(f)

a Request for Revolving Credit Advance, once delivered to Agent, shall not be revocable by Borrowers and shall constitute a certification by Borrowers as of the date thereof that:

all conditions to the making of Revolving Credit Advances set forth in this Agreement have been satisfied, and shall remain satisfied to the date of such Revolving Credit Advance (both before and immediately after giving effect to such Revolving Credit Advance);

(vi)

there is no Default or Event of Default in existence, and none will exist upon the making of such Revolving Credit Advance (both before and immediately after giving effect to such Revolving Credit Advance); and

Agent, acting on behalf of the Revolving Credit Lenders, may also, at its option, lend under this Section 2.3 upon the telephone or email request of an Authorized Signer of the Borrower Representative to make such requests and, in the event Agent, acting on behalf of the Revolving Credit Lenders, makes any such Advance upon a telephone or email request, an Authorized Signer shall fax or deliver by electronic file to Agent, on the same day as such telephone or email request, an executed Request for Revolving Credit Advance. Each Borrower hereby authorizes Agent to disburse Advances under this Section 2.3 pursuant to the telephone or email instructions of any person purporting to be an Authorized Signer. Notwithstanding the foregoing, Borrowers acknowledge that Borrowers shall bear all risk of loss resulting from disbursements made upon any telephone or email request. Each telephone or email request for an Advance from an Authorized Signer for the Borrower Representative shall constitute a certification by the Borrowers of the matters set forth in the Request for Revolving Credit Advance form as of the date of such requested Advance.

2.4 Disbursement of Advances.

(a) Upon receiving any Request for Revolving Credit Advance from Borrowers under Section 2.3 hereof, Agent shall promptly notify each Revolving Credit Lender by wire, telex or telephone (confirmed by wire, telecopy or telex) of the amount of such Advance being requested and the date such Revolving Credit Advance is to be made by each Revolving Credit Lender in an amount equal to its Revolving Credit Percentage of such Advance. Unless such Revolving Credit Lender’s commitment to make Revolving Credit Advances hereunder shall have been suspended or terminated in accordance with this Agreement, each such Revolving Credit Lender shall make available the amount of its Revolving Credit Percentage of each Revolving Credit Advance in immediately available funds to Agent, as follows:

(i)

for Prime-based Advances, at the office of Agent located at Xxx Xxxxxxx Xxxxxx, Xxxxxxx, Xxxxxxxx 00000, not later than 1:00 p.m. (Detroit time) on the date of such Advance; and

(ii)

for Eurodollar-based Advances, at the Agent’s Correspondent for the account of the Eurodollar Lending Office of the Agent, not later than 12:00 p.m. (the time of the Agent’s Correspondent) on the date of such Advance.

(b) Subject to submission of an executed Request for Revolving Credit Advance by Borrowers without exceptions noted in the compliance certification therein, Agent shall make available to Borrowers the aggregate of the amounts so received by it from the Revolving Credit Lenders in Dollars:

(i)

for Prime-based Advances, not later than 4:00 p.m. (Detroit time) on the date of such Revolving Credit Advance, by credit to an account of Borrowers maintained with Agent or to such other account or third party as Borrowers may reasonably direct in writing, provided such direction is timely given; and

(ii)

for Eurodollar-based Advances, not later than 4:00 p.m. (the time of the Agent’s Correspondent) on the date of such Revolving Credit Advance, by credit to an account of Borrowers maintained with Agent’s Correspondent or to such other account or third party as Borrowers may direct, provided such direction is timely given.

(c) Agent shall deliver the documents and papers received by it for the account of each Revolving Credit Lender to such Revolving Credit Lender. Unless Agent shall have been notified by any Revolving Credit Lender prior to the date of any proposed Revolving Credit Advance that such Revolving Credit Lender does not intend to make available to Agent such Revolving Credit Lender’s Percentage of such Advance, Agent may assume that such Revolving Credit Lender has made such amount available to Agent on such date, as aforesaid. Agent may, but shall not be obligated to, make available to Borrowers the amount of such payment in reliance on such assumption. If such amount is not in fact made available to Agent by such Revolving Credit Lender, as aforesaid, Agent shall be entitled to recover such amount on demand from such Revolving Credit Lender. If such Revolving Credit Lender does not pay such amount forthwith upon Agent’s demand therefor and the Agent has in fact made a corresponding amount available to Borrowers, the Agent shall promptly notify Borrowers and Borrowers shall pay such amount to Agent, if such notice is delivered to Borrowers prior to 1:00 p.m. (Detroit time) on a Business Day, on the day such notice is received, and otherwise on the next Business Day, and such amount paid by Borrowers shall be applied as a prepayment of the Revolving Credit (without any corresponding reduction in the Revolving Credit Aggregate Commitment), reimbursing Agent for having funded said amounts on behalf of such Revolving Credit Lender. The Borrowers shall retain their claims against such Revolving Credit Lender with respect to the amounts repaid by it to Agent and, if such Revolving Credit Lender subsequently makes such amounts available to Agent, Agent shall promptly make such amounts available to the Borrowers as a Revolving Credit Advance. Agent shall also be entitled to recover from such Revolving Credit Lender or Borrowers, as the case may be, but without duplication, interest on such amount in respect of each day from the date such amount was made available by Agent to Borrowers, to the date such amount is recovered by Agent, at a rate per annum equal to:

(i)

in the case of such Revolving Credit Lender, for the first two (2) Business Days such amount remains unpaid, the Federal Funds Effective Rate, and thereafter, at the rate of interest then applicable to such Revolving Credit Advances; and

(ii)

in the case of Borrowers, the rate of interest then applicable to such Advance of the Revolving Credit.

Until such Revolving Credit Lender has paid Agent such amount, such Revolving Credit Lender shall have no interest in or rights with respect to such Advance for any purpose whatsoever. The obligation of any Revolving Credit Lender to make any Revolving Credit Advance hereunder shall not be affected by the failure of any other Revolving Credit Lender to make any Advance hereunder, and no Revolving Credit Lender shall have any liability to the Borrowers or any of their respective Subsidiaries, the Agent, any other Revolving Credit Lender, or any other party for another Revolving Credit Lender’s failure to make any loan or Advance hereunder.

The Swing Line Lender may, on the terms and subject to the conditions hereinafter set forth (including without limitation Section 2.5(c) hereof), but shall not be required to, make one or more Advances (each such advance being a “Swing Line Advance”) to the Borrowers from time to time on any Business Day during the period from the Effective Date hereof until (but excluding) the Revolving Credit Maturity Date in an aggregate amount not to exceed at any one time outstanding the Swing Line Maximum Amount.

The entries made in such account or accounts of Swing Line Lender shall be prima facie evidence, absent manifest error, of the existence and amounts of the obligations of the Borrowers therein recorded; provided, however, that the failure of Swing Line Lender to maintain such account, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay the Swing Line Advances (and all other amounts owing with respect thereto) in accordance with the terms of this Agreement.

(ii)

Each Borrower agrees that, upon the written request of Swing Line Lender, the Borrowers will execute and deliver to Swing Line Lender a Swing Line Note.

(iii)

Each Borrower unconditionally promises to pay, jointly and severally, to the Swing Line Lender the then unpaid principal amount of such Swing Line Advance (plus all accrued and unpaid interest) on the Revolving Credit Maturity Date and on such other dates and in such other amounts as may be required from time to time pursuant to this Agreement.

(iv)

(A) in the case of a Swing Line Advance that is a Prime-based Advance, the principal amount of the initial funding of such Advance, as opposed to any refunding or conversion thereof, shall be at least Two Hundred Fifty Thousand Dollars ($250,000) or such lesser amount as may be agreed to by the Swing Line Lender, and (B) in the case of a Swing Line Advance that is a Quoted Rate Advance, the principal amount of such Advance, plus any other outstanding Swing Line Advances to be then combined therewith having the same Interest Period, if any, shall be at least Two Hundred Fifty Thousand Dollars ($250,000) or such lesser amount as may be agreed to by the Swing Line Lender, and at any time there shall not be in effect more than three (3) Interest Rates and Interest Periods;

(vii)

At the option of the Agent, subject to revocation by Agent at any time and from time to time and so long as the Agent is the Swing Line Lender, Borrowers may utilize the Agent’s “Sweep to Loan” automated system for obtaining Swing Line Advances and making periodic repayments. At any time during which the “Sweep to Loan” system is in effect, Swing Line Advances shall be advanced to fund borrowing needs pursuant to the terms of the Sweep Agreement. Each time a Swing Line Advance is made using the “Sweep to Loan” system, Borrowers shall be deemed to have certified to the Agent and the Lenders each of the matters set forth in clause (vi) of this Section 2.5(b). Principal and interest on Swing Line Advances requested, or deemed requested, pursuant to this Section shall be paid pursuant to the terms and conditions of the Sweep Agreement without any deduction, setoff or counterclaim whatsoever. Unless sooner paid pursuant to the provisions hereof or the provisions of the Sweep Agreement, the principal amount of the Swing Loans shall be paid in full, together with accrued interest thereon, on the Revolving Credit Maturity Date.

Swing Line Lender shall promptly notify Agent of any Swing Line Advance by telephone, telex or telecopier.

(e)

Refunding of or Participation Interest in Swing Line Advances.

(i)

The Agent, at any time in its sole and absolute discretion, may, in each case on behalf of the Borrowers (which hereby irrevocably directs the Agent to act on their behalf) request each of the Revolving Credit Lenders (including the Swing Line Lender in its capacity as a Revolving Credit Lender) to make an Advance of the Revolving Credit to Borrowers, in an amount equal to such Revolving Credit Lender’s Revolving Credit Percentage of the aggregate principal amount of the Swing Line Advances outstanding on the date such notice is given (the “Refunded Swing Line Advances”); provided however that the Swing Line Advances carried at the Quoted Rate which are refunded with Revolving Credit Advances at the request of the Swing Line Lender at a time when no Default or Event of Default has occurred and is continuing shall not be subject to Section 11.1 and no losses, costs or expenses may be assessed by the Swing Line Lender against the Borrowers or the Revolving Credit Lenders as a consequence of such refunding. The applicable Revolving Credit Advances used to refund any Swing Line Advances shall be Prime-based Advances. In connection with the making of any such Refunded Swing Line Advances or the purchase of a participation interest in Swing Line Advances under Section 2.5(e)(ii) hereof, the Swing Line Lender shall retain its claim against Borrowers for any unpaid interest or fees in respect thereof accrued to the date of such refunding. Unless any of the events described in Section 9.1(i) hereof shall have occurred (in which event the procedures of Section 2.5(e)(ii) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of a Revolving Credit Advance are then satisfied (but subject to Section 2.5(e)(iii)), each Revolving Credit Lender shall make the proceeds of its Revolving Credit Advance available to the Agent for the benefit of the Swing Line Lender at the office of the Agent specified in Section 2.4(a) hereof prior to 11:00 a.m. Detroit time on the Business Day next succeeding the date such notice is given, in immediately available funds. The proceeds of such Revolving Credit Advances shall be immediately applied to repay the Refunded Swing Line Advances, subject to Section 11.1 hereof.

(ii)

If, prior to the making of an Advance of the Revolving Credit pursuant to Section 2.5(e)(i) hereof, one of the events described in Section 9.1(i) hereof shall have occurred, each Revolving Credit Lender will, on the date such Advance of the Revolving Credit was to have been made, purchase from the Swing Line Lender an undivided participating interest in each Swing Line Advance that was to have been refunded in an amount equal to its Revolving Credit Percentage of such Swing Line Advance. Each Revolving Credit Lender within the time periods specified in Section 2.5(e)(i) hereof, as applicable, shall immediately transfer to the Agent, for the benefit of the Swing Line Lender, in immediately available funds, an amount equal to its Revolving Credit Percentage of the aggregate principal amount of all Swing Line Advances outstanding as of such date. Upon receipt thereof, the Agent will deliver to such Revolving Credit Lender a Swing Line Participation Certificate evidencing such participation.

(iii)

Each Revolving Credit Lender’s obligation to make Revolving Credit Advances to refund Swing Line Advances, and to purchase participation interests, in accordance with Section 2.5(e)(i) and (ii), respectively, shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (A) any set-off, counterclaim, recoupment, defense or other right which such Revolving Credit Lender may have against Swing Line Lender, Borrowers or any other Person for any reason whatsoever; (B) the occurrence or continuance of any Default or Event of Default; (C) any adverse change in the condition (financial or otherwise) of Borrowers or any other Person; (D) any breach of this Agreement or any other Loan Document by Borrowers or any other Person; (E) any inability of Borrowers to satisfy the conditions precedent to borrowing set forth in this Agreement on the date upon which such Revolving Credit Advance is to be made or such participating interest is to be purchased; (F) the termination of the Revolving Credit Aggregate Commitment hereunder; or (G) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If any Revolving Credit Lender does not make available to the Agent the amount required pursuant to Section 2.5(e)(i) or (ii) hereof, as the case may be, the Agent on behalf of the Swing Line Lender, shall be entitled to recover such amount on demand from such Revolving Credit Lender, together with interest thereon for each day from the date of non-payment until such amount is paid in full (x) for the first two (2) Business Days such amount remains unpaid, at the Federal Funds Effective Rate and (y) thereafter, at the rate of interest then applicable to such Swing Line Advances. The obligation of any Revolving Credit Lender to make available its pro rata portion of the amounts required pursuant to Section 2.5(e)(i) or (ii) hereof shall not be affected by the failure of any other Revolving Credit Lender to make such amounts available, and no Revolving Credit Lender shall have any liability to any Credit Party, the Agent, the Swing Line Lender, or any other Revolving Credit Lender or any other party for another Revolving Credit Lender’s failure to make available the amounts required under Section 2.5(e)(i) or (ii) hereof.

(iv)

Notwithstanding the foregoing, no Revolving Credit Lender shall be required to make any Revolving Credit Advance to refund a Swing Line Advance or to purchase a participation in a Swing Line Advance if at least two (2) Business Days prior to the making of such Swing Line Advance by the Swing Line Lender, the officers of the Swing Line Lender immediately responsible for matters concerning this Agreement shall have received written notice from Agent or any Lender that Swing Line Advances should be suspended based on the occurrence and continuance of a Default or Event of Default and stating that such notice is a “notice of default”; provided, however that the obligation of the Revolving Credit Lenders to make such Revolving Credit Advances (or purchase such participations) shall be reinstated upon the date on which such Default or Event of Default has been waived by the requisite Lenders.

