Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 5(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)	Shares of common stock (the "Shares") of Energen Corporation (the "Issuer") held by Vincent J. Intrieri through an entity wholly owned by Mr. Intrieri.
(2)	On January 31, 2018, Corvex Master Fund LP delivered to the Issuer a letter notifying the Issuer of its intent to nominate four persons (the "Corvex Nominees") for election to the Issuer's Board of Directors at the Issuer's 2018 annual meeting of shareholders. Mr. Intrieri is a Corvex Nominee. Corvex Management LP ("Corvex") acts as investment adviser to certain private investment funds, 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. There is no agreement between Corvex and any of its affiliates and Mr. Intrieri with respect to the voting, nor any restriction on the acquisition or disposition, of Shares of the Issuer held by such persons.
(3)	The filing of this statement should not be construed to be an admission that Corvex and any of its affiliates, including the Corvex Funds and Mr. Meister, on the one hand, and Mr. Intrieri on the other hand, are members of a "group" for the purposes of Section 13(d)(3) of the Securities Exchange Act of 1934. Mr. Intrieri has no pecuniary interest in any Shares beneficially owned by Corvex or any of its affiliates and Mr. Intrieri disclaims beneficial ownership of such Shares. Corvex and Mr. Meister are separately filing a joint Form 3.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, See Instruction 6 for procedure.
