ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

                 On October 5, 1998, Westinghouse Air Brake Company ("WABCO" or
the "Company") acquired from Rockwell Collins, Inc. ("Rockwell") certain
businesses and operations in the United States. The transaction involved a sale
agreement, executed and delivered on August 7, 1998. In the agreement, WABCO
purchased from Rockwell all of the issued and outstanding capital stock of
Technical Service and Marketing, L.L.C., a Delaware limited liability company
("TSM"), and the assets of the Rockwell Railroad Electronics division ("RRE" and
collectively with TSM, the "Business"), which consisted of Mobile Electronics,
Data Communications, and Railcar Electronics.

                 The assets of the Business consist of leased real property
located in Kansas City, Missouri (approximately 30,000 square feet) and Cedar
Rapids, Iowa (approximately 1,000 square feet), as well as manufacturing and
office equipment, inventory, supplies, accounts and notes receivable, advances
and letters of credit, financial, accounting and operating records, commercial
and technical information, contracts, agreements, sale and purchase orders, open
bids, prepaid expenses, deposits and retentions, licenses, franchises, permits,
authorizations and approvals, goodwill, causes of action and other rights of
recovery, warranty claims against unaffiliated third parties and intellectual
property. The Business had approximately 200 employees in October, 1998. Prior
to WABCO's acquisition thereof, such assets had been used in the manufacture and
sale of, among other things, display and positioning systems for use by railroad
locomotive manufacturers, data products and monitoring products for use by
railroads and locomotive manufacturers, and electronic air brake systems for use
by railroads and railcar manufacturers. It is presently anticipated that the
acquired assets will continue in those same uses.

                 The aggregate purchase price for the Business was cash in the
amount of approximately $80 million. The purchase price was arrived at by
negotiation among the parties. To obtain the necessary funds for the
acquisition, on October 5, 1998 the Company entered into (a) an amendment and
restatement of its secured credit agreement with The Chase Manhattan Bank, The
Chase Manhattan Bank Delaware, The Bank of New York and the other financial
institutions named therein which increased the amount available under its
secured credit agreement to $350 million and (b) a $30 million unsecured credit
agreement with the Chase Manhattan Bank, The Bank of New York and the other
financial institutions named therein.

                  (xii) any books, records or other data relating to Seller's
         ownership or operation of the Business that primarily are part of
         Seller's or its Affiliates' (other than TSM) general corporate books
         and records or required by applicable Law to be retained by Seller or
         any of its Affiliates;

                  (xiii) all receivables and other amounts owed to the Business
         by Seller or any of its Affiliates as of the Closing Date;

                  (xiv) any of the rights of Seller or any of its Affiliates
         under this Agreement (or under any other agreement between Seller or
         any of its Affiliates, on the one hand, and Buyer or any of its
         Affiliates, on the other hand, relating to or contemplated by this
         Agreement);

                  (xv) all work in process and production stock and supply

                  (xvi) all rights, causes of action, claims, sums and fees
         arising out of (x) any Retained Assets or (y) any Retained Liabilities.

         (d) Anything contained herein to the contrary notwithstanding, Buyer
expressly acknowledges that the Business does not include, and Seller is not
selling, conveying, assigning, transferring or delivering to Buyer, and Buyer is
not purchasing or acquiring from Seller, any of Seller's right, title and
interest in and to any or all of the assets, rights, contracts, leases and
agreements used in or relating to any of the following businesses of Seller or
its Affiliates: (i) "FleetMaster"; (ii) Integrated Local Governments Systems

existing or future satellite or other communications capability or service
relating to any such business.

         (e) Anything contained herein to the contrary notwithstanding, this
Agreement shall not constitute an agreement to assign any Contract or Permit if
an assignment or attempted assignment of the same without the Consent of the
other party or parties thereto (or, in the case of any Permit, the Governmental
Authority that issued or granted such Permit) would constitute a breach thereof
or not be permitted by Law, or in any way impair the rights of Seller, Buyer or
any of their respective Affiliates thereunder. Seller will, prior to the
Closing, use, and will cause TSM to use, its reasonable best efforts (it being
understood that such efforts shall not include any requirement or obligation of
Seller, TSM or any of their respective Affiliates to pay any consideration
(other than a de minimis amount), or offer or grant any financial
accommodation),



                                      -8-
<PAGE>   13

and Buyer will cooperate in all reasonable respects with Seller and TSM to
obtain all Consents necessary to convey to Buyer the Assets. If any such Consent
is not obtained or if an attempted assignment would be ineffective or would
impair Seller's, TSM's, Buyer's or any of their respective Affiliates' rights
under any such Contract or Permit so that Buyer would not receive all such
rights, then (x) Seller will use its reasonable best efforts (it being
understood that such efforts will not include any requirement or obligation of
Seller or any of its Affiliates to pay any consideration (other than a de
minimis amount), offer or grant any financial accommodation or other benefit or
release any claim or right) to provide or cause to be provided to Buyer, to the
extent permitted by Law, the benefits of any such Contract or Permit and Seller
will promptly pay or cause to be paid to Buyer when received all moneys received
by Seller or any of its Affiliates with respect to any such Contract or Permit,
and (y) Buyer will pay, perform and discharge on behalf of Seller and its
Affiliates all of Seller's and its Affiliates' obligations and liabilities
thereunder in a timely manner and in accordance with the terms thereof.

3.       LIABILITIES TO BE ASSUMED.

         (a) Liabilities to Be Assumed. Subject to the terms and conditions set
forth herein, in consideration for the sale, conveyance, assignment, transfer
and delivery of the Assets to Buyer, on the Closing Date Seller shall assign,
convey and transfer to Buyer, and Buyer shall assume and undertake to pay,
perform and discharge, in a timely manner and in accordance with the terms
thereof, all of Seller's Liabilities arising out of or relating exclusively to

or relating to any Contract (including, without limitation, any warranty
obligation in respect



                                      -9-
<PAGE>   14

hereinafter collectively referred to as the "Assumed Liabilities." 

         (b) Retained Liabilities. Notwithstanding anything contained herein to

obligations of Seller (the "Retained Liabilities") shall be excluded from the
Assumed Liabilities:

                  (i) any Tax Liability of Seller or TSM for any Tax period or
         portion thereof ending on or prior to the Closing Date;

                  (ii) any accrued Liabilities associated with Continued
         Employees under Seller's employee benefit plans described in Section

         benefit plans as contemplated in Section 11(e);

                  (iii) any Liability relating to a Retained Asset;

                  (iv) any Liabilities associated with Retained Employees;

                  (v) that portion of any Liability of Seller of any kind,
         character or description, whether presently in existence or arising
         hereafter, that does not arise out of or relate to the Assets or the
         Business;

                  (vi) all Taxes on any income, gain or profit realized by
         Seller or any of its Affiliates on the disposition of the TSM Shares or

                  (vii) all Liabilities with respect to those incentive
         arrangements described on Schedule 3(b)(vii) with respect to the sale
         of the Business;

                  (viii) all Liabilities for indebtedness for borrowed money;

                  (ix) all Liabilities in respect of payables and other balances
         (including intercompany cash management balances) owed by the Business
         to Seller or any of its Affiliates as of the Closing Date;

                  (x) any Liability or obligation of Seller or any of its
         Affiliates under this Agreement (or under any other agreement 



                                      -10-
<PAGE>   15

         between Seller or any of its Affiliates, on the one hand, and Buyer or
         any of its Affiliates, on the other hand, relating to this Agreement);
         and

                  (xi) all obligations and Liabilities for which Seller is
         expressly made responsible pursuant to this Agreement.

4.       PURCHASE PRICE.

         (a) Initial Purchase Price. In consideration for the sale, conveyance,
assignment, transfer and delivery of (i) the TSM Shares, (ii) the Assets and
(iii) the covenant not to compete of Seller and its Affiliates set forth in
Section 15, at the Closing, Buyer shall (i) pay to Seller, by wire transfer of
immediately available U.S. Dollars to Account No. 102-3474 at Mellon Bank, N.A.,
Pittsburgh, Pennsylvania, an amount equal to EIGHTY MILLION DOLLARS
($80,000,000) ( the "Initial Purchase Price"), and (ii) assume the Assumed
Liabilities. 

         (b) Post-Closing Purchase Price Adjustment. As promptly as is
reasonably practicable, but in any event within ninety (90) days after the
Closing Date, Seller shall deliver to Buyer a statement of combined statement of
net assets of the Business as of the close of business on the day preceding the
Closing Date (the "Closing Statement of Net Assets"). Seller will retain
Deloitte & Touche LLP ("D&T") to audit the Closing Statement of Net Assets and
to render its report thereon stating that the Closing Statement of Net Assets
has been prepared in accordance with the terms of this Section 4(b). Such report
of D&T will be delivered to Buyer together with the Closing Statement of Net
Assets. The date on which the Closing Statement of Net Assets and the report of
D&T are delivered to Buyer is referred to herein as the "Delivery Date." The
Closing Statement of Net Assets shall be prepared by Seller from the books,
accounts and financial records of Seller and TSM relating to the Business. The
Closing Statement of Net Assets and the Final Closing Statement of Net Assets
shall be prepared in accordance with GAAP (except as disclosed in the 



                                      -11-
<PAGE>   16

September 30 Audited Financial Statements), utilizing the accounting practices
and procedures of the Business utilized in the preparation of the September 30
Audited Financial Statements (the "Accounting Practices and Procedures of the
Business"), consistently applied, except that (x) there shall not be additions
to accumulated amortization of goodwill for any period after March 31, 1998; (y)
there shall not be reserves for impairment of long-lived assets (it being
understood that this shall not include normal depreciation or amortization); and
(z) there shall be a reserve in the amount of ONE MILLION TWO HUNDRED FOURTEEN
THOUSAND DOLLARS ($1,214,000), in full satisfaction of Seller's modification
program with respect to certain products, as more fully described on Schedule
4(b)(i) hereto (the "Modification Reserve"); provided, however, that such amount
shall be reduced dollar-for-dollar for amounts actually expended between the
date hereof and the Closing Date with respect to such modification program. In
addition, on or before the seventh day after the date hereof, Buyer shall be
provided with reasonable access to persons in the Business familiar with the
Phase I EABS brake system software upgrade (the "EABS Upgrade"), and Seller and
Buyer shall, in the exercise of their reasonable good faith judgment, determine
whether, under the Accounting Practices and Procedures of the Business, a
reserve for the EABS Upgrade on the Closing Statement of Net Assets would be
appropriate. Notwithstanding the foregoing, it is understood that the amount of
the Modification Reserve shall be adjusted if, on or before the seventh day
after the date of this Agreement, during which period Buyer shall be provided
with reasonable access to persons in the Business familiar with the modification
program and to such other information regarding the modification program as
Buyer may reasonably request, Buyer and Seller in the exercise of their
reasonable good faith judgment determine that an adjustment of such amount is
appropriate. Buyer will cause Seller and D&T to be provided access at all
reasonable times to the personnel, properties, books and records of Buyer and
its Affiliates for such purposes. Without limiting the 



                                      -12-
<PAGE>   17

generality of the foregoing, Buyer will cause such employees of Buyer and its
Affiliates as Seller or D&T shall reasonably request to execute and deliver
representation letters in favor of D&T in connection with their audit of the
Closing Statement of Net Assets and their issuance of a report thereon. 

