CLS Holdings USA, Inc., a Nevada corporation  (the “Company”), for value received and, except as modified hereby, pursuant to the terms of a certain Membership Interest Purchase Agreement to which this Note shall be attached as Exhibit A, hereby promises unconditionally to pay to the order of Serenity Wellness Enterprises, LLC, a Nevada limited liability company (the “Holder”), as nominee solely for the benefit of the sellers of the membership interests in Alternative Solutions, LLC, a Nevada limited liability company (“AS”) or one of its subsidiaries, who are named on Schedule 1 hereto together with the amount due hereunder to each of them (collectively, the “Selling Members”), by paying to the Selling Members directly at the address set forth for each of them on Schedule 1 hereof, in lawful money of the United States of America (“Dollars” or “$”) and in immediately available funds, the aggregate principal amount of FOUR MILLION DOLLARS ($4,000,000), (the “Principal”), or such lesser amount as shall be outstanding at such time, it being acknowledged that the initial portion of the Principal due to each Selling Member is as set forth on Schedule 1, plus all accrued and unpaid interest thereon (the “Interest”) on the Maturity Date (as defined below).

the AS subsidiaries from AS.  As a result, the “Sellers,” as defined in the MPA, now refers to the Selling Members.  The Holder shall have the sole right to act on behalf of the Selling Members under this Note but the Company shall direct payment of amounts due to the Sellers directly to the Selling Members, in accordance with their interests set forth on Schedule 1, unless directed to do otherwise by the Holder.
