                                    May 15, 1998
     


Dear Stockholder,
    
     You are cordially invited to attend a Special Meeting of Stockholders of
American Waste Services, Inc. to be held on Monday, June 15, 1998 at the Grand
Pavilion, located at One American Way, Warren, Ohio, at 10:30 a.m., local time.
Enclosed are a Notice of Special Meeting of Stockholders and a Proxy Statement
relating to the Special Meeting.
     
    
     At the Special Meeting you will be asked to consider and vote upon two
related proposals.  One proposal is to distribute to you the Company's wholly
owned subsidiary, Avalon Holdings Corporation ("Avalon"), which will own the
Company's transportation, technical environmental services, waste disposal
brokerage and management and golf course and related operations.  The other
proposal is to merge the remainder of the Company with a wholly owned subsidiary
of USA Waste Services, Inc., which will result in the receipt by each of you of
$4.00 per share in cash.
     

    
     YOUR BOARD OF DIRECTORS BELIEVES THAT THESE PROPOSALS ARE IN THE BEST
INTERESTS OF STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE TO
APPROVE THEM.  The proposals must both be approved by the holders of the Class A
common stock and by the holders of the Class B common stock, each voting as a
separate class, in order for either transaction to take place.  ACCORDINGLY, THE
AFFIRMATIVE VOTE OF THE HOLDERS OF AT LEAST TWO-THIRDS (66-2/3 PERCENT) OF THE
OUTSTANDING SHARES OF EACH CLASS OF COMMON STOCK IS REQUIRED IN ORDER FOR THE
COMPANY'S STOCKHOLDERS TO RECEIVE $4.00 PER SHARE IN CASH AND OWNERSHIP OF
AVALON.  Holders of approximately 95 percent of the Class B common stock have
agreed, pursuant to voting agreements and irrevocable proxies, to vote in favor
of the proposals.
     
    
     The Company retained an independent appraiser to render an opinion as to
the fair market value of the capital stock of Avalon that will be outstanding
after the distribution of Avalon to the Company's stockholders to serve as a
valuation basis for establishing the amount of any taxable gain resulting from
that distribution.  The opinion of that appraiser states that, as of March 31,
1998, such fair market value is reasonably stated in the amount of approximately
$30.4 million.  Based upon the number of outstanding shares of the Company's
common stock, this is the equivalent of $1.00 per share.  Furthermore, based
upon the distribution of one share of Avalon common stock for each eight shares
of the Company's common stock, the valuation equates to $8.00 per share of
Avalon common stock.  The opinion of the appraiser should not be relied upon as
an indication of the prices at which shares of Avalon common stock may actually
trade.
     
<PAGE>
 
     Details of these proposals, which will  be considered at the Special
Meeting, as well as important information relating to them, are set forth in the
accompanying Proxy Statement and should be considered carefully.  BECAUSE OF THE
SIGNIFICANCE OF THESE TRANSACTIONS TO THE COMPANY AND ITS STOCKHOLDERS, IT IS
VITAL THAT EVERY STOCKHOLDER VOTES AT THE SPECIAL MEETING IN PERSON OR BY PROXY.

     PLEASE SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD PROMPTLY in the
accompanying envelope, which requires no postage if mailed in the United States.
You are, of course, welcome to attend the special meeting and vote in person,
even if you have previously returned your proxy card.
    
     PLEASE DO NOT THROW THESE MATERIALS AWAY.  IF YOU DO NOT SIGN AND RETURN
YOUR PROXY CARD, IT WILL BE AS IF YOU VOTED "AGAINST" THE PROPOSAL.  AGAIN,
PLEASE VOTE.
     

                                    Sincerely yours,

                                    /s/ Darrell D. Wilson

          outstanding shares of capital stock of Avalon on a pro rata and
          corresponding basis, all to be effected in accordance with the terms

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

                             CAUTIONARY STATEMENTS

     This Proxy Statement/Information Statement (this "Proxy Statement")
contains statements relating to future results of American Waste Services, Inc.
("AWS") and Avalon Holdings Corporation ("Avalon"), including certain
projections and business trends that are "forward-looking statements" as defined
in the Private Securities Litigation Reform Act of 1995.  All statements
regarding AWS's or Avalon's expected future financial positions, results of
operations, cash flows, dividends, financing plans, business strategies,
budgets, projected costs and capital expenditures, competitive positions, growth
opportunities for existing services, plans and objectives of management for
future operations and markets for stock are forward-looking statements.
Moreover, when used in this Proxy Statement with respect to AWS or Avalon, the
words "believe," "anticipate," "hope," "estimate," "project," "intend,"
"expect," and similar expressions are intended to identify forward-looking
statements.  Although AWS and Avalon believe the expectations reflected in such
forward-looking statements are based on reasonable assumptions, no assurance can
be given that such expectations will prove to have been correct.  Any forward-
looking statements contained in this Proxy Statement should not be relied upon
as predictions of future events.  Such statements are necessarily dependent on
assumptions, data or methods that may be incorrect or imprecise and may be
incapable of being realized.  Stockholders are hereby notified that such
information reflects the opinions of AWS's and Avalon's management as to the
future.  Stockholders should use their own judgment as to the significance of
this information to their individual decisions.

     With respect to Avalon, important factors that could cause actual results
to differ materially from the expectations reflected in any forward-looking
statements herein include, among other things, dependence on arrangements with
present and future customers and suppliers (including AWS), contract terms
offered by competitors, competition within each of Avalon's business segments,
and costs or difficulties relating to the establishment of Avalon as a separate
entity.

     Readers are cautioned not to place undue reliance on the forward-looking
statements contained herein, which speak only as of the date hereof.  The
information contained in this Proxy Statement is believed by AWS and Avalon to
be accurate as of the date hereof.  Changes may occur after that date, and
neither AWS nor Avalon will update that information except as required by law in
the normal course of their respective public disclosure practices.
    
     This Proxy Statement is first being mailed to stockholders of AWS on or
about May 15, 1998.

                                    SUMMARY

     The following summary is not intended to be complete and is qualified in
all respects by the more detailed information included elsewhere in this Proxy
Statement, the Appendices hereto and the documents filed as exhibits to the
Registration Statement (as hereinafter defined) of which this Proxy Statement is
a part.  Stockholders are urged to read carefully this Proxy Statement,
including the Appendices hereto, and those documents in their entirety.
References herein to "AWS" and "Avalon" include their respective subsidiaries
unless the context otherwise requires.

Special Meeting

Date, Time and Place
    
     This Proxy Statement is being furnished in connection with the solicitation
of proxies by AWS from holders of shares of its Class A common stock, no par
value ("AWS Class A Common Stock"), and its Class B common stock, no par value
("AWS Class B Common Stock" and, together with the AWS Class A Common Stock, the
"AWS Common Stock"), for use at a Special Meeting of Stockholders to be held at
the Grand Pavilion, located at One American Way, Warren, Ohio, at 10:30 a.m.,
local time, June 15, 1998 and at any adjournments thereof (the "Special
Meeting").

Matters for Consideration
     
  At the Special Meeting, the stockholders of AWS will be asked to consider and
vote upon the following two related proposals (the "Proposals"):

    
Proposal 1.  The spin-off of Avalon Holdings Corporation.  Approval of (i) the
             -------------------------------------------                      
          contribution by AWS to its wholly owned subsidiary, Avalon, of all
          businesses of AWS other than the nonhazardous solid waste landfills
          owned, the refuse collection services provided and the landfill gas
          collection and sales business conducted by certain subsidiaries of
          AWS, and (ii) a special dividend (the "Spin-off") to the holders of
          the outstanding shares of AWS Common Stock of all outstanding shares
          of capital stock of Avalon on a pro rata and corresponding basis, all
          to be effected in accordance with the terms of a Contribution and
          Distribution Agreement dated as of May 7, 1998 between Avalon and AWS
          (the "Distribution Agreement").
     
Proposal 2.  The merger of AWS.  Approval and adoption of the Agreement and Plan
             -----------------                                                  
          of Merger, dated as of February 6, 1998, entered into by and among USA
          Waste Services, Inc. ("USA Waste"),  C & S Ohio Corp., and AWS (the
          "Merger Agreement") and the consummation of the Merger (as hereinafter
          defined) and related transactions contemplated therein, pursuant to
          which each outstanding share of AWS Common Stock will be converted
          into the right to receive $4.00 in cash.

                                       2
<PAGE>
 
     Each of the Proposals must be approved by the holders of the AWS Class A
Common Stock and by the holders of the AWS Class B Common Stock, each voting as
a separate class.  The affirmative votes of the holders of at least two-thirds
(66-2/3 percent) of the outstanding shares of each class is required to approve
each Proposal.  Holders of approximately 95 percent of the outstanding shares of
AWS Class B Common Stock have agreed, pursuant to voting agreements and
irrevocable proxies, to vote in favor of the Proposals.  The effectiveness of
each Proposal is conditioned upon approval of both Proposals.  Accordingly, the
failure of the AWS Class A stockholders to approve either of the Proposals will
result in the failure to consummate both the Spin-off and the Merger.

     The Board of Directors of AWS (the "AWS Board") unanimously recommends that
stockholders vote for the Proposals.

Special Meeting Record Date
    
     The AWS Board has fixed the close of business on May 11, 1998 as the record
date (the "Special Meeting Record Date") for the determination of the holders of
AWS Common Stock entitled to receive notice of and to vote at the Special
Meeting.
     
Votes Required

     Each holder of record of AWS Class A Common Stock as of the Special Meeting
Record Date is entitled to one vote for each share held.  The affirmative vote
of the holders of at least two-thirds (66-2/3 percent) of the outstanding shares
of AWS Class A Common Stock, voting as a separate class, is required to approve
each Proposal.

     Each holder of record of AWS Class B Common Stock as of the Special Meeting
Record Date is entitled to ten votes for each share held.  The affirmative vote
of the holders of at least two-thirds (66-2/3 percent) of the outstanding shares
of AWS Class B Common Stock, voting as a separate class, is also required to
approve each Proposal.  Holders of approximately 95 percent of the outstanding
shares of AWS Class B Common Stock have agreed, pursuant to voting agreements
and irrevocable proxies, to vote in favor of the Proposals.  The effectiveness
of each Proposal is conditioned upon approval of both Proposals.  Accordingly,
the failure of the holders of the AWS Class A Common Stock to approve either of
the Proposals will result in the failure to consummate both the Spin-off and the
Merger.  Failure to submit a proxy (or to vote in person) or an abstention from
voting will have the same effect as a vote against the Proposals.
    
     As of May 11, 1998, there were 25,301,308 shares of AWS Class A Common
Stock outstanding and entitled to vote at the Special Meeting and 5,123,858
shares of AWS Class B Common Stock outstanding and entitled to vote at the
Special Meeting.
     
     For additional information relating to the Special Meeting, see "The
Special Meeting."

The Transactions

Overview

     The Proposals contemplate that the transportation operations, technical
environmental services operations, waste disposal brokerage and management
operations, and golf course and related operations of AWS (together, the "Avalon
Business") will be separated from the solid waste disposal operations, refuse
collection operations and landfill gas operations of AWS.  Promptly thereafter,
AWS will merge with C & S Ohio Corp. and become a wholly owned subsidiary of USA
Waste.  The principal components of the transactions are as follows:

     The Spin-off.  AWS will contribute the Avalon Business (together with
     ------------                                                         
     certain other assets of AWS) to Avalon and will distribute all of the
     outstanding shares of capital stock of Avalon to the holders of AWS Common
     Stock on a pro rata and corresponding basis.  Holders of AWS Class A Common
     Stock will receive shares of Avalon's Class A common stock, $.01 par value
     ("Avalon Class A Common Stock"), and holders of AWS Class B Common Stock
     will receive shares of Avalon's Class B common stock, $.01 par value
     ("Avalon Class B Common Stock" and, together with the Avalon Class A Common
     Stock, the "Avalon Common Stock").  See "The Transactions--The Spin-off and
     the Distribution Agreement."

     The Merger.  After the Spin-off, in accordance with the terms of the Merger
     ----------                                                                 
     Agreement and the Ohio General Corporation Law, AWS will merge with C & S
     Ohio Corp. and will, as a result, become a wholly owned subsidiary of USA
     Waste (the "Merger").  By virtue of the Merger, each outstanding share of
     AWS Common Stock will be converted into the right to receive $4.00 in cash.
     See "The Transactions--The Merger and the Merger Agreement."

     The Spin-off and the Merger, together with the related transactions
described herein, are collectively hereinafter referred to as the
"Transactions."

     AWS will not effect the Spin-off in the event that the Proposals are not
approved at the Special Meeting.

     Following the Transactions, it is expected that the shares of Avalon Class
A Common Stock distributed in the Spin-off will be listed on the American Stock
Exchange under the symbol "AWX."

Effect on Stockholders

     The AWS Class A Common Stock had a closing price in composite trading on
the New York Stock Exchange (the "NYSE") on February 6, 1998 (the last day of
trading prior to the announcement by AWS of the Transactions) of $2.00 per
share.  The AWS Class A Common Stock traded as high as $2.0625 per share and as
low as $1.875 per share on that day.  In the Spin-off, each stockholder of AWS
will retain its shares of AWS Common Stock, and for each eight shares of AWS
Common Stock held by AWS stockholders on the Transactions Record

                                       4
<PAGE>
 
Date (as hereinafter defined), such stockholders will be entitled to receive one
share of Avalon Common Stock. Holders of AWS Class A Common Stock will receive
Avalon Class A Common Stock, with one vote per share, and holders of AWS Class B
Common Stock will receive Avalon Class B Common Stock, with ten votes per share.
See "The Transactions--The Spin-off and the Distribution Agreement--
Distribution" and "Description of Avalon Capital Stock." Promptly after the
Spin-off, by virtue of the Merger, each outstanding share of AWS Common Stock
will be converted into the right to receive $4.00 in cash. See "The
Transactions--The Merger and the Merger Agreement--Manner and Basis for
Converting Shares."

Business and Properties of Avalon

     Avalon will conduct the transportation operations, technical environmental
services operations, waste disposal brokerage and management operations, and
golf course and related operations that are currently conducted by AWS and
certain of its subsidiaries.  These operations of the Avalon Business
represented approximately 74.5% of the net operating revenues of AWS for the
year ending December 31, 1997.  The Avalon Business's assets were approximately
$44.5 million at December 31, 1997, which represented 36.1% of AWS's total
assets as of such date.  See "Business and Properties of Avalon."

     Avalon's address is One American Way, Warren, Ohio 44484-5555, and its
telephone number is (330) 856-8800.

Recommendation of the AWS Board

     The AWS Board believes that the Transactions will significantly enhance
stockholder value by providing stockholders with $4.00 in cash for each share of
AWS Common Stock and a continuing ownership interest in the Avalon Business.
For a discussion of the factors considered by the AWS Board in reaching its
decision with respect to the Transactions, see "Background and Reasons--
Reasons."

     The AWS Board unanimously recommends that stockholders vote for the
Proposals.

    

Market Valuation of Avalon

  AWS retained Houlihan, Lokey, Howard & Zukin Financial Advisors, Inc.
("Houlihan Lokey") to render a written opinion (the "Opinion") as to the fair
market value of the capital stock of Avalon that will be outstanding after the
Spin-off to serve as a valuation basis for establishing the amount of any
taxable gain resulting from the Spin-off.  Based upon the investigation,
premises, provisos, and analyses set forth in the Opinion and outlined below,
the Opinion, dated April 20, 1998, states that, as of March 31, 1998, the fair
market value of the capital stock of Avalon is reasonably stated in the amount
of $30,425,160.  This equates to $8.00 per share of Avalon Common Stock based on
3,162,576 shares of Avalon Class A Common Stock and 640,569 shares of Avalon
Class B Common Stock outstanding after the Spin-off or $1.00 per share of AWS
Common Stock based on 25,300,608 shares of AWS Class A Common
     
                                       5
<PAGE>
     
Stock and 5,124,558 shares of AWS Class B Common Stock outstanding as of March
31, 1998. See "Risk Factors--Risk Factors Regarding the Spin-off--Listing and
Trading of Avalon Class A Common Stock; No Prior Public Market" and `Background
and Reasons--Market Valuation of Avalon."
     
Certain Federal Income Tax Consequences

     As a result of the Spin-off, AWS will be required to recognize taxable gain
to the extent of the excess, if any, of the fair market value of the outstanding
shares of Avalon Common Stock over AWS's adjusted basis in those shares.  In
addition, each holder of shares of AWS Common Stock will be deemed to have
received, to the extent of AWS's current and accumulated earnings and profits, a
taxable dividend includable in income in an amount equal to the fair market
value of the shares of Avalon Common Stock received in the Spin-off, plus the
cash received, if any, in lieu of a fractional share of Avalon Common Stock.
Additionally, the receipt of cash for AWS Common Stock pursuant to the Merger
will be a taxable transaction for federal income tax purposes.  See "Certain
Federal Income Tax Consequences of the Transactions to AWS and its
Stockholders."

Dissenters' Rights

     Holders of shares of AWS Common Stock have the right to dissent from the
Merger and to receive payment of the "fair cash value" of their shares upon full
compliance with Section 1701.85 of the Ohio Revised Code ("Section 1701.85").
"Fair cash value" may be higher or lower than the $4.00 per share cash
consideration to be paid pursuant to the Merger.  See "Dissenters' Rights."

Risk Factors

     Stockholders should carefully evaluate the matters set forth under "Risk
Factors," in addition to the other matters described herein when deciding
whether to approve the Proposals.

Accounting Treatment

  In the separate financial statements of Avalon, the assets and liabilities
contributed to Avalon will be recorded at AWS's historical basis.  The
acquisition of AWS by USA Waste by means of the Merger will be accounted for as
a purchase.  See "Accounting Treatment."

USA Waste Services, Inc. and C&S Ohio Corp.

     USA Waste is the third largest integrated, nonhazardous solid waste
management company in North America, as measured by revenues for the nine months
ended September 30, 1997, and serves commercial, industrial, municipal and
residential customers in various locations in the United States, Canada, Puerto
Rico and Mexico.  USA Waste's solid waste management services include
collection, transfer and disposal operations and, to a lesser extent, recycling
and certain other waste management services. As of September 30, 1997, USA Waste
owned or

                                       6
<PAGE>
 
operated 161 landfills, 159 transfer stations and 381 collection companies and
served more than 7.5 million commercial, industrial, municipal and residential
customers.

     C&S Ohio Corp. is a wholly owned subsidiary of USA Waste organized for the
purpose of effecting the Merger.  C&S Ohio Corp. has no material assets and has
not engaged in any activities except in connection with the Merger. The
principal executive offices of USA Waste and C&S Ohio Corp. are located at First
City Tower, 1001 Fannin, Suite 4000, Houston, Texas 77002, and the telephone
number is (713) 512-6200.

     On March 11, 1998, USA Waste announced that it has signed a definitive
agreement to merge with Waste Management, Inc. ("Waste Management").  Waste
Management, based in Oak Brook, Illinois, is the leading international provider
of comprehensive waste management services, and it operates throughout the
United States and in select international markets.  In this proposed merger,
which has been approved unanimously by the boards of both companies, each share
of Waste Management common stock will be exchanged for 0.725 of a share of USA
Waste common stock, resulting in a total of approximately 565 million
outstanding shares for the combined company.  Waste Management's stockholders
will own approximately 60 percent of the combined enterprise, which based on the
closing stock prices on March 10, 1998 would have an aggregate equity market
capitalization in excess of $20 billion.

        SUMMARY OF SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA OF
                              THE AVALON BUSINESS

     The following table sets forth certain historical combined financial data
for the Avalon Business for fiscal years 1993 through 1997.  The summary
historical combined financial data for the three years ended December 31, 1997
and as of December 31, 1997 and 1996 were derived from the audited combined

ended December 31, 1997 reflects the historical results of the Avalon Business
as if the Transactions had occurred on January 1, 1997.  The summary unaudited
pro forma balance sheet data at December 31, 1997 reflects the historical
results of the Avalon Business after giving effect to the Transactions as if the
Transactions had occurred on December 31, 1997.

     The pro forma information presented is for informational purposes only and

results of operations or financial position would have been had the Transactions
occurred as of the dates indicated.  This information does not reflect future

                                  RISK FACTORS

     Stockholders of AWS should be aware that the Spin-off and ownership of
Avalon Common Stock involve certain risk factors, including those described
below and elsewhere in this Proxy Statement, that could adversely affect the
value of their holdings.  Neither AWS nor Avalon is making, nor is any other
person authorized to make, any representation as to the future market value of
the Avalon Common Stock.

Risk Factors Regarding the Spin-off


     The following are risks that may affect Avalon and/or its
stockholders as a result of the Spin-off:

Absence of History as an Independent Company; Less Diversified Operations

     The Avalon Business has historically been conducted by AWS as part of its
overall operations and, accordingly, Avalon does not have an operating history
as an independent company.  After the Spin-off, Avalon will no longer be able to
offer nonhazardous waste disposal services to third parties without making
arrangements with AWS or another provider of nonhazardous disposal facilities.

     Avalon was formed in April 1998 solely for the purpose of effecting the
Spin-off.  Thus, the financial information included herein does not necessarily
reflect the results of operations, financial position and cash flows of Avalon
had Avalon been operated independently during the periods presented.  There is
no assurance that, as a stand-alone company, Avalon's results of operations will
continue at a level similar to its results of operations while a part of AWS.
Avalon also believes that its selling, general and administrative expenses and
costs of operations will be significantly higher than the expenses reflected in
the historical financial statements of the Avalon Business because certain
selling, general and administrative expenses and costs of operations of AWS that
have historically not been allocated to any subsidiary of AWS or have
historically been allocated to subsidiaries of AWS that are not part of the
Avalon Business will be selling, general and administrative expenses and costs
of operations of Avalon.  See the Historical Combined Financial Statements of
the Avalon Business of American Waste Services, Inc. and notes thereto and the
Unaudited Pro Forma Combined Financial Information and notes thereto included
elsewhere herein.  Subsequent to the Transactions, Avalon will be a less
diversified company than is currently the case with respect to AWS.  As a
result, Avalon may be more susceptible to competitive and market factors than
the Avalon Business was as part of AWS.

Listing and Trading of Avalon Class A Common Stock; No Prior Public Market

     Avalon has applied to list the shares of Avalon Class A Common Stock to be
distributed in the Spin-off (the "Shares") on the American Stock Exchange, but
there is presently no public market for the Shares and there can be no assurance
that an active market will develop following the Spin-off.  The prices at which
the Avalon Class A Common Stock will trade after the Spin-

                                       10
<PAGE>
 
off will be determined by the marketplace and will be influenced by many
factors, including the depth and liquidity of the market for the Avalon Class A
Common Stock, investors' perceptions of Avalon, its prospects and the industries
in which it participates, Avalon's dividend policy, variations in Avalon's
operating results, changing economic conditions in the industries in which
Avalon participates, changes in governmental regulations and general economic
and market conditions. In addition, the general stock market has in recent years
experienced significant price fluctuations, often unrelated to the operating
performance of the specific companies whose stock is traded. Market
fluctuations, as well as economic conditions, may also adversely affect the
market price of the Avalon Class A Common Stock. Furthermore, given the
relatively small market capitalization of Avalon, the market for the Shares may
be subject to greater volatility than would be the case for a larger company.
See "Listing and Trading of Shares of Avalon Class A Common Stock."

Certain Federal Income Tax Considerations

     As a result of the Spin-off, AWS will be required to recognize taxable gain
to the extent of the excess, if any, of the fair market value of the outstanding
shares of Avalon Common Stock over AWS's adjusted basis in those shares.  In
addition, each holder of shares of AWS Common Stock will be deemed to have
received, to the extent of AWS's current and accumulated earnings and profits, a
taxable dividend includable in income in an amount equal to the fair market
value of the shares of Avalon Common Stock received in the Spin-off, plus the
cash received, if any, in lieu of a fractional share of Avalon Common Stock.
Additionally, the receipt of cash for AWS Common Stock pursuant to the Merger
will be a taxable transaction for federal income tax purposes.  See "Certain
Federal Income Tax Consequences of the Transactions to AWS and its
Stockholders."

Financing

     To the extent the Avalon Business has required outside financing, those
financing requirements have historically been supported by AWS.  Avalon does not
intend to establish its own credit facilities prior to the Spin-off.  Avalon
believes that the cash it will have on hand after the Transactions, as well as
cash flow from operations, will initially be adequate to fund Avalon's capital
expenditure and working capital requirements.  To the extent required in the
future, any credit agreements will contain customary financial and other
covenants and provisions.   Among other things, any credit agreement may
restrict the payment of dividends by Avalon by limiting the amount of dividends
or by requiring the maintenance of certain financial ratios as a condition to
the payment of dividends.

Dependence Upon Certain Customers

     Historically, a significant portion of Avalon's transportation revenues was
a result of AWS's disposal business.  The transportation services operations of
Avalon obtained approximately 14%, 14% and 13% of their net operating revenues
from AWS's disposal subsidiaries in 1997, 1996 and 1995, respectively.  Upon
consummation of  the Transactions, those disposal facilities and transportation
operations will no longer be affiliated.  Therefore,

                                       11
<PAGE>
 
there can be no assurance that such transportation services and resulting
revenues will continue in the future. The loss of such revenues could, if not
replaced, have an adverse impact upon Avalon.

Cancelable Contracts

     Many of the services provided by Avalon are terminable by customers on
short notice.  If customers react unfavorably to the Transactions, such
customers may decide to terminate such services which could adversely affect the
business and operations of Avalon.

Additional Risk Factors Regarding Ownership of Avalon


     The following are additional risks that currently may affect AWS
and/or its stockholders which, after the Spin-off, may also affect Avalon and/or
its stockholders:

Environmental Liability; Environmental Liability Insurance

     Avalon may be subject to liability for environmental contamination caused
by pollutants the transportation, treatment or disposal of which was arranged
for by Avalon or one of its predecessors.  For the years 1997, 1996 and 1995,
net operating revenues related to these activities represented approximately
44%, 40% and 42%, respectively, of Avalon's net operating revenues.  Avalon has
pollution endorsements to its automotive liability insurance policies that cover
certain (but not all) environmental liabilities to third parties from Avalon's
transportation operations.  In addition, no assurance can be given that such
insurance will be available in the future or, if available, that the premiums
for such insurance will be reasonable.  Although Avalon has compliance
guidelines for its transportation operations, Avalon could still incur a
substantial liability for environmental damage not covered by such insurance or
in excess of its policy limits or at a time when Avalon no longer is able to
obtain appropriate insurance, in any which case, its condition could be
materially adversely affected.  See "Business and Properties of Avalon--
Insurance."

Competition

     The markets for the transportation of hazardous and nonhazardous waste and
for the transportation of general and bulk commodities are each highly
competitive.  There are numerous participants, and no one transporter has a
dominant market share.  Avalon competes primarily with other short and long-haul
carriers for both truckload and less than truckload shipments.  Competition for
the transportation of waste is based on the ability of the carrier to transport
the waste at a competitive price and in accordance with applicable regulations
and the latest advances in technology.  Competition for the transportation of
commodities is based primarily on price and service.

     Avalon's technical environmental services operations compete with numerous
large and small companies, each of which is able to provide one or more of the
environmental services offered by Avalon and some of which have greater
financial resources.  Avalon attempts to

                                       12
<PAGE>

develop relationships with clients who have an ongoing need for its integrated
technical environmental services. The availability of skilled technical
personnel, the quality of performance and service, and fees are the key
competitive factors in developing such relationships.

     The hazardous and nonhazardous waste disposal brokerage and management
business is highly competitive and fragmented.  Avalon's waste disposal
brokerage and management business competes with other brokerage companies as
well as with companies which own treatment and disposal facilities.

Governmental Regulations

     In order to transport hazardous waste and, in certain cases, nonhazardous
solid waste, Avalon must possess and maintain one or more state operating
permits.  These operating permits must be renewed annually and are subject to
modification and revocation by the issuing agency.  In addition, Avalon's waste
transportation operations are subject to evolving and expanding operational,
monitoring and safety requirements.

     In the ordinary course of its transportation operations, Avalon may from
time to time receive citations, notices or comments from regulatory authorities
stating that such operations are not in compliance with applicable environmental
regulations.  These agencies may seek to impose fines on Avalon or to revoke or
deny renewal of Avalon's operating permits or licenses or to require Avalon to
remediate environmental problems resulting from its transportation or waste
disposal brokerage and management operations.  Upon receipt of such citations,
notices or comments, Avalon will work with the authorities in an attempt to
resolve the issues raised.  Failure to correct the problems to the satisfaction
of the authorities could lead to fines and/or a curtailment or cessation of such
operations.

     The federal government and numerous state and local governmental bodies are
increasingly considering, proposing or enacting legislation or regulations to
either restrict or impede the disposal and/or transportation of waste.  A
significant portion of Avalon's disposal brokerage and transportation revenues
is expected to be derived from the disposal or transportation of out-of-state
waste.  Any law or regulation restricting or impeding the transportation of
waste or the acceptance of out-of-state waste for disposal could have a
significant negative effect on Avalon.  Avalon's transportation operations may
also be affected by the trend toward laws requiring the development of waste
reduction and recycling or other programs.

Seasonal Nature of the Avalon Business

     The transportation, remediation portion of the technical environmental
services and golf course operations of Avalon are somewhat seasonal in nature
because a significant portion of these operations are performed primarily in
selected northeastern and midwestern states.  As a result, these operations may
be adversely affected by winter weather conditions.

Assumed Liabilities

     Pursuant to the Distribution Agreement, Avalon has agreed to assume certain
liabilities of AWS, including any liabilities relating to the termination of
employment of certain employees of AWS as a result of the Transactions and any
costs and potential liabilities relating to the legal proceeding captioned
Werbowsky vs American Waste Services, Inc., et al.
- ------------------------------------------------- 

Voting Control by Management

     After giving effect to the Spin-off, the holders of the Avalon Class B
Common Stock (which has ten votes per share), consisting principally of the
management of Avalon, will have approximately 65 percent of the aggregate voting
power of the outstanding Avalon Common Stock.  Thus, the holders of the Avalon
Class A Common Stock (which has one vote per share) will not, either alone or
acting collectively, be able to elect a majority of the members of Avalon's
Board of Directors (the "Avalon Board") or control many corporate actions.
However, the holders of the Avalon Class A Common Stock will have the right,
commencing with the first annual meeting of stockholders after the Spin-off, to
elect 25 percent of the directors of Avalon until the outstanding Avalon Class B
Common Stock constitutes less than 50 percent of the total voting power of the
outstanding Avalon Common Stock, after which time the holders of the Avalon
Class A and Class B Common Stock will vote as a single class for the election of
directors.  See "Description of Avalon Capital Stock--Voting Rights" and
"Management of Avalon--Avalon Board of Directors."

Certain Anti-Takeover Provisions of Articles
of Incorporation, Code of Regulations and Ohio Law

     The Articles of Incorporation (the "Avalon Articles") and Code of
Regulations (the "Avalon Code") of Avalon, as well as Ohio statutory law,
contain provisions that may have the effect of discouraging an acquisition of
control of Avalon not approved by the Avalon Board.  Such provisions may also
have the effect of discouraging third parties from making proposals involving an
acquisition or change of control of Avalon, although such proposals, if made,
might be considered desirable by a majority of the Avalon stockholders.  Such
provisions could also have the effect of making it more difficult for third
parties to cause the replacement of the current management of Avalon without the
concurrence of the Avalon Board.  These provisions have been designed to enable
Avalon to develop its business and foster its long-term growth without
disruptions caused by the threat of a takeover not deemed by the Avalon Board to
be in the best interests of Avalon and its stockholders.  See "Description of
Avalon Capital Stock--Voting Rights," "--Certain Effects of Authorized But
Unissued Stock" and "--Certain Anti-Takeover Provisions of the Articles of
Incorporation, Code of Regulations and Ohio Law."

Dividend Policy

     The dividend policy of Avalon will be determined by the Avalon Board.  The
future payment of dividends will depend on business decisions that will be made
by the Avalon Board from time to time based on the results of operations and
financial condition of Avalon and such

                                       14
<PAGE>
 
other business considerations as the Avalon Board considers relevant. It is
currently anticipated that any Avalon earnings will be retained for use in its
business and Avalon does not intend to pay cash dividends on the Avalon Common
Stock in the foreseeable future.

Inflation

     Avalon has not entered into any long-term fixed price contracts that could
have a material adverse impact upon its financial performance in periods of
inflation.  In general, management believes that rising costs resulting from
price inflation could be passed on to customers; however, Avalon may need to
absorb all or a portion of these cost increases depending upon competitive
conditions at the time.  As is the case with any transportation company, an
increase in fuel prices may subject Avalon's transportation operations to
increased operating expenses, which Avalon, in light of competitive market
conditions, may not be able to pass on to its customers.


                              THE SPECIAL MEETING

Date, Time And Place Of Special Meeting
    
     The Special Meeting of Stockholders of AWS will be held at 10:30 a.m.,
local time, at the Grand Pavilion, located at One American Way, Warren, Ohio, on
June 15, 1998.
     
Matters For Consideration At Special Meeting

     At the Special Meeting, the stockholders of AWS will be asked to consider
and vote on the following Proposals:


Proposal 1.  The spin-off of Avalon Holdings Corporation.  Approval of (i) the
             -------------------------------------------                      
          contribution by AWS to its wholly owned subsidiary, Avalon, of all
          businesses of AWS other than the nonhazardous solid waste landfills
          owned, the refuse collection services provided, and the landfill gas
          collection and sales business conducted by certain subsidiaries of
          AWS, and (ii) a special dividend to the holders of the outstanding
          shares of AWS Common Stock of all outstanding shares of capital stock
          of Avalon on a pro rata and corresponding basis, all to be effected in
          accordance with the terms of the Distribution Agreement.

Proposal 2.  The merger of AWS.  Approval and adoption of the Merger Agreement
             -----------------                                                
          and the consummation of the Merger and related transactions
          contemplated therein, pursuant to which each outstanding share of AWS
          Common Stock will be converted into the right to receive $4.00 in
          cash.

     The AWS Board unanimously recommends that stockholders vote for the
Proposals.

     Each of the Proposals must be approved by the holders of the AWS Class A
Common Stock and by the holders of the AWS Class B Common Stock, each voting as
a separate class.  Holders of approximately 95 percent of the outstanding shares
of AWS Class B Common Stock

                                       15
<PAGE>
 
have agreed, pursuant to voting agreements and irrevocable proxies, to vote in
favor of the Proposals. The effectiveness of each Proposal is conditioned upon
approval of both Proposals. Accordingly, the failure of the AWS Class A
stockholders to approve either of the Proposals will result in the failure to
consummate both the Spin-off and the Merger.

     For a description of the reasons for the Transactions, see "Background and
Reasons--Reasons."

Voting And Revocation Of Proxies

     Each holder of record of AWS Class A Common Stock as of the Special Meeting
Record Date is entitled to one vote for each share held.  The affirmative vote
of the holders of at least two-thirds (66-2/3 percent) of the outstanding shares
of AWS Class A Common Stock, voting as a separate class, is required to approve
each Proposal.

     Each holder of record of AWS Class B Common Stock as of the Special Meeting
Record Date is entitled to ten votes for each share held.  The affirmative vote
of the holders of at least two-thirds (66-2/3 percent) of the outstanding shares
of AWS Class B Common Stock, voting as a separate class, is also required to
approve each Proposal.  Holders of approximately 95 percent of the outstanding
shares of AWS Class B Common Stock have agreed, pursuant to voting agreements
and irrevocable proxies, to vote in favor of the Proposals.  The effectiveness
of each Proposal is conditioned upon approval of both Proposals.  Accordingly,
the failure of the holders of the AWS Class A Common Stock to approve either of
the Proposals will result in the failure to consummate both the Spin-off and the
Merger.  Failure to submit a proxy (or to vote in person) or an abstention from
voting will have the same effect as a vote against the Proposals.

     Shares of AWS Common Stock represented by a proxy properly signed and
received at or prior to the Special Meeting, unless subsequently revoked, will
be voted in accordance with the instructions thereon.  If a proxy is signed and
returned without indicating any voting instructions, the shares of AWS Common
Stock represented by that proxy will be voted for both Proposals.

     Abstentions may be specified on both Proposals.  Shares of AWS Common Stock
represented at the Special Meeting but not voted or for which proxies have been
received but with respect to which the holders of such shares have abstained on
any matter will be treated as present at the Special Meeting for purposes of
determining the presence or absence of a quorum for the transaction of all
business.

     For voting purposes at the Special Meeting, only shares affirmatively voted
in favor of a Proposal (including properly executed proxies not containing
voting instructions) will be counted as favorable votes for such Proposal.
Failure to submit a proxy (or to vote in person) or an abstention from voting
will have the same effect as a vote against the Proposals.  In addition, under
the applicable rules of the NYSE, brokers who hold shares in street name for
customers who are the beneficial owners of such shares are prohibited from
giving a proxy to vote such customers' shares with respect to the Proposals in
the absence of specific instructions from such

                                       16
<PAGE>
 
customers ("Broker Non-votes"). Broker Non-votes will also have the same effect
as votes against the Proposals. Stockholders who hold their shares of AWS Class
A Common Stock in street name are therefore urged to vote.

     Proxy holders may, in their discretion, vote shares to adjourn the Special
Meeting to solicit additional proxies in favor of the Proposals if their proxies
were returned with no instructions or with instructions to vote for the
Proposals.  However, shares of AWS Common Stock with respect to which a proxy is
signed and returned indicating a vote against or abstaining with respect to
either Proposal will not be so voted to adjourn.

     Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before the proxy is voted by the filing of an instrument
revoking it or of a duly executed proxy bearing a later date with the Secretary
of AWS prior to or at the Special Meeting or by voting in person at the Special
Meeting.  All written notices of revocation and other communications with
respect to revocation of proxies should be addressed to American Waste Services,
Inc., c/o American Stock Transfer & Trust Company, 40 Wall Street, New York, New
York 10005.  Attendance at the Special Meeting will not in and of itself
constitute revocation of a proxy.

     AWS stockholders will not be entitled to present any matters for
consideration at the Special Meeting, and the AWS Board is not currently aware
of any business to be acted upon at the Special Meeting other than as described
herein.  If, however, other matters are properly brought before the Special
Meeting, the persons appointed as proxies will have discretion to vote or act
thereon according to their best judgment.

Solicitation Of Proxies

     In addition to solicitation by mail, directors, officers and employees of
AWS, who will not be specifically compensated for such services, may solicit
proxies from the stockholders of AWS personally or by telephone, telecopy,
telegram or other forms of communication.  Brokers, nominees, fiduciaries and
other custodians will be requested to forward soliciting materials to beneficial
owners and will be reimbursed for their reasonable expenses incurred in sending
proxy materials to beneficial owners.

     AWS has retained Corporate Investor Communications, Inc. to assist in the
solicitation of proxies.  The fees to be paid to such firm for such services by
AWS are not expected to exceed $6,000, plus reasonable out-of-pocket costs and
expenses.  AWS will pay the costs incurred in printing this Proxy Statement.

                             BACKGROUND AND REASONS

Background of the Transactions

     Over the past several years, representatives of AWS have on occasion had
discussions regarding a possible business combination with various companies in
the waste management

                                       17
<PAGE>
 
industry. In each such instance, it was concluded that a business combination
would not be advisable and/or that potential negotiations on material terms were
unlikely to be successful. Throughout that period, the AWS Board gave
consideration to the changes occurring in the waste management industry and how
AWS might respond to those changes in a manner which would potentially increase
stockholder value.

     In February 1997, Charles A. Wilcox (Vice President, Central Region of USA
Waste) met with Ronald E. Klingle (Chairman and Chief Executive Officer of AWS)
and Robert M. Arnoni (a director of AWS) to discuss a matter relating to Mr.
Arnoni.  During the course of that meeting, Messrs. Wilcox and Klingle discussed
several possible transactions between USA Waste and AWS, including USA Waste
utilizing AWS's disposal facilities as a customer and USA Waste acquiring AWS's
disposal facilities and collection operations.  No agreement was reached on any
of those transactions, nor did Messrs. Wilcox and Klingle agree to continue
talking about them.

     In August 1997, at Mr. Wilcox's request, Mr. Wilcox and Mr. Klingle met in
Pittsburgh, Pennsylvania to discuss USA Waste's interest in acquiring AWS's
disposal and collection businesses.  Mr. Wilcox emphasized that USA Waste was
not interested in acquiring any of the other businesses of AWS.  Mr. Klingle
indicated to Mr. Wilcox that, if such a transaction were to occur, it must be
structured in such a manner so that, to the extent possible, any taxes incurred
by AWS's stockholders in connection with the transaction be at capital gains
rates.

     At that meeting and over the next few weeks, the parties discussed possible
prices for AWS's disposal and collection businesses.  At the end of those
discussions, Mr. Wilcox indicated that USA Waste might be willing to acquire
those businesses on the terms being sought by AWS management depending upon the
results of a thorough investigation of the AWS disposal and collection
businesses.  Mr. Klingle consulted with Darrell D. Wilson (President and Chief
Operating Officer of AWS) and Sanford B. Ferguson (a director of AWS) and then
advised Mr. Wilcox that AWS would permit such an investigation following receipt
of an appropriate confidentiality agreement.  On October 2, 1997, Mr. Wilcox
executed a confidentiality agreement on behalf of USA Waste.

     During October and November 1997, USA Waste conducted a due diligence
investigation of AWS's disposal facilities and collection operations.  During
November 1997, Mr. Klingle briefed each AWS Board member regarding the
discussions with USA Waste and discussed generally with each AWS Board member
the potential advantages of a business combination of USA Waste and AWS on the
terms being discussed with USA Waste.

     Throughout November and December 1997, both companies and their respective
tax advisors gave considerable attention to the structuring of a possible
transaction in which USA Waste would acquire less than all of the businesses of
AWS and the tax implications relating thereto.  Concurrently, Messrs. Klingle
and Wilcox continued to discuss the appropriate purchase price for the disposal
and collection businesses of AWS and the manner and timing of payment thereof.

