3.2 No Conflict. The execution and delivery by Seller and Seller Affiliate of this Agreement, and the performance by Seller and Seller Affiliate of their obligations hereunder, as of the date hereof do not and as of the Closing Date will not (i) violate or contravene any provision of applicable Law or Order, (ii) violate or contravene the certificate of incorporation or by-laws of the Company, or (iii) violate or contravene, or require any consent or other action by any person or entity under, constitute a default under, any agreement, contract or note binding upon Seller or Seller Affiliate, except for those notices, consents and waivers which have been obtained prior to the date hereof.

3.3 Ownership of Shares. The Shares have been duly authorized and validly issued and are fully paid and non-assessable. Seller is and on the Closing Date will be the record and beneficial owner of the Shares, free and clear of all security interests, claims (pending or threatened), liens, pledges, charges, equities or other encumbrances, limitations or restrictions (including any restriction on the right to vote, sell or otherwise dispose of such Shares) (“Encumbrances”). Seller has the legal right and power, and all authorization and approval required by law, to enter into this Agreement and to sell, transfer and deliver the Shares free and clear of all Encumbrances and to the best knowledge of Seller and Seller Affiliate, none of such legal right and power and authorization and approval has been restricted by the HK Lawsuit (as defined below).

-3 -

3.4 Delivery of Shares. Delivery of the stock certificates for the Shares, duly endorsed or accompanied by stock powers duly endorsed in blank, against payment therefor by Purchaser pursuant to this Agreement at the Closing, will pass valid title to such Shares to Purchaser, free and clear of all Encumbrances.

3.5 No Approvals. No filing with, or consent, approval, authorization, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign, is necessary or required for the execution and delivery of this Agreement, the performance by Seller and Seller Affiliate of their obligations hereunder or in connection with the sale and delivery of the Shares hereunder or the consummation of the transactions contemplated by this Agreement except for the approval of the board of directors of the Company required under the Rights Agreement (as referred to in Section 6.2(d) below).

3.6 Seller’s Remaining Shares. There are 4,592,624 shares of the Company’s Common Stock registered under the name of Seller as of the date of this Agreement. After the Closing, there will be 1,479,704 shares of the Company’s Common Stock registered under the name of Seller (the “Remaining Shares”). That certain pending lawsuit in the High Court of the Hong Kong Special Administrative Region, Court of First Instance against Seller, Seller Affiliate and certain other co-defendants (Action No. 1424 of 2012, the “HK Lawsuit”) is the only adverse claim and outstanding dispute in respect of the Remaining Shares’ ownership that Seller and Seller Affiliate are aware of.

3.7 Seller’s Status. Seller is a sophisticated investor with sufficient investment or financial knowledge and experience as well as knowledge in the Company, which enable her to properly evaluate the risks and merits of her participation in the transaction contemplated hereunder and protect her own interest in connection therewith. Seller has made a determination based on her own independent review and such professional advice as she deems appropriate that (i) her consideration of the sale of the Shares to Purchaser in the transaction contemplated hereunder is fully consistent with her financial needs, objectives and condition, and (ii) the terms of the transaction contemplated hereunder have been agreed through arm’s-length negotiation and are fair to Seller.

3.8 Purchase Price. Seller fully understands that the Purchase Price may be less than the current trading price of the Shares and believes that, due to the size of Seller’s holdings, any attempt to dispose of the Shares on the public market would most likely drive the market price down and result in an average price per share that is less than an amount equaling (x) the Purchase Price divided by (y) the number of Shares.

3.9 Information. Seller acknowledges that (i) Seller and Seller Affiliate have received and reviewed the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, and the Company’s Current Reports on Form 8-K filed with the SEC after December 31, 2012, and the other filings made by the Company with the SEC, (ii) Seller and Seller Affiliate had the opportunity to ask questions of and receive answers from the Company directly about the expected financial results for the quarter ended March 31, 2013 and other non-public matters, (iii) Seller was a director of the Company between July 19, 2006 and December 17, 2010, (iv) Xx. Xx Xxxxx Xxxx, representative of Seller and Seller Affiliate, was a director of the Company between December 17, 2010 and July 20, 2012 and had access to material non-public information relating to the Company, and (v) Seller and Seller Affiliate are familiar with the Company’s business and financial conditions. Seller further acknowledges that Purchaser has informed Seller that Purchaser may be viewed as an “insider” (as defined under relevant rules promulgated under the US Securities Laws) with respect to the Company and may have material non-public information regarding the Company (“MNPI”). Such MNPI, when it is eventually available and disclosed publicly, may cause the market price of the Company’s common stock to increase or decrease substantially. Seller understands, based on her experience, the disadvantage to which Seller is subject due to the disparity of information between Purchaser and Seller. Notwithstanding this, Seller desires to engage in the transaction contemplated hereunder. Seller hereby waives any future claim that Seller might have based on the failure by Purchaser to disclose the MNPI and expressly releases Purchaser from any and all liabilities arising from Purchaser’s failure to disclose such MNPI, and Seller agrees to make no claim against Purchaser in respect of the transaction contemplated under this Agreement related to Purchaser’s failure to disclose such MNPI to Seller, except with respect to representations, warranties, covenants and agreements expressly made by Purchaser in this Agreement. Based on such information and investigation as Seller has deemed appropriate and without reliance upon any MNPI that Purchaser may have, Seller has independently made her own analysis and decision to enter into the transaction contemplated hereunder. Except for the representations, warranties and agreements of Purchaser expressly set forth in this Agreement, Seller is relying exclusively on her own sources of information, investment analysis and due diligence (including such professional advice as she deems appropriate) with respect to the transaction contemplated hereunder.

3.10 Foreign Corrupt Practices Act. Any proceeds received by Seller under this Agreement will be received by Seller as principal and not as agent for others, and no part of any payment hereunder will be paid or assigned to or shared with any third party except for the payment of lawful costs and expenses. Neither Seller nor Seller Affiliate is an officer or employee of, or acting in an official capacity for, any Government Entity (as defined below), any political party or official thereof, or any candidate for political office (individually and collectively, a “Government Official”). Neither Seller nor Seller Affiliate is holding or using any Shares on behalf of any Government Official or Government Entity. “Government Entity” as used in this Section 3.10 means any government or any department, agency or instrumentality thereof, including any entity or enterprise owned or controlled by a government or a public international organization.

3.11 No Purchaser Obligations. Seller and Seller Affiliate hereby acknowledge and agree that (a) Purchaser is not and shall not be construed as a fiduciary for Seller or Seller Affiliate in connection with the transaction contemplated hereunder; (b) except as set forth in this Agreement, Purchaser has not made and will not make any representation or warranty, whether express or implied, of any kind or character and has not provided any advice or recommendation in connection with the transaction contemplated hereunder; (c) Purchaser will have no responsibility with respect to any representations, warranties or agreements made by any other person or entity; and (d) Purchaser shall have no liability or obligation (i) with respect to the accuracy or completeness, as of any date, of any information provided to, or any omission to provide information to, Seller by any third party other than Purchaser, its affiliates and its representatives, or (ii) with respect to any valuation or other materials that may have been provided or made available to Seller in connection with the transaction contemplated hereunder that were prepared by a third party other than Purchaser, its affiliates and its representatives.
