              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. On July 30, 1999, Allied completed the acquisition of
Browning-Ferris Industries, Inc. ("BFI") for approximately $7.7 billion of cash
and the assumption of approximately $1.9 billion of BFI debt. Prior to the
acquisition, BFI was the second largest nonhazardous solid waste company in
North America and provided integrated solid waste management services including
residential, commercial and industrial collection, transfer, disposal and
recycling. (See Note 2).

     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, 1998, 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 conjunction with the Company's Annual Report on Form
10-K/A as filed on July 13, 1999 for the year ended December 31, 1998. The
condensed consolidated financial statements as of September 30, 1999, and for
the three and nine months ended September 30, 1998 and 1999 reflect, in the
opinion of management, all adjustments (which include normal recurring
adjustments) necessary to fairly state the financial position and results of
operations for such periods.

     Operating results for interim periods are not necessarily indicative of the
results for full years. These condensed consolidated financial statements should
be read in conjunction with the consolidated financial statements of Allied for
the year ended December 31, 1998 and the related notes thereto included in the
Company's Annual Report on Form 10-K filed with the SEC on March 31, 1999 and
amended on July 13, 1999.

     There have been no significant additions to or changes in accounting
policies of the Company since December 31, 1998, except for the change in the
Company's capitalized interest policy described below. For a description of all
other accounting policies, see Note 1 of Notes to Consolidated Financial
Statements for the year ended December 31, 1998 in the Company's Annual Report
on Form 10-K/A.

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

CHANGE IN ACCOUNTING PRINCIPLE

     Management evaluated the capitalized interest policy of the Company to
assess the comparability of the calculation with the change in the business
strategy resulting from the acquisition of BFI. As a result of this assessment,
the Company changed the method of calculating capitalization of interest under
Statement of Financial Accounting Standard No. 34, Capitalization of Interest
Cost ("SFAS 34"). Previously, interest was capitalized using a method that
defined the area of a landfill under development as all acreage considered
available for development. Actual acquisition, permitting and construction costs
incurred related to the area under development qualified for interest
capitalization. Any costs incurred related to areas already developed and
accepting waste no longer qualified for interest capitalization. Under the new
methodology, the area of a landfill under development is defined as only the
portion of the permitted acreage currently undergoing active cell development.
The effect of this change in definition is to substantially reduce the acreage
qualifying for interest capitalization. The costs upon which interest is
capitalized continue to include the actual acquisition, permitting and
construction costs incurred for cell development. Consistent with the prior
policy, as

                                        5

                         ALLIED WASTE INDUSTRIES, INC.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

construction of an area is completed and the area becomes available for use, the
cell no longer qualifies for interest capitalization.

     The adoption of this method, which is accounted for as a change in
accounting principle, reflects the change in the operating strategy of the
Company as a result of the BFI acquisition. Previously the Company's strategy
was focused on the acquisition and development of waste disposal capacity.
Through the BFI acquisition, the Company substantially achieved its previous
strategy and will now focus on the increased utilization of landfill capacity.

     The impact of the change in accounting principle is a cumulative charge of
approximately $64.3 million, after tax benefit which is included in income for
the nine months ended September 30, 1999. The effect of the change on the nine
months ended September 30, 1999 was to decrease net income before cumulative
effect of a change in accounting principle $20.7 million ($0.11 per share) and
net income $85.0 million ($0.45 per share). The pro forma amounts shown on the
Condensed Consolidated Statements of Operations reflect the effect of
retroactive application on capitalized interest in the prior periods that would
have been recorded had the new method been in effect during these periods and
the related income tax benefit.

     The effect of the change on the first and second quarters of 1999 is as
follows (in thousands except per share amounts):

ACQUISITION RELATED AND UNUSUAL COSTS

1999

     During the first nine months of 1999, the Company recorded $549.8 million
of acquisition related and unusual costs associated with the $9.6 billion
acquisition of BFI, which was accounted for as a purchase. (See Note 2.) The
costs primarily relate to environmental related matters, litigation liabilities,
risk management liabilities, loss contract provisions, transition costs, the
write-off of deferred costs relating to the acquisition and $31.8 million
impairment loss to reduce the carrying value of assets held for sale. These
costs are comprised of the following:

          The Company recorded a charge of approximately $265 million related to
     changes in estimates of environmental liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations were performed by
     third-party and in-house engineers. Based on these assessments, the Company
     made changes in accounting estimates

                                        6
<PAGE>   8
                         ALLIED WASTE INDUSTRIES, INC.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     of approximately (i) $136 million associated with the Superfund accrual for
     over 150 CERCLA cases in which BFI is involved, (ii) $28 million associated
     with the remedial accrual for six sites in which BFI is involved with
     remedial action plans, (iii) $56 million associated with the environmental
     accrual for various containment and treatment matters at 76 active or
     closed BFI landfills and (iv) $45 million associated with the accrual for
     the remedial and closure requirements of four BFI hazardous waste
     facilities.

          Management believes the environmental accrual as of September 30, 1999
     represents the most probable outcome of these matters. The Company does not
     expect that adjustments to these estimates, which are reasonably possible
     in the near term and that may result in changes to recorded amounts, will
     have a material effect on the Company's consolidated liquidity, financial
     position or results of operations. As of September 30, 1999, the Company
     believes that it is reasonably possible that the ultimate outcome of the
     environmental matters could result in approximately $33 million of
     additional liability.

          The Company recorded a charge of approximately $93 million related to
     changes in estimates of litigation liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations and outstanding litigation
     were performed by third-party and in-house legal counsel. The Company
     evaluated over 150 cases involving employee-related matters, insurance
     related matters, regulatory matters, collection matters and contract
     disputes. Accordingly, Allied increased the litigation accrual based on the
     most probable loss to be incurred for these outstanding cases.

          Management believes the litigation accrual as of September 30, 1999
     represents the most probable outcome of outstanding assessments, claims and
     cases. The Company does not expect that adjustments to estimates, which are
     reasonably possible in the near term and that may result in changes to
     recorded amounts, will have a material effect on the Company's consolidated
     liquidity, financial position or results of operations. As of September 30,
     1999, the Company believes that it is reasonably possible that the ultimate
     outcome of the litigation matters could result in approximately $10 million
     of additional liability.

          The Company recorded a charge of approximately $20 million related to
     changes in estimates of the self-insurance accruals based on the results of
     a third party actuarial review performed in connection with due diligence
     and integration of the BFI acquisition.

          In connection with the integration of the BFI acquisition, the Company
     reviewed BFI's existing contracts. Several contracts reviewed were in a
     loss position when the direct costs (excluding any fixed costs) required to
     be incurred to complete the contract were deducted from the revenue to be
     generated over the life of the contract. Consistent with Allied's
     accounting policies, the Company recorded a charge of approximately $35
     million related to changes in estimates of required accrued losses for the
     excess of costs over revenues of the identified contracts.

          As a result of the acquisition of BFI in the third quarter 1999,
     management reassessed its market development program and decided that
     certain companies that were being targeted for acquisition will no longer
     be pursued. Accordingly, the company wrote off $26 million of deferred
     charges previously incurred in connection with these potential
     acquisitions. Additionally, the Company expensed $34 million of commitment
     fees paid in connection with a portion of the financing of the BFI
     acquisition. These fees were associated with funds that were not drawn due
     to alternative financing arrangements. These fees were expensed because
     committed financing was a condition of the signing of the merger agreement
     with BFI and the debt associated with these fees was not incurred.

          In connection with the integration plan for BFI, Allied identified and
     notified approximately 1,500 employees that they will be retained for a
     specified period, generally not exceeding nine months from the acquisition
     date, to perform transition and integration related functions. Subsequent
     to the specified time period, they will be terminated. Additionally, Allied
     identified certain offices and operations which are

                                        7
<PAGE>   9

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     duplicative and is in the process of consolidating these operations. As
     these transition costs are not accruable until committed or paid,
     approximately $35 million of transition costs were expensed during the
     third quarter. Additionally, the Company accrued approximately $9 million
     of committed transition costs during the third quarter. The Company
     estimates that it may incur approximately $200 million of additional
     transition expenses associated with the integration of BFI over the
     subsequent quarters.

          Any subsequent changes in estimates of acquisition related and unusual
     costs will be included in the acquisition related and unusual costs caption
     of the statement of operations in the period in which the change in
     estimate is made. To date, no significant changes in estimates have been
     made related to these costs.

1998

     During the year ended December 31, 1998, the Company recorded acquisition
related and unusual costs in the amount of $247.9 million. These costs consist
of transaction and deal costs, employee severance and transaction costs,
environmental related matters, litigation liabilities, regulatory compliance
matters, restructuring and abandonment costs and loss contract provisions. The
Company does not anticipate that future costs to be incurred in connection with
the 1998 acquisitions will be significant as the restructuring and transition
activities associated with these acquisitions has been substantially completed
as of December 31, 1998. The 1998 acquisition related and unusual costs
discussed below predominantly relate to acquisitions accounted for as
poolings-of-interests and consist of the following:

          Direct transaction and deal costs of $51.2 million including
     investment banker, attorney, accountant, environmental assessment and other
     third-party fees. Approximately $11.7 million was accrued at December 31,
     1998 and was paid in the first six months of 1999.

          Employee severance and transition costs of $73.6 million consist of
     $39.3 million in termination payments made to employees of acquired
     companies based on change of control provisions in preexisting contracts
     and $34.3 million of costs associated with severance payments under exit or
     integration plans implemented in connection with acquisition made during
     1998. Exit plans primarily related to the elimination of duplicate
     corporate and administrative offices of companies acquired. Integration
     plans included the combination of field activities for human resource,
     accounting, facility maintenance, health and safety compliance and customer
     service activities of companies acquired with field activities similar to
     those of the Company. The exit and integration plans called for the
     termination of approximately 800 employees who performed managerial, sales,
     administrative support, maintenance and repair, or hauling and landfill
     operations duties. All employees were identified and notified of their
     severance or transition benefits at the time management approved the plan,
     which occurred at or around the time of the acquisitions. Approximately
     $10.1 million was accrued at December 31, 1998, the majority of which has
     been paid in 1999.

          Environmental related matters, litigation liabilities and regulatory
     compliance matters assumed in acquisitions totaled $73.4 million.
     Subsequent to the acquisitions, the Company made certain changes in
     accounting estimates due to events and new information becoming available
     for environmental liabilities of approximately $41.1 million, litigation
     liabilities of approximately $20.8 million and regulatory compliance
     liabilities of approximately $11.5 million.

     As part of the Company's acquisition due diligence process, environmental
assessments were performed at the time of acquisition by third-party and
in-house engineers. The assessments were performed at over 150 operating sites
owned or used by the 54 companies acquired by Allied in 1998. Additional
environmental liabilities were accrued based on the results of the assessments
and represent the most probable outcome of these identified contingent matters.
$27.1 million of the additional accrued environmental liability was comprised of
required remedial activities identified at 28 separate locations. These
locations include eight

                         ALLIED WASTE INDUSTRIES, INC.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

landfills acquired by Allied, 15 landfills not owned by Allied, but used for
disposal by collection companies acquired, and transfer stations and maintenance
facilities acquired. Required remedial activities include the removal and
disposal of contaminated soil and hazardous waste and legal and administrative
costs of the settlement of Superfund claims. The additional $14 million of
environmental accruals related to removal and treatment of leachate at
landfills, the level of which exceeded permitted amounts at seven of the
acquired landfills. At December 31, 1998, approximately $41.1 million and $15.8
million was accrued for environmental matters and legal and regulatory
compliance matters, respectively, which are expected to be disbursed in future
periods.

     The change in estimate relating to litigation and regulatory compliance
liabilities was accrued based on legal due diligence performed by in-house and
outside legal counsel for acquired companies at the time of acquisition and the
determination of the most probable loss incurred. As a result of this legal due
diligence, the Company identified 14 companies acquired in business combinations
accounted for as poolings-of-interest which had an aggregate of 54 asserted and
unasserted claims involving matters such as contract disputes, employment
related disputes, real and personal property and sales tax issues and billing
disputes. Additionally, the Company identified regulatory compliance issues
related to 12 companies acquired, which included citations for certain state and
federal health, safety and transportation violations and the associated costs of
fines, assessments and required maintenance costs to bring facilities and
equipment into compliance.

     Management believes the accrual as of December 31, 1998 for legal and
regulatory compliance matters represents the most probable outcome of
outstanding assessments and claims. The Company does not expect that adjustments
to estimates related to the 1998 acquisitions will have a material effect on the
Company's consolidated liquidity, financial positions or results of operations.
At December 31, 1998, the Company believes that it is reasonably possible that
the ultimate outcome of the legal and regulatory compliance matters could result
in approximately $5 million of additional liability.

     Restructuring and abandonment costs were $42.1 million in business
combinations accounted for as pooling-of-interests. Costs to relocate redundant
operations and to transition them to common information systems were $23.1
million. Redundant operations consisted primarily of activities for human
resources, accounting, facility maintenance, health and safety compliance and
customer service which were performed in field offices of companies acquired.
Abandonment costs and losses on the disposal of duplicate revenue producing
assets relating to specifically identified transfer stations and recycling
facilities were $8.8 million. Revenue and net operating income of the abandoned
operations represented less than one percent of the Company's consolidated
amounts. Additionally, $10.2 million of costs were incurred for the disposition
of redundant non-revenue producing assets. This includes $7.6 million that was
accrued at December 31, 1998, and in accordance with exit and integration plans
is expected to be paid in 1999. This accrual is for payments under
non-cancelable lease agreements for corporate offices to be vacated and other
costs to close corporate facilities after operations have ceased under exit
plans implemented during 1998 at five companies acquired.

