ITEM 3.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      As more fully described in Item 4 below, pursuant to the terms of the
Asset Purchase Agreement (as defined below), RTIS has acquired 844,613 shares
of TriQuint Common Stock as a portion of the purchase price paid by TriQuint to
RTIS for substantially all the assets of the MMIC Business (as defined below).

ITEM 4.    PURPOSE OF TRANSACTION.

      On July 11, 1997, RTIS, a wholly-owned subsidiary of Raytheon Company, a
Delaware corporation ("Raytheon"), purchased the Gallium Arsenide ("GaAs")
foundry and Monolithic Microwave Integrated Circuit ("MMIC") business of the
R/F Microwave Business Unit of Texas Instruments Incorporated, a Delaware
corporation ("TI"), including, without limitation, TI's GaAs Operations Group,
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, RTIS and TriQuint
entered into an Asset Purchase Agreement, dated as of January 8, 1998 (referred
to herein as the "Purchase Agreement," a copy of which is attached hereto as
Exhibit 1), pursuant to which RTIS sold and TriQuint purchased substantially
all the assets of the MMIC Business.

     Upon the closing of the transactions contemplated by the Purchase
Agreement on January 13, 1998 and pursuant to the terms of the Purchase 
Agreement, TriQuint issued 844,613 shares of TriQuint Common Stock (the
"Shares") as partial consideration for the MMIC Business. In connection with
the Final Judgment, 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, RTIS entered into a Voting Trust Agreement
with State Street Bank and Trust Company, a Massachusetts trust company ("State
Street"), on January 13, 1998 (the "Voting Trust Agreement," a copy of which is
attached hereto as Exhibit 2) with respect to the Shares, which TriQuint issued
in the name of "State Street Bank and Trust Company, as Trustee" and delivered
to State Street to be held pursuant to the terms of the Voting Trust Agreement.




      Pursuant to the Voting Trust Agreement, State Street has sole voting
power with respect to the Shares. With respect to any matter for which any vote
or consent is requested from holders of TriQuint Common Stock, State Street
will, pursuant to the terms of the Voting Trust Agreement, vote the Shares as
nearly as practicable in the same proportion as the other holders of TriQuint
Common Stock with respect to such matter. RTIS has retained sole dispositive
power with respect to the Shares; RTIS has sole authority to direct State
Street to sell, assign or transfer the Shares, subject to the provisions of the
Voting Trust Agreement and TriQuint's rights to repurchase the Shares described
in Item 6 below.

     Except as set forth in the Purchase Agreement and the Voting Trust
Agreement, neither RTIS nor, to the best of RTIS' knowledge, any of the
individuals named in Schedule I hereto, has any plans or proposals which relate
to or which would result in any of the actions specified in clauses (a) through
(j) of Item 4 of Schedule 13D.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER

     (a)-(b) By reason of its execution of the Voting Trust Agreement, pursuant
to Rule 13d-3(a)(2) promulgated under the Act, RTIS may be deemed to have sole
dispositive power with respect to the Shares subject to the Voting Trust
Agreement and, accordingly, may be deemed to beneficially own 844,613 Shares of
TriQuint Common Stock, or approximately 9.0% of the TriQuint Common Stock
outstanding on January 13, 1998.

     Except as set forth above, neither RTIS nor, to the best of RTIS'
knowledge, any of the individuals named in Schedule I hereto, owns any TriQuint
Common Stock.

     (c) Neither RTIS nor, to the best of RTIS' knowledge, any of the
individuals named in Schedule I hereto, has effected any transaction in the
TriQuint Common Stock during the past 60 days.

     (d) None.

     (e) Inapplicable.




ITEM 6.    CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
RESPECT TO SECURITIES OF THE ISSUER

     Pursuant to the Purchase Agreement, for a period of 180 days after January
13, 1998, TriQuint may, at its option, repurchase from RTIS and RTIS will, at
the request of TriQuint, sell to TriQuint all of the Shares at a purchase price
equal to $19,500,000, subject to adjustment in certain events. By written
notice to RTIS received not later than the 180th day after January 13, 1998,
TriQuint may extend such period for an additional 180 days after such 180th day
after January 13, 1998. TriQuint's call rights described above lapse if not
exercised within the specified time periods.

     Except as provided in the Purchase Agreement and the Voting Trust 
Agreement or as set forth herein, neither RTIS nor, to the best of RTIS'
knowledge, any of the individuals named in Schedule I hereto, has any 
contracts, arrangements, understandings or relationships (legal or otherwise)
with any person with respect to any securities of TriQuint, including, but not
limited to, transfer or voting of any securities, finder's fees, joint 
ventures, loan or option arrangements, puts or calls, guarantees of profits,
division of profit or losses, or the giving or withholding of proxies.

                            ASSET PURCHASE AGREEMENT


     THIS ASSET PURCHASE AGREEMENT (this "Agreement") is dated as of the 8th
day of January, 1998, by and between RAYTHEON TI SYSTEMS, INC., a Delaware
corporation (the "Seller"), and TRIQUINT SEMICONDUCTOR, INC., a Delaware
corporation (the "Buyer").

     On July 11, 1997, the Seller, a wholly-owned subsidiary of Raytheon
Company, a Delaware corporation (the "Parent"), purchased the Gallium Arsenide
("GaAs") foundry and Monolithic Microwave Integrated Circuit ("MMIC") business
of the R/F Microwave Business Unit of Texas Instruments Incorporated, a
Delaware corporation ("TI"), including, without limitation, TI's GaAs
Operations Group, 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

pending such divestiture, to maintain the MMIC Business as an independent
competitor held separate from Parent; and

     The Seller desires to sell and the Buyer desires to purchase the MMIC
Business.

     In connection with the negotiation and preparation of this Agreement, the
Seller has prepared, and the Buyer has reviewed, a set of disclosure schedules,
dated the date hereof and delivered separately as one or more volumes (the
"Disclosure Schedule", with any reference in this Agreement to a Schedule being

      Seller's facilities at 13510 and 13588 North Central Expressway, Dallas,

           (d) any rights under the Asset Purchase Agreement dated as of

Further, without limiting the foregoing, with respect to any asset necessary to
and presently used in connection with the MMIC Business that is also used by
the Seller in connection with another business, excluding any assets to be
retained by the Seller and used to provide services pursuant to the Master
Services Agreement, the parties shall cooperate in good faith to (i) determine
which business predominantly uses such asset in order that such party is vested
with title thereof and (ii) coordinate the shared used thereof by both parties.
With respect to any contracts or licenses applicable to both the MMIC Business
and other businesses of the Seller, the Seller and the Buyer will cooperate to
structure contractual arrangements providing them both with the relevant rights
and obligations under such contract or license. These arrangements may take the
form of a subcontract or sublicense or causing the other party to such contract
or license to agree to split the contract or license into two separate
agreements.


                                   Article 2

to the MMIC Business of any nature, fixed or contingent, known or unknown,
including liabilities for product warranty claims and product returns and
including liabilities for outstanding orders for capital equipment listed on
Schedule 1.1(h) (collectively, the "Assumed Obligations"), excluding, however,

those liabilities for Taxes (as defined in Article 17) that remain the
responsibility of the Seller pursuant to Article 14, (iii) those liabilities of

Liabilities").


                                   Article 3

                                 Purchase Price

     3.1. Purchase Price. At the Closing, the Buyer shall deliver cash and
shares of the Buyer's Common Stock, $.001 par value (the "Shares"), to the
Seller, as the aggregate purchase price for the Acquired Assets, subject to
adjustment as provided in Section 3.2 hereof (the "Purchase Price"). The
Purchase Price shall be payable as follows: (i) $19,500,000 shall be paid in
cash or by wire transfer of same day funds (the "Cash Portion") and (ii) the
remainder of the Purchase Price shall be paid by delivery of Shares (the "Stock
Portion") having an aggregate value equal to $19,500,000, based on the average
of the closing bid prices of the Shares on the five trading days preceding the
Closing Date, as quoted through the NASDAQ National Market (the "Closing
Trading Price"); provided, however, that if the number of Shares that would
constitute the Stock Portion exceeds 9.9% of the number of Shares outstanding
as of the Closing Date after giving effect to the issuance of the Shares
constituting the Stock Portion, then (a) the Stock Portion shall consist of
9.9% of the number of Shares outstanding as of the Closing Date after giving
effect to the issuance of the Shares constituting the Stock Portion and (b) the
Cash Portion shall consist of (x) $39,000,000 less (y) the value, based on the
Closing Trading Price, of the Shares constituting the Stock Portion referred to
in clause (a). The Shares comprising the Stock Portion are entitled to the
rights, and subject to the limitations, set forth in the Registration Rights
Agreement (as defined in Section 6.12), as amended by the Amendment to
Registration Rights Agreement (as defined in Article 9) (as so amended, the
"Amended Registration Rights Agreement"), which shall include "demand" and
"piggyback" registration rights beginning 180 days after the Closing Date. The
Purchase Price shall be allocated among the Acquired Assets in the manner set
forth on Schedule 3.1 hereto. The Buyer and Seller shall report the purchase
and sale of the Acquired Assets, including, without limitation, in all federal,
foreign, state, local and other Tax Returns (as defined in Article 17) prepared
and filed by or for either of the Buyer or the Seller, in accordance with the
basis of allocation set forth on Schedule 3.1 hereto. The Buyer and the Seller
further agree that they will prepare and file asset acquisition statements on




Form 8594 reflecting such allocation with their Federal income tax returns for
the taxable year that includes the Closing Date.

      3.2. Purchase Price Adjustments.

           (a) Within sixty (60) days after the Closing Date, the Seller shall
      prepare and deliver to the Buyer an audited statement of the Acquired
      Assets and Assumed Obligations for the MMIC Business as of the close of
      business on the day immediately preceding the Closing Date (the "Closing
      Balance Sheet"). The Closing Balance Sheet shall be prepared in
      accordance with GAAP applied on a basis consistent with the October
      Balance Sheet (as defined in Section 5.5), except that the Closing
      Balance Sheet (i) will be prepared in accordance with the accounting
      procedures set forth on Schedule 3.2(a) hereto, (ii) will not include any
      cash or cash equivalents of the MMIC Business, (iii) will not have an
      accrual for Income Taxes payable by the Seller and (iv) will not contain
      any intercompany accounts.

           (b) When the Seller delivers the Closing Balance Sheet, the Seller
      shall also deliver a certificate (i) certifying that the Closing Balance
      Sheet was prepared in accordance with paragraph (a) above, and (ii)
      containing the Seller's calculations, based on the Closing Balance Sheet
      and calculated in a manner consistent with the Model Statement (as
      defined below) (the "Seller's Proposed Calculations"), of the Net Assets
      as of the Closing Date. As used in this Agreement "Net Assets" means the
      difference of (x) the book value of the total assets of the MMIC Business
      (including, without limitation, equipment, accounts receivable,
      inventory, prepaid expenses and deferred charges, but excluding cash and
      cash equivalents and intercompany accounts) constituting part of the
      Acquired Assets less (y) the book value of the total liabilities of the
      MMIC Business (including, without limitation accounts payable and accrued
      expenses, but excluding pension and accumulated post-retirement benefits,
      intercompany accounts and retained earnings) constituting part of the
      Assumed Obligations. Attached hereto as Schedule 3.2(b) is a preliminary
      statement of Net Assets as of October 31, 1997, based upon the balance
      sheet of the MMIC Business as of October 31, 1997 and the procedures for
      calculating Net Assets as provided above (the "Model Statement").

