RECITAL

The Company desires to engage Employee’s services, and Employee desires to perform such services, upon the terms, and subject to the conditions, set forth herein.

NOW, THEREFORE, in consideration of the covenants and promises contained herein, the compensation and benefits received by the Employee from the Company and the access given the Employee to the Company’s confidential information and the Company’s customers, and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, and with the Company’s recognition of the knowledge and expertise provided by the Employee being acknowledged, the Company and the Employee hereby agree as follows:

1. Term of Employment.

Subject to the termination provisions set forth herein, the initial term of this Agreement and the Employee’s employment hereunder shall be for a term of two (2) years from the date of this Agreement (the “Initial Term”). This Agreement shall thereafter be automatically extended for additional successive one (1) year terms unless either party gives written notice of termination to the other party not less than ninety (90) days prior to the end of any term (in which event this Agreement shall terminate effective as of the close of the then existing Employment Term). The Initial Term of this Agreement and any additional terms as extended in accordance with this Section 1 are collectively referred to in this Agreement as the “Employment Term.”

2. Position and Duties.

(a) During the Employment Term, the Employee shall serve as President and Chief Executive Officer. The Employee shall have such duties, functions, responsibilities, and authority as are from time to time delegated to the Employee by the Board of Directors of the Company (the “Board”) or are otherwise consistent with the duties, responsibilities and authority of the executive office held by the Employee; provided that with respect to any specifically delegated duties, functions, responsibilities and authority, such duties, functions, responsibilities, and authority are reasonable and customary for a person serving in the office/position of a public company comparable to the Company.

(b) During the Employment Term, the Employee shall: (i) devote substantially all of his time during normal business hours to the business of the Company, fulfill his duties and obligations under this Agreement and use his best efforts, judgment and energy to perform, improve and advance the business and interests of the Company in a manner consistent with the duties of his position; provided, however, that Employee shall not be prevented from serving as a member of the board of directors of a corporation if the Company determines that such membership is not adverse to its interests; (ii) not engage in any business activities that are directly or indirectly competitive with any business conducted by the Company or any of its subsidiaries or affiliates; (iii) observe and carry out such reasonable rules, regulations, policies, directions and restrictions as may be established from time to time by the Board, including but not limited to, the standard policies and procedures of the Company as in effect from time to time; and (iv) do such traveling as may be required in connection with the performance of such duties and responsibilities.

(c) The Employee acknowledges that this Agreement contains a non-disclosure of proprietary information and non-competition provisions, and the Employee agrees to comply with these provisions. The Employee understands that entering into and complying with these provisions is a condition to the Employee’s continued employment with the Company and that failure to comply with the terms of these provisions may result in immediate termination from employment.

(d) In connection with the Employee’s employment by the Company under this Agreement, the Employee shall be based at the principal executive offices of the Company, except for such reasonable travel as the performance of the Employee’s duties in the business of the Company may require. Notwithstanding the foregoing, the Board may, in its discretion, determine to relocate the principal offices of the Company for any necessary business purpose, and doing so shall not be a breach of this Agreement.

3. Hours of Work.

The Employee’s normal days and hours of work shall coincide with the Company’s regular business hours. The nature of the Employee’s employment with the Company requires flexibility in the days and hours that the Employee must work, and may necessitate that the Employee work on other or additional days and hours. The Company reserves the right to require the Employee, and the Employee agrees, to work during other or further days or hours than the Company’s normal business hours.

4. Compensation and Benefits.

(a) Base Salary. During the Employment Term, the Employee shall accrue base salary on a daily basis at a rate equal to $200,000 per year (“Base Salary”) for his services to the Company. All Base Salary shall be paid as set forth in Section 4(f) hereof. The Employee’s Base Salary may be subject to such adjustments as may be determined from time to time by the Board in its sole discretion; provided, however, in no event shall the Employee’s Base Salary be reduced unless such reduction is part of a salary reduction applicable to all similarly situated employees of the Company based upon the Company’s financial condition.

