shall be suspended (subject to the following paragraph of this Section 2.12) until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist and (ii) all Eurodollar Advances of such Lender then outstanding shall, on the last day of the then applicable Interest Period (or such earlier date as such Lender shall designate upon not less than five Business Days’ prior written notice to the Administrative Agent), be automatically converted into Base Rate Advances.

If the obligation of any Lender to make, continue or convert into Eurodollar Advances has been suspended pursuant to the preceding paragraph, then, unless and until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, (i) all Advances that would otherwise be made by such Lender as Eurodollar Advances shall instead be made as Base Rate Advances and (ii) to the extent that Eurodollar Advances of such Lender have been converted into Base Rate Advances pursuant to the preceding paragraph or made instead as Base Rate Advances pursuant to the preceding clause (i), all payments and prepayments of principal that would have otherwise been applied to such Eurodollar Advances of such Lender shall be applied instead to such Base Rate Advances of such Lender.

SECTION 2.13 Payments and Computations.

(a) The Borrower shall make each payment hereunder not later than 10:00 A.M. on the day when due in U.S. dollars to the Administrative Agent at its address referred to in Section 8.02 in same day funds without setoff, counterclaim or other deduction. The Administrative Agent will promptly

-21-

thereafter cause to be distributed like funds relating to the payment of principal, interest, facility fees and letter of credit fees ratably (other than amounts payable pursuant to Section 2.02(b), 2.11, 2.14 or 8.04(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(d), from the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent any payment owed to such Lender by the Borrower is not made when due hereunder, to charge from time to time against any of the Borrower’s accounts with such Lender any amount so due. Each Lender agrees to notify the Borrower promptly after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application.

(c) All computations of interest based on the Prime Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all other computations of interest and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of any interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of a Eurodollar Advance to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due by the Borrower to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

(f) Notwithstanding anything to the contrary contained herein, any amount payable by the Borrower hereunder that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to the fullest extent permitted by law) bear interest from the date when due until paid in full at a rate per annum equal at all times to the Alternate Base Rate plus the Applicable Margin in effect from time to time plus 2%, payable upon demand.

SECTION 2.14 Taxes.

-22-

(a) Each payment by or on account of the Borrower under this Agreement shall be made without withholding for any Taxes, unless such withholding is required by any law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by the Borrower shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section), the applicable Recipient receives the amount it would have received had no such withholding been made.

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

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

(d) The Borrower shall indemnify each Recipient for any Indemnified Taxes that are paid or payable by such Recipient in connection with this Agreement (including amounts paid or payable under this Section 2.14(d)) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.14(d) shall be paid within 10 days after the Recipient delivers to the Borrower a certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient and describing in reasonable detail the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent.

(e) Each Lender shall severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes, only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so) attributable to such Lender that are paid or payable by the Administrative Agent in connection with this Agreement and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority, as a result of the failure by such Lender to deliver, or as a result of the inaccuracy, inadequacy or deficiency of, any documentation required to be delivered by such Lender to the Borrower or the Administrative Agent pursuant to Section 2.14(f); provided that no Lender shall be liable for the portion of any interest, expenses or penalties that are found by a final non-appealable decision of a court of competent jurisdiction to have resulted from the Administrative Agent’s gross negligence or willful misconduct. The indemnity under this Section 2.14(e) shall be paid within 10 days after the Administrative Agent delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent and, if requested by the applicable Lender, a copy of any notice of claim of the relevant Governmental Authority at the time the Administrative Agent makes a written demand for indemnification. Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(f) Status of Lenders.

(i) Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding Tax with respect to any payments under this Agreement shall promptly deliver to the Borrower and the Administrative Agent, at the time or times

-23-

reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall promptly deliver such other documentation prescribed by law or at the time or times reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.14(f)(ii)(A) through (E) and Section 2.14(f)(iii) below) shall not be required if the Lender notifies the Borrower and the Administrative Agent that the Lender is waiving its rights under this Section 2.14 to indemnification of the withholding Taxes to which the requested documentation relates. Upon the reasonable request of the Borrower or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 2.14(f). If any form or certification previously delivered pursuant to this Section expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify the Borrower and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii) Without limiting the generality of the foregoing, if the Borrower is a U.S. Person, any Lender with respect to the Borrower shall, if it is legally eligible to do so, deliver to the Borrower and the Administrative Agent (in such number of copies reasonably requested by the Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto, duly completed and executed copies of whichever of the following is applicable:

(A) in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax;

(B) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(C) in the case of a Non-U.S. Lender for whom payments under this Agreement constitute income that is effectively connected with such Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI;

(D) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) IRS Form W-8BEN and (2) a certificate substantially in the appropriate form of Exhibit E (a “U.S. Tax Certificate”) to the effect that such Lender is not (a) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code (c) a “controlled foreign corporation”

-24-

described in Section 881(c)(3)(C) of the Code and (d) conducting a trade or business in the United States with which the relevant interest payments are effectively connected;

(E) in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under this Agreement (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of each such beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Non-U.S. Lender is a partnership providing an IRS Form W-8IMY on behalf of itself and one or more of its partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Non-U.S. Lender may provide a U.S. Tax Certificate on behalf of such partners; or

(F) any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation necessary to enable the Borrower or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld.

