ITEM 2.        ACQUISITION OR DISPOSITION OF ASSETS

        On May 18, 1998, Giga-tronics Incorporated, a California corporation
(the "Registrant"), acquired Microsource, Inc., a California corporation
("Microsource"), by merging Giga Micro Corp., a wholly-owned subsidiary of the
Registrant, with and into Microsource, with Microsource as the surviving
corporation. The purchase price (the "Purchase Price") consisted of $1,500,000
plus contingent payments based upon future net income of Microsource during the
two fiscal years after the effective time of the merger. By virtue of the
merger, Microsource became a direct, wholly-owned subsidiary of the Registrant,
and all of Microsource's outstanding capital stock prior to the merger was
converted into rights to receive a pro rata portion of the Purchase Price.
Additionally, all outstanding options and warrants to purchase shares of
Microsource common stock which were not exercised prior to closing were
cancelled.

        Prior to the merger, James Cole served as a member of the Board of
Directors of both the Registrant and Microsource. In addition, immediately prior
to the merger, the Registrants owned 3,985,069 shares, equalling approximately
12%, of the outstanding Common Stock of Microsource.
