     Gastar Announces Resignation of Thomas L. Crow, as Director


    HOUSTON--(BUSINESS WIRE)--Dec. 13, 2007--Gastar Exploration Ltd.
(AMEX:GST) and (TSX:YGA) (the "Company") announced that Thomas L. Crow
had advised the Company's Board of Directors that he will resign from
the Board of Directors effective January 1, 2008 for family health
reasons. Mr. Crow, age 76, has served as a director of Gastar since
April 2002, and is a member of the Governance, Audit, Reserve,
Remuneration and Nomination Committees of the Board of Directors.
There have been no disagreements or disputes between Mr. Crow and the
Company that led to his resignation. The Company will not name an
immediate replacement for Mr. Crow but expects to select or nominate a
replacement director in 2008.

    J. Russell Porter, Gastar's Chairman, President and CEO, in
commenting on Mr. Crow's resignation said, "Mr. Crow has been a
director of the Company since 2002 and has been one of our most active
and supportive directors during that time. His long term interest in
Gastar and active participation on the Board of Directors has
significantly benefited the Company. Mr. Crow's knowledge of the
Australian business market has been particularly beneficial to Gastar
as we have built an asset base in Southeastern Australia. He is highly
respected by all of us at Gastar and will be greatly missed."

    Mr. Crow commented, "My decision to resign from the Board of
Gastar is based solely upon personal and family reasons, and I have no
intention of selling my Gastar shares. It has been a pleasure to work
with Gastar and the other Board members over the past five years. I am
proud to have been part of the Company's progress and growth and wish
the Company, its management and employees continued success in the
future."
