Each Borrowing shall be made pursuant to a Notice of Borrowing (or by telephone notice promptly confirmed in writing by a Notice of Borrowing), given not later than (i) 11:00 a.m. on the third Business Day before the date of the proposed Borrowing, in the case of a Eurodollar Rate Borrowing or (ii) 1:00 p.m. on the Business Day of the proposed Borrowing, in the case of a Reference Rate Borrowing, by the Borrower to the Administrative Agent, which shall in turn give to each Bank prompt notice of such proposed Borrowing by telecopier or telex. Each Notice of Borrowing shall be given by telecopier or telex, confirmed immediately in writing, or other written notice specifying the information required therein. In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, the Administrative Agent shall promptly notify each Bank of the applicable interest rate under Section 2.07(b). Each Bank shall, before 2:00 p.m. on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent’s Office in same day funds, such Bank’s Pro Rata Share of such Borrowing. After the Administrative Agent’s receipt of such funds and

-23-

upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent shall make such funds available to the Borrower at its account with the Administrative Agent.

          (b) Conversions and Continuations. The Borrower may elect to Convert or continue any Borrowing under this Section 2.02 by delivering an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office no later than (i) 11:00 a.m. on the date which is at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to or a continuation of a Borrowing comprised of Eurodollar Rate Advances and (ii) 1:00 p.m. on the Business Day of the proposed conversion date in the case of a Conversion to Borrowing comprised of Reference Rate Advance. Each such Notice of Conversion or Continuation shall be in writing or by telex or telecopier, confirmed immediately in writing, or other written notice specifying the information required therein. Promptly after receipt of a Notice of Conversion or Continuation under this Section, the Administrative Agent shall provide each Bank with a copy thereof and, in the case of a Conversion to or a Continuation of a Borrowing comprised of Eurodollar Rate Advances, notify each Bank of the applicable interest rate under Section 2.07(b). No such Conversion or continuation shall be deemed the making of a new Advance for purposes of this Agreement, including without limitation Article III.

          (c) Certain Limitations. Notwithstanding anything in paragraphs (a) and (b) above:

               (i) at no time shall there be more than six Interest Periods applicable to outstanding Eurodollar Rate Advances and the Borrower may not select Eurodollar Rate Advances for any Borrowing at any time that a Default has occurred and is continuing;

               (ii) if any Bank shall at least one Business Day before the date of any requested Borrowing, Conversion or continuation, 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 that any central bank or other Governmental Person asserts that it is unlawful, for such Bank or its Eurodollar Lending Office to perform its obligations under this Agreement to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances, the right of the Borrower to select Eurodollar Rate Advances from such Bank shall be suspended until such Bank shall notify the Administrative Agent that the circumstances causing such suspension no longer exist, and the Advance made by such Bank in respect of such Borrowing, Conversion or continuation shall be a Reference Rate Advance;

               (iii) if the Administrative Agent is unable to determine in good faith the Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance;

               (iv) if the Majority Banks shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to

-24-

such Banks of making or funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance; and

               (v) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and paragraph (b) above, the Administrative Agent shall so notify the Borrower and the Banks and such Advances shall be made available to the Borrower on the date of such Borrowing as Reference Rate Advances or, if an existing Advance, Converted into Reference Rate Advances.

          (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation, once delivered, shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Bank against any loss, out-of-pocket cost or expense incurred by such Bank as a result of any failure by the Borrower to fulfill on or before the date specified in such Notice of Borrowing, the applicable conditions set forth in Article III, including, without limitation, any loss (including any loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the Advance to be made by such Bank as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

          (e) Funding by Banks; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Bank prior to the proposed date of any Borrowing that such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available on such date in accordance with Section 2.02 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Bank has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Bank and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (a) in the case of a payment to be made by such Bank, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Reference Rate Advances. If the Borrower and such Bank shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Bank pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Bank’s Advance included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Bank that shall have failed to make such payment to the Administrative Agent. A notice of the

-25-

Administrative Agent to any Bank or the Borrower with respect to any amount owing under this subsection (e) shall be conclusive, absent manifest error.

          (f) Obligations of Banks Several. The obligations of the Banks hereunder to make Advances, to fund participations in Letters of Credit and to make payments pursuant to Section 9.04(c) are several and not joint. The failure of any Bank to make any Advance, to fund any such participation or to make any payment under Section 9.04(c) on any date required hereunder shall not relieve any other Bank of its corresponding obligation to do so on such date, and no Bank shall be responsible for the failure of any other Bank to so make its Advance, to purchase its participation or to make its payment under Section 9.04(c).

     Section 2.03. Reduction of the Commitments.

          (a) The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that (i) each partial reduction shall be in the aggregate amount of $1,000,000 or an integral multiple of $500,000 and (ii) the Borrower shall not terminate or reduce the aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the aggregate amount of Advances plus the Letter of Credit Exposure would exceed the aggregate Commitments.

          (b) Any reduction and termination of the Commitments pursuant to this Section 2.03 shall be applied ratably to each Bank’s Commitment and shall be permanent, with no obligation of the Banks to reinstate such Commitments and the commitment fees provided for in Section 2.06(a) shall thereafter be computed on the basis of the Commitments, as so reduced.

     Section 2.04. Prepayment of Advances.

          (a) Optional. The Borrower may prepay all Advances at any time, without premium or penalty, after giving by 12:00 p.m. (i) in the case of Eurodollar Rate Advances, at least three Business Days’ or (ii) in case of Reference Rate Advances, on the same Business Day, irrevocable prior written notice to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (a) any Borrowing comprised of Reference Rate Advances shall be made in an initial minimum aggregate principal amount of $500,000 and thereafter in $100,000 multiples and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a principal amount outstanding of at least $500,000 and (b) any Borrowing comprised of Eurodollar Rate Advances shall be made in an initial minimum aggregate principal amount of $1,000,000 and thereafter in $500,000 multiples and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a principal amount outstanding of at least $1,000,000. Full prepayments of any Borrowing are permitted without restriction of amounts. Each prepayment under this Section 2.04(a) shall be allocated between the Advances as determined by the Borrower.

-26-

          (b) Mandatory.

