Section 1.3. Other Agreements. At the Closing, each Stockholder shall execute and deliver agreements not to compete substantially identical in form to Exhibit 1.3(a) (the “NonCompete Agreements.”)

Section 1.4. Closing.

(a) The closing (the “Closing”) of the transaction contemplated by this Agreement (the “Transaction”) shall take place at Sooner’s office on August 31, 2007, or the first subsequent date on which the last of the conditions set forth in Article V is fulfilled or waived, or at such other time and place as Buyer and the Stockholders shall agree in writing.

The party not conducting the defense will use reasonable efforts to assist in the vigorous defense of any such matter, provided that such party shall not be liable for any settlement of any claim reached without its written consent, which consent shall not be unreasonably withheld. Any indemnified party wishing to claim indemnification under this Article VII, upon learning of any such claim, action, suit, proceeding or investigation, shall notify the indemnifying party (but the failure so to notify a party shall not relieve such party from any liability which it may have under this Article VII except to the extent such failure materially prejudices such party). If the indemnifying party is responsible for the attorneys’ fees of more than one indemnified party, then the indemnified parties as a group may retain only one law firm to represent them with respect to each such matter unless there is, under applicable standards of professional conduct, a conflict on any issue between the positions of any two or more indemnified parties.

(a) The Stockholders shall have the right to terminate this Agreement:

(i) if the representations and warranties of Buyer fail to be true and correct in all material respects (or in all respects in the case of any representation or warranty containing any materiality qualification) on and as of the date made and as of the Closing Date and such failure shall not have been cured in all material respects (or in all respects in the case of any representation or warranty containing any materiality qualification) within 30 days after written notice of such failure is given to Buyer by the Stockholders;

(ii) if the Transaction is not completed by August 31, 2007 (provided that the right to terminate this Agreement under this Section 8.1(a)(ii) shall not be available to the Stockholders if the failure of the SES or the Stockholders to fulfill any obligation to Buyer under or in connection with this Agreement is the cause of or resulted in the failure of the Transaction to occur on or before such date);

(iii) if Buyer (A) fails to perform in any respects any of Buyer’s covenants in this Agreement, and (B) does not cure such default in all material respects (or in all respects in the case of any covenant containing any materiality qualification) within 30 days after written notice of such default is given to Buyer by the Stockholders.

13

(b) Buyer shall have the right to terminate this Agreement:

(ii) if the Transaction is not completed by August 31, 2007 (provided that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to Buyer if the failure of Buyer to fulfill any obligation to SES or the Stockholders under or in connection with this Agreement has been the cause of or resulted in the failure of the Transaction to occur on or before such date); or

(iii) if SES or the Stockholders (A) fail to perform in any material respect (or in all respects in the case of any covenant containing any materiality qualification) any of SES’s or Stockholders’ covenants in this Agreement and (B) do not cure such default in all material respects (or in all respects in the case of any covenant containing any materiality qualification) within 30 days after notice of such default is given to the Stockholders by Buyer.

Section 8.2. Effect of Termination. In the event of termination of this Agreement by either Buyer or the Stockholders pursuant to the provisions of Section 8.1, this Agreement shall forthwith become void, and there shall be no further obligations on the part of SES, Stockholders or Buyer or their respective officers or directors (except as set forth in this Section 8.2 and in Sections 5.3, 8.3, 8.9, 8.10 and 8.15, all of which shall survive the termination). Nothing in this Section 8.2 shall relieve any party from liability for any breach of this Agreement.

Section 8.3. Remedies. If any legal action or other proceeding is brought for the enforcement of this Agreement, or because of an alleged dispute, breach, default or misrepresentation in connection with any of the provisions of this Agreement, the successful or prevailing party or parties shall be entitled to recover reasonable attorneys’ fees and all costs incurred in that action or proceeding in addition to any other relief to which it may be entitled at law or equity.

Section 8.6. Severability. In the event that any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement.

Section 8.7. Section Headings. The section headings used herein are descriptive only and shall have no legal force or effect whatsoever. Except to the extent the context specifically indicates otherwise, all references to articles, schedules, exhibits and sections refer to articles schedules, exhibits and sections of this Agreement.

The parties hereto agree that the Transaction has a reasonable relation to the State of Texas because the corporate headquarters of Buyer is located in Texas.

15

Section 8.10. Multiple Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original.

Section 8.11. Waiver. Any waiver by either party must be in writing to be enforceable, and no waiver by either party shall constitute a continuing waiver.

In the event that the Transaction is not Closed or consummated Buyer shall cause all persons and entities in possession of Confidential Material to promptly return all written and electronic Confidential Material and copies thereof furnished to it by the party originally providing the Confidential Material. Except as otherwise required by law, the Buyer, its officers, directors, employees, attorneys, accountants, agents and representatives, shall keep the Confidential Material confidential, not use the Confidential Material for any purpose other than to the extent contemplated by this Agreement, or permit any such Confidential Material to be made available to third parties other than Buyer’s designated representatives or agents whom the Buyer shall direct to maintain the Confidential Material confidential. Confidential Material may be disclosed to the extent required in the course of inspections or inquiries by any federal or state regulatory agency to whose jurisdiction the parties are subject and that have the legal right to inspect the files that contain the Confidential Material. The obligations of the Buyer and its officers, directors, employees, attorneys, accountants, agents and representatives under the provisions of this Section 8.15 shall expire upon the earlier of the Closing or five (5) years after the date of this Agreement.
