Items 3.01 and 8.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing; Other Events.

As previously disclosed in a Current Report on Form 8-K filed July 5, 2012, GeoPetro Resources Company (the “Company”) received notice from the NYSE MKT LLC (the “Exchange”) on June 28, 2012, indicating that the Company did not satisfy the continued listing standards of the Exchange set forth in Section 1003(a)(iv) of the NYSE MKT LLC Company Guide (the “Company Guide”), which applies if a listed company has sustained losses which are so substantial in relation to its overall operations or its existing financial resources, or its financial condition has become so impaired that it appears questionable, in the opinion of the Exchange, as to whether the Company will be able to continue operations and/or meet its obligations as they mature. In order to maintain its listing, the Company was required to submit a plan addressing how it intended to regain compliance with Section 1003(a)(iv) of the Company Guide by July 30, 2012. The Company provided the Exchange with a plan on July 30, 2012 (the “Plan”). On August 27, 2012, the Exchange notified the Company that it accepted the Plan and granted the Company until September 28, 2012 to regain compliance with the continued listing standards (the “Plan Period”). Furthermore, on October 9, 2012, the Exchange notified the Company that it had determined that, in accordance with Section 1009 of the Company Guide, the Company made a reasonable demonstration of its ability to regain compliance with Section 1003(a)(iv) of the Company Guide by December 31, 2012, through which date the Exchange extended the Plan Period.

On April 10, 2013, the Company received notice from the Exchange indicating that after a review of the Plan, and the request by the Company to extend the Plan Period until July 31, 2013, the Exchange determined that the Company has not made sufficient progress consistent with the Plan in order to regain compliance with Section 1003(a)(iv) of the Company Guide by July 31, 2013 and that its securities are, therefore, subject to being delisted from the Exchange. In the April 10, 2013 notice, the Exchange also informed the Company that, in accordance with Sections 1203 and 1009(d) of the Company Guide, the Company has a right to appeal the Exchange’s determination by requesting an oral hearing or a hearing based on a written submission before the Exchange’s Listing Qualifications Panel (the “Panel”).

The Company intends to appeal the Exchange’s determination by requesting an oral hearing before the Panel, which request will stay the delisting determination until at least such time as the Panel renders a determination following the hearing. The Company anticipates that the hearing will take place in approximately six (6) to eight (8) weeks time. The Company is undertaking steps to address the deficiencies raised by the Exchange. However, there can be no assurance that the Company will be successful in its appeal and that the Company’s request for continued listing will be granted. Receipt of the aforementioned notice from the Exchange, and the delisting or potential delisting of the Company’s securities by the Exchange, will not affect the proposed merger of the Company with a wholly owned subsidiary of MCW Energy Group Limited (previously announced), though no assurance can be given that the conditions to the merger will be either satisfied or waived.

Further, as previously disclosed in a Current Report on Form 8-K filed November 28, 2012, the Company received notice from the Exchange on November 21, 2012, indicating that the Company did not satisfy the continued listing standards of the Exchange set forth in Section 1003(f)(v) of the Company Guide because the Company’s common stock had traded at a low price per share for a substantial period of time. In that notice, the Exchange predicated the Company’s continued listing on the Exchange on the Company effecting a reverse stock split of its common stock by May 21, 2013.
