Section 2.4 hereof, at any time and from time to time on or after the Prospectus Date, the Holders of at least twenty percent (20%) of the then-outstanding number of Registrable Securities (the “Demanding
Holders”) may make a written demand for Registration of 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) business 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 five (5) Registrations pursuant to a Demand Registration
under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however, that a Registration shall not be counted for such purposes unless a Form S-1 or any
similar long-form registration statement that may be available at such time (“Form S-1”) has become effective and all of the Registrable Securities requested by the Requesting Holders
to be registered on behalf of the Requesting Holders in such Form S-1 Registration have been sold, in accordance with Section 3.1 of this Agreement. 

2.1.2    Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part
of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has
been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared
effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency the
Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and 

  
 5 








 
until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a
majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly
notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration
Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated. 

2.1.3    Underwritten Offering. Subject to the provisions of subsection 2.1.4 and
Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the
offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such
Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders
proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by
the majority-in-interest of the Demanding Holders initiating the Demand Registration. 

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

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

2.2    Piggyback Registration. 

2.2.1    Piggyback Rights. If, at any time on or after the date the Company consummates a Business Combination, the
Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own
account or for the account of shareholders of the Company (or by the Company and by the shareholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement
(i) filed in connection with any employee share option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible
into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than 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.

Securities as to which registration has been requested pursuant Section 2.2 hereof, and (iii) the Ordinary Shares, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back
registration rights of other shareholders of the Company, exceeds the Maximum Number of Securities, then:

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

(C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Ordinary Shares, if any, as to which Registration has been requested pursuant to written contractual
piggy-back registration rights of other shareholders 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

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.

2.3    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”); 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

(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 

  
 9 








 
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.

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; 

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” and analyst or investor presentations and such other selling or other informational meetings organized by
the Underwriter that may be reasonably requested by the Underwriter in any Underwritten Offering, with all out-of-pocket costs and expenses incurred by the Company or
such officers in connection with such attendance and participation to be paid by the Company; 
 3.1.16    cooperate
with each Underwriter participating in the disposition of such Registrable Securities and Underwriters’ counsel in connection with any filings required to be made with The Financial Industry Regulatory Authority, Inc., including using
commercially reasonable efforts to obtain pre-clearance and pre-approval of the Registration Statement and applicable Prospectus upon filing with the Commission; 

3.1.17    within the deadlines specified by the Securities Act, make all required filing fee payments in respect of any
Registration Statement or Prospectus used under this Agreement (and any offering covered thereby); 
 3.1.18    in the
case of certificated Registrable Securities, cooperate with the Holders and the managing Underwriters to facilitate the timely preparation and delivery of certificates (not bearing any legends) representing Registrable Securities to be sold after
receiving written representations from the Holders participating in such offering that the Registrable Securities represented by the certificates so delivered by such Holders will be transferred in accordance with the Registration Statement, and
enable such Registrable Securities to be in such denominations and registered in such names as such Holders or managing Underwriters may reasonably request at least two business days prior to any sale of such Registrable Securities; and 

  
 12 








 3.1.19    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, stock powers, underwriting agreements and other customary documents as may be
reasonably required under the terms of such underwriting arrangements. 
 3.4    Suspension of Sales; Adverse
Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies
of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised
in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse
Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to
the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for
such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in
connection with any sale or offer to sell Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4. 

3.5    Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times
while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof
pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and 

  
 13 








 
complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to
enable such Holder to sell Ordinary Shares held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions.
Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE 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
members, managers, affiliates, directors, officers and agents and each person who controls such Holder (within the meaning of the Securities Act) to the fullest extent permitted by applicable law from and against all losses, claims, damages,
liabilities and expenses (including legal or other expenses reasonably incurred in connection with investigating, preparing or defending the same and the cost of enforcing any right to indemnification hereunder) to which any of them may become
subject caused by (x) any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus, disclosure package, preliminary Prospectus or free writing prospectus included in any Registration Statement, 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 or (y) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other federal law, any state or foreign securities
law, or any rule or regulation promulgated under of the foregoing laws, relating to the offer or sale of the Registrable Securities. 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, members, managers, affiliates, directors, 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 legal or other
expenses reasonably incurred in connection with investigating, preparing or defending the same and the cost of enforcing any right to indemnification hereunder) resulting from any untrue statement of material fact contained in the Registration
Statement, Prospectus, disclosure package, preliminary Prospectus or free writing prospectus included in any Registration Statement, 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


  
 14 








 
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; provided,
further that a Holder shall not be liable in any case to the extent that prior to the filing of any such Registration Statement, or any amendment thereof or supplement thereto, it has furnished in writing to the Company, information
expressly for use in, and within a reasonable period of time prior to the effectiveness of such Registration Statement, or any amendment thereof or supplement thereto which corrected or made not misleading information previously provided to the
Company. 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 or delayed). 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. 

  
 15 








 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

 5.2    Assignment; No Third
Party Beneficiaries. 
 5.2.1    This Agreement and the rights, duties and obligations of the Company hereunder may
not be assigned or delegated by the Company in whole or in part. 

  
 16 








 5.2.2    Prior to the expiration of the Founder 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 letter agreements. 
 5.2.3    This Agreement and the provisions hereof shall be binding
upon and shall inure to the benefit of each of the parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 

5.2.4    This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as
expressly set forth in this Agreement and Section 5.2 hereof. 
 5.2.5    No assignment by any
party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such assignment as provided in
Section 5.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum
or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in this Section 5.2 shall be null and void. 

5.3    Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF
counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

5.4    Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES
HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. ANY LEGAL SUIT, ACTION OR PROCEEDING ARISING
OUT OF OR BASED UPON THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY MAY BE INSTITUTED IN THE FEDERAL COURTS OF THE UNITED STATES OR THE COURTS OF THE STATE OF NEW YORK IN EACH CASE LOCATED IN THE CITY OF NEW YORK, AND EACH PARTY IRREVOCABLY
SUBMITS TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING. 
 5.5    Amendments and
Modifications. Upon the written consent of the Company and the Holders of at least fifty percent (50%) of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this
Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder,
solely in its capacity as a holder of Registrable Securities, 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. 

  
 17 








 5.6    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. 

5.7    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 (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or the
manner of sale. The provisions of Section 3.5 and Article IV shall survive any termination.
