AMENDMENTS TO BYLAWS

On April 17, 2009, the Company’s Board of Directors voted unanimously to amend Sections 2.5, 2.11 and 2.12 of the Company’s existing Bylaws, as follows:

Section 2.5, Notice of Meeting, was amended to increase the number of days notice within which a notice of meeting of stockholders may be delivered from thirty (30) days to sixty (60) days.

Section 2.11 and 2.12, Fixing of Record Date, were amended to delete the “closing of books” provisions and to fix in advance a date as the record date for any determination or meeting of stockholders, a date not more than ninety calendar days and, in case of a meeting of stockholders, not less than ten business days prior to the date on which the particular action requiring a determination of stockholders is to be taken.

AMENDMENT TO ARTICLES OF INCORPORATION

On June 30, 2006, the Company filed its Certificate of Amendment to Articles of Incorporation to increase the Company’s authorized shares of common stock from 50,000,000 to 200,000,000, pursuant to a stockholder vote by consent, which became effective May 18, 2009. The Company anticipates future efforts to raise additional capital to meet the needs of its oil and natural gas exploration and development activities, as part of its strategic growth plan. Efforts to raise additional funds in the future may involve the issuance of convertible debt, pure equity, or a combination thereof, in one or more transactions.

A change in the authorized capital stock of a Nevada corporation requires an amendment to the Company’s Articles of Incorporation. Nevada Revised Statutes 78.390 requires stockholder approval to amend the Company’s Articles of Incorporation, which may be by stockholders’ consent without a meeting as provided in Nevada Revised Statutes 78.320.

Item 8.01 Other Events.

Each share of Series A Convertible Preferred Stock shall have a stated value equal to $10.00 (as adjusted for any stock dividends, combinations or splits with respect to such shares) and $0.001 par value.
