                 SUBJECT TO COMPLETION, DATED NOVEMBER 1, 1995
 
                                3,172,226 SHARES
 
                            USA WASTE SERVICES, INC.
 
                                  COMMON STOCK
 
     This Prospectus covers the issuance of a maximum of 3,172,226 shares of
common stock, par value $.01 per share (the "Common Stock"), of USA Waste
Services, Inc., a Delaware corporation (the "Company"), issuable to holders of
the Company's outstanding 8 1/2% Convertible Subordinated Debentures due 2002
(the "Debentures") upon conversion of the Debentures or to Sanders Morris Mundy
Inc. (the "Purchaser") under the standby arrangements described under "Standby
Arrangements" and the reoffering to the public by the Purchaser of any Common
Stock pursuant to such standby arrangements. As of October 25, 1995, Debentures
in an aggregate principal amount of $42,032,000 were outstanding.
 
     On November 1, 1995, the Company called for redemption on December 11, 1995
(the "Redemption Date"), all of its outstanding Debentures at a redemption price
of 105.67% of the principal amount of Debentures, plus accrued interest thereon
from October 15, 1995, to the Redemption Date (the "Redemption Price"). The
Debentures (or any portion thereof which is $1,000 or an integral multiple
thereof) may be converted into the Common Stock of the Company at a conversion
price of $13.25 of principal amount of Debentures per share of Common Stock or
approximately 75.47 shares of Common Stock for each $1,000 principal amount of
Debentures at any time prior to 5:00 p.m. Eastern Time on December 1, 1995 (the
"Expiration Time"). Cash will be paid in lieu of any fractional shares of Common
Stock issuable upon conversion of the Debentures. No payment or adjustment to
the conversion price will be made on account of accrued interest on the
Debentures. ANY DEBENTURES NOT SO SURRENDERED FOR CONVERSION PRIOR TO THE
EXPIRATION TIME WILL BE REDEEMED FOR CASH ON THE REDEMPTION DATE.
 
     The Company has made arrangements with the Purchaser pursuant to which the
Purchaser has agreed to purchase from the Company, at the option of the Company,
such number of shares (the "Shares") of Common Stock equal to the number of
shares of Common Stock (the "Redemption Shares") that would have been issuable
upon conversion of the Debentures that are not surrendered for conversion on or
prior to the Expiration Time. The purchase price for such shares of Common Stock
will be an amount equal to the aggregate Redemption Price of such Debentures.
The Purchaser has agreed to remit to the Company not less than 75% of the
amount, if any, by which the aggregate net proceeds received by the Purchaser
from sales of the Shares exceeds the Redemption Price of the Shares if the
number of Redemption Shares is equal to or less than 369,811 shares and not less
than 50% of the amount, if any, by which the aggregate net proceeds received by
the Purchaser from sales of the Shares exceeds the Redemption Price of the
Shares if the number of Redemption Shares is greater than 369,811 shares. The
Purchaser may also purchase Debentures in the open market or otherwise prior to
the Expiration Time and has agreed to convert into Common Stock all Debentures
which it so purchases. See "Standby Arrangements" for a description of the
Purchaser's compensation and indemnification arrangements with the Company.
 
     SEE "RISK FACTORS" ON PAGE 6 FOR A DISCUSSION OF CERTAIN FACTORS THAT
SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS OF THE COMMON STOCK. SO LONG AS
THE MARKET PRICE OF THE COMMON STOCK IS GREATER THAN $14.18 PER SHARE AT THE
TIME OF CONVERSION, A HOLDER OF DEBENTURES WHO EXERCISES SUCH HOLDER'S
CONVERSION RIGHTS WILL RECEIVE COMMON STOCK WITH A MARKET VALUE, PLUS CASH IN
LIEU OF ANY FRACTIONAL SHARE, GREATER THAN THE AMOUNT OF CASH SUCH HOLDER WOULD
OTHERWISE BE ENTITLED TO RECEIVE UPON THE REDEMPTION OF THE DEBENTURES, BEFORE
DEDUCTING ANY APPLICABLE TRANSFER TAXES.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
      EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
         COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
          ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION
                    TO THE CONTRARY IS A CRIMINAL OFFENSE.
                                       
                              SANDERS MORRIS MUNDY

               THE DATE OF THIS PROSPECTUS IS             , 1995.
<PAGE>   3
 
     On October 30, 1995, the closing price of the Common Stock as reported on
the New York Stock Exchange Composite Tape was $20.75 per share. If a holder of
$1,000 principal amount of Debentures on that date had converted such principal
amount, such holder would have received Common Stock (and cash in lieu of a
fractional share) having a market value equal to $1,566.03, based on the closing
price of $20.75 per share. The market price of the Common Stock received upon
conversion is subject to fluctuation, and such holder may incur various
transaction costs if the Common Stock is sold. See "Price Range of Common Stock
and Dividends." Holders of Debentures are urged to obtain current information as
to the market price of the Common Stock. So long as the market price of the
Common Stock is greater than $14.18 per share at the time of conversion, a
holder of Debentures who exercises such holder's conversion rights will receive
Common Stock with a market value, plus cash in lieu of any fractional share,
greater than the amount of cash such holder would otherwise be entitled to
receive upon the redemption of the Debentures, before deducting any applicable
transfer taxes. See "Redemption of the Debentures and Alternatives to
Redemption."
 
     Prior to, on or after the Redemption Date, the Purchaser may offer shares
of Common Stock pursuant to this Prospectus directly to the public, at prices
set from time to time by it, including shares acquired pursuant to the standby
arrangements or through conversion of Debentures acquired by the Purchaser. Each
such price when set will not exceed the greater of the last sale or current
offering price of the Common Stock on the New York Stock Exchange plus the
amounts of any concession to dealers, and an offering price on any calendar day
will not be increased more than once during such day. In effecting such
transactions, the Purchaser may realize profits or losses independent of the
compensation referred to under "Standby Arrangements." The Purchaser may also
make sales to dealers at prices that represent concessions from the prices at
which such shares are then being offered to the public. The amount of such
concessions will be determined from time to time by the Purchaser. Any Common
Stock so offered is offered subject to prior sale, when, as and if received by
the Purchaser, and subject to its right to reject orders in whole or in part.
This Prospectus does not constitute an offer to sell any securities other than
the Common Stock offered by the Purchaser.
 
     The outstanding shares of Common Stock and any shares acquired through
conversion of Debentures are listed, and the Shares will be listed, on the New
York Stock Exchange (the "NYSE").
 
     IN CONNECTION WITH THIS OFFERING, THE PURCHASER MAY OVER-ALLOT OR EFFECT
TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE DEBENTURES OR
THE COMMON STOCK AT LEVELS ABOVE THOSE WHICH MIGHT OTHERWISE PREVAIL IN THE OPEN
MARKET. SUCH TRANSACTIONS MAY BE EFFECTED ON THE NEW YORK STOCK EXCHANGE, IN THE
OVER-THE-COUNTER MARKET OR OTHERWISE. SUCH STABILIZING, IF COMMENCED, MAY BE
DISCONTINUED AT ANY TIME.

PROSPECTUS IN CONNECTION WITH THE OFFERING CONTAINED HEREIN, AND, IF GIVEN OR

PERSON TO WHOM IT IS UNLAWFUL TO MAKE SUCH OFFER OR SOLICITATION. NEITHER THE
DELIVERY OF THIS PROSPECTUS NOR ANY SALE HEREUNDER SHALL, UNDER ANY

                                  THE COMPANY
 
     USA Waste is the fourth largest integrated solid waste management company
in North America and serves municipal, commercial, industrial and residential
customers in 21 states. The Company's solid waste management services include
collection, transfer and disposal operations and, to a lesser extent, recycling
and certain other waste management services. USA Waste owns or operates 29
landfills, 21 transfer stations and 42 collection operations and serves more
than 450,000 customers.
 
     Approximately 54% of the Company's revenues for the six months ended June
30, 1995 was attributable to collection operations, approximately 30% was
attributable to landfill operations and approximately 9% was from transfer
operations. Of the collection revenues, approximately 44%, 24% and 32% were from
commercial, residential, and industrial customers, respectively. The Company
focuses primarily on residential, commercial and permanent roll-off customers
because such customers tend to provide more predictable waste stream volumes.
The Company's average landfill volume for the three months ended June 30, 1995
was approximately 23,500 tons per day.
 
     The Company intends to capitalize on the consolidation in the solid waste
management industry. Key elements of the Company's strategy include (i)
increasing productivity and operating efficiencies in existing and acquired
operations, (ii) increasing revenues and enhancing profitability through tuck-in
acquisitions and (iii) expanding into new markets through acquisitions. The
Company seeks to become the low cost operator in each of its markets by
increasing productivity and operating efficiencies through implementation of
uniform administrative systems, consolidation of collection routes, improvement
of equipment utilization, and increases in employee productivity through
incentive compensation and training programs. The Company regularly pursues
opportunities to expand its services through the acquisition of additional solid
waste management businesses and operations that can be effectively integrated
with the Company's existing operations, and pursues acquisitions in new markets
where the Company believes it can strengthen its overall competitive position as
a national provider of integrated solid waste management services.
 
     The Company's executive offices are located at 5400 LBJ Freeway, Suite
300 -- Tower One, Dallas, Texas 75240 (telephone (214) 383-7900). The Company
was organized in 1995 as a successor to USA Waste Services, Inc., an Oklahoma
corporation organized in 1987. As used in this Prospectus, the terms "the
Company" and "USA Waste" refer to USA Waste Services, Inc., a Delaware
corporation and its subsidiaries.
 
