                                  THE COMPANY
 
   
     Waste Connections is a regional, integrated solid waste services company
that provides solid waste collection, transfer, disposal and recycling services
in secondary markets of the Western U.S. As of May 15, 1998, the Company served
more than 139,000 commercial, industrial and residential customers in
Washington, California, Idaho, Wyoming and South Dakota. The Company currently
owns nine collection operations and operates three transfer stations, one
Subtitle D landfill and one recycling facility. See "Business -- Introduction"
and "-- Services."
    
 
   
     Waste Connections was founded in September 1997 to execute an
acquisition-based growth strategy in secondary markets of the Western U.S. The
Company has acquired ten solid waste services businesses since its formation and
has identified more than 300 independent operators of such businesses in the
states where it currently operates, many of which it believes may be suitable
for acquisition by the Company. In addition, the Company is currently assessing
potential acquisitions of solid waste services operations in several other
Western States. See "Business -- Acquisition Program."
    
 
     The Company has targeted secondary markets in the Western U.S. because it
believes that (i) a large number of independent solid waste services companies
suitable for acquisition by the Company are located in these markets; (ii) there
is less competition in these markets from large, well-capitalized solid waste
services companies; and (iii) these markets have strong projected economic and
population growth rates. In addition, the Company's senior management team has
extensive experience acquiring and operating solid waste services businesses in
the Western U.S.
 
     The Company has developed a market-based operating strategy tailored to the
competitive and regulatory factors that affect its markets. In certain Western
U.S. markets, where waste collection services are governed by exclusive
franchise agreements, municipal contracts and governmental certificates
(referred to in Washington as "G certificates"), the Company generally intends
to pursue a collection-based operating strategy. In these markets, the Company
believes that controlling the waste stream by providing collection services
under exclusive franchise agreements, municipal contracts and governmental
certificates is often more important to a solid waste services company's growth
and profitability than owning or operating landfills. In markets where the
Company considers ownership of landfills advantageous due to competitive and
regulatory factors, the Company generally intends to pursue an integrated,
disposal-based strategy. See "Business -- Strategy."
 
     The Company's objective is to build a leading solid waste services company
in the secondary markets of the Western U.S. by (i) acquiring collection,
transfer, disposal and recycling operations in new markets and through "tuck-in"
acquisitions in existing markets; (ii) securing additional exclusive franchises,
municipal contracts and governmental certificates; (iii) generating internal
growth in existing markets by increasing market penetration and adding services
to its existing operations; and (iv) enhancing profitability by increasing
operating efficiencies of existing and acquired operations. The Company believes
that the experience of the members of its senior management team and their
knowledge of and reputation in the solid waste industry in the
 
                                        3
<PAGE>   5
 
Company's targeted markets will provide the Company with competitive advantages
as it pursues its growth strategy. See "Business -- Strategy."
 
     The Company was incorporated in Delaware in 1997. Its principal executive
offices are located at 2260 Douglas Boulevard, Suite 280, Roseville, California
95661, and its telephone number is (916) 772-2221.
 
                                   BACKGROUND
 
     In September 1997, the Company joined with two other parties to bid on
certain solid waste and recycling businesses offered for sale by Browning-Ferris
Industries, Inc. ("BFI"). The Company acquired the stock of Browning-Ferris
Industries of Washington, Inc., a provider of solid waste services to more than
78,000 customers through three municipal contracts and one G certificate in and
around Clark County, Washington, and the stock of its subsidiary, Fibres
International, Inc., a provider of solid waste services to more than 24,000
customers through eight municipal contracts and one G certificate in King and
Snohomish Counties, Washington. The acquired companies subsequently changed
their names to Waste Connections of Washington, Inc. and Waste Connections
International, Inc., respectively. The two other parties acquired selected BFI
solid waste collection and transportation assets and operations in Idaho, and
BFI's recycling assets and operations in Washington, Idaho and Oklahoma.
 
                              RECENT DEVELOPMENTS
 
MADERA ACQUISITION
 
     Effective February 1, 1998, the Company acquired Madera Disposal Systems,
Inc. ("Madera"), an integrated solid waste services company operating in north
central California, with 1997 revenues of approximately $7.8 million. In
connection with the Madera acquisition, the Company acquired one franchise
agreement and one municipal contract, pursuant to which it serves more than
9,000 commercial, industrial and residential customers, and agreements to
operate two transfer stations, one Subtitle D landfill (the "Fairmead Landfill")
and one recycling facility. The Fairmead Landfill is estimated to have a
remaining life of approximately 26 years.
 
IDAHO ACQUISITIONS
 
     On January 30, 1998, the Company acquired from affiliates of the Company
the stock of Waste Connections of Idaho, Inc., a provider of solid waste
collection services to more than 10,000 customers in and around Idaho Falls and
Pocatello, Idaho. Waste Connections of Idaho, Inc. was formed in September 1997
by affiliates of the Company for the purpose of acquiring certain assets of
Browning-Ferris Industries of Idaho, Inc. See "Certain Transactions."
 
     Effective March 1, 1998, the Company acquired certain solid waste
collection assets from Hunter Enterprises, Inc., a solid waste services company
located in eastern Idaho that serves approximately 2,800 customers.
 
WYOMING ACQUISITIONS
 
     On April 8, 1998, the Company acquired solid waste collection assets from
A-1 Disposal, Inc. and Jesse's Disposal, which together serve approximately
2,300 customers in northeastern Wyoming.
 
   
     On May 11, 1998, the Company acquired T&T Disposal, Inc., a provider of
solid waste and recyclables collection services to more than 500 customers in
eastern Wyoming.

SOUTH DAKOTA ACQUISITIONS
    
 
   
     On May 8, 1998, the Company acquired Sowers' Sanitation, Inc. and Sunshine
Sanitation Incorporated, providers of solid waste and recyclables collection
services to an aggregate of more than 7,000 customers in western South Dakota.
    
 
LETTERS OF INTENT TO ACQUIRE ADDITIONAL OPERATIONS
 
   
     As of May 15, 1998, the Company had entered into nonbinding, preliminary
letters of intent relating to the possible acquisition of five collection and
transfer companies and one integrated collection and landfill company, which the
Company estimates represent aggregate annualized revenues of more than $17.0
million, and which would result in expansion into five new markets. There can be
no assurance that actual revenues realized by the Company from the successful
acquisition of these potential acquisition candidates will not differ materially
from the Company's estimate or that any of these letters of intent will lead to
completed acquisitions on the terms currently contemplated.
    
 
AMENDMENT AND INCREASE OF CREDIT FACILITY
 
   
     On April 21, 1998, the Company received a preliminary letter of commitment
to amend and increase its credit facility with a syndicate of banks led by
BankBoston, N.A. The amendment is contingent on this offering and will, among
other things, increase the Company's borrowing capacity from $25.0 million to
$60.0 million, modify certain covenants and lower the Company's borrowing costs.
As of May 15, 1998, the aggregate outstanding principal indebtedness under the
current credit facility was approximately $20.1 million.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing the shares of Common Stock offered by this
Prospectus. This Prospectus contains certain forward-looking statements that
involve risks and uncertainties. Discussions containing such forward-looking
statements may be found in the material set forth under "Prospectus Summary,"
"Risk Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business," as well as in the Prospectus generally.
The cautionary statements contained in this Prospectus should be read as
applying to all related forward-looking statements wherever they appear in this
Prospectus. The Company's actual results could differ materially from those
discussed here as a result of various factors, including without limitation
those discussed below and elsewhere in this Prospectus.
 
     Limited Operating History; Integration of Completed Acquisitions. The
Company was formed in September 1997 and commenced operations on October 1,
1997. Accordingly, the Company has only a limited operating history upon which
to base an evaluation of its business and its prospects. The disclosures
regarding the Company contained in this Prospectus must be considered in light
of the risks, expenses and difficulties frequently encountered by companies in
their early stages of development. In addition, there can be no assurance that
the Company's recently assembled senior management team will be able to manage
the Company successfully and implement the Company's operating and growth
strategies effectively.
 
     The Company's effective integration of acquired businesses into its
organization and operations is and will continue to be important to the
Company's growth and future financial performance. A part of the Company's
strategy is to achieve economies of scale and operating efficiencies by
increasing its size through acquisitions. These goals may not be achieved unless
the Company effectively combines the operations of acquired businesses with its
existing operations. Because of the Company's limited operating history, there
can be no assurance that its recently assembled senior management team will
succeed in integrating the Company's completed and future acquisitions. Any
difficulties the Company encounters in the integration process could have a
material adverse effect on its business, financial condition and results of
operations.
 