(b) One-Time Sign-on Bonus. The Employee shall receive a one-time, lump-sum, sign-on bonus in the gross amount of $70,000 (the "Sign-On Bonus"), payable in cash upon his signing this Agreement. If the Employee’s employment with the Company ends for any reason prior to March 31, 2009, then the Employee shall immediately repay to the Company the full amount of the Sign-On Bonus.

(c) Stock Options. The Employee shall be eligible to receive awards of options (“Options”) to purchase common stock of the Company (“Common Stock”) pursuant to and in accordance with the terms and conditions set forth in any option plan adopted by the Board in its sole discretion (the “Option Plan”). The decision whether or not to award stock options under the Option Plan, if adopted, to the Employee, and the amount of any such award, shall be within the sole discretion of the Company. The definitive terms and conditions of the Options shall be set forth in a separate option agreement to be entered into by the Employee and the Company (the “Option Agreement”). To the extent there is any inconsistency or conflict between the terms of the Option Agreement and the terms of the Option Plan, the terms of the Option Plan shall govern and control. Upon the execution of this Agreement, the Company shall grant to the Employee options under the Sonterra Resources, Inc. 2007 Non-Qualified Stock Option Plan to acquire shares of Common Stock having an exercise price, vesting and term as described on Exhibit A attached hereto.

(d) Employee Benefits. During the Employment Term, the Employee shall be entitled to participate in all employee benefit plans (including executive bonus plans, cash bonus awards and long-term incentive plans), programs and arrangements that are generally made available by the Company to its senior executives. In addition to the rights of the Employee set forth in the preceding sentence, the Company shall provide health, dental, disability and life insurance for the Employee under such group health, dental, disability and life insurance plans maintained by the Company for its full-time, salaried employees (subject to the terms and conditions thereof). Nothing herein shall require the Company to adopt or maintain any type of benefit plan or policy. The Employee acknowledges that any such plan or policy will be subject to deductibles and co-pay requirements

(e) Expenses. During the Employment Term, the Employee shall be entitled to receive reimbursement upon a timely basis (according to the then-current practices of the Company) for all reasonable and necessary out-of-pocket expenses incurred by the Employee in connection with performing his duties and responsibilities hereunder, that are reimbursable in accordance with the Company’s policies from time to time in effect, upon the presentation by the Employee of an itemized monthly accounting of such expenditures, including receipts where required by Company policy or federal income tax regulations.

(f) Payment of Base Salary. No Base Salary shall be paid to the Employee prior to the Acquisition Completion. Promptly after the Acquisition Completion, but no earlier than three Business Days, and no later than five Business Days, after the public announcement of the Acquisition Completion, the Company shall pay the Employee all Base Salary accrued through such payment date. Base Salary for the periods after such payment date shall be payable in installments in accordance with the general payroll practices of the Company, or as otherwise mutually agreed upon, but no less often than twice monthly. As used in this Agreement, “Business Day” means any day other than Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to remain closed.

(b) Without Cause. The Company may in its sole and absolute discretion terminate Employee’s employment hereunder at any time without Cause for any or no reason.

For purposes of this Agreement, the “Disability” of the Employee shall be deemed to have occurred at such time as the Board determines, in its reasonable discretion, (i) that despite any reasonable accommodation required by law, the Employee is unable to perform the essential functions of his position hereunder as a result of his physical or mental incapacity and (ii) that such inability has existed or is likely to exist for a period of ninety (90) days or more in any twelve (12) month period or for sixty (60) consecutive days.

(e) Termination By The Employee.

For Good Reason.

For purposes of this Agreement, a “Good Reason Termination” shall mean a termination by the Employee of Employee’s employment hereunder pursuant to this Section 6(e).

(f) Notice of Termination. Any termination of the Employee’s employment hereunder by the Company or by the Employee (other than a termination pursuant to Section 6(c)) shall be communicated by a Notice of Termination (as defined below) to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a written notice which (i) indicates the specific termination provision in this Agreement relied upon, (ii) in the case of a termination for Disability or a For Cause Termination or a Good Reason Termination, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Employee’s employment under the provision so indicated, and (iii) specifies the Employment Termination Date (as defined in Section 6(g) below). The failure by the Company or Employee, as applicable, to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Disability, Cause or Good Reason shall not waive any right of the Company or Employee hereunder or preclude the Company or Employee from asserting such fact or circumstance in enforcing the Company’s or Employee’s rights hereunder.

