The Company hereby agrees with the several Purchasers as follows:

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the several Purchasers that:

(a) A preliminary offering circular, dated October 23, 2006, as supplemented by the supplement thereto, dated October 30, 2006 (together, the “Preliminary Offering Circular”) relating to the Offered Securities to be offered by the Purchasers and a final offering circular (the “Final Offering Circular”) disclosing the offering price and other final terms of the Offered Securities and is dated as of the date of this Agreement (even if finalized and issued subsequent to the date of this Agreement) have been or will be prepared by the Company. “General Disclosure Package” means the Preliminary Offering Circular, together with any Issuer Free Writing Communication (as hereinafter defined) existing at the Applicable Time (as hereinafter defined) and the information in which is intended for general distribution to prospective investors, as evidenced by

As of the date of this Agreement and as of the Closing Date, the Final Offering Circular does not, and will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. At the Applicable Time and as of the Closing Date, neither (i) the General Disclosure Package, nor (ii) any individual Supplemental Marketing Material (as hereinafter defined), when considered together with the General Disclosure Package, included nor will include any untrue statement of a material fact or omitted or will omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

If, at any time prior to the completion of the resale of the Offered Securities by the Purchasers, there occurs an event as a result of which the Preliminary Offering Circular or the Final Offering Circular, the General Disclosure Package or any Supplemental Marketing Material included or would include an untrue statement of a material fact or omitted or would omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at such time, not misleading, or if it is necessary at any such time to amend or supplement the Preliminary Offering Circular or the Final Offering Circular, the General Disclosure Package or any Supplemental Marketing Material to comply with any applicable law, the Company promptly will notify Credit Suisse of such event and promptly will prepare, at its own expense, an amendment or supplement which will correct such statement or omission. Neither Credit Suisse’s consent to, nor the Purchasers’ delivery to offerees or investors of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 6. The first sentence of this subsection does not apply to statements in or omissions from the Preliminary Offering Circular or the Final Offering Circular, the General Disclosure Package or any Supplemental Marketing Material made in reliance upon and in conformity with written information furnished to the Company by any Purchaser through Credit Suisse specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 8(b) hereof.

(b) The Company will furnish to Credit Suisse copies of the Preliminary Offering Circular, each other document comprising a part of the General Disclosure Package, the Final Offering Circular, all amendments and supplements to such documents and each item of Supplemental Marketing Material, in each case as soon as available and in such quantities as Credit Suisse reasonably requests. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company will promptly furnish or cause to be furnished to Credit Suisse (and, upon request, to each of the other Purchasers) and, upon request of holders and prospective purchasers of the Offered Securities, to such holders and purchasers, copies of the information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to

Rule 144A(d)(4) under the Securities Act (or any successor provision thereto) in order to permit compliance with Rule 144A in connection with resales by such holders of the Offered Securities. The Company will pay the expenses of printing and distributing to the Purchasers all such documents.

(c) The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions in the United States and Canada as Credit Suisse designates and will continue such qualifications in effect so long as required for the resale of the Offered Securities by the Purchasers, provided that the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any such state or take any action that would subject it to taxation based on its income or revenues in any jurisdiction where it is not currently subject to taxation.

(d) During the period of two years hereafter, the Company will furnish to Credit Suisse and, upon request, to each of the other Purchasers, as soon as practicable after the end of each fiscal year, a copy of its annual report to shareholders for such year; and the Company will furnish to Credit Suisse and, upon request, to each of the other Purchasers as soon as available, a copy of each report or other document mailed to stockholders or furnished to the Commission; provided that such annual reports, reports or other documents shall be deemed to have been provided if such annual report, report or other document is available through ▇▇▇▇▇ or on or through the Company’s website.

(e) During the period of two years after the Closing Date, the Company will, upon request, furnish to Credit Suisse, each of the other Purchasers and any holder of Offered Securities a copy of the restrictions on transfer applicable to the Offered Securities.

