MORRISON KNUDSEN CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands of dollars except per 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 December 3, 1999. The comparative consolidated balance sheet and
related disclosures at December 3, 1999 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 financial position, results of operations and cash
flows for the interim periods presented. The results of operations for the
quarter ended March 3, 2000 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 from those estimates. On an
ongoing basis, management reviews its estimates based on information that is
currently available. Changes in facts and circumstances may result in revised
estimates.

2.   ADOPTION OF ACCOUNTING PRINCIPLES

     On December 4, 1999, the Corporation adopted Statement of Position ("SOP")
98-5 Reporting on the Costs of Start-Up Activities. The SOP provides guidance on
the financial reporting of start-up costs and organization costs to be expensed
as incurred. The SOP also amends SOP 81-1 Accounting for Performance of
Construction/Production Contracts by requiring pre-contract costs to be expensed
as incurred. The adoption of SOP 98-5 had no material effect on the
Corporation's financial position or results of operations.

3.   VENTURES

     The Corporation's share of results of operations from construction joint
ventures and mining ventures presented below excludes any allocation of division
or group level indirect overhead cost. Such costs are included in cost of
revenue in the Corporation's consolidated statements of income.

Construction joint ventures:

     The Corporation participates in construction joint ventures, generally as
sponsor and manager of the projects, which are formed to bid, negotiate and
complete specific projects. The size, scope and duration of joint-venture
projects vary among periods.

4.   ACQUISITION OF GESCO BUSINESSES

     On March 22, 1999, the Corporation and BNFL Nuclear Services, Inc. ("BNFL")
acquired operations of the Government and Environmental Services Company ("GESCO
businesses") from CBS Corporation. The acquisition of the GESCO businesses is
being accounted for as a purchase business combination. The allocation of the
purchase price to the net assets acquired includes preliminary estimates of
certain employee benefit obligations based primarily on incomplete information
provided by CBS Corporation and the management of the

                                      I-7
<PAGE>

GESCO businesses. The information necessary to complete the allocation includes
detailed participant data, and agreement and settlement of assets to be
transferred by CBS Corporation to the benefit plans, both of which could have a
material effect on the purchase price allocation. Final allocation of the
purchase price relating to benefit plan assets and liabilities assumed in the
GESCO acquisition is expected to be completed by the Corporation's second
quarter ending June 2, 2000.

     The following unaudited pro forma information presents the consolidated
results of operations of the Corporation as if the GESCO acquisition had taken
place on December 1, 1998, after giving effect to certain adjustments, including
amortization of goodwill on a straight-line basis over twenty years,
depreciation expense, interest expense, amortization of new credit facility fees
and related tax effects. These pro forma results of operations have been
prepared for illustrative purposes only and do not purport to be indicative of
operating results that would have resulted had the GESCO acquisition occurred on
the dates indicated, or of future operating results.

5.   CREDIT FACILITIES

     The Corporation has uncollateralized revolving credit facilities providing
an aggregate borrowing capacity of $325,000. These facilities consist of a
$195,000 five-year facility, which provides for both revolving borrowings and
the issuance of letters of credit, and a $130,000 one-year facility, which
provides for revolving borrowings. The one-year facility may be extended in
one-year increments by mutual agreement of the banks and the Corporation or
converted, at the Corporation's option, to a term loan having a maturity of one
year after the then current expiration of such facility. On March 18, 2000, the
one-year facility was extended for an additional year. The facilities' covenants
require the maintenance of financial ratios, and place limitations on
guarantees, liens, investments, dividends and other matters. At March 3, 2000,
$40,000 and $45,000 were outstanding on the one-year and five-year facilities,
respectively.

6.   CONTINGENCIES AND COMMITMENTS

Summitville environmental matters:

     From July 1985 to June 1989, Industrial Constructors Corp. ("ICC"), a
subsidiary of the Corporation, performed certain contract mining and
construction services at the Summitville mine near Del Norte, Colorado. In 1996,
the Environmental Protection Agency (the "EPA") and the State of Colorado (the
"State") commenced an action under CERCLA in the United States District Court
for the District of Colorado against Mr. Robert Friedland, a potentially
responsible party, to recover the response costs incurred and to be incurred at
the Summitville Mine Superfund Site (the "Site"). No other parties were named as
defendants in the original complaints in this action. On April 30, 1999, Mr.
Friedland filed a third-party complaint naming ICC and nine other defendants,
alleging that such defendants are jointly and severally liable for such costs
and requesting that the same be equitably allocated. On October 1, 1999, the EPA
and the State filed amended complaints, naming ICC and six other parties as
defendants in addition to Mr. Friedland. On August 10, 1999, ICC filed an answer
to Mr. Friedland's third-party complaint and, on December 23, 1999, ICC filed
answers to the EPA's and the State's amended complaints, in each case denying
the allegations set forth in the complaints.

     The EPA and the State have estimated that the total response costs incurred
and to be incurred at the Site will approximate $150,000. ICC is not a party to
any agreement regarding the allocation of responsibility, and neither the EPA
nor the State have made an allocation of responsibility among the defendants.
ICC's share, if any, of the aggregate environmental liability associated with
the Site is not presently determinable and depends upon, among

                                      I-8
<PAGE>

other things, the manner in which liability may be allocated to or among ICC or
other defendants, the efficacy of any defenses that ICC or such other defendants
may have to any assertion of liability, the willingness and ability of such
other defendants to discharge such liability as may be allocated to them and the
outcome of any negotiations or settlement discussions between ICC and the EPA,
the State and/or such other defendants. Accordingly, no response costs have been
accrued at March 3, 2000.

     Management believes that ICC has sound factual and legal defenses to
liability in this matter. However, the ultimate resolution of this matter could
have a material adverse effect on ICC's financial position and could materially
and adversely affect its results of operations and cash flows in one or more
periods. Because ICC's financial position and results of operations are
consolidated with that of the Corporation, the ultimate resolution of this
matter could have a material adverse effect on the Corporation's financial
position and could materially and adversely affect 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 provision for loss due to uncertainties on
the project, including unpaid client-directed change orders and potential
project claims. Mediation of these change orders and claims has resulted in a
settlement with the client, and accordingly, the $3,900 provision was reversed
during the first quarter of 2000.

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 March 3,
2000 and December 3, 1999, $47,495 and $47,586, 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 with respect
to $3,000 in face amount of certain letters of credit that were outstanding at
March 3, 2000.

     In connection with a 1989 sale of Old MK's ownership interest in 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 $5,389 for the
bonds. Management believes a loss on the guarantee is not probable and,
accordingly, no accrual has been made.

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. 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. MK Gold is seeking recovery of alleged damages of
approximately $10,000. On January 5, 1999, the two cases were consolidated for
trial. The cases are scheduled for trial beginning April 2, 2001.

     Certain current and former officers, employees and directors of the
Corporation were named defendants in an action filed by two former participants
in the Old MK 401(k) plan and Employee Stock Ownership Plan in the United States
District Court for the District of Idaho. They seek to represent a purported
class of participants in those plans. The complaint alleges, among other things,
that the defendants breached certain fiduciary duties. On November 16, 1999, the
Court granted summary judgment as to all claims against all individual persons
named in the original complaint. An amended complaint added the Corporation and
additional officers and employees of the Corporation as defendants. Motions for
summary judgment are pending seeking dismissal of all remaining

                                      I-9
<PAGE>

claims against all remaining defendants, which are those defendants added in the
amended complaint along with two companies involved in administration of the
plans.

     Although the ultimate outcome of these matters discussed in the two
preceding paragraphs 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.

7.   SEGMENT INFORMATION

     The Corporation operates through three operating units, each of which
comprise a separate reportable business segment: Engineers & Constructors Group,
Government Services Group and Contractors Group. The reportable segments are
separately managed, serve different markets and customers, and differ in their
expertise, technology and resources to perform their services.

     The accounting policies of the segments are the same as those described in
the summary of significant accounting policies in the Corporation's Annual
Report on Form 10-K. The Corporation evaluates performance and allocates
resources based on segment operating income. Segment operating income is total
segment revenue reduced by segment cost of revenue and goodwill amortization
identifiable to the segment. Goodwill amortization related to the acquisition of
Old MK is not allocated to the segments. Corporate and other operating loss
consists principally of general and administrative expense.

8.   RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board issued Statement No.
133 Accounting for Derivative Instruments and Hedging Activities ("SFAS No.
133"). SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts and for hedging activities. The statement requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
Corporation is currently evaluating the effect SFAS No. 133 will have on future
results of operations and financial position. Implementation of SFAS No. 133 is
required commencing with the first quarter of 2001.

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101") which summarizes the SEC staff's
position on selected revenue recognition issues. The Corporation is currently
evaluating what effect, if any, SAB 101 may have on its existing revenue
recognition policies, principally with respect to performance-based incentives.
Implementation of SAB 101 is required commencing with the first quarter of 2001.

9.   SUBSEQUENT EVENTS

Acquisition of Raytheon Engineers & Constructors:

     On April 14, 2000, Raytheon Company and Raytheon Engineers & Constructors
International, Inc., a wholly-owned subsidiary of Raytheon Company ("RECI"), and
the Corporation entered into a Stock Purchase Agreement ("the Agreement")
pursuant to which the Corporation has agreed to purchase the capital stock of
the subsidiaries of RECI and certain other assets of RECI, and to assume certain
liabilities of RECI. RECI provides engineering, design, procurement,
construction, operation, maintenance and other services on a worldwide basis.
The purchase price will be calculated using selected balance sheet items of the
acquired business as of April 30, 2000 as specified in the Agreement. Subject to
post-closing adjustments as provided in the Agreement, the Corporation expects
to pay approximately $10,000 and assume net liabilities of approximately
$500,000. Closing is expected on or about May 31, 2000, subject to regulatory
approvals and other customary conditions.

                                      I-11

Acquisition financing:

     The Corporation has accepted a $1,275,000 financing commitment from Credit
Suisse First Boston and Bank of Montreal. Such financing is subject to customary
conditions. Proceeds from the financing are expected to be used to finance the
acquisition, to refinance the Corporation's existing credit facility, to fund
working capital requirements and for general corporate purposes.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q and other reports and statements filed by
Morrison Knudsen Corporation (the "Corporation") from time to time with the
Securities and Exchange Commission (collectively, "SEC Filings") contain or may
contain forward-looking statements. When used in SEC Filings, the words "may,"
"will," "anticipate," "believe," "estimate," "expect," "future," "intend,"
"plan," "could," "should," "potential" or "continue" or the negative or other
variations thereof, as well as other statements regarding matters that are not
historical fact, are or may constitute forward-looking statements. Such
forward-looking statements are necessarily based on various assumptions and
estimates and are inherently subject to various risks and uncertainties
including, in addition to any risks and uncertainties disclosed in the text
surrounding such statements or elsewhere in the SEC Filings, risks and
uncertainties relating to the possible invalidity of the underlying assumptions
and estimates and possible changes or developments in social, economic,
business, industry, market, legal and regulatory circumstances and conditions
and actions taken or omitted to be taken by third parties, including the
Corporation's customers, suppliers, business partners and competitors and
legislative, regulatory, judicial and other governmental authorities and
officials. Should the Corporation's assumptions or estimates prove to be
incorrect, or should one or more of these risks or uncertainties materialize,
actual amounts, results, events and circumstances may vary significantly from
those reflected in such forward-looking statements.

RECENT DEVELOPMENTS

     On April 14, 2000, Raytheon Company and Raytheon Engineers & Constructors
International, Inc., a wholly-owned subsidiary of Raytheon Company ("RECI" and,
together with Raytheon Company, the "Sellers"), and the Corporation entered into
a Stock Purchase Agreement ("the Agreement") pursuant to which the Corporation
has agreed to purchase the capital stock of the subsidiaries of RECI and certain
other assets of RECI, and to assume certain liabilities of RECI. The Sellers
will retain certain assets of RECI and its subsidiaries and will indemnify the
Corporation for certain liabilities of RECI and its subsidiaries. RECI provides
engineering, design, procurement, construction, operation, maintenance and other
services on a worldwide basis. RECI and its subsidiaries had revenues of $2.7
billion in 1999, including revenues attributable to four projects for which the
Sellers have agreed to retain financial responsibility. The Corporation will act
as a subcontractor to the Sellers to complete the four projects, will be
reimbursed its costs to complete the projects and will receive from the Sellers
an amount equal to one-half of any cost savings achieved by the Corporation
relative to the Sellers' estimates of the cost to complete the projects. The
Agreement is filed as an exhibit to this report and is incorporated herein by
this reference.

     The purchase price will be calculated using selected balance sheet items of
the acquired business as of April 30, 2000 as specified in the Agreement.
Subject to post-closing adjustments as provided in the Agreement, the
Corporation expects to pay approximately $10 million and assume net liabilities
of approximately $500 million. In general, if the net amount of cash advanced or
paid by the Sellers for the use or benefit of the acquired business between
April 30, 2000 and the closing of the acquisition is greater or less than the
amount of cash transferred by the acquired business for the use or benefit of
the Sellers during such period, the Corporation will pay the Sellers an amount
equal to such excess or the Sellers will pay the Corporation an amount equal to
such deficiency, as applicable. Closing is expected to occur on or about May 31,
2000, subject to regulatory approvals and other customary conditions. The
Corporation anticipates incurring one-time restructuring charges of
approximately $25 million in connection with the acquisition.

     The Corporation has accepted a $1.275 billion financing commitment from
Credit Suisse First Boston and Bank of Montreal. Such financing is subject to
customary conditions. Proceeds from the financing are expected to be used to
finance the acquisition, to refinance the Corporation's existing credit
facility, to fund working capital requirements and for general corporate
purposes.

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

Revenue and gross profit:

     Revenue and gross profit for the quarter ended March 3, 2000 were $572.8
million and $24.7 million, respectively, an increase of 36% and 19%,
respectively, compared to the quarter ended February 26, 1999. The increase in
revenue was principally due to the acquisition of the GESCO businesses from CBS
Corporation and the concurrent formation of Westinghouse Government Services
Group ("WGSG") in March 1999. The results of operations for WGSG are included in
the results of operations for the Corporation in 2000, but were absent in the
comparable period of 1999. Gross profit increased due to the favorable
performance of a number of Industrial/Process contracts in the Engineers &
Constructors Group. The Corporation's gross profit as a percent of revenue
declined to 4.3% for the quarter ended March 3, 2000 from 4.9% from the
comparable period in 1999. The decline in the gross profit percentage was a
result of additional revenue of the Government Services Group which includes
WGSG for the first quarter of 2000, but not for the first quarter of 1999, and
the fact that award and incentive fees of WGSG are typically earned later in the
fiscal year. Earnings of the Government Services Group were also impacted by a
strike at the Electro-Mechanical Division plant which ended near the end of the
first quarter of 2000.

     The diversification of the Corporation's business may cause gross margins
to vary between periods due to inherent risks and rewards on fixed-price
contracts causing unexpected gains and losses on contracts. Gross margins may
also vary between periods due to changes in the mix and timing of contracts
executed by the Corporation, which contain various risk and profit profiles and
are subject to uncertainties inherent in the estimation process.

     At March 3, 2000, backlog of $3,244 million was comprised of $1,402 million
(43%) from fee-type contracts and $1,842 million (57%) from fixed-price
contracts and the Corporation's share from mining ventures.

General and administrative expense:

     General and administrative expense of $5.4 million for the quarter ended
March 3, 2000 declined $2.6 million from the comparable period of 1999 primarily
due to $1.7 million of additional compensation expense incurred in 1999 related
to a key executive retirement and a key executive recruitment, and a reduction
in benefit expenses in 2000.

Goodwill amortization:

     Amortization of cost in excess of net assets acquired ("goodwill") for the
quarter ended March 3, 2000 increased $3.4 million from the comparable period of
1999 due to the amortization of goodwill arising from the GESCO acquisition.
Annual amortization of the GESCO goodwill is currently estimated at
approximately $15

                                      I-14
<PAGE>

million, subject to possible adjustments to the recorded amount of GESCO
goodwill related to the final allocation of the purchase price to the fair value
of the net assets acquired.

Investment income:

     Investment income for the first quarter of 2000 declined $.3 million from
the first quarter of 1999 as a result of there being less cash available for
investment in a corporate short-term asset management account due primarily to
working capital requirements and repayment of the Corporation's revolving credit
facilities.

Interest expense:

     Interest expense for the quarter ended March 3, 2000 increased $2.1 million
over the comparable period of 1999 as a result of amortization of prepaid bank
fees associated with the establishment of additional revolving credit facilities
and interest expense attributable to additional borrowings which were primarily
used to fund the GESCO acquisition in March 1999.

Other income, net:

     The Corporation recognized other income of $2.2 million during the quarter
ended February 26, 1999 relating to the favorable resolution of contingencies
arising from the sale of a former subsidiary of Old MK.

Income tax expense:

     The effective tax rate for the first quarter of 2000 was 38.9% compared to
41.5% in the first quarter of 1999. The reduction in the effective tax rates
resulted from the GESCO acquisition and the resulting (1) reduction of
non-deductible goodwill amortization of Old MK, (2) additional pretax income
resulting in a lower proportion of non-deductible expenses compared to pretax
income and (3) lower state tax expense caused by more favorable apportionment of
pretax income. In addition, the Corporation's non-taxable income increased in
2000 compared to 1999.

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

Engineers & Constructors Group:

     Revenue increased slightly to $175.4 million for the quarter ended March 3,
2000 compared to $173.1 in the first quarter of 1999 due to an increase in work
performed on Energy related contracts. The group's operating income increased to
$7.4 million from $4.0 million in the first quarter of 1999 due to the favorable
performance of a number of Industrial/Process related contracts. Group overhead
costs increased approximately $2 million in the first quarter of 2000 over the
comparable period of 1999 principally from increased bidding and business
development costs.

Government Services Group:

     The Government Services Group recognized revenue of $184.1 million for the
first quarter of 2000, an increase of $116.2 million from the first quarter of
1999. The increase was primarily due to revenue recognized by WGSG, the
government and environmental businesses which were acquired from CBS Corporation
in March 1999. Operating income declined to $3.5 million in the first quarter of
2000 from $5.0 million in the first quarter of 1999 due to $3.7 million of
goodwill amortization related to the GESCO acquisition in the first quarter of
2000 and the fact that award and incentive fees earned by WGSG are usually
earned later in the fiscal year. The earnings of the group were also affected by
a strike at the Electro-Mechanical Division plant which ended near the end of
the first quarter of 2000. Revenue and operating loss of WGSG for the first
quarter of 2000 was $114.0 million and $3.2 million, respectively.

Contractors Group:

     Revenue and operating income increased 18% and 3%, respectively, to $213.3
million and $10.7 million for the first quarter of 2000 compared to the first
quarter of 1999. Contractors Group revenue increased from an increase in volume
of Heavy Civil work performed principally on new marine, transportation and
water resource contracts. Operating income increased due to the increase in
volume and positive performance on a number of Heavy Civil projects, including a
settlement related to a fixed-price contract resulting in the reversal of a $3.9
million pretax provision for loss. This increase in operating income was
partially offset by lower operating income from Mining operations which declined
in the first quarter of 2000 compared to the first quarter of 1999, principally
due to the favorable resolution of royalty issues on certain mining properties
and issues of a mining venture in 1999.

Intersegment and other:

     Intersegment and other operating loss of $1.0 million during the quarter
ended March 3, 2000 consisted primarily of a small loss from the Corporation's
captive self-insurance subsidiary and goodwill amortization associated with the
acquisition of Old MK. Operating income of $.6 million for the quarter ended
February 26, 1999 primarily consisted of income from the captive self-insurance
subsidiary, income from miscellaneous non-core businesses and goodwill
amortization related to the acquisition of Old MK.

FINANCIAL CONDITION AND LIQUIDITY

     The Corporation has three principal sources of liquidity: (1) existing cash
and cash equivalents; (2) cash generated by its operations; and (3) revolving
loan borrowings under its 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.

