              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Allied Waste Industries, Inc. ("Allied" or the "Company"), is
incorporated under the laws of the state of Delaware. Allied is a solid waste
management company providing non-hazardous waste collection, transfer, recycling
and disposal services in selected markets.

         The condensed consolidated financial statements include the accounts of
Allied and its subsidiaries. All significant intercompany accounts and
transactions are eliminated in consolidation. The condensed consolidated balance
sheet as of December 31, 1996, which has been derived from audited consolidated
financial statements, and the unaudited interim condensed consolidated financial
statements included herein have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission (the "SEC"). As applicable
under such regulations, certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. The Company believes that
the presentations and disclosures herein are adequate to make the information
not misleading when read in connection with the Company's Annual Report on Form
10-K. The condensed consolidated financial statements as of June 30, 1997 and
for the six months ended June 30, 1996 and 1997 reflect, in the opinion of
management, all adjustments (which include only normal recurring adjustments)
necessary to fairly state the financial position and results of operations for
such periods. The condensed consolidated financial statements and accompanying
notes have also been restated to reflect acquisitions accounted for as
poolings-of-interests (See Note 2).

         Operating results for interim periods are not necessarily indicative of
the results for full years. It is suggested that these condensed consolidated
financial statements be read in conjunction with the consolidated financial
statements of Allied Waste Industries, Inc. and subsidiaries for the year ended
December 31, 1996 and the related notes thereto included in the Company's Annual
Report on Form 10-K filed with the SEC on March 27, 1997 and amended on August
8, 1997.

         There have been no significant additions to or changes in accounting
policies of the Company since December 31, 1996. For a description of these
policies, see Note 1 of Notes to Consolidated Financial Statements for the year
ended December 31, 1996 in the Company's Annual Report on Form 10-K.

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

FINANCIAL INSTRUMENTS

         In June 1997, the Company entered into an Amended and Restated Credit
Agreement (the "Credit Agreement") with Credit Suisse First Boston, as
administrative and collateral agent, Citibank, N.A. as documentation agent and
Goldman Sachs Credit Partners, LP, as syndication agent. The Credit Agreement
provides a six and one-half year senior secured $500 million term loan facility
(the "Term Loan Facility") and a six and one-half year senior secured $400
million revolving credit facility (the "Revolving Credit Facility" and together
with the Term Loan Facility, the "Senior Credit Facility"). Principal payments
on the Term Loan Facility are payable quarterly, beginning in September 1997 and
increase from $10 million to $100 million per annum through maturity in December
2003. Principal under the Revolving Credit Facility is due upon maturity.

<PAGE>   7
                          ALLIED WASTE INDUSTRIES, INC.
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         The Senior Credit Facility bears interest, at the Company's option, at
either (a) a Base Rate, or (b) a Eurodollar Rate, both terms as defined in the
Credit Agreement, plus, in either case, an agreed upon applicable margin. The
applicable margin will be adjusted from time to time pursuant to a pricing grid
based upon the Company's Leverage Ratio, as defined in the Credit Agreement, and
varies between zero percent and 0.75% for Base Rate loans, and 0.75% and 1.75%
for Eurodollar loans. In addition, if at any time the Company's Senior Debt
Ratio is greater than 2.5 to 1.0, the applicable margin for all loans will be
increased by 0.25%.

         The Credit Agreement contains certain financial covenants including,
but not limited to, a Total Debt to EBITDA ratio, a Senior Debt to EBITDA ratio,
a Fixed Charge Coverage ratio and an Interest Expense Coverage ratio, all terms
as defined in the Credit Agreement. In addition, the Credit Agreement also
limits the Company's ability to make acquisitions, purchase fixed assets above
certain amounts, pay dividends, incur additional indebtedness and liens, make
optional prepayments on certain subordinated indebtedness, make investments,
loans or advances, enter into certain transactions with affiliates or enter into
a merger, consolidation or sale of all or a substantial portion of the Company's
assets.

         The Company has entered into interest rate protection agreements (the
"Agreements"), with reputable national banks and investment banking institutions
to reduce its exposure to fluctuations in variable interest rates. A summary of
the Agreements outstanding as of June 30, 1997 is as follows:

<TABLE>
<CAPTION>
                     Notional Amount       Fixed Rate
                  (dollars in millions)
<S>                                        <C>
                         $  50                5.76%
                            50                5.81
                           130                6.27
</TABLE>

         The Agreements effectively change the Company's interest rate paid on
$230 million of its floating rate long-term debt ($576 million at June 30, 1997)
to a weighted average fixed rate ceiling of approximately 6.06% plus applicable
margins imposed by the terms of the Credit Agreement at June 30, 1997.

         As the Company utilizes the Agreements for hedging purposes, amounts
paid to obtain the Agreements, if any, are capitalized into deferred financing
charges in the accompanying consolidated balance sheets and amortized over the
life of the specific Agreement.

ACCOUNTING PRONOUNCEMENTS NOT YET REQUIRED TO BE ADOPTED

         In March 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128 "Earnings per Share" ("SFAS
No. 128"), which specifies the computation, presentation and disclosure
requirements for earnings per share. SFAS No. 128 is effective for periods
ending after December 15, 1997 and requires retroactive restatement of prior
periods earnings per share. The statement replaces the "primary earnings per
share" calculation with a "basic earnings per share" and redefines the "dilutive
earnings per share" computation. Management does not expect the adoption of the
statement to have a material effect on the Company's reported income per common
share.

EXTRAORDINARY LOSS, NET

         On May 15, 1997, the Company repurchased (the "Repurchase") from
Laidlaw Inc. ("Laidlaw") and Laidlaw Transportation, Inc. (collectively, the
"Laidlaw Group") for $230 million in cash, the $150 million 7% Junior
Subordinated Debenture ($81.6 million book value), the $168.3 million Zero
Coupon Debenture ($34.9 million book value, collectively the "Allied
Debentures") and the warrant to purchase 20.4 million shares of common stock
($49.0 million book value, the "Warrant"), issued as partial consideration for
the purchase of Laidlaw's solid waste business in 1996 (the "Laidlaw
Acquisition"). An extraordinary charge of approximately $65.7 million ($39.4
million net of income tax benefit) related to the Repurchase was recorded in the
second quarter of 1997. In addition, on June 5, 1997, the Company replaced its
1996 Bank Agreement (as defined herein) with the Senior Credit Facility and 
recognized an extraordinary charge of approximately $21.6 million 
($13.0 million net of income tax benefit) related to prepayment penalties and 
the write off of previous deferred debt issuance costs in the second quarter 
of 1997.

2. BUSINESS COMBINATIONS AND DIVESTITURES

         Acquisitions accounted for as purchases are reflected in the results of
operations since the date of purchase in Allied's condensed consolidated
financial statements. The results of operations for acquisitions accounted for
as poolings-of-interests are included in Allied's condensed consolidated
financial statements for all periods presented. Often, the final determination
of the cost, and the allocation thereof, of certain of the Company's
acquisitions is subject to resolution of certain contingencies. Once such
contingencies are achieved, the purchase price is adjusted. Shares issued in
connection with business acquisitions have been valued taking into consideration
certain restrictions placed on the stock.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         In April 1997, the Company completed the sale of certain non-core
medical waste assets for approximately $6.7 million. In addition, the Company
sold five collection operations, one recycling facility and one landfill to USA
Waste and Browning-Ferris Industries ("BFI") during the second quarter of 1997
for approximately $68.4 million. No gain or loss was recorded in connection with
these sales.

         The following table summarizes acquisitions for the six months ended
June 30, 1996 and 1997. In May 1997, the Company acquired a collection company
in a transaction accounted for as a pooling-of-interests. As the effect of this
business combination was not significant, prior period financial statements were
not restated to include historical operating results of the acquired company.

UNAUDITED PRO FORMA INCOME STATEMENT DATA

         The following unaudited pro forma consolidated data for the year ended
December 31, 1996 and the six months ended June 30, 1997 presents the results of
operations of Allied as if the companies acquired using the purchase method of
accounting for business combinations in 1996 and through June 30, 1997 (giving
effect to the Canadian Sale), had all occurred as of January 1, 1996 (in
thousands, except per share data). This data does not purport to be indicative
of the results of operations of Allied that might have occurred nor which might
occur in the future.

4. NET INCOME (LOSS) PER COMMON SHARE

         Net income (loss) per common share is calculated by dividing net income
(loss) less dividend requirements on preferred stock by the weighted average
number of common shares and common share equivalents outstanding during each
period, as restated to reflect acquisitions accounted for as
poolings-of-interests. The computation of weighted average common and common
equivalent shares used in the calculation of net income (loss) per common share
is as follows (unaudited):

6.  SUBSEQUENT EVENTS

         Subsequent to June 30, 1997, the Company completed the acquisition of 4
privately-held solid waste companies representing approximately $2.9 million in
annual revenue. Total consideration of approximately $3.3 million, comprised of
cash, notes and Common Stock, was paid in the separate transactions.

         Subsequent to June 30, 1997, all of the 7% preferred stock outstanding
was converted into 1,356,573 shares of Common Stock and approximately $755,000
of convertible debt was converted into 75,494 shares of Common Stock in
accordance with the original terms of each of the agreements.

         On August 12, 1997, the Company executed a definitive agreement to
assume ownership and operation of the solid waste disposal system for San Diego
County, California. The completion of this transaction is subject to normal
regulatory approvals, the transfer of operating permits and certain other
conditions. Allied will purchase four landfills, one transfer station, and one
material recovery facility for $160 million in cash paid directly to San Diego
County, and make certain agreed upon future capital expenditures for
approximately $24 million. Completion of this transaction is expected to occur
before December 31, 1997.

                        MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
Company's Condensed Consolidated Financial Statements and the notes thereto,
included elsewhere herein.

INTRODUCTION

         The Company has experienced significant growth, a substantial portion
of which has resulted from the acquisition of solid waste businesses. Since
January 1, 1992, the Company has completed 112 acquisitions including the
Laidlaw Acquisition (as described below). In 1996, the Company acquired
22 businesses including the Laidlaw Acquisition and subsequent to 1996
it has acquired 15 businesses, excluding the assets acquired in the USA
Waste transactions (see below). See Note 2 to the Company's Consolidated
Financial Statements. The Company's Consolidated Financial Statements
have been restated to reflect the acquisition of companies accounted
for using the pooling-of-interests method for business combinations. The
majority of the acquisitions were accounted for under the purchase method for
business combinations and, accordingly, the results of operations for such
acquired businesses are included in the Company's financial statements only from
the applicable date of acquisition. As a result, the Company believes its
historical results of operations for the periods presented are not directly
comparable.

         On December 30, 1996, the Company completed the acquisition  (the
"Laidlaw Acquisition") of substantially all of the non-hazardous solid waste
management business conducted by Laidlaw Inc. ("Laidlaw") in the United States
and Canada, for total consideration of approximately $1.5 billion comprised of
$1.2 billion cash, 14.6 million shares of Common Stock, a warrant (the
"Warrant") to acquire 20.4 million shares of the Company's Common Stock, par
value $0.01 per share (the "Common Stock"), and two junior subordinated
debentures with an aggregate face amount of $318.3 million comprised of a $150
million 7% Junior Subordinated Debenture and a $168.3 million Zero Coupon
Debenture (collectively, the "Allied Debentures"). The cash consideration was
financed from the proceeds of the 1996 Bank Agreement and the sale of the
1996 Notes.

         On March 16, 1997, pursuant to a share purchase agreement with USA
Waste Services, Inc. ("USA Waste"), the Company sold to USA Waste all of the
Canadian non-hazardous solid waste management operations of the Company for
approximately $518 million (the "Canadian Sale"). The Company used the proceeds
from the Canadian Sale to pay down approximately $517 million in debt under the
1996 Bank Agreement. The Company acquired the Canadian operations in connection
with the Laidlaw Acquisition.

         On May 15, 1997, the Company, pursuant to a Securities Purchase
Agreement (the "Laidlaw Securities Purchase Agreement") with Laidlaw and Laidlaw
Transportation, Inc. (collectively, the "Laidlaw Group") and certain private
securities investment funds affiliated with either (i) Apollo Advisors II, L.P.
or (ii) the Blackstone Group, repurchased from the Laidlaw Group the Allied
Debentures and the Warrant for an aggregate purchase price of $230 million in
cash (the "Repurchase"). The net proceeds of $240 million related to the $418
million face value 11.3% senior discount notes, (the "Senior Discount Notes") 
were used to fund the Repurchase. The offering of the Senior Discount Notes 
closed on May 15, 1997. Also pursuant to the Laidlaw Securities Purchase 
Agreement, the private securities investment funds purchased all of the Common 
Stock of Allied held by Laidlaw.

         In June 1997, the Company entered into an Amended and Restated Credit
Agreement (the "Credit Agreement") with Credit Suisse First Boston, an
administrative and collateral agent, Citibank, N.A. as documentation agent and
Goldman Sachs Credit Partners, LP, as syndication agent. The Credit Agreement
provides a six and one-half year senior secured $500 million term loan facility
(the "Term Loan Facility") and a six and one-half year senior secured $400
million revolving credit facility (the "Revolving Credit Facility" and together
with the Term Loan Facility, the "Senior Credit Facility").

                                       13
<PAGE>   14

         On June 12, 1997, the Company completed a series of transactions with
USA Waste (the "USA Waste Transactions") pursuant to which the Company acquired
eight landfills (two of which were consummated in July 1997 after completion of
certain permitting and regulatory matters), eight collection operations, five
transfer stations and one recycling facility with an annual aggregate revenue of
$58.0 million for consideration of $87.5 million. Also pursuant to the USA Waste
Transactions, the Company sold to USA Waste one landfill, two collection
operations and one recycling facility with an aggregate of approximately $33.6
million in annual revenue for which it received consideration of approximately
$61.3 million.

GENERAL

         Revenues. The Company's revenues are attributable primarily to fees
charged to customers for waste collection, transfer, recycling and disposal
services. The Company's collection services are generally provided under direct
agreements with its customers or pursuant to contracts with municipalities.
Commercial and municipal contract terms, where used, generally range from 1 to 5
years and commonly have automatic renewal options. The Company's landfill
operations include both Company-owned landfills and those operated for
municipalities for a fee. The Company is fully integrated in each geographic
region in which it is located as it provides collection, transfer and disposal
services. The tables below show for the periods indicated the percentage of the
Company's total reported revenues attributable to services provided and to
geographic region:

- ---------

(1)      The portion of collection and third-party transfer revenues
         attributable to disposal charges for waste collected by the Company and
         disposed at the Company's landfills have been excluded from collection
         and transfer revenues and included in landfill revenues.

         The Company's strategy is to develop vertically integrated operations
to ensure internalization of waste it collects and thus realize higher margins
from its operations. By disposing of waste at Company-owned and/or operated
landfills, the Company retains the margin generated through disposal operations
that would otherwise be earned by third-party landfills. Approximately 57% of
Company-collected waste is disposed of at Company-owned and/or operated
landfills as measured using disposal costs in the first six months of 1997. In
addition, transfer stations are an integral part of the disposal process. The
Company locates its transfer stations in areas where its landfills are outside
of the population centers in which it collects waste. Such waste is transferred
to long-haul trailers and economically transported to its landfills.

         Expenses. Cost of operations includes labor, maintenance and repairs,
equipment and facility rent, utilities and taxes, the costs of ongoing
environmental compliance, safety and insurance, disposal costs and costs of
independent haulers transporting Company waste to the disposal site. Disposal
costs include certain landfill taxes, host community fees, payments under
agreements with respect to landfill sites that are not owned, landfill site
maintenance, fuel and other equipment operating expenses and accruals for
estimated closure and post-closure monitoring expenses anticipated to be
incurred in the future.

         Selling, general and administrative expenses include management,
clerical and administrative compensation and overhead, sales costs, community
relations expenses and provisions for estimated uncollectible accounts
receivable and potentially unrealizable acquisition costs.

         Depreciation and amortization expense includes depreciation of fixed
assets and amortization of landfill airspace, goodwill and other intangible
assets.

         In connection with potential acquisitions, the Company incurs and
capitalizes certain transaction and integration costs which include stock
registration, legal, accounting, consulting, engineering and other direct costs.
When an acquisition is completed and is accounted for using the
pooling-of-interests method for business combinations, these costs are charged
to the statement of operations as acquisition related costs. When a completed
acquisition is accounted for using the purchase method for business
combinations, these costs are capitalized. The Company routinely evaluates
capitalized transaction and integration costs and expenses those costs related
to acquisitions not likely to occur. Indirect acquisition costs, such as
executive salaries, general corporate overhead and other corporate services, are
expensed as incurred.

         Certain direct landfill development costs, such as engineering,
upgrading, construction and permitting costs, are capitalized and amortized
based on consumed airspace. The Company believes that the costs associated with
engineering, owning and operating landfills will increase in the future as a
result of federal, state and local regulation and a growing community awareness
of the landfill permitting process. Although there can be no assurance, the
Company believes that it will be able to implement price increases sufficient to
offset these increased expenses. All indirect landfill development costs, such
as executive salaries, general corporate overhead, public affairs and other
corporate services, are expensed as incurred.

         Accrued closure and post-closure costs represent an estimate of the
current value of the future obligation associated with closure and post-closure
monitoring of non-hazardous solid waste landfills currently owned and/or
operated by the Company. Site specific closure and post-closure engineering cost
estimates are prepared annually for landfills owned and/or operated by the
Company for which it is responsible for closure and post-closure. The present
value of estimated future costs are accrued based on accepted tonnage as
landfill airspace is consumed. Discounting of future costs is applied where the
Company believes that both the amounts and timing of related payments are
reliably determinable. The Company periodically updates its estimates of future
closure and post-closure costs. The impact of changes which are determined to be
changes in estimates are accounted for on a prospective basis.

         Currently, the net present value of the closure and post-closure
commitment is calculated assuming inflation of 2.5% and a risk-free capital rate
of 7.0%. Discounted amounts previously recorded are accreted to reflect the
effects of the passage of time. The Company's current estimate of total future
payments for closure and post-closure is $623.6 million while the present value
of such estimate is $190.5 million. At December 31, 1996 and June 30, 1997,
accruals for landfill closure and post-closure costs (including costs assumed
through acquisitions) were approximately $107.5 million and $109.7 million. The
accruals reflect relatively young landfills with estimated remaining lives,
based on current waste flows, that range from 1 to over 75 years, and an
estimated average remaining life of greater than 30 years.

         Revenues. Revenues in 1997 were $211.1 million compared to $62.0
million in 1996, an increase of 240.4%. Revenues of approximately $143.0 million
in the second quarter of 1997 were generated from companies acquired subsequent
to March 1996, while increases in revenues attributable to existing operations
("Internal Growth") amounted to $6.1 million. If the Laidlaw Acquisition, net of
the Canadian Sale, is included as of March 1996, Internal Growth would have
approximated 11% with 7% attributable to net volume increases and 4%
attributable to price increases.

         Cost of Operations. Cost of operations in 1997 was $113.4 million
compared to $33.8 million in 1996, an increase of 235.0%. The increase in cost
of operations was primarily attributable to the increase in revenues described
above. As a percentage of revenues, cost of operations decreased to 53.7% in
1997 from 54.6% in 1996. Operating cost margins were favorably impacted by
financial benefits and operational efficiencies associated with the Laidlaw
Acquisition and the significant increase in revenues.

         Selling, General and Administrative Expenses. SG&A expenses increased
to $23.9 million in 1997 compared to $8.8 million in 1996, an increase of
172.0%. As a percentage of revenues, SG&A decreased to 11.3% in 1997 compared to
14.1% in 1996. The increase in SG&A expense resulted from expenses associated
with acquired companies and expenses incurred in connection with the Company's
increase in personnel and other expenses related to the growth of the Company.
The decrease in SG&A as a percentage of revenues can be attributed to the
substantial increase in the revenues of the Company resulting principally from
the Laidlaw Acquisition while SG&A expenses of the combined companies were 
significantly reduced.

<PAGE>   17
         Depreciation and amortization. Depreciation and amortization in 1997
was $27.3 million compared to $8.0 million in 1996, an increase of 241.4%. The
increase in depreciation and amortization expense is due to acquisitions and
capital expenditures. As a percentage of revenues, depreciation and amortization
has remained constant at 12.9%.

         Acquisition related costs. Costs of $5.8 million were incurred in 1996
for transaction and integration costs directly related to acquisitions accounted
for using the pooling-of-interests method for business combinations. Transaction
costs include stock registration, legal, accounting, consulting, engineering and
other direct third-party costs incurred to complete the acquisitions.
Integration costs include uncollectible accounts receivable write-offs, employee
termination and relocation, write down of fixed assets, lease termination, and
deferred repairs and maintenance of vehicles and equipment. During the second
quarter of 1997, no material acquisition related costs were incurred.

         Net interest expense. Net interest expense was $24.3 million in 1997
compared to $2.5 million in 1996, an increase of 883.1%. The increase in
interest expense is due to the increase in debt from $205.7 million at June 30,
1996 compared to $1.4 billion at June 30, 1997. This increase in debt
outstanding is primarily the result of debt incurred in connection with the
Laidlaw Acquisition net of the application of the net proceeds received in
connection with the Canadian Sale.

         Income taxes. Income taxes reflect a 43% effective income tax rate in
1997 as compared to a 55% rate in 1996. The Company's effective tax rate in 1997
and 1996 deviates from the federal statutory rate of 35%, due primarily to the
effects of differences in the treatment of goodwill for book and tax purposes,
state income taxes, and other permanent differences.

         Extraordinary loss, net. On May 15, 1997, the Company repurchased from
the Laidlaw Group the Allied Debentures and the Warrant, used as partial
consideration for the Laidlaw Acquisition, for an aggregate purchase price of
$230 million in cash. An extraordinary charge to earnings related to the
Repurchase of approximately $65.7 million ($39.4 million net of income tax
benefit) was recorded in the second quarter of 1997. In addition, the Company
replaced its $1.275 billion senior credit facility (the "Bank Agreement") with
the $900 million Senior Credit Facility on June 5, 1997 and recognized an
extraordinary charge of approximately $21.6 million ($13.0 million net of income
tax benefit) in the second quarter of 1997.

         Revenues. Revenues in 1997 were $395.2 million compared to $119.0
million in 1996, an increase of 232.2%. Revenues of approximately $265.4 million
in the first six months of 1997 were generated from companies acquired
subsequent to December 1995, while increases in revenues attributable to
existing operations amounted to $10.8 million. If the Laidlaw Acquisition, net
of the Canadian Sale, is included as of March 1996, Internal Growth would have
approximated 9% with 5% attributable to net volume increases and 4% attributable
to price increases..

         Cost of Operations. Cost of operations in 1997 was $218.3 million
compared to $65.7 million in 1996, an increase of 232.2%. The increase in cost
of operations was primarily attributable to the increase in revenues described
above. As a percentage of revenues, cost of operations remained constant at
55.2%. Operating cost margins were favorably impacted by financial benefits and
operational efficiencies associated with the Laidlaw Acquisition and the
significant increase in revenues.

         Selling, General and Administrative Expenses. SG&A expenses increased
to $46.5 million in 1997 compared to $18.5 million in 1996, an increase of
151.9%. As a percentage of revenues, SG&A decreased to 11.8% in 1997 compared to
15.5% in 1996. The increase in SG&A expense resulted from expenses associated
with acquired companies and expenses incurred in connection with the Company's
increase in personnel and other expenses related to the growth of the Company.
The decrease in SG&A as a percentage of revenues can be attributed to the
substantial increase in the revenues of the Company resulting principally from
the Laidlaw Acquisition while SG&A expenses of the combined companies were
significantly reduced.

         Depreciation and amortization. Depreciation and amortization in 1997 
was $52.2 million compared to $15.4 million in 1996, an increase of 238.5%. The
increase in depreciation and amortization expense is due to acquisitions and
capital expenditures. Fixed assets have increased from $414.3 million at June
30, 1996 to $1,004.9 million at June 30, 1997 and goodwill has increased from
$98.0 million at June 30, 1996 to $877.6 million at June 30, 1997. As a
percentage of revenues, depreciation and amortization increased to 13.2% in 1997
from 13.0% in 1996. This is primarily the result of an increase in amortization
of goodwill as a percentage of revenues to 2.8% in 1997 from 1.9% in 1996
partially offset by a decrease in landfill amortization as a percentage of
revenues to 2.7% in 1997 from 3.2% in 1996 related to increased goodwill and
decreased internalization in connection with the Laidlaw Acquisition.

         Acquisition related costs. Costs of $6.7 million were incurred in 1996
transaction and integration costs directly related to acquisitions accounted for
using the pooling-of-interests method for business combinations. Transaction
costs include stock registration, legal, accounting, consulting, engineering and
other direct third-party costs incurred to complete the acquisitions.
Integration costs include uncollectible accounts receivable write-offs, employee
termination and relocation, write down of fixed assets, lease termination, and
deferred repairs and maintenance of vehicles and equipment. During the first six
months of 1997, no material acquisition related costs were incurred.

         Net interest expense. Net interest expense was $45.6 million in 1997
compared to $4.4 million in 1996, an increase of 930.6%. The increase in
interest expense is due to the increase in debt from $205.7 million at June 30,
1996 compared to $1.4 billion at June 30, 1997. This increase in debt
outstanding is primarily the result of debt incurred in connection with the
Laidlaw Acquisition net of the application of the net proceeds received in
connection with the Canadian Sale.

         Income taxes. Income taxes reflect a 43% effective income tax rate in
1997 as compared to a 49% rate in 1996. The Company's effective tax rate in 1997
and 1996 deviates from the federal statutory rate of 35%, due primarily to the
effects of differences in the treatment of goodwill for book and tax purposes,
state income taxes, and other permanent differences.

         Extraordinary loss, net. On May 15, 1997, the Company repurchased from
the Laidlaw Group the $150 million 7% Junior Subordinated Debenture, the $168.3
million Zero Coupon Debenture and a warrant to purchase 20.4 million shares of
common stock, used as partial consideration for the purchase of Laidlaw's solid
waste business in 1996, for an aggregate purchase price of $230 million in cash.
An extraordinary charge related to the Repurchase of approximately $65.7 million
($39.4 million net of income tax benefit) was charged to earnings in the second
quarter of 1997. In addition, the Company replaced its $1.275 billion Bank
Agreement with the $900 million Senior Credit Facility on June 5, 1997 and
recognized an extraordinary charge of approximately $21.6 million ($13.0 million
net of income tax benefit) in the second quarter of 1997.

LIQUIDITY AND CAPITAL RESOURCES

         Historically, the Company has satisfied its acquisition, capital
expenditure and working capital needs primarily through bank financing, public
offerings and private placements of debt and equity securities. Between January
1, 1994 and June 30, 1997, the Company completed the $900 million Senior Credit
Facility which replaced the $1.275 billion Bank Agreement completed in
connection with the Laidlaw Acquisition (of which $517 million was repaid with
proceeds from the Canadian Sale in March 1997), a $418 million private placement
of its 11.3% senior discount notes, a $525 million private placement of the 1996
Notes, a $100 million public offering of its $100 million 12% Senior
Subordinated Notes due 2004 (the "1994 Notes") (substantially all of which were
repurchased pursuant to a tender offer (the "Tender Offer") in July 1996), a $50
million private placement of Common Stock, a $300 million senior revolving
credit facility (all debt under which was repaid in December 1996), and a $48
million public equity offering. Because of the capital intensive nature of the
solid waste industry and companies that grow substantially through acquisition,
the Company has used, and believes that it is reasonably possible that it will
continue using amounts in excess of the cash generated from operations to fund
acquisitions and capital expenditures, including landfill development. In
connection with acquisitions, the Company has assumed or incurred indebtedness
with relatively short-term repayment schedules, thereby increasing its current
and medium-term liabilities. Additionally, operating equipment has been acquired
using financing leases which have short and medium-term maturities. As a result,
the Company has periodically had low levels of working capital or working
capital deficits.

(1)      Consists principally of provisions for depreciation and amortization,
         landfill closure and post-closure costs, doubtful accounts, potentially
         unrealizable acquisition costs and deferred income taxes.

