ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

As of April 23, 1998, RSL COM U.S.A., Inc., a subsidiary of RSL Communications,
Ltd. ("RSL"), entered into an agreement (the "Asset Purchase Agreement") with
CBS Corporation ("CBS") to acquire substantially all of the business and assets
of Westinghouse Communications, a division of CBS Corporation ("Westinghouse"),
for approximately $90 million in cash plus the assumption of certain
liabilities, subject to customary conditions to closing, including the receipt
of various regulatory and other consents.

On July 14, 1998 (the "Closing Date"), RSL completed the acquisition of
substantially all of the business and assets of Westinghouse. The business
consists primarily of Westinghouse's customer base and telecommunication
products and services, including voice services, data services, outsourcing
services, LAN management and system design (the "Business"). The purchase price
for the assets was $90 million, which was paid in cash, plus the assumption of
certain liabilities of CBS. RSL has recorded this transaction under the purchase
accounting method. The purchase price was paid from RSL's available cash.

The terms of the Asset Purchase Agreement, including the amount of the purchase
price, were negotiated by the parties on an arm's length basis. The purchase
price paid for the assets may be adjusted after the Closing Date in accordance
with the terms of the Asset Purchase Agreement. RSL intends to continue to
utilize the assets purchased in its business.

      1.3. Purchase Price.

            1.3.1. Purchase Price. Subject to the adjustment pursuant to Section
1.4, the purchase price for the Purchased Assets shall be the sum of Ninety
Million Dollars ($90,000,000) (the "Purchase Price"), together with assumption
of the Assumed Liabilities.

            1.3.2. Payment of Purchase Price. At Closing, Buyer shall pay to
Seller an amount equal to the Purchase Price (the "Closing Payment") by wire
transfer of immediately available funds to the bank account set forth on a
notice given by Seller to Buyer not later than three (3) business days prior to
Closing.

            1.3.3. Allocation of Purchase Price. As soon as practicable, but not
later than one hundred twenty (120) days after the Closing Date, Buyer and
Seller shall agree upon the allocation of the Purchase Price (and all other
capitalizable costs) and Assumed Liabilities among the Purchased Assets, and
shall set forth such allocation on a statement (the "Allocation Statement"). The
Allocation Statement shall reflect any changes in the assets and liabilities
shown on the final Statement of Working Capital, whether or not such changes
result in an adjustment to the Purchase Price. If the Parties fail to agree on
the allocation of the Purchase Price within one hundred twenty (120) days after
the Closing Date, then the disagreement shall be resolved as soon as practicable
thereafter, but not later than one hundred eighty (180) days after the Closing
Date, by one of the largest five (5) national accounting firms, which accounting
firm shall be jointly selected by the Parties. The Parties acknowledge that the
scope of such accounting firm's work shall be limited to resolving only those
items to which the Parties do not agree regarding the allocation of the Purchase
Price. The decision of the accounting firm shall be final and binding upon the
Parties. The Parties shall share equally the fees, costs and expenses of the
accounting firm selected to resolve any disagreements regarding the Allocation
Statement. Buyer and Seller shall file all Income Tax Returns, and execute such
other documents as may be required by any taxing authority, in a manner
consistent with the Allocation Statement. Buyer and Seller shall prepare
Internal Revenue Service Form 8594 pursuant to Section 1060 of the Code 


                                       3
<PAGE>

relating to the transactions contemplated by this Agreement based on the
Allocation Statement, and shall deliver such form to each other. Buyer and
Seller shall file such form with each relevant taxing authority. The Allocation
Statement shall have no impact on the Statement of Working Capital for purposes
of calculating the Adjusted Purchase Price.

      1.4. Purchase Price Adjustment.

            1.4.1. Statement of Working Capital. Within seventy-five (75) days
after the Closing Date, Seller shall at its expense prepare and deliver to Buyer
a statement (the "Statement of Working Capital") setting forth Working Capital
(as defined below) as of the close of business on the Closing Date ("Closing
Working Capital"), together with an audited special purpose report of the
Seller's independent auditors that the Statement of Working Capital has been
prepared in compliance with the requirements of this Section 1.4. Buyer shall
cause its employees to assist Seller in the preparation of the Statement of
Working Capital and shall provide Seller on-site access upon reasonable
telephonic notice and at all reasonable times to the personnel, properties,
books and records relating to the Business for such purpose. Buyer acknowledges
that Seller shall have the primary responsibility for preparing the Statement of
Working Capital.

            1.4.2. Review by Buyer. During the 30-day period following Buyer's
receipt of the Statement of Working Capital, Buyer and its independent auditors,
if any, shall be permitted to review and make copies reasonably required of (i)
the working papers of Seller and the non-proprietary working papers of Seller's
independent auditors used in connection with the preparation of the Statement of
Working Capital and (ii) any supporting schedules, analyses and other
documentation relating to the Statement of Working Capital. The Statement of
Working Capital shall become final and binding upon the parties on the thirtieth
(30th) day following delivery thereof, unless Buyer gives written notice of its
disagreement with the Statement of Working Capital ("Notice of Disagreement") to
Seller prior to the close of business on the last day of such 30-day period. 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 Closing Working Capital not being calculated in accordance
with this Section 1.4, and (C) be accompanied by a signed certificate by Buyer
that it has complied with the covenants set forth in Section 1.4.6. If a Notice
of Disagreement complying with the preceding sentence is received by Seller in a
timely manner, then the Statement of Working Capital (as revised in accordance
with the clause (I) or (II) below) shall become final and binding upon the
parties on the earlier of (I) the date Seller and Buyer 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).

