1. INFORMATION RIGHTS; BOARD REPRESENTATION.

1.1 Information and Inspection Rights. The Company covenants and agrees that for so long as an Investor, together with its Affiliates, holds Shares that represent at least seven percent (7%) of the then outstanding Preferred Shares (as defined below) of the Company (calculated on an as-converted basis) (each, a “Major Investor”), the Company shall deliver to such Major Investor; provided that the Board (as defined below) has not reasonably and in good faith determined that such Major Investor is a competitor of the Group Companies that is primarily engaged in discovering and developing first-in-class and best-in-class innovative Precision Biologics-utilizing platform. (the “Competitor”):

(a) as soon as practicable, but in any event within one hundred twenty (120) days after the end of each fiscal year (or by such later date as may be approved by the Board (as defined below)), audited annual financial statements of the Company, including a consolidated balance sheet of the Company and each Group Company as at the end of such fiscal year and consolidated statements of income and cash flows of the Company and each Group Company for such year, prepared in accordance with United States generally accepted accounting principles as promulgated by the Financial Accounting Standards Board (“US GAAP”);

(b) as soon as practicable, but in any event within forty five (45) days after the end of each of the first three quarters, unaudited quarterly financial statements of the Company for such period, including an unaudited consolidated balance sheet of the Company and each Group Company as at the end of each such quarterly period and unaudited consolidated statements of income and cash flows of the Company and each Group Company for such period and for the current fiscal year to date, prepared in accordance with the US GAAP (except that such financial statements may (i) be subject to normal year-end audit adjustments; and (ii) not contain all notes thereto that may be required in accordance with the US GAAP);

(c) as soon as practicable, but in any event within thirty (30) days after the end of each month, unaudited income statement and statement of cash flows of the Company for such month, prepared in accordance with the US GAAP (except that such financial statements may (i) be subject to normal year-end audit adjustments and (ii) not contain all notes thereto that may be required in accordance with the US GAAP);

(d) as soon as practicable, but in any event not later than thirty (30) days prior to the end of each fiscal year, a comprehensive operating budget forecasting the Company’s revenues, expenses, and cash position on a month-to-month basis for the upcoming fiscal year; and

(e) such other information relating to the financial condition, business or corporate affairs of the Company as such Major Investor may from time to time reasonably request (the above rights, collectively, the “Information Rights”).

For so long as an Investor, together with its Affiliates, holds any Shares, the Company shall deliver to such Investor the financial information set forth in Sections 1.1(a) and 1.1(b) above.

The Company further covenants and agrees that each Major Investor shall have the right to, together with its officers, employees, auditors, legal counsel and other agents, inspect the facilities, records and books of the Group Companies at any time during regular working hours on reasonable prior notice to the Company and the right to discuss the business, operation and conditions of the Group Companies with any Group Company’s directors, officers, employees, accounts, legal counsels and investment bankers (the “Inspection Rights”); provided that the Company shall not be obligated in respect of the Inspection Rights if the Board has reasonably and in good faith determined that such Major Investor is a Competitor and shall have no obligation to grant access to a Major Investor with respect to information which the Board reasonably determines in good faith is (i) highly confidential and the disclosure of which to such Major Investor may result in material harm to the Company or (ii) attorney-client privileged and should not, therefore, be disclosed. Each Major Investor shall, during the normal working hours and by giving the Company a fifteen (15) days prior written notice and at its own expense, have the right to audit the books and records of the Group Companies and the Company shall, and shall cause each other Group Company, to cooperate with any Major Investor and its representatives with respect to any such audit; provided, that any Major Investor requesting such audit shall notify all other Major Investors in writing and the other Major Investors shall have the right to participate in such audit by written notice to the initiating Major Investor (the “Audit Rights”); provided, however, that such Audit Rights shall be exercised by Major Investors no more than once during each fiscal year.

The Information Rights and the Inspection Rights shall terminate (i) immediately before the consummation of the Company’s first underwritten public offering of its Ordinary Shares (as defined below) under the Securities Act (an “IPO”); (ii) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act; or (iii) upon the closing of a Deemed Liquidation Event, as such term is defined in the Restated Articles.

1.2 Board Representation.

(a) The Company. The Amended and Restated Memorandum and Articles of Association of the Company, as amended from time to time (the “Restated Articles”) shall provide that the Company’s board of directors (the “Board”) shall consist of directors appointed or designated in accordance with this Section 1.2, which shall initially be five (5) directors upon the Initial Closing, which composition shall not be changed except pursuant to an amendment to the Restated Articles. Each director shall have one (1) voting right at any Board meeting.

