The indebtedness of the Borrower to each Bank resulting from the Revolver B Advances owing to such Bank shall be evidenced by a Revolver B Note of the Borrower payable to the order of such Bank.

(e) Increase in Commitments. The Borrower may, at its option and subject to the conditions described in this Section, without the consent of the Banks increase the aggregate Commitments by adding to this Agreement one or more commercial banks or other financial institutions (who shall, upon completion of the requirements stated in this Section 2.01(e), constitute Banks hereunder), or by allowing one or more Banks to increase their Commitments hereunder, so that such added and increased Commitments shall equal the increase in aggregate Commitments effectuated pursuant to this Section 2.01(e); provided that (i) without the consent of all the Bank, no increase in aggregate Commitments pursuant to this Section 2.01(e) shall result in the aggregate Commitments exceeding $85,000,000, (ii) no Bank's Commitment amount shall be increased without the consent of such Bank, (iii) if the increase is being provided by one or more commercial banks or other financial institutions that are not then Banks hereunder, the Administrative Agent shall have approved such commercial bank or other financial institution, such approval not to be unreasonably withheld and (iv) each such commercial bank, financial institution or Bank shall have a proportionate part of the Revolver A Commitments and Revolver B Commitments. The Borrower may exercise its option to so increase the aggregate Commitments only if the following conditions are satisfied:

(i) no Default or Event of Default has occurred and is continuing, and the Borrower shall have delivered a certificate to Administrative Agent from a Responsible Officer of the Borrower stating that no Default or Event of Default exists;

(ii) the representations and warranties of the Borrower contained in Article IV shall be true and correct except to the extent any such representation or warranty is stated to relate solely to an earlier

date, in which case such representation or warranty shall have been true and correct on such earlier date;

(iii) the Guarantors shall have consented to such increase in writing; and

(iv) the Borrower shall execute new Notes evidencing the increased Commitments of the Banks, at any Bank's request.

The Borrower shall give the Administrative Agent three Business Days' notice of the Borrower's intention to increase the aggregate Commitments pursuant to this Section 2.01(e). Such notice shall specify each new commercial bank or other financial institution, if any, the changes in amounts of Commitments that will result, and such other information as reasonably requested by the Administrative Agent. Each new commercial bank or other financial institution, and each Bank agreeing to increase its Commitments, shall execute and deliver to the Administrative Agent a document in form and substance satisfactory to the Administrative Agent pursuant to which it becomes a party hereto or increases its Commitments, as the case may be, which document, in the case of a new commercial bank or other financial institution, shall (among other matters) specify the Applicable Lending Office of such new commercial bank or other financial institution. Upon execution and delivery of such documents, such new commercial bank or other financial institution shall constitute a "Bank" hereunder with the Commitments as specified therein, or such Bank's Commitments shall increase as specified therein, as the case may be. Notwithstanding the foregoing, after giving effect to this Section, the terms and conditions hereof shall remain substantially the same as on the Effective Date. Further, none of the Banks are obligated to increase their Commitments to comply with this Section.

Section 2.02. Method of Borrowing.

(a) Notice. 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 9:00 a.m. (Los Angeles, California time) (i) on the third Business Day before the date of the proposed Borrowing, in the case of a Eurodollar Rate Borrowing or (ii) 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 11:00 a.m. (Los Angeles, California time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 9.02, or such other location as the Administrative Agent may specify by notice to the Banks, in same day funds, (A) in the case of a Revolver A Borrowing, such Bank's Revolver A Share of such Borrowing and (B) in the case of a Revolver B Borrowing, such Bank's Revolver B Share of such Borrowing. After the Administrative Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent 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 9:00 a.m. (Los Angeles, California time) (i) 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) 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.

(i) at no time shall there be more than four 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 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) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Bank before the date of any Borrowing that such Bank shall not make available to the Administrative Agent such Bank's Revolver A Share of the Revolver A Borrowing or such Bank's Revolver B Share of a Revolver B Borrowing, the Administrative Agent may assume that such Bank has made its Revolver A Share or Revolver B Share, as the case may be, of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made its Revolver A Share or Revolver B Share, as the case may be, of such Borrowing available to the Administrative Agent, such Bank and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate for such day. If such Bank shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Bank's Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

(f) Bank Obligations Several. The failure of any Bank to make the Advance to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any, to make its Advance on the date of such Borrowing. No Bank shall be responsible for the failure of any other Bank to make the Advance to be made by such other Bank on the date of any Borrowing.

