3.2.3    There shall not be in force any order, judgment or injunction by or with any governmental
authority in the United States or Israel enjoining or prohibiting the consummation of the Subscription. 

3.2.4    The Transactions set forth in the Business Combination Agreement shall have been or will be
consummated substantially concurrently with the Closing. 
 3.3    Conditions to Closing of Subscriber.
Subscriber’s obligation to purchase the Shares at the Closing is subject to the fulfillment or (to the extent permitted by applicable law) written waiver by Subscriber, on or prior to the Closing, of each of the following conditions: 

3.3.1    The representations and warranties made by the Issuer in Section 2.2 hereof shall be true and
correct in all material respects as of the Closing (or, if such representation and warranties speak as of another date, as of such date) (other than representations and warranties that are qualified as to materiality or Issuer Material Adverse
Effect, which representations and warranties shall be so true and correct as of the Closing (or, if such representation and warranties speak as of another date, as of such date) in all respects), but, in each case, (x) without giving effect to
consummation of the Transactions and (y) other than failures to be true and correct that would not result, individually or in the aggregate, in an Issuer Material Adverse Effect. 

3.3.2    The Issuer shall have performed, satisfied and complied in all material respects with the
covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by the Issuer at or prior to the Closing, except where the failure of such performance or compliance would not or would not
reasonably be expected to prevent, materially delay, or materially impair the ability of the Issuer to consummate the Closing. 

3.3.3    There shall not be in force any order, judgment or injunction by or with any governmental
authority in the United States or Israel enjoining or prohibiting the consummation of the Subscription. 

  
 11 

 3.3.4    There shall not have occurred any suspension of
the Shares for sale or trading on the NYSE or Nasdaq and, to the Issuer’s knowledge, no proceedings for any such purpose shall have been initiated or threatened. 

3.3.5    The Transactions set forth in the Business Combination Agreement shall have been or will be
consummated concurrently with the Closing (it being understood that in the event such Transactions have not been or would not reasonably be expected to be consummated due to the assertion by the Company that any of the conditions set forth in the
Business Combination Agreement has not been or would not be satisfied, the Issuer acknowledges and agrees that the Subscriber shall not have any obligation to consummate the Closing or any liability with respect thereto; provided that, subject to
Section 5 hereof, if the Issuer and the Company subsequently consummate the Transaction, the foregoing shall no longer apply); and the terms of the Business Combination Agreement (including the conditions thereto) shall not have been amended,
and the Company shall not have waived any such term, in a manner that is materially adverse to the Subscriber (in its capacity as such). 

4.    Registration Statement. 

4.1    The Issuer agrees that, within thirty (30) calendar days after the consummation of the Transactions (the
“Filing Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement registering the resale of the Shares (the “Registration Statement”), and the Issuer
shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the
60th calendar day (or 90th calendar day if the Commission notifies the Issuer that it will “review” the Registration Statement)
following the Closing and (ii) the 10th Business Day after the date the Issuer 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 (such earlier date, the “Effectiveness Date”); provided, however, that the Issuer’s obligations to include the Shares in the Registration Statement are contingent upon Subscriber furnishing in
writing to the Issuer such information regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the Shares as shall be reasonably requested by the Issuer to effect the registration of the
Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a selling shareholder in similar situations, including providing that the Issuer 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. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the
Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section 4. For
purposes of this Section 4, the Shares included in the Registration Statement shall include, as of any date of determination, the Shares and any other equity security of the Issuer issued or issuable with respect to the
Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise. 

  
 12 

 4.2    The Issuer shall, upon reasonable request, inform Subscriber as
to the status of the registration effected by the Issuer pursuant to this Subscription Agreement. At its expense the Issuer shall: 

4.2.1    except for such times as the Issuer 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 Issuer 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 earlier of the following: (i) Subscriber ceases to hold any
Shares, (ii) the date all Shares held by Subscriber may be sold without restriction under Rule 144, including any volume and manner of sale restrictions under Rule 144 and without the requirement for the Issuer to be in compliance with the
current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) three years from the Effectiveness Date of the Registration Statement; 

4.2.2    advise Subscriber as expeditiously as possible, but in any event within five (5) Business
Days: 
 (a)    when the Registration Statement or any post-effective amendment thereto has become
effective; 
 (b)    of the issuance by the Commission of any stop order suspending the effectiveness of
the Registration Statement or the initiation of any proceedings for such purpose; and 
 (c)    of the
receipt by the Issuer of any notification with respect to the suspension of the qualification of the Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. 