     Growth Strategy Implementation; Ability to Manage Growth. The Company's
growth strategy includes (i) expanding through acquisitions, (ii) acquiring
additional exclusive franchise agreements and municipal contracts and (iii)
generating internal growth. The Company's ability to execute its growth strategy
will depend on a number of factors, including the success of existing and
emerging competition, the availability of acquisition targets, the ability to
maintain profit margins in the face of competitive pressures, the ability to
continue to recruit, train and retain qualified employees, the strength of
demand for the Company's services and the availability of capital to support its
growth.
 
     If the Company is able to execute its growth strategy, it may experience
periods of rapid growth. Such growth, if it occurs, could place a significant
strain on the Company's management, operational, financial and other resources.
The Company's ability to maintain and manage its growth effectively will require
it to expand its management information systems capabilities and its operational
and financial systems and controls. Moreover, the Company will need to attract,
train, motivate, retain and manage additional senior managers, technical
professionals and other employees. Any failure to expand the Company's
operational and financial systems and controls or to recruit and integrate
appropriate personnel at a pace consistent with the Company's revenue growth
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Strategy."
 
     Availability of Acquisition Targets. The Company expects that a substantial
part of its future growth will come from acquiring solid waste collection,
transfer and disposal operations. While the Company has identified numerous
acquisition candidates that it believes are suitable, no assurance
 
                                        8
<PAGE>   10
 
can be given that the Company will be able to negotiate their acquisition at
prices or on terms and conditions favorable to the Company. The Company's
failure to implement its acquisition strategy successfully would limit its
potential growth. See "Business -- Strategy" and "-- Acquisition Program."
 
     The Company competes for acquisition candidates with other entities, some
of which have greater financial resources than the Company. Increased
competition for acquisition candidates may result in fewer acquisition
opportunities being available to the Company, as well as less attractive
acquisition terms, including increased purchase prices. These circumstances may
increase acquisition costs to levels that are beyond the Company's financial
capability or pricing parameters or that may have an adverse effect on the
Company's results of operations and financial condition. A significant factor in
its ability to consummate acquisitions after completion of this offering will be
the relative attractiveness of shares of the Company's Common Stock as
consideration for potential acquisition candidates. This attractiveness may
depend in large part on the relative market price and capital appreciation
prospects of the Common Stock compared to the equity securities of the Company's
competitors. If the market price of the Company's Common Stock were to decline
materially over a prolonged period of time, the Company's acquisition program
could be materially adversely affected.
 
     Highly Competitive Industry. The solid waste services industry is highly
competitive and fragmented and requires substantial labor and capital resources.
Certain of the markets in which the Company competes or will likely compete are
served by one or more large, national solid waste companies, as well as by
numerous regional and local solid waste companies of varying sizes and
resources, some of which have accumulated substantial goodwill. The Company also
competes with counties, municipalities and solid waste districts that maintain
their own waste collection and disposal operations. These counties,
municipalities and solid waste districts may have financial advantages over the
Company, because of their access to user fees and similar charges, tax revenues
and tax-exempt financing. Certain of the Company's competitors may also be
better capitalized, have greater name recognition or be able to provide services
at a lower cost than the Company. The Company's inability to compete with
governmental service providers and larger and better capitalized companies could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
   
     The Company derives a substantial portion of its revenue from exclusive
municipal contracts and franchise agreements, of which a significant number will
be subject to competitive bidding at some time in the future. See
"Business -- Services." The Company intends to bid on additional municipal
contracts and franchise agreements as a means of adding customers. There can be
no assurance that the Company will be the successful bidder to obtain or retain
contracts that come up for competitive bidding. In addition, some of the
Company's contracts may be terminated by the customer before the end of the
contract term. Municipalities in Washington may by law annex unincorporated
territory, which would remove such territory from the area covered by G
certificates issued by the Washington Utilities and Transportation Commission.
Such annexation could reduce the areas covered by the Company's G certificates
and subject more of the Company's Washington operations to competitive bidding
in the future. Moreover, the laws governing G Certificates could be amended or
repealed by legislative action, which action could have a material adverse
effect on the Company. See "Business -- G Certificates." The Company's inability
to replace revenues from contracts lost through competitive bidding or early
termination or the renegotiation of existing contracts with other revenues
within a reasonable time period could have a material adverse effect on the
Company's business, financial condition and results of operations.
    
 
     Intense competition exists not only to provide services to customers but
also to acquire other businesses within each market. Other companies have
adopted or should be expected to adopt the Company's strategy of acquiring and
consolidating regional and local businesses to develop a national presence.
Increasing consolidation in the solid waste services industry is expected to
increase competitive pressures. See "Business -- Competition."

     Potential Inability to Finance the Company's Potential Growth. The Company
anticipates that any future business acquisitions will be financed through cash
from operations, borrowings under its bank line of credit, the issuance of
shares of the Company's Common Stock and/or seller financing. If acquisition
candidates are unwilling to accept, or the Company is unwilling to issue, shares
of the Company's Common Stock as part of the consideration for such
acquisitions, the Company may be required to use more of its available cash
resources or borrowings under its credit facility to fund such acquisitions. To
the extent that cash from operations and borrowings under the Company's credit
facility are insufficient to fund acquisitions, the Company will require
additional equity and/or debt financing. Additionally, growth through the
development or acquisition of new landfills, transfer stations and other
facilities, as well as the ongoing maintenance of such landfills, transfer
stations or other facilities, may require substantial capital expenditures.
There can be no assurance that the Company will have sufficient existing capital
resources or be able to raise sufficient additional capital resources on terms
satisfactory to the Company to meet any or all of the foregoing capital
requirements.
 
     The terms of the Company's credit facility require the Company to obtain
the consent of the lending banks prior to consummating acquisitions of other
businesses for cash consideration (including all liabilities assumed) in excess
of $3.0 million. In addition, the Company may not incur aggregate indebtedness
greater than $250,000 to sellers in acquisition transactions without its
lenders' consent. The Company's inability to obtain such consent could prevent
the Company from completing certain acquisitions, which could inhibit the
Company's ability to execute its growth strategy. Furthermore, the Company's
credit facility contains various financial covenants predicated on the Company's
current and projected financial condition following completion of an
acquisition. If the Company is unable to satisfy these financial covenants on a
pro forma basis following completion of an acquisition, it would be unable to
complete the acquisition without a waiver from its lending banks. Whether or not
a waiver is needed, if the results of the Company's future operations differ
materially from those that are anticipated, the Company may no longer be able to
comply with the covenants in the credit facility. The Company's failure to
comply with such covenants may result in a default under the credit facility,
which could result in acceleration of the date for repayment of debt incurred
under the credit facility and would have a material adverse effect on the
Company's business, financial condition and results of operations. See "Use of
Proceeds," "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources" and Note 5 of Notes to
the Company's Financial Statements.
 
     Dependence on Management. The Company depends significantly on the services
of the members of its senior management team, the loss of any of whom may have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company currently maintains "key man" life insurance
with respect to Ronald J. Mittelstaedt, its President, Chief Executive Officer
and Chairman, in the amount of $3.0 million. See "Management." Key members of
the Company's management have entered into employment agreements with the
Company with terms ranging from three to five years. See
"Management -- Employment Agreements." No assurance can be given that these
agreements would be enforceable by the Company.
 
   
     Geographic Concentration. The Company's operations and customers are
located in Washington, California, Idaho, Wyoming and South Dakota, and the
Company expects to focus its operations on the Western U.S. for at least the
foreseeable future. As of March 31, 1998, approximately 74% of the Company's
total annualized revenues were derived from customers located in Washington.
Therefore, the Company's business, financial condition and results of operations
are susceptible to downturns in the general economy in the Western U.S.,
particularly in Washington, and other factors affecting the region, such as
state regulations affecting the solid waste services industry and severe weather
conditions. In addition, the costs and time involved in permitting, and the
scarcity of, available landfills in the Western U.S. could make it difficult for
the Company to expand vertically in those markets. There can be no assurance
that the Company will complete a sufficient number of acquisitions in other
markets to lessen its geographic concentration. See "Business -- Strategy."
    
