Participation”). 

  
 4 

 3.2. Pro Rata Share. A Participation Rights Holder’s “Pro Rata
Share” for purposes of the Right of Participation is equal to the product obtained by multiplying (x) the aggregate number of the New Securities to be issued by the Company by (y) a fraction, the numerator of which is the number

Participation Rights Holders who have elected to exercise the Right of Participation (calculated on a fully-diluted and as-converted basis) immediately prior to the issuance of New Securities giving rise to
the Right of Participation. For the purpose of this Agreement, “fully-diluted” means, with respect to the capitalization of the Company, all warrants, options and convertible securities of the Company are taken into account and
assumed to be exercised. 
 3.3. New Securities. “New Securities” shall mean, collectively, equity securities of the
Company, whether or not currently authorized, as well as any Preferred Shares, Ordinary Shares or other voting shares of the Company and rights, options or warrants to purchase such Preferred Shares, Ordinary Shares and securities of any type
whatsoever that are, or may become, convertible or exchangeable into such Preferred Shares, Ordinary Shares or other voting shares, provided, however, that the term “New Securities” shall not include: 

(a) any Ordinary Shares (and/or options or warrants therefor) issued to employees, officers, directors, contractors, advisors or consultants

defined under the Series D Purchase Agreement), as such agreements may be amended from time to time, and any Ordinary Shares issued pursuant to the conversion of any Preferred Shares; 

(c) any securities issued in connection with any share split, share dividend or other similar event in which all Participation Rights Holders
are entitled to participate on a pro rata basis; 
 (d) any securities issued pursuant to the acquisition of another corporation or entity
by the Company by consolidation, merger, purchase of assets, or other reorganization duly approved in accordance with this Agreement and Restated Articles in which the Company acquires, in a single transaction or a series of related transactions,
all or substantially all assets of such other corporation or entity, or fifty percent (50%) or more of the equity ownership or voting power of such other corporation or entity, as duly approved by the Board (including the affirmative votes of
Majority Investor Directors); and, 
 (e) any securities issued pursuant to a Qualified IPO or for the adjustment pursuant to Article 39 (e)

 3.4. Procedures. 

(a) Participation Notice. In the event that the Company proposes to undertake an issuance of New Securities (in a single transaction or
a series of related transactions), it shall give to each Participation Rights Holder written notice of its intention to issue New Securities (the “Participation Notice”), describing the amount and type of New Securities, the price
and the general terms upon which the Company proposes to issue such New Securities. Each Participation Rights Holder shall have thirty (30) days from the date of receipt of any such Participation Notice (the “Participation
Period”) to agree in writing to purchase such Participation Rights Holder’s Pro Rata Share of such New Securities for the price and upon the terms and conditions specified in the Participation Notice by giving written notice to the
Company and stating therein the quantity of New Securities to be purchased (not to exceed such Participation Rights Holder’s Pro Rata Share) (the “Purchase Notice”). If any Participation Rights Holder fails to so agree in
writing within Participation Period to purchase such Participation Rights Holder’s full Pro Rata Share of an offering of New Securities, then such Participation Rights Holder shall forfeit the right hereunder to purchase that part of its Pro
Rata Share of such New Securities that it did not agree to purchase. 
 (b) Each Participating Rights Holder who exercised their Right of
Participation (the “Right Participant”) shall be obligated to buy such number of New Securities as determined by the Company pursuant to this Section 3.4 and the Company shall so notify the Right
Participants within five (5) days following the receipt of the Purchase Notice from the Participating Rights Holder. 
 3.5.
Oversubscription. If any Participating Rights Holder fails or declines to exercise fully its Rights of Participation in accordance with Section 3.4, the Company shall promptly give a written notice (the
“Second Participation Notice”) within five (5) days from the end of Participation Period to the Right Participants who agreed to exercise their Right of Participation in full in accordance with
Section 3.4 (the “Oversubscribing Right Participant”). Each Oversubscribing Right Participant shall have fifteen (15) days from the date of the Second Participation Notice (the “Second
Participation Period”) to notify the Company in written form of its desire to purchase the New Securities in excess of its Pro Rata Share, stating the number of the additional New Securities it proposes to purchase. If as a result thereof,
such oversubscription exceeds the total number of the remaining New Securities available for purchase, the Oversubscribing Right Participants will be cut back by the Company with respect to their oversubscriptions to that number of remaining New
Securities equal to the lesser of (a) the number of the additional Shares it proposes to purchase, or (b) the product obtained by multiplying (i) the number of the remaining New Securities available for subscription by (ii) a
fraction the numerator of which is the number of Ordinary Shares (calculated on a fully diluted and an as-converted basis) held by each Oversubscribing Right Participant and the denominator of which is the
total number of Ordinary Shares (calculated on a fully diluted and an as-converted basis) held by all the Oversubscribing Rights Participants. The Company shall so notify the Right Participants within five
(5) days from the end of the Second Participation Period. Notwithstanding anything to the contrary contained herein, the transaction in connection with the New Securities purchased by the Participation Rights Holder pursuant to this
Section 3 shall be consummated within sixty-five (65) days following the receipt of the Purchase Notice from the Right Participants in respect of the desire to purchase such New Securities. 

  
 6 

 3.6. Failure to Exercise. Upon the expiration of the Second Participation Period, or
in the event no Participating Rights Holder exercise the Right of Participation within Participation Period, the Company shall have one hundred and twenty (120) days thereafter to complete the sale of the New Securities described in the
Participation Notice (with respect to which the Right of Participation and oversubscription right hereunder were not exercised) at the same or higher price and upon non-price terms not materially more
favorable to the purchasers thereof than specified in the Participation Notice, provided that the prospective purchaser of such New Securities shall comply with this Agreement and Restated Articles, as maybe amended from time to time, to the fullest
extent or otherwise approved by the Participation Rights Holders. In the event that the Company has not issued and sold such New Securities within such one hundred and twenty (120) days period, then the Company shall not thereafter issue or
sell any New Securities without again first offering such New Securities to the Participation Rights Holders pursuant to this Section 3. 

4. TRANSFER RESTRICTIONS. 

4.1. Restriction on Transfers. Except for transfers by a holder of Ordinary Shares to its Permitted Transferees as provided in
Section 4.4, none of the holders of Ordinary Shares (excluding Tianjin Yuanjufu, Easy Benefit Investment Limited and their respectively permitted assignees to whom its rights have been duly assigned in accordance with this
Agreement) or their Permitted Transferees shall, without the written approval of the Board (including the affirmative votes of both Investor Directors), sell, assign, transfer, pledge, hypothecate, mortgage, encumber or otherwise dispose through one
or a series of transactions any Company securities held by it (“Restricted Shares”) to any person (the “Transfer”), on or prior to a Qualified IPO. Any attempt by a Party to transfer any Restricted Shares in
violation of this Section 4 shall be void and the Company hereby agrees it will not effect such a Transfer nor will it treat any alleged transferee as the holder of such Shares without the written approval of the Board
(including the affirmative votes of both Investor Directors). 
 4.2. Right of First Refusal to Transfer of Restricted Shares. Subject
to Section 4.4 of this Agreement, if any Ordinary Shareholder (excluding Tianjin Yuanjufu, Easy Benefit Investment Limited and their respectively permitted assignees to whom its rights have been duly assigned in accordance
with this Agreement) (the “Selling Shareholder”) proposes to Transfer any Restricted Shares held by it to any person (other than the Permitted Transferee as defined in Section 4.4), then such Selling
Shareholder shall promptly give written notice (the “Transfer Notice”) to each Preferred Shareholder (the “ROFR Holders”) and the Company prior to such sale or transfer. The Transfer Notice shall describe in
reasonable detail the proposed sale or transfer including, without limitation, the number of Restricted Shares to be sold or transferred (the “Offered Shares”), the nature of such sale or transfer, the consideration to be paid, and
the name and address of each prospective purchaser or transferee. The ROFR Holders shall have an option for a period of thirty (30) days from receipt of the Transfer Notice (the “ROFR Holder’s First Refusal
Period”) to elect to purchase the Offered Shares at the same price and subject to the same terms and conditions as described in the Transfer Notice. The ROFR Holders may exercise such purchase option and purchase all or any portion of the
Offered Shares by notifying the Selling Shareholder in writing before expiration of such thirty (30) days period as to the number of shares that it wishes to purchase. Each ROFR Holder will have the right, exercisable upon written notice (the
“ROFR Holder’s First Refusal Notice”) to the Selling Shareholder and the Company within the ROFR Holder’s First Refusal Period of its election to exercise its right of first refusal hereunder. The ROFR
Holder’s First Refusal Notice shall set forth the number of Offered Shares that such ROFR Holder wishes to purchase, which amount shall not exceed the First Refusal Allotment (as defined below) of such ROFR Holder. Such right of first refusal
shall be exercised as follows: 

  
 7 

 (a) First Refusal Allotment. Each ROFR Holder shall have the right to purchase up to
that number of the Offered Shares (the “First Refusal Allotment”) equivalent to the product obtained by multiplying the aggregate number of the Offered Shares by a fraction, the numerator of which is the number of Ordinary Shares
(on an as-converted basis) held by such ROFR Holder at the time of the transaction and the denominator of which is the total number of Ordinary Shares (on an
as-converted basis) owned by all ROFR Holders at the time of the transaction who have elected to participate in the right of first refusal purchase. A ROFR Holder shall not have a right to purchase any of the
Offered Shares unless it exercises its right of first refusal within the ROFR Holder’s First Refusal Period. To the extent that any ROFR Holder does not exercise its right of first refusal in connection with any or all of its First Refusal
Allotment, the Selling Shareholder and the exercising ROFR Holders that intend to purchase the Offered Shares in excess of its First Refusal Allotment (the “Over-subscription ROFR Holders”) shall, at the Over-subscription ROFR
Holders’ sole discretion, within five (5) days after the end of the ROFR Holder’s First Refusal Period, make such adjustment to the First Refusal Allotment of each Over-subscription ROFR Holder so that any remaining Offered Shares may
be allocated to the Over-subscription ROFR Holders on a pro rata basis. 
 (b) Purchase Price and Payment. The purchase price for the
Offered Shares to be purchased by the ROFR Holders exercising their right of first refusal will be the price set forth in the Transfer Notice. The transaction in connection with the Offered Shares purchased by the ROFR Holders shall be consummated
within fifteen (15) days following the date of the ROFR Holder’s First Refusal Notice by wire transfer or check as directed by the Selling Shareholder. 

