Commitments

Section 2.01 Loans and Letters of Credit.

(a) Revolving Credit Loans. Each Lender severally agrees, on the terms and conditions of this Agreement, to make loans to the Borrower during the period from and including (i) the Closing Date or (ii) such later date that such Lender becomes a party to this

Revolving Credit Agreement – Page 22

Agreement as provided in Section 12.05(b), to and up to, but excluding, the Termination Date in an aggregate principal amount at any one time outstanding up to, but not exceeding, the amount of such Lender’s Revolving Credit Commitment as then in effect; provided, however, that the aggregate principal amount of all such Revolving Credit Loans by all Lenders hereunder at any one time outstanding together with the LC Exposure, and the outstanding Swing Line Loans shall not exceed the Aggregate Revolving Credit Commitments. Subject to the terms of this Agreement, during the period from the Closing Date to and up to, but excluding, the Termination Date, the Borrower may borrow, repay and reborrow the amount described in this Section 2.01(a).

(b) Swing Line Loans.

(i) Solely for ease of administration of the Revolving Credit Loans, the Swing Line Lender may, upon receipt of a notice required under Section 2.02(c) on the proposed date of funding, but shall not be required to, fund Base Rate Loans made in accordance with the provisions of this Agreement, bearing interest as set forth in Section 3.02(a)(i). The Swing Line Lender may, in its sole discretion and without conferring with the Lenders, make Swing Line Loans to the Borrower by entry of credits to the Borrower’s operating account(s) with the Swing Line Lender to cover checks which the Borrower has drawn or made against such account and shall notify the Administrative Agent of any overdrafts being advanced as Swing Line Loans. The Borrower hereby requests and authorizes the Swing Line Lender to make from time to time such Swing Line Loans by means of appropriate entries of such credits sufficient to cover checks then presented. The Borrower acknowledges and agrees that the making of such Swing Line Loans shall be subject in all respects to the provisions of this Agreement as if they were Swing Line Loans covered by a request under Section 2.02(c), including, without limitation, the limitations set forth in this Section 2.01 and the requirements that the applicable provisions of Section 6.01 (in the case of Swing Line Loans made on the Closing Date) and Section 6.02 be satisfied. All actions taken by the Swing Line Lender pursuant to the provisions of this Section 2.01(b) shall be conclusive and binding on the Borrower absent manifest error or such Swing Line Lender’s gross negligence or willful misconduct. The outstanding aggregate amount of Swing Line Loans advanced by the Swing Line Lender hereunder shall not exceed the Swing Line Commitment at any time. Each Lender with a Revolving Credit Commitment shall remain severally and unconditionally liable to fund its pro rata share (based upon each Lender’s Percentage Share) of such Swing Line Loans on each Settlement Date and, in the event the Swing Line Lender chooses not to fund all Base Rate Loans requested on any date, to fund its Percentage Share of the Base Rate Loans requested, subject to satisfaction of the provisions hereof relating to the making of Base Rate Loans. Prior to each Settlement, all payments or repayments of the principal of, and interest on, Swing Line Loans shall be credited to the account of the Swing Line Lender. The Borrower shall have the right, at its election, to prepay the outstanding amount of the Swing Line Loans, as a whole or in part, at any time without penalty or premium.

(ii) The Lenders with Revolving Credit Commitments shall effect Settlements on (A) the Business Day immediately following any day which the Swing Line Lender gives written notice to the Administrative Agent to effect a Settlement, (B) the Business Day immediately following the Swing Line Lender’s or the Administrative Agent’s becoming aware of the existence of any Default, (C) the Termination Date, (D) any date on which the

Revolving Credit Agreement – Page 23

Borrower wishes to convert a Swing Line Loan into a Revolving Credit Loan, and (E) in any event, on the first Business Day of each calendar quarter for the immediately preceding calendar quarter (each such date, a “Settlement Date”). One Business Day prior to each such Settlement Date, the Administrative Agent shall give notice by facsimile or telecopier to the Lenders with Revolving Credit Commitments of (1) the respective outstanding amount of Revolving Credit Loans made by each Lender as at the close of the prior Business Day, and (2) the amount that any Lender, as applicable (a “Settling Lender”), shall pay to effect a settlement (a “Settlement Amount”). A statement of the Administrative Agent submitted to the Lenders with Revolving Credit Commitments with respect to any amounts owing hereunder shall be PRIMA FACIE evidence of the amount due and owing. Each Settling Lender shall, not later than 11:00 a.m. (Central Time) on each Settlement Date, effect a wire transfer of immediately available funds to the Administrative Agent, for the benefit of the Swing Line Lender, at the Administrative Agent’s Principal Office in the amount of such Lender’s Settlement Amount. All funds advanced by any Lender with a Revolving Credit Commitment as a Settling Lender pursuant to this Section 2.01(b) shall for all purposes be treated as a Base Rate Loan by that Lender (in place of the Swing Loan Lender) to the Borrower and all such funds so advanced shall be treated as a payment in full of such amount by the Borrower under its Swing Line Loan.

(iii) Subject to the Settling Lender’s receipt of the notice required pursuant to Section 2.01(b)(ii), the Administrative Agent may (unless notified to the contrary by any Settling Lender by 11:00 a.m. (Central Time) one Business Day prior to the Settlement Date) assume that each Settling Lender has made available (or will make available by the time specified in Section 2.01(b)(ii)) to the Administrative Agent its Settlement Amount, and the Administrative Agent may (but shall not be required to), in reliance upon such assumption, effect Settlements. If the Settlement Amount of such Settling Lender is made available to the Administrative Agent on a date after such Settlement Date, such Settling Lender shall pay the Administrative Agent, for the benefit of the Swing Line Lender, on demand an amount equal to the product of (A) the average, computed for the period referred to in clause (C) below, of the weighted average annual interest rate paid by the Administrative Agent for federal funds acquired by the Administrative Agent during each day included in such period times (B) such Settlement Amount times (C) a fraction, the numerator of which is the number of days that elapse from and including such Settlement Date to but not including the date on which such Settlement Amount shall become immediately available to the Administrative Agent, and the denominator of which is 360. Upon payment of such amount such Settling Lender shall be deemed to have delivered its Settlement Amount on the Settlement Date and shall become entitled to interest payable by the Borrower with respect to such Settling Lender’s Settlement Amount as if such share were delivered on the Settlement Date. If such Settlement Amount is not in fact made available to the Administrative Agent by such Settling Lender within three Business Days of such Settlement Date, the Administrative Agent shall be entitled to recover such amount from the Borrower, with any unpaid interest thereon at the Base Rate.

