ITEM 5.    OTHER EVENTS.
- ------     ------------

         On April 17, 2002, we acquired ISP FineTech Ltd., or FineTech, and some
related  intangible assets from ISP Hungary Holdings Limited and ISP Investments
Inc. for $32 million,  under a purchase  agreement that we entered into with ISP
Hungary Holdings Limited,  ISP Investments Inc. and ISP Chemco Inc. (we refer to
these  three  companies  collectively  as the ISP  Group,  and we  refer to such
purchase  agreement  as  the  Agreement).  FineTech,  based  in  Haifa,  Israel,
specializes  in the design and  manufacture of  proprietary  synthetic  chemical
processes  used  in  the  production  of  complex  organic   compounds  for  the
pharmaceutical  industry.  FineTech  will be  operated  by us as a  wholly-owned
subsidiary  and will  provide  immediate  chemical  synthesis  capabilities  and
strategic opportunities to us and our customers.

         Under the terms of the Agreement, we acquired from ISP Hungary Holdings
Limited  all  of  the  capital  stock  of  FineTech  and we  acquired  from  ISP
Investments  Inc. some  intangible  assets relating to FineTech's  business.  In
determining the purchase  price,  we principally  considered (i) the anticipated
synergies between our existing businesses,  including employees,  and the assets
and business being acquired,  including intellectual property,  (ii) comparative
businesses  of  FineTech  and the  estimated  cost and time  required to start a
comparable  business  and (iii)  the  historical  and  projected  cash  flows of
FineTech's  business.  The acquisition  was financed by cash-on-hand  and is not
expected to have a material effect on earnings in 2002 and will be accounted for
using the purchase method. We expect the depreciation and amortization resulting
from the transaction goodwill and the write-up of the assets purchased to be tax
deductible.

         Dr. Arie Gutman,  who was the founder and  president of FineTech,  will
become the chief executive officer of FineTech. We have entered into a five-year
employment  arrangement with Dr. Gutman with non-competition  provisions,  stock
option grants and a negotiated salary. Additionally, we have selected Dr. Gutman
to our Board of Directors.

         We are  planning  to  transfer a portion of  FineTech's  personnel  and
technological  resources to a  laboratory  facility in the  northeastern  United
States.  A parallel  research  program has been  established in Rhode Island and
will immediately be staffed with FineTech employees.

         The above description is a summary of principal terms of the Agreement.
We have  attached  a  complete  copy of the  Agreement  to this  Form  8-K as an
exhibit.  Our  description  of the  terms and  conditions  of the  Agreement  is
qualified in its entirety by reference to such exhibit.
