The Registrant hereby withdraws from registration a total of 11,478
shares of its common stock, $.01 par value, registered pursuant to its
Registration Statement on Form S-8 (registration number 333-39817), effective
November 7, 1997 (the "Registration Statement"). The Registration Statement was
filed with respect to shares of the Registrant's common stock purchasable upon
options outstanding under the Coral Systems, Inc. Amended and Restated Stock
Option Plan (including its predecessor plan, the Coral Systems, Inc. Stock
Option Plan) that the Registrant assumed in connection with its acquisition of
Coral Systems, Inc. At the time of filing of the Registration Statement, the
ratio at which shares of common stock of Coral Systems, Inc. were converted into
shares of common stock of the Registrant remained subject to certain post-
closing adjustments and therefore could not be definitively determined. The
conversion ratio has since been determined and is less than the conversion ratio
assumed for purposes of filing the Registration Statement. This Post-Effective
Amendment No. 1 to the Registration Statement is being filed to reduce the
number of shares registered to the total number actually issuable, based on the
final conversion ratio, upon the exercise of all of the options outstanding
under the Coral Systems, Inc. Amended and Restated Stock Option Plan.
