4.3 No Conflicts. The execution, delivery and performance of the Transaction Agreements and compliance with the provisions thereof by the Investor will not, with or without the passage of time or giving of notice: (i) conflict with or result in a violation of the certificate of incorporation, bylaws, or other organizational or constitutive documents of the Investor as in effect on the Closing Date, (ii) result in any violation of any Law or Order to which the Investor or any of its assets is subject, (iii) (A) conflict with or result in a breach, violation of, or constitute a default under, or (B) give any Third Party the right to modify, terminate or accelerate, or cause any modification, termination or acceleration of, any obligation under any Contract to which the Investor is a party, or (iv) result in the creation of any Lien upon any of the Investor’s assets or equity interests, except in the case of any of clauses (ii), (iii) and (iv) above, as would not reasonably be expected to materially impair of the ability of the Investor to perform its obligations under the Transaction Agreements and the transactions contemplated thereby in any material respect.

4.5 Investment Representations. The Investor acknowledges that the Shares have not been registered under the Securities Act or under any state or foreign securities laws. The Investor (i) acknowledges that it is acquiring the Shares pursuant to an exemption from registration under the Securities Act solely for investment with no present intention to distribute any of the

Shares to any person in violation of applicable securities Laws, (ii) will not Dispose of any of the Shares, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities Laws, (iii) has such knowledge and experience in financial and business matters and in investments of this type that it is capable of evaluating the merits and risks of its investment in the Shares and of making an informed investment decision, (iv) is an “accredited investor” (as that term is defined by Rule 501 of the Securities Act), and (v) (A) has been furnished with or has had full access to all the information that it considers necessary or appropriate to make an informed investment decision with respect to the Shares, (B) has had an opportunity to discuss with management of the Company the intended business and financial affairs of the Company and, in connection therewith, obtained information necessary to verify any information furnished to it or to which it had access (it being agreed and understood that this Clause (v) does not affect the Company’s representations and warranties contained in Section 3) and (C) can bear the economic risk of (x) an investment in the Shares indefinitely and (y) a total loss in respect of such investment.

(a) The Investor understands that the Shares shall be subject to restrictions on resale pursuant to applicable securities Laws and that any certificates representing the Shares or the applicable balance account of the Investor with the Company’s Transfer Agent shall bear transfer restrictions with the effect of the following applicable legend:

“These securities have not been registered under the Securities Act of 1933. They may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under the Securities Act or an opinion of counsel (which counsel shall be reasonably satisfactory to BeiGene, Ltd.) that such registration is not required or unless sold pursuant to Rule 144 of the Securities Act or an exemption from the registration requirements under the Securities Act.”

(b) The Shares shall not bear the transfer restrictions set forth in Section 4.6(a) hereof: (i) following a sale of Shares pursuant to an effective registration statement covering the resale of such Shares, (ii) following any sale of Shares pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”) (or any successor provision then in effect), or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC). Notwithstanding the foregoing, the Company shall direct the Transfer Agent to remove the transfer restriction set forth in Section 4.6(a) applicable to the Shares upon the written request of the Investor, within five (5) Business Days upon receipt of all documents required by the Transfer Agent, at such time as the

Shares may be transferred without such restriction under the Securities Act. If the Transfer Agent requires, the Investor or the Company, as applicable, shall provide such opinions of counsel (which counsel shall be reasonably acceptable to the Company) reasonably requested by the Transfer Agent in connection with the removal of legends pursuant to this Section 4.6(b). Any fees (with respect to the Transfer Agent, counsel to the Investor or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Investor.

Notwithstanding the foregoing, if (A) the Investor’s holding is not, or is no longer, subject to equity method accounting treatment in accordance with GAAP (other than as a result of the Investor’s sale of Company shares or the Investor’s failure to participate in future offerings or sales of New Securities in which Investor was given the opportunity to participate pursuant to Section 5.16), and (B) the Investor has used commercially reasonable efforts (in light of the trading price of the Company’s shares) to acquire additional equity securities of the Company sufficient to maintain equity method accounting treatment (subject to Section 5.1), including participating in offerings of New Securities pursuant to Section 5.16 to the extent permissible under applicable Law or acquiring equity securities of the Company in the open market or from shareholders of the Company, then (x) the lock-up provisions of this Section 5.2 shall not apply and (y) the sale limitations set forth in Section 5.5 may be exceeded but the Investor shall use reasonable best efforts to conduct such sales in a manner that minimizes the adverse effect of such sale on the public trading price of the Company’s shares, and the Investor and its Affiliates shall be entitled to Dispose of the shares referenced in clauses (a) and (b) above until the Investor’s ownership percentage of the Company reaches ten percent (10%) of the then outstanding share capital of the Company, at which point, the lock-up provisions of this Section 5.2 shall again apply with respect to the Investor and its Affiliates; provided, however, that before the Investor first Disposes of any such shares in accordance with the foregoing clause, the Investor shall provide ten (10) days prior written notice to the Company and shall, during such period, explore in good faith and in cooperation with the Company commercially reasonable alternatives in order to maintain its equity method accounting treatment in accordance with GAAP.

5.3 Voting of Securities. From and after the Closing Date until the later of (i) the fifth (5^th) anniversary of the Closing Date and (ii) the expiration of the Standstill Period, in any vote or action by written consent of the shareholders of the Company, except as provided by Section 5.4, the Investor shall, and shall cause its Affiliates to, vote or execute a written consent with respect to all voting securities of the Company as to which it is entitled to vote or execute a written consent (A) in accordance with the recommendation of a majority of the Company’s board of directors, including the Designated Director, solely with respect to (i) the election of directors, provided that such directors are unanimously recommended by the Company’s board of directors, excluding the Designated Director; (ii) the approval of the Company’s auditor; (iii) the approval of, on a non-binding, advisory basis, the compensation of the Company’s named executive officers; (iv) the approval of an increase to the number of shares reserved for issuance or the issuance of shares under the Plans; (v) within the parameters of Rule 13.36 of the HK Listing Rules, the approval of the granting of a share issue mandate to the Company’s board of directors to issue, allot or deal with unissued Ordinary Shares and/or American Depositary Shares up to the next annual general meeting of shareholders of the Company, subject to the conditions described in the Company’s definitive proxy statement; and (vi) subject to the Company’s compliance with Section 5.16, the authorization of the Company and its underwriters, in their sole discretion, to allocate to each of ▇▇▇▇▇ Bros. Advisors LP and ▇▇▇▇▇▇▇▇▇ Capital Management, Ltd. and parties affiliated with each of them (the “Existing Shareholders”), up to a maximum amount of shares

in order to maintain the same shareholding percentage of each of the Existing Shareholders (based on the then-outstanding share capital of the Company) before and after the allocation of the corresponding securities issued pursuant to an offering for a period of five years, which period will be subject to an extension on a rolling basis each year, conditional on the approval of the shareholders who are not Existing Shareholders, subject to the conditions described in the Company’s definitive proxy statement, provided that, to the extent permissible by the HK Listing Rules and subject to the Company’s ability to obtain any necessary waiver thereunder to seek shareholder approval therefor, any such authorization or a similar authorization provides for an allocation to the Investor in the same manner as the Existing Shareholders, and (B) in accordance with and proportional to the votes cast by shareholders entitled to vote other than the Investor, in any matter that arises as a result of a conflict due to the Collaboration Agreement.

