Item 1.01               Entry into a Material Definitive Agreement

Effective April 17, 2012, a wholly owned subsidiary of Evolution Petroleum Corporation (the “Company”) entered into definitive agreements with Orion Exploration Partners, LLC (“Orion”) to acquire and develop an undivided 45% interest in oil and gas leases, associated surface rights, and related assets located in the Mississippian Lime formation aggregating 11,700 acres in 38 sections in Kay County, Oklahoma.  The Company has agreed to contribute cash and a drilling carry to earn its 45% non-operating interest.  Orion is contributing the leases, its portion of the drilling capital, its operating expertise in the area and the Mississippian Lime play.

Not including any future leases acquired through forced pooling or other additions, the Company’s initial interests are estimated to have up to 25 to 33 net potential drilling locations, subject to ultimate spacing per horizontal well. The Company estimates drilling, completion and fracturing costs could be approximately $3 million per well, including water disposal facilities. Field operations are expected to commence in May with the drilling of a water disposal well, followed by the scheduled drilling of two producer wells. The agreements commit the parties to drill between six and fourteen wells over the next twelve months.

The material agreements concerning the above transaction are attached hereto as Exhibit 10.1 and Exhibit 10.2, and the foregoing summary is qualified in its entirety by such agreements.