In addition, the Employee shall execute, verify and deliver assignments of such Proprietary Rights to the Company or its designee. The Employee’s obligation to assist the Company with respect to Proprietary Rights relating to such Company Inventions in any and all countries shall continue beyond the termination of employment, and the Company shall provide compensation at a reasonable rate after termination for the time actually spent by the Employee at the Company’s request on any such assistance.

11. Non-Competition.

(a) Employee will, as a result of his employment with the Company, be involved with and exposed to substantial business resources and assets of the Company and certain of its affiliates and will develop additional contacts and relationships with numerous individuals and companies, which are also involved in the business of the Company or businesses related thereto. Such individuals and organizations will have business and contractual relationships with the Company and/or its affiliates that will be a valuable asset thereof. The Employee also recognizes and agrees with the Company that the services which the Employee will render during the Employment Term are unique, special and of extraordinary character, that the Company will be substantially dependent upon such services to develop and market its products and to earn a profit, and that the application of the Employee’s knowledge and services to any competitive business would be substantially detrimental to the Company. Accordingly, in consideration for employment by the Company and compensation and other benefits, including any compensation the Employee may receive after his employment is terminated pursuant to this Agreement, the Employee shall not, directly or indirectly (whether as an employee, officer, executive, director, manager, stockholder, member, lender, consultant or any other capacity), during the period of his employment with the Company, and for a period of six (6) months after termination of employment hereunder for any reason whatsoever, engage in any business or activity or otherwise compete anywhere in the United States, with any business or activity that is competitive with any business or activity engaged in by the Company or any of its subsidiaries or affiliates or contemplated to be engaged in (as of the time of the termination of employment) by the Company or any such subsidiary or affiliate; provided, however, that the foregoing sentence shall not be applicable in the event the Employee is terminated pursuant to Section 6(e)(ii) hereof or if the Employee or the Company terminates this Agreement at the end of the Initial Term or any additional term pursuant to Section 1. In addition, for a period of two (2) years from the end of the Employment Term the Employee shall not induce or attempt to induce any person or entity that is engaged in any business activity or relationship with the Company or any subsidiary or affiliate of the Company to terminate that activity or relationship to reduce such activity or relationship.

(b) The term “compete” as used herein means to engage, directly or indirectly, either as a proprietor, partner, employee, commissioned salesperson, agent, consultant, director, officer, stockholder or in any other capacity or manner whatsoever. The provisions of this Section shall not prevent the Employee from investing any assets in securities of any publicly-traded corporation, provided that such investments do not, directly or indirectly, result in the Employee, his spouse or his children collectively (i) owning beneficially at any time five percent (5%) or more of the equity securities of any corporation engaged in a business competitive with the Company, or (ii) otherwise being able to control or actively participate in the business decisions of such corporation.

12. Non-Solicitation.

For the period of his employment by the Company and for two (2) years after the date of the conclusion of such employment, the Employee shall not (i) induce, solicit or seek to influence, either directly or indirectly, any employee of, or any person under written contract with, the Company or any of its affiliates, to leave the employ of the Company or any subsidiary, or division thereof or to enter into any employment agreement, independent contractor arrangement, or any other arrangement whereby such individual would perform services for compensation, either directly or indirectly, for any person, firm, corporation or other entity engaged in business in competition with the Company or any of its affiliates, or (ii) solicit any customer of the Company or any of its affiliates, or any identified prospect or identified potential customer to which a marketing proposal or presentation was made during the twelve-month period immediately preceding termination of the Employment Term (other than on behalf of the Company) for any business of the type conducted by the Company.