(iv) After any Settlement Date, any payment by the Borrower of Swing Line Loans hereunder shall be allocated pro rata among the Lenders with Revolving Credit Commitments, in accordance with such Lender’s Percentage Share.

(v) If, prior to the making of a Revolving Credit Loan pursuant to clause (ii) of this Section 2.01(b), a Default has occurred and is continuing, each Lender with a

Revolving Credit Agreement – Page 24

Revolving Credit Commitment shall, on the date such Revolving Credit Loan was to have been made, purchase an undivided participating interest in the outstanding Swing Line Loans in an amount equal to its Percentage Share of such Swing Line Loans. Each Lender with a Revolving Credit Commitment will immediately transfer to the Administrative Agent, for the benefit of the Swing Line Lender, in immediately available funds, the amount of its participation and upon receipt thereof the Administrative Agent will deliver to such Lender a Swing Line participation certificate dated the date of receipt of such funds and in such amount.

(vi) Whenever, at any time after the Administrative Agent has received from any Lender with a Revolving Credit Commitment such Lender’s participating interest in the Swing Line Loans pursuant to clause (v) above, the Administrative Agent receives any payment on account thereof, the Administrative Agent will distribute to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded) in like funds as received; provided, however, that in the event that such payment received by the Administrative Agent is required to be returned, such Lender will return to the Administrative Agent any portion thereof previously distributed by the Administrative Agent to it in like funds as such payment is required to be returned by the Administrative Agent.

(vii) Each Lender’s obligation to purchase participating interests pursuant to clause (v) above 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 Lender may have against the Administrative Agent, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default; (C) any adverse change in the condition (financial or otherwise) of the Borrower or any other Person; (D) any breach of this Agreement by the Borrower or any other Lender or the Administrative Agent; or (E) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(c) Letters of Credit. During the period from and including the Closing Date to, but excluding, the date 30 days prior to the Termination Date, the Issuing Bank, as issuing bank for the Lenders with Revolving Credit Commitments, agrees to extend credit for the account of the Borrower or any Guarantor (other than Holdings) at any time and from time to time by issuing, renewing, extending or reissuing Letters of Credit; provided however, the LC Exposure at any one time outstanding shall not exceed the lesser of (i) the LC Commitment or (ii) the Aggregate Revolving Credit Commitments, as then in effect, minus the aggregate principal amount of all Revolving Credit Loans, Swing Line Loans and the LC Exposure then outstanding. The Lenders with Revolving Credit Commitments shall participate in such Letters of Credit according to their respective Percentage Shares. Each of the Letters of Credit shall (i) be issued by the Issuing Bank, (ii) contain such terms and provisions as are reasonably required by the Issuing Bank, (iii) be for the account of the Borrower or any Guarantor (other than Holdings) and (iv) expire not later than five Business Days prior to the Termination Date.

(d) Limitation on Types of Loans. Subject to the other terms and provisions of this Agreement, at the option of the Borrower, the Loans may be Base Rate Loans or LIBOR Loans; provided that, without the prior written consent of the Required Lenders, no more than 10 LIBOR Loans may be outstanding at any time.

In accordance with Section 2.04(d), the amount of the Aggregate Revolving Credit Commitments may be so increased either by having one or more New Lenders that have been approved by the Borrower become Lenders and/or by having any one or more of the then existing Lenders (at their respective election in their sole discretion) increase the amount of their Commitments (“Increasing Lenders”), provided that (i) the Revolving Credit Commitment of any New Lender shall not be less than $5,000,000 and the sum of the Commitments of the New Lenders and the increases in the Commitments of the Increasing Lenders shall be in an aggregate amount of not less than $5,000,000 (and, if in excess thereof, in integral multiples of $1,000,000); (ii) the aggregate amount of all the increases in the Aggregate Revolving Credit Commitments pursuant to this Section 2.04 shall not exceed $100,000,000 (provided however, the Administrative Agent shall have consented in its sole discretion to the utilization of the last $5,000,000 of the amount described in this clause (ii)); (iii) the Borrower, each New Lender and/or each Increasing Lender shall have executed and delivered to the Administrative Agent a commitment and acceptance (the “Commitment and Acceptance”) substantially in the form of Exhibit C hereto, and the Administrative Agent shall have accepted and executed the same, (iv) if requested by the Administrative Agent, the Borrower shall have delivered to the Administrative Agent opinions of counsel (substantially similar to the forms of opinions provided for in Section 6.01(f), modified to apply to the increase in the Commitments and Commitment and Acceptance executed and delivered in connection therewith); (v) the Guarantors shall have consented in writing to the new Commitments or increases in Commitments (as applicable) and shall have agreed that their Guaranty Agreement continues in full force and effect, and (vi) the Borrower, each New Lender and/or each Increasing Lender shall otherwise have executed and delivered such other instruments and documents as the Administrative Agent shall have reasonably requested in connection with such new Commitment

Revolving Credit Agreement – Page 28

or increase in the Commitment (as applicable). The form and substance of the documents required under clauses (iii) through (vi) above shall be reasonably acceptable to the Administrative Agent. The Administrative Agent shall provide written notice to all of the Lenders hereunder of the admission of any New Lender or the increase in the Commitment of any Increasing Lender hereunder and shall furnish to each of the Lenders copies of the documents required under clause (iii), (iv), (v) and (vi) above.