(c) Expiration Notice. Within five (5) days after the expiration of the ROFR Holder’s First Refusal Period, the Company will
give written notice (the “First Refusal Expiration Notice”) to the Selling Shareholder and the ROFR Holders specifying either (i) that all of the Offered Shares were subscribed by the ROFR Holders exercising their rights of
first refusal, or (ii) that the ROFR Holders have not subscribed for all of the Offered Shares in which case the First Refusal Expiration Notice will specify the Co-Sale Pro Rata Portion (as defined
below) of the remaining Offered Shares for the purpose of the co-sale right of the holders of the Preferred Shares described in the Section 4.3 below provided that such Selling
Shareholder shall be any BVI Company or Founder. 
 (d) Rights of a Selling Shareholder. If any ROFR Holder exercises its right of
first refusal to purchase the Offered Shares, then, upon the date the notice of such exercise is given by the ROFR Holder, the Selling Shareholder will have no further rights as a holder of such Offered Shares except the right to receive payment for
such Offered Shares from such ROFR Holder in accordance with the terms of this Agreement, and the Selling Shareholder will forthwith cause all certificate(s) evidencing such Offered Shares to be surrendered to the Company for transfer to such ROFR
Holder. 
 4.3. Co-Sale Right. In the event that any BVI Company or Founder (the
“Co-Sale Selling Shareholder”) proposes to Transfer any Restricted Shares directly or indirectly held by it to any third party (other than the existing Shareholders of the Company) and the
ROFR Holders have not exercised their right of first refusal with respect to any of the Offered Shares (the “Co-Sale Holders”), then the remaining Offered Shares not subscribed for under the
right of first refusal pursuant to Section 4.2 above shall be subject to co-sale rights under this Section 4.3 and each
Co-Sale Holder shall have the right, exercisable upon written notice to the Co-Sale Selling Shareholder and the Company (the
“Co-Sale Notice”) within fifteen(15) days after receipt of First Refusal Expiration Notice (the “Co-Sale Right Period”), to participate
in such sale of the Offered Shares on the same terms and conditions as set forth in the Transfer Notice. The Co-Sale Notice shall set forth the number of Ordinary Shares (on both an absolute and as-converted to Ordinary Shares basis) that such Co-Sale Holder wishes to include in such sale or transfer, which amount shall not exceed the
Co-Sale Pro Rata Portion (as defined below) of such Co-Sale Holder. To the extent one or more of the Co-Sale Holders exercise
such right of participation in accordance with the terms and conditions set forth below, the number of Restricted Shares that such Co-Sale Selling Shareholder may sell in the transaction shall be
correspondingly reduced. The co-sale right of each Co-Sale Holder shall be subject to the following terms and conditions: 

  
 8 

 (a) Co-Sale Pro Rata Portion. Each Co-Sale Holder may sell all or any part of that number of Ordinary Shares (on an as-converted basis) held by it that is equal to the product obtained by multiplying
(x) the aggregate number of the Offered Shares subject to the co-sale right hereunder by (y) a fraction, the numerator of which is the number of Ordinary Shares (on an
as-converted basis) owned by such Co-Sale Holder at the time of the sale or transfer and the denominator of which is the combined number of Ordinary Shares (on an as-converted basis) at the time owned by all Co-Sale Holders who elect to exercise their co-sale rights (if any Co-Sale Holder does not elect to exercise the co-sale right to the full extent then its Ordinary Shares (on as-converted basis) for
calculation in the denominator shall be proportionately reduced) and the Co-Sale Selling Shareholder (“Co-Sale Pro Rata Portion”); provided that,
without prejudice to the provisions in Section 7.2, in the event that any Founder or any BVI Company proposes to sell or transfer any Restricted Shares directly or indirectly held by it to any third party (other than the existing shareholders
of the Company) and such sale or transfer will result in the change of the ultimate controller(s) and/or controlling shareholder(s) of the Company, the denominator of the fraction in the Co-Sale Pro Rata
Portion shall be the combined number of Ordinary Shares (on an as-converted basis) at the time owned by all Co-Sale Holders who elect to exercise their co-sale rights (if any Co-Sale Holder does not elect to exercise the co-sale right to the full extent then its Ordinary Shares (on as-converted basis) for calculation in the denominator shall be proportionately reduced); for the avoidance of doubt, it being understood that Preferred Shareholders shall be entitled to sell or transfer, with
priority to any other shareholders, all or any portion of its shares to any third party on the same terms and conditions under such circumstance. 

(b) Transferred Shares. Each Co-Sale Holder shall effect its participation in the sale by
promptly delivering to the Co-Sale Selling Shareholder for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent: 

(i) the number of Ordinary Shares which such Co-Sale Holder elects to sell; 

(ii) that number of Preferred Shares which is at such time convertible into the number of Ordinary Shares that such Co-Sale Holder elects to sell; provided in such case that, if the prospective purchaser objects to the delivery of Preferred Shares in lieu of Ordinary Shares, such
Co-Sale Holder shall convert such Preferred Shares into Ordinary Shares and deliver Ordinary Shares as provided in Subsection 4.3(b)(i) above. The Company agrees to make any such conversion concurrent
with the actual transfer of such shares to the purchaser; or 
 (iii) a combination of the above. 

  
 9 

 (c) Payment to Co-Sale Holder. The share
certificate or certificates that the Co-Sale Holder delivers to the Co-Sale Selling Shareholder pursuant to Section 4.3(b) shall be transferred
to the prospective purchaser in consummation of the sale of the Offered Shares pursuant to the terms and conditions specified in the Transfer Notice, and the Co-Sale Selling Shareholder shall concurrently
therewith remit to such Co-Sale Holder that portion of the sale proceeds to which such Co-Sale Holder is entitled by reason of its participation in such sale. To the
extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase any shares or other securities from a Co-Sale Holder exercising its
co-sale right hereunder, the Co-Sale Selling Shareholder shall not sell to such prospective purchaser or purchasers any Ordinary Shares unless and until, simultaneously
with such sale, the Co-Sale Selling Shareholder shall purchase such shares or other securities from such Co-Sale Holder. 

(d) Right to Transfer. To the extent the ROFR Holders do not elect to purchase, or the Co-Sale
Holders do not to participate in the sale of, any or all of the Offered Shares subject to the Transfer Notice, the Selling Shareholder may, not later than ninety (90) days following delivery to the Company and each of the Preferred Shareholder
of the Transfer Notice, conclude a Transfer of the Offered Shares covered by the Transfer Notice and not elected to be purchased by the ROFR Holders, which in each case shall be on substantially the same terms and conditions as those described in
the Transfer Notice. Any prospective purchaser of such shares shall comply with this Agreement and Restated Articles, as maybe amended from time to time, to the fullest extent. Any proposed transfer on terms and conditions which are materially
different from those described in the Transfer Notice, as well as any subsequent proposed transfer of any Restricted Shares by the Selling Shareholder, shall again be subject to the right of first refusal of the ROFR Holders and the co-sale right of the Co-Sale Holders (in the event that the proposed Transfer is made by any Co-Sale Selling Shareholder) and shall
require compliance by the Selling Shareholder with the procedures described in Sections 4.2 and 4.3 of this Agreement (in the event that the proposed Transfer is made by any Co-Sale Selling
Shareholder). 
 4.4. Permitted Transfers. Notwithstanding anything to the contrary contained herein, the right of first
refusal and co-sale rights as set forth in Section 4.2 and Section 4.3 above shall not apply to (a) any Transfer of Restricted Shares 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 under the ESOP or other similar plan or arrangement as approved according to
Section 11; (b) any Transfer of Restricted Shares to employees, officers or directors of the Company pursuant to the ESOP or other similar plan or arrangement of the Company as approved according to
Section 11 and (c) Transfer of any Restricted Shares held by the BVI Company, a Founder or another Ordinary Shareholders to the Founder’s or the Ordinary Shareholder’s individual beneficiary owner’s
parents, children or spouse, or to a trustee for the benefit of such persons for bona fide estate planning purposes provided that the voting right with respect such Restricted Shares are still vested in the transferring Ordinary Shareholder (each
transferee pursuant to the foregoing subsections (a), (b) and (c), a “Permitted Transferee”); provided further that adequate documentation therefor is provided to the Preferred Shareholders to their satisfaction and that any such
Permitted Transferee agrees in writing to be bound by this Agreement and the Restated Articles in place of the relevant transferor (including the provision of restriction on transfer); provided, further, that such transferor shall remain liable for
any breach by such Permitted Transferee of any provision hereunder. 

