(e) The Borrower agrees that, upon the request to the Administrative Agent by any Lender, the Borrower will promptly execute and deliver to such Lender a promissory note of the Borrower evidencing any Loans of such Lender, substantially in the form of Exhibit F (a “Note”), with appropriate insertions as to date and principal amount;provided, that delivery of Notes shall not be a condition precedent to the occurrence of the Closing Date or the making of the extensions of credit on the Closing Date.

2.5Commitment Fees, etc. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender, a commitment fee for the period from and including the Closing Date to the last day of the Commitment Period, computed at the Commitment Fee Rate on the average daily amount of the Available Commitment of such Lender during the period for which payment is made.

(b) The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates from time to time agreed to in writing by the Borrower and the Administrative Agent.

2.6Termination or Reduction of Credit Commitments. The Borrower shall have the right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Commitments or, from time to time, to reduce the aggregate amount of the Commitments;provided that no such termination or reduction of Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the Total Extensions of Credit would exceed the Total Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently the Commitments then in effect.

2.7Optional Prepayments. The Borrower may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty (except as otherwise provided herein), upon irrevocable notice delivered to the Administrative Agent at least three Business Days prior thereto in the case of Eurodollar Loans and at least one Business Day prior thereto in the case of Base Rate Loans, which notice shall specify the date and amount of such prepayment and whether such prepayment is of Eurodollar Loans or Base Rate Loans;provided, that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.17. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Base Rate Loans) accrued interest to such date on the amount prepaid. Partial prepayments of Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof.

2.8Mandatory Prepayments. If, at any time during the Commitment Period, the amount of the Total Extensions of Credit exceeds the lesser of (i) the Borrowing Base and (ii) the Total Commitments then in effect (whether as a result of the sale of, or any casualty or condemnation with respect to, assets included in the Borrowing Base or otherwise), the Borrower shall, without notice or demand, prepay, in accordance with this Section, the Loans in an aggregate principal amount equal to such excess, together (except in the case of Base Rate Loans) with interest accrued to the date of such payment or prepayment;provided that if the

aggregate principal amount of Loans then outstanding is less than the amount of such excess (because L/C Obligations constitute a portion thereof), the Borrower shall, to the extent of the balance of such excess, cash collateralize outstanding Letters of Credit in the manner described in Section 3.10(ii).

2.9Conversion and Continuation Options. (a) The Borrower may elect from time to time to convert Eurodollar Loans to Base Rate Loans by giving the Administrative Agent at least two Business Days’ prior irrevocable notice of such election,provided that any such conversion of Eurodollar Loans may be made only on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert Base Rate Loans to Eurodollar Loans by giving the Administrative Agent at least three Business Days’ prior irrevocable notice of such election (which notice shall specify the length of the initial Interest Period therefor),provided that no Base Rate Loan may be converted into a Eurodollar Loan (i) when any Event of Default has occurred and is continuing and the Administrative Agent has, or the Required Lenders have, determined in its or their sole discretion not to permit such conversions or (ii) after the date that is one month prior to the Termination Date. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

(b) The Borrower may elect to continue any Eurodollar Loan as such upon the expiration of the then current Interest Period with respect thereto by giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans,provided that no Eurodollar Loan may be continued as such (i) when any Event of Default has occurred and is continuing and the Administrative Agent has, or the Required Lenders have, determined in its or their sole discretion not to permit such continuations or (ii) after the date that is one month prior to the Termination Date, andprovided,further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso, such Loans shall be converted automatically to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.10Minimum Amounts and Maximum Number of Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions, continuations and optional prepayments of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than five Eurodollar Tranches shall be outstanding at any one time.

2.11Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin in effect for such day.

(b) Each Base Rate Loan shall bear interest for each day on which it is outstanding at a rate per annum equal to the Base Rate in effect for such day plus the Applicable Margin in effect for such day.

