(A) within the United States to persons whom it reasonably believes to be QIBs in transactions pursuant to Rule 144A under the Securities act (“Rule 144A”) and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A; or

(B) in accordance with the restrictions set forth in Section 4(b) hereof.

(b) The Purchaser acknowledges that the Offered Securities have not been registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of,

U.S. persons except in accordance with Regulation S or pursuant to an exemption from the registration requirements of the Securities Act. The Purchaser represents and agrees that it has offered and sold the Offered Securities and will offer and sell the Offered Securities (i) as part of their distribution at any time and (ii) otherwise until the later of the commencement of the offering and the latest Closing Date, only in accordance with Rule 144A or Rule 903 under the Securities Act. Accordingly, neither such Purchaser nor its affiliates, nor any persons acting on its or their behalf, have engaged or will engage in any directed selling efforts with respect to the Offered Securities, and such Purchaser, its affiliates and all persons acting on its or their behalf have complied and will comply with the offering restrictions requirement of Regulation S. The Purchaser agrees that, at or prior to confirmation of sale of the Offered Securities, other than a sale pursuant to Rule 144A, such Purchaser will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases the Offered Securities from it during the restricted period a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the date of the commencement of the offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meanings given to them by Regulation S.”

Terms used in this subsection (b) have the meanings given to them by Regulation S.

(c) The Purchaser agrees that each of it and its affiliates has not entered and will not enter into any contractual arrangement with respect to the distribution of the Offered Securities except for any such arrangements with the prior written consent of the Company.

(d) The Purchaser agrees that it and each of its affiliates has not solicited offers for, or offered or sold, and will not solicit offers for or sell, the Offered Securities by means of any form of general solicitation or general advertising, within the meaning of Rule 502(c) of Regulation D under the Securities Act or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act, including, but not limited to (i) any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or (ii) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising. The Purchaser agrees, with respect to resales made in reliance on Rule 144A of any of the Offered Securities, to deliver either with the confirmation of such resale or otherwise prior to settlement of such resale a notice to the effect that the resale of such Offered Securities has been made in reliance upon the exemption from the registration requirements of the Securities Act provided by Rule 144A.

5. Certain Agreements of the Company. The Company agrees with the Purchaser that:

(a) The Company will advise CSFB promptly of any proposal to amend or supplement the Offering Document and will not effect such amendment or supplementation without CSFB’s consent, such consent not to be unreasonably withheld. If, at any time prior to the completion of the resale of the Offered Securities by the Purchaser, any event occurs as a result of which the Offering Document as then amended or supplemented would include an 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, the Company promptly will notify CSFB of such event and promptly will prepare, at its own expense, an amendment or supplement which will correct such statement or omission. Neither CSFB’s consent to, nor the Purchaser’ 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.

(b) The Company will furnish to CSFB copies of the Preliminary Offering Circular, the Offering Circular and all amendments and supplements to such documents, in each case as soon as available and in such quantities as CSFB 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 CSFB 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 Purchaser 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 states in the United States as CSFB designates and will continue such qualifications in effect so long as required for the resale of the Offered Securities by the Purchaser 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 after the later of the First Closing Date and the Optional Closing Date, the Company will, upon request, furnish to CSFB and any holder of Offered Securities a copy of the restrictions on transfer applicable to the Offered Securities.

(e) During the period of two years after the later of the First Closing Date and the Optional 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.

(f) The Company will pay all expenses incidental to the performance of its obligations under this Agreement, the Indenture 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, the preparation and printing of the Offered Securities, the Indenture, and the Offering Document and amendments and supplements thereto; (iii) the cost of qualifying the Offered Securities for trading in The Portal^SM Market (“PORTAL”) of The Nasdaq Stock Market, Inc. and any expenses incidental thereto, (iv) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities, (v) any expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions in the United States as CSFB designates and the printing of memoranda relating thereto, and (vi) expenses incurred in distributing the Preliminary Offering Circulars and the Offering Circular (including any amendments and supplements thereto) to the Purchaser, provided that the Company will not be required to reimburse the Purchaser for any of the Purchaser’s out-of-pocket expenses (including fees and disbursements of counsel) incurred in connection with the offering of the Offered Securities.

(g) In connection with the offering, until CSFB shall have notified the Company and the Purchaser 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.

