ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On June 15, 1999, Lattice Semiconductor Corporation, a Delaware
corporation and the registrant herein, purchased all of the outstanding
capital stock, $.01 par value of Vantis Corporation, a Delaware corporation,
from Advanced Micro Devices, Inc., a Delaware corporation, for an aggregate
purchase price of $500,080,000.

     The acquisition was made pursuant a Stock Purchase Agreement entered
into between Lattice and Advanced Micro Devices on April 21, 1999. Following
the acquisition, Vantis is now a wholly owned subsidiary of Lattice.

     The purchase price for the shares of Vantis was determined by
arms'-length negotiation between Lattice and Advanced Micro Devices, and was
funded in part with cash reserves held by Lattice, and in part with the
proceeds of borrowings from ABN AMRO Bank, N.V., as administrative agent for
a syndicate of banks. The ABN AMRO credit facilities consist of a $60 million
three-year revolving credit facility, and a $220 million three-year term
loan. Aggregate borrowings from the credit facilities for the acquisition
were approximately $253,000,000 as of June 15, 1999.

     For a more complete description of the terms of the acquisition of
Vantis please refer to the Stock Purchase Agreement, which is incorporated by
reference as Exhibit 2.1, to our Current Report on Form 8-K, dated April 21,
1999.

     (a) and (b) It is impracticable at this time for the Registrant to file,
together with this Current Report, the required financial statements and pro
forma financial information with respect to Vantis. Accordingly, the
