Such Purchaser understands that the Shares are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such Shares may be resold without registration under the Securities Act only in certain limited circumstances. Accordingly, such Purchaser represents that it is familiar with Rule 144 of the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

5.13 Beneficial Ownership. Except as indicated in any signature page for a Purchaser, (i) the purchase by such Purchaser of the Shares issuable to it at the Closing will not result in the Purchaser (individually or together with any other Person with whom the Purchaser has identified, or will have identified, itself as part of a “group” in a public filing made with the Commission involving the Company’s securities, where such aggregation would be made according to Section 13(d) of the Exchange Act) acquiring, or obtaining the right to acquire, in excess of 19.999% of the outstanding Ordinary Shares or the voting power of the Company on a post-transaction basis that assumes that such Closing shall have occurred and (ii) the Purchaser does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired, or obtained the right to acquire, as a result of such Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.999% of the outstanding Ordinary Shares or the voting power of the Company on a post-transaction basis that assumes that each Closing shall have occurred (including assuming the effectiveness of any “blocker” or similar limitations on beneficial ownership contained in the applicable documentation for the Shares).

5.14 CSRC Filings Assistance. The Purchaser understands that the Company is required to make a filing with the CSRC in respect of the transaction under this Agreement within three (3) PRC working days following the Closing Date. The Purchaser agrees to provide the Company with the information or assistance reasonably necessary to complete the above CSRC Filings as set forth on Schedule D, and as otherwise requested by the Company, including the completion prior to the Closing Date of any questionnaires provided to such Purchaser by the Company related to information needed by the Company in order to complete its CSRC Filings, and shall provide corresponding materials in response to any subsequent inquiries from the CSRC, if applicable.

SECTION 6. REGISTRATION OF THE SHARES AND COMPLIANCE WITH THE SECURITIES ACT.

6.1 Registration Procedures and Expenses.

(a) Secondary Registration Statement. The Company shall prepare and file, on or before the date that is forty-five (45) days after the Closing (the “Filing Deadline”), with the Commission a Registration Statement on Form F-3 (except if the Company is not then eligible to register for resale the Shares (together with any shares of capital stock issued or issuable, from time to time, upon any reclassification, share combination, share subdivision, stock split, share dividend or similar transaction or event or otherwise as a distribution on, in exchange for or with respect to any of the foregoing, in each case held at the relevant time by a Purchaser the “Registrable Securities”), on Form F-3, in which case such registration shall be on Form F-1), as appropriate (the “Secondary Registration Statement”), relating to and providing for the resale of the Shares by the Purchasers on a continuous basis pursuant to Rule 415 under the Securities Act or, if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Purchasers may reasonably specify. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the Registrable Securities on the Secondary Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities (and notwithstanding that the Company used diligent efforts to advocate with the staff of the Commission for the registration of all or a greater portion of the Registrable Securities), the Secondary Registration Statement shall register for resale such number of Registrable Securities that is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of Registrable Securities for which resale is to be registered for each selling shareholder named in the Secondary Registration Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable after being permitted to register additional Registrable Securities under Rule 415 under the Securities Act, the Company shall amend the Secondary Registration Statement or file one or more new registration statement(s) (such amendment or new registration statement, a “Remainder Registration Statement”) to register such additional Registrable Securities not included in the Secondary Registration Statement and cause such Remainder Registration Statement to become effective as promptly as practicable after the filing thereof, but in any event no later than thirty (30) calendar days after the filing of such Remainder Registration Statement (the “Remainder Effectiveness Deadline”); provided, that the Remainder Effectiveness Deadline shall be extended to sixty (60) calendar days after the filing of such Remainder Registration Statement if the SEC notifies the Company that it will “review” such Remainder Registration Statement; provided, further, notwithstanding the foregoing, that the Company shall use reasonable best efforts to have such Remainder Registration Statement declared effective within five (5) Business Days after the date the Company is notified orally or in writing (whichever is earlier) by the Commission that such Remainder Registration Statement will not be reviewed or will not be subject to further review. Any failure by the Company to file the Secondary Registration Statement by the Filing Deadline or to effect the Secondary Registration Statement by the Effectiveness Deadline or the Remainder Registration Statement by the Remainder Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or effect the Secondary Registration Statement or Remainder Registration Statement set forth in this Section 6.1(a).

(b) The Company shall use its reasonable best efforts, subject to receipt of necessary information from the Purchasers, to cause the Commission, to declare a Secondary Registration Statement covering the Shares effective as soon as practicable after the date of the filing thereof and in any event no later than the earlier of (i) sixty (60) days after such filing if the Secondary Registration Statement has been filed on Form F-3, and no later than ninety (90) days after such filing if such Secondary Registration Statement has been filed on Form F-1, and in either case, no later than forty-five (45) days after such filing in the event the Secondary Registration Statement is not reviewed by the Commission and (ii) the fifth (5th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Secondary Registration Statement will not be reviewed or will not be subject to further review (in either case, such date, the “Effectiveness Deadline”).

