                  (xiii) subject to Section 5.10(a), any Liability of Sellers or
         any Sold Subsidiaries for patent infringement claims asserted in the
         name of Jerome H. Lemelson alone or as co-inventor or the Lemelson

         successors or assigns with respect to any of Sellers' businesses,
         including the Business, and for trademark or trade name

         infringement claims asserted in any way, including by way of
         declaratory judgment action, opposition proceeding, or infringement
         suit involving White Consolidated Industries, Inc.;

                  (xiv) Sellers' and Sold Subsidiaries' liabilities for
         outstanding checks issued on or before the Closing Date which (x) are
         drawn on bank accounts that are Excluded Assets and (y) have reduced
         Assumed Liabilities as of the Closing; and

                  (xv) any other Liabilities not assumed by Purchaser pursuant
         to the provisions of Section 2.3(a).

                  Except for Assumed Liabilities, neither Purchaser nor any of
its Affiliates is assuming, or in any other way becoming responsible for the
payment or performance of, any Liabilities of any of the Sellers, whether known
or unknown, accrued, absolute, contingent, changing, determinable,
indeterminable, liquidated, unliquidated or otherwise and whether due or to
become due or relating to any existing or prior act, omission, condition or
state of facts.

                  SECTION 2.4. PURCHASE PRICE. Subject to Section 2.5, the
purchase price for the Acquired Assets (the "Purchase Price") shall consist of

                  (a) the payment by Purchaser of $237,500,000 (the "Cash
Portion"), payable as set forth in Section 3.2(b); and

                  (b) the assumption by Purchaser and its Affiliates of the
Assumed Liabilities.

                  SECTION 2.5. PURCHASE PRICE ADJUSTMENT.

                  (a) Within 90 days after the Closing Date, CBS shall at its
expense prepare and deliver to Purchaser a statement of Working Capital (the
"Statement of Working Capital") and a statement of Net Assets (the "Statement of
Net Assets") as of the close of business on the Closing Date setting forth
Working Capital (as defined below) and Net Assets (as defined below),
respectively, together with separate special-purpose reports of CBS's
independent auditors to the effect that the Statement of Working Capital and the
Statement of Net Assets have been prepared and audited in compliance with the
requirements of this Section 2.5. The Statement of Working Capital and Statement
of Net Assets are collectively the "Statements."

                  During the 60-day period following Purchaser's receipt of the
Statements, Purchaser and its independent auditors shall be permitted to review
and make copies reasonably required of the working papers of CBS and its
independent auditors relating to the Statements and shall have reasonable access
to CBS representatives and its independent auditors.



                                       26
<PAGE>   38

The Statement of Working Capital shall become final and binding upon the parties
on the 60th day following delivery thereof, unless Purchaser gives written
notice of its disagreement with the Statement of Working Capital ("Notice of
Disagreement") to CBS prior to such date. Any Notice of Disagreement shall (A)
specify in reasonable detail the nature of any disagreement so asserted, (B)
only include disagreements based on mathematical errors or based on Working
Capital not being calculated in accordance with this Section 2.5, (C) only
include disagreements based on the Statement of Working Capital, (D) be
accompanied by a signed written confirmation by Purchaser that it has complied
with the covenants set forth in Section 2.5(e), and (E) if Purchaser's
independent auditors are engaged by Purchaser in connection with the preparation
of the Notice of Disagreement, be accompanied by a written confirmation of
Purchaser's independent auditors that they concur with each of the positions
taken by Purchaser in the Notice of Disagreement. If a Notice of Disagreement
complying with the preceding sentence is received by CBS in the period
specified, then the Statement of Working Capital (as revised in accordance with
clause (I) and (II) below) shall become final and binding upon the parties on
the earlier of (I) the date CBS and Purchaser resolve in writing any differences
they have with respect to the matters specified in the Notice of Disagreement or
(II) the date any disputed matters are finally resolved in writing by the
Accounting Firm (as defined below).

                  During the 60-day period following the delivery of a Notice of
Disagreement that complies with the preceding paragraph, CBS and Purchaser shall
seek in good faith to resolve in writing any differences which they may have
with respect to the matters specified in the Notice of Disagreement. During such
period, CBS and its independent auditors shall be permitted to review and make
copies reasonably required of the working papers of Purchaser and shall have
reasonable access to its representatives and its independent auditors, including
their working papers and make copies reasonably required relating to the
preparation of the Notice of Disagreement. If, at the end of such 60-day period,
CBS and Purchaser have not so resolved such differences, CBS and Purchaser shall
submit to an independent accounting firm (the "Accounting Firm") mutually
acceptable to the parties for review and resolution any and all matters which
remain in dispute and which were properly included in the Notice of
Disagreement. CBS and Purchaser shall use reasonable efforts to cause the
Accounting Firm to render a decision resolving the matters in dispute within 30
days following the submission of such matters to the Accounting Firm. CBS and
Purchaser agree that judgment may be entered upon the determination of the
Accounting Firm in any court having jurisdiction over the party against which
such determination is to be enforced. Except as specified in the following
sentence, the cost of any arbitration (including the fees and expenses of the
Accounting Firm) pursuant to this Section 2.5 shall be borne by CBS and
Purchaser in inverse proportion as they may prevail on matters resolved by the
Accounting Firm, which proportionate allocations shall also be determined by the
Accounting Firm at the time the determination of the Accounting Firm is rendered
on the merits of the matters submitted. The fees and expenses of CBS's
independent auditors incurred in connection with the issuance of



                                       27
<PAGE>   39

their special-purpose reportS relating to the Statements and review of any
Notice of Disagreement shall be borne by CBS, and the fees and expenses of
Purchaser's independent auditors incurred in connection with their review of the
Statements shall be borne by Purchaser.

                  (b) The Purchase Price shall be increased by the amount by
which Working Capital exceeds the Target Amount (as defined below), and the
Purchase Price shall be decreased by the amount by which Working Capital is less
than the Target Amount (the Purchase Price as so increased or decreased shall
hereinafter be referred to as the "Adjusted Purchase Price"). The Target Amount
shall be $(16,263,000). If the Purchase Price is less than the Adjusted Purchase
Price, Purchaser shall, and if the Purchase Price is greater than the Adjusted
Purchase Price, CBS shall, within 10 business days after the Statement of
Working Capital becomes final and binding upon the parties, make payment to the
other party by wire transfer in immediately available funds of the amount of
such difference, together with interest thereon at the three-month treasury bill
rate (as reported by The Wall Street Journal or, if not reported thereby, by
another authoritative source) in effect on the Closing Date plus .25% (the
"Rate"), calculated on the basis of the actual number of days elapsed over 365,
from the Closing Date to the date of actual payment, compounded annually.
Notwithstanding the foregoing provisions of this Section 2.5, if the Statement
of Working Capital delivered by CBS pursuant to Section 2.5(a) and any Notice of
Disagreement delivered by Purchaser pursuant to Section 2.5(a) both reflect a
calculation of Working Capital that if correct would require a payment by the
same party, then within 10 days after delivery of the Notice of Disagreement
that party shall make a payment to the other, in the manner and with interest as
provided elsewhere in this Section 2.5(b), in an amount equal to the lesser of
(i) the amount payable by that party pursuant to the calculation reflected in
the Statement of Working Capital and (ii) the amount payable by that party
pursuant to the calculation reflected in the Notice of Disagreement. Any amount
paid pursuant to the preceding sentence shall be applied against, and
correspondingly reduce, the amount otherwise payable under this Section 2.5(b).

                  (c) The term "Working Capital" shall mean Total Current Assets
minus Total Current liabilities (in each case as defined below). The Target
Amount equals Working Capital at December 31, 1997. The terms "Total Current
Assets" and "Total Current liabilities" shall mean the total current assets and
total current liabilities, respectively, of the Business (excluding amounts
related to the performance of services at Hanford, Idaho Falls, Fernald, and
Machinery Technology Division), determined in accordance with GAAP (it being
understood that (i) all Excluded Assets, (ii) all Excluded Liabilities, (iii)
all pension, postretirement, and postemployment (excluding restructuring
actions) benefit liabilities, (iv) deferred Income Taxes, and, (v) insurance
proceeds receivable classified as a current asset as of the Closing Date related
to the loss of any asset for which as of such date a replacement had not been
placed in service and (x) is of a type permitted or required by GAAP to be
recognized as a fixed asset on the books of the Business as of the Balance Sheet
date and (y) but for such loss



                                       28

prior to the Closing would be an Acquired Asset shall be excluded in determining
Total Current Assets and Total Current liabilities), using the same
methodologies, practices (including GAAP as in effect as of December 31, 1997),
accounting applications and assumptions (including discount rates and actuarial
assumptions), policies, valuations and estimation methodologies and judgments
(including those relating to balance sheet classification) as used in
determining the Target Amount as set forth in Schedule 2.5(a).

                  In calculating Working Capital or Net Assets, as the case may
be, no changes will be made in any valuation allowances, including but not
limited to contract estimates at completion, any inventory or accounts
receivable valuation allowances, any product warranty liabilities, environmental
liabilities, including decommissioning and decontamination liabilities, workers
compensation liabilities, or government rate and cost disallowance liabilities,
except to reflect specific identifiable events, facts and circumstances (other
than any such events relating to or arising as a result of the announcement of
the transactions contemplated by this Agreement) occurring between December 31,
1997 and the Closing Date. The parties agree that the adjustment contemplated by
this Section 2.5 is intended to show the change in Working Capital from the
Target Amount and that such change may only be measured if the calculation is
done in accordance with the preceding sentence and using the same methodologies,
practices (including GAAP as in effect as of December 31, 1997), accounting
applications and assumptions (including discount rates and actuarial
assumptions), policies, valuations and estimation methodologies and judgments
(including those relating to balance sheet classification) as used in
determining the Target Amount. The scope of the disputes to be resolved by the
Accounting Firm is limited to whether the Statement of Working Capital
calculations were done in accordance with the foregoing provisions of this
Section 2.5 and whether there were mathematical errors in the Statement of
Working Capital.

                  (d) The term "Net Assets" shall mean Total Assets minus Total
liabilities (in each case as defined below). The terms "Total Assets" and "Total
liabilities" shall mean the total assets and total liabilities, respectively, of
the Business (excluding amounts related to the performance of services at
Hanford, Idaho Falls, Fernald, and Machinery Technology Division), determined in
accordance with GAAP (it being understood that (i) all Excluded Assets, (ii) all
Excluded Liabilities, (iii) all pension, postretirement, and postemployment
(excluding restructuring actions) benefit liabilities, and (iv) deferred Income
Taxes shall be excluded in determining Total Assets and Total liabilities),
using the same methodologies, practices (including GAAP as in effect as of
December 31, 1997), accounting applications and assumptions (including discount
rates and actuarial assumptions), policies, valuations and estimation
methodologies and judgments (including those relating to balance sheet
classification) as used in determining the Balance Sheet.

                  (e) Without limiting anything contained in this Section 2.5,
no decision announced or event initiated by Purchaser prior to Closing with
respect to matters to take effect on or after the Closing Date shall be taken
into account in determining Closing



                                       29
<PAGE>   41

Working Capital or Closing Net Assets. Purchaser further agrees that following
the Closing, it shall not take any actions which would affect preparation and
audit of the Statements with respect to the accounting books and records of the
Business on which the Statements are to be based that are not consistent with
past practices. Purchaser shall cause the employees of the Business to cooperate
in the preparation of the Statements, including providing customary
certifications, including management representation letters, to CBS's
independent auditors.

                  (f) During the period of time from and after the Closing Date
through the resolution of any adjustment to the Purchase Price contemplated by
this Section 2.5, Purchaser shall cause the employees of the Business to afford
to CBS and any accountants, counsel or financial advisers retained by CBS in
connection with any adjustment to the Purchase Price contemplated by this
Section 2.5 on-site access reasonably required at all reasonable times to all
personnel, properties, books, contracts, records, schedules, analyses and
working papers of the Business.

acceleration of any obligation (except, to the extent provided in any such
program or plan, any acceleration of vesting under the Westinghouse Savings

a material benefit under, or result in the creation of any Lien upon any of the

                  (c) FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES.

                  (i) CBS has previously delivered to Purchaser the audited
         combined balance sheet (the "Balance Sheet") and related statements of
         income and cash flows of the Business (except as set forth on Schedule
         4.1(c)(i)(A)) as of and for the fiscal year ended December 31, 1997,
         together with the notes to such financial statements (collectively, the
         "Financial Statements"). The Financial Statements have been prepared
         from the books and records of CBS and its Subsidiaries relating to the
         Business and, except as described in the notes thereto or the
         independent auditors' report thereon, or otherwise indicated in the
         Financial Statements, have been prepared in accordance with GAAP
         consistently applied and present fairly, in all material respects the
         financial position, results of operations and cash flows of the
         Business (except as set forth on Schedule 4.1(c)(i)(A)) as at the dates
         and for the periods indicated. Schedule 4.1(c)(i)(B) sets forth a
         complete and correct reconciliation of the Financial Statements to the
         1997 balance sheet and income statement contained in the information
         memorandum dated March 1998 provided by CBS to potential purchasers
         (the "Memorandum").

                  (ii) Except (A) as disclosed, reflected or reserved against in
         the Balance Sheet and the notes thereto, (B) for items set forth in
         Schedules 4.1(c)(ii) and 4.1(e) or any other Schedule hereto, (C) for
         Liabilities incurred in the Ordinary Course of Business since the date
         of the Balance Sheet that would not reasonably be expected to have a
         Material Adverse Effect, (D) for Liabilities incurred in connection
         with this Agreement and the transactions contemplated hereby, (E) for
         Excluded Liabilities, (F) for Liabilities pursuant to any lawsuit,
         action or proceeding and (G) for Income Taxes, as of the date hereof
         there is no material liability related to the Business and none of the
         Sold Subsidiaries has any material liabilities, in each case of a
         nature required to be reflected on a balance sheet for the Business
         prepared in accordance with GAAP.

                  (iii) All Accounts Receivable reflected on the Balance Sheet
         and all Accounts Receivable that have arisen since the date of the
         Balance Sheet, (A) have arisen from bona fide sales transactions in the
         Ordinary Course of Business, and (B) represent valid and binding
         obligations due to the Sellers or Sold Subsidiaries, and are, and
         immediately following the Closing will be, enforceable in accordance
         with their terms (subject to the Bankruptcy Exception). Schedule
         4.1(c)(iii) lists any obligor which together with all of its Affiliates
         owed, as of May 31, 1998, amounts billed and uncollected by Sellers and
         the Sold Subsidiaries in an aggregate amount of $1,000,000 or more.
         Schedule 4.1(c)(iii) also sets forth a complete and correct list in all
         material respects of all set-offs or claims in respect of accounts
         receivable as of such date in an



                                       33
<PAGE>   45

         amount billed and uncollected with an invoice amount in excess of
         $100,000.

                  (iv) All the Inventory held for use or sale by any Seller or
         Sold Subsidiary consists of items that are of a quality and quantity
         usable and salable in the Ordinary Course of Business consistent with
         past practice, subject to normal and customary allowances in the
         industry for damage and outdated items.

                  (v) The order backlog information of the Business at the date
         of the Balance Sheet set forth on Schedule 4.1(c)(v) is true and
         correct in all material respects. The orders comprising the backlog of
         the Business reflect bona fide transactions entered into in the
         Ordinary Course of Business.

                  (vi) The financial projections contained in the Memorandum
         were prepared in good faith utilizing assumptions which management of
         CBS believed to be reasonable as of the time of such preparation (it
         being acknowledged by Purchaser that actual results may vary from such
         projections, and that such variances may be material).

                  (d) COMPLIANCE WITH APPLICABLE LAWS.

                  (i) Except as set forth on Schedule 4.1(d)(i), Sellers and the
         Sold Subsidiaries have complied with all Laws which relate to the
         Business and the Acquired Assets, except where the failure to so comply
         would not, individually or in the aggregate, reasonably be expected to
         have a Material Adverse Effect. Except as set forth in Schedule
         4.1(d)(i), since December 31, 1997, neither Sellers nor the Sold
         Subsidiaries have (i) received any written notice alleging any
         non-compliance with any such Laws which would reasonably be expected to
         have a Material Adverse Effect or (ii) received any written notice of
         any administrative, civil or criminal investigation or audit by any
         Governmental Authority relating to the Business which if adversely
         determined would reasonably be expected to have a Material Adverse
         Effect. None of the Sellers or the Sold Subsidiaries has at any time
         since December 31, 1994, (a) made any illegal payments for political
         contributions or any bribes, illegal kickback payments or other illegal
         payments except for those that are not material or (b) been
         disqualified, for any reason, from bidding on any public or private

         Assets, all Sellers and Sold Subsidiaries are currently, and will on
         the Closing Date be, in material compliance with the requirements of
         the Cost Accounting Standards, the Federal Acquisition Regulations and
         agency supplements, as applicable.

                  (e) LITIGATION; DECREES. Schedule 4.1(e) sets forth a list as
of the date of this Agreement of all pending lawsuits, actions and proceedings
to which any of the Sold Subsidiaries is a party or to which any of the Sellers

Liability, provided that this Section 4.1(e) shall not require disclosure of any
lawsuit, action or proceeding (i) in which one of the Sellers or the Sold
Subsidiaries is the plaintiff and no counterclaim or cross-claim has been, or is
likely, to be made against any of the Sellers or the Sold Subsidiaries, or (ii)
in which the amount at issue is less than $1,000,000. Except for matters set
forth in Schedule 4.1(e), as of the date hereof, there is no lawsuit, action or
proceeding pending, or, to the knowledge of CBS, threatened, against any of
Sellers or the Sold Subsidiaries seeking to delay or prevent, or otherwise
challenging, the transactions contemplated hereby. Neither Sellers nor the Sold
Subsidiaries are in default in any material respect under any judgment, order,
injunction or decree of any Governmental Authority entered against any of
Sellers or the Sold Subsidiaries and relating to the Business.

                  (f) TITLE TO ACQUIRED ASSETS; LEASEHOLD INTERESTS.

                  (i) Sellers have and will convey and transfer (subject to
         Sections 2.2(c) and 5.4) to Purchaser at Closing, good and valid title
         to the Acquired Assets, and the Sold Subsidiaries have good and valid
         title to all the Subsidiary Assets, in each case free and clear of all
         Liens, except Permitted Liens.

                  (ii) Sellers have and will convey and transfer to Purchaser at
         Closing the right to possess and use all the properties held by them
         under any lease, and the Sold Subsidiaries have the right to possess
         and use all the properties held by them under any lease, in each case
         (i) free and clear of all Liens, except Permitted Liens, and (ii)
         during the term, and subject to the provisions, of the leases as being
         applicable to such properties.

which Section 4.1(h) is applicable) or the Owned Real Property and Leased Real
Property (to which Section 4.1(g) is applicable).

                  (g) REAL PROPERTY.

                  (i) Owned Real Property. Schedule 1.1(b) is in all material
         respects a true, complete and correct list, as of the date hereof, of
         the street addresses and square footage of improvements on each parcel
         of Owned Real Property. The Owned Real Property constitutes all real
         property or interests in real property owned in fee by Sellers or the
         Sold Subsidiaries (other than any Excluded Assets) and primarily used
         in the operation of the Business as presently conducted. None of the
         Owned Real Property is Surplus Property. Each Seller and Sold
         Subsidiary has good and insurable fee title to all Owned Real Property
         owned by it free and clear of all Liens other than (A) Permitted Liens,
         (B) easements, covenants, rights-of-way and other encumbrances or
         restrictions of record, (C) zoning, building and other similar
         restrictions, (D) unrecorded easements, covenants, rights- of-way or
         other restrictions, (E) Liens that have been placed by any developer,
         landlord or other Person (other than Sellers or the Sold Subsidiaries)
         on property (other than Owned Real Property) over which any of Sellers
         or the Sold Subsidiaries has easement rights, none of which items set
         forth in clauses (B), (C), (D) or (E) above, individually or in the
         aggregate, materially impair the ability of the Sellers or the Sold
         Subsidiaries to use the property for the purposes for which it is
         currently being used in connection with the Business and, with respect
         to any Significant Real Property, none of which items set forth in
         clauses (B), (C), (D) or (E) would materially impair the continued use
         and operation thereof for the same uses and operations as those
         conducted at the present time or grant to any party any option or right
         to acquire or lease a material portion thereof. Except as set forth in
         Section 5.8, no brokerage or finders commissions shall be payable by
         Purchaser in connection with the conveyance of the Owned Real Property
         to Purchaser. No material portion of any of the Owned Real Property is
         leased by Sellers or the Sold Subsidiaries to any Person.