                              RECENT DEVELOPMENTS
 
     The Company materially expanded its operations and markets with its
acquisition of Chambers Development Company, Inc. ("Chambers") on June 30, 1995
(the "Chambers Merger"). With the addition of the Chambers operations, which
include significant landfill capacity as well as collection and transfer station
operations, the Company established its presence in the Mid-Atlantic and
southeastern regions of the United States. Since the Chambers Merger, the
Company has continued to expand its operations and revenue base through a series
of smaller acquisitions that complemented and expanded the Company's operations.
The Company has completed nine acquisitions since the Chambers Merger resulting
in the addition of four landfills, eight collection operations and eight
transfer stations. The Company issued an aggregate of 2,453,000 shares of its
Common Stock and paid an aggregate of $11.4 million in cash in connection with
these transactions. The acquired operations are based in Arkansas, Georgia,
Missouri, Pennsylvania, Texas and Virginia.
 
     In August 1995, the Company entered into an agreement with the Town of
North Hempstead Solid Waste Management Authority in North Hempstead, New York
for the management of its solid waste disposal, transfer, transport and
recycling operations. The contract has a 15-year term unless terminated earlier
in accordance with the agreement (such as in the case of an event of default)
and is expected to provide the Company annual revenues of approximately $9
million.
 
     On October 6, 1995, the Company completed a public offering (the "1995
Offering") of 6,345,625 shares of Common Stock at a price of $19.625 per share.
The Company realized proceeds of $118,398,183 before deducting expenses payable
by the Company, estimated at $550,000. The Company applied approximately
 
                                        5
<PAGE>   7
 
$29,462,500 of the net proceeds to repayment of the term loan under its bank
credit facility. The balance of the net proceeds was used to reduce amounts
outstanding under the revolving credit portion of the Company's credit facility.
Such amounts may be redrawn by the Company as its needs dictate for use in the
expansion of its business, including acquisitions and for general corporate
purposes.
 
                                  RISK FACTORS
 
     In addition to the other information set forth in this Prospectus, the
following factors should be considered by prospective investors when evaluating
an investment in the Common Stock of the Company.
 
ABILITY TO MANAGE AND MAINTAIN GROWTH
 
     The Company has experienced rapid growth, primarily through acquisitions.
The Company's financial results and prospects depend in large part on its
ability to successfully manage and improve the operating efficiencies and
productivity of these acquired operations. In particular, there can be no
assurance that the Company will able to successfully integrate the operations of
Chambers, the Company's largest acquisition to date. Moreover, the ability of
the Company to continue to grow will depend on a number of factors, including
competition from other waste management companies, availability of attractive
acquisition opportunities, availability of working capital, ability to maintain
operating margins and the management of costs in a changing regulatory
environment. The Company is continually seeking acquisition opportunities and
believes that there exists a substantial number of potentially attractive
consolidation opportunities in the solid waste management industry. The Company
may pursue significant acquisitions if they can be achieved on acceptable terms.
There can be no assurance that the Company will be able to continue to expand
and successfully integrate operations.
 
HIGH DEGREE OF LEVERAGE; NEED FOR CAPITAL
 
     The long-term debt of the Company, including current maturities, as of
October 31, 1995, was approximately $400 million. Although the conversion of all
of the Debentures will eliminate a portion of such indebtedness, the Company
will continue to maintain significant amounts of debt and expects to require
additional capital from time to time to pursue its acquisition strategy and to
fund internal growth. A portion of the Company's future capital requirements may
be provided through future debt incurrences or issuances of equity securities.
Future events or conditions that could adversely affect the Company's operations
or financial condition may prevent the Company from fulfilling its obligations
under its debt agreements or may limit the Company's ability to incur additional
indebtedness or issue equity securities.
 
PROFITABILITY MAY BE AFFECTED BY COMPETITION
 
     The waste management industry is highly competitive and requires
substantial capital resources. The industry consists of a few large national
waste management companies as well as numerous local and regional companies of
varying sizes and financial resources. The largest national waste management
companies have significantly greater financial resources than the Company.
Competition may also be affected by the increasing national emphasis on
recycling, composting, incineration, and other waste reduction programs that
could reduce the volume of solid waste collected or deposited in landfills.
 
POTENTIAL ADVERSE EFFECT OF GOVERNMENT REGULATIONS
 
     The Company's operations are subject to, and substantially affected by,
extensive federal, state and local laws, regulations, orders and permits, which
govern environmental protection, health and safety, zoning and other matters.
These regulations may impose restrictions on the Company's operations that could
adversely affect the Company's results, such as limitations on the expansion of
disposal facilities, limitations on or banning disposal of out-of-state waste or
certain categories of waste, or mandates regarding the disposal of solid waste.
Because of heightened public concern, companies in the waste management
business, including the Company, may become subject to judicial and
administrative proceedings involving federal, state or local agencies. These
governmental agencies may seek to impose fines on the Company or to revoke or
deny renewal
 
                                        6
<PAGE>   8
 
of the Company's operating permits or licenses for violations of environmental
laws or regulations or to require the Company to remediate environmental
problems at its sites or nearby properties, or resulting from its or its
predecessors' transportation and collection operations, all of which could have
a material adverse effect on the Company. The Company may also be subject to
actions brought by individuals or community groups in connection with the
permitting or licensing of its operations, any alleged violations of such
permits and licenses, or other matters.
 
POTENTIAL ENVIRONMENTAL LIABILITY
 
     The Company is subject to liability for environmental damage its landfills,
transfer stations and collection operations have caused or may cause nearby
landowners, particularly as a result of the contamination of drinking water
sources or soil, including damage resulting from conditions existing prior to
the acquisition of such assets or operations by the Company. The Company may
also be subject to liability for any off-site environmental contamination caused
by pollutants or hazardous substances the transportation, treatment or disposal
of which was arranged for by the Company or the predecessor owner of operations
or assets acquired by the Company. Any substantial liability for environmental
damage could materially adversely affect the Company's operating results and
financial condition.
 
DEBENTUREHOLDER CONSIDERATIONS ON CONVERSION OR REDEMPTION
 
     On October 30, 1995, the closing price of the Common Stock as reported on
the New York Stock Exchange Composite Tape was $20.75 per share. If a holder of
$1,000 principal amount of the Debentures on that date had converted such
principal amount, such holder would have received Common Stock (and cash in lieu
of a fractional share) having a market value equal to $1,566.03, based on the
closing price of $20.75 per share. The market price of the Common Stock received
upon conversion is subject to fluctuation, and such holder may incur various
transaction costs if the Common Stock is sold. Holders of Debentures should
obtain current information as to the market price of the Common Stock. So long
as the market price of the Common Stock is greater than $14.18 per share at the
time of conversion, a holder of Debentures who exercises such holder's
conversion rights will receive Common Stock with a market value, plus cash in
lieu of any fractional share, greater than the amount of cash such holder would
otherwise be entitled to receive upon the redemption of the Debentures, before
deducting any applicable transfer taxes. See "Redemption of Debentures and
Alternatives to Redemption."
 
                                USE OF PROCEEDS
 
     The net proceeds from the sale of the Common Stock to the Purchaser
pursuant to the arrangements described under "Standby Arrangements" will be used
to redeem any Debentures not surrendered for conversion. Any other amounts
received by the Company from the Purchaser pursuant to the profit-sharing
arrangement described under "Standby Arrangements" will be used for general
corporate purposes. The amount of such proceeds is not determinable at this
time. The Company will not receive any cash proceeds from the issuance of Common
Stock upon conversion of the Debentures.

            REDEMPTION OF DEBENTURES AND ALTERNATIVES TO REDEMPTION
 
     The Company has called for redemption at 5:00 p.m., Eastern Time, on
December 11, 1995 (the "Redemption Date"), all of the Company's outstanding
Debentures. As of October 25, 1995, $42,032,000 principal amount of Debentures
was outstanding.
 
     The following alternatives are available to holders of Debentures:
 
     1. Conversion into Common Stock. Convert the Debentures (or any portion
thereof which is $1,000 or an integral multiple thereof) into the Common Stock
of the Company at a conversion price of $13.25 of principal amount of Debentures
per share of Common Stock or approximately 75.47 shares of Common Stock for each
$1,000 principal amount of Debentures. Cash will be paid in lieu of any
fractional share in an amount equal to such fraction multiplied by the last
reported sale price per share of Common Stock, regular way, on the day prior to
the day of conversion or, if no such sale takes place on such day, the average
of the reported closing bid and asked prices, regular way, on the NYSE. No
payment or adjustment to the conversion price will be made on account of accrued
interest on the Debentures. On October 30, 1995, the last reported sale price of
the Common Stock on the NYSE Composite Tape was $20.75 per share. On the basis
of such last reported sale price of the Common Stock, 75.47 shares of the Common
Stock had a value (including cash in lieu of any fractional share, determined as
set forth above) of $1,566.03. THE CONVERSION RIGHT EXPIRES AT 5:00 P.M.,
EASTERN TIME, ON DECEMBER 1, 1995.
 
     Substantially all of the Debentures are currently held in book-entry form
through the facilities of The Depository Trust Company (the "Depository").
Accordingly, in order for a beneficial owner of an interest in a Debenture to
exercise such owner's conversion rights, such owner must comply with the
procedures of the Depository, if a participant in the Depository (a
"participant"), or if such owner is not a participant in the Depository, through
the procedures of the participant through which such owner owns its interest in
the Debentures, to effect a conversion.
 
