    EXHIBIT A

    In the event that Adapt proposes to enter into an agreement with a Commercial Sublicensee who would
        Exploit a Product in the European Union and/or the United Kingdom (as applicable, “Europe”), at Adapt’s request, the Parties will negotiate in good faith to
        amend the License Agreement as necessary to implement the terms described below.

    	
            Term

          	
            Addition or Modification

          
	
            Revenue sharing

          	
            Opiant (or its designee) would share in royalties, milestone payments and payments for any supplied Product, less
                all costs incurred in generating such European revenues (including, amongst others, development, regulatory, licensing, safety, supply and distribution costs attributable to Europe) received by Adapt from a Sublicensee in Europe (“Europe
                Net Revenues”) based on the following:

            • [**]% of all such amounts, up to $[**] of cumulative revenue; and

            • [**]% of all such amounts in excess of $[**] in cumulative revenue.

            In the event that Opiant (or its designee) does not receive the $[**] milestone contemplated by Section 5.2.4 of
                the License Agreement, then the $[**] threshold contemplated above shall be reduced to $[**].

            Amounts comprising Europe Net Revenues and revenues earned by any Sublicensee in Europe would be excluded for
                purposes of determining Net Sales on which Opiant (or its designee) would otherwise be entitled to royalties under the License Agreement, subject to the provisions set forth below in Global Sales Milestones and Royalty Tiers.  Adapt shall
                make the revenue share payments in respect of the Europe Net Revenues to Opiant (or its designee) on a Calendar Quarter basis in accordance with the terms of Section 5.6 of the License Agreement and any other written instructions agreed to
                by Adapt.

          
	
            Global Sales Milestones and Royalty Tiers

          	
            Europe Net Revenues received by Adapt from any Sublicensee in Europe would be included for purposes of determining
                Net Sales giving rise to sales-based milestones pursuant to Section 5.3.1 of the License Agreement and for purposes of determining royalty tiers set forth in Section 5.4.1 of the License Agreement.  Sublicensee revenues in Europe would be
                excluded for purposes of such determinations.

            The $75 million Annual Net Sales Milestone Threshold specified in Section 5.3.1 of the License Agreement would be
                changed to $74 million.

            The $200 million Annual Net Sales Milestone Threshold specified in Section 5.3.1 of the License Agreement would be
                changed to $ 185 million.
