person controlling the Underwriters) on account of any such untrue statement or alleged untrue statement, or any such omission or alleged omission, under the caption UNDERWRITING or (B) the Issuer on account of any such untrue statement or alleged untrue statement, or any such omission or alleged omission, under the caption THE ISSUER or under the caption LITIGATION The Issuer or (iii) a breach of any of the representations included in this Bond Purchase Contract; and provided further, however, that the Company shall not be liable to the Underwriters for any such Losses (A) if the person asserting the Loss purchased Bonds from the Underwriters, if delivery to such person of the Official Statement, as then amended or supplemented, would have been a valid defense to the action from which such Loss arose, and copies of an Official Statement, as then so amended or supplemented, were made available to the Underwriters and a copy was not delivered to such person by or on behalf of the Underwriters or (B) to the extent caused by the gross negligence, willful misconduct or bad faith of the person seeking indemnity (other than the Issuer).

(b) Each Indemnified Party agrees that, upon the receipt of notice of the commencement of any action against it, in respect of which indemnity may be sought on account of any indemnity agreement contained herein, it will promptly give written notice of the commencement thereof to the Company, but the failure so to notify the Company of any such action shall not relieve the Company from any liability which it may have to the Indemnified Party otherwise than under this Section 9 unless such failure restricts or limits the Companys ability to defend such action. In case such notice of any action shall be so given, the Company shall be entitled to participate at its own expense in the defense or, if it elects, with the consent of each Indemnified Party, to assume (in conjunction with any other Indemnifying Party) the defense of such action, in which event such defense shall be conducted by counsel chosen by the Company reasonably satisfactory to the Indemnified Party who shall be defendant or defendants in such action, and such defendant or defendants shall bear the fees and expense of any additional counsel retained by them; provided, that if the Company shall elect not to assume the defense of such action, the Company will reimburse such Indemnified Party for the reasonable and customary legal fees and out-of-pocket expenses of any counsel retained by such Indemnified Party; provided, further that, if the defendants in any such action include one or more of the Indemnified Party and the Company, and counsel for any Indemnified Party shall have reasonably concluded that there may be a conflict of interest involved in the representation by such counsel of both the Company and any one or more of the Indemnified Party, the Indemnified Party shall have the right to select separate counsel (subject to the approval of the Company) to participate in the defense of such action on behalf of such Indemnified Party and the Company shall be liable for the reasonable and customary expenses of separate counsel representing such Indemnified Party who is a party to such action, in addition to local counsel.

This Bond Purchase Contract shall inure to the benefit of the Issuer, the Underwriters, the Company, and their respective successors and assigns and to the persons described in Section 9.

In connection with our role as bond counsel, we have reviewed the Bond Purchase Contract, the Indenture, the Loan Agreement, and such other documents, certificates and matters to the extent we deemed necessary to render the opinions set forth herein.

The opinions expressed herein are based on an analysis of existing laws, regulations, rulings and court decisions. Such opinions may be affected by actions taken or omitted or events occurring after the date hereof. We have not undertaken to determine, or to inform any person, whether any such actions are taken or omitted or events do occur. We have assumed the genuineness of all documents and signatures presented to us (whether as originals or as copies) and the due and legal execution and delivery thereof by, and validity against, any party other than the Issuer. We have not undertaken to verify independently, and have assumed, the accuracy of the factual matters represented, warranted or certified in the documents referred to in the preceding paragraph. We have further assumed compliance with all covenants and agreements contained in such documents. In addition, we call attention to the fact that the rights and obligations under the Bonds, the Indenture, the Loan Agreement, the Note and the Bond Purchase Contract and their enforceability are subject to bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium and other laws relating to or affecting

A-1

creditors rights, to the application of equitable principles and to the exercise of judicial discretion in appropriate cases. We express no opinion with respect to any indemnification, contribution, choice of law, choice of forum or waiver provisions contained therein.

2. The Bond Purchase Contract has been duly authorized, executed and delivered by the Issuer and (assuming due authorization, execution and delivery by and validity against you) is a valid and binding agreement of the Issuer.

3. The statements contained in the Official Statement under the captions THE BONDS, SECURITY FOR THE BONDS and in APPENDIX D, insofar as such statements purport to summarize certain provisions of the Indenture, the Loan Agreement, the Note and the Bonds, present fairly and accurately the information purported to be summarized thereby. The statements contained in the Official Statement under the caption TAX MATTERS, to the extent that such statements describe our firms opinion as to certain provisions of federal income tax law, are fair and accurate summaries of such opinion.