     The Company will decide, in its sole discretion, all questions as to the
form of documents and the validity, eligibility (including time of receipt) and
acceptance for conversion by the Company of any Debentures. Any defect or
irregularity in the surrender or delivery of any document in connection with the
conversion of Debentures may result in such Debentures not being converted into
Common Stock and, therefore, being redeemed on the Redemption Date.
 
     SINCE IT IS THE TIME OF ACTUAL RECEIPT THAT DETERMINES WHETHER DEBENTURES
HAVE BEEN PROPERLY PRESENTED FOR CONVERSION, SUFFICIENT TIME SHOULD BE ALLOWED
FOR A BOOK-ENTRY TRANSFER TO BE MADE, PRIOR TO 5:00 P.M., EASTERN TIME, ON
DECEMBER 1, 1995. DEBENTURES NOT ACTUALLY RECEIVED FOR CONVERSION BY THE TRUSTEE
PRIOR TO SUCH TIME WILL BE REDEEMED AS SET FORTH BELOW.
 
     2. Sale in Open Market. Sell the Debentures in the open market at
prevailing prices. Holders of Debentures who wish to sell their Debentures in
the open market should consult with their own advisors regarding if and when
they should sell their Debentures and the tax consequences thereof. Holders of
Debentures may incur various fees and expenses in connection with any such sale.
 
     3. Redemption. Surrender the Debentures for redemption. Pursuant to the
terms of the Indenture between the Company and State Street Bank and Trust
Company as successor to The First National Bank of Boston, as Trustee (the
"Trustee"), dated as of September 1, 1992, holders of Debentures will be
entitled to receive upon redemption 105.67% of the principal amount of
Debentures, plus accrued interest thereon from October 15, 1995, to the
Redemption Date (the "Redemption Price"). The holder of $1,000 principal amount
of Debentures redeemed at the Redemption Price would receive $1,070.16 in cash.
Payment of the Redemption Price will be made by the Trustee, as redemption
agent, on and after the Redemption Date upon receipt of the Debentures. On and
after the Redemption Date, interest will cease to accrue (unless the Company
defaults in the payment of the Redemption Price) and holders of Debentures will
not have any rights as such holders other than the right to receive the
Redemption Price upon such surrender for redemption. All Debentures outstanding
on the Redemption Date will be deemed to be redeemed by the
 
                                        8
<PAGE>   10
 
Company, whether or not they have been surrendered for redemption. Holders of
Debentures should refer to the Notice of Redemption issued by the Trustee for
information concerning how and where the Debentures are to be surrendered for
payment of the Redemption Price.
 
     DEBENTURES NOT ACTUALLY RECEIVED FOR CONVERSION BY THE TRUSTEE PRIOR TO
5:00 P.M., EASTERN TIME, ON DECEMBER 1, 1995, WILL BE REDEEMED AS SET FORTH
ABOVE ON THE REDEMPTION DATE.
 
     Based on the above-stated last reported sale price of the Common Stock on
October 30, 1995, the market value of the Common Stock into which $1,000
principal amount of Debentures is convertible (including cash in lieu of any
fractional share, determined as set forth above) would be $1,566.03, which
amount is higher than the amount ($1,070.16) to be received upon redemption. The
market price of the Common Stock received upon conversion, however, is subject
to fluctuation, and a holder of Debentures may incur various transaction costs
if such Common Stock is sold. Holders of Debentures are urged to obtain current
market quotations for the Common Stock.
 
     SO LONG AS THE MARKET PRICE OF THE COMMON STOCK IS GREATER THAN $14.18 PER
SHARE AT THE TIME OF CONVERSION, A HOLDER OF DEBENTURES WHO CONVERTS HIS OR HER
DEBENTURES WILL RECEIVE COMMON STOCK AND CASH IN LIEU OF ANY FRACTIONAL SHARE
(DETERMINED AS SET FORTH ABOVE) WITH A MARKET VALUE GREATER THAN THE AMOUNT OF
CASH RECEIVABLE UPON THE REDEMPTION OF THE DEBENTURES.

                   PRICE RANGE OF COMMON STOCK AND DIVIDENDS
 
     The Common Stock is traded on the NYSE under the symbol "UW." Prior to July
20, 1993, the Common Stock was traded in the over-the-counter market and quoted
on the NASDAQ National Market System ("Nasdaq/NMS"). The following table sets
forth the high and low per share closing prices for the Common Stock for the
calendar quarters indicated as reported on the NYSE for periods on and after
July 20, 1993, and the high and low sales prices for the Common Stock as quoted
on the Nasdaq/NMS for periods prior to July 20, 1993.

     According to the Company's transfer agent, on September 30, 1995, there
were 4,363 holders of record of the Company's Common Stock.
 
     The Company has never paid cash dividends on its Common Stock. Envirofil
paid dividends on its preferred stock prior to its acquisition by the Company;
the holders of such preferred stock received Common Stock in such acquisition,
and no dividends have been paid by the Company. The Board of Directors of the
Company presently intends to retain any earnings in the foreseeable future for
the Company's business. In addition, payment of dividends on the Common Stock is
restricted by the terms of the Company's bank credit agreement.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
 
     The following selected consolidated financial data for the Company for each
of the three years in the period ended December 31, 1994, have been derived from
the audited consolidated financial statements of the Company and for the
three-month and six-month periods ended June 30, 1994 and 1995, have been
derived from the unaudited consolidated financial statements of the Company. The
summary consolidated financial data should be read in conjunction with the
separate consolidated financial statements and the related notes thereto of the
Company and Management's Discussion and Analysis of Financial Condition and
Results of Operations incorporated by reference herein. See "Incorporation of
Certain Information by Reference."
 
     The data set forth below include the accounts of all companies acquired
through June 30, 1995. Companies acquired in transactions accounted for as
poolings of interests have been combined as though these companies had always
been members of the same operating group. Accordingly, such data have been
restated throughout all relevant periods reported. The accounts of businesses
acquired in transactions accounted for as purchases are included from their
respective dates of acquisition.
 
     The unaudited data for the three months and six months ended June 30, 1994
and 1995, include, in the opinion of the Company's management, all adjustments
(which include only normal recurring adjustments) necessary to present fairly
the information for such periods. The results of operations of the interim
periods are not necessarily indicative of the results that may be expected for
the full year.

(1) Reflects nonrecurring costs related to the merger of the Company and
    Envirofil, Inc. on May 27, 1994.
 
(2) Reflects nonrecurring costs related to the Chambers Merger, consisting of
    transaction costs ($11.9 million), severance and other termination benefits
    ($9.5 million), and nonrecurring costs relating to the integration of the
    operations of the combined companies ($3.7 million).
 
(3) Income (loss) from operations excluding unusual items and merger costs was
    $16.5 million and $29.6 million for the three and six months ended June 30,
    1995, respectively.
 
(4) The Company may utilize Chambers' net operating loss carryforwards to offset
    future income for federal income tax purposes. As a result of an issuance
    of Common Stock in connection with one of the acquisitions in August 1995,
    an "ownership change" within the meaning of Section 382 of the Internal
    Revenue Code of 1986, as amended, occurred, which will limit the Company's
    potential utilization of Chambers' net operating loss carry forwards to a
    maximum of approximately $32 million on an annual basis. In connection with
    the settlement relating to certain stockholder litigation of Chambers, the
    Company made a settlement payment of $75.6 million for the benefit of
    certain Chambers stockholders. The portion of such payment that is not
    characterized as a return of capital to such stockholders may be available
    as a deduction to the Company to offset taxable income.
 
(5) Net income (loss) before unusual items, merger costs and early redemption
    premiums, fees and nonrecurring interest was $7.7 million and $11.6 million
    for the three and six months ended June 30, 1995, respectively.

    1995 Offering, the net proceeds from which in the amount of approximately
    $117.9 million, were used to repay indebtedness outstanding under the

    Company in connection with the issuance of 137,500 shares of Common Stock
    upon the exercise of stock purchase warrants, and (iv) the effect of
    retirement of the Debentures, assuming all Debentures are converted to
    Common Stock. See "Capitalization."

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a general summary of certain anticipated United States
federal income tax consequences to a holder of Debentures of the conversion,
redemption, or sale of the Debentures. It deals only with Debentures held as
capital assets and not with special classes of holders, such as dealers in
securities or currencies, banks, tax-exempt organizations, life insurance
companies, persons that hold Debentures that are a hedge or that are hedged
against currency risks or that are part of a straddle or conversion transaction,
persons that are not United States holders, or persons whose functional currency
is not the U.S. dollar. A United States holder is a beneficial owner that is (i)
a citizen or resident of the United States, (ii) a domestic corporation, or
(iii) otherwise subject to United States federal income taxation on a net income
basis in respect of a Debenture. The summary is based on the Internal Revenue
Code of 1986, as amended (the "Code"), its legislative history, existing and
proposed regulations thereunder, published rulings and court decisions, all as
currently in effect and all subject to change at any time, perhaps with
retroactive effect. The Company has not requested a ruling from the Internal
Revenue Service (the "Service") with respect to the matters discussed herein.
 
     HOLDERS OF DEBENTURES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE
CONSEQUENCES, IN THEIR PARTICULAR CIRCUMSTANCES, UNDER THE CODE AND THE LAWS OF
ANY OTHER TAXING JURISDICTION, OF THE CONVERSION, SALE, OR REDEMPTION OF THE
DEBENTURES.
 