           (c) Within thirty (30) days after receipt of the Closing Balance
      Sheet and the accompanying certificate, the Buyer shall notify the Seller
      of its agreement or disagreement with the Closing Balance Sheet and the




      accuracy of any of the Seller's Proposed Calculations; provided, that the
      Buyer may only dispute the Closing Balance Sheet and the Seller's
      Proposed Calculations to the extent that they deviate from the
      requirements of paragraphs (a) and (b) above. If the Buyer disputes any
      such aspect of the Closing Balance Sheet or the amount of any of the
      Seller's Proposed Calculations, then the Buyer shall have the right to
      direct its independent accountants, at the Buyer's expense, to review and
      test the Closing Balance Sheet. The Buyer's accountants shall complete
      their review and test within thirty (30) days after the date the Buyer
      disputes the Seller's Proposed Calculations. If the Buyer and its
      independent accountants, after such review and test, still disagree with
      the Seller's Proposed Calculations, and the Seller does not accept the
      Buyer's proposed alternative calculations (the "Buyer's Proposed
      Calculations"), then, within thirty (30) days after the date of the
      Seller's rejection of the Buyer's Proposed Calculations, the Seller and
      the Buyer shall select a third nationally recognized independent
      accounting firm (the "Independent Accounting Firm") to resolve the
      remaining disputed items (the "Remaining Disputed Items") by conducting
      its own review and test of the Closing Balance Sheet and thereafter
      selecting either the Buyer's Proposed Calculation of the Remaining
      Disputed Items or the Seller's Proposed Calculation of the Remaining
      Disputed Items or an amount in between the two. The Independent
      Accounting Firm shall be instructed (i) that the scope of its review
      shall be limited solely to the Remaining Disputed Items, (ii) that it
      shall accept the Closing Balance Sheet and the Seller's Proposed
      Calculations except to the extent that they deviate from the requirements
      of paragraphs (a) and (b) above, and (iii) that it is to use every
      reasonable effort to complete such assignment and deliver copies of such
      opinion and, if required, a revised Closing Balance Sheet to the Buyer
      and the Seller within thirty (30) days following the date such Remaining
      Disputed Items are referred to it. The Buyer and the Seller agree that
      they shall be bound by the determination of the Remaining Disputed Items
      by the Independent Accounting Firm. The fees and expenses of the
      Independent Accounting Firm shall be paid jointly by the Buyer and the
      Seller.

           (d) Upon the determination pursuant to paragraph (c) of this Section
      3.2 of the definitive Closing Balance Sheet and the Net Assets as of the
      Closing Date, the Purchase Price shall be either (i) increased by the
      amount, if any, by which the amount of Net Assets is greater than
      $23,637,000 or (ii) decreased by the amount, if any, by which the amount
      of Net Assets is less than $23,437,000 (the "Adjustment"). If the
      Purchase Price is increased, the Buyer shall pay such amount to the




      Seller, and if the Purchase Price is decreased, the Seller shall pay such
      amount to the Buyer. Any such payment shall be made in cash or same day
      funds within ten (10) days after the determination of the Adjustment
      pursuant to paragraph (c). Any such payment shall bear interest at a rate
      equal to the "Prime Rate" as set forth from time to time in The Wall
      Street Journal "Money Rates" column from the Closing Date to the date
      preceding payment.

     3.3. Call Option on Shares. For a period of 180 days after the Closing
Date, the Buyer may, at its option, repurchase from the Seller, and the Seller
will at the request of the Buyer sell to the Buyer, all (but not less than all)
of the Shares constituting the Stock Portion at a purchase price equal to
$19,500,000 (or, in the event that the proviso to the second sentence of
Section 3.1 is applicable, such lesser amount corresponding to the value, based
on the Closing Trading Price, of the Shares constituting the Stock Portion)
(the "Call Price"). By written notice to the Seller received not later than the
180th day after the Closing Date, the Buyer may extend such period for an
additional 180 days after such 180th day after the Closing Date, provided that
the Buyer shall pay the Seller interest on a monthly basis at the daily rate
equivalent of 1% per month on the amount of the Call Price for the portion of
such additional 180 day period during which the Shares constituting the Stock
Portion have not been repurchased. The Buyer's call rights under this Section
3.3 shall be exercisable by the Buyer by written notice to the Seller
specifying the date and time of a closing for the repurchase (the "Call
Notice"), which shall be held at the offices of Bingham Dana LLP, 150 Federal
Street, Boston, Massachusetts, not earlier than five (5) days nor later than
ten (10) days after delivery of the Call Notice to the Seller. The receipt of a
Call Notice by the Seller shall constitute a binding agreement of the Buyer to
purchase the Shares constituting the Stock Portion from the Seller in
accordance with this Section 3.3. At the closing of the call option, the Buyer
shall pay the Seller the Call Price (plus any accrued but unpaid interest
thereon in accordance with this Section 3.3) in cash or by wire transfer of
same day funds, in exchange for the transfer of the Shares constituting the
Stock Portion from the Seller to the Buyer. The Buyer's call rights set forth
in this Section 3.3 shall lapse if not exercised within the time periods
specified above in accordance with the provisions hereof.

     3.4. Delay in Demand Registration. In the event that (i) the Seller, at
any time after the 180th day after the Closing, requests the Buyer in writing
to file a registration statement with respect to any of the Shares pursuant to
Section 2 of the Amended Registration Rights Agreement, (ii) the Buyer requests
that the filing of such registration statement be delayed for a period not in
excess of 180 days by delivery to the Seller of a certificate signed by the
Chairman of the Board of the Buyer pursuant to Section 2(d)(ii) of the Amended




Registration Rights Agreement stating that in the good faith judgment of the
Board of Directors it would be seriously detrimental to the Buyer and its
shareholders for such registration statement to be filed and that it is
therefore essential to defer the filing of such registration statement, and
(iii) the Buyer has not extended its call option under Section 3.3 for an
additional 180 days after the 180th day after the Closing Date and is therefore
not paying the Seller interest as contemplated by Section 3.3, the Buyer shall
pay the Seller interest on a monthly basis at the daily rate equivalent of 1%
per month on the amount of the Call Price for the period of such delay.


                                   Article 4

                                    Closing

           (a) The Seller shall duly execute and deliver to the Buyer or its
      nominee or nominees such bills of sale, certificates of title and other
      instruments of assignment or transfer with respect to the Acquired Assets
      as the Buyer may reasonably request and as may be necessary to vest in
      the Buyer all of the Seller's title to the Acquired Assets.

           (b) The Buyer shall deliver the Cash Portion of the Purchase Price
      by wire transfer to the Seller and the Stock Portion of the Purchase

      and deliver the Intellectual Property Agreement, the Master Services
      Agreement, the Supply Agreement, the Sublease Agreements, the Amendment
      to Registration Rights Agreement and the Non-Disclosure Agreement (as
      such terms are defined in Article 9 hereof and, collectively with this
      Agreement, the "Transaction Documents").


                                   Article 5

                    Representations And Warranties Of Seller

     The Seller represents and warrants to the Buyer as follows:

     5.1. Incorporation; Authority. The Seller is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware
and has all requisite corporate power and authority to carry on the MMIC
Business as now conducted.

     5.2. Rights to Sell Acquired Assets; Approvals; Binding Effect. The Seller
has all requisite corporate power and authority to enter into this Agreement
and the other Transaction Documents, to perform all of its agreements and
obligations hereunder and thereunder in accordance with their terms, and to
sell and transfer to the Buyer all of the Acquired Assets. This Agreement has
been duly executed and delivered by the Seller and constitutes, and the
Transaction Documents when executed and delivered by the Buyer will constitute,
the legal, valid and binding obligation of the Seller, enforceable against the
Seller in accordance with its terms, except as such validity, binding effect or
enforcement may be limited by bankruptcy, insolvency or similar laws affecting
creditors' rights generally or by equitable principles relating to the
availability of remedies.

     5.3. No Defaults. Except for consents to transfer with respect to any
agreement that is part of the Acquired Assets and except as set forth on
Schedule 5.3, and the consent referred to in Section 7.1 hereof, the entering
into of this Agreement and the other Transaction Documents, the performance and
compliance by the Seller with the terms hereof and thereof, and the
consummation of all the transactions contemplated hereby and thereby, will not
either currently, or after notice or lapse of time or both:





           (a) result in a violation of any provision of the charter, by-laws
       or other organizational documents of the Seller; or

           (b) result in a violation by the Seller of any statute, regulation,
      order, law, ordinance or restriction applicable to the Seller, other than
      any violation which would not have a Material Adverse Effect; or

           (c) result in a violation by the Seller of any judgment, order or
      decree of any court or judicial or quasi-judicial tribunal applicable to
      the Seller, other than any violation which would not have a Material
      Adverse Effect; or

           (d) violate or conflict with or result in a breach of, or constitute
      a default or acceleration of or give rise to a right of termination (or
      an event which with notice or lapse of time or both would become a
      default) under, any provision of any contract, indenture, mortgage,
      lease, agreement or other instrument primarily related to the MMIC
      Business to which the Seller is a party or to which the MMIC Business is
      subject, which would individually or in the aggregate have a Material
      Adverse Effect.

     5.4. Title to Assets. (a) The Seller owns or has the right to transfer all
of the Acquired Assets. At and as of the Closing, the Seller will convey to the
Buyer good and marketable title to the Acquired Assets, free and clear of all
Encumbrances (as defined in Article 17) except for Permitted Encumbrances (as
defined in Article 17); provided, however, that this paragraph (a) shall not be
considered a representation or warranty as to the non-infringement of any of
the intellectual property referred to in the Intellectual Property Agreement.

     (b) Except as set forth on Schedule 5.4, the Acquired Assets and the
Subleases, when utilized by a labor force substantially similar to that
utilized by the Seller for the MMIC Business as of the date of this Agreement,
and taken together with the services to be provided by the Seller pursuant to
the Master Services Agreement and the other assets to be made available to the
Buyer as provided in Section 1.3, are sufficient for the fulfillment by the
Buyer of its obligations under the Supply Agreement as they exist as of the
Closing Date and are adequate to conduct the MMIC Business after the Closing
Date in the same manner in all material respects as such business was conducted
immediately prior to the Closing Date. The preceding sentence shall not be
construed as a representation as to the adequacy or scope of the intellectual
property to be conveyed, licensed or sublicensed pursuant to the Intellectual



Property Agreement, with respect to which the Seller is making representations
and warranties as provided in Section 5.11.

