  The information contained in this Prospectus Supplement is qualified in its
entirety by the more detailed information appearing in the accompanying
Prospectus and the documents incorporated by reference therein. Unless
otherwise indicated, all information contained in this Prospectus Supplement
(i) assumes that the Underwriters' overallotment option is not exercised and
(ii) has been adjusted to give effect to a 2-for-1 stock split effected on June
18, 1996. Unless otherwise indicated, the terms "the Company" and "United Waste
Systems" refer collectively to United Waste Systems, Inc. and its subsidiaries.
 
                                  THE COMPANY
 
  United Waste Systems provides integrated solid waste management services to
commercial, industrial and residential customers in 20 states. These services
include nonhazardous landfill operations, waste collection services, waste
reuse and reduction programs (such as composting and recycling) and related
environmental services. The Company has completed approximately 170
acquisitions of solid waste businesses since its formation in July 1989,
including over 85 completed since January 1, 1996.
 
  The Company currently operates 35 nonhazardous landfill operations (including
14 that it operates on behalf of municipalities), 59 waste collection companies
that have over 2,600 collection vehicles and trailers and serve over 850,000
customers, and 66 waste transfer stations (including seven that it operates on
behalf of municipalities). The Company also owns and operates several
facilities utilized in connection with providing waste reuse and reduction
programs.
 
  The Company generally targets regions in which it has the potential to
establish a significant position and benefit from economies of scale. The
Company believes that this potential is greatest in regions where there are
few, if any, well capitalized and established waste management companies
present and where demand for integrated waste management services is expected
to increase. The Company has succeeded in establishing and maintaining a
significant position in a majority of the geographic regions in which it
currently operates.
 
  The Company's objective is to continue to expand through a combination of new
acquisitions and internal growth. The focus of the Company's acquisition
program at present is to capitalize on opportunities around its existing
operating regions that will create synergies and efficiencies, as well as to
selectively enter several new regions annually. The Company may also
selectively consider acquisition or consolidation opportunities involving other
public companies or large privately-held companies. The Company's strategy for
improving internal growth is to consolidate and integrate operations, improve
operating efficiencies, provide high levels of customer service, market to new
customers and maintain strict cost controls.
 
  United Waste Systems, Inc. was incorporated in the State of Delaware in 1989.
Its executive offices are located at Four Greenwich Office Park, Greenwich,
Connecticut 06830, and its telephone number is (203) 622-3131.

                              RECENT DEVELOPMENTS
 
ACQUISITIONS COMPLETED SINCE OCTOBER 1, 1996
 
  From October 1, 1996 through February 12, 1997, the Company completed 36
acquisitions, including 21 "tuck-in" acquisitions. (A tuck-in acquisition is
one in which the Company acquires a collection company's vehicles and assumes
the service rights and obligations relating to such company's customers, which
are then fully integrated into one of the Company's existing collection
operations). In connection with these acquisitions (other than the tuck-in
acquisitions), the Company acquired: (i) four nonhazardous landfill operations
(all of which the Company operates on behalf of municipalities), (ii) 15
nonhazardous waste collection companies, and (iii) 10 transfer stations (three
of which the Company operates on behalf of municipalities). The landfill
operations are located in California (2), Colorado (1) and New Mexico (1). The
collection companies are located in Arizona (1), California (2), Colorado (3),
Kentucky (1), Maine (2), Massachusetts (1), Michigan (1), New Mexico (3) and
North Dakota (1). The transfer stations are located in California (2), Colorado
(4), Kentucky (1), Maine (1), Massachusetts (1) and Michigan (1).
 
LETTERS OF INTENT
 
  The Company has entered into 20 non-binding letters of intent relating to
possible acquisitions and is in discussions with a number of additional
potential acquisition candidates. In addition, the Company has an option to
purchase certain operations. These letters of intent and the option relate to
the possible acquisition by the Company of 19 nonhazardous solid waste
collection companies, two nonhazardous landfill operations and three transfer
stations. Based upon information provided to the Company in connection with its
preliminary investigation of these businesses, the Company estimates that the
aggregate annualized revenues of these businesses is approximately $70 million.
However, in view of the preliminary nature of this estimate, there can be no
assurance that actual revenues will not differ. Furthermore, in view of the
fact that these letters of intent are nonbinding and that the Company has not
completed its due diligence investigations with respect to these potential
acquisitions, the Company cannot predict whether these letters of intent will
lead to definitive agreements or whether the terms of any such definitive
agreements will be the same as the terms contemplated by the letters of intent.
 
AMENDMENT OF CREDIT FACILITY
 
  The Company's credit facility was amended in December 1996 to, among other
things, eliminate certain covenants and lower borrowing costs. The credit
facility as so amended (the "Credit Facility") provides for a $190 million,
three year, secured revolving credit facility due December 1999. Outstanding
loans under the Credit Facility bear interest at a rate per annum equal to the
Eurodollar Rate (Reserve Adjusted) (as defined in the loan agreement providing
for the Credit Facility) applicable to each interest period plus 0.625% to
1.25% per annum or the Alternate Reference Rate (as so defined) from time to
time in effect. The Credit Facility also allows the Company to obtain up to $90
million in letters of credit. The aggregate amount that the Company is
permitted to borrow under the Credit Facility is reduced by the aggregate face
amount of all outstanding letters of credit issued thereunder. The Credit
Facility is secured by the stock of the Company's subsidiaries, restricts the
Company from granting other liens on its assets (subject to certain limited
exceptions), and requires the Company to comply with certain covenants
including, but not limited to, maintenance of certain financial ratios,
limitations on additional indebtedness, limitations on capital expenditures and
a prohibition on the Company's payment of cash dividends on its Common Stock.
The Credit Facility also currently requires that the consent of the lenders be
obtained in order for the Company to make an acquisition that provides for an
aggregate cash purchase price of $50 million or more. In addition, the Credit
Facility prohibits the Company from using more than $15 million of its cash to
secure closure and post-closure obligations that the Company may have relating
to its landfills. At February 11, 1997, the aggregate outstanding indebtedness
under the Credit Facility amounted to $43.6 million.

(1) Certain of the companies that the Company acquired in transactions
    accounted for as pooling-of-interests were Subchapter S Corporations or
    partnerships prior to being acquired. In general, the income or loss of a
    Subchapter S Corporation or partnership is passed through to its owners
    rather than being subjected to taxes at the entity level. Pro forma net
    income reflects a provision for income taxes on a pro forma basis for all
    periods presented as if all such companies were liable for federal and
    state income taxes as taxable corporate entities for all periods presented.
(2) Reflects deductions for dividends on preferred stock and certain interest
    expense adjustments related to use of the treasury stock method of

    offering price of $36.75 per share (the last reported sale price of the

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus Supplement and
accompanying Prospectus, the following risk factors should be considered
carefully in evaluating the Company and its business before purchasing shares
of the Common Stock offered hereby. Information contained or incorporated by
reference in this Prospectus Supplement or the accompanying Prospectus
contains "forward-looking statements." There can be no assurance, however,
that the actual results will not differ materially from the Company's
expectations, statements or projections. Factors that could cause actual
results to differ from the Company's expectations, statements or projections
include the risks and uncertainties relating to the Company's business
described below.
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
  Although the Company performs an investigation of each business that it
acquires, there may nevertheless be liabilities that the Company fails or is
unable to discover, including liabilities arising from environmental
contamination, non-compliance by prior owners or operators with environmental
laws or regulatory requirements or poor management practices by prior owners
or operators, and for which the Company, as a successor owner or operator, may
be responsible. The Company seeks to minimize the impact of these liabilities
by obtaining indemnities and warranties from the seller which may be supported
by deferring payment of a portion of the purchase price. However, these
indemnities and warranties, if obtained, may not fully cover the liabilities
due to their limited scope, amount, or duration, the financial limitations of
the indemnitor or warrantor, or other reasons.
 
  As the Company completes acquisitions in a region, it seeks to achieve
synergies and efficiencies through the integration of newly acquired and
existing operations in the region. There can be no assurance, however, that
the Company will be successful in this regard or that such efforts may not in
certain circumstances adversely affect its existing operations.
 