CONVERSION
 
     In general, no gain or loss should be recognized by a holder of Debentures
upon the conversion of a Debenture into Common Stock of the Company, except to
the extent of any gain realized upon the receipt of cash in lieu of fractional
shares. A Debentureholder's basis in the Common Stock received on conversion
(including any fractional shares, which are deemed received and immediately
disposed of) generally will equal such holder's basis at the time of conversion
in the Debenture converted. A Debentureholder's holding period for the Common
Stock received on conversion will include such holder's holding period of the
Debenture converted.
 
SALE OR REDEMPTION
 
     In general, the sale or redemption of a Debenture will result in the
recognition of gain or loss to a holder of Debentures in an amount equal to the
difference between (i) the cash received in exchange for the Debenture less the
amount attributable to accrued interest not previously included in income (which
amount is taxable as ordinary income) and (ii) such holder's adjusted tax basis
in the Debentures. Except as discussed below under "Market Discount," such gain
or loss will be a capital gain or loss and will be long-term gain or loss if, at
the time of such disposition, the Debentures had been held for more than one
year.
 
MARKET DISCOUNT
 
     Special rules will apply to Debentures acquired with market discount. A
market discount note is, generally, a Debenture the stated redemption price at
maturity of which exceeds the Debentureholder's basis in the Debenture
immediately after acquisition. Generally, any gain recognized on the sale or
redemption of a market discount Debenture will be treated as ordinary income to
the extent of the accrued market discount on such note not previously included
in income. Market discount accrues either ratably or at a constant yield to
maturity, at the election of the Debentureholder. A holder of a market discount
Debenture also may elect to take market discount into income as it accrues.
 
     Although the matter is not free from doubt, a holder of a Debenture with
market discount should not have to recognize income on the conversion of the
Debenture, even with respect to market discount that has accrued but has not
been taken into account. Market discount not recognized on conversion will carry
over to the Common Stock acquired upon conversion thereof and will be recognized
as ordinary income to the extent of gain recognized upon the disposition of such
Common Stock, including any deemed disposition of fractional shares of Common
Stock for cash at the time of conversion.
 
                                       14
<PAGE>   16
 
BACKUP WITHHOLDING
 
     In general, backup withholding at a rate of 31% will apply to payments of
the proceeds of a sale, redemption or conversion of a Debenture if the holder is
not an "exempt recipient" and fails to provide an accurate taxpayer
identification number or to report all interest and dividends required to be
shown on its federal income tax returns. Individuals generally are not exempt
recipients, whereas corporations and certain other entities generally are exempt
recipients. To prevent backup withholding from the payment of cash in lieu of a
fractional share or the payment of the Redemption Price, any holder (other than
an exempt payee such as a corporation or tax-exempt organization) who has not
previously provided a valid IRS Form W-9 relating to the holder's Debentures
should provide a completed Form W-9 upon surrendering Debentures for conversion
or redemption.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized to issue 150,000,000 shares of Common Stock, par
value $0.01 per share, of which 53,848,249 shares were outstanding at September
30, 1995. The Company is also authorized to issue 10,000,000 shares of Preferred
Stock, $.01 par value (the "Preferred Stock"), none of which are outstanding.
 
COMMON STOCK
 
     Each holder of Common Stock is entitled to one vote per share held of
record on each matter submitted to stockholders. Cumulative voting for the
election of directors is not permitted, and the holders of a majority of shares
voting for the election of directors can elect all members of the Board of
Directors.
 
     Subject to the rights of any holders of Preferred Stock, holders of record
of shares of Common Stock are entitled to receive ratably dividends when and if
declared by the Board of Directors out of funds of the Company legally available
therefor. In the event of a voluntary or involuntary winding up or dissolution,
liquidation, or partial liquidation of the Company, holders of Common Stock are
entitled to participate ratably in any distribution of the assets of the
Company, subject to any prior rights of holders of any outstanding Preferred
Stock.
 
     Holders of Common Stock have no conversion, redemption, or preemptive
rights. All outstanding shares of Common Stock are, and the Shares offered
hereby will be, upon issuance and sale, validly issued, fully paid, and
nonassessable.
 
PREFERRED STOCK
 
     The Board of Directors is authorized, without further approval of the
stockholders, to issue the Preferred Stock in series and with respect to each
series, to fix its designations, relative rights (including voting, dividend,
conversion, sinking fund, and redemption rights), preferences (including with
respect to dividends and upon liquidation), privileges, and limitations. The
Board of Directors of the Company, without stockholder approval, may issue
Preferred Stock with voting and conversion rights, both of which could adversely
affect the voting power of the holders of Common Stock, and dividend or
liquidation preferences that would restrict Common Stock dividends or adversely
affect the assets available for distribution to holders of shares of Common
Stock upon the Company's dissolution.
 
AUTHORIZED BUT UNISSUED SHARES
 
     Authorized but unissued shares of Common Stock or Preferred Stock can be
reserved for issuance by the Board of Directors from time to time without
further stockholder action for proper corporate purposes, including stock
dividends or stock splits, raising equity capital, and structuring future
corporate transactions, including acquisitions.

TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is The First National
Bank of Boston, Boston, Massachusetts.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     The Certificate of Incorporation of the Company provides that the directors
of the Company shall not be liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the Delaware General Corporation Law (the "DGCL"). The
foregoing limitation does not eliminate or limit the liability of a director for
any breach of a director's duty of loyalty to the Company or its stockholders,
for acts or omissions not in good faith or which involved intentional misconduct
or a knowing violation of law, for any transaction from which the director
derived an improper personal benefit, or for approval of the unlawful payment of
a dividend or an unlawful stock purchase or redemption. The Certificate of
Incorporation of the Company also provides that the Company shall indemnify, and
advance litigation expenses to, its officers, directors, employees, and agents
to the fullest extent permitted by the DGCL and all other laws of the State of
Delaware.
 
     The DGCL provides that the Company has the power to indemnify any person
who is sued or threatened to be made a named party in a proceeding, other than
an action by or in the right of the Company, because such person is or was a
director, officer, employee, or agent of the Company or is or was serving at the
request of the Company as a director, officer, employee, or agent of another
corporation, partnership, joint venture, trust, or other enterprise, against
expenses actually and reasonably incurred by him in connection with such
proceeding. In order to be indemnified, the person must have (1) acted in good
faith; (2) acted in a manner he reasonably believed to be in or not opposed to
the best interests of the Company; and (3) with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
indemnification includes attorneys' fees, judgments, fines, and amounts paid in
settlement.
 
     The DGCL also provides that the Company may indemnify any person who is
sued or threatened to be made a named party in a proceeding by or in the right
of the Company to procure a judgment in its favor because such person is or was
a director, officer, employee, or agent of the Company, or is or was serving at
the request of the Company as a director, officer, employee, or agent of another
corporation, partnership, joint venture, trust, or other enterprise. In order to
be indemnified, the person must have conducted himself in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company. No indemnification may be made, however, with respect to any claim,
issue, or matter as to which such person shall have been judged to be liable to
the Company unless and only to the extent that the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnification for such expenses which the
court shall deem proper.
 
     Indemnification by the Company is subject to a determination that the
director, officer, employee, or agent has met the applicable standard of
conduct. The determination must be made (1) by a majority vote of a quorum of
the Board of Directors, consisting only of directors who were not parties to
such action, suit or proceeding; (2) if such a quorum cannot be obtained, or
even if obtainable, if a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion; or (3) by the stockholders of
the Company.
 
     The Company has entered into an Indemnification Agreement with each of its
directors and executive officers (the "Indemnitees") pursuant to which the
Company has agreed to indemnify and hold each of the Indemnitees harmless from
and against all expenses, including reasonable fees and expenses of counsel, and
all liabilities, including the amounts of any judgments, fines, penalties,
excise taxes, and amounts paid in settlement actually incurred by an Indemnitee
in connection with any threatened, pending or completed claim, action (including
any action by or in the right of the Company), suit, or proceeding (whether
formal or informal, or civil, criminal, administrative, legislative,
arbitrative, or investigative) in respect of which the Indemnitee is, was, or at
any time becomes, or is threatened to be made, a party, witness, subject, or
target, by reason of the fact that the Indemnitee is or was an authorized
representative of the Company; provided,
 
                                       16
<PAGE>   18
 
however, no indemnity shall be paid on account of the Indemnitee's conduct that
is finally adjudged to constitute willful misconduct or to have been knowingly
fraudulent, deliberately dishonest, or from which the Indemnitee derives an
improper personal benefit.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, or person controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.
 
                              STANDBY ARRANGEMENTS
 
     Under the terms and subject to the conditions of a Standby Agreement (the
"Standby Agreement"), Sanders Morris Mundy Inc. (the "Purchaser") has agreed to
purchase from the Company the Redemption Shares.
 
     The Purchaser may purchase Debentures in the market or otherwise prior to
the Expiration Date and has agreed to convert into Common Stock all of the
Debentures which it so purchases.
 