     Loss contract provisions were $7.6 million for losses associated with
collection contracts and other contractual obligations assumed in acquisitions.
Approximately $5 million remained accrued at December 31, 1998 and was paid as
of September 30, 1999.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards 133 -- Accounting for Derivative
Instruments and Hedging Activities ("SFAS 133"). This statement establishes
accounting and reporting standards for derivative instruments, including
derivative instruments embedded in other contracts, and for hedging activities.
The statement, to be applied prospectively, was to have been effective for the
Company's quarter ending March 31, 2000. In June 1999, the FASB issued Statement
of Financial Accounting Standards 137 -- Accounting for Derivative Instruments

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Hedging Activities -- Deferral of the Effective Date of FASB Statement No. 133.
This statement deferred the effective date of SFAS 133 to the Company's quarter
ending March 31, 2001. The Company is currently evaluating the impact of SFAS
133 on its future results of operations and financial position.

     During 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5 Reporting on the Costs of Start-Up Activities ("SOP
98-5"). SOP 98-5 requires costs of start-up activities and organization costs to
be expensed as incurred. The new statement is effective for fiscal years
beginning after December 15, 1998. The Company adopted this statement effective
January 1, 1999. Initial application of SOP 98-5 is required to be reported as
the cumulative effect of a change in accounting principle. Adoption of this
standard did not have a material impact on the Company's financial position or
results of operations.

2. BUSINESS COMBINATIONS AND DIVESTITURES

     Acquisitions accounted for under the pooling of interests method are
reflected in the results of operations as if the acquisition occurred on the
first day of the earliest year presented. Acquisitions accounted for under the
purchase method are reflected in the results of operations since the effective
date of the acquisition. For those acquisitions accounted for using the purchase
method, the Company allocates the cost of the acquired business to the assets
acquired and liabilities assumed based upon their estimated fair values. These
estimates are revised during the allocation period as necessary when, and if,
information regarding contingencies becomes available to define and quantify
assets acquired and liabilities assumed. The allocation period varies but does
not exceed one year. To the extent contingencies are resolved or settled during
the allocation period, such items are included in the revised allocation of the
purchase price. Purchase accounting adjustments, acquisition related costs and
other possible charges that may arise from the acquisitions may materially
impact our future consolidated financial position and consolidated financial
results of operations.

     On July 30, 1999, the Company completed the acquisition of BFI for
approximately $7.7 billion of cash and the assumption of approximately $1.9
billion of BFI debt. Prior to the acquisition, BFI was the second largest
nonhazardous solid waste company in North America and provided integrated solid
waste management services including residential, commercial and industrial
collection, transfer, disposal and recycling. As of the date of acquisition, BFI
serviced approximately 7.3 million customers through a network of 221 collection
companies, 86 transfer stations, 91 landfills, and 102 recycling facilities and
had annual revenues of approximately $4.2 billion.

     The cash consideration for the acquisition of BFI was financed by the
proceeds from the issuance of the $1.0 billion 6.5% senior convertible preferred
stock, the proceeds from the issuance of the $2.0 billion 10% Senior
Subordinated Notes, and the proceeds from the $5.6 billion senior secured credit
facility and the asset sale term loan.

     The acquisition of BFI has been accounted for as a purchase and,
accordingly, the operating results of BFI have been included in the Company's
consolidated financial statements since the date of acquisition. The excess of
the aggregate purchase price over the fair market value of net assets acquired
of approximately $6.8 billion is being amortized over 40 years using the
straight-line method.

     In the first nine months of 1999, the Company acquired two companies in
transactions accounted for as poolings-of-interests. As the effect of these
business combinations was not significant, prior period financial statements
were not restated to include historical operating results of the acquired
companies.

     In the first nine months of 1999, the Company sold certain assets for
approximately $125.8 million. These assets were included in assets held for sale
as of December 31, 1998.

3. ASSETS HELD FOR SALE

ALLIED ASSETS

     The ability to successfully implement the Company's vertical integration
business plan is a key consideration in determining whether the Company will
continue to operate in a specific market. In the normal course of business, the
Company has exited markets in which the execution of the vertical integration
business plan was not practicable.

     In October 1998, management formalized plans to dispose of certain
operating districts (the "Operating Districts") that represented non-core or
non-integrated operations. The Company had entered into agreements to sell these
operations and in accordance with Statement of Financial Accounting Standard
121 -- Accounting for the Impairment of Long-lived Assets and Long-lived Assets
to Be Disposed Of ("SFAS 121"), recorded an impairment loss during the fourth
quarter of 1998 to reduce the carrying value of the assets to net realizable
value including an accrual for the cost of disposal. The Company completed the
sale of these assets during the first six months of 1999.

     In July 1999, management formalized plans to dispose of certain operations
required to be divested by governmental order as a condition for approval of the
acquisition of BFI (the "Allied Divestitures"). Additionally, management has
identified other Allied operating districts (the "Allied Operations") in which
the Company's vertical integration plan is not practicable as a result of the
BFI transaction. In accordance with SFAS 121, an impairment loss of $31.8
million was recorded during the third quarter of 1999 to reduce the carrying
value of the assets to the net realizable value including an accrual for the
cost of disposal. The Company expects to complete these transactions during
2000.

     The results of operations before depreciation and amortization of the
Operating Districts, the Allied Divestitures and Allied Operations included in
consolidated operating income, in accordance with SFAS 121, was approximately
$6.6 million during the nine months ended September 30, 1999. During this same
period, the Company excluded from consolidated statements of operations, in
accordance with SFAS 121, depreciation and amortization relating to assets held
for sale in the amount of $5.0 million.

BFI ASSETS

     Concurrent with the acquisition of BFI, certain BFI operations were
identified prior to the acquisition of BFI by management as non-core or
non-integrated operations and are expected to be divested along with certain
operations required by governmental order to be divested. These operations
include BFI's Canadian operations, medical waste operations, gas systems
operations and certain solid waste operations (collectively, the "BFI
Divestitures"). The sales of these operations are being accounted for in
accordance with Emerging Issues Task Force Issue 87-11 -- Allocation of Purchase
Price to Assets to Be Sold. The BFI Divestitures are being carried at the net
realizable value based on the current terms of transactions expected to be
closed in the next several months including accruals for cost of disposal,
operating income and allocable interest expense. Accordingly, $25.9 million of
consolidated operating income and $20.4 million of allocable interest expense
related to the BFI Divestitures was excluded from the consolidated statements of
operations for the nine

     In December 1998, Allied Waste North America, Inc. ("Allied NA"; a wholly
owned consolidated subsidiary of Allied) issued an aggregate of $1.7 billion of
senior notes consisting of $225 million 7 3/8% senior notes due 2004 (the "Five
Year Senior Notes"), $600 million 7 5/8% senior notes due 2006 (the "Seven Year

Senior Notes") and $875 million 7 7/8% senior notes due 2009 (the "Ten Year
Senior Notes" and collectively the "1998 Senior Notes") in a Rule 144A offering
which were subsequently registered for public trading with the SEC in January
1999. Interest accrued on the 1998 Senior Notes is payable semi-annually on
January 1 and July 1 beginning on July 1, 1999. The Company used the net
proceeds from the 1998 Senior Notes to fund the purchase of the 1996 Notes and
the Senior Discount Notes pursuant to tender offers the Company commenced in
November 1998 and completed in December 1998, to repay borrowings outstanding
under the Senior Credit Facility and certain capital lease obligations, and for
general corporate purposes. The 1998 Senior Notes are guaranteed by the Company
and substantially all of Allied NA's current and future subsidiaries, the
guarantees of which are expressly subordinated to the guarantees of Allied NA's
Credit Agreement.

     In June 1998 the Company repaid $486.8 million outstanding under the 1997
Credit Agreement and entered into the Senior Credit Facility (defined herein).
The Senior Credit Facility provides a $800 million five year senior secured
revolving credit facility (the "Revolving Credit Facility") and a $300 million
five year senior secured term loan facility (the "Term Loan Facility" and
together with the Revolving Credit Facility, the "Senior Credit Facility").

     In connection with the BFI acquisition in July 1999, the Company repaid the
Senior Credit Facility and entered into a new credit facility (the "1999 Credit
Facility"). The 1999 Credit Facility provides a $1.5 billion six-year revolving
credit facility, a $556 million two-year asset sale term loan (the "Asset Sale
Term Loan"), a $1,750 million six-year tranche A term loan (the "Tranche A Term
Loan"), a $1,250 million seven-year tranche B term loan (the "Tranche B Term
Loan"), a $1,500 million eight-year tranche C term loan (the "Tranche C Term
Loan") and a $500 million eight-year tranche D term loan (the "Tranche D Term
Loan").

     The 1999 Credit Facility bears interest, at (a) an Alternate Base Rate, or
(b) a Eurodollar Rate, both terms defined in the 1999 Credit Facility, plus, in
either case, an applicable margin and may be used for acquisitions, the issuance
of letters of credit, working capital and other general corporate purposes. Of
the $1.5 billion available under the Revolving Credit Facility, no more than
$800 million may be used to support the issuance of letters of credit. As of
September 30, 1999, $1.1 billion was available for withdrawal on this facility.

     The Company is required to make prepayments on the 1999 Credit Facility
upon completion of certain asset sales and issuances of debt or equity
securities. Required prepayments are to be made based on a percentage of the net
proceeds of any debt incurrence or equity issuance. Proceeds of an issuance of
debt or equity are first applied to reduce borrowings under the Tranche D Term
Loan, second to reduce borrowings under the Asset Sale Term Loan and third to
reduce the borrowings under the Tranche A, B and C Term Loans on a pro rata
basis. Proceeds from asset sales are to be applied first to reduce borrowings
under the asset sale term loan, second to reduce the borrowings under the
Tranche A, B and C Term Loans on a pro rata basis. When proceeds are received
from an asset sale, if there are no outstanding Asset Sale Term Loan borrowings
and the Tranche D Term Loan has been repaid, then the proceeds may be applied to
reduce borrowings under the term loans.

     In July 1999, Allied NA issued approximately $2.0 billion of senior
subordinated notes (the "1999 Notes") in a Rule 144A offering. Interest accrues
on the 1999 Notes at an interest rate of 10% per annum, payable semi-annually on
May 1 and November 1 beginning on November 1, 1999. The Company used the
proceeds from the 1999 Notes as partial financing of the acquisition of BFI. The
1999 Notes are guaranteed by the Company and substantially all of Allied NA's
current and future subsidiaries, the guarantees of which are subordinated to all
current and future indebtedness except indebtedness that expressly provides that
it is not senior to the guarantees.

     In connection with the BFI acquisition on July 30, 1999, the Company
assumed all of BFI's debt securities with the exception of commercial paper that
was paid off in connection with the acquisition. BFI's

debt securities were recorded at their fair market values as of the date of the
acquisition in accordance with Emerging Issues Task Force Issue
98-1 -- Valuation of Debt Assumed in a Purchase Business Combination. The effect
of revaluing the debt securities formerly owned by BFI resulted in an aggregate
discount from the face amount of $137.0 million.

     The debt assumed in connection with the acquisition, includes 6.08% Market
Value Put Securities (MVPs) with a face amount of $250 million due January 18,
2002, 6.10% Senior Notes with a face amount of $156.7 million due January 15,
2003, 6.375% Senior Notes with a face amount of $161.2 million due January 15,
2008, 7.875% Senior Notes with a face amount of $69.5 million that mature on
March 15, 2005, 9.25% Debentures with a face amount of $99.5 million that mature
on May 1, 2021, 7.40% Debentures with a face amount of $360.0 million due
September 15, 2035 and solid waste revenue bond obligations with an aggregate
face amount of $256.1 million, a weighted average interest rate of approximately
5.63% and various maturity dates through the year 2027.

     The MVPs have a mandatory put on January 18, 2000. First National Bank of
Chicago holds an option to purchase the MVPs, and if the Company chooses, to
remarket the MVPs on that date for an additional two-year term. If First
National Bank of Chicago does not exercise its option to purchase the MVPs on
January 18, 2000, they will be purchased by the Company on that date.

     The 7.40% Debentures are not subject to any sinking fund and may be
redeemed as a whole or in part, at the option of the Company at any time. The
redemption price is equal to the greater of (i) the principal amount of the
debentures and (ii) the present value of future principal and interest payments
discounted at a rate specified under the terms of the indenture.

     The 6.10% Senior Notes, 6.375% Senior Notes and 9.25% Debentures are not
redeemable prior to maturity and are not subject to any sinking fund.

fixed rate of approximately 5.76% plus applicable margins.