(c) The Company shall promptly prepare and file with the Commission such amendments and supplements to the Secondary Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Secondary Registration Statement effective until the earliest of (i) such time as all of the Shares purchased by the Purchasers pursuant to the terms of this Agreement have been sold pursuant to the Secondary Registration Statement, or (ii) such time as the Shares become eligible for resale by non-Affiliates without any volume limitations or other restrictions pursuant to Rule 144(b)(1)(i) or any other rule of similar effect.

(d) Notwithstanding the foregoing obligations, the Company may, upon written notice to the Purchasers, for a reasonable period of time, not to exceed forty-five (45) days in the case of clauses (A) and (B) below, or thirty (30) days in the case of clause (C) below (each, a “Blackout Period”), delay the filing of a Secondary Registration Statement or a request for acceleration of the effective date, or suspend the effectiveness of any Secondary Registration Statement, in the event (A) of a pending significant corporate development with respect to the Company that, upon advice of legal counsel, the Company’s Board of Directors determines in good faith to be material and would require additional disclosure by the Company in the Secondary Registration Statement of such information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company’s Board of Directors, upon advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, (B) the Company does not yet have appropriate financial statements of any acquired or to be acquired entities necessary for filing, either because such financial statements are not yet available or despite the Company using reasonable best efforts to procure such financial statements, or (C) any other event occurs that makes any statement of a material fact made in such Secondary Registration Statement, including any document incorporated by reference therein, untrue or that requires the making of any additions or changes in the Registration Statement in order to make the statements therein not misleading; provided, however, that in the case of a Blackout Period pursuant to clause (A) above, the Blackout Period shall terminate upon the earlier of (i) such forty-five (45) day period or (ii) the completion, resolution or public announcement of the relevant transaction or event. If the Company suspends the effectiveness of a Secondary Registration Statement pursuant to this Section 6.1(d), the Company shall, as promptly as reasonably practicable following the termination of the circumstance which entitled the Company to do so, take such actions as may be necessary to reinstate the effectiveness of such Secondary Registration Statement and give written notice to the Purchasers authorizing the Purchasers to resume offerings and sales pursuant to such Registration Statement. If as a result thereof the prospectus included in such Secondary Registration Statement has been amended or supplemented to comply with the requirements of the Securities Act, the Company shall enclose such revised prospectus with the notice to each Purchaser given pursuant to this Section 6. After the expiration of any Blackout Period and without further request from any Purchaser, the Company shall effect the filing of amendments or supplements to the Secondary Registration Statement, or the filing of other documents, as necessary to allow the Purchasers to resell the Registrable Securities as set forth herein. In providing to a Purchaser the written notice of a Blackout Period as contemplated by the first sentence of this Section 6.1(d), the Company shall not (without the prior written consent of such Purchaser) disclose to such Purchaser any material nonpublic information giving rise to or otherwise associated with such Blackout Period.

(e) Upon notification by the Commission that the Secondary Registration Statement will not be reviewed or is not subject to further review by the Commission, the Company shall within three Business Days following the date of such notification request acceleration of such Secondary Registration Statement (with the requested effectiveness date to be not more than two Business Days later).

(f) The Company shall furnish to the Purchasers with respect to the Shares registered under any Secondary Registration Statement (and to each underwriter, if any, of such Shares) such number of copies of prospectuses and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares by the Purchaser.

(g) The Company shall bear all expenses in connection with the procedures in paragraphs (a) through (f) of this Section 6.1 and the registration of the Shares pursuant to the Secondary Registration Statement, other than fees and expenses, if any, of counsel or other advisers to the Purchasers or underwriting discounts, brokerage fees and commissions incurred by the Purchaser, if any in connection with the offering of the Shares pursuant to the Secondary Registration Statement.

(h) In order to enable the Purchasers to sell the Shares under Rule 144 (or its successor rule) and any other rule or regulation of the Commission that may at any time permit the Purchasers to sell Ordinary Shares to the public without registration, the Company shall use its reasonable best efforts to comply with the requirements of Rule 144, including without limitation, (i) make and keep adequate current public information available, as those terms are understood and defined in Rule 144 and (ii) timely file all reports and other documents required to be filed by the Company under the Exchange Act.

(i) The Company shall provide the Purchasers a reasonable opportunity to review and comment on all disclosures regarding the Purchasers and any plan of distribution proposed by them in connection with the preparation of any Secondary Registration Statement not less than five (5) Business Days prior to the filing of such Secondary Registration Statement. Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name any Purchaser or Affiliate of a Purchaser as an “underwriter” without the prior written consent of such Purchaser; provided, that if the Commission requires that a Purchaser be identified as a statutory underwriter in either the Secondary Registration Statement or a Remainder Registration Statement, such Purchaser will have the option, in its sole and absolute discretion, to either (a) have the opportunity to withdraw from the Secondary Registration Statement or Remainder Registration Statement, as the case may be, upon its prompt written request to the Company or (b) be included as such in the Secondary Registration Statement or Remainder Registration Statement, as the case may be.