EXTENSIVE ENVIRONMENTAL AND LAND USE LAWS AND REGULATIONS
 
  The Company is subject to extensive and evolving environmental and land use
laws and regulations, which are becoming increasingly stringent as a result of
greater public interest in protecting the environment. These laws and
regulations affect the Company's business in many ways, including as set forth
below.
 
  EXTENSIVE PERMITTING REQUIREMENTS. In order to develop and operate a
landfill or other solid waste management facility, it is necessary for the
Company to obtain and maintain in effect various facility permits and other
governmental approvals, including those related to zoning, environmental and
land use. The Company may also be required to obtain other or similar permits
and approvals to expand its existing landfill operations and other solid waste
management operations. These permits and approvals are difficult, time
consuming and costly to obtain, may be subject to community opposition,
opposition by various local elected officials or citizens, regulatory delays
and other uncertainties, and may be dependent upon the Company's facilities
being included in state or local solid waste management plans and the
Company's entering into satisfactory host agreements with local communities.
In addition, after an operating permit for a landfill or other facility is
obtained, the permit may be subject to modification, renewal or revocation by
the issuing agency, which may increase the Company's obligations and reopen
opportunities for opposition relating to the permit. Moreover, from time to
time, regulatory agencies may impose moratoria on, or otherwise delay, the
review or grant of these permits or approvals or they may modify the
procedures or increase the stringency of the standards applicable to such
review or the grant of such permits or approvals. For example, a Massachusetts
state regulatory agency imposed a moratorium in late 1995 on the review of
applications for landfill expansion and construction permits and has proposed
new, more stringent
 
                                      S-8
<PAGE>
 
criteria to govern such permit issuances after the moratorium is lifted. The
state regulatory agency has indicated that the moratorium may be lifted in
1998, although there can be no assurance of this. The Company is engaged in
discussions with the regulatory agency regarding the moratorium, which if
continued to be applied would delay regulatory review of the Company's permit
applications for new cell construction required at its Barre and Holyoke
landfills to replace the existing cells which might otherwise be exhausted in
1998. There can be no assurance that the Company will be successful in
obtaining and maintaining in effect the permits and approvals required for the
successful operation and growth of its business, including permits and
approvals required for the development of additional disposal capacity needed
to replace existing capacity that is exhausted. The failure by the Company to
obtain or maintain in effect a permit or agreement significant to its business
could adversely affect the Company's business and financial condition. See "--
Capitalized Expenditures."
 
  DESIGN, OPERATION AND CLOSURE REQUIREMENTS. The design, operation and
closure of landfills are subject to extensive regulations. These regulations
include, among others, the regulations (the "Subtitle D Regulations")
establishing minimum federal requirements adopted by the United States
Environmental Protection Agency (the "EPA") in October 1991 under Subtitle D
of the Resource Conservation and Recovery Act of 1976 ("RCRA"), which
regulations generally became effective on October 9, 1993 (except for new
financial assurance requirements, which are scheduled to become effective
April 9, 1997). The Subtitle D Regulations require all implementing states to
adopt regulations regarding landfill design, operation, closure and post-
closure that are as stringent as, or more stringent than, the Subtitle D
Regulations. All states in which the Company operates landfills have in place
extensive landfill regulations which have been updated or replaced with new
regulations at least as stringent as the Subtitle D requirements. These
federal and state regulations include, among other things, requirements that
the Company monitor groundwater, control leachate and air emissions, post
financial assurances, and fulfill landfill closure and post-closure
obligations. These regulations could also require the Company to undertake
investigatory or remedial activities, to curtail operations or to close a
landfill temporarily or permanently. Furthermore, future changes in these
regulations may require the Company to modify, supplement, or replace
equipment or facilities or increase the amount of financial guarantees at
costs which could be substantial.
 
  LEGAL AND ADMINISTRATIVE PROCEEDINGS. In the ordinary course of its
business, the Company may become involved in a variety of legal and
administrative proceedings relating to land use and environmental laws and
regulations. These may include proceedings by federal, state or local agencies
seeking to impose civil or criminal penalties on the Company for violations of
such laws and regulations, or to impose liability on the Company under RCRA,
Superfund (as discussed below) or comparable state statutes, or to revoke, or
deny renewal of, a permit; actions brought by citizens' groups, adjacent
landowners or governmental entities opposing the issuance of a permit or
approval to the Company or alleging violations of the permits pursuant to
which the Company operates or laws or regulations to which the Company is
subject; and actions seeking to impose liability on the Company for any
environmental damage at its owned or operated facilities (or at facilities
formerly owned by the Company or its predecessors) or damage that those
facilities or other properties may have caused to adjacent landowners or
others, including groundwater, soil or air contamination or personal injury.
These may arise out of the presence of hazardous substances in landfills,
methane or odor emissions or other conditions. The Company could incur
substantial legal expenses during the course of the aforementioned
proceedings, and the adverse outcome of one or more of these proceedings could
adversely affect the Company's business and financial condition.
 
  During the ordinary course of its operations, the Company has from time to
time received, and expects that it may in the future from time to time
receive, citations or notices from governmental authorities that its
operations are not in compliance with its permits or certain applicable
environmental or land use laws and regulations. The Company generally seeks to
work with the authorities to resolve the issues raised by such citations or
notices. There can be no assurance, however, that the Company
 
                                      S-9
<PAGE>
 
will always be successful in this regard, and the failure to resolve a
significant issue in a favorable manner could result in one or more of the
adverse consequences to the Company described below under "--Potential
Liabilities."
 
  POTENTIAL LIABILITIES. There may be various adverse consequences to the
Company in the event that a facility owned or operated by the Company (or by a
predecessor owner or operator whose liabilities the Company may have acquired
expressly or under successor or other liability theories) causes environmental
damage, in the event that waste transported by the Company (or a predecessor)
causes or threatens to cause environmental damage at another site, or in the
event that the Company (or a predecessor) fails to comply with applicable
environmental and land use laws and regulations or the terms of a permit or
outstanding administrative or consent order. These may include the imposition
of substantial monetary penalties on the Company; the issuance of orders
requiring the curtailment or termination of the operations involved or
affected; the revocation, denial or deferral of review of permits or other
approvals necessary for continued operation or landfill expansion; capacity
reductions or acceleration of closure requirements; the imposition of
liability on the Company in respect of any environmental damage (including
groundwater or soil contamination) at its facilities or that its landfills or
other Company owned or operated facilities caused to adjacent landowners or
others or to natural resources or environmental damage at another site
associated with waste transported by the Company; the imposition of liability
on the Company under Superfund or under comparable state laws; the imposition
of liability on the Company in personal injury lawsuits; and criminal
liability for the Company or its officers. Any of the foregoing could
adversely affect the Company's business and financial condition.
 
  The Comprehensive Environmental Response, Compensation, and Liability Act of
1980 ("Superfund") and analogous state laws impose retroactive strict joint
and several liability on certain parties that have owned, operated or sent
waste to a site from which there has been, or is threatened, a release of any
hazardous substance (as defined by Superfund) into the environment. Liability
under RCRA, Superfund and analogous state laws may include responsibility for
costs of site investigations, site cleanup, natural resources damages and
property damages. Liabilities under RCRA, Superfund and analogous state laws
can be very substantial and, if imposed upon the Company, could adversely
affect the Company's business and financial condition.
 
  In the ordinary course of its landfill and waste management and disposal
operations and in connection with its review of landfills and other operations
to be acquired, the Company has discovered, and may in the future discover,
indications of groundwater contamination at certain landfills. In such events,
the Company has sought or been required to determine the magnitude and source
of the problem and, if appropriate or required by applicable regulations, to
design and implement measures to monitor, remedy, and/or halt the spread of,
the contamination. There can be no assurance, however, that contamination
discovered at a landfill or other solid waste management facilities will not
result in one or more of the significant adverse consequences to the Company
described above.
 
