The Management Agreement shall be subject to the approval of the Company’s Shareholders Meeting.

11.3.        Board of Directors.  The Company will use commercially reasonable efforts to appoint the Preferred Directors at the Shareholders Meeting, so that following the First Closing the Lead Investor’s nominees shall have been appointed to fill a majority of the Board, regardless of the number of members composing the Board.

It is agreed that a loss of a customer or potential customer, partner or potential partner shall be considered in the ordinary course of business and shall not constitute an Adverse Event. It is agreed that “Adverse Event” shall also include circumstances that prevent the Company from holding the Shareholders Meeting for approval of this Agreement on or before the date set for the First Closing.

considering the Company’s size, potential exposure and other relevant factors, and in any event in an amount not exceeding US$5,000,000. The Policy will apply to obligations and liabilities of the Company’s directors and officers who serve in office in the Company and/or in the Subsidiaries, before the date of the First Closing for any wrongful act, omission, or event that preceded such date, all this being subject to the conditions of the Policy and its exclusions.

12.4.        Services Fee.  Recognizing the time, effort and resources dedicated by the Lead Investor (since the execution of Term Sheet entered into between the parties on January 12, 2006), in the provision to Company of consultation and assistance in devising a strategy for enhancing its operations, if the Shareholders Meeting does not approve the Equity Investment, then the Company shall pay the Lead Investor for such services a fee of US$250,000.

12.5.        Right of First Refusal on Investments.  In addition to the break-up fee set forth in Section 12.4 above, if within twelve (12) months following the rejection of the Shareholders’ Meeting of the Equity Investment, the Company accepts another investment proposal (the “Alternative Investment”), the Company shall promptly advise the Lead Investor of such Alternative Investment and the Lead Investor shall have a right of first refusal to make the Alternative Investment on the terms thereof, by giving written notice to the Company within twenty-one (21) days of its receipt of the Company’s notice that an offer for an Alternative Investment has been made to the Company. Failure of the Lead Investor to respond in writing to a notice from the Company with respect to an Alternative Investment within the time-frame stated above shall be deemed a waiver by the Lead Investor of this right of first refusal.

12.9.        New Indemnification Agreements.  No later than the First Closing, the Company shall have entered into new indemnification agreements with those of its officers and Directors who were parties to the Terminated Agreements and those of its officers and Directors holding office following the First Closing, providing for indemnification by the Company in an aggregate amount of US$1,500,000 for all indemnifiable events and for all indemnified persons (the “New Indemnification Agreements”). The terms and conditions for indemnification shall be set forth in the New Indemnification Agreements, which shall include, among other matters, a provision requiring the indemnified person to comply with the requirements of the insurance company underwriting the Policy (defined in Section 12.1 above) to the extent that the indemnifiable event is covered by the Policy. In the event that all necessary corporate approvals, as required by applicable law for the New Indemnification Agreements, are not obtained prior to the First Closing, then as soon as such approvals are obtained the Company will enter into the New Indemnification Agreements with those of its officers and Directors who were parties to the Terminated Agreements and those of its officers and Directors holding office following the First Closing. The Company’s Directors and officers as of the date of this Agreement and its officers and Directors holding office following the First Closing are third party beneficiaries of this covenant and are entitled to enforce such obligations.
