	RE:	 Securities Subscription Agreement 

Ladies and Gentlemen: 
 Endeavor Acquisition
Corp., a Cayman Islands exempted company (the “Company”), is pleased to accept the offer Endeavor Sponsor LLC, a Cayman Islands limited liability company (the “Subscriber” or “you”), has made to
subscribe for 8,625,000 Class B ordinary shares of the Company (the “Shares”), $0.0001 par value per share (the “Class B Shares”), up to 1,125,000 of which are subject to surrender and
cancellation by you if the underwriters of the Company’s initial public offering (“IPO”) of units (“Units”) do not fully exercise their over-allotment option (the “Over-allotment Option”). For
the purposes of this Agreement, references to “Ordinary Shares” are to, collectively, the Class B Shares and the Company’s Class A ordinary shares, $0.0001 par value per share (the “Class A
Shares”). Pursuant to the Company’s memorandum and articles of association (the “Articles”), Class B Shares will convert into Class A shares on a one-for-one basis, subject to adjustment, upon the terms and conditions set forth in the Articles. Unless the context otherwise requires, as used herein “Shares” shall be deemed to include any
Class A Shares issued upon conversion of the Class B Shares comprising the Shares. The terms (this “Agreement”) on which the Company is willing to issue the Shares to the Subscriber, and the Company and the
Subscriber’s agreements regarding such Shares, are as follows: 
 1. Subscription for Shares. 

For the sum of $25,000 (the “Purchase Price”), which the Company acknowledges receiving in cash, the Company hereby issues
the Shares to the Subscriber, and the Subscriber hereby subscribes for and purchases the Shares from the Company, 1,125,000 of which are subject to surrender and cancellation, on the terms and subject to the conditions set forth in this Agreement.
Concurrently with the Subscriber’s execution of this Agreement, the Company shall update its Register of Members accordingly. All references in this Agreement to shares of the Company being surrendered and cancelled shall take effect as
surrenders and cancellations for no consideration of such shares as a matter of Cayman Islands law. Upon the issuance of the Shares, the Subscriber surrenders for no consideration the one Class B ordinary share of the Company currently held by
it following the incorporation of the Company. 

 2. Representations, Warranties and Agreements. 

2.1 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the
Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 2.1.1 No Government Recommendation or
Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Shares. 

2.1.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the
transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

2.1.3 Organization and Authority. The Subscriber is a Cayman Islands limited liability company, validly existing and in good standing
under the laws of the Cayman Islands and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement will be a legal, valid and binding
agreement of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of
creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

2.1.4 Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to
evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act (as
defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and
has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from
registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of Subscriber’s investment in the Shares. 

2.1.5 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had the
opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional
information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon
Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished
pursuant to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its prospects. 

 2.1.6 Regulation D Offering. Subscriber represents that it is an “accredited
investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made in reliance on a private placement
exemption to “accredited investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 

2.1.7 Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s own
account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not decide to enter into this Agreement as a result of any general solicitation or general
advertising within the meaning of Rule 502 under the Securities Act. 
 2.1.8 Restrictions on Transfer; Shell Company. Subscriber
understands the Shares are being offered in a transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” within the meaning of Rule 144(a)(3)
under the Securities Act and Subscriber understands that the certificates or book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise
transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. Subscriber agrees that if any transfer
of its Shares or any interest therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption,
the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation of the
initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 

2.1.9 No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 
 2.2 Company’s
Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1 Incorporation and Corporate Power. The Company is a Cayman Islands exempted company and is qualified to do business in every
jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority
necessary to carry out the transactions contemplated by this Agreement. 

 2.2.2 No Conflicts. The execution, delivery and performance of this Agreement and the
consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Articles, (ii) any agreement, indenture or instrument to which the Company is a party or (iii) any
law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject. 

2.2.3 Title to Shares. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Articles, and registration
on the register of members of the Company, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof the Subscriber will have or receive good title to the
Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and under the other agreements to which the Shares may be subject, (b) transfer restrictions under federal and state
securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 
 2.2.4 No Adverse
Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by
this Agreement or (ii) question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with any transactions. 

2.2.5 Authorization. The Class A Shares issuable upon conversion of the Class B Shares have been duly authorized and reserved
for issuance upon such conversion. 
 3. Surrender and Cancellation of Shares. 