(i) (A) so long as any Investor (together with its Affiliates)

continues to directly or indirectly hold at least ten percent (10%) of the issued and outstanding Ordinary Shares (on an as-converted but non-diluted basis), it shall have the right to appoint and remove one (1) director; and (B) so long as any Investor (together with its Affiliates) continues to directly or indirectly hold at least thirty percent (30%) of the issued and outstanding Ordinary Shares (on an as-converted but non-diluted basis), it shall have the right to appoint and remove one (1) additional director (collectively, “Investor Directors”, and each an “Investor Director”);

(ii) one (1) director shall be the chief executive officer (the “Chief Executive Officer”) of the Company, who shall initially be Xxxx Xxxx; and

(iii) so long as any Investor (together with its Affiliates) is the single largest shareholder of the Company (on an as-converted but non-diluted basis) and continues to directly or indirectly hold more than twenty-five percent (25%) of the issued and outstanding Ordinary Shares (on an as-converted but non-diluted basis), such Investor may designate any member of the Board as chairman of the Board (the “Chairman”), provided that if there is no such Investor, Xxxx Xxxx shall be the Chairman.

(iv) If the number of directors appointed pursuant to Section 1.2(i), (ii) and (iii) is less than five (5), additional independent director(s) may be nominated to fulfill the vacant seats of the Board, provided that such independent directors shall not be employees of any Group Company nor employees of any Investor or its Affiliates, and who shall be nominated by the Board and approved by the Required Holders.

(b) Other Group Companies. Upon written request from any Major Investor, each other Group Company shall ensure that the composition of its board of directors of such other Group Company shall mirror the composition of the Board.

(c) Observer Rights. In the event that any Investor, who is originally entitled to appoint an Investor Director pursuant to Section 1.2(a), (A) is no longer entitled to the right to appoint any Investor Director, but (B) continues to hold at least five percent (5%) of the issued and outstanding Ordinary Shares (on an as-converted basis), such Investor shall have the right to designate one (1) non-voting observer to participate in the meetings of the Board, provided, that such representative shall agree to hold in confidence all information so provided; and provided further, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest, or if the Board has reasonably and in good faith determined that such Investor is a Competitor.

(d) Committees; Frequency; Expenses; Notices. Each Investor Director shall have the right to be on any committee of the Board. All meetings of the Board shall be held either telephonically or by video conferencing or in person; provided, that each director of the Board taking part in the meeting is able to hear each other director taking part in such meeting and that each director must acknowledge his or her presence for the purpose of the meeting and any director not doing so shall not be entitled to speak or vote at the meeting. Meetings of the Board shall take place at a minimum of once every quarter, or other frequency agreed unanimously by the Board. No director of the Board shall be entitled to any remuneration for serving in such

capacity as a director; provided that the Company shall reimburse the directors for all reasonable out-of-pocket expenses incurred in connection with attending any meetings of the Board and any committee thereof. The Company shall ensure that a notice of each meeting, agenda of the business to be transacted at such meeting and all documents and materials to be circulated or presented at such meeting are sent to all directors entitled to receive notice of the meeting at least seven (7) Business Days (or for any emergency meetings or otherwise as may be appropriate under the circumstances, as promptly as reasonably practicable) before such meeting and a copy of the minutes of such meeting is sent to all such directors within twenty (20) days following such meeting.

(e) Quorum; Majority Vote. At all meetings of the Board, a majority of directors (including the director appointed by WuXi (if any) and the director appointed by HOPU (if any)) shall be required to constitute a quorum for the transaction of business. If such a quorum is not present within one hour after the time appointed for a meeting for which notice has been duly given, the meeting shall adjourn to the same place and time seven (7) days later. If the required quorum is not present at the time fixed for such adjourned meeting, the directors of the Board present shall constitute the required quorum. The act of a majority of the directors of the Board present at any meeting at which there is a quorum shall be the act of the Board, subject to this Section 1.2(e) and subject to obtaining the required approvals under Section 8.4, as applicable. Meeting of the Board may be called by any director on ten (10) Business Days’ prior written notice to each director (provided that it shall be three (3) Business Days’ prior written notice to each director for any special matters if all the directors who are entitled to vote at the meeting give written consent on such notice) and the written notice shall expressly set forth the agenda of the Board meeting and the related supporting documents (if any), but a meeting of directors held without ten (10) Business Days’ notice having been given to all directors shall be valid if all the directors who are entitled to vote at the meeting waive such notice of the meeting either before or after such meeting, and for this purpose the presence of a director at a meeting shall constitute waiver by such director. In the event that any holder of Ordinary Shares and/or Preferred Shares shall have a conflict of interest (as determined in accordance with the Company’s then-current conflict of interest policy adopted by the Board) with respect to a matter to be approved by the Board hereunder (a “Shareholder Conflict”), the director(s) appointed by such holder of Ordinary Shares and/or Preferred Shares shall fully disclose the conflict of interest to the Board and shall vote with respect to such matter in a manner that is in the best interests of the Company in compliance with his or her fiduciary duties to the Company as a director of the Company.