                                       18
<PAGE>
 
     At the AWS Board's regularly scheduled meeting in December 1997, Mr.
Klingle reported in depth on the discussions with USA Waste and made a
presentation regarding the strategic considerations facing AWS.  The AWS Board
felt that the purchase price being sought by AWS management for the disposal and
collection businesses might be appropriate, depending upon the resolution of the
structuring issues raised by Mr. Klingle.  The AWS Board evaluated the
advisability of contacting other potentially interested parties with respect to
AWS's possible interest in a business combination.  The AWS Board weighed the
likelihood of reaching a desirable agreement with USA Waste, the risk to the
proposed transaction with USA Waste from approaching other potentially
interested parties, and the probability that one of these potentially interested
parties would agree to a transaction superior to the proposed transaction with
USA Waste.  The AWS Board also took into account the potentially unsettling
impact on the customers and employees of AWS that a broader-based or protracted
sale process might entail.  The AWS Board considered, in addition, whether to
retain a financial advisor in connection with a possible transaction and whether
to obtain a fairness opinion with respect to any proposed purchase price.  The
AWS Board concluded that it did not require such assistance at this time.  The
AWS Board also concluded that it was not advisable to authorize management to
contact other potentially interested parties.  The AWS Board instead authorized
management to continue discussions with USA Waste.

     By the end of December 1997, Messrs. Wilcox and Klingle agreed that their
discussions concerning the terms of a spin-off of the AWS businesses that USA
Waste did not want and an acquisition of the remaining AWS businesses by USA
Waste had progressed to the point that an attempt should be made to prepare
definitive documentation.  During January 1998, the parties and their counsel
negotiated the various agreements and USA Waste continued its due diligence
investigation.

     Commencing on February 3, 1998, the parties sought to complete all
agreements subject to final review and approval by the AWS Board.  On February
6, 1998, the AWS Board held a special meeting at which (i) the AWS Board
reviewed with AWS's senior management and legal advisors the proposed terms of
the Transactions and the anticipated effects of the Merger and the Spin-off on
AWS and its stockholders; (ii) members of AWS's senior management and legal
advisors made presentations concerning the Transactions; and (iii) members of
the AWS Board were afforded the opportunity to raise and have answered any
questions they had regarding the acquisition and spin-off documents previously
provided to them.  At such meeting, the AWS Board concluded that the Merger
would be in the best interest of AWS and its stockholders and therefore
unanimously approved the Merger Agreement and the transactions contemplated
thereby and resolved to recommend that the stockholders of AWS vote in favor of
the Merger and approval and adoption of the Merger Agreement.  The Merger
Agreement was executed by all parties immediately following that special meeting
and a public announcement was made by AWS immediately thereafter.

    
     On May 7, 1998, the AWS Board held a special meeting at which the AWS Board
(i) reviewed the terms of the Distribution Agreement, including the terms of the
contribution of the Avalon Business (and certain other assets of AWS) to Avalon
and the related assumption of certain liabilities by Avalon; (ii) reviewed the
Opinion of Houlihan Lokey concerning the fair
     
                                       19
<PAGE>
market value of the capital stock of Avalon; (iii) concluded that the
contribution of the Avalon Business (and certain other assets of AWS) to Avalon
and the Spin-off would be in the best interests of AWS and its stockholders;
(iv) authorized the contribution of the Avalon Business (and certain other
assets of AWS) to Avalon in accordance with the terms of the Distribution
Agreement; (v) declared the Spin-off, subject to the satisfaction or waiver of
all the conditions precedent thereto; and (vi) resolved to recommend that the
stockholders of AWS vote in favor of that contribution and the Spin-off.

Reasons

     When considering whether to approve the Transactions, the AWS Board took
into consideration a number of factors, including:  (i) the state of the waste
management industry over the last several years and the prospects for the
industry in general; (ii) the financial condition and results of operations of
AWS over the same time period and the AWS Board's views of the prospects for AWS
given developments in the industry; (iii) the trading prices of the AWS Class A
Common Stock over the last several years in comparison to the price being
offered by USA Waste; (iv) the likely starting financial position and prospects
of Avalon; (v) the potential effects on AWS of entering into the Merger
Agreement and preparing for the Transactions if the Transactions are not
consummated for any reason; and (vi) the fact that the Merger Agreement did not
preclude the AWS Board from negotiating with anyone who would be willing to pay
a higher price for AWS.  Given its views on all of these factors and others, the
AWS Board determined that the Transactions would significantly enhance
stockholder value by providing AWS stockholders with $4.00 in cash for each
share of AWS Common Stock and a continuing ownership interest in the Avalon
Business.


     When considering the state of the waste management industry over the last
several years and its prospects, the AWS Board took into account management's
assessment that the historical consolidation within the waste management
industry would continue in the future and that many of the remaining locally
owned collection and disposal companies would likely be acquired by larger
regional and national companies.  The AWS Board recognized that these larger
companies prefer to direct the solid waste they collect to their own landfills
rather than to landfills owned by others.  Many local independent collection
companies utilize AWS's landfills.  If these companies continued to be acquired
as part of the industry consolidation, management believed that AWS's landfills
would no longer receive the volumes of solid waste they historically had
received from these companies.  Although AWS had generally been successful in
replacing much of the volumes of solid waste lost as a result of industry
consolidation and other competitive factors in the past, management could not
assure the AWS Board that it would be as successful in the future.

     The AWS Board also reviewed the historical financial condition and results
of operations of AWS focusing on the contribution to earnings provided to AWS by
the operations proposed to be acquired by USA Waste.  Although the AWS Board
believed that the financial condition of AWS was strong and would likely remain
so in the foreseeable future, the AWS Board believed that if AWS continued to
operate its landfills and collection companies, it could not provide the AWS
stockholders with the same benefits that the consummation of the Transactions
offered the

                                       20
<PAGE>
 
AWS stockholders.

     The AWS Board also noted that during the twelve-month period ending prior
to the special meeting of the AWS Board on February 6, 1998, the AWS Class A
Common Stock traded in a range of $1.25 to $2.25 per share.  Thus, the cash
consideration of $4.00 per share represented a premium of 78% to 220% over the
trading range of the AWS Class A Common Stock prior to that special meeting
date, without even taking into consideration the value of the Avalon Common
Stock to be received as a dividend by AWS stockholders.

     The AWS Board also considered the likely starting financial position and
prospects of Avalon.  The AWS Board believed that the Transactions would provide
Avalon with a strong initial financial position, including working capital of up
to approximately $29 million.  When reviewing the anticipated initial balance
sheet of Avalon, the AWS Board noted that the liabilities which Avalon would
assume were reasonable in that they were either attributable to the operations
of the Avalon Business or had been appropriately taken into account during
management's negotiations with representatives of USA Waste.  Although the
operations to be contributed to Avalon had not significantly contributed to the
earnings of AWS in the past, the AWS Board was of the view that a major reason
for this was that management had historically directed AWS's financial and non-
financial resources primarily on the disposal and collection operations and not
on the transportation and technical services companies.  Furthermore, although
AWS's transportation and technical services operations have provided numerous
supporting services to AWS's solid waste disposal operations, the AWS Board
believed that the transportation and technical services operations had been
significantly limited in their ability to provide the same services to other
companies in the solid waste disposal industry because AWS was viewed as a
competitor by those companies.  The AWS Board believes that, following
consummation of the Transactions, Avalon will not be viewed by those other
companies as a competitor, and significant opportunities will exist to provide
supporting services to these other companies in the waste management industry.

     The AWS Board also believed that the proposal being made by USA Waste was
an opportunity that would possibly not be available in the future.  The AWS
Board believed that AWS's landfill operations were likely at the peak of their
saleable values for the foreseeable future based upon, among other things, the
recently received permits upgrading the facilities to best available technology
standards, current disposal capacities and expansion availability, and the
current values that acquiring companies are placing on disposal operations in
light of the continuing consolidation within the waste management industry.
Furthermore, the AWS Board took into account the fact that the Merger Agreement
did not preclude it from negotiating with anyone who would be willing to pay a
higher price for AWS.

     The AWS Board also recognized the negative effects on AWS of entering into
the Merger Agreement and preparing for the Transactions if the Transactions are
not consummated for any reason.  The AWS Board acknowledged that a significant
portion of management's efforts would be focused on the steps necessary to
consummate the Transactions, including those associated with the Special
Meeting, rather than on improving AWS's prospects.  Additionally, the costs and
expenses relating to the Transactions, including those associated with the
Special Meeting,

                                       21
<PAGE>
 
would be substantial and will be an expense of AWS whether the Transactions are
consummated or not. Furthermore, the AWS Board considered the potential loss of
key employees and customers as a result of the announcement of the Transactions.
As a result of the foregoing, the AWS Board recognized that if the Transactions
are not consummated, AWS's results of operation will be negatively impacted. The
AWS Board determined that because the Transactions would significantly enhance
stockholder value by providing AWS stockholders with $4.00 in cash for each
share of AWS Common Stock and a continuing ownership interest in the Avalon
Business, the positive benefits to be realized if the Transactions are
consummated significantly outweighed the risks associated with the Transactions
not being consummated.
    
Market Valuation of Avalon

     Houlihan Lokey was retained by AWS to render the Opinion as to the fair
market value of the capital stock of Avalon that will be outstanding after the
Spin-off to serve as a valuation basis for establishing the amount of any
taxable gain resulting from the Spin-off.  As part of its investment advisory
services business, Houlihan Lokey renders opinions on the valuation of
businesses in connection with mergers and acquisitions and for corporate and
other purposes.  AWS chose Houlihan Lokey to prepare the Opinion because of
Houlihan Lokey's national reputation as an independent appraiser of the value of
companies.

     For purposes of the Opinion, dated April 20, 1998, the term "fair market
value" was defined as the amount at which shares of Avalon Common Stock would
change hands between a willing buyer and a willing seller, each having
reasonable knowledge of all relevant facts and neither being under any
compulsion to act, with equity to both.  Furthermore, for purposes of the
Opinion, Houlihan Lokey assumed that, after the Spin-off, the outstanding shares
of Avalon Common Stock will have been fully distributed, the Avalon Class A
Common Stock will be trading on an established market, and information
concerning Avalon of the type normally available concerning publicly-traded
companies will have been widely disseminated.

     The preparation of a valuation opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description.  Selecting
portions of the analyses or of the summary, without considering the analysis as
a whole, could create an incomplete view of the processes underlying the
Opinion.  In arriving at its valuation conclusions, Houlihan Lokey considered
the result of all such analyses.  The analyses were prepared for the purposes of
enabling Houlihan Lokey to render its Opinion to AWS as to the valuation of
Avalon for purposes of establishing the amount of taxable gain, if any, arising
from the Spin-off.  Analyses based upon forecasts of future results are not
necessarily indicative of actual future values, which may be significantly more
or less favorable than suggested by such analyses, nor should they be viewed as
predictions of potential future trading prices for shares of Avalon Common
Stock.
     
     In connection with the Opinion, Houlihan Lokey made such reviews, analyses
and inquiries as it deemed necessary and appropriate under the circumstances,
including, among other things, the following:  (i) meetings with certain members
of the senior management of AWS to discuss the operations, financial condition,
prospects and projected operations and performance of Avalon; (ii) visits to
certain facilities and business offices of AWS; (iii) AWS's

                                       22

annual reports to stockholders and annual reports on Form 10-K for the five
fiscal years ended December 31, 1997; (iv) the unaudited pro forma combined and
combining financial statements for the Avalon Business for the five years ended
December 31, 1997; (v) the forecasts and projections prepared by AWS's
management with respect to Avalon for the five years ending December 31, 2002;
(vi) the historical market prices and trading volume for the AWS Class A Common
Stock; (vii) certain publicly available financial data for certain companies
that Houlihan Lokey deemed comparable to Avalon; (viii) the preliminary proxy
statement of AWS with respect to, among other things, the Spin-off as filed with
the Securities and Exchange Commission (the "SEC") on March 16, 1998; (ix) the
Merger Agreement, the Distribution Agreement and the Tax Allocation Agreement
(as hereinafter defined); and (x) such other studies, analyses and inquiries as
Houlihan Lokey deemed appropriate.

    
     The financial forecasts and projections prepared by AWS's management with
respect to Avalon for the five years ending December 31, 2002 were based upon
the historical financial results of the Avalon Business while a part of AWS and
the material assumptions set forth below.  Revenues were projected to increase
each year by approximately 2.5% on a consolidated basis with each operation's
revenues increasing by a range of 0 to 5% annually.  Operating margins were
projected to approximate historical levels with the exception of the operating
margins for the technical environmental services operations, which had incurred
significant operating losses relating to specific remediation projects.  These
operating losses were not expected to be incurred in the future and as a result
were not factored into the projections.  The projections included management's
estimates of the additional costs of operations and selling, general and
administrative expenses expected to be incurred as a result of Avalon operating
as a stand-alone company and also included interest income on invested cash and
cash equivalents based upon a 5% annual interest rate.  The combined federal and
state income tax rate was estimated to be 40%.

     

     Houlihan Lokey relied upon the financial forecasts and projections provided
to it and assumed, without independent verification, that those financial
forecasts and projections had been reasonably prepared and reflected the best
currently available estimates of the future financial results and condition of
Avalon and that there had been no material change in the assets, financial
condition, business or prospects of Avalon since the date of the most recent
financial statements made available to it.  Houlihan Lokey did not independently
verify the accuracy and completeness of the information supplied to it with
respect to Avalon and does not assume any responsibility with respect thereto.
Houlihan Lokey did not make any independent appraisal of any of the properties
or assets of Avalon.

    
     As part of its analysis, Houlihan Lokey analyzed the trading value of AWS's
publicly traded securities, both before and after the announcement of the
Transactions.  AWS Class A Common Stock traded in the range of $1-5/16 to $2-1/4
per share in the year prior to the approval of the Merger Agreement on February
6, 1998, and closed at $1-7/8 per share on the day prior to the announcement.
Subsequent to the announcement and through March 31, 1998, AWS Class A Common
Stock traded in the range of $3-9/16 to $4 per share.  AWS Class A Common Stock
closed at $3-15/16 per share on March 31, 1998.  While Houlihan Lokey considered
this trading activity in its analysis, Houlihan Lokey utilized an independent
valuation

     
                                       23

analysis to determine the fair market value of the capital stock of Avalon that
will be outstanding after the Spin-off.

     The Avalon Business comprises four separate operating divisions:  (i)
transportation ("Transportation Operations"), (ii) technical environmental
services ("Technical Operations"), (iii) waste disposal brokerage and management
("Waste Disposal Operations"), and (iv) golf course and related ("Golf Course
Operations").  In its determination of the fair market value of the capital
stock of Avalon, Houlihan Lokey valued each operating division separately and
then considered the impact of corporate overhead, nonoperating assets and total
interest-bearing debt.
     

     In determining the fair market value of the Avalon Common Stock that will
be outstanding after the Spin-off, Houlihan Lokey considered generally accepted
valuation methodologies and, after such due consideration, utilized primarily
the capitalization of earnings and discounted cash flow approaches.

    
     The capitalization of earnings approach is a method of determining the fair
market value of a company by determining a level of earnings which is considered
to be representative of the future operating performance of the company and
capitalizing this level at a selected multiple.  Comparable public companies are
selected for comparison purposes and a risk analysis is performed.  The
selection of appropriate multiples for the company is made based on this
comparative risk analysis and a thorough analysis of the comparable market
multiples.  Capitalizing the representative levels at the selected multiple
determines the company's total enterprise value.  Certain adjustments for
nonoperating assets and interest-bearing debt are made to determine the fair
market value of the company's equity.

     The discounted cash flow approach is another method of determining the
value of an operating enterprise.  This approach entails determining the
appropriate cash flows, based upon projected financial information for the
enterprise.  An appropriate discount rate for the enterprise projections is
selected based upon an analysis of alternative investments.  The terminal value,
which is the value of the enterprise at the end of the projected period, is
determined by using the capitalization of earnings approach.  The summation of
the discounted value for the projected period and the discounted value of cash
flow for the terminal value determines the company's total enterprise value.
Similarly, to determine the fair market value of the company's equity,
adjustments for nonoperating assets and interest-bearing debt are made.

     The following is a summary of the application of these valuation
methodologies to each of the operating divisions.  After assessing each of the
operating divisions, Houlihan Lokey considered the valuation implications of
Avalon's corporate overhead charges, nonoperating assets and total interest-
bearing debt in rendering its opinion as to the fair market value of the Avalon
Common Stock.

Transportation Operations

     In the capitalization of earnings approach, Houlihan Lokey calculated
earnings levels which it considered to be representative of the future operating
performance of the

     
                                       24
<PAGE>
     
Transportation Operations. Houlihan Lokey reviewed and compared the financial,
operating and market performance of the Transportation Operations to the
following five companies selected from a review of various publicly traded
companies selected by Houlihan Lokey: Allied Waste Industries, Inc., American
Disposal Services, KTI, Inc., Superior Services, Inc., and Trism, Inc. (the
"Transportation Companies"). Houlihan Lokey examined certain publicly available
or estimated financial data of the Transportation Companies, including total
revenue, total assets, earnings before interest and taxes ("EBIT"), earnings
before interest, taxes, depreciation and amortization ("EBITDA"), interest-
bearing debt and net income. Houlihan Lokey also examined and compared various
operating ratios and certain capitalization data. Houlihan Lokey also reviewed
market data, including various trading multiples such as stock price to earnings
per share, enterprise value to EBIT, enterprise value to EBITDA, enterprise
value to debt-free earnings ("DFE") and enterprise value to debt-free cash flow
("DFCF"). Houlihan Lokey also considered other financial data (including margins
and growth rates) as well as certain operating information for the
Transportation Companies. Based upon Houlihan Lokey's review of this financial
and other information, Houlihan Lokey concluded that the Transportation
Operations represent a significantly greater investment risk, for a given
return, than the Transportation Companies taken as a group.

     Houlihan Lokey derived the capitalization rates for the Transportation
Companies by dividing the value of each company's total invested capital by the
next fiscal year ended estimates, latest 12 months, and latest fiscal year-end
average, EBITDA, EBIT, DFCF and DFE.  Houlihan Lokey defined total invested
capital ("TIC") as the book value of a company's debt plus the enterprise value
of the company's common equity.  The Transportation Companies' TIC/EBIT and
TIC/EBITDA multiples for the next fiscal year ranged from 8.8 to 13.3 and 7.2 to
9.2 with medians of 13.1 and 8.7, respectively.  TIC/DFE and TIC/DFCF multiples
for the next fiscal year ranged from 14.8 to 22.3 and 10.8 to 12.7, with medians
of 21.8 and 11.8, respectively.  Based on Houlihan Lokey's determination that
the Transportation Operations represent a significantly greater investment risk
than the Transportation Companies, and based on other information reviewed by
Houlihan Lokey, Houlihan Lokey estimated that an investor considering an
investment in the Transportation Operations would reasonably consider a
TIC/EBITDA multiple of 4.0, a TIC/EBIT multiple of 10.0, a TIC/DFCF multiple of
4.5 and a TIC/DFE multiple of 18.0.  Houlihan Lokey then multiplied each
multiple by such multiple's appropriate representative level to yield valuation
indications for the Transportation Operations.  Such computations yielded TIC
amounts of $7.7 million based on EBIT, $8.5 million based on EBITDA, $8.3
million based on DFE, and $8.2 million based on DFCF. Using the median of such
indications results in a total invested capital for the Transportation
Operations of approximately $8.2 million.

     In its discounted cash flow analysis, Houlihan Lokey determined the
enterprise value of the Transportation Operations by adding:  (i) the present
value of the five-year projected debt-free, net cash flow of the Transportation
Operations to (ii) the present value of the Transportation Operations' 2002
terminal value.  The projected cash flows for the years 1998 through 2002 were
based upon the financial projections provided by ASW's management.  Houlihan
Lokey discounted these cash flows at a rate of 15%.  The selected discount rate
reflects the rate of return Houlihan Likey estimates would be reasonably
required by providers of capital to the

     
                                       25
<PAGE>
    
 
Transportation Operations to compensate such providers for the time value of
their money, as well as the risk inherent in their investment. Houlihan Lokey
estimated the appropriate discount rate by examining similar investment
opportunities in the public market and attempting to determine the market
consensus expected returns for these investments. The terminal value was
determined by multiplying the Transportation Operations projected EBITDA for
fiscal 2002 by a multiple determined based on an analysis of the Transportation
Companies (4.0 times). Houlihan Lokey considered the terminal EBITDA multiple to
be reasonable for the reasons described in the previous paragraph. The present
value of the terminal value was then determined using the previously selected
discount rate of 15%. Houlihan Lokey then added the present value of the
terminal value to the present value of the aggregate projected cash flow for the
1998 through 2002 period to arrive at a total invested capital for the
Transportation Operations of approximately $7.0 million.

     Based upon the valuation indications of both the capitalization of earnings
and discounted cash flow approaches, Houlihan Lokey concluded that the total
invested capital for the Transportation Operations is reasonably stated in the
amount of $7.6 million, before consideration of corporate overhead allocations,
nonoperating assets and interest-bearing debt.

Technical Environmental Services Operations

     In the capitalization of earnings approach, Houlihan Lokey calculated
earnings levels which it considered to be representative of the future operating
performance of the Technical Operations.  Houlihan Lokey reviewed and compared
the financial, operating and market performance of the Technical Operations to
the following group of six companies selected from a review of various publicly
traded companies:  Ecology and Environment, Inc.;EMCON; Harding Lawson
Associates, Inc.; International Technology Corp.; Tetra Tech, Inc.; and TRC
Companies, Inc. (the "Technical Companies").  Houlihan Lokey examined certain
publicly available or estimated financial data of the Technical Companies,
including total revenue, total assets, EBIT, EBITDA, interest-bearing debt and
net income.  Houlihan Lokey also examined and compared various operating ratios
and certain capitalization data.  Houlihan Lokey also reviewed market data,
including various trading multiples such as stock price to earnings per share,
enterprise value to EBIT, enterprise value to EBITDA, enterprise value to DFE,
enterprise value to DFCF, and price ("P") to cash flow ("CF").  Houlihan Lokey
also considered other financial data (including margins and growth rates) as
well as certain operating information for the Technical Companies.  Based upon
Houlihan Lokey's review of this financial and other information, Houlihan Lokey
concluded that the Technical Operations represent a significantly greater
investment risk, for a given return, than the Technical Companies taken as a
group.

     Houlihan Lokey derived the capitalization rates for the Technical
Comparables by dividing the value of each comparable company's total invested
capital by the next fiscal year ended estimates, latest 12 months, and latest
fiscal year-end average, EBITDA, DFCF and CF.  The Technical Companies'
TIC/EBITDA multiples for the next fiscal year ranged from 2.5 to 7.6 with a
median of 4.2. P/CF and TIC/DFCF multiples for the next fiscal year ranged from
4.5 to 7.2 and 5.1 to 20.2, with medians of 6.9 and 10.0, respectively.  Based
on Houlihan Lokey's determination that the Technical Companies, and based on
other information reviewed by

     
                                       26
<PAGE>
     
Houlihan Lokey, Houlihan Lokey estimated that an investor considering an
investment in the Technical Operations would reasonably consider a TIC/EBITDA
multiple of 4.0, a P/CF multiple of 4.5 and a TIC/DFCF multiple of 5.0. Houlihan
Lokey then multiplied each multiple by such multiple's appropriate
representative level to yield valuation indications for the Technical
Operations. Such computations yielded TIC amounts of $5.0 million based on
EBITDA, $5.8 million based on P/CF, and $5.2 million based on DFCF. Using the
median of such indications results in at a total invested capital for the
Technical Operations of approximately $5.2 million.

     In its discounted cash flow analysis, Houlihan Lokey determined the
enterprise value of the Technical Operations by adding:  (i) the present value
of the five-year projected debt-free, net cash flow of the Technical Operations
to (ii) the present value of the Technical Operations' 2002 terminal value.  The
projected cash flows for the year 1998 through 2002 were based upon the
financial projections provided by AWS's management.  Houlihan Lokey discounted
these cash flows at a rate of 17%.  The selected discount rate reflects the rate
of return that Houlihan Lokey estimates would be reasonably required by
providers of capital to the Technical Operations to compensate such providers
for the time value of their money, as well as the risk inherent in their
investment.  Houlihan Lokey estimated the appropriate discount rate by examining
similar investment opportunities in the public market and attempting to
determine the market consensus expected returns for these investments.  The
terminal value was determined by multiplying the Technical Operations projected
EBITDA for fiscal 2002 by a multiple determined based on an analysis of the
Technical Companies (4.0 times).  Houlihan Lokey considered the terminal EBITDA
multiple to be reasonable for the reasons described in the previous paragraph.
The present value of the terminal value was then determined using the previously
selected discount rate of 17%.  Houlihan Lokey then added the present value of
the terminal value to the present value of the aggregate projected cash flow for
the 1998 through 2002 period to arrive at a total invested capital for the
Technical Operations of approximately $6.3 million.

     Based upon the valuation indications of both the capitalization of earnings
and discounted cash flow approaches, Houlihan Lokey concluded that the total
invested capital for the Technical Operations is reasonably stated in the amount
of $5.7 million, before consideration of corporate overhead allocations,
nonoperating assets and interest-bearing debt.

Waste Disposal Brokerage and Management Operations

     In the capitalization of earnings approach, Houlihan Lokey calculated
earnings levels which it considered to be representative of the future operating
performance of the Waste Disposal Operations.  Houlihan Lokey reviewed and
compared the financial, operating and market performance of the Waste Disposal
Operations to the following group of four companies selected from a review of
various publicly traded companies:  EMCON, Intrenet, Inc., KTI, Inc., and Trism,
Inc. (the "Waste Disposal Companies").  Houlihan Lokey examined certain publicly
available or estimated financial data of the Waste Disposal Companies, including
total revenue, total assets, EBIT, EBITDA, interest-bearing debt and net income.
Houlihan Lokey also examined and compared various operating ratios and certain
capitalization data.  Houlihan Lokey also reviewed market data, including
various trading multiples such as stock price to earnings per

     
                                       27
<PAGE>
     
share, enterprise value to EBIT, enterprise value to EBITDA, enterprise
value to DFE, enterprise value to DFCF, price to CF, and price to earnings
("E"). Houlihan Lokey also considered other financial data (including margins
and growth rates) as well as certain operating information for the Waste
Disposal Comparables. Based upon Houlihan Lokey's review of this financial and
other information, Houlihan Lokey concluded that the Waste Disposal Operations
represent a significantly greater investment risk, for a given return, than the
Waste Disposal Companies taken as a group.

     Houlihan Lokey derived the capitalization rates for the Waste Disposal
Companies by dividing the value of each company's total invested capital by the
next fiscal year ended estimates, latest 12 months, and latest fiscal year-end
average, EBITDA, EBIT, DFCF, DFE, E and CF.  The Waste Disposal Companies'
TIC/EBIT and TIC/EBITDA multiples for the next fiscal year ranged from 8.8 to
9.4 and from 4.2 to 7.2 with medians of 9.1 and 5.7, respectively.  TIC/DFE and
TIC/DFCF multiples for the next fiscal year ranged from 14.8 to 15.6 and 5.1 to
10.8, with medians of 15.2 and 8.0, respectively.  P/E and P/CF multiples for
the next fiscal year ranged from 12.8 to 16.1 and 4.5 to 8.4, with medians of
12.8 and 6.4, respectively.  Based on Houlihan Lokey's determination that the
Waste Disposal Operations represent a significantly greater investment risk than
the Waste Disposal Companies, and based on other information reviewed by
Houlihan Lokey, Houlihan Lokey estimated that an investor considering an
investment in the Waste Disposal Operations would reasonably consider a
TIC/EBITDA multiple of 4.0, a TIC/EBIT multiple of 4.0, a TIC/DFCF multiple of
6.5, a TIC/DFE multiple of 6.5, a P/E multiple of 6.5, and a P/CF multiple of
6.5.  Houlihan Lokey then multiplied each multiple by such multiple's
appropriate representative level to yield valuation indications for the Waste
Disposal Operations.  Such computations yielded TIC amounts of $2.8 million
based on EBIT, $2.8 million based on EBITDA, $2.7 million based on DFE, $2.7
million based on DFCF, $2.7 million  based on P/E, and $2.7 million based on
P/CF.  Using the median of such indications results in a total invested capital
for the Waste Disposal Operations of approximately $2.7 million.

     In its discounted cash flow analysis, Houlihan Lokey determined the
enterprise value of the Waste Disposal Operations by adding:  (i) the present
value of the five-year projected debt-free, net cash flow of the Waste Disposal
Operations to (ii) the present value of the Waste Disposal Operations' 2002
terminal value.  The projected cash flows for the years 1998 through 2002 were
based upon the financial projections provided by AWS's management.  Houlihan
Lokey discounted these cash flows at a rate of 16%.  The selected discount rate
reflects the rate of return that Houlihan Lokey estimates would be reasonably
required by providers of capital to the Waste Disposal Operations to compensate
such providers for the time value of their money, as well as the risk inherent
in their investment.  Houlihan Lokey estimated the appropriate discount rate by
examining similar investment opportunities in the public market and attempting
to determine the market consensus expected returns for these investments.  The
terminal value was determined by multiplying the Waste Disposal Operations
projected EBITDA for fiscal 2002 by a multiple determined based on an analysis
of the Waste Disposal Companies (4.0 times).  Houlihan Lokey considered the
terminal EBITDA multiple to be reasonable for the  reasons described in the
previous paragraph.  The present value of the terminal value was determined
using the previously selected discount rate of 16%.  Houlihan Lokey then added
the present value
     
                                       28
<PAGE>
     
of the terminal value to the present value of the aggregate projected cash flow
for the 1998 through 2002 period to arrive at a total invested capital for the
Waste Disposal Operations of approximately $3.4 million.

     Based upon the results of both the capitalization of earnings and
discounted cash flow approaches, Houlihan Lokey concluded that the total
invested capital for the Waste Disposal Operations is reasonably stated in the
amount of  $3,.1 million, before consideration of corporation overhead
allocations, nonoperating assets and interest-bearing debt.

Golf Course and Related Operations

     Owing to the lack of publicly traded comparables, Houlihan Lokey did not
utilize the capitalization of earnings approach for the Golf Course Operations.
In its discounted cash flow analysis, Houlihan Lokey determined the enterprise
value of the Golf Course Operations by adding:  (i) the present value of the
five-year projected debt-free, net cash flow of the Golf Course Operations to
(ii) the present value of the Golf Course Operations' 2002 terminal value.  The
projected cash flows for the years 1998 through 2002 were based upon the
financial projections provided by AWS's management.  Houlihan Lokey discounted
these cash flows at a rate of 13%.  The selected discount rate reflects the rate
of return that Houlihan Lokey estimates would be reasonably required by
providers of capital to the Golf Course Operations to compensate such providers
for the time value of their money, as well as the risk inherent in their
investment.  Houlihan Lokey estimated the appropriate discount rate by examining
similar investment opportunities in the public market and attempting to
determine the market consensus expected returns for these investments.  The
terminal value was determined by multiplying the Golf Course Operations
projected EBITDA for fiscal 2002 by a multiple determined based on an analysis
of similar investment risks (6.0 times).  The present value of the terminal
value was then determined using the previously selected discount rate of 13%.
Houlihan Lokey then added the present value of the terminal value to the present
value of the aggregate projected cash flow for the 1998 through 2002 period to
arrive at the total invested capital for the Golf Course Operations of
approximately $3.6 million, before consideration of corporate overhead
allocations, non-operating assets and interest-bearing debt.


Valuation Summary and Conclusion

     Based on the foregoing analysis concerning each of the four, Houlihan Lokey
determined that the aggregate value of the operations, before consideration of
corporate overhead allocations, nonoperating assets and interest-bearing debt,
was approximately $20.0 million.  Houlihan Lokey made certain adjustments to
this value to determine the value of the Avalon Common Stock.  Avalon has
projected corporate charges, excluding depreciation expense, for 1998 of
approximately $1.9 million.  Capitalizing this figure at a rate of 4.0 times
yields an offset to value for corporate charges of $7.9 million.  Subtracting
this figure from the unadjusted value of the operations yields a value of $12.1
million.  With respect to Avalon's cash balance on March 31, 1998, Avalon
management certified that Avalon's cash balance as of the Spin-off will be
approximately $20,000,000.  Adding Avalon's estimated cash balance of
$20,000,000 and
     
                                       29
<PAGE>
     
subtracting total interest-bearing debt of $1.2 million yielded a fair market
value of Avalon Common Stock of $30,425,160, which approximates $1.00 per share
of AWS Common Stock, based upon 25,300,608 shares of AWS Class A Common Stock
and 5,124,558 shares of Class B Common Stock outstanding. After adjusting for
the dividend of one share of Avalon Common Stock for each eight shares of AWS
Common Stock held, the total fair market value of Avalon Common Stock equates to
$8.00 per share of Avalon Common Stock based on 3,162,576 shares of Avalon Class
A Common Stock and 640,569 shares of Avalon Class B Common Stock outstanding
after the Spin-off. No "control premium" is reflected in this valuation.
     

     The Opinion was based on business, economic, market and other conditions
that existed and that could be evaluated by Houlihan Lokey as of March 31, 1998.
The Opinion does not address AWS's underlying business decision to effect the
Transactions.  The Opinion does not constitute a "fairness" opinion and
stockholders of AWS should not rely on the Opinion as an indication that the
Transactions are fair from a financial point of view.  Houlihan Lokey was not
requested to, and did not, solicit third party indications of interest in
acquiring all or any part of Avalon.


    
     The full text of the Opinion, which sets forth the assumptions made,
general procedures followed, factors considered and limitations on the review
undertaken by Houlihan Lokey in rendering the Opinion, is attached as Appendix A
hereto.  Houlihan Lokey has consented to the inclusion of the Opinion as
Appendix A and to the inclusion of the summary thereof herein.  In giving such
consent, Houlihan Lokey does not admit that it comes within the category of
persons whose consent is required under Section 7 of the Securities Act, or the
rules and regulations promulgated thereunder, nor does it thereby admit that it
is an expert with respect to any part of the Registration Statement in which
this Proxy Statement is a part within the meaning of the term "experts" as used
in the Securities Act or the rules and regulations promulgated thereunder.  The
summary of the Opinion set forth herein is qualified in its entirety by
reference to the full text of the Opinion.  Holders of AWS Common Stock are
urged to read the Opinion carefully and in its entirety.

     AWS has paid Houlihan Lokey a fee of $125,000 for its services in
connection with the Opinion.  This fee was required to be paid whether or not
the Transactions are consummated.  AWS also agreed to reimburse Houlihan Lokey
for its out-of-pocket expenses and to indemnify Houlihan Lokey against certain
claims and liabilities, including liabilities under the federal securities laws,
that may arise in connection with the Transactions.  Other than as set forth in
this Proxy Statement, to the knowledge of AWS, no material relationships between
Houlihan Lokey or any of its affiliates and AWS or any of its affiliates exist,
have existed during the past two years or are contemplated.

     Stockholders are advised that any determination of Houlihan Lokey should
not be used or relied upon other than as set forth herein. The purpose for which
AWS retained Houlihan Lokey to render the Opinion was to determine the amount of
any taxable gain resulting from the Spin-off.  Although Stockholders of AWS may
consider the Opinion when voting on the Proposals, Stockholders of AWS should
not rely on the Opinion as an indication of the prices at which shares of Avalon
Class A Common Stock may actually

     
                                       30
<PAGE>
     
trade after the Spin-off. The prices at which shares of Avalon Class A Common
Stock actually trade may not have any relationship to the determination of
Houlihan Lokey. See "Risk Factors--Risk Factors Regarding the Spin-off--Listing
and Trading of Avalon Class A Common Stock; No Prior Public Market" and "Certain
Federal Income Tax consequences of the Transactions to AWS and its
Stockholders--The Spin-off."
     

                                THE TRANSACTIONS

     The following discussion summarizes the material aspects of the proposed
Transactions, which will be consummated in accordance with the terms of the
Distribution Agreement, the Merger Agreement and the other agreements described
in this Proxy Statement that are being executed in connection with the
Transactions.

The Spin-Off and the Distribution Agreement

     The following summary of the terms of the Distribution Agreement and of the
Spin-off is qualified in its entirety by reference to the Distribution
Agreement, a copy of which is attached hereto as Appendix C.  All stockholders
are urged to read the Distribution Agreement in its entirety.

     AWS through its subsidiaries owns and operates nonhazardous solid waste
landfills; transports hazardous and nonhazardous waste; provides transportation
and disposal brokerage and management services; provides refuse collection
services; provides technical environmental services, including environmental
engineering, site assessment, analytical laboratory and remediation services; is
a common carrier of general and bulk commodities; and operates a golf course and
related operations (collectively, the "AWS Businesses").  AWS and USA Waste have
agreed that, at the effective time of the Merger, the only AWS Businesses that
AWS will have will be the nonhazardous solid waste landfills it owns, the refuse
collection services it provides and its landfill gas collection and sales
business (the "Retained Businesses").  Consequently, AWS has agreed with USA
Waste to dispose of all of the other AWS Businesses (i.e., the Avalon Business)
and all of its other assets, properties and rights that USA Waste does not need
in order to operate the Retained Businesses (the "Nonessential Assets" and,
together with the assets, properties and rights of the Avalon Business, the
"Contributed Assets").

Contribution

     Upon the terms and subject to the conditions set forth in the Distribution

Assumption of Liabilities

     Upon the terms and subject to the conditions set forth in the Distribution
Agreement, on the Transactions Record Date, Avalon and AWS will execute an
assumption agreement whereby Avalon will assume and agree to perform, pay,
satisfy or discharge, when due, to the extent not theretofore performed, paid,
satisfied or discharged, (a) the debts, obligations, liabilities and commitments
of any nature, whether absolute or contingent, monetary or non-monetary, direct
or indirect, known or unknown, matured or unmatured ("Liabilities") of AWS
arising out of or related to the Contributed Assets; (b) the Liabilities,  if
any, of AWS arising out of or related to the action entitled Werbowsky vs.
                                                             -------------
American Waste Services, Inc., et al.; (c) contractual obligations related to
- -----------------------------------                                          
the sponsorship of the LPGA Golf Tournament at Avalon Lakes Golf Course; and (d)
certain other Liabilities described below (collectively, the "Assumed
Liabilities").  The liability of Avalon or any of its subsidiaries for any taxes
incurred or accrued prior to the Transactions Record Date is governed by the Tax
Allocation Agreement (as hereinafter defined).

     Except for the Assumed Liabilities, Avalon will not assume or in any way
undertake to pay, perform, satisfy or discharge any other Liability of AWS or
any Retained Subsidiary, and AWS or the applicable Retained Subsidiary will
perform, pay, satisfy and discharge all such Liabilities other than Assumed
Liabilities (the "Retained Liabilities").

Employment Matters

     From and after the Transactions Record Date, Avalon will assume and pay any
Liability (i) arising out of workers' compensation claims by all employees of
the Contributed Subsidiaries and Avalon (the "Avalon Employees") and all
employees of AWS and the Retained Subsidiaries  (a) whose employment is
terminated by AWS or the applicable Retained Subsidiary within two business days
after the Transactions Record Date or (b) whose employment is terminated by AWS
or the applicable Retained Subsidiary within 60 days after the Transactions
Record Date and whose name was on a list provided to AWS by USA Waste no later
than 30 days prior to the

                                       33
<PAGE>
 
date of the Special Meeting (the "Terminated Employees") unless the claim
relates to a Terminated Employee and is based solely on an occurrence after the
Transaction Records Date; or (ii) arising out of or related to the termination
of employment of any Avalon Employee or Terminated Employee; provided, however,
that Avalon will not assume or pay any Liability arising out of or related to
the termination of employment of any Terminated Employee who immediately prior
to the Transactions Record Date was an employee of American Landfill, Inc.,
American Landfill Gas Company, East Liverpool Landfill, Inc., Mahoning Landfill,
Inc. or SLF Development, Inc., to the extent that such Liability arises out of
an allegation that such termination was in violation of applicable law (as
opposed to being in breach of any agreement).

     From and after the Transactions Record Date, AWS and the Retained
Subsidiaries will pay any Liability arising out of or related to the employment
relations between any of them and any employee of AWS or a Retained Subsidiary
who is not an Avalon Employee or a Terminated Employee or any former employee of
any Retained Subsidiary or AWS who is not a Terminated Employee and not an
Avalon Employee.  From and after the Transactions Record Date, Avalon and the
Contributed Subsidiaries will pay any liability arising out of or relating to
the employment relations between any of them and their respective employees.

Insurance

     On or before the Transactions Record Date, AWS will transfer and assign to
Avalon all of AWS's insurance policies, other than the directors' and officers'
indemnification insurance.  If any such policy by its terms may not be assigned,
it is the intent of the parties that Avalon receive the benefit of any coverage
under any such insurance policy.  AWS, at Avalon's expense, will keep such
policy in effect during the remaining term of the policy and refrain from taking
any actions (other than making a claim) which may affect Avalon's entitlement to
the benefits of, or coverage under, such policy.  With respect to any such
policies, AWS will seek to have Avalon and its subsidiaries named as insureds
with respect to occurrences prior to the Transactions Record Date at Avalon's
expense, if requested to do so by Avalon.  AWS will receive, to the extent such
benefits may be available, the benefit of all insurance policies of AWS existing
prior to the Transactions Record Date to the extent such insurance covers
Retained Liabilities, and the parties will enter into commercially reasonable
arrangements to effect the provisions described in this sentence.

Distribution

     Following the Contribution, AWS will distribute in the form of a special
dividend all of the outstanding shares of capital stock of Avalon to the holders
of AWS Common Stock on a pro rata and corresponding basis.  Holders of AWS Class
A Common Stock will receive one share of Avalon Class A Common Stock for every
eight shares of AWS Class A Common Stock held on the Transactions Record Date,
and holders of AWS Class B Common Stock will receive one share of Avalon Class B
Common Stock for every eight shares of AWS Class B Common Stock held on the
Transactions Record Date, subject in each case to adjustment for fractional
shares.

                                       34
<PAGE>
 
     No fractional shares of Avalon Common Stock will be distributed in the
Spin-off.  Any fractional share that would otherwise be distributed will be
repurchased by Avalon as of the Transactions Record Date at a price based on the
valuation of Avalon by Houlihan Lokey.  Such cash will be distributed in the
Spin-off to the record holder of AWS Common Stock who would otherwise have been
entitled to receive such fractional share.  See "Background and Reasons--
Valuation of Avalon" and "Certain Federal Income Tax Consequences of the
Transactions to AWS and its Stockholders."

     It is expected that the shares of Avalon Class A Common Stock distributed
in the Spin-off will be listed on the American Stock Exchange under the symbol
"AWX."
    