3.1 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO
is not exercised in full, the Subscriber acknowledges and agrees that it (and, if applicable, any transferee of Shares) shall surrender for cancellation any and all rights to such number of Shares (up to an aggregate of 1,125,000 Shares and pro rata
based upon the percentage of the Over-allotment Option exercised) such that immediately following such surrender, the Subscriber (and any such transferees) will own an aggregate number of Shares (not including any private placement securities or
Class A Shares issuable upon exercise of any warrants or any securities purchased by Subscriber in the IPO or in the aftermarket) equal to 20% of the issued and outstanding Ordinary Shares immediately following the IPO. 

3.2 Termination of Rights as Shareholder. If any of the Shares are surrendered and cancelled in accordance with this Section 3,
then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such Shares, and the Company shall take such action as is appropriate to cancel such Shares. 

4. Waiver of Liquidation Distributions; Redemption Rights. 

In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim
of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public shareholders and into which substantially all of the proceeds of the IPO will be deposited (the
“Trust Account”), in the 

 
event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases securities
in the IPO or in the aftermarket, any Class A Shares so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to redeem any Ordinary Shares held by it into
funds held in the Trust Account upon the successful completion of an initial business combination. 
 5. Restrictions on Transfer.

 5.1 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly
known as an “Insider Letter”) dated on or prior to the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares
unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the Company has
received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and Exchange
Commission thereunder and with all applicable state securities laws. 
 5.2 Lock-up.
Subscriber acknowledges that the Shares will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter. Pursuant to the Insider
Letter, Subscriber will agree (subject to certain exceptions) not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares until the earlier to occur of: (A) one year after the completion of the
Company’s initial business combination or (B) the date on which the Company completes a liquidation, merger, stock exchange or other similar transaction after its initial business combination that results in all of its shareholders having
the right to exchange their Ordinary Shares for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, 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, the Shares will be released from the Lock-up. 

5.3 Restrictive Legends. All certificates representing the Shares shall have endorsed thereon legends substantially as follows: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS
AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH
ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.” 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.” 

 5.4 Additional Shares or Substituted Securities. In the event of the declaration of a
share capitalization, the declaration of an extraordinary dividend payable in a form other than Shares, a spin-off, a share sub-division, an adjustment in conversion
ratio, a recapitalization or a similar transaction affecting the Company’s outstanding Ordinary Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction
distributed with respect to any Shares subject to this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of
such securities or property shall be made to the number and/or class of Ordinary Shares subject to this Section 5 and Section 3. 

5.5 Registration Rights. Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the registration
requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a registration rights agreement to be entered into with the Company prior to the closing of the IPO (the
“Registration Rights Agreement”). 
 6. Other Agreements. 

6.1 Further Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 6.2 Notices. All notices, statements or other documents which are required or
contemplated by this Agreement shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
(ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to
such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day
following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 

6.3 Entire Agreement. This Agreement, together with that certain Insider Letter to be entered into between Subscriber and the Company
and the Registration Rights Agreement, each substantially in the form to be filed as an exhibit to the Registration Statement, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter
hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. 
 6.4 Modifications
and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto. 

6.5 Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted,
only by written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this
Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 

 6.6 Assignment. The rights and obligations under this Agreement may not be assigned
by either party hereto without the prior written consent of the other party. 
 6.7 Benefit. All statements, representations,
warranties, covenants and agreements in this Agreement shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to
create any rights or obligations except among the parties hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 

6.8 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and
governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. 

6.9 Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof,
contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full force and
effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor
any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by
a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or demand to any
other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 

6.11 Survival of Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in
any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any
claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any
such claim. 

 6.13 Headings and Captions. The headings and captions of the various subdivisions of
this Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
signature page were an original thereof. 
 6.15 Construction. The parties hereto have participated jointly in the negotiation and
drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any
party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.”
Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this
Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly
so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect,
the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that
such party hereto is in breach of the first representation, warranty, or covenant. 
 6.16 Mutual Drafting. This Agreement is the
joint product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

7. Voting and Tender of Shares. 

Subscriber agrees to vote the Shares in favor of an initial business combination that the Company negotiates and submits for approval to the
Company’s shareholders and shall not seek redemption or repurchase with respect to any of the Shares. Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the Company’s shareholders in
connection with an initial business combination negotiated by the Company. 
 8. Indemnification. 

Each party shall indemnify the other against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred as a
result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.

