2.           Representations
and Warranties.

 

(a)         The
Sponsor and each Insider, with respect to itself, herself or himself, represent and warrant to the Company that it, she or he has
the full right and power, without violating any agreement to which it, she or he is bound (including, without limitation, any non-competition
or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement, as applicable, and to
serve as an officer of the Company and/or a director on the Company’s Board of Director (the “Board”),
as applicable, and each Insider hereby consents to being named in the Prospectus, road show and any other materials as an officer
and/or director of the Company, as applicable.

 

(b)          Each
Insider represents and warrants, with respect to herself or himself, that such Insider’s biographical information furnished
to the Company (including any such information included in the Prospectus) is true and accurate in all material respects and does
not omit any material information with respect to such Insider’s background. The Insider’s questionnaire furnished
to the Company is true and accurate in all material respects. Each Insider represents and warrants that such Insider is not subject
to or a 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; such Insider 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 such Insider is not currently a defendant in
any such criminal proceeding; and such Insider 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.

 

3.            Business
Combination Vote. It is acknowledged and agreed that the Company shall not enter into a definitive agreement regarding a proposed
Business Combination without the prior consent of the Sponsor.  The Sponsor and each Insider, with respect to itself or herself
or himself, agrees that if the Company seeks stockholder approval of a proposed initial Business Combination, then in connection
with such proposed initial Business Combination, it, she or he, as applicable, shall vote all Founder Shares and any Public Shares
held by it, her or him, as applicable, in favor of such proposed initial Business Combination (including any proposals recommended
by the Board in connection with such Business Combination) and not redeem any Public Shares held by it, her or him, as applicable,
in connection with such stockholder approval.

 

4.            Failure
to Consummate a Business Combination; Trust Account Waiver.

 

(a)          The
Sponsor and each Insider hereby agree, with respect to itself, herself or himself, that in the event that the Company fails to
consummate its initial Business Combination within the time period set forth in 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, redeem 100% of the Public Shares, 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 release to the Company to pay income taxes (less up to $100,000 of interest to pay
dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public
Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as
promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders
and the Board, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations
under Delaware law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The
Sponsor and each Insider agree not to propose any amendment to the Charter (i) that would modify the substance or timing of
the Company’s obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with
an initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete an initial Business Combination
within the required time period set forth in the Charter or (ii) with respect to any provision relating to the rights of holders
of Public Shares unless the Company provides its Public Stockholders with the opportunity to redeem their Public 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 taxes, if any,
divided by the number of then-outstanding Public Shares.

 

    2

     

    

 

(b)         The
Sponsor and each Insider, with respect to itself, herself or himself, acknowledges that it, she or he 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, her or him, if any. The Sponsor and each of the Insiders hereby further waive, with respect to any
Founder Shares and Public Shares held by it, her or him, as applicable, any redemption rights it, she or he may have in connection
with 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 a stockholder vote to approve an amendment to the Charter (i) that would modify
the substance or timing of the Company’s obligation to provide holders of the Public Shares the right to have their shares
redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated
an initial Business Combination within the time period set forth in the Charter or (ii) with respect to any provision relating
to the rights of holders of Public Shares (although the Sponsor and the Insiders shall be entitled to liquidation rights with respect
to any Public Shares they hold if the Company fails to consummate a Business Combination within the required time period set forth
in the Charter).

 

5.           Lock-up;
Transfer Restrictions.

 

(a)         The
Sponsor and the Insiders agree that they shall not Transfer any Founder Shares (the “Founder Shares Lock-up”)
until the earlier of (A) one year after the completion of an initial Business Combination and (B) the date following
the completion of an initial Business Combination 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 Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”). Notwithstanding
the foregoing, if, subsequent to a Business Combination, 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
a 30-trading day period commencing at least 150 days after the Company’s initial Business Combination, the Founder Shares
shall be released from the Founder Shares Lock-up.

 

(b)         The
Sponsor and Insiders agree that they shall not effectuate any Transfer of Private Placement Warrants or Common Stock underlying
such warrants until 30 days after the completion of an initial Business Combination.

 

(c)           Notwithstanding
the provisions set forth in paragraphs 5(a) and (b), Transfers of the Founder Shares, Private Placement Warrants
and Common Stock underlying the Private Placement Warrants are permitted (a) to the Company’s employees, officers or
directors, any affiliates or family members of any of the Company’s officers or directors, any employees, officers, directors
or members of the Sponsor (or former Sponsor if such transfer occurs after a dissolution of the Sponsor) or their affiliates, or
any affiliates of the Sponsor (or former Sponsor if such transfer occurs after a dissolution of the Sponsor); (b) in the case
of an individual, by gift to a member of one of the individual’s immediate family, an estate planning vehicle or to a trust,
the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable
organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the 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 the consummation of a Business Combination at prices no greater than the price at which the Founder Shares,
Private Placement Warrants or Common Stock, as applicable, were originally purchased; (f) by pro rata distributions from the
Sponsor to its members, partners, or shareholders pursuant to the Sponsor’s organizational documents; (g) by virtue
of the laws of Delaware or the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (h) to
the Company for no value for cancellation in connection with the consummation of an initial Business Combination, (i) in the
event of the Company’s liquidation prior to the completion of a Business Combination; or (j) in the event of completion
of a liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of the Company’s
Public Stockholders having the right to exchange their Common Stock for cash, securities or other property subsequent to the completion
of an initial Business Combination; provided, however, that in the case of clauses (a) through (g) these
permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.

