ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

                 On January 9, 1996, the registrant, Standard Microsystems
Corporation ("SMC"), together with SMC Enterprise Networks, Inc., a Delaware
corporation and wholly-owned subsidiary of SMC (collectively, the "Sellers"),
and Cabletron Systems, Inc., a Delaware corporation ("Cabletron") and Cabletron
Systems Acquisition, Inc., a Delaware corporation ("Acquisition"), entered into
an Asset Purchase Agreement (the "Agreement"). Under the terms of the Agreement,
on January 12, 1996, Cabletron and Acquisition (collectively, the "Buyer")
purchased substantially all of the assets (and assumed certain of the
liabilities) of the Enterprise Networks business unit of the Sellers for
$75,900,000 in cash. The Enterprise Networks business unit of Sellers designed,
developed, manufactured and sold enterprise-wide switching products for computer
networks. The purchase price is subject to adjustment based on certain changes
that may be required upon audit of the final assets acquired and liabilities
assumed by the Buyer at the closing date of the asset sale. The purchase price
was determined by arms-length negotiations between Sellers and the Buyer. Under
the terms of the Agreement, the Sellers have agreed to indemnify the Buyer
against certain losses. As security for Sellers' indemnification obligations,
$7,050,000 of the purchase price was placed in escrow to be used as a source
from which certain indemnifiable losses may be paid by Sellers to Buyer.

    NOTES TO UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS


UNAUDITED PRO FORMA CONSOLIDATED CONDENSED BALANCE SHEET

(A)      Reflects the sale of substantially all of the assets of the ENBU to
         Cabletron Systems, Inc. for $75.9 million in cash, of which $7.1
         million was placed in escrow pursuant to the Asset Purchase Agreement
         as security for the Company's indemnification obligations.

(B)      Represents certain assets not conveyed ($254,000) and liabilities not
         assumed ($1,434,000) by Cabletron, as well as an accrual for
         approximately $4.3 million of expenses directly related to the
         transaction.

(C)      Income taxes on the gain realized by the Company on the transaction
         have been accrued at a rate of 40%, which includes the statutory 
         federal tax rate and state tax rates of those states impacted by this
         transaction. Of the resulting $20.6 million accrued for income taxes,
         $17.8 million is estimated to be currently payable, and $2.8 million is
         deferred.

(D)      An after-tax gain of approximately $31.0 million on this transaction is
         presented within these assumptions.

UNAUDITED PRO FORMA CONSOLIDATED CONDENSED STATEMENTS OF INCOME

(A)      Represents various allocated selling, general and administrative
         expenses which would not have been eliminated had the transaction
         occurred as presented. These expenses include general marketing
         services, sales administration and certain field sales expenses.

(B)      Income taxes have been provided at a rate of 39%, which approximates
         the effective combined federal and state statutory rate for the periods
         presented.

(C)      The Company reported a $944,000 extraordinary loss (net of tax) on an
         early extinguishment of debt in fiscal 1995. This loss is excluded from
         these pro forma results for the year ended February 28, 1995.