In furtherance of this Section 5.3, the Investor shall, and shall cause its Affiliates to, if and when requested by the Company from time to time, promptly execute and deliver to the Company an irrevocable proxy, substantially in the form of Exhibit B attached hereto, and irrevocably appoint the Company or its designees, with full power of substitution, its attorney, agent and proxy to vote (or cause to be voted) or to give consent with respect to, all of the voting securities of the Company as to which the Investor or Affiliate of the Investor is entitled to vote, in the manner and with respect to the matters set forth in this Section 5.3. The Investor acknowledges, and shall cause its Affiliates to acknowledge, that any such proxy executed and delivered shall be coupled with an interest, shall constitute, among other things, an inducement for the Company to enter into this Agreement, shall be irrevocable and binding on any successor in interest of the Investor or Affiliate of the Investor, as applicable, and shall not be terminated by operation of Law upon the occurrence of any event. Such proxy shall operate to revoke and render void any prior proxy as to any voting securities of the Company heretofore granted by the Investor or its Affiliate, as applicable, to the extent it is inconsistent herewith. Notwithstanding the foregoing, the irrevocable proxy shall be effective if, at any annual or special meeting of the shareholders of the Company (or any consent in lieu thereof) and at any adjournments or postponements of any such meetings, the Investor (A) fails to appear or otherwise fails to cause its voting securities of the Company to be counted as present for purposes of calculating a quorum, or (B) fails to vote such voting securities in accordance with this Section 5.3, in each case at least five (5) Business Days prior to the proxy voting deadline for such shareholders’ meeting (or within five (5) Business Days prior to the proxy voting deadline for an action to be taken by written consent in lieu of such shareholders’ meeting). Such proxy shall terminate upon the later of (i) the fifth (5^th) anniversary of the Closing Date and (ii) the expiration of the Standstill Period.

5.4 Retained Voting Rights. For the avoidance of doubt, the Investor and its Affiliates may vote, or execute a written consent with respect to, any or all of the voting securities of the Company as to which they are entitled to vote or execute a written consent, as they may determine in their sole discretion with respect to any matter other than as described in Section 5.3.

5.5 Sale Limitations. Subject to the restrictions set forth in Section 5.2, following the later of (i) the expiration of the Lock-Up Period and (ii) the expiration of the Standstill Period, the Investor agrees that it shall not, and shall cause its Affiliates not to, Dispose of any Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents except (a) pursuant to a registered underwritten public offering in accordance with Section 5.11, (b) pursuant to Rule 144 under the Securities Act in accordance with the volume restrictions applicable thereto,

(c) in a private sale exempt from the registration requirements of the Securities Act, or (d) in any transaction approved by the Company; provided, however, that in no event shall the Dispositions in clauses (a), (b) or (c), in any rolling twelve (12)-calendar month period, exceed five percent (5%) of the then outstanding share capital of the Company (i) for as long as the Investor holds [***] or more of the then outstanding share capital of the Company and (ii) after the Investor holds less than [***] of the then outstanding share capital of the Company, for as long as (x) a Designated Director continues to serve on the Company’s Board of Directors or (y) the Company would be required to file a registration statement to effectuate the sale; and provided further, however, that in no event shall the Investor or any of its Affiliates Dispose of any Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents to any Person that the Investor or its Affiliate knows (after a reasonable inquiry in a non-public offering) is a Competitor or is an Activist Investor.

5.6 Offering Lock-Up. The Investor shall, if requested by the Company and an underwriter of Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents in connection with any public offering involving an underwriting of Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents, agree not to Dispose of any Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents for a specified period of time, such period of time not to exceed ninety (90) days (a “Lock-Up Agreement”); provided that such Lock-Up Agreement shall also be signed by all Company directors, officers and their respective affiliated stockholders (excluding [***]). Any Lock-Up Agreement shall be in writing in a form reasonably satisfactory to the Company and the underwriter(s) in such offering; provided, that if shareholders of the Company will be selling more Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents than the Company in such offering, then shareholders holding a majority of such Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents shall be responsible for negotiating the Lock-Up Agreement with the underwriter with respect to their Ordinary Shares not being sold in the public offering. The Company may impose stop transfer instructions with respect to the Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents subject to the foregoing restrictions until the end of the specified period of time. The foregoing provisions of this Section 5.6 shall not apply (a) if the Investor and its Affiliates collectively own less than five percent (5%) of Ordinary Shares or American Depositary Shares of the outstanding share capital of the Company or Ordinary Share Equivalents, (b) if the Investor ceases to have the right to appoint a Designated Director pursuant to Section 5.12, (c) to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall be applicable to the Investor only if all officers and directors are subject to the same restrictions or (d) if any beneficial owner of at least five percent (5%) of Ordinary Shares or American Depositary Shares of the then outstanding share capital of the Company or Ordinary Share Equivalents (excluding [***]) is not subject to a Lock-Up Agreement upon the same terms and conditions as the Investor.

5.7 Further Assurances. Subject to the terms and conditions of this Agreement, each of the Company and the Investor agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and assist the other party hereto in doing, all things reasonably necessary, proper or advisable to obtain prompt satisfaction of the conditions precedent to the consummation of the transactions contemplated at the Closing, and to comply with any regulatory requirements under the HK Listing Rules, including: (a) obtaining all necessary Consents and the making of all filings and the taking of all steps as may be necessary,

including convening any prerequisite meetings of bodies of the Company, to obtain a required Consent or avoid an Action by any Governmental Authority, (b) the defending of any Actions challenging this Agreement or any other Transaction Agreements or the consummation of the transactions contemplated hereby or thereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, (c) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement and the other Transaction Agreements, and (d) the Investor’s providing any information reasonably requested by the Company to allow it to publish public announcements and circulars regarding the Transaction Agreements and the transactions contemplated hereunder and thereunder pursuant to the HK Listing Rules and to respond to any queries raised by the HK Stock Exchange.