(c) (i) If all or a portion of the principal amount of any Loan or Reimbursement Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), all outstanding Loans and Reimbursement Obligations (whether or not overdue) (to the extent legally permitted) shall bear interest at a rate per annum that is equal to (x) in the case of the Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% or (y) in the case of Reimbursement Obligations, the rate applicable to Base Rate Loans plus 2%, and (ii) if all or a portion of any interest payable on any Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to Base Rate Loans plus 2%, in each case, with respect to clauses (i) and (ii) above, from the date of such non-payment until such amount is paid in full (after as well as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand.

2.12Computation of Interest and Fees. (a) Interest, fees, commissions payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to Base Rate Loans on which interest is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.12(a).

2.13Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then current Interest Period with respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans.

2.14Pro Rata Treatment and Payments. (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee or Letter of Credit fee, and any reduction of the Commitments of the Lenders, shall be madeprorata according to the respective Percentages of the Lenders.

(b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Loans shall be madeprorata according to the respective outstanding principal amounts of the Loans then held by the Lenders. Each payment in respect of Reimbursement Obligations in respect of any Letter of Credit shall be made to the Issuing Lender that issued such Letters of Credit.

(c) The application of any payment of Loans (including optional and mandatory prepayments) shall be made,first, to Base Rate Loans and,second, to Eurodollar Loans. Each payment of the Loans (except in the case of Base Rate Loans) shall be accompanied by accrued interest to the date of such payment on the amount paid.

(d) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the relevant Lenders, at the Payment Office, in Dollars and in immediately available funds. Any payment made by the Borrower after 12:00 Noon, New York City time, on any Business Day shall be deemed to have been on the next following Business Day. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(e) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the

Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender��s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans, on demand, from the Borrower.

(f) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respectiveprorata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

(g) Notwithstanding any other provision of this Agreement or any other Loan Document, any proceeds of any foreclosure or other realization by the Administrative Agent in respect of any Collateral shall be applied as provided in the Guarantee and Collateral Agreement.

2.15Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

	(i)		shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.16 and changes in the rate of tax on the overall net income of such Lender);

	(ii)		shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate hereunder; or

(iii)

shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.16Taxes. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes imposed on any Agent or any Lender as a result of a present or former connection between such Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Agent’s or such Lender’s having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or any Other Taxes are required to be withheld from any amounts payable to any Agent or any Lender hereunder, the amounts so payable to such Agent or such Lender shall be increased to the extent necessary to yield to such Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement;provided,however,

that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph (a).

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

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for the account of the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(d) Each Lender (or Transferee) that is not a citizen or resident of the United States of America, a corporation, partnership or other entity created or organized in or under the laws of the United States of America (or any jurisdiction thereof), or any estate or trust that is subject to federal income taxation regardless of the source of its income (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest” a statement substantially in the form of Exhibit H and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(e) A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate,provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

2.17Indemnity. The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss (other than loss of anticipated profits) or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment or conversion of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.18Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be suspended for the duration of such illegality and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.17.

2.19Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.15, 2.16(a) or 2.18 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event;provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, andprovided,further, that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to Section 2.15, 2.16(a) or 2.18.

2.20Replacement of Lenders under Certain Circumstances. The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.15 or 2.16 or gives a notice of illegality pursuant to Section 2.18 or (b) defaults in its obligation to make Loans hereunder, with a replacement financial institution;provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall have taken no action under Section 2.19 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.15 or 2.16 or to eliminate the illegality referred to in such notice of illegality given pursuant to Section 2.18, (iv) the replacement financial institution shall purchase, at par, all Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.17 (as though Section 2.17 were applicable) if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 10.6 (provided that the replacement financial institution shall be obligated to pay the registration and processing fee referred to therein), (viii) the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.15 or 2.16, as the case may be, in respect of any period prior to the date on which such replacement shall be consummated, (ix) in the event the replaced Lender is an Issuing Lender, the outstanding Letters of Credit issued by such replaced Lender shall be replaced and/or cash-collateralized in an amount and manner satisfactory to such replaced Lender and (x) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

2.21Bank Products. The Borrower may request and any Lender or Affiliate of any Lender may, in its sole and absolute discretion, arrange for the Borrower to obtain from such Lender or such Affiliate Bank Products (which shall be subject to all rules and regulations of such Lender or such Affiliate) although the Borrower is not required to do so.

