1.
Due on Demand. Notwithstanding
any terms in this Note to the contrary, the enumeration in this Note of specific obligations of Borrower to Lender and/or conditions

3.
Interest.
Interest under this Note shall be as follows:

 

3.1
Interest Rate. Borrower shall pay interest to
Lender on the unpaid principal amount of the Loan outstanding hereunder, accruing from the date hereof to the date on which the entire
principal sum hereof has been paid in full, computed on the basis of the actual number of days elapsed in a 365 day year, at a rate per
annum which shall be equal to 8%, compounded monthly as of the last day of each calendar month. In no event shall interest exceed the
maximum legal rate permitted by law.

 

3.2
Interest Payable. Interest, at the rate described
above, shall be payable ON DEMAND. Borrower may make whole or partial interest payments at any time prior to demand, without penalty
and without affecting any other provisions of this Note.

if this Note has not been paid in full, the Lender may, in its sole and absolute discretion, agree to convert the then outstanding principal
balance of this Note and all accrued interest thereon into the same security which is being issued by the Company in its next private
placement of equity or equity-backed securities launching after the date hereof.

other court in the State of New York as appropriate and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive.
Each of the parties hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Maker
hereby appoints Bill Chen of RedOne Investment Limited with offices at 667 Madison Avenue, New York, New York 10065 as its agent for service
of process, and agrees that service of any process, summons, notice or document upon such agent, by hand delivery or registered mail,

Remedies Cumulative. Each of the parties hereto acknowledges and agrees that, in the event of any breach of any covenant or agreement
contained in this Agreement by the other party, money damages may be inadequate with respect to any such breach and the non-breaching

other remedy to which they may be entitled at law or in equity, to seek injunctive relief and/or to compel specific performance to prevent
breaches by the other party hereto of any covenant or agreement of such other party contained in this Agreement. Accordingly, Maker hereby
agrees Buyer is entitled to an injunction prohibiting any conduct by the Maker in violation of this Agreement and Maker shall not seek
the posting of any bond in connection with such request for an injunction. Furthermore, in any action by Buyer to enforce this Agreement,