(iii) If a payment made to a Lender under this Agreement would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has or has not complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.14(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g) If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.14 (including additional amounts paid pursuant to this Section 2.14), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund, including additional amounts paid pursuant to this Section 2.14), net of all out-of-pocket expenses (including any Taxes payable on account of such refund) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid to such indemnified party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 2.14(g), in no event will any indemnified party be required to pay any amount to any indemnifying party pursuant to this Section 2.14(g) if such payment would place such indemnified party in a less favorable position (on a net after-Tax basis) than such indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.14(g) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

-25-

(h) Without prejudice to the survival of any other agreement of the Borrower or any Lender hereunder, the agreements and obligations of the Borrower and the Lenders contained in this Section 2.14 shall survive the payment in full of principal and interest hereunder and the termination of this Agreement; provided that no Lender shall be entitled to demand any payment from the Borrower under this Section 2.14 more than one year following the payment to or for the account of such Lender of all other amounts payable by the Borrower hereunder to such Lender and the termination of such Lender’s Commitment; provided, further, that the foregoing proviso shall in no way limit the right of any Lender to demand or receive any payment under this Section 2.14 to the extent that such payment relates to the retroactive application of any Taxes or Other Taxes if such demand is made within one year after the implementation of such Taxes or Other Taxes.

(i) For purposes of Section 2.14(e) and (f), the term “Lender” includes any LC Issuer.

SECTION 2.15 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by it to the Borrower or its participation interest in any Facility LC issued for the account of the Borrower (other than pursuant to Section 2.02(b), 2.11, 2.14, 2.17.7 or 8.04(b)) in excess of its ratable share of payments on account of the Advances to the Borrower and LC Obligations obtained by all Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances and/or LC Obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.15 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

SECTION 2.16 Facility LCs.

SECTION 2.16.1 Issuance. Each LC Issuer agrees, on the terms and conditions set forth in this Agreement (including the limitations set forth in Sections 2.01, 2.19 and 3.02), upon the request of the Borrower, to issue standby and direct pay letters of credit in a form reasonably acceptable to the applicable LC Issuer and to extend, increase or otherwise modify Facility LCs (“Modify”, and each such action a “Modification”) for the Borrower, from time to time from the date of this Agreement to the Termination Date; provided that (a) the aggregate amount of LC Obligations owed by the Borrower to any LC Issuer shall not exceed the amount of such LC Issuer’s LC Pro Rata Share of the LC Sublimit (or such higher amount agreed upon in writing between the Borrower and such LC Issuer); (b) the aggregate amount of all LC Obligations shall not exceed the LC Sublimit; (c) the stated amount of all Facility LCs that have scheduled expiry dates after the next scheduled Termination Date for any Lender plus the aggregate principal amount of all Eurodollar Advances that have Interest Periods ending after such Termination Date shall not exceed the remainder of (i) the Aggregate Commitment Amount minus (ii) the aggregate amount of the Commitments that are scheduled to terminate on such Termination Date; and (d) no LC Issuer shall be obligated to issue or Modify any Facility LC if (i) any order, judgment or decree of any court or other governmental authority shall by its terms purport to enjoin or restrain such LC Issuer from issuing such Facility LC or (ii) any applicable law, or any request or directive from any governmental authority having jurisdiction over such LC Issuer, shall prohibit,

-26-

or request or direct that such LC Issuer refrain from, the issuance of letters of credit generally or of such Facility LC in particular. Facility LCs may be issued for any proper limited liability company (or, if applicable, corporate) purpose. Each Facility LC shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Facility LC (or, in the case of any renewal or extension thereof, one year after such renewal or extension and provided that such Facility LC may contain customary “evergreen” provisions pursuant to which the expiry date is automatically extended by a specific time period unless such LC Issuer gives notice to the beneficiary of such Facility LC at least a specified time period prior to the expiry date then in effect) and (ii) the date that is five Business Days prior to the next scheduled Termination Date in effect at the time of issuance, renewal or extension; provided that with the prior consent of the Administrative Agent and the applicable LC Issuer, such LC Issuer may issue or extend a Facility LC with a later expiration date so long as on or before the date which is seven Business Days prior to the last scheduled Termination Date, whether or not an Event of Default exists, the Borrower shall deposit cash collateral with the Administrative Agent in accordance with Section 2.16.12 in respect of all outstanding Facility LCs with an expiration date later than five Business Days prior to the last scheduled Termination Date. Any Facility LC theretofore issued which contains an “evergreen” or similar automatic extension feature shall, unless the Borrower shall have notified the Administrative Agent and the applicable LC Issuer in writing not less than thirty (30) days (or such shorter period as may be acceptable to the applicable LC Issuer in its sole discretion or such longer period as may be required by the beneficiary of such Facility LC) prior to the date that such Facility LC is scheduled to be automatically extended that the Borrower desires that such Facility LC not be so extended, be automatically extended in accordance with the terms thereof subject to the applicable LC Issuer’s right not to so extend if the conditions precedent to the issuance of such Facility LC would not be satisfied. If the Borrower is required to provide an amount of cash collateral hereunder as a result of an approaching Termination Date, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Facility LCs have expired and all related LC Obligations are satisfied in full. By their execution of this Agreement, the parties hereto agree that on the Effective Date (without any further action by any Person), each Existing Letter of Credit shall be deemed to have been issued under this Agreement and the rights and obligations of the issuer and the account party thereunder shall be subject to the terms hereof.