            1.4.3. Resolution. During the 30-day period following the delivery
of a Notice of Disagreement that complies with the preceding paragraph, Seller
and Buyer shall seek in good faith to resolve in writing any differences that
they may have with respect to the matters specified in the Notice of
Disagreement. During such period Seller and its independent auditors shall have
reasonable on-site access upon reasonable telephonic notice and during normal
business hours to the personnel, properties, books, records, schedules, analyses
and working papers relating to the Business and shall be permitted to review and
make copies reasonably required of (i) the working 


                                       4
<PAGE>

papers of Buyer and the non-proprietary working papers of Buyer's independent
auditors, if any, and (ii) any supporting schedules, analyses or other
documentation relating to the preparation of the Notice of Disagreement. If, at
the end of such 30-day period, Seller and Buyer have not so resolved such
differences, Seller and Buyer shall submit to an independent public accounting
firm agreed upon by the parties hereto in writing (the "Accounting Firm") for
the review and resolution any and all matters which remain in dispute and which
were properly included in the Notice of Disagreement. Seller and Buyer 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. Seller and Buyer 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. The cost of any
dispute settlement (including the fees and expenses of the Accounting Firm)
pursuant to this Section 1.4 shall be borne by Seller and Buyer in inverse
proportion as they may prevail on matters resolved by the Accounting Firm, which
proportion 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.

            1.4.4. Adjustment. The Purchase Price shall be increased by the
amount by which Closing Working Capital exceeds $1,234,000 as calculated
pursuant to Schedule 1.4 hereto (the "Target Amount"), and the Purchase Price
shall be decreased by the amount by which Closing 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"). If the Purchase
Price is less than the Adjusted Purchase Price, Buyer shall, and if the Purchase
Price is greater than the Adjusted Purchase Price, Seller 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, in the event
that Buyer delivers a Notice of Disagreement to Seller in accordance with this
Section 1.4 and either Seller or Buyer shall be required to make a payment to
the other regardless of the resolution of the items contained in the Notice of
Disagreement, then Seller or Buyer, as applicable, shall, within 10 business
days of the receipt of the Notice of Disagreement, make payment to the other by
wire transfer in immediately available funds of the lesser of the two amounts
that may be owed by Seller or Buyer, as applicable, pending resolution of the
items contained in the Notice of Disagreement together with interest thereon at
the Rate on the date of the Notice of Disagreement, calculated as described
above, and such payment (excluding interest) shall be credited against the
payment excluding interest required pursuant to the second sentence of this
Section 1.4.4.

            1.4.5. Certain Terms. 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 on the Balance Sheet Date (as defined
in Section 2.4.) plus an adjustment of $180,000 for accrued liabilities for
workers' compensation and incurred but not reported medical claims. The terms
"Total Current Assets" and "Total Current Liabilities" shall mean the


                                       5
<PAGE>

combined total current assets and combined total current liabilities determined
in accordance with GAAP (it being understood that (a) (i) cash (on hand or in
banks) and cash equivalents, (ii) pension liabilities, other post-retirement and
post-employment liabilities, (iii) Shortfall Liability, and (iv) amounts
attributable to current and deferred Income Taxes for all periods prior to the
Closing Date for which Seller is liable under Section 1.6, collectively, shall
be excluded in determining Total Current Assets and Total Current Liabilities,
(b) current assets (other than accounts receivable) and liabilities relating to
any Contracts of the Business that are not Assumed Contracts shall be excluded
from the determination of Total Current Assets and Total Current Liabilities,
(c) accrued current liabilities for workers' compensation and incurred but not
reported medical claims shall be included as a liability in the determination of
Total Current Liabilities and (d) the amount of early termination fees collected
by Seller prior to the Closing Date pursuant to any Telecom Contract terminated
by the customer between the date of this Agreement and the Closing Date (as
reduced by any portion thereof used to satisfy any outstanding accounts
receivable of such customer) shall be included as a current liability in the
determination of Total Current Liabilities), respectively, of the Business,
using the same methodologies (including the same bases for judgments except to
reflect changes in specific identifiable events, facts and circumstances),
practices, accounting applications and assumptions, including actuarial
estimates, as used in determining the Target Amount. The Total Current Assets
and Total Current Liabilities shall not include any Excluded Assets or Excluded
Liabilities, respectively. The Parties agree that the adjustment contemplated by
this Section 1.4 is intended to show the change in Working Capital (subject to

Employee Benefit Plan to be made on or prior to the date hereof by Seller to an
Employee Benefit Plan have been or will be made within the time prescribed by
the applicable Law, or Employee Benefit Plan. As of the date hereof, there does
not exist any accumulated funding deficiency within the meaning of either
Section 412 of the Code or Section 302 of ERISA as to any Employee Benefit Plan,
nor would there exist any such deficiency but for the application of an
alternative minimum funding standard. On or prior to the date hereof, there has

with respect to any such Employee Benefit Plan. Except as listed on Schedule
2.17.4, on the date hereof the fair market value of the assets of each Employee
Benefit Plan that is a funded defined benefit pension plan equals or exceeds the
actuarial present value of all accrued benefits under such Employee Benefit
Plan, including early retirement subsidies, plant closing benefits and all other
amounts considered to be benefit liabilities upon a standard termination of a
defined benefit plan subject to Title IV of ERISA, with the said actuarial
present value being determined by application of the actuarial methods and
assumptions applied by such Employee Benefit Plan's enrolled actuary at the most
recent annual valuation of such Employee Benefit Plan, plus all administrative
expenses, fiduciaries' fees and similar charges payable by such Employee Benefit
Plan, plus all Taxes, if any, payable from plan assets.

hereof, (a) except as listed on Schedule 2.17.5, no Employee Benefit Plan is a
"multiple employer" plan within the meaning of Section 4063 or 4064 of ERISA,
(b) no Employee Benefit Plan is a "multiemployer plan" within the meaning of
Section 4001(a)(3) of ERISA or other applicable employee benefit legislation,
(c) Seller does not have either primary or secondary liability under the
provisions of Section 4204 of ERISA or any agreement entered into in accordance
with the provisions of that Section and (d) Seller has not (i) engaged in any
transaction that could result in the imposition of any material liability
pursuant to Section 4069 or 4212 of ERISA or (ii) incurred any material
liability under or pursuant to Title I or IV of ERISA or the penalty or excise
tax provisions of the Code relating to employee benefit plans, and no event or
condition exists with respect to the operations of the Business that may result
in the imposition of any material liability with respect to Buyer pursuant to
Title I or IV of ERISA or the penalty or excise tax provisions of the Code
relating to Employee Benefit Plans.