- --------------------------------------------------------------------------------------
</TABLE>


     Cash and cash equivalents declined $4.5 million to $25.1 million at March
3, 2000 from $29.6 million at December 3, 1999. The decline reflects net cash
provided by operating activities of $20.8 million, offset by cash used in
investing and financing activities of $10.1 million and $15.3 million,
respectively. The Corporation's net cash from operating activities during the
first quarter of 2000 was $20.8 million, compared to a net use of cash by
operating activities of $31.4 million used in the first quarter of 1999
primarily as a result of significant additional construction joint-venture cash
requirements and other working capital requirements for construction and
engineering contracts. Cash provided or used by operating activities is affected
to a large degree by the mix, timing, state of completion and commercial terms
of the Corporation's contracts, which are reflected in changes in net operating
assets and liabilities.

     Net cash used in investing activities for the quarter ended March 3, 2000
included $8.1 million of net purchases of property and equipment and $1.6
million of net purchases of marketable securities. Cash used in financing
activities included $15.0 million of net repayments on revolving lines of credit
and $.3 million of distributions to minority interests from the operations of
WGSG.

     The Corporation anticipates capital expenditures during the remainder of
2000 of approximately $34 million principally for normal replacement of major
construction equipment and to meet near-term equipment requirements for new
work.

     In July 1999, the Corporation received authorization to repurchase, in open
market transactions, block trades or otherwise up to 2 million shares of the
Corporation's outstanding common stock. The Corporation also has authorization
to repurchase up to 2.765 million of its warrants to purchase common stock. As
of March 3, 2000, the Corporation had not repurchased any shares under the
authorizations. Subject to market conditions and other

                                      I-17
<PAGE>

factors, purchases of shares may be commenced, discontinued and resumed from
time to time without prior notice.

     The Corporation has uncollateralized revolving credit facilities providing
an aggregate borrowing capacity of $325 million. These facilities consist of a
$195 million five-year facility, which provides for both revolving borrowings
and the issuance of letters of credit, and a $130 million one-year facility,
which provides for revolving borrowings. The one-year facility may be extended
in one-year increments by mutual agreement of the banks and the Corporation or
converted, at the Corporation's option, into a term loan maturing one year after
the then current expiration date of such facility. On March 18, 2000, the
one-year facility was extended for an additional year. At March 3, 2000, $40,000
and $45,000 were outstanding on the one-year facility and five-year facilities,
respectively. Depending on conditions in capital markets and other factors, the
Corporation may, from time to time, consider the possible issuance of other
long-term debt or securities.

     The Corporation is subject to foreign currency translation and exchange
issues, primarily with regard to its mining venture, MIBRAG mbH, in Germany. At
March 3, 2000, the cumulative adjustments for translation losses net of related
income tax benefits was $13.1 million. The Corporation realized a pretax gain on
foreign currency exchange transactions of $21 thousand for the three months
ended March 3, 2000. The Corporation endeavors to enter into contracts with
foreign customers with repayment terms in U.S. currency in order to mitigate
foreign exchange risk.

     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 March 3, 2000 was $3,244 million,
compared with $3,328 million at December 3, 1999. New work awarded in the
quarter ended March 3, 2000 totaled $489 million compared with $781 million for
the quarter ended December 3, 1999.

ENVIRONMENTAL CONTINGENCY

     The United States Environmental Protection Agency and the State of Colorado
have filed complaints against a subsidiary of the Corporation and six other
parties to recover response costs incurred and to be incurred at the Summitville
Mine Superfund Site. See Note 6. "Contingencies and Commitments - Summitville
environmental matters" of Notes to Condensed Consolidated Financial Statements.

RECENTLY ISSUED ACCOUNTING STANDARDS

     The Financial Accounting Standards Board has issued Statement No. 133
Accounting for Derivative Instruments and Hedging Activities. The SEC issued
Staff Accounting Bulletin No. 101 on revenue recognition. See Note 8. "Recently
Issued Accounting Standards" of Notes to Condensed Consolidated Financial
Statements for a discussion of the impact, if any, that these standards are
expected to have on the Corporation's financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
(In thousands of dollars)

     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 of less than 10 years and an average maturity
of 3.5 years. These long-term instruments are held to fund potential workers
compensation, general liability and auto liability obligations of the
Corporation. The Corporation seeks to match the maturities of these instruments
as closely as possible with the related obligations and to hold these
instruments to maturity in order to minimize market risk exposure, but may, from
time to time, sell them in response to market rates, needs for liquidity or
changes in availability of and the yield on alternative investments. As of March
3, 2000, the Corporation had $3,250 of short-term investments classified as cash
equivalents and $42,589 in its long-term investment portfolio.

     The Corporation may, from time to time, effect borrowings under bank credit
facilities or otherwise for general corporate purposes, including working
capital requirements, capital expenditures and acquisitions. Borrowings under
the Corporation's bank credit facilities of $85,000 at March 3, 2000 bear
interest at the applicable LIBOR or base rate plus an additional margin and,
therefore, the Corporation is subject to fluctuations in interest rates.

itself and as agent for RECI, as the aggregate purchase price for the Purchased
Shares and Acquired RECI Assets, an amount equal to the Estimated Purchase Price
(as defined in Section 3.4); provided however that if the Estimated Purchase
                             -------- -------

the Estimated Purchase Price is less than zero. The Estimated Purchase Price is

Balance Sheet, the Cut-Off Date Balance Sheet and the Sellers' Proposed
Calculations except to the extent that they deviate from the requirements of
paragraphs (a), (b) and (c) above or reflect mathematical errors, and (iii) that
it is to use every reasonable effort to complete such assignment and deliver
copies of such opinion and, if required, a revised Audited April Balance Sheet
and Cut-Off Date Balance Sheet and revised calculations of Adjusted Net Working

determination of the Remaining Disputed Items by the Independent Accounting
Firm. The fees and expenses of the Independent Accounting Firm shall be paid
one-half by the Buyer and one-half by the Sellers.

Non-Current Assets are less than $10,800,000, (iii) increased by the amount, if
any, by which Adjusted Net Working Capital is greater than $200,000,000, and
(iv) reduced by the amount, if any, by which Adjusted Net Working Capital is
less than $200,000,000 (collectively, the "Adjustment"). If the Final Purchase
                                           ----------
Price exceeds the Estimated Purchase Price, the Buyer shall pay an amount equal
to such excess to the Sellers, and if the Final Purchase Price is less than the
Estimated Purchase Price, the Sellers shall pay an amount equal to such
deficiency to the

systems when the date changed from December 31, 1999 to January 1, 2000 or from
February 28, 2000 to February 29, 2000 and as of the date of this Agreement the
Sellers have no knowledge of any fact or circumstance that have caused the
Sellers to believe that the year 2000 problem will have a Material Adverse
Effect.

                  (b) Except as described on Schedule 5.26, as of the date of
                                             -------- ----

                                    ---------

                       Conduct of Business Pending Closing
                       -----------------------------------

         Each of the Sellers and the Buyer covenant and agree that, from and
after the date of this Agreement and until the Closing or termination of this
Agreement, except as otherwise specifically consented to or approved by the
other party hereto (which consents and approvals shall not be unreasonably
withheld), each of the Sellers and the Buyer
<PAGE>

                                      -39-


shall perform its respective covenants set forth below. With respect to any
covenant set forth below applicable to any RECI Company, RECI agrees to cause
such other RECI Company to comply with such covenant. The provisions of this
Article 7 are cumulative, and the Sellers' obligations under any particular
Section hereof shall be determined without reference to (x) the provisions of
any other Section hereof or (y) the reference to the conduct of the Purchased
Business in the ordinary course contained in Section 7.2.

         7.1.     Full Access.
                  ---- ------

                  (a) Subject to any existing confidentiality obligations of the

normal business hours and upon reasonable notice to all personnel, facilities,
properties, books, records, contracts, bids and documents of such RECI Company
relating to the Purchased Business, the assets and liabilities of the RECI
Subsidiaries, the Acquired RECI Assets and the Assumed RECI Liabilities
(including access to the outside accountants for the RECI Companies and the
audit work papers of such accountants), and such RECI Company shall furnish or
cause to be furnished to the Buyer and its authorized representatives all such
information with respect to the Purchased Business as the Buyer may reasonably
request. The Buyer agrees to utilize such access in a manner so as not to
unreasonably disrupt the Purchased Business. The Sellers agree that the
limitations imposed above by attorney-client privilege or attorney work product
doctrine will not prohibit the Buyer from having access to the Sellers'
applicable legal personnel to discuss their caseloads and to review
non-privileged documents concerning existing and potential claims.

                  (b) Notwithstanding any provision of this Agreement to the
contrary, the Buyer and its representatives shall not have any access at any
time prior to the Closing to any information regarding pending or proposed bids
for new contracts or any related information where the Buyer or an Affiliate of
the Buyer also has or intends to bid for such contract, except that the Sellers
shall, and shall cause each of the RECI Subsidiaries to, provide such
information to the Bid Reviewer (as defined in the letter agreement dated the
date of this Agreement (the "Fire Wall Letter"), between the Sellers and the
                             ---- ---- ------

Buyer with a list of Project-Specific Plans.

substantially in the same manner as operated, maintained and preserved since
January 1, 1999 and shall not modify or amend their accounting policies,
practices and procedures or the manner in which their books, records and

<PAGE>

                                      -40-

methods of management or operation. Nothing contained in Sections 7.3 through
7.11 shall limit the generality or effect of this Section 7.2.

         7.3.     No General Increases. No RECI Company shall increase in any
                  -- ------- ---------

individual merit or other increases made in accordance with past custom and
practices. No RECI Company will amend in any material respect any of the Assumed
Employee Benefit Plans except for any amendments that the RECI Companies

         of business of the RECI Companies and in accordance with the business
         practices of the Purchased Business as conducted since January 1, 1999,
<PAGE>

                                      -41-


                      (ii)  any of the foregoing constitutes or relates to a
         cost-reimbursable contract for E&C Services and is expected (based
         solely on the bid proposal prepared by the applicable RECI Company) to

                      (iv)  such contract, bid, subcontract, agreement,

         guarantee by a RECI Company, liquidated damages payable by a RECI
         Company of more than $50,000 per day, any equity or debt investment by
         a RECI Company or any of its Affiliates or is submitted to or entered
         into with another member of the Raytheon Group.

                  However, no consent will be required under this paragraph (b)

ordinary course of business of the RECI Companies and in accordance with the
business practices of the Purchased Business as conducted since January 1, 1999
or (ii) the Buyer (except in the case of Overlapping Bids) determines, in its

any contract, bid, subcontract or agreement for which the Buyer's consent is
required under clause (iv) of paragraph (b) above (with any such contract, bid,
subcontract or agreement referred to below as a "Nonconforming Bid"), the

party. Where the Buyer is acting through the Bid Reviewer, the Buyer's consent
under this Section 7.4(c) shall be deemed given if the Bid Reviewer fails to
respond within five business days following their receipt of a written request
for such consent. Where the Buyer is not acting through the Bid Reviewer, the
Buyer's consent under this Section 7.4(c) shall be deemed given if the Buyer
fails to respond within two business days following its receipt of a written
request for such consent. The RECI Companies will not be required to prepare or

in its normal course of business regarding approval of contracts and bids.

                  (d) The Buyer and the Sellers agree to immediately develop
procedures to streamline the bid approval process contemplated by paragraph (c)
above and, to the maximum extent practicable, to run through the Buyer's bid
approval process at the same time the RECI Companies are completing their
internal approval process.

                  (e) Without the express written consent of the Buyer, no RECI
Company shall amend or modify in writing in any material respect, expressly
waive in writing a material right under or terminate any contract, subcontract

Seller Liabilities, Retained Risk E&C Contracts, Retained RECI Assets and

interests may appear, and the Sellers shall assure that any consent required of
the insurer shall be granted to the Buyer upon Closing and through the
completion of all obligations under the policy, including those activities
regarding the handling, investigation, defense, and settlement of any claims.

reasonable efforts to resolve such objections, if any, as may be asserted with
respect to the transactions contemplated by this Agreement under any Antitrust

judgment, injunction or other order (whether temporary, preliminary or
permanent) that is in effect and that restricts, prevents or prohibits
consummation of the transactions contemplated by this Agreement, including,
without limitation, by pursuing all reasonable avenues of administrative and
judicial appeal. The commercially reasonable efforts on the part of the Buyer
will include complying with any request to sell or otherwise dispose of, or hold
separate (through the establishment of a trust or otherwise) particular assets
or categories of assets, or businesses of the Buyer or the Purchased Business or
any of their Affiliates or withdraw from doing business in a particular
jurisdiction or take any other action requested so long as such action would

of the date hereof, to be realized by the Buyer from the consummation of the
transactions contemplated by this Agreement.

         8.2.     Access to Books and Records.
                  ------ -- ----- --- -------

                  (a) Subject to any existing confidentiality obligations of the
Sellers, from and after the Closing Date, during normal business hours and upon
reasonable notice, the Sellers will permit the Buyer and its auditors, through
its authorized representatives, to have access to and examine and take copies of
all records, contracts, bids and documents of the Sellers relating to the
Purchased Business which are not delivered to the Buyer pursuant to this
Agreement (including, but not limited to, correspondence, memoranda, books of
account and the like) and relating to (i) events occurring prior to the Closing
and (ii) transactions or events occurring subsequent to the Closing which are
related to or arise out of transactions or events occurring prior to the
Closing. The foregoing access will include any access reasonably required to
monitor the Sellers' compliance with the terms of this Agreement.

                  (b) Subject to any existing confidentiality obligations of the

reasonable notice, the Buyer will permit the Sellers and their auditors, through
their authorized representatives, to have access to and examine and take copies
of all books, records, contracts, bids and documents of the Sellers and the RECI
Subsidiaries relating to the Purchased Business which are delivered to the Buyer
pursuant to this Agreement (including, but not limited to, correspondence,
memoranda, books of account and the like). The foregoing access will include any
access reasonably required to monitor the Buyer's compliance with the terms of
this Agreement.

                  (c) The Buyer and the Sellers will each direct its employees
to render any assistance which the other party may reasonably request in
examining or utilizing records referred to in this Section 8.2, provided that
each party shall be reimbursed by the other for any out-of-pocket expenses which
it may incur in rendering the services provided for in this Section 8.2. In
addition, to the extent that any records referred to in this Section 8.2
retained by the Sellers and any records referred to in this Section 8.2
transferred to the Buyer or belonging to the RECI Subsidiaries are located in
the same third-party storage facilities, the Buyer and the Sellers shall enter
into mutually acceptable arrangements regarding the sharing of costs, security
procedures and similar matters. In addition, to the extent that either the Buyer
or the Sellers concludes at any
<PAGE>

                                      -47-


time more than sixty (60) days after the Closing Date in its reasonable judgment
that its personnel have been devoting significantly more time providing the
services referred to in paragraph (a) or paragraph (b) above than the personnel
of the other party, the Buyer and the Sellers will agree on mutually acceptable
reimbursement provisions to reflect such disparity.

                  (d) The Buyer and each of the Sellers shall preserve and
protect, and the Buyer shall cause the RECI Subsidiaries to preserve and
protect, all books, records, contracts, bids and documents, files and data

the preparation of Tax Returns, for a period of ten (10) years after the Closing
Date, and (ii) other than those described in (i) above, for a period of six (6)
years after the Closing Date (or, in the case of Government Contracts and
Government Subcontracts, for a period of six (6) years following Contract
Completion with respect thereto).

                  (e) Neither the Buyer nor any of the Sellers shall destroy,
and the Buyer shall cause the RECI Subsidiaries not to destroy, any files or
records which are subject to this Section 8.2 (i) for the periods described in
clause (d) of this Section 8.2 and (ii) thereafter, without giving at least
thirty (30) days' notice to the other party. Upon receipt of such notice, such
other party may (i) cause to be delivered to it the records intended to be
destroyed, at such other party's expense or (ii) notify the first party that
such other party will pay the cost of storing and maintaining such books and
records (including any necessary costs of moving such books and records to a
location under control of such other party).

                  (f) Each of the Sellers and the Buyer will keep all
information of the other party referred to in this Section 8.2 confidential in
accordance with Article 12 hereof.

                  (g) In addition, as soon as practicable after the date of this
Agreement, the Sellers will use reasonable efforts to provide to the Buyer (i) a
list of all individuals formerly employed in connection with the Purchased
Business primarily at locations outside the United States and who terminated
employment within five years before the date hereof, showing their latest
position and the grounds for termination, and describing any known claims
against the Purchased Business by such former employees and (ii) with respect to
any such individuals who perform services primarily at locations outside the
United States, a description of the type of employment agreement applicable to
such employee, the actuarial value of accrued pension rights (whether or not
vested), termination notice period, special termination protection (if any), and
membership in any body of employee representation.

         8.3.     Nonassignable Contracts.
                  ------------- ---------

                  (a) To the extent that any contract, governmental license
(other than any corporate charter or foreign qualification or similar
authorization) or permit included in the Acquired RECI Assets may not be
transferred to the Buyer pursuant to this
<PAGE>

                                      -48-


Agreement without the consent, approval or waiver of a third person or entity
(including a governmental authority), and such consent, approval or waiver is
not obtained prior to the Closing, or if such transfer or attempted transfer
would constitute a breach thereof or a violation of any law, rule or regulation,
nothing in this Agreement (or, except as expressly provided to the contrary
therein, in any document or instrument delivered at the Closing pursuant to
Section 4.2 hereof) will constitute a transfer or an attempted transfer thereof.

                  (b) Notwithstanding anything contained in this Agreement to
the contrary, RECI will not be obligated to transfer to the Buyer any of its
rights and obligations in, to or under any of the contracts, governmental
licenses or permits referred to in paragraph (a) above and the Buyer will not be
obligated to assume any obligations under any such contract, government license
or permit, unless and until all consents, approvals and waivers necessary for
such transfer and assumption shall have been obtained. RECI will use
commercially reasonable efforts, and the Buyer will cooperate with RECI and use
its commercially reasonable efforts, to obtain such consents, approvals and
waivers as promptly as practicable. Each of the Buyer and RECI shall bear its
own expenses incurred in connection with such efforts.

                  (c) In the event that any consent, approval or waiver
necessary to assign to the Buyer any such contract, governmental license or
permit is not obtained by RECI prior to the Closing, then the Sellers and the
Buyer will each use its commercially reasonable efforts, each at its own
expense, to (i) provide to the Buyer the benefits and burdens of any such
contract, governmental license or permit, (ii) cooperate in any reasonable and
lawful arrangement designed to provide such benefits and burdens to the Buyer in
accordance with this Agreement, without incurring any additional obligation to
any other person or entity, including without limitation the appointment of the
Buyer as RECI's agent for purposes of such contract, governmental license or
permit and (iii) enforce, at the request of the Buyer for the account of the
Buyer any rights of RECI arising from any such contract, governmental license or
permit (including without limitation the right to elect to terminate such
contract in accordance with the terms thereof upon the advice of the Buyer).
Following the Closing, the Sellers shall not terminate, modify, amend or take
any action that would result in a breach of any contract, governmental license
or permit referred to in paragraph (a) without the Buyer's prior written consent
(which the Buyer may grant or withhold in its sole and absolute discretion).

                  (d) No consent, approval or waiver of a third person or entity
(including a governmental authority) with respect to the transfer of, or any
novation with respect to, any contract (including any Government Contract or
Government Subcontract), shall cause a Specified Seller Liability to be deemed
for purposes of this Agreement to have become a Specified Buyer Liability or
vice-versa or otherwise affect the respective rights of the Buyer and the
Sellers under Article 13.

         8.4.     Retained Risk E&C Contracts.
                  -------- ---- --- ---------

                  (a) With respect to the Retained Risk E&C Contracts (other
than the Indemnified Project Agreements), at the request of the Sellers the
Buyer agrees to perform, or cause the RECI Subsidiaries to perform, all warranty
and other obligations thereunder that do not constitute Specified Buyer
Liabilities in accordance with the requirements of such contracts and in a
commercially reasonable manner consistent with the Buyer's ordinary business
practices. The Sellers shall compensate the Buyer and the RECI Subsidiaries for
their services pursuant to this paragraph (a) (i) for the first 5,000 hours of
service provided by the Buyer and the RECI Subsidiaries pursuant to this
paragraph (a), at the Buyer Labor Rate (as defined in Article 14) for all
personnel of the Buyer and its Affiliates who would be chargeable to contracts
for E&C Services under the normal charging policies of the Buyer and its
Affiliates and (ii) for services in excess of 5,000 hours, at rates based on
market rates provided for similar services provided by third parties, as agreed
from time to time by the Buyer and the Sellers. The Sellers also shall reimburse
the Buyer and the RECI Subsidiaries for out-of-pocket expenses and a reasonable
charge for use of any of their equipment. All such amounts shall be paid within
five (5) business days after submissions of invoices in reasonable detail on a
monthly basis. The payment by the Sellers of any such amounts as provided above
shall not prejudice their rights to subsequently contest the amounts set forth
in the applicable invoice. The Sellers' obligations with respect to Retained
Risk E&C Contracts under Section 13.1 shall not be limited by, nor duplicative
of, the Sellers' obligations under this Section 8.4.

