Subject: Supplement to Offer to Cancel and Reissue Stock Options

-------------------------------------------------------------------------------

On May 22, 2002 we sent you an email regarding our offer to cancel and reissue
certain of your outstanding stock options. As required by U.S. securities laws,
all documents associated with this program were filed with the Securities and
Exchange Commission (SEC). As is often the case with such filings, the SEC has
exercised its right to review the documents and has requested certain
modifications be made to the Offer to Exchange document. Although in our view
the modifications do not materially change the terms of the stock exchange
program, we are required to provide you with an updated version this document.
Additionally, the SEC has requested that we provide you with current Comverse
Technology, Inc. financial information.

In response to the above, we are now notifying you of the following updates and
supplements to the documents previously provided to you, all of which are
available at our website at http://www.comverse.com/StockExchangeProgram/.
Specifically, you should pay particular attention to the following links on this
website:

         o        Offer to Exchange - This document has been updated to
                  incorporate the modifications requested by the SEC. The
                  sections that have been amended are Section 7 ("Conditions Of
                  The Offer"), Section 17 ("Additional Information") and Section
                  18 ("Forward Looking Statements; Miscellaneous").

         o        Annual Report on Form 10-K - This is a copy of our Annual
                  Report filed with the SEC for the fiscal year ended January
                  31, 2002.

         o        Quarterly Report on Form 10-Q - This is a copy of our
                  Quarterly Report filed with the SEC for the first quarter of
                  our 2002 fiscal year, which ended April 30, 2002.