Section 2.03. Reduction of the Revolver A 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 Revolver A Commitments or the Revolver B Commitments; provided that each partial reduction shall be in the aggregate amount of $1,000,000 or an integral multiple of $500,000.

(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 11:00 a.m. (Los Angeles, California time) (i) in the case of Eurodollar Rate Advances, at least three Business Days' or (ii) in case of Reference Rate Advances, at least one Business Day's, 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.

(b) Mandatory.

(i) Borrowing Base Deficiency. If the aggregate outstanding amount of Revolver B Advances plus the Letter of Credit Exposure ever exceeds the Borrowing Base, the Borrower shall, after receipt of written notice from the Administrative Agent, prepay Revolver B Advances or, if the Revolver B Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure, such that the Borrowing Base deficiency is cured within 10 days after the date such notice is received.

(ii) Reduction of Commitments. On the date of each reduction of the aggregate Revolver A Commitments pursuant to Section 2.03, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Revolver A Advances to the extent, if any, that the aggregate unpaid principal amount of all Revolver A Advances exceeds the Revolver A Commitments. On the date of each reduction of the aggregate Revolver B Commitments pursuant to Section 2.03, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Revolver B Advances to the extent, if any, that the aggregate unpaid principal amount of all Revolver B Advances plus the Letter of Credit Exposure exceeds the lesser of (i) the Revolver B Commitments and (ii) the Borrowing Base.

(iii) Clean-Up of Revolver B Advances. During each calendar year there shall be a period of at least fifteen consecutive days during which no Revolver B Advances shall be made or shall be outstanding.

(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 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, no later than 11:00 a.m. (Los Angeles, California, time) (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.

(a) Revolver A Advances. The Borrower shall repay the outstanding principal amount of the Revolver A Advances outstanding on the Revolver A Termination Date in (i) equal quarterly installments each in an amount equal to ¹/20^th of the outstanding principal amount of the Revolver A Advances outstanding on the Revolver A Termination Date on the last day of each April, July, October and January beginning on the first such day occurring after the Revolver A Termination Date and continuing thereafter until the last day of April, July, October and January preceding the Final Maturity Date and (ii) one final payment of the remaining outstanding principal balance on the Final Maturity Date.

(b) Revolver B Advances. The Borrower shall repay the outstanding principal amount of the Revolver B Advances on the Revolver B 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 Revolver A Commitment exceeds such Bank's outstanding Revolver A Advances, at the Applicable Margin for commitment fees from the date of this Agreement until the Revolver A 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 Revolver A Termination Date and on the Revolver A Termination Date.

(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 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 Revolving B Termination Date and on the Revolver B 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 in the amounts set forth from time to time as the Issuing Bank's published scheduled fees for such services.

(d) Commitment Increase Fees. The Borrower agrees to pay to the Administrative Agent for the benefit of each Bank increasing its Commitment(s) after the Effective Date a fee equal to .50% of the amount of such increase on the date such increase is effective.

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 3.00% 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 to the Adjusted Reference Rate in effect from time to time plus the Applicable Margin plus 3.00% per annum, payable on demand.

(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. The Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Los Angeles, California, time) on the day when due in Dollars to the Administrative Agent at ▇▇▇ ▇. ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (or such other location as the Administrative Agent shall designate in writing to the Borrower), in same day funds and shall send notice of such payments to the Administrative Agent at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, Mail Code ▇-▇▇▇-▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (facsimile no. (▇▇▇) ▇▇▇-▇▇▇▇). 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 8.05, 9.04 or 9.07) (i) before the occurrence of a Default or Event of Default, (A) in the case of payments in respect of Revolver A Advances, in accordance with each Bank's Revolver A Share and (B) in the case of payments in respect of Revolver B Advances and Letters of Credit, in accordance with each Bank's Revolver B Share and (ii) after the occurrence of a Default or an Event of Default, 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) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Banks that the Borrower shall not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such bank, together with interest, for each day from the date such amount is distributed to such bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate for such day.

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, Revolver A Share, or Revolver B Share, as applicable, 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 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 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 under the laws of which such Bank, the Issuing Bank or the Administrative Agent (as the case may be) is organized or any political subdivision of the jurisdiction (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.