This letter is furnished by us as bond counsel. No attorney client relationship has existed or exists between us and you in connection with the Bonds or by virtue of this letter. Our engagement with respect to the Bonds has concluded with their issuance, and we have no obligation to update this letter. This letter is delivered to you as underwriters of the Bonds, is solely for your benefit as such underwriters and is not to be used, circulated, quoted or otherwise referred to or relied upon for any other purpose or by any other person, except that a copy of this opinion letter may be included in the transcript of proceedings provided in connection with the issuance of the Bonds.

(k) Surplus Account. The Surplus Account (as defined in the Control Agreement) is a securities account as defined in Section 8-501(a) of the Texas UCC, and all property from time to time credited to the Surplus Accounts are financial assets as defined in Section 8-102(a)(9) of the Texas UCC.

Our Opinions

Based on and subject to the foregoing and the other limitations, assumptions, qualifications and exclusions set forth in this opinion letter, we are of the opinion that:

1. Organizational Status. Based solely upon the Delaware Good Standing Certificate, the Borrower is a limited liability company validly existing and in good standing under the laws of the State of Delaware as of the date of the Delaware Good Standing Certificate. Based solely on the Texas Good Standing Certificates, the Borrower is duly authorized as a foreign limited liability company to transact business in Texas.

2. Power and Authority. The Borrower has the limited liability company power and authority to execute, deliver and perform the terms and provisions of each Subject Document to which it is party. The Borrower has taken all necessary limited liability company action to authorize the execution, delivery and performance of the Subject Documents and the execution and delivery of the Official Statement and the use of the Preliminary Official Statement and the Official Statement by the Underwriter in connection with the offering and sale of the Bonds on behalf of the Borrower.

3. Execution, Validity and Enforceability. The Borrower has duly executed and delivered each Subject Document to which it is party, and each such Subject Document constitutes its valid, binding and enforceable obligation.

4. Noncontravention. Neither the execution, delivery and performance by the Borrower of any Subject Document to which it is a party, nor the compliance by the Borrower with the terms and provisions thereof, (a) violates any present law, statute or regulation

of the State of Texas, or the United States that, in each case, is applicable to the Borrower; (b) violates any provision of the Organizational Documents of the Borrower; or (c) results in any breach of any of the terms of, or constitutes a default under, any Reviewed Document or results in the creation or imposition of any lien, security interest or other encumbrance (except as contemplated by the Subject Documents) upon any assets of the Borrower pursuant to the terms of any Reviewed Document.

5. Governmental Approvals. No consent, approval or authorization of, or filing with, any governmental authority of the State of Texas or the United States (or any governmental authority of the State of Delaware pursuant to the Delaware Limited Liability Company Act or Article 9 of the Delaware UCC) that, in each case, is applicable to the Borrower is required for (a) the due execution and delivery by the Borrower of any Subject Document to which it is a party or the consummation by the Borrower on the date hereof of the transactions contemplated thereby or (b) the validity, binding effect or enforceability of any Subject Document to which the Borrower is a party, except (i) in each case as have previously been made or obtained, (ii) filings and recordings which are necessary to perfect the security interests granted under the Security Agreement and the Deed of Trust, and (iii) consents, approvals, authorizations or filings as may be required to be obtained or made by the Other Parties as a result of their involvement in the transactions contemplated by the Subject Documents and the Official Statement.

6. UCC Matters. (a) After giving effect to the making of the loans or other extensions of credit on the date hereof as contemplated by the Indenture and the Loan Agreement, the Security Agreement is effective to create a valid security interest in favor of the Trustee to secure the Borrowers obligations described therein in all right, title and interest of the Borrower in and to all personal property included within the term Collateral (as defined in the Security Agreement) in which a security interest can be granted under Article 9 of the Texas UCC (collectively, the Article 9 Collateral).

(b) Assuming that the UCC Financing Statement has been duly submitted for filing in the UCC Filing Office with the appropriate filing fees tendered, or duly accepted for filing by the UCC Filing Office, the Trustee will have a perfected security interest in those items of the Article 9 Collateral in which a security interest may be perfected under Article 9 of the Delaware UCC by the filing of a financing statement in the UCC Filing Office.

