The Company confirms that neither it nor any other Person acting on its behalf has provided Purchaser or its agents or counsel with any information that constitutes or might constitute material, nonpublic information. The Company understands and confirms that Purchaser will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided to Purchaser regarding the Company, its business and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf of the Company with respect to the representations and warranties made herein are true and correct with respect to such representations and warranties and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. The Company acknowledges and agrees that Purchaser has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 2 hereof.

(a) Transfer Restrictions. The Purchaser acknowledges that (i) neither the Common Stock, Warrants nor the Common Stock issuable in exercise of the Warrants have been registered under the Securities Act, and such securities may not be transferred unless (A) subsequently registered thereunder or (B) they are transferred pursuant to an exemption from such registration, and (ii) any sale of the Common Stock, the Warrants or the Common Stock issuable, exercise or exchange thereof (collectively, the “Securities”) made in reliance upon Rule 144 under the Securities Act (“Rule 144”) may be made only in accordance with the terms of said Rule 144. The Purchaser understands that, although Rule 144 is not exclusive, the Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such

13

persons and the brokers who participate in the transactions do so at their own risk. The provisions of Section 4(a) and 4(b) hereof, together with the rights of the Purchaser under this Agreement and the other Primary Documents, shall be binding upon any assignee of the Purchaser as well as any subsequent transferee of the Common Stock and the Warrants.

(b) Restrictive Legend. The Purchaser acknowledges and agrees that, until such time as the Securities shall have been registered under the Securities Act or the Purchaser demonstrates to the reasonable satisfaction of the Company and its counsel that such registration shall no longer be required, such Securities may be subject to a stop-transfer order placed against the transfer of such Securities, and such Securities shall bear a restrictive legend in substantially the following form:

THESE SECURITIES (INCLUDING ANY UNDERLYING SECURITIES) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL OR OTHER EVIDENCE REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION SHALL NO LONGER BE REQUIRED.

(c) Filings. The Company undertakes and agrees that it will make all required filings in connection with the sale of the Securities to the Purchaser as required by federal and state laws and regulations, or by any domestic securities exchange or trading market, and if applicable, the filing of a notice on Form D (at such time and in such manner as required by the rules and regulations of the Commission), and to provide copies thereof to the Purchaser promptly after such filing or filings. With a view to making available to the holders of the Securities the benefits of Rule 144 and any other rule or regulation of the Commission that may at any time permit such holder to sell securities of the Company to the public without registration or pursuant to a Registration Statement, the Company shall (a) at all times make and keep public information available, as those terms are understood and defined in Rule 144, (b) file on a timely basis with the Commission all information that the Commission may require under either of Section 13 or Section 15(d) of the Exchange Act and, so long as it is required to file such information, take all actions that may be required as a condition to the availability of Rule 144 (or any successor exemptive rule hereafter in effect) with respect to the Common Stock; and (c) furnish to any holder of the Securities forthwith upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144, (ii) a copy of the most recent annual or quarterly report of the Company as filed with the Commission, and (iii) any other reports and documents that a holder of the Securities may reasonably request in order to avail itself of any rule or regulation of the Commission allowing such holder to sell any such Securities without registration.

(d) Reservation of Common Stock. The Company will at all times have authorized and reserved for the purpose of issuance a sufficient number of shares of Common Stock to provide for the issuance of Common Stock the exercise of the Warrants (the “Conversion Shares”).

14

(e) Return of Warrants on Exercise. Upon any partial exercise by the Purchaser or its assignees of the Warrants, the Company shall issue and deliver to the Purchaser or applicable assignee, within seven business days of the date on which the Warrants is exercised, new Warrants representing the number of adjusted shares of Common Stock covered thereby, in accordance with the terms thereof.

(f) Replacement Certificates and Warrants.

(i) The certificate(s) representing the shares of the Common Stock held by the Purchaser shall be exchangeable, at the option of the Purchaser at any time and from time to time at the office of Company, for certificates with different denominations representing, as applicable, an equal aggregate number of shares of the Common Stock as requested by the Purchaser upon surrendering the same. No service charge will be made for such registration or transfer or exchange.

(ii) The Warrants will be exchangeable, at the option of the Purchaser or its assignees, at any time and from time to time at the office of the Company, for other Warrants of different denominations entitling the holder thereof to purchase in the aggregate the same number of shares of Common Stock as are purchasable under such Warrants. No service charge will be made for such transfer or exchange.

(g) Publicity. The Company and Purchaser shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby. Notwithstanding the foregoing, the Company shall not publicly disclose the name of Purchaser, or include the name of Purchaser in any filing with the Commission or any regulatory agency or principal trading market, without the prior written consent of Purchaser, except to the extent such disclosure is required by law or market regulations, in which case the Company shall provide Purchaser with prior notice of such disclosure.

(h) Loans. It is contemplated that Ligent US and Hisense OE may borrow funds on commercially reasonable terms from Hisense Group or other third parties for the sole purpose of funding the operations of Ligent US, the STB Division and Hisense OE, in an aggregate amount not to exceed US $9,000,000 (the “Hisense Loans”). The Company and Purchaser agree that the Hisense Loans shall be repaid from the Funds.

(a) Placement Fee. On the Execution Date, the Company shall (i) pay $870,000 to SGC (the “Placement Fee”) and (ii) issue an aggregate of 138,385 five-year Warrants, in the form attached hereto as Exhibit A, exercisable at $4.93 per share to SGC, provided that such Warrants may be subsequently assigned by SGC pursuant to a schedule to be provided by SGC on or before the Final Closing Date.

(b) Use of Funds. The Company shall instruct Carlton Fields to make the following disbursements of the Funds from its trust account for the following purposes: (1) payment of the Placement Fee, (2) legal, audit and other expenses associated with the consummation of the transactions contemplated by the Transaction Documents as incurred directly by the Company (not its shareholders) and (3) after the Final Closing Date, repayment of the Hisense Loans.