         As of June 30, 1997, the Company had cash and cash equivalents of $14.6
million. The Company's capital expenditure and working capital requirements have
increased significantly, reflecting the Company's rapid growth by acquisition
and development of revenue producing assets, and will increase further as the
Company continues to pursue its business strategy. During 1996 the Company
completed the Laidlaw Acquisition for total consideration of approximately $1.5
billion consisting of $1.2 billion cash, 14.6 million shares of Common Stock,
the Warrant to acquire 20.4 million shares of Common Stock, and the Allied
Debentures with an aggregate face amount of $318.3 million and acquired 21
additional businesses for total consideration of approximately $126.5 million of
which approximately $73.9 million of such consideration was paid in Common Stock
and $3.9 million was paid in seller notes. Total annualized revenues of the
latter businesses are approximately $78.8 million. Since January 1, 1997, the
Company has acquired solid waste operations, representing approximately $142.8
million in annual revenues and sold operations representing approximately $46.5
million in annual revenue. Net consideration of approximately $165.1 million
(including $10 million for the landfill under development) comprised of cash,
notes and Common Stock, was paid in these transactions. For the calendar year
1997, the Company expects to spend approximately $172 million for capital,
closure and post-closure, and remediation expenditures relating to its landfill
operations. As the Company continues to acquire waste operations in 1997,
additional capital amounts will be required during 1997 for the acquisition of
businesses and the capital expenditure requirements related to those acquired
businesses.

                                       20
<PAGE>   21
         On June 30, 1997, the Company's debt structure consisted of $525
million of the 1996 Notes, $500 million outstanding under the Term Loan
Facility, approximately $76 million outstanding under the Revolving Credit
Facility, and approximately $240 million of the Senior Discount Notes. As of
June 30, 1997 there is aggregate availability under the Revolving Credit
Facility of approximately $256 million to be used for working capital, letters
of credit, acquisitions and other general corporate purposes. No more than $175
million of the Revolving Credit Facility may be used to support the issuance of
letters of credit. The indenture relating to the 1996 Notes and the Senior
Credit Facility contain financial and operating covenants and significant
restrictions on the ability of the Company to complete acquisitions, pay
dividends, incur indebtedness, make investments and take certain other corporate
actions. A substantial portion of the Company's available cash will be required
to be applied to service indebtedness and preferred stock obligations, including
indebtedness incurred to finance the Laidlaw Acquisition, which is expected to
include approximately $203.6 million in annual principal and interest payments
(after giving effect to the payment of $517 million on the 1996 Bank Agreement
from the Canadian sale).

         The Company is also required to provide financial assurances to
governmental agencies under applicable environmental regulations relating to its
landfill operations and collection contracts. These financial assurance
requirements are satisfied by the Company issuing performance bonds, letters of
credit, insurance policies and trust deposits to secure the Company's
obligations as they relate to landfill closure and post-closure costs and
performance under certain collection contracts. At June 30, 1997, the Company
had outstanding approximately $264.6 million in financial assurance instruments,
represented by $180.1 million of performance bonds, $22.3 million of letters of
credit, $55.9 million of insurance policies and $6.3 million of trust deposits.
During calendar year 1997, the Company expects to be required to provide
approximately $258 million in financial assurance obligations relating to its
landfill operations and collection contracts. The Company expects that financial
assurance obligations will increase in the future as it acquires and expands its
landfill activities and that a greater percentage of the financial assurance
instruments will be comprised of performance bonds and insurance policies.

         The Company has lease facilities (the "Lease Facilities") that allow it
to enter into equipment leases at rates ranging from similar term treasury note
rates plus 2.5% to 3.5% for terms of 36 to 84 months. In addition to equipment
leases outstanding at December 31, 1996 and June 30, 1997 of $45.2 million and
$74.2 million, respectively, the Company had available lease commitments of
$11.9 million and $22.4 million, respectively. The Company has entered into
master equipment lease facilities relating to the financing of the acquisition
of trucks and containers.

         On August 12, 1997, the Company executed a definitive agreement to
assume ownership and operation of the solid waste disposal system for San Diego
County, California. The completion of this transaction is subject to certain
normal regulation approvals, the transfer of operating permits and certain other
conditions. Allied will purchase four landfills, one transfer station, and one
material recovery facility for $160 million in cash paid directly to San Diego
County, and make certain agreed upon future capital expenditures for
approximately $24 million. Completion of this transaction is expected to occur
before December 31, 1997.

         The Company expects that Subtitle D and other regulations that apply to
the non-hazardous waste disposal industry will require the Company, as well as
others in the industry, to alter operations and to modify or replace existing
facilities. Such expenditures have been and will continue to be substantial.
Further regulatory changes could accelerate expenditures for closure and
post-closure monitoring and obligate the Company to spend sums in addition to
those presently reserved for such purposes. These factors, together with the
other factors discussed above, could substantially increase the Company's
operating costs and impair the Company's ability to invest in its facilities.

                                       21
<PAGE>   22
         The Company's ability to meet future capital expenditure and working
capital requirements, to make scheduled payments of principal of, to pay
interest on, or to refinance its indebtedness, and to fund capital amounts
required for the acquisition of businesses and the expansion of existing
businesses depends on its future performance, which, to a certain extent, is
subject to general economic, financial, competitive, legislative, regulatory and
other factors beyond its control. One of the primary factors impacting the
Company's future performance will be its ability to integrate the assets
acquired in the Laidlaw Acquisition after the Canadian Sale, and to reduce
redundancies and excess costs. These operations are significantly larger than
the Company's previous operations and represent a substantial increase in the
scope of the Company's business. Based upon the current level of operations and
anticipated growth, management of the Company believes that available cash flow,
together with available borrowing under the Senior Credit Facility, the Lease
Facilities and other sources of liquidity, will be adequate to meet the
Company's anticipated future requirements for working capital,
letters-of-credit, capital expenditures, scheduled payments of principal of and
interest on debt incurred under the Senior Credit Facility, interest on the 1996
Notes and the Senior Discount Notes, and capital amounts required for
acquisitions and expansion. However, the principal payment at maturity on the
1996 Notes and the Senior Discount Notes may require refinancing. Also there can
be no assurance that the Company's business will generate sufficient cash flow
from operations or that future financings will be available in an amount
sufficient to enable the Company to service its indebtedness or to make
necessary capital expenditures, or that any refinancing would be available on
commercially reasonable terms if at all. Additionally, depending on the timing,
amount and structure of any future acquisitions and the availability of funds
under the acquisition facility under the Senior Credit Facility, the Company may
need to raise additional capital to fund the acquisition and integration of
additional solid waste businesses. The Company may raise such funds through
additional bank financings or public or private offerings of its debt and equity
securities. There can be no assurance that the Company will be able to secure
such funding, if necessary, on favorable terms, if at all. If the Company is not
successful in securing such funding, the Company's ability to pursue its
business strategy may be impaired and results of operations for future periods
may be negatively affected.

SIGNIFICANT FINANCING EVENTS

         In December 1996, the Company entered into a bank credit facility
(the "1996 Bank Agreement") consisting of (i) a $475 million five and one-half
year amortizing senior secured term loan facility, (ii) three amortizing
senior secured term loan facilities in an aggregate original principal amount
of $500 million and with ultimate maturities which ranged from six and
one-half years to eight and one-half years, and (iii) a $300 million five and
one-half year senior secured revolving credit facility. In connection with
the closing of the Canadian Sale, an aggregate amount of approximately $517
million was applied to prepayment of the 1996 Bank Agreement.

         In June 1997, the Company entered into the Credit Agreement with Credit
Suisse First Boston, as administrative and collateral agent, Citibank, N.A. as
documentation agent and Goldman Sachs Credit Partners, LP, as syndication agent.
The Credit Agreement provides a six and one-half year senior secured $500
million Term Loan Facility and a six and one-half year senior secured $400
million Revolving Credit Facility. Principal payments on the Term Loan
Facility are payable quarterly, beginning in September 1997 and increase from
$10 million to $100 million per annum through maturity in December 2003.
Principal under the Revolving Credit Facility is due upon maturity.

         In addition to the scheduled principal payments above, the Company is
also required to make mandatory prepayments on the Senior Credit Facility equal
to 100% of the net proceeds from certain asset sales, the issuance of new debt
securities and extraordinary amounts, which include tax refunds, pension plan
reversions and certain insurance proceeds, and 50% of the net proceeds from new
equity issuances. Furthermore, the Company is also required to make mandatory
prepayments on the Senior Credit Facility equal to 50% of the Company's annual
excess Cash Flow, as defined in the Credit Agreement, unless the Company's
Senior Debt Ratio, as defined in the Credit Agreement, for the relevant fiscal
year end is less than 2.0 to 1.0. Mandatory prepayments are applied first to the
Term Loan Facility on a pro rata basis against remaining scheduled principal
payments, and second; to the permanent reduction of the Revolving Credit
Facility.

                                       22
<PAGE>   23
In no event, however, shall the Revolving Credit Facility be required to be
reduced to an amount less than $300 million in connection with any such
mandatory prepayment.

         Borrowings under the Revolving Credit Facility may be used for
acquisitions, the issuance of letters of credit, working capital and other
general corporate purposes. Of the $400 million available under the Revolving
Credit Facility, no more than $175 million may be used to support the issuance
of letters of credit.

         The Senior Credit Facility bears interest, at the Company's option, at
either (a) a Base Rate, or (b) a Eurodollar Rate, both terms as defined in the
Credit Agreement, plus, in either case, an agreed upon applicable margin. The
applicable margin will be adjusted from time to time pursuant to a pricing grid
based upon the Company's Leverage Ratio, as defined in the Credit Agreement, and
varies between zero percent and 0.75% for Base Rate loans, and 0.75% and 1.75%
for Eurodollar loans. In addition, if any time, the Company's Senior Debt Ratio
is greater than 2.5 to 1.0, the applicable margin for all loans will be
increased by 0.25%.

         The Senior Credit Facility is guaranteed by substantially all of the
Company's present and future subsidiaries. In addition, the Senior Credit
Facility is secured by substantially all the personal property and a pledge of
the stock, of substantially all the Company's present and future subsidiaries.

         The Credit Agreement contains certain financial covenants including,
but not limited to, a Total Debt to EBITDA ratio, a Senior Debt to EBITDA ratio,
a Fixed Charge Coverage ratio and an Interest Expense Coverage ratio, all terms
as defined in the Credit Agreement. In addition, the Credit Agreement also
limits the Company's ability to make acquisitions, purchase fixed assets above
certain amounts, pay dividends, incur additional indebtedness and liens, make
optional prepayments on certain subordinated indebtedness, make investments,
loans or advances, enter into certain transactions with affiliates or enter into
a merger, consolidation or sale of all or a substantial portion of the Company's
assets.

         The Company has entered into interest rate protection agreements (the
"Agreements"), with reputable national banks and investment banking institutions
to reduce its exposure to fluctuations in variable interest rates. A summary of
the Agreements outstanding as of June 30, 1997 is as follows:

<TABLE>
<CAPTION>
                          Notional Amount      Fixed Rate
                       ---------------------   ----------
                       (dollars in millions)
<S>                                            <C>
                              $  50                5.76%
                                 50                5.81
                                130                6.27
</TABLE>

         The Agreements effectively change the Company's interest rate paid on
$230 million of its floating rate long-term debt ($576 million at June 30, 1997)
to a weighted average fixed rate ceiling of approximately 6.06% plus applicable
margins imposed by the terms of the Credit Agreement at June 30, 1997.

         In December 1996, Allied NA issued $525 million of 10.25% Senior
Subordinated Notes due 2006 in a Rule 144A private offering (the "1996 Notes").
Net proceeds from the sale of the 1996 Notes, after the underwriting discount
and other expenses, were approximately $509 million. The net proceeds were used
to pay a portion of the cash purchase price of the Laidlaw Acquisition, repay
amounts outstanding under the Company's previous $300 million credit facility
with Credit Suisse as agent, fund certain acquisitions and for general corporate
purposes. Allied NA had an obligation to offer fully registered securities,
pursuant to an exchange offer, that are substantially identical to the 1996
Notes. Allied NA completed this exchange offer on July 23, 1997. The 1996 Notes
cannot be redeemed until December 1, 2001, except under certain circumstances.
Prior to December 1, 2001, the 1996 Notes are subject to redemption, at the
option of Allied NA, at the greater of (i) 100% of the principal amount of (ii)
the sum of the present values of the remaining scheduled payments of principal
and interest thereon discounted to maturity on a semiannual basis at a
comparable treasury yield plus 75 basis points, plus in each case accrued and
unpaid interest to the date of redemption. At any time prior to December 1,
1999, up to 33% of principal amount of 1996 Notes

                                       23
<PAGE>   24
will be redeemable, at the option of Allied NA, from the proceeds of one or more
public offerings of capital stock by the Company at a redemption price of
110.25% of principal amount, plus accrued interest. The 1996 Notes are
guaranteed by the Company and substantially all of Allied NA's subsidiaries, the
guarantees of which are expressly subordinated to the guarantees of Allied NA's
Senior Credit Facility. The 1996 Notes contain several covenants, the most
restrictive of which limits Allied NA and its subsidiaries' ability to incur
additional indebtedness without complying with an interest coverage ratio test.
Other covenants contain limitations on payment of dividends, issuance of
redeemable preferred stock, transactions with affiliates, granting of liens and
security interests, sales of assets and the use of proceeds from sales of
assets, mergers and consolidations, and changes of control. The covenants do
permit Allied NA to incur certain indebtedness including the Senior Credit
Facility, indebtedness issued and/or assumed in permitted acquisitions and other
indebtedness which is limited to a certain percentage of Allied NA's total
assets.

         On May 15, 1997, the Company, pursuant to (the Laidlaw Securities
Purchase Agreement) with the Laidlaw Group and certain private securities
investment funds affiliated with either (i) Apollo Advisors II, L.P. or (ii) the
Blackstone Group, repurchased from the Laidlaw Group the Allied Debentures and
the Warrant for an aggregate purchase price of $230 million in cash. The net
proceeds of the Offering of the Senior Discount Notes which also closed on May
15, 1997, have been used to fund the Repurchase. Also pursuant to the Laidlaw
Securities Purchase Agreement, the private securities investment funds purchased
all of the Common Stock of Allied held by Laidlaw.

         In connection with the Laidlaw Acquisition, the Company issued a
warrant to Laidlaw for the purchase of 20.4 million shares of common stock of
the Company at an exercise price of $8.25 per share (the "Warrant"). The Warrant
was retired in connection with the Repurchase on May 15, 1997.

         In January 1994, the Company issued $100 million of 10 3/4% senior
subordinated notes (the "1994 Notes"). The net proceeds from the sale of the
1994 Notes after underwriting discount and other expenses, were approximately
$95 million. In July 1996, the Company completed the Tender Offer and purchased
substantially all of its 1994 Notes at the redemption price of $1,157.50 per
$1,000 principal amount. In connection with the Tender Offer, the Company
recognized an extraordinary charge of $18.4 million ($11.0 million net of income
tax benefit), in the third quarter of 1996. The Company also received a consent
from a majority of the holders of the 1994 Notes to eliminate all substantive
financial covenants associated with the remaining 1994 Notes.

         Simultaneously with the Tender Offer in July 1996, the Company
completed a new $300 million revolving credit facility which was extinguished on
December 30, 1996 in connection with the financing of the Laidlaw Acquisition.
The Company recognized an extraordinary charge of $4.0 million ($2.4 million net
of income tax benefit), in the fourth quarter.

         On January 24, 1996, the Company completed a public offering of its
Common Stock. It issued 7.6 million shares for approximately $48 million net of
$5.2 million in underwriter discounts, commissions and offering costs. The net
proceeds from the offering were used to repay amounts outstanding under the
Company's outstanding credit agreement and for other general corporate purposes.

         During 1995, the Company offered to holders of all of its Series D, 9%
and $90 convertible preferred stock and its 6% Convertible Subordinated notes an
inducement to exercise their conversion option to receive Allied Common Stock.
The inducement consisted of the payment of dividends and interest that the
holders of these securities would have received from the date of conversion
through the first call or redemption date of each security. In total, 7,757,056
shares of Common Stock were issued upon conversion. Substantially all of the
Series D preferred stock and 6% Convertible Subordinated notes were converted,
all but 5,029 shares of the 9% preferred stock was converted and all of the $90
preferred stock was converted. Accordingly, the Company's annual dividend and
interest requirements decreased by approximately $2.7 million and $0.8 million,
respectively. The inducement resulted in a 1996 conversion fee charge of
approximately $2.2 million paid in 285,000 shares of Common Stock.

                                       24
<PAGE>   25
         On January 30, 1995, the Company obtained stockholder approval of the
issuance of 11,709,602 shares of Common Stock to TPG and an affiliate, for $50
million (less approximately $5.0 million of direct offering costs and other
costs related to an amendment to the 1994 Notes).

DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS

         This quarterly report includes forward looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended ("Forward Looking
Statements"). All statements other than statements of historical fact included
in this section, are Forward Looking Statements. Although the Company believes
that the expectations reflected in such Forward Looking Statements are
reasonable, it can give no assurance that such expectations will prove to have
been correct. Generally, these statements relate to business plans or
strategies, projected or anticipated benefits or other consequences of such
plans or strategies, number of acquisitions and projected or anticipated
benefits from acquisitions made by or to be made by the Company, or projections
involving anticipated revenues, earnings, levels of capital expenditures or
other aspects of operating results. All phases of the Company operations are
subject to a number of uncertainties, risks and other influences, many of which
are outside the control of the Company and any one of which, or a combination of
which, could materially affect the results of the Company's operations and
whether Forward Looking Statements made by the Company ultimately prove to be
accurate. Such important factors ("Important Factors") that could cause actual
results to differ materially from the Company's expectations are disclosed in
this section and elsewhere in this report. All subsequent written and oral
Forward Looking Statements attributable to the Company or persons acting on its
behalf are expressly qualified in their entirety by the Important Factors
described below that could cause actual results to differ from the Company's
expectations.

         Competition. The solid waste collection and disposal business is highly
competitive and requires substantial amounts of capital. The Company competes
with numerous waste management companies, a number of which have significantly
larger operations and greater resources than the Company. The Company also
competes with those counties and municipalities that maintain their own waste
collection and disposal operations. Forward Looking Statements assume that the
Company will be able to effectively compete with the other waste management
companies.

         Availability of Acquisition Targets. The Company's ongoing acquisition
program is a key element of its expansion strategy. In addition, obtaining
landfill permits has become increasingly difficult, time consuming and
expensive. There can be no assurance, however, that the Company will succeed in
obtaining landfill permits or locating appropriate acquisition candidates that
can be acquired at price levels that the Company considers appropriate and that
reflects historical prices. The Forward Looking Statements assume that a number
of acquisition candidates and landfill properties sufficient to meet the
Company's goals will be available for purchase and that the Company will be able
to complete the acquisition at prices that the Company has experienced in the
past two years.

         Integration. The Company's financial position and results of operations
depend to a large extent on the integration of recently acquired businesses. The
Forward Looking Statements assume that integration of acquired companies,
including the internalization of waste, will require from three to nine months
from the date the acquisition closes. Failure to achieve effective integration
in the anticipated time period or at all could have an adverse effect on the
Company's future results of operations.

         Ongoing Capital Requirements. To the extent that internally generated
cash and cash available under the Company's existing credit facilities are not
sufficient to provide the cash required for future operations, capital
expenditures, acquisitions, debt repayment obligations and/or financial
assurance obligations, the Company will require additional equity and/or debt
financing in order to provide such cash. The Company has incurred significant
debt obligations in the last two years, which entail substantial debt service
costs. The Forward Looking Statements assume that the Company will be able to
raise the capital necessary to finance such requirements at rates that are as
good as or better than those it is currently experiencing. There can be no
assurance, however, that such financing will be available or, if available, will
be available on terms satisfactory to the Company.

                                       25
<PAGE>   26
         Economic Conditions. The Company's business is affected by general
economic conditions. The Forward Looking Statements assume that the Company will
be able to achieve internal volume and price growth which is not impacted by an
economic downturn. (As revenue of the Company continues to grow it is likely
that the rates of internal growth will reflect growth rates which are less than
those experienced in 1996.) There can be no assurance that an economic downturn
will not result in a reduction in the volume of waste being disposed of at the
Company's operations and/or the price that the Company can charge for its
services.

         Weather Conditions. Protracted periods of inclement weather may
adversely affect the Company's operations by interfering with collection and
landfill operations, delaying the development of landfill capacity and/or
reducing the volume of waste generated by the Company's customers. In addition,
particularly harsh weather conditions may result in the temporary suspension of
certain of the Company's operations. The Forward Looking Statements do not
assume that such weather conditions will occur.

         Dependence on Senior Management. The Company is highly dependent upon
its senior management team. In addition, as the Company continues to grow, its
requirements for operations management with waste industry experience will also
increase. The availability of such experienced management is not known. The
Forward Looking Statements assume that experienced management will be available
when needed by the Company at compensation levels that are within industry
norms. The loss of the services of any member of senior management or the
inability to hire experienced operations management could have a material
adverse effect on the Company.

         Influence of Government Regulation. The Company's operations are
subject to and substantially affected by extensive federal, state and local
laws, regulations, orders and permits, which govern environmental protection,
health and safety, zoning and other matters. These regulations may impose
restrictions on operations that could adversely affect the Company's results,
such as limitations on the expansion of disposal facilities, limitations on or
the banning of disposal of out-of-state waste or certain categories of waste or
mandates regarding the disposal of solid waste. Because of heightened public
concern, companies in the waste management business may become subject to
judicial and administrative proceedings involving federal, state or local
agencies. These governmental agencies may seek to impose fines or to revoke or
deny renewal of operating permits or licenses for violations of environmental
laws or regulations or to require remediation of environmental problems at sites
or nearby properties, or resulting from transportation or predecessors'
transportation and collection operations, all of which could have a material
adverse effect on the Company. Liability may also arise from actions brought by
individuals or community groups in connection with the permitting or licensing
of operations, any alleged violations of such permits and licenses or other
matters. The Forward Looking Statements assume that there will be no materially
negative impact on its operations due to government regulation.

         Potential Environmental Liability. The Company may incur liabilities
for the deterioration of the environment as a result of its operations. Any
substantial liability for environmental damage could materially adversely affect
the operating results and financial condition of the Company. Due to the limited
nature of the Company's insurance coverage of environmental liability, if the
Company were to incur liability for environmental damage, its business and
financial condition could be materially adversely affected. The Forward Looking
Statements assume that the Company will not incur any material environmental
liabilities other than those for which a provision has been recorded in the
consolidated financial statements and disclosed in the notes thereto.

INFLATION AND PREVAILING ECONOMIC CONDITIONS

         To date, inflation has not had a significant impact on the Company's
operations. Consistent with industry practice, most of the Company's contracts
provide for a pass through of certain costs, including increases in landfill
tipping fees and, in some cases, fuel costs. The Company therefore believes it
should be able to implement price increases sufficient to offset most cost
increases resulting from inflation. However, competitive factors may require the
Company to absorb cost increases, resulting from inflation. The Company is
unable to determine the future impact of a sustained economic slowdown.

SEASONALITY

         The Company believes that its collection and landfill operations can be
adversely affected by protracted periods of inclement weather which could delay
the development of landfill capacity or transfer of waste and/or reduce the
volume of waste generated.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         In connection with the financing of the Senior Credit Facility, the
Company has entered into interest rate swap agreements (the "Agreements") with
reputable national banks and investment banking institutions to reduce its
exposure to market changes in interest rates. See footnote 1 to Condensed
Consolidated Financial Statements. The Company's use of the Agreements has not
been and is not expected to be material with respect to its financial position
or results of operations.

                                    ARTICLE I

                                  STOCKHOLDERS

         Section 1.1. Annual Meetings. An annual meeting of stockholders shall
be held for the election of directors at such date, time and place, either
within or without the State of Delaware, as may be designated by resolution of
the Board of Directors from time to time; provided, that each successive annual
meeting shall be held on a date within 13 months after the date of the preceding
annual meeting. Any other proper business may be transacted at the annual
meeting.

         Section 1.2. Special Meetings. Special meetings of stockholders for any
purpose or purposes may be called at any time by the Board of Directors, or by a
committee of the Board of Directors which has been duly designated by the Board
of Directors, and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by a stockholder, or any other
person or persons.

         Section 1.3. Notice of Meeting; Waiver of Notice. Whenever stockholders
are required or permitted to take any action at a meeting, a written notice of
the meeting shall be given which shall state the place, date and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called. Unless otherwise provided by law, the written
notice of any meeting shall be given not less than ten nor more than 60 days
before the date of the meeting to each stockholder entitled to vote at such
meeting. If mailed, such notice shall be deemed to be given when deposited in
the mail, postage prepaid, directed to the stockholder at his address as it
appears on the records of the Corporation. Notice need not be given to any
stockholder who submits a written waiver of notice, signed by such stockholder,
whether before or after the time stated therein. Attendance of a person at a
meeting of the stockholders shall constitute a waiver of notice of such meeting,
except when the stockholder attends a meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
stockholders need be specified in any written waiver of notice.

         Section 1.4. Adjournments. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the


                                        1
<PAGE>   2
adjournment is taken. At the adjourned meeting the Corporation may transact any
business which might have been transacted at the original meeting. If the
adjournment is for more than 30 days, or if after the adjournment a new record
date is fixed for the adjourned meeting, a notice of the adjourned meeting shall
be given to each stockholder of record entitled to vote at the meeting.

         Section 1.5. Quorum. At each meeting of stockholders, except as
otherwise provided by law, the Certificate of Incorporation, or these Bylaws,
the holders of a majority of the votes entitled to be cast at the meeting,
present in person or by proxy, shall constitute a quorum. In the absence of a
quorum, the stockholders so present may, by majority vote, adjourn the meeting
from time to time in the manner provided in Section 1.4 of these bylaws until a
quorum shall attend. Shares of its own stock belonging to the Corporation or to
another corporation, if a majority of the shares entitled to vote in the
election of directors of such other corporation is held, directly or indirectly,
by the Corporation, shall neither be entitled to vote nor be counted for
purposes of determining the existence of a quorum; provided, however, that the
foregoing shall not limit the right of any corporation to vote stock, including
but not limited to its own stock, held by it in a fiduciary capacity.

         Section 1.6. Organization. Meetings of stockholders shall be presided
over by the Chairman of the Board, if any, or in his absence by the Vice
Chairman of the Board, if any, or in his absence by the President, or in his
absence by a vice president, or in the absence of the foregoing persons by a
chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the chairman of the meeting may
appoint any person to act as secretary of the meeting.

         Section 1.7. Voting; Proxies. Each stockholder entitled to vote at any
meeting of stockholders shall be entitled to the number of votes designated by
the Certificate of Incorporation, except as otherwise provided by law or these
Bylaws, for each share of stock held by him which has voting power upon the
matter in question. Each stockholder entitled to vote at a meeting of
stockholders may authorize another person or persons to act for him by proxy,
but no such proxy shall be voted or acted upon after three years from its date,
unless the proxy provides for a longer period. A duly executed proxy shall be
irrevocable if it states that it is irrevocable and if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power. A
stockholder may revoke any proxy which is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or another duly executed proxy bearing a later date with the Secretary of
the Corporation. Voting at meetings of stockholders need not be by written
ballot unless the holders of a majority of the outstanding shares of all classes
of stock entitled to vote thereon present in person or by proxy at such meeting
shall so determine; provided, however, that all elections of directors must be
by written ballot. The Corporation shall, in advance of any meeting of
stockholders, appoint one or more inspectors to act at the meeting and make a
written report thereof. At all meetings of stockholders for the election of
directors a plurality of the votes cast shall be sufficient to elect any
nominee. All other elections and questions shall, unless otherwise provided by
law or by the Certificate of Incorporation or these Bylaws, be decided by the
vote of the holders of a majority of the votes entitled to be cast thereon
present in person or


                                        2
<PAGE>   3
by proxy at the meeting, provided that (except as otherwise required by law or
by the certificate of incorporation) the Board of Directors may require a larger
vote upon any election or question.

         Section 1.8.      Record Dates.

