The Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 10:00 a.m. (Chicago time) one Business Day prior to the Borrowing Date of each Floating Rate Advance (except that if the Borrowing Date is a Settlement Date, the Borrower may give such Borrowing Notice on such date) and three Business Days before the Borrowing Date for each Eurodollar Advance, specifying (in the form of Exhibit A for Eurodollar Advances): (1) the Borrowing Date, which shall be a Business Day, of such Advance, (2) the aggregate amount of such Advance, (3) the Type of Advance selected; provided that, if such Borrower fails to specify the Type of Advance requested, such request shall be deemed a request for a Floating Rate Advance; and (4) the duration of the Interest Period if the Type of Advance requested is a Eurodollar Advance; provided that, if such Borrower fails to select the duration of the Interest Period for the requested Eurodollar Advance, such Borrower shall be deemed to have requested that such Eurodollar Advance be made with an Interest Period of one month.

(c) The Agent’s Election. Promptly after receipt of a Borrowing Notice (or telephonic notice in lieu thereof) of a requested Floating Rate Advance, the Agent shall elect in its discretion to have the terms of Section 2.1.1(d) (pro rata advance by all Lenders) or Section 2.1.4 (advance by the Agent, in the form of a Non-Ratable Loan, on behalf of the Lenders) apply to such requested Advance.

(d) Pro Rata Advance. Unless the Agent elects to have the terms of Section 2.1.4 apply to a requested Floating Rate Advance or if a requested Advance is for a Eurodollar Advance, then promptly after receipt of a Borrowing Notice or telephonic notice in lieu thereof as permitted by Section 2.8, the Agent shall notify the Lenders by telecopy, telephone, or e-mail of the requested Advance. Not later than noon (Chicago time) on each Borrowing Date, each Lender shall make available its Revolving Loan in funds immediately available in Chicago to the Agent and the Agent will make the funds so received from the Lenders available to the Borrower at the Borrower’s Funding Account as set forth in Section 2.5.

2.1.2. Facility LCs.

(a) Issuance. The LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby and commercial Letters of Credit (each, a “Facility LC”) and to renew, extend, increase, decrease or otherwise modify each Facility LC

(“Modify,” and each such action a “Modification”), from time to time from and including the Effective Date and prior to the Facility Termination Date upon the request and for the account of the Borrower; provided that, the maximum face amount of the Facility LC to be issued or Modified, does not exceed the lesser of (i) an amount equal to $20,000,000 minus the sum of (1) the aggregate undrawn amount of all outstanding Facility LCs at such time plus, without duplication, (2) the aggregate unpaid Reimbursement Obligations with respect to all Facility LCs outstanding at such time and (ii) Availability. No Facility LC shall have an expiry date later than the earlier of (x) the thirtieth (30th) Business Day prior to the Facility Termination Date and (y) one year after its issuance; provided that any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (x) above).

(b) Participations. Upon the issuance or Modification by the LC Issuer of a Facility LC in accordance with this Section 2.1.2, the LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share.

(c) Notice. Subject to Section 2.1.2(a), the Borrower shall give the LC Issuer notice prior to 10:00 a.m. (Chicago time) at least three Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the LC Issuer shall promptly notify the Agent, and the Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification by the LC Issuer of any Facility LC shall, in addition to the conditions precedent set forth in Article IV (the satisfaction of which the LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be satisfactory to the LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as the LC Issuer shall have reasonably requested (each, a “Facility LC Application”). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

(d) Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the LC Issuer shall notify the Agent and the Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of the LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. The LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the LC Issuer, each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Default or any condition precedent whatsoever, to reimburse the LC Issuer on demand for (i) such Lender’s Pro Rata Share of the amount of each payment made by the LC Issuer under each Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.1.2(e) below, plus (ii) interest on the foregoing amount to be

reimbursed by such Lender, for each day from the date of the LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 a.m. (Chicago time) on such date, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Floating Rate Advances.

(e) Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amounts to be paid by the LC Issuer (i) immediately upon any drawing under any Facility LC by Borrower automatically (and without any notice required to Agent) requesting a Revolving Loan so long as the conditions set forth in Section 4.2 are satisfied or (ii) within one Business Day of any drawing under any Facility LC, in each case, without presentment, demand, protest or other formalities of any kind; provided that, neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii) the LC Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to Floating Rate Advances for such day if such day falls on or before the applicable LC Payment Date and (y) the sum of 2% plus the rate applicable to Floating Rate Advances for such day if such day falls after such LC Payment Date. The LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer, but only to the extent such Lender has made payment to the LC Issuer in respect of such Facility LC pursuant to Section 2.1.2(d). Subject to the terms and conditions of this Agreement (including without limitation the submission of a Borrowing Notice in compliance with Section 2.1.1(b) and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

(f) Obligations Absolute. The Borrower’s obligations under this Section 2.1.2 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and the Lenders that the LC Issuer and the Lenders shall not be responsible for, and the Borrower’s Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. The LC Issuer shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by the LC Issuer or any Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the LC Issuer or any Lender under any liability

to the Borrower. Nothing in this Section 2.1.2(f) is intended to limit the right of the Borrower to make a claim against the LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.1.2(e).

(g) Actions of LC Issuer. The LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the LC Issuer. The LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.1.2, the LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC.

(h) Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and the Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the LC Issuer or the Agent may incur (or which may be claimed against such Lender, the LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the LC Issuer hereunder (but nothing herein contained shall affect any rights the Borrower may have against any Defaulting Lender) or (ii) or on account of the LC Issuer issuing any Facility LC which specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, evidencing the appointment of such successor Beneficiary; provided that, the Borrower shall not be required to indemnify any Lender, the LC Issuer or the Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.1.2(h) is intended to limit the obligations of the Borrower under any other provision of this Agreement.

(i) Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuer, its Affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such

indemnitees may suffer or incur in connection with this Section 2.1.2 or any action taken or omitted by such indemnitees hereunder.

(j) Facility LC Collateral Account. The Borrower agrees that it will, upon the request of the Agent or the Required Lenders (which request shall be made with respect to a Facility LC constituting a standby letter of credit only during the continuance of a Default or an Unmatured Default) and until the final expiration date of any Facility LC and thereafter as long as any amount is payable to the LC Issuer or the Lenders in respect of any Facility LC, maintain a special collateral account pursuant to arrangements satisfactory to the Agent (the “Facility LC Collateral Account”) at the Agent’s office at the address specified pursuant to Article XIII, in the name of the Borrower but under the sole dominion and control of the Agent, for the benefit of the Lenders and in which the Borrower shall have no interest other than as set forth in Section 8.1. Nothing in this Section 2.1.2(j) shall either obligate the Agent to require the Borrower to deposit any funds in the Facility LC Collateral Account or limit the right of the Agent to release any funds held in the Facility LC Collateral Account in each case other than as required by Section 8.1. The Borrower hereby grants to the Agent, on behalf of and for the ratable benefit of the Lenders and the LC Issuer, a security interest in all of the Borrower’s right, title and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and complete payment and performance of the Secured Obligations. The Agent will invest any funds on deposit from time to time in the Facility LC Collateral Account in certificates of deposit of JPMorgan Chase Bank, N.A. having a maturity not exceeding thirty days.

(k) Rights as a Lender. In its capacity as a Lender, the LC Issuer shall have the same rights and obligations as any other Lender.

(l) Termination of the Facility. If, notwithstanding the provisions of this Section 2.1.2, any Facility LC is outstanding upon the earlier of (x) the termination of this Agreement and (y) the Facility Termination Date, then upon such termination the Borrower shall deposit with the Agent, for the benefit of the Agent and the Lenders, with respect to all LC Obligations, as the Agent in its discretion shall specify, either (i) a standby letter of credit (a “Supporting Letter of Credit”), in form and substance satisfactory to the Agent, issued by an issuer satisfactory to the Agent, in a stated amount, equal to 105% of the difference of (x) the amount of LC Obligations at such time, less (y) the amount on deposit in the Facility LC Collateral Account at such time which is free and clear of all rights and claims of third parties and has not been applied against the Obligations (such difference, the “Collateral Shortfall Amount”), under which Supporting Letter of Credit the Agent is entitled to draw amounts necessary to reimburse the Agent, the LC Issuer and the Lenders for payments to be made by the Agent, the LC Issuer and the Lenders under any such Facility LC and any fees and expenses associated with such Facility LC, or (ii) cash, in immediately available funds, in an amount equal to 105% of the Collateral Shortfall Amount to be held in the Facility LC Collateral Account. Such Supporting Letter of Credit or deposit of cash shall be held by the Agent, for the benefit of the Agent and the Lenders, as security for, and to provide for the payment of, the aggregate undrawn amount of such Facility LC remaining outstanding.

2.1.3. Swingline Loans.

(a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower, from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $20,000,000 or (ii) the sum of the total Credit Exposures exceeding the lesser of the total Commitments and

Availability; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan and provided further, however, that each Swingline Loan shall be in an amount that is an integral multiple of $1,000,000 and not less than $1,000,000. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans. To request a Swingline Loan, the Borrower shall notify the Agent of such request by telephone (confirmed by facsimile), not later than noon, Chicago time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit to the Funding Account(s) (or, in the case of a Swingline Loan made to finance the reimbursement of amounts paid by the LC Issuer upon any drawing under any Facility LC as provided in Section 2.1.1(e), by remittance to the LC Issuer, and in the case of repayment of another Loan or fees or expenses as provided by Sections 2.1.4, 2.1.5 or 2.18(b), by remittance to the Agent to be distributed to the Lenders) by 2:00 p.m., Chicago time, on the requested date of such Swingline Loan. In addition, the Borrower hereby authorizes the Swingline Lender to, and the Swingline Lender shall, subject to the terms and conditions set forth herein (but without any further written notice required), not later than 1:00 p.m., Chicago time, on each Business Day, make available to the Borrower by means of a credit to the Funding Account(s), the proceeds of a Swingline Loan to the extent necessary to pay items to be drawn on any Collateral Deposit Account (as such term is defined in the Security Agreement) that day (as determined based on notice from the Agent).

(b) The Swingline Lender may by written notice given to the Agent not later than 11:00 a.m., Chicago time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which the Lenders will participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Pro Rata Share of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Agent, for the account of the Swingline Lender, such Lender’s Pro Rata Share of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of an Unmatured Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.1.1(d) with respect to Loans made by such Lender (and Section 2.1.1(d) shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Agent; any such amounts received by the Agent shall be promptly remitted by the Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a

Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

(c) The Agent, the Swingline Lender and the Lenders agree that in order to facilitate the administration of this Agreement and the other Loan Documents, promptly after the Borrower requests a Floating Rate Advance, the Swingline Lender may elect to have the terms of this Section 2.1.3(c) apply to such Borrowing Notice by advancing, on behalf of the Lenders and in the amount requested, same day funds to the Borrower, on the applicable Borrowing Date to the Funding Account(s) (each such Loan made solely by the Swingline Lender pursuant to this Section 2.1.3(c) is referred to in this Agreement as a “Swingline Loan”), with settlement among them as to the Swingline Loans to take place on a periodic basis as set forth in Section 2.1.3(e). Each Swingline Loan shall be subject to all the terms and conditions applicable to other Floating Rate Advances funded by the Lenders, except that all payments thereon shall be payable to the Swingline Lender solely for its own account. In addition, the Borrower hereby authorizes the Swingline Lender to, and the Swingline Lender shall, subject to the terms and conditions set forth herein (but without any further written notice required), not later than 1:00 p.m., Chicago time, on each Business Day, make available to the Borrower by means of a credit to the Funding Account(s), the proceeds of a Swingline Loan to the extent necessary to pay items to be drawn on any Collateral Deposit Account (as such term is defined in the Security Agreement) that day (as determined based on notice from the Agent). The aggregate amount of Swingline Loans outstanding at any time shall not exceed $20,000,000. The Swingline Lender shall not make any Swingline Loan if the requested Swingline Loan exceeds Availability (before giving effect to such Swingline Loan). All Swingline Loans shall be Floating Rate Advances.

(d) Upon the making of a Swingline Loan (whether before or after the occurrence of an Unmatured Default and regardless of whether a Settlement has been requested with respect to such Swingline Loan), each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Swingline Lender without recourse or warranty, an undivided interest and participation in such Swingline Loan in proportion to its Pro Rata Share of the Commitment. The Swingline Lender may, at any time, require the Lenders to fund their participations. From and after the date, if any, on which any Lender is required to fund its participation in any Swingline Loan purchased hereunder, the Agent shall promptly distribute to such Lender, such Lender’s Pro Rata Share of all payments of principal and interest and all proceeds of Collateral received by the Agent in respect of such Loan.

(e) The Agent, on behalf of the Swingline Lender, shall request settlement (a “Settlement”) with the Lenders on at least a weekly basis or on any date that the Agent elects, by notifying the Lenders of such requested Settlement by facsimile, telephone, or e-mail no later than 12:00 noon Chicago time on the date of such requested Settlement (the “Settlement Date”). Each Lender (other than the Swingline Lender, in the case of the Swingline Loans) shall transfer the amount of such Lender’s Pro Rata Share of the outstanding principal amount of the applicable Loan with respect to which Settlement is requested to the Agent, to such account of the Agent as the Agent may designate, not later than 2:00 p.m., Chicago time, on such Settlement Date. Settlements may occur during the existence of an Unmatured Default and whether or not the applicable conditions precedent set forth in Section 4.02 have then been satisfied. Such amounts transferred to the Agent shall be applied against the amounts of the Swingline Lender’s Swingline Loans and, together with Swingline Lender’s Pro Rata Share of such Swingline Loan, shall constitute Revolving Loans of such Lenders, respectively. If any such amount is not transferred to the Agent by any Lender on such Settlement Date, the Swingline Lender shall be entitled to

recover such amount on demand from such Lender together with interest thereon as specified in Section 2.24.