  TYPE, QUANTITY AND SOURCE LIMITATIONS. Certain permits and approvals may
limit the types of waste that may be accepted at a landfill or the quantity of
waste that may be accepted at a landfill during a given time period. In
addition, certain permits and approvals, as well as certain state and local
regulations, may seek to limit a landfill to accepting waste that originates
from specified geographic areas or seek to restrict the importation of out-of-
state waste or otherwise discriminate against out-of-state waste. Generally,
such legislative or regulatory restrictions on the importation of out-of-state
waste have not to date withstood judicial challenge. However, from time to
time, federal legislation is proposed which would allow individual states to
prohibit the disposal of out-of-state waste or to limit the amount of out-of-
state waste that could be imported for disposal and would require states,
under certain circumstances, to reduce the amounts of waste exported to other
states. Although no such
 
                                     S-10
<PAGE>
 
federal legislation has to date been enacted, if such federal legislation
should be enacted in the future, states in which the Company operates
landfills could act to limit or prohibit the importation of out-of-state
waste. Such state actions could adversely affect the Company's landfills
within those states that receive a significant portion of waste originating
from other states.
 
  In addition, certain states and localities may for economic or other reasons
restrict the exportation of waste from their jurisdiction or require that a
specified amount of waste be disposed of at facilities within their
jurisdiction. In 1994, the United States Supreme Court held unconstitutional,
and therefore invalid, a local ordinance that sought to impose flow controls
on taking waste out of the locality. However, certain state and local
jurisdictions continue to seek to enforce such restrictions through
legislation or contractually and, in certain cases, the Company may elect not
to challenge such restrictions based upon various considerations. In addition,
the aforementioned federal legislation that has from time to time been
proposed could, if enacted, allow states and localities to impose certain flow
control restrictions. These restrictions could result in the volume of waste
going to landfills being reduced in certain areas, which may adversely affect
the Company's ability to operate its landfills at their full capacity and/or
reduce the prices that can be charged for landfill disposal services. These
restrictions may also result in higher disposal costs for the Company's
collection operations. If the Company were unable to pass such higher costs
through to its customers, the Company's results of operations could be
adversely affected.
 
LIMITS ON INSURANCE COVERAGE
 
  Subject to limited exceptions, the Company does not carry insurance for
environmental liability (other than insurance that is equivalent to self
insurance) because the Company believes that the cost for such insurance is
high relative to the coverage it would provide. Consequently, if the Company
were to incur liability for environmental damage, its business and financial
condition could be adversely affected. With the exception of insurance
coverage for environmental liability, the Company carries a broad range of
insurance for the protection of its assets and operations. However, the
Company's blanket insurance policy, which covers workers compensation,
automobile and general liability, is subject to a deductible of $250,000 per
incident.
 
ONGOING CAPITAL REQUIREMENTS
 
  To the extent that the proceeds from the Offering, internally generated cash
and cash available under the Company's Credit Facility are not sufficient to
provide the cash required for future operations, capital expenditures,
acquisitions, debt repayment obligations and/or financial assurance
obligations, the Company will require additional equity and/or debt financing
in order to provide such cash. There can be no assurance, however, that such
financing will be available or, if available, will be available on terms
satisfactory to the Company. The Company intends to pay for future
acquisitions using cash, capital stock, assumption of indebtedness and/or
notes, although there can be no assurance that the owners of the businesses
that the Company may wish to acquire will be willing to accept non-cash
consideration in whole or in part.
 
CAPITALIZED EXPENDITURES
 
  In accordance with generally accepted accounting principles, the Company
capitalizes certain expenditures and advances relating to its acquisitions,
pending acquisitions and landfill development and expansion projects. Indirect
acquisition costs, such as executive salaries, general corporate overhead,
public affairs and other corporate services, are expensed as incurred. The
Company's policy is to charge against earnings any unamortized capitalized
expenditures and advances (net of any portion thereof that the Company
estimates will be recoverable, through sale or otherwise) relating to any
operation that is permanently shut down, any pending acquisition that is not
consummated, and any landfill development or expansion project that is not
successfully completed. There can be no
 
                                     S-11
<PAGE>
 
assurance that the Company in future periods will not be required to incur a
charge against earnings in accordance with such policy, which charge,
depending upon the magnitude thereof, could adversely affect the Company's
results of operations.
 
AVAILABILITY OF ACQUISITION TARGETS
 
  The Company's ongoing acquisition program is a key element of its strategy
for expanding as an integrated provider of nonhazardous solid waste management
services. Consequently, the future growth of the Company depends in large part
upon the successful continuation of this program. The Company, however, in
some cases may encounter substantial competition in its efforts to acquire
landfills and collection operations and there can be no assurance that the
Company will succeed in locating appropriate acquisition candidates that can
be acquired at price levels that the Company considers appropriate.
 
COMMODITY RISK UPON RESALE OF RECYCLABLES
 
  A portion of the Company's revenues from waste reuse and reduction programs
is derived from the sale of recyclable waste products. The resale prices of,
and demand for, recyclable waste products can vary significantly and are
subject to changing market conditions. Accordingly, the Company's revenues
from such sales may materially vary from period to period.
 
ALTERNATIVES TO LANDFILL DISPOSAL
 
  Alternatives to landfill disposal, such as recycling and composting, are
increasingly being used. In addition, in certain of the Company's markets,
incineration is an alternative to landfill disposal. There also has been an
increasing trend at the state and local levels to mandate recycling and waste
reduction at the source and to prohibit the disposal of certain type of
wastes, such as yard wastes, at landfills. These developments may result in
the volume of waste going to landfills being reduced in certain areas, which
may affect the Company's ability to operate its landfills at their full
capacity and/or affect the prices that can be charged for landfill disposal
services.
 
FINANCIAL ASSURANCE OBLIGATIONS
 
  The Company is usually required to post a performance bond or a bank letter
of credit or to provide other forms of financial assurance in connection with
municipal residential collection contracts and the operation, closure and
post-closure of landfills. If the Company were unable to obtain surety bonds
or letters of credit in sufficient amounts or at reasonable rates, or to
provide other required forms of financial assurance, it might be precluded
from entering into additional municipal collection contracts or obtaining or
retaining required landfill permits and approvals.
 
COMPETITION
 
  The solid waste collection and disposal business is highly competitive and
requires substantial amounts of capital. The Company competes with numerous
waste management companies, a number of which have significantly larger
operations and greater resources than the Company. The Company also competes
with those counties and municipalities that maintain their own waste
collection and disposal operations. These counties and municipalities may have
financial advantages due to the availability to them of tax revenues and tax
exempt financing. In addition, competitors may reduce the price of their
services in an effort to expand market share or to win competitively bid
municipal contracts.
 
ECONOMIC CONDITIONS
 
  The Company's business is affected by general economic conditions. There can
be no assurance that an economic downturn will not result in a reduction in
the volume of waste being disposed of at the Company's operations and/or the
price that the Company can charge for its services.
 
                                     S-12
<PAGE>
 
WEATHER CONDITIONS
 
  Protracted periods of inclement weather may adversely affect the Company's
operations by interfering with collection and landfill operations, delaying
the development of landfill capacity and/or reducing the volume of waste
generated by the Company's customers. In addition, particularly harsh weather
conditions may result in the temporary suspension of certain of the Company's
operations.
 
SEASONALITY
 
  The Company's revenues tend to be somewhat lower in the winter months. This
is generally reflected in the Company's first quarter results and may also be
reflected in its fourth quarter results. This is primarily attributable to the
fact that (i) the volume of waste relating to construction and demolition
activities and activities relating to the remediation of contaminated soils
tends to increase in the spring and summer months and (ii) the volume of waste
relating to industrial and residential waste in the regions where the Company
operates tends to decrease during the winter months.
 
DEPENDENCE ON SENIOR MANAGEMENT
 
  The Company is highly dependent upon its senior management team. The loss of
the services of any member of senior management may have a material adverse
effect on the Company. The Company does not maintain "key man" life insurance
with respect to members of senior management.
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the Offering are estimated to be $104.3
million ($120.0 million if the Underwriters' over-allotment option is
exercised in full), based upon an assumed initial public offering price of
$36.75 per share (the last reported sale price of the Common Stock on February
11, 1997) and after deduction of the estimated underwriting discount and
offering expenses. The Company expects to use such net proceeds (i) to repay
approximately $43.6 million of outstanding indebtedness under the Company's
revolving Credit Facility and (ii) to fund acquisitions and for general
corporate purposes.
 
