become Vested Shares in substantially equal installments determined from the Initial Vesting Date at the periodic rate set forth in the Grant Notice, with the last such installment vesting on the last “Full Vest” date set forth in the Grant Notice.

1.2 Construction.  Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement.  Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular.  Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

2. Certain Conditions of the Option.

2.1 Compliance with Local Law.  The Participant agrees that the Participant will not acquire shares pursuant to the Option or transfer, assign, sell or otherwise deal with such shares except in compliance with Local Law.

2.2 Special Conditions Applicable to the People’s Republic of China.  The following terms and conditions are applicable only to residents of the People’s Republic of China:

(a) Cashless Exercise Procedure.  The Participant acknowledges that in order to comply with Local Law, the Option may be exercised only by means of a “Cashless Exercise,” as described in Section 4.3 below.  By accepting this Option and in order to implement the Cashless Exercise procedure, the Participant hereby:

(i) irrevocably appoints the Company as the Participant’s agent to instruct a brokerage firm designated by the Company (the “Brokerage Firm”) to sell on behalf of the Participant at the prevailing market price on the Option exercise date (or on the next trading day if the exercise date is not a day on which the markets are open for trading) the shares of Stock issuable to the Participant upon the exercise of the Option; and

(ii) authorizes and directs the Company to deposit the shares of Stock sold upon the exercise of the Option with the Brokerage Firm in accordance with Section 4.5; and

(iii) irrevocably assigns to the Company or any other Participating Company out of the proceeds of such sale of shares an amount equal to the sum of the aggregate Exercise Price of the shares for which the Option is being exercised and the Tax Obligations required to be withheld in accordance with Section 4.4, and authorizes the Company to instruct the Brokerage Firm to pay to the Company the amount of such aggregate Exercise Price and to pay to the Company or another Participating Company an amount equal to the Tax Obligations required to be withheld; and

(iv) authorizes and directs the Company to instruct the Brokerage Firm to deliver the proceeds of such sale of shares, net of brokerage commissions, fees, aggregate Exercise Price and Tax Obligations withheld, to the Company for the benefit of the Participant and to be deposited to a designated custodial account for payment to the Participant; and

(v) authorizes the Company and any other Participating Company to provide to the Brokerage Firm information regarding the details of the Option and the Tax Obligations, and authorizes the Brokerage Firm to provide to the Company and any other Participating Company confirmation of the details of the sale of the shares of Stock.

(b) Special Administration.  The grant and vesting of the Option and the Participant’s ability to receive funds upon the sale of shares to be issued upon the exercise of the Option, as described above, will be contingent upon the Company or its Affiliate obtaining approval from the State Administration of Foreign Exchange (“SAFE”) of the People’s Republic of China for the related foreign exchange transaction and the establishment of a SAFE-approved bank account.  The receipt of funds by the Participant from the sale of the shares and the conversion of those funds to the local currency must be approved by SAFE.  In order to comply with the SAFE regulations, the proceeds from the sale of the shares must be repatriated to China through a SAFE-approved bank account established and monitored by the Company or its Affiliate.

2.3 Employment Conditions.  In accepting the Option, the Participant acknowledges that:

(a) Any notice period mandated under Local Law shall not be treated as Service for the purpose of determining the vesting of the Option; and the Participant’s right to exercise the Option after termination of Service, if any, will be measured by the date of termination of the Participant’s active Service and will not be extended by any notice period mandated under Local Law.  Subject to the foregoing and the provisions of the Plan, the Company, in its sole discretion, shall determine whether the Participant’s Service has terminated and the effective date of such termination.

(b) The vesting of the Option shall cease upon, and no shares shall become Vested Shares following, the Participant’s termination of Service for any reason except as may be explicitly provided by the Plan or this Agreement.

(c) The Plan is established voluntarily by the Company.  It is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the Plan and this Option Agreement.

(d) The grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of Options, or benefits in lieu of Options, even if Options have been granted repeatedly in the past.

