Re: Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be
entered into by and among Science Strategic Acquisition Corp. Alpha, a Delaware corporation (the “Company”),
and Credit Suisse Securities (USA) LLC (the “Underwriter”), relating to an underwritten initial public offering
(the “Public Offering”) of 31,050,000 of the Company’s units (including up to 4,050,000 units that may
be purchased to cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s
Class A common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one redeemable warrant.
Each whole Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Common Stock at
a price of $11.50 per share, subject to adjustment. The Units will be sold in the Public Offering pursuant to a registration statement
on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission
(the “Commission”), and the Company has applied to have the Units listed on the Nasdaq Capital Market. Certain
capitalized terms used herein are defined in paragraph 11 hereof.

 

In order to induce the Company and the Underwriter
to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, SSAC Alpha Sponsor, LLC (the “Sponsor”) and each
of the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each,
an “Insider” and collectively, the “Insiders”), hereby severally (and not jointly and severally)
agrees with the Company as follows:

 

1.                 
The Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then
in connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him
or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in
connection with such stockholder approval. If the Company seeks to consummate a proposed Business Combination by engaging in a
tender offer, the Sponsor and each Insider agrees that it, he or she will not sell or tender any shares of Capital Stock owned
by it, him or her in connection therewith.

 

2.                  The
Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within
24 months from the closing of the Public Offering, or such later period approved by the Company’s stockholders in
accordance with the Company’s amended and restated certificate of incorporation (the “Charter”), the
Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the
purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter, subject to
lawfully available funds therefor, redeem 100% of the Common Stock sold as part of the Units in the Public Offering (the
“Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest
shall be net of taxes payable), divided by the number of then issued and outstanding Offering Shares, which redemption will
completely extinguish all Public Stockholders’ rights as stockholders (including the right to receive further
liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such
redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors,
dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of
creditors and other requirements of applicable law. The Sponsor and each Insider agree to not propose any amendment to the
Charter that would modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if
the Company does not complete a Business Combination within 24 months from the closing of the Public Offering, or with
respect to any other material provisions relating to stockholders’ rights or pre-initial business combination activity,
unless the Company provides its Public Stockholders with the opportunity to redeem their Offering Shares upon approval of any
such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account,
including interest (which interest shall be net of taxes payable), divided by the number of then issued and outstanding
Offering Shares.

 

    1

     

    

 

The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account as a result
of any liquidation of the Company with respect to the Founder Shares held by it, him or her. The Sponsor and each Insider hereby
further waives, with respect to any shares of Common Stock held by it, him or her, if any, any redemption rights it, he or she
may have in connection with (x) the consummation of a Business Combination, including, without limitation, any such rights available
in the context of a stockholder vote to approve such Business Combination or in the context of a tender offer made by the Company
to purchase shares of Common Stock and (y) a stockholder vote to approve an amendment to the Charter (i) to modify the substance
or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination
within 24 months of the closing of the Public Offering or (ii) with respect to any other provision relating to stockholders’
rights or pre-initial business combination activity (although the Sponsor, the Insiders and their respective affiliates shall be
entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate
a Business Combination within 24 months from the closing of the Public Offering ).

 

3.                  
Notwithstanding the provisions set forth in paragraphs 7(a) and (b) below, during the period commencing on the effective date
of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior
written consent of the Underwriter, offer, sell, contract to sell, pledge or otherwise dispose of (or enter into any
transaction that is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition
or effective economic disposition due to cash settlement or otherwise)), directly or indirectly, or establish or increase a
put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16
(“Section 16”) of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the
Commission promulgated thereunder, with respect to, any Units, shares of Capital Stock, Warrants or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock, or publicly announce an intention to effect
any such transaction; provided, however, that the foregoing does not apply to the forfeiture of any Founder
Shares pursuant to their terms or any transfer of Founder Shares to any current or future independent director of the Company
(as long as such current or future independent director transferee is subject to this Letter Agreement or executes an
agreement substantially identical to the terms of this Letter Agreement, as applicable to directors and officers at the time
of such transfer; and as long as, to the extent any Section 16 reporting obligation is triggered as a result of such
transfer, any related Section 16 filing includes a practical explanation as to the nature of the transfer). The provisions of
this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the
transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the
duration that such terms remain in effect at the time of the transfer.

 

    2

     

    

 

4.                  In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any
other shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all
loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses
reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any
claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party for services
rendered (other than the Company’s independent registered public accountants) or products sold to the Company or (ii) a
prospective target business with which the Company has discussed entering into a transaction agreement (a
“Target”); provided, however, that such indemnification of the Company by the
Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other
than the Company’s independent registered public accountants) or products sold to the Company or a Target do not reduce
the amount of funds in the Trust Account to below (i) $10.00 per Offering Share or (ii) such lesser amount per Offering Share
held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust
assets, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay
taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust
Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to
be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third
party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably
satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor
notifies the Company in writing that it shall undertake such defense. For the avoidance of doubt, none of the Company’s
officers or directors will indemnify the Company for claims by third parties, including, without limitation, claims by
vendors and prospective target businesses.