(c) If the laws of the State of Texas were the local law of the banks jurisdiction for the purposes of Section 9-304 of the Texas UCC, then the provisions of the Security Agreement, together with the Control Agreement, are effective to give the Trustee control (within the meaning of Section 9-104 of the Texas UCC) over deposit accounts (as defined in Section 9-102(a) of the Texas UCC) maintained with the Depository Institution as to which the Borrower is the account holder (the Deposit Accounts), and to perfect (within the meaning of Section 9-314 of the Texas UCC) the Trustees security interest in the Deposit Accounts.

(d) If the laws of the State of Texas were the local law of the securities intermediarys jurisdiction for the purposes of Section 9-305 of the Texas UCC, then the provisions of the Security Agreement, together with the Control Agreement, are effective to give the Trustee control (within the meaning of Section 9-106 of the Texas UCC) over the Surplus Account maintained with the Securities Intermediary as to which the Borrower is the account holder, and to perfect (within the meaning of Section 9-314 of the Texas UCC) the Trustees security interest in the Surplus Account.

7. Deed of Trust. The Deed of Trust (i) is in appropriate form for recording in the office of the recorder of deeds (or equivalent office) in Dallas County, Texas (the County Filing Office), and (ii) upon filing and recording thereof in the County Filing Office, creates and constitutes a valid deed of trust lien in favor of the trustee named therein in the Borrowers right, title and interest in the portions of the Premises (as defined in the Deed of Trust) constituting real property.

8. Official Statement. With respect to the Official Statement, we have neither been called upon to express nor do we express any opinion or render any advice on the accuracy, completeness or sufficiency of any information or statement under the headings INTRODUCTION, THE ISSUER, THE BORROWER AND THE PROJECT PARTICIPANTS-Project Participants, PROJECT FLOW BLOCK DIAGRAM, PROJECTED PROJECT REVENUES AND EXPENSES, SHELL ENERGY NORTH AMERICA (US), L.P., INVESTMENT CONSIDERATIONS, LITIGATION-The Issuer, UNDERWRITING, RATINGS, APPROVAL OF LEGAL PROCEEDINGS, and MISCELLANEOUS, or in Appendices B, C and G thereto or any information with respect to The Depository Trust Company or its procedures. Subject to the foregoing, without independent investigation or verification and without assumption of any responsibility for the factual accuracy, completeness or sufficiency of any information in the Official Statement or the accuracy, fairness or completeness of the statements included in the Official Statement, we hereby advise you that no information has come to our knowledge that causes us to believe that the Official Statement contains any untrue statement of a material fact or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Our advice in this paragraph does not apply to either (a) any informational report or document incorporated by reference into the Official Statement or (b) any financial statements or financial or statistical data contained in the Official Statement, as to all of which no opinion is rendered and no advice is given.

9. Proceedings. To our knowledge, there is no outstanding judgment, action, suit or proceeding pending against the Borrower before any court, governmental agency or arbitrator which challenges the legality, validity, binding effect or enforceability of any Subject Document to which the Borrower is a party.

Qualifications and Limitations

The opinions set forth above are subject to the following qualifications and limitations:

(q) Applicable Law. Our opinions are limited to the federal law of the United States, the Delaware Limited Liability Company Act, Article 9 of the Delaware UCC and the laws of the State of Texas, and we do not express any opinion concerning any other law.

(r) Bankruptcy. Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, laws relating to preferences and fraudulent transfers or conveyances), reorganization, moratorium and other similar laws affecting creditors rights generally.

(s) Equitable Principles. Our opinions are subject to the effect of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing. In applying such principles, a court, among other things, might limit the availability of specific equitable remedies (such as injunctive relief and the remedy of specific performance), might not allow a creditor to accelerate maturity of debt or exercise other remedies upon the occurrence of a default deemed immaterial or for non-credit reasons or might decline to order a debtor to perform covenants in a Subject Document. Further, a court may refuse to enforce a covenant if and to the extent that it deems such covenant to be violative of applicable public policy, including, for example, provisions requiring indemnification of any Other Party against liability for its own wrongful or negligent acts.