            2.17.6. Acceleration of Benefits. Except as listed on Schedule
2.17.6, the consummation of the transactions contemplated by this Agreement will
not (a) provided Buyer fully complies with its obligations under Section 11,
entitle any Employee or former Employee to severance, shutdown or permanent job
separation pay or similar termination payments under any Employee Benefit Plan,
or (b) result in any increase in the amount of compensation or benefits payable
by Seller or accelerate the vesting or timing of payment of any benefits payable
by Seller to or in respect of any Employee or former Employee or the beneficiary
or dependent of any Employee or former Employee.

      2.18. Taxes.

makes no express or implied representation or warranty in this Agreement

obtain any Consent. From and after the date hereof, Seller shall permit Buyer to
discuss with the Employees listed on Schedule 2.3 hereto the terms and
conditions of the offer of continued employment with respect to the Business
which Buyer will make to such Employees following the Closing Date, provided
that (i) such discussions shall not relieve Buyer of its obligations with
respect to such Employees pursuant to Article 11 hereof, (ii) the retention or
non-retention of any such Employees after the Closing Date shall not be a
condition to Buyer's obligations hereunder, and (iii) all such discussions shall
be subject to the non-solicitation covenants of the Confidentiality Agreement
(except to the extent permitted by this Section 4.1). All such discussions shall
take place at reasonable times and on reasonable notice to Seller, and shall not
unduly interfere with the conduct or operation of the Business by Seller. In
addition, if Seller intends to provide any written notice to the Employees
regarding Buyer or Buyer's intentions with respect to providing offers of
employment to the Employees or the terms and conditions to be offered by Buyer
to the Employees pursuant to Section 11.1, Seller shall provide Buyer with a

such reports are provided to the management of WestComm. Buyer shall have the
right, (a) in the presence of Seller's representative, to discuss with the
Employees listed on Schedule 2.3 issues reasonably related to the integration of

President, on a weekly basis, issues related to the operation of the Business
(and, if discussion of such issues reasonably requires the 


                                       20
<PAGE>

participation of other management personnel of WestComm, WestComm's President
shall make such other management personnel available for such purpose), provided
that such discussions will not unduly interfere with the conduct or operation of
the Business of Seller. Seller shall respond to any request by Buyer for
information pursuant to this Section 4.2 within three (3) business days. Buyer
agrees that all information pertaining to the Business which has been or is
hereafter disclosed to Buyer remains subject to the terms of the Confidentiality

reasonable efforts to: (a) preserve the relationships with its Employees and

Business in the ordinary course and consistent with past practices.

            4.3.2. Prohibited Actions. Except as otherwise required or permitted
by this Agreement, between the date of this Agreement and the Closing Date,
Seller shall not, in connection with the conduct of the Business, without the
prior written consent of Buyer:

                  (a) Incur or guaranty any debt relating to the Business in
excess of $50,000 in the aggregate, except accounts payable incurred in the
ordinary course of business;

                  (b) Sell, assign or transfer, or permit the creation of any
Lien (except Permitted Liens) on, any of the Purchased Assets, except any such
assets sold, assigned or transferred in the ordinary course of business
consistent with past practice;

                  (c) Enter into, amend, renew or terminate any Material
Contract or Material Lease relating to the Business, except in the ordinary
course of business, provided that if such Material Contract or Material Lease
relating to the Business would have resulted or may reasonably be expected to

month period following the effective date thereof Buyer's approval thereof shall
be required;


                                       21
<PAGE>

                  (d) Increase the rate of compensation for any Employee, except
for customary merit, bonus, cost-of-living and promotional increases consistent
with past practices of Seller in the conduct of the Business, or promote or hire
any Employee whose annual base salary is or upon such promotion or hiring would
be more than $100,000;

                  (e) Waive any material right, forgive any material debt or
release any claim relating to the Business, except in the ordinary course of
business consistent with past practice;

                  (f) Accelerate or delay the sale of products or services of
the Business or the collection of accounts receivable of the Business, except in
the ordinary course of business consistent with past practice;

                  (g) Make any change in accounting methods or principles or
cost allocation procedures that materially affects the financial statements of
WestComm, except as required by GAAP; or

                  (h) Agree to take any of the actions described in Sections
4.3.2(a) through 4.3.2(g).

            4.3.3 Telecom Contracts. In the event that between the date of this
Agreement and the Closing Date Seller desires to enter into, amend (other than a
price increase for purposes of reducing or eliminating projected losses), renew
or terminate (other than by expiration of its term) any Telecom Contract that
would have resulted or may reasonably be expected to result in the payment or
receipt by the Business of $100,000 or more during any twelve (12) month period
following the effective date thereof, Seller shall provide Buyer with written
notice of such proposed action, including copies of any related documentation.
If, within three (3) business days of receipt of Seller's notice, Buyer approves
such proposed action in writing or fails to deliver to Seller a written
objection to such proposed action, then Buyer shall be deemed to have consented
to the proposed action. If, within such three (3) business day period, Buyer
delivers a written objection to the proposed action, such objection shall be
accompanied by Buyer's written recommendation concerning Seller's proposed
action with respect to such Telecom Contract or proposed Telecom Contract.
Seller, following receipt of Buyer's recommendation, shall not unreasonably
refuse to comply with Buyer's recommendation, provided that Seller shall not be
deemed unreasonable if Buyer's recommendations would require Seller to assume
any liability or obligation not contemplated by Seller's proposed action or
shall result in Seller incurring any losses not contemplated by Seller's
proposed action (other than nominal liability, obligation or loss).

