During the period commencing as of the date hereof and for so long as the later of (i) any of the Notes remain outstanding and (ii) any Warrants remain outstanding (such period, the “Term”), Executive hereby agrees that Executive (including his spouse, infant children, siblings, any company or undertaking in which he holds a controlling interest, or any person related by marriage or consanguinity) will not, directly or indirectly, engage in, or have any interest in, any person, firm, corporation, or business (whether as an executive, officer, director, agent, security holder, consultant, investor or similar position) that engages in a Competitive Business, or otherwise interfere with the business of the Company or Company Affiliates, including without limitation:

2

(a) either on his own behalf or on behalf of any other person, solicit business similar to the Business from any customer, supplier, distributor of, or a person in a similar commercial relationship with, the Company or Company Affiliates; and

(b) either on his own behalf or on behalf of any other person, solicit, employ or otherwise engage as an employee, independent contractor, or otherwise any person who is and was, at any time during one year prior to such solicitation, employment or engagement, an employee of the Company or Company Affiliates, or in any manner induce any employee of the Company or Company Affiliates to terminate his or her employment therewith.

Notwithstanding the foregoing paragraphs of this Section 2.1:

(i) Executive may own, directly or indirectly, as an investor, securities of any corporation (the stock of which is publicly traded) engaging in a Competitive Business, so long as Executive’s aggregate holdings in each such corporation shall not constitute more than five percent (5%) of such corporation’s voting stock;

(ii) Executive represents that the entities identified in Schedule II represent the pre-existing relationships disclosed by the Company in the Disclosure Schedules to the Purchase Agreement which form part of the Transaction Documents and do not engage in a Competitive Business and for the foregoing reason, the Executive may continue his involvement as a shareholder, officer or director of such entities so long as such entities do not engage in a Competitive Business during such involvement; and

(iii) Executive may serve as a shareholder, director or officer of any entity that is not engaged in a Competitive Business.

2.2 Continued Employment. Executive agrees that during the Term, (a) except in the event of an involuntary termination, he will continue to serve as the President or a senior officer of the Company; and (b) he will not voluntarily resign as a director of the Company.

2.3 Confidentiality and Other Covenants. Executive agrees that:

(a) he shall keep confidential any information, including Trade Secrets, relating to the Company, Company Affiliates, and the Business (unless such disclosure is permitted in writing by the Company, required under law or by order of any governmental or regulatory authority, or relates to information already in the public domain, or to a third party who has rightfully obtained such Trade Secrets without breach of any confidentiality obligation);

(b) all Work Product of Executive conceived (whether solely or jointly with others) within the scope of his employment with the Company belongs to the Company and any and all of his rights to such Work Product, to the extent not yet assigned, are hereby assigned to the Company;

3

(c) upon the termination of his employment with the Company, at the request of the Company, he shall return to the Company all of the Company’s proprietary items in his possession or under his control and shall not retain any copies or other physical embodiment of any of such items; and

(d) upon the termination of his employment with the Company, he shall not hold himself out as an employee, agent or representative of the Company.

2.4 Termination. The parties agree that the Term shall terminate, and this Agreement shall be deemed terminated and of no further effect, without necessity of further action by Executive or the Purchasers, upon the expiration of the Term.

2.5 Specific Enforcement. Upon a breach by Executive of Section 2.1 or 2.3, in addition to such damages as the Purchasers can show they have sustained, directly or indirectly, by reason of said breach and in addition to any other remedies to which Purchasers may be entitled under the laws of the PRC, the Purchasers shall be entitled to injunctive relief against Executive if such relief is applicable and available, as monetary compensation alone would be inadequate and insufficient. Nothing in this Agreement shall be construed as limiting the Purchasers’ remedies in any way.

Section 3. Miscellaneous.

3.1 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, in each case, to the extent permitted by applicable law, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable, to the extent permitted by applicable law.

3.2 Counterparts. This may be executed in counterparts, each of which shall be deemed to be an original, and all such counterparts together shall constitute but one and the same instrument.

3.3 Governing Law; Arbitration. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF PEOPLE’S REPUBLIC OF CHINA.