(t) Unenforceability of Certain Provisions. Certain of the provisions contained in any Subject Document may be unenforceable or ineffective, in whole or in part. Such provisions include, for example, those which: waive or do not require notice in connection with the exercise of remedies; require waivers or amendments to be made only in writing; purport to waive the right of statutory or equitable redemption; authorize a standard for decision other than commercial reasonableness; authorize the taking of possession of any collateral without judicial process or otherwise authorize self-help or authorize the Trustee to act on behalf of, or exercise the rights of, the Borrower; characterize any assignment of rents, leases and/or other documents, rights and interests as absolute rather than a collateral assignment for security purposes; purport to validate otherwise invalid provisions of other documents incorporated or referred to in any Subject Document; attempt to appoint a person as an attorney-in-fact for the Borrower or any other person; attempt to prohibit or restrict the transfer, alienation, mortgaging, encumbering or hypothecation of the properties covered by or described in the Subject Documents; purport to absolve a person from liability for, or the consequences of, its negligence, gross negligence, willful misconduct or breach of obligations; purport to waive stay, extension or usury laws; purport to alter the priority of any lien or security interest; subrogate the Trustee or any other party to the rights of others; permit partial foreclosure of the Deed of Trust; or provide for distribution of foreclosure proceeds other than in accordance with the laws of Texas. The inclusion of such provisions does not, however, render any Subject Document invalid as a whole, and each Subject Document contains, in our opinion, adequate remedial provisions for the ultimate practical realization of the principal benefits purported to be afforded by such Subject Document, subject to the other qualifications contained in this opinion letter. We note, however, that the unenforceability of such provisions may result in delays in enforcement of the rights and remedies of the Trustee under any Subject Document, and we express no opinion as to the economic consequences, if any, of such delays.

(u) Knowledge. Whenever our opinions or qualifications are stated to be to our knowledge or known to us (or words of similar import), it means the actual knowledge of the particular McGuireWoods LLP attorneys who have represented the Borrower in connection with the Subject Documents and who have given substantive attention to the preparation and negotiation thereof. Except as expressly set forth herein, we have not undertaken any independent investigation (including, without limitation, conducting any review, search or investigation of any public files or records or dockets or any review of our files) to determine the existence or absence of any facts, and no inference as to our knowledge concerning such facts should be drawn from our reliance on the same in connection with the preparation and delivery of this opinion letter.

(v) Noncontravention and Governmental Approvals. With respect to the opinions expressed in paragraphs 4(a) and 5 above, our opinions are limited to our review of only those laws and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Subject Documents and to business organizations generally.

(w) Reviewed Documents. With respect to our opinion in paragraph 4(c) above, we have assumed that the law governing each Reviewed Document would have the same effect as the law of the State of Texas, and we express no opinion as to any violation not readily ascertainable from the face of any Reviewed Document or arising from any cross-default

provision insofar as it relates to a default under an agreement that is not a Reviewed Document or arising under a covenant of a financial or numerical nature or requiring computation.

(x) Use of Proceeds. With respect to our opinion in paragraph 4(a) above as it relates to Regulations T, U and X of the Board of Governors of the Federal Reserve System, we have assumed that the Borrower will comply with the provisions of the Loan Agreement relating to the use of proceeds.

(y) Material Changes to Terms. Provisions in the Subject Documents which provide that any obligations of the Borrower thereunder will not be affected by the action or failure to act on the part of any Other Party or by an amendment or waiver of the provisions contained in the other Subject Documents might not be enforceable under circumstances in which such action, failure to act, amendment or waiver so materially changes the essential terms of the obligations that, in effect, a new contract has arisen between such Other Party and the Borrower.

(z) Incorporated Documents. The foregoing enumerated opinions do not relate to (and we have not reviewed) any documents or instruments other than as expressly stated in this opinion letter, and we express no opinion as to such other documents or instruments (including, without limitation, any documents or instruments referenced or incorporated in any of the Subject Documents) or as to the interplay between the Subject Documents and any such other documents or instruments.

(aa) Mathematical Calculations. We have made no independent verification of any of the numbers, schedules, formulae or calculations in the Subject Documents, and we render no opinion with regard to the accuracy, validity or enforceability of any of them.

(bb) Security Interest in Proceeds. The continuation and perfection of the Trustees security interest in the proceeds of the Article 9 Collateral are limited to the extent set forth in Section 9-315 of the Texas UCC and Section 9-315 of the Delaware UCC, as applicable.

(cc) Actions to Continue Effectiveness. We express no opinion as to any actions that may be required to be taken periodically under the Texas UCC, the Delaware UCC or any other applicable law subsequent to the filing of the UCC Financing Statement for the effectiveness of such Financing Statement, or the validity or perfection of any security interest, to be maintained.

(dd) After-Acquired Property. A security interest in any Article 9 Collateral that constitutes after-acquired collateral does not attach until the Borrower has rights in such after-acquired collateral.

