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)	Includes 0.0676 shares acquired pursuant to dividend reinvestment and previously not reported pursuant to Rule 16a-11.
(2)	The amount originally reported in this row reflected shares issued on July 1, 2011 in the context of the spin-off of Issuer from Marathon Oil Corporation on June 30, 2011 (the "Spin-Off") and reflected a rounding error, which resulted in an over-reporting by 0.001 share. The amount currently reflected in this row corrects such number of fractional shares.
(3)	Includes 6.8380 shares acquired pursuant to dividend reinvestment and previously not reported pursuant to Rule 16a-11.
(4)	Vests in annual installments of 1,799 shares on December 5, 2012, 1,799 shares on December 5, 2013 and 1,800 shares on December 5, 2014.