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

4.2.4    upon the occurrence of any event that requires the making of any changes in the Registration
Statement or prospectus 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 light of
the circumstances under which they were made) not misleading, except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of the Registration Statement, the Issuer shall use its
commercially reasonable 

  
 13 

 
efforts to as soon as reasonably practicable prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required document so
that, as thereafter delivered to purchasers of the Shares 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; and 
 4.2.5    use its commercially reasonable
efforts to cause all Shares to be listed on each securities exchange or market, if any, on which the Issuer’s Ordinary Shares are then listed. 

4.2.6    Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer shall not have
any obligation to prepare any prospectus supplement, participate in any due diligence, execute any agreements or certificates or deliver legal opinions (other than customary de-legending certificates and
opinions or any customary Exhibit 5 opinion required in connection with the initial filing of the Registration Statement) or obtain comfort letters in connection with any sales of the Shares under the Registration Statement. 

4.3    Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer 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 the negotiation or consummation of a transaction by the
Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Issuer’s board of directors reasonably believes, upon the advice of legal counsel (which may be
in-house legal counsel), would require additional disclosure by the Issuer in the Registration Statement of material information that the Issuer 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 Issuer’s board of directors, upon the advice of legal counsel (which may be in-house legal counsel), to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided,
however, that the Issuer may not delay or suspend the Registration Statement on more than three (3) occasions, for more than sixty (60) consecutive calendar days, or more than one hundred and twenty (120) total calendar days,
in each case during any twelve (12)-month period, and there must be at least thirty (30) consecutive calendar days between any declared Suspension Events. Upon receipt of any written notice from the Issuer 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 related prospectus 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 Shares 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 Issuer 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 Issuer 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 

  
 14 

 
Issuer unless otherwise required by law or subpoena. If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the
prospectus covering the Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply (i) to the extent Subscriber is required to retain a
copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention
policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up. 

4.4    The Issuer shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold
harmless the Subscriber (to the extent a seller under the Registration Statement), the officers, directors, agents, partners, members, managers, shareholders, affiliates, employees and investment advisers of the Subscriber, each person who controls
the Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the officers, directors, partners, members, managers, shareholders, agents, affiliates, employees and investment advisers 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 costs of preparation and investigation and
reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) 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, or (ii) any
violation or alleged violation by the Issuer of the Securities Act, the Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 4, except 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 Issuer by Subscriber expressly for use therein.
Notwithstanding the forgoing, the Issuer’s indemnification obligations shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the prior written consent of the Issuer. 

The Issuer 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 4 of which the Issuer is aware. 
 4.5    Subscriber shall, severally and
not jointly with any other selling shareholder named in the Registration Statement, indemnify and hold harmless the Issuer, its directors, officers, agents and employees, each person who controls the Issuer (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
that are based upon (i) 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 

  
 15 

 
of a material fact required to be stated therein or necessary to make the statements therein (in the case 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 Issuer by Subscriber
expressly for use therein, or (ii) any violation or alleged violation by such Subscriber of the Securities Act, Exchange Act, Securities Law or any state securities law or any rule or regulation thereunder in connection with the sale of their
shares under any such Registration Statement. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Shares giving rise to such indemnification
obligation. 
 4.5.1    The indemnification provided for under this Subscription Agreement shall remain
in full force and effect regardless of any investigation made by or on behalf of the indemnified party and shall survive the transfer of the Shares purchased pursuant to this Subscription Agreement. 

4.5.2    If the indemnification provided under this Section 4.5 from the
indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses 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 or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, 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 above, 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 4.5 from any person who was not guilty of such fraudulent misrepresentation. In no event shall the liability of Subscriber be greater in amount than
the dollar amount of the net proceeds received by Subscriber upon the sale of the Shares purchased pursuant to this Subscription Agreement giving rise to such contribution obligation. 