 
                                       10
<PAGE>   12
 
     Seasonality of Business. Based on historic trends experienced by the
businesses acquired by the Company, the Company's results of operations will
vary seasonally, with revenues typically lowest in the first quarter of the
year, higher in the second and third quarters, and lower in the fourth quarter
than in the second and third quarters. This seasonality reflects the lower
volume of solid waste generated during the late fall, winter and early spring
months, resulting from decreased solid waste volume relating to construction and
demolition activities during the winter months in the Western U.S. In addition,
certain of the Company's operating costs should be generally higher in the
winter months, because adverse winter weather conditions slow waste collection
activities, resulting in higher labor costs, and greater precipitation increases
the weight of collected waste, resulting in higher disposal costs, which are
calculated on a per ton basis. Because a majority of the Company's operating
expenses are expected to remain fairly constant throughout the fiscal year,
operating income should be expected to be generally lower in the winter months.
There can be no assurance that future seasonal and quarterly fluctuations will
not have a material adverse effect on the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
   
     Government Regulation. The Company is subject to extensive and evolving
environmental laws and regulations, the enforcement of which has become
increasingly stringent in recent years as a result of greater public interest in
protecting the environment. These laws and regulations impose substantial costs
on the Company and affect the Company's business in many ways, including as set
forth below and under "Business -- Regulation." In addition, the nature and
extent to which federal, state and local governments grant rights to and impose
restrictions on companies in the solid waste services industry is inherently
subject to change, and such changes could have a material adverse effect on the
Company.
    
 
     If the Company implements its strategy for landfill ownership and
operation, it will be necessary to obtain and maintain in effect one or more
licenses or permits, as well as zoning, environmental and/or other land use
approvals. These licenses or permits and approvals are difficult and time-
consuming to obtain and renew and are frequently subject to opposition by
various elected officials or citizens' groups. See "Business -- Legal
Proceedings." 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 ownership or operation (including capacity increases) of any future
landfill activities engaged in by the Company, and the failure by the Company to
obtain or maintain in effect a permit or approval significant to its landfill
business could have a material adverse effect on the Company's results of
operations and financial condition.
 
     The design, operation and closure of landfills is extensively regulated.
These regulations include, among others, the regulations ("Subtitle D
Regulations") establishing minimum federal requirements adopted by the U.S.
Environmental Protection Agency (the "EPA") in October 1991 under Subtitle D of
the Resource Conservation and Recovery Act of 1976 ("RCRA"). Failure to comply
with these regulations could require the Company to undertake investigatory or
remedial activities, to curtail operations or to close a landfill temporarily or
permanently. Future changes to these regulations may require the Company to
modify, supplement or replace equipment or facilities at costs that may be
substantial. The failure of regulatory agencies to enforce these regulations
vigorously or consistently may give an advantage to competitors of the Company
whose facilities do not comply with the Subtitle D Regulations or their state
counterparts. The Company's financial obligations arising from any failure to
comply with these regulations could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     Companies in the solid waste services business, including the Company, are
frequently subject in the normal course of business to judicial and
administrative proceedings involving federal, state or local agencies or
citizens' groups. Governmental agencies may seek to impose fines or penalties on
the Company or to revoke or deny renewal of the Company's operating permits,
franchises or
 
                                       11
<PAGE>   13
 
licenses for violations or alleged violations of environmental laws or
regulations or require the Company to make expenditures to remediate potential
environmental problems relating to waste disposed of or stored by the Company or
its predecessors, or resulting from its or its predecessors' transportation and
collection operations. The Company may also be subject to actions brought by
individuals or community groups in connection with the permitting, franchising
or licensing of its operations, any alleged violation of such permits,
franchises or licenses or other matters. Any adverse outcome in these
proceedings could have a material adverse effect on the Company's business,
financial condition and results of operations and may subject the Company to
adverse publicity. See "Potential Environmental Liability" below and
"Business -- Legal Proceedings."
 
     Potential Environmental Liability. The Company is subject to liability for
any environmental damage that its solid waste facilities may cause, including
damage to neighboring landowners or residents, particularly as a result of the
contamination of soil, groundwater or surface water, and especially drinking
water. The Company's potential liability includes damage resulting from
conditions existing prior to the acquisition of such facilities by the Company.
The Company may also be subject to liability for any off-site environmental
contamination caused by pollutants or hazardous substances whose transportation,
treatment or disposal was arranged by the Company or its predecessors. Any
substantial liability for environmental damage incurred by the Company could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business -- Regulation."
 
     The Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA" or "Superfund"), imposes strict, joint and several
liability on the present owners and operators of facilities from which a release
of hazardous substances into the environment has occurred, as well as any party
that owned or operated the facility at the time of disposal of the hazardous
substances, regardless of when the hazardous substance was first detected.
CERCLA defines the term "hazardous substances" very broadly to include more than
700 substances that are specified under RCRA, have specific hazardous
characteristics defined under RCRA or are regulated under any of several other
statutes.
 
     Similar liability is imposed on the generators of waste that contains
hazardous substances and on hazardous substance transporters that select the
treatment, storage or disposal site. All such persons, who are referred to as
potentially responsible parties ("PRPs"), generally are jointly and severally
liable for the expense of waste site investigation, waste site cleanup costs and
natural resource damages, regardless of whether they exercised due care and
complied with all relevant laws and regulations. These costs can be very
substantial. Furthermore, such liability can be based on the existence of even
very small amounts of hazardous substances; unlike most of the other statutes
that regulate hazardous substances, CERCLA does not require any minimum volume
or concentration of a hazardous substance to be present before imposing
liability. It is likely that hazardous substances have in the past come to be
located in landfills with which the Company is or will become associated. If any
of the Company's sites or operations ever experiences environmental problems,
the Company could be subject to substantial liability, which could have a
material adverse effect on its business, financial condition and results of
operations. The Company has not been named as a PRP in any action brought under
CERCLA. See "Business -- Regulation."
 
     With respect to each business that the Company acquires or has acquired,
there may be liabilities that the Company fails or is unable to discover,
including liabilities arising from noncompliance with environmental laws by
prior owners, and for which the Company, as a successor owner, may be legally
responsible. Representations, warranties and indemnities from the sellers of
such businesses, if obtained and if legally enforceable, may not cover fully the
resulting environmental liabilities, because of their limited scope, amount or
duration, the financial limitations of the warrantor or indemnitor or other
reasons. Certain environmental liabilities, even though expressly not assumed by
the Company, may nonetheless be imposed on the Company under certain legal
theories of successor liability, particularly under CERCLA. The Company's
insurance program does not cover liabilities associated with any environmental
cleanup or
 
                                       12
<PAGE>   14
 
remediation of the Company's own sites. An uninsured claim against the Company,
if successful and of sufficient magnitude, could have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business -- Acquisition Program."
 
   
     Limitations on Landfill Permitting and Expansion. The Company currently
owns no landfills and operates only one landfill. The Company's ability to meet
its growth objectives may depend in part, however, on its ability to acquire,
lease and expand landfills and develop new landfill sites. As of May 15, 1998,
the estimated total remaining permitted disposal capacity of the Fairmead
Landfill in Madera County, California operated by the Company was approximately
600,000 tons, with approximately 3.5 million additional tons of disposal
capacity in various stages of permitting. There can be no assurance that the
Company will be successful in obtaining new landfill sites or expanding the
permitted capacity of the Fairmead Landfill once its remaining permitted
disposal capacity has been consumed.
    
 
     In some areas in which the Company operates, suitable land for new sites or
expansion of existing landfill sites may be unavailable. Landfills in states in
which the Company operates are subject to state regulations and practices that
generally require operating permits to be renewed at least every five years. The
process of obtaining required permits and approvals to build, operate and expand
solid waste management facilities, including landfills and transfer stations,
has become increasingly difficult and expensive, often taking several years,
requiring numerous hearings and compliance with zoning, environmental and other
requirements and often subject to resistance from citizen, public interest or
other groups. There can be no assurance that the Company will succeed in
obtaining or maintaining the permits it requires to expand or that such permits
will not contain burdensome terms and conditions. Even when granted, final
permits to expand are often not approved until the remaining permitted disposal
capacity of a landfill is very low. Furthermore, local laws and ordinances also
may affect the Company's ability to obtain permits to expand landfills. If the
Company were to exhaust its permitted capacity at a landfill, its ability to
expand internally would be limited, and the Company could be required to cap and
close that landfill and forced to dispose of collected waste at more distant
landfills or at landfills operated by its competitors. The resulting increased
costs would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Services -- Landfills."
 
     Alternatives to Landfill Disposal; Waste Reduction Programs. Alternatives
to landfill disposal, such as recycling, composting and incineration, are
available in some areas in which the Company operates. In addition, state and
local authorities increasingly mandate recycling and waste reduction at the
source and prohibit the disposal of certain types of wastes, such as yard
wastes, at landfills. These developments may result in the volume of waste being
reduced in certain areas. For example, California has adopted plans that set
goals for percentages of certain solid waste items to be recycled, which are
being phased in over the next several years. Increased use of alternatives to
landfill disposal may have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     Potential Inadequacy of Accruals for Closure and Post-Closure
Costs. Although the Company currently owns no landfills and operates only one
landfill, it may own and/or operate additional landfills in the future. In such
case, the Company will have material financial obligations relating to closure
and post-closure costs of landfills and any disposal facilities that it owns or
operates. The Company will in the future provide accruals for future financial
obligations relating to closure and post-closure costs of its owned or operated
landfills (generally for a term of 30 years after final closure of a landfill),
based on engineering estimates of consumption of permitted landfill airspace
over the useful life of any such landfill. There can be no assurance that the
Company's financial obligations for closing or post-closing costs will not
exceed the amount accrued and reserved or amounts otherwise receivable pursuant
to funds or reserves established for such purpose. Such a circumstance could
have a material adverse effect on the Company's business, financial condition
and results of operation. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Services -- Landfills."
 