                  (i) Within forty-five (45) days after the Delivery Date, Buyer
         shall either inform Seller in writing that the Closing Statement of Net
         Assets is acceptable or object to the Closing Statement of Net Assets
         in writing setting forth a specific description of Buyer's objections.
         To be assertable in a notice of objection (a "Notice of Objection"), an
         objection by Buyer with respect to any individual item on or omitted
         from the Closing Statement of Net Assets must assert that the Closing
         Statement of Net Assets was not prepared in accordance with the terms
         of this Section 4(b) with respect to each such item. In addition, the
         requested adjustment for each item must equal or exceed FIFTY THOUSAND
         DOLLARS ($50,000); provided, however, that items for which the
         requested adjustment is less than FIFTY THOUSAND DOLLARS ($50,000) may
         be the basis for a Notice of Objection, if the amount of such items in
         the aggregate equals or exceeds ONE HUNDRED THOUSAND DOLLARS
         ($100,000). 

                  If a Notice of Objection is delivered to Seller within such
         30-day period, then the Closing Statement of Net Assets (as adjusted,
         if necessary) will be deemed to be the Final Closing Statement of Net
         Assets for all purposes on the earlier of (x) the date Seller and Buyer
         resolve in writing all differences they have with respect to the
         Closing Statement of Net Assets or (y) the date the disputed matters
         are resolved in writing by the Unaffiliated Firm. In the event that
         disputed matters are resolved by the Unaffiliated Firm, the Final
         Closing Statement of Net Assets will consist of the applicable amounts
         from the Closing Statement of Net Assets (or amounts otherwise agreed
         to in writing by Seller and 



                                      -13-
<PAGE>   18

         Buyer) as to items that have not been submitted for resolution to the
         Unaffiliated Firm, and the amounts determined by the Unaffiliated Firm
         as to items that were submitted for resolution by the Unaffiliated Firm
         (the "Final Closing Statement of Net Assets"). 

                  (ii) During the 30-day period following the delivery of a
         Notice of Objection, Seller and Buyer will seek in good faith to
         resolve any differences they may have with respect to matters specified
         in the Notice of Objection. If, at the end of such 30-day period,
         Seller and Buyer have not reached agreement on such matters, Seller
         will have 30 days to advise Buyer in writing of Seller's position with
         respect to each of Buyer's proposed adjustments that are in dispute
         (the "Seller's Letter"). Buyer will cause Seller and D&T to be provided
         access at all reasonable times to the personnel, properties, books and
         records of Buyer and its Affiliates to enable Seller to prepare
         Seller's Letter. Promptly following the delivery to Buyer of Seller's
         Letter, Seller and Buyer will jointly engage KPMG Peat Marwick, L.L.P.
         (or, if KPMG Peat Marwick, L.L.P. is unable or unwilling to act in such
         capacity, PricewaterhouseCoopers LLP) (the "Unaffiliated Firm") to
         resolve the matters which remain in dispute with respect to the Closing
         Statement of Net Assets. In connection with such engagement, each of
         Seller and Buyer agrees to execute, if requested by the Unaffiliated
         Firm, a reasonable engagement letter including customary indemnities.
         Promptly after such engagement of the Unaffiliated Firm, Seller or
         Buyer will provide the Unaffiliated Firm with a copy of this Agreement,
         the Closing Statement of Net Assets, the Notice of Objection and the
         Seller's Letter. The Unaffiliated Firm will have the authority to
         request in writing such additional written submissions from either
         Seller or Buyer as it deems appropriate, provided that a copy of any
         such submission will be provided to the other Party at the same time as
         it is provided to the Unaffiliated Firm. Neither Party will make 



                                      -14-
<PAGE>   19

         (nor permit any of its Affiliates to make) any additional submission to
         the Unaffiliated Firm except pursuant to such a written request by the
         Unaffiliated Firm. Neither Party will communicate (nor permit any of
         its Affiliates to communicate) with the Unaffiliated Firm without
         providing the other Party a reasonable opportunity to participate in
         such communication with the Unaffiliated Firm (other than with respect
         to written submissions in response to the written request of the
         Unaffiliated Firm). The Unaffiliated Firm will have 45 days to review
         the documents provided to it pursuant to this Section 4(b)(ii). Within
         such 45-day period, the Unaffiliated Firm will furnish simultaneously
         to both Parties its written determination with respect to each of the
         adjustments in dispute submitted to it for resolution. The Unaffiliated
         Firm will resolve the differences regarding the Closing Statement of
         Net Assets based solely on the information provided to the Unaffiliated
         Firm by the Parties pursuant to the terms of this Agreement (and not
         independent review). The Unaffiliated Firm's authority will be limited
         to resolving disputes with respect to whether the Closing Statement of
         Net Assets was prepared in accordance with the terms of this Section
         4(b) with respect to the individual items on the Closing Statement of
         Net Assets in dispute (it being understood that the Unaffiliated Firm
         will have no authority to make adjustments to any amounts other than
         amounts set forth on the Closing Statement of Net Assets that are in
         dispute). In resolving any disputed item, the Unaffiliated Firm may not
         assign a value to such item greater than the greatest value for such
         item asserted by either Party or less than the smallest value for such
         item asserted by either Party. The decision of the Unaffiliated Firm
         will be, for all purposes, conclusive, non-appealable, final and
         binding upon both Seller and Buyer. The fees of the Unaffiliated Firm
         will be borne by Seller and Buyer in the same proportion that the
         dollar amount of disputed 



                                      -15-
<PAGE>   20

         items lost by a Party bears to the total dollar amount in dispute
         resolved by the Unaffiliated Firm. Each Party will bear the fees, costs
         and expenses of its own accountants and all of its other expenses in
         connection with matters contemplated by this Section 4(b). 

                  (iii) Upon the Closing Statement of Net Assets being deemed
         the Final Closing Statement of Net Assets in accordance with this
         Section 4(b), the Initial Purchase Price will be adjusted, up or down,
         as follows:

                     (A)   if the amount of Net Assets shown on the Final
                           Closing Statement of Net Assets (the "Net Asset
                           Amount") is greater than THIRTY-SEVEN MILLION ONE
                           HUNDRED THREE THOUSAND DOLLARS ($37,103,000) (the
                           "Baseline Amount"), the Initial Purchase Price will
                           be increased by the amount by which the Net Asset
                           Amount is greater than the Baseline Amount, and such
                           amount by which the Initial Purchase Price is
                           increased will be paid by Buyer to Seller; and

                     (B)   if the Net Asset Amount is less than the Baseline
                           Amount, the Initial Purchase Price will be reduced by
                           the amount by which the Net Asset Amount is less than
                           the Baseline Amount, and such amount by which the
                           Purchase Price is reduced will be paid by Seller to
                           Buyer.

                  (iv) Any payment required under Section 4(b)(iii) shall bear
         interest from the Closing Date to the date of payment at a rate per
         annum equal to the prime interest rate from time to time in effect of
         Mellon Bank N.A. 

                  (v) Any adjustment to the Initial Purchase Price (together
         with interest thereon) required under Section 4(b)(iii) shall be made
         by wire transfer of immediately available U.S. Dollars within 


                                      -16-

         five (5) business days after the date that the Closing Statement of Net
         Assets is deemed to be the Final Closing Statement of Net Assets in
         accordance with this Section 4(b). The Initial Purchase Price, as so
         adjusted, shall hereinafter be referred to as the "Purchase Price."

and Buyer. Buyer shall furnish Seller with properly executed sales tax exemption

6.       REPRESENTATIONS AND WARRANTIES OF SELLER.

         Seller makes the following representations and warranties to Buyer (it
being expressly understood that any representation or warranty made with respect
to TSM shall also be deemed to include each TSM Predecessor-in-interest except
where inapplicable): 

         (a) Corporate Organization.

                  (i) Seller is a corporation duly organized, validly existing
         and in good standing under the laws of the State of Delaware. Seller
         has all requisite power and authority, corporate and otherwise, to
         carry on its business as it is currently conducted and to own or lease
         and operate the property and assets that it purports to own or lease
         and operate at the locations where such assets are now owned or leased
         and operated and to perform all of its obligations under the Material
         Contracts. Seller is duly licensed and qualified to do business and in
         good standing in all jurisdictions in which the character or location
         of the properties owned or leased by it or the nature of the business
         conducted by it makes such licensing or qualification necessary, except
         where the failure to be so licensed or qualified would not have a
         Material Adverse Effect. 

                  (ii) TSM is a limited liability company duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware. Each TSM Predecessor-in-interest was duly organized, and
         validly existing under the laws of the state of its incorporation on
         the date of its merger into its successor. 

                  (iii) TSM does not own, directly or indirectly, any shares of
         stock or other securities of any corporation or have any interest in
         any firm, partnership, association or other entity. 



                                      -19-
<PAGE>   24

                  (iv) TSM has all requisite power and authority, corporate and
         otherwise, to carry on its business as it is currently conducted and to
         own or lease and operate its assets where such assets are now owned or
         leased and operated and to perform all its obligations under the
         Material Contracts. 

                  (v) TSM is duly licensed and qualified to do business and is
         in good standing in all jurisdictions in which the character or
         location of the properties owned or leased by it or the nature of the
         business conducted by it makes such licensing or qualification
         necessary, except where the failure to be so licensed or qualified
         would not have a Material Adverse Effect; each such jurisdiction in
         which TSM is duly licensed or qualified to do business as a foreign
         corporation is listed on Schedule 6(a)(v). 

         (b) Due Authorization and Execution; Effect of Agreement. Seller has
all requisite power and authority, corporate and otherwise, to execute, deliver
and perform the obligations of Seller under this Agreement and the Related
Agreements and to consummate the transactions contemplated hereby. The
execution, delivery and performance by Seller of this Agreement and the
consummation by Seller of the transactions contemplated hereby have been duly
authorized and approved by all necessary and proper corporate action on the part
of Seller and no other proceedings on the part of the Board of Directors or the
shareholders of Seller are necessary to authorize this Agreement or to
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by Seller, constitutes the legal, valid and
binding obligation of Seller, and is enforceable against Seller in accordance
with its terms, except as such enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to or affecting
the enforcement of creditors' rights in general and by general principles of
equity.



                                      -20-
<PAGE>   25

         (c) No Conflict. Except as set forth on Schedule 6(c), none of the
execution, delivery or performance by Seller of this Agreement or of any
instruments or other documents to be delivered pursuant to this Agreement, or
the consummation by Seller of the transactions contemplated hereby or thereby
(i) will violate any provisions of any Law, order, judgment or decree or other
requirement applicable to Seller or any of its assets or constitute an event
which, with notice, lapse of time or both, would result in any such violation or
give any Governmental Authority or other Person the right to challenge any of
the transactions contemplated hereby or to exercise any remedy or obtain any
relief under any Law to which Seller or any of its assets may be subject; (ii)
will violate any provisions of the Certificate of Incorporation or By-laws of
Seller or any resolution adopted by the Board of Directors or the shareholders
of Seller or TSM; (iii) will require any Consent or notice under (except as set
forth on Schedule 6(c) or Schedule 6(d)), or conflict with, or result in the
breach or termination of, or constitute a default under (or constitute an event
which with notice, lapse of time or both would result in any such default
under), or permit the acceleration of the performance by Seller or TSM of any
Lease or Material Contract; or (iv) will result in or permit the creation of any
Lien upon any assets of Seller or TSM, except for Permitted Liens.