                  (ii) Leased Real Property. Schedule 1.1(a) is in all material
         respects a true, complete and correct list of all Leased Real Property.
         CBS shall provide Purchaser a list of all leases of Leased Real
         Property not later than 20 business days following the date of this
         Agreement. The Leased Real Property constitutes all real property
         leased by any Seller or Sold Subsidiary as Lessee (other than the
         Excluded Assets) and primarily used in the operation of the Business as
         presently conducted. None of the Leased Real Property is Surplus
         Property. With respect to each lease for Significant Real Property: (A)
         each such lease is valid and subsisting and in full force and effect as
         against the Seller or the Sold Subsidiary therein designated and, to
         the best of Sellers' knowledge, as against the landlord, and has not
         been amended, modified or supplemented except as set forth in Schedule
         1.1(a) or in a manner which would not reasonably be expected to
         materially reduce the benefits to Purchaser of the



                                       36
<PAGE>   48

         transactions contemplated by this Agreement; (B) no notice of a
         material default has been sent or received by any Seller or Sold
         Subsidiary under such lease which remains uncured and, to the best of
         Sellers' knowledge, no event has occurred and is continuing which, with
         notice or lapse of time or both, would constitute a material default by
         any Seller or Sold Subsidiary under such lease; and (C) the tenant is
         in occupancy of the space demised thereunder.

                  (iii) Significant Real Property. With respect to each
         Significant Real Property (which for purposes of this representation
         and warranty shall also include any Leased Real Property that is the
         subject of a sale/leaseback or similar arrangement in which any Seller
         or Sold Subsidiary is the primary occupant of the property demised
         thereunder): (A) CBS has no knowledge that any condemnation or eminent
         domain proceedings are pending with respect to any Significant Real
         Property; (B) each Significant Real Property is an independent unit
         that does not rely in any material respect on any facilities located on
         any property not included in such Significant Real Property to fulfill
         any municipal or governmental requirement or for the furnishing to such
         Significant Real Property or any essential building systems or
         utilities, other than facilities provided to the Significant Real
         Property pursuant to one or more valid easements; and (C) each
         Significant Real Property has access to a dedicated, public street,
         either by reason of such Significant Real Property abutting a
         dedicated, public street or by way of good and insurable appurtenant
         easement(s), and such access is adequate for the present use and
         operation thereof. No real estate tax certiorari proceedings are
         currently pending with respect to any Significant Real Property.

                  (iv) Subleases Affecting Leased Real Property. Schedule
         4.1(g)(iv) sets forth in all material respects a true, complete and
         correct list of all oral or written subleases (including all amendments
         and supplements thereto) demising space on the Leased Real Property
         leased by any of the Sellers or the Sold Subsidiaries under a lease
         (each, a "Sublease"). With respect to each Sublease for premises larger
         than 15,000 square feet of rentable space (each, a "Material
         Sublease"): (A) each such sublease is valid and subsisting and in full
         force and effect as against the Seller or the Sold Subsidiary therein
         designated and, to the best of the knowledge of CBS, as against the
         subtenant, and has not been amended, modified or supplemented expect as
         set forth in Schedule 4.1(g)(iv); and (B) no notice of a material
         default has been sent or received by any Seller or Sold Subsidiary
         under any Material Sublease which remains uncured and, to the best of
         the knowledge of CBS, no event has occurred and is continuing which,
         with notice or lapse of time or both, would constitute a material
         default by any Seller or Sold Subsidiary under any Material Sublease.

                  (h) INTELLECTUAL PROPERTY AND TECHNOLOGY.

                  Schedule 4.1(h)(i) sets forth a list, as of the date of this
         Agreement, of all material patents, patent applications, registered
         trademarks, trademark applications, registered service marks, service
         mark applications, registered copyrights and copyright applications
         owned by Sellers that relate primarily to the Business or owned by a
         Sold Subsidiary (except as otherwise provided by Section 5.16 and
         subject (i) to rights under development contracts under which the
         Intellectual Property and Technology may have been generated, (ii) to
         the rights of the United States government and (iii) to licenses
         granted to third parties) and included in the Acquired Assets or the
         Subsidiary Assets and, to the extent indicated on such Schedule, the
         Intellectual Property listed on Schedule 4.1(h)(i) has been duly
         registered in, filed in or issued by the United States Copyright Office
         or the United States Patent and Trademark Office, the appropriate
         offices in the various states of the United States and the appropriate
         offices of other jurisdictions. Except as set forth on Schedule
         4.1(h)(ii) and subject (i) to rights under development contracts under
         which the Intellectual Property and Technology may have been generated,
         (ii) to the rights of the United States government and (iii) to
         licenses granted to third parties, a Seller or a Sold Subsidiary is the
         sole and exclusive owner of all material Intellectual Property and
         material Technology (other than licenses) included in the Acquired
         Assets or the Subsidiary Assets, free and clear of any security
         interests. Except as set forth on Schedule 4.1(h)(iii), and subject (i)
         to rights under development contracts under which the Intellectual
         Property and Technology may have been generated, (ii) to the rights of
         the United States government and (iii) to licenses granted to third
         parties, a Seller or a Sold Subsidiary is the sole and exclusive owner
         of all right to sue and keep any damage awards for any past
         infringements by third parties of any material Intellectual Property or
         Technology (other than licenses). Except as set forth on Schedule
         4.1(h)(iv), since January 1, 1997, no Seller or Sold Subsidiary has
         received any written notice from any other Person challenging in any
         material respect the right of Sellers or the Sold Subsidiaries to use
         any of the material Intellectual Property or material Technology
         included in the Acquired Assets or the Subsidiary Assets or any rights
         thereunder. Sellers have taken measures, consistent with Sellers'
         corporate practice, to protect the secrecy, confidentiality and value
         of the material Technology included in the Acquired Assets. Except for
         the Excluded Assets (other than those described in clause (viii) of the
         definition of Excluded Assets) and subject to Section 2.2(c), Seller
         does not own any material intellectual property rights that it is not
         transferring to Purchaser that are required for Purchaser (together
         with the rights of Purchaser under the Purchaser Ancillary Documents,
         the Novation Agreements and the Purchaser Permits) to operate the
         Business after Closing in the manner in which it presently is operated.
         Except as set forth on Schedule 4.1(h)(v), since January 1, 1997, no
         Seller or Sold Subsidiary has made any claim in writing of a violation,
         infringement, misuse or misappropriation by others of their rights to
         or in connection with any material Intellectual Property or material
         Technology included in the Acquired Assets or the Subsidiary Assets,
         which



                                       38
<PAGE>   50

         claim is still pending. Except as set forth on Schedule 4.1(h)(vi), to
         the knowledge of CBS, as of the date of this Agreement, there is no
         pending or threatened claim by any third Person of a violation,
         infringement, misuse or misappropriation by any Seller or Sold
         Subsidiary of any intellectual property or technology owned by any
         third Person, or of the invalidity of any patent or registration of a
         copyright, trademark, servicemark or trade name included in the
         Acquired Assets or the Subsidiary Assets, which if adversely determined
         would reasonably be expected to have a Material Adverse Effect. Except
         as set forth on Schedule 4.1(h)(vii), there are no interferences or
         other contested proceedings, either pending or, to the knowledge of
         CBS, threatened, in the United States Copyright Office, the United
         States Patent and Trademark Office or any Governmental Authority
         relating to any pending application with respect to any material
         Intellectual Property. The use by Purchaser and its Affiliates of such
         names and marks as permitted under the licenses described in Section
         5.9(b) will not infringe on the rights of third parties. Except as
         provided in the immediately preceding sentence, nothing in this
         Agreement shall imply an indemnity for the infringement of third party
         intellectual property rights not within the knowledge of CBS.

                  (i) INSURANCE. Schedule 4.1(i) sets forth a list and brief
description (specifying the insurer, the policy number or covering note number
with respect to binders and the amount of any deductible, and the aggregate
limit, if any, of the insurer's liability thereunder) of all property and
liability policies or binders, including fire, liability, errors and omissions,
workers' compensation, vehicular and other property and liability insurance held

Assets, the Subsidiary Assets and the Business. Such policies and binders are
valid and enforceable in accordance with their terms in all material respects
(subject to the Bankruptcy Exception), and, as of the date hereof, are in full
force and effect. None of the Sellers or the Sold Subsidiaries is in default

has failed to give any material notice or present any material claim under any
such policy or binder. As of the date hereof, none of Sellers or the Sold
Subsidiaries has received any notice of cancellation or non-renewal of any such
policy or binder.

                  (j) CONTRACTS. (A) Except for Contracts listed on Schedule
4.1(j)(A), none of Sellers or any of the Sold Subsidiaries is a party to or
bound by any Contract that is (all such Contracts being referred to as "Material

                  (v) a Contract containing a covenant not to compete, other

         or

                  (x) a Contract providing for the formation of any joint

All of the Material Contracts are valid, subsisting, in full force and effect
and binding upon the Sellers or Sold Subsidiaries that are named as parties
thereto and, to the best knowledge of CBS, the other parties thereto in
accordance with their terms, subject to the qualifications that enforcement of
the rights and remedies created thereby is subject to: (A) bankruptcy,
insolvency, reorganization, moratorium and other laws of general application
affecting the rights and remedies of creditors and (B) general principles of
equity (regardless of whether such enforcement is considered in a proceeding in
equity or at law) (clauses (A) and (B) being referred to herein collectively as
the "Bankruptcy Exception"). Each of the respective Sellers or Sold Subsidiaries
has satisfied in full or provided for all of its liabilities and obligations
thereunder requiring performance prior to the date hereof in all material
respects, is not in default in any material respect under any of them, nor does
any condition exist that with notice or lapse of time or both would constitute
such a material default. To the best knowledge of CBS, as of the date hereof, no
other party to any such Material Contract is in default in any



                                       41
<PAGE>   53

material respect thereunder, nor does any condition exist as of the date hereof
that with notice or lapse of time or both would constitute such a material
default. This paragraph does not relate to real estate matters (to which Section
4.1(g) is applicable).

                  (B) With respect to all Government Contracts, none of the
managerial personnel (as such term is defined in the relevant Government
Contract) of the Sellers or any of the Sold Subsidiaries have engaged in any act
of willful misconduct or lack of good faith and none have failed to exercise
prudent business judgment so as to deprive any Seller or Sold Subsidiary of the
right to government reimbursement for Environmental Liabilities to third persons
or to any Governmental Authority either under the Department of Energy
Acquisition Regulations ((A) 48 C.F.R. Section 970.5204-31 (1997), (B) 48 C.F.R.
Section 970.5204-61 (1997), or (C) 48 C.F.R. Section 970.3101-3 (1997)) or under
the insurance, litigation and claims or similar clauses in any Government
Contract. None of such managerial personnel have engaged in any negligent,
unreasonable or other behavior so as to create any Environmental Liability in
connection with the performance of the Government Contracts so as to deprive any
Seller or Sold Subsidiary of the right to government reimbursement for
liabilities to third persons or to any Governmental Authority. For purposes of
this Section 4.1(j)(B), the terms "lack of good faith," "willful misconduct,"
and "prudent business judgment" shall have the meanings provided in 48 C.F.R.
Section 970.5204-31 (1997).

                  (C) With respect to each of the Government Contracts included
in the Acquired Assets, the Sellers and the Sold Subsidiaries have submitted to
the appropriate Administrative Contracting Officer ("ACO") forward pricing,
provisional indirect cost rate proposals and indirect cost claims on a timely
basis. Final negotiated indirect cost rate agreements closing indirect costs
years have been settled with the ACO through 1992. To the knowledge of CBS,
government audits of open years do not contain questioned costs that would
reasonably be expected to have a Material Adverse Effect. Set forth on Schedule
4.1(j)(C) is a true and correct description of all allegations, presently known
to CBS and made during the period from January 1, 1998 through the date hereof
by Federal agencies of willful misconduct or fraud as it relates to Federal
contracting activity.

                  (D) In connection with the pending governmental audit of the
1995 corporate general and administrative allocation by the Energy Systems
Business to EMD for Government Contracts, there are as of the date hereof no
findings that would reasonably be expected to materially change to the Energy
Systems Business indirect cost rate. There are adequate voluntary decrements
available to offset any audit findings sustained by the contracting officer in
connection with such audit or, if the voluntary decrements are inadequate to
offset any audit findings, any offsets in excess of such voluntary decrements
will not be material to the Business.

                  (k) SUFFICIENCY OF ACQUIRED ASSETS. Except as disclosed on
Schedule 4.1(k)



                                       42

and except for the Excluded Assets (other than those described in clause (viii)
of the definition of Excluded Assets), and subject to Section 2.2(c), the
Acquired Assets and the Subsidiary Assets on the Closing Date will comprise all
the assets owned by Sellers or the Sold Subsidiaries that, together with the
rights of Purchaser under the Purchaser Ancillary Documents, the Novation
Agreements and the Purchaser Permits, are necessary for (i) the conduct of the
Business in all material respects as presently conducted and (ii) the discharge
in all material respects of the Assumed Liabilities in the ordinary course of
business consistent with past practice in relation to the Business.

                  (l) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set forth
in the Schedules hereto, including Schedule 4.1(l), or as contemplated by this
Agreement, from the date of the Balance Sheet and until the date hereof Sellers
have conducted the Business in all material respects only in the Ordinary Course
of Business. Except as set forth in the Schedules hereto, including Schedule
4.1(l) or as contemplated by this Agreement, and except for changes (A) relating
to or resulting from seasonal changes or that generally affect to the same
extent all participants in the industries in which the Business operates, (B)
relating to or resulting from the public announcement of the transactions
contemplated by this Agreement or (C) relating to the identity of the Purchaser
or relating to or resulting from actions taken by Purchaser following the date
of this Agreement, from the date of the Balance Sheet there has not been any
Material Adverse Effect.

                  (m) EMPLOYEE BENEFITS.

                  (i) Schedule 4.1(m)(i) contains a list of all written Benefit
         Plans. Except as noted on Schedule 4.1(m)(i), CBS has made available to
         Purchaser true, complete and correct copies of (A) each Benefit Plan,
         (B) the most recent annual report on Form 5500 and attached schedules
         filed with the Internal Revenue Service with respect to each Benefit
         Plan (if any such report was required), (C) the most recent summary
         plan description for each Benefit Plan for which such a summary plan
         description is required, (D) each trust agreement and group annuity
         contract or other funding mechanism (other than insurance contracts)
         relating to any Benefit Plan, (E) the most recent audited financial
         statements and actuarial valuation reports with respect to each Benefit
         Plan, to the extent available, and (F) the most recent determination
         letter with respect to each Benefit Plan intended to qualify under
         Section 401(a) of the Code. Schedule 4.1(m)(i) separately identifies
         each Benefit Plan covering only employees or Former Employees of the
         Business and four defined benefit plans that will be spun-off from the
         Westinghouse Pension Plan covering (x) Bettis, West Valley and Waste
         Isolation Divisions of the Business (the "Individual Spun-Off Plans"),
         and (y) the Residual Divisions, (the "Residual Spun-Off Plan") which
         plans will cover Business Employees and Former Employees of such
         divisions (each a "Free Standing Plan"). At Purchaser's request,
         subject to CBS consent, not to be unreasonably withheld, CBS shall
         cause the Residual Spun-off Plan to take the form of two or more
         separate plans, as requested by Purchaser. In such event, whenever
         Residual Spun-off Plan is described in this Agreement, it shall refer
         to each of such plans, unless the context clearly contemplates
         otherwise. CBS will enter into contract modifications ("Contract
         Modifications") with the DOE or DOD, which modifications will be
         substantially in the form annexed to Schedule 4.1(m)(i) with respect to
         the Individual Spun-off Plans, the Westinghouse Executive Pension Plan
         and the CBS FAS 106 Plans, and will be in all material respects at
         least as protective to Purchaser as the form of agreement annexed to
         Schedule 4.1(m)(i).

                  (ii) Each Benefit Plan has been administered in all material
         respects in accordance with its terms and is in compliance in all
         material respects with the applicable provisions of ERISA, the Code and
         other applicable laws, rules and regulations. Except as set forth in
         Schedule 4.1(m)(ii), all material reports, returns and similar
         documents with respect to the Benefit Plans required to be filed with
         any Governmental Authority or distributed to any Benefit Plan
         participant have been duly and timely filed or distributed. Except as
         set forth in Schedule 4.1(m)(ii), there are no suits, actions,
         termination proceedings or other proceedings pending, or, to the
         knowledge of CBS, threatened against any Benefit Plan that relate to
         any Former Employees or employees of the Business who will become
         Business Employees and, to



                                       44
<PAGE>   56

         the knowledge of CBS and with respect to such employees, there are no
         investigations by any Governmental Authority or other claims (except
         claims for benefits payable in the normal operation of the Benefit
         Plans) pending or threatened against any Benefit Plan or asserting any
         rights to benefits under any Benefit Plan, which in each case is
         reasonably likely to be adversely determined and which, if adversely
         determined, would reasonably be expected to have an adverse effect on
         the Business.

                  (iii) Except as set forth in Schedule 4.1(m)(iii), (A) all
         contributions to, and payments from, the Benefit Plans that may have
         been required to be made in accordance with the Benefit Plans,
         collective bargaining agreements and, when applicable, Section 302 of
         ERISA or Section 412 of the Code, have been timely made, (B) there has
         been no application for or waiver of the minimum funding standards
         imposed by Section 412 of the Code with respect to any Pension Plan,
         and (C) no Pension Plan has an "accumulated funding deficiency" within
         the meaning of Section 412(a) of the Code as of the most recent plan
         year, except in each instance as would not reasonably be expected to
         have an adverse effect on the Business.

                  (iv) Except as set forth in Schedule 4.1(m)(iv), all Pension
         Plans have been the subject of determination letters from the Internal
         Revenue Service to the effect that such Pension Plans are qualified and
         exempt from Income Taxes under Sections 401(a) and 501(a),
         respectively, of the Code, and no such determination letter has been
         revoked nor, to the knowledge of CBS, has revocation been threatened.
         Except as set forth in Schedule 4.1(m)(iv), to the knowledge of CBS,
         (A) each such Pension Plan which is intended to be so qualified is so
         qualified, and (B) nothing has occurred, whether by action or failure
         to act, which would cause the loss of such qualification, except in
         each instance as would not reasonably be expected to have an adverse
         effect on the Business.

                  (v) Except as set forth in Schedule 4.1(m)(v), no "prohibited
         transaction" (as defined in Section 4975 of the Code or Section 406 of
         ERISA) has occurred that involves the assets of any Benefit Plan and
         that is reasonably likely to subject any Sold Subsidiary or any
         employees of the Business to the tax or penalty on prohibited
         transactions imposed by Section 4975 of ERISA or the sanctions imposed
         under Title I of ERISA. Except as set forth in Schedule 4.1(m)(v), none
         of the Pension Plans has been terminated nor have there been any
         "reportable events" (as defined in Section 4043 of ERISA and the
         regulations thereunder) with respect thereto and no event or condition
         exists (other than reportable events triggered solely by pending sales,
         dispositions and spin-offs by CBS of Subsidiaries, divisions and
         businesses, including the sale contemplated by this Agreement) which is
         likely to be deemed such a reportable event.



                                       45
<PAGE>   57

                  (vi) With respect to any Pension Plan subject to Title IV of
         ERISA, CBS and its Affiliates have not incurred any Liability to the
         Pension Benefit Guaranty Corporation, other than for payment of
         premiums, all of which have been paid when due, and other than any
         Liabilities that, individually or in the aggregate, would not be
         reasonably expected to have an adverse effect on the Business.

                  (vii) Except as set forth in Schedule 4.1(m)(vii), as of the
         most recent valuation date for each Pension Plan that is a defined
         benefit pension plan, there was not any amount of "unfunded benefit
         liabilities" (as defined in Section 4001(a)(18) of ERISA) under such
         Pension Plan.

                  (viii) Except as set forth in Schedule 4.1(m)(viii), at no
         time within the five years preceding the Closing Date has CBS or any of
         its Affiliates (including any of the Sold Subsidiaries) had any
         liability (including, without limitation, any withdrawal liability)
         with respect to, or been required to contribute to, any "multiemployer
         plan" (as defined in Section 4001(a)(3) of ERISA) for the benefit of
         any officers or employees of the Sold Subsidiaries or incurred any
         withdrawal liability, within the meaning of Section 4201 of ERISA, with
         respect to any such multiemployer plan, which liability has not been
         fully paid as of the date hereof, or announced an intention to
         withdraw, but not yet completed such withdrawal, from any such
         multiemployer plan.