6.2 Restrictions on Transfer. Each Purchaser agrees that it will not effect any disposition of the Shares that would constitute a sale within the meaning of the Securities Act or pursuant to any applicable state securities laws, unless and until (a) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement or (b) such disposition is otherwise permitted by law, including pursuant to the procedures set forth in Rule 144 or any other applicable exemption from the registration requirements under the Securities Act. Notwithstanding the preceding sentence, no restriction shall apply to a transfer by a Purchaser that is (y) a partnership transferring to its partners or former partners in accordance with partnership interests, or (z) a limited liability company transferring to its members or former members in accordance with member interests.

6.3 Indemnification. For the purpose of this Section 6.3: (i) the term “Purchaser/Affiliate” shall mean any officer, director, agent, partner, member, manager, stockholder, affiliate or employees of the Purchaser and any investment adviser of a Purchaser, or any transferee who is an affiliate of a Purchaser, and any person who controls a Purchaser or any affiliate of a Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (and the officers, directors, partners, members, managers, stockholders, agents, investment advisers and employees of each such controlling person); and (ii) the term “Registration Statement” shall include any preliminary prospectus, final prospectus (the

“Prospectus”), free writing prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Secondary Registration Statement and any Remainder Registration Statement filed pursuant to this Agreement.

(a) The Company agrees to indemnify and hold harmless each Purchaser and each Purchaser/Affiliate, against any losses, claims, damages, liabilities or expenses, joint or several, that such Purchaser or Purchaser/Affiliate incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, such consent not to be unreasonably withheld or delayed), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including the Prospectus, financial statements and schedules, and all other documents filed as a part thereof or incorporated by reference therein, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A under the Securities Act, or pursuant to Rules 430B, 430C or 434 under the Securities Act, or the Prospectus, in the form first filed with the Commission pursuant to Rule 424(b) under the Securities Act, or filed as part of the Registration Statement at the time of effectiveness if no Rule 424(b) filing is required or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in light of the circumstances under which they were made, (ii) any violation or alleged violation by the Company or its agents of the Securities Act, the Exchange Act, or any other federal or state securities law or any rule or regulation thereunder, in connection with the performance or non-performance of its obligations under this Agreement or any action or inaction required of the Company in connection with any registration or (iii) arise out of or are based in whole or in part on any inaccuracy in the representations or warranties of the Company contained in this Agreement, breach of any covenant of the Company contained in this Agreement or any failure of the Company to perform its other obligations hereunder or under law, and will promptly reimburse each Purchaser and each Purchaser/Affiliate for any legal and other out-of-pocket expenses as such expenses are reasonably incurred and documented by such Purchaser or such Purchaser/Affiliate in connection with investigating, defending or preparing to defend, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Company, which consent shall not be unreasonably withheld or delayed, and the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, or (ii) the inaccuracy of any representation or warranty made by such Purchaser herein or (iii) any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by the Purchaser.

(b) Each Purchaser will severally, but not jointly, indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities or expenses that the Company, each of its directors, each of its officers who signed the Registration Statement or controlling

person reasonably incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, but only if such settlement is effected with the written consent of such Purchaser, such consent not to be unreasonably withheld or delayed) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in the light of the circumstances under which they were made, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Purchaser expressly for use therein; and will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that (i) each Purchaser’s aggregate liability under this Section 6.3 shall not exceed the amount of net proceeds received by such Purchaser on the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such indemnification obligation, and (ii) a Purchaser will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of such Purchaser, and (iii) a Purchaser will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon the gross negligence, fraud or willful misconduct of the Company, any of Company’s directors, any of Company’s officers who signed the Registration Statement or any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act.

(c) Promptly after receipt by an indemnified party under this Section 6.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 6.3 promptly notify the indemnifying party in writing thereof, but the omission to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 6.3 to the extent it is not prejudiced as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party, and the indemnifying party and the indemnified party shall have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there may be a conflict of interest between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6.3 for any legal or other expenses subsequently incurred by such indemnified party in connection