(b) Upon the effective date of any increase in the Aggregate Revolving Credit Commitments pursuant to the provisions hereof (such date hereinafter referred to as the “Increase Date”), which Increase Date shall be mutually agreed upon by the Borrower, each New Lender, each Increasing Lender and the Administrative Agent, each New Lender and/or Increasing Lender shall make a payment to the Administrative Agent in an amount sufficient, upon the application of such payments by all New Lenders and Increasing Lenders to the reduction of the outstanding Loans held by the Lenders (including the Increasing Lenders) to cause the principal amount outstanding under the Loans made by each Lender to be equal to each Lender’s Percentage Share of the Aggregate Revolving Credit Commitments as so increased as described herein. The Borrower hereby irrevocably authorizes each New Lender and/or each Increasing Lender to fund to the Administrative Agent the payment required to be made pursuant to the immediately preceding sentence for application to the reduction of the outstanding Loans held by the other Lenders, and each such payment shall constitute a Loan hereunder. If, as a result of the repayment of the Loans provided for in this Section 2.04(b), any payment of a LIBOR Loan occurs on a day which is not the last day of the applicable Interest Period, the Borrower will pay to the Administrative Agent for the benefit of any of the Lenders (including any Increasing Lender to the extent of LIBOR Loans held by such Increasing Lender prior to such Increase Date) holding a LIBOR Loan any loss or cost incurred by such Lender resulting therefrom in accordance with Section 5.04. Upon the Increase Date, all Loans outstanding hereunder (including any Loans made by the New Lenders and/or Increasing Lenders on the Increase Date) shall be Base Rate Loans, subject to the Borrower’s right to convert the same to LIBOR Loans on or after such date in accordance with the provisions of Section 2.02.

(c) Upon the Increase Date and the making of the Revolving Credit Loans by the New Lenders and/or Increasing Lenders in accordance with the provisions of Section 2.04(b), each New Lender and/or each Increasing Lender shall also be deemed to have irrevocably and unconditionally purchased and received without recourse or warranty, from the Lenders with Revolving Credit Commitments immediately prior to the Increase Date, an undivided interest and participation in any Letter of Credit and Swing Line Loan, as applicable, then outstanding, ratably, such that each Lender (including each New Lender) with Revolving Credit Commitments holds a participation interest in each such Letter of Credit and Swing Line Loan, as applicable, in proportion to such Lender’s Percentage Share.

(d) Upon the notice by the Borrower to the Administrative Agent pursuant to Section 2.04(a) hereof, each of the then existing Lenders shall have the right (at such Lender’s election) to increase its Commitment by an amount equal to such Lender’s Percentage Share of the proposed increase in the Aggregate Revolving Credit Commitments. If less than all of the proposed increase in Aggregate Revolving Credit Commitments is elected by the existing Lenders, then any of the then existing Lenders shall have the right to increase its Commitment in an amount greater than such Lender’s Percentage Share of the proposed increase in the Aggregate

Revolving Credit Agreement – Page 29

Revolving Credit Commitments with the Administrative Agent’s approval. If the entire amount of the proposed increase in Aggregate Revolving Credit Commitments is still not obtained, the Borrower may with the Administrative Agent’s cooperation add New Lenders, such New Lenders to be reasonably acceptable to the Administrative Agent, with new Commitments which when added to the increase in Commitments of the Increasing Lenders, shall equal the requested increase in the Aggregate Revolving Credit Commitments. In the event the sum of each New Lender’s Commitment and the increase in each Increasing Lender’s Commitment is less than the requested increase in the Aggregate Revolving Credit Commitments, the Borrower may elect to accept the increase in the Aggregate Revolving Credit Commitments to be equal to such lesser amount. Notwithstanding anything to the contrary, Administrative Agent shall not be liable for any failure to obtain Increasing Lenders or New Lenders hereunder or any failure to increase the Aggregate Revolving Credit Commitments by the amount so requested by the Borrower pursuant to Section 2.04(a).

(e) Nothing contained herein shall constitute, or otherwise be deemed to be a commitment or agreement on the part of any Lender to increase its Commitment hereunder at any time. No Lender (except only for itself) shall have the right to decline Borrower’s request pursuant to Section 2.04(a) for an increase in the Aggregate Revolving Credit Commitments.

Section 2.05 Fees.

(a) Commitment Fee. The Borrower shall pay to the Administrative Agent, for the account of each Lender holding a Revolving Credit Commitment, a commitment fee on the daily average unused amount of the Aggregate Revolving Credit Commitments for the period from and including the Closing Date up to, but excluding, the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Termination Date at a rate per annum equal to the applicable per annum percentage set forth at the appropriate intersection in the table shown below, based on the Leverage Ratio on the most recent Determination Date:


	Commitment
Leverage Ratio	Fee Percentage
<3.00:1.00		0.25	%
³ 3.00:1.00 and <3.50:1.00		0.25	%
³ 3.50:1.00 and <4.00:1.00		0.25	%
³ 4.00:1.00 and <4.50:1.00		0.375	%
³ 4.50:1.00		0.50	%

The commitment fee percentage shall be established as of each Determination Date beginning with the Initial Determination Date. Any change in the commitment fee percentage following each Determination Date shall be determined based upon the information and computations set forth in the financial statements and Compliance Certificate furnished to the Administrative Agent pursuant to Section 8.01, subject to review and approval of such computations by the Administrative Agent. Each change in the commitment fee percentage shall be effective as of the first day of the calendar month following each Determination Date and shall remain in effect until the date that is the first day of the calendar month following the next Determination Date for which a change in the commitment fee percentage occurs; provided, however; if the

Revolving Credit Agreement – Page 30

Borrower shall fail to deliver any required financial statements or Compliance Certificate within the time period required by Section 8.01, the commitment fee percentage shall be the highest percentage amount set forth in the above table for the period beginning on the relevant Determination Date and ending on the date that the appropriate financial statements and Compliance Certificate are so delivered. Notwithstanding the foregoing, during the period beginning on the Closing Date and ending on the Initial Determination Date, the commitment fee percentage shall be 0.25%. Accrued commitment fees shall be payable quarterly in arrears on each Quarterly Date and on the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Termination Date. For purposes of computing the commitment fees payable hereunder, outstanding Swing Line Loans shall be disregarded.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay the Administrative Agent, for the account of each Lender holding a Revolving Credit Commitment, commissions for issuing the Letters of Credit on the daily average outstanding of the maximum liability of the Issuing Bank existing from time to time under such Letter of Credit (calculated separately for each Letter of Credit) at the rate per annum equal to (x) with respect to Closure/Post-Closure Letters of Credit for landfills with remaining permitted lives expiring after the Termination Date, 75% of the Applicable Margin in effect from time to time for Letters of Credit, and (y) with respect to all other Letters of Credit, the Applicable Margin in effect from time to time for Letters of Credit, provided that each Letter of Credit shall bear a minimum commission of $500. Each Letter of Credit shall be deemed to be outstanding up to the full undrawn face amount of the Letter of Credit until the Issuing Bank has received the canceled Letter of Credit or a written cancellation of the Letter of Credit from the beneficiary of such Letter of Credit in form and substance acceptable to the Issuing Bank, or for any reductions in the amount of the Letter of Credit (other than from a drawing), written notification from the beneficiary of such Letter of Credit. Such commissions are payable quarterly in arrears on each Quarterly Date and upon cancellation or expiration of each such Letter of Credit.