     Based upon 25,301,308 shares of AWS Class A Common Stock and 5,123,858
shares of AWS Class B Common Stock outstanding on May 11, 1998, approximately
3,162,663 shares of Avalon Class A Common Stock and 640,482 shares of Avalon
Class B Common Stock will be distributed.  The shares of Avalon Common Stock to
be distributed will constitute all of the shares of Avalon Common Stock
outstanding immediately after the Spin-off.  AWS will have no ownership interest
in Avalon after the Spin-off, and Avalon will be an independent, publicly traded
company, owning the Avalon Business and Nonessential Assets.  The number and
identity of the stockholders of Avalon immediately after the Spin-off will be
substantially the same as the number and identity of the stockholders of AWS on
the Transactions Record Date.  The Spin-off will not itself affect the number of
outstanding shares of AWS Common Stock or any rights of holders of AWS Common
Stock.  See "Summary of Selected Historical and Pro Forma Financial Data of the
Avalon Business," "Capitalization of Avalon" and "Relationship and Arrangements
between AWS and Avalon."  See also the Historical Combined Financial Statements
of the Avalon Business of American Waste Services, Inc. and notes thereto and
the Unaudited Pro Forma Combined Financial Information and notes thereto
included elsewhere herein.
     
Indemnification

     Pursuant to the terms of the Distribution Agreement, Avalon will indemnify
and hold harmless USA Waste and AWS and each of their subsidiaries and their
respective officers, directors, employees, agents, successors and assigns
against every Loss relating to (i) any Assumed Liability; or (ii) the breach of
any covenant or agreement of Avalon pursuant to the Distribution Agreement.
Furthermore, pursuant to the terms of the Distribution Agreement, AWS will
indemnify and hold harmless Avalon and each of its subsidiaries and their
respective officers, directors, employees, agents, successors and assigns
against every Loss relating to (i) any Retained Liability; or (ii) the breach of
any covenant or agreement of AWS or USA Waste pursuant to the Distribution
Agreement.

Mutual Releases

     On the Transactions Record Date , each of AWS and Avalon will release any
and all claims that such party may have against the other party as of the
Transactions Record Date, other than claims (a) arising under the Distribution
Agreement and from the transactions contemplated thereby; (b) arising under the
Subcontract Agreements; and (c) intercompany payables reflected

                                       35
<PAGE>
 
on their respective financial statements and those thereafter incurred in the
ordinary course of business. The Subcontract Agreements are all contracts and
agreements (and outstanding bids and quotations, which if accepted, would fit in
the description set forth in this sentence) pursuant to which (i) one of the
Retained Subsidiaries or AWS is a party and under which one of the Contributed
Subsidiaries directly or indirectly (e.g., by rendering services or providing
                                     ----                                    
products to a Retained Subsidiary or AWS which are then used by such Retained
Subsidiary or AWS to render services or provide products or disposal space to a
third party) renders services or provides products or disposal space to the
third party who is a party thereto or (ii) one of the Contributed Subsidiaries
is a party and under which one of the Retained Subsidiaries or AWS directly or
indirectly (e.g., by rendering services or providing products or disposal space
            ----                                                               
to a Contributed Subsidiary which are then used by such Contributed Subsidiary
to render services or provide products or disposal space to a third party)
renders services or provides products or disposal space to the third party who
is a party thereto entered into or made in the ordinary course of business prior
to the Transactions Record Date.

The Merger and the Merger Agreement

     The following summary of the terms of the Merger Agreement is qualified in
its entirety by reference to the Merger Agreement, a copy of which is attached
hereto as Appendix B.  All stockholders are urged to read the Merger Agreement
in its entirety.

     Upon the terms and subject to the conditions set forth in the Merger
Agreement, on the Closing Date, in accordance with the Ohio General Corporation
Law (the "OGCL"), C&S Ohio Corp., a wholly owned subsidiary of USA Waste, will
be merged with and into AWS and the separate existence of C&S Ohio Corp. will
thereupon cease.  AWS will be the surviving corporation in the Merger and become
a wholly owned subsidiary of USA Waste.

Closing Date of the Merger

     The date the Merger will occur (the "Closing Date") will be no more than 15
business days after the date on which all the conditions set forth in the Merger
Agreement have been satisfied or waived or such other date as the parties to the
Merger Agreement may agree.  The Spin-off will be effected after the close of
business on the day before the Closing Date.  The record date for both the Spin-
off and the Merger will be the close of business on the day before the Closing
Date (the "Transactions Record Date").  There can be no assurance, however, as
to whether or when the Transactions will be consummated.  See "--Conditions to
the Merger."

     The Merger will become effective at the time stated in the certificate
filed with the Secretary of State of the State of Ohio in accordance with the
OGCL (the "Merger Filing"). The Merger Filing will be made simultaneously with,
or as soon as practicable after, the closing of the transactions contemplated by
the Merger Agreement.

                                       36
<PAGE>
 
Manner and Basis for Converting Shares

     On the Closing Date, each outstanding share of AWS Common Stock will,
subject to applicable law, be converted into the right to receive, without
interest, cash in an amount equal to $4.00 per share.  Prior to the Closing
Date, USA Waste will deposit in trust with a paying agent (the "Paying Agent")
an amount equal to $4.00 multiplied by the number of outstanding shares of AWS
Common Stock.  As soon as reasonably practicable after the Closing Date, the
Paying Agent will mail to each holder of record of AWS Common Stock as of the
Transactions Record Date a letter of transmittal containing, among other things,
notification of the effectiveness of the Merger and instructions for effecting
the surrender and exchange of certificates formerly representing shares of AWS
Common Stock for the $4.00 per share cash consideration (less the amount of any
withholding taxes which may be required to be withheld).

     The Paying Agent will be entitled to deduct and withhold from the
consideration otherwise payable to any holder of shares of AWS Common Stock such
amounts as may be required to be deducted and withheld with respect to the
making of such payment under any provision of Federal, state, local or foreign
tax law.  To the extent that amounts are so withheld and paid over to the
appropriate taxing authority, such withheld amounts will be treated as having
been paid to the holder of the shares of AWS Common Stock in respect of which
such withholding was made.

     After the Closing Date, the stock transfer books of AWS will be closed.
Share certificates should not be surrendered for cash by stockholders of AWS
prior to approval of the Proposals and the receipt of a letter of transmittal
from the Paying Agent.

AWS Options

     The Merger Agreement provides that, prior to the Closing Date, AWS will use
its reasonable best efforts to redeem all unexpired and unexercised options to
purchase shares of AWS Common Stock (the "AWS Options").

     With respect to any AWS Options that would be held by Avalon Employees
after the Closing Date ("Avalon Employee Options"), to the extent that any such
Avalon Employee Options have not been redeemed prior to the Closing Date, AWS
and USA Waste will take such action as may be legally permissible to cause each
such Avalon Employee Option to be automatically converted on the Closing Date
into an option (each, an "Avalon Option") to purchase shares of Avalon Common
Stock.  Avalon will assume all of AWS's obligations with respect to such Avalon
Employee Options as so amended and will, from and after the Closing Date, make
available for issuance upon exercise of any Avalon Options the shares of Avalon
Common Stock covered thereby and will file a registration statement on Form S-8
to cover the shares of Avalon Common Stock subject to those options.

     Each AWS Option that has not been redeemed by AWS or converted into an
Avalon Option, whether or not then exercisable, will be automatically converted
by virtue of the Merger into an option to purchase shares of USA Waste common
stock.

                                       37

Pre-Closing Financial Transactions

Primary USA Loan

     Subject to certain limitations discussed below, USA Waste will, immediately
prior to the Contribution, lend to AWS, pursuant to a promissory note in a form
to be agreed upon by AWS and USA Waste, an amount equal to (a) $150,000,000
minus (b) the product of $4.00 and the number of shares of AWS Common Stock
outstanding as of such time (the "Primary USA Loan").  AWS will use the funds
from the Primary USA Loan as follows:

     First, AWS will use those funds to pay or cause to be paid the following
obligations (collectively, the "Transaction Liabilities") of AWS and the
Retained Subsidiaries determined as of the Transactions Record Date: (i) the
transaction costs incurred by AWS in connection with the Merger, the
Contribution and the Spin-off; (ii) the amount required to redeem the AWS
Options being redeemed; and (iii) the amount outstanding under AWS's existing
revolving credit facility (the "Credit Facility") as of December 31, 1997, plus
any amounts borrowed thereunder after December 31, 1997, the proceeds of which
were not used for a purpose primarily attributable to any Retained Subsidiary,
plus accrued but unpaid interest thereon from December 31, 1997.

     Second, after having made the above payments, AWS will reserve an amount to
pay any Distribution Tax (as hereinafter defined) when due.

     Third, AWS will calculate the remaining funds available from the Primary
USA Loan (the "Remaining Funds") and then will calculate the sum of the
obligations owed by any Retained Subsidiary to AWS (which will be treated as
positive numbers) and the intercompany obligations owed by AWS to any Retained
Subsidiary (which will be treated as negative numbers).  Such sum is the "Net
Intercompany Receivables."  If the Remaining Funds are greater than or equal to
the sum of (x) the Net Intercompany Receivables, (y) the long-term debt owed by
Mahoning Landfill, Inc. to AWS (the "MLI Debt"), and (z) any Retained Stock
Option Liability (as hereinafter defined) (which will be treated as a positive
number), then an amount equal to the Net Intercompany Receivables will be deemed
contributed to Avalon under the Distribution Agreement as "Contributed Net
Intercompany Receivables" for purposes of any Net Working Capital Adjustment (as
hereinafter defined).  If the Remaining Funds are less than such sum, then only
such amount of such intercompany obligations owed to AWS equal to the excess of
the Remaining Funds over the MLI Debt and any Retained Stock Option Liability
will be deemed contributed to Avalon under the Distribution Agreement as
"Contributed Net Intercompany Receivables" for purposes of any Net Working
Capital Adjustment.

Contribution of Net Intercompany Receivables

     Subject to certain limitations discussed below, following the final
determination of Contributed Net Intercompany Receivables, and following the
payment of the Transaction Liabilities by AWS and the reservation for any
Distribution Tax, AWS will contribute the Contributed Net Intercompany
Receivables and the MLI Debt to Avalon and will contribute sufficient amounts of
Remaining Funds to the appropriate Retained Subsidiaries for and will

                                       38
<PAGE>
 
cause such Retained Subsidiaries to pay Avalon for the Contributed Net
Intercompany Receivables and the MLI Debt.

Net Working Capital Adjustment

     Following the adjustments discussed above, a pro forma consolidated balance
sheet of AWS and the Retained Subsidiaries is to be generated and the "Net
Working Capital" is to be calculated by subtracting (a) the current liabilities
(which will include the water-line liability of Mahoning Landfill Inc., which is
deemed to be equal to $750,000) from (b) the current assets on such balance
sheet.  For purposes of the foregoing calculation, the full amount of the
Primary USA Loan will be deemed to be a long-term liability.  If the Net Working
Capital so calculated is a positive number, then USA Waste will make a
"Secondary USA Loan" in an amount sufficient for AWS to make, and AWS will make,
an additional cash contribution to Avalon in an amount equal to the Net Working
Capital as part of the Contribution.  If the Net Working Capital so calculated
is a negative number, then the amount of Contributed Net Intercompany
Receivables to be contributed by AWS to Avalon will be reduced by such number
(the "Net Working Capital Deficiency").  Such additional payment or reduction,
as the case may be, is the "Net Working Capital Adjustment."

Retained Stock Option Adjustment

     To the extent that outstanding AWS Options have not been redeemed by AWS or
converted into Avalon Employee Options, then an aggregate amount equal to the
sum of (i) the difference between $4.00 and the exercise price of each such AWS
Option, (ii) multiplied by the number of shares of AWS Common Stock for which
such AWS Option is exercisable ("Retained Stock Option Liability") for all such
AWS Options will be calculated.  If the exercise price of any AWS Option exceeds
$4.00, then the Retained Stock Option Liability with respect to such option will
equal the product of $1.00 and the number of shares of AWS Common Stock for
which such AWS Option is exercisable.

Distribution Tax

     Prior to the Closing Date, the parties will calculate the federal, state
and local income, sales, transfer and other taxes (the "Distribution Tax") which
may be incurred by AWS on the taxable gain, if any, recognized on the Spin-off.
In calculating the Distribution Tax, USA Waste and AWS agree to abide by the
opinion (the "Valuation") of Houlihan Lokey as to the fair market value of
Avalon as of the Transactions Record Date.  After Houlihan Lokey has delivered
the Valuation to USA Waste and AWS, AWS will calculate the taxable gain, if any,
to AWS resulting from the Spin-off and the resulting federal, state and local
income, sales, transfer and other taxes thereon, using AWS's adjusted tax basis
in the outstanding shares of Avalon Common Stock as of the Transactions Record
Date.  The Merger Agreement provides USA Waste with a mechanism to review the
calculation of the Distribution Tax and dispute such tax.

Limitations

     Notwithstanding anything in the Merger Agreement to the contrary, if the
sum of the Transaction Liabilities, the Distribution Tax, the Net Working
Capital Deficiency and the aggregate Retained Stock Option Liability is greater
than the amount of the Primary USA Loan, then USA Waste will not be obligated to
consummate the Merger and will be entitled to

                                       39
<PAGE>
 
terminate the Merger Agreement and, if USA Waste terminates the Merger
Agreement, it will have no obligation to make the Primary USA Loan or the
Secondary USA Loan.

Conditions to the Merger

     The respective obligations of USA Waste and AWS to effect the Merger are
subject to the fulfillment on or prior to the Closing Date of the following
conditions:  (a) the Merger Agreement and the transactions contemplated thereby
having been approved and adopted by the requisite vote of the stockholders of
AWS under applicable law; (b) the waiting period applicable to the consummation
of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as

(d) the Distribution Tax having been determined in accordance with the Merger
Agreement; (e) no preliminary or permanent injunction or other order or decree
by any federal or state court which prevents the consummation of the Merger
having been issued and remaining in effect; and (f) no statute, rule or
regulation having been enacted by any state or federal government or
governmental agency in the United States which would prevent the consummation of
the Merger or make the consummation of the Merger illegal.

fulfillment on or prior to the Closing Date of the following additional
conditions:  USA Waste having performed its agreements contained in the Merger
Agreement required to be performed on or prior to the Closing Date, and the
representations and warranties of USA Waste contained in the Merger Agreement

perform or to be true and correct that would not reasonably be expected to have
a material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of USA Waste and its
subsidiaries considered as a whole.

     The obligations of USA Waste and C&S Ohio Corp. to effect the Merger are
also subject to the fulfillment on or prior to the Closing Date of the following
additional conditions: (i) AWS having performed its agreements contained in the
Merger Agreement required to be performed on or prior to the Closing Date, and

a material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of AWS and its
subsidiaries considered as a whole; (ii) since February 6, 1998 there having

operations, properties, assets, liabilities, condition (financial or other) or
results of operations of AWS and the Retained Subsidiaries, taken as a whole,
except for changes that affect the industries in which AWS and the Retained
Subsidiaries operate generally or volume reductions to the extent arising from
business decisions made by

                                       40

existing or potential customers; (iii) all governmental waivers, consents,
orders and approvals legally required for the consummation of the Merger and the
other transactions contemplated by the Merger Agreement having been obtained and

liabilities, condition (financial or other) or results of operations of AWS and
its subsidiaries, taken as a whole; (iv) no more than ten percent of the
outstanding shares of AWS Common Stock being held by stockholders who have

     Subject to the terms and conditions in the Merger Agreement and subject to
the fiduciary duties of the respective boards of directors of AWS and USA Waste,
each of the parties has agreed to use commercially reasonable efforts to take,
or cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by the Merger
Agreement, including using reasonable efforts to obtain all necessary or
appropriate waivers, consents or approvals of third parties required in order to
preserve material contractual relationships of AWS and its Retained Subsidiaries
and all necessary or appropriate waivers, consents and approvals and "no-action"
letters from the SEC and to effect all necessary registrations, filings and
submissions and to lift any injunction or other legal bar to the Merger.  In
accordance with the Merger Agreement, each of USA Waste and AWS filed on
February 17, 1998 a Notification and Report Form under the HSR Act with the
Federal Trade Commission ("FTC") and the Antitrust Division of the Department of
Justice (the "Antitrust Division").  On March 13, 1998, each of AWS and USA
Waste was informed that the FTC had granted early termination of the waiting
period under the HSR Act.  Each of USA Waste and AWS will (i) respond as
promptly as practicable to all inquiries and requests received from any State
Attorney General or other governmental authority in connection with antitrust
matters; and (ii) not enter into any agreement with the FTC or the Antitrust
Division not to consummate the transactions contemplated by the Merger
Agreement, except with the prior written consent of the other parties thereto.
In addition, in the event any litigation is commenced by any person or entity
relating to the transactions contemplated by the Merger Agreement, including an
Acquisition Transaction (as hereinafter defined), USA Waste will have the right,
at its own expense, to participate therein, and AWS will not settle any such
litigation without the consent of USA Waste, which consent will not be
unreasonably withheld.

consummation of the transactions under the Merger Agreement to allow USA Waste
or AWS as the surviving corporation in the Merger to conduct the business of AWS
and the Retained Subsidiaries as currently conducted.

No Solicitation of Acquisition Transactions

     The Merger Agreement provides that after February 6, 1998 and prior to the
Closing Date or earlier termination of the Merger Agreement, AWS will not, and
will not permit any of its subsidiaries to, initiate, solicit, negotiate,
encourage or provide confidential information to facilitate, and AWS will, and
will cause each of its subsidiaries to, cause any officer, director or employee
of it, or any attorney, accountant, investment banker, financial advisor or
other agent retained by it, not to initiate, solicit, negotiate, encourage or
provide non-public or confidential

                                       43
<PAGE>
 
information to facilitate, any proposal or offer (each, an "Acquisition
Proposal") to acquire all or any substantial part of the business and properties
of AWS or any capital stock of AWS (each, an "Acquisition Transaction"), whether
by merger, purchase of assets, tender offer or otherwise, whether for cash,
securities or any other consideration or combination thereof. Notwithstanding
the above-described provisions and without being a breach or violation thereof:
(a) AWS may, in response to an unsolicited Acquisition Proposal furnish (subject
to the execution of a confidentiality agreement substantially similar to the
confidentiality provisions of the confidentiality agreement executed by USA
Waste in connection with the Merger Agreement (the "Confidentiality Agreement"))
confidential or non-public information concerning its business, properties or
assets to a potential acquiror and negotiate with such potential acquiror if (i)
the AWS Board in good faith determines that such Acquisition Proposal (if
consummated pursuant to its terms) would result in a transaction more favorable
to AWS's stockholders than the Merger and (ii) based upon advice of its outside
legal counsel, the AWS Board determines in good faith that the failure to
provide such confidential or non-public information to such potential acquiror
would be reasonably likely to constitute a breach of its fiduciary duty to its
stockholders (a "Superior Proposal"); and (b) the AWS Board may take and
disclose to AWS's stockholders a position with respect to a tender offer by a
third party pursuant to Rules 14d-9 and 14e-2(a) under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), or may make such other disclosures
to AWS's stockholders which, as advised by outside counsel, are required under
applicable law. The Merger Agreement requires AWS to immediately notify USA
Waste after receipt of any Acquisition Proposal or any request for non-public
information relating to AWS or its subsidiaries in connection with an
Acquisition Proposal or for access to the properties, books or records of AWS or
any subsidiary by any person or entity that informs the AWS Board or such
subsidiary that it is considering making, or has made, an Acquisition Proposal.
Such notice to USA Waste will be made orally and in writing and will indicate in
reasonable detail the identity of the offeror and the terms and conditions of
such proposal, inquiry or contact.

Termination or Amendment

     The Merger Agreement may be terminated at any time prior to the Closing
Date, whether before or after approval and adoption by the stockholders of AWS,
by the mutual written consent of AWS and USA Waste.  In addition, the Merger
Agreement may be terminated (a) by AWS (i) if any of the representations and
warranties of USA Waste fails to be true and correct and such failure will cause
certain conditions set forth in the Merger Agreement to be incapable of being
satisfied by July 31, 1998 (the "Termination Date") and such failure has not
been cured in all material respects within 30 days after notice of such breach
is given to USA Waste by AWS; (ii) if the Merger is not completed by the
Termination Date; provided, that the right to terminate the Merger Agreement
pursuant to the provisions described in this clause will not be available to AWS
(x) if the failure of AWS to fulfill any obligation to USA Waste under or in
connection with the Merger Agreement has been the cause of or resulted in the
failure of the Merger to occur on or before such date or (y) if AWS is at such
time exercising its rights under the Merger Agreement with respect to a Superior
Proposal; (iii) if the Merger is enjoined by a final, unappealable court order;
(iv) if the requisite votes of the stockholders of AWS have not been obtained at
the Special Meeting; (v) if USA Waste (x) fails to perform in any material
respect

                                       44
<PAGE>
 
any of its material covenants in the Merger Agreement and (y) does not cure such
default in all material respects within 30 days after notice of such default is
given to USA Waste by AWS; (vi) if (x) AWS receives a Superior Proposal from any
third party, (y) the AWS Board resolves to accept such Superior Proposal, and
(z) AWS has given USA Waste two days' prior written notice of its intention to
terminate the Merger Agreement pursuant to the provisions described in this
clause; (vii) if (x) a tender or exchange offer is commenced by a third party
for all outstanding shares of AWS Common Stock, (y) the AWS Board determines in
good faith that such offer constitutes a Superior Proposal and resolves to
accept such Superior Proposal or recommend to the AWS stockholders that they
tender their shares in such tender or exchange offer, and (z) AWS has given USA
Waste two days' prior written notice of its intention to terminate the Merger
Agreement pursuant to the provisions described in this clause; or (viii) if the
Distribution Agreement or the Tax Allocation Agreement has been terminated in
accordance with its respective terms; and (b) by USA Waste (i) if any of the
representations and warranties of AWS fails to be true and correct and such
failure will cause certain conditions set forth in the Merger Agreement to be
incapable of being satisfied by the Termination Date and such failure has not
been cured in all material respects within 30 days after notice of such breach
is given to AWS by USA Waste; (ii) if the Merger is not completed by the
Termination Date; provided, that the right to terminate the Merger Agreement
pursuant to the provisions described in this clause will not be available to USA
Waste if the failure of USA Waste to fulfill any obligation to AWS under or in
connection with the Merger Agreement has been the cause of or resulted in the
failure of the Merger to occur on or before such date; (iii) if AWS (x) fails to
perform in any material respect any of its material covenants in the Merger
Agreement and (y) does not cure such default in all material respects within 30
days after written notice of such default is given to AWS by USA Waste; (iv) if
the AWS Board resolves to accept a Superior Proposal or has recommended to the
stockholders of AWS that they tender their shares in a tender or exchange offer
commenced by a third party; (v) if the requisite votes of the stockholders of
AWS have not been obtained at the Special Meeting; (vi) if the Merger is
enjoined by a final, unappealable court order; or (vii) if the Distribution
Agreement or the Tax Allocation Agreement has been terminated in accordance with
its respective terms.

     In the event of termination of the Merger Agreement pursuant to its terms
by either USA Waste or AWS, the Merger Agreement will forthwith become void and
there will no further obligations on the part of AWS, USA Waste or their
respective officers and directors (except for certain specified obligations set
forth in the Merger Agreement and the Confidentiality Agreement, which will
survive such termination and relate primarily either to maintaining
confidentiality or paying the termination fees described below).

     The Merger Agreement may not be amended except by action taken by the
parties' respective boards of directors or duly authorized committees thereof,
and then only by an instrument in writing signed on behalf of each party and in
compliance with applicable law.

Termination Fees

     Pursuant to the Merger Agreement, AWS has agreed to pay USA Waste a fee
equal to $7,500,000 if (a) AWS terminates the Merger Agreement pursuant to the
provisions described in

                                       45
<PAGE>
 
clause (a)(vi) or (a)(vii) under "--Termination or Amendment" above; (b) USA
Waste terminates the Merger Agreement pursuant to the provisions described in
clause (b)(iv) under "--Termination or Amendment" above; or (c) AWS terminates
the Merger Agreement pursuant to the provisions described in clause (a)(iv) or
USA Waste terminates the Merger Agreement pursuant to the provisions described
in clause (b)(v) under "--Termination or Amendment" above and within seven
months of such termination AWS enters into an agreement for, or a letter of
intent with respect to, an Acquisition Transaction with a per share
consideration for the AWS Common Stock greater than the sum of $4.00 plus the
per share value of the Spin-off (as calculated from the Valuation); provided,
however, that the payment of the fee payable pursuant to the provisions
described in this clause (c) need not be made unless and until the consummation
of such Acquisition Transaction. For purposes of the provisions described in
clause (c) of the preceding sentence, the per share consideration for an
Acquisition Transaction will be equal to the sum of the cash amount per share
payable pursuant thereto and the fair market value per share (as agreed to in
good faith by AWS and USA Waste or, absent such agreement, as determined by
Houlihan Lokey) of any non-cash consideration payable pursuant thereto.

Expenses

     The Merger Agreement provides that all costs and expenses incurred in
connection with the Merger Agreement and the transactions contemplated thereby
will be paid by the party incurring such expenses.

Indemnification

     The Merger Agreement provides that the indemnification provisions of the
Articles of Incorporation of AWS as in effect on the Closing Date will not be
amended, repealed or otherwise modified for a period of six years from the
Closing Date in any manner that would adversely affect the rights thereunder of
individuals who on the Closing Date were directors, officers, employees or
agents of AWS, unless such modification is required by law.

     The Merger Agreement also provides that, after the Closing Date, each of
USA Waste and AWS will, to the fullest extent permitted under applicable law,
indemnify and hold harmless each present and former director, officer, employee
and agent of AWS or any of its subsidiaries (each, together with such person's
heirs, executors or administrators, an "Indemnified Party" and collectively, the
"Indemnified Parties") against any costs or expenses (including attorneys'
fees), judgments, fines, losses, claims, damages, liabilities and amounts paid
in settlement in connection with any actual or threatened claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of, relating to, or in connection with, any action or
omission occurring or alleged to occur prior to the Closing Date (including,
without limitation, acts or omissions in connection with any such person serving
as an officer, director or other fiduciary in any entity if such service was at
the request or for the benefit of AWS) or arising out of or pertaining to the
transactions contemplated by the Merger Agreement or the Distribution Agreement.
In the event of any such actual or threatened claim, action, suit, proceeding or
investigation (whether arising before or after the Closing Date), (a) AWS and
USA Waste will pay the reasonable fees and expenses of counsel selected by the
Indemnified Parties,

                                       46
<PAGE>
 
which counsel will be reasonably satisfactory to USA Waste and AWS, promptly
after statements therefor are received and will pay all other reasonable
expenses in advance of the final disposition of such claim, action, suit,
proceeding or investigation, (b) USA Waste and AWS will cooperate and use all
reasonable efforts to assist in the vigorous defense of any such matter, and (c)
to the extent any determination is required to be made with respect to whether
an Indemnified Party's conduct complies with the standards set forth under the
OGCL and USA Waste's or AWS's charter or bylaws, such determination will be made
by independent legal counsel acceptable to USA Waste and AWS and the applicable
Indemnified Party; provided, however, that neither USA Waste nor AWS will be
liable for any settlement effected without its written consent (which consent
will not be unreasonably withheld); and, provided, further, that if USA Waste or
AWS advances or pays any amount to any person under the provisions described in
this paragraph and if it thereafter is finally determined by a court of
competent jurisdiction that such person was not entitled to be indemnified under
the Merger Agreement for all or any portion of such amount, to the extent
required by law, such person will repay such amount or such portion thereof, as
the case may be, to USA Waste or AWS, as the case may be. The Indemnified
Parties as a group may not retain more than one law firm to represent them with
respect to each matter unless there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two or more Indemnified Parties.

     USA Waste and AWS will not cancel or terminate any policies of directors'
and officers' liability insurance covering Indemnified Parties that does not
extend coverage for more than one year after the Closing Date.  Furthermore, USA
Waste will pay all reasonable expenses, including reasonable attorneys' fees,
that may be incurred by any Indemnified Party in enforcing the indemnity and
other obligations described above.  The rights of each Indemnified Party under
the Merger Agreement will be in addition to, and not in limitation of, any other
rights such Indemnified Party may have.  The indemnification provisions
described above will survive the consummation of the Merger.

Voting Agreement

     In connection with the Transactions, Messrs. Klingle and Wilson have
entered into voting agreements with USA Waste and AWS (each, a "Voting
Agreement").  Pursuant to his Voting Agreement, each of Messrs. Klingle and
Wilson has agreed to vote for approval of the Proposals and has given an
irrevocable proxy to USA Waste with respect thereto.  In addition, each of them
has agreed not to sell, transfer, assign, pledge, hypothecate, cause to be
redeemed or otherwise dispose of any of his shares of AWS Class B Common Stock
or grant any proxy with respect to any of those shares or deposit any of those
shares into a voting trust or enter into another voting agreement with respect
to any of those shares until his Voting Agreement is terminated.

              RELATIONSHIP AND ARRANGEMENTS BETWEEN AWS AND AVALON

     In connection with the Spin-off, Avalon and AWS will enter into several
agreements for the purpose of giving effect to the Spin-off and defining their
relationships thereafter.  Although these agreements may have been finalized
while Avalon was wholly-owned by AWS, they are the results of arms-length
negotiations with USA Waste.  Following the Transactions, additional

                                       47
<PAGE>
 
or modified agreements, arrangements and transactions may be entered into among
Avalon, AWS, USA Waste and their respective affiliates and subsidiaries. Any
such agreements, arrangements and transactions will be determined through arms-
length negotiations between the parties in the ordinary course of business.

     The following is a summary of certain agreements and arrangements between
Avalon and AWS that will become effective after the Spin-off.  Certain of these
agreements have been filed as exhibits to Avalon's Registration Statement on
Form 10 (the "Registration Statement") registering the Avalon Class A Common
Stock under the Exchange Act.  The following descriptions do not purport to be
complete and are qualified in their entirety by reference to such exhibits.  See
"Available Information."

Tax Allocation Agreement

     AWS and Avalon will enter into a tax allocation agreement, a form of which
is attached as an exhibit to the Registration Statement (the "Tax Allocation
Agreement"), that provides for the allocation between AWS and Avalon of all
responsibilities, liabilities and benefits relating to or affecting taxes paid
or payable by either AWS or Avalon, as the case may be, for all taxable periods,
whether beginning before, on or after the Transactions Record Date and to
provide for certain other matters.  The Tax Allocation Agreement also provides
mechanisms for cooperating in preparing and filing returns and with respect to
payment of tax liabilities, tax refunds and carryback items and further provides
for certain indemnification rights and obligations between AWS and Avalon for
tax and related liabilities which may result due to the Spin-off and/or the
Merger.

     The Tax Allocation Agreement will not be binding on the Internal Revenue
Service or any other taxing authority.

Non-Competition Arrangement

     The Distribution Agreement provides that, for a period of three years
commencing on the Transactions Record Date, Avalon will not directly or
indirectly (i) carry on or be engaged in (other than for the account of AWS or
USA Waste) the collection of refuse or garbage or the disposal of nonhazardous
solid waste from any source located within a 100-mile radius of the American
landfill, the Mahoning landfill or the East Liverpool landfill of AWS or (ii)
share in the earnings of, or beneficially own or hold any interest in, any
person who or which owns or operates a landfill within a 100-mile radius of the
American landfill, the Mahoning landfill or the East Liverpool landfill of AWS.

     The above-described covenant does not prevent Avalon from (i) owning,
solely as an investment, no more than 5% of the securities of any person if
Avalon is not an affiliate of such person, (ii) engaging in the provision of
technical and engineering services, transportation, and equipment sales and
leasing, (iii) engaging in the management or operation of captive landfills, and
(iv) engaging in the disposal and brokerage of disposal of nonhazardous solid
waste that is generated (or is deposited at a transfer station owned or operated
by Avalon) within any of the

                                       48
<PAGE>
 
above described 100-mile radii so long as Avalon provides AWS or USA Waste the
right to make a proposal for disposal of any such waste. Avalon will be
obligated to accept such proposal if the disposal rate quoted by AWS plus the
bona fide costs to be incurred by Avalon in transporting such waste to the
applicable AWS landfill is less than or equal to the total of the lowest bona
fide disposal rate quoted by a third party for such waste plus the bona fide
costs to be incurred by Avalon in transporting such waste to the applicable
landfill of such third party.

     In connection with the Transactions, Ronald E. Klingle and Darrell D.
Wilson have agreed to enter into individual non-competition agreements
containing restrictions and obligations substantially the same as those
described in the two immediately preceding paragraphs.

Transitional Services Agreement

     In connection with the Transactions, AWS and Avalon have agreed to enter
into a mutually acceptable agreement under which Avalon will provide to AWS, if
requested, certain services and facilities, including administrative and
bookkeeping services, to allow for a smooth transition subsequent to the closing
of the Transactions.

Other Arrangements

     Pursuant to the Distribution Agreement, AWS and Avalon have agreed that
after the Transactions Record Date agreements with third-party customers that by
reason of the Spin-off would require services to be provided by both AWS and
Avalon will continue to be performed by both AWS and Avalon, as appropriate, and
in a manner consistent with established "inter-company" pricing.  Although such
"inter-company pricing" was determined when all services were being performed by
AWS and therefore is not the result of arms-length negotiations between
independent parties, Avalon believes that the pricing terms are comparable to
what could be achieved through arms-length negotiations.

     As a result of the Spin-off, prior to the assignment or transfer of certain
contracts, licenses or permits to Avalon, the prior consent of third parties and
various filings or recordings with governmental entities may be required.  If
consent to the assignment or transfer of any contract, license or permit to be
contributed to Avalon is not obtained, AWS and Avalon will develop alternative
approaches so that, to the maximum extent possible, Avalon will receive the
benefits of such contract, license or permit and will discharge the duties and
bear the costs and risks thereunder.  Avalon will bear the risk that such
alternative arrangements will not provide Avalon with the full benefits of such
contract, license or permit.  AWS and Avalon, however, believe that they will be
able to obtain all necessary consents that are material to the Avalon Business.

                              ACCOUNTING TREATMENT

     In the separate financial statements of Avalon, the assets and liabilities
contributed to Avalon will be recorded at AWS's historical basis.  The
acquisition of AWS by USA Waste by means of the Merger will be accounted for as
a purchase.

                               DISSENTERS' RIGHTS

     Holders of outstanding shares of AWS Common Stock have the right to dissent
from the Merger.  The following is a summary of the principal steps which a
stockholder must take to perfect dissenters' rights under Section 1701.85.  This
summary is qualified in its entirety by the text of Section 1701.85, a copy of
which is attached to this Proxy Statement as Appendix D.  A failure to take any
one of the required steps may result in the termination of the rights of a
stockholder under Section 1701.85.  An exercise of dissenters' rights under
Section 1701.85 may result in a judicial determination that the "fair cash
value" of a dissenting stockholder's shares is

                                       50
<PAGE>
 

higher or lower than the $4.00 cash consideration to be paid for each share of
AWS Common Stock in the Merger.

     Any stockholder of record on the Special Meeting Record Date whose shares
are not voted for approval and adoption of the Merger Agreement may be entitled,
if the Merger is consummated, to be paid the "fair cash value" of such shares to
the extent held of record on the day prior to the date of the Special Meeting.
To be entitled to such payment, such stockholder must serve a written demand
therefor upon AWS at One American Way, Warren, Ohio 44484 on or before the tenth
day after the stockholder vote adopting the Merger Agreement and must otherwise
comply with Section 1701.85.  AWS will not inform stockholders of the expiration
of the ten-day period and therefore dissenting stockholders are advised to
retain a copy of this Proxy Statement.  A vote for approval and adoption of the
Merger Agreement constitutes a waiver of dissenters' rights.  Submission of a
properly executed proxy without a designation of "against" or "abstain" will
constitute a vote for the Proposal.  A failure to vote does not constitute a
waiver of dissenters' rights.  The required written demand must specify the
stockholder's name and address, the number of shares held of record on the day
prior to the date of the Special Meeting and the amount claimed as the "fair
cash value" of the shares.  Voting against approval and adoption of the Merger
Agreement will not of itself constitute a written demand required by Section
1701.85.

     If AWS requests, a dissenting stockholder must submit his or her share
certificates to AWS within 15 days after the making of such request for
endorsement thereon by AWS of a legend that demand for appraisal has been made.
Such certificates will be returned promptly to the dissenting stockholder by
AWS.  AWS intends to make such a request to dissenting stockholders.

     If AWS and any dissenting stockholder cannot agree on the "fair cash value"
of his or her shares of AWS Common Stock, either one may, within three months
after service of the demand by that stockholder, file a complaint in the Court
of Common Pleas of Trumbull County, Ohio for a determination of the "fair cash
value" of such stockholder's AWS Common Stock. The Court, if it determines that
the dissenting stockholder is entitled to be paid the "fair cash value" of his
or her AWS Common Stock, may appoint one or more appraisers to determine its
value. If the Court approves the appraisers' report, judgment will be entered
therefor, and the costs of the proceeding, including reasonable compensation to
the appraisers, will be assessed or apportioned as the Court considers
equitable. AWS does not intend to file such a complaint. Therefore, a dissenting
stockholder must timely file such a complaint to protect his or her rights to a
judicial determination under Section 1701.85.

     "Fair cash value" is the amount which a willing seller, under no compulsion
to sell, would be willing to accept and which a willing buyer, under no
compulsion to purchase, would be willing to pay, but in no event in excess of
the amount specified in the applicable stockholder's demand.  "Fair cash value"
would be determined as of the day prior to that on which the stockholder vote is
taken at the Special Meeting and would exclude any appreciation or depreciation
in market value of AWS Common Stock resulting from the proposal of the Merger.

                                       51
<PAGE>
 


     The right of any dissenting stockholder to be paid the "fair cash value" of
his or her AWS Common stock will terminate if:  (i) for any reason the Merger,
although adopted by stockholder vote, does not become effective; (ii) the
dissenting stockholder fails to serve an appropriate timely written demand upon
AWS; (iii) the dissenting stockholder does not, upon request of AWS, timely
surrender his or her certificates for endorsement thereon of a legend to the
effect that demand for the "fair cash value" of such AWS Common Stock has been
made; (iv) the demand is withdrawn by the dissenting stockholder, with the
consent of the AWS Board; (v) AWS and the dissenting stockholder have not come
to an agreement as to the "fair cash value" of his or her AWS Common Stock and
neither files a complaint in the Court as described above; or (vi) the
dissenting stockholder has otherwise not complied with the requirements of
Section 1701.85.

     From the time a dissenting stockholder's demand is made until the
termination of the right arising from that demand, all rights accruing to such
stockholder's AWS Common Stock, including dividend and voting rights, will be
suspended.  If a dissenting stockholder's right to receive "fair cash value" is
terminated other than by the purchase of such dissenting stockholder's AWS
Common Stock by AWS, all such stockholder's rights with respect to his or her
AWS Common Stock will be restored to the stockholder.  If the Merger has then
been consummated, such rights will consist solely of the right to receive $4.00
per share in cash.

     If holders of more than ten percent of the outstanding shares of AWS Common
Stock properly demand dissenters' rights, USA Waste has the right to decline to
consummate the Merger.  See "The Transactions--The Merger and the Merger
Agreement--Conditions to the Merger."

                       BUSINESS AND PROPERTIES OF AVALON

Business

General
    
     Avalon was incorporated in Ohio on April 30, 1998 solely for the purpose of
effecting the Spin-off.  Avalon is a newly established holding company which
will own subsidiaries of AWS that historically performed the transportation
operations, technical environmental services operations, waste disposal
brokerage and management operations and golf course and related operations of
AWS.
     
     In January 1990, AWS acquired Envirco Transportation, Inc., a hazardous and
nonhazardous waste transporter;  Envirco Transportation Management, Inc., a
waste transportation brokerage and management business; and DartAmericA, Inc., a
hazardous and nonhazardous waste transporter and common carrier.

     In October 1990, AWS acquired its environmental consulting, laboratory and
remediation companies:  Earth Sciences Consultants, Inc., Antech Ltd., and AWS
Remediation, Inc.  These 

                                       52
<PAGE>
 
technical environmental services firms are referred to collectively as the
"Earth Sciences Companies."

     During 1995, American Waste Management Services, Inc., a wholly owned
subsidiary of AWS, commenced waste disposal brokerage and management operations.
These operations had previously been held by AWMS, Inc., which was acquired by
AWS in January 1990 and no longer transacts business.

     During the third quarter of 1997, through a newly organized subsidiary,
American Landfill Management, Inc., AWS started its captive landfill management
operations.

Business Segments Information

     Avalon's primary business segments are transportation services, technical
environmental services and waste disposal brokerage and management services that
are provided to industrial, commercial, municipal and governmental customers
primarily in selected eastern and midwestern U. S. markets. Avalon's
transportation services segment provides transportation of hazardous and
nonhazardous waste, transportation of general and bulk commodities and the
brokerage and management of transportation services.  For the years 1997, 1996
and 1995, the net operating revenues of the transportation services segment
represented approximately 57%, 49% and 49%, respectively, of Avalon's total
segments' net operating revenues.  Avalon's technical environmental services
segment provides environmental consulting, engineering, site assessments,
analytical laboratory, remediation and captive landfill management services.
For the years 1997, 1996 and 1995, the net operating revenues of the technical
environmental services segment represented approximately 27%, 33% and 34%,
respectively, of Avalon's total segments' net operating revenues.  Avalon's
waste disposal brokerage and management services segment provides hazardous and
nonhazardous waste disposal brokerage and management services. For the years
1997, 1996 and 1995, the net operating revenues of the waste disposal brokerage
and management services segment represented approximately 11%, 12% and 13%,
respectively, of Avalon's total segments' net operating revenues. See the
Historical Combined Financial Statements of the Avalon Business of American
Waste Services, Inc. and the notes thereto contained elsewhere herein for
financial information relating to business segments. Avalon also operates a golf
course and related operations.

Transportation Services

General

     Avalon's transportation subsidiaries transport waste and other materials on
behalf of customers within the United States and portions of Canada and provide
transportation brokerage and management services, as well as intermodal
transportation services.  The transportation operations have the equipment and
the expertise to transport virtually all types of waste and most commodity
products.

                                       53
<PAGE>

DartAmericA, Inc.

     DartAmericA, Inc. and its subsidiaries (collectively, "Dart"),
headquartered in Canfield, Ohio, is engaged in the transportation of waste and
is a common carrier of both general and bulk commodities.  Dart, which commenced
operations in 1965, also engages in the brokerage of transportation.

     Dart is a fully licensed hazardous and nonhazardous waste carrier.
Approximately 60%, 59% and 62% of the revenue generated by Dart in 1997, 1996
and 1995, respectively, related to the transportation of waste.  Hazardous waste
represented 67%, 66% and 66% of Dart's waste transportation revenues in 1997,
1996 and 1995, respectively.