                  (a) Meetings. In order that the Corporation may determine the
stockholders entitled to notice of, or to vote at, any meeting of stockholders
or any adjournment thereof, or entitled to receive payment of any dividend or
other distribution or allotment of any rights, or entitled to exercise any
rights in respect of any change, conversion or exchange of stock or for the
purpose of any other lawful action, the Board of Directors may fix, in advance,
a record date, which shall not be more than 60 nor less than ten days before the
date of such meeting, nor more than 60 days prior to any other action. If no
record date is fixed: (1) the record date for determining stockholders entitled
to notice of, or to vote at, a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held; and (2) the record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.

                  (b) Action by Written Consent. In order that the Corporation
may determine the stockholders entitled to consent to corporate action in
writing without a meeting, the Board of Directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted by the Board of Directors, and which date shall not be
more than ten days after the date upon which the resolution fixing the record
date is adopted by the Board of Directors. Any stockholder of record seeking to
have the stockholders authorize or take corporate action by written consent
shall, by written notice to the Secretary, request the Board of Directors to fix
a record date. The Board of Directors shall promptly, but in all events within
ten days after the date on which such a request is received, adopt a resolution
fixing the record date (unless a record date has previously been fixed by the
Board of Directors pursuant to the first sentence of this Section 1.8(b)). If no
record date has been fixed by the Board of Directors pursuant to the first
sentence of this Section 1.8(b) or otherwise within ten days of the date on
which such a request is received, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting, when no
prior action by the Board of Directors is required by applicable law, shall be
the first date on which a signed written consent setting forth the action taken
or proposed to be taken is delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business, or to any
officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by applicable law, the record date for determining
stockholders entitled to consent to corporate action in writing without

a meeting shall be at the close of business on the date on which the Board of
Directors adopts the resolution taking such prior action.

                  (c) Inspectors of Written Consent. In the event of the
delivery, in the manner provided by Section 1.8(b), to the Corporation of the
requisite written consent or consents to take corporate action and/or any
related revocation or revocations, the Corporation may engage independent
inspectors of elections for the purpose of performing promptly a ministerial
review of the validity of the consents and revocations. For the purpose of
permitting the inspectors to perform such review, no action by written consent
without a meeting shall be effective until such date as the independent
inspectors certify to the Corporation that the consents delivered to the
Corporation in accordance with Section 1.8(b) represent at least the minimum
number of votes that would be necessary to take the corporate action. Nothing
contained in this Section 1.8(c) shall in any way be construed to suggest or
imply that the Board of Directors or any stockholder shall not be entitled to
contest the validity of any consent or revocation thereof, whether before or
after such certification by the independent inspectors, or to take any other
action (including, without limitation, the commencement, prosecution, or defense
of any litigation with respect thereto, and the seeking of injunctive relief in
such litigation).

                  (d) Effectiveness of Written Consent. Every written consent
shall bear the date of signature of each stockholder who signs the consent and
no written consent shall be effective to take the corporate action referred to
therein unless, within sixty days of the earliest dated written consent received
in accordance with Section 1.8(b), a written consent or consents signed by a
sufficient number of holders to take such action are delivered to the
Corporation in the manner prescribed in Section 1.8(b).

         Section 1.9. List of Stockholders Entitled to Vote. The Secretary shall
prepare and make, at least ten days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any stockholder who is present. The stock ledger
shall be the only evidence as to who are the stockholders or the books of the
Corporation, or to vote in person or by proxy at any meeting of stockholders.

         Section 1.10. Director Nominees. Only persons who are nominated in
accordance with the procedures set forth in this paragraph shall be eligible for
election as directors of the Corporation. Nominations of persons for election to

stockholders (a) by or at the direction of the Board of Directors or (b) by any
stockholder of the Corporation entitled to vote for the election of directors at
such meeting who complies with 


                                       4
<PAGE>   5
the procedures set forth in this paragraph. All nominations by stockholders
shall be made pursuant to timely notice in proper written form to the Secretary
of the Corporation. To be timely, a stockholder's notice shall be delivered to,
or mailed and received at, the principal executive offices of the Corporation
not less than 75 days nor more than 120 days prior to the anniversary date of
the immediately preceding annual meeting of stockholders (the "Anniversary
Date"); provided, however, that in the event the annual meeting is scheduled to
be held on a date more than 30 days before the Anniversary Date or more than 60
days after the Anniversary Date, notice by the stockholder to be timely must be
delivered not later than the close of business on the later of (a) the 75th day
prior to the scheduled date of such annual meeting or (b) the 15th day following
the day on which public announcement of the date of such annual meeting is first
made by the Corporation. In no event shall the public announcement of an
adjournment of an annual meeting commence a new time period for the giving of a
stockholder's notice under these Bylaws. Notwithstanding anything to the
contrary in this paragraph, in the event that the number of directors to be
elected to the Board of Directors or the Corporation is increased and there is
no public announcement by the Corporation naming all of the nominees for
director or specifying the size of the increased Board of Directors at least 75
days prior to the Anniversary date, a stockholder's notice required by this
paragraph shall also be considered timely, but only with respect to nominees for
any new position created by such increase, if such notice shall be delivered to,
or mailed to and received by the Corporation at its principal executive office
not later than the close of business on the 15th day following the day on which
such public announcement is first made by the Corporation. To be in proper
written form, such stockholder's notice to the Secretary shall set forth in
writing (a) as to each person whom such stockholder proposes to nominate for
election or re-election as a director, (i) the name, age, business address and
residence address of such person, (ii) the principle occupation or employment of
such person, (iii) the class and number of shares of the Corporation which are
beneficially owned by such person, and (iv) all information relating to such
person that is required to be disclosed in solicitations of proxies for election
of directors, or is otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended, including, without
limitation, such person's written consent to being named in the proxy statement
as a nominee and to serving as a director if elected; and (b) as to such
stockholder giving notice, (i) his or her name and address, as they appear on
the Corporation's books, (ii) the class and number of shares of stock of the
Corporation which are beneficially owned by such stockholder, and (iii) a
description of all arrangements or understandings between such stockholder and
each nominee and any other person or persons pursuant to which the nomination or
nominations are to be made by such stockholder. At the request of the Board of
Directors, any person nominated by the Board of Directors for election as a
director shall furnish to the Secretary of the Corporation that information
required to be set forth in a stockholder's notice of nomination which pertains
to the nominee. No person shall be eligible for election as a director unless
nominated in accordance with the procedures set forth in the Bylaws of the
Corporation. The chairman of the meeting shall, if the facts warrant, determine
and declare to the meeting that a nomination was not made in accordance with the
procedures prescribed by the Bylaws of the Corporation, and if he shall so
determine, he shall so declare to the meeting and the defective nomination shall
be disregarded.

Board of Directors or (b) by any stockholder who complies with the procedures
set forth in this paragraph. For business properly to be brought before an

thereof in proper written form to the Secretary of the Corporation. To be
timely, a stockholder's notice must be delivered to, or mailed and received at,
the principal executive offices of the Corporation not less than 75 days nor
more than 120 days prior to the Anniversary Date; provided, however, that in the
event the annual meeting is scheduled to be held on a date more than 30 days
before the Anniversary Date or more than 60 days after the Anniversary Date,
timely notice by the stockholder must be delivered not later than the close of
business on the later of (a) the 75th day prior to the scheduled date of such
annual meeting or (b) the 15th day following the day on which the public
announcement of the date of such annual meeting is first made by the
Corporation. In no event shall the public announcement of an adjournment of an
annual meeting commence a new time period for the giving of a stockholder's
notice under these Bylaws. To be in proper written form, such stockholder's
notice to the Secretary shall set forth in writing as to each matter such
stockholder proposes to bring before the annual meeting (a) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (b) his or her name and
address, as they appear on the Corporation's books, (c) the class and number of
shares of stock of the Corporation which are beneficially owned by such

stockholder proposing such business to support such proposal, and the class and
number of shares of the Corporation's capital stock beneficially owned by such
other stockholders, and (e) any material interest on such stockholder in such
business. Notwithstanding anything in these Bylaws to the contrary, no business
shall be conducted at any annual meeting except in accordance with the
procedures set forth in this paragraph. The chairman of an annual meeting shall,
if the facts warrant, determine and declare to the meeting that business was not
properly brought before the meeting in accordance with the provisions of this
paragraph, and, if he should so determine, he shall so declare to the meeting
and any such business not properly brought before the meeting shall not be
transacted.

directors shall consist of no more than twelve (12) directors; provided,
however, that if Mr. O'Leary ceases to serve as a director, the board of

Shareholder Designee Period.

         Section 2.3. Election; Resignation; Removal; Vacancies. The Board of

cause, at any time by the affirmative vote of a majority in interest of the
holders of record of stock entitled to vote at an election of directors, at an
annual meeting or at a special meeting of the stockholders called for that
purpose. Any vacancy occurring in the Board of Directors, for whatever reason,
may be filled by a majority of the remaining members of the Board of Directors,
although such majority is less than a quorum, or by a plurality of the votes
cast at a meeting of stockholders, and each director so elected shall hold
office until the expiration of the term of the director whom he has replaced.

         At all times during the Shareholder Designee Period, subject to Section
3.1(d) of the Shareholders Agreement, the Company shall support the nomination

less than 75% of the Shares, (C) two Shareholder Designees, so long as
Shareholders beneficially own 25% or more but less than 50% of the Shares and
(D) one Shareholder Designee, so long as Shareholders beneficially own 20% or
more but less than 25% of the Shares (each a "Beneficial Ownership Threshold"),
provided that if at any time as a result of the Company's issuance of Voting
Securities (as defined in the Shareholders Agreement) Shareholders beneficially
own 9% or less of the Actual Voting Power (as defined in the Shareholders
Agreement) (the "Actual Voting Power Threshold"), Shareholders shall be entitled
to no more than one Shareholder Designee, and (iii) such other persons, each of
whom is (A) recommended by the Nominating Committee and (B) not an employee or
officer of or outside counsel to the Company or a partner, employee, director,
officer, affiliate or associate (as defined in Rule 12b-2 under the Exchange
Act) of any Shareholder or any affiliate of a Shareholder or as to which the
Shareholders or their affiliates own at lest ten percent of the voting equity
securities ("Unaffiliated Directors"). If any vacancy (whether by death,
retirement, disqualification, removal from office or other cause, or by increase
in number of

(i) may appoint a member of management to fill a vacancy caused by a Management
Director ceasing to serve as a director, (ii) shall appoint, subject to Section
3.1(d) of the Shareholders Agreement, a person designated by the Shareholders to
fill a vacancy created by a Shareholder Designee ceasing to serve as a director
(except as a result of the reduction of the number of Shareholder Designees
entitled to be included on the Board of Directors by reason of a decrease in
Shareholders beneficial ownership of Common Stock below any Beneficial Ownership
Threshold or Voting Securities below the Actual Voting Power Threshold), and
(iii) may appoint a person who qualifies as an Unaffiliated Director and is
recommended by the Nominating Committee pursuant to the procedures set forth in
the following paragraph to fill a vacancy created by an Unaffiliated Director
ceasing to serve as a director (provided that in the case of a vacancy relating
to an Unaffiliated Director, if a majority of the Nominating Committee is unable
to recommend a replacement, then the Board seat with respect to this vacancy
shall remain vacant), and each such person shall be a Management Designee,
Shareholder Designee or Unaffiliated Director, as the case may be, for purposes
of this Agreement. Upon any decrease in Shareholders' beneficial ownership of
Common Stock below any Beneficial Ownership Threshold or Voting Securities below
the actual Voting Power Threshold, Shareholders shall cause a number of
Shareholder Designees to offer to immediately resign from the Board of Directors
such that the number of Shareholder Designees serving on the Board of Directors
immediately thereafter will be equal to the number of Shareholder Designees
which Shareholders would then be entitled to designate under Section 3.1(b) of

committee thereof, may be taken without a meeting if all members of the Board of
Directors or of such committee, as the case may be, consent thereto in writing,
and the writing or writings are filed with the minutes of proceedings of the
Board of Directors or of such committee.

         Section 2.10. Compensation of Directors. Directors may receive such
sums as compensation for their services and expenses as may be directed by
resolution of the Board of Directors; provided that nothing herein contained
shall be construed to preclude any director from serving the Corporation in any
other capacity, and receiving compensation therefor. Members of special or
standing committees may be allowed like compensation for their service and
expenses.

further, that unless the resolution expressly so provides, no such committee
shall have the power or authority to declare a dividend or to authorize the
issuance of stock.

         Section 3.2. Committee Rules. Unless the Board of Directors otherwise
provides, each committee designated by the Board of Directors may make, alter

each committee shall conduct its business in the same manner as the Board of
Directors conducts its business pursuant to Article II of these Bylaws.

shall be either Management Directors or Unaffiliated Directors. If the
Nominating Committee is unable to recommend one or more persons to serve as
Unaffiliated Directors (except with respect to any vacancy created by an
Unaffiliated Director ceasing to serve as such), then the Board of Directors
shall nominate and recommend for election by stockholders an Unaffiliated
Director then serving on the Board of Directors. Notwithstanding the foregoing,
if the Shareholders beneficially own less than 50% of the Shares, the Nominating
Committee shall be comprised of individuals only one of whom is a Shareholder
Designee.

                                 INDEMNIFICATION

         Section 6.1. Indemnification in Non-Derivative Proceedings. The
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation) by reason of the fact that he
is or was a director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         Section 6.2. Indemnification in Derivative Proceedings. The Corporation
shall indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action or suit by or in the right
of the Corporation to procure a judgment in its favor by reason of the fact that
he is or was a director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another Corporation, partnership, joint venture, trust or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Corporation; provided, however, that
no indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless, and only to the extent that, the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the court
shall deem proper.

         Section 6.3. Indemnification when Director, Officer or Employee
Successful in Defense of Action. To the extent that a director, officer,
employee or agent of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in Sections
6.1 and 6.2 of this Article, or in defense of any claim, issue or matter
therein, the Corporation shall indemnify such director, officer, employee or
agent against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

         Section 6.4. Determination of Right to Indemnification. Any
indemnification under Sections 6.1 and 6.2 of this Article (unless ordered by a
court) shall be made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in Sections 6.1 and 6.2 of this Article. Such determination
shall be made (1) by the Board of Directors, by a majority vote of a quorum
consisting of directors who were not parties to such action, suit or proceeding,
or (2) if such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (3) by the stockholders.

         Section 6.5. Advancement of Expenses. Expenses incurred by an officer
or director in defending a civil or criminal action, suit or proceeding shall be
paid by the Corporation in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such expenses incurred by other employees and agents shall be so paid upon such
terms and conditions, if any, as the Board of Directors deems appropriate.

         Section 6.6. Rights Hereunder Not Exclusive. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall
not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in an official capacity and as to action in another capacity while
holding such office.

         Section 6.7. Insurance. The Corporation shall have the power to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under the General
Corporation Law of the State of Delaware or this Article.

         Section 6.8. Definition of Corporation. For purposes of this Article,
references to "the Corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

         Section 6.9. Certain Definitions. For purposes of this Article,
references to "other enterprises" shall include employee benefit plans;
references to "fines" shall include any excise taxes assessed on a person with
respect to any employee benefit plan; and references to "serving at the request
of the Corporation" shall include any service as a director, officer, employee
or agent of the Corporation which imposes duties on, or involves services by,
such director, officer, employee or agent with respect to an employee benefit
plan, its participants or beneficiaries; and a person who acted in good faith
and in a manner he reasonably believed to be in the interest of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this section.

         Section 6.10. Continuation of Rights. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Article shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and administrators
of such a person.

                                   ARTICLE VII

                                  MISCELLANEOUS

         Section 7.1. Fiscal Year. The fiscal year of the Corporation shall
begin on the first day of January in each year and shall end on the last day of
December next following.

         Section 7.2. Seal. The corporate seal shall have the name of the
Corporation inscribed thereon and shall be in such form as may be approved from
time to time by the Board of Directors.

         Section 7.3. Interested Directors; Quorum. No contract or transaction
between the Corporation and one or more of its directors or officers, or between
the Corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes the contract or transaction, or solely because his or their votes are
counted for such purpose, if: (1) the material facts as to his relationship or
interest and as to the contract or transaction are disclosed or are known to the
Board of Directors or the committee, and the Board of Directors or committee in
good faith authorizes the contract or transaction by the affirmative votes of a
majority of the disinterested directors, even though the disinterested directors
be less than a quorum; or (2) the material facts as to his relationship or
interest and as to the contract or transaction are disclosed or are known to the
stockholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the stockholders; or (3) the
contract or transaction is fair as to the Corporation as of the time it is


                                       15
<PAGE>   16
authorized, approved or ratified, by the Board of Directors, a committee
thereof, or the stockholders. Common or interested directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or a
committee which authorizes the contract or transaction.

         Section 7.4. Form of Records. Any records maintained by the Corporation
in the regular course of its business, including its stock ledger, books of
account, and minutes books, may be kept on, or be in the form of, punch cards,
magnetic tape, photographs, microphotographs, or any other information storage
device, provided that the records so kept can be converted into clearly legible
form within a reasonable time. The Corporation shall so convert any records so
kept upon the request of any person entitled to inspect the same.

         Section 7.5. Amendment of Bylaws. These bylaws may be altered or
repealed, and new bylaws made, by the Board of Directors. Notwithstanding
anything to the contrary that may be contained herein, Section 2.2, the last
sentence of Section 2.11 and the second sentence of Section 7.5 may only be
amended with the affirmative vote of seven members of the Corporation's Board of
Directors.

with the covenants contained in Article VI, all accounting terms herein shall be
interpreted and all accounting determinations hereunder shall be made in
accordance with GAAP as in effect on the date of this Agreement and applied on a
basis consistent with the application used in the financial statements referred
to in Section 3.05(a).


                                   ARTICLE II

                                   The Credits

         SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, (a) to make Term Loans to the Borrower on the
Closing Date in an aggregate principal amount not to exceed its Term Loan
Commitment and (b) to make Revolving Loans to the Borrower, at any time and from
time to time on or after the date hereof, and until the earlier of the Maturity
Date and the termination of the Revolving Credit Commitment of such Lender in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in (i) such Lender's Revolving Credit Exposure
exceeding (ii) such Lender's Revolving Credit Commitment. Within the limits set
forth in clause (b) of the preceding sentence and subject to the terms,
conditions and limitations set forth herein, the Borrower may borrow, pay or
prepay and reborrow Revolving Loans. Amounts paid or prepaid in respect of Term
Loans may not be reborrowed.

         SECTION 2.02. Loans. (a) Each Loan (other than Swingline Loans) shall
be made as part of a Borrowing consisting of Loans made by the Lenders ratably
in accordance with their respective Revolving Credit Commitments or Term Loan
Commitments, as applicable; provided, however, that the failure of any Lender to
make any Loan shall not in itself relieve any other Lender of its obligation to
lend hereunder (it being understood, however, that no Lender shall be
responsible for the failure of any other Lender to make any Loan required to be
made by such other Lender). Except for Loans deemed made pursuant to Section
2.02(f), the Loans comprising any Borrowing shall be in an aggregate principal
amount that is (i) an integral multiple of $1,000,000 and not less than
$5,000,000 or (ii) equal to the remaining available balance of the applicable
Commitments.

         (b) Subject to Sections 2.08 and 2.15, each Borrowing shall be
comprised entirely of Base Rate Loans or Eurodollar Loans as the Borrower may
request pursuant to Section 2.03. Each Lender may at its option make any
Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not
affect the obligation of the Borrower to repay such Loan in accordance with the
terms of this Agreement. Borrowings of more than one Type may be outstanding at
the same time; provided, however, that the Borrower shall not be entitled to
request any Borrowing that, if made, would result in more than 20 Eurodollar
Borrowings outstanding hereunder at any time. For purposes of the foregoing,
Borrowings having different Interest Periods, regardless of whether they
commence on the same date, shall be considered separate Borrowings.

         (c) Except with respect to Loans made pursuant to Section 2.02(f), each
Lender shall make each Loan to be made by it hereunder on the proposed date
thereof by wire transfer of immediately
<PAGE>   30
                                                                              25

available funds to such account in New York City as the Administrative Agent may
designate not later than 12:00 (noon), New York City time, and the
Administrative Agent shall by 1:00 p.m., New York City time, credit the amounts
so received to an account in the name of the Borrower designated by the Borrower
in the applicable Borrowing Request or, if a Borrowing shall not occur on such
date because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders.

         (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent at (i) in the case of the Borrower, the
interest rate applicable at the time to the Loans comprising such Borrowing and
(ii) in the case of such Lender, for the first such day, the Federal Funds
Effective Rate, and for each day thereafter, the Base Rate. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement, and the Borrower shall be relieved of its obligation pursuant to the
preceding sentence to repay such amount or, if such amount has theretofore been
repaid by the Borrower to the Administrative Agent, the Administrative Agent
shall make such corresponding amount available to the Borrower.

         (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Revolving Credit Borrowing or Term
Borrowing if the Interest Period requested with respect thereto would end after
the Maturity Date.

         (f) If the Issuing Bank shall not have received from the Borrower or
Allied, as the case may be, the payment required to be made by Section 2.23(e)
within the time specified in such Section, the Issuing Bank will promptly notify
the Administrative Agent of the L/C Disbursement and the Administrative Agent
will promptly notify each Revolving Credit Lender of such L/C Disbursement and
its Pro Rata Percentage thereof. Each Revolving Credit Lender shall pay by wire
transfer of immediately available funds to the Administrative Agent not later
than 2:00 p.m., New York City time, on such date (or, if such Revolving Credit
Lender shall have received such notice later than 12:00 (noon), New York City
time, on any day, not later than 12:00 (noon), New York City time, on the
immediately following Business Day), an amount equal to such Lender's Pro Rata
Percentage of such L/C Disbursement (it being understood that such amount shall
be deemed to constitute a Base Rate Revolving Loan of such Lender and such
payment shall be deemed to have reduced the L/C Exposure), and the
Administrative Agent will promptly pay to the Issuing Bank amounts so received
by it from the Revolving Credit Lenders. The Administrative Agent will promptly
pay to the Issuing Bank any amounts received by it from the Borrower pursuant to
Section 2.23(e) prior to the time that any Revolving Credit Lender makes any
payment pursuant to this paragraph (f); any such amounts received by the
Administrative Agent thereafter will be promptly remitted by the Administrative
Agent to the Revolving Credit Lenders that shall have made such payments and to
the Issuing Bank, as their interests may appear. If any Revolving Credit Lender
shall not have made its Pro Rata Percentage of
<PAGE>   31
                                                                              26

such L/C Disbursement available to the Administrative Agent as provided above,
such Lender and the Borrower or Allied, as the case may be, severally agree to
pay interest on such amount, for each day from and including the date such
amount is required to be paid in accordance with this paragraph to but excluding
the date such amount is paid, to the Administrative Agent for the account of the
Issuing Bank at (i) in the case of the Borrower or Allied, as the case may be, a
rate per annum equal to the interest rate applicable to Revolving Loans pursuant
to Section 2.06(a), and (ii) in the case of such Lender, for the first such day,
the Federal Funds Effective Rate, and for each day thereafter, the Base Rate.

         SECTION 2.03. Borrowing Procedure. In order to request a Borrowing
(other than a Swingline Loan or a deemed Borrowing pursuant to Section 2.02(f),
as to which this Section 2.03 shall not apply), the Borrower shall hand deliver
or telecopy to the Administrative Agent a duly completed Borrowing Request (a)
in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before a proposed Borrowing, and (b) in the case of a
Base Rate Borrowing, not later than 1:00 p.m., New York City time, one Business
Day before a proposed Borrowing. Each Borrowing Request shall be irrevocable,
shall be signed by or on behalf of the Borrower and shall specify the following
information: (i) whether the Borrowing then being requested is to be a Term
Borrowing or a Revolving Credit Borrowing, and whether such Borrowing is to be a
Eurodollar Borrowing or a Base Rate Borrowing, provided that any Borrowing on
the Closing Date shall be a Base Rate Borrowing; (ii) the date of such Borrowing
(which shall be a Business Day), (iii) the number and location of the account to
which funds are to be disbursed (which shall be an account that complies with
the requirements of Section 2.02(c)); (iv) the amount of such Borrowing; (v) if
such Borrowing is to be a Eurodollar Borrowing, the Interest Period with respect
thereto; and (vi) if applicable, whether the Borrowing then being requested is a
Bank Facility Loan or an Additional Facility Loan (it being understood that no
Borrowing shall be comprised of any Additional Facility Loans until the
Aggregate Revolving Credit Exposures exceed the Bank Facility Amount); provided,
however, that, (x) notwithstanding any contrary specification in any Borrowing
Request, each requested Borrowing shall comply with the requirements set forth
in Section 2.02 and (y) upon the request of the Administrative Agent, during the
period from and including the Closing Date to but excluding a date not more than
60 days after the Closing Date, the Borrower shall not be entitled to elect to
make Eurodollar Borrowings. If no election as to the Type of Borrowing is
specified in any such notice, then the requested Borrowing shall be a Base Rate
Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is
specified in any such notice, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration. The Administrative Agent shall
promptly advise the applicable Lenders of any notice given pursuant to this
Section 2.03 (and the contents thereof), and of each Lender's portion of the
requested Borrowing.

         SECTION 2.04. Evidence of Debt; Repayment of Loans. (a) The Borrower
hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender (i) the then unpaid principal amount of each Swingline
Loan, on the last day of the Interest Period applicable to such Loan or, if
earlier, on the Maturity Date, (ii) the principal amount of each Term Loan of
such Lender as provided in Section 2.11 and (iii) the then unpaid principal
amount of each Revolving Loan on the Maturity Date.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.
<PAGE>   32
                                                                              27

          (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower or any Guarantor and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) above shall be prima facie evidence of the existence and amounts of
the obligations therein recorded; provided, however, that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligations of the Borrower to repay
the Loans in accordance with their terms.

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall request and receive a promissory note payable to such Lender
and its registered assigns, the interests represented by such note shall at all
times (including after any assignment of all or part of such interests pursuant
to Section 9.04) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

         SECTION 2.05. Fees. (a) The Borrower agrees to pay to each Lender,
through the Administrative Agent, on the Closing Date and on the last Business
Day of March, June, September and December in each year, commencing the last
Business Day of June 1997, and on each date on which any Commitment of such
Lender shall expire or be terminated as provided herein, a commitment fee (a
"Commitment Fee") equal to the Applicable Percentage per annum in effect from
time to time on the average daily unused amount of the Commitments of such
Lender (other than the Swingline Commitment) during the preceding quarter (or
other period commencing with the date of acceptance by the Borrower of the
Commitment of such Lender or ending with the Maturity Date or the date on which
the Commitments of such Lender shall expire or be terminated). All Commitment
Fees shall be computed on the basis of the actual number of days elapsed in a
year of 360 days. The Commitment Fee due to each Lender shall commence to accrue
on the Closing Date and shall cease to accrue on the date on which the
Commitment of such Lender shall expire or be terminated as provided herein. For
purposes of calculating Commitment Fees only, no portion of the Revolving Credit
Commitments shall be deemed utilized under Section 2.17 as a result of
outstanding Swingline Loans.

         (b) The Borrower agrees to pay to the Administrative Agent, for its own
account, the administrative fees set forth in the Fee Letter at the times and in
the amounts specified therein (the "Administrative Agent Fees").

         (c) The Borrower agrees to pay (i) to each Revolving Credit Lender,
through the Administrative Agent, on the last Business Day of March, June,
September and December of each year, commencing the last Business Day of June
1997, and on the date on which the Revolving Credit Commitment of such Lender
shall be terminated as provided herein, a fee (an "L/C Participation Fee")
calculated on such Lender's Pro Rata Percentage of the average daily aggregate
L/C Exposure (excluding the portion thereof attributable to unreimbursed L/C
Disbursements) during the quarter ending on such date (or shorter period
commencing with the date hereof or ending with the Maturity Date or the date on
which all Letters of Credit have been canceled or have expired and the Revolving
Credit Commitments of all Lenders shall have been terminated) at a rate equal to
the Applicable Percentage from time to time used to determine the interest rate
on Revolving Credit Borrowings
<PAGE>   33
                                                                              28

comprised of Eurodollar Loans pursuant to Section 2.06, and (ii) to the Issuing
Bank with respect to each Letter of Credit (x) a fronting fee equal to 1/4 of 1%
per annum of the outstanding face amount of such Letter of Credit, payable
quarterly in arrears and (y) the standard issuance and drawing fees specified
from time to time by the Issuing Bank (the "Issuing Bank Fees"). All L/C
Participation Fees and Issuing Bank Fees shall be computed on the basis of the
actual number of days elapsed in a year of 360 days.