            4.3.4. Buyer's Consent.

                  (a) If Seller gives written notice to Buyer that Seller
proposes to take any action for which Buyer's consent is required under Section
4.3.2 and if Buyer has not delivered to Seller a written objection to such
proposed action within three (3) business days of 


                                       22
<PAGE>

Seller's notice, then Buyer shall be deemed to have consented to such proposed
action. Buyer's consent to any such proposed action shall not be unreasonably
withheld.

                  (b) For purposes of Section 4.3.2 and Section 4.3.3, Buyer
hereby designates Ed Thomas as the person who shall have authority to provide 
any approval to be given thereunder on behalf of Buyer.

            4.3.5 MCI. Following receipt by Seller of the Consent of MCI
Telecommunications Corporation ("MCI") to the transfer and assignment of the MCI
Contract, Buyer and Seller agree to cooperate with each other in order to permit
Buyer to seek to renegotiate the terms of the MCI Contract, effective following
the Closing Date. The renegotiation of the MCI Contract shall not be a condition
to Buyer's obligations hereunder. Seller will, upon Buyer's request, arrange for
meetings between representatives of the Parties and the appropriate
representatives of MCI at times to be reasonably agreed upon by the Parties
(subject to the availability of MCI's representatives). Seller agrees to
commence its efforts to obtain MCI's Consent promptly following the execution of
this Agreement.

            4.3.6 Trademark License. Between the date of this Agreement and the
Closing Date, Seller agrees to review any request of Buyer pursuant to Section
2.4 of the Trademark License Agreement, as if the provisions of Section 2.4 of

approve any such use, such provisions shall be reflected in the Trademark
License Agreement to be executed at Closing. In no event shall Buyer use the
Trade Name or Trademarks for any purpose prior to the Closing Date hereunder.

      4.4. Supplements to Schedules. If between the date hereof and the Closing
Date Seller becomes aware that any of its representations and warranties in this
Agreement was inaccurate when made or if during such period, to Seller's
Knowledge, any event occurs or condition changes that causes any of Seller's
representations and warranties in this Agreement to be inaccurate, then Seller
shall notify Buyer thereof in writing and shall furnish Buyer with a supplement
the schedules hereto to account for any such inaccuracy, event or change. Any
such supplement to the schedules shall be deemed to cure any breach of the
representations and warranties made by Seller in this Agreement unless, within
five (5) business days of receipt thereof (or, if Buyer requests additional
information regarding such inaccuracy, event or change within such five business
day period, then within three (3) business days of receipt of such additional
information, or such additional period of time as may be reasonable in such
circumstances, not to exceed ten (10) business days), Buyer objects to such
supplement and the inaccuracy, event or change therein (together with any other
inaccuracy, event or change previously disclosed in a supplement that Buyer has
not objected to hereunder, on a cumulative basis) has a Material Adverse Effect.

and conduct of the Business.

Encumbered Instruments to which a Consent to transfer and assign must be
obtained from the appropriate third party prior to Closing (the "Required
Consents"). Except for the Required Consents, the obtaining of any Consents
related to the Encumbered Instruments shall not be a condition to Closing, and
Closing shall occur irrespective of whether any such Consent has been obtained.

            6.2.3. Post-Closing Efforts to Obtain Consents. In the event any
Consent necessary to effect the transfer and assignment of any Encumbered
Instrument is not obtained on or prior to Closing (other than a Required
Consent, the receipt of which on or prior to the Closing has not been waived by
Buyer and Seller), each Party will, for a period of one (1) year following the
Closing Date, (a) abide by the requirements of Section 6.2.1 and (b) cooperate
with each other in any lawful and reasonable arrangement to provide that Buyer
shall receive the benefits under any Encumbered Instrument not assigned and
transferred at Closing by reason of the failure to obtain such Consent (a
"Non-Transferred Instrument"), including, if necessary, at the request and
expense (unless any such failure of performance by a third party is due to the
failure to obtain the Consent of such third party to the transfer and assignment
of the Non-Transferred Instrument) of Buyer, enforcing performance by any third
party of its obligations in respect of such Non-Transferred Instrument; provided
that, to the extent the Parties are successful in providing the material
benefits of any Non-Transferred Instrument to Buyer, Buyer shall pay, honor and
discharge when due all Liabilities of Seller related thereto to the extent the
Liabilities were incurred after the Closing Date. Seller shall immediately
transfer and assign to Buyer any Non-Transferred Instrument for which a Consent
has been received, and the Parties shall mutually agree on an appropriate
reconciliation, if any, between them as if the Encumbered Instrument had been an
Assumed Contract on the Closing Date and the current assets and current
liabilities associated with such Assumed Contract had been reflected on the
Statement of Working Capital, as further adjusted after giving effect to all
liabilities (including Liabilities paid pursuant to the preceding sentence) and
benefits received or incurred by either Party relating to such Encumbered
Instrument since the Closing Date (and the Parties shall use reasonable efforts
to agree on an appropriate methodology for calculating such reconciliation prior
to the Closing Date).

            6.2.4. No Assignment. Notwithstanding anything to the contrary in
this Agreement, Seller shall not transfer or assign any interest in any
Encumbered Instrument, and Buyer shall not assume any Liability arising
thereunder or resulting therefrom, if an assignment or transfer or an attempt to
make an assignment or transfer of such Encumbered Instrument without the Consent
of a third party would constitute a breach or violation thereof or a violation
of Law, or affect adversely the rights of Buyer or Seller thereunder, until such
Consent has been obtained.