     Dart, which is licensed as a common carrier in 49 states and several
provinces of Canada, derived 40%, 41% and 38% of its revenues in 1997, 1996 and
1995, respectively, from the transportation of bulk commodities, such as coal,
salt, sand, ash, steel products and heavy machinery.  A common carrier engaged
in the transportation of goods owned by others is subject to federal and state
regulations which establish operating and safety standards.  Carriers are liable
for loss of or damage to goods entrusted to their care.  Public liability and
property damage insurance is compulsory.

     A majority of the truck power units, and a substantial number of the
trailers, used by Dart are owned and operated by independent truckers who
receive a negotiated percentage of the gross revenue from carriage.  Most of the
approximately 80 to 100 independent truckers who provide services for Dart have
been doing so for a number of years.  These independent truckers pay for fuel
and all other expenses with the exception of automotive liability insurance,
hazardous waste permits, special equipment required to carry hazardous waste and
other safety equipment, all of which are provided by Dart.  Equipment used by
the independent truckers is inspected at least annually and is subject to random
inspections by Dart.  See "Business and Properties of Avalon--Properties."

     Waste is transported by roll-off trailers, specialized tanker, van, dump or
flatbed trailers to treatment and disposal facilities.  Dart leases roll-off
containers to customers which fill the containers with waste as it is generated.
Using specially designed trailers, Dart periodically picks up and replaces the
containers, which it transports to approved facilities for disposal.  See
"Business and Properties of Avalon--Properties."

Envirco Transportation Management, Inc. ("ETMI")

     ETMI, established in 1988, is a waste transportation brokerage and
management company utilizing a network of licensed and approved carriers to
supplement the transportation capabilities of Dart. ETMI maintains lists of
approved transporters, which it periodically reviews and updates, and ETMI will
only engage transporters that it believes are reliable and efficient in
providing the services required in accordance with ETMI's standards.  ETMI also
performs project and intermodal management services for customers.

Technical Environmental Services

     The Earth Sciences Companies, headquartered in Export, Pennsylvania,
provide a wide range of technical environmental services, including
environmental impact studies, landfill design, permitting, site assessments,
waste management and minimization consulting, laboratory services, site
remediation, and environmentally related construction activities, including
removal of underground storage tanks, remediating Superfund sites, conducting
landfill closures and decommissioning.  These companies also provide hazardous
and nonhazardous waste management, groundwater remediation and underground
storage tank management.  The Earth Sciences Companies are often engaged to
perform a remedial investigation/feasibility study ("RI/FS"), which first
entails performing a site assessment involving the gathering of samples from a
contaminated site, followed by laboratory analysis to establish or verify the
nature and extent of the contaminants.  Alternative solutions to remedy the
particular problem are then developed, evaluated and presented to the client.
The Earth Sciences Companies are equipped to implement the mitigation and
decontamination program then selected by the client and approved by the
appropriate regulatory agency. When implementing such a program, the Earth
Sciences Companies may employ the transportation, management and/or brokerage
services of its affiliated companies.  The Earth Sciences Companies also possess
the expertise to perform the evaluation and analysis necessary to advise clients
regarding compliance with federal and state environmental regulations, and have
assisted clients in developing waste management and compliance policies,
including the development of plans for waste minimization and disposal.  The
Earth Sciences Companies also provide services related to the evaluation of the
environmental condition of real estate for law firms, banks or potential
purchasers, as well as expert environmental testimony in legal proceedings.

     The Earth Sciences Companies provide comprehensive organic, inorganic and
radiochemical laboratory services, including water and wastewater analyses,
waste characterization, sludge, soil and rock analyses and related bench studies
for wastewater treatment and process design.

     In 1997, 1996 and 1995, the Earth Sciences Companies derived approximately
95%, 96% and 95%, respectively, of their revenues from environmental
assessments, RI/FS's, industrial consulting, site remediation and laboratory
analyses services, and 5%, 4% and 5%, respectively, from consulting work in the
solid waste disposal area.

     American Landfill Management, Inc. ("ALMI") is a landfill management
company that provides technical and operational services to customers owning
captive disposal facilities.  A captive landfill facility is one that only
disposes of waste generated by the owner of such facility.  ALMI provides turn-
key services, including daily operations, facilities management and management
reporting for its customers.  Currently, ALMI manages one such captive landfill
facility located in Ohio.

Waste Disposal Brokerage and Management Operations

Disposal Brokerage and Management

     American Waste Management Services, Inc. ("AWMS") assists customers with
managing and disposing of wastes at approved treatment and disposal sites based
upon a customer's needs.

Waste Monitoring

     Because waste generators remain liable for their waste both before and
after disposal, they require assurance that their waste will be safely and
properly transported, treated and disposed of.  To give customers this
confidence, as well as to limit its own potential liability, AWMS has instituted
procedures designed to minimize the risks of improper handling or disposal of
waste.

     Prior to AWMS providing waste brokerage or management services, a potential
customer must complete a detailed questionnaire setting forth the amount,
chemical composition and any special characteristics for each separate waste to
be handled.  Representative samples of the waste are analyzed by a state or
federally certified laboratory.  In addition, an AWMS representative generally
inspects the process generating the waste, the location where the waste may be
temporarily stored or the site of the remediation project producing the waste,
and interviews representatives of the generator familiar with the waste.  This
inspection, along with the laboratory results, allows AWMS to determine whether
the waste is within acceptable parameters for disposal and, if so, what special
handling and treatment procedures must be instituted.  If the waste is
continuously generated, new representative samples are tested on a periodic
basis.

     These procedures are important to both AWMS and its customers since the key
to proper handling of waste is accurate identification.  Hazardous waste which
is not identified as such and thus improperly disposed of can result in
substantial liability to the waste generator, the disposal facility, AWMS and
potentially to all other waste generators that have used the disposal site.
Conversely, waste that could safely and legally be disposed of in a solid waste
landfill but is instead sent to a hazardous waste facility for treatment and
disposal will result in substantial and unnecessary expense to the generator.
 
Avalon Lakes

     In June 1990, AWS purchased approximately 5.6 acres of real estate located
in Howland Township, Ohio on which it constructed a 26,000 square foot office
building to serve as its corporate headquarters.  In connection with the
acquisition of such property, Avalon Lakes Golf, Inc. ("ALGI") acquired the real
and personal property associated with the Avalon Lakes Golf Course, an 18-hole
public golf course adjacent to the office property.  See "Business and
Properties of Avalon--Properties."

                                       56
<PAGE>

Governmental Regulations

     In order to transport hazardous waste and, in certain cases, nonhazardous
solid waste, Avalon's transportation operations must possess and maintain one or
more state operating permits.  These operating permits must be renewed annually
and are subject to modification and revocation by the issuing agency.  In
addition, Avalon's waste transportation operations are subject to evolving and
expanding operational, monitoring and safety requirements.

     In the ordinary course of their operations, Avalon's subsidiaries may from
time to time receive citations, notices or comments from regulatory authorities
that such operations are not in compliance with applicable environmental
regulations.  These agencies may seek to impose fines or to revoke or deny
renewal of operating permits or licenses or to require the remediation of
environmental problems resulting from Avalon's transportation or waste brokerage
operations.  Upon receipt of such citations, notices or comments, the
appropriate subsidiary works with the authorities in an attempt to resolve the
issues raised.  Failure to correct the problems to the satisfaction of the
authorities could lead to fines and/or a curtailment or cessation of operations.

     The federal government and numerous state and local governmental bodies are
increasingly considering, proposing or enacting legislation or regulations to
either restrict or impede the disposal and/or transportation of waste.  A
significant portion of Avalon's disposal brokerage and transportation revenues
is expected to be derived from the disposal or transportation of out-of-state
waste.  Any law or regulation restricting or impeding the transportation of
waste or the acceptance of out-of-state waste for disposal could have a
significant negative effect on Avalon.  Avalon's transportation operations may
also be affected by the trend toward laws requiring the development of waste
reduction and recycling or other programs.

Sales and Marketing

     It is anticipated that Avalon's sales and marketing approach will be
decentralized, with each operation being responsible for its own sales and
marketing efforts.  Each operation will employ its own sales force which will
concentrate on expanding its business.

Competition

     The markets for the transportation of hazardous and nonhazardous waste and
for the transportation of general and bulk commodities are each highly
competitive.  There are numerous participants, and no one transporter has a
dominant market share.  Avalon competes primarily with other short and long-haul
carriers for both truckload and less than truckload shipments.  Competition for
the transportation of waste is based on the ability of the carrier to transport
the waste at a competitive price and in accordance with applicable regulations
and the latest advances in technology.  Competition for the transportation of
commodities is based primarily on price and service.


                                       57
<PAGE>
 

     Avalon's technical environmental services operations compete with numerous
large and small companies, each of which is able to provide one or more of the
environmental services offered by Avalon and some of which have greater
financial resources.  Avalon attempts to develop relationships with clients who
have an ongoing need for its integrated technical environmental services.  The
availability of skilled technical personnel, the quality of performance and
service, and fees are the key competitive factors in developing such
relationships.

     The hazardous and nonhazardous waste disposal brokerage and management
business is highly competitive and fragmented.  Avalon's waste disposal
brokerage and management business competes with other brokerage companies as
well as with companies which own treatment and disposal facilities.

Insurance

     Avalon carries $21,000,000 of comprehensive general liability insurance
coverage for Avalon and its subsidiaries (other than with respect to ALGI, which
has separate insurance).  This policy includes coverage for automobile liability
(including a pollution liability endorsement which covers certain liabilities
from spills), comprehensive property damage and other customary coverage.  Dart
self-insures collision risks.  The Earth Sciences Companies also maintain
professional and pollution legal liability coverage.  No assurance can be given
that such insurance will be available in the future or, if available, that the
premiums for such insurance will be reasonable.

     If Avalon were to incur a substantial liability for damages not covered by
insurance or in excess of its policy limits or at a time when Avalon no longer
is able to obtain appropriate liability insurance, its condition could be
materially adversely affected.

     Avalon has entered into contracts with governmental authorities for a
variety of environmental services.  Typically, such contracts require surety
bonds or other financial instruments to assure performance under the terms
thereof.  Avalon has obtained in the past, and expects to be able to obtain in
the future, such bonds or other financial instruments.

Employees

     As of December 31, 1997, Avalon had no employees.  As of December 31, 1997,
the Avalon Business had 363 employees, 148 of whom were employed in
transportation operations, 160 of whom were employed in technical environmental
services and 55 of whom were employed by the golf course or related operations.
It is anticipated that certain employees of AWS will be employed by Avalon or
its subsidiaries upon consummation of the Transactions, primarily in the areas
of administrative support and sales.  The extent of such employment has not yet
been determined.  Each of the subsidiaries of AWS constituting part of the
Avalon Business believes that it has a good relationship with its employees.


                                       58
<PAGE>
 
Other Business Factors

     None of Avalon's business segments is materially dependent on patents,
trademarks, licenses, franchises or concessions, other than permits, licenses
and approvals issued by regulatory agencies, nor does Avalon sponsor significant
research and development activities.

     Historically, a significant portion of the Avalon Business' revenues was a
result of AWS's disposal business.  The transportation services segment of the
Avalon Business obtained approximately 14%, 14% and 13% of its net operating
revenues from AWS's disposal subsidiaries in 1997, 1996 and 1995, respectively.
Upon consummation of the Transactions, those disposal facilities and
transportation operations will no longer be affiliated.  Therefore, there can be
no assurance that such transportation services and resulting revenues will
continue in the future.  The loss of such revenues could, if not replaced, have
an adverse impact upon Avalon.

Properties

     Dart provides transportation services from locations in Canfield, Ohio
(Dart's headquarters, 19,500 square feet); Oxford, Massachusetts (where Dart
leases a 5,760 square foot terminal); Toledo, Ohio (where Dart rents a 720
square foot terminal); Kenova, West Virginia (where Dart leases a 1,500 square
foot terminal); and Chicago, Illinois (where Dart rents a 500 square foot
terminal).  At December 31, 1997, the transportation operations owned a fleet of
39 power units (in addition to 42 power units which are leased), 229 trailers
(in addition to 25 trailers which are leased and 115 which are rented), and 600
roll-off and other containers.  In addition, 120 to 140 power units and 155 to
175 trailers owned by independent owner/operators are available for use in
Dart's operations.  Certain transportation equipment acquired during 1993 is
subject to liens securing the repayment of indebtedness incurred to purchase
such equipment.

     The Earth Sciences Companies own their main offices and laboratory
facilities located in a 48,000 square foot building in Export, Pennsylvania.
The Earth Sciences Companies lease office space of approximately 4,000 square
feet in Akron, Ohio; 2,500 square feet in Blue Bell, Pennsylvania, near
Philadelphia; and 2,500 square feet near Denver, Colorado.  In addition, 13,000
square feet is leased for field equipment and vehicle storage and dispatch in
Murrysville, Pennsylvania. The Earth Sciences Companies also own numerous pieces
of laboratory, field, computer and other equipment.

     The captive landfill management operations use approximately six pieces of
equipment (such as a bulldozer, excavator and backhoe) all of which are owned by
ALMI.

     Upon consummation of the Transactions, Avalon will own a 26,000 square foot
headquarters building located on approximately 5.6 acres of property in Howland
Township, Ohio.  Adjacent to such property is an 18-hole public golf course
owned and operated by ALGI, including a maintenance and storage building of
approximately 12,000 square feet, a pro shop and restaurant building of
approximately 10,400 square feet, and a banquet facility of approximately 7,000
square feet.  The golf course property, together with the pro shop, restaurant


                                       59
<PAGE>
 
facility and banquet facility, serves as collateral securing repayment of
indebtedness incurred to construct such facilities.

     Generally, Avalon's fixed assets are in good condition and are satisfactory
for the purposes for which they are intended.

Legal Proceedings

     On or about October 3, 1991, one stockholder owning 100 shares of AWS Class
A Common Stock brought suit against AWS and others on behalf of himself and a
purported class of other stockholders in the United States District Court for
the Southern District of New York.  The suit, which was transferred to the
United States District Court for the Northern District of Ohio, alleges that
AWS, the signatories to its registration statement filed with the SEC during
October 1990, and AWS's underwriters violated federal securities laws in
connection with AWS's public offering of six million shares of AWS Class A
Common Stock in October 1990.  Among other things, the suit alleges
misrepresentations and failures to disclose allegedly material information
concerning the nature of AWS's market; the size of AWS's market; AWS's failure
to disclose that its landfills were located within a 50-mile radius of each
other in Ohio, thus making AWS especially vulnerable to local conditions and
competition; AWS's failure to set forth present and imminent competition; and
AWS's growth.  The plaintiff sought damages in an unspecified amount alleged to
have arisen in part from the decline in the price of AWS's stock following the
public offering and rescission.

     On September 26, 1997, the Court granted the defendants' Motion for Summary
Judgment and dismissed the plaintiff's case.  On October 25, 1997, pursuant to
the federal rules of appellate procedure, the plaintiff filed a notice of
appeal.  Such appeal is currently pending and AWS intends to vigorously defend
the Court's order.  Pursuant to the Distribution Agreement, Avalon has agreed to
assume and indemnify AWS for any costs and potential liability with respect to
this matter.

     In September 1995, certain subsidiaries of the Avalon Business were
informed that they had been identified as potentially responsible parties by the
Indiana Department of Environmental Management with respect to a Fulton County,
Indiana hazardous waste disposal facility which is subject to remedial action
under Indiana environmental laws. Such identification is based upon the
subsidiaries having been involved in the transportation of hazardous substances
to the facility. These transportation activities occurred prior to the
acquisition of such subsidiaries by AWS. During the third quarter of 1997, these
subsidiaries became parties to an Agreed Order for Remedial
Investigation/Feasibility Study and the Four County Landfill Site Participation
Agreement (the "Participation Agreement"). A large number of waste generators
and other waste transportation and disposal companies have also been identified
as responsible or potentially responsible parties with respect to this facility.
Because the relevant law provides for joint and several liability among the
responsible parties, any one of them, including these subsidiaries, could be
assessed the entire cost of the remediation, although this is unlikely.
Currently, no remedy has been selected, and the extent of any ultimate liability
of any of these subsidiaries with respect to this facility is unknown.

     When Avalon concludes that it is probable that a liability has been
incurred with respect to a site, provision will be made in Avalon's financial
statements reflecting its best estimate of the liability based on management's
judgment and experience, information available from regulatory agencies, and the
number, financial resources and relative degree of responsibility of other
potentially responsible parties who are jointly and severally liable for
remediation of that site as well as the typical allocation of costs among such
parties.  If a range of possible outcomes is estimated and no amount within the
range appears to be a better estimate than any other, then Avalon will provide
for the minimum amount within the range, in accordance with generally accepted
accounting principles.  Similarly, the Avalon Business accrued a liability of
approximately $941,000 in the fourth quarter of 1995 relating to this Indiana
facility.  Avalon's estimates are revised, as deemed necessary, as additional
information becomes known.  Avalon anticipates obtaining additional information
over the next several months by reason of, among other things, having entered
into the Participation Agreement.

     While the measurement of environmental liabilities is inherently difficult
and the possibility remains that technological, regulatory or enforcement
developments, the results of environmental studies or other factors could
materially alter Avalon's expectations at any time, Avalon does not anticipate
that the amount of any such revisions will have a material adverse effect on it.

     In addition to the foregoing, in the ordinary course of conducting their
businesses, subsidiaries of Avalon become involved in lawsuits, administrative
proceedings and governmental investigations, including those relating to
environmental matters.  Any of these proceedings may result in fines, penalties
or judgments being assessed which, from time to time, may have an impact on an
Avalon subsidiary's business and financial condition.  Avalon does not believe
that any pending proceedings, individually or in the aggregate, would have a
material adverse effect on it.

Liquidity and Capital Resources

     During 1997, the Avalon Business utilized existing cash to meet operating
needs, repay indebtedness, and fund capital expenditure programs.  Cash provided
by operations for 1997, 1996 and 1995 totaled $2.7 million, $0.4 million and
$6.1 million, respectively.

     Working capital decreased to $13.7 million at December 31, 1997 compared
with $15.3 million at December 31, 1996.  The decrease in working capital is
primarily attributable to a decrease in accounts receivable from AWS and its
subsidiaries (other than those constituting part of the Avalon Business) and
prepaid expenses and increased accounts payable. Accounts payable increased at
December 31, 1997 compared to December 31, 1996 primarily because of increased
subcontracting expenses as a result of increased business levels in the fourth
quarter of 1997 compared to the fourth quarter of the prior year.

     During 1997, the Avalon Business repaid $0.3 million of long-term
indebtedness.

     During 1997, capital spending for the Avalon Business totaled $2.9 million
which was principally related to the purchase of equipment for the
transportation and technical 

                                       64
<PAGE>
 
environmental services operations. The Avalon Business' capital spending in 1998
is expected to be approximately $2.0 million to $3.0 million. Capital
expenditures in 1998 will relate principally to acquiring transportation
equipment.

     Management believes that cash provided from operations, the availability of
working capital and the additional net assets being contributed by AWS, as well
as the Avalon Business' ability to incur indebtedness, will be for the
foreseeable future sufficient to meet operating requirements, fund debt
repayments, and fund capital expenditure programs.  The Avalon Business does not
currently have its own credit facilities.  To the extent required in the future,
any credit agreement will contain customary covenants and provisions.

Results of Operations

     The Avalon Business' primary business segment provides transportation
services which include transportation of hazardous and nonhazardous waste and
transportation of general and bulk commodities.  The technical environmental
services segment provides environmental engineering, site assessment, analytical
laboratory, remediation and captive landfill management services.  The waste
disposal brokerage and management services segment provides disposal brokerage
and management services for both hazardous and nonhazardous waste.  Other
businesses include the operation of a public golf course and related operations.


Performance in 1997 Compared with 1996

Overall Performance

     Net operating revenues were $60.7 million in 1997 compared to $61.4 million
in 1996.  While net operating revenues declined 1% in 1997 compared to 1996,
costs of operations increased approximately 4% to 90% of net operating revenues
in 1997 compared to 86% of net operating revenues in 1996.  The increase in
costs of operations was primarily attributable to the technical environmental
services segment as described below under Segment Performance.  Selling, general
and administrative expenses increased to $7.1 million in 1997 compared to $6.2
million in the prior year primarily as a result of an increase in the provision
for losses on accounts receivable, most of which was the result of a write-off
of an account receivable by the technical environmental services segment
associated with the settlement of a dispute regarding a remediation project in
Denver, Colorado.  Other income, which was fairly constant in 1997 and 1996, was
primarily the result of gains from the disposal of property and equipment.  The
Avalon Business incurred a net loss of $0.7 million in 1997 compared with net
income of $1.3 million in 1996.

Segment Performance

     Segment performance should be read in conjunction with Note 10 to the
Historical Combined Financial Statements of the Avalon Business of American
Waste Services, Inc.

     Net operating revenues of the transportation services segment increased
10.6% to $36.3 million in 1997 compared to $32.8 million in 1996.  The increase
in net operating revenues is primarily attributable to increased transportation
of hazardous and nonhazardous waste and


                                       65
<PAGE>
 
general and bulk commodities. The transportation services segment recorded
operating income of $2.1 million in 1997 compared to $1.8 million in 1996.
Operating income of the transportation services segment increased in 1997
compared to 1996 primarily as a result of increased transportation of hazardous
and industrial waste and, to a lesser extent, increased transportation of
general and bulk commodities.

     Net operating revenues of the technical environmental services segment
decreased 23.8% to $17.0 million in 1997 compared to $22.3 million in 1996.
This decrease in net operating revenues was primarily a result of a significant
decline in remediation and engineering services provided.  The technical
environmental services segment incurred a net operating loss of $2.6 million in
1997 compared to net operating income of $0.7 million in 1996.  The operating
loss of the technical environmental services segment was primarily attributable
to losses incurred during the first quarter of 1997 in connection with a
remediation project in Denver, Colorado and a pretax charge of $0.5 million
during the third quarter of 1997 relating to the settlement of a dispute
regarding the project, as well as operating inefficiencies and delays at other
remediation projects.  The operating loss was also attributable to decreased
levels of engineering, consulting and remediation services provided.

     Net operating revenues of the waste disposal brokerage and management
segment decreased 13% to $7.0 million in 1997 compared to $8.1 million in 1996.
This decrease in net operating revenues is primarily a result of a reduction in
the level of disposal brokerage and management business.  The waste disposal
brokerage and management services segment recorded operating income of $0.9
million in 1997 compared to $1.2 million in 1996.  The decrease in operating
income was primarily attributable to decreased levels of business and, to a
lesser extent, decreased profit margins.

Interest Expense

     Interest expense decreased to $118,000 in 1997 compared to $141,000 in 1996
primarily due to a decrease in the amount of principal outstanding under the
Avalon Business' long-term indebtedness.

General Corporate Expenses

     General corporate expenses were $1.7 million in both 1997 and 1996.  Such
expenses were attributable to corporate expenses of AWS which were allocated to
the Avalon Business.
 
Net Income

     The Avalon Business recorded a net loss of $0.7 million in 1997 compared
with net income of $1.3 million in 1996 primarily as a result of the foregoing.
The Avalon Business recorded an income tax benefit of $0.1 million in 1997
compared to a provision for income taxes of $0.9 million in 1996.  The Avalon
Business' overall effective income tax rate, including the effect of state
income tax provisions, was 17.2% in 1997 and 40.7% in 1996.  The 1997 overall
effective income tax rate was lower than the statutory income tax rate primarily
as a result of permanent differences relating to the amortization of certain
intangibles as well as the inability to recognize net operating loss benefits
for state income tax purposes.

Performance in 1996 Compared with 1995

Overall Performance

     Net operating revenues were $61.4 million in 1996 compared to $65.7 million
in 1995.  Net income totaled $1.3 million in 1996 compared with a net loss of
$14.7 million in 1995.  During 1995, in accordance with the Avalon Business'
asset impairment policy, the Avalon Business performed an analysis for
impairment of certain long-lived assets.  As a result, in 1995 the Avalon
Business incurred significant charges for the write-down of assets and the
write-down of costs in excess of fair market value of net assets of acquired
businesses and other intangibles.  Excluding the effects of the aforementioned
charges, costs of operations decreased to 86% of net operating revenues in 1996
compared to 93% of net operating revenues in 1995.  This decrease was primarily
attributable to decreased depreciation and amortization expense of the
transportation and technical environmental services segments and decreased
subcontractor costs of the technical environmental services segment.  Selling,
general and administrative expenses decreased to $6.2 million in 1996 from $7.0
million in 1995 primarily as a result of a decrease in the provision for losses
on accounts receivable of the transportation services segment.  Other income in
1996 consisted primarily of gains from the disposal of property and equipment.
In 1995, the Avalon Business incurred other expense, consisting primarily of the
writedown of certain property and equipment of the transportation services
segment.

Segment Performance

     Segment performance should be read in conjunction with Note 10 to the
Historical Combined Financial Statements of the Avalon Business of American
Waste Services, Inc.

     Net operating revenues of the transportation services segment decreased
8.7% to $32.8 million in 1996 compared to $35.9 million in 1995 primarily due to
the closing of two transportation terminals that resulted in decreased revenues
associated with the transportation of hazardous waste and, to a lesser extent,
the transportation of nonhazardous industrial waste and general and bulk
commodities.  The transportation services segment recorded operating income of
$1.8 million in 1996 compared to an operating loss of $3.9 million in 1995.  The
increase in operating income is primarily the result of decreased depreciation
and amortization expense in 1996 and the fact that 1995's operating results
included a charge of $3.2 million relating to impaired assets and the write-down
of costs in excess of fair market value of net assets of acquired businesses and
other intangibles.  Additionally, in 1995, the transportation services segment
recorded a liability of $0.9 million as a result of having been identified as a
potentially responsible party with respect to a hazardous waste disposal
facility, as more fully described in Note 8 to the Historical Combined Financial
Statements of the Avalon Business of American Waste Services, Inc. The increase
in operating income was also a result of a decrease in the provision for losses
on accounts receivable and the closing of transportation terminals in 1995 which
had high operating costs as a percentage of net operating revenues.

     Net operating revenues of the technical services segment decreased 10.4% to
$22.3 million in 1996 compared to $24.9 million in 1995 primarily as a result of
a decrease in the level of consulting, engineering and laboratory services
provided.  The technical environmental services segment recorded operating
income of $0.7 million in 1996 compared to a net operating 


                                       67
<PAGE>
 
loss of $11.2 million in 1995 primarily as a result of decreased depreciation
and amortization expense during 1996 and the fact that 1995's operating results
included a $10.1 million charge relating to the write-down of costs in excess of
fair market value of net assets of acquired businesses and other intangibles.

     Net operating revenues of the waste disposal brokerage and management
services segment decreased 15.6% to $8.1 million in 1996 compared to $9.6
million in 1995 primarily as a result of reduced levels of waste disposal
brokerage and management business.  The waste disposal brokerage and management
services segment recorded operating income of $1.2 million in 1996 compared to
$1.1 million in 1995 primarily as a result of increased profit margins.

Interest Expense

     Interest expense decreased to $141,000 in 1996 compared to $166,000 in 1995
primarily due to a decrease in the amount of principal outstanding under the
Avalon Business' long-term indebtedness.

General Corporate Expenses

     General corporate expenses were $1.7 million in both 1996 and 1995.  Such
expenses were attributable to corporate expenses of AWS which were allocated to
the Avalon Business.

Net Income (Loss)

     The Avalon Business recorded net income of $1.3 million in 1996 compared
with a net loss of $14.7 million in 1995 primarily as a result of the foregoing.
The Avalon Business recorded a provision for income taxes of $0.9 million in
1996 compared to a benefit for income taxes of $1.0 million in 1995.  The Avalon
Business' overall effective income tax rate, including the effective state
income tax provisions, was 40.7% in 1996 and 6.4% in 1995.  The 1995 overall
effective income tax rate was substantially lower than the statutory income tax
rate primarily because of the nondeductibility for tax purposes of the
amortization and write-down of costs in excess of fair market value of net
assets of acquired businesses.

Trends and Uncertainties

     In the ordinary course of conducting its business, the Avalon Business
becomes involved in lawsuits, administrative proceedings and governmental
investigations, including those relating to environmental matters.  Some of
these proceedings may result in fines, penalties or judgments being assessed
against the Avalon Business which, from time to time, may have an impact on its
business and financial condition.

     The federal government and numerous state and local governmental bodies are
increasingly considering, proposing or enacting legislation or regulations to
either restrict or impede the disposal and/or transportation of waste.  A
significant portion of the Avalon Business' disposal brokerage and
transportation revenues is expected to be derived from the disposal or
transportation of out-of-state waste.  Any law or regulation restricting or
impeding the transportation of waste or the acceptance of out-of-state waste for
disposal could have a significant negative effect on the Avalon Business.  The
Avalon Business' transportation 


                                       68
<PAGE>
 
operations may also be affected by the trend toward laws requiring the
development of waste reduction and recycling or other programs.

     Competitive pressures within the environmental industry continue to impact
the financial performance of the Avalon Business' transportation services,
technical environmental services and waste disposal brokerage and management
services.  A further decline in the rates which customers are willing to pay for
its services could adversely impact the future financial performance of the
Avalon Business.

     During the fourth quarter of 1996, the technical services business began
experiencing operating losses.  Such losses have continued during 1997 primarily
as a result of inefficiencies and delays occurring at certain remediation
projects.  These operating losses adversely affected the Avalon Business'
operating results and may continue to impact them in the future.

     Many of the services provided by the Avalon Business are terminable by
customers on short notice.  If customers react unfavorably to the Transactions,
such customers may decide to terminate such services which could adversely
impact the future financial performance of the Avalon Business.

     Historically, a significant portion of the Avalon Business's transportation
revenues was a result of AWS's disposal business.  Upon consummation of the
Transactions, those disposal facilities and Avalon's transportation operations
will no longer be affiliated.  Therefore, there can be no assurance that such
transportation services and resulting revenues will continue in the future.  The
loss of such revenues could, if not replaced, have an adverse impact upon the
Avalon Business' future financial performance.

     There is no assurance that, as a stand-alone company, the Avalon Business'
results of operations will continue at a level similar to its results of
operations while a part of AWS.  Subsequent to the Transactions, the Avalon
Business will be a less diversified company than is currently the case with
respect to AWS.  As a result, Avalon may be more susceptible to competitive and
market factors than the Avalon Business was as part of AWS.  The Avalon
Business' selling, general and administrative expenses and costs of operations
after the Spin-off are anticipated to be significantly higher than the
historical expenses and costs of the Avalon Business because certain selling,
general and administrative expenses and costs of operations of AWS that have
historically not been allocated to subsidiaries of AWS or have historically been
allocated to subsidiaries of AWS that are not part of the Avalon Business will
be selling, general and administrative expenses and costs of operations of
Avalon.

Market Risk

     The Avalon Business does not have significant exposure to changing interest
rates because of the low level of indebtedness of the Avalon Business.  The
Avalon Business does not undertake any specific actions to cover its exposure to
interest rate risk and the Avalon Business is not a party to any interest rate
risk management transactions.


                                       69
<PAGE>
 
     The Avalon Business does not purchase or hold any derivative financial
instruments for trading purposes.

     An 80 basis point move in interest rates (10% of the Avalon Business'
weighted average interest rate) affecting the Avalon Business' floating
financial instruments, including both debt obligations and investments, would
have an immaterial effect on the Avalon Business' pretax earnings for the next
fiscal year.  The 80 basis point move in interest rates would also have an
immaterial effect on the fair value of the Avalon Business' fixed rate financial
instruments.

Inflation Impact

     The Avalon Business has not entered into any long-term fixed price
contracts that could have a material adverse impact upon its financial
performance in periods of inflation.  In general, management believes that
rising costs resulting from price inflation could be passed on to customers;
however, the Avalon Business may need to absorb all or a portion of these cost
increases depending upon competitive conditions at the time.  As is the case
with any transportation company, an increase in fuel prices may subject the
transportation operations to increased operating expenses, which the Avalon
Business, in light of competitive market conditions, may not be able to pass on
to its customers.

                              MANAGEMENT OF AVALON

Avalon Board of Directors

     The business of Avalon will be managed under the direction of the Avalon
Board.  The current directors of Avalon are the five persons identified below

Date.  As with the current AWS Board, the Avalon Board is divided into two
classes.  Directors for each class will be elected at each annual meeting of
stockholders of Avalon.  Each individual listed below is currently a director of
AWS and will resign from the AWS Board effective as of the Closing Date.

     Mr. Ronald E. Klingle, who will become Chairman of the Avalon Board and
Avalon's Chief Executive Officer, and Mr. Darrell D. Wilson, who will become
Avalon's President and Chief Operating Officer, will resign from all their
positions at AWS effective as of the Closing Date.

     The following table sets forth information with respect to the persons who
are expected to serve as directors of Avalon following the Spin-off.  As
provided in the Avalon Articles, the Avalon Board will be divided into two
classes effective upon the Spin-off.  The table also sets forth the names of the
directors of each class and their periods of service as directors of AWS.

expected that two members of the Compensation Committee will be executive
officers of Avalon.

            AVALON BOARD COMMITTEE REPORT ON EXECUTIVE COMPENSATION

                  AVALON LONG-TERM INCENTIVE PLAN; 401(K) PLAN

Incentive Plan

     Prior to the Transactions Record Date, AWS, as the sole stockholder of
Avalon, will approve the adoption by Avalon of the Avalon Holdings Corporation
Long-Term Incentive Plan 


                                       75
<PAGE>
 
(the "Incentive Plan"). The purposes of the Incentive Plan will be to promote
and enhance the long-term growth of Avalon by aligning the interests of the
officers and directors of Avalon with those of Avalon's stockholders and to
assist in attracting persons to serve on the Avalon Board. The principal terms
of the Incentive Plan are summarized below; this summary is qualified in its
entirety by reference to the full text of the Incentive Plan which has been
filed with the SEC as an exhibit to the Registration Statement.

     Avalon will reserve 1,300,000 shares of Avalon Class A Common Stock for
issuance under the Incentive Plan to employees and non-employee directors.  The
Incentive Plan is effective only upon the effectiveness of the Spin-off.

Employees

     The Incentive Plan will permit the granting of both incentive stock options
("ISOs") and non-qualified stock options ("NQSOs") to employees.  Options will
be designated as ISOs or NQSOs, except that for tax purposes an option
designated as an ISO which does not qualify as such will be treated as an NQSO.
Both key employees and other salaried employees will be eligible for grants.
The Option Plan Committee of the Avalon Board will decide on the grants;
provided, that grants to a single person may not exceed 10% of the shares
allocated to the Incentive Plan for employees and ISO grants to a single
employee are subject to the dollar limitations imposed by the Internal Revenue
Code of 1986, as amended (the "Code").

     NQSOs may be granted with an exercise price that is not less than 85% of
the fair market value of the Avalon Class A Common Stock on the date of grant.
ISOs may be granted with an exercise price that is not less than 100% of the
fair market value of the Avalon Class A Common Stock on the date of grant,
except ISOs granted to an employee who owns 10% or more of the total combined
voting power of all classes of stock of Avalon must be at least 110% of the fair
market value on the date of grant.

     Options generally will have a 10-year term and must be exercised by the
optionee while employed by Avalon, except that (i) if an optionee's employment
terminates by reason of death or disability, the portion of his or her options
exercisable on the date of termination and all portions that would have become
exercisable had the optionee continued in employment until the third anniversary
of his or her death or disability will be exercisable for a six-month period
subsequent to termination (but not beyond 10 years from the date of grant) by
the optionee or the optionee's legal representatives, as the case may be, (ii)
if the termination is other than for death, disability or cause, the portion of
his or her options exercisable on the date of termination continues to be
exercisable for a three-month period subsequent to termination (but not beyond
10 years from the date of grant), and (iii) if employment is terminated for
cause, the unexercised portion of his or her options is forfeited and cancelled.
If an optionee dies while disabled during the aforesaid six-month period or dies
during the aforesaid three-month period, the portion of his or her options
exercisable on the date of death will continue to be exercisable for a six-month
period subsequent to the date of death (but not beyond 10 years from the date of
grant) by the optionee's legal representatives.


                                       76
<PAGE>
 
     No option will be exercisable prior to six months after its grant, unless
otherwise permitted by the Option Plan Committee, and thereafter options will be
exercisable in installments, if any, as provided by the Option Plan Committee.

Directors

     The Incentive Plan will also permit the granting of NQSOs to each non-
employee director of Avalon.  The exercise price of all options to be granted to
non-employee directors will be the fair market value on the date of grant.  No
option will be exercisable prior to six months after its grant, unless otherwise
permitted by the Avalon Board, and thereafter options will be exercisable in
installments, if any, as provided by the Avalon Board.

     Options to be granted to non-employee directors generally will have a 10-
year term.  If a non-employee director ceases to be a director by reason of
death, disability, resignation or removal, the portion of his or her options
which is exercisable on the date he or she leaves the Avalon Board and, if such
cessation is due to death or disability, all portions which would have become
exercisable had the non-employee director continued as a director until the
third anniversary of his or her death or disability will be exercisable for a
six-month period following such date (but not beyond 10 years from the date of
grant), and if the cessation is due to any reason other than death or removal
and the non-employee director dies during such six-month period, the option may
be exercised for a six-month period subsequent to the date of death (but not
beyond 10 years from the date of grant) by the director's legal representatives.

All Optionees

     The exercise price of any option under the Incentive Plan will be payable
upon exercise in cash, shares of Avalon Class A Common Stock having a value, at
the time of exercise, equal to such exercise price, or a combination thereof.
Options will not be transferable by optionees other than by will or by the laws
of descent and distribution.

     Options under the Incentive Plan may not be exercised except in compliance
with applicable securities laws and Avalon intends, after the effectiveness of
the Registration Statement, to register the shares reserved under the Incentive
Plan with the SEC.

     The number of shares reserved under the Incentive Plan will be subject to
adjustment under certain circumstances, such as stock splits, stock dividends
and recapitalizations.

     The Avalon Board may amend, suspend or terminate the Incentive Plan
provided that no action adversely affects any rights or obligations with respect
to any grants theretofore made or except as required under applicable law.

401(k) Profit Sharing Plan

     Avalon intends to establish a profit sharing plan which is a qualified tax
deferred employee benefit plan under Section 401(k) of the Code (the "401(k)
Plan").  Participation in the 401(k) Plan will be automatic upon attaining age
20 1/2 and having six months of service with 


                                       77
<PAGE>
 
Avalon (including for this purpose prior service with AWS). A participant may,
at his or her option, make salary deferral contributions of up to the maximum
amount permitted by the Code each year out of his or her annual compensation,
subject to special limitations imposed by the Code and the regulations
thereunder.

     It is anticipated that cash contributions by Avalon and salary deferral
contributions made on behalf of participants may be invested in one or more
investment funds as directed by the participant.  Participants may elect on a
periodic basis to reallocate their account balances in any of the plan funds to
any other plan fund or funds.  Contributions to the 401(k) Plan and the earnings
thereon may be withdrawn only following retirement, death or termination of
employment or in certain cases of financial hardship.

     Avalon has made no contributions to the 401(k) Plan to date for the benefit
of any executive officer.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires executive officers and directors
of the issuer of a registered class of equity securities and persons who own
more than 10 percent of such registered class of equity securities to file
reports of beneficial ownership and changes in beneficial ownership of such
equity securities with the SEC and the exchange on which such class of
securities is principally traded.  Avalon's prospective officers and directors
were not required to comply with Section 16(a) in 1997 as such because no equity
securities of Avalon were so registered.

        CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTIONS TO
                           AWS AND ITS STOCKHOLDERS

     The following is a summary of certain United States federal income tax
consequences of the Merger and the Spin-off.  This summary does not address all
aspects of federal income taxation that may be relevant to holders of AWS Common
Stock and is based on current provisions of the Code, existing, proposed and
temporary regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all of which are subject to change.  No assurance can
be given that future legislation, regulations, administrative interpretations
and court decisions will not significantly change these authorities, possibly
with retroactive effect.  This summary is based on advice received from
Kirkpatrick & Lockhart LLP, counsel to AWS.  Stockholders should note that this
discussion is not binding on the Internal Revenue Service ("IRS") or the courts
and that AWS has not sought, and does not intend to seek, a ruling from the IRS
as to any of the federal income tax consequences to either AWS or its
stockholders of the Transactions and no opinion of counsel has been or will be
rendered to AWS or its stockholders with respect to any of the federal income
tax consequences of the Merger or the Spin-off.

     This discussion applies only to holders of AWS Common Stock in whose hands
shares of AWS Common Stock are capital assets within the meaning of Section 1221
of the Code, and may not apply to AWS Common Stock received pursuant to the
exercise of employee stock 

                                       78
<PAGE>
 
options or otherwise as compensation, or to holders of AWS Common Stock subject
to special tax provisions (including, but not limited to, insurance companies,
banks, regulated investment companies, tax-exempt organizations and broker-
dealers, who may be subject to special rules under the Code). This discussion
does not address the federal income tax consequences to a holder of AWS Common
Stock who, for United States federal income tax purposes, is a non-resident
alien individual, a foreign corporation, a foreign partnership or a foreign
estate or trust, nor does it consider the effect of any foreign, state or local
tax laws.

The Spin-off

     Prior to the consummation of the Merger, AWS will undertake the Spin-off.
AWS will be required to recognize gain on the Spin-off to the extent of the
excess, if any, of the fair market value of the Avalon Common Stock over its
adjusted basis in the hands of AWS.  In order to determine such fair market
value for this purpose, a valuation of Avalon will be made by Houlihan Lokey
prior to the Spin-off.  See "Background and Reasons--Valuation of Avalon."

     As a result of the Spin-off, each holder of AWS Common Stock will be
considered to receive, to the extent of AWS's current and accumulated earnings
and profits, a taxable dividend includable in income in an amount equal to the
fair market value of the shares of Avalon Common Stock received in the Spin-off,
plus the cash received, if any, in lieu of a fractional share of Avalon Common
Stock.  The fair market value of the shares and cash, if any, distributed to the
AWS stockholders will be reported to each stockholder by way of an IRS Form
1099-DIV (the "1099-DIV") reflecting the valuation made by Houlihan Lokey.  The
portion of the Spin-off to each AWS stockholder that is taxable as a dividend
will be reported as "ordinary dividends" in Box #1 of the stockholder's 1099-
DIV.  AWS stockholders that are corporations generally will qualify for the 70%
intercorporate dividends-received deduction subject to satisfaction of the
minimum holding period (generally, the AWS Common Stock must be held for at
least 46 days within the 90 day period of time beginning 45 days before the AWS
Common Stock becomes ex-dividend) and other applicable requirements.  If the
dividend is an "extraordinary dividend," as defined by Section 1059(c) of the
Code, a corporate stockholder generally will be required to reduce its basis in
its AWS Common Stock by the amount of the dividends-received deduction it was
allowed.  An "extraordinary dividend" with respect to common stock is one in
which the amount of such dividend equals or exceeds 10% of the stockholder's
adjusted basis in its AWS Common Stock and the corporate stockholder had not
held the AWS Common Stock for more than two years as of February 6, 1998 (the
date the Spin-off was announced publicly).