                                       13
<PAGE>   15
 
     Incurrence of Charges Related to Capitalized Expenditures. In accordance
with generally accepted accounting principles, the Company capitalizes certain
expenditures and advances relating to acquisitions, pending acquisitions and
landfill development 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 project that is
not expected to be completed successfully. Therefore, the Company may be
required to incur a charge against earnings in future periods, which charge,
depending on its magnitude, could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
   
     Potential Inability to Obtain Performance or Surety Bonds, Letters of
Credit or Insurance. Municipal solid waste services contracts and landfill
closure obligations may require performance or surety bonds, letters of credit,
or other means of financial assurance to secure contractual performance. Ten of
the Company's existing 34 solid waste collection and recycling contracts require
the Company to obtain performance bonds, which it has obtained. If the Company
in the future were unable to obtain performance or surety bonds or letters of
credit in sufficient amounts or at acceptable rates, it could be precluded from
entering into additional municipal solid waste services contracts or obtaining
or retaining landfill operating permits. Any future difficulty in obtaining
insurance could also impair the Company's ability to secure future contracts
conditioned on the contractor's having adequate insurance coverage. Accordingly,
the failure of the Company to obtain performance or surety bonds, letters of
credit or other means of financial assurance or to maintain adequate insurance
coverage could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Risk Management,
Insurance and Performance Bonds."
    
 
     Commodity Risk Upon Resale of Recyclables. The Company provides recycling
services to some of its customers. The sale prices of and demand for recyclable
waste products, particularly wastepaper, have been, and may continue to be,
volatile and subject to changing market conditions. Accordingly, the Company's
results of operations may be affected by changing resale prices or demand for
certain recyclable waste products, particularly wastepaper. These changes may
contribute to variability in the Company's period-to-period results of
operations. See "Business -- Services -- Recycling and Other Services."
 
     Potential Anti-Takeover Effect of Certain Charter and By-Law Provisions and
Delaware Law. The Company's Amended and Restated Certificate of Incorporation
(the "Restated Certificate of Incorporation") and Amended and Restated By-Laws
(the "Restated By-Laws") provide for the Company's Board of Directors to be
divided into three classes of directors serving staggered three-year terms. As a
result, beginning in 1998, approximately one-third of the Company's Board will
be elected each year. The classified Board is designed to ensure continuity and
stability in the Board's composition and policies in the event of a hostile
takeover attempt or proxy contest. The classification of the Board would extend
the time required to effect any changes in control of the Board and may
discourage any hostile takeover bid for the Company. The classified Board may
also make the removal of the Company's incumbent management more difficult, even
if such removal would be beneficial to stockholders generally, and therefore may
discourage certain tender offers.
 
     The authorized capital of the Company includes 10,000,000 shares of "blank
check" Preferred Stock, of which 2,500,000 shares have been authorized and
2,499,998 shares have been issued as Series A Preferred Stock. All outstanding
shares of Series A Preferred Stock automatically convert into shares of Common
Stock on a one-for-one basis upon the closing of this offering. The Board of
Directors has the authority to issue shares of Preferred Stock and to determine
the price, designation, rights, preferences, privileges, restrictions and
conditions, including voting and dividend rights, of these shares of Preferred
Stock without any further vote or action by the
                                       14
<PAGE>   16
 
stockholders. The rights of the holders of Common Stock will be subject to, and
may be adversely affected by, the rights of holders of any Preferred Stock that
may be issued in the future. The issuance of Preferred Stock, while providing
desirable flexibility in connection with possible acquisitions and other
corporate purposes, could make it more difficult for a third party to acquire a
majority of the outstanding voting stock of the Company. The Company has no
present plans to issue any additional Preferred Stock. See "Description of
Capital Stock."
 
     The Company is subject to the anti-takeover provisions of Section 203 of
the Delaware General Corporation Law, which, subject to certain exceptions,
prohibits the Company from engaging in a "business combination" with an
"interested stockholder" for a period of three years following the time that
such stockholder became an interested stockholder. The application of Section
203 also could have the effect of delaying or preventing a change of control of
the Company. These provisions, and provisions of the Restated Certificate of
Incorporation and Restated By-Laws, may deter hostile takeovers or delay or
prevent changes in control or management of the Company, including transactions
in which stockholders might otherwise receive a premium for their shares over
then current market prices. In addition, these provisions may limit the ability
of stockholders to approve transactions that they may deem to be in their best
interests. See "Description of Capital Stock -- Preferred Stock" and "-- Certain
Statutory, Charter and By-Law Provisions."
 
   
     Shares Eligible for Future Sale; Registration Rights. The sale of
substantial amounts of the Company's Common Stock in the public market following
this offering (including shares issued on the exercise of outstanding warrants
and stock options), or the perception that such sales could occur, could
adversely affect prevailing market prices of the Company's Common Stock. All of
the shares offered hereby will be freely saleable in the public market after
completion of this offering, unless acquired by affiliates of the Company. The
remaining 5,932,724 shares of Common Stock held by existing stockholders on
completion of this offering will be "restricted securities," as that term is
defined in Rule 144 under the Securities Act. Restricted securities may be sold
in the public market only if they are registered or if they qualify for an
exemption from registration under Rule 144 or 701 promulgated under the
Securities Act. All of the shares outstanding prior to completion of this
offering are subject to contractual restrictions that prohibit the stockholders
from selling or otherwise disposing of such shares for a period of 180 days
after the date of this Prospectus without the prior written consent of BT Alex.
Brown Incorporated. The Company has also agreed not to sell any shares of Common
Stock for 180 days after the date of this Prospectus without the prior written
consent of BT Alex. Brown Incorporated, except as consideration for business
acquisitions, upon the exercise of currently outstanding stock options or
warrants, or upon the issuance of options to employees, consultants and
directors under the Company's 1997 Stock Option Plan and the exercise of such
options. After this 180-day period expires, 4,749,998 of the shares of Common
Stock that are either currently outstanding or will be outstanding on conversion
of the currently outstanding Series A Preferred Stock will be eligible for
resale in the public market under Rule 144 promulgated under the Securities Act.
An additional 1,000,000 of the currently outstanding shares of Common Stock will
become saleable in the public market in February 1999, an additional 132,726 of
the currently outstanding shares will become saleable in the public market later
in 1999, and an additional 50,000 of the currently outstanding shares of Common
Stock will become saleable in the public market ratably over three years, in
each case subject to the restrictions of Rule 144. In addition, certain
stockholders, who after the closing of this offering will own approximately
5,849,998 shares of Common Stock, have the right for the five years after the
closing of this offering, subject to certain conditions, to include their shares
in future registration statements relating to the Company's securities and to
cause the Company to register certain shares of Common Stock owned by them. See
"Shares Eligible for Future Sale."
    
 
     After the completion of this offering, the Company intends to file a
registration statement under the Securities Act to register all shares issuable
on exercise of stock options or other awards granted or to be granted under its
existing stock plan. See "Management -- 1997 Stock Option Plan." After the
filing of such registration statement and subject to certain restrictions under
Rule 144, those shares will be freely saleable in the public market immediately
following exercise of such options.
 
                                       15
<PAGE>   17
 
     The Company currently intends to file a shelf registration statement
covering up to an additional 3,000,000 shares of Common Stock under the
Securities Act for its use in connection with future acquisitions. Such shares,
when issued, could be freely saleable in the public market 180 days after the
date of this Prospectus, or earlier on prior written approval of BT Alex. Brown
Incorporated by persons not affiliated with the Company, unless the Company
contractually restricts their resale. See "Shares Eligible for Future Sale" and
"Underwriting."
 
