transaction, the surviving entity of the First Merger will merge with and into Merger Sub II (the “Second Merger” and, together with the First Merger, the “Mergers”), with Merger Sub II surviving the Second Merger
as a wholly owned subsidiary of the Company; 
 WHEREAS, prior to the consummation of the Mergers, the Company shall effect the
Recapitalization (as defined in the Merger Agreement); 
 WHEREAS, in connection with the consummation of the Mergers, Subscriber desires to
purchase, following the Recapitalization, that number of Class A Ordinary Shares (as defined in the Merger Agreement) (the “Class A Shares”) as set forth on the signature page hereto (the “Acquired
Shares”) for a purchase price of $10.00 per share and an aggregate purchase price set forth on the signature page hereto (the “Purchase Price”); 

WHEREAS, the Company desires to arrange for the purchase by Subscriber of the Acquired Shares, at the Company’s election pursuant to this
Agreement, through (a) the issuance of all or a portion of the Acquired Shares (the “Primary Shares”) by the Company to Subscriber at a per share price equal to $10.00 (the “Primary Purchase Price”) to the
Company by or on behalf of Subscriber and/or (b) the sale of all or a portion of the Acquired Shares (the “Secondary Shares”) by one or more holders of Class A Shares (each, a “Secondary Seller” and

Subscribers”) have, severally and not jointly, entered into separate investment agreements with the Company with substantially similar terms to this Agreement (each such investment agreement, other than any investment agreement between the
Company and SPAC (if any), the “Other Investment Agreements”), pursuant to which such investors have agreed to purchase Class A Shares on the Closing Date (as defined below) at a per share price of $10.00 per share (the
“Per Share Purchase Price”). 












 NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties
and covenants, and subject to the conditions, herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto hereby agree as
follows: 
 1. Commitment; Company Election. 

(a) Subject to the terms and conditions hereof, Subscriber hereby commits to purchase the Acquired Shares immediately prior to the consummation
of the Mergers from the Company or the Secondary Sellers, as and to the extent set forth in the Election Notice (as defined below). 
 (b)
Within five (5) business days following the completion of the SPAC Extraordinary General Meeting (as defined in the Merger Agreement), the Company shall deliver a written notice (the “Election Notice”) to Subscriber stating
(i) the number of Primary Shares (if any) to be acquired by Subscriber (the “Primary Share Number”) and the Primary Purchase Price (as defined below) and (ii) the number of Secondary Shares (if any) to be acquired by
Subscriber (the “Secondary Share Number”), the Secondary Purchase Price (as defined below) and the identity of the Secondary Seller(s). The number of Primary Shares and Secondary Shares to be purchased by Subscriber shall be
determined by the Company in its sole discretion; provided that, for the avoidance of doubt, (A) the aggregate number of Primary Shares and Secondary Shares shall equal the Acquired Shares and (B) the Primary Purchase Price,
together with the Secondary Purchase Price, shall equal the Purchase Price. For purposes of this Agreement (1) “Primary Purchase Price” means the Primary Share Number multiplied by $10.00, and (2) “Secondary Purchase
Price” means the Secondary Share Number multiplied by $10.00. 
 2. Subscription; Purchase and Sale. 

(a) To the extent the Election Notice provides for the sale of Primary Shares to Subscriber, subject to the terms and conditions hereof,
Subscriber hereby subscribes for and agrees to purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Primary Purchase Price, such number of Primary Shares equal to the Primary Share Number (such

hereto as Exhibit A (each, a “Secondary Purchase Agreement” and collectively, the “Secondary Purchase Agreements”) (such purchase and sale of the Secondary Shares, the “Purchase and Sale”).
The Company agrees to effect and reflect the transfer of the Secondary Shares pursuant to the Secondary Purchase Agreements from the Secondary Sellers to Subscriber on its books. For the avoidance of doubt, to the extent the Election Notice provides
for the sale of Secondary Shares by one or more Secondary Sellers to Subscriber and not for the sale of Primary Shares to Subscriber pursuant to this Agreement, all representations, warranties, covenants and agreements of the Company set forth in
this Agreement shall remain in full force and effect.

procedures reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors against the OFAC Lists. Subscriber further represents and warrants that, to the extent applicable to
Subscriber, it maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Acquired Shares were legally derived. 

(p) If Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended

defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal,
state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code, or an entity whose underlying assets are considered to include “plan assets” of any such
plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or section 4975 of the Code, Subscriber represents and warrants that (i) neither the Company, the Secondary
Sellers, nor any of their respective affiliates (the “Transaction Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Acquired Shares, and
none of the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Acquired Shares; (ii) the decision to invest in the Acquired Shares has been

(q) Subscriber has, and on and as of the Funding Date will have, sufficient funds to pay the Purchase Price pursuant to
Section 2. 

