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

1.  UNAUDITED INTERIM FINANCIAL STATEMENTS

  The accompanying condensed consolidated financial statements and related notes
of Morrison Knudsen Corporation and subsidiaries (the "Corporation") should be
read in conjunction with the audited consolidated financial statements and
related notes included in the Corporation's Annual Report on Form 10-K for the
year ended November 30, 1998. The comparative consolidated balance sheet and
related disclosures at November 30, 1998 have been derived from the audited
balance sheet and financial statement footnotes. The accompanying condensed
consolidated financial statements reflect all adjustments, consisting of normal
recurring adjustments, that in the opinion of management are necessary for a
fair presentation of the results of operations and cash flows for the interim
periods presented. The results of operations for the quarter ended February 26,
1999 are not necessarily indicative of the operating results to be expected for
the full year.

  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 dates and the reported amounts of revenue and cost during the
reporting periods. Actual results could differ in the near term from those
estimates. Due to uncertainties inherent in the process of estimating actual
amounts of revenue and costs on long-term contracts, results may vary from
estimates in the near term.

2.  ADOPTION OF NEW FISCAL YEAR

  The Corporation's fiscal year has historically ended on November 30. Effective
December 1, 1998, the Corporation adopted a 52/53 week fiscal year ending on the
Friday closest to November 30. The quarterly results of operations and cash
flows reported in the accompanying condensed financial statements for the
quarter ended February 26, 1999 includes the period from December 1, 1998
through February 26, 1999, and the quarter ended February 28, 1998 includes the
full three calendar months. The change in reporting period has not materially
affected comparability between the presented reporting periods.

3.  COMPREHENSIVE INCOME

  Effective December 1, 1998, the Corporation adopted Statement of Financial
Standards No. 130 Reporting Comprehensive Income ("SFAS No. 130"). SFAS No. 130
establishes standards for the reporting and display of comprehensive income and
its components but does not affect the principles currently used to measure
income. The standard requires disclosure of comprehensive income, which includes
all changes in stockholders' equity with the exception of additional investments
by stockholders or distributions to stockholders. Comprehensive income for the
Corporation includes net income, cumulative translation adjustments, unrealized
gains and losses on securities available for sale and minimum pension liability
adjustments. Comprehensive income for the quarter ended February 26, 1999 and
three months ended February 28, 1998 was as follows:

5.  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.

CONTRACT-RELATED MATTERS:

  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.

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 February
26, 1999 and November 30, 1998 $32,755 and $37,157, 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 to $3,000 in face amount of certain letters of credit that were
outstanding at February 26, 1999.

  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 $5,308 for the
bonds. No loss on the guarantee is probable and, accordingly, no accrual has
been made by the Corporation.

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. Trial has been set for August 16, 1999.

  Certain current and former officers, employees and directors of the
Corporation were named defendants in an action filed in the United States
District Court for the District of Idaho: John B. Blyler and Malcolm J. Corse v.
William J. Agee, et. al., Civil Action No. 97-0332-S-BLW. The  complaint
alleges, among other things, that the defendants breached certain fiduciary
duties.

  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.

6.  SUBSEQUENT EVENTS

ACQUISITION OF WESTINGHOUSE BUSINESSES:

  On March 22, 1999, the Corporation and British Nuclear Fuels, Ltd. ("BNFL")
acquired certain businesses (the "Westinghouse businesses") from CBS Corporation
(formerly known as Westinghouse Electric Corporation). The Westinghouse
businesses provide a wide range of products, services and technologies in the
government services and nuclear industries throughout the world.

  The acquisition is valued at approximately $1,100,000, including $200,000 in
cash and assumption of approximately $900,000 in liabilities. The Corporation's
share, however, is approximately $121,000 in cash, which was funded from new
revolving credit facilities totaling $250,000. BNFL's share is approximately
$79,000 in cash and the assumption of approximately $900,000 in specified
liabilities, commitments and obligations.

  Concurrent with the acquisition, the following three separate companies were
formed to acquire the operations of the Westinghouse businesses:

  (1) Westinghouse Government Services Company, LLC ("WGS"), a limited liability
company that provides defense-related operations and management services
primarily for the U.S. Departments of Energy and Defense, including the
production of tritium for national weapons programs and high-level waste
solidification, and employs over 11,200 employees. The company is wholly-owned
by the Corporation. BNFL retains a 40% passive economic interest in the profits
and losses and cash flows of Westinghouse Government Services.

  (2) Westinghouse Government Environmental Services Company, LLC ("WGES"), a
limited liability company that provides non-defense related governmental and
environmental services, including environmental remediation and waste management
services, and employs approximately 2,500 employees. This company is jointly
owned by the Corporation (60%) and BNFL (40%). The Corporation will have
management responsibility and control of WGS and WGES which will be organized
under the newly formed Westinghouse Government Services Group.

                                      I-9
<PAGE>
 
  (3) Westinghouse Electric Company, LLC ("WELCO"), a limited liability company
that provides commercial nuclear power technology with emphasis on service, fuel
and instrumentation and control technologies for operating nuclear power plants.
WELCO is also 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. Westinghouse Electric Company is
wholly-owned by BNFL and has approximately 4,000 employees. Subject to
governmental requirements and other applicable law, the Corporation will be the
preferred supplier to WELCO (and to WELCO's customers where WELCO has the right
to choose its customers' suppliers) for planning, constructing, demonstrating,
operating, maintaining, repairing and upgrading nuclear power generation
facilities and facilities in connection with WELCO's commercial nuclear and/or
steam operations.

CREDIT FACILITIES:

  On March 19, 1999, the Corporation replaced its prior bank credit facility
with new uncollateralized revolving credit facilities providing an aggregate
amount of $250,000 of borrowing capacity available to acquire the Westinghouse
businesses, for general corporate purposes, to support working capital
requirements and to support letters of credit and other potential acquisitions.
The new credit facilities consist of a $150,000 five-year facility which
provides for both revolving borrowings and the issuance of letters of credit,
and a $100,000 one-year facility which provides for revolving borrowings which
may be converted, at the Corporation's option, to a term loan having a maturity
of one year after the then current expiration of such facility. The term of each
facility may be extended annually for an additional year by mutual agreement of
the banks and the Corporation. The facilities' covenants require the maintenance
of financial ratios, and place limitations on guarantees, liens, investments,
dividends and other matters.

  The facilities provide for interest on loans, payable quarterly, at the
applicable LIBOR rate or the base rate, as defined, plus an additional margin.
The additional margin ranges from 1.25% to 2.00% for the LIBOR rate and 0.25% to
1.00% for the base rate, based on the ratio of earnings before interest, taxes,
depreciation and amortization to the Corporation's funded debt. On March 19,
1999, the Corporation paid $3,700 in underwriting fees to the banks and is
required to pay annual and quarterly commitment and letter of credit fees.

  The Corporation borrowed $120,000 under the facilities on March 22, 1999 in
connection with its funding requirements for the Westinghouse acquisition.

=======================================================

REVENUE AND GROSS PROFIT:

  Revenue for the quarter ended February 26, 1999 increased 9% compared to the
quarter ended February 28, 1998. The MK Contractors Group experienced an
increase in revenue principally due to major bridge retrofit work and highway
construction from the Heavy Civil Division and increased coal production from
the Mining Division. Industrial/Process volume also increased in the MK
Engineers and Constructors Group.

  Gross profit for the quarter ended February 26, 1999 increased $1.8 million
over the comparable period of 1998. The Corporation's gross profit as a percent
of revenue was 4.9% for the first quarter of 1999 and 1998. The gross profit of
MK Engineers and Constructors Group increased slightly over the first quarter of
1998 due to an increase in volume from the Industrial Process Division and a
decrease in group overhead resulting from staff and cost reductions related to
the reorganization and consolidation of the Environmental Group into MK
Engineers and Constructors in 1998. Gross profit from the MK Contractors Group
decreased primarily due to the impact of the milestone achievement for initial
profit recognition under the Corporation's accounting policies on a large
highway construction project in the first quarter of 1998. This decrease was
partially offset by the favorable resolution of royalty issues on certain mining
properties.

                                     I-11
<PAGE>
 
  At February 26, 1999, backlog of $2,685 million was comprised of $922 million
(34%) of revenue from fee-type contracts and $1,763 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 expense of $8.0 million for the quarter ended
February 26, 1999 increased $2.6 million from the comparable period in 1998
principally due to additional compensation expense of $1.7 million related to a
key executive retirement and a key executive recruitment, an increase in costs
related to the implementation of new computer systems and an increase in
professional expenses.

GOODWILL:

  Goodwill amortization for the first quarter of 1999 decreased slightly to $.8
million from $.9 million in the first quarter of 1998 as a result of
management's resolution during the fourth quarter of 1998 of the likelihood of
the future realization of the tax benefits of deductible temporary differences
and net operating loss carryforwards relating to Old MK. This resolution
resulted in an increase in deferred tax assets, a decrease in recorded goodwill
associated with Old MK at November 30, 1998, and a related reduction of
subsequent annual goodwill amortization of $.5 million. In connection with the
Corporation's recent acquisition of the Westinghouse businesses, an adjustment
to deferred tax assets and related goodwill associated with Old MK of $40 to $50
million, and a related reduction in future annual goodwill amortization expense
of $1.1 to $1.4 million, is expected. The amount of goodwill related to the
Westinghouse acquisition has not been determined.
 
INVESTMENT INCOME:

  The Corporation's investment income of $1.1 million in the first quarter of
1999 declined from $2.2 million in the first quarter of 1998, principally due to
interest recognized on claims for U.S. federal income tax refunds received in
January 1998 and a reduction in available corporate cash invested in a short-
term asset management account.

OTHER INCOME (EXPENSE):

  Other income (expense) of $2.2 million for the quarter ended February 26, 1999
resulted principally from favorable resolution of certain contingencies relating
to the sale of a former subsidiary of Old MK.

INCOME TAX EXPENSE:

  The effective tax rate for the first quarter of 1999 was 41.5% compared to 44%
in the first quarter of 1998, principally due to the eligibility of foreign tax
credits (as opposed to deductions) for use against U.S. federal income taxes 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 non-deductible expenses. The Corporation may realize a further
reduction in the effective income tax rate for the remainder of 1999 as a result
of the March 22, 1999 acquisition of the Westinghouse businesses and any
resulting: (1) reduction of nondeductible goodwill amortization expense relating
to the acquisition of Old MK, (2) eligibility of foreign tax credits from prior
years, and (3) additional pretax income expected from the Westinghouse
businesses. Additional reductions, if any, will be reflected in quarters ending
after the acquisition date. The anticipated reduction in the effective tax rate
is subject to, among other things, the Corporation's ability to meet or exceed
estimated pretax earnings levels for 1999.

FINANCIAL CONDITION

  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 bank credit facilities. 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                       (2,020)               (602)
- ----------------------------------------------------------------------

  Cash and cash equivalents decreased $38.2 million to $28.8 million at February
26, 1999 from $67.0 million at November 30, 1998. Operating activities used
$31.4 million in cash during the quarter ended February 26, 1999 for additional
joint-venture investments, incentive and bonus plan payments and working capital
requirements relating to construction and engineering contracts which the
Corporation expects to recover within the next two quarters. Cash provided by
operating activities during the first quarter of 1998 included $25.2 million of
income tax refunds and interest thereon. Cash provided from or used in operating
activities from period to period is affected by the mix, stage of completion and
commercial terms of engineering and construction contracts which are reflected
in changes in net operating assets and liabilities. Cash flow for the quarter
ended February 26, 1999 also reflects $3.6 million of net purchases of property
and equipment, $.6 million of net purchases of securities held for sale in
connection with the Corporation's self-insured risk management program, and $2.2
million used for the repurchase of 251,600 shares of the Corporation's common
stock for treasury.

  The Corporation received authorization in January 1998 to repurchase, in open
market transaction, block trades or otherwise up to 2 million shares of the
Corporation's outstanding common stock designed 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. Since program inception,
1,224,700 shares of common stock have been repurchased. Subject to market
conditions and other factors, these purchases may be continued, 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.

  The Corporation anticipates net capital expenditures for major construction
equipment of approximately $20 million during the remainder of 1999 for normal
replacement and to meet near-term equipment requirements for new work.

  As discussed in Note 6. "Subsequent Events -- Acquisition of Westinghouse
businesses and Credit facilities" of NOTES TO CONDENSED CONSOLIDATED FINANCIAL
STATEMENTS, ON MARCH 22, 1999 the Corporation and British Nuclear Fuels, Ltd.
("BNFL") acquired certain businesses from CBS Corporation (the "Westinghouse
businesses") which provide defense and non-defense related governmental and
environmental services. The Corporation's share of the purchase price was
approximately $121 million in cash, which was funded through borrowing under a
new $250

                                     I-13
<PAGE>
 
million uncollateralized revolving credit agreement entered into with certain
financial institutions on March 19, 1999. The agreement provides for a five-year
$150 million revolving credit and letter of credit facility and a one-year $100
million revolving credit facility which may be converted at the Corporation's
option into a term loan maturing one year after the then current expiration date
of such facility (the "Facilities"). In addition to funding the acquisition of
the Westinghouse businesses, the Facilities are available to support working
capital requirements and for general corporate purposes. The Facilities replace
the Corporation's prior $200 million bank credit facility. Depending on
conditions in capital markets and other factors, the Corporation may consider
the possible issuance of other long-term debt or other securities.

  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.

BACKLOG

Backlog of all uncompleted contracts at February 26, 1999 was $2,685 million,
compared with $2,680 million at November 30, 1998. New work awarded in the
quarter ended February 26, 1999 totaled $425 million compared with $440 million
for the quarter ended November 30, 1998.

THE YEAR 2000 ISSUE

  The Year 2000 issue results from the development of computer programs 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 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.

                                     I-14
<PAGE>
 
  The Corporation is in various "inventory," "assessment," "remediation" and
"testing/validation" phases with regard to its IT systems and non-IT devices. 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 February
26, 1999, the direct costs incurred by the Corporation to remediate Year 2000
issues were approximately $11.5 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

The United States Environmental Protection Agency has notified the Corporation
and approximately 20 other parties that each is a potentially responsible party
with regard to hazardous substances generated or disposed of at the Summitville
Mine Superfund Site. See Note 5. "Contingencies and Commitments -- Summitville
environmental matters" of Notes to Condensed Consolidated Financial Statements.

ADOPTION OF ACCOUNTING PRINCIPLE

Effective December 1, 1998, the Corporation adopted Statement of Financial
Accounting Standards No. 130 Reporting Comprehensive Income ("SFAS No. 130")
which establishes standards for the reporting and display of comprehensive
income and its components. SFAS No. 130 requires the reporting of total
comprehensive income in condensed financial statements of interim periods and
more expanded disclosures at year end. See Note 3. "Comprehensive Income" of
Notes to Condensed Consolidated Financial Statements.

ITEM 3. 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 February 26, 1999, the Corporation
had $11,873 of short-term investments classified as cash equivalents and $46,205
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 February 26,
1999, the Corporation had no outstanding debt obligations.

          Section 1.2.  Accounting Terms.  For purposes of this Agreement, all
accounting terms not otherwise defined herein shall have the meanings assigned
to such terms in conformity with GAAP.  Financial statements and other
information furnished to the Administrative Agent pursuant to Section 8.5 shall
be prepared in accordance with GAAP (as in effect at the time of such
preparation) on a consistent basis.  In the event any "Accounting Changes" (as
defined below) shall occur and such changes affect financial covenants,
standards or terms in this Agreement, then the Company, the Administrative Agent
and the Lenders agree to enter into negotiations in order to amend such
provisions of this Agreement so as to equitably reflect such Accounting Changes
with the desired result that the criteria for evaluating the financial condition
of the Company and its Subsidiaries shall be the same after such Accounting
Changes as if such Accounting Changes had not been made, and until such time as
such an amendment shall have been executed and delivered by the Company, the
Administrative Agent and the Required Lenders, (i) all financial covenants,
standards and terms in this Agreement shall be calculated and/or construed as if
such Accounting Changes had not been made and (ii) the Company shall prepare
footnotes to each compliance certificate and the financial statements required
to be delivered hereunder that show the differences between the financial
statements delivered (which reflect such Accounting Changes) and the basis for
calculating financial covenant compliance (without reflecting such Accounting
Changes).  "Accounting Changes" means: (a) changes in accounting principles
required by GAAP and implemented by the Company and any of its Subsidiaries; (b)
changes in accounting principles recommended by certified public accountants of
the Company or any of its Subsidiaries; or (c) changes in carrying value of the
Company's (or any of its Subsidiaries') assets, liabilities or equity accounts
resulting from the application  of purchase accounting principles.

SECTION 2.  THE REVOLVING CREDIT.

          Section 2.1.  General Terms.  Subject to all of the terms and
conditions hereof, the Lenders agree to extend a Revolving Credit to the Company
which may be availed of by the Company from time to time, be repaid and used
again, during the period from the date hereof to and including the Termination
Date.  The Revolving Credit may be utilized by the Company in the form of Loans
or Letters of Credit, all as more fully hereinafter set forth, provided that the
aggregate amount of Loans and Letters of Credit outstanding at any one time
shall not exceed the Commitments.  The maximum amount of the Revolving Credit
which each Lender agrees to extend hereunder shall be as set forth opposite its
name on Exhibit A attached hereto and made a part hereof (as the same shall be
deemed amended after giving effect to the Assignment Agreements referred to in
Section 12.12 hereof).  The obligations of the Lenders hereunder are several and
not joint and no Lender shall under any circumstance be obligated to extend
credit under the Revolving Credit in excess of its Commitment or its pro rata
share of the credit outstanding hereunder.

          Section 2.2.  The Loans.  Subject to all of the terms and conditions
hereof, the Revolving Credit may be availed of by the Company in the form of
loans (individually a "Loan" and collectively the "Loans").  Each Borrowing
shall be in a minimum amount of $1,000,000 and thereafter in integral multiples
of $100,000 (with LIBOR Portions being in a minimum amount of $5,000,000 and
thereafter in integral multiples of $500,000) and shall be made pro rata from
the Lenders in accordance with the amounts of their Commitments, except that
Borrowings may be requested in the amount of any drawing made with respect to
any Letter of Credit issued hereunder in order to satisfy the reimbursement
obligation then due.  All Loans made by each Lender shall be made against and
evidenced by a promissory note (individually a "Note" and collectively the
"Notes") in the form (with appropriate insertions) annexed hereto as Exhibit B.
Each Note shall be in the amount of the Commitment of the Lender to which it is
payable and shall mature on the Termination Date.

          Section 2.3.  Letters of Credit.

               (a)  General Terms. Subject to all of the terms and conditions
     hereof, the Revolving Credit may be availed of by the Company in the form
     of Letters of Credit issued to Persons other than Affiliates of the
     Company, provided that the U.S. Dollar Equivalent of any such Letter of
     Credit, when taken together with the U.S. Dollar Equivalent of all
     outstanding Loans and Letters of Credit, shall not exceed the Commitments
     then in effect. Notwithstanding anything to the contrary contained herein,
     all letters of credit issued by Bank of Montreal and Bank of America
     National Trust and Savings Association pursuant to the Prior Credit
     Agreement (such letters of credit being generally described on Exhibit E
     attached hereto) shall constitute "Letters of Credit" herein for all
     purposes of this Agreement and all applications and reimbursement
     agreements with respect to such letters of credit shall constitute
     "Applications" herein for all purposes of this Agreement, in each case to
     the same extent, and with the same force and effect, as if such Letters of
     Credit and Applications therefor had been issued at the request of the
     Company under this Agreement (without limiting the foregoing, from and
     after the date hereof, all reimbursement obligations and fees with respect
     to such letters of

                                     -14-
<PAGE>
 
     credit shall be paid as provided for in this Agreement). Subject to the
     last sentence of this Section 2.3(a), the amount of any Letter of Credit
     for all purposes of this Agreement shall be the maximum amount which could
     be drawn thereunder under any circumstances and over any period of time
     plus all unreimbursed drawings then outstanding with respect thereto. The
     Issuing Bank shall issue the Letters of Credit for the account of the
     Lenders and, accordingly, each Letter of Credit shall be deemed to utilize
     a pro rata share of the Commitment of each Lender. In the event the Company
     requests a letter of credit be issued in the name of a joint venture or
     other Affiliate of the Company, as applicant, for which the Company intends
     to be liable thereon for a fixed percentage of the reimbursement
     obligations and other liabilities owed to the Issuing Bank in connection
     therewith, such letter of credit may be issued hereunder provided that (i)
     the issuance thereof shall be at the sole discretion of the Issuing Bank on
     a case-by-case basis as and when any such letter of credit is requested,
     (ii) any portion of the reimbursement obligations or other liabilities owed
     to the Issuing Bank in connection therewith which are not assumed by the
     Company shall be for the sole risk and benefit of the Issuing Bank (i.e.,
     only the fixed percentage of such obligations and liabilities assumed by
     the Company shall be risk-participated to the Lenders under Section 2.3(e)
     below) and (iii) each such letter of credit shall constitute a "Letter of
     Credit" hereunder only to the extent of the Company's liability thereon.

          (b)  General Characteristics.  Each Letter of Credit issued hereunder
     shall expire not later than the Termination Date then in effect.  Each
     Letter of Credit issued hereunder shall be payable in U.S. Dollars or in an
     Available Foreign Currency, shall conform to the general requirements of
     the Issuing Bank for the issuance of letters of credit as to form and
     substance, and shall be a letter of credit which the Issuing Bank may
     lawfully issue.  If an Issuing Bank issues any Letter of Credit with an
     expiration date that is automatically extended unless such Issuing Bank
     gives notice that the expiration date will not so extend beyond its then
     scheduled expiration date, such Issuing Bank will give notice of such non-
     renewal before the time necessary to prevent such automatic extension if
     before such required notice date (i) the expiration date of such Letter of
     Credit if so extended would be after the Termination Date then in effect,
     (ii) the Commitments have been terminated, or (iii) a Default or an Event
     of Default exists and the Administrative Agent (acting with the consent or
     at the direction of the Required Lenders) has given the Issuing Bank
     instructions not to so permit the extension of the expiration date of such
     Letter of Credit.

          (c)  Applications and Agreements.  At the time the Company requests a
     Letter of Credit to be issued (or prior to the first issuance of a Letter
     of Credit, in the case of a continuing application), it shall execute and
     deliver to the Issuing Bank an application for such Letter of Credit in the
     form then prescribed by the Issuing Bank (the "Applications").  Anything
     contained in the Applications to the contrary notwithstanding (aa) the
     Company shall pay fees in connection with Letters of Credit only as set
     forth in Section 4 hereof, (ab) in the event that the Issuing Bank is not
     promptly reimbursed for the amount of any draft drawn under a Letter of
     Credit issued hereunder after notice to the Company that such draft has
     been received, the obligation of the Company to reimburse the Issuing Bank
     for the amount of such draft shall bear interest (which the 

                                     -15-
<PAGE>
 
     Company hereby promises to pay) from and after the date the draft is paid
     at a fluctuating rate per annum equal to (x) in the case of a drawing under
     a Letter of Credit denominated in U.S. Dollars or a Letter of Credit
     denominated in an Available Foreign Currency as to which the Issuing Bank
     has requested that the Company reimburse such drawing in U.S. Dollars, the
     sum of 2% plus the Base Rate from time to time in effect, and (y) in the
     case of a drawing under a Letter of Credit denominated in an Available
     Foreign Currency as to which the Issuing Bank has requested that the
     Company reimburse such drawing in the Available Foreign Currency in which
     such Letter of Credit is denominated, the sum of 2% plus the Overnight
     Foreign Currency Rate, and (ac) so long as no Event of Default has occurred
     and is continuing, the Issuing Bank will not call for the funding of a
     Letter of Credit prior to being presented with a draft or demand for
     payment thereunder (or, in the event the draft is a time draft, prior to
     its due date). The obligation of the Company to reimburse the Issuing Bank
     for all drawings under a Letter of Credit issued hereunder shall be
     governed by the Application related to such Letter of Credit, except that
     (i) the reimbursement by the Company of draws made under a Letter of Credit
     denominated in U.S. Dollars shall be made in U.S. Dollars, (ii) the
     reimbursement by the Company of draws made under a Letter of Credit
     denominated in an Available Foreign Currency shall be made by payment in
     U.S. Dollars of the U.S. Dollar Equivalent thereof, calculated on the date
     the Issuing Bank paid such draw, of the amount paid by the Issuing Bank
     pursuant to such draw, or, if the Issuing Bank shall elect by notice to the
     Company and the Administrative Agent by payment in the Available Foreign
     Currency which was paid by the Issuing Bank pursuant to such drawing in an
     amount equal to such drawing, and (iii) reimbursement in U.S. Dollars of a
     drawing paid shall be made to the Issuing Bank (with notice to the
     Administrative Agent) by no later than 1:00 p.m. (Chicago time) on the date
     when such drawing is paid and reimbursement in an Available Foreign
     Currency of a drawing paid shall be made to the Issuing Bank (with notice
     to the Administrative Agent) by no later than 1:00 p.m. local time at the
     place of payment or, if earlier, such local time as is necessary for such
     funds to be received and transferred to the Issuing Bank for same day value
     on the day such obligation is due; and any payment of a reimbursement
     obligation relating to a Letter of Credit received after such time shall be
     deemed to have been received by the Issuing Bank on the next Business Day.
     Notwithstanding any provision of this Agreement or any Application, in the
     event of any conflict or inconsistency between the terms of this Agreement
     and any Application, the terms of this Agreement shall control (without
     limiting the foregoing, the determination of the existence or non-existence
     of any Event of Default shall be determined by reference to this Agreement
     without regard to other events or circumstances which may be defined as
     events of default under any such Application).