2.6 Interest Payments; Default Interest

(a) Interest on the unpaid balance of all Prime-based Advances of the Revolving Credit and the Swing Line from time to time outstanding shall accrue from the date of such Advance to the date repaid, at a per annum interest rate equal to the Prime-based Rate, and shall be payable in immediately available funds commencing on December 1, and on the first day of each calendar month thereafter. Whenever any payment under this Section 2.6(a) shall become due on a day which is not a Business Day, the date for payment thereof shall be extended to the next Business Day. Interest accruing at the Prime-based Rate shall be computed on the basis of a 360 day year and assessed for the actual number of days elapsed, and in such computation effect shall be given to any change in the interest rate resulting from a change in the Prime-based Rate on the date of such change in the Prime-based Rate.

(b) Interest on each Eurodollar-based Advance of the Revolving Credit shall accrue at its Eurodollar-based Rate and shall be payable in immediately available funds on the last day of the Eurodollar-Interest Period applicable thereto (and, if any Eurodollar-Interest Period shall exceed three months, then on the last Business Day of the third month of such Eurodollar-Interest Period, and at three month intervals thereafter). Interest accruing at the Eurodollar-based Rate shall be computed on the basis of a 360 day year and assessed for the actual number of days elapsed from the first day of the Eurodollar-Interest Period applicable thereto to but not including the last day thereof.

(c) Interest on each Quoted Rate Advance of the Swing Line shall accrue at its Quoted Rate and shall be payable in immediately available funds on the last day of the Interest Period applicable thereto. Interest accruing at the Quoted Rate shall be computed on the basis of a 360-day year and assessed for the actual number of days elapsed from the first day of the Interest Period applicable thereto to, but not including, the last day thereof.

(d) Notwithstanding anything to the contrary in the preceding sections, all accrued and unpaid interest on any Revolving Credit Advance refunded or converted pursuant to Section 2.3 hereof and any Swing Line Advance refunded pursuant to Section 2.5(e) hereof, shall be due and payable in full on the date such Advance is refunded or converted.

(e) In the case of any Event of Default under Section 9.1(i), immediately upon the occurrence thereof, and in the case of any other Event of Default, immediately upon receipt by Agent of notice from the Majority Revolving Credit Lenders, interest shall be payable on demand on all Revolving Credit Advances and Swing Line Advances from time to time outstanding at a per annum rate equal to the Applicable Interest Rate in respect of each such Advance plus, in the case of Eurodollar-based Advances and Quoted Rate Advances, two percent (2%) for the remainder of the then existing Interest Period, if any, and at all other such times, and for all Prime-based Advances from time to time outstanding, at a per annum rate equal to the Prime-based Rate plus two percent (2%).

2.7 Optional Prepayments.

(a) (i) The Borrowers may prepay all or part of the outstanding principal of any Prime-based Advance(s) of the Revolving Credit at any time, provided that, unless the “Sweep to Loan” system shall be in effect in respect of the Revolving Credit, after giving effect to any partial prepayment, the aggregate balance of Prime-based Advance(s) of the Revolving Credit remaining outstanding shall be at least One Million Dollars ($1,000,000), and (ii) subject to Section 2.10(c) hereof, the Borrowers may prepay all or part of the outstanding principal of any Eurodollar-based Advance of the Revolving Credit at any time (subject to not less than five (5) Business Day’s notice to Agent) provided that, after giving effect to any partial prepayment, the unpaid portion of such Advance which is to be refunded or converted under Section 2.3 hereof shall be at least Two Million Five Hundred Thousand Dollars ($2,500,000).

(b) (i) The Borrowers may prepay all or part of the outstanding principal of any Swing Line Advance carried at the Prime-based Rate at any time, provided that after giving effect to any partial prepayment, the aggregate balance of such Prime-based Swing Line Advances remaining outstanding shall be at least One Hundred Thousand Dollars ($100,000) and (ii) subject to Section 2.10(c) hereof, the Borrowers may prepay all or part of the outstanding principal of any Swing Line Advance carried at the Quoted Rate at any time (subject to not less than one (1) day’s notice to the Swing Line Lender) provided that after giving effect to any partial prepayment, the aggregate balance of such Quoted Rate Swing Line Advances remaining outstanding shall be at least Two Hundred Fifty Thousand Dollars ($250,000).

(c) Any prepayment of a Prime-based Advance made in accordance with this Section shall be without premium or penalty and any prepayment of any other type of Advance shall be subject to the provisions of Section 11.1 hereof, but otherwise without premium or penalty.

2.8 Prime-based Advance in Absence of Election or Upon Default. If, (a) as to any outstanding Eurodollar-based Advance of the Revolving Credit or any outstanding Quoted Rate Advance of the Swing Line, Agent has not received payment of all outstanding principal and accrued interest on the last day of the Interest Period applicable thereto, or does not receive a timely Request for Advance meeting the requirements of Section 2.3 or 2.5 hereof with respect to the refunding or conversion of such Advance, or (b) if on the last day of the applicable Interest Period a Default or an Event of Default shall have occurred and be continuing, then, on the last day of the applicable Interest Period the principal amount of any Eurodollar-based Advance or Quoted Rate Advance, as the case may be, which has not been prepaid shall, absent a contrary election of the Majority Revolving Credit Lenders, be converted automatically to a Prime-based Advance and the Agent shall thereafter promptly notify Borrowers of said action. All accrued and unpaid interest on any Advance converted to a Prime-based Advance under this Section 2.8 shall be due and payable in full on the date such Advance is converted.

2.9 Revolving Credit Facility Fee. From the Effective Date to the Revolving Credit Maturity Date, the Borrowers shall pay, jointly and severally, to the Agent for distribution to the Lenders pro-rata in accordance with their respective Percentages, a Revolving Credit Facility Fee quarterly in arrears commencing January 1, 2008 and on the first day of each calendar quarter thereafter (in respect of the prior three months or any portion thereof). The Revolving Credit Facility Fee payable to each Lender shall be determined by multiplying the Applicable Fee Percentage times such Lender’s Revolving Credit Percentage of the Revolving Credit Aggregate Commitment then in effect (whether used or unused). The Revolving Credit Facility Fee shall be computed on the basis of a year of three hundred sixty (360) days and assessed for the actual number of days elapsed. Whenever any payment of the Revolving Credit Facility Fee shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next Business Day. Upon receipt of such payment, Agent shall make prompt payment to each Lender of its share of the Revolving Credit Facility Fee based upon its respective Percentage. It is expressly understood that the Revolving Credit Facility Fees described in this Section are not refundable.

2.10 Mandatory Repayment of Revolving Credit Advances.

(a) If at any time and for any reason the aggregate outstanding principal amount of Revolving Credit Advances plus Swing Line Advances, plus the outstanding Letter of Credit Obligations, shall exceed the Revolving Credit Aggregate Commitment, Borrowers shall immediately reduce any pending request for a Revolving Credit Advance on such day by the amount of such excess and, to the extent any excess remains thereafter, repay any Revolving Credit Advances and Swing Line Advances in an amount equal to the lesser of the outstanding amount of such Advances and the amount of such remaining excess, with such amounts to be applied between the Revolving Credit Advances and Swing Line Advances as determined by the Agent and then, to the extent that any excess remains after payment in full of all Revolving Credit Advances and Swing Line Advances, to provide cash collateral in support of any Letter of Credit Obligations in an amount equal to the lesser of (x) 105% of the amount of such Letter of Credit Obligations and (y) the amount of such remaining excess, with such cash collateral to be provided on the basis set forth in Section 9.2 hereof. Each Borrower acknowledges that, in connection with any repayment required hereunder, it shall also be responsible for the reimbursement of any prepayment or other costs required under Section 11.1 hereof. Any payments made pursuant to this Section shall be applied first to outstanding Prime-based Advances under the Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate and then to Eurodollar-based Advances of the Revolving Credit, and then to Swing Line Advances carried at the Quoted Rate.

(b) Intentionally omitted.

(c) To the extent that, on the date any mandatory repayment of the Revolving Credit Advances under this Section 2.10 or payment pursuant to the terms of any of the Loan Documents is due, the Indebtedness under the Revolving Credit or any other Indebtedness to be prepaid is being carried, in whole or in part, at the Eurodollar-based Rate and no Default or Event of Default has occurred and is continuing, Borrowers may deposit the amount of such mandatory prepayment in a cash collateral account to be held by the Agent, for and on behalf of the Revolving Credit Lenders, on such terms and conditions as are reasonably acceptable to Agent and upon such deposit the obligation of Borrowers to make such mandatory prepayment shall be deemed satisfied. Subject to the terms and conditions of said cash collateral account, sums on deposit in said cash collateral account shall be applied (until exhausted) to reduce the principal balance of the Revolving Credit on the last day of each Eurodollar-Interest Period attributable to the Eurodollar-based Advances of such Revolving Advance, thereby avoiding breakage costs under Section 11.1 hereof; provided, however, that if a Default or Event of Default shall have occurred at any time while sums are on deposit in the cash collateral account, Agent may, in its sole discretion, elect to apply such sums to reduce the principal balance of such Eurodollar-based Advances prior to the last day of the applicable Eurodollar-Interest Period, and the Borrowers will be obligated to pay any resulting breakage costs under Section 11.1.

2.11 Optional Reduction or Termination of Revolving Credit Aggregate Commitment. Borrowers may, upon at least five (5) Business Days’ prior written notice to the Agent, permanently reduce the Revolving Credit Aggregate Commitment in whole at any time, or in part from time to time, without premium or penalty, provided that: (i) each partial reduction of the Revolving Credit Aggregate Commitment shall be in an aggregate amount equal to One Million Dollars ($1,000,000) or a larger integral multiple of One Hundred Thousand Dollars ($100,000); (ii) each reduction shall be accompanied by the payment of the Revolving Credit Facility Fee, if any, accrued and unpaid to the date of such reduction; (iii) Borrowers shall prepay in accordance with the terms hereof the amount, if any, by which the aggregate unpaid principal amount of Revolving Credit Advances and Swing Line Advances (including, without duplication, any deemed Advances made under Section 3.6 hereof) outstanding hereunder, plus the Letter of Credit Obligations, exceeds the amount of the then applicable Revolving Credit Aggregate Commitment as so reduced, together with interest thereon to the date of prepayment; (iv) no reduction shall reduce the Revolving Credit Aggregate Commitment to an amount which is less than the aggregate undrawn amount of any Letters of Credit outstanding at such time; and (v) no such reduction shall reduce the Swing Line Maximum Amount unless Borrowers so elect, provided that the Swing Line Maximum Amount shall at no time be greater than the Revolving Credit Aggregate Commitment; provided, however that if the termination or reduction of the Revolving Credit Aggregate Commitment requires the prepayment of a Eurodollar-based Advance or a Quoted Rate Advance and such termination or reduction is made on a day other than the last Business Day of the then current Interest Period applicable to such Eurodollar-based Advance or such Quoted Rate Advance, then, pursuant to Section 11.1, Borrowers shall compensate the Revolving Credit Lenders and/or the Swing Line Lender for any losses or, so long as no Default or Event of Default has occurred and is continuing, Borrowers may deposit the amount of such prepayment in a collateral account as provided in Section 2.10(c). Reductions of the Revolving Credit Aggregate Commitment and any accompanying prepayments of Advances of the Revolving Credit shall be distributed by Agent to each Revolving Credit Lender in accordance with such Revolving Credit Lender’s Revolving Percentage thereof, and will not be available for reinstatement by or readvance to Borrowers and any accompanying prepayments of Advances of the Swing Line shall be distributed by Agent to the Swing Line Lender and will not be available for reinstatement by or readvance to the Borrowers. Any reductions of the Revolving Credit Aggregate Commitment hereunder shall reduce each Revolving Credit Lender’s portion thereof proportionately (based on the applicable Percentages), and shall be permanent and irrevocable. Any payments made pursuant to this Section shall be applied first to outstanding Prime-based Advances under the Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate and then to Eurodollar-based Advances of the Revolving Credit, and then to Swing Line Advances carried at the Quoted Rate.

2.12 Use of Proceeds of Advances. Advances of the Revolving Credit shall be used to finance working capital, to refinance existing Debt and to consummate the Acquisition and other lawful corporate purposes.

(g)

Issuing Lender shall have received the issuance fees required in connection with the issuance of such Letter of Credit pursuant to Section 3.4 hereof.

3.3 Notice. The Issuing Lender shall deliver to the Agent, concurrently with or promptly following its issuance of any Letter of Credit, a true and complete copy of each Letter of Credit. Promptly upon its receipt thereof, Agent shall give notice, substantially in the form attached as Exhibit E, to each Revolving Credit Lender of the issuance of each Letter of Credit, specifying the amount thereof and the amount of such Revolving Credit Lender’s Percentage thereof.

3.4 Letter of Credit Fees; Increased Costs. (a) Borrowers shall pay letter of credit fees as follows:

A per annum letter of credit fee with respect to the undrawn amount of each Letter of Credit issued pursuant hereto (based on the amount of each Letter of Credit) in the amount of the Applicable Fee Percentage (determined with reference to Schedule 1.1 to this Agreement) shall be paid to the Agent for distribution to the Revolving Credit Lenders in accordance with their Percentages.

(ii)

A letter of credit facing fee on the face amount of each Letter of Credit shall be paid to the Agent for distribution to the Issuing Lender for its own account, in accordance with the terms of the applicable Fee Letter.

(b)

All payments by Borrowers to the Agent for distribution to the Issuing Lender or the Revolving Credit Lenders under this Section 3.4 shall be made in Dollars in immediately available funds at the Issuing Office or such other office of the Agent as may be designated from time to time by written notice to Borrowers by the Agent. The fees described in clauses (a)(i) and (ii) above (i) shall be nonrefundable under all circumstances, (ii) in the case of fees due under clause (a)(i) above, shall be payable semi-annually in advance and (iii) in the case of fees due under clause (a)(ii) above, shall be payable upon the issuance of such Letter of Credit and upon any amendment thereto or extension thereof. The fees due under clause (a)(i) above shall be determined by multiplying the Applicable Fee Percentage times the undrawn amount of the face amount of each such Letter of Credit on the date of determination, and shall be calculated on the basis of a 360 day year and assessed for the actual number of days from the date of the issuance thereof to the stated expiration thereof. The parties hereto acknowledge that, unless the Issuing Lender otherwise agrees, any material amendment and any extension to a Letter of Credit issued hereunder shall be treated as a new Letter of Credit for the purposes of the letter of credit facing fee.

