 Re: Initial Public Offering

 Ladies and Gentlemen: 
 This letter (this
“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and among Endeavor Acquisition Corp., a Cayman Islands
exempted company (the “Company”), and Cantor Fitzgerald & Co. and Mizuho Securities USA LLC, as representatives (the “Representatives”) of the several underwriters (each, an
“Underwriter” and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 25,875,000 of the Company’s units
(including up to 3,375,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one Class A ordinary share of the Company, par value
$0.0001 per share (the “Ordinary Shares”), and one-half of one warrant. Each whole Warrant (each, a “Warrant”) entitles the holder thereof to purchase one
Ordinary Share. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 (File
No. 333-[ ⚫ ]) and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the
“Commission”) and the Company shall apply to have the Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in Section 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, Endeavor 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, hereby agree with the Company as follows: 
 1. The Sponsor and each Insider agrees that (A) if
the Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote any Shares owned by it, him or her in favor of any proposed Business Combination
and (ii) not redeem any Shares owned by it, him or her in connection with such shareholder approval, (B) if the Company engages in a tender offer in connection with any proposed Business Combination, it, he or she shall not sell any Shares
to the Company in connection therewith and (C) if the Company seeks shareholder approval of any proposed amendment to the Charter prior to the completion of a Business Combination, it, he or she shall not redeem any Shares owned by it, him or
her in connection with such shareholder approval. 
 2. The Sponsor and each Insider hereby agrees that in the event that the Company fails
to complete a 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, subject to lawfully available funds therefor, redeem 100% of the Ordinary Shares sold as part of the Units in the Public Offering (the “Offering
Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not
previously released to the Company to pay any taxes (less up to $100,000 of interest to pay winding up and dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public
Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of
the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to the Company’s obligations under Cayman Islands law to provide for claims of
creditors and other requirements of applicable law. The Sponsor and each Insider agrees to not propose any amendment to the Charter (i) that would affect the substance or timing of the Company’s obligation to provide holders of the
Offering Shares the right to have their Offering Shares redeemed in connection with the Business Combination or redeem 

  
 1 

 
100% of the Offering Shares if the Company does not complete a Business Combination within the time period described in the Prospectus or (ii) with respect to any other provision relating to
shareholders’ rights or pre-Business Combination activity, unless the Company provides its public shareholders with the opportunity to redeem their Ordinary 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 any taxes, divided by the number of then outstanding Offering Shares. 
 The Sponsor and each Insider acknowledges that it, he or she
has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, him or her. The Sponsor
and each Insider hereby further waives any claim such Sponsor or Insider may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Fund for any reason
whatsoever except in each case with respect to the Sponsor’s or the Insider’s right to a pro rata interest in the proceeds held in the Trust Fund for any Offering Shares such Sponsor or Insider may hold. 

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, and the rules and regulations of the
Commission promulgated thereunder, with respect to any Units, Ordinary Shares, Founder Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, (ii) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units, Ordinary Shares, Founder Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for,
Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or
(ii). Each of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver of the restrictions set forth in this Section 3, the Company shall announce the impending release or waiver by press
release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of such press release. The
provisions of this Section will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the
extent and for the duration that such terms remain in effect at the time of the transfer. 
 4. In the event of the liquidation of the Trust
Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and
expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company
may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or
other similar agreement or a Business Combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that such
claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.20 per share of the Offering Shares or (ii) such lesser amount per share of the
Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be
withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters
against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of
any liability for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company. 

  
 2 

 5. To the extent that the Underwriters do not exercise their
over-allotment option to purchase up to an additional 3,375,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to surrender, at no cost, a
number of Founder Shares in the aggregate equal to 843,750 multiplied by a fraction, (i) the numerator of which is 3,375,000 minus the number of Units purchased by the Underwriters upon the exercise of their
over-allotment option, and (ii) the denominator of which is 3,375,000. 
 6. The Sponsor and
each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under Sections 1, 2, 3, 4, 5, 7(a),
7(b), and 9, as applicable, of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in
addition to any other remedy that such party may have in law or in equity, in the event of such breach. 
 7. (a) Subject to
Section 7(c), the Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or Ordinary Shares issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s
initial Business Combination or (B) subsequent to the Business Combination, (x) if the last sale price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, rights issuances,
subdivisions, 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, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash,
securities or other property (the “Founder Shares Lock-up Period”). 

(b) Subject to Section 7(c), the Sponsor and each Insider agrees that it, he or she shall not Transfer any Placement Units, Sponsor Loan
Units, Placement Shares, Sponsor Loan Shares, Placement Warrants (or Ordinary Shares issued or issuable upon the conversion or exercise of Placement Warrants), Sponsor Loan Warrants (or Ordinary Shares issued or issuable upon the conversion or
exercise of Sponsor Placement Warrants) until 30 days after the completion of a Business Combination (the “Placement Unit Lock-up Period”, together with the Founder Shares
Lock-up Period, the “Lock-up Periods”). 