         (d) Consents. Except for Consents required under the HSR Act, no
material Consent of any governmental or regulatory authority or agency (a
"Governmental Authority") is required by or with respect to Seller in connection
with the execution and delivery of this Agreement by Seller, the execution,
delivery or performance by Seller of any instruments or other documents to be
delivered pursuant to this Agreement or the consummation by Seller of the
transactions contemplated hereby or thereby, other than any such requirement
that is applicable to Buyer as a result of the specific legal or regulatory
status of Buyer or as a result of any 



                                      -21-
<PAGE>   26

other facts that specifically relate to the business or activities in which
Buyer is or proposes to be engaged, other than the Business.

         (e) Capitalization of TSM; Ownership of Shares. The authorized capital
stock of TSM consists of 1,000 common shares, no par value, of which the only
shares outstanding are the 1,000 TSM Shares. Each of the TSM Shares has been
duly authorized and validly issued and is fully paid and nonassessable. Seller
is the record owner of all of the TSM Shares, free and clear of all Liens. There
are no authorized or outstanding warrants, convertible securities,
subscriptions, options, rights, calls, commitments, conversion rights, rights of
exchange, rights of first refusal, plans or other agreements of any nature
providing for or affecting the purchase, issuance, sale or transfer of any
issued or unissued capital stock or other securities of TSM, other than this
Agreement. None of the capital stock or other securities of TSM was issued in
violation of the Securities Act of 1933, as amended, or any other Law. The
delivery to Buyer of certificates representing all the TSM Shares (and a duly
executed instrument of transfer relating thereto) pursuant to this Agreement
will transfer to Buyer good, valid and marketable title thereto, free and clear
of all Liens.

         (f) Financial Statements. Attached hereto as Schedule 6(f) are (i) the
combined audited Statement of Net Assets as of September 30, 1997 (the
"September 30 Statement of Net Assets") and the Statement of Revenues and
Expenses (which, together with the September 30 Statement of Net Assets, are
hereinafter sometimes collectively referred to as the "September 30 Audited
Financial Statements") of the Business for the year then ended, together with
the report of D&T thereon and (ii) the combined unaudited Statement of Net
Assets as of March 31, 1998 (the "March 31 Unaudited Statement of Net Assets")
and the unaudited Statement of Revenues and Expenses (which, together with the
March 31 Unaudited Statement of Net Assets, are hereinafter sometimes
collectively referred to as the "March 31 Financial Statements") of the Business
for the period then ended. Each 



                                      -22-
<PAGE>   27

of the September 30 Financial Statements and the March 31 Financial Statements
(including any notes thereto) have been prepared from the books and accounts and
financial records of the Business and in accordance with the Accounting
Practices and Procedures of the Business applied on a consistent basis
throughout the periods covered thereby and, except as set forth in D&T's Report
on the September 30 Audited Financial Statements included in Schedule 6(f),
fairly present, in all material respects, the financial position of the Business
as of September 30, 1997 and March 31, 1998, respectively, and the results of
its operations for the periods then ended in conformity with generally accepted
accounting principles. The amounts reported in the September 30 Financial
Statements and the March 31 Financial Statements have been included in the
consolidated financial statements of Rockwell International Corporation for the
applicable period, which consolidated financial statements are presented in
accordance with generally accepted accounting principles. Neither the September
30 Audited Financial Statements nor the March 31 Financial Statements are
indicative of the financial position or results of operations of the Business
that would have existed if the Business had not operated as an integral part of
Rockwell and Seller, thus deriving associated benefits during the periods
presented. In addition, revenues, expenses, assets and liabilities presented in
the September 30 Audited Financial Statements and the March 31 Financial
Statements reflect intercompany services and certain, but not all, cost
allocations provided by Rockwell and Seller to the Business.

         (g) Inventory. As of the date hereof, the Inventory is in all material
respects of a quality useable and saleable in the Ordinary Course of Business
for the purpose for which it is intended, except to the extent reserved against
on the March 31 Unaudited Statement of Net Assets and for reserves incurred in
the Ordinary Course of Business after March 31, 1998.

         (h) Receivables. The receivables of the Business as of the date hereof
arose from bona fide sales and deliveries of goods, performance of 



                                      -23-
<PAGE>   28

services or other business transactions in the Ordinary Course of Business.
Except for reserves against such receivables on the March 31 Unaudited Statement
of Net Assets and for reserves incurred in the Ordinary Course of Business after
March 31, 1998 (which reserves are adequate to our knowledge and have been
calculated consistent with past practice), there is no material pending contest
or dispute with respect to the amount or validity of any amount of any such
receivables.

         (i) Title to Assets. Seller or TSM has good and marketable title to, or
a valid leasehold interest in, the properties and assets set forth on the March
31 Unaudited Statement of Net Assets or acquired after the date thereof, free
and clear of all Liens, except for (i) Permitted Liens and (ii) properties and
assets disposed of in the Ordinary Course of Business since March 31, 1998.

         (j) Contracts.

                  (i) Schedule 6(j) sets forth all of the following Contracts
         relating to the Business (each such item required to be set forth on
         Schedule 6(j) being referred to as a "Material Contract"):

                          the furnishing or receipt of services, the performance
                          of which will (i) extend over a period of one (1) year
                          or more or (ii) involve consideration in excess of
                          TWENTY-FIVE THOUSAND DOLLARS ($25,000);

                          Person (other than Buyer) for the purpose of
                          considering the purchase of the Business, or a portion
                          thereof, by such Person;

                     (E)  all Contracts for the employment of any individual on
                          a full-time, part-time, consulting or other basis
                          providing annual compensation in excess of FIFTY

                          benefits (other than pursuant to policies or plans of
                          general applicability);

                     (F)  all Contracts under which the Business has advanced or

                     (H)  all Contracts under which the Business has guaranteed
                          any indebtedness or obligation of any Person;

                     (I)  all Contracts with distributors, sales
                          representatives, manufacturers or other Persons
                          relating to the distribution, sale or manufacture of
                          products or services by the Business; and

         knowledge, the other party or parties thereto, including, without
         limitation, subcontractors, have complied in all material respects with
         the provisions of each Material Contract and are not in default
         thereunder (and there does not exist any condition which, after notice
         or lapse of time or both, would constitute a default thereunder by the
         Business or, to the best of Seller's knowledge, the other party or
         parties thereto). Each Material Contract is legal, valid, binding,
         enforceable and in full force and effect. No party to any Material
         Contract has repudiated any provision thereof. 

         (k) Leases.

                  (i) Schedule 6(k) contains a list of all leases, subleases and
         other arrangements relating to real property, whether as lessor or
         lessee, to which either Seller (with respect to the Business) or TSM is
         a party (a "Lease").

                  (ii) All Leases were entered into in the Ordinary Course of
         Business. The Business and, to the best of Seller's knowledge, the
         other party or parties thereto have complied in all material respects
         with the provisions of each Lease and are not in default thereunder
         (and there does not exist any condition which, after notice or lapse of
         time or both, would constitute a default thereunder by the Business or,
         to the best of Seller's knowledge, the other party or parties thereto).
         Each Lease is legal, valid, binding, enforceable and in full force and
         effect. No party to any Lease has repudiated any provision thereof. All
         facilities subject to Leases are supplied with utilities and other
         services necessary for the operation of such facilities as presently
         operated.

         (l) Employees.

         the employees of the Business (setting forth their names, titles or job
         descriptions, dates of hire, total annual compensation, 



                                      -26-

         including bonuses, location and employment classification) who are as
         of the date hereof (x) actively employed by the Business or (y) on an
         approved leave of absence, workers' compensation, short or long-term
         disability, military leave, lay-off or other approved leave of absence.
         The employees set forth on Schedule 6(l)(i) are hereinafter
         collectively referred to as the "Employees."

                  (ii) There are no collective bargaining or other labor union
         contracts or other agreements covering wages, hours and terms of
         employment applicable to the Employees. Each of Seller (with respect to
         the Business) and TSM has complied in all material respects with all
         applicable Laws relating to employment, including equal employment
         opportunity, affirmative action, wages and hours, safety and health,
         and labor-management relations. Each Employee is authorized for
         employment by the Business in accordance with the Immigration and
         Naturalization Act, as amended, and regulations promulgated under that
         statute.

                  (iii) No unfair labor practice, complaint, grievance, charge
         of discrimination or claim against either of Seller (with respect to
         the Business) or TSM is pending or, to the best of Seller's knowledge,
         threatened before the Equal Employment Opportunity Commission, the
         National Labor Relations Board or any other labor relations board or
         similar Governmental Authority. There are no pending collective
         bargaining negotiations relating to any Employees, or agreements with,
         or pending petitions for recognition of, a labor union or association
         as the exclusive bargaining agent or other representative for any or
         all of such Employees, nor has there been, within the two (2) year
         period immediately preceding the date hereof, any such petition pending
         or any general solicitation of representation cards by any union
         seeking to represent any or all of the Employees as their exclusive
         bargaining agent or other representative at any time. There is no labor
         strike, lockout, 



                                      -27-

         dispute, disturbance, slowdown, or work stoppage pending or, to the
         best of Seller's knowledge, threatened against or involving the
         Business, nor has any strike, lockout, or work stoppage been enjoined
         by any writ, order, injunction or decree of any court or any other
         Governmental Authority.

        (m) Litigation.

         order, ruling, writ, decree, judgment or stipulation by or with any
         arbitrator, court or other Governmental Authority to which Seller (with
         respect to the Business) or TSM is a party or by which Seller (with
         respect to the Business) or TSM is bound, and which, in the case of
         Seller, relates to or affects the Business, TSM, this Agreement or the
         transactions contemplated hereby, is in effect and (y) neither Seller
         (with respect to the Business) nor TSM is a party to or engaged in or,
         to the best of Seller's knowledge, threatened with any action, suit,
         investigation or other proceeding at law or in equity or any
         arbitration or governmental, administrative, regulatory or other
         proceeding by or before any arbitrator, court or other Governmental
         Authority which relates to or affects the Business, TSM, this Agreement
         or the transactions contemplated hereby, and, to the best of Seller's
         knowledge, no event has occurred and no condition exists which could
         reasonably be expected to result in any such action, suit,
         investigation, arbitration or proceeding.

                  (ii) Neither Seller (with respect to the Business) nor TSM is
         in default under or with respect to any order, ruling, writ, decree,
         judgment or stipulation of the type described in Section 6(m)(i) above.

                  (iii) There have been no recalls or notifications with respect
         to products or services of the Business made by any Governmental



                                      -28-

         Authority or voluntarily by Seller (with respect to the Business) or
         TSM.

