Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The securities of Energen Corporation (the "Issuer") reported herein were sold on behalf of certain private investment funds for which Corvex Management LP ("Corvex") acts as investment adviser, including Corvex Master Fund LP and Corvex Select Equity Master Fund LP (collectively, the "Corvex Funds"). The general partner of Corvex is controlled by Keith Meister. The American-style call options the expiration of which is reported herein were sold by Corvex on behalf of the Corvex Funds prior to the Reporting Persons becoming subject to Section 16, therefore the expiration of such American-style call options is exempt from Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").
(2) These options were exercisable immediately upon issuance.
(3) For purposes of Section 16 of the Exchange Act, each of Corvex and Mr. Meister disclaims beneficial ownership of any securities of the Issuer held directly by the Corvex Funds except to the extent of their pecuniary interest therein, and this report shall not be deemed an admission that any of Corvex or Mr. Meister are or were the beneficial owner of such securities for purposes of Section 16 or any other purpose.