(e) All decisions with respect to future Option grants, if any, will be at the sole discretion of the Company.

(f) The Participant’s participation in the Plan shall not create a right to further Service with any Participating Company and shall not interfere with the ability of any Participating Company to terminate the Participant’s Service at any time, with or without cause.

(g) The Participant is voluntarily participating in the Plan.

(h) The Option is an extraordinary item that does not constitute compensation of any kind for Service of any kind rendered to any Participating Company, and which is outside the scope of the Participant’s employment contract, if any.

(i) The Option is not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation,  termination,  redundancy, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

(j) In the event that the Participant is not an employee of the Company, the Option grant will not be interpreted to form an employment contract or relationship with the Company; and furthermore the Option grant will not be interpreted to form an employment contract with any other Participating Company.

(k) The future value of the underlying shares is unknown and cannot be predicted with certainty.  If the underlying shares do not increase in value, the Option will have no value.  If the Participant exercises the Option and obtains shares, the value of those shares acquired upon exercise may increase or decrease in value, even below the Exercise Price.

(l) No claim or entitlement to compensation or damages arises from termination of the Option or diminution in value of the Option or shares purchased through exercise of the Option resulting from termination of the Participant’s Service (for any reason whether or not in breach of Local Law) and the Participant irrevocably releases the Company and each other Participating Company from any such claim that may arise.  If, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen then, by signing this Option Agreement, the Participant shall be deemed irrevocably to have waived the Participant’s entitlement to pursue such a claim.

2.4 Data Privacy Consent.

(a) The Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of the Participant’s personal data as described in this document by and among the members of the Participating Company Group for the exclusive purpose of implementing, administering and managing the Participant’s participation in the Plan.

(b) The Participant understands that the Participating Company Group holds certain personal information about the Participant, including, but not limited to, the Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares or directorships held in the Company, details of all Options or any other entitlement to shares awarded, canceled, exercised, vested, unvested or outstanding in the Participant’s favor, for the purpose of implementing, administering and managing the Plan (“Data”).  The Participant understands that Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in the Participant’s country or elsewhere, and that the recipient’s country may have different data privacy laws and protections than the Participant’s country.  The Participant understands that he or she may request a list

with the names and addresses of any potential recipients of the Data by contacting the Participant’s local human resources representative.  The Participant authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Participant’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Participant may elect to deposit any shares acquired upon exercise of the Option.  The Participant understands that Data will be held only as long as is necessary to implement, administer and manage the Participant’s participation in the Plan.  The Participant understands that he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Participant’s local human resources representative.  The Participant understands, however, that refusing or withdrawing the Participant’s consent may affect the Participant’s ability to participate in the Plan.  For more information on the consequences of the Participant’s refusal to consent or withdrawal of consent, the Participant understands that he or she may contact the Participant’s local human resources representative.

3. Administration.

4. Exercise of the Option.

4.1 Right to Exercise.  Except as otherwise provided herein, the Option shall be exercisable on and after the Initial Vesting Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option.  In no event shall the Option be exercisable for more shares than the Number of Option Shares, as adjusted pursuant to Section 9.

4.2 Method of Exercise.    Exercise of the Option shall be by means of electronic or written notice (the “Exercise Notice”) in a form authorized by the Company.  An electronic Exercise Notice must be digitally signed or authenticated by the Participant in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company).  In the event that the Participant is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be

signed by the Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company).  Each Exercise Notice, whether electronic or written, must state the Participant’s election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Participant’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement.  Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate Exercise Price for the number of shares of Stock being purchased.  The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price.

4.3 Payment of Exercise Price.    Payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised may be made only by means of a Cashless Exercise.  A “Cashless Exercise” means the delivery of a properly executed Exercise Notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the aggregate Exercise Price for such shares (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).    In addition, the Cashless Exercise shall be implemented as described in Section 2.2 above.