         (n) Taxes. Each of Seller and TSM has (x) timely filed all material Tax
Returns that are or were required to be filed by each of them on or before the
date hereof and (y) paid or caused to be paid all Taxes shown to be due and
payable on such Tax Returns which are not being contested in good faith. None of
the assets of Seller (with the respect to the Business) or TSM is (a) held in an
arrangement for which Tax Returns as a partnership are being filed, (b) subject
to a safe harbor lease (pursuant to Section 168(f)(8) of the Internal Revenue
Code of 1954 as in effect after the Economic Recovery Tax Act of 1981 and before
the Tax Reform Act of 1986), (c) tax-exempt use property (within the meaning of
Section 168(h) of the Code) or (d) tax-exempt bond financed property (within the
meaning of Section 168(g)(5) of the Code). No consent under Section 341(f) of
the Code has been filed with respect to any asset or property held by Seller
(with respect to the Business) or TSM.

         (o) Permits. All material Permits required by any Law for the operation

are identified on Schedule 6(o) hereto. Either Seller (with respect to the
Business) or TSM (as the case may be) is in compliance with all such Permits.

         (p) Sufficiency of Purchased Assets. Except as set forth on Schedule
6(p), the Assets and the assets of TSM purchased by virtue of the purchase of
the TSM shares constitute (i) all of the material assets and/or rights which are
used in the operation of the Business as it is being conducted as of the date
hereof and (ii) all the property (real and personal, tangible and intangible,
including, without limitation, Intellectual Property) necessary for the conduct
by Buyer of the Business as it is being conducted as of the date hereof. None of
the Assets is in need of maintenance or repairs except for ordinary and routine
maintenance.

         (q) Intellectual Property. Schedule 2(b)(xii) identifies each patent or
registration that has been issued to the Seller or TSM with respect to any
Intellectual Property used in the Business and conveyed to Buyer hereunder and
each pending patent application or application for registration that Seller or
TSM has made with respect to any Intellectual Property used in the Business and
conveyed to Buyer hereunder. Schedule 2(b)(xi) identifies each trade name,
trademark or service mark used by the Seller or TSM in connection with the
Business and conveyed to Buyer hereunder. Either Seller or TSM or both owns, or
is licensed or otherwise has the legal right to use, all the Intellectual
Property used in and necessary for the operation of the Business, and the
consummation of the transactions contemplated hereby will not alter or impair
any such rights. Except as set forth on Schedule 6(q), (i) to the best of
Seller's knowledge, any Intellectual Property used in any service rendered by,
in any product, process, method, part or material produced or used by the
Business, does not infringe upon any rights owned or held by any other Person,
(ii) there is not pending nor, to the best of Seller's knowledge, threatened,
any claim or litigation against the Business contesting the rights of the
Business to such Intellectual Property or the validity of such Intellectual
Property or the Business's use of any Intellectual Property, (iii) no
Intellectual Property of the Business is subject to any outstanding order,
ruling, decree, judgment or stipulation by any arbitrator, court or other
Governmental Authority, nor is there any pending proceeding relating thereto,

misappropriation of the Intellectual Property of the Business by any other
Person. Either Seller or TSM holds all licenses, if any, from third parties that
are necessary to the conduct of the Business as conducted as of the date hereof.
Except as set forth on Schedule 6(q), no other Person has any rights or licenses
under any of the Intellectual Property of the Business.

         (r) Employee Benefits. Schedule 6(r) sets forth a list of each Employee
Plan. All Employee Plans that are Employee Benefit Plans have been operated and
maintained in compliance in all respects with the provisions of ERISA, the Code
and the rules and regulations promulgated thereunder. Seller and its Affiliates
(including TSM) have performed all obligations, whether arising by operation of
Law or by contract, required to be performed by them in connection with each
Employee Plan. The Employee Plans have been administered in compliance with
their respective governing documents and applicable Law. Each of the Employee
Plans that are employee pension benefit plans (collectively the "Pension Plans")
satisfies the requirements of Section 401(a) of the Code and each of the Pension
Plans has received a favorable determination letter from the Internal Revenue
Service regarding such qualified status and has not, since receipt of the most
recent favorable determination letter, been amended or operated in any way which
would adversely affect such qualified status. There is no matter pending (other
than routine qualification determination filings) with respect to any Employee
Plan before the Internal Revenue Service, the Department of Labor or the Pension
Benefit Guaranty Corporation (the "PBGC"). There are no actions, suits or claims
pending (other than routine claims for benefits) or, to the best of Seller's
knowledge, threatened against, or with respect to, any Employee Plan or its
assets. All contributions required to be made to the Pension Plans pursuant to
their terms and provisions and applicable Law have been made timely. As to each
Pension Plan: there has been no event or condition which presents the material
risk of any termination; no accumulated funding deficiency, whether or not
waived, within the meaning of Section 302 of ERISA or Section 412 of the Code
has been incurred; no notice of intent to terminate such Pension Plan has been
given under Section 4041 of ERISA; no proceeding has been instituted under
Section 4042 of ERISA to terminate such Pension Plans; there has been no
termination or partial termination of such Pension Plan within the meaning



                                      -31-
<PAGE>   36

of Section 411(d)(3) of the Code; and no Liability to the PBGC has been incurred
(other than Liability for premium payments in the normal course). None of the
Employee Plans that are Employee Benefit Plans has engaged in a "prohibited
transaction" (as defined in Section 406 of ERISA and Section 4975 of the Code)
with a "disqualified person" or a "party in interest" (as such terms are defined
in Section 4975(e)(2) of the Code and Section 3(14) of ERISA) for which an
exemption has not been received from the Department of Labor and/or the Internal
Revenue Service. No "reportable event" (as defined in Section 4043 of ERISA) has
occurred with respect to any Employee Plan that is an Employee Benefit Plan
subject to Title IV of ERISA other than those events as to which the 30 days'
notice requirement is waived under PBGC Regulation Section 2615. No event or
transaction has occurred with respect to any Employee Plan that would result in
the imposition of a tax under any Sections 4971, 4972, 4876, 4977, 4979 or 4980B
of the Code. With respect to each Pension Plan, the present value of all accrued
benefits, determined on a plan termination basis using the actuarial assumptions
established by the PBGC as in effect on the date of determination, does not
exceed the fair market value of the assets (which for this purpose shall not
include any accrued but unpaid contributions) of such Pension Plan. Except as
set forth on Schedule 6(r), Seller and its Affiliates (including TSM) do not
maintain or contribute to any plan which provides, or has any liability to
provide, life insurance, medical or other employee welfare benefits to any
Employee upon their retirement or termination of employment, except as may be
required by Law, and Seller and its Affiliates (including TSM) have not
represented, promised or contracted (whether in oral or written form) to any
Employee (either individually or to Employees as a group) that such Employee(s)
would be provided with life insurance, medical or other employee welfare
benefits upon their retirement or termination of employment. Neither Seller
(with regard to the Business) nor TSM and its Affiliates nor any ERISA Affiliate
has participated in, has been obliged to contribute to or has incurred any



                                      -32-

unpaid withdrawal liability under, any Multiemployer Plan within the six (6)
year period immediately preceding the date hereof.

         related thereto, currently or formerly owned, leased, used or operated
         by Seller (with respect to the Business) or TSM or any predecessor
         thereof ("Premises") in a manner which violates any Environmental
         Requirement, or for which cleanup or corrective action of any kind is
         or could be required or authorized under any Environmental Requirement;

                  (ii) the Premises and the uses and activities thereon,
         including, but not limited to, the use, maintenance and operation at

         Business) or TSM, comply in all material respects with all
         Environmental Requirements;

                  (iii) no notice of violation, Lien, complaint, suit, judgment,
         injunction, writ, decree, order or other notice with respect to the
         environmental condition of the Premises or regarding the disposal or
         release of Hazardous Materials from the Premises onto any other
         property or into the environment is outstanding, or, to the knowledge
         of Seller, threatened, nor has any such notice been issued which has
         not been fully satisfied and complied with in a timely manner so as to
         bring the Premises into full compliance with every Environmental
         Requirement, and no other such notice has been received;

                  (iv) the Premises are not on the "National Priorities List" or
         the CERCLIS list of the USEPA, or any similar state or local list and
         are not the subject of any federal, state or local investigation



                                      -33-
<PAGE>   38

         evaluating whether any remedial action is needed to respond to a
         release of any Hazardous Materials into the environment;

                  (v) no Lien in favor of any Governmental Authority for (x) any
         Liability under any Law or (y) Environmental Damages arising from costs
         incurred by such Governmental Authority in response to a release of a
         Hazardous Material into the environment has been filed or attached to
         any Premises; and

                  (vi) neither Seller (with respect to the Business) nor TSM has
         received notice that any Person (including past or present employees)
         may have had his or her health impaired as a result of exposure to any
         Hazardous Materials located on, at, in, under or about the Premises.

         (t) Absence of Certain Changes or Events.

                  (i) Except as set forth on Schedule 6(t)(i), since March 31,
         1998, there have not been any changes in the Assets or Liabilities of
         the Business which, individually or in the aggregate, have had or could
         reasonably be expected to have a Material Adverse Effect. Except as set
         forth on Schedule 6(t)(i), from and after March 31, 1998 to the date
         hereof, the Business has been conducted only in the Ordinary Course of
         Business and neither Seller (with respect to the Business) nor TSM has:

                          ($25,000);

                     (C)  except in accordance with the Ordinary Course of
                          Business, (i) made any change in the rate of
                          compensation, commission, bonus or other direct or

                          officers, Employees or agents, or agreed or promised
                          (orally or otherwise) to pay, conditionally or

                  (iii) All vehicles constituting Assets as of the Closing Date
         may continue to be used without re-marking (except as to legally

         any of its Affiliates, the Parties will cooperate in constituting Buyer
         as a registered user (or its equivalent) in each of the countries in

         reasonable satisfaction of Seller. Any expenses for registering such
         mark or constituting Buyer as a registered user in any country shall be
         borne by Buyer. Any registration of Buyer as a registered user of any

         all necessary steps to cause such registration to be so expunged upon
         such termination or breach or threatened breach.

         (d) Performance of Contracts. Buyer will assume as of the Closing Date

                  (i) Preparation and Filing of Tax Returns. Seller shall
         prepare and timely file or shall cause to be prepared and timely filed
         all appropriate Tax Returns in respect of TSM or any TSM
         Predecessor-in-interest, its business, assets or operations that (x)
         are required to be filed on or before the Closing Date or (y) are
         required to be filed after the Closing Date and (A) are consolidated
         Tax Returns or (B) that are required to be filed by TSM or any TSM
         Predecessor-in-interest on a separate return basis for any tax period
         ending on or before the Closing Date. Buyer shall prepare and timely
         file or shall cause to be prepared and timely filed all Tax Returns
         required of TSM, for or in respect of its business, assets or
         operations for any period ending after the Closing Date. Any such Tax
         Returns that include tax periods ending on or before the Closing Date
         or that include the business, assets or operations of TSM or any TSM
         Predecessor-in-interest through the Closing Date shall, insofar as they
         relate to TSM or any TSM Predecessor-in-interest, be on a basis
         consistent with the last previous such Tax 



                                      -48-
<PAGE>   53

         Returns filed in respect of TSM or any TSM Predecessor-in-interest,
         unless Seller or Buyer, as the case may be, concludes that there is no
         reasonable basis for such position. TSM (prior to the Closing) shall
         not modify any position taken on any Tax Return of TSM or any TSM
         Predecessor-in-interest which relates to TSM's business, assets or
         operations filed on or prior to the Closing Date without the prior
         written consent of Buyer, which consent shall not be unreasonably
         withheld or delayed.

