Item 2.  Acquisition or Disposition of Assets

Acquisition of BKC Semiconductors
- ---------------------------------

(a)  On May 15, 1998, Microsemi Corporation, a Delaware corporation (the
"Registrant"), issued a news release which announced that the Registrant's
wholly-owned subsidiary, Micro BKC Acquisition Corp. ("Merger Sub"), merged
with and into BKC Semiconductors Incorporated, a Massachusetts corporation
("BKC") effective May 15, 1998.  The Registrant's news release concerning the
merger is attached as Exhibit 99.1 hereto and incorporated herein by this
reference.

     The merger resulted the Registrant owning all of the outstanding capital
stock of BKC in exchange for approximately $13.2 million in cash and all of
the outstanding options to purchase BKC stock being cancelled in exchange for
an additional $0.5 million in cash, approximately.  The shareholders of BKC
approved the merger at a special meeting of the BKC shareholders held on
May 14, 1998.  BKC was the surviving corporation in the merger.  Microsemi
financed the acquisition with drawings on its line of credit from Imperial
Bank.

     The merger was consummated pursuant to an Agreement and Plan of Merger
dated as of January 21, 1998 ("Merger Agreement") among the Registrant, Merger
Sub and BKC.  The Merger Agreement is attached as Exhibit 2.1 hereto and
incorporated herein by this reference.

  As BKC does not constitute a significant business under Regulation S-X, the
financial statements and pro forma financial information regarding BKC are
not required to be provided.

(b)  The Registrant intends to continue to operate BKC as a stand-alone
subsidiary, operating its property, plant and equipment in Lawrence,
Massachusetts.