  
 13 













 (r) Subscriber does not have, as of the date hereof, and during the 30-day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position,” as such term is defined in Rule 16a-1 under the
Exchange Act, or short sale positions, with respect to the securities of the Company. Notwithstanding the foregoing, (i) in the case of a Subscriber that has other entities under common management with Subscriber that have no knowledge of this
Agreement or of Subscriber’s participation in the Mergers (including Subscriber’s affiliates), the representation set forth above shall not apply to such other entities and (ii) in the case of a Subscriber that is a multi-managed
investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions
of such Subscriber’s assets, the representation set forth in this Section 6(r) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
Acquired Shares. In no event shall any affiliate or associate of Subscriber be deemed to be a party to this Agreement. 
 7. Registration
Rights. 
 (a) The Company agrees that, as soon as practicable but in no event later than thirty (30) calendar days after the
Closing Date (the “Filing Deadline”), the Company will file with the United States Securities and Exchange Commission (the “Commission”) (at the Company’s sole cost and expense) a registration statement
registering the resale of the Registrable Securities (as defined below) (the “Registration Statement”), and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as
practicable after the filing thereof (but, shall use its commercially reasonable efforts to have the Registration Statement declared effective no later than the earlier of (i) the ninetieth (90th) calendar day (or one hundred and twentieth
(120th) calendar day if the Commission notifies the Company that it will “review” the Registration Statement) following the Closing and (ii) the seventh (7th) business day after the date the Company is notified (orally or in writing,
whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review) (any such date, the “Effectiveness Deadline”); provided, however, that if the
Commission is closed for operations due to a government shutdown and the Company is unable to cause the Registration Statement to be declared effective as a result, the Effectiveness Deadline shall be extended by the same amount of days that the
Commission remains closed for operations, provided, further, that the Company’s obligations to include the Registrable Securities for resale in the Registration Statement are contingent upon Subscriber furnishing in writing to the
Company such information regarding Subscriber, the securities of the Company held by Subscriber, including, but not limited to, the Registrable Securities held by Subscriber, and the intended method of disposition of the Registrable Securities as
shall be reasonably requested by the Company to effect the registration of the Class A Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a
selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted
hereunder; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the
ability to transfer the Registrable Securities. Any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise


  
 14 













 
relieve the Company of its obligations to file or effect the Registration Statement as set forth above in this Section 7. The Company will provide a draft of the
Registration Statement to Subscriber for review at least two (2) business days in advance of filing the Registration Statement. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless
specifically requested by the Commission or another regulatory agency; provided, that if the Commission or another regulatory agency requests that a Subscriber be identified as a statutory underwriter in the Registration Statement, such Subscriber
will have the opportunity to withdraw from the Registration Statement upon its prompt written request to the Company. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be
registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities by the applicable shareholders or otherwise, such Registration Statement shall register for
resale such number of Registrable Securities which is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of Registrable Securities to be registered for each selling shareholder named in
the Registration Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable after being permitted to register additional Registrable Securities under Rule 415 of the Securities Act, the Company shall file
a new Registration Statement to register such Registrable Securities not included in the initial Registration Statement and cause such Registration Statement to become effective as promptly as practicable. The Company will use its commercially
reasonable efforts to maintain the continuous effectiveness of the Registration Statement until all such securities cease to be Registrable Securities or such shorter period upon which Subscriber has notified the Company that Subscriber’s
Registrable Securities included in such Registration Statement have actually been sold. The Company will file all reports, and provide all customary and reasonable cooperation, necessary to enable Subscriber to resell Registrable Securities pursuant
to the Registration Statement or Rule 144, as applicable, qualify the Registrable Securities for listing on the applicable stock exchange, update or amend the Registration Statement as necessary to include Registrable Securities and provide
customary notice to holders of Registrable Securities. “Registrable Securities” shall mean, as of any date of determination, the Acquired Shares and any other equity security of the Company issued or issuable with respect to the
Acquired Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise. For the avoidance of doubt, any references in this Section 7 to Subscriber shall
include Subscriber’s permitted assignee(s) from and after any such assignment. 
 (b) In the case of the registration, qualification,
exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and compliance. At its expense, the Company
shall: 
 (i) except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a
Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective with respect to
Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earliest of the following: (i) Subscriber ceases to hold any Registrable
Securities, (ii) the date all Registrable Securities held by Subscriber may be sold without restriction under Rule 144, including any 

  
 15 













 
volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for the Company to be in compliance with the current public information
required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), (iii) when all Registrable Securities held by Subscriber cease to be outstanding and (iv) three (3) years from the effective date of the Registration Statement. 

(ii) advise Subscriber (or, if directed by Subscriber in writing, its counsel) within three (3) business days: 

(1) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any
post-effective amendment thereto has become effective; 
 (2) of any request by the Commission for amendments or supplements to any
Registration Statement or the prospectus included therein or for additional information; 
 (3) after it shall receive notice or obtain
knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; 

(4) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities
included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 
 (5) subject to the
provisions in this Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus included therein so that, as of such date, the statements therein are not misleading and do not omit to
state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading. 

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide
Subscriber with any material, nonpublic information regarding the Company other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (1) through (5) above constitutes material, nonpublic
information regarding the Company and Subscriber hereby consents to the receipt of such notice; 
 (iii) use its commercially reasonable
efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable; 

(iv) upon the occurrence of any event contemplated above, except for such times as the Company is permitted hereunder to suspend, and has
suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a
supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; 

  
 16 













 (v) use its commercially reasonable efforts to cause all Registrable Securities to be
listed on each securities exchange or market, if any, on which the Class A Shares issued by the Company have been listed; and 
 (vi)
use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and to enable Subscriber to sell the Registrable Securities under Rule 144. 