2.1.4. Non-Ratable Loans. Subject to the restrictions set forth in Section 2.1.1(a), the Agent may elect to have the terms of this Section 2.1.4 apply to any requested Floating Rate Advance and JPMorgan Chase Bank, N.A. shall thereafter make an Advance, on behalf of the Lenders and in the amount requested, available to the Borrower on the applicable Borrowing Date by transferring same day funds to the Funding Account. Each Advance made solely by the Agent pursuant to this Section 2.1.4 is referred to in this Agreement as a “Non-Ratable Loan,” and such Advances are referred to as the “Non-Ratable Loans.” Each Non-Ratable Loan shall be subject to all the terms and conditions applicable to other Advances funded by the Lenders, except that all payments thereon shall be payable to JPMorgan Chase Bank, N.A. solely for its own account. The Agent shall not make any Non-Ratable Loan if the requested Non-Ratable Loan exceeds Availability (before giving effect to such Non-Ratable Loan). Non-Ratable Loans may be made even if a Default or Unmatured Default exists, but may not be made if the other conditions precedent set forth in Section 4.2 have not been satisfied. The Non-Ratable Loans shall be secured by the Liens granted to the Agent in and to the Collateral and shall constitute Obligations hereunder. All Non-Ratable Loans shall be Floating Rate Advances and are subject to the settlement provisions set forth in Section 2.20.

2.1.5. Protective Advances. Subject to the limitations set forth below, the Agent is authorized by the Borrower and the Lenders, from time to time in the Agent’s sole discretion (but shall have absolutely no obligation to) during the continuation of a Unmatured Default or Default, to make Advances to the Borrower, on behalf of all Lenders, in an aggregate amount outstanding at any time not to exceed 10% of the Borrowing Base, which the Agent, in its Permitted Discretion, deems necessary or desirable (i) to preserve or protect the Collateral, or any portion thereof, (ii) to enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations, or (iii) to pay any other amount chargeable to or required to be paid by the Borrower pursuant to the terms of this Agreement, including costs, fees, and expenses as described in Section 9.6 (any of such Advances are herein referred to as “Protective Advances”); provided that, no Protective Advance shall cause the Aggregate Credit Exposure to exceed the Aggregate Commitment. Protective Advances may be made even if the conditions precedent set forth in Section 4.2 have not been satisfied. The Protective Advances shall be secured by the Liens in favor of the Agent in and to the Collateral and shall constitute Obligations hereunder. All Protective Advances shall be Floating Rate Advances, shall bear interest at the default rate set forth in Section 2.12 and shall be payable on the earlier of demand or the Facility Termination Date. The Required Lenders may at any time revoke the Agent’s authorization to make Protective Advances. Any such revocation must be in writing and shall become effective prospectively upon the Agent’s receipt thereof. At any time that there is sufficient Availability and the conditions precedent set forth in Section 4.2 have been satisfied, the Agent may request the Lenders to make a Revolving Loan to repay a Protective Advance. At any other time the Agent may require the Lenders to fund their risk participations described in Section 2.2. Agent shall notify the Lenders of the making of any Protective Advance within two Business Days thereafter and will endeavor to give the Lenders notice in advance of making any Protective Advance when practical.

2.1.6. Reallocation of Loans and Commitments. On the Closing Date, (i) each Lender, if any, whose relative proportion of its Commitment hereunder is increasing over the proportion of the Commitment held by it prior to the Closing Date under the Original Agreement shall, by assignments among them (which assignments shall be deemed to occur hereunder automatically, and without any requirement for additional documentation, on the Closing Date) acquire a portion of the Loans and Commitments held by them from and among each other and (ii) each Lender who is becoming a party hereto on the Closing Date shall acquire a portion of the Loans and Commitments which increased from the Original Agreement. Pursuant to the foregoing sentence, the Lenders, shall, through the Agent, make such other adjustments among themselves as shall be necessary so that after giving effect to assignments and adjustments, the Lenders shall hold all Loans outstanding under this Agreement ratably in accordance with their respective Commitments as reflected on the Commitment Schedule, as modified from time to time pursuant to the terms hereof.

2.2. Ratable Loans; Risk Participation. Except as otherwise provided below, each Advance made in connection with a Revolving Loan shall consist of Loans made by each Lender in an amount equal to such Lender’s Pro Rata Share. Each Advance made in connection with a Swingline Loan shall consist of Loans made by the Lenders as provided in Section 2.1.3. Upon the making of an Advance by the Agent in connection with a Non-Ratable Loan (whether before or after the occurrence of a Default or an Unmatured Default and regardless of whether the Agent has requested a Settlement with respect to such Non-Ratable Loan), the Agent shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Agent, without recourse or warranty, an undivided interest and participation in such Non-Ratable Loan in proportion to its Pro Rata Share of the Commitment. Upon the making of an Advance by the Agent in connection with a Protective Advance (whether before or after the occurrence of a Default or an Unmatured Default and regardless of whether the Agent has requested a Settlement with respect to such Protective Advance), the Agent shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Agent, without recourse or warranty, an undivided interest and participation in such Protective Advance in proportion to its Pro Rata Share of the Aggregate Commitment. From and after the date, if any, on which any Lender is required to fund its participation in any Swingline Loan, Non-Ratable Loan, or Protective Advance purchased hereunder, the Agent shall promptly distribute to such Lender, such Lender’s Pro Rata Share of all payments of principal and interest and all proceeds of Collateral received by the Agent in respect of such Loan.

2.3. Payment of the Obligations. The Borrower shall repay the outstanding principal balance of the Loans, together with all other Obligations, including all accrued and unpaid interest thereon, on the Facility Termination Date; provided, however, that the Borrower shall repay the unpaid principal amount of each Swingline Loan to the Swingline Lender (or Agent, as provided in Section 2.1.3(b)) on the earlier of the Facility Termination Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least two Business Days after such Swingline Loan is made; provided further, however, that on each date that a Revolving Loan is made, the Borrower shall repay all Swingline Loans then outstanding.

2.4. Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $1,000,000 and in multiples of $100,000 if in excess thereof. Floating Rate Advances may be in any amount.

2.5. Funding Account. The Borrower shall deliver to the Agent, on the Effective Date, a notice setting forth the deposit account of the Borrower (the “Funding Account”) to which the Agent is authorized by the Borrower to transfer the proceeds of any Advances requested pursuant to this Agreement. The Borrower may designate a replacement Funding Account from time to time by written notice executed by an Authorized Officer delivered to the Agent. Any designation by the Borrower of the Funding Account must be reasonably acceptable to the Agent.

2.6. Reliance Upon Authority; No Liability. The Agent is entitled to rely conclusively on any Authorized Individual’s request for Advances hereunder, so long as the proceeds thereof are to be transferred to the Funding Account. The Agent shall have no duty to verify the identity of any individual representing himself or herself as an Authorized Individual authorized by the Borrower to make such requests on its behalf. The Agent shall not incur any liability to the Borrower as a result of acting upon any notice referred to in Section 2.1 which the Agent reasonably believes to have been given by an Authorized Individual. The crediting of Advances to the Funding Account shall conclusively establish the obligation of the Borrower to repay such Advances as provided herein.

2.7. Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into

Eurodollar Advances pursuant to this Section 2.7 or are repaid in accordance with this Agreement. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with this Agreement or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.4, the Borrower may elect from time to time to convert all or any part of a Floating Rate Advance into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice in the form of Exhibit B (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least three Business Days prior to the date of the requested conversion or continuation, specifying (i) the requested date, which shall be a Business Day, of such conversion or continuation, (ii) the aggregate amount and Type of the Advance which is to be converted or continued, and (iii) the amount of such Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto. This Section 2.7 shall not apply to Swingline Loans, which may not be converted or continued.

2.8. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the Agent or any Lender, of each telephonic notice signed by an Authorized Individual. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.9. Notification of Advances, Interest Rates and Repayments. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. Promptly after notice from the LC Issuer, the Agent will notify each Lender of the contents of each request for issuance of a Facility LC hereunder or any Modification. The Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

2.10. Fees.

(a) Unused Commitment Fee. The Borrower agrees to pay to the Agent, for the account of each Lender in accordance with such Lender’s Pro Rata Share, an unused commitment fee at a per annum rate equal to the Applicable Fee Rate on the average daily Available Commitment, payable on each Payment Date hereafter and on the Facility Termination Date (the “Unused Commitment Fee”); provided, however, that the Unused Commitment Fee shall not accrue on a portion of the Available Commitment equal to 5% of the Aggregate Credit Exposure during any period that the Loan Parties are prohibited from making purchases of Compression Units or Heavy Component Inventory pursuant to Section 6.28.

(b) LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in effect from time to time on the average daily undrawn stated amount under each Facility LC, such fee to be payable in arrears on each Payment Date (the “LC Fee”). The Borrower shall also pay to the LC Issuer for its own account documentary and processing charges in connection with the

issuance or Modification of and draws under Facility LCs in accordance with the LC Issuer’s standard schedule for such charges as in effect from time to time.

(c) Agent and Arranger Fees. The Borrower agrees to pay to the Agent and the Arranger, such additional fees as are specified in the Amended and Restated Commitment Fee Letter dated as of the Closing Date between Riverstone Holdings and the Agent (the “Commitment Fee Letter”) and the Ticking Fee Letter dated as of the Closing Date between Riverstone Holdings and the Agent (the “Ticking Fee Letter”, together with the Commitment Fee Letter, the “Fee Letter”). The closing fee payable pursuant to the Fee Letter shall be paid to Agent as set forth herein, for the account of each Lender in accordance with such Lender’s Pro Rata Share. All other fees payable pursuant to the Fee Letter shall be payable to the Agent or Arranger, as applicable, for their own account.

2.11. Interest Rates. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.7, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.7 hereof, at a rate per annum equal to the Floating Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower’s selections under Sections 2.1.1 and 2.7 and otherwise in accordance with the terms hereof. No Interest Period may end after the Facility Termination Date. If at any time Loans are outstanding with respect to which the Borrower has not delivered a notice to the Agent specifying the basis for determining the interest rate applicable thereto, those Loans shall bear interest at the Floating Rate.

2.12. Eurodollar Advances Post Default; Default Rates. Notwithstanding anything to the contrary contained hereunder, during the continuance of a Default or Unmatured Default the Agent or the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.3 requiring unanimous consent of the Lenders to reductions in interest rates), declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Agent or the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.3 requiring unanimous consent of the Lenders to reductions in interest rates), declare that (i) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus 2% per annum, (ii) each Floating Rate Advance shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum and (iii) the LC Fee shall be increased by 2% per annum, provided that, during the continuance of a Default under subsection (f) or (g) of Article VII, the interest rates set forth in clauses (i) and (ii) above and the increase in the LC Fee set forth in clause (iii) above shall be applicable to all Credit Extensions without any election or action on the part of the Agent or any Lender.

2.13. Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest on all Advances, unused commitment fees and LC Fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on all Floating Rate Advances shall be calculated for actual days elapsed on the basis of 365 or 366 day year, as appropriate. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon

(local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. After giving effect to any Loan, Advance, continuation, or conversion of any Eurodollar Borrowing, there may not be more than six (6) different Interest Periods in effect at the same time hereunder.

2.14. Voluntary Prepayments. The Borrower may from time to time prepay, without penalty or premium, all or any portion of the outstanding Floating Rate Advances. The Borrower may also from time to time prepay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $500,000 in excess thereof, any portion of the outstanding Eurodollar Advances upon five Business Days’ prior notice to the Agent.

2.15. Mandatory Prepayments.

(a) Borrowing Base Compliance. The Borrower shall immediately repay the Revolving Loans, Swingline Loans, Reimbursement Obligations and/or Non-Ratable Loans if at any time the Aggregate Credit Exposure exceeds the lesser of (i) the Commitment and (B) the Borrowing Base, to the extent required to eliminate such excess. If any such excess remains after repayment in full of all outstanding Revolving Loans, Swingline Loans, Reimbursement Obligations and Non-Ratable Loans, the Borrower shall provide cash collateral or a Supporting Letter of Credit for the LC Obligations in the manner set forth in Section 2.1.2(l) to the extent required to eliminate such excess.

(b) Sale of Assets. Immediately upon receipt by any Loan Party of the Net Cash Proceeds of any asset disposition (other than sales of Inventory in the ordinary course of business), the Borrower shall prepay the Obligations in an amount equal to all such Net Cash Proceeds. Any such prepayment shall be applied first, to pay the principal of the Protective Advances, second, to pay the principal of the Non-Ratable Loans, third, to pay the principal of the Revolving Loans and Swingline Loans without a concomitant reduction in the Commitment, and fourth, to cash collateralize outstanding Facility LCs.

(c) Issuance of Debt or Equity. If Borrower issues Capital Stock (other than issuance from the Incentive Pool to a Special Limited Partner, as each such term is defined in the Borrower’s Partnership Agreement) or any Loan Party issues Indebtedness (other than Indebtedness permitted by Sections 6.17 or if any Loan Party receives any dividend or distribution from a Person other than a Loan Party, no later than the Business Day following the date of receipt of any Net Cash Proceeds of such issuance or receipt of such dividend, distribution, loan or advance, the Borrower shall prepay the Obligations in an amount equal to all such Net Cash Proceeds, dividends, distributions, loans or advances. Any such prepayment shall be applied first, to pay the principal of the Protective Advances, second, to pay the principal of the Non-Ratable Loans, third, to pay the principal of the Revolving Loans and Swingline Loans without a concomitant reduction in the Commitment, and fourth, to cash collateralize outstanding Facility LCs.

(d) Insurance/Condemnation Proceeds. Any insurance or condemnation proceeds to be applied to the Obligations in accordance with Section 6.7(c) shall be applied as follows: (i) insurance proceeds from casualties or losses to cash or Inventory shall be applied, first, to the Protective Advances, second, to the Non-Ratable Loans, third, to the Revolving Loans and Swingline Loans, and fourth, to cash collateralize outstanding Facility LCs; and (ii) insurance or condemnation proceeds from casualties or losses to Equipment, Fixtures and real Property shall be applied first, to pay the principal of the Protective

Advances, second, to pay the principal of the Non-Ratable Loans, third, to pay the principal of the Revolving Loans and Swingline Loans, and fourth, to cash collateralize outstanding Facility LCs. The Commitment shall not be permanently reduced by the amount of any such prepayments. If the precise amount of insurance or condemnation proceeds allocable to Inventory as compared to Equipment, Fixtures and real Property is not otherwise determined, the allocation and application of those proceeds shall be determined by the Agent, in its Permitted Discretion.