  At February 11, 1997, the outstanding amount of indebtedness under the
Credit Facility was $43.6 million and the weighted average interest rate on
such indebtedness was 6.19%. The proceeds from the outstanding indebtedness
under the Credit Facility were used primarily to fund acquisitions. See
"Recent Developments--Amendment of Credit Facility" for additional information
regarding the Credit Facility.

                                DIVIDEND POLICY
 
  No cash dividends have been paid to date by the Company on its Common Stock.
The Company intends to retain all earnings for the foreseeable future for use
in the operation and expansion of its business and, accordingly, the Company
currently has no plans to pay dividends on its Common Stock. The payment of
any future dividends will be determined by the Board of Directors in light of
conditions then existing, including the Company's earnings, financial
condition and requirements, restrictions in financing agreements, business
conditions and other factors. Under the terms of the Credit Facility, the
Company at present is prohibited from paying cash dividends on its Common
Stock. See "Recent Developments--Amendment of Credit Facility."

dealers at such price less a concession of $   per share. The Underwriters may
allow, and such dealers may reallow, a concession not in excess of $    per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and other selling terms

  The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus Supplement to purchase up to an aggregate of
450,000 additional shares of Common Stock solely to cover over-allotments, if
any. If the Underwriters exercise their over-allotment option, the
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
3,000,000 shares of Common Stock offered.
 
  The Company has agreed that, during the period beginning on the date of this
Prospectus Supplement and continuing to and including the 90th day after such
date, the Company will not, without the prior written consent of Goldman,
Sachs & Co., offer, sell, contract to sell or otherwise dispose of, or file
any registration statement (other than a registration statement relating to
securities that the Company may sell pursuant to clause (a), (b) or (c) below)
with respect to, any shares of Common Stock, any securities of the Company
substantially similar to the Common Stock, or any security exchangeable or
exercisable for or convertible into Common Stock or any such substantially
similar security (any such security, a "Covered Security"), other than (a)
pursuant to employee stock option plans existing as of the date hereof (as
such plans may hereafter be amended with stockholder approval) or in
connection with other employee incentive compensation arrangements consistent
with past practice, or upon the exercise of options heretofore or hereafter
granted pursuant to such plans or arrangements, (b) upon the conversion of
convertible securities or exercise of warrants or options, in each case as
outstanding on the date hereof, or (c) shares of Common Stock or other Covered
Securities issued as consideration for acquisitions of businesses, properties
or assets. Each director

and executive officer of the Company has agreed that he will not, directly or
indirectly, without the prior written consent of Goldman, Sachs & Co.,
publicly offer, sell, contract to sell or otherwise publicly dispose of (which
shall be deemed to include, without limitation, the entering into of any cash-
settled derivative instrument) any Covered Securities during the period
beginning on the date of this Prospectus Supplement and continuing to and
including the 90th day after such date.
 
  In connection with this offering, certain Underwriters and selling group
members (if any) or their respective affiliates who are qualifying registered
market makers on NASDAQ, may engage in passive market making transactions in
the Common Stock of the Company on NASDAQ in accordance with Rule 10b-6A under
the Securities Exchange Act of 1934 during the two business day period before
commencement of offers or sales of the Common Stock. The passive market
transactions must comply with applicable volume and price limits and be
identified as such. In general, a passive market maker may display its bid at
a price not in excess of the highest independent bid for the security; if all
independent bids are lowered below the passive market maker's bid, however,
such bid must then be lowered when certain purchase limits are exceeded.
 
  The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933.
 
  Goldman, Sachs & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated,
Deutsche Morgan Grenfell Inc., and certain other Underwriters have from time
to time provided, and may in the future provide, certain investment banking

the remarketing agent with respect to certain of the Company's tax-exempt
bonds.

  The validity of the Common Stock being sold in the Offering is being passed
upon for the Company by Ehrenreich & Krause, New York, New York, and for the
Underwriters by Sullivan & Cromwell, New York, New York. Certain legal matters
relating to environmental law will be passed upon for the Company by Proskauer

                        DESCRIPTION OF DEBT SECURITIES
 
  The Debt Securities constitute either Senior Securities or Subordinated
Securities. Debt Securities may be issued from time to time under one or more
indentures, each dated as of a date on or prior to the issuance of the Debt
Securities to which it relates. Senior Securities and Subordinated Securities
may be issued pursuant to separate indentures (respectively, a "Senior
Indenture" and a "Subordinated Indenture"), in each case between the Company
and a trustee, which may be the same trustee, and in the form that has been
filed as an exhibit to the Registration Statement of which this Prospectus is
a part, subject to such amendments or supplements as may be adopted form time
to time. Information regarding the trustee under the Senior Indenture (the
"Senior Trustee") and the trustee under the Subordinated Indenture (the
"Subordinated Trustee") will be included in any Prospectus Supplement relating
to such Debt Securities. The Senior Indenture and the Subordinated Indenture
are sometimes collectively referred to herein as the "Indentures;" and the
Senior Trustee and the Subordinated Trustee are sometimes collectively
referred to herein as the "Trustees" and individually as a "Trustee." The
following discussion includes a summary description of the anticipated terms
of the Indentures, other than terms which are specific to a particular series
of Debt Securities and which will be described in the Prospectus Supplement
relating to such series. However, if so indicated in a Prospectus Supplement,
the terms of the Indentures applicable to a particular series of Debt
Securities may differ from the terms set forth below. The following summaries
do not purport to be complete and are subject to, and are qualified in their
entirety by reference to, all of the provisions of the Indentures, including
the definitions therein of certain terms capitalized in this Prospectus.
Wherever particular Sections or Articles or defined terms of the Indentures
are referred to herein or in a Prospectus Supplement, such Sections or defined
terms are incorporated herein or therein by reference.
 
                                       4
<PAGE>
 
  The Debt Securities may be issued from time to time in one or more series.
The particular terms of each series of Debt Securities offered by any
Prospectus Supplement or Prospectus Supplements will be described in such
Prospectus Supplement or Prospectus Supplements relating to such series.
 
  Other than as may be indicated in the applicable Prospectus Supplement,
there are no provisions of the Indentures which afford holders of the Debt
Securities protection in the event of a highly leveraged transaction involving
the Company.
 
GENERAL
 
  The Indentures do not limit the aggregate amount of Debt Securities which
may be issued thereunder, and Debt Securities may be issued thereunder from
time to time in separate series up to the aggregate amount from time to time
authorized by the Company for each series. The Senior Securities will be
unsecured and unsubordinated obligations of the Company and will rank equally
and ratably with other unsecured and unsubordinated indebtedness of the
Company. The Subordinated Securities will be subordinated in right of payment
to the prior payment in full of the Senior Indebtedness (as defined) of the
Company, as described below under "--Subordination of Subordinated Securities"
and in a Prospectus Supplement applicable to an offering of Subordinated
Securities.
 