          (d)  Change in Laws. If the Issuing Bank or any Lender shall determine
     in good faith that any applicable law, regulation or guideline (including,
     without limitation, Regulation D of the Board of Governors of the Federal
     Reserve System) or any interpretation of any of the foregoing by any
     governmental authority charged with the administration thereof or any
     central bank or other fiscal, monetary or other authority having
     jurisdiction over the Issuing Bank or such Lender (whether or not having
     the force of law) shall after the date hereof:

                                     -16-
<PAGE>
 
                    (aa) impose, modify or deem applicable any reserve, special
          deposit or similar requirements against the Letters of Credit or the
          Issuing Bank's or such Lender's or the Company's liability with
          respect thereto; or

                    (bb) impose on the Issuing Bank or such Lender any penalty
          with respect to the foregoing or any other condition regarding this
          Agreement, the Applications or the Letters of Credit;

     and the Issuing Bank or such Lender shall determine in good faith that the
     result of any of the foregoing is to increase the cost (whether by
     incurring a cost or adding to a cost) to the Issuing Bank or such Lender of
     issuing, maintaining or participating in the Letters of Credit hereunder
     (without benefit of, or credit for, any prorations, exemptions, credits or
     other offsets available under any such laws, regulations, guidelines or
     interpretations thereof), then the Company shall pay within 30 days
     following demand by the Issuing Bank or such Lender from time to time as
     specified by the Issuing Bank or such Lender such additional amounts as the
     Issuing Bank or such Lender shall in good faith determine are sufficient to
     compensate and indemnify it for such increased cost.  If the Issuing Bank
     or any Lender makes such a claim for compensation, it shall provide to the
     Company and the Administrative Agent a written explanation of the
     circumstances giving rise to such claim and a certificate setting forth
     such increased costs as a result of any event mentioned herein in
     reasonable detail and such certificate shall be deemed prima facie correct.
     Neither an Issuing Bank nor a Lender shall be entitled to compensation
     under this Section 2.3(d) with respect to any imposition for any period
     prior to the earlier of (i) the date it notifies the Company of the
     imposition giving rise to the request for compensation or (ii) the date
     which is 30 days prior to the date it becomes aware of the imposition
     giving rise to the request for compensation if the Company is notified of
     the adoption or change prior to the lapse of such 30-day period.

          (e)  Participations in Letters of Credit.  Each Lender shall
     participate on a pro rata basis in the Letters of Credit issued by the
     Issuing Banks, which participation shall automatically arise upon the
     issuance of each such Letter of Credit (such participations to ratably
     count against the Commitments of the Lenders when the Letters of Credit are
     issued).  Each Lender unconditionally agrees that in the event an Issuing
     Bank is not immediately reimbursed by the Company for the amount paid by
     such Issuing Bank on any draft presented to it under a Letter of Credit
     issued by it, then such Issuing Bank shall give prompt notice thereof to
     each Lender and in that event each Lender shall thereafter pay to such
     Issuing Bank (i) in the case of a reimbursement obligation payable in U.S.
     Dollars, an amount equal to such Lender's pro rata share (based on the
     percentage which its Commitment bears to the aggregate of the Commitments)
     of such unpaid reimbursement obligation, such payment to be made in lawful
     money in the United States, in immediately available funds at the Issuing
     Bank's lending office designated on its signature page hereof (or on its
     Assignment Agreement delivered pursuant to Section 12.12 hereof), together
     with interest on such amount accrued from the date the related payment was
     made by the Issuing Bank to the date of such payment by such participating
     Lender at a rate per annum equal to (x) from the date the related payment
     was made by the Issuing Bank to the date two (2) Business Days after
     payment by such 

                                     -17-
<PAGE>
 
     Lender is due hereunder, the Federal Funds Rate for each such day and (y)
     from the date two (2) Business Days after the date such payment is due from
     such Lender to the date such payment is made by such Lender, the Base Rate
     in effect for each such day and (ii) in the case of a reimbursement
     obligation payable in an Available Foreign Currency, an amount equal to
     such Lender's pro rata share (based on the percentage which its Commitment
     bears to the aggregate of the Commitments) of such unpaid reimbursement
     obligation, such payment to be made in the U.S. Dollar Equivalent of such
     Available Foreign Currency as then determined by the Issuing Bank, together
     with interest on such amount accrued from the date the related payment was
     made by the Issuing Bank to the date of such payment by the participating
     Lender at a rate per annum equal to (x) from the date the related payment
     was made by the Issuing Bank to the date two (2) Business Days after
     payment by such Lender is due hereunder, the U.S. Dollar Equivalent of the
     Overnight Foreign Currency Rate for each such day or, at the Issuing Bank's
     election, the Federal Funds Rate and (y) from the date two (2) Business
     Days after the date such payment is due from such Lender to the date such
     payment is made by such Lender, the sum of 1% plus the U.S. Dollar
     Equivalent of the Overnight Foreign Currency Rate for each such day or, at
     the Issuing Bank's election, the Base Rate in effect for each such day.
     Each such participating Lender shall thereafter be entitled to receive its
     pro rata share of each payment received in respect of the relevant
     reimbursement obligation and of interest paid thereon, with the Issuing
     Bank retaining its pro rata share as a Lender hereunder. In the event that
     any Lender fails to honor its obligation to reimburse an Issuing Bank for
     its pro rata share of the amount of any such draft, then in that event (i)
     the defaulting Lender shall have no right to participate in any recoveries
     from the Company in respect of such draft and (ii) all amounts to which the
     defaulting Lender would otherwise be entitled under the terms of this
     Agreement shall first be applied to reimbursing the Issuing Bank for the
     defaulting Lender's portion of the draft, together with interest thereon at
     the rate provided for herein. Upon reimbursement to the Issuing Bank of the
     amount advanced by the Issuing Bank in respect of the defaulting Lender's
     share of the draft, together with interest thereon, the defaulting Lender
     shall thereupon be entitled to its participation in such Issuing Bank's
     rights of recovery against the Company in respect of the draft paid by the
     Issuing Bank.

          (f) Notices.  Prior to the issuance of, or amendment to, any Letter of
     Credit, the relevant Issuing Bank shall give prompt telephone, telex or
     telecopy notice to the Administrative Agent of the proposed Letter of
     Credit specifying the effective date of such Letter of Credit or amendment,
     the amount, the beneficiary, and the expiration date of the proposed Letter
     of Credit.  The Administrative Agent shall promptly thereafter notify the
     Issuing Bank by telephone, telex or telecopy as to whether the amount of
     such Letter of Credit or expiry date with respect thereto would exceed any
     restrictions in this Section 2.3 on the amount of Letters of Credit to be
     issued hereunder or the expiry dates with respect thereto.  Upon the
     issuance of, or amendment to, any Letter of Credit hereunder, the relevant
     Issuing Bank shall promptly notify the Administrative Agent and the
     Administrative Agent shall thereafter promptly give telephone, telex or
     telecopy notice to each of the other Lenders of the issuance of, or
     amendment to, such Letters of Credit specifying the effective date of the
     Letter of Credit or amendment, the amount, the beneficiary, and the
     expiration date of the Letter of Credit, in each case as established

                                     -18-
<PAGE>
 
     originally or through the relevant amendment, as applicable, each Lender's
     pro rata participation in such Letter of Credit, and whether the Issuing
     Bank has classified the Letter of Credit as a Financial Letter of Credit or
     a Non-Financial Letter of Credit for regulatory reporting purposes.

          (g) Currency Determinations.  The Issuing Bank shall determine the
     U.S. Dollar Equivalent of each Letter of Credit and each obligation due
     with respect thereto, and a determination thereof by the Issuing Bank shall
     be conclusive and binding except in the case of manifest error.  The U.S.
     Dollar Equivalent of each reimbursement obligation with respect to a Letter
     of Credit drawn upon shall be calculated on the date the Issuing Bank pays
     on the drawing giving rise to such reimbursement obligation.  The U.S.
     Dollar Equivalent of each Letter of Credit shall be determined or
     redetermined, as applicable, on the date of issuance, increase or extension
     of such Letter of Credit and on the first day of each month thereafter, and
     each Issuing Bank shall promptly notify the Administrative Agent of the
     determination thereof.  At the request of any Lender, the Issuing Bank
     shall redetermine the U.S. Dollar Equivalent of any Letter of Credit at
     such times, and from time to time, as may be requested.

     Section 2.4.  Manner of Borrowing. The Company shall give written or
telephonic notice to the Administrative Agent (which notice shall be irrevocable
once given and, if given by telephone, shall be promptly confirmed in writing)
by no later than 12:00 noon (Chicago time) on the date the Company requests that
any Borrowing of Loans be made to it under the Commitments, and the
Administrative Agent shall promptly notify each Lender of the Administrative
Agent's receipt of each such notice. Each such notice shall specify the date of
the Borrowing of Loans requested (which must be a Business Day, and which date
shall be at least three (3) Business Days subsequent to the date of such notice
in the case of any Borrowing of Loans constituting a LIBOR Portion) and the
amount of such Borrowing. Each Borrowing of Loans shall initially constitute
part of the applicable Base Rate Portion except to the extent the Company has
otherwise timely elected that such Borrowing constitute part of a LIBOR Portion
as provided in Section 3 hereof. The Company agrees that the Administrative
Agent may rely upon any written or telephonic notice given by any person the
Administrative Agent in good faith believes is an Authorized Representative
without the necessity of independent investigation and, in the event any
telephonic notice conflicts with the written confirmation, such telephonic
notice shall govern if the Administrative Agent and the Lenders have acted in
reliance thereon. The Lenders undertake to endeavor in good faith to honor on a
same day basis Borrowing requests received later than 12:00 noon (Chicago time)
but shall incur no liability to the Company if it is not reasonably practical
for them to honor such requests on a same day basis. Not later than 1:00 p.m.
(Chicago time) on the date specified for any Borrowing of Loans to be made
hereunder, each Lender shall make the proceeds of its Loan comprising part of
such Borrowing available to the

                                     -19-
<PAGE>
 
Administrative Agent in Chicago, Illinois in immediately available funds.
Subject to the provisions of Section 7 hereof, the proceeds of each Loan shall
be made available to the Company at the principal office of the Administrative
Agent in Chicago, Illinois, in immediately available funds, upon receipt by the
Administrative Agent from each Lender of its pro rata share of such Borrowing.
Unless the Administrative Agent shall have been notified by a Lender prior to
1:00 p.m. (Chicago time) on the date a Borrowing is to be made hereunder that
such Lender does not intend to make its pro rata share of such Borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender has made such share available to the Administrative Agent on such
date and the Administrative Agent may (but shall not be obligated to) in
reliance upon such assumption make available to the Company a corresponding
amount. If such corresponding amount is not in fact made available to the
Administrative Agent by such Lender and the Administrative Agent has made such
amount available to the Company, the Administrative Agent shall be entitled to
receive such amount from such Lender forthwith upon its demand, together with
interest thereon in respect of each day during the period commencing on the date
such amount was made available to the Company and ending on but excluding the
date the Administrative Agent recovers such amount at a rate per annum equal to
(x) from the date the related payment was due to the Administrative Agent to the
date two (2) Business Days after the date such payment was due, the Federal
Funds Rate for such day (or in the case of a day which is not a Business Day,
then for the preceding day) and (y) thereafter until payment of such amount is
received by the Administrative Agent from such Lender, the Base Rate in effect
for each such day.

SECTION 3.  INTEREST.

          Section 3.1.  Options.  Subject to all of the terms and conditions of
this Section 3, portions of the principal indebtedness evidenced by the Notes
(all of the indebtedness evidenced by the Notes bearing interest at the same
rate for the same period of time being hereinafter referred to as a "Portion")
shall, at the option of the Company, bear interest with reference to the Base
Rate (the "Base Rate Portions") or with reference to the Adjusted LIBOR ("LIBOR
Portions"), and Portions shall be convertible from time to time from one basis
to the other.  All of the indebtedness evidenced by the Notes which is not part
of a LIBOR Portion shall constitute a single Base Rate Portion.  All of the
indebtedness evidenced by the Notes which bears interest with reference to a
particular Adjusted LIBOR for a particular Interest Period shall constitute a
single LIBOR Portion.  Anything contained herein to the contrary
notwithstanding, there shall not be more than eight (8) LIBOR Portions
applicable to any Note outstanding at any one time and each Lender shall have a
ratable interest in each Portion based on its Commitment percentage thereof.
The Company promises to pay interest on each Portion at the rates and times
specified in this Section 3.

          Section 3.2.  Base Rate Portion.  Each Base Rate Portion shall bear
interest (which the Company promises to pay at the times herein provided) at the
rate per annum determined by adding the Applicable Margin to the Base Rate as in
effect from time to time.  Interest on the Base Rate Portions shall be payable
quarterly in arrears on the first day of each March, June, September and
December in each year and at maturity of the applicable Notes, and interest
after maturity shall be due and payable upon demand.

          Section 3.3.  LIBOR Portions.  Each LIBOR Portion shall bear interest
(which the Company promises to pay at the times herein provided) for each
Interest Period selected therefor at a rate per annum equal to the Adjusted
LIBOR for such Interest Period plus the Applicable Margin.  Interest on each
LIBOR Portion shall be due and payable on the last day of each Interest Period
applicable thereto and, if an Interest Period is longer than three (3) months,
then at the end of each three (3)-month period and at the end of such Interest
Period, and interest after maturity shall be due and payable upon demand.  The
Company shall give written or telephonic notice to 

                                     -20-
<PAGE>
 
the Administrative Agent (which notice shall be irrevocable once given and, if
given by telephone, shall be promptly confirmed in writing) on or before 12:00
noon (Chicago time) on the third Business Day preceding the end of an Interest
Period applicable to a LIBOR Portion whether such LIBOR Portion is to continue
as a LIBOR Portion, in which event the Company shall notify the Administrative
Agent of the new Interest Period selected therefor, and in the event the Company
shall fail to so notify the Administrative Agent, such LIBOR Portion shall
automatically be converted into and added to the Base Rate Portion as of and on
the last day of such Interest Period. The Administrative Agent shall promptly
notify each Lender of each notice received from the Company pursuant to the
foregoing provisions. Anything contained herein to the contrary notwithstanding,
the obligation of the Lenders to create or continue any LIBOR Portion or to
convert any part of the Base Rate Portion into a LIBOR Portion shall be
conditioned upon the fact that at the time no Default or Event of Default shall
have occurred and be continuing, except that during the existence of a Default
(but not an Event of Default) the Company may request the continuation of any
LIBOR Portion into another LIBOR Portion with an Interest Period not in excess
of one (1) month.

          Section 3.4.  Computation.  All interest on the Notes and all fees,
charges and commissions due hereunder shall be computed on the basis of a year
of 360 days for the actual number of days elapsed, except that interest on the
Base Rate Portion and reimbursement obligations with respect to Letters of
Credit shall be computed on the basis of a year of 365 or 366 days (as the case
may be) for the actual number of days elapsed.

          Section 3.5.  Manner of Rate Selection.  The Company shall notify the
Administrative Agent by 12:00 noon (Chicago time) at least three (3) Business
Days prior to the date upon which it requests that any LIBOR Portion be created
or that any part of the Base Rate Portion be converted into a LIBOR Portion
(such notice to specify in each instance the amount thereof and the Interest
Period selected therefor) and the Administrative Agent shall promptly advise
each Lender of each such notice.  If any request is made to convert a LIBOR
Portion into the Base Rate Portion, such conversion shall only be made so as to
become effective as of the last day of the Interest Period applicable thereto.
All requests for the creation, continuance or conversion of Portions under this
Agreement shall be irrevocable.  Such requests may be written or telephonic
(provided that if such notice is given by telephone, the Company shall promptly
confirm such notice to the Administrative Agent in writing), and the
Administrative Agent is hereby authorized to honor telephonic requests for
creations, continuances and conversions received by it from any person the
Administrative Agent reasonably believes to be an Authorized Representative, the
Company hereby indemnifying the Administrative Agent and the Lenders from any
liability or loss ensuing from so acting.  The Company acknowledges that, in
connection with acknowledgment agreements entered into pursuant to Section 4.11
hereof and Assignment Agreements entered into pursuant to Section 12.12(a)
hereof entered into at any time prior to the earlier of (i) 30 days after the
close of the primary syndication as reasonably determined and established by the
Administrative Agent and (ii) six (6) months after the date hereof, any LIBOR
Portions which are required to be prepaid by the Administrative Agent in
connection therewith (in order for Loans and credit risks with respect to
Letters of Credit then outstanding to be shared ratably by the Lenders in
accordance with their adjusted Commitments) shall be accompanied by any payments
required to be paid to the Lenders under Section 3.6 hereof.

                                     -21-

     Section 3.6.  Funding Indemnity. In the event any Lender shall incur any
loss, cost or expense (including, without limitation, any loss, cost or expense
incurred by reason of the liquidation or re-employment of deposits or other
funds acquired by such Lender to fund or maintain any LIBOR Portion or the
relending or reinvesting of such deposits or amounts paid or prepaid to such
Lender, but excluding any loss of profit) as a result of:

          (a) any payment or prepayment of a LIBOR Portion on a date other than
     the last day of its Interest Period for any reason, whether before or after
     default, and whether or not such payment is required by any of the
     provisions of this Agreement;

          (b) any failure (because of a failure to meet the conditions of
     Section 7 hereof or otherwise) by the Company to create, borrow, continue
     or effect by conversion a LIBOR Portion on the date specified in a notice
     given pursuant to this Agreement hereof; or

          (c) any failure by the Company to make any payment of principal on any
     LIBOR Portion when due (whether by acceleration, mandatory prepayment or
     otherwise),

then, upon the demand of such Lender, the Company shall pay to such Lender such
amount as will reimburse such Lender for such loss, cost or expense.  If any
Lender makes such a claim for compensation, it shall provide to the Company a
certificate executed by an officer of such Lender setting forth the amount of
such loss, cost or expense in reasonable detail (including an explanation of the
basis for and the computation of such loss, cost or expense) and such
certificate shall be deemed prima facie correct.

     Section 3.7.  Change of Law. Notwithstanding any other provisions of this
Agreement or any Note, if at any time any change in applicable law or regulation
or in the official interpretation thereof makes it unlawful for any Lender to
make or continue to maintain LIBOR Portions or to give effect to its obligations
to make LIBOR Portions available as contemplated hereby, such Lender shall
promptly give notice thereof to the Company and the Administrative Agent and
such Lender's obligations to make or maintain LIBOR Portions under this
Agreement shall be suspended until it is no longer unlawful for such Lender to
make or maintain LIBOR Portions. To the extent it is unlawful for any such
Lender to maintain any such LIBOR Portions, the Company shall prepay on demand
the outstanding principal amount of any such affected LIBOR Portions, together
with all interest accrued thereon and all other amounts then due and payable to
such Lender under this Agreement; provided, however, subject to all of the terms
and conditions of this Agreement, the Company may then elect to convert the
principal amount of the affected LIBOR Portion from such Lender into the Base
Rate Portion from such Lender that shall not be made ratably by the Lenders but
only from such affected Lender. During the period when it is unlawful for any
Lender to make LIBOR Portions, Loans shall continue to be made in such a manner
so that the percentage of each Lender's Commitment in use is identical, but the
Lenders affected by such illegality shall make their share of each Borrowing
which has been requested in the form of a LIBOR Portion available in the form of
a Base Rate Portion. Each Lender agrees (to the extent consistent with its
internal policies) to designate a different lending office if such designation
would avoid the illegality described in this Section 3.7; provided, however,
that such designation need not be made if it would result in any additional
costs, expenses or risks to such

                                     -22-
<PAGE>
 
Lender that are not reimbursed by the Company pursuant hereto or would, in the
reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

     Section 3.8.  Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any LIBOR Portion the Administrative Agent determines that deposits in United
States Dollars (in the applicable amounts) are not being offered to it or to
banks generally in the offshore eurodollar market for such Interest Period, then
the Administrative Agent shall forthwith give notice thereof to the Company and
the Lenders, whereupon until the Administrative Agent notifies the Company that
the circumstances giving rise to such suspension no longer exist, the
obligations of the Lenders to make any further LIBOR Portions available shall be
suspended.

     Section 3.9.  Increased Cost and Reduced Return. If, on or after the date
hereof, the adoption of any applicable law, rule or regulation, or any change
therein, or any change in the official interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its lending office) with any request or directive (whether or not having the
force of law) of any such authority, central bank or comparable agency:

          (a) shall subject any Lender (or its lending office) to any charges of
     any kind (other than Withholding Taxes covered by Section 4.10 hereof) with
     respect to its interest in the LIBOR Portions, its Note or its obligation
     to make LIBOR Portions available, or shall change the basis of taxation of
     payments to any Lender (or its lending office) of the principal of or
     interest on LIBOR Portions or any other amounts due under this Agreement in
     respect of its LIBOR Portions or its obligation to make LIBOR Portions; or

          (b) shall impose, modify or deem applicable any reserve, special
     deposit or similar requirements (including, without limitation, any such
     requirement imposed by the Board of Governors of the Federal Reserve
     System, but excluding any such requirement included in an applicable
     Eurodollar Reserve Percentage) against assets of, deposits with or for the
     account of, or credit extended by, any Lender (or its lending office) or
     shall impose on any Lender (or its lending office) or the offshore
     interbank market any other condition affecting LIBOR Portions, its Note or
     its obligation to make LIBOR Portions available;

and the result of any of the foregoing is to increase the cost to such Lender
(or its lending office) of making or maintaining any LIBOR Portion, or to reduce
the amount of any sum received or receivable by such Lender (or its lending
office) under this Agreement or under its Note with respect thereto, by an
amount deemed by such Lender to be material, then, within 30 days after demand
by such Lender (with a copy to the Administrative Agent), the Company shall pay
to such Lender such additional amount or amounts as will compensate such Lender
for such increased cost or reduction.  A certificate of any Lender claiming
compensation under this Section 3.9 and setting forth the additional amount or
amounts in reasonable detail (including an explanation of the basis therefor and
the computation of such amount) to be paid to it hereunder shall be deemed prima
facie correct.  In determining such amount, such Lender may use reasonable
averaging and attribution methods.  A Lender shall not be entitled to
compensation 

                                     -23-
<PAGE>
 
under this Section 3.9 with respect to any adoption or change for any period
prior to the earlier of (i) the date it notifies the Company of the adoption or
change giving rise to the request for compensation or (ii) the date which is 30
days prior to the date it becomes aware of the adoption or change giving rise to
the request for compensation if the Company is notified of the adoption or
change prior to the lapse of such 30-day period.

     Section 3.10.  Lending Offices. Each Lender may, at its option, elect to
make its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof (each a "lending office") or at such other of
its branches, offices or affiliates as it may from time to time elect and
designate in a notice to the Company and the Administrative Agent (but such
funds shall in any event be made available to the Company at the office of the
Administrative Agent as herein provided for).

     Section 3.11.  Discretion of Banks as to Manner of Funding. Notwithstanding
any other provision of this Agreement, each Lender shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations under this Agreement (including, without limitation, calculations
under Sections 3.6 and 3.9 hereof) shall be made as if each Lender had actually
funded and maintained its interest in each LIBOR Portion through the purchase of
deposits in the offshore interbank market having a maturity corresponding to
such LIBOR Portion's Interest Period and bearing an interest rate equal to LIBOR
for such Interest Period.

Section 4.  Fees, Payments, Reductions, Applications, Notations and Extensions.

     Section 4.1.   Commitment Fee. For the period from the date hereof to and
including the Termination Date, the Company shall pay to the Administrative
Agent for the ratable account of the Lenders a commitment fee at the Applicable
Margin on the average daily unused amount of the Commitments hereunder (provided
that, if the average daily unused amount of the Commitments for the most
recently completed three (3) month period (or such shorter period from the date
of this Agreement through the first payment date thereof) plus the daily unused
amount of the commitments available under the 364-Day Credit Agreement for such
period is greater than 50% of the Commitments available hereunder and the
commitments available under the 364-Day Credit Agreement for such period, then
such fee shall be paid at .125% plus the Applicable Margin for the commitment
fee), such fee to be payable quarterly in arrears on the first day of each
March, June, September and December in each year to and including, and on, the
Termination Date.

     Section 4.2.   Letter of Credit Fees.

     (a)  Shared Fees. The Company shall pay to the Administrative Agent for the
ratable account of the Lenders a letter of credit fee computed at the Applicable
Margin on the maximum amount of the Letters of Credit from time to time
outstanding, such fee to be paid quarterly in arrears on the first day of each
March, June, September and December in each year to and including, and on, the
Termination Date.

                                     -24-
<PAGE>
 
          (b) Issuing Bank Fronting Fees.  On the date of issuance of each
Letter of Credit, and as a condition thereto, the Company shall pay to the
relevant Issuing Bank a non-refundable letter of credit issuance fee in the
amount equal to .10% of the amount of the relevant Letter of Credit to be
issued.  In addition, the Company further agrees to pay each Issuing Bank for
its own account such amendment, processing and transaction fees and charges as
the Issuing Bank from time to time customarily imposes in connection with any
amendment, cancellation, negotiation and/or payment of Letters of Credit issued
by such Issuing Bank and draft drawn thereunder.