13. No Conflicting Obligations.

The Employee represents and warrants that the Employee has the full right and authority to enter into this Agreement and to render the services as required under this Agreement, and that the execution, delivery, and performance by the Employee of this Agreement do not and will not conflict with or result in a violation of any provision of, or constitute a default under, any contract, agreement, instrument, or obligation to which the Employee is a party or by which the Employee is bound, including any agreement to keep in confidence information acquired by the Employee in confidence or in trust prior to employment by the Company. The Employee shall not enter into any agreement or business relationship or incur any obligations to any third party following the date hereof that may conflict with, or interfere with the Employee’s abilities to perform, the Employees duties and responsibilities pursuant to this Agreement.

The Employee further agrees that any property situated on the Company’s premises and owned by the Company, including computer disks and other digital, analog or hard copy storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice.

19. Miscellaneous.

(a) Telephones, stationery, postage, e-mail, the internet and other resources made available to the Employee by the Company are solely for the furtherance of the Company business.

(b) All construction and interpretation of this Agreement shall be governed by and construed in accord with the internal laws of the State of Texas, without giving effect to that State’s principles of conflicts of law.

(c) The Employee and the Company agree that any provision of this Agreement deemed unenforceable or invalid by any court of competent jurisdiction shall be reformed and modified to make such provision valid and to permit enforcement of the objectionable provision to the fullest permissible extent. It is the intent of the Company and the Employee that this Agreement be enforced to the fullest extent permitted by applicable law. Any provision of this Agreement deemed unenforceable after modification shall be deemed stricken from this Agreement, with the remainder of this Agreement being given its full force and effect. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms, provisions and conditions of this Agreement shall nevertheless remain in full force and effect.

(d) Any waiver granted by a party of any breach of or failure to comply with any provision or condition of this Agreement by the other party shall not be construed as, or constitute, a continuing waiver of such provision or condition, or a waiver of any other breach of, or failure to comply with, any other provision or condition of this Agreement, any such waiver to be limited to the specific matter and instance for which it is given. No waiver of any such breach or failure or of any provision or condition of this Agreement shall be effective unless in a written instrument signed by the party granting the waiver.

(e) The Employee and the Company independently have made all inquiries regarding the qualifications and business affairs of the other which either party deems necessary.

The Employee further affirms that, prior to assenting to the terms of this Agreement, the Employee had been provided with a reasonable time to review it, consult with counsel of the Employee’s own choice, and to negotiate at arm’s length with the Company as to the contents of this Agreement. The Employee further affirms that the provisions in this Agreement represent accurately the expression of the parties’ mutual intent, and that the Employee has entered into this Agreement freely and voluntarily and without pressure or coercion from anyone. Each party assumes the risk of any misrepresentation or mistaken understanding or belief relied upon by either party in entering into this Agreement. In resolving any dispute or construing any term or provision in this Agreement, there shall be no presumption made or inference drawn because of the inclusion of a provision not contained in a prior draft or the deletion of a provision contained in a prior draft. The parties acknowledge and agree that this Agreement was negotiated and drafted with each party being represented by competent counsel of its choice and with each party having an opportunity to participate in the drafting of the provisions hereof and shall therefore be construed as if drafted jointly by the parties.

(f) The Company and the Employee agree that the Employee’s obligations to the Company during the Employee’s employment with the Company, as well as any other obligations of the Employee under this Agreement, may be assigned to any successor in interest to the Company or to any division or affiliate of the Company in its sole discretion and without additional consideration or prior notice to the Employee, but that nothing requires the Company to do so. The Employee’s obligations under this Agreement are personal in nature and may not be assigned by the Employee to any other person or entity.

(g) This Agreement contains the entire understanding and agreement of the parties relating to the subject matter hereof and supersedes all prior and/or contemporaneous understandings and agreements of any kind and nature (whether written or oral) among the parties with respect to such subject matter, all of which are merged herein. This Agreement may not be modified, amended, altered or supplemented, except by a written agreement executed by each of the parties hereto.

(h) This Agreement and any amendments hereto may be executed and delivered in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement, and shall become effective when counterparts have been signed by each party hereto and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. In the event that any signature to this Agreement or any amendment hereto is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. At the request of any party, each other party shall promptly re-execute an original form of this Agreement or any amendment hereto and deliver the same to the other party. No party hereto shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that such signature was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation or enforceability of a contract, and each party hereto forever waives any such defense.

(i) The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.
