(b) The Option Holder is subscribing for the Shares hereunder for its own account with the present intention of holding such Shares for purposes of investment, and that it has no intention of selling such Shares in a public distribution in violation of any applicable U.S. federal or state securities laws.

(c) The Option Holder is not resident in the United States and is acquiring the Shares in an offshore transaction under Rule 903 of the U.S. Securities Act of 1933, as amended.

(e) Each of this letter agreement and the Shareholders Agreement has been duly executed and delivered by the Option Holder and, assuming due authorization, execution and delivery by the Company and the other parties thereto, constitutes a valid and binding obligation of the Option Holder, enforceable against the Option Holder in accordance with its terms, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether considered in a proceeding in equity or at law).

(f) Neither the execution, delivery or performance of this letter agreement or the Shareholders Agreement by the Option Holder nor the consummation by the Option Holder of the transactions contemplated hereby or thereby shall violate any law applicable to the Option Holder.

5. Tax Matters. The Option Holder agrees to bear and pay, and reimburse, indemnify and hold harmless the Company, Parent, Merger Subsidiary and, after the Effective Time, the Surviving Corporation, and any Affiliate thereof (collectively, the “Indemnified Parties”) for, from and against any and all liability for Taxes imposed or assessed on any Indemnified Party under any applicable PRC Law (or an official interpretation thereof) (collectively, “PRC Taxes”) arising from or attributable to the Option Holder’s failure to pay or remit, or any Indemnified Party’s failure to withhold or failure to assist in withholding from payments to the Option Holder any PRC Taxes arising from (i) any of the transactions contemplated by this letter agreement or the Merger Agreement, including receipt of the Shares by the Option Holder in exchange for the cancellation of the Option Amount pursuant hereto or (ii) any compensation (including stock, equity or equity-linked compensation) paid or granted to the Option Holder prior to the Effective Time (the matters described in clauses (i)-(ii) above, collectively, “Tax Liabilities”).

The Option Holder further agrees and acknowledges that, upon any determination by a Governmental Authority that any PRC Taxes are incurred or assessed on any Indemnified Party, arising from or attributable to any Tax Liabilities, or that any filing or registration is required in connection with any Tax Liabilities, the Option Holder shall promptly, pursuant to such determination, (i) pay any such PRC Taxes and other amounts owed by it, (ii) make any such filings or registrations with respect to such PRC Taxes and other amounts, and (iii) cooperate in good faith with the Surviving Corporation and its Affiliates as necessary to resolve any inquiries, claims or other issues that may be raised by a Governmental Authority in connection with such Tax Liabilities.