          Section 4.3.  Administrative Agent's Fees.  On the date hereof, and on
the date occurring on each anniversary of the date hereof (excluding the
Termination Date) when any credit or commitment to extend credit is outstanding
hereunder, the Company shall pay to the Administrative Agent, for its own use
and benefit, such fees as set forth in the administrative agent's fee letter
dated the date hereof, as such fees may be amended by the Company and the
Administrative Agent from time to time.

          Section 4.4.  Underwriting Fees.  The Company shall pay to the Lead
Arrangers, Book Managers, and Syndication Agents such underwriting, acceptance
and ticking fees as set forth in the Fee and Structuring Letter.

          Section 4.5.  Payments.  (a)  Maturity.  The Company shall repay all
Loans in full on the Termination Date, together with all accrued but unpaid
interest thereon.

          (b) Mandatory Prepayments.  In the event that at any time the
aggregate U.S. Dollar Equivalent of Letters of Credit and Loans then outstanding
exceeds the Commitments then in effect, the Company shall immediately upon
demand pay over the amount of the excess to the Administrative Agent to be
applied against the Loans until paid in full with any excess to be held as
collateral security for the Letters of Credit and the obligations of the Company
with respect thereto.

          (c) Optional Prepayments.  The Company shall have the privilege of
prepaying without premium or penalty and in whole or in part (but, if in part,
then in an amount not less than $1,000,000) (or such lesser amount as will
prepay the Loans in full) the Notes at any time, each such prepayment to be made
by the payment of the principal amount to be prepaid, any amount due the Lenders
under Section 3.6 hereof (any failure of the Administrative Agent or the Lenders
to require payment of any amount due under Section 3.6 not to preclude a later
demand that the amount so due be paid) and, in the case of a prepayment which
prepays the Notes in full after which the Commitments are no longer outstanding,
accrued interest thereon to the date fixed for prepayment.

          Section 4.6.  Terminations.  The Company shall have the privilege at
any time and from time to time upon five (5) Business Days prior notice to the
Administrative Agent (which shall promptly notify the Lenders) to  ratably
terminate the Commitments in whole or in part (but, if in part, then in a
minimum amount of $1,000,000), provided that the Commitments may not be reduced
to an amount less than the aggregate principal amount of Loans and Letters of
Credit then outstanding.  No termination of the Commitments may be reinstated
unless otherwise agreed to in writing by the Lenders.

          Section 4.7.  Place and Application.  Except as otherwise provided in
Section 2.3 with respect to Letters of Credit issued by a Lender other than the
Administrative Agent, all payments of principal, interest and fees shall be made
to the Administrative Agent at its office at 115 South LaSalle Street, Chicago,
Illinois (or at such other place as the Administrative Agent may specify) in
immediately available and freely transferable funds at the place of payment.
All payments due from the Company hereunder shall be made without set-off or
counterclaim and without reduction for, and free from, any and all present or
future taxes, levies, imposts, duties, fees, charges, deductions, withholdings,
restrictions or conditions of any nature imposed by any government or political
subdivision or taxing authority thereof.  Except as otherwise provided in
Section 2.3 with respect to Letters of Credit, payments received by the
Administrative Agent after 1:00 p.m. (Chicago time) shall be deemed received as
of the opening of business on the next Business Day.  Except as otherwise
provided in this Agreement, all payments shall be received by the Administrative
Agent for the ratable account of the Lenders, and shall be promptly distributed
by the Administrative Agent ratably to the Lenders except that payments which
pursuant to the terms hereof are for the use and benefit of the Administrative
Agent shall be retained by it for its own account and payments received to
reimburse an Issuing Bank or a Lender for a fee or cost peculiar to that Issuing
Bank or Lender, as the case may be, shall be remitted to it.  Unless the Company
otherwise directs, principal payments on the Notes shall be first applied to the
Base Rate Portion and then to the LIBOR Portions in the order in which their
Interest Periods expire.  Reimbursements of drawings under Letters of Credit
shall be promptly remitted to the relevant Issuing Bank except to the extent the
Lenders have previously reimbursed the Issuing Bank for the drawing in question.

          Anything contained herein to the contrary notwithstanding, all
payments and collections received in respect of the indebtedness evidenced by
the Notes or the Applications by the Administrative Agent or any of the Lenders
after an Event of Default has occurred and is continuing shall be distributed as
follows:
               (a) first, to the payment of any outstanding costs and expenses
          incurred by the Administrative Agent in protecting, preserving or
          enforcing rights under the Loan Documents and in any event including
          all costs and expenses of a character which the Company has agreed to
          pay under Section 12.10 hereof (such funds to be retained by the
          Administrative Agent for its own account unless it has previously been
          reimbursed for such costs and expenses by the Lenders, in which event
          such amounts shall be remitted to the Lenders to reimburse them for
          payments theretofore made to the Administrative Agent); and

               (b) second, to the remaining Obligations (including amounts be
          held as collateral security for the Letters of Credit in an amount
          equal to the aggregate undrawn balance thereof, with the funds so held
          to, if the Company so requests, be invested in short-term high-grade
          debt securities, acceptable to and held by and pledged to the
          Administrative Agent (it being understood that the balance of such
          investments and any earnings attributable thereto shall, after the
          payment and satisfaction in full of any and all obligations owing to
          the Administrative Agent and the Lenders hereunder and under the other
          Loan Documents and after the expiration of all Letters of Credit, be
          returned to the

                                     -26-
<PAGE>
 
          Company or to whoever may be lawfully entitled thereto)), ratably in
          accordance with the amounts owed to or for the account of the
          Administrative Agent and the Lenders.

          Section 4.8.  Notations and Requests.  All advances made against the
Notes shall be recorded by the Lenders on their books or, at their option in any
instance, endorsed on the reverse side of the Notes and the unpaid principal
balances so recorded or endorsed by the Lenders shall be prima facie evidence in
any court or other proceeding brought to enforce the Notes of the principal
amount remaining unpaid thereon.  Prior to any negotiation of any Note, the
Lender holding such Note shall endorse thereon the principal amount remaining
unpaid thereon.

          Section 4.9.  Capital Adequacy.  If any Lender shall determine that
any applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof or compliance by such Lender (or its
lending office) with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on such Lender's capital as a consequence of its obligations hereunder or the
Letters of Credit or credit extended by it hereunder to a level below that which
such Lender could have achieved but for such law, rule, regulation, change or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy) by an amount deemed by such Lender to be material, then from
time to time as specified by such Lender the Company shall pay such additional
amount or amounts as will compensate such Lender for such reduction in rate of
return.  A certificate of any Lender claiming compensation under this Section
and setting forth the additional amount or amounts to be paid to it hereunder in
reasonable detail shall be deemed prima facie correct.  In determining such
amount, such Lender may use any reasonable averaging and attribution methods.  A
Lender shall not be entitled to compensation under this Section with respect to
any change, adoption or interpretation (a "Change") for any period prior to the
earlier of (i) the date it notifies the Company of the Change or (ii) the date
which 30 days prior to the date such Lender obtains actual knowledge of the
Change giving rise to the request for compensation if the Company is notified of
the Change prior to the lapse of such 30-day period.  Each Lender and the
Administrative Agent shall use reasonable efforts to minimize the cost imposed
on the Company in respect of any such increased capital requirement and shall
compute the assessment of any such cost related to such increased capital on a
nondiscriminatory basis among the Company, on the one hand, and other borrowers
to which it applies, on the other hand, and neither such Lender nor any
corporation controlling such Lender nor the Administrative Agent shall be
entitled to demand compensation or be compensated for any increased capital
requirement from the Company hereunder in excess of the amount so computed.

          Section 4.10.  Withholding Taxes.  (a) Payments Free of Withholding.
Except as otherwise required by law and subject to Section 4.10(b) hereof, each
payment by the Company under this Agreement or the other Loan Documents shall be
made without withholding for or on account of any present or future taxes (other
than overall net income taxes on the recipient) imposed by or within the
jurisdiction in which the Company is domiciled, any jurisdiction from which the
Company makes any payment, or (in each case) any political subdivision or taxing
authority thereof or therein; provided, however, that the Company shall not be
required to indemnify or 

                                     -27-
<PAGE>
 
gross up the payments to any Lender under this Section 4.10(a) in respect of
United States federal withholding tax to the extent that the obligation to
indemnify or gross up such payments would not have arisen but for such Lender's
failure to comply with Section 4.10(b). If any such withholding is so required,
the Company shall make the withholding, pay the amount withheld to the
appropriate governmental authority before penalties attach thereto or interest
accrues thereon and forthwith pay such additional amount as may be necessary to
ensure that the net amount actually received by each Lender and the
Administrative Agent free and clear of such taxes (including such taxes on such
additional amount) is equal to the amount which that Lender or the
Administrative Agent (as the case may be) would have received had such
withholding not been made. If the Administrative Agent or any Lender pays any
amount in respect of any such taxes, penalties or interest, the Company shall
reimburse the Administrative Agent or such Lender for that payment on demand in
the currency in which such payment was made. If the Company pays any such taxes,
penalties or interest, it shall deliver official tax receipts evidencing that
payment or certified copies thereof to the Lender or Administrative Agent on
whose account such withholding was made (with a copy to the Administrative Agent
if not the recipient of the original) on or before the thirtieth day after
payment.

          (b) U.S. Withholding Tax Exemptions.  Each Lender that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) shall
submit to the Company and the Administrative Agent on or before the date the
initial Loans are is made hereunder or, if later, the date such financial
institution becomes a Lender hereunder, two duly completed and signed copies of
(i) either Form 1001 (relating to such Lender and entitling it to a complete
exemption from withholding under the Code on all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents and the Obligations) or
Form 4224 (relating to all amounts to be received by such Lender, including
fees, pursuant to the Loan Documents and the Obligations) of the United States
Internal Revenue Service or (ii) solely if such Lender is claiming exemption
from United States withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any successor
form prescribed by the Internal Revenue Service, and a certificate representing
that such Lender is not a bank for purposes of Section 881(c) of the Code, is
not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the
Code) of the Company and is not a controlled foreign corporation related to the
Company (within the meaning of Section 864(d)(4) of the Code).  Thereafter and
from time to time, each Lender shall submit to the Company and the
Administrative Agent such additional duly completed and signed copies of one or
the other of such Forms (or such successor forms as shall be adopted from time
to time by the relevant United States taxing authorities) and such other
certificates as may be (i) requested by the Company in a written notice,
directly or through the Administrative Agent, to such Lender and (ii) required
under then-current United States law or regulations to avoid or reduce United
States withholding taxes on payments in respect of all amounts to be received by
such Lender, including fees, pursuant to the Loan Documents or the Obligations.
Upon the request of the Company or the Administrative Agent, each Lender that is
a United States person (as such term is defined in Section 7701(a)(30) of the
Code) shall submit to the Company and the Administrative Agent a certificate to
the effect that it is such a United States person.

          (c) Inability of Lender to Submit Forms.  If any Lender determines, as
a result of any change in applicable law, regulation or treaty, or in any
official application or interpretation 

                                     -28-
<PAGE>
 
thereof, that it is unable to submit to the Company or the Administrative Agent
any form or certificate that such Lender is obligated to submit pursuant to
subsection (b) of this Section 4.10 or that such Lender is required to withdraw
or cancel any such form or certificate previously submitted or any such form or
certificate otherwise becomes ineffective or inaccurate, such Lender shall
promptly notify the Company and Administrative Agent of such fact and the Lender
shall to that extent not be obligated to provide any such form or certificate
and will be entitled to withdraw or cancel any affected form or certificate, as
applicable.

          Section 4.11.  Increase in Commitments.  At any time prior to 30 days
after the close of the primary syndication as reasonably determined and
established by the Administrative Agent, in the event that sufficient
commitments are received from banks and other financial institutions (other than
Bank of Montreal and Bank of America National Trust and Savings Association
(herein, the "Initial Lenders")), such that the Initial Lenders' remaining
Commitments, after giving effect to the syndication of the credit facilities
provided for herein, are at their desired initial hold levels, and the aggregate
Commitments hereunder and commitments under the 364-Day Credit Agreement exceed
$250,000,000 (such excess being referred to herein as the "Overage"), then in
that event the Administrative Agent shall notify the Company of the Overage, and
the Company may request that the aggregate Commitments hereunder be increased by
the lesser of $30,000,000 and 60% of the Overage by offering such increase to
one or more banks or other financial institutions (each such bank or financial
institution being hereinafter referred to as an "Additional Lender") selected by
the Company and acceptable to the Lead Arrangers, Book Managers, and Syndication
Agents and the Administrative Agent.  Such increase in the Commitments shall
also be subject to the satisfaction of the following conditions: (a) each such
increase shall be at least $3,000,000 or such greater amount which is an
integral multiple $1,000,000; (b) the Administrative Agent shall have received
an acknowledgement agreement providing for such increase in form and substance
satisfactory to it executed by the Company, the Administrative Agent, and the
relevant Additional Lender; and (c) the Administrative Agent shall have received
a Note duly executed by the Company in favor of the relevant Additional Lender.
Upon the satisfaction of such conditions, effective as of the date set forth
above in such acknowledgement agreement, each such Additional Lender shall
thereafter be a "Lender" party to this Agreement and shall be entitled to all
rights, benefits and privileges afforded a Lender hereunder and subject to the
obligations of a Lender hereunder to the extent of its Commitment and Exhibit A
shall be deemed amended reflecting the increase in the aggregate Commitments
caused by the inclusion of the Commitment of the Additional Lender.
Concurrently with the effectiveness of such increase, each Additional Lender
shall fund its percentage of the outstanding Loans and overdue reimbursement
obligations with respect to Letters of Credit, if any, to the Administrative
Agent so that after giving effect thereto each Lender, including the Additional
Lender, holds a pro rata share (in accordance with its Commitment percentage) of
the outstanding Loans and credit risks with respect to Letters of Credit and the
Company shall pay to each Lender all amounts due under Section 3.6 hereof as a
result of any prepayment of any outstanding LIBOR Portions of the Loans.

          Section 4.12.  Extensions of Commitments.  Not less than 45 days nor
more than 60 days prior to each anniversary of the date hereof, the Company may
advise the Administrative Agent in writing of its desire to extend the
Termination Date for an additional 12 months and the Administrative Agent shall
promptly notify the Lenders of each such request; provided not more 

                                     -29-
<PAGE>
 
than one such request for the extension of the Termination Date may be made in
any one calendar year. The Lenders shall notify the Administrative Agent in
writing not later than 30 days before the anniversary date hereof following such
request whether such Lender agrees to the requested extension. No Lender shall
be under any obligation or commitment to extend such date and no such obligation
or commitment on the part of any Lender shall be inferred from the provisions of
this Section (it being understood that any Lender may accept or decline such a
request in its sole discretion and on such terms as such Lender may elect).
Failure on the part of any Lender to respond to such a request by the required
date set forth above shall be deemed to be a denial of such request by such
Lender. The requested extension shall not be granted unless Lenders holding
Commitments aggregating at least 80% of the aggregate Commitments in effect at
such time shall have consented in writing to such extension. If Lenders holding
100% of the aggregate Commitments consent to such extension, the Termination
Date will be automatically extended for an additional 12 months. If Lenders
holding Commitments aggregating less than 100%, but equal to or greater than
80%, of the aggregate Commitments consent to such extension, the Company may
elect by written notice to the Administrative Agent prior to the anniversary
date hereof following the original request to (i) rescind the original request,
in which case there shall be no extension of the Termination Date pursuant to
this Section, (ii) continue the credit facilities provided for herein for such
additional period with respect to the Commitments of the consenting Lenders,
with the Commitment of any Lender who has not consented to such extension
(herein a "Non-Consenting Lender") to be terminated on such anniversary date (at
which time all Obligations of such Non-Consenting Lender shall be paid and
satisfied in full by the Company) or (iii) require any such Non-Consenting
Lender to transfer and assign its Commitment and its other interests, rights,
and obligations under the Loan Documents to another bank or financial
institution willing to provide such extended financing in accordance with
Section 4.13 hereof. The Administrative Agent shall provide prompt notice to the
Company and the Lenders in writing as to whether the requested extension has
been granted and, if applicable, the list of Non-Consenting Lenders. In the
event the Administrative Agent requests, the Company and the Lenders shall
execute and deliver such documents as the Administrative Agent may deem
necessary or appropriate to relect any such extension, and all costs and
expenses incurred by the Administrative Agent in connection therewith shall be
paid by the Company.

     Section 4.13.  Substitution of Lenders. Upon the receipt by the Company of
(a) a claim from any Lender for compensation under Sections 2.3(d), 3.9, 4.9, or
4.10 hereof, (b) notice by any Lender to the Company of any illegality pursuant
to Section 3.7 hereof, or (c) notice from the Administrative Agent that a Lender
or Lenders have not approved an extension of the Termination Date pursuant to
Section 4.12 hereof (any such Lender referred to in clause (a), (b), or (c)
above being hereinafter referred to as an "Affected Lender"), the Company may
require, at its expense, any such Affected Lender to assign, at par plus accrued
interest and fees, without recourse, all of its interest, rights and obligations
hereunder (including all of its Commitment, Loans and credit risks with respect
to Letters of Credit and other amounts at any time owing to it hereunder and the
other Loan Documents) to a bank or financial institution specified by the
Company, provided that (i) such assignment shall not conflict with or violate
any law, rule, or regulation or order of any court or other governmental
authority, (ii) the Company shall have received the written consent of the
Administrative Agent, which consent shall not be unreasonably withheld, to such
assignment, (iii) the Company shall have paid to the Affected 

                                     -30-
<PAGE>
 
Lender all monies (together with amounts due such Affected Lender under Section
3.6 hereof as if the Loans owing it were prepaid rather than assigned), other
than such principal, interest and fees accrued and owing to it hereunder, and
(iv) the assignment is entered into in accordance with the other requirements of
Section 12.12 hereof.

SECTION 5.  GUARANTIES.

     Section 5.1.  Guaranty. Payment of the Obligations hereunder and under the
other Loan Documents shall at all times be jointly and severally guaranteed
pursuant to Section 11 hereof by MK-Ohio and Washington and from time to time
such other Restricted Subsidiaries (the "Necessary Parties") so that as of the
end of each fiscal quarter of the Company the assets of the Company, MK-Ohio,
Washington and the Necessary Parties are not less than 90% of the assets of the
Company and all of its Restricted Subsidiaries taken as a whole at such time.
The Company shall cause each Necessary Party to execute a supplement to the
guaranty provided in Section 11 hereof pursuant to which such Restricted
Subsidiary joins in and becomes obligated as a guarantor hereunder, which
supplement shall be in the form attached hereto as Exhibit C or in such other
form satisfactory to the Administrative Agent (MK-Ohio, Washington and the from
time to time Necessary Parties are herein collectively referred to as the
"Guarantors" and each individually as a "Guarantor"). The Company shall also
cause such Guarantor to execute and deliver, at the Company's cost and expense,
such other instruments, documents, certificates and opinions required by the
Administrative Agent in connection therewith.

SECTION 6.  REPRESENTATIONS AND WARRANTIES.

     The Company represents and warrants to the Lenders as follows:

     Section 6.1.  Organization and Power. The Company is duly organized and
existing under the laws of the state of its incorporation, and is duly licensed
or qualified to do business in each state where the nature of the assets owned
or leased by it or business conducted by it requires such licensing or
qualification and in which the failure to be so licensed or qualified would have
a Material Adverse Effect and has all necessary corporate power to carry on its
present business. The Company has full right, power and authority to enter into
this Agreement, to make the borrowings herein provided for, to issue the Notes
in evidence thereof, to execute and deliver the Applications and the other Loan
Documents executed and delivered or to be executed and delivered by it, and to
perform each and all of the matters and things herein and therein provided for.
Each Guarantor has full right, power and authority to enter into the Loan
Documents executed by it and to perform each and all of the matters and things
therein provided for. The Loan Documents do not, nor will the performance or
observance by the Company or any Subsidiary of any of the matters and things
herein or therein provided for, contravene any provision of law or any charter
or by-law provision of the Company or any such Subsidiary or constitutes a
breach or default under any covenant, indenture or agreement of or affecting the
Company or any such Subsidiary where such breach or default would have a
Material Adverse Effect.

                                     -31-
<PAGE>
 
     Section 6.2.  Subsidiaries. Each Subsidiary is duly organized and existing
under the laws of the jurisdiction of its incorporation or organization, and is
duly licensed or qualified to do business in each state or other jurisdiction
where the nature of the assets owned or leased by it or business conducted by it
requires such licensing or qualification and in which the failure to be so
licensed or qualified would have a Material Adverse Effect and has all necessary
power to carry on its present business. Schedule 6.2 hereto identifies each
Subsidiary, the jurisdiction of its incorporation or organization, the
percentage of issued and outstanding shares of each class of its capital stock
or other equity interests owned by the Company and the Subsidiaries and, if such
percentage is not 100% (excluding directors' qualifying shares as required by
law), a description of each class of its authorized capital stock or other
equity interests and the number of shares of each class issued and outstanding,
together with a designation of those Subsidiaries which are Restricted
Subsidiaries (including a designation of those which are Material Subsidiaries)
and those which are Unrestricted Subsidiaries. All of the outstanding shares of
capital stock or other equity interests of each Subsidiary are validly issued
and outstanding and fully paid and nonassessable, and all shares of each
Subsidiary indicated on Schedule 6.2 as owned by the Company or a Subsidiary are
owned, beneficially and of record, by the Company or such Subsidiary free and
clear of all liens, security interests, charges and encumbrances. There are no
outstanding commitments or other obligations of any Subsidiary to issue, and no
options, warrants or other rights of any Person to acquire, any shares of any
class of capital stock or other equity interests of any Subsidiary, except for
options granted in the ordinary course to officers and employees of non-Material
Subsidiaries or of Unrestricted Subsidiaries which, as to any Subsidiary, do
not, if exercised, aggregate 10% or more of the capital stock of any such
Subsidiary.

     Section 6.3.  Use of Proceeds; Regulation U. The Company shall use proceeds
of the Loans and other extensions of credit made available hereunder solely for
the purpose of refinancing existing debt of the Company and its Subsidiaries,
for the acquisition of the Acquired Assets, and for its working capital and
other general corporate purposes. Neither the Company nor any Subsidiary is
engaged in the business of extending credit for the purpose of purchasing or
carrying margin stocks (within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System), and no part of the proceeds of any
loan or extension of credit hereunder will be used to purchase or carry any
margin stock or extend credit to others for the purpose of purchasing or
carrying any margin stock if as a result thereof such loan or other extension of
credit would violate Regulation U or any interpretation thereof.

     Section 6.4.  Financial Statements. (a) The financial statements of the
Company and its Subsidiaries for the year ended November 30, 1998, including an
audited consolidated balance sheet as of November 30, 1998, and an audited
consolidated statement of profit and loss and statement of cash flows for the
twelve months ended said date, prepared by the Company, and heretofore furnished
to the Lenders, truly and accurately reflect the financial condition of the
Company and its Subsidiaries taken as a whole as at said date and the results of
operations and cash flows for the period covered thereby. Except as disclosed on
Schedule 6.4 hereof, the Company and its Subsidiaries have no contingent
liabilities which are material to them other than as indicated on said financial
statements and, since the date of such financial statements, there have been no
material adverse changes in the condition, financial or otherwise, business or
operations of the Company or its Subsidiaries taken as a whole.

                                     -32-
<PAGE>
 
     (b) The unaudited pro forma combined, condensed, and consolidated balance
sheet and combined, condensed, and consolidated statements of operations for the
Company and its Subsidiaries heretofore delivered to the Lenders fairly present
(subject to the qualifications and assumptions set forth in the notes attached
thereto) the combined financial condition of the Company and its Subsidiaries as
at the dates thereof and for the periods covered thereby.

     Section 6.5.  Litigation and Taxes. Except as disclosed on Schedule 6.4
hereof, there is no litigation or governmental proceeding pending, nor to the
knowledge of the Company threatened, against the Company or any Subsidiary which
could reasonably be expected to result in a Material Adverse Effect. The income
tax returns of the Company and its Subsidiaries for the taxable year ended
November 30, 1998 and for all taxable years ended prior to said date, have been
filed or extended with the appropriate governmental or taxing authorities, and
any additional assessments in connection with any such years have been paid or
the applicable statute of limitations therefor has expired. No objections to or
controversies in respect of the income tax returns of the Company or any
Subsidiary are pending or threatened which could reasonably be expected to
result in a Material Adverse Effect. No authorization, consent, license, or
exemption from, or filing or registration with, any court or governmental
department, agency or instrumentality, is or will be necessary to the valid
execution, delivery or performance by the Company or any Subsidiary of any Loan
Document to be executed and delivered by it.

     Section 6.6.  Burdensome Contracts with Affiliates. Neither the Company nor
any Subsidiary is a party to any material contracts or agreements with any of
its Affiliates on terms and conditions which are materially less favorable to
the Company or such Subsidiary than would be usual and customary in similar
contracts or agreements between Persons not affiliated with each other.