 Exhibit 10.6 

UNIT PURCHASE AGREEMENT 

This UNIT PURCHASE AGREEMENT (this “Agreement”) is made as of the [    ] day of
[        ] 2022, by and between Endeavor Acquisition Corp., a Cayman Islands exempted company (the “Company”), having its principal place of business
at 477 Madison Avenue, 6th Floor, New York, NY 10022, and Endeavor Sponsor LLC, a Cayman Islands limited liability company, having its principal place of business at 477 Madison Avenue, 6th Floor, New York, NY 10022 (the “Subscriber”). 
 WHEREAS, the Company
desires to sell on a private placement basis (the “Offering”) an aggregate of [ • ] units (“Units”) of the Company, each Unit comprised of one Class A ordinary share of the Company, par value
$0.0001 per share (“Ordinary Shares”), and one half of one warrant to purchase one Class A ordinary share (“Warrant”), for a purchase price of $[ • ], or $10.00 per Unit. The Ordinary Shares
underlying the Warrants are hereinafter referred to as the “Warrant Shares.” The Ordinary Shares underlying the Units (excluding the Warrant Shares) are hereinafter referred to as the “Placement Shares.” The
Warrants underlying the Units are hereinafter referred to as the “Placement Warrants.” The Units, Placement Shares, Placement Warrants and Warrant Shares, collectively, are hereinafter referred to as the
“Securities.” Placement Warrants may be exercised only to the extent that, when aggregated with other Placement Warrants being exercised, the exercise is for a whole share or whole shares; no fractional shares shall be issuable. The
exercise price for any Warrant Share shall be $11.50. Subject to the foregoing, the Placement Warrants are exercisable during the period commencing 30 days following the completion of the Company’s initial business combination (the
“Business Combination”), as such term is defined in the registration statement filed in connection with the IPO, as amended at the time it becomes effective (the “Registration Statement”), and expiring on the fifth
anniversary of the completion of the Business Combination; and WHEREAS, the Subscriber wishes to purchase the Units from the Company and the Company wishes to accept such subscription from the Subscriber. 

NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the Subscriber hereby agree as follows: 
  

	 	1.	 Agreement to Subscribe 

1.1 Purchase and Issuance of the Units. Upon the terms and subject to the conditions of this Agreement, the Subscriber hereby agrees to
purchase from the Company, and the Company hereby agrees to sell to the Subscriber, simultaneously with the closing of the IPO on or before [        ], 2022 (the
“Initial Closing Date”), [ • ] Units for a purchase price of $[ • ] (the “Purchase Price”). 

1.2 Delivery of the Purchase Price. Upon execution of this Agreement, the Company is bound to fulfill its obligations hereunder and the
Subscriber hereby irrevocably commits to deliver directly into a trust account (the “Trust Account” ) held at JP Morgan Chase Bank, N.A. or any other financial institution chosen by the Company, with Continental Stock
Transfer & Trust Company acting as trustee (“Continental”), the Purchase Price in immediately available funds by wire transfer or such other form of payment as shall be acceptable to Continental, in its sole and absolute
discretion, one (1) business day prior to the effective date of the Registration Statement. 
 1.3 Termination. This Agreement
and each of the obligations of the undersigned shall be null and void and without effect if the Closing does not occur prior to [        ], 2022. 

[Endeavor Acquisition Corp. Placement Unit Purchase Agreement] 

	 	2.	 Representations and Warranties of Subscriber 

The Subscriber represents and warrants to the Company that: 

2.1 No Government Recommendation or Approval. Subscriber understands that no federal or state agency has passed upon or made any
recommendation or endorsement of the Company or the Offering of the Securities. 
 2.2 Accredited Investor. Subscriber represents
that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being
made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law. 

2.3 Intent. Subscriber is purchasing the Securities solely for investment purposes, for such Subscriber’s own account (and/or for
the account or benefit of its members or affiliates, as permitted, pursuant to the terms of an agreement (the “Letter Agreement”) to be entered into with respect to the Securities between, among others, Subscriber and the Company,
as described in the Registration Statement), and not with a view to the distribution thereof and Subscriber has no present arrangement to sell the Securities to or through any person or entity except as may be permitted under the Letter Agreement.
Subscriber shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act. 
 2.4
Restrictions on Transfer. Subscriber acknowledges and understands the Units are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act. The Securities have not been
registered under the Securities Act and, if in the future Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an
effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available exemption from the
registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, Subscriber acknowledges and understands the Securities are
subject to transfer restrictions as described in Section 8 hereof. Subscriber agrees that, if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer Subscriber may be
required to deliver to the Company an opinion of counsel satisfactory to the Company with respect to such transfer. Absent registration or another available exemption from registration, Subscriber agrees it will not transfer the Securities (unless
otherwise permitted pursuant to the Letter Agreement, as described in the Registration Statement). Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to Subscriber for the resale of the
Securities until the one year anniversary following completion of the Business Combination, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 

2.5 Sophisticated Investor. 

(i) Subscriber’s managers and members are individually accredited investors and are sophisticated in financial matters and able to
evaluate the risks and benefits of the investment in the Securities. 