                  (ix) Except as set forth in Schedule 4.1(m)(ix), no Former
         Employee or employee of the Business will become entitled to any
         material bonus, retirement, severance, job security or similar benefit
         or any materially enhanced benefit or the acceleration of payment of
         any material benefit contingent on the transactions contemplated hereby
         that, following the consummation of the transactions contemplated
         hereby, will be an obligation of (i) Purchaser or its Subsidiaries
         (including the Sold Subsidiaries) or (ii) CBS or its Affiliates.

                  (x) No amount payable to any Business Employee in connection
         with the transactions contemplated by this Agreement will fail to be
         deductible by a Sold Subsidiary by reason of Code Section 280G.

                  (xi) Except as disclosed on Schedule 4.1(m)(xi), since
         December 31, 1996, there have been no Benefit Plan amendments which
         have resulted in a material increase in liabilities of the Business.



                                       46
<PAGE>   58

                  (xii) Except as identified in Schedule 4.1(m)(xii), CBS and
         its Affiliates and the Benefit Plans are in material compliance with
         the requirements of Sections 4980B and 9801 et seq. of the Code and
         Sections 601 et seq. and 701 et seq. of ERISA.

                  (xiii) With respect to the year ended December 31, 1997, the
         applicable Sold Subsidiary employing Business Employees employed at
         Safe Sites of Colorado was or will be reimbursed by the applicable
         governmental agency for 100% of cash outlays for benefits paid to
         Former Employees (and to the extent applicable Business Employees)
         under nonqualified pension plans.

                  (n) ENVIRONMENTAL MATTERS. Except as disclosed on Schedule
4.1(n):

                  (i) For the purposes of this Section 4.1(n), "material" means
         any Loss which individually or in the aggregate with respect to the
         same set of facts, exceeds $2,500,000 and is not reimbursable by a
         Governmental Authority, and "Sellers" and "Sold Subsidiaries" include
         their directors, officers, agents, employees, representatives,
         consultants and shareholders;

                  (ii) Sellers and Sold Subsidiaries are in compliance in all
         material respects with all Environmental Laws governing the operations
         of the Business and the Acquired Assets, except where such failure to
         comply has not resulted and will not result in an Agency Action in
         respect of which the failure to comply would be material; and Sellers
         and Sold Subsidiaries are not currently liable for any penalties, fines
         or forfeitures for failure to comply with any of the foregoing, for
         which a failure to comply would be material;

                  (iii) Sellers and the Sold Subsidiaries severally hold, and
         are in material compliance with, all Permits required under the
         Environmental Laws for Sellers and the Sold Subsidiaries to conduct the
         Business, except where such failure to comply has not resulted and will
         not result in an Agency Action, a list of which Permits is identified
         in Schedule 4.1(n)(iii)(a); all such Permits are in full force and
         effect and all charges and fees relating thereto have been paid and, to
         the knowledge of CBS, there is no condition nor has any event occurred
         which constitutes, or with the giving of notice would constitute, a
         material violation of the terms of any such Permit; except as set forth
         in Schedule 4.1(n)(iii)(b), there are no material legal or
         administrative proceedings pending or, to the knowledge of CBS,
         threatened, which involve the validity, modification or breach of any
         such Permit or the entitlement of Seller or Sold Subsidiaries for any
         such Permit; and all applications for renewal of such Permits have been
         timely filed;



                                       47
<PAGE>   59

                  (iv) Except as set forth on Schedule 4.1(n)(iv), no
         Governmental Authority has indicated any unwillingness to grant any
         such consent required for the transfer or reissuance of any Permit to
         Purchaser;

         Sellers or Sold Subsidiaries have received nor, to the knowledge of
         CBS, is there any notice of any outstanding or threatened noncompliance
         order or notice of violation issued by any Governmental Authority
         administering the Environmental Laws in connection with the operation
         of the Business, the Premises or the Acquired Assets by any of the
         Sellers or the Sold Subsidiaries, or, to the knowledge of CBS, issued
         to their predecessors in interest, which has not been resolved to the
         satisfaction of the issuing Governmental Authority and which are
         material;

                  (vi) Except as set forth on Schedule 4.1(n)(vi), no Seller or
         Sold Subsidiary has entered into, agreed to or is subject to any Agency
         Action relating to compliance with any Environmental Law or to Remedial
         Action under any Environmental Law that would be material or would
         materially restrict Purchaser's operations of the Business; and Seller
         and Sold Subsidiaries are not in any material respect in noncompliance
         with, breach of or default under any such Agency Action;

                  (vii) To the knowledge of CBS, neither Sellers, in respect of
         the operations of the Business and the Acquired Assets, nor any of the
         Sold Subsidiaries, nor to the knowledge of CBS any predecessors in
         interest, have Released, transported, or disposed of any Hazardous
         Substance on, to, under or at any of the Premises, or any other
         property other than in a manner that would not cause a material Loss;
         and none of Sellers or the Sold Subsidiaries, nor to the knowledge of
         CBS, their predecessors in interest, have received any written notice
         prior to the date of this Agreement of the institution or pendency of
         any lawsuit, action, proceeding or investigation by any Person arising
         under any Environmental Law at any of the Premises, or any other
         property which is reasonably likely to be adversely determined and
         which if adversely determined would cause a material Loss, or which
         would require Remedial Action at any of the Premises, the costs of
         which would be material;

                  (viii) Except as disclosed in Schedule 4.1(n)(viii), in
         respect of the operations of the Business or the Acquired Assets, no
         Seller or Sold Subsidiary has received any notice and CBS has no
         knowledge of and has no reason to expect any enforcement order or
         notice of violation issued or given by any Governmental Authority or
         private party in which order or notice Sellers, Sold Subsidiaries or
         any of their predecessors in interest have been named as potentially
         responsible parties pursuant to CERCLA;

                  (ix) In respect of the operations of the Business or the
         Acquired Assets,



                                       48
<PAGE>   60

         Purchaser has been provided with an opportunity to review true, correct
         and complete copies of all relevant environmental investigations,
         studies, audits, tests, reports, reviews or other analyses conducted by
         or on behalf of, and that are in the possession of, any Seller or Sold
         Subsidiary in relation to any site or facility now or, in the case of
         any Sold Subsidiary, previously owned, operated or leased by any of
         them or any other property at which any Seller or Sold Subsidiary has
         or is alleged to have Environmental Liabilities; and

                  (x) None of Sellers or any Sold Subsidiary, in respect of the
         operations of the Business or the Acquired Assets, has agreed with any
         Governmental Authority pursuant to any Environmental Law to the
         imposition of any lien or limitation on the future use of any property
         that is an Acquired Asset.

                  (o) TAXES. Except as set forth on Schedule 4.1(o):

                  (i) Each of the Sellers and the Sold Subsidiaries has timely
         filed or has had filed on its behalf, after giving effect to any
         applicable extensions, all material Tax Returns required to be filed
         under applicable law with respect to the Acquired Assets or the income
         or operations of the Business, and all such Tax Returns were true,
         correct, and complete in all material respects. Each of the Sellers and
         the Sold Subsidiaries has timely paid or has had paid on its behalf,
         after giving effect to any applicable extensions, all Taxes shown as
         due on such Tax Returns.

                  (ii) No taxing authority has asserted in writing any material
         Tax deficiency that has not been paid or reserved for in accordance
         with GAAP with respect to the Acquired Assets, the Subsidiary Assets or
         the income or operations of the Business.

                  (iii) Except in connection with any consolidated, affiliated,
         or combined United States federal, state, or local Income Tax Return,
         none of the Sellers and none of the Sold Subsidiaries has requested any
         extension of time within which to file any Tax Return with respect to
         the Acquired Assets or the income or operation of the Business, which
         Tax Return has not since been filed.

                  (iv) Except in connection with any consolidated, affiliated,
         or combined United States federal, state, or local Income Tax Return,
         no Seller or Sold Subsidiary has executed any outstanding waivers or
         comparable consents regarding the application of the statute of
         limitations with respect to any Taxes or Tax Returns with respect to
         the Acquired Assets or the income or operation of the Business.

                  (v) None of the Acquired Assets or the Subsidiary Assets is

         person pursuant to the provisions of Code Section 168(f)(8) (as in
         effect prior to its amendment by the Tax Reform Act of 1986) or is
         "tax-exempt use property" within the meaning of Code Section 168(h).

                  (vi) No Sold Subsidiary is required to include in income any
         adjustment pursuant to Code Section 481(a) by reason of a voluntary
         change in accounting method initiated by such Sold Subsidiary, and the
         Internal Revenue Service has not proposed in writing any such
         adjustment or change in accounting method.

                  (vii) No material audits or other administrative proceedings
         or court proceedings are presently pending with regard to any Taxes or
         Tax Returns of any Seller (with respect to the Acquired Assets or the
         income or operation of the Business) or Sold Subsidiary. There is no
         pending claim by any authority of a jurisdiction where any of the

                  (p) SOLD SUBSIDIARIES. Except as set forth on Schedule 1.1(d)
(and except for Nominee Shares), all of the issued and outstanding shares of
capital stock of each Sold Subsidiary are owned, directly or indirectly,
beneficially and of record by one of the Sellers as set forth on Schedule
1.1(d), free and clear of all Liens, except as set forth on Schedule 1.1(d). For
purposes of this Section 4.1(p), "beneficial ownership" of any shares of capital
stock shall mean having or sharing the power to direct or control the voting or
disposition of such shares of capital stock. All of such outstanding shares of
capital stock have been duly and validly authorized and issued and are fully
paid and non-assessable. Except (i) for any Nominee Shares and (ii) as set forth
in Schedule 1.1(d), there are no shares of capital stock of or other equity
interests in any Sold Subsidiary outstanding. Except as set forth in Schedule
1.1(d), none of the shares of capital stock of or other equity interests in any
Sold Subsidiary has been issued in violation of, or are subject to, any purchase
option, call, right of first refusal or preemptive, subscription or similar
rights under any provision of applicable law, the certificate of incorporation
or by-laws (or comparable organizational documents) of any Sold Subsidiary or
any Contracts. Except as set forth in Schedule 1.1(d), there are no outstanding
warrants, options, rights, "phantom" stock rights, convertible or exchangeable
securities or other agreements to or instruments (other than this Agreement)
pursuant to which any Seller or any Sold Subsidiary is or may become obligated
to issue, sell, purchase, return or redeem any shares of capital stock of or
other equity interests in any Sold Subsidiary.

                  (q) LABOR MATTERS. Except as set forth in Schedule 4.1(q), (i)
there is no pending, and since December 31, 1997 through the date hereof there
has not been any, labor strike, work stoppage or lockout against any Seller in
connection with the Business, or any Sold Subsidiary, nor, to the knowledge of
CBS, is any such action threatened as of the date hereof, (ii) there is no
pending, and since December 31, 1997 through the date hereof there has not been
any, unfair labor practice charge or complaint against any Seller in connection
with the Business, or against any Sold Subsidiary, before the National Labor
Relations Board nor, to the knowledge of CBS, is any such charge or complaint
threatened as of the date hereof, and (iii) as of the date hereof, there are no
pending or, to the knowledge of CBS, threatened union grievances against any
Seller in connection with the Business, or any Sold Subsidiary, which, in the
case of clauses (i), (ii) and (iii), would, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. Except as disclosed on
Schedule 4.1(q)(iv), each of the Sellers and the Sold Subsidiaries has complied
in all material respects with its obligations related to, and is not in breach
in any material respect of or in default in any material respect under, any
collective bargaining or similar agreements to which any Seller (in connection
with the Business) or any Sold Subsidiary is a party. Except as set forth in
Schedule 4.1(q)(v), to the knowledge of CBS, there are no attempts presently
being made to organize any employees employed by any of the Sellers in
connection with the Business or any Sold Subsidiary.

                  (r) OUTSTANDING BIDS. Set forth in Schedule 4.1(r) is a
complete and correct list of all bids outstanding as of the date hereof for
Contracts by the Sellers or any Sold Subsidiaries in connection with the
Business, which Contracts, if awarded to the bidding Seller or Sold Subsidiary,
would involve aggregate expenditures or receipts in excess of $5,000,000. Except
as set forth on Schedule 4.1(1), no such bid reflects a material deviation from
the past bidding practices and procedures, including profit objectives, of the
Sellers and the Sold Subsidiaries, nor would any such bid (determined solely on
the basis of the projections of the applicable Seller or Sold Subsidiary as of
the time such bid was made) result in a loss to the applicable Seller or Sold
Subsidiary.

                  (s) MAJOR SUPPLIERS.

                  (i) Schedule 4.1(s) sets forth the name of, and a brief
         description of the goods or services supplied by, the twenty largest
         suppliers of goods or services to the Business (based upon amounts paid
         by the Sellers and the Sold Subsidiaries during the twelve-month period
         ending December 31, 1997); and

                  (ii)     Except to the extent set forth in Schedule 4.1(s),

                  (A)      since December 31, 1997 through the date hereof, no
                           change has occurred in the business relationship of
                           the Sellers or the Sold Subsidiaries with any
                           supplier listed on Schedule 4.1(s), the result of
                           which would reasonably be expected to have a Material
                           Adverse Effect;

                  (B)      none of the Sellers of the Sold Subsidiaries has
                           received prior to the date hereof notice from any
                           supplier listed on Schedule 4.1(s), to the effect
                           that any such supplier intends to cease, or make a
                           material reduction in its supply or goods or services
                           to, the Business; and

                  (C)      without limiting the generality of the foregoing,
                           none of the Sellers or the Sold Subsidiaries has
                           received prior to the date hereof written notice in
                           respect of any Government Contract that such
                           Government Contract is proposed to be rebid or that
                           the Sellers or Sold Subsidiaries will not be
                           considered for any follow-on work relating to such
                           Government Contract.

                  (t)      YEAR 2000.

                  (i)      The Sellers and the Sold Subsidiaries have developed
         and are executing a plan with respect to Year 2000 readiness (the "Year
         2000 Plan"). The Sellers have provided Purchaser with a copy of the
         Year 2000 Plan and have provided a report on



                                       52
<PAGE>   64

         the status of the Year 2000 Plan through June 13, 1998 that is accurate
         in all material respects.

                  (ii) The Year 2000 Plan address the Year 2000 issues which to
         the knowledge of CBS are material to the Sellers and the Sold
         Subsidiaries, including internal information systems risks, embedded
         circuitry risks and third party risks. Except as provided above and in
         Section 5.27, CBS makes no representations or warranties with respect
         to the capability of any of the equipment, systems, software, data or
         databases relating to the Business to adapt, accommodate or respond to
         the year 2000 and thereafter ("Year 2000 Compliance"), or with respect
         to the absence of Liabilities, contingent or otherwise, arising from or
         related to Year 2000 Compliance.

                  (u) TANGIBLE PROPERTY. All tangible personal property (other
than Inventory), including, without limitation, equipment, furniture, leasehold
improvements, fixtures, vehicles, structures, any related capitalized items and
other similar tangible property, in each case owned or leased by any of the
Sellers or Sold Subsidiaries and material to its business is in good operating
condition (normal wear and tear excepted), subject to continued repair and
replacement in accordance with past practice.

                  SECTION 4.2. REPRESENTATIONS AND WARRANTIES OF PURCHASER.

than, in the case of clause (iii) above, any such conflicts, violations,
defaults, rights or Liens that, individually or in the aggregate, would not
materially impair the ability of Purchaser to perform its obligations under this
Agreement. No consent, approval, license, permit, order or authorization of, or
registration, declaration or filing with, any Governmental Authority is required

by Purchaser and CBS, (iii) the medical records pertaining to any employee or
former employee of the Business until after the Closing or (iv) any "Classified
Information" other than in compliance with the DIS Industrial Security
Regulations, the DIS Industrial Security Manual and any other applicable
government security regulations. CBS shall cooperate reasonably with Purchaser
in connection with any request to make available to Purchaser and its
representatives, customers and suppliers of the Business, and to arrange and
participate in meetings between Purchaser and its representatives and such
customers and suppliers, for the purpose, among other things, of verifying the
information furnished to Purchaser, developing transition plans and integrating
the operations of the Business with the operations of Purchaser and its
Affiliates provided that (i) such cooperation does not unnecessarily interfere
with the operation of the GESCO Businesses or any other business of CBS and (ii)
Purchaser shall reimburse CBS upon request as incurred for any expenses incurred
in connection with such cooperation. All requests for information, to visit
facilities or to meet with Sellers' representatives shall be made in writing and
directed to and coordinated with the person(s) designated to Purchaser from time
to time by CBS as the GESCO Coordinator(s). Purchaser acknowledges that any
information being provided to it or its representatives by Sellers pursuant to
or in connection with this Agreement is subject to the terms of confidentiality
agreements between each of MK and

BNFL and CBS dated March 19, 1998 and March 13, 1998, respectively (the
"Confidentiality Agreements"), which terms are incorporated herein by reference.
CBS shall use its commercially reasonable efforts to, and to cause its
Affiliates to, enforce the respective terms of the confidentiality agreements
entered into with other prospective purchasers in connection with the proposed
sale of the GESCO Businesses (including requesting that such other prospective
purchasers return or destroy confidential information to the extent required to
do so as provided therein). Notwithstanding anything to the contrary contained
in paragraph 15 thereof, the Confidentiality Agreements and the obligations not
to use or disclose and to return on request or destroy Confidential Information
(as defined in the Confidentiality Agreements) shall terminate on the fifth
anniversary of the Closing Date. Nothing contained herein is intended to limit
or restrict Purchaser's use or disclosure of Confidential Information concerning
the Business following the Closing. No investigation by Purchaser shall diminish
or obviate any other representations, warranties, covenants or agreements of CBS
under this Agreement.

                  (b) During the period prior to the Closing, at the request of
Purchaser, CBS shall, and shall cause its and the other Sellers' employees to,
cooperate reasonably with Purchaser and its representatives in connection with
the preparation of such financial statements for the Business as may be required
in connection with the preparation by an applicable Affiliate of Purchaser of a
Current Report on Form 8-K relating to the transactions contemplated hereby;
provided that (i) such cooperation does not interfere with the operation of the
GESCO Businesses or any other business of CBS and (ii) Purchaser shall reimburse
CBS upon request as incurred for any expenses incurred in connection with such
cooperation.

                  (c) Prior to the Closing, CBS will deliver to Purchaser a
complete and correct list of all bank accounts of each of the Sold Subsidiaries,
and all persons having signing authority with respect thereto.

                  SECTION 5.3. GOVERNMENTAL APPROVALS, ETC.

                  (a) Each of Purchaser and CBS shall as promptly as
practicable, (i) but in no event later than 10 business days following the
execution and delivery of this Agreement, file with the United States Federal
Trade Commission and the United States Department of Justice the notification
and report form under the HSR Act required for the transactions contemplated
hereby and, thereafter, any supplemental information requested in connection
therewith pursuant to the HSR Act and (ii) but in no event later than 20
business days following the execution and delivery of this Agreement file with
the Committee on Foreign Investment in the United States the voluntary
notification under the Exon-Florio Amendment for the transactions contemplated
hereby. Each of Purchaser and CBS shall as promptly as practicable comply with
any other Laws of any country which are applicable to any of the transactions
contemplated hereby and pursuant to which any consent, approval, order or



                                       59
<PAGE>   71

authorization of, or registration, declaration or filing with, any Governmental
Authority or any other Person in connection with such transactions is necessary.
Each of Purchaser and CBS shall furnish to the other such necessary information
and reasonable assistance as the other may request in connection with its
preparation of any filing, registration or declaration which is necessary under
the HSR Act or any other such Laws. Purchaser and CBS shall keep each other
apprised of the status of any communications with, and any inquiries or requests
for additional information from, any Governmental Authority, and shall comply
promptly with any such inquiry or request. Purchaser and CBS shall use their
best efforts and take all necessary action to obtain any clearance under the HSR
Act, the Exon-Florio Amendment or any other consent, approval, order or
authorization of any Governmental Authority, necessary in connection with the
transactions contemplated hereby or to resolve any objections which may be
asserted by any Governmental Authority with respect to the transactions
contemplated hereby.

                  (b) Subject to the terms and conditions of this Agreement,
each party shall use its best efforts to cause the Closing to occur as promptly
as practicable, including (i) as contemplated by Section 5.3(a) or 5.4, (ii)
defending against any lawsuits, actions or proceedings, judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby, including seeking to prevent the entry or
imposition of any preliminary injunction, temporary restraining order, stay or
other legal restraint or prohibition by any court or other Governmental
Authority and to appeal and seek to have vacated or reversed as promptly as
possible any such injunction, order, stay or other restraint or prohibition that
is not yet final and nonappealable, provided, however, that none of Sellers nor
Purchaser nor their Affiliates shall be required to make any material monetary
expenditure, commence or be a plaintiff in any litigation or offer or grant any
material accommodation (financial or otherwise) to any third Person.

