its Shares, the Seller shall deliver to the Company and the Eligible Investors a written notice (the “Transfer Notice”) stating: (i) the Seller’s bona fide intention to sell or otherwise Transfer such Shares (such Shares,
the “Offered Shares”); (ii) the name, address and phone number of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the aggregate number of Offered Shares to be Transferred to each
Proposed Transferee; (iv) the bona fide cash price or other consideration for which the Seller proposes to Transfer the Offered Shares (the “Offered Price”) and the other material terms of such proposed Transfer; (v) each

Company and Eligible Investors must exercise such rights. 
 3. Right of First Refusal. 

(a) Exercise by the Company. The Company has a Right of First Refusal to purchase all or any part of the Offered Shares, provided
that the Company gives written notice of the exercise of such right to the Seller within thirty (30) days (the “Initial Refusal Period”) after the last date on which the Transfer Notice is, pursuant to Section 9(a) hereof,
deemed to be effective as to the Company and all Eligible Investors. 
 (b) Initial Exercise by the ROFR Eligible
Investors. Subject to the limitations of this Section 3(b), concurrently with the Company, the ROFR Eligible Investors and their affiliated assignees (any affiliate, partner, retired partner, member, retired member, family member, or trust,
either with respect to a particular exercise of rights or as a transferee of Shares previously held by a ROFR Eligible Investor) have a Right of First Refusal to purchase all or any part of the Offered Shares; provided that each ROFR Eligible
Investor so electing gives written notice of the exercise of such right to the Seller within the Initial Refusal Period. Such notice by each ROFR Eligible Investor shall state the maximum number of Offered Shares such ROFR Eligible Investor commits
to purchase pursuant to the terms of this Section 3. Upon the earlier to occur of (i) the termination of the Initial Refusal Period or (ii) the time when the Seller has received written confirmation from the Company regarding its
exercise of its Right First Refusal, the Company shall be deemed to have made its election with respect to the Offered Shares, and the shares for which the ROFR Eligible Investors may exercise their Rights of First Refusal shall be correspondingly
reduced to the extent the Company elects to purchase all or any part of the Offered Shares. To the extent that the Company elects not to purchase all of the Offered Shares, such remaining shares shall be allocated to the ROFR Eligible Investors (the
“Remaining Shares”) who have given written notice of their exercise of such right within the Initial Refusal Period (the “Participating Investors”). To the extent that the aggregate number of shares that the
Participating Investors desire to purchase exceeds the Remaining Shares, each Participating Investor will be entitled to purchase its Pro Rata ROFR Share of the Remaining Shares. Any Remaining Shares not allocated to Participating Investors pursuant
to the immediately preceding sentence shall be reallocated to those Participating Investors who fully exercised their Right of First Refusal (“Fully Exercising Investors”). Such reallocation among Fully Exercising Investors shall be
on the same basis as the initial allocation, excluding from the denominator for each relevant calculation Participating Investors who are not Fully Exercising Investors. Within five (5) days after the expiration of the Initial Refusal Period,
the Seller will give written notice to the Company and each ROFR Eligible Investor specifying the number of Offered Shares that was subscribed by the Company and the Participating Investors (the “Confirmation Notice”). The
Confirmation Notice shall specify the number of shares to be purchased by the Company and the Participating Investors. It shall also specify the number of shares not purchased, if any, under Sections 3(a) and 3(b) hereof. 