      6.3. Permits.

            6.3.1. Cooperation and Reasonable Efforts. Each Party hereby agrees
to use reasonable efforts, to take reasonable actions (including Buyer's
delivery to any Governmental Authority of RSL's audited financial statements)
and to cooperate with each other as may be necessary to transfer to Buyer, or
assist Buyer in obtaining, all Permits required to conduct the Business. On or
as soon as practicable after the date hereof, each Party shall file, separately
or jointly with the other Party, as the case may be, all applications necessary
to transfer or obtain the Permits. Each Party shall use reasonable efforts to
resolve such objections, if any, as may be asserted by any Governmental
Authority with respect to the applications contemplated hereby. Buyer shall, if
required by any Governmental Authority, provide or cause RSL to provide the


                                       25
<PAGE>

Governmental Authority with reasonable financial assurances of Buyer's
performance of the obligations associated with a Permit. Buyer shall pay all
filing fees and its own expenses incurred in connection with transferring or
obtaining all Permits.

            6.3.2. Pre-Closing; Required Permits. Schedule 6.3.2 lists the
Communications Licenses, Environmental Permits, and other Permits with respect
to which a Consent must be obtained at or prior to Closing (the "Required
Permits"). Except for the Required Permits, the transfer or issuance to Buyer of
any Permit shall not be a condition to Closing, and Closing shall occur
irrespective of whether any such Permit has been transferred or obtained.

            6.3.3. Post-Closing Efforts to Obtain Permits; Agreement to
Cooperate. (a) In the event any Permit (including any Communications License) is
not obtained on or prior to Closing (other than a Required Permit, the receipt
of which on or prior to the Closing has not been waived by Buyer and Seller),
each Party will, for a period of one (1) year following the Closing Date, (a)
abide by the requirements of Section 6.3.1 and (b) cooperate with each other in
any lawful and reasonable arrangement to provide that Buyer shall receive the
benefits under any Permit not transferred to or obtained by Buyer at Closing (a
"Non-Transferred Permit") or, if not feasible, to permit Seller to retain
temporarily the assets subject to any such Non-Transferred Permit; provided
that, to the extent the Parties are successful in providing the material
benefits of any Non-Transferred Permit to Buyer, Buyer shall pay, honor and
discharge when due all Liabilities of Seller related thereto to the extent the
Liabilities were incurred after the Closing Date. Seller shall immediately
transfer and assign to Buyer any Non-Transferred Permit for which a Consent has
been received.

                  (b) Without limiting the generality of the foregoing, the
Parties agree to use reasonable efforts and to cooperate with each other, in
good faith, (i) in order to arrive, within thirty (30) days after the date of
this Agreement, at a mutually acceptable arrangement to permit Seller to retain
temporarily and/or continue to manage the assets subject to any Non-Transferred
Permit (other than a Required Permit) and (ii) to revise Schedule 6.3.2 to
reduce the number of Required Permits, provided that any such arrangement or
revision shall, in the opinion of counsel of each Party, be lawful under all
Laws governing or relating to the telecommunications, communications or
broadcasting industries and Other Laws and shall not, in the case of such Party,
expose such Party or its Affiliates to any risk of forfeiture, penalty,
revocation, non-renewal or termination with respect to any license or license
application granted or pending under any Laws governing or relating to the
telecommunications, communications or broadcasting industries.

            6.3.4. No Assignment. Notwithstanding anything to the contrary in
this Agreement, Seller shall not transfer or assign any interest in any Permit,
and Buyer shall not assume any Liability arising thereunder or resulting
therefrom, if an assignment or transfer or an attempt to make an assignment or
transfer of such Permit without the Consent of a Governmental Authority would
constitute a breach or violation thereof or a violation of Law, or affect
adversely the rights of Buyer or Seller thereunder, until such Consent has been
obtained.


                                       26

      6.4. Taxes. Following the Closing Date, Seller and Buyer shall provide
each other with such assistance as may reasonably be requested by them in
connection with the preparation of any Tax Return, any Tax audit or other
examination by any Governmental Authority, or any judicial or administrative
proceedings related to liability for Taxes. Seller and Buyer shall retain
(except for books and records delivered by Seller to Buyer pursuant to this
Agreement) and provide each other with any records or information which may be
relevant to such preparation, audit, examination, proceeding or determination.
Such assistance shall include making employees available on a mutually
convenient basis to provide and explain such records and information, and shall
include providing copies of any relevant returns and supporting work schedules.
The Party requesting assistance hereunder shall reimburse the other for
reasonable out-of-pocket expenses incurred in providing such assistance.

      6.5. Books and Records.

            6.5.1. Access. For a period of ten (10) years after Closing, each
Party shall provide the other Party with reasonable access during normal
business hours to its books and records relating to the Business (other than
books and records protected by the attorney-client privilege) to the extent that
they relate to the condition or operation of the Business prior to Closing and
are requested by such Party to prepare its Tax Returns, to respond to Third
Party Claims or for any other legitimate purpose specified in writing. Each
Party shall have the right, at its own expense, to make copies of any such books
and records.

            6.5.2. Destruction. Neither Party shall dispose of or destroy any
books and records relating to the Business to the extent that they relate to the
condition or operation of the Business prior to Closing without first offering
to turn over possession thereof to the other Party by written notice at least
ninety (90) days prior to the proposed date of disposition or destruction.

            6.5.3. Confidentiality. Each Party may take such action as it deems
reasonably appropriate to separate or redact information unrelated to the
Business from documents and other materials requested and made available
pursuant to this Section 6.5 and may condition the other Party's access to
documents and other materials that it deems confidential to the execution and
delivery of an agreement by the other Party not to disclose or misuse such
information.

            6.5.4. Assistance. Each Party shall, upon written request and at the
requesting Party's expense, make personnel available to assist in locating and
obtaining any books and records relating to the Business and make personnel
available whose assistance, participation or testimony is reasonably required in
anticipation of, preparation for or the prosecution or defense of any Third
Party Claim in which the other Party does not have any adverse interest.

