 2.1. With Respect to Ordinary Shares and Series A Preference Shares Owned by Founders and Series A Holders: 
 (a) Security Holder Notice of Sale. If a Founder or a Series A Holder (the “Selling Security Holder”) proposes to sell or transfer any Ordinary Shares or Series A Preference Shares
held by such Selling Security Holder (the “Security Holder Transfer Shares”), then the Selling Security Holder may not sell or transfer any such Security Holder Transfer Shares unless it complies with this Section 2.1,
Section 3 and Section 4.2. The Selling Security Holder shall promptly give written notice (the “Security Holder Notice”) to the Company and to each of the other Security Holders (the “Non-Selling Security
Holders”) describing in reasonable detail the proposed sale or transfer including, without limitation, the number of Security Holder Transfer Shares, the nature of such sale or transfer, the consideration to be paid, and the name and the
address of each prospective purchaser or transferee. 

  
 6 

 (b) Notice of Purchase. Each of the Non-Selling Security Holders shall have thirty
(30) days from the date of receipt of the Security Holder Notice to agree to purchase all or any part of the Non-Selling Security Holder’s Pro Rata ROFR Share of the Security Holder Transfer Shares for the price and upon the terms and
conditions specified in the Security Holder Notice (or the actual terms of the proposed transfer, if more favorable to the proposed transferee), by giving written notice to the Selling Security Holder stating therein the number of Security Holder
Transfer Shares to be purchased (the “Security Holder Transfer Exercise Amount”). A failure by the Non-Selling Security Holder to respond within such thirty (30) day period shall be deemed to constitute a decision by such
Security Holder not to exercise its right to purchase all or any of the Security Holder Transfer Shares as provided herein. For the avoidance of doubt, each Non-Selling Security Holder may specify in its notice a Security Holder Transfer Exercise
Amount higher or lower than its Pro Rata ROFR Share of the Security Holder Transfer Shares. The Security Holder Transfer Shares shall be allocated among each Non-Selling Security Holder exercising the right of first refusal (with rounding to avoid
fractional shares) in proportion to its respective Pro Rata ROFR Share of the Security Holder Transfer Shares and on the same material terms and conditions as specified in the Security Holder Notice provided that in no event shall an amount
greater than such Non-Selling Security Holder’s Security Holder Transfer Exercise Amount be allocated to such Non-Selling Security Holder. 
 (c) Excess Security Holder Transfer Shares. Any Security Holder Transfer Shares not yet allocated to the Non-Selling Security Holders after employing the procedures set out in Section 2.1(b)
(“Excess Security Holder Transfer Shares”) shall be allocated, among all Non-Selling Security Holders exercising their right of first refusal whose Security Holder Transfer Exercise Amounts have not yet been satisfied, in proportion
to each such Non-Selling Security Holder’s respective Security Holder Transfer Excess Pro Rata ROFR Share of the Excess Security Holder Transfer Shares (with rounding to avoid fractional shares) PROVIDED THAT in no event shall a
Non-Selling Security Holder be required to purchase more Security Holder Transfer Shares pursuant to this Section 2.1(c) than the Security Holder Transfer Exercise Amount specified by such Non-Selling Security Holder in its reply notice
delivered pursuant to Section 2.1(b). The procedures set out in this Section 2.1(c) shall be repeatedly employed until the Security Holder Transfer Exercise Amounts of all Non-Selling Security Holder exercising their right of first refusal
shall have been satisfied or until the total number of the Security Holder Transfer Shares shall have been fully allocated to the Non-Selling Security Holders exercising their right of first refusal after employing the procedures set out herein,
whichever to occur first. 
 (d) Security Holder Transfer Excess Pro Rata ROFR Share. A “Security Holder
Transfer Excess Pro Rata ROFR Share” of a Non-Selling Security Holder exercising its right of first refusal equals a fraction, the numerator of which shall be such Non-Selling Security Holders’ Pro Rata ROFR Share and the denominator
of which shall be the sum of the Pro Rata ROFR Shares of all Non-Selling Security Holders exercising their right of first refusal whose Security Holder Transfer Exercise Amounts have not yet been satisfied after employing the procedures set out
herein. 
 (e) Closing. The closing of any purchase of Security Holder Transfer Shares by the Non-Selling Security
Holders shall be held at the principal office of the Company at 11:00 a.m. on the 45th day after the giving of the Security Holder Notice or at such other time and place as the parties to the transaction may agree. The said period shall be extended
if necessary to obtain any governmental approvals required for such purchase and payment. At such closing, the Selling Security Holder shall deliver certificates representing the Security Holder Transfer Shares, accompanied by duly executed
instruments of transfer (in the name of the Non-Selling Security Holders or their designated respective Affiliates). Such Security Holder Transfer Shares shall be free and clear of any encumbrance, and the Selling Security Holder shall be deemed to
so represent and warrant and shall further be deemed to represent and warrant that it is the beneficial and registered owner of such Security Holder Transfer Shares. Each Non-Selling Security Holder purchasing Security Holder Transfer Shares shall
deliver at such closing (or on such later date or dates as may be provided in the Security Holder Notice with respect to payment of consideration by the proposed transferee) payment in full of the purchase price. At such closing, all of the parties
to the transaction shall execute such additional documents as may be necessary or appropriate to effect the sale of the Security Holder Transfer Shares to the Non-Selling Security Holders. Any stamp duty or transfer taxes or fees payable on the
transfer of any Security Holder Transfer Shares shall be borne and paid equally by the Selling Security Holder and the relevant Non-Selling Security Holders. 