           All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, except that the Issuing Bank Fees shall be paid directly to
the Issuing Bank. Once paid, none of the Fees shall be refundable under any
circumstances.

         SECTION 2.06. Interest on Loans. (a) Subject to the provisions of
Section 2.07, the Loans comprising each Base Rate Borrowing, including each
Swingline Loan, shall bear interest (computed on the basis of the actual number
of days elapsed over a year of 365 or 366 days, as the case may be, when the
Base Rate is determined by reference to the Prime Rate and over a year of 360
days at all other times) at a rate per annum equal to the Base Rate plus the
Applicable Percentage in effect from time to time.

         (b) Subject to the provisions of Section 2.07, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing
plus the Applicable Percentage in effect from time to time.

         (c) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Base Rate or Adjusted LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

         SECTION 2.07. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, or under any other Loan Document,
the Borrower shall on demand from time to time pay interest, to the extent
permitted by law, on such defaulted amount to but excluding the date of actual
payment (after as well as before judgment) (a) in the case of overdue principal,
at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus
2.00% per annum and (b) in all other cases, a rate per annum (computed on the
basis of the actual number of days elapsed over a year of 365 or 366 days, as
the case may be, when determined by reference to the Prime Rate and over a year
of 360 days at all other times) equal to the sum of the Base Rate plus the
Applicable Percentage applicable to Base Rate Loans plus 2.00%.

         SECTION 2.08. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined that dollar deposits in the principal amounts of the Loans comprising
such Borrowing are not generally available in the London interbank market, or
that the rates at which such dollar deposits are being offered will not
adequately and fairly reflect the cost to any Lender of making or maintaining
its Eurodollar Loan during such Interest Period, or that reasonable means do not
exist for ascertaining the Adjusted LIBO Rate, the Administrative Agent shall,
as soon as practicable thereafter, give written or telecopy notice of such
determination to the
<PAGE>   34
                                                                              29

Borrower and the Lenders. In the event of any such determination, until the
Administrative Agent shall have advised the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, any request by the
Borrower for a Eurodollar Borrowing pursuant to Section 2.03 or 2.10 shall be
deemed to be a request for a Base Rate Borrowing. Each determination by the
Administrative Agent hereunder shall be conclusive absent manifest error.

         SECTION 2.09. Termination and Reduction of Commitments. (a) Each
Lender's Term Loan Commitment shall terminate (i) at the time such Lender makes
the Term Loans to be made by it on the Closing Date in accordance with Section
2.01 or (ii) in the event any such Lender reasonably determines that the
conditions precedent set forth in Section 4.02 have not be satisfied on or prior
to the Closing Date, at 5:00 p.m., New York City time, on the Closing Date. The
Revolving Credit Commitments, the Swingline Commitment and the L/C Commitment
shall automatically terminate on the Maturity Date. Notwithstanding the
foregoing, all the Commitments shall automatically terminate at 5:00 p.m., New
York City time, on June 16, 1997, if the initial Credit Event shall not have
occurred by such time.

         (b) Upon at least five Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Term Loan Commitments or the Revolving Credit Commitments; provided,
however, that (i) each partial reduction of the Term Loan Commitments or the
Revolving Credit Commitments shall be in an integral multiple of $1,000,000 and
in a minimum amount of $5,000,000 and (ii) the Total Revolving Credit Commitment
shall not be reduced to an amount that is less than the Aggregate Revolving
Credit Exposure at the time.

         (c) Each reduction in the Term Loan Commitments or the Revolving Credit
Commitments hereunder shall be made ratably among the Lenders in accordance with
their respective applicable Commitments. The Borrower shall pay to the
Administrative Agent for the account of the applicable Lenders, on the date of
each termination or reduction, the Commitment Fees on the amount of the
Commitments so terminated or reduced accrued to but excluding the date of such
termination or reduction.

         SECTION 2.10. Conversion and Continuation of Borrowings. The Borrower
shall have the right at any time upon prior irrevocable notice to the
Administrative Agent (a) not later than 12:00 (noon), New York City time, one
Business Day prior to conversion, to convert any Eurodollar Borrowing into a
Base Rate Borrowing, (b) not later than 11:00 a.m., New York City time, three
Business Days prior to conversion or continuation, to convert any Base Rate
Borrowing into a Eurodollar Borrowing or to continue any Eurodollar Borrowing as
a Eurodollar Borrowing for an additional Interest Period, and (c) not later than
11:00 a.m., New York City time, three Business Days prior to conversion, to
convert the Interest Period with respect to any Eurodollar Borrowing to another
permissible Interest Period, subject in each case to the following:

                  (i) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Loans comprising the converted or continued Borrowing;

                  (ii) if less than all the outstanding principal amount of any
         Borrowing shall be converted or continued, then each resulting
         Borrowing shall satisfy the limitations specified
<PAGE>   35
                                                                              30

         in Sections 2.02(a) and 2.02(b) regarding the principal amount and
         maximum number of Borrowings of the relevant Type;

                  (iii) each conversion shall be effected by each Lender and the
         Administrative Agent by recording for the account of such Lender the
         new Loan of such Lender resulting from such conversion and reducing the
         Loan (or portion thereof) of such Lender being converted by an
         equivalent principal amount; accrued interest on any Eurodollar Loan
         (or portion thereof) being converted shall be paid by the Borrower at
         the time of conversion;

                  (iv) if any Eurodollar Borrowing is converted at a time other
         than the end of the Interest Period applicable thereto, the Borrower
         shall pay, upon demand, any amounts due to the Lenders pursuant to
         Section 2.16;

                  (v) any portion of a Borrowing maturing or required to be
         repaid in less than one month may not be converted into or continued as
         a Eurodollar Borrowing;

                  (vi) any portion of a Eurodollar Borrowing that cannot be
         converted into or continued as a Eurodollar Borrowing by reason of the
         immediately preceding clause shall be automatically converted at the
         end of the Interest Period in effect for such Borrowing into a Base
         Rate Borrowing;

                  (vii) no Interest Period may be selected for any Eurodollar
         Term Borrowing that would end later than a Term Loan Repayment Date
         occurring on or after the first day of such Interest Period if, after
         giving effect to such selection, the aggregate outstanding amount of
         (A) the Eurodollar Term Borrowings with Interest Periods ending on or
         prior to such Term Loan Repayment Date and (B) the Base Rate Term
         Borrowings, would not be at least equal to the principal amount of Term
         Borrowings to be paid on such Term Loan Repayment Date;

                  (viii) after the occurrence and during the continuance of a
         Default or Event of Default, no outstanding Loan may be converted into,
         or continued as, a Eurodollar Loan; and

                  (ix) upon the request of the Administrative Agent, during the
         period from and including the Closing Date to but excluding a date not
         more than 60 days after the Closing Date, no Borrowing may be converted
         into a Eurodollar Borrowing.

         Each notice pursuant to this Section 2.10 shall be irrevocable and
shall refer to this Agreement and specify (i) the identity and amount of the
Borrowing that the Borrower requests be converted or continued, (ii) whether
such Borrowing is to be converted to or continued as a Eurodollar Borrowing or a
Base Rate Borrowing, (iii) if such notice requests a conversion, the date of
such conversion (which shall be a Business Day) and (iv) if such Borrowing is to
be converted to or continued as a Eurodollar Borrowing, the Interest Period with
respect thereto. If no Interest Period is specified in any such notice with
respect to any conversion to or continuation as a Eurodollar Borrowing, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. The Administrative Agent shall advise the Lenders of any notice given
pursuant to this Section 2.10 and of each Lender's portion of any converted or
continued Borrowing. If the Borrower shall not have given notice in accordance
with this Section 2.10 to continue any Borrowing into a subsequent Interest
Period (and shall not otherwise have given notice in accordance with this
Section 2.10 to convert such Borrowing),
<PAGE>   36
                                                                              31

such Borrowing shall, at the end of the Interest Period applicable thereto
(unless repaid pursuant to the terms hereof), automatically be continued into a
new Interest Period as a Base Rate Borrowing.

         SECTION 2.11. Repayment of Term Borrowings. (a) (i) The Borrower shall
pay to the Administrative Agent, for the account of the Lenders, on the dates
set forth below, or if any such date is not a Business Day, on the next
succeeding Business Day (each such date being a "Term Loan Repayment Date"), a
principal amount of the Term Loans (such amount, as adjusted from time to time
pursuant to Sections 2.11(b), 2.12 and 2.13, being called the "Term Loan
Repayment Amount") equal to the amount set forth below for such date, together
in each case with accrued and unpaid interest on the principal amount to be paid
to but excluding the date of such payment:

         (b) In the event and on each occasion that any Term Loan Commitments
shall be reduced or shall expire or terminate other than as a result of the
making of a Term Loan, the installments payable
<PAGE>   37
                                                                              32

on each Term Loan Repayment Date shall be reduced pro rata by an aggregate
amount equal to the amount of such reduction, expiration or termination.

          (c) To the extent not previously paid, all Term Loans shall be due and
payable on the Maturity Date, together with accrued and unpaid interest on the
principal amount to be paid to but excluding the date of payment.

          (d) All repayments pursuant to this Section 2.11 shall be subject to
Section 2.16, but shall otherwise be without premium or penalty.

         SECTION 2.12. Optional Prepayments. (a) The Borrower shall have the
right at any time and from time to time to prepay any Borrowing, in whole or in
part, upon at least three Business Days' prior written or telecopy notice (or
telephone notice promptly confirmed by written or telecopy notice) to the
Administrative Agent before 11:00 a.m., New York City time; provided, however,
that each partial prepayment and reduction shall be in an amount that is an
integral multiple of $1,000,000 and not less than $5,000,000.

         (b) Optional prepayments of Term Loans shall be applied pro rata
against the remaining scheduled installments of principal due in respect of the
Term Loans under Section 2.11(a).

         (c) Each notice of prepayment shall specify the prepayment date,
whether the Borrowing being prepaid is a Term Borrowing or a Revolving Credit
Borrowing and the principal amount of each Borrowing (or portion thereof) to be
prepaid, shall be irrevocable and shall commit the Borrower to prepay such
Borrowing by the amount stated therein on the date stated therein. All
prepayments under this Section 2.12 shall be subject to Section 2.16, but
otherwise without premium or penalty. All prepayments of Eurodollar Loans under
this Section 2.12 shall be accompanied by accrued interest on the principal
amount being prepaid to the date of payment.

         SECTION 2.13. Mandatory Prepayments. (a) In the event of any
termination of all the Revolving Credit Commitments, the Borrower shall repay or
prepay all its outstanding Revolving Credit Borrowings and all outstanding
Swingline Loans on the date of such termination. In the event of any partial
reduction of the Revolving Credit Commitments, then (i) at or prior to the
effective date of such reduction, the Administrative Agent shall notify the
Borrower and the Revolving Credit Lenders of the Aggregate Revolving Credit
Exposure after giving effect thereto and (ii) if such Aggregate Revolving Credit
Exposure would exceed the Total Revolving Credit Commitment after giving effect
to such reduction or termination, then the Borrower shall, on the date of such
reduction or termination, repay or prepay Revolving Credit Borrowings or
Swingline Loans (or a combination thereof) in an amount sufficient to eliminate
such excess. If following any reduction of the Total Revolving Credit Commitment
and the payments required by this Section 2.13(a), the Total Revolving Credit
Commitment is less than the aggregate L/C Exposure, the Borrower shall, on the
date of such reduction, provide cash collateral, in accordance with Section
2.23(j), in an amount equal to the amount that the aggregate L/C Exposure
exceeds the Total Revolving Credit Commitment.

         (b) Not later than the third Business Day following the later of (i)
the completion of any Asset Sale and (ii) the receipt of the Net Cash Proceeds
with respect thereto, the Borrower shall apply 100% of the Net Cash Proceeds
received with respect thereto to prepay outstanding Term Loans in accordance
with Section 2.13(g).
<PAGE>   38
                                                                              33

         (c) Not later than the third Business Day following receipt of any
Extraordinary Amount, the Borrower shall apply 100% of such Extraordinary Amount
received to prepay outstanding Term Loans in accordance with Section 2.13(g).

         (d) In the event and on each occasion that an Equity Issuance occurs,
the Borrower shall, substantially simultaneously with (and in any event not
later than the third Business Day next following) the occurrence of such Equity
Issuance, apply 50% of the Net Cash Proceeds therefrom to prepay outstanding
Term Loans in accordance with Section 2.13(g).

         (e) No later than the earlier of (i) 100 days after the end of each
fiscal year of the Borrower, commencing with the fiscal year ending on December
31, 1997, and (ii) the day that is five Business Days after the date on which
the financial statements with respect to such period are delivered pursuant to
Section 5.04(a), the Borrower shall prepay outstanding Term Loans in accordance
with Section 2.13(g) in an aggregate principal amount equal to 50% of Excess
Cash Flow for the fiscal year then ended; provided, however, that no prepayment
shall be required pursuant to this Section 2.13(e), if the Senior Debt Ratio at
the end of such fiscal year then ended is less than 2.00 to 1.00.

         (f) In the event that Allied, the Borrower or any Subsidiary shall
receive Net Cash Proceeds from the issuance or other disposition of Indebtedness
for money borrowed (other than Indebtedness the issuance of which also
constitutes an Equity Issuance), of Allied, the Borrower or any Subsidiary
(other than Indebtedness for money borrowed permitted pursuant to Section 6.01),
the Borrower shall, substantially simultaneously with (and in any event not
later than the third Business Day next following) the receipt of such Net Cash
Proceeds by Allied, the Borrower or the Subsidiaries, apply an amount equal to
100% of such Net Cash Proceeds to prepay outstanding Term Loans in accordance
with Section 2.13(g).

         (g) Mandatory prepayments of outstanding Term Loans under this
Agreement shall be applied pro rata against the remaining scheduled installments
of principal due in respect of Term Loans under Section 2.11(a).

         (h) The Borrower shall deliver to the Administrative Agent, at the time
of each prepayment required under this Section 2.13, (i) a certificate signed by
a Financial Officer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) to the extent practicable,
at least three days prior written notice of such prepayment. Each notice of
prepayment shall specify the prepayment date, the Type of each Loan being
prepaid and the principal amount of each Loan (or portion thereof) to be
prepaid. All prepayments under this Section 2.13 shall be subject to Section
2.16, but shall otherwise be without premium or penalty.

         (i) Amounts to be applied pursuant to this Section 2.13 to the
prepayment of Term Loans shall be applied, as applicable, first to reduce
outstanding Base Rate Term Loans. Any amounts remaining after each such
application shall, at the option of the Borrower, be applied to prepay
Eurodollar Term Loans immediately and/or shall be deposited in the Prepayment
Account (as defined below). The Administrative Agent shall apply any cash
deposited in the Prepayment Account allocable to Term Loans to prepay Eurodollar
Term Loans on the last day of their respective Interest Periods (or, at the
direction of the Borrower, on any earlier date) until all outstanding Term Loans
have been prepaid or until all the allocable cash on deposit with respect to
such Loans has been exhausted. For purposes of this Agreement, the term
"Prepayment Account" shall mean an account established by the Borrower with the
Administrative Agent and over which the Administrative Agent
<PAGE>   39
                                                                              34

shall have exclusive dominion and control, including the exclusive right of
withdrawal for application in accordance with this paragraph (i). The
Administrative Agent will, at the request of the Borrower, invest amounts on
deposit in the Prepayment Account in Permitted Investments that mature prior to
the last day of the applicable Interest Periods of the Eurodollar Term
Borrowings; provided, however, that (i) the Administrative Agent shall not be
required to make any investment that, in its sole judgment, would require or
cause the Administrative Agent to be in, or would result in any, violation of
any law, statute, rule or regulation and (ii) the Administrative Agent shall
have no obligation to invest amounts on deposit in the Prepayment Account if a
Default or Event of Default shall have occurred and be continuing. The Borrower
shall indemnify the Administrative Agent for any losses relating to the
investments so that the amount available to prepay Eurodollar Borrowings on the
last day of the applicable Interest Period is not less than the amount that
would have been available had no investments been made pursuant thereto. Other
than any interest earned on such investments, the Prepayment Account shall not
bear interest. Interest or profits, if any, on such investments shall be
deposited in the Prepayment Account and reinvested and disbursed as specified
above. If the maturity of the Loans has been accelerated pursuant to Article
VII, the Administrative Agent may, in its sole discretion, apply all amounts on
deposit in the Prepayment Account to satisfy any of the Obligations. The
Borrower hereby grants to the Administrative Agent, for its benefit and the
benefit of the Issuing Bank, the Swingline Lender and the Lenders, a security
interest in the Prepayment Account to secure the Obligations.

         (j) In the event that, upon the occurrence of any event described in
Section 2.13(b), (c), (d), (e) or (f), no Term Loans are outstanding that are
required to be prepaid pursuant to Section 2.13(b), (c), (d), (e) or (f) the
Borrower shall reduce the Revolving Credit Commitments in accordance with
paragraph (a) above by the amount of the applicable Net Cash Proceeds,
Extraordinary Amounts or Excess Cash Flow, as the case may be; provided,
however, that the Total Revolving Credit Commitment shall not be reduced to less
than $300,000,000 as a result of reductions required pursuant to this Section
2.13(j).

         (k) At any time that the Swingline Exposure exceeds $25,000,000, the
Borrower shall repay or prepay outstanding Swingline Loans in an amount
sufficient to eliminate such excess no later than three Business Days after the
date the Borrower has knowledge (actual or constructive) that the Swingline
Exposure exceeds $25,000,000.

         (l) No later than three Business Days after the date that the Revolving
Loan relating to the Canada Debenture Refinancing is borrowed, the Borrower,
Allied and Allied Finance shall cause such Revolving Loan to be repaid or
prepaid in full with the proceeds from repayment of the Allied Canada
Debentures.

         SECTION 2.14. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender or the Issuing
Bank of the principal of or interest on any Eurodollar Loan made by such Lender
or any Fees or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender or the Issuing Bank by
the jurisdiction in which such Lender or the Issuing Bank has its principal
office or by any political subdivision or taxing authority therein), or shall
impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of or credit
<PAGE>   40
                                                                              35

extended by any Lender or the Issuing Bank (except any such reserve requirement
which is reflected in the Adjusted LIBO Rate) or shall impose on such Lender or
the Issuing Bank or the London interbank market any other condition affecting
this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit
or participation therein, and the result of any of the foregoing shall be to
increase the cost to such Lender or the Issuing Bank of making or maintaining
any Eurodollar Loan or increase the cost to any Lender of issuing or maintaining
any Letter of Credit or purchasing or maintaining a participation therein or to
reduce the amount of any sum received or receivable by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise) by an
amount deemed by such Lender or the Issuing Bank to be material, then the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, upon
demand such additional amount or amounts as will compensate such Lender or the
Issuing Bank, as the case may be, for such additional costs incurred or
reduction suffered.

         (b) If any Lender or the Issuing Bank shall have determined that the
adoption after the date hereof of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or any change after the date hereof in any
such law, rule, regulation, agreement or guideline (whether such law, rule,
regulation, agreement or guideline has been adopted) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or the Issuing Bank or any Lender's or the
Issuing Bank's holding company with any request or directive regarding capital
adequacy (whether or not having the force of law) of any Governmental Authority
has or would have the effect of reducing the rate of return on such Lender's or
the Issuing Bank's capital or on the capital of such Lender's or the Issuing
Bank's holding company, if any, as a consequence of this Agreement or the Loans
made or participations in Letters of Credit purchased by such Lender pursuant
hereto or the Letters of Credit issued by the Issuing Bank pursuant hereto to a
level below that which such Lender or the Issuing Bank or such Lender's or the
Issuing Bank's holding company would have achieved but for such applicability,
adoption, change or compliance (taking into consideration such Lender's or the
Issuing Bank's policies and the policies of such Lender's or the Issuing Bank's
holding company with respect to capital adequacy) by an amount deemed by such
Lender or the Issuing Bank to be material, then from time to time the Borrower
shall pay to such Lender or the Issuing Bank, as the case may be, such
additional amount or amounts as will compensate such Lender or the Issuing Bank
or such Lender's or the Issuing Bank's holding company for any such reduction
suffered.

         (c) A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its
holding company, as applicable, as specified in paragraph (a) or (b) above shall
be delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender or the Issuing Bank the amount shown as due on
any such certificate delivered by it within 10 days after its receipt of the
same.

         (d) Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation. The
protection of this Section shall be available to each Lender and the Issuing
Bank regardless of any possible contention of the invalidity or inapplicability
of the law, rule, regulation, agreement, guideline or other change or condition
that shall have occurred or been imposed.

         SECTION 2.15. Change in Legality. (a) Notwithstanding any other
provision of this Agreement, if, after the date hereof, any change in any law or
regulation or in the interpretation thereof
<PAGE>   41
                                                                              36

by any Governmental Authority charged with the administration or interpretation
thereof shall make it unlawful for any Lender to make or maintain any Eurodollar
Loan or to give effect to its obligations as contemplated hereby with respect to
any Eurodollar Loan, then, by written notice to the Borrower and to the
Administrative Agent:

                  (i) such Lender may declare that Eurodollar Loans will not
         thereafter (for the duration of such unlawfulness) be made by such
         Lender hereunder (or be continued for additional Interest Periods and
         Base Rate Loans will not thereafter (for such duration) be converted
         into Eurodollar Loans), whereupon any request for a Eurodollar
         Borrowing (or to convert a Base Rate Borrowing to a Eurodollar
         Borrowing or to continue a Eurodollar Borrowing for an additional
         Interest Period) shall, as to such Lender only, be deemed a request for
         a Base Rate Loan (or a request to continue a Base Rate Loan as such for
         an additional Interest Period or to convert a Eurodollar Loan into a
         Base Rate Loan, as the case may be), unless such declaration shall be
         subsequently withdrawn; and

                  (ii) such Lender may require that all outstanding Eurodollar
         Loans made by it be converted to Base Rate Loans, in which event all
         such Eurodollar Loans shall be automatically converted to Base Rate
         Loans as of the effective date of such notice as provided in paragraph
         (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
Base Rate Loans made by such Lender in lieu of, or resulting from the conversion
of, such Eurodollar Loans.

         (b) For purposes of this Section 2.15, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur as a
consequence of (a) any event, other than a default by such Lender in the
performance of its obligations hereunder, which results in (i) such Lender
receiving or being deemed to receive any amount on account of the principal of
any Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to a Base Rate Loan, or the
conversion of the Interest Period with respect to any Eurodollar Loan, in each
case other than on the last day of the Interest Period in effect therefor, or
(iii) any Eurodollar Loan to be made by such Lender (including any Eurodollar
Loan to be made pursuant to a conversion or continuation under Section 2.10) not
being made after notice of such Loan shall have been given by the Borrower
hereunder (any of the events referred to in this clause (a) being called a
"Breakage Event") or (b) any default in the making of any payment or prepayment
required to be made hereunder. In the case of any Breakage Event, such loss
shall include an amount equal to the excess, as reasonably determined by such
Lender, of (i) its cost of obtaining funds for the Eurodollar Loan that is the
subject of such Breakage Event for the period from the date of such Breakage
Event to the last day of the Interest Period in effect (or that would have been
in effect) for such Loan over (ii) the amount of interest likely to be realized
by such Lender in redeploying the funds released or not utilized by reason of
such Breakage Event for such period. A certificate of any Lender setting forth
any
<PAGE>   42
                                                                              37

amount or amounts which such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the Borrower and shall be conclusive absent
manifest error.

         SECTION 2.17. Pro Rata Treatment. Except as provided below in this
Section 2.17 with respect to Swingline Loans and as required under Section 2.15,
each Borrowing, each payment or prepayment of principal of any Borrowing, each
payment of interest on the Loans, each payment of the Commitment Fees, each
reduction of the Term Loan Commitments or the Revolving Credit Commitments and
each conversion of any Borrowing to or continuation of any Borrowing as a
Borrowing of any Type shall be allocated pro rata among the Lenders in
accordance with their respective applicable Commitments (or, if such Commitments
shall have expired or been terminated, in accordance with the respective
principal amounts of their outstanding Loans). For purposes of determining the
available Revolving Credit Commitments of the Lenders at any time, each
outstanding Swingline Loan shall be deemed to have utilized the Revolving Credit
Commitments of the Lenders (including those Lenders which shall not have made
Swingline Loans) pro rata in accordance with such respective Revolving Credit
Commitments. Each Lender agrees that in computing such Lender's portion of any
Borrowing to be made hereunder, the Administrative Agent may, in its discretion,
round each Lender's percentage of such Borrowing to the next higher or lower
whole dollar amount.

         SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower or any other Loan Party, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, or by
any other means, obtain payment (voluntary or involuntary) in respect of any
Loan or Loans or L/C Disbursement as a result of which the unpaid principal
portion of its Term Loans, Revolving Loans and participations in L/C
Disbursements shall be proportionately less than the unpaid principal portion of
the Term Loans and Revolving Loans and participations in L/C Disbursements of
any other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Term Loans and Revolving Loans and
L/C Exposure, as the case may be of such other Lender, so that the aggregate
unpaid principal amount of the Term Loans and Revolving Loans and L/C Exposure
and participations in Term Loans and Revolving Loans and L/C Exposure held by
each Lender shall be in the same proportion to the aggregate unpaid principal
amount of all Term Loans and Revolving Loans and L/C Exposure then outstanding
as the principal amount of its Term Loans and Revolving Loans and L/C Exposure
prior to such exercise of banker's lien, setoff or counterclaim or other event
was to the principal amount of all Term Loans and Revolving Loans and L/C
Exposure outstanding prior to such exercise of banker's lien, setoff or
counterclaim or other event; provided, however, that if any such purchase or
purchases or adjustments shall be made pursuant to this Section 2.18 and the
payment giving rise thereto shall thereafter be recovered, such purchase or
purchases or adjustments shall be rescinded to the extent of such recovery and
the purchase price or prices or adjustment restored without interest. The
Borrower and Allied expressly consent to the foregoing arrangements and agree
that any Lender holding a participation in a Term Loan or Revolving Loan or L/C
Disbursement deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Borrower and Allied to such Lender by reason thereof as fully as if such
Lender had made a Loan directly to the Borrower in the amount of such
participation.

         SECTION 2.19. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any L/C Disbursement or
any Fees or other amounts) hereunder and
<PAGE>   43
                                                                              38

under any other Loan Document not later than 12:00 (noon), New York City time,
on the date when due in immediately available dollars, without setoff, defense
or counterclaim. Each such payment (other than (i) Issuing Bank Fees, which
shall be paid directly to the Issuing Bank, and (ii) principal of and interest
on Swingline Loans, which shall be paid directly to the Swingline Lender except
as otherwise provided in Section 2.22(e)) shall be made to the Administrative
Agent at its offices at 11 Madison Avenue, New York, New York.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by or on behalf of the
Borrower or any Loan Party hereunder and under any other Loan Document shall be
made, in accordance with Section 2.19, free and clear of and without deduction
for any and all current or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding (i) income
taxes imposed on the net income of the Administrative Agent, the Syndication
Agent, the Documentation Agent, any Lender or the Issuing Bank (or any
transferee or assignee thereof, including a participation holder (any such
entity a "Transferee")) and (ii) franchise taxes imposed on the net income of
the Administrative Agent, the Syndication Agent, the Documentation Agent, any
Lender or the Issuing Bank (or Transferee), in each case by the jurisdiction
under the laws of which the Administrative Agent, the Syndication Agent, the
Documentation Agent, such Lender or the Issuing Bank (or Transferee) is
organized or in which the principal office or applicable lending office of the
Administrative Agent, the Syndication Agent, the Documentation Agent, such
Lender or the Issuing Bank (or Transferee) is located or any political
subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, being
called "Taxes"). If the Borrower or any Loan Party shall be required to deduct
any Taxes from or in respect of any sum payable hereunder or under any other
Loan Document to the Administrative Agent, the Syndication Agent, the
Documentation Agent, any Lender or the Issuing Bank (or any Transferee), (i) the
sum payable shall be increased by the amount (an "additional amount") necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.20) the Administrative Agent, the
Syndication Agent, the Documentation Agent, such Lender or the Issuing Bank (or
Transferee), as the case may be, shall receive an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower or such
Loan Party shall make such deductions and (iii) the Borrower or such Loan Party
shall pay the full amount deducted to the relevant Governmental Authority in
accordance with applicable law.