                  (c) Purchaser shall use its commercially reasonable efforts to
obtain as promptly as practicable all permits, licenses, franchises, approvals,
consents and authorizations by or of Governmental Authorities required by Law or
Contract for Purchaser to conduct the Business following the Closing and to own
the Acquired Assets (each, a "Purchaser Permit"), and CBS shall, and shall cause
the other Sellers and the Sold Subsidiaries to, cooperate with Purchaser in
connection therewith. Notwithstanding the foregoing, neither CBS nor Purchaser
shall be required to expend any material sum or agree to a material concession
to any Governmental Authority to obtain, or, in the case of CBS, to assist
Purchaser to obtain, as the case may be, any such Purchaser Permit. Purchaser
acknowledges that certain facilities owned or serviced by the Business and
certain related documents, records and information are classified for United
States government security purposes as high as the level of "Top Secret," which
may require, in addition to any Purchaser Permits required under applicable Law
to conduct the Business at such facilities, the employment of individuals
holding United States government security clearances as high as the level of
"Top Secret."



                                       60
<PAGE>   72

Notwithstanding anything to the contrary in this Agreement, CBS shall not be
required to provide access to such facilities or any such related documents,
records or information to any representative or employee of Purchaser unless
such individual presents evidence reasonably satisfactory to CBS of such
individual's security clearance meeting the security clearance level prescribed
for such access.

                  SECTION 5.4. NOVATIONS OF GOVERNMENT CONTRACTS AND THIRD PARTY
CONSENTS.

                  (a) As soon as practicable following the execution of this
Agreement, CBS shall prepare (with Purchaser's assistance, as necessary), in
accordance with Federal Acquisition Regulations Part 42, Paragraph 42.12 and any
applicable agency regulations or policies, a written request for the novation of
the Government Contracts meeting the requirements of the Federal Acquisition
Regulations Part 42, as reasonably interpreted by the Responsible Contracting
Officer (as such term is defined in Federal Acquisition Regulations Part 42,
Paragraph 42.1202(a)). The request for novation shall be submitted by CBS to
each Responsible Contracting Officer, for the United States government (or, in
the case of Government Contracts not subject to the Federal Acquisition
Regulations, Purchaser and CBS shall cooperate in seeking to cause the
applicable Governmental Authority) to (i) recognize Purchaser as CBS's successor
in interest to the Government Contracts and all the Acquired Assets used in the
performance of the Government Contracts and (ii) enter into one or more novation
agreements (collectively, "Novation Agreements") in form and substance
reasonably satisfactory to Purchaser and CBS and their respective counsel,
pursuant to which all of CBS's right, title and interest in and to, and all of
CBS's Liabilities under, each such Government Contract shall be validly
conveyed, transferred and assigned and novated to Purchaser by all parties
thereto. Purchaser shall provide to CBS promptly any information regarding
Purchaser required in connection with such request.

                  (b) CBS and Purchaser will cooperate and use their respective
commercially reasonable efforts to obtain as promptly as practicable (i) all
consents, approvals and waivers (A) required for the purpose of processing,
entering into and completing the Novation Agreements with regard to any of the
Government Contracts, including responding to any requests for information from
the United States government with regard to such Novation Agreements, or (B)
required by third Persons to transfer the Contracts, Intellectual Property,
Technology and the capital stock of the Sold Subsidiaries to Purchaser in a
manner that will avoid any default, conflict, or termination of rights under the
Contracts, Intellectual Property and Technology and (ii) without limiting the
provisions of clause (B) above, novations of all Contracts other than Government
Contracts. Notwithstanding anything to the contrary in this Agreement, nothing
in this Section 5.4 shall require Sellers or Purchaser to expend any material
sum, make a material financial commitment or grant or agree to any material
concession to any third Person to obtain any such consent, approval, waiver or
novation.



                                       61
<PAGE>   73

                  (c) If any and all consents, approvals or waivers necessary
for the assignment, transfer or novation of any Contract, Intellectual Property
or Technology, or any claim, right or benefit arising thereunder or resulting
therefrom, or consents relating to a change in control of any Sold Subsidiary,
shall not have been obtained prior to the Closing Date, then as of the Closing,
this Agreement, if permitted by Law, shall constitute full and equitable
assignment by Sellers to Purchaser of all of Sellers' right, title and interest
in and to, and all of Sellers' obligations and liabilities under, such
Contracts, Intellectual Property and Technology, and, in the case of such
Contracts, Purchaser shall be deemed Sellers' agent for purpose of completing,
fulfilling and discharging all of Sellers' obligations and liabilities under any
such Contract. The parties shall take all necessary steps and actions to provide
Purchaser with the benefits of such Contracts, Intellectual Property and
Technology, and, in the case of such Contracts, to relieve Sellers of the
performance and other obligations and liabilities thereunder, including entry
into subcontracts for the performance thereof. Purchaser agrees to pay, perform
and discharge, and, pursuant to Section 8.2, indemnify Sellers against and hold
Sellers harmless from, all obligations and liabilities of Sellers relating to
such performance or failure to perform under such Contracts, including any
related guarantees.

                  (d) If Sellers shall be unable to make the equitable
assignment described in Section 5.4(b), or if such attempted assignment would
adversely affect the rights of Sellers or Purchaser under such Contract,
Intellectual Property or Technology, or would not assign all of Sellers' rights
thereunder at the Closing, Sellers and Purchaser shall continue to cooperate and
use all reasonable efforts to provide Purchaser with all such rights. To the
extent that any such consents and waivers are not obtained, or until the
impediments to such assignment are resolved, Sellers shall use all reasonable
efforts (without the expenditure, in the aggregate, of any material sum) to the
extent permitted by Law to (i) provide to Purchaser, at the request of
Purchaser, the benefits of any such Contract or of any such Intellectual
Property or Technology, to the extent related to the Business, (ii) cooperate in
any lawful arrangement designed to provide such benefits to Purchaser and (iii)
enforce, at the request of and for the account of Purchaser, any rights of
Sellers arising from any such Contract, Intellectual Property or Technology
against any third Person including the right to elect to terminate in accordance
with the terms thereof upon the advice of Purchaser. To the extent that
Purchaser is provided the benefits (including payment rights) of any Contract,
Intellectual Property or Technology referred to herein (whether from Sellers or
otherwise), (i) Purchaser shall perform for the benefit of any third Person the
obligations of Sellers thereunder or in connection therewith, and (ii) Purchaser
agrees to pay, perform and discharge, and, pursuant to Section 8.2, indemnify
Sellers against and hold Sellers harmless from, all obligations and liabilities
of Sellers relating to such performance or failure to perform, and in the event
of a failure of such indemnity, Sellers shall cease to be obligated under this
Agreement in respect of the Contract, Intellectual Property or Technology which
is the subject of such failure.

                  (e) Without limiting the generality of Section 5.10, from the
Closing Date until, with respect to each Government Contract, the sixth year
following the earlier of the release date or notice of final payment for such
Government Contract, Purchaser agrees to provide CBS and its accountants,
counsel and other representatives access, during normal business hours, to such
information, personnel and assistance relating to the performance by Purchaser
of the Government Contracts and its respective obligations under the Novation
Agreements as CBS shall reasonably request from time to time.

                  SECTION 5.5. EMPLOYEE MATTERS.

                  (a) EMPLOYEE MATTERS.

                  (i) Continuation of Employment. Purchaser shall offer
         employment to (or cause a Sold Subsidiary to continue to employ) each
         employee of the Business (including any individual whose principal
         place of employment is on the Premises, who primarily renders services
         on behalf of the Business and whose compensation cost is borne
         primarily by the Business) who is actively at work, on vacation or on
         short-term disability (including salary continuation and extension)
         leave on the Closing Date (each a "Business Employee"). "Business
         Employee" shall not include any employee working at the Closing Date at
         locations listed in Section 2.2(b)(xv). Each employee or former
         employee who primarily rendered services on behalf of the Business and
         who is not actively at work on the Closing Date due to leave of
         absence, long-term disability leave, military leave or layoff, and who
         in the case of an employee on long-term disability was last actively
         employed within two years of the Closing Date, and in the case of an
         employee on a leave of absence or layoff was last employed within five
         years of the Closing Date and in each case has recall rights ("Recall
         Rights") under the work rules of the Business, a collective bargaining
         agreement or applicable law (collectively, "Inactive Employees"), shall
         be offered active employment by Purchaser pursuant to the Recall
         Rights. Inactive Employee shall not include any employee who last
         worked at locations listed in Section 2.2(b)(xv). Upon such offer and
         acceptance and commencement of active employment, each such Inactive
         Employee shall be considered a Business Employee effective as of the
         first date of return to work. CBS shall deliver a schedule to Purchaser
         of anticipated Business Employees and Inactive Employees and with
         respect to the latter their designated status as of the Closing Date
         and their entitlements, 15 days before the Closing Date. Such schedule
         shall be updated by CBS as soon as practical after the Closing Date.
         Any employee of Sellers or their Affiliates who is not otherwise a
         Business Employee but who is offered and accepts employment by
         Purchaser, pursuant to mutual agreement with the Sellers, during the
         six months following the Closing Date shall be deemed to be a Business
         Employee as of the date of actual employment with the Purchaser.
         Purchaser shall not offer employment to any employee of any Seller
         during such six-month period without the consent of such Seller (other
         than as provided for herein).

                  (ii) Continuation of Compensation and Benefits.
         Notwithstanding the more specific provisions set forth in this Section
         5.5, Purchaser shall provide or shall cause a Subsidiary to provide,
         compensation and written benefit plans and arrangements which in the
         aggregate are comparable (but in no event taking into account any
         equity-based compensation (including options) and opportunity to invest
         in securities of CBS under



                                       64
<PAGE>   76

         the CBS Stock Plan or the Westinghouse Savings Program, provided that
         with respect to Business Employees, the match formula under the
         Westinghouse Savings Program shall be considered when determining
         comparability) to the compensation and written Benefit Plans (See
         Schedule 4.1(m)(i)) in effect for Business Employees on the date of
         this Agreement ("Comparable Benefits") for a period of not less than
         one year following the Closing Date (or, in the case of Business
         Employees who are subject to a collective bargaining agreement, the
         period required therein) (the "Benefits Maintenance Period").
         Comparability for the purpose of determining Comparable Benefits shall
         be assessed in terms of total dollar value (or such other measurement
         utilized by the consultant) to Business Employees in the aggregate.
         Notwithstanding the above, with respect to Business Employees who are
         executives, the Purchaser shall provide long-term incentives which
         provide benefits generally comparable in value to long-term incentive
         plans of Sellers. No later than 15 days prior to the Closing Date
         Purchaser shall either (1) commit to CBS in writing to provide for
         Business Employees for the Benefit Maintenance Period substantially
         identical compensation and benefits to that provided by CBS and
         Affiliates to Business Employees (without regard to the equity-based
         compensation and the form of long-term incentive benefits) with CBS to
         consent to the determination of substantially identical benefits, which
         consent shall not be unreasonably withheld or (2) deliver to CBS a
         letter from an independent consulting firm reasonably acceptable to CBS
         stating that the compensation, benefits and benefit arrangements
         offered by Purchaser to the Business Employees pursuant to this Section
         are Comparable Benefits.

                  (b) ACCRUED VACATION. Purchaser shall credit each Business
Employee with the unused vacation days and any personal and sickness days earned
in accordance with the vacation and personnel policies and collective bargaining
agreements of CBS or the Sold Subsidiaries in effect as of the Closing Date,
provided that an appropriate adjustment shall be made in the event of any cash
payment required to be made by either Purchaser or Sellers as a result of the
transaction contemplated by this Agreement. CBS shall provide to Purchaser at
the Closing Date such schedules as CBS maintains and such other information as
reasonably necessary to calculate such benefits.

                  (c) PENSION PLAN. Effective as of the Closing Date, Purchaser
or the applicable Sold Subsidiary shall assume the Individual Spun-Off Plans and
the Residual Spun-Off Plan (subject to the provisions of Sections 5.5(n) (the
"Assumed Pension Plans")). Purchaser shall continue the Assumed Pension Plans
without adverse effect to the Business Employees for the Benefits Maintenance
Period and shall credit service of Business Employees with Sellers and Sold
Subsidiaries for purposes of eligibility, vesting and retirement eligibility in
all pension plans (within the meaning of Section 3(2) of ERISA) in which such
Business Employees participate.



                                       65
<PAGE>   77

                  (d) SAVINGS PLAN. (i) Effective as of the Closing Date,
Purchaser shall adopt or have in effect a defined contribution plan that
includes a qualified cash or deferred arrangement within the meaning of Section
401(k) of the Code ("Purchaser's 401(k) Plan") which offers benefits to Business
Employees eligible to participate in the Westinghouse Savings Program (the
"WELCO Savings Program") as of the Closing Date and contains provisions similar
to the provisions of the WELCO Savings Program to the extent required by Section
411(d)(6) of the Code for account balances to be transferred from the CBS
Savings Program. Each Business Employee eligible to participate in the WELCO
Savings Program as of the Closing Date shall become eligible to participate in
Purchaser's 401(k) Plan as of the Closing Date. Business Employees shall receive
credit for all service with Sellers and their Affiliates for purposes of
eligibility and vesting under Purchaser's 401(k) Plan to the extent credited
under the WELCO Savings Program. Effective as of the date of transfer described
in (iii) below, CBS shall fully vest the account balances of Business Employees
under the WELCO Savings Program and make all applicable contributions under the
WELCO Savings Program otherwise provided for in the plan year in which the
Closing occurs with respect to compensation earned by Business Employees prior
to the Closing Date, without regard to any provision of the WELCO Savings
Program requiring a minimum number of hours of service, or employment on any
particular date, if the applicable Business Employees would have qualified for a
contribution if they had remained employed with Sellers.

                  (ii) As soon as reasonably practicable after the Closing Date,
         Purchaser shall provide CBS with (A) either a copy of a favorable IRS
         determination letter to the effect that Purchaser's 401(k) Plan is
         qualified under Section 401(a) of the Code or an opinion of Purchaser's
         counsel, reasonably satisfactory to CBS, to such effect and (B) an
         opinion of Purchaser's counsel, reasonably satisfactory to CBS, that
         the Purchaser's 401(k) Plan will satisfy Section 411(d)(6) of the Code
         with respect to account balances to be transferred to the Purchaser's
         401(k) Plan from the WELCO Savings Program pursuant to (iii) below.

                  (iii) As soon as reasonably practicable after the Closing Date
         and receipt of the documentation described in (ii) above, CBS shall
         cause to be transferred from the WELCO Savings Program to Purchaser's
         401(k) Plan assets having a fair market value equal to the aggregate
         value of the account balances in the WELCO Savings Program as of the
         date of transfer (such transfer to be in (x) shares of common stock of
         Seller to the extent of shares in the CBS Common Stock Fund applicable
         to Business Employees, (y) in notes evidencing loans to Business
         Employees from their account balances, (z) in cash, (xx) to the extent
         of the account balances of the Business Employees in the CBS Savings
         Program allocable to the Fixed Income Fund, in investment instruments
         which approximate from a quality and interest rate perspective assets
         held by the fund, but subject to the applicable fiduciary requirements
         of the Purchaser's 401(k) Plan relating to quality and interest rate
         considerations), (yy) all qualified domestic relations orders



                                       66
<PAGE>   78

         (within the meaning of Section 414(p) of the Code) with respect to
         Business Employees and (zz) such other assets as Purchaser and CBS
         mutually agree upon and Purchaser shall cause the Purchaser's 401(k)
         Plan to accept the receipt of such transfers and the liabilities
         relating thereto.

                  (iv) Sellers represent, warrant and covenant that after the
         Closing and at the time of the transfer of assets to the Purchaser's
         401(k) Plan, the WELCO Savings Program will be qualified under Section
         401(a) and (k) of the Code and, to the extent pertinent to the
         qualified status of the Purchaser's 401(k) Plan as relevant to asset
         transfers as provided herein, for all prior periods, and will not be
         disqualified retroactively to any such time or for any such period.
         Sellers and Purchaser shall cooperate in making, and shall make, all
         appropriate filings required under the Code and ERISA, and the
         regulations thereunder, and shall further cooperate to ensure that the
         transfers described in this Section 5.5(d) satisfy the applicable
         requirements of Sections 401(k), 414(l), 411(d)(6) and 401(a)(12) of
         the Code and the regulations thereunder.

                  (v) Purchaser's 401(k) Plan shall maintain a CBS common stock
         fund, in accordance with applicable law, for Business Employees who so
         elect, for such period as Purchaser determines is necessary for an
         orderly transition. No new investments in CBS common stock shall be
         required to be permitted after the Closing Date.

                  (e) UNION REPRESENTATION. Purchaser agrees with respect to any
collective bargaining agreement that relates to Business Employees, to (i)
recognize each union with an agreement listed in Schedule 4.1(j) which at the
Closing Date represents any group of Business Employees as the collective
bargaining representatives of such employees as of the Closing Date, (ii)
provide such employees with comparable wages and benefits as those in effect on
the date of this Agreement in accordance with such collective bargaining
agreements, and (iii) assume the obligations for Business Employees and Former
Employees under any such collective bargaining agreement that by its terms
requires such assumption.

                  (f) MEDICAL AND DISABILITY BENEFITS; LIFE INSURANCE. (i)
Effective as of the Closing Date, Purchaser shall establish employee welfare
benefit plans, including but not limited to medical and dental, disability,
group life, travel and accident, and accidental death and dismemberment
insurance plans, which (x) provide continuous coverage to Business Employees and
their eligible spouses and dependents, (y) credit service with Sellers or their
Affiliates for purposes of eligibility and benefit levels, and (z) for medical
and dental benefits, waive any pre-existing condition limitations and credit the
amount of any co-payments and deductibles incurred during the calendar year of
the Closing.

                  (ii) Effective as of the Closing Date, Purchaser shall be
         responsible for all



                                       67
<PAGE>   79

         employee welfare benefit plan claims (whether for insurance, benefits
         or otherwise) with respect to Business Employees and Inactive Employees
         and their eligible spouses and dependents, whether incurred prior to or
         after the Closing Date. Sellers shall cooperate with Purchaser in
         transferring to Purchaser applicable insurance company reserves
         associated with claims covering Business Employees and Inactive
         Employees currently receiving benefits from the Westinghouse Long Term
         Disability Plan or Management Disability Benefit Plans. Sellers shall
         pay or cause to be paid medical, dental and other welfare benefit
         claims incurred but not paid in the ordinary course, prior to the
         Closing Date with respect to Business Employees and Inactive Employees
         and Purchaser shall reimburse and indemnify the Sellers for the amount
         of such Payments.

                  (iii) As of the Closing Date Purchaser shall adopt a plan or
         plans providing retiree medical and other retiree welfare benefits for
         Business Employees and Former Employees and their eligible spouses and
         dependents (such plans and their successors the "Purchaser FAS 106
         Plans") that is substantially similar to such plan or plans maintained
         by CBS or its Affiliates in the U.S. immediately prior to the Closing
         Date for its Business Employees and Former Employees, their eligible
         spouses and dependents (the "WELCO FAS 106 Plans") so that during the
         Benefits Maintenance Period the combination of the Purchaser FAS 106
         Plans and the WELCO FAS 106 Plans (as modified as described in clause
         (iv) below) provide the same benefit and the same cost sharing (with
         retirees) as if such Business Employees and Former Employees continued
         under the WELCO FAS 106 Plans as in effect on the Closing Date without
         change. The Purchaser FAS 106 Plans will provide that the benefits
         payable under such plans will be offset by the benefits provided under
         the WELCO FAS 106 Plans, as to be amended as described in subsection
         (iv) below. During the Benefits Maintenance Period, Purchaser shall
         continue without adverse change the Purchaser FAS 106 Plans.