      6.6. Supplemental Agreements. At Closing Seller and Buyer shall enter into

to enter into, the following agreements:

the parties to be included therein (including but not limited to medical, dental
and basic life insurance (in each case other than retiree benefits), short-term

received by Seller on account thereof from third parties, including employees,

Article 10, from and after the Closing Date Seller shall indemnify and hold

directors, shareholders and agents (the "Buyer Indemnitees") harmless from and
against any and all Damages suffered by any Buyer Indemnitee arising out of:

            (a) the breach of any representation or warranty made by Seller in

executed and delivered by Seller at Closing pursuant to this Agreement;

            (b) the failure of Seller to perform any covenant or obligation by
Seller contained in this Agreement or in any Operative Document or any other

this Agreement; and

            (c) the failure of Seller to pay and perform any of the Excluded
Liabilities.

      10.2. Indemnification by Buyer. Subject to the other provisions of this
Article 10, from and after the Closing Date Buyer shall indemnify and hold
Seller and its respective employees, representatives, officers, directors,
shareholders and agents (the "Seller Indemnitees") harmless from and against any
Damages suffered by any Seller Indemnitee arising out of:

            (a) the breach of any representation or warranty made by Buyer in

Section 10.1 or Section 10.2 (an "Indemnitee") shall promptly give written
notice to the indemnifying party (the "Indemnitor") after obtaining knowledge of
any claim that it may have pursuant to this Article 10. Such notice shall set
forth in reasonable detail the claim and the basis for indemnification. A
failure to give timely notice as provided in this Section will not affect the
rights or obligations of the Indemnitor or an Indemnitee hereunder except to the
extent that, as a result of such failure to provide timely notice, the
Indemnitor is deprived of its right to recover 


                                       33
<PAGE>

any payment under its applicable insurance coverage or was materially prejudiced
as a result of such failure.

      10.4. Third Party Claims.

            10.4.1. Right to Assume Defense. An Indemnitee shall permit the
Indemnitor to assume and control (at the Indemnitor's sole cost) the defense of
a claim or Action arising from or involving a third party (a "Third Party
Claim") unless (a) the Indemnitor fails to promptly provide to an Indemnitee
written notice of its election to assume defense of the Third Party Claim, (b)
an Indemnitee shall have been advised by counsel that a conflict of interest
exists between the Indemnitee and the Indemnitor with respect to the Third Party
Claim or with respect to any legal defense which may be available (c) the
Indemnitor fails to provide to the Indemnitee reasonable assurance of its
financial capability to defend the Third Party Claim and to provide
indemnification with respect thereto, (d) the Indemnitee, in good faith, objects
to the Indemnitor's choice of counsel, (e) the Indemnitee, in good faith,
believes that the Indemnitor is not diligently conducting the defense of the
Third Party Claim, or (f) the Indemnitor fails to provide a written
acknowledgment of its obligation to indemnify the Indemnitee with respect to the
Third Party Claim. An Indemnitee may participate in the defense or settlement of
a Third Party Claim of which the Indemnitor has assumed the defense, provided
however, that such participation must be conducted through counsel retained at
the Indemnitee's expense.

            10.4.2. Settlement of Third Party Claims. The Indemnitor shall not
consent to entry of any judgment or enter into any settlement without the prior
written consent of the Indemnitee, which consent shall not be unreasonably
withheld, provided however, the Indemnitor may consent to entry of any judgment
or enter into any settlement without the written consent of the Indemnitee so
long as the judgment or settlement includes an unconditional and complete
release of the Indemnitee (without any Liability whatsoever to any Indemnitee)
by the claimant or plaintiff making the Third Party Claim, which release shall
be in a form reasonably satisfactory to the Indemnitee. Alternatively, an
Indemnitee shall not consent to entry of any judgment or enter into any
settlement without the prior written consent of the Indemnitor, which consent
shall not be unreasonably withheld, provided however, an Indemnitee may consent
to entry of any judgment or enter into any settlement without the written
consent of the Indemnitor so long as the judgment or settlement includes an
unconditional and complete release of the Indemnitor (without any Liability
whatsoever to the Indemnitor) by the claimant or plaintiff making the Third
Party Claim, which release shall be in a form reasonably satisfactory to the
Indemnitor. Neither the Indemnitor nor the Indemnitee shall consent to entry of
any judgment or enter into any settlement for non-monetary relief without the
prior written consent of the other, unless such relief does not bind the

indemnify any Indemnitee pursuant to Sections 10.1(a) or 10.2(a) for the breach
of any representation or warranty unless such Indemnitee has in good faith given

the first anniversary of the Closing Date in the case of all representations and
warranties except (a) those representations and warranties set forth in Sections

            10.5.6. Consequential Damages; Mitigation. Neither Party shall have
any obligation to indemnify any Seller Indemnitee or Buyer Indemnitee for (a)
any Consequential Damages or (b) any other Damages that are (i) caused,
contributed to or exacerbated by the actions of any Buyer Indemnitee (in the
case of Seller's indemnification obligations) or any Seller Indemnitee (in the
case of Buyer's indemnification obligations) or by the failure of any Buyer
Indemnitee (in the case of Seller's indemnification obligations) or any Seller
Indemnitee(in the case of Buyer's indemnification obligations) to use all
reasonable efforts to mitigate any such Damages, (ii) recovered or recoverable
by the Indemnitee from any third party (including insurers)


                                       35
<PAGE>

or (iii) offset by tax savings realized on account of such Damages by the
Indemnitee or any of its Affiliates.

            10.5.7. Exclusive Remedy. This Article 10 sets forth the exclusive
remedy for monetary damages owing from Seller to the Buyer Indemnitees and from
Buyer to Seller Indemnitees that arise from the matters described in Sections

for monetary damages that it might assert against the other, with respect to the
matters described in Sections 10.1 and 10.2, whether under common law or under
any Environmental Law or securities, trade regulation or other Law.

      10.6. Indemnity Payments. To the extent permitted by law, all payments
made pursuant to this Article 10 (other than interest payments) shall be treated
by the Parties on all Income Tax Returns as an adjustment to the Purchase Price.

