Item 2.  Acquisition or Disposition of Assets

         (a)  On August 2, 2001, the Registrant's wholly-owned subsidiary and
New England Semiconductor Corp. and a wholly-owned subsidiary thereof
consummated a purchase and sale of assets. Micro NES Acquisition Corp., a
wholly-owned subsidiary of the Registrant plans to operate the acquired business
or assets at the same physical location in Lawrence, Massachusetts where the
seller has operated them prior to August 2, 2001. The Registrant has paid
approximately $3.3 million cash to the seller, approximately $6 million was paid
with a one-year promissory note and the balance of approximately $5 million was
mostly paid in the form of cash or assumed loans and other obligations specified
in the agreement. The parties arrived at the price and terms on the basis of
negotiations which resulted in a letter of intent signed and announced by the
Registrant in early June, 2001. The Registrant's funding of Micro NES
Acquisition Corp.'s acquisition consisted of contributing or loaning some cash
on hand. The New England Semiconductor Corp. and its shareholders previously had
no material relationship with the Registrant, its directors or officers, or
their respective associates. Another subsidiary of the Registrant had been a
sublessor to New England Semiconductor Corp., and that sublease was terminated
as part of this transaction.

         (b)  The assets include semiconductor manufacturing and testing
equipment. The Registrant will continue to put this equipment to use in
manufacturing and testing semiconductors.
