ARTICLE II.
THE REVOLVING COMMITMENT AND BORROWINGS

2.01 Revolving Loans. Subject to and in reliance upon the terms, conditions, representations, and warranties in the Loan Documents, each Lender severally, but not jointly, agrees to make revolving loans (each such loan a “Revolving Loan”) to Borrower from time to time on any Business Day during the period from the Second Amended and Restated Closing Date to the Maturity Date, in an aggregate amount not to exceed at any time outstanding the amount of such Lender’s Pro Rata Share of one or more Revolving Loan Borrowings not to exceed, when aggregated with the Outstanding Amount of the L/C Obligations, such Lender’s Revolving Commitment. Revolving Loan Borrowings may be repaid and reborrowed from time to time in accordance with the terms and provisions of the Loan Documents; provided that, each such Revolving Loan Borrowing must occur on a Business Day and no later than the Business Day immediately preceding the Maturity Date. Revolving Loans may be Base Rate Loans or Eurodollar Rate Loans, as further provided herein; provided, however, all Revolving Loan Borrowings made on the Second Amended and Restated Closing Date shall be made as Base Rate Loans.

2.02 Borrowings, Conversions and Continuations of Revolving Loans.

(a) Each Borrowing, each conversion of Revolving Loans from one interest rate Type to the other, and each continuation of Revolving Loans as the same interest rate Type shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which may be given by telephone. Each such notice must be received by the Administrative Agent not later than 11:00 a.m., New York time, three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans, and one Business Day prior to the requested date of any Borrowing of, conversion to or continuation of Base Rate Loans. Each such telephonic notice must be confirmed promptly by delivery to the Administrative Agent of a written Borrowing Notice, appropriately completed and signed by an authorized officer of the Borrower. Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $500,000 in excess thereof. Each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each Borrowing Notice (whether telephonic or written) shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of Revolving Loans from one interest rate Type to the other, or a continuation of Revolving Loans as the same interest rate Type, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Revolving Loans to be borrowed, converted or continued, (v) the interest rate Type of Revolving Loans to be borrowed or to which existing Revolving Loans are to be converted, and (vi) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify the interest rate Type for a Revolving Loan in a Borrowing Notice or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Revolving Loans shall be made or continued as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Borrowing Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(b) Following receipt of a Borrowing Notice, the Administrative Agent shall promptly notify each Lender of its Pro Rata Share of the applicable Revolving Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in the preceding

subsection. In the case of a Borrowing, each Lender shall make the amount of its Revolving Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 11:00 a.m., New York time, on the Business Day specified in the applicable Borrowing Notice. Upon satisfaction of the applicable conditions set forth in Section 4.01 and Section 4.03 (and in the case of a Revolving Loan to fund a Permitted Acquisition, Section 4.04), the Administrative Agent shall make all funds so received available to the Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the Borrower on the books of the Administrative Agent with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to the Administrative Agent by the Borrower; provided, however, that if, on the date of the Borrowing there are L/C Borrowings outstanding, then the proceeds of such Borrowing shall be applied, first, to the payment in full of any such L/C Borrowings, and second, to the Borrower as provided above.

(c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of the Interest Period for such Eurodollar Rate Loan. During the existence of a Default or Event of Default, no Revolving Loans may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the Required Lenders, and the Required Lenders may demand that any or all of the then outstanding Eurodollar Rate Loans be converted to Base Rate Loans at the end of the then current Interest Period.

(d) The Administrative Agent shall promptly notify the Borrower and the Lenders of the interest rate applicable to any Eurodollar Rate Loan upon determination of such interest rate. The determination of the Eurodollar Rate by the Administrative Agent shall be conclusive in the absence of manifest error.

(e) After giving effect to all Borrowings, all conversions of Revolving Loans from one interest rate Type to the other, and all continuations of Revolving Loans as the same interest rate Type, there shall not be more than six (6) Interest Periods in effect at any given time with respect to Revolving Loans.

2.03 Prepayments.

(a) Optional Prepayments. The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay in whole or in part Revolving Loans outstanding under the Revolver Facility without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 11:00 a.m., New York time, (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans, and (B) one Business Day prior to any date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Revolving Loans and the interest rate Type(s) to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of such Lender’s Pro Rata Share of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Each such prepayment shall be applied to the Revolving Loans of the Lenders in accordance with their respective Pro Rata Shares.

Unless a Default or Event of Default has occurred and is continuing or would arise as a result thereof, any payment or prepayment of the Revolving Loans (including prepayments pursuant to Section 2.03(b)) may be reborrowed by Borrower, subject to the terms and conditions hereof.

(b) Mandatory Prepayments from Net Cash Proceeds.

(i) If any portion of the Reduction Amount from any Triggering Sale (including any deferred purchase price therefor) has not been Reinvested within one hundred eighty (180) days from the receipt by Borrower or any Subsidiary of such Reduction Amount (including receipt of any deferred payments for any such Triggering Sale or portion thereof, if and when received), then on the Business Day following such one hundred eightieth (180th) day an amount equal to the portion of the Reduction Amount that is not so Reinvested shall be applied as provided in Section 2.03(b)(iii). Net Cash Proceeds from Insurance Payments and Dispositions that equal, when aggregated with Net Cash Proceeds from all Insurance Payments and Dispositions since the Second Amended and Restated Closing Date, an amount less than the Threshold Amount shall not be required to be applied pursuant to Section 2.03(b)(iii).

(ii) Upon receipt by Borrower or any Subsidiary of any Reduction Amount, the Borrower shall deliver a Triggering Sale Certificate to the Administrative Agent and each Lender pursuant to Section 6.02(c). . If such Reduction Amount has not been Reinvested within one hundred eighty (180) days following its receipt by Borrower or any Subsidiary, on the Business Day following such one hundred eightieth (180^th) day, the Borrower shall deliver to the Administrative Agent a certificate from a Responsible Officer of the Borrower demonstrating pro forma compliance with the Fixed Asset Coverage Ratio covenant set forth in Section 7.19(c) after giving effect to all Triggering Sales.

(iii) Application of Mandatory Prepayments. All amounts required to be paid pursuant to Section 2.03(b)(i) shall be applied as follows:

First, to the payment of any L/C Borrowing;

Second, to the payment of any unpaid fees or expenses of the Administrative Agent;

Third, to the Revolving Loan (without a corresponding reduction in the Aggregate Revolving Commitment); and

Fourth, after all Revolving Loans have been repaid and if any Default or any Event of Default has occurred and is continuing, to Cash Collateralize L/C Obligations.

