(b) All reasonable costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Administrative Agent in connection with any suit or proceeding in connection with the performance by the Administrative Agent of any of the agreements contained in any of the Contract Documents, or in connection with any exercise of its rights or remedies hereunder, pursuant to the terms of this Security Agreement, shall constitute additional indebtedness secured by this Security Agreement and shall be paid on demand by the Grantors to the Administrative Agent on behalf of the Secured Parties.

Section 8. Remedies Cumulative; Delay Not Waiver.

(a) No right, power or remedy herein conferred upon or reserved to the Administrative Agent is intended to be exclusive of any other right, power or remedy and every such right, power and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right, power and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder or otherwise shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Resort to any or all security now or hereafter held by the Administrative Agent may be taken concurrently or successively and in one or several consolidated or independent judicial actions or lawfully taken nonjudicial proceedings, or both.

(b) No delay or omission of the Administrative Agent to exercise any right or power accruing upon the occurrence and during the continuance of any Event of Default as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and every power and remedy given by this Security Agreement may be exercised from time to time, and as often as shall be deemed expedient, by the Administrative Agent.

Section 9. Contract Rights. After the occurrence and during the continuance of an Event of Default, the Administrative Agent may exercise any of the Contract Rights and remedies of any Grantor under or in connection with the Instruments, Chattel Paper, or Contracts which represent Accounts, the General Intangibles, or which otherwise relate to the Collateral, including, without limitation, any rights of any Grantor to demand or otherwise require payment of any amount under, or performance of any provisions of, the Instruments, Chattel Paper, or Contracts which represent Accounts, or the General Intangibles.

Section 10. Accounts.

(a) After the occurrence and during the continuance of an Event of Default, the Administrative Agent may, or may direct any Grantor to, take any action the Administrative Agent deems necessary or advisable to enforce collection of the Accounts, including, without limitation, notifying the account debtors or obligors under any Accounts of the assignment of such Accounts to the Administrative Agent and directing such account debtors or obligors to make payment of all amounts due or to become due directly to the Administrative Agent. Upon such notification and direction, and at the expense of the Grantors, the Administrative Agent may enforce collection of any such Accounts, and adjust, settle, or compromise the amount or payment thereof in the same manner and to the same extent as any Grantor might have done.

(b) After receipt by any Grantor of the notice referred to in Section 10(a) above that an Event of Default has occurred and is continuing, all amounts and Proceeds (including instruments) received by such Grantor in respect of the Accounts shall be received in trust for the benefit of the Administrative Agent hereunder, shall be segregated from other funds of such Grantor, and shall promptly be paid over to the Administrative Agent in the same form as so received (with any necessary indorsement) to be held as Collateral. No Grantor shall adjust, settle, or compromise the amount or payment of any Account, nor release wholly or partly any account debtor or obligor thereof, nor allow any credit or discount thereon other than in the ordinary course of business and consistent with past practices.

Section 11. Application of Collateral. The proceeds of any sale, or other realization (other than that received from a sale or other realization permitted by the Credit Agreement) upon all or any part of the Collateral pledged by any Grantor shall be applied by the Administrative Agent as set forth in Section 7.06 of the Credit Agreement.

Section 12. Administrative Agent as Attorney-in-Fact for Grantor. Each Grantor hereby constitutes and irrevocably appoints the Administrative Agent, acting for and on behalf of itself and the Secured Parties and each successor or assign of the Administrative Agent and the Secured Parties, the true and lawful attorney-in-fact of such Grantor, with full power and authority in the place and stead of such Grantor and in the name of such Grantor, the Administrative Agent or otherwise to, following the occurrence and during the continuation of an Event of Default, take any action and execute any instrument at the written direction of the Secured Parties and enforce all rights, interests and remedies of such Grantor with respect to the Collateral, including the right:

(a) to ask, require, demand, receive and give acquittance for any and all moneys and claims for moneys due and to become due under or arising out of the any of the other Collateral, including without limitation, any Insurance Contracts;