SECTION 3. LETTERS OF CREDIT

3.1L/C Commitment. (a) Prior to the date hereof, the Existing Issuing Lender has issued the Existing Letters of Credit which, from and after the Closing Date, shall constitute Letters of Credit hereunder. Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 3.4(a), agrees to issue letters of credit (the letters of credit issued on and after the Closing Date pursuant to this Section 3, together with the Existing Letters of Credit collectively, “Letters of Credit”) for the account of the Borrower or any Subsidiary on any Business Day during the Commitment Period in such form as may be approved from time to time by such Issuing Lender;provided that no Issuing Lender shall have any obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment (providedfurther that Bank of America, N.A., in its capacity as Issuing Lender, shall have no obligation to issue any Letter of Credit, if after giving effect to such issuance, the L/C obligations in respect of Letters of Credit issued by it would exceed $40,000,000) or (ii) the aggregate amount of the Available Commitments would be less than zero. Each Letter of Credit shall (i) be denominated in Dollars, or any other currency deemed acceptable by the Administrative Agent and the Issuing Lender,

each in its sole discretion and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date which is five Business Days prior to the Termination Date;provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above). In the case of any Letter of Credit denominated in any currency other than Dollars, it is understood and agreed that, for all purposes of this Agreement, the face amount and drawable amount thereof at the time of issuance, and the amount of any unreimbursed drawing in respect thereof at the end of each subsequent L/C Fee Payment Date or on any applicable date of measurement hereunder, shall be deemed to be the equivalent in Dollars of such amount at such time, in each case as reasonably determined by the Administrative Agent in a manner acceptable to the Administrative Agent, the Borrower and the Issuing Lender in respect of such Letter of Credit.

(b) No Issuing Lender shall at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause such Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law.

3.2Procedure for Issuance of Letter of Credit. The Borrower may from time to time request that an Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender at its address for notices specified herein an Application therefor, completed to the satisfaction of such Issuing Lender, and such other certificates, documents and other papers and information as such Issuing Lender may request. Concurrently with the delivery of an Application to an Issuing Lender, the Borrower shall deliver a copy thereof to the Administrative Agent. Upon receipt of any Application, an Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by such Issuing Lender and the Borrower (but in no event shall any Issuing Lender be required to issue any Letter of Credit earlier than two Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto). Promptly after issuance by an Issuing Lender of a Letter of Credit, such Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower. Each Issuing Lender shall promptly give notice to the Administrative Agent of the issuance of each Letter of Credit issued by such Issuing Lender (including the amount thereof), and shall provide a copy of such Letter of Credit to the Administrative Agent as soon as possible after the date of issuance.

3.3Fees and Other Charges. (a) The Borrower will pay to the Administrative Agent for distribution to the Lenders a fee on the aggregate drawable amount of all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans, to be shared ratably among the Lenders in accordance with their respective Percentages and payable quarterly in arrears on each L/C Fee Payment Date after the issuance date. In addition, the Borrower shall pay to the relevant Issuing Lender for its own account a fronting fee on the aggregate drawable amount of all outstanding Letters of Credit issued by it at the rate per annum agreed upon from time to time by the Borrower and such Issuing Lender, payable quarterly in arrears on each L/C Fee Payment Date after the issuance date.

(b) In addition to the foregoing fees, the Borrower shall pay or reimburse each Issuing Lender for such normal and customary costs and expenses as are incurred or charged by such Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

3.4L/C Participations. (a) Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce each Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases, without recourse or warranty, from each Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant’s own account and risk, an undivided interest equal to such L/C Participant’s Percentage in each Issuing Lender’s obligations and rights under each Letter of Credit issued by such Issuing Lender hereunder and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit issued by such Issuing Lender for which such Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to the Administrative Agent for the account of such Issuing Lender upon demand at such Issuing Lender’s address for notices specified herein (and thereafter the Administrative Agent shall promptly pay to such Issuing Lender) an amount equal to such L/C Participant’s Percentage of the amount of such draft, or any part thereof, that is not so reimbursed.