(f) During the period of two years after the Closing Date, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Offered Securities that have been reacquired by any of them.

(g) During the period of two years after the Closing Date, the Company will not be or become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act.

(h) The Company will pay all expenses incidental to the performance of its obligations under this Agreement, the Indenture, the Security Documents and the Registration Rights Agreement, including (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection with the execution, issue, authentication, packaging and initial delivery of the Offered Securities and, as applicable, the Exchange Securities, the preparation and printing of this Agreement, the Registration Rights Agreement, the Offered Securities, the Indenture, the Security Documents, the Preliminary Offering Circular, any other documents comprising any part of the General Disclosure Package, the Final Offering Circular, all amendments and supplements thereto, each item of Supplemental Marketing Material and any other document relating to the issuance, offer, sale and delivery of the Offered Securities and, as applicable, the Exchange Securities; (iii) all filing costs and expenses relating to the perfection of security interests in the Collateral, as set forth in the Security Documents; (iv) the fees and expenses of Stone & ▇▇▇▇▇▇▇ Management Consultants, Inc. (the “Independent Engineer”); (v) the cost of qualifying the Offered Securities for trading in The Portal^SM Market (“PORTAL”) and any expenses incidental thereto; (vi) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities; (vii) any expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities or the Exchange Securities for sale under the laws of such jurisdictions in the United States and Canada as Credit Suisse designates and the printing of memoranda relating thereto; (viii) all of the fees and disbursements of counsel to the Purchasers; (ix) for any fees charged by investment rating agencies for the rating of the Offered Securities or the Exchange Securities; (x)

the fees and expenses of the Collateral Trustee (as defined in the Indenture) and the Collateral Trustee’s counsel in connection with the Security Documents; and (xi) for expenses incurred in distributing the Preliminary Offering Circular, any other documents comprising any part of the General Disclosure Package, the Final Offering Circular (including any amendments and supplements thereto) and any Supplemental Marketing Material to the Purchasers. The Company will also pay or reimburse the Purchasers (to the extent incurred by them) for all travel expenses of the Purchasers and the Company’s officers and employees and any other expenses of the Purchasers and the Company in connection with attending or hosting meetings with prospective purchasers of the Offered Securities from the Purchasers, including the costs of the private jet and the Company’s officers’ and employee’s hotel costs, except that the Company shall not be responsible for the Purchasers’ hotel costs and travel costs (except for flights on the private jet, which the Company shall be responsible for) in connection with the roadshow.

(i) In connection with the offering, until Credit Suisse shall have notified the Company and the other Purchasers of the completion of the resale of the Offered Securities, neither the Company nor any of its affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(j) For a period of 90 days after the date of the Final Offering Circular, the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act (other than in respect of the Exchange Securities) relating to, any United States dollar-denominated debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing (other than in respect of the Exchange Securities), without the prior written consent of Credit Suisse. The Company will not at any time offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any securities under circumstances where such offer, sale, pledge, contract or disposition would cause the exemption afforded by Section 4(2) of the Securities Act or the safe harbor of Regulation S thereunder to cease to be applicable to the offer and sale of the Offered Securities.

6. Free Writing Communications. (a) The Company represents and agrees that, unless it obtains the prior consent of Credit Suisse, and each Purchaser represents and agrees that, unless it obtains the prior consent of the Company and Credit Suisse, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Communication.

(b) The Company consents to the use by any Purchaser of a Free Writing Communication that (i) contains only (A) information describing the preliminary terms of the Offered Securities or their offering or (B) information that describes the final terms of the Offered Securities or their offering and that is included in the Terms Communication or is included in or is subsequently included in the Final Offering Circular or (ii) does not contain any information about the Company or its securities that was provided by or on behalf of the Company, it being understood and agreed that any such Free Writing Communication referred to in clause (i) or (ii) shall not be an Issuer Free Writing Communication for purposes of this Agreement.

