9. Subject to the provisions of these Articles, any resolution of the Members and any agreement which is binding on the Company to the contrary, the unissued shares of the Company shall be at the disposal of the directors who may, without limiting or affecting any rights previously conferred on the holders of any existing shares or class or series of shares, offer, allot, grant options over or otherwise dispose of shares to such persons, at such times and upon such terms and conditions as the Company may by resolution of directors determine provided that no share shall be issued at a discount except in accordance with the Law.

The consideration in respect of the shares constitutes capital to the extent of thereof and the excess constitutes share premium.

12. A share issued by the Company upon conversion of, or in exchange for, another share or a debt obligation or other security in the Company, shall be treated for all purposes as having been issued for money equal to the consideration received or deemed to have been received by the Company in respect of the other share, debt obligation or security.

16. Subject to receipt of all approvals required under the Memorandum or elsewhere in these Articles, the Company may purchase, redeem or otherwise acquire and hold its own shares but in accordance with the Law and the Company be and is hereby authorised to make payment out of capital in connection therewith.

6

17. Subject to provisions to the contrary in

(a) the Memorandum or these Articles;

(b) the designations, powers, preferences, rights, qualifications, limitations and restrictions with which the shares were issued; or

(c) the subscription agreement for the issue of the shares,

the Company may not purchase or redeem its own shares without the consent of members whose shares are to be purchased or redeemed.

19. Shares that the Company purchases, redeems or otherwise acquires pursuant to the preceding paragraph shall be cancelled and available for re-issue thereafter.

TRANSFER OF SHARES

20. Subject to any limitations in the Memorandum, registered shares in the Company may be transferred by a written instrument of transfer signed by the transferor and containing the name and address of the transferee, but in the absence of such written instrument of transfer the directors may accept such evidence of a transfer of shares as they consider appropriate.

21. The Company shall not be required to treat a transferee of a registered share in the Company as a member until the transferee’s name has been entered in the Register of Members.

If the directors refuse to register a transfer they shall notify the transferee within sixty (60) days of such refusal.

VARIATION OF CLASS RIGHTS

23. If at any time the authorized capital is designated into different classes or series of shares, subject to compliance with other consent or approval requirements under these Articles, the rights attached to any class or series (unless otherwise provided by the terms of issuance of the shares of that class or series) may, whether or not the Company is being wound up, be varied with the consent in writing of the holders of at least fifty percent (50%) of the issued shares of that class or series, which may be affected by such variation.

24. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not be deemed to be varied by the creation or issuance of further shares ranking pari passu therewith.

TRANSMISSION OF SHARES

25. The executor or administrator of a deceased member, the guardian of an incompetent member or the trustee of a bankrupt member shall be the only person recognized by the Company as having any title to his share but they shall not be entitled to exercise any rights as a member of the Company until they have proceeded as set forth in the next following three regulations.

7

26. The production to the Company of any document which is evidence of probate of the will, or letters of administration of the estate, or confirmation as executor, of a deceased member or of the appointment of a guardian of an incompetent member or the trustee of a bankrupt member shall be accepted by the Company even if the deceased, incompetent or bankrupt member is domiciled outside the Cayman Islands if the document evidencing the grant of probate or letters of administration, confirmation as executor, appointment as guardian or trustee in bankruptcy is issued by a foreign court which had competent jurisdiction in the matter. For the purpose of establishing whether or not a foreign court had competent jurisdiction in such a matter the directors may obtain appropriate legal advice. The directors may also require an indemnity to be given by the executor, administrator, guardian or trustee in bankruptcy.

27. Any person becoming entitled by operation of law or otherwise to a share or shares in consequence of the death, incompetence or bankruptcy of any member may be registered as a member upon such evidence being produced as may reasonably be required by the directors. An application by any such person to be registered as a member shall for all purposes be deemed to be a transfer of shares of the deceased, incompetent or bankrupt member and the directors shall treat it as such.

28. Any person who has become entitled to a share or shares in consequence of the death, incompetence or bankruptcy of any member may, instead of being registered himself, request in writing that some person to be named by him be registered as the transferee of such share or shares and such request shall likewise be treated as if it were a transfer.

29. What amounts to incompetence on the part of a person is a matter to be determined by the court having regard to all the relevant evidence and the circumstances of the case.