                  (b) The Buyer agrees to cause the RECI Subsidiaries to grant
to the Sellers a non-exclusive non-transferable royalty-free license to use all
Intellectual Property of the RECI Subsidiaries or included in the Acquired RECI
Assets as required by the Sellers to complete any obligations under the Retained
Risk E&C Contracts, fulfill their obligations under this Agreement and the other
Acquisition Agreements and otherwise wind down their ownership of the Purchased
Business.

         8.5.     General Assistance.
                  ------- ----------

                  (a) The Buyer agrees to provide, or cause the RECI
Subsidiaries to provide, such support (including the availability of personnel
and records) as the Sellers may reasonably request to assist the Sellers in (i)
defending any litigation, arbitration or other dispute-resolution proceeding
relating to any casualty, personal injury, property damage, EEOC or other claims
of third parties relating to the Specified Seller Liabilities, or (ii) pursuing
claims of the Sellers against any third party, including insurers, and relating
to the Purchased Business, the RECI Companies, the assets of any RECI Subsidiary
or the Acquired RECI Assets. Without limiting the generality of the foregoing,
it shall constitute a reasonable request for assistance for the Sellers to
request that the Buyer use commercially reasonable efforts to provide witnesses
for interview and the giving of sworn testimony, including preparation of the
witness to testify, in connection with any trial, deposition, hearing or other
legal proceeding, arbitration or alternative dispute resolution proceeding. The
Sellers shall continue to direct all such
<PAGE>

                                      -50-


litigation and shall be responsible for all costs (including legal fees and
expenses incurred in connection therewith). The Sellers agree to pay all
out-of-pocket expenses incurred by the Buyer in providing such support. In
addition, after the Buyer or its Affiliates have expended in the aggregate a
total of 1,000 man-hours providing assistance pursuant to this Section 8.5, for
all additional services provided by the Buyer or its Affiliates pursuant to this
Section 8.5, the Sellers agree to pay the personnel costs for the services so
provided at the Buyer Labor Rate with respect to all personnel of the Buyer and
its Affiliates who would be chargeable to contracts for E&C Services under the
normal charging policies of the Buyer and its Affiliates. All such amounts shall
be paid in all cases within five (5) business days after submissions of invoices
in reasonable detail on a monthly basis. The payment by the Sellers of any such
amounts as provided above shall not prejudice their rights to subsequently
contest the amounts set forth in the applicable invoice. The Buyer agrees to use
commercially reasonable efforts to obtain from any Assumed Employee who
subsequently leaves pursuant to a severance arrangement undertakings of the sort
provided by the Buyer in the second sentence of this paragraph (a) and to use
commercially reasonable efforts to obtain such undertakings from any Assumed
Employee who leaves outside of a severance arrangement.

                  (b) Each of the Sellers agrees to use its commercially
reasonable efforts to provide such support (including the availability of
personnel and records) as the Buyer may reasonably request to assist the Buyer
and the RECI Subsidiaries in (i) defending any litigation, arbitration or other
dispute-resolution proceeding relating to any casualty, personal injury,
property damage, EEOC or other claims of third parties against the Buyer or the
RECI Subsidiaries relating to the Purchased Business (other than Specified
Seller Liabilities) or (ii) pursuing claims against any third party, including
insurers, and relating to the Purchased Business, the RECI Companies, the assets
of any RECI Subsidiary or the Acquired RECI Assets. Without limiting the
generality of the foregoing, it shall constitute a reasonable request for
assistance for the Buyer to request that the Sellers use commercially reasonable
efforts to provide witnesses for interview and the giving of sworn testimony,
including preparation of the witness to testify, in connection with any trial,
deposition, hearing or other legal proceeding, arbitration or alternative
dispute resolution proceeding. The Buyer and the RECI Subsidiaries shall direct
all such litigation and shall be responsible for all costs (including legal fees
and expenses incurred in connection therewith). In addition, after the Sellers
and their Affiliates have expended in the aggregate a total of 1,000 man-hours
providing assistance pursuant to this Section 8.5, the Buyer agrees to pay the
personnel costs of each of the Sellers or its Affiliates at the Buyer Labor
Rate, with respect to all personnel of the Sellers or their Affiliates who would
be chargeable to contracts for E&C Services under the normal charging policies
of the Sellers and their Affiliates, and out-of-pocket expenses incurred by the
Sellers in connection with providing such support, in all cases within five (5)
business days after submissions of invoices in reasonable detail on a monthly
basis. The payment by the Buyer of any such amounts as provided above shall not
prejudice its rights to subsequently contest the amounts set forth in the
applicable invoice.

         8.6. Collection Assistance; RR Assets. (a) The Sellers and the Buyer
              ---------- ----------  -- ------
acknowledge that, although the RECI Subsidiaries retain legal title to the
claims listed on Schedule 8.6 (the "Retained Claims"), they have agreed that as
                 -------- ---       -------- ------
between them the Sellers will be entitled to any amounts received with respect
to the Retained Claims except as provided in paragraph (b) below. The Buyer
agrees to use, or to cause the RECI Subsidiaries to use, such commercially
reasonable efforts (including commercially reasonable efforts to use
appropriately qualified personnel) in a manner consistent with the Buyer's
ordinary business practice of the Buyer and its Subsidiaries to collect for the
account of the Sellers any Retained Claims. This support will include causing
the RECI Subsidiaries to permit the Sellers (on terms reasonably acceptable to
the Buyer) to pursue these amounts as agent of the RECI Subsidiaries and the
Buyer and may include, when requested by the Sellers, taking a leading role on
behalf of the Sellers in actively pursuing collection. As part of these
commercially reasonable efforts, the Buyer will permit the Sellers adequate and
timely access (which may be by telephone) to any Assumed Employees that formerly
worked on such Retained Claims. The Sellers agree to pay 75% of the Buyer's
out-of-pocket expenses incurred in connection with the services so provided. All
such amounts shall be paid in all cases within five (5) business days after
submissions of invoices in reasonable detail on a monthly basis. The payment by
the Sellers of any such amounts as provided above shall not prejudice their
rights to subsequently contest the amounts set forth in the applicable invoice.
The Sellers shall not be required to reimburse the Buyer or RECI Subsidiaries
for personnel costs incurred in connection with the services contemplated by
this paragraph (a).

                  (b) The Buyer agrees that in the event it or any RECI
Subsidiary receives any payments on the Retained Claims, it will transfer or
cause the transfer of such amount less the MK Retained Amount (as defined below)
                                           -- -------- ------
to RECI within five (5) business days of receipt and until such transfer it will
hold such funds (less the MK Retained Amount) in trust for the benefit of the
Sellers. The "MK Retained Amount" shall mean the first $30,000,000 in payments
received on the Retained Claims and thereafter 25% of all payments on the
Retained Claims that the Buyer or any RECI Subsidiary receives. The Buyer will
provide such information relating to collections on the Retained Claims as the
Sellers may reasonably request from time to time, and will in any event deliver
to the Sellers, at least once per month, a reasonably detailed report of
collections. The Buyer will also meet from time to time with the Sellers as

Schedule 8.8 sets forth a correct and complete list of all bonds, letters of
- -------- ---
credit, guaranties and similar credit supports outstanding as of the date of
this Agreement in connection with the Transferred Risk E&C Contracts (together
with any guarantee entered into or letter of credit or surety bond obtained,
relating to a Transferred Risk E&C Contract, after the date of this Agreement
not in violation of Section 7.4, the "Support Agreements"). The Buyer agrees,
                                      ------- ----------
from and after the Closing, to use commercially reasonable efforts, which will
not include the payment of any consent fee or similar amount, but which will
include commercially reasonable efforts to provide substitute security of like
character, quality and amount, to provide substitute arrangements for, and to
obtain the release of the Sellers from, those Support Agreements indicated as
"To Be Released" on Schedule 8.8 and those entered into or obtained after the
                    -------- ---
date of this Agreement not in violation of Section 7.4. The Buyer will consult
with the Sellers from time to time concerning the progress made with respect to
any such releases, and will permit the Sellers reasonable participation in such
process. The Support Agreements to be retained by the Sellers are referred to
herein as the "Retained Support Agreements" and the Support Agreements to be
               -------- ------- ----------
released are referred to as the "Transferred Support Agreements".
                                 ----------- ------- ----------

                  (b) The Sellers shall cause each of the Support Agreements to
remain in effect in accordance with its terms until its scheduled expiration or,

                  (c) With respect to all the Retained Support Agreements and
all the Transferred Support Agreements not released as provided above, the Buyer
will reimburse the Sellers and their Affiliates for all premiums, payments and
other carrying costs of such Support Agreements, promptly after receipt of
invoices therefor. In the event the Sellers or their Affiliates are required to
reimburse a letter of credit issuer for any drawing under a Support Agreement,
or are required to make any payment under a Support Agreement that is a guaranty
or surety bond (other than carrying costs as provided above), then the Buyer
will reimburse the Sellers or such Affiliate within three (3) days after demand
for the payment of such amount. The Buyer's reimbursement obligation under this
Section 8.8 shall not be subject to any right of set-off or defense to payment
otherwise available to the Buyer. However, the payment by the Buyer of any such
reimbursement obligation will not constitute a waiver by the Buyer of any of its
rights to make a subsequent claim under Section 13.1, to the extent applicable.

                  (d) Promptly after the Buyer has provided substitute surety
bonds or other substitute security for the Pine Bluff project and the Buyer has
been released from the Transferred Support Agreements for the Pine Bluff project
pursuant to Section 8.8(a), the Sellers shall pay the Buyer the sum of
$1,000,000.

                  ----- --- -------- -----
Sellers and the Buyer agree to cooperate with respect to any sales and transfer
taxes payable with respect to the consummation of the transactions contemplated
by this Agreement. In connection with the foregoing, at or after the Closing the
Sellers and the Buyer shall prepare and deliver any applicable sales/use tax
resale certificates or other certificates required to be delivered in connection
with any available exemption from sales or use taxes and otherwise shall use
reasonable efforts to minimize the amount of all such sales and transfer taxes.

8.10, the Buyer agrees that immediately after the Closing Date, it will not use
and will cause the RECI Subsidiaries to cease using any reference to the
Raytheon name or the name "Raytheon Engineers & Constructors" or any variations
thereof, except that the Buyer and the RECI Subsidiaries may use up existing
stocks of printed materials, including, but not limited to, stationery,
promotional materials, drawings, and the like, so long as they are marked or
stickered so as to clearly indicate in a manner approved in writing by Raytheon
that the Purchased Business and RECI Subsidiaries are no longer affiliated with
Raytheon.

                  (b) In addition to the rights granted under paragraph (a)
above, the Sellers agree that during the two (2) year period after the Closing

manner) available to the public or any third party, including, but not limited
to, press releases, advertisements and other promotional materials, letterhead,
proposals, contracts, drawings and the like, must contain, in each and every
instance, a statement in a form approved in writing by Raytheon clearly
indicating that neither the Purchased Business, the RECI Subsidiaries nor the
Buyer are affiliated with Raytheon.

                  (c) Buyer shall indemnify Raytheon and its Affiliates as
provided in Section 13.2(v) in connection with Buyer's use of the Raytheon mark
and/or from the use of the name "Raytheon Engineers & Constructors" or any
variation thereof whether alone or in combination with other words or designs.

                  (d) Except for such permitted uses authorized above in this
Section 8.10, and notwithstanding anything contained herein to the contrary, no
rights or licenses are granted to the Buyer with respect to the Raytheon mark or
the name "Raytheon Engineers & Constructors" or any variation thereof whether
alone or in combination with other words or designs, and the Buyer agrees that
any license, whether express or implied, the RECI Subsidiaries may have been
granted with respect to the use of the Raytheon name, whether alone or in
combination with other words or designs, is hereby terminated effective as of
the Closing. Except as provided in paragraphs (a) and (b) above, the Buyer
agrees to cause each of the RECI Subsidiaries to amend its corporate name and
its charter documents as promptly as practicable after the Closing to delete any
use of the word "Raytheon". Prior to the Closing, the Sellers will cause the
RECI Subsidiaries to terminate any license, express or implied, that they may
have been granted with respect to the Raytheon name and to enter into an
agreement binding the REC Subsidiaries to the obligations set forth in paragraph
(e) below.

                  (e) The Buyer acknowledges that (i) Raytheon is, as between
the Buyer and any RECI Company on the one hand and Raytheon on the other hand,
the owner of all right, title and interest in and to the Raytheon mark, whether
alone or in combination with other words or designs and the Buyer shall not use
the Raytheon mark or permit any of the RECI Subsidiaries to use the Raytheon
mark except as expressly authorized by this Agreement and (ii) after the
Closing, it will not and will not permit the RECI Subsidiaries to (a) take any
action which would interfere with Raytheon's registration and/or use of the
Raytheon mark throughout the world; (b) take any action which would diminish or
dilute the distinctiveness or validity of the Raytheon mark; (c) challenge
Raytheon's ownership of the Raytheon mark and/or registration thereof; or (d)
attempt to register the Raytheon mark or any mark confusingly similar thereto,
alone or in combination with other words or designs, as a trademark, service
mark or trade name in its own name anywhere in the world. After the Closing, the
Buyer shall (at Sellers' expense) provide reasonable assistance to Raytheon in
connection with steps taken by Raytheon to protect the Raytheon mark, including,
but not limited to signing any registered user document or other documents
required by any Trademark Office or other Government Authority.

into bank accounts controlled by the Sellers, which relate to both the Purchased
Business and other businesses of the Sellers, the Sellers will take all steps
required so that at and after the Closing the Buyer has access to the cash

                  (b) In the event any Seller receives any cash after the
Closing to which the Buyer is otherwise entitled under this Agreement, it will
promptly remit such cash to the Buyer. In the event the Buyer or any RECI

construction business, such as providing technical services (which may include
engineering) in the form of seismic data analysis for a petroleum producer, or
designing a product, such as a photovoltaic cell, to be used by a power
producer.

                  (c) In addition to the foregoing, at no time after the Closing
will the Sellers or any Subsidiary represent to any Person that the Sellers
still own or operate the Purchased Business or are the successors in interest of
or otherwise operating the Purchased Business.

                  (d) The parties hereto acknowledge that any breach of the
covenants contained in this Section 8.15 will result in irreparable damage to
the Buyer for which the Buyer will have no adequate remedy at law and,
accordingly, that the Buyer shall be entitled to an injunction restraining the
Sellers from such breach; provided, however, that resort to such injunctive
                          --------  -------
relief shall not be exclusive of any other remedy at law, in equity or
otherwise, and shall not preclude the recovery of the Buyer of monetary damages
or other relief in addition thereto. If any of the restrictions contained in
this Section 8.15 shall be deemed by a court of competent jurisdiction to be
unenforceable by reason of the extent, duration or geographical or other scope
hereof, then such restrictions will be interpreted to apply only to the maximum
extent, duration, geographical or other scope that such court would find to be
enforceable.

         8.16.    Information Technology Transition. The Sellers and the Buyer
                  ----------- ---------- ----------
agree that they will take the steps required, if any, to obtain consents from
software vendors or obtain new software licenses so that the Buyer and RECI
Subsidiaries will have access to the software and information technology
described in Schedule 8.16(a). The costs of obtaining such consents or licenses
             -------- -------
will be borne by the Buyer. With respect to the software listed on

         8.17.    General Transitional Assistance. The Sellers agree to provide
                  ------- ------------ ----------
general transition assistance to Buyer and the RECI Subsidiaries after the
Closing in the areas described on Schedule 8.17(a) and other transitional
                                  -------- -------
business services similar to the ongoing business services provided to the
Purchased Business at the time of the Closing. These services will also include
the right to use any internet protocol address space or any proprietary software
systems held by Raytheon or any of its Subsidiaries, subject to any appropriate
confidentiality and security procedures. The Sellers will not be required to
provide any assistance to the extent not permitted by applicable law or the
Sellers' other contractual arrangements. Any such transitional assistance will
be at the request of Buyer. Buyer will reimburse the Sellers for any
out-of-pocket costs and an allocable portion of wages or salaries and related
costs and overhead of any Seller employees providing this assistance. Unless it
otherwise agrees, the Sellers will not be required to provide this assistance
for more than 365 days after Closing. The Sellers' only obligation is to provide
these services as provided in this Section 8.17 and they shall not be
responsible to the Buyer or the RECI Subsidiaries for any Losses (as defined in
Article 13) arising out of the provision of such services other than any Losses
that result from the Sellers' gross negligence or willful misconduct.

         8.18.    Foreign RECI Subsidiaries. In the event any foreign govern-
                  ------- ---- ------------
mental approvals required for the transfer of the RECI Subsidiaries are not
obtained by the Closing, then the Sellers and the Buyer shall consummate the
transactions contemplated by this Agreement without the transfers of any such
RECI Subsidiaries (the "Deferred Conveyance Subsidiaries").
                        -------- ---------- ------------

                  (a) The transfer of any Deferred Conveyance Subsidiary shall
be consummated within ten days following the procurement of such governmental
approvals as are applicable thereto. The Sellers and the Buyers shall work
diligently to cause all governmental approvals with respect to the Deferred
Conveyance Subsidiaries to be procured as promptly as practicable after the
Closing.

                  (b) To the maximum extent permitted under applicable law, the
economic interest in any Deferred Conveyance Subsidiary shall be deemed to have
transferred from Sellers to the Buyer effective as of the Closing Date. During
the period from the Closing Date to the consummation of the transfer of a
Deferred Conveyance Subsidiary (the "Interim Ownership Period"), the Sellers
                                     ------- --------- ------
shall hold the ownership interests of such Deferred Conveyance Subsidiary in the
manner provided in this Section 8.18 (such actions being "Deferred Operation
                                                          -------- ---------
Services"), with all gains, income, expense, profits and losses generated
- --------
thereby during such Interim Ownership Period being for the account of the Buyer.
Promptly following the conclusion of each Interim Ownership Period, the Sellers
and the Buyer shall jointly prepare and agree upon an accounting with respect to
the net cash transferred by RECI to such Deferred Conveyance Subsidiary or
received by RECI from such Deferred Conveyance Subsidiary and shall
<PAGE>

                                      -61-


effect a cash settlement of all amounts due and payable in respect thereof. To
the maximum extent permissible under applicable law, the Buyer shall direct the
operation of each Deferred Conveyance Subsidiary during the applicable Interim
Ownership Period. In all other respects the Sellers shall continue to operate
each Deferred Conveyance Subsidiary in the geographic areas in which it was
operated prior to the Closing in the ordinary course of business, consistent
with past practice, and otherwise at the direction of the Buyer. The Buyer shall
cooperate fully with the Sellers in connection with their performance of the
Deferred Operation Services, and shall provide to the Sellers, without charge,
such technical or other assistance and resources as the Sellers may reasonably
request in connection therewith.