2.3 Demand Registration.

(a) Request by Holders. If the Company shall, at any time after the earlier of (i) the third (3^rd) anniversary of the Initial Closing (as defined in the Purchase Agreement) or (ii) six (6) months following the taking effect of a registration statement for the IPO, receive a written request from the Holders of twenty percent (20%) of the Registrable Securities then outstanding that the Company file a registration statement under the Securities Act with the aggregate offering price for such registration not less than US$10,000,000 pursuant to this Section 2.3, then the Company shall, within ten (10) Business Days of the receipt of such written request, give written notice of such request (the “Request Notice”) to all Holders, and use its best efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be registered and included in such registration by written notice given by such Holders to the Company within twenty (20) days after receipt of the Request Notice, subject only to the limitations of this Section 2.3; provided that the Company shall not be obligated to effect any such registration if the Company has, within the six (6) months period preceding the date of such request, already effected a registration under the Securities Act pursuant to this Section 2.3 or Section 2.5 or in which the Holders had an opportunity to participate pursuant to the provisions of Section 2.4, other than a registration from which the Registrable Securities of the Holders have been excluded (with respect to all or any portion of the Registrable Securities the Holders requested be included in such registration) pursuant to the provisions of Section 2.4(a).

(b) Underwriting. If the Holders initiating the registration request under this Section 2.3 (the “Initiating Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part of their request made pursuant to this Section 2.3 and the Company shall include such information in the Request Notice. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Holders of a majority of the Registrable Securities being registered and reasonably acceptable to the Company. Notwithstanding any other provision of this Section 2.3, if the underwriter(s) advise(s) the Company in writing that marketing

factors require a limitation of the number of securities to be underwritten then the Company shall so advise all Holders of Registrable Securities which would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s) and allocated to the Holders of Registrable Securities on a pro rata basis according to the number of Registrable Securities then outstanding held by each such Holder requesting registration; provided, however, that the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities are first entirely excluded from the underwriting and registration including, without limitation, 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. 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), 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.

(c) Maximum Number of Demand Registrations. The Company shall not be obligated to effect more than three (3) such registrations pursuant to this Section 2.3. A registration will count for this purpose only if (i) all Registrable Securities requested to be registered are registered, and (ii) it is closed, or withdrawn at the request of the Initiating Holders (other than as a result of a material adverse change to the Company).

(d) Deferral. Notwithstanding the foregoing, if the Company shall furnish to the Holders requesting registration pursuant to this Section 2.3, a certificate signed by the president or chief executive officer of the Company stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its shareholders for such registration statement to be filed at such time, then the Company shall have the right to defer such filing for a period during which such filing would be materially detrimental but in any case no more than ninety (90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period; provided further, that the Company shall not register any other of its shares during such twelve (12) month period. A demand right shall not be deemed to have been exercised until such deferred registration shall have been effected.

2.4 Piggyback Registrations.

(a) The Company shall notify all Holders of Registrable Securities in writing at least thirty (30) days prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding registration statements relating to any registration under Section 2.3 or Section 2.5 of this Agreement or to any employee benefit plan or a corporate reorganization) and shall afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of Registrable Securities such

Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein.

(b) Underwriting. If a registration statement under which the Company gives notice under this Section 2.4 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable Securities to be included in a registration pursuant to this Section 2.4 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) or the Board determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) or the Company 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 the 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 third, 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 fifty percent (50%) 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), 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.

(c) Not Demand Registration. Registration pursuant to this Section 2.4 shall not be deemed to be a demand registration as described in Section 2.3 above. There shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 2.4.

2.5 Form F-3 Registration. In case the Company shall receive from any Holder or Holders of 10% of all Registrable Securities then outstanding a written request or requests that the Company effect a registration on Form F-3 (or Form S-3 or an equivalent registration in a jurisdiction outside of the U.S., if available for use by the Company) 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:

(a) Notice. Promptly give written notice of the proposed registration and the Holder’s or Holders’ request therefor, and any related qualification or compliance, to all other Holders of Registrable Securities; and

(b) Registration. As soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holders or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after the Company provides the notice contemplated by Section 2.5(a); provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.5:

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

(2) 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$5,000,000;

(3) 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 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 2.5; provided that the Company shall not register any of its other shares during such sixty (60) day period.