SECTION 2.16.2 Participations. Upon the issuance or Modification by an LC Issuer of a Facility LC in accordance with this Section 2.16 (or, in the case of the Existing Letters of Credit, on the Effective Date), the applicable LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share; provided, no Lender shall be deemed to purchase from such LC Issuer a participation in any Facility LC in excess of the amount that would cause the aggregate amount of such Lender’s (a) Advances to the Borrower and (b) participations in Facility LCs to exceed such Lender’s Commitment Amount.

SECTION 2.16.3 Notice. Subject to Section 2.16.1, the Borrower shall give the applicable LC Issuer notice prior to 11:00 A.M. at least five Business Days (or such lesser time as the applicable LC Issuer may agree) prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the Foreign Currency in which the Borrower proposes such Facility LC be denominated (which Foreign Currency shall be acceptable to the applicable LC Issuer), the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the applicable LC

-27-

Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification by an LC Issuer of any Facility LC shall, in addition to the applicable conditions precedent set forth in Article III (the satisfaction of which an LC Issuer shall have no duty to ascertain; provided that no LC Issuer shall issue a Facility LC if such LC Issuer shall have received written notice (which has not been rescinded) from the Administrative Agent or any Lender that any applicable condition precedent to the issuance or modification of such Facility LC has not been satisfied and, in fact, such condition precedent is not satisfied at the requested time of issuance), be subject to the conditions precedent that such Facility LC shall be satisfactory to the applicable LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as such LC Issuer shall have reasonably requested (each a “Facility LC Application”). In the event of any conflict (including any additional terms requiring the posting of collateral) between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

SECTION 2.16.4 LC Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, a letter of credit fee at a rate per annum equal to the LC Fee Rate on such Lender’s Pro Rata Share of the Dollar Equivalent of the undrawn stated amount of all Facility LCs for the period from the Effective Date to such Lender’s Termination Date (or, if later, the date on which such Lender has no participation interests in the Facility LCs), payable in arrears on the last day of each March, June, September and December and on the applicable Termination Date (and, if applicable, thereafter on demand). The Borrower also agrees to pay to the applicable LC Issuer for its own account (a) fronting fees in amounts and at times agreed upon between such LC Issuer and the Borrower and (b) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with such LC Issuer’s standard schedule for such charges as in effect from time to time.

SECTION 2.16.5 Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each Lender as to the Dollar Equivalent of the amount to be paid by such LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of an LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. Each Lender shall be unconditionally and irrevocably liable, without regard to the occurrence of the Termination Date (but subject to Sections 2.17 and 2.16.12), the occurrence of any Event of Default or Unmatured Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand for (i) such Lender’s Pro Rata Share of the Dollar Equivalent of the amount of each payment made by such LC Issuer under any Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.16.6 (subject to the provisions of Section 2.16.2), plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of such LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 A.M. on such day, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Rate for the first three days and, thereafter, at the Alternate Base Rate.

SECTION 2.16.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the applicable LC Issuer on or before the applicable LC

-28-

Payment Date in Dollars (or in the case of any Facility LC denominated in a Foreign Currency, the Dollar Equivalent thereof) for any amount to be paid by such LC Issuer upon any drawing under any Facility LC issued for the account of the Borrower, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence (as finally determined by a court of competent jurisdiction) of the applicable LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (ii) the applicable LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. If the Borrower fails to fully reimburse the applicable LC Issuer by 11:00 A.M. on an LC Payment Date, such LC Issuer shall promptly notify the Administrative Agent. Upon receipt of such notice, the Administrative Agent shall promptly notify each Lender of such LC Payment Date, the Dollar Equivalent of the amount of the unpaid Reimbursement Obligations and such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested Base Rate Advances to be disbursed on the applicable LC Payment Date in an amount equal to the Dollar Equivalent of the unpaid Reimbursements Obligations, without regard to the minimum and multiples specified for Base Rate Advances in Section 2.02(e), but subject to the conditions set forth in Article III. All Reimbursement Obligations that are not fully refinanced by the making of Base Rate Advances because the Borrower cannot satisfy the conditions set forth in Article III or for any other reason shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin plus 2%. The applicable LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligations in respect of any Facility LC issued by such LC Issuer, but only to the extent such Lender has made payment to such LC Issuer in respect of such Facility LC pursuant to Section 2.16.5.

SECTION 2.16.7 Obligations Absolute. The Borrower’s obligations under this Section 2.16 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have against any LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower agrees with the LC Issuers and the Lenders that the LC Issuers and the Lenders shall not be responsible for, and the Reimbursement Obligations in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. No LC Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by any LC Issuer or any Lender under or in connection with any Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction), shall be binding upon the Borrower and shall not put the applicable LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.16.7 is intended to limit the right of the Borrower to make a claim against an LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.16.6.

