Company proposes to offer, issue or sell any Additional Equity Securities, the Company shall first make an offering of such Additional Equity Securities to the Eligible Holders (the “Offerees”) and each Offeree shall have a
preemptive right to purchase a Pro Rata Share of all or any part of such Additional Equity Securities in accordance with the following provisions of this Section 4.1. Any Offeree shall be entitled to apportion the right of
first offer hereby granted it among themselves and their Affiliates in such proportions as it deems appropriate. 
  

	 	(a)	 The Company shall deliver a notice, in accordance with the provisions of Section 8.3
hereof (the “Offer Notice”) to the Offerees stating (i) its bona fide intention to issue such Additional Equity Securities, (ii) the number of such Additional Equity Securities to be issued, and (iii) the price and
terms, if any, upon which it proposes to issue such Additional Equity Securities. 


  

	 	(b)	 Within twenty (20) calendar days after the receipt of the Offer Notice, each Offeree may, by written
notification, elect to purchase or obtain, in whole or in part, at the price and on the terms specified in the Offer Notice, up to that portion of such Additional Equity Securities which equals the proportion that the number of Ordinary Shares
(calculated on an as-converted basis assuming conversion of all convertible securities) then held, by such Offeree bears to the total number of Ordinary Shares (calculated on an
as-converted basis assuming conversion of all 



  
 8 














	 	
convertible securities), held by all Shareholders immediately prior to the issuance of Additional Equity Securities (the “Pro Rata Share”). For avoidance of doubt, with respect
to each Ordinary Shareholder holding Preferred Shares, any calculation in respect of its Pro Rata Shares shall be based on and shall be limited to the relevant Preferred Shares held by such Ordinary Shareholder, without considering any Ordinary
Shares held by such Ordinary Shareholder. 

  

	 	(c)	 The Company shall promptly, in writing, inform each Offeree that elects to purchase all of the Pro Rata Shares
available to it (each, a “Fully Exercising Holder”) of any other Offeree’s failure to do likewise. During the ten (10) day-period commencing immediately after receipt of such
information, each Fully Exercising Holder shall be entitled to notify the Company of its desire to purchase more than its Pro Rata Share of the Additional Equity Securities, stating the number of the Additional Equity Securities it proposes to
purchase. If as a result thereof, such oversubscription exceeds the total number of the remaining Additional Equity Securities available for purchase, the oversubscribing Fully Exercising Holder will be cut back by the Company with respect to their
oversubscriptions to that number of remaining Additional Equity Securities equal to the proportion that the number of Registrable Securities (calculated on an as-converted basis and exclusive of the Ordinary
Shares held by the Ordinary Shareholders) then held by such Fully Exercising Holder bears to the total number of Registrable Securities (calculated on an as-converted basis and exclusive of the Ordinary Shares
held by the Ordinary Shareholders) then held by all Fully Exercising Holders who wish to purchase such unsubscribed Additional Equity Securities. 


  

	 	(d)	 If all Additional Equity Securities referred to in the Offer Notice are not elected to be purchased or obtained
as provided in Section 4.1(b) and (c) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 4.1(b) and
(c) hereof, offer the remaining unsubscribed portion of such Additional Equity Securities to identified parties at a price not less than, and upon terms no more favorable to the Offerees than, those specified in the Offer Notice. If the
Company does not enter into an agreement for the sale of the Additional Equity Securities within such period, or if such agreement is not consummated within twenty (20) days of the execution thereof, the right provided hereunder shall be deemed
to be revived and such Additional Equity Securities shall not be offered unless first reoffered to the Offerees in accordance with this Section 4.1. 



 

	4.2	 Termination. 



The provisions of Section 4 shall terminate upon the consummation of a Qualified IPO.

each calendar year only with the prior written consent from at least three (3) Key Investors’ Directors; (b) the Founder in aggregation may Transfer more than 2% of all outstanding and issued Shares of the Company for each calendar
year only with the prior written consent from at least four (4) Key Investors’ Directors (including the consent of the GIC Director). For the avoidance of doubt, this Section 6.1 (b)(i) shall not apply to any
Transfer regarding the Preferred Shares directly and indirectly held by the Founder. 


  

	 	(ii)	 Subject to Section 6.1(b)(i) above, without the prior written consent of at least one-half (1/2) of Key Investors’ Directors of the Company, the Ordinary Shareholders (except for the Founder who shall make a Transfer of his or her Ordinary Shares in accordance with subsection (i) above)
shall not effect any Transfer to any other party. 


  

	 	(c)	 Right of First Offer on Sale of the Preferred Shares. 



 

	 	(i)	 Transfer Notice of the Preferred Shares. 



 

	 	  	 In the event that any of the Investors other than GIC (the “Preferred Shares Transferor”)
receives a bona fide proposal for purchase of Preferred Shares from any person (the “Preferred Shares Transferee”) (the “Proposed 



  
 12 














	 	
Sale”), then within five (5) calendar days of receipt of such offer from the Preferred Shares Transferee, the Preferred Shares Transferor shall provide the Company and the
Founder with written notice of the material terms of the Proposed Sale (the “Sale Notice”) which shall include the identity of the Preferred Shares Transferee and the number and the share price of the transferred Preferred Shares
(the “Transferred Preferred Shares”). 

  

	 	(ii)	 Right of First Offer for the Proposed Sale. 