  
 -4-









 (c) Purchase Price. The purchase price for the Offered Shares to be purchased by the
Company or by a Participating Investor under this Agreement will be the Offered Price, and will be payable as set forth in Section 3(d) hereof. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration will be determined by the Board of Directors of the Company in good faith, which determination will be binding upon the Company, each Participating Investor and the Seller, absent fraud or error. All other material terms of
such sale will be those set forth in the Transfer Notice. 
 (d) Payment. Payment of the purchase price for the Offered
Shares purchased by the Company or by a Participating Investor will be made within fifteen (15) days after the delivery of the Confirmation Notice. Payment of the purchase price will be made, at the option of the Company or the Participating
Investor, (i) in cash (or by check), (ii) by cancellation of all or a portion of any outstanding indebtedness of the Seller to the Company or the Participating Investor, as the case may be, or (iii) by any combination of the
foregoing. 
 (e) Rights as a Member. If the Company or any ROFR Eligible Investor exercises its Right of First Refusal
to purchase all or any part of the Offered Shares, then, upon the date that the notice of such exercise by the Company or any ROFR Eligible Investor is deemed to be effective as to the Seller pursuant to Section 9(a) hereof (the
“Transfer Date”), the Seller will have no further rights as a holder with respect to such Offered Shares except the right to receive payment for such Offered Shares from the Company or the ROFR Eligible Investor(s), as the case may
be, in accordance with the terms of this Agreement. The Seller will forthwith cause all certificate(s) evidencing such Offered Shares to be surrendered for transfer to the Company or the ROFR Eligible Investor, as the case may be, and in the case of
a Transfer of Offered Shares to a ROFR Eligible Investor, upon payment of the purchase price for such shares by such ROFR Eligible Investor, the Company will register such ROFR Eligible Investor in the Company’s register of members as the
holder with respect to such Offered Shares. Following the Transfer Date, and until such time as the Company registers the ROFR Eligible Investor in the Company’s register of members in accordance with the preceding sentence, the Seller shall
vote its Offered Shares which such ROFR Eligible Investor is exercising its right to purchase as directed by such ROFR Eligible Investor and hold any dividends or other distributions on such Offered Shares received after the Transfer Date for the
benefit of such ROFR Eligible Investor to be paid to such ROFR Eligible Investor upon payment by ROFR Eligible Investor of the purchase price for such Offered Shares. 
 (f) Sellers’ Right to Transfer. If the Company and the ROFR Eligible Investors have not elected to purchase all or any portion of the Offered Shares, then the Seller may Transfer such portion
of the Offered Shares which the Company and, if applicable, the ROFR Eligible Investors have not elected to purchase to any Proposed Transferee named in the Transfer Notice, at the Offered Price or at a higher price; provided that such
Transfer shall still be subject to the Co-Sale Eligible Investors’ Right of Co-Sale as defined in Section 4 hereof and the Seller shall not enter into a binding agreement to sell any Offered Shares until all of the provisions of
Section 4(a) have been complied with; provided further that any such Transfer (i) is consummated within ninety (90) days after the end of the Initial Refusal Period, (ii) is on terms no more favorable to the Proposed