SECTION 2.16.8 Actions of LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice,

-29-

consent, certificate, affidavit, letter, facsimile, message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such LC Issuer. An LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Majority Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.16, an LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holder of a participation in any Facility LC. Each LC Issuer shall be permitted from time to time to designate one of its Affiliates to perform the duties to be performed by such LC Issuer hereunder with respect to Facility LCs denominated in Foreign Currencies. The provisions of this Section 2.16 shall apply to any such Affiliate mutatis mutandis.

SECTION 2.16.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, each LC Issuer and the Administrative Agent, and their respective directors, officers, agents and employees, from and against any claim, damage, loss, liability, cost or expense which such Lender, such LC Issuer or the Administrative Agent may incur (or which may be claimed against such Lender, such LC Issuer or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including any claim, damage, loss liability, cost or expense which the applicable LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to such LC Issuer hereunder (but nothing herein contained shall affect any right the Borrower may have against any Defaulting Lender) or (ii) by reason of or on account of such LC Issuer issuing any Facility LC that specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to such LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, any LC Issuer or the Administrative Agent for any claim, damage, loss, liability, cost or expense to the extent, but only to the extent, caused by (a) the willful misconduct or gross negligence (as finally determined by a court of competent jurisdiction) of an LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (b) an LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.16.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

SECTION 2.16.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the applicable LC Issuer, its Affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) or such LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder.

-30-

SECTION 2.16.11 Rights as a Lender. In its capacity as a Lender, each LC Issuer shall have the same rights and obligations as any other Lender.

SECTION 2.16.12 Cash Collateralization. In the event the Borrower is required to deposit cash collateral pursuant to the provisions of this Article II, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to 105% of the LC Obligations as of such date plus any accrued and unpaid interest thereon. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the LC Obligations. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the applicable LC Issuer for amounts paid by such LC Issuer in respect of a Facility LC for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Obligations. For the avoidance of doubt, no Lender shall have any reimbursement obligations under Section 2.16.5 in respect of any LC Obligations with respect to any Facility LC for which cash collateral has been deposited in accordance with the terms of this Agreement.

SECTION 2.16.13 Exchange Rate Date. The Administrative Agent will determine the Outstanding Credit Extensions on each Exchange Rate Date. If at any time the sum of such amounts exceeds the Aggregate Commitment Amount, whether as a result of fluctuations in currency exchange rates or otherwise, the Borrower shall immediately prepay the Advances in the amount of such excess. To the extent that, after the prepayment of all Advances an excess of the sum of such amounts over the Aggregate Commitment Amount still exists, the Borrower shall promptly cash collateralize the Facility LCs in the manner described in Section 2.16.12 in an amount sufficient to eliminate such excess.

SECTION 2.17 Extensions of Scheduled Termination Date.

SECTION 2.17.1 Extension Requests. The Borrower may, not more than two (2) times, by notice to the Administrative Agent (which shall promptly notify each Lender) not earlier than 60 and not later than 30 days prior to any anniversary of the Effective Date (each, an “Anniversary Date”), request that each Lender extend such Lender’s scheduled Termination Date then in effect (the “Existing Termination Date”) for an additional year from the Existing Termination Date, it being understood that the Termination Date shall not be later than the seventh anniversary of the Effective Date as a result of any such request.

SECTION 2.17.2 Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not later than the date (the “Notice Date”) that is 20 days prior to the applicable Anniversary Date, notify the Administrative Agent whether such Lender agrees to the requested extension of the Termination Date (each Lender that determines not to so extend its Termination Date, a “Declining Lender”). Any Lender that does not advise the Administrative Agent on or before the Notice Date that it has agreed to extend the Existing Termination Date shall be deemed to be a Declining Lender.

SECTION 2.17.3 Notification by Administrative Agent. The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section no later than the date 15 days prior to the applicable Anniversary Date.

-31-

SECTION 2.17.4 Additional Commitment Lenders. The Borrower shall have the right, at any time after a Lender has become a Declining Lender, to require such Declining Lender to assign and delegate its rights and obligations hereunder to one or more existing Lenders or other financial institutions that have agreed to assume such rights and obligations (each an “Additional Commitment Lender”) pursuant to, and in accordance with the requirements of, Section 8.07.

SECTION 2.17.5 Minimum Extension Requirement. If (and only if) the total of the Commitments of the Lenders (including Additional Commitment Lenders) that have agreed so to extend their Termination Date (each an “Extending Lender”) shall be more than 50% of the Aggregate Commitment Amount in effect immediately prior to the Anniversary Date, then, effective as of such date, the Termination Date of each Extending Lender (including any applicable Additional Commitment Lender) shall be extended to the date falling one year after the Existing Termination Date (except that, if such date is not a Business Day, such Termination Date as so extended shall be the next preceding Business Day).

SECTION 2.17.6 Conditions to Effectiveness of Extensions. Notwithstanding the foregoing, no extension of the Termination Date pursuant to this Section shall be effective unless:

(a) no Event of Default or Unmatured Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto;

(b) the representations and warranties of the Borrower contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and

(c) subject to Section 8.07(h), each LC Issuer shall have consented to such extension (which consent shall not be unreasonably delayed or withheld).