               (i) Reduction of Commitments. On the date of each reduction of the aggregate Commitments pursuant to Section 2.03 or if for any reason the outstanding amount of Advances plus the Letter of Credit Exposure exceeds the aggregate Commitments then in effect, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances and/or Cash Collateralize the Letter of Credit Obligations to the extent, if any, that the aggregate unpaid principal amount of all Advances plus the Letter of Credit Exposure exceeds the Commitments.

               (ii) Asset Disposition. If the Borrower or any of its Subsidiaries shall receive Net Cash Proceeds from any Asset Disposition in excess of $20,000,000 or any Recovery Event in excess of $20,000,000 (except (i) to the extent that a Reinvestment Notice shall be delivered in respect of such Asset Disposition or Recovery Event or (ii) with respect to cash receipts in the ordinary course of business of the applicable recipient), then on the date of receipt by the Borrower or the applicable Subsidiary of such Net Cash Proceeds, the Advances shall immediately be prepaid by an amount equal to the amount of such Net Cash Proceeds (except to the extent such Net Cash Proceeds are otherwise required by the Note Agreement to be applied to the ratable prepayment of the Note Obligations); provided, that, notwithstanding the foregoing, on each Reinvestment Prepayment Date the Advances shall be prepaid by an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event (except to the extent such Reinvestment Prepayment Amount is otherwise required by the Note Agreement to be applied to the ratable prepayment of the Note Obligations). For purposes of calculating whether the Net Cash Proceeds received from an Asset Disposition exceed $20,000,000 or from a Recovery Event exceed $20,000,000, such proceeds shall be determined as of the date of the applicable Asset Disposition or Recovery Event, whether or not received on such date, but no such amount shall be required to be applied to prepayment of the Advances pursuant to this Section until received by the applicable Person. The provisions of this Section do not constitute a consent to the consummation of any Disposition not permitted by Section 6.04.

               (iii) Debt Issuance. If any Debt for borrowed money shall be issued or incurred by the Borrower or any of its Subsidiaries (excluding any Debt incurred in accordance with Section 6.02), then on the date of such issuance or incurrence, the Advances shall be prepaid by an amount equal to the amount of the Net Cash Proceeds of such issuance or incurrence, except to the extent that such Net Cash Proceeds are otherwise required by the Note Agreement to be applied to the ratable prepayment of the Note Obligations. The provisions of this Section do not constitute a consent to the issuance or incurrence of any Debt by the Borrower or any of its Subsidiaries not otherwise permitted hereunder.

               (iv) Accrued Interest. Each prepayment under this Section 2.04(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment.

          (c) Illegality. If any Bank shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Person asserts that

-27-

it is unlawful for such Bank or its Eurodollar Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Bank then outstanding hereunder, (i) the Borrower shall (a) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Bank or (b) if required by such notice, on the second Business Day following its receipt of such notice prepay all of the Eurodollar Rate Advances made by such Bank then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date, (ii) such Bank shall simultaneously make a Reference Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Bank, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such Bank for any subsequent Borrowing shall be suspended until such Bank shall notify the Administrative Agent that the circumstances causing such suspension no longer exist; provided, that such Bank agrees to use reasonable efforts to designate a different Applicable Lending Office if the making of such designation would avoid such payment, and would not, in its reasonable judgment, be otherwise disadvantageous to such Bank.

          (d) No Additional Right; Ratable Prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.04, and all notices given pursuant to this Section 2.04 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.04 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     Section 2.05. Repayment of Advances. The Borrower shall repay the outstanding principal amount of the Advances outstanding on the Termination Date.

     Section 2.06. Fees.

          (a) Commitment Fees.

               (i) The Borrower agrees to pay to the Administrative Agent for the account of each Bank a commitment fee on the daily amount by which such Bank’s Commitment exceeds the sum of (a) such Bank’s outstanding Advances and (b) such Bank’s Pro Rata Share of the Letter of Credit Exposure, at the Applicable Margin for commitment fees from the date of this Agreement until the Termination Date. The commitment fees shall be due and payable quarterly in arrears on the last day of each March, June, September and December prior to the Termination Date and on the Termination Date.

          (b) Agent Fees. The Borrower agrees to pay to the Administrative Agent for the benefit of the Administrative Agent or the Lead Arranger, as applicable, the fees described in the letter dated as of February 8, 2005 from Bank of America and the Lead Arranger to the Borrower (the “Fee Letter”).

          (c) Letter of Credit Fees.

               (i) With respect to each Financial Letter of Credit issued hereunder, the Borrower agrees to pay to (a) the Administrative Agent for the pro rata benefit of the Banks a

-28-

fee per annum equal to the Applicable Margin for letter of credit fees on the aggregate amount available for drawing from time to time under such Financial Letter of Credit and (b) to the Issuing Bank a facing fee for each Letter of Credit of .125% per annum of the face amount of such Letter of Credit. Each such fee shall be payable quarterly in arrears on the last day of each March, June, September and December prior to the Termination Date and on the Termination Date (or, if later, the date on which all outstanding Letters of Credit have expired).

               (ii) With respect to each Performance Letter of Credit issued hereunder, the Borrower agrees to pay to (a) the Administrative Agent for the pro rata benefit of the Banks a one-time letter of credit fee in an amount equal to the Applicable Margin for letter of credit fees on the initial stated amount of such Performance Letter of Credit (or, with respect to any subsequent increase to the stated amount of any such Performance Letter of Credit, such increase in the stated amount) thereof, such fee to be payable on the date of such issuance, increase or extension and (b) to the Issuing Bank a facing fee for each Letter of Credit of .125% per annum of the face amount of such Letter of Credit, payable in advance, commencing on the date of issuance, increase or extension of such Letter of Credit and quarterly thereafter.

               (iii) The Borrower agrees to pay concurrently with each issuance, negotiation, drawing, or amendment of each Letter of Credit, to the Issuing Bank for the sole account of the Issuing Bank, issuance, negotiation, drawing and amendment fees and other standard costs and charges in the amounts set forth from time to time as the Issuing Bank’s published scheduled fees for such services.

     Section 2.07. Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Bank from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

          (a) Reference Rate Advances. If such Advance is a Reference Rate Advance, a rate per annum equal at all times to the Adjusted Reference Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable in arrears on the last day of each March, June, September and December and on the date such Reference Rate Advance shall be paid in full, provided that upon the occurrence and during the continuance of any Event of Default, such Advance shall bear interest at a rate per annum equal at all times to the Adjusted Reference Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum, payable on demand.