with the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, reasonably satisfactory to such indemnifying party, representing all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. In no event shall any indemnifying party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have approved in writing the terms of such settlement; provided that such approval shall not be unreasonably withheld or delayed. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of or consent to the entry of any judgment in any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by such indemnified party, unless such settlement or judgment (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding, (y) imposes no liability or obligation on the indemnified person and (z) does not include any admission of fault, culpability, wrongdoing or malfeasance by or on behalf of the indemnified person. The indemnifying party shall notify the indemnified party promptly of the institution, threat or assertion of any proceeding in connection with, arising out of, as a result of, relating to or based upon the transactions contemplated by this Agreement of which the indemnifying party is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of any of the Shares by any of the Purchasers as permitted by this Agreement. Subject to the terms of this Agreement, all reasonable and documented fees and expenses of the indemnified party (including reasonable and documented fees and expenses to the extent incurred in connection with investigating or preparing to defend such proceeding in a manner not inconsistent with this Section 6.3) shall be paid to such indemnified party, as incurred, within ten (10) Business Days of written notice thereof to the indemnifying party, provided that the indemnified party shall promptly reimburse the indemnifying party for that portion of such fees and expenses applicable to such actions for which such indemnified party is finally judicially determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) not to be entitled to indemnification hereunder.

(d) If the indemnification provided for in this Section 6.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 6.3 in respect to any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to herein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the private placement of Shares hereunder or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement and/or the Registration Statement that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount paid by such Purchaser to the Company pursuant to this Agreement for the Shares purchased by such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount such Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount received by such Purchaser from such sale. The

relative fault of the Company on the one hand and each Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by such Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in paragraph (c) of this Section 6.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in paragraph (c) of this Section 6.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this paragraph (d); provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under paragraph (c) for purposes of indemnification. The Company and the Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 6.3(d) were determined solely by pro rata allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph. Notwithstanding the provisions of this Section 6.3(d), (i) no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) each Purchaser’s aggregate liability under this Section 6.3 shall not exceed the amount of net proceeds received by such Purchaser on the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such indemnification or contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchasers’ obligations to contribute pursuant to this Section 6.3(d) are several and not joint.

6.4 Information Available. The Company, upon the reasonable request of a Purchaser, shall make available for inspection by such Purchaser, any deemed underwriter participating in any disposition pursuant to the Secondary Registration Statement and any attorney, accountant or other agent retained by the Purchasers or any deemed underwriter, all financial and other records, pertinent corporate documents and properties of the Company.

6.5 Delay in Filing or Effectiveness of Secondary Registration Statement. If a Secondary Registration Statement covering the Shares is not filed on or prior to the Filing Deadline or is not declared effective by the Commission on or prior to the Effectiveness Deadline, then for each day following the Filing Deadline or Effectiveness Deadline, as applicable, until but excluding the date the Company files or the Commission declares the Secondary Registration Statement effective, as the case may be, the Company shall, for each such day, pay each Purchaser with respect to any such failure, as liquidated damages and not as a penalty, an amount per thirty (30)-day period equal to 1.0% of the Purchase Price paid by such Purchaser for its Shares pursuant to this Agreement (calculated on a daily pro rata basis for any portion of such thirty (30)-day period prior to the cure of such failure), provided that no liquidated damages shall be payable if and to the extent to, despite best efforts by the Company to avoid a breach hereof, the Company’s failure was caused by (i) restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 or (ii) a government shutdown resulting in the SEC’s inability to review or declare effective the Registration Statement; and for any such thirty (30)-day period (or earlier period if such failure is cured prior to thirty (30) days), such payment shall be made no later than three (3) Business Days following such thirty (30)-day period (or earlier period if such failure is cured prior to thirty (30) days). Notwithstanding the foregoing provisions, in no event shall the Company be obligated to pay

any liquidated damages pursuant to this Section 6.5 to more than one Purchaser in respect of the same Shares for the same period of time or in an aggregate amount that exceeds 5.0% of the Purchase Price paid by the Purchasers for the Shares pursuant to this Agreement. Such payments shall be made to the Purchasers in immediately available funds.

SECTION 7. NO BROKER’S FEE.

Each of the Company and the Purchasers (on a several but not joint basis) hereby represents that no broker, investment banker, financial advisor or other individual, corporation, general or limited partnership, limited liability company, firm, joint venture, association, enterprise, joint securities company, trust, unincorporated organization or other entity is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement, other than fees payable by the Company to the Placement Agents, which will be paid by the Company. The Company agrees to indemnify each Purchaser for any claims, losses or expenses incurred by such Purchaser as a result of the Company’s representation in this Section 7 being untrue.

SECTION 8. COVENANTS.

8.1 Blue Sky Filings. The Company will take such action as the Company shall reasonably determine is necessary in order to obtain an exemption from, or to qualify the Shares for, sale to the Purchasers at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon the written request of any Purchaser.

8.2 Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income taxes) that are required to be paid in connection with the issuance, sale and delivery of the Shares to the Purchasers hereunder will be fully paid or provided for by the Company and all laws imposing such taxes will have been fully complied with and the Purchasers and their respective Affiliates shall have no obligation therefor.