5.8 Securities Law Disclosure; Publicity. No public release or announcement concerning the transactions contemplated hereby or by any other Transaction Agreement shall be issued by the Company or the Investor without the prior consent of the Company (in the case of a release or announcement by the Investor) or the Investor (in the case of a release or announcement by the Company) (which consents shall not be unreasonably withheld, conditioned or delayed), except for any such release or announcement as may be required by securities Law or other applicable Law or the applicable rules or regulations of any securities exchange or securities market, in which case the Company or the Investor, as the case may be, shall (to the extent permissible under applicable Law) allow the Investor or the Company, as applicable, reasonable time to comment on such release or announcement in advance of such issuance and the disclosing party shall consider the other party’s comments in good faith. Notwithstanding the foregoing, following execution and delivery of this Agreement, the Company and the Investor shall each issue a separate press release substantially in the forms attached to the Collaboration Agreement, and the Investor and the Company may make one or more public filings attaching any Transaction Agreement pursuant to applicable securities Laws.

5.9 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) that would be integrated with the offer or sale of the Shares to be issued to the Investor hereunder for purposes of the rules and regulations of any of the following markets or exchanges on which the Common Shares or the Company is listed or quoted for trading on the date in question: the Pink OTC Markets, the OTC Bulletin Board, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global Select Market, the NYSE MKT or the New York Stock Exchange.

5.10 Notification. After the date hereof and prior to the Closing Date, the Company shall promptly deliver to the Investor a written notice of any event or development that would, or could reasonably be expected to, result in any condition to the Closing set forth in Section 6, not to be satisfied.

5.11 Registration Rights. The Company covenants and agrees as follows:

(a) If at any time after the expiration of the Lock-Up Period and continuing so long as the Investor holds Registrable Shares, the Company proposes to register any of its Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents under the Securities Act for sale to the public (other than a registration effected solely to implement an

Employee Benefit Plan or a transaction to which Rule 145 of the Securities Act is applicable, or a registration statement on Form ▇-▇, ▇-▇ or another form not available for registering the Registrable Shares for sale to the public), each such time it will give written notice to the Investor of its intention to do so. Upon the written request of the Investor given within twenty (20) days after receipt by the Investor of such notice, the Company shall, subject to the limits contained in this Section 5.11, use its reasonable best efforts to cause all such Registrable Shares of the Investor to be registered under the Securities Act and qualified for sale under any state securities or “blue sky” law, all to the extent required to permit such sale or other disposition of their Registrable Shares (a “Piggyback Registration”); provided, however, that if the Company is advised in writing in good faith by any managing underwriter of the Company’s Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents being offered in a public offering pursuant to such registration statement that the amount to be sold by Persons other than the Company who have been granted registration rights (collectively, “Selling Shareholders”) is greater than the amount that can be offered without adversely affecting the offering, (1) in an offering initiated by the Company and not pursuant to any registration rights granted to any Selling Shareholder, the Company shall be required to include in the offering only the number of such securities, including Registrable Shares, held by Selling Shareholders that the managing underwriter and the Company determine in their sole discretion shall not jeopardize the success of the offering, on a pro rata basis based on securities beneficially owned by the Selling Shareholders participating in such offering, and (2) in an underwritten, marketed offering initiated by any Selling Shareholders other than the Investor (such initiating Selling Shareholders, the “Initiating Shareholders”), the number of shares that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (i) first, the securities that the Company desires to include in such registration shall be excluded, (ii) second, securities of Selling Shareholders other than the Initiating Shareholders requested to be included in such registration shall be excluded, on a pro rata basis based on securities beneficially owned by such Selling Shareholders, and (iii) third, securities held by the Initiating Shareholders requested to be included in such registration shall be excluded, on a pro rata basis based on securities beneficially owned by the Initiating Shareholders. For the avoidance of doubt, in any sale of the Company’s securities not involving an underwritten, marketed offering or the participation of the Company (such as a block trade, even if the broker in such trade requests an agreement with the Company similar to what might be customarily considered an underwriting agreement), none of the Investor or any other shareholder of the Company shall be entitled to participate in such sale through a Piggyback Registration or otherwise.

(b) Following demand by the Investor (a “Demand Request”) at any time after the expiration of the Lock-Up Period (or any earlier termination or waiver by the Company thereof), or such earlier time as the Company in its sole discretion may agree in writing, the Company shall, subject to the limits contained in this Section 5.11, file with the SEC a registration statement on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Shares on Form S-3, in which case such registration shall be on another appropriate form in accordance with the Securities Act) covering the resale of the Registrable Shares (a “Demand Registration”), and the Company shall file such registration statement as promptly as reasonably practicable following such Demand Request, and in any event within sixty (60) days of such Demand Request; provided, however, that in an underwritten, marketed offering initiated by the Investor, if the Company is advised in writing in good faith by any managing underwriter of the Company’s Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents

being offered in a public offering pursuant to such registration statement that the amount to be sold by Selling Shareholders is greater than the amount that can be offered without adversely affecting the offering, the number of shares that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (i) first, the securities that the Company desires to include in such registration shall be excluded, (ii) second, securities of Selling Shareholders other than Registrable Shares requested to be included in such registration shall be excluded, on a pro rata basis based on securities beneficially owned by such Selling Shareholders, and (iii) third, Registrable Shares requested to be included in such registration shall be excluded. Notwithstanding the foregoing, the Company shall not be obligated to effect any Demand Registration of Registrable Shares upon receipt of a Demand Request pursuant to this Section 5.11(b) if:

(i) the Company has, within the twelve (12)-month period preceding the date of the Demand Request, already (x) effected two (2) Demand Registrations pursuant to this Section 5.11(b) with no reduction in the number of Registrable Shares requested to be included in such registration or (y) effected Demand Registrations registering Registrable Shares representing, in the aggregate, five percent (5%) of the then outstanding share capital of the Company;

(ii) the market value of the Registrable Shares proposed to be included in the registration, based on the average closing price during the ten (10) consecutive trading days period prior to the making of the Demand Request, is less than one hundred million dollars ($100,000,000); or

(iii) the Registrable Shares proposed to be included in the registration exceed five percent (5%) of the then outstanding share capital of the Company.