(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 Acceptance (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; 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. 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 Revolver B Termination Date, at the request of the Borrower, the Issuing Bank shall, 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 Guarantor on any Business Day; provided however, that for any Letter of Credit issued for the account of any Guarantor, the Borrower will be joint and severally liable for the reimbursement obligations of such Guarantor under such Letter of Credit as provided in subsection (h) below. No Letter of Credit shall be issued, increased, or extended:

(i) unless such issuance, increase, or extension would not cause the Letter of Credit Exposure to exceed the lesser of (A) $25,000,000.00 or (B) the lesser of (1) the Revolver B Commitment less the aggregate outstanding principal amount of all Revolver B Advances and (2) the Borrowing Base less the aggregate outstanding principal amount of all Revolver B Advances;

(ii) unless such Letter of Credit has an Expiration Date not later than the earlier of (A) 24 months after the date of issuance thereof (or, if extendable beyond such period, unless such Letter of Credit is cancelable upon at least 30 days' notice given by the Issuing Bank to the beneficiary of such Letter of Credit) and (B) 5 days prior to the Revolver B Termination Date;

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

(iv) unless such Letter of Credit is either a Performance Letter of Credit or a Financial Letter of Credit not supporting the repayment of indebtedness for borrowed money of any Person; and

(v) unless the Borrower or such applicable Guarantor has delivered to the Issuing Bank a completed and executed Letter of Credit Application.

(b) Participations. On the Effective Date with respect to the Existing Letters of Credit and upon the date of the issuance or increase of a Letter of Credit, the Issuing Bank shall be deemed to have sold to each other Bank and each other Bank shall have been deemed to have purchased from the Issuing Bank a participation in the related Letter of Credit Obligations equal to such Bank's Revolver B Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Bank shall promptly notify each such participant Bank by telex, telephone, or telecopy of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Bank's participation in such Letter of Credit.

(c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application), given not later than 11:00 a.m. (Los Angeles, California, time) on the fifth Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and the Administrative Agent shall give to each Bank prompt notice of thereof by telex, telephone or telecopy. Each Letter of Credit Application shall be given by telecopier or telex, confirmed immediately in writing, specifying the information required therein. After the Issuing Bank's receipt of such Letter of Credit Application and upon fulfillment of the applicable conditions set forth in Article III, the Issuing Bank shall issue, increase, or extend such Letter of Credit for the account of the Borrower or a Guarantor. Each Letter of Credit Application shall be irrevocable and binding on the Borrower or such applicable Guarantor.

(d) Reimbursement. The Borrower or such applicable Guarantor hereby agrees to pay on demand to the Issuing Bank an amount equal to any amount paid by the Issuing Bank under any Letter of Credit. In the event the Issuing Bank makes a payment pursuant to a request for draw presented under

a Letter of Credit and such payment is not promptly reimbursed by the Borrower or such Guarantor upon demand, the Issuing Bank shall give the Administrative Agent notice of the Borrower's failure to make such reimbursement and the Administrative Agent shall promptly notify each Bank of the amount necessary to reimburse the Issuing Bank. Upon such notice from the Administrative Agent, each Bank shall promptly reimburse the Issuing Bank for such Bank's Revolver B Share of such amount and such reimbursement shall be deemed for all purposes of this Agreement to be a Revolver B Advance to the Borrower transferred at the Borrower's request to the Issuing Bank. If such reimbursement is not made by any Bank to the Issuing Bank on the same day on which the Administrative Agent notifies such Bank to make reimbursement to the Issuing Bank hereunder, such Bank shall pay interest on its Revolver B Share thereof to the Issuing Bank at a rate per annum equal to the Federal Funds Rate. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Banks to record and otherwise treat such reimbursements to the Issuing Bank as Reference Rate Advances under a Revolver B Borrowing requested by the Borrower to reimburse the Issuing Bank which have been transferred to the Issuing Bank at the Borrower's request.

(e) Obligations Unconditional. The obligations of the Borrower and the Guarantors under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Letter of Credit Documents;

(ii) any amendment or waiver of, or any consent to, departure from any Letter of Credit Documents;

(iii) the existence of any claim, set-off, defense, or other right which the Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, or any other person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents, or any unrelated transaction;

(iv) any statement or any 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 to the extent the Issuing Bank would not be liable therefor pursuant to the following paragraph (f); or

(v) payment by the Issuing Bank under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit;

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the Borrower's rights under Section 2.13(f) below.

(f) Liability of Issuing Bank. The Borrower and the Guarantors assume all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency, or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged;

(iii) payment by the Issuing Bank against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING BANK'S OWN NEGLIGENCE),

except that the Borrower and the Guarantors shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Borrower and the Guarantors, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or any Guarantor which the Borrower or such Guarantor proves were caused by (A) the Issuing Bank's willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) the Issuing Bank's willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such 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.