8.3 Listing of Ordinary Shares. The Company shall promptly secure the listing of the Shares upon the Trading Market and each other national securities exchange and automated quotation system that requires an application by the Company for listing, if any, upon which the Ordinary Shares are then listed (subject to official notice of issuance) and shall maintain such listing, so long as any other Ordinary Shares shall be so listed. The Company shall use its reasonable best efforts to maintain the Ordinary Shares’ listing on the Trading Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 8.3.

8.4 Equal Treatment of Purchasers. No consideration (including any modification of documents related hereto) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement or any documents related hereto unless the same consideration is also offered to all Purchasers hereunder. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class (subject to the proviso in the preceding sentence) and shall not in any way be construed as the Purchasers acting in concert or as a group (including a “group” within the meaning of Section 13(d)(3) of the Exchange Act) with respect to the purchase, disposition or voting of securities or otherwise. The Company does not have, and will not enter into, any agreement or understanding with any Purchaser that affords such Purchaser any rights or terms with respect to the

transactions contemplated by this Agreement (including the exhibits hereto) that are more beneficial to such Purchaser than those afforded to all other Purchasers hereunder.

8.5 Pledge of Shares. The Company acknowledges and agrees that a Purchaser’s Shares may be pledged by a Purchaser in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Shares. The pledge of Shares shall not be deemed to be a transfer, sale or assignment of the Shares hereunder, and no Purchaser effecting a pledge of Shares shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement; provided that a Purchaser and its pledgee shall be required to comply with the provisions of this Agreement in order to effect a sale, transfer or assignment of Shares to such pledgee.

8.6 Legend Removal. The Company shall, at its sole expense, upon appropriate notice from any Purchaser stating that Registrable Securities have been sold pursuant to an effective Secondary Registration Statement, under Rule 144, or any other exemption from the registration requirements under the Securities Act, within the earlier of (i) two (2) Trading Days and (ii) the Standard Settlement Period, in each case, of such notice, cause its transfer agent to timely prepare and deliver certificates or book-entry shares representing the Shares to be delivered to a transferee pursuant to such sale, which certificates or book-entry shares shall be free of any restrictive legends and in such denominations and registered in such names as such Purchaser may request. Further, the Company shall, at its sole expense, cause its legal counsel or other counsel satisfactory to the transfer agent: (i) while the Secondary Registration Statement is effective, to issue to the transfer agent a “blanket” legal opinion to allow sales without restriction pursuant to the effective Secondary Registration Statement, and (ii) provide all other opinions as may reasonably be required by the transfer agent in connection with the removal of legends. A Purchaser may request that the Company remove, and the Company agrees to authorize the removal of, any legend from such Shares, following the delivery by a Purchaser to the Company or the Company’s transfer agent of either a legended certificate representing such Shares or, if the Shares are issued in book-entry form, a written request for legend removal: (i) following any sale of such Securities pursuant to Rule 144 or any other applicable exemption from the registration requirements under the Securities Act, (ii) if such Shares are eligible for sale under Rule 144(b)(1), or (iii) following the time that the Secondary Registration Statement is declared effective. If a legend removal request is made pursuant to the foregoing, the Company will, no later than the earlier of (i) two (2) Trading Days and (ii) the Standard Settlement Period, in each case, following the delivery by a Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such Shares (or a request for legend removal, in the case of Shares issued in book-entry form), deliver or cause to be delivered to such Purchaser a certificate representing such Shares that is free from all restrictive legends or an equivalent book-entry position, as requested by the Purchaser. Certificates for Shares free from all restrictive legends may be transmitted by the Company’s transfer agent to a Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company (“DTC”) as directed by such Purchaser. The Company warrants that the Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement. If a Purchaser effects a transfer of the Shares in accordance with Section 5.11, the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Purchaser to effect such transfer. Each Purchaser hereby agrees that the removal of the restrictive legend pursuant to this Section 8.6 is predicated upon the Company’s reliance that such Purchaser will sell any such Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and such Purchaser shall deliver a certificate reasonably satisfactory to the Company to the foregoing effect. Prior to the Company and its transfer agent agreeing to a form of representation letter to be given in connection with any legend removal opinion, the Company shall allow each Purchaser to review such

form and shall cooperate, reasonably and in good faith, and accept reasonable comments thereto from the Purchasers; and provided, further, that in no event shall the Purchaser be required to agree to indemnify, defend or hold harmless any Person.

SECTION 10. MISCELLANEOUS.

10.1 Waivers and Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged, terminated, modified or amended except upon the written consent of the Company and, if prior to the Closing, Purchasers that have subscribed for at least a majority of the Shares to be issued hereunder, and, if after the Closing, Purchasers holding at least a majority of the Shares issued hereunder and then held by all Purchasers, in the case of any change, discharge, termination, modification, or of the party hereto against whom the waiver is to be effective, in the case of a waiver, provided that (a) if any amendment or waiver disproportionately and adversely affects a Purchaser (or a subset of Purchasers) in any material respect, the consent of such disproportionately affected Purchaser (or each Purchaser within such subset of Purchasers) shall also be required and (b) the consent of each Purchaser shall be required for any change in the Purchase Price, any change in the type of security to be issued to Purchasers at Closing, or the amendment, modification or waiver of this Section 10.1, of Section 10.14, of Section 6, or of any of the closing conditions set forth in Sections 3.2(b)(i), 3.2(b)(iii) or 3.2(b)(v). No waiver of any default with respect to any provision, condition or requirement of this

Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. The failure of any party at any time to require another party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation.

