ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

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

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

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

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

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


                                      -2-
<PAGE>

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

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

<PAGE>

                                         -4-


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

     and files not relating primarily to the MMIC Business.

     1.3.   DETERMINATIONS AS TO MIXED-USE ASSETS.  The Seller and the Buyer
shall cooperate in good faith to resolve any disputes as to whether any specific
assets (including, without limitation, any contracts and agreements) of the
Seller which relate to both the MMIC Business and another business of the Seller
are used primarily in, or relate primarily to, the MMIC Business.  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


<PAGE>

                                         -5-

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
                         ASSUMPTION OF CERTAIN OBLIGATIONS

     At the Closing, the Buyer shall assume, and agree to pay, perform, fulfill
and discharge, all obligations and liabilities of the Seller relating primarily
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,
(i) liabilities for Indebtedness (as defined in Article 17) of the Seller,
(ii) those liabilities for Taxes (as defined in Article 17) that remain the
responsibility of the Seller pursuant to Article 14, (iii) those liabilities of
the Seller under its pension and health and welfare benefit plans retained by it
pursuant to Article 11, and (iv) liabilities of the Seller under the Settlement
Agreement dated February 23, 1995 between Westinghouse Electric Corporation and
TI, other than the obligations restricting the sale of the F-22 ASEA product
referred to therein with respect to the MMIC Business (which obligations shall
be an Assumed Obligation) (collectively, the "EXCLUDED 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

<PAGE>

                                         -6-

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 [cad 240](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
<PAGE>

                                         -7-


     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.

<PAGE>

                                         -8-

            (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

<PAGE>

                                         -9-

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

by this Agreement (the "CLOSING") shall be held at the offices of Bingham Dana
LLP, 150 Federal Street, Boston, Massachusetts, on the fifth business day
following completion of the regulatory approval referred to in Sections 7.1 and
7.2, but in any case on or before January 26, 1998, or at such other time 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
     Price by delivery of stock certificates in appropriate form.

            (c)     The Buyer shall duly execute and deliver to the Seller such
     instruments of assumption with respect to the Assumed Obligations as the

            (b)     result in a violation by the Seller of any statute,
     regulation, order, law, ordinance or restriction applicable to the Seller,

     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.

            (h)     any lapse, termination or expiration of any contract or
     agreement, including any joint venture agreement, teaming agreement,

            (i)     any intercompany transactions relating to the MMIC Business
     with any Affiliate (as defined in Article 17) of the Seller, except (i) in

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

     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

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.

the Seller, threatened claim by any third Person of a violation, infringement,
misuse or misappropriation by the Seller in connection with the MMIC Business of
any patents, trademarks, copyrights, mask works or trade secrets owned by any
third Person, or of the invalidity of any patent included in the MMIC Business
Intellectual Property, that would, individually or in the aggregate, have a
Material Adverse Effect.  To the knowledge of the Seller, the conduct of the
MMIC Business by the Buyer following the Closing in the manner currently
conducted by the Seller will not result in the infringement of any patent,
trademark, copyright, mask work or trade secret owned by any third Person that
would, individually or in the aggregate, have a Material Adverse Effect.  There
are no interferences or other contested inter partes proceedings, either pending
or, to the knowledge of the Seller, threatened, in any domestic or foreign
copyright office, patent and trademark office or any other

     MMIC Business in violation of any Environmental Law, which circumstance,
     individually or in the aggregate, would have a Material Adverse Effect.

     (b)    Since January 1, 1994, there has been no environmental
investigation conducted of which the Seller has knowledge in relation to the

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 penalties it is required to file and such Returns were true and

date of this Agreement there are no pending or, to the Seller's knowledge,

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

for any other reasons.

     5.21   LICENSES.  Except as disclosed on SCHEDULE 5.21, all rights to

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

their respective dates, contained any untrue statement of material fact or

make the statements therein, in light of the circumstances under which they were
made, not misleading.  Each of the


<PAGE>

balance sheets (including the related notes) included in the Buyer SEC Reports

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,

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

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.

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

     11.1.  HIRING EMPLOYEES.

     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

<PAGE>
                                         -34-


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


<PAGE>
                                         -36-


     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


<PAGE>
                                         -37-


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


<PAGE>
                                         -38-


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


<PAGE>
                                         -39-


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)


<PAGE>
                                         -40-


     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
this Agreement (including the assumption referred to in Article 2), or (iii) the
operation of the MMIC Business or the use of the Acquired Assets in the
operation thereof after the Closing Date.

            (b)     No action or claim for Losses pursuant to Section 13.2(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 Seller to the Buyer
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


<PAGE>
                                         -41-


     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

     preparation and filing of Tax Returns pursuant to this Article 14 and any

     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,

     settle any such audit, litigation or other proceeding.

     14.3.  ALLOCATION OF TRANSFER AND PROPERTY TAXES.  (a)  All excise, sales,

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


<PAGE>
                                         -43-


     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

in this Agreement, no provision of this Agreement shall be construed so as to
grant Seller any license or other rights with respect to, and this Agreement
shall specifically prohibit Seller from retaining any rights with respect to,
any existing L-band intrinsic MMIC models included within the MMIC Business

or rendering unenforceable any other terms or provisions of this Agreement or
under any other circumstances or in any other jurisdiction, and the parties
shall negotiate in good faith a substitute provision which comes as close as
possible to providing the rights and obligations intended to be provided by the
invalidated or unenforceable term or provision, and puts the parties in a
position as nearly comparable as possible to the position they would have been
in but for the finding of invalidity or unenforceability, while remaining valid
and enforceable.  In the event of any conflict between the provisions of this
Agreement and the provisions of the Asset Purchase Agreement or the Supply
Agreement, the provisions of this Agreement shall be controlling; PROVIDED, that

                                                              PURCHASE AGREEMENT


                                   SUPPLY AGREEMENT


     THIS SUPPLY AGREEMENT (this "AGREEMENT"), dated as of this 13 day of
January, 1998 (the "CLOSING DATE"), is made by and between Raytheon TI Systems,
Inc., a Delaware corporation having a place of business at 13510 N. Central
Expressway, Dallas, Texas 75243 (hereinafter "RTIS"), and TriQuint Semiconductor
Texas, Inc., a Delaware corporation having a place of business at 2300 N.E.
Brookwood Parkway, Hillsboro, Oregon  97124 (hereinafter "SUPPLIER").

     WHEREAS, RTIS and TriQuint Semiconductor, Inc., a Delaware corporation and
sole shareholder of Supplier ("TRIQUINT"), are parties to an Asset Purchase
Agreement dated as of January 8, 1998 (the "ASSET PURCHASE AGREEMENT"),
pursuant to which RTIS has sold to Supplier (as assignee of TriQuint), and
Supplier (as assignee of TriQuint) has purchased from RTIS, substantially all
the assets relating to the MMIC Business (as such term is defined in the Asset
Purchase Agreement);

     WHEREAS, the MMIC Business has historically provided microwave monolithic
integrated circuits ("MMICs") and MMIC design services to RTIS; and

     WHEREAS, Supplier and RTIS desire to continue to have the MMIC Business as
operated by Supplier provide such products and services to RTIS pursuant to a
strategic supplier relationship under the terms and conditions of this
Agreement; 

     NOW THEREFORE, in consideration of the mutual covenants contained herein
and other good and valuable consideration, the parties hereby agree as follows:

                                      ARTICLE 1
                                  PRODUCT PURCHASES

     1.1.   GENERAL.  Supplier agrees to provide, and RTIS agrees to purchase,
MMIC products, including where applicable related design services (collectively,
the "PRODUCTS"), on the terms set forth herein.  

     1.2.   PRICES.  (a) The prices for Products shall be determined as set
forth in this Section 1.2 and in Section 2.3, APPENDIX A, APPENDIX B and
APPENDIX C hereto.   For a period of at least one year after the Closing Date,
Supplier agrees to continue to 

<PAGE>

                                         -2-


use the historical wafer charging systems and cost estimating systems used by
the MMIC Business immediately prior to the Closing Date for all Product orders
for RTIS.  These systems use the following three wafer processing charging
categories: (a) Development wafer account (used for the first lots of all new
designs); (b) Production wafer account (used for additional lots (beyond the
first lot) of new designs, for all repeat orders of existing designs (including
those that have minor changes, i.e., minor modifications of an existing design
where it is not considered a new design)); and (c) High Volume Production wafer
account (used for volume production orders for proven designs).  In addition,
pre-existing and pending RTIS technology development contracts and independent
research and development ("IRAD") projects have separate charging systems.

            (b)     Notwithstanding the provisions of this Section 1.2, Section
2.3, APPENDIX A, APPENDIX B and APPENDIX C, other pricing methods may be used
for future products or purchase orders subject to the written agreement of both
parties.

            (c)     Pricing with respect to Teledesic will be negotiated on an
arm's-length, non-exclusive basis.

     1.3.   PURCHASE ORDERS.  Products shall be ordered by purchase orders of
RTIS placed with Supplier, subject to acceptance by Supplier.  Supplier shall
promptly respond to all requests for quotations and all purchase orders.  If
Supplier does not accept a purchase order, it will enter into good faith
negotiations with RTIS to resolve any objections.  Supplier shall accept all
purchase orders of RTIS within Supplier's capabilities.  In the event purchase
orders are not accepted by Supplier, such purchase orders shall not be subject
to the provisions of Sections 1.5 and 2.3.  In any case where the terms of this
Agreement and the terms of any purchase order are in conflict, the terms of the
purchase order shall take precedence.  Requests for quotes and purchase orders
will follow the procedures specified in APPENDIX D attached hereto. 

     1.4.  DELIVERY AND PAYMENT.  All Product shall be delivered F.O.B. at
Supplier's Plant at Dallas, Texas, unless otherwise specified in the applicable
purchase order.  Supplier will submit invoices to RTIS for each shipment of MMIC
wafers and die at the time of shipment.  Payment terms for such shipments are
net thirty (30) days F.O.B. shipping point.  Supplier will submit invoices to
RTIS for design and general labor services on a monthly basis.  Payment terms
for such services are net thirty (30) days from the date of the invoice.

     1.5.   EXCLUSIVE RIGHT TO ORDERS.  RTIS agrees that Supplier shall have
the exclusive right to RTIS orders for production procurement for all existing
Product designs (a)(i) for which the mask works were completed as of the Closing
Date or (ii) for which new mask works are required for any updated existing
designs (whether 

<PAGE>

                                         -3-


due to conversion to 100mm, design modification or design iteration) and
(b) which meet the pricing criteria of Section 1.2 hereof, RTIS performance
criteria and reasonable schedule requirements.  RTIS anticipates ordering
production quantities of the devices listed in APPENDIX E; the listed device ID
numbers are subject to change prior to the order date.  RTIS is not obligated to
submit to Supplier requests for bids on other Product designs (including new
design starts), but may elect to do so in its sole discretion.  The terms of
this Section 1.5 shall not survive in the event of any extension or renewal of
this Agreement beyond its initial two year term pursuant to Article 7, unless
otherwise agreed to by the parties at the time such extension or renewal is
agreed to.

     1.6.   ENHANCEMENTS AND ADVANCED DEVELOPMENTS.  By mutual agreement, RTIS
may contract with Supplier for Product technology enhancements and/or advanced
Product technology developments required by RTIS.  Subject to the provisions of
Section 4.4, ownership of technology developed under such contracts will be
determined on a case-by-case basis and documented in the related purchase order.

     1.7.   MOST ADVANCED TECHNOLOGY.  Subject to any applicable licenses or
restrictions, in supplying Products and services to RTIS hereunder, Supplier
shall use its reasonable efforts to provide or use (as applicable) the most
advanced technology available to it.

     1.8.   CHANGES IN SUPPLY OR DEMAND.  Supplier will endeavor to provide
RTIS with at least ninety (90) days advance notice of material changes in its
ability to supply Products hereunder.  RTIS will endeavor to provide Supplier
with at least ninety (90) days advance notice of material changes in its
requirements for Products hereunder.  Unless otherwise mutually agreed by
Supplier and RTIS, none of the foregoing notices shall be deemed to modify any
purchase orders which have been accepted by Supplier.

     1.9.   GOVERNMENT CONTRACT FLOWDOWN.  To the extent RTIS is required to
flowdown these provisions to subcontractors, Supplier agrees to accept purchase
order provisions corresponding to all of RTIS's higher-tier subcontract or
prime-contract provisions.  These purchase order provisions will be
appropriately tailored for subcontract use of Federal Acquisition Regulation
("FAR") clauses, Defense Federal Acquisition Regulation Supplement clauses,
other agency FAR supplement clauses and other clauses that appear in the prime
or higher-tier contract(s) or as are otherwise required by law and regulation.

     1.10.  WORK IN PROCESS.  Supplier and RTIS agree to identify and document
all Supplier work in process existing on the Closing Date which is attributable
to an RTIS order.  RTIS will use its reasonable efforts to issue purchase orders
for the identified work to be completed for all such work in process within
thirty (30) days 

<PAGE>

                                         -4-


after the Closing Date, and in any event will issue all such purchase orders
within sixty (60) days after the Closing Date, PROVIDED, THAT Supplier shall
continue to process all such work in process without delays, whether or not a
purchase order has been prepared.  RTIS purchase orders must be issued and
accepted before work in process is delivered.  The price for such work in
process shall be determined in accordance with Section 1.2.

     1.11.  RTIS DEVELOPMENT CONTRACTS AND IRAD PROJECTS.  For RTIS development
contracts and internal research and development ("IRAD") projects in existence
as of the Closing Date, including, without limitation, any outstanding proposals
for such contracts and projects that are at least 75% complete as of the Closing
Date (including, without limitation, the contracts and projects listed on
APPENDIX C hereto), (a) Supplier shall accept orders to complete existing work
in process or work in backlog; (b) Supplier shall accept orders for all new
research and development work where RTIS, with MMIC Business participation, has
previously delivered a proposal to a customer, or is in the process of
delivering a proposal to a customer that is at least 75% complete as of the
Closing Date, or where RTIS has a funded IRAD project in its 1998 plan as of the
Closing Date; (c) subject to Section 1.3 of this Agreement, Supplier shall
accept orders for all new research and development work that is a direct
follow-on (next phase) to the contracts and projects listed in APPENDIX C
hereto; and (d) RTIS and Supplier agree to negotiate participation or support
for any new development contracts or IRAD projects that are not follow-on
programs to those programs listed in APPENDIX C hereto on a case-by-case basis,
PROVIDED, that Supplier is not obligated to support any new development
contracts or IRAD projects other than those described in clauses (a), (b) and
(c) above.  The fulfillment of all contracts having to do with the Supplier's
processing, characterization and analytical equipment (including epitaxial
equipment) in support of RTIS development and IRAD contracts is contingent upon
finding a solution agreeable to both parties concerning the operation and
maintenance of such equipment.  In the event that Supplier chooses to sell the
equipment instead of moving it to the North Building as contemplated by the
Sublease Agreements, RTIS shall have a right of first refusal to purchase such
equipment on terms to be agreed.

                                      ARTICLE 2
                           TECHNICAL RESOURCES AND SUPPORT

     2.1.   TECHNICAL RESOURCES.  RTIS and Supplier each agree to assign
technical personnel, and make available other technical resources, to each
Product development project ordered by RTIS hereunder consistent with the task
responsibility specified in the related purchase order.

     2.2.   RELEASED PROCESSES AND DEVELOPMENT.  Supplier shall support all
MMIC processes released as of the Closing Date (0.5um MESFET, 0.25 um pHEMT,
0.5um HFET, L-Band HBT and VPIN) at levels of engineering capabilities
sufficient 

<PAGE>

                                         -5-


to meet RTIS' requirements under this Agreement until Supplier provides RTIS
with notice of discontinuance pursuant to Section 3.2 below.  

     2.3.   DESIGN SERVICES.  Under purchase orders issued under this
Agreement, Supplier shall provide RTIS with design support services provided by
MMIC design engineers and technicians, including, without limitation, mask
layout and generation.  Supplier shall maintain a staff of trained and qualified
designers who have prior experience designing high performance military system
MMICs and are familiar with the design of the particular MMICs covered by the
development.  RTIS and Supplier will use reasonable efforts to define suitable
staffing assignments for each purchase order line item.  In the event Supplier
cannot provide appropriate staff, RTIS, upon notice to Supplier,  shall have the
right to withdraw the design support request and assign its own personnel to the
design.  Supplier's designers will only be used to design Products which are
intended for manufacture by Supplier except in situations where RTIS is
contractually required to provide a second source.  Supplier's design personnel
will serve on RTIS design teams and will be expected to attend and support
program reviews, attend team meetings, conduct design reviews, participate in
peer design reviews, write progress reports, and account for all labor charged
to the development.  Supplier shall comply with all labor charging practices and
procedures required of Department of Defense contractors.  Supplier's design
personnel time shall be charged at a rate of ____* per hour in 1998 and
____* per hour in 1999.  RTIS will provide periodic forecasts for Supplier's
design staff, updated at least quarterly, and will order design services
pursuant to a purchase order.  RTIS intends to use Supplier design personnel for
a minimum of 60% of its new designs and design modifications (i.e., existing
designs requiring new mask works) in 1998 and a minimum of 30% in 1999;
provided, that the foregoing calculation does not include digital GaAs MMIC
designs (HI2L), as Supplier does not have capability for such designs.

     2.4.   OTHER SUPPORT.  During the term of this Agreement, Supplier will
provide to RTIS the support functions and services specified on APPENDIX B
attached hereto on the terms and conditions specified for such function or

                                      ARTICLE 3
                          PROCESS CHANGES AND DISCONTINUANCE

     3.1.   PROCESS CHANGES.  Supplier shall notify RTIS in advance of any GaAs
fabrication process changes which change the baseline process as defined in the
RTIS product assurance program document setting forth the specifications
applicable to the MMIC Business (the "PRODUCT ASSURANCE PROGRAM").  RTIS will
respond to such Supplier notifications within thirty (30) days regarding
supporting data and any qualification requirements prior to implementation of
the change in the manufacture of RTIS Products.  In addition, Supplier shall
notify RTIS as soon as possible in advance, or if not possible in advance then
as soon as possible thereafter, in the case of any key GaAs fabrication process
changes which do not change the baseline process as defined in the Product
Assurance Program to which RTIS may respond at its option.  Supplier will ensure
that all process revisions and changes can be traced to specific wafer lots of
Products in both cases.

     3.2.   PROCESS DISCONTINUANCE.  Supplier may discontinue (i) any released
process used to manufacture a Product previously made or currently being made by
RTIS, or (ii) new technology for the RTIS programs referred to in Section 2.2 in
progress prior to the date hereof, with 180 days prior written notice to RTIS. 
Upon receipt of such notice from Supplier, RTIS may request quotes and submit
purchase orders with delivery of Product scheduled to occur before the
expiration of such 180 day notice period; PROVIDED, HOWEVER, that RTIS may place
one final order within the last thirty days of the 180 day notice period and
Supplier will accept and schedule such order for delivery at Supplier's
discretion at the agreed-to price.  

     3.3.   LICENSE OF PROCESS INFORMATION AFTER DISCONTINUANCE.  RTIS has the
right to license process technology and associated MMIC Business Intellectual
Property relating to any manufacturing process discontinued by Supplier under
this Agreement as set forth in Section 3.2(b)(ii)(b) and Section 3.2(e) of the
Intellectual Property Assignment, License and Sublicense Agreement between RTIS
and the Supplier of even date herewith (the "INTELLECTUAL PROPERTY AGREEMENT").

                                      ARTICLE 4
                       DESIGNS AND OTHER INTELLECTUAL PROPERTY

     4.1.   DESIGN GUIDELINES.  RTIS will use its commercially reasonable
efforts to submit purchase orders hereunder only for Products which are
consistent with Supplier's design guidelines and MMIC technologies.  Supplier
shall inform RTIS as soon as reasonably practical of any changes in Supplier's
design guidelines and supported technologies.  Notwithstanding Section 1.3,
Supplier has no obligation to support designs which do not conform to its design
guidelines and MMIC technologies.  

     4.2.   CHANGES IN DESIGNS.  RTIS may change from time to time any of the
drawings, specifications or instructions for work covered by a purchase order,
and


<PAGE>
                                         -7-


Supplier shall comply with such change notices.  If such changes result in a
decrease or increase in Supplier's cost that are directly attributable and
incurred as a result of such changes or in the time for performance, an
adjustment in the price and time for performance may be made by mutual written
agreement of the parties, provided, however, that Supplier notifies RTIS of the
request for such adjustments within thirty (30) days after receipt by it of the
change notice.

     4.3.   STATUTORY COMPLIANCE AND DESIGN RIGHTS.  Rights to existing designs
shall be as set forth in the Intellectual Property Agreement.  RTIS and Supplier
agree to comply with all applicable contractual, regulatory and legal
restrictions relating to existing and new Product designs, including, without
limitation, (a) customer restrictions, (b) Department of Defense security
requirements (including, without limitation, Special Access Required (SAR) and
Sensitive Compartmented Information (SCI) programs, (c) Department of Defense
Low/Counter Low Observable (LO/CLO) independent research and development program
guidelines issued by the office of the Undersecretary of Defense for
Acquisition, May 15, 1997, and subsequent revisions thereof, (d) provisions of
the Settlement Agreement dated February 23, 1995 between Westinghouse Electric
Corporation and Texas Instruments Incorporated relating to F-22 transmit/receive
module MMICs and (e) all applicable laws, regulations and guidelines regarding
export or re-export of products and/or technical data made available by one
party to the other pursuant to this Agreement.

     4.4.   RIGHTS TO NEW DESIGNS.  Notwithstanding anything to the contrary in
Section 1.6 hereof, RTIS shall own all Product designs (including, without
limitation, the product specification, design database, circuit files, mask
works, wafer probe test programs, wafer probe test fixtures and all associated
data), exclusive of designs having existing mask works as of the Closing Date,
covered by RTIS purchase orders under this Agreement.  Supplier shall have no
right to use any such Product designs (or make cosmetic changes to any such
Product designs) for offer or sale to third parties.  RTIS agrees that Supplier
shall retain rights to Supplier's standard cells and Supplier's circuit elements
which may be used in any Product design, and that Supplier may use such cells
for its own benefit or for the benefit of third parties.  In addition, RTIS
agrees that Supplier retains the right to re-use circuit elements of Product
designs created pursuant to Section 2.3 of this Agreement, but not to re-use any
standard cells or circuit elements furnished by RTIS.

     4.5.   RTIS PROPERTY.  Supplier shall preserve all process and test data,
mask sets, special drawings, dies, patterns, tooling or other items supplied or
paid for by the RTIS Module Business (as defined in the Final Judgment referred
to in the Asset Purchase Agreement) in good condition; except to the extent
transferred pursuant to the Intellectual Property Agreement, such items are the
property of RTIS unless otherwise specified.  Items owned or provided by RTIS
shall be returned in good condition after the work on the order has been
completed or terminated upon request


<PAGE>
                                         -8-


of RTIS or as otherwise stated in the applicable purchase order.  No mask set,
special drawing, die, pattern, tool, standard cell, circuit element or other
item owned by RTIS or a third party that does not constitute MMIC Business
Intellectual Property, Seller Intellectual Property or TI Licensed Intellectual
Property (as such terms are defined in the Intellectual Property Agreement)
shall be used by Supplier for any purpose other than supplying RTIS, without
Supplier first obtaining the written consent of RTIS thereto.

                                      ARTICLE 5
                                       WARRANTY

     5.1.   WARRANTY.  Products supplied by Supplier hereunder shall conform to
the product acceptance requirements for such Product included in the applicable
purchase order, statement of work or product specifications.  This warranty
shall be effective for a period of one hundred and eighty (180) days from the
date of delivery of the Products to RTIS.  All articles and material returned to
Supplier under warranty hereunder shall be at Supplier's expense.  For warranty
purposes, Supplier will make process control data, inspection and test reports
covering the articles or goods and their parts available for review and subject
to examination by RTIS or its authorized representatives to verify conformance
to the applicable specifications and drawings.  

     5.2.   INSPECTION.  For warranty purposes, applicable inspection may be
performed at RTIS's option on a statistical sampling basis done in accordance
with industry standards or as otherwise set forth in a purchase order.  The
entire lot may be rejected based on defects revealed by such sampling.  At
RTIS's option, the rejected lot will be returned to Supplier for  replacement or
repair of any defective units or wafers at Supplier's option.  The initial
inspection performed at RTIS on receipt of material is a conditional acceptance,
and shall not waive the right of RTIS to return material to Supplier which
exhibits or develops defects due to latent causes during the warranty period.

     EXCEPT AS SET FORTH IN SECTION 5.1, SUPPLIER DISCLAIMS ALL OTHER
WARRANTIES, EITHER EXPRESS OR IMPLIED, WITH RESPECT TO THE PRODUCTS AND SERVICES
DELIVERED TO RTIS HEREUNDER, INCLUDING WITHOUT LIMITATION, WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

     IN NO EVENT SHALL SUPPLIER'S TOTAL AGGREGATE LIABILITY TO RTIS WITH RESPECT
TO ANY PURCHASE ORDER ARISING OUT OF OR RELATING TO THIS AGREEMENT EXCEED THE
AGGREGATE AMOUNTS PAID BY RTIS TO SUPPLIER UNDER SUCH PURCHASE ORDER.