(g) Cash Collateral Account.

(i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.04(b), 7.02(b), or 7.03(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Administrative Agent's standard form assignment of deposit accounts, that the Administrative Agent reasonably requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent a first priority security interest in such account and the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in the Cash Collateral Account, whenever established, all funds held in the Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Obligations.

(ii) So long as no Event of Default Exists, (A) the Administrative Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Administrative Agent shall release to the Borrower at the Borrower's written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any Event of Default, the Administrative Agent may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Administrative Agent, regardless of any Letter of Credit Exposure which may remain outstanding. The Administrative Agent may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account.

(iii) The Administrative Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

(h) Joint and Severally Liability of the Borrower. The Borrower hereby jointly and severally irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with each other Guarantor, with respect to the payment and performance of all of the obligations arising under this Section 2.13 and the Letters of Credit, it being the intention of the parties hereto that all of the obligations of each Guarantor shall be the joint and several obligations of such Guarantor and the Borrower without preference or distinction between them. If and to the extent that any of the Guarantors shall fail to make any payment with respect to any of the obligations

hereunder as and when due or to perform any of such obligations in accordance with the terms thereof, then in each such event the Borrower will make such payment with respect to, or perform, such obligation. The obligations of the Borrower under the provisions of this Section 2.13(h) constitute full recourse obligations of the Borrower enforceable against it to the full extent of its Property, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstance whatsoever. The Borrower hereby waives notice of acceptance of its joint and several liability, notice of any and all Letters of Credit issued under this Agreement, notice of any demand for any payment under this Agreement, notice of any action at any time taken or omitted by the Administrative Agent or the Issuing Bank under or in respect of any of the obligations hereunder, and generally, all demands, notices and other formalities of every kind in connection with this Agreement; provided however, that the Issuing Bank agrees to promptly notify the Borrower of any demands for payment under any Letter of Credit issued pursuant to this Agreement received by the Issuing Bank, provided that the failure to give such notice shall not affect the validity or enforceability of the Borrower's obligations under this Section 2.13(h). It is the intention of the Borrower that, so long as any of the obligations hereunder remain unsatisfied, the obligations of the Borrower under this Section 2.13(h) shall not be discharged except by performance and then only to the extent of such performance. If at any time, any payment, or any part thereof, made in respect of any of the obligations, is rescinded or must otherwise be restored or returned by the Administrative Agent or the Issuing Bank upon the insolvency, bankruptcy or reorganization of any of the Guarantors, or otherwise, the provisions of this Section 2.13(h) will forthwith be reinstated in effect, as though such payment had not been made.

(i) LC Application. Notwithstanding the foregoing, in the event that any of the terms or provisions of any Letter of Credit Application conflict with any terms or provisions of this Agreement, the terms or provisions of this Agreement shall govern and control for all purposes.

Section 2.14. Replacement of Banks under Certain Circumstances. If at any time (a) the Borrower becomes obligated to pay any additional amount to a Bank as described in Section 2.11 or 2.12 or any Bank ceases to make Eurodollar Rate Advances pursuant to Section 2.02(c), (b) any Bank becomes insolvent and its assets become subject to a receiver, liquidator, trustee, custodian or other Person having similar powers, (c) any Bank becomes a "Non-Consenting Lender" (as defined below in this Section 2.14) or (d) any Bank becomes a "Non-Funding Lender" (as defined below in this Section 2.14), then the Borrower may replace such Bank by causing such Bank to (and such Bank shall be obligated to) assign pursuant to Section 9.06 all of its rights and obligations under this Agreement to a Bank or other Person selected by the Borrower and reasonably acceptable to the Administrative Agent, for a purchase price equal to the outstanding principal amount of such Bank's Advances and all accrued interest and fees and other amounts payable hereunder. 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 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 Lender". In the event that any Bank fails to make an Advance required to be made by it hereunder or gives notice to the Administrative Agent that it will not make, or that it has disaffirmed or repudiated any obligation to make, an Advance required to be made by it hereunder, such Bank shall be a "Non-Funding Lender". The Borrower's right to replace a Non-Funding Lender pursuant to this Section 2.14 is in addition to, and not in lieu of, all other rights and remedies available to the Borrower against such Non-Funding Lender under this Agreement or otherwise.