  
 10 

 4.5. The shareholders specifically agree that the restrictions with regard to the Transfer
of the Restricted Shares by the Ordinary Shareholders as described under this Section 4 shall apply equally to Transfer of the shares of each Ordinary Shareholders (as applicable) (excluding Tianjin Yuanjufu, Easy Benefit
Investment Limited and their respectively permitted assignees to whom its rights have been duly assigned in accordance with this Agreement, and each of such Ordinary Shareholders, a “Restricted Ordinary Shareholder”), as if each of
the provisions under this Section 4 has been repeated under this Section 4.5 with regard to Transfer of the shares of each Restricted Ordinary Shareholder except that the reference to the shares in
the Company has been revised to refer to the shares in each Restricted Ordinary Shareholder, as applicable, so that the result of such restrictions on the indirect Transfer of the shares in the Company by transferring the shares in each Restricted
Ordinary Shareholder is the same as if such Restricted Ordinary Shareholder directly transfers the relevant shares in the Company. 
 4.6.
Restriction on Indirect Transfers. Notwithstanding anything to the contrary contained herein, without the prior written approval of the Board (including the affirmative votes of both Investor Directors): 

(a) (i) the Founders and/or the BVI Company shall not, directly or indirectly, Transfer any equity interest held directly or indirectly, to
any person; and (ii) the Founders or BVI Company shall not, issue to any person any equity securities of the Founders or BVI Company or any options or warrants for, or any other securities exchangeable for or convertible into, such equity
securities of the Founders or BVI Company. 
 (b) the Founders and the BVI Company shall not, or shall not cause or permit any other person
to, directly or indirectly, Transfer any equity interest held or controlled by him or the BVI Company respectively in the Company to any person. Any Transfer in violation of this Section shall be void and the Company hereby agrees it will not effect
such a Transfer nor will it treat any alleged transferee as the holder of such equity interest. 
 (c) Except in compliance with this
Agreement, each Group Company shall not, and the Founders and/or the BVI Company shall not (i) Transfer any equity interest held, directly or indirectly, by it or him in the Group Companies to any person; and (ii) cause any Group Company
to, issue to any person any equity securities of such Group Company, or any options or warrants for, or any other securities exchangeable for or convertible into, such equity securities of such Group Company. 

4.7. Guarantees by the Founders. The Founders hereby guarantee and warrant the performance and obligations of the BVI Company under this
Agreement. 
 4.8. Legend. 

(a) Each certificate representing the Restricted Shares held by Ordinary Shareholders shall be endorsed with the following legend: 

“THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN RESTRICTIONS ON
TRANSFER SET FORTH IN A SHAREHOLDERS AGREEMENT, A COPY OF WHICH MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.” 

  
 11 

 (b) Each Party agrees that the Company may instruct its transfer agent to impose transfer
restrictions on the shares represented by certificates bearing the legend referred to in Section 4.8 (a) above to enforce the provisions of this Agreement and the Company agrees to promptly do so. The legend shall be
removed upon termination of the provisions of this Section 4. 
 4.9. Transfer by the
Investors. None of the Preferred Shareholders shall transfer any Shares directly or indirectly owned by it to any Competitors. Any Preferred Shareholder may transfer any Shares held by it (including any rights and obligations under
the Transaction Documents) to any of its Affiliates without being subject to consent from any other Parties and the restrictions of other preferred rights (including but not limited to the restrictions under this Section 4.9 and any other
applicable laws). If any Preferred Shareholder (the “Selling Preferred Shareholder”) proposes to sell or transfer any Shares held by it to any person other than one of its Affiliates (provided that such transferee is not a
Competitor of the Group Companies), then such Selling Preferred Shareholder shall promptly give written notice (the “Preferred Transfer Notice”) to other Shareholders (the “Preferred ROFR Holders”) prior to
such sale or transfer. The Preferred Transfer Notice shall describe in reasonable detail the proposed sale or transfer including, without limitation, the number of Shares to be sold or transferred (the “Offered Preferred Shares”),
the nature of such sale or transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee. Subject to Section 9 hereof, any attempt by an Investor to transfer any shares in
violation of this Section 4.9 shall be void and result in the termination of the Information and Inspection Rights, the right to appoint and remove the director or other priority right of such Investor, and the Company
hereby agrees it will not effect such a Transfer nor will it treat any alleged transferee as the holder of such Shares. 
 (a) The Preferred
ROFR Holders shall have an option for a period of fifteen (15) days from receipt of the Preferred Transfer Notice (the “Preferred Offering Period”) to elect to purchase its Pro Rata ROFR Share (as defined below) of the Offered
Preferred Shares at the same price and subject to the same terms and conditions as described in the Preferred Transfer Notice. The Preferred ROFR Holders may exercise such purchase option and purchase its respective Pro Rata ROFR Share of the
Offered Preferred Shares by notifying the Selling Preferred Shareholder in writing (the “Acceptance Notice”) before expiration of the Preferred Offering Period; such notice shall indicate that the Preferred ROFR Holder accepts the
price, terms and conditions set forth in the Preferred Transfer Notice and such Acceptance Notice shall be binding on the Preferred ROFR Holder. 

(b) Each Preferred ROFR Holder’s “Pro Rata ROFR Share” is equal to the product obtained by multiplying the aggregate
number of the Offered Preferred Shares by a fraction, the numerator of which is the number of Ordinary Shares (on an as-converted basis) held by such Preferred ROFR Holder on the date of the Preferred Transfer
Notice and the denominator of which is the total number of Ordinary Shares (on an as-converted basis) owned by all Preferred ROFR Holders at such time. A Preferred ROFR Holder shall not have a right to
purchase any of the Offered Preferred Shares unless it exercises its right of first refusal within the Preferred Offering Period. 
 (c)
Purchase Price and Payment. The purchase price for the Offered Preferred Shares to be purchased by the Preferred ROFR Holders exercising their right of first refusal will be the price set forth in the Preferred Transfer Notice. The
transaction in connection with the Offered Preferred Shares purchased by the Preferred ROFR Holders shall be consummated within thirty (30) days following the date of the Preferred ROFR Holder’s Acceptance Notice by wire transfer or check
as directed by the Selling Preferred Shareholder. 

  
 12 

 (d) Regardless of any other provision of this Agreement, if the Preferred ROFR Holders
decline in writing, or fail to deliver to the Selling Preferred Shareholder the Acceptance Notice in accordance with Section 4.9 (a) with respect to all (and not less than all) Offered Preferred Shares, or fails to close
the deal in accordance with the Preferred Transfer Notice and the Acceptance Notice, the Offered Preferred Shares shall be released in its entirety from this right of first refusal to Preferred Shares which shall be deemed as forfeited by the
Preferred ROFR Holders, and the Selling Preferred Shareholder shall be free to sell such Offered Preferred Shares within ninety (90) days from the expiration of Preferred Offering Period or the proposed closing date set forth in the Preferred
Transfer Notice (whichever is later), as the case may be, to the third-party transferee identified in the Preferred Transfer Notice upon terms and conditions (including the purchase price) no more favorable to the purchaser than those specified in
the Preferred Transfer Notice. 
 (e) For the avoidance of doubt, this Section 4.9 shall apply mutatis
mutandis to any proposed Transfer of Ordinary Shares held by Tianjin Yuanjufu and Easy Benefit Investment Limited. Unless otherwise provided under Section 4.9, Tianjin Yuanjufu, Easy Benefit Investment and the Preferred Shareholders (and
their respectively permitted assignees to whom its rights have been duly assigned in accordance with this Agreement) shall have right to transfer the Preferred Shares or Ordinary Shares issued or issuable upon conversion of Preferred Shares freely
and without any restrictions, without prejudice to the rights of the Preferred Shareholder to purchase any Offered Shares to be transferred by any other shareholders pursuant to Section 4.2 and
Section 4.3. 
 5. Drag-Along Right 

5.1. Drag-Along Sale. Without prejudice to the provisions in Section 6 and
Section 7.2, in the event that (i) the Company has not consummated an IPO or Acquisition before August 31, 2023, (ii) the Majority Series C Group Preferred Shareholders, voting as a separate class (the
“Drag Holders A”), or the Majority Series D Preferred Shareholders, voting as a separate class (the “Drag Holders B”, collectively with Drag Holders A, the “Drag
Holders”) approve a proposed Acquisition, and (iii) the implied valuation of the Company in such proposed Acquisition is no less than US$ three (3) hundred million (the “Drag-Along Sale”), the
Drag Holders shall have the rights to, by delivery of written notice (the “Drag-Along Notice”), require each of the other Shareholders of the Company(the “Dragged Holders”), to act as
follows, unless the Founders or Dragged Holders have proposed a bona fide alternative Acquisition within ten (10) days from the date of receipt of the Drag-Along Notice(a “Qualified Alternative Sale”), in which
(x) the implied valuation of the Company shall be higher than that proposed in the Drag-Along Sale; and (y) the terms and conditions shall be generally not less favorable than those proposed in Drag-Along Sale: 

(a) sell, at the same time as the Drag Holders sell to the relevant third party in the Drag-Along Sale, all of its Shares of the Company or
the same percentage of its Shares of the Company as the Drag Holders sell, for the same per-share consideration (on an as converted basis) and upon the same terms and conditions as were agreed to by the Drag
Holders; 
 (b) vote all of its Shares of the Company (i) in favor of such Drag-Along Sale (together with any related amendment or
restatement to the Articles required to implement such Drag-Along Sale of the Company), (ii) against any other proposal of Acquisition (other than a Qualified Alternative Sale); 

  
 13 

 (c) not exercise any dissenters’ or appraisal rights under applicable law with respect
to such Drag-Along Sale; and 
 (d) take all actions reasonably necessary to consummate the Drag- Along Sale, including but not limited to
execute any share transfer or associated agreements reasonably necessary for consummation of such Drag-Along Sale, and the delivery, at the closing of such Drag-Along Sale by way of a sale of shares, of all certificates representing the shares being
sold, accompanied by share transfer forms, or affidavits with respect to lost certificates required under the applicable law. 
 5.2.
Notwithstanding the foregoing, the Drag Holders shall promptly inform other Shareholders and the Company of their intention to propose a Drag-Along Sale in writing at least ten (10) days prior to the delivery of the Drag-Along Notice. 

