	RE:	 Securities Subscription Agreement 

Gentlemen: 
 This agreement (this
“Agreement”) is entered into on December 16, 2020 by and between Arctos NorthStar Acquisition Holdings, LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Arctos
NorthStar Acquisition Corp., a Cayman Islands exempted company (the “Company”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to subscribe for and purchase 7,906,250 Class B ordinary
shares, $0.0001 par value per share (the “Shares”), up to 1,031,250 of which are subject to surrender and cancellation by you if the underwriters of the initial public offering (“IPO”) of units
(“Units”) of the Company do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows: 

1. Purchase of Securities. 
 1.1
Purchase of 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, 1,031,250 of which are subject to surrender and cancellation, on the terms and subject to the conditions set forth in this Agreement. All references in this Agreement to shares of the Company being surrendered
and canceled shall take effect as surrenders and cancellations for no consideration of such shares as a matter of Cayman Islands law. 
 1.2
Surrender of Subscriber Share. On the issuance of the Shares, the Subscriber hereby surrenders for no consideration the one Class B ordinary share, $0.0001 par value that the Subscriber holds in 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 Registration and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good standing under
the laws of the State of Delaware 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 of
1933, as amended (the “Securities Act”) 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: (x) an effective registration statement under the
Securities Act or (y) 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 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 federal and 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 of Regulation D 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
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 or necessary on the part of Subscriber in connection with the transactions contemplated by this Agreement. 

  
 2 

 2.2 Company’s Representations, Warranties and Agreements. To induce the
Subscriber to subscribe for and 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. Upon execution and delivery by the Company, this Agreement will be a legal, valid and binding agreement of the Company, enforceable against the Company 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). 
 2.2.2 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 memorandum and articles of association of the Company, (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 Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and registration in the
Company’s register of members, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and registration in the Company’s register of members,
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 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. 
 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 representative(s) of the
underwriters of the Company’s IPO is not exercised in full, the Subscriber acknowledges and agrees that it shall surrender for cancellation any and all rights to such number of Shares (up to an aggregate of 1,031,250 Shares and pro rata based
upon the percentage of the Over-allotment Option exercised) such that immediately following such surrender, the Subscriber (and all other initial shareholders prior to the IPO, if any) will own an aggregate number of Shares (not including ordinary
shares issuable upon exercise of any warrants or any ordinary shares subscribed for and purchased by Subscriber in the Company’s IPO or in the aftermarket) equal to 20% of the issued and outstanding ordinary shares of the Company 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 subscribed for and 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 subscribes for and purchases ordinary shares in the IPO or in the aftermarket, any additional Shares so subscribed for and 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 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”) to be dated as of 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 Restrictive Legends. Any 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 LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.” 

5.3 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 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 Shares subject to this Section 5 and Section 3. 
 5.4 Registration Rights. Subscriber acknowledges
that the Shares are being subscribed for and 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 and Shareholder Rights Agreement to be entered into with the Company at or prior to the closing of the IPO. 
 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,

 6.3 Entire Agreement. This Agreement, together with that certain Insider Letter to be
entered into between Subscriber and the Company, substantially in the form to be filed as an exhibit to the Registration Statement on Form S-1 associated with the Company’s IPO, 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. No statement, representation,
warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 

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 a 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 Delaware 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. 

  
 5 

 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 such 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.

one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one-third of one redeemable warrant (each whole warrant, a

an aggregate purchase price of $7,500,000 (or up to $8,325,000 if the Underwriter’s exercise their option to purchase additional units), or $1.50 per Warrant, in a private placement that shall close simultaneously with the consummation of the
Public Offering (including Ordinary Shares issuable upon conversion thereof); (iv) “Public Shareholders” shall mean the holders of Ordinary Shares included in the Units issued in the Public Offering; (v) “Public
Shares” shall mean the Ordinary Shares included in the Units issued in the Public Offering; (vi) “Trust Account” shall mean the trust account into which a portion of the net proceeds of the Public Offering and

dispose of or agreement to dispose of, directly or indirectly, or

(b); and (viii) “Charter” shall mean the Company’s Second Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time. 

2. Representations and Warranties. 

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

(b) Each Insider represents and warrants, with respect to herself or himself, that such Insider’s biographical information furnished to
the Company (including any such information included in the Prospectus) is true and accurate in all material respects and does not omit any material information with respect to such Insider’s background. The Insider’s questionnaire
furnished to the Company is true and accurate in all material respects. Each Insider represents and warrants that such Insider is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; such Insider has never been convicted of, or pleaded

(ii) as promptly as reasonably possible but not more than 10 business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on
deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of
then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably
possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman
Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The Sponsor and each Insider agree not to propose any amendment to the Charter (i) that would modify the substance or timing of
the Company’s obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete an initial
Business Combination within the required time period set forth in the Charter or (ii) with respect to any provision relating to the rights of holders of Public Shares or pre-initial Business Combination
activity unless the Company provides its Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate
amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, if any, divided by the number of then-outstanding Public Shares. 