Within the parameters of the applications set forth above, prepayments shall be applied first to Base Rate Loans and then to Eurodollar Rate Loans in direct order of Interest Period maturities; provided, however, unless a Default or Event of Default has occurred and is continuing or would arise as a result thereof, any prepayment may be reborrowed by Borrower, subject to the terms and conditions hereof. Any amounts used to Cash Collateralize the L/C Obligations pursuant to clause Fourth above shall be released to the Borrower when all Defaults or Events of Default referred to in said clause are no longer continuing.

(c) Prepayments by Reason of Aggregate Revolving Commitment Exceeded. If on any date the Outstanding Amount of all Revolving Loans and L/C Obligations shall exceed the Aggregate Revolving Commitment, then the Borrower shall immediately make mandatory prepayments of Revolving Loans equal to such excess, and if any such excess remains after such prepayments, to the extent of such excess the Borrower shall immediately Cash Collateralize the L/C Obligations.

(d) Prepayments: Interest/Funding Loss. All prepayments under this Section 2.03 shall be subject to Section 3.05, but otherwise without premium or penalty, and shall be accompanied by interest on the principal amount prepaid through the date of prepayment.

2.04 Reduction or Termination of Commitments. The Borrower may, upon notice to the Administrative Agent terminate the Revolving Commitment prior to the Maturity Date to an amount not less than the sum of the Outstanding Amount of the then existing (a) Revolver Principal Debt and (b) L/C Obligations; provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m., five Business Days prior to the date of termination or reduction, and (ii) any such partial reduction shall be in an aggregate amount of $1,000,000 or any whole multiple of $500,000 in excess thereof. The Administrative Agent shall promptly notify the Lenders of any such notice of reduction or termination. Once reduced in accordance with this Section, the Revolving Commitment may not be increased. Any reduction of the Revolving Commitment shall be applied to the corresponding Revolving Commitment of each Lender according to its Pro Rata Share. All commitment fees on the portion of the Revolving Commitment so terminated which have accrued to the effective date of any termination of the Revolving Commitment shall be paid on the effective date of such termination.

2.05 Repayment of Revolving Loans. The Borrower shall repay to the Lenders on the Maturity Date the aggregate Revolver Principal Debt outstanding on such date.

2.06 Interest.

Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

(d) If the designated rate applicable to any Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing shall be limited to the Maximum Rate, but any subsequent reductions in such designated rate shall not reduce the rate of interest thereon below the Maximum Rate until the total

amount of interest accrued thereon equals the amount of interest which would have accrued thereon if such designated rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of the Outstanding Amount of any Revolving Loans or L/C Obligations, the total amount of interest paid or accrued is less than the amount of interest which would have accrued if such designated rates had at all times been in effect, then, at such time and to the extent permitted by Law, the Borrower shall pay an amount equal to the difference between (a) the lesser of the amount of interest which would have accrued if such designated rates had at all times been in effect and the amount of interest which would have accrued if the Maximum Rate had at all times been in effect, and (b) the amount of interest actually paid or accrued on such Outstanding Amount.

Such fees shall be fully earned when paid and shall be nonrefundable for any reason whatsoever. Additionally, Borrower shall pay to the Administrative Agent for the Administrative Agent’s own account the fees in the amounts and on the dates specified in the Agent/Arranger Fee Letter.

2.09 Evidence of Debt.

absent manifest error, of the amount of the Revolving Loans made by the Lenders to the Borrower and the interest and payments thereon. Any failure so to record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Revolving Loans or the L/C Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of such Lender shall control. Upon the request of any Lender made through the Administrative Agent, such Lender’s Revolving Loans may be evidenced by one or more Revolver Notes. Each Lender may attach schedules to its Revolver Note(s) and endorse thereon the date, Type (if applicable), amount and maturity of the applicable Revolving Loans and payments with respect thereto.

(b) In addition to the accounts and records referred to in subsection (a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control.

(b) Subject to the definition of “Interest Period,” if any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(c) If no Default or Event of Default exists and if no order of application is otherwise specified in the Loan Documents, payments and prepayments of the Obligations shall be applied first to fees, second to accrued interest then due and payable on the Outstanding Amount of Revolving Loans and L/C Obligations, and then to the remaining Obligations in the order and manner as Borrower may direct.

(d) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully the Obligations, or if a Default or Event of Default exists, any payment or prepayment shall be applied in the following order: (i) to the payment of enforcement expenses incurred by the Administrative Agent and/or Collateral Agent, including Attorney Costs; (ii) to the ratable payment of all other fees, expenses, and indemnities for which the Administrative Agent, Collateral Agent or Lenders have not been paid or reimbursed in accordance with the Loan Documents (as used in this Section 2.10(d)(ii), a “ratable payment” for any Lender, the Administrative Agent or Collateral Agent shall be, on

any date of determination, that proportion which the portion of the total fees, expenses, and indemnities owed to such Lender, the Administrative Agent or the Collateral Agent bears to the total aggregate fees and indemnities owed to all Lenders and the Administrative Agent and Collateral Agent on such date of determination); (iii) to the ratable payment of accrued and unpaid interest on the Outstanding Amount of Revolving Loans, Outstanding L/C Obligations, the Outstanding Amount of Obligations under Lender Hedging Agreements and the Outstanding Amount of Obligations under Banking Service Obligations; and (iv) to the payment of the remaining Obligations, if any, in the order and manner the Required Lenders deem appropriate.

(e) Unless the Borrower or any Lender has notified the Administrative Agent prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that the Borrower or such Lender, as the case may be, will not make such payment, the Administrative Agent may assume that the Borrower or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then:

(i) if the Borrower failed to make such payment, each Lender shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds, at the Federal Funds Rate from time to time in effect; and

(ii) if any Lender failed to make such payment, such Lender shall forthwith on demand pay to the Administrative Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Administrative Agent to the Borrower to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to the Federal Funds Rate from time to time in effect. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Revolving Loan, included in the applicable Borrowing. If such Lender does not pay such amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent may make a demand therefor upon the Borrower, and the Borrower shall pay such amount to the Administrative Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Revolving Commitment or to prejudice any rights which the Administrative Agent or the Borrower may have against any Lender as a result of any default by such Lender hereunder.

A notice of the Administrative Agent to any Lender with respect to any amount owing under this subsection (e) shall be conclusive, absent manifest error.

(f) If any Lender makes available to the Administrative Agent funds for any Revolving Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and the conditions to the applicable Borrowing set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(g) The obligations of the Lenders hereunder to make Revolving Loans are several and not joint. The failure of any Lender to make any Revolving Loan on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Revolving Loan or purchase its participation.

(h) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Revolving Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Revolving Loan in any particular place or manner.

