standing under the Laws of the jurisdiction of its organization, and (B) has all 

  
 4

Stockholder’s spouse or domestic partner (if such Stockholder is a natural person and has a spouse or domestic partner, as applicable), (ii) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of
termination) of or a default under, the loss of any benefit under, the creation, modification or acceleration of any obligations under or the creation of a Lien on any of the properties, rights or assets of such Stockholder pursuant to any Contract
binding upon such Stockholder or, assuming (solely with respect to performance of this Agreement and the transactions contemplated hereby), compliance with the matters referred to in Section 4(d), under any applicable Law to which such
Stockholder is subject, (iii) any change in the rights or obligations of any party under any Contract legally binding upon such Stockholder or (iv) any violation of applicable Law, except, in the case of clauses (ii), (iii) or
(iv) directly above, for any such breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay or impair such
Stockholder’s ability to perform its obligations hereunder or to consummate the transactions contemplated hereby or the Transactions.

 15. Governing Law and Venue; Service of Process; Waiver of Jury Trial. 

(a) This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions
contemplated hereby, shall be governed by, and construed in accordance with, the internal Laws of the State of Delaware, including its statute of limitations, without giving effect to principles or rules of conflict of laws to the extent such

 (b) Any Action
based upon, arising out of or related to this Agreement or the transactions contemplated hereby may only be brought in the Court of Chancery of the State of Delaware or, if such court lacks jurisdiction, the state and federal courts in the State of
Delaware, and each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such 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 Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any other court. Nothing herein
contained shall be deemed to affect the right of any Party to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other Party in any other jurisdiction, in each case, to enforce judgments

and void. This Agreement shall be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns. 

  
 12 

 17. Enforcement. The Parties agree that irreparable damage (for which monetary
damages, even if available, would not be an adequate remedy) would occur, and that the Parties would not have any adequate remedy at law, 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 the Parties shall be entitled to specific performance, an injunction or injunctions, or other equitable relief to prevent breaches or threatened breaches of this Agreement and to
enforce specifically the terms and provisions of this Agreement, including each Stockholder’s obligations under Section 1, without proof of actual damages or otherwise (and each Party hereby waives any requirement for the securing or
posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at Law or in equity. Each Party acknowledges and agrees that the right of specific enforcement is an integral part of the
transactions contemplated hereby and that, without such right, none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that
the other Parties have an adequate remedy at Law. 
 18. Severability. If any term or other provision of this Agreement is held by a
court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the
transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is
subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to have been declared effective,
unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated and (ii) a majority-in-interest of the Demanding Holders

subsequently terminated. 
 2.1.3 Underwritten Offering. Subject to the provisions of subsection 2.1.4 and
Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the

Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of
shareholders of the Company (or by the Company and by the shareholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in connection with any
employee share option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible into equity securities of the Company

 2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to
withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the
effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration (or in the case of an Underwritten Registration pursuant to Rule 415 under the Securities Act, at least two business days prior to the
time of pricing of the applicable offering). The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement
filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the
Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3. 

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2
hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof. 
 2.3 Shelf
Registrations. 
 2.3.1 The Holders of Registrable Securities may at any time, and from time to time, request in writing that the Company, pursuant to
Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or similar short form
registration statement that may be available at such time (“Form S-3”), or if the Company is ineligible to use Form S-3, on Form S-1; a registration statement filed pursuant to this subsection 2.3.1 (a “Shelf”) shall provide for the resale of the Registrable Securities included therein
pursuant to any method or combination of methods legally available to, and requested by, any Holder. Within three (3) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration
on a Shelf, the Company shall promptly give written notice of the proposed Registration to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s
Registrable Securities in such Registration shall so notify the Company, in writing, within three (3) business days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than ten
(10) days after the Company’s initial receipt of such written request for a Registration on a Shelf, the Company shall register all or such portion of such Holder’s Registrable Securities as are specified in such written request,
together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided, however, that the Company shall
not be obligated to effect any such Registration pursuant to this subsection 2.3.1 if the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in
such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $10,000,000. The Company shall maintain each Shelf in accordance with the terms hereof, and
shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep such Shelf continuously effective, available for use and in compliance with
the provisions of the Securities Act until such time as there are no longer any Registrable Securities included on such Shelf. In the event the Company files a Shelf on Form S-1, the Company shall use its
commercially reasonable efforts to convert the Form S-1 to a Form S-3 as soon as practicable after the Company is eligible to use Form
S-3. 

  
 8 

 2.3.2 If any Shelf ceases to be effective under the Securities Act for any reason at any time while
Registrable Securities included thereon are still outstanding, the Company shall use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including
obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the
withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities including on such Shelf,
and pursuant to any method or combination of methods legally available to, and requested by, any Holder. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf
Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the
provisions of the Securities Act until such time as there are no longer any Registrable Securities included thereon. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company
is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the
Company, upon request of a Holder shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, a Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the
terms hereof; provided, however, the Company shall only be required to cause such Registrable Securities to be so covered once annually after inquiry of the Holders. 

