Item 4. Purpose of Transaction.

On March 30, 2006, the Issuer announced that, subject to the satisfaction or waiver of certain specified conditions, it intends to make an offer (the “Offer”) to purchase all of the issued ordinary shares of MFS Technology Ltd (“MFS”) in a voluntary general offer under Singapore law. The shareholders of MFS will be offered the option to receive either 0.0145 shares of the Issuer’s Common Stock for each share of MFS or cash. Completion of the Offer, if made, is dependent upon, among other things, approval by the stockholders of the Issuer of the issuance of the shares of Common Stock to be issued in the transaction.

Stark (as defined below) acquired the Common Stock reported herein in part to potentially cast votes in respect of the Offer.

The foregoing amount of Common Stock and percentage ownership represent the combined indirect holdings of Michael A. Roth and Brian J. Stark. The Reporting Persons share the power to vote or direct the vote and dispose of or direct the disposition of the shares of Common Stock referred to in this Schedule.

As the Managing Members of Stark Offshore and Stark Asia Management, the Reporting Persons possess voting and dispositive power over all of the foregoing shares.
