                                     PART I

ITEM 1. BUSINESS
(In thousands of dollars except per share data)

  Unless the context otherwise requires, references to 1998, 1997 and 1996 are
references to the Corporation's fiscal years ended November 30, 1998, 1997 and
1996, respectively.

I.  GENERAL

  The Corporation is an international provider of a broad range of design,
engineering, construction, construction management, facilities management,
environmental remediation and mining services to diverse public and private
sector clients. Through its various operating units, the Corporation:

  .  Provides design, construction and renovation services for plants and
     facilities in the general manufacturing, chemical, petrochemical, food and
     beverage, pharmaceuticals, high-technology and institutional buildings
     markets;

  .  Provides a full range of engineering and construction services to power
     generation utilities, including construction of new plants, retrofitting of
     existing plants and decommissioning and decontamination of nuclear plants
     that have reached the end of their operating lives;

  .  Provides total facilities management to industrial clients, including
     maintenance, engineering and construction, and operations and logistics
     management at manufacturing plants and related facilities and at toll
     roads;

  .  Provides facilities management and environmental remediation services to
     governmental agencies, such as the Department of Energy and the Department
     of Defense;

  .  Provides design, engineering, construction and construction management
     services for infrastructure projects in the transportation, marine and
     water resources markets, including highway, bridge, railroad, airport,
     marine port and water distribution and storage facilities projects; and

  .  Provides contract mining services in the fossil fuel and industrial
     minerals markets, together with technical and engineering services such as
     resource evaluation, geologic modeling, mine planning and development,
     equipment selection and remediation.

                                      I-1
<PAGE>
 
  In providing  its services, the Corporation enters into three basic types of
contracts:

  .  Fixed-price or lump-sum contracts providing for a  fixed price for the
     total amount of work to be performed;

  .  Unit-price contracts providing for a fixed price for each unit of work
     performed; and

  .  Cost-type contracts providing for reimbursement of costs plus a fee.

  Both anticipated income and economic risk are greater under fixed-price and
unit-price contracts than under cost-type contracts. Engineering, construction
management and environmental and hazardous substance remediation contracts are
typically awarded on a cost-plus-fee basis. See "Risk Factors - The
Corporation's fixed-price and unit-price contracts place the risk of increased
project costs on the Corporation."

  The Corporation also participates often as sponsor and manager in construction
joint ventures that are formed for the purpose of bidding, negotiating and
completing specific projects. In addition, the Corporation participates in the
following mining ventures: Westmoreland Resources, Inc., a coal mining company
in Montana, and MIBRAG mbH, a company that operates lignite coal mines and power
plants in Germany. See Note 6. "Ventures" of Notes to Consolidated Financial
Statements in Part II of this Annual Report on Form 10-K .

  The Corporation was originally formed in Delaware on April 28, 1993 under the
name Kasler Holding Company to become the parent company of WCG Holdings, Inc.
("WCG") and Kasler Corporation ("Kasler"),  which were active in the
infrastructure, contract mining, environmental remediation, commercial
construction and construction materials markets. In April 1996, the name of the
Corporation was changed from Kasler Holding Company to Washington Construction
Group, Inc.

  On September 11, 1996, the Corporation acquired the net assets and the
engineering and construction operations of Morrison Knudsen Corporation, a
Delaware corporation ("Old MK"), in a transaction structured as a merger of Old
MK with and into the Corporation, and changed its name to Morrison Knudsen
Corporation. The acquisition of Old MK was an integral part of the
reorganization of Old MK pursuant to a plan of reorganization (the "Plan") filed
by Old MK in the United States Bankruptcy Court for the District of Delaware
(the "Bankruptcy Court").  The Plan was confirmed by the Bankruptcy Court on
August 26, 1996, and became effective concurrently with the merger on September
11, 1996. The Corporation has no remaining obligations under the Plan.

   The Corporation's executive offices are located at Morrison Knudsen Plaza,
Boise, Idaho 83729, and its telephone number is (208) 386-5000.

II.  OPERATING UNITS

  The  Corporation's operations have been conducted through three market-driven
operating units: The Engineers and Constructors Group based in Cleveland, Ohio,
and the Heavy Civil Construction Group and the Mining Group based in Boise,
Idaho. In January 1999, the Corporation announced the consolidation of the Heavy
Civil Construction Group and the Mining Group into "Morrison Knudsen Contractors
Group."

ENGINEERS AND CONSTRUCTORS GROUP:

  The Engineers and Constructors Group, which is the largest and most diverse of
the Corporation's operating groups, is comprised of five divisions:

  . Industrial/Process Division: This division primarily targets Fortune 100
    clients and provides design and construction services for new construction
    or renovations of plants and facilities in the general manufacturing,
    chemical, petrochemical, food and beverage, pharmaceuticals, high-technology
    and institutional-buildings markets.

                                      I-2
<PAGE>
 
  .  Energy Division: This division offers a full range of engineering and
     construction services to power generation utilities. These services include
     construction of power plants, installation of flue-gas scrubber systems and
     plant retrofit projects such as the replacement of steam generators in
     nuclear power plants, a division specialty. This division also provides
     decommissioning and decontamination of nuclear power plants that have
     reached the end of their operating lives.

  .  Operating and Maintenance Division: This division primarily provides total
     facilities management services to industrial clients. These services
     include maintenance, engineering and construction and operations and
     logistics management at manufacturing plants and related facilities and at
     toll roads. These services are typically outsourced by firms that want to
     focus internal resources on plant production.

  .  Transportation Division: This division, which operates as "MK Centennial
     Engineering," specializes in engineering and construction management of
     highway, bridge, railroad, airport and water resource infrastructure
     projects.

  .  Federal Programs Division: This division specializes in the operation and
     environmental remediation of government facilities, primarily for the
     Department of Energy and the Department of Defense .

The Engineers and Constructors Group also performs private sector environmental
remediation work, builds and operates chemical weapons demilitarization
facilities and constructs infrastructure projects internationally.

HEAVY CIVIL CONSTRUCTION GROUP:

  The Heavy Civil Construction Group, which is one of the largest organizations
of its kind in the United States, provides services both as a general contractor
and in a design-build capacity.  This group targets infrastructure projects in
the transportation, marine and water resources markets. This group also provides
site development at mine, industrial, commercial, recreational and large
residential sites.

MINING GROUP:

  The Mining Group is an international provider of contract mining services  for
the fossil fuel and industrial minerals markets. In addition,  this group offers
a full range of technical and engineering services, including resource
evaluation, geologic modeling, mine planning and development, environmental
permitting, equipment selection and remediation.

III.  GOVERNMENT CONTRACTS AND BACKLOG

  Government contracts are a significant part of the Corporation's business. See
"Risk Factors - The government can audit and potentially disallow claims for
compensation under the Corporation's government contracts, and can terminate
such contracts without cause."

  Backlog consists of uncompleted portions of engineering and construction
contracts, including the Corporation's proportionate share of construction
joint-venture contracts and its share of revenues from mining service contracts
and ventures for the next five years. Backlog of all uncompleted contracts at
November 30, 1998 totaled $2.7 billion compared with November 30, 1997 backlog
of $3.7 billion as originally reported and $2.8 billion as restated. (See the
following paragraph for a description of the principal reasons for this decrease
in backlog.) Approximately $657 million or 25% of the backlog at November 30,
1998 was comprised of U.S. government contracts which are subject to termination
by the government, $402 million of which had not been funded. Terminations for
convenience of the government generally provide for recovery of contract costs
and related earnings. Approximately $1.2 billion or 44% of 1998 year-end backlog
is expected to be recognized as revenue in 1999.

  Although backlog reflects business which is considered to be firm,
cancellations or scope adjustments may occur. Backlog has been adjusted to
reflect known project cancellations, deferrals and revisions in project scope
and cost, both 

                                      I-3
<PAGE>
 
upward and downward. In the third quarter of 1998, the Corporation reduced
backlog by approximately $102 million reflecting the reduction in scope of an
environmental contract for the U.S. government. In anticipation of its pending
acquisition of certain businesses presently owned and operated by CBS
Corporation (see Note 14. "Acquisition of Westinghouse Businesses" of Notes to
Consolidated Financial Statements) which are engaged in the performance of
significant government contracts, and to reduce the exposure to material
adjustments due to scope and funding issues on other government contracts
included in reported backlog, the Corporation made an assessment of its policy
of including in backlog unfunded U.S. government contracts. During the fourth
quarter of 1998, the Corporation adopted a new policy which excludes from
backlog unfunded government contracts which management is not highly confident
will be funded within two years. Backlog has been reduced by $843 million in the
fourth quarter, primarily as a result of the adoption of this new policy. The
reduction in backlog is not an impairment of the revenues or earnings potential
of the Corporation. However, there can be no assurance that future contract
cancellations or modifications will not reduce backlog and future revenues.

</TABLE>

*Amounts have been restated to conform with the adoption of the new policy in
1998. The Corporation typically has, at any given point in time, 25% to 35%
additional unreported backlog representing awarded yet unfunded contracts and
any mining business beyond five years.

IV.  EMPLOYEES

  The Corporation's total worldwide employment varies widely with the volume,
type and scope of operations under way at any given time and other factors.

  At November 30, 1998, the Corporation employed a total of approximately 9,000
employees -- including 5,800 salaried and project direct-hire craft employees
and 3,200 employees covered by collective bargaining agreements.

V.  RAW MATERIALS

  Raw materials and components necessary for the rendering of construction,
environmental and hazardous substance remediation and contract mining services
are generally available from numerous sources. The Corporation does not foresee
any unavailability of raw materials and components which would have a material
adverse effect on its business in the near term.

VI.  COMPETITION

  Engineering and construction is a highly competitive business, particularly
for contracts obtained by competitive bidding. The Corporation competes based
primarily on price, reputation and reliability with other general and specialty
contractors, both foreign and domestic. Success or failure in the engineering
and construction industry is, in large measure, based upon the ability to
compete successfully for contracts and to provide the engineering, planning,
procurement, management and project financing skills required to complete them
in a timely and cost-efficient manner. See "Risk Factors - The Corporation is
engaged in highly competitive businesses and must bid against competitors to
obtain engineering, construction and service contracts."

                                      I-4
<PAGE>
 
VII.  ENVIRONMENTAL MATTERS

  The Corporation's environmental and hazardous substance remediation and
contract mining services involve risks of liability under federal, state and
local environmental laws and regulations, including the Comprehensive
Environmental Response, Compensation, and Liability Act ("CERCLA"). The
Corporation performs environmental remediation at Superfund sites as a response
action contractor for the Environmental Protection Agency (the "EPA") and, in
such capacity, is exempt from liability under any federal law, including CERCLA,
unless its conduct was negligent; moreover, the Corporation may be entitled to
indemnification from the United States against liability arising out of
negligent performance of work in such capacity. A determination that the
Corporation is liable under environmental laws and regulations for the cost of
environmental remediation due to its performance of contract mining or
environmental remediation could have a material adverse effect on the financial
position, results of operations and cash flows of the Corporation. Amendments
to, or more stringent implementation of, current environmental laws and
regulations also could have such adverse effects.

  For additional information regarding environmental matters, see "Summitville
environmental matters" and "Other environmental matters" in Note 13.
"Contingencies and Commitments" of Notes to Consolidated Financial Statements.
See also "Risk Factors - The Corporation could be subject to liability under
environmental laws."

VIII.  RISK FACTORS

  The Corporation and its businesses are subject to a number of risks, including
those enumerated below. Any or all of such risks could have a material adverse
effect on the business, financial condition, results of operations and cash
flows of the Corporation and on the market price for the Corporation's
securities. See also "Note Regarding Forward-Looking Information."

THE CORPORATION IS ENGAGED IN HIGHLY COMPETITIVE BUSINESSES AND MUST BID AGAINST
COMPETITORS TO OBTAIN ENGINEERING, CONSTRUCTION AND SERVICE CONTRACTS:

  The Corporation is engaged in highly competitive businesses, particularly
those portions relating to engineering, construction and other service contracts
that are awarded through competitive bidding processes. The Corporation competes
with other general and specialty contractors, both foreign and domestic,
including large international contractors and small local contractors. Certain
competitors have greater financial and other resources than the Corporation
which, in some instances, could give them a competitive advantage over the
Corporation.

ECONOMIC DOWNTURNS AND REDUCTIONS IN GOVERNMENT FUNDING COULD HAVE A NEGATIVE
IMPACT ON THE CORPORATION'S BUSINESSES:

  Demand for the services offered by the Corporation has been, and is expected
to continue to be, subject to significant fluctuations due to a variety of
factors beyond its control, including economic conditions.  During economic
downturns, the ability of both private and governmental entities in targeted
markets to make capital expenditures on infrastructure improvement may decline
significantly. There can be no assurance that economic or political conditions
generally will be favorable or that there will not be significant fluctuations
adversely affecting the industry as a whole or key markets targeted by the
Corporation. In addition, the Corporation's operations are in part dependent
upon governmental funding of infrastructure and environmental projects.
Significant changes in the level of government funding of these projects could
have an unfavorable impact on the operating results of the Corporation.

THE CORPORATION'S FIXED-PRICE AND UNIT-PRICE CONTRACTS PLACE THE RISK OF
INCREASED PROJECT COSTS ON THE CORPORATION:

  The Corporation's fixed-price and unit-price contracts involve risks relating
to the inability of the Corporation to receive additional compensation in the
event that the costs of performing such contracts prove to be greater than
anticipated. The Corporation's cost of performing such contracts may be greater
than anticipated due to uncertainties inherent in estimating contract completion
costs, contract modifications by customers, failure of subcontractors and 

                                      I-5
<PAGE>
 
joint-venture partners to perform and other unforseen events and conditions. Any
one or more of these risks could result in reduced profits or increase losses on
a particular contract or contracts.

THE GOVERNMENT CAN AUDIT AND POTENTIALLY DISALLOW CLAIMS FOR COMPENSATION UNDER
THE CORPORATION'S GOVERNMENT CONTRACTS, AND CAN TERMINATE SUCH CONTRACTS WITHOUT
CAUSE:

  Government contracts are a significant part of the Corporation's business. In
addition to other significant government contracts, contracts and subcontracts
with the United States Department of Energy accounted for approximately 14% of
the Corporation's revenues for the year ended November 30, 1998. See Note 12.
"Geographic and Customer Information" of Notes to Consolidated Financial
Statements. The Corporation has a number of cost reimbursement contracts with
various agencies of the U.S. government. Allowable costs under these contracts
are subject to audit by the U.S. government. To the extent that such audits
result in determinations that costs claimed as reimbursable are not allowable
costs or were not allocated in accordance with federal government regulations,
the Corporation could be required to reimburse the U.S. government for amounts
previously paid. See "Government Contracts and Backlog" for the relative
significance of U.S. government contracts included in year-end 1998 backlog and
related risks. See Note 13.  "Contingencies and Commitments -- Contract related
matters" of Notes to Consolidated Financial Statements.

  The Corporation has a number of contracts and subcontracts with various
agencies of the U.S. government, principally for environmental remediation and
restoration work, which extend beyond one year and for which government funding
has not yet been approved. There can be no assurance that such funding will be
approved. All contracts with agencies of the U.S. government and some commercial
and foreign contracts are subject to unilateral termination at the option of the
customer.  In the event of a termination, the Corporation would not receive
projected revenues or profits associated with the terminated portion of such
contracts.

THE CORPORATION'S BUSINESSES INVOLVE MANY PROJECT-RELATED AND CONTRACT-RELATED
RISKS:

  The engineering and construction business is subject to a variety of project-
related risks, including changes in political and other circumstances,
particularly since contracts for major projects are performed over extended
periods of time. These risks include the failure of applicable governing
authorities to take certain necessary actions, opposition by third parties to
particular projects and the failure to obtain adequate financing for particular
projects. Due to these factors, losses on a particular contract or contracts
could occur, and the Corporation could experience significant changes in
operating results on a quarterly or annual basis.

  Because of the size and complexity of major infrastructure projects, a
relatively small number of projects may provide a significant percentage of the
Corporation's revenue in a given year. The loss of one or more major contracts
or the inability of the Corporation to perform profitably under one or more
major contracts, could have a material adverse effect on the Corporation's
financial condition, results of operations and cash flows.

  The Corporation may also be adversely affected by various risks and hazards,
including industrial accidents, labor disputes, geological conditions,
environmental hazards, weather and other natural phenomena such as earthquakes
and floods.

THE CORPORATION'S SUCCESS DEPENDS ON ATTRACTING AND RETAINING QUALIFIED
PERSONNEL IN A COMPETITIVE ENVIRONMENT:

  The Corporation is dependent upon its ability to attract and retain highly
qualified managerial, technical and business development personnel. Competition
for such personnel is intense. There can be no assurance that the Corporation
can retain its key managerial, technical and business development personnel or
that it can attract, assimilate or retain such personnel in the future.

THE CORPORATION'S INTERNATIONAL OPERATIONS INVOLVE SPECIAL RISKS:

  The Corporation pursues project opportunities throughout the world through
foreign and domestic subsidiaries as well as agreements with foreign joint-
venture partners. These foreign operations are subject to special risks,
including:

  .  Uncertain political and economic environments,

  .  Potential incompatibility with foreign joint-venture partners,

  .  Foreign currency controls and fluctuations,

  .  Civil disturbances, and

  .  Labor strikes.

  Events outside of the Corporation's control may limit or disrupt operations,
restrict the movement of funds, result in deprivation of contract rights,
increase foreign taxation or limit repatriation of earnings.  In addition, in
certain cases applicable law and joint-venture or other agreements may provide
that each joint-venture partner is jointly and severally liable for all
liabilities of the venture. See Note 12. "Geographic and Customer Information"
of Notes to Consolidated Financial Statements.

THE CORPORATION COULD BE SUBJECT TO LIABILITY UNDER ENVIRONMENTAL LAWS:

  The Corporation is subject to a variety of environmental laws and regulations
governing, among other things, discharges to air and water, the handling,
storage, and disposal of hazardous or solid waste materials and the remediation
of contamination associated with releases of hazardous substances.  Such laws
and regulations and the risk of attendant litigation can cause significant
delays to a project and add significantly to its cost. Violations of these
environmental laws and regulations could subject the Corporation and its
management to civil and criminal penalties and other liabilities. There can be
no assurance that such laws and regulations will not become more stringent, or
more stringently implemented, in the future.

  Various federal, state and local environmental laws and regulations, as well
as common law, may impose liability for property damage and costs of
investigation and cleanup of hazardous or toxic substances on property currently
or previously owned by the Corporation or arising out of the Corporation's waste
management activities.  Such laws may impose responsibility and liability
without regard to knowledge of or causation of the presence of the contaminants,
and the liability under such laws is joint and several.  The Corporation has
potential liabilities associated with its past waste management and contract
mining activities and with its current and prior ownership of certain property.
See "Business -- Environmental Matters" and "Other environmental matters" in
Note 13. "Contingencies and Commitments" of Notes to Consolidated Financial
Statements.
 
THE FAILURE OF THE CORPORATION OR ITS BUSINESS PARTNERS TO BE YEAR 2000
COMPLIANT COULD HAVE ADVERSE CONSEQUENCES:

  Like most other companies and organizations, the Corporation relies on
computer-based technology in the conduct of its business. The Corporation has
been and is continuing to address the impact of the  "Year 2000" issue. This
issue is the result of computer programs that were written using two digits
rather than four to define calendar years. These programs may fail to properly
differentiate between calendar years in the twenty-first century and calendar
years in the twentieth century (e.g., they may recognize a date using "00" as
the year 1900 rather than the year 2000). If not corrected, the Year 2000 issue
could result in complete system failures or miscalculations causing significant
disruption of normal business activities.

                                      I-7
<PAGE>
 
  The Corporation has been and is continuing to assess and resolve Year 2000
issues associated with its material internal systems and its material third-
party relationships. Although the Corporation believes that its Year 2000
readiness efforts are designed to appropriately identify and address those Year
2000 issues that are within the Corporation's control, there can be no assurance
that the Corporation's efforts will be fully effective. The newness and
complexity of the issues presented and the Corporation's dependence on the
technical skills and preparedness of third parties are among the factors that
could cause the Corporation's efforts to be less than fully effective. Moreover,
Year 2000 issues present many risks that are simply beyond the Corporation's
control, such as the potential effects of Year 2000 issues on the economy in
general and on the Corporation's business partners, vendors, subcontractors and
customers in particular. See "The Year 2000 Issue" in Item 7. "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

ONE SHAREHOLDER'S LARGE OWNERSHIP INTEREST IN THE CORPORATION, PROVISIONS OF
DELAWARE LAW AND THE CORPORATION'S ORGANIZATIONAL DOCUMENTS COULD INHIBIT A
TAKEOVER OF THE CORPORATION:

  As of November 30, 1998, Dennis R. Washington, the Chairman of the Board of
Directors of the Corporation, beneficially owned 37.88% of the 53,352,410 shares
of outstanding common stock of the Corporation. As of February 3, 1999, Mr.
Washington is also President and Chief Executive Officer of the Corporation. Mr.
Washington's substantial ownership interest and certain provisions of the
Delaware General Corporation Law, the Corporation's Certificate of Incorporation
and Bylaws and certain agreements to which the Corporation is a party, may have
the effect of delaying, deterring or preventing a change in control of the
Corporation. In addition, the Certificate of Incorporation authorizes the
issuance of up to 100,000,000 shares of common stock and 10,000,000 shares of
preferred stock of the Corporation. The Board of Directors has the power to
determine the price and terms under which any such additional capital stock may
be issued and to fix the terms of such preferred stock, and existing
stockholders of the Corporation will not have preemptive rights with respect
thereto.

ITEM 2.  PROPERTIES
(In thousands of dollars)

  At November 30, 1998, the Corporation owned more than 3,500 units of heavy and
light mobile construction, environmental remediation and contract mining
equipment.

  The Corporation does not own significant real property for operations other
than certain land and improvements in Highland and Petaluma, California. At
November 30, 1998, the Corporation had real estate held for sale in  Nevada. The
two principal administrative office facilities in Boise, Idaho, and Cleveland,
Ohio, of approximately 214,700 square feet and 246,700 square feet,
respectively, are leased under long-term, noncancelable leases expiring in 2003
and 2010, respectively. The Corporation's long-term aggregate rental obligations
for the Boise and Cleveland facilities under these noncancelable leases for each
of the next five years approximate $6,970, $6,970, $7,495, $7,545 and $6,911,
respectively.

  Annual rental payments  for real estate and equipment leased by the
Corporation during the year ended November 30, 1998 aggregated $52,067. See Note
13. "Contingencies and Commitments -- Long-term leases" of Notes to Consolidated
Financial Statements.

  Construction, environmental remediation and mining equipment and leased
administrative and engineering facilities are considered by the Corporation to
be well maintained and suitable for current operations.

- -----------------------------------------------------------------------------
</TABLE>
REVENUE AND GROSS PROFIT:

  Revenue for the fourth quarter and year ended November 30, 1998 increased
$104.0 million to $543.3 million and $184.9 million to $1,862.2, respectively,
compared to $439.3 million and $1,677.3 million for the comparable periods in
1997. These increases were principally due to an increase in the volume of
industrial/process, operation and maintenance and energy  project work executed
by the Engineers and Constructors Group. Revenue increased slightly for the
fourth quarter and year ended November 30, 1998 in the Heavy Civil Construction
Group and for the fourth quarter in the Mining Group over the comparable periods
in 1997. The increase in the Corporation's  revenue for the year ended November
30, 1998 was partially offset by a decrease in revenue from the Mining Group,
which experienced a lower demand for coal production and power generation from
the MIBRAG mbH mining venture in Germany during the first nine months of 1998
and the completion of a significant long-term mining contract in the third
quarter of 1997. MIBRAG mbH increased coal production in the fourth quarter of
1998 over each of the previous three quarters of the year.

  Gross profit for the fourth quarter and year ended November 30, 1998 increased
$2.8 million to $24.1 million and $7.2 million to $86.5 million, respectively,
compared to $21.3 million and $79.3 million for the comparable periods of 1997.
Gross profit for the fourth quarter of 1998 included favorable results from each
of the Corporation's operating groups. During the fourth quarter of 1997, the
Corporation recognized a $3.9 million pretax loss on a large, fixed-price joint-
venture contract. Gross profit for the year ended November 30, 1998 included
improved profitability in the Heavy Civil Construction Group and a $5.7 million
settlement on an environmental contract. These increases were partially offset
by lower demand for coal production and power generation from the MIBRAG mbH
mining venture during the first nine months of the year, the recognition of a
loss related to start up difficulties on a fixed-price construction contract and
$5.4 million net losses related to the write-off of investment in a solvent
extraction facility and a related contract to treat contaminated soil. Gross
profit for the year ended November 30, 1997 included earnings from a significant
long-term mining contract completed in the third quarter of 1997, offset by
provisions for losses at completion for contracts in progress of $9.5 million
and a $3.9 million pretax loss on a large, fixed-price joint-venture contract.

  Gross profit as a percentage of revenue for the fourth quarter and year ended
November 30, 1998 was 4.4% and 4.6%, respectively, compared to 4.8% and 4.7% for
the same periods in 1997. The decrease in gross profit percentage in 1998 was
primarily due to a higher proportion of revenue attributable to the Engineers
and Constructors Group, 

                                      II-3
<PAGE>
 
which had lower operating margins than the comparable period of 1997. The
Engineers and Constructors Group typically executes cost-plus contracts which
have less risk but lower margins. Gross profit percentage for the fourth quarter
of 1998 increased slightly from 4.3% for the third quarter of 1998.

  The Corporation's operating margins often vary between periods due to inherent
risks and rewards on fixed-price contracts causing unexpected gains and losses
on contracts. Operating margins may also vary between periods due to changes in
the mix and timing of contracts executed by the Corporation, which contain
various risk and profit profiles and uncertainties inherent in the estimation
process. The Corporation strives to offset certain of the risks inherent in its
contracts through geographic, customer and risk diversification.

  At November 30, 1998, backlog of $2,680 million was comprised of $901 million
(34%) of revenue from fee-type contracts and $1,779 million (66%) of revenue
from fixed-price contracts and the Corporation's share of revenue from mining
ventures.

GENERAL AND ADMINISTRATIVE EXPENSES:

  General and administrative expenses for the fourth quarter and year ended
November 30, 1998 increased $.5 million and $1.3 million, respectively, compared
to the comparable periods of 1997. The increase is attributable to an increase
in implementation costs of new computer information systems for financial, human
resource and payroll  functions and the reengineering of the Corporation's
financial processes. The Corporation's implementation costs are anticipated to
continue through 1999. The Corporation expects the system implementation and
reengineering will improve the efficiency and cost of processing accounting and
financial data,  but anticipates that the initial cost savings will be somewhat
offset by expenses associated with training costs and amortization of the new
computer software.

