(a) The Purchasers may unilaterally terminate any then remaining obligations of the Purchasers under this Section 1 (as well as any corresponding obligation of the Company) upon written notice to the Company if the Company (i) files, or has filed against it, a petition for voluntary or involuntary bankruptcy or pursuant to any other insolvency law, (ii) makes or seeks to make a general assignment for the benefit of its creditors, or (iii) applies for, or consents to, the appointment of a trustee, receiver or custodian for a substantial part of its property or business.

(b) Either Party may unilaterally terminate any then remaining obligations of the Purchasers under this Section 1 to purchase shares of Common Stock (as well as any corresponding obligations of the Company to issue such shares) upon written notice to the other Party if:

(i) the Company receives an aggregate of at least Twenty Million Dollars ($20,000,000) in gross proceeds from financing activities during the one (1) year period commencing on the Effective Date (excluding any amounts received by the Company pursuant to this Agreement or the Warrant);

(ii) any clinical trial substantially equivalent to the Phase I/II Study is initiated by a third party and such clinical trial is supported in whole or in part by the National Institutes of Health or its affiliated agencies or designees (e.g., Immune Tolerance Network); or

(iii) any person or group of persons (within the meaning of §13(d)(3) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) becomes the beneficial owner, directly or indirectly, of more than fifty percent (50%) of the outstanding shares of capital stock of the Company (including, for this purpose, all shares issuable upon the exercise of outstanding warrants, options or other rights for the purchase or acquisition from the Company of shares of capital stock of the Company) or the sale of all or substantially all of the assets of the Company.

(c) Any then remaining obligations of the Purchasers under this Section 1 to purchase shares of Common Stock (as well as any corresponding obligations of the Company to issue such shares) shall automatically terminate if the next potential obligation of the Purchasers under this Section 1 to purchase shares of Common Stock (e.g., the potential obligation to purchase Tranche 4 Shares if the Tranche 2 Closing and the Tranche 3 Closing have already taken place but the Tranche 4 Closing has not yet taken place) would entail an amount of shares of Common Stock which, when aggregated with all prior issuances of shares of Common Stock to the Purchasers under this Agreement plus all shares of Common Stock issued or issuable under the Warrant, based upon the applicable pricing formula (i.e., 90% of the 10-day volume weighted average price of the Common Stock for the ten (10) trading days immediately preceding the applicable milestone) would exceed 10,624,160 shares of Common Stock (as adjusted for any stock splits, dividends, combinations or other similar events occurring after the Effective Date).

(d) The Purchasers may unilaterally terminate any then remaining obligations of the Purchasers under this Section 1 (as well as any corresponding obligation of the Company) upon written notice to the Company if the Company fails to fulfill the Tranche 2 Milestone, Tranche 3 Milestone, Tranche 4 Milestone, or Tranche 5 Milestone by the dates provided for each such milestone; provided, however, that such right of termination shall be deemed waived with respect to any milestone if the Purchasers nonetheless participate in a closing hereunder which is triggered by such milestone.

(e) The Purchasers may unilaterally terminate any then remaining obligations of the Purchasers under this Section 1 (as well as any corresponding obligation of the Company) upon written notice to the Company if the Company is in material breach of this Agreement and such breach is not cured within thirty (30) days following written notice to the Company with respect thereto, with any obligation of the Purchasers otherwise due following any such notice being deemed suspended until the breach is cured by the Company or waived by the Purchasers or the cure period expires without the breach being cured by the Company or waived by the Purchasers.

(f) Any obligation of the Purchasers under this Section 1 to purchase shares of Common Stock (as well as any corresponding obligation of the Company to issue such shares) shall be suspended if and for so long as the Company does not have sufficient shares of Common Stock available in respect such obligation after taking into account the full amount of shares of Common Stock required to be reserved by the Company for issuance in the event of the exercise of all outstanding warrants, options or other rights for the purchase or acquisition from the Company of shares of Common Stock; provided, however, that (i) any such suspension shall not affect the determination of the applicable price for any tranche of Shares as otherwise provided in this Section 1, (ii) if any such suspension of an obligation of the Purchasers under this Section 1 to purchase shares of Common Stock shall occur, the Company shall provide notice to the Purchasers as soon as sufficient shares of Common Stock become available (including, for example, through an amendment of the Company’s Articles of Incorporation to increase the amount of authorized Common Stock) and any closing that has been delayed as the result of such suspension shall take place on the date specified in such notice (which shall be no sooner than five (5) business days following the date of such notice), and (iii) if any such suspension shall persist for more than one hundred twenty (120) days, any then remaining obligations of the Purchasers under this Section 1 to purchase shares of Common Stock (as well as any corresponding obligations of the Company to issue such shares) shall automatically terminate.