(b) to elect remedies thereunder and to endorse any checks or other instruments or orders in connection therewith;

(c) to file any claims or take any action or institute any proceedings in connection therewith which the Administrative Agent may deem to be necessary or advisable;

(d) to pay, settle or compromise all bills and claims which may be or become liens or security interests against any or all of the Collateral, or any part thereof, unless a bond or other security satisfactory to the Administrative Agent has been provided; and

(e) upon foreclosure, to do any and every act which any Grantor may do on its behalf with respect to the Collateral or any part thereof and to exercise any or all of such Grantor’s rights and remedies under any or all of the Collateral;

provided, however, that the Administrative Agent shall not exercise any such rights except upon the occurrence and continuation of an Event of Default. This power of attorney is a power coupled with an interest and shall be irrevocable.

Section 13. Administrative Agent May Perform. The Administrative Agent may from time-to-time perform any act which any Grantor has agreed hereunder to perform and which such Grantor shall fail to perform after being requested in writing so to perform (it being understood that no such request need be given after the occurrence and during the continuance of any Event of Default and after notice thereof by the Administrative Agent to any Grantor) and the Administrative Agent may from time-to-time take any other action which the Administrative Agent deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein, and the reasonable expenses of the Administrative Agent incurred in connection therewith shall be part of the Secured Obligations and shall be secured hereby.

Section 14. Administrative Agent Has No Duty. The powers conferred on the Administrative Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Administrative Agent shall have no duty as to any Collateral or responsibility for taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

Section 15. Reasonable Care. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Administrative Agent accords its own Property.

Section 16. Payments Held in Trust. During the continuance of an Event of Default, all payments received by any Grantor under or in connection with any Collateral shall be received in trust for the benefit of the Administrative Agent, and shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Administrative Agent in the same form as received (with any necessary endorsement).

Section 17. Miscellaneous.

(a) Expenses. Each Grantor will upon demand pay to the Administrative Agent for its benefit and the benefit of the Secured Parties the amount of any reasonable out-of-pocket expenses, including the reasonable fees and disbursements of its counsel and of any experts, which the Administrative Agent and the Secured Parties may incur in connection with (i) the

custody, preservation, use, or operation of, or the sale, collection, or other realization of, any of the Collateral, (ii) the exercise or enforcement of any of the rights of the Administrative Agent or any Secured Party hereunder, and (iii) the failure by any Grantor to perform or observe any of the provisions hereof.

(b) Amendments; Etc. No amendment or waiver of any provision of this Security Agreement nor consent to any departure by any Grantor herefrom shall be effective unless the same shall be in writing and executed by the affected Grantor and the Administrative Agent (acting upon the written direction of the Majority Lenders), and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

(c) Addresses for Notices. All notices and other communications provided for hereunder shall be made in the manner and to the addresses set forth in the Credit Agreement.

(d) Continuing Security Interest; Transfer of Interest. This Security Agreement shall create a continuing security interest in the Collateral and, unless expressly released by the Administrative Agent, shall (a) remain in full force and effect until the indefeasible payment in full in cash of the Secured Obligations (including all Letter of Credit Obligations), the termination or expiration of all Letters of Credit and the termination of all obligations of the Issuing Lender and the Lenders in respect of Letters of Credit, the termination of the Hedge Contracts with the Secured Parties and the termination or expiration of the Commitments, (b) be binding upon each Grantor and its successors, tranferees and assigns, and (c) inure, together with the rights and remedies of the Administrative Agent hereunder, to the benefit of and be binding upon, the Administrative Agent, the Issuing Lender, the Lenders, and their respective successors, transferees, and assigns, and to the benefit of and be binding upon, the Swap Counterparties, and each of their respective successors, transferees, and assigns to the extent such successors, transferees, and assigns of a Swap Counterparty is a Lender or an Affiliate of a Lender. Without limiting the generality of the foregoing clause, when any Lender assigns or otherwise transfers any interest held by it under the Credit Agreement or other Loan Documents to any other Person pursuant to the terms of the Credit Agreement or such other Loan Documents, that other Person shall thereupon become vested with all the benefits held by such Lender under this Security Agreement. Notwithstanding the foregoing, when any Swap Counterparty assigns or otherwise transfers any interest held by it under any Hedge Contract to any other Person pursuant to the terms of such agreement, that other Person shall thereupon become vested with all the benefits held by such Secured Party under this Security Agreement only if such Person is also then a Lender or an Affiliate of a Lender.

