This Technology Assignment Agreement (“Agreement”) is executed on this the 2nd day of August, 2011 by and between Evolution Petroleum Corporation, a Nevada corporation whose address is 2500 CityWest Blvd, Suite 1300, Houston, Texas 77042 (hereinafter referred to as “EPC”) and Daryl Mazzanti, whose address is 18434 Bivens Bend Spring, Texas 77379 (hereinafter referred to as “Mazzanti”). EPC and Mazzanti may be referred to collectively in this Agreement as “Parties,” or individually as a “Party.”

WHEREAS, Mazzanti, prior to his employment with EPC (formerly known as Natural Gas Systems, Inc.) and independent of any prior employer, developed certain technology and procedures to enhance oil and gas production in horizontal well bores;

WHEREAS, as part of Mazzanti’s employment agreement with EPC, EPC agreed to field test and potentially commercialize the technology and procedures so developed by Mazzanti;

WHEREAS, EPC desires to acquire all of Mazzanti’s right, title and interest in, to and under the technology and procedures, and Mazzanti desires to sell, assign, transfer and convey the same to EPC pursuant to the terms and conditions set forth herein;

NOW, THEREFORE, for and in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by all Parties, EPC and Mazzanti hereby agree as follows:

1.           Assignment of the Technology. Upon the execution of this Agreement by the Parties, Mazzanti does hereby assign, transfer and convey unto EPC all of Mazzanti’s right, title and interest in and to that certain technology, invention, design, improvement, or any related intellectual property known as the Gas Assisted Downhole Pump, which is more fully described on Exhibit A, which is attached hereto and incorporated herein by reference (hereinafter referred to as the “Technology”).

2.           Potential Patents of Technology. EPC shall, at its sole cost and expense, undertake the necessary legal and technical review of the Technology to determine if any aspect of the Technology is patentable. In the event that EPC determines, in its sole and unfettered discretion, that any aspect of the Technology is deemed patentable and in its business judgment is commercially viable, EPC shall initiate and carry through actions commercially and reasonably necessary to patent the Technology in the United States and such other foreign countries that EPC deems appropriate. The Parties stipulate and agree that the Technology shall, in the absence of any patent filings relating to the Technology, or, in the event of any such patent filings but prior to any publication or other public dissemination of the subject matter disclosed therein, be deemed a trade secret of EPC, Mazzanti shall in any event timely assign all such patents or patent applications to EPC whenever reasonably requested.

3.           Field Testing of Technology. EPC shall, at its sole cost and expense, make commercially reasonable efforts to field test the Technology. All aspects (including without limiting the generality of the foregoing, direction, control, number of tests, duration, location and cost) of any such field testing of the Technology shall be at the sole and unfettered discretion of EPC.

4.           Assistance by Mazzanti. Mazzanti shall fully cooperate and assist EPC in the prosecution of any patent application(s) of the Technology by EPC. Additionally, Mazzanti agrees to provide EPC with all know-how and necessary technical support for the field testing of the Technology. The cooperation and assistance of Mazzanti in the patent application process and in the field testing of the Technology shall in no manner adversely effect his employment obligations with EPC, without the express written consent of EPC.

5.           Compensation. EPC shall pay to Mazzanti the amount of $5,000.00 per well for every successful application of the Technology by EPC or through EPC’s control (the “Technology Fee”), as adjusted on the annual anniversary date of this agreement by the respective change in the U.S. Consumer Price Index. Amounts so paid shall be less any applicable required tax. However, no Technology Fee shall be due to Mazzanti for installations of the Technology that are primarily for reasonable field tests of the Technology in EPC owned wells, or for up to two demonstrations of the Technology for a third party in which, as an inducement to that third party to field test the Technology in consideration of commercially applying the Technology to a portfolio of wells, EPC does not receive any revenue, net of installation cost of the Technology and well operating cost. Mazzanti shall have the right, but not the obligation, to have an independent certified public accountant inspect and audit the relevant books and records of EPC to verify the statements and payments required to be made pursuant to this Agreement. Any such inspection and/or audit shall be conducted during the normal business hours of EPC and in such a manner that will result in minimum inconvenience to EPC. The cost and expense of any such inspection and/or audit shall be borne by Mazzanti Any such inspection and/or audit shall be conducted no more than once a year without the express written consent of EPC.

6.           Sale or Transfer of Technology. In the event that EPC sells, transfers or conveys the Technology, rights to the Technology or any patents derived from the Technology (collectively referred to hereinafter as the “Related Technology”) to any Person or Entity, other than an Affiliate of EPC, such sale shall be subject to the buyer assuming the obligations of EPC under this Agreement. For the purposes of the Agreement, “Affiliate” means any person, company or entity controlling, controlled by or under common control with any other person, company or entity. For purposes of this definition, “control” (including “controlled by” and “under common control with”) means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such person, company or entity, whether through the ownership of voting securities or otherwise.

7.           Representations and Warranties by Mazzanti. Mazzanti represents, warrants and covenants to EPC that no assignment, grant, mortgage, license or any other contractual agreement affecting the rights to the Technology has been made to any other person or entity, and that the full right to sell, assign, transfer and convey the Technology as described herein is possessed solely by Mazzanti (except as indicated in Section  10.4 infra); and, when requested to