     AWS's management anticipates that the value of the distributed Avalon
Common Stock, plus the amount of cash received, if any, in lieu of fractional
shares of Avalon Common Stock will exceed AWS's accumulated earnings and
profits. The portion of the Spin-off to each AWS stockholder that exceeds AWS's
accumulated earnings and profits will be reported as "nontaxable distributions"
in Box #3 of the 1099-DIV received by the stockholder. Any such excess will be
treated as a non-taxable return of capital to a recipient stockholder and each
recipient stockholder will reduce his or her adjusted basis in his or her shares
of AWS Common Stock in an amount equal to such excess. To the extent that the
non-taxable portion of the Spin-

                                       79
<PAGE>
 
off exceeds a stockholder's tax basis in his or her AWS Common Stock, the excess
will be treated as capital gain. A stockholder thus will recognize capital gain
to the extent the amount shown in Box #3 of the 1099-DIV exceeds the
stockholder's adjusted basis in his or her AWS Common Stock. Gain or loss must
be determined separately for each block of AWS Common Stock (i.e., AWS Common
Stock acquired at the same cost in a single transaction) and this gain will be
long-term or short-term depending on how long the stockholder has held the
shares of AWS Common Stock.

     Each stockholder's basis in the shares of Avalon Common Stock he or she
receives in the Spin-off will equal the fair market value of those shares on the
date of the Spin-off.  Each stockholder's holding period for those shares will
begin on the date after the date of the Spin-off.

The Merger

     For federal income tax purposes, the Merger will be treated as though USA
Waste purchased the AWS Common Stock directly from the AWS stockholders.  The
receipt of cash for AWS Common Stock pursuant to the Merger will be a taxable
transaction for federal income tax purposes and may also be a taxable
transaction under applicable state, local or foreign tax laws.  The income tax
consequences of such receipt pursuant to the Merger may vary depending upon,
among other things, the particular circumstances of the stockholder.  In
general, for federal income tax purposes, a stockholder will recognize capital
gain or loss equal to the difference between the stockholder's adjusted tax
basis in its shares of AWS Common Stock (following adjustments, if any, by
reason of the Spin-off described more fully above ) and the amount of cash
received in exchange for those shares of AWS Common Stock.  Gain or loss must be
determined separately for each block of AWS Common Stock (i.e., AWS Common Stock
acquired at the same cost in a single transaction) converted into cash pursuant
to the Merger.

     Under The Taxpayer Relief Act of 1997, the capital gains of an individual
holder who has held shares of AWS Common Stock for more than one year, but not
more than 18 months, will be subject to a maximum federal income tax rate of
28%.  If the shares of AWS Common Stock have been held by such holder for more
than 18 months, a maximum rate of 20% would apply to such capital gains.  If the
shares of AWS Common Stock have been held by such holder for 12 months or less,
the capital gains, if any, will be subject to federal income tax at rates
applicable to ordinary income.  Capital gains of a corporate stockholder are
subject to tax at normal corporate federal income tax rates.

     The Code limits the deductibility of capital losses.  For corporate
taxpayers, capital losses for a tax year may only be used to offset capital
gains for that tax year; and unused capital losses may, in general, be carried
back three years and carried forward five years. For individual taxpayers,
capital losses are deductible in each taxable year to the extent of any capital
gains and as an ordinary deduction up to an additional $3,000 ($1,500 in the
case of a married individual filing a separate return); and any unused capital
losses may be carried forward indefinitely.

                                       80
<PAGE>
 
Backup Withholding

     Payments to a stockholder in connection with the Merger and the Spin-off
may be subject to "backup withholding" at a rate of 31%, unless the stockholder
(i) is a corporation or comes within certain exempt categories and, when
required, demonstrates this fact, or (ii) provides a correct tax identification
number ("TIN") to the payor, certifies as to no loss of exemption from backup
withholding and otherwise complies with applicable requirements of the backup
withholding rules.  A stockholder who does not provide a correct TIN may be
subject to penalties imposed by the IRS.  Any amount withheld as backup
withholding does not constitute an additional tax and will be creditable against
the holder's federal income tax liability provided the required information is
provided to the IRS.  Each stockholder should consult with his or her own tax
advisor as to his or her qualification for exemption from backup withholding and
the procedure for obtaining such exemption.

     Because individual circumstances may differ, each stockholder should
consult such stockholder's own tax advisor to determine the applicability of the
rules discussed above and the particular tax effects to such stockholder of the
Merger and the Spin-Off, including the application and effect of state, local,
foreign and other income tax laws and changes in applicable tax laws.

                      DESCRIPTION OF AVALON CAPITAL STOCK

     The authorized capital stock of Avalon is 11,500,000 shares, consisting of
10,500,000 shares of Avalon Class A Common Stock and 1,000,000 shares of Avalon
Class B Common Stock.

    
     There are outstanding on the date of this Proxy Statement 1,000 shares of
Avalon Class A Common Stock.  Giving effect to the Spin-off, there will be
outstanding approximately 3,162,663 shares of Avalon Class A Common Stock and
640,482 shares of Avalon Class B Common Stock.
     
     The following description is a summary and is qualified in its entirety by
the provisions of  the Avalon Articles and Avalon Code, copies of which have
been filed as exhibits to the Registration Statement.

Voting Rights

     Each share of Avalon Class A Common Stock is entitled to one vote and each
share of Avalon Class B Common Stock is entitled to ten votes on all matters
submitted to a vote of the stockholders.  Except as described below or as
required by applicable law, the Avalon Class A Common Stock and the Avalon Class
B Common Stock vote together as a single class on all matters presented for a
vote of the stockholders.  Commencing with the first annual meeting of
stockholders after the Spin-off and for as along as the outstanding Avalon Class
B Common Stock has more than 50% of the total outstanding voting power of the
Avalon Common Stock, the holders of the Avalon Class A Common Stock, voting as a
separate class, will elect a number of directors equal to at least 25% of the
total Avalon Board, and the holders of the Avalon Class B Common Stock, voting
as a separate class, will elect the remaining directors.  Thereafter, the
holders of the Avalon Class A and Avalon Class B Common Stock will vote together
as a single class for the election of directors.  The holders of a majority of
all outstanding shares of Avalon Class A Common Stock or Avalon Class B Common
Stock, voting as a separate class, must also approve amendments to the Avalon
Articles that adversely affect the shares of their class.  Shares of Avalon
Class A Common Stock and Avalon Class B Common Stock do not have cumulative
voting rights.

Dividends

     The shares of Avalon Class A Common Stock and Avalon Class B Common Stock
are entitled to dividends at the same rate if, as and when declared by the
Avalon Board from any assets legally available therefor.  Any dividends so
declared and payable in cash, capital stock of Avalon (other than Avalon Class A
Common Stock or Avalon Class B Common Stock) or other property will be paid on a
corresponding and pro rata basis on the shares of Avalon Class A Common Stock
and Avalon Class B Common Stock.  If a dividend or distribution payable in

                                       85
<PAGE>
 
Avalon Class A Common Stock is made on the Avalon Class A Common Stock, Avalon
must also make a pro rata and simultaneous dividend or distribution on the
Avalon Class B Common Stock payable in shares of Avalon Class B Common Stock.
Conversely, if a dividend or distribution payable in Avalon Class B Common Stock
is made on the Avalon Class B Common Stock, Avalon must also make a pro rata and
simultaneous dividend or distribution on the Avalon Class A Common Stock payable
in shares of Avalon Class A Common Stock.

Convertibility

     Each share of Avalon Class B Common Stock is convertible at any time, at
the option of and without cost to its holder, into one share of Avalon Class A
Common Stock upon surrender of the certificate or certificates evidencing the
Avalon Class B Common Stock to be converted.  Shares of Avalon Class B Common
Stock are also automatically converted into shares of Avalon Class A Common
Stock on the happening of certain events described in "Restrictions on Transfer
of Avalon Class B Common Stock."  The Avalon Class A Common Stock is not
convertible.

Restrictions on Transfer of Avalon Class B Common Stock

     No person holding shares of Avalon Class B Common Stock (a "Class B
Holder") may transfer such shares, whether by sale, assignment, gift, bequest,
appointment or otherwise, except to Avalon, another Class B Holder or to
Permitted Transferees (as defined in the Avalon Articles) which, in general,
consist of the following:  (i) in the case of a Class B Holder who is a natural
person, such person's spouse, a lineal descendent of a great grandparent of such
Class B Holder, the trustee of a trust for the benefit of one or more of such
Class B Holder, other lineal descendants of a great grandparent of such Class B
Holder or the spouse of such Class B Holder, or an organization established by
such Class B Holder, such Class B Holder's spouse or a lineal descendent of a
great grandparent of such Class B Holder to which contributions are deductible
for federal income, estate and gift tax purposes (a "Charitable Organization");
(ii) in the case of a Class B Holder which is the estate of a deceased Class B
Holder or which is the estate of a bankrupt or insolvent Class B Holder, any
person determined to be a Permitted Transferee of such Class B Holder in
accordance with clause (i) above; (iii) in the case of a Class B Holder that is
a trust or Charitable Organization that received shares of Class B Common Stock
from a Class B Holder in accordance with clause (i) above, such Class B Holder
or any person determined to be a Permitted Transferee of such Class B Holder in
accordance with clause (i) above; and (iv) in the case of a Class B Holder that
is a corporation, any stockholder of such corporation who receives shares of
Avalon Class B Common Stock as a dividend or distribution from such corporation.

     Shares of Avalon Class B Common Stock are freely transferable among
Permitted Transferees, but any other transfer of Avalon Class B Common Stock
results in its automatic conversion into Avalon Class A Common Stock.

<PAGE>
 
Liquidation Rights

     In the event of the dissolution of Avalon, whether voluntary or
involuntary, after payment of all liabilities, the holders of Avalon Class A and
Avalon Class B Common Stock are entitled to share ratably in the assets of
Avalon legally available for distribution to its stockholders.

Other Rights

     In the event of any merger of, consolidation of, share exchange involving,
sale of all or substantially all of the assets of, or any similar transaction
involving, Avalon in which outstanding shares of Avalon Common Stock (other than
shares with respect to which dissenters' rights are perfected pursuant to
Section 1701.85) are to be exchanged for or converted into securities, cash or
other property, the Avalon Class A Common Stock and the Avalon Class B Common
Stock are to be exchangeable for or convertible into the same types and amounts
of consideration.

     The holders of Avalon Class A and Avalon Class B Common Stock are not
entitled to preemptive or subscription rights, and there are no redemption or
sinking fund provisions applicable to the Avalon Common Stock.  The holders of
Avalon Common Stock are not subject to further calls or assessments by Avalon.
The Avalon Class A Common Stock and the Avalon Class B Common Stock to be issued
in the Spin-off will be validly issued, fully paid and non-assessable.

     Avalon has applied to list the Avalon Class A Common Stock on the American
Stock Exchange.

Certain Effects of Authorized but Unissued Stock

     After giving effect to the distribution of shares of Avalon Common Stock
contemplated by the Spin-off, the 1,300,000 shares of Avalon Class A Common
Stock reserved for issuance pursuant to the Incentive Plan, and the 1,000,000
shares of Avalon Class A Common Stock reserved for issuance upon conversion of
the Avalon Class B Common Stock, there will be approximately 5,000,000 unissued
and unreserved shares of Avalon Class A Common Stock and approximately 360,000
unissued and unreserved shares of Avalon Class B Common Stock.  These shares may
be utilized for a variety of corporate purposes, including future public
offerings to raise additional capital to facilitate corporate acquisitions.
Except for the reserved shares described above, Avalon does not currently have
any plans to issue additional shares of Avalon Class A or Avalon Class B Common
Stock.

     One of the effects of the existence of unissued and unreserved Avalon Class
A Common Stock and Avalon Class B Common Stock may be to enable the Avalon Board
to render more difficult or to discourage an attempt to obtain control of Avalon
by means of a merger, tender offer, proxy contest or otherwise, and thereby to
protect the continuity of Avalon's management.  If, in the due exercise of its
fiduciary obligations, for example, the Avalon Board were to determine that a
takeover proposal was not in Avalon's best interests, such shares could be
issued 

                                       87

by the Avalon Board without stockholder approval in one or more private
placements or other transactions that might prevent or render more difficult or
costly the completion of the takeover transaction by diluting the voting or
other rights of the proposed acquirer or insurgent stockholder or stockholder
group, by creating a substantial voting block in institutional or other hands
that might undertake to support the position of the incumbent Avalon Board, or
by effecting an acquisition that might complicate or preclude the takeover.

     Although Ohio law and the Avalon Articles would not require stockholder
approval to issue authorized shares, the American Stock Exchange, on which the
Avalon Class A Common Stock is expected to be listed, requires stockholder
approval of certain issuances as a condition of listing the additional shares
or, in some instances, of continued listing of the outstanding shares.

     In addition, certain other provisions of the Avalon Articles and Avalon
Code, which are described below, may have the effect, alone or in combination
with each other or with the existence of authorized but unissued shares of
capital stock, of rendering more difficult or discouraging an acquisition of
Avalon deemed undesirable by the Avalon Board.  See "Certain Anti-Takeover
Provisions of the Articles of Incorporation, Code of Regulations and Ohio Law."

Certain Anti-Takeover Provisions of the Articles of Incorporation,
Code of Regulations and Ohio Law

     The Avalon Articles and Avalon Code contain certain provisions that are
intended to enhance the likelihood of continuity and stability in the
composition of the Avalon Board and in the policies formulated by the Avalon
Board and to discourage an unsolicited takeover of Avalon if the Avalon Board,
in the due exercise of its fiduciary obligations, determines that such a
takeover is not in the best interests of Avalon and its stockholders.  However,
these provisions could have the effect of discouraging certain attempts to
acquire Avalon or remove incumbent management even if some or a majority of
Avalon's stockholders deem such an attempt to be in their best interests.

     Specifically, certain provisions of the Avalon Articles and Avalon Code (i)
deny stockholders the right to call a special stockholders meeting except on the
written request of stockholders holding 50% or more of the outstanding voting
stock; (ii) provide that the number of directors will be not fewer than five nor
more than fifteen, the exact number of directors to be determined from time to
time by resolution adopted by a majority of the directors then in office; (iii)
provide that a director may be removed only for cause by the vote of the holders
of 80% of the outstanding shares of the class of voting stock that elected such
director; (iv) provide that only the Chairman of the Board or the President may
call a special meeting of the Avalon Board, (v) permit vacancies on the Avalon
Board that may occur between annual meetings to be filled only by the Avalon
Board and not by the stockholders; (vi) prohibit the purchase by Avalon of its
own shares from a 10% stockholder (other than the Avalon stockholders
immediately after the Spin-off) in most circumstances for a period of three
years after such stockholder acquires the shares unless approved by the vote of
holders of 80% of the outstanding shares of Avalon entitled to vote: (vii)
prohibit certain mergers, sales of assets, issuances or purchases of securities,
liquidation or dissolution, or reclassifications or recapitalizations involving
certain

                                       88
<PAGE>
 
holders of stock representing 10% or more of the voting power of the then
outstanding shares of Avalon's voting stock, unless such transactions are either
approved by the directors in office prior to the 10% stockholder becoming such
or such 10% stockholder having been such for at least three years and certain
minimum price and form of consideration requirements being met; and (viii)
prohibit amendment of the foregoing unless the holders of at least 80% of the
voting power represented by Avalon's voting stock vote to approve the amendment.

     The minimum price and form of consideration requirements referred to above
with regard to business combinations involving Avalon are designed to protect
all stockholders of Avalon in certain transactions involving two or more steps
by assuring that at least the same price and form of consideration as was paid
in the initial step of such transaction is paid to those stockholders who sell
their shares to an acquiring party in a second or later step in such
transaction.  These provisions do not assure that stockholders will receive a
premium price for their shares in the event of a takeover.  Accordingly, the
Avalon Board is of the view that such provisions would not preclude it from
opposing a future takeover proposal which it believes not to be in the best
interests of Avalon and its stockholders whether or not such proposal purports
to satisfy such minimum price and form of consideration requirements.  See
"Certain Effects of Authorized but Unissued Stock".

     The requirements of a super-majority vote to approve certain corporate
transactions and certain amendments to the Avalon Articles and Avalon Code could
enable a minority of Avalon's stockholders to exercise veto power over such
transactions and amendments.  So long as the Class B Holders (whose shares have
10 votes each) or any other stockholder group own at least 20% of the combined
voting power of outstanding voting stock, they, if they were to act as a group,
will be able to exercise such veto power.

     In addition, as an Ohio corporation, Avalon is subject to certain
provisions of Ohio law that may discourage or render more difficult an
unsolicited takeover of Avalon.  Among these are provisions that (i) require
approval by a majority of disinterested stockholders, given at a special
stockholders meeting, prior to the consummation of any transfer of shares which
would result in the transferee obtaining control of more than one-fifth of the
voting power of an Ohio corporation, or result in a transferee then holding at
least one-fifth of such voting power increasing such voting power to one-third
or more, or result in a transferee then holding at least one-third of such
voting power increasing such voting power to one-half or more; (ii) prohibit
certain mergers, sales of assets, issuances or purchases of securities,
liquidations or dissolutions, or reclassifications of the then outstanding
shares of an Ohio corporation involving certain holders of stock representing
10% or more of the voting power thereof , unless such transactions are either
approved by the directors in office prior to the 10% stockholder becoming such
or such 10% stockholder has been such for at least three years and certain
minimum price and form of consideration requirements are met; and (iii) provide
Ohio corporations a cause of action to recover profits realized under certain
circumstances by persons engaged in "greenmailing" or the sale of securities of
a corporation within 18 months of proposing to acquire such corporation.

Transfer Agent and Registrar

     The transfer agent and registrar for the Avalon Common Stock will be

10005.

Listing and Trading of Shares of Avalon Class A Common Stock

     Application has been made for listing of the Shares on the American Stock
Exchange under the symbol "AWX."

     There is not currently a public market for the Shares.  Prices at which
Shares may trade prior to the Spin-off on a "when-issued" basis (if at all) or
after the Spin-off cannot be predicted.  The prices at which the Avalon Class A
Common Stock will trade will be determined by the marketplace and may be
influenced by many factors including, among others, the depth and liquidity of
the market for Shares, investor perception of Avalon, its prospects and the
industries in which it participates, Avalon's dividend policy and general
economic and market conditions.  See "Risk Factors--Risk Factors Regarding the
Spin-off--Listing and Trading of Avalon Common Stock; No Prior Public Market."

    
     The Shares distributed to AWS stockholders will be freely transferable,
except for Shares received by persons who may be deemed to be "affiliates" of
Avalon under the Securities Act of 1933, as amended (the "Securities Act").
Persons who may be deemed to be affiliates of Avalon after the Spin-off
generally include individuals or entities that control, are controlled by, or
are under common control with, Avalon and may include directors and certain
officers of Avalon, as well as principal stockholders of Avalon.  Persons who
are affiliates of Avalon will be permitted to sell Shares owned by them only
pursuant to an effective registration statement under the Securities Act or an
exemption from the registration requirements of the Securities Act, such as the
exemption afforded by Section 4(1) of the Securities Act or Rule 144 thereunder.
It is not expected that Rule 144 will be available for the sale of Shares by
affiliates until August 13, 1998 (ninety days after the effectiveness of the
Registration Statement).  See "Available Information," "Security Ownership of
Avalon--Security Ownership of Certain Beneficial Owners" and "Security Ownership
of Avalon--Security Ownership of Directors and Executive Officers."
     
Dividend Policy

     The dividend policy of Avalon will be determined by the Avalon Board.  The
future payment of dividends will depend on business decisions that will be made
by the Avalon Board from time to time based on the results of operations and
financial condition of Avalon and such other business considerations as the
Avalon Board considers relevant.  The Avalon Board currently anticipates that
any Avalon earnings will be retained for use in its business and does not intend
to pay cash dividends on the Avalon Common Stock in the foreseeable future.

                   LIABILITY AND INDEMNIFICATION OF DIRECTORS
                             AND OFFICERS OF AVALON

     The Ohio General Corporation Law empowers a corporation to indemnify a
director, officer, employee or agent of the corporation or someone who was
serving at the corporation's request in a similar capacity in another entity.
Non-derivative suits and derivative suits are dealt with separately by the
statute.

     Ohio Revised Code Section 1701.13(E)(1) applies to non-derivative suits and
provides that an Ohio corporation may indemnify or agree to indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, other than an action by or in the right of the
corporation, by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation in a similar capacity for another corporation,
domestic or foreign , nonprofit or for-profit, or for  a partnership, joint
venture, trust or other enterprise.

     Ohio Revised Code Section 1701.13(E)(2) applies to indemnification for
derivative liability and permits a corporation to indemnify or agree to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed derivative action or derivative suit, by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation or is or was serving at the request of the corporation
in a similar capacity for another corporation, domestic or foreign, nonprofit or
for-profit, or for a partnership, joint venture, trust or other enterprise.  A
corporation may only indemnify against expenses, including attorney's fees,
actually and reasonably incurred by an indemnified party in connection with the
defense or settlement of such an action or suit if such party acted in good
faith and in a manner such indemnified party reasonably believed to be in or not
opposed to the best interests of such corporation.

     Article Seventh of the Avalon Articles provides for indemnification of
Avalon's officers, directors and employees to the fullest extent permitted or
required by law.

     In the Merger Agreement, USA Waste has agreed (i) that the indemnification
provisions of AWS's articles of incorporation will not be changed for a period
of six years, (ii) that after the Closing Date it will indemnify each present
and former director, officer, employee and agent of AWS or any of its
subsidiaries to the fullest extent permitted under applicable law; and (iii) to
keep in place any policies of directors' and officers' liability insurance
covering any of the persons described in clause (ii) for up to a year after the
Closing Date.  See "The Transactions--The Merger and the Merger Agreement--
Indemnification."

                             STOCKHOLDER PROPOSALS

          If the Transactions are consummated, there will be no annual meeting
of the stockholders of AWS in 1998 (the "1998 AWS Annual Meeting").  If the
Transactions are not consummated, the 1998 AWS Annual Meeting will occur on a
date in 1998 that has not yet been determined.

                                       91
<PAGE>
     
With respect to the 1998 AWS Annual Meeting, stockholder proposals will be
timely for purposes of Rule 14a-8 under the Exchange Act, if they are received a
reasonable time before AWS begins to solicit proxies with respect to the 1998
AWS Annual Meeting. AWS intends to treat any stockholder proposal that is
submitted on or before June 30, 1998 as timely (and any stockholder proposal
submitted thereafter as untimely) for purposes of Rule 14a-8 and the 1998 AWS
Annual Meeting. Stockholder proposals are required to satisfy a number of
requirements, in addition to timeliness, in order to be includable in a
company's proxy statement under Rule 14a-8 under the Exchange Act.
     
          The AWS Code of Regulations provides that only matters which could
properly be considered at a special meeting may be considered at an annual
meeting.  The AWS Code of Regulations does not contain provisions addressing
nominating procedures or procedures for bringing other business before a
stockholders' meeting by a stockholder.  In the absence of such provisions,
nominating procedures and procedures for bringing other business before a
stockholders' meeting are governed by Regulation 14A under the Exchange Act and
applicable Ohio law.

                         REPRESENTATIVES OF ACCOUNTANTS

          AWS does not expect representatives of KPMG Peat Marwick to be present
at the Special Meeting or to otherwise be available to respond to questions
presented at the Special Meeting.

                     Notes to Combined Financial Statements

Note 1.  Description of the Business

The accompanying combined financial statements include certain subsidiaries of
American Waste Services, Inc. ("AWS") which will be contributed to Avalon
Holdings Corporation ("Avalon" or "Company"). AWS will contribute to Avalon its
transportation subsidiaries,  technical environmental services subsidiaries,
waste disposal brokerage and management subsidiary, and golf course and related
subsidiaries, (collectively the "Avalon Business").

In addition to such subsidiaries, on the date of the Spin-off, AWS will make a
capital contribution of certain other assets, principally the headquarters of
AWS and certain intercompany accounts receivable. In connection with the
contribution, Avalon will assume certain liabilities of AWS, including without
limitation, any liabilities relating to the termination of employment of certain
employees of AWS and any costs and potential liabilities relating to the legal
proceeding captioned Werbowsky vs. American Waste Services, Inc., et al.  (see
                     ---------------------------------------------------      
Note 8). These amounts have not been included in the combined financial
statements of the Avalon Business and are subject to change based upon (i) the
actual balances at the date of the Spin-off and (ii) adjustments pursuant to the
terms of the Merger Agreement.  The amounts of such assets and liabilities at
December 31, 1997 were as follows (in thousands):

</TABLE>

All of the outstanding shares of common stock of Avalon will then be distributed
to the stockholders of AWS (the "Spin-off").  Avalon will then be an independent
entity (see Note 11).

The Avalon Business will be reflected in Avalon's financial statements at AWS's
historical cost.

The financial information included does not reflect the financial position and
results of operations of Avalon in the future or what these amounts would have
been if it had been a separate, stand-alone entity during the periods presented.

Note 2.  Summary of Significant Accounting Policies

The significant accounting policies of Avalon and its subsidiaries which are
summarized below are consistent with generally accepted accounting principles
and reflect practices appropriate to the businesses in which they operate.  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Principles of combination

The combined financial statements include the accounts of the Avalon Business
including all wholly owned subsidiaries.  All significant intercompany accounts
and transactions have been eliminated in consolidation.

Cash and cash equivalents

Cash and cash equivalents include money market instruments and other highly
liquid investments that are stated at cost which approximates market value.
Such investments, which mature in three months or less from date of purchase,
are considered to be cash equivalents for purposes of the combined statements of
cash flows.  The balance of such short-term investments was $660,000 and
$511,000 at December 31, 1997 and 1996, respectively.

Financial instruments

The fair value of financial instruments consisting of cash, cash equivalents,
receivables, obligations under accounts payable and debt instruments, is based
on interest rates that are expected to be available to Avalon.  At December 31,
1997 and 1996, the fair

                                      F-6
<PAGE>
 
value of these financial instruments approximated carrying value.

Property and equipment

All property and equipment is stated at cost and depreciated using the straight-
line method over the estimated useful life of the asset which varies from 10 to
20 years for land improvements; 5 to 50 years in the case of buildings and
improvements; and from 3 to 10 years for machinery and equipment, transportation
equipment and vehicles, and office furniture and equipment.

Major additions and improvements are charged to the property and equipment
accounts while replacements, maintenance and repairs which do not improve or
extend the life of the respective asset are expensed currently.  The cost of
assets retired or otherwise disposed of and the related accumulated depreciation
is eliminated from the accounts in the year of disposal.  Gains or losses
resulting from disposals of property and equipment are credited or charged to
operations currently.  Interest costs are capitalized on significant projects of
development or expansion and other construction (see Note 5).

Costs in excess of fair market value of net assets
of acquired businesses

The costs in excess of fair market value of net assets of acquired businesses is
amortized on a straight-line basis over 25 years.  Amortization of these costs
was $172,000 in 1997, $172,000 in 1996 and $798,000 in 1995.  Accumulated
amortization at December 31, 1997 and 1996 was $4,625,000 and $4,453,000,
respectively.  During the fourth quarter of 1995 in accordance with Avalon's
asset impairment accounting policy, a portion of the costs in excess of fair
market value of net assets of acquired businesses was written off (see Note 3).

Other intangible assets

Included in the balance of "Other assets, net" are other intangible assets of
$132,000 and $54,000 at December 31, 1997 and 1996, respectively.  In the fourth
quarter of 1995 the intrastate operating authorities relating to the
transportation operations were written off (see Note 3).  Amortization of other
intangible assets in 1997, 1996 and 1995 was $14,000, $9,000 and $46,000,
respectively.

Allocated income taxes

Income taxes are accounted for under the asset and liability method.  Deferred
tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards.  Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled.  The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

The Avalon Business operations were included in the consolidated Federal and
state income tax returns of AWS.  The income tax provisions and tax liabilities
have been allocated to the Avalon Business as if it had been a stand-alone
company filing separate tax returns.


Revenue recognition

The Avalon Business recognizes revenue for transportation services on the date
of delivery.  Revenue for waste disposal brokerage and management services and
technical environmental services, excluding laboratory services, is recognized
as services are performed, while revenue for laboratory services is recognized
when the service is completed.  On contracts where the percentage-of-completion
method is used, revenue is recognized for a portion of the total contract
revenue, in the proportion that costs incurred bear to management's estimate of
total contract costs to be incurred, commencing when progress reaches a point
where experience is sufficient to estimate final results with reasonable
accuracy.  Earnings and costs on contracts are subject to revision throughout
the term of the contract, and any required revisions are made in the periods in
which revisions become known.  Provision is made for the full amount of
anticipated losses in the period in which they are determinable.

Costs and estimated earnings in excess of billings on uncompleted contracts
represent revenues recognized on contracts for which billings will be presented
in accordance with contract provisions.  Such revenues are generally expected to
be billed and collected within one year.

Asset impairments

In the fourth quarter of 1995, the Avalon Business adopted Financial Accounting
Standards Board Statement No. 121 entitled "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of" which was not
significantly different from the Avalon Business's previous asset impairment
accounting policy.  The Avalon Business periodically reviews the carrying

                                      F-7
<PAGE>
 
value of certain of its assets in relation to historical results, current
business conditions and trends to identify potential situations in which the
carrying value of assets may not be recoverable. If such reviews indicate that
the carrying value of such assets may not be recoverable, Avalon would estimate
the undiscounted sum of the expected future cash flows of such assets to
determine if such sum is less than the carrying value of such assets to
ascertain if a permanent impairment exists. If a permanent impairment exists,
the Avalon Business would determine the fair value by using quoted market
prices, if available, for such assets, or if quoted market prices are not
available, the Avalon Business would discount the expected future cash flows of
such assets.

Selling, general and administrative expense

Certain selling, general and administrative expenses have been allocated to the
Avalon Business.  The amounts allocated were $1,709,000 in 1997, $1,704,000 in
1996 and $1,705,000 in 1995.  These costs represent costs of AWS allocated to
the Avalon Business and are not representative of what these costs would have
been if Avalon had been operating on an independent basis.  Management estimates
that such costs would increase by approximately $1,900,000 per year on a stand-
alone basis.

Note 3.  Impairment of Long-lived Assets

In 1995, in accordance with the Avalon Business's asset impairment accounting
policy, the Avalon Business performed  an analysis for impairment of certain
long-lived assets.  As described in the following paragraphs, such evaluation
indicated asset impairments at the Avalon Business's technical environmental
services businesses, and transportation operations.

In 1990, AWS acquired the technical environmental services businesses and
certain transportation operations.  The amounts paid by AWS to purchase these
operations were based upon historical financial results, market conditions
and/or expectations at the time they were acquired.  Significant changes have
occurred in the environmental industry over the last number of years and the
financial performance of these operations had significantly deteriorated since
their acquisition as a result of, among other things, market conditions and
increased competition.  During 1995, in accordance with the Avalon Business's
asset impairment accounting policy, the Avalon Business evaluated the costs in
excess of fair market value of net assets of the technical environmental
services companies and the transportation operations to determine if the
carrying values of such assets were recoverable.

The costs in excess of fair market value of net assets of the technical
environmental services companies were not identified with any long-lived assets
or intangibles at the time of acquisition.  Therefore, the Avalon Business
evaluated the recoverability of such costs in accordance with the Avalon
Business's asset impairment accounting policy and Accounting Principles Board
Opinion No. 17 "Intangible Assets."  To ascertain whether a permanent impairment
existed, the Avalon Business estimated the undiscounted sum of the expected
future after-tax operating income of the technical services companies excluding
amortization of costs in excess of fair market value of net assets to determine
if such sum was less than the carrying value of such costs in excess of fair
market value of net assets, which had a remaining useful life of 20 years.  The
evaluation performed indicated the existence of an impairment and the Avalon
Business determined the fair value and measured the extent of the impairment by
discounting the expected future after-tax operating income excluding
amortization of costs in excess of fair market value of net assets at AWS's
incremental borrowing rate of 8.875%.  As a result, in the fourth quarter of
1995 the Avalon Business recorded an adjustment of $10,106,000 to the carrying
value of the costs in excess of fair market value of net assets.  The adjustment
is included in the Combined Statements of Operations for 1995 under the caption
"Write-down of costs in excess of fair market value of net assets of acquired
businesses and other intangibles."

The recoverability of the costs in excess of fair market value of net assets of
the transportation operations was evaluated in accordance with the Avalon
Business's asset impairment accounting policy and Financial Accounting Standards
Board Statement No. 121, because these costs could be identified with long-lived
assets and other intangible assets.  To ascertain if a permanent impairment
existed, the Avalon Business estimated the undiscounted sum of the expected
future cash flows of the identified assets to determine if such sum was less
than the carrying value of such identified assets.  The evaluation performed
indicated the existence of an impairment and the Avalon Business measured the
extent of the impairment by determining the fair value of the long-lived assets
based upon quoted market prices.  As a result, in the fourth quarter of

                                      F-8
<PAGE>
 
1995, the Avalon Business recorded an adjustment to the carrying value of the
costs in excess of fair market value of net assets and other intangible assets
of $2,194,000 and $720,000, respectively. The adjustments are included in the
Combined Statements of Operations for 1995 under the caption "Write-down of
costs in excess of fair market value of net assets of acquired businesses and
other intangibles." In addition, in 1995 Avalon wrote off $292,000 of property
and equipment. Such amount is included in the Combined Statements of Operations
for 1995 under the caption "Other income (expense), net".

</TABLE>

Aggregate annual maturities of the long-term debt total $230,000, $106,000,
$106,000, $106,000 and $106,000, for the years 1998 through 2002, respectively.

During August 1995, a subsidiary of Avalon borrowed $1,350,000 from a bank to
refinance a previous loan and to finance the construction of a banquet facility.
Proceeds from the new loan were used to repay the remaining unpaid principal
balance of the previous loan which was approximately $850,000.  The new loan is
repayable in equal monthly installments over an initial term of 12.75 years and
provides for interest at a variable rate of 3/4% over the bank's prime rate with
an interest rate ceiling of 8% per annum until March 22, 1998.  Thereafter, the
maximum interest rate will be 9.5% per annum.  The golf course property together
with the pro shop, restaurant facility and banquet facility serve as collateral
securing repayment of this indebtedness.

Interest costs related to significant projects of development or expansion and
other construction are capitalized.  Interest costs capitalized totaled
$-0-, $-0- and $6,000 in 1997, 1996 and 1995, respectively.  Total interest
costs incurred by Avalon totaled $118,000, $141,000 and $172,000 in 1997, 1996
and 1995, respectively.  Interest payments in 1997, 1996 and 1995 were $119,000,
$143,000 and $169,000, respectively.


Note 6.  Income Taxes

The Avalon Business operations were included in the consolidated Federal and
state income tax returns of AWS.  The income tax provisions and tax liabilities
have been allocated to the Avalon Business as if it had been a stand-alone
company filing separate tax returns.

Income (loss) before income taxes for each of the three years ended December 31,
1997 was subject to taxation under United States jurisdictions only.

The provisions (benefits) for income taxes charged to operations consist of the

The Company made income tax payments to state taxing authorities of $82,000,
$99,000 and $57,000 in 1997, 1996 and 1995,  respectively, and payments to AWS
for federal income tax purposes in the amounts of $-0-, $1,126,000 and $-0- in
1997, 1996 and 1995, respectively.

Note 7.  Retirement Benefits

AWS sponsors a defined contribution profit sharing plan that is a qualified tax
deferred benefit plan under Section 401(k) of the Internal Revenue Code (the
"Plan").  The Avalon Business participates in such plan.  Substantially all
employees are eligible to participate in the Plan.  The Plan provides for
employer contributions equal to 4% of each participant's annual compensation.
In addition, discretionary contributions may be made by the employer from time
to time in an amount determined by AWS's Board of Directors.  Mandatory
contributions are fully vested immediately while discretionary contributions
vest on a graduated basis and become 100% vested after six years of service.
Plan participants may also contribute a portion of their annual compensation to
the Plan, subject to maximums imposed by the Internal Revenue Code and related
regulations.  Costs charged to operations for the Avalon Business contributions
were $363,000, $350,000 and $358,000 for the years 1997, 1996 and 1995,
respectively. AWS may make all or a portion of its contributions in the form of
its Class A Common Stock and 2,500,000 shares have been reserved for this
purpose.  The liability for Avalon Business contributions for 1996 and 1995 was
satisfied by the contribution of AWS Class A Common Stock.

Note 8.  Legal Matters

On or about October 3, 1991, one shareholder owning 100 shares of AWS Class A
Common Stock brought suit against AWS and others on behalf of himself and a
purported class of other stockholders in the United States District Court for
the Southern District of New York.  The suit, which was transferred to the
District Court for the Northern District of Ohio, alleges that AWS, the
signatories to the registration statement filed with the Securities and Exchange
Commission during October 1990, and AWS's underwriters violated federal
securities laws in connection with AWS's public offering of six million shares
of Class A Common Stock in October 1990.  Among other things, the suit alleges
misrepresentations and failures to disclose allegedly material information
concerning the nature of AWS's market; the size of AWS's market; AWS's failure
to disclose that its landfills were located within a 50-mile radius of each
other in Ohio, thus making AWS especially vulnerable to local conditions and
competition; AWS's failure to set forth the present and imminent competition;
and AWS's growth.  The plaintiff seeks damages in an unspecified amount alleged
to have arisen in part from the decline in the price of AWS's stock following
the public offering, and rescission.

On September 26, 1997 the Court granted the defendants' motion for Summary
Judgment and dismissed plaintiff's case.  On October 25, 1997, pursuant to the
federal rules of appellate procedure, plaintiff filed a notice of appeal.  Such
appeal is currently pending and AWS intends to vigorously defend the Court's
order.  Avalon has assumed any liability relating to this proceeding and has
agreed to indemnify AWS with respect thereto.

                                      F-10
<PAGE>
 
In September 1995, certain subsidiaries of Avalon were informed that they had
been identified as potentially responsible parties by the Indiana Department of
Environmental Management with respect to a Fulton County, Indiana, hazardous
waste disposal facility which is subject to remedial action under Indiana
environmental laws.  Such identification is based upon the subsidiaries having
been involved in the transportation of hazardous substances to the facility.
These transportation activities occurred prior to the acquisition of such
subsidiaries by AWS.  During the third quarter of 1997 Avalon's subsidiaries
became parties to an Agreed Order for Remedial Investigation/Capital Feasibility
Study and the Four County Landfill Site Participation Agreement ("Participation
Agreement").  A large number of waste generators and other waste transportation
and disposal companies have also been identified as responsible or potentially
responsible parties with respect to this facility.  Because the relevant law
provides for joint and several liability among the responsible parties, any one
of them, including Avalon's subsidiaries, could be assessed the entire cost of
the remediation, although this is unlikely.  Currently, no remedy has been
selected, and the extent of any liability of any of Avalon's subsidiaries is
currently unknown.

When Avalon concludes that it is probable that a liability has been incurred
with respect to a site, a provision is made in Avalon's financial statements for
Avalon's best estimate of the liability based on management's judgment and
experience, information available from regulatory agencies, and the number,
financial resources and relative degree of responsibility of other potentially
responsible parties who are jointly and severally liable for remediation of that
site as well as the typical allocation of costs among such parties.  If a range
of possible outcomes is estimated and no amount within the range appears to be a
better estimate than any other, then Avalon provides for the minimum amount
within the range, in accordance with generally accepted accounting principles.
As such, Avalon accrued a liability of approximately $941,000 in the fourth
quarter of 1995 relating to this matter.  Such amount is included in the
Combined Statements of Operations for 1995 under the caption "Cost of
Operations."

Avalon's estimates are revised, as deemed necessary, as additional information
becomes known.  Avalon anticipates obtaining additional information by reason
of, among other things, having entered into the Participation Agreement.  While
the measurement of environmental liabilities is inherently difficult and the
possibility remains that technological, regulatory or enforcement developments,
the results of environmental studies or other factors could materially alter
Avalon's expectations at any time, Avalon does not anticipate that the amount of
any such revisions will have a material adverse effect on it.

In the ordinary course of conducting its business, Avalon also becomes involved
in lawsuits, administrative proceedings and governmental investigations,
including those relating to environmental matters.  Some of these proceedings
may result in fines, penalties or judgments being assessed against Avalon which,
from time to time, may have an impact on its business and financial condition.
Avalon does not believe that such pending proceedings, individually, or in the
aggregate, would have a material adverse effect on it.

Note 9.  Lease Commitments

Avalon leases certain office facilities, vehicles, machinery and equipment.
Future commitments under long-term, noncancellable operating leases at December
31, 1997 are as follows (in thousands):

Rental expense included in the combined statements of operations amounted to
$1,724,000 in 1997, $1,265,000 in 1996, and $1,360,000 in 1995.

Note 10.  Business Segment Information

Avalon's primary business segment provides transportation services that include
transportation of hazardous and nonhazardous waste as well as general and bulk
commodities.  The technical environmental services segment provides
environmental consulting, engineering, site assessments, analytical laboratory,
remediation services and operates and manages a captive landfill for an
industrial customer. The waste disposal brokerage and management services
segment provides disposal brokerage and management services for both hazardous
and nonhazardous waste.  Other businesses include the operation of a public golf
course and related operations.  Avalon does not have significant

                                      F-11
<PAGE>
 
operations located outside the United States and, accordingly, geographical
segment information is not presented.

The transportation services segment obtained approximately $5 million, $4.5
million and $4.8 million of its net operating revenue from AWS's landfill
subsidiaries in 1997, 1996 and 1995, respectively.  The other Avalon segments
did not have significant transactions with the AWS landfill subsidiaries in
1997, 1996 and 1995.

Segment operating income reflects the results of operations of each business
segment before income taxes, interest income and expense, and items of a general
nature not readily allocable to a separate segment (see Note 3).