COST IN EXCESS OF NET ASSETS ACQUIRED ("GOODWILL"):

  Goodwill amortization for the fourth quarter and year ended November 30, 1998
was $.9 million and $3.6 million, respectively, principally reflecting the
amortization of the $124.1 million of goodwill recorded in connection with the
acquisition of Old MK. The Corporation allocated the purchase price of Old MK to
the assets acquired and liabilities assumed, including preacquisition
contingencies, on the basis of estimated fair values at September 11, 1996.
Resolution and revaluation of certain preacquisition contingencies and tax law
changes extending the net operating loss ("NOL") carryforward period from 15 to
20 years resulted in an adjustment to goodwill in the third quarter of 1997.
During the fourth quarter of 1998, management evaluated the likelihood of the
future realization of the tax benefits of deductible temporary differences and
NOL carryforwards relating to Old MK and concluded, based on available evidence,
that it is more likely than not that a portion of the tax benefits previously
reserved would be realized. This conclusion resulted in an increase in deferred
tax assets and a decrease in recorded goodwill of $20 million at November 30,
1998. The decrease in goodwill will reduce future annual goodwill amortization
by $.5 million. A further adjustment to deferred tax assets and related goodwill
may be likely in connection with the Corporation's pending acquisition of
certain businesses presently owned and operated by CBS Corporation. See Note 14.
"Acquisition of Westinghouse Businesses" of Notes to Consolidated Financial
Statements.

INVESTMENT INCOME:

  Investment income for the fourth quarter and year ended November 30, 1998
decreased $2.7 million and $3.3 million, respectively, from the comparable
periods of 1997 due to a decrease in interest recognized in 1997 from U.S.
federal income tax refunds received in January 1998 and a note receivable
collected in October 1997. These reductions in investment income were partially
offset by increased interest income on corporate cash in short-term asset
management accounts.

INTEREST EXPENSE:

  Interest expense for the fourth quarter and year ended November 30, 1998 of
$.2 million and $.9 million, respectively, was comparable to interest expense
incurred for the same periods of 1997. Interest expense consists 

                                      II-4
<PAGE>
 
primarily of periodic amortization of prepaid underwriting fees and quarterly
commitment fees in connection with the Corporation's five-year, $200 million
revolving loan and letter of credit facility obtained in the fourth quarter of
1996.

OTHER INCOME (EXPENSE), NET:

  Other income (expense)  for the fourth quarter and year ended November 30,
1998, of $1.5 million and $3.8 million, respectively, reflects the recognition
of $1.1 million and $3.2 million of income associated with the settlement of the
Corporation's defined benefit pension plan obligation. Final distribution of
surplus plan assets to eligible plan participants  is expected to be made in
early 1999.

  Other income (expense) for the quarter ended November 30, 1997 includes (i) a
$1.7 million income adjustment of the accrued pension benefit obligation
reflecting the  estimate of termination benefits to be settled with cash
proceeds from liquidation of plan assets and (ii) $1.9 million of expensed
acquisition costs associated with the Corporation's cancellation of the proposed
acquisition of Montana Resources, Inc. In addition, for the year ended November
30, 1997, the Corporation recognized an $.8 million loss on the sale of an
equity investment in a foreign bank and a $.6 million gain on adjustment of
insurance premiums paid in prior periods.

INCOME TAX EXPENSE:

  The effective tax rate for the fourth quarter and year ended November 30, 1998
was 44%, compared to 48% and 47% in the comparable periods of 1997, principally
due to a decrease in foreign tax expense and a lower proportion of non-
deductible expenses to pretax income. The effective tax rate is higher than the
U.S. federal statutory rate of 35% because of state income taxes and foreign
income taxes not currently eligible for use as credits against U.S. federal
income taxes and non-deductible expenses. It is anticipated that future foreign
income tax will be eligible for use as credits against U.S. federal income taxes
in 1999 and future periods.

1997 COMPARED TO 1996

THE CONSOLIDATED RESULTS OF OPERATIONS FOR THE YEAR ENDED NOVEMBER 30, 1996
INCLUDE THE RESULTS OF OLD MK FOR THE PERIOD FROM SEPTEMBER 12 TO NOVEMBER 30,
1996.

REVENUE AND GROSS PROFIT:

  Revenue and gross profit for the year ended November 30, 1997 increased
$1,018.2 and $46.0, respectively, compared to 1996 primarily due to the
acquisition of Old MK on September 11, 1996, which was accounted for as a
purchase. Gross profit, as a percent of revenue for the year, was 4.7%  for 1997
compared to 5.1% for 1996. During 1997, the Corporation's gross profit
benefitted from strong performances on several contracts which more than offset
the losses incurred on certain fixed-price contracts. In the fourth quarter of
1997, the Corporation assumed sponsorship of a large, fixed-price joint venture
due to the bankruptcy of the previous sponsor and recorded a $3.9 million pretax
loss because of the uncertainties on the project, including change orders and
potential project claims.

GENERAL AND ADMINISTRATIVE EXPENSES:

  General and administrative expenses for the year ended November 30, 1997
increased $.3 million compared to the year ended November 30, 1996. The
Corporation incurred approximately $1 million in expenses related to an
enterprise-wide implementation of new computer information systems for the
Corporation's financial, human resource and payroll functions.

IMPAIRMENT OF LONG-LIVED ASSETS:

  In 1996, the Corporation recognized impairment losses of $18.2 million on
certain real property held for sale or use and operating assets of a subsidiary
held for sale.

                                     II-5
<PAGE>
 
COST IN EXCESS OF NET ASSETS ACQUIRED ("GOODWILL"):

  Goodwill amortization for the year ended November 30, 1997 increased to $3.6
million from $1.2 million in 1996, reflecting the $124.1 million of goodwill
recorded in connection with the acquisition of Old MK. The Corporation allocated
the purchase price of Old MK to the assets acquired and liabilities assumed,
including preacquisition contingencies, on the basis of estimated fair values at
September 11, 1996. Resolution and revaluation of certain preacquisition
contingencies and the recent tax law change extending the NOL carryforward
period from 15 to 20 years, resulted in a net decrease in goodwill of $1.0
million in the third quarter of 1997. The extension of the NOL carryforward
period resulted in a decrease to goodwill of $19.7 million after adjusting the
valuation allowance related to the deferred tax asset. This decrease was offset
by an accrual for preacquisition contingencies of $18.7 million, primarily for
legal proceedings.

INVESTMENT INCOME:

  Investment income was comprised of (i) earnings from cash equivalents,
securities jointly held with customers as contract retentions and securities
available for sale, and (ii) interest on a note receivable collected in the
fourth quarter of 1997 and U.S. federal income tax refund receivables.
Investment income for the year ended November 30, 1997 increased $5.4 million
from 1996 principally due to interest recognized on U.S. federal income tax
refunds and earnings from securities available for sale.

INTEREST EXPENSE:

  Interest expense for the year ended November 30, 1997 decreased $.1 million
compared to 1996. Interest expense for 1997 consisted primarily of periodic
amortization of prepaid underwriting fees and quarterly commitment fees in
connection with the Corporation's five-year, $200 million revolving loan and
letter of credit facility obtained in the fourth quarter of 1996.

OTHER INCOME (EXPENSE), NET:

  Other expense for the year ended November 30, 1997 included (i) $1.7 million
income adjustment of the accrued pension benefit obligation reflecting the
estimate of termination benefits to be settled with cash proceeds from
liquidation of plan assets and (ii) $1.9 million of expensed acquisition costs
associated with the Corporation's cancellation of the proposed acquisition of
Montana Resources, Inc. In addition, the Corporation recognized an $.8 million
loss on the sale of an equity investment in a foreign bank and a $.6 million
gain on adjustment of insurance premiums paid in prior periods.

INCOME TAX EXPENSE:

  The effective tax rate for the year ended November 30, 1997 was 47%. The
effective rate was greater than the U.S. federal statutory rate of 35%,
primarily due to the impact of state and foreign income taxes and non-deductible
goodwill amortization. For the year ended November 30, 1996, the Corporation
recognized an income tax benefit of $.5 million which reflected recoverable
federal income taxes, net of foreign and state income tax expense.

FINANCIAL CONDITION AND LIQUIDITY

  The Corporation has three principal sources of near-term liquidity: (1)
existing cash and cash equivalents; (2) cash generated by its operations; and
(3) revolving loan borrowings under its credit facility. Management believes the
Corporation's liquidity and capital resources should be sufficient to meet its
reasonably foreseeable working capital, capital expenditure and other
anticipated cash requirements.

 Financing activities                   (29,734)    3,102
- ----------------------------------------------------------
</TABLE>

  Cash and cash equivalents increased $13.8 million during the year ended
November 30, 1998 to $67.1 million at November 30, 1998. This increase reflects
net cash provided from operating activities of $71.7 million offset by net cash
used in investing and financing activities of $28.1 million and $29.7 million,
respectively. The favorable operating cash flow for 1998 was attributable to
improved profitability and a greater focus on cash flow and working capital
management. Cash provided by operations also included $25.2 million from an
income tax refund and related interest; of which $18.0 million was applied as
required to the redemption  of the Corporation's Series A redeemable preferred
stock. These increases were partially offset by additional capital requirements
for three significant construction joint ventures in the Heavy Civil
Construction Group. Cash provided or used from operating activities from period
to period is affected to a large extent by the mix, timing, state of completion
and commercial terms of engineering and construction contracts which is
reflected in changes in net operating assets and liabilities. The Corporation
anticipates that the execution of existing backlog can be managed through future
operating cash flows and available cash and cash equivalents without need for
additional capital resources.

  Net cash used for investing activities in 1998 of $28.2 million included net
$20.5 million of property and equipment acquisitions, the net purchase of $5.9
million of securities available for sale in connection with the Corporation's
self-insured risk management program and $4.0 million primarily for the purchase
of a ready-mix concrete business offset by $2.8 million in cash proceeds from
the sale of a non-core business.

  Cash used in financing activities in 1998 of $29.7 million included $18.0
million for the redemption of the Corporation's Series A redeemable preferred
stock and $12.8 million for repurchase of 973,100 shares of the Corporation's
outstanding common stock. The Corporation received authorization in January 1998
to repurchase, in open market transactions, block trades or otherwise up to 2
million shares of the Corporation's outstanding common stock to counteract the
dilutive effect of the issuance of stock under its stock option plans, and up to
2.765 million of its warrants to purchase common stock. Subject to market
conditions and other factors, these purchases may be commenced, discontinued and
resumed from time to time without prior notice. It is anticipated that future
purchases will be funded from available cash and equivalents and operating cash
flows. Depending upon conditions in capital markets and other factors, the
Corporation may consider the possible issuance of long-term debt or other
securities.

  The Corporation anticipates capital expenditures for major construction
equipment of approximately $25 million 

                                      II-7
<PAGE>
 
during 1999 for normal replacement and to meet equipment requirements of its
expanding business.

  The Corporation has a five-year, $200.0 million revolving loan and letter of
credit facility from the Bank of Montreal. Under the credit facility,
outstanding revolving loan borrowings are limited to $125.0 million. During
1998, the Corporation had no outstanding borrowings under the facility and was
in compliance with its covenants, the most restrictive of which is fixed charge
coverage.

  The Corporation is subject to foreign currency translation and exchange
issues, primarily with regard to its mining venture, MIBRAG mbH, in Germany. At
November 30, 1998, the cumulative adjustments for translation losses net of
related income tax benefits was $3.0 million. The Corporation realized a pretax
gain on foreign currency exchange transactions of $358 thousand for the year
ended November 30, 1998. The Corporation endeavors to enter into contracts with
foreign customers with repayment terms in U.S. currency as a protection from
foreign exchange risk.

  As discussed in Note 14. "Acquisition of Westinghouse Businesses," the
Corporation intends to fund its share of the purchase price for certain
businesses presently owned and operated by CBS Corporation and its share of the
working capital requirements of such businesses using existing financing
facilities, additional financing facilities for which the Corporation has
received commitments or an offering of senior unsecured notes, together with
cash on hand and cash from other operations. The terms of such additional
borrowings have not yet been finalized.

  The Corporation may, from time to time, pursue opportunities to complement
existing operations through business combinations and participation in ventures,
which may require additional financing and utilization of the Corporation's
capital resources.

THE YEAR 2000 ISSUE

  The Year 2000 issue  is the result of computer programs written and electronic
circuitry that use two digits rather than four to define calendar years. These
programs may fail to properly differentiate between calendar years in the
twenty-first century and calendar years in the twentieth century (e.g., they may
recognize a date using "00" as the year 1900 rather than the year 2000). If not
corrected, the Year 2000 issue could result in complete system failures or
miscalculations causing significant disruption of normal business activities.
The Year 2000 issue affects virtually all companies and organizations, including
the Corporation.

  The Corporation employs a number of information technology ("IT") systems in
its operations including, without limitation, computer networking systems,
financial systems and other similar systems. Throughout its operations, the
Corporation also employs numerous non-IT devices such as building security and
safety devices and other devices containing embedded electronic circuits. Both
IT systems and non-IT devices are subject to potential failure or error due to
the Year 2000 issue.

  The Corporation has developed  and implemented a strategic plan (the "Year
2000 Project") to achieve Year 2000 readiness. The Year 2000 Project's
activities are intended to remediate the Year 2000 issue in all major categories
of systems and electronic devices in use by the Corporation, including IT
systems, non-IT devices and supply chain relationships so that the Corporation
may continue its operations without interruption or with minimal disruption. It
also includes communication with critical third parties such as clients,
vendors, subcontractors and other business partners to determine the expected
degree of Year 2000 compliance of those parties, and to monitor their progress
towards Year 2000 readiness. The Year 2000 Project includes the following
phases: (1) awareness, (2) inventory, (3) assessment, (4) remediation, (5)
testing/validation and (6) return to production. Progress reports on the Year
2000 Project are presented regularly to the Corporation's senior management and
periodically to the Audit Committee of the Board of Directors.

  Because of the scope of its operations, the Corporation believes it is
impractical to seek to eliminate all potential Year 2000 problems before they
arise. As a result, the Corporation expects that its Year 2000 assessments and
corrections will include ongoing remedial efforts into the year 2000. The
Corporation is using a risk-based analysis of 

                                      II-8
<PAGE>
 
its operations to identify those items that are critical to the Corporation and
at risk. Critical items are being identified through the "inventory" phase of
the Year 2000 Project.

  The Corporation is in various "inventory," "assessment" and "remediation"
phases with regard to its state of readiness related to non-IT devices
containing embedded circuitry and issues related to third parties with whom the
Corporation has material relationships. The Corporation is in various states of
the "inventory," "assessment," "remediation" and "testing/validation" phases
with regard to its IT systems.  As part of the Year 2000 Project regarding IT
systems, the Corporation continues implementing new or upgraded Year 2000
compliant systems for financial information, human resources and payroll.  These
systems  are expected to be completed in July, 1999.

  The Corporation is corresponding with its major clients and joint-venture and
other business partners, and with all vendors and subcontractors that have been
determined, through practical risk assessment techniques, to be  critical to the
Corporation, in order to determine the Year 2000 readiness or progress of those
entities and to assess any related risks.

  As part of the Year 2000 Project, the Corporation is exploring alternative
solutions and developing contingency plans to address the possibility that the
Corporation and third parties with whom it has material relationships will not
be fully Year 2000 ready on a timely basis. Such plans have not yet been fully
developed, and the Corporation will continue to develop them as necessary to
address each area of Year 2000 risk. Completion of the Year 2000 Project,
including the development of contingency plans, is expected by September 30,
1999.

  The Corporation's Year 2000 Project utilizes both internal and external
resources. The total cost of the Corporation's activities to achieve Year 2000
readiness is currently estimated at approximately $21.6 million. As of November
30, 1998, the direct costs incurred by the Corporation to remediate Year 2000
issues were approximately $6.7 million.

   Although the Corporation believes that its Year 2000 readiness efforts are
designed to appropriately identify and address those Year 2000 issues that are
within the Corporation's control, there can be no assurance that the
Corporation's efforts will be fully effective. The newness and complexity of the
issues presented and the Corporation's dependence on the technical skills and
preparedness of third parties are among the factors that could cause the
Corporation's efforts to be less than fully effective. Moreover, Year 2000
issues present many risks that are simply beyond the Corporation's control, such
as the potential effects of Year 2000 issues on the economy in general and on
the Corporation's business partners, vendors, subcontractors and customers in
particular.

  While the Corporation believes that the impact of any individual Year 2000
failure will most likely be localized and limited to specific facilities or
operations, the Corporation is not yet able to assess the likelihood of
significant business interruptions occurring in one or more of its operations
around the world. Such interruptions could prevent the Corporation, at least
temporarily, from delivering contractual services. Furthermore, it has been
widely reported that significant litigation is expected to occur related to
business interruptions caused by Year 2000 failures. It is uncertain whether, or
to what extent, the Corporation will be affected by such litigation. The failure
of the Corporation, its clients (including U.S. government agencies), vendors,
joint-venture partners or others upon whom the Corporation relies to achieve
Year 2000 readiness could adversely  affect the Corporation's business
operations, which could have a material adverse effect on the Corporation's
business, financial condition and results of operations.

  The foregoing disclosure is based upon the Corporation's current expectations,
estimates and projections, which could ultimately be found to be inaccurate.
Because of uncertainties and circumstances beyond the Corporation's control, the
actual effects of Year 2000 issues on the Corporation may be different than the
foregoing assessment. See "Note Regarding Forward-Looking Information."

ENVIRONMENTAL CONTINGENCY

  From July 1985 to June 1989, a subsidiary of the Corporation performed certain
contract mining services at the 

                                     II-9
<PAGE>
 
Summitville mine near Del Norte, Colorado. The EPA has notified the Corporation
and approximately 20 other parties that each is a potentially responsible party
("PRP") with regard to hazardous substances generated or disposed of at the
Summitville Mine Superfund Site ("Site"). The EPA has not commenced any
litigation or other proceedings against the Corporation. The Corporation has had
only preliminary discussions with the EPA but has been informally advised that
the EPA does not consider the Corporation eligible for a de minimis settlement
(the basis for settlement by several PRPs considered to have contributed less
than 3% volume and toxicity of the hazardous substances at the Site).

  According to a report published in August 1996, the EPA estimated that the
total remediation costs incurred and to be incurred at the Site will be $120.0
million. The Corporation is not a party to any agreement regarding an allocation
of responsibility, and the EPA has not made an allocation of responsibility
among the PRPs. The Corporation's share, if any, of the aggregate environmental
liability associated with the Site is not presently determinable and depends
upon, among other things, the manner in which liability may be allocated to or
among the Corporation or other PRPs associated with the Site, the efficacy of
any defenses that the Corporation or such other PRPs may have to any assertion
of liability, the willingness and ability of such other PRPs to discharge such
liability as may be allocated to them and the outcome of any negotiations or
settlement discussions between the Corporation and the EPA and/or such other
PRPs. Accordingly, no remediation costs have been accrued at November 30, 1998.
Management believes that the ultimate resolution of this matter could have a
material adverse effect on the Corporation's financial position and could
materially and adversely effect its results of operations and cash flows in one
or more periods.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
(IN THOUSANDS)

  The Corporation's exposure to market risk for changes in interest rates
relates primarily to the Corporation's short-and long-term investment portfolio
and debt obligations. The Corporation's short-term investment portfolio consists
primarily of highly liquid instruments with maturities of one month or less. The
Corporation's long-term investment portfolio consists primarily of high-quality
debt instruments with maturities under 10 years and an average maturity of 3.5
years. These long-term instruments are held to fund potential workers
compensation obligations of the Corporation. The Corporation seeks to match the
maturities of these instruments as closely as possible with its anticipated
workers compensation obligations and to hold these instruments to maturity in
order to minimize market risk exposure. As of November 30, 1998, the Corporation
had $39,644 of short-term investments classified as cash equivalents and $45,985
in its long-term investment portfolio.

  The Corporation may from time to time effect borrowings under its bank credit
facility for general corporate purposes, including working capital requirements,
capital expenditures and acquisitions. Borrowings under the bank credit facility
bear interest at the applicable LIBOR or base rate and, therefore, the
Corporation is subject to fluctuations in interest rates. As of November 30,
1998, the Corporation had no outstanding debt obligations.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Morrison Knudsen Corporation

  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, stockholders' equity and cash flows
present fairly, in all material respects, the financial position of Morrison
Knudsen Corporation and subsidiaries (the "Corporation") at November 30, 1998
and 1997, and the results of their operations and their cash flows for each of
the three years in the period ended November 30, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Corporation's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

  As discussed in Note 3 to the consolidated financial statements, the
Corporation changed its method of accounting for impairment of long-lived assets
in 1996 to conform with Statement of Financial Accounting Standards No. 121.

  As discussed in Note 13 to the consolidated financial statements, the
Corporation has been named as a potentially responsible party at the Summitville
Mine Superfund Site. The Corporation's share, if any, of the ultimate
environmental liability at the site is not presently determinable and,
accordingly, no remediation costs have been accrued in the accompanying
financial statements.

MORRISON KNUDSEN CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(IN THOUSANDS OF DOLLARS EXCEPT SHARE DATA)

  The term "Corporation" as used in this Annual Report includes Morrison Knudsen
Corporation and its consolidated subsidiaries unless otherwise indicated.

1.  SIGNIFICANT ACCOUNTING POLICIES

BUSINESS:

  The Corporation is a provider of (i) engineering and construction management
services to industrial companies, electric utilities and public agencies, (ii)
comprehensive environmental and hazardous substance remediation services to
governmental and private-sector clients, (iii) diverse heavy construction
services for the highway, airport, water resource, railway and commercial
building industries, and (iv) mine planning, engineering and contract mining
services for diverse customers. In providing such services, the Corporation
enters into three basic types of contracts: fixed-price or lump-sum contracts
providing for a fixed price for the total amount of work to be performed, unit-
price contracts providing for a fixed price for each unit of work performed, and
cost-type contracts providing for reimbursement of costs plus a fee.  Both
anticipated income and economic risk are greater under fixed-price and unit-
price contracts than under cost-type contracts. Engineering, construction
management and environmental and hazardous substance remediation contracts are
typically awarded on a cost-plus-fee basis.

  The Corporation also participates in construction joint ventures, often as
sponsor and manager of projects, which are formed for the sole purpose of
bidding, negotiating and completing specific projects. In addition, the
Corporation participates in the following mining ventures: Westmoreland
Resources, Inc., a coal mining company in Montana, and MIBRAG mbH, a company
that operates lignite coal mines and power plants in Germany.

PRINCIPLES OF CONSOLIDATION:

  The consolidated financial statements include the accounts of the Corporation
and all of its majority-owned subsidiaries. Investments in mining ventures and
all joint ventures are accounted for by the equity method. The Corporation's
proportionate share of construction joint-venture and mining venture revenue,
cost of revenue and gross profit (loss) is included in the consolidated
statements of operations. Intercompany accounts and transactions have been
eliminated.

REVENUE RECOGNITION:

  Revenue is generally recognized on a percentage-of-completion method.
Completion is generally measured for engineering and construction contracts
based on the proportion of costs incurred to total estimated contract costs. For
certain long-term contracts involving mining, environmental and hazardous
substance remediation, completion is measured on estimated physical completion
or units of production.

  Revenue recognition on certain fixed-price construction contracts begins when
progress is sufficient to estimate the probable outcome or on the completed
contract method if the probable outcome cannot be reasonably estimated. The
cumulative effect of revisions to contract revenue and completion costs,
including incentive awards, penalties, change orders and anticipated losses, is
recorded in the accounting period in which the amounts are known and can be
reasonably estimated.  Such revisions could occur at any time, and the effects
could be material. Revenue from claims are recorded, to the extent that contract
costs have been incurred, when it is probable that the claim will result in
additional contract revenue and it can be reliably estimated.

  The Corporation has a history of making reasonably dependable estimates of the
extent of progress towards completion, contract revenue and contract completion
costs on its long-term engineering and construction contracts. 

                                     II-19
<PAGE>
 
However, due to uncertainties inherent in the estimation process, it is possible
that actual completion costs may vary from estimates in the near term.

USE OF ESTIMATES:

  The preparation of the Corporation's consolidated  financial statements in
conformity with generally accepted accounting principles necessarily requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the balance sheet date and the reported amounts of revenue and costs during the
reporting periods. Actual results could differ in the near term from those
estimates.

UNBILLED RECEIVABLES:

  Unbilled receivables at November 30, 1998 arise from the use of the
percentage-of-completion method of accounting, cost reimbursement-type contracts
and the timing of billings. Substantially all of the unbilled receivables at
November 30, 1998 are expected to be billed and collected within one year.

CLASSIFICATION OF CURRENT ASSETS AND LIABILITIES:

  The Corporation includes in current assets and liabilities amounts realizable
and payable under engineering and construction contracts that extend beyond one
year. Accounts receivable at November 30, 1998 include approximately $2,180 of
contract retentions which are not expected to be collected within one year. At
November 30, 1998 accounts receivable include $1,931 of short-term marketable
securities jointly held with customers as contract retentions, the market value
of which approximated the carrying amounts. The Corporation recognizes interest
income from marketable securities as earned. Advances from customers are non-
interest bearing.

CASH EQUIVALENTS:

  Cash equivalents consist of liquid securities with original maturities of
three months or less readily convertible to known amounts of cash.

CREDIT RISK CONCENTRATION:

  The Corporation, by policy, limits the amount of credit exposure to any one
financial institution and places investments with financial institutions
evaluated as highly creditworthy. Concentrations of credit risk with respect to
accounts receivable and unbilled receivables are believed to be limited due to
the number, diversification and character of the obligors and the Corporation's
credit evaluation process. Typically, the Corporation has not required
collateral for such obligations, but can place liens against property, plant or
equipment constructed if a default occurs. Historically, the Corporation has not
incurred any material credit-related losses.

COST IN EXCESS OF NET ASSETS ACQUIRED:

  Cost in excess of net assets acquired in business combinations ("goodwill") is
amortized using the straight-line method over 40 years. The carrying value of
goodwill is reviewed for impairment on a quarterly basis. If impairment is
indicated by the facts and circumstances, an impairment loss will be recognized
based on a comparison of the carrying value of the long-lived assets and
associated goodwill with the undiscounted cash flow of such assets. The carrying
amount of the goodwill identifiable with such assets will be eliminated before
recognition of impairment of the related long-lived assets and identifiable
intangibles.

