Exhibits A and B attached hereto and incorporated herein by
reference.  The Exhibit A equipment will be delivered FOB Raytheon
Semiconductor's Mountain View facility whose address is set forth
above ("the Delivery Point") beginning on the Closing Date
(specified in paragraph 3.3 hereinbelow).  The Exhibit B equipment
will be delivered at the Delivery Point (after Raytheon
Semiconductor has fulfilled its Customer Order Backlog) on or
before March 31, 1995 as to the assembly equipment; on or before
May 31, 1995 as to the test equipment; and on or before June 30,
1995 as to the remaining equipment.