7. Conditions of the Obligations of the Purchasers. The obligations of the several Purchasers to purchase and pay for the Offered Securities will be subject to the accuracy of the representations and warranties on the part of the Company herein, to the accuracy of the statements of officers of the Company made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

8. Indemnification and Contribution.

(a) The Company will indemnify and hold harmless each Purchaser, its officers, partners, members, directors and its affiliates and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Purchaser may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Circular or the Final Offering Circular, in each case as amended or supplemented, or any Supplemental Marketing Material or any Issuer Free Writing Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Purchaser through Credit Suisse specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below.

(b) Each Purchaser will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or the Exchange Act or otherwise,

insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Circular or the Final Offering Circular, in each case as amended or supplemented, or any Supplemental Marketing Material or any Issuer Free Writing Communication or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Purchaser through Credit Suisse specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Purchaser consists of the following information in the Preliminary Offering Circular and the Final Offering Circular furnished on behalf of each Purchaser: the fourth sentence in the paragraph under “Risk Factors – Risks Relating to this Offering and the Notes – Your ability to resell the notes may be limited by a number of factors; prices for the notes may be volatile”, the first sentence in the third paragraph under the caption “Plan of Distribution”, the eleventh paragraph except for the first sentence thereof under the caption “Plan of Distribution” and the twelfth paragraph under the caption “Plan of Distribution”; provided, however, that the Purchasers shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Agreement.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any reasonably necessary local counsel) for the Company or each Purchaser, as applicable, and that all such reasonable fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for a Purchaser shall be designated in writing by such Purchaser, and any such separate firm for the Company shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement effected without its written consent unless (i) such settlement is entered into in good faith by the indemnified party more than 45 days after receipt by such indemnifying party of written notice of the proposed settlement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld or delayed, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could

have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company from the sale of the Offered Securities, on the one hand, bear to the total discounts and commissions received by the Purchasers from the Company in connection therewith as provided under this Agreement, on the other hand. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts, fees and commissions received by such Purchaser exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act.

9. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, Credit Suisse may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to Credit Suisse and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 10. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Purchasers pursuant to Section 8 shall remain in effect. If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 7(b), the Company will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Company as if such holders were parties thereto.

13. Representation of Purchasers. You will act for the several Purchasers in connection with this purchase, and any action under this Agreement taken by you jointly or by Credit Suisse will be binding upon all of the Purchasers.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) the Purchasers have been retained solely to act as initial purchasers in connection with the initial purchase, offering and resale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company and the Purchasers has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Purchasers have advised or is advising the Company on other matters;

(c) the Company has been advised that the Purchasers and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Purchasers have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) the Company waives, to the fullest extent permitted by law, any claims it may have against the Purchasers for breach of fiduciary duty or alleged breach of fiduciary duty in connection with the transactions contemplated by this Agreement and agrees that the Purchasers shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws.

17. The Issuer is not, and immediately after giving effect to the issuance and sale of the Initial Securities occurring today and the application of proceeds therefrom as described in the Offering Circular, will not be, an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.

18. Each of the Security Documents is effective to create in favor of the Collateral Trustee for the benefit of the Secured Parties (as defined in such Security Document), a valid and enforceable security interest under the NY UCC in all right, title and interest of the Pledgor party to such Security Document in, to and under the Collateral described in such Security Document to which Article 9 of the NY UCC is applicable (the “Article 9 Collateral”) as collateral security for the Secured Obligations (as defined in such Security Document).

Upon the creation of the security interest referred to in paragraph 18 above and the filing of the Financing Statements in the Filing Office, the security interest referred to in paragraph 18 above in that portion of the Article 9 Collateral in which a security interest may be perfected by the filing of a financing statement under the DE UCC will be perfected.