SECTION 2.17.7 Effect of Termination Date for some but not all Lenders. If the scheduled Termination Date for one or more Lenders (each an “Exiting Lender”) occurs on a date that is not the Termination Date for all Lenders, then on such Termination Date (a) the Borrower shall repay all amounts payable to the Exiting Lenders in accordance with Section 2.05, (b) the Commitments of the Exiting Lenders, and the participations of the Exiting Lenders in Facility LCs, shall terminate and (c) the Pro Rata Shares and the participations in Facility LCs of the remaining Lenders shall be redetermined pro rata in accordance with their respective Commitment Amounts after giving effect to the terminations described in clause (b) above; provided that if an Event of Default or Unmatured Event of Default exists on such Termination Date and either (i) the Borrower fails to pay in full all amounts payable to the Exiting Lenders or (ii) the Majority Lenders so request, then the participations of the Exiting Lenders in Facility LCs shall not terminate and no redetermination of the participations of the Lenders in Facility LCs shall be made until the earlier of the first Business Day after such Termination Date on which no Event of Default or Unmatured Event of Default exists and the date specified by the Majority Lenders in a notice to the Administrative Agent (which shall promptly advise each Lender). Nothing in the proviso clause to the preceding sentence shall affect the termination of the Commitment of an Exiting Lender on the relevant Termination Date (except with respect to such Exiting Lender’s participation in Facility LCs) or any Exiting Lender’s right to demand immediate repayment of all amounts owed to such Exiting Lender by the Borrower hereunder and to pursue remedies with respect thereto. Further, if at any time after the relevant Termination Date (x) the Borrower has not paid all principal, interest and facility fees payable to one or more Exiting Lenders hereunder and (y) the Lenders (excluding any Exiting Lender) elect to make

-32-

Advances, then all proceeds of such Advances shall be applied to pay the amounts owed by the Borrower to such Exiting Lenders (ratably based upon the amounts owed to such Lenders) until such principal, interest and facility fees have been paid in full.

SECTION 2.18 Optional Increase in Commitments. The Borrower may, from time to time, by means of a letter delivered to the Administrative Agent substantially in the form of Exhibit C, request that the Aggregate Commitment Amount be increased by an aggregate amount (for all such increases) not exceeding $1,000,000,000 by (a) increasing the Commitment Amount of one or more Lenders that have agreed to such increase (in their sole discretion) and/or (b) adding one or more commercial banks or other Persons as a party hereto (each an “Additional Lender”) with a Commitment Amount in an amount agreed to by any such Additional Lender; provided that (i) any increase in the Aggregate Commitment Amount shall be in an aggregate amount of $25,000,000 or a higher integral multiple of $1,000,000; (ii) no Additional Lender shall be added as a party hereto without the written consent of the Administrative Agent and the LC Issuers (which consents shall not be unreasonably withheld) or if an Event of Default or an Unmatured Event of Default exists; (iii) subject to Section 8.07(h), no such increase shall be effective without the written consent of the LC Issuers (which consent shall not be unreasonably withheld or delayed); and (iv) the Borrower may not request an increase in the Aggregate Commitment Amount unless the Borrower has delivered to the Administrative Agent (with a copy for each Lender) a certificate (A) stating that any applicable governmental authority has approved such increase, (B) attaching evidence, reasonably satisfactory to the Administrative Agent, of each such approval and (C) stating that the representations and warranties contained in Section 4.01 are correct on and as of the date of such certificate as though made on and as of such date and that no Event of Default or Unmatured Event of Default exists on such date. Any increase in the Aggregate Commitment Amount pursuant to this Section 2.18 shall be effective three Business Days after the date on which the Administrative Agent has received and accepted the applicable increase letter in the form of Annex 1 to Exhibit C (in the case of an increase in the Commitment Amount of an existing Lender) or assumption letter in the form of Annex 2 to Exhibit C (in the case of the addition of a commercial bank or other Person as a new Lender). The Administrative Agent shall promptly notify the Borrower and the Lenders of any increase in the Aggregate Commitment Amount pursuant to this Section 2.18 and of the Commitment Amount and Pro Rata Share of each Lender after giving effect thereto. The Borrower shall prepay any Advances outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 8.04(b)) to the extent necessary to keep the outstanding Advances ratable among the Lenders in accordance with any revised Pro Rata Shares arising from any non-ratable increase in the Commitment Amounts under this Section 2.18; provided that, notwithstanding any other provision of this Agreement, the Administrative Agent, the Borrower and each increasing Lender and Additional Lender, as applicable, may make arrangements satisfactory to such parties to cause an increasing Lender or an Additional Lender to temporarily hold risk participations in the outstanding Advances of the other Lenders (rather than fund its Pro Rata Share of all outstanding Advances concurrently with the applicable increase) with a view toward minimizing breakage costs and transfers of funds in connection with any increase in the Aggregate Commitment Amount. To the extent that any increase pursuant to this Section 2.18 is not expressly authorized pursuant to resolutions or consents delivered pursuant to Section 3.01(b)(i), the Borrower shall, prior to the effectiveness of such increase, deliver to the Administrative Agent a certificate signed by an authorized officer of the Borrower certifying and attaching the resolutions or consents that have been adopted to approve or consent to such increase.