DEBT COVENANTS

     The Company's 1999 Credit Facility, contains certain financial covenants,
including, but not limited to, an EBITDA ratio, and an interest expense coverage
ratio. Additionally, these covenants limit among other things, the ability of
the Company and of its subsidiaries to incur additional indebtedness and liens,
make acquisitions and purchase fixed assets above certain amounts, pay
dividends, make optional prepayments on certain subordinated indebtedness, make
investments, loans or advances, enter into certain transactions with affiliates
or consummate a merger, consolidation or sale of all or substantially all of its
assets. At September 30, 1999, Allied was in compliance with all applicable
covenants.

     The 1998 Senior Notes and the 1999 Notes contain certain financial and
operating covenants and restrictions which may in certain circumstances limit
the ability of the Company to complete acquisitions, pay dividends, incur
indebtedness, make investments and take certain other corporate actions.

     Substantially all subsidiaries of the Company are jointly and severally
liable for the obligations under the 1998 Senior Notes, the 1999 Notes and the
1999 Credit Facility through unconditional guarantees issued by current and
future subsidiaries which are all, except in one minor case, wholly-owned by the
Company. In addition, the 1999 Credit Facility is secured by substantially all
the personal property and a pledge of the stock of substantially all of the
Company's present and future subsidiaries.

7. CLOSURE, POST-CLOSURE AND ENVIRONMENTAL COSTS

CLOSURE AND POST-CLOSURE COSTS

     The net present value of the closure and post-closure liability is
calculated assuming inflation of 2.0% and a risk-free capital rate of 6.5%.
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, in accordance with Subtitle D, is $2.8 billion,
adjusted for inflation, as shown below, while the present value of such estimate
is $1.1 billion. At December 31, 1998 and September 30, 1999, accruals for
landfill closure and post-closure costs (including costs assumed through
acquisitions) were approximately $154.5 million and $542.1 million,
respectively. The estimated remaining lives, based on current waste flows, range
from 1 to over 75 years, with an estimated average remaining life of
approximately 30 years.

     The Company's estimate of total future payments for closure and
post-closure liabilities as of September 30, 1999 for currently owned and
operated landfills is as follows (in thousands):

ENVIRONMENTAL COSTS

     In connection with the acquisition of companies, Allied engages an
independent environmental consulting firm to assist in conducting an
environmental assessment of companies acquired from third parties. The

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

ultimate amounts for environmental liabilities cannot be determined and
estimates of such liabilities made by the Company, after consultation with its
independent environmental engineers, require assumptions about future events due
to a number of uncertainties including the extent of the contamination, the
appropriate remedy, the financial viability of other potentially responsible
parties and the final apportionment of responsibility among the potentially
responsible parties. Where the Company has concluded that its estimated share of
potential liabilities is probable, a provision has been made in the consolidated
financial statements. Since the ultimate outcome of these matters may differ
from the estimates used in the Company's assessment to date, the recorded
liabilities are periodically evaluated, as additional information becomes
available to ascertain that the accrued liabilities are adequate. The Company
has determined that the recorded liability for environmental matters as of
September 30, 1999 of approximately $458.0 million represents the most probable
outcome of these contingent matters.

8. EMPLOYEE BENEFIT PLANS

     Effective July 30, 1999, in connection with the acquisition of BFI, the
Company assumed two defined benefit retirement plans covering substantially all
BFI employees in the United States, except for certain employees subject to
collective bargaining agreements. These retirement plans were amended on July
30, 1999 to freeze future credited service, but interest credits will continue
to accrue, for all non-union participants. Union participants will continue to
receive 2% annual service credits. The benefits for these plans are based on
years of service and the employee's compensation. The Company's general funding
policy for these plans is to make annual contributions to the plans equal to the
actuary's recommended contribution, as required.

     The BFI San Mateo Pension Plan covers substantially all employees of this
location. Benefits are based on the employee's years of service and compensation
using the average of earnings over the highest five consecutive calendar years
out of the last fifteen years of service.

     For both plans, an actuarial valuation report was prepared as of July 30,
1999 and used, as permitted by Statement of Financial Accounting Standards No.
132, Employers' Disclosures about Pensions and Other Postretirement Benefits
("SFAS No. 132") for the following disclosures.

     As the majority of the benefits were frozen as of the date of acquisition
and the plans are in a prepaid position, the current year expense is not
expected to be material to the Company's results of operations.

OTHER POSTRETIREMENT BENEFITS

     The Company assumed in connection with the acquisition of BFI a frozen and
unfunded postretirement benefit plan which provides for employees participating
in its medical plan to receive a monthly benefit after retirement based on years
of service. The Company has accrued the actuarially-determined accumulated
postretirement benefit obligation of approximately $12 million at September 30,
1999. Current year expense is not expected to be material to the Company's
results of operations.

9. REDEEMABLE PREFERRED STOCK

     In connection with the BFI acquisition, the Company's Board of Directors
adopted a resolution creating a series of one million shares of preferred stock
having a par value of $0.10 per share. These shares were designated as Series A
Senior Convertible Preferred Stock ("Preferred Stock") and are entitled to vote
on, among other things, all matters on which the holders of Common Stock are
entitled to vote. Each share of Preferred Stock has the number of votes equal to
the number of shares of Common Stock then issuable upon conversion, assuming
stockholder approval is obtained to permit conversion of the Preferred Stock
into Common Stock ("Stockholder Approval"). Assuming Stockholder Approval is
received prior to January 30, 2000, shares of Preferred Stock will be entitled
to cumulative quarterly dividends in an amount equal to 6.5% per annum of the
sum of liquidation preference plus accrued but unpaid dividends for prior
quarters. If dividends are not paid in cash, the liquidation preference of the
Preferred Stock increases by any accrued and unpaid dividends.

     The Preferred Stock has a redemption price of $1,000 per share, together
with any accrued and unpaid dividends. Redemption of the Preferred Stock is at
the option of the Company in whole but not in part if Stockholder Approval is
obtained prior thereto, at any time on or after July 30, 2004. After July 30,
2002, the Company has the right to redeem the Preferred Stock in whole, but not
in part, at the redemption price only if the current market price exceeds $27
per share.

     If Stockholder Approval is obtained, the Preferred Shareholders will have
the right to convert each share of Preferred Stock into the number of shares of
Common Stock obtained by dividing the redemption price plus any accrued and
unpaid dividends on the conversion date by the conversion price of $18 per
share, subject to customary anti-dilution adjustments. Upon a change in control,
Allied is required to make an offer to purchase for cash all shares of Preferred
Stock at 101% of liquidation preference plus accrued but unpaid dividends.

     As of September 30, 1999, the dividends accrued and unpaid on the Preferred
Stock are approximately $11.1 million or $11,119 per share.

10. COMMITMENTS AND CONTINGENCIES

     The Company is subject to extensive and evolving laws and regulations and
has implemented its own environmental safeguards to respond to regulatory
requirements. In the normal course of conducting its operations, Allied may
become involved in certain legal and administrative proceedings. Some of these
actions may result in fines, penalties or judgements against the Company, which
may have an impact on earnings for a particular period. Management expects that
such matters in process at September 30, 1999, which have not been accrued in
the consolidated balance sheet, will not have a material adverse effect on the
Company's consolidated liquidity, financial position or results from operations.

     In connection with certain acquisitions, the Company has entered into
agreements to pay royalties based on waste tonnage disposed at specified
landfills. The royalties are generally payable quarterly and amounts earned, but
not paid, are accrued in the accompanying condensed consolidated balance sheets.

</TABLE>

     Rental expense under such operating leases was approximately $13.9 million,
$8.7 million and $22.2 million for the year ended December 31, 1998, and the
nine months ended September 30, 1998 and 1999, respectively.

     The Company has entered into employment agreements with certain of its
executive officers for periods up to five years. The Company has agreed to
severance pay amounts equal to a multiple of defined compensation under certain
circumstances. In the event of a material change in control or termination of
all executive officers under such agreements, Allied would be required to make
payments of approximately $10.7 million, in addition to a reimbursement payment
to eliminate the effect of any excise taxes associated with this payment.

     As a condition of the merger agreement among Allied and BFI, the Company is
required to provide severance benefits to certain employees of BFI who do not
have employment agreements and who would not otherwise receive severance pay
upon termination, if terminated within 12 months following the date of
acquisition.

     Allied carries a broad range of insurance coverage for protection of its
assets and operation from certain risks including environmental impairment
liability insurance for certain landfills.

     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 or 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 September 30, 1999, the Company had outstanding
approximately $1.4 billion in financial assurance instruments, represented by
$603.8 million of performance bonds, $649.2 million of insurance policies, $90.7
million of letters of credit and $52.0 million of trust deposits. During 1999,
the Company expects to be required to provide approximately $1.4 billion of
financial assurance instruments relating to the Company's landfill operations
and collection contracts.

     Certain of the Company's subsidiaries have 50% ownership interests in
American Ref-Fuel partnerships that construct, own and operate facilities which
generate and sell electricity from the incineration of solid waste.
Substantially all of the remaining ownership interests are held by Duke/UAE
Ref-Fuel LLC, an entity indirectly owned 65% by Duke Capital Corporation ("Duke
Capital") and 35% by United American Energy Corporation. The five facilities
currently in commercial operation under this ownership structure are located in
Hempstead, New York, Essex County in New Jersey, Preston, Connecticut, Niagara
Falls, New York and Rochester, Massachusetts. Financing arrangements for four of
these projects include agreements with the Company and Duke Capital to each
severally fund one-half of each partnership's cash deficiencies resulting from
the partnership's failure to perform.

     With respect to the facilities located in Hempstead, New York, Essex County
in New Jersey and Preston, Connecticut, the Company and Duke Capital generally
will not be required to fund cash deficiencies

associated with waste deliveries by the sponsoring municipality below certain
minimum levels, changes in law or termination of incineration service for
reasons other than default by the respective partnership. In the event of a
partnership default which results in termination of incineration service, the
Company may limit its financial obligations by partnership as follows:

          Hempstead, New York -- Funding of 50% of periodic payments related to
     outstanding debt. Average annual debt service on 50% of the debt over the
     next five years is $11 million. The Company has guaranteed $5 million of
     additional partnership debt and annual debt service on such debt is
     estimated to be $.2 million.

          Essex County in New Jersey -- Funding of 50% of cash deficiencies
     including debt service up to $50 to $100 million, depending upon the
     circumstances. Average annual debt service on 50% of the debt over the next
     five years is $10 million.

          Preston, Connecticut -- Funding of 50% of periodic payments related to
     outstanding debt. Average annual debt service on 50% of the debt over the
     next five years is $5 million.

     With respect to the facilities located in Niagara Falls, New York and
Rochester, Massachusetts, the Company may limit its financial obligations by
partnership as follows:

          Niagara Falls, New York -- Funding of 50% of partnership cash
     deficiencies relating to debt service. Average annual debt service on 50%
     of the debt over the next five years is estimated to be $3 million.

          SEMASS in Rochester, Massachusetts -- Under support agreements and
     guarantees (i) lending up to 50% of $5 million to the SEMASS Partnership
     under certain circumstances, (ii) deferring up to 50% of $7 million of
     operating cost reimbursement, and (iii) funding up to 50% of $5 million in
     operating damages. These obligations have been assigned to the lenders.
     Average annual debt service on 50% of the debt over the next five years is
     approximately $19 million.

11. INCOME TAXES

     The Company accounts for income taxes using a balance sheet approach
whereby deferred tax assets and deferred tax liabilities are determined based on
the differences in financial reporting and income tax basis of assets, other
than goodwill, and liabilities. The differences are measured using the income
tax rate in effect during the year of measurement.

     The Company and its subsidiaries file a consolidated federal income tax
return. Due to the acquisition of BFI on July 30, 1999, a tax return will be
required for BFI's short fiscal year (October 1, 1998 to July 30, 1999). After
July 30, 1999, BFI will be included in the Company's consolidated tax return. It
is projected that the short period return filed for BFI will generate both a net
operating loss and an excess capital loss. The balance sheet classification of
the tax effect of these items has been established based on certain assumptions
which could subsequently change. The Company believes that any changes will
result in balance sheet reclassifications only and will not impact future
results of operations.

     The acquisition of BFI resulted in an additional $6.8 billion of goodwill,
the amortization of which is not deductible for income tax purposes. The impact
of this amortization is reflected in the following reconciliation of the federal
statutory tax rate to the Company's effective rate. The impact of rate
annualization below is based on year end results.

13. SEGMENT REPORTING

     The Company classifies its operations into eight geographic regions:
Atlantic, Central, Great Lakes, Midwest, Northeast, Southeast, Southwest, and
West. The Company's revenues are derived from one industry segment, which
includes the collection, transfer, recycling and disposal of non-hazardous solid
waste. The Company evaluates performance based on several factors, of which the
primary financial measure is business segment earnings before interest, taxes,
depreciation and amortization ("EBITDA") and before acquisition related and
unusual costs and asset impairments. The accounting policies of the business
segments are the same as those described in the Organization and Summary of
Significant Accounting Policies (see Note 1). The tables below reflect certain
geographic information relating to the Company's operations for the three and
nine months ended September 30, 1998 and 1999 (in thousands):

16. SUBSEQUENT EVENTS

     On November 12, 1999, Allied completed the sale of BFI's medical waste
business to Stericycle for approximately $411 million in cash.