(4) if the Company has, within the one (1) year period preceding the date of such request, already effected two registrations under the Securities Act other than a registration from which the Registrable Securities of the 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 2.3(b) and 2.4(b); or

(5) 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.

(c) Not Demand Registration. Form F-3 registrations shall not be deemed to be demand registrations as described in Section 2.3 above. There shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 2.5; provided that there shall be no more than two of such registrations per year.

(d) Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.5 intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.3(b) shall apply to such registration.

2.6 Expenses. All Registration Expenses incurred in connection with any registration pursuant to Sections 2.3, 2.4 or 2.5 (but excluding Selling Expenses) and the reasonable fees and disbursements not to exceed US$50,000 of one counsel for the selling Holders selected by Holders of a majority of the Registrable Securities to be registered shall be borne by the Company. Each Holder participating in a registration pursuant to Sections 2.3, 2.4 or 2.5 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 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 2.3 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 2.3 (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 2.3.

2.7 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:

(a) Registration Statement. Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, 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.

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

(c) Prospectuses. Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the

Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration.

(d) Blue Sky. Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act.

(e) 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.

(f) 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.

(g) 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 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 (x) the effective date of the registration statement covering such Registrable Securities and (y) 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.

2.8 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 2.3, 2.4 or 2.5 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.

2.9 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.3, 2.4 or 2.5:

(a) By the Company. To the extent permitted by law, the Company will

indemnify and hold harmless each Holder, its partners, officers, directors, legal counsel, investment advisers, 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 U.S. 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”):

(i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto;

(ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or

(iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any U.S. federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any U.S. 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, investment adviser, 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 Subsection 2.9(a) 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, legal counsel, investment adviser, underwriter or controlling person of such Holder.

(b) By Selling Holders. To the extent permitted by law, each selling Holder will, severally and not jointly, 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 U.S. 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 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 2.9(b) 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 2.9(b) exceed the net proceeds received by such Holder in the registered offering out of which the applicable Violation arises.

(c) Notice. Promptly after receipt by an indemnified party under this Section 2.9 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 2.9, 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 reasonable 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 2.9 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 2.9.

(d) 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 2.9 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 2.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any indemnified party in circumstances for which indemnification is provided under this Section 2.9; 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, when combined with the amounts paid or payable by such Holder pursuant to Section 2.9(b), 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.

(e) Survival. The obligations of the Company and Holders under this Section 2.9 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.

2.10 Termination of the Company’s Obligations. The Company’s obligations under Sections 2.3, 2.4 and 2.5 with respect to any Registrable Securities proposed to be sold by a Holder in a registration pursuant to Section 2.3, 2.4 or 2.5 shall terminate upon the earliest to occur of:

(a) the closing of a Deemed Liquidation Event, as such term is defined in the Restated Articles;

(b) such time after consummation of the IPO as SEC Rule 144 or another similar exemption under the Securities Act is available for the sale of all of such Holder’s shares without limitation, during a three (3)-month period without registration;

2.11 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 Section 2, 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.

2.12 Rule 144 Reporting. With a view to make 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:

(a) Make and keep adequate current 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;

(b) 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

(c) 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.

2.13 Market Stand-Off. Each Holder agrees that, so long as it holds any voting securities of the Company, upon request by the underwriters managing the IPO of the Company’s securities, it will not sell or otherwise transfer or dispose of any securities 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 such underwriters, 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 IPO or the pricing date of such offering as may be requested by the underwriters, provided that all directors and officers that holds any shares in the Company and all shareholders holding at least one percent (1%) of the issued and outstanding Ordinary Shares (on an as-converted but non-diluted basis) agree to be bounded by the same lock-up requirements. The Holder agree to execute and deliver to the underwriters a lock-up agreement containing substantially similar terms and conditions as those contained herein. Notwithstanding the foregoing, the lock-up requirements above shall not apply to shares of the Company purchased in the IPO or on the open market thereafter and there shall be a pro-rata release for all Holders of the Registrable Securities in the event that the underwriters elect to early release anyone else subject to lock-up requirements.

3. RIGHT OF PARTICIPATION.

3.1 General. The Major Investors and/or their Affiliates shall have the right of first refusal to purchase (or designate any other person to purchase) their respective Pro Rata Share (as defined below) of any New Equity Securities (as defined in the Restated Articles) that the Company may from time to time issue after the date of this Agreement (the “Major Investor Right of Participation”).

