the public in Israel of units consisting of convertible debentures, warrants for
shares and options for convertible debentures.

A total of 78,000 units are being offered at a minimum price per unit of NIS

immediate gross proceeds of approximately $31 million from the offering. Of the
units offered, 80% have been initially allocated to institutional investors who
have made firm bid commitments and the balance will be offered to the public in
Israel. The underwriters have committed to purchase the balance to the extent
not purchased by the public. The offering is expected to be completed on or
about June 29, 2006; however, there is no assurance that the offering will be
completed. The listing for trading on the Tel-Aviv Stock Exchange of the
securities included in the units and the underlying shares has been approved by
the Israeli Securities Authority and by the Tel Aviv Stock Exchange.

Each unit consists of (i) convertible debentures in the face amount of NIS 2,100

NIS 100 principal amount of convertible debentures at an exercise price equal to