 

	 	  	 The Company and the Founder (collectively, the “Qualified Purchasers”) shall have the right of
first offer, to purchase any or all of the Transferred Preferred Shares in whole or in part on the same terms and conditions as specified in the Sale Notice (the “Purchase Right”), provided that the Founder’ Purchase Right
hereunder shall be subordinate to the Company’s Purchase Right, and the Founder shall exercise such Purchase Right on pro rata basis. 


  

	 	  	 Subject to the PRC Laws, including without limitation to the SAFE rules and regulations, the Qualified
Purchasers shall, within ten (10) calendar days of receipt of the Sale Notice (the “Purchase Right Exercise Period”) deliver an exercise notice to the Preferred Shares Transferor to exercise its Purchase Right. If the Qualified
Purchasers choose not to exercise or fully exercise its Purchase Right, or fail to exercise its Purchase Right within the Purchase Right Exercise Period, then the Preferred Shares Transferor may sell the remaining Transferred Preferred Shares to a
Preferred Shares Transferee on terms and conditions not more favorable than those specified in the Sale Notice. Thus, the Qualified Purchasers shall have no further rights under this Section 6.1 (c) with respect to the
Proposed Sale. 


  

	 	(iii)	 Any Investor (except for GIC) shall not, without the prior written consent of HAN Yusheng (汉雨生), transfer or dispose of any of its shares to an entity (the “Direct Competitor of the Company”) 1) the business operation and marketing of which in the PRC
is to diagnose oncology genes for early cancer diagnostic, cancer susceptibility, cancer monitoring and provide individualized medication guides for cancer patients by means of next generation gene sequencing (“NGS”); and 2) that
directly competes with Group Companies in the PRC by offering the same or substantially similar products or services that constitute the primary products or services offered by the Group Companies or Pipelines to be offered by the Group Companies.
For the purpose of this Agreement, the term “Pipelines” shall mean new products or services of the Group Companies which are to be launched within one (1) year upon the date herein. 



 

	 	(iv)	 Unless otherwise expressly provided in this Section 6.1(c), the Investors are
entitled to transfer, sell, or otherwise dispose any of their Equity Securities in any manner without any limitation, subject to applicable Laws. Notwithstanding anything contained herein to the contrary, each of the Investors is entitled to
transfer, sell, or otherwise dispose any of its Equity Securities in any manner to any of its Affiliates. 



  
 13 














	 	(d)	 GIC’s Sale of the Preferred Shares. 



 

	 	(i)	 If GIC proposes to transfer any Shares of the Company to a third party other than its Affiliates, GIC shall
provide a list of the prospective transferees to the Company (“List of Transferees”). The Company shall, upon receipt of the List of Transferees, discuss in good faith with GIC and make suggestions to GIC for the purpose of
finalizing the List of Transferees. The final List of Transferees shall be subject to the mutual consent by GIC and the Company, provided that, the Company shall deliver its consent, objection or any proposed amendment (as the case may be) with
respect to the List of Transferees to GIC within five (5) Business Days following the receipt of the List of Transferees. 


  

	 	(ii)	 Notwithstanding anything to the contrary, Section 6.1(d)(i) shall not apply to
(x) a sale pursuant to Section 6.3, or (y) a sale in the event that the Company fails to fulfill its redemption obligations or pay on the date that the related redemption payment were due pursuant to the Articles.



  

	 	(iii)	 Subject to the Section 6.1(d)(i), GIC is entitled to Transfer any of the Equity
Securities in the Company in any manner without any limitation, subject to applicable Laws. Notwithstanding anything contained herein to the contrary, GIC is entitled to Transfer any of the Equity Securities in the Company in any manner to any of
its Affiliates. 


  

	 	(iv)	 For the avoidance of doubt, Section 6.1(c) shall not apply to GIC or its Affiliates
in any event. 


  

	6.2	 Right of First Refusal 



 

	 	(a)	 Proposed Transfer Notice. 



Each Ordinary Shareholder (including its successors and permitted assigns) (a “Transferor”) proposing to make a Transfer (a
“Proposed Transfer”) must deliver a notice (the “Proposed Transfer Notice”) to the Company and the Eligible Holders. Such Proposed Transfer Notice shall contain the material terms and conditions of the Proposed
Transfer, including without limitation a description and the share price of the Shares (the “Transfer Shares”) that such Transferor may propose to transfer, and the identity of the Prospective Transferee. In the event of a conflict
between this Agreement and any other agreement that may have been entered into by a Transferor with the Company that contains a preexisting right of first refusal, the terms of this Agreement shall prevail and the preexisting right of first refusal
shall be deemed satisfied by compliance with this Section 6.2. 
  

	 	(b)	 Grant of Right of First Refusal to the Eligible Holders. 



 

	 	(i)	 Each Eligible Holders shall have the right for a period of twenty-one
(21) days (the “Eligible Holders’ ROFR Exercise Period”) following the 



  
 14 














	 	
Eligible Holders’ receipt of the Proposed Transfer Notice to elect to purchase its respective pro rata share of the Transfer Share at the same price and subject to the same material terms
and conditions as described in the Proposed Transfer Notice (the “Right of First Refusal”). 

  

	 	(ii)	 Each Eligible Holders may exercise such right of first refusal and, thereby, purchase all or any portion of its
pro rata share of the Transfer Share, by notifying the Transferor and the Company in writing, before expiration of the Eligible Holders’ ROFR Exercise Period as to the number of such Transfer Share that it wishes to purchase.



