majority-in-interest of the then-outstanding number of Registrable Securities, or (ii) the Representative or its permitted designees (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; provided,
further, that an Underwritten Shelf Takedown shall not count as a Demand Registration. 
 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 

  
 6 













 
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 shares of Common Stock or other equity securities that the Company
desires to sell and the shares of Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders 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

Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent 

  
 7 













 
that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Common Stock 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 shares of Common Stock 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, 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 stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in
connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (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 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 

  
 8 













 
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. The notice periods set forth in this subsection 2.2.1 shall not apply to an Underwritten Shelf Takedown conducted in accordance with subsection 2.3.3. 

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a
Piggyback Registration (other than Underwritten Shelf Takedown), 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 shares of
Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, 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 shares of Common Stock, if any, as to which
Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders 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
shares of Common Stock 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 hereof, Pro Rata based on the respective number of Registrable Securities that
each Holder has so requested exercising its rights to register its Registrable Securities pursuant to subsection 2.2.1 hereof, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the
Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock, 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; 
 (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 shares of Common Stock 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 

  
 9 













 
the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock 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 shares of Common Stock 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. 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 

  
 10 













 
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. 
 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.

 2.3.3 At any time and from time to time after a Shelf has been declared effective by the
Commission, the Sponsor may request to sell all or any portion of its Registrable Securities in an underwritten offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that
the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include securities with a total offering price (including piggyback securities and before deduction of underwriting discounts) reasonably expected to
exceed, in the aggregate, $10,000,000. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company at least 48 hours prior to the public announcement of such Underwritten Shelf Takedown, which shall specify
the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. 

The Company shall include in any Underwritten Shelf Takedown the securities requested to be included by any holder (each a
“Takedown Requesting Holder”) at least 24 hours prior to the public announcement of such Underwritten Shelf Takedown pursuant to written contractual piggyback registration rights of such holder (including to those set forth
herein). The Sponsor shall have the right to select the underwriter(s) for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval which shall not be
unreasonably withheld, conditioned or delayed. For purposes of clarity, any Registration effected pursuant to this subsection 2.3.3 shall not be counted as a Registration pursuant to a Demand Registration effected under
Section 2.1 hereof. 
 2.3.4 If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in
good faith, advises the Company, the Sponsor and the Takedown Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Sponsor and the Takedown Requesting Holders (if any) desire to sell, taken
together with all other shares of Common Stock or other equity securities that the Company desires to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Underwritten Shelf Takedown, as follows: (i) first, the
Registrable Securities of the Sponsor 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 shares of
Common Stock 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 shares of Common Stock or other equity securities of the Takedown Requesting Holders, if any, that can be sold without exceeding the Maximum Number of Securities, determined Pro Rata based on the respective
number of Registrable Securities that each Takedown Requesting Holder has so requested to be included in such Underwritten Shelf Takedown. 

2.3.5 The Sponsor shall have the right to withdraw from an Underwritten Shelf Takedown for any or no reason whatsoever upon written
notification to the Company and the Underwriter or Underwriters (if any) of its intention to withdraw from such Underwritten Shelf Takedown prior to the public announcement of such Underwritten Shelf Takedown. Notwithstanding anything to the
contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with an Underwritten Shelf Takedown prior to a withdrawal under this subsection 2.3.5.

 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: 

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; 

  
 13 













 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; 

  
 14 













 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); 

  
 15 













 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 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. 

  
 16 













 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 shares of Common Stock 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. 

3.6 Limitation on Registration Rights. Notwithstanding anything herein to the contrary, (i) neither the Representative nor its
respective designees may exercise their rights under Sections 2.1 and 2.2 hereunder after five (5) and seven (7) years, respectively, after the effective date of the registration statement relating to the Company’s initial public
offering, and (ii) the Representative may not exercise its demand rights under Section 2.1 more than one time. 
 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. 
 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 

  
 17 













 
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. 

  
 18 













 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 

STOCKHOLDER RIGHTS 
 5.1
Subject to the terms and conditions of this Agreement, at any time and from time to time on or after the date that the Company consummates a Business Combination and for so long as the Sponsor holds any Registrable Securities: 

5.1.1 The Sponsor shall have the right, but not the obligation, to designate three individuals to be appointed or nominated, as the case may
be, for election to the Board (including any successor, each, a “Nominee”) by giving written notice to the Company on or before the time such information is reasonably requested by the Board or the Nominating Committee of the
Board, as applicable, for inclusion in a proxy statement for a meeting of stockholders provided to the Sponsor. 
 5.1.2 The Company will,
as promptly as practicable, use its best efforts to take all necessary and desirable actions (including, without limitation, calling special meetings of the Board and the stockholders and recommending, supporting and soliciting proxies) so that
there are three Sponsor Directors serving on the Board at all times. 

