No Indemnified Party shall have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company for or in connection with the transactions contemplated hereby, except to the extent such liability is found in a final, non-appealable order of a court of competent jurisdiction to have resulted from such Indemnified Party’s bad faith, actual fraud, gross negligence or willful misconduct. In no event, however, shall the Company or any Indemnified Party be liable on any theory of liability for any special, indirect, consequential or punitive damages. Without the prior written consent of the Indemnified Parties, the Company agrees that it will not enter into any settlement of any lawsuit, claim or other proceeding arising out of this Agreement, the Definitive Documentation, or the transactions contemplated hereby or thereby, solely to the extent such Definitive Documentation or transactions contemplated thereby relate to this Agreement and the Convertible Preferred Equity Offering, unless such settlement (i) includes an explicit and unconditional release from the party bringing such lawsuit, claim or other proceeding of all Indemnified Parties and (ii) does not include a statement as to or an admission of fault, culpability, or a failure to act by or on behalf of any Indemnified Party. No Indemnified Party shall be liable for any damages arising from the use by unauthorized persons of any information made available to the Indemnified Parties by the Company or any of its representatives through electronic, telecommunications or other information transmission systems that is intercepted by such persons. No Indemnified Party shall settle any lawsuit, claim, or other proceeding arising out of this Agreement, the Definitive Documentation, or the transactions contemplated hereby or thereby without the prior written consent of the Company (such consent not to be unreasonably withheld or delayed). Notwithstanding the foregoing, an Indemnified Party shall be entitled to no indemnification by the Company for any claim, damage, loss, liability, or expense incurred by or asserted or awarded against such Indemnified Party for any violation of Law by such Indemnified Party.

10.4 Survival. The representations and warranties made in this Agreement will not survive the Closing and shall expire and be of no further force and effect simultaneously therewith.

10.5 No Waiver of Rights. All waivers hereunder must be made in writing, and the failure of any Party at any time to require another Party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation.

10.7 Headings. The section and subsection headings in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

10.8 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 and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated hereby 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, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

10.9 Entire Agreement. This Agreement and the agreements and documents referenced herein constitute the entire agreement of the Parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, between the Parties with respect to the subject matter hereof.

10.10 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Except as set forth

below, neither this Agreement nor any of the rights, interests or obligations under this Agreement will be assigned by either Party (whether by operation of law or otherwise) without the prior written consent of the other Party. Notwithstanding the foregoing, the rights, obligations and interests hereunder may be assigned, delegated or transferred, in whole or in part, by the Backstopper to Affiliates and/or one or more third-parties satisfactory to the Company; provided, however, that such transferee, as a condition precedent to such transfer, becomes a Party to this Agreement and assumes the obligations of the Backstopper under this Agreement by executing an addendum substantially in the form set forth in Exhibit A (the ”Addendum”) and an assumption in substantially the form set forth in Exhibit B hereto (the “Assumption Agreement”) and deliver the same to the Company in accordance with Section 10.6, and provided, further, that (a), with respect to a transfer to an Affiliate of a Backstopper, the Backstopper either (i) shall have provided an adequate equity support letter or a guarantee of such Affiliate-transferee’s Commitment, in form and substance reasonably acceptable to the Company or (ii) shall remain fully obligated to fund such Commitment and (b), with respect to a transfer to a third party, the Company, acting in good faith, shall have consented in writing to such transfer (which consent shall not be unreasonably withheld, conditioned or delayed) and shall have determined, in its reasonable discretion, after due inquiry and investigation, that such transferee is reasonably capable of fulfilling such obligations, or, absent such a determination, the proposed transferee shall have deposited with an agent of the Company or into an escrow account under arrangements satisfactory to the Company funds sufficient, in the reasonable determination of the Company, to satisfy such proposed transferee’s Commitment. Any transfer that is made in violation of the immediately preceding sentence shall be null and void ab initio, and the Company shall have the right to enforce the voiding of such transfer.

10.11 No Third-Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the Parties and their respective successors and permitted assigns and, except as expressly set forth in Section 9, nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever.

10.12 Amendment. This Agreement may not be altered, amended, or modified except by a written instrument executed by or on behalf of the Company and the Backstopper.

10.13 Governing Law. This Agreement shall be interpreted, construed and enforced in accordance with the laws of the State of New York, without regard to the conflicts of law principles thereof.

10.14 Consent to Jurisdiction. Each of the Parties (a) irrevocably and unconditionally agrees that any actions, suits or proceedings, at Law or equity, arising out of or relating to this Agreement or any agreements or transactions contemplated hereby shall be heard and determined within the State of Texas; (b) irrevocably submits to the jurisdiction of such court in any such action, suit or proceeding; (c) consents that any such action, suit or proceeding may be brought in such courts and waives any objection that such Party may now or hereafter have to the venue or jurisdiction or that such action or proceeding was brought in an inconvenient court; and (d) agrees that service of process in any such action, suit or proceeding may be effected by providing a copy thereof by any of the methods of delivery permitted by

Section 10.6 to such Party at its address as provided in Section 10.6 (provided that nothing herein shall affect the right to effect service of process in any other manner permitted by Law).

10.15 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT, OR ANY OTHER THEORY). EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.15.

10.16 Currency. Unless otherwise specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean United States (U.S.) dollars and all payments hereunder shall be made in United States dollars.

10.17 Counterparts. This Agreement may be executed and delivered (including by facsimile or electronic transmission) in one or more counterparts, and by the different Parties 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.

10.18 Specific Performance. Each Party acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions contemplated by this Agreement, the other Party would not have an adequate remedy at law for money damages in the event that this Agreement has not been performed in accordance with its terms, and therefore agrees that the other Party shall be entitled to specific performance and injunctive or other equitable relief as the sole and exclusive remedy of any such breach, without the necessity of proving the inadequacy of monetary damages as a remedy.

10.19 Rules of Construction. The Parties and their respective legal counsel participated in the preparation of this Agreement, and therefore, this Agreement shall be construed neither against nor in favor of any of the Parties, but rather in accordance with the fair meaning thereof. Unless the context of this Agreement clearly requires otherwise, references to the plural include the singular, references to the singular include the plural, the term “including” is not limiting, and the term “or” has, except where otherwise indicated, the inclusive meaning represented by the phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder” and similar terms in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. Section, subsection, clause, schedule, annex and exhibit references are to this Agreement unless otherwise specified. Any reference to this Agreement shall include all alterations, amendments, changes, extensions, modifications, renewals, replacements,

substitutions, and supplements thereto and thereof, as applicable. Whenever the context may require, any pronoun includes the corresponding masculine, feminine and neuter forms.