     The Company has been advised that the Purchaser proposes to offer any
Common Stock purchased from the Company or acquired on conversion by the
Purchaser of Debentures for resale as set forth on the cover page of this
Prospectus. The Purchaser may also make sales to certain securities dealers at
prices which may reflect concessions from the prices at which the shares are
then being offered to the public. The amount of such concessions will be
determined from time to time by the Purchaser. The sales of Common Stock so
offered are offered by the Purchaser subject to prior sale, when, as, and if
received by the Purchaser, and subject to its right to reject orders in whole or
in part. The Purchaser has agreed to remit to the Company not less than 75% of
the amount, if any, by which the aggregate net proceeds received by the
Purchaser from sales of the Shares exceeds the Redemption Price of the Shares if
the number of Redemption Shares is equal to or less than 369,811 and not less
than 50% of the amount, if any, by which the aggregate net proceeds received by
the Purchaser from sales of the Shares exceeds the Redemption Price of the
Shares if the number of Redemption Shares is greater than 369,811.
 
     Pursuant to the Standby Agreement, the Company has agreed to pay to the
Purchaser for the commitments undertaken by it under the Standby Agreement (i)
$200,000 (the "Standby Fee"), (ii) the Purchaser's out-of-pocket expenses
incurred in connection herewith, including fees and disbursements of counsel,
and (iii) $.40 per share for each share of Common Stock purchased by the
Purchaser pursuant to the Standby Agreement. If the Purchaser does not purchase
any Shares, in addition to paying the Purchaser the Standby Fee the Company has
agreed to reimburse the Purchaser for the fees and disbursements of its counsel.
 
     During the period beginning from the date of this Prospectus and continuing
to and including the Redemption Date, and, if the Purchaser purchases any
Shares, further continuing and including the date ending 90 days after the
Redemption Date, the Company has agreed not to offer, sell, contract to sell or
otherwise dispose of, any shares of Common Stock of the Company, any securities
of the Company substantially similar to the Common Stock or any securities
convertible into or exchangeable for shares of Common Stock or any such
substantially similar security (except for any securities, issued, offered, sold
or disposed of by the Company to its stock option and other benefit plans
maintained for its officers, directors, and employees or Common Stock issued or
distributed in connection with the conversion of any security of the Company
outstanding on the date of the Prospectus) without the Purchaser's prior written
consent.
 
     The Company has agreed to indemnify the Purchaser against certain
liabilities, including liabilities under the Securities Act or to contribute to
payments the Purchaser may be required to make in respect thereof.
 
     The Purchaser may assist in the solicitation of conversions by holders of
Debentures but will receive no commission therefor.
 
     Purchaser has from time to time performed various investment banking and
other financial services for the Company, for which it has received customary
compensation. These services have included acting as a
 
                                       17
<PAGE>   19
 
managing underwriter of the public offering of the Debentures. Two of the
Company's directors, John E. Drury and George L. Ball, are directors and
shareholders of the Purchaser.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 102(b)(7) of the Delaware General Corporation Law provides that the
certificate of incorporation of a Delaware corporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that such provision shall not eliminate or limit the
liability of a director: (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involved intentional misconduct or a knowing violation of law,
(iii) under Section 174 of this title, or (iv) for any transaction from which
the director derived an improper personal benefit. No such provision shall
eliminate or limit the liability of a director for any act or omission occurring
prior to the date when such provision becomes effective.
 
     The Restated Certificate of Incorporation of the registrant includes the
following provisions:
 
          Seventh: No director of the Corporation shall be personally liable to
     the Corporation or its stockholders for monetary damages for breach of
     fiduciary duty as a director, provided that this provision shall not
     eliminate or limit the liability of a director for liability (i) for any
     breach of the director's duty of loyalty to the Corporation or its
     stockholders, (ii) for acts or omissions not in good faith or which involve
     intentional misconduct or a knowing violation of law, (iii) under Section
     174 of the General Corporation Law of Delaware or (iv) for any transaction
     from which the director derived an improper personal benefit. If the
     General Corporation Law of Delaware hereafter is amended to authorize the
     further elimination or limitation of the liability of directors, then the
     liability of a director of the Corporation, in addition to the limitation
     on personal liability provided herein, shall be limited to the fullest
     extent permitted by the amended General Corporation Law of Delaware. Any
     repeal or modification of this paragraph by the stockholders of the
     Corporation shall be prospective only, and shall not adversely affect any
     limitation on the personal liability of a director of the Corporation
     existing at the time of such repeal or modification. Neither this Restated
     Certificate of Incorporation nor any amendment, alteration, or repeal of
     this Article, nor the adoption of any provision of the Restated Certificate
     of Incorporation inconsistent with this Article, shall adversely effect,
     eliminate, or reduce any right or protection of a director of the
     Corporation hereunder with respect to any act, omission or matter
     occurring, or any action, suit, or claim that, but for this Article, would
     accrue or arise, prior to the time of such amendment, modification, repeal,
     or adoption of an inconsistent provision. All references in this Article to
     a "director" shall also be deemed to refer to such person or persons, if
     any, who pursuant to a provision of the Restated Certificate of
     Incorporation in accordance with subsection (a) of Section 141 of the
     Delaware General Corporation Law, exercise or perform any of the powers or
     duties otherwise conferred or imposed upon the board of directors by the
     Delaware General Corporation Law.

<PAGE>   22
 
     Section 145 of the Delaware General Corporation Law provides as follows:
 
     145. INDEMNIFICATION OF OFFICERS DIRECTORS, EMPLOYEES AND AGENTS;
INSURANCE. -- (a) A corporation may indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines, and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
 
     (b) A corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee, or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees),
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.
 
     (c) To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsection (a) or (b) of this section,
or in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees), actually and reasonably incurred
by him in connection therewith.
 
     (d) Any indemnification under the provisions of subsection (a) or (b) of
this section (unless ordered by a court) shall be made by the corporation only
as authorized in the specific case upon a determination that indemnification of
the director, officer, employee or agent is proper in the circumstances because
he has met the applicable standard of conduct set forth in subsection (a) or (b)
of this section. Such determination shall be made (1) by a majority vote of
directors who were not parties to such action suit or proceeding even though
less than a quorum, or (2) if there are no such directors, or if such directors
so direct, by independent legal counsel in a written opinion, or (3) by the
stockholders.
 
     (e) Expenses (including attorneys' fees) incurred by an officer or director
in defending any civil, criminal, administrative, or investigative action, suit
or proceeding may be paid by the corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it shall ultimately
be determined that he is not entitled to be indemnified by the corporation as
authorized by the provisions of this section. Such expenses (including
attorneys' fees) incurred by other employees and agents may be so paid upon such
terms and conditions, if any, as the board of directors deems appropriate.
 
     (f) The indemnification and advancement of expense provided by, or granted
pursuant to, the other subsections of this section shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any bylaw, agreement, vote of stockholders
 
                                      II-2
<PAGE>   23
 
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.
 
     (g) A corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was servicing at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this section.
 
     (h) For purposes of this section, references to "the corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
any person who is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this section with respect to the resulting or
surviving corporation as he would have with respect to such constituent
corporation if its separate existence had continued.
 
     (i) For purposes of this section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services, by such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this
section.
 
     (j) The indemnification and advancement of expenses provided by, or granted
pursuant to, this section, unless otherwise provided when authorized or
ratified, shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.
 
     (k) The Court of Chancery is hereby vested with exclusive jurisdiction to
hear and determine all actions for advancement of expenses or indemnification
brought under this section or under any bylaw, agreement, vote of stockholders
or disinterested directors, or otherwise. The Court of Chancery may summarily
determine a corporation's obligation to advance expenses (including attorneys'
fees).
 
     The Restated Certificate of Incorporation of the registrant includes the
following provision:
 
          Eighth: This Corporation shall, to the maximum extent permitted from
     time to time under the law of the State of Delaware, indemnify and upon
     request shall advance expenses to any person who is or was a party or is
     threatened to be made a party to any threatened, pending or completed
     action, suit, proceeding or claim, whether civil, criminal, administrative
     or investigative, by reason of the fact that such person is or was or has
     agreed to be a director or officer of this Corporation or any of its direct
     or indirect subsidiaries or while such a director or officer is or was
     serving at the request of this Corporation as a director, officer, partner,
     trustee, employee or agent of any corporation, partnership, joint venture,
     trust or other enterprise, including service with respect to employee
     benefit plans, against expenses (including attorney's fees and expenses),
     judgments, fines, penalties and amounts paid in settlement incurred in
     connection with the investigation, preparation to defend or defense of such
     action, suit, proceeding or claim; provided, however, that the foregoing
     shall not require this Corporation to indemnify or advance expenses to any
     person in connection with any action, suit, proceeding, claim or
     counterclaim initiated by or on behalf of such person. Such indemnification
     shall not be exclusive of other indemnification rights arising under any
     bylaws, agreement, vote of directors or stockholders or otherwise and shall
     inure to the benefit of the heirs and legal representatives of such person.
     Any person seeking
 
                                      II-3
<PAGE>   24
 
     indemnification under this Article shall be deemed to have met the standard
     of conduct required for such indemnification unless the contrary shall be
     established.
 
     The Bylaws of the registrant include indemnification provisions that
generally provide indemnification to directors and officers of the registrant in
the manner and to the extent permitted by Section 145 of the Delaware General
Corporation Law. However, the provisions corresponding to subsections 145(a) and
(b) are mandatory rather than permissive.
 