(ii) In addition to the foregoing, the Borrower shall pay to the Issuing Bank, for its own account, (A) a fronting fee equal to 0.125% per annum of the face amount of each Letter of Credit issued, which fee is due and payable on the date of any renewal or increase of such Letter of Credit and (B) amendment, transfer, negotiating and other fees in accordance with the Issuing Bank’s then current fee policy generally applicable to letters of credit of the same or similar type issued by the Issuing Bank.

(c) The Borrower shall pay such other fees as are set forth in the Fee Letter in the manner and on the dates specified therein to the extent not paid prior to the Closing Date.

Section 2.06 Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender.

Revolving Credit Agreement – Page 31

Section 2.07 Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Credit Loan on the Termination Date, (ii) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each LIBOR Loan on the last day of the Interest Period applicable to such Loan and (iii) to the Swing Line Lender the then unpaid principal amount of each Swing Line Loan on the earlier of the Termination Date and the day that is at least seven Business Days after such Swing Line Loan is made; provided that on each date that a Revolving Credit Loan is made, the Borrower shall repay all Swing Line Loans then outstanding.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to clause (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in in the form of Exhibit D attached hereto. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 12.05) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.08 Prepayments.

(a) Voluntary Prepayments. The Borrower may prepay the Base Rate Loans upon not less than one Business Day’s prior notice to the Administrative Agent (which shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least $500,000 or any whole multiple of $100,000 or, if less, the remaining aggregate principal balance outstanding on the Loans) and shall be irrevocable and effective only upon receipt by the Administrative Agent, provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on the same conditions as for

Revolving Credit Agreement – Page 32

Base Rate Loans (except that prior notice to the Administrative Agent shall be not less than three Business Days for LIBOR Loans and the amount of the prepayment shall be at least $1,000,000 or any whole multiple of $500,000 or if less, the remaining aggregate principal balance outstanding on the Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.04.

(b) Mandatory Prepayments.

(i) Revolving Credit Commitment Reductions. If, after giving effect to any termination or reduction of the Aggregate Revolving Credit Commitments pursuant to Section 2.03(b) or 2.03(c), the outstanding aggregate principal amount of the Revolving Credit Loans and Swing Line Loans, plus the LC Exposure, exceeds the Aggregate Revolving Credit Commitments, the Borrower shall (i) prepay the Revolving Credit Loans and Swing Line Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to the date of such prepayment and (ii) if any excess remains after prepaying all of the Revolving Credit Loans and Swing Line Loans because of LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b) hereof.

(ii) Upon Transfers and Issuances of Equity. The Borrower shall, and shall cause any Subsidiary to, pay an amount equal to (A) 100% of the net cash proceeds received from any Transfers, based on the greater of the net book value of the Property sold or the net proceeds received, provided, that, with respect to net cash proceeds received from a Transfer permitted under Section 9.17(i), the Borrower is not required to make a prepayment hereunder so long as such proceeds have been applied to the purchase of replacement Property as described in Section 9.17(i) or may be otherwise permitted pursuant to Section 9.17(iii), (B) 50% of the excess net cash proceeds received from any issuance by Borrower of any Debt or by its Subsidiaries of any Subordinated Debt, and (C) 50% of the excess net cash proceeds received from any issuance by Borrower or its Subsidiaries of common stock, other than any common stock issued to Ares. Prepayments made pursuant to this clause (ii) shall be applied first, to the Revolving Credit Loans, and second, as cash collateral. Upon the occurrence of any event requiring a mandatory prepayment to the Revolving Credit Loans pursuant to this Section 2.08(b)(ii) other than the issuance by Borrower of the Senior Unsecured Debt in connection with an initial public offering consummated on or about the Closing Date, the Aggregate Revolving Credit Commitments shall automatically reduce by an amount equal to such net cash proceeds received in connection with the transactions described in clauses (A) and (B) above. Notwithstanding the foregoing, the Borrower may elect to provide cash collateral in lieu of the prepayment required pursuant to this clause (ii) to the extent any LIBOR Loans are outstanding until termination of the applicable Interest Period so long as no Default has occurred and is continuing.

(iii) Generally. Prepayments permitted or required under this Section 2.08 shall be without premium or penalty, except as required under Section 5.04 for prepayment of LIBOR Loans. Any prepayments on the Revolving Credit Loans may be reborrowed subject to the then effective Aggregate Revolving Credit Commitments. Any voluntary prepayments shall be applied to the Revolving Credit Loans as specified by Borrower.

Revolving Credit Agreement – Page 33

Together with any prepayments made hereunder, the accrued interest on the principal amount so prepaid shall be due and payable on the date of such prepayment.

(iv) Transfers of Non-Core Assets. The Borrower shall, and shall cause any Guarantor or Subsidiary to, apply an amount equal to 100% of the net cash proceeds received from any Transfers of the type referred to in Section 9.17(iv) to first, the Revolving Credit Loans, provided such prepayment shall not cause a reduction in the Aggregate Revolving Credit Commitments and second, promptly provide cash collateral. Notwithstanding the foregoing, the Borrower may elect to provide cash collateral in lieu of the prepayment required pursuant to this clause (iv) to the extent any LIBOR Loans are outstanding until termination of the applicable Interest Period so long as no Default has occurred and is continuing.

Section 2.09 Assumption of Risks. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank (except in the case of gross negligence or willful misconduct on the part of the Issuing Bank or any of its employees), nor any Lender shall be responsible for the validity, sufficiency (except for the sufficiency on their face) or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency (except for the sufficiency on their face) of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with the underlying conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank’s control or the control of the Issuing Bank’s correspondents. In addition, neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or any Lender’s rights or powers hereunder or under the Letter of Credit Agreements or this Agreement, all of which rights shall be cumulative. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to comply with the terms of the applicable Letter of Credit, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower in the absence of gross negligence or willful misconduct on the part of any such Person.