The technical environmental services segment, the waste brokerage and management
services segment and a portion of the transportation services segment were
included as part of the integrated waste management and environmental services
segment in AWS's historical segment reporting.  The remaining portion of the
transportation services segment was included in the transportation of general
and bulk commodities segment in AWS's historical segment reporting.

The net operating revenues of the transportation services segment included in
the transportation of general and bulk commodities segment of AWS's historical
segment reporting amounted to $13.2 million, $12.2 million and $12.6 million in
1997, 1996 and 1995, respectively.  Operating income for 1997 and 1996 was $.7
million and $6. million, respectively, and in 1995 an operating loss of $1.3
million was incurred.

Identifiable assets are the total assets used in the operation of each business
segment.  Business segment information is as follows (in thousands):

Note 11.  Subsequent Events

On the date of the Spin-off, AWS will distribute all of the outstanding shares
of capital stock of Avalon to the holders of AWS Common Stock on a pro rata and
corresponding basis which will be recorded as a distribution of retained
earnings and capital surplus by AWS.  Holders of AWS Class A Common Stock will
receive one share of Avalon Class A Common Stock, $.01 par value for every eight
shares of AWS Class A Common Stock held, and holders of AWS Class B Common Stock
will receive one share of Avalon Holdings Class B Common Stock, $.01 par value
for every eight shares of AWS Class B Common Stock held.

The number and identity of stockholders of Avalon immediately after the
distribution will be the same as the number and identity of stockholders of AWS.

AWS and Avalon have agreed to enter into a mutually acceptable agreement under
which Avalon will provide to AWS, if requested, certain services and facilities,
including administrative and bookkeeping services to allow for a smooth
transition subsequent to the Spin-off.

AWS and Avalon have agreed that after the Spin-off, service agreements with
third-party customers which, by reason of the Spin-off would require services to
be provided by both AWS and Avalon will continue to be performed by both AWS and
Avalon, as appropriate, and in a manner consistent with historical practices.

AWS and Avalon have agreed to enter into a Tax Allocation Agreement which
provides for the allocation between AWS and Avalon of all responsibilities,
liabilities and benefits relating to or affecting taxes paid or payable by
either AWS or Avalon, as the case may be, for all taxable periods, whether
beginning before, on or after the Spin-off and to provide for certain other
matters.  The Tax Allocation Agreement also provides mechanisms for cooperation
in preparing and filing returns, payment of tax liabilities, and tax refunds and
carryback items and further provides for certain indemnification between AWS and
Avalon for tax and related liabilities which might result due to the Spin-off.

The Shareholders and Board of Directors of American Waste Services, Inc.

We have audited the accompanying combined balance sheets of the Avalon Business

the related combined statements of operations, combined equity and cash flows
for each of the years in the three-year period ended December 31, 1997.  These
combined financial statements are the responsibility of the management of
American Waste Services, Inc.  Our responsibility is to express an opinion on
these combined financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Avalon as of

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

held, and holders of AWS Class B Common Stock will receive one share of Avalon

matters.  The Tax Allocation Agreement also provides mechanisms for cooperation
in preparing and filing returns, payment of tax liabilities, and tax refunds and
carryback items and further provides for certain indemnification between AWS and
Avalon for tax and related liabilities which might result due to the Spin-off.

Note 4.  Transitional Services Agreement

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following unaudited Pro Forma Combined Balance Sheet of the Avalon
Business as of December 31, 1997 and the unaudited Pro Forma Combined Statement
of Operations for the year ended December 31, 1997 have been prepared as if the
transactions had occurred on January 1, 1997 and to reflect:  (i) the
contribution by AWS to Avalon of the Avalon Business and other certain assets
and the assumption by Avalon of certain liabilities of AWS; (ii) the
distribution to the holders of the outstanding shares of AWS Common Stock of all
outstanding shares of capital stock of Avalon on a pro rata and corresponding
basis; (iii) the merger and transactions contemplated by the Agreement and Plan
of Merger dated as of February 6, 1998 entered into by and among American Waste
Services, Inc., C&S Ohio Corp. and USA Waste Services, Inc.; and (iv) certain
other adjustments as reflected in the footnotes.  The accounting for the
foregoing represents a reorganization of companies under common control and,
accordingly, all assets and liabilities will be reflected at their historical
cost basis.

     The unaudited Pro Forma Combined Balance Sheet has been prepared as if the
transactions occurred on December 31, 1997; the unaudited Pro Forma Combined
Statement of Operations has been prepared as if the transactions occurred on
January 1, 1997.  The pro forma financial information set forth below is
unaudited and not necessarily indicative of the results that would actually have
occurred if the transactions had been consummated as of December 31, 1997, or
January 1, 1997, or results which may be obtained in the future.

     The pro forma adjustments, as described in the notes to the Pro Forma
Combined Balance Sheet and notes to the Pro Forma Combined Statement of
Operations, are based on available information and upon certain assumptions that
management believes are reasonable.  The unaudited Pro Forma Combined Financial
Information should be read in conjunction with the Avalon Business financial
statements, including the related notes thereto.

Notes to Unaudited Pro Forma Combined Statement of Operations

The following pro forma adjustments are incorporated in the unaudited pro forma
combined statement of operations:

a)  To eliminate the results of operations of Eagle Fidelity Insurance Company,
a subsidiary of AWS being contributed to Avalon, the sole function of which was
to provide insurance to the AWS landfill subsidiaries for financial assurance
requirements of the Ohio Environmental Protection Agency.  Such coverages will
not be provided subsequent to the Spin-off, resulting in the cessation of
operations of Eagle Fidelity (in thousands).


 Net operating revenues.......................... $(245)
 Cost of operations..............................    (2)
 Selling, general and administrative expense.....   (47)
 Interest income.................................    (7)
 Provision for income taxes......................   (71)
                                                  ----- 
   Net income ................................... $(132)
                                                  ===== 

b) To reflect pro forma tax adjustment. No income tax benefit is provided due
to the inability of Avalon to carry back a net operating loss. Further, it is
considered more likely than not that any deferred tax asset related to the net
operating loss carryforward would not be realized (in thousands).

 Provision for income taxes...................... $ 209

c)  On the date of the Spin-off, AWS will distribute all of the outstanding
shares of capital stock of Avalon to the holders of AWS Common Stock on a pro
rata and corresponding basis which will be recorded as a distribution of
retained earnings and capital surplus by AWS.  Holders of AWS Class A Common
Stock will receive one share of Avalon Class A Common Stock, $.01 par value for
every eight shares of AWS Class A Common Stock held, and holders of AWS Class B
Common Stock will receive one share of Avalon Holdings Class B Common Stock,
$.01 par value for every eight shares of AWS Class B Common Stock held.  The
weighted average number of shares outstanding for 1997 is 3,797,913.

d)  Avalon will incur additional costs and expenses as a result of operating as
an independent company.  Management estimates that selling, general and
administrative expenses would increase by approximately $1.9 million per year
and cost of operations would increase by approximately $.6 million per year.

Avalon will also incur severance costs for terminated employees as a result of
the Spin-off.  Management estimates these costs to be approximately $.3 million.

e)  AWS and Avalon have agreed to enter into a mutually acceptable agreement
under which Avalon will provide to AWS, if requested, certain services and
facilities, including administrative and bookkeeping services, to allow for a
smooth transition subsequent to the Spin-off.

AWS and Avalon have agreed that after the Spin-off, service agreements with
third-party customers which, by reason of the Spin-off would require services to
be provided by both AWS and Avalon, will continue to be performed by both AWS
and Avalon, as appropriate, and in a manner consistent with historical
practices.

AWS and Avalon have agreed to enter into a Tax Allocation Agreement which
provides for the allocation between AWS and Avalon of all responsibilities,
liabilities and benefits relating to or affecting taxes paid or payable by
either AWS or Avalon, as the case may be, for all taxable periods, whether
beginning before, on or after the Spin-off and to provide for certain other
matters.  The Tax Allocation Agreement also provides mechanisms for cooperation
in preparing and filing returns, payment of tax liabilities, and tax refunds and
carryback items, and further provides for certain indemnification between AWS
and Avalon for tax and related liabilities which might result due to the Spin-
off.

None of the aforementioned agreements resulted in any pro forma adjustments.

April 20, 1998



Mr. Ronald E. Klingle
Chairman and Chief Executive Officer
American Waste Services, Inc.
One American Way
Warren, Ohio  44484

Dear Mr. Klingle:

At your request, on behalf of American Waste Services, Inc. (the "Company"), we
have analyzed certain financial information regarding Avalon Holdings
Corporation (hereinafter sometimes referred to as "Avalon") as set forth herein,
and submit this letter on our findings.

We understand as follows:  The Company has entered into a definitive Agreement
and Plan of Merger pursuant to which the Company will merge with a wholly owned
subsidiary of USA Waste Services, Inc. ("USA Waste").  Prior to the merger, the
Company will contribute to Avalon certain real property and financial assets of
the Company and its transportation, waste disposal brokerage and management,
technical services and golf course subsidiaries not being acquired by USA Waste.
After Avalon's Class A common stock has been registered with the Securities and
Exchange Commission under the Securities Exchange Act of 1934, as amended, the
outstanding capital stock of Avalon, will be distributed in the form of a
dividend from the Company on a corresponding and pro rata basis to the Company's
shareholders prior to the merger being consummated (the "Spin-Off").  The
dividend will constitute a taxable disposition by the Company and a taxable
distribution to the Company's shareholders.  All such transactions and other
related transactions disclosed to Houlihan, Lokey, Howard & Zukin Financial
Advisors, Inc. ("Houlihan Lokey") are referred to collectively herein as the
"Transaction".
<PAGE>
 

The purpose of this letter is to express an opinion (the "Opinion") on the fair
market value, as of March 31, 1998, of the capital stock of Avalon to serve as a
valuation basis for establishing the amount of any taxable gain resulting from
the Spin-Off.

Avalon will be engaged in the transportation of hazardous and non-hazardous
waste, waste disposal brokerage and management, environmental, technical
services, and ownership and operation of a golf course and related operations.
Corporate headquarters and facilities are located primarily in Warren, Ohio,
Canfield, Ohio, and Export, Pennsylvania. Ownership of the Company is
represented by 25,300,608 shares of no par value Class A Common Stock ("Class A
Common Stock") and 5,124,558 shares of no par value Class B Common Stock ("Class
B Common Stock") issued and outstanding as of the date of the Spin-Off. On the
date of the Spin-Off, holders of the Company's Class A Common Stock will receive
one share of Avalon's no par value Class A Common Stock for every eight shares
of the Company's Class A Common Stock held, and holders of the Company's Class B
Common Stock will receive one share of Avalon's no par value Class B Common
Stock for every eight shares of the Company's Class B Common Stock held,
resulting in a post Spin-Off capitalization for Avalon of approximately
3,162,576 shares of Avalon's Class A Common Stock and approximately 640,569
shares of Avalon's Class B Common Stock.

The term "fair market value," as used herein, is defined as the amount at which
the Avalon capital stock would change hands between a willing buyer and a
willing seller, each having reasonable knowledge of all relevant facts, neither
being under any compulsion to act, with equity to both.  Furthermore, for
purposes of this letter it will be assumed that the Avalon capital stock has
been fully distributed to the Company's stockholders, that the Avalon Class A
Common Stock is trading on an established market and that information concerning
Avalon has been widely disseminated.

It is Houlihan Lokey's understanding, upon which it is relying, that the
Company's Board of Directors and any other recipient of the Opinion will consult
with and rely solely upon their own legal counsel with respect to said
definition.  No representation is made herein, or directly or indirectly by the
Opinion, as to any legal matter or as to the sufficiency of said definition for
any purpose other than setting forth the scope of Houlihan Lokey's Opinion
hereunder.

In connection with this Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.
Among other things, we have:

1.   met with certain members of the senior management of the Company to discuss
     the operations, financial condition, future prospects and projected
     operations and performance of Avalon;

2.  visited certain facilities and business offices of the Company;
<PAGE>
 

3.   reviewed the Company's annual reports to shareholders and on Form 10-K for
     the five fiscal years ended December 31, 1997;

4.   reviewed the unaudited pro forma combined and combining financial
     statements for the businesses to be contributed to Avalon for the five year
     period ended December 31, 1997;

5.   reviewed forecasts and projections prepared by the Company's management
     with respect to Avalon for the years ended December 31, 1998 through 2002;

6.   reviewed the historical market prices and trading volume for the Company's
     publicly traded securities;

7.   reviewed certain other publicly available financial data for certain
     companies that we deem comparable to Avalon;

8.   reviewed a preliminary proxy statement of the Company with respect to,
     among other things, the Spin-Off filed with the SEC on March 16, 1998;

9.   reviewed a copy of the Agreement and Plan of Merger By and Among USA Waste
     Services, Inc., C&S Ohio Corp. And American Waste Services, Inc. and the
     Contribution and Distribution Agreement By and Between American Waste
     Services, Inc. and Avalon Holdings Corporation;

10.  reviewed a copy of the Tax Allocation Agreement, and Non-Competition
     Agreement relating to the Transaction; and

11.  conducted such other studies, analyses and inquiries as we have deemed
     appropriate.

We have relied upon and assumed, without independent verification, that the
financial forecasts and projections provided to us have been reasonably prepared
and reflect the best currently available estimates of the future financial
results and condition of Avalon, and that there has been no material change in
the assets, financial condition, business or prospects of Avalon since the date
of the most recent financial statements made available to us.

We have not independently verified the accuracy and completeness of the
information supplied to us with respect to Avalon and do not assume any
responsibility with respect to it.  We have not made any physical inspection or
independent appraisal of any of the properties or assets of Avalon.

In our analysis of Avalon, we have taken into consideration the income- and
cash-generating capability of Avalon.  Typically, an investor contemplating an
investment in a company with income-and cash-generating capability similar to
Avalon will evaluate the risks of and returns on
<PAGE>
 
its investment on a going-concern basis. Accordingly, after due consideration of
other appropriate and generally accepted valuation methodologies, the value of
the common stock of Avalon has been determined primarily on the basis of
capitalization of earnings and discounted cash flow approaches.

Furthermore, we valued Avalon as a going-concern, meaning that the underlying
tangible assets of the Company are presumed, in the absence of a qualified
appraisal of such assets, to attain their highest values as integral components
of a business entity in continued operation and that liquidation of said assets
would likely diminish the value of the whole to the shareholders and creditors
of Avalon.

All valuation methodologies that estimate the worth of an enterprise as a going-
concern are predicated on numerous assumptions pertaining to prospective
economic and operating conditions.  Our opinion is necessarily based on
business, economic, market and other conditions as they exist and can be
evaluated by us as of the valuation date. Unanticipated events and circumstances
may occur and actual results may vary from those assumed. The variations may be
material.

Based upon the investigation, premises, provisos, and analyses outlined above,
it is our opinion that, as of March 31, 1998, the fair market value of the
capital stock of Avalon Holdings Corporation, is reasonable stated in the amount
of $30,425,160 or $8.00 per share based on 3,162,576 shares of Class A Common
and 640,569 shares of Class B Common issued and outstanding after the Spin-Off.

In accordance with recognized professional ethics, our fees for this service are
not contingent upon the opinion expressed herein, and neither Houlihan, Lokey,
Howard & Zukin Financial Advisors, Inc. nor any of its employees has a present
or intended financial interest in the Company or Avalon.

The Opinion, expressed above, is advisory in nature only.  The abbreviated
format of the Opinion, as requested, may not conform to specific guidelines set
forth in the Uniform Standards of Professional Appraisal Practice (U.S.P.A.P.)
pertaining only to the narrative content of reports.  Nonetheless, our work
files contain all necessary analyses and documentation to prepare a conforming
narrative report, if so requested, and our work product is otherwise in
compliance with applicable standards of U.S.P.A.P.

     AGREEMENT AND PLAN OF MERGER, dated as of February 6, 1998 (the
"Agreement"), by and among USA Waste Services, Inc., a Delaware corporation
("USA Waste"), C&S Ohio Corp., an Ohio corporation and a wholly owned subsidiary
of USA Waste ("Mergerco"), and American Waste Services, Inc., an Ohio
corporation ("AWS").

                                 W I T N E S S E T H:
                                 ------------------- 

     WHEREAS, the respective Boards of Directors of USA Waste, Mergerco and AWS
deem it advisable and in the best interests of their respective stockholders
that USA Waste indirectly acquire the non-hazardous solid waste landfills owned
or operated, the refuse collection services provided, and the landfill gas
collection and sales business conducted (collectively, the "Retained Business")
by certain of AWS's subsidiaries (the "Retained Subsidiaries"), pursuant to the
terms and conditions set forth in this Agreement; and

     WHEREAS, as set forth in Section 4.1, USA Waste, AWS and a company to be
formed by AWS ("Avalon") will enter into a contribution and distribution
agreement substantially in the form of Exhibit A hereto (the "Distribution
                                       ---------                          
Agreement"), pursuant to which AWS's assets, other than those used primarily in
the Retained Business, will be contributed to and certain related liabilities
will be assumed by Avalon (the "Contribution"), and all outstanding shares of
capital stock of Avalon will be distributed (the "Distribution") to the
stockholders of AWS as provided in the Distribution Agreement, in order to
divest AWS of the businesses and operations that USA Waste is unwilling to
acquire; and

     WHEREAS, as set forth in Section 4.1, USA Waste, AWS and Avalon will enter
into a tax allocation agreement substantially in the form of Exhibit B hereto
                                                             ---------       
(the "Tax Allocation Agreement" and, together with the Distribution Agreement,
the "Ancillary Agreements"); and

     WHEREAS, the respective Boards of Directors of USA Waste, Mergerco and AWS
have determined that, following the Distribution, the merger of Mergerco with
and into AWS (the "Merger"), with AWS surviving as a wholly owned subsidiary of
USA Waste, pursuant to the terms and conditions set forth in this Agreement,
would be in the best interests of their respective stockholders; and

     WHEREAS, in connection with the Merger and as an inducement to USA Waste to
enter into this Agreement, USA Waste, AWS and certain stockholders of AWS have
executed as of the date hereof voting agreements and irrevocable proxies,
substantially in the form of Exhibit C hereto (each, a "Voting Agreement"), in
                             ---------                                        
favor of USA Waste with respect to the voting of shares of capital stock of AWS
held or to be held by such stockholders for approval and adoption of this
Agreement.

(the "Merger Filing"). The Merger Filing shall be made simultaneously with or as
soon as practicable after the closing of the transactions contemplated by this
Agreement in accordance with Section 3.5. The parties acknowledge that it is

                    THE SURVIVING CORPORATION AND USA WASTE

     Section 2.1 Articles of Incorporation. The Articles of Incorporation of AWS

Incorporation of the Surviving Corporation after the Effective Time, and
thereafter may be amended in accordance with their terms and as provided by the
OGCL.

     Section 2.2 Regulations. The Regulations of AWS as in effect immediately
prior to the Effective Time shall be the Regulations of the Surviving
Corporation after the Effective Time, and thereafter may be amended in
accordance with their terms and as provided by the Articles of Incorporation of
the Surviving Corporation and the OGCL.

     Section 2.3 Directors. The directors of the Surviving Corporation shall be
as designated in Schedule 2.3, and such directors shall serve in accordance with

                                  ARTICLE III
                              CONVERSION OF SHARES

     Section 3.1 Conversion of AWS Shares in the Merger. At the Effective Time,
by virtue of the Merger and without any action on the part of any holder of any
capital stock of AWS:

          (a)  each outstanding share of AWS's Class A Common Stock, no par
value ("Class A Common Stock"), and each outstanding share of AWS's Class B
Common Stock, no par value ("Class B Common Stock" and, together with the Class
A Common Stock, "AWS Common Stock"), shall, subject to Sections 3.1(b), 3.3 and
3.4, be converted into the right to receive, without interest, cash in an amount
equal to Four Dollars ($4.00) per share (the "Merger Consideration"); and

          (b)  each share of capital stock of AWS, if any, held in treasury by
AWS or held by any subsidiary of AWS immediately prior to the Effective Time
shall be canceled and shall cease to exist from and after the Effective Time
without any payment being made therefor ("Canceled Shares").

     Section 3.2 Conversion of Mergerco Shares. At the Effective Time, by virtue
of the Merger and without any action on the part of USA Waste as the sole
stockholder of Mergerco, each issued and outstanding share of common stock, par
value $.01 per share, of Mergerco ("Mergerco Common Stock") shall be converted
into one share of common stock, no par value, of the Surviving Corporation.

     Section 3.3   Delivery of Merger Consideration.

          (a)  Prior to the Effective Time, USA Waste shall select a bank or
trust company reasonably acceptable to AWS to act as the paying agent for the
Merger (the "Paying Agent").  At or prior to the Effective Time, USA Waste shall
deposit or cause to be deposited in trust with the Paying Agent an amount equal
to the Merger Consideration multiplied by the number of outstanding shares of
AWS Common Stock (excluding Canceled Shares) (the "Payment Fund").  Out of the
Payment Fund, the Paying Agent shall make the payments referred to in Section
3.3(c).  The Payment Fund shall not be used for any other purpose.  The Payment
Fund may be invested by the Paying Agent, as directed by the Surviving
Corporation, in (i) obligations of or guaranteed by the United States, (ii)
commercial paper rated A-1, P-1, A-2 or P-2, (iii) certificates of deposit, bank
repurchase agreements and bankers' acceptances of any bank or trust company
organized under federal law or under any law of any state of the United

                                      B-3
<PAGE>
 
States or of the District of Columbia which has capital, surplus and undivided
profits of at least One Billion Dollars ($1,000,000,000) and (iv) money market
funds that are invested solely in any such securities. Any net earnings with
respect thereto shall first be used to pay the fees and expenses of the Paying
Agent. To the extent that such net earnings are not so used, then such remaining
amount, determined at the end of each month until the remainder of the Payment
Fund is paid to the Surviving Corporation in accordance with Section 3.3(f),
shall be paid within 10 days of the end of each such month to the Surviving
Corporation and Avalon in equal portions. After the remainder of the Payment
Fund has been paid to the Surviving Corporation in accordance with the terms of
Section 3.3(f), Avalon shall not be entitled to subsequent earnings thereon.

          (b)  As soon as reasonably practicable after the Effective Time, the
Paying Agent shall mail to each holder of record of AWS Common Stock as of the
Effective Time a letter of transmittal for return to the Paying Agent (the
"Paying Agent Letter"): (i) notifying of the effectiveness of the Merger; (ii)
providing instructions for effecting the surrender and exchange of the
certificates representing AWS Common Stock (the "Certificates") for the Merger
Consideration; (iii) specifying that delivery shall be effected, and risk of
loss of the Certificates shall pass, only upon delivery of Certificates to the
Paying Agent; and (iv) including such other provisions as USA Waste and AWS
agree on prior to the Effective Time.

          (c)  USA Waste and the Surviving Corporation shall cause the Paying
Agent to pay to the holder of any Certificate as soon as is practicable after
receipt of such Certificate, or in lieu of such Certificate an affidavit of lost
share certificate (including a customary indemnity against loss) in form and
substance reasonably satisfactory to USA Waste, together with the Paying Agent
Letter, duly executed, and any other item specified by the Paying Agent Letter,
an amount equal to the product of (i) the number of shares of AWS Common Stock
represented by the Certificate so surrendered multiplied by (ii) the Merger
Consideration, less any applicable withholding taxes.  No interest shall accrue
or be paid on any cash payable upon the surrender of any Certificate.  Each
Certificate surrendered in accordance with the provisions of this Section 3.3(c)
shall be canceled forthwith.

          (d)  In the event of any transfer of ownership of shares of AWS Common
Stock which is not registered in the transfer records of AWS, the Merger
Consideration may be paid to the transferee only if (i) the Certificate
representing such shares of AWS Common Stock is surrendered to the Paying Agent
in accordance with Section 3.3(c), properly endorsed for transfer or accompanied
by appropriate and properly endorsed stock powers, and is otherwise in proper
form to effect such transfer, (ii) the person requesting such transfer pays to
the Paying Agent any transfer or other taxes payable by reason of such transfer
or establishes to the satisfaction of the Paying Agent that such taxes have been
paid or are not required to be paid, and (iii) such person establishes to the
satisfaction of USA Waste that such transfer would not violate any applicable
federal or state securities laws.

          (e)  At and after the Effective Time, each holder of a Certificate
that represented issued and outstanding shares of AWS Common Stock immediately
prior to the

                                      B-4
<PAGE>
 
Effective Time shall cease to have any rights as a stockholder of AWS, except
for the right to surrender his or her Certificate in exchange for the Merger
Consideration and except as otherwise provided by applicable law, and no
transfer of shares of AWS Common Stock shall be made on the stock transfer books
of the Surviving Corporation.

          (f)  Any portion of the Payment Fund that remains unclaimed as of the
end of the month in which the first anniversary of  the Effective Time occurs
shall be paid to the Surviving Corporation upon demand, except as provided in
the next to last sentence of Section 3.3(a).  Any holders of Certificates who
have not theretofore complied with this Section 3.3 shall thereafter look only
to the Surviving Corporation and USA Waste for payment (subject to applicable
abandoned property, escheat and similar laws) of their claim for the Merger
Consideration, without interest thereon.  Notwithstanding the foregoing, neither
USA Waste, the Surviving Corporation nor the Paying Agent shall be liable to a
holder of a Certificate for any Merger Consideration properly delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

     Section 3.4 Dissenting Shares. Notwithstanding anything in this Agreement
to the contrary, shares of AWS Common Stock ("Dissenting Shares") that are held
by stockholders who shall not have voted such shares in favor of approval and
adoption of the Merger and this Agreement and who, not later than 10 days after
the date on which the vote of the stockholders on the approval and adoption of
the Merger and this Agreement is taken, shall have delivered to AWS or the
Surviving Corporation a written demand for payment of the fair cash value of
such shares in the manner provided in Section 1701.85 of the OGCL ("Section
1701.85") shall not be converted into the right to receive the Merger
Consideration, and the holders thereof shall be entitled to payment of the fair
cash value of such Dissenting Shares in accordance with the provisions of
Section 1701.85; provided, however, that (i) if any holder of Dissenting Shares
does not comply with Section 1701.85 (unless the Surviving Corporation waives
such failure); (ii) if any holder of Dissenting Shares subsequently withdraws
such holder's demand for payment of the fair cash value of such Dissenting
Shares (with the consent of the Surviving Corporation), or (iii) if the
Surviving Corporation and the holders of Dissenting Shares have not come to an
agreement as to the fair cash value per share, and neither any holder of
Dissenting Shares nor the Surviving Corporation has filed or joined in a
complaint under division (B) of Section 1701.85 within the period provided in
that division, then the right and obligation of the holder or holders (as the
case may be) of Dissenting Shares to receive the fair cash value of the
Dissenting Shares as to which the holder or holders seek relief under Section
1701.85, and the right and obligation of the Surviving Corporation to purchase
such Dissenting Shares and to pay fair cash value for such Dissenting Shares,
shall terminate, and such Dissenting Shares shall thereupon be deemed to have
been converted into the right to receive the Merger Consideration as provided in
Section 3.1 and shall have only such rights as provided under this Agreement and
the OGCL.

     Section 3.5 Closing. The closing (the "Closing") of the transactions
contemplated by this Agreement shall take place at a location mutually agreeable
to USA Waste and AWS as soon as practicable (and in any event within 15 business
days) following the date on which the last of

                                      B-5
<PAGE>
 
the conditions set forth in Article IX is fulfilled or waived, or at such other
time and place as USA Waste and AWS shall agree. The date on which the Closing
occurs is referred to in this Agreement as the "Closing Date."

     Section 3.6   Pre-Closing Financial Transactions.

          (a)  General Procedure.   Attached hereto as Schedule 3.6 is a
spreadsheet that, among other things, includes the pro forma balance sheet of
AWS and the Retained Subsidiaries as of October 31, 1997 and illustrates the
procedure for determining (i) the amount of the Contributed Net Intercompany
Receivables (as defined in Section 3.6(c)(iii)); (ii) the amount of the primary
(and, if necessary, the secondary) loan to be made by USA Waste to AWS (as
described in Sections 3.6(c) and 3.6(e)); (iii) the Net Working Capital (as
defined in Section 3.6(e)) adjustment; and (iv) the types and amounts of pre-
Distribution payments contemplated by this Agreement.  In illustrating such
procedure, Schedule 3.6 reflects estimated amounts for the Transaction
Liabilities (as defined in Section 3.6(c)), an estimate of the Distribution Tax
(as defined in Section 3.8) and an estimate of the Net Intercompany Receivables
(as defined in Section 3.6(c)(iii)).

          (b)  Final Balance Sheet.  Prior to the Distribution Date (as defined
in the Distribution Agreement), the Final Balance Sheet (as defined in Section
3.7) will be substituted for the pro forma balance sheet of AWS and the Retained
Subsidiaries as of October 31, 1997 in the spreadsheet on Schedule 3.6, and the
final amounts for previously estimated items (labeled as Items (B) through (Q)
on Schedule 3.6) will be determined.  Any reference to any capital letter in
parenthesis, as in the immediately preceding sentence, in this Section 3.6 is a
reference to an item on Schedule 3.6.

          (c)  Primary USA Loan.  Subject to the limitations set forth in
Section 3.6(g), USA Waste shall, immediately prior to the Contribution, lend to
AWS, pursuant to a promissory note in a form to be agreed upon by AWS and USA
Waste (a "Promissory Note"), an amount (C) (the "Primary USA Loan") equal to (A)
$150,000,000 minus (B) the product of the Merger Consideration multiplied by the
number of shares of AWS Common Stock outstanding as of such time (excluding all
Canceled Shares).  AWS shall use the funds from the Primary USA Loan solely as
illustrated on Schedule 3.6, and solely as more fully described as follows:

               (i)  First, AWS shall use those funds to pay or cause to be paid
     the following obligations (collectively, the "Transaction Liabilities") of
     AWS and the Retained Subsidiaries determined as of the Distribution Date:

                    (x)  The (D) transaction costs incurred by AWS in connection
                    with the Merger, the Contribution and the Distribution (the
                    "Transaction Costs"), including legal, accounting and
                    valuation fees, the fees and costs payable to the Investment
                    Banker (as defined in Section 3.8), the costs of printing
                    and mailing the Proxy Statement (as defined in Section 5.4)
                    and any other documents

                                      B-6
<PAGE>
 
                    distributed to AWS's stockholders in connection with this
                    Agreement, and any filing or registration fees associated
                    therewith;

                    (y)  The amount required to redeem (E) outstanding options
                    to purchase AWS Common Stock in accordance with Section 8.7;
                    and

                    (z)  The amount (F) outstanding under AWS's existing
                    revolving credit facility (the "Credit Facility") as of
                    December 31, 1997, plus any amounts (G) borrowed thereunder
                    since December 31, 1997, the proceeds of which are not used
                    for a purpose primarily attributable to any Retained
                    Subsidiary, plus (H) accrued but unpaid interest thereon
                    from December 31, 1997.

               (ii)  Second, after having made the above payments, AWS shall
     reserve an amount (J) to pay the Distribution Tax when due, which amount is
     to be determined as set forth in Section 3.8.

               (iii)   Third, AWS shall calculate the remaining funds available
     from the Primary USA Loan (K) (the "Remaining Funds") and then shall
     calculate the sum of the obligations owed by any Retained Subsidiary to AWS
     (which shall be treated as positive numbers) and the intercompany
     obligations owed by AWS to any Retained Subsidiary (which shall be treated
     as negative numbers), all of which shall be listed in the row entitled "Net
     Intercompany Balances" on Schedule 3.6.  Such sum is the "Net Intercompany
     Receivables."

                    (x)  If the Remaining Funds are greater than or equal to the
                    sum of the Net Intercompany Receivables, the long-term debt
                    owed by Mahoning Landfill Inc. to AWS (the "MLI Debt"), and
                    any Retained Stock Option Liability (as hereinafter defined)
                    (which shall be treated as a positive number), then an
                    amount equal to the Net Intercompany Receivables shall be
                    deemed contributed to Avalon under the Distribution
                    Agreement as "Contributed Net Intercompany Receivables" for
                    purposes of Section 3.6(e).

                    (y)  If the Remaining Funds are less than the sum of  the
                    Net Intercompany Receivables, the MLI Debt, and any Retained
                    Stock Option Liability (which shall be treated as a positive
                    number), then only such amount of such intercompany
                    obligations owed to AWS equal to the excess of the Remaining
                    Funds over the MLI Debt and any Retained Stock Option
                    Liability shall be deemed contributed to Avalon under the
                    Distribution Agreement as "Contributed Net Intercompany
                    Receivables" for purposes of Section 3.6(e).

                                      B-7
<PAGE>
 
          (d)  Contribution.  Subject to the restrictions set forth in Section
3.6(g), following the final determination of Contributed Net Intercompany
Receivables pursuant to Sections 3.6(c) and 3.6(e) and following the payment of
the Transaction Liabilities by AWS pursuant to Section 3.6(c)(i) and the
reservation for any Distribution Tax as contemplated by Section 3.6(c)(ii), AWS
shall contribute the Contributed Net Intercompany Receivables and the MLI Debt
to Avalon and shall contribute sufficient amounts of Remaining Funds to the
appropriate Retained Subsidiaries for and shall cause such Retained Subsidiaries
to pay Avalon for (L) the Contributed Net Intercompany Receivables and (M) the
MLI Debt.

          (e)  Net Working Capital Adjustment.   Following all the above
adjustments to the Final Balance Sheet, a determination of (Q) the net working
capital of AWS and its Retained Subsidiaries (the "Net Working Capital") is to
be made as follows:  a pro forma consolidated balance sheet (see column 17 of
Schedule 3.6) is to be generated taking into account all such adjustments and
the Net Working Capital is to be calculated by subtracting (P) the current
liabilities (which shall include the water-line liability of Mahoning Landfill
Inc., which is deemed to be equal to $750,000.00) from (O) the current assets on
such balance sheet.  For purposes of the foregoing calculation, the full amount
of the Primary USA Loan shall be deemed to be a long-term liability.

               (i)  If the Net Working Capital so calculated is a positive
     number, then USA Waste will make a "Secondary USA Loan" upon delivery of a
     second Promissory Note from AWS in an amount sufficient for AWS to make and
     AWS shall make an additional cash contribution to Avalon in an amount equal
     to the Net Working Capital as part of the Contribution.

               (ii)  If the Net Working Capital so calculated is a negative
     number, then the amount (L) of Contributed Net Intercompany Receivables to
     be contributed by AWS to Avalon pursuant to Section 3.6(d) will be reduced
     by such number (the "Net Working Capital Deficiency").

To the extent that the net working capital of the Retained Subsidiaries
increases after December 31, 1997, the Surviving Corporation shall have the
benefit of such increase, and to the extent the net working capital of the
Retained Subsidiaries decreases after December 31, 1997, the Surviving
Corporation shall bear such decrease.

          (f)  Retained Stock Option Adjustment.  To the extent that outstanding
stock options exercisable for shares of AWS Common Stock have not been redeemed
by AWS or converted into Avalon Employee Options (as hereinafter defined) in
accordance with Section 8.7 ("Retained Stock Options"), then an aggregate amount
equal to the sum of (i) the difference between the Merger Consideration and the
exercise price of each such Retained Stock Option, (ii) multiplied by the number
of shares of AWS Common Stock for which such Retained Stock Option is
exercisable ("Retained Stock Option Liability") shall be applied as provided in
Section 3.6(c)(iii).  Notwithstanding the foregoing, if the exercise price of
any Retained Stock Option exceeds the Merger Consideration then the Retained
Stock Option Liability with respect to such

                                      B-8
<PAGE>
 
option shall equal the product of $1.00 and the number of shares of AWS Common
Stock for which such Retained Stock Option is exercisable.

          (g)  Limitations.  Notwithstanding anything herein to the contrary, if
the sum of the Transaction Liabilities, the Distribution Tax, the Net Working
Capital Deficiency and the Retained Stock Option Liability is greater than the
amount of the Primary USA Loan, then USA Waste shall not be obligated to
consummate the Merger and shall be entitled to terminate this Agreement and if
USA Waste terminates this Agreement, it shall have no obligation to make the
Primary USA Loan or the Secondary USA Loan.  For purposes of assisting USA Waste
in determining the applicability of this limitation, the Distribution Tax and
Net Working Capital Deficiency shall be calculated as provided herein, and at
least fifteen (15) days prior to the Distribution, AWS shall provide USA Waste
with a good faith estimate of the Transaction Liabilities and the aggregate
Retained Stock Option Liability along with reasonable supporting documentation.

     Section 3.7   Final Balance Sheet.

          (a)  Within 60 days after December 31, 1997, AWS will provide USA
Waste with the unaudited consolidated balance sheet of AWS and the Retained
Subsidiaries as of such date, prepared in accordance with generally accepted
accounting principles applied on a consistent basis and then adjusted as
described below (the "Final Balance Sheet").  The Final Balance Sheet shall be
prepared using the same methods and criteria employed by AWS in connection with
the preparation of the AWS Financial Statements (as defined in Section 6.5)
except as described below, and shall not reflect any revaluation of any assets
or liabilities.  In order to prepare the Final Balance Sheet, the unaudited
consolidated balance sheet of AWS as of December 31, 1997 shall be adjusted in
the same manner as the pro forma balance sheet of AWS as of October 31, 1997 is
adjusted in columns (1) through (10) of Schedule 3.6.  AWS shall provide USA
Waste and its accountants, attorneys and advisors with reasonable access to the
books and records of AWS (including all work papers) to the extent necessary to
verify the Final Balance Sheet.  USA Waste shall have 30 days after receipt of
the Final Balance Sheet to review it and make any good faith objections in
writing to AWS.  If such objections are made to AWS within such period, USA
Waste and AWS shall attempt to resolve the matter or matters in dispute.  If no
objections are made within the time period provided above, the Final Balance
Sheet shall be deemed accepted by USA Waste and shall be final and binding.

          (b)  If disputes with respect to the Final Balance Sheet cannot be
resolved by USA Waste and AWS within 30 days after receipt of USA Waste's
written objections thereto, then the specific matters in dispute shall be
submitted to the Pittsburgh office of Arthur Andersen LLP ("Arthur Andersen"),
which shall render its opinion as to such matters.  Arthur Andersen shall send
to USA Waste and AWS its determination of the specific matters in dispute and
the Final Balance Sheet, adjusted to the extent necessary to be consistent with
that determination, which determination and revised Final Balance Sheet shall be
final and binding on the parties.  The fees and expenses of Arthur Andersen
pursuant to this Section 3.7 shall be shared equally by USA Waste and AWS and
AWS's portion thereof shall be part of the Transaction Costs.

     Section 3.8 Distribution Tax. Prior to the Effective Time, the parties
shall calculate the federal, state and local income, sales, transfer and other
taxes (the "Distribution Tax") which may be incurred by AWS on the taxable gain,
if any, recognized on the Distribution. In calculating the Distribution Tax, USA
Waste and AWS agree to abide by the opinion (the "Valuation") of Houlihan,
Lokey, Howard & Zukin, Inc., an investment banking firm selected by USA Waste
and AWS (the "Investment Banker"), as to the fair market value of Avalon as of
the Distribution Date. After the Investment Banker has delivered the Valuation
to USA Waste and AWS, AWS shall calculate the taxable gain, if any, to AWS
resulting from the Distribution and the resulting federal, state and local
income, sales, transfer and other taxes thereon, using AWS's adjusted tax basis
in its Avalon stock as of the Distribution Date. USA Waste, its counsel and its
independent public accountants shall then have the opportunity to review and
confirm such calculation of the Distribution Tax and, in so doing, shall be
given access to all work papers, books, records and other information in the
possession of AWS and its independent public accountants relevant in the
reasonable judgment of USA Waste to such calculation. Should USA Waste disagree
as to the amount of the Distribution Tax calculated by AWS, then USA Waste and
AWS shall appoint Arthur Andersen to calculate the Distribution Tax based upon
the Valuation, AWS's adjusted tax basis in its Avalon stock and other relevant
information. The calculation by Arthur Andersen of the Distribution Tax shall be
final and binding on USA Waste and AWS. The fees and expenses of Arthur Andersen
in calculating the Distribution Tax shall be shared equally by USA Waste and AWS
and AWS's portion thereof shall be part of the Transaction Costs.

                        CERTAIN PRE-MERGER TRANSACTIONS

     Section 4.1 Ancillary Agreements. Prior to the Distribution, AWS will (a)
execute and deliver the Distribution Agreement and the Tax Allocation Agreement
and (b) cause Avalon to execute and deliver the Distribution Agreement and the
Tax Allocation Agreement.

     Section 4.2 Contribution of Assets and Assumption of Liabilities.
Immediately prior to the Distribution and pursuant to the terms of the
Distribution Agreement, AWS and Avalon will consummate the Contribution.

     Section 4.3 Distribution. At least one day prior to the Closing Date,
pursuant to the terms of the Distribution Agreement, AWS will cause the
Contribution to be consummated and effect the Distribution if all other
conditions to the Closing have been satisfied or waived and certificates to that
effect shall have been delivered (i) to AWS from USA Waste in which USA Waste
has unconditionally agreed to consummate the Merger as of the opening of
business on the next business day, and (ii) to USA Waste from AWS in which AWS
has unconditionally agreed to consummate the Merger as of the opening of
business on the next business day.

the properties owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to

other such failures, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
USA Waste and its subsidiaries, taken as a whole.

     Section 5.2   Authority; Non-Contravention; Approvals.

          (a)  USA Waste and Mergerco each have full corporate power and

enforcement of creditors' rights generally and (ii) general equitable
principles.

          (b)  The execution and delivery of this Agreement by each of USA Waste

both would constitute a default) under, and will not result in the termination
of, accelerate the performance required by, result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,
charge or encumbrance (collectively, "Liens") upon any of the properties or
assets of USA Waste or any

                                      B-11

the transactions contemplated hereby will not result in any violation, conflict,
breach, default, termination, acceleration or creation of Liens under any of the
terms, conditions or provisions described in clauses (i) through (iii) of the
preceding sentence, subject in the case of the terms, conditions and provisions

and provisions described in clauses (ii) and (iii) of the first sentence of this
paragraph (b), are such violations, conflicts, breaches, defaults, terminations,
accelerations or creations of Liens that would not, in the aggregate, have a
material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of USA Waste and its
subsidiaries, taken as a whole.