(c)

If any change in any law or regulation or in the interpretation thereof by any court or administrative or governmental authority charged with the administration thereof, adopted after the date hereof, shall either (i) impose, modify or cause to be deemed applicable any reserve, special deposit, limitation or similar requirement against letters of credit issued or participated in by, or assets held by, or deposits in or for the account of, Issuing Lender or any Revolving Credit Lender or (ii) impose on Issuing Lender or any Revolving Credit Lender any other condition regarding this Agreement, the Letters of Credit or any participations in such Letters of Credit, and the result of any event referred to in clause (i) or (ii) above shall be to increase the cost or expense to Issuing Lender or such Revolving Credit Lender of issuing or maintaining or participating in any of the Letters of Credit (which increase in cost or expense shall be determined by the Issuing Lender’s or such Revolving Credit Lender’s reasonable allocation of the aggregate of such cost increases and expenses resulting from such events), then, upon demand by the Issuing Lender or such Revolving Credit Lender, as the case may be, Borrowers shall, within thirty (30) days following demand for payment, pay to Issuing Lender or such Revolving Credit Lender, as the case may be, from time to time as specified by the Issuing Lender or such Revolving Credit Lender, additional amounts which shall be sufficient to compensate the Issuing Lender or such Revolving Credit Lender for such increased cost and expense (together with interest on each such amount from ten days after the date such payment is due until payment in full thereof at the Prime-based Rate), provided that if the Issuing Lender or such Revolving Credit Lender could take any reasonable action, without cost or administrative or other burden or restriction to such Lender, to mitigate or eliminate such cost or expense, it agrees to do so within a reasonable time after becoming aware of the foregoing matters. Each demand for payment under this Section 3.4(c) shall be accompanied by a certificate of Issuing Lender or the applicable Revolving Credit Lender setting forth the amount of such increased cost or expense incurred by the Issuing Lender or such Revolving Credit Lender, as the case may be, as a result of any event mentioned in clause (i) or (ii) above, and in reasonable detail, the methodology for calculating and the calculation of such amount, which certificate shall be prepared in good faith and shall be conclusive evidence, absent manifest error, as to the amount thereof.

3.5 Other Fees. In connection with the Letters of Credit, and in addition to the Letter of Credit Fees, Borrowers shall pay, for the sole account of the Issuing Lender, standard documentation, administration, payment and cancellation charges assessed by Issuing Lender or the Issuing Office, at the times, in the amounts and on the terms set forth or to be set forth from time to time in the standard fee schedule of the Issuing Office in effect from time to time.

3.6 Drawings and Demands for Payment Under Letters of Credit.

(a) If the Issuing Lender shall honor a draft or other demand for payment presented or made under any Letter of Credit, each Borrower agrees to pay to the Issuing Lender an amount equal to the amount paid by the Issuing Lender in respect of such draft or other demand under such Letter of Credit and all reasonable expenses paid or incurred by the Agent relative thereto not later than 1:00 p.m. (Detroit time), on (i) the Business Day that Borrowers receive notice of such presentment and honor, if such notice is received prior to 11:00 a.m. (Detroit time) or (ii) the Business Day immediately following the day that Borrowers received such notice, if such notice is received after 11:00 a.m. (Detroit time). Unless Borrowers shall have made such payment to the Agent for the account of the Issuing Lender on such day, the Agent shall be deemed to have disbursed to Borrowers and to have elected to substitute for the reimbursement obligation, with respect to the applicable Letter of Credit honored by the Issuing Lender, a Prime-based Advance of the Revolving Credit (which Advance may be subsequently converted at any time into a Eurodollar-based Advance pursuant to Section 2.3 hereof) on behalf of and for the account of the Revolving Credit Lenders in an aggregate amount equal to the amount so paid by the Issuing Lender in respect of such draft or other demand under such Letter of Credit. Such Prime-based Advance shall be deemed disbursed notwithstanding any failure to satisfy any conditions for disbursement of any Advance set forth in Section 2 hereof and, to the extent of the Advances so disbursed, the reimbursement obligation of Borrowers under this Section 3.6 shall be deemed satisfied.

(b) If the Issuing Lender shall honor a draft or other demand for payment presented or made under any Letter of Credit, the Issuing Lender shall provide notice thereof to Borrowers on the date such draft or demand is honored, and to each Revolving Credit Lender on such date unless Borrowers shall have satisfied their reimbursement obligations under Section 3.6(a) hereof by payment to the Agent (for the benefit of the Issuing Lender) on such date. The Issuing Lender shall further use reasonable efforts to provide notice to Borrowers prior to honoring any such draft or other demand for payment, but such notice, or the failure to provide such notice, shall not affect the rights or obligations of the Issuing Lender with respect to any Letter of Credit or the rights and obligations of the parties hereto, including without limitation the obligations of Borrowers under Section 3.6(a) hereof.

(c) Upon issuance by the Issuing Lender of each Letter of Credit hereunder, each Revolving Credit Lender shall automatically acquire a pro rata participation interest in such Letter of Credit and each related Letter of Credit Payment based on its respective Revolving Credit Percentage. Each Revolving Credit Lender, on the date a draft or demand under any Letter of Credit is honored (or the next succeeding Business Day if the notice required to be given by Issuing Lender to the Revolving Credit Lenders under Section 3.6(b) hereof is not given to the Revolving Credit Lenders prior to 2:00 p.m. (Detroit time) on such date of draft or demand), shall make its Revolving Credit Percentage of the amount paid by the Issuing Lender, and not reimbursed by Borrowers on such day, in immediately available funds at the principal office of the Agent for the account of Issuing Lender. If and to the extent such Revolving Credit Lender shall not have made such pro rata portion available to the Agent, such Revolving Credit Lender agrees to pay to the Agent for the account of the Issuing Lender forthwith on demand such amount together with interest thereon, for each day from the date such amount was paid by the Issuing Lender until such amount is so made available to the Agent at the Federal Funds Rate for the first three days and thereafter at a Prime-based Rate applicable during such period to the related Advance deemed to have been disbursed under Section 3.6(a) in respect of the reimbursement obligation of Borrowers. If such Revolving Credit Lender shall pay such amount to the Agent for the account of Issuing Lender together with such interest, if any, such amount so paid shall be deemed to constitute an Advance by such Revolving Credit Lender disbursed in respect of the reimbursement obligation of Borrowers under Section 3.6(a) hereof for purposes of this Agreement, effective as of the dates applicable under said Section 3.6(a). The failure of any Revolving Credit Lender to make its pro rata portion of any such amount paid by the Issuing Lender available to the Agent for the account of Issuing Lender shall not relieve any other Revolving Credit Lender of its obligation to make available its pro rata portion of such amount, but no Revolving Credit Lender shall be responsible for failure of any other Revolving Credit Lender to make such pro rata portion available to the Agent for the account of Issuing Lender.

Notwithstanding the foregoing however no Revolving Credit Lender shall be deemed to have acquired a participation in a Letter of Credit if the officers of the Issuing Lender immediately responsible for matters concerning this Agreement shall have received written notice from Agent or any Lender at least two (2) Business Days prior to the date of the issuance of such Letter of Credit that the issuance of Letters of Credit should be suspended based on the occurrence and continuance of a Default or Event of Default and stating that such notice is a “notice of default”; provided, however that the Revolving Credit Lenders shall be deemed to have acquired such a participation upon the date on which such Default or Event of Default has been waived by the requisite Revolving Credit Lenders, as applicable. In the event that the Issuing Lender receives such a notice, the Issuing Lender shall have no obligation to issue any Letter of Credit until such notice is withdrawn by Agent or such Lender or until the requisite Lenders have waived such Default or Event of Default in accordance with the terms of this Agreement.

(d) Nothing in this Agreement shall be construed to require or authorize any Revolving Credit Lender to issue any Letter of Credit, it being recognized that the Issuing Lender shall be the sole issuer of Letters of Credit under this Agreement.

3.7 Obligations Irrevocable. The obligations of Borrowers to make payments to Agent for the account of Issuing Lender or the Revolving Credit Lenders with respect to Letter of Credit Obligations under Section 3.6 hereof, shall be unconditional and irrevocable and not subject to any qualification or exception whatsoever, including, without limitation:

(a)

Any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement, any other documentation relating to any Letter of Credit, this Agreement or any of the other Loan Documents (the “Letter of Credit Documents”);

(b)

Any amendment, modification, waiver, consent, or any substitution, exchange or release of or failure to perfect any interest in collateral or security, with respect to or under any Letter of Credit Document;

(c)

The existence of any claim, setoff, defense or other right which Borrowers may have at any time against any beneficiary or any transferee of any Letter of Credit (or any persons or entities for whom any such beneficiary or any such transferee may be acting), the Agent, the Issuing Lender or any Revolving Credit Lender or any other Person, whether in connection with this Agreement, any of the Letter of Credit Documents, the transactions contemplated herein or therein or any unrelated transactions;

(d)

Any draft or other statement or document presented under any 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;

(e)

Payment by the Issuing Lender to the beneficiary under any Letter of Credit against presentation of documents which do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit;

(f)

Any failure, omission, delay or lack on the part of the Agent, Issuing Lender or any Revolving Credit Lender or any party to any of the Letter of Credit Documents to enforce, assert or exercise any right, power or remedy conferred upon the Agent, Issuing Lender, any Revolving Credit Lender or any such party under this Agreement, any of the other Loan Documents or any of the Letter of Credit Documents, or any other acts or omissions on the part of the Agent, Issuing Lender, any Revolving Credit Lender or any such party; or

(g)

Any other event or circumstance that would, in the absence of this Section 3.7, result in the release or discharge by operation of law or otherwise of Borrowers from the performance or observance of any obligation, covenant or agreement contained in Section 3.6 hereof.

No setoff, counterclaim, reduction or diminution of any obligation or any defense of any kind or nature which any Borrower has or may have against the beneficiary of any Letter of Credit shall be available hereunder to such Borrower against the Agent, Issuing Lender or any Revolving Credit Lender. With respect to any Letter of Credit, nothing contained in this Section 3.7 shall be deemed to prevent any Borrower, after satisfaction in full of the absolute and unconditional obligations of Borrowers hereunder with respect to such Letter of Credit, from asserting in a separate action any claim, defense, set off or other right which they (or any of them) may have against Agent, Issuing Lender or any Revolving Credit Lender in connection with such Letter of Credit.

3.8 Risk Under Letters of Credit.

(a) In the administration and handling of Letters of Credit and any security therefor, or any documents or instruments given in connection therewith, Issuing Lender shall have the sole right to take or refrain from taking any and all actions under or upon the Letters of Credit.

(b) Subject to other terms and conditions of this Agreement, Issuing Lender shall issue the Letters of Credit and shall hold the documents related thereto in its own name and shall make all collections thereunder and otherwise administer the Letters of Credit in accordance with Issuing Lender’s regularly established practices and procedures and will have no further obligation with respect thereto. In the administration of Letters of Credit, Issuing Lender shall not be liable for any action taken or omitted on the advice of counsel, accountants, appraisers or other experts selected by Issuing Lender with due care and Issuing Lender may rely upon any notice, communication, certificate or other statement from Borrowers, beneficiaries of Letters of Credit, or any other Person which Issuing Lender believes to be authentic. Issuing Lender will, upon request, furnish the Revolving Credit Lenders with copies of Letter of Credit Documents related thereto.

(c) In connection with the issuance and administration of Letters of Credit and the assignments hereunder, Issuing Lender makes no representation and shall have no responsibility with respect to (i) the obligations of Borrowers or the validity, sufficiency or enforceability of any document or instrument given in connection therewith, or the taking of any action with respect to same, (ii) the financial condition of, any representations made by, or any act or omission of Borrowers or any other Person, or (iii) any failure or delay in exercising any rights or powers possessed by Issuing Lender in its capacity as issuer of Letters of Credit in the absence of its gross negligence or willful misconduct. Each of the Revolving Credit Lenders expressly acknowledges that it has made and will continue to make its own evaluations of Borrowers’ creditworthiness without reliance on any representation of Issuing Lender or Issuing Lender’s officers, agents and employees.

(d) If at any time Issuing Lender shall recover any part of any unreimbursed amount for any draw or other demand for payment under a Letter of Credit, or any interest thereon, Agent or Issuing Lender, as the case may be, shall receive same for the prorata benefit of the Revolving Credit Lenders in accordance with their respective Percentages and shall promptly deliver to each Revolving Credit Lender its share thereof, less such Revolving Credit Lender’s pro rata share of the costs of such recovery, including court costs and attorney’s fees. If at any time any Revolving Credit Lender shall receive from any source whatsoever any payment on any such unreimbursed amount or interest thereon in excess of such Revolving Credit Lender’s Percentage of such payment, such Revolving Credit Lender will promptly pay over such excess to Agent, for redistribution in accordance with this Agreement.

3.9 Indemnification. Each Borrower hereby indemnifies and agrees to hold harmless the Revolving Credit Lenders, the Issuing Lender and the Agent and their respective Affiliates, and the respective officers, directors, employees and agents of such Persons (each an “L/C Indemnified Person”), from and against any and all claims, damages, losses, liabilities, costs or expenses of any kind or nature whatsoever which the Revolving Credit Lenders, the Issuing Lender or the Agent or any such Person may incur or which may be claimed against any of them by reason of or in connection with any Letter of Credit (collectively, the “L/C Indemnified Amounts”), and none of the Issuing Lender, any Revolving Credit Lender or the Agent or any of their respective officers, directors, employees or agents shall be liable or responsible for:

(a)

the use which may be made of any Letter of Credit or for any acts or omissions of any beneficiary in connection therewith;

(b)

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

(c)

payment by the Issuing Lender to the beneficiary under any Letter of Credit against presentation of documents which do not strictly comply with the terms of any Letter of Credit (unless such payment resulted from the gross negligence or willful misconduct of the Issuing Lender), including failure of any documents to bear any reference or adequate reference to such Letter of Credit;

(d)

any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit; or

(e)

This Agreement is being executed and delivered by the Borrowers to Agent and the Lenders in good faith and in exchange for fair, equivalent consideration. The Credit Parties do not intend to nor does management of the Credit Parties believe the Credit Parties will incur debts beyond their ability to pay as they mature.

Enter into any arrangement with any Person providing for (a) the leasing by a Credit Party of real or personal property which has been or is to be sold or transferred by such Credit Party to such Person or to any other Person to whom funds have been or are to be advanced by such Person on the security of such property or rental obligations of such Credit Party, as the case may be, (b) sell any accounts or notes receivable or (c) enter into any synthetic lease (being an operating lease which has been structured so that it is not recorded as a liability on the balance sheet of any of the Credit Parties).