     Section 6.7.  ERISA. The Company and each Subsidiary are each in compliance
in all material respects with the Employee Retirement Income Security Act of
1974, as amended ("ERISA") to the extent applicable to it and has received no
notice to the contrary from the Pension Benefit Guaranty Corporation ("PBGC"),
and, in the event of the Company's or any Subsidiary's partial or complete
withdrawal from any pension plans or multiemployer pension plans subject to
Title IV of ERISA or termination of any other pension plans subject to Title IV
of ERISA, the liability of the Company and its Subsidiaries for any unfunded
vested benefits thereunder could not reasonably be expected to result in a
Material Adverse Effect.

     Section 6.8.  Full Disclosure. The statements and information furnished to
the Lenders in connection with the negotiation of this Agreement and the
commitments by the Lenders to provide all or part of the financing contemplated
hereby do not, taken as a whole, contain any untrue statement of a material fact
or omit a material fact necessary to make the material statements contained
therein or herein not misleading, except for such thereof as were corrected in
subsequent written statements furnished the Lenders (the Lenders acknowledging
that as to any projections furnished to the Lenders, the Company only represents
that the same were prepared on the basis of information and estimates it
believes to be reasonable). There is no fact peculiar to the Company or any
Subsidiary which the Company has not disclosed to the Lenders in writing which
materially adversely affects nor, so far as the Company now can reasonably
foresee, is reasonably likely to have a Material Adverse Effect.

                                     -33-
<PAGE>
 
     Section 6.9.  Compliance with Law. (a) Except as disclosed on Schedule 6.4
hereof, neither the Company nor any Subsidiary is (i) in default in any material
respect with respect to any order, writ, injunction or decree of any court or
(ii) in default in any material respect under any law, ordinance, order,
regulation, license or demand (including ERISA, the Occupational Safety and
Health Act of 1970 and laws and regulations establishing quality criteria and
standards for air, water, land and toxic waste) of any federal, state, municipal
or other governmental agency, default with respect to or under which is
reasonably likely to result in a Material Adverse Effect; and (b) the Company
and each Subsidiary are each in compliance with all applicable state and federal
environmental, health and safety statutes and regulations, including, without
limitation, regulations promulgated under the Resource Conservation and Recovery
Act of 1976, 42 U.S.C. (S)(S)6901 et seq., except where failure to be in
compliance is reasonably likely not to have a Material Adverse Effect, and, to
the Company's knowledge, neither the Company nor any Subsidiary will have
acquired, incurred or assumed, directly or indirectly, any contingent liability
in connection with the release of any toxic or hazardous waste or substance into
the environment which is reasonably likely to have a Material Adverse Effect.
Insofar as known to the responsible officers of the Company, neither the Company
nor any Subsidiary is liable, in whole or in part, for, nor are any of the
assets or property of the Company or any Subsidiary subject to a lien in favor
of any governmental entity for any material liability arising from or in any way
relating to, the costs of cleaning up, remediating or responding to a release of
hazardous substances (including, without limitation, petroleum, its by-products
or derivatives, or other hydrocarbons) except as specifically disclosed in the
10-K Statement of the Company dated November 30, 1998.

     Section 6.10.  Governmental Authority and Licensing. The Company and its
Subsidiaries have received all licenses, permits, and approvals of all Federal,
state, local, and foreign governmental authorities, if any, necessary to conduct
their business, in each case where the failure to obtain or maintain the same is
reasonably likely to have a Material Adverse Effect. No investigation or
proceeding which, if adversely determined, is reasonably likely to result in
revocation or denial of any material license, permit, or approval is pending or,
to the knowledge of the Company, threatened.

     Section 6.11.  Investment Company; Public Utility Holding Company. Neither
the Company nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended, or a "public utility holding company" within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

     Section 6.12.  Year 2000 Compliance. The information contained in this
Section 6.12 is a YEAR 2000 READINESS DISCLOSURE. The Company (a) is conducting
a comprehensive review and assessment of the computer applications of the
Company and its Subsidiaries and is making inquiries of its material suppliers,
service vendors (including data processors) and customers, with respect to any
defect in computer software, data bases, hardware, controls and peripherals
related to the occurrence of the year 2000 or the use at any time of any date
which is before, on and after December 31, 1999, in connection therewith, (b)
has developed a plan and timeline for addressing Year 2000 Problems on a timely
basis, and (c) is implementing the plan referred to in clause (b) above in
accordance with the timetable referred to therein. The completion of the

                                     -34-
<PAGE>
 
inventory phase of the plan has exceeded the original target timetable; however,
the Company believes that the project completion target date remains achievable.
Based upon the results of its comprehensive review and assessment to date, the
Company is not aware of any Year 2000 Problem that could reasonably be expected
to have a Material Adverse Effect.

     Section 6.13.  Purchase Agreement. The Company has entered into one or more
agreements and instruments (collectively, the "Purchase Agreement") relating to
its acquisition of the Acquired Assets from CBS Corporation and/or one of more
of its affiliates (herein, the "Seller"), which Purchase Agreement is on terms
and conditions substantially the same as disclosed to the Lenders in the
Company's January 1999 Rating Agency Presentation (the "Rating Agency
Presentation") or otherwise disclosed to the Lenders in writing on or prior to
the date hereof. The Purchase Agreement has not been amended or modified in any
material respect and no material condition to the effectiveness thereof or the
obligations of the Company or the Seller thereunder has been waived except to
the extent disclosed in writing to the Lenders on or prior to the date hereof.
The Company has all necessary right, power, and authority to consummate the
transactions contemplated by the Purchase Agreement and to perform all of its
obligations thereunder. The Purchase Agreement has been duly authorized,
executed, and delivered by the Company and constitutes the valid and binding
obligation of the Company enforceable against it in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency, fraudulent
conveyance or similar laws affecting creditors' rights generally and general
principles of equity (regardless of whether the application of such principles
is considered in a proceeding in equity or at law); and the Purchase Agreement
does not, nor does the observance or performance by the Company of any of the
matters and things therein provided for, (a) contravene or constitute a default
under any provision of law or any judgment, injunction, order, or decree binding
upon the Company or any provision of the articles of incorporation or by-laws of
the Company, (b) contravene or constitute a default under any covenant,
indenture, or agreement of or affecting the Company or any of its Property where
such contravention or default is reasonably likely to have a Material Adverse
Effect, (c) result in the creation or imposition of any lien, charge, or
encumbrance on any of the Company's Property. No authorization, consent,
license, or exemption from, or filing or registration with, any court or
governmental department, agency, or instrumentality, nor any approval or consent
of any other Person, is or will be necessary to the valid execution, delivery,
or performance by the Company of the Purchase Agreement or of any other
instrument or document executed and delivered in connection therewith, except
for such thereof that have heretofore been obtained and remain in full force and
effect and those the failure of which to obtain or make would not materially
impair the ability of the Company to perform its obligations under the Purchase
Agreement. The Company is not in default in any material respect of its
obligations under the Purchase Agreement. Upon the funding of the purchase price
under the Purchase Agreement, the Company shall have acquired the Acquired
Assets free and clear of all liens, charges and encumbrances. Neither the
Company nor any Subsidiary (including any GESCO Subsidiary) will incur or assume
any material direct or contingent liabilities in connection with the purchase of
the Acquired Assets (including, without limitation, any liabilities for
environmental clean up and liabilities for unfunded pension and welfare plan
obligations) except as disclosed in writing to the Lenders on or prior to the
date hereof.

                                     -35-
<PAGE>
 
     Section 6.14.  Hazardous Materials Risk Management. The Company and its
Subsidiaries manage the risks associated with handling Hazardous Materials in
the ordinary course and any Hazardous Materials Liability associated therewith
in a manner consistent with prudent business practices and similar to companies
similarly situated and operating like businesses, including, without limitation,
protecting the Company and its Subsidiaries from potential Hazardous Materials
Liability where reasonably possible and appropriate through contractual
indemnifications from governmental agencies and authorities (including, without
limitation, the United States Department of Energy) and other third parties,
maintaining hazardous liability insurance and, with respect to Hazardous
Materials Liability relating to radioactive or other nuclear materials,
statutory limitations of liabilities imposed under the Price-Anderson Act, as
amended.

contracts or agreements between Persons not affiliated with each other.

     Section 8.15.  No Change in Fiscal Year. The Company will not, nor will it
permit any Restricted Subsidiary to, change its fiscal year, provided that the

     Section 8.18.  Year 2000 Assessment. The information contained in this
Section 8.18 is a YEAR 2000 READINESS DISCLOSURE. The Company will take all
actions it deems necessary and commit resources it deems adequate to assure that
its electronic information and communication systems (and those of all
Subsidiaries) are able to effectively process dates, including dates before, on

internal or external audit reports otherwise prepared in the ordinary course of
business) reasonably acceptable to the Administrative Agent as to the capability
of the Company and its Subsidiaries to conduct its and their businesses and
operations before, on and after January 1, 2000, without experiencing a Year
2000 Problem causing a Material Adverse Effect. Without request, the Company
will provide the Administrative Agent and the Lenders a status report of its
current Year 2000 Problems and a summary of its implementation plan and timeline
therefor no later than June 30, 1999. The Company will promptly notify the
Administrative Agent and the Lenders in the event the Company discovers or
determines that any other Year 2000 Problem exists with respect to any computer

be expected to have a Material Adverse Effect.

                                     -48-
<PAGE>

The date hereof           November 30, 2000                3.5 to 1.0

fiscal quarter of the Company ending during the periods specified below, the

completed fiscal quarters of the Company, minus (ii) Capital Expenditures of the
Company and its Subsidiaries (excluding Capital Expenditures of the GESCO
Subsidiaries) during the same four fiscal quarters to (b) Fixed Charges for the
same four fiscal quarters then ended (the "Fixed Charge Coverage Ratio") to be
less than:

                                                           COVERAGE RATIO SHALL
FROM AND INCLUDING        TO AND INCLUDING                 NOT BE LESS THAN:    
                                                            
The date hereof           November 30, 1999                1.75 to 1.0
December 1, 1999          and at all times thereafter      2.00 to 1.0

; provided, however, for any fiscal quarter ending on or after December 1, 1999,
so long as the Company has a Moody's Rating of Baa3 or higher or an S&P Rating
of BBB- or higher, then the required Fixed Charge Coverage Ratio for the period
then ended shall be reduced to 1.75 to 1.0.

     Section 8.24.  Hazardous Materials Risk Management. The Company will, and
will cause each Subsidiary to, assess and manage on an on-going basis the risks
associated with the handling of Hazardous Materials in the ordinary course of

<PAGE>
 
shall, upon request of the Required Lenders), by notice to the Company, take any

          (a) terminate the obligation of the Lenders to extend any further

     Credit, with the funds so paid to, if the Company so requests, be invested

Lenders shall have the right to require the Company to specifically perform such
undertaking whether or not any draws have been made under the Letters of Credit,
and (d) the Administrative Agent may exercise all remedies available to it under
the Loan Documents or applicable law.

Section 10.  The Administrative Agent and Issuing Banks.

     Section 10.1. Appointment and Authorization. Each Lender hereby appoints
and authorizes the Administrative Agent to take such action as agent on its
behalf and to exercise 

                                     -52-
<PAGE>
 
such powers hereunder and under the Loan Documents as are designated to the
Administrative Agent by the terms hereof and thereof together with such powers
as are reasonably incidental thereto. The Lenders expressly agree that the
Administrative Agent is not acting as a fiduciary of the Lenders in respect of
the Loan Documents, the Company or otherwise, and nothing herein or in any of
the other Loan Documents shall result in any duties or obligations on the
Administrative Agent or any Lenders except as expressly set forth herein. The
Administrative Agent may resign at any time by sending 20 days prior written
notice to the Company and the Lenders and may be removed by the Required Lenders
upon 20 days prior written notice to the Company and the Lenders. In the event
of any such resignation or removal the Required Lenders may appoint a new agent,
which shall succeed to all the rights, powers and duties of the Administrative
Agent hereunder and under the Loan Documents, such new Administrative Agent to
be subject to the reasonable consent of the Company unless a Default or Event of
Default has occurred and is continuing. Any resigning or removed Administrative
Agent shall be entitled to the benefit of all the protective provisions hereof
with respect to its acts as an agent hereunder, but no successor Administrative
Agent shall in any event be liable or responsible for any actions of its
predecessor. If the Administrative Agent resigns or is removed and no successor
is appointed, the rights and obligations of such Administrative Agent shall be
automatically assumed by the Required Lenders and (i) the Company shall be
directed to make all payments due each Lender hereunder directly to such Lender
and (ii) the Administrative Agent's rights in the Loan Documents shall be
assigned without representation, recourse or warranty to the Lenders as their
interests may appear.

     Section 10.2. Rights as a Lender. The Administrative Agent has and reserves
all of the rights, powers and duties hereunder and under the other Loan
Documents as any Lender may have and may exercise the same as though it were not
the Administrative Agent and the terms "Lender" or "Lenders" as used herein and
in all of such documents shall, unless the context otherwise expressly
indicates, include the Administrative Agent in its individual capacity as a
Lender. The Administrative Agent reserves the right to engage in other business
transactions with the Company, the Subsidiaries and their Affiliates.

     Section 10.3. Standard of Care. The Lenders acknowledge that they have
received and approved copies of the Loan Documents, and such other information
and documents concerning the transactions contemplated and financed hereby as
they have requested to receive and/or review. The Administrative Agent makes no
representations or warranties of any kind or character to the Lenders with
respect to the validity, enforceability, genuineness, perfection, value, worth
or collectibility hereof or of the other Loan Documents or of the liens, if any,
provided for thereby or of any other documents called for hereby or thereby or
of the collateral, if any. The Administrative Agent need not verify the worth or
existence of any collateral, or any other Property, and may rely exclusively on
reports provided by the Company. The Lenders agree that neither the
Administrative Agent nor any director, officer employee, agent or representative
thereof (including any security trustee therefor) shall in any event be liable
for any clerical errors or errors in judgment, inadvertence or oversight, or for
action taken or omitted to be taken by it or them hereunder or under the Loan
Documents or in connection herewith or therewith except for its or their own
gross negligence or willful misconduct. The Administrative Agent shall incur no
liability under or in respect of this Agreement or the other Loan Documents by
acting upon any notice, certificate, warranty, instruction or statement (oral or
written) of 

                                     -53-
<PAGE>
 
anyone (including anyone in good faith believed by it to be authorized to act on
behalf of the Company), unless it has actual knowledge of the untruthfulness of
same. The Administrative Agent agrees to use the same care in protecting the
interests of the Lenders in the Loans and Letters of Credit as it uses for
similar loans or extensions of credit held by it solely for its own account. The
Administrative Agent shall be entitled to assume that no Default or Event of
Default exists, absent actual knowledge thereof, unless notified to the contrary
by a Lender. The Administrative Agent shall in all events be fully protected in
acting or failing to act in accord with the instructions of the Required
Lenders. Upon the occurrence of an Event of Default hereunder, the
Administrative Agent shall take such action with respect to the enforcement of
its rights and remedies hereunder and under any collateral and the preservation
and protection thereof as it shall be directed to take by the Required Lenders
(and shall consult with the Lenders as to actions to be taken) but unless and
until the Required Lenders have given such direction the Administrative Agent
shall take or refrain from taking such actions as it deems appropriate and in
the best of interest of all Lenders. The Administrative Agent shall in all cases
be fully justified in failing or refusing to act hereunder unless it shall be
indemnified to its reasonable satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Administrative Agent may treat the owner
of any Note as the holder thereof until written notice of transfer shall have
been filed with it as provided in Section 12.12 hereof signed by such owner in
form satisfactory to the Administrative Agent. Each Lender acknowledges that it
has independently and without reliance on the Administrative Agent or any other
Lender and based upon such information, investigations and inquiries as it deems
appropriate made its own credit analysis and decision to extend credit to the
Company. It shall be the responsibility of each Lender to keep itself informed
as to the creditworthiness of the Company and each Subsidiary and the
Administrative Agent shall have no liability to any Lender with respect thereto.

     Section 10.4. Costs and Expenses. Each Lender agrees to reimburse the
Administrative Agent for all out-of-pocket costs and expenses suffered or
incurred by the Administrative Agent or any security trustee in performing its
duties hereunder and under the other Loan Documents or in the exercise of any
right or power imposed or conferred upon the Administrative Agent hereby or
thereby, to the extent that the Administrative Agent is not promptly reimbursed
for same by the Company or out of any collateral, all such costs and expenses to
be borne by the Lenders ratably in accordance with the amounts of their
respective Commitments.

     Section 10.5. Indemnity. The Lenders shall ratably indemnify and hold the
Administrative Agent, and each of its directors, officers, employees, agents or
representatives (including as such any security trustee therefor), harmless from
and against any liabilities, losses, costs or expenses suffered or incurred by
them under this Agreement or any of the other Loan Documents or in connection
with the transactions contemplated hereby or thereby, regardless of when
asserted or arising, except to the extent they are promptly reimbursed for the
same by the Company or out of any collateral and except to the extent that any
event giving rise to a claim was caused by the gross negligence or willful
misconduct of the party seeking to be indemnified.

     Section 10.6. Issuing Bank. The Issuing Bank shall act on behalf of the
Lenders with respect to any Letters of Credit issued by it and the documents
associated therewith. The Issuing Bank shall have all of the benefits and
immunities (i) provided to the Administrative Agent in 

                                     -54-
<PAGE>
 
this Section 10 with respect to any acts taken or omissions suffered by the
Issuing Bank in connection with Letters of Credit issued by it or proposed to be
issued by it and the Applications pertaining to such Letters of Credit as fully
as if the term "Administrative Agent", as used in this Section 10, included
Issuing Bank with respect to such acts or omissions and (ii) as additionally
provided in this Agreement with respect to such Issuing Bank.

     Section 10.7. Designation of Additional Agent. The Administrative Agent
shall have the continuing right, for purposes hereof, at any time or from time
to time to designate one or more Lenders (and/or its or their Affiliates) as
"Documentation Agents," "Lead Arrangers, Book Managers, and Syndication Agents,"
"Arrangers" or otherwise for purposes hereto, but such designations shall have
no substantive effect, and such Lenders and their Affiliates shall have no
additional powers, duties, or responsibilities as a result thereof.

Section 11.  Guaranty.

     Section 11.1. The Guaranty. To induce the Lenders to provide the credits
described herein and in consideration of benefits expected to accrue to the
Company by reason of the Commitments and for other good and valuable
consideration, receipt of which is hereby acknowledged, each Guarantor hereby
unconditionally and irrevocably guarantees jointly and severally to the
Administrative Agent, the Lenders, and each other holder of any of the Notes,
the due and punctual payment of all present and future indebtedness of the
Company evidenced by or arising out of the Loan Documents, including, but not
limited to, the due and punctual payment of principal of and interest on the
Notes, obligations related to the Applications, and the due and punctual payment
of all other Obligations now or hereafter owed by the Company under the Loan
Documents as and when the same shall become due and payable, whether at stated
maturity, by acceleration or otherwise, according to the terms hereof and
thereof (the "Guaranteed Obligations"). In case of failure by the Company
punctually to pay any indebtedness or other obligations guaranteed hereby (after
giving effect to any applicable cure periods), each Guarantor hereby
unconditionally agrees jointly and severally to make such payment or to cause
such payment to be made punctually as and when the same shall become due and
payable, whether at stated maturity, by acceleration or otherwise, and as if
such payment were made by the Company.

     Section 11.2. Guarantee Unconditional. The obligations of each Guarantor as
a guarantor under this Section 11 shall be unconditional and absolute and,
without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by:

          (a) any extension, renewal, settlement, compromise, waiver or release
     in respect of any obligation of the Company or of any other guarantor under
     this Agreement or any other Loan Document or by operation of law or
     otherwise;

          (b) any modification or amendment of or supplement to this Agreement
     or any other Loan Document;

          (c) any change in the existence, structure or ownership of, or any
     insolvency, bankruptcy, reorganization or other similar proceeding
     affecting, the Company, any other 

                                     -55-

     guarantor, or any of their respective assets, or any resulting release or
     discharge of any obligation of the Company or of any other guarantor
     contained in any Loan Document;

          (d) the existence of any claim, set-off or other rights which the
     Company or any other guarantor may have at any time against the
     Administrative Agent, any Lender or any other Person, whether or not
     arising in connection herewith;

          (e) any failure to assert, or any assertion of, any claim or demand or
     any exercise of, or failure to exercise, any rights or remedies against the
     Company, any other guarantor or any other Person or Property;

          (f) any application of any sums by whomsoever paid or howsoever
     realized to any obligation of the Company, regardless of what obligations
     of the Company remain unpaid;

          (g) any invalidity or unenforceability relating to or against the
     Company or any other guarantor for any reason of this Agreement or of any
     other Loan Document or any provision of applicable law or regulation
     purporting to prohibit the payment by the Company or any other guarantor of
     the principal of or interest on any Note or any other amount payable under
     the Loan Documents; or

          (h) any other act or omission to act or delay of any kind by the
     Administrative Agent, any Lender or any other Person or any other
     circumstance whatsoever that might, but for the provisions of this
     paragraph, constitute a legal or equitable discharge of the obligations of
     any Guarantor under this Section 11.

     Section 11.3. Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances. Each Guarantor's obligations under this Section 11 shall remain
in full force and effect until the Commitments are terminated, all Letters of
Credit have expired, and the principal of and interest on the Notes and all
other amounts payable by the Company under this Agreement and all other Loan
Documents shall have been paid in full. If at any time any payment of the
principal of or interest on any Note or any other amount payable by the Company
under the Loan Documents is rescinded or must be otherwise restored or returned
upon the insolvency, bankruptcy or reorganization of the Company or of any
guarantor, or otherwise, each Guarantor's obligations under this Section 11 with
respect to such payment shall be reinstated at such time as though such payment
had become due but had not been made at such time.

     Section 11.4. Subrogation. Each Guarantor agrees it will not exercise any
rights which it may acquire by way of subrogation by any payment made hereunder,
or otherwise, until all the Guaranteed Obligations shall have been paid in full
subsequent to the termination of all the Commitments and expiration or
defeasance in full of all Letters of Credit. If any amount shall be paid to a
Guarantor on account of such subrogation rights at any time prior to the later
of (x) the payment in full of the Guaranteed Obligations and all other amounts
payable by the Company hereunder and the other Loan Documents and (y) the
termination of the Commitments and expiration of all Letters of Credit, such
amount shall be held in trust for the benefit of the Administrative Agent and
the Lenders and shall forthwith be paid to the Administrative Agent 

                                     -56-
<PAGE>
 
for the benefit of the Lenders or be credited and applied upon the Guaranteed
Obligations, whether matured or unmatured, in accordance with the terms of this
Agreement.

     Section 11.5. Waivers. Each Guarantor irrevocably waives acceptance hereof,
presentment, demand, protest and any notice not provided for herein, as well as
any requirement that at any time any action be taken by the Administrative
Agent, any Lender or any other Person against the Company, another guarantor or
any other Person.

     Section 11.6. Limit on Recovery. Notwithstanding any other provision
hereof, the right of recovery against any Guarantor under this Section 11 shall
not exceed $1.00 less than the lowest amount which would render such Guarantor's
obligations under this Section 11 void or voidable under applicable law,
including without limitation fraudulent conveyance law.

     Section 11.7. Stay of Acceleration. If acceleration of the time for payment
of any amount payable by the Company under this Agreement or any other Loan
Document is stayed upon the insolvency, bankruptcy or reorganization of the
Company, all such amounts otherwise subject to acceleration under the terms of
this Agreement or the other Loan Documents shall nonetheless be payable jointly
and severally by the Guarantors hereunder forthwith on demand by the
Administrative Agent made at the request of the Required Lenders.

Section 12.  Miscellaneous.

     Section 12.1. Waiver of Rights. No delay or failure on the part of any
Lender or the holder or holders of any Note in the exercise of any power or
right shall operate as a waiver thereof or as an acquiescence in any default,
nor shall any single or partial exercise thereof or the exercise of any other
power or right preclude any other right or the further exercise of any other
rights. The rights and remedies hereunder of the Company, the Administrative
Agent, the Lenders and of the holder or holders of any Note are cumulative to,
and not exclusive of, any rights or remedies which any of them would otherwise
have.

     Section 12.2. Non-Business Day. If any payment of principal shall fall due
on a day which is not a Business Day, interest at the rate such principal bears
for the period prior to maturity shall continue to accrue on such principal from
the stated due date thereof to and including the next succeeding Business Day on
which the same is payable.

     Section 12.3. Documentary Taxes. The Company agrees to pay any documentary,
stamp or similar taxes payable in respect to this Agreement or any other Loan
Document, including interest and penalties, in the event any such taxes are
assessed irrespective of when such assessment is made and whether or not any
credit is then in use or available hereunder.

     Section 12.4. Survival of Representations.  All representations and
warranties made in the Loan Documents or pursuant thereto or in certificates
given pursuant hereto or thereto shall survive the execution and delivery of
this Agreement and of the other Loan Documents, and shall continue in full force
and effect with respect to the date as of which they were made as long as any
credit is in use or available hereunder.