PROPERTY AND EQUIPMENT:

  Property and equipment is stated at cost. Major renewals and improvements are
capitalized, while maintenance and 

                                     II-20
<PAGE>
 
repairs are expensed when incurred. Depreciation of construction equipment is
provided on straight-line and accelerated methods, after an allowance for
estimated salvage value, over estimated lives of two to 10 years. Depreciation
of buildings is provided on the straight-line method over estimated lives of 10
to 20 years, and improvements are amortized over the shorter of the asset life
or lease term. Depreciation of equipment, principally computer systems, is
provided under the straight-line method generally over three to five years. Upon
disposition, cost and related accumulated depreciation of property and equipment
are removed from the accounts and the gain or loss is reflected in results of
operations.

FOREIGN CURRENCY TRANSLATION:

  The functional currency for foreign operations is generally the local
currency. Translation of assets and liabilities to U.S. dollars is based on
exchange rates at the balance sheet date. Translation of revenue and expenses to
U.S. dollars is based on a weighted-average exchange rate during the period.
Translation gains or losses, net of income tax effects, are reported as a
component of stockholders' equity for foreign subsidiaries. Because of the
short-term duration of construction and engineering projects, related
translation gains or losses are recognized currently. Gains or losses from
foreign currency transactions are included in the results of operations of the
period in which the transaction is completed.

ENVIRONMENTAL LIABILITIES:

  Accruals for estimated costs of response actions for environmental matters are
recorded when it is probable that a liability has been incurred and the amount
of the liability can be reasonably estimated. On a quarterly basis, the
Corporation reviews estimates of costs of response actions at various sites,
including sites in respect of which government agencies have designated the
Corporation as a potentially responsible party. Accrued liabilities may be
discounted and are exclusive of claims for recovery, if any. However, due to
uncertainties inherent in the estimation process, it is  possible that actual
results may vary from estimates in the near term.

INCOME TAXES:

  Deferred income tax assets and liabilities are recognized for the effects of
temporary differences between the carrying amounts and the income tax basis of
assets and liabilities using enacted tax rates. A valuation allowance is
established when it is more likely than not that net deferred tax assets will
not be realized. Tax credits are recognized in the year they arise.

INCOME (LOSS) PER SHARE:

  Basic income (loss) per share is based on the weighted-average number of
outstanding common shares during the applicable period. Diluted income (loss)
per share is based on the weighted-average number of outstanding common shares
plus the weighted-average number of potential outstanding common shares. The
additional weighted-average number of potential outstanding common shares for
purposes of computed diluted earnings per share consisted solely of stock
options for all periods presented. Income (loss) per share is computed
separately for each quarterly and annual period presented.

RECLASSIFICATIONS:

  Certain reclassifications have been made in prior period financial statements
to conform to the 1998 presentation.

2.  BUSINESS COMBINATION

  On September 11, 1996, the Corporation (which was then known as Washington
Construction Group, Inc.) acquired the net assets and the engineering and
construction operations of Morrison Knudsen Corporation ("Old MK") for $221,736,
and changed its name to Morrison Knudsen Corporation.

                                     II-21
<PAGE>
 
  The purchase price consisted of (i) $13,300 of cash, (ii) 24,161,421 newly
issued shares of common stock of the Corporation valued at $180,364 in the
aggregate, or $7.465 per share, (iii) 1,800,000 newly issued shares of preferred
stock valued at $18,000, (iv) warrants to purchase 2,952,848 shares of the
Corporation's common stock at $12.00 per share valued at $6,564, and (v) $3,508
of acquisition costs. The acquisition of Old MK was structured as a merger of
Old MK with and into the Corporation and was accounted for using the purchase
method of accounting. The purchase price was allocated to the assets acquired
and liabilities assumed based on estimated fair values at September 11, 1996.
The consolidated results of operations for periods subsequent to September 11,
1996 reflect the merged operations. The cost in excess of the net assets
acquired is being amortized under the straight-line method over 40 years.

  The following unaudited pro forma information presents the Corporation's
consolidated results of operations as if the acquisition of Old MK had occurred
on December 1, 1995 and after giving effect to certain adjustments, including
amortization of goodwill, depreciation expense, reduction in investment income
and related tax effects. The unaudited pro forma results of operations for 1996
include Old MK's results of operations for the eleven months ended November 30,
1996. The pro forma results of operations for 1996 reflect certain adjustments
made in 1997 to reflect revenue on mining ventures consistent with the 1997
presentation and to eliminate certain after tax losses on disposal of assets and
professional fees. Such pro forma information does not purport to be indicative
of operating results that would have been reported had the acquisition of Old MK
occurred on December 1, 1995 or of future operating results.

3.  ADOPTION OF ACCOUNTING PRINCIPLE

  During 1998, the Corporation adopted Statement of Financial Accounting
Standards No. 128 Earnings Per Share ("SFAS No. 128") which changed the standard
for computing and presenting earnings per share ("EPS"). Basic EPS excludes
dilution and is computed by dividing net income by the weighted-average number
of shares outstanding for the period. Diluted EPS is computed by dividing net
income by the sum of the weighted-average number of shares outstanding plus the
weighted-average number of potential common shares outstanding. Potential common
shares consist of shares issuable upon the exercise of stock options and
warrants. Earnings per share computations exclude stock options and potential
shares for stock purchase warrants to the extent that their effect would be
antidilutive.

  During 1998, the Corporation also adopted the provisions of Statement of
Position ("SOP") 98-1 Accounting for Costs of Computer Software Developed or
Obtained for Internal Use issued by the American Institute of Certified Public
Accountants. The SOP provides guidance on accounting for the costs of computer
software developed or obtained for internal use. In general, the SOP calls for
expensing software costs incurred in the preliminary project stage and post-
implementation/operation stage and the capitalization of software costs incurred
during the application development stage, including payroll and payroll-related
costs for employees who are directly associated with the 

                                     II-22
<PAGE>
 
project.

  In the third quarter of 1996, the Corporation adopted Statement of Financial
Accounting Standards No. 121 Accounting for the Impairment of Long-Lived Assets
and Long-Lived Assets to be Disposed of , which requires that long-lived assets
and certain identifiable intangible assets be periodically reviewed for
impairment. The impairment loss on long-lived assets aggregating $18,200 in 1996
was comprised of the following:

  (i) The Corporation's Board of Directors approved a plan to offer for sale
  certain assets of a non-core subsidiary with a carrying amount of $17,486 at
  August 31, 1996. The Corporation recognized an estimated impairment loss of
  $6,500 to reduce the carrying amount of the assets to estimated fair value.

  (ii) Land previously held primarily for lease with a carrying amount of $8,266
  at August 31, 1996 was reclassified to land held for sale. The Corporation
  recognized an estimated impairment loss of $5,600 and established a new
  carrying amount of $2,666 at August 31, 1996, based upon an appraisal of the
  current fair value net of the estimated improvement and disposal costs
  required for a near-term bulk sale of the land.

  (iii) As of August 31, 1996, the Corporation recognized an estimated
  impairment loss of $6,100 on the land and buildings in Highland, California,
  which comprised the Corporation's headquarters prior to relocation of the
  headquarters to Boise, Idaho. The loss reflects the change in use and the
  impairment of the $7,016 carrying amount of the Highland property. The
  impairment loss was estimated based on an appraisal of the current fair value.

4. RECENTLY ISSUED ACCOUNTING STANDARDS

  In June 1997, the Financial Accounting Standards Board issued Statement No.
130 Reporting Comprehensive Income ("SFAS No. 130"). SFAS No. 130 establishes
standards for the reporting and display of comprehensive income but does not
effect the current principles of measurement of revenue. Comprehensive income is
defined as the change in equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources. The
adoption of SFAS No. 130 is effective for the Corporation  commencing with the
quarter ending February 28, 1999.

  In June 1997, the Financial Accounting Standards Board issued Statement No.
131 Disclosures about Segments of an Enterprise and Related Information ("SFAS
No. 131"). SFAS No. 131 requires publicly-held companies to report segment and
other financial information which is utilized by the chief operating decision
maker and to reconcile the segment information to financial statement amounts.
Specific information to be reported for individual segments includes profit or
loss, certain revenue and expense items and total assets. SFAS No. 131 is
effective for the Corporation commencing with the year ending November 30, 1999.

  In February 1998, the Financial Accounting Standards Board issued Statement
No. 132 Employers' Disclosures about Pensions and Other Postretirement Benefits
- - an amendment of FASB Statements No. 87, 88 and 106 ("SFAS No. 132"). SFAS No.
132 revises and standardizes the disclosure requirements for pensions and other
postretirement benefits, requires additional information on changes in the
benefit obligations and fair values of plan assets and eliminates certain
disclosures previously required. SFAS No. 132 does not change the measurement or
recognition of those plans. SFAS No. 132 is effective for the Corporation
commencing with the year ending November 30, 1999.

  In June 1998, the Financial Accounting Standards Board issued Statement No.
133 Accounting for Derivative Instruments and Hedging Activities ("SFAS No.
133"). SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts and for hedging activities. The statement requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
Corporation is currently evaluating the effect of SFAS No. 133 will have on

  Undistributed earnings from mining ventures totaled $19,295 at November 30,
1998.

  On December 23, 1996, Westmoreland Coal and four subsidiaries, including
Westmoreland Resources, filed for protection under Chapter 11 of the United
States Bankruptcy Code. Effective at the beginning of July 1998, the Corporation
temporarily suspended recording its equity in the income of Westmoreland
Resources pending the outcome of the proceedings. Subsequently, Westmoreland and
its creditors compromised and resolved their differences and, on December 23,
1998, the Chapter 11 bankruptcy case was dismissed. As a result, the
Westmoreland mining contracts with the Corporation remain in full force and
effect and the Corporation's equity interest in Westmoreland Resources is
unaffected.

7.  ASSETS HELD FOR SALE

  At November 30, 1998, assets held for sale are stated at the lower of cost or
fair value less cost of disposal and are comprised of the net assets of a
subsidiary. The Corporation is unable to predict disposal dates. Operations of
the subsidiary resulted in revenue of $20,200 and $5,300, and net losses of $12
and $937 for 1998 and 1997, respectively. During 1998, land held for sale was
sold at approximate book value of $2,758. During 1997, a 29.5% stock ownership
interest in a foreign bank which had a carrying amount of $5,244 at November 30,
1996 was sold at a loss of $833. In 1996, the Corporation recognized aggregate
impairment losses of $12,100 on assets held for sale and $6,100 on assets held
for use.

8.  CREDIT FACILITIES

  On October 31, 1996, the Corporation obtained from the Bank of Montreal a
five-year, $200,000 revolving loan and letter of credit facility  (the
"Facility"). Revolving loan borrowings under the Facility are limited to
$125,000. On October 8, 1997, the Facility was extended for an additional year
to October 2002. Annually thereafter, the Facility may be extended by an
additional year upon mutual approval of the bank and the Corporation.

  Substantially all of the assets of the Corporation and certain of its material
domestic subsidiaries are pledged  to collateralize the Corporation's
obligations under the Facility. The Facility covenants require the maintenance
of financial ratios, the most restrictive of which is fixed charge coverage and
minimum levels of net worth, and place limitations on additional indebtedness,
guarantees, liens, investments and  other matters. At November 30, 1998, the
Corporation had no outstanding borrowings under the Facility and was in
compliance with the covenants. The Corporation is not restricted from paying
dividends unless an event of default exists.

  The Facility provides for loans bearing interest, payable quarterly, at the
applicable LIBOR rate or the base rate, as defined, plus an additional margin.
The additional margin ranges from 3/4% to 1 1/8% for the LIBOR rate and zero to
1/4% for the base rate, based on the ratio of earnings before interest, taxes,
depreciation and amortization to the Corporation's funded debt. In 1996, the
Corporation paid a $1,100 underwriting fee to the bank and is required to pay
annual/quarterly commitment and letter of credit fees.

</TABLE>

  At November 30, 1998, the Corporation had consolidated regular tax net
operating loss carryforwards for federal, state and foreign tax purposes of
approximately $211,137, $194,654 and $3,775, respectively, which expire in the
years 2000 through 2012. In addition, the Corporation had federal alternative
minimum tax credits of $13,731 at November 30, 1998 which carry forward
indefinitely. The $91,987 valuation allowance reduces these net operating loss
carryforwards and other deferred tax assets to a level which management believes
will, more likely than not, be realized based on estimated future taxable
income. The net decrease of $20,000 in the valuation allowance at November 30,
1998 resulted from an evaluation of the likelihood of the future realization of
deductible temporary differences and net 

                                     II-27
<PAGE>
 
operating loss carryforwards of Old MK. The reduction in the valuation allowance
was recorded as a reduction of goodwill related to the acquisition of Old MK.
Any future reduction in the valuation allowance related to tax assets acquired
at September 11, 1996 will result in a reduction of goodwill. The valuation
allowance may be increased based on the occurrence of future events, and any
such increase could be material. Years prior to 1994 are closed to examination
for federal tax purposes. Management believes that adequate provision has been
made for probable tax assessments.

  Income tax expense (benefit) differed from income taxes at the U.S. federal
statutory tax rate of 35% as follows:

expenses.

  Income (loss) before income taxes was comprised of a domestic source income of
$40,366 and foreign source income of $27,039 in 1998, domestic source income of
$28,725 and foreign source income of $31,171 in 1997 and a domestic source loss
of $(6,406) and foreign source income of $1,132 in 1996.

10.  BENEFIT PLANS

PENSION PLAN:

  The Corporation terminated its defined benefit pension plan in 1997. During
1998, a settlement of the plan's accumulated vested termination benefit
obligation was effected through a combination of lump-sum cash payments and the
purchase of a nonparticipating group annuity contract. As a result of this
termination, other income of  $3,161 was recognized during 1998. At November 30,
1998, approximately  $4,348 in excess plan assets remain in trust and are
expected to be distributed equally after payment of final plan expenses to
eligible plan participants early in 1999. All of these remaining excess assets
are invested in cash equivalents pending this final distribution.

MULTIEMPLOYER PENSION PLANS:

  The Corporation participates in and makes contributions to numerous
construction-industry multiemployer pension plans. Generally, the plans provide
defined benefits to substantially all employees covered by collective bargaining
agreements. Cost of the plans was $18,871 in 1998, $16,098 in 1997 and $4,972 in
1996. Under the Employee Retirement Income Security Act, a contributor to a
multiemployer plan is liable, upon termination or withdrawal from a plan, for
its proportionate share of a plan's unfunded vested liability. The Corporation
currently has no intention of withdrawing from any of the multiemployer pension
plans in which it participates.

  Participants do not accrue any service cost under the plans. There was no
interest expense associated with the pension liability for former non-employee
directors in 1998, 1997 and 1996, as the full, undiscounted liability is
included in the accumulated vested benefit obligation ("ABO"). Pension expense
(consisting entirely of interest on the unfunded current and former employee
ABO) for 1998, 1997 and 1996 was $928, $955 and $207.

POSTRETIREMENT HEALTH CARE PLAN:

  The Corporation succeeded Old MK as sponsor of an unfunded plan to provide
certain health care benefits for employees of Old MK who retired before July 1,
1993, including their surviving spouses and dependent children. Employees who
retired after July 1, 1993 are not eligible for company subsidized
postretirement health care benefits. The plan was amended in past years, and the
Corporation reserves the right to amend or terminate the postretirement health
care benefits currently provided under the plan and may increase retirees' cash
contributions at any time.

  The unrecognized prior service cost is being amortized to periodic health care
expense over the 13-year average future expected lifetime of retirees and their
surviving spouses beginning in fiscal 1997, the date of the last plan change.

  The accumulated postretirement benefit obligation ("APBO") was determined
using the projected unit credit method and assumed discount rates of 6.5% and 7%
in 1998 and 1997, respectively. In addition, an annual rate increase of 8.5% in
the per capita cost of health care benefits was assumed, gradually declining to
4.5% in the year 2007 and continuing thereafter at that rate over the projected
payout period of the benefits. The health care cost trend rate assumption has a
significant effect on the APBO. For example, a 1% increase in the health care
cost trend rate would increase the APBO at November 30, 1998 by approximately
$3,837 and increase the 1998 expense by approximately $294.

DEFERRED COMPENSATION PLANS:

  The Corporation adopted a deferred compensation plan effective January 1, 1998
for the benefit of executive officers and key employees. The unfunded plan
allows participants to elect to defer salary and bonus subject to certain
limits. An accrued liability for the plan of $2,202 has been accrued at November
30, 1998.

OTHER RETIREMENT PLANS:

  The Corporation also sponsors a number of defined contribution retirement
plans. Participation in these plans is available to substantially all salaried
employees and to certain groups of hourly employees. The Corporation's cash
contributions to these plans are based on either a percentage of employee
contributions or on a specified amount per hour based on the provisions of each
plan. Costs associated with these plans totaled $12,219, 12,354 and $3,192 for
1998, 1997 and 1996, respectively.

  The net cost of all of the above plans was  $31,408 in 1998, $30,846 in 1997
and $9,174 in 1996.

  In January 1998, the Corporation and a brokerage firm owned by a member of the
Board of Directors approved a new agreement for insurance and bond services
supplied to the Corporation effective January 1, 1998 and expiring December 31,
2000, with automatic renewal annually for 12-month terms thereafter, unless
canceled by either party prior to the annual date. Pursuant to the agreement,
the brokerage firm receives an annual fixed fee of $1,150, which will be paid in
equal quarterly installments with all insurance commissions earned to be
credited 100% against the fee.

  Negotiations of the proposed acquisition of an interest in a copper mine
between the Corporation and a principal stockholder and the Chairman of the
Board of Directors were terminated in January, 1998.

13.  CONTINGENCIES AND COMMITMENTS

SUMMITVILLE ENVIRONMENTAL MATTERS:

  From July 1985 to June 1989, a subsidiary of the Corporation performed certain
contract mining services at the Summitville mine near Del Norte, Colorado. The
United States Environmental Protection Agency (the "EPA") has notified the
Corporation and approximately 20 other parties that each is a potentially
responsible party ("PRP") with regard to hazardous substances generated or
disposed of at the Summitville Mine Superfund Site (the "Site"). The EPA has not
commenced any litigation or other proceedings against the Corporation. The
Corporation has had only preliminary discussions with the EPA but has been
informally advised that the EPA does not consider the Corporation eligible for a
de minimis settlement (the basis for settlement by several PRPs considered to
have contributed less than 3% volume and toxicity of the hazardous substances at
the Site).

  According to a report published in August 1996, the EPA estimated that the
total remediation costs incurred and to be incurred at the Site will be
$120,000. The Corporation is not a party to any agreement regarding an
allocation of responsibility, and the EPA has not made an allocation of
responsibility among the PRPs. The Corporation's share, if any, of the aggregate
environmental liability associated with the Site is not presently determinable
and depends upon, among other things, the manner in which liability may be
allocated to or among the Corporation or other PRPs associated with the Site,
the efficacy of any defenses that the Corporation or such other PRPs may have to
any assertion of liability, the willingness and ability of such other PRPs to
discharge such liability as may be allocated to them and the outcome of any
negotiations or settlement discussions between the Corporation and the EPA
and/or such other PRPs. Accordingly, no remediation costs have been accrued at
November 30, 1998.

  Management believes that the ultimate resolution of this matter could have a
material adverse effect on the Corporation's financial position and could
materially and adversely effect its results of operations and cash flows in one
or more periods.

OTHER ENVIRONMENTAL MATTERS:

  The Corporation has been identified as a PRP and is contingently liable for
remediation liabilities in connection with Old MK's former Transit business. The
Corporation agreed to indemnify the buyer of the Transit business for
remediation costs and has therefore accrued $3,000. While the Corporation's
range of loss cannot be estimated, management believes that the ultimate outcome
of the matter will not have a material adverse effect on the Corporation's
financial position, results of operations or cash flows.

                                     II-32
<PAGE>
 
  The Corporation has assumed an undiscounted liability of Old MK which at
November 30, 1998 was $1,753 for environmental cleanup activities at four other
sites. The Corporation estimates that such costs could range from $1,000 to
$1,800 in the aggregate.

CONTRACT RELATED MATTERS:

  In 1995, Old MK entered into a fixed-price contract with the Texas Natural
Resource Conservation Commission ("TNRCC") for construction of a solvent-
extraction facility and treatment of contaminated soil at a Superfund site in
Texas. The TNRCC notified the Corporation in February 1998 that it was
terminating its contract with the Corporation. In the fourth quarter of 1998,
the Corporation received $1,600 as settlement for all issues relating to this
contract, and the TNRCC has released the Corporation's letter of credit in the
amount of $13,619 that had been provided by the Corporation to collateralize its
obligations under the contract.

  In the fourth quarter of 1997, the Corporation assumed sponsorship of a large,
fixed-price joint-venture contract due to the bankruptcy of the previous sponsor
and recorded a $3,900 pretax loss due to uncertainties on the project, including
unpaid client-directed change orders and potential project claims. Management
believes that acceptable pricing will be achieved by further negotiation with
the client. The ultimate outcome cannot be currently determined with certainty
and may not occur in the near term.

  The Corporation has a number of cost reimbursable contracts with the U.S.
government, the allowable costs of which are subject to adjustments upon audit
and negotiation by various agencies of the U.S. government. Audits and
negotiations of the Corporation's allocation of periodic costs of insurance
programs are complete through 1997, resulting in a $4,300 credit refund by the
Corporation to certain U.S. government contracts to be applied over two years.
Audits and negotiations of indirect costs are substantially complete through
1996. The anticipated adjustment in favor of the government is $1,000 for which
the Corporation has previously established a reserve. Audits of 1997 indirect
costs are in progress.

LETTERS OF CREDIT:

  In the normal course of business, the Corporation causes letters of credit to
be issued in connection with contract performance obligations which are not
reflected in the balance sheet. The Corporation is obligated to reimburse the
issuer of such letters of credit for any payments made thereunder. At November
30, 1998 and 1997, $37,157 and $41,297, respectively, in face amount of such
letters of credit were outstanding. The Corporation has pledged securities
available for sale as collateral for its reimbursement obligations in respect of
$3,443 in face amount of certain letters of credit that were outstanding at
November 30, 1998.

  In connection with a 1989 sale of Old MK's ownership interest of a
shipbuilding subsidiary, the Corporation assumed a guarantee of port facility
bonds of $21,000 through 2002. The former subsidiary has collateralized the
bonds with certain assets and has established a sinking fund of $5,272 for the
bonds. No loss on the guarantee is probable and, accordingly, no accrual has
been made by the Corporation.

LONG-TERM LEASES:

  Total rental payments for real estate and equipment under lease charged to
operations in 1998, 1997, and 1996 were $52,067, $36,575 and $11,780,
respectively. Future minimum rental payments under operating leases, some of
which contain renewal or escalation clauses, with remaining noncancelable terms
in excess of one year at November 30, 1998 were as follows:

OTHER:

  In May 1998, Leucadia National Corporation filed an action against the
Corporation and certain officers and directors in The United States District
Court for the District of Utah, Civil Action Number 2:98CV-0327S. The complaint
alleges fraud in the sale of shares of MK Gold Corporation by Old MK to Leucadia
and seeks rescission of the sale and restitution of $22,500. Leucadia contends
that the Corporation knew or believed that a non-competition agreement between
the Corporation and MK Gold was unenforceable and failed to disclose that belief
to Leucadia. The non-competition agreement is the subject of separate litigation
between MK Gold and the Corporation. On January 5, 1999, the two cases were
consolidated for trial. No trial date has been set.

  The Corporation and certain current and former officers, employees and
directors were named defendants in two legal actions: John B. Blyler and Malcolm
J. Corse v. William J. Agee, et. al., Civil Action No. 97-0332-S-BLW ("Blyler
case") and Martin Radwell v. Dennis R. Washington, et. al., Civil Action No.
15934 ("Radwell case"). The complaint in the Blyler case alleges, among other
things, that the defendants breached certain fiduciary duties. The Radwell case
was dismissed in 1998 following stockholder approval of a settlement between the
parties. The settlement amount was not material.

  Although the ultimate outcome of these matters cannot be predicted with
certainty, management believes that the outcome of these actions, individually
or collectively, will not have a material adverse impact on the Corporation's
financial position, results of operations or cash flows.

  In addition to the foregoing, there are other claims, lawsuits, disputes with
third parties, investigations and administrative proceedings against the
Corporation and its subsidiaries relating to matters in the ordinary course of
its business activities that are not expected to have a material adverse effect
on the Corporation's financial position, results of operations or cash flows.

14.  ACQUISITION OF WESTINGHOUSE BUSINESSES

  On June 26, 1998, the Corporation announced the formation of a joint venture
with British Nuclear Fuels, Ltd. ("BNFL") to acquire  certain businesses (the
"Westinghouse businesses") from CBS Corporation (formerly known as Westinghouse
Electric Corporation). The transaction is subject to regulatory approvals and is
expected to close in  the second quarter of 1999. The Westinghouse businesses,
which consist of the Government and Environment Services Company ("GESCO") and
the Energy Systems Business Unit ("ESBU"), and which are both divisions of CBS
Corporation, provide a wide range of products, services and technologies in the
government services and nuclear industries throughout the world.

  GESCO manages highly complex facilities and programs for the United States
Departments of Energy and Defense. GESCO also provides a wide range of services
at government installations, including the production of tritium for national
weapons programs and high-level waste solidification. GESCO employs over 13,000
employees, including those at government-owned, contractor-operated locations.

  ESBU provides commercial nuclear power technology with emphasis on service,
fuel and instrumentation and control technologies for the world's operating
nuclear power plants. ESBU is also heavily involved in the development of new
plant technology and has received final design approval from the Nuclear
Regulatory Commission for its advanced nuclear power plant, the AP600. ESBU has
approximately 4,000 employees.

   The Corporation was informed by CBS that the Department of the Navy has
chosen another party to perform certain contracts which were to be part of the
acquisition of the Westinghouse businesses and that CBS Corporation had formally
protested the award of those Navy contracts. This protest was unsuccessful. The
purchase price for the acquisition of the Westinghouse businesses has,
therefore, been adjusted downward by $38,000 to approximately $1,150,000
(consisting of $200,000 in cash and the assumption of approximately $950,000 in
specified liabilities, commitments and obligations). Under the  transaction
structure currently proposed, the Corporation's share of the purchase price
would be approximately $120,000 in cash.