(b) If any amount (a “Participation Amount”) required to be paid by any L/C Participant to an Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit is paid to such Issuing Lender within three Business Days after the date such payment is due, such Issuing Lender shall so notify the Administrative Agent (which shall notify the L/C Participants), and each L/C Participant shall pay to Administrative Agent, for the account of such Issuing Lender, on demand (and thereafter the Administrative Agent shall promptly pay to such Issuing Lender) an amount equal to the product of (i) such Participation Amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is required to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any Participation Amount required to be paid by any L/C Participant pursuant to Section 3.4(a) is not made available to the Administrative Agent for the account of the relevant Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, the Administrative Agent on behalf of such Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such Participation Amount with interest thereon calculated from such due date at the rate per annum applicable to Base Rate Loans. A certificate of the Administrative Agent on behalf of an Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error.

(c) Whenever, at any time after an Issuing Lender has made payment under any Letter of Credit and has received from the Administrative Agent any L/C Participant’s itsprorata share of such payment in accordance with Section 3.4(a), such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by such Issuing Lender), or any payment of

interest on account thereof, such Issuing Lender will distribute to the Administrative Agent for the account of such L/C Participant (and thereafter the Administrative Agent will promptly distribute to such L/C Participant) itsprorata share thereof;provided,however, that in the event that any such payment received by such Issuing Lender shall be required to be returned by such Issuing Lender, such L/C Participant shall return to the Administrative Agent for the account of such Issuing Lender (and thereafter the Administrative Agent shall promptly return to such Issuing Lender) the portion thereof previously distributed by such Issuing Lender.

3.5Reimbursement Obligation of the Borrower. The Borrower agrees to reimburse each Issuing Lender, on each date on which such Issuing Lender notifies the Borrower of the date and amount of a draft presented under any Letter of Credit (including any Letter of Credit issued for the account of any Subsidiary) and paid by such Issuing Lender, for the amount of (a) such draft so paid and (b) any taxes, fees, charges or other costs or expenses incurred by such Issuing Lender in connection with such payment (the amounts described in the foregoing clauses (a) and (b) in respect of any drawing, collectively, the “Payment Amount”). Each such payment shall be made to such Issuing Lender at its address for notices specified herein in lawful money of the United States of America and in immediately available funds. Interest shall be payable on each Payment Amount from the date of the applicable drawing until payment in full at the rate set forth in (i) until the second Business Day following the date of the applicable drawing, Section 2.11(b) and (ii) thereafter, Section 2.11(c). Each drawing under any Letter of Credit shall (unless an event of the type described in clause (i) or (ii) of Section 8(f) shall have occurred and be continuing with respect to the Borrower, in which case the procedures specified in Section 3.4 for funding by L/C Participants shall apply) constitute a request by the Borrower to the Administrative Agent for a borrowing pursuant to Section 2.2 of Base Rate Loans in the amount of such drawing. The Borrowing Date with respect to such borrowing shall be the first date on which a borrowing of Loans could be made, pursuant to Section 2.2, if the Administrative Agent had received a notice of such borrowing at the time the Administrative Agent receives notice from the relevant Issuing Lender of such drawing under such Letter of Credit.

3.6Obligations Absolute. The Borrower’s obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against any Issuing Lender, any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with each Issuing Lender that such Issuing Lender shall not be responsible for, and the Borrower’s Reimbursement Obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. No Issuing Lender shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Issuing Lender. The Borrower agrees that any action taken or omitted by an Issuing Lender under or in connection with any Letter of Credit issued by it or the related drafts or documents, if done in the absence of

gross negligence or willful misconduct and in accordance with the standards or care specified in the Uniform Commercial Code of the State of New York, shall not excuse the Reimbursement Obligations of the Borrower hereunder and shall not result in any liability of such Issuing Lender to the Borrower.

