INVESTMENT MANAGEMENT TRUST AGREEMENT 

This Investment Management Trust Agreement (this “Agreement”) is made effective as of October 20, 2020 by and between
Sarissa Capital Acquisition Corp., a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Trustee”). 

WHEREAS, the Company’s registration statement on Form S-1, File
No. 333-249171 (the “Registration Statement”) and prospectus (the “Prospectus”) for the initial public offering of the Company’s units (the
“Units”), each of which consists of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one-third of
one redeemable warrant, each whole warrant entitling the holder thereof to purchase one Ordinary Share (such initial public offering hereinafter referred to as the “Offering”), has been declared effective as of the date
hereof by the U.S. Securities and Exchange Commission; and 
 WHEREAS, the Company has entered into an Underwriting Agreement (the
“Underwriting Agreement”) with Cantor Fitzgerald & Co., as representative (the “Representative”) of the underwriters (the “Underwriters”); and 

WHEREAS, as described in the Prospectus, $175,000,000 of the gross proceeds of the Offering and sale of the Placement Warrants (as defined in
the Underwriting Agreement) (or $201,250,000 if the Underwriter’s over-allotment option to purchase additional Units is exercised in full) will be delivered to the Trustee to be deposited and held in a segregated trust account located at all
times in the United States (the “Trust Account”) for the benefit of the Company and the holders of the Ordinary Shares included in the Units issued in the Offering as hereinafter provided (the amount to be delivered to the
Trustee (and any interest subsequently earned thereon) is referred to herein as the “Property,” the shareholders for whose benefit the Trustee shall hold the Property will be referred to as the “Public
Shareholders,” and the Public Shareholders and the Company will be referred to together as the “Beneficiaries”); and 

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $6,125,000, or $7,043,750 if the Underwriter’s
over-allotment option to purchase additional Units is exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable by the Company to the Underwriter upon and concurrently with the consummation of the
Business Combination (as defined below) (the “Deferred Discount”); and 
 WHEREAS, the Company and the Trustee
desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property. 
 NOW
THEREFORE, IT IS AGREED: 
 1. Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

(a) Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the
Trustee located in the United States at J.P. Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) in the United States, maintained by the Trustee and at a brokerage institution
selected by the Trustee that is reasonably satisfactory to the Company; 












 (b) Manage, supervise and administer the Trust Account subject to the terms and conditions
set forth herein; 
 (c) In a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States
government securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and
(d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations, as determined by the Company; the
Trustee may not invest in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or
other consideration; 
 (d) Collect and receive, when due, all principal, interest or other income arising from the Property, which shall
become part of the “Property,” as such term is used herein; 
 (e) Promptly notify the Company and the Representative
of all communications received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply any necessary
information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account; 

(g) Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when
instructed by the Company to do so; 
 (h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust
Account reflecting all receipts and disbursements of the Trust Account; 
 (i) Commence liquidation of the Trust Account only after and
promptly following (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or
Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer, Chief Financial Officer or other authorized officer of the Company and in the case of Exhibit A, acknowledged and agreed to by the Representative, and
complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its income taxes, if any (less up to
$100,000 of interest to pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein, or (y) upon the date which is the later of (1) 24 months after the closing of the Offering and
(2) such later date as may be 

  
 2 













 
approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, if a Termination Letter has not been received by the
Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest earned on
the funds held in the Trust Account and not previously released to the Company to pay its income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), shall be distributed to the Public Shareholders of record as of such date.
It is acknowledged and agreed that there should be no reduction in the principal amount per share initially deposited in the Trust Account; 

(j) Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as
Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any income tax
obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the
Company shall forward such payment to the relevant taxing authority, so long as there is no reduction in the principal amount per share initially deposited in the Trust Account; provided, however, that to the extent there is not
sufficient cash in the Trust Account to pay such income tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution, so long as there is no reduction in
the principal amount per share initially deposited in the Trust Account (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The written request of
the Company in the form of Exhibit C referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; 

(k) Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as
Exhibit D (a “Shareholder Redemption Withdrawal Instruction”), the Trustee shall distribute to the remitting brokers on behalf of Public Shareholders redeeming Ordinary Shares the amount required to be used to redeem
the Ordinary Shares from Public Shareholders, such request to be properly submitted in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association to (a) modify
the substance or timing of the Company’s obligation to redeem 100% of the Ordinary Shares (the “public shares”) if the Company has not consummated an initial Business Combination (as defined below) within such time as is described in
the Company’s amended and restated memorandum and articles of association or (b) with respect to any other provision relating to the rights of holders of the Company’s Ordinary Shares. The written request of the Company referenced
above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and 

(l) Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j)
or (k) above.