9.2 Exercise of Remedies. If an Event of Default has occurred and is continuing hereunder: (a) the Agent may, and shall, upon being directed to do so by the Majority Revolving Credit Lenders, declare the Revolving Credit Aggregate Commitment terminated; (b) the Agent may, and shall, upon being directed to do so by the Majority Lenders, upon notice to the Borrower Representative, declare the entire unpaid principal Indebtedness, including the Notes, immediately due and payable, without presentment, notice (other than as set forth in this Section) or demand, all of which are hereby expressly waived by the Borrowers; (c) upon the occurrence of any Event of Default specified in Section 9.1(i) and notwithstanding the lack of any declaration by Agent under preceding clauses (a) or (b), the entire unpaid principal Indebtedness shall become automatically and immediately due and payable, and the Revolving Credit Aggregate Commitment shall be automatically and immediately terminated; (d) the Agent shall, upon being directed to do so by the Majority Revolving Credit Lenders, demand immediate delivery of cash collateral, and each Borrower agrees to deliver such cash collateral upon demand, in an amount equal to 105% of the maximum amount that may be available to be drawn at any time prior to the stated expiry of all outstanding Letters of Credit, for deposit into an account controlled by the Agent; (e) the Agent may, and shall, upon being directed to do so by the Majority Lenders, notify Borrowers or any Credit Party that interest shall be payable on demand on all Indebtedness (other than Revolving Credit Advances and Swing Line Advances with respect to which Sections 2.6 hereof shall govern) owing from time to time to the Agent or any Lender, at a per annum rate equal to the then applicable Prime-based Rate plus two percent (2%); and (f) the Agent may, and shall, upon being directed to do so by the Majority Lenders or the Lenders, as applicable (subject to the terms hereof), exercise any remedy permitted by this Agreement, the other Loan Documents or law.

9.3 Rights Cumulative. No delay or failure of Agent and/or Lenders in exercising any right, power or privilege hereunder shall affect such right, power or privilege, nor shall any single or partial exercise thereof preclude any further exercise thereof, or the exercise of any other power, right or privilege. The rights of Agent and Lenders under this Agreement are cumulative and not exclusive of any right or remedies which Lenders would otherwise have.

9.4 Waiver by Borrowers of Certain Laws. To the extent permitted by applicable law, each Borrower hereby agrees to waive, and does hereby absolutely and irrevocably waive and relinquish the benefit and advantage of any valuation, stay, appraisement, extension or redemption laws now existing or which may hereafter exist, which, but for this provision, might be applicable to any sale made under the judgment, order or decree of any court, on any claim for interest on the Notes, or any security interest or mortgage contemplated by or granted under or in connection with this Agreement. These waivers have been voluntarily given, with full knowledge of the consequences thereof.

9.5 Waiver of Defaults. No Event of Default shall be waived by the Lenders except in a writing signed by an officer of the Agent in accordance with Section 13.10 hereof. No single or partial exercise of any right, power or privilege hereunder, nor any delay in the exercise thereof, shall preclude other or further exercise of their rights by Agent or the Lenders. No waiver of any Event of Default shall extend to any other or further Event of Default. No forbearance on the part of the Agent or the Lenders in enforcing any of their rights shall constitute a waiver of any of their rights. Each Borrower expressly agrees that this Section may not be waived or modified by the Lenders or Agent by course of performance, estoppel or otherwise.

9.6 Set Off. Upon the occurrence and during the continuance of any Event of Default, each Lender may at any time and from time to time, without notice to Borrowers but subject to the provisions of Section 10.3 hereof (any requirement for such notice being expressly waived by Borrowers), setoff and apply against any and all of the obligations of Borrowers now or hereafter existing under this Agreement, whether owing to such Lender, any Affiliate of such Lender or any other Lender or the Agent, any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of Borrowers and any property of Borrowers from time to time in possession of such Lender, irrespective of whether or not such deposits held or indebtedness owing by such Lender may be contingent and unmatured and regardless of whether any Collateral then held by Agent or any Lender is adequate to cover the Indebtedness. Promptly following any such setoff, such Lender shall give written notice to Agent and Borrowers of the occurrence thereof. Each Borrower hereby grants to the Lenders and the Agent a lien on and security interest in all such deposits, indebtedness and property as collateral security for the payment and performance of all of the obligations of Borrowers under this Agreement. The rights of each Lender under this Section 9.6 are in addition to the other rights and remedies (including, without limitation, other rights of setoff) which such Lender may have.

10.

PAYMENTS, RECOVERIES AND COLLECTIONS.

10.1 Payment Procedure.

(a) All payments to be made by Borrowers shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise provided herein, all payments made by the Borrowers of principal, interest or fees hereunder shall be made without setoff or counterclaim on the date specified for payment under this Agreement and must be received by Agent not later than 1:00 p.m. (Detroit time) on the date such payment is required or intended to be made in Dollars in immediately available funds to Agent at Agent’s office located at Xxx Xxxxxxx Xxxxxx, Xxxxxxx, Xxxxxxxx 00000-0000 for the ratable benefit of the Revolving Credit Lenders in the case of payments in respect of the Revolving Credit and any Letter of Credit Obligations. Any payment received by the Agent after 1:00 p.m. (Detroit time) shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. Upon receipt of each such payment, the Agent shall make prompt payment to each applicable Lender, or, in respect of Eurodollar-based Advances, such Lender’s Eurodollar Lending Office, in like funds and currencies, of all amounts received by it for the account of such Lender.

(b) Unless the Agent shall have been notified in writing by Borrowers at least two (2) Business Days prior to the date on which any payment to be made by Borrowers is due that no Borrower intends to remit such payment, the Agent may, in its sole discretion and without obligation to do so, assume that Borrowers have remitted such payment when so due and the Agent may, in reliance upon such assumption, make available to each Revolving Credit Lender, on such payment date an amount equal to such Lender’s share of such assumed payment. If Borrowers have not in fact remitted such payment to the Agent, each Lender shall forthwith on demand repay to the Agent the amount of such assumed payment made available or transferred to such Lender, together with the interest thereon, in respect of each day from and including the date such amount was made available by the Agent to such Lender to the date such amount is repaid to the Agent at a rate per annum equal to the Federal Funds Effective Rate for the first two (2) Business Days that such amount remains unpaid, and thereafter at a rate of interest then applicable to such Revolving Credit Advances.

(c) Subject to the definition of “Interest Period” in Section 1 of this Agreement, whenever any payment to be made hereunder shall otherwise be due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in computing interest, if any, in connection with such payment.

(d) All payments to be made by Borrowers under this Agreement or any of the Notes (including without limitation payments under the Swing Line and/or Swing Line Note) shall be made without setoff or counterclaim, as aforesaid, and, subject to full compliance by each Lender (and each assignee and participant pursuant to Section 13.8) with Section 13.13, without deduction for or on account of any present or future withholding or other taxes of any nature imposed by any governmental authority or of any political subdivision thereof or any federation or organization of which such governmental authority may at the time of payment be a member (other than any taxes on the overall income, net income, net profits or net receipts or similar taxes (or any franchise taxes imposed in lieu of such taxes) on the Agent or any Lender (or any branch maintained by Agent or a Lender) as a result of a present or former connection between the Agent or such Lender and the governmental authority, political subdivision, federation or organization imposing such taxes), unless Borrowers are compelled by law to make payment subject to such tax. In such event, Borrowers shall:

(i)

pay to the Agent for Agent’s own account and/or, as the case may be, for the account of the Lenders such additional amounts as may be necessary to ensure that the Agent and/or such Lender or Lenders (including the Swing Line Lender) receive a net amount equal to the full amount which would have been receivable had payment not been made subject to such tax; and

(ii)

remit such tax to the relevant taxing authorities according to applicable law, and send to the Agent or the applicable Lender or Lenders (including the Swing Line Lender), as the case may be, such certificates or certified copy receipts as the Agent or such Lender or Lenders shall reasonably require as proof of the payment by Borrowers of any such taxes payable by Borrowers.

As used herein, the terms “tax”, “taxes” and “taxation” include all taxes, levies, imposts, duties, fees, deductions and withholdings or similar charges together with interest (and any taxes payable upon the amounts paid or payable pursuant to this Section 10.1) thereon. Each Borrower shall be reimbursed by the applicable Lender for any payment made by such Borrower under this Section 10.1 if the applicable Lender is not in compliance with its obligations under Section 13.13 at the time of such Borrower’s payment.

10.2 Application of Proceeds of Collateral. Notwithstanding anything to the contrary in this Agreement, in the case of any Event of Default under Section 9.1(i), immediately following the occurrence thereof, and in the case of any other Event of Default, upon the termination of the Revolving Credit Aggregate Commitment, the acceleration of any Indebtedness arising under this Agreement and/or the exercise of any other remedy in each case by the requisite Lenders under Section 9.2 hereof, the Agent shall apply the proceeds of any Collateral, together with any offsets, voluntary payments by any Credit Party or others and any other sums received or collected in respect of the Indebtedness first, to pay all incurred and unpaid fees and expenses of the Agent under the Loan Documents and any protective advances made by Agent with respect to the Collateral under or pursuant to the terms of any Loan Document, next, to pay any fees and expenses owed to the Issuing Lender hereunder, next, to the Indebtedness under the Revolving Credit (including the Swing Line and any Reimbursement Obligations), any obligations owing by any Credit party under any Hedging Agreements or in connection with any Lender Products on a pro rata basis, next, to any other Indebtedness on a pro rata basis, and then, if there is any excess, to the Credit Parties or as otherwise required under applicable law, as the case may be.

10.3 Pro-rata Recovery. If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of principal of, or interest on, any of the Advances made by it, or the participations in Letter of Credit Obligations or Swing Line Advances held by it in excess of its pro rata share of payments then or thereafter obtained by all Lenders upon principal of and interest on all such Indebtedness, such Lender shall purchase from the other Lenders such participations in the Revolving Credit and/or the Letter of Credit Obligation held by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably in accordance with the applicable Percentages of the Lenders; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing holder, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

11.

CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS.

11.1 Reimbursement of Prepayment Costs. If (i) Borrowers make any payment of principal with respect to any Eurodollar-based Advance or Quoted Rate Advance on any day other than the last day of the Interest Period applicable thereto (whether voluntarily, pursuant to any mandatory provisions hereof, by acceleration, or otherwise); (ii) Borrowers convert or refund (or attempt to convert or refund) any such Advance on any day other than the last day of the Interest Period applicable thereto (except as described in Section 2.5(e)); (iii) Borrowers fail to borrow, refund or convert any Eurodollar-based Advance or Quoted Rate Advance after notice has been given by Borrowers to Agent in accordance with the terms hereof requesting such Advance; or (iv) or if the Borrowers fail to make any payment of principal in respect of a Eurodollar-based Advance or Quoted Rate Advance when due, the Borrowers shall jointly and severally reimburse Agent for itself and/or on behalf of any Lender, as the case may be, within ten (10) Business Days of written demand therefor for any resulting loss, cost or expense incurred (excluding the loss of any Applicable Margin) by Agent and Lenders, as the case may be, as a result thereof, including, without limitation, any such loss, cost or expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties, whether or not Agent and Lenders, as the case may be, shall have funded or committed to fund such Advance. The amount payable hereunder by Borrowers (jointly and severally) and to Agent for itself and/or on behalf of any Lender, as the case may be, shall be deemed to equal an amount equal to the excess, if any, of (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant Interest Period, at the applicable rate of interest for said Advance(s) provided under this Agreement, over (b) the amount of interest (as reasonably determined by Agent and Lenders, as the case may be) which would have accrued to Agent and Lenders, as the case may be, on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurocurrency market. Calculation of any amounts payable to any Lender under this paragraph shall be made as though such Lender shall have actually funded or committed to fund the relevant Advance through the purchase of an underlying deposit in an amount equal to the amount of such Advance and having a maturity comparable to the relevant Interest Period; provided, however, that any Lender may fund any Eurodollar-based Advance or Quoted Rate Advance, as the case may be, in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts payable under this paragraph. Upon the written request of Borrower Representative, Agent and Lenders shall deliver to Borrower Representative a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct, absent manifest error.

11.2 Eurodollar Lending Office. For any Eurodollar Advance, if Agent or a Lender, as applicable, shall designate a Eurodollar Lending Office which maintains books separate from those of the rest of Agent or such Lender, Agent or such Lender, as the case may be, shall have the option of maintaining and carrying the relevant Advance on the books of such Eurodollar Lending Office.

11.3 Circumstances Affecting Eurodollar-based Rate Availability. If, with respect to any Eurodollar-Interest Period, Agent or the Majority Lenders (after consultation with Agent) shall determine in good faith that, by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in eurodollars in the applicable amounts are not being offered to the Agent or such Lenders for such Eurodollar-Interest Period, then Agent shall forthwith give notice thereof to Borrower Representative. Thereafter, until Agent notifies the Borrower Representative that such circumstances no longer exist, (i) the obligation of Lenders to make Eurodollar-based Advances, and the right of Borrowers to convert an Advance to or refund an Advance as a Eurodollar-based Advance, as the case may be, shall be suspended, and (ii) effective upon the last day of each Eurodollar-Interest Period related to any existing Eurodollar-based Advance, each such Eurodollar-based Advance shall automatically be converted into a Prime-based Advance (without regard to satisfaction of any conditions to conversion contained elsewhere herein).

11.4 Laws Affecting Eurodollar-based Advance Availability. If, after the date of this Agreement, the adoption or introduction of, or any change in, any applicable law, rule or regulation or in the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Eurodollar Lending Offices) with any request or directive (whether or not having the force of law) of any such authority, shall make it unlawful or impossible for any of the Lenders (or any of their respective Eurodollar Lending Offices) to honor its obligations hereunder to make or maintain any Advance with interest at the Eurodollar-based Rate, such Lender shall forthwith give notice thereof to Borrower Representative and to Agent. Thereafter, (a) the obligations of the applicable Lenders to make Eurodollar-based Advances and the right of Borrowers to convert an Advance into or refund an Advance as a Eurodollar-based Advance shall be suspended and thereafter Borrowers may select as Applicable Interest Rates only those which remain available and which are permitted to be selected hereunder, and (b) if any of the Lenders may not lawfully continue to maintain an Advance to the end of the then current Eurodollar-Interest Period applicable thereto as a Eurodollar-based Advance, the applicable Advance shall immediately be converted to a Prime-based Advance and the Prime-based Rate shall be applicable thereto for the remainder of such Eurodollar-Interest Period. For purposes of this Section, a change in law, rule, regulation, interpretation or administration shall include, without limitation, any change made or which becomes effective on the basis of a law, rule, regulation, interpretation or administration presently in force, the effective date of which change is delayed by the terms of such law, rule, regulation, interpretation or administration.