     No Prior Public Market; Fluctuations in Quarterly Results; Potential Stock
Price Volatility. Prior to this offering, there has been no public market for
the Company's Common Stock, and there can be no assurance that an active trading
market will develop or be sustained after completion of this offering. The
initial public offering price will be determined through negotiations between
the Company and the representatives of the Underwriters based on several
factors, and may not be indicative of the market price of the Common Stock after
completion of this offering. See "Underwriting." The Company believes that
period-to-period comparisons of its operating results should not be relied upon
as an indication of future performance. Due to a variety of factors, including
general economic conditions, government regulatory action, acquisitions, capital
expenditures and other costs related to the expansion of operations and
services, pricing changes and adverse weather conditions, it is possible that in
some future quarter, the Company's operating results will be below the
expectations of securities analysts and investors. In such event, the price of
the Company's Common Stock would likely be materially adversely affected. The
price of the Company's Common Stock may be highly volatile and is likely to be
affected by the foregoing and other factors. In addition, the stock market has
from time to time experienced significant price and volume fluctuations that
have often been unrelated to the operating performance of companies whose
securities are publicly traded. These broad market fluctuations, however, may
adversely affect the market price of the publicly traded securities of such
companies, including the Company's Common Stock. In the past, following periods
of volatility in the market price of a company's securities, securities class
action litigation has often been commenced against such company. There can be no
assurance that such litigation will not occur in the future with respect to the
Company. Litigation could result in substantial costs and divert management's
attention and resources, which could have a material adverse effect on the
Company's business, financial condition and results of operations. Any adverse
determination in any such litigation could also subject the Company to
significant liabilities.
 
     Immediate and Substantial Dilution. Purchasers of shares of Common Stock in
this offering will incur an immediate and substantial dilution in the net
tangible book value per share of the Common Stock from the initial public
offering price. Investors will experience additional dilution as a result of
Common Stock being issued upon the exercise of outstanding stock options and
warrants. To implement its acquisition strategy, the Company intends to register
up to 3,000,000 additional shares of Common Stock for issuance in connection
with future acquisitions. If shares of Common Stock are issued in connection
with future acquisitions, purchasers of shares of Common Stock in this offering
may experience additional dilution. See "Dilution" and "Shares Eligible for
Future Sale."
 
     No Dividends. The Company does not intend to pay cash dividends on the
Common Stock in the foreseeable future and anticipates that future earnings will
be retained to finance future operations and expansion. In addition, the terms
of the Company's credit facility prohibit the Company from paying dividends or
making other payments with respect to its Common Stock without the consent of
the lenders. See "Dividend Policy."
 
     Impact of the Year 2000. The Company will need to modify or replace
portions of its software so that its computer systems will function properly
with respect to dates in the year 2000 ("Year 2000") and thereafter. The Company
expects to complete those modifications and upgrades during 1999. The total Year
2000 project cost is estimated to be approximately $100,000. To date, the
Company has not incurred any costs related to the Year 2000 project. The Company
does not believe that its expenditures relating to the Year 2000 project will be
material. However, if the required Year 2000 modifications and conversions are
not made or are not completed in a timely manner, the Year 2000 issue could
materially affect the Company's operations.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered hereby (after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company) are
estimated to be $19.3 million ($22.3 million if the Underwriters' overallotment
option is exercised in full), assuming an initial public offering price of
$11.00 per share.
    
 
   
     The Company intends to use the net proceeds to reduce outstanding
indebtedness under its credit facility with BankBoston, N.A. Approximately $20.1
million was outstanding under that facility as of May 15, 1998. The Company's
credit facility provides for borrowing capacity of up to $25.0 million,
presently bears interest based on either an adjusted prime rate or the
Eurodollar rate plus 2.0% to 2.75% per annum (the applicable rate was 8.4% as of
the date of this Prospectus) and will mature on January 30, 2001. The credit
facility was obtained primarily to fund acquisitions and to refinance debt
incurred in connection with the acquisition the Company completed in September
1997. The terms of the credit facility permit the Company to redraw on the
credit facility as needed for future acquisitions and capital expenditures
(subject to certain restrictions) and general corporate purposes. On April 21,
1998, the Company received a preliminary letter of commitment from its lender to
amend and increase its credit facility. The amendment is contingent on the
completion of this offering and will, among other things, increase the Company's
borrowing capacity to $60.0 million, modify certain covenants and lower the
Company's borrowing costs.
    
 
   
     The balance of the estimated net offering proceeds, if any, will be used
for acquisitions, capital expenditures and working capital. Pending specific
application of the net proceeds, the Company intends to invest unused net
proceeds in short-term, interest-bearing securities. The Company continually
evaluates potential acquisition candidates and intends to continue to pursue
acquisition opportunities that may become available.
    
 
                                DIVIDEND POLICY
 
     The Company has never paid cash dividends on its Common Stock, and the
Company does not anticipate paying any cash dividends on the Common Stock in the
foreseeable future. The Company intends to retain all earnings for use in the
operation and expansion of its business. In addition, the Company's credit
facility contains restrictions on the payment of cash dividends. The Series A
Preferred Stock provides for cumulative dividends, which the Company intends to
pay in cash prior to the conversion of the Series A Preferred Stock into Common
Stock upon consummation of this offering.

                                 CAPITALIZATION
 
   
     The following table sets forth, as of March 31, 1998, (i) the long-term
debt and capitalization of the Company on an historical basis, and (ii) such
long-term debt and capitalization as adjusted to give effect to the sale by the
Company of the 2,000,000 shares offered hereby, at an assumed initial public
offering price of $11.00 per share, after deducting underwriting discounts and
commissions and estimated offering expenses, after conversion of all outstanding
shares of redeemable Common Stock and redeemable convertible Preferred Stock
into 1,000,000 and 2,499,998 shares of Common Stock, respectively, after payment
of $123,000 in accumulated Preferred Stock dividends, and after the application
of a portion of the estimated net offering proceeds to repay indebtedness as
described under "Use of Proceeds." This table should be read in conjunction with
the Company's Financial Statements and Notes thereto and the Unaudited Pro Forma
Financial Statements and Notes thereto, which are included elsewhere in this
Prospectus. See "Description of Capital Stock."

                                    DILUTION
 
     The negative net tangible book value of the Company's Common Stock as of
March 31, 1998, was $(9.0) million, or $(1.54) per share. Net tangible book
value per share represents the amount of the Company's total tangible assets,
less its total liabilities (excluding redeemable Common Stock and redeemable
convertible Preferred Stock), divided by the total number of shares of Common
and Preferred Stock (including redeemable stock) outstanding immediately prior
to this offering.
 
   
     After giving effect to the sale by the Company of 2,000,000 shares of
Common Stock in this offering at an assumed public offering price of $11.00 per
share (and after deduction of the underwriting discounts and commissions and
estimated offering expenses), the Company's net tangible book value as of March
31, 1998, would have been approximately $10.2 million, or $1.30 per share of
Common Stock. This represents an immediate increase in net tangible book value
of approximately $2.84 per share to existing stockholders and an immediate
dilution of net tangible book value of approximately $9.70 per share to new
investors purchasing Common Stock in this offering, as illustrated in the
following table:

     As of March 31, 1998, the Company had outstanding stock options and
warrants exercisable for 2,276,300 shares of Common Stock at a weighted average
exercise price of $3.68 per share. If these options and warrants are exercised,
further dilution to new investors will occur. The Company may also issue
additional shares to effect future business acquisitions or upon exercise of
stock options granted in the future or other equity awards, which could result
in additional dilution to then existing stockholders. See
"Management -- Executive Compensation -- Stock Options and Warrants."

predecessor operations at various times during 1995 and 1996, and prior to being
acquired by BFI, the predecessors operated as separate stand-alone businesses.
The selected financial information of the Company's predecessors as of December
31, 1996, for the nine months ended September 30, 1997, and for the years ended

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Unaudited
Pro Forma Financial Statements and Notes thereto, the audited and unaudited
Financial Statements and Notes thereto of the Company and its predecessors,
Madera's audited Financial Statements and Notes thereto, and other financial
information included elsewhere in this Prospectus. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results may differ materially from those discussed in the forward-looking
statements as a result of various factors, including without limitation those
set forth in "Risk Factors" and the matters set forth in this Prospectus
generally.
 
OVERVIEW
 
   
     Waste Connections is a regional, integrated solid waste services company
that provides solid waste collection, transfer, disposal and recycling services
in secondary markets of the Western U.S. As of May 15, 1998, the Company served
more than 139,000 commercial, industrial and residential customers in
Washington, California, Idaho, Wyoming and South Dakota. The Company currently
owns nine collection operations and operates three transfer stations, one
Subtitle D landfill and one recycling facility.
    
 
   
     The Company generally intends to pursue an acquisition-based growth
strategy and has acquired ten companies since its inception in September 1997.
All of these acquisitions were accounted for as purchases. Accordingly, the
results of operations of these acquired businesses have been included in the
Company's financial statements only from the respective dates of acquisition.
The Company anticipates that a substantial part of its future growth will come
from acquiring additional solid waste collection, transfer and disposal
businesses and, therefore, it is expected that additional acquisitions could
continue to affect period-to-period comparisons of the Company's operating
results. In connection with the Company's growth strategy, the Company expects
to invest in collection vehicles and equipment, maintenance of existing
equipment, and management information systems, which should enable the Company
to expand internally and through acquisitions based on its existing
infrastructure. The Company anticipates that any future business acquisitions
will be financed through cash from operations, borrowings under its bank line of
credit, the issuance of shares of the Company's Common Stock and/or seller
financing.
    
