        Subject to the Right of First Refusal and
        Option below, Aegis shall not license to any third party, and hereby grants an exclusive option to Lightlake to license, the Aegis

|            | Beginning on the first anniversary of the
effective date of the license agreement and through the first Product approval by Lightlake, Lightlake shall be required to make
minimum quarterly nonrefundable payments (“Quarterly Payments”) to Aegis in the amount of $25,000. These Quarterly
Payments would be fully creditable and treated as a prepayment against future milestones or royalties and are required in order
to maintain the license.



If, at the time when any milestone payment listed above is due, Lightlake has not paid all other milestone
payments (if any) previously listed above, then at such time Lightlake shall pay all such unpaid milestone payments (other than
product approval milestones).

|Right
    of First Refusal and Option | Provided that the license agreement has
        not been terminated, during the first two (2) year period beginning on the Effective Date, Aegis grants Lightlake a right of first
        refusal and option to add any, or all, of the compounds included under Option Compound or the Opioid Field to the license agreement
        (the “Lightlake Option”). Except as permitted by this section, Aegis shall not sell, license, offer for sale,
        offer for license or agree to sell or license any Aegis Technology relating to the Option Compound to any third party during the
        first two (2) year period beginning on the Effective Date.
        
        The following sets forth the procedure
        whereby Lightlake may exercise the Lightlake Option.
        
        1.In
the event that Aegis is approached by a third party interested in licensing the Option Compound(s) or the Opioid Field, Aegis
shall provide a written notice to Lightlake specifying the specific compound(s) or the Opioid Field (the “Aegis Notice”).
        
        2.Lightlake shall as soon as possible, but in no event longer than forty (40) days of receipt of the Aegis Notice, provide
        a written notice to Aegis whether Lightlake intends to exercise the Lightlake Option. In the event that Lightlake does not does
        exercise the Lightlake Option or fails to deliver to Aegis its intent to exercise such option within the forty (40) day period,
        then Aegis shall be free to grant such licenses to any other third party covering such Option Compound(s) or the Opioid Field for
        a period of up to twelve (12) months thereafter (the “Third Party Negotiation Period”).
        
        3.In the event Lightlake exercises the Lightlake Option, then as partial consideration for the grant to Lightlake of the rights
        under the license agreement for each Option Compound Lightlake shall pay to Aegis a nonrefundable and noncreditable license issuance
        fee of Two-Hundred and Fifty Thousand U.S. dollars (U.S. $250,000). Lightlake may elect to pay up to 50% of the Option Fee by issuing
        to Aegis shares of Lightlake’s common stock subject to the procedures for the License Fee payment in the form of Lightlake
        shares. In the event that Lightlake exercises the Lightlake Option specific to the Opioid Field then Lightlake shall pay to Aegis
        the Option Fee.
        
        4.In the event Lightlake does not exercise the Lightlake Option and the other interested third party either: (i) does not
        license within the Third Party Negotiation Period, under either feasibility or commercial licenses, the Option Compound; or (ii)
        the license pertaining to such Option Compound that has been exclusively licensed has been subsequently terminated, or prior to
        the end of the Third Party Negotiation Period negotiations with the interested third party licensee are terminated as determined
        in Aegis’ sole discretion, then Aegis shall within thirty (30) days of such termination provide written notice to Lightlake
        that the Option Compound remains available. Any subsequent inquiry by the same or any other third party interested in licensing
        such Option Compound shall again be subject to the requirements of this section.
        
        5.Without
limiting the foregoing right of first refusal, Lightlake may in its sole discretion elect to affirmatively exercise the Lightlake
Option with respect to any available Option Compound at any time by written notice to Aegis, in which case the same license issuance
fees specified in subsection 3 shall apply.

|Maximum Reductions:       | Notwithstanding anything other to the contrary, the provisions which allow for a reduction, credit or offset from the regularly scheduled payment rate or amount (e.g., royalties and milestone payments) shall not be used cumulatively to result in more than a fifty percent (50%) reduction in the regularly scheduled payment; but any unused reduction, credit or offset, as a result of this fifty percent (50%) floor, may be carried forward and used subsequently in the future as a reduction, credit or offset against a later accruing payment obligation, but still subject to the same fifty percent (50%) floor as set forth above.