                  (ii) Payment of Taxes by Seller. Seller shall timely pay or
         cause to be paid all Taxes due with respect to tax periods ending on or
         before the Closing Date or with respect to Tax Returns of TSM or any
         TSM Predecessor-in-interest that Seller is required to prepare and
         timely file pursuant to Section 10(a)(i) hereof. With respect to any
         Tax Returns of TSM other than those described in the preceding
         sentence, which are required to be filed for a period ending after the
         Closing Date and which include on a separate, consolidated or combined
         basis the business, assets or operations of TSM or any TSM Predecessor-
         in-interest through the Pre-Closing Period, Buyer shall compute or
         cause to be computed the amount of Taxes that would be reflected on a
         separate return of TSM or any TSM Predecessor-in-interest for the
         Pre-Closing Period (assuming that such return was permitted or required
         in respect thereof and in the case of such Taxes that are Income Taxes,
         such Income Taxes shall be computed by determining the item of income,
         expense, deduction, loss or credit on a "closing of the books" basis as
         of the Closing Date) and shall follow comparable procedures in
         determining any Taxes of TSM or any TSM Predecessor-in-interest for
         which no Tax Return is required, and Seller shall pay to Buyer (after a
         properly supported 



                                      -49-
<PAGE>   54

         written request by Buyer) on the due date, including extensions, if
         any, of such Tax Return (or, if no Tax Return is required, the due date
         of the payment of Taxes), the aggregate amount, if any, of such Taxes.

                  (iii) Tax Refunds or Credits. In the event that either Buyer
         or TSM receives a refund or credit of Taxes with respect to any tax
         period ending on or before the Closing Date or with respect to the
         Pre-Closing Period for which TSM or Seller has made a payment, then the
         amount of such refund or credit shall be treated as an offset for the
         account of Seller against Taxes, if any, for which Seller is liable
         pursuant to this Agreement that are attributable to adjustments
         correlative to the adjustments giving rise to the refund or credit; if
         no such Taxes are available for offset, such amounts shall be refunded
         to Seller.

                  (iv) Federal Tax Treatment of Transfer of TSM. At the Closing,
         Seller shall transfer the business of TSM to Buyer in such a manner as
         to constitute a sale of assets to Buyer for U.S. federal Income Tax
         purposes, and Seller and Buyer agree to treat such transfer of Seller's
         interest in TSM as a sale by Seller to Buyer of the assets held by TSM
         for U.S. federal Income Tax purposes.

                  (v) Allocation of Consideration. The Purchase Price and the
         liabilities of the Business and TSM shall be allocated among the assets
         of TSM, the Assets and the covenant not to compete in Section 15 in
         accordance with a schedule (the "Consideration Allocation") to be
         delivered by Buyer to Seller within ninety (90) days after the Closing
         Date. The Consideration Allocation shall be prepared in accordance with
         Treas. Regs. Sections 1.338(b)-2T(b) and 1.1060-1T(d) (or any other
         comparable provisions of state or local Tax law) or any 



                                      -50-
<PAGE>   55

         successor provision. Seller will have the right to raise reasonable
         objections to the Allocation Schedule within thirty (30) days after its
         receipt thereof, in which event Seller and Buyer will negotiate in good
         faith to resolve such objections. If the parties have not resolved such
         objections within 30 days after the initiation of such attempts, such
         objections will be resolved by an arbitration to be conducted by a
         nationally recognized independent accounting firm acceptable to Buyer
         and Seller, whose fees and expenses will be borne equally by Buyer and
         Seller. Buyer and Seller will be bound by the determination of the
         arbitrator rendered in such arbitration. Each of Seller and Buyer agree
         that they will report and cause to be reported all federal, state,
         provincial, local and other Tax consequences of the transactions
         contemplated hereby in a manner consistent with the Consideration
         Allocation, and shall not make any inconsistent statement or adjustment
         on any returns or during the course of any Internal Revenue Service or
         other Tax audit.

                  (vi) Cooperation on Tax Matters. Buyer and Seller shall (x)
         furnish or cause to be furnished to each other, upon request, as
         promptly as practicable, such information (including access to books
         and records) and assistance relating to the Business and TSM as is
         reasonably necessary for the preparation and filing of any return,
         report, statement or form (including the Tax workpaper preparation
         packages necessary for the preparation of Tax Returns which the Seller
         is obligated to prepare or cause to be prepared), for the preparation
         for any audit and for the prosecution or defense of any claim, suit or
         proceeding relating to any proposed adjustments of Taxes and (y) use
         their reasonable best efforts, upon request, to obtain any certificate
         or other document from any taxing authority, 



                                      -51-

         customer of the Business or any other Person as may be necessary to
         mitigate, reduce or eliminate any Taxes that would otherwise be imposed
         with respect to the Business or TSM, provided that neither Buyer nor
         Seller shall be required to take any action under this Section
         10(a)(vi) that is inconsistent with another tax position being taken by
         such Party.

                  (vii) Tax Contests.

                     (A)  Notice. If a claim shall be made by any taxing
                          authority which, if successful, would result in an
                          indemnity payment by Seller pursuant to Section 10(c)
                          hereof (a "Tax Claim"), or if an audit is commenced by
                          any taxing authority with respect to Taxes that could
                          give rise to a Tax Claim (a "Tax Audit"), Buyer shall,
                          promptly following Buyer's receipt of the same, notify
                          Seller in writing of such Tax Claim or such Tax Audit,
                          as the case may be. If such notice is not given to
                          Seller to apprise Seller of the nature of the Taxes
                          (in each instance taking into account the facts and
                          circumstances), Seller shall not be liable to Buyer to
                          the extent that Seller's position is actually
                          prejudiced as a result thereof. Seller shall promptly
                          notify Buyer if a Tax Claim is made or a Tax Audit is
                          commenced by any taxing authority which could result
                          in Buyer (or an Affiliate of Buyer) or TSM paying
                          Taxes for a taxable period ending after the Closing
                          Date. If such notice is not given to Buyer to apprise
                          Buyer of the nature of the Taxes (in each instance
                          taking into account the facts and circumstances),
                          Buyer shall not 



                                      -52-
<PAGE>   57

                          be liable to Seller to the extent that Buyer's
                          position is actually prejudiced as a result thereof.

                     (B)  Control of Proceedings. Seller shall have the right,
                          at its option, at its own expense and with its own
                          counsel, upon timely notice to Buyer, to assume and
                          control the conduct of any Tax Audit and the defense
                          of any suit, action or proceeding with respect to any
                          Tax Claim provided that Seller and Buyer shall jointly
                          control all proceedings taken in connection with any
                          Tax Audit or Tax Claim relating to Taxes for any
                          period that includes but does not end on the Closing
                          Date, that could result in Buyer (or a Buyer
                          Affiliate) or TSM paying Taxes for which Seller is not
                          liable, and provided further that Buyer shall control
                          all proceedings relating to any tax period beginning
                          subsequent to the Closing Date. If Seller elects to
                          assume the defense of any Tax Audit or Tax Claim as
                          provided herein, notwithstanding anything to the
                          contrary contained herein, (i) Seller shall procure
                          Buyer's written consent to any settlement with respect
                          to the Taxes if the effect of such settlement would be
                          an increase in the liability of Buyer, TSM or of any
                          other Affiliate of Buyer for any Taxes for any period
                          ending after the Closing Date and if Seller would not
                          be obligated under this Section 10(a) to pay the full
                          amount of such increase in Taxes, and (ii) Seller
                          shall keep Buyer informed of all material developments
                          and events relating to such Tax Audit or Tax Claim.
                          Except 



                                      -53-
<PAGE>   58

                          as provided above, Seller at its sole option may
                          pursue or forego any and all administrative appeals,
                          proceedings, hearings and conferences with the taxing
                          authority with respect to any Tax Claim over which
                          Seller has exclusive control and may, at its sole
                          option, either pay the Taxes claimed and sue for a
                          refund where applicable Law permits such refund suits
                          or may contest the Tax Claim in any permissible
                          manner and prosecute such contest to a determination
                          in a court of initial jurisdiction and to a
                          determination in an appellate court.

                     (C)  Tax Indemnification. Seller shall indemnify Buyer
                          against and hold harmless from (i) all Taxes for which
                          Seller is liable, including Taxes for which they are
                          liable under this Agreement and (ii) all Taxes
                          attributable to a breach by Seller of any of its
                          representations, warranties or covenants relating to
                          Taxes under this Agreement. Notwithstanding the
                          foregoing, Seller shall not indemnify Buyer or TSM
                          from any liability for Taxes attributable to any
                          action taken by Buyer or TSM after Closing (other than
                          any action expressly required or otherwise expressly
                          contemplated by this Agreement) (a "Buyer's Tax Act").
                          Buyer shall indemnify Seller against and hold harmless
                          from Taxes caused by a Buyer's Tax Act and all Taxes
                          for which Buyer is liable under this Agreement.

                     (D)  Time Limitation. The right of Buyer to indemnification
                          for losses arising under this Section 10(a) shall
                          apply 



                                      -54-
<PAGE>   59

                          only to those claims for indemnification, notice of
                          which is given pursuant to this Agreement to Seller
                          on or before 60 days following the expiration of the
                          statute of limitations (giving effect to any waiver,
                          mitigation or extension thereof) applicable to any
                          Taxes in question.

                     (E)  Exclusivity. All rights and obligations of the Parties
                          hereto with respect to Taxes, including all rights of
                          Buyer to indemnification by Seller, shall be governed
                          exclusively by the provisions of this Section 10(a),
                          and in particular the provisions of Section 14(a)
                          shall not apply to Damages arising under this Section
                          10(a).

                  (viii) No Election to Treat as a Corporation. Seller will not
         make, or cause to be made, any election to treat TSM as an association
         taxable as a corporation either (1) for federal Tax purposes, pursuant
         to Treasury Regulations Section 301.7701-3 (or any successor provision)
         or (2) pursuant to any similar provision of state or local Law.

         (b) Governmental Consents. 