  

	 	(iii)	 Each Eligible Holders’ pro rata share of the Transfer Share shall be a fraction, the numerator of which
shall be the total number of the Shares and other Equity Securities of the Company (calculated on an as converted but otherwise non-diluted basis) owned by such Eligible Holder on the date of the Proposed
Transfer Notice and the denominator of which shall be the total number of the Shares and other Equity Securities of the Company (calculated on an as-converted but otherwise
non-diluted basis) held by all the Eligible Holders on such date (the “ROFR Pro Rata Share”). For the avoidance of doubt, with respect to each Ordinary Shareholder holding Preferred Shares,
any calculation in respect of its ROFR Pro Rata Share shall be based on and shall be limited to the relevant Preferred Shares held by such Ordinary Shareholder, without considering any Ordinary Shares held by such Ordinary Shareholder .



  

	 	(iv)	 If any Eligible Holders elects not to exercise or fully exercise or fails to fully exercise such right of first
refusal pursuant to Section 6.2(b)(ii), the Transferor shall, within five (5) days following the receipt of all the Eligible Holders’ written notices pursuant to Section 6.2(b)(ii) or the
expiration of the Eligible Holders’ ROFR Exercise Period (whichever is earlier), give notice of such election or failure (the “Re-allotment Notice”) to each other Eligible Holders that
elected to purchase its entire pro rata share of the Transfer Share (the “Purchasing Holders”), which notice shall set forth the number of the Transfer Share not purchased by the other Eligible Holders pursuant to
Section 6.2(b)(ii) (such shares, the “Remaining Transfer Share”). The Purchasing Holders shall have a right of re-allotment such that they shall have fifteen
(15) days from the date such Re-allotment Notice was given to elect to increase the number of the Transfer Share they agreed to purchase under Section 6.2(b)(ii). Such right of re-allotment shall be subject to the following conditions: each Purchasing Holder shall first notify the Transferor of its desire to increase the number of the Transfer Share it agreed to purchase under
Section 6.2(b)(ii), stating the number of the additional Transfer Share it proposes to buy (the “Additional Transfer Share”). If, as a result thereof, the total number of Additional Transfer Share the
Purchasing Holders propose to buy exceeds the total number of the Remaining Transfer Share, the Remaining Transfer Share shall be allocated as necessary such that each Purchasing Holder electing to




  
 15 














	 	
purchase the Additional Transfer Share (an “Over-Purchasing Holder”) shall have the right to purchase such number of Additional Transfer Share equal to the product obtained by
multiplying (i) the number of the Remaining Transfer Share by (ii) a fraction, the numerator of which is the number of the Registrable Securities (calculated on an as-converted but otherwise non-diluted basis and exclusive of the Ordinary Shares held by the Ordinary Shareholder ) held by such Over-Purchasing Holder and the denominator of which is the total number of Registrable Securities (calculated on
an as-converted but otherwise non-diluted basis and exclusive of the Ordinary Shares held by the Ordinary Shareholder) held by all Over-Purchasing Holders,
provided that in no event shall an Over-Purchasing Holder be obligated to purchase more than the maximum number of Additional Transfer Share specified in such Over-Purchasing Holder’s written notice. The procedures described in the
preceding sentence shall be repeated until the earlier to occur if (i) there are no Remaining Transfer Share or (ii) the Over-Purchasing Holders do not wish to purchase any additional Remaining Transfer Share. 


 

	 	(v)	 Subject to applicable securities Laws, the Eligible Holders shall be entitled to apportion the Transfer Share
to be purchased among its partners and/or Affiliates upon written notice to the Company and the Transferor. 


  

	 	(vi)	 If an Eligible Holders gives the Transferor notice that it desires to purchase the Transfer Share, then payment
for the Transfer Share to be purchased shall be made by wire transfer in immediately available funds of the appropriate currency, against allotment of such Transfer Share together with an executed instrument of transfer to be purchased at a place
agreed by the Transferor and all the participating Eligible Holders and at the time of the scheduled closing therefor, which shall be no later than forty-five (45) days after the Eligible Holders’ receipt of the Proposed Transfer Notice.



  

	 	(c)	 Notwithstanding the foregoing, in the event that any Ordinary Shareholder (including its successors and
permitted assigns) proposed to make a Proposed Transfer in relation to any Ordinary Share of the Company: 


  

	 	(i)	 The Company shall have the right, prior to any Eligible Holders’ exercise of Right of First Refusal, for a
period of fifteen (15) days (the “Company’s ROFR Exercise Period”) following the receipt of the Proposed Transfer Notice to elect to purchase any or all of such Transfer Shares at the same price and subject to the same
material terms and conditions as described in the Proposed Transfer Notice. 


  

	 	(ii)	 The Company may exercise such right and, thereby, purchase any or all of such Transfer Shares, by notifying the
Transferor in writing, before expiration of the Company’s ROFR Exercise Period, that it wishes to purchase any or all of such Transfer Shares. 



  
 16 














	 	(iii)	 If the Company gives the Transferor notice that it desires to purchase any or all such Transfer Shares, then
payment for such Transfer Shares shall be made by check or wire transfer in immediately available funds of the appropriate currency, against allotment of such Transfer Shares at a place agreed by the Transferor and the Company and at the time of the
scheduled closing therefor, which shall be no later than forty-five (45) days after the Company’s receipt of the Proposed Transfer Notice. 


