This Warrant is being issued as of October 10, 2019 (the “Warrant Issue Date”).

1. Term of Warrant. Subject to the terms and conditions set forth herein, this Warrant shall be exercisable, in whole or in part, during the term commencing on the Warrant Issue Date and ending at 5:00 p.m., Central Time, on the tenth anniversary of the Warrant Issue Date, and shall be void thereafter (the “Term”).

2. Exercise of Warrant.

(a) Method of Exercise. During the Term, The purchase rights represented by this Warrant are exercisable by the Holder, in whole or in part, at any time or from time to time by the surrender of this Warrant and the Notice of Exercise attached hereto as Exhibit A duly completed and executed on behalf of the Holder, at the principal office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company), upon either payment in cash, certified check or wire transfer of funds of the Exercise Price or by an exchange of shares of Common Stock as described in the following paragraph.

In lieu of a cash payment, the Holder may elect to exchange all or some of this Warrant for shares of Common Stock equal to the value of the amount of the Warrant being exchanged on the date of exchange. If the Holder elects to exchange this Warrant for shares, the Holder shall tender to the Company the Warrant for the amount being exchanged, along with written notice of the Holder’s election to exchange some or all of this Warrant, and the Company shall issue to the Holder the number of shares of Common Stock computed using the following formula:

X= Y(A-B)

A

This Warrant shall be exercisable immediately in whole or in part.

(b) Issuance of Shares. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date. As promptly as practicable on or after such date and in any event within three (3) days thereafter, the Company at its expense shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the Warrant Shares issuable upon such exercise. In the event that this Warrant is exercised in part, the Company, at the request of the Holder and at Company expense, will execute and deliver a new Warrant of like tenor exercisable for the number of Warrant Shares for which this Warrant may then be exercised.

(c) Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(c), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the transfer agent for the Common Stock setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within one trading day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

3. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled (after aggregating all shares that are being issued upon such exercise), the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.

4. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

5. No Rights as Stockholder. This Warrant does not entitle the Holder to any voting rights or other rights as a stockholder of the Company prior to the exercise hereof.

6. Restrictions on Transferability of Securities.

(a) Restrictions on Transferability. This Warrant and the Warrant Shares issuable upon exercise of this Warrant (collectively the “Securities”) shall not be sold, assigned, transferred or pledged except upon the conditions specified in this Section 6.

(b) Restrictive Legends. Each certificate representing the Securities and any other securities issued in respect of the Securities upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted by the provisions of Section 6(c)) be stamped or imprinted with a legend in substantially the following form (in addition to any legend required under applicable state securities laws):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS. SUCH SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND MAY NOT BE OFFERED FOR SALE, SOLD, DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FILED BY THE ISSUER WITH THE U.S. SECURITIES AND EXCHANGE COMMISSION COVERING SUCH SECURITIES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH REGISTRATION IS NOT REQUIRED.

Each holder of Securities and each subsequent transferee consents to the Company making a notation on its records and giving instructions to any transfer agent of the Securities in order to implement the restrictions on transfer established in this Section 6.

(c) Notice of Proposed Transfers. The Securities may be sold or transferred (i) as permitted pursuant to Section 6(d) hereof, and (ii) otherwise, with the prior written consent of the Company, such consent not to be unreasonably withheld or delayed. Each holder of a warrant or stock certificate, as the case may be, representing the Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Warrant. Such holder agrees not to make any disposition of all or any portion of the Securities unless and until (X) there is then in effect a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), covering such proposed disposition and such disposition is made in accordance with such registration statement or (Y) such holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, such holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act.

(d) Exempt Transfers. Notwithstanding the foregoing Section 6(c), no such registration statement or opinion of counsel shall be necessary for a transfer by a holder of a warrant or stock certificate, as the case may be, representing Securities in compliance with Rule 144(k) (or any successor provision) of the Securities Act so long as the Company is furnished with satisfactory evidence of compliance with such rule.