  
 2 

 (ii) Subscriber is aware that an investment in the Securities is highly speculative and
subject to substantial risks because, among other things, (a) the Securities are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the
Securities Act or an exemption from such registration is available and (b) Subscriber has waived its redemption rights with respect to the Securities as set forth in Section 5 hereof, and the Securities held by Subscriber are not entitled
to, and have no right, interest or claim to any monies held in the Trust Account, and accordingly Subscriber may suffer a loss of a portion or all of its investment in the Securities. Subscriber is able to bear the economic risk of its investment in
the Securities for an indefinite period of time. 
 2.6 Independent Investigation. Subscriber, in making the decision to purchase the
Units, has relied upon an independent investigation of the Company and has not relied upon any information or representations made by any third parties or upon any oral or written representations or assurances from the Company, its officers,
directors or employees or any other representatives or agents of the Company, other than as set forth in this Agreement. Subscriber is familiar with the business, operations and financial condition of the Company and has had an opportunity to ask
questions of, and receive answers from the Company’s officers and directors concerning the Company and the terms and conditions of the Offering and has had full access to such other information concerning the Company as Subscriber has
requested. Subscriber confirms that all documents that it has requested have been made available and that Subscriber has been supplied with all of the additional information concerning this investment which Subscriber has requested. 

2.7 Organization and Authority. Subscriber is duly organized, validly existing and in good standing under the laws of the Cayman
Islands and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. 
 2.8
Authority. This Agreement has been validly authorized, executed and delivered by Subscriber and is a valid and binding agreement enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy,
insolvency, fraudulent conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by equitable principles of general application and except as enforcement of
rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy.

	 	4.	 Legends 

4.1 Legend. The Company will issue the Units, Placement Shares and Placement Warrants, and, when issued, the Warrant Shares, purchased
by Subscriber in the name of Subscriber. The Securities will bear the following Legend and appropriate “stop transfer” instructions: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS AND NEITHER THESE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL FOR THIS CORPORATION, IS AVAILABLE.” 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER PURSUANT TO A LETTER AGREEMENT AMONG ENDEAVOR
ACQUISITION CORP. AND THE OTHER PARTIES THERETO AND MAY ONLY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF DURING THE TERM THEREOF PURSUANT TO THE TERMS SET FORTH IN THE LETTER AGREEMENT.” 

4.2 Subscriber’s Compliance. Nothing in this Section 4 shall affect in any way Subscriber’s obligations and agreements
to comply with all applicable securities laws upon resale of the Securities. 
 4.3 Company’s Refusal to Register Transfer of the
Securities. The Company shall refuse to register any transfer of the Securities if, in the sole judgment of the Company, such purported transfer would not be made (i) pursuant to an effective registration statement filed under the

	 	5.	 Waiver of Liquidation Distributions. 

In connection with the Securities purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or
claim of any kind in or to any distributions with respect to the Securities in connection with (i) the exercise of redemption rights in connection with the Company’s completion of the Business Combination, or (ii) upon the
Company’s redemption of Ordinary Shares upon the Company’s failure to complete the Business Combination within 18 months from the completion of the IPO or the liquidation of the Company prior to the expiration of such 18 month period. In
the event any Subscriber purchases Ordinary Shares in the IPO or in the aftermarket (“Public Shares”), Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions with respect to any
Public Shares in connection with the exercise of redemption rights in connection with the Company’s completion of the Business Combination. For the avoidance of doubt, Subscriber shall be eligible to redeem any Public Shares upon the same terms
offered to all other purchasers of Ordinary Shares in the IPO in the event the Company fails to complete the Business Combination, or liquidates, within 18 months from the completion of the IPO. 

 

	 	6.	 Termination of Placement Warrants. 

6.1 Failure to Complete Business Combination. The Placement Warrants shall be terminated upon the dissolution of the Company or in the
event that the Company does not complete the Business Combination within 18 months from the completion of the IPO. 
 6.2 Termination of
Rights as Holder. If the Placement Warrants are terminated in accordance with Section 6.1, then after such time, Subscriber (or its successor in interest) shall no longer have any rights as a holder of such Placement Warrants and the
Company shall take such action as is appropriate to cancel such Placement Warrants. The Subscriber hereby irrevocably grants the Company a limited power of attorney for the purpose of effectuating the foregoing and agrees to take any and all
measures reasonably requested by the Company necessary to effect the foregoing. 
  