(ee) Property Acquired after Commencement of Bankruptcy Case. In the case of property which becomes part of the Article 9 Collateral after the date hereof, Section 552 of the Bankruptcy Reform Act of 1978, as amended (the Bankruptcy Code), limits the extent to which property acquired by a debtor after the commencement of a case under the 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.

(ff) After-acquired Property as Voidable Preference. In the case of property which becomes part of the Article 9 Collateral after the date hereof, Section 547 of the Bankruptcy Code provides that a transfer is not made until the debtor has rights in the property transferred, so a security interest in after-acquired property which is security for other than a contemporaneous advance may be treated as a voidable preference under the conditions (and subject to the exceptions) provided by Section 547 of the Bankruptcy Code.

(gg) Rights of Third Parties in Certain Collateral. The rights of the Trustee with respect to Article 9 Collateral consisting of accounts, instruments, licenses, leases, contracts or other agreements will be subject to the claims, rights and defenses of the other parties thereto against the Borrower.

(hh) Licenses or Permits as Collateral. In the case of any Article 9 Collateral consisting of licenses or permits issued by governmental authorities or other persons or entities, the Borrower may not have sufficient rights therein for the security interest of the Trustee to attach and, even if the Borrower has sufficient rights for the security interest of the Trustee to attach, the exercise of remedies may be limited by the terms of the license or permit or require the consent of the governmental authority issuing such license or permit.

(ii) Collateral Evidenced by Instruments. We note that, if any of the Article 9 Collateral is evidenced by instruments or tangible chattel paper or any other property in which a security interest may be perfected by taking possession (in each case as defined, and as provided for, in the Texas UCC), the local law of the jurisdiction where such property is located will govern the priority of a possessory security interest in such property and the effect of perfection or non-perfection of a non-possessory security interest in such property.

(jj) Other UCC Limitations. Such opinions may also be limited by Sections 9-320, 9-323, 9-335 and 9-336 of the Texas UCC and Sections 9-320, 9-323, 9-335 and 9-336 the Delaware UCC.

(kk) Texas Property Code. We call to your attention that the enforceability of the Deed of Trust may be limited by the provisions of Sections 51.003 through 51.005 of the Texas Property Code, which relate to deficiencies resulting from the foreclosure of contract liens relating to real property.

(ll) Usury. We express no opinion as to whether the Subject Document comply with any statutory, regulatory or other loan limits applicable to the parties thereto or comply with any usury statutes or any other statutes, laws, rules or regulations which prescribe permissible and lawful investments for any party (either as to type, amount, percentage of total investments or otherwise).

Our opinions in this Opinion (herein so called) are limited in all respects to the substantive law of the State of Texas (the State) and the federal law of the United States of America, and we assume no responsibility as to the applicability thereto, or to the effect thereon, of the laws of any other jurisdiction.

We have been furnished with and examined originals or copies, certified or otherwise identified to our satisfaction, of all such records of the Issuer, agreements and other instruments, certificates of officers and representatives of the Issuer, certificates of public officials and other documents and we have had such discussions with appropriate officers of the Issuer as we have deemed necessary or desirable as a basis for the opinions hereinafter expressed. As to questions of fact material to such opinions, we have, where relevant facts were not independently verified or established, relied upon certificates of and discussions with officers of the Issuer.

For purposes of this Opinion, we have assumed: (i) the genuineness or all signatures on all documents (other than that of the Issuer on the Issuer Transaction Documents); (ii) the authenticity of all documents submitted to us as originals; (iii) the conformity to the originals of all documents submitted to us as copies; (iv) the correctness and accuracy of all facts set forth in all certificates and reports identified in this Opinion; (v) the due authorization, execution and delivery of and the validity and binding effect of the Issuer Transaction Documents with regard to the parties to the Issuer Transaction Documents other than the Issuer; (vi) each document submitted to us for review is accurate and complete; (vii) there has been no mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (viii) the conduct of the parties to the transactions has complied with any requirement of good faith, fair dealing and conscionability; (ix) there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of the Issuer Transaction Documents; (x) the Issuer will not in the future take any discretionary action (including a decision not to act) permitted under the Issuer Transaction Documents that would result in a violation of law or constitute a breach or default under any other agreement or court order; and (xi) all parties to the Issuer Transaction Documents will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Issuer Transaction Documents.

To the best of our knowledge, without independent investigation, there is no action, suit, proceeding or investigation at law or in equity before or by any court, public board or public body, pending or threatened against the Issuer, in which an unfavorable decision, finding or ruling would adversely affect the validity or enforceability of the Issuer Transaction Documents or the transactions contemplated therein.

6.