(e) Severability. Wherever possible each provision of this Security Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Security Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Security Agreement.

(f) Choice of Law. This Security Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Texas, except to the extent that the validity or perfection of the security interests hereunder, or remedies hereunder, in respect of any particular Collateral are governed by the laws of a jurisdiction other than the state of Texas.

(g) Counterparts. The parties may execute this Security Agreement in counterparts, each of which constitutes an original, and all of which, collectively, constitute only one agreement. Delivery of an executed counterpart signature page by facsimile is as effective as executing and delivering this Security Agreement in the presence of the other parties to this Security Agreement. In proving this Security Agreement, a party must produce or account only for the executed counterpart of the party to be charged.

(h) Headings. Paragraph headings have been inserted in this Security Agreement as a matter of convenience for reference only and it is agreed that such paragraph headings are not a part of this Security Agreement and shall not be used in the interpretation of any provision of this Security Agreement.

(i) Conflicts. In the event of any explicit or implicit conflict between any provision of this Security Agreement and any provision of the Credit Agreement, the terms of the Credit Agreement shall be controlling.

(j) Additional Grantors. Pursuant to Section 6.15 of the Credit Agreement, each Subsidiary of the Borrower that was not in existence on the date of the Credit Agreement is required to enter into this Security Agreement as a Grantor upon becoming a Subsidiary of the Borrower. Upon execution and delivery after the date hereof by the Administrative Agent and such Subsidiary of an instrument in the form of Annex 1, such Subsidiary shall become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of any instrument adding an additional Grantor as a party to this Security Agreement shall not require the consent of any other Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Security Agreement.

(k) Amendment and Restatement; Confirmation of Liens. This Security Agreement is an amendment and restatement of the Existing Security Agreement and supersedes the Existing Security Agreement in its entirety; provided, however, that (i) the execution and delivery of this Security Agreement shall not effect a novation of the Existing Security Agreement but shall be, to the fullest extent applicable, in modification, renewal, confirmation and extension of such Existing Security Agreement, and (ii) the Liens, security interests and other interests in the collateral as described in the Existing Security Agreement (the “Original Collateral”) granted under the Existing Security Agreement are and shall remain legal, valid, binding and enforceable with regard to such Original Collateral. Each Grantor party to the Existing Security Agreement hereby acknowledges and confirms the continuing existence and effectiveness of such Liens, security interests and other interests in the Original Collateral granted under the Existing Security Agreement, and further agrees that the execution and delivery of this Security Agreement and the other Loan Documents shall not in any way release, diminish, impair, reduce or otherwise affect such Liens, security interests and other interests in the Original Collateral granted under the Existing Security Agreement.

(l) Entire Agreement. THIS SECURITY AGREEMENT, THE CREDIT AGREEMENT, AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY

EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.

Annex 1 to the

Security Agreement

SUPPLEMENT NO. [ ] dated as of [ ] (the “Supplement”), to the Amended and Restated Security Agreement dated as of December 17, 2008 (as amended, supplemented or otherwise modified from time to time, the “Security Agreement”), by and among XXXX PETROLEUM, INC., a Delaware corporation (“Borrower”), each subsidiary of Borrower signatory thereto (together with the Borrower, the “Grantors” and individually, a “Grantor”) and Union Bank of California, N.A. as administrative agent under the Credit Agreement (as hereinafter defined) for the benefit of itself and the Secured Parties (as hereinafter defined).

