Stockholders Agreement

In connection with the consummation of the Transactions, the Issuer, AR Sub, the WP X O&G Funds, the WP VIII Funds, the Yorktown Entities (the Yorktown Entities together with WP X O&G Funds and the WP VIII Funds, the Sponsors), and Messrs. Rady and Warren (Messrs. Rady and Warren together, the Management Stockholders) entered into a Stockholders Agreement (the Stockholders Agreement), which became effective as of March 12, 2019.

Under the Stockholders Agreement, AR Sub is entitled to nominate two directors, which shall initially be the Management Stockholders, for election to the Board for so long as, together with its affiliates, AR Sub owns at least 8% of the qualifying Shares and one director so long as it owns at least 5% of the qualifying Shares. To the extent that either Mr. Rady and/or Mr. Warren are not designated for election to the Board by AR Sub pursuant to the Stockholders Agreement, the Management Stockholders will be entitled to collectively designate two directors (or one director for so long as either Mr. Rady or Mr. Warren is designated by AR Sub) for election so long as the Management Stockholders and their affiliates (other than Antero Resources and its subsidiaries) collectively own an amount of Shares equal to at least 8% of the qualifying Shares and one director for election for so long as they collectively own an amount of Shares equal to at least 5% of the qualifying Shares. The Sponsors will be entitled to collectively designate two directors for election to the Board for so long as the Sponsors and their affiliates (other than Antero Resources and its subsidiaries) collectively own an amount of Shares equal to at least 8% of the qualifying Shares and one director for election for so long as they collectively own an amount of Shares equal to at least 5% of the qualifying Shares. Notwithstanding the foregoing, upon the occurrence of a Fundamental Change (as defined in the Stockholders Agreement), AR Sub, the Management Stockholders and the Sponsors will each be entitled to designate one director so long as they own an amount of Shares equal to at least 5% of the qualifying Shares, except to the extent that AR Sub designates either Mr. Rady or Mr. Warren, in which case the Management Stockholder will not be entitled to designate a director.

Each of the parties to the Stockholders Agreement have agreed to vote all of their Shares in favor of the directors nominated by the other parties in accordance with the Stockholders Agreement and, at such partys election (i) in favor of any other nominees nominated by the Nominating and Governance Committee of the Board (the Nominating and Governance Committee) or (ii) in proportion to the votes cast by the public stockholders of the Shares in favor of such nominees. In calculating whether the 8% and 5% ownership thresholds are met, the Share ownership for each stockholder or group of stockholders as of the applicable measurement date is divided into (x) the total number of outstanding Shares at the Closing or (y) the total number of outstanding Shares on the applicable measurement date, whichever is less. Pursuant to the terms of the Stockholders Agreement, no more than 45% of the Shares outstanding at the Closing will be subject to the obligations of the Stockholders Agreement.

CUSIP No. 03676B 102

 

Under the Stockholders Agreement, a majority of the Board shall at all times consist of directors who are independent under the listing rules of the New York Stock Exchange and the Act, and who are unaffiliated with the parties to the Stockholders Agreement. Such independent and unaffiliated directors will be nominated for election to the Board by the Nominating and Governance Committee, which will itself consist solely of independent and unaffiliated directors. In addition, under the Stockholders Agreement, the parties have agreed that for so long as AR Sub has the right to designate at least one director, (i) if Mr. Rady is an executive officer of Antero Resources, he shall serve as Chief Executive Officer of the Issuer and (ii) if Mr. Warren is an executive officer of Antero Resources, he shall serve as President of the Issuer, both of which officers shall be subject to removal at the Issuer for cause. For so long as Mr. Rady is a member of the Board and is an executive officer of Antero Resources and/or the Issuer, the parties have agreed that he shall serve as Chairman of the Board, subject to removal at the Issuer for cause. The Stockholders Agreement will terminate as to each stockholder upon the time at which such stockholder no longer has the right to designate an individual for nomination to the Board.

The foregoing description of the Stockholders Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the actual Stockholders Agreement, a copy of which is filed as Exhibit 99.4 hereto and is incorporated by reference in its entirety to this Item 6.

Registration Rights Agreement

In connection with the consummation of the Transactions, the Issuer entered into a Registration Rights Agreement (the Registration Rights Agreement), dated as of March 12, 2019, with certain stockholders, including the WP X O&G Funds, the WP VIII Funds and the Other Persons (collectively, the Registration Rights Holders), pursuant to which the Issuer agreed to register the resale of certain Shares received by the Registration Rights Holders in the Transactions, under certain circumstances, as described below.

Pursuant to the Registration Rights Agreement, the Issuer will use its reasonable best efforts to (i) prepare and file a registration statement under the Securities Act of 1933, as amended (the Securities Act), to permit the resale of the Registrable Securities (as defined in the Registration Rights Agreement) from time to time as permitted by Rule 415 of the Securities Act (or any similar provision adopted by the SEC then in effect) (the Resale Registration Statement) as soon as practicable, but in no event more than 30 days following the Closing and (ii) cause the Resale Registration Statement to become effective no later than 60 days after filing thereof. Except in certain circumstances, Sponsor Holders (as defined in the Registration Rights Agreement) owning at least 3% of the issued and outstanding Shares have the right to require the Issuer to facilitate an underwritten offering. The Issuer is not obligated to effect any demand registration in which the anticipated aggregate offering price included in such offering is less than $50,000,000. Sponsor Holders will also have customary piggyback registration rights to participate in underwritten offerings.

A Registration Rights Holders registration rights will expire at such time that such Registration Rights Holder no longer owns any Registrable Securities.

The foregoing description of the Registration Rights Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the actual Registration Rights Agreement, a copy of which is filed as Exhibit 99.5 hereto and is incorporated by reference in its entirety to this Item 6.

Except as otherwise described herein, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finders fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