          (c)  Except for (i) the filings by USA Waste and AWS required by the

Act"), (ii) the making of the Merger Filing with the Secretary of State of the
State of Ohio in connection with the Merger, and (iii) any required filings with
or approvals from applicable state environmental authorities, public service
commissions and public utility commissions (the filings and approvals referred
to in clauses (i) through (iii) are collectively referred to as the "USA Waste

supplements thereto) to be distributed in connection with AWS's meeting of
its stockholders to vote upon this Agreement and the transactions contemplated
hereby (the "Proxy Statement") will, at the time of the mailing of the Proxy
Statement (and any amendments thereof or supplements thereto), and at the time
of the meeting of stockholders of AWS to be held in connection with the
transactions contemplated by this Agreement, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.


                                   ARTICLE VI
                     REPRESENTATIONS AND WARRANTIES OF AWS

     AWS represents and warrants to USA Waste and Mergerco that, except as set
forth in the disclosure schedule dated as of the date hereof and signed by an
authorized officer of AWS (the "AWS Disclosure Schedule"), it being agreed that
disclosure of any item on the AWS Disclosure Schedule shall be deemed to be with
respect to all Sections of this Agreement if the relevance of such item is
reasonably apparent from the face of the AWS Disclosure Schedule:

     Section 6.1 Organization and Qualification. AWS is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Ohio and has the requisite corporate power and authority to own, lease and
operate its assets and properties and to carry on its business as it is now
being conducted. AWS is qualified to do business and is in good standing in each
jurisdiction in which the properties owned, leased or operated by it or the
nature of the business conducted by it makes such qualification necessary,
except where the failure to be so qualified and in good standing would not, when
taken together with all other such failures, have a material adverse effect on
the business, operations, properties, assets, condition (financial or other) or
results of operations of AWS and its subsidiaries, taken as a whole. True,
accurate and complete copies of AWS's Amended and Restated Articles of
Incorporation and Amended and Restated Code of Regulations, in each case as in
effect on the date hereof, including all amendments thereto, have heretofore
been delivered to USA Waste.

     Section 6.2   Capitalization.

          (a)  The authorized capital stock of AWS consists of 70,000,000 shares
of Class A Common Stock, 30,000,000 shares of Class B Common Stock and 2,000,000
shares of preferred stock.  As of December 31, 1997, 25,300,278 shares of Class
A Common Stock, 5,124,888 shares of Class B Common Stock and no shares of such
preferred stock were issued and outstanding.  All of such issued and outstanding
shares are validly issued and are fully paid, nonassessable and free of
preemptive rights.  No subsidiary of AWS holds any shares of the capital stock
of AWS.

          (b)  Except as disclosed in the AWS SEC Reports (as defined in Section
6.5), as of the date hereof there are no outstanding subscriptions, options,
calls, contracts,

                                      B-13
<PAGE>
 
commitments, understandings, restrictions, arrangements, rights or warrants,
including any right of conversion or exchange under any outstanding security,
instrument or other agreement and also including any rights plan or other anti-
takeover agreement, obligating AWS or any subsidiary of AWS to issue, deliver or
sell, or cause to be issued, delivered or sold, additional shares of its capital
stock or obligating AWS or any subsidiary of AWS to grant, extend or enter into
any such agreement or commitment. Each outstanding option or warrant to purchase
AWS Common Stock is listed on the AWS Disclosure Schedule, which sets forth (i)
the name of the holder, (ii) which entity employs the holder, if applicable,
(iii) the number of shares of AWS Common Stock for which such option or warrant
is exercisable and (iv) the exercise price of such option or warrant. There are
no voting trusts, proxies or other agreements or understandings to which AWS or
any subsidiary of AWS is a party or is bound with respect to the voting of any
shares of capital stock of AWS other than the Voting Agreements executed in
connection with this Agreement.

     Section 6.3 Subsidiaries. Each direct and indirect corporate subsidiary of
AWS is duly organized, validly existing and in good standing under the laws of
its jurisdiction of incorporation and has the requisite corporate power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted. Each subsidiary of AWS is qualified
to do business and is in good standing in each jurisdiction in which the
properties owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified and in good standing would not, when taken together with all
such other failures, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
AWS and its subsidiaries, taken as a whole. All of the outstanding shares of
capital stock of each corporate subsidiary of AWS are validly issued, fully
paid, nonassessable and free of preemptive rights and are owned directly or
indirectly by AWS free and clear of any Liens. There are no outstanding
subscriptions, options, calls, warrants, rights, contracts, voting trusts,
proxies or other commitments, understandings, restrictions or arrangements
relating to the issuance, sale, voting, transfer or ownership of, or other
rights with respect to, any shares of capital stock of any corporate subsidiary
of AWS, including any right of conversion or exchange under any outstanding
security, instrument or agreement. Each subsidiary of AWS is listed on Section
6.3 of the AWS Disclosure Schedule. AWS is not the record or beneficial owner of
any interests in any entity other than the subsidiaries so listed.

     Section 6.4   Authority; Non-Contravention; Approvals.

          (a)  AWS has full corporate power and authority to enter into this
Agreement and, subject to obtaining the AWS Stockholders' Approval (as defined
in Section 8.3) and making or obtaining the AWS Required Statutory Approvals (as
defined in Section 6.4(c)), to consummate the transactions contemplated hereby.
This Agreement has been approved by the Board of Directors of AWS, and no other
corporate proceedings on the part of AWS are necessary to authorize the
execution and delivery of this Agreement or, except for the AWS Stockholders'
Approval and the approval of the Contribution and the declaration of the
Distribution by the Board of Directors of AWS, the consummation by AWS of the
transactions

                                      B-14
<PAGE>
 
contemplated hereby. The forms of the Ancillary Agreements have been approved by
the Board of Directors of AWS. This Agreement has been duly executed and
delivered by AWS, and, assuming the due authorization, execution and delivery
hereof by USA Waste and Mergerco, constitutes a valid and legally binding
agreement of AWS enforceable against AWS in accordance with its terms, except
that such enforcement may be subject to (i) bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting or relating to
enforcement of creditors' rights generally and (b) general equitable principles.
Without limitation of the foregoing, each of the covenants and obligations of
AWS set forth in Sections 7.1, 8.1, 8.2, 8.3, 8.5, 8.6, 8.7, 8.8, 8.9 and 8.10
is valid, legally binding and enforceable notwithstanding the absence of the AWS
Stockholders' Approval except that the enforcement thereof may be subject to (i)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting or relating to enforcement of creditors' rights generally and (ii)
general equitable principles.

          (b)  The execution and delivery of this Agreement by AWS do not
violate, conflict with, result in a breach of any provision of, or constitute a
default (or an event which with notice or lapse of time or both would constitute
a default) under, and will not result in the termination of, accelerate the
performance required by, result in a right of termination or acceleration under,

and delivery of this Agreement by AWS or the consummation by AWS of the
transactions contemplated hereby, other than such declarations, filings,
registrations, notices, authorizations, consents and approvals which, if not

material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of AWS and its
subsidiaries, taken as a whole.

in light of the circumstances under which they were made, not misleading. The
audited consolidated financial statements and unaudited interim consolidated
financial statements of AWS included in such reports (collectively, the "AWS
Financial Statements") have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis (except as may be indicated
therein or in the notes thereto) and fairly present the financial position of
AWS and its subsidiaries as of the dates thereof and the results of their
operations and cash flows for the periods then ended, subject, in the case of
the unaudited interim financial statements, to normal year-end audit adjustments

AWS and its subsidiaries, taken as a whole or (ii) will have been discharged or
paid in full prior to the Closing Date, and (c) liabilities and obligations
which are of a nature not required to be reflected in the consolidated financial
statements of AWS and its subsidiaries prepared in accordance with generally
accepted accounting principles consistently applied and which were incurred in
the ordinary course of business.

     Section 6.7 Absence of Certain Changes or Events. Since the date of the
most recent AWS SEC Report that contains consolidated financial statements of
AWS, except as disclosed in the AWS SEC Reports, there has not been any material
adverse change in the business, operations, properties, assets, liabilities,
condition (financial or other) or results of operations of AWS and its
subsidiaries, taken as a whole, except for changes that affect the industries in
which AWS and its subsidiaries operate generally or volume reductions to the
extent arising from business decisions made by existing or potential customers.

     Section 6.8 Litigation. Except as disclosed in the AWS SEC Reports, there
are no Proceedings pending or, to the knowledge of AWS, threatened against,
relating to or affecting AWS or any of its subsidiaries before any court,
governmental department, commission, agency, instrumentality or authority, or
arbitrator that seek to restrain or enjoin the consummation of the Merger or
that could reasonably be expected, either alone or in the aggregate with all
such Proceedings, to have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
AWS and its subsidiaries, taken as a whole. All such Proceedings pending or
threatened against, relating to or affecting AWS or any of its subsidiaries are
set forth in Section 6.8 of the AWS Disclosure Schedule. Except as referred to
in the AWS SEC Reports or disclosed in the AWS Disclosure Schedule, neither AWS
nor any of its subsidiaries is subject to any judgment, decree, injunction or
order of any court, governmental department, commission, agency, instrumentality
or authority, or arbitrator that prohibits or restricts the consummation of the
transactions contemplated hereby or would have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of AWS and its subsidiaries, taken as a whole.

     Section 6.9 Proxy Statement. None of the information to be supplied by AWS
or its subsidiaries for inclusion in the Proxy Statement will, at the time of
the mailing of the Proxy Statement (and any amendments thereof or supplements
thereto), and at the time of the meeting of stockholders of AWS to be held in
connection with the transactions contemplated by this Agreement, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they are made, not misleading. The Proxy
Statement will comply, as of its mailing date, as to form in all material
respects with all applicable laws, including the

given notice of or been charged with any violation of any law, statute, order,
rule, regulation, ordinance or judgment (including, without limitation, any
applicable Environmental Law) of any governmental or regulatory body or
authority, except for violations which, in the aggregate, could not reasonably
be expected to have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
AWS and its subsidiaries, taken as a whole. Except as disclosed in the AWS SEC
Reports, as of the date of this Agreement, to the knowledge of AWS and its
subsidiaries, no investigation or review by any governmental or regulatory body
or authority is pending or threatened nor has any governmental or regulatory
body or authority indicated an intention to conduct the same, other than, in
each case, those the outcome of which, as far as reasonably can be foreseen,
will not have a material adverse effect on the business, operations, properties,
assets, condition (financial or other) or results of operations of AWS and its
subsidiaries taken as a whole. AWS and its Retained Subsidiaries have all
permits, licenses, franchises, variances, exemptions, orders and other
governmental authorizations, consents and approvals necessary to conduct their
businesses as presently conducted, except for permits, licenses, franchises,
variances, exemptions, orders, authorizations, consents and approvals the
absence of which, alone or in the aggregate, would not have a material adverse
effect on the business, operations, properties, assets, condition (financial or
other) or results of operations of AWS and its subsidiaries, taken as a whole
(collectively, the "AWS Permits"). All of the AWS Permits are listed in Section
6.10 of the AWS Disclosure Schedule. AWS and its Retained Subsidiaries are not
in violation of the terms of any AWS Permit, except for violations which, alone
or in the aggregate, would not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other), results of
operations of AWS and its subsidiaries, taken as a whole.

     Section 6.11 Compliance with Agreements. Except as disclosed in the AWS SEC
Reports, AWS and each of its Retained Subsidiaries are not in breach, violation,
or default in the performance or observance of any term or provision, of and no
event has occurred which with lapse of time or action by a third party could
result in a default under (a) the respective charters, bylaws or similar
organizational instruments of AWS or any of its Retained Subsidiaries or (b) any
contract, commitment, agreement, indenture, mortgage, loan agreement, note,
lease, bond, license, approval or other instrument to which AWS or any of its
Retained Subsidiaries is a party or by which any of them is bound or to which
any of their property is subject, which breaches, violations and defaults, in
the case of clause (b) above, would have, in the aggregate, a material adverse
effect on the business, operations, properties, assets, condition (financial or
other) or results of operations of AWS and its subsidiaries, taken as a whole.

          (a)  AWS and its subsidiaries have duly filed (or there has been filed
on their behalf) with the appropriate taxing authority all Tax Returns (as
hereinafter defined) required to be filed by them on or prior to the date hereof
other than any Tax Returns, the failure to file which would not, individually or
in the aggregate, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
AWS and its subsidiaries, taken as a whole.  The Tax Returns filed by or on
behalf of AWS and its subsidiaries are true, correct and complete in all
material respects and all Taxes shown thereon have been duly paid in full or

periods ending at or prior to the date of such balance sheet have been
determined in accordance with generally accepted accounting principles, and
there is no material liability for Taxes for any period beginning after such
date other than Taxes arising in the ordinary course of business.  There are no
Liens for Taxes upon any property or assets of AWS or any Retained Subsidiary
thereof, except for Liens for Taxes not yet due or Taxes being contested in good
faith and adequately reserved against in accordance with generally accepted
accounting principles.  There are no unresolved issues of law or fact arising
out of a notice of deficiency, proposed deficiency or assessment from the
Internal Revenue Service ("IRS") or any other governmental taxing authority with
respect to Taxes of AWS or any of its subsidiaries which, singly or in the
aggregate, would reasonably be expected to have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of AWS and its subsidiaries, taken as a whole.  Neither
AWS nor its subsidiaries have waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency other than waivers and extensions of time which are no longer in
effect.  Neither AWS nor any of its subsidiaries is a party to any agreement
providing for the allocation or sharing of Taxes with any entity that is not,

held, acquired or to be acquired by any of them, filed a consent to the
application of Section 341(f) of the Internal Revenue Code of 1986, as amended
(the "Code").

satisfy any condition thereof or by a subsequent amendment thereto or a failure
to amend, except that it may be necessary to make additional amendments
retroactively to maintain the "qualified" status of such AWS Plans and the
period for making any such retroactive amendment has not expired, and (iv) to
the knowledge of AWS and its subsidiaries, there are no material pending,
threatened or anticipated claims involving any of the AWS Plans or any fiduciary

<PAGE>
 
expected to have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
AWS and its subsidiaries, taken as a whole.

involving the collection, interim storage,

<PAGE>

above.

     Section 6.17 Title to Assets. AWS and each of its Retained Subsidiaries has
good and marketable title in fee simple to all real property owned by it and
good title to all its leasehold interests and other properties, as reflected in
the most recent balance sheet included in the AWS Financial Statements, except
for properties that have been disposed of in the ordinary course of business
since the date of such balance sheet, free and clear of all Liens of any nature
whatsoever, except (i) the Lien for current Taxes, payments of which are not yet
delinquent, (ii) such imperfections in title and easements and encumbrances, if
any, are not substantial in character, amount or extent and do not materially
detract from the value or interfere with the present use of the property subject
thereto or affected thereby, or otherwise materially impair AWS's business
operations (in the manner presently carried on by AWS), or (iii) as disclosed in
the AWS SEC Reports, and except for such matters which, individually or in the
aggregate, could not reasonably be expected to have a material adverse effect on
the business, operations, properties, assets, condition (financial or other) or
results of operations of AWS and its subsidiaries, taken as a whole. All leases
under which AWS leases any real or personal property are in good standing, valid
and effective in accordance with their respective terms and there is not, under
any of such leases, any existing default or event which with notice or lapse of
time or both would become a default other than defaults under such leases which
in the aggregate will not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other) or results of
operations of AWS and its subsidiaries, taken as a whole. All real property
owned or leased by AWS or any of the Retained Subsidiaries is listed in Section
6.17 of the AWS Disclosure Schedule, and all items of personal property valued
in excess of $5,000 owned by AWS or any of its Retained Subsidiaries not
reflected on the fixed asset list previously provided to USA Waste are listed in
Section 6.17 of the AWS Disclosure Schedule. The assets owned or leased by the
Retained Subsidiaries at the Effective Time, together with the rights of AWS and
the Retained Subsidiaries under the Distribution Agreement and the rights that
the parties currently anticipate that AWS will have under the Transitional
Services Agreement (as defined in the Distribution Agreement) to be entered into
between AWS and Avalon, will enable AWS to operate the Retained Business in a
manner consistent with past practice.

     Section 6.18   Retained Business.

          (a)  Attached hereto as Section 6.18 of the AWS Disclosure Schedule is
an unaudited pro forma consolidated balance sheet of the Retained Business at
October 31, 1997 (the "Retained Business Balance Sheet").  The Retained Business
Balance Sheet has been prepared on a pro forma basis giving effect to the
Distribution in accordance with generally accepted accounting principles (except
as expressly stated therein) on a basis consistent with the

                                      B-23
<PAGE>
 
AWS Financial Statements, and fairly presents in all material respects (subject
to the absence of footnotes and normal, recurring audit adjustments) the assets
and liabilities of the Retained Business as at the date thereof after giving
effect to the Distribution (assuming the Distribution occurred on October 31,
1997).

          (b)  AWS or one of the Retained Subsidiaries directly or indirectly
owns or has a valid leasehold interest in the assets reflected on the Retained
Business Balance Sheet, free and clear of any Liens, except (i) as may be
reflected in the Retained Business Balance Sheet, (ii) Liens for Taxes, payments
of which were not delinquent as of October 31, 1997, (iii) such imperfections in
title and easements and encumbrances, if any, as are not substantial in
character, amount or extent and do not materially detract from the value or
interfere with the present use of the property subject thereto or affected
thereby or otherwise materially impair the operation of the Retained Business
(in the manner it is presently conducted), or (iv) as disclosed in the AWS SEC
Reports, and except for such matters which, individually or in the aggregate,
could not reasonably be expected to have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of the Retained Business, taken as a whole.  All of the
buildings and material tangible personal property owned or leased by AWS and its
Retained Subsidiaries that are included in the Retained Business are in good
working condition (normal wear and tear excepted) and are suitable in all
material respects for the purposes for which they are being used.  AWS has
reasonable relationships with its customers, employees and others having
business dealings with the Retained Business.

     Section 6.19 Certain Payments. Neither AWS, any of its subsidiaries, nor
any director, officer, employee, agent, representative or other person acting

with the consummation of the transactions under this Agreement to allow USA
Waste or the Surviving Corporation to conduct the business of AWS and its
Retained Subsidiaries as currently conducted.

     Section 7.2 Control of AWS's Operations. Nothing contained in this
Agreement shall give to USA Waste, directly or indirectly, any right to control
or direct AWS's or any subsidiary's operations prior to the Effective Time.
Prior to the Effective Time, AWS shall exercise, consistent with the terms and
conditions of this Agreement, complete control and supervision of such
operations.

     Section 7.3   Acquisition Transactions.

          (a)  After the date hereof and prior to the Effective Time or earlier
termination of this Agreement, AWS shall not, and shall not permit any of its
subsidiaries to, initiate, solicit, negotiate, encourage or provide confidential
information to facilitate, and AWS shall, and shall cause each of its
subsidiaries to, cause any officer, director or employee of, or any attorney,
accountant, investment banker, financial advisor or other agent retained by it,
not to initiate, solicit, negotiate, encourage or provide non-public or
confidential information to facilitate, any proposal or offer to acquire all or
any substantial part of the business and properties of AWS or any capital stock
of AWS, whether by merger, purchase of assets, tender offer or otherwise,
whether for cash, securities or any other consideration or combination thereof
(such transactions being referred to herein as "Acquisition Transactions").

<PAGE>
 
          (b)  Notwithstanding the provisions of paragraph (a) above and without
being a breach or violation thereof:  (i) AWS may, in response to an unsolicited
written offer or proposal with respect to a potential or proposed Acquisition
Transaction ("Acquisition Proposal"), furnish (subject to the execution of a
confidentiality agreement substantially similar to the confidentiality
provisions of the Confidentiality Agreement, executed by USA Waste in connection
herewith) confidential or non-public information concerning its business,
properties or assets to a financially capable corporation, partnership, person
or other entity or group (a "Potential Acquiror") and negotiate with such
Potential Acquiror if (x) the Board of Directors of AWS in good faith determines
that such Acquisition Proposal (if consummated pursuant to its terms) would
result in a transaction more favorable to AWS's stockholders than the Merger and
(y) based upon advice of its outside legal counsel, its Board of Directors
determines in good faith that the failure to provide such confidential or non-
public information to such Potential Acquiror would be reasonably likely to
constitute a breach of its fiduciary duty to its stockholders (any such
Acquisition Proposal meeting the conditions of clauses (x) and (y) being
referred to as a "Superior Proposal").  (ii) AWS's Board of Directors may take
and disclose to AWS's stockholders a position with respect to a tender offer by
a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the
Exchange Act or may make such other disclosures to AWS's stockholders which, as
advised by outside counsel, is required under applicable law.

          (c)  AWS shall immediately notify USA Waste after receipt of any
Acquisition Proposal or any request for non-public information relating to AWS
or its subsidiaries in connection with an Acquisition Proposal or for access to
the properties, books or records of AWS or any subsidiary by any person or
entity that informs the Board of Directors of AWS or such subsidiary that it is
considering making, or has made, an Acquisition Proposal.  Such notice to USA
Waste shall be made orally and in writing and shall indicate in reasonable
detail the identity of the offeror and the terms and conditions of such
proposal, inquiry or contact.

                             ADDITIONAL AGREEMENTS

     Section 8.1   Access to Information.

          (a)  AWS and its subsidiaries shall afford to USA Waste and Mergerco
and their accountants, counsel, financial advisors and other representatives
(the "USA Waste Representatives") full access during normal business hours
throughout the period prior to the Effective Time to all of their respective
properties (but not to conduct soil, groundwater, ambient air or other
environmental testing or analyses), books, contracts, personnel, representatives
of or contacts with governmental or regulatory authorities, agencies or bodies,
and records (including, but not limited to, Tax Returns and any and all records
or documents which are within the possession of governmental or regulatory
authorities, agencies or bodies and the disclosure of which AWS and its
subsidiaries can facilitate or control) with respect to the Retained Business
and any Liabilities of AWS and, during such period, shall furnish promptly to
USA Waste (i) a copy of each report, schedule or other document filed or
received by any of them pursuant to the

                                      B-28
<PAGE>
 
requirements of federal or state securities laws or filed by any of them with
the SEC in connection with the transactions contemplated by this Agreement or
which may have a material effect on their businesses, properties or personnel,
(ii) a copy of any financial statements of AWS and its subsidiaries when
prepared, and (iii) such other information concerning their businesses,
properties and personnel as USA Waste or Mergerco, as the case may be, shall
reasonably request. USA Waste and its subsidiaries shall hold, and shall use
their reasonable best efforts to cause the USA Waste Representatives to hold, in
strict confidence all non-public documents and information furnished to USA
Waste and Mergerco in connection with the transactions contemplated by this
Agreement, except that (i) USA Waste and Mergerco may disclose such information
as may be necessary in connection with seeking the USA Waste Required Statutory
Approvals, and (ii) each of USA Waste and Mergerco may disclose any information
that it is required by law or judicial or administrative order to disclose.

          (b)  In the event that this Agreement is terminated in accordance with
its terms, USA Waste and Mergerco shall promptly redeliver to AWS all non-public
material provided pursuant to this Section 8.1 and shall not retain any copies,
extracts or other reproductions in whole or in part of such written material.
In such event, all documents, memoranda, notes and other writings prepared by
USA Waste based on the information in such material shall be destroyed (and USA
Waste shall use commercially reasonable efforts to cause all USA Waste
Representatives to similarly destroy their documents, memoranda and notes), and
such destruction (and reasonable best efforts) shall be certified in writing by
an authorized officer supervising such destruction.

     Section 8.2 Proxy Statement. AWS shall file with the SEC as soon as is
reasonably practicable after the date hereof the Proxy Statement.

     Section 8.3 Stockholders' Approvals. Subject to the fiduciary duties of the
Board of Directors of AWS under applicable law, AWS shall, as promptly as
practicable, submit this Agreement and the transactions contemplated hereby for
the approval and adoption of its stockholders at a meeting of stockholders (the
"AWS Stockholders' Approval"). Subject to the fiduciary duties of the Board of
Directors of AWS under applicable law, such meeting of stockholders shall be
held as soon as practicable. Subject to the fiduciary duties of the Board of
Directors of AWS under applicable law, AWS shall, through its Board of
Directors, recommend to its stockholders approval of the transactions
contemplated by this Agreement.

     Section 8.4   Expenses and Fees.

          (a)  All costs and expenses incurred in connection with this Agreement
and the transactions contemplated hereby shall be paid by the party incurring
such expenses.

          (b)  AWS agrees to pay to USA Waste a fee equal to Seven Million Five
Hundred Thousand Dollars ($7,500,000) if (i) AWS terminates this Agreement
pursuant to clause  (vi) or (vii) of Section 10.1(a);  (ii) USA Waste terminates
this Agreement pursuant to clause (iv) of Section 10.1(b); or (iii) AWS
terminates this Agreement pursuant to

                                      B-29
<PAGE>
 
Section 10.1(a)(iv) or USA Waste terminates this Agreement pursuant to Section
10.1(b)(v) and within seven months of such termination AWS enters into an
agreement for, or a letter of intent with respect to, an Acquisition Transaction
with a per share consideration for the AWS Common Stock greater than the sum of
$4.00 plus the per share value of the Distribution (as calculated from the
Valuation); provided, however, that the payment of the fee payable pursuant to
clause (iii) need not be made unless and until the consummation of such
Acquisition Transaction. For purposes of clause (iii) of the preceding sentence,
the per share consideration for an Acquisition Transaction shall be equal to the
sum of the cash amount per share payable pursuant thereto and the fair market
value per share (as agreed to in good faith by AWS and USA Waste or, absent such
agreement, as determined by the Investment Banker) of any non-cash consideration
payable pursuant thereto. This provision shall, to the extent applicable,
survive the termination of this Agreement.

     Section 8.5   Agreement to Cooperate.

          (a)  Subject to the terms and conditions herein provided and subject
to the fiduciary duties of the respective boards of directors of AWS and USA
Waste, each of the parties hereto shall use commercially reasonable efforts to
take, or cause to be taken, all action and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
including using its reasonable efforts to obtain all necessary or appropriate
waivers, consents or approvals of third parties required in order to preserve
material contractual relationships of AWS and its Retained Subsidiaries, all
necessary or appropriate waivers, consents and approvals and SEC "no-action"
letters to effect all necessary registrations, filings and submissions and to
lift any injunction or other legal bar to the Merger (and, in such case, to
proceed with the Merger as expeditiously as possible).

          (b)  Without limitation of the foregoing, each of USA Waste and AWS
undertakes and agrees to file as soon as practicable, and in any event prior to
30 days after the date hereof, a Notification and Report Form under the HSR Act
with the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division").  Each of USA Waste and AWS
shall (i) respond as promptly as practicable to any inquiries received from the
FTC or the Antitrust Division for additional information or documentation and to
all inquiries and requests received from any State Attorney General or other
governmental authority in connection with antitrust matters and (ii) not extend
any waiting period under the HSR Act or enter into any agreement with the FTC or
the Antitrust Division not to consummate the transactions contemplated by this
Agreement, except with the prior written consent of the other parties hereto.

          (c)  In the event any litigation is commenced by any person or entity
relating to the transactions contemplated by this Agreement, including an
Acquisition Transaction, USA Waste shall have the right, at its own expense, to
participate therein, and AWS will not settle any such litigation without the
consent of USA Waste, which consent will not be unreasonably withheld.

     Section 8.6 Public Statements. The parties shall consult with each other
prior to issuing any press release or any written public statement with respect
to this Agreement or the transactions contemplated hereby and shall not issue
any such press release or written public statement prior to such consultation.

     Section 8.7   Option Plans.

          (a)  Prior to the Effective Time, AWS shall use its reasonable best
efforts to redeem all unexpired and unexercised "in the money" stock options for
an amount of cash equal to at least the difference between the exercise price of
such stock options and the Merger Consideration (with no adjustment to reflect
the Distribution).  Furthermore, prior to the Effective Time, AWS shall use its
reasonable best efforts to redeem all other unexpired and unexercised stock
options.  Each such option to purchase AWS Common Stock is referred to herein as
an "AWS Option."

          (b)  With respect only to any AWS Options that would be held by Avalon
Employees (as defined in the Distribution Agreement) after the Effective Time
("Avalon Employee Options"), to the extent that any such Avalon Employee Options
have not been redeemed in accordance with Section 8.7(a) prior to the Effective
Time, AWS and USA Waste shall take such action as may be legally permissible to
cause each such Avalon Employee Option to be automatically converted at the
Effective Time into an option (each, an "Avalon Option") to purchase shares of
Avalon common stock.  From the Effective Time, all references in the stock
option agreements for such Avalon Employee Options to AWS shall be deemed to
refer to Avalon.  Avalon shall assume all of AWS's obligations with respect to
such Avalon Employee Options as so amended and shall, from and after the
Effective Time, make available for issuance upon exercise of any Avalon Options
the shares of Avalon common stock covered thereby and shall file a registration
statement on Form S-8 to cover the shares of Avalon common stock subject to
those Avalon Options.

          (c)  At the Effective Time, each Retained Stock Option (as defined
under Section 3.6), whether or not then exercisable, shall be automatically
converted by virtue of the Merger into an option to purchase shares of USA Waste
common stock.

          (d)  AWS hereby represents to USA Waste that the terms of its stock
option plans governing the AWS Options permit the transactions contemplated by
this Section 8.7.

     Section 8.8 Notification of Certain Matters. Each of AWS, USA Waste and
Mergerco agrees to give prompt notice to each other of, and to use commercially
reasonable efforts to remedy, (i) the occurrence or failure to occur of any
event which occurrence or failure to occur would be likely to cause any of its
representations or warranties in this Agreement to be untrue or inaccurate in
any material respect at the Effective Time and (ii) any material failure on its
part to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; provided, however, that the delivery
of any notice pursuant to this

                                      B-31
<PAGE>
 
Section 8.8 shall not limit or otherwise affect the remedies available hereunder
to the party receiving such notice.

     Section 8.9   Directors' and Officers' Indemnification.

          (a)  The indemnification provisions of the Articles of Incorporation
of the Surviving Corporation as in effect at the Effective Time shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who at the Effective Time were directors, officers, employees or
agents of AWS, unless such modification is required by law.

          (b)  Without limiting Section 8.9(a), after the Effective Time, each
of USA Waste and the Surviving Corporation shall, to the fullest extent
permitted under applicable law, indemnify and hold harmless each present and
former director, officer, employee and agent of AWS or any of its subsidiaries
(each, together with such person's heirs, executors or administrators, an
"Indemnified Party" and collectively, the "Indemnified Parties") against any
costs or expenses (including attorneys' fees), judgments, fines, losses, claims,
damages, liabilities and amounts paid in settlement in connection with any
actual or threatened claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of, relating to,
or in connection with any action or omission occurring or alleged to occur prior
to the Effective Time (including, without limitation, acts or omissions in
connection with any such person serving as an officer, director or other
fiduciary in any entity if such service was at the request or for the benefit of
AWS) or arising out of or pertaining to the transactions contemplated by this
Agreement or the Distribution Agreement.  In the event of any such actual or
threatened claim, action, suit, proceeding or investigation (whether arising
before or after the Effective Time), (i) AWS or USA Waste and the Surviving
Corporation, as the case may be, shall pay the reasonable fees and expenses of
counsel selected by the Indemnified Parties, which counsel shall be reasonably
satisfactory to USA Waste and the Surviving Corporation, promptly after
statements therefor are received and shall pay all other reasonable expenses in
advance of the final disposition of such claim, action, suit, proceeding or
investigation, (ii) USA Waste and the Surviving Corporation will cooperate and
use all reasonable efforts to assist in the vigorous defense of any such matter,
and (iii) to the extent any determination is required to be made with respect to
whether an Indemnified Party's conduct complies with the standards set forth
under the OGCL and USA Waste's or the Surviving Corporation's respective
charters or by-laws, such determination shall be made by independent legal
counsel acceptable to USA Waste or the Surviving Corporation, as the case may
be, and the applicable Indemnified Party; provided, however, that neither USA
Waste nor the Surviving Corporation shall be liable for any settlement effected
without its written consent (which consent shall not be unreasonably withheld);
and, provided, further, that if USA Waste or the Surviving Corporation advances
or pays any amount to any person under this paragraph (b) and if it shall
thereafter be finally determined by a court of competent jurisdiction that such
person was not entitled to be indemnified hereunder for all or any portion of
such amount, to the extent required by law, such person shall repay such amount
or such portion thereof, as the case may be, to USA Waste or the Surviving
Corporation, as the case may be.  The Indemnified Parties as a group may not
retain

                                      B-32
<PAGE>
 
more than one law firm to represent them with respect to each matter unless
there is, under applicable standards of professional conduct, a conflict on any
significant issue between the positions of any two or more Indemnified Parties.

          (c)  In the event the Surviving Corporation or USA Waste or any of
their successors or assigns (i) consolidates with or merges into any other
person and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provisions shall be made so that the successors and assigns of the Surviving
Corporation or USA Waste shall assume the obligations set forth in this Section
8.9.

          (d)  USA Waste and the Surviving Corporation shall not cancel or
terminate any policies of directors' and officers' liability insurance covering
Indemnified Parties that does not extend coverage for more than one year after
the Effective Time.

          (e)  USA Waste shall pay all reasonable expenses, including reasonable
attorneys' fees, that may be incurred by any Indemnified Party in enforcing the
indemnity and other obligations provided in this Section 8.9.  The rights of
each Indemnified Party hereunder shall be in addition to, and not in limitation
of, any other rights such Indemnified Party may have.  The provisions of this
Section 8.9 shall survive the consummation of the Merger and expressly are
intended to benefit the Indemnified Parties.

     Section 8.10 Corrections to the Proxy Statement. Prior to the date of
approval of the Merger by AWS's stockholders, USA Waste or AWS shall correct
promptly any information provided by it to be used specifically in the Proxy
Statement that shall have become false or misleading in any material respect,
and AWS shall take all steps necessary to file with the SEC any amendment or
supplement to the Proxy Statement so as to correct the same and to cause the
Proxy Statement as so corrected to be disseminated to the stockholders of AWS,
in each case to the extent required by applicable law.

     Section 8.11 Credit Facility. Immediately after the Effective Time, USA
Waste shall cause the Surviving Corporation to pay any amounts still outstanding
under the Credit Facility after the payment made by AWS pursuant to Section 3.6.
USA Waste shall, and shall cause the Surviving Corporation to, use commercially
reasonable efforts to have the lender or lenders under the Credit Facility
release and terminate any guarantees or indemnities provided by any Contributed
Subsidiaries (as defined in the Distribution Agreement) with respect to the
Credit Facility promptly after such payment.

     Section 8.12 Board Approval of Distribution. The Board of Directors of AWS
will approve the Contribution and the declaration of the Distribution as
promptly as practicable (but no later than twenty (20) days) after delivery of
the Valuation to AWS unless the Board of Directors of AWS reasonably determines
that the Contribution or the Distribution violates Section 1701.33 of the OGCL.
A breach of this covenant shall constitute a willful and intentional breach of
this Agreement.

                       TERMINATION, AMENDMENT AND WAIVER

     Section 10.1 Termination. This Agreement may be terminated at any time
prior to the Closing Date, whether before or after approval and adoption by the
stockholders of AWS as follows:

          (a)  AWS shall have the right to terminate this Agreement:

               (i)  if any of the representations and warranties of USA Waste or
     Mergerco shall fail to be true and correct and such failure will cause the
     conditions set forth in Section 9.2(a) to be incapable of being satisfied
     by July 31, 1998 (the "Termination Date") and such failure has not been
     cured in all material respects within 30 days after notice of such breach
     is given to USA Waste by AWS;

               (ii)  if the Merger is not completed by the Termination Date;
     provided, that the right to terminate this Agreement pursuant to this
     Section 10.1(a)(ii) shall not be available to AWS (A) if the failure of AWS
     to fulfill any obligation to USA Waste under or in connection with this
     Agreement has been the cause of or resulted in the failure of the Merger to
     occur on or before such date or (B) if AWS is at such time exercising its
     rights under Section 7.3(b);

               (iii)   if the Merger is enjoined by a final, unappealable court
     order;

               (iv)  if the requisite votes of the stockholders of AWS shall not
     have been obtained at the AWS Stockholders' Meeting;

               (v)  if USA Waste (A) fails to perform in any material respect
     any of its material covenants in this Agreement and (B) does not cure such
     default in all material respects within 30 days after notice of such
     default is given to USA Waste by AWS;

               (vi)  if (A) AWS receives a Superior Proposal from any third
     party (excluding any affiliate of AWS or any group of which any affiliate
     of AWS is a member), (B) AWS's Board of Directors resolves to accept such
     Superior Proposal, and (C) AWS shall have given USA Waste two days' prior
     written notice of its intention to terminate this Agreement pursuant to
     this provision; provided, that such termination shall not be effective
     until such time as the payment required by Section 8.4(b) shall have been
     received by USA Waste;

     party (excluding any affiliate of AWS or any group of which any affiliate
     of AWS is a member) for all outstanding shares of AWS Common Stock, (B)
     AWS's Board of Directors determines in good faith that such offer
     constitutes a Superior Proposal and resolves to accept such Superior
     Proposal or recommend to the stockholders that they tender their shares in
     such tender or exchange offer, and (C) AWS shall have given USA Waste two
     days' prior written notice of its intention to terminate this Agreement
     pursuant to this provision; provided, that such termination shall not be
     effective until such time as the payment required by Section 8.4(b) shall
     have been received by USA Waste; or

               (viii)   if any of the Ancillary Agreements have been terminated
     in accordance with their respective terms.

          (b)  USA Waste shall have the right to terminate this Agreement;

               (i)  if any of the representations and warranties of AWS shall
     fail to be true and correct and such failure will cause the conditions set
     forth in Section 9.3(a) to be incapable of being satisfied by the
     Termination Date and such failure has not been cured in all material
     respects within 30 days after notice of such breach is given to AWS by USA
     Waste;

               (ii)  if the Merger is not completed by the Termination Date;
     provided, that the right to terminate this Agreement pursuant to this
     Section 10.1(b)(ii) shall not be available to USA Waste if the failure of
     USA Waste or Mergerco to fulfill any obligation to AWS under or in
     connection with this Agreement has been the cause of or resulted in the
     failure of the Merger to occur on or before such date;

               (iii)   if AWS (A) fails to perform in any material respect any
     of its material covenants in this Agreement and (B) does not cure such
     default in all material respects within 30 days after written notice of
     such default is given to AWS by USA Waste;

               (iv)  if the Board of Directors of AWS shall have resolved to
     accept a Superior Proposal or shall have recommended to the stockholders of
     AWS that they tender their shares in a tender or exchange offer commenced
     by a third party (excluding any affiliate of USA Waste or any group of
     which any affiliate of USA Waste is a member);

               (v)  if the requisite votes of the stockholders of AWS shall not

     order; or

<PAGE>
 
               (vii)   if any of the Ancillary Agreements have been terminated

Agreement by either USA Waste or AWS pursuant to the provisions of Section 10.1,
this Agreement shall forthwith become void and there shall be no further
obligations on the part of AWS, USA Waste, Mergerco or their respective officers
or directors (except for the obligations set forth in this Section 10.2 and in
the second sentence in Section 8.1(a) and in Sections 8.1(b), 8.4 and 11.4 and
the Confidentiality Agreement, all of which shall survive the termination).
Nothing in this Section 10.2 shall relieve any party from liability for any
willful or intentional breach of this Agreement.

     Section 10.3 Amendment. This Agreement may not be amended except by action
taken by the parties' respective Boards of Directors or duly authorized
committees thereof and then only by an instrument in writing signed on behalf of
each of the parties hereto and in compliance with applicable law.

hereto may (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered

conditions herein. Any agreement on the part of a party hereto to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.

                               GENERAL PROVISIONS

     Section 11.1 Non-Survival of Representations and Warranties. The
representations and warranties in this Agreement or in any document delivered
pursuant hereto shall not survive the Merger and, after the effectiveness of the
Merger, neither AWS, USA Waste, Mergerco, Avalon nor their respective officers

agreements and covenants in this Agreement that survive the consummation of the
Merger in accordance with their terms shall so survive.

                    CONTRIBUTION AND DISTRIBUTION AGREEMENT


     CONTRIBUTION AND DISTRIBUTION AGREEMENT, dated as of May 7, 1998 (the
"Agreement"), by and between American Waste Services, Inc., an Ohio corporation
("AWS") and Avalon Holdings Corporation, an Ohio corporation and a wholly owned
subsidiary of AWS ("Avalon").

                              W I T N E S S E T H:
                              ------------------- 

     WHEREAS, AWS through its subsidiaries owns and operates nonhazardous solid
waste landfills; transports hazardous and nonhazardous waste; provides
transportation and disposal brokerage and management services; provides refuse
collection services; provides environmental engineering, site assessment,
analytical laboratory and remediation services; is a common carrier of general
and bulk commodities; and operates a golf course through its subsidiaries
(collectively, the "Businesses"); and

     WHEREAS, AWS, USA Waste Services, Inc., a Delaware corporation ("USA
Waste"), and C&S Ohio Corp., an Ohio corporation and a wholly owned subsidiary
of USA Waste ("Mergerco"), are parties to an Agreement and Plan of Merger, dated
as of February 6, 1998 (the "Merger Agreement"), providing for, among other
things, the merger of Mergerco with and into AWS (the "Merger"), pursuant to
which AWS will become a wholly owned subsidiary of USA Waste; and

     WHEREAS, AWS and USA Waste have agreed that, at the Effective Time (as
defined in the Merger Agreement), the only Businesses that AWS will have will be
the non-hazardous solid waste landfills it owns and operates, the refuse
collection services it provides and its landfill gas collection and sales
business (the "Retained Businesses"); and

     WHEREAS, AWS has agreed with USA Waste to dispose of all of its other
Businesses (the "Contributed Businesses") and all of its other assets,
properties and rights that USA Waste does not need in order to operate the
Retained Businesses (the "Nonessential Assets") prior to the Effective Time; and

     WHEREAS, the Board of Directors of AWS has determined that it is in the
best interests of AWS's shareholders that AWS contribute (as defined below) all
of the assets, properties and rights of the Contributed Businesses and all the
Nonessential Assets (collectively, the "Contributed Assets") to Avalon and that
Avalon assume the Assumed Liabilities (as defined below); and

     WHEREAS, it is a condition precedent to the consummation of the Merger, and
the Board of Directors of AWS has determined that it is in the best interests of
AWS's shareholders, that following the contribution of the Contributed Assets to
and the assumption of the Assumed

                                      C-1
<PAGE>
 
Liabilities by Avalon, AWS distribute all of the shares of capital stock of
Avalon to AWS's shareholders prior to the Effective Time (the "Distribution");
and

     WHEREAS, it is also contemplated in the Merger Agreement that, on or before
the Distribution, AWS will cause all of its subsidiaries that it will continue
to own after the Distribution to pay certain obligations of those entities to
Avalon as set forth herein; and

     WHEREAS, AWS and Avalon desire to more fully describe the Contributed
Assets, the Assumed Liabilities, the obligations of AWS and its subsidiaries to
Avalon and its subsidiaries, and the obligations of Avalon and its subsidiaries
to AWS and its subsidiaries after the Distribution.

