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 Integral Acquisition Corporation 1, a Delaware corporation (the “Company”), and Wells Fargo Securities, LLC, as representative
(the “Representative”) of the underwriters (each, an “Underwriter” and collectively, the “Underwriters”), relating to an underwritten initial public offering (the
“Public Offering”), of up to 11,500,000 of the Company’s units (including up to 1,500,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one
share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), and one half of one redeemable warrant. Each whole warrant (each, a
“Warrant”) entitles the holder thereof to purchase one share of Class A Common Stock 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 Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 11 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 Integral Sponsor LLC (the “Sponsor”) and the undersigned individuals, each of whom is 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 agree that if the Company seeks stockholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, it, he or she shall (i) vote any shares of Common Stock (as defined below) owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned
by it, him or her in connection with such stockholder approval. If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider agree that it, he or she will not sell or tender any
shares of Common Stock owned by it, him or her in connection therewith. 
 2. The Sponsor and each Insider hereby agree that in the event
that the Company fails to consummate a Business Combination within 18 months after the closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated
certificate of incorporation (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 business days thereafter, redeem 100% of the shares of Class A Common Stock sold as part of the Units in the Public Offering (the “Offering
Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the
Trust Account (which interest shall be net of taxes payable and less 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
Stockholders’ (as defined below) rights as stockholders (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 stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of
applicable law. The Sponsor and each Insider agree to not propose any amendment to the Charter to modify the substance or timing of the Company’s obligation to redeem 100% of the 

 
Offering Shares if the Company does not complete a Business Combination within the required time period set forth in the Charter or with respect to any other material provisions relating to
stockholders’ rights or pre-initial business combination activity, unless the Company provides its Public Stockholders with the opportunity to redeem their Offering Shares upon approval of any such
amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest 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 acknowledge 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 waive, with respect to any shares of Common Stock held by it, him or her, if any, any redemption rights it, he or she may have in connection with (A) 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 (B) a stockholder vote to approve an amendment to the Charter to modify the substance or timing of the
Company’s obligation 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 with respect to any other material provisions relating to stockholders’
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. 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, shares of Common Stock (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or
exercisable or exchangeable for, shares of Common Stock 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, shares of
Common Stock (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable or exchangeable for, shares of Common Stock 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). 

4. 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) $10.10 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 $10.10 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 that 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. 

 5. To the extent that the Underwriters do not exercise their over-allotment option to
purchase up to an additional 1,500,000 Units within 45 days after the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal to 375,000
multiplied by a fraction, (i) the numerator of which is 1,500,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000. 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 20.0% of the Company’s issued and outstanding shares of Class A Common Stock
after the Public Offering (not including shares of Class A Common Stock underlying the Warrants or Private Placement Warrants (as defined below)). The Sponsor further agrees 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 20.0% of its issued and outstanding shares of Class A Common Stock upon the consummation of the Public Offering (not including shares of Class A Common Stock underlying the Warrants or Private
Placement Warrants). In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,500,000 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 Public Shares included in the Units issued in the Public Offering and (B) the reference to 375,000 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of
Founder Shares that the Sponsor would have to surrender to the Company in order for the initial shareholders to hold an aggregate of 20.0% of the Company’s issued and outstanding shares of Class A Common Stock after the Public Offering
(not including shares of Class A Common Stock underlying the Warrants or Private Placement Warrants). 
 6. The Sponsor and each
Insider hereby agree and acknowledge that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), and 7(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. 
 7. (a) The Sponsor and each Insider agree
that it, he or she shall not Transfer any Founder Shares (or any shares of Class A Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination and
(B) subsequent to the Business Combination, (x) if the closing price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for
any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date on which the Company completes a liquidation,
merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property (the
“Founder Shares Lock-up Period”). 
 (b) The Sponsor and each Insider
agree that it, he or she shall not Transfer any Private Placement Warrants (or any share of Class A Common Stock issued or issuable upon the exercise of the Private Placement Warrants), until 30 days after the completion of a Business
Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”). 
 (c) Notwithstanding the provisions set forth in paragraphs 7(a)
and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of Class A Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares that are held by the Sponsor, any
Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any 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 State of Delaware 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 that results in all of the Company’s stockholders having the right to
exchange their shares of Class A Common Stock 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). 
 8. 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. 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 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. 
 9. 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 $300,000 made to the Company by the Sponsor; payments to the Sponsor
for certain office space, secretarial and administrative services as may be reasonably required by the Company of $20,000 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 $1.00 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. 
 10. The 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. 

11. 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) “Common Stock” shall mean the Class A common stock and Class B common stock; (iii) “Founder

Underwriters); (iv) “Initial Stockholders” shall mean the Sponsor and any Insider that holds Founder Shares; (v) “Private Placement Warrants” shall mean the 4,860,000 Warrants (or, if the
underwriters’ over-allotment option is exercised, up to 4,935,000 Warrants) that the Sponsor has agreed to purchase for an aggregate purchase price of $4,860,000 (or, if the underwriters’ over-allotment option is exercised up to
$4,935,000), or $1.00 per Warrant, in a private placement that shall occur simultaneously with the consummation of the Public Offering; (vi) “Public Stockholders” 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; (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 any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security,

any of the Company’s directors or officers. 
 13. 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. 

