unincorporated organization, association, joint venture or any other organization or entity, whether or not a legal entity (each an “Indemnified Person”) to the fullest extent permitted under the Act, as the same now exists or may
hereafter be amended, substituted or replaced (but, in the case of any such amendment, substitution or replacement only to the extent that such amendment, substitution or replacement permits the Company to provide broader indemnification rights than
the Company is providing immediately prior to such amendment), against all expenses, liabilities and losses (including attorneys’ fees, judgments, fines, excise taxes or penalties) reasonably incurred or suffered by such Indemnified Person (or
one or more of such Indemnified Person’s affiliates) by reason of the fact that such Indemnified Person is or was a Member or is or was serving at the request of the Company as the Managing Member, an officer, an employee or another agent of
the Company or is or was serving at the request of the Company as a manager, member, employee or agent of another limited-liability company, corporation, partnership, joint venture, trust or other enterprise; provided, however, that no
Indemnified Person shall be indemnified for actions not made in good faith and not or in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company, or, with respect to any criminal action or proceeding
other than by or in the right of the Company, had reasonable cause to believe the conduct was 

  
 5 

 
unlawful, or for any present or future breaches of any representations, warranties or covenants by such Indemnified Person or its affiliates contained herein or in the other agreements with the
Company. Expenses, including attorneys’ fees, incurred by any such Indemnified Person in defending a proceeding shall be paid by the Company as they are incurred and in advance of the final disposition of such action, suit or proceeding, upon
receipt of an undertaking by or on behalf of such Indemnified Person to repay such amount if it shall ultimately be determined by a court of competent jurisdiction that such Indemnified Person is not entitled to be indemnified by the Company. 

(b) The right to indemnification and the advancement of expenses conferred in this Section 18 shall not be exclusive
of any other right which any Indemnified Person may have or hereafter acquire under any statute, agreement, bylaw, action by the Managing Member or otherwise. 

(c) The Company shall maintain directors’ and officers’ liability insurance, or make other financial arrangements, at its expense,
to protect any Indemnified Person (and the investment funds, if any, they represent) against any expense, liability or loss described in Section 18(a) whether or not the Company would have the power to indemnify such
Indemnified Person against such expense, liability or loss under the provisions of this Section 18. The Company shall use its commercially reasonable efforts to purchase directors’ and officers’ liability
insurance (including employment practices coverage) with a carrier and in an amount determined necessary or desirable as determined in good faith by the Managing Member. 

(d) Notwithstanding anything contained herein to the contrary (including in this Section 18), the Company agrees
that any indemnification and advancement of expenses available to any current or former Indemnified Person from any investment fund that is an affiliate of the Company who served as a director of the Company or as a Member of the Company by virtue
of such Indemnified Person’s service as a member, director, partner or employee of any such fund prior to or following the date hereof (any such Indemnified Person, a “Sponsor Person”) shall be secondary to the indemnification
and advancement of expenses to be provided by the Company pursuant to this Section 18 which shall be provided out of and to the extent of Company assets only and no Member (unless such Member otherwise agrees in writing or
is found in a final decision by a court of competent jurisdiction to have personal liability on account thereof) shall have personal liability on account thereof or shall be required to make additional capital contributions to help satisfy such
indemnity of the Company and the Company (i) shall be the primary indemnitor of first resort for such Sponsor Person pursuant to this Section 18 and (ii) shall be fully responsible for the advancement of all
expenses and the payment of all damages or liabilities with respect to such Sponsor Person which are addressed by this Section 18. 

(e) If this Section 18 or any portion hereof shall be invalidated on any ground by any court of competent
jurisdiction, then the Company shall nevertheless indemnify and hold harmless each Indemnified Person pursuant to this Section 18 to the fullest extent permitted by any applicable portion of this
Section 18 that shall not have been invalidated and to the fullest extent permitted by applicable law.

 19. Governing Law. This Agreement shall be governed by, and construed in accordance
with, the laws of the State of Nevada, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Nevada or any other jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of Nevada. Any dispute relating hereto shall be heard in the state or federal courts of the State of Nevada, and the parties agree to jurisdiction and venue therein. 

20. Headings; Interpretation. The titles of the headings of the Sections of the Agreement are for convenience of reference only, and
are not to be considered in construing the terms and provisions of this Agreement. Reference herein to Sections shall be to Sections of this Agreement unless otherwise expressly provided.

Support Party represents and covenants that such Purchaser Support Party has not, in such Person’s capacity as a shareholder of the Purchaser, entered into, and shall not enter into, any agreement that would restrict, limit or interfere with
the performance of such Purchaser Support Party’s obligations under this Agreement. 