5.    Termination. This Subscription 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 (i) such date and time as the Business Combination Agreement is validly
terminated in accordance with its terms, (ii) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (iii) if the Closing shall not have occurred on or before 30 days after the Termination
Date (as defined in the Business Combination Agreement as in effect on the date 

  
 16 

 
hereof), provided, that the right to terminate this Subscription Agreement pursuant to this clause (iii) shall not be available to the Subscriber if the Subscriber’s breach of
any of its covenants or obligations under this Subscription Agreement (or, if one or more affiliates of the Subscriber is or are, as applicable, Other Subscribers under the Other Subscription Agreements, such other Subscriber’s breach of any of
its covenants or obligations under such Other Subscription Agreement), either individually or in the aggregate, shall have resulted in the failure of the Closing or the Transactions to occur on or before the Termination Date; provided, that
(a) Section 3.1 shall survive any termination of this Agreement that occurs following the funding by Subscriber of the Purchase Price in accordance with the terms and conditions of Section 3.1, and (b) 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 breach. The Issuer shall notify
Subscriber of the termination of the Business Combination Agreement promptly after the termination of such agreement. 

6.    Miscellaneous. 

6.1    Further Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents
and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement. 

6.1.1    Subscriber acknowledges that the Issuer, the Company and the Placement Agents will rely on the
acknowledgments, understandings, agreements, representations and warranties made by Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Issuer if any of the acknowledgments,
understandings, agreements, representations and warranties made by Subscriber set forth herein are no longer accurate in all material respects. Subscriber further acknowledges and agrees that each Placement Agent is a third-party beneficiary of the
representations and warranties of the Subscriber contained in Section 2.1.8 and Section 2.1.9 of this Subscription Agreement to the extent such representations and warranties relate to such
Placement Agent. 
 6.1.2    The Issuer acknowledges and agrees that each of the Placement Agents is
entitled to rely on the agreements, representations and warranties of the Issuer contained in this Subscription Agreement. Prior to the Closing, the Issuer agrees to promptly notify the Placement Agents if any of the agreements, representations and
warranties of the Issuer are no longer accurate in all material respects. 
 6.1.3    Each of the Issuer,
Subscriber and the Company is irrevocably authorized to produce this Subscription 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. 

6.1.4    The Issuer may request from Subscriber such additional information as the Issuer may deem
necessary to evaluate the eligibility of Subscriber to acquire the Shares, and Subscriber shall promptly provide such information as may be reasonably requested, to the extent within Subscriber’s possession and control and consistent with
internal policies and procedure; provided, that, Issuer agrees to keep any such information provided by Subscriber confidential except as required by law. 

  
 17 

 6.1.5    Each party shall pay all of its own expenses in
connection with this Subscription Agreement and the transactions contemplated herein. 
 6.1.6    Each of
Subscriber and the Issuer shall take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by this Subscription Agreement on the terms and conditions
described therein no later than immediately following the consummation of the Transactions. 

6.1.7    The Subscriber hereby acknowledges and agrees that it will not, nor will any person acting at the
Subscriber’s direction or pursuant to any understanding with the Subscriber (including the Subscriber’s controlled affiliates), directly or indirectly, offer, sell, pledge, contract to sell, sell any option in, or engage in hedging
activities or execute any “short sales” (as defined in Rule 200 of Regulation SHO under the Exchange Act) with respect to, any Shares or any securities of the Company or any instrument exchangeable for or convertible into any Shares or any
securities of the Company until the consummation of the Transactions (or such earlier termination of this Subscription Agreement in accordance with its terms). Notwithstanding the foregoing, (i) nothing herein shall prohibit any entities under
common management with the Subscriber that have no knowledge of this Subscription Agreement or of the Subscriber’s participation in the transactions contemplated hereby (including the 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 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 6.1.7 shall only apply with respect to the portion of assets managed by the portfolio manager that made
the investment decision to purchase the Shares covered by this Subscription Agreement. 
 6.1.8    The
Issuer acknowledges and agrees that, notwithstanding anything herein to the contrary, the Shares may be pledged by Subscriber in connection with a bona fide margin agreement, provided such pledge shall be (i) pursuant to an available exemption
from the registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and Subscriber effecting a pledge of Shares
shall not be required to provide Issuer with any notice thereof; provided, however, that neither Issuer or their counsel shall be required to take any action (or refrain from taking any action) in connection with any such pledge, other than
providing any such lender of such margin agreement with an acknowledgment that the Shares are not subject to any contractual prohibition on pledging or lock up, the form of such acknowledgment to be subject to review and comment by Issuer in all
respects. 

