	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”)
entered into by and among Constellation Acquisition Corp I, a Cayman Islands exempted company (the “Company”),
and Deutsche Bank Securities, Inc. and Morgan Stanley & Co. LLC, as representatives (the “Representatives”)
of the several underwriters (each, an “Underwriter” and collectively, the “Underwriters”),
relating to an underwritten initial public offering (the “Public Offering”), of up to 34,500,000
of the Company’s units (including up to 4,500,000 units that may be purchased to cover over-allotments, if any) (the “Units”),
each comprised of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Class A
Ordinary Shares”), and one-third of one redeemable warrant. Each whole warrant (each, a “Warrant”)
entitles the holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment as
described in the Prospectus (as defined below). 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 New York Stock
Exchange. Certain capitalized terms used herein are defined in paragraph 12 hereof.

 

In order to induce the Company and the Underwriters 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, each of Constellation Sponsor GmbH & Co. KG, a German limited partnership
(the “Sponsor”) and the undersigned individuals, each of whom is, or will be, a member of the Company’s
board of directors and/or management team (each of the undersigned individuals, an “Insider” and collectively,
the “Insiders”), hereby agrees with the Company as follows:

 

		1.	The Sponsor and each Insider agrees that if the Company seeks shareholder approval of a proposed Business Combination, then
in connection with such proposed Business Combination, it, he or she shall (i) vote any Ordinary Shares (as defined below)
owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any Ordinary Shares owned by it,
him or her in connection with such shareholder 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 Ordinary Shares
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 shareholders in accordance
with the Company’s amended and restated memorandum and articles of association (as it may be amended from time to time, 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 ten (10) business
days thereafter, redeem 100% of the Class A Ordinary Shares 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
(as defined below), including interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of
interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely
extinguish all Public Shareholders’ (as defined below) rights as shareholders (including the right to receive further liquidating
distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of
the Company’s remaining shareholders and the Company’s

 

     

     

    

board of directors, dissolve and liquidate, subject
in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide for claims of
creditors and in all cases subject to the other requirements of applicable law. The Sponsor and each Insider agrees to not propose
any amendment to the Charter (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection
with our initial business combination or to redeem 100% of the Offering Shares if the Company does not complete a Business Combination
within the required time period set forth in the Charter or (B) with respect to any other material provisions relating to shareholders’
rights or pre-initial Business Combination activity, unless the Company provides its Public Shareholders 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 earned on the funds held in the Trust Account and not previously
released to the Company to pay its taxes, divided by the number of then outstanding Offering Shares.

 

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 or any other asset of the
Company 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 Ordinary Shares held by it, him or her, if any, any redemption rights it,
he or she may have in connection with (a) the consummation of a Business Combination, including, without limitation, any such
rights available in the context of a shareholder vote to approve such Business Combination, or (b) a shareholder vote to approve
an amendment to the Charter (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection
with our initial business combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business Combination
within the time period set forth in the Charter or (B) with respect to any other material provisions relating to shareholders’
rights or pre-initial Business Combination activity or in the context of a tender offer made by the Company to purchase Offering
Shares (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 the time period
set forth in the Charter).

 

		3.	The Sponsor and each Insider acknowledge and agree that prior to entering into a definitive agreement for a Business Combination
with a target business that is affiliated with the Sponsor, any of the Company’s founders, the Insiders or any other directors
or officers of the Company, the Company or a committee of independent directors must obtain an opinion from an independent investment
banking firm or an independent valuation or accounting firm that such Business Combination is fair to the Company from a financial
point of view.

 

		4.	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 Representatives, (i) sell, offer to sell, contract or
agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, 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
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations
of the Commission promulgated thereunder, with respect to, any Units, Ordinary Shares (including, but not limited to, Founder Shares),
Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, (ii) enter
into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
of any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or
exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery
of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in
clause (i) or (ii). Each of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any
release or waiver, of the restrictions set forth in this paragraph 4 or paragraph 8 below, the Company shall announce the impending
release or waiver by press release through a major news service at least two business

 

    2 

     

    

days before the effective date of the release or waiver.
Any release or waiver granted shall only be effective two business days after the publication date of such press release. 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.