(c) The underwriter for any Demand Registration requested pursuant to Section 5.11(b) shall be selected by Investor and shall be reasonably acceptable to the Company. The Company shall participate in the marketing of any Registrable Shares offered by the Investor under any Demand Registration as reasonably requested by the Investor. All expenses incurred in connection with registrations, filings or qualifications pursuant to this Section 5.11, including all registration, filing and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees and disbursements, shall be borne and paid by the Company. The Company shall use its reasonable best efforts to cause the registration statement for any Demand Registration and related prospectuses to become effective as promptly as practicable after filing. The Company shall use its reasonable best efforts to cause such registration statement to remain effective under the Securities Act until the earlier of the date (i) all Registrable Shares covered by such registration statement have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant to Rule 144 or (ii) all Registrable Shares covered by such registration statement otherwise cease to be Registrable Shares pursuant to this Agreement. The Company shall promptly, and within two business days after the Company confirms effectiveness of such registration statement with the SEC, notify the Investor of the effectiveness of such registration statement. Except as otherwise set forth in Section 5.11(a) and Section 5.11(b), for the avoidance of doubt, in no way will any registration rights granted hereunder be deemed to limit the Company’s obligations in respect of registration rights previously granted to any other shareholder of the Company in an agreement that has been filed in the Company SEC Documents.

(d) For the purposes of this Section 5.11,

(i) “Losses” means any loss, damage, claim or liability (joint or several) or actions in respect thereof to which a party hereto may become subject, insofar as such loss, damage, claim or liability or action in respect thereof arises out of or is based upon: (A) any untrue statement or alleged untrue statement of a material fact contained in any registration statement of the Company registering the resale of the Registrable Shares, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or any issuer free writing prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, (B) an omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading or (C) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance.

(ii) “Registrable Shares” means the Shares held by Investor and the Deposit Shares relating thereto, including, without limitation, any Ordinary Shares or American Depositary Shares paid, issued or distributed in respect of any such Shares or Deposit Shares by way of stock dividend, stock split or distribution, or in connection with a combination of shares, recapitalization, reorganization, merger or consolidation, or otherwise, but excluding Ordinary Shares or American Depositary Shares acquired before or after the Closing Date, provided, however, that the Shares and the Deposit Shares relating thereto, will not be “Registrable Shares” (A) after the Shares or Deposit Shares have been sold pursuant to an effective registration statement or in compliance with Rule 144 or other exemptions from registration or (B) when the remaining Shares or Deposit Shares held by the Investor may be resold by the Investor in a single transaction without the volume and manner of sale limitations under Rule 144.

(e) With a view to making available to the Investor the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit the Investor to sell Registrable Shares to the public without registration, during the twelve (12) month period following the Closing Date, the Company covenants that it will use reasonable best efforts to:

(i) file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder;

(ii) make and keep public information available information necessary to comply with Rule 144 with respect to resales of the Shares or Deposit Shares under the Securities Act, at all times, to the extent required from time to time to enable the Investor to resell Shares or Deposit Shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 (if available with respect to resales of the Shares or Deposit Shares), as such rule may be amended from time to time;

(iii) prior to the filing of a registration statement or any amendment thereto (whether pre-effective or post-effective), and prior to the filing of any prospectus or prospectus supplement related thereto, provide the Investor with copies of all of the pages thereof (if any) that reference the Investor; and

(iv) furnish to the Investor, so long as the Investor owns any Registrable Shares, forthwith upon request (a) a written statement by the Company that it has complied with the reporting requirements of Rule 144, (b) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company with the SEC, and (c) such other information as may be reasonably requested by the Investor in availing itself of any rule or regulation of the SEC which permits an Investor to sell any such securities without registration.

(f) To the extent permitted by law, the Company shall indemnify the Investor, and, as applicable, its officers, directors, and constituent partners, legal counsel for the Investor and each Person controlling the Investor, with respect to which registration, related qualification, or related compliance of Registrable Shares has been effected pursuant to this Agreement, and each underwriter, if any, and each Person who controls any underwriter within the meaning of the Securities Act against all claims, losses, damages, or liabilities (or actions in respect thereof) to the extent such claims, losses, damages, or liabilities arise out of or are based upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus or other document (including any related registration statement) incident to any such registration, qualification, or compliance, or (ii) any 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 state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance; and the Company shall pay as incurred to the Investor, each such underwriter, and each Person who controls the Investor or underwriter, any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action; provided, however, that the indemnity contained in this Section 5.11(f) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability, or action if settlement is effected without the consent of the Company (which consent shall not unreasonably be withheld); and provided, further, that the Company shall not be liable in any such case to the extent that any such claim, loss, damage, liability, or expense arises out of or is based upon any untrue statement or omission contained in such prospectus or other document based upon written information furnished to the Company by the Investor, such underwriter, or such controlling Person and stated to be for use therein.

(g) To the extent permitted by law, the Investor shall, if Registrable Shares held by the Investor are included for sale in the registration and related qualification and compliance effected pursuant to this Section 5.11, indemnify the Company, each of its directors, each officer of the Company who signs the applicable registration statement, each legal counsel and each underwriter of the Company’s securities covered by such a registration statement, each Person who controls the Company or such underwriter within the meaning of the Securities Act against all claims, losses, damages, and liabilities (or actions in respect thereof) arising out of or

based upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, or related document, or (ii) any 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 Investor of the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to such Investor and relating to action or inaction required of the Investor in connection with any such registration and related qualification and compliance, and shall pay as incurred to such persons, any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in (and such violation pertains to) such registration statement or related document in reliance upon and in conformity with written information furnished to the Company by such Investor and stated to be specifically for use therein; provided, however, that the indemnity contained in this Section 5.11(g) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability, or action if settlement is effected without the consent of the Investor (which consent shall not unreasonably be withheld); provided, further, that the Investor’s liability under this Section 5.11(g) (when combined with any amounts such Investor is liable for under Section 5.11(i)) shall not exceed the Investor’s net proceeds from the offering of securities made in connection with such registration.

(h) Promptly after receipt by an indemnified party under this Section 5.11 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 5.11, notify the indemnifying party in writing of the commencement thereof and generally summarize such action. The indemnifying party shall have the right to participate in and to assume the defense of such claim; provided, however, that the indemnifying party shall be entitled to select counsel for the defense of such claim with the approval of any parties entitled to indemnification, which approval shall not be unreasonably withheld; provided further, however, that if either party reasonably determines that there may be a conflict between the position of the Company and the Investor in conducting the defense of such action, suit, or proceeding by reason of recognized claims for indemnity under this Section 5.11, then counsel for such party shall be entitled to conduct the defense to the extent reasonably determined by such counsel to be necessary to protect the interest of such party. The failure to notify an indemnifying party promptly of the commencement of any such action, if prejudicial to the ability of the indemnifying party to defend such action, shall relieve such indemnifying party, to the extent so prejudiced, of any liability to the indemnified party under this Section 5.11, but the omission so to notify the indemnifying party shall not relieve such party of any liability that such party may have to any indemnified party otherwise than under this Section 5.11.