 
     In September 1997, the Company joined with two other parties to bid on
certain solid waste and recycling businesses offered for sale by BFI. The
Company acquired the stock of Browning-Ferris Industries of Washington, Inc., a
provider of solid waste services to more than 78,000 customers through three
municipal contracts and one G certificate in and around Clark County,
Washington, and the stock of its subsidiary, Fibres International, Inc., a
provider of solid waste services to more than 24,000 customers through eight
municipal contracts and one G certificate in King and Snohomish Counties,
Washington. The acquired companies subsequently changed their names to Waste
Connections of Washington, Inc. and Waste Connections International, Inc.,
respectively. The two other parties acquired selected BFI solid waste collection
and transportation assets and operations in Idaho, and BFI's recycling assets
and operations in Washington, Idaho and Oklahoma.
 
     On January 30, 1998, the Company acquired the stock of Waste Connections of
Idaho, Inc., a provider of solid waste collection services to more than 10,000
customers in and around Idaho Falls and Pocatello, Idaho through subscription
agreements with residential customers and seven municipal contracts. Waste
Connections of Idaho, Inc., was formed in September 1997 by affiliates of the
Company for the purpose of acquiring certain assets of Browing-Ferris Industries
of Idaho, Inc.
 
     Effective February 1, 1998, the Company acquired Madera, an integrated
solid waste services company operating in north central California, with 1997
revenues of approximately $7.8 million. In connection with the Madera
acquisition, the Company acquired one franchise agreement and one municipal
contract, pursuant to which it serves more than 9,000 commercial, industrial and
                                       23
<PAGE>   25
 
residential customers, and agreements to operate two transfer stations, one
Subtitle D landfill and one recycling facility.
 
     Effective March 1, 1998, the Company acquired certain solid waste
collection assets from Hunter Enterprises, Inc., a solid waste services company
located in eastern Idaho. These assets "tuck in" to the Company's Idaho
operations and serve approximately 2,800 residential and commercial customers.
 
     On April 8, 1998, the Company acquired solid waste collection assets from
A-1 Disposal, Inc. and Jesse's Disposal, both operating in northeastern Wyoming,
and together serving approximately 2,300 residential and commercial customers.
 
   
     On May 8, 1998, the Company acquired Sowers' Sanitation, Inc. and Sunshine
Sanitation Incorporated, providers of solid waste and recyclables collection
services to an aggregate of more than 7,000 customers in western South Dakota.
    
 
   
     On May 11, 1998, the Company acquired T&T Disposal, Inc., a provider of
solid waste and recyclables collection services to more than 500 customers in
eastern Wyoming.
    
 
   
     The entities the Company acquired in September 1997 from various
subsidiaries of BFI are collectively referred to herein as the Company's
predecessors. BFI acquired the predecessor operations at various times during
1995 and 1996, and prior to being acquired by BFI, the predecessors operated as
separate stand-alone businesses.
    
 
GENERAL
 
     The Company's revenues are attributable primarily to fees charged to
customers for solid waste collection, transfer, disposal and recycling services.
The Company derives a substantial portion of its collection revenues from
commercial, industrial and residential services, which are frequently performed
under service agreements or pursuant to franchise agreements with counties or
municipal contracts. County franchise agreements and municipal contracts
generally last from one to ten years. The Company's existing franchise agreement
and all of its existing municipal contracts give the Company the exclusive right
to provide specified waste services in the specified territory during the
contract term. Such exclusive arrangements are awarded, at least initially, on a
competitive bid basis and thereafter on a bid or negotiated basis. Some of the
Company's residential collection services are also performed on a subscription
basis with individual households. A substantial portion of the Company's
collection business in Washington is performed under G certificates awarded by
the Washington Utilities and Transportation Commission, which grant the Company
collection rights in certain areas. These rights are generally perpetual and
exclusive. See "Business -- G Certificates." Contracts with counties and
municipalities and G certificates provide relatively consistent cash flow during
the term of the contracts. Because most residential customers on a subscription
basis are billed quarterly, subscription agreements also are a stable source of
revenues for the Company. The Company's collection business also generates
revenues from the sale of recyclable commodities.
 
     Transfer station and landfill customers are charged a tipping fee on a per
ton basis for disposing of their solid waste at the transfer stations and
disposal facility operated by the Company under contract with the County of
Madera. The majority of the Company's transfer and landfill customers are under
one to ten year disposal contracts, most of which provide for annual cost of
living increases.
 
     The Company's prices for its solid waste services are typically determined
by the collection frequency and level of service, route density, volume, weight
and type of waste collected, type of equipment and containers furnished, the
distance to the disposal or processing facility, the cost of disposal or
processing, and prices charged by competitors for similar services. The
Company's ability to pass on price increases is sometimes limited by the terms
of its contracts. Long-term solid waste
 
                                       24
<PAGE>   26
 
collection contracts typically contain a formula, generally based on a
predetermined published price index, for automatic adjustment of fees to cover
increases in some, but not all, operating costs.
 
     Costs of operations include labor, fuel, equipment maintenance and tipping
fees paid to third party disposal facilities, worker's compensation and vehicle
insurance, the cost of materials purchased to be recycled, third party
transportation expense, district and state taxes, host community fees and
royalties. The Company operates three transfer stations, which reduce the
Company's costs by improving its utilization of collection personnel and
equipment and by consolidating the waste stream to gain more favorable disposal
rates.
 
     Selling, general and administrative ("SG&A") expenses include management,
clerical and administrative compensation and overhead costs associated with the
Company's marketing and sales force, professional services and community
relations expense.
 
     Depreciation and amortization expense includes depreciation of fixed assets
over the estimated useful life of the assets using the straight line method and
the amortization of goodwill and other intangible assets using the straight line
method.
 
     The Company capitalizes certain third party expenditures related to pending
acquisitions or development projects, such as legal and engineering expenses.
Indirect acquisition costs, such as executive and corporate overhead, public
relations and other corporate services, are expensed as incurred. The Company's
policy is to charge against net income any unamortized capitalized expenditures
and advances (net of any portion thereof that the Company estimates to 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 project that is not successfully completed. At March 31,
1998, the Company had no such capitalized costs. The Company routinely evaluates
all capitalized costs, and expenses those related to projects the Company
believes are not likely to be successful.
 
     Because it does not currently own any landfills, the Company does not
accrue for estimated landfill closure and post-closure maintenance costs. Under
regulations pursuant to which the permit for the Fairmead Landfill was issued,
the Company and Madera County, as operator and owner, respectively, are jointly
liable for closure and post-closure liabilities with respect to the landfill.
The Company has not accrued for such liabilities because Madera County, as
required by state law, has established a special fund, into which a designated
portion of tipping fee surcharges are deposited, to pay such liabilities.
Consequently, management of the Company does not believe Madera had any
financial obligation for closure and post-closure costs for the Fairmead
Landfill as of March 31, 1998. The Company will have material financial
obligations relating to closure and post-closure costs of any disposal
facilities it may own or operate in the future, and in such case the Company
will provide accruals for future financial obligations relating to closure and
post-closure costs of its landfills (generally for a term of 30 years after
final closure of a landfill), based on engineering estimates of consumption of
permitted landfill airspace over the useful life of any such landfill.
 
BASIS OF PRESENTATION
 
     The entities the Company acquired in September 1997 from BFI are
collectively referred to herein as the Company's predecessors. BFI acquired the
predecessor operations at various times during 1995 and 1996, and prior to being
acquired by BFI, the predecessors operated as separate stand-alone businesses.
 
     During the periods in which the Company's predecessors operated as wholly
owned subsidiaries of BFI, they maintained intercompany accounts with BFI for
recording intercompany charges for costs and expenses, intercompany purchases of
equipment and additions under capital leases and intercompany transfers of cash,
among other transactions. It is not feasible to ascertain the amount of related
interest expense that would have been recorded in the historical financial
statements had the predecessors been operated as stand-alone entities. Charges
for interest expense
 
                                       25
<PAGE>   27
 
were allocated to the Company's predecessors by BFI as disclosed in the
statement of operations data. The interest expense allocations from BFI are
based on formulas that do not necessarily correspond to the balances in the
related intercompany accounts. Moreover, the financial position and results of
operations of the predecessors during this period may not necessarily be
indicative of the financial position or results of operations that would have
been realized had the predecessors been operated as stand-alone entities. For
the periods in which the predecessors operated as wholly owned subsidiaries of
BFI, the statements of operations include amounts allocated by BFI to the
predecessors for selling, general and administrative expenses based on certain
allocation methodologies.
 