<PAGE>
                                         -9-

COST OF PROCUREMENT OR SUBSTITUTE GOODS, OR ANY OTHER SPECIAL, INDIRECT,
RELIANCE, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, HOWEVER CAUSED AND UNDER ANY
THEORY OF LIABILITY, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), OR
OTHERWISE.  THE FOREGOING LIMITATIONS SHALL APPLY REGARDLESS OF WHETHER THE
PARTY AGAINST WHOM LIABILITY IS ASSERTED HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED
REMEDY.

non-disclosure or confidentiality agreements entered into between them in the
future relating to specific programs, and agree that confidential information of
either party used in connection with this Agreement shall be subject to the
terms thereof. 

     6.2.   INSPECTION RIGHTS.  RTIS, through its authorized financial and
legal advisors, shall have the right to inspect, on a confidential basis and on
reasonable notice, the books and records of Supplier to verify the accuracy of
Product Cost amounts and otherwise to confirm compliance by Supplier with the
terms of this Agreement.

written notice of such breach to the other party, or (b) (i) the filing of a
voluntary petition in bankruptcy of the other party, (ii) the passing of a

     THIS MASTER SERVICES AGREEMENT (this "AGREEMENT") is made effective as of
the opening of business on January 13, 1998 (the "CLOSING DATE") by and between
Raytheon TI Systems, Inc., a Delaware corporation ("SELLER"), and TriQuint
Semiconductor Texas, Inc., a Delaware corporation, ("BUYER").

                                      WITNESSETH
     WHEREAS, Seller and TriQuint Semiconductor, Inc., a Delaware corporation
and sole shareholder of the Buyer ("TRIQUINT"), have entered into that certain
Asset Purchase Agreement dated as of January 13, 1998 (the "ASSET PURCHASE
AGREEMENT"), pursuant to which Seller has sold to Buyer (as assignee of
TriQuint) substantially all the assets of the "MMIC BUSINESS", consisting of the
"ACQUIRED ASSETS" and the "ASSUMED OBLIGATIONS" (as such quoted terms are
defined in the Asset Purchase Agreement);

     WHEREAS, on July 11, 1997, Seller purchased substantially all the assets of
the MMIC Business from Texas Instruments Incorporated, a Delaware corporation

Business as more particularly set forth herein;

     NOW, THEREFORE, in consideration of the mutual promises and agreements
herein set forth, Seller and Buyer, intending to be legally bound, hereby agree
as follows:

                                         -2-


                                      ARTICLE 1
                               NATURE OF THE AGREEMENT

     1.1    GENERAL.  The following are general terms and conditions under
which Seller will provide to Buyer certain support, services, and facilities
(collectively "SERVICES").  Services will be provided in accordance with these
general terms and conditions and in accordance with the terms and conditions and
any work authorization agreement entered into on the date hereof or in the
future between Seller and Buyer referencing this Agreement ("WORK
AUTHORIZATION").  

     1.2    WORK AUTHORIZATION.  The terms of both this Agreement and any
applicable Work Authorization shall both apply to the Services being performed. 
To the extent general terms contained herein are not specifically contradicted
by the terms of any applicable Work Authorization, the general terms in this
Agreement shall govern.  In any case where the terms of this Agreement and the
terms of a particular Work Authorization are in conflict, however, the terms of
the applicable Work Authorization shall take precedence.

     1.3    PURCHASE ORDERS.  Preprinted terms on any purchase order that may
be used between Seller and Buyer relating to the Services shall be disregarded,
whether or not they conflict with the terms of this Agreement or the terms of
any Work Authorization.

                                      ARTICLE 2
                                       SERVICES

     2.2    CHANGES; ASSIGNMENT AND SUBCONTRACTING.  Except where otherwise
specified in any Work Authorization, Seller shall retain the right in its
reasonable discretion to select, change, modify, and substitute any equipment,
materials, procedures or personnel (including vendors, suppliers, or
contractors) used in performing the Services so long as any required
specifications herein or in or pursuant to any applicable Work Authorization are
satisfied.  At its option, Seller, without the consent of the Buyer, may assign
or subcontract any or all of its rights and/or obligations hereunder which are
covered by corresponding provisions in the TI Services Agreement (or any
Supplemental Agreement entered into thereunder) to TI.  In addition, at its
option, Seller, without the consent of the Buyer, may assign or subcontract any
or all of its rights and/or obligations hereunder to Raytheon Company or any
subsidiary of Raytheon Company or any entity acquiring substantially all of the
assets of Seller or substantially all the assets of the business unit of Seller
for whom or by which any particular service is provided under any Work
Authorization.  As used herein, "subsidiary" means (i) any corporation of which
such party owns, either directly or through its subsidiaries, more than 50% of 


<PAGE>
                                         -3-


the total combined voting power of all classes of voting securities of such
corporation or (ii) any partnership, association, joint venture or other form of
business organization, whether or not it constitutes a legal entity, in which
such party, directly or indirectly, owns more than 50% of the total equity
interests.  If Seller intends to assign or subcontract its rights and
obligations hereunder or under any of the Work Authorizations as permitted by
this Section 2.2, Seller shall notify Buyer within thirty (30) days prior to
such assignment or subcontracting.  Further, any permitted assignee or
subcontractor shall be bound by the terms of this Agreement and any applicable
Work Authorization.

     2.3.   TI SERVICES.  Notwithstanding anything contained herein or in any
Work Authorization to the contrary, in the event that any Service to be provided
hereunder is to be provided by Seller pursuant to the TI Services Agreement or
Supplemental Agreement or work authorization entered into thereunder, and the TI
Services Agreement, Supplemental Agreement or  work authorization or the
applicable service thereunder is terminated, Seller shall have no further
obligation to provide such Service hereunder.

     2.4.   SUPPLY AGREEMENT.  The parties acknowledge and agree that the terms
of this Agreement shall not apply to the Supply Agreement being entered into by
the parties on or about the date hereof, or to any goods or services provided in
connection therewith.

                             STANDARD OF CARE; DISCLAIMER

     5.1    STANDARD OF CARE.  Seller hereby represents to Buyer that the
Services to be performed hereunder and under each of the Work Authorizations
shall be performed in a professional and competent manner consistent with
historical provision of such Services prior to the separation of the MMIC
Business from the other business operations of Seller.

     5.2    DISCLAIMER OF WARRANTIES.  EXCEPT AS EXPRESSLY SET FORTH IN A WORK
AUTHORIZATION, SELLER HEREBY DISCLAIMS ANY WARRANTY, EXPRESS OR IMPLIED,
INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE,
WITH RESPECT TO THE SERVICES (OR ANY SERVICES PROVIDED BY THIRD PARTIES WITH
WHOM EITHER PARTY CONTRACTS IN CONNECTION WITH THE PERFORMANCE OF THE SERVICES)
OR GOODS OR PRODUCTS FURNISHED IN CONNECTION THEREWITH.  SUCH DISCLAIMER IS NOT
INTENDED TO AFFECT ANY DIRECT CLAIMS EITHER PARTY MAY ASSERT AGAINST ANY THIRD
PARTY, NOR PREVENT THE PASS-THROUGH OR ASSIGNMENT OF ANY RIGHTS EITHER PARTY MAY
HAVE AGAINST ANY THIRD PARTY.

     5.3    ASSIGNMENT OF THIRD PARTY WARRANTIES.  To the maximum extent
allowed by law and any applicable contract, Seller hereby assigns and passes
through to the other party any warranties, express or implied, made by any third
party provider of goods or services furnished to Buyer party in connection with
the performance of the Services, and any claims and causes of action against any
such third parties.  To the extent any such warranty, claim or cause of action
is not enforceable or able to be asserted by Buyer in its own name, upon written
request, Seller through such third party shall take all reasonable action
requested by Buyer, at Buyer's cost, to enforce any such warranty or assert any
such claim or cause of action that is enforceable or assertable by Seller.

     5.4    GOVERNMENTAL APPROVALS.  Seller shall not be liable for failure to
deliver Services where such failure results from the denial of necessary
government approvals or consents, PROVIDED that Seller shall make all reasonable
efforts to obtain such approvals or consents.

     5.5    LIMITATIONS ON LIABILITY.  Notwithstanding anything to the contrary
contained herein, in no event shall Seller have any liability with respect to

SPECIAL (INCLUDING PUNITIVE OR MULTIPLE) OR CONSEQUENTIAL DAMAGE.

                                 TERM AND TERMINATION

     7.1    TERM.  This Agreement shall commence as of the Closing Date and
shall remain in effect only for so long as (i) any Work Authorization hereto
shall continue to be in effect or (ii) any Service is to be provided, pursuant
to the terms of this Agreement, whichever is longer.

     7.2    EARLY TERMINATION.  Either party may terminate its obligations
hereunder with respect to any Service with effect sixty (60) days after written
notice to the other party (the "BREACHING PARTY") that the Breaching Party is in
breach of its obligations hereunder with respect to such Service, provided the
Breaching Party has failed to cure its breach during that period.

     7.3    NO WAIVER.  This Article 7 shall not be deemed to waive, prejudice
or diminish any rights Buyer or Seller may have at law or in equity for any
breach of this Agreement.

                                      ARTICLE 8
                                    FORCE MAJEURE

     Neither party shall be responsible for any delay or failure in performance
or for any loss, damage, costs, charges and expenses incurred or suffered by the
other party by reason thereof if such delay or failure results from the
occurrence of an event beyond the reasonable control of such party and without
the fault or negligence of such party ("FORCE MAJEURE") including, but not
limited to, acts of God or the public enemy, acts of the Government in either
its sovereign or contractual capacity, fires, floods, epidemics, quarantine
restrictions, strikes, freight embargoes, unusually severe weather, failure of
suppliers, terrorism, or civil strife.  If any party to this Agreement is
rendered wholly or partially unable by an event of force majeure to carry out
its obligations under this Agreement, and if that party gives prompt written
notice and full particulars of such event of force majeure to the other party,
the notifying party shall be excused from performance of its obligations
hereunder during the continuance of any inability so caused, but for no longer
period.  Both parties shall use all commercially reasonable efforts to remove or
avoid the condition as soon as commercially practicable.

                                      ARTICLE 9
                                    GOVERNING LAW

     This Agreement and the Work Authorizations shall be governed by, construed
and interpreted and the rights of the parties determined in accordance with the

thereof.

                                       ASSIGNS

     Except as expressly provided in Section 2.2 hereof, no assignment of this
Agreement or any Work Authorization by any party hereto shall be permitted
without the prior written consent of the other party.  Notwithstanding the
foregoing, Seller may assign this Agreement and any Work Authorization to any

all or substantially all of Seller's defense electronics business.  This
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective heirs, successors and permitted assigns.

                                      ARTICLE 11
                                 ADDITIONAL DOCUMENTS

     Each party shall promptly execute and deliver or cause to be executed and
delivered such additional documents, including but not limited to the Work
Authorizations, as are reasonably required by any other party for the purpose of
implementing this Agreement.

                                      ARTICLE 12
                                  GENERAL PROVISIONS

     12.1   ENTIRE AGREEMENT.  This Agreement, the Work Authorizations and the
other Agreements referred to herein constitute the entire Agreement between the
parties with respect to the subject matter hereof, and supersede all previous
communications, representations, understandings and agreements, either written
or oral, between the parties.

     12.2   VALIDITY.  If any provision of this Agreement or of any Work
Authorization or the application thereof to any party or circumstance shall be
held to be invalid and unenforceable to any extent, the remainder of this
Agreement or such Work Authorization or the application thereof to any other
party or circumstance shall not be affected thereby and each provision shall be
valid and shall be enforced to the fullest extent permitted by law.

     12.3   INDEPENDENT CONTRACTORS.  The parties hereto shall act in all
matters pertaining to this Agreement and the Work Authorizations as independent
contractors and nothing contained herein or in any of the Work Authorizations
and no action taken with respect to the provision of the Services shall
constitute one party to be the agent, partner or joint venturer of any other
party for any purpose whatsoever.

     12.4   AMENDMENTS.  This Agreement and any Work Authorization shall be
modified only by an instrument in writing executed by duly authorized
representatives of the parties thereto.

     12.5   WAIVERS.  A waiver of breach, delay or failure to take action with
respect to any previous default or failure by a party to fulfill its obligations
under this Agreement or any Work Authorization shall not be deemed to constitute
a waiver of any other or subsequent default or failure by such party to fulfill
such obligations and shall not constitute or be construed as a continuing waiver
and/or as a waiver of other subsequent defaults or breaches of the same or other
(similar or otherwise) obligations or as a waiver of any remedy available.

     12.6   GENDER.  Words of any gender used in this Agreement or any Work
Authorization shall be held and construed to include any other gender, and words
in the singular number shall be held to include the plural, and vice versa,
unless the context requires otherwise.

     12.7   HEADINGS.  The article headings and section captions of this
Agreement or any Work Authorization are inserted for convenience only, and shall
not be deemed to constitute part thereof or to affect the construction thereof.

     12.8   CONSTRUCTION.  The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rule of strict construction will be applied against either party.

                                      ARTICLE 13
                                  INTENT OF PARTIES

     13.1   GENERAL.  Except as otherwise expressly provided herein or in a
Work Authorization, it is the intent of the parties that services performed
prior to the date hereof by Seller for the MMIC Business will continue to be
made available to Buyer as of and after the Closing Date as necessary and
desirable to promote a smooth and efficient functional separation of the MMIC
Business from the operations of Seller.

     13.2   MISCELLANEOUS SERVICES.  The parties acknowledge and agree that
there may be some services Seller provided to the MMIC Business or the MMIC
Business provided to other internal Seller customers that are not specifically
identified in this Agreement or the Work Authorizations or the other agreements
referred to herein of which Buyer or Seller may not be aware until the time such
service is needed, but which the parties are willing to continue to provide on
the terms and conditions set forth herein in order to provide for a smooth and
orderly transition by Buyer into the operation of the MMIC Business (such
services being referred to herein as "MISCELLANEOUS TRANSITION SERVICES").  As
Miscellaneous Transition Services to be provided hereunder are identified and
mutually agreed upon, Buyer and Seller shall document the inclusion of such
services hereunder by an amendment, letter agreement, or memorandum signed by
duly authorized representatives of both parties.  The terms on which such
Miscellaneous Transition Services will be provided will be substantially
consistent with the terms on which other Services are provided hereunder.

                                  (RESEARCH EAST)

Landlord, Subtenant is the Tenant and that not all of the Overleased Premises is
being subleased to Subtenant), and except that the following sections of the
Overlease shall not apply hereto:

          (a)  Article 1, Section 1.01 as to Leased Premises and Primary
               Term;

          (b)  Article 1, Section 1.04 as to Renewal Option;

          (c)  Article 1, Section 1.05 as to Transition Activities;

          (d)  Article 2, Section 2.01 as to Base Rent;

               Encumbrances (any assignment, subletting, licensing or
               mortgage rights of Subtenant under this Sublease shall be
               governed by Section 14 of this Sublease); 

          (h)  Sections 9.01 and 9.02 as to Insurance;

          (i)  Article 14 as to Taxes; and

          (j)  Article 28 as to Notices.

3.   NON-INTERFERENCE.  

     Subtenant acknowledges that Raytheon may have operations at those portions
     of the Overleased Premises other than the Sublease Premises.  Subtenant
     agrees not to interfere with such operations.  In addition, Raytheon agrees
     not to interfere with Subtenant's operations on the Sublease Premises, to
     the extent such operations are in accordance with the terms of this
     Sublease.

4.   OBLIGATIONS OF PARTIES.

     Except as to those Sections of the Overlease excepted from this Sublease
     under Section 2(b) above, Subtenant hereby agrees to perform all of the
     remaining obligations imposed on Raytheon as Lessee under the Overlease as
     to the Sublease Premises.  

<PAGE>
                                         -3-

     With respect to repairs and maintenance required of Raytheon, as Lessee
     under Article 8 of the Overlease, EXHIBIT C attached hereto sets forth an
     allocation of the repair and maintenance responsibilities that have been
     agreed shall be performed and conducted between Raytheon and Subtenant. 
     EXHIBIT C sets forth those repair responsibilities that are allocated
     solely to Raytheon, solely to Subtenant and those for which the costs are
     to be shared by both Raytheon and Subtenant.  Raytheon and Subtenant
     understand and agree that they shall work in good faith with one another to
     coordinate the repairs for which each is responsible.

     Provided that Subtenant is not in default hereunder, Raytheon agrees to use
     its best efforts to cause the Overlandlord to perform all of the
     obligations imposed upon the Overlandlord under the Overlease; however,
     Raytheon shall in no event be responsible for any failure by Overlandlord
     to perform such obligations.

     Following notice from Overlandlord to Raytheon and Subtenant that, pursuant
     to Section 24.01 of the Overlease, a default exists under the Overlease, as
     a result of any act or omission of Subtenant, then Raytheon, at its option,
     after written notice to Subtenant, may take the necessary action to cure
     said default of Subtenant within the applicable grace period of said
     Sections 24.01(a) and (b) of the Overlease.  Subtenant shall promptly
     reimburse Raytheon for any monies expended by Raytheon in curing any such
     default.  Raytheon shall invoice Subtenant for such expenses, which shall
     be reasonably documented.  Subtenant's failure to reimburse Raytheon within
     thirty (30) days after such invoice shall constitute a default by Subtenant
     under this Sublease.  

     This Sublease is subject and subordinate to the Overlease and shall
     terminate upon the expiration or earlier termination of the Overlease,
     provided that, so long as Subtenant is not in default hereunder, Raytheon
     agrees not to take any action or omit to take any action (other than the
     purchase of the Overleased Premises by Raytheon) which would cause a
     termination of the Overlease prior to the end of the term thereof, except
     with the express written consent of Subtenant.  Notwithstanding anything to
     the contrary contained herein, in the event that Raytheon purchases the
     Overleased Premises from the Overlandlord during the term hereof, this
     Sublease shall continue in full force and effect as a direct lease between
     Raytheon as landlord and Subtenant as tenant, and the provisions of the
     Overlease applicable hereto pursuant to Section 2(b) hereof shall be deemed
     incorporated herein by this reference and shall continue to apply hereto,
     notwithstanding the expiration or termination of the Overlease as a result
     of such purchase.  Raytheon agrees to indemnify and hold Subtenant harmless
     from and against any and all claims, suits, damages, liabilities and
     expenses, including reasonable attorneys' fees, arising out of Raytheon's
     use and occupancy of the Overleased Premises prior to the Commencement Date
     of this Sublease.  Subtenant agrees to indemnify and hold Raytheon harmless
     from and against any and all claims, suits, damages, liabilities and
     expenses, including reasonable attorneys' fees, arising out of Subtenant's
     use and occupancy of the


<PAGE>
                                         -4-


     portions of Overleased Premises from and after the Commencement Date under
     this Sublease.

     To the extent that the Overlandlord is given rights to inspection of, or
     access to, the Sublease Premises or to make audits or obtain documents or
     information from Raytheon, as Lessee under the Overlease, Subtenant hereby
     grants all such rights to Overlandlord such that Overlandlord shall have
     the same rights to inspections, access, audits, documents and information
     from Subtenant.

5.   TERM; CONDITION OF SUBLEASE PREMISES.  

     (a)  The term of this Sublease shall begin upon the execution date hereof
     referenced in the preamble of this Sublease (the "COMMENCEMENT DATE"), and
     shall expire upon the first to occur of (a) the termination of the
     Overlease (subject, however, to the second sentence of the fifth paragraph
     of Section 4 hereof regarding purchase of the Overleased Premises by
     Raytheon), (b) the last day of the month on which the Subtenant completes
     its move to the North Building as contemplated by Section 16 hereof and the
     Transition Agreement, (c) in the event that the Subtenant fails to give the
     termination notice referred to in the Sublease between Raytheon and
     Subtenant relating to the North Building, 90 days after the date hereof,
     and (d) one year from the date hereof.

     (b)  Subtenant agrees to accept those portions of the Overleased Premises
     to be occupied by Subtenant "as-is", "where-is" on the Commencement Date,
     and in substantially the same condition as said Overleased Premises now
     are, and Raytheon makes no representation or warranty with respect to the
     condition thereof except that the relevant portions of the Overleased
     Premises currently are in compliance with the Overlease and will be in
     compliance therewith on the Commencement Date.  

     (c)  It is expressly understood and agreed that upon expiration of this
     Sublease pursuant to clause (a) of this Section 5, the Subtenant shall have
     no further obligation to pay rent under Section 6 hereof with respect to
     any periods after the expiration of this Sublease.

6.   RENT.  During the term of this Sublease, Subtenant shall pay to Raytheon a
     monthly rental equal to the Applicable Percentage of the monthly charges
     paid by Raytheon under the Overlease for occupancy of the Overleased
     Premises, including, without limitation, the Applicable Percentage of all
     Additional Rent and Special Services Charges, Costs of Insurance (as
     defined in Section 9(a) below), increases in premiums and Taxes under
     Sections 2.02, 9.04 and Article 14 of the Overlease and Section 9(a) of
     this Sublease, but excluding Base Rent and Utility Charges (as defined
     below) (which shall be calculated and paid in accordance with Section 8
     below), which monthly rental shall be payable in advance by the first (1st)
     day of each calendar month during the term of this Sublease (or, with

     Except to the extent Utility Charges and/or Special Service Charges are
     directly invoiced to Subtenant by a third-party utility provider or by the

     promptly pay any amounts owed), Subtenant shall reimburse Raytheon for the
     Cost of Subtenant's Utilities and Special Services as metered (where
     separately metered) and as equitably allocated (where not metered),
     together with applicable sales taxes.  Subtenant shall cooperate with
     Raytheon in providing data on Subtenant's operations necessary to calculate
     such allocation.  Attached hereto as EXHIBIT D is a schedule setting forth
     the estimated monthly Utility Charges and Special Services Charges agreed
     between Raytheon and Subtenant.  Subtenant shall pay to Raytheon as

     notice).  If the estimated amount of Utility Charges paid by Subtenant for
     such period differs from the actual amount, then Subtenant shall pay to
     Raytheon any underpayment within thirty (30) days following receipt of such
     statement or Raytheon shall credit against the next rentals payable by
     Subtenant the amount of any overpayment as the case may require; provided,
     however, that if this Sublease has terminated or expired, any overpayments
     shall be remitted to Subtenant by Raytheon together with Raytheon's
     reconciliation notice.  The obligations under this Section 8 shall survive
     termination, expiration or abandonment of this Sublease.

     and shall timely pay all charges in connection with Subtenant's telephone
     usage and needs.

intended uses specified herein, and without unreasonable interference with TI's
operations or those of any other lessee or other occupant of the TI Expressway

     SECTION 2.01.  BASE RENT.

     Lessee shall pay Base Rent to Lessor in advance on the Commencement Date
and on the first day of each month thereafter, without (subject to Article 34,
below) setoff, demand, or deduction during the Lease Term.  During the first
year of the Primary Term of this Lease, the Base Rent shall be Two Hundred
Twenty-Two Thousand and No/100 Dollars ($222.000.00) per annum, payable in equal
monthly installments of Eighteen Thousand Five Hundred and No/100 Dollars
($18,500.00) per month.  During the Primary Term, the Base Rent shall be
adjusted annually on each anniversary of the Commencement Date so that Base Rent
payable during the Primary Term shall be paid as follows:

     Lease Period   Annual Rent    Monthly Rent
     ------------   -----------    ------------
     1st Year       $222,000       $18,500
     2nd Year       $414,996       $34,583
     3rd Year       $607,902       $50,666
     4th Year       $800,000       $66,667
     5th Year       $800,000       $66,667

Payment shall be made in accordance with Section 2.04 below.  Base Rent shall
include the Basic Services set forth in Section 3.01, below.

     Base Rent shall be subject to adjustment at the commencement of each
Renewal Term (in each case, "Adjustment Date") as follows:

     (a)  The base for computing the adjustment is the Consumer Price index,
published bimonthly by the United States Department of Labor, Bureau of Labor
Statistics ("BLS") in CPI DETAILED REPORT. Consumer Price Index All Urban
Consumers (CPI-U): Selected Areas, All Items Index (Dallas/Fort Worth)
(1982-1984=100) ("Index").  The number indicated in the Index for the month and
the year in which the Commencement Date occurs shall be the "Base Index."  The
number in the Index for the month and the year which is 45 days prior to the
month and the year in which the rent adjustment occurs shall be the "Current
Index."  The Current Index shall take into consideration any changes arising
from the BLS publishing data on a base period other than 1982-1984=100.

     (b)  Except as set forth in clause (c) below, forty-five (45) days prior to
each Adjustment Date, if the Current Index has increased over the Base Index,
the Base Rent for the Renewal Term (until the next rent adjustment) shall be set
by multiplying the Base Rent for the fifth year of the Primary Term by a
fraction, the numerator of which is the Current Index and the denominator of
which is the Base Index.  If the Current Index has decreased from the Index
employed at the previous Adjustment Date, the Base Rent for the Renewal Term
(until the next rent adjustment) shall be set by multiplying the Base Rent for
the fifth year of the Primary Term by a fraction, the numerator of which is the
Current Index and the denominator of which is the Base Index, such that the Base
Rent for the Renewal Term shall be less than the Base Rent for the previous
term.  Provided however, that in no case shall the Base Rent be less than the
Base Rent for the fifth year of the Primary Term.  The new Base Rent shall take
effect on the Adjustment Date and Tenant shall be provided with written notice
of such new Base Rent thirty (30) days prior to the Adjustment Date.


