ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS
 
    On December 31, 1997, Fairchild Semiconductor Corporation (the "Company") 
completed the acquisition from Raytheon Company of all of the outstanding 
common stock of Raytheon Semiconductor, Inc. ("Raytheon") for $120 million in 
cash. Raytheon designs, manufactures and markets high-performance analog and 
mixed signal integrated circuits for the personal computer, communications, 
broadcast video and industrial markets. For its fiscal year ended December 
31, 1996, Raytheon reported net sales of $68.4 million, operating profit of 
$8.1 million and total assets of $62.8 million. Immediately prior to closing 
of the transaction, Raytheon was renamed Fairchild Semiconductor Corporation 
of California (the "Subsidiary"), and upon closing, became a wholly-owned 
subsidiary of the Company. The Subsidiary will be operated as the Analog and 
Mixed Signal Products Group. The transaction will be accounted for as a 
purchase.
 
    The purchase price was financed through a combination of borrowings under 
a new $90 million Tranche C term loan within the Company's Senior Term 
Facility, of which approximately $45 million was used to finance the 
acquisition, and existing cash. No borrowings under the Company's Revolving 
Credit Facility were required to finance the acquisition. In conjunction with 
the acquisition, the Company also refinanced its Tranche B term loan with the 
remaining proceeds from the new Tranche C term loan. The new Tranche C term 
loan matures on March 11, 2003, and bears interest based on either the bank's 
base rate or the Eurodollar rate at the option of the Company.

                               Sale of Shares: Closing
                                           
     Section 2.1. Purchase and Sale. On the basis of the representations,
warranties, covenants and agreements and subject to the satisfaction or waiver
of the conditions set forth herein, at the Closing, Buyer will purchase from
Seller and Seller will sell and deliver to Buyer 2,500 Shares owned by Seller
which constitute, and will constitute as of the Closing, one hundred percent
(100%) of the issued and outstanding Shares.

     Section 2.2. Closing Documents. At the Closing: 

     (a)  Seller will deliver certificates for the Shares, with appropriate
stock powers attached, properly signed, and shall execute and deliver to Buyer
such instruments of transfer, duly prepared and executed in accordance with
relevant law, as may be necessary to effect the transfer of the Shares to Buyer
or such Person as Buyer may designate to hold such Shares;

     (b)  Buyer shall pay by wire transfer the Purchase Price in immediately
available funds to the account specified by Seller; and

     (c)  Seller and Buyer shall deliver the certificates and other documents
required to be delivered under Articles IX and X hereof (together, with the
other documents specified in Sections 2.2(a) and 2.2(b) hereof, the "Closing
Documents").

     Section 2.3. Time and Place of Closing. The Closing shall take place on the
Closing Date at 10:00 A.M., Boston time, at the offices of Sullivan & Worcester
LLP, One Post Office Square, Boston, Massachusetts 02109, or such other place or
time as the parties may agree.

     Section 2.4. Purchase Price Adjustment. (a) Included as Schedule 2.4(i)
hereto under the heading "Target" is an unaudited balance sheet of the
Semiconductor Division Business at August 31, 1997 (the "Target Balance Sheet"),
together with a statement of the accounting policies and methodologies on the
basis of which the Target Balance Sheet was prepared (the "Accounting
Policies").  The Target Balance Sheet is a balance sheet prepared by Raytheon on
a basis consistent with the principles used to prepare the Balance Sheet, except
as the Accounting Policies otherwise disclose.  

     (b)  Within 60 days following the Closing, Raytheon shall prepare a 
balance sheet of the Company as of the Closing Date (including the notes 
thereto, the "Closing Balance Sheet"). The Closing Balance Sheet shall fairly 
present the financial position of the Company and shall be prepared using the 
same accounting methods, policies, practices and procedures with consistent 
classifications, judgments, and valuation and estimation methodologies as 
used in the calculation of such items on the Target Balance Sheet except that 
reserves shall not be reduced for reasons other than in respect of cash 
payments since the date of the Target Balance Sheet provided, however, that 
as the result of the Company's disposal of approximately $2,000,000 gross 
book value of obsolete inventory between September 1, 1997 and the date 
hereof, the Company shall 

                                        9
<PAGE>

be permitted to reduce reserves specifically identified to such obsolete 
inventory by an amount not to exceed $2,000,000, but such reduction shall not 
be permitted unless the inventory reserves remaining on the Closing Balance 
Sheet shall include any additional reserves required because of additions to 
inventory subsequent to August 31, 1997.  During the preparation of the 
Closing Balance Sheet and the period of any dispute within the contemplation 
of this Section 2.4, Buyer shall (i) provide Raytheon and Raytheon's 
authorized representatives with access as reasonably necessary to the books, 
records, facilities and employees of the Company, (ii) provide Raytheon 
within ten (10) business days after the Closing Date with normal month-end 
closing financial information for the period ending on the Closing Date and 
(iii) cooperate fully with Raytheon and Raytheon's authorized 
representatives, including the provision on a timely basis of all information 
necessary or useful in preparing the Closing Balance Sheet.  The Target 
Balance Sheet does not, and the Closing Balance Sheet will not, include any 
accrual for liabilities under any "stay on" plans.

     (c) Raytheon shall deliver a copy of the Closing Balance Sheet to Buyer 
promptly after it has been prepared. After receipt of the Closing Balance 
Sheet, Buyer shall have forty (40) days to review the Closing Balance Sheet, 
together with the work papers used in the preparation thereof. Buyer and its 
authorized representatives shall have full access to all relevant books and 
records and employees of Raytheon to the extent required to complete their 
review of the Closing Balance Sheet. Buyer may dispute only those items 
reflected on the Closing Balance Sheet which relate to Net Worth and only on 
the basis that such amounts were not arrived at in accordance with the 
application of the Accounting Policies or financial reporting consistent with 
those applied to the Target Balance Sheet, and using substantially the same 
accounting methods, policies, practices and procedures with consistent 
classifications, judgments, and valuation and estimation methodologies as 
used in the calculation of such items on the Target Balance Sheet. Unless 
Buyer delivers written notice to Raytheon on or prior to the 40th day after 
Buyer's receipt of the Closing Balance Sheet specifying in reasonable detail 
all disputed items and the basis therefor, Buyer shall be deemed to have 
accepted and agreed to the Closing Balance Sheet. If Buyer so notifies 
Raytheon of its objection to the Closing Balance Sheet, Buyer and Raytheon 
shall, within forty-five (45) days following such notice (the "Resolution 
Period"), attempt to resolve their differences and any resolution by them as 
to any disputed amounts shall be final, binding and conclusive.

     (d)  All amounts remaining in dispute shall be submitted to a firm of 
nationally recognized independent public accountants (the "Neutral Auditor") 
selected by Raytheon and Buyer within ten (10) days after the expiration of 
the Resolution Period. If Raytheon and Buyer are unable to agree on the 
Neutral Auditor, then Buyer and Raytheon shall each have the right to request 
the American Arbitration Association to appoint the Neutral Auditor, which 
shall not have had a material relationship with Raytheon or Buyer within the 
past two years. Each party agrees to execute, if requested by the Neutral 
Auditor, a reasonable engagement letter. All fees and expenses relating to 
the work, if any, to be performed by the Neutral Auditor shall be borne 
equally by Raytheon and Buyer.  Using the Accounting Policies, the Neutral 
Auditor shall act as an arbitrator to determine, based solely on 
presentations by Raytheon and Buyer, and not by independent review, only 
those issues still in dispute.  In no event may the Neutral Auditor 

                                       10
<PAGE>


consider any issues, amounts or matters not disputed within the forty-five-day
period provided in Section 2.4(c) hereof.  The Neutral Auditor's determination
shall be made within thirty (30) days of their selection, shall be set forth in
a written statement delivered to Raytheon and Buyer and shall be final, binding
and conclusive. The term "Adjusted Closing Balance Sheet", as hereinafter used,
shall mean the definitive Closing Balance Sheet agreed to by Buyer and Raytheon
in accordance with Section 2.4(c) or the definitive Closing Balance Sheet
resulting from the determinations made by the Neutral Auditor in accordance with
this Section 2.4(d) (in addition to those items theretofore agreed to by
Raytheon and Buyer).

     (e)  The Purchase Price shall be (a) increased dollar for dollar to the 
extent Net Worth reflected in the Adjusted Closing Balance Sheet exceeds, or 
(b) decreased dollar for dollar to the extent Net Worth reflected in the 
Adjusted Closing Balance Sheet is less than the Net Worth of the Company 
reflected in the Target Balance Sheet. Any adjustments to the Purchase Price 
made pursuant to this Section 2.4(e) shall be paid by wire transfer in 
immediately available funds to the account specified by the party to whom 
such payment is owed within five business days after the Adjusted Closing 
Balance Sheet is agreed to by Buyer and Raytheon or any remaining disputed 
items are ultimately determined by the Neutral Auditor.

     Section 2.5.  Intercompany Account; Distributions.  Immediately prior to 
the Closing, Seller will cause the Company to close out the intercompany 
loans account and distribute to Seller all Cash. 

     Section 2.6. Nonassignable Contracts.  Anything in this Agreement to the 
contrary notwithstanding, this Agreement shall not constitute an agreement to 
assign any claim, contractual obligation, Governmental Authorization, lease, 
commitment, sales, service or purchase order, or any claim, right or benefit 
arising thereunder or resulting therefrom, if the Stock Purchase or the 
transfer of the Assets to the Company would be deemed an attempted assignment 
thereof without the required consent of a third party thereto and would 
constitute a breach thereof or in any way affect the rights of Raytheon, 
Seller, Buyer or the Company thereunder.  If such consent is not obtained, or 
if the transfer of the Assets to the Company or consummation of the Stock 
Purchase would affect the rights of the Company thereunder so that Buyer 
would not in fact receive the benefit of all such rights, Raytheon shall 
cooperate with Buyer in any arrangement designed to provide for the benefits 
thereof to the Company, including subcontracting, sublicensing or subleasing 
to the Company or enforcement for the benefit of Buyer of any and all rights 
of the Company against a third party thereto arising out of the breach or 
cancellation by such third party or otherwise; and any assumption by Buyer or 
the Company of obligations thereunder whether by operation of Law in 
connection with the Stock Purchase or in connection with the transfer of the 
Assets to the Company which shall require the consent or approval of any 
third party shall be made subject to such consent or approval being obtained.

                Representations and Warranties of Raytheon and Seller
                                           
     Raytheon and Seller hereby jointly and severally represent and warrant to
Buyer as follows:

and the Company is duly organized and validly existing in the jurisdiction of 
its organization or incorporation and is in good standing and qualified (with 
all requisite power and authority) to transact business in each jurisdiction 
in which the nature of property owned or leased by it in the conduct of the 
Semiconductor Division Business requires it to be so qualified, except where 
the failure to be in good standing or to be duly qualified to transact 
business, would not, individually or in the aggregate, reasonably be expected 
to have an Adverse Effect on the Company.

     (b)  Seller has all requisite power and authority to own the Shares, to 
execute and deliver this Agreement and to consummate the transactions 
contemplated hereby. Raytheon has all requisite corporate authority to 
execute and deliver this Agreement and to consummate the transactions 
contemplated hereby.  The Company has and, prior to the formation of the 
Company, Raytheon had all requisite power and authority to own the Assets and 
to carry on the Semiconductor Division Business as it is now being conducted. 
 The execution and delivery of this Agreement and the consummation of the 
transactions contemplated hereby have been duly and validly authorized by all 
necessary corporate proceedings on the part of Raytheon and Seller. The 
execution, delivery and performance of this Agreement and the consummation of 
the transactions contemplated hereby will not (i) violate any provision of 
Raytheon's, Seller's or the Company's certificate of incorporation, 
declaration of trust or bylaws, as the case may be, (ii) except as disclosed 
in Schedule 3.1(b) hereto, violate or conflict with any provision of, or be 
an event that is (or with the passage of time will result in) a violation of 
or conflict with, or result in the acceleration of or entitle any Person to 
accelerate or cancel (whether after the giving of notice or lapse of time or 
both) any obligation under, or result in the imposition of any Lien upon any 
of the Shares or any of the Assets, pursuant to any Contract or Order to 
which Raytheon, Seller or the Company is a party or by which any of them is 
bound or (iii) except as listed on Schedule 3.1(b), violate or conflict with 
any other material restriction of any kind or character to which Raytheon, 
Seller or the Company is subject, that, in the case of clauses (ii) or (iii), 
would, individually or in the aggregate, reasonably be expected to Adversely 
Affect the Company.  This Agreement has been duly executed and delivered by 
Raytheon and Seller and, assuming the due execution hereof by Buyer, this 
Agreement constitutes the legal, valid and binding obligation of Raytheon and 
Seller, enforceable against each in accordance with its terms.
                                           
     (c)  At the Closing, Seller will deliver to Buyer good title to the 
Shares free and clear of all Liens, including preemptive rights.

Shares, all of which are validly issued, outstanding, fully paid and 
nonassessable and owned by Seller.  There are no outstanding options, 
warrants or other rights of any kind relating to the sale, issuance or voting 
of any shares of capital stock of any class of, or other equity interests in, 
the Company which have been issued, granted, or entered into by Seller.

are in compliance in all material respects with the applicable provisions of 
ERISA and those provisions of the Code applicable to the Benefit Plans and 
each of the Benefit Plans, has been administered at all times, and in all 
material aspects, in accordance with its terms except that in any case in 
which any Benefit Plan is currently required to comply with a provision of 
ERISA or of the Code, but is not yet required to be amended to reflect such 
provision, it has been administered in accordance with such provision.