 

(d)            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, Transfer any Units, Common Stock, Warrants or
any other securities convertible into, or exercisable or exchangeable for, Common Stock held by it, her or him, as applicable,
subject to certain exceptions enumerated in Section 6(h) of the Underwriting Agreement.

 

    3

     

    

 

6.           Remedies.
The Sponsor and each of the Insiders hereby agree and acknowledge that (i) each of the Underwriters and the Company would
be irreparably injured in the event of a breach by the Sponsor or such Insider of its, her or his obligations, as applicable under
paragraphs 3, 4, 5, 7, 10 and 11, (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.           Payments
by the Company. Except as disclosed in the Prospectus, neither the Sponsor nor any affiliate of the Sponsor nor any director
or officer of the Company nor any affiliate of the officers shall receive from the Company any finder’s fee, reimbursement,
consulting fee, monies in respect of any payment 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).

 

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

 

9.           Termination.
This Letter Agreement shall terminate on the earlier of (i) the expiration of the Founder Shares Lock-up Period and (ii) the
liquidation of the Company.

 

10.          Indemnification.
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 (except for the Company’s independent auditors) or (ii) any 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 Indemnitor (x) shall apply only to the extent necessary to
ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount
of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public
Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due
to reductions in the value of the trust assets, in each case net of interest that may be withdrawn to pay the Company’s tax
obligations, (y) shall not apply to any claims by a third party or Target who 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.

 

11.          Forfeiture
of Founder Shares. To the extent that the Underwriters do not exercise their option to purchase additional Units within 45
days from the date of the Prospectus in full (as further described in the Prospectus), the Sponsor agrees to automatically surrender
to the Company for no consideration, for cancellation at no cost, an aggregate number of Founder Shares so that the number of Founder
Shares will equal of 20% of the sum of the total number of Common Stock and Founder Shares outstanding at such time. The Sponsor
and Insiders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will
effect a stock split, stock dividend, reverse stock split or stock repurchase, as applicable, with respect to the Founder Shares
immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at 20%
of the sum of the total number of Common Stock and Founder Shares outstanding at such time.

 

12.          Entire
Agreement. 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.

 

    4

     

    

 

13.         Assignment.
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, each of the Insiders and each of their respective successors, heirs, personal representatives and assigns and permitted
transferees.

 

14.          Counterparts.
This Letter Agreement may be executed in any number of original or facsimile counterparts, and each of such counterparts shall
for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

 

15.          Effect
of Headings. The paragraph headings herein are for convenience only and are not part of this Letter Agreement and shall not
affect the interpretation thereof.

 

16.          Severability.
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 of
any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Letter
Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

 

17.          Governing
Law. This Letter 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. 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.

 

18.           Notices.
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),

(this “Agreement”) is made effective as of January [   ], 2021 by and between One Equity Partners
Open Water I Corp., a Delaware corporation (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. 333-251925 (the “Registration Statement”) and prospectus (the
 “Prospectus”) for the initial public offering of the Company’s units (the “Units”),
each of which consists of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Common
Stock”), and one-third of one warrant, each whole warrant entitling the holder thereof to purchase one share
of Common Stock (such initial public offering hereinafter referred to as the “Offering”), has been declared
effective as of the date hereof by the U.S. Securities and Exchange Commission; and

 

WHEREAS, the Company has entered into an
Underwriting Agreement (the “Underwriting Agreement”) with Credit Suisse Securities (USA) LLC and RBC
Capital Markets, LLC, as representatives (the “Representatives”) to 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 Underwriter’s option to purchase additional units is exercised in full) will be delivered to the
Trustee to be deposited and held in a segregated trust account located at all times in the United States (the “Trust
Account”) for the benefit of the Company and the holders of shares of Common Stock 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 stockholders for whose benefit the Trustee shall
hold the Property will be referred to as the “Public Stockholders,” and the Public Stockholders
and the Company will be referred to together as the “Beneficiaries”); and

 

WHEREAS, pursuant to the Underwriting Agreement,
a portion of the Property equal to $10,500,000, or $12,075,000 if the Underwriter’s option to purchase additional units is

Underwriter upon 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) in the United States, maintained by Trustee and at a brokerage institution selected by the Trustee
that is reasonably satisfactory to the Company;

 

(b)            Manage,
supervise and administer the Trust Account subject to the terms and conditions set forth herein;

 

(c)            In
a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States government securities
within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or
less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7
promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government
treasury obligations, as determined by the Company; the Trustee may not invest in any other securities or assets, it being understood
that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder
and the Trustee may earn bank credits or other consideration;

 

    

     

    

 