(e) General. Without in any way limiting the foregoing, promptly upon receipt by any Loan Party of proceeds of any sale of any Collateral, the Borrower shall cause such Loan Party to deliver such proceeds to the Agent, or deposit such proceeds in a deposit account subject to a Deposit Account Control Agreement. All of such proceeds shall be applied as set forth above or otherwise as provided in Section 2.19. Nothing in this Section 2.15 shall be construed to constitute Agent’s or any Lender’s consent to any transaction that is not permitted by other provisions of this Agreement or the other Loan Documents. Nothing in this Section 2.15 shall be construed to constitute a permanent reduction in the Aggregate Commitment or to prejudice the Borrower’s rights under Section 2.1.1(a)(i), subject to the terms of this Agreement, to borrower, repay and reborrow Revolving Loans at any time prior to the Facility Termination Date.

2.16. Borrower’s Reduction of Commitment. Prior to the Facility Termination Date, Borrower may, upon five (5) Business Days’ prior written notice to Agent, permanently reduce (but not terminate) the Aggregate Commitment to a lesser amount, provided that such reduction must be $5,000,000 or a higher integral multiple of $1,000,000 and the aggregate amount of such reductions may not exceed $15,000,000.

2.17. Termination of the Facility.

(a) Without limiting Section 2.3 or Section 8.1, (a) the Aggregate Commitments shall expire on the Facility Termination Date and (b) the Aggregate Credit Exposure and all other unpaid Obligations shall be paid in full by the Borrower on the Facility Termination Date.

(b) The Borrower may terminate this Agreement upon at least 10 Business Days’ prior written notice thereof to the Agent and the Lenders, upon (i) the payment in full of all outstanding Loans, together with accrued and unpaid interest thereon, (ii) the cancellation and return of all outstanding Facility LCs (or alternatively, with respect to each such Facility LC, the furnishing to the Agent of a cash deposit or Supporting Letter of Credit as required by Section 2.1.2(l)), (iii) the payment in full of all reimbursable expenses and other Obligations together with accrued and unpaid interest thereon, and (v) the payment in full of any amount due under Section 3.4.

2.18. Method of Payment.

(a) All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by 11 a.m. (Chicago time) with respect to all Swingline Loans and by noon (Chicago time) on the date when due and shall be applied ratably by the Agent among the Lenders except payments made on Swingline Loans, which shall be applied among the Lenders as provided in Section 2.1.3. Any payment received by the Agent or Swingline Lender after such time shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue. Solely for purposes of determining the amount of Loans available for borrowing purposes, checks

and cash or other immediately available funds from collections of items of payment and proceeds of any Collateral shall be applied in whole or in part against the Obligations, on the day of receipt, subject to actual collection. Each payment delivered to the Agent or Swingline Lender for the account of any Lender shall be delivered promptly by the Agent or Swingline Lender to such Lender in the same type of funds that the Agent or Swingline Lender received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent or Swingline Lender from such Lender.

(b) At the election of the Agent, all payments of principal, interest, reimbursement obligations in connection with Facility LCs, fees, premiums, reimbursable expenses (including, without limitation, all reimbursement for fees and expenses pursuant to Section 9.6), and other sums payable under the Loan Documents, may be paid from the proceeds of Advances made hereunder whether made following a request by the Borrower pursuant to Section 2.1 or a deemed request as provided in this Section 2.18 or may be deducted from the Funding Account or any other deposit account of the Borrower maintained with the Agent. The Borrower hereby irrevocably authorizes (i) the Agent to make an Advance for the purpose of paying each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Loan Documents and agrees that all such amounts charged shall constitute Loans (including Swingline Loans, Non-Ratable Loans and Protective Advances) and that all such Advances shall be deemed to have been requested pursuant to Section 2.1 and (ii) the Agent to charge the Funding Account or any other deposit account of the Borrower maintained with JPMorgan Chase Bank, N.A. for each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Loan Documents.

2.19. Apportionment, Application, and Reversal of Payments. Except as otherwise required pursuant to Section 2.1.3 or 2.20, principal and interest payments shall be apportioned ratably among the Lenders as set forth in this Article II and payments of the fees shall, as applicable, be apportioned ratably among the Lenders, except for fees payable solely to the Agent or the LC Issuer and except as provided in Section 2.10(c). All payments shall be remitted to the Agent and all such payments not relating to principal or interest of specific Loans or not constituting payment of specific fees as specified by the Borrower, and all proceeds of any Collateral received by the Agent, shall be applied, ratably, subject to the provisions of this Agreement, first, to pay any fees, indemnities, or expense reimbursements including amounts then due to the Agent from the Borrower (other than in connection with Banking Services or Rate Management Obligations), second, to pay any fees or expense reimbursements then due to the Lenders from the Borrower (other than in connection with Banking Services or Rate Management Obligations), third, to pay interest due in respect of the Protective Advances, fourth, to pay the principal of the Protective Advances, fifth, to pay interest due in respect of the Non-Ratable Loans, sixth, to pay interest due in respect of the Revolving Loans and Swingline Loans (other than Non-Ratable Loans and Protective Advances), seventh, to pay or prepay principal of the Non-Ratable Loans, eighth, to pay or prepay principal of the Revolving Loans and Swingline Loans (other than Non-Ratable Loans and Protective Advances) and unpaid reimbursement obligations in respect of Facility LCs, ninth, to pay an amount to the Agent equal to one hundred five percent (105%) of the aggregate undrawn face amount of all outstanding Facility LCs and the aggregate amount of any unpaid reimbursement obligations in respect of Facility LCs, to be held as cash collateral for such Obligations, tenth, to payment of any amounts owing with respect to Banking Services and Rate Management Obligations, and eleventh, to the payment of any other Secured Obligation due to the Agent or any Lender by the Borrower. Notwithstanding anything to the contrary contained in this Agreement, unless so directed by the Borrower, or unless a Default is in existence, neither the Agent nor any Lender shall apply any payment which it receives to any Eurodollar Loan, except (a) on the expiration date of the Interest Period applicable to any such Eurodollar Loan or (b) in the event, and only to the extent, that there are no outstanding Floating Rate Loans and, in any event, the Borrower shall pay the Eurodollar breakage losses in accordance with Section 3.4. The Agent and the Lenders shall have the continuing and exclusive right to apply and reverse and reapply any

and all such proceeds and payments to any portion of the Secured Obligations, so long as due in the same order provided herein.

2.20. Settlement. Except with respect to Swingline Loans, each Lender’s funded portion of the Loans is intended by the Lenders to be equal at all times to such Lender’s Pro Rata Share of the outstanding Loans. Notwithstanding such agreement, the Agent, JPMorgan Chase Bank, N.A., and the Lenders agree (which agreement shall not be for the benefit of or enforceable by the Loan Parties) that in order to facilitate the administration of this Agreement and the other Loan Documents, settlement among them as to the Loans, including the Non-Ratable Loans shall take place on a periodic basis as follows, except as otherwise provided in Section 2.1.3. The Agent shall request settlement (a “Settlement”) with the Lenders on at least a weekly basis, or on a more frequent basis at the Agent’s election, by notifying the Lenders of such requested Settlement by telecopy, telephone, or e-mail no later than 12:00 noon (Chicago, Illinois time) on the date of such requested Settlement (the “Settlement Date”). Each Lender (other than the Agent, in the case of the Non-Ratable Loans) shall transfer the amount of such Lender’s Pro Rata Share of the outstanding principal amount of the applicable Loan with respect to which Settlement is requested to the Agent, to such account of the Agent as the Agent may designate, not later than 2:00 p.m. (Chicago, Illinois time), on the Settlement Date applicable thereto. Settlements may occur during the existence of a Default or an Unmatured Default and whether or not the applicable conditions precedent set forth in Section 4.2 have then been satisfied. Such amounts transferred to the Agent shall be applied against the amounts of the applicable Loan and, together with JPMorgan Chase Bank, N.A.’s Pro Rata Share of such Non-Ratable Loan, shall constitute Revolving Loans of such Lenders, respectively. If any such amount is not transferred to the Agent by any Lender on the Settlement Date applicable thereto, the Agent shall be entitled to recover such amount on demand from such Lender together with interest thereon as specified in Section 2.24.

2.21. Indemnity for Returned Payments. If after receipt of any payment which is applied to the payment of all or any part of the Obligations, the Agent or any Lender is for any reason compelled to surrender such payment or proceeds to any Person because such payment or application of proceeds is invalidated, declared fraudulent, set aside, determined to be void or voidable as a preference, impermissible setoff, or a diversion of trust funds, or for any other reason, then the Obligations or part thereof intended to be satisfied shall be revived and continued and this Agreement shall continue in full force as if such payment or proceeds had not been received by the Agent or such Lender and the Borrower shall be liable to pay to the Agent and the Lenders, and the Borrower hereby indemnifies the Agent and the Lenders and holds the Agent and the Lenders harmless for the amount of such payment or proceeds surrendered except to the extent that they are determined in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Lenders. The provisions of this Section 2.21 shall be and remain effective notwithstanding any contrary action which may have been taken by the Agent or any Lender in reliance upon such payment or application of proceeds, and any such contrary action so taken shall be without prejudice to the Agent’s and the Lenders’ rights under this Agreement and shall be deemed to have been conditioned upon such payment or application of proceeds having become final and irrevocable. The provisions of this Section 2.21 shall survive the termination of this Agreement.

2.22. Noteless Agreement; Evidence of Indebtedness.

(a) 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 from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b) The Agent shall also maintain accounts in which it will record (i) the amount of each Loan extended hereunder, the Type thereof and the Interest Period with respect 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, (iii) the original stated amount of each Facility LC and the amount of LC Obligations outstanding at any time, and (iv) the

amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof.

(c) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d) Any Lender may request that its Revolving Loans be evidenced by a promissory note in substantially the form of Exhibit C (as amended, modified or supplemented from time to time, a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Revolving Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Revolving Loans once again be evidenced as described in paragraphs (a) and (b) above.

2.23. Lending Installations. Each Lender may book its Loans and its participation in any LC Obligations and the LC Issuer may book the Facility LCs at any Lending Installation selected by such Lender or the LC Issuer, as the case may be, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and any Notes issued hereunder shall be deemed held by each Lender or the LC Issuer, as the case may be, for the benefit of any such Lending Installation. Each Lender and the LC Issuer may, by written notice to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made.

2.24. Non-Receipt of Funds by the Agent; Defaulting Lenders.

(a) Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

(b) If a payment has not been made by a Lender, the Agent will notify the Borrower of such failure to fund and, upon demand by the Agent, the Borrower shall pay such amount to the Agent for the Agent’s account, together with interest thereon for each day elapsed since the Borrowing Date at a rate per annum equal to the interest rate applicable to the relevant Loan.

(c) The Agent shall not be obligated to transfer to a Defaulting Lender any payments made by the Borrower to the Agent for the Defaulting Lender’s benefit, and, in the absence of such transfer to the Defaulting Lender, the Agent shall transfer any such payments to each other non-Defaulting Lender ratably in accordance with their Pro Rata Share of the Commitments (but only to the extent that such Defaulting Lender’s Advance was funded by the other Lenders) or, if so directed by the Borrower and if no Unmatured Default or Default has occurred and is continuing (and to the extent such Defaulting Lender’s Advance was not funded by the other Lenders), retain the same to be re-advanced to the Borrower as if such Defaulting Lender had made Advances to the Borrower. Subject to the foregoing, the Agent may hold and, in its Permitted Discretion, setoff such Defaulting Lender’s funding shortfall against that Defaulting Lender’s Pro Rata Share of all payments received from the Borrower or re-lend to the Borrower for the account of such Defaulting Lender the amount of all such payments received and retained by the Agent for the account of such Defaulting Lender.

(d) Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(i) solely for the purposes of voting or consenting to matters with respect to the Loan Documents, such Defaulting Lender shall be deemed not to be a “Lender” and such Defaulting Lender’s Commitment shall be deemed to be zero ; provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender;

(ii) such Defaulting Lender shall not be entitled to any portion of the Unused Commitment Fee;

(iii) the Unused Commitment Fee shall accrue in favor of the Lenders which have funded their respective Pro Rata Shares of such requested Advance and shall be allocated among such non-Defaulting Lenders ratably based on their Pro Rata Share of the Commitments. This Section shall remain effective with respect to such Defaulting Lender until (x) the Obligations under this Agreement shall have been declared or shall have become immediately due and payable, (y) the non-Defaulting Lenders, the Agent, and the Borrower shall have waived such Defaulting Lender’s default in writing, or (z) the Defaulting Lender makes its Pro Rata Share of the applicable Advance and pays to Agent all amounts owing by the Defaulting Lender in respect thereof;

(iv) if any Swingline Exposure or LC Obligations exist at the time a Lender becomes a Defaulting Lender then:

(1) all or any part of such Swingline Exposure and LC Obligations shall be reallocated among the non-Defaulting Lenders in accordance with their respective Pro Rata Shares but only to the extent (x) the sum of all non-Defaulting Lenders’ Credit Exposures with respect to the Revolving Loans plus such Defaulting Lender’s Swingline Exposure and LC Obligations does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.2 are satisfied at such time; and

(2) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Agent (x) first, prepay such Swingline Exposure and (y) second, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.1.2 for so long as such LC Exposure is outstanding;

(3) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Obligations pursuant to Section 2.24(d)(iv), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.10(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(4) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 2.24(d)(iv), then the fees payable to the Lenders pursuant to Section 2.10(a) and Section 2.10(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Pro Rata Shares; or

(5) if any Defaulting Lender’s LC Obligations are neither cash collateralized nor reallocated pursuant to Section 2.24(d)(iv), then, without prejudice to any rights or remedies of the LC Issuer or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 2.10(b) with respect to such Defaulting Lender’s LC Obligations shall be payable to the LC Issuer until such LC Obligations are cash collateralized and/or reallocated;

(v) the Swingline Lender shall not be required to fund any Swingline Loan and the LC Issuer shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.24(d)(iv), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.24(d)(iv)(1) (and Defaulting Lenders shall not participate therein); and

(vi) in the event and on the date that each of the Agent, the Borrower, the LC Issuer and the Swingline Lender agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Obligations of the other Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders (other than Swingline Loans) as the Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Pro Rata Share.