          (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of such Interest Period, and, in the case of six-month Interest Periods, on the day which occurs during such Interest Period three months from the first day of such Interest Period, provided that upon the occurrence and during the continuance of any Event of Default, such Advance shall bear interest at a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin plus 2.00% per annum, payable on demand.

-29-

          (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Bank, so long as any such Bank shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Bank, from the effective date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Bank shall be determined by such Bank and notified to the Borrower through the Administrative Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error).

          (d) Usury Recapture.

               (i) If, with respect to any Bank, the effective rate of interest contracted for under the Credit Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Credit Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Bank hereunder shall bear interest at a rate which would make the effective rate of interest for such Bank under the Credit Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “Lost Interest”) has been recaptured by such Bank.

               (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Bank pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Bank the interest rates charged under Section 2.07 hereunder shall be retroactively increased such that the effective rate of interest under the Credit Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Bank the amount of the Lost Interest remaining to be recaptured by such Bank.

               (iii) Notwithstanding the foregoing or any other term in this Agreement and the Credit Documents to the contrary, it is the intention of each Bank and the Borrower to conform strictly to any applicable usury laws. Accordingly, if any Bank contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Bank’s option be applied to the outstanding amount of the loans made hereunder by such Bank or be refunded to the Borrower.

     Section 2.08. Payments and Computations.

          (a) Payment Procedures. All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. The

-30-

Borrower shall make each payment under this Agreement and under the Notes not later than 2:00 p.m. on the day when due in Dollars to the Administrative Agent at the Administrative Agent’s Office in same day funds. The Administrative Agent shall promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent, the Issuing Bank or a specific Bank pursuant to Section 2.06(b), 2.06(c), 2.10, 2.11, 2.12, 2.13, or 9.04) in accordance with each Bank’s Pro Rata Share to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank or the Issuing Bank to such Bank for the account of its Applicable Lending Office, in each case to be allocated between the Types of Advances and applied in the manner determined by the Administrative Agent in its sole discretion.

          (b) Computations. All computations of interest based on the Reference Rate and of fees 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 computations of interest based on the Eurodollar Rate and the Federal Funds Rate 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 or fee shall be conclusive and binding for all purposes, absent manifest error.

          (c) Non-Business Day Payments. Whenever any payment 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 payment of interest or fees, as the case may be.

          (d) Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Banks or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Banks or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Banks or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Bank or the Issuing Bank, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. A notice of the Administrative Agent to any Bank or the Borrower with respect to any amount owing under this subsection (d) shall be conclusive, absent manifest error.

     Section 2.09. Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all the Banks, such Bank shall notify the Administrative Agent and forthwith purchase from the other Banks

-31-

such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share (according to the proportion of (a) the amount of the participation sold by such Bank to the purchasing Bank as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Bank’s ratable share (according to the proportion of (i) the amount of such Bank’s required repayment to the purchasing Bank to (ii) the total amount of all such required repayments to the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.09 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 Bank were the direct creditor of the Borrower in the amount of such participation.

     Section 2.10. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, whether as a result of any payment pursuant to Section 2.04, the acceleration of the maturity of the Notes pursuant to Article VII, or for any other reason or (b) the Borrower fails to make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by any Bank to the Borrower through the Administrative Agent (which demand shall provide a statement explaining the amount and setting forth the computation of any such loss or expense), pay to the Administrative Agent for the account of such Bank any amounts required to compensate such Bank for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Bank to fund or maintain such Advance.

     Section 2.11. Increased Costs.

          (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation occurring on or after the date of this Agreement or (ii) the compliance with any guideline or request from any central bank or other Governmental Person (whether or not having the force of law), there shall be any increase occurring on or after the date of this Agreement in the cost to any Bank of agreeing to make or making, funding or maintaining Eurodollar Rate Advances, then the Borrower shall from time-to-time, upon demand by such Bank (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost; provided, that, before making any such demand, such Bank agrees to promptly notify the Borrower and to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost and would not, in its reasonable judgment, be otherwise disadvantageous. A certificate as to the amount of

-32-

such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Bank shall be conclusive and binding for all purposes, absent manifest error.

          (b) Capital Adequacy. If any Bank or the Issuing Bank reasonably determines that its required compliance with any law or regulation or any guideline or request from any central bank or other Governmental Person (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Bank or the Issuing Bank or any corporation controlling such Bank or the Issuing Bank and that the amount of the capital is increased by or based upon the existence of such Bank’s commitment to lend or the Issuing Bank’s commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days’ prior written notice by such Bank or the Issuing Bank (with a copy of any such demand to the Administrative Agent), the Borrower shall immediately pay to the Administrative Agent for the account of such Bank or the Issuing Bank, as the case may be, from time-to-time as specified by such Bank or the Issuing Bank, additional amounts sufficient to compensate such Bank or the Issuing Bank, in light of the circumstances, to the extent that such Bank or the Issuing Bank, as the case may be, reasonably determines the increase in capital to be allocable to the existence of such Bank’s commitment to lend or the Issuing Bank’s commitment to issue the Letters of Credit under this Agreement. A certificate as to the amounts showing in reasonable detail the calculation of the amounts submitted to the Borrower by such Bank or the Issuing Bank shall be presumptively correct, absent manifest error.

          (c) Letters of Credit. If any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Person charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, the Issuing Bank or (ii) impose on the Issuing Bank any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to the Issuing Bank of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Bank’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Bank, the Borrower shall pay to the Administrative Agent for the account of the Issuing Bank, from time to time as specified by the Issuing Bank, additional amounts which shall be sufficient to compensate the Issuing Bank for such increased cost. A certificate as to such increased cost incurred by the Issuing Bank, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by the Issuing Bank to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.12. Taxes.

          (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.08, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank, the Issuing Bank and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction (any political subdivision of the jurisdiction) under the laws of which such Bank, the

-33-

Issuing Bank or the Administrative Agent (as the case may be) is organized or maintains its Applicable Lending Office (all such income and franchise taxes collectively referred to as “Excluded Taxes”, and all such taxes, levies, imposts, deductions, charges, withholdings and liabilities, other than the Excluded Taxes being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Bank, the Issuing Bank or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12), such Bank, the Issuing Bank or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Credit Documents (hereinafter referred to as “Other Taxes”).