     (c)  With respect to any Benefit Plan, there has been no (nor will there 
be any as a result of the transactions contemplated by this Agreement) event

open, by consent or otherwise, a group health plan within the meaning of 
section 4980B(g)(2) of the Code.

     (e)  All of the Benefit Plans which are pension benefit plans have 
received determination letters from the Internal Revenue Service ("IRS") to 
the effect that such plans are qualified and exempt from federal income taxes 
under sections 401(a) and 501(a), respectively, of the Code, as amended 
through December 31, 1994; and no determination letter with respect to any 
Benefit Plan has been revoked nor has the Company or any Benefits Party 
received notice of threatened revocation, nor has any Benefit Plan been 
amended since the date of its most recent determination letter in any respect 
that would adversely affect its qualification or materially increase its cost 
nor has any Benefit Plan been amended in a manner that would require security 
to be provided in accordance with section 401(a)(29) of the Code.

     (f)  Neither the Company nor any Benefits Party has incurred any 
material liability to the Pension Benefit Guaranty Corporation ("PBGC") with

by section 412 of the Code.

     (g)  At no time since December 31 1989, have the Company or any Benefits 
Party, been required to contribute to, or incurred any withdrawal liability, 
within the meaning of Section 4201 of ERISA to any multiemployer pension 
plan, within the meaning of Section 3(37) of ERISA, nor does the Company or 
any Benefits Party have any potential withdrawal liability arising from a 
transaction described in Section 4204 of ERISA.

     (h)  Neither the Company nor any Benefits Party has incurred or is 
reasonably likely to incur any material liability with respect to any plan or 
arrangement that would be included within the definition of "Benefit Plan" 
hereunder but for the fact that such plan or arrangement was terminated 
before the date of this Agreement.

     (i)  Except as listed on Schedule 3.11(i) hereto, no payment which is or 
may be made by, from or with respect to any Benefit Plan, to any employee, 
former employee, director or agent of the Company or any Benefits Party, 
either alone or in conjunction with any other payment, will be characterized 
as an excess parachute payment under section 280G of the Code.

     (j)  There are no material pension, welfare, bonus, stock purchase, 
stock ownership, stock option, deferred compensation, incentive, severance, 
termination or other compensation plans or arrangements, or other material 
employee fringe benefit plans presently maintained by, or contributed to by 
the Company, or by any Benefits Party for the benefit of any employee of the 
Company, maintained outside the jurisdiction of the United States.

predictions contained or referred to in the offering materials that have been

warranties of Raytheon or Seller.
      
     Section 3.15.  Environmental Matters.  Except as set forth on Schedule 3.15
hereto:

     (a) (i) Raytheon or the Company has or has applied for all Licenses 
required under Environmental Laws for the operation of the Company's business 
as presently conducted (the "Environmental Permits") and there are no 
violations, and no pending, or, to the knowledge of the director of corporate 
services of Raytheon, threatened, investigations or proceedings with respect 
to such Environmental Permits.

     (ii) The Semiconductor Division is, and as of the Closing the Company

reasonably be expected to have an Adverse Effect on the Semiconductor 
Division or the Company.

    (iii) No written notice, notification, demand, request for information, 
citation, summons, complaint or Order has been received by, is pending, or, 
to the knowledge of the Company, threatened by any Person against, the 
Company in connection with the Semiconductor Division Business nor has any

Division for any alleged violation of any Environmental Law or liability 
thereunder, other than where such notice, notification, demand, request for 
information, citation, summons, complaint or Order has been fully resolved, 
or where the failure to achieve such resolution would not, individually or in 
the aggregate, reasonably be expected to have an Adverse Effect on the 
Company.

presently operated facilities other than the Mountain View Facility:  

     (i)  neither the Company nor the Semiconductor Division uses, possesses,

<PAGE>

Environmental Law, individually or in the aggregate, except for such 
Remediation which would not reasonably be expected to have an Adverse Effect 
on the Company.

     Section 3.16.  Tax Matters.

     (a)  The Company has (i) timely filed all Tax Returns required to be 
filed by it, (ii) paid all Taxes shown to have become due pursuant to such 
Tax Returns and (iii) paid all other Taxes for which a notice of assessment 
or demand for payment has been received.  All Tax Returns are true, correct 
and complete; have been prepared in accordance with all applicable laws and 
requirements; and accurately reflect the taxable income (or other measure of 
tax) of the Company. The accruals for Taxes, other than Income Taxes, 
contained in the Target Balance Sheet are, and in the case of the Closing 
Balance Sheet will be, adequate, to cover all liabilities for Taxes, other 
than Income Taxes, of the Company for all periods ending on or before August 
31, 1997 and the Closing Date, respectively, and include (or will include in 
the case of the Closing Balance Sheet) adequate provision for all deferred 
Taxes, other than Income Taxes, in accordance with generally accepted 
accounting principles, and nothing has occurred subsequent to such dates to 
make any of such accruals inadequate.  All Taxes, other than Income Taxes, of 
the Company for periods after August 31, 1997 through the Closing Date have 
been paid or are adequately reserved against on the books of the Company.  
The Company has timely filed all information returns or reports, including 
forms 1099, that are required to be filed and has accurately reported all 
information required to be included on such returns or reports.  True copies 
of state income tax returns of the Company, and pro forma copies of the 
consolidated federal income tax return that reflects the operations of the 
Company, for each of the fiscal years ended December 31, 1992 through 
December 31, 1996 have been delivered to Buyer.

     (b)  Except as disclosed on Schedule 3.16 hereto, there are no proposed 
assessments of Taxes against the Company, no proposed adjustments to any Tax 
Return pending against the Company and no proposed adjustments to the manner 
in which any Tax of the Company is determined.  Except as disclosed on 
Schedule 3.16 hereto, each Tax Return of the Company has been audited by the 
relevant authorities (and all deficiencies or proposed deficiencies resulting 
from such audits have been paid or are adequately provided for in the 
financial Statements), or the statute of limitations with respect to each Tax 
Return has expired, and no Tax Return is under examination by any taxing 
authority.  No claim has been made by a taxing authority in a jurisdiction 
where the Company does not file Tax Returns that the Company is or may be 
subject to taxation by that jurisdiction.

     (c)  Except as disclosed on Schedule 3.16 hereto, the Company has never 
(i) executed a waiver or consent extending any statute of limitation for any 
Tax liability that remains outstanding, (ii) joined in or been required to 
join in filing a consolidated or combined federal, state or local income Tax 
Return except the consolidated group of which Raytheon is the parent, (iii) 
been the subject of a Tax ruling that will have continuing effect following 
the Closing, (iv) been the subject of a closing agreement with any taxing 
authority that will have continuing effect following the Closing, or (v) 
granted a power of attorney with respect to any Tax matter that has 
continuing effect.

     (d)  The Company does not own any interest in any entity characterized 
as a partnership for federal income tax purposes.

     Section 3.17. Schedules. (a) Any matter described in any Schedule hereto 
shall be deemed to be referred to on all other Schedules hereto to which such 
matter logically relates if such relationship can reasonably be inferred from 
the description of the matter provided in the first such Schedule.

     (b)  The inclusion of any item on any Schedule to this Agreement shall 
not be construed as an indication that such item is material in any respect.

     (c)  Seller shall not be obligated to revise or update any Schedule 
attached hereto.
                                       
                                  Article IV.
                    Representations and Warranties of Buyer
                                       
     Buyer hereby represents and warrants to Seller as follows:

     Section 4.1. Incorporation; Authorization; Etc. Buyer is a corporation 
duly incorporated, validly existing and in good standing under the laws of 
the State of Delaware. Buyer has full corporate power to execute and deliver 
this Agreement, to perform its obligations hereunder and to consummate the 
transactions contemplated hereby. The execution and delivery of this 
Agreement, the performance of Buyer's obligations hereunder and the 
consummation of the transactions contemplated hereby have been duly and 
validly authorized by the Board of Directors of Buyer and no other corporate 
proceedings or actions on the part of Buyer, its Board of Directors or 
stockholders are necessary therefor. The execution, delivery and performance 
of this Agreement will not (i) violate any provision of the charter or bylaws 
or similar organizational instrument of Buyer or any of its Affiliates, (ii) 
violate any provision of, or be an event that is (or with the passage of time 
will result in) a violation of, or result in the acceleration of or entitle 
any party to accelerate (whether after the giving of notice or lapse of time 
or both) any obligation under, or result in the imposition of any lien upon 
or the creation of a security interest in any of Buyer's or any of its 
Affiliates' assets or properties pursuant to, any Contract or Order to which 
Buyer or any of its Affiliates is a party or by which Buyer or any of its 
Affiliates is bound, or (iii) violate or conflict with any other material 
restriction of any kind or character to which Buyer or any of its Affiliates 
is subject, that, in the case of clauses (ii) and (iii), would, individually 
or in the aggregate, reasonably be expected to have an Adverse Effect on 
Buyer or Buyer and its subsidiaries, taken as a whole. This Agreement has 
been duly executed and delivered by Buyer, and, assuming the due execution 
hereof by Seller, this Agreement constitutes the legal, valid and binding 
obligation of Buyer, enforceable against Buyer in accordance with its terms.

     Section 4.2. Brokers, Finders, Etc. Except for the services of CS First 
Boston (which shall be paid for by Buyer), Buyer has not employed, and is not 
subject to the valid claim of, any broker, finder, consultant or other 
intermediary in connection with the transactions contemplated 

                                      22
<PAGE>

by this Agreement who might be entitled to a fee or commission from Seller in 
connection therewith.

     Section 4.3. Licenses, Approvals, Other Authorizations, Consents, 
Reports, Etc. Other than the HSR Act, no filing with, notice to or 
authorization, consent or approval of, any Governmental Authority is required 
to be made, filed, given or obtained by Buyer or any of its Affiliates, in 
connection with the consummation of the Stock Purchase except for (i) those 
that become applicable solely as a result of the specific regulatory status 
of Seller, or (ii) the failure to make, file, give or obtain which would not, 
individually or in the aggregate, reasonably be expected to have an Adverse 
Effect on Buyer or Buyer and its subsidiaries, taken as a whole.

     Section 4.4. Acquisition of the Shares and Operation of Company Business 
for Investment. Buyer has such knowledge and experience in financial and 
business matters that it is capable of evaluating the merits and risks of its 
purchase of the Shares and operation of the Company's business. Buyer 
confirms that Seller has made available to Buyer the opportunity to ask 
questions of the officers of the Company and to acquire additional 
information about the business and financial condition of the Company. 
                                       
                                   Article V.
                    Covenants of Raytheon, Seller and Buyer
                                       
     Section 5.1. Investigation of Business; Access to Properties, Records 
and Employees. (a) Raytheon and Seller shall afford to representatives of 
Buyer reasonable access to the offices, plants, properties, personnel, books 
and records of the Company during normal business hours, in order that Buyer 
may have full opportunity to make such investigations (including, without 
limitation, environmental assessments or studies) as it desires of the 
affairs of the Company; provided, however, that such investigation shall not 
unreasonably disrupt the personnel and operations of Raytheon or the Company. 
If, in the course of any investigation pursuant to this Section 5.1 between 
the execution of this Agreement and the Closing Date, Buyer discovers any 
breach of any representation or warranty contained in this Agreement that 
would constitute grounds upon which Buyer could refuse to close the 
transactions contemplated hereby or any circumstance or condition that, to 
the knowledge of the chief financial officer or general counsel of Buyer, 
would upon Closing constitute such a breach, Buyer covenants that it will 
promptly so inform Raytheon and may not rely on any such breach not disclosed 
as grounds for refusing to close the transactions contemplated hereby, 
provided that no failure by Buyer to disclose any such breach to Raytheon 
shall be used by Raytheon as a defense to Raytheon's duty to indemnify for 
any such breach under Section 11.2 hereof.  Raytheon and Seller acknowledge 
that their representations and warranties in this Agreement shall not 
otherwise be affected or mitigated by any investigation conducted by Buyer or 
its representatives prior to Closing, or by any knowledge of Buyer. 

     (b)  Any information provided to Buyer or its representatives pursuant 
to this Agreement shall be held by Buyer and its representatives in 
accordance with, and shall be subject 

                                       23
<PAGE>

to the terms of, the Confidentiality Agreement dated September 24, 1997 by 
and between Raytheon and Buyer, which is hereby incorporated in this 
Agreement as though fully set forth herein.

     (c)  Buyer agrees to (i) hold all of the books and records of the 
Company existing on the Closing Date and not to destroy or dispose of any 
thereof for a period of five (5) years from the Closing Date or such longer 
time as may be required by law, and thereafter, if it desires to destroy or 
dispose of such books and records, to offer first in writing at least sixty 
(60) days prior to such destruction or disposition to surrender them to 
Raytheon and (ii) following the Closing Date to afford Raytheon, its 
accountants and counsel, during normal business hours, upon reasonable 
request, reasonable access to such books, records and other data and to the 
employees of the Company to the extent that such access may be requested for 
any legitimate purpose, including without limitation responding to 
Governmental Authorities, defending or prosecuting litigation, preparing 
Income Tax Returns and other tax filings and carrying out Raytheon's and 
Seller's responsibilities with respect to Mountain View Environmental 
Liabilities, at no cost to Raytheon or Seller (other than for reasonable 
out-of-pocket expenses); provided, however, that nothing herein shall limit 
any of Raytheon's and Seller's rights of discovery. Buyer shall have the same 
rights, and Raytheon and Seller the same obligations, as are set forth above 
in this Section 5.1(c), with respect to any books and records of Raytheon or 
Seller pertaining to the Semiconductor Division or the Company that are 
retained by Raytheon or Seller, with the exception of Returns relating to 
Taxes that are not the responsibility of Buyer.