     The registrant has entered into Indemnification Agreements with each of its
directors and executive officers. Such Indemnification Agreements provide that
such persons (the "Indemnitees") will be indemnified and held harmless from all
expenses, including (without limitation) reasonable fees and expenses of
counsel, and all liabilities, including (without limitation) the amount of any
judgments, fines, penalties, excise taxes and amounts paid in settlement,
actually incurred by an Indemnitee with respect to any threatened, pending or
completed claim, action (including any action by or in the right of the
registrant), suit or proceeding (whether formal or informal, or civil, criminal,
administrative, legislative, arbitrative or investigative) in respect of which
such Indemnitee is, was or at any time becomes, or is threatened to be made, a
party, witness, subject or target, by reason of the fact that such Indemnitee is
or was a director, officer, agent or fiduciary of the registrant or serving at
the request of the registrant as a director, officer, employee, fiduciary or
representative of another enterprise. Such Indemnification Agreements also
provide that the registrant, if requested to do so by an Indemnitee, will
advance to such Indemnitee, prior to final disposition of any proceeding, the
expenses actually incurred by the Indemnitee subject to the obligation of the
Indemnitee to refund if it is ultimately determined that such Indemnitee was not
entitled to indemnification.
 
     The Company has a directors and officers reimbursement and liability
insurance policy that insures the Company's directors and officers against
certain liabilities.
 
     The Standby Agreement filed as Exhibit 1.1 to this Registration Statement
provides for indemnification and contribution by the Purchaser with respect to
certain liabilities of the registrant, its directors, officers, and other
controlling persons, including liabilities under the Securities Act of 1933.

ITEM 17. UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes:
 
          (1)     To file, during any period in which offers or sales are being
        made, a post-effective amendment to this registration statement.
 
             (i)  To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
        Provided, however, that paragraph (a)(1)(i) and (a)(1)(ii) shall not
        apply if the information required to be included in a post-effective
        amendment by those paragraphs is contained in periodic reports filed by
        the registrant pursuant to Section 13 or Section 15(d) of the Securities
        Exchange Act of 1934 that are incorporated by reference in the
        registration statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (e) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference and furnished pursuant to and meeting the requirements of Rule 14a-3
or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim
financial information required to be presented by Article 3 of Regulation S-X is
not set forth in the prospectus, to deliver, or cause to be delivered to each
person to whom the prospectus is sent or given, the latest quarterly report that
is specifically incorporated by reference in the prospectus to provide such
interim financial information.
 
     (h) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim or
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been
 
                                      II-5
<PAGE>   26
 
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this registration
statement or amendment thereto to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Dallas, State of Texas on October 31,
1995.

Sanders Morris Mundy Inc.
3100 Texas Commerce Tower
Houston, Texas 77002

Dear Sirs:

         USA Waste Services, Inc., a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to redeem on
December 11, 1995 (the "Redemption Date") all of its outstanding 8-1/2%
Convertible Subordinated Debentures due 2002 (the "Securities"), which are
convertible into shares (the "Conversion Shares") of Common Stock, par value
$.01 per share (the "Common Stock"), of the Company, at a redemption price of
105.67% of the principal amount of Securities plus accrued interest thereon
from Ocotber 15, 1995, to the Redemption Date (the "Redemption Price").  The
right to convert such Securities into Common Stock will expire at the close of
business on December 1, 1995 (the "Expiration Date").

         The Company desires to make arrangements pursuant to which the Company
will have the option to sell directly to Sanders Morris Mundy Inc. (the
"Purchaser") such number of shares of Common Stock (the "Redemption Shares")
equal to the number of shares of Common Stock that would have been issuable
upon conversion of the Securities that are not surrendered for conversion on or
prior to the close of business on the Expiration Date.

         1. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, the Purchaser that:
<PAGE>   2
         (a) A registration statement in respect of the Redemption Shares has
been filed with the Securities and Exchange Commission (the "Commission"); no
other document with respect to such registration statement or document
incorporated by reference therein has heretofore been filed or transmitted for
filing with the Commission; the various parts of such registration statement,
including all exhibits thereto, and including the documents incorporated by
reference in the prospectus contained in the registration statement at the time
such registration statement became or becomes effective, each as amended at the
time such registration statement became or becomes effective, being hereinafter
called the "Registration Statement"; and the prospectus on file with the
Commission at the time the Registration Statement became or becomes effective
being hereinafter called the "Prospectus;" and any reference herein to the
Prospectus shall be deemed to refer to and include the documents incorporated
by reference therein pursuant to Item 12 of Form S-3 under the Securities Act
of 1933, as amended (the "Act"); any reference to any amendment or supplement
to the Prospectus shall be deemed to refer to and include any documents filed
after the date of such Prospectus, under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), and incorporated by reference in such
Prospectus; and any reference to any amendment to the Registration Statement
shall be deemed to refer to and include any annual report of the Company filed
pursuant to Section 13(a) or 15(d) of the Exchange Act after the effective date
of the Registration Statement that is incorporated by reference in the
Registration Statement;

         (b) The documents incorporated by reference in the Prospectus, when
they were filed with the Commission, conformed in all material respects to the
requirements of the Act or the Exchange Act, as applicable, and the rules and
regulations of the Commission thereunder, and none of such documents at such
filing date contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and any further documents so filed and
incorporated by reference in the Prospectus or any further amendment or
supplement thereto, when such documents become effective or are filed with the
Commission, as the case may be, will conform in all material respects to the
requirements of the Act or the Exchange Act, as applicable, and the rules and
regulations of the Commission thereunder and will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that this representation and warranty shall not apply to any
statements or omissions made in reliance upon and in conformity with
information furnished in writing to the Company by the Purchaser expressly for
use therein;

         (c) The Registration Statement conforms, and the Prospectus and any
further amendments or supplements to the Registration Statement or the
Prospectus did or will, at the time of effectiveness or filing with the
Commission, as the case may be, conform, in all material respects to the
requirements of the Act and the rules and regulations of the Commission
thereunder and do not and will not, as of the applicable effective date as to
the Registration Statement and any amendment thereto and as of the applicable
filing date as to the Prospectus and any amendment or supplement thereto,
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; provided, however, that this representation and warranty shall not
apply to any





                                       2
<PAGE>   3
statements or omissions made in reliance upon and in conformity with
information furnished in writing to the Company by the Purchaser expressly for
use therein;

         (d) Neither the Company nor any of its subsidiaries has sustained
since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus any material loss or interference
with its businesses from fire, explosion, flood, or other calamity, whether or
not covered by insurance, or from any material labor dispute or court or
governmental action, order, or decree, otherwise than as set forth or
contemplated in the Prospectus; and, since the respective dates as of which
information is given in the Registration Statement and the Prospectus, there
has not been any material change in the capital stock or long-term debt of the
Company or any of its subsidiaries or any material adverse change, or any
development involving a prospective material adverse change, in or affecting
the general affairs, management, financial position, stockholders' equity, or
results of operations of the Company and its subsidiaries, otherwise than as
set forth or contemplated in the Prospectus;

         (e) The Company and its subsidiaries have good and marketable title in
fee simple to all real property and good and marketable title to all personal
property owned by them, in each case free and clear of all liens, encumbrances
and defects except such as are described in the Prospectus or such as do not
materially affect the value of such property and do not materially interfere
with the use made and proposed to be made of such property by the Company and

immediately available funds, payable by wire transfer to an account designated
by the Purchaser, an amount equal to the product of (i) $.40 and (ii) the
aggregate number of Redemption Shares purchased by the Purchaser. Such
additional compensation shall not be payable if the Purchaser determines not to
purchase the Conversion Shares on the Closing Date as a result of a failure to

extent related to Section 4(e), Section 4(i).

         (d) The Purchaser agrees to remit to the Company an amount equal to

price for the Redemption Shares set forth in Section 2(a) hereunder if the
number of Redemption Shares purchased by the Purchaser is equal to or less than
369,811 and (ii) not less than 50% of the excess, if any, of (A) the total
proceeds received on the sale of the Redemption Shares, less any selling

over (B) the purchase price for the Redemption Shares set forth in Section 2(a)
hereunder if the number of Redemption Shares purchased by the Purchaser is
greater than 369,811.  On completion of the sale of all of the Redemption
Shares, the Purchaser will furnish the Company a statement setting forth the
total proceeds received on the sale of the Redemption Shares and the applicable
selling concessions, transfer taxes and other direct, out-of-pocket selling
expenses, including fees and disbursements of counsel. Payment of any amount
due under this paragraph will be made by the Purchaser on the second business
day following the sale by the Purchaser of all the Redemption Shares. For
purposes of the foregoing determination, any Redemption Shares not sold by or
for the account of the Purchaser before the close of business on the 20th
business day after the Time of Delivery will be deemed to have been sold on
such 20th business day for an amount equal to the last reported sale price of
the Common Stock on such day as reported by the New York Stock Exchange.
Nothing herein shall limit the right of the Purchaser, in its discretion, to
determine the price or prices at which, and the time or times when, and
Redemption Shares will be sold, whether or not prior to the Redemption Date and

         (e)  Until the close of business on the Expiration Date, the Purchaser

so purchased will be converted into shares of Common Stock.  The shares of
Common Stock acquired by the Purchaser pursuant to the provisions of this
Section may be sold at any time or from time to time by the Purchaser.  It is
also understood that, for the purpose of stabilizing the price of the Common
Stock or otherwise, the Purchaser may, but is not obligated to, purchase and
sell shares of Common Stock or other securities of the Company and over-allot
in effecting sales of Common Stock, all in such amounts and at such prices as
the Purchaser may deem advisable.

                 compliance with the terms of the Indenture and the Securities;

