2.    Rights as a Stockholder. The Holder shall not be entitled to any privileges of ownership with respect to the shares of Stock subject to the Award unless and until, and only to the extent, such shares become vested pursuant to Section 3 and delivered pursuant to Section 4 hereof and the Holder becomes a stockholder of record with respect to such shares. For the avoidance of doubt, the Holder shall have no beneficial interest or ownership in the vested shares of Stock until the issue or delivery of those vested shares to the Holder, and all restrictions applying to the Award pursuant to Section 3 shall continue until the delivery of the Stock pursuant to Section 4. The Award includes a right to dividend equivalents equal to the value of any dividends paid on the Stock for which the dividend record date occurs between the Grant Date and the date the Award is settled or forfeited. Subject to vesting of the underlying shares of Stock, each dividend equivalent entitles the Holder to receive the equivalent cash value of any such dividends paid on the number of shares of Stock underlying the Award that are outstanding during such period.

6.    Additional Terms and Conditions of Award.

6.1.    Withholding Taxes.

(a)    Regardless of any action the Company (including, for the avoidance of doubt, the entity directly employing the Holder, the “Employer”)) takes with respect to any or all international, US federal, state or local tax including all income tax, social insurance, social security contributions (where applicable), payroll tax, payment on account or other tax-related items arising out of the Holder’s participation in the Plan and legally applicable or deemed applicable to the Holder in any jurisdiction (“Required Tax Payments”) and subject to applicable laws, the Holder acknowledges that the ultimate liability for all Required Tax Payments is and remains the Holder’s responsibility and may exceed the amount actually withheld by the Company and/or the Employer, if any. The Holder further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Required Tax Payments in connection with any aspect of the Award or underlying shares of Stock, including, but not limited to, the grant, vesting or settlement of the Award, the subsequent sale of shares of Stock acquired upon the expiration of the Restriction Period and the receipt of any dividends and/or dividend equivalents; and (ii) do not commit and are under no obligation to structure the terms of the grant or any aspect of the restricted stock unit to reduce or eliminate the Holder’s liability for Required Tax Payments or achieve any particular tax result. Furthermore, if the Holder has become subject to tax in more than one jurisdiction, the Holder acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Required Tax Payments in more than one jurisdiction.

(b)    As a condition precedent to the delivery to the Holder of any Stock subject to the Award, the Holder shall, upon request by the Company and/or the Employer, pay to the Company and/or the Employer (or shall cause a broker-dealer on behalf of the Employee to pay to the Company and/or the Employer) such amount of cash as the Company and/or the Employer may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over Required Tax Payments with respect to the Award. If the Holder shall fail to advance the Required Tax Payments after request by the Company and/or the Employer, the Company and/or the Employer may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company and/or the Employer to the Holder.

(c)    Under the terms of this Agreement, the Holder’s obligations to pay the Required Tax Payments shall be satisfied by the Company withholding whole shares of Stock which would otherwise be issued or transferred to the Holder having an aggregate Fair Market Value, determined as of the date on which such withholding obligation arises (the “Tax Date”), equal to the Required Tax Payments, and the Holder will be deemed to have been issued the full number of shares of Stock subject to the vested portion of the Award, notwithstanding that a number of the shares is held back solely for the purpose of paying the Required Tax Payments due as a result of any aspect of the Holder’s participation in the Plan; provided, however, the Holder may notify the Company prior to the Tax Date that the Holder has elected, in lieu of the Company withholding shares of Stock, to satisfy his or her obligation to advance the Required Tax Payments by (i) a check or cash payment to the Company, (ii) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole shares of Stock having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments, (iii) except as may be prohibited by applicable law, a cash payment by a broker whom the Company has selected for this purpose and to whom the Holder has authorized to sell any shares acquired upon the vesting of the Award to meet the Required Tax Payments; or (iv) any combination of share withholding and (i), (ii) and (iii). Shares to be delivered to the Company or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments (or such greater withholding amount to the extent permitted by applicable withholding rules and accounting rules without resulting in variable accounting treatment). Any fraction of a share which would be required to satisfy any such obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder.

The Company shall withhold or account for Required Tax Payments by considering applicable minimum statutory withholding amounts (or, if requested by the Holder and permitted by the Board or the Committee, other applicable withholding rates, including maximum applicable rates in the Holder’s jurisdiction(s)). In the event of over-withholding, the Holder may receive a refund of any over-withheld amount in cash, or if not refunded, the Holder may seek a refund from the local tax authorities. In the event of under-withholding, the Holder may be required to pay additional Required Tax Payments directly to the applicable tax authority or to the Company and/or the Employer. The Holder shall pay to the Company or the Employer any amount of Required Tax Payments that the Company or the Employer may be required to withhold or account for as a result of the Holder’s participation in the Plan that cannot be satisfied by the means previously described in this section. The Company may refuse to issue or deliver the shares of Stock or the proceeds of the sale of shares to the Holder if the Holder fails to comply with its obligations in connection with the Required Tax Payments.

(d)    The Holder hereby agrees that they are liable for all Required Tax Payments and hereby covenants to pay all such Required Tax Payments, as and when requested by the Company or, if different, the Holder’s employer or by any tax authority in any relevant jurisdiction. The Holder hereby agrees to indemnify and keep indemnified the Company and, if different, the Holder’s employer against any Required Tax Payments that the Holder is required to pay or withhold or have paid or will pay to any other tax authority or any other relevant authority on the Holder’s behalf.

6.2.    Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the shares of Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares hereunder, the shares of Stock subject to the Award shall not be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

6.3.    Award Confers No Rights to Continued Employment. In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement or the Plan, give or be deemed to give the Holder any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.

6.4.    Decisions of Board or Committee. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award.

In order for the Chinese Holder to participate in the Plan, the Company will collect his or her personal data for purposes of allocating Stock and implementing, administering and managing the Plan.
