1.3. Instruction Letter. The Company agrees to submit an instruction letter substantially in the form attached hereto as Exhibit A to its transfer agent to effect the Preferred Unit Exchange on the Closing Date.

2. GENERAL PROVISIONS.

2.1. Successors and Assigns. Except as otherwise provided in this Agreement, this Agreement, and the rights and obligations of the parties hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives; provided that such party consents in writing to be bound by the terms, conditions and obligations under this Agreement.

2.2. Governing Law; Submission to Jurisdiction; Consent to Service of Process.

(a) This Agreement is governed by and will be construed in accordance with the Laws of the State of Texas without giving effect to any choice or conflict of Law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Texas.

(b) All actions, suits or proceedings arising out of or relating to this Agreement, any of the other Transaction Documents or the consummation of the Transactions shall be heard and determined exclusively in the First Business Court Division of the State of Texas located in Dallas, Texas (the “Texas Business Court”) or, if such court does not have jurisdiction, any federal court sitting in the State of Texas. Consistent with the preceding sentence, the parties hereby (i) irrevocably submit to the exclusive jurisdiction of the Texas Business Court and federal courts located in Texas (and of the appropriate appellate courts therefrom) for the purpose of any action, suit or proceeding Texas out of or relating to this Agreement; (ii) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such action, suit, or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the action, suit or proceeding is brought in an inconvenient forum, that the venue of the action, suit or proceeding is improper, or that this Agreement may not be enforced in or by any of the above-named courts; and (iii) irrevocably consent to and grant any such court exclusive jurisdiction over the person of such parties and over the subject matter of such action, suit or proceeding and agree that mailing of process or other papers in connection with any such action, suit or proceeding in the manner provided in Section 2.4.

2.5. Amendments and Waivers. This Agreement can be amended, supplemented, or changed, and any provision hereof can be waived, only by written instrument making specific reference to this Agreement signed by the Party against whom enforcement of any such amendment, supplement, modification, or waiver is sought. No action taken pursuant to this Agreement, including any investigation by or on behalf of any Party, shall be deemed to constitute a waiver by the Party taking such action of compliance with any representation, warranty, covenant, or agreement contained herein. The waiver by any Party of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any Party to exercise, and no delay in exercising, any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power, or remedy by such Party preclude any other or further exercise thereof or the exercise of any other right, power, or remedy.

2.6. Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any law or public policy, all other terms or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, such provision shall be modified so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the Transactions are consummated as originally contemplated to the greatest extent possible.

2.7. Entire Agreement. This Agreement and the PSTEA represent the entire understanding and agreement between the Parties with respect to the subject matter hereof and supersede all prior and contemporaneous agreements or understandings, whether written or oral, among the parties with respect to the subject matter hereof

2.8. Further Assurances. The parties agree to execute such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement.

2.9. Third Parties. Nothing in this Agreement, express or implied, is intended to confer upon any person, other than the parties hereto and their successors and assigns, any rights or remedies under or by reason of this Agreement.

2.10. Counterparts. This Agreement may be executed in counterparts (whether in electronic, or photostatic format or otherwise), each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement.
