(b) All Warrants shall be held and owned under the express condition that the provisions of this Section are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Warrant Certificates and shall preclude (to the extent lawful) all other rights and remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with

Shares, the Exercise Price, as then in effect, shall be proportionately increased, and the Company shall proportionately reduce the number of Shares then subject to exercise under this Warrant (and not previously exercised). 

12. Reorganization, Reclassifications, Consolidation or Merger. If, prior to the Expiration Time, there shall be a reorganization or

Agreement and upon payment of the Exercise Price, the number of shares of stock or other securities or property of the Company or of the successor entity (or its parent company) resulting from such consolidation or merger, as the case may be, to
which a holder of Shares, deliverable upon the exercise of a Warrant, would have been entitled upon such reorganization, reclassification, consolidation or merger; and, in any case, the Company shall make appropriate adjustments (as determined by
the board of directors of the Company in its sole discretion) in the application of the provisions with respect to the rights and interests of the Holders so that the provisions set forth in this Agreement (including the adjustment to the Exercise

decreased number of shares purchasable upon the exercise of the Warrant(s) and shall set forth in reasonable detail the method of calculation for each. Notwithstanding anything to the contrary set forth herein or in the Warrant Certificates, the
Company may, at its option, issue new Warrant Certificates evidencing the Warrants, in such form as may be approved by the Company, to reflect any adjustment or change in the Exercise Price and the number or kind of stock or other securities or
property purchasable upon exercise of the Warrants. 
 14. Miscellaneous. 

(a) Any notice or other communication required or permitted to be made hereunder shall be in writing, duly signed by the party giving such
notice or communication and shall be deemed delivered and effective when given personally or mailed by first-class registered or certified mail, postage prepaid as follows (or at such other address for a party as shall be specified by like notice):

available out of its authorized and unissued Shares or out of any Shares held in treasury that number of Shares that will from time to time be sufficient to permit the exercise in full of all outstanding Warrants. The Company shall take all such
action as may be necessary to ensure that all Shares delivered upon exercise of any Warrants shall, at 

  
 4 













 the time of delivery of the Warrant Certificates for such Shares, be duly authorized,
validly issued, fully paid and nonassessable. 
 (c) The Company shall pay when due and payable any and all federal and state transfer taxes
and charges (other than any applicable income taxes) that may be payable in respect of the issuance and delivery of Warrant Certificates or of certificates for Shares receivable upon the exercise of any Warrants; provided, however, that the Company
shall not be required to pay any tax that may be payable in respect of the issuance and delivery (i) of any Warrant Certificate or stock certificate registered in a name other than that of the Holder of the Warrant Certificate that has been
surrendered or (ii) of any Warrant Certificate under Section 7. 
 (d) No Holder, in his capacity as such, shall be entitled to
vote or receive dividends or shall be deemed for any other purpose the holder of the Shares or other securities which may at any time be issuable upon the exercise of such Warrant. Nothing contained herein or in any Warrant Certificate shall be
construed to confer upon any Holder, in his capacity as such, any of the rights of a shareholder of the Company, including any right to vote for the election of directors or upon any matter submitted to shareholders of the Company at any meeting
thereof, to give or withhold consent to any corporate action, or to receive notices of meeting or other actions affecting shareholders. 

(e) Each Holder, by accepting a Warrant Certificate, accepts and agrees to the terms of this Agreement. The terms of this Agreement shall be
binding upon the Company and the Holders and their respective heirs, successors, representatives and permitted assigns. Nothing expressed or referred to herein is intended or will be construed to give any person other than the Company or the Holders
any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provision herein contained, it being the intention of the Company and the Holders that this Agreement, the assumption of obligations and statements of
responsibilities hereunder, and all other conditions and provisions hereof are for the sole benefit of the Company and the Holders and for the benefit of no other person. 

(f) This Agreement constitutes the full understanding of the Company and the Holders, a complete allocation of risks between them and a
complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof and supersedes any and all prior agreements, whether written or oral, that may exist between the Company and any Holder with
respect thereto. Except as otherwise specifically provided in this Agreement, no conditions, usage of trade, course of dealing or performance, understanding or agreement purporting to modify, vary, explain or supplement the terms or conditions of
this Agreement will be binding unless hereafter or contemporaneously herewith made in writing and signed by the party to be bound, and no modification will be effected by the acknowledgment or acceptance of documents containing terms or conditions
at variance with or in addition to those set forth in this Agreement. 
 (g) The headings contained in this Agreement are for convenience of
reference only and will not affect in any way the meaning or interpretation of this Agreement. The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement will refer to this
Agreement as a whole and not to any particular provision in this Agreement. Each use herein of the masculine, neuter or feminine gender will be deemed to include the other genders. Each use herein of the plural will include the singular and vice
versa, in each case as the context requires or as is otherwise appropriate. The word “or” is used in the inclusive sense. References to a person are also to its permitted successors or assigns. No provision of this Agreement is to be
construed to require, directly or indirectly, any person to take any action, or omit to take any action, which action or omission would violate applicable law (whether statutory or common law), rule or regulation. 

  
 5 













 (h) This Agreement shall terminate upon the earlier of (i) the Expiration Time or
(ii) the close of business on the date on which all Warrants shall have been exercised. 
 (i) Notwithstanding anything in this
Agreement to the contrary, no Warrants will be exercisable and the Company will not be obligated to issue shares of common stock upon the exercise of Warrants unless at the time a Holder seeks to exercise such Warrants, a prospectus or registration
statement relating to the common stock issuable upon exercise of the Warrants is current with and the common stock has been registered or qualifies for or is deemed to be exempt under the securities laws of the United States and the state of
residence of the Holder of the Warrants. In the event that a prospectus or registration statement relating to the common stock issuable upon exercise of the Warrants is not current with and the common stock has not been registered or do not qualify
for or is not deemed to be exempt under the securities laws of the United States and the state of residence of the Holder of the Warrants, Holders will be unable to exercise Warrants and the Company will be under no obligation to settle any such
Warrant exercise. 
 THIS AGREEMENT, EACH WARRANT AND EACH WARRANT CERTIFICATE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF TEXAS WITHOUT REGARD TO THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS. IN THE EVENT OF A DISPUTE INVOLVING THIS AGREEMENT, THE PARTIES IRREVOCABLY AGREE THAT VENUE FOR SUCH DISPUTE
SHALL LIE EXCLUSIVELY IN A COURT OF COMPETENT JURISDICTION IN HARRIS COUNTY, TEXAS.