Section 1.9    Insider Letter. Other than in connection with the execution of and compliance with the Sponsor Lock-Up Agreement, neither the Purchaser Support Parties nor the Purchaser shall amend, terminate or otherwise modify the Insider Letter without the Company’s prior written consent. 

Section 1.10    Waiver of Anti-Dilution Provision. Subject to the consummation of the Transactions, each
Purchaser Support Party waives (for itself and for its successors, heirs and assigns), to the fullest extent permitted by law and the amended and restated memorandum and articles of association of the Purchaser (as may be amended from time to time,
the “Articles”), all anti-dilution rights that would otherwise result in Purchaser Class B Ordinary Shares held by such Purchaser Support Party converting into Purchaser Class A Ordinary Shares on a greater than one-for-one basis in connection with the Transactions. The waiver specified in this Section 1.10 shall be applicable only in connection with the
Transactions and the transactions contemplated by this Agreement and any Purchaser Class A Ordinary Shares, shares of Domesticated Purchaser Class A Common Stock or equity-linked securities issued in connection with the Transactions and
the transactions contemplated by this Agreement. If the Business Combination Agreement shall be terminated for any reason, the foregoing waiver shall be void and of no force and effect. 

Section 1.11    Sponsor Surrendered Securities. Effective immediately prior to the Domestication (and
contingent upon the Domestication and the Closing), each Purchaser Support Party will surrender to the Purchaser for cancellation and for no consideration such Purchaser Support Party’s Pro Rata Share of the Sponsor Surrendered Securities. 

Section 1.12    Purchaser Support Parties Indemnity. For a period of six years after the Closing Date, the
Company will indemnify, exonerate and hold harmless each Purchaser Support Party and such Person’s respective members, partners, managers and officers from and against all third-party actions, causes of action, suits, claims, liabilities,
losses, damages and costs and out-of-pocket expenses in connection with such third-party actions, causes of actions, suits, claims, liabilities, losses, damages and
costs (including reasonable attorneys’ fees and expenses) (“Indemnified Liabilities”) incurred by such Purchaser Support Party on or after the date of this Agreement, arising out of any third-party action, cause of action, suit,
litigation, investigation, inquiry, arbitration or claim arising from or relating to this Agreement, the entry by such Purchaser Support Party into this Agreement and the compliance with such Purchaser Support Party’s obligations in this
Agreement, in any such case, that names such Purchaser Support Party as a defendant (or co-defendant). The preceding sentence shall not apply to: (a) any Indemnified Liabilities to the extent arising out
of any breach by such Purchaser Support Party or such Person’s members, managers and officers of this Agreement or any other agreement between such Purchaser Support Party or such Person’s members, managers and officers, on the one hand,
and 

  
 5 

 
the Company or any of its subsidiaries, on the other hand; or (b) the willful misconduct, gross negligence or fraud of such Purchaser Support Party or such Person’s members, managers
and officers. 
 Section 1.13    Sponsor Earn-Out Securities. 

(a)    Upon and subject to the Closing, each Purchaser Support Party’s Pro Rata Share of the Sponsor Earn Out
Securities will be subject to vesting and potential forfeiture in accordance with the terms of this Agreement. The Sponsor Earn Out Securities shall vest as follows: 

i.    upon the occurrence of Triggering Event I, fifty percent (50%) of the Sponsor Earn Out Securities
shall vest to the Purchaser Support Parties in accordance with each Purchaser Support Party’s Pro Rata Share (the “Triggering Event I Sponsor Earn Out Securities”); and 

ii.    upon the occurrence of Triggering Event II, fifty percent (50%) of the Sponsor Earn Out Securities
shall vest to the Purchaser Support Parties in accordance with each Purchaser Support Party’s Pro Rata Share (the “Triggering Event II Sponsor Earn Out Securities”). 

(b)    The Sponsor Earn Out Securities shall be adjusted as appropriate to reflect any stock splits, reverse stock splits,
stock dividends, extraordinary cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction with respect to shares of Domesticated Purchaser Common Stock occurring on or after
the Closing. Stock dividends shall include any dividend or distribution of securities convertible into shares of Domesticated Purchaser Common Stock. The adjustments made pursuant to this Section 1.13(b) shall be subject to
the reasonable mutual agreement of the Purchaser and the Company. The Triggering Events may be achieved at the same time or over the same overlapping Trading Days. 