20. Upon the creation of the security interest referred to in paragraph 18 above and the execution and delivery of the Depositary Agreement, the security interest referred to in paragraph 18 above in that portion of the Article 9 Collateral consisting of (i) a “deposit account” (as defined in Section 9-102(a)(29) of the NY UCC) will be perfected by “control” (within the meaning of section 9-104 of the NY UCC); (ii) a “security entitlement” (as defined in Section 8-102(a)(17) of the NY UCC) credited to a “securities account” (as defined in Section 8-501(a) of the NY UCC) will be perfected by “control” (within the meaning of Section 8-106(d)(2) of the NY UCC); and (iii) a “securities account” (as defined in Section 8-501 of the NY UCC) will be perfected when a security interest in all “security entitlements” carried in such “securities account” is perfected by the means indicated in clause (ii) of this paragraph 20.

21. The security interest referred to in paragraph 18 above in that portion of the Article 9 Collateral consisting of a “certificated security” (as defined in Section 8-102(a)(4) of the NY UCC) represented by a “security certificate” (as defined in Section 8-102(a)(16) of the NY UCC) in bearer form or in registered form will, upon the creation of such security interest referred to in paragraph 18 above, be perfected by the Collateral Trustee taking possession in the State of New York of such “security certificate”, and if the Collateral Trustee takes possession of such “security certificate” for “value” (as defined in Section 1-201(44) of the NY UCC) and without “notice” (within the meaning of Section 8-501 of the NY UCC) of any “adverse claim” (as defined in Section 8-102(a)(1) of the NY UCC) to such “certificated security”, then the Collateral Trustee will be a “protected purchaser” (within the meaning of Section 8-303 of the NY UCC) and will acquire such security interest free of any “adverse claim”.

In addition, we have participated in conferences with officers and other representatives of Sabine Pass GP and the Issuer, the independent registered public accounting firm for the Issuer, your counsel and your representatives at which the contents of the Disclosure Package and the Offering Circular and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Disclosure Package and the Offering Circular (except as and to the extent set forth in paragraphs 6 and 7 above), on the basis of the foregoing (relying with respect to factual matters to the extent we deem

appropriate upon statements by officers of Sabine Pass GP and other representatives of the Issuer), no facts have come to our attention that have led us to believe that (i) the Disclosure Package, as of [ : ] [ ].m. (Eastern Time) on [ ], 2006 (which you have informed us is a time prior to the time of the first sale of the Initial Securities by any Initial Purchaser), contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (ii) the Offering Circular, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, it being understood that we express no opinion, statement or belief in this letter with respect to (i) the historical and pro forma financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon and (ii) any other financial or accounting data, included in, or excluded from, the Offering Circular or the Disclosure Package. Without limiting the foregoing, we call to your attention that (i) the Offering Circular has been prepared in the context of a Rule 144A transaction and not as part of a registration statement under the Securities Act, and (ii) the Offering Circular does not contain all information that would be required in a registration statement under the Securities Act.

EXHIBIT A-2

[Opinion of Louisiana Counsel]

1. Except for filings which are necessary to perfect the security interests granted under the Documents and such other filings, authorizations or approvals as are specifically contemplated by the Documents, no authorizations or approvals of, and no filings with, any governmental or regulatory authority or agency of the United States, the state of Borrower’s formation, or the State of Louisiana (the “State”) are necessary for the execution, delivery or performance of the Documents by the Borrower.

2. Each of the Documents constitutes the legal, valid and binding obligation of Borrower, enforceable against Borrower in accordance with its terms.

3. The execution and delivery by the Borrower of the Documents and the consummation of the transactions contemplated thereby do not conflict with or violate any federal or State law, rule, regulation or ordinance applicable to Borrower.

4. Subject to the comments and limitations in Paragraph hereof, the choice of law provisions contained in the Documents will be upheld and enforced by the courts of the State and Federal courts sitting in and applying the laws of the State. In this regard, the amounts to be received by Lender as interest in respect of the Global Note, made by the Borrower, as maker, in favor of Lender and under the Indenture constitute lawful interest under the laws of the State and are neither usurious nor illegal.