  
 18 

 6.2    Notices. Any notice or communication required or permitted

so delivered personally, (ii) when sent, with no mail undeliverable or other rejection notice, if sent by email, or (iii) three (3) Business Days after the date of mailing to the address below or to such other address or addresses as such

6.3    Entire Agreement. This Subscription 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, including any commitment letter entered into relating to the subject matter hereof. 

6.4    Modifications and Amendments. This Subscription Agreement may not be amended, modified, supplemented or
waived except by an instrument in writing, signed by the party against whom enforcement of such amendment, modification, supplement or waiver is sought. 

6.5    Assignment. Neither this Subscription Agreement nor any rights, interests or obligations that may accrue to
the parties hereunder (including Subscriber’s rights to purchase the Shares) may be transferred or assigned without the prior written consent of each of the other parties hereto (other than the Shares acquired hereunder, if any, and then only
in accordance with this Subscription Agreement). Notwithstanding the foregoing, Subscriber may assign some or all of its rights and obligations under this Subscription Agreement to any fund or account managed or advised by the same investment
manager or investment adviser as the Subscriber or by an affiliate of such investment manager (which shall include any Person in which such investment manager holds 50% or more of such Person’s voting securities) without the prior consent of
the Issuer; provided that (x) prior to such assignment, any such assignee shall agree in writing to be bound by the terms hereof and (y) no such assignment shall relieve the Subscriber of its obligations hereunder. 

  
 20 

 6.6    Benefit. Except as otherwise provided herein, this
Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties,
covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns. This Subscription Agreement shall not confer rights or
remedies upon any person other than the parties hereto and their respective successors and assigns.. 

6.7    Governing Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising
out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Subscription Agreement, shall be governed by and construed
in accordance with the Laws of the State of New York, without giving effect to the principles of conflicts of law thereof. 

6.8    Consent to Jurisdiction; Waiver of Jury Trial. Each of the parties irrevocably consents to the exclusive
jurisdiction and venue of any state or federal court sitting in the Borough of Manhattan in the City and State of New York (the “Chosen Courts”), in connection with any matter based upon or arising out of this Subscription
Agreement. Each party hereby waives, and shall not assert as a defense in any legal dispute, that (i) such person is not personally subject to the jurisdiction of the Chosen Courts for any reason, (ii) such legal proceeding may not be
brought or is not maintainable in the Chosen Courts, (iii) such person’s property is exempt or immune from execution, (iv) such legal proceeding is brought in an inconvenient forum or (v) the venue of such legal proceeding is
improper. Each party hereby consents to service of process in any such proceeding in any manner permitted by New York law, further consents to service of process by nationally recognized overnight courier service guaranteeing overnight delivery, or
by registered or certified mail, return receipt requested, at its address specified pursuant to Section 6.2 and waives and covenants not to assert or plead any objection which they might otherwise have to such manner of
service of process. Notwithstanding the foregoing in this Section 6.8, a party may commence any action, claim, cause of action or suit in a court other than the Chosen Courts solely for the purpose of enforcing an order or
judgment issued by the Chosen Courts. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS
SUBSCRIPTION AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM
ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED. 

  
 21 

 6.9    Severability. If any provision of this Subscription
Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and
effect. 
 6.10    No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising
any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or
remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other
right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this
Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or
further action in any circumstances without such notice or demand. 
 6.11    Remedies. 