     Section 5.2. Best Efforts; Obtaining Consents. (a) Subject to the terms 
and conditions herein provided, each of Raytheon, Seller and Buyer agrees to 
use its best efforts to take, or cause to be taken, all actions and to do, or 
cause to be done, all things necessary, proper or advisable to consummate and 
make effective as promptly as practicable, the transactions contemplated by 
this Agreement and to cooperate with each of the others in connection with 
the foregoing, including using its best efforts (i) to obtain all necessary 
waivers, consents and approvals from other parties to material Contracts, 
(ii) subject to subsection (b) below, to obtain all consents, approvals and 
authorizations that are required to be obtained under any Law, (iii) subject 
to subsection (b) below, to lift or rescind any Order adversely affecting the 
ability of the parties hereto to consummate the Stock Purchase, (iv) to 
effect all necessary registrations and filings including filings under the 
HSR Act and submissions of information requested by Governmental Authorities, 
and (v) to fulfill all conditions to this Agreement (it being understood that 
such efforts shall not include any requirement of Buyer, Raytheon or Seller 
to expend material sums of money or grant any material financial or other 
accommodation). Raytheon, Seller and Buyer further covenant and agree, with 
respect to a threatened or pending Order or Law that would adversely affect 
the ability of the parties hereto to consummate the Stock Purchase, to use 
their respective best efforts to prevent the entry, enactment or promulgation 
thereof, as the case may be (it being understood that such efforts shall not 
include any requirement of Buyer, Raytheon or Seller to expend material sums 
of money or grant any material financial or other accommodation).

     (b) (i)   Each of Raytheon and Seller (together, a "party" for the 
purposes of this Section 5.2(b)) and Buyer shall (A) make or cause to be made 
the filings required of such party or any of 

                                       24
<PAGE>

its subsidiaries or Affiliates under the HSR Act with respect to the 
transactions contemplated hereby as promptly as practicable and in any event 
within two (2) days after the date of this Agreement, (B) comply at the 
earliest practicable date with any request under the HSR Act for additional 
information, documents, or other materials received by such party or any of 
its subsidiaries from the Federal Trade Commission or the Department of 
Justice (either, an "HSR Authority") or any other Governmental Authority in 
respect of such filings or such transactions, and (c) cooperate with the 
other party in connection with any such filing (including, with respect to 
the party making a filing, providing copies of all such documents to the 
nonfiling party and its advisors prior to filing and, if requested, to accept 
all reasonable changes suggested in connection therewith) and in connection 
with resolving any investigation or other inquiry of any such agency or other 
Governmental Authority under any Antitrust Laws (as defined in Section 
5.2(b)(ii) hereof  with respect to any such filing or any such transaction.  
Each party shall use its best efforts to furnish to each other all 
information required for any application or other filing to be made pursuant 
to any applicable Law in connection with the Stock Purchase and the other 
transactions contemplated by this Agreement.  Each party shall promptly 
inform the other party of any communication with, and any proposed 
understanding, undertaking, or agreement with, any Governmental Authority 
regarding any such filings or any such transaction.  Neither party shall 
independently participate in any formal meeting with any Governmental 
Authority in respect of any such filings, investigation or other inquiry 
without giving the other party prior notice of the meeting and, to the extent 
permitted by such Governmental Authority, the opportunity to attend and/or 
participate. The parties hereto will consult and cooperate with one another 
in connection with any analyses, appearances, presentations, memoranda, 
briefs, arguments, opinions and proposals made or submitted by or on behalf 
of any party hereto in connection with proceedings under or relating to the 
HSR Act or other Antitrust Laws.

     (ii) Each of Raytheon, Seller and Buyer shall use its best efforts to 
resolve such objections, if any, as may be asserted by any Governmental 
Authority with respect to the transactions contemplated by this Agreement 
under the HSR Act, the Sherman Act, as amended, the Clayton Act, as amended, 
the Federal Trade Commission Act, as amended, and any other federal, state or 
foreign statutes, rules, regulations, orders, decrees, administrative or 
judicial doctrines or other laws that are designed to prohibit, restrict or 
regulate actions having the purpose or effect of monopolization or restraint 
of trade (collectively, "Antitrust Laws").  In connection therewith, if any 
administrative or judicial action or proceeding is instituted (or threatened 
to be instituted) challenging any transaction contemplated by this Agreement 
as violative of any Antitrust Law, each of Raytheon, Seller and Buyer shall 
cooperate and use its best efforts vigorously to contest and resist any such 
action or proceeding, including any legislative, administrative or judicial 
action, and to have vacated, lifted, reversed or overturned any decree, 
judgment, injunction or other order, whether temporary, preliminary or 
permanent, that is in effect and that prohibits, prevents, or restricts 
consummation of the Stock Purchase or any other transactions contemplated by 
this Agreement, and vigorously to pursue all available avenues of 
administrative and judicial appeal and all available legislative action, 
unless by mutual agreement Raytheon, Seller and Buyer decide that litigation 
is not in their respective best interest.  Each of Raytheon, Seller and Buyer 
shall use its best efforts to take such action as may be required to cause 
the expiration of the notice period under the HSR Act or other Antitrust 

                                       25
<PAGE>

Laws with respect to such transactions as promptly as possible after the 
execution of this Agreement.

     (c)  Raytheon shall use its best efforts to obtain the transfer to the 
Company of the resale rights of the products of New Japan Radio Co. Ltd. 
("NJRC") and any other transferable benefits flowing from the existing 
relationship between Raytheon and NJRC. For the six months after Closing, 
Raytheon agrees to assist Buyer as Raytheon deems practicable if Buyer 
attempts to obtain a seat on the board of directors of NJRC.  Raytheon shall 
also cooperate with Buyer in any effort to enforce and implement the terms of 
any agreement or licensing arrangement relating to the Semiconductor Division 
Business involving Raytheon, the Company or NJRC. Effective on the Closing 
Date, Raytheon will grant Buyer a six month option to purchase the shares of 
NJRC now owned by Raytheon at market price. 

     (d)  In case at any time after the Closing any further action is 
necessary or desirable to carry out the purposes of this Section 5.2, the 
proper officers and/or directors of Raytheon, Seller and Buyer or any of 
their Affiliates, including, to the extent applicable, any Entity designated 
to hold the Shares, shall take all such necessary action.

     Section 5.3. Further Assurances.  Raytheon, Seller and Buyer agree that, 
from time to time, whether before or after the Closing, each of them will 
execute and deliver such further instruments of conveyance and transfer and 
take such other action as may be reasonably required or desirable to carry 
out the purposes and intent of this Agreement, including (i) allocating 
rights and obligations under Contracts and other arrangements, if any, 
relating to business of Raytheon and its Affiliates other than the Company, 
on the one hand, and relating to the Company on the other, (ii) transferring 
assets to the Company or Buyer, and (iii) entering  into any service or other 
sharing agreements on a mutually acceptable arm's-length basis that may be 
necessary to assure a smooth and orderly transition. In case at any time 
after the Closing Date, any further action is necessary or desirable to carry 
out the purposes of this Agreement, the proper officers and directors of each 
party to this Agreement shall take all such necessary or desirable action.

     Section 5.4. Conduct of Business. From the date hereof through the 
Closing, except as disclosed on Schedule 5.4 hereto or otherwise provided for 
in, or contemplated by, this Agreement, and, except as consented to or 
approved by Buyer in writing (which consent shall not be unreasonably 
withheld or delayed), Raytheon and Seller covenant and agree that:

     (a)  Each of Raytheon and Seller shall, and shall cause the Company to, 
use reasonable efforts to operate the Semiconductor Division Business in the 
ordinary and usual course in all material respects in accordance with past 
practices, and neither Raytheon nor any of its Affiliates will enter into any 
Contract with the Company except with Buyer's consent;

     (b)  except in the ordinary course of business or as required by Law, 
Contract or the terms of a Benefit Plan existing on the date hereof, the 
Company shall not hereafter (and Raytheon and Seller shall not hereafter 
cause the Company to) (i) increase the base compensation of, or enter into 
any new bonus or incentive agreement or arrangement with, any of the senior 

                                       26
<PAGE>

management employees employed by the Company; (ii) pay or agree to pay any 
pension, retirement allowance or other employee benefit to any Buyer 
Employee, whether past or present not otherwise required by Contract or under 
any employee benefit plan in effect on the date hereof; (iii) enter into any 
express new employment, severance, consulting or other compensation agreement 
with any Buyer Employee; or (iv) commit itself to any pension, profit 
sharing, deferred compensation, group insurance, severance pay, retirement or 
other employee benefit plan, fund or similar arrangement in addition to those 
in effect on the date hereof and intended exclusively for Buyer Employees, or 
amend or commit itself to amend any of such plans or similar plans intended 
for the benefit of Raytheon's employees generally if the effect thereof would 
exclusively benefit Buyer Employees, funds or similar arrangements in 
existence on the date hereof.

     (c)  The Company shall not (i) cancel or compromise, except in the 
ordinary course of business consistent with past practice, any debts owed to 
it, (ii) waive or release any rights of material value, (iii) close any 
plants or any other material facilities or (iv) except for purposes of 
transferring Cash and liquidating intercompany accounts, declare any dividend 
or make any distribution with respect to its stock.

     (d)  The Company shall not (i) sell, transfer, distribute as a dividend 
in kind or otherwise dispose of any material asset (other than inventory in 
the ordinary course of business consistent with past practice), (ii) create 
or permit to exist any new material security interest, lien or encumbrance on 
its assets, or (iii) except in the ordinary course of business, enter into 
any joint venture, partnership or other similar arrangement or form any other 
new material arrangement for the conduct of its business or (iv) except in 
the ordinary course of business, purchase any asset.

     (e)  On or as soon as reasonably practicable after the Closing, Buyer 
shall cause the Company shall obtain and utilize with respect to its 
operations a new EPA identification number (and to the extent required, new 
State and local identification numbers) for the generation of Hazardous 
Substances disposed of on or after the Closing Date.

     Section 5.5. Preservation of Business. From the date hereof to the 
Closing Date, subject to the terms and conditions of this Agreement, Raytheon 
and Seller shall, and shall cause the Company to, use reasonable efforts (i) 
to keep available to the Company and Buyer the services of the Buyer 
Employees and (ii) to preserve the good will of customers and others having 
business relations with the Company.

     Section 5.6. Public Announcements.  From the date hereof to the Closing 
Date, Raytheon and Buyer will consult with each other before issuing, or 
permitting any agent or Affiliate to issue, any press releases or otherwise 
making or permitting any agent or Affiliate to make, any public statements 
with respect to this Agreement and the transactions contemplated hereby, and, 
except as may be required by Law or any listing agreement with any securities

     Section 5.7  Use of Raytheon Name.  (a)  From and after the Closing, 
except for purposes of announcing Buyer's acquisition of the Company or 
responding reasonably to inquiries with respect thereto, and except as set 
forth in Section 5.7(b) hereto, Buyer and its Affiliates shall not use or 
permit the use of the names or marks "Raytheon", "Raytheon Semiconductor", 
"RTN", or any Trademark of Raytheon (not constituting Company IP) or any 
Affiliate of Raytheon, any name or mark incorporating the foregoing, or any 
Trademark confusingly similar thereto, nor shall Buyer use or permit the use 
of such names and marks in connection with the operation or disposition of 
the Company or the proceeds thereof; provided, however, that (i) for a period 
of 120 days from the Closing Date, Buyer may make use of promotional and 
sales literature and packaging materials in existence at Closing, provided 
that such literature and materials are stickered or otherwise marked to 
indicate the change of ownership; (ii) for a period of no longer than six 
months from the Closing Date, Buyer may use the Raytheon Marks (defined 
below) on qualified packaging for semiconductor devices, as long as (A) the 
qualified packaging is made from dies existing at Closing which contain one 
or more of the Raytheon Marks, (B) the purchase orders and promotional 
material associated with the sale of semiconductor devices with such 
packaging are clearly marked to show that the devices are manufactured by 
Buyer and (C) Buyer uses its best efforts to promptly design and implement 
re-qualified packaging which does not contain the Raytheon Marks; and (iii) 
nothing in this Section 5.7 shall require the amendment of any Contracts nor 
limit, where relevant, any accurate and complete statement of facts 
concerning ownership of the Company prior to the Closing in any Action or in 
any filing with a Governmental Authority.  Immediately prior to Closing, 
Raytheon may and, to the extent Raytheon has not previously done so, 
immediately after Closing, Buyer shall, cause the Company to change its name.

     (b)  Notwithstanding anything to the contrary contained in Section 
5.7(a) above, from and after the Closing, the Company and Buyer shall have 
the non-exclusive, royalty-free right to use the trademarks "Raytheon" and 
"RTN" (the "Raytheon Marks") solely on semiconductor devices manufactured by 
the Company using Mask Works constituting Assets that incorporate Raytheon 
Marks provided that such semiconductor devices shall conform with Raytheon's 
quality standards.  Buyer will assist Raytheon in maintaining control over 
the quality of the semiconductor devices bearing the Raytheon Marks, and will 
provide specimens of the semiconductor devices to Raytheon upon request.  
Buyer agrees that the semiconductor devices sold by it bearing the Raytheon 
Marks shall be of no less than the same quality as semiconductor devices sold 
by the Company under the Raytheon Marks at Closing.  In addition, Buyer may 
use such Raytheon Marks to the extent that they currently exist on 
specifications, drawings or similar documents referring to such semiconductor 
devices solely for internal use by the Company.

