Securities (the “Demanding Holders”) may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe the
amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within five (5) days of the
Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s
Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so
notify the Company, in writing, within three (3) business days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such
Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days
immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the
Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however, that a
Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration statement that may be available at such time (“Form
S-1”) has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Form S-1 Registration have been sold, in accordance with Section 3.1 of this Agreement. 

2.1.2     Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this
Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been
declared effective by the Commission and (ii) the Company has complied with all of its obligations 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 initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the
Company in writing, but in no event later than five (5) days, of such election; provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that
has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is 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 offering of the Registrable Securities pursuant to such
Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s
participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an
Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

 2.1.4     Reduction of Underwritten Offering. If the managing Underwriter or
Underwriters in an Underwritten Registration pursuant to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that
the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Ordinary Shares or other equity securities that the Company desires to sell and the Ordinary Shares, if any, as to which a Registration has been
requested pursuant to separate written contractual piggy-back registration rights held by any other shareholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten
Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the
“Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata
based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities of the Demanding
Holders and Requesting Holders that are included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of
Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Ordinary Shares or other equity securities of other persons or entities that the Company is
obligated to register in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities. 

2.1.5     Demand Registration Withdrawal. A
majority-in-interest of the Demanding Holders initiating a Demand Registration or a
majority-in-interest of the Requesting Holders (if any), pursuant to a Registration under subsection 2.1.1 shall have the right to withdraw from a Registration
pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the
Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration. Notwithstanding anything to the contrary in this Agreement, (i) the Company may effect any
Underwritten Registration pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering and (ii) the Company shall be responsible for the
Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5. 

2.2     Piggyback Registration. 

2.2.1     Piggyback Rights. If, at any time on or after the date the Company consummates a Business Combination, the Company
proposes to file a 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 or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than seven (7) days before the
anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of 

  
 6 













 
distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to
register the sale of such number of Registrable Securities as such Holders may request in writing within three (3) business days after receipt of such written notice (such Registration a “Piggyback Registration”). The
Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the
Registrable Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit
the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this
subsection 2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company. 

2.2.2     Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is
to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of the Ordinary Shares that the Company desires to
sell, taken together with (i) the Ordinary Shares, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder,
(ii) the Registrable Securities as to which registration has been requested pursuant Section 2.2 hereof, and (iii) the Ordinary Shares, if any, as to which Registration has been requested pursuant to separate written
contractual piggy-back registration rights of other shareholders of the Company, exceeds the Maximum Number of Securities, then: 

(a)     If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration
(A) first, the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (B) second, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1, Pro Rata, which can be sold without exceeding the Maximum Number
of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Ordinary Shares, if any, as to which Registration has been requested pursuant to written
contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached
under the foregoing clauses (A), (B) and (C), the Ordinary Shares or other equity securities that the Company desires to sell; 

(b)     If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the
Company shall include in any such Registration (A) first, the Ordinary Shares or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the
Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable
Securities pursuant to subsection 2.2.1, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses
(A) and (B), the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clauses (A), (B) and (C), the Ordinary Shares or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements
with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

 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.

(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; 

  
 10 













 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; 

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. 

  
 11 













 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 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 

  
 12 













 
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.

 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. 

  
 13 













 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 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

whole or in part. 

  
 14 













 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. 
 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.  

  
 15 













 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 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.
