The Reporting Persons are:

Each of the Reporting Persons have a business address at c/o RRJ Management (HK) Limited Room 1201-02, 12/F Man Yee Building, 68 Des Voeux Road, Central, Hong Kong.

The Reporting Persons have entered into a Joint Filing Agreement, dated as of the date of this Statement, a copy of which is filed with this Statement as Exhibit 1 (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 Securities Exchange Act of 1934, as amended (the “Act”). Information with respect to each Reporting Person is given solely by such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information furnished by another Reporting Person.

The (i) name, (ii) position, (iii) principal occupation or employment, (iv) name, principal business and address of any corporation in which employment is conducted, and (v) citizenship of each director and executive officer of each of the Reporting Persons are set forth in Schedule A attached hereto.

9 of 16

As previously disclosed by the Issuer, on February 24, 2013, the Issuer entered into a Common Unit Purchase Agreement (the “Purchase Agreement”) with certain purchasers named therein, including Pertin, Bosland, Novolink and Claradon. Pursuant to the Purchase Agreement, Pertin agreed to purchase 1,445,783 Common Units, Bosland agreed to purchase 1,445,783 Common Units, Novolink agreed to purchase 9,638,554 Common Units and Claradon agreed to purchase 2,409,639 Common Units, in each case, subject to the terms and conditions of the Purchase Agreement at a price of $20.75 per Common Unit. This summary of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Purchase Agreement, which is incorporated by reference hereto as Exhibit 99.1.

The Common Units were offered, and the Purchase Agreement entered into, pursuant to a registered direct offering (the “Offering”) by the Issuer. As previously disclosed by the Issuer, the transactions contemplated by the Offering and the Purchase Agreement closed on March 1, 2013.

The funds used to acquire the Common Units directly owned by Pertin, Bosland and Claradon were obtained through contributions to Pertin, Bosland and Claradon by Mr. Ong from his personal funds. The funds used to acquire the Common Units directly owned by Novolink were borrowed from Mr. Ong and Greenwich Asset Holding Ltd. (“Greenwich”). On March 1, Novolink borrowed $92 million from Greenwich, an entity wholly owned by RRJ Master on an interest free basis (the “Greenwich Borrowing”). On March 1, Novolink also borrowed $108 million from Mr. Ong on an interest free basis (the “Ong Borrowing”). The limited partners of RRJ Master are in the process of contributing funds to RRJ Master which in turn is contributing funds to Novolink to repay the Greenwich Borrowing and the Ong Borrowing. The remaining contributions are expected to be received in the next day and then the Greenwich Borrowing and the Ong Borrowing will have been repaid in full and no obligations will remain outstanding.

On March 11, 2013, Claradon, the direct beneficial owner of 2,409,639 Common Units was sold to Ong Tiong Guan, brother of Ong Tiong Sin for $50,000,000 payable on March 11, 2014 plus an additional interest payment of 6% on the $50,000,000 principal (the “Claradon Transaction”) pursuant to the Share Purchase Agreement dated March 11, 2013 between Mr. Ong and Ong Tiong Guan (the “Claradon Purchase Agreement”). At the time of the Claradon Transaction, Ong Tiong Guan was not a director, officer or shareholder of any of the Reporting Persons and the sole asset of Claradon was the 2,409,639 Common Units. This summary of the Claradon Transaction does not purport to be complete and is qualified in its entirety by reference to the Claradon Purchase Agreement, which is incorporated by reference hereto as Exhibit 99.2.

Additionally, on March 11, 2013, Pertin sold 481,928 Common Units though a private sale to Pacific Century Diversified Limited for $10,000,000 (the “Pertin Transaction”).

The Reporting Persons acquired the Common Units to which this Statement relates for investment purposes in the ordinary course of business, and not with the purpose nor with the effect of changing or influencing the control or management of the Issuer. The Reporting Persons have no present plan or proposal that would relate to or would result in: (a) the acquisition by a Reporting Person(s) and/or their affiliates of additional Common Units or other securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present board of directors or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) a material change in the Issuer’s business or structure; (g) changes in the Issuer’s partnership agreement or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer’s securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above. In addition to the Claradon Transaction and the Pertin Transaction the Reporting Persons may make additional dispositions of Common Units in the ordinary course of business.

Notwithstanding the items described in the prior paragraph, depending on various factors including, without limitation, the price levels of the Common Units and other securities of the Issuer, conditions in the securities

10 of 16

markets and general economic and industry conditions, the Reporting Persons and their affiliates may in the future take such actions with respect to the Issuer as they deem appropriate including, without limitation, purchasing additional Common Units of the Issuer or other securities of the Issuer, transferring, selling or otherwise disposing some or all of their Common Units, engaging in hedging or similar transactions with respect to the Common Units or other securities of the Issuer, engaging in discussions with management, the board of directors of the Issuer, other unitholders of the Issuer and other relevant parties, or changing their intention partially or entirely with respect to any or all of the matters described in this Item 4 including taking all or some of the actions specified in the previous paragraph . The foregoing is subject to change at any time, and there can be no assurance that any of the Reporting Persons or their affiliates will take any of the actions set forth above.

