Mr Crow 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. The company will not name an immediate replacement for Mr Crow but expects to select or nominate a replacement director in 2008.

Russell Porter, chairman, president and CEO of Gastar Exploration, 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.