     (c)  Buyer acknowledges that (i) Raytheon is the owner of all right, 
title, and interest in and to the Raytheon Marks, whether alone or in 
combination with other words or designs and Buyer shall not use the Raytheon 
Marks except as expressly authorized by this Agreement and (ii) after 
Closing, it will not and will not permit the Company to (A) take any action 
which would interfere with Raytheon's registration and/or use of the Raytheon 
Marks throughout the world; (B) take any action which would diminish or 
dilute the distinctiveness or validity of the 

                                       28
<PAGE>

Raytheon Marks; (C) challenge Raytheon's ownership of the Raytheon Marks 
and/or registrations therefor; or (D) attempt to register the Raytheon Marks 
or any mark confusingly similar thereto, alone or in combination with other 
words or designs, as a Trademark in its own name anywhere in the world. After 
Closing, Buyer shall cause or shall cause the Company to notify Raytheon of, 
but neither Buyer nor the Company shall be required to defend the Raytheon 
Marks against, infringement claims or Actions, except that Buyer shall 
provide reasonable assistance to Raytheon in connection with steps taken by 
Raytheon to protect the Raytheon Marks, including, but not limited to signing 
any registered user document or other documents required by any Trademark 
Office or other Governmental Authority.

     (d)  After the Closing, Buyer and the Company will assume all risk with 
respect to their use of the Raytheon Marks.  Buyer shall indemnify Raytheon 
and its Affiliates, and their respective employees, officers and directors 
and hold them harmless from and against any claims, damages, judgments, 
losses and expenses, including reasonable attorney's fees, that arise out of 
any claim, threat of litigation or litigation relating to or arising from 
Buyer's or the Company's use of the Raytheon Marks as provided hereunder.

     Section 5.8. Performance of Company Obligations to Raytheon.  Buyer 
agrees from and after the Closing Date to perform and fulfill (or cause to be 
performed and fulfilled) all Scheduled Contracts, existing as of the Closing 
Date, between the Company and Raytheon or any of its Affiliates.

     Section 5.9  Non-Infringement.  Raytheon agrees that neither itself nor 
its Affiliates will, in connection with the Company's conduct of the 
Semiconductor Division Business, assert against Buyer, or its Affiliates, any 
claims for infringement of (i) any Patent, Copyright, or Mask Work which on 
the Closing Date it owns or under which it has a right to grant a License 
without obligation or accounting to others, or (ii) any of the foregoing 
which may later issue on an application owned by Raytheon and pending on the 
Closing Date.

     Section 5.10.  Buyer's Warranty Obligation.  (a)  Buyer covenants and 
agrees that it will cause the Company to honor fully and perform diligently 
all of the Company's product warranty, guaranty and product return 
obligations, express or implied, which arise from or are related to products 
manufactured or services provided prior to the Closing Date by the 
Semiconductor Division or the Company in the ordinary course of business, 
including, with respect to products manufactured for or services provided to 
Raytheon or any Affiliate of Raytheon (other than the Company), provided that 
neither Buyer nor the Company shall have responsibility or liability for any 
such obligations constituting Retained Liabilities as set forth in paragraph 
(iv) of the definition of Retained Liabilities.

     (b)  From and after the Closing Date, Buyer and the Company shall 
indemnify and hold harmless Raytheon from and against any and all Covered 
Liabilities (as defined in Section 11.2 hereof), suffered, incurred by or 
asserted, directly or indirectly, against Raytheon by reason or arising out 
of the covenants set forth in Section 5.10(a) hereof. Claims for breaches of 

                                       29
<PAGE>

covenant of Buyer in Section 5.10(a) hereof may be asserted until 60 days 
after the running of the applicable statute of limitations.

     Section 5.11.  Patent Indemnification. (a) Subject to the limitations 
set forth in this Section 5.11, for the three (3) year period beginning on 
the Closing Date, Raytheon shall indemnify, save and hold harmless Buyer and 
the Company, their Affiliates and for each such Entity their respective 
officers, directors, employees, agents, distributors and users of Company 
Product from and against money damages (including royalties) and/or costs 
awarded arising out of any claims by any third party that the design, 
development, making, having made, use, offer for sale, import, package or 
sale of Company Products by Company infringes any patent issued prior to the 
Closing Date in any country in which the allegedly infringing Company Product 
had been made, used or sold prior to Closing, including those patent 
infringement liabilities identified in Schedule 3.5(d) as Assumed 
Liabilities; provided, however, that such indemnification shall not apply to 
a Company Product if the infringement of a third party's patent would have 
been avoided but for a post-Closing change in manufacturing, design or 
packaging of a Company Product, or but for a change in the combination of 
products with which a Company Product is sold or offered for sale.

     (b)  Upon its receipt of a claim giving rise to a claim for indemnity 
under this Section 5.11, including receipt by it of any notification, 
communication, demand, assertion, claim, action, judicial proceeding, 
administrative proceeding, or other proceeding by any third party that Buyer 
or the Company infringes or has misappropriated such a third party's patent, 
Buyer or the Company will give prompt written notice thereof to Raytheon.  
Buyer's or the Company's failure to notify Raytheon promptly of a claim will 
relieve Raytheon of its obligations under this Section 5.11 only if the 
failure has an Adverse Effect on Raytheon's ability to defend or settle that 
claim, and such failure shall only affect Raytheon's obligations with respect 
to that claim.  Raytheon shall promptly address all claims received from 
Buyer or the Company.  Raytheon shall act in good faith in evaluating a 
settlement of a claim and shall consider the following factors in the 
evaluation:  (i) the validity of the claim, (ii) the monetary limitations of 
the indemnity under this Section 5.11, (iii) the effect of the claim's being 
upheld in litigation upon the Company's business, and (iv) the mutual desire 
of the parties to minimize the expense of the indemnity.

     (c)  The indemnity set forth in Section 5.11 shall apply for the 
enforceable life of the asserted patent with respect to any claims filed 
prior to the expiration of the three year period set forth in Section 5.11(a).

     (d)  With respect to any claim which Raytheon is called upon to 
indemnify Buyer and the Company under the terms of this Section 5.11, 
Raytheon shall have the exclusive control of the defense of such suit and all 
negotiations relative to the settlement thereof.  Buyer and the Company shall 
provide all reasonable information and assistance, at Raytheon's sole 
expense, as Raytheon may request, including, if commercially reasonable, 
redesigning the Company's or Buyer's products to make them non-infringing.  
The commercial reasonableness of a redesign of a product includes, without 
limitation, the retention of all performance features that materially affect 
the marketability of the product, the lack of any material effect on the 
Company or Buyer's 

                                       30
<PAGE>

ability to obtain orders and to obtain and retain customers for the product, 
and the avoidance of any material increased manufacturing costs.  Raytheon 
shall be permitted to settle such claims, upon reasonable prior notice to, 
and after consultation with, Buyer and the Company, at its sole expense, 
provided neither Buyer nor the Company shall have any obligation for future 
expense or payment and provided that the settlement agreement shall not 
result in any requirement that Buyer or the Company cease, alter (except for 
a redesign provided for by this Section 5.11(d)) or curtail the 
manufacturing, importation, marketing or sale of any product.  Buyer and the 
Company shall have the right, but not the obligation, to participate in such 
legal proceedings with counsel of its own selection and its own expense.  
Buyer and the Company agree that Raytheon shall be authorized in the 
settlement of such claims to grant licenses under Patents that are Company IP 
or Raytheon Licensed IP, provided that Buyer and the Company receive from the 
licensee of such patents a reciprocal patent license of comparable weight and 
scope.

     (e)  Raytheon's liability under this Section 5.11 (including all third 
party costs and out-of-pocket expenses incurred by it exclusive, however, of 
any internal Raytheon manhour costs (salaries plus applicable mark-ups for 
fringes and overhead) for the time its employees spent on the matter) shall 
in no event exceed ten million dollars ($10,000,000.00); provided, however, 
that if this liability limit will be exceeded by virtue of any proposed 
settlement, Raytheon shall not make such a settlement without the prior 
written consent of Buyer and the Company provided that Buyer and the Company 
shall be responsible for and shall assume all costs in excess of said limit 
of liability and provided that Buyer shall not unreasonably withhold its 
consent to any proposed settlement.

     (f) The indemnity provided in this Section 5.11 shall not apply if the 
claimed infringement is the result of the Buyer's breach of any obligation 
under any License.

     Section 5.12.  Absence of Debt.  Seller and Raytheon covenant to Buyer 
that the Company has no outstanding debt obligations (including without 
limitation letters of credit or surety obligations) as of the date hereof and 
will have no such debt obligations as of the Closing Date. 

     Section 5.13.  Noncompetition.  Raytheon agrees, on behalf of Raytheon 
and the Affiliates of Raytheon (excluding independently trusteed benefit 
plans, the "Raytheon Group"), that for a period of three (3) years after the 
date hereof (the "Restricted Period"), no member of the Raytheon Group will 
engage directly or indirectly in competition with the Company, whether 
individually or as a consultant, partner, owner or stockholder of an Entity, 
in the business of selling silicon semiconductor devices manufactured or sold 
by the Semiconductor Division Business or the Company (the "Restricted 
Business").  Notwithstanding the foregoing, nothing herein shall prohibit any 
member of the Raytheon Group from (a) owning, directly or indirectly, less 
than ten percent (10%) of any class of securities listed on a national 
securities exchange or traded publicly in the over-the-counter market, (b) 
directly or indirectly acquiring a business which engages in the Restricted 
Business if such business is twenty percent (20%) or less (measured by net 
revenues) of a larger business acquired by a member of the Raytheon Group, 
provided that Raytheon shall not make any Raytheon Licensed IP available to 
such business, (c) 

                                       31
<PAGE>

acquiring a business which engages in the Restricted Business if such 
business is more than twenty percent (20%) but less than fifty percent (50%) 
(measured by net revenues) of a larger business acquired by a member of the 
Raytheon Group, provided that (i) such member of the Raytheon Group places 
such competitive business for sale promptly after its acquisition and uses 
commercially reasonable efforts to complete such sale within the Restricted 
Period and (ii) Raytheon shall not make any Raytheon Licensed IP available to 
such business, (d) continuing to produce and sell those products now being 
produced and sold by members of the Raytheon Group (including within the 
foregoing all products that were under development as of the date hereof), 
except those silicon semiconductor devices that have substantially similar 
specifications to those manufactured by the Company, and (e) continuing any 
business acquired in connection with Raytheon's acquisition of the defense 
industry businesses of Texas Instruments Incorporated  and Hughes Electronics 
Corporation.

     Section 5.14. License Agreement; Delivery of Files.  On the Closing 
Date, the Company and Raytheon will enter into an Intellectual Property 
Assignment and License Agreement in the form attached hereto as Exhibit 5.14 
and Raytheon shall deliver to the Company the file histories for the 
Intellectual Property identified in Schedule 3.5(a) which is being 
transferred to the Company pursuant to Intellectual Property Assignment and 
License Agreement identified in this Section 5.14.

     Section 5.15. Transition Services Agreement.  On the Closing Date, the 
Company and Raytheon will enter into a Transition Services Agreement in the 
form attached hereto as Exhibit 5.15.

     Section 5.16. Retention Obligations.  While the obligations associated 
with the "stay-on" arrangements constitute Retained Liabilities, it is 
acknowledged by the parties that Buyer will pay any costs associated with 
such arrangements and will be reimbursed by Raytheon after such payments have 
been made.

     Section 5.17.  Performance of Seller's Obligations.  Raytheon shall 
cause Seller to perform Seller's obligations hereunder.

     Section 5.18.  Survey.  Raytheon may cause a survey of the land at the 
Mountain View Facility to be conducted, and upon completion and delivery 
thereof to Buyer, so much of Raytheon's and Buyer's representation and 
warranty in Section 3.4(a) as applies to encroachments with respect to the 
Mountain View Facility (other than encroachments that Adversely Affect the 
use or value thereof) shall terminate.  The cost of the survey will be borne 
equally by Raytheon and Buyer.   

     Section 5.19.  Intellectual Property Claims.  In the event that any 
claim is made against Buyer or Company with respect to any design, 
development, making, having made, using, offering for sale, importing, 
exporting, or selling of Company Products as a result of the fact that 
Raytheon failed to identify in Schedule 3.5(c) any license for Third Party 
Licensed IP and that, as a consequence thereof, failed to request the 
required consents to transfer such license rights to the 

                                       32                                       
<PAGE>

Company, then in such case Raytheon shall, subject to the limit of liability 
set forth in Section 5.11(e), indemnify, save and hold harmless Buyer and the 
Company from and against any money damages (including royalties) and/or costs 
awarded arising out of any such claim to the extent that such amounts are in 
excess of the license fees and royalties which would have been payable had 
the license been identified and transferred.  The limit of liability under 
Section 5.11(e) is an aggregate limit for claims arising under both Section 
5.11 and this Section.  Raytheon shall have no liability if it requests and 
obtains the required consents with retroactive application and Raytheon shall 
have no liability, resulting from a licensor's refusal to grant the consents 
when requested to do so.