  The applicable Prospectus Supplement or Prospectus Supplements will describe
the following terms of the series of Debt Securities in respect of which this
Prospectus is being delivered: (1) the title of such Debt Securities; (2) any
limit on the aggregate principal amount of such Debt Securities; (3) whether
any of such Debt Securities are to be issuable in permanent global form
("Global Security") and, if so, the terms and conditions, if any, upon which
interests in such Debt Securities in global form may be exchanged, in whole or
in part, for the individual Debt Securities represented thereby; (4) the
person to whom any interest on any Debt Security of the series shall be
payable if other than the person in whose name the Debt Security is registered
on the Regular Record Date; (5) the date or dates on which such Debt
Securities will mature; (6) the rate or rates of interest, if any, or the
method of calculation thereof, which such Debt Securities will bear and, if
interest will not be payable in cash, the terms of any securities of the
Company to be issued in payment of interest; (7) the date or dates from which
any such interest will accrue, the Interest Payment Dates on which any such
interest on such Debt Securities will be payable and the Regular Record Date
for any interest payable on any Interest Payment Date; (8) the place or places
where the principal of, premium (if any) and interest on such Debt Securities
will be payable; (9) whether such Debt Securities will be Senior Securities or
Subordinated Securities; (10) the period or periods within which, the events
upon the occurrence of which, the price or prices at which, such Debt
Securities may, pursuant to any optional or mandatory provisions, be redeemed
or purchased, in whole or in part, by the Company and any terms and conditions
relevant thereto; (11) the obligation of the Company, if any, to redeem or
repurchase such Debt Securities at the option of the Holders; (12) the
denominations in which any such Debt Securities will be issuable, if other
than denominations of $1,000 and any integral multiple thereof; (13) the
currency, currencies or currency unit or units of payment of principal of and
any premium and interest on such Debt Securities if other than U.S. dollars;
(14) any index or formula used to determine the amount of payments of
principal of or any premium and interest on such Debt Securities; (15) if the
principal of or any premium or interest on such Debt Securities is to be
payable, at the election of the Company or a Holder thereof, in one or more
currencies or currency units other than that or those in which such Debt
Securities are stated to be payable, the currency, currencies or currency
units in which payment of the principal shall be payable, and the periods
within which and the terms and conditions upon which such election is to be
made; (16) if other than the full principal amount thereof, the portion of the
principal amount of such Debt Securities of the series which will be payable
upon declaration of the acceleration of the Maturity thereof; (17) the
applicability of certain covenants for the benefit of the holders of such Debt
Securities; (18) the applicability of any provisions
 
                                       5
<PAGE>
 
described under "--Defeasance"; (19) the terms and conditions, if any,
pursuant to which such Debt Securities are convertible or exchangeable into
Common Stock or other securities; and (20) any other terms of such Debt
Securities not inconsistent with the provisions of the respective Indentures.
 
  Debt Securities may be issued at a discount from their principal amount.
United States Federal income tax considerations and other special
considerations applicable to any such Original Issue Discount Securities may
be described in the applicable Prospectus Supplement.
 
  If the purchase price of any of the Debt Securities is denominated in a
foreign currency or currencies or a foreign currency unit or units or if the
principal of and any premium and interest on any series of Debt Securities is
payable in a foreign currency or currencies or a foreign currency unit or
units, the restrictions, elections, general tax considerations, specific terms
and other information with respect to such issue of Debt Securities and such
foreign currency or currencies or foreign currency unit or units will be set
forth in the applicable Prospectus Supplement.
 
SUBORDINATION OF SUBORDINATED SECURITIES
 
  The indebtedness evidenced by the Subordinated Securities will be
subordinated and junior in right of payment to the extent set forth in the
Subordinated Indenture to the prior payment in full of amounts then due on all
Senior Indebtedness. No payment shall be made by the Company on account of
principal of (or premium, if any) or interest on the Subordinated Securities
or on account of the purchase or other acquisition of Subordinated Securities,
if there shall have occurred and be continuing a default in the payment of
principal (or premium, if any) or interest on any Senior Indebtedness when it
becomes due or, if any event of default with respect to any Senior
Indebtedness which automatically accelerates or permits the acceleration of
the maturity of such Senior Indebtedness shall have occurred, unless and until
such default or event of default shall have been cured or waived or, in the
case of non-payment defaults, such event of default is not the subject of
judicial proceedings or the maturity of such Senior Indebtedness is not
accelerated 180 days after the Company is given written notice of such
default. By reason of these provisions, in the event of a default with respect
to any Senior Indebtedness, whether now outstanding or hereafter issued,
payments of principal of (and premium, if any) and interest on the
Subordinated Securities may not be permitted to be made until such default is
cured or such Senior Indebtedness is paid in full.
 
  Upon any distribution of assets of the Company upon any receivership,
dissolution, winding-up, liquidation, reorganization or similar proceedings of
the Company, whether voluntary or involuntary, or in bankruptcy or insolvency,
all principal of (and premium, if any) and interest due upon all Senior
Indebtedness must be paid in full before the Holders of the Subordinated
Securities or the Trustee is entitled to receive or retain any assets so
distributed in respect of the Subordinated Securities. By reason of this
provision, in the event of insolvency Holders of the Subordinated Securities
may recover less, ratably, than other creditors of the Company, including
holders of Senior Indebtedness.
 
  Unless otherwise defined in the applicable Prospectus Supplement, "Senior
Indebtedness" means the principal of (and premium, if any) and interest on (a)
all indebtedness of the Company (including indebtedness of others guaranteed
by the Company) other than the Subordinated Securities, which is (i) for money
borrowed or (ii) evidenced by a note or similar instrument given in connection
with the acquisition of any businesses, properties or assets of any kind, (b)
obligations of the Company as lessee under leases required to be capitalized
on the balance sheet of the lessee under generally accepted accounting
principles and (c) amendments, renewals, extensions, modifications and
refunding of any such indebtedness or obligation, in any such case whether
outstanding on the date of the Indenture or thereafter created, incurred or
assumed, unless in any case in the instrument creating or evidencing any such
indebtedness or obligation or pursuant to which the same is outstanding it is
provided that such indebtedness or obligation is not superior in right of
payment to the Subordinated Securities or it is provided that such obligation
is subordinated to senior
 
                                       6
<PAGE>
 
indebtedness to substantially the same extent as the Subordinated Securities
are subordinated to Senior Indebtedness.
 
FORM, EXCHANGE, REGISTRATION, CONVERSION, TRANSFER AND PAYMENT
 
  Unless otherwise indicated in the applicable Prospectus Supplement, the Debt
Securities will be issued only in fully registered form in denominations of
$1,000 or integral multiples thereof. Unless otherwise indicated in the
applicable Prospectus Supplement, payment of principal of (and premium, if
any) and interest on the Debt Securities will be payable, and the exchange,
conversion and transfer of Debt Securities will be registerable, at the office
or agency of the Company maintained for such purposes and at any other office
or agency maintained for such purpose. No service charge will be made for any
registration of transfer or exchange of the Debt Securities, but the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge imposed in connection therewith.
 
  All moneys paid by the Company to a Paying Agent for the payment of
principal of (and premium, if any) or interest on any Debt Security which
remain unclaimed for two years after such principal, premium or interest has
become due and payable may be repaid to the Company and thereafter the Holder
of such Debt Security may look only to the Company for payment thereof.
 
BOOK-ENTRY DEBT SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on
behalf of, a Depositary ("Depositary") or its nominee identified in the
applicable Prospectus Supplement. In such a case, one or more Global
Securities will be issued in a denomination or aggregate denominations equal
to the portion of the aggregate principal amount of Outstanding Debt
Securities of the series to be represented by such Global Security or
Securities. Unless and until it is exchanged in whole or in part for Debt
Securities in registered form, a Global Security may not be registered for
transfer or exchange except as a whole by the Depositary for such Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any nominee to a successor Depositary or a nominee of such successor
Depositary and except in the circumstances described in the applicable
Prospectus Supplement.
 
  The specific terms of the depositary arrangement with respect to any portion
of a series of Debt Securities to be represented by a Global Security will be
described in the applicable Prospectus Supplement. The Company expects that
the following provisions will apply to depositary arrangements.
 
  Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities which are to be represented by a Global Security to be deposited
with or on behalf of a Depositary will be represented by a Global Security
registered in the name of such Depositary or its nominee. Upon the issuance of
such Global Security, the Depositary will credit, on its book-entry
registration and transfer system, the respective principal amounts of the Debt
Securities represented by such Global Security to the accounts of institutions
that have accounts with such Depositary or its nominee ("participants"). The
accounts to be credited will be designated by the underwriters or agents with
respect to the offer of such Debt Securities or by the Company, if such Debt
Securities are offered and sold directly by the Company. Ownership of
beneficial interest in such Global Security will be limited to participants or
Persons that may hold interest through participants. Ownership of beneficial
interests by participants in such Global Security will be shown on, and the
transfer of that ownership interest within such participant will be effected
only through, records maintained by such participant. The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of such securities in certificated form. The foregoing limitations
and such laws may impair the ability to transfer beneficial interests in such
Global Securities.
 