7. Reservation of Stock. The Company covenants that during the term this Warrant is exercisable, the Company will reserve from its authorized and unissued capital stock a sufficient number of shares to provide for the issuance of Warrant Shares upon the exercise of this Warrant and, from time to time, will take all steps necessary to amend its Certificate of Incorporation to provide sufficient reserves of shares of capital stock issuable upon exercise of this Warrant. The Company further covenants that all Warrant Shares that may be issued upon the exercise of rights represented by this Warrant and payment of the Exercise Price, all as set forth herein will be duly and validly authorized and issued, fully paid and non-assessable and free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously therewith). The Company agrees 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 Warrant Shares upon the exercise of this Warrant.

8. Adjustments. If the Company at any time while this Warrant remains outstanding and unexpired shall (i) split, subdivide, combine or recapitalize the issued and outstanding Common Stock into a different number of shares of the same class, (ii) increase the number of shares of Common Stock outstanding without receiving compensation therefore in money, services or property, or (iii) by reclassification or recapitalization of securities or otherwise, change the Common Stock into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the Warrant Shares immediately prior to the happening of such event.

In addition, in the event of a Corporate Event (defined below), the Holder shall be entitled to receive, in lieu of the Warrant Shares, such shares of capital stock or other securities or property as may be issuable or payable with respect to or in exchange for the number of Warrant Shares which the Holder would have received had he exercised the Warrant immediately prior to such Corporate Event. A “Corporate Event” means any of the following: (i) a dissolution or liquidation of the Company, (ii) a sale of all or substantially all of the Company’s assets or (iii) a merger, consolidation or combination involving the Company (other than a merger, consolidation or combination (A) in which the Company is the continuing or surviving corporation and (B) which does not result in the outstanding shares of Common Stock being converted into or exchanged for different securities, cash or other property, or any combination thereof).

9. Registration Rights. For so long as any Warrant Shares remain outstanding and remain subject to resale restrictions, if the Company files any registration statement for the issuance, sale and/or resale of any shares of its Common Stock, then the Company shall be obligated to include in such registration statement the resale of all Warrant Shares; subject to the following conditions and restrictions: (i) if such rights are exercised by the Holder in connection with an underwritten offering of shares of capital stock of the Company, then the Company shall not be required to include any Warrant Shares in such underwritten offering unless the Holder accepts the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of Company’s capital stock offering; (ii) for the avoidance of doubt, in no event shall the Company be required to file a post-effective amendment to any registration statement currently in effect as of the Warrant Issue Date in order to accommodate the Holder’s rights granted pursuant to this Section 9; and (iii) the rights of the Holder described in this Section 9 shall not apply with respect to any Warrant Shares which the Holder may sell pursuant to Rule 144(k) or which Consultant otherwise may sell in compliance with the Securities Act of 1933, as amended, and applicable state securities laws without volume, manner of sale or other limitations or restrictions.

10. Amendments and Waivers. This Warrant may not be amended except with the written consent of the Company and the Holder. Any amendment effected in accordance with this Section 10 shall be binding upon each future holder of this Warrant. No waivers of, or exceptions to, any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

11. 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 Holder 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 Holder shall be responsible for income taxes due under federal, state or other law, if any such tax is due.

12. Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery or overnight courier, then such notice shall be deemed given upon receipt of confirmation of such delivery, and (ii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) five days after such notice is deposited in first class mail, postage prepaid. All notices shall be addressed as follows: if to the Holder, c/o Fredrick G. Lautz Esq. Quarles & Brady, 411 East Wisconsin Avenue Suite 2040, Milwaukee, Wisconsin 53202, and if to the Company, at One Riverway, Suite 1700, Houston, Texas 77056 or at such other address as the Holder or the Company may designate by ten days’ advance written notice to the other.

13. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Holder) 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 Holder.

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

15. Saturdays, Sundays and Holidays. If the last or appointed day for the taking of any action or the expiration of any right granted herein shall be a Saturday, Sunday or legal holiday, then (notwithstanding anything herein to the contrary) such action may be taken or such right may be exercised on the next succeeding day that is not a Saturday, Sunday or legal holiday.

16. Counterparts. This Warrant may be executed through the use of separate signature pages or in any number of counterparts (including by facsimile or Portable Document Format (pdf) transmission), and each of such counterparts shall, for all purposes, constitute one agreement binding on all the parties, notwithstanding that all parties are not signatories to the same counterpart.