(h) For a period of 90 days after the date of the initial offering of the Offered Securities by the Purchaser, the Company will not offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, any shares of Common Stock of the Company or securities convertible into or exchangeable or exercisable for shares of Common Stock of the Company or warrants or other rights to purchase shares of Common Stock of the Company, without the prior written consent of CSFB, or publicly disclose the intention to make any such offer, sale, pledge or disposition; provided that such restriction shall not apply to: (i) the Offered Securities, (ii) the filing of the shelf registration statement covering resales of the Offered Securities pursuant to the Registration Rights Agreement

(the “Shelf Registration Statement”), (iii) the filing of any registration statement on Form S-8 to register Shares of Common Stock reserved for issuance under the Company’s equity compensation plans; (iv) the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date hereof; (v) grants of employee stock options pursuant to the terms of a plan in effect on the date hereof, (vi) issuances of Common Stock pursuant to the exercise of such options and (vii) the filing of a universal shelf registration statement to register the Company’s Common Stock, preferred stock, debt securities, warrants and units, provided that such universal shelf registration statement is filed on or after the 31^st day following the date of this Agreement date of the filing of the Shelf Registration Statement. 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 to cease to be applicable to the offer and sale of the Offered Securities.

6. Conditions of the Obligations of the Purchaser. The obligations of the Purchaser to purchase and pay for the Firm Securities on the First Closing Date and for the Optional Securities on the Optional Closing Date 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:

(a) The Purchaser shall have received a letter, dated the date of this Agreement, of UHY ▇▇▇▇ Frankfort ▇▇▇▇▇ & ▇▇▇▇ CPAs, LLP and ▇▇▇▇ & Associates LLP, in form and substance reasonably satisfactory to the Purchaser, containing statements and information of the type customarily included in accountants’ “comfort letters” to initial purchasers with respect to the financial statements and certain financial information contained or incorporated by reference in the Preliminary Offering Circular and the Offering Circular; provided that the letter delivered on the Closing Date shall use a “cut-off” date no more than three business days prior to such Closing Date.

(b) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as a whole which, in the judgment of CSFB, is material and adverse and makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities; (ii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of CSFB, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iii) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange or any setting of minimum prices for trading on such exchange; (iv) or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of CSFB, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the offering or sale of and payment for the Offered Securities.

(c) The Purchaser shall have received an opinion, dated the Closing Date, of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, counsel for the Company, in form and substance satisfactory to counsel for the Purchaser, to the effect set forth in Exhibit A hereto and to such further effect as counsel to the Purchaser may reasonably request.

(d) The Purchaser shall have received an opinion, dated the Closing Date, of King & Spalding LLP, special regulatory counsel for the Company, in form and substance satisfactory to counsel for the Purchaser, to the effect set forth in Exhibit A-1 hereto.

(e) The Purchaser shall have received an opinion, dated such Closing Date, of the General Counsel for the Company, in form and substance satisfactory to counsel for the Purchaser, to the effect set forth in Exhibit B hereto and to such further effect as counsel to the Purchaser may reasonably request.

(f) The Purchaser shall have received from Shearman & Sterling LLP, counsel for the Purchaser, such opinion or opinions, dated such Closing Date, with respect to the validity of the Offered Securities, the Offering Circular, the exemption from registration for the offer and sale of the Offered Securities by the Company to the Purchaser and the resales by the Purchaser as contemplated hereby and other related matters as CSFB may require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Shearman & Sterling LLP may rely as to matters governed by Delaware law upon the opinion of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP referred to above.

(g) The Purchaser shall have received a certificate, dated such Closing Date, signed by any two of the chief executive officer, president and the chief financial officer of the Company in which such officers, to the best of their knowledge after reasonable investigation, shall state that the representations and warranties of the Company in this Agreement are true and correct, that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to such Closing Date, and that, subsequent to the respective dates of the most recent financial statements in the Offering Document, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as a whole except as set forth in the Offering Document or as described in such certificate.

(h) The Purchaser shall have received letters, dated such Closing Date, of UHY ▇▇▇▇ Frankfort ▇▇▇▇▇ & ▇▇▇▇ CPAs, LLP and ▇▇▇▇ & Associates LLP which meet the requirements of subsection (a) of this Section, except that the specified date referred to in such subsection will be a date not more than three days prior to such Closing Date for the purposes of this subsection.

(i) The Purchaser shall have received, on or prior to the date of this Agreement, lockup letters substantially in the form of Exhibit C hereto signed by each of the executive officers and directors of the Company listed on Schedule C.