                  (iv) CBS shall establish a new plan to provide FAS 106
         coverage or amend the WELCO FAS 106 Plans effective as of the Closing
         Date to provide that CBS obligations under such plans with respect to
         Business Employees and Former Employees of each of the Residual
         Divisions shall be limited in each calendar year, commencing with the
         Closing Date, to the Non-Governmental Allocation Percentage of the
         amounts set forth in Schedule 5.5(f)(iv) of the Disclosure Schedule
         applicable to each Residual Division (the "OPEB Schedule"), as
         described below (e.g., if the Non-Governmental Allocation Percentage is
         30% and the OPEB Schedule payment for a given year is $100,000, the
         payment obligation for such year under the WELCO FAS 106 Plan is
         $30,000). The OPEB Schedule shall be updated by CBS after the Closing
         Date to reflect Business Employees and Former Employees of the Residual
         Divisions (the "OPEB Employees") as of the Closing Date. CBS may amend
         the WELCO FAS 106 Plans after the Benefits Maintenance Period to
         conform to the provisions of the



                                       68
<PAGE>   80

         Purchaser FAS 106 Plans as applicable to the Residual Divisions after
         the Benefits Maintenance Period. Such payment obligations shall be
         cumulative so that if a scheduled payment is not made in full in any
         year because the aggregate benefit payment required is less than the
         scheduled payment, the balance not paid out shall be carried forward to
         the next year. Such payments represent the accrued obligations of CBS
         as calculated under FAS 106, for post-retirement benefit obligations
         other than pensions as of the Closing Date with respect to OPEB
         Employees, their eligible spouses and dependents under the WELCO FAS
         106 Plans (the "FAS 106 Obligation"). Such payments under the WELCO FAS
         106 Plans, as adjusted as described below, shall be the only obligation
         of CBS to Business Employees, their eligible spouses and dependents (or
         to the Purchaser) with respect to post-retirement welfare benefits.
         Purchaser shall indemnify CBS for any liability to Business Employees
         and Former Employees, their eligible spouses and dependents for all
         post-retirement welfare benefits (including retiree medical and retiree
         life, other than amounts paid by CBS or Sold Subsidiaries prior to the
         Closing Date) other than obligations of CBS under the WELCO FAS 106
         Plans as described in this subsection (iv) and subsection (v). The
         payment obligations of CBS under the OPEB Schedule shall be actuarially
         adjusted downwards in the event of an "actuarial gain" (as defined
         below) arising from any of the following events (a "FAS 106 Event")
         (whether applicable to some or all of the Business Employees): (A) a
         change in the benefit design (including but not limited to any
         reduction of benefit levels or reduction or freezing of the employer
         portion of benefit costs) or plan termination by the Purchaser of the
         Purchaser FAS 106 Plans applicable to OPEB Employees, their eligible
         spouses and dependents (e.g. in the event of a termination of the
         Purchaser FAS 106 Plans, the OPEB Schedule shall be reduced to zero
         (0)), (B) an increase in the contribution rate paid (other than an
         increase proportionate to an increase in overall plan costs or an
         increase provided by plan provisions) by OPEB Employees, their eligible
         spouses and dependents instituted by the Purchaser under the Purchaser
         FAS 106 Plans, (C) the enactment of legislation which reduces or
         eliminates the requirement of the Purchaser to provide retiree benefits
         under the Purchaser FAS 106 Plans, (D) a Disposition, (E) a closing of
         a plant or plants by Purchaser (other than terminations announced by
         CBS prior to the Closing Date), or (F) a WARN Event. Such adjustment
         shall be made as of the January 1 following the calendar year in which
         the FAS 106 Event occurs. Actuarial gain, for purposes of this Section
         5.5(f)(iv), shall be determined by the CBS Actuary as of the Closing
         Date, for the purpose of calculating the FAS 106 Obligation. Such gain
         shall be determined with respect to the WELCO FAS 106 Plans as if the
         FAS 106 Event applied to the WELCO FAS 106 Plans to the same extent and
         as of the same date they apply to the Purchaser FAS 106 Plans and shall
         be measured by the difference between the OPEB Schedule (or as
         subsequently modified pursuant to this Section 5.5(f)(iv)) (the
         "Existing Schedule") and the OPEB Schedule that would have been
         determined as of the Closing Date to reflect the FAS 106 liability, if
         the FAS 106




                                       69
<PAGE>   81

         Event were known as of the Closing Date (the "Revised Schedule"). To
         determine whether the change from the Existing Schedule to the Revised
         Schedule would result in an actuarial gain, the scheduled payments
         under each schedule (whether resulting in a gain or a loss) shall be
         discounted back to the first day of the calendar year in which the FAS
         106 Event occurred, utilizing the discount rate utilized by CBS as of
         December 31, 1997 to determine its APBO for FAS 106 purposes (the
         "Discount Rate"). In no event shall any actuarial losses in connection
         with the Purchaser FAS 106 Plans (other than arising as a result of a
         FAS 106 Event which results in a net actuarial gain) offset any
         actuarial gains as calculated under this Section 5.5(g)(iv). If the
         result of discounting the scheduled payments would result in the
         Revised Schedule having a lower present value obligation than the
         Existing Schedule, the Revised Schedule shall be substituted for the
         Existing Schedule as the OPEB Schedule. In no event shall the OPEB
         Schedule ever be increased, except (a) in the event of a final
         determination of the Non-Governmental Allocation Percentage applicable
         to a Residual Division or (b) to the extent required by a final
         non-appealable court order or as otherwise agreed to by the parties,
         but in any event under (b) the OPEB Schedule shall not be increased
         above the amount as in effect immediately prior to the change which
         triggered the reduction in question. Any payment made by CBS hereunder
         that exceeds a payment obligation for any year based on a Revised
         Schedule, shall be utilized to reduce a future payment obligation under
         the Revised Schedule. Upon a final determination of Non-Governmental
         Allocation Percentage applicable to a Residual Division, the OPEB
         Schedule applicable to such Residual Division shall be adjusted upwards
         or downwards utilizing the same methodology used to calculate changes
         for a FAS 106 Event.

                  (v) The Purchaser and CBS shall cooperate with each other so
         that, to the maximum extent practicable, benefits shall be paid and
         administered under the CBS FAS 106 Plans and the Purchaser FAS 106
         Plans as applicable to OPEB Employees, through the third-party service
         provider to be selected by Purchaser, subject to consent of CBS, not to
         be unreasonably withheld. Any expenses allocable to CBS under such
         arrangement shall reduce CBS's payment obligation under the CBS FAS 106
         Plans as reflected by the OPEB Schedule on a dollar-for-dollar basis.
         Purchaser shall notify CBS within thirty days after any FAS 106 Event
         and shall cooperate with CBS in providing data to determine any
         adjustments in the OPEB Schedule.

                  (vi) Subject to the requirements of applicable law, CBS shall
         use all reasonable efforts to cash out Business Employees and Former
         Employees from a trust qualified under Section 501(c)(9) of the Code
         maintained by CBS (the Retiree Health Care Security Fund). To the
         extent such trust does not make such distributions prior to the Closing
         Date, CBS shall cause the transfer to a trust established by Purchaser
         satisfying the requirements of Section 501(c)(9) of the Code of the
         funds in such trust



                                       70
<PAGE>   82

         allocable to such Business Employees and Former Employees. The trust to
         be established by Purchaser shall have terms substantially similar to
         the terms of the CBS Trust.

                  (g) SEVERANCE OBLIGATIONS. CBS and Purchaser agree that the
transactions contemplated hereby shall not constitute a severance of employment
of any Business Employee prior to the consummation of the transactions
contemplated hereby, and that such employees will be deemed for all purposes to
have continuous and uninterrupted employment before and immediately after the
Closing. Except as required by Law or an applicable collective bargaining
agreement or as otherwise agreed in writing by CBS and Purchaser, Purchaser
shall provide severance and other separation benefits to each Business Employee
terminated by Purchaser during the Benefits Maintenance Period upon terms and
conditions that are comparable to the severance and other separation benefits
provided under the Involuntary Separation Program, the Employee Security and
Protection Plan and any applicable Free Standing Plan, which arrangements shall
credit service with the Sellers and its Affiliates prior to the Closing Date for
purposes of determining the amount of such severance and other separation
benefits. Purchaser shall indemnify and hold Sellers and their Affiliates
harmless from and be responsible for any claims made by any Business Employee or
Former Employee for severance or other benefits based on separation, for any
claims based on breach of contract and for any other claims arising out of or in
connection with the employment or the failure to offer employment to, or the
termination of employment of, any Business Employee or Former Employee, other
than claims arising as a direct result of the transactions contemplated hereby.
CBS shall be responsible and indemnify Purchaser for any claims made by any
Business Employee or Former Employee for severance or other benefits based on
separation (other than severance benefits based on separation arising from acts
of Purchaser on or after the Closing Date), for any claims based on breach of
contract and for any other claims, in each case arising as a direct result of
the transactions contemplated hereby; provided, however, that CBS shall not be
responsible (and Purchaser shall be responsible) for any such claim if the
principal basis of such claim is due to Purchaser's breach of any provision of
this Section 5.5.

                  (h) EXECUTIVE COMPENSATION. Purchaser shall assume all
Liabilities and obligations of CBS and its Affiliates relating to Business
Employees and Former Employees under the Westinghouse Executive Pension Plan
(including, without limitation, Savannah River, notwithstanding that there is no
specific government reimbursement for such expenses), except to the extent the
Novation Agreements provide that such obligations (other than attributable to
the Non-Governmental Allocation Percentage or to Savannah River) will not be
reimbursed to the same extent reimbursed prior to the Novation Agreements.

                  (i) RETIREE WELFARE BENEFITS. Purchaser shall assume all
Liabilities and Obligations of CBS and its Affiliates relating to Business
Employees and Former Employees under the CBS FAS 106 Plans covering the
Business, except as set forth in Section 5.5(f) and



                                       71
<PAGE>   83

except to the extent the Novation Agreements provide that such obligations
(other than the FAS 106 Obligation) will not be reimbursed to the same extent
reimbursed prior to the Novation Agreements.

                  (j) RETAINED LIABILITIES. CBS shall retain liability and
responsibility for all benefits payable under (x) the WELCO Pension Plan except
to the extent liabilities are transferred with respect to Business Employees and
Former Employees to the Individual Spun-Off Plans and Residual Spun-Off Plan,
(y) the WELCO Executive Pension Plan except to the extent liabilities are
assumed under Section 5.5(h), (z) the WELCO FAS 106 Plans except to the extent
liabilities are assumed under Section 5.5(i), (xx) the WELCO Savings Program
(other than assets and liabilities to be transferred to the Purchaser's 401(k)
Plan under Section 5.5(d)), (yy) the CBS Long-Term Incentive Plan, (zz) deferred
compensation obligations under the Westinghouse Annual Incentive Plan and any
other employee deferral arrangements, except to the extent attributable to Free
Standing Plans, and (xxx) retention bonuses for executives relating to this
transaction (but not severance obligations arising from acts of Purchaser).

                  (k) COOPERATION. The parties agree to furnish each other with
such information concerning employees and employee benefit plans, and to take
all such other action, as is necessary and appropriate to effect the
transactions contemplated by this Agreement.

                  (l) WARN ACT. Purchaser agrees to provide any required notice
under the WARN Act and any similar statute, and otherwise to comply with any
such statute with respect to any "plant closing" or "mass layoff" (as defined in
the WARN Act) or similar event affecting Business Employees and occurring on or
after the Closing. CBS agrees to provide any notice required under such statute
prior to or arising as a result of the Closing.

                  (m) WORKERS COMPENSATION. CBS or its Affiliates currently
sponsors a program that provides workers compensation benefits for eligible
Business Employees and Former Employees ("CBS's Workers Compensation Program").
Effective as of the Closing Date, Purchaser shall take all necessary and
appropriate action to adopt a workers compensation program providing such
workers compensation benefits for the Business Employees and Former Employees
covered by such program ("Purchaser's Workers Compensation Program").
Purchaser's Worker Compensation Program shall be responsible for all claims for
workers compensation benefits which are incurred prior to, on or following the
Closing Date by Business Employees and Former Employees, including claims that
are otherwise payable under the terms and conditions of CBS's Workers
Compensation Program.

                  (n) FREE-STANDING PLANS. Notwithstanding the foregoing
provisions of this Section 5.5, effective as of the Closing, Purchaser shall
assume and be responsible for all liabilities and obligations under the
Free-Standing Plans, except as set forth below in this



                                       72
<PAGE>   84

Section 5.5(n).

                  Prior to the assumption of the Individual Spun-Off Plans, CBS
or its Affiliates shall make such payments to the plans as are required pursuant
to Section 4 of the Contractual Modification, the amount of which has been
determined by the applicable government agency after audit. In addition, the
Sellers will contribute to the Individual Spun-Off Plans pursuant to the
Contractual Modifications amounts equal to the "transitional asset" attributable
to prior government reimbursements that the Sellers or the Sold Subsidiaries are
determined to hold (to be determined upon audit by the applicable government
agency pursuant to Contractual Modifications) with respect to the Westinghouse
Executive Pension Plan as applicable to Business Employees and Former Employees
of the Business covered by the Contractual Modification.

                  CBS shall request an audit of the Residual Spun-Off Plan by
the applicable government agencies. Any assumption of such plan by Purchaser
shall be subject to a certification by such government agency that the assets
and liabilities of the plan conform with government cost accounting standards.
CBS will make up any shortfalls determined by such audit. CBS and Purchaser
shall take all action necessary and appropriate (including, in the case of
Purchaser, establishing legal entities to serve as plan sponsor) to establish
Purchaser as successor to CBS or its Affiliates to all rights, assets, duties,
liabilities and obligations under or with respect to the Free-Standing Plans and
will use all reasonable efforts to obtain with respect to the Residual Spun-Off
Plan, an agreement similar to the Contract Modifications. CBS shall contribute
or cause a Sold Subsidiary to contribute to the Residual Spun-Off Plan, prior to
assumption by Purchaser, an amount equal to the Non-Governmental Allocation
Percentage applicable to each Residual Division of the unfunded accrued benefit
obligation (calculated using the FASB 87 assumptions utilized by CBS as of
December 31, 1997) of that portion of the Residual Spun-Off Plan and the
Westinghouse Executive Pension Plan (other than with respect to Savannah River)
allocable to each Residual Division, calculated as of the Closing Date (the
"True-Up Payment").

                  Subject to the agreement of Purchaser, not to be unreasonably
withheld, Seller may transfer to Purchaser a Free-Standing Plan prior to any
audit referred to above. In such event, the Purchaser and CBS will make
equitable adjustments among themselves to adjust for any changes required by
such audits, with interest to be added to such adjustments at the "LIBOR" rate
at the time of payment.

                  In the event the Non-Governmental Allocation Percentage
applicable to any Residual Division is changed based on a final determination by
the applicable governmental agency, the Purchaser or CBS, as the case may be,
shall make a payment to the other within ninety (90) days of such final
determination, of the difference between the True-Up Payment and the amount the
True-Up Payment would have been if the final percentage were known at



                                       73
<PAGE>   85

the time of the True-Up Payment (the "Differential"). The paying party shall pay
interest on the Differential from the date of the True-Up Payment to the date of
payment of the Differential at the "LIBOR" rate at the time of payment of the
Differential.

                  (o) ACTUARIAL DETERMINATIONS AND PAYMENTS. (i) The
calculations of actuarial gains under subsection (f)(iv) shall be performed by
the CBS Actuary as soon as practicable after CBS receives notice from Purchaser
or CBS otherwise becomes aware of a FAS 106 Event. Purchaser shall provide CBS
with sufficient data to enable the determination of any actuarial losses and/or
actuarial gains within the 30 days following a FAS 106 Event.

                  (ii) No later than 60 days after the receipt by CBS of both
         the notice from Purchaser that a FAS 106 Event has occurred and
         sufficient data to make a determination has been delivered, CBS will
         deliver to Purchaser the results of the determination of the actuarial
         gain ( a "Determination"), and all reasonably necessary supporting
         information in order to permit Purchaser's actuary to verify the
         accuracy of the Determination. Each Determination will be conclusive
         and binding on the parties unless Purchaser, within the 30-day period
         after the delivery of such results and supporting information, notifies
         CBS in writing that it disputes the accuracy of the calculation,
         specifying the nature of the dispute and the basis therefor (the
         "Notice").

                  (iii) Actuaries retained by CBS and Purchaser shall attempt in
         good faith to reach agreement to resolve all of the disputes set forth
         in the Notice within 30 days after the Notice is given by Purchaser to
         CBS. If actuaries retained by CBS and Purchaser cannot resolve all
         disputes with respect to a Determination within such 30-day period, CBS
         and Purchaser shall jointly select a third, impartial actuary from a
         nationally recognized actuarial firm to resolve the dispute (the same
         such actuary shall resolve all concurrent Determinations). If the
         parties cannot jointly select a third, impartial actuary within 15 days
         after the end of such 30-day period, the President of the Conference of
         Consulting Actuaries shall select an impartial actuary. The cost of the
         impartial actuary shall be shared equally by CBS and Purchaser.

                  (iv) Promptly, but no later than 60 days after his or her
         selection, an impartial actuary selected under (iii) above shall review
         the results of the Determination calculation, the supporting
         information with respect to the Determination and the Notice, and shall
         reach his or her own decision as to the issues in dispute and the
         determination of the actuarial gain or actuarial loss, as the case may
         be (which determination shall be equal to or between the respective
         amounts asserted by CBS and Purchaser). Such determination shall be
         final and conclusive for all purposes.

                  (v) Within 30 days after a final determination of any
         actuarial gain under Section 5.5(f)(iv) CBS shall substitute a Revised
         Schedule in place of the Existing Schedule.




                                       74
<PAGE>   86

                  (p) NO RIGHT TO EMPLOYMENT. Nothing herein expressed or
implied shall confer upon any of the employees of CBS or Purchaser, or any of
their respective Affiliates, any additional rights or remedies, including,
without limitation, any additional right to employment, or continued employment,
for any specified period, of any nature or kind whatsoever under or by reason of
this Agreement.

                  (q) POST-CLOSING HIRING OF EMPLOYEES. If within the period
ending one (1) year after the Closing Date, Purchaser or any of its Affiliates
hires any employee of STC (other than Business Employees), Purchaser shall
reimburse CBS for any severance and other related termination costs paid by CBS
or its Subsidiaries to or on account of such employment with CBS or any of its
Subsidiaries during such one (1) year period.

                  (r) ALTERNATIVE PROCEDURE. CBS and Sellers and Purchaser agree
that, pursuant to the "Alternative Procedure" provided in section 5 of Revenue
Procedure 96-60, 1996-2 C.B. 399, (i) Purchaser will report on a
predecessor/successor basis as set forth therein, (ii) CBS and its Affiliates
will be relieved from filing a Form W-2 with respect to any Business Employee
who accepts employment with Purchaser or its Affiliates, and (iii) Purchaser
will undertake to file (or cause to be filed) a Form W-2 for each such employee
for the year that includes the Closing Date, including the portion of such year
that such employee was employed by CBS or its Affiliates (provided, however,
that any agreement between CBS and Purchaser that CBS or its Affiliates shall
furnish to Purchaser payroll and related services under the Transitional
Services Agreement provided for in Section 5.20(a) and any actions by either
party in connection with such agreement shall not alter or otherwise affect the
agreement set forth in this Section 5.5(r)). CBS agrees to provide Purchaser
with all payroll and employment-related information with respect to each
Business Employee who accepts employment with Purchaser (or an Affiliate) and to
otherwise cooperate in following the "Alternative Procedure."

                  (s) COBRA. Effective as of Closing Date, Purchaser shall
assume all responsibility for COBRA notices and coverage for Business Employees
and Former Employees (and their eligible dependents).

                  SECTION 5.6. COLLECTION OF RECEIVABLES. From and after the
Closing, Purchaser shall have the right and authority to collect for its own
account all Accounts Receivable and other items that are included in the
Acquired Assets and to endorse with the name of any of Sellers, any checks or
drafts received with respect to any such Accounts Receivable or other items and
CBS agrees promptly to deliver or cause to be delivered to Purchaser any cash or
other property received directly or indirectly by any of Sellers with respect to
such receivables and other items, including any amounts payable as interest.



                                       75
<PAGE>   87

Notwithstanding any provisions of the Novation Agreements to the contrary,
Purchaser agrees that CBS is entitled (i) to all cost improvement payments with
respect to the Government Contracts received prior to the Closing Date and (ii)
if the Closing occurs prior to November 30, 1998, to fifty percent (50%) of all
cost improvement payments with respect to the Government Contracts received
between the Closing Date and November 30, 1998, provided that, in the case of
clause (ii) such payments relate to the U.S. government fiscal year ending
September 30, 1998, and Purchaser agrees to remit such portion of any funds
received during such period to CBS within 10 days of receipt.

                  SECTION 5.7. EXPENSES. Whether or not the Closing takes place,
and except as otherwise specifically provided in this Agreement (including with
respect to Transfer Taxes), all costs and expenses incurred in connection with
this Agreement and the transactions contemplated hereby shall be paid by the
party incurring such costs or expenses.