Section 2.10 Obligation to Reimburse and to Prepay.

(a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Administrative Agent within two Business Days after notice of any

Revolving Credit Agreement – Page 34

such disbursement is received by the Borrower, the amount of each such disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of the Letter of Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans (but in no event to exceed the Maximum Rate) through the second Business Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed the Maximum Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. Subject to Section 12.11, the obligations of the Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit, or any of the other Loan Documents; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit, or any of the other Loan Documents; (iii) the existence of any claim, set-off, defense or other rights which the Borrower or any Guarantor, if applicable, may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Administrative Agent, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the other Loan Documents, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient (so long as it is not insufficient on its face) or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft or certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank, except to the extent the Borrower or any Subsidiary actually recovers (net of costs and expenses) any proceeds (net of any expenses incurred for such recovery) for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct.

(b) In the event of the occurrence of any Event of Default, a payment or prepayment pursuant to Section 2.08(b) or the maturity of the Loans, whether by acceleration or otherwise, an amount equal to the LC Exposure (or the excess in the case of Section 2.08(b)), shall be deemed to be forthwith due and owing by the Borrower to the Administrative Agent as of the date of any such occurrence; and the Borrower’s obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the

Revolving Credit Agreement – Page 35

Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Administrative Agent on behalf of the Issuing Bank and the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and the Borrower hereby grants to and by its deposit with the Administrative Agent grants to the Administrative Agent a security interest in such cash collateral. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement or the other Loan Documents, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased.

(c) Each Lender with a Revolving Credit Commitment severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank an amount equal to such Lender’s Percentage Share of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.10.

(d) Notwithstanding anything to the contrary contained herein, subject to availability under the Swing Line Commitment, to the extent the Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit within two Business Days after notice of such disbursement has been received by the Borrower, the amount of such Letter of Credit reimbursement obligation shall automatically be funded by the Swing Line Lender as a Swing Line Loan hereunder and used by the Swing Line Lender to pay such Letter of Credit reimbursement obligation. To the extent the funding of such Letter of Credit reimbursement obligation as a Swing Line Loan would cause the aggregate amount of all Swing Line Loans outstanding to exceed the Swing Line Commitment or the Swing Line Lender does not desire to make a Swing Line Loan for such purpose, such Letter of Credit reimbursement obligation shall not be funded as a Swing Line Loan, but instead shall be funded as a Revolving Credit Loan.

Section 2.11 Lending Offices. The Loans of each Type made by each Lender shall be made and maintained at such Lender’s Applicable Lending Office for Loans of such Type.

If an Event of Default under Section 10.01(a) occurs, the operation of this Section 3.02(b) shall be automatic, but if the only Events of Default are Events of Default other than under Section 10.01(a), the operation of this Section 3.02(b) shall require the election of the Required Lenders to accrue interest at the Post-Default Rate.

Payments; Pro Rata Treatment; Computations; Etc.

Section 4.01 Payments. Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower under this Agreement and the Letter of Credit Agreements shall be made in Dollars, in immediately available funds, to the Administrative Agent at such account as the Administrative Agent shall specify by notice to the Borrower from time to time, not later than 11:00 a.m. (Central time) on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim. Each payment received by the Administrative Agent under this Agreement for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of “Interest Period”, if the due date of any payment under this Agreement would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to the Administrative Agent of any principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Loans to which such payment shall apply. In the absence of such notice the Administrative Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans.

Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein each Lender agrees that: (i) each borrowing from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their Percentage Share, each payment of commitment fee or other fees under Section 2.05(a) and Section 2.05(b)(i) shall be made for account of the Lenders pro rata in accordance with their Percentage Share, and each termination or reduction of the amount of the Aggregate Revolving Credit Commitments under Section 2.03(b) (subject to the last sentence thereof) shall be applied to the Commitment of each Lender, pro rata according to the amounts of its respective Commitment; (ii) each payment of principal of Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Lenders; and (iii) each payment of interest on Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; and (iv) each reimbursement by the Borrower of disbursements under the Letters of Credit shall be made for account of the Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective Lender.

Section 4.03 Computations. Interest on all LIBOR Loans shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Maximum Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. All computations of interest on Base Rate Loans

Revolving Credit Agreement – Page 38

and fees shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day).

Section 4.04 Non-receipt of Funds by the Administrative Agent.

(a) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Loan or Letters of Credit that such Lender will not make available to the Administrative Agent such Lender’s share of such Loan or Letters of Credit, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Sections 2.01(b), 2.02(f) and 2.10(c) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Loan or Letters of Credit available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Loan or Letters of Credit to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Loan or Letters of Credit. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

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

Section 4.05 Set-off, Sharing of Payments, Etc. (a) The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Lender may otherwise have, each Lender, the Issuing Bank, and each of their respective Affiliates shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in

Revolving Credit Agreement – Page 39

whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Issuing Bank or any such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or the Issuing Bank, irrespective of whether or not such Lender or the Issuing Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch or office of such Lender or the Issuing Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

(b) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (i) notify the Administrative Agent of such fact, and (ii) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

(x) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(y) the provisions of this paragraph shall not be construed to apply to (A) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Exposure to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this section shall apply).

The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Yield Protection

Section 5.01 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate) or the Issuing Bank;

(ii) subject any Lender or the Issuing Bank to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any LIBOR Loan made by it, or change the basis of taxation of payments to such Lender or the Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 5.02 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the Issuing Bank); or

(iii) impose on any Lender or the Issuing Bank or the London interbank market any other condition, cost or expense affecting this Agreement or LIBOR Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the Issuing Bank, the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate on an after-tax basis such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law affecting such Lender or the Issuing Bank or any lending office of such Lender or such Lender’s or the Issuing Bank’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional

Revolving Credit Agreement – Page 41

amount or amounts as will compensate on an after-tax basis such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in clause (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 5.02 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of clause (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability

Revolving Credit Agreement – Page 42

delivered to the Borrower by a Lender or the Issuing Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

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

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

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

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

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

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

(iv) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together

Revolving Credit Agreement – Page 43

with such supplementary documentation as may be prescribed by applicable law to permit the Borrower to determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If the Administrative Agent, a Lender or the Issuing Bank determines, in its sole judgment, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing Bank, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or the Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the Issuing Bank in the event the Administrative Agent, such Lender or the Issuing Bank is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent, any Lender or the Issuing Bank to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

Section 5.03 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 5.01, or requires the Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.02, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or 5.02, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.02, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.05(b)), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(i) the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 12.05(b)(iv);

Revolving Credit Agreement – Page 44

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Exposure, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.04) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.02, such assignment will result in a reduction in such compensation or payments thereafter; and

(iv) such assignment does not conflict with applicable law.