11.5 Increased Cost of Eurodollar-based Advances. If, after the date of this Agreement, the adoption or introduction of, or any change in, any applicable law, rule or regulation or in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Eurodollar Lending Offices) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(a)

shall subject any of the Lenders (or any of their respective Eurodollar Lending Offices) to any tax, duty or other charge with respect to any Advance or shall change the basis of taxation of payments to any of the Lenders (or any of their respective Eurodollar Lending Offices) of the principal of or interest on any Advance or any other amounts due under this Agreement in respect thereof (except for changes in the rate of tax on the overall net income of any of the Lenders or any of their respective Eurodollar Lending Offices); or

(b)

shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any of the Lenders (or any of their respective Eurodollar Lending Offices) or shall impose on any of the Lenders (or any of their respective Eurodollar Lending Offices) or the foreign exchange and interbank markets any other condition affecting any Advance;

and the result of any of the foregoing matters is to increase the costs to any of the Lenders of maintaining any part of the Indebtedness hereunder as a Eurodollar-based Advance or to reduce the amount of any sum received or receivable by any of the Lenders under this Agreement in respect of a Eurodollar-based Advance, then such Lender shall promptly notify Agent, and Agent shall promptly notify Borrower Representative of such fact and demand compensation therefor and, within ten (10) Business Days after such notice, Borrowers jointly and severally agree to pay to such Lender or Lenders such additional amount or amounts as will compensate such Lender or Lenders for such increased cost or reduction, provided that each Lender agrees to take any reasonable action, to the extent such action could be taken without cost or administrative or other burden or restriction to such Lender, to mitigate or eliminate such cost or reduction, within a reasonable time after becoming aware of the foregoing matters. Agent will promptly notify Borrower Representative of any event of which it has knowledge which will entitle Lenders to compensation pursuant to this Section, or which will cause Borrowers to incur additional liability under Section 11.1 hereof, provided that Agent shall incur no liability whatsoever to the Lenders or Borrowers in the event it fails to do so. A certificate of Agent (or such Lender, if applicable) setting forth the basis for determining such additional amount or amounts necessary to compensate such Lender or Lenders shall accompany such demand and shall be conclusively presumed to be correct absent manifest error.

11.6 Capital Adequacy and Other Increased Costs.

(a)

If, after the date of this Agreement, the adoption or introduction of, or any change in any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to any Lender or Agent, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by any Lender or Agent with any guideline, request or directive of any such authority (whether or not having the force of law), including any risk based capital guidelines, affects or would affect the amount of capital required to be maintained by such Lender or Agent (or any corporation controlling such Lender or Agent) and such Lender or Agent, as the case may be, determines that the amount of such capital is increased by or based upon the existence of such Lender’s or Agent’s obligations or Advances hereunder and such increase has the effect of reducing the rate of return on such Lender’s or Agent’s (or such controlling corporation’s) capital as a consequence of such obligations or Advances hereunder to a level below that which such Lender or Agent (or such controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender or Agent to be material (collectively, “Increased Costs”), then Agent or such Lender shall notify the Borrower Representative, and thereafter Borrowers shall pay, jointly and severally, to such Lender or Agent, as the case may be, within ten (10) Business Days of written demand therefor from such Lender or Agent, additional amounts sufficient to compensate such Lender or Agent (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which such Lender or Agent reasonably determines to be allocable to the existence of such Lender’s or Agent’s obligations or Advances hereunder. A statement setting forth the amount of such compensation, the methodology for the calculation and the calculation thereof which shall also be prepared in good faith and in reasonable detail by such Lender or Agent, as the case may be, shall be submitted by such Lender or by Agent to Borrower Representative, reasonably promptly after becoming aware of any event described in this Section 11.6(a) and shall be conclusively presumed to be correct, absent manifest error.

(b)

Notwithstanding the foregoing, however, Borrowers shall not be required to pay any increased costs under Sections 11.5, 11.6 or 3.4(c) for any period ending prior to the date that is 180 days prior to the making of a Lender’s initial request for such additional amounts unless the applicable change in law or other event resulting in such increased costs is effective retroactively to a date more than 180 days prior to the date of such request, in which case a Lender’s request for such additional amounts relating to the period more than 180 days prior to the making of the request must be given not more than 180 days after such Lender becomes aware of the applicable change in law or other event resulting in such increased costs.

11.7 Right of Lenders to Fund through Branches and Affiliates. Each Lender (including without limitation the Swing Line Lender) may, if it so elects, fulfill its commitment as to any Advance hereunder by designating a branch or Affiliate of such Lender to make such Advance; provided that (a) such Lender shall remain solely responsible for the performances of its obligations hereunder and (b) no such designation shall result in any material increased costs to Borrowers.

11.8 Margin Adjustment. Adjustments to the Applicable Margins and the Applicable Fee Percentages, based on Schedule 1.1, shall be implemented on a quarterly basis as follows:

(a)

Such adjustments shall be given prospective effect only, effective as to all Advances outstanding hereunder, the Applicable Fee Percentage and the Letter of Credit Fee, upon the date of delivery of the financial statements under Sections 7.1(a) and 7.1(b) hereunder and the Covenant Compliance Report under Section 7.2(a) hereof, in each case establishing applicability of the appropriate adjustment and in each case with no retroactivity or claw-back. In the event Borrowers shall fail timely to deliver such financial statements or the Covenant Compliance Report and such failure continues for three (3) days, then (but without affecting the Event of Default resulting therefrom) from the date delivery of such financial statements and report was required until such financial statements and report are delivered, the Applicable Margins and Applicable Fee Percentages shall be at the highest level on the Pricing Matrix attached to this Agreement as Schedule 1.1.

(b)

From the Effective Date until the required date of delivery (or, if earlier, delivery) of the financial statements under Section 7.1(a) or 7.1(b) hereof, as applicable, and the Covenant Compliance Report under Section 7.2(a) hereof, for the fiscal quarter ending December 31, 2007, the Applicable Margins and Applicable Fee Percentages shall be those set forth under the Level II column of the pricing matrix attached to this Agreement as Schedule 1.1. Thereafter, Applicable Margins and Applicable Fee Percentages shall be based upon the quarterly financial statements and Covenant Compliance Reports, subject to recalculation as provided in Section 11.8(a) above.

(c)

Notwithstanding the foregoing, however, if, prior to the payment and discharge in full (in cash) of the Indebtedness and the termination of any and all commitments hereunder, as a result of any restatement of or adjustment to the financial statements of Sterling and any of its Subsidiaries (relating to the current or any prior fiscal period) or for any other miscalculation or error, Agent determines that the Applicable Margin and/or the Applicable Fee Percentages as calculated by Borrowers as of any applicable date of determination were inaccurate in any respect and a proper calculation thereof would have resulted in different pricing for any fiscal period, then (x) if the proper calculation thereof would have resulted in higher pricing for any such period, Borrowers shall automatically and retroactively be jointly and severally obligated to pay to Agent, promptly upon demand by Agent or the Majority Lenders, an amount equal to the excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period and, if the current fiscal period is affected thereby, the Applicable Margin and/or the Applicable Fee Percentages for the current period shall be adjusted based on such recalculation; and (y) if the proper calculation thereof would have resulted in lower pricing for such period, Agent and Lenders shall have no obligation to recalculate such interest or fees or to repay any interest or fees to the Borrowers.

12.

AGENT.

12.1 Appointment of Agent. Each Lender and the holder of each Note (if issued) irrevocably appoints and authorizes the Agent to act on behalf of such Lender or holder under this Agreement and the other Loan Documents and to exercise such powers hereunder and thereunder as are specifically delegated to Agent by the terms hereof and thereof, together with such powers as may be reasonably incidental thereto, including without limitation the power to execute or authorize the execution of financing or similar statements or notices, and other documents. In performing its functions and duties under this Agreement, the Agent shall act solely as agent of the Lenders and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for any Credit Party.

12.2 Deposit Account with Agent. Each Borrower authorizes Agent, in Agent’s sole discretion, upon notice to the Borrower Representative to charge its general deposit account(s), if any, maintained with the Agent for the amount of any principal, interest, or other amounts or costs due under this Agreement when the same become due and payable under the terms of this Agreement or the Notes.

12.3 Scope of Agent’s Duties. The Agent shall have no duties or responsibilities except those expressly set forth herein, and shall not, by reason of this Agreement or otherwise, have a fiduciary relationship with any Lender (and no implied covenants or other obligations shall be read into this Agreement against the Agent). None of Agent, its Affiliates nor any of their respective directors, officers, employees or agents shall be liable to any Lender for any action taken or omitted to be taken by it or them under this Agreement or any document executed pursuant hereto, or in connection herewith or therewith with the consent or at the request of the Majority Lenders (or all of the Lenders for those acts requiring consent of all of the Lenders) (except for its or their own willful misconduct or gross negligence), nor be responsible for or have any duties to ascertain, inquire into or verify (a) any recitals or warranties made by the Credit Parties or any Affiliate of the Credit Parties, or any officer thereof contained herein or therein, (b) the effectiveness, enforceability, validity or due execution of this Agreement or any document executed pursuant hereto or any security thereunder, (c) the performance by the Credit Parties of their respective obligations hereunder or thereunder, or (d) the satisfaction of any condition hereunder or thereunder, including without limitation in connection with the making of any Advance or the issuance of any Letter of Credit. Agent and its Affiliates shall be entitled to rely upon any certificate, notice, document or other communication (including any cable, telegraph, telex, facsimile transmission or oral communication) believed by it to be genuine and correct and to have been sent or given by or on behalf of a proper person. Agent may treat the payee of any Note as the holder thereof. Agent may employ agents and may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable to the Lenders (except as to money or property received by them or their authorized agents), for the negligence or misconduct of any such agent selected by it with reasonable care or for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

12.4 Successor Agent. Agent may resign as such at any time upon at least thirty (30) days prior notice to Borrower Representative and each of the Lenders. If Agent at any time shall resign or if the office of Agent shall become vacant for any other reason, Majority Lenders shall, by written instrument, appoint successor agent(s) (“Successor Agent”) satisfactory to such Majority Lenders and, so long as no Default or Event of Default has occurred and is continuing, to Borrower Representative (which approval shall not be unreasonably withheld or delayed); provided, however that any such successor Agent shall be a bank or a trust company or other financial institution which maintains an office in the United States, or a commercial bank organized under the laws of the United States or any state thereof, or any Affiliate of such bank or trust company or other financial institution which is engaged in the banking business, and shall have a combined capital and surplus of at least $500,000,000. Such Successor Agent shall thereupon become the Agent hereunder, as applicable, and Agent shall deliver or cause to be delivered to any successor agent such documents of transfer and assignment as such Successor Agent may reasonably request. If a Successor Agent is not so appointed or does not accept such appointment before the resigning Agent’s resignation becomes effective, the resigning Agent may appoint a temporary successor to act until such appointment by the Majority Lenders and, if applicable, Borrower Representative, is made and accepted, or if no such temporary successor is appointed as provided above by the resigning Agent, the Majority Lenders shall thereafter perform all of the duties of the resigning Agent hereunder until such appointment by the Majority Lenders and, if applicable, Borrower Representative, is made and accepted. Such Successor Agent shall succeed to all of the rights and obligations of the resigning Agent as if originally named. The resigning Agent shall duly assign, transfer and deliver to such Successor Agent all moneys at the time held by the resigning Agent hereunder after deducting therefrom its expenses for which it is entitled to be reimbursed hereunder. Upon such succession of any such Successor Agent, the resigning Agent shall be discharged from its duties and obligations, in its capacity as Agent hereunder, except for its gross negligence or willful misconduct arising prior to its resignation hereunder, and the provisions of this Article 12 shall continue in effect for the benefit of the resigning Agent in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

12.5 Credit Decisions. Each Lender acknowledges that it has, independently of Agent and each other Lender and based on the financial statements of Borrowers and such other documents, information and investigations as it has deemed appropriate, made its own credit decision to extend credit hereunder from time to time. Each Lender also acknowledges that it will, independently of Agent and each other Lender and based on such other documents, information and investigations as it shall deem appropriate at any time, continue to make its own credit decisions as to exercising or not exercising from time to time any rights and privileges available to it under this Agreement, any Loan Document or any other document executed pursuant hereto.

12.6 Authority of Agent to Enforce This Agreement. Each Lender, subject to the terms and conditions of this Agreement, grants the Agent full power and authority as attorney-in-fact to institute and maintain actions, suits or proceedings for the collection and enforcement of any Indebtedness outstanding under this Agreement or any other Loan Document and to file such proofs of debt or other documents as may be necessary to have the claims of the Lenders allowed in any proceeding relative to any Credit Party, or their respective creditors or affecting their respective properties, and to take such other actions which Agent considers to be necessary or desirable for the protection, collection and enforcement of the Notes, this Agreement or the other Loan Documents.

12.7 Indemnification of Agent. The Lenders agree (which agreement shall survive the expiration or termination of this Agreement) to indemnify the Agent and its Affiliates (to the extent not reimbursed by Borrowers, but without limiting any obligation of Borrowers to make such reimbursement), ratably according to their respective Percentages, from and against any and all claims, damages, losses, liabilities, costs or expenses of any kind or nature whatsoever (including, without limitation, reasonable fees and expenses of house and outside counsel) which may be imposed on, incurred by, or asserted against the Agent and its Affiliates in any way relating to or arising out of this Agreement, any of the other Loan Documents or the transactions contemplated hereby or any action taken or omitted by the Agent and its Affiliates under this Agreement or any of the Loan Documents; provided, however, that no Lender shall be liable for any portion of such claims, damages, losses, liabilities, costs or expenses resulting from the Agent’s or its Affiliate’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent and its Affiliates promptly upon demand for its ratable share of any reasonable out-of-pocket expenses (including, without limitation, reasonable fees and expenses of house and outside counsel) incurred by the Agent and its Affiliates 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 or any of the other Loan Documents, to the extent that the Agent and its Affiliates are not reimbursed for such expenses by Borrowers, but without limiting the obligation of Borrowers to make such reimbursement. Each Lender agrees to reimburse the Agent and its Affiliates promptly upon demand for its ratable share of any amounts owing to the Agent and its Affiliates by the Lenders pursuant to this Section, provided that, if the Agent or its Affiliates are subsequently reimbursed by Borrowers for such amounts, they shall refund to the Lenders on a pro rata basis the amount of any excess reimbursement. If the indemnity furnished to the Agent and its Affiliates under this Section shall become impaired as determined in the Agent’s reasonable judgment or Agent shall elect in its sole discretion to have such indemnity confirmed by the Lenders (as to specific matters or otherwise), Agent shall give notice thereof to each Lender and, until such additional indemnity is provided or such existing indemnity is confirmed, the Agent may cease, or not commence, to take any action. Any amounts paid by the Lenders hereunder to the Agent or its Affiliates shall be deemed to constitute part of the Indebtedness hereunder.