	 	7.	 Rescission Right Waiver and Indemnification. 

7.1 The Subscriber understands and acknowledges an exemption from the registration requirements of the Securities Act requires there be no
general solicitation of purchasers of the Units. In this regard, if the IPO were deemed to be a general solicitation with respect to the Units, the offer and sale of such Units may not be exempt from registration and, if not, the Subscriber may have
a right to rescind its purchases of the Units. In order to facilitate the completion of the Offering and in order to protect the Company, its shareholders and the amounts in the Trust Account from claims that may adversely affect the Company or the
interests of its shareholders, Subscriber hereby agrees to waive, to the maximum extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek rescission of its purchase of the Units. The
Subscriber acknowledges and agrees this waiver is being made in order to induce the Company to sell the Units to Subscriber. The Subscriber agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes
of action, suits, claims or proceedings (collectively, “Claims”) and related losses, costs, penalties, fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including
reasonable attorneys’ and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against any Claims, whether pending or threatened, in connection with any present or future
actual or asserted right to rescind the purchase of the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby. 

7.2 The Subscriber agrees not to seek recourse against the Trust Account for any reason whatsoever in connection with its purchase of the
Units or any Claim that may arise now or in the future. 
 7.3 The Subscriber acknowledges and agrees that the shareholders of the Company
are and shall be third-party beneficiaries of this Section 7. 

  
 6 

 7.4 The Subscriber agrees that, to the extent any waiver of rights under this Section 7
is ineffective as a matter of law, Subscriber has offered such waiver for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies to a legal right. The Subscriber acknowledges the
receipt and sufficiency of consideration received from the Company hereunder in this regard. 
  

	 	8.	 Terms of the Units and Placement Warrant 

The Units and their component parts are substantially identical to the units to be offered in the IPO except that: (i) the Units and their
component parts will be subject to transfer restrictions, except in limited circumstances, until 30 days following the completion of the Business Combination, (ii) the Units and their component parts are being purchased pursuant to an exemption
from the registration requirements of the Securities Act and will become freely tradable only after they are registered or an exemption from registration is available, and the restrictions described above in clause (i) have expired. 

 

	 	9.	 Governing Law; Jurisdiction; Waiver of Jury Trial 

This Agreement shall be governed by and construed in accordance with the laws of the State of New York for agreements made and to be wholly
performed within such state. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby. 

 

	 	10.	 Assignment; Entire Agreement; Amendment 

10.1 Assignment. Neither this Agreement nor any rights hereunder may be assigned by any party to any other person other than by a
Subscriber to a person agreeing to be bound by the terms hereof, including the waiver contained in Section 7 hereof. 
 10.2 Entire
Agreement. This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of any and every nature among them.

 10.3 Amendment. Except as expressly provided in this Agreement, neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated other than by a written instrument signed by the party against whom enforcement of any such amendment, waiver, discharge or termination is sought. 

10.4 Binding upon Successors. This Agreement shall be binding upon and inure to the benefit of the parties hereto and to their
respective heirs, legal representatives, successors and permitted assigns. 
  

	 	11.	 Notices 

11.1 Notices. Unless otherwise provided herein, any notice or other communication to a party hereunder shall be sufficiently given if in
writing and personally delivered or sent by facsimile or other electronic transmission with copy sent in another manner herein provided or sent by courier (which for all purposes of this Agreement shall include Federal Express or other recognized
overnight courier) or mailed to said party by certified mail, return receipt requested, at its address provided for herein or such other address as either may designate for itself in such notice to the other. Communications shall be deemed to have
been received when delivered personally, on the scheduled arrival date when sent by next day or 2nd-day courier service, or if sent by facsimile upon receipt of confirmation of transmittal or, if sent by mail,
then three days after deposit in the mail. If given by 

  
 7 

 
electronic transmission, such notice shall be deemed to be delivered (a) if by electronic mail, when directed to an electronic mail address at which the recipient has consented to receive
notice; (b) if by a posting on an electronic network together with separate notice to the recipient of such specific posting, upon the later of (1) such posting and (2) the giving of such separate notice; and (c) if by any other
form of electronic transmission, when directed to the recipient. 
  

	 	12.	 Counterparts 

This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and
shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile
transmission or by e-mail delivery of a “pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with
the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 
  

	 	13.	 Survival; Severability 

13.1 Survival. The representations, warranties, covenants and agreements of the parties hereto shall survive the Closing. 

13.2 Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that no such severability shall be effective if it materially changes the economic benefit of this Agreement to any party. 

 

	 	14.	 Headings. 

The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this
Agreement.