                                       7

  So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or Holder of the Securities
represented by such Global Security for all purposes under the applicable
Indenture. Unless otherwise specified in the applicable Prospectus Supplement,
owners of beneficial interests in such Global Security will not be entitled to
have Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of Debt Securities of such series in certificated form and will not
be considered the Holders thereof for any purposes under the applicable
Indenture. Accordingly, each Person owning a beneficial interest in such
Global Security must rely on the procedures of the Depositary and, if such
Person is not a participant, on the procedures of the participant through
which such Person owns its interest, to exercise any rights of a Holder under
the applicable Indenture. The Company understands that under existing industry
practices, if the Company requests any action of Holders or any owner of a
beneficial interest in such Global Security desires to give any notice or take
any action a Holder is entitled to give or take under an Indenture, the
Depositary would authorize the participants to give such notice or take such
action, and participants would authorize beneficial owners owning through such
participants to give such notice or take such action or would otherwise act
upon the instructions of beneficial owners owning through them.
 
  Principal of (and premium, if any) and interest on a Global Security will be
payable in the manner described in the applicable Prospectus Supplement.
 
CERTAIN COVENANTS OF THE COMPANY
 
  Specific covenants for the benefit of the holders of a particular series of
Debt Securities will be set forth in the applicable Prospectus Supplements.
These may include, among others, covenants restricting the incurrence of
additional Senior Indebtedness and restricting certain sale and leaseback
transactions and covenants affording a Holder the right to have Debt
Securities repurchased by the Company upon the happening of certain events.
 
EVENTS OF DEFAULT
 
  The following are Events of Default under the Indentures with respect of
Debt Securities of any series: (a) failure to pay principal of (or premium, if
any on) any Debt Security of that series when due; (b) failure to pay any
interest on any Debt Security of that series when due and the continuance of
such failure for 30 days; (c) failure to make any sinking fund payment, when
due, in respect of any Debt Security of that series; (d) failure to perform
any other covenant of the Company in the applicable Indenture (other than a
covenant included in such Indenture solely for the benefit of a series of Debt
Securities other than that series), and the continuance of such failure for 30
days after written notice as provided in the respective Indentures; (e)
failure to pay at the final maturity thereof the principal of, or acceleration
of, any indebtedness for money borrowed by the Company in excess of the amount
specified in the applicable Prospectus Supplement with respect to Debt
Securities of that series, if such indebtedness is not discharged, or such
acceleration is not annulled, as provided in the respective Indentures; (f)
certain events of bankruptcy, insolvency or reorganization; and (g) any other
Event of Default provided with respect to Debt Securities of that series.
 
  If an Event of Default with respect to Outstanding Debt Securities of any
series shall occur and be continuing, either the Trustee or the Holders of at
least 25% in aggregate principal amount of the Outstanding Debt Securities of
the series by notice as provided in the respective Indentures may declare the
principal amount (or, if the Debt Securities of that series are Original Issue
Discount Securities, such portion of the principal amount as may be specified
in the terms of that series) of all Debt Securities of that series to be due
and payable immediately. However, at any time after a declaration of
acceleration with respect to Debt Securities of any series has been made, but
before a judgement or decree based on such acceleration has been obtained, the
Holders of a majority in principal amount of the Outstanding Debt Securities
of that series may, under certain circumstances,
 
                                       8
<PAGE>
 
rescind and annul such acceleration. For information as to waiver of defaults,
see "--Modification and Waiver."
 
  The Indentures provide that, subject to the duty of the respective Trustees
thereunder during an Event of Default to act with the required standard of
care, such Trustee will be under no obligation to exercise any of its rights
or powers under the respective Indentures at the request or direction of any
of the Holders, unless such Holders shall have offered to such Trustee
reasonable security or indemnity. Subject to certain provisions, including
those requiring security or indemnifications of the Trustees, the Holders of a
majority in principal amount of the Outstanding Debt Securities of any series
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the applicable Trustee, or exercising
any trust or power conferred on such Trustee, with respect to the Debt
Securities of that series.
 
  No Holder of a Debt Security of any series will have any right to institute
any proceeding with respect to the applicable Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the applicable
Trustee written notice of a continuing Event of Default (as defined) and
unless also the Holders of at least 25% in aggregate principal amount of the
outstanding Debt Securities of the same series shall have made written
request, and offered reasonable indemnity, to the Trustee to institute such
proceeding as trustee, and the Trustee shall not have received from the
Holders of a majority in aggregate principal amount of the outstanding Debt
Securities of the same series a direction inconsistent with such request and
shall have failed to institute such proceeding within 60 days. However, such
limitations do not apply to a suit instituted by a Holder of a Debt Security
for enforcement of payment of the principal of and interest on such Debt
Security on or after the respective due dates expressed in such Debt Security.
 
  The Company will be required to furnish to the Trustees annually a statement
as to the performance by the Company of its obligations under the respective
Indentures and as to any default in such performance.
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of the respective Indentures may be made by the
Company and the Trustee with the consent of the Holders of not less than a
majority in aggregate principal amount of the Outstanding Debt Securities of
each series affected thereby; provided, however, that no such modification or
amendment may, without the consent of the Holder of each Outstanding Debt
Security affected thereby: (a) change the Stated Maturity of the principal of,
or any installment of principal of, or interest on, any Debt Security; (b)
reduce the principal amount of, the rate of interest on (or premium, if any)
payable upon the redemption of, any Debt Security; (c) reduce the amount of
principal of an Original Issue Discount Security payable upon acceleration of
the Maturity thereof; (d) change the place or currency of payment of principal
of (or premium, if any) or interest on any Debt Security; (e) impair the right
to institute suit for the enforcement of any payment on or with respect to any
Debt Security on or after the Stated Maturity or Redemption Date thereof; or
(f) reduce the percentage in principal amount of Outstanding Debt Securities
of any series, the consent of the Holders of which is required for
modification or amendment of the applicable Indenture or for waiver of
compliance with certain provisions of the applicable Indenture or for waiver
of certain defaults.
 
  The Holders of at least a majority in aggregate principal amount of the
Outstanding Debt Securities of any series may on behalf of the Holders of all
Debt Securities of that series waive, insofar as that series is concerned,
compliance by the Company with certain covenants of the applicable Indenture.
The Holders of not less than a majority in principal amount of the Outstanding
Debt Securities of any series may, on behalf of the Holders of all Debt
Securities of that series, waive any past default under the applicable
Indenture with respect to that series, except a default in the payment of the
principal of (or premium, if any) or interest on, any Debt Security of that
series or in respect of a
 
                                       9
<PAGE>
 
provision which under the applicable Indenture cannot be modified or amended
without the consent of the Holder of each Outstanding Debt Security of that
series affected.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Company, without the consent of any Holders of Outstanding Debt
Securities, may consolidate with or merge into, or transfer or lease its
assets substantially as an entirety to, any Person, and any other Person may
consolidate with or merge into, or transfer or lease its assets substantially
as an entirety to, the Company, provided (a) that the Person (if other than
the Company) formed by such consolidation or into which the Company is merged
or which acquires or leases the assets of the Company substantially as an
entirety is a Person organized and existing under the laws of any United
States jurisdiction and assumes the Company's obligations on the Debt
Securities and under the respective Indentures, (b) that after giving effect
to such transaction no Event of Default, shall have occurred and be
continuing, and (c) that certain other conditions are met.
 