10.2 Headings; Interpretation. The headings of the various sections of this Agreement have been inserted for convenience of reference only and shall not be deemed to be part of this Agreement. The terms “hereof,” “herein,” “hereby” and derivative or similar words refer to this Agreement as a whole and not to any particular provision of this Agreement. Except when used together with the word “either” or otherwise for the purpose of identifying mutually exclusive alternatives, the term “or” has the inclusive meaning represented by the phrase “and/or.” All references in this Agreement to “dollars” or “$” shall mean United States dollars. Except where the context otherwise requires, wherever used the singular shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders. The term “including” or “includes” means “including without limitation” or “includes without limitation.”

10.3 Severability. In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

10.4 Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Shares. The agreements and covenants contained herein shall survive for the applicable statute of limitations.

10.5 Governing Law; Jurisdiction. This Agreement shall be governed by and interpreted in accordance with the substantive laws of the State of New York, without regard to its or any other jurisdiction’s choice of law rules. Any and all disputes arising out of, concerning, or related to this Agreement, or to the interpretation, performance, breach or termination thereof shall be referred to and resolved by the federal courts located in New York, New York or, to the extent no such court does not have subject matter jurisdiction, the state courts of the State of New York located in New York, New York (the “Specified Courts”). Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the Specified Courts, waives any objection to the laying of venue of any suit, action or proceeding brought in such courts and waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SHARES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

10.6 Counterparts. This Agreement may be executed in counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other party. Signatures to this Agreement transmitted by email in “portable document format” (“.pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of this Agreement (including, without limitation, DocuSign) shall have the same effect as physical delivery of the paper document bearing original signature.

10.7 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. None of the Purchasers may assign this Agreement or any rights or obligations hereunder, in whole or in part, without the prior written consent of the Company; provided, however, that a Purchaser may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of the Shares in a transaction complying with applicable securities laws without the prior written consent of the Company, provided such assignee agrees in writing to be bound by the provisions hereof that apply to Purchasers. The Company may not assign this Agreement or any rights or obligations hereunder, in whole or in part, without the prior written consent of all Purchasers. Without limiting the generality of the foregoing, in the event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Ordinary Shares are converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Shares” shall be deemed to refer to the securities received by the Purchasers in exchange therefor in connection with such transaction. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

10.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and the Placement Agents and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 6.3 and this Section 10.8. Notwithstanding the foregoing, the Placement Agents shall be the third-party beneficiaries of the representations and warranties of the Company in Section 4 of this Agreement and the representations and warranties of the Purchasers in Section 5 of this Agreement. The parties further agree that the Placement Agents may rely on or, if the Placement Agents so request, be specifically named as an addressee of, the legal opinion to be delivered pursuant to this Agreement.

10.9 Entire Agreement. This Agreement and the other documents and instruments delivered pursuant hereto or thereto, including the exhibits and schedules hereto or thereto, constitute the full and entire understanding and agreement between the parties hereto with regard to the subjects hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof, provided, that any written confidentiality agreement that the Company and any Purchaser entered into in contemplation of entering into this Agreement, shall survive in accordance with its terms and provisions.

10.10 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. The decision of each Purchaser to purchase Shares pursuant to this

Agreement has been made by such Purchaser independently of any other Purchaser. Nothing contained herein and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group (within the meaning of Section 13(d) of the Exchange Act or otherwise), or are deemed affiliates (as such term is defined under the Exchange Act) with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser acknowledges (i) that it is not relying upon any Person other than the Company and its officers and directors, in making its investment or decision to invest in the Company and (ii) no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Shares or enforcing its rights hereunder. Each Purchaser agrees that no Purchaser nor the respective controlling persons, officers, directors, partners, agents, or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares. The Company acknowledges that each of the Purchasers has been provided with the same Agreement for the purpose of closing a transaction with multiple purchasers and not because it was required or requested to do so by any Purchaser. It is expressly understood that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

10.11 Payment of Fees and Expenses. Except as otherwise provided herein or in the other documents or instruments contemplated hereby, each of the Company and the Purchasers shall bear its own expenses and legal fees incurred on its behalf with respect to this Agreement and the transactions contemplated hereby.

10.12 Further Actions. Each party hereto agrees to execute, acknowledge, and deliver such further instruments, and to do all such other acts, as may be reasonably necessary or appropriate in order to carry out the purposes and intent of this Agreement.