REDUCTION OR INCREASE IN AUTHORIZED CAPITAL OR CAPITAL

30. Subject to the Law, the Company may from time to time by a Special Resolution alter the conditions of its Memorandum to increase its share capital by new shares of such amount as it thinks expedient or, if the Company has shares without par value, increase its share capital by such number of shares without nominal or par value, or increase the aggregate consideration for which its shares may be issued, as it thinks expedient.

31. Subject to the Law, the Company may from time to time by a Special Resolution alter the conditions of its Memorandum to:

(a) consolidate and divide all or any of its share capital into shares of larger amount than its existing shares;

(b) subdivide its shares or any of them into shares of an amount smaller than that fixed by the Memorandum; or

(c) cancel shares which at the date of the passing of the resolution have not been taken or agreed to be taken by any person, and diminish the amount of its share capital by the amount of the shares so cancelled or, in the case of shares without par value, diminish the number of shares into which its capital is divided.

32. For the avoidance of doubt, it is declared that Article 31(a) and (b) above do not apply if at any time the shares of the Company have no par value.

33. Subject to the Law, the Company may from time to time by Special Resolution reduce its share capital in any way or, subject to Article 130, alter any conditions of the Memorandum relating to share capital.

8

34.

The holders of Ordinary Shares, subject to provisions of these Articles, shall:

(a) be entitled to one vote per share;

(b) be entitled to such dividends as the Board may from time to time declare;

(c) in the event of a winding-up or dissolution of the Company, whether voluntary or involuntary or for the purpose of a reorganization or otherwise or upon any distribution of capital, be entitled to the surplus assets of the Company; and

(d) generally be entitled to enjoy all of the rights attaching to shares.

The Investors shall be entitled to the rights set out in the following Articles.

CONVERSION OF PREFERRED SHARES

35. Conversion Rights. Unless converted earlier pursuant to Article 36 below, each holder of Preferred Shares shall have the right, at such holder’s sole discretion, to convert all or any portion of the Preferred Shares into Ordinary Shares at any time.

The conversion rate for Preferred Shares shall be determined by dividing the applicable Deemed issue price by the conversion price then in effect at the date of the conversion. The initial conversion price at which Ordinary Shares shall be issued upon conversion of the applicable Preferred Shares will be the Deemed issue price (i.e., a 1-to-1 initial conversion ratio), which will be subject to adjustments to reflect share dividends, share splits and other events, as provided in Article 39 below (the “Preferred Share Conversion Price”).

Nothing in this Article 35 shall limit the automatic conversion rights of Preferred Shares described in Article 36 below.

36. Automatic Conversion. Each Preferred Share shall automatically be converted into Ordinary Shares, at the then applicable Preferred Share Conversion Price upon the closing of a Qualified IPO (as defined in the Shareholders Agreement) (or before the closing of a Qualified IPO, if such conversion is necessary or desirable for complying with any law, regulation or rule applicable to the Qualified IPO (including any applicable listing rules, listing decisions and guidance letters published or issued by the relevant recognized international securities exchange). In the event of the automatic conversion of the Preferred Shares upon a Qualified IPO as aforesaid, the person(s) entitled to receive the Ordinary Shares issuable upon such conversion of Preferred Shares shall not be deemed to have converted such Preferred Shares until immediately prior to time specified above.

37. Mechanics of Conversion. No fractional Ordinary Share shall be issued upon conversion of the Preferred Shares. In lieu of any fractional shares to which the holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the then effective Preferred Share Conversion Price. Before any holder of Preferred Shares shall be entitled to convert the same into full Ordinary Shares and to receive certificates therefor, he shall surrender the certificate or certificates therefor, at the office of the Company or of any transfer agent for the Preferred Shares and shall give written notice to the Company at such office that he elects to convert the same. The Company shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Shares a certificate or certificates for the number of Ordinary Shares to which he shall be entitled as aforesaid and a check payable to the holder in the amount of any cash amounts payable as the result of a conversion into fractional Ordinary Shares, if any. Such conversion shall be deemed to have been made immediately prior to close of business on the date of receipt by the Company of the share certificate in respect of the Preferred Shares to be converted, and the person or persons entitled to receive the Ordinary Shares issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Ordinary Shares on such date after its name is recorded in the Register of Members as the holder of such Ordinary Shares. The Directors may effect conversion in any matter permitted by law including, without prejudice to the generality of the foregoing, repurchasing or redeeming the relevant Preferred Shares and applying the proceeds towards the issue of the relevant number of new Ordinary Shares.