                                         -8-

<PAGE>

     (c)  If forty-five (45) days prior to the Adjustment Date, the Current
Index for such date is not yet available, Lessee shall pay Lessor the Base Rent
for the Primary Term as it may have been previously increased or decreased,
until such Current Index is published and available, at which time Lessee shall
pay Lessor the increase, if any, retroactively from the applicable Adjustment
Date.

     (d)  If the Index is discontinued or revised during the Lease Term, such
other government index or computation with which it is replaced shall be used in
order to obtain substantially the same result as would be obtained if the Index
had not been discontinued or revised.

     SECTION 2.02.  ADDITIONAL RENT AND SPECIAL SERVICES CHARGES.

     As additional rent ("Additional Rent"), which shall also be due on a
monthly basis and payable in accordance with Section 2.04, Lessee shall pay to
Lessor all other amounts that Lessee is obligated to pay under the terms of this
Lease, including, without limitation, Special Services Charges for Special
Services described in Section 3.02 below and requested by Lessee.

natural gas utilities consumed as Lessee's Utilities (including without
limitation any such utilities consumed to provide the heating, ventilation and
air conditioning and the fire suppression water consumed by Lessee as a Lessee's
Utility) plus (Y) reasonable cost of delivery of Lessee's Utilities incurred by
Lessor.

     Except to the extent Utility Charges (as defined below) are directly
invoiced to Lessee by a third-party utility provider (in which case Lessee shall
promptly pay any amounts owed), Lessee shall reimburse Lessor for the Cost of
Lessee's Utilities as metered (where separately metered) and as equitably
allocated (where not metered), together with applicable sales taxes (the
"Utility Charges").  Lessee shall pay to Lessor as Additional Rent, due one (1)
month in advance on the first day of every month, without setoff, demand or
deduction, an estimated amount for such Utility Charges which initially shall be
Forty-Eight Thousand Eight Hundred Thirty-Three and No/100 Dollars ($48,833.00)
per month, irrespective of the actual consumption period, based on Lessor's
Annual Utility Plan for 1997, if available, or the actual cost of the Lessee's
Utilities for calendar year 1996.

     On or before February 15, 1998 and each February 15 thereafter during the
Lease Term, Lessor shall reasonably estimate, and notify Lessee of, the amount
to be paid by Lessee as Utility Charges for each month of the ensuing twelve

calendar months after the expiration of the Research East Transition Period and
continuing quarterly on each February 15, May 15, August 15, and November 15,
Lessor shall determine and provide notice to Lessee of the actual Utility
Charges payable by Lessee for the previous three (3) calendar month period.  If
the estimated amount of Utility Charges paid by Lessee for such three (3) month
period differs from the actual amount, then Lessee shall pay to Lessor any
underpayment within thirty (30) days following receipt of such statement or
Lessor shall credit against the next rentals payable by Lessee the amount of any
overpayment as the case may require; provided, however, that if this Lease has
terminated or expired, any overpayment shall be remitted to Lessee by Lessor
together with the Lessor's reconciliation notice.  The obligations under this

Lessor and Lessee with the understanding that Lessee's Utilities will be
available for such consumption and use in the Leased Premises during the Lease
Term at volumes and pressures of such utilities historically consumed and used
by the Defense Business operations being conducted in the Leased Premises as if

non-payments to the supplier (unless such non-payment results from Lessee's
failure to reimburse Lessor for such utility service as required by this Lease),
or (b) Lessor's failure to maintain orders/contracts with a supplier for
delivery of such utility as previously consumed and used by the Defense Business
operations being conducted at the Leased Premises.  Lessor will reasonably

                        LESSEE'S ALTERATIONS AND IMPROVEMENTS

     Material Changes to the Leased Premises shall require the prior consent of
Lessor, which consent shall not be unreasonably withheld.  As used herein,
Material Change shall mean any addition, alteration, or improvement including
installation or modification of equipment (hereinafter, "Alteration"), where
such Alteration involves connections to any Lessee's Utility Systems (defined as
the Lessor-owned or controlled lines, pumps. equipment and facilities which

plumbed process gas distribution system including, without limitation: fire
suppression systems, structural modifications (including any penetrations of the
floor, roof or outside walls); electrical, gas, water, sewer, or exhaust

or any process change has or could reasonably be expected to have a material
adverse effect on the Lessee's Utility Systems, building-wide plumbed process
gas distribution system or the structural integrity of the Leased Premises or
any other portion of the TI Expressway Site.

     Lessor shall review and respond to Lessee within fifteen (15) days from
Lessor's receipt of Lessee's notice of Lessee's intent to make any Alteration
which Lessee reasonably believes could constitute a Material Change.  If Lessor
fails to respond to Lessee within said fifteen (15) day period, Lessor shall be
deemed to have approved the proposed Alteration.  Any notices made pursuant to
this Article will describe the nature of the Alteration and will include the
estimated date and time at which Lessee proposes to commence such Alteration. 
In the event Lessee uses a contractor to make any Material Change, Lessee shall
use a contractor (i) that carries at least One Million Dollars ($1.000.000) of
general liability insurance and all workers' compensation and employers
liability insurance required by applicable law with respect to the workers on
the TI Expressway Site or that is otherwise insured to Lessor's satisfaction and
whose subcontractors are likewise insured and (ii) has been approved in advance
by Lessor's Facilities Manager for the TI Expressway Site or his designee, said
approval not to be unreasonably withheld or delayed, provided, however, any
connections to Lessee's Utility Systems or to the building-wide plumbed process
gas distribution system shall be performed at Lessee's cost by or under the
direction of TI, which shall commence and complete such activity requested by
Lessee in a timely and diligent manner.  Lessor, in its discretion. may require
Lessee's contractors and their subcontractors to be bonded for projects having
an estimated cost in excess of $250,000.00 by a bond reasonably satisfactory to
Lessor.

     All Alterations, including Material Changes, shall comply with all
applicable laws, regulations, building, electrical and fire codes, as well as
with the requirements of any casualty insurer of the TI Expressway Site.

     Upon the request of Lessee, Lessor shall advise Lessee within sixty (60)
days whether it reserves the right to require Lessee to remove any Alterations
from the Leased Premises upon termination of the Lease.  If Lessee so requests
and Lessor does not so reserve the right to require Lessee to remove any
Alterations present at the time of request from the Leased Premises, Lessor may
not require Lessee to remove such Alterations from the Leased Premises upon the
expiration or sooner termination of the Lease.

     Subject to any abandonment as described in Article 23 below, all
Alterations, trade fixtures, equipment, and personal property (i) installed in
the Leased Premises after the Commencement Date at 


                                         -14-

<PAGE>

Lessee's expense, excluding, unless otherwise agreed by Lessor and
Lessee,.Alterations, trade fixtures, equipment, and personal property installed
as part of the Transition Activities, or (ii) located in the Leased Premises on
the Commencement Date and owned by Lessee ("Lessee's Property") shall at all
times remain Lessee's property and Lessee shall be entitled to all depreciation,
amortization and other tax benefits with respect thereto.  Except for
Alterations which cannot be removed without structural injury to the Leased
Premises, at any time Lessee may remove Lessee's Property from the Leased
Premises, provided Lessee repairs at its expense all damage caused by such
removal.

     Lessee shall pay for any and all such Alterations and any costs incurred in
connection therewith, including, with respect to any services provided by Lessor
as a Special Service, reimbursement of Lessor's cost as a Special Service
charge.  To the extent Lessee manages the Alteration, Lessee will obtain waivers
of all mechanic's liens which may arise as a result of such Alteration,
provided, however, if Lessee is unable to obtain any such waiver after the use
of its reasonable efforts, Lessee shall indemnify, defend, and hold harmless
Lessor from any reasonable actual cost or damage with respect to the existence
of any such mechanic's lien and shall take all necessary legal actions,
including the posting of any sums at issue with a court of competent
jurisdiction, to clear the lien within thirty (30) days after Lessee becomes
aware that the lien has been filed.  To the extent Lessee requests and Lessor
agrees to manage the Alteration, Lessor will obtain waivers of all mechanic's
liens which may arise as a result of such Alteration, provided, however, if
Lessor is unable to obtain any such waiver after the use of its reasonable
efforts, Lessor shall take all necessary legal actions, including the posting of
any sums at issue with a court of competent jurisdiction to clear the lien
within sixty (60) days after Lessor receives notice from Lessee that the lien
has been filed, except to the extent resulting from Lessee's failure to pay the
charges for the services performed that Lessee is responsible for hereunder
within thirty (30) days following delivery to Lessee of notice and demand,
either to the contractor or supplier or to Lessor.

                 ASSIGNMENTS; SUBLEASES; MORTGAGES; AND ENCUMBRANCES

     Lessee shall not assign this Lease, sublet, license, mortgage or otherwise
encumber the Leased Premises, or any part thereof, without the prior consent of
Lessor, which consent shall not be unreasonably withheld.  For purposes of
Lessor's approval under this section, both creditworthiness and non-monetary
considerations may constitute grounds for Lessor's objection.  Notwithstanding
the foregoing, neither the transfer of all or substantially all of the assets or
capital stock of Lessee, whether by merger, consolidation or otherwise, to a
person or entity with credit comparable to, or better than, that of Lessee. or
the sale or issuance of Lessee's equity securities, nor any change in percentage
of ownership, if any, of Lessee's equity securities resulting therefrom. through
a public exchange or as part of any institutional or publicly offered financing,
shall be deemed to be (i) an assignment or in any manner a transfer of the Lease
or any estate or interest therein, (ii) a sublease of Lessee's interest in the
Leased Premises, or any part thereof, (iii) a change in control or ownership of
Lessee or (iv) a breach or default under the Lease or an event which, with the
passage of time, the giving of notice, or both, would constitute a breach or
default under the Lease.  With the prior consent of Lessor, which consent shall
not be unreasonably withheld, Lessee may assign this Lease or sublease the
Leased Premises, or any portions 



                                         -15-

<PAGE>

thereof to any subsidiary, affiliate, or division of Lessee, except that
assignment to any subsidiary, affiliate or division of Lessee as may exist as of
the Commencement Date shall not require Lessor's consent.  Any purported
assignment, sublease, license, mortgage or other encumbrance entered into by
Lessee shall not relieve Lessee of its obligations under this Lease and, if not
in compliance with this Article 6, shall be void AB INITIO.


                                      ARTICLE 7

withheld, Lessee may install such exterior signs and interior signs as it may
deem necessary for the operation of its business at the Leased Premises,
including signs on portions of the TI Expressway Site other than the Leased

shall not be obligated to, upon learning of such failure, report such matters. 
The parties shall coordinate in an effort to avoid duplicate reporting of any
emergency situation.  Under no circumstances, however, shall this provision be
construed to be an assumption by Lessor of any reporting duty on behalf of
Lessee.

                                        TAXES

     Ad valorem taxes for the Leased Premises will be charged by Lessor to
Lessee during the Lease Term, and Lessee shall pay and discharge as Additional
Rent such ad valorem taxes for the Research East Building, based on Lessee's
proportionate share thereof, which shall be that percentage derived by dividing
(1) the NSF of the Leased Premises in the building (exclusive of the Exterior
Equipment Locations), by (2) the total of (a) the NSF of the Leased Premises in
the building (exclusive of the Exterior Equipment Locations); and (b) the NSF of
any TI space, if any, in the building (i.e. any net square footage in the
building that is not included in the Leased Premises).  Ad valorem taxes for a
building at a multiple building site will be determined based on the Research
East Building's pro rata share of TI Expressway Site site-wide taxes, calculated
on the basis of net book value, as reflected in the records maintained by
Lessor's Corporate Services Finance Department prepared in accordance with
disclosure statement approved by the Defense Logistics Agency/DCAA or with
generally accepted accounting principles.  Such taxes shall be due and payable
fifteen (15) days after notice from Lessor.  Lessor and Lessee shall reasonably
cooperate regarding ad valorem tax issues, and avoid actions which would result
in unfair discrimination with regard to allocation or distribution of ad valorem
taxes or the property assessments on which such taxes are based.

     Except for ad valorem taxes assessed directly on the TI Expressway Site,
all taxes and assessments now or hereinafter imposed upon Lessee with respect to
its operations or property, now or hereinafter imposed, shall be borne and
timely paid directly by Lessee to the taxing authority.

at its sole cost, may, but shall not be obligated to, enter the Leased Premises
and inspect Lessee's environmental records and operations, and sample/monitor
Lessee's waste streams, radiation and air emissions, for the sole purpose of
determining whether Lessee is in compliance with this Lease, provided that any
entry shall minimize to the extent reasonably possible any interference with the
business or operations conducted in the Leased Premises.  Lessee shall have the
right to designate a representative of Lessee to accompany Lessor and its
representatives during the audit; provided, exercise of such right does not

audit, or information learned through such audit to any third party, including
any governmental authority, without the prior consent of Lessee, except for an
emergency situation as set forth in Article 13, and except as otherwise required
by law.  Lessor shall, at Lessee's request, disclose all findings within the
scope of such audit to Lessee, and in all cases, shall provide a copy of such
audit to Lessee.  In the event Lessor discovers that Lessee is not in compliance
with applicable laws or other covenants of this Lease in any material respect,
whenever reasonably necessary Lessor may, but shall have no obligation to, take
the least disruptive action necessary to remedy such noncompliance by Lessee and
protect the legitimate interests of Lessor; provided however, except in
emergency situations, Lessor shall afford Lessee the prior opportunity to take
such action


                                         -29-
<PAGE>

within a ten (10) day period (or shorter if warranted by the circumstances)
before instituting any such action, and Lessor shall only act, if at all, if
Lessee fails to take any action within the prescribed period or fails to
diligently continue to implement such action.  In the event Lessor takes any
such remedial action, Lessor shall not be liable for inconvenience, annoyance,
disturbance, loss or interruption of business, by reason of making such
reasonable and good faith determination and taking such action; provided,
however, Lessor shall be liable to Lessee for any negligence or reckless
disregard caused by Lessor, its employees, agents, consultants, and contractors
with respect to any action under this Article 19.  Lessor agrees in exercising
its rights under this Article 19 to act in good faith to avoid unreasonable
interference with Lessee's operations at the TI Expressway Site.

                                ENTRY/RIGHT OF ACCESS

     Due to the interconnectedness of the infrastructure serving the various
buildings on the TI Expressway Site, Lessor will require and Lessee hereby
agrees to grant to authorized personnel of Lessor (i) access to certain
infrastructure and utilities systems located in those areas of the Research East
Building indicated as "TI required access" areas on Exhibit A-4 hereto, as and
to the extent reasonably required by Lessor, and (ii) the right to continue to
monitor on Lessor's supervisory control and data acquisition ("SCADA") system,
utilities and process gas and fluid distribution systems located in the Leased

purposes

     (a)  to make repairs to the Leased Premises required of Lessor under this
Lease;

     (b)  to provide access to the Leased Premises during normal business hour

<PAGE>

     (h)  to perform services for Lessee hereunder.

     Nothing herein shall be construed to impose or imply any duty upon Lessor
to do any such work which, under any provision of this Lease, it is not required
to perform; and the performance thereof by Lessor shall not constitute a waiver
of Lessee's default.  Lessee shall reasonably cooperate with Lessor to ensure
provision of keys, combinations or codes as necessary to ensure adequate and
(where appropriate) immediate access to the Leased Premises as reasonably
required to provide Lessor with the access granted, above.  Lessee shall have
the right to designate a representative of Lessee to accompany Lessor and its
representatives when Lessor or its representatives are present on the Leased

                              BUILDING SYSTEMS SHUTDOWNS

     Lessee acknowledges that Lessor may, from time to time during emergencies
or for purposes of building maintenance, need to shut down one or more of the
Utility Systems serving the buildings in which the Leased Premises are located.

     Lessee agrees to reasonably cooperate with Lessor to allow Lessor to shut
down building systems for up to five (5) days annually to perform Utilities
Systems maintenance.  Except in the case of an emergency, Lessor shall schedule
such shutdown with at least two (2) months notice to Lessee and prior approval
by Lessee, which approval shall not be unreasonably withheld or delayed.  Lessor
will cooperate with Lessee regarding all shutdowns so as to minimize any
potential disruption to Lessee's operations.

     Lessee acknowledges Utilities Systems shutdowns performed in accordance
with this Article 21 will benefit Lessee and Lessee's operations.  Lessor shall
not be liable for inconvenience, annoyance, disturbance, loss or interruption of
business to Lessee.  Lessor shall not be liable for any other claimed damage to
Lessee, by reason of any such Utilities Systems shutdown, except to the extent
due to the gross negligence or willful misconduct of Lessor or its agents,
employees, or contractors, nor shall Lessee be entitled to any abatement of Rent
by reason of any such Utilities Systems shutdown.

     If Lessee continues to occupy the Leased Premises beyond the Lease Term of
this Lease in the absence of a mutually agreed upon extended term, such
holding-over shall constitute a tenancy at will, except upon hold-over all the
monthly Rent rates shall increase to a sum of 150% of the then current Rent in

     Upon surrender of the Leased Premises for any reason, including
termination, abandonment, expiration or breach by Lessor, Lessee, at its expense
(except as otherwise expressly provided herein) shall remove from the Leased
Premises Lessee's Property, except for such Alterations that Lessor has agreed
that may at Lessee's election, be surrendered.  Lessee will use all reasonable
efforts to avoid causing damage to the surrounding structure and to minimize
disruption of Lessor's operations.  Subject to Articles 10 and 11, Lessee, at
its expense, will promptly repair any damage to the Leased Premises caused by
any removal of Lessee's property and Alterations therefrom and restore the
Leased Premises substantially to the same condition as at the commencement of
the Lease (without such equipment as Lessee is removing), reasonable wear and
tear and Alterations that Lessor states in writing may be surrendered at the
termination of the Lease excepted.  Lessor's acceptance of any surrender of the
Leased Premises by Lessee shall not be deemed to constitute a waiver by Lessor
of any default by Lessee.  Any of Lessee's Property not removed after surrender
shall become the property of Lessor.  Upon such surrender, Lessee shall not
allow or cause any environmental, health, or safety permits or authorizations
relating to Lessee's use or occupancy of the Leased Premises to expire,
terminate, or lapse for a period of sixty (60) days after such surrender and
shall, at Lessor's request, execute such documentation as may be necessary or
desirable to transfer any such permits or authorizations to Lessor or Lessor's
designee.

     (b)  For non-monetary obligations, Lessee's breach of or failure to comply
with any term, provision, representation, warranty, or covenant of this Lease,
and Lessee's failure to cure such breach or noncompliance within thirty (30)
days after actual receipt by Lessee of notice thereof from Lessor or with

     SECTION 25.01.  LESSOR'S REMEDIES.

     If an Event of Default by Lessee shall have occurred, Lessor shall have the
right, at its election, then or at any time thereafter while such Event of
Default shall continue, to pursue any one or more of the following remedies,
without any notice or demand whatsoever:

     (a)  Terminate this Lease, without any liability whatsoever, in which
event, Lessee shall immediately surrender the Leased Premises to Lessor, and if
Lessee fails to do so, Lessor may, without prejudice to any other remedy which
it may have for possession or arrearages in Rent, enter upon or take possession
of the Leased Premises and expel or remove Lessee and any other person who may
be occupying the Leased Premises or any part thereof without being liable for
prosecution or any claim for damages therefor, and Lessee agrees to pay to
Lessor, on demand, the amount of all loss and damage, including attorneys' fees,
which Lessor may suffer by reason of such termination;

     (b)  Enter upon the Leased Premises without being liable for prosecution or
any claim for damages therefor, correct such default and, upon demand, recover
from Lessee all reasonable amounts expended, as Rent; or otherwise do whatever
Lessee is obligated to do under the terms of this Lease; and Lessee agrees to
reimburse Lessor, on demand, for any expenses, including attorneys' fees, which
Lessor may incur in connection with its attempts to effect compliance with
Lessee's obligations under this Lease, and Lessee further agrees that Lessor
shall not be liable for any damages resulting to Lessee from such action, except
to the extent caused by the gross negligence or willful misconduct of Lessor; or

     (c)  Enter upon and take custodial possession of the Leased Premises, and
use reasonable efforts to re-let the Leased Premises for a use comparable to
that of Lessee for the balance of the then current term without thereby causing
a termination or anticipatory breach of the Lease.

     Pursuit of the foregoing remedies shall not preclude pursuit of any other
remedies herein provided or any other remedies provided by law or equity, nor
shall pursuit herein provided constitute a forfeiture or waiver of any Rent due
to Lessor hereunder or any damages accruing to Lessor by reason of the violation
of any of the terms, provisions or covenants herein contained.  Failure by
Lessor to enforce one or more of the remedies provided herein upon an Event of
Default by Lessee shall not be deemed or construed to constitute a waiver of
such default, or any other violation or breach of any of the terms, provisions
or covenants herein contained.

     SECTION 25.02.  LESSEE'S REMEDIES.

     If an Event of Default by Lessor shall have occurred, Lessee shall have the
right, at its election, then or at any time while such Event of Default shall
continue, to pursue any one or more of the following remedies without any notice
or demand whatsoever:

     (a)  Terminate this Lease, in which event, Lessee shall immediately
surrender the Leased Premises to Lessor, and such date of surrender shall be
treated as if it were the date set forth above for the termination of the then
current term of the Lease; provided, however, Lessee may also assert any claim
Lessee may have against Lessor for amounts due from Lessor to Lessee hereunder
or for any other breach by Lessor hereunder.  Lessor agrees to pay to Lessee, on
demand, the amount of all loss and damage, including attorneys fees, which
Lessee may suffer by reason of such termination, and provided, however, Lessee
shall at all times be entitled to remove Lessee's property and Alterations
installed and paid for by Lessee from the Leased Premises, or

     (b)  Correct such default and, upon demand, recover from the Lessor, upon
invoice, all amounts reasonably expended; or otherwise do whatever Lessor is
obligated to do under the terms of this Lease; and Lessor agrees to reimburse
Lessee promptly, on demand, for any reasonable expenses, including attorneys
fees, which Lessee may incur in connection with its attempts to effect
compliance with Lessor's obligations under this Lease, and Lessor further agrees
that Lessee shall not be liable for any damages resulting,- to the Lessor from
such action, except to the extent caused by the gross negligence or willful
misconduct of Lessee.

     Pursuit of the foregoing remedies shall not preclude pursuit of any other

     Effective January 13, 1998, RAYTHEON TI SYSTEMS, INC., a Delaware
corporation, having an address c/o Raytheon Company, 141 Spring Street,

1.   OVERLEASE; TRANSITION AGREEMENT.  As used herein, the term "Overlease"
     shall mean the July 11, 1997 Lease from Texas Instruments Incorporated (the
     "OVERLANDLORD") to Raytheon, of certain premises located at 13510 North

     As used herein, the term "TRANSITION AGREEMENT" shall mean the Transition
     Agreement, of even date herewith, between Subtenant and Raytheon.  A copy
     of the Transition Agreement is attached hereto as EXHIBIT C.

2.   SUBLEASE.

     (a)  Raytheon hereby subleases to Subtenant those portions of the
     Overleased Premises, more particularly described on EXHIBIT B attached
     hereto, subject to the terms and conditions hereof (the "SUBLEASE
     PREMISES").  Raytheon shall construct, at its sole cost and expense,
     demising walls and other improvements pursuant to plans and specifications
     to be mutually agreed upon by the parties and described generally in the
     Transition Agreement.  

     (b)  EXHIBIT B attached hereto identifies approximately 17,500 square feet

                                         -2-

     Date (as defined in Section 5), Raytheon has certain personnel and
     furniture, fixtures and equipment located within the Release Space. 
     Subtenant hereby grants Raytheon a license, revocable by written notice
     given to Raytheon at any time within ninety (90) days from the date hereof,
     to continue to use and enjoy the Release Space without disruption or
     interference by Subtenant.  At any time prior to ninety (90) days after the
     date hereof, Subtenant may, after giving Raytheon thirty (30) days prior
     written notice (the "TERMINATION NOTICE"), terminate the license for the
     Release Space and request that Raytheon vacate the Release Space within
     such thirty (30) day period after Raytheon's receipt of the termination
     notice.  Within such thirty (30) day period, Raytheon shall vacate the
     Release Space at its sole cost and expense and promptly thereafter
     construct, at Raytheon's sole cost and expense (not to exceed the maximum
     amount specified in the Transition Agreement), walls and other improvements
     with respect to the Release Space pursuant to plans and specifications to
     be mutually agreed upon by the parties and described generally in the
     Transition Agreement.  Should Subtenant fail to give the termination notice
     to Raytheon within ninety (90) days from the date hereof, then under such
     circumstances, (i) the Sublease Premises shall be reduced for all purposes
     by deleting the Release Space from the Sublease Premises, (ii) to the
     extent appropriate, Raytheon shall construct, at its sole cost and expense,
     demising walls and other improvements separating the Release Space from the
     Sublease Premises pursuant to plans and specifications to be mutually
     agreed between the parties, (iii) the Applicable Percentage of monthly
     rental provided under Section 6 below shall be reduced to 11.7%, and (iv)

     acknowledges that Subtenant may use portions of the mezzanine area for a
     lobby and miscellaneous manufacturing.