3.2 Pro Rata Share. For the purposes of the Major Investor Right of Participation, a Major Investor’s “Pro Rata Share” is the ratio of (a) the number of Ordinary Shares (calculated on an as-converted basis) held by such Major Investor and its Affiliates, to (b) the total number of Ordinary Shares (calculated on an as-converted and fully-diluted basis, but excluding any reserved but ungranted options under the Company’s equity incentive plans) held by all shareholders immediately prior to the issuance of New Equity Securities giving rise to the Major Investor Right of Participation.

3.3 Procedures.

(a) First Participation Notice. In the event that the Company proposes to undertake an issuance of New Equity Securities (in a single transaction or a series of related transactions), it shall give to each Major Investor written notice of its intention to issue New Equity Securities (the “First Participation Notice”), describing the amount and type of New Equity Securities, the price and the general terms upon which the Company proposes to issue such New Equity Securities. Each Major Investor shall have twenty (20) Business Days from the date of receipt of any such First Participation Notice (the “First Participation Period”) to agree in writing to purchase such Major Investor’s Pro Rata Share of the New Equity Securities for the price and upon the terms and conditions specified in the First Participation Notice by giving written notice to the Company and stating therein the number of New Equity Securities to be purchased (not to exceed such Major Investor’s Pro Rata Share of the New Equity Securities). If any Major Investor fails to so agree in writing within the First Participation Period to purchase such Major Investor’s full Pro Rata Share of an offering of the New Equity Securities, then such Major Investor shall forfeit the right hereunder to purchase that part of its Pro Rata Share of the New Equity Securities that it did not agree to purchase.

(b) Second Participation Notice; Oversubscription. If any Major Investor fails or declines to exercise its Major Investor Right of Participation in accordance with Subsection (a) above, the Company shall promptly give notice (the “Second Participation Notice”) to other Major Investors who exercised their Major Investor Right of Participation (the “Right Participants”) in accordance with Subsection (a) above. Each Right Participant shall have seven (7) Business Days from the date of the Second Participation Notice (the “Second Participation Period”) to notify the Company of its desire to purchase more than its Pro Rata Share of the New Equity Securities, stating the number of the additional New Equity Securities it proposes to purchase (the “Additional Number”). If, as a result thereof, such oversubscription exceeds the total number of the remaining New Equity Securities available for purchase, each oversubscribing Right Participant will be cut back by the Company with respect to its oversubscription to that number of remaining New Equity Securities equal to the lesser of (x) the Additional Number and (y) the product obtained by multiplying (i) the number of the remaining New Equity Securities available for subscription by (ii) a fraction, the numerator of which is the number of Ordinary Shares (calculated on an as-converted basis) held by such oversubscribing Right Participant (and its Affiliates) and the denominator of which is the total number of Ordinary Shares (calculated on an as-converted basis) held by all the oversubscribing Right Participants (and their Affiliates). Each Right Participant shall be obligated to buy such number of New Equity Securities as determined by the Company pursuant to this Section 3.3 and the Company shall so notify the Right Participants within fifteen (15) Business Days following the date of the Second Participation Notice.

3.4 Failure to Exercise. Upon the expiration of the Second Participation Period, or in the event no Major Investor exercises the Major Investor Right of Participation within the First Participation Period, the Company shall have one hundred and twenty (120) days thereafter to sell the New Equity Securities described in the First Participation Notice (with respect to which the Major Investor Right of Participation hereunder was not exercised) at the same or higher price and upon non-price terms not more favorable to the purchasers thereof than specified in the First Participation Notice. In the event that the Company has not issued and sold such New Equity

Securities within such one hundred and twenty (120) days period, then the Company shall not thereafter issue or sell any New Equity Securities without again first offering such New Equity Securities to the Major Investors pursuant to this Section 3.

3.5 Termination. The Major Investor Right of Participation shall terminate (i) immediately before the consummation of the IPO; or (ii) upon the closing of a Deemed Liquidation Event, as such term is defined in the Restated Articles.

4. TRANSFER RESTRICTIONS.

4.1 Certain Definitions. For purposes of this Section 4, “Restricted Shares” means any of the Company’s outstanding Ordinary Shares (other than Ordinary Shares converted from Preferred Shares) held by any Key Holder. A “ROFR and Co-Sale Right Holder” means a Major Investor, its Affiliates, and its respective permitted assignees to whom its rights under this Section 4 have been duly assigned in accordance with Section 9.6(b) of this Agreement, or any other person designated by such Major Investor.

4.2 Sale of Restricted Shares; Notice of Sale. Subject to Section 4.7 of this Agreement, if any holder of Restricted Shares (the “Selling Shareholder”) proposes to sell or transfer any Restricted Shares held by it to a Third Party, then the Selling Shareholder shall promptly give written notice (the “Transfer Notice”) to each ROFR and Co-Sale Right Holder and the Company prior to such Transfer. The Transfer Notice shall describe in reasonable detail the proposed sale or transfer, including without limitation, the number of Restricted Shares to be Transferred (the “Offered Shares”), the consideration to be paid, the nature and other material terms of such Transfer, and the name and address of each prospective transferee.