                  SECTION 5.8. BROKERS OR FINDERS. Each of Purchaser and CBS
represents, as to itself and its Affiliates, that no agent, broker, investment
banker or other Person is or will be entitled to any broker's or finder's fee or
any other commission or similar fee in connection with any of the transactions
contemplated by this Agreement, except, as to Purchaser and its Affiliates,
Batchelder & Partners, Inc. and Rothschild, Inc. whose fees and expenses will be
paid by Purchaser, and each of Purchaser and CBS respectively agrees to
indemnify and hold the other harmless from and against any and all claims,
liabilities or obligations with respect to any other fees, commissions or
expenses asserted by any Person on the basis of any act or statement alleged to
have been made by such party or its affiliate.

                  SECTION 5.9. SHARED TECHNOLOGY AND TRADEMARK LICENSE
AGREEMENTS.

         (a) On the Closing Date, CBS and Purchaser shall enter into a Shared
Technology Agreement in the form of Exhibit A hereto (the "Shared Technology
Agreement"), wherein, to the extent CBS and Purchaser have rights on the Closing
Date:

                  (i) Purchaser shall grant to CBS a world-wide, royalty-free,
         nonexclusive, perpetual license to use Intellectual Property and
         Technology to satisfy its existing obligations, and support its current
         businesses that do not compete with the Business;

                  (ii) CBS shall grant to Purchaser a nonexclusive, world-wide,
         royalty-free, perpetual license to use intellectual property and
         technology retained by CBS, that are pertinent to the Business; and

                  (iii) It shall be agreed that each licensed party shall have
         appropriate access to the corresponding technology reasonably required
         for the licensed purpose. Such right of access to technology shall be
         appurtenant to the license and assignable to the



                                       76
<PAGE>   88

         same extent as the license. The owner of the Business, upon Closing,
         shall have access to all such technology, that is primarily applicable
         to a Nuclear Installation, in the possession of the Business and, at
         the sole discretion of the owner of the Energy Systems Business, have
         such technology delivered to it.

                  (b) On the Closing Date, CBS and Purchaser shall enter into a
Trademark and Trade Name License Agreement in the form of Exhibit B hereto,
granting certain licenses to Purchaser and its Affiliates to use the names and
marks "WESTINGHOUSE", "CIRCLE W" and "You can be sure ... if it's Westinghouse."

                  (c) The parties acknowledge and agree that, as between the
Energy Systems Business and the GESCO Businesses, the Energy Systems Business is
the owner of all CBS intellectual property and technology, including
Intellectual Property and Technology, that is primarily applicable to a Nuclear
Installation.

                  SECTION 5.10. CERTAIN INFORMATION. (a) After the Closing, upon
reasonable written notice, Purchaser and CBS shall furnish or cause to be
furnished to each other and their respective accountants, counsel and other
representatives access, during normal business hours, to such information
(including records pertinent to the Business), personnel and assistance relating
to the GESCO Businesses as is reasonably necessary for financial reporting and
accounting matters, the preparation and filing of any returns, reports or forms
or the defense of, prosecution of, or response required under, or pursuant to,
any lawsuit, action or proceeding (including any proceeding involving CBS and
any Excluded Assets, any Excluded Liabilities, any environmental matters related
to the Acquired Assets and the matters referred to in Section 2.3(b)(xiii)) or
in order to enable the parties to comply or monitor compliance (including with
respect to Purchaser's obligations in respect of the Assumed Liabilities) with
their respective obligations under this Agreement. Purchaser and CBS shall also
furnish or cause to be furnished to each other and their respective accountants,
counsel and other representative's access, during normal business hours, to such
information for any other reasonable business purpose. Purchaser and CBS shall,
and shall cause their Affiliates to, retain until five years after the Closing
Date all such records pertinent to the Business which are owned by such Person
immediately after the Closing (excluding any Excluded Assets); after the end of
such period, before disposing of any such records, the applicable party shall
give notice to such effect to the other, and shall give the other, at the
other's cost and expense, a reasonable opportunity to remove and retain all or
any part of such records as the other may select. Cooperation with respect to
Tax matters shall be governed by Section 5.14(j). Cooperation with respect to
Intellectual Property and Technology matters shall be governed by Section
5.10(b).

                  (b) After the Closing, upon reasonable written notice, CBS
will deliver at Purchaser's expense all reasonably available records regarding
the conception, reduction to



                                       77
<PAGE>   89

practice, evaluation, and efforts to patent or otherwise protect Intellectual
Property or Technology. CBS will at all reasonable times cooperate with
Purchaser's reasonable efforts to protect any of the Intellectual Property or
Technology by supplying (i) all requested information reasonably available to
CBS about any public use or offer to sell an invention that occurred prior to
the filing of a U.S. application on the invention, (ii) all requested
information reasonably available to CBS about any use of a trademark or service
mark, or (iii) all requested information reasonably available to CBS about any
software or copyrighted work. With respect to inventions created by inventors
who remain in the employ of CBS after the Closing, CBS promises to provide its
full cooperation with any efforts by Purchaser to patent said inventions or
enforce patents on said inventions, including instructing the employee promptly
to review any draft patent application submitted by Purchaser and advise
Purchaser as to the revisions necessary to make it a full and accurate
disclosure of the invention and to execute all truthful and lawful oaths of
inventorship or assignment deeds presented by Purchaser for purposes of
patenting or protecting the invention. With respect to inventions created by
inventors who are past employees of CBS or any of its Subsidiaries, CBS will, on
request by Purchaser, use its commercially reasonable efforts to encourage the
past employee to give Purchaser full cooperation in connection with efforts to
patent said invention or enforce a patent on said invention. After a period of
two years following the Closing Date, CBS or any of its Subsidiaries that render
services under this Section 5.10(b) shall be entitled to reasonable
reimbursement from Purchaser for its time, as well as out-of-pocket expenses as
provided for above, for such services rendered after the two-year period.

                  SECTION 5.11. BULK TRANSFER LAWS. Purchaser hereby waives
compliance by Sellers with the provisions of any so-called "bulk transfer law"
of any jurisdiction in connection with the sale of the Acquired Assets to
Purchaser.

                  SECTION 5.12. ADDITIONAL AGREEMENTS. Subject to the provisions
of Section 5.4, each of Purchaser and CBS will use all reasonable efforts to
facilitate and effect the implementation of the transfer of the Acquired Assets
to Purchaser and the assumption of the Assumed Liabilities by Purchaser and, for
such purpose but without limitation, each of Purchaser and CBS promptly will at
and after the Closing execute and deliver or cause to be executed and delivered
to the other party such assignments, deeds, bills of sale, assumption
agreements, consents and other instruments of transfer or assumption as
Purchaser or its counsel or CBS or its counsel may reasonably request as
necessary or desirable for such purpose (it being understood that any such
assignment, deed, bill of sale, assumption agreement, consent or other
instrument of transfer or assumption shall not provide for any representations
or warranties or any obligations or liabilities that are not otherwise expressly
provided for in this Agreement). At any time and from time to time after the
Closing Date at the request of Purchaser, and without further consideration, CBS
will, and will cause the other Sellers to, execute and deliver such other
instruments of sale, transfer, conveyance, assignment and confirmation and take
such other action as Purchaser may reasonably deem



                                       78
<PAGE>   90

necessary or desirable in order to transfer, convey and assign more effectively
to Purchaser, the Acquired Assets, to put Purchaser in actual possession and
operating control of the Business and to assist Purchaser in exercising all
rights with respect thereto. Purchaser will cooperate with CBS with respect to
the matters set forth in Item (xi) of Schedule 5.1(a), as provided therein.

                  SECTION 5.13. CERTAIN UNDERSTANDINGS. Purchaser acknowledges
that none of Sellers or any other Person has made any representation or
warranty, express or implied, as to the accuracy or completeness of any
information regarding the Business, the Acquired Assets or other matters not
included in this Agreement or the Schedules hereto (including, without
limitation, the information, estimates, forecasts and projections contained in
the Memorandum), and none of Sellers or any other Person will be subject to any
liability to Purchaser or any other Person resulting from the distribution to
Purchaser, or Purchaser's use of, any such information, including any
information, documents or material made available to Purchaser in certain "data
rooms" or in any other form in expectation of the transactions contemplated
hereby. Purchaser acknowledges that, should the Closing occur, Purchaser will
acquire the Acquired Assets without any representation or warranty as to
merchantability or fitness for any particular purpose, in an "as is" condition
and on a "where is" basis, except as otherwise expressly represented or
warranted herein.

                  SECTION 5.14. ALLOCATION; TAX MATTERS.

                  (a) CBS and Purchaser agree to use their best efforts to enter
into an agreement (the "Allocation Agreement") as soon as practicable (but in
any event no later than 150 days after the Closing Date) to allocate the
Purchase Price, the Assumed Liabilities, and all other capitalizable costs among
(i) the Acquired Assets and (ii) the assets held by each Sold Subsidiary for all
applicable Tax purposes, including Code Section 1060. Purchaser shall initially
prepare a statement setting forth a proposed computation and allocation of the
aggregate purchase price (the "Computation") and submit it to CBS no later than
60 days after the Closing Date. If, within 30 days of CBS's receipt of the
Computation, CBS shall not have objected in writing to such Computation, the
Computation shall become the Allocation Agreement. If 60 days after CBS's
receipt of the Computation, CBS and Purchaser have not adopted an Allocation
Agreement, any disputed aspects of the Allocation Agreement shall be resolved
within 90 days of CBS's receipt of the Computation, by a law or accounting firm
mutually acceptable to CBS and Purchaser (the "Neutral Auditors"), which shall
resolve such dispute pursuant to, first, the terms of this Agreement and,
second, the application of applicable Tax Laws to the relevant facts. The
decision of the Neutral Auditors shall be final, and the costs, expenses and
fees of the Neutral Auditors shall be borne equally by CBS and Purchaser. CBS
and Purchaser shall report the Tax consequences of the transactions contemplated
by this Agreement consistent with the terms of this Agreement and the Allocation
Agreement.



                                       79
<PAGE>   91

                  (b) After the Closing, from time to time, Purchaser and CBS
shall agree upon revisions to the Allocation Agreement to reflect any
adjustments to the consideration. Purchaser and CBS shall report the Tax
consequences of the transactions contemplated by this Agreement in a manner
consistent with the terms of this Agreement and the Allocation Agreement, as it
may be revised from time to time. Any disputes regarding such revisions shall be
resolved by the Neutral Auditors.

                  (c) Purchaser and CBS shall file and cause to be filed all Tax
Returns and execute such other documents as may be required by any taxing
authority, in a manner consistent with the Allocation Agreement, as it may be
revised from time to time. CBS shall prepare Internal Revenue Service Form 8594
pursuant to Section 1060 of the Code relating to the transactions contemplated
by this Agreement based on the Allocation Agreement, as it may be revised from
time to time, and deliver such form to Purchaser. Purchaser and CBS shall file,
or cause the filing of, such form with each relevant taxing authority. Any
disputes under this provision shall be resolved by the Neutral Auditors.

                  (d) Irrespective of Article 8 or any other provision hereof,
Sellers and Purchaser shall each bear and be liable for 50% of the transfer,
documentary, sales, use, registration, stamp, value-added and other similar
taxes (including all applicable real estate transfer taxes and real property
gains taxes), including any penalties, interest and additions to tax, incurred
in connection with the transactions contemplated hereby ("Transfer Taxes").
Sellers or Purchaser, as the case may be, shall pay the Transfer Taxes for which
it is liable under applicable Law. Five days before any such payment of Taxes is
due, the nonpaying party shall reimburse the paying party for 50% of such Taxes.
CBS and Purchaser shall cooperate in timely making and filing all Tax Returns as
may be required to comply with the provisions of any Transfer Tax Laws. To the
extent legally able to do so, Purchaser shall deliver to CBS exemption
certificates satisfactory in form and substance to CBS with respect to Transfer
Taxes if such delivery would reduce the amount of Transfer Taxes that would
otherwise be imposed. Any disputes under this provision shall be resolved by the
Neutral Auditors within 30 days of the submission of such dispute.

                  (e) CBS shall terminate and shall cause the termination by the
Closing of any agreement or practice relating to Taxes between CBS or any of its
Affiliates (other than any Investment), on the one hand, and any Investment, on
the other hand. On and after the Closing Date, neither CBS or its Affiliates
(other than any Investment), on the one hand, nor any Investment, on the other
hand, shall have any further rights, obligations, or liabilities under any such
agreement or practice, and no Investment shall have any obligation in respect of
any agreement for practice relating to Taxes for any period prior to or
including the Closing Date.



                                       80
<PAGE>   92

                  (f) At the Closing, CBS shall deliver to Purchaser duly
executed certificates certifying that the transactions contemplated hereby are
exempt from withholding under Section 1445 of the Code.

                  (g) [Intentionally omitted].

                  (h) CBS shall file any amended consolidated, combined or
unitary Income Tax Returns that include the Business or any Sold Subsidiary for
Pre-Closing Tax Periods which are required as a result of examination
adjustments made by any taxing authority as finally determined. For those
jurisdictions in which separate Income Tax Returns are filed by any Sold
Subsidiary, any required amended returns for Pre-Closing Tax Periods resulting
from such examination adjustments, as finally determined, shall be prepared by
CBS and furnished to such Sold Subsidiary, for signature and filing at least ten
days prior to the due date for filing such returns. Purchaser shall file all
other amended Tax Returns relating to the Business.

                  (i) (A) CBS shall file or cause to be filed the United States
consolidated federal Income Tax Return of CBS and, where applicable, all other
consolidated, combined or unitary state or local Income Tax Returns for the
Pre-Closing Tax Periods of each Selling Subsidiary and each Sold Subsidiary and
(B) CBS shall also file and shall cause each Selling Subsidiary and each Sold
Subsidiary to file all other Tax Returns with respect to the Acquired Assets or
the income or operations of the Business required to be filed (including any
extensions) on or prior to the Closing Date. CBS shall prepare or shall cause to
be prepared all Income Tax Returns required to be filed by any Sold Subsidiary
on a separate return basis for Pre-Closing Tax Periods that have not been filed
by the Closing Date and (x) CBS shall provide Purchaser with a copy of all such
Tax Returns (or in the case of a Tax Return that includes assets or businesses
not included in the Acquired Assets, those portions of such Tax Returns that
relate to the Business) at least 30 days prior to the due date for filing such
Tax Returns (including any extensions) and (y) after reviewing and approving
such Tax Returns (which approval shall not be unreasonably withheld), Purchaser
shall file or shall cause such Tax Returns to be filed. All such Tax Returns
that may affect the future Tax payable by Purchaser or any Sold Subsidiary shall
be prepared on a basis consistent with law and past practice. CBS shall pay or
cause to be paid all Taxes shown as due on any such Tax Returns.

                  (j) (i) Purchaser shall timely prepare and file (or cause to
be prepared and filed) all Tax Returns required by Law for all Taxes covering
the Acquired Assets or the Sold Subsidiaries for all Straddle Periods. Purchaser
shall provide CBS with a copy of such Tax Returns at least 30 days prior to the
due date for filing such Tax Returns (including extensions), and after CBS's
review and approval of such Tax Returns (which approval shall not be
unreasonably withheld), Purchaser shall file or cause such Tax Returns to be
filed. Not later than 5 days before the due date for the payment of Taxes with
respect to such Tax Returns, CBS shall pay to Purchaser an amount equal to
Sellers' Straddle Period Taxes determined in accordance with the method
described in clause (iii) below.



                                       81
<PAGE>   93

                  (ii) Purchaser shall prepare and file all Tax Returns other
         than Income Tax Returns for all Sold Subsidiaries that have not been
         filed by the Closing Date.

                  (iii) For purposes of this Agreement, the Taxes allocable to
         Sellers' Straddle Period Tax Returns shall be:

                  (A) In the case of any real or personal property Tax relating
                      to the Acquired Assets or the Subsidiary Assets, an amount
                      equal to the Tax for the entire Straddle Period multiplied
                      by a fraction, the numerator of which is the number of
                      days in the Sellers' Straddle Period and the denominator
                      of which is the number of days in the entire Straddle
                      Period; and

                  (B) In the case of any other Tax, the amount that would be
                      payable if the taxable year ended on the Closing Date.

                  (k) CBS and Purchaser shall each provide the other with such
assistance as may be reasonably requested (including making employees reasonably
available to provide information or testimony) in connection with the
preparation of any Tax Return, any Tax Controversy (as defined in Section
5.14(l)(ii)), or the determination of liability for Taxes with respect to the
Acquired Assets or the income or operations of the Business. Purchaser shall
complete CBS's standard tax packages relating to Tax Returns that CBS is
responsible for filing pursuant to Section 5.14(i) and deliver them to CBS
within 90 days of Purchaser's receipt from CBS and shall, and shall cause its
Affiliates to, cooperate with CBS in preparing and pursuing any claims for
refunds or credits of Taxes (including refunds or credits relating to investment
tax credits, research credits and credits for prepayments of Income Taxes). At
Purchaser's request and expense, CBS shall file claims prepared by Purchaser for
refunds of Taxes (other than items described in Section 2.3(b)(ii) and (iii))
and promptly pay over the amount recovered to Purchaser (without any interest,
other than interest paid by the applicable taxing authority with respect to such
refund); provided, however, that Purchaser shall promptly reimburse CBS to the
extent that such refund is reclaimed by a taxing authority (without any
interest, other than interest due to the applicable taxing authority with
respect to such reclamation). CBS and Purchaser each shall, and shall cause
their Affiliates to, retain until seven years after the Closing Date all Tax
Returns, schedules, work papers and other records that are owned by such Person
immediately after the Closing and that relate to the Business or the Acquired
Assets; after the end of such period, before disposing of any such Tax Returns,
schedules, work papers or other records, each shall give notice to such effect
to the other, and shall give the other, at the other's cost and expense, a
reasonable opportunity to remove and retain all or any part of such Tax Returns,
schedules, work papers or other




                                       82
<PAGE>   94

records as the other may select.

                  (l) (i) Purchaser shall, in the event that Purchaser receives
notice (whether orally or in writing) of any examination, claim, proposed
settlement, proposed adjustment or related matter with respect to any Taxes for
which Purchaser may be indemnified hereunder (the "CBS Tax Controversies")
promptly notify CBS thereof, provided, however, that failure to give such
notification shall not affect the indemnification provided hereunder except to
the extent CBS shall have been actually prejudiced as a result of such failure
(except that CBS shall not be liable for any interest or other expenses incurred
during the period in which the Purchaser failed to give such notice). CBS shall
be entitled at its sole discretion and expense to handle, control and compromise
or settle the CBS Tax Controversies, and shall reasonably inform Purchaser of
the progress of the CBS Tax Controversies, provided, however, that in the event
Purchaser waives its rights to indemnification with respect to any CBS Tax
Controversy relating to Taxes other than Income Taxes, Purchaser may assume at
its expense, and have the sole discretion to handle, control, compromise, or
settle, such controversy.

                  (ii) CBS shall, in the event CBS receives notice (whether
         orally or in writing) of any examination, claim, proposed settlement,
         proposed adjustment or related matter with respect to Taxes
         attributable to the Business (other than CBS Tax Controversies) (the
         "Purchaser Tax Controversies", and together with the CBS Tax
         Controversies, the "Tax Controversies"), promptly notify Purchaser
         thereof, provided, however that failure to give such notification shall
         not affect the indemnification provided hereunder except to the extent
         Purchaser shall have been actually prejudiced as a result of such
         failure (except that the Purchaser shall not be liable for any interest
         or other expenses incurred during the period in which CBS failed to
         give such notice). Purchaser shall be entitled at its sole discretion
         and expense to handle, control and compromise or settle the Purchaser
         Tax Controversies, and shall reasonably inform CBS of the progress of
         the Purchaser Tax Controversies.

                  SECTION 5.15. SUPPLIES. Purchaser shall not use any signs or
stationery, purchase order forms, packaging or other similar paper goods or
supplies, or advertising and promotional materials, product, training and
service literature and materials, or computer programs or like materials
(collectively, the "Supplies"), that state or otherwise indicate thereon that
the Business is a division or unit of CBS, or, except in compliance with any
license agreement contemplated by Section 5.9(b), contain any trademarks,
servicemarks, trade names or corporate or business names, derived from or
including the words "Westinghouse Electric Corporation", "Westinghouse Electric
Company", "Westinghouse", "WELCO" or "Circle W" (in logotype design or any other
style or design) in whole or in part; provided, that to the extent any Supplies
included in the Acquired Assets so indicate, Purchaser may, for a period of 90
days after the Closing Date, use such Supplies after first



                                       83
<PAGE>   95

crossing out or marking over such statement or indication or trademark,
servicemark, trade name or corporate or business name and otherwise clearly
indicating on such Supplies that the Business is no longer a division or unit of
CBS. Purchaser shall not reorder or produce any Supplies which state or
otherwise indicate thereon that the Business is a division or unit of CBS or
contain any such trademarks, servicemarks, trade names or corporate or business
names.