          (b) Indemnification. The Borrower hereby indemnifies each Bank, the Issuing Bank and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.12) paid by such Bank, the Issuing Bank or the Administrative Agent, as the case may be, and any liability arising therefrom or with respect thereto. Each payment required to be made by the Borrower in respect of this indemnification shall be made to the Administrative Agent for the benefit of any party claiming such indemnification within 30 days from the date the Borrower receives written demand therefor from the Administrative Agent on behalf of itself as Administrative Agent, the Issuing Bank or any such Bank.

          (c) Evidence of Tax Payments. Within 30 days after the date of any payment of Taxes or Other Taxes, the Borrower will furnish to the Administrative Agent upon request thereby, at its address referred to in Section 9.02, the original or a certified copy of a receipt evidencing payment thereof. If no Taxes or Other Taxes are payable in respect of any payment hereunder, the Borrower will furnish to the Administrative Agent, at such address, a certificate from each appropriate taxing authority, or an opinion of counsel acceptable to the Administrative Agent, in either case stating that such payment is exempt from or not subject to Taxes; provided, however, that such certificate or opinion need only be given if (i) the Borrower makes any payment from an account located outside the United States or (ii) the payment is made by a payor that is not a United States Person. For purposes of this Section 2.12 the terms “United States” and “United States Person” shall have the respective meanings set forth in Section 7701 of the Code.

          (d) Survival. Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.12 shall survive the payment in full of principal and interest hereunder.

-34-

          (e) Foreign Bank Withholding Exemption. Each Bank and Issuing Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it shall deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as a condition to, the effectiveness of any Assignment and Assumption (i) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case may be, certifying in each case that such Bank is entitled to receive payments under this Agreement and the Notes payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding tax, and (iii) any other governmental forms which are necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax, which have been reasonably requested by the Borrower. Each Bank which delivers to the Borrower and the Administrative Agent a Form W-8BEN or W-8ECI and Form W-8 or W-9 pursuant to the next preceding sentence further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said letter and Form W-8BEN or W-8ECI and Form W-8 or W-9, or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such letter or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent letter and form previously delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in the case of a Form W-8BEN or W-8ECI that such Bank is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Bank from duly completing and delivering any such letter or form with respect to it and such Bank advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax, such Bank shall not be required to deliver such letter or forms. The Borrower shall withhold tax at the rate and in the manner required by the laws of the United States with respect to payments made to a Bank failing to timely provide the requisite Internal Revenue Service forms.

          (f) Change of Applicable Lending Office. Any Bank claiming any additional amount payable pursuant to this Section 2.12 shall use its reasonable best efforts (consistent with its internal policy and applicable Governmental Rules) to change the jurisdiction of its lending office if such a change would avoid the need for, or reduce the amount of, any such additional amount that may thereafter accrue and would not, in the reasonable judgment of such Bank, be materially disadvantageous to such Bank.

          (g) Repayment under Certain Circumstances. Each Bank (and the Administrative Agent with respect to payments to the Administrative Agent for its own account) will (i) take all reasonable actions by all usual means to maintain an exemption, if any, available to it from United States tax withholding (whether available by treaty, by existing administrative waiver or by virtue of the location of such Bank’s lending office) and (ii) otherwise cooperate with the Borrower to minimize amounts payable by the Borrower under this Section 2.12;

-35-

provided, however, that neither any Bank nor the Administrative Agent shall be obligated by reason of this Section 2.12(g) to contest the payment of any Taxes or Other Taxes, to disclose any information regarding its tax affairs or tax computations or to reorder its tax or other affairs. Subject to the foregoing, to the extent that the Borrower pays any amount pursuant to this Section 2.12 and such Bank or the Administrative Agent receives a refund of any or all of such amount, such refund shall be applied to reduce any amounts then due and owing under this Agreement or, to the extent that no amounts are then due and owing under this Agreement, paid over to the Borrower.

          (h) Exclusions. Notwithstanding anything contained herein to the contrary, the Borrower shall not be required to make any payment to any Bank under this Section 2.12 with respect to any Taxes or Other Taxes that (i) are attributable to such Bank’s failure to comply with the requirements of this Section 2.12, (ii) are United States taxes imposed on amounts payable to such Bank at the time the Bank became a party to this Agreement or (iii) are United States taxes imposed as a result of an event occurring after the date on which such Bank became a Bank, other than a change in any applicable Governmental Rule.

     Section 2.13. Letters of Credit.

          (a) Commitment.

               (i) The parties hereto acknowledge that on and after the Effective Date the Existing Letters of Credit shall be Letters of Credit issued by the Issuing Bank pursuant to this Agreement. From time to time from the Effective Date until the Termination Date, at the request of the Borrower, the Issuing Bank shall, in reliance upon the agreements of the Banks set forth in this Section 2.13 on the terms and conditions hereinafter set forth, issue, increase, or extend the expiration date of Letters of Credit for the account of the Borrower or any Subsidiary on any Business Day; provided however, that for any Letter of Credit issued for the account of any Subsidiary, the Borrower will be joint and severally liable for the reimbursement obligations of such Subsidiary under such Letter of Credit as provided in subsection (h) below.

               (ii) No Letter of Credit shall be issued, increased, or extended:

                    (A) unless such issuance, increase, or extension would not cause the Letter of Credit Exposure to exceed the aggregate Commitments less the aggregate outstanding principal amount of all Advances;

                    (B) unless such Letter of Credit has an Expiration Date not later than the earlier of (a) 24 months after the date of issuance thereof and (b) March 31, 2011;

                    (C) unless such Letter of Credit Documents are in form and substance reasonably acceptable to the Issuing Bank in its sole discretion;

                    (D) unless such Letter of Credit is either a Performance Letter of Credit or a Financial Letter of Credit; and

                    (E) unless the Borrower has delivered to the Issuing Bank a completed and executed Letter of Credit Application

-36-

               (iii) The Issuing Bank shall not be under any obligation to issue any Letter of Credit:

                    (A) if any order, judgment or decree of any Governmental Person or arbitrator shall by its terms purport to enjoin or restrain the Issuing Bank from issuing such Letter of Credit, or any Law applicable to the Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Person with jurisdiction over the Issuing Bank shall prohibit, or request that the Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Bank is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon the Issuing Bank any unreimbursed loss, cost or expense which was not applicable on the Effective Date and which the Issuing Bank in good faith deems material to it;

                    (B) if the issuance of such Letter of Credit would violate one or more policies of the Issuing Bank; and

                    (C) if a default of any Bank’s obligations to fund under Section 2.13(c) exists or any Bank is at such time a Default Lender hereunder, unless the Issuing Bank has entered into satisfactory arrangements with the Borrower or such Bank to eliminate the Issuing Bank’s risk with respect to such Bank.

