(the "Borrower") in connection with the transactions contemplated in the Credit Agreement. This Opinion is delivered pursuant to Section 3.1(m) of the Credit Agreement, and the Lender is hereby authorized to rely upon this Opinion in connection with the transactions contemplated in the Credit Agreement. Each capitalized term used but not defined herein shall have the meaning assigned to such term in the Credit Agreement. In our representation of the Borrower, we have examined an executed counterpart of each of the following (the "Loan Documents"): (a) the Credit Agreement; (b) the Note; (c) Mortgage, Deed of Trust, Indenture, Security Agreement, Assignment of Production, and Financing Statement dated of even date herewith from the Borrower in favor of the Lender (the "Mortgage"); and (d) Financing Statements from the Borrower, as debtor, constituent to the Mortgage (the "Financing Statement"). We have also examined the originals, or copies certified to our satisfaction, of such other records of the Borrower, certificates of public officials and officers of the Borrower agreements, instruments, and documents as we have deemed necessary as a basis for the opinions hereinafter expressed. In making such examinations, we have, with your permission, assumed: (a) the genuineness of all signatures to the Loan Documents other than those of the Borrower; (b) the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies; (c) the Lender is authorized and has the power to enter into and perform its obligations under the Credit Agreement; (d) the due authorization, execution, and delivery of all Loan Documents by each party thereto other than the Borrower; and (e) the Borrower has title to all Property covered or affected by the Mortgage. Based upon the foregoing and subject to the qualifications set forth herein, we are of the opinion that: 1. The Borrower is a corporation duly organized, legally existing, and in good standing under the laws of its state of incorporation and is duly qualified as a foreign corporation and is in good standing in all jurisdictions wherein the ownership of its Property or the operation of its business necessitates same. 2. The execution and delivery by the Borrower of the Credit Agreement and the borrowings thereunder, the execution and delivery by the Borrower of the other Loan Documents to which the Borrower is a party, and the payment and performance of all Obligations of the Borrower thereunder are within the power of the Borrower, have been duly authorized by all necessary corporate action, and do not (a) require the consent of any Governmental Authority, (b) contravene or conflict with any Requirement of Law, (c) to our knowledge after due inquiry, contravene or conflict with any indenture, instrument, or other agreement to which the Borrower is a party or by which any Property of the Borrower may be presently bound or encumbered, or (d) result in or require the creation or imposition of any Lien upon any Property of the Borrower other than as contemplated by the Loan Documents. 3. The Loan Documents to which the Borrower is a party constitute legal, valid, and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms. 4. The forms of the Mortgage and the Financing Statement and the description of the Mortgaged Property (as such term is defined in the Mortgage and so used herein) situated in the State of Texas (the "State") satisfy all applicable Requirements of Law of the State and are legally sufficient under the laws of the State to enable the Lender to realize the practical benefits purported to be afforded by the Mortgage. 5. The Mortgage creates a valid lien upon and security interest in all Mortgaged Property situated in the State to secure the Indebtedness (as such term is defined in the Mortgage and so used herein). 6. The Mortgage and the Financing Statement are in satisfactory form for filing and recording in the offices described below. 7. The filing and/or recording, as the case may be, of (a) the Mortgage in the office of the county clerk of each county in the State in which any portion of the Mortgaged Property is located, and as a financing statement and utility security instrument in the office of the Secretary of State of the State, and (b) the Financing Statement in the Uniform Commercial Code records in each county in the State in which any portion of the Mortgaged Property is located are the only recordings or filings in the State necessary to perfect the liens and security interests in the Mortgaged Property created by the Mortgage or to permit the Lender to enforce in the State its rights under the Mortgage. No subsequent filing, re-filing, recording, or re-recording will be required in the State in order to continue the perfection of the liens and security interests created by the Mortgage except that (a) a continuation statement must be filed with respect to the Mortgage filed as a financing statement in the office of the Secretary of State of the State and with respect to the Financing Statement in the Uniform Commercial Code records in each county in the State in which any portion of the Mortgaged Property is located, each within six months prior to the expiration of five years from the date of the relevant initial financing statement filing, (b) a subsequent continuation statement must be filed within six months prior to the expiration of each subsequent five-year period from the date of each initial financing statement filing, and (c) amendments or supplements to the Mortgage filed as a financing statement and the Financing Statement and/or additional financing statements may be required to be filed in the event of a change in the name, identity, or structure of the Borrower or in the event the financing statement filing otherwise becomes inaccurate or incomplete. 8. To our knowledge after due inquiry, except as disclosed in Exhibit to the Credit Agreement, no litigation or other action of any nature affecting the Borrower is pending before any Governmental Authority or threatened against the Borrower. To our knowledge after due inquiry, no unusual or unduly burdensome restriction, restraint, or hazard exists by contract, Requirement of Law, or otherwise relative to the business or operations of the Borrower or the ownership and operation of any Properties of the Borrower other than such as relate generally to Persons engaged in business activities similar to those conducted by the Borrower. 9. No authorization, consent, approval, exemption, franchise, permit or license of, or filing (other than filing of Security Instruments in appropriate filing offices) with, any Governmental Authority or any other Person is required to authorize or is otherwise required in connection with the valid execution and delivery by the Borrower of the Loan Documents or any instrument contemplated thereby, or the payment performance by the Borrower of the Obligations. 10. No transaction contemplated by the Loan Documents is in violation of any regulations promulgated by the Board of Governors of the Federal Reserve System, including, without limitation, Regulations G, T, U, or X. 11. The Borrower is not, nor is the Borrower directly or indirectly controlled by or acting on behalf of any Person which is, an "investment company" or an "affiliated person" of an "investment company" within the meaning of the Investment Company Act of 1940, as amended. 12. The Borrower is not a "holding company," or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company," within the meaning of the Public Utility Holding Company Act of 1935, as amended.

The validity, binding effect, and enforceability of the Loan Documents may be limited or affected by bankruptcy, insolvency, moratorium, reorganization, or other similar laws affecting rights of creditors generally, including, without limitation, statutes or rules of law which limit the effect of waivers of rights by a debtor or grantor; provided, however, that the limitations and other effects of such statutes or rules of law upon the validity and binding effect of the Loan Documents should not differ materially from the limitations and other effects of such statutes or rules of law upon the validity and binding effect of credit agreements, promissory notes, and security instruments generally. C. The enforceability of the respective obligations of the Borrower under the Loan Documents is subject to general principles of equity (whether such enforceability is considered in a suit in equity or at law). This Opinion is furnished by us solely for the benefit of the Lender in connection with the transactions contemplated by the Loan Documents and is not to be quoted in whole or in part or otherwise referred to or disclosed in any other transaction.