(e) The operation of this Section shall not be construed to increase or otherwise affect the Commitment of any Lender, to relieve or excuse the performance by such Defaulting Lender or any other Lender of its duties and obligations hereunder, or to relieve or excuse the performance by the Borrower of its duties and obligations hereunder.

2.25. Limitation of Interest. The Borrower, the Agent and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section 2.25 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section 2.25, even if such provision declares that it controls. As used in this Section 2.25, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall the Borrower or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of Texas or the applicable laws (if any) of the U.S. or of any other applicable state, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Highest Lawful Rate. On each day, if any, that the interest rate (the “Stated Rate”) called for under this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document which directly or indirectly relate to interest shall ever be construed without reference to this Section 2.25, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the outstanding principal balance of the Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts (formerly TEX. REV. CIV. STAT. XXX. ART. 0000, Xx. 15)) shall not apply to this Agreement or to any Loan, nor shall this Agreement or any Loan be governed by or be subject to the provisions of such Chapter 346 in any manner whatsoever.

ARTICLE III

YIELD PROTECTION; TAXES

3.1. Yield Protection. If, on or after the Closing Date, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation or the LC Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(a) subjects any Lender or any applicable Lending Installation or the LC Issuer to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender or the LC Issuer in respect of its Eurodollar Loans, Facility LCs or participations therein, or

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation or the LC Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

(c) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation or the LC Issuer of making, funding or maintaining its Eurodollar Loans, or of issuing or participating in Facility LCs, or reduces any amount receivable by any Lender or any applicable Lending Installation or the LC Issuer in connection with its Eurodollar Loans, Facility LCs or participations therein, or requires any Lender or any applicable Lending Installation or the LC Issuer to make any payment calculated by reference to the amount of Eurodollar Loans, Facility LCs or participations therein held or interest or LC Fees received by it, by an amount deemed material by such Lender or the LC Issuer as the case may be,

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation or the LC Issuer, as the case may be, of making or maintaining its Eurodollar Loans or Commitment or of issuing or participating in Facility LCs or to reduce the return received by such Lender or applicable Lending Installation or the LC Issuer, as the case may be, in connection with such Eurodollar Loans, Commitment, Facility LCs or participations therein, then, within fifteen days of demand by such Lender or the LC Issuer, as the case may be, the Borrower shall pay such Lender or the LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the LC Issuer, as the case may be, for such increased cost or reduction in amount received.

3.2. Changes in Capital Adequacy Regulations. If a Lender or the LC Issuer determines the amount of capital required or expected to be maintained by such Lender or the LC Issuer, any Lending Installation of such Lender or the LC Issuer, or any corporation controlling such Lender or the LC Issuer is increased as a result of a Change, then, within fifteen days of demand by such Lender or the LC Issuer, the Borrower shall pay such Lender or the LC Issuer the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender or the LC Issuer determines is attributable to this Agreement, its Credit Exposure or its Commitment to make Loans and issue or participate in Facility LCs, as the case may be, hereunder (after taking into account such Lender’s or the LC Issuer’s policies as to capital adequacy). “Change” means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines (as defined below) or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or the LC Issuer or any Lending Installation or any corporation controlling any Lender or the LC Issuer. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect in the U.S. on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the U.S. implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

3.3. Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a

type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4.

3.4. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance except to the extent that any such loss or cost is determined in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Lenders.

3.5. Taxes.

(a) The Borrowers shall be jointly and severally liable for paying to the Agent any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required by applicable law to deduct any Indemnified Taxes or 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 Agent, Lender or LC Issuer (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrowers shall jointly and severally indemnify the Agent, each Lender and the LC Issuer, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Agent, such Lender or the LC Issuer, as the case may be, on or with respect to any payment by the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) 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 delivered to the Borrower by a Lender or the LC Issuer, or by the Agent on its own behalf or on behalf of a Lender or the LC Issuer, shall be conclusive absent manifest error.

(d) Each Lender and the LC Issuer shall indemnify the Borrower and the Agent, within 10 days after written demand therefor, against any and all Taxes and any and all related losses, claims, liabilities, penalties, interest and reasonable expenses (including the fees, charges and disbursements of any counsel for the Borrower or the Agent) incurred by or asserted against the Borrower or the Agent by any Governmental Authority as a result of the failure by such Lender or the LC Issuer, as the case may be, to deliver, or as a result of the inaccuracy, inadequacy or deficiency of, any documentation required to be delivered to the Borrower or the Agent pursuant to Section 3.5(f). Each Lender and the LC Issuer hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender or the LC Issuer, as the case may be, under this Agreement or any other Loan

Document against any amount due to the Agent under this Section 3.5(d). The obligations of the Lenders under this Section 3.5(d) shall survive the payment of the Obligations and termination of this Agreement.

(e) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the 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 Agent.

(f) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, if any payment made hereunder or under any other Loan Document would be subject to United States federal withholding tax imposed pursuant to FATCA if the recipient of such payment fails to comply with applicable reporting and other requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such recipient shall use commercially reasonable efforts to deliver to the Borrower and the Agent, at the time or times prescribed by applicable law or as reasonably requested by the Borrower or the Agent, (A) two accurate, complete and signed certifications prescribed by applicable law and/or reasonably satisfactory to the Borrower and the Agent that establish that such payment is exempt from United States federal withholding tax imposed pursuant to FATCA and (B) any other documentation reasonably requested by the Borrower or the Agent sufficient for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such recipient has complied with such applicable reporting and other requirements of FATCA.

(g) If the Agent or a Lender determines 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 3.5, it shall pay over an amount equal to such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 3.5 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Agent or such Lender 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 Agent or such Lender, agree to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Agent or such Lender in the event the Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

3.6. Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar

Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Adjusted LIBO Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

3.7. Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 or if any Lender is a Defaulting Lender (any such Lender, an “Affected Lender”), the Borrower, at its sole expense and effort, upon notice to such Lender and the Agent, may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement (in accordance with and subject to the restrictions contained in Article XII), provided that, no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided further that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower, the Agent and LC Issuer shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an Assignment Agreement (and a Defaulting Lender shall be deemed to have executed and delivered such an Assignment Agreement if it fails to do so) and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

Each Loan Party jointly and severally represents and warrants to Lenders as follows:

5.1. Existence and Standing. Each Loan Party is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect, has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

5.2. Authorization and Validity. Each Loan Party has the power and authority and legal right to execute and deliver the Loan Documents to which it is a party and to perform its obligations thereunder. The execution and delivery by each Loan Party of the Loan Documents to which it is a party and the performance of its obligations thereunder have been duly authorized by proper proceedings, and the Loan Documents to which such Loan Party is a party constitute legal, valid and binding obligations of such Loan Party enforceable against such Loan Party in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally.

5.3. No Conflict; Government Consent. Neither the execution and delivery by any Loan Party of the Loan Documents to which it is a party, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on such Loan Party or (ii) any Loan Party’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any material indenture, instrument or agreement to which any Loan Party is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of such Loan Party pursuant to the terms of any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by a Loan Party, is required to be obtained by any Loan Party in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Loan Parties of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents.

5.4. Security Interest in Collateral. The provisions of this Agreement and the other Loan Documents create legal and valid Liens on all the Collateral in favor of the Agent, for the benefit of the Agent and the Lenders, and upon the recording of financing statements covering the Collateral in the state of organization of the applicable Loan Party, such Liens constitute perfected and continuing Liens on the Collateral, securing the Obligations, enforceable against the applicable Loan Party and all third parties, and having priority over all other Liens on the Collateral except in the case of (a) Permitted Liens, to the extent any such Permitted Liens would have priority over the Liens in favor of the Agent pursuant to any applicable law and (b) Liens perfected only by possession (including possession of any certificate of title) to the extent the Agent has not obtained or does not maintain possession of such Collateral.

5.5. Financial Statements.

(a) The audited consolidated financial statements of the Borrower and its Subsidiaries for the period ending on December 31, 2009 heretofore delivered to the Lenders were prepared in accordance with GAAP (as in effect on the date such statements were prepared) and fairly present the consolidated financial condition and operations of the Borrower and its Subsidiaries at such date and the consolidated results of their operations for the period then ended. The unaudited interim financial statements of the Borrower and its Subsidiaries for the period ended October 31, 2010 heretofore delivered by the Borrower to the Lenders were prepared in accordance with GAAP (as in effect on the date such statements were prepared except for the presentation of footnotes and for applicable normal year-end audit adjustments) and fairly present the consolidated financial condition and operations of the Borrower and its Subsidiaries at such date and the consolidated results of their operations for the period then ended.

(b) The most recent Budget delivered to the Agent and the Lenders pursuant to Section 6.1(c), represent the Borrower’s good faith estimate of anticipated financial performance of the Borrower for the period set forth therein based upon assumptions believed by Borrower to be reasonable at the time of such delivery, but shall not constitute or be deemed to constitute a representation or warranty that such anticipated performance will in fact be achieved. Whether or not any such results are in fact achieved will depend upon future events, some of which are not within the control of the Borrower. Accordingly (but without limiting the first sentence of this Section 5.5(b)), actual results may vary from the projected results.

5.6. Material Adverse Change. Since December 31, 2009 there has been no change in the business, Collateral Property, condition (financial or otherwise) or results of operations of the Loan Parties or other event which could reasonably be expected to have a Material Adverse Effect.

5.7. Taxes. The Loan Parties have filed all U.S. federal tax returns and all other tax returns which are required to be filed and have paid all taxes due pursuant to said returns or pursuant to any assessment received by any Loan Party, except such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided in accordance with GAAP and as to which no Lien exists. No tax liens have been filed and, to Borrower’s knowledge, no claims are being asserted with respect to any such taxes. The charges, accruals and reserves on the books of the Loan Parties in respect of any taxes or other governmental charges are adequate.

5.8. Litigation and Contingent Obligations. Except as set forth on Schedule 5.8, there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting any Loan Party which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of any Credit Extensions.

The Agent may permit or require any Loan Party to use such money, or any part thereof, to replace, repair, restore or rebuild the Collateral in a diligent and expeditious manner with materials and workmanship of substantially the same quality as existed before the loss, damage or destruction. Notwithstanding the foregoing, if the casualty giving rise to such insurance proceeds could not reasonably be expected to have a Material Adverse Effect and such insurance proceeds do not exceed $1,000,000 in the aggregate, upon the applicable Loan Party’s request, the Agent shall permit such Loan Party to replace, restore, repair or rebuild the property; provided that, if such Loan Party has not completed or entered into binding agreements to complete such replacement, restoration, repair or rebuilding within ninety days of such casualty, the Agent may apply such insurance proceeds to the Obligations in accordance with Section 2.15.

the Agent an amount, in immediately available funds (which funds shall be held in the Facility LC Collateral Account), equal to 105% of the Collateral Shortfall Amount or (2) deliver a Supporting Letter of Credit as required by Section 2.1.2(l), whichever the Agent may specify in its sole discretion, (v) increase the rate of interest applicable to the Loans and the LC Fees as set forth in this Agreement and (vi) exercise any rights and remedies provided to the Agent or any Lender under the Loan Documents or at law or equity, including all remedies provided under the UCC.

(b) If any Default described in subsections (f) or (g) of Article VII occurs with respect to any Loan Party, the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs shall automatically terminate and all Obligations shall immediately become due and payable without any election or action on the part of the Agent, the LC Issuer or any Lender and the Loan Parties will be and become thereby unconditionally obligated, without any further notice, act or demand, to pay to the Agent an amount equal to 105% of the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

(c) If, within thirty days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans and the obligation and power of the LC Issuer to issue Facility LCs hereunder as a result of any Default (other than any Default as described in subsections (f) or (g) of Article VII with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

(d) If at any time while any Default is continuing, the Agent determines that the Collateral Shortfall Amount at such time is greater than zero, the Agent may make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Agent an amount equal to 105% of the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account. The Borrower hereby pledges, assigns, and grants to the Agent, on behalf of and for the benefit of the Agent, the Lenders, and the LC Issuer, a security interest in all of the Borrower’ right, title, and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and complete payment and performance of the Obligations.

(b) Notwithstanding subsection (a) above, no such amendment, waiver or other modification (I) [Intentionally Omitted], or (II) with respect to this Agreement shall, without the consent of all of the Lenders:

(iv) amend the definition of Required Lenders;

(v) extend the Facility Termination Date;

(vi) increase the amount of the Aggregate Commitment (other than pursuant to Section 2.1.1(ii)) or the Commitment of any Lender hereunder (other than pursuant to Section 12.3);

(vii) increase the advance rates set forth in the definition of Borrowing Base;

(viii) [Reserved];

(ix) amend this Section 8.3 or Section 10.15;

(x) release any guarantor from the Guaranteed Obligations, except as otherwise permitted herein or in the other Loan Documents; or

(xi) except as provided in Section 10.15 or any Collateral Document, release all or substantially all of the Collateral.

(c) No amendment of any provision of this Agreement relating to the Agent or to the Non-Ratable Loans or the Protective Advances shall be effective without the written consent of the Agent. No amendment of any provision relating to the LC Issuer shall be effective without the written consent of the LC Issuer.

(d) If, in connection with any proposed amendment, waiver or consent (a “Proposed Change”) requiring the consent of all Lenders, the consent of the Required Lenders is obtained, but the consent of other Lenders is not obtained (any such Lender whose consent is not obtained being referred to herein as a “Non-Consenting Lender”), then, so long as the Agent is not a Non-Consenting Lender, the Borrower may elect to replace such Non-Consenting Lender as a Lender party to this Agreement, provided that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Non-Consenting Lender pursuant to an Assignment Agreement and to become a Lender for all purposes under this Agreement and to assume all obligations of the Non-Consenting Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Non-Consenting Lender in same day funds on the day of such replacement (1) all interest, fees and other amounts then accrued but unpaid to such Non-Consenting Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Non-Consenting Lender under Sections 3.1, 3.2 and 3.5, and (2) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Non-Consenting Lender been prepaid on such date rather than sold to the replacement Lender.