14. 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. 
 15. Nothing in this
Letter Agreement shall be construed to confer upon, or give to, any person or corporation other than the parties hereto any right, remedy or claim under or by reason of this Letter Agreement or of any covenant, condition, stipulation, promise or

and permitted transferees. 
 16. 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. 

17. 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. 

18. This Letter Agreement and all matters arising therefrom or relating thereto 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. 
 19. 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. 

 20. 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 terminate in the event that the Public Offering is not consummated and closed by
December 31, 2021; provided further that paragraph 4 of this Letter Agreement shall survive such liquidation.

 Exhibit 10.2 

FORM OF INVESTMENT MANAGEMENT TRUST AGREEMENT 

This Investment Management Trust Agreement (this “Agreement”) is made effective as of [•], 2021 by and between
Integral Acquisition Corporation 1, 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. 333-257058 (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 share of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), and one-half 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 Wells Fargo
Securities, LLC, as representative (the “Representative”) of the underwriters (the “Underwriters”) named therein; and 

WHEREAS, as described in the Prospectus, $101,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as
defined in the Underwriting Agreement) (or $116,150,000 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 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”); 
 WHEREAS,
pursuant to the Underwriting Agreement, a portion of the Property equal to $4,000,000, or $4,900,000 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) in the United States, maintained by the Trustee and at a brokerage institution selected
by the Trustee that is reasonably satisfactory to the Company; 
 (b) Manage, supervise and administer the Trust Account subject to the
terms and conditions set forth herein; 
 (c) In a timely manner, upon the written instruction of the Company, invest and reinvest the
Property 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 Representative
of all communications received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply any necessary
information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account; 

(g) Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when
instructed by the Company to do so; 
 (h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust
Account reflecting all receipts and disbursements of the Trust Account; 
 (i) Commence liquidation of the Trust Account only after and
promptly 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 Representative, and complete the liquidation of the Trust Account and distribute the Property in the
Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its 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) 18 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 Amended and Restated Certificate of Incorporation 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 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; 
 (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 “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public
Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to provide the
redemption of the shares of Common Stock included in the Units sold in the Offering (the ‘“public shares”) in connection with the initial Business Combination or to redeem 100% of 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 Certificate of Incorporation or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business Combination activity. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have
no responsibility to look beyond said request; and 
 (l) Not make any withdrawals or distributions from the Trust Account other than
pursuant to 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

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 stockholders regarding a merger, capital stock exchange, asset acquisition, stock
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 Representative
with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same; 

(f) Unless otherwise agreed between the Company and the Representative, ensure that any Instruction Letter (as defined in Exhibit A)
delivered in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid directly to the account or accounts directed by the Representative on behalf of the Underwriters prior to any
transfer of the funds held in the Trust Account to the Company or any other person; 
 (g) Instruct the Trustee to make only those
distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement; 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 is as
contemplated by the Registration Statement; 
 (i) File information returns with respect to the Trust Account with any local, state or
federal taxing authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

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

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

 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 after 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. 
 (b) This Agreement, and all matters arising therefrom or relating thereto, shall be governed by and construed
and enforced in accordance with the laws of the State of New York. This 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. 

(c) This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Subject to
Section 6(d) hereof, 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) This Agreement or any provision hereof may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent of
the Stockholders. For purposes of this Section 6(d), the “Consent of the Stockholders” means receipt by the Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s
stockholders of record as of a record date established in accordance with Section 213(a) of the Delaware General Corporation Law, as amended (“DGCL”) (or any successor rule), who hold sixty-five percent (65%) or more of all then
outstanding shares of the Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single class, have voted in favor of such change, amendment or modification. No such amendment will affect any
Public Stockholder who has otherwise indicated his election to redeem his shares of Common Stock in connection with a stockholder vote sought to amend this Agreement to modify the substance or timing of the Company’s obligation to redeem 100%
of the Common Stock if the Company does not complete its initial Business Combination within the time frame specified in the Company’s Amended and Restated Certificate of Incorporation. Except for any liability arising out of the Trustee’s
gross negligence, fraud or willful misconduct, the Trustee may rely conclusively on the certification from the inspector or elections referenced above and shall be relieved of all liability to any party for executing the proposed amendment in
reliance thereon. 

 (e) 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 AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY. 

(f) Any notice, consent or request to be given in connection with any of the terms or provisions of this 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 by electronic mail:

Re: Trust Account – Termination Letter 

Dear Mr./Ms. [•]: 
 Pursuant to
Section 1(i) of the Investment Management Trust Agreement between Integral Acquisition Corporation 1 (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 Operating
Account at JPMorgan Chase Bank, N.A. 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 Representative 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 by the Chairman, 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 stockholders, if a vote is held and (b) a joint written instruction signed by the Company and the Representative with respect to the transfer of the funds held in the Trust Account, including payment of amounts
owed to public stockholders who have properly exercised their redemption rights and payment of the Deferred Discount directly to the account or accounts directed by the Representative 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.