(c) Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled to delay or postpone the effectiveness of the
Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if it determines, in each case in good faith and its reasonable judgment after consultation
with counsel to the Company, that in order for the Registration Statement not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading, (i) an
amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a transaction by the Company or
its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Company’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the
Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the
reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (iii) in the good faith judgment of the
majority of Company’s board of directors, upon advice of counsel, such filing or effectiveness or use of such Registration Statement, would be materially adverse to the Company and the majority of the Company’s board of directors concludes
as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend the Registration Statement on more than two occasions
or for more than forty-five (45) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Company of the happening of any Suspension Event
during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or prospectus contained therein contains any untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue
offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Company
agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and
sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the 

  
 17 













 
Company unless otherwise required by law or subpoena (provided Subscriber may disclose such information to its representatives or affiliates who have agreed to maintain the confidentiality of
such information). Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of a Suspension Event, provide Subscriber with any material, nonpublic information regarding the Company (other than to
the extent that providing notice to Subscriber of the occurrence of a Suspension Event may itself constitute material, nonpublic information regarding the Company and Subscriber hereby consents to the receipt of such notice). If so directed by the
Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in Subscriber’s possession; provided, however, that this obligation to
deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (A) to the extent Subscriber is required to retain a copy of such prospectus (1) in order to comply with applicable legal, regulatory,
self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival servers as a result of
automatic data back-up. 
 (d) The Company shall, notwithstanding any termination of this Agreement,
indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), the officers, directors, trustees, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of each of
them, each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling person, to the fullest extent
permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise
out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or
in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus
or supplement thereto, in light of the circumstances under which they were made) not misleading, except insofar as and to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are
based solely upon information regarding Subscriber furnished in writing to the Company by or on behalf of the Subscriber expressly for use therein. The Company shall notify Subscriber promptly of the institution, threat or assertion of any
proceeding arising from or in connection with the transactions contemplated by this Section 7 of which the Company is aware. 
 (e)
Subscriber shall, severally and not jointly with any Other Subscriber, indemnify and hold harmless the Company, its directors, officers, agents and employees, each person who controls the Company (within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are
based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case 

  
 18 













 
of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such
untrue statements or omissions are based solely upon information regarding Subscriber furnished in writing to the Company by or on behalf of Subscriber expressly for use therein. In no event shall the liability of Subscriber under this
Section 7(e) be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation. Subscriber shall notify the Company promptly of the
institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 7(e) of which Subscriber is aware. 

(f) Any person or entity entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not materially prejudiced the
indemnifying party) and (2) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the
defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but
such counsel shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in
addition to local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest may exist between such indemnified party
and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party (which consent shall not be unreasonably withheld), consent to the entry of any judgment or enter into
any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and
culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

 (g) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or
on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Acquired Shares purchased pursuant to this Agreement. 

(h) If the indemnification provided under this Section 7 from the indemnifying party is unavailable or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable
by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact


  
 19 













 
or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying
party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above
shall be deemed to include, subject to the limitations set forth in this Section 7, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No
person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7(h) from any person who was not guilty of such
fraudulent misrepresentation. Any contribution pursuant to this Section 7(h) by any seller of Acquired Shares shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Acquired
Shares giving rise to such contribution obligation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 7(h) shall be several, not joint. 

(i) For purposes of this Section 7, “Subscriber” shall include any person to whom the rights under this
Section 7 have been duly assigned in accordance with this Agreement. 
 8. Termination. This Agreement shall terminate and be
void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as
the Merger Agreement is validly terminated in accordance with its terms prior to the consummation of the Mergers, (b) upon the mutual written agreement of each of the parties hereto, or (c) at the election of Subscriber, thirty
(30) days after the Termination Date (as defined in the Merger Agreement as of the date hereof) if the Primary Closing or the Secondary Closing, as applicable, has not occurred other than as a result of a breach of Subscriber’s obligations
hereunder; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities
or damages arising from such willful breach. The Company shall promptly notify Subscriber in writing of the termination of the Merger Agreement.    Upon the termination of this Agreement, if the Primary Purchase Price or
Secondary Purchase Price has been paid by the Subscriber, the Company agrees to promptly (and in any event within one (1) Business Day) return, or cause to be returned, the entire Primary Purchase Price and/or the Secondary Purchase Price to
the Subscriber in full, without deduction or penalty. 
 9. No Hedging. Subscriber hereby agrees that neither it, nor any person or
entity acting on its behalf or pursuant to any understanding with it, shall execute any short sales or engage in other hedging transactions of any kind with respect to the Acquired Shares during the period from the date of this Agreement through the
Closing (or such earlier termination of this Agreement in accordance with its terms). Nothing in this Section 9 shall prohibit such persons from engaging in hedging transactions with respect to other securities of the
Company, including Class A Shares acquired in open market purchases, so long as such person does not create any “put equivalent position,” as such term is defined in Rule 16a-1 under the
Exchange Act, or short sale positions, with respect to the Acquired Shares. Notwithstanding the foregoing, (i) nothing herein shall prohibit any entities under common management with Subscriber that have no knowledge of this Agreement or of
Subscriber’s participation in the transactions contemplated hereby (including Subscriber’s controlled affiliates and/or affiliates) from entering into any short sales; (ii) in the case of a Subscriber that is a multi-managed
investment vehicle whereby separate portfolio 

  
 20 













 
managers manage separate portions of such Subscriber’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions
of such Subscriber’s assets, this Section 9 shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Acquired Shares covered by this
Agreement. 
 10. Covenants of the Company  

(a) With a view to making available to Subscriber the benefits of Rule 144 or any other similar rule or regulation of the Commission that may
at any time permit Subscriber to sell securities of the Company to the public without registration, the Company agrees, until the Acquired Shares are registered for resale under the Securities Act, to: 

(i) make and keep public information available, as those terms are understood and defined in Rule 144; 

(ii) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the
Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and 

(iii) furnish to Subscriber so long as it owns Acquired Shares, promptly upon request, (A) a written statement by the Company, if true,
that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (B) a copy of the most recent annual report of the Company and such other reports and documents so filed by the Company and (C) such
other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration. 