3.7Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the relevant Issuing Lender shall promptly notify the Borrower and the Administrative Agent of the date and amount thereof. The responsibility of the relevant Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit, in addition to any payment obligation expressly provided for in such Letter of Credit issued by such Issuing Lender, shall be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment appear on their face to be in conformity with such Letter of Credit.

3.8Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply.

Without limitation of the foregoing, each Lender agrees to reimburse each Issuing Lender promptly upon demand for its Percentage of any costs or expenses payable by the Borrower to such Issuing Lender, to the extent that such Issuing Lender is not promptly reimbursed for such costs and expenses by the Borrower. The agreement contained in this Section shall survive payment in full of all Obligations.

(e)Power of Attorney. In connection with all inventory financed by Letters of Credit, the Borrower hereby appoints each Issuing Lender, or such Issuing Lender’s

None of the Issuing Lenders or any of their respective designees, as the Borrower’s attorney, will be liable for any acts or omissions, nor for any error of judgment or mistakes of fact or law. This power, being coupled with an interest, is irrevocable until all Obligations have been paid and satisfied.

(f)Account Party. The Borrower hereby authorizes and directs any Issuing Lender to name the Borrower as the “Account Party” therein and to deliver to the Administrative Agent all instruments, documents and other writings and property received by such Issuing Lender pursuant to the Letter of Credit, and to accept and rely upon the Administrative Agent’s instructions and agreements with respect to all matters arising in connection with the Letter of Credit or the Application therefor.

Reasonable interest shall accrue on any such cash deposit, which accrued interest shall be for the account of the Borrower, subject to this Agreement.

3.11Letters 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 Lender that issued such Letter of Credit for any and all drawings thereunder.

4.1Financial Condition. The audited consolidated balance sheets of the Borrower as at December 31, 2005 and December 31, 2006, and the related consolidated statements of income and of cash flows for the fiscal years ended on such dates, reported on by and accompanied by an unqualified report from PricewaterhouseCoopers LLP, present fairly in all material respects the consolidated financial condition of the Borrower as at such date, and the consolidated results of its operations and its consolidated cash flows for the respective fiscal years then ended. The unaudited consolidated balance sheets of the Borrower as at March 31, 2007 and June 30, 2007, and the related unaudited consolidated statements of income and cash flows for the periods ended on such date, present fairly in all material respects the consolidated financial condition of the Borrower as at such dates, and the consolidated results of its operations and its consolidated cash flows for the quarterly periods then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). The Borrower and its Subsidiaries do not have any material Guarantee Obligations, contingent liabilities and liabilities for taxes (except for any such tax liabilities to taxing authorities outside of the United States which are not, in the aggregate, material to the Borrower and its Subsidiaries taken as a whole) or any long-term leases or unusual forward or long-term commitments, including, without limitation, any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from December 31, 2006 to and including the date hereof there has been no Disposition by the Borrower of any material part of its business or Property, except as reflected in the foregoing financial statements.

4.2No Change. Since December 31, 2006 there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

4.4Corporate Power; Authorization; Enforceable Obligations. Each Loan Party has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to borrow hereunder. Each Loan Party has taken all necessary corporate or other action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the execution, delivery, performance, validity or enforceability of this Agreement or any of the other Loan Documents, except (i) consents, authorizations, filings and notices described in Schedule 4.4, which consents, authorizations, filings and notices have been obtained or made and are in full force and effect (except as noted on Schedule 4.19) and (ii) the filings referred to in Section 4.4.

The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any material Contractual Obligation of the Borrower or any of its Subsidiaries and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or Contractual Obligation applicable to the Borrower or any of its Subsidiaries could reasonably be expected to have a Material Adverse Effect.

4.6No Material Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any of its Subsidiaries or against any of their respective

properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

4.10Taxes. Each of the Borrower and each of its Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its Property and all other taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority (other than (a) any the amount or validity of which are currently being contested in good faith by appropriate proceedings and (b) assessments by the Republic of Kazakhstan, disputed as of the date of this Agreement, in each case, with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or its Subsidiaries, as the case may be); and no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge (other than any such Liens and claims in favor of taxing authorities outside of the United States which are not, in the aggregate, material to the Borrower and its Subsidiaries taken as a whole).