9

38. Reservation of Shares Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but unissued Ordinary Shares solely for the purpose of effecting the conversion of the shares of the Preferred Shares such number of its Ordinary Shares as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Preferred Shares, and if at any time the number of authorized but unissued Ordinary shares shall not be sufficient to effect the conversion of all then outstanding shares of the Preferred Shares, in addition to such other remedies as shall be available to the holder of such Preferred Shares, the Company will take such corporate action as may, in the opinion of its legal counsel, be necessary to increase its authorized but unissued Ordinary Shares to such number of shares as shall be sufficient for such purposes.

ADJUSTMENTS TO CONVERSION PRICE

39. (a) Special Definitions. For purposes of this Article 39, the following definitions shall apply:

(i) “Options” mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Ordinary Shares or Convertible Securities.

(ii) “Convertible Securities” shall mean any evidences of indebtedness, shares (other than the Preferred Shares and Ordinary Shares) or other securities directly or indirectly convertible into or exchangeable for Ordinary Shares.

(E) any securities issued pursuant to a Qualified IPO or for the adjustment pursuant to Article 39(e) below.

10

(b) No Adjustment to Conversion Price.

(c) Deemed Issuance of Additional Ordinary Shares. In the event the Company at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number that would result in an adjustment pursuant to clause (ii) below) of Ordinary Shares issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Ordinary Shares issued as of the time of such issuance or, in case such a record date shall have been fixed, as of the close of business on such record date, provided that Additional Ordinary Shares shall not be deemed to have been issued with respect to Preferred Shares, unless the consideration per share (determined pursuant to Article 39(f) hereof) of such Additional Ordinary Share would be less than the Preferred Share Conversion Price in effect on the date of and immediately prior to such issuance, or such record date, as the case may be, and provided further that in any such case in which Additional Ordinary Shares are deemed to be issued:

(i) no further adjustment to the Preferred Share Conversion Price shall be made upon the subsequent issuance of Convertible Securities or Ordinary Shares upon the exercise of such Options or conversion or exchange of such Convertible Securities;

(ii) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Company, or increase or decrease in the number of Ordinary Shares issuable, upon the exercise, conversion or exchange thereof, the Preferred Share Conversion Price computed upon the original issuance thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

(iii) upon the expiration of any such Options or any rights of conversion or exchange under such Convertible Securities which shall not have been fully exercised, the Preferred Share Conversion Price computed upon the original issuance thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration be recomputed as if:

(A) in the case of Convertible Securities or Options for Ordinary Shares, the only Additional Ordinary Shares issued were Ordinary Shares, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Company for the issuance of all such Options, whether or not exercised, plus the consideration actually received by the Company upon such exercise, or for the issuance of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Company upon such conversion or exchange, and

11

(B) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issuance of such Options, and the consideration received by the Company for the Additional Ordinary Shares deemed to have been then issued was the consideration actually received by the Company for the issuance of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Company upon the issuance of the Convertible Securities with respect to which such Options were actually exercised;

(iv) no readjustment pursuant to clause (ii) or (iii) above shall have the effect of increasing the Preferred Share Conversion Price to an amount which exceeds the lower of (i) the Preferred Share Conversion Price immediately prior to the original adjustment date, or (ii) the Preferred Share Conversion Price that would have resulted from any issuance of Additional Ordinary Shares between the original adjustment date and such readjustment date; and

(v) in the case of any Options which expire by their terms not more than 30 days after the date of issuance thereof, no adjustment of the Preferred Share Conversion Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the manner provided in clause (iii) above.

(d) Adjustment of Preferred Share Conversion Price upon Issuance of Additional Ordinary Shares below the Preferred Share Conversion Price. In the event that the Company shall issue any Additional Ordinary Shares (including those deemed to be issued pursuant to Article 39 (c)) without consideration or at a subscription price per Ordinary Share (on an as-converted basis) (the “New Issuance Price”)

(i) less than the Preferred Share Conversion Price of any of the Preferred Shares (excluding the Series D Preferred Shares) in effect on the date of and immediately prior to such issuance, then the Preferred Share Conversion Price for such Preferred Shares (excluding the Series D Preferred Shares) shall forthwith be reduced, concurrently with such issuance of the Additional Ordinary Shares, to a price determined as set forth below:

CP2 = CP1 * (A + B) / (A + C)

For the purposes of the foregoing formula, the following definitions shall apply:

(A) “CP2” shall mean the applicable Conversion Price for such Preferred Shares (excluding the Series D Preferred Shares) in effect immediately after such issuance;