(c)    If the Sponsor Earn Out Units do not vest in accordance with this Section 1.13 during the
Earn Out Period, the obligations in Section 1.13(a), Section 1.13(e) and Section 1.13(f) shall terminate and no longer apply. In such event, the applicable Sponsor Earn
Out Securities that would have vested (but did not vest during such period) pursuant to Section 1.13(a), Section 1.13(e) and Section 1.13(f) shall be automatically
forfeited and deemed transferred to the Purchaser and shall be cancelled by the Purchaser and cease to exist. 

(d)    Notwithstanding anything to the contrary contained in this Agreement, Sponsor Earn Out Securities that vest in
accordance with this Section 1.13 shall remain subject to any other vesting or forfeiture conditions contained in any other agreements to which the holder is subject. 

(e)    If, following the Closing and prior to the third anniversary of the Closing, there is a Change of Control,
Triggering Event I and Triggering Event II shall be deemed to occur. In such event, all Sponsor Earn Out securities shall vest to the Purchaser Support Parties in accordance with each Purchaser Support Party’s Pro Rata Share. Such vesting shall
occur immediately prior to the closing of such Change of Control, and the Purchaser Support Parties shall be eligible to participate in such Change of Control. 

  
 6 

 (f)    If, following the third anniversary of the Closing and prior to
the expiration of the Earn Out Period, there is a Change of Control: 
 i.    that will result in the
holders of Domesticated Purchaser Class A Common Stock receiving a per share price equal to or in excess of $12.50, then to the extent Triggering Event I has not occurred prior to such Change of Control, Triggering Event I shall be deemed to
occur. In such event, such Sponsor Earn Out Securities shall vest to the Purchaser Support Parties in accordance with each Purchaser Support Party’s Pro Rata Share. Such vesting shall occur immediately prior to the closing of such Change of
Control, and the Purchaser Support Parties shall be eligible to participate in such Change of Control; and 

ii.    that will result in the holders of Domesticated Purchaser Class A Common Stock receiving a per
share price equal to or in excess of $15.00, then to the extent Triggering Event II has not occurred prior to such Change of Control, Triggering Event II shall be deemed to occur. In such event, such Sponsor Earn Out Securities shall vest to the
Purchaser Support Parties in accordance with each Purchaser Support Party’s Pro Rata Share. Such vesting shall occur immediately prior to the closing of such Change of Control, and the Purchaser Support Parties shall be eligible to participate
with respect thereto in such Change of Control. 
 (g)    Each Purchaser Support Party shall be entitled to vote the
Sponsor Retained Shares constituting Sponsor Earn Out Securities and receive dividends and other distributions in respect of such Sponsor Earn Out Securities prior to the vesting of such Sponsor Earn Out Securities in accordance with the terms of
this Agreement. Notwithstanding the foregoing, any such dividends and other distributions in respect of the Sponsor Retained Shares constituting Sponsor Earn Out Securities that are subject to vesting pursuant to the terms of this Agreement shall be
set aside by the Company and shall only be paid to the holder of such Sponsor Earn Out Securities upon the vesting of such Sponsor Earn Out Securities. 

(h)    Unless such Transfer constitutes a “Permitted Transfer” (as defined in Section 2 of the Sponsor Lock-Up Agreement), prior to the date that a Sponsor Earn Out Security vests in accordance with this Section 1.13, without the prior written consent of the Company, no Purchaser Support
Party shall Transfer such Sponsor Earn Out Security. 
 The per share price received by the holders of Domesticated Purchaser Class A Common Stock
shall be based on the value of the cash, securities or in-kind consideration being delivered in respect of such Domesticated Purchaser Class A Common Stock, as determined in good faith by the board of
directors of the Purchaser. Such per share price shall be adjusted as appropriate to reflect any stock splits, reverse stock splits, stock dividends, including any dividend or distribution of securities convertible into Domesticated Purchaser
Class A Common Stock, extraordinary cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction with respect to Domesticated Purchaser Class A Common Stock
occurring on or after the Closing. Any adjustments made pursuant to Section 1.13(f)i and Section 1.13(f)ii shall be subject to the reasonable mutual agreement of the Purchaser and the Company.

