This Amendment No. 6 amends item 5 of this Statement on Schedule 13D, as previously filed with the Securities and Exchange Commission. Unless otherwise defined in this Amendment No. 6 to Schedule 13D, capitalized terms have the meanings given them in the Schedule 13D previously filed.

Item 5. Interest in Securities of the Issuer

The Issuer has advised the Reporting Persons that there were 25,025,436 Ordinary Shares outstanding on December 31, 2002. The percentages of Ordinary Shares outstanding set forth in this Statement are based on 25,172,287 Ordinary

Shares consisting of the 25,025,436 outstanding Ordinary Shares and 146,851 Ordinary Shares issuable upon exercise of the convertible subordinated notes held by Clal Electronics Industries Ltd.("Clal Electronics").

The following table sets forth the sales of Ordinary Shares made by Clal Electronics from September 24, 2002 (the day after the last transaction reported in Schedule 13D) through February 13, 2002. All such sales were made in the open market transactions on the Tel Aviv Stock Exchange:

Date of    Transaction	Number of Ordinary  Shares Sold	Price Per Ordinary Share
September 30, 2002	5,000	$ 0.160
October 7, 2002	5,000	$ 0.135
December 13, 2002	25,000	$ 0.145
February 6, 2003	110,000	$ 0.180
February 7, 2003	50,000	$ 0.180
February 12, 2003	50,000	$ 0.170

Except as disclosed above, none of the Reporting Persons purchased or sold any Ordinary Shares of the Issuer since September 24, 2002.

As of February 13, 2003, IDB Holding Corporation Ltd., IDB Development Corporation Ltd., Clal Industries and Investments Ltd., Clal Electronics and the Reporting Persons who are natural persons may be deemed to share the power to vote and dispose of the 1,189,001 Ordinary Shares held directly by Clal Electronics (consisting of 1,042,150 Ordinary Shares directly held by it and an additional 146,851 Ordinary Shares which Clal Electronics may purchase pursuant to its conversion of its convertible subordinated notes of Orckit Communications Ltd.), constituting approximately 4.72% of the Ordinary Shares.

Page 10 of 11 pages

Since the Reporting Persons own less than 5% of the Ordinary Shares of the Issuer, this Amendment No. 6 is the last amendment to this Statement on Schedule 13D.

Signature

After reasonable inquiry and to the best of knowledge and belief of the undersigned, the undersigned hereby certify that the information set forth in this Statement is true, complete and correct.