           Employees, Employee Benefits and Other Transitional Matters
                                       
     Section 6.1.  Hiring Employees; Comparable Benefits.  (a) Except as 
provided hereafter with respect to certain employees to be terminated, Buyer 
will cause the Company to continue in employment as of the Closing Date (or, 
in the case of employees within clause (iii), as of the date of their return 
to active employment) but makes no commitment with respect to any period 
following the Closing Date  (i) all employees on the Company's active payroll 
on the Closing Date, (ii) all persons who are subject to outstanding 
employment offers from the Company at Closing and (iii) any Semiconductor 
Employee not on the Company's active payroll on the Closing Date on account 
of an approved leave of absence or short-term disability leave (but excluding 
those employees on long-term disability leave) if such employee returns to 
active employment with the Company immediately upon the conclusion of any 
such leave of absence or within the period required by Law (all such 
employees being "Buyer Employees"). Not less than 10 days before the Closing 
Date Raytheon or Seller shall cause the Company to terminate up to 20 
individuals (the "Terminated Semiconductor Employees") (whose names Buyer 
shall have the option to provide to Seller or Raytheon not less than 15 days 
before the Closing Date and which list of names Raytheon and Seller shall 
have the right to approve) who but for such termination would be Buyer 
Employees as of the Closing Date; provided that Raytheon or Seller shall not 
be responsible for the costs of such terminations. Schedule 6.1(a) lists all 
Buyer Employees.   All employment of Buyer Employees after Closing and for 
the 365 day period following the Closing shall be for pay and benefits no 
less favorable in the aggregate than the pay and benefits in effect at 
Closing.  Such employment and the benefits to be provided to the Employees 
shall recognize the date of hire and time of service with Raytheon and/or the 
Company for vesting and eligibility but not benefit accrual purposes unless 
inconsistent with another provision of this Article.

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

                                       33
<PAGE>

     Section 6.2.  Medical Benefits and Retirement Plans.  Commencing as of 
the Closing Date, Buyer shall provide the Buyer Employees and dependents and 
beneficiaries thereof (the "Eligible Individuals") medical and dental benefit 
coverage as well as the opportunity to participate in Buyer's "401(k)" plan. 
Buyer Employees shall be entitled to roll over to Buyer's 401(k) plan 
distributions they may receive from any "401(k)" or other profit-sharing plan 
maintained by Raytheon or any Affiliate of Raytheon.

     Section 6.3.  Investment Plans.  Raytheon will retain all liability and 
responsibility for the disposition of interests under the Raytheon Savings 
and Investment Plan (the "RAYSIP Plan") and the Raytheon Stock Ownership Plan 
(the "RAYSOP Plan" and, together with the RAYSIP Plan, the "Investment 
Plans") with respect to those employees (or their beneficiaries) of the 
Company who, as of the Closing Date, are participants in either of the 
Investment Plans.  No such participant will be eligible to make any 
contributions to the RAYSIP Plan, and Raytheon will not be obligated to make 
any contribution with respect to any such participant in either Investment 
Plan, with respect to compensation earned by such employees on or after the 
Closing Date.   Raytheon agrees that it will cause the accounts in RAYSIP of 
all such participants to be fully vested as of the Closing Date.

     Section 6.4.  Pension Plans.  Raytheon shall retain all liability and 
responsibility for any benefit or other liabilities accrued under any defined 
benefit pension plan, as defined in Section 3(35) of ERISA, maintained by 
Raytheon.  Buyer shall have no obligation with respect to any defined benefit 
plan, nor any obligation to establish any such plan. 

     Section 6.5.  Incentive Plans.  Attached as Schedule 6.5(a) is a 
description of Raytheon's incentive plans (the "Incentive Plans") in which 
employees of the Company participate.  The Company will maintain adequate 
accruals on the Closing Balance Sheet for such plans.

     Section 6.6.  Indemnification.

     (a)  Raytheon agrees to indemnify Buyer and the Company, and hold them 
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) arising out of the employment, or failure to 
employ, any individual by Raytheon or any Affiliate for any period ending on 
or before the Closing Date or arising out of any employee benefit plan or 
arrangement maintained by Raytheon or any Affiliate.

     (b)  Buyer agrees to indemnify Raytheon and its Affiliates other than 
the Company, and hold them 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) arising out of 
the employment, or failure to employ any individual (except for the costs 
assumed pursuant to Section 6.1 and excluding any Terminated Semiconductor 
Employee), for any period after the Closing Date or arising out of any 
employee benefit plan or arrangement maintained by Buyer.

                                       34
<PAGE>

     (c)  The indemnities provided for in Sections 6.6(a) and 6.6(b) hereof 
shall expire 60 days after the running of the applicable statute of 
limitations.

     Section 6.7.   Access to Books and Records.  As soon as practicable 
after the Closing Date, Buyer shall receive from Raytheon (i) such pertinent 
data or information as Buyer may reasonably require to determine the Buyer 
Employees' accrued benefits under the Raytheon Retirement Plans, (ii) such 
information concerning each Buyer Employee's period of employment with 
Raytheon and/or the Company as Buyer may reasonably require to determine 
service for eligibility and benefit accrual purposes, and (iii) such 
information concerning the terms of the Benefit Plans and concerning each 
Buyer Employee's benefit utilization under welfare benefit plans as Buyer may 
reasonably require to comply with this Agreement.     

     Section 6.8.   Exclusive Benefit.  This Article VI shall operate 
exclusively for the benefit of Buyer and Seller and not for the benefit of 
any other Person including, without limitation, any current, former or 
retired employee of Buyer or Seller.

     Section 7.1.  Tax Indemnification by Seller and Raytheon.  (a)  Seller 
and Raytheon shall be liable for, and shall hold Buyer and the Company and 
any successor corporations thereto or Affiliates thereof harmless from and 
against, the following Taxes with respect to the Company:

          (i)  any and all Income Taxes for any taxable period ending (or 
deemed, pursuant to Section 7.3 hereof, to end) on or before the Closing Date 
due or payable by the Company including, without limitation, any and all 
Income Taxes resulting from the 338(h)(10) Elections; and

          (ii) to the extent not reserved for on the Adjusted Closing Balance 
Sheet, any Other Taxes payable with respect to Tax Returns filed or required 
to be filed (taking into account extensions), or otherwise properly 
accruable, on or before the Closing Date.

     (b)  Seller and Raytheon shall also be liable for, and shall hold Buyer 
and the Company and any successor corporations thereto or Affiliates hereof 
harmless from and against, all Taxes with respect to the operations of Seller 
or its Affiliates, other than those operations conducted by the Company and 
its subsidiaries, including any several liability of the Company under 
Treasury Regulations section 1.1502-6 or under any comparable or similar 
provision under state, local or foreign laws or regulations, and from and 
against any liability for Taxes with respect to any gain realized by Seller 
upon the sale of the Company.

     Section 7.2.  Tax Indemnity by Buyer.  Buyer shall be liable for, and 
shall hold Seller harmless from and against, the following Taxes with respect 
to the Company and its subsidiaries or Affiliates:  (i) any and all Income

Date, due or payable by the Company or by Seller, (ii) any and all Other 
Taxes (other than Taxes described in Section 7.1 hereof for which Seller is 
liable) for all taxable periods (whether beginning before, on or after the 
Closing Date), and (iii) any and all Other Taxes not incurred in the ordinary 
course of business attributable to the acts or omissions of Buyer, Buyer's 
Affiliates or the Company after the Closing on the Closing Date.

     Section 7.3.  Allocation of Certain Taxes.

     (a)  Buyer and Seller agree that if the Company is permitted but not 
required under applicable state or local Income Tax laws to treat the Closing 
Date as the last day of a taxable period, Buyer and Seller shall treat such 
day as the last day of a taxable period.

     (b)  Any Taxes for a taxable period beginning before the Closing Date 
and ending after the Closing Date with respect to the Company shall be 
apportioned for purposes of Sections 7.1 and 7.2 hereof between Seller and 
Buyer based on the actual operations of the Company, as the case may be, 
during the portion of such period ending on the Closing Date and the portion 
of such period beginning on the date following the Closing Date, and for 
purposes of the provisions of Sections 7.1, 7.2, 7.3 and 7.5, each portion of 
such period shall be (whether or not it is in fact a taxable period); 
provided, however, that real property and personal property taxes shall be 
allocated on a per diem basis; provided, further, that to the extent 
estimated Income Taxes have been paid prior to the Closing Date with respect 
to a taxable period beginning before the Closing Date and ending after the 
Closing Date, Seller's liability with respect thereto shall be reduced by 
that amount; provided further, that if such payment of estimated Income Taxes 
exceeds Seller's liability as calculated pursuant to this Section 7.3., Buyer 
shall promptly pay Seller the amount of such excess.  Upon timely notice from 
Buyer, Seller shall pay to Buyer at least ten (10) days prior to the date any 
payment for Income Taxes as described in this Section 7.3 is due, Seller's 
share of such Income Taxes as described in this Section 7.3.

     (a)  Seller shall prepare and file or shall cause the Company to prepare 
and file all Returns with respect to Income Taxes for periods ending on or

and file, subject in the case of any such Returns for Income Taxes or Returns 
for Other Taxes that reflect a tax liability greater than which entered into 
the computation of the accrual set forth on the Adjusted Closing Balance 
Sheet to Seller's review and approval, all Returns for taxable periods 
beginning before the Closing Date and ending after the Closing Date, and all 
other Returns for which Seller does not have filing responsibility pursuant 
to Section 7.4(a) hereof.

     (c)  Buyer agrees that it will not, and will not permit the Company to, 
except to the extent contrary to Law, take any position in the Returns 
referred to in clause (b) above 

                                       36

periods beginning on or after the Closing Date.

     (c)  Seller shall be entitled to any refunds or credits of Other Taxes 
for which Seller is liable pursuant to Section 7.1(b) hereof.  Buyer and the 
Company shall be entitled to any refunds or credits of Other Taxes not 
referred to in the preceding sentence attributable to or arising in any 
taxable period (whether beginning before or after the Closing Date).

     (d)  Buyer agrees that if as the result of any audit adjustment made by 
any taxing authority with respect to a taxable period ending on or prior to 
the Closing Date, Buyer or the Company receives a Tax Benefit, then Buyer 
shall pay to Seller the amount of such Tax Benefit (on an after-tax basis) 
within 15 days of filing the Return in which such Tax Benefit is realized or 
utilized.

     (e)  Seller agrees that if as the result of any audit adjustment made by 
any taxing authority with respect to a taxable period ending on or before the 
Closing Date, Buyer, the Company or any of its Affiliates suffers a Tax 
Detriment, then Seller shall pay to Buyer the amount of such Tax Detriment 
(on an after-tax basis) within 15 days of the filing of the Return in which 
such Tax Detriment is realized or incurred.

     (f)  Buyer shall cause the Company promptly to forward to Seller or to 
reimburse Seller for any refunds or credits due Seller (pursuant to the terms 
of this Article VII)  after receipt thereof, and Seller shall promptly 
forward to Buyer (pursuant to the terms of this Article VII) or reimburse 
Buyer for any refunds or credits due Buyer after receipt thereof.

     (g)  Buyer and the Company agree that, with respect to any Income Tax, 
the Company shall not carry back any item of loss, deduction or credit which 
arises in any taxable period ending after the Closing Date ("Subsequent 
Loss") into any taxable period ending on or before the Closing Date.  If a 
Subsequent Loss with respect to any Income Tax is carried back into any 
taxable period ending on or before the Closing Date, Seller shall be entitled 
to any refund or credit of Taxes realized as a result thereof.

     (a)  Seller shall prepare and submit to Buyer, no later than three 
months after the Closing Date, 1997 and, if applicable, 1998 blank tax return 
workpaper packages.  Buyer shall, and shall cause the Company to prepare 
completely and accurately and submit to Seller within three months of 
receipt, all such information as Seller shall reasonably request in such tax 
return workpaper packages. 

     (b)  As soon as practicable, but in any event within thirty (30) days 
after Seller's request, from and after the Closing Date, Buyer shall provide 
Seller with such cooperation and shall deliver to Seller such information and 
data concerning the pre-Closing operations of the Company and make available 
such knowledgeable employees of the Company and its subsidiaries and 
Affiliates as Seller may reasonably request, including providing the 
information and data required by Seller's customary tax and accounting 
questionnaires, in order to enable Seller to complete and file all Returns 
which it may be required to file with respect to the operations and business 
of the Company and its subsidiaries and Affiliates through the Closing Date 
or to respond to audits by any Taxing Authorities with respect to such 
operations and to otherwise enable Seller to satisfy its internal accounting, 
tax and other legitimate requirements.  Such cooperation and information 
shall include provision of powers of attorney for the purpose of signing 
Returns and defending audits and promptly forwarding copies of appropriate 
notices and forms or other communications received from or sent to any Taxing 
Authority which relate to the Company, and providing copies of all relevant 
Returns, together with accompanying schedules and related workpapers, 
documents relating to rulings or other determinations by any Taxing Authority 
and records concerning the ownership and tax basis of property, which Buyer 
or the Company may possess.  Each of Buyer and the Company shall make its 
respective employees and facilities available on a mutually convenient basis 
to provide explanation of any documents or information provided hereunder.

     (c)  For a period of three (3) years after the Closing Date, Buyer 
shall, and shall cause the Company to, retain all Returns, books and records 
(including computer files) of, or with respect to the activities of, the 
Company for all taxable periods ending on or prior to the Closing Date.  
Thereafter, Buyer shall not dispose of any such Returns, books or records 
unless it first offers such Returns, books and records to Seller and Seller 
fails to accept such offer within sixty (60) days of its being made.

     Buyer and Seller shall cooperate in the preparation of all Returns 
relating in whole or in part to taxable periods ending on or before the 
Closing Date that are required to be filed after such date.

     (d)  Whenever any Taxing Authority asserts a claim, makes an assessment, 
or otherwise disputes the amount of Taxes for which Seller is liable, Buyer 
shall promptly inform Seller (provided that failure to provide such notice 
shall not impair Buyer's rights except to the extent that Seller demonstrates 
that it has been damaged thereby), and Seller shall have the right to control 
any resulting meetings, conferences or proceedings and to determine whether 
and when to settle any such claim, assessment or dispute to the extent such 
proceedings or determinations affect the amount of Taxes for which Seller is 
liable.

