11. No Inconsistent Actions. The parties hereto shall not voluntarily undertake or fail to undertake any action or course of action inconsistent with the provisions or essential intent of

6

this Agreement. Furthermore, it is the intent of the parties hereto to act in a fair and reasonable manner with respect to the interpretation and application of the provisions of this Agreement.

12. Construction. This Agreement shall be deemed drafted equally by both the parties. Its language shall be construed as a whole and according to its fair meaning. Any presumption or principle that the language is to be construed against any party shall not apply. The headings in this Agreement are only for convenience and are not intended to affect construction or interpretation. Any references to paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. Also, unless the context clearly indicates to the contrary, (a) the plural includes the singular and the singular includes the plural; (b) “and” and “or” are each used both conjunctively and disjunctively; (c) “any,” “all,” “each,” or “every” means “any and all,” and “each and every”; (d) “includes” and “including” are each “without limitation”; (e) “herein,” “hereof,” “hereunder” and other similar compounds of the word “here” refer to the entire Agreement and not to any particular paragraph, subparagraph, section or subsection; and (f) all pronouns and any variations thereof shall be deemed to refer to the masculine, feminine, neuter, singular or plural as the identity of the entities or persons referred to may require.

13. Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration, conducted before an arbitrator in New York, New York in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitration award in any court having jurisdiction. Only individuals who are (a) lawyers engaged full-time in the practice of law; and (b) on the AAA register of arbitrators shall be selected as an arbitrator. Within 20 days of the conclusion of the arbitration hearing, the arbitrator shall prepare written findings of fact and conclusions of law. It is mutually agreed that the written decision of the arbitrator shall be valid, binding, final and non-appealable, provided however, that the parties hereto agree that the arbitrator shall not be empowered to award punitive damages against any party to such arbitration. The arbitrator shall require the non-prevailing party to pay the arbitrator’s full fees and expenses or, if in the arbitrator’s opinion there is no prevailing party, the arbitrator’s fees and expenses will be borne equally by the parties thereto. In the event action is brought to enforce the provisions of this Agreement pursuant to this Section 13, the non-prevailing parties shall be required to pay the reasonable attorney’s fees and expenses of the prevailing parties, except that if in the opinion of the court or arbitrator deciding such action there is no prevailing party, each party shall pay its own attorney’s fees and expenses.

14. Enforcement. If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.

15. Not a Contract of Employment. Nothing in this Agreement shall confer upon the Executive any right to continue in the employ of the Company or any of its subsidiaries or Affiliates or shall interfere or restrict in any way the rights of the Company or its subsidiaries or Affiliates, which are hereby expressly reserved, to discharge the Executive for any reason whatsoever, with or without Cause, subject to any obligations the Company may have hereunder in connection with a particular Termination of Employment to make severance payments to the Executive pursuant to the terms of this Agreement.

16. Withholding. The Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an opinion of counsel if any questions as to the amount or requirement of withholding shall arise.

17. Executive Acknowledgement. The Executive acknowledges that he has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other than those contained in writing herein, and has entered into this Agreement freely based on his own judgment.

18. Indemnification. The Company shall provide the Executive with indemnification on the same terms as is provided by his indemnification agreements with GG Holdings in effect as of the date hereof, with the Company having all of the obligations and liabilities of GG Holdings thereunder with respect to Executive’s actions as an employee, officer or director of the Company and its Affiliates. The terms of such indemnification agreement are incorporated herein by reference in their entirety; provided that all references to Texas law in such indemnification agreement shall be deemed to references to Delaware law. Such indemnification shall not be exclusive of any other indemnification provided pursuant by law, the by-laws or certificate of incorporation or other organizational documents of the Company or any of its affiliates or otherwise. The Company further agrees that the indemnification provisions set forth in Section 13 of Article III of the Company’s by-laws are incorporated herein by reference and made a part hereof, and any repeal or other modification of such Section of the By-laws or any repeal or modification of the Delaware General Corporation Law or any other applicable law shall not limit Executive’s entitled to the advancement of expenses or indemnification under such Section 13 with respect to any matter occurring during Executive’s employment with the Company, regardless of when the underlying claim may be asserted. The Company shall maintain directors and officers insurance covering Executive as is customary for similarly situated executives at similarly situated companies. The provisions of this Section 18 shall survive the termination of this Severance Agreement. Notwithstanding the foregoing, the Company shall have no indemnification or other obligation to the Executive pursuant to this Section 18 (and the documents incorporated herein) to the extent that satisfaction of such obligation violates any applicable law, rule or regulation. For the avoidance of doubt, nothing in this Section 18 or otherwise shall entitle the Executive to receive any advancement of legal fees or other payments in connection with any dispute as to whether the Executive’s employment was terminated with or without Cause or with or without Good Reason. The parties acknowledge and agree that nothing in this Section 18 shall alter any obligation of the Company pursuant to Sections 2.3(e) and 7.6 of the Asset Purchase Agreement with respect to events occurring on or prior to the Closing Date (as defined in the Asset Purchase Agreement).