     (c) The Acquired Assets constituting tangible personal property are in
good working condition, ordinary wear and tear excepted, have been properly
maintained in all material respects, are suitable in all material respects for
the purposes for which they are used, and conform in all material respects to
the requirements of all laws, ordinances and regulations applicable to their
use and ownership or lease by the Seller; and the buildings and structures
containing the space to be leased to the Buyer pursuant to the Subleases are
suitable in all material respects and properly zoned for the purpose for which
they are currently used, have been properly maintained in all material respects
to the extent the Seller is required to do so, and there are no material
outstanding work orders with respect to any maintenance, repair or alterations
to be performed by the Seller thereon.

     5.5. Financial Statements. The Seller has furnished to the Buyer, and
attached as Schedule 5.5 hereto are, copies of the unaudited balance sheet of
the MMIC Business as of October 31, 1997 (the "October Balance Sheet"), and the
unaudited income statement of the MMIC Business for the one month period then
ended (the "October Income Statement"). Each of such financial statements has
been prepared in accordance with the Seller's accounting policies and practices
except as otherwise noted on Schedule 5.5; and except as otherwise noted on
Schedule 5.5, the October Balance Sheet fairly presents in all material
respects the financial condition of the MMIC Business as of October 31, 1997,
with the exception that the October Balance Sheet excludes an allocation for
costs associated with certain services currently provided to the MMIC Business
by Seller and Raytheon Company.

     5.6. Absence of Certain Changes. Except as set forth on Schedule 5.6, from
October 31, 1997 to the date of this Agreement the MMIC Business has operated
only in the ordinary course and there has not been:

           (a) any change in the condition (financial or otherwise), results of
      operations, assets, liabilities or business of the MMIC Business other
      than changes arising in the ordinary course of business, none of which,
      individually or in the aggregate, has had a Material Adverse Effect (as
      defined in Article 17);

           (b) any acquisition or disposition by the Seller outside the
      ordinary course of business of any asset or property used primarily in




      the MMIC Business or necessary to and previously used in the MMIC
      Business;

           (c) any damage, destruction or casualty loss to any asset of the
      Seller and relating to the MMIC Business, whether or not covered by
      insurance, which has had a Material Adverse Effect;

           (d) any increase in (or commitment to increase) the compensation,
      pension or other benefits payable or to become payable to any of the
      officers, employees, agents or representatives of the MMIC Business or
      any bonus payments or arrangements made to or with any of them, that will
      constitute an Assumed Obligation, other than (i) increases amounting to
      less than $25,000 in the aggregate and effected on a basis consistent
      with the past practice of the Seller and (ii) any increase required under
      the terms of any of the benefit plans listed on Schedule 5.10(a) or (b)
      hereto;

           (e) any voluntary forgiveness or cancellation of any debt or claim
      of the MMIC Business in excess of $5,000 or any voluntary waiver of any
      right of material value other than compromises of accounts receivable in
      the ordinary course of business;

           (f) the imposition of any Encumbrance on any of the assets of the
      MMIC Business except for Permitted Encumbrances;

           (g) any disposition of or lapse of any intellectual property right
      or termination of any agreement under which the Seller (insofar as it
      relates to the MMIC Business) has any right or license, the disposition,
      lapse or termination of which would have a Material Adverse Effect;

           (h) any lapse, termination or expiration of any contract or
      agreement, including any joint venture agreement, teaming agreement,
      distribution agreement, supply agreement, license agreement, personal
      property lease or development contract, to which the Seller (insofar as
      it relates to the MMIC Business) had been a party, the lapse, termination
      or expiration of which would have a Material Adverse Effect; or

           (i) any intercompany transactions relating to the MMIC Business with
      any Affiliate (as defined in Article 17) of the Seller, except (i) in the
      ordinary course operation of the MMIC Business or (ii) involving
      consideration or transfers in any one transaction of not more than
      $25,000 and not more than $100,000 in the aggregate.





     5.7. Litigation, etc. As of the date of this Agreement, no proceeding,
arbitration, action or suit is pending or, to the knowledge of the Seller,
threatened against the Seller (insofar as it relates to the MMIC Business),
except as set forth on Schedule 5.7 hereto and except for any such proceeding,
arbitration, action, or suit that alleges claims, singly or in the aggregate,
in excess of $100,000. As of the date of this Agreement, the Seller (insofar as
it relates to the MMIC Business) has not received any written notice from any
Governmental Entity of any pending or threatened governmental investigation
relating to the MMIC Business which, if concluded with a determination adverse
to the MMIC Business, would have a Material Adverse Effect.

     5.8. Labor Relations. Except as set forth on Schedule 5.8, as of the date
of this Agreement there is no charge pending or, to the knowledge of the
Seller, threatened against the Seller alleging, with respect to any employee or
employees of the MMIC Business, any violation of any statute or regulation
relating to employment and employment practices, or any violation of any
collective bargaining agreement, any unlawful discrimination in employment
practices or any unfair labor practices before any court, agency, or other
judicial or arbitral body, except for any such violation that would not
individually or in the aggregate be in excess of $100,000. As of the date of
this Agreement, there is no labor strike, dispute, slow-down or work stoppage
actually pending or, to the Seller's knowledge, threatened against the Seller
(with respect to employees of the MMIC Business). No employees of the MMIC
Business are covered by any collective bargaining agreement, and no collective
bargaining agreement or other labor union agreement or agreement with organized
labor for employees of the MMIC Business is currently being negotiated or
pending negotiation. Except as set forth on Schedule 5.8 hereto, there has been
no material concerted work stoppage with respect to the MMIC Business during
the last three years.

     5.9. Contracts. Except for contracts, commitments, plans, agreements and
licenses listed on Schedules 1.1(g), 1.1(h), 5.9, 5.10(a) or 5.10(b), as of the
date of this Agreement, the Seller (insofar as it relates primarily to the MMIC
Business) is not a party to or otherwise bound by:

           (a) any contract or purchase order to sell products or provide
      services to any customer (i) providing for payments in excess of $100,000
      or (ii) having a term greater than one calendar year;

      compensation in excess of $100,000 or (ii) having a term greater than one
      calendar year;

           (c) any contract for the lease or sublease as lessee, lessor,
      sublessee or sublessor of real or personal property of the MMIC Business,
      or any license of computer software used primarily in the MMIC Business,
      requiring payments in excess of $25,000 per year;

           (d) except for purchase orders issued in the ordinary course of
      business, any contract requiring payments in excess of $25,000 for the
      purchase or sale of any personal property used primarily in the MMIC
      Business;

           (e) any contract or agreement containing non-competition covenants
      limiting the freedom of the Seller to operate the MMIC Business, or any
      exclusive licensing agreement with respect to any MMIC Business
      Intellectual Property;

           (f) any partnership, joint venture, teaming, consortium, or other
      similar contract, arrangement or agreement representing more than 5% of
      the MMIC Business' sales in 1996 or that the Seller reasonably believes
      as of the date of this Agreement will represent more than 5% of the MMIC
      Business' sales in 1997;

           (g) any development contracts relating primarily to the MMIC
      Business and requiring estimated or actual annual expenditures by Seller
      in 1997 in excess of $100,000; or

           (h) any contract or agreement for guaranty, indemnity or suretyship
      of Indebtedness of the MMIC Business in excess of $25,000.

     Neither the Seller nor, to the knowledge of the Seller, any other party to
any contract, agreement, lease or instrument listed on Schedules 1.1(g),
1.1(h), 5.9, 5.10(a) or 5.10(b) (collectively, the "Contracts") is, as of the
date of this Agreement, in default in complying with any provisions thereof,
except for any such default that would not have a Material Adverse Effect. All
Contracts are valid, legally binding and enforceable in accordance with their
respective terms in all material respects. As of the date of this Agreement,
there is no pending written claim or request, or to the Seller's knowledge, no
threatened claim or request, for equitable adjustment under any Government
Contract (as defined in Article 17) that would reasonably be expected to have a




Material Adverse Effect. As of the date of this Agreement, except where the
same would not, individually or in the aggregate, have a Material Adverse
Effect, the Seller has not (i) received any written notice of the intention of
any party to terminate any Contract, whether as a termination for convenience
or for default of the Seller thereunder, or (ii) received any written cure
notice or show cause notice (as defined in the Federal Acquisition Regulations
Part 49, P. 49.607(a) and (b), respectively) in respect of any Government
Contract. The MMIC Business is in compliance with all obligations relating to
any equipment or fixtures owned by any Governmental Entity and loaned, bailed
or otherwise furnished to or held by any part of the MMIC Business, except
where the failure to so comply would not, individually or in the aggregate,
have a Material Adverse Effect.

      5.10.  Pensions and Benefits.

           (a) Except as set forth on Schedule 5.10(a) hereto, as of the date
      of this Agreement, the Seller does not maintain or have any obligation to
      make contributions to, any employee benefit plan (an "ERISA Plan") within
      the meaning of Section 3(3) of the United States Employee Retirement
      Income Security Act of 1974, as amended ("ERISA"), or any other
      retirement, profit sharing, stock option, stock bonus or other benefit
      program (a "Non-ERISA Plan"), in either case, for the benefit of any
      officers, employees or consultants of the MMIC Business. The Seller has
      heretofore delivered or made available to the Buyer copies or summaries
      of each such ERISA Plan and Non-ERISA Plan and any associated funding
      instruments and, with respect to any such ERISA Plan, the most recently
      completed annual report (with any required attachments), the most recent
      IRS determination letter, and any other advisory opinions or rulings
      applicable to such Plan.

           (b) To the Seller's knowledge, except as set forth on Schedule
      5.10(b), all of Seller's ERISA Plans and Non-ERISA Plans have been
      maintained and operated in all material respects in accordance with all
      federal, state, provincial and local laws applicable to such plans, and
      the terms and conditions of the respective plan documents.

     5.11.  Intellectual Property. (a) Schedule 5.11 hereto sets forth a list of
the patents, pending patent applications, invention disclosures and mask works
that will be transferred to the Buyer at the Closing. Pursuant to the
Intellectual Property Agreement (as defined in Article 9 hereof), and subject
to the terms, conditions and restrictions set forth therein, the Buyer shall,
as of the Closing Date, have the right to use, hold for use or otherwise




exploit (to the extent set forth in the Intellectual Property Agreement) all
the MMIC Business Intellectual Property, whether or not set forth in Schedule
5.11, in a manner not materially different than that in which such MMIC
Business Intellectual Property is or may be used, held for use or otherwise
exploited by the Seller in the MMIC Business as of the date hereof and as of
the Closing Date. The Seller and the Buyer acknowledge that the foregoing
representation and warranty is not intended to act as a limitation on the use
by the Buyer of the MMIC Business Intellectual Property.

     (b) The Seller owns or has the right to use all material MMIC Business
Intellectual Property on the date hereof and as of the Closing Date. The MMIC
Business Intellectual Property is not subject to any material Encumbrances,
other than Permitted Encumbrances, and is not subject to any obligations
inconsistent with the terms of the Intellectual Property Agreement. The Seller
has used commercially reasonable measures to protect the secrecy,
confidentiality and value of the material MMIC Business Intellectual Property.
To the knowledge of the Seller, no material MMIC Business Intellectual Property
(other than unregistered copyrights) has been used, divulged or appropriated
for the benefit of any Person other than the Seller, except where such use,
divulgence or appropriation would not, individually or in the aggregate, have a
Material Adverse Effect.