2.11 Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Revolving Loans made by it, or the participations in the L/C Obligations, any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Revolving Loans made by them, and/or such subparticipations in the participations in L/C Obligations held by them, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Revolving Loan or such participations, as the case may be, pro rata with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by Law, exercise all its rights of payment (including the right of set-off, but subject to Section 10.09) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

2.12 Pari Passu Lien Securing Lender Hedging Agreements and Banking Service Obligations. All Obligations arising under the Loan Documents, including, without limitation, Obligations under this Agreement, Obligations under any Lender Hedging Agreement (but not Indebtedness of the Borrower or any Subsidiary owing to any non-Lender or non-Lender Affiliate which enters into a Swap Contract with the Borrower or any Subsidiary of the Borrower), and Obligations under any Banking Service Obligation shall be secured pari passu by the Collateral. No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any such Lender Hedging Agreement or Banking Service Obligation.

2.13 Letters of Credit.

(a) The Letter of Credit Commitment.

(i) Subject to the terms and conditions set forth herein, (A) the L/C Issuer agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.13, (1) from time to time on any Business Day during the period from the Second Amended and Restated Closing Date until the Letter of Credit Expiration Date, to issue Letters of Credit for the account of the Borrower or any of its Subsidiaries, and to amend or renew Letters of Credit previously issued by it, in accordance with subsection (b) below, and (2) to honor drafts under the Letters of Credit; and (B) the Lenders severally agree to participate in Letters of Credit issued for the account of the Borrower and its Subsidiaries; provided that the L/C Issuer shall not be obligated to make any L/C Credit Extension with respect to any Letter of Credit, and no Lender shall be obligated to participate in any Letter of Credit, if as of the date of such L/C Credit Extension, (w) the Outstanding Amount of all L/C Obligations and all Revolving Loans would exceed the Aggregate Revolving Commitment, (y) the aggregate Outstanding Amount of the Revolving Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations would exceed such Lender’s Revolving Commitment, or (z) the Outstanding Amount of the L/C Obligations would exceed the Letter of Credit Sublimit. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. The Existing Letters of Credit shall be deemed to have been issued pursuant hereto, and from and after the Second Amended and Restated Closing Date shall be subject to and governed by the terms and conditions hereof.

(ii) The L/C Issuer shall be under no obligation to issue any Letter of Credit if:

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

(B) subject to Section 2.13(b)(iii), the expiry date of such requested Letter of Credit would occur more than twelve months after the date of issuance or last renewal, unless the Required Lenders have approved such expiry date;

(C) the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless all the Lenders have approved such expiry date;

(D) the issuance of such Letter of Credit would violate one or more policies of the L/C Issuer generally applicable to all borrowers; or

(E) such Letter of Credit is in a face amount less than $100,000, or is to be used for a purpose other than as described in Section 6.12 or is denominated in a currency other than Dollars.

(iii) The L/C Issuer shall be under no obligation to amend any Letter of Credit if (A) the L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

(b) Procedures for Issuance and Amendment of Letters of Credit; Evergreen Letters of Credit.

(i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to the L/C Issuer (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of the Borrower. Such Letter of Credit Application must be received by the L/C Issuer and the Administrative Agent not later than 11:00 a.m., New York time, at least two Business Days (or such later date and time as the L/C Issuer may agree in a particular instance in its sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the L/C Issuer may require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may require.

(ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Upon receipt by the L/C Issuer of confirmation from the Administrative Agent that the requested issuance or amendment is permitted in accordance with the terms hereof, then, subject to the terms and conditions hereof, the L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with the L/C Issuer’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the L/C Issuer a participation in such Letter of Credit in an amount equal to the product of such Lender’s Pro Rata Share times the amount of such Letter of Credit.

(iii) If the Borrower so requests in any applicable Letter of Credit Application, the L/C Issuer may, in it sole and absolute discretion, agree to issue a Letter of Credit that has automatic renewal provisions (each, an “Evergreen Letter of Credit”); provided that any such

Evergreen Letter of Credit must permit the L/C Issuer to prevent any such renewal at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Nonrenewal Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the L/C Issuer, the Borrower shall not be required to make a specific request to the L/C Issuer for any such renewal. Once an Evergreen Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the renewal of such Letter of Credit at any time to a date not later than the Letter of Credit Expiration Date; provided, however, that the L/C Issuer shall not permit any such renewal if it has received notice at least five Business Days immediately preceding the Nonrenewal Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such renewal or (2) from any Lender stating that one or more of the applicable conditions specified in Section 4.03 is not then satisfied and directing the L/C Issuer not to permit such renewal. Notwithstanding anything to the contrary contained herein, the L/C Issuer shall have no obligation to permit the renewal of any Evergreen Letter of Credit at any time.

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

(i) Upon any drawing under any Letter of Credit, the L/C Issuer shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m., New York time, on the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the L/C Issuer by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested a Borrowing under the Revolver Facility of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Revolving Commitment and the conditions set forth in Section 4.03 (other than the delivery of a Borrowing Notice). Any notice given by the L/C Issuer or the Administrative Agent pursuant to this Section 2.13(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender (including the Lender acting as L/C Issuer) shall upon any notice pursuant to Section 2.13(c)(i) make funds available to the Administrative Agent for the account of the L/C Issuer at the Administrative Agent’s Office in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 11:00 a.m., New York time, on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.13(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Revolving Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the L/C Issuer.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of Base Rate Revolving Loans because the conditions set forth in Section 4.03 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.13(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.13.

(iv) Until each Lender funds its Revolving Loan or L/C Advance pursuant to this Section 2.13(c) to reimburse the L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make Revolving Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.13(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the L/C Issuer, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default or Event of Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

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

(d) Repayment of Participations.

(i) At any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.13(c), if the Administrative Agent receives for the account of the L/C Issuer any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of cash Collateral applied thereto by the Administrative Agent), or any payment of interest thereon, the Administrative Agent will distribute to such Lender its Pro Rata Share thereof in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.13(c)(i) is required to be returned, each Lender shall pay to the

Administrative Agent for the account of the L/C Issuer its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

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

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

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

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

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

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

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

The Borrower shall also promptly examine any documents sent to the L/C Issuer in connection with a drawing under a Letter of Credit after the L/C Issuer provides copies of such documents to the Borrower and the Borrower shall immediately notify the L/C Issuer of any objection or claim of noncompliance of such documents with the requirements of the Letter of Credit.

(f) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. No Agent-Related Person nor any of the respective correspondents, participants or assignees of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable, (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. No Agent-Related Person, nor any of the respective correspondents, participants or assignees of the L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.13(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations (in an amount equal to such Outstanding Amount). The Borrower hereby grants the Administrative Agent and Collateral Agent, for the benefit of the L/C Issuer and the Lenders, a Lien on all such cash and deposit accounts at any Lender.

(h) Applicability of ISP98. Unless otherwise expressly agreed by the L/C Issuer and the Borrower when a Letter of Credit is issued, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each Letter of Credit.