8.4. Preservation of Rights. No delay or omission of the Lenders, the LC Issuer or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.3, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be cumulative and all shall be available to the Agent, the LC Issuer and the Lenders until the Obligations have been paid in full.

9.9. Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have

any liability with respect to, and each Loan Party hereby waives, releases and agrees not to xxx for, any special, indirect, consequential or punitive damages suffered by any Loan Party in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

9.11. Confidentiality.

9.14. Patriot Act Notice. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the names and addresses of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for the Borrower: When the Borrower opens an account, if the Borrower is an individual, the Agent and the Lenders will ask for the Borrower’s name, residential address, date of birth, and other information that will allow Agent and the Lenders to identify the Borrower, and, if the Borrower is not an individual, the Agent and the Lenders will ask for the Borrower’s name, employer identification number, business address, and other information that will allow the Agent and the Lenders to identify the Borrower.

The Agent and the Lenders may also ask, if the Borrower is an individual, to see the Borrower’s driver’s license or other identifying documents, and, if the Borrower is not an individual, to see the Borrower’s legal organizational documents or other identifying documents.

For purposes of determining compliance with the conditions specified in Sections 4.1 and 4.2, each Lender that has signed this Agreement 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 a Lender unless the Agent shall have received notice from such Lender prior to the applicable date specifying its objection thereto.

10.8. Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (a) for any amounts not reimbursed by the Borrower for which the Agent other than Rate Management Obligations and Banking Services Obligations is entitled to reimbursement by the Borrower under the Loan Documents, (b) for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders) and (c) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that, (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent and (ii) any indemnification required pursuant to Section 3.5(d) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9. Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default.” In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders; provided, that, the Agent shall not be liable to any Lender for

any failure to do so, except to the extent that such failure is attributable to the Agent’s gross negligence or willful misconduct.

10.10. Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Credit Extensions as any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with any Loan Party in which such Loan Party is not restricted hereby from engaging with any other Person, all as if JPMorgan Chase Bank, N.A. were not the Agent and without any duty to account therefor to the Lenders. JPMorgan Chase Bank, N.A. and its Affiliates may accept fees and other consideration from any Loan Party for services in connection with this Agreement or otherwise without having to account for the same to the Lenders. The Agent in its individual capacity, is not obligated to remain a Lender.

10.11. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Loan Parties and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents. Except for any notice, report, document, credit information or other information expressly required to be furnished to the Lenders by the Agent or Arranger hereunder, neither the Agent nor the Arranger shall have any duty or responsibility (either initially or on a continuing basis) to provide any Lender with any notice, report, document, credit information or other information concerning the affairs, financial condition or business of the Borrower or any of its Affiliates that may come into the possession of the Agent or Arranger (whether or not in their respective capacity as Agent or Arranger) or any of their Affiliates.

10.12. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan

Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

10.13. Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X.

10.14. Execution of Loan Documents. The Lenders hereby empower and authorize the Agent, on behalf of the Agent and the Lenders, to execute and deliver to the Loan Parties the Loan Documents and all related agreements, certificates, documents, or instruments as shall be necessary or appropriate to effect the purposes of the Loan Documents. Each Lender agrees that any action taken by the Agent or the Required Lenders or (to the extent required hereunder, all Lenders) in accordance with the terms of this Agreement or the other Loan Documents, and the exercise by the Agent or the Required Lenders or (to the extent required hereunder, all Lenders) of their respective powers set forth therein or herein, together with such other powers that are reasonably incidental thereto, shall be binding upon all of the Lenders. The Lenders acknowledge that all of the Obligations hereunder constitute one debt, secured pari passu by all of the Collateral.

10.15. Collateral Matters.

(a) The Lenders hereby irrevocably authorize the Agent, at its option and in its sole discretion, to release any Liens granted to the Agent by the Loan Parties on any Collateral (i) upon the termination of the Aggregate Commitment, payment and satisfaction in full in cash of all Obligations (other than LC Obligations), and the cash collateralization of all LC Obligations in a manner satisfactory to each affected Lender, (ii) constituting Property being sold or disposed of if the Loan Party disposing of such Property certifies to the Agent that the sale or disposition is made in compliance with the terms of this Agreement (and the Agent may rely conclusively on any such certificate, without further inquiry), (iii) constituting Property in which no Loan Party has at any time during the term of this Agreement owned any interest, (iv) constituting property leased to a Loan Party under a lease which has expired or been terminated in a transaction permitted under this Agreement, (v) owned by or leased to an Loan Party which is subject to a purchase money security interest or which is the subject of a Capitalized Lease, in either case, entered into by such Loan Party pursuant to Section 6.17(c) or Section 6.17(g), or (vi) as required to effect any sale or other disposition of such Collateral in connection with any exercise of remedies of the Agent and the Lenders pursuant to Section 8.1. Upon request by the Agent at any time, the Lenders will confirm in writing the Agent’s authority to release any Liens upon particular types or items of Collateral pursuant to this Section 10.15. Except as provided in the preceding sentence, the Agent will not release any Liens on Collateral without the prior written authorization of the Required Lenders; provided that, the Agent may in its discretion, release its Liens on Collateral valued in the aggregate not in excess of $2,500,000 during any calendar year without the prior written authorization of the Lenders.

(b) Upon receipt by the Agent of any authorization required pursuant to Section 10.15(a) from the Required Lenders of the Agent’s authority to release any Liens upon particular types or items of Collateral, and upon at least five Business Days prior written request by the Loan Parties, the Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents as may be necessary to evidence the release of its Liens upon such Collateral; provided that, (i) the Agent shall not be required to execute any such document on terms which, in the Agent’s opinion, would expose the Agent to liability or create any obligation or entail any consequence other than the release of such Liens

without recourse or warranty and (ii) such release shall not in any manner discharge, affect, or impair the Obligations or any Liens (other than those expressly being released) upon (or obligations of the Loan Parties in respect of) all interests retained by the Loan Parties, including the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

(c) The Agent shall have no obligation whatsoever to any of the Lenders to assure that the Collateral exists or is owned by the Loan Parties or is cared for, protected, or insured or has been encumbered, or that the Liens granted to the Agent therein have been properly or sufficiently or lawfully created, perfected, protected, or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Agent pursuant to any of the Loan Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Agent may act in any manner it may deem appropriate, in its sole discretion given the Agent’s own interest in the Collateral in its capacity as one of the Lenders and that the Agent shall have no other duty or liability whatsoever to any Lender as to any of the foregoing.

(d) Each Lender hereby appoints each other Lender as its agent for the purpose of perfecting Liens, for the benefit of the Agent and the Lenders, in assets which, in accordance with Article 9 of the UCC or any other applicable law can be perfected only by possession. Should any Lender (other than the Agent) obtain possession of any such Collateral, such Lender shall notify the Agent thereof, and, promptly upon the Agent’s request therefor shall deliver such Collateral to the Agent or otherwise deal with such Collateral in accordance with the Agent’s instructions.

Each Lender hereby agrees as follows: (a) such Lender is deemed to have requested that the Agent furnish such Lender, promptly after it becomes available, a copy of each Report prepared by or on behalf of the Agent; (b) such Lender expressly agrees and acknowledges that neither JPMorgan Chase Bank, N.A. nor the Agent (i) makes any representation or warranty, express or implied, as to the completeness or accuracy of any Report or any of the information contained therein, or (ii) shall be liable for any information contained in any Report; (c) such Lender expressly agrees and acknowledges that the Reports are not comprehensive audits or examinations, that the Agent, JPMorgan Chase Bank, N.A., or any other party performing any audit or examination will inspect only specific information regarding the Loan Parties and will rely significantly upon the Loan Parties’ books and records, as well as on representations of the Loan Parties’ personnel and that JPMorgan Chase Bank, N.A. undertakes no obligation to update, correct or supplement the Reports; (d) such Lender agrees to keep all Reports confidential and strictly for its internal use, not share the Report with any Loan Party and not to distribute any Report to any other Person except as otherwise permitted pursuant to this Agreement; and (e) without limiting the generality of any other indemnification provision contained in this Agreement, such Lender agrees (i) that neither JPMorgan Chase Bank, N.A. nor the Agent shall be liable to such Lender or any other Person receiving a copy of the Report for any inaccuracy or omission contained in or relating to a Report, (ii) to conduct its own due diligence investigation and make credit decisions with respect to the Loan Parties based on such documents as such Lender deems appropriate without any reliance on the Reports or on the Agent or JPMorgan Chase Bank, N.A., (iii) to hold the Agent and any such other Person preparing a Report harmless from any action the indemnifying Lender may take or conclusion the indemnifying Lender may reach or draw from any Report in connection with any Credit Extensions that the indemnifying Lender has made or may make to the Loan Parties, or the indemnifying Lender’s participation in, or the indemnifying Lender’s purchase of, any Obligations and (iv) to pay and protect, and indemnify, defend, and hold the Agent and any such other Person preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including reasonable attorney fees) incurred by the Agent and any such other Person preparing a Report as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender.

10.16. Co-Agents, Documentation Agent, Syndication Agent, etc.. Neither any of the Lenders identified in this Agreement as a “co-agent” nor the Documentation Agent or the Syndication Agent shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgments with respect to such Lenders as it makes with respect to the Agent in Section 10.11.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Loan Party becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Secured Obligations owing to such Lender, whether or not the Secured Obligations, or any part thereof, shall then be due.

11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Credit Exposure (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Credit Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Secured Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to respective Pro Rata Share of the Aggregate Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Loan Parties and the Lenders and their respective successors and assigns permitted hereby, except that (a) the Loan Parties shall not have the right to assign their rights or obligations under the Loan Documents without the prior written consent of each Lender, (b) any assignment by any Lender must be made in compliance with Section 12.3, and (c) any transfer by Participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.2. The parties to this Agreement acknowledge that clause (b) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat the Person which made any Credit Extension or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided however, that the Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Credit Extension

or which holds any Note to direct payments relating to such Credit Extension or Note to another Person. Any assignee of the rights to any Credit Extension or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Credit Extension (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Credit Extension.

12.2. Participations.

(a) Permitted Participants; Effect. Any Lender may at any time sell to one or more banks or other entities (“Participants”) participating interests in any Credit Exposure of such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.

(b) Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.3 or of any other Loan Document.

(c) Benefit of Certain Provisions. Each Loan Party agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that, each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3, provided that, (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the U.S. or any state thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender.

12.3. Assignments.

(a) Permitted Assignments. Any Lender may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the

Loan Documents. Such assignment shall be substantially in the form of Exhibit G (an “Assignment Agreement”). Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Credit Extensions of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or outstanding Credit Extensions (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment.

(b) Consents. The consent of the Borrower (which shall not be unreasonable withheld or delayed) shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund, provided that, the consent of the Borrower shall not be required if a Default has occurred and is continuing. The consent of the Agent shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund. The consent of the LC Issuer and Swingline Lender shall be required prior to an assignment of a Commitment becoming effective unless the Purchaser is a Lender with a Commitment. Any consent required under this Section 12.3(b) shall not be unreasonably withheld or delayed.

(c) Effect; Effective Date. Upon (i) delivery to the Agent of a duly executed Assignment Agreement, together with any consents required by Sections 12.3(a) and 12.3(b), and (ii) payment of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such Assignment Agreement shall become effective on the effective date specified by the Agent in such Assignment Agreement. The Assignment Agreement shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Credit Exposure under the applicable Assignment Agreement constitutes “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such Assignment Agreement, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an Assignment Agreement covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the applicable agreement. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 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 Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3(c), the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(d) Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the U.S. a copy of each Assignment

Agreement 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 Credit Extensions 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 Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

12.4. Dissemination of Information. Each Loan Party authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any Reports; provided that, each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the U.S. or any state thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5.

12.6. Assignment by LC Issuer. Notwithstanding anything contained herein, if at any time JPMorgan Chase Bank, N.A. assigns all of its Commitment and Revolving Loans pursuant to Section 12.3, JPMorgan Chase Bank, N.A. may, upon thirty days’ notice to the Borrower and the Lenders, resign as LC Issuer. In the event of any such resignation as LC Issuer, the Borrower shall be entitled to appoint from among the Lenders a successor LC Issuer (other xxxx Xxxxxxx Xxxxx Capital) hereunder; provided however, that no failure by the Borrower to appoint any such successor shall affect the resignation of JPMorgan Chase Bank, N.A. as LC Issuer. If JPMorgan Chase Bank, N.A. resigns as LC Issuer, it shall retain all the rights and obligations of the LC Issuer hereunder with respect to the Facility LCs outstanding as of the effective date of its resignation as LC Issuer and all LC Obligations with respect thereto (including the right to require the Lenders to make Revolving Loans or fund risk participations in outstanding Reimbursement Obligations pursuant to Section 2.1.2(d)).

12.7. Assignment by Swingline Lender. Notwithstanding anything contained herein, if at any time JPMorgan Chase Bank, N.A. assigns all of its Commitment and Revolving Loans pursuant to Section 12.3, JPMorgan Chase Bank, N.A. may, upon thirty days’ notice to the Borrower and the Lenders, resign as Swingline Lender. In the event of any such resignation as Swingline Lender, the Borrower shall be entitled to appoint from among the Lenders a successor Swingline Lender (other xxxx Xxxxxxx Xxxxx Capital) hereunder; provided however, that no failure by the Borrower to appoint any such successor shall affect the resignation of JPMorgan Chase Bank, N.A. as Swingline Lender. If JPMorgan Chase Bank, N.A. resigns as Swingline Lender, it shall retain all the rights and obligations of the Swingline Lender hereunder with respect to the Swingline Loans outstanding as of the effective date of its resignation as Swingline Lender and all Swingline Loans with respect thereto (including the right to require the Lenders to make Revolving Loans or fund risk participations in outstanding Reimbursement Obligations pursuant to Section 2.1.3).