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, the Notes held by 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 both Revolver A Advances and Revolver B 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 Acceptance 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 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 Acceptance, together with the Notes 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 Acceptance, 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 Acceptance, 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 Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance 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 Acceptance, 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 Acceptance, 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 Acceptance; (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 Acceptance 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 Acceptance executed by a Bank and an Eligible Assignee, together with the Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit E, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower shall execute and deliver to the Administrative Agent in exchange for the surrendered Notes (A) if such Eligible Assignee has acquired a Revolver A Commitment, a new Revolver A Note to the order of such Eligible Assignee in an amount equal to the Revolver A Commitment assumed by it pursuant to such Assignment and Acceptance and, if such Eligible Assignee has acquired a Revolver B Commitment, a new Revolver B Note to the order of such Eligible Assignee in an amount equal to the Revolver B Commitment assumed by it pursuant to such Assignment and Acceptance and (B) if such Bank has retained any Revolver A Commitment hereunder, a new Revolver A Note to the order of such Bank in an amount equal to the Revolver A Commitment retained by it hereunder and, if such Bank has retained any Revolver B Commitment, a new Revolver B Note to the order of such Bank in an amount equal to the Revolver B Commitment retained by its hereunder. Such new Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of the attached Exhibit A-1 and A-2, respectively.

(e) Participations. Each Bank may sell participations to one or more banks or other entities 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 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 any Collateral, or extending the Revolver A Termination Date, Revolver B Termination Date or the Final Maturity 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 9.07 as a Bank to the extent of their respective participations.

Section 9.07. Indemnification. THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH BANK AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS FROM, AND DISCHARGE, RELEASE, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, CLAIMS, EXPENSES, OR DAMAGES OF ANY KIND OR NATURE WHATSOEVER TO WHICH

ANY OF THEM MAY BECOME SUBJECT RELATING TO OR ARISING OUT OF THIS AGREEMENT, INCLUDING ANY LIABILITIES, OBLIGATIONS, LOSSES, CLAIMS, EXPENSES, OR DAMAGES WHICH ARISE OUT OF OR RESULT FROM (I) ANY ACTUAL OR PROPOSED USE BY THE BORROWER OR ANY AFFILIATE OF THE BORROWER OF THE PROCEEDS OF THE ADVANCES, (II) ANY BREACH BY THE BORROWER OF ANY PROVISION OF THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, (III) ANY INVESTIGATION, LITIGATION OR OTHER PROCEEDING (INCLUDING OR ANY THREATENED INVESTIGATION OR PROCEEDING) RELATING TO THE FOREGOING, (IV) ANY ENVIRONMENTAL CLAIM OR REQUIREMENT OF ENVIRONMENTAL LAWS CONCERNING OR RELATING TO THE PRESENT OR PREVIOUSLY-OWNED OR OPERATED PROPERTIES OF THE BORROWER, OR THE OPERATIONS OR BUSINESS, OF THE BORROWER, OR (V) ANY ENVIRONMENTAL CLAIM OR REQUIREMENT OF ENVIRONMENTAL LAWS CONCERNING OR RELATED TO THE BORROWER'S PROPERTIES AND THE BORROWER SHALL REIMBURSE THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH BANK AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS, UPON DEMAND FOR ANY REASONABLE OUT-OF-POCKET EXPENSES (INCLUDING REASONABLE OUTSIDE LEGAL FEES) INCURRED IN CONNECTION WITH ANY SUCH INVESTIGATION, LITIGATION OR OTHER PROCEEDING; AND EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED'S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED.

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 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, etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Credit Documents, the making of the Advances and any investigation made by or on behalf of the Administrative Agent or any Bank, none of which investigations shall diminish the Administrative Agent's or any Bank's right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.10, 2.11, 2.12, 9.04 and 9.07 and all of the obligations of the Banks in Section 2.09 and 8.05 shall survive any termination of this Agreement and repayment in full of the Obligations.

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. Business Loans. The Borrower warrants and represents that the Advances evidenced by the Notes are and shall be for business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One ("Chapter One") of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the "indicated rate ceiling" (as such term is defined in Chapter One) from time-to-time in effect.

Section 9.12. 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 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 Notes (or if its Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes 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 Notes (or, if the Notes 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 Note, all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations.