5.3. In the event that any Dragged Holder fails for any reason to take any of the foregoing actions under Section 5.1
or purchase the securities in the Group Companies held by the Drag Holders as set forth below, after thirty (30) days upon the receipt of the Drag-Along Notice, such Dragged Holder hereby grants an irrevocable power of attorney and proxy to any
director approving the Drag-Along Sale to take all necessary actions and execute and deliver all documents deemed by such director to be reasonably necessary to effectuate the terms hereof. Notwithstanding any provision to the contrary in this
Section 5, the Dragged Holders may elect not to vote or give their consent with respect to, all the securities in Group Companies directly or indirectly held by them in favor of such proposed Drag-Along Sale, but in any
such event, the Dragged Holders shall be obliged to purchase all the securities in Group Companies held by the Drag Holders, under the same terms and conditions as offered in the proposed Drag-Along Sale. 

5.4. All the proceeds generated from the Drag-Along Sale shall be distributed as follows: 

(a) before any distribution or payment shall be made to the holders of any Ordinary Shares, each holder of Series D Preferred Shares, Series C
Group Preferred Shares, Series B Preferred Shares and Series A Preferred Shares shall be entitled to receive, on parity with each other, an amount equal to one hundred percent (100%) of the applicable Deemed Issue Price (as adjusted for any share
splits, share dividends, combinations, recapitalizations and similar transactions) for each Preferred Share it holds, plus all accrued or declared but unpaid dividends thereon (collectively “Drag-Along Preference”); 

(b) after full payment of the Drag-Along Preference to all the holders of the Preferred Shares pursuant to
Section 5.4(a) above, any remaining proceeds generated from the Drag-Along Sale shall be distributed on a pro rata, pari passu basis among the holders of the Preferred Shares (on an
as-converted basis), together with the holders of the Ordinary Shares. 
 5.5. Notwithstanding
anything to the contrary set forth herein, the Dragged Holders will not be required to comply with the foregoing Subsection 5.1 in connection with any proposed Drag-Along Sale of the Company (the “Proposed Sale”), unless:

  
 14 

 (a) any representations and warranties to be made by such Dragged Holder (excluding the
Founders, any person or entity controlled or beneficially owned by or affiliated with any Founder, or any Dragged Holder who is an employee or officer or controlling shareholder of any Group Company) in connection with the Proposed Sale are limited
to representations and warranties related to authority, ownership and the ability to convey title to such Shares, including, but not limited to, representations and warranties that (i) the Dragged Holder holds all right, title and interest in
and to the Shares such Dragged Holder purports to hold, free and clear of all liens and encumbrances, (ii) the obligations of the Dragged Holder in connection with the transaction have been duly authorized, if applicable, (iii) the
documents to be entered into by the Dragged Holder have been duly executed by the Dragged Holder and delivered to the acquirer and are enforceable (subject to customary limitations) against the Dragged Holder in accordance with their respective
terms; and (iv) neither the execution and delivery of documents to be entered into by the Dragged Holder in connection with the transaction, nor the performance of the Dragged Holder’s obligations thereunder, will cause a breach or
violation of the terms of any agreement to which the Dragged Holder is a party, or any law or judgment, order or decree of any court or governmental agency that applies to the Dragged Holder; 

(b) such Dragged Holder is not required to agree (unless such Dragged Holder is any Key Employee, any person or entity controlled or
beneficially owned by or affiliated with a Key Employee) to any restrictive covenant in connection with the Proposed Sale (including any covenant not to compete or covenant not to solicit customers, employees or suppliers of any party to the
Proposed Sale); 
 (c) the Dragged Holder is not liable for the breach of any representation, warranty or covenant made by any other Person
in connection with the Proposed Sale, other than the Company (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any shareholder
of any of identical representations, warranties and covenants provided by all shareholders); 
 (d) equal terms of liabilities in connection
with the Proposed Sale will apply to each Dragged Holder and Drag Holder who is a Preferred Shareholder; 
 (e) upon the consummation of the
Proposed Sale, each holder of each class or series of the shares of the Company will receive the same form and same amount of consideration per share for their shares of such class or series as is received by other holders in respect of their shares
of such same class or series of shares, and if any holders of any shares of the Company are given a choice as to the form of consideration to be received as a result of the Proposed Sale, all holders of such shares will be given the same option;
provided however, that nothing in this Subsection 5.4(e) shall entitle any holder to receive any form of consideration that such holder would be ineligible to receive as a result of such holder’s failure to satisfy any condition, requirement or
limitation that is generally applicable to the Company’s shareholders. 
 6. REDEMPTION 

6.1. Redemption by the Company and Founders. Notwithstanding anything to the contrary herein, upon the occurrence of any of the
following events (collectively the “Redemption Triggering Events”, and each a “Redemption Triggering Event”), subject to the applicable laws of the Cayman Islands and, if so requested by the relevant holder of the
Preferred Shares (each a “Redeeming Shareholder”), the Company and/or any Founder shall redeem or repurchase all or part of the outstanding Preferred Shares in cash out of funds legally available therefor (the
“Redemption”): 

  
 15 

 (a) for each holder of the Preferred Shares, (i) the Company has not consummated a
Qualified IPO before March 31, 2021; (ii) Yan Hai (阎海) and/or Wang Sizhen (王思振) directly or indirectly participates in or owns any interest in business of molecular diagnosis outside the Group Companies which
is substantially competitive with the Group Company (other than as a holder of less than five percent (5%) of the outstanding shares of a company without decision rights) and has not stopped it within sixty (60) days after the written notice
issued by any holder of Series C Group Preferred Shares and/or Series D Preferred Shares; (iii) any material violation of law or act of dishonesty committed by any Group Companies or any Founders; (iv) Yan Hai (阎海) and/or
Wang Sizhen (王思振) resigns from the Group Companies or no longer holds any Shares of the Company directly or indirectly; (v) any change in the laws and regulations or the reinterpretation or enforcement of such laws and
regulations, that causes the Control Documents invalid, illegal or unenforceable where (a) the Shareholders of the Company fail to revert to be the shareholders of the PRC Affiliate or reach an agreement with respect to any feasible alternative
arrangements satisfactory to the then Shareholders of the Company, and (b) there is Material Adverse Effect on the PRC Affiliate, within six (6) months after such change, reinterpretation or abolition of any law or regulation; or
(vi) the Company, the Founders or any other party terminate any Control Document or cause any Control Document to be terminated, unless otherwise approved by the Board (including the affirmative vote of the Majority Investor Directors); 

(b) for VIVO and/or each holder of the Series D Preferred Shares (in addition to its rights under Subsection 6.1 (a)), the VIE
structure or the Control Documents are rendered invalid, illegal or unenforceable by any change in the laws and regulations or the reinterpretation or enforcement of such laws and regulations, and/or the Company, with the approval of the Board
(including the affirmative votes of Majority Investor Directors), decides to unwind the VIE structure and cause the Shareholders of the Company to revert to be the shareholders of the PRC Affiliate or such other Subsidiary or Affiliate of the
Company in the PRC. 
 The price at which each Preferred Share shall be redeemed or repurchased (the “Redemption Price”) shall be calculated
by applying the following formula: 
 IP × (1+N×A) + D, and 

IP = the Deemed Issue Price; 
 N =
a fraction the numerator of which is the number of calendar days between the Original Issue Date and the relevant Redemption Date (as defined below) on which such Preferred Share is redeemed and the denominator of which is 365; 

A = 8% in the case of Series C-2 Preferred Shares, or 10% in the case of other Preferred Shares; 

D = all declared but unpaid dividends on each Preferred Share up to the Redemption Date, proportionally adjusted for share subdivisions, share
dividends, reorganizations, reclassifications, consolidations or mergers. 

