    WHEREAS, ABI and
        Optionee desire to enter into this Agreement to evidence a grant under the Plan and to set forth their mutual understanding with regard to Optionee’s participation in the Plan, and the terms of the Options granted thereunder to Optionee;

    

    

    THEREFORE, in
        consideration of the mutual covenants and agreements herein expressed, and for other good and adequate consideration the receipt and sufficiency of which are evidenced by the execution hereof, ABI and Optionee hereby agree as follows:

    

    

    I.

    

    

    DEFINITIONS

    

    

    “Plan” shall mean
        that certain Amarillo Biosciences, Inc., 2018 Officers, Directors, Employees and Consultants Nonqualified Stock Option Plan adopted by the Board of Directors of ABI on September 26, 2018.

    

    

    II.

    

    

    THE AWARD

    

    

    This Agreement shall evidence the grant and award to Optionee under the Plan of Options to purchase 376,000 shares of the
        voting Common Stock of ABI.  The grant was made to be and become effective as of September 26, 2018.  The Option Price is $.38 per share and was the closing price of the Common Stock on September 25, 2018.

    
      1

      
        


    

    

    

    The Options are exercisable during a period of five (5) years from the date of grant and vest 20% annually, commencing one (1) year from date
        of grant.  The Options are exercisable in whole or in part or from time to time during the aforesaid term, provided, however, that in no event shall any such Option be exercisable at any time after the termination of Optionee’s association with the
        Company, except as provided in Sections 2.05, 2.06, and 2.07 of the Plan.

    

    

    III.

    

    

    TERMS AND CONDITIONS

    

    

    The Options and Limited Rights (if Limited Rights have been granted under Article II, above) are granted and received
        subject to all of the terms and conditions of the Plan, as well as any further terms and conditions set forth in the Resolution(s) granting the Options to Optionee.  A copy of the Plan and the adopting Resolution(s) are attached to this Agreement,
        are hereby incorporated by reference in their entirety, and are made a part hereof as if fully set forth herein.  In the event of any conflict between this Agreement, the Plan, and/or the granting Resolution(s), the terms of the Plan and the
        granting Resolution(s) shall control.

    

    

    IV.

    

    

    SHARES NOT REGISTERED

    

    

    Upon exercise of any of the Options by Optionee, shares of the Company shall be issued to Optionee subject to any
        applicable restrictions under federal or state securities laws, and regulations promulgated thereunder, and Optionee agrees to accept such shares subject to such restric-tions, and bearing any required or appropriate legends.  Rule 144 promulgated
        under the U.S. Securities Act of 1933 is currently available for qualifying resales of restricted shares; however, there is no assurance that the Common Stock will continue to qualify for resale pursuant to Rule 144, and Optionee is responsible for
        determining the availability of Rule 144, before relying thereon.

    

    

    V.

    

    

    TAX CONSIDERATIONS

    

    

    The Company does not and will not render tax advice to Optionee.  Optionee represents that he will consult his own tax
        advisor with respect to the tax aspects of both the exercise of an Option and the disposition of shares acquired pursuant to exercise of an Option.  The Options are not qualified stock options within the meaning of the Internal Revenue Code of 1986, and therefore the exercise of the Options may be expected to be a taxable event.

    VI.

    

    

    NO RIGHT TO CONTINUED EMPLOYMENT

    

    

    Optionee's participation in the Plan does not confer upon Optionee the right to continue in the employment of ABI, nor
        does it affect any right which ABI may have to terminate the employment of Optionee.  Neither the Option grant nor this Agreement are intended to vary the terms of any contract of employment between ABI and Optionee.  If Optionee does not presently
        have an employment contract with the Company, this Agreement shall not be construed as a contract of employment.  In the event of termination of Optionee’s employment with the Company for any reason, Optionee shall retain only those Options which
        shall have vested prior to such termination, and shall be entitled to exercise the vested Options after such termination during the time period set forth in the Plan.

    

    

    VII.

    

    

    NO RIGHTS AS A SHAREHOLDER

    

    

    Optionee shall have no rights as a shareholder with respect to Option shares unless and until certificates evidencing such
        shares shall have been issued to Optionee.

    

    

    VIII.

    

    

    TAX WITHHOLDING

    

    

    Upon the exercise of any of the Options, ABI shall have the right to require Optionee to pay to ABI the amount of any
        taxes that are required by law to be withheld with respect to such exercise.

    

    

    IX.

    

    

    ASSIGNABILITY

    

    

    Although limited transferability is allowed under Article VI of the Plan, Optionee acknowledges that he is responsible for
        consulting with competent tax and securities counsel before transferring Options, and that it may be necessary to make appropriate disclosures to his transferee, regarding lack of marketability.  In addition, transfers of Options for value may
        cause Optionee to recognize taxable income.