         (b) In addition, the Borrower agrees to pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies (including, without limitation, mortgage recording taxes and
similar fees) that arise from any payment made hereunder or under any other Loan
Document or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or any other Loan Document ("Other Taxes").

         (c) The Borrower will indemnify the Administrative Agent, the
Syndication Agent, the Documentation Agent, each Lender and the Issuing Bank (or
Transferee) for the full amount of Taxes and Other Taxes paid by the
Administrative Agent, such Lender or the Issuing Bank (or Transferee),
<PAGE>   44
                                                                              39

as the case may be, and any liability (including penalties, interest and
expenses (including reasonable attorney's fees and expenses but excluding
penalties, interest and expenses arising as a result of the gross negligence of
such Lender)) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted by the relevant
Governmental Authority (it being understood that such indemnification shall not
impair any right that the Borrower may have to contest with the relevant
Governmental Authority such Taxes or Other Taxes). A certificate as to the
amount of such payment or liability prepared by the Administrative Agent, the
Syndication Agent, the Documentation Agent, a Lender or the Issuing Bank (or
Transferee), or the Administrative Agent on its behalf, absent manifest error,
shall be final, conclusive and binding for all purposes. Such indemnification
shall be made within 30 days after the date the Administrative Agent, any
Lender, the Syndication Agent, the Documentation Agent, or the Issuing Bank (or
Transferee), as the case may be, makes written demand therefor.

         (d) As soon as practicable after the date of any payment of Taxes or
Other Taxes by the Borrower or any other Loan Party to the relevant Governmental
Authority, the Borrower or such other Loan Party will deliver to the
Administrative Agent, at its address referred to in Section 9.01, the original
or a certified copy of a receipt issued by such Governmental Authority
evidencing payment thereof.

         (e) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within
the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement and the
other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on
or before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before the date such
participation holder becomes a Transferee hereunder) and on or before the date,
if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "New Lending Office"). In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.20(e), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.20(e) that
such Non-U.S. Lender is not legally able to deliver.

         (f) The Borrower shall not be required to indemnify any Non-U.S. Lender
or to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender became a party
to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Lending Office, the date such Non-U.S. Lender
designated such New Lending Office with respect to a Loan;
<PAGE>   45
                                                                              40

provided, however, that this paragraph (f) shall not apply (x) to any Transferee
or New Lending Office that becomes a Transferee or New Lending Office as a
result of an assignment, participation, transfer or designation made at the
request of the Borrower and (y) to the extent the indemnity payment or
additional amounts any Transferee, or any Lender (or Transferee), acting through
a New Lending Office, would be entitled to receive (without regard to this
paragraph (f)) do not exceed the indemnity payment or additional amounts that
the person making the assignment, participation or transfer to such Transferee,
or Lender (or Transferee) making the designation of such New Lending Office,
would have been entitled to receive in the absence of such assignment,
participation, transfer or designation or (ii) the obligation to pay such
additional amounts would not have arisen but for a failure by such Non-U.S.
Lender to comply with the provisions of paragraph (e) above.

         (g) Nothing contained in this Section 2.20 shall require any Lender or
the Issuing Bank (or any Transferee) or the Administrative Agent, the
Syndication Agent or the Documentation Agent to make available any of its tax
returns (or any other information that it deems to be confidential or
proprietary).

         SECTION 2.21. Assignment of Commitments Under Certain Circumstances;
Duty to Mitigate. (a) In the event (i) any Lender or the Issuing Bank delivers a
certificate requesting compensation pursuant to Section 2.14, (ii) any Lender or
the Issuing Bank delivers a notice described in Section 2.15 or (iii) the
Borrower is required to pay any additional amount to any Lender or the Issuing
Bank or any Governmental Authority on account of any Lender or the Issuing Bank
pursuant to Section 2.20, the Borrower may, at its sole expense and effort
(including with respect to the processing and recordation fee referred to in
Section 9.04(b)), upon notice to such Lender or the Issuing Bank and the
Administrative Agent, require such Lender or the Issuing Bank to transfer and
assign, without recourse (in accordance with and subject to the restrictions
contained in Section 9.04), all of its interests, rights and obligations under
this Agreement to an assignee that shall assume such assigned obligations (which
assignee may be another Lender, if a Lender accepts such assignment); provided
that (x) such assignment shall not conflict with any law, rule or regulation or
order of any court or other Governmental Authority having jurisdiction, (y) the
Borrower shall have received the prior written consent of the Administrative
Agent (and, if a Revolving Credit Commitment is being assigned, of the Issuing
Bank and the Swingline Lender), which consent shall not unreasonably be
withheld, and (z) the Borrower or such assignee shall have paid to the affected
Lender or the Issuing Bank in immediately available funds an amount equal to the
sum of the principal of and interest accrued to the date of such payment on the
outstanding Loans or L/C Disbursements of such Lender or the Issuing Bank,
respectively, plus all Fees and other amounts accrued for the account of such
Lender or the Issuing Bank hereunder (including any amounts under Section 2.14
and Section 2.16); provided further that, if prior to the giving of such notice
the circumstances or event that resulted in such Lender's or the Issuing Bank's
claim for compensation under Section 2.14 or notice under Section 2.15 or the
amounts paid pursuant to Section 2.20, as the case may be, cease to cause such
Lender or the Issuing Bank to suffer increased costs or reductions in amounts
received or receivable or reduction in return on capital, or cease to have the
consequences specified in Section 2.15, or cease to result in amounts being
payable under Section 2.20, as the case may be (including as a result of any
action taken by such Lender or the Issuing Bank pursuant to paragraph (b)
below), or if such Lender or the Issuing Bank shall waive its right to claim
further compensation under Section 2.14 in respect of such circumstances or
event or shall withdraw its notice under Section 2.15 or shall waive its right
to further payments under Section 2.20 in respect of such circumstances or
event, as the case may be, then such Lender or the Issuing Bank shall not
thereafter be required to make any such transfer and assignment hereunder.
<PAGE>   46
                                                                              41

         (b) If (i) any Lender or the Issuing Bank shall request compensation
under Section 2.14, (ii) any Lender or the Issuing Bank delivers a notice
described in Section 2.15 or (iii) the Borrower is required to pay any
additional amount to any Lender or the Issuing Bank or any Governmental
Authority on account of any Lender or the Issuing Bank, pursuant to Section
2.20, then such Lender or the Issuing Bank shall use reasonable efforts (which
shall not require such Lender or the Issuing Bank to incur an unreimbursed loss
or unreimbursed cost or expense or otherwise take any action inconsistent with
its internal policies or legal or regulatory restrictions or suffer any
disadvantage or burden deemed by it to be significant) (x) to file any
certificate or document reasonably requested in writing by the Borrower or (y)
to assign its rights and delegate and transfer its obligations hereunder to
another of its offices, branches or affiliates, if such filing or assignment
would reduce its claims for compensation under Section 2.14 or enable it to
withdraw its notice pursuant to Section 2.15 or would reduce amounts payable
pursuant to Section 2.20, as the case may be, in the future. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender or the
Issuing Bank in connection with any such filing or assignment, delegation and
transfer.

         SECTION 2.22. Swingline Loans. (a) Swingline Commitment. Subject to the
terms and conditions and relying upon the representations and warranties herein
set forth, the Swingline Lender agrees to make loans to the Borrower at any time
and from time to time on and after the Closing Date and until the earlier of the
Maturity Date and the termination of the Revolving Credit Commitments in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in (i) the aggregate principal amount of all
Swingline Loans exceeding $50,000,000 or (ii) the Aggregate Revolving Credit
Exposure, after giving effect to any Swingline Loan, exceeding the Total
Revolving Credit Commitment. Each Swingline Loan shall be in a minimum principal
amount of $1,000,000 that is an integral multiple of $250,000. The Swingline
Commitment may be terminated or reduced from time to time as provided herein.
Within the foregoing limits, the Borrower may borrow, pay or prepay and reborrow
Swingline Loans hereunder, subject to the terms, conditions and limitations set
forth herein.

         (b) Swingline Loans. The Borrower shall notify the Administrative Agent
by telecopy, or by telephone (confirmed by telecopy), not later than 1:00 p.m.,
New York City time, on the day of a proposed Swingline Loan. Such notice shall
be delivered on a Business Day, shall be irrevocable and shall refer to this
Agreement and shall specify the requested date (which shall be a Business Day)
and amount of such Swingline Loan. The Administrative Agent will promptly advise
the Swingline Lender of any notice received from the Borrower pursuant to this
paragraph (b). The Swingline Lender shall make each Swingline Loan available to
the Borrower by means of a credit to an account in the name of the Borrower
designated by the Borrower by 3:00 p.m. on the date such Swingline Loan is so
requested.

         (c) Prepayment. The Borrower shall have the right at any time and from
time to time to prepay any Swingline Loan, in whole or in part, upon giving
written or telecopy notice (or telephone notice promptly confirmed by written,
or telecopy notice) to the Swingline Lender and to the Administrative Agent
before 12:00 (noon), New York City time on the date of prepayment at the
Swingline Lender's address for notices specified on Schedule 2.01. All principal
payments of Swingline Loans shall be accompanied by accrued interest on the
principal amount being repaid, but not including, to the date of payment.

         (d) Interest. Each Swingline Loan shall be a Base Rate Loan and,
subject to the provisions of Section 2.07, shall bear interest as provided in
Section 2.06(a).
<PAGE>   47
                                                                              42

         (e) Participations. The Swingline Lender may by written notice given to
the Administrative Agent not later than 1:00 p.m., New York City time, on any
Business Day require the Revolving Credit Lenders to acquire participations on
such Business Day in all or a portion of the Swingline Loans outstanding. Such
notice shall specify the aggregate amount of Swingline Loans in which Revolving
Credit Lenders will participate. The Administrative Agent will, promptly upon
receipt of such notice, give notice to each Revolving Credit Lender, specifying
in such notice such Lender's Pro Rata Percentage of such Swingline Loan or
Loans. In furtherance of the foregoing, each Revolving Credit Lender hereby
absolutely and unconditionally agrees, upon receipt of notice as provided above,
to pay to the Administrative Agent, for the account of the Swingline Lender,
such Revolving Credit Lender's Pro Rata Percentage of such Swingline Loan or
Loans. Each Revolving Credit Lender acknowledges and agrees that its obligation
to acquire participations in Swingline Loans pursuant to this paragraph is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including the occurrence and continuance of a Default or an Event of
Default, and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever. Each Revolving Credit Lender shall comply
with its obligation under this paragraph by wire transfer of immediately
available funds, in the same manner as provided in Section 2.02(c) with respect
to Loans made by such Lender (and Section 2.02(c) shall apply, mutatis mutandis,
to the payment obligations of the Lenders) and the Administrative Agent shall
promptly pay to the Swingline Lender the amounts so received by it from the
Lenders. The Administrative Agent shall notify the Borrower of any
participations in any Swingline Loan acquired pursuant to this paragraph and
thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by
the Swingline Lender from the Borrower (or other party on behalf of the
Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender
of the proceeds of a sale of participations therein shall be promptly remitted
to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Lenders that
shall have made their payments pursuant to this paragraph and to the Swingline
Lender, as their interests may appear. The purchase of participations in a
Swingline Loan pursuant to this paragraph shall not relieve the Borrower (or
other party liable for obligations of the Borrower) of any default in the
payment thereof.

         SECTION 2.23. Letters of Credit. (a) General. The Borrower may request
the issuance of a Letter of Credit for its own account or the account of any
other Account Party (provided that the Borrower shall be a co-applicant and
co-obligor with respect to each Letter of Credit issued for the account of any
other Account Party), in a form reasonably acceptable to the Administrative
Agent and the Issuing Bank, at any time and from time to time while the
Revolving Credit Commitments remain in effect. This Section shall not be
construed to impose an obligation upon the Issuing Bank to issue any Letter of
Credit that is inconsistent with the terms and conditions of this Agreement.

         (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. In order to request the issuance of a Letter of Credit (or to amend,
renew or extend an existing Letter of Credit), the Borrower shall hand deliver
or telecopy to the Issuing Bank and the Administrative Agent (reasonably in
advance of the requested date of issuance, amendment, renewal or extension) a
notice requesting the issuance of a Letter of Credit, or identifying the Letter
of Credit to be amended, renewed or extended, the date of issuance, amendment,
renewal or extension, the date on which such Letter of Credit is to expire
(which shall comply with paragraph (c) below), the amount of such Letter of
Credit, the name and address of the beneficiary thereof and such other
information as shall be necessary to prepare such Letter of Credit. Following
receipt of such notice and prior to the issuance of the requested Letter of
Credit or the applicable amendment, renewal or extension, the
<PAGE>   48
                                                                              43

Administrative Agent shall notify the Issuing Bank of the amount of the
Aggregate Revolving Credit Exposure after giving effect to (i) the issuance,
amendment, renewal or extension of such Letter of Credit, (ii) the issuance or
expiration of any other Letter of Credit that is to be issued or will expire
prior to the requested date of issuance of such Letter of Credit and (iii) the
borrowing or repayment of any Revolving Credit Loans or Swingline Loans that
(based upon notices delivered to the Administrative Agent by the Borrower) are
to be borrowed or repaid prior to the requested date of issuance of such Letter
of Credit. A Letter of Credit shall be issued, amended, renewed or extended only
if, and upon issuance, amendment, renewal or extension of each Letter of Credit
the Borrower shall be deemed to represent and warrant that, after giving effect
to such issuance, amendment, renewal or extension (A) the L/C Exposure shall not
exceed $175,000,000 and (B) the Aggregate Revolving Credit Exposure shall not
exceed the Total Revolving Credit Commitment.

         (c) Expiration Date. Each Letter of Credit shall expire at the close of
business on the date one year after the date of the issuance of such Letter of
Credit (other than any Back-up Letter of Credit, which shall expire on the
expiry date of the letter of credit that such Back-up Letter of Credit supports,
as set forth on Schedule 1.01(a)), unless such Letter of Credit expires by its
terms on an earlier date; provided, however, that each Letter of Credit may,
upon the request of the Borrower, include a provision whereby such Letter of
Credit shall be renewed automatically for additional consecutive periods 12
months or less unless the Issuing Bank notifies the beneficiary thereof not more
than 45, nor fewer than 30, days prior to the then applicable expiry date (or
such other notification periods as set forth in the Back-up Letters of Credit as
set forth on Schedule 1.01(a)) that such Letter of Credit will not be renewed;
provided further, however, that no Letter of Credit may expire or be extended
beyond the date that is five Business Days prior to the Maturity Date unless, on
or prior to the date such Letter of Credit is issued or extended, the Borrower
shall have deposited with the Collateral Agent an amount equal to 110% of the
face amount of such Letter of Credit in a cash collateral account established
with the Collateral Agent for the benefit of the Secured Parties.

         (d) Participations. By the issuance of a Letter of Credit and without
any further action on the part of the Issuing Bank or the Lenders, the Issuing
Bank hereby grants to each Revolving Credit Lender, and each such Lender hereby
acquires from the applicable Issuing Bank, a participation in such Letter of
Credit equal to such Lender's Pro Rata Percentage of the aggregate amount
available to be drawn under such Letter of Credit, effective upon the issuance
of such Letter of Credit. In addition, the Issuing Bank hereby grants to each
Lender, and each Lender hereby acquires from the Issuing Bank, a participation
in each Existing Letter of Credit equal to such Lender's Pro Rata Percentage of
the face amount of such Existing Letter of Credit, effective on the Closing
Date. In consideration and in furtherance of the foregoing, each Revolving
Credit Lender hereby absolutely and unconditionally agrees to pay to the
Administrative Agent, for the account of the Issuing Bank, such Lender's Pro
Rata Percentage of each L/C Disbursement made by the Issuing Bank and not
reimbursed by the applicable Account Party (or, if applicable, another party
pursuant to its obligations under any other Loan Document) forthwith on the date
due as provided in Section 2.02(f). Each Revolving Credit Lender acknowledges
and agrees that its obligation to acquire participations pursuant to this
paragraph in respect of Letters of Credit is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or an Event of Default, and that each such payment
shall be made without any offset, abatement, withholding or reduction
whatsoever.

         (e) Reimbursement. If the Issuing Bank shall make any L/C Disbursement
in respect of a Letter of Credit, the applicable Account Party shall pay to the
Administrative Agent an amount equal
<PAGE>   49
                                                                              44

to such L/C Disbursement not later than two hours after such Account Party shall
have received notice from the Issuing Bank that payment of such draft will be
made, or, if such Account Party shall have received such notice later than 10:00
a.m., New York City time, on any Business Day, not later than 10:00 a.m., New
York City time, on the immediately following Business Day.

         (f) Obligations Absolute. Each Account Party's obligations to reimburse
L/C Disbursements as provided in paragraph (e) above shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement, under any and all circumstances whatsoever,
and irrespective of:

                  (i) any lack of validity or enforceability of any Letter of
         Credit or any Loan Document, or any term or provision therein;

                  (ii) any amendment or waiver of or any consent to departure
         from all or any of the provisions of any Letter of Credit or any Loan
         Document;

                  (iii) the existence of any claim, setoff, defense or other
         right that the Account Party, any other party guaranteeing, or
         otherwise obligated with, the Account Party, any Subsidiary or other
         Affiliate thereof or any other person may at any time have against the
         beneficiary under any Letter of Credit, the Issuing Bank, the
         Administrative Agent or any Lender or any other person, whether in
         connection with this Agreement, any other Loan Document or any other
         related or unrelated agreement or transaction;

                  (iv) any draft or other document presented under a Letter of
         Credit proving to be forged, fraudulent, invalid or insufficient in any
         respect or any statement therein being untrue or inaccurate in any
         respect;

                  (v) payment by the Issuing Bank under a Letter of Credit
         against presentation of a draft or other document that does not comply
         with the terms of such Letter of Credit; and

                  (vi) any other act or omission to act or delay of any kind of
         the Issuing Bank, the Lenders, the Administrative Agent or any other
         person or any other event or circumstance whatsoever (other than
         payment against presentation of drafts or documents that, as a result
         of the Issuing Bank's negligence, do not comply with the terms of such
         Letter of Credit), whether or not similar to any of the foregoing, that
         might, but for the provisions of this Section, constitute a legal or
         equitable discharge of the Account Party's obligations hereunder.

         Without limiting the generality of the foregoing, it is expressly
understood and agreed that the absolute and unconditional obligation of each
Account Party hereunder to reimburse L/C Disbursements will not be excused by
the gross negligence or wilful misconduct of the Issuing Bank. However, the
foregoing shall not be construed to excuse the Issuing Bank from liability to
such Account Party to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the
Borrower, Allied and the other Account Parties to the extent permitted by
applicable law) suffered by such Account Party that are caused by the Issuing
Bank's gross negligence or wilful misconduct in determining whether drafts and
other documents presented under a Letter of Credit comply with the terms
thereof; it is understood that the Issuing Bank may accept documents that appear
on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary and, in making any
payment

                                                                              45

under any Letter of Credit (i) the Issuing Bank's exclusive reliance on the
documents presented to it under such Letter of Credit as to any and all matters
set forth therein, including reliance on the amount of any draft presented under
such Letter of Credit, whether or not the amount due to the beneficiary
thereunder equals the amount of such draft and whether or not any document
presented pursuant to such Letter of Credit proves to be insufficient in any
respect, if such document on its face appears to be in order, and whether or not
any other statement or any other document presented pursuant to such Letter of
Credit proves to be forged or invalid or any statement therein proves to be
inaccurate or untrue in any respect whatsoever and (ii) any noncompliance in any
immaterial respect of the documents presented under such Letter of Credit with
the terms thereof shall, in each case, be deemed not to constitute wilful
misconduct or gross negligence of the Issuing Bank.

         (g) Disbursement Procedures. The Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Issuing Bank shall as promptly as possible
give telephonic notification, confirmed by telecopy, to the Administrative Agent
and the applicable Account Party of such demand for payment and whether the
Issuing Bank has made or will make an L/C Disbursement thereunder; provided that
any failure to give or delay in giving such notice shall not relieve the Account
Party of its obligation to reimburse the Issuing Bank and the Revolving Credit
Lenders with respect to any such L/C Disbursement. The Administrative Agent
shall promptly give each Revolving Credit Lender notice thereof if the
applicable Account Party does not pay the applicable reimbursement amount in
accordance with paragraph (e) above.

         (h) Interim Interest. If the Issuing Bank shall make any L/C
Disbursement in respect of a Letter of Credit, then, unless the applicable
Account Party shall reimburse such L/C Disbursement in full on such date, the
unpaid amount thereof shall bear interest for the account of the Issuing Bank,
for each day from and including the date of such L/C Disbursement, to but
excluding the earlier of the date of payment by the applicable Account Party or
the date on which interest shall commence to accrue thereon as provided in
Section 2.02(f), at the rate per annum that would apply to such amount if such
amount were a Base Rate Loan.

         (i) Resignation or Removal of the Issuing Bank. The Issuing Bank may
resign at any time by giving 180 days' prior written notice to the
Administrative Agent, the Lenders and the Borrower, and may be removed at any
time by the Borrower by notice to the Issuing Bank, the Administrative Agent and
the Lenders. Subject to the next succeeding paragraph, upon the acceptance of
any appointment as the Issuing Bank hereunder by a Lender that shall agree to
serve as successor Issuing Bank, such successor shall succeed to and become
vested with all the interests, rights and obligations of the retiring Issuing
Bank and the retiring Issuing Bank shall be discharged from its obligations to
issue additional Letters of Credit hereunder. At the time such removal or
resignation shall become effective, the Borrower shall pay all accrued and
unpaid fees pursuant to Section 2.05(c)(ii). The acceptance of any appointment
as the Issuing Bank hereunder by a successor Lender shall be evidenced by an
agreement entered into by such successor, in a form satisfactory to the Borrower
and the Administrative Agent, and, from and after the effective date of such
agreement, (i) such successor Lender shall have all the rights and obligations
of the previous Issuing Bank under this Agreement and the other Loan Documents
and (ii) references herein and in the other Loan Documents to the term "Issuing
Bank" shall be deemed to refer to such successor or to any previous Issuing
Bank, or to such successor and all previous Issuing Banks, as the context shall
require. After the resignation or removal of the Issuing Bank hereunder, the
retiring Issuing Bank shall remain a party hereto and shall continue to have all
the rights and obligations of an Issuing Bank under this Agreement and the other
Loan
<PAGE>   51
                                                                              46

Documents with respect to Letters of Credit issued by it prior to such
resignation or removal, but shall not be required to issue additional Letters of
Credit.

         The Administrative Agent shall, at the reasonable request of the
Borrower, appoint a Lender to issue a specific Letter of Credit under this
Agreement in accordance with the terms hereof, provided that such appointment
shall in no way be deemed a resignation or removal of the Issuing Bank under
this Agreement. Such appointment shall be subject to the consent of the
applicable Lender. Unless the context otherwise requires, references herein and
in the other Loan Documents to the term Issuing Bank shall refer to the Issuing
Bank hereunder and such Lender appointed by the Administrative Agent to issue a
Letter of Credit.

         (j) Cash Collateralization. If any Event of Default shall occur and be
continuing, or if the Total Revolving Credit Commitment is less than the
aggregate L/C Exposure, the Borrower shall, on the Business Day following which
it receives notice from the Administrative Agent or the Required Lenders (or, if
the maturity of the Loans has been accelerated, Revolving Credit Lenders holding
participations in outstanding Letters of Credit representing greater than 50% of
the aggregate undrawn amount of all outstanding Letters of Credit) thereof and
of the amount to be deposited, deposit in an account with the Collateral Agent,
for the benefit of the Revolving Credit Lenders, an amount in cash equal to the
L/C Exposure as of such date. Such deposit shall be held by the Collateral Agent
as collateral for the payment and performance of the Obligations. The Collateral
Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such account. Other than any interest earned on the
investment of such deposits in Permitted Investments, which investments shall be
made at the option and sole discretion of the Collateral Agent, such deposits
shall not bear interest. Interest or profits, if any, on such investments shall
accumulate in such account. Moneys in such account shall (i) automatically be
applied by the Administrative Agent to reimburse the Issuing Bank for L/C
Disbursements (and all accrued interest thereon) for which it has not been
reimbursed, (ii) be held for the satisfaction of the reimbursement obligations
of the Borrower for the L/C Exposure at such time and (iii) if the maturity of
the Loans has been accelerated (but subject to the consent of Revolving Credit
Lenders holding participations in outstanding Letters of Credit representing
greater than 50% of the aggregate undrawn amount of all outstanding Letters of
Credit), be applied to satisfy the Obligations. If the Borrower is required to
provide an amount of cash collateral hereunder as a result of the occurrence of
an Event of Default, such amount (to the extent not applied as aforesaid) shall
be returned to the Borrower within three Business Days after all Events of
Default have been cured or waived. If the Borrower is required to provide an
amount of cash collateral hereunder pursuant to Section 2.13(a), such amount
shall be returned to the Borrower from time to time to the extent that the
amount of such cash collateral held by the Collateral Agent exceeds the excess,
if any, of the aggregate L/C Exposure over the Total Revolving Credit
Commitment; provided, that such return shall not be required at any time that an
Event of Default has occurred and is continuing.

Such financial statements present fairly in all material respects the financial

consolidated Subsidiaries as of such dates and for such periods. Such financial

         SECTION 3.06. No Material Adverse Change. There has been no material
adverse change in the business, assets, operations, prospects, condition,
financial or otherwise, or material agreements of Allied, the Borrower and the
Subsidiaries, taken as a whole, since December 31, 1996.

         SECTION 3.07. Title to Properties; Possession Under Leases. (a) Each of
Allied, the Borrower and the Subsidiaries has good and indefeasible title to, or
valid leasehold interests in, all its material properties and assets, except for
minor defects in title that do not materially interfere with its ability to
conduct its business as currently conducted or to utilize such properties and
assets for their intended purposes. All such material properties and assets are
free and clear of Liens, other than Liens expressly permitted by Section 6.02.

         (b) Each of Allied, the Borrower and the Subsidiaries has complied with
all obligations under all material leases to which it is a party and all such

expected to have a Material Adverse Effect.

         SECTION 3.08. Subsidiaries. Schedule 3.08 sets forth as of the Closing
Date a list of all Subsidiaries. Each such Subsidiary is a wholly owned
Subsidiary except as otherwise indicated on Schedule 3.08. The shares of capital

free and clear of all Liens (other than Liens permitted by this Agreement).

         SECTION 3.09. Litigation; Compliance with Laws. (a) Except as set forth
on Schedule 3.09, there are not any actions, suits or proceedings at law or in

the Borrower or any Subsidiary or any business, property or rights of any such
person (i) that involve any Loan Document or the Transactions or (ii) as to
which there is a reasonable possibility of an adverse determination and that,
if adversely determined, could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect.

         (b) None of Allied, the Borrower or any of the Subsidiaries or any of
their respective material properties or assets is in violation of, nor will the
continued operation of their material properties and assets as currently
conducted violate, any law, rule or regulation (including any zoning, building,

         SECTION 3.10. Agreements. (a) None of Allied, the Borrower or any of

assets are or may be bound, where such default could reasonably be expected to
result in a Material Adverse Effect.

         (c) The Borrower is permitted to borrow up to the lesser of (i)
$80,000,000 and (ii) the Additional Facility Amount in reliance upon Section
1008(ix) of the Senior Subordinated Notes Indenture, and all Loans made
hereunder and Letters of Credit issued hereunder are "Senior Debt" as such term
is defined in the Senior Subordinated Notes Indenture.

