The Company hereby engages Consultant to act as the Company’s Interim Chief Executive Officer (“Interim CEO”), and Consultant hereby accepts such engagement, each subject to and in accordance with the terms and conditions of this Agreement.

The Parties agree that Consultant will perform his services and duties hereunder from his place of residence or at the Company’s principal place of business in San Antonio, Texas; however, the Company expects Consultant to spend as much time as reasonably practicable at the Company’s principal place of business in San Antonio, Texas.

4.Compensation. During the Term, Consultant will be paid base compensation at a rate of $35,000 per month in accordance with the Company’s normal payroll practices.

Further, Consultant acknowledges and agrees that he will not be eligible to participate in or

receive grants or awards under any Company short- or long-term cash or equity incentive compensation plan or program.