                  (i) Consents of Governmental Authorities. Each of the Parties
         will use its reasonable best efforts to obtain any Consents of
         Governmental Authorities in connection with the consummation of the
         transactions contemplated by this Agreement (including efforts to
         influence any Governmental Authority to decline to challenge or
         otherwise object to the transaction). Without limiting the generality
         of the foregoing, each of the Parties will file any Notification and
         Report Forms and related material that it may be required to file with
         the Federal Trade Commission and the Antitrust 



                                      -55-
<PAGE>   60

         Division of the United States Department of Justice under the HSR Act,
         will use its reasonable best efforts to obtain an early termination of
         the applicable waiting period thereunder, and will make any further
         filings pursuant thereto that may be necessary, proper, or advisable in
         connection therewith. Each of the Parties will promptly furnish to the
         other such necessary information and reasonable assistance as the other
         may request in connection with its preparation of any filing or
         submission which is necessary under the HSR Act. Each of the Parties
         will promptly provide the other with copies of all written
         communications (and memoranda setting forth the substance of all oral
         communications) between each of them or their representatives, on the
         one hand, and any Governmental Authority, on the other hand, with
         respect to this Agreement or the transactions contemplated hereby.
         Without limiting the generality of the foregoing, each of the Parties
         will promptly notify the other of the receipt and content of any
         inquiries or requests for additional information made by any
         Governmental Authority in connection therewith and shall (i) comply
         promptly with any such inquiry or request in a manner considered
         appropriate by that Party consistent with the above, and (ii) promptly
         provide the other with a description of the information provided to any
         Governmental Authority with respect to any such inquiry or request. In
         addition, each of the Parties will keep the other apprised of the
         status of any such inquiry or request. 

                  (ii) Post-Closing Divestiture. Buyer shall take any and all
         actions, enter into any agreement, accept any judgment, decree or order
         and give any undertaking that may be required to eliminate any
         impediment to Closing, including actual or threatened litigation,



                                      -56-
<PAGE>   61

         arising under the antitrust laws of the United States or any state
         thereof (an "Impediment") that can be eliminated by the agreement by
         Buyer to a commercially reasonable divestiture of a portion of the
         Business (a "Divestiture") and Buyer shall agree to implement such
         Divestiture if necessary to eliminate the Impediment. If the Parties or
         Buyer determines that it is reasonably apparent that a Divestiture is
         available as a remedy and that it is reasonably likely that a
         Divestiture will be required in order to remove an Impediment, then not
         later than ten (10) days following such determination, the Closing
         shall occur (provided that no relevant Governmental Authority objects
         thereto) and the Parties shall cause the Initial Purchase Price to be
         released from escrow and paid to Seller in accordance with the terms of
         the Escrow Agreement.

                  (iii) Pre-Closing Corrective Actions. If and only if the
         Parties determine that the Impediment cannot reasonably be removed by a
         post-Closing Divestiture as set forth in Section 10(b)(ii) above:

                     (A)  If the Parties determine that it is reasonably
                          apparent that Buyer's acquisition of certain of
                          Seller's or TSM's assets will likely present an
                          Impediment to a prompt Closing, then Buyer agrees to
                          proceed promptly to a Closing with respect to the
                          remaining assets and to cause the Initial Purchase
                          Price to be released from the escrow and paid to
                          Seller in accordance with the terms of the Escrow
                          Agreement, in which event Seller shall, if reasonably
                          feasible and if agreeable to any relevant Governmental
                          Authorities, engage Morgan Stanley or Piper Jaffray or
                          another mutually agreeable

                          investment banking firm to sell the assets not
                          acquired by Buyer and remit to Buyer the proceeds
                          received from such sale, less the expenses incurred
                          by Seller in connection therewith, provided in this
                          event that the assets not acquired by Buyer shall
                          constitute the equivalent of a Divestiture.

                     (B)  If the Impediment cannot be removed by a pre-Closing
                          restructuring as described in Section 10(b)(iii)(A)
                          above, but can only be removed by a Divestiture by
                          Seller prior to Closing, Seller shall engage Morgan
                          Stanley or Piper Jaffray or another mutually agreeable
                          investment banking firm to make such Divestiture. Not
                          later than ten (10) days following consummation of
                          such Divestiture, the Closing shall occur, the Parties
                          shall cause the Initial Purchase Price to be released
                          from the escrow and paid to Seller in accordance with
                          the terms of the Escrow Agreement, and at the Closing
                          Seller shall remit to Buyer the proceeds Seller
                          received from the Divestiture, less the expenses
                          incurred by Seller in connection therewith.

                  (iv) Termination. Buyer shall not be required to consummate
         the transactions contemplated hereby, and may terminate this Agreement,
         if the Parties determine that a consummation would require a remedy
         other than, and, in Buyer's and Seller's good faith judgment, more
         onerous to Buyer than, a Divestiture.

         (c) Insurance. Coverage of the Business under all insurance policies of
Seller and its Affiliates shall cease as of the Closing Date. From and after the
Closing Date, Buyer will be responsible for obtaining 



                                      -58-

and maintaining all insurance coverages with respect to the Business. Buyer will
have no rights with respect to any insurance policies of Seller or any of its
Affiliates, except that Buyer will have the right to assert claims (and Seller
will use reasonable best efforts to assist the Buyer in asserting claims) for
any loss, Liability or damage with respect to Assets under such insurance
policies which are third-party "occurrence basis" policies ("Occurrence Basis
Policies") arising out of insured incidents occurring from the date coverage
thereunder first commenced until the Closing Date to the extent that the terms
and conditions of any such Occurrence Basis Policies and agreements relating
thereto so allow, provided that, (i) all of Seller's and its Affiliates'
reasonable costs and expenses incurred in connection with the foregoing are
promptly paid by Buyer, (ii) Seller and its Affiliates may, at any time, without
Liability or obligation to Buyer or any of its Affiliates, amend, commute,
terminate, buy-out, extinguish Liability under or otherwise modify any
Occurrence Basis Policies (and such claims shall be subject to any such
amendments, commutations, terminations, buy-outs, extinguishments and
modifications), (iii) such claims will be subject to (and recovery thereon will
be reduced by the amount of) any applicable deductibles, retentions,
self-insurance provisions or any payment or reimbursement obligations of Seller
or any Affiliate of Seller in respect thereof and (iv) such claims will be
subject to exhaustion of aggregate limits. None of Seller or its Affiliates will
bear any Liability for the failure of an insurance carrier to pay any claim
under any Occurrence Basis Policy.

         (d) Post-Closing Access; Preservation of Records.

                  (i) From and after the Closing, Buyer shall make or cause to
         be made available to Seller and its agents and employees all books,
         records and documents of Buyer and its Affiliates relating to the



                                      -59-
<PAGE>   64

         Business (and the assistance of Buyer's and its Affiliates' employees
         responsible for such books, records and documents) during regular
         business hours as may be reasonably necessary for (w) preparing Tax
         Returns and financial statements and responding to Tax Audits covering
         operations and transactions at or prior to the Closing Date, (x)
         investigating, settling, preparing for the defense or prosecution of,
         defending or prosecuting any legal action, suit, investigation or other
         proceeding pending, threatened or anticipated by or against Seller or
         any of its Affiliates or any of their properties, officers, directors
         or employees (or for which Seller or any of its Affiliates has any
         obligations) before any court, arbitrator or Governmental Authority,
         (y) preparing reports to stockholders and Governmental Authorities or
         (z) such other purposes for which access to such documents is believed
         by Seller to be reasonably necessary; provided, however, that access to
         such books, records, documents and employees shall not unreasonably
         interfere with the normal operations of Buyer and its Affiliates and
         the reasonable out-of-pocket expenses of Buyer incurred in connection
         therewith shall be paid by Seller. Buyer shall maintain and preserve
         all such books, records and other documents for the greater of (a) six
         years after the Closing Date or (b) any applicable statutory or
         regulatory retention period, as the same may be extended.

                  (ii) From and after the Closing, Seller shall make or cause to
         be made available to Buyer and its agents and employees all books,
         records and documents of Seller and its Affiliates relating to the
         Business during regular business hours for the same purposes, to the
         extent applicable and with the same requirements regarding



                                      -60-
<PAGE>   65

         maintenance and preservation imposed on Buyer as set forth in Section
         10(d)(i) above; provided, however, that access to such books, records
         and documents shall not unreasonably interfere with the normal
         operations of Seller and the reasonable out-of-pocket expenses of
         Seller incurred in connection therewith shall be paid by Buyer.

                  (iii) The parties acknowledge that all such information
         provided to the other party under this Section 10(d) is subject to the
         terms of the Confidentiality Agreement between the Parties dated April
         9, 1998 (the "Confidentiality Agreement").

         (e) Risk of Loss. 

                  (i) The risk of any loss, damage, impairment, confiscation, or
         condemnation of any of the Assets (which for the purpose of this
         Section 10(e) shall be deemed to include the assets of TSM) from any
         cause whatsoever shall be borne by Seller (or TSM in the case of assets
         of TSM) at all times prior to the Closing. In the event of any loss,
         damage, impairment, confiscation, or condemnation in excess of FIFTY
         THOUSAND DOLLARS ($50,000), whether or not covered by insurance, Seller
         shall promptly notify Buyer of such loss, damage, impairment,
         confiscation, or condemnation in excess of FIFTY THOUSAND DOLLARS
         ($50,000). Such notice shall state the estimated cost of repair,
         replacement or restoration of such Assets and whether Seller intends to
         repair, replace or restore (or cause the repair, replacement or
         restoration of) the Assets to substantially the same condition as prior
         to such event.

                  (ii) If Seller, at its expense, repairs, replaces, or restores
         (or causes to be repaired, replaced or restored) such Assets to
         substantially the same as their prior condition to the reasonable



                                      -61-
<PAGE>   66

         satisfaction of Buyer before the Closing, Seller (or its Affiliates
         other than TSM) shall be entitled to all insurance proceeds and
         condemnation awards, if any, by reason of such award or loss.

                  (iii) If Seller does not or cannot repair, restore or replace
         (or cause to be repaired, restored or replaced) lost, damaged,
         impaired, confiscated or condemned Assets having a replacement cost in
         excess of FIFTY THOUSAND DOLLARS ($50,000) in the aggregate or informs
         Buyer that it does not intend to repair, restore or replace (or cause
         to be repaired, restored or replaced) such Assets, Buyer may at its
         option: (x) terminate this Agreement pursuant to Section 13(a)(ii); or
         (y) proceed to the Closing without Seller completing (or causing) the
         restoration and replacement of such Assets; provided that Seller (or
         its Affiliates) shall retain all rights under applicable insurance
         policies and condemnation awards, if any, and Seller shall use its
         reasonable best efforts to the extent permitted by the terms of such
         insurance policies or condemnation awards or by applicable Law, to
         assign (or cause the assignment of) to Buyer such rights and awards,
         provided that all of Seller's (or any of its Affiliates') out-of-pocket
         costs and expenses incurred in connection with the foregoing are
         promptly reimbursed by Buyer and, provided further, that such claims
         shall be subject to (and recovery thereon shall be reduced by the
         amount of) any applicable deductibles, retentions, self-insurance
         provisions or any payment or reimbursement obligation of Seller or any
         of its Affiliates in respect thereof; and in such event, Seller shall
         have no further Liability with respect to the condition of the Assets
         directly attributable to the loss, damage, impairment, confiscation, or
         condemnation.