(b) The legend described in Section 6(f) shall be removed and the Company shall issue a certificate without such
legend to the holder of the Acquired Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at The Depository Trust Company (“DTC”), if (i) such Acquired Shares are
registered for resale under the Securities Act, (ii) in connection with a sale, assignment or other transfer, such holder provides the Company with an opinion of counsel, in a form reasonably acceptable to the Company, to the effect that such
sale, assignment or transfer of the Acquired Shares may be made without registration under the applicable requirements of the Securities Act, or (iii) the Acquired Shares can be sold, assigned or transferred pursuant to Rule 144, and
(1) in each case, the holder provides the Company with an undertaking to effect any sales or other transfers in accordance with the Securities Act and (2) with respect to clauses (i) and (iii), upon the Company providing the Transfer
Agent with such certifications as reasonably requested, which the Company undertakes to provide. The Company shall be responsible for the fees of its transfer agent and all DTC fees associated with such issuance.

 11. Miscellaneous. 

(a) Each party hereto acknowledges that the other party hereto will rely on the acknowledgments, understandings, agreements, representations
and warranties expressly set forth in this Agreement. Prior to the Closing, each party hereto agrees to promptly notify the other party hereto if any of the acknowledgments, understandings, agreements, representations and warranties set forth herein
with respect to it are no longer accurate in all material respects. Subscriber further acknowledges and agrees that the Placement Agents are third-party beneficiaries of the representations and warranties of Subscriber contained in this Agreement.

 (b) Each of the Company and Subscriber is entitled to rely upon this Agreement and is irrevocably authorized to produce this Agreement or
a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby. The Placement Agents are entitled to rely upon the representations and warranties made by Subscriber in
this Agreement. 
 (c) All the representations and warranties made by each party hereto in this Agreement shall survive the Closing for a

 (d) The Company may request from Subscriber such additional information as the Company
may deem reasonably necessary to evaluate the eligibility of Subscriber to acquire the Acquired Shares, and Subscriber shall provide such information as may be reasonably requested, to the extent readily available; provided that the Company

Company with such requested information, Subscriber’s Acquired Shares may not be able to be registered for resale. Subscriber acknowledges that a copy of this Agreement may be filed as exhibit to a periodic report or registration statement.

 (f) This
Agreement (including Schedule A hereto and, if applicable, the Secondary Purchase Agreement) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral,
among the parties, with respect to the subject matter hereof.

consent of the Company, provided that such assignee(s) agrees in writing to be bound by the terms hereof, including making the representations and warranties set forth in Section 6. Upon such assignment by a Subscriber, the
assignee(s) shall 

  
 22 













 become Subscriber hereunder and have the rights and obligations provided for herein to the extent of such
assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any assignment to any fund or account managed by the same investment manager or investment advisor as Subscriber or by
an affiliate of such investment manager or investment advisor, unless consented to in writing by the Company. Neither this Agreement nor any rights that may accrue to the Company hereunder or any of the Company’s obligations may be transferred
or assigned other than pursuant to the Mergers. 
 (h) If any provision of this Agreement shall be adjudicated by a court of competent
jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

 (p) This Agreement, and any claim or cause of action hereunder based upon, arising out of or
related to this Agreement or the transactions contemplated by this Agreement, shall be governed by, and construed in accordance with, the internal substantive laws of the State of Delaware applicable to contracts entered into and to be performed
solely within such state, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the laws of another jurisdiction. Any claim or cause of action based upon,
arising out of or related to this Agreement or transactions contemplated by this Agreement shall be brought in the Delaware Court of Chancery, and if the Delaware Court of Chancery does not have or take jurisdiction over such claim or cause of
action, any other federal or state courts located in the State of Delaware, and each of the parties hereto irrevocably submits to the exclusive jurisdiction of each such court in any such claim or cause of action, waives any objection it may now or

legal proceedings or otherwise proceed against any other party hereto in any other jurisdiction, in each case, to enforce judgments obtained in any claim or cause of action brought pursuant to this Section 11(p). EACH OF
THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 

(q) Subject to the Recapitalization, if any change in the number or type of equity securities of the Company shall occur between the date
hereof and immediately prior to the Primary Closing by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend, the number of Primary
Shares purchased by Subscriber and the price per share shall be appropriately adjusted to reflect such change. 
 (r) Subscriber has
delivered, or within five (5) business days prior to the Closing will deliver, to Company a duly executed IRS Form W-9 or applicable IRS Form W-8, and will provide
any other tax-related documentation or information reasonably requested by the Company. 
 (s) The
Company shall, by 9:00 a.m., New York City time, on the first (1st) business day immediately following the date of this Agreement, issue one or more press releases or file with the Commission a Current Report on Form
8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Investment Agreements, the Mergers and any other material,
nonpublic information that the Company or SPAC has provided to Subscriber at any time prior to the filing of the Disclosure Document. Upon the issuance of the Disclosure Document, Subscriber shall not be in possession of any material, non-public information received from the Company, SPAC or any of their respective officers, directors or employees or agents (including the Placement Agents) and Subscriber shall no longer be subject to any
confidentiality or similar obligations under any agreement, whether written or oral, relating to the transactions contemplated by this Agreement or otherwise. The Company understands and confirms that the Subscriber and its affiliates will rely


  
 25 













 on the foregoing representations in effecting transactions in securities of the Company. Notwithstanding
anything in this Agreement to the contrary, the Company shall not publicly disclose the name of Subscriber or any of its affiliates, or include the name of Subscriber or any of its affiliates in any press release or in any filing with the Commission
or any regulatory agency or trading market, without the prior written consent of Subscriber, except (i) as required by the federal securities law and (ii) to the extent such disclosure is required by law, at the request of the Staff of the
Commission or regulatory agency or under the regulations of the New York Stock Exchange, and in each such case, unless prohibited by law, rule or regulation, shall use its commercially reasonable efforts to provide Subscriber with prior written
notice (including by email) of such disclosure and shall use its commercially reasonable efforts to consult with Subscriber in advance as to its form, content and timing. 