         SECTION 3.11. Federal Reserve Regulations. (a) None of Allied, the
Borrower or any of the Subsidiaries is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
buying or carrying Margin Stock.

         (b) No part of the proceeds of any Loan or any Letter of Credit will be
used, whether directly or indirectly, and whether immediately, incidentally or
ultimately, for any purpose that entails a violation of, or that is inconsistent
with, the provisions of the Regulations of the Board, including Regulation G, T,
U or X.

         SECTION 3.12. Investment Company Act; Public Utility Holding Company

         SECTION 3.14. Tax Returns. Each of Allied, the Borrower and the
Subsidiaries has filed or caused to be filed all Federal, state and other
material tax returns or materials required to have been filed by it and has paid

appropriate proceedings and for which Allied, the Borrower or such Subsidiary,
as applicable, shall have set aside on its books adequate reserves.

         SECTION 3.15. No Material Misstatements. None of (a) the Confidential
Information Memorandum or (b) any other information, report, financial
statement, exhibit or schedule furnished by or on behalf of Allied or the

Agent or any Lender in connection with the negotiation of any Loan Document or
included therein or delivered pursuant thereto contained, contains or will
contain any material misstatement of fact or omitted, omits or will omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were, are or will be made, not misleading;
provided that to the extent any such information, report, financial statement,
exhibit or
<PAGE>   55
                                                                              50

schedule was based upon or constitutes a forecast, projection or expressions of
opinion, each of Allied and the Borrower represents only that it acted in good
faith and utilized reasonable assumptions and due care in the preparation of
such information, report, financial statement, exhibit or schedule.

         SECTION 3.16. Employee Benefit Plans. Each of the Borrower and its
ERISA Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder, except where non-compliance could not reasonably be
expected to have a Material Adverse Effect. No ERISA Event has occurred or is
reasonably expected to occur that, when taken together with all other such ERISA
Events, could reasonably be expected to result in material liability of the
Borrower or any of its ERISA Affiliates, except where such liability could not
reasonably be expected to have a Material Adverse Effect. The present value of
all benefit liabilities under each Plan (based on those assumptions used to fund
such Plan) did not, as of the last annual valuation date applicable thereto,
exceed by more than $3,000,000 the fair market value of the assets of such Plan,
and the present value of all benefit liabilities of all underfunded Plans (based
on those assumptions used to fund each such Plan) did not, as of the last annual
valuation dates applicable thereto, exceed by more than $3,000,000 fair market
value of the assets of all such underfunded Plans.

         SECTION 3.17. Environmental Matters. Except as set forth in Schedule
3.17:

         (a) The facilities and properties owned, leased or operated by Allied,
the Borrower and the Subsidiaries (the "Properties") do not contain, and have
not previously contained, to the Borrower's best knowledge (actual or
constructive) any Hazardous Materials in amounts or concentrations which (i)
constitute, or constituted a violation of, (ii) require Remedial Action under,
or (iii) could give rise to liability under, Environmental Laws, which
violations, Remedial Actions and liabilities, in the aggregate, could reasonably
be expected to result in a Material Adverse Effect;

         (b) The Properties and all operations of the Borrower and the
Subsidiaries are in compliance, and in the last five years have been in
compliance, with all Environmental Laws and all necessary Environmental Permits
have been obtained and are in effect, except to the extent that such
non-compliance or failure to obtain any necessary permits, in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect;

         (c) There have been no Releases or threatened Releases at, from, under
or proximate to the Properties or otherwise in connection with the operations of
the Borrower or the Subsidiaries, which Releases or threatened Releases, in the
aggregate, could reasonably be expected to result in a Material Adverse Effect;

         (d) None of Allied, the Borrower or any of the Subsidiaries has
received any notice of an Environmental Claim in connection with the Properties
or the operations of the Borrower or the Subsidiaries or with regard to any
person whose liabilities for environmental matters Allied, the Borrower or the
Subsidiaries has retained or assumed, in whole or in part, contractually, by
operation of law or otherwise, which, in the aggregate, could reasonably be
expected to result in a Material Adverse Effect, nor do Allied, the Borrower or
the Subsidiaries have reason to believe that any such notice will be received or
is being threatened; and

         (e) Hazardous Materials have not been transported from the Properties,
nor have Hazardous Materials been generated, treated, stored or disposed of at,
on or under any of the Properties in a
<PAGE>   56
                                                                              51

manner that could give rise to liability under any Environmental Law, nor have
the Borrower or the Subsidiaries retained or assumed any liability,
contractually, by operation of law or otherwise, with respect to the generation,
treatment, storage or disposal of Hazardous Materials, which transportation,
generation, treatment, storage or disposal, or retained or assumed liabilities,
in the aggregate, could reasonably be expected to result in a Material Adverse
Effect.

         SECTION 3.18. Insurance. Schedule 3.18 sets forth a true, complete and
correct description of all insurance maintained by Allied, the Borrower or by
Allied or the Borrower for its Subsidiaries as of the date hereof and the
Closing Date. As of each such date, such insurance is in full force and effect
and all premiums have been duly paid. Allied, the Borrower and its Subsidiaries
have insurance in such amounts and covering such risks and liabilities as are in
accordance with normal industry practice.

         SECTION 3.19. Security Documents. (a) On and after the Closing Date,
each of the Pledge Agreement and the Allied Finance Pledge Agreement will be
effective to create in favor of the Collateral Agent, for the ratable benefit of
the Secured Parties, a legal, valid and enforceable security interest in the
Collateral (as defined in the Pledge Agreement and the Allied Finance Pledge
Agreement, as applicable) and, when the certificates evidencing the investment
securities that constitute the Pledged Securities (as defined in the Pledge
Agreement and the Allied Finance Pledge Agreement, as applicable) are delivered
to the Collateral Agent, the Collateral Agent shall have a fully perfected first
priority Lien on, and security interest in, all right, title and interest of the
pledgors thereunder in such Collateral, in each case prior and superior in right
to any other person.

         (b) On and after the Closing Date, the Security Agreement will be
effective to create in favor of the Collateral Agent, for the ratable benefit of
the Secured Parties, a legal, valid and enforceable security interest in the
Collateral (as defined in the Security Agreement) and, when financing statements
in appropriate form are filed in the offices specified in the Perfection
Schedule, the Security Agreement shall constitute a fully perfected Lien on, and
security interest in, all right, title and interest of the grantors thereunder
in all such Collateral in which a security interest may be perfected by filing,
each case prior and superior in right to any other person, other than with
respect to Liens expressly permitted by Section 6.02.

         SECTION 3.20. Labor Matters. As of the date hereof and the Closing
Date, there are no strikes, lockouts or slowdowns against Allied, the Borrower
or any Subsidiary pending or, to the knowledge of Allied or the Borrower,
threatened, which could reasonably be expected to result in a Material Adverse
Effect. The hours worked by and payments made to employees of Allied, the
Borrower and the Subsidiaries have not been in violation of the Fair Labor
Standards Act or any other applicable Federal, state, local or foreign law
dealing with such matters, which could reasonably be expected to result in a
Material Adverse Effect. All payments due from Allied, the Borrower or any
Subsidiary, or for which any claim may be made against Allied, the Borrower or
any Subsidiary, on account of wages and employee health and welfare insurance
and other benefits, have been paid or accrued as a liability on the books of
Allied, the Borrower or such Subsidiary, except where the failure to do so could
not reasonably be expected to result in a Material Adverse Effect. The
consummation of the Transactions will not give rise to any right of termination
or right of renegotiation on the part of any union under any collective
bargaining agreement to which Allied, the Borrower or any Subsidiary is bound,
except where such event could not reasonably be expected to result in a Material
Adverse Effect.
<PAGE>   57
                                                                              52

         SECTION 3.21. Solvency. Immediately after the consummation of the
Transactions to occur on the Closing Date and immediately following the making
of each Loan made on the Closing Date and after giving effect to the application
of the proceeds of such Loans, and taking into account all rights of indemnity,
subrogation and contribution of the Loan Parties under applicable law and under
the Indemnity, Subrogation and Contribution Agreement, (i) the fair value of the
assets of Allied, the Borrower and the other Loan Parties, on a consolidated
basis, at a fair valuation, will exceed its debts and liabilities, subordinated,
contingent or otherwise; (ii) the present fair saleable value of the property of
Allied, the Borrower and the other Loan Parties, on a consolidated basis, will
be greater than the amount that will be required to pay the probable liability
of its debts and other liabilities, subordinated, contingent or otherwise, as
such debts and other liabilities become absolute and matured; (iii) Allied, the
Borrower and the other Loan Parties, on a consolidated basis, will be able to
pay its debts and liabilities, subordinated, contingent or otherwise, as such
debts and liabilities become absolute and matured; and (iv) Allied, the Borrower
and the other Loan Parties, on a consolidated basis, will not have unreasonably
small capital with which to conduct the business in which it is engaged as such
business is now conducted and is proposed to be conducted following the Closing
Date.


                                   ARTICLE IV

                              Conditions of Lending

         The obligations of the Lenders to make Loans and of the Issuing Bank to
issue Letters of Credit hereunder (each such event being called a "Credit
Event") are subject to the satisfaction of the following conditions:

         (a) The Administrative Agent shall have received a notice of such
Borrowing as required by Section 2.03 (or such notice shall have been deemed
given in accordance with Section 2.03) or, in the case of the issuance,
amendment, renewal or extension of a Letter of Credit, the Issuing Bank and the
Administrative Agent shall have received a notice requesting the issuance,
amendment, renewal or extension of such Letter of Credit as required by Section
2.23(b) or, in the case of the Borrowing of a Swingline Loan, the Swingline
Lender and the Administrative Agent shall have received a notice requesting such
Swingline Loan as required by Section 2.22(b).

         (b) Except in the case of a Borrowing that does not increase the
aggregate principal amount of Loans outstanding of any Lender, the
representations and warranties set forth in Article III hereof shall be true and
correct in all material respects on and as of the date of such Credit Event with
the same effect as though made on and as of such date, except to the extent such

                              Affirmative Covenants

         Each of Allied and the Borrower covenants and agrees with each Lender
that so long as this Agreement shall remain in effect and until the Commitments
have been terminated and the principal of and interest on each Loan, all Fees
and all other expenses or amounts payable under any Loan Document shall have
been paid in full and all Letters of Credit have been canceled or have expired
and all amounts drawn thereunder have been reimbursed in full, unless the
Required Lenders shall otherwise consent in writing, each of Allied and the
Borrower will, and will cause each of the Subsidiaries to:

         SECTION 5.01. Existence; Businesses and Properties. (a) Do or cause to
be done all things necessary to preserve, renew and keep in full force and

Administrative Agent, any Subsidiary may terminate its existence.

         (b) Do or cause to be done all things necessary to obtain, preserve,
renew, extend and keep in full force and effect the rights, licenses, permits,

material to the conduct of its business; maintain and operate such business in
substantially the manner in which it is presently conducted and operated; comply
in all material respects with all applicable laws, rules, regulations and
decrees and orders of any Governmental Authority, whether now in effect or
hereafter enacted; and at all times maintain and preserve all property material
to the conduct of such business and keep such property in good repair, working
order and condition and from time to time make, or cause to be made, all needful
and proper repairs, renewals, additions, improvements and replacements thereto
necessary in order that the business carried on in connection therewith may be
properly conducted at all times.

         SECTION 5.02. Insurance. (a) Keep its insurable properties adequately
insured at all times by financially sound and reputable insurers; maintain such
other insurance, to such extent and against such risks, including fire and other
risks insured against by extended coverage, as is customary with companies in
the same or similar businesses operating in the same or similar locations,
including public liability insurance against claims for personal injury or death
or property damage occurring upon, in, about or in connection with the use of
any properties owned, occupied or controlled by it; and maintain such other
insurance as may be required by law.

         (b) Cause all such policies to be endorsed or otherwise amended to
include a "standard" or "New York" lender's loss payable endorsement, in form
and substance satisfactory to the Administrative Agent and the Collateral Agent,
which endorsement shall provide that, from and after the Closing Date, if the
insurance carrier shall have received written notice from the Administrative
Agent or the Collateral Agent of the occurrence of an Event of Default, the
insurance carrier shall pay all proceeds otherwise payable to the Borrower or
the Loan Parties under such policies directly to the Collateral Agent; cause all
such policies to provide that neither the Borrower, the Administrative Agent,
the Collateral Agent nor any other party shall be a coinsurer thereunder and to
contain a "Replacement Cost Endorsement", without any deduction for
depreciation, and such other provisions as the Administrative Agent or the
Collateral Agent may reasonably require from time to time to protect their
interests; deliver original or certified copies of all such policies to the
Collateral Agent; cause each such policy to provide that it shall not be
canceled, modified or not renewed (i) by reason

of nonpayment of premium upon not less than 10 days' prior written notice
thereof by the insurer to the Administrative Agent and the Collateral Agent
(giving the Administrative Agent and the Collateral Agent the right to cure
defaults in the payment of premiums) or (ii) for any other reason upon not less
than 30 days' prior written notice thereof by the insurer to the Administrative
Agent and the Collateral Agent; deliver to the Administrative Agent and the
Collateral Agent, prior to the cancelation, modification or nonrenewal of any
such policy of insurance, a copy of a renewal or replacement policy (or other
evidence of renewal of a policy previously delivered to the Administrative Agent
and the Collateral Agent) together with evidence satisfactory to the
Administrative Agent and the Collateral Agent of payment of the premium
therefor.

         (c) Notify the Administrative Agent and the Collateral Agent
immediately whenever any separate insurance concurrent in form or contributing
in the event of loss with that required to be maintained under this Section 5.02

obligations promptly and in accordance with their terms and pay and discharge
promptly when due all taxes, assessments and governmental charges or levies
imposed upon it or upon its income or profits or in respect of its property,
before the same shall become delinquent or in default, as well as all lawful
claims for labor, materials and supplies or otherwise that, if unpaid, might
give rise to a Lien upon such properties or any part thereof; provided, however,
that such payment and discharge shall not be required with respect to any such
tax, assessment, charge, levy or claim so long as the validity or amount thereof
shall be contested in good faith by appropriate proceedings and the Borrower
shall have set aside on its books adequate reserves with respect thereto in
accordance with GAAP and such contest operates to suspend collection of the
contested obligation, tax, assessment or charge and enforcement of a Lien.

Borrower, furnish to the Administrative Agent and each Lender:

         year and the results of its operations and the operations of such

         interpretations) (i) certifying that in making its examination in
         connection with rendering such opinion or certificate with respect to
         such statements, such person has not obtained knowledge that an Event

         Governmental Authority, against the Borrower or any Affiliate thereof
         that could reasonably be expected to result in a Material Adverse
         Effect; and

of the Borrower in an aggregate amount exceeding $5,000,000 or (ii) requiring
payments exceeding $2,500,000 in any year, a statement of a Financial Officer of
the Borrower setting forth details as to such ERISA Event and the action, if

representatives designated by the Administrative Agent or any Lender to visit
and inspect the financial records and the properties of Allied, the Borrower or
any Subsidiary at reasonable times and as often as reasonably requested and to
make extracts from and copies of such financial records, and permit any
representatives designated by the Administrative Agent or any Lender to discuss
the affairs, finances and condition of Allied, the Borrower or any Subsidiary
with the officers thereof and independent accountants therefor. Without limiting
the foregoing, the Administrative Agent and its representatives may inspect, and
may cause an environmental assessment to be made of, any real property owned or
leased by Allied, the Borrower or any Subsidiary with a view toward securing the
Obligations by a Lien on such property pursuant to Section 5.11, in each case at
the Borrower's sole cost and expense (not to exceed $100,000 in any fiscal
year).

         SECTION 5.08. Use of Proceeds. Use the proceeds of the Loans and
request the issuance of Letters of Credit only for the purposes set forth in the
preamble to this Agreement.

Properties; obtain and renew all Environmental Permits necessary for its
operations and Properties; and conduct any Remedial Action in accordance with
Environmental Laws, except where such non-compliance or failure to obtain or
renew Environmental Permits or to conduct any Remedial Action could not
reasonably be expected to result in a Material Adverse Effect; provided,
however, that none of Allied, the Borrower or any of the Subsidiaries shall
<PAGE>   62
                                                                              57

be required to undertake any Remedial Action to the extent that any applicable
obligation to do so is being contested in good faith and by proper proceedings
and appropriate reserves are being maintained with respect to such
circumstances.

         (b) With respect to any Permitted Acquisition and any acquisition of
any other ownership or leasehold interest in, or the entry into any agreement to
conduct operations of, any landfill, transfer station or other waste treatment
or disposal facility: (i) prior to consummating any such acquisition or
commencement of any operations under any such agreement or lease, obtain and
review a favorable written assessment, prepared by an environmental consulting
firm recognized within the municipal solid waste industry and among
environmental professionals as competent and reputable and which the Borrower
has reasonably determined to be suitable, that reasonably addresses the
environmental compliance and liability issues associated with the subject of
such acquisition, agreement or lease (an "Environmental Assessment"); and (ii)
furnish such Environmental Assessment to the Administrative Agent promptly
following such acquisition or the commencement of any operations under such an
agreement or lease with respect to a Permitted Acquisition, the total
consideration of which is greater than $5,000,000.

by reason of a breach of Section 3.17 or 5.09 shall have occurred and be
continuing, at the request of the Required Lenders through the Administrative
Agent, provide to the Lenders within 45 days after such request, at the expense
of the Borrower, an environmental site assessment report for the Properties
which are the subject of such default prepared by an environmental consulting
firm acceptable to the Administrative Agent and indicating the presence or
absence of Hazardous Materials and the estimated cost of any compliance or
Remedial Action in connection with such Properties.

         SECTION 5.11. Further Assurances. Execute any and all further
documents, financing statements, agreements and instruments, and take all
further action (including filing Uniform Commercial Code and other financing
statements, mortgages and deeds of trust) that may be required under applicable
law, or that the Required Lenders, the Administrative Agent or the Collateral
Agent may reasonably request, in order to effectuate the transactions
contemplated by the Loan Documents and in order to grant, preserve, protect and
perfect the validity and first priority of the security interests created or
intended to be created by the Security Documents. Allied and the Borrower will
cause any subsequently acquired or organized Subsidiary (other than a Subsidiary
that conducts no operations, has total assets not in excess of $5,000 and has no
Indebtedness) to execute a Subsidiary Guarantee Agreement, Indemnity Subrogation
and Contribution Agreement and each applicable Security Document in favor of the
Collateral Agent, except to the extent any such execution by a Foreign
Subsidiary would have any adverse tax consequences for the Borrower or any of
the Subsidiaries. In addition, from time to time, Allied and the Borrower will,
at their own cost and expense, promptly secure the Obligations by pledging or
creating, or causing to be pledged or created, perfected security interests with
respect to such of its assets and properties (including real property) as the
Administrative Agent or the Required Lenders shall designate (it being
understood that it is the intent of the parties that the Obligations shall be
secured by, among other things, substantially all the assets of Allied and the
Borrower (including real and other properties acquired subsequent to the Closing
Date)). Such security interests and Liens will be created under the Security
Documents and other security agreements, mortgages, deeds of trust and other
instruments and documents in form and substance satisfactory to the Collateral
Agent, and Allied and the Borrower shall deliver or cause to be delivered to the
Collateral Agent all such instruments and documents (including legal opinions,
title insurance policies and lien searches) as the Collateral Agent shall
reasonably request to evidence compliance
<PAGE>   63
                                                                              58

with this Section. Allied and the Borrower agree to provide such evidence as the
Collateral Agent shall reasonably request as to the perfection and priority
status of each such security interest and Lien.

         SECTION 5.12. Compliance with Terms of Leaseholds. Make all payments
and otherwise perform all obligations in respect of all leases of real property
to which Allied, the Borrower or any of the Subsidiaries is a party, keep such
leases in full force and effect and not allow such leases to lapse or be
terminated or any rights to renew such leases to be forfeited or canceled,
notify the Administrative Agent of any default by any party with respect to such
leases and cooperate with the Administrative Agent in all respects to cure any
such default, and cause each of the Subsidiaries to do so, except, in any case,
where the failure to do so, either individually or in the aggregate, could not
be reasonably expected to have a Material Adverse Effect.

         SECTION 5.13. Performance of Material Agreements. Perform and observe
all of the terms and provisions of each agreement that is material to the
conduct of the Borrower's and the Subsidiaries' business to be performed or
observed by it (collectively, the "Material Agreements"), maintain each such
Material Agreement in full force and effect, enforce such Material Agreement in
accordance with its terms, take all action to such end as may be from time to
time requested by the Administrative Agent and, upon request of the
Administrative Agent, make to each other party to each such Material Agreement
such demands and requests for information and reports or for action as Allied or
the Borrower is entitled to make under such Material Agreement, and cause each
of the Subsidiaries to do so, except, in any case, where the failure to do so,
either individually or in the aggregate, could not be reasonably expected to
have a Material Adverse Effect.

         SECTION 5.14. Senior Convertible Debentures. Prior to the end of each
fiscal year, commencing with the fiscal year ending on December 31, 1997, the
Borrower shall deliver to the Administrative Agent evidence reasonably
satisfactory to the Administrative Agent that the Borrower will be in compliance
with the financial covenants of the Senior Convertible Debentures (including
compliance as a result of a waiver or amendment of the terms thereof), provided
that the Borrower shall not be obligated to deliver such evidence if prior to
any such fiscal year-end, the Borrower shall have prepaid all Senior Convertible
Debentures not converted prior to such prepayment, in each case in accordance
with the terms thereof.

         SECTION 5.15. Concentration and Disbursement Accounts. (a) Except to
the extent permitted by paragraph (b) below, the Borrower shall maintain with a
financial institution that is a Lender one or more accounts to be used by the
Borrower as its principal concentration and disbursement accounts and will not,
and will not permit any Subsidiary to, maintain more than an aggregate of
$1,000,000 for more than two Business Days in bank accounts with any person that
is not a Lender.

         (b) Notwithstanding the foregoing, with respect to the accounts of the
Domestic Subsidiaries that were acquired from Laidlaw pursuant to the Stock
Purchase Agreement, (a) the Borrower shall be in compliance with paragraph (a)
within 90 days after the Closing Date. The Borrower and the Subsidiaries shall
be deemed to be in compliance with this Section 5.15 at any time that a lockbox
arrangement in accordance with Section 4.09(b) of the Security Agreement is in
effect.

in full and all Letters of Credit have been canceled or have expired and all
amounts drawn thereunder have been reimbursed in full, unless the Required
Lenders shall otherwise consent in writing, neither Allied nor the Borrower
will, nor will they cause or permit any of the Subsidiaries to:

         hereof and Indebtedness of a corporation merged or consolidated with or
         into the Borrower or a Subsidiary after the date hereof ("Acquired
         Indebtedness"), which Indebtedness in each case exists at the time of
         such acquisition, merger, consolidation or conversion into a Subsidiary
         and is not created in contemplation of such event and where such
         acquisition, merger or consolidation is permitted by this Agreement,
         provided that the Borrower and the Subsidiaries comply with the
         provisions of Section 5.11 with respect to such acquired or newly
         formed Subsidiary;

                  (e) Indebtedness of Allied, the Borrower or any Subsidiary

         Subsidiary to any other wholly owned Subsidiary or the Borrower, so

Credit Suisse First Boston is hereby appointed to act as Administrative Agent
and Collateral Agent on behalf of the Lenders and the Issuing Bank, Goldman

delegated to the Agents by the terms and provisions hereof and of the other Loan
Documents, together with such actions and powers as are reasonably incidental

Lenders hereunder, and promptly to distribute to each Lender or the Issuing Bank
its proper share of each payment so received; (b) to give notice on behalf of
each of the Lenders to the Borrower of any Event of Default specified in this

copies of all notices, financial statements and other materials delivered by the
Borrower or any other Loan Party pursuant to this Agreement or the other Loan
Documents as received by the Administrative Agent. Without limiting the
generality of the foregoing, the Administrative Agent and Collateral Agent are
hereby expressly authorized to execute any and all documents (including
releases) with respect to the Collateral and the rights of the Secured Parties
with respect thereto, as contemplated by and in accordance with the provisions
of this Agreement and the Security Documents.

         Neither the Agents nor any of their respective directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Borrower or any other Loan Party of any of the terms, conditions, covenants or
agreements contained in any Loan Document. The Agents shall not be responsible
to the Lenders for the due execution, genuineness, validity, enforceability or
effectiveness of this Agreement or any other Loan Documents, instruments or
agreements. The Agents shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders. Each Agent shall, in the absence of knowledge to the contrary, be
entitled to rely on any instrument or document believed by it in good faith to
be genuine and correct and to have been signed or sent by the proper person or
persons. Neither the Agents nor any of their respective directors, officers,
employees or agents shall have any responsibility to the Borrower or any other
Loan Party on account of the failure of or delay in performance or breach by any
Lender or the Issuing Bank of any of its obligations hereunder or to any Lender
or the Issuing Bank on account of the failure of or delay in performance or
breach by any other Lender or the Issuing Bank or the Borrower or any other Loan
Party of any of their respective obligations hereunder or under any other Loan
Document or in connection herewith or therewith. Each of the Agents may execute
any and all duties hereunder by or through agents or employees and shall be
entitled to rely upon the advice of legal counsel selected by it with respect to
all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

         The Lenders hereby acknowledge that no Agent shall be under any duty to
take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, any Agent may resign at any time by notifying the Lenders and
the Borrower. Upon any such resignation, the Required Lenders shall have the
right to appoint a successor. If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Agent gives notice of its resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a
bank with an office in New York, New York, having a combined capital and surplus
of at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance

of the retiring Agent and the

retiring Agent shall be discharged from its duties and obligations hereunder.
After the Agent's resignation hereunder, the provisions of this Article and
Section 9.05 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Agent.

         With respect to the Loans made by it hereunder, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not an Agent, and
the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with Allied, the Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent.

         Each Lender agrees to reimburse the Agents and each Revolving Credit
Lender agrees to reimburse the Issuing Bank, in each case, on demand, in the
amount of its pro rata share (based on its Commitments hereunder) of any
expenses incurred for the benefit of the Lenders by the Issuing Bank or the
Agents, as applicable, including counsel fees and compensation of agents and
employees paid for services rendered on behalf of the Lenders or the Revolving
Credit Lenders, as applicable, that shall not have been reimbursed by the
Borrower, and each Lender agrees to indemnify and hold harmless each Agent and
any of their respective directors, officers, employees or agents, and each
Revolving Credit Lender agrees to indemnify and hold harmless the Issuing Bank
and any of its respective directors, officers, employees or agents, in each case
on demand, in the amount of such pro rata share, from and against any and all
liabilities, taxes, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever that
may be imposed on, incurred by or asserted against it in its capacity as the
Issuing Bank or Agent, as applicable, or any of them in any way relating to or
arising out of this Agreement or any other Loan Document or any action taken or
omitted by it or any of them under this Agreement or any other Loan Document, to
the extent the same shall not have been reimbursed by the Borrower or any other
Loan Party, provided that no Lender shall be liable to the Issuing Bank or an
Agent, as applicable, or any such other indemnified person for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of the Issuing Bank or such Agent, as
applicable, or any of their respective directors, officers, employees or agents.

         Each Lender acknowledges that it has, independently and without
reliance upon the Agents or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement or any other Loan Document, any related
agreement or any document furnished hereunder or thereunder.

Bank.

         SECTION 9.03. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Borrower, Allied and the Administrative
Agent, the Syndication Agent and the Documentation Agent and when the
Administrative Agent shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective permitted successors and assigns.

         SECTION 9.04. Successors and Assigns. (a) Whenever in this Agreement
any of the parties hereto is referred to, such reference shall be deemed to
include the permitted successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of the Borrower, Allied, the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Issuing Bank or the Lenders that are contained in this Agreement shall bind and
inure to the benefit of their respective successors and assigns.

