Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. On April 4, 2007, Gastar Exploration Ltd. (the "Company") reported that on March 29, 2007, it had received a warning letter from the American Stock Exchange (the "AMEX") that it was in non-compliance with Section 121(B)(2)(a) of the Amex Company Guide requiring that at least three independent directors serve on the Company's audit committee. The Company had only two independent directors serving on the committee due to the decision of a former director not to stand for reelection at the Company's 2006 Annual Meeting of Shareholders. Until the vacancy is filled, the Audit Committee consists of two independent directors, one of whom is designated as its "financial expert". To satisfy these requirements, the Company notified the AMEX of its intent, as soon as reasonably possible, to fill the vacant Audit Committee position with an individual who satisfies the independence standards, and that a search firm was engaged to assist in that effort. As described below under Item 5.02 of this report, the Board of Directors of the Company has appointed a new director who will satisfy the independence requirements of the AMEX and Rule 10A-3 of the Securities and Exchange Commission and will serve on the Audit Committee, which will bring the Company into compliance with the AMEX Audit Committee membership requirement. Commencing on or about March 30, 2007 until the Company is officially notified that it has regained compliance with the AMEX requirement, the Company's common shares will trade under the symbol "GST.BC". SECTION 5 - CORPORATE GOVERNANCE AND MANAGEMENT Item 5.02. Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers The Company announced that on March 30, 2007 the Board of Directors had appointed John M. Selser Sr. as a member of the Board of Directors and member of the Audit Committee, thus bringing the Company in compliance with the AMEX's audit committee requirements. Mr. Selser will stand for election to the Board of Directors at the Annual Meeting of Shareholders to be held June 1, 2007. Mr. Selser is a partner of Maple Leaf Partners, a Baton Rouge, Louisiana based energy focused hedge fund and has over 20 years of industry experience. He holds a Bachelor of Science in both Civil Engineering and Petroleum Engineering from Louisiana State University, Baton Rouge, Louisiana, and a Masters of Business Administration from Tulane University, New Orleans, Louisiana.