  During the second half of 1998, the Corporation and BNFL entered into
negotiations with GESCO's primary client, the Department of Energy, regarding
the transfer of GESCO and ESBU and the contracts that each of those units has
with the Departments of Energy and Defense. As a result of those negotiations,
the Corporation and BNFL have proposed a transaction structure pursuant to which
(1) the Corporation and BNFL would form three limited liability companies -
Westinghouse Government Services Company, L.L.C. ("WGS"), which would acquire
the portion of GESCO's business relating to defense program services -
Westinghouse Government Environmental Services Company, L.L.C. ("WGES"), which
would acquire the portion of GESCO's business relating to environmental
remediation and waste management services - and Westinghouse Electric Company,
L.L.C. ("WEC"), which would acquire ESBU, (2) the Corporation would hold 100% of
the membership interests in WGS and 60% of the membership interests in WGES and
BNFL would hold 100% of the membership interests in WEC and 40% of the
membership interests in WGES, and (3) the Corporation would assign a passive
economic right to 40% of profits and losses of WGS to BNFL. These arrangements
are subject to final Department of Energy approval and approval by the Committee
on Foreign Investment in the United States.

  The Corporation intends to fund its share of the purchase price and the
working capital requirements of the Westinghouse businesses using existing
financing facilities, additional financing facilities for which the Corporation
has received commitments or an offering of senior unsecured notes, together with
cash on hand and cash from other operations. The terms of such additional
borrowings have not yet been finalized.

16.  REDEEMABLE PREFERRED STOCK

  On September 11, 1996, the Corporation issued 1,800,000 shares of Series A
preferred stock in connection with the acquisition of Old MK. On April 15, 1998,
all of the Series A preferred stock was redeemed, in accordance with terms, with
$18,000 of federal income tax refunds received by the Corporation in January
1998.

17.  CAPITAL STOCK, STOCK PURCHASE WARRANTS AND STOCK COMPENSATION PLAN

CAPITAL STOCK:

  Pursuant to its Certificate of Incorporation, the Corporation has the
authority to issue 100,000,000 shares of common stock and 10,000,000 shares of
preferred stock. Preferred stock may be issued at any time or from time to time
in one or more series with such designations, powers, preferences and rights,
qualifications, limitations or restrictions thereof as determined by the Board
of Directors of the Corporation.

STOCK PURCHASE WARRANTS:

  At November 30, 1998, the Corporation had outstanding stock purchase warrants
giving rights to acquire 2,945,582 shares of the Corporation's common stock at
an exercise price of $12.00 per share. Of such warrants 2,757,734 expire in
March 2003, and 187,848 expire in September 2001.

STOCK REPURCHASE PROGRAM:

  In January 1998, the Board of Directors authorized the purchase, from time to
time, of up to 2 million shares of the Corporation's common stock to counteract
the dilutive effect of the issuance of stock under its stock option plans and up
to 2.765 million of its stock purchase warrants. As of November 30, 1998,
973,100 shares have been repurchased at a cost of $12,848.

                                     II-36
<PAGE>
 
STOCK COMPENSATION PLAN:

  The Corporation has a stock compensation plan for employees and non-employee
directors  (the "1994 plan") which provides for grants in the form of
nonqualified stock options or incentive stock options ("ISOs") and restricted
stock awards. Additional shares of common stock available each year for grants
under the 1994 plan are equal to 3% of the outstanding shares as of  the first
day of such year.  Exercise prices for nonqualified stock options are determined
by the Board of Directors. Exercise prices for ISOs are equal to the fair market
value of the Corporation's common stock at the date of grant. Stock options
extend for and vest over periods of up to ten years as determined by the Board.
The Board may accelerate the vesting period after award of an option. The number
of shares available for grant of ISOs may not exceed 2,900,000 shares, and no
individual shall be granted stock options or restricted stock awards for more
than 5,000,000 shares over any three-year period.

  Non-employee directors may elect to forego receipt in cash of certain fees
earned during any year in return for an option with a grant price equal to 80%
of the fair market value of the Corporation's common stock,  vesting quarterly
during the year with a term period of up to ten years as determined by the
Board. Non-employee directors elected options for 88,204,  95,556 and 50,461
shares in lieu of fees earned in 1998, 1997 and 1996, respectively.

  On April 11, 1997, the Corporation's stockholders adopted the 1997 Stock
Option and Incentive Plan for Non-employee Directors (the "1997 plan") which
provides for grants in the form of nonqualified stock options and restricted
stock awards. Grant prices per share for stock options are at fair market value
at the date of grant. The number of shares available for grant as options and
restricted stock awards is 500,000, of which no more than 100,000 may be awarded
as restricted. Grants of nonqualified stock options and restricted stock awards
to the non-employee directors under the 1997 plan do not preclude grants under
the 1994 plan. Options are subject to terms and conditions determined by the
Board of Directors and have a term not exceeding 10 years from the date of
grant. Option activity under the Corporation's stock plans is summarized as
follows:

  The terms and conditions of restricted stock awards issued to key employees
are determined by the Board. Upon termination of employment, shares that remain
subject to restriction are forfeited. At November 30, 1998, there were no
restricted shares outstanding. No restricted stock awards were made in 1998,
1997 and 1996.

STOCK-BASED COMPENSATION:

  The Corporation has adopted the disclosure-only provisions of the Financial
Accounting Standards Board Statement No. 123 Accounting for Stock-Based
Compensation ("SFAS No. 123") issued in October 1995. Accordingly, compensation
cost has been recorded based on the intrinsic value of the option only. The
Corporation recognized $219, $477 and $702 of compensation cost in 1998, 1997
and 1996, respectively, for stock-based employee compensation awards. If the
Corporation had elected to recognize compensation cost based on the fair value
of the options granted at grant date as prescribed by SFAS No. 123, net income
and earnings per share would have been reduced to the pro forma amounts as
follows:
<TABLE>
<CAPTION>

 Pro forma - basic and diluted        .67      .57     (.13)
- -------------------------------------------------------------------
</TABLE>

  The pro forma amounts set forth above reflect the portion of the estimated
fair value of awards earned in 1998, 1997 and 1996 based on the vesting period
of the options. The pro forma effects disclosed above are not likely to be
representative of the pro forma disclosures of future years because SFAS No. 123
is applicable only to options granted subsequent to November 30, 1995, the
effect of which will not be fully reflected until 1999.

  The Black-Scholes option valuation model was used to estimate the fair value
of the options for purposes of the pro forma presentation set forth above.

  The following assumptions were used in the valuation and no dividends were
assumed:
<TABLE>

 Exercise price less than market price at grant    $7.80   $ 7.20       -
- --------------------------------------------------------------------------
</TABLE>

  The assumptions used in the Black-Scholes option valuation model are highly
subjective, particularly as to stock price volatility of the underlying stock,
and can materially affect the resulting valuation. In management's opinion, the
model does not provide a reliable single measure of the fair value of the
employee stock options.

18.  FINANCIAL INSTRUMENTS

  The estimated fair values of financial instruments at November 30, 1998 have
been determined by the Corporation, using available market information and
valuation methodologies believed to be appropriate. However, judgment is
necessary in interpreting market data to develop the estimates of fair values.
Accordingly, the estimates presented herein are not necessarily indicative of
the amounts that the Corporation could realize in a current market exchange. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts.

  The carrying amounts and estimated fair values of certain financial
instruments at November 30, 1998 and 1997 were as follows:

securities available for sale based on quoted market prices of the securities at
the balance sheet date, and (iii) customer retentions, subcontract retentions
and customer advances estimated by discounting expected cash flows at rates
currently available to the Corporation for instruments with similar risks and
maturities.

               deposit promptly upon

               receipt and hold all amounts received by the Corporation in
               respect of refunds of federal income tax and interest thereon
               associated with amended federal income tax returns of the
               Corporation and consolidated subsidiaries for the calendar years
               1982 through 1990 which were filed prior to January 1, 1996,
               which change the Corporation's election from deducting foreign
               taxes to claiming a credit for those taxes ("Foreign Tax Credit
               Refunds"); provided, however, that the cumulative total amount of
               Foreign Tax Credit Refunds, together with any amounts contributed
               pursuant to the sentence prior to the penultimate sentence of
               this paragraph, which the Corporation may deposit to the Sinking
               Fund shall not exceed $18,000,000. A majority of the directors of
               the Corporation present at a meeting at which a quorum is present
               has the exclusive power and authority to determine, in good
               faith, on the basis of information known to them after reasonable
               inquiry, (i) whether funds received by the Corporation are
               Foreign Tax Credit Refunds and (ii) the amount of any Foreign Tax
               Credit Refunds. The holders of the Series A Preferred Stock shall
               have no right to challenge any such determination unless such
               challenge is specifically authorized by the beneficial owners of
               a majority of the issued and outstanding shares of the Series A
               Preferred Stock. The Corporation may, but shall not be obligated
               to, deposit funds other than Foreign Tax Credit Refunds into the
               Foreign Tax Credit Sinking Fund; provided, however, that such a
                                                --------  -------             
               deposit of funds other than Foreign Tax Credit Refunds shall be
               made only upon the affirmative vote of two-thirds of the total
               number of directors that the Corporation would have if there were
               no vacancies.  Pending distribution of the amounts in the Foreign
               Tax Credit Sinking Fund pursuant to paragraph (b)(iv)(B) of this
               Section 2, all such amounts shall be

               deposited into and maintained in an interest-bearing account at a
               bank or other depository institution at which the Corporation
               maintains other interest-bearing deposit accounts. Other than
               distributions made pursuant to paragraph (b)(iv)(B) of this
               Section 2, the Corporation shall not withdraw any funds from the
               Foreign Tax Credit Sinking Fund.

                    (B)    On the fifteenth day of the month following the end
               of each calendar quarter, the Corporation shall distribute to
               each holder of record of Series A Preferred Stock as of the last
               day of such calendar quarter an amount per share equal to a pro
               rata portion of (i) the total amount of Foreign Tax Credit
               Refunds deposited into the Foreign Credit Sinking Fund during the
               quarter and (ii) all interest earned on such total amount during
               the quarter. The distribution for the calendar quarter in which
               the cumulative total deposits to the sinking fund reaches
               $18,000,000 will be the final distribution with respect to the
               Series A Preferred Stock. Upon this final distribution, all
               shares of Series A Preferred Stock will be canceled and no longer
               outstanding and will not have the status of shares of Series A
               Preferred Stock, and all rights of the holders thereof as
               stockholders of the Corporation will cease.

                    (C)    If the Series A Preferred Stock has not been canceled
               as provided in paragraph (b)(iv)(B) of this Section 2 by the
               fifth anniversary of the issuance of the Series A Preferred
               Stock, the Corporation shall, on the fifteenth day ("Redemption
               Date") of the month following the fifth anniversary of the
               issuance of the Series A Preferred Stock, redeem all the
               outstanding shares of Series A Preferred Stock at a per share
               redemption price ("Redemption Price") equal to the greater of (I)
               $0.01, or (II) a pro rata portion of the balance of the Foreign
               Tax

               as of the fifth anniversary of the issuance of the Series A
               Preferred Stock.

                    (D)    In the event that the Corporation redeems shares of
               Series A Preferred Stock pursuant to paragraph (b)(iv)(C) of this
               Section 2, the Corporation shall send notice of the redemption by
               first-class mail, postage prepaid, not less than 30 days prior to
               the Redemption Date, to the holders of record of the shares to be
               redeemed at their respective addresses as they shall appear in
               the records of the Corporation; provided, however, that failure

               to give such notice or any defect therein or in the mailing
               thereof shall not affect the validity of the proceedings for the
               redemption of any shares so to be redeemed except as to the
               holder to whom the Corporation has failed to give such notice or
               except as to the holder to whom notice was defective.  Each such
               notice shall state:  (i) the Redemption Date; (ii) the number of
               shares of Preferred Stock to be redeemed; (iii) the Redemption
               Price, and (iv) the place or places where certificates for such
               shares are to be surrendered for payment of the Redemption Price.
               Upon surrender of the certificates for the shares (properly
               endorsed or assigned for transfer, if the Board of Directors so
               requires and a notice by the Corporation so states), the
               Corporation shall redeem such shares at the Redemption Price as
               aforesaid.

                    (E)    If the Corporation has mailed the notice provided in
               paragraph (b)(iv)(D) of this Section 2, then, from and after the
               Redemption Date (unless the Corporation defaults in the payment
               of the Redemption Price, in which case such rights shall continue
               until the Redemption Price is paid), all shares of Series A
               Preferred Stock will be deemed to be cancelled and no longer
               outstanding, and will not have the status of shares of Series A
               Preferred Stock, and all rights of the 

                                       7
<PAGE>
 
               holders thereof as stockholders of the Corporation (except the
               right to receive the Redemption Price) will cease.

               (v)   Liquidation Preference.
                     ---------------------- 

                     (A)   In the event of any voluntary or involuntary
               liquidation, dissolution or winding up of the affairs of the
               Corporation, each holder of outstanding shares of Series A
               Preferred Stock will be entitled to be paid out of the assets of
               the Corporation available for distribution to its stockholders,
               before any payment is made or any assets distributed to the
               holders of any of the Junior Securities, an amount in cash per
               share of Series A Preferred Stock held equal to the greater of
               (I) $0.01, or (II) a pro rata portion of the remaining balance of
               the Foreign Tax Credit Sinking Fund (including all interest
               earned thereon).  If the assets of the Corporation are not
               sufficient to pay in full the liquidation payments payable to the
               holders of outstanding shares of the Series A Preferred Stock and
               any Parity Securities, then the holders of all such shares shall
               share ratably in such distribution of assets in accordance with
               the amount which would be payable on such distribution if the
               amounts to which the holders of outstanding shares of Series A
               Preferred Stock and the holders of outstanding shares of such
               Parity Securities are entitled were paid in full.

                     (B)   For the purposes of this paragraph (b)(v), neither
               the voluntary sale, conveyance, exchange or transfer (for cash,
               shares of stock, securities or other consideration) of all or
               substantially all of the property or assets of the Corporation
               nor the consolidation or merger of the Corporation with any one
               or more other corporations shall be deemed to be a voluntary or
               involuntary liquidation, dissolution or winding up of the
               Corporation, unless such voluntary sale, 

                                       8
<PAGE>
 
               conveyance, exchange or transfer shall be in connection with a
               plan of liquidation, dissolution or winding up of the
               Corporation.

               (vi)   Reacquired Shares.  Shares of Series A Preferred Stock 
                      ----------------- 
          that have been issued and reacquired by the Corporation in any manner,
          including shares reacquired by redemption pursuant to paragraph
          (b)(iv) of this Section 2, shall (upon compliance with any applicable
          provisions of the laws of the State of Delaware) have the status of
          authorized and unissued shares of Preferred Stock undesignated as to
          series, and may be redesignated and reissued as part of any series of
          Preferred Stock.

               (vii)  Voting Rights.  In addition to any voting rights provided
                      -------------                                            
          by law, the holders of Series A Preferred Stock have the following
          voting rights:

                     (A)   General.  Except as required in this Article IV and 
                           -------                              
               as otherwise required by law, shares of Series A Preferred Stock
               shall vote together with shares of Common Stock of the
               Corporation as a single class on all matters as to which the
               shares of Common Stock are entitled to vote generally.  Each
               share of Series A Preferred Stock is entitled to 1/10,000 of a
               vote.

                     (B)   Voting Rights On Extraordinary Matters.  In 
                           --------------------------------------  
               addition to any vote or consent of stockholders required by law,
               the approval of holders of at least two-thirds of the outstanding
               shares of Series A Preferred Stock, voting as a class, is
               required (i) to reclassify any series of Junior Securities as
               Senior Securities or Parity Securities, or (ii) to amend, repeal
               or change any of the provisions of this Restated and Amended
               Certificate of Incorporation or the provisions of this Article IV
               in any manner that would alter or change the rights, powers,
               preferences or privileges of the shares of Series A Preferred
               Stock so as to affect them adversely, including, without
               limitation, changing the voting percentage 

                                       9
<PAGE>
 
               required for approval by the holders of Series A Preferred Stock
               of the foregoing matters.

                                  ARTICLE V.

          The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors, which shall consist of not less
than six directors nor more than 12 directors, the exact number of directors to
be determined from time to time by resolution adopted by the Board of Directors.
At each annual meeting of the stockholders of the Corporation, commencing with
the 1998 annual meeting, all directors will be elected to serve for a term
expiring at the next annual meeting of the stockholders of the Corporation.  A
director shall hold office until the annual meeting at which his or her term
expires and until his or her successor shall be elected and shall qualify,
subject, however, to prior death, resignation, retirement, disqualification or
removal from office.  Any vacancy on the Board of Directors, howsoever
resulting, may be filled by a majority of the directors then in office, even if
less than a quorum, or by a sole remaining director.  Any director elected to
fill a vacancy shall hold office for a term expiring at the next annual meeting
of the stockholders of the Corporation.  Notwithstanding anything to the
contrary in this Restated and Amended Certificate of Incorporation or any
provision of Bylaws of the Corporation, there shall be no cumulative voting.

                                  ARTICLE VI.

          Any or all of the directors of the Corporation may be removed from the
Board of Directors, with or without cause, by the affirmative vote of the
holders of a majority of the voting power of the outstanding shares of voting
stock of the Corporation entitled to vote thereon.

                                       10
<PAGE>
 
                                 ARTICLE VII.

          Elections of directors at an annual or special meeting of stockholders
need not be by written ballot unless the Bylaws of the Corporation shall
otherwise provide.

                                 ARTICLE VIII.

          Special meetings of the stockholders of the Corporation for any
purpose or purposes may be called at any time only by a majority of the Board of
Directors or the Chief Executive Officer or the President.

                                  ARTICLE IX.

          Any action which may be taken by stockholders of the Corporation at an
annual or special meeting may not be effected except at such an annual or
special meeting by the vote required for the taking of such action, and the
right of stockholders to act by written consent is expressly denied.

                                  ARTICLE X.

          The officers of the Corporation shall be chosen in such a manner,
shall hold their offices for such terms and shall carry out such duties as are
determined by the Board of Directors, subject to the right of the Board of
Directors to remove any officer or officers at any time with or without cause.

                                  ARTICLE XI.

          A.  The Corporation shall indemnify to the full extent authorized or
permitted by law (as now or hereafter in effect) any person made, or threatened
to be made, a defendant or witness to any action, suit or proceeding (whether
civil or criminal or otherwise) by reason of the fact that he, his testator or
intestate, is or was a director or officer of the Corporation or by reason of
the fact that such director or officer, at the request of the Corporation, is or
was serving any other corporation, partnership, joint 

                                       11
<PAGE>
 
venture, employee benefit plan or other enterprise, in any capacity. Nothing
contained herein shall affect any rights to indemnification to which employees
other than directors or officers may be entitled by law. No amendment or repeal
of this Section A of Article XI shall apply to or have any effect on any right
to indemnification provided hereunder with respect to any acts or omissions
occurring prior to such amendment or repeal.

          B.    No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty by such a director as a director.  Notwithstanding the foregoing sentence,
a director shall be liable to the extent provided by applicable law (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the
GCL, or (iv) for any transaction from which such director derived an improper
personal benefit.  No amendment to or repeal of this Section B of this Article
XI shall apply to or have any effect on the liability or alleged liability of
any director of the Corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment or repeal.

          C.    In furtherance and not in limitation of the powers conferred by
statute:

          (i)   the Corporation may purchase and maintain insurance on behalf of
     any person who is or was a director, officer, employee or agent of the
     Corporation, or is serving at the request of the Corporation as a director,
     officer, employee or agent of another corporation, partnership, joint
     venture, trust, employee benefit plan or other enterprise against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the Corporation would
     have the power to indemnify him against such liability under the provisions
     of law; and

          (ii)  the Corporation may create a trust fund, grant a security
     interest and/or use other means (including, without limitation, letters of
     credit, surety bonds and/or other similar 

                                       12
<PAGE>
 
     arrangements), as well as enter into contracts providing indemnification to
     the full extent authorized or permitted by law and including as part
     thereof provisions with respect to any or all of the foregoing to ensure
     the payment of such amounts as may become necessary to effect
     indemnification as provided therein, or elsewhere.

                                 ARTICLE XII.

          In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, repeal, alter,
amend or rescind the Bylaws of the Corporation.  In addition, the Bylaws of the
Corporation may be adopted, repealed, altered, amended, or rescinded by the
affirmative vote of two-thirds of the issued and outstanding stock of the
Corporation entitled to vote thereon.

                                 ARTICLE XIII.

          The Corporation reserves the right to repeal, alter amend, or rescind
any provision contained in this Restated and Amended Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred on stockholders herein are granted subject to this reservation.
Notwithstanding any other provision of this Restated and Amended Certificate of
Incorporation and any provisions of the Bylaws of the Corporation, any proposal
to amend or repeal Articles V, VI, VIII, IX, or XII, or this Article XIII or any
other proposal to amend this Restated and Amended Certificate of Incorporation
that is inconsistent with any provisions of Articles V, VI, VIII, IX, or XII or
this Article XIII shall require not less than the affirmative vote of two-thirds
of the issued and outstanding stock of the Corporation entitled to vote thereon.

                                 ARTICLE XIV.

                                       13
<PAGE>
 
          The Corporation will not issue nonvoting equity securities to the
extent prohibited by Section 1123 of the United States Bankruptcy Code;
provided, however, that this Article XIV (a) will have no further force and
effect beyond that required under Section 1123 of the United States Bankruptcy
Code, (b) will have such force and effect, if any, only for so long as such
Section 1123 is in effect and applicable to the Corporation, and (c) in all
events may be amended or eliminated in accordance with applicable law as from
time to time in effect.

                         MORRISON KNUDSEN CORPORATION
 
                             (AS OF APRIL 8, 1998)

                                    OFFICES
                                    -------

          Section 1.  REGISTERED OFFICES .  The registered office shall be in
the City of Dover, County of Kent, State of Delaware.

          Section 2.  OTHER OFFICES .  The corporation may also have offices at
such other places both within and without the State of Delaware as the Board of
Directors may from time to time determine or the business of the corporation may
require.

                                  ARTICLE II

                           MEETINGS OF STOCKHOLDERS
                           ------------------------

          Section 1.  PLACE OF MEETINGS .  Meetings of stockholders shall be
held at any place within or outside the State of Delaware designated by the
Board of Directors.  In the absence of any such designation, stockholders'
meetings shall be held at the principal executive office of the corporation.

          Section 2.  ANNUAL MEETING OF STOCKHOLDERS .  The annual meeting of
stockholders shall be held on such date and at such time and place as may be
fixed by the Board of Directors and stated in the notice of the meeting, for the
purposes of electing directors and for the transaction of such other business as
is properly brought before the meeting in accordance with these Bylaws.

          To be properly brought before the annual meeting, business must be
either (i) specified in the annual notice of meeting (or any supplement or
amendment thereto) given by or at the direction of the Board of Directors, (ii)
otherwise brought before the annual meeting by or at the direction of the Board
of Directors, or (iii) otherwise brought before the annual meeting by a
stockholder. In addition to any other applicable requirements, for business to
be brought before an annual meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the corporation. To
be timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the corporation, not less than fifty (50)
days nor more than seventy-five (75) days prior to the meeting; provided,
however, that in the event that less than sixty-five (65) days' notice or prior
public disclosure of the date of the annual meeting is given or made to
stockholders, notice by a stockholder to be timely must be so received not later
than the close of business on the fifteenth (15th) day following the day on
which such notice of the date of the annual meeting was mailed or such public
disclosure was made, whichever
<PAGE>
 
first occurs. A stockholder's notice to the Secretary shall set forth (a) as to
each matter the stockholder proposes to bring before the annual meeting (i) a
brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (ii)
the name and record address of the stockholder proposing such business, (iii)
the class, series and number of shares of the corporation which are beneficially
owned by the stockholder, and (iv) any material interest of the stockholder in
such business and (b) as to the stockholder giving the notice (i) the name and
record address of the stockholder and (ii) the class and number of shares of
capital stock of the corporation which are beneficially owned by the
stockholder. Notwithstanding anything in the Bylaws to the contrary, no business
shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Article II, Section 2. The officer of the
corporation presiding at an annual meeting shall, if the facts warrant,
determine and declare to the annual meeting that business was not properly
brought before the annual meeting in accordance with the provisions of this
Article II, Section 2, and if he should so determine, he shall so declare to the
annual meeting and any such business not properly brought before the meeting
shall not be transacted. Written notice of the annual meeting stating the place,
date and hour of the annual meeting shall be given to each stockholder entitled
to vote at such meeting not less than ten (10) nor more than sixty (60) days
before the date of the meeting.

          Section 3.  QUORUM; ADJOURNED MEETINGS AND NOTICE THEREOF .  A
majority of the stock issued and outstanding and entitled to vote at any meeting
of stockholders, the holders of which are present in person or represented by
proxy, shall constitute a quorum for the transaction of business except as
otherwise provided by law, by the Certificate of Incorporation, or by these
Bylaws.  A quorum, once established, shall not be broken by the withdrawal of
enough votes to leave less than a quorum and the votes present may continue to
transact business until adjournment.  If, however, such quorum shall not be
present or represented at any meeting of the stockholders, a majority of the
voting stock represented in person or by proxy may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
shall be present or represented.  At such adjourned meeting at which a quorum
shall be present or represented, any business may be transacted which might have
been transacted at the meeting as originally notified.  If the adjournment is
for more than thirty days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote thereat.

          Section 4.  VOTING .  When a quorum is present at any meeting, the
vote of the holders of a majority of the stock having power present in person or
represented by proxy at the meeting and entitled to vote on the subject matter
shall decide any question brought before such meeting, unless the question is
one upon which by express provision of the statutes, or the Certificate of
Incorporation or these Bylaws, a different vote is required in which case such
express provisions shall govern and control the decision of such question.
Directors of the corporation shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of directors.  Shares represented by proxies that reflect,
with respect to a proposal, abstentions or limited voting authority, including
"broker non-votes" (i.e., shares held by a broker or nominee which are
represented at the meeting, but with respect to which such broker or nominee is
not empowered to vote on a particular proposal or proposals) shall be counted as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum.  For purposes of determining the outcome of any proposal,
shares represented by such proxies will be treated as not present and not
entitled to vote with respect to the proposal or proposals.

          Section 5.  PROXIES .  At each meeting of the stockholders, each
stockholder having the right to vote may vote in person or may authorize another
person or persons to act for him by proxy appointed by an instrument in writing
subscribed by such stockholder and bearing a date not more than three years
prior to said meeting, unless said instrument provides for a longer period.  All
proxies must be filed with the Secretary of the corporation at the beginning of
each meeting in order to be counted in any 

                                       2
<PAGE>
 
vote at the meeting. Each stockholder shall have one vote for each share of
stock having voting power, registered in his name on the books of the
corporation on the record date set by the Board of Directors as provided in
Article VI, Section 6 hereof. All elections shall be had and all questions
decided by a plurality vote.