(i) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share a letter of credit fee for each Letter of Credit issued equal to the Applicable Rate times the actual daily undrawn amount under each Letter of Credit. Such fee for each Letter of Credit shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, and on the Letter of Credit Expiration Date.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a fronting fee in an amount with respect to each Letter of Credit issued equal to the greater of (i) $500 and (ii) 1/8 of 1% calculated on the face amount thereof. In addition, the Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of credit as from time to time in effect. Such fees and charges are due and payable on demand and are nonrefundable.

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

ARTICLE III.
TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Any and all payments by the Borrower to or for the account of the Administrative Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto; excluding, in the case of the Administrative Agent and each Lender, (i) taxes imposed on or measured by its net income, and franchise taxes (including the Texas franchise tax) imposed on it (in lieu of net income taxes), by the United States or any state or political subdivision thereof, or by the jurisdiction (or any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender, as the case may be, is organized, is or should be qualified to do business or maintains its Lending Office, (ii) any branch profits taxes imposed by the United States of America or any similar tax imposed by any other jurisdiction described in clause (i) above, (iii) in the case of a Foreign Lender, any withholding tax that is imposed on amounts payable to such Foreign Lender at the time such Foreign Lender becomes a party to this Agreement (or designates a new lending office) or is attributable to such Foreign Lender’s failure to comply with Section 3.01(f), except to the extent that such Foreign Lender (or its assignor, if any) was entitled, at the time of designation of a new lending office (or assignment), to receive additional amounts from the Borrower with respect to such withholding tax pursuant to this Section 3.01(a) and which withholding tax may not be eliminated by complying with Section 3.01(f), and (iv) any backup withholding tax required to be withheld or paid pursuant to Section 3406 of the Code (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, (1) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), each of the Administrative Agent and such Lender receives an amount equal to the sum it would have received had no such deductions been made, (2) the Borrower shall make such deductions, (3) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (4) within 30 days after the date of such payment, the Borrower shall furnish to the Administrative Agent (which shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

(b) In addition, the Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from

any payment made under any Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c) If the Borrower shall be required to deduct or pay any Taxes or Other Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, the Borrower shall also pay to the Administrative Agent (for the account of such Lender) or to such Lender, at the time interest is paid, such additional amount that such Lender specifies as necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on or measured by net income) such Lender would have received if such Taxes or Other Taxes had not been imposed.

(d) The Borrower agrees to indemnify the Administrative Agent and each Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by the Administrative Agent and such Lender, (ii) amounts payable under Section 3.01(c) and (iii) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payment under this subsection (d) shall be made within 30 days after the date the Lender or the Administrative Agent makes a demand therefor.

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

(f) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document 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 or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law, or reasonably requested by Borrower, as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party;

(ii) duly completed copies of Internal Revenue Service Form W-8ECI;

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN; or

(iv) any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower to determine the withholding or deduction required to be made.

3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or materially restricts the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period thereof, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay interest on the amount so prepaid or converted. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the reasonable judgment of such Lender, otherwise be materially disadvantageous to such Lender.

3.03 Inability to Determine Rates. If the Administrative Agent determines in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the applicable offshore Dollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, or adequate and reasonable means do not exist for determining the Eurodollar Rate for such Eurodollar Rate Loan, or (b) if the Required Lenders determine and notify the Administrative Agent that the Eurodollar Rate for such Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such Eurodollar Rate Loan, then the Administrative Agent will promptly notify the Borrower and all Lenders. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing, conversion or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

3.04 Increased Cost and Reduced Return; Capital Adequacy; Reserves on Eurodollar Rate Loans.

(a) If any Lender or the L/C Issuer determines that as a result of a Change in Law, or such Lender’s or L/C Issuer’s compliance therewith, there shall be any increase in the cost to such Lender or

L/C Issuer of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining any Letter of Credit, or a reduction in the amount received or receivable by such Lender or L/C Issuer in connection with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.01 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which such Lender or L/C Issuer is organized or has its Lending Office, and (iii) reserve requirements contemplated by Section 3.04(c) utilized, as to Eurodollar Rate Loans, in the determination of the Eurodollar Rate), then from time to time upon demand of such Lender or L/C Issuer (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender or L/C Issuer, as the case may be, such additional amounts as will compensate such Lender or L/C Issuer for such increased cost or reduction.

(b) If any Lender determines a Change in Law has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital, then from time to time upon demand of such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

(c) The Borrower shall pay to each Lender, as long as such Lender shall be required under regulations of the Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional costs on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Revolving Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Revolving Loan; provided the Borrower shall have received at least 10 days’ prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give notice 10 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 10 days from receipt of such notice.

3.05 Funding Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Revolving Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Revolving Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

(b) any failure by the Borrower (for a reason other than the failure of such Lender to make a Revolving Loan) to prepay, borrow, continue or convert any Revolving Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower; including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Revolving Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Revolving Loan by a matching deposit or other borrowing in the applicable offshore Dollar interbank market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06 Matters Applicable to all Requests for Compensation. A certificate of the Administrative Agent or any Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Administrative Agent or such Lender may use any reasonable averaging and attribution methods.

3.07 Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Aggregate Revolving Commitment and payment in full of all the other Obligations.

3.08 Mitigation Obligations. If any Lender or L/C Issuer requests compensation under Section 3.04, or if the Borrower is required to pay any additional amount to any Lender, L/C Issuer or any Governmental Authority for the account of any Lender or L/C Issuer, as applicable, pursuant to Section 3.01, then such Lender or L/C Issuer shall use reasonable efforts to designate a different Lending Office for funding or booking its Revolving Loans or issuing Letters of Credit hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender or L/C Issuer, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or Section 3.04, as the case may be, in the future and (ii) would not subject such Lender or L/C Issuer to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or L/C Issuer. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender or L/C Issuer in connection with any such designation or assignment.

The Borrower will not repay any principal, interest or other indebtedness in respect of the Subordinated Indebtedness, or make any redemption or acquisition for value or defeasance, refinancing or exchange thereof or therefore, or make any payments in contravention of the applicable Subordination Agreement; provided, however, with respect to all Subordinated Indebtedness up to $1,000,000 principal may be repaid or prepaid so long as no Default or Event of Default shall have occurred and be continuing or would result from such payment and Borrower shall so certify to Administrative Agent in writing prior to any such payment.

ARTICLE IX.
ADMINISTRATIVE AGENT

9.01 Appointment and Authorization of Agents; Lender Hedging Agreements. (a) Each Lender and the L/C Issuer hereby irrevocably (subject to Section 9.10) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, 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. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent or Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Required Lenders to act for the L/C Issuer with respect thereto; provided, however, that the L/C Issuer shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article IX with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article IX included the L/C Issuer with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the L/C Issuer.

