On July 25, 2008, Gastar Exploration, Ltd, Gastar Exploration USA, Inc., f/k/a First Sourcenergy Wyoming, Inc. (together, “Gastar”), J. Russell Porter, Gastar’s Chairman and Chief Executive Officer, (“Porter”) entered into a First Amendment to Porter’s Employment Agreement effective March 23, 2005 (the “Porter Amendment”). On the same date, Gastar and Michael A. Gerlich, Gastar’s Chief Financial Officer, (“Gerlich”) entered into a First Amendment to Gerlich’s Employment Agreement effective April 26, 2005 (the “Gerlich Amendment” and together with the Porter Amendment, the “Amendments”). The Amendments bring each Employment Agreement into compliance with the applicable provisions of Section 409A of the Internal Revenue Code of 1986, as amended, and Treasury regulations, thus providing consistency between the amount paid to each of Porter and Gerlich and the tax treatment of severance payments made in the event of (1) termination of either Porter or Gerlich by the Company and (2) termination resulting from change of control. Additionally, the Amendments make certain clarifications to the provisions of Porter’s and Gerlich’s Employment Agreements including:

• Increasing Porter’s severance payment to 4.5 times his annual salary, rather than 3.0 times his annual salary plus bonus (resulting in no change in the total amount that would be paid to Porter);

• Increasing Gerlich’s severance payment to 2.5 times the sum of his annual salary plus a target bonus of 35% of such amount (to provide consistency between the Gerlich Agreement and the provisions of severance resulting from a change of control);

• Removing stock option vesting acceleration should Porter voluntarily terminate his Employment Agreement;

• Specifying the timing of any bonus payable to Porter and Gerlich; and

• Other administration compliance changes.

A copy of each of the Amendments is attached hereto as Exhibit 10.1 and Exhibit 10.2.