     In November of 1999, Allied announced that the sale of BFI's Canadian
operations to Waste Management, Inc. had been restructured into a group of asset
purchase and sale transactions under which the purchase and sales prices will
approximate $225 million. These transactions are expected to close in 2000.

     The Company signed a letter of intent for the sale of certain assets in
Chicago and Detroit to Superior Services, Inc. for approximately $209 million
and expects to close the transaction during the fourth quarter of 1999.

     Each of the pending transactions is subject to various conditions and,
therefore, there can be no assurance as to the closing or timing of the closing
of these transactions.

                      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

     Allied Waste Industries, Inc. ("Allied") has experienced significant
growth, a substantial portion of which has resulted from the acquisition of
solid waste businesses. Since January 1, 1992, Allied completed more than 225
acquisitions. In 1998, Allied acquired 54 businesses and, subsequent to 1998
through September 30, 1999, we have acquired 45 businesses. Allied's Condensed
Consolidated Financial Statements have been restated to reflect the acquisition
of companies accounted for using the pooling-of-interests method for business
combinations in 1998. The results of operations for the acquisitions accounted
for under the purchase method for business combinations are included in our
financial statements only from the applicable date of acquisition. As a result,
Allied believes its historical results of operations for the periods presented
are not directly comparable to its current results of operations.

     On July 30, 1999, we completed our previously announced acquisition of BFI.
As a result of the acquisition, each share of BFI common stock was converted
into the right to receive $45 in cash. Including assumed and refinanced debt,
the cost of acquiring BFI was approximately $9.6 billion. Financing for the
acquisition was obtained from $5.6 billion of credit facilities (the "New Credit
Facility"), the sale of $1.0 billion of newly issued senior convertible
preferred stock (the "Preferred Stock") and the sale of $2.0 billion of 10%
Senior Subordinated Notes due 2009 (the "1999 Notes"). With the completion of
the acquisition of BFI, Allied operates in 46 states and 64 markets and serves
approximately 9.9 million commercial and residential customers from a base of
assets including 166 landfills, 164 transfer stations, 129 recycling facilities
and 362 collection companies. Prior to the closing of this transaction, the sale
of BFI's investment in SITA was completed for $444 million in cash.

     In June 1998, Allied Waste North America, Inc. ("we" or "Allied NA"; a
wholly owned, consolidated subsidiary of Allied) completed the acquisition of
the Rabanco Companies ("Rabanco") in a transaction accounted for using the
pooling-of-interests method for business combinations. Rabanco provided solid
waste collection, recycling, transportation and disposal services in the Pacific
Northwest and generated annual revenue of approximately $160 million excluding
the effects of the internalization of waste volumes.

     In August 1998, we acquired Illinois Recycling Services, Inc. and its
affiliates ("Illinois Recycling") in a transaction accounted for using the
pooling-of-interests method for business combinations. Illinois Recycling
provided solid waste collection, recycling and transportation services primarily
in the Chicago metropolitan area and northern Indiana and generated annual
revenue of approximately $80 million excluding the effects of the
internalization of waste volumes.

     In October 1998, we acquired American Disposal Services, Inc. ("ADSI") in a
transaction accounted for using the pooling-of-interests method for business
combinations. ADSI was a vertically integrated solid waste management company
providing collection, transfer, recycling and disposal services to approximately
485,000 customers in 12 states, primarily in the Midwest and Northeast United
States and generated annual revenue of approximately $240 million, excluding the
effects of the internalization of waste volumes.

     In December 1998, we completed a private offering of an aggregate of $1.7
billion of senior notes consisting of $225 million 7 3/8% senior notes due 2004
(the "Five Year Senior Notes"), $600 million 7 5/8% senior notes due 2006 (the
"Seven Year Senior Notes") and $875 million 7 7/8% senior notes due 2009 (the
"Ten Year Senior Notes", and together with the Five Year Senior Notes and the
Seven Year Senior Notes, the "1998 Senior Notes"). We used the net proceeds from
the 1998 Senior Notes to fund the purchase of the Company's $525 million of
10.25% senior subordinated notes due 2006 (the "1996 Notes") and $418 million
face value 11.3% senior discount notes (the "Senior Discount Notes") pursuant to
tender offers the Company commenced in November 1998, to repay borrowings
outstanding under the Senior Credit Facility (as defined herein) and certain
capital lease obligations, and for general corporate purposes.

                                       29

     Subsequent to entering into a definitive merger agreement with BFI, we
entered into definitive agreements to divest certain non-core and non-integrated
assets including (i) the medical waste operations of BFI to Stericycle, Inc. for
approximately $411 million, (ii) the Canadian operations of BFI to Waste
Management, Inc. for approximately $225 million, (iii) certain assets of BFI Gas
Services, Inc. to Gas Recovery Systems, Inc. for approximately $63 million and
(iv) certain solid waste assets to Superior Services, Inc. and to Republic
Services, Inc. for an aggregate of approximately $609 million. Net proceeds from
these sales will be used to repay debt. Each of these transactions is subject to
various conditions and, therefore, there can be no assurance as to the closing
or timing of the closing of these transactions.

     Subsequent to the acquisition of BFI, management evaluated the Company's
capitalized interest policy to assess the comparability of the calculation with
the change in the business strategy resulting from the acquisition. Previously,
interest was capitalized based upon the area of a landfill under development
defined as all usable acreage for which permitting or construction activities
were in process. Under the new methodology, the area of the landfill under
development is defined as only the portion of the permitted acreage currently
undergoing active cell development. The effect of this change in definition is
to substantially reduce the acreage qualifying for interest capitalization. The
costs upon which interest is capitalized continue to include the actual
acquisition, permitting and construction costs incurred for cell development.
Consistent with the prior policy, as construction of an area is completed and
the area becomes available for use, the cell no longer qualifies for interest
capitalization. The adoption of this method which is accounted for as a change
in accounting principle reflects the change in the operating strategy of the
Company as a result of the BFI acquisition. Previously the Company's strategy
was focused on the acquisition and development of waste disposal capacity.
Through the BFI acquisition, the Company substantially achieved its previous
strategy and will now focus on the increased utilization of landfill capacity.
The impact of the change in accounting principle was a cumulative charge of
approximately $64.3 million, net of related income tax benefit.

GENERAL

     Revenues.  Our revenues are attributable primarily to fees charged to
customers for waste collection, transfer, recycling and disposal services. We
generally provide collection services under direct agreements with our 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. Our landfill operations include both company-owned landfills
and those operated for municipalities for a fee. In each geographic region in
which we are located, we provide collection, transfer and disposal services. The
following tables show for the periods indicated the percentage of our total
reported revenues attributable to services provided and revenues attributable to
geographic regions. We have restated the data below to give effect to
acquisitions that were accounted for using the pooling-of-interests method for
business combinations.

</TABLE>

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

(1) The portion of collection and third-party transfer revenues attributable to
    disposal charges for waste collected by us and disposed at our landfills has
    been excluded from collection and transfer revenues and included in landfill
    revenues.

     Our strategy is to develop vertically integrated operations to ensure
internalization of waste we collect and thus realize higher margins from our
operations. By disposing of waste at company-owned and/or operated landfills, we
retain the margin generated through disposal operations that would otherwise be
earned by third-party landfills. Approximately 63% of the waste we collect as
measured by disposal volumes was disposed of at landfills we own and/or operate
in the first nine months of 1999, which includes the results of operations of
BFI for two months. In addition, transfer stations are an integral part of the
disposal process. We locate our transfer stations in areas where our landfills
are outside of the population centers in which we collect waste. We transfer
this waste to long-haul trailers or railcars, which transport the waste
economically to our 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 our 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, we incur and capitalize certain
transaction costs 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. We routinely evaluate capitalized transaction and integration
costs, and we expense those costs related to acquisitions not likely to occur.
We expense indirect acquisition costs, such as executive salaries, general
corporate overhead and other corporate services, as incurred.

     We capitalize and amortize certain direct landfill development costs, such
as engineering, construction and permitting costs, based on consumed airspace.
We believe 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.
We cannot assure you whether we will be able to raise prices sufficiently to
offset these increased expenses. We expense all indirect landfill development
costs, such as executive salaries, general corporate overhead, public affairs
and other corporate services, as incurred.
                                       31
<PAGE>   33

     Closure and post-closure costs represent our financial commitment for the
regulatory required costs associated with our future obligations for final
closure, which is the closure of a cell of a landfill once the cell is no longer
receiving waste, and post-closure monitoring and maintenance of landfills, which
is usually required for up to 30 years after a landfill's final closure. We
establish closure and post-closure requirements based on the standards of
Subtitle D of the Resource Conservation and Recovery Act of 1976 as implemented
on a state-by-state basis. We base closure and post-closure accruals on
estimates to cap and cover a landfill, methane gas control, leachate management
and groundwater monitoring, and other operational and maintenance costs to be
incurred after the site discontinues accepting waste. We prepare site-specific
closure and post-closure engineering cost estimates annually for landfills owned
and/or operated by us for which we are responsible for closure and post-closure.

     We accrue and charge closure and post-closure costs based on accepted
tonnage as landfill airspace is consumed to ensure that the total closure and
post-closure obligations are fully accrued for each landfill at the time that
the site discontinues accepting waste and is closed. For landfills purchased, we
assess and accrue a closure and post-closure liability at the time we assume
closure responsibility based upon the estimated closure and post-closure costs
and the percentage of airspace utilized as of the date of acquisition. After the
date of acquisition, we accrue and charge closure and post-closure costs as
airspace is consumed. We update estimated closure and post-closure liabilities
annually based on assessments performed by in-house and independent
environmental engineers that management approves. Such costs may change in the
future as a result of permit modifications or changes in legislative or
regulatory requirements.

     We accrue closure and post-closure cost estimates based on the present
value of the future obligation. We discount future costs where we believe that
both the amounts and timing of related payments are reliably determinable. We
annually update our estimates of future closure and post-closure costs. We
account for the impact of changes, which are determined to be changes in
estimates on a prospective basis.

     We calculate the net present value of the closure and post-closure
commitment assuming inflation of 2.0% and a risk-free capital rate of 6.5%. We
accrete discounted amounts previously recorded to reflect the effects of the
passage of time. We currently estimate total future payments for closure and
post-closure to be $2.8 billion adjusted for inflation. The present value of
such estimate is $1.1 billion. At December 31, 1998 and September 30, 1999,
accruals for landfill closure and post-closure costs (including costs assumed
through acquisitions) were approximately $154.5 million and $542.1 million,
respectively. The accruals reflect relatively young landfills with estimated
remaining lives, based on current waste flows, that range from approximately 1
to over 75 years, and an estimated average remaining life of approximately 30
years.

     Year 2000 Systems Modifications.  Certain computer program software has
been written using two digits rather than four digits to define the applicable
year. If left uncorrected, a system failure or miscalculations causing
disruptions of operations could result. We have implemented a formal plan
requiring programming modifications intended to ensure our systems will operate
properly in the year 2000 ("Year 2000"). This plan includes four phases
consisting of awareness, assessment and renovation, validation and
implementation. In our opinion, the scope of the Year 2000 systems modifications
is not extensive and the costs associated with addressing them are not expected
to exceed $500,000 which is primarily attributable to the completion of the BFI
information systems replacement and remediation work. No other information
technology projects have been deferred due to Year 2000 efforts.

          AWARENESS.  Our senior management approves and our Board of Directors
     evaluates and reviews as deemed necessary all Year 2000 projects if they
     are expected to result in material cost.

          ASSESSMENT AND RENOVATION.  The assessment and renovation phase of the
     plan includes both information technology-related systems and
     non-information technology areas.

             Information technology-related systems.  To date, we have assessed
        all information technology-related systems, which includes hardware,
        applications software, operating systems and databases. Our core
        business systems, including general ledger, accounts payable, fixed
        assets, customer billing and operations support function properly with
        respect to dates in the year 2000.

                                       32
<PAGE>   34

             Non-information technology areas.  Our assessment of Year 2000
        issues includes non-information technology areas such as embedded
        technology in equipment and tele-communications. We have completed an
        initial assessment of non-information technology systems and are making
        the necessary modifications. We will continue to review the
        non-information technology areas, but do not anticipate that there will
        be material impact.

          VALIDATION.  Validation includes testing and verifying the
     performance, functionality, and integration of the customer billing and
     operations support systems. After we made the Year 2000 modifications in
     the first quarter of 1999, we completed the validation phase. Additionally,
     the validation phase for the BFI systems was completed in the second
     quarter of 1999.

          IMPLEMENTATION.  Implementation of our plan includes both information
     technology-related systems and non-information technology areas.

             Information technology-related systems.  We completed the
        implementation of all modified information systems and vendor supplied
        Local Area Network ("LAN") applications. The implementation phase of the
        LAN operating-systems patches was completed in the third quarter of
        1999.

             Non-Information technology areas.  We plan to modify or remediate
        non-information technology equipment and communications hardware and
        software if the results of assessments indicate a significant risk
        exists to our business activities. We expect to make any required
        modifications through the fourth quarter of 1999. In addition, we expect
        to establish contingency plans in case of unanticipated failures, and
        update existing disaster recovery plans before 2000.