 2. Agreements and Covenants of the Company. The Company hereby agrees and covenants
to: 
 (a) Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chief Executive Officer, Chief Financial
Officer or other authorized officer of the Company. In addition, except with respect to its duties under Sections 1(i), (j) and (k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any
verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such
instructions in writing; 
 (b) Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee
from and against any and all reasonable and documented expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit or
other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned
on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or
proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified
Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent
shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld. The Company may participate in such action with
its own counsel; 
 (c) Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual
administration fee, and transaction processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees unless and until it is distributed to
the Company pursuant to Sections 1(i) through 1(j) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of the Offering. The Trustee shall refund to the
Company the annual administration fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this
Section 2(c), Schedule A and as may be provided in Section 2(b) hereof; 
 (d) In
connection with any vote of the Company’s shareholders regarding a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Company and one or more businesses (the
“Business Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for the shareholder meeting verifying the vote of such shareholders regarding such Business Combination; 

  
 4 













 (e) Provide the Representative with a copy of any Termination Letter(s) and/or any other
correspondence that is sent to the Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same; 

(f) Unless otherwise agreed between the Company and the Representative, ensure that any Instruction Letter (as defined in Exhibit A)
delivered in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid directly to the account or accounts directed by the Representative on behalf of the Underwriters prior to any
transfer of the funds held in the Trust Account to the Company or any other person; 
 (g) Instruct the Trustee to make only those
distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement; 

(h) Within five (5) business days after the Underwriters exercise the over-allotment option to purchase additional Units (or any
unexercised portion thereof) or such over-allotment option expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount. 

3. Limitations of Liability. The Trustee shall have no responsibility or liability to: 

(a) Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement
and that which is expressly set forth herein; 
 (b) Take any action with respect to the Property, other than as directed in
Section 1 hereof, and the Trustee shall have no liability to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct; 

(c) Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of
any kind with respect to, any of the Property unless and until it shall have received written instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any
expenses incident thereto; 
 (d) Change the investment of any Property, other than in compliance with Section 1
hereof; 
 (e) Refund any depreciation in principal of any Property; 

(f) Assume that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee; 

  
 5 













 (g) The other parties hereto or to anyone else for any action taken or omitted by it, or any
action suffered by it to be taken or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon
any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee with written notification to the Company, which counsel may be the Company’s counsel), statement, instrument, report or other paper or
document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable care, to
be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced
by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior written consent thereto; 

(h) Verify the accuracy of the information contained in the Registration Statement; 

(i) Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as contemplated
by the Registration Statement;

authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(k) Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and
activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, income tax obligations, except pursuant to Section 1(j) hereof; or

 (l) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections
1(i), 1(j) or 1(k) hereof. 
 4. Trust Account Waiver. The Trustee has no right of
set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the
Trust Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section 2(b) or
Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account. 

5. Termination. This Agreement shall terminate as follows: 

(a) If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to
become subject to the terms of this Agreement, the Trustee shall 

  
 6 













 
transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon
this Agreement shall terminate; provided, however, that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an
application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or

 (b) At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with the provisions
of Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Section 2(b). 

6. Miscellaneous. 
 (a) The
Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth herein with respect to funds transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential
information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained access to such confidential information, or of any change
in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including account names, account numbers, and all other identifying information relating to a Beneficiary,
Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or expense resulting from any error in
the information or transmission of the funds. 
 (b) This Agreement shall be governed by and construed and enforced in accordance with the
laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. 

(c) This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for
(i) Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted without the affirmative vote of two-thirds or more of the shares
voted of the then outstanding Ordinary Shares and Class B ordinary shares, par value $0.0001 per share, of the Company, voting together as a single class; provided that no such amendment will affect any Public Shareholder who has
properly elected to redeem his or her Ordinary Shares in connection with a shareholder vote to amend this Agreement (A) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Public Shares in
connection with an initial Business Combination or an Amendment or to redeem 100% of its Ordinary Shares if the Company does not complete its initial Business Combination within the time frame specified in the Company’s amended and restated
memorandum and articles of association or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity) and
(ii) Section 1(i) hereof (which section additionally may not be modified, amended or deleted without the prior written consent of the Representative), this Agreement or any provision hereof may only be changed, amended or modified (other
than to correct a typographical error) by a writing signed by each of the parties hereto.

	 	Re:	 Trust Account - Termination Letter 



Mr. Wolf and Ms. Gonzalez: 
 Pursuant to
Section 1(i) of the Investment Management Trust Agreement between Sarissa Capital Acquisition Corp. (the “Company”) and Continental Stock Transfer & Trust Company
(“Trustee”), dated as of October 20, 2020 (the “Trust Agreement”), this is to advise you that the Company has entered into an agreement with [insert name] (the “Target
Business”) to consummate a business combination with Target Business (the “Business Combination”) on or about [insert date]. The Company shall notify you at least
seventy-two (72) hours in advance of the actual date (or such shorter time period as you may agree) of the consummation of the Business Combination (the “Consummation Date”).
Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement. 
 In accordance with the terms of
the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds into the trust operating account at J.P. Morgan Chase Bank, N.A. to the effect that, on the Consummation Date,
all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Representative (with respect to the Deferred Discount) and the Company shall direct on the Consummation Date. It is
acknowledged and agreed that while the funds are on deposit in said trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor the Representative will earn any interest or dividends. 

On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been
consummated, or will be consummated substantially concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”), and (ii) the Company shall deliver to you (a) a certificate
of the Chief Executive Officer, Chief Financial Officer or other authorized officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders, if a vote is held and (b) joint
written instruction signed by the Company and the Representative with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction
Letter”). You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter. In
the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in
the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations
under the Trust Agreement shall be terminated. 

  
 12 













 In the event that the Business Combination is not consummated on the Consummation Date
described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall
be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as set forth in such notice as soon thereafter as possible.