     NOW, THEREFORE, in consideration of the agreements and covenants contained
herein and in the other agreements and instruments executed in connection with
this Agreement and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

                          I.  CONTRIBUTION; ASSUMPTION

     1.1   Contribution of Assets.
           ----------------------
          (a)  Upon the terms and subject to the conditions of this Agreement,
on or before the Distribution Date (as defined below), AWS shall convey, assign,
transfer and deliver (collectively, "contribute") to Avalon as a contribution to
capital, all of the right, title and interest of AWS in and to all of the
Contributed Assets, wherever such assets are located and whether real, personal
or mixed and whether tangible or intangible.  Without limiting the generality of
the foregoing, the Contributed Assets shall include the following:

               (i)  all assets, properties and rights owned by AWS listed on
     Schedule 1.1A hereto; and

               (ii)  all outstanding shares of capital stock and other
     securities (as defined in the Securities Exchange Act of 1934, as amended
     (the "Exchange Act")) of the subsidiaries of AWS listed on Schedule 1.1 B
     hereto (the "Contributed Subsidiaries").

          (b)  If AWS disposes of any Contributed Asset prior to the
Distribution Date, AWS shall have no obligation to purchase or otherwise acquire
any substitute or replacement asset, property or right.

          (c)  No contract, agreement, permit or franchise which is not
assignable by its terms or by law without the consent of any party thereto other
than AWS or any of its subsidiaries shall be deemed assigned pursuant to this
Agreement unless and until such consent or a waiver therefrom is given. AWS
shall use commercially reasonable efforts (not involving the payment of
consideration) to obtain prior to the Distribution Date all such consents,
waivers and assignments.  If any such consent, waiver or assignment is not
obtained prior to the

                                      C-2
<PAGE>
 
Distribution Date and the Distribution is nevertheless consummated, AWS shall
continue to use commercially reasonable efforts to obtain all such consents,
waivers or assignments as have not been obtained prior to such date. In order to
provide Avalon with the full value and benefit of every contract, agreement,
permit and franchise that has not been assigned as provided in this Section 1.1
(c), AWS shall cooperate with Avalon after the Distribution Date in any
reasonable arrangement (such as subcontracting, sublicensing or subleasing)
designed to provide to Avalon and its subsidiaries, on terms at least as
favorable as those to which AWS and its subsidiaries are entitled, the full
value and benefit, as well as the obligations and liabilities, under the
applicable contract, agreement, permit or franchise, including, without
limitation, enforcement, at the cost and for the benefit of Avalon and its
subsidiaries, of any and all rights of AWS and its subsidiaries against any
other party thereto arising out of the breach or cancellation thereof by such
party. Avalon and AWS, as applicable, shall maintain insurance in an amount
sufficient to comply with any insurance requirements of such contracts.

     1.2  The Retained Assets. AWS shall retain and the Contributed Assets shall
          -------------------
not include the following;

          (a)  the assets, properties and rights owned by AWS listed on Schedule
1.2 A hereto (the "Retained Assets"); and

          (b)  all outstanding shares of capital stock and other securities of
the subsidiaries of AWS listed on Schedule 1.2 B hereto (the "Retained
Subsidiaries").

     1.3   Assumption of Liabilities.
           ------------------------- 

          (a)  Upon the terms and subject to the conditions of this Agreement,
on the Distribution Date, Avalon shall, pursuant to an agreement of assumption
in form and substance reasonably satisfactory to USA Waste and Avalon (the
"Assumption Agreement"), assume and agree to perform, pay, satisfy or discharge,
when due, to the extent not theretofore performed, paid, satisfied or
discharged, (i) the Liabilities (as defined below) of AWS arising out of or
related to the Contributed Assets, (ii) the Liabilities of AWS, if any, arising
out of or related to the action entitled "Werbowski vs. American Waste Services,
Inc., et al.," (iii) contractual obligations related to sponsorship of the LPGA
Golf Tournament at Avalon Lakes Golf Course, and (iv) other Liabilities
specified herein as being assumed by Avalon (for example, in Section 2.1(i))
(collectively, the "Assumed Liabilities").

          (b)  Notwithstanding anything to the contrary set forth herein, (i)
any Liability of Avalon and its subsidiaries for any taxes incurred or accrued
prior to the Distribution Date shall be governed solely by the express terms of
the Tax Allocation Agreement, dated as of the date hereof (the "Tax Allocation
Agreement"), by and among USA Waste, AWS and Avalon, and (ii) any Liability of
Avalon and its subsidiaries from and after the Distribution Date with respect to
any employees of AWS and its subsidiaries shall be governed solely by the
express provisions of Article II hereof.

                                      C-3
<PAGE>
 
          (c)  AWS and Avalon shall each use commercially reasonable efforts, on
or prior to the Distribution Date, to have (i) AWS or any Retained Subsidiary
removed as a guarantor of or obligor for any Assumed Liability and (ii) to
substitute Avalon or a Contributed Subsidiary as such guarantor or obligor
thereof.  If any such removal and substitution is not obtained prior to the
Distribution Date and the Distribution is nevertheless consummated, Avalon shall
continue to use commercially reasonable efforts to obtain all such removals and
substitutions.

          (d)  With respect to any action, suit, arbitration, inquiry,
proceeding or investigation by or before any court, governmental regulatory or
administrative agency or commission or arbitration tribunal (any "Action") now
pending or commenced prior to, on or after the Distribution Date to the extent
that such Action arises out of or relates solely to any Contributed Assets or
Terminated Employee or Avalon Employee (both as defined below), AWS and Avalon
shall use commercially reasonable efforts to have AWS or the applicable Retained
Subsidiary removed as a party to such Action following the Distribution Date.

          (e)  For purposes of this Agreement, "Liabilities" shall mean all
debts, obligations, liabilities and commitments of any nature, whether absolute
or contingent, monetary or non-monetary, direct or indirect, known or unknown,
matured or unmatured.

     1.4 Retained Liabilities.  Except for the Assumed Liabilities, Avalon does
         --------------------
not hereby, and shall not, assume or in any way undertake to pay, perform,
satisfy or discharge any other Liability of AWS or any Retained Subsidiary and
AWS or the applicable Retained Subsidiary shall perform, pay, satisfy and
discharge all such Liabilities other than the Assumed Liabilities (collectively,
the "Retained Liabilities").

     1.5  Issuance of Shares.  In exchange for the contribution of the
          ------------------
Contributed Assets and the assumption of the Assumed Liabilities, on or before
the Distribution Date, Avalon shall issue to AWS 25,301308 shares of its Class A
Common Stock, par value $.01 ("Avalon Class A Stock"), and 5,123,858 shares of
its Class B Common Stock, par value $.01 ("Avalon Class B Stock," which,
together with the Avalon Class A Stock, is sometimes collectively referred to
herein as the "Avalon Common Stock"). Those shares of Avalon Class A Stock and
Avalon Class B Stock shall initially be represented by one stock certificate
each. All shares of Avalon capital stock to be issued pursuant to this Section
1.5 shall be validly issued, fully paid and nonassessable.

     1.6   Passage of Title.  Title to all Contributed Assets shall pass from
           ----------------
AWS to Avalon at the Closing (as defined below). If any Contributed Asset is
lost or damaged due to some casualty or accident prior to the Distribution Date,
on the Distribution Date, AWS shall, as part of the Contributed Assets, assign
to Avalon all rights of action, including insurance claims, with respect to such
Contributed Asset. This constitutes AWS's sole obligation with respect to such
lost or damaged Contributed Asset.

     1.7   Unemployment Compensation and Workers Compensation Insurance Ratings.
           -------------------------------------------------------------------- 
Following the Closing, AWS and the Retained Subsidiaries shall, if requested by
Avalon and at

                                      C-4
<PAGE>
 
Avalon's expense, take all steps commercially reasonably necessary or permitted
to allow Avalon and/or the Contributed Subsidiaries to be assigned the
experience rating of AWS and/or the Retained Subsidiaries with respect to
workers compensation insurance and/or unemployment compensation insurance.

     1.8   Valuation.  The aggregate value of Avalon after the contribution of
           ---------
the Contributed Assets and the assumption of the Assumed Liabilities shall be
determined by Houlihan, Lokey, Howard & Zukin, Inc. ("HLHZ") which has been
retained for that purpose. On or before the Distribution Date, AWS shall cause
HLHZ to deliver to Avalon and USA Waste its final report (the "HLHZ Report")
setting forth such valuation. AWS, USA Waste and Avalon shall report the
federal, state and local income and other tax consequences of the Distribution
(including reporting requirements on Form 1099) contemplated hereby in a manner
consistent with such determination and shall not take any position inconsistent
therewith upon examination of any tax return, in any refund claim or in any
Action.

                   II.  EMPLOYEES AND EMPLOYEE BENEFIT PLANS

     2.1   Employment.
           ---------- 

          (a)  No later than 15 days after execution of this Agreement, Avalon
shall deliver to USA Waste a list of all employees of AWS and the Retained
Subsidiaries to whom Avalon wishes to extend offers of employment which are
conditioned upon the occurrence of the Closing (the "Employee List").

          (b)  Within 30 days of receipt of the Employee List, USA Waste shall
deliver to Avalon a list of the individuals disclosed on the Employee List whom
USA Waste wishes to retain as employees of AWS or the Retained Subsidiaries, as
applicable (the "Overlap Employees").

          (c)  Avalon shall be free to negotiate terms of employment with
persons on the Employee List who are not Overlap Employees and each of Avalon
and USA Waste shall be free to make offers to and negotiate with Overlap
Employees, it being understood and agreed that the final decision as to which
offer to accept shall rest with the individual person.

          (d)  As soon as practicable, but in no event later than 30 days prior
to the scheduled date of the meeting of stockholders of AWS to consider the
Merger, USA Waste shall deliver to AWS and Avalon a list of all employees of AWS
and the Retained Subsidiaries (i) whose employment USA Waste will cause AWS or
the applicable Retained Subsidiary to terminate within two business days after
the Closing Date or (ii) whom USA Waste will cause AWS or the applicable
Retained Subsidiary to terminate within 60 days after the Closing Date (each
such person described in (i) and (ii) above is hereinafter referred to as a
"Terminated Employee.")

                                      C-5
<PAGE>
 
          (e)  Every employee of any Contributed Subsidiary and each individual
who accepts employment with Avalon is hereinafter referred to as an "Avalon
Employee."

          (f)  Every employee of AWS and the Retained Subsidiaries who is not an
Avalon Employee or a Terminated Employee is hereinafter referred to as a
"Retained Employee."

          (g)  Any person who would be both a Terminated Employee and an Avalon
Employee under the above definitions shall be treated solely as an Avalon
Employee and not as a Terminated Employee for purposes of this Agreement.

          (h)  Avalon or any Contributed Subsidiary may, but shall not be
obligated to, offer employment to any Terminated Employee.

          (i)  From and after the Closing Date, Avalon shall assume and shall
pay, satisfy and discharge any Liability (i) arising out of workers'
compensation claims by Avalon Employees and Terminated Employees unless the
claim relates to a Terminated Employee and is based solely on an occurrence
after the Closing Date (as defined in the Merger Agreement); or (ii) arising out
of or related to the termination of employment of any Avalon Employee or
Terminated Employee; provided, however, that Avalon shall not assume and shall
not pay, satisfy and discharge any Liability arising out of or related to the
termination of employment of any Terminated Employee who immediately prior to
the Distribution Date was an employee of American Landfill, Inc., American
Landfill Gas Company, East Liverpool Landfill, Inc., Mahoning Landfill, Inc. or
SLF Development, Inc., to the extent that such Liability arises out of any
allegation that such termination was in violation of applicable law (as opposed
to being in breach of any agreement).  From and after the Closing Date, AWS and
the Retained Subsidiaries shall pay, satisfy and discharge any Liability arising
out of or related to the employment relations between any of them and any
Retained Employee or any former employee of any Retained Subsidiary or AWS who
is not a Terminated Employee and not an Avalon Employee.

          (j)  From and after the Closing Date, Avalon and the Contributed
Subsidiaries shall pay, satisfy and discharge any Liability arising out of or
relating to the employment relations between each of them and their respective
employees.

     4.1   Cooperation Prior to the Distribution.   Commencing as promptly as
           -------------------------------------
practicable after the date hereof and until the Distribution Date, subject to
the provisions of Article VI hereof, AWS and Avalon shall take all such actions
as may be necessary or appropriate to effect the Distribution, including,
without limitation, the specific actions set forth in Sections 4.2 and 4.3.

     4.2   Securities Filings.
           ------------------

Securities and Exchange Commission (the "SEC") a registration statement on Form
10 (the "Form 10") to effect the registration of the Avalon Class A Stock
pursuant to the Exchange Act.  AWS and Avalon shall use commercially reasonable

promptly as practicable.  If AWS reasonably determines that the Distribution may
not be effected without registering the shares of Avalon Class A Stock  to be
distributed pursuant to the Securities Act of 1933, as amended (the "Securities
Act"), AWS and Avalon shall prepare and Avalon shall file with the SEC a
registration statement on Form S-1 (the "Form S-1") to effect such registration

reasonable efforts to cause the Form S-1 to be declared effective under the

appropriate procedures in connection with the

                                      C-8
<PAGE>

time as (i) the Form 10 and the Form S-1, if necessary, shall have been declared
effective by the SEC and (ii) the Closing shall have occurred.

record on the Distribution Record Date of shares of Class A Common Stock, no par
value ("AWS Class A Stock"), of AWS one share of Avalon Class A Stock for every

no fractional shares of Avalon Common Stock shall be distributed in the

fractional share.

          (e)  Notwithstanding any provision of this Agreement to the contrary,
none of AWS, Avalon, USA Waste nor the Distribution Agent shall be liable to any
person for any amount or any shares of Avalon capital stock delivered to a
public official upon his or her request pursuant to applicable abandoned
property, escheat or similar laws.

                                 V.  COVENANTS

     5.1   AWS Approval of Certain Avalon Actions.  AWS shall cooperate with
           --------------------------------------

Contributed Businesses, respectively, following the Contribution and the
Distribution; provided that any associated costs and expenses shall be borne by
the party that is the beneficiary of such license or permit.

     5.3   Acts and Instruments.
           --------------------

          (a)  Whenever reasonably requested to do so by the other party after
the Distribution Date, AWS and Avalon, respectively, shall do, execute,
acknowledge and deliver all such acts, bills of sale, assignments,
confirmations, consents and other instruments and documents, in form reasonably
satisfactory to such other party, as shall be necessary or advisable to carry
out the intent of this Agreement and to (i) vest in Avalon all the right, title
and interest of AWS in and to the Contributed Assets and (ii) effectuate the
assumption of the Assumed Liabilities by Avalon.  AWS and Avalon shall take such
steps as may be required to put Avalon and AWS, respectively, in actual
possession and control of the Contributed Assets and the Retained Assets,
respectively, as of the time of Closing.

          (b)  Without limiting in any respect the right, title and interest in
and to the Contributed Assets to be acquired by Avalon hereunder, effective upon
the Closing, AWS hereby irrevocably authorizes Avalon and its successors and
assigns: to demand and receive, from time to time, any and all of the
Contributed Assets, to give receipts and releases for or in respect of the same,
to collect, assert or enforce any claim, right or title of any kind therein or
thereto and, for such purpose, from time to time, to institute and prosecute in
the name of AWS, or otherwise, any and all proceedings at law, in equity or
otherwise, which Avalon shall deem expedient or desirable.  Likewise, Avalon
hereby irrevocably authorizes AWS and its successors and assigns to take all
actions reasonably necessary to effectuate the assumption of the Assumed
Liabilities by Avalon.  Avalon shall retain for its own account any amounts
collected pursuant to the foregoing authorization, and AWS shall pay to Avalon,
if and when received (but subject to Section 5.6), any amounts that shall be
received by AWS after the Distribution Date in respect of any of the Contributed
Assets.  Avalon shall pay to AWS, if and when received (but subject to Section
5.6), any amounts that shall be received by Avalon after the Distribution Date
in respect of the Retained Businesses.

     5.4   Correspondence.  AWS hereby authorizes Avalon, on and after the
           --------------
Distribution Date, to receive and open mail addressed to AWS and to deal with
the contents thereof in a responsible manner; provided, that such mail relates
(or reasonably appears to relate) to the Contributed Businesses, the Contributed
Assets or the Assumed Liabilities. Avalon shall promptly deliver to AWS any mail
that relates (or reasonably appears to relate) to the Retained Businesses or the
Retained Liabilities addressed to AWS which is delivered to and received by it.
Avalon hereby authorizes AWS, on and after the Distribution Date, to receive and
open mail addressed to Avalon and to deal with the contents thereof in a
responsible manner; provided, that such mail relates (or reasonably appears to
relate) to the Retained Businesses or the Retained

                                      C-10
<PAGE>
 
Liabilities. AWS shall promptly deliver to Avalon any mail that relates (or
reasonably appears to relate) to the Contributed Businesses, the Contributed
Assets or the Assumed Liabilities addressed to Avalon which is delivered to and
received by it.

     5.5   Further Assistance.  In addition to the actions specifically
           ------------------
provided for elsewhere in this Agreement, each of the parties hereto shall use
commercially reasonable efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, all things, reasonably necessary, proper or
advisable under applicable laws, regulations and agreements to consummate and
make effective the transactions contemplated by this Agreement, including,
without limitation, using commercially reasonable efforts to obtain the consents
and approvals to enter into any amendatory agreements and to make the filings
and applications necessary or desirable to have been obtained, entered into or
made in order to consummate the transactions contemplated by this Agreement.

     5.6   Settlement for Cash Collections and Disbursements.  For each
           -------------------------------------------------
calendar month, commencing with the month in which the Closing occurs and
continuing until determined by the parties no longer to be necessary, Avalon and
AWS shall cause all cash collections and cash disbursements received by Avalon
and its subsidiaries for the benefit of AWS and its subsidiaries, or by AWS and
its subsidiaries for the benefit of Avalon and its subsidiaries, during the
relevant month to be remitted to the party entitled to the benefit thereof as
promptly as reasonably possible after the receipt thereof.

     5.7   Insurance.  On or before the Distribution Date, AWS shall transfer
           ---------
and assign to Avalon all of AWS's insurance policies, other than the directors'
and officers' indemnification insurance. If any such policy by its terms may not
be assigned, it is the intent of the parties that Avalon receive the benefit of
any coverage under any insurance policy. AWS, at Avalon's expense, shall keep
such policy in effect during the remaining term of the policy and refrain from
taking any actions (other than making a claim) which may affect Avalon's
entitlement to the benefits of, or coverage under, such policy. With respect to
any such policies, AWS shall seek to have Avalon and its subsidiaries named as
insureds with respect to occurrences prior to the Distribution Date, at Avalon's
expense, if requested to do so by Avalon. Notwithstanding the foregoing, AWS
shall receive, to the extent such benefits may be available, the benefit of all
insurance policies of AWS existing prior to the Closing to the extent such
insurance covers Retained Liabilities, and the parties will enter into
commercially reasonable arrangements to effect the provisions of this sentence.

     5.8   Covenant Not to Compete.
           ----------------------- 

          (a)  During the period of time that begins on the Closing Date (as
defined in the Merger Agreement) and ends on the third anniversary thereof (the
"Covenant Period"), Avalon agrees that it will not, directly or indirectly,

               (i)  carry on or be engaged in (whether for its own account or
     for the account of any other person, other than AWS or USA Waste), the
     collection of refuse or

                                      C-11
<PAGE>
 
     garbage, or the disposal of non-hazardous solid waste, from any source
     located within a 100-mile radius of American Landfill, Mahoning Landfill or
     East Liverpool Landfill; or

               (ii)  share in the earnings of, beneficially own or hold any
     security issued by, or otherwise own or hold any interest in, any person
     who or which owns or operates a landfill within a 100-mile radius American
     Landfill, Mahoning Landfill, or East Liverpool Landfill.

          (b)  Without limiting the generality of the provisions of this Section
5.8, Avalon shall be deemed to be engaged in a particular business if it
(whether alone or in association with one or more other persons) is an owner,
partner, stockholder, independent contractor or joint venturer of, or a lender
to, or an investor in, any person who or which is directly engaged in any such
business.

          (c)  Notwithstanding the foregoing provisions of this Section 5.8, (i)
Avalon may own, directly or indirectly, solely as an investment, securities if
Avalon is not an affiliate of the issuer of such securities and does not,
directly or indirectly, beneficially own more than 5% of the class of which such
securities are a part, (ii) Avalon may, directly or indirectly, engage in the
provision of technical and engineering services, transportation, and equipment
sales and leasing, (iii) Avalon may, directly or indirectly, engage in the
management or operation of captive landfills, such as the management of the
landfill in Ashtabula, Ohio, and (iv) Avalon may, directly or indirectly, engage
in the disposal and brokerage of disposal of non-hazardous solid waste which is
generated within (or is deposited at a transfer station owned or operated by
Avalon or its subsidiaries within) such 100-mile radius, so long as Avalon shall
provide AWS or USA Waste the right to make a proposal for disposal of any such
waste and Avalon shall be obligated to accept such proposal if the disposal rate
quoted by AWS for such waste plus the bona fide costs to be incurred by Avalon
in transporting such waste to the applicable landfill of AWS is less than or
equal to the total of the lowest bona fide disposal rate quoted by a third party
for such waste plus the bona fide costs to be incurred by Avalon in transporting
such waste to the applicable landfill of such third party.  For purposes of this
Section 5.8, a captive landfill includes a landfill that was a captive landfill
on the date Avalon or its subsidiary commences management or operation thereof,
but that subsequently accepts waste from third parties so long as Avalon or its
subsidiary does not directly or indirectly solicit, sell or market disposal of
waste from any third party.

          (d)  Avalon acknowledges that if it violates or threatens to violate
any of the provisions of this Section 5.8, AWS and USA Waste may have no
adequate remedy at law.  In that event, AWS and USA Waste shall have the right,
in addition to any other rights that may be available to them, to obtain in any
court of competent jurisdiction injunctive relief (without the necessity of
posting bond) to restrain any violation or threatened violation by Avalon of any
provision of this Section 5.8 or to compel specific performance by Avalon of one
or more of its obligations under this Section 5.8.  The seeking or obtaining by
AWS or USA Waste of such injunctive relief shall not foreclose or in any way
limit the right of AWS or USA Waste to obtain a money judgment against Avalon
for any damage to AWS or USA Waste that may result from any breach by Avalon of
any provision of this Section 5.8.

                                      C-12
<PAGE>
 
          (e)  Avalon acknowledges that the covenants contained in this Section
5.8 are reasonable in geographical and temporal scope and in all other respects.
If any court determines that any of such covenants, or any part thereof, are
unenforceable, then (i) the remainder of such covenants shall not be affected by
such determination and (ii) those of such covenants that are determined to be
unenforceable because of the duration or scope thereof may be reformed by the
court to reduce their duration or scope so as to render the same enforceable
against Avalon.

     5.9   Access to Information.
           --------------------- 

          (a)  Each of AWS and Avalon shall use commercially reasonable efforts
to arrange, as soon as practicable following the Distribution Date, for the
delivery to the other party of the relevant portions of all corporate books and
records.  AWS shall retain in its possession all relevant portions of the
corporate books and records relating directly and primarily to the Retained
Businesses, Retained Employees or Retained Liabilities, including all active
agreements, files and government filings and licenses, and all AWS general
corporate books and records.  From and after the Distribution Date, all such
books, records and copies shall be the property of AWS.  Avalon shall retain in
its possession all relevant portions of all books and records of AWS relating
directly and primarily to the Contributed Businesses, Avalon Employees,
Terminated Employees, Contributed Assets and Assumed Liabilities, including all
active agreements, files and government filings and licenses.  From and after
the Distribution Date, all such books, records and copies referred to in the
preceding sentence shall be the property of Avalon.  Any material containing
incidental information relating to the Retained Businesses, but relating
primarily to the Contributed Businesses, shall be retained by Avalon.  Any
material containing incidental information relating to the Contributed
Businesses, but relating primarily to the Retained Businesses, shall be retained
by AWS.

          (b)  From and after the Distribution Date, each of AWS and Avalon
shall afford to the other and its authorized accountants, counsel and other
designated representatives reasonable access during normal business hours,
subject to appropriate restrictions for confidential information, to the
personnel, properties, books and records of such party and its subsidiaries
insofar as such access is reasonably required by the other party.  Each of AWS
and Avalon also shall afford each other the right to have access to any of their
respective employees who may be relevant in connection with the conduct of their
respective businesses, including without limitation with respect to financial
and accounting requirements, employee benefit plan and ERISA matters, tax
requirements (including with respect to the preparation of any tax returns), and
requirements of applicable securities laws.  Each of AWS and Avalon shall
preserve until the 10th anniversary of the Distribution Date all of the
foregoing records; provided, however, that such records may be destroyed by a
party if such party sends to the other party written notice of its intent to
destroy records, specifying with particularity the contents of the records to be
destroyed.  Such records may then be destroyed after the 30th day after such
notice is given unless the other party objects to the destruction, in which case
the party seeking to destroy the records shall deliver such records to the
objecting party, subject to appropriate restrictions for confidential
information by the other party, and the right (subject to appropriate
restrictions for confidential information) to make copies of books and records
of such party.

          (c)  At all times from and after the Distribution Date, AWS or Avalon,
as applicable, shall use commercially reasonable efforts to make available to
the other upon written request its and its subsidiaries' officers, directors,
employees and agents as witnesses, subject to appropriate restrictions for
confidential information, to the extent that such persons may reasonably be
required in connection with any Actions in which the requesting party may from
time to time be involved (without reimbursement for such persons' salaries).

          (d)  At all times from and after the Distribution Date, AWS or Avalon,
as applicable, shall use commercially reasonable efforts to make available to
the other upon written request, subject to appropriate restrictions for
confidential information, its and its subsidiaries' records, books, contracts,
instruments, computer data and other data which may reasonably be required in
connection with any Actions in which the requesting party may from time to time
be involved.

          (e)  AWS and its subsidiaries shall hold, and shall cause its
employees, agents, consultants and advisors to hold, in strict confidence, using
the same efforts it uses protecting its own confidential and proprietary
information, all confidential or proprietary information concerning the
Contributed Businesses in its possession (except to the extent that such
information (i) is in the public domain or becomes publicly known through no
wrongful act of AWS, USA Waste or any of their respective subsidiaries or any of
its employees, agents, consultants or advisors, (ii) is received from a party
who is under no confidentiality or secrecy obligation with respect thereto, or
(iii) is disclosed pursuant to governmental or judicial requirements).  Avalon
and its subsidiaries shall hold, and shall cause its employees, agents,
consultants and advisors to hold, in strict confidence, using the same efforts
it uses protecting its own confidential and proprietary information, all
confidential or proprietary information concerning the Retained Businesses in
its possession (except to the extent that such information (i) is in the public
domain or becomes publicly known through no wrongful act of Avalon or any of its
subsidiaries or any of its employees, agents, consultants or advisors, (ii) is
received from a party who is under no confidentiality or secrecy obligation with
respect thereto, or (iii) is disclosed pursuant to governmental or judicial
requirements).

          (f)  Each of AWS and Avalon shall provide the other party with such
cooperation and information, including, without limitation, all records, books,
contracts, instruments, computer data and other data, as may be reasonably
requested by the other in connection with the preparation or filing of any
government report or other government filing contemplated by this Agreement or
in conducting any other government proceeding relating to pre-Distribution
events.  Such cooperation and information shall include, without limitation,
promptly forwarding copies of appropriate notices and forms or other
communications received from or sent to any governmental authority to the
appropriate party.  Each party shall make its employees and facilities available
during normal business hours and on reasonable prior notice to provide
explanation of any documents or information provided hereunder.

     5.10   Certain Transaction Costs.  Avalon shall pay all taxes and other
            -------------------------
governmental assessments, charges or levies, costs of title insurance and other
conveyance costs which arise or are incurred in connection with the contribution
of the Contributed Assets to Avalon, including,

                                      C-14
<PAGE>
 
without limitation, all sales, value-added, registration, transfer (including
documentary and stamp) or similar taxes, whether domestic or foreign, but
excluding any taxes based upon AWS's income.

     5.11   Certain Agreements.  Set forth on Schedule 5.11 is a list of all
            ------------------
contracts and agreements (and outstanding bids and quotations, which if
accepted, would fall within this sentence) pursuant to which (i) one of the
Retained Subsidiaries or AWS is a party and under which one of the Contributed
Subsidiaries directly or indirectly (e.g., by rendering services or providing
products to a Retained Subsidiary or AWS which are then used by such Retained
Subsidiary or AWS to render services or provide products or disposal space to
the third party) renders services or provides products or disposal space to the
third party who is a party thereto or (ii) one of the Contributed Subsidiaries
is a party and under which one of the Retained Subsidiaries or AWS directly or

with contracts, agreements, bids and quotations entered into or made in the
ordinary course of business after the date of this Agreement and prior to the
Closing and which would fall within the foregoing categories shall be referred
to herein as the "Subcontract Agreements"). After the Distribution Date, the
Retained Subsidiary, AWS or the Contributed Subsidiary, as the case may be, that
is a party to any such Subcontract Agreement shall not agree to any amendment of
any of the terms thereof that would affect adversely the Contributed Subsidiary,
AWS or the Retained Subsidiary providing goods or disposal space or rendering
services thereunder without the prior written consent of such entity. After the
Distribution Date, the Retained Subsidiary, AWS, or the Contributed Subsidiary,
as the case may be, that is providing goods or disposal space or rendering
services under any such Subcontract Agreement on the date of this Agreement

are subject to (a) the satisfaction or waiver (as provided for therein) of all
of the conditions set forth in Sections 9.1, 9.2 and 9.3 of the Merger Agreement
and (b) the obtaining, filing or occurrence of all authorizations, consents,
orders or approvals of, or declarations or filings with, or expirations of
waiting periods imposed by, any governmental entity or other public or private
entity if the failure of any such event to occur would have a material adverse
effect on Avalon or AWS.

                             VII.  INDEMNIFICATION

     7.1   Indemnification by Avalon.  Avalon shall defend, indemnify and hold
           -------------------------
harmless USA Waste and AWS and each of their subsidiaries and their respective
officers, directors, employees, agents, successors and assigns (collectively,
the "AWS Indemnified Persons") from and against, and shall reimburse the AWS
Indemnified Persons for, each and every Loss (as

                                      C-16
<PAGE>
 
defined below) relating to, resulting from, or arising out of (i) any Assumed
Liability, or (ii) the breach of any covenant or agreement of Avalon pursuant to
this Agreement. With respect to matters not involving Actions brought or
asserted by third parties, within five days after notification from AWS
Indemnified Persons supported by reasonable documentation setting forth the
nature of the circumstances entitling AWS Indemnified Persons to indemnity
hereunder, Avalon, at no cost or expense to AWS Indemnified Persons, shall
diligently commence resolution of such matters in a manner reasonably acceptable
to AWS Indemnified Persons and shall diligently and timely prosecute such
resolution to completion; provided, however, that with respect to those claims
that may be satisfied by payment of a liquidated sum of money, Avalon shall
promptly pay the amount so claimed to the extent supported by reasonable
documentation. If any Action is commenced or threatened, the provisions of
Section 7.3 shall control.

     7.2   Indemnification by AWS.  AWS shall defend, indemnify and hold
           ----------------------
harmless Avalon and each of its subsidiaries and their respective officers,
directors, employees, agents, successors and assigns (collectively, the "Avalon
Indemnified Persons") from and against, and shall reimburse the Avalon
Indemnified Persons for, each and every Loss relating to, resulting from, or
arising out of (i) any Retained Liability or (ii) the breach of any covenant or
agreement of AWS or USA Waste pursuant to this Agreement. With respect to
matters not involving Actions brought or asserted by third parties, within five
days after notification from the Avalon Indemnified Persons supported by
reasonable documentation setting forth the nature of the circumstances entitling
the Avalon Indemnified Persons to indemnity hereunder, AWS, at no cost or
expense to the Avalon Indemnified Persons, shall diligently commence resolution
of such matters in a manner reasonably acceptable to the Avalon Indemnified
Persons and shall diligently and timely prosecute such resolution to completion;
provided, however, that with respect to those claims that may be satisfied by
payment of a liquidated sum of money, AWS shall promptly pay the amount so
claimed to the extent supported by reasonable documentation. If any Action is
commenced or threatened, the provisions of Section 7.3 shall control.
Notwithstanding the foregoing, AWS shall have no obligations under this Section
7.2 with respect to any Losses arising from a breach by AWS of any of its
representations, warranties or covenants in the Merger Agreement without regard
to any materiality limitation thereunder.

     7.3   Notice and Defense of Third-Party Claims.  If any Action shall be
           ----------------------------------------
brought or asserted under this Article VII against an indemnified party or any
successor thereto (the "Indemnified Person") in respect of which indemnity may
be sought under this Article VII from an indemnifying person or any successor
thereto (the "Indemnifying Person"), the Indemnified Person shall give prompt
written notice of such Action to the Indemnifying Person who shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
the Indemnified Person and the payment of all expenses; provided, that any delay
or failure so to notify the Indemnifying Person shall relieve the Indemnifying
Person of its obligations hereunder only to the extent, if at all, that it is
prejudiced by reason of such delay or failure. The Indemnified Person shall have
the right to employ separate counsel in any Action and to participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of the Indemnified Person unless the Indemnified Person shall in good
faith determine that there exist actual or potential conflicts of interest which
make representation by counsel for

                                      C-17
<PAGE>
 
the Indemnifying Person inappropriate. The Indemnified Person's right to
participate in the defense or response to any Action shall not be deemed to
limit or otherwise modify its rights under this Article VII. In the event that
the Indemnifying Person, within five days after notice of any such Action, fails
in writing to assume the defense thereof, the Indemnified Person shall have the
right to undertake the defense, compromise or settlement of such Action for the
account of the Indemnifying Person, subject to the right of the Indemnifying
Person to assume the defense of such Proceeding with counsel reasonably
satisfactory to the Indemnified Person at any time prior to the settlement,
compromise or final determination thereof. Anything in this Article VII to the
contrary notwithstanding, the Indemnifying Person shall not, without the
Indemnified Person's prior written consent, settle or compromise any Action or
consent to the entry of any judgment with respect to any Action for anything
other than money damages paid by the Indemnifying Person. The Indemnifying
Person may, without the Indemnified Person's prior written consent, settle or
compromise any such Action or consent to entry of any judgment with respect to
any such Action that requires solely the payment of money damages by the
Indemnifying Person and that includes as an unconditional term thereof the
release by the claimant or the plaintiff of the Indemnified Person from all
liability in respect of such Action.

     7.4   Limitations.  Avalon shall have no liability under this Article VII
           -----------
unless notice of a claim for indemnity with respect to an indemnifiable Loss in
any way related to a Terminated Employee shall have been given within two years
after the Distribution Date.

     7.5   Payment; Interest.  The Indemnifying Party shall make any payment
           -----------------
required to be made under this Article VII in cash and on demand. Any Losses or
other payments required to be paid by an Indemnifying Party under this Article
VII that are not paid within five business days of receipt by the Indemnifying
Party of the Indemnified Party's demand therefor shall thereafter be deemed
delinquent, and the Indemnifying Party shall pay to the Indemnified Party
immediately upon demand interest at a rate equal to the prime rate as quoted in
the Wall Street Journal, as such rate may change from time to time during the
period as to which such interest is calculated, plus 3%, from the date such
payment becomes delinquent to the date of payment of such delinquent sum.

     7.6   Definitions.  For purposes of this Article VII and subject to the
           -----------
provisions of Section 1.3(b) hereof, "Loss" means any loss, damage, injury,
harm, detriment, decline in value, Liability, exposure, claim, demand,
Proceeding, settlement, judgment, award, punitive damage award, fine, penalty,
fee, charge, cost or expense (including, without limitation, reasonable costs of
attempting to avoid or in opposing the imposition thereof, interest, penalties,
costs of preparation and investigation, and the reasonable fees, disbursements
and expenses of attorneys, accountants and other professional advisors), as well
as, with respect to compliance with the requirements of environmental laws,
expenses of remediation and any other remedial, removal, response, abatement,
cleanup, investigative, monitoring, or record keeping costs and expenses.

                              VIII.  MISCELLANEOUS

     8.1   Termination.  This Agreement (a) may be terminated at any time
           -----------
prior to the Distribution Date by mutual written consent of AWS and USA Waste,
or (b) shall terminate upon termination of the Merger Agreement prior to the
Merger.

     8.2   Entire Agreement.  This Agreement, together with the schedules and
           ----------------
exhibits hereto and the Confidentiality Agreement, the Tax Allocation Agreement

shall have any rights with respect to any obligations of any entity under this

party to any such waiver shall be valid only if set forth in an instrument in

of its rights under or to enforce any provision of this Agreement shall not
constitute a waiver of its rights under such provision or any other provision.

                     BALDWIN'S OHIO REVISED CODE ANNOTATED
                     TITLE XVII. CORPORATIONS--PARTNERSHIPS
                     CHAPTER 1701. GENERAL CORPORATION LAW
                            MERGER AND CONSOLIDATION
                                        


1701.85 QUALIFICATIONS OF AND PROCEDURES FOR DISSENTING SHAREHOLDERS

(A)(1)  A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.

(2)  If the proposal must be submitted to the shareholders of the corporation
involved, the dissenting shareholder shall be record holder of the shares of the
corporation as to which he seeks relief as of the date fixed for the
determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal.  Not later than ten days after the
date on which the vote on the proposal was taken at the meeting of the
shareholders, the dissenting shareholder shall deliver to the corporation a
written demand for payment to him of the fair cash value of the shares as to
which he seeks relief, which demand shall state his address, the number and
class of such shares, and the amount claimed by him as the fair cash value of
the shares.

(3)  The dissenting shareholder entitled to relief under division (C) of section
1701.84 of the Revised Code in the case of a merger pursuant to section 1701.80
of the Revised Code and a dissenting shareholder entitled to relief under
division (E) of section 1701.84 of the Revised Code in the case of a merger
pursuant to section 1701.801 of the Revised Code shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date on which
the agreement of merger was adopted by the directors of that corporation.
Within twenty days after he has been sent the notice provided in section 1701.80
or 1701.801 of the Revised Code, the dissenting shareholder shall deliver to the
corporation a written demand for payment with the same information as that
provided for in division (A)(2) of this section.

(4)  In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.

(5)  If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made.  The corporation promptly shall return such endorsed certificates to
the dissenting shareholder.  A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting

                                      D-1
<PAGE>
 
shareholder within twenty days after the lapse of the fifteen-day period, unless
a court for good cause shown otherwise directs. If shares represented by a
certificate on which such a legend has been endorsed are transferred, each new
certificate issued for them shall bear a similar legend, together with the name
of the original dissenting holder of such shares. Upon receiving a demand for
payment from a dissenting shareholder who is the record holder of uncertificated
securities, the corporation shall make an appropriate notation of the demand for
payment in its shareholder records. If uncertificated shares for which payment
has been demanded are to be transferred, any new certificate issued for the
shares shall bear the legend required for certificated securities as provided in
this paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.

(B)  Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors.  Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated.  The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded.  No answer to such a complaint is required.  Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases.  On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares.  If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value.  The appraisers have such power
and authority as is specified in the order of their appointment.  The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable.  The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final order in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505. of the
Revised Code.  If, during the pendency of any proceeding instituted under this

                                      D-2
<PAGE>
 
section, a suit or proceeding is or has been instituted to enjoin or otherwise
to prevent the carrying out of the action as to which the shareholder has
dissented, the proceeding instituted under this section shall be stayed until
the final determination of the other suit or proceeding.  Unless any provision
in division (D) of this section is applicable, the fair cash value of the shares
that is agreed upon by the parties or fixed under this section shall be paid
within thirty days after the date of final determination of such value under
this division, the effective date of the amendment to the articles, or the
consummation of the other action involved, whichever occurs last.  Upon the
occurrence of the last such event, payment shall be made immediately to a holder
of uncertificated securities entitled to such payment.  In the case of holders
of shares represented by certificates, payment shall be made only upon and
simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.

(C)  If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and, in
the case of a merger pursuant to section 1701.80 or 1701.801 of the Revised
Code, fair cash value as to shareholders of a constituent subsidiary corporation
shall be determined as of the day before the adoption of the agreement of merger
by the directors of the particular subsidiary corporation.  The fair cash value
of a share for the purposes of this section is the amount that a willing seller
who is under no compulsion to sell would be willing to accept and that a willing
buyer who is under no compulsion to purchase would be willing to pay, but in no
event shall the fair cash value of a share exceed the amount specified in the
demand of the particular shareholder.  In computing such fair cash value, any
appreciation or depreciation in market value resulting from the proposal
submitted to the directors or to the shareholders shall be excluded.

(D)(1)  The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:

(a)  The dissenting shareholder has not complied with this section, unless the
corporation by its directors waives such failure;

(b)  The corporation abandons the action involved or is finally enjoined or
prevented from carrying it out, or the shareholders rescind their adoption of
the action involved;

(c)  The dissenting shareholder withdraws his demand, with the consent of the
corporation by its directors;

(d)  The corporation and the dissenting shareholder have not come to an
agreement as to the fair cash value per share, and neither the shareholder nor
the corporation has filed or joined in a complaint under division (B) of this
section within the period provided in that division.

(2)  For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the

                                      D-3
<PAGE>
 
directors of the corporation shall be taken by the general partners of a
surviving or new partnership or the comparable representatives of any other
surviving or new entity.

(E)  From the time of the dissenting shareholder's giving of the demand until
either the termination of the rights and obligations arising from it or the
purchase of the shares by the corporation, all other rights accruing from such
shares, including voting and dividend or distribution rights, are suspended.  If
during the suspension, any dividend or distribution is paid in money upon shares
of such class or any dividend, distribution, or interest is paid in money upon
any securities issued in extinguishment of or in substitution for such shares,
an amount equal to the dividend, distribution, or interest which, except for the
suspension, would have been payable upon such shares or securities, shall be
paid to the holder of record as a credit upon the fair cash value of the shares.
If the right to receive fair cash value is terminated other than by the purchase
of the shares by the corporation, all rights of the holder shall be restored and
all distributions which, except for the suspension, would have been made shall
be made to the holder of record of the shares at the time of termination.