                                       38

     (e)  If Buyer or the Company fails to provide any information requested 
by Seller in the time specified herein, or if no time is specified pursuant 
to this Section 7.6, within a reasonable period, or otherwise fails to do any 
act required of it under this Section 7.6, then Buyer shall be obligated, 
notwithstanding any other provision of this Agreement, to indemnify Seller 
and Buyer shall so indemnify Seller and hold Seller harmless from and against 
any and all costs, claims or damages, including all Taxes or deficiencies 
thereof, payable as a result of such failure.

     Section 7.7.  Purchase Price.  Buyer and Seller agree that the 
consideration provided for pursuant to this Agreement is being paid solely to 
acquire the Shares and neither party will (or will permit any Affiliate to) 
report or treat any part of such consideration as allocable to anything other 
than payment for the Shares.

     Section 7.8.  Tax Sharing Agreements.  Any Tax Sharing Agreement between 
the Company and Raytheon, Seller or any other Person is terminated as of the 
Closing Date and shall have no further effect for any taxable year (whether a 
current year, a future year or a past year).

     Section 7.9.  Elections and Forms.

     (a)  With respect to Seller's sale of the Shares hereunder, Seller and 
Buyer shall, at the election of Buyer, jointly make all available Section 
338(h)(10) Elections in accordance with applicable Tax Laws and as set forth 
herein.  Buyer and Seller agree to report the transfers under this Agreement 
consistent with the Section 338(h)(10) Elections, and shall take no position 
contrary thereto unless required to do so by applicable Tax Laws pursuant to 
a Determination.

     (b)  Buyer shall be responsible for the preparation and filing of all 
Section 338 Forms in accordance with applicable Tax Laws and the terms of 
this Agreement.  Seller shall execute and deliver or shall cause to be 
executed or delivered to Buyer such documents or forms as are reasonably 
requested and are required by any Tax Laws properly to complete the Section 
338 Forms, at least twenty (20) days prior to the date such Section 338 Forms 
are required to be filed.

     (c)  Buyer and Seller agree that they shall use their best efforts to 
enter into an agreement (the "Allocation Agreement") prior to the Closing 
Date concerning the computation of the Aggregate Deemed Sale Price (as 
defined under applicable Treasury Regulations) of the Assets and the 
allocation of such Aggregate Deemed Sale Price among the Assets.  Such 
Allocation Agreement shall be in accordance with Law.  Buyer and Seller shall 
agree that they shall use their best efforts to revise the Allocation 
Agreement to the extent necessary to reflect the differences, if any, between 
the Balance Sheet and the Closing Date Balance Sheet no later than sixty (60) 
days before the last date on which the Section 338(h)(10) Election may be 
filed.  If, sixty days before the last date on which the Section 338(h)(10) 
Election may be filed, Buyer and Seller have not adopted or revised the 
Allocation Agreement as described above, any disputed aspects of the 
Allocation Agreement or such revision shall be resolved before the last date 
on which the Section 338(h)(10) Election may be filed by a "big six" 
accounting firm 

                                       39

mutually agreed upon by Buyer and Seller having no material relationship with 
either Buyer or Seller.  The costs, expenses and fees of such accounting firm

accordance with the allocations contained in the Allocation Agreement in any 
relevant Returns or similar filings.

                              Environmental Matters 
                                       
     Section 8.1. Environmental Liabilities. 

     (a)  The parties acknowledge that the Mountain View Facility is listed 
on the National Priorities List and has been the subject of Remediation by 
Raytheon with oversight by the United States Environmental Protection Agency 
("EPA"). Raytheon shall retain all responsibility and liability following 
Closing, with such consultants and contractors as it may select in its sole 
discretion, for dealing with EPA and undertaking and completing Remediation 
of conditions at or originating from the Mountain View Facility which arose 
prior to the Closing Date or were created by Releases of Hazardous Substances 
that first occurred prior to the Closing Date, to the extent required by 
Environmental Law or any Order, taking into consideration the current 
industrial use of the Mountain View Facility (the "Mountain View 
Environmental Liabilities").  Raytheon shall retain all rights under 
insurance policies and all rights to recover from responsible parties with 
respect to the Mountain View Environmental Liabilities.  Raytheon shall bear 
no responsibility for any conditions which may arise on or after the Closing 
Date as a result of any Post-Closing Release of Hazardous Substances by Buyer 
or any third party (except Raytheon's consultants or contractors or any 
Person acting for, on behalf of or at the direction of Raytheon, including, 
without limitation, in connection with the performance of the Remediation of 
the Mountain View Facility ("Raytheon Parties")), provided that any leaking, 
leaching, migration or similar movement of Hazardous Substances which existed 
in soil or ground water prior to the Closing Date shall not be considered a 
Release by Buyer except to the extent such is exacerbated by activities or 
negligent omissions of Buyer or any third party (other than any Raytheon 
Parties) on or after the Closing Date.

     (b)  In connection with such Remediation of the Mountain View 
Environmental Liabilities by Raytheon, Raytheon shall conduct all Remediation 
required by EPA or any other 

                                       41
<PAGE>

Governmental Authority with jurisdiction (subject to Raytheon's right to 
contest any such requirement by appropriate proceedings), and Buyer shall, 
upon prior written notice, provide Raytheon, its consultants and contractors 
access to the Mountain View Facility and shall permit them to install, 
operate and maintain remedial treatment systems and to conduct all other 
Remediation which Raytheon determines to be necessary or appropriate.  Buyer 
will cause any successor owners of the Facility to afford Raytheon the same 
rights to access and to conduct Remediation (which access shall only be to 
the extent necessary to conduct the Remediation and shall terminate upon the 
completion of the Remediation), and Buyer agrees to record an appropriate 
acknowledgment of such rights in the Registry of Deeds upon Raytheon's 
request.  Raytheon shall use commercially reasonable efforts not to interfere 
unreasonably with Buyer's operation of the Company (where reasonableness is 
determined by the conduct of a reasonably prudent person responsible for both 
the operations of the business and the conduct of the Remediation) and 
Raytheon shall indemnify and hold harmless Buyer Indemnified Parties (as 
defined in Section 11.2) for any damage to the Mountain View Facility and 
against any liability to third persons to the extent such damage or liability 
is caused by Raytheon's Remediation; provided, however, as a condition to 
such indemnity, that upon the request of Raytheon, the Buyer Indemnified 
Party first assigns, subrogates or otherwise effectively transfers to 
Raytheon its rights against the Persons causing such damage or liability.  
Raytheon agrees to reasonably cooperate with the Buyer's reasonable plans for 
the future use of the Mountain View Facility by relocating or modifying 
equipment used in connection with the Remediation; provided, however, that 
Buyer will be responsible for the cost of such relocation or modification.

     (c)  In addition to the foregoing, from and after the Closing Date, 
Raytheon shall indemnify, defend and hold Buyer Indemnified Parties (as 
defined in Section 11.2) harmless from and against any and all Covered 
Liabilities asserted against or incurred or suffered by Buyer Indemnified 
Parties arising out of or related to:  (i) environmental conditions first 
occurring, existing or arising prior to the Closing Date arising out of or 
resulting from the Release of Hazardous Substances in, on, under, from, or at 
the Mountain View Facility and any real property formerly (but not currently) 
owned, operated or leased by the Company or any of its predecessors except to 
the extent such is exacerbated by activities or negligent omissions of Buyer 
or any third party (other than any Raytheon Parties) on or after the Closing 
Date or (ii) the off-site transportation, disposal, recycling, treatment or 
storage prior to the Closing Date of Hazardous Substances generated by the 
Company or Raytheon in connection with the Semiconductor Division Business 
prior to the Closing Date.

     (d)  Notwithstanding the foregoing, nothing contained in this Section 
8.1 shall be interpreted to waive any claims which Raytheon may have against 
Buyer in the absence of this transaction and Raytheon does not indemnify or 
hold harmless Buyer with respect to any Covered Liabilities for which Buyer 
would be responsible in the absence of this transaction.

     Section 8.2.  Indemnities by Buyer.  Buyer shall indemnify and hold 
harmless Raytheon against all Covered Liabilities asserted against or 
incurred or suffered by Raytheon arising out of or relating to the Release 
first occurring on or after the Closing Date of any Hazardous Substance in, 
on, under or from any portion of a facility owned, operated or leased by the 
Company after 

                                       42
<PAGE>

the Closing Date (except in each case from an off-site source and provided 
that any leaking, leaching, migration or similar movement of Hazardous 
Substances which existed in soil or ground water prior to the Closing Date 
shall not be considered a Release by Buyer except to the extent such is 
exacerbated by activities or negligent omissions of Buyer or anyone other 
than Raytheon Parties post-Closing on the Company's property); provided, 
however, that Buyer may, at its election, control the defense and, if 
required, Remediation in connection with any such Covered Liabilities.  
Except as set forth in Section 8.1(b), Buyer shall also indemnify and hold 
harmless Raytheon against (a) all claims and liabilities caused by any 
refusal by Buyer or successor owners to allow Remediation by Raytheon or any 
unreasonable interference with the conduct, management or control of 
Remediation by Raytheon and (b) all claims and liabilities arising from or 
related in any way to the Remediation by Buyer or any third party, including 
any Governmental Authority, or additional Remediation required of Raytheon, 
in connection with or as a result of any changes to the existing use of the 
Mountain View Facility.

     Section 8.3.  Remediation for Releases after Closing.  If any 
Remediation required by Environmental Law with respect to Releases of 
Hazardous Substances at, on, in or under any portion of the Mountain View 
Facility is required in part by Releases before the Closing Date and in part 
by Releases first occurring on or after the Closing Date (provided that any 
leaking, leaching, migration or similar movement of Hazardous Substances 
which existed in soil or ground water prior to the Closing Date shall in no 
event be considered a post-Closing Date Release), the costs for such cleanup 
or other response shall be divided between Raytheon and Buyer according to 
their respective degree of responsibility in connection with such Releases.  
To determine Buyer's portion of the costs for such cleanup or other response, 
Raytheon shall deliver to Buyer its good faith estimate of the allocation of 
responsibility.  Within 30 days after Raytheon's delivery of such estimate, 
Buyer shall be entitled to provide notice to Raytheon that it is of the view 
that Raytheon's allocation of responsibility was not accurate and shall 
provide Buyer's good faith estimate of the allocation of responsibility in 
reasonable detail.  Thereupon, Raytheon and Buyer shall meet to resolve their 
differences concerning such allocation.  If Raytheon and Buyer cannot agree 
within 30 days of the date of such notice, such allocation of fault shall be 
promptly resolved by submitting, at either party's request, such dispute to 
final and binding arbitration.  The Arbitrator shall be a retired Judge from 
JAMS/End Dispute ("JAMS") selected by the JAMS office in Boston, 
Massachusetts.  The arbitration location shall be decided by the parties 
jointly, or if no agreement is reached, the arbitration shall be held at a 
location selected by JAMS.  Each party shall bear its own expenses and will 
share equally in the arbitrator's fees and related expenses, provided that 
once an arbitration judgment is entered, the prevailing party shall be 
entitled to recover attorneys' and or expert fees and related costs.  The 
arbitrator will determine what discovery, if any, is appropriate.  Judgment 
on the award rendered by the arbitrator may be entered in a court having 
competent jurisdiction.   The judgment awarded by the Arbitrator shall be 
final, binding and nonappealable.

     Section 8.4.  OSHA Matters.

     (a)  Set forth on Schedule 8.4 hereto is a list of certain conditions 
and operations observed by Buyer at the Mountain View Facility and separately 
with respect to each, the 

                                       43
<PAGE>

sections under the Occupational Safety and Health Act, as amended ("OSHA"), 
and each of the specific regulations adopted pursuant thereto deemed 
applicable by Buyer to each such condition or operation.  Raytheon has 
reviewed Schedule 8.4 and considers that no actions are necessary to conform 
such conditions and operations with the requirements of such sections of OSHA 
and such regulations as are set forth for each listed item on Schedule 8.4 
hereto. 

     (b)  From and after the date hereof and until Raytheon takes such 
actions as are required to bring any item listed on Schedule 8.4 hereto into 
reasonable conformity (to the extent such item was not already in reasonable 
conformity) with the sections of OSHA and regulations thereunder cited on 
Schedule 8.4 hereto, or until such item is in reasonable conformity 
therewith, Raytheon shall indemnify and hold harmless Buyer and the Company 
from and against any and all Covered Liabilities (as defined in Section 11.2 
hereof), suffered, incurred by or asserted, directly or indirectly, against 
Buyer or the Company by reason or arising out of an item identified on 
Schedule 8.4 hereto not in reasonable conformity with OSHA and the 
regulations thereunder.  Claims for indemnity by Buyer in this Section 8.4 
may be asserted until 60 days after the running of the applicable statute of 
limitations.  The indemnity provided pursuant to this paragraph shall be void 
and of no effect unless Buyer grants Raytheon reasonable access to the 
Mountain View Facility for purposes of remedying or alleviating any condition 
or operation listed on Schedule 8.4.  Buyer agrees that when requested by 
Raytheon to acknowledge that a condition or operation specified in Schedule 
8.4 has been brought into or is in reasonable conformity with the sections of 
OSHA and the regulations thereunder specified on Schedule 8.4, it will do so 
promptly after reasonable inquiry.

