and which interest shall be net of any taxes payable, it being understood that the Trustee has no obligation to monitor or question
the Company’s position that an allocation has been made for taxes payable), only as directed in the Termination Letter and
the other documents referred to therein; provided, that, in the case a Termination Letter in the form of Exhibit A
is received, or (y) upon the date which is twenty-four (24) months after the closing of the Offering, or such later date
as may be approved by the Company’s stockholders in accordance with the Company’s amended and restated Certificate

    2


     


    







 


 


(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 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; provided, however, that to the extent there is not sufficient cash in the Trust Account
to pay such 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; provided, further, however, that if the tax to be paid is a franchise tax, the written
request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill for the Company (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 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

submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and restated Certificate
of Incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection
with the Company’s initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business
combination involving the Company and one or more businesses (a “Business Combination”) or to redeem 100% of
the Company’s public shares if the Company does not complete its initial Business Combination within twenty-four (24) months
from the closing of the Offering or (B) with respect to any other provision relating to stockholders’ rights or pre-initial
Business Combination activity. 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


 






    3


     


    

 


(l)                
Not make any withdrawals or distributions from the Trust Account other than pursuant to Sections 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 Chairman of the Board, President, Chief
Executive Officer, Chief Financial Officer, Chief Operating Officer, General Counsel, Secretary or other authorized officer of
the Company. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(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 outside 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 or its representatives’ 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; provided, further,
that the Company may conduct and manage the defense against any Indemnified Claim if the Trustee does not promptly take action
to mount such a defense. 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 the Property 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 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 hereto and as may be provided in Section 2(b) hereof;

Business Combination;

    5


     


    

 





(f)               
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 or its representatives’
gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order,

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,

Verify the accuracy of the information contained in the Registration Statement;

(j)

(k)              
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

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 and has agreed to become subject to the
terms of this Agreement (whether following the Trustee giving notice that it desires to resign under this Agreement or the Company
otherwise electing to replace the Trustee under this Agreement), the Trustee shall 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 and any other reasonable transfer requests the Company may make, 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;


 


(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); or


 


(c)              
If the Offering is not consummated within ten (10) business days of the date of this Agreement, in which case any funds received
by the Trustee from the Company or SSAC Alpha Sponsor, LLC, as applicable, for purposes of funding the Trust Account shall be promptly
returned to the Company or SSAC Alpha Sponsor, LLC, as applicable.


 


6.             Miscellaneous.

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 or its representatives’ gross negligence, fraud or willful misconduct,

transmission of the funds.


 


(b)

Re: Trust Account Termination Letter


 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of the Investment
Management Trust Agreement between Science Strategic Acquisition Corp. Alpha (the “Company”) and Continental
Stock Transfer & Trust Company (the “Trustee”), dated as of [•], 2021 (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 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 above-referenced 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 Credit Suisse
Securities (USA) LLC (the “Underwriter”) (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 the trust operating account at J.P.
Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor the Underwriter will earn any interest.


 


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, which verifies that the Business Combination has been approved by a vote of the Company’s
stockholders, if a vote is held and (b) joint written instruction signed by the Company and the Underwriter 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.


 



    E-A


     


    




 


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 the notice as soon thereafter as
possible.