(i) If the indemnification provided for in this Section 5.11 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable

considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined 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. In no event, however, shall (i) any amount due for contribution hereunder be in excess of the amount that would otherwise be due under Section 5.11(f) or Section 5.11(g), as applicable, based on the limitations of such provisions and (ii) a Person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) be entitled to contribution from a Person who was not guilty of such fraudulent misrepresentation.

(j) In the case of each registration of Registrable Shares effected by the Company pursuant to this Section 5.11, the Company shall keep the Investor advised as to the initiation of each such registration and as to the status thereof. The Company shall use its reasonable best efforts, within the limits set forth in this Section 5.11(j), to:

(i) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectuses used in connection with such registration statement as may be necessary to keep such registration statement effective and current and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(ii) furnish to the Investor such numbers of copies of a prospectus, including preliminary prospectuses, in conformity with the requirements of the Securities Act, and such other documents as the Investors may reasonably request in order to facilitate the disposition of Registrable Securities;

(iii) register and qualify the Registrable Shares covered by such registration statement under such other securities or blue sky laws of such jurisdictions in the United States as shall be reasonably requested by the Investor, 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;

(iv) 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 of such offering and take such other usual and customary action as the Investor may reasonably request in order to facilitate the disposition of such Registrable Shares;

(v) notify the Investor at any time when a prospectus relating to a registration statement covering any Registrable Shares is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company shall use its reasonable best efforts to amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit 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;

(vi) provide a transfer agent and registrar for all Registrable Shares registered pursuant to such registration statement and, if required, a CUSIP number for all such Registrable Shares, in each case not later than the effective date of such registration;

(vii) if requested by the Investor, use reasonable best efforts to cause the Company’s transfer agent to remove any restrictive legend from any Registrable Shares being transferred by the Investor pursuant to a registration statement, within five (5) business days upon receipt of all required documents by the Transfer Agent;

(viii) cause to be furnished, at the request of the Investor, on the date that Registrable Shares are delivered to underwriters for sale in connection with an underwritten offering pursuant to this Agreement, (A) an opinion, dated 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, addressed to the underwriters, and (B) a letter or letters 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, addressed to the underwriters;

(ix) participate in any marketing, meeting with a potential investor, road show or comparable activity that may be reasonably required to complete the orderly sale of shares by the underwriter or underwriters; and

(x) cause all such Registrable Shares included in a registration statement pursuant to this Agreement to be listed on each securities exchange or other securities trading markets on which American Depositary Shares representing Ordinary Shares are then listed.

(k) The obligations of the Company and the Investor under this Section 5.11 shall survive the completion of any offering of Registrable Shares in a registration statement under this Agreement or otherwise.

5.12 Designated Director.

(a) During the period beginning on the Closing Date and ending on the earlier of (i) the date as of which the Investor holds less than ten percent (10%) of the then outstanding share capital of the Company as a result of the Investor’s sale of Shares or the Investor’s failure to participate in future offerings or sales of New Securities in which Investor is given the opportunity to participate pursuant to Section 5.16(a) and (ii) the third (3^rd) anniversary of the date of the expiration or termination of the Collaboration Agreement (the “Board Term”), the Investor may, upon written notice to the Company, direct the Company to cause one individual selected by the Investor who is an independent director under applicable Laws (including the listing standards of any stock exchange on which the Company’s securities are then traded) reasonably satisfactory to the Company and who satisfies the Company’s then-published director qualification criteria (the “Designated Director”) to be appointed as a member of the Company’s board of directors within ten (10) days after the Company’s receipt of such written notice and to

thereafter be nominated for re-election by the shareholders of the Company; provided that the initial Designated Director shall be appointed as of the Closing Date; provided further, that, with respect to the initial Designated Director and any new Designated Director, if the Company rejects [***] individuals pursuant to this Section 5.12, the Investor shall thereafter nominate, and the Company shall appoint, an individual who is not a full-time employee of the Investor or any of its Affiliates, who is an independent director under applicable Laws (including the listing standards of any stock exchange on which the Company’s securities are then traded) and who satisfies the Company’s then-published director qualification criteria. The Designated Director shall be required to complete and sign the Company’s standard form of director & officer questionnaire prior to appointment and at each time it is requested of the Company’s other directors, and personally enter into a non-disclosure agreement with the Company and shall be bound by the Company’s code of conduct and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy. In connection with each subsequent meeting of the shareholders of the Company at which the Designated Director’s term of service as a director is expiring, the Company shall cause the Designated Director to be nominated for re-election at such meeting and included within the slate of directors contained in the Company’s proxy statement, accompanied by a recommendation by the Company’s board of directors that such individual be elected as a director. In the event the Designated Director is nominated for re-election at a meeting of the shareholders of the Company but is not re-elected by the shareholders, the Company’s obligations pursuant to this Section 5.12 shall terminate with respect to such individual. Notwithstanding the foregoing sentence, in the event a Designated Director is not re-elected by the shareholders, the Investor retains the right to appoint a new Designated Director in accordance with this Section 5.12, and the Company’s obligations pursuant to this Section 5.12 remain in effect with respect to such new Designated Director. In the event a vacancy is created at any time by the death, disability, retirement, resignation or removal of a Designated Director, the Investor may, upon written notice to the Company, direct the Company to promptly appoint a new Designated Director to fill the resulting vacancy. Any Designated Director shall sign a resignation letter which shall become effective as of the end of the Board Term.

(b) The Company shall notify the Designated Director of all regular and special meetings of the Company’s board of directors or any committee thereof of which the Designated Director is a member. Subject to the following sentence, the Company shall provide the Designated Director with copies of all notices, minutes, consents and other materials provided to all other directors (the “Director Information”) concurrently as such materials are provided to the other directors. The Designated Director will be afforded no less favorable treatment than any other member of the Company’s Board of Directors with respect to all matters, including, without limitation, assistance with filings to be made with the SEC pursuant to Section 16 of the Exchange Act and other required regulatory filings, expense reimbursement and indemnification consistent with those offered to all other members of the Company’s Board of Directors and reasonable access to Company information and management, except that (i) the Designated Director shall not be entitled to receive compensation for service as a member of the Company’s board of directors if such Designated Director is a full-time employee of the Investor or any of its Affiliates; (ii) the Designated Director may be excluded from participation or deliberation by the Company’s board of directors or committees thereof upon the request of the Chairman of the board of directors after consultation with the Company’s internal or external legal advisors if and solely to the extent any matter is to be presented or discussed in which the Investor has an actual conflict of interest; and (iii) the Designated Director shall not have the right to receive Director Information with respect to the matters noted in clause (ii) of this sentence.