(c) To the extent any Lender or any Affiliate of a Lender is a party to a Lender Hedging Agreement and accepts the benefits of the Liens in the Collateral arising pursuant to the Collateral Documents, such Lender (for itself and on behalf of any such Affiliates) shall be deemed (i) to appoint the Administrative Agent and Collateral Agent, as its nominee and agent, to act for and on behalf of such Lender or Affiliate thereof in connection with the Collateral Documents and (ii) to be bound by the terms of this Article IX.

9.02 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents (including the Collateral Agent), employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. Neither the Administrative Agent nor the Collateral Agent shall be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

9.03 Default; Collateral. (a) Upon the occurrence and continuance of a Default or Event of Default, the Lenders agree to promptly confer in order that Required Lenders or the Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from Required Lenders. All rights of action under the Loan Documents and all right to the Collateral, if any, hereunder may be enforced by the Administrative Agent (or the Collateral Agent) and any suit or proceeding instituted by the Administrative Agent (or the Collateral Agent) in furtherance of such enforcement shall be brought in its name as the Administrative Agent (or the Collateral Agent) without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders (and, with respect to Lender Hedging Agreements, Affiliates, if applicable) subject to the expenses of the Administrative Agent and/or Collateral Agent. In actions with respect to any property of the Borrower or any other Obligor, the Administrative Agent (and the Collateral Agent) is acting for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreement, Affiliates, if applicable). Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of Borrower to the Obligations shall be construed as being for the ratable benefit of each Lender (and, with respect to Lender Hedging Agreement, Affiliates, if applicable).

(b) Each Lender authorizes and directs the Administrative Agent and Collateral Agent to enter into the Collateral Documents on behalf of and for the benefit of the Lenders (and, with respect to Lender Hedging Agreements, Affiliates, if applicable)(or if previously entered into, hereby ratifies the Administrative Agent’s (and the Collateral Agent’s) previously entering into such agreements and Collateral Documents).

(c) Except to the extent unanimity (or other percentage set forth in Section 10.1) is required hereunder, each Lender agrees that any action taken by the Required Lenders in accordance with the provisions of the Loan Documents, and the exercise by the Required Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders.

(d) The Administrative Agent and Collateral Agent are each hereby authorized on behalf of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Collateral or Collateral Documents which may be necessary to

perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Collateral Documents.

(e) Neither the Administrative Agent nor the Collateral Agent shall have any obligation whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned by any Obligor or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent and/or Collateral Agent herein or pursuant to any Collateral Document have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the Rights granted or available to the Administrative Agent or Collateral Agent in this Section 9.03 or in any of the Collateral Documents; it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Administrative Agent may act in any manner it may deem appropriate, in its sole discretion, given the Administrative Agent’s own interest in the Collateral as one of the Lenders and that the Administrative Agent shall have no duty or liability whatsoever to any Lender, other than to act without gross negligence or willful misconduct and the same shall apply to the Collateral Agent so long as the Administrative Agent is also the Collateral Agent.

(f) The Lenders hereby irrevocably authorize the Administrative Agent and/or Collateral Agent, at its option and in its discretion, to release any Lien granted to or held by the Administrative Agent or Collateral Agent upon any Collateral: (i) constituting property in which no Obligor owned an interest at the time the Lien was granted or at any time thereafter; (ii) constituting property leased to an Obligor under a lease which has expired or been terminated in a transaction permitted under the Loan Document or is about to expire and which has not been, and is not intended by such Obligor to be, renewed; and (iii) consisting of an instrument evidencing Indebtedness pledged to the Administrative Agent or Collateral Agent (for the benefit of the Lenders), if the Indebtedness evidenced thereby has been paid in full. In addition, the Lenders irrevocably authorize the Administrative Agent and Collateral Agent to release Liens upon Collateral as contemplated in Section 10.01(c) or (d), or if approved, authorized, or ratified in writing by the requisite Lenders. Upon request by the Administrative Agent ((or the Collateral Agent) at any time, the Lenders will confirm in writing the Administrative Agent’s (or the Collateral Agent’s) authority to release particular types or items of Collateral pursuant to this Section 9.03.

(g) In furtherance of the authorizations set forth in this Section 9.03, each Lender hereby irrevocably appoints the Administrative Agent and Collateral Agent its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Collateral Documents (including, without limitation, any appointments of substitute trustees under any Collateral Documents), (ii) to take action with respect to the Collateral and Collateral Documents to perfect, maintain, and preserve Lenders’ Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Collateral to the extent authorized in paragraph (f) hereof. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s and Collateral Agent’s power, as attorney, relative to the Collateral matters described in this Section 9.03. The powers and authorities herein conferred on the Administrative Agent and Collateral Agent may be exercised by the Administrative Agent or Collateral Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of the Administrative Agent pursuant to a valid power of attorney) or is an officer of the Collateral Agent (or any Person acting on behalf of the Collateral Agent pursuant to a valid power of attorney). The power of attorney conferred by this Section 9.03(g) to the Administrative Agent and Collateral Agent is granted for valuable consideration and is coupled with an interest and is

irrevocable so long as the Obligations, or any part thereof, shall remain unpaid or the Lenders are obligated to make any Borrowings under the Loan Documents.

9.04 Liability of Agents. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for the creation, perfection or priority of any Liens purported to be created by any of the Loan Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Loan Document, or for any failure of any Loan Party or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant 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 or any Affiliate thereof.

9.05 Reliance by Administrative Agent. (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, facsimile, telex or telephone message, statement or other document or conversation reasonably 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 counsel to any Loan Party), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and participants. Where this Agreement expressly permits or prohibits an action unless the Required Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the Lenders.

(b) For purposes of determining compliance with the conditions specified in Section 4.01, each Lender that has funded its Pro Rata Share of the Borrowing(s) on the Second Amended and Restated Closing Date (or, if there is no Borrowing made on such date, each Lender other than Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

9.06 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written 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.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Required Lenders in accordance with Article VIII; provided, however, that unless and until the Administrative Agent has received any such direction, 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 or in the best interest of the Lenders.

9.07 Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person 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 investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent Related Person.

9.08 Indemnification of Agents. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities resulting from such Person’s gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal

proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section shall survive termination of the Revolving Commitments, the payment of all Obligations hereunder and the resignation or replacement of the Administrative Agent.

9.09 Administrative Agent in its Individual Capacity. Royal Bank and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan Parties and their respective Affiliates as though Royal Bank were not the Administrative Agent, Collateral Agent or the L/C Issuer hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Royal Bank or its Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of such Loan Party or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Revolving Loans, Royal Bank shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent, Collateral Agent or the L/C Issuer, and the terms “Lender” and “Lenders” include Royal Bank in its individual capacity.