GUARANTY

15.1. Guaranty. Each Guarantor hereby agrees that it is jointly and severally liable for, and, as primary obligor and not merely as surety, absolutely and unconditionally guarantees to the Lenders the prompt payment when due, whether at stated maturity, upon acceleration or otherwise, and at all times thereafter, of the Secured Obligations and all costs and expenses including, without limitation, all court costs and attorneys’ and paralegals’ fees (including allocated costs of in-house counsel and paralegals) and expenses paid or incurred by the Agent, the LC Issuer and the Lenders in endeavoring to collect all or any part of the Secured Obligations from, or in prosecuting any action against, the Borrower, any Guarantor or any other guarantor of all or any part of the Secured Obligations (such costs and expenses, together with the Secured Obligations, collectively the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed in whole or in part without notice to or further assent from it, and that it remains bound upon its guarantee notwithstanding any such extension or renewal.

15.2. Guaranty of Payment. This Guaranty is a guaranty of payment and not of collection. Each Guarantor waives any right to require the Agent, the LC Issuer or any Lender to xxx the Borrower, any Guarantor, any other guarantor, or any other person obligated for all or any part of the Guaranteed Obligations, or otherwise to enforce its payment against any collateral securing all or any part of the Guaranteed Obligations.

15.3. No Discharge or Diminishment of Guaranty.

(a) Except as otherwise provided for herein and to the extent provided for herein, the obligations of each Guarantor hereunder are unconditional and absolute and not subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed Obligations), including:

(i) any claim of waiver, release, extension, renewal, settlement, surrender, alteration, or compromise of any of the Guaranteed Obligations, by operation of law or otherwise;

(ii) any change in the corporate existence, structure or ownership of the Borrower or any other guarantor of or other person liable for any of the Guaranteed Obligations;

(iii) any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower, any Guarantor, or any other guarantor of or other person liable for any of the Guaranteed Obligations, or their assets or any resulting release or discharge of any obligation of the Borrower, any Guarantor, or any other guarantor of or other person liable for any of the Guaranteed Obligations; or

(iv) the existence of any claim, setoff or other rights which any Guarantor may have at any time against the Borrower, any Guarantor, any other guarantor of the Guaranteed Obligations, the Agent, the LC Issuer, any Lender, or any other person, whether in connection herewith or in any unrelated transactions.

(b) The obligations of each Guarantor hereunder are not subject to any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, or unenforceability of any of the Guaranteed Obligations or otherwise, or any provision of applicable law or regulation purporting to prohibit payment by the Borrower, any Guarantor or any other guarantor of or other person liable for any of the Guaranteed Obligations, of the Guaranteed Obligations or any part thereof.

(i) the failure of the Agent, the LC Issuer or any Lender to assert any claim or demand or to enforce any remedy with respect to all or any part of the Guaranteed Obligations;

(ii) any waiver or modification of or supplement to any provision of any agreement relating to the Guaranteed Obligations;

(iii) any release, non-perfection, or invalidity of any indirect or direct security for the obligations of the Borrower for all or any part of the Guaranteed Obligations or any obligations of any other guarantor of or other person liable for any of the Guaranteed Obligations;

(iv) any action or failure to act by the Agent, the LC Issuer or any Lender with respect to any collateral securing any part of the Guaranteed Obligations;

(v) any default, failure or delay, willful or otherwise, in the payment or performance of any of the Guaranteed Obligations, or any other circumstance, act, omission or delay that might in any manner or to any extent vary the risk of such Guarantor or that would otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of the Guaranteed Obligations).

15.4. Defenses Waived. To the fullest extent permitted by applicable law, each Guarantor hereby waives any defense based on or arising out of any defense of the Borrower or any Guarantor or the unenforceability of all or any part of the Guaranteed Obligations from any cause, or the cessation from any cause of the liability of the Borrower or any Guarantor, other than the indefeasible payment in full in cash of the Guaranteed Obligations. Without limiting the generality of the foregoing, each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any person against the Borrower, any Guarantor, any other guarantor of any of the Guaranteed Obligations, or any other person. The Agent may, at its election, foreclose on any Collateral held by it by one or more judicial or nonjudicial sales, accept an assignment of any such Collateral in lieu of foreclosure or otherwise act or fail to act with respect to any collateral securing all or a part of the Guaranteed Obligations, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with the Borrower, any Guarantor, any other guarantor or any other person liable on any part of the Guaranteed Obligations or exercise any other right or remedy available to it against the Borrower, any Guarantor, any other guarantor or any other person liable on any of the Guaranteed Obligations, without affecting or impairing in any way the liability of such Guarantor

under this Guaranty except to the extent the Guaranteed Obligations have been fully and indefeasibly paid in cash. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though that election may operate, pursuant to applicable law, to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Guarantor against the Borrower, any other guarantor or any other person liable on any of the Guaranteed Obligations, as the case may be, or any security.

15.5. Rights of Subrogation. No Guarantor will assert any right, claim or cause of action, including, without limitation, a claim of subrogation, contribution or indemnification that it has against the Borrower, any Guarantor, any person liable on the Guaranteed Obligations, or any collateral, until the Loan Parties and the Guarantors have fully performed all their obligations to the Agent, the LC Issuer and the Lender.

15.6. Reinstatement; Stay of Acceleration. If at any time any payment of any portion of the Guaranteed Obligations is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, or reorganization of the Borrower or otherwise, each Guarantor’s obligations under this Guaranty with respect to that payment shall be reinstated at such time as though the payment had not been made and whether or not the Agent, the LC Issuer and the Lenders are in possession of this Guaranty. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all such amounts otherwise subject to acceleration under the terms of any agreement relating to the Guaranteed Obligations shall nonetheless be payable by the Guarantors forthwith on demand by the Lender.

15.7. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that each Guarantor assumes and incurs under this Guaranty, and agrees that neither the Agent, the LC Issuer nor any Lender shall have any duty to advise any Guarantor of information known to it regarding those circumstances or risks.

15.8. Termination. The Lenders may continue to make loans or extend credit to the Borrower based on this Guaranty until five days after it receives written notice of termination from any Guarantor. Notwithstanding receipt of any such notice, each Guarantor will continue to be liable to the Lender for any Guaranteed Obligations created, assumed or committed to prior to the fifth day after receipt of the notice, and all subsequent renewals, extensions, modifications and amendments with respect to, or substitutions for, all or any part of that Guaranteed Obligations.

15.9. Taxes. All payments of the Guaranteed Obligations will be made by each Guarantor free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any Guarantor shall be required to deduct any Indemnified Taxes or 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 Agent, Lender or LC Issuer (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Guarantor shall make such deductions and (iii) such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

15.10. Severability. The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the amount of such liability shall, without any further action by the Guarantors or the Lenders, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in

such action or proceeding (such highest amount determined hereunder being the relevant Guarantor’s “Maximum Liability”. This Section with respect to the Maximum Liability of each Guarantor is intended solely to preserve the rights of the Lenders to the maximum extent not subject to avoidance under applicable law, and no Guarantor nor any other person or entity shall have any right or claim under this Section with respect to such Maximum Liability, except to the extent necessary so that the obligations of any Guarantor hereunder shall not be rendered voidable under applicable law. Each Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of each Guarantor without impairing this Guaranty or affecting the rights and remedies of the Lenders hereunder, provided that, nothing in this sentence shall be construed to increase any Guarantor’s obligations hereunder beyond its Maximum Liability.

15.11. Contribution. In the event any Guarantor (a “Paying Guarantor”) shall make any payment or payments under this Guaranty or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations under this Guaranty, each other Guarantor (each a “Non-Paying Guarantor”) shall contribute to such Paying Guarantor an amount equal to such Non-Paying Guarantor’s “Pro Rata Share” of such payment or payments made, or losses suffered, by such Paying Guarantor. For purposes of this Article XV, each Non-Paying Guarantor’s “Pro Rata Share” with respect to any such payment or loss by a Paying Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (i) such Non-Paying Guarantor’s Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Guarantor’s Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Guarantor from the Borrower after the date hereof (whether by loan, capital infusion or by other means) to (ii) the aggregate Maximum Liability of all Guarantors hereunder (including such Paying Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any Guarantor, the aggregate amount of all monies received by such Guarantors from the Borrower after the date hereof (whether by loan, capital infusion or by other means). Nothing in this provision shall affect any Guarantor’s several liability for the entire amount of the Guaranteed Obligations (up to such Guarantor’s Maximum Liability). Each of the Guarantors covenants and agrees that its right to receive any contribution under this Guaranty from a Non-Paying Guarantor shall be subordinate and junior in right of payment to the payment in full in cash of the Guaranteed Obligations. This provision is for the benefit of both the Agent, the LC Issuer, the Lenders and the Guarantors and may be enforced by any one, or more, or all of them in accordance with the terms hereof.

15.12. Lending Installations. The Guaranteed Obligations may be booked at any Lending Installation. All terms of this Guaranty apply to and may be enforced by or on behalf of any Lending Installation.

15.13. Liability Cumulative. The liability of each Loan Party as a Guarantor under this Article XV is in addition to and shall be cumulative with all liabilities of each Loan Party to the Agent, the LC Issuer and the Lenders under this Agreement and the other Loan Documents to which such Loan Party is a party or in respect of any obligations of liabilities of the other Loan Parties, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT, THE LC ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST ANY LOAN PARTY IN THE COURTS OF ANY OTHER JURISDICTION.

16.3. WAIVER OF JURY TRIAL. EACH LOAN PARTY, THE AGENT, THE LC ISSUER AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

Each Borrower hereby agrees that such Borrower is jointly and severally liable for, and hereby absolutely and unconditionally guarantees to Agent and Lenders and its successors and assigns, the full and prompt payment (whether at stated maturity, by acceleration or otherwise) and performance of, all Obligations owed or hereafter owing to Lenders by each other Borrower. Each Borrower agrees that its guaranty obligation hereunder is a continuing guaranty of payment and performance and not of collection, that its obligations under this Article 18 shall not be discharged until payment and performance, in full, of the Obligations has occurred, and that its obligations under this Article 18 shall be absolute and unconditional, irrespective of, and unaffected by,

(a) the genuineness, validity, regularity, enforceability or any future amendment of, or change in, this Agreement, any other Loan Document or any other agreement, document or instrument to which the Borrower is or may become a party;

(b) the absence of any action to enforce this Agreement (including this Article 18) or any other Loan Document or the waiver or consent by Agent or any Lender with respect to any of the provisions thereof;

101

(c) the existence, value or condition of, or failure to perfect its Lien against, any security for the Obligations or any action, or the absence of any action, by Agent or any Lender in respect thereof (including the release of any such security);

(d) the insolvency of the Borrower; or

(e) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor.

18.2. Waivers By Borrower.

(a) Each Borrower expressly waives all rights it may have now or in the future under any statute, or at common law, or at law or in equity, or otherwise, to compel Agent or any Lender to marshal assets or to proceed in respect of the Obligations guaranteed hereunder against any other Borrower, any other party or against any security for the payment and performance of the Obligations before proceeding against, or as a condition to proceeding against, such Borrower.

(b) To the maximum extent permitted by law, the Borrower, in its capacity as a surety as a result of joint and several obligations hereunder, hereby waives and agrees not to assert or take advantage of: (i) the unenforceability or invalidity of any security or guaranty or the lack of perfection or continuing perfection, or failure of priority of any security for the Obligations; (ii) any and all rights and defenses arising out of an election of remedies by Agent or any Lender; (iii) any defense based upon any failure to disclose to such Borrower any information concerning the financial condition of any other Borrower or any other Person or any other circumstances bearing on the ability of any other Borrower or any other Person to pay and perform all obligations due under this Agreement or any of the other Loan Documents; (iv) any failure of Agent or any Lender to comply with applicable laws in connection with the sale or disposition of security, including, without limitation, any failure by the Agent or any Lender to conduct a commercially reasonable sale or other disposition of such security; (v) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in any other respects more burdensome than that of a principal, or that reduces a surety’s or guarantor’s obligations in proportion to the principal’s obligation; (vi) any use of cash collateral under Section 363 of the Bankruptcy Code; (vii) any defense based upon an election by Agent or any Lender, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b)(2) of the Bankruptcy Code or any successor statute; (viii) any defense based upon any borrowing or any grant of a security interest under Section 364 of the Bankruptcy Code; (ix) any right of subrogation, any right to enforce any remedy which Agent or any Lender may have against any other Borrower or any other Person and any right to participate in, or benefit from, any security now or hereafter held by Agent or any Lender for the Obligations, until the full and indefeasible payment of the Obligations in cash and the termination of the Commitments; (x) presentment, demand, protest and notice of any kind, including notice of acceptance of this Agreement and of the existence, creation or incurring of new or additional Obligations; (xi) the benefit of any statute of limitations affecting the liability of any other Borrower or other Person, enforcement of this Agreement or any other Loan Documents, the liability of the Borrower hereunder or the enforcement hereof; (xii) relief from any applicable valuation or appraisement laws; (xiii) any other action by Agent or any Lender, whether authorized by this Agreement or otherwise, or any omission by Agent or any Lender or other failure of Agent or any Lender to pursue, or delay in pursuing, any other remedy in its power; and (xiv) any and all claims and/or rights of counterclaim, recoupment, setoff or offset. Each Borrower agrees that the payment and performance of all Obligations or any part thereof or other act which tolls any statute of limitations applicable to this Agreement or

the other Loan Documents shall similarly operate to toll the statute of limitations applicable to such Borrower’s liability hereunder.

(c) It is agreed among the Borrower, Agent, and each Lender that the foregoing waivers are of the essence of the transaction contemplated by this Agreement and the other Loan Documents and that, but for the provisions of this Article 18 and such waivers, Agent and Lenders would decline to enter into this Agreement.

18.3. Benefit of Guaranty. Each Borrower agrees that the provisions of this Article 18 are for the benefit of Agent and Lenders and their successors, transferees, endorsees and assigns, and nothing herein contained shall impair, as between any other Borrower and Agent or any Lender, the obligations of such other Borrower under the Loan Documents.

