Explanation of Responses:
1. The securities reported herein were issued pursuant to the reorganization that was completed concurrently with, or prior to, the closing of the initial public offering of common stock ("Common Stock") of Antero Resources Corporation (the "Issuer") described in the prospectus dated October 9, 2013, pursuant to which (i) the existing holders of outstanding membership interests of Antero Resources LLC (the "Units"), received equivalent interests in Antero Resources Investment LLC, a Delaware limited liability company ("Antero Investment"), in exchange for such Units and (ii) Antero Resources LLC merged with the Issuer, with the Issuer being the surviving entity. The Warburg Pincus Entities, (as defined below in footnote 4), collectively hold a 38.4% membership interest, and a minority economic interest that is determined based on a multi-level waterfall, in Antero Investment, which directly owns 220,965,909 shares of the Issuer as of the date hereof.
2. Each of Warburg Pincus Private Equity VIII, L.P., a Delaware limited partnership, ("WP VIII", and together with its two affiliated partnerships Warburg Pincus Netherlands Private Equity VIII C.V. I, a company formed under the laws of the Netherlands ("WP VIII CV I"), and WP-WPVIII Investors, L.P., a Delaware limited partnership, ("WP-WPVIII Investors"), collectively, the "WP VIII Funds"), and other affiliates reporting on a separate Form 4 (see Remarks below) hold a beneficial interest in WP Antero, LLC, a Delaware limited liability company ("WP Antero"), an indirect subsidiary of WP-WPVIII Investors, a direct subsidiary of WP VIII and WP VIII CV I and a member in Antero Investment. (cont'd)
3. WP-WPVIII Investors LLC, a Delaware limited liability company ("WP-WPVIII LLC"), is the general partner of WP-WPVIII Investors. Warburg Pincus Partners LLC, a New York limited liability company ("WP Partners"), is the sole member of WP-WPVIII LLC and the general partner of WP VIII and WP VIII CV I. Warburg Pincus & Co., a New York general partnership ("WP"), is the managing member of WP Partners. (cont'd)
4. Warburg Pincus LLC, a New York limited liability company ("WP LLC"), is the manager of the WP VIII Funds. Charles R. Kaye and Joseph P. Landy are each a Managing General Partner of WP and a Managing Member and Co-President of WP LLC and may be deemed to control the Warburg Pincus Entities. Each of Messrs. Kaye and Landy, together with the WP VIII Funds, WP Antero, WP Partners, WP LLC and WP are collectively referred to herein as the "Warburg Pincus Entities."
5. Each Warburg Pincus Entity disclaims beneficial ownership with respect to any shares of Common Stock, except to the extent of its indirect pecuniary interest in such shares of Common Stock. The WP VIII Funds, WP Antero, WP Partners and WP are directors-by-deputization solely for purposes of Section 16 of the Securities Exchange Act of 1934, as amended. Information with respect to each of the Warburg Pincus Entities is given solely by such Warburg Pincus Entity, and no Warburg Pincus Entity has responsibility for the accuracy or completeness of information supplied by another Warburg Pincus Entity.
6. In connection with the initial public offering (the "IPO") of Common Stock, Antero Resources LLC, a Delaware limited liability company, merged with and into the Issuer, resulting in all of the membership interests in Antero Resources LLC held by Antero Investment immediately prior to the merger being converted into 224,375,000 shares of Common Stock. Pursuant to the exercise by the underwriters of their option to purchase additional shares to cover over-allotments from Antero Investment in connection with the IPO, Antero Investment sold 3,409,091 shares of Common Stock on October 16, 2013.
Remarks:
Due to the limitations on the number of Reporting Persons allowed on Form 4, Warburg Pincus Private Equity X, L.P., a Delaware limited partnership and its affiliates, who are members of WP Antero and may be deemed to hold beneficial ownership in the shares of Common Stock, report such beneficial ownership on a separate Form 4. * The Power of Attorney given by each of Warburg Pincus & Co., Mr. Kaye and Mr. Landy was previously filed with the U.S. Securities & Exchange Commission on January 15, 2013 as an exhibit to a statement on Schedule 13D/A filed by Warburg Pincus Private Equity X, L.P. with respect to Talon Therapeutics, Inc. and is hereby incorporated by reference.