  

	 	(iv)	 Regardless of any other provision of this Agreement, if the Company declines in writing or fails to exercise or
fully exercise its right of first refusal pursuant to this Section 6.2(c) with respect to such Transfer Shares, then the Transferor shall be under no obligation to transfer the remaining Transfer Shares to the Company
pursuant to this Section 6.2(c) and shall then be required to provide another notice regarding the remaining Transfer Shares which are not purchased by the Company to each Eligible Holder (the “Additional Proposed
Transfer Notice”, together with the Proposed Transfer Notice, the “Transfer Notice”) (which shall contain the same conditions and price for sale of the remaining Transfer Shares as set forth in the Proposed Transfer Notice)
within five (5) days, then each Eligible Holder shall have the right, within the Eligible Holders’ ROFR Exercise Period following the Eligible Holders’ receipt of the Additional Proposed Transfer Notice, to elect to purchase its
respective pro rata share of the Transfer Share at the same price and subject to the same material terms and conditions as described in the Proposed Transfer Notice, and the provisions set forth in this Section 6 shall
apply to Eligible Holder’s exercise of Right of First Refusal mutatis mutandis. 


  

	 	(v)	 For the avoidance of doubt, the Company shall not have any Right of First Refusal in relation to the Ordinary
Shareholder’s Transfer of any Preferred Shares or any shares converted therefrom, in which case Section 6.2 (b) shall apply to such Transfer. 



 

	 	(d)	 Purchase Price. The purchase price for the Transfer Share to be purchased by the Company or the Eligible
Holders exercising their right of first refusal will be the price set forth in the Transfer Notice. If the purchase price in the Transfer Notice includes consideration other than cash, the cash equivalent value of the non-cash consideration will be
as previously determined by the Board (including the affirmative vote of at least one-half (1/2) of Key Investors’ Directors). 



 

	 	(e)	 Rights of Transferor. If the Company or any Eligible Holders exercises its right of first refusal to
purchase the Transfer Share, then, upon the date the notice of such exercise is given by the Company or such Eligible Holders, the Transferor will have no further rights as a holder of such Transfer Share except the right to receive payment for such
Transfer Share from the Company or the Eligible Holders in accordance with the terms of this Agreement, and the Transferor will forthwith cause all certificate(s) evidencing such Transfer Share to be surrendered to the Company or the Eligible
Holders for transfer to the Company or the Eligible Holders, as applicable together with an executed instrument of transfer. 



  
 17 














	 	(f)	 Application of Co-Sale Right. Regardless of any other provision of this Agreement, if any
Eligible Holders declines in writing or fails to exercise its right of first refusal and if there are any Remaining Transfer Share following the procedures provided in Section 6.2(b) and/or
Section 6.2(c), then the Transferor shall give each Eligible Holder a written notice (the “First Refusal Expiration Notice”) specifying that the Eligible Holders have not exercised their right of first
refusal in full and that the Remaining Transfer Share not purchased by the Company and any Eligible Holders pursuant to Section 6.2(b) and/or Section 6.2(c) (the “Unsold Transfer
Share”) shall be subject to the co-sale right of the Co-Sale Holder (as defined in Section 6.3 below) described in
Section 6.3 below, in which case the First Refusal Expiration Notice shall specify (i) the number of the Unsold Transfer Share, (ii) the Co-Sale Pro Rata Portion (as defined
in Section 6.3 below) of the Unsold Transfer Share for the purpose of such co-sale right and (iii) the name of the Co-Sale Eligible
Holder(s) (as defined in Section 6.3 below). For avoidance of any doubt, the co-sale right under Section 6.3 shall not apply to any Eligible Holders that has
successfully purchased any Transfer Share as a result of its exercise of the right of first refusal pursuant to Section 6.2(b). 


  

	6.3	 Right of Co-Sale. 



 

	 	(a)	 If any Transfer Shares subject to a Proposed Transfer are not purchased pursuant to
Section 6.2 above and thereafter are to be sold to a Prospective Transferee (such Transfer Shares, the “Co-Sale Eligible Shares”), each Eligible Holder that has not
exercised its rights under Section 6.2(b) (each an “Co-Sale Eligible Holder”) may elect to exercise its Right of Co-Sale and
participate on a pro-rata basis in the Proposed Transfer on the same terms and conditions specified in the Proposed Transfer Notice. To exercise its Right of Co-Sale,
the Co-Sale Eligible Holder must give the Transferor written notice to that effect within fifteen (15) calendar days (the “Co-Sale Period”) after
the expiration of the Eligible Holders’ ROFR Exercise Period as provided in Section 6.2(b), and upon giving such notice the Co-Sale Eligible Holder shall be deemed to have
effectively exercised the Right of Co-Sale. 