          Section 6.  SPECIAL MEETINGS .  Special meetings of the stockholders,
for any purpose, or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called only by a majority of the Board of
Directors or the Chief Executive Officer or the President.  Business transacted
at any special meeting of stockholders shall be limited to the purposes stated
in the notice.

          Section 7.  NOTICE OF STOCKHOLDERS' MEETINGS .  Whenever stockholders
are required or permitted to take any action at a meeting, a written notice of
the meeting shall be given which notice shall state the place, date and hour of
the meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.  The written notice of any meeting shall be given
to each stockholder entitled to vote at such meeting not less than 10 (ten) nor
more than 60 (sixty) days before the date of the meeting.  If mailed, notice is
given when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.

          Section 8.  MAINTENANCE AND INSPECTION OF STOCKHOLDER LIST .  The
officer who has charge of the stock ledger of the corporation shall prepare and
make, at least 10 (ten) days before every meeting of stockholders, a complete
list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 (ten) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

          Section 9.  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING .
Any action which may be taken by stockholders of the corporation at an annual or
special meeting may not be effected except at such an annual or special meeting
by the vote required for the taking of such action, and the right of
stockholders to act by written consent is expressly denied.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

          Section 1. THE NUMBER OF DIRECTORS . The number of directors which
shall constitute the whole Board shall be not less than six (6) directors nor
more than twelve (12) directors, the exact number of directors to be determined
from time to time by resolutions adopted by the Board of Directors. The exact
number of directors shall be nine (9) until changed as provided in this Section
1. The directors need not be stockholders. Only persons who are nominated in
accordance with the following procedures shall be eligible for election as
directors. Nominations of persons for election to the Board of Directors of the
corporation at the annual meeting may be made at such meeting by or at the
direction of the Board of Directors, by any committee or persons appointed by
the Board of Directors or by any stockholder of the corporation entitled to vote
for the election of directors at the meeting who complies with the notice
procedures set forth in this Article III, Section 1. Such nominations by any
stockholder shall be made pursuant to timely notice in writing to the Secretary
of the corporation. To be timely, a stockholder's notice shall be delivered to
or mailed and received at the principal executive offices of the corporation not

                                       3
<PAGE>
 
less than fifty (50) days nor more than seventy-five (75) days prior to the
meeting; provided, however, that in the event that less than sixty-five (65)
days notice or prior to public disclosure of the date of the meeting is given or
made to stockholders, notice by the stockholder to be timely must be so received
not later than the close of business of the fifteenth (15th) day following the
day on which such notice of the date of the meeting was mailed or such public
disclosure was made, whichever first occurs. Such stockholder's notice to the
Secretary shall set forth (i) as to each person whom the stockholder proposes to
nominate for election or reelection as a director, (a) the name, age, business
address and residence address of the person, (b) the principal occupation or
employment of the person, (c) the class and number of shares of capital stock of
the corporation which are beneficially owned by the person, and (d) any other
information relating to the person that is required to be disclosed in
solicitations for proxies for election of directors pursuant to the Rules and
Regulations of the Securities and Exchange Commission under Section 14 of the
Securities Exchange Act of 1934, as amended; and (ii) as to the stockholder
giving the notice (a) the name and record address of the stockholder and (b) the
class and number of shares of capital stock of the corporation which are
beneficially owned by the stockholder. The corporation may require any proposed
nominee to furnish such other information as may reasonably be required by the
corporation to determine the eligibility of such proposed nominee to serve as a
director of the corporation. No person shall be eligible for election as a
director of the corporation unless nominated in accordance with the procedures
set forth herein. The officer of the corporation presiding at an annual meeting
shall, if the facts warrant, determine and declare to the meeting that a
nomination was not made in accordance with the foregoing procedure, and if he
should so determine, he shall so declare to the meeting and the defective
nomination shall be disregarded. The directors shall be elected at the annual
meeting of the stockholders, except as provided in Section 2 of this Article
III, and each director elected shall hold office until his successor is elected
and qualified; provided, however, that unless otherwise restricted by the
Certificate of Incorporation or by law, any director or the entire Board of
Directors may be removed from the Board of Directors with or without cause at
any meeting of stockholders by a majority of the stock represented and entitled
to vote thereat.


          Section 2.  VACANCIES .  Vacancies on the Board of Directors by reason
of death, resignation, retirement, disqualification, removal from office, or
otherwise, and newly created directorships resulting from any increase in the
authorized number of directors may be filled by a majority of the directors then
in office, although less than a quorum, or by a sole remaining director.  The
directors so chosen shall hold office for a term that shall coincide with the
term of the class to which such director shall have been elected.  If there are
no directors in office, then an election of directors may be held in the manner
provided by statute.  If, at the time of filling any vacancy or any newly
created directorship, the directors then in office shall constitute less than a
majority of the whole Board (as constituted immediately prior to any such
increase), the Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent of the total number of the shares at
the time outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office.

          Section 3.  POWERS .  The property and business of the corporation
shall be managed by or under the direction of its Board of Directors.  In
addition to the powers and authorities by these Bylaws expressly conferred upon
them, the Board may exercise all such powers of the corporation and do all such
lawful acts and things as are not by statute or by the Certificate of
Incorporation or by these Bylaws directed or required to be exercised or done by
the stockholders.

          Section 4.  PLACE OF DIRECTORS' MEETINGS .  The directors may hold
their meetings and have one or more offices, and keep the books of the
corporation outside of the State of Delaware.

                                       4
<PAGE>
 
          Section 5.  MEETINGS .  The Board of Directors of the corporation may
hold meetings, both regular and special, either within or without the State of
Delaware.  Regular meetings of the Board of Directors may be held without notice
at such time and at such place as may from time to time be determined by the
Board of Directors.  Special meetings of the Board of Directors may be called by
the Chairman of the Board of Directors, the President, or by a majority of the
Board of Directors.  Notice thereof, stating the place, date and hour of the
meeting, shall be given to each director either by mail not less than four (4)
days before the date of the meeting, or personally or by telephone, telegram,
telex or similar means of communication on twelve (12) hours' notice, or on such
shorter notice as the person or persons calling such meeting may deem necessary
or appropriate in the circumstances.

          Section 6.  QUORUM .  At all meetings of the Board of Directors a
majority of the authorized number of directors shall be necessary and sufficient
to constitute a quorum for the transaction of business, and the vote of a
majority of the directors present at any meeting at which there is a quorum,
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute, by the Certificate of Incorporation or by
these Bylaws.  If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.  If only one director is authorized, such sole director shall
constitute a quorum.

          Section 7.  ACTION WITHOUT MEETING .  Unless otherwise restricted by
the Certificate of Incorporation or these Bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.

          Section 8.  TELEPHONIC MEETINGS .  Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, members of the Board of Directors,
or any committee designated by the Board of Directors, may participate in a
meeting of the Board of Directors, or any committee, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at such meeting.

          Section 9.  COMMITTEES OF DIRECTORS .  The Board of Directors may, by
resolution passed by a majority of the whole Board, designate one or more
committees, each such committee to consist of one or more of the directors of
the corporation.  The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee.  In the absence or disqualification of a member of
a committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board of Directors,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to the following matters: (i) approving or adopting, or recommending to the
stockholders, any action or matter expressly required by the Delaware General
Corporation Law to be submitted to stockholders for approval or (ii) adopting,
amending or repealing any bylaw of the corporation.

          Section 10.  MINUTES OF COMMITTEE MEETINGS .  Each committee shall
keep regular minutes of its meetings and report the same to the Board of
Directors when required.

<PAGE>
 
          Section 11. COMPENSATION OF DIRECTORS .  Unless otherwise restricted
by the Certificate of Incorporation or these Bylaws, the Board of Directors
shall have the authority to fix the compensation of directors.  The directors
may be paid their expenses, if any, of attendance at each meeting of the Board
of Directors and may be paid a fixed sum for attendance at each meeting of the
Board of Directors or a stated salary as director. No such payment shall
preclude any director from serving the corporation in any other capacity and
receiving compensation therefor.  Members of special or standing committees may
be allowed like compensation for attending committee meetings.

                                ARTICLE IV

                                OFFICERS

          Section 1.  OFFICERS .  The principal officers of this corporation

there are two or more Vice Presidents, then one or more may be designated as
Executive Vice President, Senior Vice President, or other similar or dissimilar
title.  At the time of the election of officers, the directors may by resolution
determine the order of their rank.  Any number of offices may be held by the
same person, unless the Certificate of Incorporation or these Bylaws otherwise
provide.  The Board of Directors may also appoint a Chairman of the Board who
need not be an officer of the corporation unless specifically designated as such
by the Board.

          Section 2.  ELECTION OF OFFICERS .  The Board of Directors, at its
first meeting after each annual meeting of stockholders, shall choose the

appoint such other subordinate officeholders and agents as it shall deem
necessary who shall hold their offices for such terms and shall exercise such

Board.  The Chief Executive Officer may also from time to time appoint
subordinate officeholders, who shall not be corporate officers, to such
positions, with such limited authority and such titles, as the Chief Executive
Officer may determine.  Subordinate officeholders shall hold office for such
period, and have such authority and title, and perform such duties as may be
designated by the Chief Executive Officer, provided, that such subordinate
officeholders shall not have or perform authorities or duties co-extensive with
the authorities or duties of principal or subordinate officers chosen by the
Board of Directors.

                                   ARTICLE V

                         INDEMNIFICATION OF DIRECTORS,
                         -----------------------------
                        OFFICERS, EMPLOYEES AND AGENTS
                        ------------------------------

          (a) The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

          (b) The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, 

                                       8
<PAGE>
 
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and except that no such indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the corporation unless and only to the extent
that the Court of Chancery of Delaware or the court in which such action or suit
was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such Court
of Chancery or such other court shall deem proper.

          (c) To the extent that a director, officer, employee or agent of the
corporation shall be successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

          (d) Any indemnification under paragraphs (a) and (b) (unless ordered
by a court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper under the circumstances because he has met the
applicable standard of conduct set forth in paragraphs (a) and (b).  Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (3) by the stockholders.

          (e) Expenses (including attorneys' fees) incurred by an officer or
director in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the corporation as authorized in this Article V.  Such expenses (including
attorneys' fees) incurred by other employees and agents may be so paid upon such
terms and conditions, if any, as the Board of Directors deems appropriate.

          (f) The indemnification and advancement of expenses provided by, or
granted pursuant to, the other paragraphs of this Article V shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

          (g) The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the provisions of this Article V.

          (h) For the purposes of this Article V, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any

person who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Article V with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

          (i) For purposes of this section, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include service
as a director, officer, employee or agent of the corporation which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants or beneficiaries; and
a person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the corporation" as referred to in this section.

          (j) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article V shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

          (k) The corporation shall be required to indemnify a person in
connection with a proceeding (or part thereof) initiated by such person only if
the proceeding (or part thereof) was authorized by the Board of Directors of the
corporation.

                                  ARTICLE VI

                             CERTIFICATES OF STOCK
                             ---------------------

          Section 1.  CERTIFICATES .  Every holder of stock of the corporation
shall be entitled to have a certificate signed by, or in the name of the
corporation by, the Chairman of the Board of Directors, if the Board has
appointed one, or the President or a Vice President, and by the Secretary or an
Assistant Secretary, or the Treasurer or an Assistant Treasurer of the
corporation, certifying the number of shares represented by the certificate
owned by such stockholder in the corporation.

          Section 2.  SIGNATURES ON CERTIFICATES .  Any or all of the signatures
on the certificate may be a facsimile.  In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar
before such certificate is issued, it may be issued by the corporation with the
same effect as if he were such officer, transfer agent, or registrar at the date
of issue.

          Section 3.  STATEMENT OF STOCK RIGHTS, PREFERENCES, PRIVILEGES .  If
the corporation shall be authorized to issue more than one class of stock or
more than one series of any class, the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualification, limitations or restrictions of such
preferences and/or rights shall be set forth in full or summarized on the face
or back of the certificate which the corporation shall issue to represent such
class or series of stock, provided that, except as otherwise provided in Section
202 of the General Corporation Law of Delaware, in lieu of the foregoing
requirements, there may be set forth on the face or back of the certificate
which the corporation shall issue to represent such class or series of stock, a
statement that the corporation will furnish without charge to each stockholder
who so requests the powers, designations, preferences and relative,
participating, optional or other special rights 

                                      10
<PAGE>
 
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights.

          Section 4.  LOST CERTIFICATES .  The Board of Directors may direct a
new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed.  When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the corporation a bond in such sum as it may
direct as indemnity against any claim that may be made against the corporation
with respect to the certificate alleged to have been lost, stolen or destroyed.

          Section 5.  TRANSFERS OF STOCK .  Upon surrender to the corporation,
or the transfer agent of the corporation, of a certificate for shares duly
endorsed or accompanied by proper evidence of succession, assignation or
authority to transfer, it shall be the duty of the corporation to issue a new
certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

          Section 6.  FIXED RECORD DATE .  In order that the corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
the stockholders, or any adjournment thereof, or entitled to receive payment of
any dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix a
record date which shall not be more than 60 (sixty) nor less than 10 (ten) days
before the date of such meeting, nor more than 60 (sixty) days prior to any
other action.  A determination of stockholders of record entitled to notice of
or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.

          Section 7.  REGISTERED STOCKHOLDERS .  The corporation shall be
entitled to treat the holder of record of any share or shares of stock as the
holder in fact thereof and accordingly shall not be bound to recognize any
equitable or other claim or interest in such share on the part of any other
person, whether or not it shall have express or other notice thereof, save as
expressly provided by the laws of the State of Delaware.


                                  ARTICLE VII

available for dividends such sum or sums as the directors from time to time, in
their absolute discretion, think proper as a reserve fund to meet contingencies,
or for equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the directors shall think conducive to
the interests of the corporation, and the directors may abolish any such
reserve.

Directors may from time to time designate.

          Section 6.  MANNER OF GIVING NOTICE .  Whenever, under the provisions
of the statutes or of the Certificate of Incorporation or of these Bylaws,
notice is required to be given to any director or stockholder, it shall not be
construed to mean personal notice, but such notice may be given in writing, by
mail, addressed to such director or stockholder, at his address as it appears on
the records of the corporation, with postage thereon prepaid, and such notice
shall be deemed to be given at the time when the same shall be deposited in the
United States mail.  Notice to directors may also be given by telegram.

          Section 7.  WAIVER OF NOTICE .  Whenever any notice is required to be
given under the provisions of the statutes or of the Certificate of
Incorporation or of these Bylaws, a waiver thereof in writing, signed by the
person or persons entitled to said notice, whether before or after the time
stated therein, shall be deemed equivalent thereto.

          Section 8.  ANNUAL STATEMENT .  The Board of Directors shall present
at each annual meeting, and at any special meeting of the stockholders, a full
and clear statement of the business and condition of the corporation.


                                 ARTICLE VIII

                                  AMENDMENTS

          Section 1.  AMENDMENT BY DIRECTORS .  These Bylaws may be altered,
amended or repealed or new Bylaws may be adopted by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the Board of Directors or at any
special meeting of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new Bylaws be contained in the notice of such
special meeting.  If the power to adopt, amend or repeal Bylaws is conferred

divest or limit the power of the stockholders to adopt, amend or repeal Bylaws.

Mr. Robert A. Tinstman
President and Chief Executive Officer
Morrison Knudsen Corporation
Morrison Knudsen Plaza
720 Park Boulevard
Boise, Idaho  83712

Dear Bob:

     This is to confirm our understanding that Morrison Knudsen Corporation, its
successors and/or assignees (the "Company") has retained Batchelder & Partners,
Inc. ("B&P") as its non-exclusive financial advisor with respect to transactions
that the Company may pursue with CBS Corporation ("CBS"), including the merger,
consolidation, combination, reorganization, recapitalization or acquisition of
all or a portion of the stock or assets of CBS Corporation divisions known to
you and us as Government and Environmental Services Company ("GESCO"), and
Energy Systems ("Energy Systems") (individually or collectively a
"Transaction").  "You," as used herein, shall refer to the Company.

     In connection with our engagement hereunder and all other engagements
involving the Company and in effect during calendar year 1998, the Company shall
pay B&P an aggregate retainer fee of $50,000 per month, payable in cash on the
first business day of each month commencing April 1, 1998.  Provided, however,
that the maximum monthly, and aggregate retainer fee payable to B&P pursuant to
this agreement and pursuant to all other fee arrangements in effect during
calendar year 1998 between the Company and B&P shall not exceed $50,000, and
$250,000, respectively, for the twelve months ended December 31, 1998.  Provided
further that any retainer fee paid to B&P hereunder shall be creditable against
any Success Fee (as hereinafter defined) paid to B&P pursuant to this agreement
or pursuant to any other agreement entered into during 1998 between B&P and the
Company.

     Further, if any Transaction or series of Transactions is consummated by You
and/or any entity substantially owned by You or any partnership, limited
liability company, affiliate or joint venture of which You are a member (singly
or collectively, "Acquirer"), the Company agrees to pay B&P a fee (the "Success
Fee") equal to 0.6 percent (.006) of the MK Transaction Value.  "MK

Transaction Value" shall mean the aggregate Value (as hereinafter defined) of
all cash, non-cash assets, equity and debt issued or assumed in connection with
a Transaction and shall include the Value of equity and debt securities of any
entity created as part of a process to effect a Transaction.  "Value" shall mean
(i) with respect to cash, the amount thereof provided by You or accruing to the
Company's economic interest in Acquirer; (ii) with respect to marketable
securities contributed by You or accruing to the Company's economic interest in
Acquirer, the mean of the average of the bid and ask of such securities as
quoted at the close on their principal trading market on the tenth through the
sixth consecutive trading days ending on the trading day preceding the date of
closing of the Transaction or, if not quoted on such dates, the mean of the
average of the bid and ask of such  securities as quoted at the close on their
principal trading market on the five (5) consecutive trading days beginning with
the next such trading day on which a bid/ask is so quoted; and (iii) with
respect to non-cash consideration other than marketable securities, the fair
market value thereof relevant to the Company's economic interest in Acquirer as
mutually agreed by the Company and B&P.  Any fee pursuant to this paragraph
shall be payable in cash upon closing or consummation of such Transaction or, in
the event that the determination of Value requires market information only
available after such closing, as soon as practicable thereafter but in no event
later than fifteen (15) days after closing or consummation of such Transaction.
In the event that a Transaction is not consummated and the Company receives a
break fee or similar compensation (a "Break Fee"), the Company shall pay to B&P
ten (10) percent of such Break Fee.

     In addition to the foregoing compensation, You shall reimburse B&P for our
reasonable out-of-pocket expenses, which shall include the fees and
disbursements of our counsel.  We shall not incur expenses in excess of $25,000
without your approval, which shall not be unreasonably withheld.

     Since we will be acting on the Company's behalf, the Company is agreeing to
provide us with indemnification pursuant to the letter dated April 1, 1998 from
the Company to B&P.  Further, nothing in this engagement is intended to create
an agency or other fiduciary relationship between the parties or any of their
affiliates, directors, officers, partners, agents or employees.  The sole
obligation of B&P hereunder shall be the contractual obligations specifically
created by this agreement.

     Our services hereunder may be terminated by the Company or by B&P upon
written notice and, in any event, shall terminate on March 31, 1999.  If the
Company elects to terminate, no further retainer amounts shall accrue, any due
but unpaid retainer amounts and fees shall be paid and any reimbursable expenses
incurred before the date of termination shall be paid.  Provided, however,

Mr. Robert Tinstman                     -3-                       April 6, 1998


you specifically acknowledge that our services hereunder will have continuing
value to the Company and therefore You agree that if You terminate our services
and within 12 months thereafter, an Acquirer effects a Transaction, then B&P
shall be entitled to compensation pursuant to the third paragraph hereof to the
same extent as if our services had not been terminated.  If B&P elects to
terminate, no further retainer amounts shall accrue, any due but unpaid retainer
amounts and fees shall be paid and any reimbursable expenses incurred before the
date of termination shall be paid.  Notwithstanding the foregoing, the
provisions of the preceding paragraph shall survive any termination, whether by
the Company, or by B&P, as a result of the passage of time or otherwise.

     Except as required by law, any advise (written or oral) rendered by us
pursuant to this letter ay not be disclosed publicly without our prior written
consent, which consent shall not be unreasonably withheld.

     Please confirm that the foregoing is in accordance with the Company's
understanding by signing and returning the duplicate of this letter attached
hereto, which shall thereupon constitute a binding agreement.

                              Very truly yours,

Gentlemen:

     In connection with your engagement as financial advisor to Morrison Knudsen
Corporation, its successors and/or assignees (the "Undersigned") with respect to
the matters contemplated by the letter from you to the Undersigned of even date
herewith, the Undersigned hereby agrees to indemnify and hold harmless you and
your affiliates, the respective directors, officers, partners, agents, and
employees of you and your affiliates and each other person, if any, controlling
you or any of your affiliates, to the full extent lawful, from and against all
losses, claims, damages, liabilities and expenses incurred by you and such other
persons (including reasonable fees and disbursements of counsel) which (A) are
related to or arise out of (i) actions taken or omitted to be taken (including
any untrue statements made or any statements omitted to be made) by the
Undersigned, its associates or affiliates or (ii) actions taken or omitted to be
taken by an indemnified person with the consent of the Undersigned, its
associates or affiliates or in conformity with their actions or omissions or (B)
are otherwise related to or arise out of your activities on behalf of the
Undersigned, its associates or affiliates under your engagement, and the
Undersigned will reimburse you and any other person indemnified hereunder for
all expenses (including reasonable fees and disbursements of counsel) as they
are incurred by you or such other indemnified person in connection with
investigating, preparing or defending any such action or claim, whether or not
in connection with pending or threatened litigation in which you or any other
indemnified person is a party.  The Undersigned will not be responsible,
however, for any losses, claims, damages, liabilities or expenses pursuant to
clause (B) of the preceding sentence which are finally judicially determined to
have resulted primarily from the willful misconduct, bad faith or gross
negligence of the person seeking indemnification hereunder (although it is
expressly intended that the Undersigned will be responsible for any thereof that
result from the negligence, other than gross negligence, of such person).  The
Undersigned also agrees that neither you, nor any of your affiliates, nor any
director, officer, partner, agent or employee of you or any of your affiliates,
nor any person controlling you or any of your affiliates, shall have any
liability to the Undersigned for or in connection with such engagement except
for such liability for losses, claims, damages, liabilities or expenses incurred
by the Undersigned which is finally judicially determined to have resulted
primarily from your willful misconduct, bad faith or gross negligence as herein
described.  The foregoing agreement shall be in addition to any rights that you
or any indemnified person may have at common law or otherwise, including, but
not limited to, any right to contribution.

engaged to act for the Undersigned, its associates or affiliates in one or more
additional capacities, and that the terms of the original engagement or any such
additional engagement may be embodied in one or more separate written
agreements.  This indemnification shall apply to the original engagement, any
such additional engagement and any modification of the original engagement or
such additional engagement in connection with which this letter is expressly
referenced in writing and shall remain in full force and effect following the
completion or termination of such engagement(s).

          SECTION 2.4.  PURCHASE PRICE.  Subject to Section 2.5 and Section
                        --------------                                     
3(a)(iii)(B)(1) of Annex S, the purchase price for the Acquired Assets (the
"Purchase Price") shall consist of 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.  The Statement of Working
Capital shall become final and binding upon the parties on the 60/th/ 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 


                                      30
<PAGE>
 
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 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
                       -----------------------                               
$14,600,000.  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 


                                      31

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, including a proforma adjustment for
certain restructuring actions.  The terms "Total Current Assets" and "Total
                                           --------------------       -----
Current liabilities" shall mean the total current assets and total current
- -------------------                                                       
liabilities, respectively, of the Business (including amounts related to the
nuclear instrumentation and control business), 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) all warranty liabilities for
(x) RCCA (control rods), (y) fuel element structural corrosion or (z) rod
internal pressure, (v) deferred Income Taxes, (vi) all Steam Generator
Liabilities, (vii) 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 has 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 the loss prior to the
Closing would be an Acquired Asset, and (viii) any current assets and current
liabilities of STC, 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).


                                      32
<PAGE>
 
          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, government rate and cost disallowance liabilities, or Steam
Generator 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 (including amounts related to the nuclear
instrumentation and control business), 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 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 


                                      33
<PAGE>
 
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.

the Assumed Liabilities in form and substance reasonably satisfactory to CBS and
its counsel (it being understood that any such instrument in clause (ii) or

that are not otherwise expressly provided for in this Agreement).

          (C) NOMINEE SHARES.  At the Closing, or as promptly thereafter as

          (B) AUTHORITY.  CBS has the requisite corporate power and authority to

corporate power and authority to execute, deliver and perform the agreements to
be entered into by them at the Closing pursuant hereto (the "Seller Ancillary
                                                             ----------------
Documents") and to consummate the transactions contemplated hereby and thereby.
- ---------

on the part of CBS, and, in the case of the Seller Ancillary Documents, will be
authorized by all necessary corporate action on the part of the Selling

any of Sellers will be duly executed and delivered at the Closing and when so
executed and delivered will constitute, a legal, valid and binding obligation of
each of the Sellers party thereto enforceable against it in accordance with its

rise to a right of termination, cancellation or acceleration of any obligation
(except, to the extent provided in any such program or plan, any acceleration of
vesting under the Westinghouse Savings Program or under any Pension Plan or 
long-term incentive plan) or to the loss of a material benefit under, or result
in the creation of any Lien upon any of the Acquired Assets under, any provision
of (i) the Business Corporation Law of the Commonwealth of Pennsylvania, (ii)
the certificate of incorporation or by-laws (or comparable organizational
documents) of any of Sellers or the Sold Subsidiaries, (iii) except as disclosed
in Schedule 4.1(b)(i), any Intellectual Property, Technology, contract, lease,
indenture or other agreement of any Seller or Sold Subsidiary or (iv) subject to
the filings and other matters referred to in the following sentence, any Law
applicable to Sellers, the Sold Subsidiaries, the Acquired Assets or the
Subsidiary Assets, other than, in the case of clauses (iii) and (iv) above, any
such conflicts, violations, defaults, rights or Liens that, individually or in
the aggregate, would not (A) reasonably be expected to have a Material Adverse
Effect or (B) materially impair the ability of CBS 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 to be obtained or made by or with respect to Sellers, the
Sold Subsidiaries, the Acquired Assets or the Subsidiary Assets in connection
with the execution and delivery of this Agreement or the Seller Ancillary
Documents or the consummation of the transactions contemplated hereby or
thereby, except as disclosed in

opposed to any other Person's) participation in the transactions contemplated
hereby and (ix) those the failure of which to obtain or make, individually or in
the aggregate, would not (A) reasonably be expected to have a Material Adverse
Effect or (B) materially impair the ability of CBS to perform its obligations
under this Agreement.