9.10 Successor Administrative Agent and Collateral Agent. The Administrative Agent may resign as Administrative Agent and Collateral Agent upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the Administrative Agent resigns under this Agreement, the Required Lenders shall appoint from among the Lenders a successor administrative agent and collateral agent for the Lenders which successor administrative agent and collateral agent shall be consented to by the Borrower at all times other than during the existence of an Event of Default (which consent of the Borrower shall not be unreasonably withheld or delayed). If no successor administrative agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders and the Borrower, a successor administrative agent from among the Lenders, who shall also succeed to the role of collateral agent. Upon the acceptance of its appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor administrative agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article IX and Sections 10.04 and 10.13 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. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 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 perform all of the duties of the Administrative Agent and Collateral Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

9.11 Other Agents; Arrangers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “documentation agent,” any other type of agent (other than the Administrative Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not

relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

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

(i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Revolving Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under Sections 2.13(i) and (j), 2.07 10.04 and 10.05) allowed in such judicial proceeding; and

(ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.07, 10.04 and 10.05.

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

(vii) amend this Section, or Section 2.11, or any provision herein providing for unanimous consent or other action by all the Lenders;

and, provided further: (i) no amendment, waiver or consent shall, unless in writing and signed by the L/C Issuer in addition to the Required Lenders or all the Lenders, as the case may be, and the Administrative Agent, affect the rights or duties of the L/C Issuer under this Agreement or any Letter of Credit Application relating to any Letter of Credit issued or to be issued by it; (ii) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Required Lenders or all the Lenders, as the case may be, affect the rights or duties of the Administrative Agent under this Agreement or any other Loan Document; and (iii) the Agent/Arranger Fee Letter may be amended, or rights or privileges thereunder waived, in a writing executed only by the parties thereto.

(b) Any amendment to any Loan Document which purports to (i) decrease the amount of any mandatory prepayment or commitment reduction required by Section 2.03 or (ii) change this Section

10.01(b), must be by an instrument in writing executed by Borrower, the Administrative Agent, and the Required Lenders.

(c) Upon any sale, transfer or Disposition of Collateral which is permitted pursuant to the Loan Documents, and upon 10 Business Days’ prior written request by the Borrower (which request must be accompanied by (i) true and correct copies of all material documents of transfer or Disposition, including any contract of sale, (ii) a preliminary closing statement and instructions to the title company, if any, (iii) all requested release instruments in form and substance satisfactory to the Administrative Agent and (iv) if required, written consent of the requisite Lenders), the Administrative Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents as may be necessary to evidence the release of Liens granted to the Administrative Agent for the benefit of the Lenders pursuant hereto in such Collateral. The Administrative Agent shall not be required to execute any release instruments on terms which, in the Administrative Agent’s opinion, would expose the Administrative Agent to liability or create any obligation or entail any consequence other than the release of Liens without recourse or warranty. No such release shall impair the Administrative Agent’s Lien on the proceeds of sale of such Collateral.

(d) If all outstanding Revolving Loans and other Obligations (other than contingent indemnity obligations) have been indefeasibly paid in full (or, with respect to L/C Obligations, Cash Collateralized) and the Revolving Commitments have terminated or have been reduced to zero, and, subject to Section 10.01(e) all Lender Hedging Agreement have terminated, the Administrative Agent agrees to, and the Lenders hereby instruct the Administrative Agent to, at the Borrower’s expense, execute and authorize such releases of the Collateral Documents as the Borrower shall reasonably request and this Agreement shall be deemed terminated except that such termination shall not relieve the Borrower of any obligation to make any payments to the Administrative Agent or any Lender required by any Loan Document to the extent accruing, or relating to an event occurring, prior to such termination.

(e) Notwithstanding any provision herein to the contrary, if the Revolving Commitments have been terminated, and the only outstanding Obligations (other than contingent indemnity obligations and L/C Obligations that are Cash Collateralized) are amounts owed pursuant to one or more Lender Hedging Agreements, the Administrative Agent will, and is hereby authorized to, (A) release the Liens created under the Loan Documents and (B) release all Guaranties of the Borrower; provided, that contemporaneously with such release, (i) the Borrower (and, if applicable, the Subsidiary that is a party to such Lender Hedging Agreements) (A) executes a margin agreement in form and substance acceptable to such Lender(s) (or its Affiliates) that are parties to such Lender Hedging Agreements (the “Lender Counterparties”) and (B), if required, provides collateral in the form of cash or a letter of credit having an aggregate value acceptable to such Lender Counterparties, and (ii) if such Lender Hedging Agreement is executed by a Subsidiary of the Borrower and the Borrower is not a party thereto, the Borrower executes a guaranty covering such Subsidiary’s obligations thereunder, such guaranty to be in form and substance satisfactory to the Lender Counterparties. Any release under this Section 10.01(e) must be in writing and signed by the Administrative Agent.

10.02 Notices and Other Communications; Facsimile Copies.

(a) General. Unless otherwise expressly provided herein, all notices and other communications provided for hereunder and under the other Loan Documents shall be in writing (including by facsimile transmission) and mailed, faxed or delivered, to the address, facsimile number or

Any notice or other communication permitted to be given, made or confirmed by telephone hereunder shall be given, made or confirmed by means of a telephone call to the intended recipient at the number specified in accordance with this Section, it being understood and agreed that a voicemail message shall in no event be effective as a notice, communication or confirmation hereunder.

(b) Effectiveness of Facsimile Documents and Signatures. Loan Documents may be transmitted and/or signed by facsimile. The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually-signed originals and shall be binding on all Loan Parties, the Administrative Agent and the Lenders. The Administrative Agent may also require that any such documents and signatures be confirmed by a manually-signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

(c) Limited Use of Electronic Mail. Electronic mail and internet and intranet websites may be used only to distribute routine communications, such as financial statements and other information, and to distribute Loan Documents for execution by the parties thereto, and shall not be recognized hereunder for any other purpose.

(d) Reliance by Administrative Agent, L/C Issuer and Lenders. The Administrative Agent, L/C Issuer and the Lenders shall be entitled to rely and act upon any notices (including telephonic Borrowing Notices) purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify each Agent-Related Person and each Lender from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and other communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording.

10.03 No Waiver; Cumulative Remedies. No failure by any Lender, the Administrative Agent or the Collateral Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and

privileges herein or therein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by Law.