(t) The Subscriber acknowledges that SPAC is a blank check company with the powers and privileges to effect a merger, asset acquisition,
reorganization or similar business combination involving SPAC and one or more businesses or assets. The Subscriber further acknowledges that, as described in SPAC’s prospectus relating to its initial public offering dated January 14, 2021
(the “Prospectus”) available at www.sec.gov, substantially all of SPAC’s assets consist of the cash proceeds of SPAC’s initial public offering and private placement of its securities, and substantially all of those
proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of SPAC, its public shareholders and the underwriters of SPAC’s initial public offering. Except with respect to interest earned on the funds
held in the Trust Account that may be released to SPAC to pay its tax obligations and to fund certain of its working capital requirements, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. The
Subscriber hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account as a
result of, or arising out of, this Agreement; provided, however, that nothing in this Section 11(t) shall be deemed to limit the Subscriber’s right, title, interest or claim to any monies held in the Trust Account by virtue
of its record or beneficial ownership of shares acquired by any means other than this Agreement, pursuant to a validly exercised redemption right with respect to any such shares, except to the extent that the Subscriber has otherwise agreed with
SPAC to not exercise such redemption right. 
 (u) For the avoidance of doubt, all obligations of the Subscriber under this Agreement are
separate and several from the obligations of Other Subscribers. The decision of Subscriber to purchase the Acquired Shares pursuant to this Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and
independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company, SPAC, or any of
their respective subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability
to any Other Subscriber or investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Investment Agreement, and no action taken by Subscriber or Other
Subscribers pursuant hereto or thereto, shall be deemed to constitute Subscriber and Other Subscribers or other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and
Other Subscribers or other investors are in any way acting in concert or as a group with respect 

  
 26 













 to such obligations or the transactions contemplated by this Agreement and the Other Investment Agreements.
Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the
Acquired Shares or enforcing its rights under this Agreement. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any
Other Subscriber or investor to be joined as an additional party in any proceeding for such purpose.

RECITALS 
 WHEREAS,
ironSource Ltd., a company organized under the laws of the State of Israel (the “Company”), has entered into that certain Agreement and Plan of Merger (as may be amended, supplemented or otherwise modified from time to time in

Seller’s name on Annex A hereto (with respect to each Seller, its “Seller Consideration”), all in accordance with the terms of the Investment Agreement and this Agreement. 

NOW, THEREFORE, in consideration of the foregoing premises and the undertakings herein contained and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 












 ARTICLE I 

INTERPRETIVE MATTERS 

Section 1.01 Construction. The parties to this Agreement have participated jointly in the negotiation and drafting of this
Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties to this Agreement, and no presumption or burden of proof shall arise favoring or disfavoring
any party by virtue of the authorship of any of the provisions of this Agreement. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation” and the words
“herein,” “hereof” and “hereunder” and words of similar import refer to this Agreement in its entirety and not to any part hereof unless the context shall otherwise require. All references to “or” shall be
construed in the inclusive sense of “and/or.” Any reference to any Person shall be deemed to refer to any successor or surviving entity by merger or consolidation and any permitted assigns. The headings in this Agreement are inserted for
convenience only and are in no way intended to describe, interpret, define, or limit the scope, extent or intent of this Agreement or any provision of this Agreement. Unless the context requires otherwise, all references in this Agreement to
Sections, Articles, Exhibits, Schedules or Annexes shall be deemed to mean and refer to Sections, Articles, Exhibits, Schedules or Annexes of or to this Agreement. 

ARTICLE II 
 PURCHASE
AND SALE 
 Section 2.01 Purchase and Sale. 

(a) Upon the terms and subject to the conditions set forth in this Agreement and the Investment Agreement, at the Closing, each Seller shall
severally sell, transfer, assign and deliver to Buyer, and Buyer shall purchase and acquire from each Seller, such Seller’s Seller Shares, free and clear of any and all liens, hypothecations, mortgages, pledges, security interests, options,
charges or other encumbrances or restrictions (“Liens”) (other than Liens arising under this Agreement or applicable Securities Laws (as defined in the Merger Agreement)), in exchange for such Seller’s Seller Consideration.

 (b) Upon the terms and subject to the conditions set forth in this Agreement and the Investment Agreement, payment by Buyer of the
Purchase Price will be made on the Funding Date by wire transfer of U.S. dollars in immediately available funds to the account of the Paying Agent set forth in the Election Notice (the “Paying Agent Account”), to be held by the
Paying Agent in escrow until Closing. 
 (c) The parties hereto hereby instruct Paying Agent to deliver each Seller’s Seller
Consideration to each Seller as set forth in Section 2.03 (provided that to the extent not paid previously, the exercise price in respect of any options to purchase equity securities of the Company that are exercised into
any Seller’s Seller Shares (or any portion thereof) shall be deducted from such Seller’s Seller Consideration and instead paid by the Paying Agent to the Company by wire transfer of U.S. dollars in immediately available funds). 












