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

(a)

Simplification Agreement

On October 9, 2018, the Issuer and Antero Midstream Partners LP, a Delaware limited partnership (“Antero Midstream”), announced that they had entered into a Simplification Agreement (the “Simplification Agreement”), dated as of October 9, 2018, by and among AMGP GP LLC, a Delaware limited liability company and the general partner of the Issuer (“AMGP GP”), the Issuer, Antero IDR Holdings LLC, a Delaware limited liability company and subsidiary of the Issuer (“IDR Holdings”), Arkrose Midstream Preferred Co LLC, a Delaware limited liability company and wholly owned subsidiary of the Issuer (“Preferred Co”), Arkrose Midstream Newco Inc., a Delaware corporation and wholly owned subsidiary of the Issuer (“NewCo”), Arkrose Midstream Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of NewCo (“Merger Sub”), Antero Midstream Partners GP LLC (“AMP GP”), a Delaware limited liability company and the general partner of the Issuer, and Antero Midstream (collectively, the “Parties”).

Pursuant to the Simplification Agreement, the Parties will, on the terms and subject to the satisfaction of certain conditions contained therein, consummate a series of transactions pursuant to which: (1) AMP GP will execute and deliver an amendment (the “Antero Midstream Partnership Agreement Amendment”) to the Agreement of Limited Partnership of Antero Midstream, dated as of November 10, 2014, as amended by Amendment No. 1, dated as of February 23, 2016, and Amendment No. 2, dated as of December 20, 2017 (the “Antero Midstream Partnership Agreement”), pursuant to which, among other things, (i) the “General Partner” as defined in the Antero Midstream

CUSIP No. 03675Y 103

Partnership Agreement shall be permitted to have certain indebtedness, which is intended to permit the GP Merger (as defined below), and (ii) the provisions of the Antero Midstream Partnership Agreement relating to the allocation of gross income relating to distributions paid pursuant to the Simplification Agreement will be modified; (2) at the election of AMP GP, AMP GP will merge with and into the Issuer with the Issuer surviving such merger as the general partner of Antero Midstream (the “GP Merger”); (3) the Issuer will be converted from a limited partnership to a corporation under the laws of the State of Delaware, to be named Antero Midstream Corporation (hereinafter referred to as “New AM”) pursuant to and in accordance with the plan of conversion set forth in the Simplification Agreement (the “Plan of Conversion,” and such conversion, the “Conversion”), each shareholder of the Issuer will receive an equivalent number of shares of New AM Common Stock (as defined below) and a certificate of incorporation of New AM will be adopted and filed with the Delaware Secretary of State and bylaws of New AM will be adopted substantially in the forms attached as exhibits to the Simplification Agreement (the “New AM Organizational Documents”); (4) (i) New AM will (A) contribute up to $120.00 (and in no event less than $100.00) of cash to Preferred Co and (B) issue up to 12,000 shares (and in no event less than 10,000 shares) of Series A Non-Voting Perpetual Preferred Stock, par value $0.01, of New AM (the “New AM Preferred Stock”), to Preferred Co for consideration of $0.01 per share, the terms of which shall be set forth in the Certificate of Designations substantially in the form attached as an exhibit to the Simplification Agreement (the “Certificate of Designations”), and (ii) Preferred Co will transfer such New AM Preferred Stock to The Antero Foundation, a charitable organization, for no consideration (the “Preferred Stock Issuance”); (5) New AM will contribute and assign to NewCo such number of shares of common stock of New AM, par value $0.01 (the “New AM Common Stock”), that is necessary for purposes of effecting the exchange of Series B Units (as defined below) described below (the “Series B Exchange”), together with an additional number of shares of New AM Common Stock necessary to pay the stock portion of the merger consideration as further described below; and (6) Merger Sub will be merged with and into Antero Midstream, with Antero Midstream surviving such merger as a wholly owned subsidiary of NewCo (the “Merger”).

Also on October 9, 2018, pursuant to the Simplification Agreement, the Issuer, in its capacity as the managing member of IDR Holdings, and certain members of management holding a majority of the Series B Units representing limited liability company interests of IDR Holdings (the “Series B Units” and the holders of such Series B Units, the “Series B Holders”), entered into Amendment No. 2 (the “IDR Holdings LLCA Amendment”) to the Limited Liability Company Agreement of IDR Holdings, dated as of December 31, 2016, as amended on May 9, 2018, and as may be further amended. In connection with the Transactions, all of the issued and outstanding Series B Units will be exchanged for an aggregate 17.35 million shares of New AM Common Stock. New AM will enter into a registration rights agreement substantially in the form attached as an exhibit to the IDR Holdings LLCA Amendment (the “Registration Rights Agreement”) with Antero Resources, a Delaware corporation (“Antero Resources”), certain members of management, certain funds affiliated with Warburg Pincus LLC and Yorktown Partners LLC and the Series B Holders (collectively, the “Holders”), to register the resale of the New AM Common Stock issued to the Holders in the Conversion, the Merger and the Series B Exchange, as applicable, under certain circumstances. The transactions contemplated by the Simplification Agreement are collectively referred to herein as the “Transactions.”

The foregoing description of the Simplification Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the actual Simplification Agreement, a copy of which is filed as Exhibit 99.2 hereto and is incorporated by reference in its entirety to this Item 4.

Voting Agreement

On October 9, 2018, concurrently with the execution of the Simplification Agreement, Antero Midstream and the shareholders of the Issuer named in Schedule I thereto (the “Voting Agreement Shareholders”) entered into a Voting Agreement (the “AMLP Voting Agreement”), pursuant to which, subject to the terms and conditions therein, the Voting Agreement Shareholders have agreed to vote (or cause to be voted) all of the Shares beneficially owned by them (the “Covered Shares”) approving the AMGP Shareholder Proposals, and any other matters necessary for consummation of the Merger and the other transactions contemplated in the Simplification Agreement. In addition, the Voting Agreement Shareholders have agreed to vote against the approval or adoption of any action, agreement, transaction or proposal that is intended to or would reasonably be expected to (1) result in a breach of any obligation of the Issuer contained in the Simplification Agreement or (2) to impede, delay, postpone, discourage, frustrate the purposes of or adversely affect any of the Transactions or any action contemplated by the Simplification Agreement.

CUSIP No. 03675Y 103

If, without the prior consent of the Voting Agreement Shareholders, any provisions of the Simplification Agreement described in the next sentence are amended or waived, the obligations of the Voting Agreement Shareholders under the AMLP Voting Agreement shall terminate and the Voting Agreement Shareholders will be deemed to vote against all proposals at the AMLP Unitholder Meeting (as defined in the AMLP Voting Agreement). This termination provision applies only to any such Simplification Agreement amendment or waiver that (i) extends the Termination Date, (ii) adversely impacts the merger consideration to be received by the Voting Agreement Shareholders or the number or value of the Shares held by the Voting Agreement Shareholders upon consummation of the Transactions, or (iii) otherwise has a material adverse effect on the interests of the Voting Agreement Shareholders in the Transactions. As of October 9, 2018, the Reporting Persons collectively owned 55,109,589 Shares, representing approximately 29.6% of the total Shares issued and outstanding. The approval of the Simplification Agreement requires the affirmative vote or consent of holders of a majority of the outstanding Shares and the affirmative vote or consent of unaffiliated holders of Shares that hold a majority of the outstanding Shares.

The foregoing description of the AMLP Voting Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the actual AMLP Voting Agreement, a copy of which is filed as Exhibit 99.3 hereto and is incorporated by reference in its entirety to this Item 4.