         (b) Each Lender may assign to one or more assignees all or a portion of
its interests, rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided,
however, that (i) except in the case of an assignment to a Lender, an Affiliate
of such Lender or a Related Fund, (x) the Borrower (so long as no Event of
Default shall have occurred and be continuing) and the Administrative Agent
(and, in the case of any assignment of a Revolving Credit Commitment, the
Issuing Bank and the Swingline Lender) must give their prior consent to such
assignment (which consent shall not be unreasonably withheld or delayed) and (y)
the amount of the unused Commitment and Loans of the assigning Lender subject to
each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative Agent) shall
not be less than $5,000,000 (or, if less, the entire remaining amount of such
Lender's Commitment) (it being understood that separate assignments that are
made contemporaneously to persons that are Affiliates or a Related Fund shall be
deemed a single assignment for purposes of this sub-clause (y)), (ii) the
parties to each such assignment shall execute and deliver to the Administrative
Agent an Assignment and Acceptance, together with a processing and recordation
fee of $3,500 and (iii) the assignee, if it shall not be a Lender, shall deliver
to the Administrative Agent an Administrative Questionnaire. Upon acceptance and
recording pursuant to paragraph (e) of this Section 9.04, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least five Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and (B) the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.14, 2.16, 2.20 and 9.05, as well as to any Fees accrued for its account and
not yet paid).

         (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and
<PAGE>   81
                                                                              76

the other parties hereto as follows: (i) such assigning Lender warrants that it
is the legal and beneficial owner of the interest being assigned thereby free
and clear of any adverse claim and that its Term Loan Commitment and Revolving
Credit Commitment, and the outstanding balances of its Term Loans and Revolving
Loans, in each case without giving effect to assignments thereof which have not
become effective, are as set forth in such Assignment and Acceptance, (ii)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement, any other Loan Document or any other instrument or
document furnished pursuant hereto, or the financial condition of the Borrower
or any Subsidiary or the performance or observance by the Borrower or any
Subsidiary of any of its obligations under this Agreement, any other Loan
Document or any other instrument or document furnished pursuant hereto; (iii)
such assignee represents and warrants that it is legally authorized to enter
into such Assignment and Acceptance; (iv) such assignee confirms that it has
received a copy of this Agreement, together with copies of the most recent
financial statements referred to in Section 3.05(a) or delivered pursuant to
Section 5.04 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (v) such assignee will independently and without
reliance upon the Administrative Agent, the Syndication Agent, the Documentation
Agent, the Collateral Agent, such assigning Lender or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement; (vi) such assignee appoints and authorizes the Administrative
Agent, the Syndication Agent, the Documentation Agent and the Collateral Agent
to take such action as agent on its behalf and to exercise such powers under
this Agreement as are delegated to the Administrative Agent, the Syndication
Agent, the Documentation Agent and the Collateral Agent, respectively, by the
terms hereof, together with such powers as are reasonably incidental thereto;
and (vii) such assignee agrees that it will perform in accordance with their
terms all the obligations which by the terms of this Agreement are required to
be performed by it as a Lender.

         (d) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive and the Borrower, the Administrative Agent, the Syndication Agent,
the Documentation Agent, the Issuing Bank, the Collateral Agent and the Lenders
may treat each person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Issuing Bank, the Collateral Agent and any
Lender, at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of the Borrower, the Swingline
Lender, the Issuing Bank and the Administrative Agent to such assignment, the
Administrative Agent shall (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register and (iii) give prompt
notice thereof to the Lenders, the Issuing Bank and the Swingline
<PAGE>   82
                                                                              77

Lender. No assignment shall be effective unless and until it has been recorded
in the Register as provided in this paragraph (e).

         (f) Each Lender may without the consent of the Borrower, the Swingline
Lender, the Issuing Bank or the Administrative Agent sell participations to one
or more banks or other entities in all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment
and the Loans owing to it); provided, however, that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the participating banks or other entities shall be
entitled to the benefit of the cost protection provisions contained in Sections
2.14, 2.16 and 2.20 to the same extent as if they were Lenders and (iv) the
Borrower, the Administrative Agent, the Syndication Agent, the Documentation
Agent, the Issuing Bank and the Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of the Borrower relating to the Loans or L/C
Disbursements and to approve any amendment, modification or waiver of any
provision of this Agreement (other than amendments, modifications or waivers
decreasing any fees payable hereunder or the amount of principal of or the rate
at which interest is payable on the Loans, extending any scheduled principal
payment date or date fixed for the payment of interest on the Loans or
increasing or extending the Commitments).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure of
information designated by the Borrower as confidential, each such assignee or
participant or proposed assignee or participant shall execute an agreement
whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of such confidential information on
terms no less restrictive than those applicable to the Lenders pursuant to
Section 9.17.

         (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank to secure extensions of credit by
such Federal Reserve Bank to such Lender; provided that no such assignment shall
release a Lender from any of its obligations hereunder or substitute any such
third party for such Lender as a party hereto. In order to facilitate such an
assignment, the Borrower shall, at the request of the assigning Lender, duly
execute and deliver to the assigning Lender a promissory note or notes
evidencing the Loans made to the Borrower by the assigning Lender hereunder.

         (i) Neither Allied nor the Borrower shall assign or delegate any of its
rights or duties hereunder without the prior written consent of the
Administrative Agent, the Issuing Bank and each Lender, and any attempted
assignment without such consent shall be null and void.

         SECTION 9.05. Expenses; Indemnity. (a) The Borrower and Allied agree,
jointly and severally, to pay all out-of-pocket expenses incurred by the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, the Issuing Bank and the Swingline Lender in connection with
the syndication of the credit facilities provided for herein and the preparation
and administration of this Agreement and the other Loan Documents or in
connection with any amendments, modifications or waivers of the provisions
hereof or thereof (whether or not the transactions hereby or thereby
contemplated shall be consummated) or incurred by the Administrative
<PAGE>   83
                                                                              78

Agent, the Syndication Agent, the Documentation Agent, the Collateral Agent or
any Lender in connection with the enforcement or protection of its rights in
connection with this Agreement and the other Loan Documents or in connection
with the Loans made or Letters of Credit issued hereunder, including the fees,
charges and disbursements of Cravath, Swaine & Moore for the Administrative
Agent, the Syndication Agent, the Documentation Agent and the Collateral Agent,
and, in connection with any such enforcement or protection, the fees, charges
and disbursements of any other counsel for the Administrative Agent, the
Syndication Agent, the Documentation Agent, the Collateral Agent or any Lender.

         (b) The Borrower and Allied agree, jointly and severally, to indemnify
the Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, each Lender and the Issuing Bank, each Affiliate of any of the
foregoing persons and each of their respective directors, officers, employees,
trustees and agents (each such person being called an "Indemnitee") against, and
to hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including reasonable counsel fees, charges and
disbursements, incurred by or asserted against any Indemnitee arising out of, in
any way connected with, or as a result of (i) the execution or delivery of this
Agreement or any other Loan Document or any agreement or instrument contemplated
thereby, the performance by the parties thereto of their respective obligations
thereunder or the consummation of the Transactions and the other transactions
contemplated thereby (whether or not the Transactions are consummated), (ii) the
use of the proceeds of the Loans or issuance of Letters of Credit, (iii) any
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, or (iv) any actual or alleged
presence or Release or threatened Release of Hazardous Materials on any Property
or any property owned, leased or operated by any predecessor of Allied, the
Borrower or the Subsidiaries, or any Environmental Claim related in any way to
Allied, the Borrower or the Subsidiaries; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

         (c) The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the expiration of the Commitments, the expiration
of any Letter of Credit, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Administrative Agent, the Syndication Agent, the
Documentation Agent, the Collateral Agent, any Lender or the Issuing Bank. All
amounts due under this Section 9.05 shall be payable on written demand therefor.

         SECTION 9.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, except to the extent prohibited by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower or Allied against any of and all
the obligations of the Borrower or Allied now or hereafter existing under this
Agreement and other Loan Documents held by such Lender, irrespective of whether
or not such Lender shall have made any demand under this Agreement or such other
Loan Document and although such obligations may be unmatured. The rights of each
Lender under this Section 9.06 are in addition to other rights and remedies
(including other rights of setoff) which such Lender may have.

                                                                              79

         SECTION 9.07. APPLICABLE LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN
DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF
CREDIT, OR IF NO SUCH LAWS OR RULES ARE DESIGNATED, THE UNIFORM CUSTOMS AND
PRACTICE FOR DOCUMENTARY CREDITS (1993 REVISION), INTERNATIONAL CHAMBER OF
COMMERCE, PUBLICATION NO. 500 (THE "UNIFORM CUSTOMS") AND, AS TO MATTERS NOT
GOVERNED BY THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, any Lender or the Issuing Bank in exercising any power or
right hereunder or under any other Loan Document shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent, the
Syndication Agent, the Documentation Agent, the Collateral Agent, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of this Agreement or any other Loan Document or
consent to any departure by the Borrower or any other Loan Party therefrom shall
in any event be effective unless the same shall be permitted by paragraph (b)
below, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. No notice or demand on the
Borrower or Allied in any case shall entitle the Borrower or Allied to any other
or further notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower, Allied and the Required Lenders; provided,
however, that no such agreement shall (i) decrease the principal amount of, or
extend the maturity of or any scheduled principal payment date or extend the
date of any mandatory prepayment of principal, or date for the payment of any
interest on any Loan or any date for reimbursement of an L/C Disbursement, or
waive or excuse any such payment or any part thereof, or decrease the rate of
interest on any Loan or L/C Disbursement, without the prior written consent of
each Lender directly affected thereby, (ii) change or extend the Commitment or
decrease or extend the date for payment of the Commitment Fees or L/C
Participation Fees of any Lender without the prior written consent of such
Lender, (iii) decrease the amount or extend the date for payment of the Issuing
Bank Fees without the prior written consent of each affected Issuing Bank or
(iv) amend or modify the provisions of Section 2.13, 2.17 or 9.04(i), the
provisions of this Section, the definition of the term "Required Lenders" or
release any Guarantor or all or any substantial part of the Collateral, without
the prior written consent of each Lender; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent, the Syndication Agent, the Documentation Agent, the
Collateral Agent, the Issuing Bank or the Swingline Lender hereunder or under
any other Loan Document without the prior written consent of the Administrative
Agent, the Syndication Agent, the Documentation Agent, the Collateral Agent, the
Issuing Bank or the Swingline Lender, respectively.

                                                                              80

         (c) Notwithstanding anything to the contrary, upon delivery of any
Amendment Certificate, each Lender hereby authorizes the Administrative Agent to
enter into on its behalf an amendment to this Agreement that (i) increases the
Bank Facility Amount to the applicable amount set forth in such Amendment
Certificate and (ii) decreases the Additional Facility Amount by the amount that
the Bank Facility Amount is increased in accordance with subclause (i) above. In
the event that the Bank Facility Amount is increased to $400,000,000 and the
Additional Facility Amount is decreased to zero as a result of any amendment
pursuant to this Section 9.08(c), such amendment shall also delete (i) Section
3.10(c) in its entirety and (ii) the last sentence of Section 6.01 in its
entirety.

         SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein
to the contrary, if at any time the interest rate applicable to any Loan or
participation in any L/C Disbursement, together with all fees, charges and other
amounts which are treated as interest on such Loan or participation in such L/C
Disbursement under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan or participation in
accordance with applicable law, the rate of interest payable in respect of such
Loan or participation hereunder, together with all Charges payable in respect
thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Loan or
participation but were not payable as a result of the operation of this Section
9.09 shall be cumulated and the interest and Charges payable to such Lender in
respect of other Loans or participations or periods shall be increased (but not
above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment,
shall have been received by such Lender.

         SECTION 9.10. Entire Agreement. This Agreement, the Fee Letter and the
other Loan Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any other previous agreement among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the other Loan Documents. Nothing in this Agreement or in the other Loan
Documents, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement or the other Loan Documents.

         SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

         SECTION 9.12. Severability. In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and
<PAGE>   86
                                                                              81

therein shall not in any way be affected or impaired thereby (it being
understood that the invalidity of a particular provision in a particular
jurisdiction shall not in and of itself affect the validity of such provision in
any other jurisdiction). The parties shall endeavor in good-faith negotiations
to replace the invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to that of
the invalid, illegal or unenforceable provisions.

         SECTION 9.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

         SECTION 9.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) Each of
Allied and the Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any New York State
court or Federal court of the United States of America sitting in New York City,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent, the Collateral Agent, the Issuing Bank or
any Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against the Borrower, Allied or their
respective properties in the courts of any jurisdiction.

         (b) Each of Allied and the Borrower hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
the other Loan Documents in any New York State or Federal court. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by

      4.7 WELFARE BENEFIT PLAN. Until the Date of Termination, the Executive
and/or the Executive's family, as the case may be, shall be eligible to
participate in and shall receive all benefits under each welfare benefit plan of
the Company currently maintained or hereinafter established by the Company for
the benefit of its employees. Such welfare benefit plans may include, without
limitation, medical, dental, disability, group life, accidental death and travel
accident insurance plans and programs.

<PAGE>   9
      6.2 DEATH OR DISABILITY. (a) Subject to the provisions of this Section
6.2, if this Agreement is terminated as a result of the Executive's Death or
Disability, the Company shall pay to the Executive or his estate, in a lump sum

portion of the Executive's Base Salary (as in effect on the Date of Termination)
owing in respect of the balance of the Employment Period pursuant to Section 3
hereof or (ii) the Executive's Base Salary (as in effect on the Date of
Termination). The Company may purchase insurance to cover all or any part of the
obligation contemplated in the foregoing sentence, and the Executive agrees to
submit to a physical examination to facilitate the procurement of such

uninsurable, such Death or Disability benefit referred to in the first sentence
of this Section 6.2 shall not be provided, and the Executive shall be entitled
to receive only those Death and Disability benefits to which the Executive is
entitled under the Company's benefit plans.

      (b) Whenever compensation is payable to the Executive hereunder during a
period in which he is partially or totally disabled, and such Disability would
(except for the provisions hereof) entitle the Executive to Disability income or
salary continuation payments from the Company according to the terms of any plan
or program presently maintained or hereafter established by the Company, the
Disability income or salary continuation paid to the Executive pursuant to any
such plan or program shall be considered a portion of the payment to be made to
the Executive pursuant to this Section 6.2 and shall not be in addition hereto.
If Disability income is payable directly to the Executive by an insurance
company under tile terms of an insurance policy paid for by the Company, the
amounts paid to the Executive by such insurance company shall be considered a
portion of the payment to be made to the Executive pursuant to this Section 6.2
and shall not be in addition hereto.

      6.3   GOOD REASON; WITHOUT CAUSE.   If this Agreement shall be
terminated either by the Executive for Good Reason or by the Company Without
Cause:

      (a) the Company shall pay to the Executive, in a lump sum in cash within

            (1) if not theretofore paid, the Executive's Base Salary (as in
      effect

            (2) in an amount equal to the largest Annual Bonus paid to the
      Executive out of the last three fiscal years preceding the Date of
      Termination; and

            (3) in the case of compensation previously deferred by the
      Executive, all amounts of such compensation previously deferred and not
      yet paid by the Company;

      (b) the Company shall, promptly upon submission by the Executive of
supporting, documentation, pay or reimburse to the Executive any costs and
expenses (including, moving and relocation expenses) paid or incurred by the
Executive which would have been payable under Section 4.8 of this Agreement if
the Executive's employment had not terminated; and

      (c) until the expiration of the Employment Period or any renewal period
pursuant to Section 3 hereof or of the 12 month period commencing on the Date of
Termination, whichever is longer, the Company shall continue benefits to the
Executive and/or the Executive's family at least equal to those which would have
been provided to them under Section 4.7 if the Executive's employment had not
been terminated; provided that if subsequent to the Date of Termination the
Executive becomes an employee, consultant, agent, officer or director of any
person or business entity that competes with, directly or indirectly, the
Company, then the obligations of the Company under this subparagraph will
terminate in all respects as of the date such relationship commences; and

      (d) the Company shall pay to the Executive, in equal semi-monthly
installments the greater of (i) that portion of the Executive's Base Salary (as
in effect on the Date of Termination) owing, in respect of the balance of the
Employment Period pursuant to Section 3 hereof or (ii) the Executive's Base
Salary (as in effect on the Date of Termination); provided that if subsequent to
the Date of Termination the Executive becomes an employee, consultant, agent,
officer or director of any person or business entity that competes with,
directly or indirectly, the Company then the obligations of the Company under
this subparagraph will terminate in all respects as of the date such
relationship commences.

      6.4 CHANGE IN CONTROL. If (a) this Agreement shall be terminated either by
the Executive for Good Reason or by the Company Without Cause and (b) a Change
in Control of the Company has occurred within the two-year period preceding, the
Date of Termination, then, in addition to the obligations of the Company set
forth in Section 6.3 hereof, the Company shall pay to the Executive, in a lump
sum in cash within 30 days after the Date of Termination, two times the sum of
(x) the Executive's Base Salary (as in effect on the Date of Termination or such
higher rate as may have been in effect at any time during the 90-day period
preceding the Date of Termination) and (y) the Annual Bonus paid to the
Executive for the last full fiscal year. The rights given to the Executive
herein do not apply to the Change of Control of the Company which occurred when
Apollo Advisors, L.P. and The Blackstone Group acquired the Common Stock of
Laidlaw Transportation, Inc.


7.    EXECUTIVE'S OBLIGATION TO AVOID CONFLICTS OF
      INTEREST.

      7.1 In keeping with the Executive's fiduciary duties to the Company, the
Executive agrees that he shall not knowingly become involved in a conflict of
interest with the Company, or upon discovery thereof, allow such a conflict to
continue. The Executive further agrees to disclose to the Company, promptly
after discovery, any facts or circumstances which might involve a conflict of
interest with the Company.

      7.2 The Company and the Executive recognize that it is impossible to
provide an exhaustive list of actions or interests which constitute a "conflict
of interest". Moreover, the Company and the Executive recognize that there are
many borderline situations. In some instances, full disclosure of facts by the
Executive to the Company is all that is necessary to enable the Company to
protect its interests. In others, if no improper motivation appears to exist and
the Company's interests have not suffered, prompt elimination of the outside
interest will suffice. In still others, it may be necessary for the Company to
terminate the employment relationship. The Company and the Executive agree that
the Company's determination as to whether or not a conflict of interest exists
shall be conclusive. The Company reserves the right to take such action as, in
its judgment, will end the conflict of interest.


                                       11
<PAGE>   12
      7.3 In this connection, it is agreed that any direct or indirect interest
in, connection with or benefit from any outside activities, particularly
commercial activities, which interest might in any way adversely affect the
Company or its Affiliates, involves a possible conflict of interest.
Circumstances in which a conflict of interest on the part of the Executive would
or might arise, and which should be reported immediately to the Company,
include, but are not limited to, the following:

      (a) Ownership of a material interest in any lender, supplier, contractor,
subcontractor, customer or other entity with which the Company does business.

      (b) Acting in any capacity, including director, officer, partner,
consultant, employee, distributor, agent or the like, for any lender, supplier,
contractor, subcontractor, customer or other entity with which the Company does
business.

      (c) Acceptance, directly or indirectly, of payments, services or loans
from a lender, supplier, contractor, subcontractor, customer or other entity
with which the Company does business, including, without limitation, gifts,
trips, entertainment or other favors of more than a nominal value, but
excluding, loans from publicly held insurance companies and commercial or
savings banks at market rates of interest.

      (d) Use of information or facilities to which the Executive has access in
a manner which will be detrimental to the Company's interests, such as use for
the Executive's own benefit of know-how or information developed through the
Company's business activities.

      (e) Disclosure or other misuse of information of any kind obtained through
the Executive's connection with the Company.

      (f) Acquiring or trading in, directly or indirectly, other properties or
interests connected with the design or marketing of products or services
designed or marketed by the Company.

Affiliates, or from all the relevant circumstances should reasonably be assumed
by the Executive to be confidential and proprietary to the Company or its
Affiliates, or (iv) is not generally known by non-Company personnel. Such
Confidential Information includes, without limitation, the following types of
information and other information of a similar nature (whether or not reduced to

<PAGE>   14
its Affiliates by any actual or potential customer, government agency or other
third party (including businesses, consultants and other entities and
individuals).

      8.3 As a consequence of the Executive's acquisition or anticipated
acquisition of Confidential Information, the Executive shall occupy a position
of trust and confidence with respect to the affairs and business of the Company
and its Affiliates. In view of the foregoing, and of the consideration to be
provided to the Executive, the Executive agrees that it is reasonable and
necessary that the Executive make each of the following covenants:

      (a) At any time during the Employment Period and thereafter, the Executive
shall not disclose Confidential Information to any person or entity, either
inside or outside of the Company, other than as necessary in carrying out his
duties and responsibilities as set forth in Section 2 hereof, without first
obtaining the Company's prior written consent (unless such disclosure is
compelled pursuant to court orders or subpoena, and at which time the Executive
shall give notice of such proceedings to the Company).

      (b) At any time during the Employment Period and thereafter, the Executive
shall not use, copy or transfer Confidential Information other than as necessary
in carrying out his duties and responsibilities as set forth in Section 2
hereof, without first obtaining the Company's prior written consent.

the Company (or its designee) all written materials, records and documents made
by the Executive or which came into his possession prior to or during the
Employment Period concerning, the business or affairs of the Company or its
Affiliates, including, without limitation, all materials containing Confidential
Information.

9.    DISCLOSURE OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS.

As part of the Executive's fiduciary duties to the Company, the Executive agrees
that during his employment by the Company and for a period of three years
following the Date of Termination, the Executive shall promptly disclose in
writing, to the Company all information, ideas, concepts, improvements,
discoveries and inventions, whether patentable or not, and whether or not
reduced


                                       14
<PAGE>   15
to practice, which are conceived, developed, made or acquired by the Executive,
either individually or jointly with others, and which relate to the business,
products or services of the Company or its Affiliates, irrespective of whether
the Executive used the Company's time or facilities and irrespective of whether
such information, idea, concept, improvement, discovery or invention was
conceived, developed, discovered or acquired by the Executive on the job, at
home, or elsewhere. This obligation extends to all types of information, ideas
and concepts, including, information, ideas and concepts relating to new types
of services, corporate opportunities, acquisition prospects, the identity of key
representatives within acquisition prospect organizations, prospective names or
service marks for the Company's business activities, and the like.

10.   OWNERSHIP OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS AND ALL
      ORIGINAL WORKS OF AUTHORSHIP.

      10.1 All information, ideas, concepts, improvements, discoveries and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by the Executive or which are disclosed or made known to the Executive,
individually or in conjunction with others, during the Executive's employment by
the Company and which relate to the business, products or services of the

      10.2 In particular, the Executive hereby specifically sells, assigns,
transfers and conveys to the Company all of his worldwide right, title and
interest in and to all such information, ideas, concepts, improvements,
discoveries or inventions, and any United States or foreign applications for
patents, inventor's certificates or


                                       15
<PAGE>   16
other industrial rights which may be filed in respect thereof, including
divisions, continuations, continuations-in-part, reissues and/or extensions
thereof, and applications for registration of such names and service marks. The
Executive shall assist the Company and its nominee at all times, during the
Employment Period and thereafter, in the protection of such information, ideas,
concepts, improvements, discoveries or inventions, both in the United States and
all foreign countries, which assistance shall include, but shall not be limited

patent, including divisions, continuations, continuations-in-part, reissues
and/or extensions thereof, and any application for the registration of such
names and service marks.

      10.3 In the event the Executive creates, during the Employment Period, any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as, videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures or the like) relating to the Company's business
products or services, whether such work is created solely by the Executive or
jointly with others, the Company) shall be deemed the author of such work if the
work is prepared by the Executive in the scope of his employment; or, if the
work is not prepared by the Executive within the scope of his employment but is
specially ordered by the Company as a contribution to a collective work, as a
part of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation or as an instructional text, then the work
shall be considered to be work made for hire, and the Company shall be the
author of such work. If such work is neither prepared by the Executive within
the scope of his employment nor a work specially ordered and deemed to be a work
made for hire, then the Executive hereby agrees to sell, transfer, assign and
convey, and by these presents, does sell, transfer, assign and convey, to the
Company all of the Executive's worldwide right, title and interest in and to

11.   CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.

Anything in this Agreement to the contrary notwithstanding, in the event it
shall be determined that any payment or distribution by the Company to or for
the benefit of the Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise) (a
"Payment") would be nondeductible by the Company for federal income tax purposes
because of Section 28OG of the Code, then the aggregate present value of amounts
payable or distributable to or for the benefit of the Executive pursuant to this
Agreement (such payments or distributions pursuant to this Agreement are
hereinafter referred to as "Agreement Payments") shall be reduced (but not below
zero) to the Reduced Amount. The "Reduced Amount" shall be an amount expressed
in present value which maximizes the aggregate present value of Agreement
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. Anything in this Agreement to the contrary
notwithstanding, if the Reduced Amount is zero and it is determined further that
any Payment which is not an Agreement Payment would nevertheless be
nondeductible by the Company for federal income tax purposes because of Section
28OG of the Code. then the aggregate present value of Payments, which are not
Agreement Payments, shall also be reduced (but not below zero) to an amount
expressed in present value which maximizes the aggregate present value of
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. For purposes of this Section 11, present value
shall be determined in accordance with Section 28OG(d)(4) of the Code. All
determinations required to be made under this Section 11 shall be made by the
Company's independent certified public accountant (the "Accounting Firm") which
shall provide detailed supporting calculations both to the Company and the
Executive within 15 business days of the Date of Termination. Any such
determination by the Accounting Firm shall be binding upon the Company and the
Executive. The Executive shall determine which and how much of the Agreement
Payments (or, at the election of the Executive, other Payments) shall be
eliminated or reduced consistent with the requirements of this Section 11
provided, that if the Executive does not make such determination within ten
business days of the receipt of the calculations made by the Accounting Firm,
the Company shall elect which and how much of the Agreement Payments shall be
eliminated or reduced consistent with the requirements of this Section 11 and
shall notify the Executive promptly of such election. Within five business days
thereafter, the Company shall pay to or distribute for the benefit of the
Executive such amounts as are then due to the


                                       17
<PAGE>   18
Executive under this Agreement and shall promptly pay to or distribute for the
benefit of the Executive in the future such amounts as become due to the
Executive under this Agreement. As a result of the uncertainty in the
application of Section 28OG of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Agreement Payments will
have been made by the Company which should not have been made ("Overpayment") or
that additional Agreement Payments which have not been made by the Company could
have been made ("Underpayment"), in each case, consistent with the calculations
required to be made hereunder. In the event that the Accounting Firm determines
that an Overpayment has been made, any such Overpayment shall be treated for all
purposes as a loan to the Executive which the Executive shall repay to the
Company, together with interest at the applicable federal rate provided for in
Section 7872(E)(2) of the Code; provided, however, that no amount shall be
payable by the Executive to the Company if and to the extent such payment would
not reduce the amount which is subject to taxation under Section 4999 of the
Code. In the event that the Accounting Firm determines that an Underpayment has
occurred, any such Underpayment shall be promptly paid by the Company to or for
the benefit of the Executive, together with interest at the applicable federal
rate provided for in Section 7872(f(2) of the Code.

12.   EXECUTIVE'S NON-COMPETITION OBLIGATION.

      12.1 (a) Until the Date of Termination, the Executive shall not, acting
alone or in conjunction with others, directly or indirectly, in any of the
business territories in which the Company or any of its Affiliates is presently
or from time to time during the Employment Period conducting business, invest or
engage, directly or indirectly, in any business which is competitive with that
of the Company or accept employment with or render services to such a competitor
as a director, officer, agent, employee or consultant, or take any action
inconsistent with the fiduciary relationship of an employee to his employer;
provided, however, that the beneficial ownership by the Executive of up to three
percent of the Voting-Stock of any corporation subject to the periodic reporting
requirements of the Exchange Act shall not violate this Section 12.1 (a).