REPRESENTATIONS AND WARRANTIES 

Section 2.1    Representations and Warranties of the Purchaser Support Parties. Each Purchaser Support Party,
severally and not jointly, represents and warrants as of the Effective Date to the Purchaser and the Company, in each case, only with respect to itself, as follows: 

(a)    Organization; Due Authorization. If the Purchaser Support Party is an individual, such Person has all the
requisite power and authority and has taken all action necessary in order to execute and deliver this Agreement, to perform such Person’s obligations under this Agreement and to consummate the transactions contemplated by this Agreement. If the
Purchaser Support Party is not an individual: (i) such Person is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which such Person is incorporated, formed, organized or constituted; and (ii) the
execution, delivery and performance of this Agreement and the consummation of the transactions contemplated by this Agreement are within such Purchaser Support Party’s corporate, limited liability company, partnership or similar organizational
powers and have been duly authorized by all necessary corporate, limited liability company, partnership or similar organizational actions on the part of such Purchaser Support Party. This Agreement has been duly executed and delivered by such
Purchaser Support Party. Assuming the due authorization, execution and delivery by the other parties to this Agreement, this Agreement constitutes a legally valid and binding obligation of such Purchaser Support Party. Except as enforceability may
be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of specific performance and other equitable remedies, this Agreement is enforceable against such Purchaser
Support Party in accordance with its terms. If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to enter into this Agreement on behalf of such Purchaser
Support Party. 
 (b)    Ownership. Such Purchaser Support Party is the record and beneficial owner (as defined
in Rule 13d-3 of the Exchange Act) of, and has good title to, all of such Person’s respective Subject Securities. There exist no Liens or any other limitation or restriction affecting any such Subject
Securities, other than Liens pursuant to: (i) this Agreement; (ii) the Purchaser’s Organizational Documents; (iii) the Business Combination Agreement; (iv) the Insider Letter; (v) the Sponsor’s Organizational
Documents; (vi) agreements between such Purchaser Support Party and such Purchaser Support Party’s members or Affiliates, as applicable; (vii) the Sponsor Lock-Up Agreement; or (viii) any
applicable securities Laws. Such Purchaser Support Party’s Subject Securities are the only equity securities of the Purchaser owned of record or beneficially by such Purchaser Support Party on the Effective Date. Except as provided under this
Agreement and the Insider Letter, none of such Subject Securities are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Subject Securities. Other than the Purchaser Warrants held by such
Purchaser Support Party, such Purchaser Support Party does not hold or own any rights to acquire (directly or indirectly) any equity securities of the Purchaser or any equity securities convertible into, or which can be exchanged for, equity
securities of the Purchaser. 

  
 9 

 (c)    No Conflicts. The execution and delivery of this Agreement
by such Purchaser Support Party does not, and the performance by such Purchaser Support Party of such Person’s obligations under this Agreement will not: (i) if such Purchaser Support Party is not an individual, conflict with or result in
a violation of the organizational documents of such Purchaser Support Party; or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such
Purchaser Support Party or such Purchaser Support Party’s Subject Securities), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Purchaser Support Party of such
Person’s obligations under this Agreement. 
 (d)    Litigation. There are no Legal Proceedings pending
against such Purchaser Support Party, or to the knowledge of such Purchaser Support Party threatened against such Purchaser Support Party, before (or, in the case of threatened Legal Proceedings, that would be before) any arbitrator or any
Governmental Authority, that in any manner challenge or seek to prevent, enjoin or materially delay the performance by such Purchaser Support Party of such Person’s obligations under this Agreement. 

(e)    Brokerage Fees. Except as set forth on Section 5.15 (Finders and Brokers) of the Purchaser
Disclosure Letter, no broker, finder, financial advisor, investment banker or other Person is entitled to any brokerage fee, finders’ fee or other commission in connection with the Transactions based upon arrangements made by such Purchaser
Support Party, for which the Purchaser or any of such Person’s Affiliates may become liable. 

(f)    Acknowledgement. Such Purchaser Support Party understands and acknowledges that each of the Purchaser and
the Company is entering into the Business Combination Agreement in reliance upon the Purchaser Support Party’s execution and delivery of this Agreement.

force or effect upon the earliest of: (a) the BCA Termination; (b) the liquidation of the Purchaser; and (c) the written agreement of the Purchaser Support Parties, the Purchaser and the Company. Upon such termination of this
Agreement: (i) all obligations of the parties under this Agreement will terminate, without any liability or other obligation on the part of any party to this Agreement to any Person with respect to this Agreement or the transactions
contemplated by this Agreement; and (ii) no party to this Agreement shall have any claim against another (and no Person shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter of
this Agreement. Notwithstanding the foregoing, the termination of this Agreement shall not relieve any party to this Agreement from liability arising in respect of any breach of this Agreement prior to such termination. Notwithstanding the
foregoing, if the Closing occurs, Section 1.13 and Section 1.14 shall survive until the earlier of: (a) thirty days following the expiration of the Earn Out Period; and (b) such time as