  
 7 

 (f) Non-Exercise. Subject to the provisions of Section 3, in the event the
Non-Selling Security Holder(s) fail to agree to purchase all of the Security Holder Transfer Shares within the respective periods given above, the Selling Security Holder shall have ninety (90) days from the date of delivery of the Security
Holder Notice to the Company and each of the Non-Selling Security Holders to sell the Security Holder Transfer Shares not so purchased at the price and upon terms and conditions no more favorable to the transferee than specified in the original
Security Holder Notice. In the event that the Selling Security Holder has not sold the Security Holder Transfer Shares within this ninety (90) day period, the Selling Security Holder shall not thereafter sell any Securities without first
offering such shares to the Non-Selling Security Holders in the manner provided in Section 2.1(a) above. 
 2.2. Right
of First Refusal With Respect to Series B Preference Shares Owned by Series B Holders and Convertible Notes owned by Note Holders. 
 (a) Holder Notice of Sale. If any Holder (the “Selling Holder”) proposes to sell or transfer any Series B Preference Shares or Convertible Notes held by such Holder (the
“Holder Transfer Securities”), then the Selling Holder may not sell or transfer any such Holder Transfer Securities unless it complies with this Section 2.2, Section 3 and Section 4.2. The Selling Holder shall
promptly give written notice (the “Holder Transfer Notice”) to the Company and the Series A Holders and the other Holders (together the “Non-Selling Holders”), describing in reasonable detail the proposed sale or
transfer including, without limitation, the amount of Holder Transfer Securities, the nature of such sale or transfer, the consideration to be paid, and the name and the address of each prospective purchaser or transferee.

(b) Reply Notice. Each Non-Selling Holder who wishes to purchase Holder Transfer Securities (an “Exercising
Holder”) shall have thirty (30) days from the date of receipt of the Holder Transfer Notice to provide the Selling Holder and the Company with a written notice (a “Reply Notice”) specifying the maximum amount of any
Holder Transfer Securities which it irrevocably commits to purchase (the “Exercise Amount”). A failure by such Non-Selling Holder to respond within such thirty (30) day period shall be deemed to constitute a decision by
such Non-Selling Holder not to exercise its right to purchase all or any of the Holder Transfer Securities as provided herein. For the avoidance of doubt, each Exercising Holder may specify in its Reply Notice an Exercise Amount higher or lower than
its Proportionate Amount (as defined below in 2.2(d)). The Holder Transfer Securities shall be allocated among each Exercising Holder (with rounding to avoid fractional shares) in proportion to its respective Proportionate Amount and on the same
material terms and conditions as specified in the Holder Transfer Notice provided that in no event shall an amount greater than such Exercising Holder’s Exercise Amount be allocated to such Exercising Holder. 

  
 8 

 (c) Excess Holder Transfer Securities. Any Holder Transfer Securities not yet
allocated to the Exercising Holders after employing the procedures set out in Section 2.2(b) (“Excess Holder Transfer Securities”) shall be allocated, among all such Exercising Holders whose Exercise Amounts have not yet been
satisfied, in proportion to each such Exercising Holder’s respective Excess Proportionate Amount (with rounding to avoid fractional shares) PROVIDED THAT in no event shall an Exercising Holder be required to purchase more Holder Transfer
Securities pursuant to this Section 2.2(c) than the Exercise Amount specified by such Exercising Holder in its Reply Notice. The procedures set out in this Section 2.2(c) shall be repeatedly employed until the Exercise Amounts of all such
Exercising Holders shall have been satisfied or until the total number of the Holder Transfer Securities shall have been fully allocated to the Exercising Holders after employing the procedures set out herein, whichever to occur first. 