6.11.1    The parties agree that irreparable damage would occur if this Subscription Agreement was not
performed or the Closing is not consummated in accordance with its specific terms or was otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly agreed that the parties
hereto shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription
Agreement in an appropriate court of competent jurisdiction as set forth in Section 6.8, this being in addition to any other remedy to which any party is entitled at law or in equity, including money damages. The right
to specific enforcement shall include the right of the Issuer to cause Subscriber to cause the transactions contemplated hereby to be consummated on the terms and subject to the conditions and limitations set forth in this Subscription Agreement.
The parties hereto further agree (i) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this
Section 6.11 is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law would
be adequate.
 6.11.2    The parties acknowledge and agree that this
Section 6.11 is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement. 

6.12    Survival of Representations and Warranties. All representations and warranties made by the parties hereto
in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur immediately following the consummation of the Transactions, all representations, warranties, covenants and agreements
of the parties hereunder shall survive the consummation of the Transactions and remain in full force and effect.

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

6.14    Counterparts. This Subscription Agreement may be executed in one or more counterparts, all of which when
taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. In
the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the
same force and effect as if such signature page were an original thereof. 
 6.15    Construction. The words
“include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any
other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Subscription Agreement,” “herein,”
“hereof,” “hereby,” “hereunder,” and words of similar import refer to this Subscription Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto
intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists
another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in
breach of the first representation, warranty, or covenant. All references in this Subscription Agreement to numbers of shares, per share amounts and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock
combination, recapitalization or the like occurring after the date hereof (it being understood that the number of Shares and Purchase Price per Share set forth in this Subscription Agreement assumes that the Issuer has effected a stock split prior
to the Effective Time, on the terms contemplated by the Business Combination Agreement, in order to cause the value of each Ordinary Share to equal $10.00, and no further adjustment shall be required on account of such stock split). 

6.16    Mutual Drafting. This Subscription Agreement is the joint product of the parties hereto and each provision
hereof has been subject to the mutual consultation, negotiation and agreement of the parties and shall not be construed for or against any party hereto. 

7.    Cleansing Statement; Consent to Disclosure. 

7.1    The Company shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date
of this Subscription Agreement, issue one (1) 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 

  
 23 

 
and by the Other Subscription Agreements, and the Transactions. From and after the publication of the Disclosure Document, the Subscriber shall not be in possession of any material, non-public information received from the Company or any of its officers, directors, employees or agents in connection with the transactions contemplated by this Subscription Agreement and the Transactions, and
Subscriber shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written or oral with the Company, the Placement Agents, or any of their affiliates in connection with the Transactions;
provided, that the foregoing shall not apply to the Sponsors. 
 7.2    Subscriber hereby consents to the
disclosure in the Form 8-K filed by the Company with the SEC in connection with the execution and delivery of the Business Combination Agreement and the Proxy Statement (and, as and to the extent otherwise
required by the federal securities laws or the SEC or any other securities authorities, any other documents or communications provided by the Issuer or the Company to any governmental authority or to securityholders of the Issuer or the Company) of
Subscriber’s identity and beneficial ownership of the Shares and the nature of Subscriber’s commitments, arrangements and understandings under and relating to this Subscription Agreement and, if deemed appropriate by the Issuer or the
Company, a copy of this Subscription Agreement; provided that, in the case of such disclosures by the Issuer or the Company, the Issuer or Company, as applicable, shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure, in each case, to the extent such disclosure specifically names Subscriber. Other than in the Registration
Statement contemplated by Section 4 of this Subscription Agreement, as required by any laws, rules or regulations (including, without limitation, securities laws, rules or regulations), at the request of the staff of the Commission or any
regulatory agency or as set forth in the immediately preceding sentence, without Subscriber’s prior written consent (including by email), neither the Issuer nor the Company shall, and shall cause their respective officers, directors,
affiliates, and agents (including the Placements Agents) not to, publicly disclose the name of the Subscriber or any of its affiliates or investment advisers (i) in any press release or marketing materials or (ii) in any filing with the
Commission or any regulatory agency or trading market other than as set forth above, except to the Issuer’s securityholders, lawyers, independent accountants and other advisors and service providers who reasonably require such information in
connection with the provision of services to such person, are advised of the confidential nature of such information and are obligated to keep such information confidential. Subscriber will promptly provide any information reasonably requested by
the Issuer or the Company for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the SEC). 

