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 bonus stock award vests in three equal annual installments beginning on 01/30/2015.
(2) Shares forfeited to meet tax obligation of restricted share vesting.
(3) Common stock acquired as a result of the 2013 performance based unit award vesting and settling at 200% of the target award based on Gastar's share price appreciation over the performance period.
(4) Shares forfeited to meet tax obligation of performance based unit vesting.
(5) Not applicable.
(6) Performance Based Units ("PBUs"): Vesting is ratable over the three year performance period, with settlement in common stock between 0% and 200% (**subject to limitations discussed in Footnote 7 below) of the target award based on Gastar's share price appreciation over a three year performance period relative to a peer index. Share price appreciation is measured generally as the change in market value of common stock during the performance period. The PBUs have no voting rights but provide for dividend equivalents to be paid upon vesting.
(7) The number of PBUs reported (116,379) represents the target award. As such, the number of shares that may be issued upon vesting ranges from 0 shares to 232,758 shares. **As discussed in Footnote 6 above, at the end of the performance period, the participant may earn up to 200% of the target award, subject to a maximum award limitation of one million (1,000,000) shares that may be issued to any individual in a calendar year under the Gastar Exploration Inc. 2006 Long-Term Stock Incentive Plan, as Amended.
