                                 SELLING HOLDERS

                  The debentures were originally issued by Comverse and sold by
Lehman Brothers Inc. in transactions exempt from the registration requirements
of the Securities Act of 1933, as amended, to persons reasonably believed by
Lehman Brothers to be "qualified institutional buyers" (as defined in Rule 144A
under the Securities Act). The selling holders (which term includes their
transferees, pledgees, donees or their successors) may from time to time offer
and sell pursuant to the prospectus and this prospectus supplement any or all of
the debentures and the shares of common stock issuable upon conversion of the
debentures.

                  Set forth below is certain information with respect to the
selling holders and the principal amount of debentures and the number of shares
of common stock beneficially owned by each selling holder. Such information has
been provided by the selling holders. Except as otherwise disclosed herein, none
of the selling holders has, or within the past three years has had, any
position, office or other material relationship with the company or any of its
predecessors or affiliates. Because the selling holders may offer all or some
portion of the debentures or the common stock issuable upon conversion thereof
pursuant to this prospectus supplement and the accompanying prospectus, no
estimate can be given as to the amount of the debentures or the common stock
issuable upon conversion thereof that will be held by the selling holders upon
termination of any such sales. In addition, the selling holders may have sold or
otherwise transferred, in transactions exempt from the registration requirements
of the Securities Act, all or a portion of the securities reflected in the
following table as being owned by them since the date on which they provided the
information regarding such ownership. Finally, additional selling holders may
from time to time be identified and, to the extent required under the Securities
Act, information with respect to such additional selling holders will be
provided in a further supplement to the prospectus.
