During the period commencing as of the date hereof and until the earlier of (i) all of the Notes cease to remain outstanding and (ii) one year after the Purchasers cease to beneficially own, directly or indirectly, any securities of the Company (such period, the “Term”), Executive hereby agrees that Executive 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, employee, consultant, investor or similar position) that engages in or render services to a Competitive Business, or otherwise interfere with the business of the Company or Company Affiliates, including without limitation:

Notwithstanding the foregoing paragraphs of this Section 2.1:

(ii) Executive represents that the entities identified in Schedule II represent the pre-existing relationships disclosed by the Company pursuant 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 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;

(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

2.3 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.

2.4 Specific Enforcement. Upon a breach by Executive of Section 2.1 or 2.2, 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; Arbitrations. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF PEOPLE’S REPUBLIC OF CHINA. Any dispute, controversy or claim arising out of or in connection with this Agreement shall be settled through negotiation between the parties; if the parties fail to resolve such dispute within sixty (60) days after the date such negotiation was first requested in writing by either party, it shall be settled by arbitration in accordance with the Arbitration Rules of the Chinese International Economic and Trade Arbitration Commission (“CIETAC”). In the case of any conflict between the terms of this Agreement and the CIETAC Arbitration Rules, the terms of this Agreement shall prevail. The institution administering the arbitration shall be CIETAC Beijing Headquarters. The seat of arbitration shall be Beijing. The arbitral tribunal shall consist of three arbitrators, with one appointed by the Executive, one appointed by the Purchasers and a third neutral arbitrator to be appointed by the other two party-appointed arbitrators, who shall not be a citizen of the PRC and who shall act as the chairman of the tribunal. The parties agree to the appointment of arbitrators who are not on CIETAC’s Panel of Arbitrators. If either party fails to appoint an arbitrator within the time specified in the CIETAC Arbitration Rules, or if the two party-appointed arbitrators fail to jointly appoint the third neutral arbitrator within the time specified in the CIETAC Arbitration Rules, the Chairman of CIETAC shall make such an appointment. The arbitration shall be conducted on a confidential basis. All arbitration proceedings shall be held in the Chinese language (with an English translator available to any party who so requests). Any arbitration award made by the arbitration panel shall be final and binding on the parties and may be entered and enforced in any court of competent jurisdiction. The parties shall submit to the jurisdiction of any such court for purposes of the enforcement of any such award. Notwithstanding the foregoing agreement to arbitrate, the parties expressly reserve the right to seek provisional relief from any court of competent jurisdiction to preserve their respective rights pending arbitration.