DEFEASANCE
 
  If so indicated in the applicable Prospectus Supplement with respect to the
Debt Securities of a series, the Company, at its option, (i) will be
discharged from any and all obligations in respect of the Debt Securities of
such series (except for certain obligations to register the transfer or
exchange of Debt Securities of such series, to replace destroyed, stolen, lost
or mutilated Debt Securities of such series, and to maintain an office or
agency in respect of the Debt Securities and hold moneys for payment in trust)
or (ii) will be released from its obligations to comply with covenants and the
occurrence of an event described in clause (d) under "Events of Default" above
with respect to any defeased covenant and clauses (e) and (g) of the "Events
of Default" above shall no longer be an Event of Default if, in either case,
the Company irrevocably deposits with the Trustee, in trust, money or U.S.
Government Obligations that through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an
amount sufficient to pay all the principal of (and premium, if any) and any
interest on the Debt Securities of such series on the dates such payments are
due (which may include one or more redemption dates designated by the Company)
in accordance with the terms of such Debt Securities. Such a trust may only be
established if, among other things, (a) no Event of Default or event which
with the giving of notice or lapse of time, or both, would become an Event of
Default under the applicable Indenture shall have occurred and be continuing
on the date of such deposit, (b) no Event of Default described under clause
(f) under "Events of Default" above or event which with the giving of notice
or lapse of time, or both, would become an Event of Default described under
such clause (f) shall have occurred and be continuing at any time during the
period ending on the 91st day following such date of deposit, and (c) the
Company shall have delivered an Opinion of Counsel to the effect that the
Holders of the Debt Securities will not recognize gain or loss for United
States Federal income tax purposes as a result of such deposit or defeasance
and will be subject to United States Federal income tax in the same manner as
if such defeasance had not occurred. In the event the Company omits to comply
with its remaining obligations under the applicable Indenture after a
defeasance of such Indenture with respect to the Debt Securities of any series
as described under clause (ii) above and the Debt Securities of such series
are declared due and payable because of the occurrence of any undefeased Event
of Default, the amount of money and U.S. Government Obligations on deposit
with the Trustee may be insufficient to pay amounts due on the Debt Securities
of such series at the time of the acceleration resulting from such Event of
Default. However, the Company will remain liable in respect of such payments.
 
  Notwithstanding the description set forth under "Subordination of
Subordinated Securities", in the event that the Company deposits money or U.S.
Government Obligations in compliance with the Subordinated Indenture in order
to defease all or certain of its obligations with respect to any Subordinated
Securities, the moneys or U.S. Government Obligations so deposited will not be
subject
 
                                      10
<PAGE>
 
to the subordination provisions of the Subordinated Indenture and the
indebtedness evidenced by such Subordinated Securities will not be
subordinated in right of payment to the holders of Senior Indebtedness to the
extent of the moneys or U.S. Government Obligations so deposited.
 
GOVERNING LAW
 
  The Indentures and the Debt Securities will be governed by, and construed in
accordance with, the laws of the State of New York.
 
REGARDING THE TRUSTEE
 
  The Indentures contain certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize for its own account on certain property received
in respect of any such claim as security or otherwise. The Trustee will be
permitted to engage in certain other transactions; however, if it acquires any
conflicting interest and there is a default under the Debt Securities, it must
eliminate such conflict or resign.
 
  Pursuant to the Trust Indenture Act of 1939, as amended, if both Senior
Securities and Subordinated Securities are outstanding and a default should
occur with respect to either the Senior Securities under the Senior Indenture
or the Subordinated Securities under the Subordinated Indenture, and if the
same entity is then acting as Trustee under both Indentures, such Trustee
would be required to resign as Trustee under one of the Indentures within 90
days of such default unless such default were cured, duly waived or otherwise
eliminated.
 
                        DESCRIPTION OF PREFERRED STOCK
 
  The following is a description of certain general terms and provisions of
the Preferred Stock. The particular terms of any series of Preferred Stock
will be described in the applicable Prospectus Supplement. If so indicated in
a Prospectus Supplement, the terms of any such series may differ from the
terms set forth below. Certain provisions applicable to the Preferred Stock
are set forth under "Description of Common Stock."
 
  The summary of terms of the Company's preferred stock (including the
Preferred Stock) contained in this Prospectus does not purport to be complete
and is subject to, and qualified in its entirety by, the provisions of the
Company's Certificate of Incorporation and the certificate of designations
relating to each series of the Preferred Stock (the "Certificate of
Designations"), which will be filed as an exhibit to or incorporated by
reference in the Registration Statement of which this Prospectus is a part at
or prior to the time of issuance of such series of the Preferred Stock.
 
  The Company's Certificate of Incorporation authorizes the issuance of
5,000,000 shares of preferred stock, par value of $.001 per share. As of the
date of this Prospectus, there were no shares of the Company's preferred stock
outstanding. The Company's preferred stock may be issued from time to time in
one or more series, without stockholder approval. Subject to limitations
prescribed by law, the Board of Directors is authorized to determine the
voting powers (if any), designation, preferences and relative, participating,
optional or other special rights, and qualifications, limitations or
restrictions thereof, for each series of preferred stock that may be issued,
and to fix the number of shares of each such series. Thus, the Board of
Directors, without stockholder approval, could authorize the issuance of
preferred stock with voting, conversion and other rights that could adversely
affect the voting power and other rights of holders of Common Stock or other
series of preferred stock or that could have the effect of delaying, deferring
or preventing a change in control of the Company. See "Description of Common
Stock."
 
                                      11
<PAGE>
 
  The Preferred Stock shall have the dividend, liquidation, redemption and
voting rights set forth below unless otherwise provided in a Prospectus
Supplement relating to a particular series of the Preferred Stock. The
applicable Prospectus Supplement will describe the following terms of the
series of Preferred Stock in respect of which this Prospectus is being
delivered: (1) the designation and stated value per share of such Preferred
Stock and the number of shares offered; (2) the amount of liquidation
preference per share; (3) the initial public offering price at which such
Preferred Stock will be issued; (4) the dividend rate (or method of
calculation), the dates on which dividends shall be payable and the dates from
which dividends shall commence to cumulate, if any; (5) any redemption or
sinking fund provisions; (6) any conversion or exchange rights; and (7) any
additional voting, dividend, liquidation, redemption, sinking fund and other
rights, preferences, privileges, limitations and restrictions.
 
GENERAL
 
  The Preferred Stock offered hereby may be issued in one or more series. The
holders of Preferred Stock will have no preemptive rights. Each share of
Preferred Stock, upon issuance against full payment of the purchase price
therefor, will be fully paid and nonassessable. Neither the par value nor the
liquidation preference is indicative of the price at which the Preferred Stock
will actually trade on or after the date of issuance. The applicable
Prospectus Supplement will contain a description of certain United States
Federal income tax consequences relating to the purchase and ownership of the
series of Preferred Stock offered by such Prospectus Supplement.
 
RANK
 
  The Preferred Stock shall, with respect to dividend rights and rights on
liquidation, winding up and dissolution of the Company, rank prior to the
Company's Common Stock and to all other classes and series of equity
securities of the Company now or hereafter authorized, issued or outstanding
(the Common Stock and such other classes and series of equity securities
collectively may be referred to herein as the "Junior Stock"), other than any
classes or series of equity securities of the Company ranking on a parity with
(the "Parity Stock") or senior to the Preferred Stock as to dividend rights
and rights upon liquidation, winding up or dissolution of the Company. The
Preferred Stock shall be junior to all outstanding indebtedness of the
Company.
 
DIVIDENDS
 
  Holders of shares of Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of Directors out of funds of the Company legally
available for payment, cash dividends, or if not cash dividends, dividends
payable in Securities of the Company, payable at such dates and at such rates
per share per annum as set forth in the applicable Prospectus Supplement. Such
rate may be fixed or variable or both. Each declared dividend shall be payable
to holders of record as they appear at the close of business on the stock
books of the Company on such record dates, not more than 60 calendar days
preceding the payment dates therefor, as are determined by the Board of
Directors (each of such dates, a "Record Date").
 
  Such dividends may be cumulative or noncumulative, as provided in the
applicable Prospectus Supplement. If dividends on a series of Preferred Stock
are noncumulative and if the Board of Director fails to declare a dividend in
respect of a dividend period with respect to such series, then holders of such
Preferred Stock will have no right to receive a dividend in respect of such
dividend period, and the Company will have no obligation to pay the dividend
for such period, whether or not dividends are declared payable on any future
dividend payment dates. Dividends on the shares of each series of Preferred
Stock for which dividends are cumulative will accrue from the date on which
the Company initially issues shares of such series.
 
