subsection 2.1.4 and Section 2.4 hereof, at any time and from time to time on or after the date the Company consummates the Business Combination, any Holder that together with its affiliates owns at least 20% in
interest of the then-outstanding number of Registrable Securities (the “Demanding Holder”) may make a written demand for Registration of all or part of its 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 ten (10) 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 five (5) 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 Holder and Requesting Holders pursuant to such Demand Registration. Under no
circumstances shall the Company be obligated to effect more than two (2) Registrations per eligible Holder pursuant to a Demand Registration under this subsection 2.1.1; 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) the Demanding Holder initiating such Demand Registration thereafter affirmatively elects within five (5) days to continue with such Registration and
accordingly notifies the Company in writing of such election within such five (5) day-period; 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 the Demanding Holder so advises the Company as part of its 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 Demanding Holder 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 Holder and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holder and the Requesting Holders (if
any) desire to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell and the 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 Holder 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 that the Demanding Holder and Requesting Holders have requested be 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 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 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. The Demanding Holder 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 ten (10) 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 five (5) 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 shares of Common Stock that the Company desires
to sell, taken together with (i) the 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 to Section 2.2 hereof, and (iii) the 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 Common Stock or other equity securities that the Company desires to sell, 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 hereof, Pro Rata, 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 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 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 the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the 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 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 Registrations on Form S-3. 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 any 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; provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within five (5) days of the Company’s receipt of a written request from a
Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on
Form S-3 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 on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not
more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on Form S-3, 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 Section 2.3 if (i) a Form S-3 is not available for such offering; or
(ii) 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. In the event the Company files a registration statement pursuant to this Section 2.3 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.

 2.4 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.

date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or
sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and
as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders; 

3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing Underwriter of such offering; 
 3.1.14 make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50,000,000, use its
reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in any Underwritten Offering; and 

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in
connection with such Registration. 
 3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by
the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter
marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders. 











 3.3 Requirements for Participation in Underwritten Offerings. No person may
participate in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in 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.
 3.4.1 The Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement for a
reasonable period of time, not to exceed 90 calendar days in any 360-day period (i) during any customary blackout or similar period or as permitted hereunder and (ii) as may be necessary in
connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of the Issuer’s Annual Report on Form 10-K for its first completed fiscal year.

 3.4.2 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 he, she or 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 he, she or 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 shares of the 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), including providing any legal
opinions, to the extent such exemption is available to Holders at such time. 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 IV 

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

 4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and
(ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim
with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall
not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No
indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying
party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or
litigation. 
 4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities
participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

 4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is
unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to
the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well
as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by 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 V 

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 or the future holders of the Founder Shares (or the
securities into which the Founder Shares convert), as applicable, holds any Registrable Securities: 
 5.1.1 The Sponsor and the future
holders of the Founder Shares (or the securities into which the Founder Shares convert) held by the Sponsor as of the date hereof shall have the right, but not the obligation, to designate (a) three (3) individuals, for so long as such persons
continue to hold, collectively, at least 50% of the Founder Shares (or the securities into which the Founder Shares convert) held by the Sponsor as of the date hereof, (b) two (2) individuals, for so long as such persons continue to hold,
collectively, at least 30% of the Founder Shares (or the securities into which the Founder Shares convert) held by the Sponsor as of the date hereof, and (c) one (1) individual, for so long as such persons continue to hold, collectively, at
least 20% of the Founder Shares (or the securities into which the Founder Shares convert) held by the Sponsor as of the date hereof, in each case, 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 and Corporate Governance Committee of the Board, as applicable, for
inclusion in a proxy statement for a meeting of stockholders. 
 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 the applicable number of Sponsor Directors is serving on
the Board at all times during which the nomination rights provided in Section 5.1.1 are applicable. 
 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 during the period in which rights provided in Section 5.1.1 are applicable, the Sponsor or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as the case may be, 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 or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as the case may be, 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. 

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 certificate of incorporation or bylaws, 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). 
 5.1.9 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, the Sponsor or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as applicable, shall be entitled to propose a different
nominee to the Board within 30 calendar days of the Company’s notice to Sponsor or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as applicable, of its objection to the Nominee and such
replacement Nominee shall be subject to the review process outlined above. 
 5.1.10 The Company shall take all necessary action to cause a
Sponsor Director chosen by the Sponsor or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as the case may be, to be elected to the board of directors (or similar governing body) of each material
operating subsidiary of the Company to the extent requested by the Sponsor or the future holders of the Founder Shares (or the securities into which the Founder Shares convert), as applicable. Such Sponsor Director 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.

or in part. 
 6.2.2 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 and other applicable agreements. 

6.2.3 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. 
 6.2.4 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 6.2 hereof. 

6.2.5 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 6.1 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 6.2 shall be null and void. 
 6.3 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. 

6.4 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. A signed copy of this Agreement delivered by facsimile, e-mail or other

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. 
 6.6 Governing Law;
Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS

AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK. 
 6.7 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. 
 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 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 his, her or its capacity as a holder of the shares of capital 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 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. 
 6.9 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. 
 6.10 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. 
 6.11 Other Registration
Rights. The Company represents and warrants that no person, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company
in any Registration filed by the Company for the sale of securities for its own account or for the account of any other person. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement
or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. 











 6.12 Term. This Agreement shall terminate upon the earlier of (i) the tenth
anniversary of the date of this Agreement or (ii) the date as of which (A) all of the Registrable Securities have been sold pursuant to a Registration Statement (but in no event prior to the applicable period referred to in
Section 4(a)(3) of the Securities Act and Rule 174 thereunder (or any successor rule promulgated thereafter by the Commission)) or (B) the Holders of all of the Registrable Securities are permitted to sell the Registrable