         8.19.    Assumed Non-Competition Obligations. The Buyer agrees that it
                  ------- --------------- -----------
will comply, and cause the RECI Subsidiaries to comply, with the non-competition
and other obligations identified in Schedule 8.19, for the periods identified in

         8.20.    Required Financing.
                  -------- ---------

                  (a) The Buyer hereby agrees to use its best efforts to arrange
the financing contemplated by the CSFB Commitment Letters and to satisfy the
conditions set forth in the CSFB Commitment Letters on an expeditious basis.
These best efforts will include taking all actions required to satisfy the
conditions under the CSFB Commitment Letters but will not include the Buyer
being required to accept any commercially unreasonable terms. As provided in the
CSFB Commitment Letters, the Buyer will not unreasonably withhold its consent to
any request by CSFB and BMO to change the amount, pricing, terms and structure
of the Senior Facilities. The Buyer will enforce all of its rights under the
CSFB Commitment Letters and will not waive or amend any provision of the CSFB
Commitment Letters without the Sellers' prior written consent (which shall not
be unreasonably withheld or delayed), except that the Sellers' consent shall not
be required in connection with any waiver or amendment that will not adversely
impact the ability of the Buyer to obtain funding on a timely basis sufficient
for the Buyer to pay the Final Purchase Price and perform its other obligations
under this Agreement. The Buyer shall keep the Sellers informed of the status of
its financing arrangements, including providing written notification to the
Sellers as promptly as reasonably possible (but in any event within forty-eight
(48) hours) with respect to (i) any indication that CSFB may be unable to
provide the financing as contemplated by the CSFB Commitment Letters, including
without limitation, any indication from CSFB that there has occurred a Capital
Market Event (as defined in Section 10.4) or Financing Failure (as defined in
paragraph (c) below), (ii) any inability of the Buyer to satisfy any of the
conditions set forth in the CSFB Commitment Letters, and (iii) any adverse
developments relating to the financing contemplated by the CSFB Commitment
Letters. The Buyer shall provide reasonably prompt (and in any event within
forty-eight (48) hours) written notice to the Sellers if CSFB or BMO has
indicated to the Buyer that CSFB or BMO lender will be unable to provide the
financing contemplated by the CSFB Commitment Letters (a "Buyer Financing
                                                          ---------------

                                      -62-


                  (b) In the event a Capital Market Event has occurred, the
Buyer will use its best efforts to complete the financing contemplated by the
CSFB Commitment Letters as soon as possible after such Capital Market Event and
prior to June 30, 2000. These best efforts will include increasing the pricing
on the loans and changing the other terms and structure, including a reduction
in the total amount of financing to be provided, of the Senior Facilities to be
provided pursuant to the CSFB Commitment Letters as provided in the eighth
paragraph of the CSFB Commitment Letter relating to the secured facility and the
eighth paragraph of the CSFB Commitment Letter relating to the unsecured
facility. However, these best efforts will not include the Buyer being required
to accept any commercially unreasonable terms. At the Sellers' request, the
Buyer will discuss, and if requested meet to discuss, with the Sellers the
status of any negotiations between CSFB, BMO and the Buyer regarding any
proposed changes required to the Senior Facilities to complete the financing
contemplated by the CSFB Commitment Letters, and will use commercially
reasonable efforts to provide the Sellers with direct access to CSFB and BMO to
discuss such negotiations and proposed changes.

                  (c) In the event that the CSFB Commitment Letters are
terminated or CSFB and BMO otherwise do not provide financing under the CSFB
Commitment Letters, other than as a result of a Capital Market Event (a
"Financing Failure"), then if this Agreement has not been terminated, the Buyer
 --------- -------
will use its best efforts to obtain as promptly as practicable alternative debt
and/or equity financing sufficient to pay the Final Purchase Price and to fund
the reasonable working capital needs of the Purchased Business after the
Closing. These best efforts will include taking advantage of all financial
resources available to the Buyer but will not include the Buyer being required
to accept any commercially unreasonable terms. The Buyer will keep the Sellers
informed concerning the progress of its financing efforts and will meet with the
Sellers as reasonably requested to discuss these efforts.

                  (d) The Sellers agree to cooperate with the Buyer as
reasonably requested to facilitate the pursuit by the Buyer of its financing.
This cooperation includes: permitting the Buyer to make information about the
Purchased Business available on a confidential basis to its financing sources;
making certain members of senior management available to participate in Buyer's
presentations to its prospective lenders and investors; providing the Buyer with
unaudited consolidated balance sheets of the RECI Companies at March 31, 2000
and March 31, 1999 and the consolidated statements of operations and cash flows
of the RECI Companies for the three-month periods ended on such dates and other
financial information regarding the RECI Companies for use in disclosure
documents to be utilized in connection with the Buyer's financing efforts as
reasonably requested by the Buyer; and using their commercially reasonable
efforts to cause their outside auditors to deliver a comfort letter relating to
financial information regarding the RECI Companies included in any such
disclosure document. Any out-of-pocket expenses incurred by the Seller or their
Subsidiaries in connection with the foregoing will be reimbursed by the Buyer.

         8.21.    Hague Restructuring. With respect to the proposed
                  ----- -------------

Sellers will reimburse the Buyer for severance and related costs described in
Schedule 8.21 and incurred by the Buyer or any RECI Subsidiary after the
- -------- ----
Closing, promptly after receipt by the Sellers of documentation in reasonable
detail evidencing such payment. However, the total amount to be reimbursed by
the Sellers shall not exceed an amount equal to $9.8 million less amounts paid
by the RECI Subsidiaries with respect to such restructuring prior to the
Closing.

         8.22.    Foreign Exchange. At the Closing, the Buyer will assume the
                  ------- --------
Sellers' rights and obligations with respect to the foreign exchange contracts
and instruments listed on Schedule 8.22 and any similar contracts and
                          -------- ----
instruments entered into for the benefit of the Purchased Business consistent
with the provisions of Section 7.4.

         8.23.    Hawker Aircraft. With respect to the Hawker 800 aircraft
                  ---------------
included in the Acquired RECI Assets, the Sellers agree that prior to or as
promptly as practicable after Closing the aircraft will be repainted and receive
an airworthiness certification as described in Schedule 1.3 at the Sellers'

cost. In addition, an engine MPI (Major Periodic Inspection) will be performed
as described in Schedule 1.3, and the Sellers will pay for the cost of this
                -------- ---
service. The Sellers also agree that prior to delivery they will cause at their
cost to be completed the 12 month, 24 month and 48 month required inspections
(including non-destructive testing) in compliance with FAA airworthiness
requirements and the Raytheon Hawker recommended maintenance schedule. The
Sellers will perform or select the vendors to perform this work and will oversee
and control this work.

         8.24.    East Side Reservoir. The Buyer agrees that it will not assert
                  ---- ---- ---------
or pursue, and will not permit any Subsidiary to assert or pursue, any claim
against the Sellers or any RECI Subsidiary arising from the performance by the
RECI Companies prior to Closing of the East Side Reservoir Project Agreements
other than any claim for indemnification under Section 13.1 relating to a
Third-Party Claim (as defined in Article 13) and any claim pursuant to the
provisions of Section 3.3 or Section 4.3.

         8.25.    REOL. The Buyer agrees that without the Sellers' prior written
                  ----
consent it will not conduct any new business through Raytheon Ebasco Overseas
Ltd. ("REOL"), and in connection with the defense of any claim relating to the
Pakistani judgment described on Schedule 14.4, at the request of the Sellers the
                                -------- ----
Buyer will transfer the capital stock of REOL back to the Sellers for a purchase
price equal to its book value at such time.

         8.26.    Arayco Documents. The Buyer agrees that, effective as of the
                  ------ ---------
Closing, it will assume jointly and severally with RECI, all of RECI's
obligations under the Stock Purchase Agreement, between RECI, Raytheon
Constructors International, Inc. and United Rentals (North America), Inc., dated
as of May 20, 1999 (the "Arayco Purchase Agreement"), and the Ancillary
                         ------ -------- ---------
Agreements (as defined therein) to which RECI is a party. However, the parties
acknowledge and agree that they are effecting the foregoing assumption only to
fulfill a commitment of Raytheon to United Rentals, Inc., and this Section 8.26
is not intended to change the treatment, as between the Sellers and the Buyer,
of all of these obligations other than RECI's obligations under the June 25,
1999

National Supply Agreement, as Specified Seller Liabilities for purposes of this
Agreement. The Buyer acknowledges that RECI's obligations under this National
Supply Agreement constitute Specified Buyer Liabilities for purposes of this
Agreement.

         8.27.    Basic Ordering. (a) Raytheon's operating units will award
                  ----- --------
individual job orders to the Buyer for certain services, of the type described
in paragraph (d) below, subject to and on the terms and conditions listed below
and provided that Raytheon does not determine in its reasonable judgement that
awarding a particular job order to the Buyer would be inconsistent with
Raytheon's practices in specific circumstances, such as entering into labor
agreements, in a manner that is detrimental to Raytheon. At Buyer's request,
Raytheon will meet with the Buyer to discuss these practices and ways for the
Buyer to overcome any obstacles presented by these practices. Each order will
identify the specific work to be performed and the terms specific to the order
and will be subject to a definitive agreement containing terms and conditions
that are consistent with this Section 8.27 and otherwise customary for the type
of work to be performed.

                  (b) This Section 8.27 shall remain in effect for five (5)
years after the Closing Date.

                  (c) Job orders will be priced to reflect prevailing
competitive market rates for the class and type of service being provided,
including a 7% fee (i.e. profit) payable to the Buyer, provided that costs
(exclusive of fees payable to the Buyer) and other terms are competitive. Only
bids that offer competitive costs will be considered by Raytheon. Pricing for
both existing contracts and new bids will be reviewed and benchmarked annually.

                  (d) Subject to the other provisions of this Section 8.27,
Raytheon's operating units will endeavor to award job orders to the Buyer under
this Section 8.27 aggregating $40 million per year on a revenue basis. Services
subject to this Section 8.27 are operations and maintenance and construction
services in support of Raytheon's facilities.

                  (e) The quality of the Buyer's work and performance will be
reviewed by Raytheon annually and will be considered equally with cost
competitiveness in awarding and renewing job orders.

                  (f) In any year that this Section 8.27 is in effect, Raytheon
shall have the option to award job orders to parties other than the Buyer even
in the event that the Buyer meets the conditions of this Section 8.27 (including
the condition that Raytheon does not determine in its reasonable judgement that
the award of such a job order to the Buyer would be inconsistent with Raytheon's
practices in specific circumstances, such as entering into labor agreements, in
a manner that is detrimental to Raytheon), if, but only if, Raytheon pays the
Buyer the 7% fee (i.e. profit) included in the Buyer's bid; provided that
                                                            -------- ----
Raytheon shall have no obligation to pay the Buyer such a fee if the $40 million
annual target for such year has already been met pursuant to the provisions of
this
<PAGE>

                                      -65-


Section 8.27. If Raytheon exercises its option pursuant to this Section 8.27(f),
the Buyer's bid shall be counted toward the applicable $40 million annual
target.

                  (g) In the event that through contacts initiated by Raytheon,
any consortium partner of Raytheon awards the Buyer a job order to perform
services of the type described in Section 8.27(d), such order shall be counted
toward the $40 million annual target.

         8.28.    Receivables Termination Agreement. The Sellers and the Buyer
                  ----------- ----------- ---------
agree that they will use all commercially reasonable efforts required to obtain
the consent of Canadian Imperial Bank of Commerce ("CIBC") and its affiliate,
                                                    ----
Asset Securitization Cooperation Corporation ("ASCC"), to the Receivables

Termination Agreement, including modifying the Receivables Termination Agreement
as CIBC and ASCC may reasonably request, provided that such modifications do not
adversely affect in any material respect the rights or obligations of the Buyer
thereunder. If CIBC and ASCC do not consent to the Receivables Termination
Agreement, then Raytheon will cause REC Receivables Corporation to repurchase
all of the ASCC Receivables and Raytheon, REC Receivables Corporation, the
applicable REC Subsidiaries and the Buyer will enter into a receivables
termination agreement in substantially the same form as the Receivables
Termination Agreement, modified to remove CIBC and ASCC as a party and to
substitute Raytheon in place of CIBC and ASCC and as otherwise agreed by the
parties thereto.

accepting such offers (the "Seller Employees") will be deemed to have commenced
                            ------ ---------

compensation) at Closing (collectively with the Seller Employees, the "Assumed

bear no liability with respect thereto.

                  (c) The Sellers shall remain responsible for any severance
benefits, termination indemnity payments or similar payments, if any, owed to
any individual made an offer of employment as provided in paragraph (a) above
who does not accept such offer.

of Raytheon Employee Benefit Plans shall constitute Specified Seller Liabilities

Buyer will or will cause an RECI Subsidiary to be substituted as plan sponsor

Employee Benefit Plans, and Buyer (or such RECI Subsidiary) will succeed to all
powers, duties, rights and privileges relating to the sponsorship of the Assumed
Employee Benefit Plans and will assume all liabilities and obligations arising
out of or relating to sponsorship and maintenance of the Assumed Employee
Benefit Plans (which liabilities and obligations will constitute Specified Buyer

the RECI Subsidiaries will cease to maintain or participate in each Raytheon
Employee Benefit Plan and thereafter shall have no liabilities or obligations in
connection therewith except to the extent such liability or obligation is
accrued on the Cut-Off Date Balance Sheet or otherwise constitutes an Assumed
RECI Liability. From and after the Closing Date the RECI Companies will remain
responsible for all liabilities and obligations (which liabilities and
obligations will constitute Specified Buyer Liabilities for purposes of this
Agreement) arising out of or relating to sponsorship and maintenance of each
ERISA Plan and Non-ERISA Plan which is neither an Assumed Employee Benefit Plan
nor a Raytheon Employee Benefit Plan (each such Plan, collectively with the

faith to facilitate the effective transfer of responsibilities with respect to
ERISA and non-ERISA Plans required by this Section 9.2(a) on or as promptly as
possible after Closing. Without limiting the generality of the foregoing
sentence, Sellers will make available to the Buyer, and the Buyer will and after
Closing will cause the RECI Subsidiaries to make available to the Sellers, each
in accordance with Section 8.2 hereof, any information (including current and

Buyer).

                  (b) Collective Bargaining. On and after the Closing Date, the
                      ---------- ----------
Buyer shall provide and cause the RECI Subsidiaries to provide benefits to
Assumed Employees in units represented for collective bargaining, works council

other similarly situated employees from time to time after the Closing Date.
Buyer shall not be considered to have failed to meet the foregoing requirement
solely because it elects to continue to maintain (or cause the RECI Subsidiaries
to maintain) for the benefit of Assumed Employees any RECI Employee Benefit
Plan. Furthermore, the Buyer shall continue or cause to be continued the
provision of COBRA continuation coverage to individuals, whether or not Assumed
Employees, who qualified for the same on or prior to the Closing Date under each

as of the Closing Date. Following the Closing Date the Assumed Employees shall
be permitted to elect to take distributions (subject to applicable law) of their
accounts thereunder and, if such Assumed Employees so elect, to roll them over,
directly or otherwise, in accordance with applicable law and regulations, to an
individual retirement account or to one or more defined contribution retirement
plans qualified under Section 401(a) of the Code (the "Buyer Defined
                                                       ----- -------
Contribution Plans") and maintained by Buyer and the Buyer Defined Contribution

Plans shall accept such rollovers (including any plan loans). Furthermore, the
Buyer Defined Contribution Plans shall not be required to accept any transfer or
rollover of a plan loan unless the Assumed Employee electing such a transfer or
rollover elects to transfer or rollover his or her entire account balance under
the Raytheon Savings and Investment Plan as of the date

required to accept any rollover of property other than participant loans. The
Buyer Defined Contribution Plans shall recognize service of the Assumed
Employees with the Sellers and RECI Companies prior to the Closing Date for
eligibility and vesting purposes.

                  (e) Stock Options. Sellers shall retain responsibility for

to the Closing and fully vest all Assumed Employees who have an accrued benefit
under the Pension Plan.

                      ------ -- ------
shall (i), except where expressly provided otherwise, limit the discretion of
Buyer after Closing over the hiring, promotion, firing and other terms and
conditions of employment of any employee of Buyer or any of its Subsidiaries or
obligate the Buyer to continue any particular benefits for any particular period
after the Closing Date and (ii) without limitation on the generality or effect

         13.4.  Dollar Thresholds.
                ------ ----------

                (a)    With respect to any Misrepresentation Claim relating to a
representation or warranty that contains a materiality qualifier (whether by
reference to "Material Adverse Effect" or otherwise), except for
Misrepresentation Claims arising under Sections 5.5, 5.7(b), 5.8(f)(xi),
5.8(f)(xv), 5.12(b)(vi), 5.17(c) or 5.26(a) ("Qualified Misrepresentation
                                              --------- -----------------
Claims"), for purposes of determining whether any such breach exists for
- ------
purposes of this Article 13 such representations and warranties shall be deemed
not to include or be qualified by any such materiality qualifier. Neither the
Sellers nor the Buyer shall be liable to the other for any Misrepresentation
Claim (other than a Qualified Misrepresentation Claim) if the total Losses with
respect to such Misrepresentation Claim do not exceed $1,000,000, except with
respect to any Misrepresentation Claim arising under Sections 5.4, the second
sentence of Section 5.8(h), Section 5.9 or Section 5.14(a), for which the
Sellers shall not be responsible if the total Losses with respect to such
Misrepresentation Claim do not exceed $3,000,000 (collectively, "Minor Claims").
                                                                 ----- ------
The parties acknowledge that these $1,000,000 and $3,000,000 thresholds have
been designated only for those Misrepresentation Claims that are not Qualified
Misrepresentation Claims. Qualified Misrepresentation Claims will not be subject
to the $1,000,000 or $3,000,000 thresholds described above, but will be
interpreted for purposes of determining whether a breach has occurred taking
into account the materiality qualifiers set forth in the text of the applicable
representation and warranty. For this purpose, the parties acknowledge that the
$1,000,000/$3,000,000 thresholds do not represent any agreement between the
parties as to what constitutes a "material" matter for purposes of this
Agreement.

                (b)    The Sellers shall not be liable to the Buyer for any
Misrepresentation Claims unless and until the total Losses suffered by the Buyer
and its Affiliates with respect to all Misrepresentation Claims exceeds
$25,000,000, excluding Losses with respect to Minor Claims, and then only to the
extent of such excess. The Buyer shall not be liable to the Sellers or their
Affiliates for any Misrepresentation Claims unless and until the total Losses
suffered by the Sellers and their Affiliates with respect to all
Misrepresentation Claims exceeds $25,000,000, excluding Losses with respect to
Minor Claims, and then only to the extent of such excess.

                (c)    The total amount payable by the Sellers under Section
13.1(i) with respect to all Misrepresentation Claims, other than Specified
Misrepresentation Claims, shall not exceed $87,500,000. The total amount payable
by the Buyer under Section 13.2(i) with respect to all Misrepresentation Claims,
other than Specified Misrepresentation Claims, shall not exceed $87,500,000.

                (d)    No claim for indemnification under Section 13.1 or
Section 13.2, other than a Misrepresentation Claim (other than Specified
Misrepresentation Claims), shall be subject to any threshold amount or
deductible amount or cap on liability.

         13.5.  Claims.
                ------

                (a)    Any party seeking indemnification hereunder (the
"Indemnified Party") shall within five (5) business days notify the other party
 ----------- -----
hereto obligated to provide indemnification hereunder (the "Indemnifying Party")
                                                            ------------ -----
of any action, suit, proceeding, demand or breach (a "Claim") with respect to
                                                      -----
which the Indemnified Party claims indemnification hereunder, provided that
                                                              --------
failure of the Indemnified Party to give such notice shall not relieve any
Indemnifying Party of its obligations under this Article 13 except to the
extent, if at all, that such Indemnifying Party shall have been prejudiced
thereby. If such Claim relates to any action, suit, proceeding or demand
instituted against the Indemnified Party by a third party (a "Third Party
                                                              ----- -----
Claim"), upon receipt of such notice from the Indemnified Party, the
- -----
Indemnifying Party shall be entitled to participate in the defense of such Third
Party Claim, and if and only if each of the following conditions is satisfied,
the Indemnifying Party may assume the defense of such Third Party Claim, and in
the case of such an assumption the Indemnifying Party shall have the authority
to negotiate, compromise and settle such Third Party Claim:

                       (i)    the Indemnifying Party confirms to the Indemnified
         Party in writing that it is willing to assume the defense of such Third
         Party Claim in accordance with this Article 13; and

                       (ii)   the Indemnified Party does not give the
         Indemnifying Party written notice that it has determined, in the
         exercise of its reasonable discretion, that a conflict of interest
         makes separate representation by the Indemnified Party's own counsel
         advisable.

                If the Indemnifying Party has so elected to assume the defense
of any such Third Party Claim, such defense shall be conducted by counsel chosen
by the Indemnifying Party, provided that such counsel is reasonably satisfactory
to the Indemnified Party. The Indemnified Party shall retain the right to employ
its own counsel and to participate in the defense of any Third Party Claim, the
defense of which has been assumed by the Indemnifying Party pursuant hereto, but
the Indemnified Party shall bear and shall be solely responsible for its own
costs and expenses in connection with such participation.