                  (iv) If Seller informs Buyer that it does not intend to
         repair, restore or replace (or cause the repairing, restoration or
         replacement of) the lost, damaged, impaired, confiscated or condemned
         Assets, then Buyer will notify Seller of a decision under the options
         described in Sections 10(e)(iii)(x) and (y) above within ten (10)
         business days after Seller's notice to Buyer of the damage or
         destruction of Assets, the estimate of the costs to repair or replace
         and Seller's intention not to repair, restore or replace (or cause such
         repairing, restoration or replacement). If Seller states that it
         intends to restore (or cause the restoration of) the damaged Assets and
         if Seller has not restored (or caused such restoration of) such damaged
         Assets immediately prior to the Closing Date, then, notwithstanding any
         prior delivery of a notice by Buyer to proceed pursuant to this Section
         10(e)(iv), Buyer shall have the right either to postpone the Closing or
         terminate this Agreement pursuant to Section 13(a)(ii).

         (f) Intellectual Property Licenses. 

                     (i)  (A) Seller will grant at the Closing to Buyer a
                          world-wide, irrevocable, exclusive, royalty-free
                          license (with a right to sublicense) under the
                          patents, or patents resulting from any applications or
                          disclosures, of the Seller Licensed Technology, and
                          any counterparts thereof, or any divisions,
                          substitutes, continuations, reissues or
                          re-examinations thereof, to make, have made, use,
                          import, sell or otherwise dispose of products, or to
                          practice any process in connection therewith solely in
                          the field of the Business (or any related extensions
                          or expansions of the Business); said

                          exclusive license being transferable solely in
                          connection with the sale of all or any part of
                          Buyer's business to which such patents relate. For
                          purposes of this Agreement, "Seller Licensed
                          Technology" means any Intellectual Property of Seller
                          or any of its Affiliates used by Seller or TSM in the
                          Business that is not transferred to Buyer hereunder.

                     (B)  Seller will grant at the Closing to Buyer a
                          world-wide, irrevocable, exclusive, royalty-free
                          license (with a right to sublicense) to use any
                          commercial or technical information relating to the
                          Seller Licensed Technology and owned or licensable by
                          Seller as of the Closing, solely in connection with
                          the field of the Business (or any related extensions
                          or expansions of the Business) and to transfer such
                          license solely in connection with the sale of all or
                          any part of Buyer's business to which the license
                          relates. To the extent that Buyer does not have copies
                          of any information or materials relating to the Seller
                          Licensed Technology, Seller will supply promptly to
                          the Buyer copies of any such information or materials.

                     (C)  Buyer acknowledges that, notwithstanding the licenses
                          of subsections (A) and (B), Seller and its Affiliates
                          retain and continue to hold unfettered rights,
                          including the rights to use, sublicense or sell all
                          Seller Licensed Technology without accountability, so
                          long as such rights are exercised solely in fields
                          outside the fields of the Business.

                     (D)  Seller represents and warrants (i) that it has the
                          full right to grant the licenses set forth in
                          subparagraphs (A) and (B) above; (ii) that to Seller's
                          knowledge, use of the Seller Licensed Technology as it
                          is currently used in the Business does not infringe or
                          violate the rights owned or held outside the United
                          States by any Third Person; (iii) that to Seller's
                          knowledge, use of the Seller Licensed Technology as it
                          is currently used in the Business does not infringe or
                          violate the rights owned or held in the Unites States
                          by any third Person; and (iv) that to Seller's
                          knowledge, there exist no facts that would cause any
                          of the properties licensed under subsections (A) and
                          (B) above to be invalid or unenforceable. Seller makes
                          no warranties regarding the scope of exclusivity
                          provided by any patent included in the Seller Licensed
                          Technology and no other warranty regarding validity or
                          enforceability of Seller Licensed Technology covered
                          by the licenses set forth in subsections (A) and (B).
                          The representations and warranties contained in this
                          section D shall be subject to the limitations and

                     (E)  As to the patents or patent applications covered by
                          the license set forth in subsection (A), Seller
                          (including its Affiliates) has no obligation to file
                          or prosecute any patent application or to maintain any
                          patents in force; provided that, in the event Seller
                          determines to discontinue payment of maintenance fees
                          on any issued

                          patent included in Seller Licensed Technology, Seller
                          shall provide Buyer timely written notice of such
                          determination. Upon the written request of Buyer,
                          Seller shall promptly (and in any event no later than
                          30 days from Buyer's written notice) execute and
                          deliver to Buyer an assignment of the issued patent
                          that is the subject of Seller's determination at no
                          additional cost. Any such assignment shall be subject
                          to a covenant not to sue in favor of Seller. Such
                          assignment may retain for Seller a right to use the
                          assigned patent solely in fields outside the fields
                          of the Business. 

                     (ii) (A) Buyer will grant at the Closing to Seller and its
                          Affiliates a world-wide, irrevocable, non-exclusive,
                          royalty-free license (without the right to
                          sublicense), under the patents, or patents resulting
                          from any applications or disclosures, of the Business
                          Licensed Technology, and any counterparts thereof, or
                          any divisions, substitutes, continuations, reissues or
                          re-examinations thereof, to make, have made, use,

                          license being transferable solely in connection with
                          the sale of all or any part of Seller's or any of its

                          Technology" means any Intellectual Property of Seller
                          that is transferred

(ii) Buyer shall place the Initial Purchase Price in escrow in accordance with
the terms of the Escrow Agreement.

1.       EMPLOYMENT ARRANGEMENTS, BENEFITS AND PENSION PLANS.

         (a) Employment. Buyer shall offer employment commencing as of the
Closing Date to the Employees listed on Schedule 6(l)(i). The Employees who
accept such an offer of employment by Buyer on the Closing Date are herein
referred to as "Continued Employees" and those who do not accept such offer are
herein referred to as "Retained Employees." Nothing contained in this Section
11(a) is intended to confer upon any Employee listed on Schedule 6(l)(i),
including, without limitation, any such Employee who becomes a Continued
Employee, any right to continued employment after the Closing Date.

         (b) Severance Benefits.

                  (i) Seller shall be solely responsible for and shall pay when
         due all direct and indirect Liabilities, claims, losses, damages, costs
         and expenses in respect of any claim of any Retained Employee, that
         such Retained Employee's employment has been terminated, either
         voluntarily or involuntarily, in conjunction with the transactions
         contemplated hereby, including, without limitation, any claim for
         severance pay, unemployment benefits or any other Liabilities, claims,
         losses, damages, costs and expenses (including interest, penalties and
         fees of legal counsel), asserted against, imposed upon or incurred by
         Buyer or any of its Affiliates or Seller or any of its Affiliates
         arising from or relating in any way to such claims (whether or not such
         claim is based on any severance policy, agreement, arrangement or
         program which may exist or arise under any 



                                      -68-
<PAGE>   73

         contract, employment agreement or under any federal, state or local
         Law).

                  (ii) Except as provided in Section 11(b)(iii) below, Buyer
         shall be solely responsible for and shall pay when due all direct and
         indirect Liabilities, claims, losses, damages, costs and expenses in
         respect of any claim of any Continued Employee that such Continued
         Employee's employment has been terminated, either voluntarily or
         involuntarily, in conjunction with or at any time after the Closing
         Date, including, without limitation, any claim for severance pay,
         unemployment benefits or any other Liabilities, claims, losses,
         damages, costs and expenses (including interest, penalties and fees of
         legal counsel), asserted against, imposed upon or incurred by Buyer or
         any of its Affiliates or Seller or any of its Affiliates arising from
         or relating in any way to such claim (whether or not such claim is
         based on any severance policy, agreement, arrangement or program which
         may exist or arise under any contract, employment agreement or under
         any federal, state or local Law).

                  (iii) If Buyer is deemed to have terminated any Continued
         Employee after the Closing Date solely as a result of Buyer's attempt
         to transfer such Continued Employee within six months after the Closing
         Date to a location other than such Continued Employee's location on the
         Closing Date (and such Continued Employee rejects such transfer and is
         terminated by Buyer as a result), then Seller will reimburse Buyer for
         all severance costs incurred by Buyer in connection with such
         termination, up to the amount Seller would have paid such employees as
         severance had they remained employees of Seller.

         Closing of any kind, character or description, including, without
         limitation, Buyer's obligations with respect to employee benefit plans
         of Buyer, accrued vacation/holiday, bonuses (except for any retention
         bonuses agreed to be paid to Continued Employees by Seller), or
         otherwise and except as noted in Section 11(b)(iii).

amounts payable after the Closing Date in respect of employee welfare and fringe
benefits paid or payable to Continued Employees under Buyer's welfare and fringe

                                      -78-
<PAGE>   83

         on the part of the Indemnified Party in notifying the Indemnifying
         Party shall relieve the Indemnifying Party from any obligation
         hereunder unless (and then solely to the extent) the Indemnifying Party
         is prejudiced thereby. 

                  (ii) The Indemnifying Party will have the right to defend the
         Indemnified Party against any Third Party Claim with counsel of its
         choice reasonably satisfactory to the Indemnified Party so long as (w)
         the Indemnifying Party notifies the Indemnified Party in writing within
         thirty (30) days after the Indemnified Party has given notice of such
         Third Party Claim that the Indemnifying Party will indemnify the
         Indemnified Party from and against any and all Damages, as the case may
         be, the Indemnified Party may suffer resulting from, arising out of,
         incurred with respect to, relating to, in the nature of, or caused by
         the Third Party Claim, (x) the Third Party Claim involves only money
         damages and does not seek an injunction or other equitable relief, (y)
         settlement of, or an adverse judgment with respect to, the Third Party
         Claim is not, in the good faith judgment of the Indemnified Party,
         likely to establish a precedential custom or practice materially
         adverse to the continuing business interests of the Indemnified Party,
         and (z) the Indemnifying Party conducts the defense of the Third Party
         Claim actively and diligently. 

                  (iii) So long as the Indemnifying Party is conducting the
         defense of the Third Party Claim in accordance with Section 14(c)(ii)
         hereof, (x) the Indemnified Party may retain separate co-counsel at its
         sole cost and expense and participate in the defense of the Third Party
         Claim, (y) the Indemnified Party will not consent to the entry of any
         judgment or enter into any settlement with respect to the Third Party
         Claim without the prior written 



                                      -79-
<PAGE>   84

         consent of the Indemnifying Party (not to be withheld or delayed
         unreasonably), (z) the Indemnifying Party will not consent to the entry
         of any judgment or enter into any settlement with respect to the Third
         Party Claim without the prior written consent of the Indemnified Party
         (not to be withheld or delayed unreasonably, provided that such consent
         shall not be deemed to be withheld unreasonably if any such judgment or
         settlement does not include as an unconditional term thereof the giving
         by the claimant or the plaintiff to the Indemnified Party of a release
         from all Liability in respect of the Third Party Claim giving rise
         thereto).

                  (iv) In the event any of the conditions in Section 14(c)(ii)
         hereof is or becomes unsatisfied: (x) the Indemnified Party may defend
         against, and consent to the entry of any judgment or enter into any
         settlement with respect to, the Third Party Claim in any manner it
         reasonably may deem appropriate; (y) the Indemnifying Party will
         reimburse the Indemnified Party promptly and periodically for the costs
         of defending against the Third Party Claim (including reasonable
         attorneys' fees and expenses); and (z) the Indemnifying Party will
         remain responsible for any and all Damages, as the case may be, the
         Indemnified Party may suffer resulting from, arising out of, incurred
         with respect to, relating to, in the nature of, or caused by the Third
         Party Claim. 

