 7. Parties in Interest, Transferability. This Note shall be binding

 12. Remedies, Characterizations, Other Obligations, Breaches and
Injunctive Relief. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note, at law or in equity (including, without limitation, a decree of specific performance and/or other
injunctive relief), no remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit a Payee’s right to pursue actual damages for any failure by the Company to
comply with the terms of this Note. Amounts set forth or provided for herein with respect to payments and the like (and the computation thereof) shall be the amounts to be received by the Payee and shall not, except as expressly provided herein, be
subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable and material harm to the Payee and that the remedy at law for any such
breach may be inadequate. Therefore the Company agrees that, in the event of any such breach or threatened breach, the Payee shall be entitled, in addition to all other available rights and remedies, at law or in equity, to seek and obtain such
equitable relief, including but not limited to an injunction restraining any such breach or threatened breach, without the necessity of showing economic loss and without any bond or other security being required.

 13. Failure or Indulgence Not Waiver. No failure or delay on the part of the Payee in the exercise

 14. Enforcement Expenses. The Company agrees to pay all
costs and expenses of enforcement of this Note, including, without limitation, reasonable attorneys’ fees and expenses. 
  
 15. Binding Effect. The obligations of the Company and the Payee set forth herein shall be binding upon the successors and assigns of each such
party, whether or not such successors or assigns are permitted by the terms hereof. 
  
 16. Compliance with Securities Laws. The Payee of this Note acknowledges that this Note is being acquired solely for the Payee’s own account and not as a nominee for any other party, and for investment,
and that the Payee shall not offer, sell or otherwise dispose of this Note other than in compliance with the laws of the United States of America and as guided by the rules of the Securities and Exchange Commission. This Note and any Note issued in