5. The Mortgage to be recorded in the State is in form satisfactory for recording. The recording of the Mortgage in the office of Clerk of Court for the Parish of Cameron, State of Louisiana, and the filing and recording of the Financing Statements referred to on Schedule 1 hereto in the offices shown on Schedule 1 hereto, are the only recordings or filings necessary to publish notice of and to establish of record the rights of the parties thereto and to perfect the liens and security interests granted by Borrower pursuant to the Mortgage in the real property (including fixtures) covered thereby. Such Financing Statements comply in all respects with applicable provisions of the Uniform Commercial Code as in effect in the State (the “UCC”) and are in appropriate form for filing or recording and the description therein of the property covered thereby is adequate to permit the perfection of such security interests. Upon the execution and delivery of such Mortgage, such liens and security interests shall be created and upon the recording and filing of the Mortgage and Financing Statements as aforesaid, such liens and security interests shall be perfected. No documents or instruments other than those referred to in this paragraph need be recorded, registered or filed in any public office in the State in order to publish notice of the applicable Mortgage or to perfect such liens and security interests or for the validity or enforceability of any of the Documents or to permit Lender to enforce its rights thereunder in the courts of the State.

6. Except for customary filing fees, no recording, filing, privilege or other tax must be paid by either the Borrower or Lender in connection with the execution, delivery, recordation or enforcement of any of the Documents.

7. In accordance with La. R.S. 9:3500D and La. R.S. 12:703, the Loan is exempt from the law of usury under the laws of the State.

8. It is not necessary for Lender to qualify to do business in the State solely to make the Loan and enforce the provisions of the Documents. The making of the Loan and enforcement of the provisions of the Documents will not result in the imposition upon Lender of any taxes of the State, or any subdivision thereof in which the applicable Mortgaged Property is located (including, without limitation, franchise, license, tax on interest received or income taxes), other than taxes which Lender, if and when it becomes the actual and record owner of such Mortgaged Property, by reason of foreclosure under the applicable Mortgage or by dation en paiement, would be required to pay.

9. Except as provided in Paragraph (4) hereof, the foreclosure of the Mortgage to be recorded in the State or exercise of any other remedy provided in the Mortgage will not in any manner restrict, affect or impair the liability of Borrower with respect to the indebtedness secured thereby or the rights and remedies of Lender with respect to the foreclosure or enforcement of any other security interests or liens securing such indebtedness, to the extent any deficiency remains unpaid after application of the proceeds of the foreclosure of such Mortgage or as a result of the exercise of any other remedy.

10. The priority of the lien of the Mortgage to be recorded in the State in respect of all advances or extensions of credit made by Lender under the Indenture on, before or after the date on which such Mortgage is recorded in the appropriate recording office referred to in Paragraph 5 above will be determined by the date of such recording.

11. The priority of the lien of the Mortgage will not be affected by (a) any prepayment of a portion of the Loan, or (b) any increase in or reduction of the outstanding amount of the Loan from time to time.

12. The Mortgage to be recorded in the State creates valid security interests in favor of Lender in the Collateral to the extent the UCC is applicable thereto, as security for the payment or performance of the Obligations (as defined in such Mortgage).

The security interests described in this Paragraph 12 are referred to as the “Security Interests.”

13. The Mortgage contains the terms and provisions necessary to enable Agent, following a default under the Mortgage, to exercise the remedies that are customarily available to a lienholder under the laws of the State.

14. Borrower is duly qualified to do business as a foreign limited partnership in good standing in the State of Louisiana.

15. The Security Agreement is in proper form and, if Louisiana law were to be applied thereto, the Security Agreement would create a legal, valid and binding security interest in and to the Collateral in accordance with the terms thereof, to the extent that the Collateral consists of personal property in which a security interest can be granted under the UCC.