(j) On the First Closing Date, the Registration Rights Agreement, in form and substance reasonably satisfactory to the Purchaser, shall have been duly executed and delivered by the Company and (assuming due execution, delivery and performance by the Purchaser) be in full force and effect.

(k) On the First Closing Date, the Issuer Call Spread, in form and substance reasonably satisfactory to the Purchaser, shall have been duly executed and delivered by the Company and (assuming due execution, delivery and performance by the Purchaser) be in full force and effect.

The Company will furnish the Purchaser with such conformed copies of such opinions, certificates, letters and documents as the Purchaser reasonably requests. CSFB may in its sole discretion waive on behalf of the Purchaser compliance with any conditions to the obligations of the Purchaser hereunder, whether in respect of the Optional Closing Date or otherwise.

7. Indemnification and Contribution. (a) The Company will indemnify and hold harmless the Purchaser, its partners, members, directors, officers and affiliates and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a “Purchaser Indemnified Party”), against any losses, claims, damages or liabilities, to which the 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 Offering Document, or any

amendment or supplement thereto, 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 light of the circumstances under which they were made, not misleading, including 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, and will reimburse the Purchaser Indemnified Party for any legal or other expenses reasonably incurred by such Purchaser Indemnified Party 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 CSFB specifically for use therein, it being understood and agreed that such information consists only of the information described as such in subsection (b) below, and provided, further, that with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from any Offering Document the indemnity agreement contained in this subsection (a) shall not inure to the benefit of the Purchaser that sold the Offered Securities concerned to the person asserting any such losses, claims, damages or liabilities, to the extent that such sale was an initial resale by the Purchaser and any such loss, claim, damage or liability of the Purchaser results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Offered Securities to such person, a copy of the Offering Document (exclusive of any material included therein but not attached thereto) if the Company had previously furnished copies thereof to the Purchaser.

(b) The Purchaser will 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 or Section 20 of the Exchange Act (each, a “Company Indemnified Party”), 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 Offering Document, or any amendment or supplement thereto, 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 CSFB specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by each Company Indemnified Party 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 Offering Document furnished on behalf of the Purchaser: the sixth sentence in the paragraph under “Risk Factors - There is no established trading market for the notes. Your ability to sell the notes may be limited by the absence of an active trading market, and if one develops, it may not be liquid”, the first sentence in the third paragraph under the caption “Plan of Distribution”, the ninth paragraph except for the first sentence thereof under the caption “Plan of Distribution”, the tenth paragraph under the caption “Plan of Distribution”, the fifth sentence of the 11^th paragraph under the caption “Plan of Distribution”; provided, however, that the Purchaser 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 proceeding, claim or 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 proceeding, claim or 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 all indemnified parties, and that all such reasonable fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for the Purchaser Indemnified Parties shall be designated in writing by CSFB and any such separate firm for the Company Indemnified Parties 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 thereunder 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 Purchaser 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 Purchaser 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 Purchaser 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, and the total discounts and commissions received by the Purchaser from the Company in connection therewith as provided under this Agreement, on the other hand, bear, in each case, to the aggregate offering price of the Offered Securities. 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 Purchaser 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 proceeding, 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 price at which the Offered Securities purchased by it were resold 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 Purchaser under this Section shall be in addition to any liability which the respective Purchaser 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.

8. [Intentionally Omitted.]

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Purchaser 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 for any reason the purchase of the Offered Securities by the Purchaser 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 Purchaser pursuant to Section 7 shall remain in effect, and if any Offered Securities have been purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall remain in effect.

10. Notices. All communications hereunder will be in writing and, if sent to the Purchaser will be mailed, delivered or telegraphed and confirmed to the Purchaser, c/o Credit Suisse First Boston LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at Cheniere Energy, Inc., ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇; provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to such Purchaser.

11. 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 7, 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 hereto.

12. Intentionally omitted.

13. 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.

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

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

(b) the price of the Offered Securities set forth in this Agreement was established by the Company following discussions and arm’s-length negotiations with CSFB, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

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

(d) it waives, to the fullest extent permitted by law, any claims it may have against CSFB for breach of fiduciary duty or alleged breach of fiduciary duty in connection with the transactions contemplated by this Agreement and agrees that CSFB 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.

15. 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.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Purchaser’s understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement between the Company and the Purchaser in accordance with its terms.

