GUARANTY PROVISIONS

     SECTION 2.1 Guaranty. Each Guarantor hereby absolutely, unconditionally, and irrevocably (1) guarantees the full and punctual payment when due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise, of all Obligations of the Borrowers and each other Obligor now or hereafter existing under each of the Credit Agreement, the Notes and each other Loan Document to which the Borrowers or such other Obligor is or may become a party, whether for principal, interest, fees, expenses or otherwise (including all such amounts which would become due but for the operation of the automatic stay under Section 362(a) of the United States Bankruptcy Code, 11 U.S.C. §362(a), and the operation of Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C. §502(b) and §506(b)), and (2) indemnifies and holds harmless each Lender and each holder of a Note for any and all costs and expenses (including reasonable attorney’s fees and expenses) incurred by such Lender or such holder, as the case may be, in enforcing any rights under this Guaranty; provided however, that each Guarantor shall be liable under this Guaranty for the maximum amount of such liability that can be hereby incurred without rendering this Guaranty, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount. This Guaranty constitutes a guaranty of payment when due and not of collection, and each Guarantor specifically agrees that it shall not be necessary or required that any Lender or any holder of any Note exercise any right, assert any claim or demand or enforce any remedy whatsoever against the Borrowers or any other Obligor (or any other Person) before or as a condition to the obligations of such Guarantor hereunder.

     SECTION 2.2 Acceleration of Guaranty. Each Guarantor agrees that, in the event of the occurrence of any event of the type described in Section 8.01(f) of the Credit Agreement, with respect to the Borrowers, any other Obligor or any other Guarantor, and if such event shall occur at a time when any of the Obligations may not then be due and payable, such Guarantor will pay to the Lenders forthwith the full amount which would be payable hereunder by such Guarantor if all such Obligations were then due and payable.

     SECTION 2.3 Guaranty Absolute, etc. This Guaranty shall in all respects be a continuing, absolute, unconditional and irrevocable guaranty of payment, and shall remain in full force and effect until all Obligations (other than contingent indemnity obligations) of the Borrowers and each other Obligor have been paid in full (or, in the case of L/C Obligations, Cash Collateralized), all obligations of the Guarantors hereunder shall have been paid in full, all Commitments shall have terminated and, except as provided in Section 10.01(e) of the Credit Agreement, all Lender Hedging Agreements have terminated. No Guarantor may rescind or revoke its obligations hereunder. Each Guarantor guarantees that the Obligations of the Borrowers and each other Obligor will be paid strictly in accordance with the terms of the Credit Agreement and each other Loan Document under which they arise, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Lender or any holder of any Note with respect thereto. The liability of each Guarantor under this Guaranty shall be absolute, unconditional and irrevocable irrespective of: (1) any lack of validity, legality or enforceability of the Credit Agreement, any Note or any other Loan Document; (2) the failure of any Lender or any holder of any Note (a) to assert any claim or demand or to enforce any right or remedy against the Borrowers, any other Obligor or any other Person (including any other guarantor)

		Post-Recombination Parent and Quest Parent 1st Lien Energy Guaranty

under the provisions of the Credit Agreement, any Note, any other Loan Document or otherwise, or (b) to exercise any right or remedy against any other guarantor of, or collateral securing, any Obligations of the Borrowers or any other Obligor; (3) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations of the Borrowers or any other Obligor, or any other extension, compromise or renewal of any Obligations of the Borrowers or any other Obligor; (4) any reduction, limitation, impairment or termination of any Obligations of the Borrowers or any other Obligor for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and each Guarantor hereby waives any right to or claim of) any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Obligations of the Borrowers, any other Obligor or otherwise; (5) any amendment to, rescission, waiver, or other modification of, or any consent to departure from, any of the terms of the Credit Agreement, any Note or any other Loan Document; (6) any addition, exchange, release, surrender or non-perfection of any collateral, or any amendment to or waiver or release or addition of, or consent to departure from, any other guaranty, held by any Lender or any holder of any Note securing any of the Obligations of the Borrowers or any other Obligor; (7) the insolvency or bankruptcy of, or similar event affecting, the Borrowers or any other Obligor; or (8) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, the Borrowers, any other Obligor, any surety or any guarantor. Each Guarantor waives all rights and defenses which may arise with respect to any of the foregoing, and each Guarantor waives any right to revoke this Guaranty with respect to future indebtedness.

     SECTION 2.4 Reinstatement. Each Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part) of any of the Obligations is rescinded or must otherwise be restored by any Lender or any holder of any Note, upon the insolvency, bankruptcy or reorganization of either Borrower, any other Obligor or otherwise, all as though such payment had not been made.