                                     -57-
<PAGE>
 
     Section 12.5. Set-off Sharing. Each Lender agrees with each other Lender a
party hereto that in the event such Lender shall receive and retain any payment,
whether by set-off or application of deposit balances or otherwise, on or in
respect of any Note or other Obligation outstanding under this Agreement in
excess of its ratable share of payments on all Notes and other Obligations then
outstanding to the Lenders, then such Lender shall purchase for cash at face
value, but without recourse, ratably from each of the other Lenders such amount
of the Notes or other Obligations held by each such other Lender (or interest
therein) as shall be necessary to cause such Lender to share such excess payment
ratably with all the other Lenders; provided, however, that if any such purchase
is made by any Lender, and if such excess payment or part thereof is thereafter
recovered from such purchasing Lender, the related purchases from the other
Lenders shall be rescinded ratably and the purchase price restored as to the
portion of such excess payment so recovered, but without interest.

     Section 12.6. Notices. Except as otherwise specified herein, all notices
hereunder and under the other Loan Documents shall be in writing (including,
without limitation, notice by telecopy) and shall be given to the relevant party
at its address or telecopier number set forth below, or such other address or
telecopier number as such party may hereafter specify by notice to the
Administrative Agent and the Company given by courier, by United States
certified or registered mail, by telecopy or by other telecommunication device
capable of creating a written record of such notice and its receipt. Notices
under the Loan Documents to the Lenders and the Administrative Agent shall be
addressed to their respective addresses or telecopier numbers set forth on the
signature pages hereof, and to the Company to:

               Morrison Knudsen Corporation
               720 Park Boulevard
               Boise, Idaho  83712
               Attention:  Vice President and Treasurer
               Telephone:  (208) 386-5887
               Telecopy:  (208) 386-0220

Each such notice, request or other communication shall be effective (i) if given
by telecopier, when such telecopy is transmitted to the telecopier number
specified in this Section or on the signature pages hereof and a confirmation of
such telecopy has been received by the sender, (ii) if given by mail, 5 days
after such communication is deposited in the mail, certified or registered with
return receipt requested, addressed as aforesaid or (iii) if given by any other
means, when delivered at the addresses specified in this Section or on the
signature pages hereof; provided that any notice given pursuant to Sections 2
and 3 hereof shall be effective only upon receipt.

     Section 12.7. Counterparts. This Agreement may be executed in any number of
counterparts, and by the different parties on different counterparts, each of
which when executed shall be deemed an original, but all such counterparts taken
together shall constitute one and the same instrument.

     Section 12.8. Successors and Assigns. This Agreement shall be binding upon
the Company and its successors and assigns, and shall be binding upon and inure
to the benefit of the 

                                     -58-
<PAGE>
 
Administrative Agent, the Lead Arrangers, Book Managers, and Syndication Agents,
the Documentation Agent and the Lenders and their respective successors and
assigns permitted pursuant to Section 12.12 hereof, including any subsequent
holder of any Note. The Company may not assign its rights or obligations
hereunder without the prior written consent of the Lenders.

     Section 12.9. Participants. Each Lender shall have the right at its own
cost to grant participations (to be evidenced by one or more agreements or
certificates of participation) in the Loans made by such Lender and credit risks
in Letters of Credit held by such Lender at any time and from time to time to
one or more other financial institutions, provided that no such participant
shall have any rights under this Agreement or any other Loan Document (the
participant's rights against the Lender granting its participation to be those
set forth in the participation agreement between the participant and such
Lender); provided, further, that no Lender shall transfer or grant any
participation under which the participant shall have rights to approve any
amendment to or waiver of this Agreement or any other loan Document except to
the extent such amendment or waiver would extend the final scheduled maturity of
any Loan, Note or Letter of Credit (unless such Letter of Credit is not extended
beyond the Termination Date) in which such participant is participating, or
reduce the rate or extend the time of payment of interest or fees thereon
(except in connection with a waiver of applicability of any post-default
increase in interest rates) or reduce the principal amount thereof, or increase
the amount of the participant's participation over the amount thereof then in
effect (it being understood that a waiver of any Default or Event of Default or
of a mandatory reduction in the Commitment or of a mandatory prepayment shall
not constitute a change in the terms of such participation, and that an increase
in any Commitment or Loan shall be permitted without the consent of any
participant if the participant's participation is not increased as a result
thereof. Each such Lender selling a participation shall be entitled to the
benefits of Sections 2.3(d), 3 and 4.9 hereof to the extent such Lender would
have been so entitled had no such participation been sold.

     Section 12.10. Costs and Expenses. The Company agrees to pay within 10 days
of demand all reasonable costs and expenses of the Administrative Agent, Lead
Arrangers, Book Managers, and Syndication Agents and Documentation Agent in
connection with the preparation, negotiation, syndication, and administration of
the Loan Documents, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent, in connection with the
preparation and execution of the Loan Documents, and any amendment, waiver or
consent related thereto, whether or not the transactions contemplated herein are
consummated. The Company further agrees to indemnify the Administrative Agent,
Lead Arrangers, Book Managers, and Syndication Agents, Documentation Agent, each
Lender, and their respective directors, officers and employees, against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all reasonable expenses of litigation or
preparation therefor, whether or not the indemnified Person is a party thereto,
or any settlement arrangement arising from or relating to any such litigation)
which any of them may pay or incur arising out of or relating to any Loan
Document or any of the transactions contemplated thereby or the direct or
indirect application or proposed application of the proceeds of any Loan or
Letter of Credit, other than those which arise from the gross negligence or
willful misconduct of the party claiming indemnification. The Company, upon
demand by the Administrative Agent, Lead Arrangers, Book Managers, and
Syndication Agents, Documentation 

                                     -59-
<PAGE>
 
Agent or a Lender at any time, shall reimburse the Agent, Lead Arrangers, Book
Managers, and Syndication Agents, Documentation Agent or such Lender for any
legal or other expenses incurred in connection with investigating or defending
against any of the foregoing (including any settlement costs relating to the
foregoing) except if the same is directly due to the gross negligence or willful
misconduct of the party to be indemnified. The obligations of the Company under
this Section shall survive the termination of this Agreement.

     Section 12.11. Construction. The parties hereto acknowledge and agree that
this Agreement shall not be construed more favorably in favor of one than the
other based upon which party drafted the same, it being acknowledged that all
parties hereto contributed substantially to the negotiation of this Agreement.

     Section 12.12. Assignments. (a) Each Lender may, from time to time, with
the consent of the Administrative Agent and the Documentation Agent and, so long
as no Event of Default exists, the Company, which consent will not be
unreasonably withheld, assign to other financial institutions part of the
indebtedness evidenced by the Notes and credit risks with respect to Letters of
Credit then owned by it together with an equivalent proportion of its obligation
to make Loans and participate in Letters of Credit hereunder pursuant to written
agreements executed by the assignor, the assignees, the Administrative Agent,
the Documentation Agent and, so long as no Event of Default exists, the Company,
which agreements shall specify in each instance the portion of the indebtedness
evidenced by the Notes and Applications which is to be assigned to each such
assignee and the portion of the Commitment of the assignor to be assumed by it
and shall be substantially in the form attached hereto as Exhibit D (the
"Assignment Agreements"); provided, however, that (i) each such assignment shall
be of a constant, and not a varying, percentage of the assigning Lender's rights
and obligations under this Agreement and the assignment shall cover the same
percentage of such Lender's Commitment, Loans, Note, and credit risk with
respect to Letters of Credit; (ii) unless the Administrative Agent, the
Documentation Agent and the Company otherwise consent, the aggregate amount of
the Commitment, Loans, Note, and credit risk with respect to Letters of Credit
of the assigning Lender being assigned pursuant to each such Assignment
Agreement (determined as of the effective date of the relevant Assignment
Agreement) shall in no event be less than $3,000,000 and, unless the assigning
Lender shall have assigned all of its Commitment, Loans, Note, and credit risk
with respect to Letters of Credit, the aggregate amount of the Commitment,
Loans, Note and credit risk with respect to Letters of Credit retained by the
assigning Lender shall in no event be less than $3,000,000; and (iii) the
assigning Lender must pay to the Administrative Agent a processing and
recordation fee of $3,500 and any out-of-pocket attorney's fees and expenses
incurred by the Administrative Agent in connection with each such Assignment
Agreement. Upon the execution of each Assignment Agreement by the assignor, the
assignee, the Administrative Agent, the Documentation Agent and, if applicable,
the Company (i) such assignee shall thereupon become a "Lender" for all purposes
of this Agreement with a Commitment in the amount set forth in such Assignment
Agreement (and Exhibit A hereto shall be deemed amended to reflect the aggregate
Commitments of the Lenders after giving effect thereto) and with all the rights,
powers and obligations afforded a Lender hereunder, provided that the assigning
Lender shall retain the benefit of all indemnities of the Company with respect
to matters arising prior to the effective date of such Assignment Agreement,
which shall survive and inure to the benefit of the assigning Lender, (ii) such
assigning Lender shall have no further 

                                     -60-
<PAGE>
 
liability for funding the portion of its Commitment assumed by such other Lender
and (iii) the address for notices to such Lender shall be as specified in the
Assignment Agreement executed by it. Concurrently with the execution and
delivery of such Assignment Agreement by the assignor, the assignee, the
Administrative Agent, the Documentation Agent and, if applicable, the Company
shall execute and deliver a Note to the assignee Lender in the amount of its
Commitment and a new Note to such assigning Lender in the amount of its
Commitment after giving effect to the reduction occasioned by such assignment,
all such notes to constitute "Notes" for all purposes of this Agreement.

     (b) Any Lender may at any time pledge or grant a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any such pledge or grant to a Federal Reserve Bank, and this
Section shall not apply to any such pledge or grant of a security interest;
provided that no such pledge or grant of a security interest shall release a
Lender from any of its obligations hereunder or substitute any such pledgee or
secured party for such Lender as a party hereto; provided further, however, the
right of any such pledgee or grantee (other than any Federal Reserve Bank) to
further transfer all or any portion of the rights pledged or granted to it,
whether by means of foreclosure or otherwise, shall be at all times subject to
the terms of this Agreement.

     Section 12.13. Amendments. Any provision of this Agreement or the other
Loan Documents may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by (a) the Company, (b) the Required Lenders,
and (c) if the rights or duties of the Administration Agent or an Issuing Bank
are affected thereby, the Administration Agent or such Issuing Bank, as
applicable; provided that:

          (i)  no amendment or waiver pursuant to this Section 12.13 shall (A)
     increase any Commitment of any Lender without the consent of such Lender or
     (B) reduce the amount of or postpone the date for any scheduled payment of
     any principal of or interest on any Loan or of any reimbursement obligation
     with respect to the Letter of Credit or of any fee payable hereunder
     without the consent of the Lender to which such payment is owing or which
     has committed to make such Loan or Letter of Credit (or participate
     therein) hereunder; and

          (ii) no amendment or waiver pursuant to this Section 12.13 shall,
     unless signed by each Lender, increase the aggregate Commitments hereunder
     (exclusive of increases permitted by Section 4.11 hereof), change the
     definitions of Termination Date or Required Lenders, change the provisions
     of this Section 12.13, Section 7, or Section 9, release any Guarantor, or
     affect the number of Lenders required to take any action hereunder or under
     any other Loan Document;

it being understood that waivers or modifications of covenants, Defaults or
Events of Default (other than those set forth in Section 9.1(j) and (k) hereof)
or of a mandatory reduction in the Commitments or of a mandatory prepayment may
be made at the discretion of the Required Lenders and shall not constitute an
increase of the Commitment of any Lender, and that any resulting increase in the
available portion of any Commitment of any Lender shall not constitute 

                                     -61-
<PAGE>
 
an increase in the Commitment of such Lender, and any waiver of applicability of
any post-default increase in interest rates may be made at the discretion of the
Required Lenders.

     Section 12.14. Entire Agreement. This Agreement and the Loan Documents
constitute the entire understanding of the parties with respect to the subject
matter hereof and any prior agreements, whether written or oral, with respect
thereto are superseded hereby.

     Section 12.15. Headings. Section headings used in this Agreement are for
reference only and shall not affect the construction of this Agreement.

     Section 12.16. Confidentiality. (a) Any information disclosed by the
Company or any of its Subsidiaries to the Administrative Agent or any of the
Lenders shall be used solely for purposes of this Agreement and for the purpose
of determining whether or not to extend other credit or financial accommodations
to the Company or its Subsidiaries and, if such information is not otherwise in
the public domain, shall not be disclosed by the Administrative Agent or such
Lender to any other Person except (i) to its independent accountants and legal
counsel (it being understood that the Persons to whom such disclosure is made
will be informed of the confidential nature of such information and instructed
to keep such information confidential), (ii) pursuant to statutory and
regulatory requirements, (iii) pursuant to any mandatory court order, subpoena
or other legal process, (iv) to the Administrative Agent or any other Lender,
(v) pursuant to any agreement heretofore or hereafter made between such Lender
and the Company which permits such disclosure, (vi) in connection with the
exercise of any right or remedy under the Loan Documents, provided that such
Lender or the Administrative Agent, as applicable, shall give the Company prior
written notice of any such disclosure or (vii) subject to an agreement
containing provisions substantially the same as those of this Section, to any
participant in or assignee of, or prospective participant in or assignee of, any
obligation or Commitment.

          (b) The Administrative Agent and the Lenders acknowledge that the
Company and its Subsidiaries perform classified contracts funded by and/or for
the benefit of the United States Government and, accordingly, neither the
Company nor any Subsidiary will be obligated to release, disclose or otherwise
make available to the Administrative Agent or any Lender any classified or
special nuclear material to any parties not in possession of a valid security
clearance and authorized by the appropriate agency of the United States
Government to receive such material.  The Administrative Agent and the Lenders
agree that in connection with any exercise of a right or remedy the United
States Government may remove classified information or government-issued
property prior to any remedial action implicating such classified information or
government-issued property.  Upon notice from the Company, the Administrative
Agent and the Lenders shall take such steps in accordance with this Agreement as
may be reasonably requested by the Company to enable the Company or any
Subsidiary to comply with the Foreign Ownership Control or Influence
requirements of the United States Government imposed from time to time.

     Section 12.17. Currency. Each reference in this Agreement to U.S. Dollars
or to an Available Foreign Currency (the "relevant currency") is of the essence.
To the fullest extent permitted by law, the obligation of the Company in respect
of any amount due in the relevant currency under this Agreement shall,
notwithstanding any payment in any other currency 

                                     -62-
<PAGE>
 
(whether pursuant to a judgment or otherwise), be discharged only to the extent
of the amount in the relevant currency that the Administrative Agent or Lender
entitled to receive such payment may, in accordance with normal banking
procedures, purchase with the sum paid in such other currency (after any premium
and costs of exchange) on the Business Day immediately following the day on
which such party receives such payment. If the amount in the relevant currency
so purchased for any reason falls short of the amount originally due in the
relevant currency, the Company shall pay such additional amounts, in the
relevant currency, as may be necessary to compensate for the shortfall. Any
obligations of the Company not discharged by such payment shall, to the fullest
extent permitted by applicable law, be due as a separate and independent
obligation and, until discharged as provided herein, shall continue in full
force and effect.

     Section 12.18. Excess Interest. Notwithstanding any provision to the
contrary contained herein or in any other Loan Document, no such provision shall
require the payment or permit the collection of any amount in excess of the
maximum amount of interest permitted by applicable law to be charged for the use
or detention, or the forbearance in the collection, of all or any portion of the
Loans or other Obligations outstanding under this Agreement or any other Loan
Document ("Excess Interest"). If any Excess Interest is provided for, or is
adjudicated to be provided for, herein or in any other Loan Document, then in
such event (a) the provisions of this Section shall govern and control; (b)
neither the Company nor any guarantor or endorser shall be obligated to pay any
Excess Interest; (c) any Excess Interest that the Administrative Agent or any
Lender may have received hereunder shall, at the option of the Administrative
Agent, be (i) applied as a credit against the then outstanding principal amount
of Loans hereunder, accrued and unpaid interest thereon (not to exceed the
maximum amount permitted by applicable law) and any other Obligations, or all of
the foregoing; (ii) refunded to the Company, or (iii) any combination of the
foregoing; (d) the interest rate payable hereunder or under any other Loan
Document shall be automatically subject to reduction to the maximum lawful
contract rate allowed under applicable usury laws, and this Agreement and the
other Loan Documents shall be deemed to have been, and shall be, reformed and
modified to reflect such reduction in the relevant interest rate; and (e)
neither the Company nor any guarantor or endorser shall have any action against
the Administrative Agent or any Lender for any damages whatsoever arising out of
the payment or collection of any Excess Interest.

     Section 12.19. Lender's Obligations Several. The obligations of the Lenders
hereunder are several and not joint. Nothing contained in this Agreement and no
action taken by the Lenders pursuant hereto shall be deemed to constitute the
Lenders a partnership, association, joint venture or other entity.

     Section 12.20. Governing Law. This Agreement and the Notes, and the rights
and duties of the parties hereto, shall be construed and determined in
accordance with the laws of the State of Illinois, without regard to principles
of conflicts of laws.

     Section 12.21. Submission to Jurisdiction; Waiver of Jury Trial. The
Company and each Guarantor hereby submits to the nonexclusive jurisdiction of
the United States District Court for the Northern District of Illinois and of
any Illinois State court sitting in the City of Chicago for purposes of all
legal proceedings arising out of or relating to this Agreement, the other Loan
Documents or the transactions contemplated hereby or thereby. The Company and
each 

                                     -63-
<PAGE>
 
Guarantor irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding
brought in such a court has been brought in an inconvenient forum. The Company,
the Guarantors, the Administration Agent, the Lead Arrangers, Book Managers, and
Syndication Agents, the Documentation Agent and each Lender hereby irrevocably
waive any and all right to trial by jury in any legal proceeding arising out of
or relating to any Loan Document or the transactions contemplated thereby.

Section 2.  The Revolving Credit.

     Section 2.1.   General Terms. Subject to all of the terms and conditions
hereof, the Lenders agree to extend a Revolving Credit to the Company which may
be availed of by the Company from time to time, be repaid and used again, during
the period from the date hereof to and including the Termination Date. The
Revolving Credit may be utilized by the Company in the form of Loans, all as
more fully hereinafter set forth, provided that the aggregate amount of Loans
outstanding at any one time shall not exceed the Commitments. The maximum amount
of the Revolving Credit which each Lender agrees to extend hereunder shall be as
set forth opposite its name on Exhibit A attached hereto and made a part hereof
(as the same shall be deemed amended after giving effect to the Assignment
Agreements referred to in Section 12.12 hereof). The obligations of the Lenders
hereunder are several and not joint and no Lender shall under any circumstance
be obligated to extend credit under the Revolving Credit in excess of its
Commitment or its pro rata share of the credit outstanding hereunder.

     Section 2.2.   The Loans. Subject to all of the terms and conditions
hereof, the Revolving Credit may be availed of by the Company in the form of
loans (individually a "Loan" and collectively the "Loans"). Each Borrowing shall
be in a minimum amount of $1,000,000 and thereafter in integral multiples of
$100,000 (with LIBOR Portions being in a minimum amount of $5,000,000 and
thereafter in integral multiples of $500,000) and shall be made pro rata from
the Lenders in accordance with the amounts of their Commitments. All Loans made
by each Lender shall be made against and evidenced by a promissory note
(individually a "Note" and collectively the "Notes") in the form (with
appropriate insertions) annexed hereto as Exhibit B. Each Note shall be in the
amount of the Commitment of the Lender to which it is payable and shall mature
on the Termination Date.

     Section 2.3.   Term Conversion Option. Subject to the terms and conditions
hereof, so long as no Default or Event of Default then exists, the Company shall
have the option on the Termination Date to maintain all or any part of the Loans
then outstanding on a non-revolving basis through the Term Credit Final Maturity
Date. The Company shall give the Administrative Agent not less than 5 Business
Days prior written notice of its election to exercise the Term Credit option
provided for herein, and the Administrative Agent shall thereafter promptly
notify the Lenders of such election. If the Company fails to give such notice,
or if a Default or Event of Default then exists, the Term Credit option shall be
unavailable to the Company and all Obligations shall be due and payable in full
on the Termination Date. If the Term Credit option is elected, and the
conditions thereto satisfied, no new Loans shall be made after the Termination
Date (at which time the Commitments of the Lenders to make new Loans shall
expire) and the Loans then outstanding shall remain outstanding and evidenced by
the Note through the Term Credit Final Maturity Date, at which time all
Obligations shall be due and payable in full

     Section 2.4.   Manner of Borrowing. The Company shall give written or
telephonic notice to the Administrative Agent (which notice shall be irrevocable
once given and, if given by telephone, shall be promptly confirmed in writing)
by no later than 12:00 noon (Chicago time) on the date the Company requests that
any Borrowing of Loans be made to it under the Commitments, and the
Administrative Agent shall promptly notify each Lender of the Administrative
Agent's receipt of each such notice. Each such notice shall specify the date of
the

                                     -13-
<PAGE>
 
Borrowing of Loans requested (which must be a Business Day, and which date shall
be at least three (3) Business Days subsequent to the date of such notice in the
case of any Borrowing of Loans constituting a LIBOR Portion) and the amount of
such Borrowing. Each Borrowing of Loans shall initially constitute part of the
applicable Base Rate Portion except to the extent the Company has otherwise
timely elected that such Borrowing constitute part of a LIBOR Portion as
provided in Section 3 hereof. The Company agrees that the Administrative Agent
may rely upon any written or telephonic notice given by any person the
Administrative Agent in good faith believes is an Authorized Representative
without the necessity of independent investigation and, in the event any
telephonic notice conflicts with the written confirmation, such telephonic
notice shall govern if the Administrative Agent and the Lenders have acted in
reliance thereon. The Lenders undertake to endeavor in good faith to honor on a
same day basis Borrowing requests received later than 12:00 noon (Chicago time)
but shall incur no liability to the Company if it is not reasonably practical
for them to honor such requests on a same day basis. Not later than 1:00 p.m.
(Chicago time) on the date specified for any Borrowing of Loans to be made
hereunder, each Lender shall make the proceeds of its Loan comprising part of
such Borrowing available to the Administrative Agent in Chicago, Illinois in
immediately available funds. Subject to the provisions of Section 7 hereof, the
proceeds of each Loan shall be made available to the Company at the principal
office of the Administrative Agent in Chicago, Illinois, in immediately
available funds, upon receipt by the Administrative Agent from each Lender of
its pro rata share of such Borrowing. Unless the Administrative Agent shall have
been notified by a Lender prior to 1:00 p.m. (Chicago time) on the date a
Borrowing is to be made hereunder that such Lender does not intend to make its
pro rata share of such Borrowing available to the Administrative Agent, the
Administrative Agent may assume that such Lender has made such share available
to the Administrative Agent on such date and the Administrative Agent may (but
shall not be obligated to) in reliance upon such assumption make available to
the Company a corresponding amount. If such corresponding amount is not in fact
made available to the Administrative Agent by such Lender and the Administrative
Agent has made such amount available to the Company, the Administrative Agent
shall be entitled to receive such amount from such Lender forthwith upon its
demand, together with interest thereon in respect of each day during the period
commencing on the date such amount was made available to the Company and ending
on but excluding the date the Administrative Agent recovers such amount at a
rate per annum equal to (x) from the date the related payment was due to the
Administrative Agent to the date two (2) Business Days after the date such
payment was due, the Federal Funds Rate for such day (or in the case of a day
which is not a Business Day, then for the preceding day) and (y) thereafter
until payment of such amount is received by the Administrative Agent from such
Lender, the Base Rate in effect for each such day.

Section 3.  Interest.

     Section 3.1.   Options. Subject to all of the terms and conditions of this
Section 3, portions of the principal indebtedness evidenced by the Notes (all of
the indebtedness evidenced by the Notes bearing interest at the same rate for
the same period of time being hereinafter referred to as a "Portion") shall, at
the option of the Company, bear interest with reference to the Base Rate (the
"Base Rate Portions") or with reference to the Adjusted LIBOR ("LIBOR
Portions"), and Portions shall be convertible from time to time from one basis
to the other. All of the indebtedness evidenced by the Notes which is not part
of a LIBOR Portion shall constitute

                                     -14-
<PAGE>
 
a single Base Rate Portion. All of the indebtedness evidenced by the Notes which
bears interest with reference to a particular Adjusted LIBOR for a particular
Interest Period shall constitute a single LIBOR Portion. Anything contained
herein to the contrary notwithstanding, there shall not be more than eight (8)
LIBOR Portions applicable to any Note outstanding at any one time and each
Lender shall have a ratable interest in each Portion based on its Commitment
percentage thereof. The Company promises to pay interest on each Portion at the
rates and times specified in this Section 3.

     Section 3.2.   Base Rate Portion. Each Base Rate Portion shall bear
interest (which the Company promises to pay at the times herein provided) at the
rate per annum determined by adding the Applicable Margin to the Base Rate as in
effect from time to time. Interest on the Base Rate Portions shall be payable
quarterly in arrears on the first day of each March, June, September and
December in each year and at maturity of the applicable Notes, and interest
after maturity shall be due and payable upon demand.