Exhibit A

Opinion of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP

1. The Issuer is validly existing as a corporation and in good standing under the General Corporation Law of the State of Delaware.

2. The Issuer has the corporate power and corporate authority under the General Corporation Law of the State of Delaware to (i) execute and deliver, and to incur and perform all of its obligations under, each of the Transaction Agreements to which it is a party and (ii) carry on its business and own its properties as described in the Offering Circular.

3. Each of the Transaction Agreements has been duly authorized, executed and delivered by the Issuer.

4. Each of the Indenture and the Registration Rights Agreement constitutes a valid and binding obligation of the Issuer, enforceable against the Issuer in accordance with its terms, under the Applicable Laws of the State of New York.

5. When authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Initial Purchaser in accordance with the Purchase Agreement, the Notes will constitute valid and binding obligations of the Issuer, entitled to the benefits of the Indenture and enforceable against the Issuer in accordance with their terms, under the Applicable Laws of the State of New York.

6. The shares of Common Stock into which the Notes are convertible at the initial conversion price provided in the Indenture have been duly authorized by all necessary corporate action of the Issuer and reserved for issuance upon such conversion and, upon issuance of such shares of Common Stock on conversion of the Notes in accordance with the terms of the Indenture at conversion prices at or in excess of the par value of such shares of Common Stock, will be validly issued, fully paid and nonassessable. There are no preemptive rights to acquire any such shares of Common Stock set forth in the Organizational Documents or in the General Corporation Law of the State of Delaware.

7. Neither (i) the execution and delivery on behalf of, or the incurrence or performance by the Issuer of its obligations under, each of the Transaction Agreements to which it is a party, each in accordance with its terms nor (ii) the offering, issuance, sale and delivery of the Notes pursuant to the Purchase Agreement, (A) constituted, constitutes or will constitute a violation of either of the Organizational Documents, (B) constituted, constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default), under any Applicable Agreement, other than any such breach, violation or default that has been waived, (C) resulted, results or will result in the creation of any security interest in, or lien upon, any of the property or assets of the Issuer pursuant to any Applicable Agreement, (D) resulted, results or will result in any violation of (i) the Applicable Laws of the State of New York, (ii) the Applicable Laws of the United States of America or (iii) Regulation T, U or X of the Board of Governors of the Federal Reserve System, or (E) resulted, results or will result in the contravention of any Applicable Order.

8. No Governmental Approval, that has not been obtained or taken, and is not in full force and effect, is required to authorize any of the Transaction Agreements to which the Issuer is a party on the date hereof, or is otherwise required for (i) the validity of any such Transaction Agreement, (ii) the valid execution and delivery by the Issuer of any such Transaction Agreement, (iii) the incurrence or performance by the Issuer of its obligations thereunder or (iv) the enforceability of any such Transaction Agreement against the Issuer.

9. The statements in the Offering Circular under the caption “United States Federal Income Tax Considerations” insofar as they refer to statements of law or legal conclusions, fairly summarize the matters referred to therein in all material respects, subject to the qualifications and assumptions stated therein.

10. The statements in the Offering Circular under the captions “Description of Capital Stock,” “Description of Certain Indebtedness,” “Description of the Notes” and “Business – Our LNG Receiving

Terminals,” insofar as such statements purport to summarize certain provisions of documents referred to therein and reviewed by us as described above, fairly summarize such provisions in all material respects, subject to the qualifications and assumptions stated therein.

11. Assuming (i) the accuracy of the representations and warranties of the Issuer set forth in paragraphs (gg) and (hh) of Section 2 of the Purchase Agreement, (ii) the due performance by the Issuer and the Initial Purchaser of the covenants and agreements set forth in the Purchase Agreement, (iii) the compliance by the Initial Purchaser with the offering and transfer procedures and the restrictions described in the Offering Circular, (iv) the accuracy of the representations and warranties of the Initial Purchaser set forth in Section 4 of the Purchase Agreement, (v) the accuracy of the representations and warranties made or deemed to be made in accordance with the Purchase Agreement and the Offering Circular by purchasers to whom the Initial Purchaser initially resells Notes, and (vi) that purchasers to whom the Initial Purchaser initially resells the Notes have been made aware of the information set forth in the Offering Circular under the caption “Transfer Restrictions,” (A) the offer, issue, sale and delivery of the Notes to the Initial Purchaser and the initial resale of the Notes by the Initial Purchaser, each in the manner contemplated by the Purchase Agreement and the Offering Circular, and the issuance of shares of Common Stock to holders of the Notes upon conversion thereof in accordance with the terms of the Indenture and the Notes, do not require registration under the Securities Act, and (B) prior to the effectiveness of the Shelf Registration Statement (as defined in the Registration Rights Agreement), such offer, issue, sale and delivery of the Notes and such initial resale of the Notes do not require qualification of the Indenture under the Trust Indenture Act of 1939, as amended; provided, however, that we express no opinion as to any subsequent resale or other transfer of any Notes or any Common Stock.