12.8 Knowledge of Default. It is expressly understood and agreed that the Agent shall be entitled to assume that no Default or Event of Default has occurred and is continuing, unless the officers of the Agent immediately responsible for matters concerning this Agreement shall have received a written notice from a Lender or a Borrower specifying such Default or Event of Default and stating that such notice is a “notice of default”. Upon receiving such a notice, the Agent shall promptly notify each Lender of such Default or Event of Default and provide each Lender with a copy of such notice and shall endeavor to provide such notice to the Lenders within three (3) Business Days (but without any liability whatsoever in the event of its failure to do so).

12.9 Agent’s Authorization; Action by Lenders. Except as otherwise expressly provided herein, whenever the Agent is authorized and empowered hereunder on behalf of the Lenders to give any approval or consent, or to make any request, or to take any other action on behalf of the Lenders (including without limitation the exercise of any right or remedy hereunder or under the other Loan Documents), the Agent shall be required to give such approval or consent, or to make such request or to take such other action only when so requested in writing by the Majority Lenders or the Lenders, as applicable hereunder. Action that may be taken by the Majority Lenders, any other specified Percentage of the Lenders or all of the Lenders, as the case may be (as provided for hereunder) may be taken (i) pursuant to a vote of the requisite percentages of the Lenders as required hereunder at a meeting (which may be held by telephone conference call), provided that Agent exercises good faith, diligent efforts to give all of the Lenders reasonable advance notice of the meeting, or (ii) pursuant to the written consent of the requisite percentages of the Lenders as required hereunder, provided that all of the Lenders are given reasonable advance notice of the requests for such consent.

12.10 Enforcement Actions by the Agent. Except as otherwise expressly provided under this Agreement or in any of the other Loan Documents and subject to the terms hereof, Agent will take such action, assert such rights and pursue such remedies under this Agreement and the other Loan Documents as the Majority Lenders or all of the Lenders, as the case may be (as provided for hereunder), shall direct; provided, however, that the Agent shall not be required to act or omit to act if, in the reasonable judgment of the Agent, such action or omission may expose the Agent to personal liability for which Agent has not been satisfactorily indemnified hereunder or is contrary to this Agreement, any of the Loan Documents or applicable law. Except as expressly provided above or elsewhere in this Agreement or the other Loan Documents, no Lender (other than the Agent, acting in its capacity as agent) shall be entitled to take any enforcement action of any kind under this Agreement or any of the other Loan Documents.

12.11 Collateral Matters.

(a) The Agent is authorized on behalf of all the Lenders, without the necessity of any notice to or further consent from the Lenders, from time to time to take any action with respect to any Collateral or the Collateral Documents which may be necessary to perfect and maintain a perfected security interest in and Liens upon the Collateral granted pursuant to the Loan Documents.

(b) The Lenders irrevocably authorize the Agent, in its reasonable discretion, to the full extent set forth in the post-amble to Section 13.10 hereof, (1) to release or terminate any Lien granted to or held by the Agent upon any Collateral (a) upon termination of the Revolving Credit Aggregate Commitment and payment in full of all Indebtedness payable under this Agreement and under any other Loan Document; (b) constituting property (including, without limitation, Equity Interests in any Person) sold or to be sold or disposed of as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction and including the property of any Subsidiary that is disposed of as permitted hereby) permitted in accordance with the terms of this Agreement; (c) constituting property in which a Credit Party owned no interest at the time the Lien was granted or at any time thereafter; or (d) if approved, authorized or ratified in writing by the Majority Lenders, or all the Lenders, as the case may be, as provided in Section 13.10; (2) to subordinate the Lien granted to or held by Agent on any Collateral to any other holder of a Lien on such Collateral which is permitted by Section 8.2(b) hereof; and (3) if all of the Equity Interests held by the Credit Parties in any Person are sold or otherwise transferred to any transferee other than a Borrower or a Subsidiary of a Borrower as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction) permitted in accordance with the terms of this Agreement, to release such Person from all of its obligations under the Loan Documents (including, without limitation, under any Guaranty). Upon request by the Agent at any time, the Lenders will confirm in writing the Agent’s authority to release particular types or items of Collateral pursuant to this Section 12.11(b).

12.12 Agents in their Individual Capacities. Comerica Bank and its Affiliates, successors and assigns shall each have the same rights and powers hereunder as any other Lender and may exercise or refrain from exercising the same as though such Lender were not the Agent. Comerica Bank and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, and generally engage in any kind of banking, trust, financial advisory or other business with the Credit Parties as if such Lender were not acting as the Agent hereunder, and may accept fees and other consideration therefor without having to account for the same to the Lenders.

12.13 Agent’s Fees. Until the Indebtedness has been repaid and discharged in full and no commitment to extend any credit hereunder is outstanding, Borrowers are obligated, on a joint and several basis to pay to the Agent, as applicable, any agency or other fee(s) set forth (or to be set forth from time to time) in the applicable Fee Letter on the terms set forth therein. The agency fees referred to in this Section 12.13 shall not be refundable under any circumstances.

12.14 Documentation Agent or other Titles. Any Lender identified on the facing page or signature page of this Agreement or in any amendment hereto or as designated with consent of the Agent in any assignment agreement as Lead Arranger, Documentation Agent, Syndications Agent or any similar titles, shall not have any right, power, obligation, liability, responsibility or duty under this Agreement as a result of such title other than those applicable to all Lenders as such. Without limiting the foregoing, the Lenders so identified shall not have or be deemed to have any fiduciary relationship with any Lender as a result of such title. Each Lender acknowledges that it has not relied, and will not rely, on the Lender so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

12.15 No Reliance on Agent’s Customer Identification Program.

(a) Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may relay on the Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the Patriot Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with Borrowers or any of their Subsidiaries, any of their respective Affiliates or agents, the Loan Documents or the transactions hereunder: (i) any identify verification procedures, (ii) any record keeping, (iii) any comparisons with government lists, (iv) any customer notices or (v) any other procedures required under the CIP Regulations or such other laws.

(b) Each Lender or assignee or participant of a Lender that is not organized under the laws of the United States or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA Patriot Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to provision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Administrative Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the Patriot Act and the applicable regulations: (x) within 10 days after the Effective Date, and (y) at such other times as are required under the Patriot Act.

13.

MISCELLANEOUS.

13.1 Accounting Principles. Where the character or amount of any asset or liability or item of income or expense is required to be determined or any consolidation or other accounting computation is required to be made for the purposes of this Agreement, it shall be done, unless otherwise specified herein, in accordance with GAAP.

13.2 Consent to Jurisdiction. The Borrowers, the Agent and Lenders hereby irrevocably submit to the non-exclusive jurisdiction of any United States Federal Court or Texas state court sitting in Dallas, Texas in any action or proceeding arising out of or relating to this Agreement or any of the Loan Documents and the Borrowers, Agent and Lenders hereby irrevocably agree that all claims in respect of such action or proceeding may be heard and determined in any such United States Federal Court or Texas state court. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or the Notes. Each Borrower irrevocably consents to the service of any and all process in any such action or proceeding brought in any court in or of the State of Texas by the delivery of copies of such process to it at the applicable addresses specified on the signature page hereto or by certified mail directed to such address or such other address as may be designated by it in a notice to the other parties that complies as to delivery with the terms of Section 13.6. Nothing in this Section shall affect the right of the Lenders and the Agent to serve process in any other manner permitted by law or limit the right of the Lenders or the Agent (or any of them) to bring any such action or proceeding against any Credit Party or any of their property in the courts with subject matter jurisdiction of any other jurisdiction. Each Borrower irrevocably waives any objection to the laying of venue of any such suit or proceeding in the above described courts.

13.3 Law of Texas. This Agreement, the Notes and, the other Loan Documents shall be governed by and construed and enforced in accordance with the laws of the State of Texas. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

13.4 Interest. Agent, Lenders, Borrowers and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither Borrowers, any other party to the Loan Documents nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Indebtedness shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully contracted for, charged, or received under applicable law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Agent and Lenders expressly disavow any intention to contract for, charge, or collect excessive unearned interest or finance charges in the event the maturity of any Indebtedness is accelerated. If (a) the maturity of any Indebtedness is accelerated for any reason, (b) any Indebtedness is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) Agent or any Lender or any other holder of any or all of the Indebtedness shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Indebtedness to an amount in excess of that permitted to be charged by applicable law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Indebtedness or, at such Lender’s or holder’s option, promptly returned to Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable law, Agent, Lenders, Borrowers (and any other payors thereof) shall to the greatest extent permitted under applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable law in order to lawfully contract for, charge, or receive the maximum amount of interest permitted under applicable Law. In the event applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code, provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As used in this section the term “applicable law” means the laws of the State of Texas or the laws of the United States of America, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future.

13.5 Closing Costs and Other Costs; Indemnification.

(a) Borrowers shall pay or reimburse, on a joint and several basis, (a) Agent and its Affiliates for payment of, on demand, all reasonable costs and expenses, including, by way of description and not limitation, reasonable in-house and outside attorney fees and advances, appraisal and accounting fees, lien search fees, and required travel costs, incurred by Agent and its Affiliates in connection with the commitment, consummation and closing of the loans contemplated hereby, or in connection with the administration or enforcement of this Agreement or the other Loan Documents (including the obtaining of legal advice regarding the rights and responsibilities of the parties hereto) or any refinancing or restructuring of the loans or Advances provided under this Agreement or the other Loan Documents, or any amendment or modification thereof requested by Borrowers, and (b) Agent and its Affiliates and each of the Lenders, as the case may be, for all stamp and other taxes and duties payable or determined to be payable in connection with the execution, delivery, filing or recording of this Agreement and the other Loan Documents and the consummation of the transactions contemplated hereby, and any and all liabilities with respect to or resulting from any delay in paying or omitting to pay such taxes or duties. Furthermore, all reasonable costs and expenses, including without limitation attorney fees, incurred by Agent and its Affiliates and, after the occurrence and during the continuance of an Event of Default, by the Lenders in revising, preserving, protecting, exercising or enforcing any of its or any of the Lenders’ rights against Borrowers or any other Credit Party, or otherwise incurred by Agent and its Affiliates and the Lenders in connection with any Event of Default or the enforcement of the loans (whether incurred through negotiations, legal proceedings or otherwise), including by way of description and not limitation, such charges in any court or bankruptcy proceedings or arising out of any claim or action by any person against Agent, its Affiliates, or any Lender which would not have been asserted were it not for Agent’s or such Affiliate’s or Lender’s relationship with Borrowers hereunder or otherwise, shall also be paid, on a joint and several basis, by Borrowers. All of said amounts required to be paid by Borrowers hereunder and not paid forthwith upon demand, as aforesaid, shall bear interest, from the date incurred to the date payment is received by Agent, at the Prime-based Rate, plus two percent (2%).

(b) Borrowers jointly and severally agree to indemnify and hold Agent and each of the Lenders (and their respective Affiliates) harmless from all loss, cost, damage, liability or expenses, including reasonable house and outside attorneys’ fees and disbursements (but without duplication of such fees and disbursements for the same services), incurred by Agent and each of the Lenders by reason of an Event of Default, or enforcing the obligations of any Credit Party under this Agreement or any of the other Loan Documents, as applicable, or in the prosecution or defense of any action or proceeding concerning any matter growing out of or connected with this Agreement or any of the Loan Documents, excluding, however, any loss, cost, damage, liability or expenses to the extent arising as a result of the gross negligence or willful misconduct of the party seeking to be indemnified under this Section 13.5(b), provided that, the Borrowers shall be obligated to reimburse Agent and the Lenders for only a single financial consultant selected by Agent in consultation with the Lenders.

(c) The Borrowers agree on a joint and several basis to defend, indemnify and hold harmless Agent and each Lender (and their respective Affiliates), and their respective employees, agents, officers and directors from and against any and all claims, demands, penalties, fines, liabilities, settlements, damages, costs or expenses of whatever kind or nature (including without limitation, reasonable attorneys and consultants fees, investigation and laboratory fees, environmental studies required by Agent or any Lender in connection with the violation of Hazardous Material Laws), court costs and litigation expenses, arising out of or related to (i) the presence, use, disposal, release or threatened release of any Hazardous Materials on, from or affecting any premises owned or occupied by any Credit Party in violation of or the non-compliance with applicable Hazardous Material Laws, (ii) any personal injury (including wrongful death) or property damage (real or personal) arising out of or related to such Hazardous Materials, (iii) any lawsuit or other proceeding brought or threatened, settlement reached or governmental order or decree relating to such Hazardous Materials, and/or (iv) complying or coming into compliance with all Hazardous Material Laws (including the cost of any remediation or monitoring required in connection therewith) or any other Requirement of Law; provided, however, that the Borrowers shall have no obligations under this Section 13.5(c) with respect to claims, demands, penalties, fines, liabilities, settlements, damages, costs or expenses to the extent arising as a result of the gross negligence or willful misconduct of the Agent or such Lender, as the case may be. The obligations of Borrowers under this Section 13.5(c) shall be in addition to any and all other obligations and liabilities Borrowers may have to Agent or any of the Lenders at common law or pursuant to any other agreement.

13.6 Notices.

(a)

Except as expressly provided otherwise in this Agreement (and except as provided in clause (b) below), all notices and other communications provided to any party hereto under this Agreement or any other Loan Document shall be in writing and shall be given by personal delivery, by mail, by reputable overnight courier or by facsimile and addressed or delivered to it at its address set forth on Schedule 13.6 or at such other address as may be designated by such party in a notice to the other parties that complies as to delivery with the terms of this Section 13.6 or posted to an E-System set up by or at the direction of Agent (as set forth below).

If such telephonic notice conflicts with any such confirmation, the terms of such telephonic notice shall control. Any notice given by the Agent or any Lender to the Borrower Representative shall be deemed to be a notice to all of the Credit Parties.