         (d) Limits on and Conditions of Indemnification. 

                  (i) Threshold Amount. Seller shall not be liable to indemnify
         Buyer for any Damages resulting from, arising out of, incurred with
         respect to, relating to, in the nature of, or caused by the matters set
         forth in Section 14(a)(i) hereof (other than with respect to the
         falsity, breach or



                                      -80-
<PAGE>   85

         inaccuracy or alleged falsity, breach or inaccuracy of the
         representations and warranties contained in Sections 6(a) through 6(e),
         6(i), 6(n) and 6(r) hereof) except to the extent that the aggregate
         amount of such Damages exceeds FIVE HUNDRED THOUSAND DOLLARS ($500,000)
         (the "Threshold Amount"). 

                  (ii) Maximum Amount. Seller shall not be liable to indemnify
         Buyer for any Damages based upon, arising out of, or otherwise in
         respect of the matters set forth in Section 14(a)(i) hereof once the
         aggregate amount of Damages actually paid by Seller to the Buyer Group
         with respect to such claims equals SIXTY MILLION DOLLARS ($60,000,000);
         provided, however, that the limitation contained in this clause shall
         not apply to any Damages based upon, arising out of, or otherwise in
         respect of any falsity, breach or inaccuracy of Seller's
         representations and warranties contained in Sections 6(a) through 6(e),
         6(i) and 6(n) hereof. 

                  (iii) Survival of Representations and Warranties. The
         respective representations and warranties of each Party contained
         herein or on any schedule attached hereto or in any other document
         delivered pursuant hereto shall survive for the period stated herein.
         The respective representations and warranties of each Party contained
         in this Agreement (other than the representations and warranties
         contained in Sections 6(a) through 6(e), 6(i), 6(n), 6(r) and 6(s)
         hereof) shall survive the execution and delivery of this Agreement, the
         consummation of the transactions contemplated hereby and the Closing
         Date and shall continue in full force and effect until eighteen (18)
         months after the Closing Date and then terminate and expire with
         respect to any theretofore unasserted claims arising out of or
         otherwise in respect of any falsity, breach or inaccuracy of such
         representations or warranties. The 



                                      -81-
<PAGE>   86

         representations and warranties with respect to Taxes contained in
         Section 6(n) hereof shall survive the execution and delivery of this
         Agreement, the consummation of the transactions contemplated hereby and
         the Closing Date until all applicable statutes of limitation (including
         any extension thereof) have expired and then expire with respect to any
         theretofore unasserted claims arising out of or otherwise in respect of
         any falsity, breach or inaccuracy of such representations or
         warranties. The representations and warranties with respect to employee
         benefits and environmental remediation contained in Sections 6(r) and
         6(s) hereof shall in each case survive the execution and delivery of
         this Agreement, the consummation of the transactions contemplated
         hereby and the Closing Date and shall continue in full force and effect
         until five years after the Closing Date and then expire with respect to

         warranties. The representations and warranties contained in Sections
         6(a) through 6(e) and 6(i) hereof shall in each case survive the

         transactions contemplated hereby and the Closing Date without time
         limitation. 

                  (iv) Survival of Indemnification Obligations. The
         indemnification obligations for all Damages relating to matters set
         forth in Sections 14(a)(i) and 14(b)(i) hereof shall survive the
         execution and delivery of this Agreement, the consummation of the
         transactions contemplated hereby and the Closing Date and continue in
         full force and effect thereafter to the extent set forth in Section
         14(d)(iii) hereof and then expire (other than as set forth in such
         Section 



                                      -82-
<PAGE>   87

         14(d)(iii)) with respect thereto. The indemnification obligations for
         all Damages related to matters set forth in Sections 14(a)(ii) and
         14(b)(ii) shall survive the execution and delivery of this Agreement,
         the consummation of the transactions contemplated hereby and the
         Closing Date and will terminate upon the expiration of the applicable
         statute of limitations. The indemnification obligations for all Damages
         related to matters set forth in Sections 14(a)(iii), 14(a)(iv),
         14(a)(v), 14(b)(iii), 14(b)(iv) and 14(b)(v) hereof shall survive the
         execution and delivery of this Agreement, the consummation of the
         transactions contemplated hereby and the Closing Date and continue in
         full force and effect thereafter without time limitation.

                  (v) Insurance Proceeds Limitation. No loss, Liability, damage
         or deficiency shall constitute Damages to any Party to the extent of
         any insurance proceeds actually received by such Party with respect to
         such loss, Liability, damage or deficiency.

                  (vi) Exclusive Remedy. Each of Buyer and Seller acknowledges
         and agrees that, except for claims of fraud or similar claims which as
         a matter of law can not be waived, its sole and exclusive remedy
         subsequent to Closing with respect to any and all claims for Damages
         covered by the indemnification provisions in Sections 14(a) and 14(b),
         as the case may be, shall (except as expressly provided in Section
         15(b)) be pursuant to the indemnification provisions set forth in this
         Section 14. In furtherance of the foregoing, except for claims of fraud
         or similar claims which as a matter of law can not be waived, each of
         Buyer and Seller hereby waives, to the fullest extent permitted under
         applicable Law, any and all rights, claims and causes of action it or
         any of its respective Affiliates 



                                      -83-
<PAGE>   88

         may have against the other Party or such other Party's Affiliates or
         any other member of the Seller Group or the Buyer Group, as the case
         may be, arising under or based upon any federal, state or local
         statute, Law, or common law or at equity but only to the extent they
         relate to the matters described in the immediately preceding sentence.

                  (vii) No Lost Profits or Consequential Damages. Neither Seller
         nor Buyer shall have any obligation to indemnify the other or any other
         Person (including, without limitation, any member of the Seller Group
         or the Buyer Group, as the case may be) under this Agreement against,
         or otherwise have any Liability under this Agreement with respect to,
         lost profits or consequential damages.

15.      RESTRICTIVE COVENANT.

         (a) Non-Compete. Seller agrees that, for a period of five (5) years
after the Closing Date, neither it nor any Person now or hereafter controlled by
it will, directly or indirectly, in any area of the world, enter into or engage
in or acquire control of more than a five percent (5%) interest in any business
engaged in development, manufacture, sale, maintenance or servicing of the
products and services of the Business set forth on Schedule 15(a) hereto
("Business Products and Services") or any derivatives of or improvements to such
products; provided, however, that if Seller or any Affiliate of Seller acquires
control of any business engaged in the development, manufacture or sale of
products or services that compete directly with the Business Products or
Services, Seller or any such Affiliate shall not be in violation of the covenant
contained in this Section 15(a) if Seller or such Affiliate divests the portion
of such business which develops, manufactures or sells products or services that



                                      -84-
<PAGE>   89

compete directly with the Business Products or Services as promptly as
practicable and in any event no later than eighteen (18) months following such
acquisition. 

         (b) Remedies. Seller hereby acknowledges that in the event of its
breach of the covenant contained in Section 15(a) hereof, money damages would be
an inadequate remedy. Accordingly, without prejudice to the rights of Buyer to
also seek such damages or other remedies available to it, Buyer may seek, and
Seller acknowledges and covenants that it will not contest the appropriateness
or the availability of, injunctive or other equitable relief in any proceeding
which Buyer may bring to enforce the covenant not to compete contained in
Section 15(a) hereof on its express and explicit terms. No waiver of any breach
of the covenant contained in Section 15(a) hereof shall be implied from
forbearance or failure of Buyer to take action thereon. 

         (c) Severability. Seller and Buyer agree that, if any provision of this
Section 15 should be adjudicated to be invalid or unenforceable, such provision
shall be deemed deleted herefrom with respect, and only with respect, to the
operation of such provision in the particular jurisdiction in which such
adjudication was made; provided, however, that to the extent any such provision
may be valid and enforceable in such jurisdiction by limitations on the scope of
the activities, geographical area or time period covered, Seller and Buyer each
hereby agree that such provision instead shall be deemed limited to the extent,
and only to the extent, necessary to make such provision enforceable to the
fullest extent permissible under the Laws and public policies in such
jurisdiction. 

         (d) Non-Exclusivity. The covenants contained in this Section 15 shall
be construed and enforced independently of any other provision of this Agreement
or any other understanding or agreement between the 



                                      -85-
<PAGE>   90

Parties, and the existence of any claim or cause of action of Seller against
Buyer (whether in connection with this Agreement or otherwise), of whatever
nature, shall not constitute a defense to the enforcement against a Seller of
the covenants contained herein.

16.      MISCELLANEOUS.

         (a) Successors and Assigns. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and
permitted assigns of the Parties. This Agreement may not be assigned by any

that Buyer shall remain responsible for the performance of its agreements and
obligations contained herein. 

         (b) Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original

waived in writing signed by the other party at any time by the Party entitled to
the benefits thereof. No waiver of any of the provisions of this Agreement shall
be deemed or shall constitute a waiver of such provision at any time in the
future or a waiver of any other provision hereof. 

         (e) Broker's Fees. Neither Buyer nor Seller has taken or will take any
action that would cause it or one or more of the other Parties to have 



                                      -86-
<PAGE>   91

any obligation or Liability to any Person for a finder's, broker's, agent's or

limitation. 

         (f) Expenses. Except as otherwise expressly provided for herein, Seller

herein to sections and schedules shall be to sections of and schedules to this
Agreement. Disclosure on any schedule to this Agreement of items that may or may
not be strictly required to be disclosed by this Agreement shall not be deemed
to imply that such items are material or that the inclusion of such items
creates a standard of materiality. All terms defined herein shall be equally
applicable to both the singular and plural forms thereof. 

         (p) No Representations or Warranties. Buyer acknowledges that none of
Seller or any of its Affiliates or any other Person has made any representation

                                  EABS UPGRADE

         The Upgrade Program is intended to address the potential failure of the
Closing Date ECP Manifolds in executing certain instructions. The Closing Date
ECP Manifolds contain a number of electronically activated, pneumatic switches
which are piloted to new positions by pressurized air. If the pilot air pressure
is not sufficient, the pneumatic switch may fail to change position or may stop
in an indeterminate state. Such failures may result in a reduction in braking
effort. The Upgrade Program is intended to increase the force acting upon a
pneumatic switch by increasing the surface area of the pneumatic switch. Such
increase will be achieved by reboring passages that house the shuttle valve
contained in each of the Closing Date ECP Manifolds.

         The Upgrade Program will require that two conditions be satisfied. One,
it must be conducted in a reasonably clean environment in order to guarantee the
quality and reliability of the ECP Manifold being modified. Second, the surfaces
that the machine tools reference must match the original dimensions.

         It is recognized that under some circumstances it may be more cost
effective to replace the Field ECP Manifolds than it may be to repair them as
described above. For example, it is likely that the Field ECP Manifolds have
been painted, which raises concerns with respect to the ability to repair such
Field ECP Manifolds while attempting to satisfy the above two conditions.
Depending upon the cost to remove the paint, it may be more cost effective to
replace the Field ECP Manifolds, than it may be to repair them as described
above.

         The Inventory ECP Manifolds will be repaired in the manner described
above rather than replaced.