 

		5.	In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination
within the time period set forth in the Charter, the Sponsor (the “Indemnitor”) 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) to which the Company may become subject as a result of any claim by (i) any third party for services
rendered or products sold to the Company or (ii) any prospective target business with which the Company has entered into a
written letter of intent, confidentiality or other similar agreement or Business Combination agreement (a “Target”);
provided, however, that such indemnification of the Company by the Indemnitor (x) shall apply only to the extent
necessary to ensure that such claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below
the lesser of (i) $10.00 per Offering Share and (ii) the actual amount per Offering Share held in the Trust Account as of
the date of the liquidation of the Trust Account, if less than $10.00 per Offering Share is then held in the Trust Account due
to reductions in the value of the trust assets, less taxes payable, (y) shall not apply to any claims by a third party or
a Target which executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable)
and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended. The Indemnitor 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 Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

 

		6.	To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 4,500,000 Units
within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Initial Shareholders agree to
forfeit, at no cost, a number of Founder Shares, to be split pro rata between them based on the number of Founder Shares they hold
upon the consummation of the Public Offering, equal to 1,125,000 multiplied by a fraction, (i) the numerator of which is 4,500,000
minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator
of which is 4,500,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by
the Underwriters so that the Founder Shares will represent an aggregate of 20% of the Company’s issued and outstanding Ordinary
Shares upon the consummation of the Public Offering . The Initial Shareholders further agree that to the extent that the size of
the Public Offering is increased or decreased, the Company will purchase or sell Units or effect a share repurchase or share capitalization,
as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the
Initial Shareholders prior to the Public Offering at 20% of its issued and outstanding Ordinary Shares upon the consummation of
the Public Offering. In connection with such increase or decrease in the size of the Public Offering, then (A) the references
to 4,500,000 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 Class A Ordinary Shares included in the Units issued in the Public Offering and (B) the reference
to 1,125,000 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of Founder Shares
that the Initial Shareholders would have to surrender to the Company in order for the Initial Shareholders to hold an aggregate
of 20% of the Company’s issued and outstanding Ordinary Shares upon the consummation of the Public Offering.

 

		7.	The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably
injured in the event of a breach by such Sponsor or an Insider of

 

    3 

     

    

its, his or her obligations under paragraphs 1, 2, 4,
5, 6, 8(a), and 8(b), 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.

		8.	(a) The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any Class A Ordinary
Shares 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 Class A Ordinary
Shares 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, amalgamation, capital stock exchange,
reorganization or other similar transaction that results in all of the Company’s Public Shareholders having the right to
exchange their shares of Class A Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up
Period”).

 

(b) The Sponsor, affiliates of the Sponsor and each
Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or any Class A Ordinary Shares underlying
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
8(a) and 8(b), Transfers of the Founder Shares, Private Placement Warrants and the Class A Ordinary Shares underlying the
Private Placement Warrants that are held by the Sponsor, affiliates of the Sponsor, any Insider or any of their permitted transferees
(that have complied with this paragraph 8(c)), are permitted (a) to the Company’s officers or directors, any affiliate
or family member of any of the Company’s officers or directors, any affiliate of the Sponsor or to any members of the Sponsor
or any of their affiliates; (b) in the case of an individual, by gift to a member of such individual’s immediate family
or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual
or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death
of such individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private
sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation
of an initial 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) by virtue of
the laws of the Cayman Islands or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; or (h) in
the event of the Company’s liquidation, merger, capital stock exchange or other similar transaction which results in all
of the Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other
property subsequent to the Company’s completion of an initial Business Combination; provided, however, that
in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement with the Company
agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Agreement (including provisions
relating to voting, the Trust Account and liquidating distributions).