(b)

Unless otherwise agreed to in a writing by and among the parties to a particular communication, (i) notices and other communications sent to an email address shall be deemed received upon the sender’s receipt of an acknowledgment from the intended recipient (such as by the “return receipt requested” function, return email, or other written acknowledgment) and (ii) notices and other communications posted to any E-System shall be deemed received upon the deemed receipt by the intended recipient at its email address as described in the foregoing clause (i) of notification that such notice or other communication is available and identifying the website address therefore.

13.7 Further Action. Borrowers, from time to time, upon written request of Agent will make, execute, acknowledge and deliver or cause to be made, executed, acknowledged and delivered, all such further and additional instruments, and take all such further action as may reasonably be required to carry out the intent and purpose of this Agreement or the Loan Documents, and to provide for Advances under and payment of the Notes, according to the intent and purpose herein and therein expressed.

13.8 Successors and Assigns; Participations; Assignments.

(a) This Agreement shall be binding upon and shall inure to the benefit of the Borrowers and the Lenders and their respective successors and assigns.

(b) The foregoing shall not authorize any assignment by any Borrower of its rights or duties hereunder, and, except as otherwise provided herein, no such assignment shall be made (or be effective) without the prior written approval of the Lenders.

(c) No Lenders may at any time assign or grant participations in such Lender’s rights and obligations hereunder and under the other Loan Documents except (i) by way of assignment to any Eligible Assignee in accordance with clause (d) of this Section, (ii) by way of a participation in accordance with the provisions of clause (e) of this Section or (iii) by way of a pledge or assignment of a security interest subject to the restrictions of clause (f) of this Section (and any other attempted assignment or transfer by any Lender shall be deemed to be null and void).

(d) Each assignment by a Lender of all or any portion of its rights and obligations hereunder and under the other Loan Documents, shall be subject to the following terms and conditions:

(i)

each such assignment shall be made on a pro rata basis, and shall be in a minimum amount of the lesser of (x) Five Million Dollars ($5,000,000) or such lesser amount as the Agent shall agree and (y) the entire remaining amount of assigning Lender’s aggregate interest in the Revolving Credit (and participations in any outstanding Letters of Credit); provided however that, after giving effect to such assignment, in no event shall the entire remaining amount (if any) of assigning Lender’s aggregate interest in the Revolving Credit (and participations in any outstanding Letters of Credit) be less than $5,000,000; and

(ii)

the parties to any assignment shall execute and deliver to Agent an Assignment Agreement substantially (as determined by Agent) in the form attached hereto as Exhibit H (with appropriate insertions acceptable to Agent), together with a processing and recordation fee in the amount, if any, required as set forth in the Assignment Agreement (provided however that such Lender need not deliver an Assignment Agreement in connection with assignments to such Lender’s Affiliates or to a Federal Reserve Bank).

Until the Assignment Agreement becomes effective in accordance with its terms, and Agent has confirmed that the assignment satisfies the requirements of this Section 13.8, the Borrowers and the Agent shall be entitled to continue to deal solely and directly with the assigning Lender in connection with the interest so assigned. From and after the effective date of each Assignment Agreement that satisfies the requirements of this Section 13.8, the assignee thereunder shall be deemed to be a party to this Agreement, such assignee shall have the rights and obligations of a Lender under this Agreement and the other Loan Documents (including without limitation the right to receive fees payable hereunder in respect of the period following such assignment) and the assigning Lender shall relinquish its rights and be released from its obligations under this Agreement and the other Loan Documents.

Upon request, Borrowers shall execute and deliver to the Agent, new Note(s) payable to the order of the assignee in an amount equal to the amount assigned to the assigning Lender pursuant to such Assignment Agreement, and with respect to the portion of the Indebtedness retained by the assigning Lender, to the extent applicable, new Note(s) payable to the order of the assigning Lender in an amount equal to the amount retained by such Lender hereunder. The Agent, the Lenders and each Borrower acknowledges and agrees that any such new Note(s) shall be given in renewal and replacement of the Notes issued to the assigning lender prior to such assignment and shall not effect or constitute a novation or discharge of the Indebtedness evidenced by such prior Note, and each such new Note may contain a provision confirming such agreement.

(e) The Borrowers and the Agent acknowledge that each of the Lenders may at any time and from time to time, subject to the terms and conditions hereof, grant participations in such Lender’s rights and obligations hereunder (on a pro rata basis only) and under the other Loan Documents to any Person (other than a natural person or to any Borrower or any of Borrower’s Affiliates or Subsidiaries); provided that any participation permitted hereunder shall comply with all applicable laws and shall be subject to a participation agreement that incorporates the following restrictions:

(i)

such Lender shall remain the holder of its Notes hereunder (if such Notes are issued), notwithstanding any such participation;

(ii)

a participant shall not reassign or transfer, or grant any sub-participations in its participation interest hereunder or any part thereof; and

(iii)

such Lender shall retain the sole right and responsibility to enforce the obligations of the Credit Parties relating to the Notes and the other Loan Documents, including, without limitation, the right to proceed against any Guarantors, or cause the Agent to do so (subject to the terms and conditions hereof), and the right to approve any amendment, modification or waiver of any provision of this Agreement without the consent of the participant (unless such participant is an Affiliate of such Lender), except for those matters covered by Section 13.10(a) through (e) hereof (provided that a participant may exercise any of the approval rights granted above in this clause (iii) only on an indirect basis, acting through such Lender and the Credit Parties, Agent and the other Lenders may continue to deal directly with such Lender in connection with such Lender’s rights and duties hereunder). Notwithstanding the foregoing, however, in the case of any participation granted by any Lender hereunder, the participant shall not have any rights under this Agreement or any of the other Loan Documents against the Agent, any other Lender or any Credit Party; provided, however that the participant may have rights against such Lender in respect of such participation as may be set forth in the applicable participation agreement and all amounts payable by the Credit Parties hereunder shall be determined as if such Lender had not sold such participation. Each such participant shall be entitled to the benefits of Article 11 of this Agreement to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to clause (d) of this Section, provided that no participant shall be entitled to receive any greater amount pursuant to such the provisions of Article 11 than the issuing Lender would have been entitled to receive in respect of the amount of the participation transferred by such issuing Lender to such participant had no such transfer occurred and each such participant shall also be entitled to the benefits of Section 9.6 hereof as though it were a Lender, provided that such participant agrees to be subject to Section 10.3 hereof 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 its Notes, 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 such Lender from any of its obligations hereunder or substitute any such pledge or assignee for such Lender as a party hereto.

(g) The Agent shall maintain at its principal office a copy of each Assignment Agreement delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders, the Percentages of such Lenders and the principal amount of each type of Advance owing to each such Lender from time to time. The entries in the Register shall be conclusive evidence, absent manifest error, and the Borrowers, the Agent, and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Advances recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers or any Lender upon reasonable notice to the Agent and a copy of such information shall be provided to any such party on their prior written request. The Agent shall give prompt written notice to the Borrower Representative of the making of any entry in the Register or any change in such entry.

(h) Each Borrower authorizes each Lender to disclose to any prospective assignee or participant which has satisfied the requirements hereunder, any and all financial information in such Lender’s possession concerning the Credit Parties which has been delivered to such Lender pursuant to this Agreement, provided that each such prospective assignee or participant shall execute a confidentiality agreement consistent with the terms of Section 13.11 hereof or shall otherwise agree to be bound by the terms thereof.

(i) Nothing in this Agreement, the Notes or the other Loan Documents, expressed or implied, is intended to or shall confer on any Person other than the respective parties hereto and thereto and their successors and assignees and participants permitted hereunder and thereunder any benefit or any legal or equitable right, remedy or other claim under this Agreement, the Notes or the other Loan Documents.

13.9 Counterparts; Execution. This Agreement may be executed in several counterparts, and each executed copy shall constitute an original instrument, but such counterparts shall together constitute but one and the same instrument. This Agreement (and each other Loan Document) may be delivered by facsimile or electronic (e.g., .pdf or .tif file) transmission with the same effect as if an originally executed version of this Agreement (or such other Loan Document) had been personally delivered to each of the parties hereto, whether or not an original remains in existence.

13.10 Amendment and Waiver. No amendment or waiver of any provision of this Agreement or any other Loan Document, nor consent to any departure by any Credit Party therefrom, shall in any event be effective unless the same shall be in writing and signed by the Agent and the Majority Lenders (or by the Agent at the written request of the Majority Lenders) or, if this Agreement expressly so requires with respect to the subject matter thereof, by all Lenders (and, with respect to any amendments to this Agreement or the other Loan Documents, by any Credit Party or the Guarantors that are signatories thereto), and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by the Lender or Lenders affected thereby, do any of the following: (a) increase the stated amount of such Lender’s commitment hereunder, (b) reduce the principal of, or interest on, any outstanding Indebtedness or any Fees or other amounts payable hereunder, (c) postpone any date fixed for any payment of principal of, or interest on, any outstanding Indebtedness or any Fees or other amounts payable hereunder, (d) except as expressly permitted hereunder or under the Collateral Documents, release all or substantially all of the Collateral (provided that neither Agent nor any Lender shall be prohibited thereby from proposing or participating in a consensual or nonconsensual debtor-in-possession or similar financing), or release any material guaranty provided by any Person in favor of Agent and the Lenders, provided however that Agent shall be entitled, without notice to or any further action or consent of the Lenders, to release any Collateral which any Credit Party is permitted to sell, assign or otherwise transfer in compliance with this Agreement or the other Loan Documents or release any guaranty to the extent expressly permitted in this Agreement or any of the other Loan Documents (whether in connection with the sale, transfer or other disposition of the applicable Guarantor or otherwise), (e) terminate or modify any indemnity provided to the Lenders hereunder or under the other Loan Documents, except as shall be otherwise expressly provided in this Agreement or any other Loan Document, or (f) change the definitions of “Revolving Credit Percentage”, “Percentage”, “Interest Periods”, “Majority Lenders”, “Majority Revolving Credit Lenders”, Sections 10.2 or 10.3 hereof or this Section 13.10; provided, further, that notwithstanding the foregoing, the Revolving Credit Maturity Date may be postponed or extended, only with the consent of all of the Revolving Credit Lenders, and provided further, that no amendment, waiver or consent shall, unless in a writing signed by the Swing Line Lender, do any of the following: (x) reduce the principal of, or interest on, the Swing Line Note (y) postpone any date fixed for any payment of principal of, or interest on, the Swing Line Note or (z) alter the rights and duties of the Swing Line Lender hereunder and provided further, that no amendment, waiver or consent shall, unless in a writing signed by Issuing Lender affect the rights or duties of Issuing Lender under this Agreement or any of the other Loan Documents and no amendment, waiver, or consent shall, unless in a writing signed by the Agent affect the rights or duties of the Agent under this Agreement or any other Loan Document. All references in this Agreement to “Lenders” or “the Lenders” shall refer to all Lenders, unless expressly stated to refer to Majority Lenders (or the like).

The Agent shall, upon the written request of the Borrower Representative, execute and deliver to the Credit Parties such documents as may be necessary to evidence (1) the release of any Lien granted to or held by the Agent upon any Collateral: (a) upon termination of the Revolving Credit Aggregate Commitment and payment in full of all Indebtedness payable under this Agreement and under any other Loan Document; (b) which constitutes property (including, without limitation, Equity Interests in any Person) sold or to be sold or disposed of as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction and including the property of any Subsidiary that is disposed of as permitted hereby) permitted in accordance with the terms of this Agreement; (c) which constitutes property in which a Credit Party owned no interest at the time the Lien was granted or at any time thereafter; or (d) if approved, authorized or ratified in writing by the Majority Lenders, or all the Lenders, as the case may be, as provided in this Section 13.10; or (2) the release of any Person from its obligations under the Loan Documents (including without limitation the Guaranty) if all of the Equity Interests of such Person that were held by a Credit Party are sold or otherwise transferred to any transferee other than a Borrower or a Subsidiary of a Borrower as part of or in connection with any disposition (whether by sale, by merger or by any other form of transaction) permitted in accordance with the terms of this Agreement; provided that (i) Agent shall not be required to execute any such release or subordination agreement under clauses (1) or (2) above on terms which, in the Agent’s opinion, would expose the Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty or such release shall not in any manner discharge, affect or impair the Indebtedness or any Liens upon any Collateral retained by any Credit Party, including (without limitation) the proceeds of the sale or other disposition, all of which shall constitute and remain part of the Collateral.

13.11 Confidentiality. Each Lender agrees that it will not disclose without the prior consent of the Borrower Representative (other than to its employees, its Subsidiaries, another Lender, an Affiliate of a Lender or to its auditors or counsel) any information with respect to the Credit Parties which is furnished pursuant to this Agreement or any of the other Loan Documents; provided that any Lender may disclose any such information (a) as has become generally available to the public or has been lawfully obtained by such Lender from any third party under no duty of confidentiality to any Credit Party, (b) as may be required or appropriate in any report, statement or testimony submitted to, or in respect to any inquiry, by, any municipal, state or federal regulatory body having or claiming to have jurisdiction over such Lender, including the Board of Governors of the Federal Reserve System of the United States, the Office of the Comptroller of the Currency 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 respect to any summons or subpoena or in connection with any litigation, (d) in order to comply with any law, order, regulation, ruling or other requirement of law applicable to such Lender, and (e) to any prospective assignee or participant in accordance with Section 13.8(f) hereof.