(c) Notwithstanding the provisions set forth in Sections 7(a) and (b), Transfers of the Founder Shares, Placement Units, Sponsor Loan
Units, Placement Shares, Placement Warrants, Sponsor Loan Warrants and Ordinary Shares issued or issuable upon the exercise or conversion of Placement Warrants or Sponsor Loan Warrants or the Founder Shares and that are held by the Sponsor, any
Insider or any of their permitted transferees (that have complied with this Section 7(c)), are permitted (1) (a) to the Company’s officers and directors, the Initial Holders, and other Insiders, (b) to an affiliate or immediate family
member of any of the Company’s officers, directors, Initial Holders and other Insiders, (c) to any member, officer or director of the Sponsor, or any immediate family member, partner, affiliate or employee of a member of the Sponsor,
(d) by gift to any permitted transferee under any of the immediately preceding subsections (a) through (c), a trust, the beneficiaries of which are one or more permitted transferees under any of the immediately preceding
subsections (a) through (c), or a charitable organization, (e) by virtue of laws of descent and distribution upon death of any of the Company’s officers, directors, Initial Holders or members of the Sponsor, (f) pursuant to a
qualified domestic relations order, (g) in the event of the Company’s liquidation prior to completion of the initial Business Combination, (h) by virtue of the laws of the Cayman Islands or the Sponsors’ limited liability company
agreements upon dissolution of either Sponsor, (i) subsequent to the initial Business Combination, upon and in connection with a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s
shareholders having the right to exchange their Ordinary Shares for cash, securities or other property, (j) subsequent to the initial Business Combination, in the event of a consolidation merger, share exchange or similar transaction in which
the Company is the surviving entity that results in a change in the majority of its board of directors or management team and (k) through private sales or transfers made in connection with any forward purchase agreement or similar arrangement
or in connection with the completion of the initial Business Combination at prices no greater than the price at which the Founder Shares, Placement Shares, Sponsor Loan Shares or Warrants were originally purchased; provided, however, that in the
case of clauses (a) through (f), (h) and (k) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions, and (2) in connection with an initial Business Combination with the
consent of the Company to any third party that agrees in writing to be bound by the provisions of this Letter Agreement applicable to Insiders (other than paragraph 1). For the avoidance of doubt, for the purposes of this Letter Agreement, a managed

such writ in whole or in part in any order desired by Payee. 
 8. Unconditional Liability. Maker hereby waives all notices in

	 Principal Amount: $300,000
	  	Dated as of January 13, 2022

 Endeavor Acquisition Corp., a Cayman Islands exempted company (the
“Maker”), promises to pay to the order of Endeavor Sponsor LLC, a Cayman Islands limited liability company, or its registered assigns or successors in interest (the “Payee”), or order, the principal
sum of Three Hundred Thousand Dollars ($300,000) or such lesser amount as shall have been advanced by Payee to Maker and shall remain unpaid under this Note on the Maturity Date (as defined below) in lawful money of the United States of America, on
the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by
written notice in accordance with the provisions of this Note. 
 The Maker and Payee entered into a Promissory Note for the principal sum
of Three Hundred Thousand Dollars ($300,000) on June 15, 2021 (the “Prior Note”) and, by entering into this Note, wish to amend and restate the Prior Note in its entirety in order to, among other items, extend the Maturity Date, as defined
below. Upon the effectiveness of this Note, the Prior Note shall be deemed amended and restated and superseded and replaced in its entirety by this Note, and shall be of no further force or effect. 

1. Principal. The entire unpaid principal balance of this Note shall be payable by the Maker on the earlier of: (i) June 30,
2022, or (ii) the date on which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). The principal balance may be prepaid at any time. Under no circumstances shall any
individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder. 

2. Drawdown Requests. Maker and Payee agree that Maker may request, from time to time, up to Three Hundred Thousand Dollars ($300,000)
in draw downs under this Note to be used for costs and expenses related to Maker’s formation and the proposed initial public offering of its securities (the “IPO”). Principal of this Note may be drawn down from time to
time prior to the Maturity Date upon written request from Maker to Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must not be an amount less than Ten Thousand Dollars
($10,000). Payee shall fund each Drawdown Request no later than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns outstanding under this Note at any time may not exceed Three
Hundred Thousand Dollars ($300,000). No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker. 

 3. Interest. No interest shall accrue on the unpaid principal balance of this Note.

 4. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any
sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note. 

5. Events of Default. The following shall constitute an event of default (“Event of Default”): 

(a) Failure to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note within five
(5) business days of the date specified above. 
 (b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case
under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar
official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by
Maker in furtherance of any of the foregoing. 
 (c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a
court having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar

60 consecutive days. 
 6. Remedies. 

(a) Upon the occurrence of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to Maker, declare this Note
to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable thereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding. 
 (b) Upon
the occurrence of an Event of Default specified in Sections 5(b) or 5(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases
without any action on the part of Payee.

accrue to Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of
execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any
such writ in whole or in part in any order desired by Payee. 
 8. Unconditional Liability. Maker hereby waives all notices in
connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any
manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payee with respect to the
payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker’s liability hereunder.

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 12. Trust Waiver. Notwithstanding anything herein to
the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution of or from the trust account to be established in which the proceeds of the IPO conducted by the Maker
(including the deferred underwriters discounts and commissions) and the proceeds of the sale of the units issued in a private placement to occur prior to the consummation of the IPO are to be deposited, as described in greater detail in the