 10 

 Section 3.2    No Recourse. This Agreement may only be
enforced against, and any action for breach of this Agreement may only be made against, the parties to this Agreement. No claims of any nature whatsoever (whether in tort, contract or otherwise) arising under or relating to this Agreement, the
negotiation of this Agreement or its subject matter, or the transactions contemplated by this Agreement shall be asserted against any Non-Party Affiliate. Except to the extent liable in such Person’s
capacity as a party to this Agreement, no Non-Party Affiliates shall have any liability arising out of or relating to this Agreement, the negotiation of this Agreement or its subject matter, or the
transactions contemplated by this Agreement, including: (a) with respect to any claim (whether in tort, contract or otherwise) for breach of this Agreement; (b) in respect of any written or oral representations made or alleged to be made
in connection with this Agreement; (c) as expressly provided in this Agreement; or (d) for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished in connection with
this Agreement, the negotiation of this Agreement or the transactions contemplated by this Agreement. “Non-Party Affiliate” means: (i) any officer, director, employee, partner, member,
manager, direct or indirect equityholder or Affiliate of each of the Company, the Purchaser, the Sponsor or any of the Purchaser Support Parties; and (ii) each of the former, current or future Affiliates, Representatives, successors or
permitted assigns of any of the Persons referred to in the immediately preceding clause (i) (other than the parties to this Agreement). 

Section 3.3    Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary: (a) no
Purchaser Support Party makes any agreement or understanding in this Agreement in any capacity other than in such Purchaser Support Party’s capacity as a record holder and beneficial owner of such Person’s respective Subject Securities;
and (b) nothing in this Agreement will be construed to limit or affect any action or inaction expressly permitted under the Business Combination Agreement by any Purchaser Support Party or any representative of such Purchaser Support Party in
such Person’s capacity as a member of the board of directors (or other similar governing body) of the Purchaser or as an officer, employee or fiduciary of the Purchaser or an Affiliate of the Purchaser. 

Section 3.4    Assignment. This Agreement and all of the provisions of this Agreement shall be binding upon
and inure to the benefit of the parties to this Agreement and their respective heirs, successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations under this Agreement will be assigned (including by
operation of law) without the prior written consent of the parties to this Agreement. Any assignment without such consent shall be null and void. 

Section 3.5    Specific Performance. The parties to this Agreement acknowledge and agree that irreparable
damage may occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. In addition to any other remedy to which such party is entitled at law or in equity,
the parties to this Agreement shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement. In the event that any action shall be brought in
equity to enforce the provisions of this Agreement, no party shall allege, and each party waives the defense, that there is an adequate remedy at law. Each party agrees to waive any requirement for the securing or posting of any bond in connection
with such action. 

  
 11 

 Section 3.6    Jurisdiction. Any Legal Proceeding based
upon, arising out of or related to this Agreement or the transactions contemplated by this Agreement must be brought in the Court of Chancery of the State of Delaware and any State of Delaware appellate court therefrom (or, but only to the extent
the Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties irrevocably: (i) submits to the exclusive jurisdiction of each such court in any such
Legal Proceeding; (ii) waives any objection such party may now or after this Agreement have to personal jurisdiction, venue or to convenience of forum; (iii) agrees that all claims in respect of the Legal Proceeding shall be heard and
determined only in any such court; and (iv) agrees not to bring any Legal Proceeding arising out of or relating to this Agreement or the transactions contemplated by this Agreement in any other court. Nothing in this Agreement shall be deemed
to affect the right of any party to serve process in any manner permitted by Law or to commence Legal Proceedings or otherwise proceed against any other party in any other jurisdiction, in each case, to enforce judgments obtained in any Legal
Proceeding brought pursuant to this Section 3.6. 
 Section 3.7    Amendment. This
Agreement may not be amended, changed, supplemented, waived or otherwise modified or terminated, except upon the execution and delivery of a written agreement executed by the Purchaser, the Company and the Purchaser Support Parties.

not joint). Notwithstanding any other provision of this Agreement, in no event will any Purchaser Support Party be liable for any other Purchaser Support Party’s breach of such other Purchaser Support Party’s obligations under this
Agreement. 
 Section 3.10    Disclosure. Each Purchaser Support Party authorizes the Purchaser and the
Company to publish and disclose in any announcement or disclosure relating to the Transactions, including any such announcement or disclosure required or requested by the SEC (or as otherwise required or requested pursuant to any applicable Laws or
any other Governmental Authorities), such Purchaser Support Party’s identity and ownership of the Subject Securities, the nature of such Purchaser Support Party’s obligations under this Agreement and a copy of this Agreement, if reasonably