  
 16 

 6.2. Notice. A notice of redemption (a “Redemption Notice”) by any
Redeeming Shareholder shall be given by hand or by mail to the Company at any time on or after the occurrence of Redemption Triggering Event stating the date on which the Preferred Shares shall be redeemed (the “Redemption Date”),
which shall be no more than sixty (60) days from the date of the Redemption Notice, and which shall be no earlier than the occurrence of the Redemption Triggering Event or the expiry of a thirty-days period from the date of the
Redemption Notice, whichever is later. Upon receipt of any Redemption Notice, the Company shall promptly give written notice of the redemption request to each non-requesting holder of record of the Preferred
Shares who has the right to redeem its Preferred Shares pursuant to Section 6.1 above, stating the existence of such request, the Redemption Price, the Redemption Date and the mechanics of redemption. For the avoidance of
doubt, the closing of the Redemption (the “Redemption Closing”) of any series of the Preferred Shares pursuant to this Section 6 will take place within ninety (90) days following the date of the
relevant Redemption Notice (the “Redemption Period”) at the offices of the Company. Notwithstanding anything to the contrary contained herein, no other Shares of the Company shall be redeemed unless and until the Company shall have
redeemed all of the Preferred Shares requested to be redeemed pursuant to this Section 6 and shall have paid all the Redemption Price for such Preferred Shares requested to be redeemed payable pursuant to this
Section 6. 
 6.3. Insufficient Funds. If the Company and/or the Founders fail (for whatever reason) to
redeem any Preferred Shares within six (6) months after the expiration of the Redemption Period, without prejudice to any other rights and remedies that the Redeeming Shareholder(s) may have and without relieving the Company or the Founder of
any of its obligations to redeem the Preferred Shares, the Redeeming Shareholder(s) who holds Series D Preferred Shares and whose Preferred Shares remain not redeemed shall be entitled to require the Company, the BVI Company and the Founders to
effect, and the Company, the BVI Company and the Founders shall be obligated to effect the liquidation of the Company. All proceeds generated therefrom shall be distributed in accordance with Section 7.1 below and
Section 129 of the Restated Articles. If the Company and/or any Founder does not have sufficient cash or funds legally available to redeem all of the Preferred Shares required to be redeemed at any Redemption Closing, those assets or funds
which are legally available shall be applied to redeem the maximum number of Preferred Shares which can be legally redeemed on a pro rata basis among the applicable Redeeming Shareholders thereof and payment of the relevant Redemption Price payable
in respect thereof. With respect to the remaining Preferred Shares not redeemed due to insufficient legal funds, such Preferred Shares shall remain outstanding, and the Redeeming Shareholders holding such redeeming Preferred Shares shall remain
entitled to all the rights, preferences and privileges provided in this Agreement, until such time as the Company or the Founder has sufficient legal funds to redeem such Preferred Shares. 

  
 17 

 6.4. Surrender of Certificates. Before any Redeeming Shareholder shall be entitled
for redemption under the provisions of this Section 6, such Redeeming Shareholder shall surrender his or her certificate or certificates representing such Preferred Shares to be redeemed (or in the case of a repurchase by
the Founder, also deliver an instrument of transfer executed by the Redeeming Shareholder) to the Company in the manner and at the place designated by the Company for that purpose, and the Redemption Price shall be payable on the Redemption Date to
the order of the person whose name appears on such certificate or certificates as the owner of such shares and each such certificate shall be cancelled on the Redemption Date. In the event less than all the shares represented by any such certificate
are redeemed, a new certificate shall be promptly issued representing the unredeemed shares. Unless there has been a default in payment of the applicable Redemption Price, upon cancellation of the certificate representing such Preferred Shares to be
redeemed, all dividends on such Preferred Shares designated for redemption on the relevant Redemption Date shall cease to accrue and all rights of the holders thereof, except the right to receive the Redemption Price thereof (including all accrued
and unpaid dividend up to the relevant redemption date), without interest, shall cease and terminate and such Preferred Shares shall cease to be issued shares of the Company. If the Company fails to redeem any Preferred Shares for which Redemption
is requested, then during the period from the Redemption Date through the date on which such Preferred Shares are actually redeemed and the Redemption Price is actually made, in full, such Preferred Shares shall continue to be outstanding and be
entitled to all rights and preferences of Preferred Shares. After payment in full of the aggregate Redemption Price for all issued and outstanding Preferred Shares, all rights of the holders thereof as Shareholders of the Company shall cease and
terminate and such Preferred Shares shall be cancelled. 
 6.5. Restriction on Distribution. If the Company and/or the Founders fail
(for whatever reason) to redeem any Preferred Shares on its due date for Redemption then, as from such date until the date on which the same are redeemed, the Company shall not declare or pay any dividend nor otherwise make any distribution of or
otherwise decrease its profits available for distribution. 
 6.6. To the extent permitted by law, the Company shall procure that the profits
of each Subsidiary and Affiliate of the Company for the time being legally available for distribution shall be paid to it by way of dividend or otherwise if and to the extent that, but for such payment, the Company would not itself otherwise have
sufficient profits available for distribution to make any redemption of Preferred Shares required to be made pursuant to this Section 6. 

6.7. Notwithstanding any other provisions of this Section 6, (i) the maximum liability of any Founder under this
Section 6 shall be limited to the amount equivalent to the fair market value of the Shares of the Company held by such Founder; and (ii) the Redeeming Shareholders shall first seek for redemption under the provisions
of this Section 6 from the Company and only in the event that the Company does not have sufficient cash or funds legally available to redeem all of the Preferred Shares required to be redeemed, the Redeeming Shareholders
may seek for redemption under the provisions of this Section 6 with respect to the remaining from the Founders other than the Company. 

7. LIQUIDATION. 
 7.1.
Liquidation Preference. In the event of any liquidation, dissolution or winding up of the Company (each a “Liquidation Event”), either voluntary or involuntary, distributions to the Shareholders of the Company shall be made
in the following manner: 
 (a) before any distribution or payment shall be made to the holders of any Series
C-2 Preferred Shares, Series C Preferred Shares, Series B Preferred Shares, Series A Preferred Shares and Ordinary Shares, each holder of Series D Preferred Shares shall be entitled to receive, on parity with
each other, an amount equal to one hundred percent (100%) of the Series D Issue Price, plus all dividends declared and unpaid with respect thereto (as adjusted for any share splits, share dividends, combinations, recapitalizations and similar
transactions) per Series D Preferred Share, then held by such holder (the “Series D Preference Amount”). If, upon the occurrence of any Liquidation Event, the assets of the Company shall be insufficient to make payment of the
foregoing amounts in full on all Series D Preferred Shares, then such assets shall be distributed among the holders of Series D Preferred Shares ratably in proportion to the full amounts to which they would otherwise be respectively entitled
thereon; 

  
 18 

 (b) after distribution or payment in full of the Series D Preference Amount pursuant to
Section 7.1(a), before any distribution or payment shall be made to the holders of any Ordinary Shares, each holder of Series C-2 Preferred Shares, Series C Preferred Shares, Series B
Preferred Shares and Series A Preferred Shares shall be entitled to receive, on parity with each other, an amount per Preferred Share equal to one hundred percent (100%) of the applicable Deemed Issue Price, plus all accrued or declared but unpaid
dividends thereon (Junior Shares Preference Amount”, collectively with the Series D Preference Amount, the “Preference Amount”). If, upon any Liquidation Events, the assets of the Company shall be insufficient to make
payment of the foregoing amounts in full on all Series C-2 Preferred Shares, Series C Preferred Shares, Series B Preferred Shares and Series A Preferred Shares, then such assets shall be distributed among the
holders of Series C-2 Preferred Shares, Series C Preferred Shares, Series B Preferred Shares and Series A Preferred Shares ratably in proportion to the full amounts to which they would otherwise be
respectively entitled thereon; 
 (c) after the full Preference Amount on all outstanding Preferred Shares has been paid pursuant to
Section 7.1(a) and (b) above, any remaining funds or assets of the Company legally available for distribution (together with the Preference Amount, the “Distribution Proceeds”) to Shareholders
shall be distributed on a pro rata, pari passu basis among the holders of the Preferred Shares (including the holders of Series D Preferred Shares) (on an as-converted basis), together with the holders of the
Ordinary Shares. 
 7.2. Liquidation on Acquisition. Unless otherwise waived in writing by all Preferred Shareholders or provided
under Section 5.4, each of an Acquisition (excluding the Drag-Along Sale) shall constitute and be treated as a Liquidation Event under this Section 7, and any proceeds, whether in cash or
properties, resulting from any such event shall be distributed in accordance with the terms of Section 7.1. 
 7.3.
Valuation of Properties. In the event the Company proposes to distribute assets other than cash pursuant to any Liquidation Event, the value of the assets to be distributed to the Shareholders shall be determined in good faith by the Board;
provided that any Shares not subject to investment letter or similar restrictions on free marketability shall be valued as follows: 
 (a)
If traded on a securities exchange, the value shall be determined based on the average of the security’s closing prices on such exchange over the thirty (30) day period ending one (1) day prior to the distribution; 

(b) If traded over-the-counter, the value shall be determined
based on the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the distribution; and 

(c) If there is no active public market, the value shall be the fair market value thereof as determined in good faith by the Board. 

Provided further that the method of valuation of securities subject to investment letter or other restrictions on free marketability shall be adjusted to make
an appropriate discount from the market value determined as above in clauses (a), (b) or (c) to reflect the fair market value thereof as determined in good faith by the Board. Subject to Section 5, the holders of at
least a majority of the outstanding Preferred Shares shall have the right to challenge any determination by the Board of fair market value pursuant to this Section 7.3, in which case the determination of fair market value
shall be made by an independent appraiser selected jointly by the Board and the challenging parties, the cost of such appraisal to be borne by the Company. 

  
 19 

 7.4. Notices. In the event that the Company shall propose at any time to consummate a
Liquidation Event, then, in connection with each such event, subject to any necessary approval required in this Agreement and Restated Articles, the Company shall send to the Preferred Shareholders at least thirty (30) days prior written notice
of the date when the same shall take place; provided, however, that the foregoing notice periods may be shortened or waived with the vote or written consent of the Preferred Shareholders. 

