Items 2.01 - Completion of Acquisition or Disposition of Assets

On April 28,  2006,  Standard  Microsystems  Corporation  (SMSC)  completed  and
submitted to certain  former  shareholders  of OASIS  SiliconSystems  Holding AG
(OASIS) its calculation of the contingent  consideration due to them pursuant to
the Share  Purchase  Agreement  dated as of March 30, 2005 (the "Share  Purchase
Agreement")  by and among the  shareholders  of OASIS,  SMSC, and SMSC GmbH (now
known as SMSC Europe GmbH), a wholly owned  subsidiary of SMSC. On or before May
12, 2006, SMSC or SMSC Europe GmbH will pay approximately  $12.4 million in cash
and 162,422 shares in SMSC common stock to certain former  shareholders of OASIS
as  additional  consideration  for the  acquisition  of OASIS.  Such  additional
consideration  was  contingent  upon  satisfaction  of certain  post-acquisition
performance goals by the former OASIS business as described in Article IV of the
Share Purchase Agreement. The source of the cash used for these payments will be
existing balances. SMSC's calculations are final and binding on the former OASIS
shareholders  unless  challenged in accord with Article IV of the Share Purchase
Agreement  within  three (3) months  from  April 28,  2006.  The Share  Purchase
Agreement  is Exhibit  2.1 to SMSC's  Form 8-K filed on April 5,  2005,  and the
acquisition was completed on March 30, 2005. There are no material relationships
between  SMSC and the  former  OASIS  shareholders  other than in respect of the
transaction,  and that many of them have  remained as  employees  of SMSC or its
subsidiaries.


Item 3.02 - Unregistered Sale of Equity Securities

SMSC  will  issue  162,422  unregistered  shares of its  common  stock to former
shareholders  of OASIS as the  contingent  consideration  described in Item 2.01
above. These shares will be issued in reliance on an exemption from registration
under Section 4 (2) of the Securities Act of 1933.
