ITEM 3.  IDENTITY AND BACKGROUND

        Item 3(b) is hereby amended and supplemented by adding thereto the 
following:

Executive Severance Amendments

        On August 8, 1997, the Company and Purchaser entered into letter
agreements with all of the executive officers of the Company (excluding Mr.
Larkin) concerning the operation and interpretation of the officers' existing
Severance Agreements with the Company after the Merger. Pursuant to the letter
agreements with Laureen DeBuono and Michael Downey, the existing Severance
Agreements between the Company and those two executive officers will be amended,
as of the Effective Time of the Merger, to provide that in the event either
executive terminates employment for any reason at any time after the
consummation of the Merger and within twenty-four months of the completion of
the Offer, such termination shall be deemed to be for "Good Reason," as defined
in the Severance Agreement and the executive will be entitled to all benefits
arising under the Severance Agreement upon a termination for Good Reason
following a Change in Control (as defined in the Severance Agreement). Pursuant
to the letter agreements with each of Boudewijn Bollen, David Illingworth,
Kenneth Summer, David Swedlow and Russell Hays, the existing Severance
Agreements between the Company and those executive officers will be amended, as
of the Effective Time of the Merger, to provide that (1) if the executive
remains employed until December 31, 1997, in the event the executive terminates
his employment for any reason thereafter through June 30, 1998, such termination
shall be deemed for "Good Reason" and the executive will be entitled to all
benefits arising under



                                       1

 
the Severance Agreement upon a termination for Good Reason following a Change in
Control, (2) if the executive remains employed on July 1, 1998, he will be
entitled to receive a payment equal in amount to the severance pay provided in
the Severance Agreement upon a termination for Good Reason, and his existing
Severance Agreement will be terminated as of that date, and (3) the executive
officers will not be entitled to terminate employment under the Severance
Agreement for "Good Reason" prior to December 31, 1997 solely because of a
change in status, title, position or responsibilities that do not constitute a
significant adverse change in the executive's responsibilities. The Company and
Purchaser have also agreed with each of Messrs. Bollen, Illingworth, Sumner,
Swedlow and Hays that upon termination of employment by the Company without
cause during the period from July 1, 1998 through June 30, 2000 (the
"Continuation Period"), the executive will be entitled to a continuation of his
then-existing life insurance, disability, medical, dental and hospitalization
benefits during the Continuation Period and outplacement and career counseling
services.