4.3 Right of First Refusal.

(a) Company’s Option. The Company shall have an option for a period of fifteen (15) Business Days from receipt of the Transfer Notice (the “Company Election Period”) to elect to purchase the Offered Shares at the same price and subject to the same material terms and conditions as are described in the Transfer Notice. The Company may exercise such purchase option and, thereby, purchase all or a portion of the Offered Shares by notifying the Selling Shareholder in writing (the “Company Election Notice”) before expiration of the fifteen (15) Business Day period as to the number of such Offered Shares which it wishes to purchase.

(b) Additional Transfer Notice. If the Company has declined to purchase all, or a portion of, the Offered Shares pursuant to the immediately preceding paragraph, then the Selling Shareholder shall, within three (3) Business Days after the expiration of the Company Election Period, give each ROFR and Co-Sale Right Holder an “Additional Transfer Notice” which shall include all of the information and certifications required in a Transfer Notice and shall additionally identify the Offered Shares which the Company has declined to purchase (the “Remaining Shares”) and briefly describe the ROFR and Co-Sale Right Holder’s rights of first refusal and co-sale rights with respect to the Remaining Shares.

(c) ROFR and Co-Sale Right Holders’ Option. Each ROFR and Co-Sale Right Holder shall have the right, exercisable upon written notice to the Selling Shareholder, the Company, and each other ROFR and Co-Sale Right Holder, within fifteen (15) Business Days

following the date of the Additional Transfer Notice (the “Holder Election Period”), to elect to purchase all or any part of its pro rata share of the Remaining Shares equivalent to the product obtained by multiplying the aggregate number of the Remaining Shares by a fraction, the numerator of which is the number of Ordinary Shares (calculated on an as-converted basis) held by such ROFR and Co-Sale Right Holder and its Affiliates at the time of the transaction and the denominator of which is the total number of Ordinary Shares (calculated on an as-converted basis) owned by all the ROFR and Co-Sale Right Holders and their Affiliates at the time of the transaction (the “First Refusal Allotment”), at the same price and subject to the same material terms and conditions as described in the Additional Transfer Notice. To the extent that any ROFR and Co-Sale Right Holder does not exercise its right of first refusal to the full extent of its First Refusal Allotment, the Selling Shareholder and the exercising ROFR and Co-Sale Right Holders shall, within five (5) Business Days after the end of the First Refusal Period, make such adjustments to the First Refusal Allotment of each exercising ROFR and Co-Sale Right Holder so that any remaining Offered Shares may be allocated to those ROFR and Co-Sale Right Holders fully exercising their rights of first refusal on a pro rata basis. For purpose of the foregoing sentence, “on a pro rata basis” means on the basis of the ratio of (a) the number of Ordinary Shares (calculated on an as-converted basis) held by a ROFR and Co-Sale Right Holder exercising its right of first refusal and its Affiliates, to (b) the total number of Ordinary Shares (calculated on an as-converted basis) then held by all ROFR and Co-Sale Right Holders fully exercising their respective rights of first refusal and their Affiliates.

(d) Action Required. A ROFR and Co-Sale Right Holder shall not have the right to purchase any of the Remaining Shares unless it exercises its right of first refusal within the Holder Election Period to purchase up to all, or any of its pro rata share, of the Remaining Shares.

(e) Expiration Notice. Within ten (10) Business Days after expiration of the Holder Election Period, the Company will give written notice (the “First Refusal Expiration Notice”) to the Selling Shareholder and each ROFR and Co-Sale Right Holder specifying either (i) that all of the Offered Shares were purchased by the Company and/or ROFR and Co-Sale Right Holders by exercising their rights of first refusal, or (ii) that the Company and the ROFR and Co-Sale Right Holders have not purchased all of the Offered Shares, in which case the First Refusal Expiration Notice will specify the Co-Sale Pro Rata Portion (as defined below) of the remaining Offered Shares for the purpose of their co-sale rights described in Section 4.4 below.

(f) Purchase Price. The purchase price per share for the Offered Shares to be purchased by the Company and/or ROFR and Co-Sale Right Holders exercising their right of first refusal will be the price per share set forth in the Transfer Notice or the Additional Transfer Notice (as appropriate), and will be payable as set forth in Section 4.3(g). If the purchase price in the Transfer Notice/Additional Transfer Notice includes consideration other than cash, the cash equivalent value of the non-cash consideration will be determined by the Board in good faith, which determination will be binding upon the Company, the ROFR and Co-Sale Right Holders, and the Selling Shareholder, absent fraud or error.