SECTION 2.19 Defaulting Lenders.

Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

-33-

(a) fees shall cease to accrue on the unutilized portion of the Commitment of such Defaulting Lender pursuant to Section 2.03;

(b) the Commitment Amount and LC Obligations of such Defaulting Lender shall not be included in determining whether all Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 8.01); provided that, any waiver, amendment or modification (i) requiring the consent of all Lenders or each affected Lender, which affects such Defaulting Lender differently than other affected Lenders or (ii) under Section 8.01(b), (c), (d) or (f) (except, in the case of Section 8.01(c) or (d), with respect to fees as contemplated under this Section 2.19), shall in each case require the consent of such Defaulting Lender;

(i) all or any part of such LC Obligations shall be reallocated among the non-Defaulting Lenders in accordance with their respective Pro Rata Shares but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s LC Obligations does not exceed the total of all non-Defaulting Lenders’ Commitment Amounts, (y) the sum of each non-Defaulting Lender’s Revolving Credit Exposure plus the portion of such Defaulting Lender’s LC Obligations allocated to such non-Defaulting Lender does not exceed such non-Defaulting Lender’s Commitment Amount and (z) the conditions set forth in Section 3.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Administrative Agent (after giving effect to any partial reallocation pursuant to clause (i) above) cash collateralize such Defaulting Lender’s LC Obligations in accordance with the procedures set forth in Section 2.16.12 for so long as such LC Obligation is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Obligations pursuant to this Section 2.19(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.16.4 with respect to such Defaulting Lender’s LC Obligations during the period such Defaulting Lender’s LC Obligations are cash collateralized;

(iv) if the LC Obligations of the non-Defaulting Lenders are reallocated pursuant to this Section 2.19(c), then the fees payable to the Lenders pursuant to Section 2.16.4 shall be adjusted in accordance with such non-Defaulting Lenders’ Pro Rata Shares; and

(v) if any Defaulting Lender’s LC Obligations are neither cash collateralized nor reallocated pursuant to this Section 2.19(c), then, without prejudice to any rights or remedies of the LC Issuers or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Obligations) and letter of credit fees payable under Section 2.16.4 with respect to such Defaulting Lender’s LC Obligations shall be payable to the applicable LC Issuers until such LC Obligations are cash collateralized and/or reallocated; and

(d) so long as any Lender is a Defaulting Lender, no LC Issuer shall be required to issue, amend or increase any Facility LCs, unless it is satisfied that the related exposure and the Defaulting

THE AGENTS

SECTION 7.01 Authorization and Action. Each Lender hereby appoints and authorizes the Administrative Agent to take such action as administrative agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement (including enforcement or collection of the obligations of the Borrower hereunder), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders; provided that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement or applicable law. The Administrative Agent agrees to give to each Lender prompt notice of each notice given to it by the Borrower pursuant to the terms of this Agreement.

SECTION 7.02 Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their respective own gross negligence or willful misconduct. Without limiting the generality of the foregoing: (i) the Administrative Agent may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be

-46-

taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) the Administrative Agent makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (iii) the Administrative Agent shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or to inspect the property (including the books and records) of the Borrower; (iv) the Administrative Agent shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto; and (v) the Administrative Agent shall not incur any liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile) believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 7.03 Administrative Agent and Affiliates. With respect to its Commitment, Advances and other rights and obligations hereunder in its capacity as a Lender, JPMCB shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent; and the term “Lender” or “Lenders” shall include JPMCB in its individual capacity. JPMCB and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower, any Affiliate thereof and any Person who may do business with or own securities of the Borrower or any such Affiliate, all as if it were not Administrative Agent and without any duty to account therefor to the Lenders.

SECTION 7.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial statements referred to in Section 4.01(e) and such other 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 Administrative Agent 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.

SECTION 7.05 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrower), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Administrative Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any out-of-pocket expenses (including reasonable counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that such expenses are reimbursable by the Borrower but for which the Administrative Agent is not reimbursed by the Borrower.

SECTION 7.06 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment,

-47-

within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank described in clause (i) or (ii) of the definition of “Eligible Assignee” having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if no Event of Default or Unmatured Event of Default shall have occurred and be continuing, then no successor Administrative Agent shall be appointed under this Section 7.06 without the prior written consent of the Borrower, which consent shall not be unreasonably withheld or delayed.

The titles “Co-Documentation Agents,” “Co-Syndication Agents”, “Joint Active Lead Arrangers”, “Joint Passive Arrangers”, “Joint Active Bookrunners”, and “Joint Passive Bookrunners” (each, in such capacity or capacities, a “Titled Person”) are purely honorific, and no Person designated as a Titled Person shall have any duties or responsibilities in such capacity and no Titled Person shall have or be deemed to have any fiduciary relationship with any Lender or with the Borrower or any of its Affiliates.

SECTION 8.03 No Waiver; Remedies. No failure on the part of any Lender, any LC Issuer or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04 Costs and Expenses; Indemnification.