 

		9.	The Sponsor and each Insider represents and warrants 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 and contains all of the information required to be disclosed pursuant to Item 401 of Regulation S-K, promulgated under
the Securities Act. The Sponsor and each Insider’s questionnaire furnished to the Company is true and accurate in all respects.
The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a

 

    4 

     

    

respondent in any legal action for, any injunction,
cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities
in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating
to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities
and it, he or she is not currently a defendant in any such criminal proceeding.

 

		10.	Except as disclosed in the Prospectus, neither the Sponsor nor any officer, nor any affiliate of the Sponsor or any officer,
nor any director of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, non-cash
payments, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered
in order to effectuate, the consummation of the Company’s initial Business Combination (regardless of the type of transaction
that it is), other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion
of the initial Business Combination: repayment of a loan and advances up to an aggregate of $250,000 made to the Company by the
Sponsor; payment to the Sponsor for certain office space, utilities, secretarial and administrative support services provided to
the Company and other expenses and obligations of the Sponsor as may be reasonably required by the Company for a total up to $10,000
per month; reimbursement for any reasonable out-of-pocket expenses related to identifying, investigating, negotiating and completing
an initial Business Combination, and repayment of loans, if any, and on such terms as to be determined by the Company from time
to time, made by the Sponsor or an affiliate of the Sponsor or any of the Company’s officers or directors to finance transaction
costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate an initial
Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such
loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $1,500,000 of such loans may be
convertible into warrants at a price of $1.50 per warrant at the option of the lender. Such warrants would be identical to the
Private Placement Warrants, including as to exercise price, exercisability and exercise period.

 

		11.	The Company, Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including,
without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this
Letter Agreement and, as applicable, to serve as an officer and/or director on the board of directors of the Company and hereby
consents to being named in the Prospectus as an officer and/or director of the Company.

 

		12.	As used herein, (i) “Business Combination” shall mean a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination, involving the Company and one or more businesses; (ii) “Ordinary

if the over-allotment option is not exercised by the Underwriters); (iv) “Initial Shareholders” shall
mean the Sponsor and any Insider that holds Founder Shares; (v) “Private Placement Warrants” shall mean
the 5,333,333 warrants (or 5,933,333 warrants if the over-allotment option is exercised in full) that affiliates of the Sponsor
have agreed to purchase for an aggregate purchase price of $8,000,000 (or $8,900,000 if the over-allotment option is exercised
in full), or $1.50 per warrant, in a private placement that shall occur simultaneously with the consummation of the Public Offering;
(vi) “Public Shareholders” shall mean the holders of securities issued in the Public Offering; (vii)
“Trust Account” shall mean the trust fund into which a portion of the net proceeds of the Public Offering
and the sale of the Private Placement Warrants shall be deposited; and (viii) “Transfer” shall mean the
(a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise
dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation
with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act, and the rules
and regulations of the Commission promulgated thereunder with respect to, any security, (b) entry into

 

    5

		13.	The Company will maintain an insurance policy or policies providing directors’ and officers’ liability insurance,
and each Director shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of
the coverage available pursuant to such policy or policies for any of the Company’s directors or officers.

 

		14.	This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter
hereof 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 changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except
by a written instrument executed by all parties hereto.

 

		15.	No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the
prior written consent of the other parties. 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 binding
on the Sponsor and each Insider and their respective successors, heirs and assigns and permitted transferees.

 

		16.	Nothing in this Letter Agreement shall be construed to confer upon, or give to, any person or corporation other than the parties

or agreement hereof. All covenants, conditions, stipulations, promises and agreements contained in this Letter Agreement shall
be for the sole and exclusive benefit of the parties hereto and their successors, heirs, personal representatives and assigns and
permitted transferees.

for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

 

		18.	This Letter Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall
not affect the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu

Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

 

		19.	This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York.
The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to,
this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit
to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive
jurisdiction and venue or that such courts represent an inconvenient forum.

 

		20.	Any notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement shall
be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested),
by hand delivery or facsimile transmission.