          (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 in 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 in 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 


                                      37
<PAGE>
 
     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 $5,000,000 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 amount
     billed and uncollected with an invoice amount in excess of $500,000.

          (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 in 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 in
                -------------------------------                             
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 


                                      38
<PAGE>
 
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
contract or project. This Section 4.1(d) does not relate to litigation matters
(to which Section 4.1(e) is applicable), labor and employment matters (to which
Section 4.1(q) is applicable), employee benefits matters (to which Section
4.1(m) is applicable), Environmental Laws (to which Sections 4.1(j)(B) and
4.1(n) are applicable) or Tax matters (to which Section 4.1(o) is applicable).

          (ii) Except as set forth in Schedule 4.1(d)(ii), with respect to the
     Acquired 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 is a
party and which, if still pending on the Closing Date, would be an Assumed
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 $5,000,000.  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 


                                      39
<PAGE>
 
     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.

This Section 4.1(f) does not relate to Intellectual Property or Technology (to
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(c) 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 


                                      40
<PAGE>
 
     with the conveyance of the Owned Real Property to Purchaser. Except as set
     forth in Schedule 4.1(g)(i), 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(b) 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(b) or in a manner which would not reasonably be
     expected to materially reduce the benefits to Purchaser of the 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 


                                      41
<PAGE>
 
     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 in 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 in
     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 


                                      42
<PAGE>
 
     of any security interests. Except as set forth in 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 in 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 in 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 claim is still pending. Except as set forth in 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 in 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 the names
     and marks of CBS 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


                                      43

     sentence, nothing in this Agreement shall imply an indemnity for the
     infringement of third party intellectual property rights not within the
     knowledge of CBS.

The term "Material Contracts" also includes the 20 largest (measured by unfilled
order balance as of May 31, 1998 and prior to reduction for obligations under
Settlement Agreements) Contracts (including sales orders) involving the
obligation of Sellers or a Sold Subsidiary to deliver products or services. Such
Contracts are listed in Schedule 4.1(j)(A)(xvi). All of the Material Contracts
are (or in the case of the Material Contracts referred to in Schedule
4.1(j)(A)(xvi), were as of May 31, 1998) 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 


                                      46
<PAGE>
 
best knowledge of CBS, as of the date hereof, no other party to any such
Material Contract is in default in any 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. (S) 970.5204-31 (1997), (B) 48 C.F.R. (S) 970.5204-61
(1997), or (C) 48 C.F.R. (S) 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. (S) 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 in 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.

          (K) SUFFICIENCY OF ACQUIRED ASSETS.  Except as disclosed in Schedule

(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

                                      47
<PAGE>
 
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

     extent available, and (F) the most recent determination letter with respect

     Code.  Schedule 4.1(m)(i) also separately identifies each Benefit Plan
     covering only employees or Former Employees of the Business ("Free Standing
                                                                   -------------
     Plans").
     -----   

          (ii) Each Benefit Plan has been administered in all material respects
     in accordance with its terms and is in compliance in all material respects

     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 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

     in the United States ("U.S. Pension Plans"), and (C) no U.S. 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 U.S. Pension 
     Plans have been the subject of determination letters from the Internal
     Revenue Service to the effect that such U.S. 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 U.S. 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

     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 U.S. 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.

          (vi)   With respect to any U.S. 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 U.S. Pension Plan that is a defined benefit
     pension plan, there was not any amount of "unfunded benefit liabilities"

     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,

                -----                                          

          (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

     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

     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 Sellers (with respect
     to the Acquired Assets or the income or operation of the Business or the
     Sold Subsidiaries) has not filed Tax Returns that such Seller or Sold
     Subsidiary is or may have been subject to taxation by that jurisdiction.

          (viii) No power of attorney currently in force has been granted by
     any Seller (with respect to the Acquired Assets or the income or operation

     all material respects with the provisions of the Code relating to the
     payment and withholding of Taxes, including, without limitation, the
     withholding and reporting requirements under Code Sections 1441 through
     1464, 3401 through 3606, and 6041 and 6049, as well as similar provisions
     under any other Laws, and within the time and in the manner prescribed by

     employee, independent contractor, creditor, stockholder, or other third
     party.

          (xi)   No Sold Subsidiary (A) has filed a consent under Code Section

                 -----------------                                              
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 in Schedule 1.1(g), free and
clear of all Liens, except as set forth in Schedule 1.1(g). For purposes of this
Section 4.1(p), "beneficial ownership" of any shares of capital stock shall 


                                      55
<PAGE>
 
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(g), 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(g), 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(g), 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 or any similar body in any material foreign jurisdiction 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 in 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 


                                      56
<PAGE>
 
or Sold Subsidiary, would involve aggregate expenditures or receipts in excess
of $5,000,000. Other than with respect to Steam Generator Settlement Agreements,
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 AND CUSTOMERS.

          (i)  Schedule 4.1(s) sets forth:

          during the twelve-month period ending December 31, 1997); and

     (B)  the name of, and a brief description of the goods and services
          supplied to, the twenty largest customers of the Business (based upon

          occurred in the business relationship of the Sellers or the Sold
          Subsidiaries with any customer or supplier listed in 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 customer or supplier listed in Schedule
          4.1(s), to the effect that any such customer or supplier intends to
          cease, or make a material reduction in, its purchases of goods or
          services from, or 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.

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

     foregoing.

          (B)  ADVICE OF CHANGES.  CBS shall promptly notify Purchaser of:
               -----------------                                          

          (i)  any actions, suits, claims or proceedings or, to the knowledge of
     CBS, investigations commenced or, to its knowledge, threatened against CBS,
     its Subsidiaries or the Business that, if pending on the date of this
     Agreement, would have been required to have been disclosed pursuant to
     Section 4.1(e); and

          (ii) the damage or destruction by fire or other casualty of any
     material Acquired Asset or part thereof or in the event that any material

     taking thereof or any part thereof or of any right relating thereto by
     condemnation, eminent domain or other similar governmental action.

provided, however, that CBS shall have no Liability for breach of this Section
- --------  -------                                                             
5.1(b) except to the extent Purchaser has actually been prejudiced by such
breach.

          SECTION 5.2.  ACCESS TO INFORMATION; CONSULTATION.
                        ----------------------------------- 

          (a)  CBS shall afford to Purchaser and its accountants, counsel and
other representatives reasonable access at reasonable times during the period
prior to the Closing to all the properties, books, Contracts, commitments, Tax
Returns, pending bids and proposals for contracts the anticipated revenues from
which will exceed $25,000,000 (excluding contracts for which CBS believes
Purchaser or any of its Affiliates is a competing bidder), and records of the
Business (other than to the extent such information relates to the Excluded
Assets or Excluded Liabilities), and during such period shall furnish promptly
to Purchaser any information concerning the Business (other than to the extent
such information relates to the Excluded Assets or Excluded Liabilities) as
Purchaser may reasonably request and shall use reasonable commercial efforts on
a timely basis to obtain any counterparty or third-party consents necessary to
permit Purchaser access to such information; and shall cause its and the other
Sellers' officers, employees, consultants, agents, accountants and attorneys to
cooperate reasonably with Purchaser's representatives in connection with such
review and examination; provided, however, that CBS is under no obligation to
                        --------  -------                                    
disclose to Purchaser (i) any 


                                      63
<PAGE>
 
information the disclosure of which is restricted by applicable Law except in
strict compliance with the applicable Law, (ii) any information as to which the
attorney-client privilege, the attorney work-product doctrine or the self-
evaluative privilege may be available, except to the extent covered by the Joint
Defense Agreement referred to in Section 5.30 or, if not so covered, until a
mutually satisfactory joint defense agreement has been executed 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 NRC 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
Energy Systems Business 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 ESBU 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 Energy Systems Business (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 


                                      64
<PAGE>
 
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 Energy Systems Business
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, (ii) but in no event later than 20 business days following the execution
and delivery of this Agreement, (A) file with the Committee on Foreign
Investment in the United States the voluntary notification under the Exon-Florio
Amendment for the transactions contemplated hereby and (B) file with the NRC or
applicable Agreement States such applications for licenses or license transfers
as necessary 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 authorization of, or registration,
declaration or filing with, any Governmental Authority or any other Person in
connection with such trans  actions 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 


                                      65
<PAGE>
 
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 Govern  mental 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."  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 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, (P) 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, (P)
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.

          (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 


                                      67
<PAGE>
 
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.

          (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) and each
     STC Employee 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").  Each employee or former
                           -----------------                            
     employee who primarily rendered services on behalf of the Business or STC
     Employee 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
                                                                    ------

     offered active employment by Purchaser pursuant to the Recall Rights.  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 


                                      69

     employee of any Seller during such six-month period without the consent of
     such Seller (other than as provided 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 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

     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 and 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


                                      70

the Closing Date such schedules as CBS maintains and such other information as
reasonably necessary to calculate such benefits.

          (C)  UNION REPRESENTATION.  Purchaser agrees with respect to any
               --------------------                                       
collective bargaining agreement that relates to Business Employees, to (i)
recognize each union 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.

          (D)  PENSION PLAN.  (i)  Purchaser shall or shall cause its Affiliates
               ------------                                                     
to credit Business Employees with service with Sellers and Sold Subsidiaries for
purposes of eligibility, vesting and retirement eligibility under all pension
plans within the meaning of Section 3(2) of ERISA in which such Business
Employees participate.

          (ii) The WELCO Pension Plan shall retain liability with respect to
     Business Employees and Former Employees for their accrued benefit
     calculated as of the Closing Date, subject to adjustment as follows.  CBS
     shall take appropriate action to cause the WELCO Pension Plan to provide
     (x) credit for employment of Business Employees with the Purchaser or its
     Affiliates solely for purposes of calculating vesting credit and
     eligibility for early retirement benefits ("Eligibility Service," as
                                                 -------------------     
     defined in the WELCO Pension Plan), and (y) except as provided in (d)(iv)
     below, the early retirement supplement under Section 5 for Business
     Employees under the terms of the WELCO Pension Plan shall be equal to the
     lesser of -

     (A) the early retirement supplement calculated under the terms of the WELCO
     Pension Plan, or as it may be reduced by CBS after the Benefits Maintenance
     Period, but only to the extent such a change applies to all CBS employees
     with the same benefit, as multiplied by a fraction, the numerator of which
     is the participant's years of Credited Service (as defined in the WELCO
     Pension Plan) under the WELCO Pension Plan as of the Closing Date, and the
     denominator of which is the sum of the numerator and the participant's
     years of employment with the Purchaser and its Affiliates from the Closing
     Date until the participant's retirement or termination of employment with
     the Purchaser and its Affiliates, or


                                      71
<PAGE>
 
     (B) the comparable early retirement supplement calculated under the terms
     of the Purchaser defined benefit plan covering Business Employees
     ("Purchaser Pension Plan") as in effect on the participant's retirement or
     termination of employment from the Purchaser and its Affiliates (prior to
     reduction for the portion of the supplement to be paid from the WELCO
     Pension Plan) (if the Purchaser Pension Plan has no such supplement or if
     there is no Purchaser Pension Plan the amount calculated under this
     subparagraph (B) shall be zero (0)) multiplied by a fraction, the numerator
     of which is the employee's years of Credited Service under the WELCO
     Pension Plan as of the Closing Date, and the denominator of which is the
     sum of the numerator and the participant's years of employment with the
     Purchaser and its Affiliates from the Closing Date until the participant's
     termination of employment with the Purchaser and its Affiliates.

Notwithstanding the foregoing, the WELCO Pension Plan shall not recognize
employment with the Business after the Purchaser and its Affiliates have sold or
divested the Business, or a portion thereof (whether by asset or stock sale,
merger or spin-off (each a "Disposition")), with respect to the Business
                            -----------                                 
Employees who are transferred or terminated in connection with such a sale or
divestiture.

          (iii) The WELCO Pension Plan shall not provide for (A) any early
     retirement supplement that becomes payable with respect to a Business
     Employee retiring after the Closing Date that is the result of a "Pension
     Event" as defined in subsection (iv) below, (B) any benefits pursuant to
     Section 19 of the WELCO Pension Plan and the corresponding provision of the
     Purchaser Pension Plan, if any, in excess of the benefits that would
     otherwise be payable if those sections did not apply, with respect to a
     Business Employee who retires or terminates employment with the Purchaser
     and its Affiliates after the Closing Date, and (C) any other early
     retirement subsidy or supplement with respect to Business Employees that is
     not described in (ii) above.

          (iv)  Purchaser shall indemnify CBS for any actuarial losses (as
     defined below) with respect to the WELCO Pension Plan resulting from any
     Business Employee commencing the receipt of benefits prior to their Normal
     Retirement Date (as defined in the WELCO Pension Plan) and that is
     attributable to (A) a Disposition, (B) a closing of a plant or plants by
     Purchaser or a reduction in the number of Business Employees employed by
     the Purchaser and its Affiliates as a result of action requiring the filing
     of a notice under the Worker Adjustment and Retraining Notification Act, as
     in effect on the Closing Date (the "WARN Act"), other than termination at
                                         --------

     terminations

     announced by CBS prior to the Closing Date (or which would require the
     filing of a WARN Act notice if any actions taken within a 6-month period 
     occurred on the same date (a "WARN Event")), or (C) any action of the 
                                   ----------                      
     Purchaser or its Affiliates that provides a financial incentive to
     Business Employees to terminate or retire prior to their Normal Retirement
     Date including, but not limited to, an early retirement window program or a
     change in plan design which reduces prospective benefits for Business
     Employees who are eligible to retire under the WELCO Pension Plan (other
     than a change in plan design during the three (3) year period following the
     Closing Date, provided that Purchaser has Comparable Benefits (after one
     year from the Closing Date the value of the supplemental retirement
     benefits under the WELCO Pension Plan shall not be considered for
     comparability) after such change in plan design).  Purchaser shall notify
     CBS of the occurrence of any of the events described in (A) through (C)
     above (each of which is a "Pension Event") within 30 days after such event,
                                -------------                                   
     and shall cooperate with CBS in providing data to CBS to enable the
     determination of actuarial losses.  Actuarial losses shall be determined by
     the enrolled actuary for the WELCO Pension Plan (the "CBS Actuary") with
                                                           -----------       
     respect to each Pension Event and is measured by the difference (positive
     or negative) between the accumulated benefit obligation for all of the
     Business Employees affected by the Pension Event using (1) immediate
     commencement of benefits under actual forms of benefit payment elected and
     (2) projected commencement of benefits, both based on the assumptions
     described in Schedule 5.5(d), other than lump sums elected under (1) above,
     which shall be valued at the actual value distributed.  Notwithstanding any
     other provision in this Agreement to the contrary, this indemnity shall
     survive the Closing Date without limitation.

          (E) 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

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 


                                      73

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 (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 


                                      74
<PAGE>
 
     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(e)
     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.

          (F)   WELFARE BENEFITS.
                ---------------- 

          (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 copayments and
     deductibles incurred during the calendar year of the Closing.

          (ii)  Effective as of the Closing Date, Purchaser shall be responsible
     for all 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 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 domestic Business 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
     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
     shall be limited in each calendar year, commencing with the Closing Date,
     to the amounts set forth in Schedule 5.5(f)(iv) of the Disclosure Schedule
     (the "OPEB Schedule"), as described below.  The OPEB Schedule shall be
           -------------                                                   
     updated by CBS after the Closing Date to reflect Business 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 Purchaser FAS 106
     Plans 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 Business 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, their eligible
     spouses and dependents for all post-retirement welfare benefits (including
     retiree medical and retiree life) (other than amounts paid by CBS or a Sold
     Subsidiary 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 


                                      76
<PAGE>
 
     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 Business 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
     Business 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
     the Pensacola Plant), 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 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(f)(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 to the extent
     required by a final, non-appealable court order or as otherwise agreed to
     by the parties, but in any event the OPEB Schedule shall not be increased
     above the amount as in effect immediately prior to the change that
     triggered 


                                      77
<PAGE>
 
     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.

          (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 WELCO FAS 106 Plans and the Purchaser FAS 106 Plans as applicable
     to Business 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 allocable to such
     Business Employees and Former Employees.  The trust to be established by
     the 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 and with respect
to the Pensacola Plant in connection with the planned termination of Business
Employees whether before or after 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 or their Affiliates prior to the Closing Date
for purposes of determining the amount of such severance and other separation
benefits. 


                                      78
<PAGE>
 
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.  (i)  Effective as of the Closing Date,
                ----------------------                                         
Purchaser shall adopt and establish a plan for the benefit of Business Employees
that contains terms and conditions (including but not limited to eligibility
requirements) that are substantially similar to those of the Westinghouse
Executive Pension Plan in effect as of the Closing Date (the "WELCO Executive
                                                              ---------------
Plan") and which provides credit for prior service and compensation under the
- ----                                                                         
WELCO Executive Plan for purposes of eligibility and benefit accrual (the
"Purchaser Executive Plan"), provided, however, that the Purchaser Executive
 ------------------------
Plan will include provisions which are consistent with (ii) through (iv) below
and will have its benefits offset by the benefits provided under the WELCO
Executive Plan, the WELCO Pension Plan and the Purchaser Pension Plan.  The
Purchaser Executive Plan shall be administered so that the aggregate of the
benefits under the WELCO Executive Plan and the Purchaser Executive Plan are the
same with respect to Business Employees as if the Business Employees were
covered under the WELCO Executive Plan and continued employment with Sellers.

          (ii)  Purchaser shall continue the Purchaser Executive Plan without
adverse effect, including provisions therein relating to early retirement and
compensation increases, for a period not less than the Benefits Maintenance
Period.

          (iii) The WELCO Executive Plan shall retain liability, if any, for
benefits earned to the Closing Date with respect to Business Employees, to be
calculated pursuant to appropriate action to be taken by CBS with respect to the
WELCO Executive Plan to cause the WELCO Executive Plan to take into
consideration (i) credit for employment of Business Employees with the Purchaser
and its Affiliates solely for purposes of calculating eligibility for the
payment of benefits, (ii) that the Average Annual Compensation and Executive
Benefit 


                                      79
<PAGE>
 
Service (both as defined in the WELCO Executive Plan) will be determined
and frozen as of the Closing Date, and (iii) that the Purchaser and its
Affiliates will be considered a Designated Entity (as defined in the WELCO
Executive Plan) solely for purposes of determining eligibility for the payment
(including suspension of payment) of benefits.  Notwithstanding the foregoing,
the WELCO Executive Plan shall not recognize employment with the Business after
the Purchaser and its Affiliates have sold or divested the Business, or a
portion thereof as a result of a Disposition with respect to the Business
Employees who are transferred or terminated in connection with such a sale or
divesture.

          (iv) The Purchaser Executive Plan (or, if none, Purchaser) shall be
solely responsible for (and the WELCO Executive Plan shall not provide for) (x)
any benefit that becomes payable with respect to Business Employees retiring
after the Closing Date that is the result of a Pension Event (i.e. the benefit
would not be payable absent such an event) or (y) any other early retirement
subsidy or supplement that is not described in (iii) above.

          (v)  Purchaser shall indemnify CBS for any actuarial losses (based on
the same actuarial assumptions and methods used for purposes of determining
actuarial losses under Section 5.5(d)(iv)) with respect to the CBS Executive
Plan resulting from any Business Employee commencing the receipt of benefits
prior to their Normal Retirement Date (as defined in the WELCO Pension Plan) and
that is attributable to a Pension Event.  Purchaser shall cooperate with WELCO
in providing data to CBS to enable the determination of actuarial losses.
Notwithstanding any other provision in this Agreement to the contrary, this
indemnity shall survive the Closing Date without limitation.

          (I)  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.

          (J)  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.

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

          (L)  WORKERS COMPENSATION.  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 as are
provided under CBS's Workers Compensation Program for the Business Employees and
Inactive Employees covered by such program ("Purchaser's Workers Compensation
                                             --------------------------------
Program").  Purchaser's Workers Compensation Program shall be responsible for
- -------                                                                      
all claims for benefits which are payable from and after the Closing Date with
respect to employees and Former Employees of the Business and that are payable
under the terms and conditions of Purchaser's Workers Compensation Program or
the CBS's Workers Compensation Program.

          (M)  RETAINED LIABILITIES.  CBS shall retain liability and
               --------------------                                 
responsibility for all benefits payable under (x) the WELCO Pension Plan (but,
with respect to Business Employees, as limited under Section 5.5(d)), (y) the
WELCO Executive Pension Plan (but, with respect to Business Employees, as
limited under Section 5.5(h)), (z) the WELCO FAS 106 Plans with respect to
employees and former employees of the Business other than Business Employees
and, with respect to Business Employees, only to the extent provided in Section
5.5(f), (xx) the WELCO Savings Program (other than with respect to assets and
liabilities to be transferred to the Purchaser's 401(k) Plan under Section
5.5(e)), (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).

          (N)  ACTUARIAL DETERMINATIONS AND PAYMENTS.  (i)  The calculations of
               -------------------------------------                           
actuarial losses under subsections (d)(iv) and (h)(v) and 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
Pension Event or 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 Pension Event or a FAS 106 Event.

          (ii) No later than 60 days after the receipt by CBS of both the notice
from Purchaser that a Pension Event or 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 loss or actuarial
gain (each a "Determination"), respectively, 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 


                                      81
<PAGE>
 
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
or actuarial cost, 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 loss
under Sections 5.5(d)(iv) or 5.5(h)(v), Purchaser shall make any applicable
indemnification payments under such Sections.

          (vi)  All indemnification payments under (v) above shall be treated as
purchase price adjustments for tax purposes.

          (vii) 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.

          (O)   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.

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.

the case of Purchaser, establishing legal entities to serve as plan sponsor) to
establish Purchaser or Purchaser Affiliates as successor to CBS or its
Affiliates to all rights, assets, duties, liabilities and obligations under or

Business Employees and to have Purchaser or any Sold Subsidiary assume or retain
all obligations and liabilities relating to their employment (including, but not

foreign jurisdiction and who, as of the Closing Date, are not employed by CBS or
any of its affiliates (the Foreign Business Employees and such former foreign
employees, collectively, the "Foreign Plan Participants") on substantially
                              -------------------------

funding vehicles to hold assets or reserves of New Foreign Retirement Plans

Plan.

          (C)  Except as otherwise specifically provided in this Section 5.5(q),
effective as of the Closing Date, each Foreign Plan Participant who is an active
participant in any Foreign Retirement Plan shall cease to be an active
participant thereunder, and all Foreign Plan Participants shall become eligible

          (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 Energy Systems Business 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)(xiv)) 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(c).

          (b) After the Closing, Purchaser shall furnish or cause to be
furnished to CBS and its respective accountants, counsel and other
representatives access, during normal business hours, to such information
(including records pertinent to the Business), personnel and assistance,
including audit rights, relating to Purchaser's compliance with, and discharge
of its obligations under, the Settlement Agreements.

          (c) After the Closing, upon reasonable written notice, CBS will
deliver at Purchaser's expense all reasonably available records regarding the
conception, reduction to practice, evaluation, and efforts to patent or
otherwise protect Intellectual Property or 


                                      87
<PAGE>
 
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(c) 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 


                                      88
<PAGE>
 
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 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) Schedule 5.14 sets forth the allocation of the consideration
hereunder for each of the Foreign Sold Subsidiaries for Tax purposes.   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 U.S. Sold Subsidiary for all applicable Tax
purposes, including Code Section 1060.  To the extent permissible under
applicable Tax Laws, all Assumed Liabilities arising out of the Steam Generator
Settlement Agreements shall be treated as expenses of Purchaser, deductible by
it as such Liabilities are paid in taxable periods after the Closing Date; all
other Assumed Liabilities arising out of the Steam Generator Settlement
Agreements shall be included in the costs capitalizable by Purchaser at the
Closing.  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, 


                                      89
<PAGE>
 
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.

          (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 


                                      90
<PAGE>
 
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.

          (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) To the extent permitted by Law, Purchaser shall have the right to
cause each Foreign Sold Subsidiary to carry back any item of income, loss,
credit or deduction from any taxable period beginning after the Closing Date to
any taxable period including or ending prior to the Closing Date to the extent
Tax remains payable after all CBS Tax benefits have been taken into account.

          (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 U.S. Sold Subsidiary and
(B) CBS shall also file and shall cause each 


                                      91
<PAGE>
 
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 U.S. 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 (A) all Taxes covering
the Acquired Assets or the Sold Subsidiaries for all Straddle Periods and (B)
all Income Taxes of the Foreign Sold Subsidiaries for all Pre-Closing Tax
Periods, except as provided in Section 5.14(i).  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.

              (ii)  Purchaser shall prepare and file all Tax Returns for all
Foreign Sold Subsidiaries for all Post-Closing Tax Periods and all Tax Returns
other than Income Tax Returns for all Sold Subsidiaries for Pre-Closing Tax
Periods 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


                                      92
<PAGE>
 
               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 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 


                                      93
<PAGE>
 
     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
     -------------                                                     ---

     -------------                                       --------  -------     
     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.

          (m)  Purchaser acknowledges that CBS may, in its sole discretion,
elect under Treasury Regulation (S) 301.7701-3(c) to treat one or more Selling
Subsidiaries or Sold Subsidiaries that are foreign corporations as branches of
the applicable Sellers for United States federal income tax purposes, such
elections, if made, to be effective on or before the Closing Date and, where
necessary, take reasonable actions to enable such elections to be made.
Purchaser will not take or cause to be taken any Tax reporting position with
respect to such Selling Subsidiaries or Sold Subsidiaries that is inconsistent
with such elections.

          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," 


                                      94
<PAGE>
 
"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 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 in 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

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 


                                      96
<PAGE>
 
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 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.


                                      97
<PAGE>
 
          (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 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
                        ------------------

          SECTION 5.21. BUSINESS RELATIONSHIPS WITH SELLERS.  CBS and Purchaser
                        -----------------------------------                    
acknowledge that the Business has had relationships with other businesses within
Sellers, including performance obligations under Contracts, which have not been
documented by a formal written agreement.  In particular, the Business has been
involved with the GESCO Businesses, the Process Control 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. SCIENCE AND TECHNOLOGY CENTER.  CBS operates a Science
                        -----------------------------

CBS has entered into a sublease arrangement with Northrop Grumman with respect
to a portion of the STC premises and will enter into a sublease arrangement with
Siemens Power Generation Corporation with respect to the portion of the STC
premises utilized for the Power Generation Business.  The Acquired Assets shall

on the Closing Date and used or held for use primarily in the portion of the STC
which primarily provides research and development support to the Business or to
the performance of those programs ("STC Programs") (a) set forth in Schedule
                                    ------------

material respects, of programs sponsored or being performed by the Energy
Systems Business on behalf of itself or third parties as of the date hereof) or
(b) entered into or undertaken in the Ordinary Course of Business between the
date of this Agreement and the Closing Date which relate primarily to the
Business.  The provisions of Section 5.5 shall be applicable to all STC
Employees to the extent provided 


                                      99

primarily render services that provide research and development support to the
Business or on behalf of any STC Programs (and such other employees located at
STC as Seller and Purchaser may mutually agree) shall constitute the "STC
Employees."

