 Ladies and Gentlemen: 
 This letter

“IPO”) of the securities of Sarissa Capital Acquisition Corp. (the “Company”) and continuing until the earlier of (i) the consummation by the Company of an initial business combination and
(ii) the Company’s liquidation (in each case as described in the Registration Statement) (such earlier date hereinafter referred to as the “Termination Date”), Sarissa Capital Acquisition Sponsor LLC (the
“Sponsor”) shall take steps directly or indirectly to make available to the Company certain office space, secretarial and administrative services as may be required by the Company from time to time, situated at 660 Steamboat

Friday of the month (and if such day is not a business day, the following business day) and if there is a stub period for the first payment or the last payment, such amount shall be pro rated at a rate of $333.33/ day. The Company shall make all
payments by wire transfer of immediately available funds to an account designated by the Sponsor or by such other method as may be reasonably acceptable to the Sponsor. The Sponsor hereby agrees that it does not have any right, title, interest or
claim of any kind (a “Claim”) in or to any monies that may be set aside in a trust account (the “Trust Account”) that may be established in connection with and upon the consummation of the IPO and
hereby irrevocably waives any Claim it presently has or may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company and will not seek recourse, reimbursement, payment or satisfaction of any
Claim against the Trust Account or any monies or other assets in the Trust Account for any reason whatsoever. 
 This letter agreement
constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they
relate in any way to the subject matter hereof or the transactions contemplated hereby. 
 This letter agreement may not be amended,
modified or waived as to any particular provision, except by a written instrument executed by the parties hereto. 
 The parties may not
assign this letter agreement and any of their rights, interests, or obligations hereunder without the consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer
or assign any interest or title to the purported assignee. 
 This letter agreement shall be governed by, construed in accordance with, and
interpreted pursuant to the laws of the State of New York, without giving effect to its choice of laws principles that will apply the laws of another jurisdiction. 

This letter agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of
which together shall constitute one and the same agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this letter agreement.