     (c)  This Sublease shall be deemed to contain all of the same covenants,
     agreements, conditions, terms and provisions as contained in the Overlease,
     MUTATIS MUTANDIS (the necessary changes being made to reflect the fact that
     Raytheon is the Landlord, Subtenant is the Tenant and that not all of the
     Overleased Premises is being subleased to Subtenant), and except that the
     following sections of the Overlease shall not apply hereto:

               (g)  Article 6 as to Assignments; Subleases; Mortgages; and
                    Encumbrances (any assignment, subletting, licensing or
                    mortgage rights of Subtenant under this Sublease shall be
                    governed by Section 14 of this Sublease); 

               (h)  Sections 9.01 and 9.02 as to Insurance; 

               (i)  Article 14 as to Taxes; and

               (j)  Article 28 as to Notices.

3.   COMMON AREAS:

     (a)  The areas color coded in blue and green on EXHIBIT B attached hereto
     are Common Areas ("COMMON AREAS") and Restricted Common Areas ("RESTRICTED
     COMMON AREAS"), respectively.  The Common Areas are those areas within the
     North Building available for use and benefit of both Raytheon and
     Subtenant.  The Restricted Common Areas are those areas within the North
     Building available for use only by individuals specifically identified and
     designated by Raytheon and Subtenant respectively.  

     (b)  Raytheon and Subtenant each acknowledge and agree that they both
     benefit from, and should share the costs and expenses associated with, the
     Common Areas and Restricted Common Areas.  Raytheon shall provide
     maintenance, repairs, cleaning and janitorial, utilities, insurance,
     equipment and supplies for the Common Areas and Restricted Common Areas as
     well as maintenance for shared systems (the "CAM COSTS").  In addition to
     the monthly rental provided in Section 6 below, Subtenant shall pay
     Raytheon monthly, as Additional Rent, an amount equal to all amounts
     estimated to be paid or incurred by Raytheon for monthly CAM Costs
     applicable to the Sublease Premises.  As of the date of this Sublease,
     Subtenant's monthly CAM Costs shall be $4,810.00.  Should Subtenant fail to
     give to Raytheon the termination notice under Section 2(b) above, then
     under such circumstances, from and after the ninety-first (91st) day after
     the date hereof, Subtenant's monthly CAM Costs shall be $4,319.00. 
     Subtenant shall pay to Raytheon, as Additional Rent, due upon execution of
     this Sublease, and on the first day of every succeeding month, the agreed
     amount for such CAM Costs as set forth in the applicable sentence of the
     two immediately preceding sentences.  This amount has been stipulated and
     agreed between the parties as fair and is agreed irrespective of the actual
     CAM Costs incurred or paid by Raytheon.  This agreed amount shall remain
     constant until revised in accordance with the immediately succeeding
     paragraph.

          (Dallas/Fort Worth) (1982-1984=100) ("INDEX").  The number indicated
          in the Index for the month and the year in which the Commencement Date
          occurs shall be the "BASE INDEX".  The number in the Index for the
          month and the year which is 45 days prior to the month and the year in
          which the rent adjustment occurs shall be the "CURRENT INDEX".  The
          Current Index shall take into consideration any changes arising from
          the BLS publishing data on a base period other than 1982-1984=100.  

          (2)  Except as set forth in clause (3) below, forty-five (45) days
          prior to each Adjustment Date, if the Current Index has increased over
          the Base Index, the CAM Costs for the next succeeding year of this
          Sublease (until the next rent adjustment) shall be set by multiplying
          the CAM Costs for the first year of this Sublease by a fraction, the
          numerator of which is the Current Index and the denominator of which
          is the Base Index.  If the Current Index has decreased from the Index
          employed at the previous Adjustment Date, the CAM Costs for the next
          succeeding lease year (until the next rent adjustment) shall be the
          same as the previous lease year.  In no case shall the CAM Costs be
          less than the CAM Costs for the previous lease year.  The new CAM
          Costs shall take effect on the Adjustment Date and Subtenant shall be
          provided with written notice of such new CAM Costs thirty (30) days
          prior to the Adjustment Date.

          (3)  If, forty-five (45) days prior to the Adjustment Date, the
          Current Index for such date is not yet available, Subtenant shall pay
          Raytheon the CAM Costs for the next succeeding year of this Sublease
          as it may have been previously increased until such Current Index is
          published and available, at which time Subtenant shall pay Raytheon
          the increase, if any, retroactively from the applicable Adjustment
          Date.

          (4)  If the Index is discontinued or revised during the term of this
          Sublease, such other government index or computation with which it is
          replaced shall be used in order to obtain substantially the same
          result as would be obtained if the Index had not been discontinued or
          revised.

     (c)  Raytheon shall have the right to prepare and revise, from time to
     time, and enforce reasonable rules and regulations for use of the Common
     Areas and Restricted

<PAGE>

                                         -5-


     Common Areas.  All such rules and regulations shall be applied to both
     Raytheon and Subtenant.

     (d)  The conference rooms in the cafeteria on the ground floor shall be
     available on a first-come, first serve basis to the Subtenant and Raytheon.
     Until changed by Raytheon, reservations for use of such conference rooms
     shall be made through the computer system provided for such purpose.

4.   OBLIGATIONS OF PARTIES.  

     Except as to those Sections of the Overlease excepted from this Sublease
     under Section 2(c) above, Subtenant hereby agrees to perform all of the
     remaining obligations imposed on Raytheon as Lessee under the Overlease as
     to the Sublease Premises.

     With respect to repairs and maintenance required of Raytheon, as Lessee
     under Article 8 of the Overlease, EXHIBIT D attached hereto sets forth an
     allocation of the repair and maintenance responsibilities that have been
     agreed shall be performed and conducted between Raytheon and Subtenant. 
     EXHIBIT D sets forth those repair responsibilities that are allocated
     solely to Raytheon, solely to Subtenant and those for which the costs are
     to be shared by both Raytheon and Subtenant.  Raytheon and Subtenant
     understand and agree that they shall work in good faith with one another to
     coordinate the repairs for which each is responsible.

     Provided that Subtenant is not in default hereunder, Raytheon agrees to use
     its best efforts to cause the Overlandlord to perform all of the
     obligations imposed upon the Overlandlord under the Overlease; however,
     Raytheon shall in no event be responsible for any failure by Overlandlord
     to perform such obligations.

     Following notice from Overlandlord to Raytheon and Subtenant that, pursuant
     to Section 24.01 of the Overlease, a default exists under the Overlease, as
     a result of any act or omission of Subtenant, then Raytheon, at its option,
     after written notice to Subtenant, may take the necessary action to cure
     said default of Subtenant within the applicable grace period of said
     Sections 24.01(a) and (b) of the Overlease.  Subtenant shall promptly
     reimburse Raytheon for any monies expended by Raytheon in curing any such
     default.  Raytheon shall invoice Subtenant for such expenses, which shall
     be reasonably documented.  Subtenant's failure to reimburse Raytheon within
     thirty (30) days after such invoice shall constitute a default by Subtenant
     under this Sublease.  

     This Sublease is subject and subordinate to the Overlease and shall
     terminate upon the expiration or earlier termination of the Overlease,
     provided that, so long as Subtenant is not in default hereunder, Raytheon
     agrees not to take any action or omit to take any action (other than the
     purchase of the Overleased Premises by Raytheon)

<PAGE>

                                         -6-

     which would cause a termination of the Overlease prior to the end of the
     term thereof, except with the express written consent of Subtenant. 
     Notwithstanding anything to the contrary contained herein, in the event
     that Raytheon purchases the Overleased Premises from the Overlandlord
     during the term hereof, this Sublease shall continue in full force and
     effect as a direct lease between Raytheon as landlord and Subtenant as
     tenant, and the provisions of the Overlease applicable hereto pursuant to
     Section 2(c) hereof shall be deemed incorporated herein by this reference
     and shall continue to apply hereto, notwithstanding the expiration or
     termination of the Overlease as a result of such purchase.  Raytheon agrees
     to indemnify and hold Subtenant harmless from and against any and all
     claims, suits, damages, liabilities and expenses, including reasonable
     attorneys' fees, arising out of Raytheon's use and occupancy of the
     Overleased Premises prior to the Commencement Date of this Sublease. 
     Subtenant agrees to indemnify and hold Raytheon harmless from and against
     any and all claims, suits, damages, liabilities and expenses, including
     reasonable attorneys' fees, arising out of Subtenant's use and occupancy of
     the portions of Overleased Premises from and after the Commencement Date
     under this Sublease.

     To the extent that the Overlandlord is given rights to inspection of, or
     access to, the Sublease Premises or to make audits or obtain documents or
     information from Raytheon, as Lessee under the Overlease, Subtenant hereby
     grants all such rights to Overlandlord such that Overlandlord shall have
     the same rights to inspections, access, audits, documents and information
     from Subtenant.

5.   TERM; CONDITION OF SUBLEASE PREMISES.  

     (a)  The term of this Sublease shall begin upon the execution date hereof
     referenced in the preamble of this Sublease (the "COMMENCEMENT DATE"), and
     shall expire upon the first to occur of the termination of the Overlease
     (subject, however, to the second sentence of the fifth paragraph of Section
     4 hereof regarding purchase of the Overleased Premises by Raytheon) or
     (unless this Sublease is extended as hereinafter provided) 11:59 P.M. on
     July 10, 2002.  

     (b)  Subtenant understands that Raytheon has options under Section 1.04 of
     the Overlease to extend the term of the Overlease until July 10, 2007, and,
     again, to July 10, 2012, and, finally, to July 10, 2017; PROVIDED, HOWEVER,
     Raytheon shall have no obligation to extend the Overlease for any of such
     extension periods.  Should Raytheon elect to extend the term of the
     Overlease past July 10, 2002, and, thereafter, past July 10, 2007, and
     thereafter, past July 10, 2012, then, if Subtenant is not in default under
     this Sublease, Subtenant shall have the right to extend the term of this
     Sublease for the identical extended terms(s) of the Overlease.  As a
     condition precedent to Subtenant's right to so extend the term of this
     Sublease, Subtenant shall first give notice to Raytheon of Subtenant's
     election not more than nineteen (19) months nor less than thirteen (13)
     months prior to the expiration of the initial term or

<PAGE>

                                         -7-

     the current renewal term, as applicable.  After receipt of Subtenant's
     notice, Raytheon shall notify Subtenant as to whether or not Raytheon will
     be exercising the applicable renewal option under Section 1.04 of the
     Overlease.  Subject to adjustments of rent as described in Section 2.01 of
     the Overlease, such renewals of this Sublease shall be on the same terms,
     covenants and conditions provided for in this Sublease and the Overlease.

     (c)  Subtenant agrees to accept those portions of the Overleased Premises
     to be occupied by Subtenant (including any additional portions of the
     Overleased Premises taken by Subtenant following the execution date hereof)
     on an "as-is", "where-is" basis on the Commencement Date or such subsequent
     date for additional portions, and in substantially the same condition as
     said Overleased Premises now are, and Raytheon makes no representation or
     warranty with respect to the condition thereof except that the relevant
     portions of the Overleased Premises currently are in compliance with the
     Overlease and will be in compliance therewith on the Commencement Date.


6.   RENT.  During the term of this Sublease, Subtenant shall pay to Raytheon a
     monthly rental equal to the Applicable Percentage of the monthly charges
     paid by Raytheon under the Overlease for occupancy of the Overleased
     Premises, including, without limitation, the Applicable Percentage of all
     Base Rent, Additional Rent and Special Services Charges, Costs of Insurance
     (as defined in Section 9(a) below), increases in premiums and Taxes under
     Sections 2.01, 2.02, 9.04 and Article 14 of the Overlease and Section 9(a)
     of this Sublease, but excluding Utility Charges (as defined below) (which
     shall be calculated and paid in accordance with Section 8 below), which
     monthly rental shall be payable in advance by the first (1st) day of each
     calendar month during the term of this Sublease (or, with respect to the
     initial partial calendar month, on the date of this Sublease).  The
     Applicable Percentage is calculated by dividing the net square feet (the
     "NSF") of the Sublease Premises by 659,769 square feet, the NSF of the
     Overleased Premises.  As of the date of this Sublease, the Applicable
     Percentage, based on an initial Sublease Premises of 95,000 square feet, is
     14.4%.  

7.   PAYMENT OF RENT.  Payments of Rent shall be sent to the following address:

8.   UTILITY CHARGES; SPECIAL SERVICES.  For purposes of this Sublease, the
     following terms shall have the following meanings:

     (a)  "SUBTENANT'S UTILITIES" shall  mean the electricity, natural gas,
     water (city), sewer, and fire suppression water as Subtenant may reasonably
     require and request from time to time during the term of this Sublease for
     the conduct of its business and consistent with historical usage by
     Raytheon within the Sublease Premises; 

     (b)  "COST OF SUBTENANT'S UTILITIES" shall mean the sum of (x) the cost
     paid by Raytheon to a third party provider (including, without limitation,
     the Overlandlord) of the electricity, sewer, water (city) and natural gas
     utilities consumed as Subtenant's Utilities (including without limitation
     any such utilities consumed to provide the heating, ventilation and air
     conditioning and the fire suppression water consumed by Subtenant as a
     Subtenant Utility) plus (y) reasonable cost of delivery of Subtenant's
     Utilities incurred by Raytheon.

     (c)  "SPECIAL SERVICES" and "SPECIAL SERVICES CHARGES" shall mean those
     Special Services and Special Services Charges described in Section 3.02 of
     the Overlease; and

     (d)  "UTILITY CHARGES" shall mean the cost of Subtenant's Utilities and
     applicable sales taxes that are paid by Raytheon, whether Subtenant's
     Utilities are separately metered or equitably allocated.

     Except to the extent Utility Charges and/or Special Service Charges are
     directly invoiced to Subtenant by a third-party utility provider or by the
     Overlandlord or some

<PAGE>

                                         -9-

     other third party (in which case Subtenant shall promptly pay any amounts
     owed), Subtenant shall reimburse Raytheon for the Cost of Subtenant's
     Utilities and Special Services as metered (where separately metered) and as
     equitably allocated (where not metered), together with applicable sales
     taxes.  Subtenant shall cooperate with Raytheon in providing data on
     Subtenant's operations necessary to calculate such allocation.  Attached
     hereto as EXHIBIT E is a schedule setting forth the estimated monthly
     Utility Charges and Special Services Charges agreed between Raytheon and
     Subtenant.  Subtenant shall pay to Raytheon as Additional Rent, due upon
     execution of this Sublease and one (1) month in advance of the first day of
     every succeeding month, without notice, setoff, demand or deduction, an
     estimated amount for such Utility Charges and Special Services Charges
     which initially shall be $134,460 per month (until revised in accordance
     with EXHIBIT E and/or the immediately succeeding paragraph, as applicable),
     irrespective of the actual consumption period.

     On or before March 15, 1999 and each March 15th thereafter during the term
     of this Sublease, Raytheon shall reasonably estimate, and notify Subtenant
     of, the amount to be paid by Subtenant as Utility Charges for each month of
     the ensuing twelve month period, based on forecasts of the Cost of
     Subtenant's Utilities for that calendar year, if available, or the actual
     Cost of the Subtenant's Utilities during the previous calendar year.  Such
     estimated monthly amounts shall be due and payable to Raytheon one (1)
     month in advance on the first day of every month without setoff, demand or
     deduction, in lieu of the estimated monthly amount payable referred to in
     the immediately preceding paragraph.

     Commencing on June 15, 1998, and continuing quarterly on each September
     15th, December 15th, March 15th and June 15th thereafter, Raytheon shall
     determine and provide notice to the Subtenant of the actual Utility Charges
     payable by Subtenant for the previous three (3) calendar month period (or
     period from the date of this Sublease through May 31, 1998, in case of the
     initial notice).  If the estimated amount of Utility Charges paid by
     Subtenant for such period differs from the actual amount, then Subtenant
     shall pay to Raytheon any underpayment within thirty (30) days following
     receipt of such statement or Raytheon shall credit against the next rentals
     payable by Subtenant the amount of any overpayment as the case may require;
     provided, however, that if this Sublease has terminated or expired, any
     overpayments shall be remitted to Subtenant by Raytheon together with
     Raytheon's reconciliation notice.  The obligations under this Section 8
     shall survive termination, expiration or abandonment of this Sublease.

     Subtenant shall make arrangements for Subtenant's telephone requirements
     and shall timely pay all charges in connection with Subtenant's telephone
     usage and needs.

13.  BROKER.  Each of Subtenant and Raytheon represents and warrants to the
     other party that it has not directly or indirectly dealt, with respect to

14.  ASSIGNMENT; SUBLEASES; MORTGAGES; AND ENCUMBRANCES.  Subtenant shall not
     assign this Sublease, sublet, license, mortgage or otherwise encumber the
     Sublease Premises, or any part thereof, without the prior written consent

16.  EARLY TERMINATION RIGHTS OF SUBLEASE.  None.

17.  EXCAVATION RESTRICTION.  Subtenant shall not do any of the following (an
     "EXCAVATION") at the Sublease Premises without the prior written consent of
     each of Raytheon and the Overlandlord: (i) intentionally penetrate the
     soil; (ii) excavate, dig into or remove the soil; (iii) take any samples of
     soil or groundwater; (iv) drill any holes into soil or the floor of any
     building or pavement covering the soil; or (v) remove any part of any
     building or pavement directly covering the soil.  In the event that
     Subtenant is required to undertake any Excavation as a consequence of any
     local, state or federal law, rule, ordinance, code, requirement, statute,
     regulation or any order, injunction, decree or ruling issued by a court of
     competent jurisdiction or any other governmental entity applicable to the
     Sublease Premises or Subtenant's operations thereon (a "REQUIRED
     EXCAVATION"), Subtenant shall promptly notify Raytheon and Overlandlord in
     writing, describing in reasonable detail the nature and purpose of such
     Required Excavation.  Raytheon shall not unreasonably withhold its consent
     to any Required Excavation, and Raytheon shall reasonably cooperate with
     Subtenant in obtaining the consent of the Overlandlord to any Required
     Excavation, provided that (i) Raytheon may elect to undertake to perform
     such Required Excavation at its own cost, (ii) Raytheon may delay
     performance of the Required Excavation and contest such obligation to
     perform (or have a third party contest such obligation), so long as such
     contest is not reasonably likely to (x) result in a material adverse effect
     to Subtenant or a material disruption of the operations of Subtenant at the
     Sublease Premises or (y) subject Subtenant to criminal liability and (iii)
     Raytheon shall have no liability if the Overlandlord fails to consent to
     any Required Excavation.

          In addition to the foregoing, TI may from time to time adopt other
rules or regulations generally applying to occupants, including tenants, of the

responsibilities with respect to environmental matters as set forth herein,
Lessee further agrees to comply with all applicable City, County, State and
Federal laws and regulations, including, without limitation, building codes,
electrical codes and fire codes which now are or hereafter become applicable to
the Leased Premises and, to the extent made necessary in connection with
Lessee's use of the Leased Premises, to any other portion of the TI Expressway
Site.

          Nothing contained in this Lease, however, shall be construed to
prevent Lessee from adopting or otherwise implementing standards or policies
with respect to Lessee's occupancy, use or operations on the Leased Premises
that are more stringent than required by applicable laws and regulations.

     Subject to Article 25, and except as otherwise provided herein, Lessee
shall have quiet and peaceful enjoyment of the Leased Premises during the Lease

     SECTION 1.04.  RENEWAL OPTION.

     While this Lease is in full force and effect, provided that there is no
uncured material default beyond expiration of any applicable grace or cure
period by Lessee of any of the terms, covenants, and conditions hereof, Lessee
shall have three (3) separate options to extend the term of this Lease for the
further term of sixty (60) months each (each such term being referred to herein
as a "Renewal Term").  Except as specifically stated elsewhere in this Lease,
and subject to adjustment of rent as described in Section 2.01 below, such
renewals shall be on the same terms, covenants, and conditions as provided for
in this Lease.  Notice of Lessee's intention to exercise its option to renew
this Lease as permitted by this Section 1.04 (the "Renewal Notice") must be
given to Lessor not less than twelve (12) nor more than eighteen (18) months

     SECTION 1.05.  TRANSITION ACTIVITIES.

     Lessor and Lessee acknowledge that certain relocations, consolidation,
construction, and modifications to the Leased Premises, TI Expressway Site
and/or other premises owned or operated by Lessor or Lessee and related
activities (the "Transition Activities") are necessary and will occur following
commencement of the Primary Term to accommodate certain requirements and
expectations of Lessee and Lessor.  Such Transition Activities shall be
implemented by Lessor and conducted in accordance with the mutual agreement of
the parties acting in good faith.  The period during which Transition Activities
are occurring that affect the final configuration of the Leased Premises is
referred to herein as the "North Building Transition Period."


                                      ARTICLE 2
                                        RENTAL

     SECTION 2.01.  BASE RENT.

     Lessee shall pay Base Rent to Lessor in advance on the Commencement Date
and on the first day of each month thereafter, without (subject to Article 34,
below) setoff, demand, or deduction during the Lease Term.  During the first
year of the Primary Term of this Lease, the Base Rent shall be Three Million One
Hundred Seventy-Five Thousand and No/100 Dollars ($3,175,000.00) per annum,
payable in equal monthly installments of Two Hundred Sixty-Four Thousand Five
Hundred Eighty-Three and No/100 Dollars ($264,583.00) per month.  During the
Primary Term, Base Rent shall be adjusted annually on each anniversary of the
Commencement Date, so that Base Rent payable during the Primary Term shall be
paid as follows:

         Lease Period         Annual Rent         Monthly Rent
         ------------         -----------         ------------
           1st Year          $   3,175,000.      $     264,585
           2nd Year          $   5,728,000.      $     477,333
           3rd Year          $   9,341,000.      $     778,417
           4th Year          $  12,954,000.      $   1,079,500
           5th Year          $  12,954,000.      $   1,079,500

     Payment shall be made in accordance with Section 2.04 below.  Base Rent
shall include the Basic Services set forth in Section 3.01. below.

     Base Rent shall be subject to adjustment at the commencement of each
Renewal Term (in each case, "Adjustment Date") as follows:

     (a)  The base for computing the adjustment is the Consumer Price Index,
published bimonthly by the United States Department of Labor, Bureau of Labor
Statistics ("BLS") in CPI DETAILED REPORT, Consumer Price Index All Urban
Consumers (CPI-U): Selected Areas, All Items Index (Dallas/Fort Worth)
(1982-1984=100) ("Index").  The number indicated in the Index for the


                                         -4-
<PAGE>

month and the year in which the Commencement Date occurs shall be the "Base
Index."  The number in the Index for the month and the year which is 45 days
prior to the month and the year in which the rent adjustment occurs shall be the
"Current Index."  The Current Index shall take into consideration any changes
arising from the BLS publishing data on a base period other than 1982-1984=100.

     (b)  Except as set forth in clause (c) below, forty-five (45) days prior to
each Adjustment Date, if the Current Index has increased over the Base Index,
the Base Rent for the Renewal Term (until the next rent adjustment) shall be set
by multiplying the Base Rent for the fifth year of the Primary Term by a
fraction, the numerator of which is the Current Index and the denominator of
which is the Base Index.  If the Current Index has decreased from the Index
employed at the previous Adjustment Date, the Base Rent for the Renewal Term
(until the next rent adjustment) shall be set by multiplying the Base Rent for
the fifth year of the Primary Term by a faction, the numerator of which is the
Current Index and the denominator of which is the Base Index, such that the Base
Rent for the Renewal Term shall be less than the Base Rent for the previous
term.  Provided however, that in no case shall the Base Rent be less than the
Base Rent for the fifth year of the Primary Term.  The new Base Rent shall take
effect on the Adjustment Date and Tenant shall be provided with written notice
of such new Base Rent thirty (30) days prior to the Adjustment Date.

     (c)  If, forty-five (45) days prior to the Adjustment Date, the Current
Index for such date is not yet available, Lessee shall pay Lessor the Base Rent
for the Primary Term as it may have been previously increased or decreased,
until such Current Index is published and available, at which time Lessee shall
pay Lessor the increase, if any, retroactively from the applicable Adjustment
Date.

     (d)  If the index is discontinued or revised during the Lease Term, such
other government index or computation with which it is replaced shall be used in
order to obtain substantially the same result as would be obtained if the index
had not been discontinued or revised.

     SECTION 2.02.    ADDITIONAL RENT AND SPECIAL SERVICES CHARGES.

     As additional rent ("Additional Rent"), which shall also be due on a
monthly basis and payable in accordance with Section 2.04, Lessee shall pay to
Lessor all other amounts that Lessee is obligated to pay under the terms of this
Lease, including, without limitation, Special Services Charges for Special
Services described in Section 3.02 below and requested by Lessee.

     SECTION 2.03.    UTILITY CHARGES.

     For the purpose of this Lease, the following terms shall have the following
meanings:

     (a)  "Lessee's Utilities" shall mean the electricity, natural gas, water
(city), sewer, and fire suppression water as Lessee may reasonably require and
request from time to time during the Lease Term for the conduct of its business
and consistent with historical usage by the Defense Business within the Leased
Premises; and



                                         -5-
<PAGE>

     (b)  "Cost of Lessee's Utilities" shall mean the sum of (X) the cost paid
by Lessor to a third party provider of the electricity, sewer, water (city) and
natural gas utilities consumed as Lessee's Utilities (including without
limitation any such utilities consumed to provide the heating, ventilation and
air conditioning and the fire suppression water consumed by Lessee as a Lessee's
Utility) plus (Y) reasonable cost of delivery of Lessee's Utilities incurred by
Lessor.

