(vi) If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.14(c) by the time specified in Section 2.14(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the Federal Funds Rate from time to time in effect.

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

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

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

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

percent shareholder” of the Borrower within the meaning of section 88l(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN; or

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

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

3.02 Illegality. If any Lender determines that any Change in Law has made it unlawful for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or materially restricts the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period thereof, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay interest on the amount so prepaid or converted and all amounts due under Section 3.05 in accordance with the terms thereof due to such prepayment or conversion. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the reasonable judgment of such Lender, otherwise be materially disadvantageous to such Lender.

3.03 Inability to Determine Rates. If the Administrative Agent determines in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the applicable offshore Dollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, or adequate and reasonable means do not exist for determining the Eurodollar Rate for such Eurodollar Rate Loan, or (b) if the Required Lenders determine

Credit Agreement

and notify the Administrative Agent that the Eurodollar Rate for such Eurodollar Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such Eurodollar Rate Loan, then the Administrative Agent will promptly notify the Borrower and all Lenders. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing, conversion or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

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

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

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

(c) The Borrower shall pay to each Lender, as long as such Lender shall be required under regulations of the Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional costs on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves, allocated to such Revolving Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Revolving Loan; provided the Borrower shall have received at least 15 days’ prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give notice 15 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 15 days from receipt of such notice.

(d) Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to

Quest Resource
Credit Agreement

the date that such Lender or the L/C Issuer, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the L/C Issuer’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

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

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

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

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

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

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

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

Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent or Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

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

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

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Commitment and/or the Revolving Loans (including such Lender’s participation in L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that would (i) postpone any date upon which any payment of money is scheduled to be paid to such Participant, (ii) reduce the principal, interest, fees or other amounts payable to such Participant, or (iii) release any Guarantor from its Guaranty. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section; provided said Participant agrees to be subject to Sections 3.08 and 10.15 as though it were a Lender. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.09 as though it were a Lender; provided such Participant agrees to be subject to Section 2.12 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s

Quest Resource
Credit Agreement

prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01 as though it were a Lender.

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

(g) If the consent of the Borrower to an assignment or to an Eligible Assignee is required hereunder (including a consent to an assignment which does not meet the minimum assignment threshold specified in clause (i) of the proviso to the first sentence of Section 10.07(b)), the Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth Business Day.

(h) Notwithstanding anything to the contrary contained herein, if at any time Royal Bank of Canada assigns all of its Revolving Commitment and Revolving Loans pursuant to subsection (b) above, Royal Bank of Canada may, upon 30 days’ notice to the Borrower and the Lenders, resign as L/C Issuer. In the event of any such resignation as L/C Issuer, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Royal Bank of Canada as L/C Issuer. Royal Bank of Canada shall retain all the rights and obligations of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund participations in Unreimbursed Amounts pursuant to Section 2.14(c)).

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

Quest Resource
Credit Agreement

such disclosure is made will be informed of the confidential nature of such information and obligated to keep such information confidential).

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

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

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

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

Quest Resource
Credit Agreement

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

10.14 Severability. Any provision of this Agreement and the other Loan Documents to which the Borrower is a party that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

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

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

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Revolving Loans, L/C Advances, L/C Borrowings, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) such payment being at par, with no premium or discount;

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

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

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

10.16 Governing Law.