 Section 2.02 Closing. Upon the terms and subject to the conditions set forth in
this Agreement and the Investment Agreement, the transactions contemplated by this Agreement shall be consummated substantially contemporaneously with the consummation of the Mergers (the “Closing”). For the avoidance of doubt, the
conditions set forth in Section 3 of the Investment Agreement shall be satisfied or waived in writing prior to the Closing of the Purchase and Sale set forth in this Agreement. At the Closing: 

(a) each Seller shall (i) deliver to the Company an original share certificate(s) representing such Seller’s Seller Shares (or an
affidavit of loss or destruction in lieu thereof, in the form provided by the Company), and (ii) shall deliver to the Company, with a copy to the Buyer, a countersignature page to the Share Transfer Deed, in the form provided by the Company (a
“Transfer Deed”), duly executed by such Seller (or, to the extent applicable, the 102 Trustee) and indicating the number of Seller Shares sold by it hereunder; and 

(b) Buyer shall deliver to the Company a countersignature page to a validly executed Transfer Deed that is true and correct with respect to
each Seller, duly executed by Buyer (or, to the extent applicable, the 102 Trustee) and indicating the number of Purchased Shares purchased from such Seller by Buyer hereunder. 

Section 2.03 Paying Agent. 

(a) Wire to Paying Agent. On the Funding Date, Buyer will deposit with and delivered to the Paying Agent, by wire transfer of U.S.
dollars in immediately available funds, to the Paying Agent Account, an amount equal to the Purchase Price (the “Paying Agent Amount”). The Paying Agent Amount shall be held and distributed by the Paying Agent in accordance with the
Paying Agent Agreement and this Agreement. 
 (b) Wire to 102 Trustee. Notwithstanding anything to the contrary herein, with respect
to any 102 Securities, as indicated on Annex B hereto, the Paying Agent shall transfer immediately after the Closing, to the 102 Trustee, without any tax deduction or withholding, an amount equal to the aggregate portion of the Paying Agent
Amount payable with respect to such 102 Securities (the “102 Amount”). 
 Section 2.04 Withholding Taxes. 

(a) Each of Buyer, the Paying Agent and the 102 Trustee (each, a “Payor”), shall be entitled to deduct and withhold from the
consideration payable to each Seller in connection with the transactions contemplated by this Agreement such amounts as required to be deducted and withheld under the ITO or any other applicable tax law with respect to such Seller and in accordance
with a Valid Certificate (as defined below), if any. For the avoidance of doubt, Buyer shall not deduct or withhold any amount from the consideration transferred to the Paying Agent for the purposes of withholding tax under the ITO, or any other
provision of applicable tax law; rather, such amounts will be withheld by the Paying Agent or the 102 Trustee, as applicable, on behalf of Buyer, pursuant to the terms and conditions of the Paying Agent Agreement and the Valid Certificate. To the
extent such amounts were so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to each Seller with respect to whom such withholding or deduction was made. In the case of any amounts
withheld, the Payor shall timely remitted by the Payor to the applicable tax authority and provide to each Seller from which such amounts were withheld written confirmation of the amount so withheld. 












 (b) Notwithstanding the foregoing, in accordance with the undertaking provided by the Paying
Agent to Buyer as required under Section 6.2.4.3 of the Income Tax Circular 19/2018 (Transaction for Sale of Rights in a Corporation that includes Consideration that will be Transferred to the Seller at Future Dates), the Purchase Price payable
to each Seller hereunder who is not a holder of 102 Securities shall be retained by the Paying Agent for the benefit of each such Seller for a period of one hundred and eighty (180) days from Closing, or until an earlier date requested in
writing by the Israel Tax Authority (the “Withholding Drop Date”), during which time no payments shall be made to such Seller and the Payor(s) shall not withhold any Israeli taxes on such consideration, and each such Seller may
obtain a certification or ruling issued by the Israel Tax Authority, in form and substance reasonably acceptable to Buyer and the Paying Agent (and, upon request, Buyer and Paying Agent will be entitled to review such Seller’s application to
the Israel Tax Authority), (i) exempting the Payor from the duty to withhold Israeli taxes with respect to the applicable consideration of such Seller, (ii) determining the applicable rate of Israeli tax to be withheld from the applicable
consideration of such Seller, or (iii) providing any other instructions regarding the payment or withholding with respect to the applicable consideration of such Seller (the “Valid Certificate”). For the avoidance of doubt,
except (x) where the Seller is a current or former employee or service provider of the Company, (y) where the Seller’s Seller Shares originated from any convertible security or loan of the Company (including a SAFE) or (z) for
any transfers of payments outside of Israel, a valid certificate issued by the Israel Tax Authority pursuant to the Israeli Income Tax Regulations (Withholding from Payments for Services or Assets) 5737 – 1977 shall be deemed to be a Valid
Certificate. In the event that no later than three (3) business days prior to the Withholding Drop Date, a Seller submits a Valid Certificate, the Payor shall act in accordance with the provisions of such Valid Certificate, subject to any
deduction and withholding as may be required to be deducted and withheld under other applicable tax laws. If any Seller (A) does not provide the Payor with a Valid Certificate, by no later than three (3) business days prior to the
Withholding Drop Date, or (B) submits a written request to the Payor to release such Seller’s portion of the applicable consideration held by the Paying Agent prior to the Withholding Drop Date and fails to submit a Valid Certificate at or
before such time, then the amount to be withheld from such Seller’s consideration shall be calculated according to the applicable withholding rate, which amount shall be calculated in NIS based on a U.S. dollar to NIS exchange rate at the

possibility of total loss exists. 
 Section 3.02 Representations and Warranties of the Sellers. In connection with the
transactions contemplated by this Agreement, each Seller, severally and not jointly, with respect to itself only, hereby represents and warrants to Buyer as of the date hereof and as of the Closing as follows. 