                  SECTION 5.16. TRANSFER OF ASSETS OF SOLD SUBSIDIARIES. On or
prior to the Closing Date, CBS shall cause the Sold Subsidiaries to transfer
(and shall use its reasonable efforts to inform Purchaser of each such transfer
prior thereto), without consideration, any Subsidiary Assets not relating
primarily to the Business (including the assets set forth on Schedule 5.16) to
CBS or Subsidiaries of CBS other than the Sold Subsidiaries or to any third
party designated by CBS. After the Closing, Purchaser will cooperate with CBS to
transfer without consideration at CBS's request any such Subsidiary Assets to
CBS or Subsidiaries of CBS or to any third party designated by CBS and CBS shall
reimburse Purchaser for its reasonable expenses and all Taxes incurred in
connection therewith.

                  SECTION 5.17. REMOVAL OF EXCLUDED ASSETS AND LIABILITIES FROM
SOLD SUBSIDIARIES. The parties acknowledge that the Excluded Assets and Excluded
Liabilities are held by, or are obligations of, certain of the Sold
Subsidiaries. Sellers will at the request of Purchaser use their reasonable best
efforts either (i) to transfer the Acquired Assets held by any such Subsidiary
directly to Purchaser (in which event Sellers will retain the Sold Subsidiary)
or (ii) to transfer out of any such Subsidiary, or otherwise appropriately
protect Purchaser from, any such Excluded Assets and Excluded Liabilities held
by any such Subsidiary, and CBS shall reimburse Purchaser for its reasonable
expenses and all Taxes incurred in connection therewith.

                  SECTION 5.18. CREDIT SUPPORT. Purchaser acknowledges that in
the course of the conduct of the Business, CBS and its Subsidiaries have entered
into and expect to continue to enter into various arrangements (i) in which
guarantees (including guarantees of performance under contracts or agreements),
letters of credit or other credit arrangements, including surety and performance
bonds, were issued by or for the account of CBS and its Subsidiaries or (ii) in
which CBS and its Subsidiaries are the primary or secondary obligors on debt
instruments or financing or other contracts or agreements, in any such case to
support or facilitate business transactions of the Sold Subsidiaries. Such
arrangements by such parties are hereinafter referred to as the "Credit Support
Arrangements". Schedule 5.18 sets forth a list of all Credit Support
Arrangements existing as of the date hereof. Not later than the Closing,
Purchaser will (i) obtain replacement Credit Support Arrangements which will be
in effect at the Closing or (ii) repay, or cause the repayment of, all debt and
other obligations to which such Credit Support Arrangements relate (and cause
the cancellation of such Credit Support Arrangements) or arrange for itself or
one of its Subsidiaries (including the Sold Subsidiaries)



                                       84
<PAGE>   96

to be substituted as the obligor thereon as of the Closing Date. CBS and its
Subsidiaries will cooperate with Purchaser in arranging any such substitution,
provided that neither CBS nor its Subsidiaries shall be required to expend any
material sum in connection therewith.

                  SECTION 5.19. NON-COMPETITION AND CONFIDENTIALITY.

                  (a) For a period of five years from the Closing, CBS shall
not, and shall cause each of the other Sellers and its other Affiliates not to,
directly or indirectly, engage in any business that is in competition with the
Business. Notwithstanding anything to the contrary contained in this Section
5.19, Purchaser hereby agrees that the foregoing covenant shall not be deemed
breached as a result of (i) the ownership by CBS or any Affiliate of CBS of less
than an aggregate of 5% of any class of capital stock of a person engaged,
directly or indirectly, in a business that is in competition with the Business
or less than 10% in value of any instrument of indebtedness of a person engaged,
directly or indirectly, in a business that is in competition with the Business,
(ii) the retention and conduct by CBS of the Process Control Business, the Power
Generation Business and any other business in which it is currently engaged,
(iii) any action taken by CBS or any of its Affiliates pursuant to this
Agreement or a Seller Ancillary Document, (iv) any action taken by CBS or any of
its Affiliates or by any third party at the direction of CBS in connection with
discharging its obligations under any guarantees (including guarantees of
performance under contracts or agreements), assumption of obligations, letters
of credit or other similar arrangements, including surety and performance bonds,
in effect at the Closing Date or (v) the acquisition by CBS or any Affiliate of
CBS of any person (A) which derives less than $10,000,000 in revenues from
businesses in competition with the Business or (B) the predominant business of
which is not in competition with the Business if after such acquisition CBS or
its Affiliates uses reasonable best efforts to divest the business of such
Person that is in competition with the Business within 270 days after the
acquisition of such business.

                  (b) For a period of ten years after the Closing, CBS agrees
to, and to cause each of the other Sellers and its other Affiliates to, maintain
the confidentiality of all confidential information with respect to the Business
and the Acquired Assets, or learned by CBS or any Seller directly or indirectly
from Purchaser, including information with respect to (A) prospective business
activities, (B) sales figures, (C) profit or loss, gross margin or similar
information, and (D) customers, clients, suppliers, sources of supply and
customer lists (the "Confidential Information"), and shall not disclose any
Confidential Information, except (i) in the event CBS or any of its Affiliates
is required to disclose any of such information pursuant to applicable Law or by
applicable legal process, (ii) to the extent such information becomes generally
available to the public other than as a result of a disclosure by CBS or its
Affiliates, (iii) to the extent such information was available to CBS or its
Affiliates on a non-confidential basis prior to its disclosure to CBS or its
Affiliates, or (iv) to the extent such information becomes available to CBS or
its Subsidiaries on a non-confidential basis from



                                       85
<PAGE>   97

a source other than CBS or its Affiliates, provided that such source is not
prohibited from disclosing such information by a contractual, legal or fiduciary
obligation. In the event CBS or any of its Subsidiaries is required to disclose
any of such information pursuant to applicable Law or by applicable legal
process, CBS or its respective Subsidiary shall, to the extent practicable under
the circumstances, inform Purchaser sufficiently in advance of such disclosure
to afford Purchaser the opportunity to resist disclosure and shall use its
reasonable commercial efforts to cooperate with Purchaser in efforts to minimize
the amount of information to be disclosed and to seek to prevent its disclosure
to third parties.

                  (c) For a period of five years after the Closing, neither CBS
nor Purchaser shall, directly or indirectly, knowingly solicit or encourage to
leave the employment of CBS or Purchaser, any employee of Purchaser or the WELCO
divisions of CBS, as the case may be.

                  (d) If CBS or any other Seller breaches, or threatens to
commit a breach of, any of the provisions of Section 5.19(a), (b) or (c) (the
"Restrictive Covenants"), Purchaser shall have the following rights and remedies
(upon compliance with any necessary prerequisites imposed by law upon the
availability of such remedies) , each of which rights and remedies shall be
independent of the other and severally enforceable and shall not be affected by
the provisions of Article VIII, and all of which rights and remedies shall be in
addition to, and not in lieu of, any other rights and remedies available to
Purchaser under Law or in equity:

                  (i) The right to have the Restrictive Covenants specifically
         enforced (without posting any bond) by any court having equity
         jurisdiction, including the right to an entry against CBS of
         restraining orders and injunctions (preliminary, mandatory, temporary
         and permanent) against violations, threatened or actual, and whether or
         not then continuing, of such covenants, it being acknowledged and
         agreed that any such breach or threatened breach may cause irreparable
         injury to Purchaser and that money damages may not provide adequate
         remedy to Purchaser.

                  (ii) The right and remedy to require CBS to account for and
         pay over to Purchaser all compensation, profits, monies, accruals,
         increments or other benefits derived or received by such person as a
         result of any transactions constituting a breach of any of the
         Restrictive Covenants, and such person shall account for and pay over
         such benefits to Purchaser.

                  (e) If any court determines that any of the Restrictive
Covenants, or any part thereof, is invalid or unenforceable, the remainder of
the Restrictive Covenants shall not thereby be affected and shall be given full
effect, without regard to the invalid portions.

                  (f) Notwithstanding the foregoing, nothing contained in the
Agreement shall



                                       86
<PAGE>   98

impair, impede, prevent, inhibit, limit or restrict CBS or any of its Affiliates
(or any successor or assign of any of them) in any manner or respect whatsoever
from (i) the continuing operation of (x) the Power Generation Business, or (y)
the Process Control Business, provided the scope of each of such businesses is
primarily related to the goods and services which it has typically provided
under (x) and (y) or (ii) selling or otherwise transferring the Power Generation
Business or the Process Control Business or any portion thereof to any Person,
whether or not such Person or any of its Affiliates is engaged in a business
competitive with the Business.

                  (g) If any court determines that any of the Restrictive
Covenants, or any part thereof, is unenforceable because of the duration of such
provision or the area covered thereby, such court shall have the power to reduce
the duration or area of such provisions and, in its reduced form, such provision
shall then be enforceable and shall be enforced.

                  SECTION 5.20. RELATED AGREEMENTS. At or prior to the Closing,
CBS and Purchaser agree to enter into the following agreements:

                  (a) TRANSITIONAL SERVICES. CBS and Purchaser shall enter into

businesses within Sellers, including performance obligations under Contracts,
which have not been documented by a formal written agreement. In particular, the

Business and the Power Generation Business. The parties agree that, except for
specific provisions in this Agreement and the Seller Ancillary Documents which
expressly provide for any different treatment, prior to the Closing, the parties
will enter into arrangements, reasonably satisfactory to the parties,
documenting any such pre-existing relationships, including any subcontract
arrangements, which shall be maintained on such documented basis by Purchaser
after the Closing.

                  SECTION 5.22. U.S.-CONTROLLED ENTITY. For at least three

interest therein) at all times be a U.S.-Controlled Entity, shall maintain a
presence in the United States, and shall principally administer the business in
the United States, and (ii) shall not transfer, convey, assign or sell any of
its interest in the Business to a Person which is not a U.S.-Controlled Entity.

obtain and maintain an acceptable Foreign Ownership Control and Influence
determination with the appropriate Governmental Authorities. Purchaser shall,
during such period, take all steps reasonably necessary, as required, to comply
with U.S. requirements with respect to the export of U.S. technology and, upon
request, to provide CBS with reasonable written assurance that such steps have
been taken.

                  SECTION 5.23. INSURANCE MATTERS. CBS shall place its insurers
on notice of all liability and workers' compensation claims which are made prior
to the Closing and property losses to the Acquired Assets occurring prior to the
Closing. Purchaser's rights under Section 2.2(a)(xviii) in respect of insurance
shall be subject to any applicable policy deductibles set forth in Schedule
4.1(i) and co-payments provisions or any payment or reimbursement obligations of
CBS or any of its Affiliates in respect thereof; and Purchaser shall be
responsible for and be entitled to the benefit of any retrospective premium,
cost or benefit associated with claims that are subject of the insurance
proceeds referred to in Section 2.2(a)(xviii). Notwithstanding the above or the
provisions of Section 2.2(a)(xviii), subject to the first sentence of Section
5.1, CBS may, in its sole discretion, liquidate, commute, settle, modify or
amend any of its insurance policies in any respect. No later than thirty (30)
days prior to the Closing, Purchaser shall have the right, and be given access

to) shared technology agreements, business supply agreements and settlement
support agreements to be entered into between CBS and the purchasers of the
Power Generation Business and the Process Control Business (collectively, the
"Third Party Agreements"). It is understood and agreed that if (a) any of the
Third Party Agreements are entered into prior to the Closing substantially in
the



                                       88

obligations thereunder (in each case to the extent rights and obligations relate
to the Business and the Intellectual Property and Technology) and (b) if the
Closing occurs prior to the execution of any of the Third Party Agreements,
Purchaser shall enter into any such Third Party Agreement substantially in the
form previously so provided with the purchaser of the applicable business.

Acquisition Regulation Subpart 9.5 and Department of Energy Acquisition
Regulation Subpart 909.5) with respect to any Government Contracts (or
outstanding bids for Government Contracts) included in the Acquired Assets.

                  SECTION 5.30. GUARANTEE AGREEMENT. Purchaser shall use its

<PAGE>   106

                      breaches if the aggregate amount of such Loss relating to
                      a single claim (or group of claims relating to the same
                      facts or circumstances, event or transaction) does not
                      exceed $15,000;

                  (D) CBS shall not have any Liability under this Section 8.1 to
                      the extent the Liability arises as a result of the
                      operation of the Business or the Acquired Assets after the
                      Closing or any action taken or omitted to be taken by
                      Purchaser or any of its Affiliates;

                  (E) CBS shall not have any Liability in respect of any Losses
                      under clause (v) above except to the extent the aggregate
                      of all such Losses for which CBS, but for this clause (E),
                      would be liable exceeds $12,500,000, in which case, (w)
                      for aggregate Losses of more than $12,500,000 but less
                      than $25,000,000, CBS shall pay 50% of such Losses, (x)
                      for aggregate Losses of $25,000,000 or more but less than
                      $50,000,000, CBS shall pay 75% of such Losses, (y) for
                      aggregate Losses of $50,000,000 or more but less than
                      $100,000,000, CBS shall pay 50% of such Losses and (z) for
                      aggregate Losses of $100,000,000 or more, CBS shall pay
                      100% of all other such Losses;

                  (F) for purposes of calculating Losses under clause (v) above
                      and determining the aggregate of all Losses pursuant to
                      clause (E) of this proviso, CBS shall not have any
                      liability if the aggregate amount of such Loss relating to
                      a single claim (or group of claims relating to the same
                      facts or circumstances, event or transaction) does not
                      exceed $1,000,000; and

                  (G) CBS shall not have any Liability under clause (vi) above
                      except to the extent the aggregate of all Losses relating
                      thereto for which CBS would, but for this proviso, be
                      liable under clause (vi) above exceeds $5,000,000.

                  With respect to Losses for which CBS has Liability pursuant to
Section 8.1(a)(v) and to the extent that such Liability involves the
implementation of a Remedial Action, (i) in no event shall CBS's Liability
extend to Remedial Action that seeks to meet or address cleanup criteria
applicable to real property other than criteria applicable to real property used
for purposes substantially consistent with the purposes for which the Premises
were used by the Business prior to the Closing and (ii) CBS shall have the right
(at its sole cost and expense) to review and provide Purchaser with written
comments in advance of (A) the Purchaser's selection of consultants and
contractors designated to perform the Remedial Action and (B) the development of
the scope of work for, and type of, the Remedial Action to



                                       95
<PAGE>   107

be implemented. Purchaser shall review and reasonably and in good faith consider
CBS's comments. Purchaser shall provide all plans, reports and submissions to
any Governmental Authority regarding any such Remedial Action in draft form to
CBS a reasonable time prior to transmission of such items to such Governmental
Authority and Purchaser shall review and in good faith consider any of CBS's
comments on such plans, reports and submissions. CBS and its representatives
shall have the opportunity to be present and participate at any meetings with
Governmental Authorities.

                  Notwithstanding the foregoing, from and after the time, if
any, as clause (E)(z) of the second preceding paragraph becomes applicable or
could reasonably be expected to become applicable prior to completion of any
specific Remedial Action, all determinations with respect to Remedial Actions
(including those contemplated by the first sentence of the immediately preceding
paragraph) shall be made jointly by CBS and Purchaser acting reasonably and in
good faith. All such determinations shall be made (1) with a view towards
achieving solutions that involve reasonable and customary Remedial Actions that
can be implemented efficiently and cost-effectively, (2) with due regard to
avoiding undue interference with the ongoing business operations of Purchaser
(or its successor in interest) at the Premises and (3) in accordance with
Environmental Laws. If, in such circumstances, (X) CBS and Purchaser do not
agree as to whether Remedial Action or any significant portion of a Remedial
Action is required by an Environmental Law, the parties shall submit such
dispute to arbitration pursuant to Section 8.8 or (Y) CBS and Purchaser do not
agree with respect to the scope of work for, and the type of, the Remedial
Action to be implemented, each of CBS and Purchaser shall submit to the other a
written proposal with respect thereto; if the parties are unable to agree how to
proceed, either party may submit such dispute to arbitration pursuant to Section
8.8.

                  (b) Notwithstanding anything to the contrary contained in this
Article 8, CBS and Purchaser have agreed to allocate responsibility for certain
Assumed Liabilities pursuant to specific provisions of this Agreement. It is the
intent of the parties that such provisions be the sole and exclusive means for
recovery of amounts that otherwise might constitute Losses indemnifiable by CBS
under this Article 8. Accordingly, CBS shall not have any Liability under clause
(i) of Section 8.1(a) for any breach of representation or warranty by CBS
contained in this Agreement if the claim for breach of representation or
warranty relates to any Assumed Liability (including Business-Related
Environmental Liabilities) for which CBS and Purchaser have expressly allocated
responsibility pursuant to the provisions listed in Schedule 8.1(b).

                  (c) Purchaser acknowledges and agrees that its sole and
exclusive remedy with respect to any and all claims relating to the subject
matter of this Agreement (except as provided in Section 5.14) shall be pursuant
to the indemnification provisions set forth in this Section 8.1. In furtherance
of the foregoing, Purchaser hereby waives, to the fullest extent



                                       96
<PAGE>   108

permitted under Law, any and all rights, claims and causes of action it may have
against Sellers, their Affiliates and their respective officers, directors,
employees, stockholders, agents and representatives arising under or based upon
any Law, Environmental Law or otherwise (except pursuant to the indemnification
provisions set forth in this Article 8).

                  SECTION 8.2. INDEMNIFICATION BY PURCHASER. Without limiting
Purchaser's rights under Section 8.1, Purchaser hereby agrees to indemnify
Sellers, their Affiliates and their respective officers, directors, employees,
stockholders, agents and representatives against, and agrees to hold them
harmless from, any Losses, as incurred, (payable quarterly upon written
request), to the extent arising from, relating to or otherwise in respect of:

                  (i) any breach of any representation or warranty of Purchaser
         contained in this Agreement;

                  (ii) any breach of any covenant of Purchaser contained in this
         Agreement or in any Purchaser Ancillary Document;

                  (iii) any Assumed Liabilities;

                  (iv) all Liabilities of the Sold Subsidiaries;

                  (v) all Indebtedness included in the Statement of Net Assets;

                  (vi) any Liability under the WARN Act or similar statute to
         the extent arising from the actions of Purchaser after the Closing;

                  (vii) any Liability under any Credit Support Arrangement
         following the Closing;

                  (viii) any Liability relating to the performance or failure to
         perform under any Contracts, Intellectual Property or Technology
         assigned to Purchaser pursuant to Sections 5.4(b) or 5.4(c) (in the
         case of Section 5.4(c), to the extent Purchaser is provided the
         benefits of any Contract, Intellectual Property or Technology); or

                  (ix) the operation of the Business or the Acquired Assets, or
         any actions or omissions of Purchaser, its Affiliates, agents,
         contractors or subcontractors in connection therewith, after the
         Closing.

                  SECTION 8.3. CHARACTERIZATION OF INDEMNIFICATION PAYMENTS. All
amounts paid by CBS or Purchaser, as the case may be, under this Article 8 shall
be treated as adjustments to the Purchase Price for all Tax purposes.



                                       97
<PAGE>   109

                  SECTION 8.4. LOSSES NET OF INSURANCE; TAX LOSS AND BENEFITS;
NO CONSEQUENTIAL DAMAGES.

                  (a) The amount of any Loss shall be:

                  (i) net of any amounts recovered or recoverable by the
         indemnified party under insurance policies or Government Contracts (it
         being understood that if any amount is recovered or recoverable by
         Purchaser under any insurance policy or Government Contract, it shall
         not be subject to indemnification by CBS under this Article 8) with
         respect to such Loss;

                  (ii) (A) increased to take account of any net Tax cost
         incurred by the indemnified party by reason of the receipt of any
         indemnity payment being treated for Tax purposes as other than an
         adjustment to the Purchase Price (grossed-up for such increase) and (B)
         reduced to take account of any net Tax benefit realized by the
         indemnified party in respect of the taxable year in which such Loss is
         incurred or paid and, with respect to a Tax benefit arising in a year
         subsequent to the year in which the Loss is paid or incurred, the
         indemnified party shall pay to the indemnifying party the amount of
         such Tax benefit at the time such Tax benefit is actually realized,
         arising from the incurrence or payment of any such Loss; and

                  (iii) to avoid double-counting as to any matter, determined
         after giving effect to any reserves on the books of the Business as of
         the Closing Date in respect of such matter if and to the extent such
         reserve was reflected in the Statement of Working Capital or the
         Balance Sheet; provided that this clause (iii) shall not apply in
         determining the amount of any Loss for purposes of clause (v) or (vi)
         of Section 8.1(a).

