The Reporting Persons have entered into a Joint Filing Agreement, dated October 3, 2011, a copy of which was filed with Amendment No. 2 as Exhibit A (which is hereby incorporated by reference) pursuant to which the Reporting Persons have agreed to file this statement jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Act. Information with respect to each Reporting Person is given solely by each such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information furnished by another Reporting Person.

Pursuant to Rule 13d-4 of the Act, the Reporting Persons expressly declare that the filing of this statement shall not be construed as an admission that any such person is, for the purposes of Section 13(d) and/or Section 13(g) of the Act or otherwise, the beneficial owner of any securities covered by this Amendment No. 4 held by any other person.

Item 3. Source and Amount of Funds or Other Consideration.

Pursuant to the Unit Purchase Agreement between the Issuer and Cheniere Terminals, dated May 14, 2012 (the “CBUH Purchase Agreement”), Cheniere Terminals agreed that it or one of its affiliates would acquire 33,333,334 newly created Class B Units of the Issuer (“Class B Units”) in exchange for $15.00 per unit. The closing of the acquisition of 11,111,111 Class B Units occurred on June 11, 2012 and the closing of the acquisition of the remaining 22,222,223 Class B Units occurred on July 31, 2012. The acquisition was completed by a direct, wholly owned subsidiary of Cheniere Terminals, Cheniere Class B Units Holdings, LLC (“CBUH”). CBUH used available cash obtained pursuant to an intercompany loan among its affiliates to acquire the Class B Units under the CBUH Purchase Agreement.

Earlier purchases of the Issuer’s equity securities by the Reporting Persons are described in the Prior Filings.

Item 4. Purpose of the Transaction.

The Reporting Persons acquired the Common Units reported herein solely for investment purposes. The Reporting Persons may make additional purchases of Common Units either in the open market or in private transactions depending on the Reporting Persons’ business, prospects and financial condition, the market for the Common Units, general economic conditions, stock market conditions and other future developments.

The Reporting Persons and CBUH acquired the Class B Units solely for investment purposes and in connection with a Unit Purchase Agreement among the Issuer, Cheniere Energy and Blackstone CQP Holdco LP (“Purchaser”), dated May 14, 2014 (the “Blackstone Purchase Agreement”) pursuant to which the Purchaser has agreed to acquire 100,000,000 Class B Units in exchange for $1.5 billion in the aggregate (described further below). The Issuer intends to use the net proceeds from the transactions with CBUH and the Purchaser to pay for the construction of two liquefaction trains and related facilities and equipment located in Cameron Parish, Louisiana (the “Liquefaction Facilities”). In connection with the foregoing Class B Unit transactions, Cheniere Energy has agreed to grant to the Purchaser certain rights with respect to the board of directors of Cheniere Energy Partners GP, LLC, a Delaware limited liability company (the “General Partner”) and the general partner of the Issuer (as described below).

The following describes any other plans or proposals that the Reporting Persons may have with respect to the matters set forth in Item 4(a)-(j) of Schedule 13D:

(a) See Item 5 below regarding agreements pertaining to “Additional Class B Units that CBUH may acquire.

(b) None.

(c) None.

(d) See Item 5 below regarding changes to the board of directors of the General Partner.

(e) Cheniere Holdings as owner of the General Partner, Cheniere Terminals as owner of Cheniere Holdings, Cheniere LNG as owner of Cheniere Terminals, and Cheniere Energy as owner of Cheniere LNG, may cause the Issuer to change its distribution policy or its capitalization, through the issuance of debt or equity securities, from time to time in the future.

The Reporting Persons may change their plans or proposals in the future. In determining from time to time whether to sell the Common Units reported as beneficially owned in this Schedule 13D (and in what amounts) or to retain such securities, the Reporting Persons will take into consideration such factors as they deem relevant, including the business and prospects of the Issuer, anticipated future developments concerning the Issuer, existing and anticipated

market conditions from time to time, general economic conditions, regulatory matters, and other opportunities available to the Reporting Persons. The Reporting Persons reserve the right to acquire additional securities of the Issuer in the open market, in privately negotiated transactions (which may be with the Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of the Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.