     Section 8.5  Wastewater Treatment.  Raytheon agrees that, without the 
prior consent of Buyer (which consent shall be granted at Buyer's 
discretion), it will not accept or treat pollutants, including wastewater or 
groundwater, from any property other than the Mountain View Facility except 
for pollutants from other properties the treatment of which is (i) within the 
existing capacity of the treatment facilities of the Mountain View Facility 
and footprint, and (ii) which are either (A) currently being transported for 
treatment to the Mountain View Facility via existing pipeline, or (B) 
contemplated to be transported for treatment to the Mountain View Facility 
from the properties located at 365 and 415 East Middlefield Road along a 
pipeline routing proposed by Raytheon, provided, however, that, Raytheon 
shall indemnify and hold harmless Buyer Indemnified Parties for Covered 
Liabilities suffered, incurred by or asserted, directly or indirectly, 
against Buyer Indemnified Parties by reason or arising out of such acceptance 
or treatment of wastewater and groundwater from such other properties; and 
with respect to clause (ii)(B), within 90 days of the date hereof, Buyer may 
propose routing the pipeline in a manner convenient to it (subject to a 
maximum cost of $450,000), and Raytheon will construct at its expense the 
pipeline in accordance with such routing.

                   Conditions of Buyer's Obligation to Close

Agreement (which for purposes of this paragraph shall be read as though none 
of them contain any Adverse Affect, Change or Effect or other materiality 
qualifier individually or in the aggregate) shall be true and correct on and 
as of the Closing Date with the same effect as though such representations 
and warranties had been made on and as of such date (except for 
representations and warranties that speak as of a specific date or time, 
which need only be true and correct as of such date or time), except where 
the failure of the representations and warranties in the aggregate to be true 
and correct in all respects would not have an Adverse Effect on the Company.

Date in order to consummate the transactions contemplated hereby and to 
transfer the Licenses and Contracts contemplated hereby shall have been

                   Conditions to Seller's Obligation to Close
                                           
     Seller's obligation to consummate the Stock Purchase is subject to the

conditions:

     Section 10.1. Representations, Warranties and Covenants of Buyer. (a) 
The representations and warranties of Buyer contained in this Agreement 
(which for purposes of this paragraph shall be read as though none of them 
contain any Adverse Affect, Change or Effect or other materiality qualifier 
individually or in the aggregate) shall be true and correct on and as of the 
Closing Date with the same effect as though such representations and 
warranties had been made on and as of such date (except for representations 
and warranties that speak as of a specific date or time, which need only be 
true and correct as of such date or time), except where the failure of the 
representations and warranties in the aggregate to be true and correct in all 
respects would not have an Adverse Effect on Buyer or Buyer and its 
subsidiaries, taken as a whole.

     (b)  Buyer shall have performed in all material respects each obligation 
and agreement and shall have complied in all material respects with each 
covenant to be performed and complied with by it hereunder at or prior to the

     (c)  Seller shall receive at or prior to the Closing a certificate as to

     Section 10.2. Filings: Consents: Waiting Periods. All waiting periods 
applicable under the HSR Act shall have expired or been terminated, and all 
registrations, filings, applications, notices, consents, approvals, Orders, 
qualifications and waivers required to be obtained or made as of the Closing 
Date in order to consummate the transactions contemplated hereby shall have 
been filed, made or obtained, except for such registrations, filings, 
notices, consents, approvals, Orders, qualifications and waivers the lack of 
which would not reasonably be expected to have an Adverse Effect on Buyer or 
Buyer and its subsidiaries, taken as a whole.

     Section 10.3. No Injunction. At the Closing Date, there shall be no 
Order of any nature of any Governmental Authority of competent jurisdiction

                                  Article XI.
                           Survival: Indemnification
                                           
     Section 11.1. Survival Periods.  Except as provided in Section 11.4, all 
representations and warranties contained or made in, or in connection with, 
this Agreement or in any Schedule, or any certificate, document or other 
instrument delivered in connection herewith, shall survive the Closing for a 
period of eighteen months.

     Section 11.2. Indemnification by Seller. From and after the Closing 
Date, Raytheon shall indemnify and hold harmless Buyer, the Company, their 
Affiliates, each of their directors, officers, employees and agents, and each 
of the heirs, executors, successors, transferees and assigns of any of the 
foregoing (collectively, the "Buyer Indemnified Parties") from and against 
any and all damages, claims, losses, expenses, costs, obligations and 
liabilities, including without limitation liabilities for all reasonable 
attorneys', accountants', and experts' fees and expenses including those 
incurred to enforce the terms of this Agreement (collectively, "Covered 
Liabilities"), suffered, incurred by or asserted, directly or indirectly, 
against the Buyer Indemnified Parties by reason or arising out of (i) any 
breach of any representation or warranty, covenant or agreement of Raytheon 
or Seller contained herein (each of which for purposes of this paragraph 
shall be read as though none of them contains any Adverse Affect, Change or 
Effect or other materiality qualifier), or (ii) any Retained Liability; 
provided, however, that, except for a breach of any representation or 
warranty in Section 3.15, Raytheon shall not be required to indemnify the 
Buyer Indemnified Parties with respect to any claim for indemnification 
pursuant to clause (i) of this Section 11.2 unless and until the aggregate 
amount of all claims against Raytheon under this Section 11.2 exceeds 
$1,000,000 and then only to the extent such aggregate amount exceeds such 
amount, and; provided, further, that, except for a breach of any 
representation or warranty in Section 3.15, in no event shall Raytheon be 
required to pay or otherwise be liable for an amount in excess of $40,000,000 
with respect to claims made under clause (i) of this Section.

     Section 11.3. Indemnification by Buyer.  From and after the Closing 
Date, Buyer shall indemnify and hold harmless Raytheon, its Affiliates, each 
of their directors, officers, employees and agents, and each of the heirs, 
executors, successors and assigns of any of the foregoing (collectively, the 
"Raytheon Indemnified Parties") from and against any and all Covered 
Liabilities suffered, incurred by or asserted, directly or indirectly, 
against by the Raytheon Indemnified Parties by reason or arising out of (i) 
any breach of any representation or warranty, covenant or agreement of Buyer 
contained herein (each of which for purposes of this paragraph shall be read 
as though none of them contains any Adverse Affect, Change or Effect or other 
materiality qualifier), or (ii) any Assumed Liability; provided, however, 
that Buyer shall not be required to indemnify the Raytheon Indemnified 
Parties with respect to any claim made for indemnification pursuant to clause 
(i) of this Section 11.3 unless and until the aggregate amount of all claims 
against Buyer under this Section 11.3 exceeds $1,000,000 and then only to the 
extent such aggregate amount exceeds such amount, and; provided, further, 
that in no event shall

                                       47
<PAGE>

Buyer be required to pay or otherwise be liable for an amount in excess of 
$40,000,000 with respect to claims made under clause (i) of this Section.

     Section 11.4.  Time Limit on Certain Indemnification Claims.  Claims by 
Buyer Indemnified Parties for breaches of the representations and warranties 
of Raytheon and Seller in Section 3.1 hereof or by Raytheon Indemnified 
Parties for breaches of the representations and warranties of Buyer in 
Section 4.1 hereof in each case relating to corporate formation, may be 
asserted indefinitely.  Claims for breaches of all other representations and 
warranties in Sections 3.1 and 4.1, and for breaches of representations and 
warranties in Sections 3.11, 3.15 and 3.16 may be asserted until 60 days 
after the running of the statutes of limitations applicable to contracts, 
ERISA, CERCLA and the Code, respectively. Claims for breach of Raytheon's and 
Seller's representation and warranty in Section 3.4(a) insofar as it relates 
to the Mountain View Facility (other than with respect to encroachments, as 
to which Section 5.18 is applicable) shall not survive the Closing, and prior 
to Closing may be asserted only in accordance with Section 9.1(d) as a 
condition to Buyer's obligation to consummate the Stock Purchase.  Time 
periods for indemnities provided for in ancillary agreements will be governed 
by the provisions of such ancillary agreements.

     Section 11.5.  Indemnification Procedures. (a) If any indemnified party 
receives notice of the assertion of any Third-Party Claim with respect to 
which an indemnifying party is obligated under this Agreement to provide 
indemnification, such indemnified party shall give such indemnifying party 
written notice thereof (together with a copy of such Third-Party Claim, 
process or other legal pleading) promptly after becoming aware of such 
Third-Party Claim; provided, however, that the failure of any indemnified 
party to give notice as provided in this Section 11.5 shall not relieve any 
indemnifying party of its obligations under this Section 11.5, except to the 
extent that such indemnifying party is actually prejudiced by such failure to 
give notice. Such notice shall describe such Third-Party Claim in reasonable 
detail.

      (b) An indemnifying party, at such indemnifying party's own expense and 
through counsel chosen by such indemnifying party (which counsel shall be 
reasonably acceptable to the indemnified party), may elect to defend any 
Third-Party Claim. If an indemnifying party elects to defend a Third-Party 
Claim, then, within ten (10) business days after receiving notice of such 
Third-Party Claim (or sooner, if the nature of such Third-Party claim so 
requires), such indemnifying party shall notify the indemnified party of its 
intent to do so, and such indemnified party shall cooperate in the defense of 
such Third-Party Claim (and pending such notice and assumption of defense, an 
indemnified party may take such steps to defend against such Third-Party 
Claim as, in such indemnified party's good-faith judgment, are appropriate to 
protect its interests). Such indemnifying party shall pay such indemnified 
party's reasonable out-of-pocket expenses incurred in connection with such 
cooperation. Such indemnifying party shall keep the indemnified party 
reasonably informed as to the status of the defense of such Third-Party 
Claim.  After notice from an indemnifying party to an indemnified party of 
its election to assume the defense of a Third-Party Claim, such indemnifying 
party shall not be liable to such indemnified party under this Section 11.5 
for any legal or other expenses subsequently incurred by such indemnified 
party in connection with the defense thereof other than those expenses 
referred to in

                                       48
<PAGE>

the preceding sentence; provided, however, that such indemnified party shall 
have the right to employ one law firm as counsel, together with a separate 
local law firm in each applicable jurisdiction ("Separate Counsel"), to 
represent such indemnified party in any action or group of related actions 
(which firm or firms shall be reasonably acceptable to the indemnifying 
party) if, in such indemnified party's reasonable judgment at any time, 
either a conflict of interest between such indemnified party and such 
indemnifying party exists in respect of such claim, or there may be defenses 
available to such indemnified party which are different from or in addition 
to those available to such indemnifying party and the representation of both 
parties by the same counsel would be inappropriate, and in that event (i) the 
reasonable fees and expenses of such Separate Counsel shall be paid by such 
indemnifying party (it being understood, however, that the indemnifying party 
shall not be liable for the expenses of more than one Separate Counsel 
(excluding local counsel) with respect to any Third-Party Claim (even if 
against multiple indemnified parties)), and (ii) each of such indemnifying 
party and such indemnified party shall have the right to conduct its own 
defense in respect of such claim. If an indemnifying party elects not to 
defend against a Third-Party Claim, or fails to notify an indemnified party 
of its election as provided in this Section 11.5 within the period of ten 
(10) business days described above, the indemnified party may defend, 
compromise, and settle such Third-Party Claim and shall be entitled to 
indemnification hereunder (to the extent permitted hereunder); provided, 
however, that no such indemnified party may compromise or settle any such 
Third-Party claim without the prior written consent of the indemnifying 
party, which consent shall not be unreasonably withheld or delayed. 
Notwithstanding the foregoing, the indemnifying party shall not, without the 
prior written consent of the indemnified party, (i) settle or compromise any 
Third-Party Claim or consent to the entry of any judgment which does not 
include as an unconditional term thereof the delivery by the claimant or 
plaintiff to the indemnified party of a written release from all liability in 
respect of such Third-Party Claim, or (ii) settle or compromise any 
Third-Party Claim in any manner that would reasonably be expected to have a 
material adverse effect on the indemnified party.

     Section 11.6. Certain Limitations. (a) The amount of any Covered 
Liabilities for which indemnification is provided under this Agreement shall 
be net of any amounts actually recovered by the indemnified party from third 
parties (including amounts actually recovered under insurance policies, but 
only to the extent any recovered insurance proceeds exceed costs of 
collecting such proceeds and premium increases, whether retrospective or 
prospective, that are certified by the underwriter to result from the claim 
for such proceeds) with respect to such Covered Liabilities. Any indemnifying 
party hereunder shall be subrogated to the rights of the indemnified party 
upon payment in full of the amount of the relevant indemnifiable loss. An 
insurer who would otherwise be obligated to pay any claim shall not be 
relieved of the responsibility with respect thereto or, solely by virtue of 
the indemnification provision hereof, have any subrogation rights with 
respect thereto. If any indemnified party recovers an amount from a third 
party in respect of an indemnifiable loss for which indemnification is 
provided in this Agreement after the full amount of such indemnifiable loss 
has been paid by an indemnifying party or after an indemnifying party has 
made a partial payment of such indemnifiable loss and the amount received 
from the third party exceeds the remaining unpaid balance of such 
indemnifiable loss, then the indemnified party shall promptly remit to the 

                                       49
<PAGE>

indemnifying party the excess of (A) the sum of the amount theretofore paid 
by such indemnifying party in respect of such indemnifiable loss plus the 
amount received from the third party in respect thereof, less (B) the full 
amount of such Covered Liabilities.

     (b)  Any indemnity payment made under this Agreement shall be treated by 
Buyer and Seller as an adjustment to the  Purchase Price, and Seller and 
Buyer agree not to take any position inconsistent therewith for any purpose.

     (c)  Claims indemnifiable hereunder that are asserted within the periods 
permitted under Sections 11.1 and 11.4 shall, notwithstanding the passage of 
time beyond such periods, remain indemnifiable until enforced or compromised 
and satisfied in favor of, or withdrawn by, the indemnitee.  The limitations 
on liability for indemnification set forth in the proviso clauses of Sections 
11.2 and 11.3 shall not apply to any Covered Liability resulting from (i) a 
breach of representation or warranty contained herein committed with the 
knowledge of Raytheon or Buyer, as the case may be or (ii) an intentional 
breach of a covenant within the control of Raytheon or Buyer, as the case may 
be. 