     During the periods prior to their acquisition by BFI, the Company's
predecessors operated as separate stand-alone businesses. The acquisitions of
the predecessors by BFI were accounted for using the purchase method of
accounting, and the respective purchase prices were allocated to the fair values
of the assets acquired and liabilities assumed. Similarly, the Company's
acquisitions of the predecessors from BFI in September 1997 were accounted for
using the purchase method of accounting, and the purchase price was allocated to
the fair value of the assets acquired and liabilities assumed. Consequently, the
amounts of depreciation and amortization included in the statements of
operations for the periods presented reflect the changes in basis of the
underlying assets that were made as a result of the changes in ownership that
occurred during the periods presented. In addition, because the predecessor
companies operated independently and were not under common control or management
during these periods, and because different tax strategies may have influenced
their results of operations, the data may not be comparable to or indicative of
their operating results after their acquisition by BFI.

     The Disposal Group Combined consists of three entities that were under
common control prior to their acquisition by BFI: Diamond Fab and Welding
Service, Inc., Buchmann Sanitary Service, Inc., and The Disposal Group.
 
     Due to the fact that the predecessor operations existed for different
periods, year-to-year comparisons are not meaningful and therefore discussions
of SG&A, depreciation and amortization and interest expense have not been
included in this Prospectus.
 
Waste Connections, Inc. -- Three Months Ended March 31, 1998 vs. Predecessors
Combined -- Three Months Ended March 31, 1997
 
     Revenue. Total revenues increased $1.9 million, or 33.5%, to $7.6 million
in 1998 from $5.7 million in 1997. The increase was primarily attributable to
the inclusion of two months of the Idaho operations acquired January 30, 1998
and the Madera operations acquired February 1, 1998 and growth in the base
business.
 
     Cost of Operations. Total cost of operations increased $723,000, or 15.5%,
to $5.4 million in 1998 from $4.7 million in 1997. The increase was primarily
attributable to the inclusion of two months of the Idaho operations and the
Madera operations and a decline in expenses in the existing business as a result
of cost reduction measures.

<PAGE>   29
 
1997 vs. 1996
 
     Revenue. The Company's total revenue for 1997 was $6.2 million. The total
revenue was attributable to the purchase of the Company's predecessors on
September 30, 1997. Revenues related to the Company's Predecessors Combined for
the nine months ended September 30, 1997 were $18.1 million. The Company's
Predecessors Combined for the period ended December 31, 1996 had revenues of
$13.4 million. The Disposal Group Combined had revenues of $8.7 million for the
period from January 1, 1996 to July 31, 1996. The monthly revenue run rate for
the Company and the Company's Predecessors Combined remained relatively
unchanged in 1997 versus 1996.
 
   
     Cost of Operations. The Company's total cost of operations in 1997 was $4.7
million, or 75.4% of revenue. The total cost of operations was attributable to
the purchase of the Company's predecessors on September 30, 1997. Cost of
operations of the Company's Predecessors Combined for the nine months ended
September 30, 1997 was $14.8 million, or 81.4% of revenue. The Company's
Predecessors Combined for the period ended December 31, 1996 had cost of
operations of $11.4 million, or 85.1% of revenue. The Disposal Group during the
period from January 1, 1996 to July 31, 1996 had cost of operations of $6.2
million, or 70.7% of revenue. The Company's cost of operations as a percentage
of revenue in 1997 declined from the Company's Predecessors Combined cost of
operations as a percentage of revenues in 1997 and 1996, due to price increases
in the fourth quarter of 1997 and operating cost savings in lease expense,
environmental accrual fee allocations from BFI, franchise fees and amortization
of loss contract accrual. The Company's Predecessors Combined cost of operations
as a percentage of revenue for the nine months ended September 30, 1997 declined
from 1996 due to the rollover effect of the acquisition of The Disposal Group in
1996, which had generally higher margins than the existing businesses.
    
 
1996 vs. 1995
 
     Revenue. The Company's Predecessors Combined total revenue for 1996 was
$13.4 million. The Disposal Group Combined total revenue for the period from
January 1, 1996 to July 31, 1996 was $8.7 million. The Company's Predecessors
Combined had revenues of $595,000 for the period ended December 31, 1995. The
Disposal Group Combined had revenues of $19.7 million for the year ended
December 31, 1995. Fibres International, Inc. had revenues of $7.3 million for
the period from January 1, 1995 to November 30, 1995. The monthly revenue run
rate for all of the Company's predecessors declined in 1996 from 1995 because of
the expiration of a municipal contract and a reduction in revenue from sales of
recyclable materials due to a reduction in prices of recyclable materials.
 
     Cost of Operations. The Company's Predecessors Combined total cost of
operations for 1996 was $11.4 million, or 85.1% of revenue, and The Disposal
Group Combined cost of operations for the period from January 1, 1996 to July
31, 1996 was $6.2 million, or 70.7% of revenue. Cost of operations of the
Company's Predecessors Combined for the period ended December 31, 1995 was
$527,000 or 88.6% of revenue. Cost of operations of The Disposal Group Combined
for the year ended December 31, 1995 was $16.4 million, or 83.4% of revenue.
Cost of operations of Fibres International, Inc. for the period from January 1,
1995 to November 30, 1995 was $5.7 million, or 77.0% of revenue. Changes in cost
of operations as a percentage of revenue were impacted by reductions in prices
of recyclable materials in 1996, offset by the expiration of a low margin
municipal contract in 1995.
 
Madera General
 
     Effective February 1, 1998, the Company acquired Madera, an integrated
solid waste services company operating in north central California, with 1997
revenues of approximately $7.8 million. In connection with the Madera
acquisition, the Company acquired one franchise agreement and one municipal
contract, pursuant to which it serves more than 9,000 commercial, industrial and
 
                                       28

(1) Prior to its acquisition by the Company, Madera operated under Subchapter S
    of the Internal Revenue Code and was not subject to corporate federal and
    state income tax. The Subchapter S election was terminated upon its
    acquisition by the Company. Had Madera filed federal and state income tax
    returns as a regular corporation for 1995, 1996 and 1997, income tax expense
    under the provisions of Financial Accounting Standards No. 109 would have
    been $30, $208 and $295, respectively. See Note 7 of Notes to Madera's
    Financial Statements included elsewhere herein.
 
Madera 1997 vs. 1996
 
     Revenue. Total revenues increased $75,000, or 1.0%, to $ 7.8 million in
1997 from $7.8 million in 1996. Exclusive of Madera's Professional Cleaning
Division ("PCD"), which ceased operations in July, 1997, revenues increased
$667,000, or 9.5%, to $7.7 million in 1997 from $7.0 million in 1996. This
increase was primarily attributable to increased landfill and collection volumes
resulting from existing franchise contracts, partially offset by a reduction in
landfill construction revenues.
 
     Cost of Operations. Total cost of operations decreased $223,000 to $5.3
million in 1997 from $5.5 million in 1996. The decrease was principally due to
the elimination of PCD, which was offset by increased operating cost associated
with increased volumes of waste from existing contracts. Cost of operations as a
percentage of revenues decreased to 67.4% from 70.9% in 1996. The percentage
decrease was primarily due to the elimination of PCD.
 
     SG&A. SG&A expenses increased approximately $72,000 to $1.0 million in 1997
from $969,000 in 1996. As a percentage of revenues, SG&A increased to 13.3% from
12.5% in 1996.
 
     Depreciation and Amortization. Depreciation and amortization expense
increased approximately $42,000 to $627,000 in 1997 from $585,000 in 1996.
Depreciation and amortization increased as a percentage of revenues to 8.0% from
7.5%.
 
                                       29
<PAGE>   31
 
     Interest Expense. Interest expense increased approximately $21,000 to
$280,000 in 1997 from approximately $259,000 in 1996. Interest expense as a
percentage of revenues increased to 3.6% in 1997 from 3.3% in 1996.
 
Madera 1996 vs. 1995
 
     Revenue. Total revenues increased $762,000, or 10.9%, to $7.8 million in
1996 from $7.0 million in 1995. Exclusive of PCD, revenues increased $508,000,
or 7.8%, to $7.0 million in 1996 from $6.5 million in 1995. This increase was
primarily attributable to increased landfill and collection volumes resulting
from existing franchise contracts and landfill construction revenues. This was
partially offset by decreased revenue from sales of recyclable materials due to
a decrease in the pricing associated with recyclable materials.
 
     Cost of Operations. Total cost of operations increased $224,000 to $5.5
million in 1996 from $5.3 million in 1995. The principal reason for the increase
was the start up of the PCD. Cost of operations as a percentage of revenues
decreased to 70.9% from 75.5% in 1996. The decrease was primarily due to the
increased volume of proportionately higher margin services.
 