     Section 3.3.   LIBOR Portions. Each LIBOR Portion shall bear interest
(which the Company promises to pay at the times herein provided) for each
Interest Period selected therefor at a rate per annum equal to the Adjusted
LIBOR for such Interest Period plus the Applicable Margin. Interest on each
LIBOR Portion shall be due and payable on the last day of each Interest Period
applicable thereto and, if an Interest Period is longer than three (3) months,
then at the end of each three (3) month period and at the end of such Interest
Period, and interest after maturity shall be due and payable upon demand. The
Company shall give written or telephonic notice to the Administrative Agent
(which notice shall be irrevocable once given and, if given by telephone, shall
be promptly confirmed in writing) on or before 12:00 noon (Chicago time) on the
third Business Day preceding the end of an Interest Period applicable to a LIBOR
Portion whether such LIBOR Portion is to continue as a LIBOR Portion, in which
event the Company shall notify the Administrative Agent of the new Interest
Period selected therefor, and in the event the Company shall fail to so notify
the Administrative Agent, such LIBOR Portion shall automatically be converted
into and added to the Base Rate Portion as of and on the last day of such
Interest Period. The Administrative Agent shall promptly notify each Lender of
each notice received from the Company pursuant to the foregoing provisions.
Anything contained herein to the contrary notwithstanding, the obligation of the
Lenders to create or continue any LIBOR Portion or to convert any part of the
Base Rate Portion into a LIBOR Portion shall be conditioned upon the fact that
at the time no Default or Event of Default shall have occurred and be
continuing, except that during the existence of a Default (but not an Event of
Default) the Company may request the continuation of any LIBOR Portion into
another LIBOR Portion with an Interest Period not in excess of one (1) month.


     Section 3.4.   Computation. All interest on the Notes and all fees, charges
and commissions due hereunder shall be computed on the basis of a year of 360
days for the actual number of days elapsed, except that interest on the Base
Rate Portion shall be computed on the basis of a year of 365 or 366 days (as the
case may be) for the actual number of days elapsed.

     Section 3.5.   Manner of Rate Selection. The Company shall notify the
Administrative Agent by 12:00 noon (Chicago time) at least 3 Business Days prior
to the date upon which it requests that any LIBOR Portion be created or that any
part of the Base Rate Portion be

                                     -15-
<PAGE>
 
converted into a LIBOR Portion (such notice to specify in each instance the
amount thereof and the Interest Period selected therefor) and the Administrative
Agent shall promptly advise each Lender of each such notice. If any request is
made to convert a LIBOR Portion into the Base Rate Portion, such conversion
shall only be made so as to become effective as of the last day of the Interest
Period applicable thereto. All requests for the creation, continuance or
conversion of Portions under this Agreement shall be irrevocable. Such requests
may be written or telephonic (provided that if such notice is given by
telephone, the Company shall promptly confirm such notice to the Administrative
Agent in writing), and the Administrative Agent is hereby authorized to honor
telephonic requests for creations, continuances and conversions received by it
from any person the Administrative Agent reasonably believes to be an Authorized
Representative, the Company hereby indemnifying the Administrative Agent and the
Lenders from any liability or loss ensuing from so acting. The Company
acknowledges that, in connection with acknowledgment agreements entered into
pursuant to Section 4.10 hereof and Assignment Agreements entered into pursuant
to Section 12.12(a) hereof entered into at any time prior to the earlier of (i)
30 days after the close of the primary syndication as reasonably determined and
established by the Administrative Agent and (ii) six (6) months after the date
hereof, any LIBOR Portions which are required to be prepaid by the
Administrative Agent in connection therewith (in order for Loans and credit
risks with respect to Letters of Credit then outstanding to be shared ratably by
the Lenders in accordance with their adjusted Commitments) shall be accompanied
by any payments required to be paid to the Lenders under Section 3.6 hereof.

     Section 3.6.   Funding Indemnity. In the event any Lender shall incur any
loss, cost or expense (including, without limitation, any loss, cost or expense
incurred by reason of the liquidation or re-employment of deposits or other
funds acquired by such Lender to fund or maintain any LIBOR Portion or the
relending or reinvesting of such deposits or amounts paid or prepaid to such
Lender, but excluding any loss of profit) as a result of:

               (a) any payment or prepayment of a LIBOR Portion on a date other
     than the last day of its Interest Period for any reason, whether before or
     after default, and whether or not such payment is required by any of the
     provisions of this Agreement;

               (b) any failure (because of a failure to meet the conditions of
     Section 7 hereof or otherwise) by the Company to create, borrow, continue
     or effect by conversion a LIBOR Portion on the date specified in a notice
     given pursuant to this Agreement hereof; or

               (c) any failure by the Company to make any payment of principal
     on any LIBOR Portion when due (whether by acceleration, mandatory
     prepayment or otherwise),

then, upon the demand of such Lender, the Company shall pay to such Lender such
amount as will reimburse such Lender for such loss, cost or expense. If any
Lender makes such a claim for compensation, it shall provide to the Company a
certificate executed by an officer of such Lender setting forth the amount of
such loss, cost or expense in reasonable detail (including an explanation of the
basis for and the computation of such loss, cost or expense) and such
certificate shall be deemed prima facie correct.

     Section 3.7.   Change of Law. Notwithstanding any other provisions of this
Agreement or any Note, if at any time any change in applicable law or regulation
or in the official interpretation thereof makes it unlawful for any Lender to
make or continue to maintain LIBOR Portions or to give effect to its obligations
to make LIBOR Portions available as contemplated hereby, such Lender shall
promptly give notice thereof to the Company and the Administrative Agent and
such Lender's obligations to make or maintain LIBOR Portions under this
Agreement shall be suspended until it is no longer unlawful for such Lender to
make or maintain LIBOR Portions. To the extent it is unlawful for any such
Lender to maintain any such LIBOR Portions, the Company shall prepay on demand
the outstanding principal amount of any such affected LIBOR Portions, together
with all interest accrued thereon and all other amounts then due and payable to
such Lender under this Agreement; provided, however, subject to all of the terms
and conditions of this Agreement, the Company may then elect to convert the
principal amount of the affected LIBOR Portion from such Lender into the Base
Rate Portion from such Lender that shall not be made ratably by the Lenders but
only from such affected Lender. During the period when it is unlawful for any
Lender to make LIBOR Portions, Loans shall continue to be made in such a manner
so that the percentage of each Lender's Commitment in use is identical, but the
Lenders affected by such illegality shall make their share of each Borrowing
which has been requested in the form of a LIBOR Portion available in the form of
a Base Rate Portion. Each Lender agrees (to the extent consistent with its
internal policies) to designate a different lending office if such designation
would avoid the illegality described in this Section 3.7; provided, however,
that such designation need not be made if it would result in any additional
costs, expenses or risks to such Lender that are not reimbursed by the Company
pursuant hereto or would, in the reasonable judgment of such Lender, be
otherwise disadvantageous to such Lender.

     Section 3.8.   Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any LIBOR Portion the Administrative Agent determines that deposits in United
States Dollars (in the applicable amounts) are not being offered to it or to
banks generally in the offshore eurodollar market for such Interest Period, then
the Administrative Agent shall forthwith give notice thereof to the Company and
the Lenders, whereupon until the Administrative Agent notifies the Company that
the circumstances giving rise to such suspension no longer exist, the
obligations of the Lenders to make any further LIBOR Portions available shall be
suspended.

     Section 3.9.  Increased Cost and Reduced Return. If, on or after the date
hereof, the adoption of any applicable law, rule or regulation, or any change
therein, or any change in the official interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its lending office) with any request or directive (whether or not having the
force of law) of any such authority, central bank or comparable agency:

               (a) shall subject any Lender (or its lending office) to any
     charges of any kind (other than Withholding Taxes covered by Section 4.9
     hereof) with respect to its interest in the LIBOR Portions, its Note or its
     obligation to make LIBOR Portions available, or shall change the basis of
     taxation of payments to any Lender (or its lending office) of the principal
     of or interest on LIBOR Portions or any other amounts due under this
     Agreement in respect of its LIBOR Portions or its obligation to make LIBOR
     Portions; or

                                     -17-
<PAGE>
 
               (b) shall impose, modify or deem applicable any reserve, special
     deposit or similar requirements (including, without limitation, any such
     requirement imposed by the Board of Governors of the Federal Reserve
     System, but excluding any such requirement included in an applicable
     Eurodollar Reserve Percentage) against assets of, deposits with or for the
     account of, or credit extended by, any Lender (or its lending office) or
     shall impose on any Lender (or its lending office) or the offshore
     interbank market any other condition affecting LIBOR Portions, its Note or
     its obligation to make LIBOR Portions available;

and the result of any of the foregoing is to increase the cost to such Lender
(or its lending office) of making or maintaining any LIBOR Portion, or to reduce
the amount of any sum received or receivable by such Lender (or its lending
office) under this Agreement or under its Note with respect thereto, by an
amount deemed by such Lender to be material, then, within 30 days after demand
by such Lender (with a copy to the Administrative Agent), the Company shall pay
to such Lender such additional amount or amounts as will compensate such Lender
for such increased cost or reduction. A certificate of any Lender claiming
compensation under this Section 3.9 and setting forth the additional amount or
amounts in reasonable detail (including an explanation of the basis therefor and
the computation of such amount) to be paid to it hereunder shall be deemed prima
facie correct. In determining such amount, such Lender may use reasonable
averaging and attribution methods. A Lender shall not be entitled to
compensation under this Section 3.9 with respect to any adoption or change for
any period prior to the earlier of (i) the date it notifies the Company of the
adoption or change giving rise to the request for compensation or (ii) the date
which is 30 days prior to the date it becomes aware of the adoption or change
giving rise to the request for compensation if the Company is notified of the
adoption or change prior to the lapse of such 30-day period.

     Section 3.10.  Lending Offices. Each Lender may, at its option, elect to
make its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof (each a "lending office") or at such other of
its branches, offices or affiliates as it may from time to time elect and
designate in a notice to the Company and the Administrative Agent (but such
funds shall in any event be made available to the Company at the office of the
Administrative Agent as herein provided for).

     Section 3.11.  Discretion of Banks as to Manner of Funding. Notwithstanding
any other provision of this Agreement, each Lender shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations under this Agreement (including, without limitation, calculations
under Sections 3.6 and 3.9 hereof) shall be made as if each Lender had actually
funded and maintained its interest in each LIBOR Portion through the purchase of
deposits in the offshore interbank market having a maturity corresponding to
such LIBOR Portion's Interest Period and bearing an interest rate equal to LIBOR
for such Interest Period.

Section 4.  Fees, Payments, Reductions, Applications, Notations and Extensions.

     Section 4.1.   Commitment Fee. For the period from the date hereof to and
including the Termination Date, the Company shall pay to the Administrative
Agent for the ratable account of 

                                     -18-
<PAGE>
 
the Lenders a commitment fee at the Applicable Margin on the average daily
unused amount of the Commitments hereunder (provided that, if the average daily
unused amount of the Commitments for the most recently completed three (3)-month
period (or such shorter period from the date of this Agreement through the first
payment date thereof) plus the daily unused amount of the commitments available
under the Five-Year Credit Agreement for such period is greater than 50% of the
Commitments available hereunder and the commitments available under the Five-
Year Credit Agreement for such period, then such fee shall be paid at .125% plus
the Applicable Margin for the commitment fee), such fee to be payable quarterly
in arrears on the first day of each March, June, September and December in each
year to and including, and on, the Termination Date.

     Section 4.2. Administrative Agent's Fees'. On the date hereof, and on the
date occurring on each anniversary of the date hereof (excluding the Termination
Date) when any credit or commitment to extend credit is outstanding hereunder,
the Company shall pay to the Administrative Agent, for its own use and benefit,
such fees as set forth in the administrative agent's fee letter dated the date
hereof, as such fees may be amended by the Company and the Administrative Agent
from time to time.

     Section 4.3. Underwriting Fees. The Company shall pay to the Lead
Arrangers, Book Managers, and Syndication Agents such underwriting, acceptance
and ticking fees as set forth in the Fee and Structuring Letter.

     Section 4.4. Payments. (a) Maturity. The Company shall repay all Loans in
full on the Termination Date, together with all accrued but unpaid interest
thereon, provided that, if the Term Credit option provided for in Section 2.3
hereof has been selected and all conditions to the effectiveness thereof
satisfied, the final maturity of the Loans shall be extended to the Term Credit
Final Maturity Date at which time the Company shall repay all Loans in full
together with accrued but unpaid interest thereon.

     (b) Mandatory Prepayments. In the event that at any time the aggregate
amount of Loans then outstanding exceeds the Commitments then in effect, the
Company shall immediately upon demand pay over the amount of the excess to the
Administrative Agent to be applied against the Loans.

     (c) Optional Prepayments. The Company shall have the privilege of prepaying
without premium or penalty and in whole or in part (but, if in part, then in an
amount not less than $1,000,000) (or such lesser amount as will prepay the Loans
in full) the Notes at any time, each such prepayment to be made by the payment
of the principal amount to be prepaid, any amount due the Lenders under Section
3.6 hereof (any failure of the Administrative Agent or the Lenders to require
payment of any amount due under Section 3.6 not to preclude a later demand that
the amount so due be paid) and, in the case of a prepayment which prepays the
Notes in full after which the Commitments are no longer outstanding, accrued
interest thereon to the date fixed for prepayment.

     (d) Any amount of Loans outstanding under the Revolving Credit paid or
prepaid prior to the Termination Date may, subject to the terms and conditions
of this Agreement, be
                                     -19-
<PAGE>
 
borrowed, repaid, and borrowed again. No amount of Loans paid or prepaid on or
after the Termination Date may be reborrowed.

     Section 4.5.   Terminations. The Company shall have the privilege at any
time and from time to time upon five (5) Business Days prior notice to the
Administrative Agent (which shall promptly notify the Lenders) to ratably
terminate the Commitments in whole or in part (but, if in part, then in a
minimum amount of $1,000,000), provided that the Commitments may not be reduced
to an amount less than the aggregate principal amount of Loans then outstanding
(except in connection with the Term Credit election pursuant to Section 2.3
hereof). No termination of the Commitments may be reinstated unless otherwise
agreed to in writing by the Lenders.

     Section 4.6.   Place and Application. All payments of principal, interest
and fees shall be made to the Administrative Agent at its office at 115 South
LaSalle Street, Chicago, Illinois (or at such other place as the Administrative
Agent may specify) in immediately available and freely transferable funds at the
place of payment. All payments due from the Company hereunder shall be made
without set-off or counterclaim and without reduction for, and free from, any
and all present or future taxes, levies, imposts, duties, fees, charges,
deductions, withholdings, restrictions or conditions of any nature imposed by
any government or political subdivision or taxing authority thereof. Payments
received by the Administrative Agent after 1:00 p.m. (Chicago time) shall be
deemed received as of the opening of business on the next Business Day. Except
as otherwise provided in this Agreement, all payments shall be received by the
Administrative Agent for the ratable account of the Lenders, and shall be
promptly distributed by the Administrative Agent ratably to the Lenders except
that payments which pursuant to the terms hereof are for the use and benefit of
the Administrative Agent shall be retained by it for its own account and
payments received to reimburse a Lender for a fee or cost peculiar to that
Lender shall be remitted to it. Unless the Company otherwise directs, principal
payments on the Notes shall be first applied to the Base Rate Portion and then
to the LIBOR Portions in the order in which their Interest Periods expire.

     Anything contained herein to the contrary notwithstanding, all payments and
collections received in respect of the indebtedness evidenced by the Notes by
the Administrative Agent or any of the Lenders after an Event of Default has
occurred and is continuing shall be distributed as follows:

               (a)  first, to the payment of any outstanding costs and expenses
     incurred by the Administrative Agent in protecting, preserving or enforcing
     rights under the Loan Documents and in any event including all costs and
     expenses of a character which the Company has agreed to pay under Section
     12.10 hereof (such funds to be retained by the Administrative Agent for its
     own account unless it has previously been reimbursed for such costs and
     expenses by the Lenders, in which event such amounts shall be remitted to
     the Lenders to reimburse them for payments theretofore made to the
     Administrative Agent); and

               (b)  second, to the remaining Obligations.

                                     -20-

     Section 4.7.   Notations and Requests. All advances made against the Notes
shall be recorded by the Lenders on their books or, at their option in any
instance, endorsed on the reverse side of the Notes and the unpaid principal
balances so recorded or endorsed by the Lenders shall be prima facie evidence in
any court or other proceeding brought to enforce the Notes of the principal
amount remaining unpaid thereon. Prior to any negotiation of any Note, the
Lender holding such Note shall endorse thereon the principal amount remaining
unpaid thereon.

     Section 4.8.   Capital Adequacy. If any Lender shall determine that any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof or compliance by such Lender (or its
lending office) with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on such Lender's capital as a consequence of its obligations hereunder or the
Letters of Credit or credit extended by it hereunder to a level below that which
such Lender could have achieved but for such law, rule, regulation, change or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy) by an amount deemed by such Lender to be material, then from
time to time as specified by such Lender the Company shall pay such additional
amount or amounts as will compensate such Lender for such reduction in rate of
return. A certificate of any Lender claiming compensation under this Section and
setting forth the additional amount or amounts to be paid to it hereunder in
reasonable detail shall be deemed prima facie correct. In determining such
amount, such Lender may use any reasonable averaging and attribution methods. A
Lender shall not be entitled to compensation under this Section with respect to
any change, adoption or interpretation (a "Change") for any period prior to the
earlier of (i) the date it notifies the Company of the Change or (ii) the date
which 30 days prior to the date such Lender obtains actual knowledge of the
Change giving rise to the request for compensation if the Company is notified of
the Change prior to the lapse of such 30-day period. Each Lender and the
Administrative Agent shall use reasonable efforts to minimize the cost imposed
on the Company in respect of any such increased capital requirement and shall
compute the assessment of any such cost related to such increased capital on a
nondiscriminatory basis among the Company, on the one hand, and other borrowers
to which it applies, on the other hand, and neither such Lender nor any
corporation controlling such Lender nor the Administrative Agent shall be
entitled to demand compensation or be compensated for any increased capital
requirement from the Company hereunder in excess of the amount so computed.

     Section 4.9.  Withholding Taxes. (a) Payments Free of Withholding. Except
as otherwise required by law and subject to Section 4.9(b) hereof, each payment
by the Company under this Agreement or the other Loan Documents shall be made
without withholding for or on account of any present or future taxes (other than
overall net income taxes on the recipient) imposed by or within the jurisdiction
in which the Company is domiciled, any jurisdiction from which the Company makes
any payment, or (in each case) any political subdivision or taxing authority
thereof or therein; provided, however, that the Company shall not be required to
indemnify or gross up the payments to any Lender under this Section 4.9(a) in
respect of United States federal withholding tax to the extent that the
obligation to indemnify or gross up such payments would not have arisen but for
such Lender's failure to comply with Section 4.9(b). If any such

                                     -21-
<PAGE>
 
withholding is so required, the Company shall make the withholding, pay the
amount withheld to the appropriate governmental authority before penalties
attach thereto or interest accrues thereon and forthwith pay such additional
amount as may be necessary to ensure that the net amount actually received by
each Lender and the Administrative Agent free and clear of such taxes (including
such taxes on such additional amount) is equal to the amount which that Lender
or the Administrative Agent (as the case may be) would have received had such
withholding not been made. If the Administrative Agent or any Lender pays any
amount in respect of any such taxes, penalties or interest, the Company shall
reimburse the Administrative Agent or such Lender for that payment on demand in
the currency in which such payment was made. If the Company pays any such taxes,
penalties or interest, it shall deliver official tax receipts evidencing that
payment or certified copies thereof to the Lender or Administrative Agent on
whose account such withholding was made (with a copy to the Administrative Agent
if not the recipient of the original) on or before the thirtieth day after
payment.
     
     (b)  U.S. Withholding Tax Exemptions. Each Lender that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) shall
submit to the Company and the Administrative Agent on or before the date the
initial Loans are is made hereunder or, if later, the date such financial
institution becomes a Lender hereunder, two duly completed and signed copies of
(i) either Form 1001 (relating to such Lender and entitling it to a complete
exemption from withholding under the Code on all amounts to be received by such
Lender, including fees, pursuant to the Loan Documents and the Obligations) or
Form 4224 (relating to all amounts to be received by such Lender, including
fees, pursuant to the Loan Documents and the Obligations) of the United States
Internal Revenue Service or (ii) solely if such Lender is claiming exemption
from United States withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any successor
form prescribed by the Internal Revenue Service, and a certificate representing
that such Lender is not a bank for purposes of Section 881(c) of the Code, is
not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the
Code) of the Company and is not a controlled foreign corporation related to the
Company (within the meaning of Section 864(d)(4) of the Code). Thereafter and
from time to time, each Lender shall submit to the Company and the
Administrative Agent such additional duly completed and signed copies of one or
the other of such Forms (or such successor forms as shall be adopted from time
to time by the relevant United States taxing authorities) and such other
certificates as may be (i) requested by the Company in a written notice,
directly or through the Administrative Agent, to such Lender and (ii) required
under then-current United States law or regulations to avoid or reduce United
States withholding taxes on payments in respect of all amounts to be received by
such Lender, including fees, pursuant to the Loan Documents or the Obligations.
Upon the request of the Company or the Administrative Agent, each Lender that is
a United States person (as such term is defined in Section 7701(a)(30) of the
Code) shall submit to the Company and the Administrative Agent a certificate to
the effect that it is such a United States person.

     (c)  Inability of Lender to Submit Forms. If any Lender determines, as a
result of any change in applicable law, regulation or treaty, or in any official
application or interpretation thereof, that it is unable to submit to the
Company or the Administrative Agent any form or certificate that such Lender is
obligated to submit pursuant to subsection (b) of this Section 4.9 or that such
Lender is required to withdraw or cancel any such form or certificate previously

                                     -22-
<PAGE>
 
submitted or any such form or certificate otherwise becomes ineffective or
inaccurate, such Lender shall promptly notify the Company and Administrative
Agent of such fact and the Lender shall to that extent not be obligated to
provide any such form or certificate and will be entitled to withdraw or cancel
any affected form or certificate, as applicable.

     Section 4.10.  Increase in Commitments. At any time prior to 30 days after
the close of the primary syndication as reasonably determined and established by
the Administrative Agent, in the event that sufficient commitments are received
from banks and other financial institutions (other than Bank of Montreal and
Bank of America National Trust and Savings Association (herein, the "Initial
Lenders")), such that the Initial Lenders remaining Commitments, after giving
effect to the syndication of the credit facilities provided for herein, are at
their desired initial hold levels, and the aggregate Commitments hereunder and
commitments under the Five-Year Credit Agreement exceed $250,000,000 (such
excess being referred to herein as the "Overage"), then in that event the
Administrative Agent shall notify the Company of the Overage, and the Company
may request that the aggregate Commitments hereunder be increased by the lesser
of $20,000,000 and 40% of the Overage by offering such increase to one or more
banks or other financial institutions (each such bank or financial institution
being hereinafter referred to as an "Additional Lender") selected by the Company
and acceptable to the Lead Arrangers, Book Managers, and Syndication Agents and
the Administrative Agent. Such increase in the Commitments shall also be subject
to the satisfaction of the following conditions: (a) each such increase shall be
at least $2,000,000 or such greater amount which is an integral multiple
$1,000,000; (b) the Administrative Agent shall have received an acknowledgement
agreement providing for such increase in form and substance satisfactory to it
executed by the Company, the Administrative Agent, and the relevant Additional
Lender; and (c) the Administrative Agent shall have received a Note duly
executed by the Company in favor of the relevant Additional Lender. Upon the
satisfaction of such conditions, effective as of the date set forth above in
such acknowledgement agreement, each such Additional Lender shall thereafter be
a "Lender" party to this Agreement and shall be entitled to all rights, benefits
and privileges afforded a Lender hereunder and subject to the obligations of a
Lender hereunder to the extent of its Commitment and Exhibit A shall be deemed
amended reflecting the increase in the aggregate Commitments caused by the
inclusion of the Commitment of the Additional Lender. Concurrently with the
effectiveness of such increase, each Additional Lender shall fund its percentage
of the outstanding Loans to the Administrative Agent so that after giving effect
thereto each Lender, including the Additional Lender, holds a pro rata share (in
accordance with its Commitment percentage) of the outstanding Loans and the
Company shall pay to each Lender all amounts due under Section 3.6 hereof as a
result of any prepayment of any outstanding LIBOR Portions of the Loans.

     Section 4.11.  Extensions of Commitments. Not less than 45 days nor more
than 60 days prior to the Termination Date then in effect, the Company may
advise the Administrative Agent in writing of its desire to extend the
Termination Date for an additional 364 days from the Termination Date then in
effect and the Administrative Agent shall promptly notify the Lenders of each
such request. Each Lender shall notify the Administrative Agent in writing not
later than 30 days before the Termination Date then in effect whether such
Lender agrees to the requested extension. No Lender shall be under any
obligation or commitment to extend such date and no such obligation or
commitment on the part of any Lender shall be inferred from the provisions of

                                     -23-
<PAGE>
 
this Section (it being understood that any Lender may accept or decline such a
request in its sole discretion and on such terms as such Lender may elect).
Failure on the part of any Lender to respond to such a request by the required
date set forth above shall be deemed to be a denial of such request by such
Lender. The requested extension shall not be granted unless Lenders holding
Commitments aggregating at least 80% of the aggregate Commitments in effect at
such time shall have consented in writing to such extension. If Lenders holding
100% of the aggregate Commitments consent to such extension, the Termination
Date will be automatically extended for an additional 364 day period. If Lenders
holding Commitments aggregating less than 100%, but equal to or greater than
80%, of the aggregate Commitments consent to such extension, the Company may
elect by written notice to the Administrative Agent prior to the current
Termination Date to (i) rescind the original request, in which case there shall
be no extension of the Termination Date pursuant to this Section (it being
understood that the Company may elect to exercise the Term Credit option in
accordance with the terms and conditions of Section 2.3 hereof), (ii) continue
the credit facilities provided for herein for such additional period with
respect to the Commitments of the consent Lenders, with the Commitment of any
Lender who has not consented to such extension (herein, a "Non-Consenting
Lender") to be terminated on the current Termination Date currently in effect
(at which time all Obligations of such Non-Consenting Lender shall be paid and
satisfied in full by the Company), or (iii) require any such Non-Consenting
Lender to transfer and assign its Commitment and its other interests, rights,
and obligations under the Loan Documents to another bank or financial
institution willing to provide such extended financing in accordance with
Section 4.12 hereof. The Administrative Agent shall provide prompt notice to the
Company and the Lenders in writing as to whether the requested extension has
been granted and, if applicable, the list of Non-Consenting Lenders. In the
event the Administrative Agent requests, the Company and the Lenders shall
execute and deliver such documents as the Administrative Agent may deem
necessary or appropriate to reflect any such extension, and all costs and
expenses incurred by the Administrative Agent in connection therewith shall be
paid by the Company.