10.13 Securities Law Disclosure. By no later than 9:00 A.M., New York City time, on the Trading Day immediately following the Effective Date, the Company shall issue a press release and/or file a Current Report on Form 8-K with the Commission (the “Disclosure Document”) disclosing all material terms of the transactions contemplated by this Agreement; provided, that each of the Purchasers and Placement Agents shall be given a reasonable opportunity to review and comment on the disclosure contained in the Disclosure Document prior to issuance or filing. In addition, unless it has already done so by filing the Disclosure Document, on or before the fourth (4th) Business Day following the Effective Date, the Company shall file a Current Report on Form 8-K with the Commission disclosing all material terms of the transactions contemplated by this Agreement. From and after the issuance of the Disclosure Document, no Purchaser shall be in possession of any material non-public information received from the Company or from any other representative of the Company in connection with the transactions contemplated by this Agreement, except in the case of information that may have been provided pursuant to any confidentiality agreement between the Company and a Purchaser or agreement between the Placement Agents and such Purchaser, provided, that to the extent that such information constitutes material non-public information of the Company, the Company covenants and agrees to publicly release such information no later than 9:00 a.m. (New York time) on March 30, 2026, upon which time such Purchaser shall no longer be in possession of any material non-public information of the Company. Except for the Disclosure Document and the Current Report on Form 8-K contemplated by this Section

10.13, all public announcements regarding this Agreement shall be issued only in accordance with Section 10.15.

10.14 Termination. This Agreement (a) shall be terminated automatically if the Closing has not been consummated on or prior to the fifth Business Day from the Effective Date, or (b) may be terminated by a Purchaser (with respect to itself) if any of the conditions set forth in Section 3.2(a) or Section 3.2(b) shall have become incapable of fulfillment, and shall not have been waived by such Purchaser, provided, however, that no such termination will affect the right of any party to sue for any breach by the other party (or parties), and, upon such termination pursuant to this Section 10.14, any purchase price wired to the Company by a Purchaser shall be promptly returned to the Purchaser, but in no event later than the first Trading Day following such termination.

10.15 Placement Agents. The Company agrees that the Placement Agents, their affiliates and their representatives shall be entitled to (a) rely on, and shall be protected in acting upon, any certificate, instrument, opinion, notice, letter or any other document or security delivered to any Placement Agents or any Purchaser by or on behalf of the Company, and (b) be indemnified by the Company for acting as Placement Agents in accordance with the indemnification provisions set forth in the Engagement Letter.

RE: Connect Biopharma Holdings Limited – Lock-up Agreement

Ladies & Gentlemen:

The undersigned is a record or beneficial owner of ordinary shares of Connect Biopharma Holdings Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands (the “Company”), $0.000174 par value per share, (the “Ordinary Shares”). The Company proposes to issue and sell Ordinary Shares to certain purchasers pursuant to the Securities Purchase Agreement dated on or about the date hereof by and among the Company and such purchasers (the “Purchase Agreement”), in connection with which Leerink Partners LLC and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ & Co. are expected to act as the placement agents (the “Placement Agents”). The undersigned recognizes that the proposed issuance and sale of the Ordinary Shares will benefit each of the Company and the undersigned. The undersigned acknowledges that the Placement Agents are relying on the representations and agreements of the undersigned contained in this letter agreement (this “Letter Agreement”) in connection with the proposed issuance and sale of the Ordinary Shares.

Annex A sets forth definitions for capitalized terms used in this Letter Agreement that are not defined in the body of this Letter Agreement. Those definitions are a part of this Letter Agreement.

In consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees that, during the Lock-up Period (as defined below), the undersigned will not (and will cause any Family Member not to), without the prior written consent of the Placement Agents, which may withhold their consent in their sole discretion:

•directly or indirectly Sell or Offer to Sell any Ordinary Shares or Related Securities currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Exchange Act) by the undersigned or such Family Member,

•enter into any Swap,

•make any demand for, or exercise any right with respect to, the registration under the Securities Act of the offer and sale of any Ordinary Shares or Related Securities, or cause to be filed a registration statement, prospectus or prospectus supplement (or an amendment or supplement thereto) with respect to any such registration, or

•publicly announce any intention to do any of the foregoing.

