2. Events of Default.

(i) any default in the payment of the principal of this Note, as and when the same shall become due and payable;

(ii) Maker shall fail to observe or perform any obligation or shall breach any term or provision of this Note and such failure or breach shall not have been remedied within five calendar days after the date on which notice of such failure or breach shall have been delivered;

(iii) Maker shall commence, or there shall be commenced against Maker a case under any applicable bankruptcy or insolvency laws as now or hereafter in effect or any successor thereto, or Maker commences any other proceeding under any reorganization, arrangement, adjustment of debt, relief of debtors, insolvency or similar law of any jurisdiction whether now or hereafter in effect relating to Maker, or there is commenced against Maker any such bankruptcy, insolvency or other proceeding which remains undismissed for a period of 60 days; or Maker is adjudicated insolvent or bankrupt; or any order of relief or other order approving any such case or proceeding is entered; or Maker suffers any appointment of any custodian or the like for him or any substantial part of his property which continues undischarged or unstayed for a period of 60 days; or Maker makes a general assignment for the benefit of creditors; or Maker or any subsidiary shall by any act or failure to act expressly indicate its consent to, approval of or acquiescence in any of the foregoing; or any action is taken by Maker for the purpose of effecting any of the foregoing;

(b) If any Event of Default occurs, the full principal amount of this Note shall become, at the Payee’s election, (i) immediately due and payable in cash or (ii) be exchanged for an 8% Senior Convertible Note due July 21, 2025 identical to the Note issued by the Maker to the Payee on July 22, 2024. Commencing 5 days after the occurrence of any Event of Default that results in the acceleration of this Note, interest on this Note shall accrue at the rate of 12% per annum, or such lower maximum amount of interest permitted to be charged under applicable law. The Payee need not provide and Maker hereby waives any presentment, demand, protest or other notice of any kind, and the Payee may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Payee at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

3. No Waiver of Payee’s Rights. All payments of principal and interest (if any) shall be made without setoff, deduction or counterclaim. No delay or failure on the part of the Payee in exercising any of its options, powers or rights, nor any partial or single exercise of its options, powers or rights shall constitute a waiver thereof or of any other option, power or right, and no waiver on the part of the Payee of any of its options, powers or rights shall constitute a waiver of any other option, power or right. Maker hereby waives presentment of payment, protest, and all notices or demands in connection with the delivery, acceptance, performance, default or endorsement of this Note. Acceptance by the Payee of less than the full amount due and payable hereunder shall in no way limit the right of the Payee to require full payment of all sums due and payable hereunder in accordance with the terms hereof.

4. Modifications. No term or provision contained herein may be modified, amended or waived except by written agreement or consent signed by the party to be bound thereby.

5. Cumulative Rights and Remedies; Usury. The rights and remedies of Payee expressed herein are cumulative and not exclusive of any rights and remedies otherwise available under this Note or applicable law (including at equity). The election of Payee to avail itself of any one or more remedies shall not be a bar to any other available remedies, which Maker agrees Payee may take from time to time. If it shall be found that any interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall be reduced to the maximum permitted rate of interest under such law.

6. Severability. If any provision of this Note is declared by a court of competent jurisdiction to be in any way invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest.

7. Successors and Assigns. This Note shall be binding upon Maker and his heirs and successors and shall inure to the benefit of the Payee and its successors and assigns. The term “Payee” as used herein, shall also include any endorsee, assignee or other holder of this Note.