     Section 4.12.  Substitution of Lenders. Upon the receipt by the Company of
(a) a claim from any Lender for compensation under Sections 3.9, 4.8, or 4.9
hereof, (b) notice by any Lender to the Company of any illegality pursuant to
Section 3.7 hereof, or (c) notice from the Administrative Agent that a Lender or
Lenders have not approved an extension of the Termination Date pursuant to
Section 4.11 hereof (any such Lender referred to in clause (a), (b), or (c)
above being hereinafter referred to as an "Affected Lender"), the Company may
require, at its expense, any such Affected Lender to assign, at par plus accrued
interest and fees, without recourse, all of its interest, rights and obligations
hereunder (including all of its Commitment, Loans and other amounts at any time
owing to it hereunder and the other Loan Documents) to a bank or financial
institution specified by the Company, provided that (i) such assignment shall
not conflict with or violate any law, rule, or regulation or order of any court
or other governmental authority, (ii) the Company shall have received the
written consent of the Administrative Agent, which consent shall not be
unreasonably withheld, to such assignment, (iii) the Company shall have paid to
the Affected Lender all monies (together with amounts due such Affected Lender
under Section 3.6 hereof as if the Loans owing it were prepaid rather than
assigned), other than such principal, interest and fees accrued and owing to it
hereunder, and (iv) the assignment is entered into in accordance with the other
requirements of Section 12.12 hereof.

Section 5.  Guaranties.

     Section 5.1.   Guaranty. Payment of the Obligations hereunder and under the
other Loan Documents shall at all times be jointly and severally guaranteed
pursuant to Section 11 hereof by MK-Ohio and Washington and from time to time
such other Restricted Subsidiaries (the "Necessary Parties") so that as of the
end of each fiscal quarter of the Company the assets of the Company, MK-Ohio,
Washington and the Necessary Parties are not less than 90% of the assets of the
Company and all of its Restricted Subsidiaries taken as a whole at such time.
The Company shall cause each Necessary Party to execute a supplement to the
guaranty provided in Section 11 hereof pursuant to which such Restricted
Subsidiary joins in and becomes obligated as a guarantor hereunder, which
supplement shall be in the form attached hereto as Exhibit C or in such other
form satisfactory to the Administrative Agent (MK-Ohio, Washington and the from
time to time Necessary Parties are herein collectively referred to as the
"Guarantors" and each individually as a "Guarantor"). The Company shall also
cause such Guarantor to execute and deliver, at the Company's cost and expense,
such other instruments, documents, certificates and opinions required by the
Administrative Agent in connection therewith.

Section 6.  Representations and Warranties.

     The Company represents and warrants to the Lenders as follows:

     Section 6.1.   Organization and Power. The Company is duly organized and
existing under the laws of the state of its incorporation, and is duly licensed
or qualified to do business in each state where the nature of the assets owned
or leased by it or business conducted by it requires such licensing or
qualification and in which the failure to be so licensed or qualified would have
a Material Adverse Effect and has all necessary corporate power to carry on its
present business. The Company has full right, power and authority to enter into
this Agreement, to make the borrowings herein provided for, to issue the Notes
in evidence thereof, to execute and deliver the other Loan Documents executed
and delivered or to be executed and delivered by it, and to perform each and all
of the matters and things herein and therein provided for. Each Guarantor has
full right, power and authority to enter into the Loan Documents executed by it
and to perform each and all of the matters and things therein provided for. The
Loan Documents do not, nor will the performance or observance by the Company or
any Subsidiary of any of the matters and things herein or therein provided for,
contravene any provision of law or any charter or by-law provision of the
Company or any such Subsidiary or constitutes a breach or default under any
covenant, indenture or agreement of or affecting the Company or any such
Subsidiary where such breach or default would have a Material Adverse Effect.

     Section 6.2.   Subsidiaries. Each Subsidiary is duly organized and existing
under the laws of the jurisdiction of its incorporation or organization, and is
duly licensed or qualified to do business in each state or other jurisdiction
where the nature of the assets owned or leased by it or business conducted by it
requires such licensing or qualification and in which the failure to be so
licensed or qualified would have a Material Adverse Effect and has all necessary
power to carry on its present business. Schedule 6.2 hereto identifies each
Subsidiary, the jurisdiction of its incorporation or organization, the
percentage of issued and outstanding shares of each class of its capital stock
or other equity interests owned by the Company and the Subsidiaries and, if such

                                     -25-
<PAGE>
 
percentage is not 100% (excluding directors' qualifying shares as required
by law), a description of each class of its authorized capital stock or other
equity interests and the number of shares of each class issued and outstanding,
together with a designation of those Subsidiaries which are Restricted
Subsidiaries (including a designation of those which are Material Subsidiaries)
and those which are Unrestricted Subsidiaries. All of the outstanding shares of
capital stock or other equity interests of each Subsidiary are validly issued
and outstanding and fully paid and nonassessable, and all shares of each
Subsidiary indicated on Schedule 6.2 as owned by the Company or a Subsidiary are
owned, beneficially and of record, by the Company or such Subsidiary free and
clear of all liens, security interests, charges and encumbrances. There are no
outstanding commitments or other obligations of any Subsidiary to issue, and no
options, warrants or other rights of any Person to acquire, any shares of any
class of capital stock or other equity interests of any Subsidiary, except for
options granted in the ordinary course to officers and employees of non-Material
Subsidiaries or of Unrestricted Subsidiaries which, as to any Subsidiary, do
not, if exercised, aggregate 10% or more of the capital stock of any such
Subsidiary.

     Section 6.3. Use of Proceeds; Regulation U. The Company shall use proceeds
of the Loans and other extensions of credit made available hereunder solely for
the purpose of refinancing existing debt of the Company and its Subsidiaries,
for the acquisition of the Acquired Assets, and for its working capital and
other general corporate purposes. Neither the Company nor any Subsidiary is
engaged in the business of extending credit for the purpose of purchasing or
carrying margin stocks (within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System), and no part of the proceeds of any
loan or extension of credit hereunder will be used to purchase or carry any
margin stock or extend credit to others for the purpose of purchasing or
carrying any margin stock if as a result thereof such loan or other extension of
credit would violate Regulation U or any interpretation thereof.

     Section 6.4. Financial Statements. (a) The financial statements of the
Company and its Subsidiaries for the year ended November 30, 1998, including an
audited consolidated balance sheet as of November 30, 1998, and an audited
consolidated statement of profit and loss and statement of cash flows for the
twelve months ended said date, prepared by the Company, and heretofore furnished
to the Lenders, truly and accurately reflect the financial condition of the
Company and its Subsidiaries taken as a whole as at said date and the results of
operations and cash flows for the period covered thereby. Except as disclosed on
Schedule 6.4 hereof, the Company and its Subsidiaries have no contingent
liabilities which are material to them other than as indicated on said financial
statements and, since the date of such financial statements, there have been no
material adverse changes in the condition, financial or otherwise, business or
operations of the Company or its Subsidiaries taken as a whole.

     (b) The unaudited pro forma combined, condensed, and consolidated balance
sheet and combined, condensed, and consolidated statements of operations for the
Company and its Subsidiaries heretofore delivered to the Lenders fairly present
(subject to the qualifications and assumptions set forth in the notes attached
thereto) the combined financial condition of the Company and its Subsidiaries as
at the dates thereof and for the periods covered thereby.

                                     -26-
<PAGE>
 
     Section 6.5. Litigation and Taxes. Except as disclosed on Schedule 6.4
hereof, there is no litigation or governmental proceeding pending, nor to the
knowledge of the Company threatened, against the Company or any Subsidiary which
could reasonably be expected to result in a Material Adverse Effect. The income
tax returns of the Company and its Subsidiaries for the taxable year ended
November 30, 1998 and for all taxable years ended prior to said date, have been
filed or extended with the appropriate governmental or taxing authorities, and
any additional assessments in connection with any such years have been paid or
the applicable statute of limitations therefor has expired. No objections to or
controversies in respect of the income tax returns of the Company or any
Subsidiary are pending or threatened which could reasonably be expected to
result in a Material Adverse Effect. No authorization, consent, license, or
exemption from, or filing or registration with, any court or governmental
department, agency or instrumentality, is or will be necessary to the valid
execution, delivery or performance by the Company or any Subsidiary of any Loan
Document to be executed and delivered by it.

     Section 6.6. Burdensome Contracts with Affiliates . Neither the Company nor
any Subsidiary is a party to any material contracts or agreements with any of
its Affiliates on terms and conditions which are materially less favorable to
the Company or such Subsidiary than would be usual and customary in similar
contracts or agreements between Persons not affiliated with each other.

     Section 6.7. ERISA. The Company and each Subsidiary are each in compliance
in all material respects with the Employee Retirement Income Security Act of
1974, as amended ("ERISA") to the extent applicable to it and has received no
notice to the contrary from the Pension Benefit Guaranty Corporation ("PBGC"),
and, in the event of the Company's or any Subsidiary's partial or complete
withdrawal from any pension plans or multiemployer pension plans subject to
Title IV of ERISA or termination of any other pension plans subject to Title IV
of ERISA, the liability of the Company and its Subsidiaries for any unfunded
vested benefits thereunder could not reasonably be expected to result in a
Material Adverse Effect.

     Section 6.8. Full Disclosure. The statements and information furnished to
the Lenders in connection with the negotiation of this Agreement and the
commitments by the Lenders to provide all or part of the financing contemplated
hereby do not, taken as a whole, contain any untrue statement of a material fact
or omit a material fact necessary to make the material statements contained
therein or herein not misleading, except for such thereof as were corrected in
subsequent written statements furnished the Lenders (the Lenders acknowledging
that as to any projections furnished to Lenders, the Company only represents
that the same were prepared on the basis of information and estimates it
believes to be reasonable). There is no fact peculiar to the Company or any
Subsidiary which the Company has not disclosed to the Lenders in writing which
materially adversely affects nor, so far as the Company now can reasonably
foresee, is reasonably likely to have a Material Adverse Effect.

     Section 6.9. Compliance with Law. (a) Except as disclosed on Schedule 6.4
hereof, neither the Company nor any Subsidiary is (i) in default in any material
respect with respect to any order, writ, injunction or decree of any court or
(ii) in default in any material respect under any law, ordinance, order,
regulation, license or demand (including ERISA, the Occupational Safety and
Health Act of 1970 and laws and regulations establishing quality criteria and

                                     -27-
<PAGE>
 
standards for air, water, land and toxic waste) of any federal, state, municipal
or other governmental agency, default with respect to or under which is
reasonably likely to result in a Material Adverse Effect; and (b) the Company
and each Subsidiary are each in compliance with all applicable state and federal
environmental, health and safety statutes and regulations, including, without
limitation, regulations promulgated under the Resource Conservation and Recovery
Act of 1976, 42 U.S.C. (S)(S)6901 et seq., except where failure to be in
compliance is reasonably likely not to have a Material Adverse Effect, and, to
the Company's knowledge, neither the Company nor any Subsidiary will have
acquired, incurred or assumed, directly or indirectly, any contingent liability
in connection with the release of any toxic or hazardous waste or substance into
the environment which is reasonably likely to have a Material Adverse Effect.
Insofar as known to the responsible officers of the Company, neither the Company
nor any Subsidiary is liable, in whole or in part, for, nor are any of the
assets or property of the Company or any Subsidiary subject to a lien in favor
of any governmental entity for any material liability arising from or in any way
relating to, the costs of cleaning up, remediating or responding a release of
hazardous substances (including, without limitation, petroleum, its by-products
or derivatives, or other hydrocarbons) except as specifically disclosed in the
10-K Statement of the Company dated November 30, 1998.

     Section 6.10. Governmental Authority and Licensing. The Company and its
Subsidiaries have received all licenses, permits, and approvals of all Federal,
state, local, and foreign governmental authorities, if any, necessary to conduct
their business, in each case where the failure to obtain or maintain the same is
reasonably likely to have a Material Adverse Effect. No investigation or
proceeding which, if adversely determined, is reasonably likely to result in
revocation or denial of any material license, permit, or approval is pending or,
to the knowledge of the Company, threatened.

     Section 6.11. Investment Company; Public Utility Holding Company. Neither
the Company nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended, or a "public utility holding company" within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

     Section 6.12. Year 2000 Compliance. The information contained in this
Section 6.12 is a YEAR 2000 READINESS DISCLOSURE. The Company (a) is conducting
a comprehensive review and assessment of the computer applications of the
Company and its Subsidiaries and is making inquiries of its material suppliers,
service vendors (including data processors) and customers, with respect to any
defect in computer software, data bases, hardware, controls and peripherals
related to the occurrence of the year 2000 or the use at any time of any date
which is before, on and after December 31, 1999, in connection therewith, (b)
has developed a plan and timeline for addressing Year 2000 Problems on a timely
basis, and (c) is implementing the plan referred to in clause (b) above in
accordance with the timetable referred to therein. The completion of the
inventory phase of the plan has exceeded the original target timetable; however,
the Company believes that the project completion target date remains achievable.
Based upon the results of its comprehensive review and assessment to date, the
Company is not aware of any Year 2000 Problem that could reasonably be expected
to have a Material Adverse Effect.

                                     -28-

     Section 6.13. Purchase Agreement. The Company has entered into one or more
agreements and instruments (collectively, the "Purchase Agreement") relating to
its acquisition of the Acquired Assets from CBS Corporation and/or one of more
of its affiliates (herein, the "Seller"), which Purchase Agreement is on terms
and conditions substantially the same as disclosed to the Lenders in the
Company's January 1999 Rating Agency Presentation (the "Rating Agency
Presentation") or otherwise disclosed to the Lenders in writing on or prior to
the date hereof. The Purchase Agreement has not been amended or modified in any
material respect and no material condition to the effectiveness thereof or the
obligations of the Company or the Seller thereunder has been waived except to
the extent disclosed in writing to the Lenders on or prior to the date hereof.
The Company has all necessary right, power, and authority to consummate the
transactions contemplated by the Purchase Agreement and to perform all of its
obligations thereunder. The Purchase Agreement has been duly authorized,
executed, and delivered by the Company and constitutes the valid and binding
obligation of the Company enforceable against it in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency, fraudulent
conveyance or similar laws affecting creditors' rights generally and general
principles of equity (regardless of whether the application of such principles
is considered in a proceeding in equity or at law); and the Purchase Agreement
does not, nor does the observance or performance by the Company of any of the
matters and things therein provided for, (a) contravene or constitute a default
under any provision of law or any judgment, injunction, order, or decree binding
upon the Company or any provision of the articles of incorporation or by-laws of
the Company, (b) contravene or constitute a default under any covenant,
indenture, or agreement of or affecting the Company or any of its Property where
such contravention or default is reasonably likely to have a Material Adverse
Effect, (c) result in the creation or imposition of any lien, charge, or
encumbrance on any of the Company's Property. No authorization, consent,
license, or exemption from, or filing or registration with, any court or
governmental department, agency, or instrumentality, nor any approval or consent
of any other Person, is or will be necessary to the valid execution, delivery,
or performance by the Company of the Purchase Agreement or of any other
instrument or document executed and delivered in connection therewith, except
for such thereof that have heretofore been obtained and remain in full force and
effect and those the failure of which to obtain or make would not materially
impair the ability of the Company to perform its obligations under the Purchase
Agreement. The Company is not in default in any material respect of its
obligations under the Purchase Agreement. Upon the funding of the purchase price
under the Purchase Agreement, the Company shall have acquired the Acquired
Assets free and clear of all liens, charges and encumbrances. Neither the
Company nor any Subsidiary (including any GESCO Subsidiary) will incur or assume
any material direct or contingent liabilities in connection with the purchase of

Restricted Subsidiary to, issue, incur, assume, create, or have outstanding any

SECTION 10.  THE ADMINISTRATIVE AGENT AND ISSUING BANKS.

    Section 10.1.  Appointment and Authorization. Each Lender hereby appoints
and authorizes the Administrative Agent to take such action as agent on its
behalf and to exercise such powers hereunder and under the Loan Documents as are
designated to the Administrative Agent by the terms hereof and thereof together
with such powers as are reasonably incidental thereto. The Lenders expressly
agree that the Administrative Agent is not acting as a fiduciary of the Lenders
in respect of the Loan Documents, the Company or otherwise, and nothing herein
or in any of the other Loan Documents shall result in any duties or obligations
on the Administrative Agent or any Lenders except as expressly set forth herein.
The Administrative Agent may resign at any time by sending 20 days prior written
notice to the Company and the Lenders and may be removed by the Required Lenders
upon 20 days prior written notice to the Company and the Lenders. In the event
of any such resignation or removal the Required Lenders may appoint a new agent,
which shall succeed to all the rights, powers and duties of the Administrative
Agent hereunder and under the Loan Documents, such new Administrative Agent to
be subject to the reasonable consent of the Company unless a Default or Event of
Default has occurred and is continuing. Any resigning or removed Administrative
Agent shall be entitled to the benefit of all the protective provisions hereof
with respect to its acts as an agent hereunder, but no successor Administrative
Agent shall in any event be liable or responsible for any actions 

                                     -46-
<PAGE>
 
of its predecessor. If the Administrative Agent resigns or is removed and no
successor is appointed, the rights and obligations of such Administrative Agent
shall be automatically assumed by the Required Lenders and (i) the Company shall
be directed to make all payments due each Lender hereunder directly to such
Lender and (ii) the Administrative Agent's rights in the Loan Documents shall be
assigned without representation, recourse or warranty to the Lenders as their
interests may appear.

     Section 10.2.  Rights as a Lender. The Administrative Agent has and
reserves all of the rights, powers and duties hereunder and under the other Loan
Documents as any Lender may have and may exercise the same as though it were not
the Administrative Agent and the terms "Lender" or "Lenders" as used herein and
in all of such documents shall, unless the context otherwise expressly
indicates, include the Administrative Agent in its individual capacity as a
Lender. The Administrative Agent reserves the right to engage in other business
transactions with the Company, the Subsidiaries and their Affiliates.

     Section 10.3.  Standard of Care.  The Lenders acknowledge that they have
received and approved copies of the Loan Documents, and such other information
and documents concerning the transactions contemplated and financed hereby as
they have requested to receive and/or review. The Administrative Agent makes no
representations or warranties of any kind or character to the Lenders with
respect to the validity, enforceability, genuineness, perfection, value, worth
or collectibility hereof or of the other Loan Documents or of the liens, if any,
provided for thereby or of any other documents called for hereby or thereby or
of the collateral, if any. The Administrative Agent need not verify the worth or
existence of any collateral, or any other Property, and may rely exclusively on
reports provided by the Company. The Lenders agree that neither the
Administrative Agent nor any director, officer employee, agent or representative
thereof (including any security trustee therefor) shall in any event be liable
for any clerical errors or errors in judgment, inadvertence or oversight, or for
action taken or omitted to be taken by it or them hereunder or under the Loan
Documents or in connection herewith or therewith except for its or their own
gross negligence or willful misconduct. The Administrative Agent shall incur no
liability under or in respect of this Agreement or the other Loan Documents by
acting upon any notice, certificate, warranty, instruction or statement (oral or
written) of anyone (including anyone in good faith believed by it to be
authorized to act on behalf of the Company), unless it has actual knowledge of
the untruthfulness of same. The Administrative Agent agrees to use the same care
in protecting the interests of the Lenders in the Loans as it uses for similar
loans or extensions of credit held by it solely for its own account. The
Administrative Agent shall be entitled to assume that no Default or Event of
Default exists, absent actual knowledge thereof, unless notified to the contrary
by a Lender. The Administrative Agent shall in all events be fully protected in
acting or failing to act in accord with the instructions of the Required
Lenders. Upon the occurrence of an Event of Default hereunder, the
Administrative Agent shall take such action with respect to the enforcement of
its rights and remedies hereunder and under any collateral and the preservation
and protection thereof as it shall be directed to take by the Required Lenders
(and shall consult with the Lenders as to actions to be taken) but unless and
until the Required Lenders have given such direction the Administrative Agent
shall take or refrain from taking such actions as it deems appropriate and in
the best of interest of all Lenders. The Administrative Agent shall in all cases
be fully justified in failing or refusing to act hereunder unless it shall be
indemnified to its reasonable satisfaction by the Lenders against any

                                     -47-
<PAGE>
 
and all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Administrative Agent may treat the owner
of any Note as the holder thereof until written notice of transfer shall have
been filed with it as provided in Section 12.12 hereof signed by such owner in
form satisfactory to the Administrative Agent. Each Lender acknowledges that it
has independently and without reliance on the Administrative Agent or any other
Lender and based upon such information, investigations and inquiries as it deems
appropriate made its own credit analysis and decision to extend credit to the
Company. It shall be the responsibility of each Lender to keep itself informed
as to the creditworthiness of the Company and each Subsidiary and the
Administrative Agent shall have no liability to any Lender with respect thereto.

     Section 10.4.  Costs and Expenses.  Each Lender agrees to reimburse the
Administrative Agent for all out-of-pocket costs and expenses suffered or
incurred by the Administrative Agent or any security trustee in performing its
duties hereunder and under the other Loan Documents or in the exercise of any
right or power imposed or conferred upon the Administrative Agent hereby or
thereby, to the extent that the Administrative Agent is not promptly reimbursed
for same by the Company or out of any collateral, all such costs and expenses to
be borne by the Lenders ratably in accordance with the amounts of their
respective Commitments.

     Section 10.5.  Indemnity.  The Lenders shall ratably indemnify and hold the
Administrative Agent, and each of its directors, officers, employees, agents or
representatives (including as such any security trustee therefor), harmless from
and against any liabilities, losses, costs or expenses suffered or incurred by
them under this Agreement or any of the other Loan Documents or in connection
with the transactions contemplated hereby or thereby, regardless of when
asserted or arising, except to the extent they are promptly reimbursed for the
same by the Company or out of any collateral and except to the extent that any
event giving rise to a claim was caused by the gross negligence or willful
misconduct of the party seeking to be indemnified.

     Section 10.6.  Designation of Additional Agent.  The Administrative Agent
shall have the continuing right, for purposes hereof, at any time or from time
to time to designate one or more Lenders (and/or its or their Affiliates) as
"Documentation Agents," "Lead Arrangers, Book Managers, Syndication Agents," and
"Arrangers" or otherwise for purposes hereto, but such designations shall have
no substantive effect, and such Lenders and their Affiliates shall have no
additional powers, duties, or responsibilities as a result thereof.

SECTION 11.  GUARANTY.

     Section 11.1.  The Guaranty.  To induce the Lenders to provide the credits
described herein and in consideration of benefits expected to accrue to the
Company by reason of the Commitments and for other good and valuable
consideration, receipt of which is hereby acknowledged, each Guarantor hereby
unconditionally and irrevocably guarantees jointly and severally to the
Administrative Agent, the Lenders, and each other holder of any of the Notes,
the due and punctual payment of all present and future indebtedness of the
Company evidenced by or arising out of the Loan Documents, including, but not
limited to, the due and punctual payment of principal of and interest on the
Notes and the due and punctual payment of all other Obligations now or hereafter
owed by the Company under the Loan Documents as and when the

                                     -48-
<PAGE>
 
same shall become due and payable, whether at stated maturity, by acceleration
or otherwise, according to the terms hereof and thereof (the "Guaranteed
Obligations"). In case of failure by the Company punctually to pay any
indebtedness or other obligations guaranteed hereby (after giving effect to any
applicable cure periods), each Guarantor hereby unconditionally agrees jointly
and severally to make such payment or to cause such payment to be made
punctually as and when the same shall become due and payable, whether at stated
maturity, by acceleration or otherwise, and as if such payment were made by the
Company.