     Upon completion of our Year 2000 plan, we expect to be Year 2000 compliant
and expect to have no material exposure with respect to our information
technology-related systems. However, if we do not complete our plan in a timely
manner or the level of timely compliance by our suppliers or vendors is not
sufficient, we believe that the most likely reasonable worst-case scenario would
involve the failure of one or our critical systems. This could result in a delay
or disruption in customer service and billing. As a consequence, we could lose
customers, which would result in a loss of our revenue. We could also experience
an increase in our operating costs. In response to this scenario, we expect to
implement contingency and business continuation plans, which address our
information and non-information technology related systems. These plans include
the manual performance of processes that are currently automated.

     Based on the nature of the waste management services and the decentralized
manner in which we operate, we do not consider any one vendor or customer to be
individually significant as we obtain services and goods at each individual
location and serve over 9.9 million customers. For services obtained from
outside vendors on a company-wide basis, such as payroll processing and
financial services, we have relied upon certification of Year 2000 compliance
received directly from these vendors. However, we cannot assure that the
information systems of vendors and customers on which we rely will be Year 2000
compliant in a timely manner and will not have material and adverse effect on
our business, financial condition, results of operations and cash flow. We have
not obtained independent verification or validation to assure our reliability
and the reliability of our vendors' or customer information systems for the
potential risks and associated costs as they relate to the Year 2000 issue.

     We continue to pursue our acquisition strategy. During the acquisition
process, we evaluate companies as to their Year 2000 compliance. We are placing
priority on integrating the acquired companies and expect all non-Year 2000
compliant entities to be on compliant software by December 31, 1999.

</TABLE>

     Revenues.  Revenues in 1999 were $1,085.6 million compared to $415.7
million in 1998, an increase of 161.1%. The increase in revenues attributable to
existing operations ("Internal Growth") is estimated to be 6%. The additional
revenue growth is attributable to companies acquired, net of revenues sold,
subsequent to the end of the same period in the prior year, the most significant
of which was the acquisition of BFI on July 30, 1999.

     Cost of operations.  Cost of operations in 1999 was $635.7 million compared
to $235.2 million in 1998, an increase of 170.3%. The increase in cost of
operations was attributable to the increase in revenues described above
including acquisitions. As a percentage of revenues, cost of operations
increased to 58.6% in 1999 from 56.6% in 1998 primarily due to the operational
combination of Allied and BFI and the timing of the realization of expected
operation cost savings from the acquisition.

     Selling, general and administrative expenses.  SG&A expenses in 1999 were
$73.3 million compared to $41.5 million in 1998, an increase of 76.6%. As a
percentage of revenues, SG&A expenses decreased to 6.8% in 1999 compared to
10.0% in 1998. The 1998 SG&A expenses increase from the previously reported
amount is due to the historical restatements for companies acquired subsequent
to September 30, 1998 and accounted for using the pooling-of-interests method
for business combinations. These restated periods do not include the realization
of anticipated cost savings related to the acquired businesses. The 1999 SG&A
expenses as a percent of revenues decreased due to cost savings achieved from
the integration of businesses acquired. Significant SG&A cost savings associated
with the acquisition of BFI were achieved resulting from duplicative
administrative and sales costs which were eliminated immediately. Additionally,
the decrease in SG&A expenses as a percentage of revenues can be attributed to
the substantial overhead cost leverage through the combination of Allied and
BFI.

     Depreciation and amortization. Depreciation and amortization in 1999 was
$126.0 million compared to $48.5 million in 1998, an increase of 159.7%. The
increase in depreciation and amortization was due to an increase in goodwill of
approximately $7.1 billion, predominately from the acquisition of BFI.
Depreciation

and amortization as a percentage of revenue remained flat between periods due to
a significant increase in goodwill amortization as a percentage of revenues
offset by a decrease in the depreciation of fixed assets as a percentage of
revenues resulting from increased leverage on operating assets and the fair
market valuation of BFI assets in purchase accounting.

     Acquisition related and unusual costs.  During the third quarter of 1998,
we recorded a $29.3 million acquisition related and non-recurring charge for
transaction and integration costs associated primarily with acquisitions
accounted for as poolings-of-interest. These charges consisted of transaction
and deal costs, employee severance and transition costs, environmental related
matters, litigation liabilities, regulatory compliance matters, restructuring
and abandonment costs and loss contract provisions.

     During the three months ended September 30, 1999, the Company recorded
$548.7 million of acquisition related and unusual costs associated with the $9.6
billion acquisition of BFI, which was accounted for as a purchase. (See Note 2.)
The costs primarily relate to environmental related matters, litigation
liabilities, risk management liabilities, loss contract provisions, transition
costs, the write-off of deferred costs relating to the acquisition and a $31.8
million impairment loss to reduce the carrying value of assets held for sale.
These costs are comprised of the following:

          The Company recorded a charge of approximately $265 million related to
     changes in estimates of environmental liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations were performed by third
     party and in-house engineers. Based on these assessments, the Company made
     changes in accounting estimates of approximately (i) $136 million
     associated with the Superfund accrual for over 150 CERCLA cases in which
     BFI is involved, (ii) $28 million associated with the remedial accrual for
     six sites in which BFI is involved with remedial action plans, (iii) $56
     million associated with the environmental accrual for various containment
     and treatment matters at 76 active or closed BFI landfills and (iv) $45
     million associated with the accrual for the remedial and closure
     requirements of four BFI hazardous waste facilities.

          Management believes the environmental accrual as of September 30, 1999
     represents the most probable outcome of these matters. The Company does not
     expect that adjustments to these estimates, which are reasonably possible
     in the near term and that may result in changes to recorded amounts will
     have a material effect on the Company's consolidated liquidity, financial
     position or results of operations. As of September 30, 1999, the Company
     believes that it is reasonably possible that the ultimate outcome of the
     environmental matters could result in approximately $33 million of
     additional liability.

          The Company recorded a charge of approximately $93 million related to
     changes in estimates of litigation liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations and outstanding litigation
     were performed by third party and in-house legal counsel. The Company
     evaluated over 150 cases involving employee-related matters, insurance
     related matters, regulatory matters, collection matters and contract
     disputes. Accordingly, Allied increased the litigation accrual based on the
     most probable loss to be incurred.

          Management believes the litigation accrual as of September 30, 1999
     represents the most probable outcome of outstanding assessments, claims and
     cases. The Company does not expect that adjustments to estimates, which are
     reasonably possible in the near term and that may result in changes to
     recorded amounts will have a material effect on the Company's consolidated
     liquidity, financial position or results of operations. As of September 30,
     1999, the Company believes that it is reasonably possible that the ultimate
     outcome of the litigation matters could result in approximately $10 million
     of additional liability.

          The Company recorded an increase of approximately $20 million to the
     self-insurance or risk management accruals based on the results of a third
     party actuarial review performed in connection with due diligence and
     integration of the BFI acquisition.

          In connection with the integration of the BFI acquisition, the Company
     reviewed the existing contracts of the business for recoverability. Several
     contracts were identified which were in a loss position when the direct
     costs (excluding any non-variable type costs) attributable to the contract
     were deducted
                                       35
<PAGE>   37

     from the revenue to be generated by the contract. Consistent with Allied's
     accounting policies, the Company recorded a charge of approximately $35
     million to operations for the excess of costs over revenues of the
     identified contracts.

          As a result of the acquisition of BFI in the third quarter 1999,
     management reassessed the level of acquisitions that it would pursue in the
     future and decided that certain companies that were being targeted will no
     longer be pursued. Accordingly, the company wrote off $26 million of
     deferred charges previously incurred in connection with these potential
     acquisitions. Additionally, the Company wrote off $34 million of commitment
     fees paid in connection with a portion of the financing of the BFI
     acquisition. These fees were associated with funds that were not ultimately
     drawn due to alternative sources of financing becoming available. However,
     as secured financing for the entire purchase price of the acquisition was a
     condition of the signing of the merger agreement with BFI and the debt
     associated with these fees was not incurred, the cost was written off in
     the third quarter.

          In connection with the integration plan for BFI, Allied identified and
     notified approximately 1,500 employees that they would be retained for a
     specified period, generally not exceeding nine months from the acquisition
     date, to perform transition related functions. Subsequent to the specified
     time period, they will be terminated. Additionally, Allied identified
     certain offices and operations which are duplicative and is in the process
     of consolidating these operations. As these transition costs are not
     accruable until committed or paid, approximately $35 million of transition
     costs were expensed during the third quarter. Additionally, the Company
     accrued approximately $9 million of committed transition costs during the
     third quarter. The Company estimates that it may incur approximately $200
     million of additional transition expenses associated with the integration
     of BFI over the subsequent quarters.

          Any subsequent changes in estimates of acquisition related and unusual
     costs will be included in the acquisition related and unusual costs caption
     of the statement of operations in the period in which the change in
     estimate is made. To date, no significant changes in estimates have been
     made related to these costs.

       Equity in Earnings of Unconsolidated Affiliates.  Equity in earnings of
unconsolidated affiliates was $11.3 million for the quarter ended September 30,
1999. The amount relates to the Company's equity in the earnings of American
Ref-Fuel that was acquired in connection with the BFI acquisition on July 30,
1999. There were no investments in unconsolidated affiliates prior to the BFI
acquisition.

     Interest expense, net.  Interest expense, net was $147.0 million in 1999
compared to $19.3 million in 1998, an increase of 661.7%. Interest expense
increased due to the addition of $9.6 billion of debt related to the
acquisitions of BFI. Additionally, capitalized interest decreased to $7.9
million in 1999 compared to $16.1 million in 1998 due to the Company's change in
accounting principle related to capitalized interest in 1999 (See Note 1). The
increase in interest expense compared to early 1999 and 1998 is also due to the
substantial increase in leverage resulting from the debt financing of the BFI
acquisition causing an increase in interest costs.

     Income tax expense (benefit).  Income tax expense reflects a (23.4)%
effective income tax rate in 1999 and 55.7% in 1998. The increased rate in 1998
was primarily caused by the income tax accounting effects of applying the
pooling-of-interests method of accounting for business combinations (including
the initial recording of deferred income taxes and non-deductible transaction
costs, partially offset by the absence of income taxes on S-Corporation
pre-combination earnings). The third quarter 1999 effective tax rate deviates
from the federal statutory rate of (35%) primarily due to state income taxes,
and the effects of differences in the treatment of goodwill for book and tax
purposes including the goodwill generated from the acquisition of BFI which is
not deductible for income tax purposes.

     Extraordinary loss, net.  In July 1999, the Company replaced its credit
facility and recognized an extraordinary charge of approximately $5.3 million
($3.2 million net of income tax benefit) related to the write-off of previously
deferred debt issuance costs.

     Preferred dividends.  In connection with the BFI acquisition, the Company's
Board of Directors adopted a resolution creating a series of 1,000,000 shares of
preferred stock having a par value of $0.10 per share. These
                                       36
<PAGE>   38

shares were designated as Series A Senior Convertible Preferred Stock
("Preferred Stock") and are entitled to vote on, among other things, all matters
on which the holders of Common Stock are entitled to vote. Each share of
Preferred Stock has the number of votes equal to the number of shares of Common
Stock then issuable upon conversion, assuming shareholder approval is obtained
to permit conversion of the Preferred Stock into Common Stock ("Stockholder
Approval"). Assuming Stockholder Approval is received prior to January 30, 2000,
shares of Preferred Stock will be entitled to cumulative quarterly dividends in
an amount equal to 6.5% per annum of the sum of liquidation preference plus
accrued but unpaid dividends for prior quarters. If dividends are not paid in
cash, the liquidation preference of the Preferred Stock increases by any accrued
and unpaid dividends.

     The Preferred Stock has a redemption price of $1,000 per share, together
with any accrued and unpaid dividends. Redemption of the Preferred Stock is at
the option of the Company in whole but not in part if Stockholder Approval is
obtained prior thereto, at any time on or after July 30, 2004. After July 30,
2002, the Company has the right to redeem the Preferred Stock in whole, but not
in part, at the redemption price only if the current market price exceeds $27
per share.

     If Stockholder Approval is obtained, the Preferred Shareholders will have
the right to convert each share of Preferred Stock into the number of shares of
Common Stock obtained by dividing the redemption price plus any accrued and
unpaid dividends on the conversion date by the conversion price of $18 per
share, subject to customary anti-dilution adjustments. Upon a change in control,
Allied is required to make an offer to purchase for cash all shares of Preferred
Stock at 101% of liquidation preference plus accrued but unpaid dividends.

     As of September 30, 1999, the dividends accrued and unpaid on the Preferred
Stock are approximately $11.1 million or $11,119 per share.

</TABLE>

     Revenues.  Revenues in 1999 were $1,957.0 million compared to $1,168.5
million in 1998, and increase of 67.5%. The increase in revenues attributable to
Internal Growth is estimated to be 6%. The additional

                                       37
<PAGE>   39

revenue growth is attributable to companies acquired, net of revenues sold,
subsequent to the end of the same period in the prior year, the most significant
of which was the acquisition of BFI on July 30, 1999.

     Cost of operations.  Cost of operations in 1999 was $1,122.7 million
compared to $663.8 million in 1998, an increase of 69.1%. The increase in cost
of operations was attributable to the increase in revenues described above
including acquisitions. As a percentage of revenues, cost of operations
increased to 57.4% in 1999 from 56.8% in 1998 primarily due to the operational
combination of Allied and BFI and the timing of the realization of the operation
cost savings from the acquisition.