                                      12
<PAGE>
 
  No full dividends shall be declared or paid or set apart for payment on
preferred stock of the Company of any series ranking, as to dividends, on a
parity with the series of Preferred Stock offered by the accompanying
Prospectus Supplement for any period unless full dividends for the immediately
preceding dividend period on such Preferred Stock (including any accumulation
in respect of unpaid dividends for prior dividend periods, if dividends on
such Preferred Stock are cumulative) have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof is
set apart for such payment. When dividends are not so paid in full (or a sum
sufficient for such full payment is not so set apart) upon such Preferred
Stock and any other preferred stock of the Company ranking on a parity as to
dividends with the Preferred Stock, dividends upon shares of such Preferred
Stock and dividends on such other preferred stock shall be declared pro rata
so that the amount of dividends declared per share on such Preferred Stock and
such other preferred stock shall in all cases bear to each other the same
ratio that accrued dividends for the then-current dividend period per share on
the shares of such Preferred Stock (including any accumulation in respect of
unpaid dividends for prior dividend period, if dividends on such Preferred
Stock are cumulative) and accrued dividends, including required or permitted
accumulation, if any, on shares of such other preferred stock, bear to each
other. Unless full dividends on the series of Preferred Stock offered by the
accompanying Prospectus Supplement have been declared and paid or set apart
for payment for the immediately preceding dividend period (including any
accumulation in respect of unpaid dividends for prior dividend periods, if
dividends on such Preferred Stock are cumulative) (a) no cash dividend or
distribution (other than in shares of Junior Stock) may be declared, set aside
or paid on the Junior Stock, (b) the Company may not repurchase, redeem or
otherwise acquire any shares of its Junior Stock (except by conversion into or
exchange for Junior Stock) and (c) the Company may not, directly or
indirectly, repurchase, redeem or otherwise acquire any shares of Preferred
Stock or Parity Stock otherwise than pursuant to certain pro rata offers to
purchase or a concurrent redemption of all, or a pro rata portion, of the
outstanding shares of such Preferred Stock and Parity Stock (except by
conversion into or exchange for Junior Stock).
 
CONVERTIBILITY
 
  The terms, if any, on which shares of Preferred Stock of any series may be
exchanged for or converted (mandatorily or otherwise) into shares of Common
Stock of the Company or another series of Preferred Stock or other securities
of the Company will be set forth in the Prospectus Supplement relating
thereto. See "Description of Common Stock."
 
REDEMPTION
 
  The terms, if any, on which shares of Preferred Stock of any series may be
redeemed will be set forth in the Prospectus Supplement relating thereto.
 
LIQUIDATION
 
  Unless otherwise specified in the applicable Prospectus Supplement, in the
event of a voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, the holders of a series of Preferred Stock will be
entitled, subject to the rights of creditors, but before any distribution or
payment to the holders of Common Stock or any other security ranking junior to
the Preferred Stock on liquidation, dissolution or winding up of the Company,
to receive an amount per share as set forth in the related Prospectus
Supplement plus accrued and unpaid dividends. If the amounts available for
distribution with respect to the Preferred Stock and all other outstanding
stock of the Company ranking on a parity with the Preferred Stock upon
liquidation are not sufficient to satisfy the full liquidation rights of all
the outstanding Preferred Stock and stock ranking on a parity therewith, then
the holders of each series of such stock will share ratably in any such
distribution of assets in proportion to the full respective preferential
amount (which in the case of preferred stock may include accumulated
 
                                      13
<PAGE>
 
dividends) to which they are entitled. After payment of the full amount of the
liquidation preference, the holders of shares of Preferred Stock will not be
entitled to any further participation in any distribution of assets by the
Company.
 
VOTING
 
  The Preferred Stock of a series will not be entitled to vote, except as
provided in the applicable Prospectus Supplement and as required by applicable
law.
 
NO OTHER RIGHTS
 
  The shares of a series of Preferred Stock will not have any preferences,
voting powers or relative, participating, optional or other special rights
except as set forth above or in the related Prospectus Supplement, the
Certificate of Incorporation and in the Certificate of Designations or as
otherwise required by law.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for each series of Preferred Stock will be
described in the Prospectus Supplement relating thereto.
 
                          DESCRIPTION OF COMMON STOCK
 
  The Company's Certificate of Incorporation authorizes the issuance of
75,000,000 shares of Common Stock, par value $.001 per share. As of December
22, 1996 there were 38,895,067 shares of Common Stock outstanding. The
following is a summary of the rights and privileges of the holders of Common
Stock. These rights and privileges are subject to the rights and privileges of
the holders of preferred stock of the Company (including Preferred Stock, if
any, which may hereafter be issued):
 
  Dividend Rights. Subject to the preferential rights of the holders of shares
of preferred stock of the Company, holders of Common stock are entitled to
share ratably in such dividends, if any, as may be declared from time to time
by the Board of Directors out of funds legally available therefor.
 
  Voting Rights. Holders of Common Stock are entitled to one vote per share on
all matters submitted to a vote of the Company's stockholders. The Common
Stock does not have cumulative voting rights, which means that (subject to the
rights of the holders of preferred stock of the Company) the holders of a
majority of the shares voting for election of directors can elect all members
of the Board of Directors.
 
  Liquidation Rights. Upon liquidation, dissolution or winding up of the
Company, holders of Common Stock will be entitled to share ratably in the
assets of the Company legally available for distribution to stockholders after
payment of liabilities and subject to the prior rights of any holders of
preferred stock of the Company then outstanding.
 
  Other Rights. Holders of Common Stock have no conversion, sinking fund,
redemption, preemptive or subscription rights.
 
  The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company, 40 Wall Street, New York, NY 10005.
 
  Special Meetings. The Certificate of Incorporation permits special meetings
of stockholders to be called only by stockholders holding in the aggregate not
less than 40% of the total shares of stock entitled to vote for directors.

                             PLAN OF DISTRIBUTION
 
  The Company may offer Securities to or through underwriters, through agents
or directly to other purchasers.
 
  The distribution of Securities may be effected from time to time in one or
more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to such market prices
or at negotiated prices.
 
  In connection with the sale of Securities, underwriters or agents may
receive compensation from the Company or from purchasers in the form of
discounts, concessions or commissions. Underwriters, agents and dealers
participating in the distribution of the Securities may be deemed to be
underwriters within the meaning of the Securities Act.
 
  Pursuant to agreements which may be entered into between the Company and any
underwriters or agents named in the applicable Prospectus Supplement, such
underwriters or agents may be entitled to indemnification by the Company
against certain liabilities, including liabilities under the Securities Act.
 
  If so indicated in the applicable Prospectus Supplement, the Company will
authorize underwriters or other persons acting as agents for the Company to
solicit offers by certain institutional investors to purchase Debt Securities
or Preferred Stock from the Company pursuant to contracts providing for
payment and delivery on a future date. Institutions with which such contracts
may be made include commercial and saving banks, insurance companies, pension
funds, investment companies, educational and charitable institutions and
others, but shall in all cases be subject to the approval of the Company. The
obligations of the purchaser under any such contract will not be subject to
any conditions except (i) the investment in the Debt Securities or Preferred
Stock by the institution shall not at the time of delivery be prohibited by
the law of any jurisdiction in the United states to which such institution is
subject, and (ii) if a portion of the Debt Securities or Preferred Stock is
being sold to underwriters, the Company shall have sold to such underwriters
the Debt Securities or Preferred Stock not sold for delayed delivery.
Underwriters and such other persons will not have any responsibility in
respect of the validity or performance of such contacts.
 
  All Debt Securities, Preferred Stock and Warrants offered may be a new issue
of securities with no established trading market. Any underwriters to whom
such Debt Securities, Preferred Stock and Warrants are sold by the Company for
public offering and sale may make a market in such Debt Securities, Preferred
Stock and Warrants, but such underwriters will not be obligated to do so and
may discontinue any market making at any time without notice. No assurance can
be given as to the liquidity of or the trading markets for any Debt
Securities, Preferred Stock or Warrants.
 
  Certain of the underwriters or agents and their associates may be engaged in
transactions with and perform services for the Company in the ordinary course
of business.
 
  The specific terms and manner of sale of the Securities in respect of which
this Prospectus is being delivered are set forth or summarized in the
applicable Prospectus Supplement.