      10.7. Payment and Assignment of Claims.

            10.7.1. Payment. Upon final determination by the Parties or by a
court of competent jurisdiction that a Indemnitee is entitled to indemnification
under this Article 10, the Indemnitor shall promptly pay or reimburse, as
appropriate, the Indemnitee for any Damages to which it is entitled to be
indemnified pursuant to this Agreement. Neither Party shall permit any exercise
of any right of set-off against the other Party until such final determination
is made.

            10.7.2. Assignment. If any of the Damages for which an Indemnitor is
responsible or allegedly responsible under this Article 10 are recoverable or
potentially recoverable against any third party at the time when payment is due
hereunder, the Indemnitee shall assign any and all rights that it may have to
recover such Damages to the Indemnitor or, if such rights are not assignable for
any reason, the Indemnitee hereunder shall attempt in good faith to collect any
and all damages and losses on account thereof from such third party for the
benefit of the Indemnitor.

      10.8. Other Indemnitees. Buyer shall cause the Buyer Indemnitees, and
Seller shall cause the Seller Indemnitees, to comply with the provisions and to
abide by the limitations set forth in this Article 10.

                                   ARTICLE 11
                                EMPLOYEE MATTERS

      11.1. Transfer of Employees.

            11.1.1. Offer of Employment. Buyer shall make a bona fide offer of
employment to each Employee (including all foreign Employees) at the same
location, with the same position and at substantially the same wages and salary
(including bonuses and sales commissions) to that currently received by such
Employee from Seller (a) on the Closing Date to each Employee employed in the
Business who is actively employed by Seller on the Closing Date; and (b) on the
date of the termination of leave of absence, if then available to return to
active employment, to 


                                       36
<PAGE>

each Employee who is listed on Schedule 11.1.1 and who is on workers'
compensation, disability leave, military leave, or other approved leave of
absence on the Closing Date (such date the "Effective Date") (such Employees who
become employees with Buyer, the "New Employees"), provided that nothing herein
shall require Buyer to employ any New Employee other than on an at-will basis.
Except with respect to benefits provided under the Transitional Services
Agreement during the term thereof, all New Employees shall be entitled to
participate in Buyer's benefit plans and policies on the same basis and subject
to the same qualifications as other similarly situated employees of Buyer
(giving credit to the New Employees for time of service with Seller as provided
in Section 11.2.2 below), for a period of at least one year after the Effective
Date (so long as such Employee continues to be in the employ of Buyer).

            11.1.2. Foreign Employment Matters. (a) Without limiting the
generality of Section 11.1.1, Buyer (or its appropriate foreign affiliate) shall
make a bona fide offer of employment complying with Section 11.1.1 to each
Employee who is employed outside the United States (the "Foreign Employees"). If
either as a result of any Foreign Employee's non-acceptance of such offer of
employment, or as a result of Buyer's failure, effective as of the Closing Date,
to establish and qualify or register with applicable regulatory authorities
employee benefit plans for, or to extend existing Buyer employee benefit plans,
programs, policies and arrangements to, the Foreign Employees which are in
accordance with local Law and which provide benefits to the Foreign Employees on
terms and conditions which are substantially similar in the aggregate to those
provided to Foreign Employees by Seller or its Affiliates immediately prior to
the Closing Date, such Foreign Employees shall be entitled to receive any
severance, redundancy, termination, payment in lieu of notice, indemnity or
other payments, then whichever of Seller or Buyer shall be responsible for such
liability under local Law shall be responsible for and pay such liability.
Notwithstanding the foregoing, if any Foreign Employee situated in Belgium
shall, prior to the Closing Date, provide a written notice of resignation to
Seller, then Buyer shall not be liable for any such severance or other payments
to such Foreign Employee.

            (b) Except as otherwise specifically provided in this Section
11.1.2, effective as of the Closing Date, each Foreign Employee who is an active
participant in any foreign pension plan shall cease to be an active participant
thereunder.

            (c) Notwithstanding the foregoing provisions of this Section 11.1.2,
Foreign Employees whose employment by Buyer will be delayed beyond the Closing
Date due to applicable foreign law (including, without limitation, due to the
requirement that Buyer establish separate legal entities as employer) ("Delayed
Foreign Employees") will continue on a payroll of Seller or its Affiliates and
will continue to participate in each of Seller's or its Affiliates' employee
benefit plans in which they are participating immediately prior to the Closing
Date until the applicable date on which they first become eligible to become
employed by Buyer (the "Delayed Transfer Date"). Buyer will offer employment on
the applicable Delayed Transfer Date to each such Delayed Foreign Employee then
in employment, and on and as of the applicable Delayed Transfer Date, each such
Delayed Foreign Employee then in employment will become a New Employee for all
purposes of this Agreement. Buyer will promptly reimburse Seller for 100% of the
payroll, benefits (including statutory benefits, severance and other termination
benefits) and other costs and expenses directly or indirectly relating to
Delayed Foreign Employees consistent 


                                       37
<PAGE>

with past practice within 15 days following receipt of each written notification
(including reasonable substantiation of costs and expenses) from Seller or any
of its Affiliates of such payroll, benefits and other costs and expenses. All
services rendered by such Delayed Foreign Employees after the Closing Date shall
be for the benefit of the Business.

            11.1.3. WARN Act. Provided Buyer fully complies with its obligations
under Section 11.1.1, Seller shall be responsible for any compliance that may be
required solely as a result of the consummation of the transactions contemplated
by this Agreement with all applicable provisions of the Worker Adjustment and
Retraining Notification Act of 1988 (the "WARN Act") and any similar state or
local Law. Except as provided in the previous sentence, Buyer shall be
responsible for compliance that may be required on or after the Closing Date
with all applicable provisions of the WARN Act and any similar state or local
Law.