     Selling, general and administrative expenses.  SG&A expenses in 1999 were
$140.8 million compared to $122.1 million in 1998, an increase of 15.3%. As a
percentage of revenues, SG&A expenses decreased to 7.2% in 1999 compared to
10.5% in 1998. The 1998 SG&A expenses increase from the previously reported
amount is due to the historical restatements for companies acquired subsequent
to September 30, 1998 and accounted for using the pooling-of-interests method
for business combinations. These restated periods do not include the realization
of anticipated cost savings related to the acquired businesses. The 1999 SG&A
expenses as a percent of revenues decreased due to cost savings achieved from
the integration of businesses acquired. Significant SG&A cost savings associated
with the acquisition of BFI were able to be realized quickly due to the
duplicative administrative and sales costs which were able to be absorbed or
eliminated immediately. Additionally, the decrease in SG&A expenses as a
percentage of revenues can be attributed to the substantial increase in
revenues.

     Depreciation and amortization.  Depreciation and amortization in 1999 was
$226.4 million compared to $135.7 million in 1998, an increase of 66.8%. The
increase in depreciation and amortization was due to an increase in goodwill of
approximately $7.1 billion, predominantly from the acquisition of BFI.

ACQUISITION RELATED AND UNUSUAL COSTS

1999

     During the first nine months of 1999, the Company recorded $549.8 million
of acquisition related and unusual costs associated with the $9.6 billion
acquisition of BFI, which was accounted for as a purchase. (See Note 2.) The
costs primarily relate to environmental related matters, litigation liabilities,
risk management liabilities, loss contract provisions, transition costs, the
write-off of deferred costs relating to the acquisition and a $31.8 million
impairment loss to reduce the carrying value of assets held for sale. These
costs are comprised of the following:

          The Company recorded a charge of approximately $265 million related to
     changes in estimates of environmental liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations were performed by third
     party and in-house engineers. Based on these assessments, the Company made
     changes in accounting estimates of approximately (i) $136 million
     associated with the Superfund accrual for over 150 CERCLA cases in which
     BFI is involved, (ii) $28 million associated with the remedial accrual for
     six sites in which BFI is involved with remedial action plans, (iii) $56
     million associated with the environmental accrual for various containment
     and treatment matters at 76 active or closed BFI landfills and (iv) $45
     million associated with the accrual for the remedial and closure
     requirements of four BFI hazardous waste facilities.

          Management believes the environmental accrual as of September 30, 1999
     represents the most probable outcome of these matters. The Company does not
     expect that adjustments to these estimates, which are reasonably possible
     in the near term and that may result in changes to recorded amounts will
     have a material effect on the Company's consolidated liquidity, financial
     position or results of operations. As of September 30, 1999, the Company
     believes that it is reasonably possible that the ultimate outcome of the
     environmental matters could result in approximately $33 million of
     additional liability.

          The Company recorded a charge of approximately $93 million related to
     changes in estimates of litigation liabilities associated with BFI's
     operations. In connection with the Company's due diligence and integration
     process, assessments of the acquired operations and outstanding litigation
     were performed by

                                       38
<PAGE>   40

     third party and in-house legal counsel. The Company evaluated over 150
     cases involving employee-related matters, insurance related matters,
     regulatory matters, collection matters and contract disputes. Accordingly,
     Allied increased the litigation accrual based on the most probable loss to
     be incurred.

          Management believes the litigation accrual as of September 30, 1999
     represents the most probable outcome of outstanding assessments, claims and
     cases. The Company does not expect that adjustments to estimates, which are
     reasonably possible in the near term and that may result in changes to
     recorded amounts will have a material effect on the Company's consolidated
     liquidity, financial position or results of operations. As of September 30,
     1999, the Company believes that it is reasonably possible that the ultimate
     outcome of the litigation matters could result in approximately $10 million
     of additional liability.

          The Company recorded an increase of approximately $20 million to the
     self-insurance or risk management accruals based on the results of a third
     party actuarial review performed in connection with due diligence and
     integration of the BFI acquisition.

          In connection with the integration of the BFI acquisition, the Company
     reviewed the existing contracts of the business for recoverability. Several
     contracts were identified which were in a loss position when the direct
     costs (excluding any non-variable type costs) attributable to the contract
     were deducted from the revenue to be generated by the contract. Consistent
     with Allied's accounting policies, the Company recorded a charge of
     approximately $35 million to operations for the excess of costs over
     revenues of the identified contracts.

          As a result of the acquisition of BFI in the third quarter 1999,
     management reassessed the level of acquisitions that it would pursue in the
     future and decided that certain companies that were being targeted will no
     longer be pursued. Accordingly, the company wrote off $26 million of
     deferred charges previously incurred in connection with these potential
     acquisitions. Additionally, the Company wrote off $34 million of commitment
     fees paid in connection with a portion of the financing of the BFI
     acquisition. These fees were associated with funds that were not ultimately
     drawn due to alternative sources of financing becoming available. However,
     as secured financing for the entire purchase price of the acquisition was a
     condition of the signing of the merger agreement with BFI and the debt
     associated with these fees was not incurred, the cost was written off in
     the third quarter.

          In connection with the integration plan for BFI, Allied identified and
     notified approximately 1,500 employees that they would be retained for a
     specified period, generally not exceeding nine months from the acquisition
     date, to perform transition related functions. Subsequent to the specified
     time period, they will be terminated. Additionally, Allied identified
     certain offices and operations which are duplicative and is in the process
     of consolidating these operations. As these transition costs are not
     accruable until committed or paid, approximately $35 million of transition
     costs were expensed during the third quarter. Additionally, the Company
     accrued approximately $9 million of committed transition costs during the
     third quarter. The Company estimates that it may incur approximately $200
     million of additional transition expenses associated with the integration
     of BFI over the subsequent quarters.

          Any subsequent changes in estimates of acquisition related and unusual
     costs will be included in the acquisition related and unusual costs caption
     of the statement of operations in the period in which the change in
     estimate is made. To date, no significant changes in estimates have been
     made related to these costs.

1998

     During the year ended December 31, 1998, the Company recorded acquisition
related and unusual costs in the amount of $247.9 million. These costs consist
of transaction and deal costs, employee severance and transition costs,
environmental related matters, litigation liabilities, regulatory compliance
matters, restructuring and abandonment costs and loss contract provisions. The
Company does not anticipate that future costs to be incurred in connection with
the 1998 acquisitions will be significant as restructuring and transition
activities associated with these acquisitions had been substantially completed
as of December 31, 1998. The 1998

                                       39
<PAGE>   41

acquisition related and unusual costs discussed below predominantly relate to
acquisitions accounted for as poolings-of-interests and consist of the
following:

          Direct transaction and deal costs of $51.2 million including
     investment banker, attorney, accountant, environmental assessment and other
     third-party fees. Approximately $11.7 million was accrued at December 31,
     1998 and was paid in the first six months of 1999.

          Employee severance and transition costs of $73.6 million consist of
     $39.3 million in termination payments made to employees of acquired
     companies based on change of control provisions in preexisting contracts
     and $34.3 million of costs associated with severance payments under exit or
     integration plans implemented in connection with acquisitions made during
     1998. Exit plans primarily related to the elimination of duplicate
     corporate and administrative offices of companies acquired. Integration
     plans included the combination of field activities for human resource,
     accounting, facility maintenance, health and safety compliance and customer
     service activities of companies acquired with field activities similar to
     those of the Company. The exit and integration plans called for the
     termination of approximately 800 employees who performed managerial, sales,
     administrative support, maintenance and repair, or hauling and landfill
     operations duties. All employees were identified and notified of their
     severance or transition benefits at the time management approved the plan,
     which occurred at or around the time of the acquisitions. Approximately
     $10.1 million was accrued at December 31, 1998, the majority of which has
     been paid in 1999.

          Environmental related matters, litigation liabilities and regulatory
     compliance matters assumed in acquisitions totaled $73.4 million.
     Subsequent to the acquisitions, the Company made certain changes in
     accounting estimates due to events and new information becoming available
     for environmental liabilities of approximately $41.1 million, litigation
     liabilities of approximately $20.8 million and regulatory compliance
     liabilities of approximately $11.5 million.

     As part of the Company's acquisition due diligence process, environmental
assessments were performed at the time of acquisition by third-party and
in-house engineers. The assessments were performed at over 150 operating sites
owned or used by the 54 companies acquired by Allied in 1998. Additional
environmental liabilities were accrued based on the results of the assessments
and represent the most probable outcome of these identified contingent matters.
$27.1 million of the additional accrued environmental liability was comprised of
required remedial activities identified at 28 separate locations. These
locations include eight landfills acquired by Allied, 15 landfills not owned by
Allied, but used for disposal by collection companies acquired, and transfer
stations and maintenance facilities acquired. Required remedial activities
include the removal and treatment of waste improperly disposed of, containment
and abatement of landfill gas migration, removal and disposal of contaminated
soil and hazardous waste and legal and administrative costs of the settlement of
Superfund claims. The additional $14 million of environmental accruals related
to removal and treatment of leachate at landfills, the level of which exceeded
permitted amounts at seven of the acquired landfills. At December 31, 1998,
approximately $41.1 million and $15.8 million was accrued for environmental
matters and legal and regulatory compliance matters, respectively, which are
expected to be disbursed in future periods.

     The change in estimate relating to litigation and regulatory compliance
liabilities was accrued based on legal due diligence performed by in-house and
outside legal counsel for acquired companies at the time of acquisition and the
determination of the most probable loss incurred. As a result of this legal due
diligence, the Company identified 14 companies acquired in business combinations
accounted for as poolings-of-interest which had an aggregate of 54 asserted and
unasserted claims involving matters such as contract disputes, employment
related disputes, real and personal property and sales tax issues and billing
disputes. Additionally, the Company identified regulatory compliance issues
related to 12 companies acquired, which included citations for certain state and
federal health, safety and transportation violations and the associated costs of
fines, assessments and required maintenance costs to bring facilities and
equipment into compliance.

     Management believes the accrual as of December 31, 1998 for legal and
regulatory compliance matters represents the most probable outcome of
outstanding assessments and claims. The Company does not expect that adjustments
to estimates related to the 1998 acquisitions will have a material effect on the
Company's
                                       40
<PAGE>   42

consolidated liquidity, financial positions or results of operations. At
December 31, 1998, the Company believes that it is reasonably possible that the
ultimate outcome of the legal and regulatory compliance matters could result in
approximately $5 million of additional liability.

     Restructuring and abandonment costs were $42.1 million in business
combinations accounted for as pooling-of-interests. Costs to relocate redundant
operations and to transition them to common information systems were $23.1
million. Redundant operations consisted primarily of activities for human
resources, accounting, facility maintenance, health and safety compliance and
customer service which were performed in field offices of companies acquired.
Abandonment costs and losses on the disposal of duplicate revenue producing
assets relating to specifically identified transfer stations and recycling
facilities were $8.8 million. Revenue and net operating income of the abandoned
operations represented less than one percent of the Company's consolidated
amounts. Additionally, $10.2 million of costs were incurred for the disposition
of redundant non-revenue producing assets. This includes $7.6 million that was
accrued at December 31, 1998 in accordance with exit and integration plans and
is expected to be paid in 1999. This accrual is for payments under
non-cancelable lease agreements for corporate offices to be vacated and other
costs to close corporate facilities after operations have ceased under exit
plans implemented during 1998 at five companies acquired.

     Loss contract provisions were $7.6 million for losses associated with
collection contracts and other contractual obligations assumed in acquisitions.
Approximately $5 million was accrued at December 31, 1998 and was paid as of
September 30, 1999.

     Any subsequent changes in estimates of acquisition related and unusual
costs will be included in the acquisition related and unusual costs caption of
the statement of operations in the period in which the change in estimate is
made. To date, no significant changes in estimates have been made related to
these costs. During the first nine months of 1999, the Company expensed
approximately $0.3 million in transition salaries relating to plans implemented
in 1998.

     Equity in Earnings of Unconsolidated Affiliates.  Equity in earnings of
unconsolidated affiliates was $11.3 million for the nine months ended September
30, 1999. The amount relates to the Company's equity in the earnings of American
Ref-Fuel that was acquired in connection with the BFI acquisition on July 30,
1999. There were no investments in unconsolidated affiliates prior to the BFI
acquisition.

     Interest expense, net.  Interest expense, net was $227.3 million in 1999
compared to $61.4 million in 1998, an increase of 270.2%. Interest expense
increased due to the addition of $9.6 billion of debt related due primarily to
the acquisition of BFI. Additionally, capitalized interest decreased to $15.0
million in 1999 compared to $47.2 million in 1998 due to the Company's change in
accounting principle related to capitalized interest in 1999. (See Note 1). The
increase in interest expense compared to early 1999 and 1998 is also due to the
substantial increase in leverage resulting from the debt financing of the BFI
acquisition causing an increase in interest costs.