  

	 	(b)	 Each Co-Sale Eligible Holder, by timely exercising its Right of Co-Sale by delivering the written notice provided for above in Section 6.3(a) may include in the Proposed Transfer all or any part of its Shares equal to the product (the “Co-Sale Pro Rata Portion”) obtained by multiplying (i) the aggregate number of Co-Sale Eligible Shares by (ii) a fraction, the numerator of which is the
number of Ordinary Shares owned by such Co-Sale Eligible Holder (calculated on an as-converted basis assuming conversion of all convertible securities) immediately
before consummation of the Proposed Transfer and the denominator of which is the total number of Ordinary Shares owned, in the aggregate, by all Co-Sale Eligible Holders (calculated on an as-converted basis assuming conversion of all convertible securities) immediately prior to the consummation of the Proposed Transfer, plus the number of Ordinary Shares held by the Transferor (calculated on an as-converted basis assuming conversion of all convertible securities). To the extent that one or more of the Co-Sale Eligible Holders exercises such right of participation in
accordance with the terms and conditions set forth herein, the 



  
 18 














	 	
number of Co-Sale Eligible Shares that the Transferor may sell in the Proposed Transfer shall be correspondingly reduced. For the avoidance of doubt, with
respect to each Ordinary Shareholder holding Preferred Shares, any calculation in respect of its Co-Sale Pro Rata Portion shall be based on and shall be limited to the relevant Preferred Shares held by such
Ordinary Shareholder, without considering any Ordinary Shares held by such Ordinary Shareholder . 

  

	 	(c)	 The sale of the Co-Sale Eligible Shares and remaining Transfer Shares
shall occur within twenty-five (25) calendar days from the beginning of the Co-Sale Period (the “Co-Sale Closing”). For avoidance of doubt, the Right of Co-Sale shall not apply with
respect to Transfer Shares sold or to be sold to the Eligible Holders under the Right of First Refusal in Section 6.2. 


  

	 	(d)	 A Co-Sale Eligible Holder shall effect its participation in the
Proposed Transfer by delivering to the Transferor, prior to the Co-Sale Closing, one or more share certificates, together with an executed instrument of transfer to the Prospective Transferee, representing:



  

	 	(i)	 the number of Ordinary Shares that such Eligible Holder elects to include in the Proposed Transfer; or



  

	 	(ii)	 the number of Preferred Shares that are at such time convertible into the number of Ordinary Shares that such
Eligible Holder elects to include in the Proposed Transfer; provided, however, that if the Prospective Transferee objects to the allotment of convertible Preferred Shares in lieu of Ordinary Shares, such Eligible Holder shall first
convert the Preferred Shares into Ordinary Shares and allot Ordinary Shares as provided above. The Company agrees to make any such conversion concurrent with and contingent upon the actual transfer of such shares to the Prospective Transferee.



  

	 	(e)	 The terms and conditions of any sale pursuant to this Section 6.3 will be contained
in, and governed by, a written purchase and sale agreement with customary terms and provisions for such a transaction. 


  

	 	(f)	 Each share certificate a Co-Sale Eligible Holder delivers to the
Transferor pursuant to Section 6.3(d) above will be transferred to the Prospective Transferee against payment therefor and the register of members of the Company shall be updated in consummation of the sale of the Transfer
Shares pursuant to the terms and conditions specified in the Proposed Transfer Notice and the purchase and sale agreement, and the Transferor shall concurrently therewith remit to each Co-Sale Eligible Holder
the portion of the sale proceeds to which such Co-Sale Eligible Holder is entitled by reason of its participation in such sale. If any Prospective Transferee(s) refuse(s) to purchase securities subject to the
Right of Co-Sale from any Co-Sale Eligible Holder exercising its Right of Co-Sale hereunder, no Transferor may sell any Transfer
Shares to such Prospective Transferee(s) unless and until, simultaneously with such sale, such Transferor purchases all securities subject to the Right of Co-Sale from such
Co-Sale Eligible Holder. 



  
 19 














	6.4	 Proposed Transfer—Compliance Period. 



If any Proposed Transfer is not consummated within ninety days (90) days after receipt of the Proposed Transfer Notice by the Company and
the Eligible Holders, the Transferor proposing to make a Proposed Transfer may not sell any Transfer Shares unless such Transferor has complied in full with each provision of this Section 6. The exercise or election not to
exercise any right by any Eligible Holder hereunder shall not adversely affect its right to participate in any other sales of Transfer Shares subject to this Section 6. 

 

	6.5	 Effect of Failure to Comply. 



 

	 	(a)	 Any Proposed Transfer not made in compliance with the requirements of this Agreement (including without
limitation this Section 6) shall be null and void ab initio, shall not be recorded on the books or register of the Company or its transfer agent and shall not be recognized by the Company. Each Party hereto
acknowledges and agrees that any breach of this Agreement would result in substantial harm to the other Parties hereto for which monetary damages alone could not adequately compensate. Therefore, the Parties hereto unconditionally and irrevocably
agree that any non-breaching Party hereto shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific
performance or the rescission of purchases, sales and other transfers of Shares not made in strict compliance with this Agreement). 


  

	 	(b)	 If any Ordinary Shareholder becomes obligated to sell any Shares to the Company under this Agreement and fails
to allot such Shares in accordance with the terms of this Agreement, the Company may, at its option, in addition to all other remedies it may have, send to such Ordinary Shareholder the purchase price for such Shares as is herein specified and
cancel on its books or registers of members the certificate of certificates representing the shares to be sold. 