                (b)    Notwithstanding the foregoing provisions of this Section
13.5, (i) no Indemnifying Party shall be entitled to settle any Third Party
Claim without the
<PAGE>

                                      -79-

Indemnified Party's prior written consent unless as part of such settlement the
Indemnified Party is released in writing from all liability with respect to such
Third Party Claim and (ii) no Indemnified Party shall be entitled to settle any
Third Party Claim without the Indemnifying Party's prior written consent unless
as part of such settlement the Indemnifying Party is released in writing from
all liability with respect to such Third Party Claim.

                (c)    In the event any Indemnified Party shall have a claim for
indemnification hereunder that does not involve a Third-Party Claim, the
Indemnified Party shall promptly send notice of such Claim to the Indemnifying
Party; provided that failure to give such notice shall not relieve any
Indemnifying Party of its obligations under this Article 13 except to the
extent, if at all, that such Indemnifying Party shall have been prejudiced
thereby. If the Indemnifying Party does not respond to such notice within 30
days after receipt thereof, it shall be deemed to have disputed the validity of
such claim. If the Indemnifying Party disputes or is deemed to have disputed
such Claim, such dispute shall be resolved by agreement of the Buyer and the
Sellers or in accordance with Section 16.13.

         13.6.  Losses Net of Tax Costs and Benefits. Losses under this Article
                ------ --- -- --- ----- --- --------
13 shall not include any Taxes payable as a result of any indemnity payment made
with respect to any claims under this Article 13 and Losses under this Article
13 will be calculated without regard to any tax benefits arising from the matter
giving rise to an indemnity claim for Losses under this Article 13.

         13.7.  Insurance Proceeds.
                --------- --------

                (a)    No Indemnifying Party shall be entitled to postpone
performance of any indemnification obligation under this Article 13 while an
insurance claim is pending. However, without limiting any of the provisions of
Sections 13.1 through 13.6, in connection with any Losses subject to
indemnification under this Article 13, all parties shall pursue and cooperate
with each other in giving notice of any claim to any insurer (including an
insurer of an Indemnified Party) from which recovery in respect of such Losses
is reasonably believed to be available and in pursuing recovery therefrom in
respect of such Losses; provided, however, that no Indemnified Party shall be
                        --------  -------
required to provide notice of or pursue recovery in respect of any claim under
the Indemnified Party's insurance policies where the Indemnified Party
determines in its sole discretion that such notice, pursuit, cooperation or
assistance could invalidate any portion of the coverage available under such
policy or result in the imposition of retroactive premiums or material
prospective premium increases. In addition, if an Indemnified Party makes such a
determination after it has notified its insurer, it shall be entitled to retract
such notice.

                (b)    If an Indemnified Party actually receives insurance
proceeds, the amount of the Losses for which such Indemnified Party is entitled
to indemnification under this Article 13 shall be reduced by the amount
received, net of any retroactive premiums or prospective premium increases. In
the event an Indemnified Party receives
<PAGE>

                                      -80-


insurance proceeds in respect of Losses after receiving payment in respect of
such Losses from the Indemnifying Party under this Article 13 and the amount of
insurance proceeds received exceeds the remaining unpaid balance of such Losses,
then the Indemnified Party shall promptly remit to the Indemnifying Party the
excess (if any) of (A) the sum of the amount therefore paid by the Indemnifying
Party in respect of such Losses plus the amount of insurance proceeds received,
less (B) the sum of the full amount of such Losses and any retroactive premiums
or prospective premium increases relating to such Losses. Nothing in this
Section 13.7 shall be deemed to waive or limit the subrogation rights of any
insurer.

         13.8. Scope of Indemnity. The Sellers and the Buyer each acknowledge
               ----- -- ---------
and agree that, after the Closing and except for equitable relief before or
after the Closing, including specific performance, its and their sole and
exclusive remedy with respect to any and all claims relating to the subject
matter of this Agreement shall be pursuant to the indemnification provisions set
forth in this Article 13 and the Tax Sharing Agreement. The provisions of the
Tax Sharing Agreement, and not this Article 13, shall allocate responsibility
between the Sellers and the Buyer for Taxes of the Purchased Business.

         13.9. Waiver of Statutory Claims. The Buyer hereby waives and releases
               ------ -- --------- ------
the Sellers and their other Subsidiaries from any and all Losses, known or
unknown, it may have under CERCLA (as defined in Article 14) or any other
statutes or regulations relating to environmental matters now or hereafter in
effect or any other statutes or regulations if the assertion of a right under
such statute or regulation would circumvent the intended effect of Section 13.8.
The Sellers hereby waive and release the Buyer from any and all Losses, known or
unknown, it may have under CERCLA or any other statutes or regulations relating
to environmental matters now or hereafter in effect or any other statutes or
regulations if the assertion of a right under such statute or regulation would
circumvent the intended effect of Section 13.8.

         16.3.  Entire Agreement. Except for the Fire Wall Letter and the
                ------ ---------
Ancillary Letter Agreement, this Agreement (including the Exhibits and Schedules
hereto) contains the entire understanding of the parties, supersedes all prior
agreements and understandings relating to the subject matter hereof and shall
not be amended except by a written instrument hereafter signed by all of the
parties hereto. EXCEPT AS SET FORTH IN ARTICLE 5 AND ARTICLE 13, SELLERS MAKE NO
REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION
ANY REPRESENTATION OR WARRANTY WITH RESPECT TO MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE, WITH RESPECT TO THE SALE OF THE PURCHASED SHARES OR THE
PURCHASED BUSINESS AND SUCH SALE IS MADE ON AN "AS IS" BASIS.

         16.4.  Governing Law. THE VALIDITY AND CONSTRUCTION OF THIS AGREEMENT
                --------- ---
SHALL BE GOVERNED BY THE INTERNAL LAWS (AND NOT THE CHOICE-OF-LAW RULES WHICH

OF NEW YORK.

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

         16.6.  Assigns. This Agreement shall be binding upon and inure to the
                -------
benefit of the parties hereto and their respective heirs, successors and
permitted assigns. Neither this Agreement nor the rights or obligations of any
party hereunder shall be assigned or delegated (by operation of law or
otherwise) by such party without the prior written consent of the other parties
hereto, except that the Buyer may assign its rights and obligations hereunder,
in whole or in part, to one or more wholly owned subsidiaries of the Buyer (but
no such assignment shall relieve the Buyer of any of its obligations hereunder).
Notwithstanding the foregoing provisions of this Section 16.6, the Buyer's
rights hereunder may be assigned as security to one or more financial
institutions providing financing to the Buyer and may be assigned pursuant to
the terms of the relevant security agreement, it being understood that no such
assignment shall release the Buyer from any of its obligations hereunder (or be
deemed to constitute an assumption by the assignee of such obligations) or
increase or otherwise modify the obligations of the Sellers hereunder.

         16.7.  Survival of Representations and Warranties. The representations
                -------- -- --------------- --- ----------
and warranties of the parties hereto contained in this Agreement (in each case
except as affected by the transactions contemplated by this Agreement) shall
survive the Closing and the consummation of the transactions contemplated
hereby. Such representations and warranties shall expire on the last day (if
any) on which a claim for indemnification may be made pursuant to Article 13 for
a breach thereof, unless such representation or warranty is the subject of a
pending claim pursuant to Article 13 on such date, in which case such
representation or warranty shall expire upon resolution of such claim. The
Terminated Representations will expire upon the occurrence of the Closing.

         16.8.  Further Assurances. From time to time, at the request of the
                ------- ----------
Buyer and without further consideration, each Seller shall execute and deliver
such further instruments of conveyance and transfer and take such other actions
as the Buyer may reasonably require to more effectively convey and transfer any
of the Purchased Shares or Acquired RECI Assets to the Buyer. From time to time,
at the request of the Sellers and without further consideration, the Buyer shall
execute and deliver such further instruments of assumption and take such other
actions as the Sellers may reasonably require to more effectively cause the
assumption by the Buyer of the Assumed RECI Liabilities.

         16.9.  No Implied Rights or Remedies. Except as otherwise expressly
                -- ------- ------ -- --------
provided herein, nothing herein expressed or implied is intended or shall be
construed to confer upon or to give any person, firm or corporation, except the
Sellers and the Buyer and as provided in Article 13 with respect to the Buyer
Indemnified Parties and Seller Indemnified Parties, any rights or remedies under
or by reason of this Agreement.

         16.10. Counterparts.  This Agreement may be executed in multiple
                ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         16.11. Public Statements or Releases. The parties hereto each agree
                ------ ---------- -- --------
that prior to Closing no party to this Agreement shall make, issue or release
any public announcement, statement or acknowledgment of the existence of, or
reveal the status of, this Agreement or the transactions provided for herein,
without first obtaining the consent of the other party hereto, which consent
shall not be unreasonably withheld or delayed. Nothing contained in this Section
16.11 shall prevent any party from making such public announcements as such
party may consider necessary or desirable in order to satisfy such party's legal
obligations (including under any applicable securities laws), provided that such
disclosing party shall to the extent practicable give prior notice to the other
party of the contents of, and requirement for, such disclosure.

         16.12. Nature of Obligations.  With respect to any covenant in this
                ------ -- -----------
Agreement applicable (prior to the Closing) to the RECI Subsidiaries, the
Sellers shall cause the applicable RECI Subsidiary to comply with such covenant.

         16.13. Arbitration.
                -----------

                (a)    All disputes or claims arising under or in any way
relating to this Agreement or to the acquisition of the Purchased Business by
the Buyer shall be settled by arbitration before a panel of three arbitrators
(with one designated by the Buyer and one designated by the Sellers, and the
third arbitrator designated by the first two) pursuant to the rules of the
American Arbitration Association. Any arbitrator designated by the Buyer or the
Sellers must be an "Independent Person." For the purposes of this Section 16.13,
                    ----------- ------
an "Independent Person" shall be an individual who is not and has not been (i) a
director, officer, employee, agent or shareholder of either party hereto, (ii) a
consultant to either party hereto, (iii) a person with a direct or indirect
financial interest in any contract with either party hereto, (iv) a director,
officer or key employee of a company at a time when such company was party to a
contract with either party hereto, or (v) a relative of any person referred to
in clauses (i), (ii), (iii) or (iv) above. As used in the immediately preceding
sentence, the term "either party hereto" shall be deemed to include any
Affiliates of the parties hereto. Any such arbitration shall take place in
Chicago, Illinois. Arbitration may be commenced at any time by either party
hereto giving written notice to the other party hereto that such dispute has
been referred to arbitration under this Section 16.13. The third arbitrator
shall be selected as prescribed above, but if the first two arbitrators do not
so agree within 30 days after the date of the notice referred to above, the
selection shall be made pursuant to the rules of the American Arbitration
Association from the Commercial Arbitration Panel (and not the Construction
Arbitration Panel) maintained by such Association. Any award rendered by the
arbitrators shall be conclusive and binding upon the parties hereto; provided,
                                                                     --------
however, that any such award shall be accompanied by a written opinion of the
- -------
arbitrators giving the reasons for the award. In making such award, the
arbitrators shall be authorized to award interest on any amount awarded. This
provision for arbitration shall be specifically enforceable by the Sellers and
the Buyer and the decision of the arbitrators in accordance herewith shall be
final and binding and there shall be no right of appeal therefrom. Each of the
Sellers and the Buyer shall pay its own expenses of arbitration and the expenses
of the arbitrators shall be equally shared; provided, however, that if in
                                            --------  -------
<PAGE>

                                      -92-

the opinion of the arbitrators any claim for indemnification or any defense or
objection thereto was frivolous or in bad faith, the arbitrators may assess, as
part of the award, all or any part of the arbitration expenses of the other
party (including reasonable attorneys' fees) and of the arbitrators against the
party raising such unreasonable claim, defense or objection.

                (b)    To the extent that arbitration may not be legally
permitted hereunder and the Sellers and the Buyer do not at the time of such
dispute or claim mutually agree to submit such dispute or claim to arbitration
either the Sellers or the Buyer may commence a civil action in a court of
appropriate jurisdiction to resolve disputes or claims hereunder. Nothing
contained in this Section 16.13 shall prevent the Sellers and the Buyer from
settling any dispute or claim by mutual agreement at any time.

                (c)    Neither party shall be precluded hereby from seeking,
from the courts of any jurisdiction, provisional or equitable remedies of a type
not available in arbitration, including without limitation, temporary
restraining orders and preliminary or permanent injunctions, nor shall the
pursuit of such provisional or equitable relief constitute a waiver or
modification of such party's right and obligation to arbitrate any related or
unrelated dispute which is otherwise subject to arbitration under this
Agreement, unless such waiver is expressed in writing and signed by such party.
In the event any person not a party to this Agreement shall commence any
interpleader or similar action which either directly or indirectly raises issues
which are subject to arbitration hereunder, the Sellers and the Buyer shall seek
a stay of such proceedings pending arbitration in accordance with this
Agreement.

                (d)    In the event of any Third Party Claim where the
Indemnifying Party does not assume the defense of such Third Party Claim,
nothing in this Section 16.13 shall prevent the Indemnified Party from
impleading the Indemnifying Party or otherwise joining the Indemnifying Party to
any litigation relating to such Third Party Claim.

                (e)    Disputes relating to the performance of the Indemnified
Project Subcontracts shall be resolved pursuant to the procedures set forth in
the Indemnified Project Subcontracts.

         16.14. Construction. The language used in this Agreement will be
                ------------
deemed to be the language chosen by the parties to express their mutual intent,
and no rule of strict construction will be applied against any party.

         16.15. Waiver of Jury Trial. EACH PARTY HERETO WAIVES ITS RIGHTS TO A
                ------ -- ---- -----
JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS AGREEMENT, ANY AGREEMENT, CONTRACT OR OTHER DOCUMENT OR
INSTRUMENT EXECUTED IN CONNECTION HEREWITH, OR ANY OF THE TRANSACTIONS
CONTEMPLATED HEREBY.

                                      -93-


         16.16. Waiver of Certain Damages. EACH OF THE SELLERS AND THE BUYER TO
                -------------------------
THE FULLEST EXTENT PERMITTED BY LAW, IRREVOCABLY WAIVES ANY RIGHTS THAT THEY MAY
HAVE TO INCIDENTAL, CONSEQUENTIAL OR SPECIAL (INCLUDING PUNITIVE OR MULTIPLE)
DAMAGES BASED UPON, OR ARISING OUT OF, THIS AGREEMENT OR ANY COURSE OF CONDUCT,
COURSE OF DEALING, STATEMENTS OR ACTIONS OF ANY OF THEM RELATING THERETO.

         16.17. Disclosure in Schedules. For purposes of this Agreement, with
                ---------- -- ---------
respect to any matter that is clearly disclosed in any portion of the Disclosure
Schedule in such a way as to make its relevance to the information called for by
another Section of this Agreement readily apparent, such matter shall be deemed
to have been included in the Disclosure Schedule in response to such other
Section, notwithstanding the omission of any appropriate cross-reference
thereto.

     capacity as Sub-Servicer to perform all of the duties and obligations of
     the Collection Agent set forth herein and in the Receivables Resale
     Agreement with respect to the Existing Receivables and Collections thereon.

          (b)  Without the prior written consent of the Special Purpose
     Purchaser and its assignees, Buyer shall not be permitted to delegate any
     of its duties or responsibilities as Sub-Servicer to any Person other than
     Raytheon or any of its Affiliates. If at any time CIBC shall, as permitted
     under Section 7.2.1 of the Receivables Resale Agreement, designate as
     Collection Agent any Person other than the Special Purpose Purchaser, all
     duties and responsibilities theretofore delegated by the Special Purpose
     Purchaser to Buyer may, at the discretion of CIBC, be terminated forthwith
     on written notice given by the Special Purpose Purchaser or CIBC (as
     assignee of the Special Purpose Purchaser) to Buyer.

          (c)  All Collections and other payments or distributions upon or in

     as it is acting in the capacity of Sub-Servicer, an irrevocable power of
     attorney to endorse all drafts, checks and other forms of payment made out

                                      -5-

     such power of attorney in favor of Buyer will terminate and have no further
     force or effect.

          (f)  Buyer shall exercise reasonable care in the performance of its
     duties under this Agreement and shall use the same degree of care and skill
     which it applies to its own property, subject to the restrictions imposed
     on Buyer by the terms of this Agreement.

     3.2.  Replacement of Sub-Servicer; Overdue Receivables.
           ------------------------------------------------

          (a)  In the event of any payment default under this Agreement by Buyer
     that is not cured within three (3) Business Days, or any other breach of
     this Agreement in any material respect by Buyer that is not cured within
     fifteen (15) Business Days, in either case, after the earlier of (i)
     Buyer's actual knowledge thereof and (ii) receipt by Buyer of written
     notice thereof by the Special Purpose Purchaser, ASCC or CIBC, the Special
     Purpose Purchaser may, without obtaining the consent of any party, and
     shall, at the request of ASCC or CIBC, remove Buyer as its Sub-Servicer and
     appoint a new Sub-Servicer, and notify Obligors of ASCC's ownership of the
     Existing Receivables. The Special Purpose Purchaser shall provide Buyer
     with three (3) Business Days' notice of such removal. In addition, CIBC may
     terminate Buyer's designation as Sub-Servicer as provided in Section
     3.1(b). Upon any removal of Buyer as a Sub-Servicer, Buyer shall cooperate
     with the Special Purpose Purchaser or CIBC, as applicable, in transferring
     Collections and enabling the successor Sub-Servicer to perform its duties
     under this Agreement. The Special Purpose Purchaser, ASCC and CIBC shall
     have the right to remove any successor Sub-Servicer and to take the other
     actions described above at any time in their sole discretion.

          (b)  If Buyer is removed as Sub-Servicer, Buyer shall provide and
     cause the REC Subsidiaries to provide the Special Purpose Purchaser or any
     successor Sub-Servicer designated by the Special Purpose Purchaser or CIBC,
     as applicable, with access at reasonable times during normal business hours

     related to the collection, administration and monitoring of Existing
     Receivables) reasonably requested by them and to permit such persons to
     have access at reasonable times during normal business hours to, and to
     copy, all software used by such Sub-Servicer in the collection,
     administration or monitoring of the Existing Receivables, to the extent
     permitted by existing software licenses of the REC Subsidiaries.

          (c)  In the event any Existing Receivable becomes more than sixty (60)
     days overdue, any of the Special Purpose Purchaser, ASCC or CIBC may, after
     delivery of written notice to Buyer, notify the related Obligor of

          (a)  Each REC Subsidiary has previously transferred to CIBC as agent
     for ASCC, the exclusive ownership and control of the Collection Account of
     such REC Subsidiary, as evidenced by the Collection Account Agreement to
     which such REC Subsidiary is a party, and such REC Subsidiary shall claim
     no further right, title and/or interest in and to such Collection Account
     nor any rights to withdraw funds therefrom except as provided in Section
     3.7. Each REC Subsidiary hereby authorizes the Special Purpose Purchaser
     and CIBC, as agent for ASCC, and agrees that the Special Purpose Purchaser
     and CIBC, as agent for ASCC, shall be entitled to, (i) endorse such REC
     Subsidiary's name on checks and other instruments representing Collections
     on Existing Receivables, (ii) enforce the Existing Receivables sold by such
     REC Subsidiary, and (iii) take such action as shall be reasonably necessary
     or desirable to cause all cash, checks and other instruments constituting
     Collections of Existing Receivables to come into the possession of the
     Special Purpose Purchaser (or its designees) rather than such REC
     Subsidiary.

          (b)  Each REC Subsidiary acknowledges and agrees that (i) at the
     Closing, such REC Subsidiary will deliver to the bank set forth opposite
     its name on Annex E hereto (the "Collection Bank") a letter of direction
                 ----- -              ---------- ----
     with respect to the Collection Account of such REC Subsidiary in the form
     of Annex F hereto (the "Collection Account Letter") and (ii) from and after
        ----- -              ---------- ------- ------
     the Closing, such REC Subsidiary shall not revoke, or amend the terms of,
     such Collection Account Letter, or otherwise issue any instructions or
     directions to such Collection Bank with respect to the Collection Account
     of such REC Subsidiary which are inconsistent with the terms of such
     Collection Account Letter, without obtaining the prior written consent of
     the Special Purpose Purchaser and CIBC.

