1. Amendment to Warrant. The Warrant is hereby amended by amending and restating Section 3(b) of the Warrant in its entirety as follows:

“b) Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be (i) if such Exercise occurs prior to the consummation of the Company’s first Public Offering, $8.2394 (or, if such Exercise occurs following or in connection with the conversion of the entire Convertible Amount (from inception of the Secured Promissory Note) into Conversion Shares, $8.1653; or (ii) if such Exercise occurs upon or following the consummation of the Company’s first Public Offering, the lower of (x) $8.1653 and (y) the initial public offering price per share of Common Stock in such Public Offering, in each case subject to the adjustment set forth in Section 4 hereto (the “Exercise Price”).”

2. Governing Law. This Amendment will be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any other jurisdiction other than the State of Delaware. In furtherance of the foregoing, the internal Laws of the State of Delaware will control the interpretation and construction of this Secured Promissory Note, even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

This Amendment shall become effective when all Parties hereto shall have received a counterpart hereof signed by the other Parties hereto. The Parties agree that the delivery of this Amendment may be effected by means of an exchange of electronic signatures with original copies to follow by mail or courier service.

5. Headings. Headings in this Amendment are included for reference only and shall have no effect upon the construction or interpretation of any part of this Amendment.

6. Severability. The illegality or unenforceability of any provision of this Amendment or any instrument or agreement required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Amendment or any instrument or agreement required hereunder.

7. Entire Agreement. This Amendment embodies the entire agreement and understanding among the parties hereto and supersedes all prior or contemporaneous agreements and understandings of such parties, verbal or written, relating to the subject matter hereof.
