Unless otherwise defined herein, capitalized terms are used herein as defined in the BCA.

In order to (i) induce the Company, Holdco and EverArc to enter into the BCA and to proceed with the consummation of the transactions contemplated by the BCA, (ii) induce Holdco to issue to you equity incentives pursuant to the equity incentive plan to be adopted by Holdco pursuant to Section 8.03(b) of the BCA and (iii) protect and preserve the legitimate business interests of EverArc, Holdco and the Company and the goodwill to be developed by the Company in its business, the Restricted Party hereby agrees with EverArc, Holdco and the Company as follows:

Commencing on the Closing Date and ending on the three (3) year anniversary of the Closing Date (the “Restricted Period”), the Restricted Party shall not, and shall cause each of his affiliates not to, anywhere in the Restricted Territory, directly or indirectly, engage in any Competitive Activities. The Restricted Territory shall mean anywhere in the world where the Company (directly or through any Company Subsidiary) conducts its Business (as defined below) as of the Closing Date.    The Restricted Party acknowledges that the Company conducted its Business throughout the Restricted Territory and the Restricted Party provided services to the Company throughout the Territory. The Restricted Party shall be deemed to be engaged in Competitive Activities if such Restricted Party or any of his affiliates (i) serves as a shareholder, owner, officer, director, member, manager, trustee or partner of, or consults with, advises or assists in any way, whether or not for consideration, any corporation, partnership, firm, proprietorship or other business organization that engages in any Competitive Activity (a “Competitor”) or (ii) endorses the services of any such Competitor, solicits customers, provides or otherwise serves as an intermediary for any such Competitor or loans money or renders any other form of financial assistance to any such Competitor.

The parties undertake to carry out any award of the tribunal without delay, and waive their right to refer any question of law and any right of appeal on the law or merits to a court of law or other judicial authority, insofar as such waiver may be validly made. The parties agree that an arbitral tribunal appointed under this Letter Agreement may exercise jurisdiction with respect to both this Letter Agreement and any of the exhibits or schedules hereto (except as otherwise expressly provided therein), and that any disputes involving more than one of such agreements, exhibits or schedules shall proceed as a consolidated arbitration in accordance with Article 10 of the ICC Rules.
