     To The Holders of Ordinary Shares, Warrants to Purchase Ordinary Shares and
Options to Purchase Ordinary Shares, of Wiztec Solutions Ltd.:

     Convergys Corporation and Convergys Israel Investments Ltd., as a result of
previous privately negotiated purchases of Shares and its recently completed
tender offer, own approximately 68.2% of the Ordinary Shares, New Israeli Shekel
1 Par Value (the "Shares"), of Wiztec Solutions Ltd. Since the holders of at
least 90% of the Shares did not accept the recently completed tender offer of
Convergys Corporation and Convergys Israel Investments Ltd., as previously set
forth in the Offer to Purchase, Convergys Israel Investments Ltd. is electing to
engage, from time to time, in its sole discretion, in open market and privately
negotiated purchases of Shares and warrants to purchase Shares, at prices which
may be greater or less than the $18.30 per Share price previously offered. In
connection with these transactions, Convergys Corporation and Convergys Israel
Investments Ltd. are required and hereby update the materials previously sent to
you by enclosing their Schedule 13E-3, Amendment No. 4.

SPECIAL FACTORS. Security holders are directed to the "Special Factors" section
of the previously distributed Offer to Purchase materials, as such section has
been supplemented by Items 7, 8 and 9 of the enclosed Schedule 13E-3, Amendment
No. 4.