     Except to the extent Utility Charges (as defined below) are directly
invoiced to Lessee by a third-party utility provider (in which case Lessee shall
promptly pay any amounts owed), Lessee shall reimburse Lessor for the Cost of
Lessee's Utilities as metered (where separately metered) and as equitably
allocated (where not metered), together with applicable sales taxes (the
"Utility Charges").  Lessee shall pay to Lessor as Additional Rent, due one (1)
month in advance on the first day of every month, without setoff, demand or
deduction, an estimated amount for such Utility Charges which initially shall be
Three Hundred Forty Thousand Five Hundred and No/100 Dollars ($340,500) per
month, irrespective of the actual consumption period, based on Lessor's Annual
Utility Plan for 1997, if available, or the actual cost of the Lessee's
Utilities for calendar year 1996.

     On or before February 15, 1998 and each February 15 thereafter during the
Lease Term, Lessor shall reasonably estimate, and notify Lessee of, the amount
to be paid by Lessee as Utility Charges for each month of the ensuing twelve
month period, based on forecasts of the cost of Lessor's Utilities for that
calendar year, if available, or the actual cost of the Lessee's Utilities during
the previous calendar year.  Such estimated monthly amounts shall also be due
and payable to Lessor one (1) month in advance on the first day of every month
without setoff, demand or deduction.

     Commencing on the first such date to occur after a period of three (3) full
calendar months after the expiration of the North Building Transition Period and
continuing quarterly on each February 15, May 15, August 15, and November 15,
Lessor shall determine and provide notice to Lessee of the actual Utility
Charges payable by Lessee for the previous three (3) calendar month period.  If
the estimated amount of Utility Charges paid by Lessee for such three (3) month
period differs from the actual amount, then Lessee shall pay to Lessor any
underpayment within thirty (30) days following receipt of such statement or
Lessor shall credit against the next rentals payable by Lessee the amount of any
overpayment as the case may require; provided, however, that if this Lease has
terminated or expired, any overpayment shall be remitted to Lessee by Lessor
together with the Lessor's reconciliation notice.  The obligations under this
Section 2.03 shall survive termination, expiration or abandonment of this Lease.

     SECTION 2.04.    PAYMENT OF RENT.

     Lessee shall pay Base Rent and Additional Rent (sometimes collectively
referred to herein as "Rent"), in U.S. dollars or other currency that, at the
time of the payment, is lawful money of, and legal tender for debts in, the
United States of America.  Payments of Base Rent and Additional Rent for any
partial months shall be prorated based on a 365 day year.  Payments of Rent
shall be sent to the following address:

                                SERVICE AND FACILITIES

     SECTION 3.01.    SERVICES PROVIDED BY LESSOR.

     At all times during the Lease Term, Lessor shall provide or cause to be
provided to Lessee at the Leased Premises as appropriate, the following services
("Basic Services") as an incident to this Lease (the charges for these services
are included in Base Rent):

          (1)  Lessor shall maintain the roof and structural elements of the
               Leased Premises in good operable condition and repair, reasonable
               wear and tear excepted, including, without limitation, the making
               of any capital repairs or capital


                                         -7-
<PAGE>

               improvements required to comply, in all material respects, with
               any law, building code, rule, regulation, judicial mandate, or
               other governmental requirement, excluding, however, (i) any
               maintenance requirements necessitated by Alterations (as defined
               below) made by Lessee, and (ii) requirements to be performed by
               Lessee under Section 17b, below.

          (2)  Lessor shall maintain the grounds of the TI Expressway Site in
               good condition and repair, including without limitation:

               (A)    maintenance of parking lots, roads, building grounds,
                      outside lighting, underground utility lines for
                      electricity, water, storm and other sewers, cooling and
                      heating water, fire protection sprinklers and piping, and
                      other utilities serving the areas of the TI Expressway
                      Site outside of the Leased Premises.

               (B)    clearing of ice and snow from sidewalks; and

               (C)    landscaping, including replacement and trimming of plants
                      outside the Leased Premises.

          The services provided hereunder shall be available during the hours

Site.  All such services shall be provided by personnel designated in the sole
discretion of Lessor.

          Subject to Articles 21 and 35, this Lease has been entered into by
Lessor and Lessee with the understanding that Lessee's Utilities will be
available for consumption and use in the Leased Premises during the Leased Term
at volumes and pressures of such utilities historically consumed and used by the
Defense Business operations being conducted in the Leased Premises as if the
Defense Business had been conducted in the entire Leased Premises.  Lessor
agrees that it will take no actions which will materially and adversely affect
the volume, pressure, and availability of the Lessee's Utilities, without the
prior consent of Lessee.  Subject to the foregoing sentence, in no event shall
Lessor be liable for any failure of a gas, electricity, water, telephone, sewer
utility or other utility to provide a sufficient, uninterrupted quantity of
water, electricity, gas, telephone or sewer or other utility service to the
Leased Premises, except to the extent (a) such failure results from Lessor's
non-payments to the supplier (unless such non-payment results from Lessee's
failure to reimburse Lessor for such utility service as required by this Lease),
or (b) Lessor's failure to maintain orders/contracts with a supplier for
delivery of such utility as previously consumed and used by the Defense Business
operations being conducted in the Leased Premises.  Lessor will reasonably
cooperate with Lessee to pass through to Lessee any rights Lessor may have
against any provider of such utilities in the event of any interruption or
failure of services by such utility provider.

reasonably required to provide vehicular and pedestrian access to the Leased
Premises, and as reasonably necessary for the business operations conducted by
Lessee on the Leased Premises.  Further, in the event of any internal or
external union organizing activity involving Lessee's employees, Lessor shall be
entitled to reasonably restrict or prevent access by any of Lessee's employees
involved in such union organizing activity to portions of the TI Expressway Site
other than the Leased Premises, and as otherwise necessary to prevent
disturbance of Lessor's operations on the TI Expressway Site.  In the event of
any internal or external union organizing activities involving Lessor's
employees, Lessor shall, to the extent allowed by law, reasonably restrict or

                                      ARTICLE 5
                        LESSEE'S ALTERATIONS AND IMPROVEMENTS

     Material Changes to the Leased Premises shall require the prior consent of
Lessor, which consent shall not be unreasonably withheld.  As used herein,
Material Change shall mean any addition, alteration, or improvement including
installation or modification of equipment (hereinafter, "Alteration"), where
such Alteration involves connections to any Lessee's Utility Systems (defined as
the Lessor-owned or controlled lines, pumps, equipment and facilities which
deliver, provide and/or produce the Lessee's Utilities) or to the building-wide
plumbed process gas distribution system including, without limitation: fire
suppression systems; structural modifications (including any penetrations of the
floor, roof or outside walls); electrical, gas, water, sewer, or exhaust
distribution systems; any control systems monitored or maintained by Lessor; any
tele/data communications systems maintained by Lessor, and where such Alteration
or any process change has or could reasonably be expected to have a material
adverse effect on the Lessee's Utility Systems, building-wide plumbed process
gas distribution system or the structural integrity of the Leased Premises or
any other portion of the TI Expressway Site.

     Lessor shall review and respond to Lessee within fifteen (15) days from
Lessor's receipt of Lessee's notice of Lessee's intent to make any Alteration
which Lessee reasonably believes could constitute a Material Change.  If Lessor
fails to respond to Lessee within said fifteen (15) day period,


                                         -10-
<PAGE>

Lessor shall be deemed to have approved the proposed Alteration.  Any notices
made pursuant to this Article will describe the nature of the Alteration and
will include the estimated date and time at which Lessee proposes to commence
such Alteration.  In the event Lessee uses a contractor to make any Material
Change, Lessee shall use a contractor (i) that carries at least One Million
Dollars ($1,000,000) of general liability insurance and all workers'
compensation and employers liability insurance required by applicable law with
respect to the workers on the TI Expressway Site or that is otherwise insured to
Lessor's satisfaction and whose subcontractors are likewise insured, and
(ii) has been approved in advance by Lessor's Facilities Manager for the TI
Expressway Site or his designee, said approval not to be unreasonably withheld
or delayed: provided, however, any connections to Lessee's Utility Systems or to
the building-wide plumbed process gas distribution system shall be performed at
Lessee's cost by or under the direction of TI, which shall commence and complete
such activity requested by Lessee in a timely and diligent manner.  Lessor, in
its discretion, may require Lessee's contractors and their subcontractors to be
bonded for projects having an estimated cost in excess of $250,000.00 by a bond
reasonably satisfactory to Lessor.

     All Alterations, including Material Changes, shall comply with all
applicable laws, regulations, building, electrical and fire codes, as well as
with the requirements of any casualty insurer of the TI Expressway Site.

     Upon the request of Lessee, Lessor shall advise Lessee within sixty (60)
days whether it reserves the right to require Lessee to remove any Alterations
from the Leased Premises upon termination of the Lease.  If Lessee so requests
and Lessor does not so reserve the right to require Lessee to remove any
Alterations present at the time of request from the Leased Premises, Lessor may
not require Lessee to remove such Alterations from the Leased Premises upon the
expiration or sooner termination of the Lease.

     Subject to any abandonment as described in Article 23 below, all
Alterations, trade fixtures, equipment, and personal property (i) installed in
the Leased Premises after the Commencement Date at Lessee's expense, excluding,
unless otherwise agreed by Lessor and Lessee, Alterations, trade fixtures,
equipment, and personal property installed as part of the Transition Activities,
or (ii) located in the Leased Premises on the Commencement Date and owned by
Lessee ("Lessee's Property") shall at all times remain Lessee's property and
Lessee shall be entitled to all depreciation, amortization and other tax
benefits with respect thereto.  Except for Alterations which cannot be removed
without structural injury to the Leased Premises, at any time Lessee may remove
Lessee's Property from the Leased Premises, provided Lessee repairs at its
expense all damage caused by such removal.

     Lessee shall pay for any and all such Alterations and any costs incurred in
connection therewith, including, with respect to any services provided by Lessor
as a Special Service, reimbursement of Lessor's cost as a Special Service
charge.  To the extent Lessee manages the Alteration, Lessee will obtain waivers
of all mechanic's liens which may arise as a result of such Alteration,
provided, however, if Lessee is unable to obtain any such waiver after the use
of its reasonable efforts, Lessees shall indemnify, defend, and hold harmless
Lessor from any reasonable actual cost or damage with respect to the existence
of any such mechanic's lien and shall take all necessary legal actions,
including the posting of any sums at issue with a court of competent


                                         -11-
<PAGE>

jurisdiction to clear the lien within thirty (30) days after Lessee becomes
aware that the lien has been filed.  To the extent Lessee requests and Lessor
agrees to manage the Alteration.  Lessor will obtain waivers of all mechanic's
liens which may arise as a result of such Alteration.  Provided, however, if
Lessor is unable to obtain any such waiver after the use of its reasonable
efforts, Lessor shall take all necessary legal actions, including the posting of
any sums at issue with a court of competent jurisdiction to clear the lien
within sixty (60) days after Lessor receives notice from Lessee that the lien
has been filed, except to the extent resulting from Lessee's failure to pay the
charges for the services performed that Lessee is responsible for hereunder
within thirty (30) days following delivery to Lessee of notice and demand,
either to the contractor or supplier or to Lessor.

                  ASSIGNMENTS; SUBLEASES; MORTAGES; AND ENCUMBRANCES

encumber the Leased Premises, or any part thereof, without the prior written

therefrom through a public exchange or as part of any institutional or publicly
offered financing, shall be deemed to be (i) an assignment or in any manner a
transfer of the Lease or any estate or interest therein, (ii) a sublease of
Lessee's interest in the Leased Premises, or any part thereof, (iii) a change in
control of ownership of Lessee or (iv) a breach of default under the Lease or an
event which, with the passage of time, the giving of notice, or both, would
constitute a breach of default under the Lease.  With the prior consent of
Lessor, which consent shall not be unreasonably wihheld, Lesee may assign this
Lease or sublease the Leased Premises, or any portions thereof to any
subsidiary, affiliate, or division of Lessee, except that assignment to any
subsidiary, affiliate or division of Lesee as may exist as of the Commencement
Date shall not require Lessor's consent.  Any purported assignment, sublease,
license, mortgage or other encumbrance entered into by Lessee shall not relieve
Leseee of its obligations under this Lease and, if not in compliance with this
Article 6, shall be void AB INITIO.

cooperate to place and maintain labels on the lines and distribution systems
described in this paragraph to delineate maintenance responsibility.

     Nothwithstanding anything herein to the contrary, to the extent that any
utility lines, pipes, or other conduits for assisting in the site-wide
distribution systems for the TI Expressway Site go through the Leased Premises,
Lessee shall have no liability or obligation for maintenance or repair of such
utility lines, or conduits, except for laterals of such lines, pipes, or
conduits which in fact serve the Leased Premises.

     Lessee shall maintain in good operable condition and repair, reasonable
wear and tear excepted, all mechanical, electrical, heating, ventilation and air
conditioing, power, plumbing, sewer, water (city), industrial waste water, gas,

responsibility for repairs occasioned by damage to Lessor's equipment and
systems resulting directly or indirectly from any acts or omissions of Lessee.

replacement or removal of any of Lessee's equipment in the Leased Premises.

forty-five (45) days after such fire or casualty.

Article 10, this Lease shall terminate as of the date of Lessee's surrender of
the Leased Premises, which shall occur within a reasonable time, which will not
be longer than ninety (90) days after the date of the termination notice.

this Lease pursuant to this Article 10, as of the date of such termination, the
term of this Lease shall expire as completely and as fully as if such date were

Lessor and Lessee agree to reasonably cooperate to enable repair and restoration
to be undertaken as soon as practical.

     If all or greater than sixty percent (60%) of the Leased Premises shall be
taken under the power of eminent domain by any competent governmental authority,
this Lease shall terminate as of the date of such taking as if such date were
the date set forth above for the termination of the then current term of the
Lease.  If sixty percent (60%) or less of the Leased Premises shall be taken
under such power of eminent domain, as of the date of such taking, the Rent
shall be equitably reduced.  Notwithstanding the foregoing and in any event,
should any taking materially interfere with Lessee's ability to use the Leased
Premises for their intended purposes, Lessee may, in its reasonable discretion,
by notice to Lessor, elect to terminate this Lease as set forth herein.  The
Rent shall be pro-rated or reduced as of the date of any such taking.  In any
condemnation proceeding, Lessor and Lessee shall each be entitled to bring suit

and all claims or proceedings made or brought (whether brought by an employee or
other private party or governmental agency) for bodily injury, property
impairment or any other injury or damage resulting from or relating to, and/or
any legally imposed requirements for the monitoring, remediation, investigation
or removal of any hazardous, toxic or radioactive substance, contaminated
material, or air contaminant located upon or migrating into, from or through the
TI Expressway Site to the extent caused by the acts or omissions of Lessor, its
employees, contractors, agents, officers or directors, whether or not the
alleged liability is attributable to the handling, storage, generation,
transportation or disposal of such substance or the mere presence of the
substance on the TI Expressway Site; including claims based on strict liability.
In the event any loss or damage is attributable to both Lessor and Lessee,
Lessor agrees, without regard to any concurrent or other negligence by Lessee
(if any), to provide Lessee with comparative indemnification for that portion of
the loss or damage which is attributable to Lessor and/or Lessor's officers,
directors, employees, contractors, agents or visitors, excluding any portion of
such loss or damage attributable to the operations of the Defense Business which
are Assumed Liabilities on or prior to the Commencement Date, irrespective of
either Party's negligence.  Notwithstanding anything to the contrary in this
Lease, Lessor's obligations under this Article 12 shall survive termination,
expiration or abandonment of this Lease.  As used herein, "TI Space" shall mean
any portion of the TI Expressway Site which is not (i) part of the Leased
Premises or (ii) otherwise leased by Lessee at the time of such event or
activity.

                          EMERGENCIES/REPORTING OBLIGATIONS

     SECTION 13.01.  REPORTING TO LESSOR.

     In the event of emergency situations of which Lessee is aware (including,
without limitation, fires, accidental chemical spills or exposures, unauthorized
air emissions, unauthorized radiation emissions or exposures, unauthorized
discharges into waste streams, or other environmental, industrial hygiene or
safety emergencies), Lessee shall immediately report such occurrence to Lessor.

     SECTION 13.02.  REPORTING TO GOVERNMENTAL AGENCIES.

     With respect to Lessee's use of the Leased Premises during the Lease Term,
Lessee shall be solely responsible for compliance with all governmental
reporting duties imposed upon Lessee by applicable laws, and (in addition to
reporting to Lessor as provided in the preceding paragraph) Lessee shall report
any emergency situation to the applicable governmental agency (if any) to the
extent required by, and within the time periods prescribed by, applicable laws. 
In the event Lessee fails to comply with its statutory or contractual duty to
report such emergency situations to any governmental agency, Lessor may, but
shall not be obligated to, upon learning of such failure, report such matters. 
The parties shall coordinate in an effort to avoid duplicate reporting of any
emergency situation.  Under no circumstances, however, shall this provision be
construed to be an assumption by Lessor of any reporting duty on behalf of
Lessee.

                                        TAXES

     Ad valorem taxes for the Leased Premises will be charged by Lessor to
Lessee during the Lease Term, and Lessee shall pay and discharge as Additional
Rent such ad valorem taxes for the North Building, based on Lessee's
proportionate share thereof, which shall be that percentage derived by dividing
(1) the NSF of the Leased Premises in the building (exclusive of the Exterior
Equipment Locations), by (2) the total of (a) the NSF of the Leased Premises in
the building (exclusive of the Exterior Equipment Locations), and (b) the NSF of
any TI space, if any, in the building (i.e. any net square footage in the
building that is not included in the Leased Premises).  Ad valorem taxes for the
North Building will be determined based on the North Building's pro rata share
of TI Expressway Site site-wide taxes, calculated on the basis of net book
value, as reflected in the records maintained by Lessor's Corporate Services
Finance Department prepared in accordance with disclosure statement approved by
the Defense Logistics Agency/DCAA or with generally accepted accounting
principles.  Such taxes shall be due and payable fifteen (15) days after notice
from Lessor.  Lessor and Lessee shall reasonably cooperate regarding ad valorem
tax issues, and avoid actions which would result in unfair discrimination with
regard to allocation or distribution of ad valorem taxes or the property
assessments on which such taxes are based.


                                         -22-
<PAGE>

     Except for ad valorem taxes assessed directly on the TI Expressway Site,
all taxes and assessments now or hereinafter imposed upon Lessee with respect to
its operations or property, now or hereinafter imposed, shall be borne and
timely paid directly by Lessee to the taxing authority.

                 NO JOINT VENTURE, PARTNERSHIP, OR AGENT RELATIONSHIP

     The relationship between Lessor and Lessee, with regard to this Lease, is
strictly that of lessor/lessee and contracting parties; Lessor and Lessee are
not partners, joint venturers or agents of each other.

     Additionally, notwithstanding any services or assistance provided by Lessor
or Lessee to the other hereunder or under any other agreement;

     (a)  Neither party shall be responsible, either directly or indirectly,
expressly or impliedly, for compliance with any laws applicable to the other's
particular use of the TI Expressway Site;

     (b)  Lessee shall be solely responsible for its compliance with
environmental, health, and safety laws and regulations relating to Lessee's
operations in or about the Leased Premises, and Lessee shall prepare or cause to
be prepared all documentation and make all arrangements for disposal or other
handling of its hazardous waste, potentially recyclable hazardous materials, and
any other waste generated by Lessee or its agents or contractors requiring
manifests under applicable law;

     (c)  Lessee shall not be responsible, either directly or indirectly,
expressly or impliedly, for Lessor's compliance with any laws, regulations,
ordinances, permits, or licenses applicable to Lessor's use of the TI Expressway
Site; and

     (d)  Lessor shall be solely responsible for its compliance with
environmental, health, and safety laws and regulations relating to Lessor's
operations in or about the TI Space, and Lessor shall prepare or cause to be
prepared all documentation and make all arrangements for disposal or other
handling of its hazardous waste, potentially recyclable hazardous materials, and
any other waste generated by Lessor or its agents or contractors requiring
manifests under applicable law.

           LESSEE'S ENVIRONMENTAL, INDUSTRIAL HYGIENE AND SAFETY COVENANTS,
                            REPRESENTATIONS AND WARRANTIES

     In addition to the other provisions of this Lease, Lessee covenants,
represents and warrants that, during the term of this Lease and so long as
Lessee or any of Lessee's employees, contractors, agents or visitors are located
in the Leased Premises or are on the TI Expressway Site, Lessee shall comply
with the following:

     (a)  Lessee shall not violate, and Lessee shall not take any action that
would cause Lessor to be out of compliance with, any environmental, safety, or
industrial hygiene law (including, without limitation, principles of common law)
or any applicable permit, license, or authorization; Lessee shall comply with
each and every environmental permit issued to Lessee with respect to its use of
the Leased Premises as a result of Lessee's use or occupancy of the Leased
Premises, whether any such permit is issued in the name of Lessor, Lessee or any
third party; Lessee shall be responsible for obtaining and maintaining any and
all permits, licenses, authorizations, approvals, and exemptions as required for
Lessee's operations on the Leased Premises or Lessee's use of the TI Expressway
Site under this Lease under applicable environmental, safety, and industrial
hygiene laws, and Lessee shall pay for all fees and costs associated with
environmental permit applications, permit amendments, modifications or
revisions, registrations, governmental assessments or other governmental charges
of every type whatsoever relating to Lessee's operations on the Leased Premises
or its use of the TI Expressway Site under this Lease.  The parties acknowledge
and agree that because of the nature and configuration of the TI Expressway
Site, (1) Lessor and Lessee shall petition the Texas Natural Resource
Conservation Commission (TNRCC) to designate the Leased Premises and the balance
of the TI Expressway Site as a single property for purposes of evaluating air
quality impacts pursuant to 30 Texas Administrative Code Section 101.2(b) and
shall enter into a single property designation agreement effective as of the
Commencement Date substantially in the form attached as Exhibit "B" hereto and
made a part hereof; and (2) during the North Building Transition Period, Lessor
and Lessee may both discharge under Lessor's waste water permit from the City of
Dallas, Permit No. 040224, together with any renewals, reissuances, or
modifications thereof (the "TI Waste Water Permit"), a copy of which has been
provided by Lessor to Lessee, provided, however, Lessee shall be responsible for
ensuring that its discharges comply with the terms of such permit, provided,
however, either prior to or during the North Building Transition Period, Lessee
shall apply for and diligently pursue issuance of a separate waste water
discharge permit covering its waste water discharges from the TI Expressway Site
(prior to the point such discharges commingle with those of Lessor).  Upon
issuance of such separate permit, Lessee's waste water discharges at the TI
Expressway Site, including those from the North Building, will be governed by
such permit up to the point they commingle with the waste water discharges of
TI, from which point to combined outfall CWTP-16 they will be covered by the TI
Waste Water Permit.  At Lessor's request, Lessee agrees at its cost to sample
Lessee's waste water sampling ports concurrently with Lessor's sampling of its
waste water sampling ports.

     (b)  Lessee shall comply with all applicable federal, state and local laws
and lawful orders of any governmental entity, public authority or judicial
authority applicable to its use of the Leased


                                         -24-
<PAGE>

Premises and Lessee's operations thereon, including, without limitation, any
notice, reporting, and record keeping obligations imposed by any of the
foregoing.  Without limiting the generality of the foregoing, Lessee
acknowledges it shall comply with all reporting obligations under laws relating
to the health or safety of persons or property or their protection from damage,
injury or loss, and with the requirements of the Americans with Disabilities Act
and Texas Architectural Barriers Act to the extent such requirements first
become applicable as a result of Lessee's Alterations, repairs or improvements
or Lessee's specific use of the Leased Premises.

     (c)  Lessee shall designate a responsible member of its organization at the
Leased Premises, to function as the liaison between Lessor and Lessee in the
event either party deems it necessary to contact the other for purposes of
environmental, safety or industrial hygiene matters.

     (d)  Lessee shall exercise at least the level of care and skill customary
in its industry, and conduct all dangerous activities on the Leased Premises
under the supervision of properly qualified personnel; any hazardous, toxic or
radioactive materials, substances or wastes will be properly containerized,
labeled and stored; Material Safety Data Sheets, as defined in 29 C.F.R. Section
1910.1200 or any successor regulation, will be properly kept by Lessee and
furnished to the TI Facilities Coordinator.  Hazardous materials will not be
stored in stairwells, along emergency egress routes, near air handlers or
systems or otherwise in a manner that poses a hazard; gas cylinders will be
secured at all times.

     (e)  Lessee shall obtain its own EPA and TNRCC Identification Numbers,
arrange for disposal, and be identified on manifests as the generator, of all
hazardous or other waste generated from or otherwise arising out of Lessee's
operations on the Leased Premises.

     (f)  Lessee shall comply with all hazardous, toxic and radioactive waste
and materials handling and storage requirements under applicable laws,
regulations, ordinances and permits, and will exercise the utmost care when
handling and transporting such materials across the TI Space to which Lessee may
have access in the buildings in which the Leased Premises are located, and
across the TI Expressway Site.

     (g)  All hazardous, toxic or radioactive materials or substances delivered
or brought to the TI Expressway Site by Lessee, its employees, contractors, or
suppliers, will be received at a dock authorized to receive such materials.  All
docks which receive such materials shall have the following spill control
measures:  areas are to be sized for a free liquid volume capacity the greater
of 1.0 x the largest tank volume involved, or ten percent (10%) of the volume of
all tanks involved, or two percent (2%) of the total volume stored in drums,
carboys, or smaller containers at the location.  Spill control secondary
containment structures must be free of cracks and impermeable to leakage or
migration of any spills to the ground or support foundation.