     (c) As of the date hereof, Seller has not made any claim in writing of a
violation, infringement, misuse or misappropriation by others of rights of the
Seller to or in connection with any material MMIC Business Intellectual
Property.

     (d) As of the date hereof, there is no pending or to the knowledge of the
Seller, threatened claim by any third Person of a violation, infringement,

on the part of the Seller, is required in connection with the consummation of
any of the transactions contemplated hereby, except for any approval,

      with respect to the Environmental Permits except where the failure to
      have such Environmental Permits or where the violation, investigation or
      proceeding relating thereto would not, individually or in the aggregate,
      have a Material Adverse Effect.

         (iii)  Since December 31, 1994, no notice, notification, demand,
      request for information, citation, summons, complaint or order has been
      received by the Seller or, to the knowledge of the Seller, is pending or

      any material penalty been assessed against any part of the MMIC Business

Agreement the Seller has timely filed within the time period for filing or any
extension granted, or appropriately amended, with respect thereto all federal,




state, local and other returns, estimates and reports ("Returns") relating to
any and all Taxes or other governmental charges, obligations or fees including
any secondary or transferee liability for taxes and any related interest or

examined or audited by the IRS or any other taxing authority. As of the date of
this Agreement there are no pending or, to the Seller's knowledge, threatened
audits, examinations, assessments, asserted deficiencies or claims for
additional Taxes with respect to the Seller. There are (and as of the Closing
there will be) no Encumbrances, other than Permitted Encumbrances, relating to
or attributable to Taxes, which if adversely determined, would result in an
Encumbrance, other than a Permitted Encumbrance, on the Acquired Assets or
would otherwise have a Material Adverse Effect upon the MMIC Business.

      5.20 Absence of Undisclosed Liabilities.

     (i) As of October 31, 1997, the Seller did not have any liability or
obligation (absolute, accrued, contingent or otherwise) primarily related to
the MMIC Business of a nature required by GAAP to be reflected on the October
Income Statement or October Balance Sheet or disclosed in the notes thereto,
and from October 31, 1997 to the date of this Agreement the Seller has not
incurred any liability primarily related to the MMIC Business, in each case
except: (i) liabilities stated or adequately reserved against in the October
Balance Sheet; and (ii) liabilities incurred in the ordinary course of business
and which are not individually or in the aggregate material to the financial
condition or earnings of the Seller insofar as it relates to the MMIC Business
or the value of the Acquired Assets; and

     (ii) As of the date of this Agreement, the Seller has not been notified in
writing that any material supplier, client or customer of the Business had
made, or intends to make, a reduction in its present level of business with the
Seller as a result of this Agreement and the transactions contemplated hereby
or for any other reasons.

     5.21 Licenses. Except as disclosed on Schedule 5.21, all rights to operate
under all governmental licenses, permits, franchises and approvals and all
related vendor numbers which are required to conduct the MMIC Business, where




and as such MMIC Business is conducted ("Licenses") are, and will be
immediately before the Closing, valid and in full force and effect and

such Licenses require the consent of, or a filing or qualification with, the
permitting or licensing authority with respect to the transactions contemplated
by this Agreement.

     5.22  Collectibility of Gross Accounts Receivable. Except as indicated on
Schedule 5.22, as of the date of this Agreement the gross accounts receivable
reported on the October Balance Sheet represent valid claims against account
debtors for goods delivered or services rendered by the Seller. To the Seller's
knowledge, except as set forth on Schedule 5.22 as of the date of this
Agreement there is no reason why all such gross accounts receivable will not be
collected in the ordinary course of business, and as of the date of this
Agreement such gross accounts receivable are not subject to set-off or
counterclaim.

     5.23. Investment Representations.

     (a) Purchase Entirely for Own Account. This Agreement is made with the
Seller in reliance upon the Seller's representation to the Buyer, which by the
Seller's execution of this Agreement the Seller hereby confirms, that the
Shares to be acquired by the Seller will be acquired for investment for the
Seller's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof except pursuant to the Amended
Registration Rights Agreement or the call option referred to in Section 3.3
hereof and that the Seller has no present intention of selling, granting any
participation in, or otherwise distributing the same, except pursuant to the
Amended Registration Rights Agreement or the call option referred to in Section
3.3 hereof.

     (b) Disclosure of Information. The Seller represents that it has had an
opportunity to ask questions and receive answers from the Buyer regarding the
terms and conditions of the transactions contemplated by this Agreement. The
foregoing, however, does not limit or modify the representations and warranties
of the Buyer in Article 6 of this Agreement or the right of the Seller to rely
thereon.

     (c) Investment Experience. The Seller understands that the Shares have not
been, and prior to an appropriate registration statement's becoming effective
will not be, registered under the Securities Act of 1933, as amended (the
"Securities Act"), by reason of a specific exemption from the registration
provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the investment intent and the accuracy of the Seller's
representations as expressed herein. The Seller acknowledges that it is able to




fend for itself, can bear the economic risk of its investment and has such
knowledge and experience in financial and business matters that it is capable
of evaluating the merits and risks of the investment in the Shares.

     (d) Legends. The Seller understands that the Shares may bear one or all of
the following legends:

         (i) "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
             ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR 
             HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT
             WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF 
             COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH 
             REGISTRATION IS NOT REQUIRED."

        (ii) Any legend required by the Blue Sky laws of any state to the 
             extent such laws are applicable to the shares represented by the 
             certificate so legended.

         A certificate shall not bear such legends if in the opinion of counsel
reasonably satisfactory to the Buyer the securities represented thereby may be
publicly sold without registration under the Securities Act and any applicable
state securities laws.

     (e) Restricted Securities. The Seller understands that the Shares are
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Buyer in a transaction not
involving a public offering and that under such laws and applicable regulations
such Shares may be resold without registration under the Securities Act only in
certain limited circumstances. The Seller acknowledges that the Shares must be
held indefinitely unless subsequently registered under the Securities Act or an
exemption from such registration is available.

     (f) Accredited Investor. The Seller is an accredited investor as defined
in Rule 501(a) of Regulation D promulgated under the Securities Act.

          The Buyer represents and warrants to the Seller as follows:

when executed and delivered will constitute, the legal, valid and binding
obligation of the Buyer enforceable against the Buyer in accordance with their

bankruptcy, insolvency or similar laws affecting creditors' rights generally or
by equitable principles relating to the availability of remedies.

     6.3. Non-Contravention. The execution, delivery and performance by the
Buyer of this Agreement and the other Transaction Documents will not result in
any violation of or be in conflict with its Certificate of Incorporation or
By-Laws, or any agreement, instrument, judgment, decree, order, statute, rule
or governmental regulation applicable to it, or be in conflict with or
constitute a default under any of the foregoing.

     6.4. Government Consents, Etc. Except for the approvals referred to in

the Acquired Assets pursuant to this Agreement or the consummation of any other
transaction contemplated hereby.

     6.5. Buyer's Capabilities. The Buyer intends to use the Acquired Assets as
part of a viable, ongoing business or businesses engaged in the development,
production and sale of MMICs. The Buyer has the managerial, operational and




financial capability to compete effectively in the development, production and
sale of MMICs for advanced DOD (as hereinafter defined) radar systems and is
eligible to receive the applicable DOD security clearances necessary for such
activities. The Buyer has adequate financing or financial resources available
to consummate the transactions contemplated by this Agreement.

     6.6. Brokers. No finder, broker, agent or other intermediary has worked
for or on behalf of the Buyer in connection with the negotiation or
consummation of the transactions contemplated hereby.

      6.7. Capital Stock. The authorized capital stock of the Buyer consists of

December 31, 1997, 8,497,427 shares of Common Stock of the Buyer and no shares
of Preferred Stock of the Buyer were issued and outstanding. All of the
outstanding shares of capital stock of the Buyer are duly authorized, validly

capital stock from the Buyer are outstanding, other than as set forth in the
Buyer SEC Reports (as hereinafter defined) or as set forth in Schedule 6.7
hereto. Except as set forth in the Buyer SEC Reports, there are no outstanding
bonds, debentures, notes or other obligations the holders of which have the
right to vote or which are convertible into or exercisable for securities
having the right to vote with stockholders of the Buyer on any matter. The
Buyer SEC Reports or Schedule 6.7 hereto list, and the Buyer has delivered to
the Seller true and complete copies of, all agreements, contracts or
understandings, whether oral or written, relating to shares of capital stock of
the Buyer or options, warrants or other rights to acquire capital stock of the

understandings regarding registration rights), and all such agreements,
contracts and understandings are in full force and effect.

     6.8. Authorization for Shares. The Buyer has taken all necessary action to
permit it to issue the number of Shares required to be issued pursuant to
Article 3. The Shares issued pursuant to Article 3 will, when issued, be duly
authorized, validly issued, fully paid, nonassessable and free of any
Encumbrance and no stockholder of the Buyer will have any preemptive right of
subscription or purchase in respect thereof. Assuming the accuracy of the
Seller's representations and warranties in Section 5.23 hereof, the Shares
will, when issued, be exempt from registration under the Securities Act and any
applicable state securities laws.






     6.9. Reports and Financial Statements. The Buyer has filed all reports
required to be filed with the Securities and Exchange Commission (the "SEC")
since November 1, 1996 through the date hereof (collectively, the "Buyer SEC
Reports"), and has previously furnished or made available to the Seller true
and complete copies of all Buyer SEC Reports. None of the Buyer SEC Reports, as
of their respective dates, contained any untrue statement of material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading. Each of the balance sheets (including the related
notes) included in the Buyer SEC Reports presents fairly, in all material
respects, the consolidated financial position of the Buyer and its subsidiaries
as of the respective dates thereof, and the other related statements (including
the related notes) included therein present fairly, in all material respects,
the results of operations, the changes in shareholders equity and cash flows of
the Buyer and its subsidiaries for the respective periods or as of the
respective dates set forth therein, all in conformity with generally accepted
accounting principles consistently applied during the periods involved, except
as otherwise noted therein and subject, in the case of the unaudited interim
financial statements, to normal year-end adjustments and any other adjustments
described therein. The Buyer has provided to the Seller true and correct copies
of the Buyer's unaudited consolidated statement of operations and statement of
cash flows for the nine months ended, and the Buyer's unaudited consolidated
balance sheet as of, September 27, 1997 (the "Buyer Unaudited Financial
Statements"). Such Buyer Unaudited Financial Statements present fairly in all
material respects the results of operations and cash flows for the nine months
ended, and the financial position of the Buyer and its subsidiaries as of,
September 27, 1997, all in conformity with generally accepted accounting
principles consistently applied during the period involved except as otherwise
noted therein and except for the absence of footnote disclosures, and subject
to normal year-end adjustments and any other adjustments described therein. All
of the Buyer SEC Reports, as of their respective dates, complied in all
material respects with the requirements of the Securities Exchange Act of 1934,
as amended.