  
 -5-









 
Transferee than the terms proposed in the Transfer Notice, and (iii) is in accordance with all the terms of this Agreement. If the Offered Shares are not so Transferred during such ninety
(90) day period, then the Seller may not Transfer any of such Offered Shares without complying again in full with the provisions of this Section 3. 
 4. Right of Co-Sale. 
 (a) Initial Exercise by the Eligible
Investors. To the extent that the Company and the ROFR Eligible Investors do not exercise their respective Rights of First Refusal in full with respect to all of the Offered Shares pursuant to Section 3 hereof (i.e., Seller has a right to
transfer pursuant to Section 3(f)), then the Seller shall not enter into a binding agreement to sell any Offered Shares until all of the provisions of this Section 4(a) have been complied with. Each Eligible Investor who has not exercised
its right in Section 3(b) (a “Co-Sale Investor”) that notifies Seller in writing within seven (7) days after the delivery of the Confirmation Notice, as applicable (the “Initial Co-Sale Period”),
shall have the right to participate in such sale of shares (the “Co-Sale Eligible Shares”) on the same terms and conditions as specified in the Transfer Notice subject to the terms of this Section 4. Each Co-Sale Investor who
delivers a notice pursuant to the preceding sentence (a “Selling Investor”) may sell, pursuant to the Selling Investor’s Right of Co-Sale, up to that number of Shares held by such Selling Investor equal to the product of the
Co-Sale Eligible Shares multiplied by such Selling Investor’s Pro Rata Share. The Selling Investor shall indicate the number of Shares it then holds that it wishes to sell pursuant to this Section 4(a) (the “Selling Investor
Shares”). If, after the end of the Initial Co-Sale Period, any Co-Sale Investors decline to participate in sales under this Section 4 or do not fully exercise their full Right of Co-Sale, then, within two (2) days after the
Initial Co-Sale Period, the Seller will notify the Selling Investors who fully exercised their Right of Co-Sale pursuant to this Section 4(a) (“Fully Exercising Co-Sale Investors”) of the extent to which other Co-Sale Investors
declined to exercise their Right of Co-Sale (the “Co-Sale Notice”). The Fully Exercising Co-Sale Investors shall within five (5) days after the later of (i) the end of the Initial Co-Sale Period and (ii) the delivery
of the Co-Sale Notice as deemed to be effective in accordance with Section 9(a) hereof (the “Subsequent Co-Sale Period”), notify Seller of the number of additional Shares held by such Fully Exercising Co-Sale Investor that such
Selling Investor wishes to sell. If such requests are over-subscribed, the Fully Exercising Co-Sale Investors shall be cut back, pro rata, based on the Shares held (on an as-converted basis). The sale of the Selling Investor Shares shall
occur within twenty-five (25) days from the beginning of the Initial Co-Sale Period (the “Closing”). This Right of Co-Sale shall not apply with respect to Offered Shares sold or to be sold to ROFR Eligible Investors or the
Company under the Right of First Refusal. 
 (b) Consummation of Co-Sale. A Selling Investor may exercise the Right of
Co-Sale by delivering to the Seller at or before the Closing, one or more certificates, properly endorsed for Transfer, representing a number of shares not to exceed the number of shares to which Selling Investor is entitled in Section 4(a),
representing such Shares to be Transferred by the Seller on behalf of the Selling Investor. If the Selling Investor does not hold a certificate in that series, class or type of shares representing the number of securities owned and to be sold by
such Selling Investor pursuant to this Section 4, then the Company shall promptly issue a certificate representing the proper number of shares to be sold pursuant to this Right of Co-Sale. Following the Closing, the Company shall deliver a
certificate for the remaining balance of the securities held by the Selling Investor, if any, to such Selling Investor. At the Closing, such certificates or other instruments will 

  
 -6-









 
be transferred and delivered to the Transferee as set forth in the Transfer Notice in consummation of the Transfer of the Offered Shares pursuant to the terms and conditions specified in the
Transfer Notice, and the Seller will remit, or will cause to be remitted, to each Selling Investor, within ten (10) days after such Closing, that portion of the proceeds of the Transfer to which each Selling Investor is entitled by reason of
each Selling Investor’s participation in such Transfer pursuant to the Right of Co-Sale. 
 5. Multiple Series, Class
or Type of Shares. If the Offered Shares consists of more than one series, class or type of Shares, the Seller has the right to Transfer hereunder each such series, class or type; provided that if, as to the Right of Co-Sale, a
Selling Investor does not hold any of such series, class or type, and the Proposed Transferee is not willing, at the Closing, to purchase some other series, class or type of Shares from such Selling Investor, or is unwilling to purchase any Shares
from such Selling Investor at the Closing, then such Selling Investor will have the put right (the “Put Right”) set forth in Section 6(b) hereof. 
 6. Refusal to Transfer; Put Right. 
 (a) Refusal to Transfer.
Any attempt by any Seller to Transfer any Shares in violation of any provision of this Agreement will be void. The Company will not be required (i) to transfer on its books any Shares that have been sold, gifted or otherwise Transferred in
violation of this Agreement, or (ii) to treat as owner of such Shares, or to accord the right to vote or pay dividends to any purchaser, donee or other transferee to whom such Shares may have been so Transferred. 

