 and expenses accrued, shall be due and payable on December 31, 2025 (the "Maturity Date").

2. All
 amounts outstanding from time to time hereunder shall bear interest at the rate of eleven percent (11%) per annum until such amounts
 are paid.

3. This
 Note may be prepaid in whole or in part without penalty or premium. All payments of principal shall be made in lawful money of the
 United States which shall be legal tender in payment of all debts, public and private, at the time of payment.

4. The
 Maker agrees to pay all costs of collection incurred in enforcing this Note, including attorneys' fees and costs at both trial
 and appellate levels and in any bankruptcy action. In the event any legal proceedings are instituted in connection with, or for the

 trial and appellate levels and in any bankruptcy action.

5. Each
 maker, endorser and guarantor or any person, firm or corporation becoming liable under this Note hereby consents to any extension
 or renewal of this Note or any part hereof, without notice, and agrees that they will remain liable under this Note during any extension
 or renewal hereof, until the debts represented hereby are paid in full.

6. All
 persons now or at any time liable for payment of this Note hereby waive presentment, protest, notice of protest and dishonor. The

 delay on the part of Payee in exercising any right or remedy hereunder shall operate as a waiver of such right or remedy. No single
 or partial exercise of a right or remedy shall preclude other or further exercise of that or any other right or remedy. The failure
 of Payee to insist upon strict performance of any term of this Note, or to exercise any right or remedy hereunder, shall not be construed

 is effective unless in writing executed by the Payee.

10. The
 unenforceability or invalidity of any provision of this Note as to any person or circumstances shall not render that provision or