          On the Closing Date, CBS shall sublease to Purchaser a portion of the
premises and the Fixtures and Equipment at the STC necessary to the effective

appropriate interest in the common areas at such premises pursuant to a mutually
acceptable sublease containing the terms and conditions set forth in Schedule
5.22, as well as customary terms and conditions and such other terms and
conditions as are reasonably acceptable to the parties.  Purchaser and CBS agree
that the terms of the sublease with respect to the premises shall not be
materially more restrictive to Purchaser than the terms of the master lease with
respect to the STC are to CBS.  CBS agrees to provide Purchaser with a copy of
the master lease with respect to the STC.  On the Closing Date, subject to
Section 2.2(c), Purchaser shall assume all Liabilities associated with the STC
Programs.

          SECTION 5.23. U.S.-CONTROLLED ENTITY.  For at least three (3) years

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

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)

each Sold Subsidiary waivers as of the Closing Date of any claim such director
may have against Purchaser or the Sold Subsidiaries.

          SECTION 5.27. THIRD PARTY AGREEMENTS.  CBS has provided Purchaser with
                        ----------------------                                  
a true and complete copy of the forms of (or term sheets relating 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 form
so provided, Purchaser shall acquire CBS' rights and assume CBS' 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. CBS shall

form of the business supply agreement to be entered into with the purchaser of
the Process Control Business to confirm that it is substantially on the terms

     to Sections 2.3(a)(vii) and 2.3(a)(xvi));

          (vi)  the matters set forth in the first paragraph of Schedule

          (A) CBS shall not have any Liability under clause (i) above unless the
              aggregate of all Losses relating thereto for which CBS would, but
              for this clause (A), be liable under clause (i) above exceeds
              $40,000,000, and then only to the extent of any such excess;

              above and determining the aggregate of all Losses pursuant to
              clause (A) of this proviso, CBS shall not have any Liability for
              any Loss in respect of such 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 and Annex

              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 $25,000,000, in which case, (w) for aggregate Losses of
              more than $25,000,000, but less than $50,000,000, CBS shall pay
              50% of such Losses, (x) for aggregate Losses of $50,000,000 or

          (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;

          (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 $16,000,000 (subject to reduction as provided in Schedule
              8.1(a)(vi)), and then (x) each of CBS and Purchaser shall be
              liable for fifty percent (50%) of the first $20,000,000 in
              aggregate Losses in excess of such amount and (y) CBS shall be
              liable for one hundred percent (100%) of any such Losses in excess

              8.1(a)(vi)); and

          (H) CBS shall not have any Liability in respect of any Losses under
              clause (vii) above except to the extent that the aggregate of all
              such Losses for which CBS would, but for this clause (H), be
              liable under such clause (vii) exceed $155,000,000.

          With respect to Losses for which CBS has Liability pursuant to
Sections 8.1(a)(v) or (vii) 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 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.


                                      110

          Notwithstanding any other limitation in this Section 8.1, with respect
to the Waltz Mill Service Center, CBS shall, at its sole cost and expense,
implement all remedial measures, including removal and decontamination
activities, as may be required by and are in accordance with approvals received
or to be received from the NRC (the "Plans") (x) in those areas of the Waltz
Mill Service Center identified in the Plans as "Retired Facilities" and (y)
which are associated with the termination of the TR-2 NRC License, which Plans
are incorporated herein by reference.  CBS shall have the responsibility and
sole and exclusive authority to negotiate with and respond to the NRC (and any
other Governmental Authority) with respect to any issues which may arise during
implementation of the Plans, including, but not limited to, dose assessment and
surveying issues.  CBS shall continue to be obligor with respect to
responsibility and liability for implementing the Plans and shall so advise the
NRC. Purchaser shall have the right, at its sole cost and expense, to review and
provide CBS with written comments in a reasonable time prior to transmission of
plans, reports and submissions to the NRC or any other Governmental Authority
and CBS shall review and in good faith consider any of Purchaser's comments on
such plans, reports and submissions.  Any dispute between CBS and Purchaser with
respect to such plans, reports and submissions shall be addressed in the manner
set forth in Section 8.8 of this Agreement (Arbitration of Certain Environmental
Liabilities).  Notwithstanding any leasehold interest Purchaser may have in the
Waltz Mill Services Center Facilities, Purchaser shall afford CBS, its agents,
employees, contractors, subcontractors and other representatives reasonable
access to the Waltz Mill Service Center from and after the Closing, until such
time as the Plans have been completed and NRC has approved completion of the
Plans.  Such access shall also include access to electrical, water, and other
utilities as may be required by CBS to implement the Plans.  Such access shall
include, but not be limited to, the laboratory, boiler room, health physics
area, engineering and electrical room.

          Notwithstanding the foregoing, from and after the time, if any, as
clause (E)(z) or (H) of the third 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 


                                      111
<PAGE>
 
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 or Annex S, 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 the Agreement (other than those contained in
Section 2 of Annex S) 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); provided that nothing in
                                                      --------                
this Section shall eliminate, diminish or otherwise affect Purchaser's
obligations under Sections 3 and 4 of Annex S.


          (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 and except as provided in Annex S
with respect to Steam Generator Liabilities) 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 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 and Annex S, 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:


                                      112
<PAGE>
 
          (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);

          (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, including all
     Liabilities which arise from, relate to or are otherwise in respect of
     Purchaser's D&D (as defined in Section 8.1(a)(vii)); or

          (x)    the termination, cessation, or alteration of Purchaser's
     activities at the Waltz Mill Service Center site, but only to the extent
     that such termination, cessation, or alteration gives rise to incremental
     Decontamination and Decommission Liabilities associated with a change in
     site use classification by a Governmental Authority from industrial to non-

     forth in Section 8.8.

          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.

          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), (vi) or (vii) of Section 8.1(a) or
     Sections 3 and 4 of Annex S.

          (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 


                                      114
<PAGE>
 
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 Energy Systems Business 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.

          (d) Notwithstanding anything to the contrary in this Agreement and the
GESCO 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 Section 3(b) of Annex S, shall terminate on the
fourth anniversary of the Closing Date; (e) pursuant to clause (a)(vii) of
Section 8.1 shall terminate as to any equipment or facility on the earliest of
(i) the tenth anniversary of the Closing Date, (ii) the expiration or voluntary
or involuntary termination of an NRC Permit or Permit issued by a foreign
Governmental Authority after the Closing Date giving rise to Decontamination and
Decommissioning Liabilities, and (iii) the discontinuance or closedown of a
facility after the Closing Date giving rise to Decontamination and
Decommissioning Liabilities; and (f) pursuant to the other clauses of Sections
8.1 and 8.2 and Annex S shall not terminate.

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


                                      115
<PAGE>
 
          (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
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 


                                      116
<PAGE>
 
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 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,
whether a cost or Loss is a Decontamination and Decommissioning Liability or the
matters concerning the Waltz Mill Service Center described in Sections 8.1(a)
and 8.2(x) shall be settled by arbitration in accordance with the Commercial
Rules of the American Arbitration Association. 


                                      117
<PAGE>
 
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
                                                                            
"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.


                                      118
<PAGE>
 
          (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-day administration of any Shared Claim shall be provided for in such
     agreements.

          SECTION 8.10. STEAM GENERATOR MATTERS.  Annex S is incorporated herein
                        -----------------------                          
as if fully set forth herein.

          SECTION 8.11. 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

          (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

part of this Agreement as if fully set forth in this Agreement.  When a
reference is made in this Agreement to a Section, Exhibit, Annex or Schedule,
such reference shall be to a Section of, or an Exhibit, Annex or Schedule 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

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

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

          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

(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

          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

spokesperson of each such party.


                                      123
<PAGE>
 
          (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 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 


                                      124
<PAGE>
 
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.

price for the Acquired Assets (the "Purchase Price") shall consist of
                                    --------------                   

          (a) the payment by Purchaser of $237,500,000 (the "Cash Portion"),

           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.  The Statement of Working
Capital shall become final and binding upon the parties on the 60/th/ 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 

                                      28
<PAGE>
 
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 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 

                                      29
<PAGE>
 
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 

                                      30
<PAGE>
 
recognized as a fixed asset on the books of the Business as of the Balance Sheet
date and (y) but for such loss 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.

<PAGE>
 
          (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 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.

           SECTION 4.1.  REPRESENTATIONS AND WARRANTIES OF CBS.  CBS hereby
                         -------------------------------------             
represents and warrants to Purchaser as follows:

          (A) ORGANIZATION, STANDING AND POWER.  CBS is a corporation duly

liability company power and authority to own its assets and to carry on its
business as now being conducted and is duly qualified to do business in each
jurisdiction in which the nature of its business or properties requires such
qualification, except for failures to qualify that, individually or in the
aggregate, would not have a Material Adverse Effect.

          (B) AUTHORITY.  CBS has the requisite corporate power and authority to
              ---------

Closing pursuant hereto (the "Seller Ancillary Documents") and to consummate the
                              --------------------------
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Seller Ancillary Documents to which CBS is a party and the
consummation of the transactions contemplated hereby and thereby have been duly
authorized by all necessary corporate action on the part of CBS, and, in the
case of the Seller Ancillary Documents, will be authorized by all necessary
corporate action on the part of the Selling Subsidiaries prior to the Closing,

Agreement has been duly executed and delivered by CBS and constitutes, and each
Seller Ancillary Document to be entered into by any of Sellers will be duly
executed and delivered at the Closing and when so executed and delivered will
constitute, a legal, valid and binding obligation of each of the Sellers party
thereto enforceable against it in accordance with its terms, subject to the
Bankruptcy Exception (as defined below). The execution and delivery of this
Agreement by CBS do not, and the execution and delivery by Sellers of the Seller
Ancillary Documents, the consummation by Sellers of the transactions
contemplated hereby and thereby and the compliance by Sellers with the terms
hereof and thereof will not, conflict with, or result in any violation of or
default (with or without notice or lapse of time, or both) under, or give rise
to a right of termination, cancellation or acceleration of any obligation
(except, to the extent provided in any such program or plan, any acceleration of
vesting under the Westinghouse Savings Program or under any Pension Plan or 
long-term incentive plan) or to the loss of a material benefit under, or 
result in the creation of any Lien upon any of the Acquired Assets under, any 
provision of (i) the Business Corporation Law of the Commonwealth of 
Pennsylvania, (ii) the certificate of incorporation or by-laws (or comparable 
organizational documents) of any of Sellers or the Sold Subsidiaries, (iii) 
except as disclosed on Schedule 4.1(b)(i), any Intellectual Property, 
Technology, contract, lease, indenture or other agreement of any Seller or 
Sold Subsidiary or (iv) subject to the filings and other matters referred to 
in the following sentence, any Law applicable to Sellers, the Sold 
Subsidiaries, the Acquired Assets or the Subsidiary Assets, other than, in the
case of clauses (iii) and (iv) above, any such conflicts, violations, defaults,
rights or Liens that, individually or in the aggregate, would not (A) 
reasonably be expected to have a Material Adverse Effect or (B) materially 
impair the ability of CBS 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 to be

          (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 

                                      35
<PAGE>
 
     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 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 

                                      36
<PAGE>
 
     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 contract or project. This Section 4.1(d)
     does not relate to litigation matters (to which Section 4.1(e) is
     applicable), labor and employment matters (to which Section 4.1(q) is
     applicable), employee benefits matters (to which Section 4.1(m) is
     applicable), Environmental Laws (to which Sections 4.1(j)(B) and 4.1(n) are
     applicable) or Tax matters (to which Section 4.1(o) is applicable).

          (ii)   Except as set forth in Schedule 4.1(d)(ii), with respect to the
     Acquired 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 is a
party and which, if still pending on the Closing Date, would be an Assumed
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.

This Section 4.1(f) does not relate to Intellectual Property or Technology (to
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  

                                    38


<PAGE>
 
     (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 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 

                                      39
<PAGE>
 
     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 

                                      40
<PAGE>
 
     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 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 

                                      41
<PAGE>
 
     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
                 ---------

Assets, the Subsidiary Assets and the Business.   Such policies and binders are

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.

          (x)      a Contract providing for the formation of any joint venture,
     long-term alliance, partnership or material teaming agreement or
     arrangement;

          (xi)     a Contract for the sale of any of the assets or properties of

     obligations of any Seller or Sold Subsidiary in an amount in excess of
     $1,000,000; and

          (xv)     a material license or development agreement.

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
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).

                                      44
<PAGE>
 
          (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. (S) 970.5204-31 (1997), (B) 48 C.F.R. (S) 970.5204-61
(1997), or (C) 48 C.F.R. (S) 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. (S) 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) and except for the Excluded Assets (other than those described in clause
(viii) of the definition 


                                      45
<PAGE>
 
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 

                                      46
<PAGE>
 
     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 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.

                                      47
<PAGE>
 
          (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.

          (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 

                                      48
<PAGE>
 
     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, sever  ance, 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.

          (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.

          (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,

          (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

     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

     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

     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

stock of each Sold Subsidiary are owned, directly or indirectly, beneficially

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

is no pending, and since December 31, 1997 through the date hereof there has not

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

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.

           (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

     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

          (a)  CBS shall afford to Purchaser and its accountants, counsel and
other representatives reasonable access at reasonable times during the period
prior to the Closing to all the properties (including the GESCO government-owned
sites), books, Contracts, commitments, Tax Returns, pending bids and proposals
for contracts (excluding contracts for which CBS believes Purchaser or any of
its Affiliates is a competing bidder), and records of the Business (other than
to the extent such information relates to the Excluded Assets or Excluded
Liabilities), and during such period shall furnish promptly to Purchaser any

                                      61
<PAGE>
 
information concerning the Business (other than to the extent such information
relates to the Excluded Assets or Excluded Liabilities) as Purchaser may
reasonably request and shall use reasonable commercial efforts on a timely basis
to obtain any counterparty or third-party consents necessary to permit Purchaser
access to such information; and shall cause its and the other Sellers' officers,
employees, consultants, agents, accountants and attorneys to cooperate
reasonably with Purchaser's representatives in connection with such review and
examination; provided, however, that CBS is under no obligation to disclose to
             --------  -------                                                
Purchaser (i) any information the disclosure of which is restricted by
applicable Law except in strict compliance with the applicable Law, (ii) any
information as to which the attorney-client privilege, the attorney work-product
doctrine or the self-evaluative privilege may be available, except to the extent
covered by the Joint Defense Agreement referred to in Section 5.28 or, if not so
covered, until a mutually satisfactory joint defense agreement has been executed
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) 

                                      62
<PAGE>
 
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 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 

                                      63
<PAGE>
 
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 Govern  mental 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."  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 

                                      64
<PAGE>
 
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, (P) 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, (P)
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.

                                      65
<PAGE>
 
          (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

                                      66
<PAGE>
 
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 

                                      67
<PAGE>
 
     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 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

     for Business Employees on the date of this Agreement ("Comparable

     ------------------                                                 
     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

<PAGE>
 
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.

          (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 

                                      69

     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 (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 

                                      70
<PAGE>
 
     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 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 

                                      71
<PAGE>
 
     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 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-

                                      72
<PAGE>
 
     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 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 

                                      73
<PAGE>
 
     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 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 

                                      74
<PAGE>
 
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 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.

                                      75
<PAGE>
 
          (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 Section 5.5(n).

                                      76
<PAGE>
 
          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 


                                      77
<PAGE>
 
and the amount the True-Up Payment would have been if the final percentage were
known at 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 

                                      78
<PAGE>
 
     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.

          (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

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

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
                        --------

                                                           -----------------
Agreement"), wherein, to the extent CBS and Purchaser have rights on the Closing
- ---------

     appropriate access to the corresponding technology reasonably required for
     the licensed purpose.  Such right of access to technology shall be

     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.

          SECTION 5.1.  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

                                      81
<PAGE>
 
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 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.

                        ------------------                                     
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 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.

          (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.

          (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 

                                      85

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.

          (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:


                                      86
<PAGE>
 
          (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 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
                                                       -------------

     -------------                                       --------  -------     
     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

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 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 

                                      88

          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

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) 

                                      89
<PAGE>
 
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 

                                      90
<PAGE>
 
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 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.

                                      91
<PAGE>
 
          (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 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:

acceptable arrangements relating to the use of (i) facilities and equipment by

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 (3) years
                        ----------------------                               
after the Closing, Purchaser (i) shall (for so long as it owns the Business or
any 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.
Purchaser shall during such period take all actions necessary, as required, to
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

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

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

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)

to such workers compensation data, all at its expense, as may be necessary to
conduct an actuarial reserve analysis.

7.1 and (v) Article 9.  Nothing in this Section 7.1 shall be deemed to release

          SECTION 7.2.  AMENDMENTS AND WAIVERS.  This Agreement may not be
                        ----------------------

          (iii) any Liability of any Seller which is not an Assumed Liability

          (v)   (A) any breach of any representation or warranty contained in

provided, however, that
- --------  -------      

          (A) CBS shall not have any Liability under clause (i) above unless the
              aggregate of all Losses relating thereto for which CBS would, but
              for this clause (A), be liable under clause (i) above exceeds
              $8,000,000, and then only to the extent of any such excess;

          (B) CBS shall not have any obligation to pay, in respect of Losses
              indemnifiable pursuant to clause (i) above, an amount in excess of
              $200,000,000 in the aggregate;

          (C) for purposes of calculating Losses under clauses (i) and (ii)
              above and determining the aggregate of all Losses pursuant to
              clause (A) of this proviso, CBS shall not have any Liability for
              any Loss in respect of such 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;

                                      100
<PAGE>
 
          (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 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 

                                      101
<PAGE>
 
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 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 


                                      102

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.

                        --------------------------------------------------
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.

          (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 


                                      105
<PAGE>
 
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
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 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 


                                      107
<PAGE>
 
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
                                                                            
"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 

                                      108
<PAGE>
 
     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-day administration of any Shared Claim shall be provided for in such
     agreements.

          SECTION 8.1.  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.

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
                    --------    --------      ---------

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
         ---------

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 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 


                                      113
<PAGE>
 
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

     4.2  Management.
          ---------- 

          (a) Management by Managers.  GESCO I will be managed by a board of
              ----------------------                                        
              directors or managers (the "Board") selected by the members, and
              by officers appointed by the Board.

          (b) Board.  With effect from the GESCO Closing Date, GESCO I will have
              -----

              selected jointly by MK and BNFL-USA (who initially will be Charles

              directors and who satisfies the requirements to be the chairman of
              a US Government Security Committee (the "Sixth Director"). Each of
              the directors shall be a US citizen. Each director will serve for
              a one-year term, and will be eligible for re-appointment in
              accordance with this paragraph (b), provided that MK and BNFL-USA
              shall have the right to replace their respective appointees at any
              time and MK and BNFL-USA, acting jointly, shall have the power to
              replace the Chairman and to require the remaining directors to
              replace the Sixth Director.

          (c) Officers.  The Board will appoint a President and other officers

              as desired from time to time. The officers will have the
              authority, responsibilities and duties as are customary for
              officers holding similar positions with respect to businesses
              conducted in corporate form and such additional authority,
              responsibilities and duties as the Board may delegate from time to
              time.

     4.3  Bidding.  GESCO I will be the preferred vehicle for rebidding its

          existing contracts. With respect to other contracts that fall within
          the scope of the GESCO I Operations, it is the objective of the
          parties to maintain and grow the value of GESCO I, consistent with the
          interests of MK and BNFL-USA, and to maximize the competitive
          positioning of GESCO I bids. However, if MK and BNFL-USA do not agree
          that it would be advantageous to bid a specific contract through GESCO
          I, MK and BNFL-USA are both free to bid that contract directly or in
          concert with a different partner or partners and GESCO I will not bid.

     4.4  Electro-Mechanical Division.  The Electro-Mechanical Division (the
          ---------------------------                                       
          "EMD") (which is currently included within GESCO I) may or may not be
          permitted to be held in GESCO I. If the EMD is not permitted to be
          held in GESCO I, then a separate entity ("GESCO III") may be organized
          to hold the EMD. The 

                                       4
<PAGE>
 
          ownership, management, operation, financing and other attributes of
          the EMD shall be the same in all material respects as for GESCO I. If
          ownership of the EMD in GESCO III is not acceptable to the US
          government, the parties will agree on a mutually agreeable ownership
          structure acceptable to the US government; provided that in any event
          MK and BNFL-USA shall provide an equal portion of the purchase price
          for, and shall share equally in the economic risks and rewards of, the
          EMD.

5.   ESBU.
     ---- 

     5.1  Members.  Wesco shall be the sole member of ESBU.
          -------                                          

     5.2  Management.
          ---------- 

          (a) Management by Managers.  Subject to the provisions of paragraphs
              ----------------------

              conducted in corporate form and such additional authority,
              responsibilities and duties as the Board may delegate from time to
              time.

          (d) Management Agreement.  With effect from the ESBU Closing Date,
              --------------------                                          
              ESBU will enter into a management agreement with BNFL-USA, or one

                                                            ---------

6.   Savannah River M&O Contract.
     --------------------------- 

     MK and BNFL-USA will hold the Savannah River M&O Contract (defined in
     Section 7.2(a)(iv)) in an entity acceptable to the US government, which
     will have ownership and control arrangements acceptable to the US
     government (which the parties currently believe will require the Savannah
     River M&O Contract to be performed by an organization wholly owned by MK).
     The ownership and control of such entity will also be mutually acceptable
     to MK and BNFL-USA; provided that in any event MK and BNFL-USA shall
     provide an equal amount of the purchase price for, and shall share equally
     in the economic risks and rewards of, the Savannah River M&O Contract.
     Appropriate protections will be provided to ensure that funds are not
     distributed to MK via contract or any other mechanism that would frustrate
     or avoid BNFL-USA's participation in the economic rewards of the Savannah
     River M&O Contract.

11.  MK's Financial Interest in ESBU.
     -------------------------------

          ------------------------------------                              
          Wesco are divided into two series (the Series A Interests and the
          Series B Interests) each of which will be owned by MK and BNFL-USA in
          the same 60:40 proportion. The 

                                       11
<PAGE>
 
          Series A Interests will represent all assets, liabilities and rights
          of Wesco that relate to or are derived from its ownership interest in
          GESCO I and, if formed, GESCO III. The Series B Interests will
          represent all assets, liabilities and rights of Wesco that relate to
          or are derived from its ownership interest in ESBU.

     11.2 Put/Call.  At any time after the third anniversary of the ESBU Closing
          --------                                                              
          Date, MK may require BNFL-USA to purchase MK's Series B Interest, and
          BNFL-USA may require MK to sell its Series B Interest. The sale price
          of MK's Series B interest will be the amount necessary to provide MK
          with a pre-tax 11 1/2% internal rate of return on its financial
          investment in its Series B Interest (taking into account all cash
          distributions and contributions).

12.  BNFL-USA's Contract with GESCO II.
     --------------------------------- 

     12.1 Nature of Right.  MK will own 100% of the outstanding shares of GESCO
          ---------------                                                      
          II. BNFL-USA will have a contractual right (the "BNFL Right") to
          receive payments from GESCO II in an amount such that taking the
          payments to BNFL-USA together with distributions from GESCO II to MK,
          BNFL-USA will receive 8% of such amounts. Such payments will continue
          until terminated as provided in Section 12.2. As reflected in Section
          3.2 above, BNFL-USA will have no right to influence or control the
          management or operations of GESCO II in any manner.

     12.2 Termination of Right.  The BNFL Right may be terminated in either of
          --------------------                                                
          the two following ways:

          (a) At any time after the third anniversary of the GESCO Closing Date
              BNFL-USA may require GESCO II to make a payment (the "Termination
              Payment") to BNFL-USA or GESCO II may elect to make a Termination
              Payment to BNFL-USA in accordance with the following.

              (i)  The Termination Payment will be an amount necessary to
                   provide BNFL-USA with a pre-tax 11 1/2% internal rate of
                   return on its Deemed Payment, after taking into account all
                   payments received by BNFL-USA with respect to the BNFL Right.

              (ii) BNFL-USA's "Deemed Payment" shall be an amount equal to 8% of
                   the portion of the purchase price paid on the GESCO Closing
                   Date under the GESCO Purchase Agreement that MK and BNFL-USA
                   agree is to be allocated to the GESCO II Business.

          (b) If at any time before either BNFL-USA or MK exercise its rights
              under Section 12.2(a), MK sells the GESCO II Business, MK will
              pay, or will cause GESCO II to pay, to BNFL-USA an amount (the
              "Sale Payment") such that BNFL-USA will receive 8% of the value of
              GESCO II established by such sale.

                                       12
<PAGE>
 
          The BNFL Right will terminate upon the  payment of the Termination
          Payment or the  Sale Payment.

     12.3 Miscellaneous.
          ------------- 

          (a) MK will guarantee payment GESCO II of its obligations under the
              BNFL Right.

          (b) The BNFL Right will include appropriate protections to ensure that
              funds are not distributed from GESCO II to MK via any contract or
              other mechanism in a manner that would frustrate or avoid BNFL-
              USA's rights to receive payments with respect to the BNFL Right.

          (c) The BNFL Right will be structured so as to permit MK to engage in
              ordinary cash management activities without being required to make
              payments to BNFL-USA.

13.  Protection of National Security and US Technology.
     ------------------------------------------------- 

     13.1 The parties will take all necessary actions to comply with applicable
          laws concerning the protection of US national security. Among other
          things, these actions will include, where necessary, electing as
          directors or appointing as managers persons with appropriate security
          clearances and forming government security committees.

     13.2 The parties will take all necessary actions to comply with applicable
          laws concerning the protection of US technology, including procedures
          to ensure that the licensing and sale of AP600 technology will be
          subject to appropriate review and control by US citizens.

14.  Indemnification.
     --------------- 

     14.1 Background.  The parties acknowledge and agree that

              Business, the GESCO II Business and, if necessary, the GESCO III
              Business by allocating them to the Companies as outlined in
              Section 7.

          (b) It is their intention that MK's exposure to liabilities arising
              from the ESBU Operations or the GESCO I Operations, and BNFL-USA's
              exposure to liabilities arising from the GESCO I Operations or the
              GESCO II Operations be limited as set forth herein.

