Investor hereby represents and warrants to the Company and agrees as follows: 
 a. Such Investor is purchasing the Note (including the

 e. Such Investor understands that the Note (including the shares of Preferred Stock or
Common Stock, as applicable, issuable upon conversion of such Note) have not been registered under the Securities Act, or the securities or similar Laws of any jurisdiction, and is offered in reliance on exemptions therefrom, which reliance depends

f. Such Investor understands and agrees that (i) there are substantial restrictions on the transferability of the shares of Preferred
Stock or Common Stock, as applicable, issuable upon conversion of such Note, (ii) except as set forth in the Investors’ Rights Agreement, it has no rights to require its Equity Interests to be registered under the Securities Act or the

may not be possible for such Investor to liquidate its investment in the Company and (v) such Investor may have to hold its Note (including the shares of Preferred Stock or Common Stock, as applicable, issuable upon conversion of such Note) and
bear the economic risk of its investment therein indefinitely. 
 6.3 Foreign Investors. If such Investor is not a United States
person (as defined by Rule 902(k) under the Securities Act), such Investor hereby represents that it has satisfied itself as to the full observance of the Laws of its jurisdiction in connection with any invitation to subscribe for its respective
Note (including the shares of Preferred Stock or Common Stock, as applicable, issuable upon conversion of such Note) or any use of this Agreement, including (i) the Laws within its jurisdiction for the purchase of the Note (including the shares

(as defined by Rule 902(k) under the Securities Act), such Investor’s subscription and payment for, and such Investor’s beneficial ownership of, the Note (including the shares of Preferred Stock or Common Stock, as applicable, issuable
upon conversion of such Note) will not violate any applicable securities or other Laws of such Investor’s jurisdiction. 
 6.4
Brokers’ or Finders’ Fees. Such Investor has not employed, and is not liable for the payment of any fee to, any agent, finder, broker, consultant or similar Person in connection with the transactions contemplated under this

threshold for purposes of this Agreement. Any reference to a section or subsection in the Company Disclosure Schedules refers to that section or subsection of this Agreement, unless the context requires otherwise; provided, however, that a
particular matter disclosed in any section or subsection of the Company Disclosure Schedules that is reasonably apparent from a facial reading of such disclosure to qualify another section or subsection of this Agreement shall also be deemed to
qualify such other section or subsection of this Agreement. No disclosure in the Company Disclosure Schedules relating to any possible breach or violation of any agreement, Law or regulation shall be construed as an admission or indication against
interest to a third party that any such breach or violation exists or has actually occurred. 
 7.17 Massachusetts Business Trust. A
copy of the Agreement and Declaration of Trust of each Fidelity Investor, or any Affiliate thereof, is on file with the Secretary of State of the Commonwealth of Massachusetts, and notice is hereby given that this Agreement is executed on behalf of
the trustees of each such Investor or any Affiliate thereof as trustees and not individually and that the obligations of this Agreement are not binding on any of the trustees, officers or stockholders of such Investor or any Affiliate thereof
individually but are binding only upon such Investor or any Affiliate thereof and its assets and property. 
 7.18 Severability. If
any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such
determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as
possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.