      11.2. Employee Benefit Plans.

            11.2.1. Coverage Under Employee Benefit Plans. Except as otherwise
specifically provided in this Section 11.2, effective as of the Effective Date,
each New Employee who is an active participant in Seller's Employee Benefit
Plans shall cease to be an active participant, and all of such New Employees
shall become immediately eligible to participate in each of Buyer's Employee
Benefit Plans (subject to Section 11.1.2(c)).

            11.2.2. Recognition of Service. Seller shall retain all assets and
liabilities under Seller's Pension Plan attributable to service prior to the
Closing Date for each New Employee who is a participant in Seller's Pension Plan
immediately prior to the Closing Date and is employed by Buyer on the Closing
Date as provided in Section 11.1. Buyer shall grant to each New Employee credit
for his service with Seller prior to the Closing Date (based on the information
provided to Buyer by Seller) for the purpose of eligibility and vesting under
any Buyer Employee Benefit Plan.

            11.2.3. Seller's Savings Program.

            (a) If Buyer agrees to a trust-to-trust transfer, Seller shall cause
the account balances of the New Employees who are participants in Seller's
Savings Program to be fully vested and nonforfeitable as of the date of the
transfer of assets.

            (b) On the Effective Date, or as soon thereafter as practicable,
Seller shall transfer and Buyer shall accept cash and promissory notes
evidencing outstanding loans to the New Employees and account balances equal in
amount to the assets received of Seller's Savings Program attributable to the
New Employees (including assets and account balances of any "alternate payee,"
as such term is defined in section 414(p)(8) of the Code, with respect to any
New Employee). As of the Effective Date, Seller shall not accept from any New
Employees any pre-tax or after-tax contributions to Seller's Savings Program. To
receive such transfer, Buyer shall adopt a defined contribution plan or shall
use an existing defined contribution plan (the "Buyer's Savings Plan").


                                       38
<PAGE>

            (c) As soon as practicable after the Effective Date, Seller shall
cause the Master Trust (as such term is defined in the Seller's Savings Program)
to transfer the assets set forth above and full account balances of the New
Employees to the trust under the Buyer's Savings Plan (the "Buyer's Savings Plan
Trust") and the Buyer's Savings Plan Trust shall accept such transfer. Pursuant
to ERISA and other applicable law, immediately after the transfer of assets and
account balances, each New Employee shall be entitled to receive an account
balance from Buyer's Savings Plan that is at least equal to the account balance
such New Employee would have been entitled to receive from Seller's Savings
Program immediately prior to such transfer but only to the extent that Buyer's
Savings Plan Trust shall receive assets equivalent to such account balances and
the New Employees shall only be eligible to receive benefits from Buyer's
Savings Plan. The account balances of the New Employees under Seller's Savings
Program shall be reduced by any withdrawal, distribution or necessary benefit
payments in respect to New Employees occurring during the period from the
Effective Date to the date of transfer to Buyer's Savings Plan as described
herein. In the event any New Employee has a loan outstanding in Seller's Savings
Program at the time of transfer, all loan documentation concerning such loan
shall be assigned to Buyer's Savings Plan. All New Employee payments after the
Effective Date shall be made to Buyer's Savings Plan.

            11.2.4. To facilitate the proper and orderly transfer of assets to
Buyer's Savings Plan as contemplated by Section 11.2.3, Buyer shall provide
Seller with either (i) no later than 30 days after the Closing Date, an opinion
of counsel (including internal corporate counsel) representing that the new plan
will, upon review of the Internal Revenue Service, be determined to satisfy the
requirement of Code Sections 401(a) and 501(a), if Buyer establishes a new plan,
or such other corrective action as requested by the Internal Revenue Service
will be taken to qualify Buyer's Savings Plan, or (ii) a copy of the most recent
Internal Revenue Service favorable determination letter with respect to Buyer's
Savings Plan and an opinion of counsel (including internal corporate counsel)
representing that there have been no amendments, changes, actions or other
events since the issuance of such favorable determination letter which would
adversely affect such plan's qualification. Each of the Parties shall be
responsible for its respective governmental filings, including Internal Revenue
Service Form 5310A, if applicable. Seller shall provide Buyer with a copy of the
most recent Internal Revenue Service favorable determination letter with respect
to the Westinghouse Savings Program and an opinion of counsel (including
internal corporate counsel) representing that there have been no amendments,
changes, actions or other events since the issuance of such favorable
determination letter which would adversely affect such plan's qualification.

            11.2.5. Welfare and Fringe Benefit Plans. Buyer shall grant to each
New Employee credit for his service with Seller prior to the Effective Date
(based on information provided to Buyer by Seller) under Buyer's Welfare Benefit
Plans and shall grant credit for deductibles and co-payments previously paid.
Buyer's Welfare Benefit Plans shall not exclude from coverage any pre-existing
condition of any of the New Employees. Except with respect to benefits provided
under the Transitional Services Agreement during the term thereof, Buyer shall
grant immediate eligibility for participation in all Buyer's Welfare Benefit
Plans to all New Employees. Any valid claims of any New Employee made against a
Buyer's Welfare Benefit Plan incurred prior to the Effective Date shall be
satisfied by Seller under Seller's Welfare Benefit


                                       39
<PAGE>

Plans, and, to the extent not paid from such employee's contributions,
reimbursed by Buyer. Any claims for hospitalization or other confinement charges
with respect to any hospitalization or other confinement of a New Employee or
eligible dependent that commences prior to the Effective Date in accordance with
the terms and provisions of Seller's plans and policies shall be satisfied by
Seller under Seller's Welfare Benefit Plans, and, to the extent not paid from
such employee's contributions, reimbursed by Buyer. Buyer shall be responsible
for payment of all benefits payable to the New Employees incurred on or after
the Effective Date, whether pursuant to the Transitional Services Agreement or
otherwise. For purposes of this Section 11.2.5, an expense shall be deemed
incurred when the Welfare Benefit Plans service relating to the expense is
provided (regardless of when the incident giving rise to the expense occurs).