     6.10.Absence of Certain Changes or Events. During the period from
September 27, 1997 to the date of this Agreement, the business of the Buyer and
its subsidiaries has been conducted only in the ordinary course, consistent
with past practice, and neither the Buyer nor any subsidiary of the Buyer has
entered into any material transaction other than in the ordinary course,
consistent with past practice, and there has not been any change in the
condition (financial or otherwise), results of operations, assets, liabilities
or business of the Buyer other than changes arising in the ordinary course of
business consistent with past practices, none of which, individually or in the




aggregate, has had, or is reasonably expected to have, a material adverse
effect on the business, operations, assets, liabilities or financial condition
of the Buyer and its subsidiaries taken as a whole.

     6.11. Registration Statements. Since the Buyer's Registration Statement on
Form S-1 dated December 13, 1993, and the amendments thereto, and the Buyer's
Registration Statement on Form S-3 dated August 4, 1995, and the amendments
thereto, the Buyer has not filed any registration statement with the SEC, other
than Registration Statements on Form S-8. The Buyer is eligible to file with
the SEC a Registration Statement on Form S-3 for shares of its Common Stock,
including the Shares.

     6.12. Registration Rights Agreement. Attached as Exhibit E-1 hereto is a
true, complete and correct copy of the Registration Rights Agreement dated
May 17, 1991 between the Buyer and certain of its stockholders, including all
amendments thereto to date (as so amended, the "Registration Rights
Agreement"). The Registration Rights Agreement constitutes the legal, valid and
binding obligation of the Buyer, enforceable against the Buyer in accordance
with its terms, and the Buyer is in compliance with all terms and conditions
thereof. The number of Registrable Securities (as such term is defined in the
Registration Rights Agreement) outstanding on the date hereof is 461,059 shares
of Common Stock of the Buyer, all of which shares are owned of record by Lucent
Technologies, Inc., which is the sole Holder (as such term is defined in the
Registration Rights Agreement) under the Registration Rights Agreement. A total
of three demand registrations remain available to Holders under Section 2 of
the Registration Rights Agreement. The right of first offer set forth in
Section 16.3 of the Registration Rights Agreement has expired.

                                   Article 11

                        Employees and Employee Benefits

     11.1.  Hiring Employees.

           (a) At the Closing, the Buyer will offer employment to all persons
      who are MMIC Business employees at Closing (including employees on leave,
      disability or workers compensation) or are subject to outstanding
      employment offers from the MMIC Business at Closing, except for any
      persons listed on Schedule 11.1 (as such schedule may be updated by the
      Buyer at the Closing, provided that the total number does not exceed 32).
      All such offers shall be for the same pay and comparable benefits as
      those in effect at Closing. Such offers and the benefits to be provided
      to the Assumed Employees shall recognize the date of hire and time of
      service with the Seller for all purposes. All employees accepting such
      offers are referred to in this Agreement as "Assumed Employees" and their
      employment with the Buyer will be deemed to have commenced immediately
      after 11:59 p.m., Dallas local time, on the Closing Date.

           (b) The Buyer agrees that, for a period of 60 days after the Closing
      Date, it will not cause any of the Assumed Employees hired by it to
      suffer "employment loss" for purposes of the Worker Adjustment and
      Retraining Notification Act, 29 U.S.C. ss.ss.2101-2109, and related
      regulations (the "WARN Act") if such employment loss could create any
      liability for the Seller, unless the Buyer delivers notices under the
      WARN Act in such a manner and at such a time that the Seller bears no
      liability with respect thereto.

           (c) Subject to the Seller having obtained the prior written consent
      of the DOJ to rehire employees of the MMIC Business pursuant to this
      Section 11.1(c), the Buyer may at any time up to ninety (90) days after
      the Closing by written notice to the Seller cause the Seller to offer
      employment to up to 32 (less the number of employees listed on Schedule
      11.1, as such schedule may be updated by the Buyer at the Closing) of the
      Assumed Employees, with such employees to be designated by the Buyer in
      the notice. All such offers shall be for the same pay and comparable
      benefits as in effect at the Closing. The persons accepting the Seller's
      offers of employment are referred to herein as the "Rehired Employees".
      In the event any persons designated by the Buyer for rehiring do not
      accept the Seller's employment offer, if the Buyer within the next thirty




      (30) days terminates such employees' employment and the Buyer is
      responsible for severance to such employees consistent with Section
      11.2(b) below, the Seller shall reimburse the Buyer for such severance.
      In addition, in the event that by the 90th day after the Closing the
      Seller has not obtained the prior written consent of the DOJ to rehire
      employees of the MMIC Business pursuant to this Section 11.1(c), the
      Buyer may by written notice to the Seller designate up to 32 (less the
      number of employees listed on Schedule 11.1, as such schedule may be
      updated by the Buyer at the Closing) of the Assumed Employees that the
      Buyer intends to terminate within the next thirty (30) days. In the event
      that the Buyer within such thirty (30) day period terminates such
      employees' employment and the Buyer is responsible for severance to such
      employees consistent with Section 11.2(b) below, the Seller shall
      reimburse the Buyer for such severance.

     11.2.  Benefit Plans Generally.

           (a) Liabilities Generally. Except as expressly provided in this
      Agreement, Seller shall retain exclusive liability and responsibility for
      providing any and all benefits due and payable to or in respect of all
      employees of the MMIC Business and related participants and beneficiaries
      under any ERISA Plan or Non-ERISA Plan in accordance with the terms of
      such plans and applicable law.

           (b) Benefits Maintenance. Commencing as of the Closing Date and
      continuing through December 31, 1998 (the "Benefits Continuation
      Period"), with respect to the Assumed Employees and dependents and
      beneficiaries thereof, Buyer shall provide compensation, employee welfare
      plans, stock-based incentive plans and other employee benefits which are
      substantially comparable in the aggregate to the compensation paid by the
      Seller, and the plans and other benefits provided (without application of
      any exclusion for a pre-existing condition) by applicable ERISA and
      Non-ERISA Plans, immediately prior to the Closing Date, valuing any
      stock-based compensation, for this purpose, under any reasonable method;
      provided, that nothing herein shall be construed to require the Buyer to
      provide Assumed Employees with any pension benefits or retiree medical
      benefits. During the Benefits Continuation Period, the Buyer shall
      maintain severance, reduction-in-force and pay-in-lieu-of-notice benefits
      for the Assumed Employees no less favorable than the severance,
      reduction-in-force and pay-in-lieu of notice benefits provided to such
      Assumed Employees by Seller immediately prior to the Closing Date and
      disclosed on Schedule 5.10(a) or (b).




     11.3  Savings Plan. The Seller will retain all liability and responsibility
for the disposition of interests under the Raytheon TI Systems Savings Plan
(the "Savings Plan"), with respect to those employees (or their beneficiaries)
of the MMIC Business who, as of the Closing Date, are participants in the
Savings Plan. The Seller agrees that it will cause the accounts in the Savings
Plan of all such participants to be fully vested as of the Closing Date.
Effective as of the Closing Date, Seller shall amend the Savings Plan if and as
necessary (i) to cause the active participation of the Assumed Employees
therein to cease as of the Closing Date, and (ii) to permit Assumed Employees
to elect to take distributions (subject to applicable law) of their accounts
thereunder and, if such Assumed Employees so elect, to roll them over, directly
or otherwise, in accordance with applicable law and regulations, to an
individual retirement account or to one or more defined contribution retirement
plans qualified under Section 401(a) of the Code (the "Buyer Defined
Contribution Plans") and maintained by Buyer or one of its subsidiaries, and
the Buyer Defined Contribution Plans shall accept such rollovers (including to
the extent practicable any plan loans).

     11.4  Pension Plans. The Seller will retain all liability and 
responsibility for the disposition of interests under the Raytheon TI Systems
Employees Pension Plan and the Raytheon TI Systems Supplemental Pension Plan
(collectively, the "Pension Plans"), with respect to those employees (or their
beneficiaries) of the MMIC Business who, as of the Closing Date, are 
participants in either of the Pension Plans. Effective as of the Closing Date,
Seller shall amend the Pension Plans to recognize as service with the Seller
for all plan purposes the service of the Assumed Employees with the Buyer, if
any, in the Benefits Continuation Period, to recognize as compensation paid by
the Seller any compensation paid the Assumed Employees by the Buyer for
services rendered in the Benefits Continuation Period, and to recognize, for
those Assumed Employees who have at least 15 years of service and are at least
age 50 as of the Closing Date, the Seller's "Bridge to Retirement" additional
service time benefit, provided the Buyer shall have timely complied with any
information request the Seller shall reasonably make to effect all such
recognitions. The Seller further agrees that it will cause the accrued benefit
of each such employee under the Pension Plans as of the Closing Date and
through the Benefits Continuation Period to be fully vested as of the Closing
Date.

     11.5  Incentive Plans. Attached as Schedule 11.5 hereto is a description of
the Seller's internal sales and marketing incentive plans and retention
agreements (the "Incentive Plans"). The Buyer agrees to assume as part of the
Assumed Obligations the Seller's obligations under the Incentive Plans,




including with respect to the retention agreements Seller's obligations
for the current plan year. With respect to any amounts to be paid with respect
to 1997, the Seller will pay the amounts due (as set forth in Schedule 11.5)
without giving effect to any plan requirement that the Assumed Employees remain
employees of the Seller as of February 1, 1998. The Seller agrees to either
reimburse the Buyer in cash for all disbursements made by the Buyer in
connection with the Incentive Plans or to create an accrued liability on the
Closing Balance Sheet for the amount to be disbursed.

     11.6  Stock Option Plan. Seller shall, if appropriate, cause the stock
option plans of Raytheon Company (the "Raytheon Stock Plans") to be amended and
to make adjustments and take actions (and Buyer shall take such actions as are
reasonably required to implement the same) with respect to options (including,
without limitation, incentive stock options) on Raytheon Company Common Stock
which are outstanding under the Raytheon Stock Plans immediately prior to the
Closing Date and which are held by Assumed Employees and are not vested as of
the Closing Date (the "Raytheon Options") to provide that, pursuant to the
equitable adjustment provisions of the applicable Raytheon Stock Plan, such
Raytheon Options will be converted into and represent (pursuant to a
methodology consistent with Section 424 of the Code, with respect to the values
of Raytheon Common Stock and Buyer Common Stock which are reasonably agreed to
by Buyer) the right to acquire from Buyer shares of Buyer Common Stock, with
such other amendments and adjustments proposed by Buyer as are reasonable and
appropriate consistent with Buyer's current stock option plan. These actions
and adjustments shall be made and become effective as soon as reasonably
practicable. Any liabilities or other obligations with respect to such
converted Raytheon Options shall be Assumed Obligations.

     11.7  Accrued Vacation. The Seller agrees to pay the Assumed Employees, as
promptly as practicable after the Closing, an amount equal to their accrued
vacation as of the Closing, less any required withholding.