(a) The Borrower agrees to pay on demand all costs and expenses incurred by the Administrative Agent and the Joint Active Lead Arrangers in connection with the preparation, execution, delivery, administration, syndication, modification and amendment of this Agreement and the other documents to be delivered hereunder, including the reasonable fees, internal charges and out-of-pocket expenses of counsel (including in-house counsel) for the Administrative Agent and the Joint Active Lead Arrangers with respect thereto and with respect to advising the Administrative Agent and the Joint Active Lead Arrangers as to their respective rights and responsibilities under this Agreement. The Borrower further agrees to pay on demand all costs and expenses, if any (including counsel fees and expenses of outside counsel and of internal counsel), incurred by the Administrative Agent, any LC Issuer or any Lender in connection with the collection and enforcement (whether through negotiations, legal proceedings or otherwise) of the Borrower’s obligations under this Agreement and the other documents to be delivered by the Borrower hereunder, including reasonable counsel fees and expenses in connection with the enforcement of rights under this Section 8.04(a).

(b) If any payment of principal of, or any conversion of, any Eurodollar Advance is made other than on the last day of the Interest Period for such Advance, as a result of a payment or conversion pursuant to Section 2.09 or 2.12 or acceleration of the maturity of the Advances pursuant to Section 6.01 or for any other reason, the Borrower shall, upon demand by any Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amount required to compensate such Lender for any additional loss, cost or expense which it may reasonably incur as a result of such payment or conversion, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

(c) The Borrower agrees to indemnify and hold each Lender, each LC Issuer, each Agent and each of their respective Affiliates, officers, directors, advisors, agents and employees (each, an “Indemnified Person”) harmless from and against any claim, damage, loss, liability, cost or expense (including reasonable attorney’s fees and expenses, whether or not such Indemnified Person is named as a

-49-

party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) that any of them may pay or incur arising out of or relating to this Agreement or the transactions contemplated hereby, or the use by the Borrower or any Subsidiary of the proceeds of any Advance; provided that the Borrower shall not be liable for any portion of any such claim, damage, loss, liability, cost or expense resulting from such Indemnified Person’s gross negligence or willful misconduct as determined in a final non-appealable order of a court of competent jurisdiction. The Borrower’s obligations under this Section 8.04(c) shall survive the repayment of all amounts owing by the Borrower to the Lenders and the Administrative Agent under this Agreement and the termination of the Commitments and this Agreement. If and to the extent that the obligations of the Borrower under this Section 8.04(c) are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law. This Section 8.04(c) shall not apply with respect to Taxes other than any Taxes that represent losses or damages arising from any non-Tax claim. In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, any of the Borrower’s equityholders or creditors, an Indemnified Person or any other person or entity, whether or not an Indemnified Person is otherwise a party thereto.

SECTION 8.05 Right of Set-off. Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement, whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. Each Lender agrees to notify the Borrower promptly after any such set-off and application made by such Lender or Affiliate thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.05 are in addition to other rights and remedies (including other rights of set-off) that such Lender may have.

SECTION 8.06 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Borrower, the Agents and each Lender and their respective successors and assigns, provided that (except as permitted by Section 5.02(b)(iii)) the Borrower shall not have the right to assign rights hereunder or any interest herein without the prior written consent of all Lenders.

SECTION 8.07 Assignments and Participations.

(a) Each Lender may, with the prior written consent of the Borrower, each LC Issuer and the Administrative Agent (which consents shall not be unreasonably withheld or delayed), and if demanded by the Borrower pursuant to Section 8.07(g) shall to the extent required by such Section, assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it and its participation in Facility LCs); provided that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the Commitment Amount of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Assumption with respect to such assignment) shall in no event be less than $5,000,000 or, if less, the entire amount of such Lender’s Commitment, and shall be an integral multiple of $1,000,000 or such Lender’s entire Commitment, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Assumption, together with a

-50-

processing and recordation fee of $3,500 (which shall be payable by one or more of the parties to the Assignment and Assumption, and not by the Borrower (except in the case of a demand under Section 8.07(g)), and shall not be payable if the assignee is a Federal Reserve Bank), (v) the consent of the Borrower shall not be required after the occurrence and during the continuance of any Event of Default, and (vi) the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Assumption, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Assumption, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Assumption, relinquish its rights and be released from its obligations under this Agreement and, in the case of an Assignment and Assumption 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 (although an assigning Lender shall continue to be entitled to indemnification pursuant to Section 8.04(c)). Notwithstanding anything contained in this Section 8.07(a) to the contrary, (A) the consent of the Borrower and the Administrative Agent shall not be required with respect to any assignment by any Lender to an Affiliate of such Lender or to another Lender or to an Approved Fund, and (B) any Lender may at any time, without the consent of the Borrower, any LC Issuer or the Administrative Agent, and without any requirement to have an Assignment and Assumption executed, assign all or any part of its rights under this Agreement to a Federal Reserve Bank, provided that no such assignment shall release the transferor Lender from any of its obligations hereunder.