4.11Federal Regulations. No part of the proceeds of any Loans will be used in violation of Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the Regulations of the Board.

4.12Labor Matters. There are no strikes or other labor disputes against the Borrower or any of its Subsidiaries pending or, to the knowledge of the Borrower, threatened that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. Hours worked by and payment made to employees of the Borrower and its Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Requirement of Law dealing with such matters that (individually or in the

aggregate) could reasonably be expected to have a Material Adverse Effect. All payments due from the Borrower or any of its Subsidiaries on account of employee health and welfare insurance that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect if not paid have been paid or accrued as a liability on the books of the Borrower or the relevant Subsidiary.

4.13ERISA. Neither a Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five-year period prior to the date on which this representation is made or deemed made with respect to any Plan, and each Plan has complied in all material respects with the applicable provisions of ERISA and the Code, except where, individually or in the aggregate, such occurrence or noncompliance has not had and could not reasonably be expected to have a Material Adverse Effect. No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by a material amount. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

4.14Investment Company Act; Other Regulations. No Loan Party is an “investment company”, or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. No Loan Party is subject to regulation under any Requirement of Law (other than Regulation X of the Board) which limits its ability to incur Indebtedness.

4.15Subsidiaries. (a) The Subsidiaries listed on Schedule 4.15 constitute all of the Subsidiaries of the Borrower at the date hereof.

(b) As of the date hereof, there are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than stock options granted to employees or directors and directors’ qualifying shares) of any nature relating to any Capital Stock of the Borrower or any Subsidiary, except as disclosed on Schedule 4.15.

4.16Use of Proceeds. The proceeds of the Loans, and the Letters of Credit, shall be used for the general corporate purposes of the Borrower and its Subsidiaries, including to satisfy tax obligations owed by any Loan Party to the Republic of Kazakhstan.

SECTION 9. THE ADMINISTRATIVE AGENT

9.1Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents, and each Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.

9.2Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

9.3Exculpatory Provisions. Neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of

any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

9.4Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Loan Parties), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 10.6 and all actions required by such Section in connection with such transfer shall have been taken. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

9.5Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent shall have received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent shall receive such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement);provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

9.6Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property,

financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

9.7Indemnification. The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Percentages immediately prior to such date), for, and to save each Agent harmless from and against, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing;provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

9.8Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Loans made or renewed by it and with respect to any Letter of Credit issued or participated in by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in its individual capacity.

9.9Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 10 days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other

Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

9.10Authorization to Release Liens and Guarantees. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to effect any release of Liens or guarantee obligations contemplated by Section 10.15.

9.11The Arrangers; the Syndication Agent. Neither the Arrangers nor the Syndication Agent, in their respective capacities as such, shall have no duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents.

All amounts due under this Section shall be payable not later than 30 days after written demand therefor. Statements payable by the Borrower pursuant to this Section shall be submitted to the Borrower at the address of the Borrower set forth in Section 10.2, or to such other Person or address as may be hereafter designated by the Borrower in a notice to the Administrative Agent.

10.6Successors and Assigns; Participations and Assignments. (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent, all future holders of the Loans and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent and each Lender.

(b) Any Lender may, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or consent would require the consent of the Lender from whom such Participant purchased such participation pursuant to Section 10.1. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be

deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement,provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender;provided that, in the case of Section 2.16, such Participant shall have complied with the requirements of said Section, andprovided,further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