18.4. Waiver of Subrogation, Etc. Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, and except as set forth in Section 18.7, the Borrower hereby expressly and irrevocably waives any and all rights at law or in equity to subrogation, reimbursement, exoneration, contribution, indemnification or set off and any and all defenses available to a surety, guarantor or accommodation co-obligor until the full and indefeasible payment in cash of the Obligations and the termination of the Commitments. Each Borrower acknowledges and agrees that this waiver is intended to benefit Agent and Lenders and shall not limit or otherwise affect such Borrower’s liability hereunder or the enforceability of this Article 18, and that Agent, Lenders, and their successors and assigns are intended third party beneficiaries of the waivers and agreements set forth in this Section 18.4.

18.5. Election of Remedies. If Agent or any Lender may, under applicable law, proceed to realize its benefits under any of the Loan Documents giving Agent or such Lender a Lien upon any Collateral, whether owned by the Borrower or by any other Person, either by judicial foreclosure or by non judicial sale or enforcement, Agent or such Lender may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of its rights and remedies under this Article 18. If, in the exercise of any of its rights and remedies, Agent or any Lender shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against the Borrower or any other Person, whether because of any applicable laws pertaining to “election of remedies” or the like, the Borrower hereby consents to such action by Agent or such Lender and waives any claim based upon such action, even if such action by Agent or such Lender shall result in a full or partial loss of any rights of subrogation that each Loan Party might otherwise have had but for such action by Agent or such Lender. Any election of remedies that results in the denial or impairment of the right of Agent or any Lender to seek a deficiency judgment against the Borrower shall not impair any other Borrower’s obligation to pay the full amount of the Obligations. In the event Agent or any Lender shall bid at any foreclosure or trustee’s sale or at any private sale permitted by law or the Loan Documents, Agent or such Lender may bid all or less than the amount of the Obligations and the amount of such bid need not be paid by Agent or such Lender but shall be credited against the Obligations. The amount of the successful bid at any such sale, whether Agent, any Lender, or any other party is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations guaranteed under this Article 18, notwithstanding that any present or future law or court decision or ruling may have the effect of reducing the amount of any deficiency claim to which Agent or such Lender might otherwise be entitled but for such bidding at any such sale.

18.6. Limitation. Notwithstanding any provision herein contained to the contrary, the Borrower’s liability under this Article 18 (which liability is in any event in addition to amounts for which such Borrower is primarily liable under this Agreement) shall be limited to an amount not to exceed as of any date of determination the greater of:

103

(a) the net amount of all Loans advanced to any other Borrower under this Agreement and then re-loaned or otherwise transferred to, or for the benefit of, such Borrower; and

(b) the amount that could be claimed by Agent and Lenders from such Borrower under this Article 18 without rendering such claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law after taking into account, among other things, such Borrower’s right of contribution and indemnification from each other Borrower under Section 18.7.

18.7. Contribution With Respect To Guaranty Obligations.

(a) To the extent that the Borrower shall make a payment under this Article 18 of all or any of the Obligations (other than Loans made to that Borrower for which it is primarily liable) (a “Guarantor Payment”) that, taking into account all other Guarantor Payments then previously or concurrently made by any other Borrower, exceeds the amount that such Borrower would otherwise have paid if the Borrower had paid the aggregate Obligations satisfied by such Guarantor Payment in the same proportion that such Borrower’s “Allocable Amount” (as defined below) (as determined immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of Borrower as determined immediately prior to the making of such Guarantor Payment, then, following indefeasible payment in full in cash of the Obligations and termination of the Commitments, such Borrower shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other Borrower for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment.

(b) As of any date of determination, the “Allocable Amount” of the Borrower shall be equal to the maximum amount of the claim that could then be recovered from such Borrower under this Article 18 without rendering such claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law.

(c) This Section 18.7 is intended only to supplement the relative rights of Borrower and nothing set forth in this Section 18.7 is intended to or shall impair the obligations of Borrower, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of this Agreement, including Section 18.1. Nothing contained in this Section 18.7 shall limit the liability of the Borrower to pay the Loans made directly or indirectly to that Borrower and accrued interest, fees and expenses with respect thereto for which such Borrower shall be primarily liable.

(d) The parties hereto acknowledge that the rights of contribution and indemnification hereunder or that may otherwise exist shall constitute assets of the Borrower to which such contribution and indemnification is owing.

(e) The rights of the contribution and indemnification hereunder or that may otherwise exist shall be exercisable upon the full and indefeasible payment of the Obligations and the termination of the Commitments.

18.8. Liability Cumulative. The liability of Borrower under this Article 18 is in addition to and shall be cumulative with all liabilities of the Borrower to Agent and Lenders under this Agreement and the

104

other Loan Documents to which such Borrower is a party or in respect of any Obligations or obligation of the other Borrower, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

18.9. Structure of Credit Facility. Each Loan Party states and acknowledges that: (i) pursuant to this Agreement, the Loan Parties desire to utilize their borrowing potential on a consolidated basis to the same extent possible if they were merged into a single corporate entity and that this Agreement reflects the establishment of credit facilities which would not otherwise be available to such Loan Party if each Loan Party were not jointly and severally liable for payment of any and all principal, interest, fees and other amounts now or hereafter payable under any of the Loan Documents; (ii) it has determined that it will benefit specifically and materially from the advances of credit contemplated by this Agreement; (iii) it is both a condition precedent to the obligations of Agent and the Lenders hereunder and a desire of each Loan Party that each Loan Party make the agreements set forth in this Article 18; and (iv) the Loan Parties have requested and bargained for the structure and terms of and security for the advances contemplated by this Agreement. Each Loan Party agrees and acknowledges that the present structure of the credit facilities detailed in this Agreement is based in part upon the financial and other information presently known to Agent and the Lenders regarding each Loan Party, the corporate structure of the Loan Parties, and the present financial condition of each Loan Party. Each Loan Party hereby agrees that Agent shall have the right, in its good faith credit judgment, to require that any or all of the following changes be made to these credit facilities: (i) restrict loans and advances between and among the Loan Parties, (ii) establish separate loan accounts for each Loan Party or for certain Loan Parties, and (iii) establish such other procedures as shall be reasonably deemed by Agent to be useful in tracking where advances are made under this Agreement and the source of payments received by Agent on such advances.

Re: Third Amended & Restated Credit Agreement, dated as of December 23, 2010, by and among USA Compression Holdings, LP, as guarantor, USA Compression Partners, LLC and USAC Leasing, LLC, as borrowers, the lenders from time to time party thereto, and JPMorgan Chase Bank, N.A., as agent.

Ladies and Gentlemen:

We have acted as special counsel to USA Compression Holdings, LP, a Texas limited partnership (“Holdings”), USA Compression Partners, LLC, a Delaware limited liability company (“USA Compression Partners”), and USAC Leasing, LLC, a Delaware limited liability company (“USAC Leasing”; together with USA Compression Partners, collectively the “Borrowers”) in connection with that certain Third Amended & Restated Credit Agreement, dated as of December 23, 2010 (the “Credit Agreement”), by and among Holdings as Guarantor, the Borrowers, the Lenders from time to time party thereto, and JPMorgan Chase Bank, N.A., a national banking association, as an LC Issuer and as Agent (in such capacity, the “Agent”), and the other Loan Documents (as defined below).

This letter is furnished pursuant to Section 4.1(f) of the Credit Agreement. Capitalized terms defined in the Credit Agreement, used herein and not otherwise defined herein, shall have the meanings given them in the Credit Agreement. As used herein, “Credit Parties” means the Borrowers and Holdings.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter, except where a specified fact confirmation procedure is stated to have been performed (in which case we have with your consent performed the stated procedure), and except where a statement is qualified as to knowledge (in which case we

have with your consent made no or limited inquiry as specified below). We have examined, among other things, the following:

a. the Credit Agreement;

b. that certain Second Amended and Restated Security Agreement, dated as of July 20, 2004, by and among USA Compression Partners and the Agent, as amended by that certain Tenth Amendment to Second Amended and Restated Credit Agreement and Joinder Agreement dated as of October 10, 2008 (the “Existing Security Agreement”);

c. that certain Pledge Agreement, dated as of October 10, 2008, by and among USA Compression Partners, Holdings and the Agent (the “Existing Pledge Agreement”);

d. that certain Omnibus Ratification and Confirmation Agreement dated as of December 23, 2010 (the “Confirmation”), by and among the Credit Parties and the Agent;

e. the Existing Security Agreement as amended by the Confirmation (the “Security Agreement”);

f. the Existing Pledge Agreement as amended by the Confirmation (the “Pledge Agreement”);

g. those certain revolving credit notes listed on Schedule B hereto, each dated as of the date hereof (the “Notes”);

h. a photocopy of the UCC-1 financing statement naming Holdings as debtor and the Agent as secured party, filed in the Office of the Secretary of State of the State of Texas (the “Texas Filing Office”) on October 7, 2008, as Document Number 080032945758, a copy of which is attached hereto as Exhibit A and incorporated herein by reference (the “Texas Financing Statement”);

i. (i) a photocopy of the UCC-1 financing statement naming USA Compression Partners as debtor and the Agent as secured party, filed in the Office of the Secretary of State of the State of Delaware (the “Delaware Filing Office”) on October 14, 2008, as Document Number 20083457833 (the “USA Compression Financing Statement”), and (ii) a photocopy of the UCC-1 financing statement naming USAC Leasing as debtor and the Agent as secured party, filed in the Delaware Filing Office on October 7, 2008, as Document Number 00000000000, copies of which are attached hereto as Exhibit A and incorporated herein by reference (collectively, the “Delaware Financing Statements” and, together with the Texas Financing Statement, collectively the “Financing Statements”);

j. a copy of the Certificate of Limited Partnership and a copy of the Agreement of Limited Partnership of Holdings (the “Texas Governing Documents”);

k. a copy of the Certificate of Formation and the Limited Liability Company Agreement of each of the Borrowers, each of which, with your consent, we have assumed is (i) a valid and binding agreement of the parties thereto, enforceable in accordance with the plain meaning of its terms, (ii) in full force and effect, and (iii) the entire agreement of the parties pertaining to the subject matter thereof (the “Delaware Governing Documents” and, together with the Texas Governing Documents, collectively the “Governing Documents”);

The documents described in subsections (a), (d), (e), (f) and (g) above are referred to herein collectively as the “Loan Documents”, and the documents described in subsections (a), (d) and (g) above are referred to herein collectively as the “Opinion Documents”. As used in this letter, the “TX UCC” shall mean the Uniform Commercial Code as now in effect in the State of Texas. As used in this letter, “Applicable UCC” shall mean the TX UCC and/or the Delaware UCC (as defined below), as applicable. For convenience, all references to specific chapters, articles, parts, sections or subsections of the Applicable UCC are made by using the corresponding citations to the analogous provisions of the Delaware UCC.

Except as otherwise stated herein, as to factual matters we have, with your consent, relied upon the foregoing, and upon oral and written statements and representations of officers and other representatives of the Credit Parties and others. We have not independently verified such factual matters.

Whenever a statement herein is qualified by “to the best of our knowledge,” or a similar phrase, it is intended to indicate that those attorneys in this firm who have rendered legal services in connection with the Loan Documents do not have current actual knowledge of the inaccuracy of any such statement. However, except as otherwise expressly indicated, we have not undertaken any independent inquiry to determine the accuracy of any such statement.

We are opining as to the effect on the subject transaction only of the federal laws of the United States, the internal laws of the State of Texas, in paragraphs 1, 2 and 4 of this letter, the Delaware Limited Liability Company Act (the “DLLCA”), and in paragraph 5(b) and 6(b) of this letter, the Delaware UCC (as defined below), and we express no opinion with respect to the applicability to the opinions expressed herein, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state. With your permission, we have based our opinions set forth in paragraph 6 exclusively upon our review of Article 9 of the Uniform Commercial Code of the State of Delaware as set forth in the CCH Secured Transactions Guide without regard to judicial interpretations thereof or any regulations promulgated thereunder or any other laws of the State of Delaware (the “Delaware UCC”).

Except as otherwise stated herein, our opinions herein are based upon our consideration of only those statutes, rules and regulations which, in our experience, are normally applicable to borrowers and guarantors in secured loan transactions. We express no opinion as to any state or federal laws or regulations applicable to the subject transactions because of the legal or regulatory status of any parties to the Loan Documents or the legal or regulatory status of any of their affiliates, and we express no opinion as to the effect of any governing law provision in any Loan Document to the extent such provision references federal law.

Subject to the foregoing and the other matters set forth herein, as of the date hereof:

1. (a) Each of the Borrowers is a limited liability company under the DLLCA with limited liability company power and authority to enter into the Opinion Documents and perform its obligations under the Loan Documents. With your consent, based solely on certificates from public officials, we confirm that each of the Borrowers is validly existing and in good standing under the laws of the State of Delaware.

(b) Holdings is a limited partnership under the Texas Business Organizations Code, with limited partnership power and authority to enter into the Opinion Documents and perform its obligations under the Loan Documents. With your consent, based solely on certificates from public officials, we confirm that Holdings is validly existing and in good standing under the laws of the State of Texas.

2. The execution and delivery of the Opinion Documents and the performance of the Loan Documents by each Credit Party party thereto have been duly authorized by all necessary limited partnership or limited liability company action, as applicable, of each Credit Party party thereto, and each of the Opinion Documents has been duly executed and delivered by each Credit Party party thereto.

3. Each of the Opinion Documents constitutes a legally valid and binding obligation of each of the Credit Parties party thereto, enforceable against each Credit Party party thereto in accordance with its terms.

4. The execution and delivery of the Opinion Documents by the Credit Parties, and the consummation and continued performance by the Credit Parties of the transactions contemplated by the Loan Documents, do not on the date hereof:

(i) violate the provisions of the Governing Documents;

(ii) violate any federal or Texas statute, rule, or regulation applicable to the Credit Parties (including, without limitation, Regulations T, U or X of the Board of Governors of the Federal Reserve System, assuming the Borrowers comply with the provisions of the Loan Documents relating to the use of proceeds), or, with respect to the Borrowers, the DLLCA; or

(iii) require any consents, approvals, or authorizations to be obtained by any Credit Party from, or any registrations, declarations or filings to be made by such Credit Party with, any governmental authority under any federal or Texas statute, rule or regulation applicable to such Credit Party or, with respect to the Borrowers, the DLLCA, if applicable, except (a) filings and recordings required in order to perfect or otherwise protect the security interests under the Loan Documents.

