 7. Parties in Interest, Transferability. This Note shall be binding
upon the Company and its successors and assigns and the terms hereof shall inure to the benefit of the Payee and its successors and permitted assigns. This Note may be transferred or sold, subject to the provisions of Section 16 of this Note, or

 10. Governing
Law. This Note shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to the choice of law provisions. This Note shall not be interpreted or construed with any presumption against
the party causing this Note to be drafted.

Headings. Article and section headings in this Note are included herein for purposes of convenience of reference only and shall not constitute a part of this Note for any other purpose.

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

 5 

 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 of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise
thereof or of any other right, power or privilege. 
  
 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 substitution or replacement therefore shall be stamped or imprinted with a legend in substantially the following form:

 17. Severability. The provisions of this Note are severable, and if
any provision shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall not in any manner affect such provision in any other jurisdiction or any other provision of this Note in any
jurisdiction. 
  
 18. Consent to Jurisdiction. Each of the
Company and the Payee (i) hereby irrevocably submits to the jurisdiction of the United States District Court sitting in the Southern District of New York and the courts of the State of New York located in New York county for the 
  

 6 

 purposes of any suit, action or proceeding arising out of or relating to this Note and (ii) hereby waives, and agrees not
to assert in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such court, that the suit, action or proceeding is brought in an inconvenient forum or that the venue of the suit, action or
proceeding is improper. Each of the Company and the Payee consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address set forth in Section 9 hereof and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing in this Section 18 shall affect or limit any right to serve process in any other manner permitted by law. 
  
 19. Company Waivers. Except as otherwise specifically provided herein, the Company and all others that may become
liable for all or any part of the obligations evidenced by this Note, hereby waive presentment, demand, notice of nonpayment, protest and all other demands and notices in connection with the delivery, acceptance, performance and enforcement of this
Note, and do hereby consent to any number of renewals of extensions of the time or payment hereof and agree that any such renewals or extensions may be made without notice to any such persons and without affecting their liability herein and do
further consent to the release of any person liable hereon, all without affecting the liability of the other persons, firms or Company liable for the payment of this Note, AND DO HEREBY WAIVE TRIAL BY JURY. 
  
 (a) No delay or omission on the part of the Payee in exercising its rights
under this Note, or course of conduct relating hereto, shall operate as a waiver of such rights or any other right of the Payee, nor shall any waiver by the Payee of any such right or rights on any one occasion be deemed a waiver of the same right
or rights on any future occasion. 
  
 (b) THE COMPANY
ACKNOWLEDGES THAT THE TRANSACTION OF WHICH THIS NOTE IS A PART IS A COMMERCIAL TRANSACTION, AND TO THE EXTENT ALLOWED BY APPLICABLE LAW, HEREBY WAIVES ITS RIGHT TO NOTICE AND HEARING WITH RESPECT TO ANY PREJUDGMENT REMEDY WHICH THE PAYEE OR ITS