     (h)  Lessee shall ensure that all emergency exits, fire extinguishers,
electrical panels and equipment, aisles and passageways will be accessible and
kept clear at all times and maintained in compliance with applicable OSHA
requirements; Lessee shall apply good housekeeping practices throughout the
Leased Premises.

     (i)  Lessee shall not make any changes in the character of (including
specific specification changes) or increase the volume of its actual air
emissions, other than de minimis increases, without the prior approval of TI. 
In the event such approval is received, prior to applying for any air permit
amendment and during the application process, Lessee shall coordinate with the
TI Expressway Site Environmental Manager or his or her designee in determining
anticipated impacts of the requested changes.

     (j)  Lessee shall implement best management practices and, to the extent
applicable, adhere to the other requirements of the storm water general permit
promulgated by EPA pursuant to 40 C.F.R. Section 122.28(c) and covering storm
water discharges at the TI Expressway Site.

     (k)  Lessee shall retain one or more Laser and Radiation Safety Officers,
trained and licensed to the extent required by applicable laws, to oversee and
ensure compliance with all radiation requirements applicable to the Leased
Premises.

     Any action based upon any breach of the foregoing representations,
warranties or covenants by Lessee, its agents, employees, contractors, tenants
and assigns, shall survive termination, abandonment, or expiration of this
Lease.


                                      ARTICLE 18
                                      DISCLAIMER

     Except as expressly set forth in this Lease, neither Lessee nor Lessor
makes any warranties, express or implied or otherwise, with respect to this
Lease; and subject to the terms of this Lease, Lessee acknowledges and agrees
that this Lease is made on an "as is" and "where is" basis.  Lessee further
acknowledges that Lessor makes no implied covenants with respect to this Lease. 
Without limiting the generality of the foregoing, no receipt, review, consent,
approval, acquiescence or other knowledge of a party of, in or to any plans,
specifications, additions, alterations, improvements, equipment or process
changes proposed or taken by Lessee or Lessor shall be deemed, or in any way
construed, to be any representation, warranty or guaranty with respect to such
plan, specification, addition, alteration, improvement, equipment or process
change and shall not relieve the other party of any responsibility or liability
therefor.


                                      ARTICLE 19
                                LESSOR'S AUDIT RIGHTS

     Upon not less than forty-eight (48) hours prior notice to Lessee, Lessor,
at its sole cost, may, but shall not be obligated to, enter the Leased Premises
and inspect Lessee's environmental records and operations, and sample/monitor
Lessee's waste streams, radiation and air emissions, for the sole purpose of
determining whether Lessee is in compliance with this Lease, provided that any
entry shall minimize to the extent reasonably possible any interference with the
business or operations conducted in the Leased Premises.  Lessee shall have the
right to designate a representative of Lessee


                                         -26-
<PAGE>

to accompany Lessor and its representatives during the audit; provided, exercise
of such right does not alter the scheduling of the audit.  Audits conducted by
Lessor pursuant to this Article 19 are for Lessor's benefit only.  Lessor shall
not disclose any such audit, or information learned through such audit to any
third party, including any governmental authority, without the prior consent of
Lessee, except for an emergency situation as set forth in Article 13, and except
as otherwise required by law.  Lessor shall, at Lessee's request, disclose all
findings within the scope of such audit to Lessee, and in all cases, shall
provide a copy of such audit to Lessee.  In the event Lessor discovers that
Lessee is not in compliance with applicable laws or other covenants of this
Lease in any material respect, whenever reasonably necessary Lessor may, but
shall have no obligation to, take the least disruptive action necessary to
remedy such noncompliance by Lessee and protect the legitimate interests of
Lessor; provided however, except in emergency situations, Lessor shall afford
Lessee the prior opportunity to take such action within a ten (10) day period
(or shorter if warranted by the circumstances) before instituting any such
action, and Lessor shall only act, if at all, if Lessee fails to take any action
within the prescribed period or fails to diligently continue to implement such
action.  In the event Lessor takes any such remedial action, Lessor shall not be
liable for inconvenience, annoyance, disturbance, loss or interruption of
business, by reason of making such reasonable and good faith determination and
taking such action; provided, however, Lessor shall be liable to Lessee for any
negligence or reckless disregard caused by Lessor, its employees, agents,
consultants, and contractors with respect to any action under this Article 19. 
Lessor agrees in exercising its rights under this Article 19 to act in good
faith to avoid unreasonable interference with Lessee's operations at the TI
Expressway Site.


                                      ARTICLE 20
                                ENTRY/RIGHT OF ACCESS

     Due to the interconnectedness of the infrastructure serving the various
buildings on the TI Expressway Site, Lessor will require and Lessee hereby
agrees to grant to authorized personnel of Lessor (i) access to certain
infrastructure and utilities systems located in those areas of the North
Building indicated as "TI required access" areas on Exhibit A-4 hereto, as and
to the extent reasonably required by Lessor, and (ii) the right to continue to
monitor on Lessor's supervisory control and data acquisition ("SCADA") system,
utilities and process gas and fluid distribution systems located in the Leased
Premises that connect to the site-wide distribution system.

     Lessor and its representatives may, acting in good faith to minimize to the
extent reasonably possible interference with Lessee's operations at the Leased
Premises and upon at least twenty-four (24) hours' prior notice to Lessee
(except in the case of emergency), and subject to any applicable U.S. Government
security requirements, enter the Leased Premises for any of the following
purposes:

     (a)  to make repairs to the Leased Premises required of Lessor under this
Lease;

     (b)  to provide access to the Leased Premises during normal business hours
for authorized third parties, including without limitation, governmental
agencies and, with the consent of Lessee,


                                         -27-
<PAGE>

which shall not be unreasonably withheld or delayed, lenders, brokers,
purchasers, appraisers and, during the last eighteen (18) months of the Lease
Term prospective tenants;

     (c)  to inspect the Leased Premises and determine Lessee's compliance with
this Lease;

     (d)  to audit the compliance by Lessee as permitted in Article 19;

     (e)  to respond to emergency situations;

     (f)  to perform any work, which Lessor elects and is entitled to undertake,
made necessary by reason of any default by Lessee under the terms of this Lease;

     (g)  to carry out any other activity of Lessor permitted under this Lease;
and

     (h)  to perform services for Lessee hereunder.

     Nothing herein shall be construed to impose or imply any duty upon Lessor
to do any such work which, under any provision of this Lease, it is not required
to perform; and the performance thereof by Lessor shall not constitute a waiver
of Lessee's default.  Lessee shall reasonably cooperate with Lessor to ensure
provision of keys, combinations or codes as necessary to ensure adequate and
(where appropriate) immediate access to the Leased Premises as reasonably
required to provide Lessor with the access granted above.  Lessee shall have the
right to designate a representative of Lessee to accompany Lessor and its
representatives when Lessor or its representatives are present on the Leased
Premises.


                                      ARTICLE 21
                              BUILDING SYSTEMS SHUTDOWNS

     Lessee acknowledges that Lessor may, from time to time during emergencies
or for purposes of building maintenance, need to shut down one or more of the
Utility Systems serving the buildings in which the Leased Premises are located.

     Lessee agrees to reasonably cooperate with Lessor to allow Lessor to shut
down building systems for up to five (5) days annually to perform Utilities
Systems maintenance.  Except in the case of an emergency, Lessor shall schedule
such shutdown with at least two (2) months notice to Lessee and prior approval
by Lessee, which approval shall not be unreasonably withheld or delayed.  Lessor
will cooperate with Lessee regarding all shutdowns so as to minimize any
potential disruption to Lessee's operations.

     Lessee acknowledges that  Utilities Systems shutdowns performed in
accordance with this Article 21 will benefit Lessee and Lessee's operations. 
Lessor shall not be liable for inconvenience, annoyance, disturbance, loss or
interruption of business to Lessee.  Lessor shall not be liable for any other
claimed damage to Lessee, by reason of any such Utilities Systems shutdown,
except to the


                                         -28-
<PAGE>

extent due to the gross negligence or willful misconduct of Lessor or its
agents, employees, or contractors, nor shall Lessee be entitled to any abatement
of Rent by reason of any such Utilities Systems shutdown.


                                      ARTICLE 22
                                     HOLDING-OVER

     If Lessee continues to occupy the Leased Premises beyond the Lease Term of
this Lease in the absence of a mutually agreed upon extended term, such
holding-over shall constitute a tenancy at will, except upon hold-over all the
monthly Rent rates shall increase to a sum of 150% of the then current Rent in
effect at the time of expiration of this Lease.


                                      ARTICLE 23
                           SURRENDER OF THE LEASED PREMISES

     Upon surrender of the Leased Premises for any reason, including
termination, abandonment, expiration or breach by Lessor, Lessee, at its expense
(except as otherwise expressly provided herein) shall remove from the Leased
Premises Lessee's Property, except for such Alterations that Lessor has agreed
that may at Lessee's election, be surrendered.  Lessee will use all reasonable
efforts to avoid causing damage to the surrounding structure and to minimize
disruption of Lessor's operations.  Subject to Articles 10 and 11, Lessee, at
its expense, will promptly repair any damage to the Leased Premises caused by
any removal of Lessee's property and Alterations therefrom and restore the
Leased Premises substantially to the same condition as at the commencement of
the Lease (without such equipment as Lessee is removing), reasonable wear and
tear and Alterations that Lessor states in writing may be surrendered at the
termination of the Lease excepted.  Lessor's acceptance of any surrender of the
Leased Premises by Lessee shall not be deemed to constitute a waiver by Lessor
of any default by Lessee.  Any of Lessee's Property not removed after surrender
shall become the property of Lessor.  Upon such surrender, Lessee shall not
allow or cause any environmental, health, or safety permits or authorizations
relating to Lessee's use or occupancy of the Leased Premises to expire,
terminate, or lapse for a period of sixty (60) days after such surrender and
shall, at Lessor's request, execute such documentation as may be necessary or
desirable to transfer any such permits or authorizations to Lessor or Lessor's
designee.

     SECTION 24.01.  LESSEE'S EVENTS OF DEFAULT.

     The following events shall be deemed to be "Events of Default" by Lessee

     (a)  Lessee's failure to timely pay any installment of Rent or to make any
other payment as specified herein within ten (10) days after actual receipt by
Lessee of notice from Lessor of Lessee's failure to pay the past due amounts; or

     (b)  For non-monetary obligations, Lessee's breach of or failure to comply
with any term, provision, representation, warranty, or covenant of this Lease,
and Lessee's failure to cure such breach or noncompliance within thirty (30)
days after actual receipt by Lessee of notice thereof from Lessor or with
Lessor's consent, which shall not be unreasonably withheld, within such longer
time as may reasonably be required to cure the default.

     SECTION 24.02.  EVENTS OF DEFAULT BY LESSOR.

     The following events shall be deemed to be "Events of Default" by Lessor
under this Lease:

     (a)  Lessor's breach of or failure to comply with any term, provision,
representation, warranty or covenant of this Lease, and

          (i)   Lessor's failure to make a payment due from Lessor under this
     Lease or apply appropriate credit to Lessee as specified herein within ten
     (10) days after actual receipt by Lessor of notice from Lessee of Lessor's
     failure to pay the past due amounts or apply the appropriate credit, or

          (ii)  For nonmonetary obligations, Lessor's failure to cure such
     breach or non-compliance within thirty (30) days after actual receipt of
     notice thereof from Lessee or such longer time as may reasonably be
     required to cure the default.

     SECTION 25.01.  LESSOR'S REMEDIES.

     If an Event of Default by Lessee shall have occurred, Lessor shall have the
right, at its election, then or at any time thereafter while such Event of
Default shall continue, to pursue any one or more of the following remedies,
without any notice or demand whatsoever:

     (a)  Terminate this Lease, without any liability whatsoever, in which
event, Lessee shall immediately surrender the Leased Premises to Lessor, and if
Lessee fails to do so, Lessor may, without prejudice to any other remedy which
it may have for possession or arrearages in Rent, enter upon or take possession
of the Leased Premises and expel or remove Lessee and any other person who may
be occupying the Leased Premises or any part thereof without being liable for
prosecution or any claim for damages therefor, and Lessee agrees to pay to
Lessor, on demand, the amount of all loss and damage, including attorneys' fees,
which Lessor may suffer by reason of such termination;

     (b)  Enter upon the Leased Premises without being liable for prosecution or
any claim for damages therefor, correct such default and, upon demand, recover
from Lessee all reasonable amounts expended, as Rent; or otherwise do whatever
Lessee is obligated to do under the terms of this Lease; and Lessee agrees to
reimburse Lessor, on demand, for any expenses, including attorneys' fees, which
Lessor may incur in connection with its attempts to effect compliance with
Lessee's obligations under this Lease, and Lessee further agrees that Lessor
shall not be liable for any damages resulting to Lessee from such action, except
to the extent caused by the gross negligence or willful misconduct of Lessor; or

     (c)  Enter upon and take custodial possession of the Leased Premises, and
use reasonable efforts to re-let the Leased Premises for a use comparable to
that of Lessee for the balance of the then current term without thereby causing
a termination or anticipatory breach of the Lease.

     Pursuit of the foregoing remedies shall not preclude pursuit of any other
remedies herein provided or any other remedies provided by law or equity, nor
shall pursuit herein provided constitute a forfeiture or waiver of any Rent due
to Lessor hereunder or any damages accruing to Lessor by reason of the violation
of any of the terms, provisions or covenants herein contained.  Failure by
Lessor to enforce one or more of the remedies provided herein upon an Event of
Default by Lessee shall not be deemed or construed to constitute a waiver of
such default, or any other violation or breach of any of the terms, provisions
or covenants herein contained.

     SECTION 25.02.  LESSEE'S REMEDIES.

     If an Event of Default by Lessor shall have occurred, Lessee shall have the
right, at its election, then or at any time while such Event of Default shall
continue, to pursue any one or more of the following remedies without any notice
or demand whatsoever:

     (a)  Terminate this Lease, in which event, Lessee shall immediately
surrender the Leased Premises to Lessor, and such date of surrender shall be
treated as if it were the date set forth above for the termination of the then
current term of the Lease; provided, however, Lessee may also assert any claim
Lessee may have against Lessor for amounts due from Lessor to Lessee hereunder
or for any other breach by Lessor hereunder.  Lessor agrees to pay to Lessee, on
demand, the amount of all loss and damage, including attorneys' fees, which
Lessee may suffer by reason of such termination, and provided, however, Lessee
shall at all times be entitled to remove Lessee's property and Alterations
installed and paid for by Lessee from the Leased Premises, or

     (b)  Correct such default and, upon demand, recover from the Lessor, upon
invoice, all amounts reasonably expended; or otherwise do whatever Lessor is
obligated to do under the terms of this Lease; and Lessor agrees to reimburse
Lessee promptly, on demand, for any reasonable expenses, including attorneys'
fees, which Lessee may incur in connection with its attempts to effect
compliance with Lessor's obligations under this Lease, and Lessor further agrees
that Lessee shall not be liable for any damages resulting, to the Lessor from
such action, except to the extent caused by the gross negligence or willful
misconduct of Lessee.


                                         -31-
<PAGE>

     Pursuit of the foregoing remedies shall not preclude pursuit of any other
remedies herein provided or any other remedies provided by law or equity; nor
shall pursuit herein provided constitute a forfeiture or waiver of any amount
due from Lessor to Lessee hereunder or any damages accruing to Lessee by reason
of the violation or otherwise due pursuant to any of the terms, provisions, or
covenants herein contained.  Failure by Lessee to enforce one or more of the
remedies provided herein upon an Event of Default by Lessor shall not be deemed
or construed to constitute a waiver of such default, or any other violation or
breach of any of the terms, provisions or covenants herein contained.

                                  ENFORCEMENT COSTS

     The court costs and attorneys' fees incurred by the party who successfully
prosecutes or defends any legal or equitable proceeding to enforce any right or
obligation hereunder, shall be borne by the other party.  Such costs and fees
shall be due and payable from the date a final, non-appealable judgment is
entered.

     No waiver or failure to object to a breach of any of the provisions of this
Lease, whether express or implied, in any instance, shall be construed to be, or
operate as, a waiver of any prior or succeeding breach of the same or any other
provision of this Lease.

                             TRIQUINT SEMICONDUCTOR, INC.
                                  GUARANTY AGREEMENT

     This is a GUARANTY AGREEMENT, dated as of January 13, 1998 (the
"GUARANTY"), between TriQuint Semiconductor, Inc., a Delaware corporation (the
"GUARANTOR"), and Raytheon TI Systems, Inc., a Delaware corporation (the
"SELLER").

     WHEREAS, pursuant to an Asset Purchase Agreement, dated as of
January 8, 1998 (the "ASSET PURCHASE AGREEMENT"), between the Seller and the
Guarantor, the Guarantor has agreed to purchase certain assets, and assume
certain liabilities of the Seller on the terms and conditions set forth in the
Asset Purchase Agreement;

     WHEREAS, the Guarantor has assigned its rights to purchase such assets, and
assume such liabilities, under the Asset Purchase Agreement to its wholly-owned
subsidiary, TriQuint Semiconductor Texas, Inc., a Delaware corporation (the
"BUYER"); and

     WHEREAS, the Seller has required that the Guarantor, as the holder of all
of the issued and outstanding capital stock of the Buyer, guarantee all
obligations of the Buyer under or in connection with the Asset Purchase
Agreement, in connection with the performance by the Buyer of its obligations
under or in connection with the Asset Purchase Agreement in order to induce the
Seller to consummate the transactions contemplated by the Asset Purchase
Agreement and as consideration for the benefits accruing to the Guarantor as a
result of the transactions contemplated by the Asset Purchase Agreement.

     NOW, THEREFORE, in consideration of the premises contained herein and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

     Section 1.     GUARANTY OF PAYMENT AND PERFORMANCE OF OBLIGATIONS.  The
Guarantor hereby unconditionally guaranties to the Seller the payment and
performance in full of each Obligation (as hereinafter defined), when and as
such Obligation becomes due and payable or is otherwise required to be
performed, including all Obligations which would become due but for the
operation of the automatic stay pursuant to Section 362(a) of the Federal
Bankruptcy Code and the operation of Sections 502(b) and 506(b) of the Federal
Bankruptcy Code.  As used herein, "Obligations" means all indebtedness,
obligations and liabilities of the Buyer to the Seller and its Affiliates,
existing on the date of this Guaranty or arising thereafter, direct or indirect,
absolute or contingent, matured or unmatured, liquidated or unliquidated,
secured or unsecured, arising under or pursuant to the Asset Purchase

<PAGE>

                                         -2-

Agreement, the Intellectual Property Agreement, the Supply Agreement, the Master
Services Agreement, the Sublease Agreements (each as defined in the Asset
Purchase Agreement), the Transition Agreements referred to in the Sublease
Agreements, the Non-Disclosure Agreement or any subcontract or work
authorization agreement entered into pursuant to the Asset Purchase Agreement or
the Master Services Agreement.  The Guarantor agrees that if the Buyer shall
fail to pay or perform any Obligation when and as such Obligation shall be due
and payable or is otherwise required to be performed as set forth in the Asset
Purchase Agreement or the other applicable agreement or instrument, then the
Guarantor will make such payment of such Obligation in funds immediately
available to the Seller or otherwise perform such Obligation if such Obligation
does not entail the payment of money.  This Guaranty is an absolute,
unconditional and continuing guaranty of the full and punctual payment and
performance by the Buyer of the Obligations and not of their collectibility
only, and is in no way conditioned upon any requirement that the Seller first
attempt to collect any of the Obligations from the Buyer or resort to any
security or other means of obtaining payment of the Obligations that the Seller
now has or may acquire after the date hereof, or upon any other contingency
whatsoever.  Payments or performance by the Guarantor hereunder may be required
by the Seller on any number of occasions.

     Section 2.     GUARANTOR'S FURTHER AGREEMENTS TO PAY.  The Guarantor
further agrees, as the principal obligor and not as the guarantor only, to pay
to the Seller forthwith upon demand by the Seller in funds immediately available
to the Seller, all costs and expenses (including court costs and reasonable
legal expenses) incurred or expended by the Seller in connection with collecting
under this Guaranty and the enforcement hereof, together with interest on
amounts recoverable under this Guaranty from the later of (i) the date that such
amounts have become due and payable under the Asset Purchase Agreement or other
applicable agreement or instrument executed pursuant thereto, as finally
determined in accordance with the provisions of the Asset Purchase Agreement or
such other agreement or instrument, and (ii) the date demand for payment
hereunder is made, until payment, at a rate per annum equal to the "prime rate"
as in effect from time to time (determined based on the prime rate published in
the Wall Street Journal under the heading "Money Rates") plus 2%, provided that
the maximum amount of interest that may be charged to or collected from the
Guarantor under this Guaranty shall be absolutely limited to, and shall in no
event exceed, the maximum amount of interest that could lawfully be charged or
collected under applicable law.

     Section 3.     TERMINATION OF GUARANTY.  The obligations of the Guarantor
under this Guaranty shall continue in full force and effect until the
Obligations are finally paid and satisfied in full, provided that this Guaranty
shall continue to be effective or shall be reinstated, as the case may be, if at
any time payment or other satisfaction of any of the Obligations is rescinded or
must otherwise be restored or returned upon the bankruptcy, insolvency, or
reorganization of the Buyer, or otherwise, as though such payment had not been
made or other satisfaction occurred.

<PAGE>

                                         -3-

No invalidity, irregularity or unenforceability by reason of the federal
Bankruptcy Code or any insolvency or other similar law, or any law or order of
any government or agency thereof purporting to reduce, amend or otherwise affect
the Obligations shall impair, affect, or be a defense to or claim against the
obligations of the Guarantor under this Guaranty.

     Section 4.     WAIVERS BY GUARANTOR; SELLER'S FREEDOM TO ACT.  The
Guarantor agrees that the Obligations will be paid and performed strictly in
accordance with their respective terms, regardless of any law, regulation or
order now or hereafter in effect in any jurisdiction affecting any of such terms
or the rights of the Seller with respect thereto. The Guarantor waives
promptness, diligence, presentment, demand, protest, notice of acceptance,
notice of any Obligations incurred and all other notices of any kind, other than
demand for payment hereunder, and all defenses which may be available by virtue
of any valuation, stay, moratorium law or other similar law now or hereafter in
effect, any right to require the marshalling of assets of the Buyer or any other
entity or other Person (as defined in the Asset Purchase Agreement) primarily or
secondarily liable with respect to any of the Obligations, and all suretyship
defenses generally.  Without limiting the generality of the foregoing, the
Guarantor agrees to the provisions of any instrument evidencing, securing or
otherwise executed in connection with any Obligation and agrees that the
obligations of the Guarantor hereunder shall not be released or discharged, in
whole or in part, or otherwise affected by (i) the failure of the Seller to
assert any claim or demand or to enforce any right or remedy against the Buyer
or any other entity or other Person primarily or secondarily liable with respect
to any of the Obligations; (ii) any extensions, compromise, consolidation or
renewals of any Obligation; (iii) any change in the time, place or manner of
payment of any of the Obligations or any rescissions, waivers, compromise,
consolidation, amendments or modifications of any of the terms or provisions of
the Asset Purchase Agreement or any other agreement evidencing, securing or
otherwise executed in connection with any of the Obligations; (iv) the addition,
substitution or release of any entity or other Person primarily or secondarily
liable for any Obligation; (v) the adequacy of any rights which the Seller may
have against any collateral security or other means of obtaining repayment of
any of the Obligations; (vi) the impairment of any collateral securing any of
the Obligations, including without limitation the failure to perfect or preserve
any rights which the Seller might have in such collateral security or the
substitution, exchange, surrender, release, loss or destruction of any such
collateral security; or (vii) any other act or omission which might in any
manner or to any extent vary the risk of the Guarantor or otherwise operate as a
release or discharge of the Guarantor, all of which may be done without notice
to the Guarantor.  To the fullest extent permitted by law, the Guarantor hereby
expressly waives any and all rights or defenses arising by reason of (A) any
"one action" or "anti-deficiency" law which would otherwise prevent the Seller
from bringing any action, including any claim for a deficiency, or exercising
any other right or remedy (including any right of set-off), against the
Guarantor before or after the Seller's commencement or completion of any action,
whether judicially, by exercise of power of sale or

<PAGE>

                                         -4-

otherwise, or (B) any other law which in any other way would otherwise require
any election of remedies by the Seller.

     Section 5.     BUYER'S DEFENSES AVAILABLE TO GUARANTOR.  Notwithstanding
anything to the contrary contained herein, but without in any way affecting the
Guarantor's waiver of suretyship defenses generally pursuant to Section 4, the
Guarantor shall be entitled to rely on any defenses to the payment or
performance of any Obligation that the Buyer is entitled to rely on pursuant to
the Asset Purchase Agreement, other than any defenses that are personal to the
Buyer such as lack of capacity or authority or discharge in bankruptcy.

     Section 6.     UNENFORCEABILITY OF OBLIGATIONS AGAINST THE BUYER.  If for
any reason the Buyer has no legal existence or is under no legal obligation to
discharge any of the Obligations, or if any of the Obligations have become
irrecoverable from the Buyer by reason of the Buyer's insolvency, bankruptcy or
reorganization or by other operation of law or for any other reason, this
Guaranty shall nevertheless be binding on the Guarantor to the same extent as if
the Guarantor at all times had been the principal obligor on all such
Obligations.  In the event that acceleration of the time for payment or
performance of any of the Obligations is stayed upon the insolvency, bankruptcy
or reorganization of the Buyer, or for any other reason, all such amounts
otherwise subject to acceleration under the terms of the Asset Purchase
Agreement or any other agreement evidencing, securing or otherwise executed in
connection with any Obligation shall be immediately due and payable by the
Guarantor.