(b) Put Right. If a Seller Transfers any Shares in contravention of the Co-Sale Eligible Investors’ Right of Co-Sale under
this Agreement (a “Prohibited Transfer”), or if the Proposed Transferee of Offered Shares desires to purchase a class, series or type of shares offered by the Seller but not held by a Co-Sale Eligible Investor or the Proposed
Transferee is unwilling to purchase any Shares from a Co-Sale Eligible Investor, such Co-Sale Eligible Investor may, by delivery of written notice to such Seller (a “Put Notice”) within ten (10) days after the later of
(i) the Closing as defined in Section 4(a) above, or (ii) the date on which such Co-Sale Eligible Investor becomes aware of the Prohibited Transfer or the terms thereof, require such Seller to purchase from such Co-Sale Eligible
Investor, for cash or such other consideration as the Seller received in the Prohibited Transfer or at the Closing, a number of Shares (of the same class or type as Transferred in the Prohibited Transfer or at the Closing if such Co-Sale Eligible
Investor then owns Shares of such class or type; otherwise Series A Shares, Series B-1 Shares or Ordinary Shares) having a purchase price (on an as-converted basis) equal to the aggregate purchase price that the Co-Sale Eligible Investor would have
received in the closing of such Prohibited Transfer if such Co-Sale Eligible Investor had elected to exercise its Right of Co-Sale with respect thereto or in the Closing if the Proposed Transferee had been willing to purchase the Shares of the
Co-Sale Eligible Investor (the “Put Shares”). The closing of such sale to the Seller will occur within ten (10) days after the date of such Co-Sale Eligible Investor’s Put Notice to such Seller. Upon the closing of the
transaction contemplated by the Put Notice, Seller shall also reimburse the Co-Sale Eligible Investor for any and all fees and expenses, including, but not limited to, legal fees and expenses, incurred pursuant to the exercise or attempted exercise
of such Co-Sale Eligible Investor’s Rights of Co-Sale pursuant to Section 4 or in the exercise of its rights under this Section 6 with respect to the Put Shares.

 7. Restrictive Legend and Stop-Transfer Orders. 

(a) Legend. The Key Shareholders understand and agree that the Company will cause the legend set forth below, or a legend
substantially equivalent thereto, to be placed upon any certificate(s) or other documents or instruments evidencing ownership of Shares by each Key Shareholder: 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AND MAY ONLY BE SOLD, DISPOSED OF OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH CERTAIN RIGHTS OF FIRST REFUSAL AND RIGHTS OF CO-SALE AS SET
FORTH IN A RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT ENTERED INTO BY THE HOLDER OF THESE SHARES, THE COMPANY AND CERTAIN MEMBERS OF THE COMPANY. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH RIGHTS OF FIRST
REFUSAL AND RIGHTS OF CO-SALE ARE BINDING ON TRANSFEREES OF THESE SHARES.” 
 (b) Stop Transfer Instructions. In
order to ensure compliance with the restrictions referred to herein, each Seller agrees that the Company may issue appropriate “stop transfer” certificates or instructions. 

(c) Transfers. No securities shall be Transferred unless (i) such Transfer is made in compliance with applicable federal and
state securities laws and (ii) prior to such Transfer, the transferee or transferees, who prior to such Transfer are not already parties to this Agreement, sign a counterpart to this Agreement pursuant to which it or they agree to be bound by
the terms of this Agreement. 
 8. Termination. This Agreement shall terminate and be of no further force or
effect upon the earlier to occur of: (a) the effectiveness of the registration statement for the Company’s first firm commitment underwritten public offering registered under the Securities Act, or pursuant to the securities laws
applicable to an offering of securities in another jurisdiction pursuant to which such securities will be listed on an internationally-recognized securities exchange; or (b) the effectiveness of a Deemed Liquidation Event.

through an internationally recognized express courier service, delivery fees pre-paid, and to have been effected three (3) business days following the day the same is sent as aforesaid.

to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. 