5.13 PFIC Reporting. For so long as the Investor holds Shares or Deposit Shares, the Company hereby agrees to use reasonable best efforts to cause the Company and each of its controlled subsidiaries to not be treated as a PFIC and to reasonably cooperate with the Investor in order to permit the Investor to determine whether the Company is at any time a PFIC. In furtherance of the foregoing, the Company shall notify the Investor if, in good faith, the Company reasonably believes the Company was a PFIC during the prior taxable year, provided that the publication of a PFIC Annual Information Statement by the Company on the Company’s website shall be deemed to satisfy such notification requirement. If the Company determines that the Company is a PFIC, the Company shall use reasonable best efforts to (i) provide such information to the Investor as the Investor may reasonably request to enable the Investor to complete its U.S. Internal Revenue Service Form 8621 with respect to the Company and any PFIC in which the Company owns an interest, any stock of which is treated as owned by the Investor pursuant to Section 1298(a) of the Code, and (ii) provide such statements, information and documentation as the Investor reasonably believes is necessary for it to make an election to treat each such entity as a “qualified electing fund” under Section 1295 of the Code and to determine the Investor’s foreign tax credits under Section 1293(f) of the Code.

5.14 Controlled Foreign Corporation. For so long as the Investor holds Shares or Deposit Shares at any point during a taxable year, then the Company hereby agrees to reasonably cooperate with the Investor in order to permit the Investor to determine whether the Company is a CFC. If the Company is or is likely to have become a CFC, then the Company shall use reasonable best efforts to provide to the Investor such information as it may reasonably request to assist the Investor to timely comply with its filing obligations under the Code, including but not limited to Internal Revenue Service Form 5471.

5.15 Deposit of Shares and Issuance of American Depositary Receipts. Upon the written request of the Investor to the Company, the Company will deposit or cause to be deposited such number of Shares with the Depositary Agent as is requested by the Investor, and issue or cause to be issued to the Investor the American Depositary Receipts representing the corresponding American Depositary Shares, with any and all costs associated with such deposit and issuance paid for by the Investor. The Company shall (a) use its reasonable best efforts to (i) register or qualify such American Depositary Shares under the securities or blue sky Laws of such jurisdictions in the United States as the Investor reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable the Investor to consummate the disposition in such jurisdictions of the American Depositary Shares owned by the Investor and (ii) cause all such American Depositary Shares to be eligible and remain eligible for registration of the American Depositary Shares pursuant to Form F-6, and (b) cooperate with the Investor and the Depositary Agent to facilitate the timely delivery of American Depositary Shares (in book entry or certificated form), which American Depositary Shares shall be free of all restrictive legends unless the Company reasonably determines on advice from legal counsel that such legends are required by applicable law (it being understood that the American Depositary Shares may be restricted American Depositary Shares subject to restrictions imposed by the Depositary Agent for so long as the Investor is an Affiliate).

5.16 Subsequent Issuances.

(a) If the Company proposes to offer or sell any Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents after the Closing Date, other than pursuant to the Plans (“New Securities”), and at the time immediately prior to such offer or sale the Investor holds no more than twenty point five percent (20.5%) of the Company’s outstanding share capital, the Company shall use reasonable best efforts to provide the Investor with an opportunity to participate in such offering or sale and purchase upon the same terms and conditions as other purchasers in the offering or sale of the New Securities, up to that portion of such New Securities as is necessary to allow the Investor to hold twenty point five percent (20.5%) of the Company’s share capital after the sale of New Securities, so long as the Investor’s ownership percentage prior to such sale has not decreased as a result of the Investor’s sale of Shares or the Investor’s failure to participate in future offerings or sales of New Securities in which Investor is given the opportunity to participate pursuant to this Section 5.16(a), subject to applicable Law and HK Listing Rules. As soon as reasonably practicable following the resolution of any comments referenced in Section 5.18(a) with respect to the Proxy Statement (as defined below), the Company will use reasonable best efforts to request and obtain a waiver from the HK Listing Rules and obtain shareholder approval, if required, to permit the foregoing, provided that the Company shall not be required to seek or obtain shareholder approval in advance of or as a condition to an offering or sale of any of its Ordinary Shares, American Depositary Shares or Ordinary Share Equivalents; provided, further, that if the Company shall seek to request and obtain a waiver from the HK Listing Rules and obtain shareholder approval for the issuance of New Securities to the Existing Shareholders, the Company shall do the same in the same manner for the Investor.

(b) Subject to Section 5.16(c) and notwithstanding anything else to the contrary in this Agreement, in the event that the Investor or the Company receives a second request or other inquiry under the HSR Act or from any regulatory authority such that the Closing is not reasonably expected to occur on January 1, 2020, then, prior to the Closing the Company may offer and sell New Securities in a follow-on public offering in an amount of up to $1 billion in aggregate gross proceeds, exclusive of any customary underwriter over-allotment option (a “Follow-On Offering”). Subject to applicable Law, the Company shall provide Investor with an opportunity to purchase twenty point five percent (20.5%) of such New Securities (the “Incremental Shares”) in such Follow-On Offering at a purchase price per Incremental Share equal to the per share price that is paid by the other purchasers in the Follow-On Offering (the “Per Incremental Share Purchase Price”), and otherwise upon the same terms and conditions as the other purchasers in the Follow-On Offering. If the Investor does not purchase the Incremental Shares in the Follow-On Offering, then the Investor shall purchase the Incremental Shares at a purchase price per Incremental Share equal to the Per Incremental Share Purchase Price, at the Closing, together with the Shares at the Per Share Purchase Price.

(c) Notwithstanding Section 5.16(b) or anything else to the contrary in this Agreement:

(i) Any filing, release or other public disclosure or announcement made in connection with any Follow-On Offering and concerning Investor shall be in a form reasonably satisfactory to the Investor, and Company shall allow the Investor reasonable time to comment on any such filing, release or other public disclosure or announcement.

(ii) No Follow-On Offering, if any, shall be permitted if it would reasonably be expected (A) to prevent, delay or otherwise interfere with the Closing or any other transactions contemplated by this Agreement or the Collaboration Agreement, (B) adversely affect the ability of the Company to perform its obligations under the Collaboration Agreement, or (C) adversely affect the ability of the Company to perform its obligations under this Agreement.