  

	 	(c)	 If any Ordinary Shareholder purports to sell any Shares in contravention of the Right of Co-Sale (a “Prohibited Transfer”), each Eligible Holder, in addition to such remedies as may be available by Laws, in equity or hereunder, is entitled to require such Transferor to purchase Shares
from the Eligible Holder, as provided below, and such Transferor will be bound by the terms of such option. If a Transferor makes a Prohibited Transfer, each Eligible Holder upon timely exercise of its Right of
Co-Sale under Section 6.3 may require such Transferor to purchase from such Eligible Holder the type and number of Shares that such Eligible Holder would have been entitled to sell to
the Prospective Transferee under Section 6.3 had the Prohibited Transfer been effected pursuant to and in compliance with the terms of Section 6.3. The sale will be made on the same terms and
subject to the same conditions as would have applied had the Transferor not made the Prohibited Transfer, except that the sale (including, without limitation, the delivery of the purchase price) must be made within ninety (90) days after the
Eligible Holder 



  
 20 














	 	
learns of the Prohibited Transfer, as opposed to the timeframe prescribed in Section 6.3. Such Transferor shall also reimburse such Eligible Holder for any and all fees
and expenses, including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of such Investor’s Right of Co-sale under Section 6.3.


  

	6.6	 Exempted Transfers. 



 

	 	(a)	 Notwithstanding the foregoing or anything to the contrary herein, the provisions of
Section 6.2 and Section 6.3 shall not apply: (i) to a repurchase of Shares from a Transferor by the Company at a price no greater than that originally paid by such Transferor for such Shares
and pursuant to an agreement containing vesting and/or repurchase provisions approved by the Board, (ii) in the case of a Transferor that is a natural person, upon a transfer of Shares by such Transferor, either during his or her lifetime or on
death by will or intestacy, to his or her Immediate Family Members or any other relatives approved by the Board (including the affirmative votes of 1/2 Key Investors’ Directors), or any custodian or trustee for the account of a Transferor or a
Transferor’s Immediate Family Members, (iii) any transfer of shares of the Company indirectly held by any Key Holder from the Holding Entity to such Key Holder at cost, or (iv) the sale of any Shares to the public in a Qualified IPO,
provided that (a) adequate documentation therefor is provided to the Investors and that any such Permitted Transferee agrees in writing to be bound by this Agreement in place of the relevant transferor by executing an Adherence Agreement
substantially in the form attached hereto as Exhibit A (“Adherence Agreement”); and (b) such Transfer is effected in compliance with all applicable Laws including, without limitation, Circular 37 provided however,
without prejudice to the compliance with other applicable Laws, the Transfer of Shares to any custodian or trustee for the account of (x) a Transferor, (y) a Transferor’s Immediate Family Members or (z) a Transferor’s other
relatives approved by the Board (including the affirmative votes of 1/2 Key Investors’ Directors), as set out in sub-section (ii) above, shall be effected in compliance with Circular 37 only to the
extent legally practicable; provided, further, such transferor shall remain liable for any breach by such Permitted Transferee of any provision hereunder. 



 

	 	(b)	 In the event that the Company is to alter or dissolve the existing Captive Structure, each of the Investors,
severally but not jointly, shall be entitled to transfer any and all Equity Securities in the Company then held by the Investors respectively to an Affiliate, Affiliate Fund or a third party designated by the Investors respectively (each as an
“Investor’s Designated Party”) at a price solely decided by the Investors respectively, or swap its Equity Securities in the Company with new Equity Securities denominated in RMB to be issued by any of the surviving Group
Companies to Investor’s Designated Party. As a result, the Investor’s Designated Party shall hold an equity interest in the surviving Group Companies equivalent to the Equity Securities then held by the Investors respectively in the
Company. The Parties shall vote, and cause their respective directors or representatives to vote in favor of such share transfer, and cause the Company and the Group Companies to take all necessary actions to obtain consents and approvals from
competent 



  
 21 














	 	
agencies, if any, to make registration of the share transfer, and to issue new shares, if applicable. If there is any tax or charge arising from such transfer and/or swap of Equity Securities,
the Parties shall consult in good faith to work out an amicable solution. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Sections 6.1, 6.2, 6.3, 6.4 and 6.5 shall not apply in
the case of a transfer or swap in accordance with this Section 6.6(b). 

  

	6.7	 Assignment. Notwithstanding anything herein to the contrary: 



 

	 	(a)	 Assignment and Transfer. The terms and conditions of this Agreement shall inure to the benefit of
and be binding on the respective transferees, successors and/or assigns of the parties hereto. This Agreement is not assignable except in connection with a Transfer of Shares of the Company by a Shareholder in accordance with this Agreement but only
to the extent of such Transfer, provided that (i) any such transferee shall execute and deliver to the Company and the other parties hereto the Adherence Agreement as provided in Section 6.6(a), and
(ii) the Company is given a written notice at the time of such assignment stating the name and address of the assignee, provided further that any right of any Investor under this Agreement are fully assignable to its Affiliates and Affiliates
Fund without the consent of the other parties hereto. 


  

	 	(b)	 Adherence Agreement. For any transfer of Shares to be deemed effective, the transferee shall assume the
obligations of the transferor under this Agreement by executing and delivering to the Company an Adherence Agreement. Upon the execution and delivery of an Adherence Agreement by any transferee, such transferee shall be deemed to be an Ordinary
Shareholder, Investor, Founder or Key Holder hereunder, as appropriate. 


  

	6.8	 Term. 



The provisions of this Section 6 shall terminate upon the consummation of a Qualified IPO. 

 

	7.	 ADDITIONAL COVENANTS.  



 

	7.1	 Protective Provisions. 



 

	 	(a)	 Matters Requiring the Approval of the Investors. 



