Item 2.  Acquisition or Disposition of Assets

         (a)  On August 15, 2001, as originally reported in a Current Report on
Form 8-K filed by the Registrant on August 16, 2001, the Registrant's wholly-
owned subsidiary and Compensated Devices, Inc. consummated a purchase and sale
of assets. Micro CDI Acquisition Corp., a wholly-owned subsidiary of the
Registrant, plans to operate the acquired business or assets at the same four
physical locations in Melrose, Massachusetts where the seller had operated them
prior to August 15, 2001. Prior to August 15, 2001, affiliates of the
shareholders of Compensated Devices, Inc. had leased to Compensated Devices,
Inc. the four principal premises where it conducted business operations. Those
leases were terminated as part of this transaction, and Micro CDI Acquisition
Corp. has entered into new leases with those same affiliated entities. For these
assets the Registrant's subsidiary has paid approximately $7.7 million in cash
to the seller, approximately $3.9 million in the form of the Registrant's one-
year promissory note, approximately $1.4 million was paid in the form of
repayment of loans made by a bank, and the balance consisted of assumption of
specified obligations in the amount, aggregately, of approximately $1.0 million.
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 CDI Acquisition Corp.'s
acquisition consisted of contributing or loaning some cash on hand. Compensated
Devices, Inc. and its shareholders previously had no material relationship with
the Registrant, its directors or officers, or their respective associates.

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

Item 5.  Other Matters

              On August 2, 2001, as originally reported in a Current Report on
Form 8-K filed by the Registrant 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.

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