          (b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of Credit.

               (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to the Issuing Bank (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of the Borrower. Such Letter of Credit Application must be received by the Issuing Bank and the Administrative Agent not later than 1:00 p.m. at least two Business Days (or such later date and time as the Administrative Agent and the Issuing Bank may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the Issuing Bank: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the Issuing Bank may reasonably require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the Issuing Bank (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the Issuing Bank may reasonably require. Additionally, the Borrower shall furnish to the Issuing Bank and the Administrative Agent such other documents and information pertaining to such

-37-

requested Letter of Credit issuance or amendment, including any Letter of Credit Documents, as the Issuing Bank or the Administrative Agent may reasonably require.

               (ii) Promptly after receipt of any Letter of Credit Application, the Issuing Bank will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the Issuing Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has received written notice from any Bank, the Administrative Agent, or the Borrower, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Article III shall not then be satisfied, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the requested date, issue a Letter of Credit for the account of the Borrower (or the applicable Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance with the Issuing Bank’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank a risk participation in such Letter of Credit in an amount equal to the product of such Bank’s Pro Rata Share times the amount of such Letter of Credit.

               (iii) If the Borrower so requests in any applicable Letter of Credit Application, the Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the Issuing Bank to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the Issuing Bank, the Borrower shall not be required to make a specific request to the Issuing Bank for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Banks shall be deemed to have authorized (but may not require) the Issuing Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than March 31, 2011; provided, however, that the Issuing Bank shall not permit any such extension if (A) the Issuing Bank has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section 2.13(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date (1) from the Administrative Agent that the Majority Banks have elected not to permit such extension or (2) from the Administrative Agent, any Bank or the Borrower that one or more of the applicable conditions specified in Section 3.02 is not then satisfied, and in each such case directing the Issuing Bank not to permit such extension.

               (iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the Issuing Bank will also deliver to the Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

-38-

               (v) All references in this Section 2.13 to times of day shall be references to (A) Eastern time (daylight or standard, as applicable) if Bank of America is the applicable Issuing Bank or (B) Pacific time (daylight or standard, as applicable) if UBOC is the applicable Issuing Bank.

          (c) Drawings and Reimbursements, Funding of Participations.

               (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the Issuing Bank shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m. on the date of any payment by the Issuing Bank under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse the Issuing Bank through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the Issuing Bank by such time, the Administrative Agent shall promptly notify each Bank of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Bank’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested a Borrowing of Reference Rate Advances to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.01 for the principal amount of Reference Rate Advances, but subject to the amount of the unutilized portion of the aggregate Commitments and the conditions set forth in Section 3.02 (other than the delivery of a Notice of Borrowing). Any notice given by the Issuing Bank or the Administrative Agent pursuant to this Section 2.13(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

               (ii) Each Bank shall upon any notice pursuant to Section 2.13(c)(i) make funds available to the Administrative Agent for the account of the Issuing Bank at the Administrative Agent’s Office in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.13(c)(iii), each Bank that so makes funds available shall be deemed to have made a Reference Rate Advance to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Issuing Bank.

               (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of Reference Rate Advances because the conditions set forth in Section 3.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the Issuing Bank an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Adjusted Reference Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum. In such event, each Bank’s payment to the Administrative Agent for the account of the Issuing Bank pursuant to Section 2.13(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Bank in satisfaction of its participation obligation under this Section 2.13.

               (iv) Until each Bank funds its Advance or L/C Advance pursuant to this Section 2.13(c) to reimburse the Issuing Bank for any amount drawn under any Letter of

-39-

Credit, interest in respect of such Bank’s Pro Rata Share of such amount shall be solely for the account of the Issuing Bank.

               (v) Each Bank’s obligation to make Advances or L/C Advances to reimburse the Issuing Bank for amounts drawn under Letters of Credit, as contemplated by this Section 2.13(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Bank may have against the Issuing Bank, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such making of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the Issuing Bank for the amount of any payment made by the Issuing Bank under any Letter of Credit, together with interest as provided herein.

               (vi) If any Bank fails to make available to the Administrative Agent for the account of the Issuing Bank any amount required to be paid by such Bank pursuant to the foregoing provisions of this Section 2.13(c) by the time specified in Section 2.13(c)(ii), the Issuing Bank shall be entitled to recover from such Bank (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Issuing Bank at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Issuing Bank in accordance with banking industry rules on interbank compensation. A certificate of the Issuing Bank submitted to any Bank (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

          (d) Repayment of Participations.

               (i) At any time after the Issuing Bank has made a payment under any Letter of Credit and has received from any Bank such Bank’s L/C Advance in respect of such payment in accordance with Section 2.13(c), if the Administrative Agent receives for the account of the Issuing Bank any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Bank its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Bank’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

               (ii) If any payment received by the Administrative Agent for the account of the Issuing Bank pursuant to Section 2.13(c)(i) is required to be returned under any of the circumstances described in Section 9.10 (including pursuant to any settlement entered into by the Issuing Bank in its discretion), each Bank shall pay to the Administrative Agent for the account of the Issuing Bank its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Bank, at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Banks under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

-40-

          (e) Obligations Absolute. The obligation of the Borrower to reimburse the Issuing Bank for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

               (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Credit Document;

               (ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

               (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

               (iv) any payment by the Issuing Bank under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the Issuing Bank under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

               (v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or any Subsidiary.

     The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the Issuing Bank. To the extent permitted by applicable law, the Borrower shall be conclusively deemed to have waived any such claim against the Issuing Bank and its correspondents unless such notice is given as aforesaid.