     3.4.  Responsibilities of the REC Subsidiaries.  Anything herein to the
           ---------------- -- --- --- ------------
contrary notwithstanding, the exercise by the Special Purpose Purchaser (or its
assignees) of its rights hereunder shall not release the REC Subsidiaries or
Buyer from any of their duties or obligations with respect to any Existing
Receivables under this Agreement. Except as may otherwise be provided in the
Receivables Resale Agreement, neither the Special Purpose Purchaser nor any of
its assignees (including any Collection Agent) shall have any obligation or
liability with respect to any Existing Receivables, nor shall any of them be
obligated to perform the obligations of the REC Subsidiaries.

     3.5.  Application of Collections.  The REC Subsidiaries shall not be
           ----------- -- -----------
entitled to any Collections on the Existing Receivables. The Special Purpose
Purchaser shall be entitled to Collections on the Existing Receivables only as
provided in the Receivables Resale Agreement.


     3.6.  Receivables Reports.  So long as any Existing Receivables remain
           ----------- -------
outstanding, Buyer shall prepare a monthly information package for the Special
Purpose Purchaser and ASCC, showing Collections on the Existing Receivables and
Outstanding Balances and prepared generally in the form of Annex G hereto.
                                                           -------

     3.7.  Joint Account.
           ----- --------

          (a)  The Collection Account Letter of each REC Subsidiary will provide
     that the Collection Bank of such REC Subsidiary will transfer daily all
     amounts received into the Collection Account of the applicable REC
     Subsidiary to a bank account jointly created and controlled by Buyer and
     the Special Purpose Purchaser (the "Joint Account"), unless and until (i)
                                         ----- -------
     such Collection Bank receives notice in the form of a letter from both the
     Special Purpose Purchaser and Buyer instructing it to do otherwise or (ii)
     CIBC takes control of the Collection Account of such REC Subsidiary as
     provided in the Collection Account Agreement of such REC Subsidiary.

          (b)  Representatives of Buyer and the Special Purpose Purchaser will
     meet (either in person or telephonically) every Business Day to review
     collections received into the Collection Accounts and transferred to the
     Joint Account and to determine whether such amounts either (i) relate to
     Collections or other proceeds on Existing Receivables, and accordingly are
     the property of the Special Purpose Purchaser or ASCC ("SPP Funds") or (ii)
                                                             --- -----
     relate to collections or other proceeds on other receivables of Buyer or
     any of its Subsidiaries or other amounts owed to Buyer or any of its
     Subsidiaries, and accordingly, are the property of Buyer or any of its
     Subsidiaries ("Buyer Funds"). The Special Purpose Purchaser and Buyer will
                    -----------
     cause SPP Funds to be transferred to ASCC from the Joint Account, and Buyer
     Funds to be transferred to Buyer from the Joint Account, on a daily basis
     and as early in the day as practicable.

          (c)  Buyer will not assert any claim with respect to, including any
     right of offset or lien, any of SPP Funds, and will not otherwise interfere
     with the regular and periodic transfer of SPP Funds to ASCC as provided in
     paragraph (b) above, notwithstanding any claim Buyer may have against
     Raytheon or any of its Subsidiaries. The Special Purpose Purchaser will not
     assert any claim with respect to, including any rights of offset or lien,
     any of Buyer Funds and will not otherwise interfere with the regular and
     periodic transfer of Buyer Funds to Buyer as provided in paragraph (b)
     above,
<PAGE>

                                      -8-

     notwithstanding any claim the Special Purpose Purchaser or Raytheon or any
     of its other Subsidiaries may have against Buyer or any of its
     Subsidiaries.

          (d)  In the event that Buyer and the Special Purpose Purchaser are
     unable to determine within three (3) Business Days (or such longer period
     as the representatives of Buyer and the Special Purpose Purchaser may
     mutually agree) whether any particular funds constitute SPP Funds or Buyer
     Funds, Buyer and the Special Purpose Purchaser will retain the ____________
     office of Ernst & Young LLP (the "Account Reviewer") to determine whether
                                       ----------------
     such funds constitute SPP Funds or Buyer Funds pursuant to the terms of
     this Agreement, including the allocation provisions of Section 5.2. The
     Account Reviewer shall be instructed to complete its review and render a
     decision as soon as possible and in any event within fourteen (14) days
     after receipt of such instructions. Buyer and Special Purpose Purchaser
     will cooperate and provide the Account Reviewer with access to records and
     personnel as it requests. Buyer and the Special Purpose Purchaser shall be
     bound by the determination of the Account Reviewer. The fees and expenses
     of the Account Reviewer shall be paid one-half by Buyer and one-half by the
     Special Purpose Purchaser.

     3.8.  Sub-Servicer Fee.  In consideration of the Sub-Servicer's agreement
           ------------ ---
to perform the duties and obligations of the Collection Agent under the
Receivables Resale Agreement, so long as Buyer has not been removed as Sub-
Servicer hereunder pursuant to Section 3.2 and Buyer shall continue to perform
as Sub-Servicer hereunder, the Special Purpose Purchaser shall pay over to Buyer
a fee in the amount of (i) 1.25% of all Collections received on Existing
Receivables received and remitted to ASCC or the Special Purpose Purchaser
between the date of this Agreement and sixty (60) days thereafter, (ii) 0.75% of
all Collections received on Existing Receivables received and remitted to ASCC
or the Special Purpose Purchaser after the 60th day after this Agreement and
before the one hundred and twentieth (120th) day after the date of this
Agreement and (iii) 0.50% of all Collections on Existing Receivables received
and remitted to ASCC or the Special Purpose Purchaser thereafter. The foregoing
fee will be paid on a monthly basis with respect to all Collections remitted to
ASCC or the Special Purpose Purchaser during the preceding month, with such
payment to be made not later than 10 business days after delivery of the related
monthly report pursuant to Section 3.6. The foregoing fee will constitute the
sole compensation payable to Buyer for acting as a Sub-Servicer hereunder.

     Collection Account not later than the Business Day immediately following
     the date of Buyer's knowledge of, but not later than five (5) Business Days
     after, receipt of such Collections, and, at all times prior to such
     remittance, Buyer shall itself hold such Collections in trust, for the
     exclusive benefit of the Special Purpose Purchaser and its assigns.

     4.2.  Negative Covenants of Buyer.  Buyer, individually and in its capacity
           -------- --------- -- -----
as a Sub-Servicer, will not, and will cause the REC Subsidiaries not to, unless
the Special Purpose Purchaser and CIBC have otherwise consented in writing, such
consent not to be unreasonably withheld or delayed:

          (a)  Except as provided herein, sell, assign (by operation of law or
     otherwise) or otherwise dispose of, or create or suffer to exist any
     security interest, lien or encumbrance upon or with respect to, Existing
     Receivables, Collections thereon, proceeds of Existing Receivables held in
     any Collection Account, or any books or records (including computer
     software) related to the Existing Receivables, or assign any right to
     receive income in respect thereof.

          (b)  (i)  Amend or otherwise modify any term of any Existing
     Receivable, or (ii) amend, modify or waive any term or condition of any
     contract related thereto, in the case of this clause (ii), so as to impair
     in any material respect the collectibility of any Existing Receivable.

          (c)  Make any change in the character of the Purchased Business (as
     defined in the Stock Purchase Agreement) relating to the REC Subsidiaries

     Receivables to be made to the Special Purpose Purchaser or to the
     Collection Bank of any REC Subsidiary.

          (e)  Deposit or otherwise credit, or cause to be so deposited or

                                   ARTICLE 5
                   ALLOCATION OF PAYMENT AND RELATED MATTERS

     5.1.  Certain Actions.  After the date of this Agreement, except as
           ------- -------
contemplated by Section 4.2(b), Buyer will not and will cause the REC
Subsidiaries not to intentionally take any action or fail to take any such
action if as a result of such action or inaction an Obligor on an Existing
Receivable would no longer be required to pay such Existing Receivable, would be
entitled to pay less than the full amount of such Existing Receivable or would
be entitled to delay any payments on such Existing Receivables.

     5.2.  Allocation of Payment.  Unless otherwise designated by the applicable
           ---------- -- -------
Obligor in writing, all payments received from any Obligor on an Existing
Receivable will be applied to Existing Receivables and other Receivables owed by
such Obligor (including other Receivables outstanding at the Closing) first to
the Existing Receivables, and shall be allocated among the Existing Receivables
based on aging, with the oldest outstanding Existing Receivable to be paid
first. Buyer will not and will cause the REC Subsidiaries not to, without the
prior consent of the Special Purpose Purchaser, and the Special Purpose
Purchaser will not, without the prior consent of Buyer, direct or request any
Obligor on an Existing Receivable to designate any particular payment in any
particular manner. In addition, Buyer will not and will cause the REC
Subsidiaries not to, without the prior written consent of the Special Purpose
Purchaser and CIBC, such consent not to be unreasonably withheld or delayed,
inform Obligors on Existing Receivables that the Existing Receivables have been
sold by the REC Subsidiaries or that someone other than the REC Subsidiaries or
Buyer will be the recipient of any payments made on Existing Receivables.
Notwithstanding anything to the contrary herein contained, at such time as an
Obligor is no longer an Obligor on an Existing Receivable, Buyer may send
notices to such Obligor as Buyer deems appropriate, including notices intended
to ensure that payments made on Receivables thereafter are not deposited into a
Collection Account.

     5.3.  Dispute Resolution.  Notwithstanding the foregoing provisions of this
           ------- ----------
Article 5, in the event any Obligor disputes any Existing Receivable or asserts
a defense to payment on any Existing Receivable, Buyer will provide the Special
Purpose
<PAGE>

                                      -12-

Purchaser with prompt notice thereof and will provide information to the Special
Purpose Purchaser as reasonably requested relating to such dispute or claim. The
Special Purpose Purchaser will control the settlement of any dispute or defense
to payment relating to an Existing Receivable.

which ASCC or CIBC may have hereunder or under applicable law, each party hereto
hereby agrees to indemnify ASCC or CIBC and their respective officers,
directors, agents and employees (each an "Indemnified Party") from and against

a breach of this Agreement, excluding, however, the following:

                                      -17-

               (a)  Indemnified Amounts to the extent final judgment of a court
     of competent jurisdiction holds such Indemnified Amounts resulted from
     breach of the Receivables Resale Agreement by ASCC or CIBC, gross
     negligence on the part of ASCC or CIBC or willful misconduct on the part of
     ASCC or CIBC or the Indemnified Party seeking indemnification;

               (b)  Indemnified Amounts to the extent the same includes losses
     in respect of Receivables that prove to be uncollectible on account of the
     insolvency, bankruptcy or lack of creditworthiness of the related Obligor;
     or

               (c)  Taxes imposed by the jurisdiction in which such Indemnified
     Party's principal executive office is located, on or measured by the
     overall net income of such Indemnified Party to the extent that the
     computation of such taxes is consistent with (i) the characterization of
     the purchases under the Receivables Resale Agreement as true sales or (ii)
     the characterization of the transactions under the Receivable Resale
     Agreement as creating indebtedness of ASCC for purposes of taxation.

If and to the extent that the foregoing undertaking may be unenforceable for any
reason, the parties hereto hereby agree to make the maximum contribution to the
payment of the amounts indemnified against in this Section 11.1 which is
permissible under applicable law.

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

          (a)  Raytheon shall be responsible for and shall hold the Buyer

     Group and all Taxes with respect to Consolidated State Tax Returns
     attributable to any Tax period (but not limited to the Taxes) of a RECI
     Subsidiary ending on or prior to the Closing Date (including any Taxes

     and
<PAGE>

                                      -3-

               (ii) all Income Taxes with respect to RECI.

Subject to the provisions of Article 3, Raytheon shall prepare (or cause to be
prepared) and file (or cause to be filed) on a timely basis any Raytheon
Affiliated Group U.S. federal Income Tax Returns or Consolidated State Tax
Returns for Tax periods ending on or prior to the Closing Date that are due
(including all applicable extensions) or may be filed after the Closing Date.
Raytheon shall pay (or cause to be paid) all Taxes shown or required to be shown
to be due on such Tax Returns.  Such Tax Returns shall not, without Buyer's
prior written consent, contain any new elections that would have a material
adverse effect on the financial condition or tax position of the RECI
Subsidiaries after the Closing Date.

          (b)  With respect to any U.S. state or U.S. local Income Taxes (other
than those referred to in paragraph (a) above) and foreign national, state and
local Income Taxes of the RECI Subsidiaries (or any Affiliated Group which
includes any of the RECI Subsidiaries) attributable to any Tax period that
either ends on or prior to the Closing Date or includes but does not end on the
Closing Date:

               (i)   with respect to any such Tax periods that end on or prior
     to the Closing Date, Raytheon shall be responsible for (and shall hold the
     Buyer harmless against) all such Income Taxes;

               (ii)  with respect to any such Tax periods of a RECI Subsidiary
     that include but do not end on the Closing Date, Raytheon shall be
     responsible for (and shall hold the Buyer harmless against) all such Income
     Taxes attributable to the period ending on the Closing Date, such portion
     to be that amount that bears the same ratio (but not less than zero or
     greater than one) to the total Tax liability for the Tax period that the
     taxable income of the applicable RECI Subsidiary during that portion of the
     Tax period ending on the Closing Date bears to its taxable income for the
     entire applicable Tax period; and

               (iii) with respect to any such Tax periods that include but do
     not end on the Closing Date, the Buyer shall be responsible for (and shall
     hold Raytheon harmless against) all such Income Taxes attributable to the
     period after the Closing Date, such portion to equal the excess of the
     total Tax liability for the Tax period for the applicable RECI Subsidiary
     over the amount of the Tax liability for the applicable RECI Subsidiary and
     Tax period as computed under clause (ii) above.

     For purposes of this Section 2.1(b), all Income Taxes attributable to a
Section 338(h)(10) Election referred to in Article 4 shall be deemed to arise on
the Closing Date.  Raytheon's obligations under clauses (i) and (ii) above shall
be net of any reserve on the final Cut-Off Date Balance Sheet, as described
below.  Subject to the provisions of Article 3, the Buyer shall prepare (or
cause to be prepared) and file (or cause to be filed) on a timely basis any Tax
Returns of the RECI Subsidiaries for Income Taxes described in this Section
2.1(b) for applicable Income Tax periods that are due (including all applicable
extensions) or that may be filed after the Closing Date.  Raytheon's liability
for any Income Tax under this Section 2.1(b) shall not exceed what its liability
therefor would have been had the applicable Tax Return been prepared on a basis
consistent with the RECI Subsidiaries' respective prior Tax Returns to the
extent permitted
<PAGE>

                                      -4-

under all applicable Income Tax laws, rules and regulations. The Buyer shall pay
(or cause to be paid) all Taxes shown to be due on such Tax Returns. To the
extent that Raytheon is responsible for any portion of such Income Taxes
pursuant to this Section 2.1(b), Raytheon shall be liable for and reimburse the
Buyer for that portion of such Income Taxes (excluding any penalties caused by
acts or failures to act of the Buyer, including without limitation Buyer's
preparation (or causing to be prepared) of the applicable Tax Return) in excess
of any aggregate reserve for such U.S. state or local or foreign national, state
or local Income Taxes set forth on the Cut-Off Date Balance Sheet (as finally
adjusted pursuant to the Purchase Agreement). Any such reimbursement shall occur
within ten (10) business days of Raytheon's receipt of notice of payment by the
Buyer.

          (c)  Raytheon shall be entitled to all refunds of Income Taxes of
the type and for all Tax periods referred to in paragraph (a) above or paragraph
(b) above, except with respect to any Tax Return for which the Buyer has paid a
portion of the relevant Income Taxes as provided in paragraph (b) above, in
which case the Buyer shall be entitled to a pro rata portion of such refund
                                            --- ----
based on the proportion of applicable Income Taxes paid by the Buyer.

          (d)  All computations required by this Section 2.1 shall be made on
the basis of a closing of the books as of the close of business on the Closing
Date, consistent with the computation of the final Closing Date Balance Sheet.

     2.2  Non-Income Taxes.
          -----------------

          (a)  Raytheon shall be responsible for and shall hold the Buyer
harmless against all Non-Income Taxes of the RECI Subsidiaries attributable to
any Tax period ending on or prior to the Closing Date. With respect to any Non-
Income Taxes of the RECI Subsidiaries attributable to any Tax period that
includes but ends after the Closing Date, (i) Raytheon shall be responsible for
and shall hold the Buyer harmless against the Non-Income Taxes of the RECI
Subsidiaries attributable to the period prior to and including the Closing Date
and (ii) the Buyer shall be responsible for and shall hold Raytheon harmless
against the Non-Income Taxes of the RECI Subsidiaries attributable to the period
after the Closing Date.

          (b)  Notwithstanding the foregoing, the Buyer and Raytheon shall each
bear and be responsible for paying half of any sales, use, transfer, stamp,
documentary, registration, business and occupation or similar Tax (including
related interest and penalties) ("Transaction Taxes") imposed by any
Governmental Entity with respect to the sale of the Purchased Shares and the
Acquired RECI Assets to the Buyer, regardless of whether the applicable Taxing
authority seeks to collect such Tax from Raytheon or the Buyer. The Buyer shall
also be responsible for (i) administering the payment of such Transaction Taxes,
(ii) defending or pursuing any proceedings relating thereto, and (iii) paying
any expenses related thereto; provided, that Raytheon will reimburse Buyer for
                              --------
half of any reasonable out-of-pocket expenses related thereto that are
authorized in advance by Raytheon within thirty (30) days of its receipt of
written notice of payment by Buyer. The Buyer shall also give prompt notice to
Raytheon of any proceeding relating to Transaction Taxes, shall keep Raytheon
reasonably informed of the progress thereof, shall consult Raytheon regarding
such proceeding and shall not settle any such
<PAGE>

                                      -5-

proceeding without the written consent of Raytheon, which shall not be
unreasonably withheld. Raytheon shall give prompt written notice to the Buyer of
any proposed adjustment or assessment of any Transaction Tax with respect to the
transaction, or of any examination of said transaction in a sales, use, transfer
or similar Tax audit.

          (c)  Buyer shall be responsible for and shall hold the Raytheon
harmless against all Non-Income Taxes of the RECI Subsidiaries attributable to
any period after the Closing Date.

          (d)  The Buyer shall prepare (or cause to be prepared) and (except
with respect to RECI) file (or cause to be filed) on a timely basis any Tax
Returns for Non-Income Taxes of the RECI Companies that are due (including all
applicable extensions) or may be filed after the Closing Date, it being
understood that Raytheon shall be responsible for filing (or causing to be
filed) such Tax Returns due (including all applicable extensions) through the
Closing Date. In the case of returns prepared (or caused to be prepared) by the
Buyer for RECI, the Buyer will deliver completed Tax Returns to Raytheon along
with the Buyer's share of the Tax payment, if any, shown to be due thereon, no
later than five (5) business days before such Tax Returns are due, and Raytheon
hereby agrees to file such Tax Returns no later than five (5) business days
after its receipt thereof from Buyer and to pay the Tax payment shown to be due
thereon (or the amount received in respect thereof from Buyer, if less). Such
Tax Returns shall be prepared on a basis consistent with the RECI Companies'
prior Tax Returns to the extent permitted under all applicable Tax laws, rules
and regulations. The Buyer shall pay (or cause to be paid) all Non-Income Taxes
shown or required to be shown to be due on such Tax Returns. To the extent that
Raytheon is responsible for any portion of such Non-Income Taxes pursuant to
this Article 2, Raytheon shall be liable for and reimburse the Buyer for that
portion of such Non-Income Taxes (excluding any penalties caused by acts or
failures to act of the Buyer, including without limitation Buyer's preparation
(or causing to be prepared) of the applicable Tax Return) in excess of any
aggregate reserve for such Non-Income Taxes set forth on the Cut-Off Date
Balance Sheet (as finally adjusted pursuant to the Purchase Agreement). Any such
reimbursement shall occur within ten (10) business days of Raytheon's receipt of
notice of payment by the Buyer.

          (e)  Buyer shall be entitled to all refunds of Non-Income Taxes for
which it is liable under this Section 2.2, and Raytheon shall be entitled to all
refunds of Non-Income Taxes for which it is liable under this Section 2.2.