12. The Issuer is not, and immediately upon completion of the offering of the Notes described in the Offering Circular and the Issuer’s investment of the proceeds of such offering as described in the Offering Circular, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Exhibit B

Opinion of General Counsel

I am of the opinion that, to my knowledge, except as described in the Offering Circular, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending to which the Company or any of its subsidiaries is a party or to which any property of the Company or any of its subsidiaries is the subject which, individually or in the aggregate, if determined adversely to the Company or any of its subsidiaries, would reasonably be expected to have a Material Adverse Effect (as defined in the Purchase Agreement); and to my knowledge, no such investigations, actions, suits or proceedings are threatened or contemplated by any governmental or regulatory authority or threatened by others.

I have participated in conferences with representatives of the Company, with representatives of its independent accountants and with representatives of the Initial Purchaser and their counsel at which conferences the contents of the Offering Circular (including the documents incorporated by reference therein) and related matters were discussed and, although I have not independently verified and am not passing on, and assume no responsibility for, the accuracy, completeness or fairness of the Offering Circular (including the documents incorporated by reference therein) (except as expressly provided above), on the basis of the foregoing (relying with respect to factual matters to the extent I deem appropriate upon statements by officers and other representatives of the Company), no facts have come to my attention to cause me to believe that the Offering Circular (including the documents incorporated by reference therein) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (other than the financial statements, the notes and schedules thereto, and the other financial data included or incorporated by reference therein, as to which I express no statement or belief).

Dear Sirs:

As an inducement to Credit Suisse First Boston LLC (“CSFB”) to execute the Purchase Agreement (the “Purchase Agreement”) with Cheniere Energy, Inc., pursuant to which an offering will be made that is intended to result in the establishment of an orderly market for Convertible Senior Notes Due 2012 (the “Securities”) of Cheniere Energy, Inc., and any successor (by merger or otherwise) thereto, (the “Company”), the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of Common Stock, par value $.003 per share, of the Company (the “Common Stock”) or securities convertible into or exchangeable or exercisable for any shares of Common Stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of shares of Common Stock, whether any such aforementioned transaction is to be settled by delivery of shares of Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of CSFB. In addition, the undersigned agrees that, without the prior written consent of CSFB, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for shares of Common Stock.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and end on and include the date 90 days after the offering date set forth on the final offering circular used to sell the Securities (the “Offering Date”) pursuant to the Purchase Agreement, to which you are or expect to become parties; provided, however, that beginning on the 31^st day after the Offering Date, the undersigned, along with the other executive officers and directors of the Company, may take the actions otherwise prohibited hereby with respect to an aggregate amount of 200,000 shares of Common Stock (the “Allocable Shares”).

The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the term of this Lock-Up Agreement, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company’s Chief Financial Officer or Chief Executive Officer that the Lock-Up Period has expired and that the undersigned has been allocated (in the discretion of the Company) a portion of the Allocable Shares with respect to such action.

Any shares of Common Stock acquired by the undersigned in the open market will not be subject to this Agreement. A transfer of shares of Common Stock or securities convertible into or

exchangeable or exercisable for any shares of Common Stock to a family member or trust may be made, provided the transferee agrees to be bound in writing by the terms of this Agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, shall be required or shall be voluntarily made in connection with such transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period). Notwithstanding anything in this Agreement to the contrary, the undersigned may exercise options outstanding on the date hereof (including cashless exercises thereof); provided, however, that any shares of Common Stock received upon the exercise of options granted to the undersigned (except those sold in order to effect the cashless exercise of options) will also be subject to this Agreement.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock if such transfer would constitute a violation or breach of this Agreement

This Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. The undersigned shall be released from all obligations under this Agreement if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and purchase of the Securities to be sold thereunder. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,

[Name of stockholder]