     SECTION 2.5 Waiver, etc. The Guarantors hereby waive promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations of the Borrowers or any other Obligor and this Guaranty and any requirement that the Administrative Agent, any other Lender or any holder of any Note protect, secure, perfect or insure any security interest or Lien, or any property subject thereto, or exhaust any right or take any action against the Borrowers, any other Obligor or any other Person (including any other guarantor) or entity or any collateral securing the Obligations of the Borrowers or any other Obligor, as the case may be.

     SECTION 2.6 Waiver of Subrogation. Until the Obligations are paid in full, all Commitments have terminated and all Lender Hedging Agreements have terminated (except as provided in Section 10.01(e) of the Credit Agreement), the Guarantors shall not enforce or exercise any claim or other rights which they may now or hereafter acquire against the Borrowers or any other Obligor that arise from the existence, payment, performance or enforcement of any Guarantor’s obligations under this Guaranty or any other Loan Document, including any right of subrogation, reimbursement, exoneration, or indemnification, any right to participate in any claim or remedy of the Lenders against the Borrowers or any other Obligor or any collateral which the Administrative Agent now has or hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from the Borrowers or any other Obligor, directly or indirectly, in cash or other property or by set-off or in any manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence, such amount shall be deemed to have been paid to such Guarantor for the benefit of, and held in trust for, the

		Post-Recombination Parent and Quest Parent 1st Lien Energy Guaranty

Lenders, and shall forthwith be paid to the Administrative Agent for the benefit of the Lenders by the Guarantor receiving such payment to be credited and applied upon the Obligations, whether matured or unmatured. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreement and that the waiver set forth in this Section is knowingly made in contemplation of such benefits.

     SECTION 2.7 Payments Free and Clear of Taxes, etc. Each Guarantor hereby agrees that:

     (a) All payments by such Guarantor hereunder shall be made in accordance with Section 3.01 of the Credit Agreement free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto; excluding, in the case of the Administrative Agent and each Lender, taxes imposed on or measured by its net income (including any franchise taxes imposed on or measured by its net income), by the jurisdiction (or any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender, as the case may be, is organized or maintains its Lending Office (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). In the event that any withholding or deduction from any payment to be made by such Guarantor hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then such Guarantor will (i) pay directly to the relevant authority the full amount required to be so withheld or deducted; (ii) promptly forward to such Lender an official receipt or other documentation satisfactory to such Lender evidencing such payment to such authority; and (iii) pay to such Lender such additional amount or amounts as is necessary to ensure that the net amount actually received by such Lender will equal the full amount such Lender would have received had no such withholding or deduction been required. Moreover, if any Taxes are directly asserted against any Lender with respect to any payment received by such Lender hereunder, such Lender may pay such Taxes and such Guarantor will promptly pay such additional amounts (including, if incurred as a result of such Guarantor’s or the Borrower’s action, omission or delay, any penalties, interest or expenses) as is necessary in order that the net amount received by such Lender after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount such Lender would have received had such Taxes not been asserted.

     (b) If a Guarantor fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to any Lender the required receipts or other required documentary evidence, such Guarantor shall indemnify such Lender for any incremental Taxes, interest or penalties that may become payable by such Lender as a result of any such failure.

     (c) Without prejudice to the survival of any other agreement of the Guarantors hereunder, the agreements and obligations of the Guarantors contained in this Section 2.7 shall survive the payment in full of the principal of and interest on the Revolving Loan.

     SECTION 2.8 Subordination. Each Guarantor hereby subordinates and makes inferior to the Obligations any and all indebtedness now or at any time hereafter owed by the Borrowers or other Obligor to such Guarantor. Each Guarantor agrees that if any Event of Default has occurred and is continuing under the Credit Agreement, it will not permit the Borrowers to repay such indebtedness or any part thereof and it will not accept payment from the Borrowers of such indebtedness or any part thereof without the prior written consent of the Required Lenders. If a Guarantor receives any such payment without the prior required written consent, the amount so paid shall be held in trust for the benefit of the Lenders, shall be segregated from the other funds of such Guarantor, and shall forthwith be paid over to the Administrative Agent to be held by the Administrative Agent as collateral for, or then or

		Post-Recombination Parent and Quest Parent 1st Lien Energy Guaranty

at any time thereafter applied in whole or in part by the Administrative Agent against, all or any portions of the Obligations, whether matured or unmatured, in such order as the Administrative Agent shall elect.

However, the Guarantors are not required to inquire about any such agreement and are not subject to any terms of it unless the Guarantors specifically enter into such agreement. Therefore, neither Guarantors nor any of their successors or assigns are entitled to any benefits or provisions of any such separate agreement nor are they entitled to rely upon or raise as a defense any party’s failure or refusal to comply with the provisions of any such agreement.

     (b) This Guaranty benefits the Administrative Agent, the Lenders, and their respective successors and assigns and binds each Guarantor and its successors and assigns.

The Credit Agreement contains provisions governing assignments of the obligations guaranteed under this Guaranty.