(c) Any Lender (an “Assignor”) may, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any affiliate, Related Fund or Control Investment Affiliate thereof or, with the consent of the Borrower and the Administrative Agent and the written consent of the Issuing Lender (which, in each case, shall not be unreasonably withheld or delayed) (provided (x) that no such consent need be obtained by the Administrative Agent or any of its Affiliates and (y) the consent of the Borrower need not be obtained with respect to any assignment if an Event of Default shall have occurred and be continuing), to an additional bank, financial institution or other entity that is not a competitor of the Borrower or its Subsidiaries (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit D, executed by such Assignee and such Assignor (and, where the consent of the Borrower, the Administrative Agent or the Issuing Lender is required pursuant to the foregoing provisions, by the Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register;provided that ((i) no such assignment to an Assignee (other than any Lender or any affiliate thereof) shall be in an aggregate principal amount of less than $2,500,000 and (ii) after giving effect thereto, the assigning Lender shall have Commitments and Loans aggregating at least $2,500,000, unless otherwise agreed by the Borrower and the Administrative Agent (in each case other than in the case of an assignment of all of a Lender’s interests under the Facility), unless otherwise agreed by the Borrower and the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with Commitments and/or Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor’s rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to Section 2.15, 2.16 and 10.5 in respect of the period prior to such effective date). Notwithstanding any provision of this Section, the consent of the Borrower shall not be required for any assignment that occurs at any time when any Event of Default shall have occurred and be continuing. For purposes of the minimum assignment amounts set forth in this paragraph, multiple assignments by or to two or more Related Funds, or to two or more funds that will be Related Funds after giving effect to such assignments, shall be aggregated.

(d) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 10.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Notes evidencing such Loans recorded therein for all purposes of this Agreement. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the Administrative Agent to the Borrower marked “canceled”. The Register shall be available for inspection by the Borrower or any Lender (with respect to any entry relating to such Lender’s Loans) at any reasonable time and from time to time upon reasonable prior notice.

(e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 10.6(c), by each such other Person) together with payment to the Administrative Agent of a registration and processing fee of $3,500 (treating multiple, simultaneous assignments by or to two or more Related Funds, or to two or more funds that will be Related Funds after giving effect to such assignments, as a single assignment) (except that no such registration and processing fee shall be payable in the case of an Assignee which is already a Lender or is an affiliate or Related Fund of a Lender or a Person under common management with a Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. On or prior to such effective date, the Borrower, at its own expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the Note of the assigning Lender) a new Note to the order of such Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Commitment, upon request, a new Note to the order of the Assignor in an amount equal to the Commitment retained by it hereunder. Such new Note shall be dated the Closing Date and shall otherwise be in the form of the Note replaced thereby.

(f) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Loans and Notes, including, without limitation, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law.

10.7Adjustments; Set-off. (a) Except to the extent that this Agreement provides for payments to be allocated to a particular Lender, if any Lender (a “Benefitted Lender”) shall at any time receive any payment of all or part of the Obligations owing to it, or

receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Obligations, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Obligations, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the other Lenders;provided,however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender,provided that the failure to give such notice shall not affect the validity of such setoff and application.

10.8Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement or of a Lender Addendum by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent.

10.9Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payment had not been made.

10.16Accounting Changes. In the event that any “Accounting Change” (as defined below) shall occur and such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then the Borrower and the Administrative Agent agree to enter into negotiations in order to amend such provisions of this Agreement so as to equitably reflect such Accounting Change with the desired result that the criteria for evaluating the Borrower’s financial condition shall be the same after such Accounting Change as if such Accounting Change had not been made.

10.18Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Loan Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, from time to time in effect governing the Loans of each Lender. In furtherance thereof, the Lenders and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Loan 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 nonusurious interest rate under applicable law (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 in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Loans, 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 each Lender receiving same shall credit the same on the principal of its Loans (or if such Loans shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of any Loans 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 applicable Loans (or, if the applicable Loans shall have been paid in full, refunded to the Borrower). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower and the Lenders 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 Loans all amounts

considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations. The provisions of this Section 10.18 shall control over all other provisions of this Agreement or the other Loan Documents which may be in apparent conflict herewith.

10.19WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

10.20USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (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 each Loan Party, which information includes the name and address of each Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify each Loan Party in accordance with the Act.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed and delivered by their proper and duly authorized officers as of the day and year first above written.