(d) prevent the issuance of any stop order or other suspension of effectiveness and, if such an order is issued, obtain the withdrawal of any such order at the earliest possible moment;

(e) prior to any public offering of Registrable Securities, (i) register or qualify or cooperate with the Purchasers in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions reasonably requested by the Purchasers, and (ii) do any and all other acts or things necessary or advisable to enable the distribution in such jurisdictions of the Registrable Securities covered by the Form S-3; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, or (y) subject itself to general taxation in any jurisdiction where it would not otherwise be so subject but for this subsection;

4.8 Indemnification.

(a) Indemnification by the Company. The Company will indemnify and hold harmless the Purchasers and each person, if any, who controls the Purchasers within the meaning of the 1933 Act against any losses, claims, damages or liabilities to which they may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in the Form S-3 or any Prospectus with respect thereto; (ii) the omission or alleged omission to state in the Form S-3 or any Prospectus with respect thereto a material fact required to be stated therein or necessary to make the statements therein not misleading; (iii) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with the Form S-3 or any Prospectus with respect thereto; or (iv) any failure to register or qualify the Registrable Securities in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on the Purchasers’ behalf. The Company will reimburse the Purchasers and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by the Purchasers or any controlling person of the Purchasers in writing specifically for use in the Form S-3 or any Prospectus with respect thereto.

(b) Indemnification by the Purchasers. The Purchasers agree to indemnify and hold harmless the Company, its directors, officers, employees and stockholders, and each person who controls the Company (within the meaning of the 0000 Xxx) against any losses, claims, damages, liabilities and expenses (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Form S-3 or any Prospectus with respect thereto to the extent that such untrue statement or omission is contained in or omitted from any information furnished in writing by the Purchasers or any controlling person of the Purchasers to the Company specifically for use in the Form S-3 or any Prospectus with respect thereto. In no event shall the liability of the Purchasers be greater in amount than the dollar amount of the proceeds received by the Purchasers upon the sale of the Registrable Securities included in the Form S-3.

(c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (x) the indemnifying party has agreed to pay such fees or expenses, (y) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (z) a material conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of the Purchasers be greater in amount than the dollar amount of the proceeds received by the Purchasers upon the sale of the Registrable Securities included in the Form S-3.

WARRANT TO PURCHASE SHARES
OF COMMON STOCK, PAR VALUE $0.01 PER SHARE

For VALUE RECEIVED, _________________ (“Warrantholder”) is entitled to purchase, subject to the provisions of this Warrant (this “Warrant”), from Opexa Therapeutics, Inc., a Texas corporation (“Company”), at any time after the date hereof (the “Initial Exercise Date”) and not later than 5:00 P.M., Central time, on the Expiration Date (as defined below), at an exercise price per share equal to (i) Fifty Cents ($0.50) if this Warrant is exercised on or before June 30, 2016, or (ii) One Dollar and Fifty Cents ($1.50) if this Warrant is exercised after June 30, 2016 (the applicable exercise price in effect being herein called the “Warrant Price”), Four Hundred Fifty-Four Thousand Five Hundred Forty-Five (454,545) shares (“Warrant Shares”) of the Company’s Common Stock, par value $0.01 per share (“Common Stock”). The number of Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as described herein. The “Expiration Date” shall mean April 9, 2018; provided, however, that upon a merger, consolidation, sale of substantially all assets or similar transaction involving the Company, at the option of the Company and upon at least ten (10) days prior written notice to Warrantholder, this Warrant must be exercised no later than immediately prior to the closing of any such transaction or it shall automatically expire upon such closing (in which event such closing shall be the Expiration Date). If not exercised on or before the Expiration Date, this Warrant shall become void.

1. Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder.

2. Transfers. This Warrant may be transferred only pursuant to a registration statement filed under the Securities Act of 1933, as amended (the “Securities Act”), or an exemption from such registration. Subject to such restrictions, the Company shall transfer this Warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender hereof for transfer, properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act, to establish that such transfer is being made in accordance with the terms hereof, and a new Warrant shall be issued to the transferee (who shall thereafter be the Warrantholder hereunder) and the surrendered Warrant shall be canceled by the Company.

3. Exercise of Warrant. The Warrantholder may exercise this Warrant, in whole or in part, at any time after the Initial Exercise Date and prior to 5:00 p.m. Central Time on the Expiration Date upon (i) written notice, in the form attached hereto as APPENDIX A (the “Exercise Notice”), of the Warrantholder’s election to exercise this Warrant, and (ii) payment by cash, certified check or wire transfer of funds for the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued to the Warrantholder or the Warrantholder’s designee, as the record owner of such shares, as of the close of business on the date on which the Warrant Price shall have been paid and the completed Exercise Notice shall have been delivered. The Warrantholder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Certificates for the Warrant Shares so purchased shall be delivered to the Warrantholder within a reasonable time, not exceeding three (3) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Warrantholder and shall be registered in the name of the Warrantholder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the Warrantholder a new Warrant representing the right to purchase the number of shares with respect to which this Warrant shall not then have been exercised. As used herein, “business day” means a day, other than a Saturday or Sunday, on which banks in Houston, Texas are open for the general transaction of business. The Warrantholder’s acceptance of this Warrant as well as each exercise hereof shall each constitute the affirmation by the Warrantholder that the representations and warranties contained in APPENDIX B attached hereto are true and correct in all material respects with respect to the Warrantholder as of the time of such acceptance and as of the time of each exercise. The Warrantholder shall promptly physically surrender this Warrant to the Company in the event the Warrant is exercised. The Warrantholder and the Company shall maintain records showing the amount exercised and the dates of such exercise. The Warrantholder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provision of this paragraph, following exercise of a portion of the Warrant, the number of Warrant Shares of this Warrant may be less than the amount stated on the face hereof.

4. Compliance with Securities Laws. This Warrant may only be exercised by the Warrantholder in accordance with applicable securities laws. The Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant, and a similar legend on any security issued or issuable upon exercise of this Warrant, unless counsel for the Company is of the opinion as to any such security that such legend is unnecessary.

5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued, and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company the amount of such tax or has established to the Company’s reasonable satisfaction that such tax has been paid. The Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due.

6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon surrender and cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with respect thereto, if requested by the Company.

7. Reservation of Common Stock. The Company represents and warrants that on the date hereof, it has duly authorized and reserved, and covenants that at any time when this Warrant is exercisable, the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 7, out of the authorized and unissued shares of Common Stock, at least a number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding. The Company covenants that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company.

8. Adjustments.

(a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares, then (i) the Warrant Price in effect immediately prior to the date on which such change shall become effective shall be adjusted by multiplying such Warrant Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such change and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the number of Warrant Shares purchasable upon exercise of this Warrant shall be adjusted by multiplying the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior to the date on which such change shall become effective by a fraction, the numerator of which is shall be the Warrant Price in effect immediately prior to the date on which such change shall become effective and the denominator of which shall be the Warrant Price in effect immediately after giving effect to such change, calculated in accordance with clause (i) above. Such adjustments shall be made successively whenever any event listed above shall occur.

(b) Unless the Expiration Date occurs coincident therewith (as provided in the first paragraph of this Warrant): (i) if any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof; and (ii) the Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Warrantholder, at the last address of the Warrantholder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Warrantholder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions.