     Section 7.     SUBROGATION.  Until the final payment and performance in
full of all of the Obligations:  (i) the Guarantor shall not exercise any rights
against the Buyer arising as a result of payment or performance by the Guarantor
hereunder, by way of subrogation, reimbursement, restitution, contribution or
otherwise, and will not prove any claim in competition with the Seller in
respect of any payment hereunder in any bankruptcy, insolvency or reorganization
case or proceedings of any nature; (ii) the Guarantor will not claim any setoff,
recoupment or counterclaim against the Buyer in respect of any liability of the
Guarantor to the Buyer; and (iii) the Guarantor waives any benefit of and any
right to participate in any collateral security which may be held by the Seller.

     Section 8.     FURTHER ASSURANCES.  The Guarantor agrees to do all such
things and execute all such documents as the Seller may consider necessary or
desirable to give full effect to this Guaranty and to perfect and preserve the
rights and powers of the Seller hereunder.  The Guarantor acknowledges and
confirms that the Guarantor itself has established its own adequate means of
obtaining from the Buyer on a continuing basis all information desired by the
Guarantor concerning the financial condition of the Buyer and that the Guarantor
will look to the Buyer and not to the Seller in order for the Guarantor to keep
adequately informed of changes in the financial condition of the Buyer.

Quasi-M/L2800 (9/94)

MASTER LEASE AGREEMENT
(Quasi)

THIS MASTER LEASE AGREEMENT, dated as of 6/27/97 ("Agreement"), between 
General Electric Capital Corporation, with an office at 4 North Park Drive 
Suite 500, Hunt Valley, MD, 21030 (hereinafter called, together with its 
successors and assigns, if any, "Lessor"), and Triquint Semiconductor, Inc., 
a corporation organized and existing under the laws of the State of Delaware 
___ with its mailing address and chief place of business at 2320 NE Brookwood 
Parkway, Hillsboro, OR 97124 (hereinafter called "Lessee").

WITNESSETH:

I. LEASING:

(a) Subject to the terms and conditions set forth below, Lessor agrees to 
lease to Lessee, and Lessee agrees to lease from Lessor, the equipment 
("Equipment") described in Annex A to any schedule hereto ("Schedule"). Terms 
defined in a Schedule and not otherwise defined herein shall have the 
meanings ascribed to them in such Schedule. (b) The obligation of Lessor to 
purchase Equipment from the manufacturer or supplier thereof ("Supplier") and 
to lease the same to Lessee under any Schedule shall be subject to receipt by 
Lessor, prior to the Lease commencement Date (with respect to such 
Equipment), of each of the following documents in form and substance 
satisfactory to Lessor: (i) a Schedule relating to the Equipment then to be 
leased hereunder, (ii) paid in full invoice or other evidence of ownership of 
the Equipment, (iii) evidence of insurance which complies with the 
requirements of Section IX, and (iv) such other documents as Lessor may 
reasonably request. As a further condition to such obligations of Lessor, 
Lessee shall, upon delivery of such Equipment (but not later than the Last 
Delivery Date specified in the applicable Schedule) execute and deliver to 
Lessor a Certificate of Acceptance (in the form of Annex C to the applicable 
Schedule) covering such Equipment. Lessor hereby appoints Lessee its agent 
for inspection and acceptance of the Equipment from the Supplier. Upon 
execution by Lessee of any Certificate of Acceptance, the Equipment described 
thereon shall be deemed to have been delivered to, and irrevocably accepted 
by, Lessee for lease hereunder.

II. TERM, RENT AND PAYMENT:

(a) The rent payable hereunder and Lessee's right to use the Equipment shall 
commence on the date of execution by Lessee of the Certificate of Acceptance 
for such Equipment ("Lease Commencement Date"). The term of this Agreement 
shall be the period specified in the applicable Schedule. If any term is 
extended, the word "term" shall be deemed to refer to all extended terms, and 
all provisions of this Agreement shall apply during any extended terms, 
except as may be otherwise specifically provided in writing. (b) Rent shall 
be paid to Lessor at its address stated above, except as otherwise directed 
by Lessor. Payments of rent shall be in the amount set forth in, and due in 
accordance with the provisions of the applicable Schedule. If one or more 
Advance Rentals are payable, such Advance Rental shall be (i) set forth on 
the applicable Schedule, (ii) due upon acceptance by Lessor of such Schedule, 
and (iii) when received by Lessor, applied to the first rent payment and the 
balance, if any, to the final rental payment(s) under such Schedule. In no 
event shall any Advance Rental or any other rent payments be refunded to 
Lessee. If rent is not paid within ten days of its due 


<PAGE>

date, Lessee agrees to pay a late charge of five cents ($0.05) per dollar on, 
and in addition to, the amount of such rent but not exceeding the lawful 
maximum, if any.

III. TAXES:

Lessee shall have no liability for taxes imposed by the United States of 
America or any State or political subdivision thereof which are on or 
measured by the net income of Lessor. Lessee shall report (to the extent that 
it is legally permissible) and pay promptly all other taxes, fees and 
assessments due, imposed, assessed or levied against any Equipment (or the 
purchase, ownership, delivery, leasing, possession, use or operation 
thereof), this Agreement (or any rentals or receipts hereunder), any 
Schedule, Lessor or Lessee by any foreign, federal, state or local government 
or taxing authority during or related to the term of this Agreement, 
including, without limitation, all license and registration fees, and all 
sales, use, personal property, excise, gross receipts, franchise, stamp or 
other taxes, imports, duties and charges, together with any penalties, fines 
or interest thereon (all hereinafter called "Taxes"). Lessee shall (i) 
reimburse Lessor upon receipt of written request for reimbursement for any 
Taxes charged to or assessed against Lessor accompanied by such information 
as may reasonably enable Lessee to verify the amount of such Taxes, 
(provided, however, that nothing herein shall require Lessor to produce any 
tax bill relating to any personal property other than the Equipment or to any 
leases or other agreement between Lessor and any third party), (ii) on 
request of Lessor, submit to lessor written evidence of Lessee's payment of 
Taxes, (iii) send a copy thereof to Lessor.

IV. REPORTS:

(a) Lessee will notify Lessor in writing, within ten days after Lessee 
receives actual written notice that any tax lien or other lien arising by, 
through or under any party other than Lessor to any equipment, of the full 
particulars thereof and of the location of such equipment on the date of such 
notification. (b) Lessee will within 120 days of the close of each fiscal 
year of Lessee, deliver to Lessor, Lessee's balance sheet and profit and loss 
statement, certified by a recognized firm of certified public accountants.  
Upon request Lessee will deliver to Lessor quarterly, within 90 days of the 
close of each fiscal quarter of Lessee, in reasonable detail, copies of 
Lessee's quarterly financial report certified by an officer of Lessee.  (c) 
Lessee will permit Lessor to inspect any Equipment during normal business 
hours upon at least twenty-four hours prior written notice; provided that 
Lessor shall comply with Lessee's policies and procedures regarding clean 
room safety, confidentiality and shall sign a waiver of liability. (d) Lessee 
will keep the Equipment at the Equipment Location (specified in the 
applicable Schedule) and will promptly notify Lessor of any relocation of 
Equipment. Upon the written request of Lessor, Lessee will notify Lessor 
forthwith in writing of the location of any Equipment as of the date of such 
notification. (e) Lessee will promptly and fully report to lessor in writing 
if any Equipment is lost or damaged (where the estimated repair costs would 
exceed 20% of its then fair market value), or is otherwise involved in an 
accident causing personal injury or property damage. (f) Within 60 days after 
any request by Lessor, Lessee will furnish a certificate of an authorized 
officer of Lessee stating that he has reviewed the activities of Lessee and 
that, to the best of his knowledge, there exists no default (as described in 
Section XI) or event which with notice or lapse of time (or both) would 
become such a default.

V. DELIVERY, USE AND OPERATION:

(a) All Equipment shall be shipped directly from the Supplier to Lessee. (b) 
Lessee agrees that the Equipment will be used by Lessee solely in the conduct 
of its business and in a manner complying 


<PAGE>

with all applicable federal, state, and local laws and regulations. (c) 
LESSEE SHALL NOT ASSIGN, MORTGAGE, SUBLET OR HYPOTHECATE ANY EQUIPMENT, OR 
THE INTEREST OF LESSEE HEREUNDER NOR SHALL LESSEE REMOVE ANY EQUIPMENT FROM 
THE CONTINENTAL UNITED STATES, WITHOUT THE PRIOR WRITTEN CONSENT OF THE 
LESSOR. (d) Lessee will keep the Equipment free and clear of all liens and 
encumbrances other than those which are granted in favor of or result from 
acts of Lessor.

VI. SERVICE:

(a) Lessee will, at its sole expense, maintain each unit of Equipment in good 
operating order, repair, condition and appearance in accordance with 
manufacturer's recommendations, normal wear and tear excepted. Lessee shall, 
if at any time reasonably requested by Lessor, affix in a prominent position 
on each unit of Equipment plates, tags or other identifying labels showing 
ownership thereof by Lessee and Lessor's security interest therein. (b) 
Lessee will not, without the prior consent of Lessor, affix or install any 
accessory, equipment or device on any Equipment if such addition will impair 
the originally intended function or use of such Equipment. All additions, 
repairs, parts, supplies, accessories, equipment, and devices furnished, 
attached or affixed to any Equipment which are not readily removable shall be 
made only in compliance with applicable law, and shall become subject to the 
lien of Lessor. Lessee will not, without the prior written consent of Lessor 
and subject to such conditions as Lessor may impose for its protection, affix 
or install any Equipment to or in any other personal or real property. (c) 
Any alterations or modifications to the Equipment that may, at any time 
during the term of this Agreement, be required to comply with any applicable 
law, rule or regulation shall be made at the expense of Lessee.

VII. STIPULATED LOSS VALUE:

Lessee shall promptly and fully notify Lessor in writing if any unit of 
Equipment shall be or become worn out, lost, stolen, destroyed, irreparably 
damaged in the reasonable determination of Lessee, or permanently rendered 
unfit for use from any cause whatsoever (such occurrences being hereinafter 
called "Casualty Occurrences"). On the rental payment date next succeeding a 
Casualty Occurrence (the "Payment Date"), Lessee shall pay Lessor the sum of 
(x) the Stipulated Loss Value of such unit calculated as of the rental 
payment date next preceding such Casualty Occurrence ("Calculation Date"); 
and (y) all rental and other amounts which are due hereunder as of the 
Payment Date. Upon payment of all sums due hereunder, the term of this lease 
as to such unit shall terminate and (except in the case of the loss, theft or 
complete destruction of such unit) Lessor shall be entitled to recover 
possession of such unit.

VIII. LOSS OR DAMAGE:

Lessee hereby assumes and shall bear the entire risk of any loss, theft, 
damage to, or destruction of, any unit of Equipment from any cause whatsoever 
from the time the Equipment is shipped to Lessee.

IX. INSURANCE:

Lessee agrees, at its own expense, to keep all Equipment insured for such 
amounts and against such hazards as Lessor may reasonably require, including, 
but not limited to, insurance for damage to or loss of such Equipment and 
liability coverage for personal injuries, death or property damage, with 
Lessor named as additional insured and with a loss payable clause in favor of 
Lessor, as its interest may appear, irrespective of any breach of warranty or 
other act or omission of Lessee. The insurance shall provide (i) liability 
coverage in an amount equal to at least ONE MILLION U.S. DOLLARS 


<PAGE>

($1,000,000.00) total liability per occurrence, and (ii) casualty/property 
damage coverage in an amount equal to the higher of the Stipulated Loss value 
or the full replacement cost of the Equipment; or at such other amounts as 
may reasonably be required by Lessor. All such policies shall be with 
companies, and on terms, satisfactory to Lessor. Lessee agrees to deliver to 
Lessor evidence of insurance satisfactory to Lessor. No insurance shall be 
subject to any co-insurance clause. Lessee shall cause all insurers to issue 
checks for payments covering casualty losses to the Equipment payable to the 
order of Lessor only, and no other payee.  If Lessee fails to do so, or if 
notwithstanding Lessee's instructions the insurer issues any check payable 
jointly to Lessee and Lessor, then Lessee shall upon Lessor's request 
promptly endorse any and every such check as directed by Lessor. Lessee and 
Lessor agree that the foregoing provision may be specifically enforced by a 
court of competent jurisdiction. Any reasonable expense of Lessor in 
adjusting or collecting insurance shall be borne by Lessee. Lessee will not 
make adjustments with insurers except (i) with respect to claims for damage 
to any unit of Equipment where the repair costs do not exceed 20% of such 
unit's fair market value, or (ii) with Lessor's written consent. Said 
policies shall provide that the insurance may not be altered or canceled by 
the insurer until after thirty (30) days written notice to Lessor. Except in 
the event of a Casualty Occurrence, Lessor shall, at Lessee's option, apply 
proceeds of insurance, in whole or in part, to (i) repair or replace 
Equipment or any portion thereof, or (ii) satisfy any obligation of Lessee to 
Lessor hereunder.

X. RETURN OF EQUIPMENT:

(a) Upon any expiration or termination of this Agreement or any Schedule, 
Lessee shall promptly, at its own cost and expense: (i) perform any testing 
and repairs required to place the affected units of Equipment in the same 
condition and appearance as when received by Lessee (reasonable wear and tear 
excepted) and in good working order for their originally intended purpose; 
(ii) if deinstallation, disassembly or crating is required, cause such units 
to be deinstalled, disassembled and crated by an authorized manufacturer's 
representative or such other service person as is satisfactory to Lessor, and 
(iii) return such units to a location within the continental United States as 
Lessor shall direct. (b) Until Lessee has fully complied with the 
requirements of Section X(a) above, Lessee's rent payment obligation and all 
other obligations under this Agreement shall continue from month to month 
notwithstanding any expiration or termination of the lease term. Lessor may 
terminate such continued leasehold interest upon ten (10) days notice to 
Lessee.

XI. DEFAULT:

(a) Lessor may in writing declare this Agreement in default if: Lessee 
breaches its obligation to pay rent or any other sum when due and fails to 
cure the breach within ten (10) days; Lessee breaches any of its insurance 
obligations under Section IX; Lessee breaches any of its other obligations to 
Lessor hereunder or under any instrument, document or agreement between 
Lessor and Lessee and fails to cure that breach within thirty (30) days after 
written notice thereof; any representation or warranty made by Lessee in 
connection with this Agreement shall be false or misleading in any material 
respect; Lessee becomes insolvent or ceases to do business as a going 
concern; any Equipment is illegally used; or a petition is filed by or 
against Lessee under any bankruptcy or insolvency laws. Such declaration 
shall apply to all Schedules except as specifically excepted by Lessor. (b) 
After default, at the request of Lessor, Lessee shall comply with the 
provisions of Section X(a). Lessee hereby authorizes Lessor, after a default, 
to enter, with or without legal process, any premises where any Equipment is 
believed to be and take possession thereof so long as Lessor repairs any and 
all damage caused by Lessor to the premises of Lessee in doing so.  Lessee 
shall, without further 


<PAGE>

demand, forthwith pay to Lessor (i) as liquidated damages for loss of a 
bargain and not as a penalty, the Stipulated Loss Value of the Equipment 
(calculated as of the rental next preceding the declaration of default), and 
(ii) all rentals and other sums then due hereunder. Lessor may, but shall not 
be required to, sell Equipment at private or public sale, in bulk or in 
parcels, with or without notice, and without having the Equipment present at 
the place of sale; or Lessor may, but shall not be required to, lease, 
otherwise dispose of or keep idle all or part of the Equipment. With Lessee's 
prior written consent, Lessor may use Lessee's premises for any or all of the 
foregoing at no charge to Lessor. If the Equipment is removed due to Lessee's 
failure to give such consent, such removal will not be raised as a defense to 
a deficiency claim asserted by Lessor. The proceeds of sale, lease or other 
disposition, if any, shall be applied in the following order of priorities: 
(1) to pay all of Lessor's costs, charges and expenses incurred in taking, 
removing, holding, repairing and selling, leasing or otherwise disposing of 
Equipment; then (2) to the extent not previously paid by Lessee, to pay 
Lessor all sums due from Lessee hereunder, then (3) to reimburse to Lessee 
any sums previously paid by Lessee as liquidated damages; and (4) any surplus 
shall be retained by Lessor. Lessee shall pay any deficiency in (1) and (2) 
forthwith. (c) The foregoing remedies are cumulative, and any or all thereof 
may be exercised in lieu of or in addition to each other or any remedies at 
law, in equity, or under statute. The parties agree that a notice of sale or 
other disposition (and the time and place thereof) to which Lessor is 
entitled will be deemed reasonable notice if such notice is received by 
Lessee at least five (5) days prior to any such sale or other disposition. 
The parties further agree that any advertising reasonably calculated to 
notify qualified potential buyers of any such sale or other disposition will 
be deemed reasonable. Lessee shall pay Lessor's actual attorney's fees 
incurred in connection with the enforcement, assertion, defense or 
preservation of Lessor's rights and remedies hereunder, or if prohibited by 
law, such lesser sum as may be permitted. Waiver of any default shall not be 
a waiver of any other subsequent default. (d) Any default under the terms of 
this or any other agreement between Lessor and Lessee may be declared by 
Lessor a default under this and any such other agreement.

XII. ASSIGNMENT:

Lessor may, without the consent of Lessee, assign this Agreement or any 
Schedule. Lessee agrees that if Lessee receives written notice of an 
assignment from Lessor, Lessee will pay all rent and other amounts payable 
under any assigned Equipment Schedule to such assignee or as instructed by 
Lessor. Lessee further agrees to confirm in writing receipt of a notice of 
assignment as may be reasonable request by assignee. Lessee hereby waives and 
agrees not to assert against any such assignee any defense, set-off, 
recoupment claim or counterclaim which Lessee has or may at any time have 
against Lessor for any reason whatsoever.

XIII. NET LEASE; NO SET-OFF, ETC:

This Agreement is a net lease. Lessee's obligation to pay rent and other 
amounts due hereunder shall be absolute and unconditional. Lessee shall not 
be entitled to any abatement or reductions of, or set-offs against, said rent 
or other amounts, including, without limitation, those arising or allegedly 
arising out of claims (present or future, alleged or actual, and including 
claims arising out of strict tort or negligence of Lessor) of Lessee against 
Lessor under this Agreement or otherwise. Nor shall this Agreement terminate 
or the obligations of Lessee be affected by reason of any defect in or damage 
to, or loss of possession, use or destruction of, any Equipment from 
whatsoever cause.  It is the intention of the parties that rents and other 
amounts due hereunder shall continue to be payable in 


<PAGE>

all events in the manner and at the times set forth herein unless the 
obligation to do so shall have been terminated pursuant to the express terms 
hereof.

XIV. INDEMNIFICATION:

(a) Lessee hereby agrees to indemnify, save and keep harmless Lessor, its 
agents, employees, successors and assigns from and against any and all 
losses, damages, penalties, injuries, claims, actions and suits, including 
legal expenses, of whatsoever kind and nature, in contract or tort, whether 
caused by the active or passive negligence of Lessor or otherwise, and 
including, but not limited to, Lessor's strict liability in tort, arising out 
of (i) the selection, manufacture, purchase, acceptance or rejection of 
Equipment, the ownership of Equipment during the term of this Agreement, and 
the delivery, lease, possession, maintenance, uses, condition, return or 
operation of Equipment (including, without limitation, latent and other 
defects, whether or not discoverable by Lessor or Lessee and any claim for 
patent, trademark or copyright infringement or environmental damage) or (ii) 
the condition of Equipment sold or disposed of after use by Lessee, any 
sublessee or employees of Lessee. Lessee shall, upon request, defend any 
actions based on, or arising out of, any of the foregoing. Notwithstanding 
the foregoing, Lessee shall not be obligated to indemnify, defend, save and 
keep harmless Lessor, its agents, employees, successors and assigns from and 
against any and all losses, damages, penalties, injuries, claims, actions or 
suits arising out of or resulting from the gross negligence or willful 
misconduct of Lessor, its agents, employee, successors and assigns. (b) All 
of Lessor's rights, privileges and indemnities contained in this Section XIV 
shall survive the expiration or other termination of this Agreement and the 
rights, privileges and indemnities contained herein are expressly made for 
the benefit of, and shall be enforceable by Lessor, its successors and 
assigns.

XV. DISCLAIMER:

LESSEE ACKNOWLEDGES THAT IT HAS SELECTED THE EQUIPMENT WITHOUT ANY ASSISTANCE 
FROM LESSOR, ITS AGENTS OR EMPLOYEES. LESSOR DOES NOT MAKE, HAS NOT MADE, NOR 
SHALL BE DEEMED TO MAKE OR HAVE MADE, ANY WARRANTY OR REPRESENTATION, EITHER 
EXPRESS OR IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE EQUIPMENT LEASED 
HEREUNDER OR ANY COMPONENT THEREOF, INCLUDING, WITHOUT LIMITATION, ANY 
WARRANTY AS TO DESIGN, COMPLIANCE WITH SPECIFICATIONS, QUALITY OF MATERIALS 
OR WORKMANSHIP, MERCHANTABILITY, FITNESS FOR ANY PURPOSE, USE OR OPERATION, 
SAFETY, PATENT, TRADEMARK OR COPYRIGHT INFRINGEMENT, OR TITLE. All such 
risks, as between Lessor and Lessee, are to be borne by Lessee. Without 
limiting the foregoing, Lessor shall have no responsibility or liability to 
Lessee or any other person with respect to any of the following, regardless 
of any negligence of Lessor (i) any liability, loss or damage caused or 
alleged to be caused directly or indirectly by any Equipment, any inadequacy 
thereof, any deficiency or defect (latent or otherwise) therein, or any other 
circumstance in connection therewith; (ii) the use, operation or performance 
of any Equipment or any risks relating thereto; (iii) any interruption of 
service, loss of business or anticipated profits or consequential damages; or 
(iv) the delivery, operation, servicing, maintenance, repair, improvement or 
replacement of any Equipment. If, and so long as, no default exists under 
this Lease, Lessee shall be, and hereby is, authorized during the term of 
this Lease to assert and enforce, at Lessee's sole cost and expense, from 
time to time, in the name of and for the account of Lessor and/or Lessee, as 
their interests may appear, whatever claims and rights Lessor may have 
against any Supplier of the Equipment.


<PAGE>

XVI. REPRESENTATIONS AND WARRANTIES OF LESSEE:

Lessee hereby represents and warrants to Lessor that on the date hereof and 
on the date of execution of each Schedule: (a) Lessee has adequate power and 
capacity to enter into, and perform under, this Agreement and all related 
documents (together, the "Documents") and is duly qualified to do business 
wherever necessary to carry on its present business and operations, including 
the jurisdiction(s) where the Equipment is or is to be located. (b) The 
Documents have been duly authorized, executed and delivered by Lessee and 
constitute valid, legal and binding agreements, enforceable in accordance 
with their terms, except to the extent that the enforcement of remedies 
therein provided may be limited under applicable bankruptcy and insolvency 
laws. (c) No approval, consent or withholding of objections is required from 
any governmental authority or instrumentality with respect to the entry into 
or performance by Lessee of the Documents except such as have already be 
obtained. (d) The entry into and performance by Lessee of the Documents will 
not: (i) violate any judgment, order, law or regulation applicable to Lessee 
or any provision of Lessee's Certificate of Incorporation or By-Laws; or (ii) 
result in any breach of, constitute a default under or result in the creation 
of any lien, charge, security interest or other encumbrance upon any 
Equipment pursuant to any indenture, mortgage, deed of trust, bank loan or 
credit agreement or other instrument (other than this Agreement) to which 
Lessee is a party. (e) There are no suits or proceedings pending or 
threatened in court or before any commission, board or other administrative 
agency against or affecting Lessee, which will have a material adverse effect 
on the ability of Lessee to fulfil its obligations under this Agreement other 
than those disclosed in the Lessee's first fiscal quarter, March 29, 1997, 
form 10-Q. (f) The Equipment accepted under any Certificate of Acceptance is 
and will remain tangible personal property. (g) Each Balance Sheet and 
Statement of Income delivered to Lessor has been prepared in accordance with 
generally accepted accounting principles, and since the date of the most 
recent such Balance Sheet and Statement of Income, there has been no material 
adverse change. (h) Lessee is and will be at all times validly existing and 
in good standing under the laws of the State of its incorporation (specified 
in the first sentence of this Agreement). (i) The Equipment will at all times 
be used for commercial or business purposes.