Section 9.13. Waiver of Jury; Consent to Jurisdiction. THE BORROWER, THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH BANK HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR ANY OTHER CREDIT DOCUMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY. 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 9.14. Claims Subject to Judicial Reference; Selection of Referee. ALL CLAIMS, INCLUDING ANY AND ALL QUESTIONS OF LAW OR FACT RELATING THERETO, SHALL, AT THE WRITTEN REQUEST OF ANY PARTY HERETO, BE DETERMINED BY REFERENCE (AS DEFINED BELOW). THE PARTIES HERETO SHALL SELECT A SINGLE REFEREE, WHO SHALL BE A RETIRED STATE OR FEDERAL COURT JUDGE WITH AT LEAST FIVE YEARS OF JUDICIAL EXPERIENCE IN CIVIL MATTERS. IN THE EVENT THAT THE PARTIES CANNOT AGREE UPON A REFEREE, THE REFEREE SHALL BE APPOINTED BY THE COURT. THE PARTIES SHALL EQUALLY BEAR THE FEES AND EXPENSES OF THE REFEREE UNLESS THE REFEREE OTHERWISE PROVIDES IN THE STATEMENT OF DECISION. THE REFERENCE SHALL BE CONDUCTED PURSUANT TO APPLICABLE LAW. THE REFEREE SHALL DETERMINE ALL ISSUES RELATING TO THE APPLICABILITY, INTERPRETATION, LEGALITY AND ENFORCEABILITY OF THIS AGREEMENT. IN THE EVENT THAT MULTIPLE CLAIMS ARE ASSERTED, SOME OF WHICH ARE FOUND NOT SUBJECT TO THIS AGREEMENT, THE PARTIES HERETO AGREE TO STAY THE PROCEEDINGS OF THE CLAIMS NOT SUBJECT TO THIS AGREEMENT UNTIL ALL OTHER CLAIMS ARE RESOLVED IN ACCORDANCE WITH THIS AGREEMENT. IN THE EVENT THAT CLAIMS ARE ASSERTED AGAINST MULTIPLE PARTIES, SOME OF WHOM ARE NOT SUBJECT TO THIS AGREEMENT, THE PARTIES AGREE TO SEVER THE CLAIMS SUBJECT TO THIS AGREEMENT AND RESOLVE THEM IN ACCORDANCE WITH THIS AGREEMENT. IN THE EVENT OF ANY CHALLENGE TO THE LEGALITY OR ENFORCEABILITY OF THIS AGREEMENT, THE PREVAILING PARTY SHALL BE ENTITLED TO RECOVER THE COSTS AND EXPENSES, INCLUDING REASONABLE ATTORNEYS' FEES, INCURRED BY IT IN CONNECTION THEREWITH. AS USED IN THIS SECTION 9.14, "CLAIM" SHALL MEAN, CAUSE OF ACTION, ACTION, DISPUTE OR CONTROVERSY BETWEEN OR AMONG THE PARTIES HERETO, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, WHICH ARISES OUT OF OR RELATES TO: (I) ANY OF THE CREDIT DOCUMENTS; (II) ANY NEGOTIATIONS OR COMMUNICATIONS RELATING TO ANY OF THE CREDIT DOCUMENTS, WITHER OR NOT INCORPORATED INTO THE CREDIT DOCUMENTS OR ANY INDEBTEDNESS EVIDENCED THEREBY; OR (III) ANY ALLEGED AGREEMENTS, PROMISES, REPRESENTATIONS OR TRANSACTIONS IN

CONNECTION THEREWITH, AND "REFERENCE" SHALL MEAN A JUDICIAL REFERENCE CONDUCTED PURSUANT TO THIS AGREEMENT IN ACCORDANCE WITH APPLICABLE LAW, AS IN EFFECT AT THE TIME THE REFEREE IS SELECTED PURSUANT TO THIS SECTION 9.14.

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, 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). Each Letter of Credit shall be governed by the Uniform Customs and Practice for Documentary Credits, International Chamber of Commerce Publication No. 500 (1993 version).

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, the Notes 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 Revolver A Note dated December 19, 2001, in the principal amount of $30,000,000 executed by the Borrower to the order of Union Bank of California, N.A., the Revolver A Note dated December 19, 2001, in the principal amount of $30,000,000 executed by the Borrower to the order of Fleet National Bank, the Revolver B Note dated December 19, 2001, in the principal amount of $7,500,000 executed by the Borrower to the order of Union Bank of California, N.A., and the Revolver B Note dated December 19, 2001, in the principal amount of $7,500,000 executed by the Borrower to the order of Fleet National Bank, each bearing interest and being due and payable as therein provided.

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.