 

    3

     

    

 

5.                 
To the extent that the Underwriter does not exercise its over-allotment option to purchase up to an additional 4,050,000
Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit,
at no cost, a number of Founder Shares in the aggregate equal to the product of 1,012,500 multiplied by a fraction, (i) the numerator
of which is 4,050,000 minus the number of Units purchased by the Underwriter upon the exercise of its over-allotment option, and
(ii) the denominator of which is 4,050,000. The forfeiture will be adjusted to the extent that the over-allotment option is not
exercised in full by the Underwriter so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s issued
and outstanding shares of Capital Stock after the Public Offering. To the extent that the size of the Public Offering is increased
or decreased, the Company will effect a capitalization or share repurchase, redemption or stock split or other appropriate mechanism,
as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the
Capital Stock of the Initial Stockholders prior to the Public Offering at 20.0% of the Company’s issued and outstanding Capital
Stock upon the consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering,
(A) references to 4,050,000 in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed
to a number equal to 15% of the number of shares included in the Units issued in the Public Offering and (B) the reference to 1,012,500
in the formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Sponsor
would have to return to the Company in order to hold (with all of the Initial Stockholders) an aggregate of 20.0% of the Company’s
issued and outstanding Capital Stock after the Public Offering.

 

6.                 
(a)         The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriter and the Company would be irreparably
injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a),
7(b), and 9, as applicable, of this Letter Agreement, (ii) monetary damages may not be an adequate remedy for such breach and (iii)
the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law
or in equity, in the event of such breach.

 

7.                  (a)         The
Sponsor and each Insider agree that it, he or she shall not Transfer (as defined below) any Founder Shares (or shares of
Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s
initial Business Combination and (B) subsequent to the Business Combination, (x) if the closing price of the Common Stock
equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the
like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial
Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange,
reorganization or other similar transaction that results in all of the Company’s stockholders having the right to
exchange their shares of Common Stock for cash, securities or other property (the “Founder Shares Lock-up
Period”).

 

    4

     

    

 

(b)             
The Sponsor and each Insider agree that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common
Stock issued or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion of a Business
Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period,
the “Lock-up Periods”).

 

(c)              
Notwithstanding the provisions set forth in paragraphs 3 and 7(a) and (b), Transfers of the Founder Shares, Private Placement
Warrants and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the
Founder Shares and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this
paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the
Company’s officers or directors, the Sponsor, any members of the Sponsor, or any affiliates of the Sponsor; (b) in the case
of an individual, transfers by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which
is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in
the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case
of an individual, transfers pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection
with the consummation of a Business Combination at prices no greater than the price at which the securities were originally purchased;
(f) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) in the case
of an entity, by virtue of the laws of its jurisdiction or its organizational documents or operating agreement; or (h) in the event
of the Company’s completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results
in all of the Company’s public stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property subsequent to the completion of the initial Business Combination; provided, however, that, in the
case of clauses (a) through (e), these permitted transferees must enter into a written agreement with the Company agreeing to be
bound by the transfer restrictions herein.

 

8.                  The
Sponsor and each Insider represent and warrant that it, he or she has never been suspended or expelled from membership in any
securities or commodities exchange or association or had a securities or commodities license or registration denied,
suspended or revoked. Each Insider’s biographical information furnished to the Company (including any such information
included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to
the Insider’s background. Each Insider’s questionnaire furnished to the Company is true and accurate in all

involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to

(e)           As soon as practicable, notify the Company and the Underwriter 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 tax returns relating to assets held in the Trust Account or in connection with the preparation
or completion of the audit of the Company’s financial statements by the Company’s auditors;

 

(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 after (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 signed on behalf of the Company by its Chief Executive Officer, President, Chief Financial
Officer, Chief Operating Officer, General Counsel, Secretary or Chairman of the board of directors of the Company (the
“Board”) or other authorized officer of the Company, and complete the liquidation of the Trust Account and
distribute the Property in the Trust Account, including interest (less up to $100,000 of interest that may be released to the
Company to pay dissolution expenses 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 of Incorporation, as it may be amended from time to time, 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 (less up to $100,000 of interest that may be released to the Company to pay dissolution
expenses and which interest shall be net of any taxes payable), shall be distributed to the Public Stockholders of record as
of such date;

 

    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
as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of

(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

 

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

 

    3 

     

    

 

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;

 

    4 

     

    

 

(d)           In connection with any vote of the Company’s stockholders regarding a Business Combination, provide to the Trustee an affidavit
or certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders regarding such
Business Combination;

 

(e)           Provide the Underwriter 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)            Expressly provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination Letter in the
Form of Exhibit A that the Deferred Discount be paid directly to the account or accounts directed by the Underwriter; and

 

(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.

 

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 party except for liability arising out of the Trustee’s or its representatives’ 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 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 reasonably incurred
and documented expenses incident thereto;

 

(d)           Refund any depreciation in principal of any Property;

 

(e)           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 

     

    

 

(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, 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;

  

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

 

(h)           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;

 

(i)            File information returns with respect to the Trust Account with any local, state or federal taxing 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;

 

(j)            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, franchise and income tax obligations, except pursuant to Section 1(j) hereof; or

 

(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 Account.

 

    6 

     

    

 

5.             Termination; Replacement of Trustee. 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 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.

 

(a)           The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below 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 or its representatives’ gross negligence, fraud or willful misconduct,
the Trustee shall not be liable for any loss, liability or out-of-pocket 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.

 

    7 

     

    

 

(c)           This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof.
Except for Sections 1(i), 1(j) and 1(k) hereof (which may not be modified, amended or deleted without the affirmative vote of sixty
five percent (65%) of the then outstanding shares of Common Stock and Class B common stock, par value $0.0001 per share, of the
Company voting together as a single class; provided that no such amendment will affect any Public Stockholder who has otherwise
indicated its election to redeem its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement),
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.

New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING

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 January 25, 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.