8.    Trust Account Waiver. Notwithstanding anything to the contrary set forth herein, Subscriber acknowledges that
it has read the Investment Management Trust Agreement, dated as of July 13, 2020, by and between the Company and Continental Stock Transfer & Trust Company, a New York corporation, and understands that the Company has established the
trust account described therein (the “Trust Account”) for the benefit of the Company’s public shareholders and that disbursements from the Trust Account are available only in the limited circumstances set forth therein.
Subscriber further acknowledges and agrees that the Company’s sole assets consist of the cash proceeds of the Company’s initial public offering and private placements of its securities, and that substantially all of these proceeds have
been deposited in the Trust Account for the benefit of its public shareholders. Accordingly, Subscriber (on behalf of itself and its affiliates) hereby 

  
 24 

 
waives any past, present or future claim of any kind against, and any right to access, the Trust Account, any trustee of the Trust Account and the Company to collect from the Trust Account any
monies that may be owed to them by the Company or any of its affiliates for any reason whatsoever, and will not seek recourse against the Trust Account at any time for any reason whatsoever, including for any knowing and intentional material breach
by any of the parties to this Subscription Agreement of any of its representations or warranties as set forth in this Subscription Agreement, or such party’s material breach of any of its covenants or other agreements set forth in this
Subscription Agreement, which material breach constitutes, or is a consequence of, a purposeful act or failure to act by such party with the knowledge that the taking of such act or failure to take such act would cause a material breach of this
Subscription Agreement; provided, however, that nothing in this Section 8 shall be deemed to limit Subscriber’s right, title, interest, or claim to the Trust Account by virtue of Subscriber’s record or beneficial ownership of
securities of the Company acquired by any means, other than pursuant to this Subscription Agreement, including any redemption right with respect to any such securities of the Company. In the event Subscriber has any Claim against the Company under
this Subscription Agreement, Subscriber shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the property or any monies in the Trust Account. This Section 8 shall
survive the termination of this Subscription Agreement for any reason. 
 9.    Rule 144. From and after such
time as the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may allow Subscriber to sell the Shares to the public without registration are available to holders of the
Issuer’s ordinary shares and until the third (3rd) anniversary of the Closing Date, the Issuer shall, at its expense: 

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

9.2    use commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents
required of the Issuer under the Securities Act and the Exchange Act so long as the Issuer remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144 to enable
Subscriber to sell the Shares under Rule 144 for so long as the Subscriber holds any Shares; 
 9.3    furnish to
Subscriber, promptly upon Subscriber’s reasonable request, (i) a written statement by the Issuer, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act, and the Exchange Act, (ii) a copy of the
most recent annual or quarterly report of the Issuer and such other reports and documents so filed by the Issuer, and (iii) such other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144
without registration; and 
 9.4    If in the opinion of counsel to the Issuer, it is then permissible to remove the
restrictive legend from the Shares pursuant to Rule 144 under the Securities Act, then at Subscriber’s request, the Issuer will request its transfer agent to remove the legend set forth in Section 2.1.5. 

9.5    The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of
any Other Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the 

  
 25 

 
performance of the obligations of any Other Subscriber or any other investor under the Other Subscription Agreements, or the Issuer under the Business Combination Agreement. The decision of
Subscriber to purchase Shares pursuant to this Subscription 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 Issuer, the Company 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, in any Other Subscription Agreement or in the Business Combination Agreement, and no action taken by Subscriber, any investor or the Issuer pursuant hereto or thereto,
shall be deemed to constitute the Subscriber, the other investors or the Issuer as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Subscriber, the other investors or the Issuer are in any
way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement, the Other Subscription Agreements or the Business Combination Agreement. Subscriber shall be entitled to
independently protect and enforce its rights, including without limitation the rights arising out of this Subscription 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.