7.5. Notwithstanding any other provision of this Section 7, the Company may at any time, out of funds legally
available therefor and subject to compliance with the provisions of the applicable laws of the Cayman Islands, repurchase Ordinary Shares of the Company issued to or held by employees, officers or consultants of the Company (other than any of the
Founders) or its Subsidiaries upon termination of their employment or services, pursuant to any bona fide agreement providing for such right of repurchase, whether or not dividends on the Preferred Shares shall have been declared. 

7.6. Waiver of Liquidation Rights. Notwithstanding the foregoing, in the event that the Distribution Proceeds received or to be
received from an Acquisition (excluding the Drag-Along Sale) is in excess of US$ 1,250,000,000, all holders of Preferred Shares shall waive the liquidation preference rights provided in Section 7.1 on such Preferred Shares,
in which case, then subject to any then outstanding liquidation preference rights provided herein, all Distribution Proceeds of the Company shall be distributed ratably among the holders of Ordinary Shares and such holders of Preferred Shares on an as-converted basis. 
 8. REGISTRATION RIGHTS. 

The holders of the Registrable Securities shall be entitled to the rights as set forth in the Exhibit C with respect to any potential public offering of
Ordinary Shares of the Company (or securities representing such Ordinary Shares) in the United States, and to any analogous or equivalent rights with respect to any other offering of shares in any other jurisdiction pursuant to which the Company
undertakes to publicly offer or list such securities for trading on a recognized securities exchange. 
 9. ASSIGNMENT AND AMENDMENT. 

9.1. Assignment and Amendment. Notwithstanding anything herein to the contrary, this Agreement and the rights and obligations of
the Parties hereunder shall inure to the benefit of, and be binding upon, their respective successors, assigns and legal representatives, but shall not otherwise be for the benefit of any third party. Any rights of any Investors hereunder

transfer, provided that, unless waived by the Board, such Investor has provided a prior written notice to the Company of its intention to make such transfer and the name and address of the assignee; and provided further, that any such
assignee shall receive such assigned rights subject to all the terms and conditions of this Agreement. Notwithstanding the foregoing, each of the Investors may assign the rights and obligations under this Agreement to its Affiliates without any form
of consent of the other Parties, and the Company and other Parties hereto shall facilitate to effectuate such assignment upon such Investor’s request, provided that (i) such transfer is made in accordance with this Agreement, and
(ii) such successor shall not be the Competitor of the Group Companies and shall have obtained all necessary approval, authorization or consent with any Governmental Authority which are required to be obtained or made in connection with its
shareholding in the Company. This Agreement and the rights and obligations of each other Party hereunder shall not otherwise be assigned without the mutual written consent of the other Parties except as expressly provided herein. 

  
 20 

 9.2. Amendment of Rights. Any provision in this Agreement may be amended and the
observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only by the written consent of (i) as to the Company, only by the Company; (ii) as to the holders of Preferred
Shares, by the prior written approval of the holders of more than fifty percent (50%) of the then outstanding Preferred Shares (including the Majority Series D Preferred Shareholders) and their permitted assigns; provided, however, that the

 Exhibit B 

 EXHIBIT C 

Registration Rights 
 1.
Definitions. For purposes of this Exhibit C: 
 (a) Registration. The terms “register,” “registered,” and
“registration” refer to a registration effected by preparing and filing a registration statement under the Securities Act, and the declaration of effectiveness of such registration statement. 

(b) Registrable Securities. The term “Registrable Securities” means: (1) Ordinary Shares of the Company issued or
to be issued upon conversion of the Preferred Shares issued (A) under the Purchase Agreements and other share purchase agreements with respect to the Series A-1 Preferred Shares, Series A-2 Preferred Shares, Series B Preferred Shares, Series C Preferred Shares and Series C-2 Preferred Shares; and (B) pursuant to the issuance of New Securities by the
Company to the Investors pursuant to Section 3 hereof; (2) Ordinary Shares of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a dividend or
other distribution with respect to, or in exchange for or in replacement of, any of the foregoing; (3) any other Ordinary Share owned or hereafter acquired by the Investors, including Ordinary Shares issued in respect of the Ordinary Shares
described in (1)-(2) above upon any share split, share dividend, recapitalization or a similar event; and (4) any depositary receipts issued by an institutional depositary upon deposit of any of the foregoing. Notwithstanding the foregoing,
“Registrable Securities” shall not include any Registrable Securities sold by a Person in a transaction in which rights under this Exhibit C are not assigned in accordance with this Agreement or any Registrable Securities sold in a
public offering, whether sold pursuant to Rule 144 promulgated under the Securities Act, or in a registered offering, or otherwise. 
 (c)
Registrable Securities Then Outstanding. The number of shares of “Registrable Securities then outstanding” shall mean the number of Ordinary Shares of the Company that are Registrable Securities and are then issued and
outstanding or would be outstanding assuming full conversion of all Registrable Securities which are convertible into Ordinary Shares. 
 (d)
Holder. For purposes of this Exhibit C, the term “Holder” means any Person who holds Registrable Securities of record, whether such Registrable Securities were acquired directly from the Company or from another Holder in a
permitted transfer, to whom the rights under this Exhibit C have been duly assigned in accordance with this Agreement; provided, however, that for purposes of this Agreement, a record holder of the Preferred Shares convertible into
such Registrable Securities shall be deemed to be the Holder of such Registrable Securities; and provided, further, that (i) the Company shall in no event be obligated to register the Preferred Shares and that (ii) Holders of
Registrable Securities will not be required to convert their Preferred Shares into Ordinary Share in order to exercise the registration rights granted hereunder, until immediately prior to the declaration of effectiveness of the registration
statement for the offering to which the registration relates. 
 (e) Form S-3 and Form F-3. The terms “Form S-3” and “Form F-3” means such respective form under the Securities Act as
is in effect on the date hereof or any successor or comparable registration form under the Securities Act subsequently adopted by the SEC, which permits inclusion or incorporation of substantial information by reference to other documents filed by
the Company with the SEC. 

  
 Exhibit C 

 2. Demand Registration. 

(a) Request by Holders. If the Company shall receive, at any time after the earlier of (i) March 31, 2021, or (ii) one
hundred eighty (180) days after an IPO, a written request from the Holders of at least ten percent (10%) of the Registrable Securities, then outstanding that the Company files a registration statement under the Securities Act (other than Form F-3 or Form S-3) covering the registration of Registrable Securities pursuant to this Section 2 of Exhibit C, then the Company shall, within ten (10) Business Days
after the receipt of such written request, give a written notice of such request (the “Request Notice”) to all Holders. The Holders shall send a written notice stating the number of Registrable Securities requested to be registered
and included in such registration (the “Request Securities”) to the Company within ten (10) Business Days after receipt of the Request Notice. The Company shall thereafter use its best efforts to effect, as soon as practicable,
the registration of the Request Securities, subject only to the limitations of this Section 2 of Exhibit C. 
 (b) Underwriting.
If the Holders initiating the registration request under this Section 2 of Exhibit C (the “Initiating Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they
shall so advise the Company as a part of their request made pursuant to this Section 2 of Exhibit C and the Company shall include such information in the Request Notice referred to in Section 2(a) of Exhibit C. In the event of an
underwritten offering, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities
in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into
an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Holders of a majority of the Registrable Securities being registered and reasonably acceptable to the Company.
Notwithstanding any other provision of this Section 2 of Exhibit C, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so
advise all Holders of Registrable Securities which would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s)
and allocated among the Holders of Registrable Securities on a pro-rata basis according to the number of Registrable Securities then outstanding held by each Holder requesting registration (including the
Initiating Holders); provided, however, that the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced (x) by more than twenty percent (20%) and (y) unless all
other securities are first entirely excluded from the underwriting and registration including all shares that are not Registrable Securities and are held by any other Person, including any Person who is an employee, officer or director of the
Company or any Subsidiary of the Company. Further, if, as a result of such underwriter cutback, the Holders cannot include in the IPO at least eighty percent (80%) of the Registrable Securities that they have requested to be included therein, then
such Registration shall not be deemed to constitute one of the three (3) demand Registrations to which the Holders are entitled pursuant to this Exhibit C. If any Holder disapproves of the terms of any such underwriting, such Holder may elect
to withdraw therefrom by delivering a written notice to the Company and the underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn
from such underwriting shall be excluded and withdrawn from the registration. For any Holder that is a partnership, the Holder and the partners and retired partners of such Holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing Persons, and for any Holder that is a corporation, the Holder and all corporations that are affiliates of such Holder, shall be deemed to be a single “Holder,” and any pro-rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,”
as defined herein. 

  
 Exhibit C 

 (c) Maximum Number of Demand Registrations. The Company shall have no obligation to
effect more than three (3) registrations pursuant to this Section 2 of Exhibit C. 
 (d) Deferral. Notwithstanding the
foregoing, if the Company shall furnish to the Holders requesting the filing of a registration statement pursuant to this Section 2 of Exhibit C, a certificate signed by the president or chief executive officer of the Company stating that in
the good faith judgment of the Board, it would be materially detrimental to the Company and its shareholders for such registration statement to be filed, then the Company shall have the right to defer such filing for a period of not more than ninety
(90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period; provided further that during such ninety
(90) day period, the Company shall not file any registration statement pertaining to the public offering of any securities of the Company. 