(d) Proportionate Amount. An Exercising Holder’s “Proportionate Amount” is equal to the product obtainable
by multiplying (x) the total amount of Holder Transfer Securities, by (y) such Exercising Holder’s Proportionate Share. An Exercising Holder’s “Proportionate Share” shall be a fraction equal to (i) the total
number of Ordinary Shares then held by such Exercising Holder (on an as converted basis) on the date of the Holder Transfer Notice, divided by (ii) the total number of Ordinary Shares held by all Series A Holders and the Holders with the right
of first refusal with respect to the Holder Transfer Securities on the date of the Holder Transfer Notice, on an as converted basis; provided that, for purpose of this calculation only, prior to the completion of an IPO, the total number of
Ordinary Shares issuable upon conversion of all of the outstanding Convertible Notes shall be deemed to equal to 8% of all of the outstanding Securities and the number of Ordinary Shares issuable upon conversion of a Convertible Note shall be
calculated on a pro rata basis based on the principal amount. As used in this definition, the phrase “on an as converted basis” shall mean assuming conversion of all Series B Preference Shares and Convertible Notes but not assuming
exercise or conversion of Series A Preference Shares, any other outstanding option, warrants, or other convertible securities. 

(e) Excess Proportionate Amount. An Exercising Holder’s “Excess Proportionate Amount” is equal to
the product obtainable by multiplying (x) the total number of Excess Holder Transfer Securities, by (y) a fraction, the numerator of which shall be such Exercising Holder’s Proportionate Share and the denominator of which shall be the
sum of the Proportionate Shares of all Exercising Holders exercising their right of first refusal with respect to the Holder Transfer Securities whose Exercise Amounts have not yet been satisfied after employing the procedures set out herein.

 (f) Second Holder Transfer Notice. In the event the Non-Selling Holders fail to agree to purchase all of the Holder
Transfer Securities within the respective period given above, the Selling Holder shall then promptly give written notice (the “Second Holder Transfer Notice”) to each of the Founders, with a copy to the Company, setting forth the
amount of Holder Transfer Securities the Non-Selling Holders have elected not to purchase pursuant to their right of first refusal. Within ten (10) days following receipt of such Second Holder Transfer Notice, each such Founder (the
“Exercising Founder”) shall deliver a written notice to the Selling Holder, with a copy to the Company, setting forth its acceptance of the offer to purchase the remainder of the Holder Transfer Securities on a pro-rata basis;
provided, however, that all such Holder Transfer Securities purchased by any Exercising Founder that are Series B Preference Shares shall be converted into Ordinary Shares immediately prior to the transfer to the Exercising Founder.
For the purposes of this Section 2.2(f), when calculating the “pro rata” portion that a Exercising Founder may purchase from the Selling Holder if the Non-Selling Holders elect not to exercise their right of first refusal in full,
“pro rata” shall mean the number of Ordinary Shares held by the Exercising Founder as a percentage of the total number of the Ordinary Shares held by all Founders. 

  
 9 

 (g) Closing. The closing of any purchase of Holder Transfer Securities by the
Exercising Holders and the Exercising Founders shall be held at the principal office of the Company at 11:00 a.m. on the 45th day after the giving of the Holder Transfer Notice or at such other time and place as the parties to the transaction may
agree. The said period shall be extended if necessary to obtain any governmental approvals required for such purchase and payment. At such closing, the Selling Holder shall deliver certificates representing the Holder Transfer Securities,
accompanied by duly executed instruments of transfer (in the name of the Exercising Holders or the Exercising Founders or their designated respective Affiliates). Such Holder Transfer Securities shall be free and clear of any encumbrance, and the
Selling Holder shall be deemed to so represent and warrant and shall further be deemed to represent and warrant that it is the beneficial and registered owner of such Holder Transfer Securities. Each Exercising Holder or Exercising Founder
purchasing Holder Transfer Securities shall deliver at such closing (or on such later date or dates as may be provided in the Holder Notice with respect to payment of consideration by the proposed transferee) payment of the purchase price in full.
At such closing, all of the parties to the transaction shall execute such additional documents as may be necessary or appropriate to effect the sale of the Holder Transfer Securities to the Exercising Holders or the Exercising Founders. Any stamp
duty or transfer taxes or fees payable on the transfer of any Holder Transfer Securities shall be borne and paid equally by the Selling Holder, on the one hand, and the relevant Exercising Holders and the Exercising Founders, on the other hand.