(B) “CP1” shall mean the applicable Conversion Price for such Preferred Shares (excluding the Series D Preferred Shares) in effect immediately prior to such issuance;

(C) “A” shall mean the number of Ordinary Shares outstanding immediately prior to such issuance on a fully diluted and as converted basis (assuming the conversion of all outstanding Convertible Securities and the exercise of all outstanding Options);

(D) “B” shall mean the number of Ordinary Shares that would have been issued or deemed issued if such issuance of the Additional Ordinary Shares had been made at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the Company in respect of such issuance by CP1); and

(E) “C” shall mean the number of Additional Ordinary Shares issued in such issuance.

12

(ii) less than the applicable Preferred Share Conversion Price of the Series D Preferred Shares in effect on the date of and immediately prior to such issuance, then the applicable Preferred Share Conversion Price of the Series D Preferred Shares shall be reduced, concurrently with such issuance of the Additional Ordinary Shares, to the New Issuance Price.

(e) Adjustment of Series D Preferred Share Conversion Price upon Failure to Obtain a Qualified IPO. In the event that the Company undertakes an IPO other than a Qualified IPO or any IPO takes place after March 31, 2022 (each, an “Unqualified IPO”), then the Preferred Share Conversion Price for each Series D Share shall forthwith be reduced, concurrently with the issuance of the Additional Ordinary Shares under the Unqualified IPO, to a price being the lower of the following, provided that such adjusted price calculated through the following formula is lower than the Series D Issue Price:

(i) AP= 85% * P; and

(ii) AP= P / (1 + 15%)^N

“AP” shall mean the adjusted Conversion Price;

“P” shall mean the per share price under the Unqualified IPO;

“N” shall mean a fraction, the numerator of which is the number of calendar days between the Series D Issue Date and the date of the Unqualified IPO and the denominator of which is 365.

(f) Determination of Consideration. For purposes of this Article 39, the consideration received by the Company for the issuance of any Additional Ordinary Shares shall be computed as follows:

(i) Cash and Property. Except as provided in clause (ii) below, such consideration shall:

(A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Company excluding amounts paid or payable for accrued interest for accrued dividends;

(B) insofar as it consists of property other than cash, be computed at the fair value thereof at the time of such issuance, as determined in good faith by the Board; provided, however, that no value shall be attributed to any services performed by any employee, officer or director of the Company; and

(C) in the event Additional Ordinary Shares are issued together with other shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received with respect to such Additional Ordinary Shares, computed as provided in clauses (A) and (B) above, as determined in good faith by the Board.

13

(ii) Options and Convertible Securities. The consideration per share received by the Company for Additional Ordinary Shares deemed to have been issued pursuant to Article 39(c), relating to Options and Convertible Securities, shall be determined by dividing

(A) the total amount, if any, received or receivable by the Company as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities by

(B) the maximum number of Ordinary Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(g) Adjustments for Share Dividends, Subdivisions, Combinations or Consolidations of Ordinary Shares. In the event the outstanding Ordinary Shares shall be subdivided (by share dividend, share split, or otherwise), into a greater number of Ordinary Shares, the Preferred Share Conversion Price shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding Ordinary Shares shall be combined or consolidated, by reclassification or otherwise, into a lesser number of Ordinary Shares the Preferred Share Conversion Price shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased.

(h) Adjustments for Other Distributions. In the event the Company at any time or from time to time makes, or files a record date for the determination of holders of Ordinary Shares entitled to receive any distribution payable in securities or assets of the Company other than Ordinary Shares, then and in each such event provision shall be made so that the Investors shall receive upon conversion thereof, in addition to the number of Ordinary Shares receivable thereupon, the amount of securities or assets of the Company which they would have received had their Preferred Shares been converted into Ordinary Shares on the date of such event and had they thereafter, during the period from the date of such event to and including the date of conversion, retained such securities or assets receivable by them as aforesaid during such period, subject to all other adjustment called for during such period under this Article 39 with respect to the rights of the holders of the Preferred Shares.

(i) Adjustments for Reclassification, Exchange and Substitution. If the Ordinary Shares issuable upon conversion of the Preferred Shares shall be changed into the same or a different number of shares of any other class or classes of shares, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for above), then and in each such event the holder of each share of Preferred Shares shall have the right thereafter to convert such share into the kind and amount of shares and other securities and property receivable upon such reorganization or reclassification or other change by holders of the number of Ordinary Shares that would have been subject to receipt by the holders upon conversion of the Preferred Shares immediately before that change, all subject to further adjustment as provided herein.