(e) Expenses. The Company shall pay all expenses (excluding only underwriting discounts and commissions relating to the Registrable
Securities sold by the Holders) incurred in connection with any registration pursuant to this Section 2 of Exhibit C, including all U.S. federal, “blue sky” and all foreign registration, filing and qualification fees, printer’s
and accounting fees, the fees and expenses (including disbursements) of outside counsels for the Holders and any fee charged by any depositary bank, transfer agent or share registrar. Each Holder participating in a registration pursuant to this
Section 2 of Exhibit C shall bear such Holder’s proportionate share (based on the total number of shares of Registrable Securities sold in such registration other than for the account of the Company) of all discounts and commissions
relating to the Registrable Securities sold by the Holders. Notwithstanding the foregoing, the Company shall not be required to pay any expense of any registration proceeding begun pursuant to this Section 2 of Exhibit C if the registration
request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered, unless the Holders of a majority of the Registrable Securities then outstanding agree that such registration constitutes
the use by the Holders of one (1) demand registration pursuant to this Section 2 of Exhibit C (in which case such registration shall also constitute the use by all Holders of Registrable Securities of one (l) such demand
registration); provided further, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of
their request for such registration and have withdrawn their request for registration with reasonable promptness after learning of such material adverse change, or if the registration proceeding is terminated for any reason not specifically covered
by this Section 2(e), then the Company shall be required to pay all of such expenses and such registration shall not constitute the use of a demand registration pursuant to this Section 2 of Exhibit C. 

  
 Exhibit C 

 3. Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing
at least thirty (30) days prior to filing of any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including registration statements relating to secondary offerings
of securities of the Company, but excluding registration statements relating to any registration under Section 2 of Exhibit C or Section 4 of Exhibit C of this Agreement or to any employee benefit plan or a corporate reorganization) and
will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the
Registrable Securities held by such Holder shall within ten (10) Business Days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of
Registrable Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set
forth herein. 
 (a) Underwriting. If a registration statement under which the Company gives notice under this Section 3 of
Exhibit C is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable Securities to be included in a registration pursuant to this
Section 3 of Exhibit C shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to
distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected by the Company for such underwriting. Notwithstanding any other
provision of this Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares from the registration
and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first to the Company, and second, to each of the Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro-rata basis based on the total number of Registrable Securities then held by each such Holder; provided, however, that the right of the
underwriter(s) to exclude shares (including Registrable Securities) from the registration and underwriting as described above shall be restricted so that (i) the number of Registrable Securities included in any such registration is not reduced
below twenty-five percent (25%) of the aggregate number of Registrable Securities for which inclusion has been requested, even if this will cause the Company to reduce the number of shares it wishes to offer; and (ii) all shares that are not
Registrable Securities and are held by any other Person, including any Person who is an employee, officer or director of the Company or any Subsidiary of the Company shall first be excluded from such registration and underwriting before any
Registrable Securities are so excluded. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by delivering a written notice to the Company and the underwriter(s) at least ten (10) Business
Days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder that is a partnership, the Holder and the
partners and retired partners of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing Persons, and for any Holder that is a corporation, the Holder and all
corporations that are affiliates of such Holder, shall be deemed to be a single “Holder,” and any pro-rata reduction with respect to such “Holder” shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 

  
 Exhibit C 

 (b) Expenses. The Company shall pay all expenses (excluding only underwriting and
brokers’ discounts and commissions relating to shares sold by the Holders) incurred in connection with a registration pursuant to this Section 3 of Exhibit C, including all U.S. federal, “blue sky” and all foreign registration,
filing and qualification fees, printers’ and accounting fees, the fees and expenses (including disbursements) of outside counsels for the Holders and any fee charged by any depositary bank, transfer agent or share registrar. For the avoidance
of doubt, the Company shall pay all expenses incurred in connection with a registration pursuant to this Section 3 of Exhibit C notwithstanding the cancellation or delay of the registration proceeding for any reason. 

(c) Not Demand Registration. Registration pursuant to this Section 3 of Exhibit C shall not be deemed to be a demand registration
as described in Section 2 of Exhibit C above. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 3 of Exhibit C. 

4. Form S-3 or Form F-3 Registration. After its initial public offering,
the Company shall use its best efforts to qualify for registration on Form S-3 or Form F-3 or any comparable or successor form promptly and to maintain such
qualification thereafter. If the Company is qualified to use Form S-3 or Form F-3, any Holder or Holders shall have a right to request in writing that the Company effect
a registration on either Form S-3 or Form F-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such
Holder or Holders, and upon receipt of each such request, the Company shall perform the tasks set out in paragraphs (a) and (b) below: 

(a) Notice. Promptly give written notice of the proposed registration and the Holder’s or Holders’ request therefor, and any
related qualification or compliance, to all other Holders of Registrable Securities; and 
 (b) Registration. As soon as practicable,
effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders or Holders’ Registrable Securities as are specified
in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after the date on which the Company
provides the notice contemplated by Section 4(a) of Exhibit C; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 4 of Exhibit C:

 (i) if Form S-3 or Form F-3 becomes unavailable for such
offering by the Holders; 
 (ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in
such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price of less than US$1,000,000 to the public; or 

(iii) if the Company has, within the six (6) month period preceding the date of such request, already effected a registration under the
Securities Act other than a registration from which the Registrable Securities of Holders have been excluded (with respect to all or any portion of the Registrable Securities the Holders requested be included in such registration) pursuant to the
provisions of Section 3(a) of Exhibit C. 

  
 Exhibit C 

 (c) Expenses. The Company shall pay all expenses (excluding only underwriting or
brokers’ discounts and commissions relating to shares sold by the Holders) incurred in connection with each registration requested pursuant to this Section 4 of Exhibit C, including all U.S. federal, “blue sky” and all foreign
registration, filing and qualification fees, printers’ and accounting fees, the fees and expenses (including disbursements) of outside counsels for the Holders and any fee charged by any depositary bank, transfer agent or share registrar. For
the avoidance of doubt, the Company shall pay all expenses incurred in connection with a registration pursuant to this Section 4 of Exhibit C notwithstanding the cancellation or delay of the registration proceeding for any reason. 

(d) Maximum Frequency. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may request
registration of Registrable Securities under this Section 4 of Exhibit C. 
 (e) Deferral. Notwithstanding the foregoing, if the
Company shall furnish to Holders requesting the filing of a registration statement pursuant to this Section 4 of Exhibit C, a certificate signed by the president or chief executive officer of the Company stating that in the good faith judgment
of the Board, it would be materially detrimental to the Company and its shareholders for such Form S-3 or Form F-3 registration statement to be filed, then the Company
shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the initiating Holders; provided, however, that the Company may not utilize this right more than once in any
twelve (12) month period; provided further that during such ninety (90) day period, the Company shall not file any registration statement pertaining to the public offering of any securities of the Company. 

(f) Not Demand Registration. Form S-3 or Form F-3
registrations shall not be deemed to be demand registrations as described in Section 2 of Exhibit C above. 
 (g) Underwriting.
If the requested registration under this Exhibit C is for an underwritten offering, the provisions of Section 2(b) of Exhibit C shall apply. 
 If the
Company fails to perform any of the Company’s obligations set forth above in this Section 4 of Exhibit C relating to a demand registration made pursuant to Section 2 of Exhibit C, such registration shall not constitute the use of a
demand registration under Section 2 of Exhibit C. 
 5. Obligations of the Company. Whenever required to effect the registration of any
Registrable Securities under this Agreement, the Company shall, as soon as practicable: 
 (a) Registration Statement. Prepare and
file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and keep any such registration statement effective for a period of one
(1) year or until the Holder or Holders have completed the distribution described in the registration statement relating thereto, whichever is earlier; 

(b) Amendments and Supplements. Prepare and file with the SEC such amendments and supplements to such registration statement and the
prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement; 

  
 Exhibit C 

 (c) Prospectuses. Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are
included in such registration; 
 (d) Blue Sky. Use its best efforts to register and qualify the securities covered by such
registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify
to do business or to file a general consent to service of process in any such states or jurisdictions; 
 (e) Deposit Agreement. If
the registration relates to an offering of depositary shares or other securities representing Ordinary Shares deposited pursuant to a deposit agreement or similar facility, cause the depositary under such agreement or facility to accept for deposit
under such agreement or facility all Registrable Securities requested by each Holder to be included in such registration in accordance with this Exhibit C. 

(f) Underwriting. In the event of any underwritten public offering, enter into and perform its obligations under an underwriting
agreement in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement; 

(g) Notification. Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus
relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

(h) Opinions and Comfort Letter. Furnish, at the request of any Holder requesting registration of Registrable Securities, on the date
that such Registrable Securities are delivered to the underwriter(s) for sale, if such Registrable Securities are being sold through underwriters, or, if such Registrable Securities are not being sold through underwriters, on the date that the
registration statement with respect to such Registrable Securities becomes effective, (i) opinions, each dated as of such date, of the counsels representing the Company for the purposes of such registration, in form and substance as is
customarily given to underwriters in an underwritten public offering and reasonably satisfactory to Holders representing a majority of the Registrable Securities requested to be registered, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities and (ii) a “comfort letter” dated as of such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering and reasonably satisfactory to Holders representing a majority of the Registrable Securities requested to be registered, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities. 
 6. Furnish Information. It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Sections 2, 3 or 4 of this Exhibit C that the Holders shall furnish to the Company information regarding such Holders, the Registrable Securities held by them and the intended method of disposition of such
Registrable Securities as shall reasonably be required to timely effect the Registration of their Registrable Securities. 