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

(c) Time Limited. Notwithstanding anything to the contrary contained in this Article V, the Borrower shall not be required to reimburse or pay any costs or expenses to any Lender as required by such sections which have accrued more than 180 days prior to such Lender’s giving notice to the Borrower that such Lender has suffered or incurred such costs or expenses.

(d) Non Discriminatory Basis. None of the Lenders shall be permitted to pass through to the Borrower costs and expenses under this Article V which are not also passed through by such Lender to other customers of such Lender similarly situated when such customer is subject to documents containing similar provisions as those contained in such Sections.

Section 5.04 Compensation. The Borrower shall pay to each Lender within 30 days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability which such Lender reasonably determines are attributable to:

(a) any payment, prepayment or conversion of a LIBOR Loan for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.02) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in Article V to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c); provided, however, that where such failure is attributable to the circumstances set forth in Sections 5.01(b), 5.02 or 5.03 with respect to such Lender’s inability or determination not to make LIBOR Loans, no such compensation shall be required. Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or

Revolving Credit Agreement – Page 45

conversion or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such borrowing) at the applicable rate of interest for such Loan provided for herein over (ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by such Lender).

Each request for a borrowing or issuance, renewal, extension or reissuance of a Letter of Credit by the Borrower hereunder shall constitute a certification by the Borrower to the effect set forth in Section 6.02(c) (both as of the date of such notice and, unless the Borrower otherwise notifies the Administrative Agent prior to the date of and immediately following such borrowing or issuance, renewal, extension or reissuance of a Letter of Credit as of the date thereof).

Section 6.03 Conditions Precedent for the Benefit of Lenders. All conditions precedent to the obligations of the Lenders to make any Loan are imposed hereby solely for the benefit of the Lenders, and no other Person may require satisfaction of any such condition precedent or be entitled to assume that the Lenders will refuse to make any Loan in the absence of strict compliance with such conditions precedent.

Section 6.04 Determinations Under Section 6.01. For purposes of determining compliance with the conditions specified in Section 6.01, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to the Lenders unless an officer of the Administrative Agent responsible for the transactions contemplated by the Loan Documents shall have received notice from such Lender with respect to any Loan or issuance of any Letters of Credit, prior to the Closing Date, specifying its objection thereto and such Lender shall not have made available to the Administrative Agent such Lender’s ratable portion of such Loan or issuance of any Letters of Credit.

Revolving Credit Agreement – Page 48

Section 7.01 Corporate Existence. Each of the Borrower and each Subsidiary: (i) is a corporation, limited partnership or limited liability company duly organized, legally existing and in good standing, if applicable, under the laws of the jurisdiction of its organization; (ii) (x) has all requisite power (corporate or otherwise), and (y) has all material governmental licenses, authorizations, consents and approvals necessary to own its assets and carry on its business as now being or as proposed to be conducted; and (iii) is qualified to do business in all jurisdictions in which the nature of the business conducted by it makes such qualification necessary, except in each case referred to in clauses (ii)(y) and (iii), to the extent the failure so to do could not reasonably be expected to have a Material Adverse Effect.

Section 7.02 Financial Condition. The audited consolidated balance sheet of Borrower as at December 31, 2005 and the related consolidated statement of income, stockholders’ equity and cash flow for the fiscal year ended on said date, with the opinion thereon of a Registered Public Accounting Firm heretofore furnished to each of the Lenders, are complete and correct and fairly present the consolidated financial condition of Borrower and its Consolidated Subsidiaries as at said dates and the results of its operations for the fiscal year, all in accordance with GAAP, as applied on a consistent basis. The unaudited consolidated balance sheet of the Borrower as at March 31, 2006 and the related consolidated statement of income, stockholders’ equity and cash flow for the portion of the fiscal year ended on such date are complete and correct and fairly present the consolidated financial condition of the Borrower and its Consolidated Subsidiaries as at said date, all in accordance with GAAP, as applied on a consistent basis (subject to normal year-end adjustments). Neither the Borrower nor any Subsidiary has on the Closing Date any material Debt, contingent liabilities, liabilities for taxes, forward or long-term commitments other than those customary in Borrower’s business or unrealized or anticipated losses from any unfavorable commitments, except as referred to or reflected or provided for in the Financial Statements or in Schedule 7.02. Since March 31, 2006, there has been no change or event that could reasonably be expected to have a Material Adverse Effect. Since the date of the Financial Statements, neither the Properties of the Borrower or any Subsidiary have been affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, permits or concessions by any Governmental Authority, riot, activities of armed forces or acts of God or of any public enemy where such event or matter could reasonably be expected to result in a Material Adverse Effect. Since the date of the Financial Statements, no Internal Control Event has occurred.

Section 7.03 Litigation. Except as disclosed to the Lenders in Schedule 7.03 hereto, at the Closing Date there is no litigation, legal, administrative or arbitral proceeding, investigation or other action of any nature pending or, to the knowledge of the Borrower threatened against or affecting the Borrower or any Subsidiary which can reasonably be expected to result in any judgment or liability against the Borrower or any Subsidiary not fully covered by insurance (except for normal deductibles) and which could reasonably be expected to have a Material Adverse Effect.

Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions hereof will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter or bylaws, partnership agreement, operating agreement or other organizational

Revolving Credit Agreement – Page 49

Such policies are sufficient for compliance with all requirements of law and of all agreements to which the Borrower or any Subsidiary is a party; are valid, outstanding and enforceable policies; provide adequate insurance coverage in at least such amounts and against at least such risks (but including in any event public liability) as are usually insured against in the same general area by companies engaged in the same or a similar business for the assets and operations of the Borrower and each Subsidiary; will remain in full force and effect through the respective dates set forth in Schedule 7.19 without the payment of additional premiums; and will not in any way be affected by, or terminate or lapse by reason of, the transactions contemplated by this Agreement.

take any action that, in its opinion or the opinion of its counsel, may expose such Agent to liability or that is contrary to any Loan Document or applicable law; and

No Agent shall be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.02 and 12.04) or (ii) in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until notice describing such Default is given to such Agent by the Borrower, a Lender or the Issuing Bank.

No Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent.

Section 11.04 Reliance by any Agent. Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the Issuing Bank, Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Bank unless such Agent shall have received notice to the contrary from such Lender or the Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 11.05 Delegation of Duties. Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by such Agent. Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and powers by or

Revolving Credit Agreement – Page 72

through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub agent and to the Related Parties of any Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an Agent.

Section 11.06 Resignation of an Agent. An Agent may at any time give notice of its resignation to the Lenders, the Issuing Bank and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States of America, or an Affiliate of any such bank with an office in the United States of America. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders and the Issuing Bank, appoint a successor Agent meeting the qualifications set forth above provided that if such Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Lenders or the Issuing Bank under any of the Loan Documents, the retiring Collateral Agent shall continue to hold such collateral security until such time as a successor Collateral Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through such Agent shall instead be made by or to each Lender and the Issuing Bank directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as such Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 12.03 shall continue in effect for the benefit of such retiring Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent.

Section 11.07 Non-Reliance on Agent and Other Lenders. Each Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 11.08 No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Bookrunners, Arrangers or Syndication Agent listed on the cover page hereof shall

Revolving Credit Agreement – Page 73

have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as an Agent, a Lender or the Issuing Bank hereunder.

Section 11.09 Issuing Bank as Agent. Administrative Agent hereby irrevocably appoints and authorizes the Issuing Bank to act as its agent (for the benefit of itself, the Administrative Agent and the other Lenders) under the Loan Documents with such other powers as are reasonably incidental thereto for purposes of holding maintaining, or taking any action with respect to the collateral securing the Obligations.

Section 11.10 Collateral and Guaranty Matters. The Lenders irrevocably authorize the Collateral Agent, at its option and in its discretion:

(a) to release any Lien on any Property granted to or held by the Collateral Agent under any Loan Document (i) upon termination of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit, (ii) that is sold or to be sold as part of or in connection with any sale permitted hereunder or under any other Loan Document, or (iii) subject to Section 12.04, if approved, authorized or ratified in writing by the Required Lenders; and

(b) to release any Guarantor from its obligations under the Guaranty Agreement if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

Upon request by the Collateral Agent at any time, the Required Lenders will confirm in writing the Collateral Agent’s authority to release its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty Agreement pursuant to this Section 11.10.

Section 11.11 Indemnification. Each of the Lenders, the Administrative Agent and the Issuing Bank (collectively, the “Lender Parties” and individually, a “Lender Party”) severally agrees to indemnify Administrative Agent (to the extent not promptly reimbursed by the Borrowers) from and against such Lender Party’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by such Agent under the Loan Documents (collectively, the “Indemnified Costs”); provided, however, that no Lender Party shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender Party agrees to reimburse Administrative Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, reasonable fees and expenses of counsel) payable by the Borrowers under Section 12.03, to the extent that such Agent is not promptly reimbursed for such costs and expenses by the Borrowers. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this

Revolving Credit Agreement – Page 74

Section 11.12 applies whether any such investigation, litigation or proceeding is brought by any Lender Party or any other Person.

ARTICLE XII

(iii) to indemnify and hold harmless from time to time the Indemnified Parties from and against any and all losses, claims, cost recovery actions, administrative orders or proceedings, damages and liabilities to which any such Person may become subject (i) under any Environmental Law applicable to the Borrower or any Subsidiary or any of their Properties, including without limitation, the treatment or disposal of hazardous substances on any of their Properties, (ii) as a result of the breach or non-compliance by the Borrower or any Subsidiary with any Environmental Law applicable to the Borrower or any Subsidiary, (iii) due to past ownership by the Borrower or any Subsidiary of any of their Properties or past activity on any of their Properties which, though lawful and fully permissible at the time, could result in present liability, (iv) the presence, use, release, storage, treatment or disposal of hazardous substances on or at any of the Properties owned or operated by the Borrower or any Subsidiary, or (v) any other environmental, health or safety condition in connection with the Loan Documents; provided, however, no indemnity or hold harmless protection shall be afforded under this Section 12.03(a)(iii) in respect of any Property for any occurrence arising from the acts or omissions of any Agent or any Lender during the period after which such Person, its successors or assigns shall have obtained possession of such Property (whether by foreclosure or deed in lieu of foreclosure, as mortgagee-in-possession or otherwise).

(b) No Indemnified Party may settle any claim to be indemnified without the consent of the indemnitor, such consent not to be unreasonably withheld; provided, that the indemnitor may not reasonably withhold consent to any settlement that an Indemnified Party proposes, if the indemnitor does not have the financial ability to pay all its obligations outstanding and asserted against the indemnitor at that time, including the maximum potential claims against the Indemnified Party to be indemnified pursuant to this Section 12.03.

(c) In the case of any indemnification hereunder, any Agent or Lender, as appropriate shall give notice to the Borrower of any such claim or demand being made against the Indemnified Party and the Borrower shall have the non-exclusive right to join in the defense against any such claim or demand provided that if the Borrower provides a defense, the Indemnified Party shall bear its own cost of defense unless there is a conflict between the Borrower and such Indemnified Party.

(d) Except as expressly provided in the proviso to Section 12.03(a)(iii) above, the foregoing indemnities shall extend to the Indemnified Parties notwithstanding the sole or concurrent negligence of every kind or character whatsoever, whether active or passive, whether an affirmative act or an omission, including without limitation, all types of negligent conduct identified in the restatement (second) of torts of one or more of the Indemnified Parties or by reason of strict liability imposed without fault on any one or more of the Indemnified Parties. To the extent that an Indemnified Party is found to have committed an act of gross negligence or willful misconduct, this contractual obligation of indemnification shall continue but shall only

Revolving Credit Agreement – Page 78

extend to the portion of the claim that is deemed to have occurred by reason of events other than the gross negligence or willful misconduct of the Indemnified Party.