     Section 11.7. Exclusivity of Indemnification. This Article XI shall not 
limit any right of indemnification for Employee Benefit Matters (for which 
Article VI is applicable), of indemnification for Tax Matters (for which 
Article VII is applicable), of indemnification for Environmental Matters (for 
which Article VIII is applicable) or of indemnification for intellectual 
property matters (for which Article V and ancillary agreements are 
applicable). The limitations contained in this Article XI relate solely to 
indemnification and nothing contained in this Agreement shall limit in any 
manner the rights of any party hereto to assert any claim against any other 
party hereto for breach of any term or condition of this Agreement.

                                 Article XII.
                                  Termination

      Section 12.1. Termination. This Agreement may be terminated at any time 
prior to the Closing by:

     (a)  The mutual written consent of Raytheon and Buyer; or

     (b)  Either Raytheon or Buyer if the Closing has not occurred by the 
close of business on December 31, 1997 (which date shall be extended until 
two (2) days after expiration of the notice period under the HSR Act or 
receipt by each of notice of clearance under the HSR Act), and if the failure 
to consummate the Stock Purchase on or before such date did not result from 
the failure by the party seeking termination of this Agreement to fulfill any 
undertaking or commitment provided for herein that is required to be 
fulfilled prior to Closing.

     (c)   Raytheon, provided that neither it nor Seller is then in breach of 
any of its obligations hereunder, if Buyer fails to perform in any material 
respect 

                                       50
<PAGE>

any covenant in this Agreement when performance thereof is due or Buyer shall 
have breached in any material respect any of the representations or 
warranties contained in this Agreement and does not cure the failure or 
breach within thirty (30) business days after Raytheon delivers written 
notice thereof; or

     (d)  Buyer, provided it is not then in breach of any of its obligations 
hereunder, if Raytheon or Seller fails to perform in any material respect any 
covenant in this Agreement when performance thereof is due or Raytheon or 
Seller shall have breached in any material respect any of the representations 
and warranties contained in this Agreement and does not cure the failure or 
breach within thirty (30) business days after Buyer delivers written notice 
thereof.

     Section 12.2. Procedure and Effect of Termination. In the event of 
termination of this Agreement by either or both of Raytheon and Buyer 
pursuant to Section 12.1, written notice thereof shall forthwith be given by 
the terminating party to the other party hereto, and this Agreement shall 
thereupon terminate and become void and have no effect, and the transactions 
contemplated hereby shall be abandoned without further action by the parties 
hereto, except that the provisions of Sections 5. l(b) and 13.4 hereof shall 
survive the termination of this Agreement; provided, however, that such 
termination shall not relieve any party hereto of any liability for any 
breach of this Agreement. If this Agreement is terminated as provided herein, 
all filings, applications and other submissions made pursuant to Sections 3.8 
and 4.3 hereof shall, to the extent practicable, be withdrawn from the agency 
or other persons to which they were made.

                                 Article XIII.
                                 Miscellaneous
                                           
     Section 13.1.  Counterparts. This Agreement may be executed in two or 
more counterparts, all of which shall be considered one and the same 
agreement, and shall become effective when one or more counterparts have been 
signed by each of the parties and delivered to the other party.

     Section 13.2. Governing Law; Consent to Jurisdiction. This Agreement 
shall be governed by and construed in accordance with the laws of the 
Commonwealth of Massachusetts without reference to the choice of law 
principles thereof. Buyer, Raytheon and Seller consent to and hereby submit 
to the exclusive jurisdiction of any state or federal court located in the 
Commonwealth of Massachusetts in connection with any action, suit or 
proceeding arising out of or relating to this Agreement, and each of the 
parties hereto irrevocably waives, to the fullest extent permitted by law, 
any objection which it may now or hereafter have to the laying of the venue 
of any such proceeding brought in such a court and any claim that any such 
proceeding brought in such a court has been brought in an inconvenient forum.

     Section 13.3. Entire Agreement. This Agreement (including agreements 
incorporated herein) and the Schedules and Exhibits hereto contain the entire 
agreement between the parties with respect to the subject matter hereof and 
there are no agreements, understandings, representations or warranties 
between the parties other than those set forth or referred to herein.

     Section 13.4.  Expenses. Except as set forth in this Agreement, whether 
the Stock Purchase is or is not consummated, all legal and other costs and 
expenses incurred in connection with this Agreement and the transactions

expenses; provided that Buyer shall pay all transfer taxes, if any, relating 
to the transfer of the Shares.

arbitration location shall be decided by the parties jointly or, if no 
agreement is reached, the arbitration shall be held in Boston, Massachusetts. 
 Each party shall bear its own expenses and will share equally in 
arbitrator's fees and related expenses provided that once an arbitration 
judgment is entered, the prevailing party shall be entitled to recover 
attorneys' and/or expert fees and related costs as damages.  The arbitrator 
will determine what discovery, if any, is appropriate.  Judgment on the award 
rendered by the arbitrator may be entered in a court having competent 
jurisdiction.  In no event will any award include consequential, exemplary, 
multiple or punitive damages notwithstanding any Law entitling a party to 
claim such.

     Section 13.13. Specific Performance. The parties hereto each acknowledge 
that, in view of the uniqueness of the subject matter hereof, the parties 
hereto would not have an adequate remedy at law for money damages in the 
event that this Agreement were not performed in accordance with its terms, 
and therefore agree that the parties hereto shall be entitled to specific 
enforcement of the terms hereof in addition to any other remedy to which the 
parties hereto may be entitled at law or in equity.

     Section 13.14. Remedies Cumulative. Except as otherwise provided in 
Article 11, all rights, powers and remedies provided under this Agreement or 
otherwise available in respect hereof at law or in equity shall be cumulative 
and not alternative, and the exercise or beginning of the exercise of any 
thereof by any party shall not preclude the simultaneous or later exercise of 
any other such right, power or remedy by such party.  Notwithstanding the 
foregoing, however, no party hereto shall be liable for and no remedy under 
this Agreement or at law or in equity shall include, provide for or permit 
the payment of multiple, exemplary, punitive or consequential damages or any 
equitable equivalent thereof or substitute therefor, and the burden shall be 
on the party claiming loss to show actual loss in the amount claimed.

4.2
 
4.2.1 Raytheon shall, and shall use reasonable efforts to cause its Affiliates
      and their respective directors, officers, employees, agents and
      representatives ("Raytheon Representatives") to, hold in strict confidence
      and not to use any Company Know-How in its possession or control except as
      otherwise provided below. Notwithstanding the foregoing, Raytheon and
      Raytheon Representatives may use and disclose such information for audit,
      accounting and tax purposes, and for purposes of fulfilling disclosure and
      reporting obligations but only to the extent as in the opinion of 
      Raytheon's counsel is required by law or regulation and also for such 
      other purposes as may be expressly authorized by this Agreement or by 
      the Acquisition Agreement.
 
4.2.2 Raytheon shall not, and shall use reasonable efforts to cause the Raytheon
      Representatives not to, release or otherwise disclose such Company Know-
      How to any third party except Raytheon Representatives who have a need to 
      know such and except as necessary for the purposes authorized above 
      provided that any such authorized recipient shall be bound by appropriate
      obligations of confidentiality which are consistent with those contained 
      in this Section 4.2 except that provided in the case of disclosure 
      required by law or regulation the disclosure may be made pursuant to 
      the protection afforded to confidential information under the applicable 
      law or regulation.
 
4.2.3 Raytheon shall, and shall use reasonable efforts to cause the Raytheon  
      Representatives, to protect any such Company Know-How to prevent 
      the unauthorized use, disclosure, or publication of such Company 
      Know-How. The restrictions set forth above in this Section 4.2 shall 
      not apply (a) to the extent that disclosure is compelled by judicial or 
      administrative process, or in the opinion of Raytheon's counsel, by 
      other requirements of law, or (b) to any information which Raytheon can 
      show was (i) publicly available prior to the Closing Date or thereafter 
      becomes publicly available without any violation of this Agreement on 
      the part of Raytheon or the Raytheon Representatives or (ii) became 
      available to Raytheon or to any Raytheon Representative from a Person 
      other than Company, who, to the best of Raytheon's knowledge, was not 
      subject to any continuing legally binding obligation to Company to keep 
      such information confidential, (iii) was disclosed to others without 
      restriction by Company or by any party who received such Company 
      Know-How from Company, or (iv) was independently developed by any 
      Raytheon Representative without use of or reliance on Company Know-How.
 
4.2.4 Raytheon's obligation under this Section 4.2 shall in any event expire ten
      years from the Closing Date. Raytheon's obligations under this Section 4.2
      with respect to the protection of Company Know-How shall be to use the 
      same degree of care, but no less than reasonable care, to prevent the
      unauthorized use or disclosure of such Company Know-How as it uses with
      respect to the protection of its own information of like importance, and 
      in no event shall Raytheon or Raytheon Representatives be liable for (i)
      inadvertent disclosure provided that the aforementioned degree of care has
      been used and provided that, upon discovery of any such inadvertent
      disclosure, Raytheon shall endeavor to prevent any further inadvertent
      disclosure or (ii) for any special, indirect, consequential, incidental,
      multiple or punitive damages.

    Section 4.1 above, the Company shall forthwith notify Raytheon, and, upon
    the request and at the expense of Raytheon, shall cooperate with the
    Raytheon in contesting such a disclosure. Except in connection with failure

    counsel and the like as necessary in the ordinary course of business in
    connection with the exercise of the Company's rights under this Agreement,
    (ii) sublicensees or transferees pursuant to Sections 3.4 and 3.5, or (iii)

    subject to appropriate written obligations of confidentiality at least as
    restrictive as those contained herein.

    telecopier to the telecopy number set forth above.
 
5.5 NO WAIVER--Failure of a party to insist upon strict adherence to any term of

    Agreement. Any waiver must be in writing in order to be effective.
 
5.6 SUCCESSORS AND ASSIGNMENT--This Agreement shall inure to the benefit of, and
    be binding upon, Raytheon and Company and may not be assigned in whole or in

5.7  NO THIRD PARTY BENEFICIARIES--Nothing herein is intended to, or shall be
     construed to, confer upon any Person not a party hereto any rights or
     benefits hereunder.
 
5.8  COUNTERPARTS--This Agreement may be executed in two counterparts, each of

     thereof to any party hereto or set of circumstances shall, in any

     unenforceable, such term or provision shall only be ineffective as to such
     jurisdiction, and only to the extent of such invalidity or 
     unenforceability, without invalidating 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.
 
5.10 NO FURTHER REQUIREMENTS--Raytheon shall not be required by anything
     contained in this Agreement to file in any country an application, mask
     work, registration, copyright or patent, or to secure any mask work

     registration, copyright or patent, to maintain the mask work registration,
     copyright or patent in force.

     the contrary in the Purchase Agreement, Company assumes all risk and
     liability arising from its use of or reliance on Intellectual Property
     rights assigned or licensed to it by Raytheon pursuant to this Agreement.

     Raytheon or an Affiliate of Raytheon which is not a Licensed Product or of
     any service of Raytheon or an Affiliate of Raytheon which is not a foundry
     service for making Licensed Products, provided, however, that, in addition
     to the above and to any rights granted under Section 3.6 above, the Company
     shall not assert any Company IP which is listed in Exhibit 1 for the period
     of this agreement against Raytheon any Affiliate of Raytheon or their
     customers or distributors with respect to the performance, use, offer for
     sale, import, export, making (including making for Raytheon or an Affiliate
     of Raytheon by others on an OEM or subcontract basis) of any product of

5.13 DISCLAIMER OF WARRANTIES--Raytheon makes no representation, warranty or
     indemnification to Company pursuant to this Agreement. All representations,
     warranties and indemnifications, if any, made by Raytheon to Company
     regarding the subject matter of this Agreement shall be solely as set forth
     in the Purchase Agreement and without limiting the general applicability of
     the foregoing, nothing in this Agreement shall be construed as:
 
         (i) a warranty or representation by Raytheon or Company as to the 
             validity or scope of any intellectual property rights;
 
        (ii) a warranty or representation by Raytheon or Company that any 
             manufacture, sale, lease, import, use or other disposition of 
             products or services after the Closing Date made pursuant to the 
             intellectual property rights assigned, licensed or sublicensed 
             hereunder will be free from infringement of intellectual 
             property rights of third parties; or
 
       (iii) a requirement of Raytheon or Company to bring or prosecute 
             actions or suits against third parties for infringement or 
             misappropriate of any intellectual property rights assigned or 
             licensed hereunder.
 
5.14 In the event that any third party infringes the Raytheon Patents, Raytheon
     Copyrights or Raytheon Mask Works in connection with Licensed Products and
     such infringement is on a commercial scale which causes detriment to
     Company's business, Raytheon shall give good faith consideration to any
     request from Company that Company be permitted to take action against such
     infringement provided that Raytheon does not, in its sole discretion,
     believe that such action is inconsistent with, or detrimental to, 
     Raytheon's business interests. In the event that Raytheon elects to 
     permit Company to take such action, Raytheon shall permit an action to 
     be brought in its name to the extent required to bring the action and 
     Raytheon shall have a right to participate in such action insofar as 
     Raytheon has an interest and Company will not enter into any settlement 
     agreement relating to the Raytheon Patents, Raytheon Copyrights and 
     Raytheon Mask Works which would jeopardize the scope or validity of the 
     Raytheon Patents, Raytheon Copyrights or Raytheon Mask Works without the 
     express written consent of Raytheon.