In addition to any other vote or consent required elsewhere in this Agreement, the Articles or by any applicable statute, each of the Company
and any other Group Companies hereby covenants and agrees with the Investors that it shall not and the Key Holders shall procure that each Group Company does not, either directly or indirectly, by amendment, waiver, merger, consolidation, scheme of
arrangement, amalgamation or otherwise, take, permit to occur, approve, authorize or agree or commit to do (substituting references to “Company” with “Group Company” in the provisions and defined terms below as the context
requires) any of the following actions (whether in a single transaction or a series of related transactions) without the prior affirmative approval or consent of the Majority Preferred Shares Holders.


  
 22 













 
In relation to Section 7.1(a), where any act listed in clauses (i) through (xiv) below requires a Special Resolution of the Members as defined in the Articles where
a general meeting of Members is convened and the consent referred to above is not obtained, each holder of the Preferred Shares who votes against the resolution shall be deemed to have ten (10) times the number of votes of all members who vote
for the resolution:

	 	(iv)	 any purchase, repurchase, redemption or retirement of any Equity Securities (excluding shares repurchased upon
termination of an employee or consultant pursuant to a restricted share purchase agreement or employee incentive plan);

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 for such underwriting. 



 

	 	(b)	 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, second, to each of the Investors requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of shares
of Registrable Securities then held by each such Investor, third, to the other Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of shares of Registrable
Securities then held by each such Holder and fourth, to holders of other securities of the Company; 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 thirty percent (30%) of the aggregate number of shares of Registrable Securities for which inclusion
has been requested; and (ii) all shares that are not Registrable Securities and are held by any other person, including, without limitation, 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, unless otherwise approved by the holders of a majority of the Registrable Securities. If any Holder disapproves of the terms of
any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter(s), 



  
 APPENDIX B--4 














	 	
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. 

  

	3.3	 Not Demand Registration. 



Registration pursuant to this Section 3 shall not be deemed to be a demand registration as described in
Section 2 above. There shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 3. 

 

	4.	 Form F-3 Registration. 



In case the Company shall receive from any Holder or Holders a written request or requests that the Company effect a registration on Form F-3 (or an equivalent registration in a jurisdiction outside of the United States) and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or
Holders, then the Company will: 
  

	4.1	 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 
  

	4.2	 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 Company provides the notice contemplated by Section 4.1; provided, however, that the Company shall not be obligated
to effect any such registration, qualification or compliance pursuant to this Section 4: 
  

	 	(a)	 if Form F-3 is not available for such offering by the Holders;



  

	 	(b)	 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 to the public of less than US$500,000; 



  
 APPENDIX B--5 














	 	(c)	 if the Company shall furnish to the Holders a certificate signed by the president or chief executive officer of
the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be materially detrimental to the Company and its shareholders for such Form F-3 Registration to be
effected at such time, in which event the Company shall have the right to defer the filing of the Form F-3 registration statement no more than once during any twelve (12) month period for a period of not
more than sixty (60) days after receipt of the request of the Holder or Holders under this Section 4; provided that the Company shall not register any of its other shares during such sixty (60) day period.



  

	 	(d)	 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 Sections 2.2 and 3.2; or 


  

	 	(e)	 in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a
general consent to service of process in effecting such registration, qualification or compliance. 


  

	4.3	 Not a Demand Registration. 



Form F-3 registrations shall not be deemed to be demand registrations as described in
Section 2 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 4. 

 

	4.4	 Underwriting. 



If the Holders of Registrable Securities requesting registration under this Section 4 intend to distribute the
Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.2 shall apply to such registration. 
  

	5.	 Expenses.  



All Registration Expenses incurred in connection with any registration pursuant to Sections 2, 3 or 4 (but excluding
Selling Expenses) shall be borne by the Company. Each Holder participating in a registration pursuant to Sections 2, 3 or 4 shall bear such Holder’s proportionate share (based on the total number of shares sold in such
registration other than for the account of the Company) of all Selling Expenses or other amounts payable to 

  
 APPENDIX B--6 













 
underwriter(s) or brokers, in connection with such offering by the Holders. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding
begun pursuant to Section 2 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 Section 2 (in which case such registration shall also constitute the
use by all Holders of Registrable Securities of one (1) 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, then the Holders shall not be
required to pay any of such expenses and such registration shall not constitute the use of a demand registration pursuant to Section 2. 
  

	6.	 Obligations of the Company. 



Whenever required to effect the registration of any Registrable Securities under this Agreement the Company shall, as expeditiously as
reasonably possible: 
  

	6.1	 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, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to ninety (90) days or, in the
case of Registrable Securities registered under Form F-3 in accordance with Rule 415 under the Securities Act or a successor rule, until the distribution contemplated in the registration statement has been
completed; provided, however, that (i) such ninety (90) day period shall be extended for a period of time equal to the period any Holder refrains from selling any securities included in such registration at the request of the
underwriter(s), and (ii) in the case of any registration of Registrable Securities on Form F-3 which are intended to be offered on a continuous or delayed basis, such ninety (90) day period shall be
extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold. 
  

	6.2	 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 securities covered by such registration statement. 

  
 APPENDIX B--7 














	6.3	 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. 

 

	6.4	 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 unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act. 
  

	6.5	 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. 
  

	6.6	 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 (i) the issuance of any stop order by the SEC in respect of such registration statement, or (ii) 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.

  

	6.7	 Opinion 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 securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such


  
 APPENDIX B--8 













 
securities becomes effective, (i) an opinion, dated as of such date, of the counsel 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 a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and (ii) letters dated as of (1) the effective
date of the registration statement covering such Registrable Securities and (2) the closing date of the offering 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 a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities. 
  