(d)            Collect
and receive, when due, all principal, interest or other income arising from the Property, which shall become part of the “Property,”
as such term is used herein;

 

(e)            Promptly
notify the Company and the 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 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 earned on the funds held in the Trust Account and not previously
released to us to pay our income taxes (less up to $100,000 of interest to pay dissolution expenses), only as directed in the Termination
Letter and the other documents referred to therein, or (y) upon the date which is the later of (1) 24 months after the
closing of the Offering and (2) such later date as may be approved by the Company’s stockholders in accordance with
the Company’s certificate of incorporation (as amended), if a Termination Letter has not been received by the Trustee prior
to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination
Letter attached as Exhibit B and the Property in the Trust Account, including interest earned on the funds held in
the Trust Account and not previously released to the Company to pay its income taxes (less up to $100,000 of interest to pay dissolution
expenses), shall be distributed to the Public Stockholders of record as of such date. It is acknowledged and agreed that there
should be no reduction in the principal amount per share initially deposited in the Trust Account;

 

(j)            Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto
as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and
distribute to the Company the amount of interest earned on the Property requested by the Company to cover any 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 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 “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute
to the remitting brokers on behalf of Public Stockholders redeeming Common Stock the amount required to pay redeemed Common Stock
from Public Stockholders pursuant to the Company’s certificate of incorporation (as amended); and

 

    2

     

    

 

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

 

2.            Agreements
and Covenants of the Company. The Company hereby agrees and covenants to:

 

(a)            Give
all instructions to the Trustee hereunder in writing, signed by the Company’s Chief Executive Officer, Chief Financial Officer
or other authorized officer of the Company. In addition, except with respect to its duties under Sections 1(i), (j) or
(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(k) 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) and as may be provided in Section 2(b) hereof;

 

(d)            In
connection with any vote of the Company’s stockholders 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 stockholder meeting verifying the vote
of such stockholders 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;

 

(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

     

    

 

(h)            If
the Company seeks to amend any provisions of its certificate of incorporation (as amended) (A) to modify the substance or
timing of the Company’s obligation to provide holders of the Common Stock the right to have their shares redeemed in connection
with the Company’s initial Business Combination or to redeem 100% of the Common Stock if the Company does not complete its
initial Business Combination within the time period set forth therein or (B) with respect to any other provision relating
to the rights of holders of the Common Stock (in each case, an “Amendment”), the Company will provide
the Trustee with a letter (an “Amendment Notification Letter”) in the form of Exhibit D providing
instructions for the distribution of funds to Public Stockholders who exercise their redemption option in connection with such
Amendment; and

 

(i)            Within
five (5) business days after the Underwriter exercises its option to purchase additional units (or any unexercised portion
thereof) or such option to purchase additional units 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:

(c)            Institute
any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of

as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses incident
thereto;

 

(d)            Change

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;

 

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

 

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

 

(j)             File

    4

     

    

 

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

 

(l)             Verify
calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i),
1(j) or 1(k) hereof.

 

4.            Trust
Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”)
to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account
that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including,
without limitation, under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such
Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust
Account.

 

5.            Termination.
This Agreement shall terminate as follows:

 

(a)            If
the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such
time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to become
subject to the terms of this Agreement, the Trustee shall 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. In
executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including, account names,
account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank.
Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not
be liable for any loss, liability or expense resulting from any error in the information or transmission of the funds.

Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving

Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together
shall constitute but one instrument.

 

    5

     

    

 

(c)            This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except
for Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted
without the affirmative vote of sixty-five percent (65%) of the then outstanding 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 properly elected to redeem his or her Common Stock in connection with a stockholder vote to amend
this Agreement to modify the substance or timing of the Company’s obligation to provide for the redemption of the Common
Stock in connection with an initial Business Combination or an Amendment or to redeem 100% of its Common Stock if the Company does
not complete its initial Business Combination within the time frame specified in the Company’s certificate of incorporation
(as amended)), 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.

 

(d)            The
parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, State of New
York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS

		Re:	Trust Account Termination Letter

 

Dear Mr. Wolf and Ms. Gonzalez:

 

Pursuant to Section 1(i) of
the Investment Management Trust Agreement between One Equity Partners Open Water I Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (“Trustee”), dated as of January [●],
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 time period as you may agree) of the consummation of the Business Combination (the “Consummation
Date”). Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.

 

In accordance with the terms of the Trust
Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds
into the trust operating account at J.P. Morgan Chase Bank, N.A. to the effect that, on the Consummation Date, all of the funds
held in the Trust Account will be immediately available for transfer to the account or accounts that the Representatives (with
respect to the Deferred Discount) and the Company shall direct on the Consummation Date. It is acknowledged and agreed that while
the funds are on deposit in said trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company
nor the Representatives will earn any interest or dividends.

 

On the Consummation Date (i) counsel
for the Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated
substantially concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”),
and (ii) the Company shall deliver to you (a) a certificate by the Chief Executive Officer, Chief Financial Officer or
other authorized officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s
stockholders, if a vote is held and (b) 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 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.

 

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.