(g) Payment. Payment of the purchase price for the Offered Shares purchased by the Company and/or the ROFR and Co-Sale Right Holders shall be made within thirty (30) Business Days following the date of the First Refusal Expiration Notice, unless the

Transfer Notice/Additional Transfer Notice contemplates a later date or unless the value of the purchase price has not yet been established pursuant to Section 4.3(f). Payment of the purchase price shall be made by wire transfer or check as directed by the Selling Shareholder.

(h) Rights of a Selling Shareholder. If the Company or any ROFR and Co-Sale Right Holder exercises its right of first refusal to purchase the Offered Shares, then, upon the date the notice of such exercise is given by such ROFR and Co-Sale Right Holder, the Selling Shareholder will have no further rights as a holder of such Offered Shares except the right to receive payment for such Offered Shares from the Company/such ROFR and Co-Sale Right Holder in accordance with the terms of this Agreement, and the Selling Shareholder will forthwith cause all certificate(s) evidencing such Offered Shares to be surrendered to the Company for the transfer.

(i) Application of Co-Sale Rights. If the Company and the ROFR and Co-Sale Right Holders have not elected to purchase all of the Offered Shares, then the sale of the remaining Offered Shares will become subject to the co-sale rights set forth in Section 4.4 below.

4.4 Co-Sale Right. To the extent the Company and the ROFR and Co-Sale Right Holders have not exercised their right of first refusal with respect to all the Offered Shares, then each ROFR and Co-Sale Right Holder that has not exercised its right of first refusal provided in Section 4.3 above shall have the right, exercisable upon written notice to the Selling Shareholder, the Company and each other ROFR and Co-Sale Right Holder (the “Co-Sale Notice”) within fifteen (15) Business Days after receipt of the First Refusal Expiration Notice (the “Co-Sale Right Period”), to participate in such sale of the Offered Shares at the same price and subject to the same terms and conditions as set forth in the Additional Transfer Notice. The Co-Sale Notice shall set forth the number of Company securities (on as-converted to Ordinary Shares basis) that such participating ROFR and Co-Sale Right Holder wishes to include in such Transfer, which amount shall not exceed the Co-Sale Pro Rata Portion (as defined below) of such ROFR and Co-Sale Right Holder. To the extent one or more of the ROFR and Co-Sale Right Holders exercise such right of participation in accordance with the terms and conditions set forth below, the number of Offered Shares that the Selling Shareholder may sell in the transaction shall be correspondingly reduced. The co-sale right of each ROFR and Co-Sale Right Holder shall be subject to the following terms and conditions:

(a) Co-Sale Pro Rata Portion. Each ROFR and Co-Sale Right Holder exercising its co-sale right may sell all or any part of that number of Ordinary Shares held by it and its Affiliates (on an as-converted basis) that is equal to the product obtained by multiplying (x) the aggregate number of the Offered Shares subject to the co-sale right hereunder by (y) a fraction, the numerator of which is the number of Ordinary Shares (calculated on an as-converted basis) owned by such ROFR and Co-Sale Right Holder exercising its co-sale rights at the time of the Transfer and its Affiliates and the denominator of which is the number of all Ordinary Shares (calculated on an as-converted basis) owned by the Selling Shareholder (excluding any Ordinary Shares of the Selling Shareholder on which any ROFR and Co-Sale Right Holder has exercised its right of first refusal) and all ROFR and Co-Sale Right Holders exercising their co-sale rights hereunder and their Affiliates (“Co-Sale Pro Rata Portion”).

(b) Transferred Shares. Each participating ROFR and Co-Sale Right Holder shall effect its participation in the Transfer by promptly delivering to the Selling

Shareholder for Transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent:

(i) the number of Company securities which such ROFR and Co-Sale Right Holder elects to sell;

(ii) that number of Preferred Shares, which is at such time convertible into the number of Ordinary Shares that such ROFR and Co-Sale Right Holder elects to sell (calculated on an as-converted basis); provided in such case that, if the prospective purchaser objects to the Transfer of Preferred Shares in lieu of Ordinary Shares, such ROFR and Co-Sale Right Holder shall convert such Preferred Shares into Ordinary Shares and deliver certificates for Ordinary Shares as provided in Subsection 4.4(b)(i) above. The Company agrees to make any such conversion concurrent with the actual Transfer of such shares to the purchaser; or

(iii) a combination of the above.

