In the second stage of the private placement, which was approved by disinterested shareholders at the Company's annual and special meeting of shareholders held on May 20, 2008, the Company issued an aggregate of 25 million common shares at Cdn $0.36 per share for gross proceeds of Cdn $9.0 million to the Company. The shares were issued to Dalea Partners, LP, an affiliate of Riata, and to certain friends and family of Malone Mitchell 3rd, the head of Riata. Mr. Mitchell and Matthew McCann, the general counsel of Riata, were also elected to the Board of Directors of the Company at the shareholder meeting, and Mr. Mitchell has been appointed by the Board of Directors of the Company to serve as Chairman.

Because the Company repaid the Riata loan prior to June 15, 2008, interest on the loan was waived. The remaining net proceeds from the second stage of the private placement will be used to fund drilling activities in Romania and for general corporate purposes.