   Section 11.2.  Guarantee Unconditional.  The obligations of each Guarantor as
a guarantor under this Section 11 shall be unconditional and absolute and,
without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by:

          (a) any extension, renewal, settlement, compromise, waiver or release
     in respect of any obligation of the Company or of any other guarantor under
     this Agreement or any other Loan Document or by operation of law or
     otherwise;

          (b) any modification or amendment of or supplement to this Agreement
     or any other Loan Document;

          (c) any change in the existence, structure or ownership of, or any
     insolvency, bankruptcy, reorganization or other similar proceeding
     affecting, the Company, any other guarantor, or any of their respective
     assets, or any resulting release or discharge of any obligation of the
     Company or of any other guarantor contained in any Loan Document;

          (d) the existence of any claim, set-off or other rights which the
     Company or any other guarantor may have at any time against the
     Administrative Agent, any Lender or any other Person, whether or not
     arising in connection herewith;

          (e) any failure to assert, or any assertion of, any claim or demand or
     any exercise of, or failure to exercise, any rights or remedies against the
     Company, any other guarantor or any other Person or Property;

          (f) any application of any sums by whomsoever paid or howsoever
     realized to any obligation of the Company, regardless of what obligations
     of the Company remain unpaid;

          (g) any invalidity or unenforceability relating to or against the
     Company or any other guarantor for any reason of this Agreement or of any
     other Loan Document or any provision of applicable law or regulation
     purporting to prohibit the payment by the Company or any other guarantor of
     the principal of or interest on any Note or any other amount payable under
     the Loan Documents; or

          (h) any other act or omission to act or delay of any kind by the
     Administrative Agent, any Lender or any other Person or any other
     circumstance whatsoever that might, but for the provisions of this
     paragraph, constitute a legal or equitable discharge of the obligations of
     any Guarantor under this Section 11.

                                     -49-
<PAGE>
 
     Section 11.3.  Discharge Only Upon Payment in Full; Reinstatement in
Certain Circumstances.  Each Guarantor's obligations under this Section 11 shall
remain in full force and effect until the Commitments are terminated, and the
principal of and interest on the Notes and all other amounts payable by the
Company under this Agreement and all other Loan Documents shall have been paid
in full.  If at any time any payment of the principal of or interest on any Note
or any other amount payable by the Company under the Loan Documents is rescinded
or must be otherwise restored or returned upon the insolvency, bankruptcy or
reorganization of the Company or of any guarantor, or otherwise, each
Guarantor's obligations under this Section 11 with respect to such payment shall
be reinstated at such time as though such payment had become due but had not
been made at such time.

     Section 11.4.  Subrogation.  Each Guarantor agrees it will not exercise any
rights which it may acquire by way of subrogation by any payment made hereunder,
or otherwise, until all the Guaranteed Obligations shall have been paid in full
subsequent to the termination of all the Commitments. If any amount shall be
paid to a Guarantor on account of such subrogation rights at any time prior to
the later of (x) the payment in full of the Guaranteed Obligations and all other
amounts payable by the Company hereunder and the other Loan Documents and (y)
the termination of the Commitments, such amount shall be held in trust for the
benefit of the Administrative Agent and the Lenders and shall forthwith be paid
to the Administrative Agent for the benefit of the Lenders or be credited and
applied upon the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of this Agreement.

     Section 11.5.  Waivers.  Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as
well as any requirement that at any time any action be taken by the
Administrative Agent, any Lender or any other Person against the Company,
another guarantor or any other Person.

     Section 11.6.  Limit on Recovery.  Notwithstanding any other provision
hereof, the right of recovery against any Guarantor under this Section 11 shall
not exceed $1.00 less than the lowest amount which would render such Guarantor's
obligations under this Section 11 void or voidable under applicable law,
including without limitation fraudulent conveyance law.

     Section 11.7.  Stay of Acceleration.  If acceleration of the time for
payment of any amount payable by the Company under this Agreement or any other
Loan Document is stayed upon the insolvency, bankruptcy or reorganization of the
Company, all such amounts otherwise subject to acceleration under the terms of
this Agreement or the other Loan Documents shall nonetheless be payable jointly
and severally by the Guarantors hereunder forthwith on demand by the
Administrative Agent made at the request of the Required Lenders.

SECTION 12. MISCELLANEOUS.

     Section 12.1.  Waiver of Rights.  No delay or failure on the part of any
Lender or the holder or holders of any Note in the exercise of any power or
right shall operate as a waiver thereof or as an acquiescence in any default,
nor shall any single or partial exercise thereof or the exercise of any other
power or right preclude any other right or the further exercise of any other
rights. The rights and remedies hereunder of the Company, the Administrative
Agent, the

                                     -50-
<PAGE>
 
Lenders and of the holder or holders of any Note are cumulative to, and not
exclusive of, any rights or remedies which any of them would otherwise have.

     Section 12.2.  Non-Business Day.  If any payment of principal shall fall
due on a day which is not a Business Day, interest at the rate such principal
bears for the period prior to maturity shall continue to accrue on such
principal from the stated due date thereof to and including the next succeeding
Business Day on which the same is payable.

     Section 12.3.  Documentary Taxes.  The Company agrees to pay any
documentary, stamp or similar taxes payable in respect to this Agreement or any
other Loan Document, including interest and penalties, in the event any such
taxes are assessed irrespective of when such assessment is made and whether or
not any credit is then in use or available hereunder.

     Section 12.4.  Survival of Representations.  All representations and
warranties made in the Loan Documents or pursuant thereto or in certificates
given pursuant hereto or thereto shall survive the execution and delivery of
this Agreement and of the other Loan Documents, and shall continue in full force
and effect with respect to the date as of which they were made as long as any
credit is in use or available hereunder.

     Section 12.5.  Set-off Sharing.  Each Lender agrees with each other Lender
a party hereto that in the event such Lender shall receive and retain any
payment, whether by set-off or application of deposit balances or otherwise, on
or in respect of any Note or other Obligation outstanding under this Agreement
in excess of its ratable share of payments on all Notes and other Obligations
then outstanding to the Lenders, then such Lender shall purchase for cash at
face value, but without recourse, ratably from each of the other Lenders such
amount of the Notes or other Obligations held by each such other Lender (or
interest therein) as shall be necessary to cause such Lender to share such
excess payment ratably with all the other Lenders; provided, however, that if
any such purchase is made by any Lender, and if such excess payment or part
thereof is thereafter recovered from such purchasing Lender, the related
purchases from the other Lenders shall be rescinded ratably and the purchase
price restored as to the portion of such excess payment so recovered, but
without interest.

     Section 12.6.  Notices.  Except as otherwise specified herein, all notices
hereunder and under the other Loan Documents shall be in writing (including,
without limitation, notice by telecopy) and shall be given to the relevant party
at its address or telecopier number set forth below, or such other address or
telecopier number as such party may hereafter specify by notice to the
Administrative Agent and the Company given by courier, by United States
certified or registered mail, by telecopy or by other telecommunication device
capable of creating a written record of such notice and its receipt. Notices

specified in this Section or on the signature pages hereof and a confirmation of
such telecopy has been received by the sender, (ii) if given by mail, 5 days
after such communication is deposited in the mail, certified or registered with
return receipt requested, addressed as aforesaid or (iii) if given by any other
means, when delivered at the addresses specified in this Section or on the

and 3 hereof shall be effective only upon receipt.

     Section 12.7.  Counterparts.  This Agreement may be executed in any number
of counterparts, and by the different parties on different counterparts, each of
which when executed shall be deemed an original, but all such counterparts taken
together shall constitute one and the same instrument.

     Section 12.8.  Successors and Assigns.  This Agreement shall be binding
upon the Company and its successors and assigns, and shall be binding upon and
inure to the benefit of the Administrative Agent, the Lead Arrangers, Book
Managers, and Syndication Agents, the Documentation Agent and the Lenders and
their respective successors and assigns permitted pursuant to Section 12.12
hereof, including any subsequent holder of any Note. The Company may not assign
its rights or obligations hereunder without the prior written consent of the
Lenders.

     Section 12.9.  Participants.  Each Lender shall have the right at its own
cost to grant participations (to be evidenced by one or more agreements or
certificates of participation) in the Loans made by such Lender at any time and
from time to time to one or more other financial institutions, provided that no
such participant shall have any rights under this Agreement or any other Loan
Document (the participant's rights against the Lender granting its participation
to be those set forth in the participation agreement between the participant and
such Lender); provided, further, that no Lender shall transfer or grant any
participation under which the participant shall have rights to approve any
amendment to or waiver of this Agreement or any other loan Document except to
the extent such amendment or waiver would extend the final scheduled maturity of
Loan or Note in which such participant is participating, or reduce the rate or
extend the time of payment of interest or fees thereon (except in connection
with a waiver of applicability of any post-default increase in interest rates)
or reduce the principal amount thereof, or increase the amount of the
participant's participation over the amount thereof then in effect (it being
understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Commitment or of a mandatory prepayment shall not constitute a
change in the terms of such participation, and that an increase in any
Commitment or Loan shall be permitted without the consent of any participant if
the participant's participation is not increased as a result thereof. 

                                     -52-
<PAGE>
 
Each such Lender selling a participation shall be entitled to the benefits of
Sections 2.3(d), 3 and 4.9 hereof to the extent such Lender would have been so
entitled had no such participation been sold.

     Section 12.10.  Costs and Expenses.  The Company agrees to pay within 10
days of demand all reasonable costs and expenses of the Administrative Agent,
Lead Arrangers, Book Managers, and Syndication Agents and Documentation Agent in
connection with the preparation, negotiation, syndication, and administration of
the Loan Documents, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent, in connection with the
preparation and execution of the Loan Documents, and any amendment, waiver or
consent related thereto, whether or not the transactions contemplated herein are
consummated. The Company further agrees to indemnify the Administrative Agent,
Lead Arrangers, Book Managers, and Syndication Agents, Documentation Agent, each
Lender, and their respective directors, officers and employees, against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all reasonable expenses of litigation or
preparation therefor, whether or not the indemnified Person is a party thereto,
or any settlement arrangement arising from or relating to any such litigation)
which any of them may pay or incur arising out of or relating to any Loan
Document or any of the transactions contemplated thereby or the direct or
indirect application or proposed application of the proceeds of any Loan, other
than those which arise from the gross negligence or willful misconduct of the
party claiming indemnification. The Company, upon demand by the Administrative
Agent, Lead Arrangers, Book Managers, and Syndication Agents, Documentation
Agent or a Lender at any time, shall reimburse the Agent, Lead Arrangers, Book
Managers, and Syndication Agents, Documentation Agent or such Lender for any
legal or other expenses incurred in connection with investigating or defending
against any of the foregoing (including any settlement costs relating to the
foregoing) except if the same is directly due to the gross negligence or willful
misconduct of the party to be indemnified. The obligations of the Company under
this Section shall survive the termination of this Agreement.

     Section 12.11.  Construction.  The parties hereto acknowledge and agree
that this Agreement shall not be construed more favorably in favor of one than
the other based upon which party drafted the same, it being acknowledged that
all parties hereto contributed substantially to the negotiation of this
Agreement.

     Section 12.12.  Assignments.  (a) Each Lender may, from time to time,
with the consent of the Administrative Agent and the Documentation Agent and, so
long as no Event of Default exists, the Company, which consent will
not be unreasonably withheld, assign to other financial institutions part of the
indebtedness evidenced by the Notes then owned by it together with an equivalent
proportion of its obligation to make Loans hereunder pursuant to written
agreements executed by the assignor, the assignees, the Administrative Agent,
the Documentation Agent and, so long as no Event of Default exists, the Company,
which agreements shall specify in each instance the portion of the indebtedness
evidenced by the Notes which is to be assigned to each such assignee and the
portion of the Commitment of the assignor to be assumed by it and shall be
substantially in the form attached hereto as Exhibit D (the "Assignment
Agreements"); provided, however, that (i) each such assignment shall be of a
constant, and not a varying, percentage of the assigning Lender's rights and
obligations under this Agreement and the assignment shall cover 

                                     -53-
<PAGE>
 
the same percentage of such Lender's Commitment, Loans and Note; (ii) unless the
Administrative Agent, the Documentation Agent and the Company otherwise consent,
the aggregate amount of the Commitment, Loans and Note of the assigning Lender
being assigned pursuant to each such Assignment Agreement (determined as of the
effective date of the relevant Assignment Agreement) shall in no event be less
than $2,000,000 and, unless the assigning Lender shall have assigned all of its
Commitment, Loans and Note, the aggregate amount of the Commitment, Loans, and
Note retained by the assigning Lender shall in no event be less than $2,000,000;
and (iii) the assigning Lender must pay to the Administrative Agent a processing
and recordation fee of $3,500 and any out-of-pocket attorney's fees and expenses
incurred by the Administrative Agent in connection with each such Assignment
Agreement. Upon the execution of each Assignment Agreement by the assignor, the
assignee, the Administrative Agent, the Documentation Agent and, if applicable,
the Company (i) such assignee shall thereupon become a "Lender" for all purposes
of this Agreement with a Commitment in the amount set forth in such Assignment
Agreement (and Exhibit A hereto shall be deemed amended to reflect the aggregate
Commitments of the Lenders after giving effect thereto) and with all the rights,
powers and obligations afforded a Lender hereunder, provided that the assigning
Lender shall retain the benefit of all indemnities of the Company with respect
to matters arising prior to the effective date of such Assignment Agreement,
which shall survive and inure to the benefit of the assigning Lender, (ii) such
assigning Lender shall have no further liability for funding the portion of its
Commitment assumed by such other Lender and (iii) the address for notices to
such Lender shall be as specified in the Assignment Agreement executed by it.
Concurrently with the execution and delivery of such Assignment Agreement by the
assignor, the assignee, the Administrative Agent, the Documentation Agent and,
if applicable, the Company shall execute and deliver a Note to the assignee
Lender in the amount of its Commitment and a new Note to such assigning Lender
in the amount of its Commitment after giving effect to the reduction occasioned
by such assignment, all such notes to constitute "Notes" for all purposes of
this Agreement.

     (b) Any Lender may at any time pledge or grant a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any such pledge or grant to a Federal Reserve Bank, and this
Section shall not apply to any such pledge or grant of a security interest;
provided that no such pledge or grant of a security interest shall release a
Lender from any of its obligations hereunder or substitute any such pledgee or
secured party for such Lender as a party hereto; provided further, however, the
right of any such pledgee or grantee (other than any Federal Reserve Bank) to
further transfer all or any portion of the rights pledged or granted to it,
whether by means of foreclosure or otherwise, shall be at all times subject to
the terms of this Agreement.

   Section 12.13. Amendments.  Any provision of this Agreement or the other
Loan Documents may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by (a) the Company, (b) the Required Lenders,
and (c) if the rights or duties of the Administration Agent or an Issuing Bank
are affected thereby, the Administration Agent or such Issuing Bank, as
applicable; provided that:

          (i)  no amendment or waiver pursuant to this Section 12.13 shall (A)
     increase any Commitment of any Lender without the consent of such Lender or
     (B) reduce the amount of or postpone the date for any scheduled payment of
     any principal of or interest

                                     -54-
<PAGE>
 
     on any Loan or of any fee payable hereunder without the consent of the
     Lender to which such payment is owing or which has committed to make such
     Loan hereunder; and

          (ii) no amendment or waiver pursuant to this Section 12.13 shall,
     unless signed by each Lender, increase the aggregate Commitments hereunder
     (exclusive of increases permitted by Section 4.10 hereof), change the
     definitions of Termination Date or Required Lenders, change the provisions
     of this Section 12.13, Section 7, or Section 9, release any Guarantor, or
     affect the number of Lenders required to take any action hereunder or under
     any other Loan Document;

it being understood that waivers or modifications of covenants, Defaults or
Events of Default (other than those set forth in Section 9.1(j) and (k) hereof)
or of a mandatory reduction in the Commitments or of a mandatory prepayment may
be made at the discretion of the Required Lenders and shall not constitute an
increase of the Commitment of any Lender, and that any resulting increase in the
available portion of any Commitment of any Lender shall not constitute an
increase in the Commitment of such Lender, and any waiver of applicability of
any post-default increase in interest rates may be made at the discretion of the
Required Lenders.

   Section 12.14.  Entire Agreement.  This Agreement and the Loan Documents
constitute the entire understanding of the parties with respect to the subject
matter hereof and any prior agreements, whether written or oral, with respect
thereto are superseded hereby.

   Section 12.15.  Headings.  Section headings used in this Agreement are for
reference only and shall not affect the construction of this Agreement.

   Section 12.16.  Confidentiality.  (a) Any information disclosed by the       
Company or any of its Subsidiaries to the Administrative Agent or any of the
Lenders shall be used solely for purposes of this Agreement and for the purpose
of determining whether or not to extend other credit or financial accommodations
to the Company or its Subsidiaries and, if such information is not otherwise in
the public domain, shall not be disclosed by the Administrative Agent or such
Lender to any other Person except (i) to its independent accountants and legal
counsel (it being understood that the Persons to whom such disclosure is made
will be informed of the confidential nature of such information and instructed
to keep such information confidential), (ii) pursuant to statutory and
regulatory requirements, (iii) pursuant to any mandatory court order, subpoena
or other legal process, (iv) to the Administrative Agent or any other Lender,
(v) pursuant to any agreement heretofore or hereafter made between such Lender
and the Company which permits such disclosure, (vi) in connection with the
exercise of any right or remedy under the Loan Documents, provided that such
Lender or the Administrative Agent, as applicable, shall give the Company prior
written notice of any such disclosure or (vii) subject to an agreement
containing provisions substantially the same as those of this Section, to any
participant in or assignee of, or prospective participant in or assignee of, any
obligation or Commitment.

     (b)  The Administrative Agent and the Lenders acknowledge that the Company
and its Subsidiaries perform classified contracts funded by and/or for the
benefit of the United States Government and, accordingly, neither the Company
nor any Subsidiary will be obligated to release, disclose or otherwise make
available to the Administrative Agent or any Lender any 

                                     -55-
<PAGE>
 
classified or special nuclear material to any parties not in possession of a
valid security clearance and authorized by the appropriate agency of the United
States Government to receive such material. The Administrative Agent and the
Lenders agree that in connection with any exercise of a right or remedy the
United States Government may remove classified information or government-issued
property prior to any remedial action implicating such classified information or
government-issued property. Upon notice from the Company, the Administrative
Agent and the Lenders shall take such steps in accordance with this Agreement as
may be reasonably requested by the Company to enable the Company or any
Subsidiary to comply with the Foreign Ownership Control or Influence
requirements of the United States Government imposed from time to time.

          Section 12.17.  Excess Interest.  Notwithstanding any provision to the
contrary contained herein or in any other Loan Document, no such provision shall
require the payment or permit the collection of any amount in excess of the
maximum amount of interest permitted by applicable law to be charged for the use
or detention, or the forbearance in the collection, of all or any portion of the
Loans or other Obligations outstanding under this Agreement or any other Loan
Document ("Excess Interest").  If any Excess Interest is provided for, or is
adjudicated to be provided for, herein or in any other Loan Document, then in
such event (a) the provisions of this Section shall govern and control; (b)
neither the Company nor any guarantor or endorser shall be obligated to pay any
Excess Interest; (c) any Excess Interest that the Administrative Agent or any
Lender may have received hereunder shall, at the option of the Administrative
Agent, be (i) applied as a credit against the then outstanding principal amount
of Loans hereunder, accrued and unpaid interest thereon (not to exceed the
maximum amount permitted by applicable law) and any other Obligations, or all of
the foregoing; (ii) refunded to the Company, or (iii) any combination of the
foregoing; (d) the interest rate payable hereunder or under any other Loan
Document shall be automatically subject to reduction to the maximum lawful
contract rate allowed under applicable usury laws, and this Agreement and the
other Loan Documents shall be deemed to have been, and shall be, reformed and
modified to reflect such reduction in the relevant interest rate; and (e)
neither the Company nor any guarantor or endorser shall have any action against
the Administrative Agent or any Lender for any damages whatsoever arising out of
the payment or collection of any Excess Interest.

          Section 12.18.  Lender's Obligations Several.  The obligations of the
Lenders hereunder are several and not joint.  Nothing contained in this
Agreement and no action taken by the Lenders pursuant hereto shall be deemed to
constitute the Lenders a partnership, association, joint venture or other
entity.

          Section 12.19.  Governing Law.  This Agreement and the Notes, and the
rights and duties of the parties hereto, shall be construed and determined in
accordance with the laws of the State of Illinois, without regard to principles
of conflicts of laws.

          Section 12.20.  Submission to Jurisdiction; Waiver of Jury Trial.
The Company and each Guarantor hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Northern District of Illinois and of
any Illinois State court sitting in the City of Chicago for purposes of all
legal proceedings arising out of or relating to this Agreement, the other Loan

                             AMENDED AND RESTATED
                             CONSORTIUM AGREEMENT


     THIS AMENDED AND RESTATED CONSORTIUM AGREEMENT (this "AGREEMENT"), dated as
of March 19, 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.
          
     4.   WGNH entered into 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

                                                                    CONFIDENTIAL

          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.

     NOW THEREFORE, in consideration of the premises and the mutual covenants
     and agreements contained in this Agreement, the Original Agreement,
     including the Exhibits thereto, is hereby amended and restated to read in
     its entirety as follows:

1.   FORMATION OF ADDITIONAL COMPANIES.

     1.1  Interim Companies. MK and BNSI have organized the following limited
          -----------------
          liability companies (sometimes referred to individually as an "INTERIM
          COMPANY" and collectively as the "INTERIM COMPANIES"):

          (a)  MK/BNFL GESCO LLC, a Delaware limited liability company ("INTERIM
               GESCO"), the membership interests in which are owned on a 60/40
               basis by MK and BNSI, respectively, as set forth in greater
               detail in a limited liability company agreement dated as of
               October 10, 1998.

          (b)  MK/BNFL Commercial Nuclear Services LLC, a Delaware limited
               liability company ("INTERIM CNS"), the membership interests in

               set forth in greater detail in a limited liability company
               agreement dated as of October 10, 1998.

          (c)  MK WGS LLC, a Delaware limited liability company ("INTERIM WGS"),
               the membership interests in which are wholly owned by MK, as set
               forth in greater detail in a limited liability company agreement
               dated as of December 30, 1998.

     1.2  Organization. Promptly after the date of this Agreement the parties
          ------------
          will organize the following corporations or limited liability
          companies (sometimes referred to individually as a "COMPANY" and
          collectively as the ("COMPANIES") under the names, to take effect from
          the closing of the Asset Purchase Agreements, set forth below and,
          prior to closing, under such other interim names as the parties may
          agree:

          (a)  Westinghouse Government Services Company LLC, a Delaware limited
               liability company ("WGS")

          (b)  Westinghouse Government Environmental Services Company LLC, a
               Delaware limited liability company ("WGES")

          (c)  Westinghouse Electric Company LLC, a Delaware limited liability
               company ("WELCO")

          (d)  Such other entities as the parties deem necessary or desirable to
               carry out the intent of this Agreement but not otherwise in
               contradiction of the terms of this Agreement.

          If appropriate, the parties may reorganize Interim GESCO as WGES,
          Interim CNS as WELCO, and Interim WGS as WGS in which case they will
          transfer their membership interests and make such other changes in the
          organizational documents of such companies as may be necessary to
          conform to the terms of this Agreement. If any of the Interim
          Companies is not reorganized as contemplated by the preceding sentence
          the parties will cause it to be dissolved.

     1.3  Operating Agreements. The ownership, management, operation, financing
          --------------------
          and other attributes of the Companies will be set forth in the
          respective articles of incorporation, by-laws, limited liability
          company agreements and related documents to be entered into with
          respect to each of the Companies and other necessary documents which
          will be consistent with the provisions of this Agreement.

          -------

                                                                 ------------
          and 6.3 and to execute and deliver any appropriate amendments to the
              ---

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

     9.7  Employees.
          ---------
 
          (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

                                     -19-
<PAGE>
 
                                                                    CONFIDENTIAL

            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,
            including know-how that is or has been used by the EMD in the
            manufacture of equipment in connection with the ESBU Business (the
            "SPECIFIED EMD KNOW-HOW"). Such requests shall be made by the
            applicable 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 and, in the case of the Specified EMD 
            Know-How, in accordance with the terms of a supplemental agreement
            between the parties and together with as much instruction and
            training as may reasonably be required to enable WELCO to understand
            and utilize such know-how. 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.
           
     10.6  Agreements. MK and BNFL-USA will cause their affiliates, including
           ----------
           the Companies, to enter into appropriate agreements to carry out the
           purpose of this Section 10.
                           ----------

           ----------
           
           (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
           ------------------------------                            ----------

           (b)   WGNH, WGS, WGES and WELCO, and their respective subsidiaries,
                 are referred to as "SECOND TIER ENTITIES".

                 ---
                 whatsoever (including liabilities existing on the GESCO Closing
                 Date) that arises from the business or operations of WGS, WGS

                 (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 BNFL-USA and MK will make
                 appropriate payments to each other and their respective
                 affiliates such that MK and its affiliates, on the one hand,
                 and BNFL-USA 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 basis.
                 
           (b)   WGES.  In the case of any liability of any kind or nature 
                 ----

                 harmless against any Losses, provided that there shall be
                 excluded from indemnification any Loss that is reflected in a
                 reduction in the value of any equity interest in WGES held by
                 MK or BNFL-USA, BNSI or their affiliates. If the assets of
                 WGES, 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 affiliates, on the one hand,
                 and BNFL-USA and its affiliates, on the other hand, (taking
                 into account their economic participation in the Second Tier
                 Entities) share any Losses on a 60/40 basis.
                 
           (c)   WELCO. In the case of any liability of any kind or nature
                 -----
                 whatsoever (including liabilities existing on the ESBU Closing
                 Date) that arises from the business or operations of WELCO,
                 WELCO will indemnify and defend MK-Delaware, MK, their
                 affiliates, WGNH and any other Second Tier Entities and their
                 affiliates and hold them harmless against any Losses. If the
                 assets of WELCO are insufficient to perform the required
                 indemnification
