NOW, THEREFORE, in consideration of the mutual terms, conditions and other agreements set forth herein and intending to be legally bound hereby, the parties agree as follows:

(b) Purchase Price. In consideration for the transfer of the Sale Shares, and upon the terms and subject to the conditions of this Agreement, at the Closing, Purchaser shall pay, or cause to be paid, to each Seller an amount in cash equal to the amount set forth opposite that Seller’s name on Schedule 1.1 hereto (the “Purchase Price”), which represents a purchase price of $2.25 per Ordinary Share.

Section 1.6 Withholding Taxes. Each Seller shall be liable for any withholding or similar taxes imposed on the purchase of the Sale Shares owned by such Seller (“Withholding Taxes”) and shall indemnify Purchaser for any tax liability (and any related interest, penalties, losses, costs and expenses and the costs and expenses of defending Purchaser in any related tax investigation or proceeding (including costs and expenses of counsels and tax advisors)) imposed on Purchaser as a result of Purchaser’s failure to withhold or deduct Withholding Taxes from the Purchase Price at the Closing. Each Seller shall promptly provide to Purchaser any information reasonably requested by Purchaser in order to comply with Tax reporting requirements of Purchaser in connection with the acquisition of the Sale Shares.

ARTICLE II

REPRESENTATIONS AND WARRANTIES

Section 2.1 Representations and Warranties of Sellers. Each Seller, severally and not jointly, hereby represents and warrants to Purchaser as of the date hereof and as of the Closing Date that:

(a) Due Organization and Power. Such Seller is duly organized, validly existing and in good standing under the law of its jurisdiction of organization. Such Seller (A) has all requisite power and authority to own its properties and assets and to carry on its business as it is now being conducted and (B) is in good standing and is duly qualified to transact business in each jurisdiction in which it is required to be so qualified, except, in the case of clause (A) or (B), where the failure to have such power and authority or to be in good standing would not reasonably be expected to prevent, materially delay or materially impede the ability of such Seller to consummate the transactions contemplated by this Agreement.

(b) Authority; Execution and Delivery; Enforceability. Such Seller has the requisite power and authority to execute and deliver this Agreement and the Representation Letter and to perform its obligations hereunder and thereunder. The execution and delivery by such Seller of this Agreement and the Representation Letter and the performance by such Seller of its obligations hereunder and thereunder have been duly authorized by all necessary action on the part of such Seller. Each of this Agreement and the Representation Letter has been duly executed and delivered by such Seller and, assuming due authorization, execution and delivery by the other parties hereto, constitutes a legal, valid and binding agreement of such Seller, enforceable against such Seller in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) applicable to such Seller.

(c) Title to Shares. The number of Sale Shares being sold by such Seller is set forth opposite its name on Schedule 1.1 hereto. Such Seller has good and valid title to the Sale Shares that it owns, free and clear of any and all Encumbrances. The Sale Shares owned by such Seller were duly authorized and validly issued, are fully paid and non-assessable, were issued in compliance with applicable Law and were not issued in violation of, or subject to, any preemptive, subscription or other similar rights of any other person. Upon the transfer of the Sale Shares owned by such Seller to Purchaser on the Closing Date in accordance with this Agreement, Purchaser will receive good and valid title to such Sale Shares, free and clear of any and all Encumbrances, other than those arising from the act, omission or condition of Purchaser or its Affiliates.

(d) No Approvals. The execution, delivery and performance by such Seller of this Agreement and the consummation by such Seller of the transactions contemplated hereby will not require any consent or approval of, or filing with or notice to, any Governmental Authority under any provision of Law applicable to such Seller.

Section 2.2 Representations and Warranties of Purchaser. Purchaser hereby represents and warrants to Sellers as of the date hereof and as of the Closing Date that:

(a) Due Organization and Power. Purchaser is duly organized, validly existing and in good standing under the law of the Cayman Islands. Purchaser (A) has all requisite corporate power and authority to own its properties and assets and to carry on its business as it is now being conducted and (B) is in good standing and is duly qualified to transact business in each jurisdiction in which it is required to be so qualified, except, in the case of clause (A) or (B), where the failure to have such power and authority or to be in good standing would not reasonably be expected to prevent, materially delay or materially impede the ability of Purchaser to consummate the transactions contemplated by this Agreement.

(b) Authorization and Validity of Agreement. Purchaser has the requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The execution and delivery by Purchaser of this Agreement and the performance by Purchaser of its obligations hereunder have been duly authorized by all necessary corporate action on the part of Purchaser. This Agreement has been duly executed and delivered by Purchaser and, assuming due authorization, execution and delivery by the other parties hereto, constitutes a legal, valid and binding agreement of Purchaser, enforceable against Purchaser in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) applicable to Purchaser.

(c) No Approvals. The execution, delivery and performance by Purchaser of this Agreement and the consummation by Purchaser of the transactions contemplated hereby will not require any consent or approval of, or filing with or notice to, any Governmental Authority under any provision of Law applicable to Purchaser.

(d) Investment. Purchaser is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under U.S. Securities Act of 1933, as amended (the “Securities Act”). Purchaser is acquiring the Sale Shares for investment for its own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof.

(e) No Registration. Purchaser understands that the Sale Shares being sold by Sellers have not been and will not be registered under the Securities Act or with any State or other jurisdiction of the United States, are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act and may not be reoffered, resold, pledged or otherwise transferred except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. Purchaser understands that the availability of an exemption from registration provisions of the Securities Act with respect to Sellers’ sale of the Sale Shares to Purchaser hereunder depends upon, among other things, the bona fide nature of Purchaser’s investment intent and the accuracy of Purchaser’s representations as expressed.

(f) Access to Information. Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Sale Shares.

(g) Purchaser acknowledges that each Seller is an Affiliate of the Company and, in such capacity, may from time to time be in possession of certain information about the Company unknown to Purchaser (“Other Company Information”). To the fullest extent permitted by law, Purchaser hereby waives any and all claims, actions, proceedings, suits, judgments, liens and executions, relating to such Other Company Information and further agrees not to sue such Seller or any of its trustees, beneficiaries, agents, controlling persons, advisors or affiliates for any loss, damage or liability relating to such Other Company Information.

Section 2.3 No Other Representations and Warranties. Purchaser acknowledges and agrees that, except as expressly provided in this Agreement and the Representation Letter, Sellers make no representation or warranty of any kind whatsoever, oral or written, express or implied, with respect to the Sellers, this Agreement, or the transactions contemplated hereby. Each Seller acknowledges and agrees that, except as expressly provided in this Agreement and the Representation Letter, Purchaser makes no representation or warranty of any kind whatsoever, oral or written, express or implied, with respect to Purchaser, this Agreement or the transactions contemplated hereby.