(c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree
to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded, and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 
 (d) Waivers and Amendment. Subject to Section 9(n), with the written consent of Investors holding at least a majority of the then outstanding Series A Shares and Series B-1 Shares (voting
together as a single class on an as-converted basis), the obligations of the Company, the Key Shareholders and the rights of the Eligible Investors under this Agreement may be waived (either generally or in a particular instance, either
retroactively or prospectively and either for a specified period of time or indefinitely), and with the same consent the Company, when authorized by resolution of its Board of Directors, may enter into a supplementary agreement for the purpose of
adding any provisions to or changing or waiving in any manner or eliminating any of the provisions of this Agreement, provided, however, that any amendment, waiver, discharge or termination that, by its terms, adversely affects the
rights of the Key Shareholders hereunder in a materially disproportionate manner shall not be effective unless approved by the Key Shareholders; provided, 

  
 -9-









 
further, that any amendment, waiver, discharge or termination that, by its terms, adversely affects the rights of the holders of Series B-1 Shares in a materially disproportionate manner
shall not be effective unless approved by the holders of a majority of the Series B-1 Shares; provided, further, that for the purposes of this Section 9(d), the amendment of Sections 1(b) or 1(k) to alter the respective
shareholding threshold numbers set forth therein or the amendment of Sections 1(f) or 1(g) in a manner adverse to the holders of Series B-1 Shares shall be deemed materially adverse to and require the approval of the holders of a majority of the
Series B-1 Shares. For avoidance of doubt, the Company and Investors holding at least a majority of the then outstanding Series A Shares and Series B-1 Shares (voting as a single class) may, without the consent of the Key Shareholders, amend this
Agreement to add new Key Shareholders or other Investors and to provide that securities held by such persons will be bound by the terms hereof. Upon the effectuation of each such waiver, consent, agreement, amendment or modification the Company
shall promptly give written notice thereof to the record holders of the Series A Shares and/or the Series B-1 Shares who have not previously consented thereto in writing. Neither this Agreement nor any provisions hereof may be changed, waived,
discharged or terminated orally, except by a signed statement in writing. 
 (e) Continuity of Other Restrictions. Any
Shares not purchased by the Company or any ROFR Eligible Investor under their Right of First Refusal hereunder will continue to be subject to all other restrictions imposed upon such Shares by law, including any restrictions imposed under the
Articles. 
 (f) Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the
internal laws of the State of California as such laws are applied to agreements between California residents entered into and to be performed within California. Each of the Parties irrevocably: (a) agrees that any dispute or controversy arising
out of, relating to, or concerning any interpretation, construction, performance or breach of this Agreement, shall be settled by arbitration to be held in the State of California, in accordance with the rules then in effect of the American
Arbitration Association; (b) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such arbitration; and (c) submits to the exclusive jurisdiction of the
State of California in any such arbitration. The Parties hereby acknowledge and agree that (a) any decision of the arbitrator shall be final, conclusive and binding on the parties to the arbitration; (b) judgment may be entered on the
arbitrator’s decision in any court having jurisdiction; and (c) the parties to the arbitration shall each pay an equal share of the costs and expenses of such arbitration, and each such party shall separately pay for its respective counsel
fees and expenses; provided, however, that the prevailing party in any such arbitration shall be entitled to recover from the non-prevailing party its reasonable costs and attorney fees. 

(g) Specific Enforcement. Except as otherwise provided herein, any and all remedies expressly conferred upon a party by this
Agreement will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties
hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be
entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any federal or state court in the State of California, this being in addition to any other remedy to
which they are entitled at law or in equity.

(i) Counterparts; Facsimiles. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. A facsimile, telecopy or other reproduction of this Agreement may be executed by one or more parties hereto and delivered by such party by facsimile or any similar

upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or
approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the
