Item 5. Other Events

On December 7, 1995, the registrant announced that it had acquired McDATA
Corporation, a leader in data center network switching solutions.

The transaction, accounted for as a pooling of interests, is valued at 
approximately $234 million, and includes the acquisition of approximately
$60 million in McDATA working capital. The registrant issued approximately 
13.6 million shares of common stock, based on an average closing price of 
$17.21 for the ten trading days prior to the completion of the acquisition.
This brought the number of the registrant's outstanding shares (fully diluted)
to approximately 248 million. The registrant announced its agreement to acquire 
McDATA on October 25, 1995. After regulatory review and approval by McDATA 
shareholders, the acquisition has been completed.

The acquisition of McDATA is expected to be accretive to the registrant's
earnings, adding approximately 8-10 cents per share for the current fiscal year,
which ends December 30, 1995. McDATA, which will operate as a wholly-owned 
subsidiary of the registrant, is based in Broomfield, Colorado, employs 150 
people and expects its 1995 revenues to exceed $150 million.

Previously a privately-held company, McDATA's flagship product is the ESCON
Director, a high-speed fiber-optic based network switch designed to connect 
computers and peripherals within data center environments. The ESCON Director
is marketed by IBM Corporation under an exclusive OEM agreement.