     Income tax expense (benefit).  Income tax expense reflects a (15.5)%
effective income tax rate in 1999 and 50.6% in 1998. The increased rate in 1998
was primarily caused by the income tax accounting effects of applying the
pooling-of-interests method of accounting for business combinations (including
the initial recording of deferred income taxes and non-deductible transaction
costs, partially offset by the absence of income taxes on S-Corporation
pre-combination earnings). The effective tax rate for the first nine months of
1999 deviates from the federal statutory rate of (35%) primarily due to state
income taxes and the effects of differences in the treatment of goodwill for
book and tax purposes including the goodwill generated from the acquisition of
BFI which is not deductible for income tax purposes.

     Extraordinary loss, net.  In June 1998, the Company replaced its credit
facility and recognized an extraordinary charge of approximately $5.1 million
($3.1 million net of income tax benefit) related to the write-off of previously
deferred debt issuance costs.

     In July 1999, the Company replaced its credit facility and recognized an
extraordinary charge of approximately $5.3 million ($3.2 million net of income
tax benefit) related to the write-off of previously deferred debt issuance
costs.

                                       41
<PAGE>   43

     Cumulative effect of change in accounting principle, net.  In connection
with the acquisition of BFI, management changed the capitalized interest policy
of the Company to more accurately reflect the Company's long-term business
strategy. As a result, the Company recorded a charge of $64.3 million, net of
related tax, during the quarter ended September 30, 1999, to reflect the
cumulative effect on prior years of the change in the method of interest
capitalization. There were no changes in accounting principle recorded during
1998.

     Preferred dividends.  In connection with the BFI acquisition, the Company's
Board of Directors adopted a resolution creating a series of 1,000,000 shares of
preferred stock having a par value of $0.10 per share. These shares were
designated as Series A Senior Convertible Preferred Stock ("Preferred Stock")
and are entitled to vote on, among other things, all matters on which the
holders of Common Stock are entitled to vote. Each share of Preferred Stock has
the number of votes equal to the number of shares of Common Stock then issuable
upon conversion, assuming shareholder approval is obtained to permit conversion
of the Preferred Stock into Common Stock ("Stockholder Approval"). Assuming
Stockholder Approval is received prior to January 30, 2000, shares of Preferred
Stock will be entitled to cumulative quarterly dividends in an amount equal to
6.5% per annum of the sum of liquidation preference plus accrued but unpaid
dividends for prior quarters. If dividends are not paid in cash, the liquidation
preference of the Preferred Stock increases by any accrued and unpaid dividends.

     The Preferred Stock has a redemption price of $1,000 per share, together
with any accrued and unpaid dividends. Redemption of the Preferred Stock is at
the option of the Company in whole but not in part if Stockholder Approval is
obtained prior thereto, at any time on or after July 30, 2004. After July 30,
2002, the Company has the right to redeem the Preferred Stock in whole, but not
in part, at the redemption price only if the current market price exceeds $27
per share.

     If Stockholder Approval is obtained, the Preferred Shareholders will have
the right to convert each share of Preferred Stock into the number of shares of
Common Stock obtained by dividing the redemption price plus any accrued and
unpaid dividends on the conversion date by the conversion price of $18 per
share, subject to customary anti-dilution adjustments. Upon a change in control,
Allied is required to make an offer to purchase for cash all shares of Preferred
Stock at 101% of liquidation preference plus accrued but unpaid dividends.

     As of September 30, 1999, the dividends accrued and unpaid on the Preferred
Stock are approximately $11.1 million or $11,119 per share.

LIQUIDITY AND CAPITAL RESOURCES

     Historically, we have satisfied our acquisition, capital expenditure and
working capital needs primarily through bank financing and public offerings and
private placements of debt and equity securities. Between January 1992 and
September 30, 1999, we completed debt financings in excess of $14.3 billion.

     Due to acquisitions and the capital requirements of our business strategy,
we have used amounts in excess of the cash generated from operations to fund
acquisitions and capital expenditures. In the future we anticipate that cash
flow from operations, less acquisitions and capital requirements, will be
sufficient to repay our long and short-term debt. However, over the next several
quarters, transition and integration costs associated with the BFI acquisition
may cause us to have a negative cash flow from operations, less acquisitions and
capital requirements, or may cause us to incur additional amounts of debt. In
connection with acquisitions, we have assumed or incurred indebtedness with
relatively short-term repayment schedules, thereby increasing our current and
medium-term liabilities. Also, for certain acquisitions, current liabilities are
recorded for acquisition related and unusual costs that require payment in the
near term. Current liabilities periodically include scheduled payments required
under our Bank Credit Facility. In addition, we have acquired operating
equipment using financing leases, which have short, and medium-term maturities.
Also we use excess cash generated from operations to pay down amounts owed on
our revolving line of credit which is classified as long-term debt. As a result,
we periodically have low levels of working capital or working capital deficits.

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

(1) Consists principally of provisions for depreciation and amortization,
    doubtful accounts, potentially unrealizable acquisition costs, deferred
    income taxes and undistributed earnings of equity investment.

     As of September 30, 1999, we had cash and cash equivalents of $101.6
million. Our capital expenditure and working capital requirements have increased
significantly, reflecting our rapid growth by acquisition and development of
revenue producing assets, and will increase further compared to the nine months
ended September 30, 1998 and 1999 due to the acquisition of BFI. During the nine
months ended September 30, 1999, we acquired solid waste operations, excluding
the BFI acquisition, representing approximately $378.6 million in annual
revenues ($332.0 million net of intercompany eliminations), and sold operations
representing approximately $116.0 million in annual revenue. Net consideration
of approximately $463.4 million comprised of cash, notes and common stock was
paid in these transactions. For the calendar year 1999, we expect to spend
approximately $450 million for capital expenditures, closure and post-closure,
and remediation expenditures relating to our landfill operations. As we continue
to acquire waste operations in 1999, additional capital amounts will be required
during 1999 for the acquisition of businesses and the capital expenditure
requirements related to those acquired businesses.

     On September 30, 1999, our debt structure consisted primarily of $5.6
billion outstanding under the 1999 Credit Facility, $1.7 billion of the 1998
Senior Notes, $2.0 billion of the 1999 Notes and $1.3 billion of senior debt
acquired in connection with the BFI acquisition. As of September 30, 1999 there
is aggregate availability under the Revolving Credit Facility of approximately
$1.1 billion to be used for working capital, letters of credit, acquisitions and
other general corporate purposes. The indentures relating to the 1998 Senior
Notes, the 1999 Notes and the 1999 Credit Agreement contain financial and
operating covenants and restrictions on

                                       43
<PAGE>   45

our ability to complete acquisitions, pay dividends, incur indebtedness, make
investments and take certain other corporate actions. A substantial portion of
our available cash will be required to be applied to service indebtedness.
Currently, on an annualized basis, this is expected to include approximately
$662.7 million in annual principal and interest payments.

     We are also required to provide financial assurances to governmental
agencies under applicable environmental regulations relating to our landfill
operations and collection contracts. We satisfy these financial assurance
requirements by issuing performance bonds, letters of credit, insurance polices
or trust deposits as they relate to landfill closure and post-closure costs and
performance under certain collection contracts. At September 30, 1999, we had
outstanding approximately $1.4 billion in financial assurance instruments
represented by $603.8 million of performance bonds, $649.2 million of insurance
policies, $90.7 million of letters of credit and $52.0 million of trust
deposits. During 1999, we expect to be required to provide approximately $1.4
billion of financial assurance instruments relating to the Company's landfills
operations and collection contracts. We expect that financial assurance
obligations will increase in the future as we acquire and expand our landfill
activities and that a greater percentage of the financial assurance instruments
will be comprised of performance bonds and insurance policies.

     We have lease facilities (the "Lease Facilities") that allow us to enter
into equipment leases at rates ranging from similar term treasury note rates
plus 1.55% for terms of 36 to 84 months. We have equipment leases outstanding at
December 31, 1998 and September 30, 1999 of $36.6 million and $16.2 million,
respectively.

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

     Our ability to meet future capital expenditure and working capital
requirements, to make scheduled payments of principal, to pay interest, or to
refinance our indebtedness, and to fund capital amounts required for the
acquisition of businesses and the expansion of existing businesses depends on
our future performance, which, to a certain extent, is subject to general
economic, financial, competitive, legislative, regulatory and other factors
beyond our control. On the basis of historical financial information, including
recent operating history of both Allied and BFI, we believe that available cash
flow, together with available borrowings under the new credit facility, our
lease facilities and other sources of liquidity will be adequate to meet our
anticipated future requirements for working capital, letters of credit, capital
expenditures, scheduled payments of principal and interest on debt incurred
under the new credit facility, the assumed BFI debt, the 1998 Senior Notes, the
1999 Notes and the notes, and capital amounts required for acquisitions and
expansion. However, we may have to refinance the principal payment at maturity
on the 1998 Senior Notes, the 1999 Notes and the notes. We cannot assure you
that our business will generate sufficient cash flow from operations or that we
will be able to avail ourselves of future financings in an amount sufficient to
enable us to service our indebtedness or to make necessary capital expenditures,
or that any refinancing would be available on commercially reasonable terms if
at all. Further, depending on the timing, amount and structure of any future
acquisitions and the availability of funds under the new credit facility, we may
need to raise additional capital to fund the acquisition and integration of
additional solid waste businesses. We may raise such funds through additional
bank financings or public or private offerings of our debt and equity
securities. We cannot assure you that we will be able to secure such funding, if
necessary, on favorable terms, if at all. If we are not successful in securing
such funding, our ability to pursue our business strategy may be impaired and
results of operations for future periods may be negatively affected. (See Note 6
to Allied's Condensed Consolidated Financial Statements.)

SIGNIFICANT FINANCING EVENTS

     In June 1998, we repaid $486.8 million outstanding under the 1997 Credit
Agreement and entered into a new credit agreement (the "Credit Agreement"). The
Credit Agreement provides a $800 million five year senior secured revolving
credit facility (the "Revolving Credit Facility") and a $300 million five year
senior secured term loan facility (the "Term Loan Facility" and together with
the Revolving Credit Facility, the "Senior Credit Facility"). The Term Loan
Facility is a funded, amortizing senior secured term loan with annual principal
payments increasing from $75 million in 2001, to $105 million in 2002, and to
$120 million in 2003. Principal under the Revolving Credit Facility is due upon
maturity.

     In December 1998, Allied NA issued an aggregate of $1.7 billion of senior
notes consisting of $225 million 7 3/8% senior notes due 2004 (the "Five Year
Senior Notes"), $600 million 7 5/8% senior notes due 2006 (the "Seven Year
Senior Notes"), and $875 million 7 7/8% senior notes due 2009 (the "Ten Year
Senior Notes" and collectively the "1998 Senior Notes") in a Rule 144A offering
which was subsequently registered for public trading with the SEC in January,
1999. We used the net proceeds from the 1998 Senior Notes to fund the purchase
of all of the outstanding 1996 Notes and Senior Discount Notes, to repay
borrowings outstanding under the Senior Credit Facility and certain capital
lease obligations and for general corporate purposes. The Five Year Senior Notes
and Seven Year Senior Notes will be redeemable, at our option, in whole or from
time to time in part, at a redemption price equal to the greater of (i) 100% of
their principal amount or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to maturity on a
semi-annual basis at the treasury yield plus 50 basis points, plus in each case
accrued but unpaid interest to but excluding the date of redemption. The Ten
Year Senior Notes will be redeemable at our option, in whole or in part, at any
time on or after January 1, 2004 in cash at the redemption price plus accrued
and unpaid interest to but excluding the date of redemption. Prior to January 1,
2004, the Ten Year Senior Notes will be redeemable, at our option, in whole or
in part, at any time, in cash, at a redemption price equal to the greater of (i)
100% of their principal amount or (ii) the sum of the present values of the
remaining scheduled payments of principal and interest thereon discounted to
maturity on a semi-annual basis at the treasury yield plus 50 basis points, plus
accrued but unpaid interest to but excluding the date of redemption. In
addition, at any time prior to January 1, 2002, we may redeem up to 33 1/3% of
the aggregate principal amount of Ten Year Senior Notes originally issued at a
redemption price equal to 107.9% of the principal amount thereof, plus accrued
and unpaid interest to the date of redemption, with the net cash proceeds of one
or more public offerings of capital stock; provided that the notice of
redemption with respect to any such redemption is mailed within 30 days
following the closing of the corresponding public offering. The 1998 Senior
Notes will not be subject to any redemption at the option of any holder thereof
prior to the final maturity of such notes except as set forth in the applicable
indenture. We guarantee the 1998 Senior Notes and substantially all of Allied
NA's current and future subsidiaries, the guarantees of which are expressly
subordinated to the guarantees of Allied NA's Credit Agreement.

     In connection with the completion of the acquisition of BFI, we entered
into new financing arrangements and repaid all amounts borrowed under the Credit
Agreement and all amounts borrowed by BFI under its commercial paper program.
The new financing arrangements were: (i) a new credit facility (the "1999 Credit
Facility") for Allied NA, which is guaranteed by us and substantially all of our
subsidiaries (including BFI and its subsidiaries), from a bank group for $7.7
billion to provide financing for the acquisition of BFI and working capital for
us following the acquisition (ii) the sale of $2 billion of 10% Senior
Subordinated Notes due 2009 (the "1999 Notes") by Allied NA which are guaranteed
by us and substantially all of our subsidiaries (including BFI and its
subsidiaries), and (iii) the sale for $1 billion of Senior Convertible Preferred
Stock (the "Preferred Stock"). In connection with the completion of the
acquisition of BFI, we also guaranteed certain of BFI's remaining debt and, for
the 1998 Senior Notes and for certain of BFI's remaining debt, provided
collateral (pari passu with the 1999 Credit Facility) consisting of certain of
BFI's assets. Both the New Credit Facility and the 1999 Notes contain
restrictions on Allied's ability to make acquisitions, purchase fixed assets
above certain amounts, pay dividends, incur additional 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
Allied's assets. The 1999 Credit Facility, the 1999 Notes and the Preferred
Stock

                                       45

contain provisions, which could require repayment upon a defined "change of
control" of Allied and the Preferred Stock also contain restrictions on Allied's
ability to pay cash dividends on common stock.