2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good
faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to
receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the
Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be
seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the
Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such
Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more
than once in any 12-month period. Notwithstanding anything to the contrary contained in this Agreement, no Registration shall be effected or permitted and no Registration Statement shall become effective, with
respect to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the
case may be. 
 ARTICLE 3 

COMPANY PROCEDURES 
 3.1 General
Procedures. If at any time on or after the date the Company consummates a Business Combination the Company is required to effect the Registration of Registrable Securities, the Company shall use its best efforts to effect such Registration to
permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible: 

  
 9 

 3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to
such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities covered by such Registration Statement have been sold; 

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration
Statement, and such supplements to the Prospectus, as may be requested by the Holders or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by the
Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution
set forth in such Registration Statement or supplement to the Prospectus; 
 3.1.3 prior to filing a Registration Statement or Prospectus, or any amendment
or supplement thereto, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies of such Registration Statement as proposed to be filed,
each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary
Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable
Securities owned by such Holders; 
 3.1.4 prior to any public offering of Registrable Securities, use its best efforts to (i) register or qualify the
Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of
their intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be
necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or
take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject; 

3.1.5 cause all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued by the
Company are then listed; 
 3.1.6 provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than
the effective date of such Registration Statement; 
 3.1.7 advise each seller of such Registrable Securities, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its reasonable best
efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 
 3.1.8 at least five (5) days
prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (other than by way of a document incorporated by reference) furnish a copy thereof to each seller of such
Registrable Securities or its counsel; 

  
 10 

 3.1.9 notify the Holders at any time when a Prospectus relating to such Registration Statement is required
to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in
Section 3.4 hereof; 
 3.1.10 permit a representative of the Holders, the Underwriters, if any, and any attorney or accountant
retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably
requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriters enter into a confidentiality agreement, in form and substance
reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 
 3.1.11 obtain a “cold comfort” letter from
the Company’s independent registered public accountants in the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter
may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 

3.1.12 on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel
representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such
opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the
participating Holders; 
 3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing Underwriter of such offering; 
 3.1.14 make available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 
 3.1.15 if the
Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50,000,000, use its reasonable efforts to make available senior executives of the Company to participate in customary “road show”
presentations that may be reasonably requested by the Underwriter in any Underwritten Offering; and 
 3.1.16 otherwise, in good faith, cooperate reasonably
with, and take such customary actions as may reasonably be requested by the Holders, in connection with such Registration. 
 3.2 Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as
Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel
representing the Holders. 
 3.3 Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for
equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in 

  
 11 

 
any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities,
lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. 

3.4 Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a
Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby
covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or
continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable
to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the
shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to
suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities. The Company shall immediately notify the Holders
of the expiration of any period during which it exercised its rights under this Section 3.4. 
 3.5 Reporting Obligations.
As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further
covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Ordinary Shares held by such Holder without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission, to the extent that such rule or such successor rule is available to the Company),
including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE 4 
 INDEMNIFICATION
AND CONTRIBUTION 
 4.1 Indemnification. 
 4.1.1 The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto
or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the
Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in
the foregoing with respect to the indemnification of the Holder. 

  
 12 

 4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is
participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall
indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable
attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein;
provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and
limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person
who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 

4.1.3 Any person entitled to indemnification herein shall (i) 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 right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) 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 consent shall not be
unreasonably withheld). 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 for all parties indemnified by such indemnifying party
with respect to such claim, unless in the reasonable judgment of 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, 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 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. 

4.1.4 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 or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such
provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason. 

4.1.5 If the indemnification provided under Section 4.1 hereof 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 

  
 13 

 
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; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such
liability. 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 subsections 4.1.1, 4.1.2 and
4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this
subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. 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 subsection 4.1.5 from any person who was not guilty of such
fraudulent misrepresentation. 
 ARTICLE 5

 5.2 Assignment;
No Third Party Beneficiaries. 
 5.2.1 This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated
by the Company in whole or in part. 
 5.2.2 Prior to the expiration of the Founder Shares Lock-up Period or the
Private Placement Lock-up Period, as the case may be, no Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a
transfer of Registrable Securities by such Holder to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement, the Warrant Agreement or any other applicable letter
agreements between the Company and such Holder. 

  
 14 

 5.2.3 This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each
of the parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 
 5.2.4 This Agreement shall not
confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in this Agreement and Section 5.2 hereof. 

5.2.5 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and
until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be
bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in this Section 5.2 shall be
null and void. 
 5.3 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof
shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of
this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable. 
 5.4
Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which
need be produced. 
 5.5 Entire Agreement. This Agreement (including all agreements entered into pursuant hereto and all certificates and instruments
delivered pursuant hereto and thereto) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior and contemporaneous agreements, representations, understandings, negotiations and discussions
between the parties, whether oral or written. 
 5.6 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF
THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW
YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. 
 5.7 WAIVER OF TRIAL BY JURY. EACH PARTY HEREBY IRREVOCABLY
AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREBY, OR THE ACTIONS OF THE SPONSOR IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF. 
 5.8 Amendments and Modifications.
Upon the written consent of the Company and the Holders of at least a majority in interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be
waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its
capacity as a holder of the shares of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course 

  
 15 

 
of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement
shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or
remedies hereunder or thereunder by such party. 
 5.9 Titles and Headings. Titles and headings of sections of this Agreement are for
convenience only and shall not affect the construction of any provision of this Agreement. 
 5.10 Waivers and Extensions. Any party to this
Agreement may waive any right, breach or default which such party has the right to waive, provided that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this
Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a
waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for
performance of any other obligations or acts. 
 5.11 Remedies Cumulative. In the event that the Company fails to observe or perform any covenant or
agreement to be observed or performed under this Agreement, the Holders may proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an injunction
against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the
rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or now or
hereafter available at law, in equity, by statute or otherwise. 
 5.12 Term. This Agreement shall terminate upon the earlier of (i) the tenth
anniversary of the date of this Agreement and (ii) the date as of which no Registrable Securities remain outstanding. The provisions of Section 3.5 and Article V shall survive any termination.
