                       CONTINUATION PAGES TO SCHEDULE 13D

     In order to avoid any question as to whether the Reporting Persons'
beneficial ownership is being reported on the proper form and in order to
provide greater investment flexibility, the Reporting Persons have decided to
file their beneficial ownership reports on the more detailed Schedule 13D rather
than on the short-form Schedule 13G and thereby to provide more expansive
disclosure than may be necessary. This Schedule 13D shall not be deemed an
admission that the Reporting Persons are required to file their beneficial
ownership reports on Schedule 13D rather than on Schedule 13G.

27, 2005, the Company entered into a Share Sale and Purchase Agreement (the
"Share Sale and Purchase Agreement") with Tdsoft and certain of Tdsoft's
shareholders, including HIPEP III Fund. Pursuant to the Share Sale and Purchase
Agreement, Tdsoft's shareholders agreed to sell and the Company agreed to
purchase all of the issued and outstanding share capital of Tdsoft by issuing to
Tdsoft's shareholders ordinary shares of the Company in


                                  Page 8 of 11



an aggregate amount equal to 75% of the issued and outstanding share capital of
the Company immediately following the transaction. As a result of the
transactions contemplated by the Share Sale and Purchase Agreement
(collectively, the "Transaction"), Tdsoft would become a wholly-owned subsidiary
of the Company.

          The Transaction closed on November 24, 2005. At that time, HIPEP III
Fund received 11,835,777 Ordinary Shares, par value New Israeli Shekel 0.01, of
the Company, in exchange for its entire interest in Tdsoft.

          Descriptions of the Share Sale and Purchase Agreement contained in
this Schedule 13D are qualified in their entirety by reference to the form of
such agreement, the full text of which is filed as Exhibit 1 hereto and
incorporated herein by reference.

          On November 25, 2005, the Company announced a 1-for-13 reverse split
of its Ordinary Shares, effective immediately before trading on Monday, November
28, 2005. After giving effect to this reverse stock split, HIPEP III Fund holds
910,444 shares of the Company's Stock.

investment considerations HIPEP III Fund deems material, HIPEP III Fund may from
time to time acquire or dispose of the Company's Stock in open market or
privately negotiated transactions.

          Except as described herein, the Reporting Persons have no present
plans or proposals that relate to or would result in any of the actions