4.4 Tax Withholding.

(a) In General.    Regardless of any action taken by the Company or any other Participating Company with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (the “Tax Obligations”), the Participant acknowledges that the ultimate liability for all Tax Obligations legally due by the Participant is and remains the Participant’s responsibility and that the Company (a) makes no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Option, including the grant, vesting or exercise of the Option, the subsequent sale of shares acquired pursuant to such exercise, or the receipt of any dividends and (b) does not commit to structure the terms of the grant or any other aspect of the Option to reduce or eliminate the Participant’s liability for Tax Obligations.  At the time of exercise of the Option, the Participant shall pay or make adequate arrangements satisfactory to the Company to satisfy all withholding obligations of the Company and any other Participating Company.  In this regard, at the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company or any other Participating Company, the Participant hereby authorizes withholding of all applicable Tax Obligations from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for withholding of all applicable Tax Obligations, if any, by each Participating Company which arise in connection with the Option.  Alternatively, or in addition, if permissible under applicable law, including Local Law, the Company or any other Participating Company may sell or arrange for the sale of shares acquired by the Participant to satisfy the Tax Obligations.  Finally, the Participant shall pay to the Company or any other Participating Company any amount of the Tax Obligations that any

such company may be required to withhold as a result of the Participant’s participation in the Plan that cannot be satisfied by the means previously described.  The Company shall have no obligation to process the exercise of the Option or to deliver shares until the Tax Obligations as described in this Section have been satisfied by the Participant.

(b) Assignment of Sale Proceeds.  Subject to compliance with applicable law, including Local Law, and the Company’s Trading Compliance Policy, the Company may require the Participant to satisfy the Tax Obligations in accordance with procedures established by the Company providing for delivery by the Participant to the Company or a broker approved by the Company of properly executed instructions, in a form approved by the Company, providing for the assignment to a Participating Company of the proceeds of a sale with respect to some or all of the shares being acquired upon the exercise of the Option.

(c) Withholding in Shares.    .  If permissible under applicable law, including Local Law, the Company shall have the right, but not the obligation, to require the Participant to satisfy all or any portion of the Tax Obligations upon exercise of the Option by deducting from the shares of Stock otherwise issuable to the Participant upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such Tax Obligations determined by the applicable minimum statutory withholding rates if required to avoid liability classification of the Option under generally accepted accounting principles in the United States.

4.5 Beneficial Ownership of Shares; Certificate Registration.  The Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all shares acquired by the Participant pursuant to the exercise of the Option.  Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant.

4.6 Restrictions on Grant of the Option and Issuance of Shares.  The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities.  The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed.  In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act.  THE PARTICIPANT IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.  ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED.  The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve

the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained.  As a condition to the exercise of the Option, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

4.7 Fractional Shares.  The Company shall not be required to issue fractional shares upon the exercise of the Option.

5. Nontransferability of the Option.

6. Termination of the Option.

7. Effect of Termination of Service.

7.1 Option Exercisability.    The Option shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant’s termination of Service to the extent it is then vested only during the applicable time period as determined below and thereafter shall terminate.

(a) Disability.  If the Participant’s Service terminates because of the Disability of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of six  (6) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date.

(b) Death.    If the Participant’s Service terminates because of the death of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal representative or other person who acquired the right to exercise the Option by reason of the Participant’s death at any time prior to the expiration of six  (6) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 

The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant’s termination of Service.

(c) Termination for Cause.  Notwithstanding any other provision of this Option Agreement to the contrary, if the Participant’s Service is terminated for Cause or if, following the Participant’s termination of Service and during any period in which the Option otherwise would remain exercisable, the Participant engages in any act that would constitute Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service or act.

(d) Other Termination of Service.    If the Participant’s Service terminates for any reason, except Disability, death or Cause, the Option, to the extent unexercised and exercisable for Vested Shares by the Participant on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of three (3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date.

7.2 Extension if Exercise Prevented by Law.  Notwithstanding the foregoing, other than termination of the Participant’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until the later of (a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions, or (b) the end of the applicable time period under Section 7.1, but in any event no later than the Option Expiration Date.