	7.	 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 that
the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to timely effect the Registration of their
Registrable Securities. 
  

	8.	 Indemnification. 



In the event any Registrable Securities are included in a registration statement under Sections 2, 3 or 4: 

 

	8.1	 By the Company. 



To the extent permitted by law and its memorandum and articles of association as from time to time altered by special resolution, the Company
will indemnify and hold harmless each Holder, its partners, officers, directors, legal counsel, any underwriter (as defined 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 United States federal or state 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”): 

 

	 	(a)	 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; 



  
 APPENDIX B--9 














	 	(b)	 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 


  

	 	(c)	 any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any United States
federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any United States federal or state securities law in connection with the offering covered by such registration statement;



 and the Company will reimburse each such Holder, its partner, officer, director, legal counsel, underwriter or
controlling person for any legal or other expenses reasonably incurred by them, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 8.1 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), 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 or any partner, officer, director, counsel, underwriter or controlling person of such Holder. 

 

	8.2	 By Selling Holders. 



To the extent permitted by law, each selling Holder will, if Registrable Securities held by Holder are included in the securities as to which
such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within
the meaning of the Securities Act, 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 United States federal or state 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 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 

  
 APPENDIX B--10 













 
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 agreement contained in this Section 8.2 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 in no
event shall any indemnity under this Section 8.2 exceed the net proceeds received by such Holder in the registered offering out of which the applicable Violation arises. 

 

	8.3	 Notice. 



Promptly after receipt by an indemnified party under this Section 8 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 indemnified party under this Section 8, deliver to the indemnifying party a written notice of the
commencement thereof 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, 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
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 8 to the extent the
indemnifying party is prejudiced as a result thereof, but the omission to so deliver 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 8. 
  

	8.4	 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
indemnified party makes a claim for indemnification pursuant to this Section 8 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 8 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any indemnified 

  
 APPENDIX B--11 













 
party in circumstances for which indemnification is provided under this Section 8; then, and in each such case, the indemnified party and the indemnifying party 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 a Holder (together with its related persons) 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. The relative fault of the indemnifying Party and of the indemnified Party shall be determined by a court of law by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying Party or by the indemnified Party and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, however, that, in any such case: (A) no Holder will be required to contribute any amount in excess of the net proceeds to such Holder from the sale of all
such Registrable Securities offered and sold by such Holder pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of 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. 
  

	8.5	 Survival. 



The obligations of the Company and Holders under this Section 8 shall survive 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. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of
each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in
respect to such claim or litigation. 
  

	9.	 No Registration Rights to Third Parties. 



Without the prior written consent of the Holders of a majority in interest 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
F-3 registration rights described in this Appendix B, or otherwise) relating to any securities of the Company which are senior to, or on a parity with, those granted to the Holders of Registrable
Securities. 

  
 APPENDIX B--12 














	10.	 Rule 144 Reporting. 



With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of the
Registrable Securities to the public without registration or pursuant to a registration on Form F-3, after such time as a public market exists for the Ordinary Shares, the Company agrees to: 

 

	10.1	 Make and keep public information available, as those terms are understood and defined in Rule 144 under the
Securities Act, at all times after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 



 

	10.2	 File with the SEC in a timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 


  

	10.3	 So long as a Holder owns any Registrable Securities, to furnish to such Holder forthwith upon request
(i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the Company’s initial public offering), the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting requirements), or its qualification as a registrant whose securities may be resold pursuant to Form F-3 (at any time after it so
qualifies), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the SEC that
permits the selling of any such securities without registration or pursuant to Form F-3. 


  

	11.	 Market Stand-Off. 



Each Shareholder agrees that, so long as it holds any voting securities of the Company, upon request by the Company or the underwriters
managing the initial public offering of the Company’s securities, it will not sell or otherwise transfer or dispose of an interest in any shares of the Ordinary Shares of the Company (other than those permitted to be included in the
registration and other transfers to Affiliates permitted by law) without the prior written consent of the Company or such underwriters, as the case may be, for a period of time specified by the representative of the underwriters not to exceed one
hundred and eighty (180) days from the effective date of the registration statement covering such initial public offering or the pricing date of such offering as may be requested by the underwriters; provided that (a) the forgoing
provisions of this Section shall not apply to the sale of any securities of the Company to an underwriter pursuant to any underwriting agreement, and shall not be applicable to any Holder unless all directors, officers and all other holders of at
least one percent (1%) of the outstanding share capital of the Company (calculated on an as converted to Ordinary Share basis) must be bound by restrictions at least as restrictive 

  
 APPENDIX B--13 













 
as those applicable to any such Holder pursuant to this Section, (b) this Section shall not apply to a Holder in whole or in part to the extent that any other Person subject to substantially
similar restrictions is released in whole or in part, and (c) to the extent not otherwise objected by the underwriters, the lockup agreements shall permit a Holder to transfer its Registrable Securities to its Affiliates so long as the
transferees enter into the same lockup agreement. The Investors agree to execute and deliver to the underwriters a lock-up agreement containing substantially similar terms and conditions as those contained
herein. In order to enforce the foregoing covenant, the Company may place restrictive legends on the certificates and impose stop-transfer instructions with respect to the Registrable Securities of each shareholder (and the shares or securities of
every other Person subject to the foregoing restriction) until the end of such period.