          (f) Role of Issuing Bank. Each Bank and the Borrower agree that, in paying any drawing under a Letter of Credit, the Issuing Bank shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the Issuing Bank, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the Issuing Bank shall be liable to any Bank for (i) any action taken or

-41-

omitted in connection herewith at the request or with the approval of the Banks or the Majority Banks, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Issuing Bank, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the Issuing Bank shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.13(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the Issuing Bank, and the Issuing Bank may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower directly, or indirectly by a Subsidiary, which the Borrower proves were caused by the Issuing Bank’s willful misconduct or gross negligence or the Issuing Bank’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the Issuing Bank shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

          (g) Cash Collateral. Upon the request of the Administrative Agent, if, as of 5 days prior to the Termination Date, any Letter of Credit Obligation for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then outstanding amount of all Letter of Credit Obligations. Sections 2.04(b), 7.02 and 7.03 set forth certain additional requirements to deliver Cash Collateral hereunder. For purposes of this Section 2.13, Sections 2.04, 7.02 and 7.03, “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the Issuing Bank and the Banks, as collateral for the Letter of Credit Obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory to the Administrative Agent and the Issuing Bank (which documents are hereby consented to by the Banks). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Banks, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America. Notwithstanding anything herein to the contrary, provided that the Borrower has Cash Collateralized the then outstanding amount of all Letter of Credit Obligations with respect to each Letter of Credit with an expiration date after the Termination Date in accordance with this Section 2.15(g), each Bank’s participation in the Letter of Credit Obligations shall be released as of the Termination Date.

          (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the Issuing Bank and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby

-42-

Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to each commercial Letter of Credit.

          (i) Conflict with Letter of Credit Documents. In the event of any conflict between the terms hereof and the terms of any Letter of Credit Document, the terms hereof shall control.

          (j) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary, the Borrower shall be obligated to reimburse the Issuing Bank hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

     Section 2.14. Replacement of Banks. If any Bank requests compensation under Section 2.11, or if the Borrower is required to pay any additional amount to any Bank or any Governmental Person for the account of any Bank pursuant to Section 2.12, or if any Bank is a Defaulting Bank or a Non-Consenting Bank (as defined below in this Section 2.14), then the Borrower may, at its sole expense and effort, upon notice to such Bank and the Administrative Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.06), all of its interests, rights and obligations under this Agreement and the related Credit Documents to an assignee that shall assume such obligations (which assignee may be another Bank, if a Bank accepts such assignment), provided that:

          (a) the Assignee shall have paid to the Administrative Agent the assignment fee specified in Section 9.06(a);

          (b) such Bank shall have received payment of an amount equal to the outstanding principal of its Advances and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.11 and 2.12) 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);

          (c) in the case of any such assignment resulting from a claim for compensation under Section 2.11 or payments required to be made pursuant to Section 2.12, such assignment will result in a reduction in such compensation or payments thereafter; and

          (d) such assignment does not conflict with applicable Governmental Rules.

     A Bank shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. In the event that (i) the Borrower or the Administrative Agent requests that the Banks consent to a waiver of any provision of the Credit Documents or agree to any amendment thereto, (ii) such consent or amendment requires the agreement of all of the Banks in accordance with the terms of Section 9.01 and (iii) at least the

-43-

Majority Banks have agreed to such consent or amendment, then any Bank that does not agree to such consent or amendment shall be a “Non-Consenting Bank”.

The indemnities provided in this section shall survive the repayment or any other satisfaction of the Obligations of the Borrower under the Credit Documents.

     Section 5.13. Use of Proceeds.

Each of the Banks and the Issuing Bank hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent and Collateral Agent hereunder and under the other Credit Documents and authorizes the Agents to take such actions on its behalf and to exercise such powers as are delegated to the Agents by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agents, the Banks and the Issuing Bank, and neither the Borrower nor any other Guarantor shall have rights as a third party beneficiary of any of such provisions.

     Section 8.02. Rights as a Bank. The Person serving as the Agents hereunder shall have the same rights and powers in its capacity as a Bank as any other Bank and may exercise the same as though it were not an Agent and the term “Bank” or “Banks” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agents hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not an Agent hereunder and without any duty to account therefor to the Banks.

     Section 8.03. Exculpatory Provisions. The Agents shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, the Agents:

          (a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

          (b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that such Agent is required to exercise as directed in writing by the Majority Banks (or such other number or percentage of the Banks as shall be expressly provided for herein or in the other Credit Documents), provided that the Agents shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Credit Document or applicable law; and

          (c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

-70-

     The Agents shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Banks (or such other number or percentage of the Banks as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.01 and 7.02) or (ii) in the absence of its own gross negligence or willful misconduct. The Agents shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Agent by the Borrower, a Bank or the Issuing Bank.

     The Agents shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

     Section 8.04. Reliance by Agents. The Agents shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agents also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of an Advance, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Bank or the Issuing Bank, the Agents may presume that such condition is satisfactory to such Bank or the Issuing Bank unless the Agent shall have received notice to the contrary from such Bank or the Issuing Bank prior to the making of such Advance or the issuance of such Letter of Credit. The Agents may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

     Section 8.05. Delegation of Duties. The Agents may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Agent. The Agents and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties.

-71-

States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Majority Banks and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Banks and the Issuing Bank, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Banks that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Banks or the Issuing Bank under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Bank and the Issuing Bank directly, until such time as the Majority Banks appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article and Section 9.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

     Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuing Bank and Collateral Agent.

     Section 8.07. Non-Reliance on Agents and Other Banks. Each Bank and the Issuing Bank acknowledges that it has, independently and without reliance upon the Agents or any other Bank or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Agents or any other Bank or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its

     Section 8.09. Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any Guarantor, the Administrative Agent (irrespective of whether the principal of any Advance or Letter of Credit Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

          (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Advances, Letter of Credit Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Banks, the Issuing Bank and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Banks, the Issuing Bank and the Administrative Agent and their respective agents and counsel and all other amounts due the Banks, the Issuing Bank and the Administrative Agent under Sections 2.13, 2.06 and 9.04) allowed in such judicial proceeding; and

     Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Bank or the Issuing Bank any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Bank or to authorize the Administrative Agent to vote in respect of the claim of any Bank in any such proceeding.

     Section 8.10. Collateral and Guaranty Matters. The Banks and the Issuing Bank irrevocably authorize the Collateral Agent, at its option and in its discretion,

          (a) to release any Lien on any property granted to or held by the Collateral Agent under any Credit Document (i) upon termination of the aggregate Commitments and

          (b) to subordinate any Lien on any property granted to or held by the Administrative Agent under any Credit Document to the holder of any Lien on such property that is permitted by Section 6.01; and

          (c) to release any Guarantor from its obligations under the Guaranty and any other applicable Credit Document if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

     Upon request by the Administrative Agent at any time, the Majority Banks will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty or any other Credit Document pursuant to this Section 8.10.