5.17 Use of Proceeds. Until the expiration or termination of the Collaboration Agreement, the Company shall use the gross proceeds from the sale of the Shares as necessary to fund its development obligations under the Collaboration Agreement; provided that, subject to the Company’s co-development and other obligations set forth in the Collaboration Agreement (including additional development of commercial products), the Company shall not be obligated to use more than the lesser of (i) [***] and (ii) [***], to fund its development obligations under the Collaboration Agreement. Until the third (3rd) anniversary of the Effective Date, the Company shall not use the proceeds from the purchase of the Shares to declare a cash dividend to its shareholders or to purchase any outstanding Ordinary Shares, except for re-purchases of shares issued under the Plans.

5.18 Preparation of Proxy; Shareholders Meeting; Board Recommendation.

(a) As promptly as reasonably practicable after the execution of this Agreement, the Company shall prepare and cause to be filed with the SEC and/or the HK Stock Exchange, as applicable, a proxy statement relating to the Shareholder Approval (such proxy statement, and any amendments or supplements thereto, the “Proxy Statement”). The Investor shall furnish all information concerning the Investor and its Affiliates to the Company, as may be reasonably requested by the Company to be included in the Proxy Statement and shall otherwise assist and cooperate with the Company in the preparation of the Proxy Statement and the resolution of any comments to the Proxy Statement received from the SEC or HK Stock Exchange, as applicable. Both the Company and the Investor shall promptly correct any information provided by it for use in the Proxy Statement if and to the extent such information becomes false or misleading in any material respect. The Company shall notify the Investor upon the receipt of any comments from the SEC or HK Stock Exchange, as applicable, and of any request by the SEC or HK Stock Exchange, as applicable, for amendments or supplements to the Proxy Statement. The Company shall use its reasonable best efforts to (i) respond as promptly as reasonably practicable to any comments received from the SEC or HK Stock Exchange, as applicable, concerning the Proxy Statement and to resolve such comments with the SEC or HK Stock Exchange, as applicable, and (ii) to cause the Proxy Statement to be disseminated to its shareholders as promptly as reasonably practicable after the resolution of any such comments.

(b) The Company shall take all necessary actions in accordance with applicable Law, the governing documents of the Company and the rules of NASDAQ and the HK Stock Exchange, as applicable, to duly call, give notice of, convene and hold a special shareholders meeting (the “Meeting”) for the purpose of obtaining the Shareholder Approval, as soon as reasonably practicable after the SEC or HK Stock Exchange, as applicable, confirms that it has no further comments on the Proxy Statement. Notwithstanding any provision of this Agreement to the contrary, the Company may adjourn, recess or postpone the Meeting (i) to the extent necessary

to ensure that any required supplement or amendment to the Proxy Statement is provided to the shareholders of the Company within a reasonable amount of time in advance of the Meeting, (ii) if as of the time for which the Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of capital stock of the Company represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Meeting or (iii) as may be required by applicable Law.

(c) The Company shall, through its board of directors, recommend to its shareholders the approval of all proposals set forth in the Shareholder Approval, and include such recommendation in the Proxy Statement. The board of directors of the Company shall not withdraw, amend, qualify or modify its recommendation to the shareholders of Company that they vote in favor of the proposals set forth in the Shareholder Approval, unless, in the opinion of counsel (which counsel shall be reasonably satisfactory to the Investor), the directors’ fiduciary duties would require them to take such action.

5.19 Reasonable Access. The Company will permit Investor and its representatives to have reasonable access at reasonable times to the premises, properties, personnel, books, records and documents of or pertaining to the Company and its Subsidiaries as is reasonably necessary in order to (a) prepare or make any filing or other submission to any Governmental Authority or other Person required in order to consummate the transactions contemplated hereby, (b) make SEC filings on a timely basis and conduct such other corporate activities, including tax, accounting and finance activities, related to Investor’s ownership interest in the Company and/or (c) keep Investor reasonably informed with respect to material events affecting the Company and/or its Subsidiaries. So long as the Investor holds at least twenty percent (20%) of the outstanding share capital of the Company, the Company shall promptly provide the Investor and its representatives with all information reasonably requested to maintain the Investor’s equity method accounting treatment in accordance with GAAP

5.20 Economic Substance. For so long as the Investor holds Shares or Deposit Shares, the Company shall, and shall cause its controlled subsidiaries to, use reasonable best efforts to comply with the International Tax Co-operation (Economic Substance) Law, 2018, of the Cayman Islands so that it does not become a defunct company and is not struck off.

8.3 Reserved.

8.4 Governing Law; Waiver of Jury Trial.

The parties irrevocably and unconditionally submit to the exclusive jurisdiction of the United States District Court for the Southern District of New York solely and specifically for the purposes of any action or proceeding arising out of or in connection with this Agreement, provided that the courts of the Cayman Islands shall have exclusive jurisdiction over the Cayman Law Matters. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES THAT JURISDICTION AND VENUE IN ANY SUIT, ACTION OR PROCEEDING BROUGHT BY ANY PARTY ARISING OUT OF OR RELATING TO THIS AGREEMENT (INCLUDING ANY SUIT, ACTION OR PROCEEDING SEEKING EQUITABLE RELIEF) SHALL PROPERLY AND EXCLUSIVELY LIE IN THE STATE AND FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK OR, IN ACCORDANCE WITH THIS SECTION 8.4, THE COURTS OF THE CAYMAN ISLANDS (THE “CHOSEN COURTS”).

EACH PARTY HERETO ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTIES HERETO THAT THIS SECTION 8.4 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THEY ARE RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT. ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 8.4 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

8.5 Survival. The representations, warranties, covenants and agreements made herein shall survive the Closing.

8.6 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon the parties hereto and their respective successors, assigns, heirs, executors and administrators and shall inure to the benefit of and be enforceable by each person who shall be a holder of the Shares from time to time; provided,

however, that prior to the receipt by the Company of adequate written notice of the transfer of any Shares specifying the full name and address of the transferee, the Company may deem and treat the person listed as the holder of such Shares in its records as the absolute owner and holder of such Shares for all purposes. This Agreement may not be assigned by any party hereto without the consent of the other party, provided, that the Investor may assign its rights and obligations hereunder in whole or in part to any Affiliate of the Investor or to any successor of the Investor as a result of a Change of Control of the Investor, provided further, that in the case of such assignment the assignee shall agree in writing to be bound by the provisions of this Agreement and the Investor shall not be relieved of its obligations hereunder.

8.7 Entire Agreement. This Agreement, the exhibits and schedules hereto, the other Transaction Agreement, and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable for or bound to any other in any manner by any oral or written representations, warranties, covenants and agreements except as specifically set forth herein and therein.

