Yorktown VIII Associates LLC, Yorktown Energy Partners IX, L.P., Yorktown IX Associates LLC, Yorktown Energy Partners X, L.P., and Yorktown X Associates LLC (the "Other Filers") are also reporting persons. Since the SEC's filing system will not accept CIK and CCC codes from more than ten joint filers of a report, the Other Filers have filed a separate Form 3 that relates to the same securities reported herein. Thus, in total, there are 15 joint filers: the Other Filers and each person that is a signatory to this Form 3.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