     Section 8.11. Swap Agreements. The benefit of the Security Documents and of the provisions of this Agreement relating to any collateral securing the Obligations shall also extend to and be available to those Banks or their Affiliates which are counterparties to any Interest Rate Contract or Hydrocarbon Hedge Agreement with the Borrower or any of its Subsidiaries on a pro rata basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise under any such Interest Rate Contract or Hydrocarbon Hedge Agreement that is in effect while such Person or its Affiliate is a Bank, but only while such Person or its Affiliate is a Bank, including any Interest Rate Contracts and Hydrocarbon Hedge Agreements between such Persons in existence prior to the Effective Date.

the transactions contemplated hereby or thereby, (ii) any Advance or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower or any other Guarantor, and regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower or any other Subsidiary against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Credit Document, if the Borrower or such Subsidiary has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

          (c) Reimbursement by Banks. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by it to the Administrative Agent (or any sub-agent thereof), the Issuing Bank or any Related Party of any of the foregoing, each Bank severally agrees to pay to the Administrative Agent (or any such sub-agent), the Issuing Bank or such Related Party, as the case may be, such Bank’s Pro Rata Share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or the Issuing Bank in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent) or Issuing Bank in connection with such capacity. The obligations of the Banks under this subsection (c) are subject to the provisions of Section 2.02(f).

          (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Credit Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Advance or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Credit Documents or the transactions contemplated hereby or thereby.

-77-

          (e) Payments. All amounts due under this Section shall be payable not later than ten Business Days after demand therefor.

          (f) Survival. The agreements in this Section shall survive the resignation of the Administrative Agent (and the Issuing Bank), the replacement of any Bank, the termination of the aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

     Section 9.05. Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower, the Administrative Agent and the Banks and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, the Issuing Bank and each Bank and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights or delegate its duties under this Agreement or any interest in this Agreement without the prior written consent of each Bank.

     Section 9.06. Bank Assignments and Participations.

          (a) Assignments. Any Bank may assign to one or more banks or other entities all or any portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it, and the participation interest in the Letter of Credit Obligations held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of such Bank’s rights and obligations assigned under this Agreement (including, without limitation, its obligations to make Advances), (ii) the amount of the Commitments and Advances of such Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Assumption with respect to such assignment) shall be, if to an entity other than a Bank, not less than $5,000,000.00 and shall be an integral multiple of $1,000,000.00, (iii) each such assignment shall be to an Affiliate, an Approved Fund or 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 the Notes (if any) subject to such assignment, and (v) each Eligible Assignee (other than the Eligible Assignee of the Administrative Agent) shall pay to the Administrative Agent a $3,500 administrative fee. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Assumption, which effective date shall be at least three Business Days after the execution thereof (unless waived by the Administrative Agent), (a) the assignee thereunder shall be a party hereto for all purposes 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 Bank hereunder and (b) such Bank 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 such Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto).

          (b) Term of Assignments. By executing and delivering an Assignment and Assumption, the Bank 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

-78-

Assumption, such Bank 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 of value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the Guarantors or the performance or observance by the Borrower or the Guarantors of any of their 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 4.05 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 Bank or any other Bank 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 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 (vi) 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 Bank.

          (c) The Register. The Administrative Agent shall maintain at its address referred to in Section 9.02 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 Banks and the Commitments of, and principal amount of the Advances owing to, each Bank 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, the Issuing Bank, and the Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice.

          (d) Procedures. Upon its receipt of an Assignment and Assumption executed by a Bank and an Eligible Assignee, together with the Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Assumption has been completed and is in substantially the form of the attached Exhibit D, (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) Participations. Each Bank may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it, its participation interest in the Letter of Credit Obligations, and the Notes held by it); provided, however, that (i) such Bank’s obligations under this Agreement (including, without limitation, its Commitments to the Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall remain the holder of any such Notes for all purposes of this Agreement, (iv) the

-79-

Borrower, the Administrative Agent, and the Issuing Bank and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement, and (v) such Bank shall not require the participant’s consent to any matter under this Agreement, except for change in the principal amount of the Notes, reductions in fees or interest (in each case to the extent subject to such participation), releasing all or substantially all of the Collateral (other than pursuant to Section 9.18), or extending the Termination Date (provided that, in any case in which a participant has the right to approve any amendment, waiver or consent as described above in this clause (v), such Bank shall retain (and hereby agrees to exercise) the right to repurchase the participation of such participant if such participant does not approve any such amendment, waiver or consent). The Borrower hereby agrees that participants shall have the same rights under Sections 2.10, 2.11, 2.12(b) and 9.04 as a Bank to the extent of their respective participations.

     Section 9.07. Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Banks and the Issuing Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, any Bank, the Issuing Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower.

     For purposes of this Section, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Bank or the Issuing Bank on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary, provided that, in the case of information received from the Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

     Section 9.08. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which

-80-

when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

     Section 9.09. Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Credit Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Bank, regardless of any investigation made by the Administrative Agent or any Bank or on their behalf and notwithstanding that the Administrative Agent or any Bank may have had notice or knowledge of any Default at the time of any Advance or issuance of Letter of Credit, and shall continue in full force and effect as long as any Advance or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

     Section 9.10. Severability. In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

     Section 9.11. Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the Administrative Agent, the Issuing Bank or any Bank, or the Administrative Agent, the Issuing Bank or any Bank exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, the Issuing Bank or such Bank in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Bank and the Issuing Bank severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Banks and the Issuing Bank under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement

     Section 9.12. Guaranties. The Administrative Agent and each of the Banks hereby consent to the terms and conditions of the Amended and Restated Subsidiary Guaranties executed by each of the Guarantors on the date hereof.

     Section 9.13. Usury Not Intended. It is the intent of the Borrower, the Administrative Agent and the Banks in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of the Banks including such applicable laws of the State of Texas and the United States of America from time-to-time in effect. In furtherance thereof, the Administrative Agent, the Banks and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to

-81-

create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement and the other Credit Documents; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and the Bank receiving same shall credit the same on the principal of its Advances (or if its Advances shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Obligations is accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the Advances (or, if the Advances shall have been paid in full, refunded to the Borrower of such interest). The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith. In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower, the Administrative Agent and the Banks shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Advances, all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations.