                  (b) In computing the amount of any such Tax cost or Tax
benefit, the indemnified party shall be deemed to recognize all other items of
income, gain, loss, deduction or credit before recognizing any item arising from
the receipt of any indemnity payment hereunder or the incurrence or payment of
any indemnified loss, liability, claim, damage or expense. Notwithstanding
anything to the contrary contained herein, no indemnification shall be provided
for under this Article 8 in respect of any indirect, special, consequential or
"business interruption" damages.

                  (c) Purchaser shall use its commercially reasonable efforts
consistent with past practice in relation to the GESCO Businesses to pursue any
and all rights to reimbursement, recovery or indemnification for Losses pursuant
to any Government Contract prior to bringing any claim against CBS under this
Article 8.



                                       98
<PAGE>   110

                  (d) Notwithstanding anything to the contrary in this Agreement
and the ESBU Asset Purchase Agreement, neither CBS nor Purchaser shall have any
Liability for Losses indemnifiable under Article 8 of either agreement to the
extent such party has previously been indemnified with respect to such Losses
pursuant to Article 8 of the other agreement.

                  SECTION 8.5. TERMINATION OF INDEMNIFICATION.

                  The obligations to indemnify and hold harmless any party, (a)
pursuant to clause (a)(i) of Section 8.1 and clause (a)(i) of Section 8.2, shall
terminate when the applicable representation or warranty terminates pursuant to
Section 9.3; provided, however, that such obligations to indemnify and hold
harmless shall not terminate with respect to any item as to which the Person to
be indemnified shall have, before the expiration of the applicable period,
previously made a claim by delivering a notice pursuant to Section 5.14(l), 8.6
or 8.7 (stating in reasonable detail the basis of such claim) to the party to be
providing the indemnification; (b) pursuant to clause (a)(v)(B) of Section 8.1,
shall terminate on the eighth anniversary of the Closing Date; (c) pursuant to
clause (a)(vi) of Section 8.1, shall terminate on the fourth anniversary of the
Closing Date; (d) pursuant to clause (a)(vi) of Section 8.1, shall terminate on
the fourth anniversary of the Closing Date; and (e) pursuant to the other
clauses of Sections 8.1 and 8.2 shall not terminate.

                  SECTION 8.6. PROCEDURES RELATING TO THIRD PARTY CLAIMS (OTHER
THAN TAX CONTROVERSIES AND ENVIRONMENTAL LIABILITIES).

                  (a) In order for a Person (the "indemnified party"), to be
entitled to any indemnification provided for under this Agreement in respect of,
arising out of or involving a claim made by any Person against the indemnified
party (other than a Tax Controversy or Environmental Liability, procedures for
which are specified in Section 5.14(l) in the case of Tax Controversies and
Section 8.9 in the case of Environmental Liabilities) (a "Third Party Claim"),
such indemnified party must notify the indemnifying party in writing, and in
reasonable detail, of the Third Party Claim within 10 business days after
receipt by such indemnified party of notice of the Third Party Claim; provided,
however, that failure to give such notification shall not affect the
indemnification provided hereunder except to the extent the indemnifying party
shall have been actually prejudiced as a result of such failure, including loss
of any rights of subrogation (except that the indemnifying party shall not be
liable for any expenses incurred during the period in which the indemnified
party failed to give such notice). Thereafter, the indemnified party shall
deliver to the indemnifying party, promptly after the indemnified party's
receipt thereof, copies of all notices and documents (including court papers)
received by the indemnified party relating to the Third Party Claim.

                  (b) If a Third Party Claim is made against an indemnified
party, the



                                       99
<PAGE>   111

indemnifying party will be entitled to participate in the defense thereof and,
if it so chooses, to assume the defense thereof with counsel selected by the
indemnifying party. If the indemnifying party so elects to assume the defense of
a Third Party Claim, the indemnifying party will not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party assumes such defense, the indemnified party shall have the right to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the indemnifying party, it being
understood that the indemnifying party shall control such defense. The
indemnifying party shall be liable for the fees and expenses of counsel employed
by the indemnified party for any period during which the indemnifying party has
not assumed the defense thereof (other than during any period in which the
indemnified party shall have failed to give notice of the Third Party Claim as
provided above). If the indemnifying party chooses to defend or prosecute a
Third Party Claim, all the parties hereto shall cooperate in the defense or
prosecution thereof. Such cooperation shall include the retention and (upon the
indemnifying party's request) the provision to the indemnifying party of records
and information which are reasonably relevant to such Third Party Claim, and
making employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder. If the
indemnifying party chooses to defend or prosecute any Third Party Claim, the
indemnified party will agree to any settlement, compromise or discharge of such
Third Party Claim which the indemnifying party may recommend, which involves no
order for non-monetary relief, will not result in the indemnified party being
bound by principles of res judicata or collateral estoppel in defending other
similar claims and which by its terms obligates the indemnifying party to pay
the full amount of the liability in connection with such Third Party Claim or,
if such settlement, compromise or discharge does not require full payment of
such liability, the indemnified party shall have the right to consent to such
settlement, compromise or discharge, which consent may not be unreasonably
withheld. Whether or not the indemnifying party shall have assumed the defense
of a Third Party Claim, the indemnified party shall not admit any liability with
respect to, or settle, compromise or discharge, such Third Party Claim without
the indemnifying party's prior written consent (which consent shall not be
unreasonably withheld).

                  SECTION 8.7. PROCEDURES RELATING TO NON-THIRD PARTY CLAIMS. In
order for an indemnified party to be entitled to any indemnification provided
for under this Agreement in respect of a claim that does not involve a Third
Party Claim, Tax Controversy or Environmental Liability being asserted against
or sought to be collected from such indemnified party, the indemnified party
shall deliver notice of such claim with reasonable promptness to the
indemnifying party. The failure by any indemnified party so to notify the
indemnifying party shall not relieve the indemnifying party from any liability
which it may have to such indemnified party under this Agreement, except to the
extent that the indemnifying party shall have been actually prejudiced by such
failure. If the indemnifying party does not notify the indemnified party within
30 calendar days following its receipt of



                                      100
<PAGE>   112

such notice that the indemnifying party disputes its liability to the
indemnified party under this Agreement, such claim specified by the indemnified
party in such notice shall be conclusively deemed a liability of the
indemnifying party under this Agreement and the indemnifying party shall pay the
amount of such liability to the indemnified party on demand or, in the case of
any notice in which the amount of the claim (or any portion thereof) is
estimated, on such later date when the amount of such claim (or such portion
thereof) becomes finally determined. If the indemnifying party has timely
disputed its liability with respect to such claim, as provided above, the
indemnifying party and the indemnified party shall proceed in good faith to
negotiate a resolution of such dispute and, if not resolved through
negotiations, subject to Section 9.8, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction.

                  SECTION 8.8. ARBITRATION OF CERTAIN ENVIRONMENTAL LIABILITIES.

                  Any dispute as to the scope of work or the type of Remedial
Action or whether a cost or Loss is a Decontamination and Decommissioning
Liability shall be settled by arbitration in accordance with the Commercial
Rules of the American Arbitration Association. Any party may commence
arbitration hereunder by delivering notice to the other party or parties to the
dispute, claim or controversy. The arbitration panel shall consist of three
arbitrators. Within 10 days after delivery of the notice of commencement of
arbitration referred to above, the Purchaser and CBS shall each appoint one
arbitrator, and the two arbitrators so appointed shall within 10 days of their
appointment designate a third arbitrator within ten days of their appointment.
If the arbitrators designated by the parties to the arbitration are unable or
fail to agree upon the third arbitrator, the third arbitrator shall be
designated by the American Arbitration Association under its rules. The
arbitrators will be bound by the substantive law of the State of New York, but
will not be bound by the laws of evidence and procedure customary in courts of
law. The arbitrators shall be required to submit a written statement of their
findings and conclusions. The award of the arbitrators shall be final, binding
and conclusive on the parties; provided that, where a remedy for breach is
prescribed hereunder or limitations on remedies are prescribed, the arbitrators
shall be bound by such restrictions. Judgment upon the award may be entered in
any court having jurisdiction thereof. The arbitration proceedings shall be
conducted in New York, New York. Unless otherwise determined by the arbitrator
(which determination shall be final and binding on the Purchaser and CBS), each
party shall pay its own expenses of arbitration and the expenses of the
arbitrators shall be shared equally by the Purchaser, on the one hand, and CBS
involved in such arbitration, on the other hand.

                  SECTION 8.9. PROCEDURES RELATING TO CLAIMS CONSTITUTING AN
ENVIRONMENTAL LIABILITY.

                  (a) After the Closing, each of Purchaser and CBS shall notify
(the



                                      101
<PAGE>   113

"Notifying Party") the other in writing, and in reasonable detail, of any claim
in respect of, arising out of or involving a claim made by any Person against
the Notifying Party constituting an Environmental Liability or a breach of the
representations and warranties contained in Section 4.1(j)(B) (to the extent
related to Business-Related Environmental Liabilities) or Section 4.1(n) (a
"Shared Claim"), within 10 business days after receipt by the Notifying Party of
written notice of the Shared Claim; provided, however, that failure to give such
notification shall not affect the indemnification provided hereunder except to
the extent the other party shall have been actually prejudiced as a result of
such failure (except that the other party shall not be liable for any expenses
incurred during the period in which the Notifying Party failed to give such
notice). Thereafter, each party shall deliver to the other party, promptly after
such party's receipt thereof, copies of all notices and documents (including
court papers) received by the such party relating to the Shared Claim.

                  (b) Subject to the provisions of Sections 8.1(a) with respect
to Remedial Actions, during the period from the date hereof to the Closing Date,
Purchaser and CBS shall negotiate in good faith and enter into one or more
agreements governing defense of Shared Claims, it being agreed that any such
agreement shall provide that:

                  (i) Purchaser and CBS will each be entitled to participate in
         the defense of any Shared Claim; provided, however, that if CBS shall
         have one hundred percent of the liability in respect thereof pursuant
         to Section 8.1(a)(v) such claim shall be treated as a Third Party Claim
         under Section 8.6;

                  (ii) Purchaser and CBS will each cooperate in the defense or
         prosecution of any Shared Claim, including the retention and (upon
         request) the provision to the requesting party of records and
         information which are reasonably relevant to such Shared Claim, and
         making employees (including any Business Employees familiar with such
         Shared Claim) available on a mutually convenient basis to provide
         additional information and explanation of any such records and
         information;

                  (iii) Purchaser and CBS will consult with each other and shall
         mutually agree on any significant strategic decisions in respect of any
         Shared Claim;

                  (iv) Purchaser and CBS will consult with each other and shall
         mutually agree on any settlement, compromise or discharge of any Shared
         Claim;

                  (v) neither Purchaser nor CBS shall admit any liability with
         respect to, or settle, compromise or discharge, any Shared Claim
         without the other party's prior written consent (which consent shall
         not be unreasonably withheld); and

                  (vi) appropriate and mutually agreeable arrangements with
         respect to day-to-



                                      102
<PAGE>   114

         day administration of any Shared Claim shall be provided for in such
         agreements.

                  SECTION 8.10. SUBROGATION. (a) Without limiting Purchaser's
indemnification obligations pursuant to Section 8.2, in connection with any
defense in respect of, arising out of or involving a claim by any Person against
Sellers or any of their Affiliates, Sellers and their Affiliates shall be
subrogated to the rights of Purchaser under any Contracts included in the
Acquired Assets (including rights to indemnification and reimbursement).

                  (b) To the extent that Purchaser has refrained from, delayed
or abandoned pursuing any rights to reimbursement, recovery or indemnification
for Losses pursuant to any Contract with respect to any Losses subject to
indemnification by Purchaser pursuant to Section 8.2, Sellers or their
Affiliates shall have the right, at their election, to commence or assume a
claim or course of action in Purchaser's name with respect to any of Purchaser's
rights subrogated hereunder.

Each such notice or other communication shall be given (i) by hand delivery,
(ii) by nationally recognized courier service or (iii) by telecopy, receipt
confirmed. Each such notice or communication shall be effective (i) if delivered
by hand or by nationally recognized courier service, when delivered at the
address specified in this Section 9.1 (or in accordance with the latest
unrevoked direction from such party) and (ii) if given by telecopy, when such

                  SECTION 9.2. INTERPRETATION. The Exhibits and Schedules are
part of this Agreement as if fully set forth in this Agreement. When a reference
is made in this Agreement to a Section, Schedule or Exhibit, such reference
shall be to a Section of, or a Schedule or Exhibit to, this Agreement unless
otherwise indicated. The table of contents and headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement. For purposes of any indemnification
provision in this Agreement, the word "expenses" shall mean out-of-pocket
expenses, and shall not include any allocations of internal salaries and other
expenses. Whenever the words "included", "includes" or "including" are used in
this Agreement, they shall be deemed to be followed by the words "without
limitation". Whenever the word "material" is used in this Agreement (except when
used with respect to the Purchaser), it shall mean material to the Business or
financial condition of the Business, taken as a whole. Whenever reference is
made to "knowledge" with respect to any Seller, it shall mean the actual
knowledge of the Persons named on Schedule 9.2. Any matter set forth in any
Schedule shall be deemed set forth in all other Schedules to the extent
relevant.

                  SECTION 9.3. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND
COVENANTS. The representations and warranties contained in this Agreement
(including the representation and warranty contained in the penultimate sentence
of Section 4.1(h)) shall survive the Closing solely for purposes of Article 8
and shall terminate at the close of business 18 months following the Closing
Date; provided, however, that (i) the representations and warranties contained
in Sections 4.1(a), 4.1(b), 4.1(f) and 4.1(g) (but only to the extent Section
4.1(g) relates to matters of title) shall survive indefinitely; (ii) the
representations and warranties contained in Section 4.1(c)(i) shall survive
until the third anniversary of the Closing Date; (iii) the representations and
warranties contained in Section 4.1(m) and Section 4.1(j)(B) shall survive until
the close of business 30 months following the Closing Date; and (iv) the
representations and warranties contained in Section 4.1(o), to the extent that
such representations and warranties relate to Income Taxes, shall terminate on
the Closing Date. The covenants contained in this Agreement, except as otherwise
expressly provided, shall survive the Closing indefinitely; provided, however,
that the covenants contained in Sections 5.1, 5.2, 5.3(a) and 5.3(b) shall
terminate on the Closing Date.

                  SECTION 9.4. SEVERABILITY. If any provision of this Agreement
(or any



                                      105
<PAGE>   117

portion thereof) or the application of any such provision (or any portion
thereof) to any Person or circumstance shall be held invalid, illegal or
unenforceable in any respect by a court of competent jurisdiction, such
invalidity, illegality or unenforceability shall not affect any other provision
hereof (or the remaining portion thereof) or the application of such provision
to any other Persons or circumstances.

                  SECTION 9.5. COUNTERPARTS. This Agreement may be executed in
two or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when one or more counterparts have been
signed by each of the parties and delivered (including by telecopy) to the other
party.

                  SECTION 9.6. ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES.
Except as expressly otherwise agreed in writing by the parties hereto, this
Agreement, the Guarantee Agreement, the Novation Agreements and the
Confidentiality Agreements (a) constitute the entire agreement between the
parties hereto pertaining to the subject matter hereof and supersede all prior
agreements and understandings, negotiations and discussions, whether written and
oral, among the parties with respect to the subject matter hereof, and there are
no warranties, representations or other agreements between the parties hereto in
connection with the subject matter hereof, except as specifically set forth in
this Agreement, the Guarantee Agreements, and the Confidentiality Agreements and
(b) except as provided in Article 8, are not intended to confer upon any Person
other than the parties hereto (and the Selling Subsidiaries) and their
successors and permitted assigns any rights or remedies hereunder.

                  SECTION 9.7. GOVERNING LAW. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of New York
applicable to contracts made and to be performed entirely in the State of New
York, regardless of the laws that might otherwise govern under applicable
principles of conflict of laws.

                  SECTION 9.8. MEDIATION; CONSENT TO JURISDICTION.

                  (a) Except as provided in Section 8.8, any dispute among the
parties arising out of or in connection with this Agreement or any other
agreement, instrument or other document delivered pursuant to this Agreement, or
any alleged breach hereof or thereof (other than (i) a dispute arising under or
with respect to Section 5.19 or the confidentiality obligations set forth in the
second penultimate sentence of Section 5.2(a) or (ii) a dispute in respect of
which there is a reasonable likelihood of irreparable harm (as to which a party
may seek a temporary restraining order or injunctive relief)) shall be submitted
for discussion and possible resolution by senior officers or designated
spokesperson of each such party.

                  (b) If within a period of 15 days after submission of a matter
in accordance with clause (a) hereof the respective senior officers and
designated spokespersons are unable to



                                      106
<PAGE>   118

agree upon a resolution, any party may within 15 days after the aforesaid 15-day
period elect to utilize a non-binding resolution procedure whereby each party
presents its case at a hearing held in New York, New York before a neutral
advisor, who shall be selected from the CPR Institute For Dispute Resolution.
The parties shall bear their respective costs incurred in connection with this
procedure including the fees and expenses of the neutral advisor. Prior to the
hearing, the parties and the neutral advisor shall use their reasonable best
efforts to agree on a set of ground rules for the hearing. At the closing of the
hearing, the senior executive officers of the respective parties shall meet and
attempt to resolve the matter. Only after the foregoing procedure has been
exhausted shall either party resort to litigation as the final adjudication of
the dispute.

                  (c) Each of Purchaser and CBS irrevocably submits to the
non-exclusive jurisdiction of (i) the Supreme Court of the State of New York,
New York County, and (ii) the United States District Court for the Southern
District of New York located in the Borough of Manhattan in the City of New
York, for the purposes of any suit, action or other proceeding arising out of
this Agreement or any transaction contemplated hereby. Each of the Purchaser and
CBS further agrees that service of any process, summons, notice or document by
U.S. registered mail to such party's respective address set forth in Section 9.1
or, in the case of Purchaser, to its agent for service of process shall be
effective service of process for any action, suit or proceeding in New York with
respect to any matters to which it has submitted to jurisdiction as set forth
above. Each of Purchaser and CBS irrevocably and unconditionally waives any
objection to the laying of venue of any action, suit or proceeding arising out
of this Agreement or the transactions contemplated hereby in (x) the Supreme
Court of the State of New York, New York County, or (y) the United States
District Court for the Southern District of New York, and hereby further
irrevocably and unconditionally waives and agrees not to plead or claim in any
such court that any such action, suit or proceeding brought in any such court
has been brought in an inconvenient forum.

                  SECTION 9.9. PUBLICITY. From the date of this Agreement
through the Closing, neither CBS, on the one hand, nor Purchaser, on the other
hand, shall issue or cause the publication of any press release or other public
announcement with respect to the transactions contemplated by this Agreement
without the consent of the other party, which consent shall not be unreasonably
withheld. If one party provides a copy of its proposed press release or public
announcement to the other party, and the other party does not object or comment
on the proposal within forty-eight hours of receipt, such failure to comment
will be treated as consent to publication by the recipient. If such release or
announcement is required by Law or the rules or regulations of a national
securities exchange in the United States, the party required to make the release
or announcement shall allow the other party reasonable time to comment on such
release or announcement in advance of its issuance. The parties will agree on an
appropriate procedure to implement the requirements of this Section 9.9.

                  SECTION 9.10. ASSIGNMENT. Neither this Agreement nor any of
the rights, interests or obligations hereunder shall be assigned by any party
hereto without the prior written consent of the other party, except that, so
long as any such assignment would not delay or impede the consummation of the
transactions contemplated hereby, Purchaser may assign to one or more Purchaser
Affiliates the right to acquire part or all of the business and assets of the
Business hereunder, together with the other rights of Purchaser hereunder with
respect thereto; provided, however, that any such assignment shall not release
Purchaser from any Liability hereunder (including any Liability under Article 8)
or enlarge or enhance Purchaser's rights or affect any limitations on CBS's
Liability under Article 8. Subject to the preceding sentence, this Agreement
will be binding upon, inure to the benefit of and be enforceable by the parties
and their respective successors and assigns.

                  SECTION 9.11. WAIVER OF JURY TRIAL; TRIAL COSTS. Each of
Purchaser and the Sellers, for themselves and their respective Affiliates,
hereby irrevocably waives all right to trial by jury in any action, proceeding
or counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to the actions of Purchaser and the Sellers or their respective
Affiliates pursuant to this Agreement in the negotiation, administration,
performance or enforcement thereof. The party in whose favor a final judgment is
rendered shall be entitled to reasonable costs and reasonable attorneys' fees.