(j) No Impairment. The Company will not, by the amendment of the Memorandum and these Articles or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of Article 39 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the Investors against impairment.

14

(k) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Preferred Share Conversion Price pursuant to Article 39, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred Shares a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any holder of Preferred Shares, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Preferred Share Conversion Price at the time in effect, and (iii) the number of Ordinary Shares and the amount, if any, of other property which at the time would be received upon the conversion of such Preferred Shares.

(l) Miscellaneous.

(i) All calculations under this Article 39 shall be made to the nearest one hundredth (1/100) of a cent or to the nearest one hundredth (1/100) of a share, as the case may be.

(ii) No adjustment in the Preferred Share Conversion Price need be made if such adjustment would result in a change in such conversion price of less than US$0.01. Any adjustment of less than US$0.01 which is not made shall be carried forward and shall be made at the time of and together with any subsequent adjustment which, on a cumulative basis, amounts to an adjustment of US$0.0l or more in such conversion price and in no event shall the adjusted Preferred Share Conversion Price shall fall below the par value of the Ordinary Shares.

VOTING RIGHTS

40. Each Preferred Share shall carry a number of votes equal to the number of Ordinary Shares then issuable upon its conversion into Ordinary Shares at the record date for determination of the shareholders entitled to vote on such matters, or, if no such record date is established, at the date such vote is taken or any written consent of shareholders is solicited. To the extent that applicable law, the Memorandum and/or these Articles require the Preferred Shares to vote separately as a class with respect to any matters, the Preferred Shares shall vote separately as a class with respect to such matters.

CONFLICT OF INTERESTS

96. No agreement or transaction between the Company and one or more of its directors or any person in which any director has a financial interest or to whom any director is related, including as a director of that other person, is void or voidable for this reason only or by reason only that the director is present at the meeting of directors or at the meeting of the committee of directors that approves the agreement or transaction or that the vote or consent of the director is counted for that purpose if the material facts of the interest of each director in the agreement or transaction and his interest in or relationship to any other party to the agreement or transaction are disclosed in good faith or are known by the other directors.

100.

24

101. The termination of any proceedings by any judgment, order, settlement, conviction or the entering of a nolle prosequi does not, by itself, create a presumption that the person did not act honestly and in good faith and with a view to the best interests of the Company or that the person had reasonable cause to believe that his conduct was unlawful.

102. If a person to be indemnified has been successful in defense of any proceedings referred to above the person is entitled to be indemnified against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred by the person in connection with the proceedings.

129. Liquidation Preference.

A. 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:

27

(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;

(b) after distribution or payment in full of the Series D Preference Amount pursuant to Article 129A(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 Event, 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 Group 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 Article 129A(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.

B. Unless otherwise waived in writing by all Preferred Shareholders or provided under Section 5.4 of the Shareholders Agreement, each of an Acquisition (excluding the Drag-Along Sale) shall constitute and be treated as a Liquidation Event under this Article 129, and any proceeds, whether in cash or properties, resulting from any such event shall be distributed in accordance with the terms of this Article 129.

C. 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 Investors and Ordinary Shareholders shall be that as determined in good faith by the Board. Any securities 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 deemed to be 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 actively traded over-the-counter, the value shall be deemed to be 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.

28

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 under the Shareholders Agreement, 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 Article 129, 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.

D. 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 the Shareholders Agreement and these 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.

E. Notwithstanding any other provision of this Article 129, 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.

F. 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 Article 129 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.

G. The provisions under this Article 129 shall be terminated upon the occurrence of a Qualified IPO.

REDEMPTION

130. Redemption by the Company and Founders.

A. 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”):

(a) for each holder of the Preferred Shares, (i) the Company has not consummated a Qualified IPO before March 31, 2022; (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);

29

(b) for VIVO and/or each holder of the Series D Preferred Shares (in addition to its rights under Article 130A(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.

B. 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 this Article 130 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 Article 130 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 Article 130 and shall have paid all the Redemption Price for such Preferred Shares requested to be redeemed payable pursuant to this Article 130.

30

C. 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 this Article 129 above. 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 these Articles, until such time as the Company or the Founder has sufficient legal funds to redeem such Preferred Shares.

D. The provisions under this Article 130 shall be terminated upon the occurrence of a Qualified IPO.