                          (ix) The redemption of the Securities, the issuance
                 and sale of the Conversion Shares upon conversion of the
                 Securities or the Redemption Shares upon the sale by the
                 Company to the Purchaser as herein provided, the compliance by
                 the Company with all of the provisions of this Agreement and
                 the consummation of the transactions herein contemplated, to
                 the best of such counsel's knowledge, will not conflict with
                 or result in a breach or violation of any of the terms or
                 provisions of, or constitute a default under, any indenture,
                 mortgage, deed of trust, loan agreement or other agreement or
                 instrument to which the Company or any of its subsidiaries is
                 a party or by which the Company or any of its subsidiaries is
                 bound or to which any of the property or assets of the Company
                 or any of its subsidiaries is subject; nor will such actions
                 result in any violation of the provisions of the Certificate
                 of Incorporation, as amended, or the Bylaws of the Company or
                 any statute of the United States of America or of Delaware or
                 any other statute known to such counsel or any order, rule or

                 jurisdiction over the Company or any of its subsidiaries or
                 any of their properties;

                          (x) To the best of such counsel's knowledge, no
                 consent, approval, authorization, order, registration or
                 qualification of or with any such court or governmental agency
                 or body is required by or on behalf of the Company for the

                 redemption of the Securities, the issuance of the Conversion   
                 Shares upon conversion of the Securities or the Redemption
                 Shares upon the sale by the Company to the Purchaser as herein 
                 provided or the consummation by the Company of the other 
                 transactions contemplated by this Agreement, except such as 
                 have been obtained under the Act, the listing of the
                 Redemption Shares on the NYSE, which will occur prior to the
                 Time of Delivery, and such consents, approvals,
                 authorizations, registrations or qualifications as may be
                 required under state securities or Blue Sky laws in connection
                 with the purchase and distribution of the Redemption Shares by
                 the Purchaser;
        
                          (xi) The documents incorporated by reference in the
                 Prospectus or any further amendment or supplement thereto made
                 by the Company prior to the Time of Delivery (other than (a)
                 the financial statements, notes and schedules thereto included
                 or incorporated by reference therein and (b) other financial
                 and statistical information included or incorporated by
                 reference therein, as to all of which such counsel need
                 express no opinion), when they became effective or were filed
                 with the Commission, as the case may be, complied as to form
                 in all material respects with the requirements of the Act or
                 the Exchange Act, as applicable, and the rules and regulations
                 of the Commission thereunder; and such counsel has no reason
                 to believe that any of such documents, when such documents
                 became effective or were so filed, as the case may be,
                 contained, in the case of a registration statement which
                 became effective under the Act, an untrue statement of a
                 material fact, or omitted to state a material fact required to
                 be stated therein or necessary to make the statements therein
                 not misleading, or, in the case of other documents which were
                 filed under the Act or the Exchange Act with the Commission,
                 an untrue statement of a material fact or omitted to state a
                 material fact necessary in order to make the statements
                 therein, in the light of the circumstances under which they
                 were made when such documents were so filed, not misleading;

                          (xii) The Registration Statement and the Prospectus
                 and any further amendments and supplements thereto made by the
                 Company prior to the Time of Delivery (other than (a) the
                 financial statements, notes and schedules thereto included or
                 incorporated by reference therein and (b) other financial and
                 statistical information included or incorporated by reference
                 therein, as to all of which such counsel need express no
                 opinion) comply as to form in all material respects with the
                 requirements of the Act and the rules and regulations
                 thereunder; such counsel has no reason to believe that, as of
                 its effective date, the Registration Statement or any further
                 amendment thereto made by the Company prior to the Time of
                 Delivery (other than (a) the financial statements, notes and
                 schedules thereto included or incorporated by reference
                 therein and (b) other financial and statistical information
                 included or incorporated by reference therein, as to all of
                 which such counsel need express no opinion) contained an
                 untrue statement of a material fact or omitted to state a
                 material fact required to be stated therein or necessary to
                 make the statements therein not misleading or that, as of its
                 date, the Prospectus





                                       12

         or any further amendment or supplement thereto made by the Company
         prior to the Time of Delivery (other than (a) the financial
         statements, notes and schedules thereto included or incorporated by
         reference therein and (b) other financial or statistical information
         included or incorporated by reference therein, as to all of which such
         counsel need express no opinion) contained an untrue statement of a
         material fact or omitted to state a material fact necessary to make
         the statements therein, in light of the circumstances in which they
         were made, not misleading or that, as of the Time of Delivery, either
         the Registration Statement or the Prospectus or any further amendment
         or supplement thereto made by the Company prior to the Time of
         Delivery (other than (a) the financial statements, notes and schedules
         thereto included or incorporated by reference therein and (b) other
         financial or statistical information included or incorporated by
         reference therein, as to all of which such counsel need express no
         opinion) contains an untrue statement of a material fact or omits to
         state a material fact necessary to make the statements therein, in
         light of the circumstances in which they were made, not misleading;
         and such counsel does not know of any amendment to the Registration
         Statement required to be filed or of any contracts or other documents
         of a character required to be filed as an exhibit to the Registration
         Statement or required to be incorporated by reference into the
         Prospectus or required to be described in the Registration Statement
         or the Prospectus which are not filed or incorporated by reference or
         described as required;

         (d) At the Time of Delivery, the Purchaser shall have received a
letter or letters, in form and substance satisfactory to the Purchaser, from
Coopers & Lybrand L.L.P. with respect to the financial statements and certain
financial information contained in the Registration Statement and the
Prospectus and from Deloitte & Touche L.L.P. and Arthur Andersen L.L.P. each
with respect to the financial statements and certain financial information
contained in the Registration Statement and the Prospectus;

         (e) (i) Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus any loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered
by insurance, or from any labor dispute or court or governmental action, order
or decree, otherwise than as set forth or contemplated in the Prospectus, and
(ii) since the respective dates as of which information is given in the
Prospectus there shall not have been any change in the capital stock or
long-term debt of the Company or any of its subsidiaries or any change, or any
development involving a prospective change, in or affecting the general
affairs, management, financial position, stockholders' equity or results of
operations of the Company and its subsidiaries, otherwise than as set forth or
contemplated in the Prospectus, the effect of which, in any such case described
in clause (i) or (ii), is in the Purchaser's reasonable judgment so material
and adverse as to make it impracticable or inadvisable to proceed with the
transactions contemplated by this Agreement on the terms and in the manner
contemplated in the Prospectus;





                                       13
<PAGE>   14
         (f) On or after the date hereof there shall not have occurred any of
the following: (i) a suspension or material limitation in trading in securities
generally on the NYSE; (ii) a general moratorium on commercial banking
activities in Texas declared by either Federal or Texas State authorities; or
(iii) the outbreak or escalation of hostilities involving the United States or
the declaration by the United States of a national emergency or war, if the
effect of any such event specified in this clause (iii) in the Purchaser's
reasonable judgment makes it impracticable or inadvisable to proceed with the
transactions contemplated by this Agreement on the terms and in the manner
contemplated by the Prospectus;

         (h) The Conversion Shares are listed, and the Redemption Shares to be
sold by the Company at the Time of Delivery shall have been duly listed,
subject to notice of issuance, on the NYSE; and

         (i) The Company shall have furnished or caused to be furnished to the
Purchaser on the Effective Date and at Time of Delivery certificates of
officers of the Company satisfactory to the Purchaser as to the accuracy of the
representations and warranties of the Company herein at and as of the Effective
Date or the Time of Delivery (other than, in the case of the Time of Delivery,
Section 1(d)), respectively, as to the performance by the Company of all of its
obligations hereunder to be performed at or prior to the Effective Date or the
Time of Delivery, as the case may be, as to the matters set forth in
subsections (a) and (e) of this Section and as to such other matters as the
Purchaser may reasonably request.

         5. Indemnification.  (a) The Company will indemnify and hold harmless
the Purchaser against any losses, claims, damages or liabilities, to which the
Purchaser may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse the Purchaser for any legal or other expenses reasonably incurred by
the Purchaser in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that the Company shall
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in the Registration
Statement or the Prospectus or any such amendment or supplement in reliance
upon and in conformity with written information furnished to the Company by the
Purchaser expressly for use therein.

         (b) The Purchaser will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein not





                                       14
<PAGE>   15
misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission
was made in the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by the Purchaser expressly for use therein; and will
reimburse the Company for any legal or other expenses reasonably incurred by
the Company in connection with investigating or defending any such action or
claim as such expenses are incurred.

         (c) Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection.  In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under such subsection for any legal expenses of other counsel or any
other expenses, in each case subsequently incurred by such indemnified party,
in connection with the defense thereof other than reasonable costs of
investigation;

         (d) If the indemnification provided for in this Section 5 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and the Purchaser
on the other from the transactions contemplated by this Agreement.  If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (c) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company on the one hand and the Purchaser on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations.  The relative benefits received
by the Company on the one hand and the Purchaser on the other with respect to
the transactions contemplated by this Agreement shall be deemed to be in the
same proportion as the market value of the Common Stock issuable upon
conversion of the Securities on the last Trading Day (as defined in Section
6(b)) immediately preceding the date of this Agreement (calculated based on the
Closing Price of the Common Stock) bears to the compensation received by the
Purchaser pursuant to Section 2.  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement





                                       15
<PAGE>   16
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the Purchaser
on the other and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.  The Company
and the Purchaser agree that it would not be just and equitable if
contributions pursuant to this subsection (d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this subsection (d).  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to
above in this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (d), the Purchaser shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Redemption Shares purchased by it and distributed to the public were
offered to the public exceeds the amount of any damages which the Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.
         (e) The obligations of the Company under this Section 5 shall be in
addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who
controls the Purchaser within the meaning of the Act; and the obligations of
the Purchaser under this Section 5 shall be in addition to any liability which
the Purchaser may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company within the meaning of the Act.