(a) If such Seller is not an individual, such Seller has been duly formed or incorporated and is validly existing in good standing (if the
concept of good standing is applicable) under the laws of its jurisdiction of incorporation or formation, with power and authority to enter into, deliver and perform its obligations under this Agreement. If such Seller is an individual, such Seller
has the authority to enter into, deliver and perform its obligations under this Agreement. 
 (b) If such Seller is not an individual, this
Agreement has been duly authorized, validly executed and delivered by such Seller. If such Seller is an individual, the signature on this Agreement is genuine, and such Seller has legal competence and capacity to execute the same. Assuming that this
Agreement constitutes the valid and binding obligation of Buyer, is a valid and binding obligation of such Seller, and is enforceable against such Seller in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and similar laws affecting or relating to creditors’ rights generally and, subject, as to enforceability, to general principles of equity, whether such enforceability is considered in a proceeding in
equity or at law. 












 (c) The execution, delivery and performance by such Seller of this Agreement, including the
consummation of the transactions contemplated by this Agreement, will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any Lien upon
any of the property or assets of such Seller pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which such Seller is a party or by which such Seller or any of
its subsidiaries is bound or to which any of the property or assets of such Seller is subject; (ii) the organizational documents of such Seller (if applicable); or (iii) any statute or any judgment, order, rule or regulation of any court
or governmental agency or body, domestic or foreign, having jurisdiction over such Seller or any of their respective properties that, in the case of clauses (i) and (iii), would prevent, delay or otherwise impede such Seller’s timely
performance of all its obligations hereunder in full. 
 (d) There is no civil, criminal or administrative suit, action, proceeding,
arbitration, investigation, review or inquiry pending or threatened against or affecting such Seller or any of such Seller’s properties or rights that affects or would reasonably be expected to affect such Seller’s ability to consummate
the transactions contemplated by this Agreement, nor is there any decree, injunction, rule or order of any governmental authority or arbitrator outstanding against such Seller or any of such Seller’s properties or rights that affects or would
reasonably be expected to affect such Seller’s ability to consummate the transactions contemplated by this Agreement. 
 (e) Such Seller
is not obligated (and has not made any other commitments) to transfer such Seller’s Seller Shares to any other person or entity other than to Buyer pursuant to this Agreement. Such Seller is the sole record and is the beneficial owner of such
Seller’s Seller Shares (and, in the case of 102 Securities held by the 102 Trustee, is the sole beneficial owner) and has good title to such Seller’s Seller Shares, free and clear of all Liens (other than Liens arising under applicable
Securities Laws or the organizational documents of the Company, if any). 
 (f) Neither such Seller, nor any person acting on such
Seller’s behalf has, directly or indirectly, made any offers or sales of any securities of the Company or solicited any offers to buy any securities of the Company under circumstances that would require registration of the sale of such
Seller’s Seller Shares under the Securities Act or the Securities Laws (as such terms are defined in the Merger Agreement). 
 (g) Such
Seller is not insolvent, and there has been no request for, nor has there been issued, any bankruptcy decree against the Seller, whether temporary or permanent, nor has any legal, administrative or other proceeding concerning the bankruptcy of such
Seller been commenced. 
 (h) Such Seller (i) is capable of evaluating the value of such Seller’s Seller Shares and has made the
decision to sell such Seller’s Seller Shares voluntarily and without inducement by the Company or Buyer, (ii) has made his own analysis and evaluation of the transactions contemplated hereby, and (iii) has had an opportunity to
consult with legal and financial experts regarding the transactions contemplated hereby. Such Seller acknowledges that neither the Buyer, nor the Company, nor any of their personnel or agents is making or have made, and such Seller has not relied
on, any representations, warranties or agreements of Buyer (except as set forth in Section 3.01 above) or the Company, express or implied, in the decision to sell such Seller’s Seller 












 
Shares and enter into the transactions contemplated hereby. Such Seller further acknowledges that neither the Company nor the Buyer are acting as a fiduciary or financial or investment advisor to
such Seller. Neither the Buyer nor the Company, nor anyone on their behalf has any obligation or duty to provide information to such Seller relating to the value of such Seller’s Seller Shares, to the business, assets, financial condition or
prospects of the Company, or otherwise. Buyer conducted its own due diligence and analysis with respect to the Company, for its own account and purposes, all of which may provide it with a different knowledge and view of the prospects and potential,
relative to the other parties hereto and such Seller agreed to sell such Seller’s Seller Shares to the Buyer for the consideration provided for herein notwithstanding any such possible knowledge differential or any potential or prospects Buyer
or the Company may view for the Company, and waives any right, claim or demand that may arise as a result thereof. Buyer is relying on this representation in entering into this Agreement and would not do so in the absence of this representation.