8.8 Severability. In the event one or more of the provisions of this Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. Upon such determination that any provision of this Agreement, or the application of any such provision, is invalid, illegal, void or unenforceable, the Company and the Investor shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Company and the Investor as closely as possible to the fullest extent permitted by Law in an acceptable manner to the end that the transactions contemplated hereby and the other Transaction Agreements are fulfilled to the greatest extent possible.

8.9 Amendment. No provision in this Agreement shall be supplemented, deleted or amended except in a writing executed by an authorized representative of each of the Investor and the Company. Any amendment effected in accordance with this Section 8.9 shall be binding upon each holder of Shares or Deposit Shares purchased under this Agreement at the time outstanding, each future holder of all such Shares or Deposit Shares, and the Company, and any amendment not effected in accordance with this Section 8.9 shall be void and of no effect.

8.10 Waivers; Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any Consent of any kind or character on any party’s part of any breach, default or noncompliance under this Agreement or any waiver on such party’s part of any provisions or conditions of the Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.

8.11 Equitable Relief. Each of the Company and the Investor hereby acknowledges and agrees that the failure of the Company or the Investor to perform their respective agreements and covenants hereunder will cause irreparable injury to the Investor or the Company, for which damages, even if available, will not be an adequate remedy. Accordingly, each of the Company and the Investor hereby agrees that the Investor and the Company shall be entitled to seek the issuance of equitable relief by any court of competent jurisdiction to compel performance of the Company’s or the Investor’s obligations.

EXHIBIT A

FORM OF SUPPORT AGREEMENT

THIS SUPPORT AGREEMENT (“Agreement”), dated as of October [●], 2019, is made by and between Amgen Inc., a Delaware corporation (the “Investor”), and the undersigned holder (the “Shareholder”) of ordinary shares, par value $0.0001 per share (“Ordinary Shares”), of BeiGene, Ltd., an exempted company incorporated in the Cayman Islands (the “Company”).

WHEREAS, the Investor and the Company have entered into (i) a Share Purchase Agreement, dated as of even date herewith (as such agreement may be subsequently amended or modified, the “Purchase Agreement”), providing for the sale and issuance by the Company to the Investor of [•] Ordinary Shares, and (ii) a Collaboration Agreement by and among the Company, BeiGene Switzerland GmbH, a wholly-owned subsidiary of the Company (“BeiGene Switzerland” and together with the Company, “BeiGene”), and the Investor (the “Collaboration Agreement”), subject in each case to the approval of the Company’s shareholders in accordance with the HK Listing Rules (collectively, the “Transaction”);

WHEREAS, as of the date hereof, the Shareholder beneficially owns and has sole or shared voting power with respect to the number of Ordinary Shares, and holds stock options or other rights to acquire beneficial ownership (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the number of Ordinary Shares indicated opposite the Shareholder’s name on Schedule 1 attached hereto (together with any New Shares (defined in Section 2 below), the “Shares”);

WHEREAS, as an inducement and a condition to the willingness of the Investor to enter into the Purchase Agreement and the Collaboration Agreement, and in consideration of the substantial expenses incurred and to be incurred by it in connection therewith, the Shareholder has agreed to enter into and perform this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Purchase Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, the Investor entering into the Purchase Agreement and the Collaboration Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by the Investor in connection therewith, the Shareholder and Investor agree as follows:

1. Agreement to Vote Shares. The Shareholder agrees that, prior to the Expiration Date (as defined in Section 2 below), at any meeting of the shareholders of the Company (such meeting, the “Company Shareholders’ Meeting”) or any adjournment or postponement thereof, or in connection with any written consent of the shareholders of the Company, with respect to the Transaction or the Purchase Agreement or the Collaboration Agreement, the Shareholder shall:

(a) appear at such Company Shareholders’ Meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) from and after the date hereof until the Expiration Date, vote (or cause to be voted), or deliver a written consent (or cause a written consent to be delivered) covering all of the Shares that such Shareholder shall be entitled to so vote: (i) in favor of approval of the Transaction and all other transactions contemplated by the Purchase Agreement or the Collaboration Agreement as to which shareholders of the Company are called upon to vote or consent in favor of any matter necessary for consummation of the Transaction and the other transactions contemplated by the Purchase Agreement or the Collaboration Agreement; and (ii) against any action or agreement that would reasonably be expected to prevent, materially impede or materially delay the consummation of the transactions contemplated by the Purchase Agreement or the Collaboration Agreement. The Shareholder shall not take or commit or agree to take any action inconsistent with the foregoing.

Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earlier to occur of (a) the date of the approval of the Transaction and all other transactions contemplated by the Purchase Agreement or the Collaboration Agreement at the Company Shareholders’ Meeting, (b) such date and time as the Purchase Agreement shall be terminated pursuant to Section 8.1 thereof, or (c) upon mutual written agreement of the parties to terminate this Agreement. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, such termination or expiration shall not relieve any party from liability for any fraud, willful breach of this Agreement or acts of bad faith prior to termination hereof.

Additional Purchases The Shareholder agrees that any Ordinary Shares of the Company that the Shareholder purchases or with respect to which the Shareholder otherwise acquires beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) after the execution of this Agreement and prior to the Expiration Date, whether by the exercise of any stock options or otherwise (“New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof. The Shareholder agrees to promptly notify Investor in writing of the nature and amount of any New Shares.

Transfers of Shares. From and after the date hereof until the Expiration Date, the Shareholder shall not, directly or indirectly, (a) deposit any Shares into a voting trust or enter into a voting agreement or similar arrangement with respect to such Shares or grant any proxy or power of attorney with respect thereto, (b) take any action that would make any representation or warranty of the Shareholder contained herein untrue or incorrect, or (c) take any action that would have the effect of preventing or disabling the Shareholder from performing the Shareholder’s obligations under this Agreement, provided that, with respect to the forgoing clause (b), any change to Schedule 1 hereto that is permitted by this Agreement shall not constitute a breach of clause (b). Notwithstanding the forgoing, nothing herein will limit or affect the Shareholder’s ability to directly or indirectly, (a) sell, assign, transfer, tender, or otherwise dispose of (including, without limitation, by the creation of a Lien (as defined in Section 5(c) below)) any Shares or (b) enter into any contract, option, commitment or other arrangement or understanding with respect to the direct or indirect sale, transfer, assignment or other disposition of (including, without limitation, by the creation of a Lien (as defined in Section 5(c) below)) any Shares.

2. Representations and Warranties of the Shareholder. The Shareholder hereby represents and warrants to Investor as follows:

(a) the Shareholder has the full power and authority to execute and deliver this Agreement and to perform the Shareholder’s obligations hereunder;

8. Severability. If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

10. No Waivers.