13.12 Substitution of Lenders. If (a) any Lender has failed to fund its Revolving Credit Percentage of any Revolving Credit Advance, or to fund a Revolving Credit Advance to repay a Swing Line Advance or any Reimbursement Obligations, (b) the obligation of any Lender to make Eurodollar-based Advances has been suspended pursuant to Section 11.3 or 11.4, (c) any Lender has demanded compensation under Section 3.4(c), 11.5 or 11.6 or (d) any Lender has not approved an amendment, waiver or other modification of this Agreement, if such amendment or waiver has been approved by the Majority Lenders and the consent of such Lender is required (in each case, an “Affected Lender”), then the Agent or the Borrowers shall have the right to make written demand on the Affected Lender (with a copy to the Borrower Representative in the case of a demand by the Agent or with a copy to the Agent in the case of a demand by the Borrowers) to assign and the Affected Lender shall assign, to one or more financial institutions that comply with the provisions of Section 13.8 hereof (the “Purchasing Lender” or “Purchasing Lenders”) to purchase the Advances of the Revolving Credit and/or Swing Line, as the case may be, of such Affected Lender (including, without limitation, its participating interests in outstanding Swing Line Advances and Letters of Credit) and assume the commitment of the Affected Lender to extend credit under the Revolving Credit (including without limitation its obligation to purchase participations interest in Swing Line Advances and Letters of Credit) under this Agreement. The Affected Lender shall be obligated to sell its Advances of the Revolving Credit and/or Swing Line, as the case may be, and assign its commitment to extend credit under the Revolving Credit (including without limitation its obligations to purchase participations in Swing Line Advances and Letters of Credit) to such Purchasing Lender or Purchasing Lenders within ten (10) days after receiving notice from the Borrowers requiring it to do so, at an aggregate price equal to the outstanding principal amount thereof, plus unpaid interest accrued thereon up to but excluding the date of the sale. In connection with any such sale, and as a condition thereof, the Borrowers shall pay to the Affected Lender all fees accrued for its account hereunder to but excluding the date of such sale, plus, if demanded by the Affected Lender within ten (10) Business Days after such sale, (i) the amount of any compensation which would be due to the Affected Lender under Section 11.1 if the Borrowers had prepaid the outstanding Eurodollar-based Advances of the Affected Lender on the date of such sale and (ii) any additional compensation accrued for its account under Sections 3.4(c), 11.5 and 11.6 to but excluding said date. Upon such sale, the Purchasing Lender or Purchasing Lenders shall assume the Affected Lender’s commitment, and the Affected Lender shall be released from its obligations hereunder to a corresponding extent. If any Purchasing Lender is not already one of the Lenders, the Affected Lender, as assignor, such Purchasing Lender, as assignee, the Borrower Representative and the Agent, shall enter into an Assignment Agreement pursuant to Section 13.8 hereof, whereupon such Purchasing Lender shall be a Lender party to this Agreement, shall be deemed to be an assignee hereunder and shall have all the rights and obligations of a Lender with a Revolving Credit Percentage equal to its ratable share of the then applicable Revolving Credit Aggregate Commitment of the Affected Lender. In connection with any assignment pursuant to this Section 13.12, the Borrowers or the Purchasing Lender shall pay to the Agent the administrative fee for processing such assignment referred to in Section 13.8.

13.13 Withholding Taxes. If any Lender is not a “united states person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code, such Lender shall promptly (but in any event prior to the initial payment of interest hereunder or prior to its accepting any assignment under Section 13.8 hereof, as applicable) deliver to the Agent two executed copies of (i) Internal Revenue Service Form W-8BEN or any successor form specifying the applicable tax treaty between the United States and the jurisdiction of such Lender’s domicile which provides for the exemption from withholding on interest payments to such Lender, (ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that the income to be received by such Lender hereunder is effectively connected with the conduct of a trade or business in the United States or (iii) other evidence satisfactory to the Agent that such Lender is exempt from United States income tax withholding with respect to such income; provided, however, that such Lender shall not be required to deliver to Agent the aforesaid forms or other evidence with respect to Advances to Borrowers, if such Lender has assigned its entire interest hereunder (including its Revolving Credit Commitment Amount, any outstanding Advances hereunder and participations in Letters of Credit issued hereunder and any Notes issued to it by Borrowers), to an Affiliate which is incorporated under the laws of the United States or a state thereof, and so notifies the Agent. Such Lender shall amend or supplement any such form or evidence as required to insure that it is accurate, complete and non-misleading at all times. Promptly upon notice from the Agent of any determination by the Internal Revenue Service that any payments previously made to such Lender hereunder were subject to United States income tax withholding when made, such Lender shall pay to the Agent the excess of the aggregate amount required to be withheld from such payments over the aggregate amount actually withheld by the Agent. In addition, from time to time upon the reasonable request and the sole expense of Borrower, each Lender and the Agent shall (to the extent it is able to do so based upon applicable facts and circumstances), complete and provide Borrowers with such forms, certificates or other documents as may be reasonably necessary to allow Borrowers, as applicable, to make any payment under this Agreement or the other Loan Documents without any withholding for or on the account of any tax under Section 10.1(d) hereof (or with such withholding at a reduced rate), provided that the execution and delivery of such forms, certificates or other documents does not adversely affect or otherwise restrict the rights and benefits (including without limitation economic benefits) available to such Lender or the Agent, as the case may be, under this Agreement or any of the other Loan Documents, or under or in connection with any transactions not related to the transactions contemplated hereby.

13.14 Taxes and Fees. Should any tax (other than as a result of a Lender’s failure to comply with Section 13.13 or a tax based upon the net income or capitalization of any Lender or the Agent by any jurisdiction where a Lender or the Agent is or has been located), or recording or filing fee become payable in respect of this Agreement or any of the other Loan Documents or any amendment, modification or supplement hereof or thereof, Borrowers agrees to pay the same, together with any interest or penalties thereon arising from any Borrower’s actions or omissions, and agrees to hold the Agent and the Lenders harmless with respect thereto provided, however, that Borrowers shall not be responsible for any such interest or penalties which were incurred prior to the date that notice is given to the Credit Parties of such tax or fees. Notwithstanding the foregoing, nothing contained in this Section 13.14 shall affect or reduce the rights of any Lender or the Agent under Section 11.5 hereof.

13.15 WAIVER OF JURY TRIAL. THE LENDERS, THE AGENT AND THE BORROWERS KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTION OF ANY OF THEM. NEITHER THE LENDERS, THE AGENT NOR THE BORROWERS SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE LENDERS AND THE AGENT OR THE BORROWER EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

13.16 Patriot Act Notice. Pursuant to Section 326 of the USA Patriot Act, the Agent and the Lenders hereby notify the Credit Parties that if they or any of their Subsidiaries open an account, including any loan, deposit account, treasury management account, or other extension of credit with Agent or any Lender, the Agent or the applicable Lender will request the applicable Person’s name, tax identification number, business address and other information necessary to identify such Person (and may request such Person’s organizational documents or other identifying documents) to the extent necessary for the Agent and the applicable Lender to comply with the USA Patriot Act.

13.17 Complete Agreement; Conflicts. THIS AGREEMENT AND THE OTHER “LOAN AGREEMENTS” (AS DEFINED IN SECTION 26.02(A)(2) OF THE TEXAS BUSINESS & COMMERCE CODE, AS AMENDED) REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES, AND THIS AGREEMENT AND THE OTHER WRITTEN LOAN AGREEMENTS MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. In the event of any conflict between the terms of this Agreement and the other Loan Documents, this Agreement shall govern.

13.18 Severability. In case any one or more of the obligations of the Credit Parties under this Agreement, the Notes or any of the other Loan Documents shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining obligations of the Credit Parties shall not in any way be affected or impaired thereby, and such invalidity, illegality or unenforceability in one jurisdiction shall not affect the validity, legality or enforceability of the obligations of the Credit Parties under this Agreement, the Notes or any of the other Loan Documents in any other jurisdiction.

13.19 Table of Contents and Headings; Section References. The table of contents and the headings of the various subdivisions hereof are for convenience of reference only and shall in no way modify or affect any of the terms or provisions hereof and references herein to “sections,” “subsections,” “clauses,” “paragraphs,” “subparagraphs,” “exhibits” and “schedules” shall be to sections, subsections, clauses, paragraphs, subparagraphs, exhibits and schedules, respectively, of this Agreement unless otherwise specifically provided herein or unless the context otherwise clearly indicates.

13.20 Construction of Certain Provisions. If any provision of this Agreement or any of the Loan Documents refers to any action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person, whether or not expressly specified in such provision.

13.21 Independence of Covenants. Each covenant hereunder shall be given independent effect (subject to any exceptions stated in such covenant) so that if a particular action or condition is not permitted by any such covenant (taking into account any such stated exception), the fact that it would be permitted by an exception to, or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default.

13.22 Electronic Transmissions.

(a)

Each of the Agent, the Credit Parties, the Lenders, and each of their Affiliates is authorized (but not required) to transmit, post or otherwise make or communicate, in its sole discretion, Electronic Transmissions in connection with any Loan Document and the transactions contemplated therein. Each Borrower and each other Credit Party hereby acknowledges and agrees that the use of Electronic Transmissions is not necessarily secure and that there are risks associated with such use, including risks of interception, disclosure and abuse and each indicates it assumes and accepts such risks by hereby authorizing the transmission of Electronic Transmissions.

(b)

All uses of an E-System shall be governed by and subject to, in addition to Section 13.6 and this Section 13.22, separate terms and conditions posted or referenced in such E-System and related contractual obligations executed by the Agent, the Credit Parties and the Lenders in connection with the use of such E-System.

(c)

All E-Systems and Electronic Transmissions shall be provided “as is” and “as available”. None of the Agent or any of its Affiliates warrants the accuracy, adequacy or completeness of any E-Systems or Electronic Transmission, and each disclaims all liability for errors or omissions therein. No warranty of any kind is made by the Agent or any of its Affiliates in connection with any E Systems or Electronic Transmission, including any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects.

All terms, covenants, agreements, representations and warranties of the Credit Parties to any of the Loan Documents made herein or in any of the Loan Documents or in any certificate, report, financial statement or other document furnished by or on behalf of any Credit Party in connection with this Agreement or any of the Loan Documents shall be deemed to have been relied upon by the Lenders, notwithstanding any investigation heretofore or hereafter made by any Lender or on such Lender’s behalf, and those covenants and agreements of the Borrowers set forth in Section 13.5 hereof (together with any other indemnities of any Credit Party contained elsewhere in this Agreement or in any of the other Loan Documents) and of Lenders set forth in Section 12.7 hereof shall survive the repayment in full of the Indebtedness and the termination of any commitment to extend credit.

13.25 Joint and Several Liability.

(a)

Each of the Borrowers acknowledges and agrees that it is the intent of the parties that each such Borrower be primarily liable for the obligations as a joint and several obligor. It is the intention of the parties that with respect to liability of any Borrower hereunder arising solely by reason of its being jointly and severally liable for Advances and other extensions of credit taken by Borrower, the obligations of such Borrower shall be absolute, unconditional and irrevocable irrespective of:

(i)

any lack of validity, legality or enforceability of this Agreement or any Note as to any Borrower, as the case may be;

(ii)

the failure of any Lender or any holder of any Note:

(a) to enforce any right or remedy against any Borrower, as the case may be, or any other Person (including any Guarantor) under the provisions of this Agreement, such Note, or otherwise, or

(b) to exercise any right or remedy against any guarantor of, or collateral securing, any obligations;

(iii)

any change in the time, manner or place of payment of, or in any other term of, all or any of the Indebtedness, or any other extension, compromise or renewal of any Indebtedness;

102

(iv)

any reduction, limitation, impairment or termination of any Indebtedness with respect to any Borrower, as the case may be, for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and each of the Borrowers hereby waives any right to or claim of) any defense (other than the defense of payment in full of the Indebtedness) or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Indebtedness with respect to any Borrower, as the case may be;

(v)

any addition, exchange, release, surrender or nonperfection of any collateral, or any amendment to or waiver or release or addition of, or consent to departure from, any guaranty, held by any Lender or any holder of the Notes securing any of the Indebtedness; or

(vi)

any other circumstance which might otherwise constitute a defense (other than the defense of payment in full of the Indebtedness) available to, or a legal or equitable discharge of, any Borrower, as the case may be, any surety or any guarantor.

(b)

Each of the Borrowers agrees that its joint and several liability hereunder shall continue to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part) of any of the Indebtedness is rescinded or must be restored by any Lender or any holder of any Note, upon the insolvency, bankruptcy or reorganization of any Borrower, as the case may be, as though such payment had not been made;

(c)

Each of the Borrowers hereby expressly waives: (i) notice of the Lenders’ acceptance of this Agreement; (ii) notice of the existence or creation or non payment of all or any of the Indebtedness other than notices expressly provided for in this Agreement; (iii) presentment, demand, notice of dishonor, protest, and all other notices whatsoever other than notices expressly provided for in this Agreement; (iv) any claim or defense based on an election of remedies; and (v) all diligence in collection or protection of or realization upon the Indebtedness or any part thereof, any obligation hereunder, or any security for or guaranty of any of the foregoing.

(d)

No delay on any of the Lenders part in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by any of the Lenders of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action of any of the Lenders permitted hereunder shall in any way affect or impair any such Lenders’ rights or any Borrower’s Indebtedness under this Agreement.

103

(e)

Each of the Borrowers hereby represents and warrants to each of the Lenders that it now has and will continue to have independent means of obtaining information concerning the Borrowers’ affairs, financial condition and business. Lenders shall not have any duty or responsibility to provide any Borrower with any credit or other information concerning such Borrower’s affairs, financial condition or business which may come into the Lenders’ possession.

(f)

Each of the Borrowers represents and warrants (i) that the business operations of the Borrowers are interrelated and that the business operations of the Borrowers complement one another, and such entities have a common business purpose, and (ii) that, to permit their uninterrupted and continuous operations, such entities now require and will from time to time hereafter require funds and credit accommodations for general business purposes and that (iii) the proceeds of advances under the Revolving Credit, the Swing Line, and the other credit facilities extended hereunder will directly or indirectly benefit the Borrowers hereunder, severally and jointly, regardless of which Borrower receives part or all of the proceeds of such Advances.

(g)

Notwithstanding anything to the contrary contained herein, it is the intention of the Borrowers, Agent and the Lenders that the amount of the respective Borrowers’ obligations hereunder shall be in, but not in excess of, the maximum amount thereof not subject to avoidance or recovery by operation of applicable law governing bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors, dissolution, insolvency, fraudulent transfers or conveyances or other similar laws (collectively, “Applicable Insolvency Laws”). To that end, but only in the event and to the extent that the Borrowers’ respective obligations hereunder or any payment made pursuant thereto would, but for the operation of the foregoing proviso, be subject to avoidance or recovery under Applicable Insolvency Laws, the amount of the Borrowers’ respective obligations hereunder shall be limited to the largest amount which, after giving effect thereto, would not, under Applicable Insolvency Laws, render the Borrower’s respective obligations hereunder unenforceable or avoidable or subject to recovery under Applicable Insolvency Laws. To the extent any payment actually made hereunder exceeds the limitation contained in this Section 13.25(g), then the amount of such excess shall, from and after the time of payment by the Borrowers (or any of them), be reimbursed by the Lenders upon demand by such Borrowers. The foregoing proviso is intended solely to preserve the rights of the Agent and the Lenders hereunder against the Borrowers to the maximum extent permitted by Applicable Insolvency Laws and neither any Borrower nor any Guarantor nor any other Person shall have any right or claim under this Section 13.25(g) that would not otherwise be available under Applicable Insolvency Laws.