 (i) Such Seller understands, acknowledges and agrees that following the Closing, such Seller shall have no rights as a shareholder of the
Company or otherwise, with respect to such Seller’s Seller Shares, including any ownership rights, participation rights in any gains, losses, profits or distributions, whether with respect to any future sale, acquisition, merger, liquidation,
dissolution or other corporate event regarding the Company or its assets, or any public offering, tender offer or other offer to purchase any of the Company’s equity securities. Such Seller further acknowledges that any such of the foregoing
events and transactions may result in the payment by the Company or a third party of assets, funds or other proceeds to the Company’s shareholders in a manner such that the value attributed to such Seller’s Seller Shares in such event or
transaction may be greater, possibly substantially, than such Seller’s Seller Consideration; and if such Seller’s Seller Shares increase in value by any means, or if the Company’s equity becomes freely tradable and increases in value,
such Seller is voluntarily forfeiting any opportunity to share in any resulting appreciation in such value. Such Seller acknowledges that such Seller has received all the information such Seller considers necessary or appropriate for deciding
whether to enter into this Agreement. 
 (j) Such Seller acknowledges that the sale of such Seller’s Seller Shares may have immediate or
future tax consequences for such Seller and confirms that any tax liability triggered as a result of the sale of such Seller’s Seller Shares and the transactions contemplated hereby (including the exercise of any options or other convertible
securities at or prior to the Closing) shall be borne solely by such Seller.

Section 4.02 Amendment; Waiver, Etc. This Agreement may not be amended, modified, waived or terminated except by an instrument in
writing, signed by the party hereto against whom enforcement of such amendment, modification, waiver, or termination is sought; provided that with respect to any such amendment, modification or waiver that (a) does not adversely affect
any Seller’s Seller Consideration or impose material additional obligations on any Seller and (b) is related to more than one Seller, then the consent of affected Sellers that hold at least sixty-six

agrees in writing to be bound by the terms hereof, including making the representations and warranties set forth in Section 3.01. Upon such assignment by Buyer, the assignee(s) shall become Buyer hereunder and have the
rights and obligations provided for herein to the extent of such assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any assignment to any fund or account managed by the
same investment manager or investment advisor as Buyer or by an affiliate of such investment manager or investment advisor, unless consented to in writing by the Company

permit the application of the laws of another jurisdiction. Any claim or cause of action based upon, arising out of or related to this Agreement or transactions contemplated by this Agreement shall be brought in the Delaware Court of Chancery, and
if the Delaware Court of Chancery does not have or take jurisdiction over such claim or cause of action,

of action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the claim or cause of action shall be heard and determined only in any such court, and
agrees not to bring any claim or cause of action arising out of or relating to this Agreement or transactions contemplated by this Agreement in any other court. Nothing herein contained shall be deemed to affect the right of any Party to serve

this Section 4.08. Each party hereto hereby consents to service of process by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at

WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

transmission or any other form of electronic delivery (including .pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or other transmission method)), all of which shall be considered one and the
same agreement and shall become effective when signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart. 

Section 4.10 Further Assurances. Subject to the terms and conditions provided herein, the parties hereto shall execute and deliver
such additional documents and take such additional actions as the parties reasonably may deem necessary in order to consummate the transactions contemplated by this Agreement. 

Section 4.11 Remedies. The parties hereto acknowledge and agree that irreparable damage would 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. It is accordingly agreed that each of the parties hereto shall be entitled to seek equitable relief, including in the form of an
injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in
tort or otherwise. The parties hereto acknowledge and agree that SPAC shall be entitled to specifically enforce the Buyer’s obligations hereunder and the provisions of this Agreement of which SPAC is a third party beneficiary, in each case, on
the terms and subject to the conditions set forth herein. Each party hereto acknowledges and agrees that the obligations, representations and covenants of each Seller hereunder are several and not joint and that no Seller shall be liable in respect
of the obligations, representations or covenants of another Seller. 












 Section 4.12 Waiver Against Trust. The parties hereto acknowledge that SPAC is a
blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving SPAC and one or more businesses or assets. The parties hereto further acknowledge that, as described
in SPAC’s prospectus relating to its initial public offering dated January 14, 2021 (the “Prospectus”) available at www.sec.gov, substantially all of SPAC’s assets consist of the cash proceeds of SPAC’s initial
public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of SPAC, its public shareholders and the underwriters of
SPAC’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to SPAC to pay its tax obligations and to fund certain of its working capital requirements, the cash in the Trust
Account may be disbursed only for the purposes set forth in the Prospectus. The parties hereto hereby irrevocably waive any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the
Trust Account, and agree not to seek recourse against the Trust Account as a result of, or arising out of, this Agreement; provided, however, that nothing in this Section 4.12 shall be deemed to limit any
party’s right, title, interest or claim to any monies held in the Trust Account by virtue of its record or beneficial ownership of shares currently outstanding on the date hereof, pursuant to a validly exercised redemption right with respect to
any such shares, except to the extent that such party has otherwise agreed with SPAC to not exercise such redemption right. 

Section 4.13 Recapitalization. Subject to the Recapitalization, if any change in the number or type of equity securities of the
Company shall occur between the date hereof and immediately prior to the Closing by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock
dividend, the number of Purchased Shares purchased by Buyer and the price per share shall be appropriately adjusted to reflect such change. 

Section 4.14 Separate and Several. For the avoidance of doubt, all obligations of the Buyer under this Agreement are separate and
several from the obligations of other purchasers that may execute separate purchase and sale agreements with the Sellers. 

Section 4.15 Termination. This Agreement shall terminate and be void and of no further force and effect, and all rights and
obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, if the Investment Agreement is terminated in accordance with its terms.