For the purposes of this Section 8.07(a), the term “Approved Fund” has the following meaning:

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

(b) By executing and delivering an Assignment and Assumption, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Assumption, 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 or any other instrument or document furnished pursuant hereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01(e) 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 Assumption; (iv) such assignee will, independently and without reliance upon the Administrative 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; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Administrative 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 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 of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

-51-

(c) The Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Assumption delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment Amount of, and principal amount of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of an Assignment and Assumption executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, the Administrative Agent shall, if such Assignment and Assumption has been completed and is in substantially the form of Exhibit A (including any necessary consents of the Administrative Agent, the LC Issuers and the Borrower), (i) accept such Assignment and Assumption, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

(e) Any Lender may, without the consent of the Borrower, any LC Issuer or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Advances owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged; (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations; and (C) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.01 that affects such Participant. Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.11, 2.14 and 8.04(b) (subject to the requirements and limitations therein, including the requirements under Section 2.14(f) (it being understood that the documentation required under Section 2.14(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 2.15 and 8.07(g) as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.11 or 2.14, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender, provided such Participant agrees to be subject to Section 2.15 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Advances or other obligations under this Agreement (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Advances or its other obligations hereunder) except to the extent that such disclosure is necessary to establish that such Commitment, Advance, or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

-52-

(f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, 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, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any confidential information relating to the Borrower received by it from such Lender (subject to customary exceptions regarding regulatory requirements, compliance with legal process and other requirements of law).

(g) If any Lender (i) shall make demand for payment under Section 2.11(a), 2.11(b) or 2.14, (ii) shall deliver any notice to the Administrative Agent pursuant to Section 2.12 resulting in the suspension of certain obligations of the Lenders with respect to Eurodollar Advances, (iii) does not consent to an amendment or waiver that requires the consent of all Lenders and has been approved by the Majority Lenders, or (iv) is a Defaulting Lender, then (A) in the case of clause (i), within 60 days after such demand (if, but only if, the payment demanded under Section 2.11(a), 2.11(b) or 2.14 has been made by the Borrower), (B) in the case of clause (ii), within 60 days after such notice (if such suspension is still in effect), (C) in the case of clause (iii), within 60 days after the date the Majority Lenders approve the applicable amendment or waiver, or (D) in the case of clause (v), at any time so long as such Lender continues to be a Defaulting Lender, as the case may be, the Borrower may demand that such Lender assign in accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrower and reasonably acceptable to the Administrative Agent and the LC Issuers all (but not less than all) of such Lender’s rights and obligations hereunder within the next succeeding 30 days; provided that such Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in LC Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts). If any such Eligible Assignee designated by the Borrower shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrower shall fail to designate any such Eligible Assignee for all of such Lender’s Commitment, Advances and participation in Facility LCs, then such Lender may (but shall not be required to) assign such Commitment and Advances to any other Eligible Assignee in accordance with this Section 8.07 during such period. No replacement of a Defaulting Lender pursuant to this Section 8.07(g) shall be deemed to be a waiver of any right that the Borrower, the Administrative Agent, any LC Issuer or any other Lender may have against such Defaulting Lender. In the event that a Lender assigns any Eurodollar Advances pursuant to this Section 8.07(g), such assignment shall be deemed to be a prepayment by the Borrower of such Eurodollar Advances for purposes of Section 8.04(b).

(h) If any LC Issuer does not consent to (A) a request by the Borrower to extend the Existing Termination Date pursuant to Section 2.17 or (B) a request by the Borrower to increase the Aggregate Commitment Amount pursuant to Section 2.18, the Borrower may upon written notice to the Administrative Agent and such LC Issuer, (i) reduce the LC Sublimit by an amount equal to such LC Issuer’s LC Pro Rata Share of the LC Sublimit and such LC Issuer shall cease to be an LC Issuer as of the date of such notice by the Borrower pursuant to this Section 8.07(h) (in which case the consent of such LC Issuer shall not be required under Section 2.17 or 2.18) or (ii) require such LC Issuer to assign and delegate its rights and obligations hereunder, as an LC Issuer and as a Lender in accordance with Section 8.07(g), and, in each case, the Borrower shall make arrangements satisfactory to such LC Issuer with respect to any Facility LCs previously issued by such LC Issuer.

(i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Bank”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Bank would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to

-53-

make any Advance, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Bank shall be obligated to make such Advance pursuant to the terms hereof.

What this means for the Borrower: When the Borrower opens an account, the Administrative Agent and the Lenders will ask for the Borrower’s name, tax identification number and business address and other information that will allow the Administrative Agent and the Lenders to identify the Borrower. The Administrative Agent and the Lenders may also ask to see the Borrower’s legal organizational documents or other identifying documents.

To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it may have against the Administrative Agent, the other Agents, the

SECTION 8.15 Conversion of Currencies.

(a) If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum owing hereunder in one currency into another currency, each party hereto agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures in the relevant jurisdiction the first currency could be purchased with such other currency on the Business Day immediately preceding the day on which final judgment is given.

(b) The obligations of the Borrower in respect of any sum due to any party hereto or any holder of the obligations owing hereunder (the “Applicable Creditor”) shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than the currency in which such sum is stated to be due hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable Creditor of any sum adjudged to be so due in the Judgment Currency, the Applicable Creditor may in accordance with normal banking procedures in the relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency so purchased is less than the sum originally due to the Applicable Creditor in the Agreement Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Applicable Creditor against such loss. The obligations of the Borrower contained in this Section 8.15 shall survive the termination of this Agreement and the payment of all other amounts owing hereunder.