          (f)  For any Non-Income Taxes of a RECI Subsidiary based on sales or
revenue (other than Transaction Taxes), the allocation of responsibility between
Raytheon and the Buyer shall be based on the sales or revenues, as applicable,
taken into account in the final Closing Date Balance Sheet. For any real estate
Taxes or other property or asset-based Taxes of a RECI Subsidiary (other than
Transfer Taxes), the allocation of responsibility between Raytheon and the Buyer
shall be based on the number of days the applicable asset was held by the RECI
Subsidiary in the applicable Tax period through the Closing Date as compared to
the number of days the applicable asset was held by the RECI Subsidiary in the
applicable Tax period after the Closing Date. For all other Non-Income Taxes of
a RECI Subsidiary, the allocation of responsibility to the Buyer or Raytheon
shall be made by reference to the specific
<PAGE>

                                      -6-

asset, activity or payment producing such Tax liability, and if the Tax
liability cannot practically be so allocated, then pro rata based on the number
                                                   --------
of days in the applicable Tax period prior to and including the Closing Date as
compared to the number of days in the Tax period after the Closing Date, or
based on some other method determined jointly by the Buyer and Raytheon to be
more appropriate.


         Article 3. Cooperation on Tax Matters; Conduct of Proceedings
         -------------------------------------------------------------

         (a)  The Buyer and Raytheon shall cooperate fully and in good faith,
as and to the extent reasonably requested by the other party, in connection with
the preparation and filing of Tax Returns pursuant to Article 2 and any audit,
litigation or other proceeding with respect to Taxes, it being understood that a
party's failure to so cooperate, or to perform its obligations under this
Article 3, shall excuse the other party from its indemnification obligations
hereunder with respect to the affected Taxes if and to the extent the failure
has an adverse effect on the indemnifying party. Such cooperation shall include,
subject to the following sentence, the retention and (upon the other party's
request) the provision of records and information which are reasonably relevant
to such preparation and filing and to any audit, litigation or other proceeding
relating thereto and making employees reasonably available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder. The Buyer agrees to retain (and to cause the RECI
Subsidiaries to retain) all books and records with respect to Taxes pertinent to
the RECI Subsidiaries relating to any Tax period for which Raytheon may have an
indemnity obligation hereunder for not less than ten (10) years after the
Closing Date (and, to the extent notified by Raytheon, until the expiration of
any extensions of the applicable statutes of limitations), and shall not destroy
or otherwise dispose of any such books and records without first providing
Raytheon with a reasonable opportunity to review and copy the same. In addition,
with respect to any Tax Returns that Raytheon is responsible for filing under
this Agreement, the Buyer agrees that it will cause its employees and employees
of the RECI Subsidiaries, to the extent they have done so in the past, to
prepare tax reporting packages and initial drafts of Tax Returns for the RECI
Companies prepared on a basis consistent with past practice to the extent
permitted under all applicable Tax laws, rules and regulations. Prior to filing
any Income Tax Returns of any RECI Subsidiary for which Raytheon has agreed to
indemnify the Buyer (in whole or in part) pursuant to Article 2, the Buyer shall
provide Raytheon with a reasonable opportunity to review the applicable Tax
Returns and any necessary or appropriate applicable supporting workpapers and
schedules, and shall obtain the prior written consent of Raytheon to the filing
thereof, such consent not to be unreasonably withheld, conditioned, or delayed;
provided, that without limiting the provisions of the first sentence of this
paragraph, the failure to provide a reasonable opportunity to review or a lack
of consent, or the failure to make any changes to the Tax Returns requested by
Raytheon, shall excuse Raytheon from its indemnification obligations to the
extent Raytheon can demonstrate that it was prejudiced thereby. The Buyer shall
provide Raytheon with a copy of all Non-Income Tax Returns for which Raytheon
has agreed to indemnify the Buyer (in whole or in part) pursuant to Article 2,
along with any necessary or appropriate applicable supporting workpapers and
schedules, within thirty (30) days of the filing thereof, and not later than at
the time the Buyer provides Raytheon with notice of payment and a request for
reimbursement hereunder.

          (b)  Except as set forth in Section 2.2(b), each party shall be solely
responsible for defending any audit, litigation or other proceeding with respect
to Taxes for which it is liable hereunder, and shall have the authority to
negotiate, compromise and settle any such audit, litigation or other proceeding.
In the case of any Tax for which Raytheon is liable hereunder, Raytheon shall
keep the Buyer reasonably informed as to the progress of any such audit,
litigation or other proceeding to the extent it relates to such Taxes, and
shall, if the Buyer so requests in writing, permit the Buyer at its expense to
participate in any such audit, litigation or other proceeding insofar as it
relates to any RECI Subsidiary; provided that Raytheon shall not settle any such
                                -------- ----
audit, litigation, or other proceeding without the Buyer's consent (not to be
unreasonably withheld, conditioned or delayed) if such settlement would or could
reasonably be expected to increase the Tax liabilities of Buyer or any of its
Affiliates (including any RECI Subsidiary) for any period after the Closing
Date. In the alternative, Raytheon may, by written and revocable notice to the
Buyer, at any time request the Buyer to control any audit, litigation, or other
proceeding (as and to the extent set forth in the notice) that Raytheon would
otherwise be entitled to control hereunder, in which case the Buyer shall
diligently proceed with the defense of that audit, litigation, or other
proceeding, shall keep Raytheon reasonably informed as to the progress of any
such audit, litigation or other proceeding, shall, if Raytheon so requests in
writing, permit Raytheon at its expense to participate in any such audit,
litigation or other proceeding, and shall not settle any such audit, litigation,
or other proceeding without Raytheon's consent, which shall not be unreasonably
withheld. If Raytheon requests that Buyer control an audit that Raytheon would
otherwise have been entitled to control hereunder, Raytheon will reimburse Buyer
for all reasonable out-of-pocket (but not internal or overhead) expenses
incurred by the Buyer in connection therewith and authorized in advance by
Raytheon. If, as a result of any audit, litigation or proceeding Raytheon,
Buyer, or any RECI Company is required to pay any additional Taxes hereunder,
each party shall (without duplication of the other provisions of this agreement)
reimburse the other party for any portion of such Taxes paid by that other party
(or its Affiliates) for which the reimbursing party is liable hereunder within
ten (10) business days after receipt of notice of payment.

                    Article 4. Section 338(h)(10) Election
                    --------------------------------------

          (a)  Raytheon shall join with the Buyer in making elections under
Section 338(h)(10) of the Code, and the regulations promulgated thereunder, and
any applicable analogous provision of state or local law, with respect to the
sale and acquisition of the stock of the RECI Subsidiaries hereunder (the
"Section 338(h)(10) Elections").

          (b)  In the case of any Section 338(h)(10) Elections that are made in
accordance with Section 4(a) hereof, the Buyer will be responsible for preparing
and filing all documents and materials necessary in connection with making any
such Section 338(h)(10) Election. Each of Raytheon and the Buyer agree to
cooperate with each other in connection therewith (including, without
limitation, signing and returning any documents sent to such party for its
signature in connection therewith within fifteen (15) days of its receipt of
such documents). The Buyer and Raytheon agree that for purposes of any Section
338(h)(10) Election they will agree to the valuation, or the method of
valuation, of the assets of the RECI

<PAGE>

                                      -8-

Subsidiaries within three (3) months after the Closing Date, and will reflect
such agreement in a written supplement to this Agreement. In preparing such
allocation both the Buyer and Raytheon will act in a reasonable manner
consistent with the principles set forth in Annex A hereto. The Buyer and
                                            ----- -
Raytheon will file all Tax Returns in a manner consistent with such a Section
338(h)(10) Election and the valuation of the assets determined as provided
above.

              Article 5. Carrybacks; Adjustments Affecting Timing
              ---------------------------------------------------

          (a)  If there is an Adjustment to any item reported on a Tax Return
filed with respect to Raytheon or any Affiliate of Raytheon (including any RECI
Company) for a period ending on or before the Closing Date (a "Prior Period")
that results in an increase in the Tax liabilities of Raytheon or an Affiliate
of Raytheon (including any RECI Company to the extent Raytheon is liable for
such Tax liabilities under this Agreement) and such Adjustment results in a
corresponding Adjustment to items reported on a Tax Return filed by or with
respect to the Buyer or any RECI Subsidiary or any Affiliate for a period
beginning after the Closing Date, with the result that the Tax liabilities of
the Buyer, such RECI Subsidiary, or such Affiliate with respect to such period
are reduced, then the Buyer shall pay to Raytheon an amount equal to such
reduction in Taxes of such RECI Subsidiary or Affiliate, such payment being
limited to the increase in the Tax liabilities of the Raytheon and its
Affiliates (including the RECI Companies) (as reduced by any prior payments by
Buyer to Raytheon under this sentence).

          (b)  If there is an Adjustment to any item reported on a Tax Return
filed with respect to Raytheon or any Affiliate of Raytheon (including any RECI
Company) for a Prior Period that results in an aggregate decrease in the Tax
liabilities of Raytheon and its Affiliates (including any RECI Company to the
extent Raytheon is liable for such Tax liabilities under this Agreement) and
such Adjustment results in a corresponding Adjustment to items reported on a Tax
Return filed by or with respect to the Buyer or any RECI Subsidiary or any
Affiliate for a period beginning after the Closing Date, with the result that
the Tax liabilities of the Buyer, such RECI Subsidiary, or such Affiliate with
respect to such period are increased, then Raytheon shall pay to the Buyer an
amount equal to such increase in Taxes of such RECI Subsidiary or Affiliate,
such payment being limited to the aggregate decrease in the Tax liabilities of
the Raytheon and its Affiliates (including the RECI Companies) (as reduced by
any prior payments by Raytheon to the Buyer under this sentence).

          (c)  Any payment by a party under this Article 5 shall be due within
thirty (30) days after the later of the realization of the Tax decrease or the
incurring of the increase in Taxes. Any Tax reduction will be deemed to have
been received when cash payments are received from the applicable Tax authority
with respect to a claim for refund or when a Tax Return reflecting the benefit
of the Adjustment is filed, and any Tax increase will be deemed to have been
incurred when a Tax Return reflecting the increase is filed.

                        Article 6. Long-Term Contracts
                        ------------------------------

          (a)  In the case of any Transferred Risk E&C Contract that is a Long-
Term Contract, the Buyer and Raytheon shall for all federal and state Income Tax
purposes (including without limitation the application of the lookback method
described in Code Section 460(b)(2)) take into account all amounts paid by the
customer and all contract costs incurred attributable thereto on the basis of a
constructive completion of such Long-Term Contract by the applicable Selling
Group member on the Closing Date.

          (b)  Raytheon shall be responsible for reporting all taxable income
properly accruing under each Transferred Risk E&C Contract that is a Long-Term
Contract through the Closing Date and paying all Taxes (including, when due, any
lookback interest when payable) payable with respect to that period (taking into
account all amounts paid by the customer, all contract costs incurred through
the Closing Date and all other amounts required to be included by reason of the
constructive termination of such Long-Term Contract on the Closing Date), while
the Buyer shall be responsible for reporting all taxable income properly
accruing under each Transferred Risk E&C Contract that is a Long-Term Contract
after the Closing Date and paying all Taxes (including lookback interest)
payable with respect to that period (taking into account all amounts paid by the
customer (other than collection of amounts taken into account by the Selling
Group), and all contract costs incurred after the Closing Date). Any lookback
interest refunds for periods through the Closing Date shall accrue to Raytheon,
while any lookback interest refunds for periods after the Closing Date shall
accrue to the Buyer.

          (c)  For purposes of this Article 6:

               (i)  there shall be treated as amounts paid by the customer to
     the Selling Group member party thereto prior to the Closing Date and
     attributable to an Transferred Risk E&C Contract that is a Long-Term
     Contract (A) all amounts received with respect thereto on or prior to the
     Closing Date and (B) any then unpaid accounts receivable, unbilled work in
     progress, claims, disputes and retentions, to the extent (but only to the
     extent) those items are reflected in the final Cut-Off Date Balance Sheet;
     and

               (ii) there shall be treated as contract costs incurred prior to
     the Closing Date attributable to an Transferred Risk E&C Contract that is a
     Long-Term Contract all costs properly accrued as of the Closing Date,
     determined on a basis consistent with the final Cut-Off Date Balance Sheet.

          (d)  Raytheon and the Buyer agree to provide the other party any
assistance reasonably necessary or appropriate to carry out the computations
required by, and to file Tax Returns (including refund claims) necessary or
appropriate to give effect to, this Article 6.

       Article 7. Certain Post-Closing Events Relating to Foreign Taxes
       ----------------------------------------------------------------

     Buyer agrees not to take or cause to be taken prior to January 1 of the
year following the year in which the Closing Date occurs any of the following
actions in respect of any RECI Subsidiary that is not a United States entity if
that action would reduce the earnings and profits of that RECI Subsidiary for
its United States federal taxable year including the Closing Date attributable
to the shares of that RECI Subsidiary under Section 1248 of the Code below the
amount that would be so attributable to such shares if such taxable year had
ended on the Closing Date: (i) the payment of an actual or constructive
                            -
dividend; (ii) the triggering of a deemed dividend under Section 956 of the
          --
Code; (iii) a sale of stock subject to Section 304 of the Code;  (iv) a
       ---                                                        --
reorganization involving or liquidation or (except as specifically contemplated
hereby) deemed liquidation of the RECI Subsidiary; and (v) a change in
                                                        -
accounting method.  Buyer agrees not to take, or cause to be taken, any action
(other than an action in the ordinary course of business), if the effect of that
action would be to increase the amounts included in any of Raytheon's gross
income under Section 951 of the Code for Raytheon's taxable year that includes
the Closing Date.  Notwithstanding the foregoing, the parties agree to discuss
in good faith any actions proposed by the Buyer that would be inconsistent with
the agreements set forth in this Article 7, and further agree that Raytheon may,
in its good faith discretion, agree to permit Buyer to undertake any such action
if the Buyer is able to provide an indemnity, satisfactory to Raytheon, against
any adverse Tax effects resulting from the action.

NBV  =          Net Book Value, as reflected on the final Closing Date Balance
                Sheet.

FMV  =          Gross Fair Market Value (i.e., fair market value without regard
                to mortgages, liens, pledges or other liabilities).

                The parties agree to use all reasonable good faith efforts to
                reach mutual agreement as to such Gross Fair Market Values on an
                entity by entity basis. If the parties cannot reach agreement
                thereon as to any asset or assets, such disagreement shall be
                referred for resolution to a nationally recognized independent
                appraisal or certified public accounting firm mutually
                acceptable to Raytheon and the Buyer (a "Tax Referee"). If the
                parties cannot agree on such a Tax Referee, the Tax Referee
                shall be selected by two nationally recognized

          certified public accounting firms, one picked by the Buyer and one
          picked by Raytheon; provided, however, that the Tax Referee so
          selected may not then represent (other than in connection with the
          provisions of this Section) the Buyer, Raytheon, or any Affiliate of
          either. The decision of the Tax Referee shall be final and binding on
          the parties. The fees of the Tax Referee shall be shared equally by
          Raytheon and the Buyer.

P    =    The deemed sale price, determined applying Section 336(h)(10) and
          Treasury Regulation Section 1.338(h)(10)-1(f), in excess of the sum of
          the allocations to Class I, II, III assets, as reflected above, if
          any.

- -----------
                         Contractor and the Subcontractor intend that the
                         Subcontractor cause the applicable RECI Companies to
                         perform, on a cost-reimbursed basis, all obligations
                         under the Prime Contract. The Subcontractor will
                         perform the Subcontract at the direction of the Prime
                         Contractor. This will include attending and
                         participating in all regularly scheduled meetings with
                         the owner, consortium members, vendors, specialty
                         contractors and others.

Seller Access:           The Prime Contractor and its representatives,
- --------------
                         including any third party consultant retained by the
                         Prime Contractor, will be permitted to have access to
                         and examine and take copies of the books and records of
                         the Subcontractor and the RECI Companies relating to
                         the Project. The Subcontractor will provide the Prime
                         Contractor with copies of all internal and external
                         project reports and correspondence as generated or

                         entitled to place one or more employees or consultants
                         on-site at the Indemnified Projects to observe the
                         performance of the Indemnified Projects and the
                         performance by the Subcontractor of its obligations
                         under the Subcontract. In addition, the Prime
                         Contractor and the Subcontractor have appointed
                         liaisons, as indicated in Annex A, to meet and discuss
                                                   -------

                         Liaisons"). These ongoing meetings will include monthly
                         --------
                         project reviews and weekly progress meetings. The
                         Subcontractor may not designate a replacement Project
                         Liaison without the consent of the Prime Contractor,

                         delayed.

                          ------------------
                         for cause, as reasonably determined by the
                         Subcontractor) and not permit any RECI Subsidiary to
                         terminate (otherwise than for cause, as reasonably
                         determined by the Subcontractor) the employment of the
                         individuals identified in Annex A as "Key Persons" with

                         respect to such Project and will continue to assign
                         such personnel to the performance of the Project to a
                         degree consistent with the degree to which such
                         personnel were so assigned at April 13, 2000 (taking
                         into account changes in project status over time). In
                         addition, for the life of the Subcontract the
                         Subcontractor will not terminate (otherwise than for
                         cause, as reasonably determined by the Subcontractor)
                         and will not permit any RECI Subsidiary to terminate

                         the employment of any other individuals (other than
                         craft labor and local field hires) working on such
                         Project and will continue to assign them to work on
                         such Project until their particular responsibilities
                         are fulfilled or they are no longer necessary due to
                         changes in the work mix for such Project. If any such
                         individual referred to in this paragraph is terminated
                         for cause or voluntarily terminates his or her
                         employment, then neither the Buyer nor any of its
                         Affiliates will hire that individual for the life of
                         the Subcontract. If any individuals referred to in the
                         preceding sentence voluntarily terminate their
                         employment or die or become disabled prior to the time
                         that they are no longer required for the appropriate
                         Project as provided in the preceding sentence, the
                         Subcontractor will or will cause the RECI Subsidiaries
                         to use commercially reasonable efforts to promptly
                         replace such individuals with appropriately qualified
                         individuals. Any replacements for the Key Persons
                         referred to above during the Performance Period will be
                         subject to the Prime Contractor's prior approval, not
                         to be unreasonably withheld or delayed. The
                         Subcontractor will also use commercially reasonable
                         efforts to maintain staffing levels, including the
                         labor forces of subcontractors and vendors, consistent
                         with the current and projected staffing levels for the
                         Specified Projects set forth on Annex A (taking into
                                                         -------

                         resources (tools, equipment, scaffolding, etc.) as
                         required. In addition, the Subcontractor will not

                         termination of a vendor or subcontractor for default,

     with the limits of coverage in place as of the Closing and, with respect to
     project-specific insurance relating to the Projects, will name the Prime
     Contractor as a named insured and/or loss payee as their interest may
     appear. The allocable cost of maintaining this insurance will constitute an
     Other Reimbursable Cost.

               -------------
     Subcontractor with an ESR as of the Cut-Off Date with respect to the

     the event the Subcontractor completes the Project and achieves final
     acceptance at a cost less than the ECAC reflected on this ESR, excluding
     any forecasted liquidated damages or back charge recoveries and excluding
     any overhead and business development cost (the "Adjusted ECAC") as
                                                      -------------

     of such cost savings to the Subcontractor within thirty (30) days after the
     Prime Contractor and the Subcontractor determine the final amount, if any,
     of the cost savings.  Any increase in revenue as compared to the revenue
     forecast in the ESR described above will increase the target Adjusted ECAC
     for purposes of determining cost underruns.

                         arrangements comparable to those described in the
                         Section 8.3 of the Stock Purchase Agreement, with the
                         intent of implementing, as closely as practicable, the
                         contractual relationships between Prime Contractor and
                         Subcontractor contemplated by this Exhibit.


Termination:             In addition to any termination provisions in the
- -----------
                         Prime Contract (which will be incorporated into the
                         Subcontract), the Prime Contractor may terminate the
                         Subcontractor's engagement at any time Appropriate
                         provisions of the Subcontract, including provisions
                         relating to exculpation and indemnification, will
                         survive any such termination.

                         any kind relating to the Project) will not be
                         transferred. The parties may also choose not to
                         transfer certain subcontracts or other ancillary
                         agreements (whether because of consents, requirements
                         for contractors, engineers or other licenses, tax
                         planning or other reasons) and will enter into
                         alternative arrangements that achieve to the maximum
                         extent possible the economic intent of the parties.