10.04 Attorney Costs; Expenses and Taxes. The Borrower agrees (a) to pay or reimburse the Arranger, the Administrative Agent and Collateral Agent for all costs and expenses associated with the due diligence and background investigation undertaken in connection with this Agreement and incurred in connection with the development, preparation, negotiation, syndication, administration and execution of this Agreement and the other Loan Documents, including the filing, recording, refiling or rerecording of any pledge agreement and any Security Agreement and/or any UCC financing statements relating thereto and all amendments, supplements and modifications to any thereof and any and all other documents or instruments of further assurance required to be filed or recorded or refiled or rerecorded by the terms hereof or of any mortgage, any pledge agreement or any security agreement, and any amendment, waiver, consent or other modification of the provisions hereof and thereof (whether or not the transactions contemplated hereby or thereby are consummated), and the consummation and administration of the transactions contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or reimburse the Administrative Agent, Collateral Agent and each Lender for all costs and expenses incurred in connection with the enforcement, attempted enforcement, or preservation of any rights or remedies under this Agreement or the other Loan Documents (including all such costs and expenses incurred during any workout or restructuring in respect of the Obligations and during any legal proceeding, including any proceeding under any Debtor Relief Law), including all Attorney Costs. The foregoing costs and expenses shall include all search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by the Administrative Agent and Collateral Agent and the cost of independent public accountants and other outside experts retained by the Administrative Agent or any Lender. The agreements in this Section shall survive the termination of the Revolving Commitments and repayment of all the other Obligations.

10.05 Indemnification. Whether or not the transactions contemplated hereby are consummated, the Borrower and each Guarantor (by execution of a Guaranty), jointly and severally, agrees to indemnify, save and hold harmless each Agent-Related Person, the Administrative Agent, the Collateral Agent, the Arranger, each Lender, the L/C Issuer and their respective Affiliates, directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Indemnitees”) from and against: (a) any and all claims, demands, actions or causes of action that are asserted against any Indemnitee by any Person (other than the Administrative Agent or any Lender) relating directly or indirectly to a claim, demand, action or cause of action that such Person asserts or may assert against any Loan Party, any Affiliate of any Loan Party or any of their respective officers or directors, arising out of or relating to, the Loan Documents, the Revolving Commitments, the use or contemplated use of the proceeds of any Revolving Loans, or the relationship of any Loan Party, the Arranger, the Administrative Agent, the Collateral Agent, the Lenders and the L/C Issuer under this Agreement or any other Loan Document; (b) any and all claims, demands, actions or causes of action that may at any time (including at any time following repayment of the Obligations and the resignation of the Administrative Agent or the replacement of any Lender) be asserted or imposed against any Indemnitee by any Person or by the Borrower or any other Loan Party, arising out of or relating to, the Loan Documents, the Revolving Commitments, the use or contemplated use of the proceeds of any Revolving Loans, or the relationship of any Loan Party, the Arranger, the Administrative Agent, the Collateral Agent, the Lenders and the L/C Issuer under this Agreement or any other Loan Document; (c) without limiting the foregoing, any and all claims, demands, actions or causes of action, judgments and orders, penalties and fines that are asserted or imposed against any Indemnitee, (i) under the application of any Environmental Law applicable to the Borrower or any of its Subsidiaries or any of their properties or assets, including the treatment or disposal

of Hazardous Substances on any of their properties or assets, (ii) as a result of the breach or non-compliance by the Borrower or any Subsidiary with any Environmental Law applicable to the Borrower or any Subsidiary, (iii) due to past ownership by the Borrower or any Subsidiary of any of their properties or assets or past activity on any of their properties or assets which, though lawful and fully permissible at the time, could result in present liability, (iv) due to the presence, use, storage, treatment or disposal of Hazardous Substances on or under, or the escape, seepage, leakage, spillage, discharge, emission or Release from, any of the properties owned or operated by the Borrower or any Subsidiary (including any liability asserted or arising under any Environmental Law), regardless of whether caused by, or within the control of, the Borrower or such Subsidiary, or (v) due to any other environmental, health or safety condition in connection with the Loan Documents; (d) any administrative or investigative proceeding by any Governmental Authority arising out of or related to a claim, demand, action or cause of action described in subsection (a), (b) or (c) above; and (e) any and all liabilities (including liabilities under indemnities), losses, costs, damages or expenses (including Attorney Costs and settlement costs) that any Indemnitee suffers or incurs as a result of the assertion of any foregoing claim, demand, action, cause of action or proceeding, or as a result of the preparation of any defense in connection with any foregoing claim, demand, action, cause of action or proceeding, in all cases, WHETHER OR NOT ARISING OUT OF THE STRICT LIABILITY OR NEGLIGENCE OF AN INDEMNITEE, and whether or not an Indemnitee is a party to such claim, demand, action, cause of action or proceeding (all the foregoing, collectively, the “Indemnified Liabilities”); provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, losses, costs, damages or expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. The agreements in this Section shall survive and continue for the benefit of the Indemnitees at all times after the Borrower’s acceptance of the Lenders’ Revolving Commitments under this Agreement, whether or not the Second Amended and Restated Closing Date shall occur and shall survive the termination of the Revolving Commitments and repayment of all the other Obligations.

10.06 Payments Set Aside. To the extent that the Borrower makes a payment to the Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such set-off or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect.

10.07 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way

of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitment and the Revolving Loans (including for purposes of this subsection (b), participations in L/C Obligations) at the time owing to it); provided that:

except in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitment and the Revolving Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Revolving Commitment (which for this purpose includes Revolving Loans outstanding thereunder) or, if the applicable Revolving Commitment is not then in effect, the outstanding principal balance of the Revolving Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $1,000,000, unless each of the Administrative Agent, L/C Issuer and, so long as no Default or Event of Default has occurred and is continuing, the Borrower otherwise consent (Borrower’s consent not to be unreasonably withheld, conditioned or delayed);

(i) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Revolving Loans and/or the Revolving Commitment assigned; and

(ii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, the assigning Lender or the assignee shall pay the Administrative Agent a processing and recordation fee of $3,500 (which the Administrative Agent may waive or reduce in its sole discretion), and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Details Form.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.07, 10.04 and 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Commitments of, and principal amounts of the Revolving Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower, the Administrative Agent or the L/C Issuer, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Commitment and/or the Revolving Loans (including such Lender’s participation in L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that would (i) postpone any date upon which any payment of money is scheduled to be paid to such Participant, (ii) reduce the principal, interest, fees or other amounts payable to such Participant, or (iii) extend the Maturity Date. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.09 as though it were a Lender; provided such Participant agrees to be subject to Section 2.11 and Section 3.08 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01 as though it were a Lender.

(f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Revolver Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) If the consent of the Borrower to an assignment or to an Eligible Assignee is required hereunder (including a consent to an assignment which does not meet the minimum assignment threshold

specified in clause (i) of the proviso to the first sentence of Section 10.07(b)), the Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth Business Day.

(h) Notwithstanding anything to the contrary contained herein, if at any time Royal Bank assigns all of its Revolving Commitment and Revolving Loans pursuant to subsection (b) above, Royal Bank may, (i) upon 30 days’ notice to the Borrower and the Lenders, resign as L/C Issuer. In the event of any such resignation as L/C Issuer, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Royal Bank as L/C Issuer. Royal Bank shall retain all the rights and obligations of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund participations in Unreimbursed Amounts pursuant to Section 2.13(c)).