The foregoing will not apply to the offer and sale of the Ordinary Shares to the purchasers or the registration for resale of the Ordinary Shares sold to the purchasers, in each case as contemplated by the Purchase Agreement. In addition, the foregoing restrictions shall not apply to:

(i)the transfer of Ordinary Shares or Related Securities by gift, including, without limitation, to a charitable organization, or by will or intestate succession to the legal representative, heir, beneficiary or any Family Member or to a trust whose beneficiaries consist exclusively of one or more of the undersigned and/or a Family Member;

(ii)any transfer or disposition of Ordinary Shares or Related Securities acquired in the transaction contemplated by the Purchase Agreement or on the open market following such transaction, provided that no public disclosure or filing under the Exchange Act (other than filings under Section 13 of the Exchange Act) by any party to the transfer shall be required, or made voluntarily, during the Lock-up Period;

(iii)transfers or dispositions of the undersigned’s Ordinary Shares or Related Securities to any corporation, partnership, limited liability company or other entity all of the beneficial ownership interests of which, in each case, are held by the undersigned or any Family Member;

(iv)transfer of Ordinary Shares or Related Securities by operation of law, including pursuant to a domestic order or divorce settlement;

(v)if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, the transfer of Ordinary Shares or Related Securities to (x) another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act) of the undersigned, (y) any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned, or (z) limited partners, general partners, members, managers, managing members, directors, officers, employees, stockholders or other equity holders of the undersigned or of the entities described in the preceding clauses (x) and (y);

(vi)the exercise of stock options granted under any equity incentive plans of the Company by the undersigned, and the receipt by the undersigned from the Company of Ordinary Shares upon such exercise, insofar as such option is outstanding as of the date of the Purchase Agreement, provided that the underlying Ordinary Shares shall continue to be subject to the restrictions on transfer set forth in this Letter Agreement, and provided further, if required, any public report or filing shall clearly indicate in the footnotes thereto that the filing relates to the exercise of a stock option and that no Ordinary Shares were sold by the reporting person;

(vii)transfers of Ordinary Shares to the Company as forfeitures (x) to satisfy tax withholding and remittance obligations of the undersigned in connection with the vesting or exercise of equity awards granted pursuant to the Company’s equity incentive plans or (y) pursuant to a net exercise or cashless exercise by the stockholder of outstanding equity awards pursuant to the Company’s equity incentive plans, provided that any Ordinary Shares received as a result of such exercise, vesting or settlement shall remain subject to the terms of this Letter Agreement, and provided further, if required, any public report or

filing shall clearly indicate in the footnotes thereto that such transfer is being made pursuant to the circumstances described in this clause (vii);

(viii)the transfer of Ordinary Shares or Related Securities pursuant to a change of control of the Company (meaning the consummation of any bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of Ordinary Shares the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, becomes the beneficial owner (as defined in

Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the voting capital stock of the Company) after the completion of the offering contemplated by the Purchase Agreement that has been approved by the independent members of the Company’s board of directors, provided, that in the event that such change of control is not completed, the Ordinary Shares or Related Securities owned by the undersigned shall remain subject to the terms of this Letter Agreement;

(ix)the transfer of Ordinary Shares or Related Securities to the Company in connection with the repurchase of such Ordinary Shares or Related Securities upon the termination of the undersigned’s employment with the Company pursuant to a contractual agreement between the undersigned and the Company as in effect as of the date of the Purchase Agreement; or

(x)the transfer or disposition of Ordinary Shares pursuant to a trading plan established in accordance with Rule 10b5-1 under the Exchange Act that has been entered into by the undersigned prior to the date of the Purchase Agreement.

Notwithstanding the foregoing, in any such case as provided in clauses (i), (iii), (iv) and (v), it shall be a condition to such transfer that:

•each transferee executes and delivers to the Placement Agents an agreement in form and substance satisfactory to the Placement Agents stating that such transferee is receiving and holding such Ordinary Shares and/or Related Securities subject to the provisions of this Letter Agreement and agrees not to Sell or Offer to Sell such Ordinary Shares and/or Related Securities, engage in any Swap or engage in any other activities restricted under this Letter Agreement except in accordance with this Letter Agreement (as if such transferee had been an original signatory hereto), and

•prior to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange Act by any party to the transfer (donor, donee, transferor or transferee) shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Ordinary Shares or Related Securities in connection with such transfer, other than with respect to a transfer pursuant to a gift made in accordance with clause (i), in which case the undersigned may file a report required by Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership of Ordinary Shares as a result of such gift, provided that such report shall include a statement in such report to the effect that, such transfer is being made as a gift.

Furthermore, notwithstanding the restrictions imposed by this Letter Agreement, the undersigned may establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Ordinary Shares, provided that such plan does not provide for any transfers of Ordinary Shares during the Lock-up Period and the entry into such plan is not publicly disclosed, including in any filing under the Exchange Act, during the Lock-up Period.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Ordinary Shares and/or Related Securities held by the undersigned and the undersigned’s Family Members, if any, except in compliance with the foregoing restrictions.

The undersigned hereby represents and warrants that the undersigned has full power, capacity and authority to enter into this Letter Agreement. This Letter Agreement is irrevocable and will be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned.

This Letter Agreement may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

The undersigned understands that the undersigned shall be released from all obligations under the Letter Agreement if the Purchase Agreement is terminated prior to the Closing (as defined in the Purchase Agreement).

This Letter Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