XVII. OWNERSHIP FOR TAX PURPOSES, GRANT OF SECURITY INTEREST; USURY SAVINGS:

(a) For income tax purposes, the parties hereto agree that it is their mutual 
intention that Lessee shall be considered the owner of the Equipment. 
Accordingly, Lessor agrees (i) to treat Lessee as the owner of the Equipment 
on its federal income tax return, (ii) not to take actions or positions 
inconsistent with such treatment on or with respect to its federal income tax 
return, and (iii) not to claim any tax benefits available to an owner of the 
Equipment on or with respect to its federal income tax return. The foregoing 
undertakings by Lessor shall not be violated by Lessor's taking a tax 
position inconsistent with the forgoing sentence to the extent such a 
position is required by law or is taken through inadvertence so long as such 
inadvertent tax position is reversed by Lessor promptly upon its delivery. 
Lessor shall in no event be liable to Lessee if Lessee fails to secure any of 
the tax benefits available to the owner of the Equipment. (b) Lessee hereby 
grants to Lessor a first security interest in the Equipment, together with 
all additions, attachments, accessions, accessories and accessions thereto 
whether or not furnished by the Supplier of the Equipment and any and all 
substitutions, replacements or exchanges therefor, and any and all insurance 
and/or other proceeds of any of the forgoing in and against which a security 
interest is granted hereunder. Notwithstanding anything to the contrary 
contained elsewhere in this Agreement, to the extent that Lessor asserts a 
purchase money security interest in any items of Equipment ("PMSI 
Equipment"):  (i) the PMSI 


<PAGE>

Equipment shall secure only those sums which have been advanced by Lessor for 
the purchase of the PMSI Equipment, or the acquisition of rights therein, or 
the use thereof (the "PMSI Indebtedness"), and (ii) no other Equipment shall 
secure the PMSI Indebtedness. (c) It is the intention of the parties hereto 
to comply with any applicable usury laws to the extent that any Schedule is 
determined to be subject to such laws; accordingly, it is agreed that, 
notwithstanding any provision to the contrary in any Schedule or the Lease, 
in no event shall any Schedule require the payment or permit the collection 
of interest in excess of the maximum amount permitted by applicable law. If 
any such excess interest is contracted for, charged or received under any 
Schedule or the Lease, or in the event that all of the principal balance 
shall be prepaid, so that under any of such circumstances the amount of 
interest contracted for, charged or received under any Schedule or the Lease 
shall exceed the maximum amount of interest permitted by applicable law, then 
in such event (a) the provisions of this paragraph shall govern and control, 
(b) neither Lessee nor any other person or entity now or hereafter liable for 
the payment hereof shall be obligated to pay the amount of such interest to 
the extent that it is in excess of the maximum amount of interest permitted 
by applicable law, (c) any such excess which may have been collected shall be 
either applied as a credit against the then unpaid principal balance or 
refunded to Lessee, at the option of the Lessor, and (d) the effective rate 
of interest shall be automatically reduced to the maximum lawful contract 
rate allowed under applicable law as now or hereafter construed by the courts 
having jurisdiction thereof. It is further agreed that without limitation of 
the foregoing, all calculations of the rate of interest contracted for, 
charged or received under any Schedule or the Lease which are made for the 
purpose of determining whether such rate exceeds the maximum lawful contract 
rate, shall be made, to the extent permitted by applicable law, by 
amortizing, prorating, allocating and spreading in equal parts during the 
period of the full stated term of the indebtedness evidenced hereby, all 
interest at any time contracted for, charged or received from Lessee or 
otherwise by Lessor in connection with such indebtedness; provided, however, 
that if any applicable state law is amended or the law of the United States 
of America preempts any applicable state law, so that it becomes lawful for 
Lessor to receive a greater interest per annum rate than is presently 
allowed, the Lessee agrees that, on the effective date of such amendment or 
preemption, as the case may be, the lawful maximum hereunder shall be 
increased to the maximum interest per annum rate allowed by the amended 
stated law or the law of the United States of America.

XVIII. EARLY TERMINATION:

(a) On or after the First Termination Date (specified in the applicable 
Schedule), Lessee may, so long as no default exists hereunder, terminate this 
Agreement as to all (but not less than all) of the Equipment on such Schedule 
as of a Rent Payment Date ("Termination Date") upon at least 60 days prior 
written notice to Lessor. (b) Lessee shall, and Lessor may, solicit cash bids 
for the Equipment on an AS IS, WHERE IS BASIS without recourse to or warranty 
from Lessor, express or implied ("AS IS BASIS"). Prior to the Termination 
Date, Lessee shall (i) certify to Lessor any bids received by Lessee and (ii) 
pay to Lessor (A) the Termination Value (calculated as of the rental due on 
the Termination Date) for the Equipment, and (B) all rent and other sums due 
and unpaid as of the Termination Date. (c) Provided that all amounts due 
hereunder have been paid on the Termination Date, Lessor shall (i) sell the 
Equipment on an AS IS BASIS for cash to the highest bidder and (ii) refund 
the proceeds of such sale (net of any related expenses) to Lessee up to the 
amount of the Termination Value. If such sale is not consummated, no 
termination shall occur and Lessor shall refund the Termination Value (less 
any expenses incurred by Lessor) to Lessee. (d) Notwithstanding the 
foregoing, Lessor may elect by written notice, at any time prior to the 
Termination Date, not to 


<PAGE>

sell the Equipment. In that event, on the Termination Date Lessee shall (i) 
return the Equipment (in accordance with Section X) and (ii) pay to Lessor 
all amounts required under Section XVIII(b) less the amount of the highest 
bid certified by Lessee to Lessor.

XIX. EARLY PURCHASE OPTION:

(a) Provided that the Lease has not been earlier terminated and provided 
further than Lessee is not in default under the Lease or any other agreement 
between Lessor and Lessee. Lessee may, UPON AT LEAST 30 DAYS BUT NO MORE THAN 
270 DAYS PRIOR WRITTEN NOTICE TO LESSOR OF LESSEE'S IRREVOCABLE ELECTION TO 
EXERCISE SUCH OPTION, purchase all (but not less than all) of the Equipment 
listed and described in this schedule on any Rent Payment Date following the 
First Termination Date as set forth in this Schedule, and prior to the date 
which is the scheduled expiration of this Lease, (the "Early Purchase Date") 
for a price equal to (i) the Termination Value (calculated as of the Early 
Purchase Date) for the Equipment, and (ii) all rent and other sums due and 
unpaid as of the Purchase Date (the "Early Option Price"), plus all 
applicable sales taxes on an AS IS BASIS. (The purchase option granted by 
this subsection shall be referred to herein as the "Early Purchase Option"). 
(b) If Lessee exercises its Early Purchase Option with respect to the 
Equipment leased hereunder, then on the Early Purchase Date, Lessee shall pay 
to Lessor any rent and other sums due and unpaid on the Early Purchase Date 
and Lessee shall pay the Early Option Price, plus all applicable sales taxes, 
to Lessor in cash.

XX. PURCHASE OPTION:

(a) So long as no default exists hereunder and the lease has not been earlier 
terminated, Lessee may at lease expiration purchase all (but not less than 
all) of the Equipment in any Schedule on an AS IS, WHERE IS BASIS for cash 
equal to the amount indicated in such Schedule (the "Option Payment"). The 
Option Payment shall be due and payable in immediately available funds on the 
Expiration Date. (b) Lessee shall be deemed to have waived this option unless 
it provides Lessor with written notice of its irrevocable election to 
exercise the same not less than 90 days prior to the Expiration Date.

XXI. MISCELLANEOUS:

(a) LESSEE HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY 
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR 
INDIRECTLY, THIS LEASE, ANY OF THE RELATED DOCUMENTS, ANY DEALINGS BETWEEN 
LESSEE AND LESSOR RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY 
RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED 
BETWEEN LESSEE AND LESSOR. The scope of this waiver is intended to be all 
encompassing of any and all disputes that may be filed in any court 
(including, without limitation, contract claims, tort claims, breach of duty 
claims, and all other common law and statutory claims). THIS WAIVER IS 
IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, 
AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, 
SUPPLEMENTS OR MODIFICATIONS TO THIS LEASE, ANY RELATED DOCUMENTS, OR TO ANY 
OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED 
TRANSACTION. In the event of litigation, this lease may be filed as a written 
consent to a trial by the court. (b) Unless and until Lessee exercises its 
rights under Section XIX above, nothing herein contained shall give or convey 
to lessee any right, title or interest in and to any Equipment except as a 
lessee. Any cancellation or termination by Lessor, pursuant to the provision 
of this Agreement, any Schedule, 


<PAGE>

supplement or amendment hereto, or the lease of any Equipment hereunder, 
shall not release Lessee from any then outstanding obligations to Lessor 
hereunder. All Equipment shall at all times remain personal property of 
Lessor regardless of the degree of its annexation to any real property and 
shall not by reason of any installation in, or affixation to, real or 
personal property become a part thereof. (c) Time is of the essence of this 
Agreement. Lessor's failure at any time to require strict performance by 
Lessee of any of the provisions hereof shall not waive or diminish Lessor's 
right thereafter to demand strict compliance therewith. Lessee agrees, upon 
Lessor's request, to execute any instrument necessary or expedient for 
filing, recording or perfecting the interest of Lessor. All notices required 
to be given hereunder shall be deemed adequately given if sent by registered 
or certified mail to the addressee at its address stated herein, or at such 
other place as such addressee may have designated in writing. This Agreement 
and any Schedule and Annexes thereto constitute the entire agreement of the 
parties with respect to the subject matter hereof. NO VARIATION OR 
MODIFICATION OF THIS AGREEMENT OR ANY WAIVER OF ANY OF ITS PROVISIONS OR 
CONDITIONS, SHALL BE VALID UNLESS IN WRITING AND SIGNED BY AN AUTHORIZED 
REPRESENTATIVE OF THE PARTIES HERETO.

- ----------------------------------------------------
                                            initials

(d) In case of a failure of Lessee to comply with any provision of this 
Agreement, Lessor shall have the right, but shall not be obligated to, effect 
such compliance, in whole or in part; and all moneys spent and expenses and 
obligations incurred or assumed by Lessor in effecting such compliance shall 
constitute additional rent due to Lessor within twenty days after the date 
Lessor sends notice to Lessee requesting payment. Lessor's effecting such 
compliance shall not be a waiver of Lessee's default. (e) Any rent or other 
amount not paid to Lessor when due hereunder shall bear interest, both before 
and after any judgment or termination hereof, at the lesser of the interest 
rate computed on a per annum basis at the Prime Rate (as published by the 
Wall Street Journal) plus 3 percent, but such interest rate shall be no less 
than 11 percent, or the maximum rate allowed by law. Any provisions in this 
Agreement and any Schedule which are in conflict with any statute, law or 
applicable rule shall be deemed omitted, modified or altered to conform 
thereto.

IN WITNESS WHEREOF, Lessee and Lessor have caused this Agreement to be 
executed by their duly authorized representatives as of the date first above 
written.

MASTER LEASE AGREEMENT
DATED __________, 1997 (the "Lease")
BY AND BETWEEN
Triquint Semiconductor, Inc. ("Lessee")
AND
GENERAL ELECTRIC CAPITAL CORPORATION ("Lessor")
DATED __________, 1997

WHEREAS, Lessor and Lessee desire to amend certain provisions of the Lease as 
hereinafter provided;

NOW THEREFORE, for good and valuable consideration, receipt and sufficiency 
of which are hereby acknowledged, Lessor and Lessee hereby agree to amend the 
Lease by adding the following language:

Section XI of the Lease is amended in the following manner:

(e)  Any other bonds, debentures, notes, leases or other indebtedness for 
money borrowed (hereinafter collectively called "Obligations") of the Lessee 
or of any of the Lessee's subsidiaries shall become immediately due and 
payable in advance of its scheduled maturity following a default or the 
Lessee or any of the Lessee's subsidiaries defaults in the repayment of any 
such Obligations at the maturity thereof (after giving effect to any 
applicable grace period therefor) or any guarantee of or indemnity in respect 
of any Obligations of others given by the Lessee or any of the Lessee's 
subsidiaries shall not be honored when due and called upon (after giving 
effect to any applicable grace period therefor) or any guarantee of or 
indemnity in respect of any Obligations of others given by the Lessee or any 
of the Lessee's subsidiaries shall not be honored when due and called upon 
(after giving effect to any applicable grace period therefor); Lessee hereby 
agrees to notify the Lessor immediately upon receipt of any declared default 
by any obligee.  Failure to do so shall constitute an immediate material 
default under this Lease.

This Amendment shall be deemed to have been entered into contemporaneously 
with and integrated into the terms and conditions of this Lease.

Except as set out herein, the terms and conditions of the Lease shall remain 
in full force and effect as entered into by the parties on or prior to the 
date hereof.

of December __, 1997, between GENERAL ELECTRIC CAPITAL CORPORATION 
(hereinafter called, together with its successors and assigns, if any 
"Lessor"), and TRIQUINT SEMICONDUCTOR, INC. (hereinafter called "Lessee").  
Capitalized terms used by not defined herein shall have the meanings ascribed

<PAGE>

    (B) at the expiration of the Third Renewal Term Lessee fails to exercise 
    its purchase option, then the following terms shall apply:

              (1)  Definitions of Certain Terms.  For purposes of this 
    Section XX:

                   (A)  "EQUIPMENT" means all and not less than all of the 
              items of Equipment described on the Schedule;

<PAGE>

                   (B)  "ESTIMATED RESIDUAL VALUE" means the relevant 
              percentage, as set out in Exhibit 1 to this Schedule, of 
              Lessor's Cost of the Equipment as set out on the Schedule;

                   (C)  "REALIZED VALUE" means the net proceeds realized by 
              Lessor from sale of the Equipment after deduction of (x) 
              expenses of such sale, if any, and (y) all sums due and owing 
              under the Lease as of Schedule Expiration that remain unpaid as 
              of the Date of the sale;

                   (D)  "SCHEDULE EXPIRATION" means the last day of the Basic 
              Term or one of the Renewal Terms of the Lease, as appropriate, 
              as to the Equipment.

              (2)  DETERMINATION OF REALIZED VALUE.  The Realized Value for 
    each item of Equipment on the Schedule shall be determined as follows:

        Lessee and Lessor shall arrange for the sale of such Equipment on an 
    as is basis, provided that Lessee may not bid, directly or indirectly.  
    Each item of Equipment shall be sold by Lessor to the highest bidder.  
    The Realized Value shall be determined based on the cash proceeds 
    received by Lessor from such sale, as provided in Section XX(e)(1)(C), 
    above.  If any item of Equipment is not sold within 30 days after the 
    applicable Term Expiration, then Lessee and Lessor agree, in view of the 
    uncertainties of market conditions and the parties' inability to predict 
    what the actual sale price of such item would be, that the Realized Value 
    of such item shall be deemed to equal zero, for purposes of computing 
    Lessee's liability as provided in paragraph (3) immediately below. Upon 
    the sale of the item at any time after the expiration of such 30 day 
    period, Lessor will apply the Realized Value (i) to refund to Lessee, 
    without interest any amount which Lessee may have previously paid to 
    Lessor with respect to such item under paragraph (3) and (ii) to pay to 
    Lessee the amount by which the Realized Value exceeds the Estimated 
    Residual Value.

              (3)  LESSEE LIABILITY.  If the Realized Value of the Equipment 
    is less than the Estimated Residual Value thereof, Lessor shall notify 
    Lessee of such fact in writing and Lessee shall, within 10 days after 
    receipt of such notice, pay to Lessor, as an adjustment to the rental 
    payable under the Lease, an amount equal to the difference between the 
    Realized Value and the Estimated Residual Value; provided, however, 
    Lessee's liability under this paragraph shall be limited to the 
    applicable Lessee's Maximum Liability as set forth in Exhibit 1.

              (4)  LESSOR LIABILITY.  If the Realized 

<PAGE>

    Value of the Equipment exceeds the Estimated Residual Value thereof, and 
    provided that Lessee is not then in default under the Lease, Lessor shall 
    pay to Lessee, as an adjustment to the rent payable under the Lease, an 
    amount equal to 100% of such excess, but only to the extent Lessor 
    actually receives the Realized Value in available funds.

    Solely with respect to Series "G" Equipment Schedules Lessee agrees 
to the following:

    Notwithstanding anything in the Lease Agreement to the contrary, which 
ever end of lease option the Lessee chooses for the first Series "G" 
equipment Schedules Lessee shall be deemed to have elected to exercise the 
same option for all other Series "G" Equipment Schedules.

Except as expressly, modified hereby, all terms and provisions of the 
Agreement shall remain in full force and effect.  This Schedule is not 
binding or effective with respect to the Agreement or Equipment until 
executed on behalf of Lessor and Lessee by authorized representatives of 
Lessor and Lessee, respectively.

    IN WITNESS WHEREOF, Lessee and Lessor have caused this Schedule to be 
executed by their duly authorized representatives as of the date first above 
written.

    Renewal Term Rent, and on the same day of each of the next 11 months

    liable for all obligations thereunder, including, without limitation, the 
    obligation to continue paying rent.

         (d)  At the end of the Third Renewal Term, upon written notice 
    delivered to Lessor at least 180 days but not more than 270 days prior to 
    the Third Renewal Term expiration date, and so long as no default has 
    occurred and is continuing hereunder and this Agreement has not been 
    earlier terminated, Lessee shall have the option to purchase, for a cash 
    price equal to the applicable Estimated Residual Value (as defined below 
    and as set forth in Exhibit 1 to this Schedule) plus applicable taxes,

    If Lessee elects to purchase the Equipment, then on the Third Renewal 
    Term expiration date, Lessee shall pay to Lessor the purchase price (plus 
    applicable taxes) and all other sums due and unpaid on such date 
    (including but not limited to the last scheduled payment of Third Renewal 
    Term Rent).  If Lessee fails to timely exercise such purchase option 
    Lessee shall, subject to the terms and conditions set out in paragraph 
    (e) of this Section XX, return the Equipment to Lessor.

         (e)  If (A) at the expiration of the Basic Term, or the First 
    Renewal Term, or the Second Renewal Term, as the case may be, Lessee 
    elects to return the Equipment to Lessor, or (B) at the expiration of the

    Section XX:

                   (A) "EQUIPMENT" means all and not less than all of the 
              items of Equipment described on the Schedule;

<PAGE>

                   (B) "ESTIMATED RESIDUAL VALUE" means the relevant 
              percentage, as set out in Exhibit 1 to this Schedule, of 
              Lessor's Cost of the Equipment as set out on the Schedule;

                   (C)  "REALIZED VALUE" means the net proceeds realized by 
              Lessor from sale of the Equipment after deduction of (x) 
              expenses of such sale, if any, and (y) all sums due and owing 
              under the Lease as of Schedule Expiration that remain unpaid as 
              of the Date of the sale;

                   (D)  "SCHEDULE EXPIRATION" means the last day of the Basic 
              Term or one of the Renewal Terms of the Lease, as appropriate, 
              as to the Equipment.

              (2)  DETERMINATION OF REALIZED VALUE.  The Realized Value for 
    each item of Equipment on the Schedule shall be determined as follows:

              Lessee and Lessor shall arrange for the sale of such Equipment 
    on an AS IS BASIS, provided that Lessee may not bid, directly or 
    indirectly.  Each item of Equipment shall be sold by Lessor to the 
    highest bidder.  The Realized Value shall be determined based on the cash 
    proceeds received by Lessor from such sale, as provided in Section 
    XX(e)(1)(C), above.  If any item of Equipment is not sold within 30 days 
    after the applicable Term Expiration, then Lessee and Lessor agree, in 
    view of the uncertainties of market conditions and the parties' inability 
    to predict what the actual sale price of such item would be, that the 
    Realized Value of such item shall be deemed to equal zero, for purposes 
    of computing Lessee's liability as provided in paragraph (3) immediately 
    below. Upon the sale of the item at any time after the expiration of such 
    30 day period, Lessor will apply the Realized Value (i) to refund to 
    Lessee, without interest, any amount which Lessee may have previously 
    paid to Lessor with respect to such item under paragraph (3) and (ii) to 
    pay to Lessee the amount by which the Realized Value exceeds the 
    Estimated Residual Value.

              (3)  Lessee Liability.  If the Realized Value of the Equipment 
    is less than the Estimated Residual Value thereof, Lessor shall notify 
    Lessee of such fact in writing and Lessee shall, within 10 days after 
    receipt of such notice, pay to Lessor, as an adjustment to the rental 
    payable under the Lease, an amount equal to the difference between the 
    Realized Value and the Estimated Residual Value; provided, however, 
    Lessee's liability under this paragraph shall be limited to the 
    applicable Lessee's Maximum Liability as set forth in Exhibit 1.

              (4)  Lessor Liability.  If the Realized Value of the Equipment 
    exceeds the Estimated Residual Value thereof, and provided that Lessee is 
    not then in default under the Lease, Lessor shall pay to Lessee, as an 
    adjustment to the rent payable under the Lease, an amount equal to 100% 
    of such excess, but only to the extent Lessor actually receives the 
    Realized Value in available funds.

    Solely with respect to Series "G" Equipment Schedules Lessee agrees to 
the following:

    Notwithstanding anything in the Lease Agreement to the contrary, which 
ever end of lease option the Lessee chooses for the first Series "G" 
Equipment Schedules Lessee shall be deemed to have elected to exercise the 
same option for all other Series "G" Equipment Schedules.

Except as expressly modified hereby, all terms and provisions of the 
Agreement shall remain in full force and effect.  This Schedule is not 
binding or effective with respect to the Agreement or Equipment until 
executed on behalf of Lessor and Lessee by authorized representatives of 
Lessor and Lessee, respectively.

    IN WITNESS WHEREOF, Lessee and Lessor have caused this Schedule to be 
executed by their duly authorized representatives as of the date first above 
written.

        (d)  At the end of the Third Renewal Term, upon written notice 
    delivered to Lessor at least 180 days but not more than 270 days prior to

    Lessee shall, subject to the terms and conditions set out in paragraph 
    (e) of this Section XX, return the Equipment to Lessor.

        (e) If (A) at the expiration of the Basic Term, or the First Renewal 
    Term, or the Second Renewal 

<PAGE>

    Term, as the case may be, Lessee elects to return the Equipment to 
    Lessor, or (B) at the expiration of the Third Renewal Term Lessee fails 
    to exercise its purchase option, then the following terms shall apply:

             (1)  Definitions of Certain Terms.  For purposes of this 
    Section XX:

                  (A)  "EQUIPMENT" means all and not less than all of the 
    items of Equipment described on the Schedule;

<PAGE>

                  (B)  "ESTIMATED RESIDUAL VALUE" means the relevant 
    percentage, as set out in Exhibit 1 to this Schedule, of Lessor's Cost 
    of the Equipment as set out on the Schedule;

                  (C)  "REALIZED VALUE" means the net proceeds realized by 
    Lessor from sale of the Equipment after deduction of (x) expenses of such 
    sale, if any, and (y) all sums due and owing under the Lease as of 
    Schedule Expiration that remain unpaid as of the Date of the sale;

                  (D)   "SCHEDULE EXPIRATION" means the last day of the Basic 
    Term or one of the Renewal Terms of the Lease, as appropriate, as to the 
    Equipment.

             (2)  Determination of Realized Value.  The Realized Value for 
    each item of Equipment on the Schedule shall be determined as follows:

        Lessee and Lessor shall arrange for the sale of such Equipment on an 
    as is basis, provided that Lessee may not bid, directly or indirectly.  
    Each item of Equipment shall be sold by Lessor to the highest bidder.  
    The Realized Value shall be determined based on the cash proceeds 
    received by Lessor from such sale, as provided in Section XX(e)(1)(C), 
    above.  If any item of Equipment is not sold within 30 days after the 
    applicable Term Expiration, then Lessee and Lessor agree, in view of the 
    uncertainties of market conditions and the parties' inability to predict 
    what the actual sale price of such item would be, that the Realized Value 
    of such item shall be deemed to equal zero, for purposes of computing 
    Lessee's liability as provided in paragraph (3) immediately below. Upon 
    the sale of the item at any time after the expiration of such 30 day 
    period, Lessor will apply the Realized Value (i) to refund to Lessee, 
    without interest, any amount which Lessee may have previously paid to 
    Lessor with respect to such item under paragraph (3) and (ii) to pay to 
    Lessee the amount by which the Realized Value exceeds the Estimated 
    Residual Value.

             (3)  Lessee Liability.  If the Realized Value of the Equipment 
    is less than the Estimated Residual Value thereof, Lessor shall notify 
    Lessee of such fact in writing and Lessee shall, within 10 days after 
    receipt of such notice, pay to Lessor, as an adjustment to the rental 
    payable under the Lease, an amount equal to the difference between the 
    Realized Value and the Estimated Residual Value; provided, however, 
    Lessee's liability under this paragraph shall be limited to the 
    applicable Lessee's Maximum Liability as set forth in Exhibit 1.

             (4)  Lessor Liability.  If the Realized 

<PAGE>

    Value of the Equipment exceeds the Estimated Residual Value thereof, and 
    provided that Lessee is not then in default under the Lease, Lessor shall 
    pay to Lessee, as an adjustment to the rent payable under the Lease, an 
    amount equal to 100% of such excess, but only to the extent Lessor 
    actually receives the Realized Value in available funds.

    Solely with respect to Series "G" Equipment Schedules Lessee agrees to 
    the following:

    Notwithstanding anything in the Lease Agreement to the contrary, which 
ever end of lease option the Lessee chooses for the first Series "G" 
Equipment Schedules Lessee shall be deemed to have elected to exercise the 
same option for ALL other Series "G" Equipment Schedules.

Except as expressly modified hereby, all terms and provisions of the 
Agreement shall remain in full force and effect.  This Schedule is not 
binding or effective with respect to the Agreement or Equipment until 
executed on behalf of Lessor and Lessee by authorized representatives of 
Lessor and Lessee, respectively.

    IN WITNESS WHEREOF, Lessee and Lessor have caused this Schedule to be 
executed by their duly authorized representatives as of the date first above 
written.