A. Reference is made to the following documents related to extension of credit to the Borrower:

(i) that certain Amended and Restated Credit Agreement dated as of December 17, 2008 (as it may be amended, restated or otherwise modified from time to time, the “Credit Agreement”) by and among the Borrower, the lenders party thereto from time to time (the “Lenders”), and Union Bank of California, N.A., as administrative agent for such Lenders (in such capacity, the “Administrative Agent”), and as issuing lender (in such capacity, the “Issuing Lender”);

(ii) those Hedge Contracts (as defined in the Credit Agreement) that the Borrower, the Guarantors (as defined in the Credit Agreement), or any of their Subsidiaries may from time to time enter into one or more with a Swap Counterparty (as defined in the Credit Agreement), and together with the Administrative Agent, the Issuing Lender, and the Lenders, the “Secured Parties”).

B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Security Agreement and the Credit Agreement.

C. The Grantors have entered into the Security Agreement in order to induce the Lenders to make loans and the Issuing Lender to issue letters of credit under the Credit Agreement. Pursuant to Section 6.15 of the Credit Agreement, each Subsidiary of the Borrower that was not in existence on the date of the Credit Agreement is required to enter into the Security Agreement as a Grantor upon becoming a Subsidiary. Section 17(j) of the Security Agreement provides that additional Subsidiaries of the Borrower may become Grantors under the Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary of the Borrower (the “New Grantor”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Grantor under the Security Agreement in order to induce the Lenders to make additional loans and the Issuing Lender to issue additional letters of credit and as consideration for loans previously made and letters of credit previously issued.

Accordingly, the Administrative Agent and the New Grantor agree as follows:

SECTION 1. In accordance with Section 17(j) of the Security Agreement, the New Grantor by its signature below becomes a Grantor under the Security Agreement with the same force and effect as if originally named therein as a Grantor and the New Grantor hereby agrees (a) to all the terms and provisions of the Security Agreement applicable to it as a Grantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct on and as of the date hereof in all material respects. In furtherance of the foregoing, the New Grantor, as security for the payment and performance in full of the Secured Obligations (as defined in the Security Agreement), does hereby create and grant to the Administrative Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a continuing security interest in and lien on all of the New Grantor’s right, title and interest in and to the Collateral (as defined in the Security Agreement) of the New Grantor. Each reference to a “Grantor” in the Security Agreement shall be deemed to include the New Grantor. The Security Agreement is hereby incorporated herein by reference.

SECTION 2. The New Grantor represents and warrants to the Administrative Agent and the other Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application (regardless of whether enforcement is sought in a proceeding in equity or at law)).

SECTION 3. This Supplement may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Administrative Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of the New Grantor and the Administrative Agent. Delivery of an executed signature page to this Supplement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.

SECTION 4. The New Grantor hereby represents and warrants that set forth on Schedule 1 attached hereto are (a) its sole jurisdiction of formation and type of organization, (b) the location of all records concerning its Accounts, General Intangibles, or any other Collateral, (c) its federal tax identification number and the organizational number, and (d) all names used by it during the last five years prior to the date of this Supplement.

SECTION 5. Except as expressly supplemented hereby, the Security Agreement shall remain in full force and effect.

SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTERESTS HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PLEDGED COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF TEXAS.

SECTION 7. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, neither party hereto shall be required to comply with such provision for so long as such provision is held to be invalid, illegal or unenforceable, but the validity, legality and enforceability of the remaining provisions contained herein and in the Security Agreement shall not in any way be affected or impaired. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8. All communications and notices hereunder shall be in writing and given as provided in the Security Agreement. All communications and notices hereunder to the New Grantor shall be given to it at the address set forth under its signature hereto.

SECTION 9. The New Grantor agrees to reimburse the Administrative Agent for its reasonable out-of-pocket expenses in connection with this Supplement, including the reasonable fees, other charges and disbursements of counsel for the Administrative Agent.

THIS SUPPLEMENT, THE SECURITY AGREEMENT, THE CREDIT AGREEMENT AND THE OTHER LOAN DOCUMENTS, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO.

IN WITNESS WHEREOF, the New Grantor and the Administrative Agent have duly executed this Supplement to the Security Agreement as of the day and year first above written.