 

		21.	This Letter Agreement shall terminate on the earlier of (i) the expiration of the Lock-up Periods or (ii) the liquidation
of the Company; provided, however, that this Letter Agreement shall earlier

INVESTMENT MANAGEMENT TRUST AGREEMENT

 

This Investment Management
Trust Agreement (this “Agreement”) is made effective as of January 26, 2021 by and between Constellation
Acquisition Corp I, 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. 333-251974 (the “Registration Statement”) and prospectus
(the “Prospectus”) for the initial public offering (the “Offering”) of the
Company’s units (the “Units”), each of which consists of one Class A ordinary share, par value
$0.0001 per share (the “Ordinary Shares”), and one-third of one redeemable warrant, 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 Deutsche Bank Securities
Inc. and Morgan Stanley & Co. LLC, as representatives (the “Representatives”) of the several underwriters
(the “Underwriters”) named therein; and

 

WHEREAS,
as described in the Prospectus, $300,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as
defined in the Underwriting Agreement) (or $345,000,000 if the Underwriters’ over-allotment
option 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”); 

 

WHEREAS, pursuant to
the Underwriting Agreement, a portion of the Property equal to $16,500,000, or $18,975,000 if the Underwriters’ over-allotment
option is exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable by the Company
to the Underwriters 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 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) 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 solely 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; 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 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 Representatives 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 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, as applicable, signed on behalf of the Company by its Chief Executive Officer,
Chief Financial Officer, President, Executive Vice President, Vice President, Secretary or Chairman of the board of directors of
the Company (the “Board”) or other authorized officer of the Company, and, in the case of Exhibit
A, acknowledged and agreed to by the Representatives, 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 (less taxes payable and up to $100,000
of interest income 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 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 (less taxes payable and
up to $100,000 of interest income to pay dissolution expenses), shall be distributed to the Public Shareholders of record as of
such date;

 

(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 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 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 (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 “Shareholder Redemption Withdrawal Instruction”), the Trustee shall distribute
to the Public Shareholders on behalf of the Company the amount requested by the Company to be used to redeem Ordinary Shares from
Public Shareholders properly submitted in connection with a shareholder vote to approve an amendment to the Company’s amended
and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to
allow redemption in connection with our initial business combination or to redeem 100% of the Ordinary Shares included in the Units
sold in the Offering (the “public shares”) if the Company has not consummated an initial Business Combination
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 material provisions relating to shareholders’ rights or pre- initial Business Combination activity.
The written request of the

 

    2 

     

    

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 Chairman of the Board, Chief Executive
Officer, Chief Financial Officer, President, Executive Vice President, Vice President or Secretary. 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 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 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;

 

(e)  
Provide the Representatives 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 Representatives, 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 Representatives on behalf of the Underwriters prior to any transfer
of the funds held in the Trust Account to the Company or any other person;

 

    3 

     

    

(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; and

 

(h)  
Within four (4) business days after the Underwriters exercise the over-allotment option (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 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)  
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;

 

(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 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, 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

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

 

    4 

     

    

(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.

 

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 and has agreed to become subject
to the terms of 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, 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 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.

account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank.

		Re:	Trust
Account - Termination Letter

 

Dear Mr. Wolf and Ms. Gonzalez:

 

Pursuant to Section
1(i) of the Investment Management Trust Agreement between Constellation Acquisition Corp I (the “Company”)
and Continental Stock Transfer & Trust Company (“Trustee”), dated as of __________, 2021 (the “Trust
Agreement”), this is to advise you that the Company has entered into an agreement with ___________ (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 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 to a segregated account held by you on behalf of the Beneficiaries 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
Company shall direct on the Consummation Date (including as directed to it by the Representatives on behalf of the Underwriters
(with respect to the Deferred Discount)).

 

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 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, Co-Executive
Chairman or Vice Chairman, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders,
if a vote is held and (b) a joint written instruction signed by the Company and the Representatives with respect to the transfer
of the funds held in the Trust Account, including payment of amounts owed to public shareholders who have properly exercised their
redemption rights and payment of the Deferred Discount directly to the account or accounts directed by the Representatives 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. It is acknowledged and agreed that while the funds are on deposit in the trust account awaiting distribution, the Company will not earn
any interest or dividends.

 

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.