                                   Article 12

                               Certain Covenants

     12.1.  Third Party Consents.

           (a) To the extent that any agreement constituting part of the
      Acquired Assets is not capable of being transferred by the Seller to the
      Buyer pursuant to this Agreement without the consent, approval or waiver




      of a third Person, and such consent is not obtained prior to the Closing,
      or if such transfer or attempted transfer would constitute a breach
      thereof or a violation of any law, rule or regulation in the absence of
      obtaining such an approval, nothing in this Agreement will constitute a
      transfer or an attempted transfer thereof. Each of the Buyer and the
      Seller shall use reasonable efforts at its own expense to obtain any such
      approvals.

           (b) In the event that such consents, approvals and waivers referred
      to in paragraph (a) are not obtained then the Seller and the Buyer will
      each use reasonable efforts, each at its own expense, to (i) provide to
      the Buyer the benefits and burdens of any such agreement, (ii) cooperate
      in any reasonable and lawful arrangement designed to provide such
      benefits and burdens to the Buyer without incurring any obligation to any
      other Person other than to provide such benefits to the Buyer, including
      without limitation the appointment of the Buyer as the agent of the
      Seller for purposes of such agreement, and (iii) enforce, at the request
      of the Buyer for the account of the Buyer, any rights of the Seller
      arising from any such agreement.

     12.2  Novation of Government Contracts.

           (a) As soon as practicable following the Closing, the Buyer shall
      prepare (with the Seller's assistance), in accordance with Federal
      Acquisition Regulations Part 42, (P) 42.12 and any applicable agency
      regulations or policies, a written request meeting the requirements of
      the Federal Acquisition Regulations Part 42, as reasonably interpreted by
      the Responsible Contracting Officer (as such term is defined in Federal
      Acquisition Regulations Part 42, (P) 42.1202(a)), which shall be
      submitted by Seller to each Responsible Contracting Officer, for the
      United States Government (i) to recognize the Buyer as the Seller's
      successor in interest to all the Acquired Assets constituting a
      Government Contract; and (ii) to enter into a novation agreement (a
      "Novation Agreement") in form and substance reasonably satisfactory to
      the Buyer and the Seller and their respective counsel, pursuant to which,
      subject to the requirements of the Federal Acquisition Regulations Part
      42, all of Seller's right, title and interest in and to, and all of the
      Seller's obligations and liabilities under, each such Government Contract
      shall be validly conveyed, transferred and assigned and novated to the
      Buyer by all parties thereto. The Seller shall provide to the Buyer
      promptly any information regarding the Seller required in connection with
      such request. The Seller and the Buyer shall each use all reasonable




      efforts to obtain all consents, approvals and waivers required for the
      purpose of processing, entering into and completing the Novation
      Agreements with regard to any of the Government Contracts, including
      responding to any requests for information by the United States
      Government with regard to such Novation Agreements.

           (b) In connection with obtaining the consents contemplated in
      Section 12.2(a) hereof, the Seller shall not consent to any modification
      of any Government Contract included in the Acquired Assets which would
      adversely affect the rights of the Buyer under such Government Contract
      without the prior written consent of the Buyer.

     12.3.  Access to Books and Records.

           (a) The Buyer agrees to cooperate with and to make available to the
      Seller such documents, books, records or information relating to the MMIC
      Business as of the Closing Date as the Seller may reasonably require
      after the Closing.

           (b) The Buyer agrees to preserve and protect all books, records,
      files and data referred to in paragraph (a) above for a period of six (6)
      years after the Closing Date.

           (c) The Buyer agrees not to destroy any files or records which are
      subject to this Section 12.3 (i) for the period described in clause (b)
      of this Section 12.3, and (ii) thereafter, without giving at least thirty
      (30) days' notice to the Seller. Upon receipt of such notice, the Seller
      may (A) cause to be delivered to it the files or records intended to be
      destroyed, at the Seller's expense, or (B) notify the Buyer that the
      Seller will pay the cost of storing and maintaining such files or records
      (including any necessary costs of moving such files or records to a
      location under control of the Seller).

     12.4.  Use of Raytheon TI Systems Name. The Buyer agrees that promptly
after the Closing Date it will cease using any references to the Seller,
Parent, TI or any of their respective Affiliates, including any such use in
connection with the use of existing supplies of labels, signs, letterhead and
other printed materials, except that the Buyer may use up existing stocks of
catalogs and other promotional materials so long as they are stickered so as to
indicate that the MMIC Business is no longer affiliated with the Seller.




     12.5  Non-Solicitation. After the Closing, for a period of two years from
July 2, 1997, except as provided in Section 11.1(c), the Seller shall not (a)
solicit to hire any individual who, on July 2, 1997, was an employee of the
MMIC Business, or (b) hire any individual who on July 2, 1997, was an employee
of the MMIC Business unless (in case of clause (b)) such individual has a
written offer of employment from a third Person for a like position.

     12.6  Compliance With Certain Agreements. After the Closing, the Buyer
agrees to be bound, insofar as it relates to the MMIC Business, by the
provisions of (i) the Settlement Agreement dated February 23, 1995 between
Westinghouse Electric Corporation and TI, but only to the extent included in
the Assumed Obligations, and (ii) the Supplemental Agreement, dated as of
August 28, 1997, between TI and the Seller.

     12.7. Compliance With Final Judgment. After the Closing, the Buyer agrees
to be bound by the provisions of the Final Judgment.

     12.8. Best Efforts and Mutual Cooperation. Each of the parties to this
Agreement shall use its best efforts to effectuate the transactions contemplated
hereby and to fulfill and cause to be fulfilled the conditions to closing under 
this Agreement. The parties hereto will cooperate with each other to obtain as 
promptly as possible all consents, authorizations, orders or approvals of any 
third party, whether private or a Governmental Entity, required in connection 
with the transactions contemplated by this Agreement. The parties hereto agree
to coordinate and cooperate with one another in exchanging such information and 
in executing and delivering such instruments as the others may request in 
connection with all of the foregoing.

     12.9. Move to North Building. Within one year after the Closing, the
Seller and the Buyer will cooperate to move the Acquired Assets located in the
Research East Building to an approximately 18,000 square foot facility located
in the North Building contiguous to Buyer's operations in the North Building.
The Buyer and the Seller will use reasonable efforts to effect this move in a
manner that does not unreasonably disrupt the operations of the Seller or the
Buyer. The Seller agrees to pay (up to an aggregate of $8,764,000) (a) the
Buyer's reasonable out-of-pocket expenses incurred in connection with the move
and (b) the cost of constructing demising walls and other improvements in the
North Building required to set up the Buyer's research and development
operations and separate the Buyer's business from the Seller's business, in
accordance with plans and specifications to be mutually agreed upon by the
parties. Subject to the terms of the Sublease Agreements, any leasehold
improvements resulting from such payments shall be deemed to be owned by the




Buyer as part of the Acquired Assets. As promptly as practicable after the date
of this Agreement, the Seller and the Buyer will designate appropriate
representatives to develop a timetable, budget and plans for the move and the
improvements and take other related actions.

     12.10. Collection of Certain Accounts Receivable.

     (a) After the Closing Date, the Buyer shall use reasonable efforts,
consistent with the Seller's current collection practices and procedures, to
collect all accounts receivable included in the Acquired Assets which are aged
90 days or more as of the Closing Date, including, without limitation, those
listed on Schedule 5.22 (collectively, the "Collection Receivables"). All
payments received by the Buyer from any customers obligated in respect of any
Collection Receivables shall be deemed to have been made in respect of, and
shall be applied to, the Collection Receivable of such customer bearing the
earliest date unless the customer has specified the particular account to which
a remittance pertains, in which case the credit shall be made to the account
specified.

     (b) The Buyer will not accept any returns of defective products or give
any credit for defective products with respect to any products relating to the
Collection Receivables without the Seller's prior consent, which consent shall
not be unreasonably withheld. The Buyer may accept returns of products or give
credits for products relating to the Collection Receivables for reasons other
than the products being defective. For purposes of paragraph (c) below, (i) any
Collection Receivables relating to product returns or credits made in
compliance with the first sentence of this paragraph (b) shall be considered
unpaid at the end of the applicable Collection Period (as defined below) and
(ii) any Collection Receivables relating to product returns or credits made
pursuant to the second sentence of this paragraph (b) or made pursuant to the
first sentence of this paragraph (b) but without the Seller's consent, shall be
considered paid in full.

     (c) In the event that any Collection Receivable or any portion thereof
(less applicable reserves attributable to Collection Receivables set forth on
the Closing Balance Sheet) is not paid by the first anniversary of the
recording of such Collection Receivable (the "Collection Period"), within ten
days after the end of any such Collection Period, the Buyer shall deliver to
the Seller a final statement setting forth all amounts collected by the Buyer
with respect to such Collection Receivable, and listing all Collection
Receivables (or portion thereof) remaining unpaid after the Collection Period,
after giving effect to the provisions of paragraph (b) above (the "Unpaid
Accounts"). Provided that the Buyer has complied with its obligations under




this Section 12.10, within five business days of the delivery of such statement,
the Seller will pay to the Buyer the balance of the Unpaid Accounts,
net of any reserve for uncollected accounts set forth on the Closing Balance
Sheet (as finally adjusted pursuant to Section 3.2) which has not been
previously applied to any Unpaid Account under this paragraph (c). Any amounts
collected by the Seller or the Buyer with respect to any Unpaid Accounts after
the Collection Period for such Unpaid Account shall be the property of the
Seller and the Seller may take such measures to enforce collection of the
unpaid items as the Seller shall deem necessary.

     (d) In the event that the Buyer collects more with respect to the
Collection Receivables than the total amount attributable to the Collection
Receivables (net of any reserve) on the Closing Balance Sheet (as finally
adjusted pursuant to Section 3.2), the Buyer will remit to the Seller any such
excess amount.

     12.11. Buyer's Business. Except as may be otherwise contemplated by this
Agreement or required by any of the documents listed in any Schedule to this
Agreement, the Buyer covenants and agrees that, from and after the date of this
Agreement and until the Closing, it shall carry on its business in the ordinary
course substantially in the same manner as heretofore conducted.

                                   Article 13

                                   Indemnity

     13.1. Indemnification by the Seller.

          (a) The Seller agrees to indemnify and hold the Buyer (and its
     Affiliates, directors, officers, employees and agents, and each of the 
     heirs, executors, successors and assigns of the foregoing) harmless from 
     and with respect to any and all claims, liabilities, losses, damages, 
     costs and expenses (including without limitation the reasonable fees and 
     disbursements of counsel) (collectively, "Losses"), arising out of (i) any 
     breach by the Seller of any representation or warranty made by the Seller 
     in this Agreement, (ii) any breach by the Seller of any covenant, 
     obligation or undertaking made by the Seller in this Agreement or (iii) 
     the Excluded Liabilities.