(e) The Borrower’s obligations under this Section 12.03 shall survive any termination of this Agreement and the payment of the Obligations and shall continue thereafter in full force and effect.

Section 12.05 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of clause (b) of this Section, (ii) by way of participation in accordance with the provisions of clause (d) of this Section or (iii) by way of 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 party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in clause (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption substantially in the form of Exhibit F attached hereto (the “Assignment”) with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment, as of the Trade Date) shall not be less than $3,000,000, in the case of any assignment in respect of a revolving facility, or $1,000,000, in the case of any assignment in respect of a term facility, unless each of the Administrative Agent and, so long as no Default has occurred and is continuing, the Borrower otherwise consent (each such consent not to be unreasonably withheld or delayed); provided however, that simultaneous assignments to related Funds or by related Approved Funds shall be treated as one assignment for purposes of determining whether the minimum assignment amount has been satisfied hereunder;

Revolving Credit Agreement – Page 80

(ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Tranches on a non-pro rata basis;

(iii) any assignment of a Commitment must be approved by the Administrative Agent and the Issuing Bank unless the Person that is the proposed assignee is itself a Lender with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire, provided that only one such fee shall be payable in connection with simultaneous assignments to two or more related Funds or by two or more related Approved Funds.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause (c) of this Section, from and after the effective date specified in each Assignment, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment, be released from its obligations under this Agreement (and, in the case of an Assignment covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Article V and Section 12.03 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with clause (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at its office in Detroit, Michigan a copy of each Assignment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries ) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall

Revolving Credit Agreement – Page 81

remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the Lenders and Issuing Bank shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to the following: extending the final maturity of the Loans, forgives the principal amount of any Loans outstanding under this Agreement, releases any guarantor of the Obligations or releases all or substantially all of the collateral, or reduces the interest rate applicable to the Loans or the fees payable to the Lenders generally, described in Section 12.04(i) that affects such Participant. Subject to clause (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Article V to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to clause (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.13 as though it were a Lender, provided such Participant agrees to be subject to Section 4.05 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 5.01 and 5.02 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.02 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.02(e) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement 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 pledgee or assignee for such Lender as a party hereto.

(g) Dissenting Lenders. In the event that the Borrower shall request that the Lender Parties enter into any amendment, modification, consent or waiver with respect to this Agreement or any other Loan Document, and any Lender Party elects not to enter into such amendment, modification, consent or waiver (each such Lender Party being a “Dissenting Lender”), then the Borrower shall have the right upon 10 days’ written notice to the Administrative Agent and such Dissenting Lender, to require (so long as the Administrative Agent consents thereto) each such Dissenting Lender to assign 100% of the rights and obligations of the Dissenting Lender at par to any Lender Party or any other financial institution which satisfies the requirements of Section 12.05(b) and has been consented to by the Administrative Agent so long as (i) the Required Lenders have otherwise approved such amendment, modification, consent or waiver and (ii) such assignee described above approves such amendment, modification, consent or waiver. Each such assignment shall be made pursuant

Revolving Credit Agreement – Page 82

to an Assignment and shall comply with the other terms of this Section 12.05. The Borrower shall pay, and/or cause such relevant assignee to pay, to such Dissenting Lender, concurrently with the effectiveness of each such assignment, any amounts payable under this Agreement that would have been payable if the Borrower had voluntarily prepaid such Loans. The Dissenting Lender shall not be required to pay any fee relating to such assignment.

Section 12.06 Invalidity. In the event that any one or more of the provisions contained in any of the Loan Documents or the Letters of Credit, or the Letter of Credit Agreements shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement or any other Loan Document.

Section 12.07 Counterparts, etc.

(a) Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

(b) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

Section 12.08 Survival. The obligations of the parties under Article V, and Section 12.03 shall survive the repayment of the Loans and the termination of the Commitments. To the extent that any payments on the Obligations or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each other Loan Document effective immediately prior thereto shall continue in full force and effect. In such event, each such Loan Document shall be automatically reinstated and the

Revolving Credit Agreement – Page 83

Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

Section 12.09 Captions. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement.

Section 12.10 Governing Law; Submission to Jurisdiction.

(a) Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Michigan.

(b) Submission to Jurisdiction. The Borrower irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the courts of the State of Michigan or Federal Court of the United States of America sitting in the Eastern District of Michigan, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Michigan State court or, to the fullest extent permitted by applicable law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document shall affect any right that any Agent, any Lender or the Issuing Bank may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

(c) Waiver of Venue. The Borrower irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in clause (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Service of Process. Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 12.02. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by applicable law.

Section 12.11 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and,

Revolving Credit Agreement – Page 84

to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 12.11 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Lender.

Section 12.12 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO RELATED PARTY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 12.13 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender, the Issuing Bank, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Issuing Bank or any such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or the Issuing Bank, irrespective of whether or not such Lender or the Issuing Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch or office of such Lender or the Issuing Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

Section 12.14 Confidentiality.

(a) The Administrative Agent, the Lenders and the Issuing Bank agree to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of

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

Section 12.15 Exculpation Provisions. Each of the parties hereto specifically agrees that it has a duty to read this Agreement and the other Loan Documents and agrees that it is charged with notice and knowledge of the terms of this Agreement and the other Loan Documents; that it has in fact read this Agreement and is fully informed and has full notice and knowledge of the terms, conditions and effects of this Agreement; that it has been represented by independent legal counsel of its choice throughout the negotiations preceding its execution of this Agreement and the other Loan Documents; and has received the advice of its attorney in entering into this Agreement and the other Loan Documents; and that it recognizes that certain of the terms of this Agreement and the other Loan Documents result in one party assuming the liability inherent in some aspects of the transaction and relieving the other party of its responsibility for such liability. Each party hereto agrees and covenants that it will not contest the validity or

Revolving Credit Agreement – Page 86

enforceability of any exculpatory provision of this Agreement and the other Loan Documents on the basis that the party had no notice or knowledge of such provision or that the provision is not “conspicuous.”

Section 12.16 USA Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.