     Section 9.14. Waiver of Jury; Consent to Jurisdiction. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any legal proceeding directly or indirectly arising out of or relating to this agreement or any other Credit Document or the transactions contemplated hereby or thereby (whether based on contract, tort or any other theory). Each party hereto (a) certifies that no representative, agent or attorney of any other person has represented, expressly or otherwise, that such other person would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this agreement and the other Credit Documents by, among other things, the mutual waivers and certifications in this section. Each such Party hereby irrevocably submits to the nonexclusive jurisdiction of the United States district court for the northern district of Texas and of any Texas state court sitting in Dallas, Texas for purposes of all legal proceedings arising out of or relating to this Agreement, the other Credit Documents, and the transactions contemplated thereby.

     Section 9.15. Governing Law. This Agreement, the Notes and the other Credit Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 15, Subtitle 3, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loans and revolving tri-party accounts), shall not apply to this Agreement, the Notes,

-82-

or the transactions contemplated hereby and (b) to the extent that any Bank may be subject to Texas law limiting the amount of interest payable for its account, such Bank shall utilize the indicated (weekly) rate ceiling from time to time in effect as provided in Chapter 303 of the Texas Finance Code, as amended (formerly known as the indicated (weekly) rate ceiling in Article 5069-1.04 of the Revised Civil Statutes of Texas).

     Section 9.16. Credit Documents. To the extent the specific terms and provisions of this Credit Agreement expressly conflict with the specific terms and provisions of any of the other Credit Documents, the specific terms and provisions of this Credit Agreement shall control.

     Section 9.17. Existing Indebtedness. The indebtedness of the Borrower evidenced under this Agreement and the other Credit Documents is given in renewal, extension, modification but not in extinguishment or discharge of, a portion of the indebtedness evidenced by the Notes executed by the Predecessor Borrower each dated June 18, 2004, in the aggregate principal amount of $200,000,000 executed by the Predecessor Borrower to the order of the lenders named therein, each bearing interest and being due and payable as therein provided.

     Section 9.18. Release of Collateral. If after the Effective Date (a) the Borrower has senior unsecured long-term debt outstanding (or if no such senior unsecured long-term debt is outstanding that is rated by S&P or Moody’s, the Borrower has a corporate debt rating) that (i) is rated by S&P and all such debt is rated at or above BB+ by S&P and such rating shall be the only rating of the Borrower with respect to such debt; (ii) is rated by Moody’s and all such debt is rated at or above Ba1 by Moody’s and such rating shall be the only rating of the Borrower with respect to such debt; or (iii) is rated by S&P and Moody’s and all such debt is rated at or above BB+ by S&P and Ba1 by Moody’s (a “Ratings Increase”), and (b) so long as no Default or Event of Default shall have occurred and then be continuing at such time, then the Collateral shall be released from the Liens created by the Security Documents and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent, the Borrower and each Guarantor thereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the Borrower and its respective Subsidiaries; provided however, that (A) the Holders shall also grant a similar release of Collateral, (B) the Borrower and its Subsidiaries shall grant the Administrative Agent and the Banks a negative pledge on the assets of the Borrower and its Subsidiaries, except for Liens permitted by Section 6.02, and shall not grant a negative pledge to any other creditor other than the Holders and (C) the obligations of the Borrower arising under this Agreement and the Credit Documents rank pari passu and equal in right of payment with all of the other Debt of the Borrower, which is not by its terms secured by any assets of the Borrower and its Subsidiaries, and which is not subordinate in right of payment to any other Debt of the Borrower or its Subsidiaries. At the request and expense of the Borrower following any such termination and release, the Collateral Agent shall deliver to the Borrower or such respective Subsidiary any Collateral held by the Collateral Agent under the Security Documents, and shall execute and deliver to the Borrower or such Subsidiary such documents as such Person shall reasonably request to evidence such termination and release. Notwithstanding the foregoing, if subsequent to such Rating Increase, the Borrower has senior unsecured long-term debt outstanding that (i) is rated by Standard & Poor’s and all such debt is rated below BB+ by S&P and such rating shall be the only rating of the Borrower; (ii) is rated by Moody’s and all such debt is rated below Ba1 by Moody’s and such rating shall be the only rating of the Borrower; or (iii) is rated by S&P and

-83-

Moody’s and all such debt is rated below BB+ by Standard & Poor’s and Ba1 by Moody’s, then, at the expense of the Borrower, the Borrower shall promptly, or such cause each of its Subsidiaries to promptly, execute and deliver to the Collateral Agent such security agreements, amendments to this Agreement, other documents and legal opinions, as the Collateral Agent and the Lenders may reasonably request or deem necessary in connection with the foregoing grant of a security interest, in order to cause the Collateral to be subject to the Liens created by the Security Documents as of the Effective Date, and the Company shall execute and deliver such security agreements, amendments to this Agreement, other documents and legal opinions, as the Agent and the Lenders may reasonably request in connection with the foregoing grant of a security interest, and the provisions of this Section 9.18 shall not apply to any future Ratings Increase.

     Section 9.19. Assignment and Assumption. Effective as of the Effective Date, the Predecessor Borrower assigns and transfers all its rights, title, interest, liabilities and obligations to the Borrower under the Existing Credit Agreement as if the Borrower had originally executed the Credit Agreement. The Borrower hereby expressly assumes the obligations of the Predecessor Borrower under the Existing Credit Agreement and each of the other Credit Documents to which the Predecessor Borrower was a party. The Borrower hereby agrees to be bound by the terms of the Agreement and to perform all of the obligations of the Predecessor Borrower in respect thereof as if the Existing Credit Agreement had been contracted originally by the Borrower.

     Section 9.20. USA PATRIOT Act Notice. Each Bank that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.

     Pursuant to section 26.02 of the Texas business and commerce code, a credit agreement in which the amount involved in the credit agreement exceeds $50,000 in value is not enforceable unless the credit agreement is in writing and signed by the party to be bound or that party’s authorized representative.

     The rights and obligations of the parties to an agreement subject to the preceding paragraph shall be determined solely from the written credit agreement, and any prior oral agreements between the parties are superseded by and merged into the credit agreement. This written Agreement and the Credit Documents, as defined in this Agreement, represent the final agreement among the parties and may not be contradicted by evidence of prior, contemporaneous, or subsequent oral agreements of the parties.

     There are no unwritten oral agreements between the parties.