           (b) No action or claim for Losses pursuant to Section 13.1(a)(i)
      above may be brought or made unless such action or claim (a "Claim") has
      been specified in reasonable detail in a written notice from the Buyer to
      the Seller on or before the one year anniversary of the Closing, except




      for Claims arising out of any breach of the Seller of Section 5.17, which
      must be made on or before July 9, 1999, or Claims arising out of any
      breach of the Seller of Section 5.19, which must be made on or before the
      expiration of any applicable statute of limitations period.

           (c) The Buyer shall not be entitled to indemnification under Section
      13.1(a)(i) above except to the extent that the cumulative amount of
      Losses arising from Claims asserted under Section 13.1(a)(i) exceeds
      $100,000, and then only to the extent of such excess. In addition, in no
      event shall the aggregate liability of the Seller for Losses under
      Section 13.1(a)(i) exceed ten percent (10%) of the Purchase Price (as
      finally adjusted pursuant to Section 3.2) except in the case of Losses
      arising from any breach by the Seller of Section 5.17 ("Environmental
      Claims"), for which the maximum amount payable by the Seller shall be
      $10,000,000, or arising from fraud.

     13.2.  Indemnification by the Buyer.

            (a) The Buyer agrees to indemnify and hold the Seller (and its 
Affiliates, directors, officers, employees and agents, and each of the heirs,
executors, successors and assigns of the foregoing) harmless from and with
respect to any and all Losses arising out of (i) any breach by the Buyer of any
representation or warranty made by the Buyer in this Agreement, (ii) any breach
by the Buyer of any covenant, obligation or undertaking made by the Buyer in

            (b) No action or claim for Losses pursuant to Section 13.2(a)(i)

on or before the one year anniversary of the Closing.

            (c) The Seller shall not be entitled to indemnification under
Section 13.2(a)(i) above except to the extent that the cumulative amount of
Losses arising from Claims asserted under Section 13.2(a)(i) exceeds $100,000,
and then only to the extent of such excess. In addition, in no event shall the
aggregate liability of the Seller for Losses under Section 13.2(a)(i) exceed
ten percent (10%) of the Purchase Price (as finally adjusted pursuant to




Section 3.2) except in the case of Losses arising from any breach by the Buyer
of Sections 6.7 or 6.8 or arising from fraud.

     13.3.  Indemnification Procedures.

           (a) In the event that any party hereto (an "Indemnified Party")
      desires to make a claim against another party hereto (the "Indemnifying
      Party", which term shall include all Indemnifying Parties if there be
      more than one) in connection with any action, suit, proceeding or demand
      at any time instituted against or made upon it for which it may seek
      indemnification hereunder (a "Third-Party Claim"), the Indemnified Party
      shall promptly notify the Indemnifying Party of such Third-Party Claim
      and of its claims of indemnification with respect thereto; provided,
      however, that the failure to provide such notice shall not release the
      Indemnifying Party from any obligation under this Article 13 except to
      the extent such Indemnifying Party is prejudiced by such failure. Upon
      receipt of such notice from the Indemnified Party, the Indemnifying Party
      shall be entitled to participate in the defense of such Third-Party
      Claim, and assume the defense of such Third-Party Claim, and in the case
      of such an assumption the Indemnifying Party shall have the authority to
      negotiate, compromise and settle such Third-Party Claim; provided, that
      (i) the Indemnifying Party shall not be entitled to settle any such
      Third-Party Claim without the consent of the Indemnified Party unless as
      part of such settlement the Indemnified Party is released from all
      liability with respect to such Third-Party Claim and (ii) the Indemnified
      Party shall cooperate with the Indemnifying Party in connection with the
      defense of such Third Party Claim, and provide all information possessed
      by the Indemnified Party relevant to the defense or settlement of such
      Third Party Claim.

           (b) The Indemnified Party shall retain the right to employ its own
      counsel and to participate in the defense of any Third-Party Claim, the
      defense of which has been assumed by an Indemnifying Party pursuant
      hereto, but the claimant shall bear and shall be solely responsible for
      its own costs and expenses in connection with such participation.

     13.4 Scope of Indemnity. Except as provided in Article 14, each of the
Seller and the Buyer acknowledges that, except for equitable relief, including
specific performance, its sole and inclusive remedy with respect to any and all
claims relating to the subject matter of this Agreement shall be pursuant to
the indemnification provisions of this Article 13.




     13.5 Waiver of Statutory Claims. The Buyer hereby waives and releases the
Seller from any and all Losses, known or unknown, it may have under CERCLA (as
defined in Article 17) or any other statutes relating to environmental matters
now or hereafter in effect or any other statute if the assertion of a right
under such statute would circumvent the intended effect of Section 13.4. The
Seller hereby waives and releases the Buyer from any and all Losses, known or
unknown, it may have under CERCLA or any other statutes relating to
environmental matters now or hereafter in effect or any other statute if the
assertion of a right under such statute would circumvent the intended effect of
Section 13.4.


                                   Article 14

                                  Tax Matters

     14.1. General.  The Seller shall remain responsible for all Income Taxes 
(as defined in Article 17) of the Seller payable in connection with the
operation of the MMIC Business prior to the Closing. The Seller shall also
remain responsible for the filing of all related Tax Returns (as defined in
Article 17).

     14.2. Cooperation on Tax Matters; Conduct of Proceedings.

           (a) The Buyer and the Seller shall cooperate fully, as and to the
      extent reasonably requested by the other party, in connection with the
      preparation and filing of Tax Returns pursuant to this Article 14 and any
      audit, litigation or other proceeding with respect to Taxes. Such
      cooperation shall include the retention and (upon the other party's
      request) the provision of records and information which are reasonably
      relevant to such preparation and filing and to any audit, litigation or
      other proceeding relating thereto and making employees available on a
      mutually convenient basis to provide additional information and
      explanation of any material provided hereunder.

           (b) The Seller shall be responsible for defending any audit,
      litigation or other proceeding with respect to any Taxes of the Seller
      for which the Seller is wholly or partially responsible for payment
      pursuant to this Article 14 and shall have the authority to negotiate,
      compromise and settle any such audit, litigation or other proceeding.

     14.3. Allocation of Transfer and Property Taxes. (a) All excise, sales,
use, value added, registration stamp, recording, documentary, conveyancing,
franchise, property, transfer, gains and similar Taxes, levies, charges and




fees including any deficiencies, interest, penalties, additions to Tax or
additional amounts excluding any Income Taxes (collectively, "Transfer Taxes")
incurred in connection with the transactions contemplated by this Agreement
shall be borne by Seller. Buyer and Seller shall use reasonable efforts to
minimize the amount of all Transfer Taxes and shall cooperate in providing each
other with any appropriate resale exemption certifications and other similar
documentation. The party that is required by applicable law to make the
filings, reports or returns and to handle any audits or controversies with
respect to any applicable Transfer Taxes shall do so, and the other party shall
cooperate with respect thereto as necessary.

     (b) All real property taxes, personal property taxes and similar ad
valorem obligations levied with respect to the Acquired Assets for a taxable
period which includes (but does not end on) the Closing Date (collectively, the
"Apportioned Obligations") shall be apportioned between Seller and Buyer based
on the number of days of such taxable period which fall on or before the
Closing Date (this and any other tax period which includes one or more days
falling on or before the Closing Date, a "Pre-Closing Tax Period") and the
number of days of such taxable period after the Closing Date (a "Post-Closing
Tax Period"). Seller shall be liable for the proportionate amount of such taxes
that is attributable to the Pre-Closing Tax Period, and Buyer shall be liable
for the proportionate amount of such taxes that is attributable to the
Post-Closing Tax Period. Upon receipt of any bill for real or personal property
taxes relating to the Acquired Assets, each of Seller and Buyer shall present a
statement to the other setting forth the amount of reimbursement to which each
is entitled under this Section together with such supporting evidence as is
reasonably necessary to calculate the proration amount. The proration amount
shall be paid by the party owing it to the other within 30 days after delivery
of such statement. In the event that either Seller or Buyer shall make any
payments for which it is entitled to reimbursement under this Section, the
other party shall make such reimbursement promptly but in no event later than
ten (10) days after the presentation of a statement setting forth the amount of
reimbursement to which the presenting party is entitled along with such
supporting evidence as is reasonably necessary to calculate the amount of
reimbursement.

     14.4.  Allowable Taxes. (a) For purposes of this Section, "Allowable Tax"
shall mean the allocable share of any Tax of Seller or any of its Affiliates
which is an allowable cost under the Federal Acquisition Regulation, 48 CFR
Chapter 1, and associated regulations and agreements between Seller and any




U.S. governmental entity, allocated based on Seller's existing finance policy
(as it is in effect on the date hereof).

           (b) If Seller has paid or reimbursed Buyer for any Allowable Tax
      which is attributable to a Pre-Closing Tax Period, Buyer agrees to repay
      to Seller promptly upon receipt any portion of such Allowable Tax that
      Buyer or any of its Affiliates is ultimately able to recover from the
      United States government.

           (c) If Buyer or any of its Affiliates receives a refund with respect
      to an Allowable Tax that is attributable to a Pre-Closing Tax Period,
      Buyer shall pay to Seller the amount of such refund reduced by the
      amount, if any, that Buyer will be required to pay to the United States
      government or suffer by reason of offset in accordance with the Federal
      Acquisition Regulation, 48 CFR Chapter 1, and associated regulations and
      agreements between Seller and any U.S. governmental entity. If Seller
      receives a refund after the Closing Date with respect to an Allowable Tax
      that is attributable to a Pre-Closing Tax Period, Seller will pay to
      Buyer the amount, if any, which Buyer will be required to pay to the U.S.
      government, or suffers by reason of an offset, in accordance with the
      foregoing regulations.

           (d) Seller and Buyer agree to cooperate with respect to the
      calculation of any amounts payable pursuant to this Section and to give
      each other written notice of events reasonably likely to result in the
      increase or decrease of any Allowable Tax attributable to a Pre-Closing
      Tax Period.

     14.5. Scope of Article 14.

           (a) Notwithstanding the provisions of Article 13, the provisions of
      this Article 14 (and not Article 13) shall govern the allocation of
      responsibility between the Seller and the Buyer for Taxes of the MMIC
      Business.

           (b) Claims under this Article 14 may be made by the Buyer and the
      Seller at any time prior to the expiration of the statute of limitations
      applicable to the Tax matter to which the Claim relates.

in Article 17); and (iii) no party shall have any liability or further
obligation to any other party to this Agreement except as provided by this
Article 15, and except that any termination of this Agreement pursuant to the
first sentence of this Article 15 shall not relieve a defaulting or breaching
party from any liability to the other party hereto. In addition, the provisions
of Article 18 shall survive any termination of this Agreement.

                                   Article 16

Government and nothing in this Agreement or the Intellectual Property Agreement

Government to receive same.