         6. Miscellaneous.  (a) The respective indemnities, agreements,
representations, warranties and other statements of the Company and the
Purchaser as set forth in this Agreement or made by them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless
of any investigation (or any statement as to the results thereof) made by or on
behalf of the Purchaser or any controlling person of the Purchaser or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of the Conversion Shares and the Redemption Shares and
payment for the Redemption Shares.

         (b)  For purposes of this Agreement, "Trading Day" means a day on
which the Common Stock is traded on the NYSE, and "Closing Price" means the
reported last sale price regular way per share of the Common Stock, or in case
no such reported sale takes place on such day, the average of the reported
closing bid and asked prices regular way, in either case on the NYSE.

         (c)  If for any reason after the notice pursuant to Section 2(a) has
been delivered, No Redemption Shares included in such notice are delivered by
or on behalf of the Company as provided herein, the Company will reimburse the
Purchaser for all out-of-pocket expenses, including fees and disbursements of
counsel, reasonably incurred by the Purchaser in making preparations for the
purchase, sale and delivery of the Redemption Shares not so delivered, but





                                       16
<PAGE>   17
the Company shall then be under no further liability to the Purchasers in
respect of the Redemption Shares not so delivered except as provided in Section
2 and Section 5 hereof.

         (d)  All statements, requests, notices and agreements hereunder shall
be in writing, and if to the Purchaser shall be delivered or sent by mail,
telex or facsimile transmission to Sanders Morris Mundy Inc., 3100 Texas
Commerce Tower, Houston, Texas 77002, Attention: Ben T. Morris, facsimile
number 713-224-1101; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: General Counsel, facsimile number
214-383-7911.  Any such statements, requests, notices or agreements shall take
effect at the time of receipt thereof.

         (e)  This Agreement shall be binding upon, and inure solely to the
benefit of, the Purchaser, the Company and, to the extent provided in Section 5
and Section 6(a) hereof, the officers and directors of the Company and each
person who controls the Company or the Purchaser, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement.  No purchaser
of any of the Redemption Shares from the Purchaser shall be deemed a successor
or assign by reason merely of such purchase.

         (f)  Time shall be of the essence of this Agreement.  As used herein,
the term "business day" shall mean any day when the Commission's office in
Washington, D.C.  is open for business.

         (g)  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS.

         (h)  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us five counterparts hereof, and upon the acceptance hereof by
the Purchaser this letter and such acceptance hereof shall constitute a binding
agreement between the Purchaser and the Company.

                                                  Very truly yours,

USA Waste Services, Inc.
5400 LBJ Freeway
Suite 300, Tower One
Dallas, Texas  75240

Gentlemen:

         We have acted as counsel for USA Waste Services, Inc., a Delaware
corporation (the "Company"), in connection with the filing of the Registration
Statement on Form S-3 with respect to the registration of 3,172,226 shares (the
"Shares") of the Common Stock, $.01 par value (the "Common Stock"), of the
Company issuable to Sanders Morris Mundy Inc.  under certain standby
arrangements in connection with the conversion of the Company's 8-1/2%
Convertible Subordinated Debenture Due 2002 (the "Debentures").

         We have made such inquiries and examined such documents as we have
considered necessary or appropriate for purposes of giving the opinions
hereinafter set forth, including the examination of executed or conformed
counterparts, or copies certified or otherwise proved to our satisfaction, of
the following:

         (a)     the Restated Certificate of Incorporation of the Company as
filed with the Secretary of State of Delaware on June 30, 1995;

         (b)     the By-laws of the Company;

         (c)     the Registration Statement on Form S-3 of the Company,
including the related prospectus and other attachments, filed with the
Securities and Exchange Commission to register the Shares under the Securities
Act of 1933 (the "Registration Statement").

                              NOTICE OF REDEMPTION
 
              8 1/2% CONVERTIBLE SUBORDINATED DEBENTURES DUE 2002
 
        CONVERSION PRIVILEGE EXPIRES AT 5:00 P.M. (EASTERN TIME) AT THE
                    PLACE OF CONVERSION ON DECEMBER 1, 1995
 
     NOTICE IS HEREBY GIVEN that, at 5:00 p.m. on December 11, 1995 (the
"Redemption Date"), pursuant to Section 1205 of the Indenture dated as of
September 1, 1992 (the "Indenture"), between USA Waste Services, Inc. (the
"Company") and State Street Bank and Trust Company as successor to The First
National Bank of Boston, as Trustee, the Company will redeem all of its
outstanding 8- 1/2% Convertible Subordinated Debentures Due 2002 (the
"Debentures"), at a redemption price of $1,056.67 plus accrued interest of
$13.46 from October 15, 1995, to the Redemption Date, for a total of $1,070.16
for each $1,000 principal amount of Debentures (the "Redemption Price"). The
Redemption Price will be due and payable on each $1,000 principal amount of
Debentures on the Redemption Date (unless the Debentures are converted as
referred to below). From and after the Redemption Date, interest thereon shall
cease to accrue, and holders of Debentures will not have any rights as such
holders other than the right to receive the Redemption Price, without interest,
upon surrender of their Debentures.
 
                ALTERNATIVES AVAILABLE TO HOLDERS OF DEBENTURES
 
HOLDERS OF DEBENTURES HAVE THE FOLLOWING ALTERNATIVES:
 
     1. Conversion. Prior to 5:00 p.m. (Eastern time) on December 1, 1995, to
convert any or all of the Debentures into the Company's Common Stock at a
conversion price of $13.25 per share (75.472 shares of Common Stock for each
$1,000 principal amount of Debentures). Holder's will receive a cash payment in
lieu of any fractional share. The method of delivery is at the option and risk
of the holder but, if mail is used, it is recommended that registered mail with
return receipt requested, properly insured, be used as a prevention against
loss. If conversion is being requested, Debenture certificates should be mailed,
together with a Letter of Transmittal, sufficiently in advance of December 1,
1995, to permit delivery to the Trustee on or before such date and time.
 
     2. Redemption. To surrender Debentures for redemption at the total
Redemption Price of $1,070.16 for each $1,000 principal amount of Debentures.
 
     3. Sale Through Ordinary Brokerage Transactions. To sell the Debentures
through open market brokerage transactions and, if made sufficiently in advance
of December 1, 1995, buyers thereof may convert the Debentures into Common Stock
in the manner described herein. After December 1, 1995, a holder of Debentures
will not be entitled to convert such Debentures into Common Stock. This is
expected to have an impact on the market for the Debentures. Holders of
Debentures who wish to make sales should consult with their brokers concerning
if and when such Debentures should be sold.
 
     Instructions on presentation of Debentures for conversion or redemption are
given on the accompanying Letter of Transmittal.

     In order to be converted into Common Stock, the Debentures must be
presented, surrendered and received before 5:00 p.m. (Eastern time) on December
1, 1995, to State Street Bank and Trust Company at one of the following
addresses, where they may also be surrendered for redemption:

         State Bank and Trust Company                         Chemical Bank
    Corporate Trust Department, 4th Floor           A/C State Street Bank & Trust Co.

</TABLE>
 
     For the convenience of holders of Debentures, a form of Letter of
Transmittal, which may be used for forwarding Debentures for conversion or for
redemption by the Company, has been mailed to each record holder of Debentures
and to nominees for holders of Debentures to be forwarded to each holder with a
copy of this notice, together with a copy of a Prospectus relating to Common
Stock issuable by the Company to Sanders Morris Mundy Inc., as standby purchaser
in respect of Debentures not converted by the holders thereof into shares of
Common Stock on or before December 1, 1995. Additional copies of the form of
Letter of Transmittal and the Prospectus may be obtained from the Company, 5400
LBJ Freeway, Suite 300 -- Tower One, Dallas, Texas 75240, Attn: Ms. Kay
Stockler, (214) 383-7900.
 
     THE LAST REPORTED SALE PRICE OF THE COMMON STOCK ON OCTOBER 30, 1995, WAS
$20.75 PER SHARE. AT SUCH LAST REPORTED SALE PRICE PER SHARE, THE HOLDER OF
$1,000 PRINCIPAL AMOUNT OF DEBENTURES WOULD RECEIVE, UPON CONVERSION, 75 SHARES
OF COMMON STOCK AND CASH IN LIEU OF A FRACTIONAL SHARE HAVING AN AGGREGATE
MARKET VALUE OF APPROXIMATELY $1,566.03. SUCH VALUE IS SUBJECT TO CHANGE
DEPENDING ON CHANGES IN THE MARKET PRICE OF THE COMMON STOCK. SO LONG AS THE
MARKET PRICE OF THE COMMON STOCK IS AT LEAST $14.18 PER SHARE, HOLDERS OF
DEBENTURES WHO CONVERT THEIR DEBENTURES INTO COMMON STOCK WILL RECEIVE COMMON
STOCK HAVING A GREATER MARKET VALUE (WITHOUT TAKING INTO CONSIDERATION SALES
EXPENSE) THAN THE CASH WHICH THEY WOULD RECEIVE UPON REDEMPTION.
 
     Please be sure to read and follow the instructions on the Letter of
Transmittal.
 
     If there are any questions concerning this matter, please contact either