5. (a) The Confirmation does not, of itself, adversely affect the validity under the TX UCC of the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in that part of the collateral described in Article II of the Security Agreement in which any Credit Party has rights in which a valid security interest may be created under Article 9

of the TX UCC (the “UCC Collateral”), and after giving effect to the Confirmation, the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in the UCC Collateral will be a valid security interest under Article 9 of the TX UCC to the same extent that it was a valid security interest immediately before the effectiveness of the Confirmation.

(b) The Confirmation does not, of itself, adversely affect the validity under the TX UCC of the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in that part of the collateral described in Article II of the Pledge Agreement in which either of USA Compression and Holdings has rights in which a valid security interest may be created under Article 9 of the TX UCC (the “Pledged Collateral”, and, together with the UCC Collateral, the “Collateral”), and after giving effect to the Confirmation, the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in the Pledged Collateral will be a valid security interest under Article 9 of the TX UCC to the same extent that it was a valid security interest immediately before the effectiveness of the Confirmation

6. (a) The Confirmation does not, of itself, adversely affect perfection of the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, under the TX UCC in that part of the Collateral in which, immediately before the effectiveness of the Confirmation, the Agent, on behalf of and for the ratable benefit of the Lenders, had a perfected security interest solely by virtue of the filing of the Texas Financing Statement in the Texas Filing Office (the “Texas Filing Collateral”) and after giving effect to the Confirmation, the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in such Texas Filing Collateral will be a perfected security interest under Article 9 of the TX UCC to the same extent that it was a perfected security interest immediately before the effectiveness of the Confirmation.

(b) The Confirmation does not, of itself, adversely affect perfection of the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, under the Delaware UCC in that part of the Collateral in which, immediately before the effectiveness of the Confirmation, the Agent, on behalf of and for the ratable benefit of the Lenders, had a perfected security interest solely by virtue of the filing of the Delaware Financing Statement in the Delaware Filing Office (the “Delaware Filing Collateral”) and after giving effect to the Confirmation, the security interest of the Agent, on behalf of and for the ratable benefit of the Lenders, in such Delaware Filing Collateral will be a perfected security interest under Article 9 of the Delaware UCC to the same extent that it was a perfected security interest immediately before the effectiveness of the Confirmation.

7. No Borrower is required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Except as expressly set forth in paragraph 5 and 6, we do not express any opinion with respect to the creation, validity, attachment, perfection or priority of any security interest or lien or the effectiveness of any sale or other conveyance or transfer of real or personal property. The opinions above do not include any opinions with respect to compliance with laws relating to permissible rates of interest.

Our opinions are subject to:

(a) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights or remedies of creditors, and the judicial application of foreign laws or governmental actions affecting creditors’ rights;

(b) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith, fair dealing and the discretion of the court before which a proceeding is brought;

(c) the invalidity under certain circumstances under law or court decisions of provisions for the indemnification or exculpation of or contribution to a party with respect to a liability where such indemnification, exculpation or contribution is contrary to public policy; and

(d) we express no opinion with respect to (i) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies or judicial relief; (ii) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights; (iii) waivers of broadly or vaguely stated rights; (iv) covenants not to compete; (v) provisions for exclusivity, election or cumulation of rights or remedies; (vi) provisions authorizing or validating conclusive or discretionary determinations; (vii) grants of setoff rights; (viii) provisions to the effect that a guarantor is liable as a primary obligor, and not as a surety and provisions purporting to waive modifications of any guaranteed obligation to the extent such modification constitutes a novation; (ix) provisions for the payment of attorneys’ fees where such payment is contrary to law or public policy; (x) proxies, powers and trusts; (xi) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property; (xii) provisions for liquidated damages, default interest, late charges, monetary penalties, prepayment or make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty; (xiii) provisions permitting, upon acceleration of any indebtedness, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon; and (xiv) the severability, if invalid, of provisions to the foregoing effect.

(e) We have assumed that since October 10, 2008, neither the Security Agreement nor the Pledge Agreement has been amended, restated, modified, supplemented, or terminated and that no rights pursuant thereto have been released, waived, or modified either expressly or by any action or inaction of the parties thereto, other than pursuant to the Credit Agreement or the Confirmation.

(f) We have assumed that since October 14, 2008, the USA Compression Financing Statement has not been amended, restated, modified, supplemented, or terminated and that no rights pursuant thereto have been released, waived, or modified either expressly or by any action or inaction of the parties thereto, other than pursuant to the Credit Agreement or the Confirmation

(g) We have assumed that since October 7, 2008, the Financing Statements (other than the USA Compression Financing Statement) have not been amended, restated, modified, supplemented, or terminated and that no rights pursuant thereto have been released, waived, or modified either expressly or by any action or inaction of the parties thereto, other than pursuant to the Credit Agreement or the Confirmation

(h) We have assumed that each of the Existing Security Agreement and the Existing Pledge Agreement is the legally valid and binding obligation of each party thereto and is enforceable against each such party in accordance with its terms.

We express no opinion or confirmation as to federal or state securities laws (except as set forth in paragraph 7 of this letter), tax laws, antitrust or trade regulation laws, insolvency or fraudulent transfer laws, antifraud laws, compliance with fiduciary duty requirements, pension or employee benefit laws, usury laws, environmental laws, margin regulations (except as set forth in paragraph 4(ii) of this letter), FINRA rules or stock exchange rules (without limiting other laws excluded by customary practice).

We express no opinion as to the validity, binding effect or enforceability of the following provisions to the extent such provisions are included in the Loan Documents: (a) provisions entitling a purchaser at a foreclosure sale to affirm or disaffirm leases without regard to the priority of such leases as to the lien foreclosed; (b) provisions relating to self-help (other than non-judicial foreclosure), marshalling of assets, the transferability of assets which by law or agreement are not transferable or severance clauses; (c) exculpation clauses and release clauses (1) that release or exculpate a party from liability in connection with violations of any securities laws or other laws or statutory duties or public policy, or in connection with willful misconduct, reckless or unlawful acts or negligence, strict liability or bad faith of the released or exculpated party, (2) that shift risk in an extraordinary way, or (3) that a court would determine to be insufficiently explicit or conspicuous; (d) provisions limiting the ability of any Credit Party to transfer or encumber, voluntarily or involuntarily, any right, title or interest in or to any property or assets (of any kind) subject thereto (and this opinion is specifically made subject to Section 9-401 of the Applicable UCC), but in our view such limitations do not render unenforceable any provisions of the Loan Documents which provide that a transfer in violation thereof constitutes a default thereunder; (e) provisions entitling any party to the appointment of a receiver, to the extent contrary to applicable law; (f) provisions purporting to permit the Lender or any other person acting on behalf of the Lender to purchase, sell or otherwise dispose of any property subject thereto except in compliance with applicable law; (g) provisions purporting to provide standards for the care of property or assets (of any kind) in possession of any person other than as provided by applicable law; (h) provisions purporting to irrevocably appoint any person as attorney in fact for the Credit Parties; (i) provisions limiting the application of Sections 43.001 through 43.005 of the Texas Civil Practices and Remedies Code; (j) provisions waiving implied covenants other than as provided by applicable law; (k) provisions purporting to secure future advances to the Borrowers other than those currently contemplated by the parties as of the date hereof; (l) provisions permitting a creditor to treat any collateral as if the creditor owned it prior to foreclosure, including, without limitation, by the prosecution, defense, compromise or settlement of claims, by the exercise of voting or consent rights, or by the use of such collateral, or release a creditor from liability in connection with any such action; (m) that is a usury savings clause; and

(n) provisions establishing evidentiary standards for suits or proceedings to enforce the Loan Documents.

The opinions set forth above are also subject to (i) the unenforceability of contractual provisions waiving or varying the rules listed in Section 9-602 of the TX UCC, (ii) the unenforceability under certain circumstances of contractual provisions respecting self-help or summary remedies without notice of or opportunity for hearing or correction, (iii) the effect of provisions of the TX UCC and other general legal principles that impose a duty to act in good faith and in a commercially reasonable manner, and (iv) the effect of Sections 9-406, 9-407, 9-408 and 9-409 of the TX UCC on any provision of any Loan Document that purports to prohibit, restrict, require consent for or otherwise condition the assignment of rights under such Loan Document.

Our opinions in paragraphs 5 and 6(a) above are limited to Article 9 of the TX UCC, and our opinions in paragraph 6(b) above are limited to Article 9 of the Delaware UCC, and therefore those opinion paragraphs, among other things, do not address collateral of a type not subject to, or excluded from the coverage of, Article 9 of the TX UCC or Article 9 of the Delaware UCC, as applicable. Additionally,

(i) We express no opinion with respect to the priority of any security interest or lien.

(ii) We express no opinion with respect to any agricultural lien or any collateral that consists of letter-of-credit rights, commercial tort claims, goods covered by a certificate of title, claims against any government or governmental agency, consumer goods, crops growing or to be grown, timber to be cut, goods which are or are to become fixtures, as-extracted collateral, or cooperative interests.

(iii) We assume the descriptions of collateral contained in, or attached as schedules to, the Loan Documents and any financing statements accurately and sufficiently describe the collateral intended to be covered by the Loan Documents or such financing statements. Additionally, we express no opinion as to whether the phrases “all personal property” or “all assets” or similarly general phrases would be sufficient to create a valid security interest in the collateral or particular item or items of collateral; however, we note that pursuant to Section 9-504 of the Delaware UCC the phrases “all assets” or “all personal property” can be a sufficient description of collateral for purposes of perfection by the filing of a financing statement

(iv) We have assumed that each grantor of any security interests has, or with respect to after-acquired property will have, rights in the collateral granted by it or the power to transfer rights in such collateral, and that each such grantor has received value, and we express no opinion as to the nature or extent of the any grantor’s rights in any of the collateral and we note that with respect to any after-acquired property, the security interest will not attach until the applicable grantor acquires such rights or power.

(v) We call to your attention the fact that the perfection of a security interest in “proceeds” (as defined in the Applicable UCC) of collateral is governed and restricted by Section 9-315 of the Applicable UCC.

(vi) We have assumed that the exact legal name of each of the Credit Parties is as set forth in the copy of the organizational documents certified by the Delaware Secretary of State or Texas Secretary of State, as applicable, and we have also assumed the accuracy of the other factual information set forth on the Financing Statements.

(vii) Section 552 of the federal Bankruptcy Code limits the extent to which property acquired by a debtor after the commencement of a case under the federal Bankruptcy Code may be subject to a security interest arising from a security agreement entered into by the debtor before the commencement of such case.

(viii) We express no opinion with respect to any property subject to a statute, regulation or treaty of the United States whose requirements for a security interest’s obtaining priority over the rights of a lien creditor with respect to the property preempt Section 9-310(a) of the Applicable UCC.

(ix) We express no opinion with respect to any goods which are accessions to, or commingled or processed with, other goods to the extent that the security interest is limited by Section 9-335 or 9-336 of the Applicable UCC.

(x) We call to your attention that a security interest may not attach or become enforceable or be perfected as to contracts, licenses, permits, equity interests or other property which are not assignable under applicable law, or are subject to consent requirements or contractual or other prohibitions or restrictions on assignment, except to the extent that any such prohibitions, restrictions or consent requirements may be rendered ineffective to prevent the attachment of the security interest pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the Applicable UCC; and we note that the extent of any security interest created in reliance on such UCC provisions may be limited. In addition, we call to your attention that your rights under the Loan Documents as secured parties may be subject to the provisions of the organizational and governing documents of any entity in which any equity interests (or other rights of equity holders or investors) are pledged and the provisions of the applicable laws under which any such entity is organized.

(xi) We express no opinion regarding any security interest in any copyrights, patents, trademarks, service marks or other intellectual property, or any license or sublicense thereof or the proceeds of any of the foregoing except to the extent Article 9 of the Applicable UCC, may be applicable to the foregoing and, without limiting the generality of the foregoing, we express no opinion as to the effect of any federal laws relating to copyrights, patents, trademarks, service marks or other intellectual property on the opinions expressed herein. In addition, we call to your attention that any license or sublicense of copyrights, patents, trademarks or other intellectual property may not be assignable unless such license or sublicense affirmatively permits the creation, perfection and enforcement of a security interest therein.

(xii) We express no opinion as to the priority of the security interest as against any lien creditor to the extent that such security interest purports to secure any advances or other obligations other than those that are made without knowledge of the lien or pursuant to a commitment entered into without knowledge of the liens.

(xiii) We have assumed, with respect to the security interest of the Agent for the benefit of the Secured Parties, that the Agent has been duly appointed as agent for such persons.

With your consent, we have assumed (a) that each of the Loan Documents has been duly authorized, executed and delivered by the parties thereto (other than, with respect to the Opinion Documents, the Credit Parties), (b) that the Loan Documents constitute legally valid and binding obligations of the parties thereto (other than, with respect to the Opinion Documents, the Credit Parties), enforceable against each of them in accordance with their respective terms, and (c) that the status of the Loan Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities, provided that we make no such assumptions to the extent we have opined as to such matters with respect to the Credit Parties herein. This letter is furnished only to you and is solely for your benefit in connection with the transactions referenced in the first paragraph. This letter may not be relied upon by you for any other purpose, or furnished to, assigned to, quoted to or relied upon by any other person, firm or entity for any purpose, without our prior written consent, which may be granted or withheld in our discretion. At your request, we hereby consent to reliance hereon by any future assignee of your interest in the loans under the Credit Agreement pursuant to an assignment that is made and consented to in accordance with the express provisions of Section 12.3 of the Credit Agreement, on the condition and understanding that (i) this letter speaks only as of the date hereof, (ii) we have no responsibility or obligation to update this letter, to consider its applicability or correctness to other than its addressee(s), or to take into account changes in law, facts or any other developments of which we may later become aware, and (iii) any such reliance by a future assignee must be actual and reasonable under the circumstances existing at the time of assignment, including any changes in law, facts or any other developments known to or reasonably knowable by the assignee at such time.