(b) The Sponsor and each Insider, with respect to itself, herself or himself, acknowledges that it, she or he has no right, title, interest or
claim of any kind in or to any monies held in the Trust Account 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, her or him, if any. The Sponsor and each of the Insiders
hereby further waive, with respect to any Founder Shares and Public Shares held by it, her or him, as applicable, any redemption rights it, she or he may have in connection with the consummation of a Business Combination, including, without
limitation, any such rights available in the context of a shareholder vote to approve such Business Combination or a shareholder vote to approve an amendment to the Charter (i) that would modify the substance or timing of the Company’s
obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination
within the time period set forth in the Charter or (ii) with respect to any provision relating to the rights of holders of Public Shares (although the Sponsor and the Insiders shall be entitled to liquidation rights with respect to any Public
Shares they hold if the Company fails to consummate a Business Combination within the required time period set forth in the Charter).

 5. Lock-up; Transfer Restrictions. 

(a) The Sponsor and the Insiders agree that they shall not Transfer any Founder Shares (the “Founder Shares Lock-up”) until the earlier of (A) one year after the completion of an initial Business Combination and (B) the date following the completion of an initial Business Combination on which the
Company completes a liquidation, merger, share exchange 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”). Notwithstanding the foregoing, if, subsequent to a Business Combination, the closing price of the Ordinary Shares equals or exceeds $12.00 per share
(as adjusted for share sub-divisions, share capitalizations, share consolidations, reorganizations, recapitalizations and other similar transactions) for any 20 trading days within a 30-trading day period commencing at least 150 days after the Company’s initial Business Combination, the Founder Shares shall be released from the Founder Shares Lock-up.

 (b) The Sponsor and Insiders agree that they shall not effectuate any Transfer of Private Placement Warrants or Ordinary Shares
underlying such warrants until 30 days after the completion of an initial Business Combination. 
 (c) Notwithstanding the provisions set
forth in paragraphs 5(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and Ordinary Shares underlying the Private Placement Warrants 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 members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (b) in the case of an
individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in
the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection
with any forward purchase agreement or similar arrangement or in connection with the consummation of a Business Combination at prices no greater than the price at which the Founder Shares, Private Placement Warrants or Ordinary Shares, as
applicable, were originally purchased; (f) by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (g) to the Company for no value for cancellation in connection with the consummation of an
initial Business Combination; (h) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (i) in the event of completion of a liquidation, merger, share exchange or other similar transaction
which results in all of the Company’s Public Shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of an initial Business Combination; provided,
however, that in the case of clauses (a) through (f) these permitted transferees must enter into a written agreement agreeing to be bound by the transfer restrictions set forth in this Agreement. 

(d) During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each
Insider shall not, without the prior written consent of the Underwriter, Transfer any Units, Ordinary Shares, Warrants or any other securities convertible into, or exercisable or exchangeable for, Ordinary Shares held by it, her or him, as
applicable, subject to certain exceptions enumerated in Section 6(g) of the Underwriting Agreement.

 6. Remedies. The Sponsor and each of the Insiders hereby agree and acknowledge that
(i) each of the Underwriter and the Company would be irreparably injured in the event of a breach by the Sponsor or such Insider of its, her or his obligations, as applicable under paragraphs 3, 4, 5,
7, 10 and 11, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other
remedy that such party may have in law or in equity, in the event of such breach. 
 7. Payments by the Company. Except as disclosed
in the Prospectus, neither the Sponsor nor any affiliate of the Sponsor nor any director or officer of the Company nor any affiliate of the officers shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in
respect of any payment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it
is). 
 8. Director and Officer Liability Insurance. The Company will maintain an insurance policy or policies providing
directors’ and officers’ liability insurance, and the Insiders shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available for any of the Company’s directors or
officers. 
 9. Termination. This Letter Agreement shall terminate on the earlier of (i) the expiration of the Founder Shares Lock-up Period and (ii) the liquidation of the Company. 
 10. Indemnification. In the event
of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”) agrees to indemnify and
hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any
litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company (except for the Company’s independent auditors) or
(ii) any prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”); provided, however, that such indemnification of the Company by the Indemnitor
(x) shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00
per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due to reductions in the value of the trust assets, in each case
net of interest that may be withdrawn to pay the Company’s tax obligations, (y) shall not apply to any claims by a third party or Target who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not
such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Indemnitor shall have
the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that
it shall undertake such defense.

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

13. Assignment. No party hereto may assign either this Letter Agreement or any of its rights, interests or obligations hereunder
without the prior written consent of the other parties. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter
Agreement shall be binding on the Sponsor, each of the Insiders and each of their respective successors, heirs, personal representatives and assigns and permitted transferees. 

14. Counterparts. This Letter Agreement may be executed in any number of original , electronic 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.