  
 19 













 5.1.3 The Company shall, to the fullest extent permitted by applicable law, use its best
efforts to take all actions necessary to ensure that: (i) each Nominee is included in the Board’s slate of nominees to the stockholders of the Company for each election of Directors; and (ii) each Nominee is included in the proxy
statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof,
and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. 

5.1.4 If a vacancy occurs because of the death, disability, disqualification, resignation, or removal of a Sponsor Director or for any other
reason, the Sponsor shall be entitled to designate such person’s successor, and the Company will, as promptly as practicable following such designation, use its best efforts to take all necessary and desirable actions, to the fullest extent
permitted by law, within its control such that such vacancy shall be filled with such successor Nominee. 
 5.1.5 If a Nominee is not
elected because of such Nominee’s death, disability, disqualification, withdrawal as a nominee or for any other reason, the Sponsor shall be entitled to designate promptly another Nominee and the Company will take all necessary and desirable
actions within its control such that the director position for which such Nominee was nominated shall not be filled pending such designation or the size of the Board shall be increased by one and such vacancy shall be filled with such successor
Nominee as promptly as practicable following such designation. 
 5.1.6 As promptly as reasonably practicable following the request of any
Sponsor Director, the Company shall enter into an indemnification agreement with such Sponsor Director, in the form entered into with the other members of the Board. The Company shall pay the reasonable, documented out-of-pocket expenses incurred by the Sponsor Director in connection with his or her services provided to or on behalf of the Company, including attending meetings or events attended explicitly on behalf of
the Company at the Company’s request. 
 5.1.7 The Company shall (i) purchase directors’ and officers’ liability
insurance in an amount determined by the Board to be reasonable and customary and (ii) for so long as a Sponsor Director serves as a Director of the Company, maintain such coverage with respect to such Sponsor Director; provided that
upon removal or resignation of such Sponsor Director for any reason, the Company shall take all actions reasonably necessary to extend such directors’ and officers’ liability insurance coverage for a period of not less than six years
from any such event in respect of any act or omission occurring at or prior to such event. 
 5.1.8 For so long as a Sponsor Director serves
as a Director of the Company, the Company shall not amend, alter or repeal any right to indemnification or exculpation covering or benefiting any Director nominated pursuant to this Agreement as and to the extent consistent with applicable law,
whether such right is contained in the Company’s amended and restated certificate of incorporation, each as amended, or another document (except to the extent such amendment or alteration permits the Company to provide broader indemnification
or exculpation rights on a retroactive basis than permitted prior thereto). 

  
 20 













 5.1.9 Each Nominee may, but does not need to qualify as “independent” pursuant to
listing standards of the New York Stock Exchange (or such other national securities exchange upon which the Company’s securities are then listed). 

5.1.10 Any Nominee will be subject to the Company’s customary due diligence process, including its review of a completed questionnaire
and a background check. Based on the foregoing, the Company may object to any Nominee provided (a) it does so in good faith, and (b) such objection is based upon any of the following: (i) such Nominee was convicted in a criminal
proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses), (ii) such Nominee was the subject of any order, judgment, or decree not subsequently reversed, suspended or vacated of any
court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice, or (B) engaging in any activity in
connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws, (iii) such Nominee was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated,
of any federal or state authority barring, suspending or otherwise limiting for more than 60 days the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such activity,
(iv) such proposed director was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission has not
been subsequently reversed, suspended or vacated, or (v) such proposed director was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree, or finding, not subsequently reversed, suspended or
vacated, relating to a violation of any federal or state securities laws or regulations. In the event the Board reasonably finds the Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (v) and reasonably objects
to the identified director, Sponsor shall be entitled to propose a different nominee to the Board within 30 calendar days of the Company’s notice to Sponsor of its objection to the Nominee and such replacement Nominee shall be subject to the
review process outlined above. 
 5.1.11 The Company shall take all necessary action to cause a Nominee chosen by the Sponsor, at the
request of such Nominee to be elected to the board of directors (or similar governing body) of each material operating subsidiary of the Company. The Nominee, as applicable, shall have the right to attend (in person or remotely) any meetings of the
board of directors (or similar governing body or committee thereof) of each subsidiary of the Company.

 6.8 Amendments and Modifications. Upon the written consent of the Company and the Holders of
at least a majority-in-interest of the Registrable Securities (which consent must include the Representative if such amendment or modification is material and adverse to
the Representative) 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 stock 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

other rights or remedies hereunder or thereunder by such party.

 6.10 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. 
 6.11 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