                         Contractor will be entitled to retain such assets upon
                         completion of the Project or cause the Subcontractor,
                         pursuant to the Subcontract, to dispose of such Project
                         Specific Assets and remit the proceeds to Prime
                         Contractor. The Prime Contractor and Subcontractor will
                         separately inventory and identify (by stickers, etc.)
                         the Project Specific Assets upon commencement of the
                         Subcontract.

RECI Company:            The Subcontractor will maintain the existence and good

                         assign them to work on such Project until their
                         particular responsibilities are fulfilled or they are
                         no longer necessary due to changes in the work mix for
                         such Project. If any such individual referred to in
                         this paragraph is terminated for cause or voluntarily
                         terminates his or her employment, then neither the
                         Buyer nor any of its Affiliates will hire that
                         individual for the life of the Subcontract. If any

                         disabled prior to the time that they are no longer
                         required for the appropriate Project as provided in the
                         preceding sentence, the Subcontractor will or will

                         reasonable efforts to promptly replace such individuals

                         replacements for the Key Persons referred to above
                         during the Performance Period will be subject to the
                         Prime Contractor's prior approval, not to be
                         unreasonably withheld or delayed. The Subcontractor
                         will also use commercially reasonable efforts to
                         maintain staffing levels, including the labor forces of
                         subcontractors and vendors, consistent with the current
                         and projected staffing levels for the Specified

                    Subcontractor's obligations under the Subcontract in
                    addition to any claims under Section 13.2(ii) of the Stock
                    Purchase Agreement for breach of its obligations under the
                    Subcontract; provided, however, that in any case in which
                    the Subcontractor uses commercially reasonable efforts to
                    perform and comply with its obligations under the
                    Subcontract and takes all reasonable steps to abide by the

                    responsible under the Ancillary Letter Agreement.

                         (ii)   The Subcontractor will and will cause the RECI

                    under any other Project Agreement or to non-contract
                    parties, to the extent not related to ASCC Receivables or
                    Retained Claims (the treatment of which is addressed in the
                    Stock Purchase Agreement or Receivables Termination
                    Agreement), will be remitted to the Prime Contractor within
                    two (2) business days after receipt and until then will be
                    held in trust.

                         (iii)  The Subcontractor will not be authorized to, and
                    will not permit any RECI Subsidiary to, waive, modify or

                    performed under the Project Agreements within the time
                    periods required under the Project Agreements and within the

          (i)  Insurance. During the performance of the Projects the
               ---------
     Subcontractor will and will cause the RECI Subsidiaries to maintain the
     insurance required under the terms of the Project Agreements consistent
     with the limits of coverage in place as of the Closing and, with respect to
     project-specific insurance relating to the Projects, will name the Prime
     Contractor as a named insured and/or loss payee as their interest may
     appear. The allocable cost of maintaining this insurance will constitute an
     Other Reimbursable Cost.

          (j)  Cost Savings.  At Closing the Prime Contractor shall provide the
               -------------
     Subcontractor with an ESR as of the Cut-Off Date with respect to the
     Project.  Such ESR shall be prepared consistent with past practices.  In
     the event the Subcontractor completes the Project and achieves final
     acceptance at a cost less than the ECAC reflected on this ESR, excluding
     any forecasted liquidated damages or back charge recoveries and excluding
     any overhead and business development cost (the "Adjusted ECAC") as
                                                      -------------
     evidenced by documentation satisfactory to the Prime Contractor, the Prime
     Contractor and the Subcontractor will share such cost savings equally and
     accordingly, the Prime Contractor shall remit an amount equal to one-half
     of such cost savings to the Subcontractor within thirty (30) days after the
     Prime Contractor and the Subcontractor determine the final amount, if any,
     of the cost savings.  Any increase in revenue as compared to the revenue
     forecast in the ESR described above will increase the target Adjusted ECAC
     for purposes of determining cost underruns.

Taxes:                   The parties will structure the arrangements
- -----
                         contemplated by the Subcontract in a manner that will
                         minimize Taxes, to the extent permitted by law.

Assignment:              The parties will work to obtain prior to Closing all
- ----------
                         consents or novations required to implement the
                         Subcontract. If any such consent or novations is not
                         received by Closing, the parties will enter into
                         arrangements comparable to those described in the
                         Section 8.3 of the Stock Purchase Agreement, with the
                         intent of implementing, as closely as practicable, the
                         contractual relationships between Prime Contractor and
                         Subcontractor contemplated by this Exhibit.

Termination:             In addition to any termination provisions in the Prime
- -----------
                         Contract (which will be incorporated into the
                         Subcontract), the Prime Contractor may terminate the
                         Subcontractor's engagement at any time Appropriate
                         provisions of the Subcontract, including provisions
                         relating to exculpation and indemnification, will
                         survive any such termination.

                         senior management, and then arbitration consistent with
                         Section 16.13 of the Stock Purchase Agreement except
                         that AAA Construction Industry rules shall apply.


Asset Transfers:         With respect to Section 1.4(l) of the Stock Purchase
- ---------------
                         Agreement, the parties will determine which assets
                         relating to the Project will be transferred to RECI.
                         The parties expect that all contracts and working
                         capital will be transferred to RECI, but that tangible

                         transfer certain subcontracts or other ancillary
                         agreements (whether because of consents, requirements
                         for contractors, engineers or other licenses, tax
                         planning or other reasons) and will enter into
                         alternative arrangements that achieve to the maximum
                         extent possible the economic intent of the parties.
                         With respect to any Project Specific Assets, the Prime
                         Contractor will be entitled to retain such assets upon
                         completion of the Project or cause the Subcontractor,
                         pursuant to the Subcontract, to dispose of such Project
                         Specific Assets and remit the proceeds to Prime
                         Contractor. The Prime Contractor and Subcontractor will
                         separately inventory and identify (by stickers, etc.)
                         the Project Specific Assets upon commencement of the
                         Subcontract.

                         standing of the RECI Companies party to the Project

                         determined by the Subcontractor) the employment of the

                         such personnel to the performance of the Project to a

                         into account changes in project status over time). In

                         and will not permit any RECI Subsidiary to terminate
                         (otherwise than for cause, as reasonably determined by
                         the Subcontractor) the employment of any other
                         individuals (other than craft labor and local field
                         hires) working on such Project and will continue to
                         assign them to work on such Project until their
                         particular responsibilities are fulfilled or they are
                         no longer necessary due to changes in the work mix for
                         such Project. If any such individual referred to in
                         this paragraph is terminated for cause or voluntarily
                         terminates his or her employment, then neither the
                         Buyer nor any of its Affiliates will hire that
                         individual for the life of the Subcontract. If any
                         individuals referred to in the preceding sentence
                         voluntarily terminate their employment or die or become
                         disabled prior to the time that they are no longer
                         required for the appropriate Project as provided in the
                         preceding sentence, the Subcontractor will or will
                         cause the RECI Subsidiaries to use commercially
                         reasonable efforts to promptly replace such individuals
                         with appropriately qualified individuals. Any
                         replacements for the Key Persons referred to above
                         during the Performance Period will be subject to the
                         Prime Contractor's prior approval, not to be
                         unreasonably withheld or delayed. The Subcontractor
                         will also use commercially reasonable efforts to
                         maintain staffing levels, including the labor forces of
                         subcontractors and vendors, consistent with the current
                         and projected staffing levels for the Specified
                         Projects set forth on Annex A (taking into account

                         subcontractor for default, as reasonably determined by
                         the Subcontractor and subject to approval of the Prime
                         Contractor, not to be unreasonably withheld) any of the

                    under Section 13.2(ii) of the Stock Purchase Agreement for
                    breach of its obligations under the Subcontract; provided,
                    however, that in any case in which the Subcontractor uses
                    commercially reasonable efforts to perform and comply with
                    its obligations under the Subcontract and takes all
                    reasonable steps to abide by the directions of the Prime
                    Contractor and the terms of the Subcontract, it will be

                    performance prior to and after the Closing, of the
                    Subcontract or the Project Agreements), except for any
                    obligations for which the Buyer is responsible under the
                    Ancillary Letter Agreement.

                         (ii)   The Subcontractor will and will cause the RECI

                    claims for equitable adjustment and other claims relating to
                    the Project against the customers, consortium members,

                    the customer under the Prime Contract or any other party
                    under any other Project Agreement or to non-contract
                    parties, to the extent not related to ASCC Receivables or

                    Agreement), will be remitted to the Prime Contractor within
                    two (2) business days after receipt and until then will be
                    held in trust.

                         (iii)  The Subcontractor will not be authorized to, and
                    will not permit any RECI Subsidiary to, waive, modify or

          (i)  Insurance. During the performance of the Projects the
               ---------
     Subcontractor will and will cause the RECI Subsidiaries to maintain the
     insurance required under the terms of the Project Agreements consistent
     with the limits of coverage in place as of the Closing and, with respect to
     project-specific insurance relating to the Projects, will name the Prime
     Contractor as a named insured and/or loss payee as their interest may
     appear. The allocable cost of maintaining this insurance will constitute an
     Other Reimbursable Cost.

          (j)  Cost Savings.  At Closing the Prime Contractor shall provide the
               -------------
     Subcontractor with an ESR as of the Cut-Off Date with respect to the
     Project.  Such ESR shall be prepared consistent with past practices.  In
     the event the Subcontractor completes the Project and achieves final
     acceptance at a cost less than the ECAC reflected on this ESR, excluding
     any forecasted liquidated damages or back charge recoveries and excluding
     any overhead and business development cost (the "Adjusted ECAC") as
                                                      -------------
     evidenced by documentation satisfactory to the Prime Contractor, the Prime
     Contractor and the Subcontractor will share such cost savings equally and
     accordingly, the Prime Contractor shall remit an amount equal to one-half
     of such cost savings to the Subcontractor within thirty (30) days after the
     Prime Contractor and the Subcontractor determine the final amount, if any,
     of the cost savings.  Any increase in revenue as compared to the revenue
     forecast in the ESR described above will increase the target Adjusted ECAC
     for purposes of determining cost underruns.


Taxes:                   The parties will structure the arrangements
- -----
                         contemplated by the Subcontract in a manner that will
                         minimize Taxes, to the extent permitted by law.

Assignment:              The parties will work to obtain prior to Closing all
- ----------
                         consents or novations required to implement the

                         received by Closing, the parties will enter into
                         arrangements comparable to those described in the
                         Section 8.3 of the Stock Purchase Agreement, with the
                         intent of implementing, as closely as practicable, the
                         contractual relationships between Prime Contractor and
                         Subcontractor contemplated by this Exhibit.


Termination:             In addition to any termination provisions in the
- -----------
                         Prime Contract (which will be incorporated into the
                         Subcontract), the Prime Contractor may terminate the
                         Subcontractor's engagement at any time Appropriate
                         provisions of the Subcontract, including provisions
                         relating to exculpation and indemnification, will
                         survive any such termination.

- -------
Resolution:              Internal mediation between Project Liaisons and then
- ----------
                         senior management, and then arbitration consistent with
                         Section 16.13 of the Stock Purchase Agreement except
                         that AAA Construction Industry rules shall apply.

Asset Transfers:         With respect to Section 1.4(l) of the Stock Purchase
- ---------------
                         Agreement, the parties will determine which assets
                         relating to the Project will be transferred to RECI.
                         The parties expect that all contracts and working
                         capital will be transferred to RECI, but that tangible
                         assets including leases covering the same, but
                         excluding any tools, equipment and materials originally
                         costed to the project ("Project Specific Assets"),
                                                 -----------------------
                         Intellectual Property and computer software (including
                         licenses covering the same), collective bargaining and

                         licenses and permits, and books and records (including
                         site plans, surveys, soil and substratus studies,
                         architectural drawings, plans and specifications,
                         engineering, electrical and mechanical plans and
                         studies, feasibility studies, environmental studies,
                         audits and assessments and other plans and studies of
                         any kind relating to the Project) will not be
                         transferred. The parties may also choose not to
                         transfer certain subcontracts or other ancillary
                         agreements (whether because of consents, requirements
                         for contractors, engineers or other licenses, tax
                         planning or other reasons) and will enter into
                         alternative arrangements that achieve to the maximum
                         extent possible the economic intent of the parties.
                         With respect to any Project Specific Assets, the Prime
                         Contractor will be entitled to retain such assets upon
                         completion of the Project or cause the Subcontractor,
                         pursuant to the Subcontract, to dispose of such Project
                         Specific Assets and remit the proceeds to Prime
                         Contractor. The Prime Contractor and Subcontractor will
                         separately inventory and identify (by stickers, etc.)
                         the Project Specific Assets upon commencement of the
                         Subcontract.

RECI Company:            The Subcontractor will maintain the existence and good
                         standing of the RECI Companies party to the Project
                         Agreements until performance is completed.

                      labor and local field hires) working on such Project and
                      will continue to assign them to work on such Project until
                      their particular responsibilities are fulfilled or they
                      are no longer necessary due to changes in the work mix for
                      such Project. If any such individual referred to in this
                      paragraph is terminated for cause or voluntarily
                      terminates his or her employment, then neither the Buyer
                      nor any of its Affiliates will hire that individual for
                      the life of the Subcontract. If any individuals referred

                      that they are no longer required for the appropriate
                      Project as provided in the preceding sentence, the
                      Subcontractor will or will cause the RECI Subsidiaries to
                      use commercially reasonable efforts to promptly replace
                      such individuals with appropriately qualified individuals.
                      Any replacements for the Key Persons referred to above
                      during the Performance Period will be subject to the Prime
                      Contractor's prior approval, not to be unreasonably
                      withheld or delayed. The Subcontractor will also use
                      commercially reasonable efforts to maintain staffing
                      levels, including the labor forces of subcontractors and
                      vendors, consistent with the current and projected
                      staffing levels for the Specified Projects set forth on

                      scaffolding, etc.) as required. In addition, the

                      Subcontractor and subject to approval of the Prime
                      Contractor, not to be unreasonably withheld) any of the

               Subsidiary in the performance or nonperformance of the
               Subcontractor's obligations under the Subcontract in addition to
               any claims under Section 13.2(ii) of the Stock Purchase Agreement
               for breach of its obligations under the Subcontract; provided,
               however, that in any case in which the Subcontractor uses
               commercially reasonable efforts to perform and comply with its
               obligations under the Subcontracts and takes all reasonable steps
               to abide by the directions of the Prime Contractor and the terms
               of the Subcontract, it will be deemed not to have breached such
               obligations. Except as provided or referred to in the preceding
               sentence, notwithstanding anything to the contrary herein
               contained, the Prime Contractor will be responsible for, and will
               release and hold the Subcontractor and the RECI Subsidiaries
               harmless from and against, any and all Losses (as defined in
               Section 13.1 of the Stock Purchase Agreement) related to or
               arising out of the Subcontract or the Project Agreements
               (including without limitation all obligations and liabilities,
               including obligations and liabilities to non-contract parties,
               under or arising in connection with the performance prior to and

               except for any obligations for which the Buyer is responsible
               under the Ancillary Letter Agreement.

                    (ii)   The Subcontractor will and will cause the RECI
               Subsidiaries to use commercially reasonable efforts to assist the
               Prime Contractor in pursuing change orders and claims for
               equitable adjustment and other claims relating to the Project
               against the customers, consortium members, suppliers,
               subcontractors, vendors and non-contract parties. Any cash
               received by the Subcontractor or the RECI Subsidiaries from any
               such change orders or claims or from the customer under the Prime
               Contract or any other party under any other Project Agreement or
               to non-contract parties, to the extent not related to ASCC
               Receivables or Retained Claims (the treatment of which is
               addressed in the Stock Purchase Agreement or Receivables
               Termination Agreement), will be remitted to the Prime Contractor
               within two (2) business days after receipt and until then will be
               held in trust.

                    (iii)  The Subcontractor will not be authorized to, and will
               not permit any RECI Subsidiary to, waive, modify or amend any
               term of the Project Agreements.

                    (iv)   In performing its obligations under the Subcontract,
               the Subcontractor will act and will cause the RECI Subsidiaries
               to act in good faith and use commercially reasonable efforts to
               perform the work remaining to be performed under the Project
               Agreements within the time periods required under the Project
               Agreements and within the ECACs for the Project Agreements as in
               effect on the Closing Date and referred to in (j) below.

                    (i)    Insurance. During the performance of the Projects the
                           ---------
               Subcontractor will and will cause the RECI Subsidiaries to
               maintain the insurance required under the terms of the Project
               Agreements consistent with the limits of coverage in place as of
               the Closing and, with respect to project-specific insurance
               relating to the Projects, will name the Prime Contractor as a
               named insured and/or loss payee as their interest may appear. The
               allocable cost of maintaining this insurance will constitute an
               Other Reimbursable Cost.

                    (j)    Cost Savings. At Closing the Prime Contractor shall
                           ------------
               provide the Subcontractor with an ESR as of the Cut-Off Date with
               respect to the Project. Such ESR shall be prepared consistent
               with past practices. In the event the Subcontractor completes the
               Project and achieves final acceptance at a cost less than the
               ECAC reflected on this ESR, excluding any forecasted liquidated
               damages or back charge recoveries and excluding any overhead and
               business development cost (the "Adjusted ECAC") as evidenced by
                                               -------------
               documentation satisfactory to the Prime Contractor, the Prime
               Contractor and the Subcontractor will share such cost savings
               equally and accordingly, the Prime Contractor shall remit an
               amount equal to one-half of such cost savings to the
               Subcontractor within thirty (30) days after the Prime Contractor
               and the Subcontractor determine the final amount, if any, of the
               cost savings. Any increase in revenue as compared to the revenue
               forecast in the ESR described above will increase the target
               Adjusted ECAC for purposes of determining cost underruns.


Taxes:                The parties will structure the arrangements contemplated
- -----                 by the Subcontract in a manner that will minimize Taxes,
                      to the extent permitted by law.

Assignment:           The parties will work to obtain prior to Closing all
- ----------            consents or novations required to implement the
                      Subcontract. If any such consent or novations is not
                      received by Closing, the parties will enter into
                      arrangements comparable to those described in the Section
                      8.3 of the Stock Purchase Agreement, with the intent of
                      implementing, as closely as practicable, the contractual
                      relationships between Prime Contractor and Subcontractor
                      contemplated by this Exhibit.


Termination:          In addition to any termination provisions in the Prime
- -----------           Contract (which will be incorporated into the
                      Subcontract), the Prime Contractor may terminate the
                      Subcontractor's engagement at any time Appropriate
                      provisions of the Subcontract, including provisions
                      relating to exculpation and indemnification, will survive
                      any such termination.

Dispute
- -------
Resolution:           Internal mediation between Project Liaisons and then
- ----------            senior management, and then arbitration consistent with
                      Section 16.13 of the Stock Purchase Agreement except that
                      AAA Construction Industry rules shall apply.

Asset Transfers:      With respect to Section 1.4(l) of the Stock Purchase
- ---------------       Agreement, the parties will determine which assets
                      relating to the Project will be transferred to RECI. The
                      parties expect that all contracts and working capital will
                      be transferred to RECI, but that tangible assets including
                      leases covering the same, but excluding any tools,
                      equipment and materials originally costed to the project
                      ("Project Specific Assets"), Intellectual Property and
                        -----------------------

                      collective bargaining and employment agreements and other
                      agreements with employees or their representatives,
                      governmental licenses and permits, and books and records
                      (including site plans, surveys, soil and substratus
                      studies, architectural drawings, plans and specifications,
                      engineering, electrical and mechanical plans and studies,
                      feasibility studies, environmental studies, audits and
                      assessments and other plans and studies of any kind
                      relating to the Project) will not be transferred. The
                      parties may also choose not to transfer certain
                      subcontracts or other ancillary agreements (whether
                      because of consents, requirements for contractors,
                      engineers or other licenses, tax planning or other
                      reasons) and will enter into alternative arrangements that
                      achieve to the maximum extent possible the economic intent
                      of the parties. With respect to any Project Specific
                      Assets, the Prime Contractor will be entitled to retain
                      such assets upon completion of the Project or cause the
                      Subcontractor, pursuant to the Subcontract, to dispose of
                      such Project Specific Assets and remit the proceeds to
                      Prime Contractor. The Prime Contractor and Subcontractor
                      will separately inventory and identify (by stickers, etc.)
                      the Project Specific Assets upon commencement of the
                      Subcontract.

RECI Company:         The Subcontractor will maintain the existence and good
- ------------          standing of the RECI Companies party to the Project
                      Agreements until performance is completed.