(a) and (b) The calculations of percentage ownership in this Statement are based on 57,078,848 Common Units outstanding as set forth in the Prospectus Supplement filed by the Issuer pursuant to Rule 424(b)(2) with the Securities and Exchange Commission on February 25, 2013.

Each Reporting Person’s beneficial ownership has been calculated as indicated below.

11 of 16

(c) See Item 3 disclosure regarding the Claradon Transaction and Pertin Transaction.

(d) None

(e) Not applicable

(1) Mr. Ong, as the sole shareholder and one of three directors of Pertin, may be deemed to have shared voting or dispositive power over the 963,855 Common Units directly held by Pertin. Mr. Ong specifically disclaims beneficial ownership of the Common Units directly held by Pertin, because the board of directors of Pertin which exercises investment discretion for Pertin, also includes 2 additional directors Lam Yan, Managing Director of RRJ Management (HK) Limited and Kim Young So, Managing Partner of Brain Trust Partners. As of March 1, 2013 Pertin was the direct holder of 1,445,783 Common Units and Mr. Ong may have been deemed to have shared voting or dispositive power over the 1,445,783 Common Units, however, after the Pertin Transaction, Pertin’s direct holdings were reduced by 481,928 Common Units and Mr. Ong no longer has shared voting or dispositive power over such Common Units.

(2) Mr. Ong, as the sole shareholder and one of three directors of Bosland, may be deemed to have shared voting or dispositive power over the 1,445,783 Common Units directly held by Bosland. Mr. Ong specifically disclaims beneficial ownership of the Common Units directly held by Bosland, because the board of directors of Bosland which exercises investment discretion for Bosland, also includes 2 additional directors Lam Yan, Managing Director of RRJ Management (HK) Limited and Kim Young So, Managing Partners of Brain Trust Partners.

(3) Claradon is the direct beneficial owner of 2,409,639 Common Units and Mr. Ong, as the sole director and shareholder of Claradon was deemed, after March 1, 2013 to have shared voting or dispositive power over the 2,409,639 Common Units directly held by Claradon. However, after the Claradon Transaction, Mr. Ong is no longer the beneficial owner of the 2,409,639 Common Units.

(4) RRJ Master is the sole shareholder of Novolink and RRJ Capital is the general partner of RRJ Master. RRJ Capital, through its board of directors exercises investment discretion for RRJ Master (and indirectly for Novolink). Therefore each of RRJ Capital, RRJ Master and Novolink are deemed to have shared voting or dispositive power over the 9,638,554 Common Units directly held by Novolink. In addition, as Mr. Ong is the sole shareholder of RRJ Capital and one of 6 directors of RRJ Capital, Mr. Ong may also be deemed to have shared voting or dispositive power over the 9,638,554 Common Units directly held by Novolink. Mr. Ong specifically disclaims beneficial ownership of the Common Units directly held by Novolink, because the board of directors of RRJ Capital which exercises investment discretion for RRJ Master (and indirectly for Novolink), consists of Mr. Ong’s brother and 4 additional directors, as set forth on Schedule A.

(5) As discussed in Items (1)-(4), Mr. Ong (a)(i) had shared voting or dispositive power over the 2,409,639 Common Units directly held by Claradon, and (ii) may have been deemed to have shared voting or dispositive power over 1,445,783 Common Units directly held by Pertin, in each case from March 1, 2011 through the closing of the Claradon Transaction and Pertin Transaction, respectively, on March 11, 2013; and (b) and may be deemed to have shared voting or dispositive power with respect to the (i) 963,855 Common Units held by Pertin, (ii) the 1,445,783 Common Units directly held by Bosland, and (iii) the 9,638,554 Common Units directly held by Novolink. Mr. Ong specifically disclaims beneficial ownership of all the Common Units described in items (1)-(4) except those directly held by Claradon between March 1, 2013 and the closing of the Claradon Transaction on March 11, 2013. From March 1, 2013 through the closing of the Claradon Transaction and Pertin Transaction on March 11, 2013, Mr. Ong shared voting and dispositive power over 14,939,759 Common Units, 26.2% of the Common Units and currently Mr. Ong shares voting and dispositive power over 12,048,192 Common Units, 21.1% of the Common Units.

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) of the Act or otherwise, the beneficial owner of any securities covered by this Statement held by any other person.

Except for the Purchase Agreement, the Claradon Purchase Agreement and the Joint Filing Agreement or as otherwise disclosed herein, including any exhibits hereto, there are no contracts, arrangements, understandings or relationships among the Reporting Persons and any other person with respect to any securities of the Issuer.