 (h) Subject to the provisions of Section 3, in the event the Non-Selling Holders and/or the Founders fail to agree to
purchase all of the Holder Transfer Securities within the respective periods given above, the Selling Holder shall have ninety (90) days from the date of delivery of the Holder Transfer Notice to sell the Holder Transfer Securities not so
purchased at the price and upon terms and conditions no more favorable to the transferee than specified in the original Holder Transfer Notice. In the event that the Selling Holder has not sold the Holder Transfer Securities within this ninety
(90) day period, the Selling Holder shall not thereafter sell any Securities without first offering such shares to the Non-Selling Holders and Founders in the manner provided in this Section 2.2 above.

the outstanding Series B Preference Shares and the prior written consent of the Majority Note Holders, voting as separate classes. Each Corporate Founder shall not enter into any arrangement to issue and shall not issue any new securities of the

proposed transfer of Corporate Founder Securities by a Founder in accordance with terms of this Agreement, such transfer shall be subject to the right of first-refusal and right of co-sale set forth in this Agreement. In the event of any transfers
of any Corporate Founder Securities in violation of this Section 4.1, the Company shall have the right to repurchase up to all of the Securities of the Company owned by the applicable Corporate Founder at par value. 

  
 13 

 (b) Any transfer by any natural Person of any issued and outstanding shares (or any record
or direct or indirect beneficial ownership) in a Corporate Founder shall be exempt from the consent requirements set forth in the Subsection 4.1(a) (but will remain subject to the right of first refusal and co-sale rights of the Security Holders in

or (iii) pursuant to a court order upon the termination of a marital relationship of such transferor.

its fund manager, any person controlled by its fund manager, or to its general partner, and in case of Fidelity, transfers of its Securities to any Fidelity Persons or charitable organization, (ii) to the parents, children or spouse, siblings
or to trusts for the benefit of such persons, of such Individual Founders or employees for bona fide estate planning purposes with the prior approval of the Board, which shall not be unreasonably withheld, (iii) any transfer of Securities from
Tekventure or UIL to the Company at the repurchase price as set forth in the Ordinary Shares Purchase Agreements pursuant to the terms of the Ordinary Shares Purchase Agreements, (iv) other sale or transfer of Securities to the Company pursuant
to a repurchase right or right of first refusal held by the Company in the event of a termination of employment or consulting relationship and (v) any sale or transfer of Securities by and between employees and/or by and between Founders and an
employee, subject to the approval of the board of Directors ; PROVIDED, HOWEVER that in the case of any such transfer described herein (any such transfer shall be referred to hereinafter as a “Permitted Transfer” and
any such transferee being referred to as a “Permitted Transferee”), each Permitted Transferee shall have executed and delivered to the Company and the other Security Holders a Transfer Joinder Agreement (if such Permitted Transferee
is not already a party) as a condition precedent to any such Permitted Transfer or acquisition of the Securities. Each Security Holder hereby waives its right of first refusal, co-sale rights and any other pre-emption rights, if any, in respect of
all Permitted Transfers. For the avoidance of doubt, the requirement for the consents of the Investors contained in Section 4.1(a) shall apply to the Permitted Transfers described in this Section 4.2(iii), 4.2(v), for which
such consent shall not be unreasonably withheld. 
  

	5.	PROHIBITED TRANSFER. 

 5.1. Prohibited Transfer. In the event any party should sell any Securities in disregard or contravention of the co-sale rights under this Agreement (a “Prohibited Transfer”), the
other parties (each a “Non-Transferring Party”), in addition to such other remedies as may be available at law, in equity or hereunder, shall have the put option provided below, and such selling party (the “Transferring

expenses, incurred pursuant to the exercise or the attempted exercise of such Non-Transferring Party’s rights under Section 3 and Section 5. 
 (ii) Each Non-Transferring Party shall, if exercising the option created hereby, deliver to the Transferring Party within ninety (90) days after the later of the dates on which such Non-Transferring
Party (A) received notice of the Prohibited Transfer or (B) otherwise become aware of the Prohibited Transfer, a notice describing the type and the number of Securities to be transferred by such Non-Transferring Party. 

(iii) The Transferring Party shall, promptly upon receipt of the notice described in subsection 5.2(ii) above from the Non-Transferring
Party(ies) exercising the option created hereby, pay to each such Non-Transferring Party the aggregate purchase price for the Securities to be sold by such Non-Transferring Party, and the amount of reimbursable fees and expenses, as specified in

 (iv) Upon receipt of full payment
of the amount due from the Transferring Party, such Non-Transferring Party shall deliver to the Transferring Party the Convertible Notes, certificate or certificates representing Securities to be sold, together with a transfer form signed by such
