ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

      (a) On January 13, 1998, TriQuint Semiconductor, Inc., a Delaware 
corporation ("TriQuint" or the "Company") acquired substantially all of the 
assets of the Monolithic Microwave Integrated Circuit ("MMIC") operations of 
the former Texas Instruments' Defense Systems & Electronics Group from 
Raytheon TI Systems, Inc., a Delaware corporation ("RTIS") and a wholly owned 
subsidiary of the Raytheon Company ("Raytheon"). The MMIC operations include 
the Gallium Arsenide ("GaAs") foundry and MMIC business of the R/F Microwave 
Business Unit that RTIS acquired on July 11, 1997 from Texas Instruments 
Incorporated, a Delaware corporation ("TI") which MMIC business includes 
without limitation, TI's GaAs Operations Group, TI's Microwave GaAs Products 
Business Unit, the MMIC component of TI's Microwave GaAs Products Business 
Unit, the MMIC component of TI's Microwave Integrated Circuits Center of 
Excellence and the MMIC research and development component of TI's Systems 
Component Research Laboratory (collectively, the "MMIC Business").

      Pursuant to a Final Judgment entered on November 6, 1997 (the "FINAL 
JUDGMENT") in the United States District Court for the District of Columbia 
in Civil Case No. 97-1515 known as UNITED STATES OF AMERICA V. RAYTHEON 
COMPANY AND TEXAS INSTRUMENTS, INC., a related Stipulation and Order entered 
in the same case on July 2, 1997, and a related Hold Separate and Partition 
Plan Stipulation and Order entered in the same case on July 2, 1997 (the 
"HOLD SEPARATE ORDER"), Raytheon agreed to promptly divest the MMIC Business 
and, pending such divestiture, to maintain the MMIC Business as an 
independent competitor held separate from Raytheon.

      Pursuant to and in accordance with the Final Judgment, an Asset 
Purchase Agreement (the "Agreement") was entered into, dated as of January 8, 
1998, by and between the Company and RTIS. The Company has assigned its 
rights under the Agreement to a wholly owned subsidiary, TriQuint 
Semiconductor Texas, Inc., a Delaware corporation, which will operate the 
MMIC Business, located primarily in Dallas, Texas.

      Under the terms of the Agreement, TriQuint acquired the MMIC Business 
for approximately $19.5 million in cash and 844,613 shares of TriQuint Common 
Stock (the "Shares") valued at approximately $19,500,000 for total purchase 
consideration of approximately $39 million. The Shares are redeemable at 
TriQuint's option at any time within 360 days of January 13, 1998 at a price 
of approximately $23 per share. The cash portion of the purchase price was 
financed through an equipment leasing arrangement through General Electric 
Capital Corporation involving certain assets acquired pursuant to the 
Agreement. The terms of the Agreement were the result of arm's-length 
negotiations between the parties.

      In connection with its approval of the transaction, the Department of 
Justice required that RTIS place all the Shares into a voting trust in order 
to divest itself of voting power with respect to the Shares. Accordingly, on 
January 13, 1998, RTIS entered into a Voting Trust Agreement with State 
Street Bank and Trust Company, a Massachusetts trust company ("State 
Street"), under which, for any matter for which any vote or consent is 
requested from holders of TriQuint Common Stock, 


                                      -2-


State Street will vote the Shares as nearly as practicable in the same 
proportion as the other holders of TriQuint Common Stock.

      (b) The MMIC Business designs, develops, produces and sells advanced 
high power and low noise GaAs MMIC products. The MMIC Business has an 
established GaAs operation capable of developing, designing and producing 
advanced GaAs MMICs used in defense and commercial applications. In the area 
of defense applications, the MMIC Business supplies military contractors with 
MMIC products and services for applications such as high power amplifiers, 
low noise amplifiers, switches and attenuators for active array radar, 
missiles, electronic warfare systems and space communications systems. In 
commercial applications, the MMIC Business provides products and services for 
wireless and space-based communication. The Company intends to continue such 
business.