      WHEREAS, in connection with the Asset Purchase Agreement the Buyer will
issue to the Seller as partial consideration for the MMIC Business shares of
the Buyer's Common Stock, par value $.001 per share (the "Voting Stock");

      WHEREAS, in connection with the Final Order the Department of Justice has
required that the Seller place all such shares of Voting Stock received from
the Buyer into trust in order to divest itself of voting power with respect to
the Voting Stock;

      WHEREAS, the Trustee has consented to act under this Agreement in the
manner and for the purposes provided herein; and

      NOW, THEREFORE, in consideration of the covenants, promises and
agreements herein which are mutually and severally made by, and to be kept,
observed and performed by the parties hereto, it is hereby agreed as follows:

      1.  Transfer of Shares of Voting Stock to Trustee.

      1.1. The Seller hereby assigns and transfers (or, promptly upon receipt
hereof, will promptly assign and transfer) to the Trustee the Voting Stock to
be received by the Trustee pursuant to the Asset Purchase Agreement (at any
time the Voting Stock then held by the Trustee hereunder, the "Shares").

      1.2. It is hereby expressly acknowledged and agreed by the parties to
this Agreement that (i) the transfer of any and all shares of Voting Stock to



the Trustee and the registration of such shares of Voting Stock in the name of
the Trustee pursuant to this Section 1 are being effected solely for purposes
of implementing this Agreement and (ii) the Trustee shall hold such shares of
Voting Stock subject to all of the provisions of this Agreement.

              2. Withdrawal or Release of Shares of Voting Stock.

      2.1. No shares of Voting Stock shall be released or withdrawn from the
trust established by this Agreement, or shall be sold, assigned or transferred,
except as directed by the Seller in compliance with this Agreement.

      2.2. The Trustee agrees to cooperate with the Seller, and to enter into
any agreement or execute any instruments required by the Seller, to effect any
sale, assignment or transfer of the Shares, all at the expense of the Seller in
accordance with Section 6. In the event that the Seller directs the Trustee to
transfer any of the Shares to the Seller, the Trustee shall not do so unless it
has received a written certification from an officer of the Seller certifying
that such transfer to the Seller does not conflict with or violate the Final
Order. No such certification shall be required for any transfer of Shares to a
third party. The Seller shall indemnify the Trustee pursuant to Section 6 below
for any losses, costs or expenses incurred by the Trustee in connection with or
as a result of any act performed by the Trustee pursuant to this Section 2 at
the request or direction of the Seller.

      2.3. In order to effect the withdrawal or release of any Shares from this
Agreement pursuant to this Section 2, or any transfer of Shares pursuant to
this Section 2, the Trustee shall promptly, upon written request by the Seller
and receipt of a certificate of the Seller if required pursuant to Section 2.2
above, take all such steps as shall be reasonably required to (i) assign and
transfer to the applicable transferee (or the Seller) the number of Shares
which are to be withdrawn, released or transferred and (ii) either (A) cause a
stock certificate or stock certificates representing such Shares to be issued
in the name of such transferee (or the Seller) or (B) deliver or cause to be
delivered to such transferee (or the Seller) the stock certificate or stock
certificates representing such Shares, together with duly executed stock powers
for the transfer of such Shares to such transferee (or the Seller).

      2.4. Upon the withdrawal, release or transfer of any Shares pursuant to
this Section 2, the Trustee shall amend Schedule 1 hereof to reflect such
withdrawal, release or transfer.

      2.5. The Trustee agrees not to effect any sale, assignment or transfer of
any Shares, or any release or withdrawal of Shares, except for a sale,
assignment or transfer, or a release or withdrawal, of Shares effected as
provided above in this Section 2.



                     3. Dividends; Proceeds upon Transfers
                           of Shares of Voting Stock.

      3.1. If the Buyer shall declare or pay a dividend on the Shares, whether
in cash or other property (other than property described in Section 3.2), the
Trustee shall pay or distribute such dividend to the Seller promptly upon
receipt of such dividend by the Trustee.

      3.2. If the Buyer shall declare or pay a dividend on the Shares in voting
capital stock (or securities convertible into or exchangeable for voting
capital stock ), or shall otherwise distribute shares of voting capital stock
(or securities convertible into or exchangeable for voting capital stock) on
the Shares, the Trustee shall (i) receive and hold such shares of voting
capital stock or other securities subject to the terms of this Agreement and
(ii) amend Schedule 1 to include such additional shares of voting capital
stock, whereupon such additional shares of voting capital stock shall for all
purposes constitute "Shares" hereunder.

      3.3. Upon any sale, assignment, conversion, redemption or other transfer
of the Shares, whether pursuant to merger, sale of the Shares, recapitalization
or reorganization involving the Shares, the Trustee will receive all
securities, cash and other property deliverable in respect of or issuable upon
such Shares, and will (i) distribute to the Seller all cash, securities and
other property (other than voting capital stock and securities convertible into
or exchangeable for voting capital stock), (ii) hold such voting capital stock
and other securities in accordance with this Agreement, and (iii) amend
Schedule 1 to include such additional shares of voting capital stock and other
securities, whereupon such additional shares of voting capital stock and other
securities shall constitute "Shares" hereunder.

      3.4. With respect to any matter for which any vote or consent is
requested from holders of Voting Stock, the Trustee agrees that it will vote
the Shares as nearly as practicable in the same proportion as the Buyer's other
holders of the applicable class of Voting Securities with respect to such
matter. The Trustee may after the date hereof and after receipt of any
additional Voting Stock in trust hereunder, at the expense of the Seller, grant
an irrevocable proxy in respect of the Shares held in trust hereunder to an
officer or other designee of the Buyer, but only if such proxy is consistent
with the preceding sentence. Any irrevocable proxy entered into by the Trustee
in accordance with this Section 3.4 shall terminate upon any sale, assignment
or transfer of such Shares, and upon any release or withdrawal of such Shares
from this Agreement.

                        4. Trustee: In General; Powers.

      4.1. The Trustee hereby accepts the trust hereunder, subject to all the
terms, provisions and conditions set forth herein, and agrees that it will
exercise the powers and perform the duties of a Trustee as set forth herein.


      4.2. The Trustee shall have full power, at any time and from time to
time, to cause certificates of shares of Voting Stock held by it as Trustee
hereunder to be transferred on the books of the Buyer into its own name as
Trustee hereunder; provided, however, that as holder of such shares of Voting
Stock the Trustee shall assume no liability as stockholder, its interest
hereunder being solely that of Trustee.

      4.3. The Trustee irrevocably shall, in person or by its nominee, in
respect of any and all such Shares held by the Trustee under this Agreement,
and subject to the terms hereof (including Section 3.4), possess and be
entitled to exercise all stockholder rights, including the right to vote and to
give any consent for every purpose as fully as any stockholder might do and to
waive any stockholder's rights or privileges in respect thereof and to consent
to any act of the Buyer, as though absolute owner of such Voting Stock, and
Trustee shall, subject to the terms hereof (including Section 3.4), exercise
all such rights in its absolute discretion. This irrevocable right to vote
shall include, without being limited, the right to vote in favor of or against
the dissolution, reorganization, merger, consolidation or recapitalization of
the Buyer.

      4.4. The Trustee is hereby expressly authorized to do any and all acts
which it deems reasonably necessary or advisable in connection with the
carrying out of the terms, provisions and conditions of this Agreement.

                             5. Trustee: Procedure.

      5.1. The Trustee may vote or may act in person, by consent or by proxy.

      5.2. The Trustee may employ counsel and agents whose reasonable expenses
and compensation shall be paid by the Trustee and shall be chargeable as a
proper expense to the Seller, as provided in Section 6.2 hereof.

      5.3. The Trustee may resign as Trustee hereunder upon delivery to the
Seller of a letter stating the intention of the Trustee to resign and stating
the date (which shall be not less than ten days after the date of delivery of
such letter) of the effectiveness of such resignation. A successor Trustee
shall be named by the Seller on or prior to such tenth day.

              6. Trustee: Compensation, Expenses, Indemnification.

      6.1. The Trustee shall be entitled to compensation for services rendered
or duties performed under this Agreement as provided in Schedule 2 hereto.

      6.2. (a) The Seller shall reimburse the Trustee upon request for all
     reasonable disbursements and expenses incurred or made by it in connection
     with the performance of its duties hereunder. Such expenses shall include
     the reasonable compensation, disbursements and expenses of the Trustee's
     agents and counsel.




           (b) The Seller shall indemnify the Trustee against any and all
     losses and liabilities incurred by it arising out of or in connection with
     the acceptance or administration of its duties under this Agreement,
     including liabilities incurred by Trustee in connection with the
     enforcement of this Agreement against the Seller (including this Section
     6), and in connection with defending itself against any claim asserted by
     any third party. The Trustee shall notify the Seller promptly of any claim
     for which it may seek indemnity. Any failure or delay by the Trustee so to
     notify the Seller shall not relieve the Seller of its obligations
     hereunder, except to the extent the Seller is actually disadvantaged by
     such failure or delay. The Seller shall have the right to control any
     litigation arising out of any such claim (including the selection of
     counsel reasonably acceptable to the Trustee in respect thereof). The
     Trustee may engage one counsel of its choice to participate in any
     litigation arising out of any such claim (subject to the foregoing
     sentence), and the Seller will reimburse the Trustee for any reasonable
     costs of such counsel's participation.

           (c) The obligations of the Seller under this Section 6 shall survive
     the resignation or removal of the trustee and the satisfaction and
     discharge or termination of this Agreement.

           (d) Notwithstanding subparagraphs (a) or (b) above, the Seller need
     not reimburse any expense or indemnify against any loss or liability
     incurred by the Trustee or the Trustee's agents or counsel through its or
     their own gross negligence or willful misconduct. The Trustee shall not be
     liable to any Seller for any act or failure to act under this Agreement,
     except for any such act or failure to act that constitutes willful
     misconduct or gross negligence.

      6.3. The Trustee shall not incur or be subject to any liability or
responsibility as stockholder, trustee or otherwise by reason of any act,
failure to act, error of judgment, error of law or other error under this
Agreement, except for its own gross negligence or willful misconduct.

      6.4. The Trustee shall not be required to give any bond for the faithful
performance and discharge of its duties hereunder.

                             7. Successor Trustees.

      7.1. In the event of the death, disability, resignation or refusal to act
of the Trustee under the provisions of this Agreement, a successor Trustee
shall be designated or appointed by the Seller.

      7.2. Any successor Trustee appointed or designated under the provisions
of this Section 7 shall succeed to and have all of the rights, powers,
privileges and duties of the Trustee named herein, with the same force and
effect as though such successor Trustee had originally been a party to this
Agreement.




      7.3. Any corporation or association which succeeds to the corporate trust
business of the Trustee as a whole or substantially as a whole, whether by
sale, merger, consolidation or otherwise, shall thereby become vested with all
the property, rights and powers of the Trustee under this Agreement, without
any further act or conveyance.

                           8. Termination; Amendment.

      8.3. This Agreement may be amended only by a written instrument signed by
the Seller and the Trustee.

                           9. Successors and Assigns.

      All of the terms, provisions and conditions of this Agreement shall apply
to, be binding upon and inure to the benefit of (i) the Trustee and any
successor Trustee appointed or designated under the provisions of Section 7
hereof and (ii) the Seller and its successors or assigns.

                               10. Governing Law.