(c) In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 8(a)), or subscription rights or warrants, the Warrant Price to be in effect after such payment date shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Market Price (as defined below) per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company’s Board of Directors (the “Board of Directors”) in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price per share of Common Stock immediately prior to such payment date. “Market Price” of a share of Common Stock on any date shall mean, (i) if the shares of Common Stock are listed on the NASDAQ Stock Market, the official closing price reported on that date; (ii) if the shares of Common Stock are no longer listed on the NASDAQ Stock Market and are listed on any other national securities exchange, the last sale price of the Common Stock reported by such exchange on that date; (iii) if the shares of Common Stock are not listed on any such exchange and the shares of Common Stock are traded in the over-the-counter market, the last price reported on such day by the OTC Bulletin Board; (iv) if the shares of Common Stock are not listed on any such exchange or quoted on the OTC Bulletin Board, then the last price quoted on such day in the over-the-counter market as reported by the National Quotation Bureau Incorporated (or any similar organization or agency succeeding its functions of reporting prices); or (v) if none of clauses (i)-(iv) are applicable, then as determined in good faith by the Board of Directors.

(d) An adjustment to the Warrant Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment.

(e) In the event that, as a result of an adjustment made pursuant to this Section 8, the Warrantholder shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in this Warrant.

9. Fractional Interest. The Company shall not be required to issue fractions of Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such fractional share, shall pay to the exercising Warrantholder an amount in cash equal to the fair market value of such fractional share of Common Stock on the date of exercise.

10. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder.

11. Notices to Warrantholder.

(a) Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment.

(b) The Company hereby covenants to the Warrantholder that, from the date hereof and for so long as this Warrant remains not fully exercised, it shall give written notice promptly to the Warrantholder upon the happening of any of the following events: (i) the admission in writing by the Company of its insolvency; (ii) the commission of any voluntary act of bankruptcy by the Company; (iii) the execution by the Company of a general assignment for the benefit of creditors; (iv) the filing by or against the Company of any petition in bankruptcy or any petition for relief under the provisions of the federal bankruptcy act or any other state or federal law for the relief of debtors and the continuation of such petition without dismissal for a period of sixty (60) days or more; (v) the appointment of a receiver or trustee to take possession of the property or assets of the Company; (vi) any dissolution of the Company; (vii) the adoption by the Company of any plan of liquidation; or (viii) the commencement against the Company of any case, proceeding or other action seeking issuance of a warrant of attachment, execution, distraint or similar process against all or any substantial part of its assets which results in the entry of an order for any such relief which shall not have been vacated, discharged, or stayed or bonded pending appeal within sixty (60) days from the entry thereof.

12. Identity of Transfer Agent. The Transfer Agent for the Common Stock is Continental Stock Transfer & Trust, 00 Xxxxxxx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000. Upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will mail to the Warrantholder a statement setting forth the name and address of such transfer agent.

13. Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given and received as hereinafter described (i) if given by personal delivery, then such notice shall be deemed received upon such delivery, (ii) if given by facsimile, then such notice shall be deemed received upon receipt of confirmation of complete transmittal, (iii) if given by certified mail return receipt requested, then such notice shall be deemed received upon the day such return receipt is signed, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one business day after delivery to such carrier. Copies of such notices shall also be transmitted by email.

14. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and inure to the benefit of its respective successors and permitted assigns hereunder.

15. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Warrant shall be governed by, and construed in accordance with, the internal laws of the State of Texas, without reference to the choice of law provisions thereof. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably submits to the exclusive jurisdiction of the courts of the State of Texas located in Xxxxxx County and the United States District Court for the Southern District of Texas for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Warrant and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Warrant. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS WARRANT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

16. No Rights as Shareholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any rights as a shareholder of the Company by virtue of its ownership of this Warrant.

17. Amendment; Waiver. Any term or provision of this Warrant may be amended or waived upon the written consent of the Company and the Warrantholder.

18. Remedies; Other Obligations; Breaches and Injunctive Relief. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Warrantholder right to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Warrantholder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Warrantholder shall be entitled, in addition to all other available remedies, an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

19. Authorized Shares. The Company covenants that during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the trading market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Warrantholder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Warrantholder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

20. Section Headings. The section headings in this Warrant are for the convenience of the Company and the Warrantholder and in no way alter, modify, amend, limit or restrict the provisions hereof.