  
 Exhibit C 

 7. Indemnification. In the event any Registrable Securities are included in a registration statement
under Sections 2, 3 or 4 of this Exhibit C: 
 (a) By the Company. To the extent permitted by law, the Company shall indemnify and
hold harmless each Holder and its Affiliates, partners, officers, directors, employee, legal counsel, agent, any underwriter (as determined in the Securities Act) for such Holder and each Person, if any, who Controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other applicable law, insofar as such
losses, claims, damages, or liabilities or actions in respect thereof arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): 

(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or supplements thereto; 
 (ii) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or 
 (iii) any violation
or alleged violation of the Securities Act, the Exchange Act, any federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or other applicable law in connection with the offering covered by
such registration statement; 
 and the Company shall reimburse each such Holder and its Affiliates, partners, officers, directors,
employees, legal counsel, agents, underwriters or controlling Person for any legal or other expenses reasonably incurred by them, in connection with investigating or defending any such loss, claim, damage, liability or action; provided,
however, that the indemnity contained in this Section 7(a) of Exhibit C shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company,
which consent shall not be unreasonably withheld, conditioned or delayed, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, underwriter or controlling Person of such Holder. 

(b) By Selling Shareholders. To the extent permitted by law, each selling Holder, on a several and not joint basis, will indemnify and
hold harmless the Company, each of its directors, each of its officers who have signed the registration statement, each Person, if any, who Controls the Company, any underwriter and any other Holder selling securities under such registration
statement or any of such other Holder’s partners, directors, officers, legal counsel or any Person who Controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint
or several) to which the Company or any such director, officer, legal counsel, controlling Person, underwriter or other such Holder, partner or director, officer or controlling Person of such other Holder may become subject under the Securities Act,
the Exchange Act or other applicable law, insofar as such losses, claims, damages or liabilities or actions in respect thereto arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation
occurs in the Company’s reasonable reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling Person, underwriter or other Holder, partner, officer, director or controlling Person of such other Holder in connection with investigating or defending any such loss,
claim, damage, liability or action: provided, however, that the indemnity contained in this Section 7(b) of Exhibit C shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further that the total amounts payable in indemnity by a Holder under this Section 7(b) of Exhibit C plus any amount
under Section 7(e) of Exhibit C in respect of any Violation shall not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises. 

  
 Exhibit C 

 (c) Notice. Promptly after receipt by an indemnified party under this Section 7
of Exhibit C of notice of the commencement of any action, including any governmental action, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 7 of Exhibit C, deliver to
the indemnifying party a written notice of the commencement thereof (a “Claim Notice”) and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the Parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and
expenses to be paid by the indemnifying party, (i) during the period from the delivery of a Claim Notice until retention of counsel by the indemnifying party; and (ii) if representation of such indemnified party by the counsel retained by
the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver a written notice to the
indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of liability to the indemnified party under this Section 7 of Exhibit C to the extent the indemnifying party is prejudiced
as a result thereof, but the omission to deliver a written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 7 of Exhibit C. 

(d) Defect Eliminated in Final Prospectus. The foregoing indemnity of the Company and Holders are subject to the condition that, insofar
as they relate to any Violation made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement in question becomes effective or the amended prospectus filed with the
SEC pursuant to SEC Rule 424(b) (the “Final Prospectus”), such indemnity shall not inure to the benefit of any Person if a copy of the Final Prospectus was timely furnished to the indemnified party and was not furnished to the
Person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act. 

  
 Exhibit C 

 (e) Contribution. In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any Holder exercising rights under this Agreement, or any controlling Person of any such Holder, makes a claim for indemnification pursuant to this Section 7 of Exhibit C
but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 7 of Exhibit C provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling Holder or any such controlling Person
in circumstances for which indemnification is provided under this Section 7 of Exhibit C; then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such Holder is responsible for the portion represented by the percentage that the public offering price of its Registrable Securities offered by and sold under the registration
statement bears to the public offering price of all securities offered by and sold under such registration statement, and the Company and other selling Holders are responsible for the remaining portion; provided, however, that, in any
such case: (A) no such Holder will be required to contribute any amount in excess of the net proceeds received by such Holder pursuant to such registration statement; and (B) no Person or entity guilty of fraudulent misrepresentation as
defined in Section 11(f) of the Securities Act will be entitled to contribution from any Person or entity who was not guilty of such fraudulent misrepresentation. 

(f) Survival. The obligations of the Company and Holders under this Section 7 of Exhibit C shall survive for six (6) years
after the completion of any offering of Registrable Securities in a registration statement, regardless of the expiration of any statutes of limitation or extensions of such statutes. 

8. Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which may permit the sale
of the Registrable Securities to the public without registration, the Company agrees to: 
 (a) Make and keep public information available,
as those terms are understood and defined in Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to
the general public; 
 (b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the
Securities Act or the Exchange Act, at all times after the effective date of the first registration under the Securities Act filed by the Company; 

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request, (i) a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements, (ii) a copy of the most recent annual,
interim, quarterly or other report of the Company and, (iii) such other reports and documents as a Holder may reasonably request availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration.

 9. Termination of the Company’s Obligations. Notwithstanding the foregoing, the Company shall have no obligations pursuant to Sections 2, 3 or
4 of this Exhibit C with respect to any Registrable Securities proposed to be sold by a Holder in a registered public offering (i) five (5) years after the consummation of a Qualified IPO, or (ii), if, in the opinion of counsel to the Company,
all such Registrable Securities proposed to be sold by a Holder may then be sold under Rule 144 in one transaction without exceeding the volume limitations thereunder. 

  
 Exhibit C 

 10. No Registration Rights to Third Parties. Without the prior written consent of the Holders of more
than fifty percent (50%) of the Registrable Securities then outstanding, the Company covenants and agrees that it shall not grant, or cause or permit to be created, for the benefit of any Person or entity any registration rights of any kind, whether
similar to the demand, “piggyback” or Form S-3 or Form F-3 registration rights described in this Exhibit C, or otherwise, relating to any shares or other
securities of the Company, other than rights that are subordinate to the rights of the Holders hereunder. 
 11. “Market Stand-Off” Agreement. Each Holder hereby agrees that, if and to the extent requested by the lead underwriter of securities of the Company in connection with a registration relating to a specific proposed
public offering (other than a registration on Form S-8 or a related or successor form relating solely to an employee benefit plan or a registration on Form S-4 or a
related or successor form relating solely to a transaction under SEC Rule 145), such Holder will, subject to the following conditions, enter into a lock-up or standoff agreement in customary form (subject to
the following conditions) under which such Holder agrees not to sell or otherwise transfer or dispose of any Registrable Securities or other shares of the Company owned by such Holder as of the date of such registration for up to one hundred eighty
(180) days following the effective date of the related registration statement. The obligations of each Holder under this Section 11 of Exhibit C are subject to the following conditions: (i) the lockup or standoff agreement applies
only to the first registration statement of the Company which covers securities to be sold on its behalf to the public in an underwritten offering, but not to Registrable Securities actually sold pursuant to such registration statement;
(ii) such Holder is satisfied that all directors, officers, and holders of 1% or more of any class of securities of the Company are bound by substantially identical restrictions; (iii) the lockup or standoff agreement provides that if any
securities of the Company are to be excluded or released in whole or part from such restrictions, the underwriter shall so notify each Holder within three (3) days and each Holder shall be excluded or released, in proportionate amounts to the
extent of the exclusion or release with respect to any other holder of Company’s securities, including any director, officer, or holder of 1% or more of any class of securities of the Company subject to such restrictions; and (iv) the
lockup or standoff agreement by its terms permits transfers of Registrable Securities by any Holder to any Affiliate of such Holder during the restricted period, provided that such Affiliate executes a lock-up
or standoff agreement substantively identical to that signed by the transferring Holder. The lock-up or standoff agreement shall expire no later than ninety (90) days after execution by the Holder if no
underwritten public offering has occurred by the date of such execution. The Company may impose a stop-transfer restriction with respect to Registrable Securities that are that are subject to any such lockup or standoff agreement, but shall remove
such restriction immediately upon the expiration or termination of such lockup or standoff agreement. 
 12. Public Offering Rights (Non-U.S. Offerings). If shares of the Company are offered in an underwritten public offering (whether or not a Qualified IPO) outside of the United States for the account of any Ordinary Shareholder or other
shareholders, each Holder shall have the right to include a pro-rata number of shares (based on the number of shares (on an as—converted basis) then held by such Holder and all other shareholders of the
Company selling in such offering) in such offering on terms and conditions no less favorable to the Holders than to any other selling shareholder. 

  
 Exhibit C 

 13. Re-sale Rights. The Company shall use its best efforts to
assist each Holder in the sale or disposition of its Registrable Securities after a Qualified IPO, including the prompt delivery of applicable instruction letters by the Company and legal opinions from the Company’s counsels in forms reasonably
satisfactory to the Holder’s counsel. In the event the Company has depositary receipts listed or traded on any stock exchange or inter-dealer quotation system, the Company shall pay all costs and fees related to such depositary facility,
including conversion fees and maintenance fees for Registrable Securities held by the Holders.