      (b) In addition to the other obligations agreed to by the Executive in
this Agreement, the Executive agrees that until the Date of Termination, he
shall not at any time, directly or indirectly, (i) induce, entice or solicit any
employee of the Company to leave his employment, (ii) contact, communicate or
solicit any


                                       18
<PAGE>   19
customer or acquisition prospect of the Company derived from any customer list,
customer lead, mail, printed matter or other information secured from the
Company or its present or past employees or (iii) in any other manner use any
customer lists or customer leads, mail, telephone numbers, printed material or
other information of the Company relating thereto.

      12.2 (a) If this Agreement is terminated either by the Company for Cause
or by the Executive for any reason other than Good Reason, then for a period of
three years following, the Date of Termination, the Executive shall not, acting
alone or in conjunction with others, directly or indirectly, in any of the
business territories in which the Company or any of its Affiliates is presently
or at the Date of Termination conducting, business, invest or engage, directly
or indirectly, in any business which is competitive with that of the Company as

hereof or (ii) the Executive's Base Salary (as in effect on the Date of
Termination). The Company may purchase insurance to cover all or any part of the
obligation contemplated in the foregoing sentence, and the Executive agrees to
submit to a physical examination to facilitate the procurement of such
insurance. If the physical examination reveals that the Executive is
uninsurable, such death or Disability benefit referred to in the first sentence
of this Section 6.2 shall not be provided, and the Executive shall be entitled
to receive only those death and Disability benefits to which the Executive is
entitled under the Company's benefit plans.

      (b) Whenever compensation is payable to the Executive hereunder during a
period in which he is partially or totally disabled, and such Disability would
(except for the provisions hereof) entitle the Executive to Disability income or
salary continuation payments from the Company according to the terms of any plan
or program presently maintained or hereafter established by the Company, the
Disability income or salary continuation paid to the Executive pursuant to any
such plan or program shall be considered a portion of the payment to be made to
the Executive pursuant to this Section 6.2 and shall not be in addition hereto.
If Disability income is payable directly to the Executive by an insurance
company under tile terms of an insurance policy paid for by the Company, the
amounts paid to the Executive by such insurance company shall be considered a
portion of the payment to be made to the Executive pursuant to this Section 6.2
and shall not be in addition hereto.

      6.3   GOOD REASON; WITHOUT CAUSE.   If this Agreement shall be
terminated either by the Executive for Good Reason or by the Company Without
Cause:

      (a) the Company shall pay to the Executive, in a lump sum in cash within
30 days after the Date of Termination, the aggregate of the following amounts:

            (1) if not theretofore paid, the Executive's Base Salary (as in
      effect


                                        9
<PAGE>   10
      on the Date of Termination) through the Date of Termination;

            (2) in an amount equal to the largest Annual Bonus paid to the
      Executive out of the last three fiscal years preceding the Date of
      Termination; and

            (3) in the case of compensation previously deferred by the
      Executive, all amounts of such compensation previously deferred and not
      yet paid by the Company;

      (b) the Company shall, promptly upon submission by the Executive of
supporting, documentation, pay or reimburse to the Executive any costs and
expenses (including, moving and relocation expenses) paid or incurred by the
Executive which would have been payable under Section 4.8 of this Agreement if
the Executive's employment had not terminated; and

      (c) until the expiration of the Employment Period pursuant to Section 3
hereof or of the 12 month period commencing on the Date of Termination,
whichever is longer, the Company shall continue benefits to the Executive and/or
the Executive's family at least equal to those which would have been provided to
them under Section 4.7 if the Executive's employment had not been terminated;
provided that if subsequent to the Date of Termination the Executive becomes an
employee, consultant, agent, officer or director of any person or business
entity that competes with, directly or indirectly, the Company, then the
obligations of the Company under this subparagraph will terminate in all
respects as of the date such relationship commences; and

      (d) the Company shall pay to the Executive, in equal semi-monthly
installments the greater of (i) that portion of the Executive's Base Salary (as
in effect on the Date of Termination) owing, in respect of the balance of the
Employment Period pursuant to Section 3 hereof or (ii) the Executive's Base
Salary (as in effect on the Date of Termination); provided that if subsequent to
the Date of Termination the Executive becomes an employee, consultant, agent,
officer or director of any person or business entity that competes with,
directly or indirectly, the Company then the obligations of the Company under
this subparagraph will terminate in all respects as of the date such
relationship commences.

      6.4 CHANGE IN CONTROL. If (a) this Agreement shall be terminated either by
the Executive for Good Reason or by the Company Without Cause and (b) a Change
in Control of the Company has occurred within the two-year period preceding, the
Date of Termination, then, in addition to the obligations of the Company set
forth in Section 6.3 hereof, the Company shall pay to the Executive, in a lump
sum in cash within 30 days after the Date of Termination, two times the sum of
(x) the Executive's Base Salary (as in effect on the Date of Termination or such
higher rate as may have been in effect at any time during the 90-day period
preceding the Date of Termination) and (y) the Annual Bonus paid to the
Executive for the last full fiscal year. The rights given to the Executive
herein do not apply to the Change of Control of the Company which occurred when
Apollo Advisors, L.P. and The Blackstone Group acquired the Common Stock of
Laidlaw Transportation, Inc.


7.    EXECUTIVE'S OBLIGATION TO AVOID CONFLICTS OF
      INTEREST.

      7.1 In keeping with the Executive's fiduciary duties to the Company, the
Executive agrees that he shall not knowingly become involved in a conflict of
interest with the Company, or upon discovery thereof, allow such a conflict to
continue. The Executive further agrees to disclose to the Company, promptly
after discovery, any facts or circumstances which might involve a conflict of
interest with the Company.

      7.2 The Company and the Executive recognize that it is impossible to
provide an exhaustive list of actions or interests which constitute a "conflict
of interest". Moreover, the Company and the Executive recognize that there are
many borderline situations. In some instances, full disclosure of facts by the
Executive to the Company is all that is necessary to enable the Company to
protect its interests. In others, if no improper motivation appears to exist and
the Company's interests have not suffered, prompt elimination of the outside
interest will suffice. In still others, it may be necessary for the Company to
terminate the employment relationship. The Company and the Executive agree that
the Company's determination as to whether or not a conflict of interest exists
shall be conclusive. The Company reserves the right to take such action as, in
its judgment, will end the conflict of interest.


                                       11
<PAGE>   12
      7.3 In this connection, it is agreed that any direct or indirect interest
in, connection with or benefit from any outside activities, particularly
commercial activities, which interest might in any way adversely affect the
Company or its Affiliates, involves a possible conflict of interest.
Circumstances in which a conflict of interest on the part of the Executive would
or might arise, and which should be reported immediately to the Company,
include, but are not limited to, the following:

      (a) Ownership of a material interest in any lender, supplier, contractor,
subcontractor, customer or other entity with which the Company does business.

      (b) Acting in any capacity, including director, officer, partner,
consultant, employee, distributor, agent or the like, for any lender, supplier,
contractor, subcontractor, customer or other entity with which the Company does
business.

      (c) Acceptance, directly or indirectly, of payments, services or loans
from a lender, supplier, contractor, subcontractor, customer or other entity
with which the Company does business, including, without limitation, gifts,
trips, entertainment or other favors of more than a nominal value, but
excluding, loans from publicly held insurance companies and commercial or
savings banks at market rates of interest.

      (d) Use of information or facilities to which the Executive has access in
a manner which will be detrimental to the Company's interests, such as use for
the Executive's own benefit of know-how or information developed through the
Company's business activities.

      (e) Disclosure or other misuse of information of any kind obtained through
the Executive's connection with the Company.

      (f) Acquiring or trading in, directly or indirectly, other properties or
interests connected with the design or marketing of products or services
designed or marketed by the Company.

as such in accordance with this Section 8. The Executive acknowledges that all
such Confidential Information is in the nature of a trade secret.

opportunity of obtaining such advantage or the disclosure of which could be
detrimental to the interests of the Company or its Affiliates, (iii) is
designated as Confidential Information by the Company or its Affiliates, is
known by the Executive to be considered confidential by the Company or its
Affiliates, or from all the relevant circumstances should reasonably be assumed
by the Executive to be confidential and proprietary to the Company or its
Affiliates, or (iv) is not generally known by non-Company personnel. Such
Confidential Information includes, without limitation, the following types of
information and other information of a similar nature (whether or not reduced to

<PAGE>   14
its Affiliates by any actual or potential customer, government agency or other
third party (including businesses, consultants and other entities and
individuals).

      8.3 As a consequence of the Executive's acquisition or anticipated
acquisition of Confidential Information, the Executive shall occupy a position
of trust and confidence with respect to the affairs and business of the Company
and its Affiliates. In view of the foregoing, and of the consideration to be
provided to the Executive, the Executive agrees that it is reasonable and
necessary that the Executive make each of the following covenants:

      (a) At any time during the Employment Period and thereafter, the Executive
shall not disclose Confidential Information to any person or entity, either
inside or outside of the Company, other than as necessary in carrying out his
duties and responsibilities as set forth in Section 2 hereof, without first
obtaining the Company's prior written consent (unless such disclosure is
compelled pursuant to court orders or subpoena, and at which time the Executive
shall give notice of such proceedings to the Company).

      (b) At any time during the Employment Period and thereafter, the Executive
shall not use, copy or transfer Confidential Information other than as necessary
in carrying out his duties and responsibilities as set forth in Section 2
hereof, without first obtaining the Company's prior written consent.

      (c) On the Date of Termination, the Executive shall promptly deliver to
the Company (or its designee) all written materials, records and documents made
by the Executive or which came into his possession prior to or during the
Employment Period concerning, the business or affairs of the Company or its
Affiliates, including, without limitation, all materials containing Confidential
Information.

9.    DISCLOSURE OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS.

As part of the Executive's fiduciary duties to the Company, the Executive agrees
that during his employment by the Company and for a period of three years
following the Date of Termination, the Executive shall promptly disclose in
writing, to the Company all information, ideas, concepts, improvements,
discoveries and inventions, whether patentable or not, and whether or not
reduced


                                       14
<PAGE>   15
to practice, which are conceived, developed, made or acquired by the Executive,
either individually or jointly with others, and which relate to the business,
products or services of the Company or its Affiliates, irrespective of whether
the Executive used the Company's time or facilities and irrespective of whether
such information, idea, concept, improvement, discovery or invention was
conceived, developed, discovered or acquired by the Executive on the job, at
home, or elsewhere. This obligation extends to all types of information, ideas
and concepts, including, information, ideas and concepts relating to new types
of services, corporate opportunities, acquisition prospects, the identity of key
representatives within acquisition prospect organizations, prospective names or
service marks for the Company's business activities, and the like.

10.   OWNERSHIP OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS AND ALL
      ORIGINAL WORKS OF AUTHORSHIP.

      10.1 All information, ideas, concepts, improvements, discoveries and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by the Executive or which are disclosed or made known to the Executive,
individually or in conjunction with others, during the Executive's employment by
the Company and which relate to the business, products or services of the
Company or its Affiliates (including, without limitation, all such information

and trading terms, evaluations, opinions, interpretations, acquisition
prospects, the identity of customers or their requirements, the identity of key

other writings or materials of any type embodying, any of such information,
ideas, concepts, improvements, discoveries and inventions are and shall be the

      10.2 In particular, the Executive hereby specifically sells, assigns,
transfers and conveys to the Company all of his worldwide right, title and
interest in and to all such information, ideas, concepts, improvements,
discoveries or inventions, and any United States or foreign applications for
patents, inventor's certificates or


                                       15
<PAGE>   16
other industrial rights which may be filed in respect thereof, including
divisions, continuations, continuations-in-part, reissues and/or extensions
thereof, and applications for registration of such names and service marks. The
Executive shall assist the Company and its nominee at all times, during the
Employment Period and thereafter, in the protection of such information, ideas,
concepts, improvements, discoveries or inventions, both in the United States and
all foreign countries, which assistance shall include, but shall not be limited

patent, including divisions, continuations, continuations-in-part, reissues
and/or extensions thereof, and any application for the registration of such
names and service marks.

      10.3 In the event the Executive creates, during the Employment Period, any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as, videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures or the like) relating to the Company's business
products or services, whether such work is created solely by the Executive or
jointly with others, the Company) shall be deemed the author of such work if the
work is prepared by the Executive in the scope of his employment; or, if the
work is not prepared by the Executive within the scope of his employment but is
specially ordered by the Company as a contribution to a collective work, as a
part of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation or as an instructional text, then the work
shall be considered to be work made for hire, and the Company shall be the
author of such work. If such work is neither prepared by the Executive within
the scope of his employment nor a work specially ordered and deemed to be a work
made for hire, then the Executive hereby agrees to sell, transfer, assign and
convey, and by these presents, does sell, transfer, assign and convey, to the
Company all of the Executive's worldwide right, title and interest in and to
such work and all rights of copyright therein. The Executive agrees to assist

11.   CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.

Anything in this Agreement to the contrary notwithstanding, in the event it
shall be determined that any payment or distribution by the Company to or for
the benefit of the Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise) (a
"Payment") would be nondeductible by the Company for federal income tax purposes
because of Section 28OG of the Code, then the aggregate present value of amounts
payable or distributable to or for the benefit of the Executive pursuant to this
Agreement (such payments or distributions pursuant to this Agreement are
hereinafter referred to as "Agreement Payments") shall be reduced (but not below
zero) to the Reduced Amount. The "Reduced Amount" shall be an amount expressed
in present value which maximizes the aggregate present value of Agreement
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. Anything in this Agreement to the contrary
notwithstanding, if the Reduced Amount is zero and it is determined further that
any Payment which is not an Agreement Payment would nevertheless be
nondeductible by the Company for federal income tax purposes because of Section
28OG of the Code. then the aggregate present value of Payments, which are not
Agreement Payments, shall also be reduced (but not below zero) to an amount
expressed in present value which maximizes the aggregate present value of
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. For purposes of this Section 11, present value
shall be determined in accordance with Section 28OG(d)(4) of the Code. All
determinations required to be made under this Section 11 shall be made by the
Company's independent certified public accountant (the "Accounting Firm") which
shall provide detailed supporting calculations both to the Company and the
Executive within 15 business days of the Date of Termination. Any such
determination by the Accounting Firm shall be binding upon the Company and the
Executive. The Executive shall determine which and how much of the Agreement
Payments (or, at the election of the Executive, other Payments) shall be
eliminated or reduced consistent with the requirements of this Section 11
provided, that if the Executive does not make such determination within ten
business days of the receipt of the calculations made by the Accounting Firm,
the Company shall elect which and how much of the Agreement Payments shall be
eliminated or reduced consistent with the requirements of this Section 11 and
shall notify the Executive promptly of such election. Within five business days
thereafter, the Company shall pay to or distribute for the benefit of the
Executive such amounts as are then due to the


                                       17
<PAGE>   18
Executive under this Agreement and shall promptly pay to or distribute for the
benefit of the Executive in the future such amounts as become due to the
Executive under this Agreement. As a result of the uncertainty in the
application of Section 28OG of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Agreement Payments will
have been made by the Company which should not have been made ("Overpayment") or
that additional Agreement Payments which have not been made by the Company could
have been made ("Underpayment"), in each case, consistent with the calculations
required to be made hereunder. In the event that the Accounting Firm determines
that an Overpayment has been made, any such Overpayment shall be treated for all
purposes as a loan to the Executive which the Executive shall repay to the
Company, together with interest at the applicable federal rate provided for in
Section 7872(E)(2) of the Code; provided, however, that no amount shall be
payable by the Executive to the Company if and to the extent such payment would
not reduce the amount which is subject to taxation under Section 4999 of the
Code. In the event that the Accounting Firm determines that an Underpayment has
occurred, any such Underpayment shall be promptly paid by the Company to or for
the benefit of the Executive, together with interest at the applicable federal
rate provided for in Section 7872(f(2) of the Code.

12.   EXECUTIVE'S NON-COMPETITION OBLIGATION.

      12.1 (a) Until the Date of Termination, the Executive shall not, acting
alone or in conjunction with others, directly or indirectly, in any of the

engage, directly or indirectly, in any business which is competitive with that
of the Company or accept employment with or render services to such a competitor
as a director, officer, agent, employee or consultant, or take any action
inconsistent with the fiduciary relationship of an employee to his employer;

action inconsistent with the fiduciary relationship of an employee to his
employer; provided, however, that the beneficial ownership by the Executive of

periodic reporting requirements of the Exchange Act shall not violate this
Section 12.2(a).

      (b) In addition to the other obligations agreed to by the Executive in
this Agreement, the Executive agrees that if this Agreement is terminated either
by the Company for Cause or by the Executive for any reason other than Good
Reason, then for a period of three years following, the Date of Termination, he
shall not at any time, directly or indirectly, (i) induce, entice or solicit any

solicit any customer or acquisition prospect of the Company derived from any
customer list, customer lead, mail, printed matter or other information secured
from the Company or its present or past employees or (iii) in any other manner
use any customer lists or customer leads, mail, telephone numbers, printed
material or other information of the Company relating thereto.

      12.3 (a) If this Agreement is terminated either by the Executive for Good
Reason or by the Company Without Cause, provided that no Change in Control of
the Company has occurred during the two-year period preceding the Date of
Termination, then during the balance of the Employment Period or the 12-month
period commencing on the Date of Termination, whichever is longer, the Executive
shall not, acting alone or in conjunction with others, directly or


                                       19
<PAGE>   20

its Affiliates is presently or at the Date of Termination conducting business,
invest or engage, directly or indirectly, in any business which is competitive
with that of the Company as of the Date of Termination or accept employment with
or render services to such a competitor as a director, officer, agent, employee
or consultant, or take any action inconsistent with the fiduciary relationship
of an employee to his employer; provided, however, that the beneficial ownership
by the Executive of up to three percent of the Voting Stock of any corporation
subject to the periodic reporting, requirements of the Exchange Act shall not
violate this Section 12.3(a).

      (b) In addition to the other obligations agreed to by the Executive in
this Agreement, the Executive agrees that if this Agreement is terminated either
by Executive for Good Reason or by the Company Without Cause, provided that no
Change in Control of the Company has occurred during the two year period
preceding the Date of Termination then during the balance of the Employment
Period or the 12-month period commencing on the Date of Termination, whichever
is longer, he shall not at any time, directly or indirectly (i) induce. entice
or solicit any employee of the Company to leave his employment, (ii) contact,
communicate or solicit any customer or acquisition prospect of the Company
derived from any customer list, customer lead, mail, printed matter or other
information secured from the Company or its present or past employees or (iii)
in any other manner use any customer lists or customer leads, mail, telephone
numbers, printed material or other information of the Company relating thereto.

      12.4 If this Agreement is terminated (a) either by the Executive for Good
Reason or by the Company Without Cause and (b) a Chance in Control of the
Company has occurred during the two-year period preceding the Date of
Termination, or if this Agreement is terminated as a result of the Executive's

provided that if subsequent to the Date of Termination the Executive becomes an
employee, consultant, agent, officer or director of any person or business
entity that competes with, directly or indirectly, the Company, then the
obligations of the Company under this subparagraph will terminate in all
respects as of the date such relationship commences; and

      (d) the Company shall pay to the Executive, in equal semi-monthly
installments the greater of (i) that portion of the Executive's Base Salary (as
in effect on the Date of Termination) owing, in respect of the balance of the

7.    EXECUTIVE'S OBLIGATION TO AVOID CONFLICTS OF INTEREST.

      7.1 In keeping with the Executive's fiduciary duties to the Company, the
Executive agrees that he shall not knowingly become involved in a conflict of
interest with the Company, or upon discovery thereof, allow such a conflict to
continue. The Executive further agrees to disclose to the Company, promptly
after discovery, any facts or circumstances which might involve a conflict of
interest with the Company.

      7.2 The Company and the Executive recognize that it is impossible to
provide an exhaustive list of actions or interests which constitute a "conflict
of interest". Moreover, the Company and the Executive recognize that there are
many borderline situations. In some instances, full disclosure of facts by the
Executive to the Company is all that is necessary to enable the Company to
protect


                                       11
<PAGE>   12
its interests. In others, if no improper motivation appears to exist and the
Company's interests have not suffered, prompt elimination of the outside
interest will suffice. In still others, it may be necessary for the Company to
terminate the employment relationship. The Company and the Executive agree that
the Company's determination as to whether or not a conflict of interest exists
shall be conclusive. The Company reserves the right to take such action as, in
its judgment, will end the conflict of interest.

      7.3 In this connection, it is agreed that any direct or indirect interest
in, connection with or benefit from any outside activities, particularly
commercial activities, which interest might in any way adversely affect the
Company or its Affiliates, involves a possible conflict of interest.
Circumstances in which a conflict of interest on the part of the Executive would
or might arise, and which should be reported immediately to the Company,
include, but are not limited to, the following:

      (a) Ownership of a material interest in any lender, supplier, contractor,
subcontractor, customer or other entity with which the Company does business.

      (b) Acting in any capacity, including director, officer, partner,
consultant, employee, distributor, agent or the like, for any lender, supplier,
contractor, subcontractor, customer or other entity with which the Company does
business.

      (c) Acceptance, directly or indirectly, of payments, services or loans
from a lender, supplier, contractor, subcontractor, customer or other entity
with which the Company does business, including, without limitation, gifts,
trips, entertainment or other favors of more than a nominal value, but
excluding, loans from publicly held insurance companies and commercial or
savings banks at market rates of interest.

      (d) Use of information or facilities to which the Executive has access in
a manner which will be detrimental to the Company's interests, such as use for
the Executive's own benefit of know-how or information developed through the
Company's business activities.

      (e) Disclosure or other misuse of information of any kind obtained through
the Executive's connection with the Company.


                                       12
<PAGE>   13
      (f) Acquiring or trading in, directly or indirectly, other properties or
interests connected with the design or marketing of products or services
designed or marketed by the Company.

9.    DISCLOSURE OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS.

As part of the Executive's fiduciary duties to the Company, the Executive agrees
that during his employment by the Company and for a period of three years
following the Date of Termination, the Executive shall promptly disclose in
writing, to the Company all information, ideas, concepts, improvements,
discoveries and inventions, whether patentable or not, and whether or not
reduced to practice, which are conceived, developed, made or acquired by the
Executive, either individually or jointly with others, and which relate to the
business, products or services of the Company or its Affiliates, irrespective of
whether the Executive used the Company's time or facilities and irrespective of
whether such information, idea, concept, improvement, discovery or invention was
conceived, developed, discovered or acquired by the Executive on the job, at
home, or elsewhere. This obligation extends to all types of information, ideas
and concepts, including, information, ideas and concepts relating to new types
of services, corporate opportunities, acquisition prospects, the identity of key
representatives within acquisition prospect organizations, prospective names or
service marks for the Company's business activities, and the like.


10.   OWNERSHIP OF INFORMATION, IDEAS, CONCEPTS,
      IMPROVEMENTS, DISCOVERIES AND INVENTIONS AND ALL
      ORIGINAL WORKS OF AUTHORSHIP.

      10.1 All information, ideas, concepts, improvements, discoveries and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by the Executive or which are disclosed or made known to the Executive,
individually or in conjunction with others, during the Executive's employment by

correspondence,


                                       15
<PAGE>   16
manuals, models, specifications, computer programs, maps and all other writings
or materials of any type embodying, any of such information, ideas, concepts,
improvements, discoveries and inventions are and shall be the sole and exclusive
property of the Company.

      10.2 In particular, the Executive hereby specifically sells, assigns,
transfers and conveys to the Company all of his worldwide right, title and
interest in and to all such information, ideas, concepts, improvements,
discoveries or inventions, and any United States or foreign applications for
patents, inventor's certificates or other industrial rights which may be filed
in respect thereof, including divisions, continuations, continuations-in-part,
reissues and/or extensions thereof, and applications for registration of such
names and service marks. The Executive shall assist the Company and its nominee

for the registration of such names and service marks.

      10.3 In the event the Executive creates, during the Employment Period, any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as, videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures or the like) relating to the Company's business
products or services, whether such work is created solely by the Executive or
jointly with others, the Company) shall be deemed the author of such work if the
work is prepared by the Executive in the scope of his employment; or, if the
work is not prepared by the Executive within the scope of his employment but is
specially ordered by the Company as a contribution to a collective work, as a
part of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation or as an instructional text, then the work
shall be considered to be work made for hire, and the Company shall be the
author of such work. If such work is neither prepared by the Executive within
the scope of his employment nor a work specially ordered and deemed to be a work
made for hire, then the Executive hereby agrees to sell, transfer, assign and
convey, and by these


                                       16
<PAGE>   17
presents, does sell, transfer, assign and convey, to the Company all of the
Executive's worldwide right, title and interest in and to such work and all
rights of copyright therein. The Executive agrees to assist the Company and its
Affiliates, at all times, during the Employment Period and thereafter, in the
protection of the Company's worldwide right, title and interest in and to such
work and all rights of copyright therein, which assistance shall include, but
shall not be limited to, the execution of all documents requested by the Company
or its nominee and the execution of all lawful oaths and applications for
registration of copyright in the United States and foreign countries.


11.   CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.

Anything in this Agreement to the contrary notwithstanding, in the event it
shall be determined that any payment or distribution by the Company to or for
the benefit of the Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise) (a
"Payment") would be nondeductible by the Company for federal income tax purposes
because of Section 28OG of the Code, then the aggregate present value of amounts
payable or distributable to or for the benefit of the Executive pursuant to this
Agreement (such payments or distributions pursuant to this Agreement are
hereinafter referred to as "Agreement Payments") shall be reduced (but not below
zero) to the Reduced Amount. The "Reduced Amount" shall be an amount expressed
in present value which maximizes the aggregate present value of Agreement
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. Anything in this Agreement to the contrary
notwithstanding, if the Reduced Amount is zero and it is determined further that
any Payment which is not an Agreement Payment would nevertheless be
nondeductible by the Company for federal income tax purposes because of Section
28OG of the Code. then the aggregate present value of Payments, which are not
Agreement Payments, shall also be reduced (but not below zero) to an amount
expressed in present value which maximizes the aggregate present value of
Payments without causing any Payment to be nondeductible by the Company because
of Section 28OG of the Code. For purposes of this Section 11, present value
shall be determined in accordance with Section 28OG(d)(4) of the Code. All
determinations required to be made under this Section 11 shall be made by the
Company's independent certified public accountant (the "Accounting Firm") which
shall provide detailed supporting calculations both to the Company and the
Executive within 15 business


                                       17
<PAGE>   18
days of the Date of Termination. Any such determination by the Accounting Firm
shall be binding upon the Company and the Executive. The Executive shall
determine which and how much of the Agreement Payments (or, at the election of
the Executive, other Payments) shall be eliminated or reduced consistent with
the requirements of this Section 11 provided, that if the Executive does not
make such determination within ten business days of the receipt of the
calculations made by the Accounting Firm, the Company shall elect which and how
much of the Agreement Payments shall be eliminated or reduced consistent with
the requirements of this Section 11 and shall notify the Executive promptly of
such election. Within five business days thereafter, the Company shall pay to or
distribute for the benefit of the Executive such amounts as are then due to the
Executive under this Agreement and shall promptly pay to or distribute for the
benefit of the Executive in the future such amounts as become due to the
Executive under this Agreement. As a result of the uncertainty in the
application of Section 28OG of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Agreement Payments will
have been made by the Company which should not have been made ("Overpayment") or
that additional Agreement Payments which have not been made by the Company could
have been made ("Underpayment"), in each case, consistent with the calculations
required to be made hereunder. In the event that the Accounting Firm determines
that an Overpayment has been made, any such Overpayment shall be treated for all
purposes as a loan to the Executive which the Executive shall repay to the
Company, together with interest at the applicable federal rate provided for in
Section 7872(E)(2) of the Code; provided, however, that no amount shall be
payable by the Executive to the Company if and to the extent such payment would
not reduce the amount which is subject to taxation under Section 4999 of the
Code. In the event that the Accounting Firm determines that an Underpayment has
occurred, any such Underpayment shall be promptly paid by the Company to or for
the benefit of the Executive, together with interest at the applicable federal
rate provided for in Section 7872(f)(2) of the Code.

customer or acquisition prospect of the Company derived from any customer list,
customer lead, mail, printed matter or other information secured from the
Company or its present or past employees or (iii) in any other manner use any
customer lists or customer leads, mail, telephone numbers, printed material or
other information of the Company relating thereto.