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 report, is Forward Looking Statement. Although we believe that the
expectations reflected in such Forward Looking Statements are reasonable, we can
give no assurance that such expectations will prove to be 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,
including whether and when the acquisitions will be accretive to earnings, made
by or to be made by us, or projections involving anticipated revenues, earnings,
levels of capital expenditures or other aspects of operating results and the
underlying assumptions including Internal Growth as well as general economic and
financial market conditions. All phases of our operations are subject to a
number of uncertainties, risks and other influences, many of which are outside
of our control and any one of which, or a combination of which, could materially
affect the results of our operations and whether Forward Looking Statements made
by us ultimately prove to be accurate. Such important factors ("Important
Factors") that could cause actual results to differ materially from our
expectations are disclosed in this section and elsewhere in this report. All
subsequent written and oral Forward Looking Statements attributable to us or
persons acting on our behalf are expressly qualified in their entirety by the
Important Factors described below that could cause actual results to differ from
our expectations. Shareholders, potential investors and other readers are urged
to consider these factors in evaluating Forward Looking Statements and are
cautioned not to place undue reliance on these Forward Looking Statements. The
forward looking statements made herein are only made as of the date of this
filing and we undertake no obligation to publicly update such forward-looking
statements to reflect subsequent events or circumstances.

     Competition.  The solid waste collection and disposal business is highly
competitive and requires substantial amounts of capital. We compete with
numerous waste management companies, some of which have significantly larger
operations and greater resources. We also compete with those counties and
municipalities that maintain their own waste collection and disposal operations.
Forward Looking Statements assume that we will be able to effectively compete
with the other waste management companies and municipalities and that we will be
able to maintain or improve margins (or pricing of services) on existing or
acquired operations and effectively compete with government owned and operated
landfills which enjoy certain competitive advantages from tax-exempt financing
and tax revenue subsidies.

     Availability of Acquisition Targets.  Our ongoing acquisition program is a
key element of our expansion strategy and our ability to implement our vertical
integration strategy in a successful manner. In addition, obtaining landfill
permits has become increasingly difficult, time consuming and expensive. We
cannot assure that we will succeed in obtaining landfill permits or locating
appropriate acquisition candidates that can be acquired at price levels that we
consider appropriate and that reflect historical prices. The Forward Looking
Statements assume that a number of acquisition candidates and landfill
properties sufficient to meet our goals will be available for purchase and that
we will be able to complete the acquisitions at prices that we have experienced
in the past two years.

     Divestitures.  Our Forward Looking Statements assume that we will be able
to exit certain regional markets and sell certain non-strategic businesses.
There can be no assurance as to whether or when transactions will close or the
amounts to be received in such transactions, including transactions under
definitive agreement, and whether we will be successful in negotiating asset
sales at a pace and on terms sufficient to achieve our goals.

     Integration.  Our financial position and results of operations depend to a
large extent on the integration of recently acquired businesses including the
acquisition of BFI completed on July 30, 1999. Before the acquisition of BFI,
Allied and BFI operated as separate entities. We may not be able to maintain the
levels of

                                       46
<PAGE>   48

operating efficiency that Allied or BFI had achieved or might achieve
separately. Successful integration of BFI's operations will depend upon our
ability to manage those operations and to eliminate redundant and excess costs.
Because of difficulties in combining operations, we may not be able to achieve
the cost savings, increase in internalization rates, and other size related
benefits that we hope to achieve after the acquisition. 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 our future
results of operations.

     Ongoing Capital Requirements.  To the extent that internally generated cash
and cash available under our 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,
we will require additional equity and/or debt financing in order to provide such
cash. We have incurred significant debt obligations in the last two years, which
entail substantial debt service costs. The Forward Looking Statements assume
that we will be able to raise the capital necessary to finance such requirements
at rates that are as good as or better than those we are currently experiencing.
We cannot assure, however, that such financing and hedging and other means of
fixing interest rates on our debt will be available or, if available, that we
will find such terms regarding debt service costs and interest rates consistent
with the assumptions of Forward Looking Statements or otherwise satisfactory.
See "Liquidity and Capital Resources".

     Economic Conditions.  Our business is affected by general economic
conditions. The Forward Looking Statements assume that we will be able to
achieve internal volume and price growth, which is not impacted by an economic
downturn. As our revenue continues to grow it is likely that the rates of
internal growth will reflect growth rates, which are less than those,
experienced in 1998. We cannot assure that an economic downturn will not result
in a reduction in the volume of waste being disposed of at our operations and/or
the price that we can charge for our services.

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

     Dependence on Senior Management.  We are highly dependent upon our senior
management team. In addition, as we continue to grow, our 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
us at compensation levels that are within industry norms. We may also encounter
difficulty in the assimilation and retention of employees. 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 us.

     Influence of Government Regulation.  Our 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 our 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 us. 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 our
operations due to government regulation.

                                       47
<PAGE>   49

     Potential Environmental Liability.  We may incur liabilities for the
deterioration of the environment as a result of our operations. Any substantial
liability for environmental damage could materially adversely affect our
operating results and financial condition. Due to the limited nature of our
insurance coverage of environmental liability, if we were to incur liability for
environmental damage, our business and financial condition could be materially
adversely affected. The Forward Looking Statements assume that we 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.

     Year 2000 Systems Modifications.  We expect to be Year 2000 compliant in a
timely manner and expect to have no material exposure with respect to
information technology-related systems. With respect to non-information
technology areas, it is uncertain what risks are associated with the Year 2000
issue and any risks that may be identified could have a material, adverse effect
on our business, financial condition, and results of operations and cash flows.
We cannot assure that the systems of our customers and vendors on which we rely
will be converted in a timely manner and will not have an adverse effect on our
systems or operations. The Forward-Looking Statements assume that there will be
no material adverse effect on our systems or operations related to the Year 2000
issue.

INFLATION AND PREVAILING ECONOMIC CONDITIONS

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

SEASONALITY

     We believe that our collection, transfer 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.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The below information is provided as of December 31, 1998. We are subject
to interest rate risk on our long-term debt. Although no exposure exists with
respect to our fixed rate long-term corporate debt instruments, we run the risk
of interest rate fluctuations with respect to our LIBOR variable rate Senior
Credit Facility at December 31, 1998. To modify the risk from these interest
rate fluctuations, we enter into hedging transactions that have been authorized
pursuant to our policies and procedures. We do not use financial instruments for
trading purposes and we are not a party to any leveraged derivatives. The
following table sets forth, as of December 31, 1998, our long-term debt
obligations, principal cash flows by scheduled maturity, average interest rate
and estimated fair market value (amounts in thousands, except interest rates):

     We have effectively converted our long-term debt, which requires payment at
variable rates of interest, to fixed rate obligations through interest rate swap
transactions. These transactions require us to pay fixed rates of interest on
notional amounts of principal to counter-parties. The counter-parties, in turn,
pay to us variable rates of interest on the same notional amounts of principal.
Increases or decreases in short-term market rates would not impact earnings and
cash flow as all variable rate debt has been swapped for fixed rates. In
addition, decreases in long-term market interest rates would have the effect of
increasing the fair value of our long-term debt and other long-term, fixed rate
obligations. The following interest rate table shows the interest rate swaps
that were in effect and their fair value as of December 31, 1998:

MARKET PRICE RISK

     We have risk exposure associated with the market price on the 1998 Senior
Notes. The 1998 Senior Notes are recorded at book value, which could vary from
current market prices. At December 31, 1998, the 1998 Senior Notes had a value
of $1.7 billion based on quoted average market prices.

which have been audited by Arthur Andersen LLP, independent public accountants,
and have been restated to give effect to transactions accounted for using the
pooling-of-interests method for business combinations. See note 2 to Allied's
consolidated financial statements. The financial data presented below for the
year ended December 31, 1994 are derived from Allied's consolidated financial
statements, which have not been audited subsequent to being restated for
business combinations accounted for as poolings-of-interests completed in 1998.
The financial data for the nine months ended September 30, 1998 and 1999 have
been derived from Allied's unaudited condensed consolidated

                                      II-1

(1) Acquisition related and unusual costs primarily relate to acquisitions and
    management's changes in strategic plans and restructuring resulting from the
    acquisitions. These costs consist of transaction or deal costs, employee
    severance and transition costs, changes in estimates relating to
    environmental or legal matters, restructuring costs related to the
    consolidation or relocation of operations, costs for the abandonment or sale
    of non-revenue producing assets, and provisions for losses on contractual
    obligations.

(2) During the fourth quarter of 1998, Allied recognized asset impairment
    charges aggregating $69.7 million. These charges related to assets held for
    future use and assets disposed of in the first and second quarters

                                      II-2

of 1999. An impairment charge of $45.9 million, with no associated tax benefit
was recorded relating to goodwill of a waste transportation business recorded by
a company acquired in 1998 by Allied. Additionally, an impairment charge of
     $23.8 million was recorded for the write down to net realizable value less
     cost of disposal of assets to be sold relating to non-core or
     non-integrated operating districts.

(3) The extraordinary losses were incurred as a result of premiums paid for the
    early extinguishment of debt and the write-off of related deferred debt
    issue costs.

(4) During the third quarter of 1999, Allied changed its method of calculating
    capitalized interest and recognized the impact of this change in accounting
    principle as a cumulative charge of approximately $64.3 million, net of tax
    effective January 1, 1999.

(5) The non-cash conversion fee of $2.2 million was incurred in the fourth
    quarter of 1995 as a result of inducement offered by Allied to holders of
    certain convertible preferred stock and convertible subordinated notes to
    exercise their conversion option to receive Allied common stock. The
    inducement fee consisted of payment of dividends or interest from the
    conversion date through the first call or redemption date of each
    convertible security. Approximately 7.8 million shares of common stock were
    issued for conversion and approximately 285,000 shares were issued for the
    conversion fee.

(6) For purposes of calculating the ratio of earnings to fixed charges, earnings
    consist of pretax income without capitalized interest and fixed charges
    (exclusive of preferred stock dividends). Fixed charges include interest
    expense and capitalized interest. Earnings to fixed charges for the periods
    presented were retroactively stated for the change in accounting principle.

(7) For purposes of calculating the long-term debt to total capitalization, the
    Company included the Series A Senior Convertible Preferred Stock in equity.
    If the preferred stock were to be included in debt instead of equity, the
    debt to total capitalization percentage would be 94%.

 *  Earnings were insufficient to cover fixed charges by $65,402, $86,834 and
    $313,690 for the years ended December 31, 1996, 1998 and the nine months
    ended September 30, 1999 respectively.

Re: Form 10-Q Report for the quarter ended September 30, 1999.

Gentlemen and Ladies:

This letter is written to meet the requirements of Regulation S-K calling for a
letter from a registrant's independent accountants whenever there has been a
change in accounting principle or practice.

We have been informed that, as of January 1, 1999, Allied Waste Industries,
Inc. (the "Company") changed the method of calculating the amount of interest
to be capitalized under Statement of Financial Accounting Standard No. 34
Capitalization of Interest Cost. Previously, interest was capitalized using a
method that defined the area of a landfill under development as all acreage
considered available for development. Under the new methodology, the area of a
landfill under development is defined for accounting purposes as only the
portion of the permitted acreage currently undergoing active cell development.
With both methods, actual acquisition, permitting and construction costs
incurred related to the area under development qualify for interest
capitalization and any costs incurred related to areas already developed and
accepting waste no longer qualify for interest capitalization. The effect of
this change in definition is to substantially reduce the acreage qualifying for
interest capitalization. According to the management of the Company, the change
in method was made to more accurately reflect the new operating strategy of the
Company as a result of recent business combinations.

A complete coordinated set of financial and reporting standards for determining
the preferability of accounting principles among acceptable alternative
principles has not been established by the accounting profession. Thus, we
cannot make an objective determination of whether the change in accounting
described in the preceding paragraph is to a preferable method. However, we
have reviewed the pertinent factors, including those related to financial
reporting, in this particular case on a subjective basis, and our opinion
stated below is based on our determination made in this manner.

We are of the opinion that the Company's change in method of accounting is to
an acceptable alternative method of accounting, which, based upon the reason
stated for the change and our discussions with you, is also preferable under
the circumstances in this particular case. In arriving at this opinion, we have
relied on the business judgment and business planning of your management.

We have not audited the application of this change to the financial statements
of any period subsequent to December 31, 1998. Further, we have not examined
and do not express any opinion with respect to your financial statements for
the three and nine months ended September 30, 1999.

Very truly yours,

ARTHUR ANDERSEN LLP