          (c) In order to preserve the allocation of liabilities reflected by
              such actions, the parties agree that each of the parties and the
              Companies and their respective affiliates will be entitled to
              indemnification as set forth below.

     14.3 Indemnification.  With respect to any liability or claim that arises
          ---------------                                                     
          from the business or operations of any Second Tier Entity (or any
          predecessor):

          (a) GESCO II.  In the case of any liability of any kind or nature
              --------                                                     
              whatsoever (including liabilities existing on the GESCO Closing
              Date) that arises from the business or operations of GESCO II,
              GESCO II will indemnify and defend British Nuclear Fuels plc
              ("BNFL"), BNFL-USA, their affiliates, Wesco and any other Second
              Tier Entities and their affiliates and hold them harmless against
              any loss or expense arising from such liability or claim
              (including reasonable attorneys' fees but excluding consequential
              damages) ("Losses"). If the assets of GESCO II are insufficient to
              perform the required indemnification and defense, MK will

              affiliates, and Wesco and any other Second Tier Entities and their
              affiliates.

              ----

              other Second Tier Entities and their affiliates and hold them
              harmless against any Losses. If the assets of ESBU are
              insufficient to perform the required indemnification and defense,
              BNFL-USA will indemnify, defend and hold harmless MK-Delaware, MK,
              and their affiliates, and Wesco and any other Second Tier Entities
              and their affiliates.

          (c) GESCO I and GESCO III.   In the case of any liability of any kind
              ---------------------                                            
              or nature whatsoever (including liabilities existing on the GESCO
              Closing Date) arising from the business or operations of GESCO I
              or, if created, GESCO III, GESCO I or GESCO III, as the case may

              Second Tier Entities and its affiliates and hold them harmless
              against any Losses; provided that there shall be excluded from

              value of any equity interest in GESCO I or GESCO III held by MK,
              BNFL-USA or their affiliates. If the assets of GESCO I or GESCO
              III, as the case may be, are insufficient to perform the required
              indemnification and defense, BNFL-USA and MK will make appropriate
              payments to each other and their respective affiliates such that
              MK and its

     14.4  Limitations.  The provisions of this Section 14 shall be perpetual.
           -----------                                                        

     14.5 Notice and Cooperation.  Any party that has, or believes that it may

          affiliates in the investigation and defense of any liability or claim
          that may be the subject of this Section 14. Any disputes will be
          resolved as provided in Section 16.

15.  Technology Sharing Arrangements.
     ------------------------------- 

     15.1 The parties acknowledge that

          (a) The parties and their affiliates will enter into one or more
              technology sharing arrangements with CBS and certain of its
              affiliates, and certain third parties, in connection with the
              transactions contemplated by the Asset Purchase Agreements (the
              "CBS Technology Sharing Agreements"),

          (b) In order for ESBU, GESCO, GESCO II and GESCO III to obtain the
              benefit of the technology that is to be transferred, licensed or
              shared under the CBS Technology Sharing Agreements, it will be
              necessary for them to enter into appropriate arrangements for the
              further sharing or licensing of such technology through sublicense
              arrangements which will require the prior approval of CBS (which
              may not be unreasonably withheld).

          (c) The parties and their affiliates will enter into appropriate
              cross-licensing agreements with respect to intellectual property
              created by GESCO I, GESCO II, GESCO III and ESBU (and any of their
              subsidiaries) provided that (i) the cost of such licenses will be
              the cost of producing the intellectual property, and (ii) any
              GESCO II cross-licenses will be, and other cross-licenses may be,
              subject to appropriate limitations to protect US national
              security.

     15.2 MK and BNFL-USA will, and will cause their affiliates, including the

          representatives of their respective companies.

     16.2 If the dispute cannot be resolved by the CEO's, it will next be
          referred to an independent mediator agreed to by the parties.

     16.3 If the dispute remains unresolved after mediation, it will then be
          subject to binding arbitration under the rules of the International
          Chamber of Commerce at a mutually agreeable venue. If MK and BNFL-USA
          are unable to agree on a venue, the arbitration will take place at a
          neutral site other than the United States or the United Kingdom.

17.  Termination.  This Agreement will terminate automatically upon the

18.  Confidential Information.
     ------------------------ 

     18.1 The parties acknowledge that in order to carry out the purposes of
          this Agreement it will be necessary for them to disclose to the other

          of the disclosing party or its affiliates.

     18.2 Each party will take reasonable actions to identify to the other party
          any information that is confidential or proprietary, which will
          include marking or identifying such information (in whatever form it
          may be embodied) as "Confidential". All such information is referred
          to as "Confidential Information".

     18.3 Each party will treat the other party's Confidential Information as
          confidential, will not disclose it to any other person (other than
          those of its and its affiliates' officers, directors and
          representatives who need to know such information for the purpose of
          carrying out the transactions contemplated by the Agreement) or use it
          for any purpose other than carrying out the transactions contemplated
          by this Agreement.

     18.4 The restrictions imposed under this Section 18 shall remain in effect

          (a) with respect to any Confidential Information that constitutes a
              "trade secret" (as defined under the laws of the State of New

     THIS AMENDED AND RESTATED CONSORTIUM AGREEMENT (this  "Agreement"), dated
as of January __ 1999, by and between the following parties:

     *MORRISON KNUDSEN CORPORATION, an Ohio corporation ("MK"), and

     *BNFL USA GROUP INC., a Delaware corporation ("BNFL-USA").


WITNESSETH

     WHEREAS:

     1.   MK and BNFL-USA entered into a Consortium Agreement, dated as of June
          24, 1998 (the "ORIGINAL AGREEMENT"), pursuant to which they formed a
          consortium for the purpose of acquiring the Energy Systems business
          (the "ESBU BUSINESS") and the Government Operations business (the
          "GESCO BUSINESS") of CBS Corporation ("CBS").

     2.   The Original Agreement set forth the agreement of MK and BNFL-USA
          concerning the basis on which the ESBU and GESCO Businesses would be
          owned, and the basis on which ownership, control and risk would be
          shared after the acquisition.

     3.   On June 24, 1998 MK and BNFL-USA organized WGNH Acquisition, LLC, a
          Delaware limited liability company ("WGNH"), for the purpose of
          entering into asset purchase agreements with CBS for the acquisition
          of the ESBU and GESCO Businesses and acting as a holding company for
          MK and BNFL-USA's interests in the ESBU and GESCO Businesses.  WGNH is
          the entity referred to as "Wesco" in the Original Agreement and the
          ownership, governance and management of WGNH are currently set forth
          in the Original Agreement.

                                                                 CONFIDENTIAL 

     4.   WGNH entered into (i) an Asset Purchase Agreement, dated as of June
          25, 1998 (as it may be amended from time to time, the "ESBU PURCHASE
          AGREEMENT"), with CBS covering the acquisition by WGNH of the ESBU
          Business, and (ii) an Asset Purchase Agreement, dated as of June 25,
          1998 (as it may be amended from time to time, the ("GESCO PURCHASE
          AGREEMENT"), with CBS covering the acquisition by WGNH of the GESCO
          Business.  The ESBU Purchase Agreement and the GESCO Purchase
          Agreement are sometimes referred to individually as an "ASSET PURCHASE
          AGREEMENT" or collectively as the "ASSET PURCHASE AGREEMENTS".

     5.   Since the date of the Original Agreement (i) certain changes have
          occurred with respect to the scope of the GESCO Business, and (ii) MK
          and BNFL-USA have had further discussions with each other and with
          representatives of the United States government  and CBS concerning
          certain issues relating to the ownership and control of certain
          aspects of the ESBU and GESCO Businesses.  As a result of these
          changes and discussions WGNH will no longer act as a holding company
          for MK's and BNFL-USA's interests in the ESBU and GESCO Businesses and
          either by novation or assignment will transfer its rights and
          obligations under the Asset Purchase Agreements to other entities
          organized by the parties.

     6.   MK and BNFL-USA wish to amend and restate the Original Agreement in
          its entirety as set forth in this Agreement so as to set forth their
          revised agreement concerning the basis on which the ESBU and GESCO
          Businesses will be owned, and the basis on which ownership, control
          and risk will be shared after the acquisition.

     7.   MK and BNFL-USA intend to take certain actions and enter into certain
          other agreements as contemplated by this Agreement.

     8.   BNFL-USA has organized a new wholly-owned subsidiary, BNFL Nuclear
          Services, Inc., a Delaware corporation ("BNSI"), for the purpose of
          holding BNFL-USA's interests in the GESCO and ESBU Businesses.

     9.   Morrison Knudsen Corporation, a Delaware corporation ("MK-Delaware")
          which is the parent company of MK, and British Nuclear Fuels plc, a
          public limited company organized under the laws of England ("BNFL")
          which is the parent company of BNFL-USA, entered into guarantees of
          the obligations of MK and BNFL-USA, respectively, under the Original
          Agreement (the "ORIGINAL GUARANTEES") and wish to replace the Original
          Guarantees with guarantees of the obligations of MK and BNFL-USA and
          BNSI, respectively, under this Agreement in the form attached
          following the signature pages to this Agreement.

     and agreements contained in this Agreement, the Original Agreement,

          fact that WELCO may possess personnel and technology resources which
          could benefit the implementation of existing and future WGS and WGES
          contracts, such cooperation will include WELCO's commercially
          reasonable efforts, in accordance with this Section 9 and with Section
                                                      ---------          -------
          10,  to make available such personnel and technology resources to
          --                                                               
          support WGS and WGES and their subsidiaries and divisions in the
          conduct of government business.  It is the intention of the parties to
          share lessons learned in operational know-how and technology
          applications through personnel transfers, case studies and status
          seminars in a manner that is consistent with the provisions of this
          Agreement.

     9.3  Certain Defense and Other Programs.   WGS, WGES and WELCO will
          ----------------------------------                            
          cooperate, subject to Governmental Requirements and pursuant to
          appropriate commercial arrangements to be negotiated in good faith, to
          support WELCO's participation in  Defense Program initiatives.

     9.4  Bidding.  Subject  to Governmental Requirements and other applicable
          -------                                                             
          law, WGS and WGES in the areas of business respectively assigned to
          them will be the preferred vehicle for bidding primary Management and
          Operations and Management and Integration contracts on DOE and DOD
          sites with the objective of growing the value and enhancing the
          competitiveness of WGS and WGES consistent with the interests of MK
          and BNFL-USA.  If MK and BNFL-USA agree that it would not be
          advantageous or consistent with their interests to bid a specific
          contract through WGS or WGES, as the case may be, they shall agree on
          the appropriate vehicle for jointly bidding such contract, subject to
          the following sentence.  If either MK or

          BNFL-USA believes that jointly bidding a specific contract (using any
          vehicle) would potentially have a material adverse impact on MK or
          BNFL-USA, then and only after MK and BNFL have attempted to resolve
          and have been unable to resolve any differences of opinion regarding
          the potential for material adverse impact, will MK or BNFL-USA (or
          their respective affiliates) be free to bid that contract directly or
          in concert with a different partner or partners, and WGS and WGES will
          not bid. Any disputes with respect to this Section 9.4 will be
          resolved pursuant to the procedures set forth in Section 12.

     9.5  MK Preferred Provider of EPCM and Facilities O&M Services.  Subject to
          ---------------------------------------------------------             
          Governmental Requirements and other applicable law, MK shall be the
          preferred supplier to WELCO (and to WELCO's customers where WELCO has
          the right to choose its customer=s suppliers) for planning,
          constructing, demonstrating, operating, maintaining, repairing, and
          upgrading nuclear power generation facilities and facilities of any
          kind in connection with WELCO's commercial nuclear and/or steam
          operations to the extent WELCO intends to contract with any party for
          such services (hereinafter referred to as "EPCM/O&M Services").
          Accordingly, WELCO will negotiate with MK in good faith (and will
          recommend MK and seek to encourage its customers to so negotiate with
          MK) to provide EPCM/O&M Services that MK is qualified to perform.  If
          WELCO desires to competitively bid EPCM/O&M Services and MK is
          qualified to perform such EPCM/O&M Services, MK shall have the right
          to perform such EPCM/O&M Services at the same price and subject to the
          same terms and conditions as the terms and conditions of a bona fide
          bid by a competitive bidder that WELCO would otherwise contract with
          to perform such services.  If WELCO does not believe MK is qualified
          to perform such EPCM/O&M Services then the matter will be resolved
          pursuant to the procedures set forth in Section 12.  The foregoing
          provisions of this Section 9.5 do not apply to the extent such
          EPCM/O&M Services are subject to statutory and/or regulatory
          requirements mandating competitive bidding and prohibiting the
          exercise by MK of such right.  In addition, the arrangements between
          MK and BNFL-USA provided for in this Section 9.5 are subject to
          arrangements, existing on the Closing Date, of WELCO or its
          predecessors or affiliates.

     9.6  General and Administrative Services.  It is the intention of the
          -----------------------------------                             
          parties that, subject to Governmental Requirements and pursuant to
          appropriate commercial arrangements to be negotiated in good faith,
          WGS, WGES and WELCO should share certain general and administrative
          services in order to provide such services in the most efficient and
          cost-effective manner.

          (a)  The parties acknowledge that they have committed to the DOE not
               to make any changes to the management teams of WGS or WGES except
               as provided in a Transition Agreement to be entered into between
               the Companies and the DOE (the "TRANSITION AGREEMENT").

          (b)  In order to support the performance of all DOD and DOE contracts,
               MK and BNSI will promote the free transferability of employees
               between the Companies, subject in all cases to applicable
               Governmental Requirements and the reasonable commercial
               requirements of the Companies and after consultation with the DOD
               or the DOE, as the case may be.

          (c)  Subject to the provisions of the Transition Agreement, if
               applicable, MK and BNSI will endeavor to keep the benefit
               arrangements for employees of the Companies similar to each
               other, portable and competitive.

          (d)  Subject at all times to the Governmental Requirements, WGS, WGES
               and WELCO shall establish an advisory committee made up of
               representatives chosen by each of the three Companies (the "HUMAN
               RESOURCES COMMITTEE") to discuss and provide non-binding
               recommendations to their respective presidents concerning the
               availability of WELCO personnel to assist WGS and WGES, taking
               into account the Governmental Requirements and the needs of the
               Companies.  The Human Resources Committee shall

               (i)    meet at least once each quarter, and at such other times
                      as they may mutually agree, for the purpose of discussing
                      anticipated personnel requirements and the availability of
                      such personnel for the ensuing 12 months, or for such
                      other periods as they may mutually agree,

               (ii)   make recommendations, if any, to their respective
                      presidents concerning the transfer or secondment of WELCO
                      personnel, subject to the Governmental Requirements, and

               (iii)  provide reports to the presidents of the Companies on such
                      personnel matters on at least a quarterly basis.

               The Companies shall cooperate in carrying out such
               recommendations of the Human Resources Committee as may be agreed
               to by each respective affected Company, subject to such changes
               as the Companies may agree upon and subject to the Governmental
               Requirements.  Notwithstanding the

               foregoing provisions of this Section 9.7(d) the recommendations
                                            -------------- 
               of the Human Resources Committee shall not be binding on the
               Companies, and none of the Companies shall be required to
               implement the recommended actions of the Human Resources
               Committee if they are on terms that are commercially unreasonable
               for that Company.

          (e)  Any personnel seconded to WGS or WGES pursuant to this Section 9
                                                                      ---------
               shall be seconded on a cost pass-through basis, including a
               reasonable allocation of overhead.

10.  TECHNOLOGY SHARING ARRANGEMENTS.
     ------------------------------- 

     10.1  General.  The parties recognize that the Companies and their
           -------                                                     
           subsidiaries have technology (including intellectual property) that
           may be useful to, or complementary of, the technology of each other.
           It is the intention of the parties that the full range of such
           technology be reasonably available to the Companies in providing
           services to their customers, particularly the DOE and the DOD, in
           accordance with this Section 10 and the Governmental Requirements,
                                ----------                                   
           including, without limitation, consistent with the technology
           transfer mission of DOE and other restrictions and conditions on
           licensing and technology transfer contained in the Covered Contracts
           specified in the Transition Agreement.

     10.2  Cooperation.  Subject to the Governmental Requirements and pursuant
           -----------                                                        
           to appropriate commercial arrangements to be negotiated in good
           faith, the parties will cause the Companies to cooperate to share
           relevant technology to best serve their client interests and goals;
           provided, however, that such sharing does not result in the
           disclosure of protected technology or intellectual property rights to
           third parties or the disclosure of classified information, special
           nuclear material, Unclassified Controlled Nuclear Information,
           Official Use Only, and/or export controlled data entrusted to or held
           by any Company except as permissible pursuant to the Governmental
           Requirements, including but not limited to the NISD and applicable
           U.S. government laws and regulations. Specific limitations on such
           interactions will be addressed in a Technology Control Plan and
           Security Control Agreement to be mutually agreed by the affected
           Companies and approved by the DOE and (as appropriate) the DOD. To
           ensure that relevant technology residing in WELCO is available to
           WGES and WGS in the performance of their business and contractual
           obligations, WELCO technology will be made available in accordance
           with the procedures set forth in Section 10.5.

     10.3. CBS Shared Technology Agreements.  Subject to the Governmental
           --------------------------------                              
           Requirements, the parties and their affiliates will enter into one or
           more technology sharing arrangements with CBS and certain of its
           affiliates, and certain third parties in connection with the
           transactions contemplated by the Asset Purchase Agreements (the "CBS
           SHARED TECHNOLOGY AGREEMENTS"). In order for WGS, WGES, and WELCO to
           obtain the benefit of the technology that is to be licensed
           thereunder, it will be necessary for them to enter into appropriate
           arrangements for the further sharing or licensing of such technology
           through sublicense arrangements which may require the prior approval
           of CBS (which may not be unreasonably withheld).

     10.4  WELCO Technology.  Recognizing that WELCO will possess technology and
           ----------------                                                     
           related resources that could benefit the delivery of goods and
           services under existing and future WGS and WGES contracts, BNSI will,
           and will cause WELCO to, make reasonable efforts to make available
           such technology (in compliance with the Governmental Requirements,
           confidentiality restrictions, and pre-existing contractual
           requirements) to support WGS and WGES, their subsidiaries, divisions
           and controlled affiliates, in the performance of U.S. government
           business. WELCO will own the AP600 technology (to the extent such
           technology is currently owned by CBS) and will abide by all
           requirements of the existing contracts regarding such technology that
           are assumed by WELCO pursuant to the ESBU Asset Purchase Agreement .

     10.5  Procedures for Technology Exchange.  Upon specific request and in
           ----------------------------------                               
           compliance with the Governmental Requirements, WELCO will make
           available to WGS and WGES such technology as shall be deemed
           reasonably necessary to support WGS or WGES in the performance of
           U.S. government business. Likewise, upon specific request and in
           compliance with the Governmental Requirements, WGS and WGES will make
           available to WELCO such technology as shall be deemed reasonably
           necessary to support WELCO's business activities. Such requests shall
           be made by the Company's representative on the Technology Exchange
           Committee ("TEC"), which shall be comprised of designated
           representatives from WGS, WGES, and WELCO. The TEC will meet at least
           quarterly, or more frequently if requested by a designated
           representative. Technology will be made available among the Companies
           in accordance with arms-length commercial terms and the Governmental
           Requirements. In the event technology resources requested are not
           reasonably available in WELCO or WGES, the members of TEC will work
           cooperatively to obtain the desired technology on acceptable
           commercial terms from other sources, consistent with the business
           goals of the entities represented on TEC. WELCO or WGES will not be
           required to provide technology on commercially unreasonable terms or
           contrary to their business interests.

           (a)  It is their intention to segregate the GESCO Business (which is
                in turn divided into the WGS Operations and the WGES
                Operations), and the ESBU Business by allocating them to the
                Companies as outlined in Section 6.
                                         --------- 

           (b)  It is their intention that the exposure of MK, MK-Delaware and
                their affiliates to liabilities arising from the GESCO Business
                or the ESBU Business, and the exposure of  BNFL, BNFL-USA , BNSI
                and their affiliates to liabilities arising from the GESCO
                Business be limited as set forth herein.

           (c)  In order to preserve the allocation of liabilities reflected by
                such actions, the parties agree that each of the parties and the
                Companies and their respective affiliates will be entitled to
                indemnification as set forth below.

     11.2  First and Second Tier Entities.  For the purposes of this Section 11

           (a)  MK, BNFL-USA, BNSI and, if applicable, their parent companies
                are referred to as "FIRST TIER ENTITIES" and

           (b)  WGNH, WGS, WGES and WELCO, and their respective subsidiaries,
                are referred to as "SECOND TIER ENTITIES".
 
     11.3  Indemnification.  With respect to any liability or claim that arises
           ---------------

           predecessor):

                ---

                will indemnify and defend  MK-Delaware, MK, their affiliates,
                BNFL, BNFL-USA, BNSI and their affiliates, WGNH and any other
                Second Tier Entities and their affiliates and hold them harmless
                against any loss or expense arising from such liability or claim
                (including reasonable attorneys' fees but excluding
                consequential damages) ("LOSSES"); provided that

               (i)  there shall be excluded from indemnification any Loss that
                    is reflected in a reduction in the value of any equity
                    interest in WGS held by MK or its affiliates or in the
                    amounts payable to BNSI under the WGS Agreement, and

               (ii) the assets of WGS that are to be used to make any such
                    indemnification payments shall in any event exclude its
                    membership interest in WGES and any dividends, distributions
                    or other payments received by WGS, or payable to WGS, with
                    respect to such interest.

               If the assets of WGS are insufficient to perform the required
               indemnification and defense BNSI and MK will make appropriate
               payments to each other and their respective affiliates such that
               MK and its affiliates, on the one hand, and BNSI and its
               affiliates, on the other hand, (taking into account their
               economic participation in the Second Tier Entities) share any
               Losses as provided in the WGS Agreement and otherwise on a 60/40

     -----------------                                                         
     cash bonus at the end of each fiscal year as determined by the Compensation
     Committee of the Board of Directors.  Management retains the discretion to
     pay between 50% and 150% of the target bonus amount, based on individual
     and/or group-level performance.  In accordance with our discussions, since
     you did not develop the 1999 performance targets or budgets, your
     performance will be evaluated based on both qualitative and quantitative
     factors; after 1999 the measures will be based primarily on group
     performance.

5.   Stock Options.  You will be granted options to purchase 200,000 shares of
     -------------                                                            
     the Company's common stock, under the Company's Stock Option Plan, at a
     price equal to the per share closing price of the Company's common stock as
     of the Effective Date.  The options shall vest 20% each year for five
     years.  Such options shall be subject to the terms and conditions of the
     Stock Option Plan and such additional conditions as the Compensation
     Committee may impose.

6.   Long-Term Incentive Plan:  I have asked the Compensation Committee of the
     ------------------------                                                 
     Board of Directors to approve a Long-Term Incentive Plan that would pay you
     and four other executives a bonus equal to one years base salary, if the
     Company achieves cumulative earnings per share of $2.02 for 1999 and 2000.
     It is not an easy target, but it is within the range of what the Company
     can do if all the operating groups (including Heavy Civil and Mining)
     perform well.  While the plan has not been finally approved by the
     Committee and Board, it is on the agenda for such approval at the January
     20 and 21 meeting.

7.   Fringe Benefits.  You will be entitled to the Company's standard relocation
     ---------------                                                            
     assistance when you move from Hopkinton, Massachusetts to Boise. Should
     your relocation costs exceed established maximums, these costs will be paid
     by the company.  You will be reimbursed for up to three trips back to
     Massachusetts during the first six months of your employment.  The Company
     will reimburse you for all reasonable and customary living expenses until
     your home in Massachusetts sells and your wife relocates to Boise.
     Additionally, you will be entitled to all other group plan and other
     benefits that are normally offered to regular full-time salaried employees:

[X]  401(k) Savings Plan: The company will match every dollar you contribute to
     the plan, up to 5% of your eligible compensation (maximum eligible
     compensation is $160,000);

[X]  group medical and dental plan and all other benefits as described in the
     Handbook for Salaried Employees (a copy of which is provided under separate
     cover), and all other group plans and benefits that are normally offered to
     regular full-time salaried employees.

[X]  Should you choose to continue your physicals at the Mayo Clinic, the
     company will bear the costs, including airfare and accommodations, every
     two years. The Company's standard policy is to provide an annual physical;
     should you, at some point, choose to have your physicals done in Boise, you
     will be provided the benefit pursuant to normal company policy.

[X]  Vacation: The Company has a paid time off (PTO) policy which would provide
     you with three weeks of paid time off during the first 5 years of MK
     service. Consistent with our discussions, you will be granted an additional
     week of paid time off on an exception basis during your first five years of
     MK service. The PTO accrual will not be modified to provide for this
     additional week; the time will be granted to you, outside the normal PTO,
     and granted to you as leave with pay.

[X]  Deferred Compensation Plan: The company has a deferred compensation plan
     for certain levels of management; as a senior executive of the company you
     would be eligible to participate. This plan allows for deferrals of up to
     50% of base salary and up to 100% of bonuses. I have provided, as an
     attachment, a calculation showing the annual payout that would result from
     a one-time $100,000 deferral at the present rate of interest provided in
     this plan (7.33% currently: Moody's rate plus 50 basic points, this rate is
     adjusted annually).

8.   Executive Life and Disability.  In addition to the fringe benefits set
     -----------------------------                                         
     forth in paragraph 7 herein, during your employment, you will be provided
     with supplemental benefits, at no cost to you, which shall result in the
     following levels of coverage, inclusive of any coverage provided by basic
     Company-sponsored benefits:

     a.  Pre-retirement (up to age 65) life insurance, equal to three times your
         annual base salary. . This is a whole life type policy funded over a
         seven-year period that provides a cash value should you remain employed
         beyond the seven-year period;

     b.  Post-retirement (age 65) life insurance, equal to one times your annual
         base salary as of the date of your retirement; and

     c.  Supplemental disability coverage which, when added to coverage from
         other Company-sponsored and government sources, will provide long-term
         disability income equal to 60% of the sum of your base salary plus your
         most recent annual bonus.

9.   Massachusetts Home: The company agrees to share in any loss you experience
     ------------------                                                        
     on the sale of your home as a result of your relocation to Boise. No risk
     of loss of two-thirds of any incurred costs to you, to-date, for the
     Massachusetts home custom furnishings and decorating that are not covered
     in the final sale price or not incorporated in an Idaho home.  MK agrees to
     pay two-thirds of the loss (on an audited basis, with the requisite
     documentation).  You will be eligible for participation in the "Buyer Value
     Option" program, described in my letter of December 2, 1998.


10.  Contingencies.  This employment offer must be contingent upon the following
     -------------