10.08 Confidentiality. Each Lender agrees that it will not disclose without the prior consent of the Borrower (other than to directors, officers, employees, auditors, accountants, counsel or other professional advisors of the Administrative Agent or any Lender) any information with respect to the Borrower or its Subsidiaries, which is furnished pursuant to this Agreement and which (i) the Borrower in good faith considers to be confidential and (ii) is either clearly marked confidential or is designated by the Borrower to the Administrative Agent or the Lenders in writing as confidential; provided that any Lender may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or federal regulatory body having or claiming to have jurisdiction over such Lender or submitted to or required by the Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, (c) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (d) in order to comply with any Law, order, regulation or ruling applicable to such Lender, (e) to any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement; provided that such Eligible Assignee or Participant or prospective Eligible Assignee or Participant executes an agreement containing provisions substantially similar to those contained in this Section 10.08, (f) in connection with the exercise of any remedy by such Lender following an Event of Default pertaining to the Loan Documents, (g) in connection with any litigation involving such Lender pertaining to the Loan Documents, (h) to any Lender or the Administrative Agent, or (i) to any Affiliate of any Lender (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and obligated to keep such information confidential).

10.09 Set-off. In addition to any rights and remedies of the Lenders provided by Law, upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, without prior notice to the Borrower or any other Loan Party, any such notice being waived by the Borrower (on its own behalf and on behalf of each Loan Party) to the fullest extent permitted by Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to the Administrative Agent and the Lenders, now or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured. Each Lender agrees promptly

to notify the Borrower and the Administrative Agent after any such set-off and application made by such Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

10.10 Interest Rate Limitation. Regardless of any provision contained in any Loan Document, neither the Administrative Agent nor any Lender shall ever be entitled to contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the Obligations, any amount in excess of the Maximum Rate, and, if any Lender ever does so, then such excess shall be deemed a partial prepayment of principal and treated hereunder as such and any remaining excess shall be refunded to the Borrower. In determining if the interest paid or payable exceeds the Maximum Rate, the Borrower and the Lenders shall, to the maximum extent permitted under applicable Law, (a) treat all Borrowings as but a single extension of credit (and the Lenders and the Borrower agree that such is the case and that provision herein for multiple Borrowings is for convenience only), (b) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Obligations. However, if the Obligations are paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Amount, the Lenders shall refund such excess, and, in such event, the Lenders shall not, to the extent permitted by Law, be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Amount. To the extent the Laws of the State of Texas are applicable for purposes of determining the “Maximum Rate” or the “Maximum Amount,” then those terms mean the “weekly ceiling” from time to time in effect under Texas Finance Code § 303.001, as limited by Texas Finance Code § 303.009. The Borrower agrees that Chapter 346 of the Texas Finance Code, as amended (which regulates certain revolving credit loan accounts and revolving tri-party accounts), does not apply to the Obligations.

10.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.12 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

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

10.14 Severability. Any provision of this Agreement and the other Loan Documents to which the Borrower is a party 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 thereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.15 Replacement of Lenders. If (i) any Lender fails or refuses to consent to any requested amendment or waiver pursuant to Section 10.01 and the Required Lenders have approved such requested amendment or waiver, (ii) any Lender requests compensation under Section 3.04, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, (iii) any Lender is in breach of any of its obligations under this Agreement or (iv) if any other circumstance exists hereunder that gives the Borrower the right to replace a Lender as a party hereto, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.07), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(a) the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 10.07(b)(iii);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Revolving Loans, L/C Advances, L/C Borrowings, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05 as though such replacement were a repayment and not as assignment) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) such payment being at par, with no premium or discount;

(c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter; and

(d) such assignment does not conflict with applicable Laws.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

10.16 Governing Law.

(a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF TEXAS APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER UNITED STATES FEDERAL LAW.

(b) EACH LOAN PARTY AND OTHER PARTY HERETO, AND EACH GUARANTOR, BY EXECUTION OF A GUARANTY, AGREES AS TO THIS SECTION 10.16(b). ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS SITTING IN HARRIS COUNTY OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, AND BY EXECUTION OF A GUARANTY, EACH GUARANTOR CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, EACH GUARANTOR, THE ADMINISTRATIVE AGENT AND EACH LENDER (1) IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO, AND (2) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS FOR NOTICES DESIGNATED HEREIN. THE BORROWER, EACH GUARANTOR, THE ADMINISTRATIVE AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

10.17 Waiver of Right to Trial by Jury, Etc. EACH PARTY TO THIS AGREEMENT AND EACH GUARANTOR, BY EXECUTION OF A GUARANTY, HEREBY (a) EXPRESSLY AND IRREVOCABLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES TO THE LOAN DOCUMENTS OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE LOAN PARTIES TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY; AND (b) EXPRESSLY AND IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH ACTION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; PROVIDED THAT THE WAIVER CONTAINED IN THIS SECTION 10.17(b) SHALL NOT APPLY TO THE EXTENT THAT THE PARTY AGAINST WHOM DAMAGES ARE SOUGHT HAS ENGAGED IN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

10.18 Termination of Commitments Under First Amended and Restated Credit Agreement. As of the Second Amended and Restated Closing Date, the aggregate commitments under the First Amended and Restated Credit Agreement are terminated and the Administrative Agent and the Lenders hereby waive any right to receive prior notice of such termination. Each Lender agrees upon the Second Amended and Restated Closing Date to return to Borrower with reasonable promptness all

“Notes” as defined under the First Amended and Restated Credit Agreement which were delivered by the Borrower in exchange for new Revolver Notes to be issued pursuant to this Agreement.

10.19 No Novations, Etc. To the extent of the aggregate commitment outstanding under the First Amended and Restated Credit Agreement ($25,000,000), nothing contained herein shall be deemed a novation of or a repayment or new advance of any obligation of the Borrower hereunder. Only to the extent of an increase in the Aggregate Revolving Commitment over that amount shall there be deemed to be a new advance by the Lenders to the Borrower under this Agreement. The Indebtedness owing under the First Amended and Restated Credit Agreement is renewed, rearranged, extended and carried forward by this Agreement and all of the liens and security interests securing the “Obligations” as defined in the First Amended and Restated Credit Agreement are carried forward and secure, without interruption or loss or priority, the Obligations under this Agreement.

10.20 USA Patriot Act. Pursuant to the requirements of the USA PATRIOT Act (Title) III of Pub. L.107-56 (signed into law October 26, 2001), each Lender is required to obtain, verify and record information that identifies the Borrower and the Guarantors, which information includes the names and addresses of the Borrower and the Guarantors and other information that will allow each Lender to identify the Borrower and the Guarantors in accordance with said Act.

10.21 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN 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.