(c) Payment to ROFR and Co-Sale Right Holders; Registration of Transfer. The share certificate or certificates that the participating ROFR and Co-Sale Right Holder delivers to the Selling Shareholder pursuant to Section 4.4(b) shall be Transferred to the prospective purchaser in consummation of the sale of the Offered Shares pursuant to the terms and conditions specified in the Additional Transfer Notice, and the Selling Shareholder shall concurrently therewith remit to such ROFR and Co-Sale Right Holder that portion of the sale proceeds to which such ROFR and Co-Sale Right Holder is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities from a ROFR and Co-Sale Right Holder exercising its co-sale right hereunder, the Selling Shareholder shall not sell to such prospective purchaser or purchasers any Offered Shares unless and until, simultaneously with such Transfer, the Selling Shareholder shall purchase such shares or other securities from such ROFR and Co-Sale Right Holder. The Company shall, upon surrendering by the prospective purchaser or the Selling Shareholder of the certificates, if any, for the Preferred Shares or Ordinary Shares being Transferred from the participating ROFR and Co-Sale Right Holders as provided above, make proper entries in the register of members of the Company and cancel the surrendered certificates and issue any new certificates in the name of the prospective purchaser or the Selling Shareholder, as the case may be, as necessary to consummate the transactions in connection with the exercise by ROFR and Co-Sale Right Holders of their co-sale rights under this Section 4.4.

4.5 Right to Transfer. The Selling Shareholder may, not later than ninety (90) days following delivery to the Company of the Transfer Notice, conclude a Transfer of the Offered Shares covered by the Transfer Notice and the number of which shall have not been reduced pursuant to the right of first refusal and co-sale right of the Company and the ROFR and Co-Sale Right Holders hereunder, which in each case shall be on the same terms and conditions as those described in the Transfer Notice and Additional Transfer Notice. Any proposed transfer on terms and conditions which are, in the opinion of the ROFR and Co-Sale Right Holders, materially different from those described in the Transfer Notice and Additional Transfer Notice, as well as any subsequent proposed transfer of any Restricted Shares by the Selling Shareholder, shall again be subject to the right of first refusal and co-sale right of the Company and the ROFR and Co-Sale

Right Holders and shall require compliance by the Selling Shareholder with the procedures described in Section 4 of this Agreement.

4.6 Exempt Transfers. Subject to Section 4.7 hereof, the restrictions and provisions set forth in Sections 4.3 and 4.4 shall not apply to (a) any Transfer of the Restricted Shares to the Company pursuant to a repurchase right or right of first refusal held by the Company in the event of a termination of employment or consulting relationship, (b) with respect to a Selling Shareholder who is an individual, any Transfer of the Restricted Shares to the parents, children or spouse, or to trusts for the benefit of such persons, of such Selling Shareholders for bona fide estate planning purposes, (c) with respect to a Selling Shareholder who is an entity, any Transfer of the Restricted Shares to its wholly owned Affiliates, or (d) any transfer by a key holder listed in Schedule IV attached hereto (each a “Key Holder”) to any person of up to one percent (1%) of the total shares then held by such Key Holder as of the Initial Closing on a cumulative basis (collectively the “Permitted Transferees”, and each, a “Permitted Transferee”, of such Selling Shareholder); provided that adequate documentation therefor is provided to the Company and the ROFR and Co-Sale Right Holders and that any such Permitted Transferee executes and delivers to the Company and the other Parties an adoption agreement in substantially the form attached hereto as Exhibit A and in the capacities of the relevant Selling Shareholder for all purposes hereunder; and provided further, that such Selling Shareholder shall remain liable for any breach by such its Permitted Transferee of any provision hereunder. For the avoidance of doubt, Transfer restrictions under this Section 4 do not apply to Transfer of the Preferred Shares or Ordinary Shares converted therefrom.

4.7 Prohibited Transfers. Notwithstanding anything to the contrary herein, except for Transfers to Permitted Transferees as provided in Section 4.6 above, none of the Key Holders shall Transfer, through one or a series of transactions any Restricted Shares to any person prior to the QIPO (as defined below), unless with the prior written consents of the Required Holders (as defined below); provided, that the Transfers by a Key Holder to any Third Party of up to one percent (1%) of the total Shares held by such Key Holder as of the Initial Closing on a cumulative basis shall not be subject to the foregoing restrictions in this Section 4.7. For the purposes of this Agreement, the term “QIPO” means a firm commitment underwritten public offering of the Ordinary Shares of the Company (or depositary receipts representing such Ordinary Shares) on the NASDAQ Stock Market or another internationally recognized securities exchange as approved by the Board at an offering price per share to the public of at least 1.25 times the Series B Issue Price (as defined in the Restated Articles) and with gross proceeds to the Company of not less than US$50,000,000.