     SG&A. SG&A expenses decreased approximately $27,000 to $969,000 in 1996
from $996,000 in 1995. As a percentage of revenues, SG&A decreased to 12.5% from
14.2% in 1996 due to improved economies of scale in the Company's landfill and
collections operations as a result of additional volumes from existing
customers.
 
     Depreciation and Amortization. Depreciation and amortization expense
increased approximately $118,000 to $585,000 in 1996 compared to $467,000 in
1995. Depreciation and amortization increased as a percentage of revenues to
7.5% in 1996 from 6.7% in 1995.
 
     Interest Expense. Interest expense increased approximately $22,000 to
$259,000 in 1996 from approximately $237,000 in 1995. Interest expense as a
percentage of revenues decreased to 3.3% in 1996 from 3.4% in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's business is capital intensive. The Company's capital
requirements include acquisitions and fixed asset purchases and are expected in
the future to include capital expenditures for landfill cell construction,
landfill development and landfill closure activities. The Company plans to meet
its capital needs through various financing sources, including internally
generated funds and debt and equity financing.
 
     As of March 31, 1998, the Company had working capital of $965,000,
including cash and cash equivalents of $2.4 million. The Company's strategy in
managing its working capital is generally to apply the cash generated from its
operations that remains available after satisfying its working capital and
capital expenditure requirements to reduce its indebtedness under its bank
revolving credit facility and to minimize its cash balances. The Company
finances its working capital requirements from internally generated funds and
bank borrowings.
 
   
     At inception, the Company sold 2,300,000 shares of Common Stock at $0.01
per share to its founders and 2,499,998 shares of Series A Preferred Stock at
$2.80 per share. As of May 15, 1998, the Company had sold or issued an
additional 1,132,726 shares of Common Stock at a weighted average value of $7.55
per share, and granted options and warrants to purchase 2,281,600 shares of
Common Stock at a weighted average exercise price of $3.69 per share. The
weighted average value at which shares were issued, and the weighted average
exercise price of the outstanding options and warrants, are significantly below
the assumed initial public offering price per share of Common Stock. The
Company's liquidity and capital resources would be greater if the Company had
sold shares at higher prices and issued options and warrants with higher
exercise prices. In addition, the Company's results of operations on a per share
basis would be more favorable if there were fewer shares outstanding. See "Risk
Factors -- Immediate and Substantial Dilution" and "Dilution."

     The Company has a $25.0 million revolving credit facility with BankBoston,
N.A., which is secured by all assets of the Company, including the Company's
interest in the equity securities of its subsidiaries. The credit facility
matures in 2001. It requires the Company to maintain certain financial ratios
and satisfy other predetermined requirements, such as minimum net worth, net
income and limits on capital expenditures. The credit facility also requires the
lenders' approval of acquisitions in certain circumstances. See "Risk
Factors -- Potential Inability to Finance the Company's Potential Growth." As of
March 31, 1998, an aggregate of approximately $17.0 million was outstanding
under the revolving line of credit. The interest rate on outstanding borrowings
under the BankBoston facility was 8.4% as of March 31, 1998. The Company has
obtained a preliminary letter of commitment from a syndicate of banks led by
BankBoston, contingent on the closing of this offering, to increase the credit
facility to $60.0 million. The credit facility will be used for: (i) refinancing
any existing debt; (ii) permitted acquisitions; (iii) capital expenditures; (iv)
working capital; (v) standby letters of credit; and (vi) general corporate
purposes. The facility will mature three years from the closing of this offering
and will be secured by substantially all the assets of the Company. The expanded
credit facility will bear interest at a rate per annum equal to, at the
Company's discretion, either: (i) the BankBoston Base Rate; or (ii) the
Eurodollar Rate plus applicable margin. The expanded credit facility is expected
to allow the Company to continue its acquisition-based growth strategy.
 
     For the three months ended March 31, 1998, net cash provided by operations
was approximately $713,000 and was primarily provided by net income for the
period. For the period from inception to December 31, 1997, net cash provided by
operations was $2.6 million. This was primarily the result of the net loss for
the period offset by non-cash charges for stock compensation expenses and cash
provided by changes in operating assets and liabilities. For example, accounts
payable increased as vendors extended credit to the Company. This was offset by
a decline in accounts receivable as the Company collected outstanding
receivables.
 
   
     For the three months ended March 31, 1998, net cash used in investing
activities was $9.2 million. Of this, $8.8 million was used to fund the cash
portion of the acquisitions of Madera, Waste Connections of Idaho and Hunter
Enterprises. The remaining cash was primarily invested in MIS systems, trucks
and containers. For the period from inception to December 31, 1997, net cash
used in investing activities was $11.9 million. Of this, $11.5 million was used
for the acquisition of the Company's predecessor operations from BFI. The
remainder was primarily invested in additional trucks, MIS systems and property
improvements.
    
 
   
     For the three months ended March 31, 1998, net cash provided by financing
activities was $10.0 million, which was provided by net borrowings under the
Company's various debt arrangements. For the period from inception to December
31, 1997, net cash provided by financing activities was $10.1 million, which was
provided by net borrowings of $3.2 million and sales of Preferred Stock for $7.0
million. At March 31, 1998, the Company had approximately $17.0 million of
long-term debt outstanding.
    
 
     The Company recorded an income tax benefit of $332,000 for the period from
inception (September 9, 1997) through December 31, 1997. The income tax benefit
was recognized because of the likelihood that it will be utilized through the
reversal of existing temporary differences.
 
     Capital expenditures for 1998 are currently expected to be approximately
$1.3 million, of which approximately $1.1 million is expected to be utilized for
vehicle and equipment additions and replacements. The Company intends to fund
its planned 1998 capital expenditures principally through internally generated
funds, proceeds from this offering and borrowings under existing credit
facilities. In addition, the Company anticipates that it may require substantial
additional capital expenditures to facilitate its growth strategy of acquiring
solid waste collection and disposal businesses. If the Company is successful in
acquiring landfill disposal facilities, the Company may also be required to make
significant expenditures to bring any such newly acquired disposal facilities
into compliance with applicable regulatory requirements, obtain permits for any
such
 
                                       31
<PAGE>   33
 
newly acquired disposal facilities or expand the available disposal capacity at
any such newly acquired disposal facilities. The amount of these expenditures
cannot be currently determined, because they will depend on the nature and
extent of any acquired landfill disposal facilities, the condition of any
facilities acquired and the permitted status of any acquired sites. The Company
believes that the credit facility, the funds expected to be generated from
operations, and the anticipated net proceeds of the offering will provide
adequate cash to fund the Company's working capital and other cash needs for the
foreseeable future.
 
   
     The Company derives a substantial portion of its revenues from exclusive
municipal contracts and franchise agreements. Its single largest contract, with
the City of Vancouver, accounted for approximately 18.1% of the Company's
revenues during the period from inception (September 9, 1997) through December
31, 1997, and 15.8% during the three months ended March 31, 1998. There are
approximately nine years remaining under that contract. No other single contract
or customer accounted for more than 7.1% of the Company's revenues during the
period from inception (September 9, 1997) through December 31, 1997, or 6.0%
during the three months ended March 31, 1998 or is material to its liquidity and
cash flow. The weighted average life, based on revenues, of the municipal
contracts and franchise agreement is approximately seven years.
    
 
INFLATION
 
     To date, inflation has not had a significant effect on the Company's
operations. Consistent with industry practice, many of the Company's contracts
provide for a pass-through of certain costs, including increases in landfill
tipping fees and, in some cases, fuel costs. The Company believes, therefore,
that it should be able to implement price increases to offset many cost
increases resulting from inflation. However, competitive pressures may require
the Company to absorb at least part of these cost increases, particularly during
periods of high inflation.
 
SEASONALITY
 
     Based on historic trends experienced by the businesses the Company has
acquired, the Company's results of operations should be expected to vary
seasonally, with revenues typically lowest in the first quarter, higher in the
second and third quarters and lower in the fourth quarter than in the second and
third quarters. This seasonality reflects the lower volume of solid waste
generated during the late fall, winter and early spring months, resulting from
decreased solid waste volume relating to construction and demolition activities
during the winter months in the Western U.S. In addition, certain of the
Company's operating costs should be expected to be generally higher in the
winter months; winter weather conditions slow waste collection activities,
resulting in higher labor costs, and greater precipitation increases the weight
of collected waste, resulting in higher disposal costs (which are calculated per
ton). Because a majority of the Company's operating expenses are expected to
remain fairly constant throughout the fiscal year, operating income should be
expected to be generally lower during the winter.
 
IMPACT OF YEAR 2000
 
     The Company will need to modify or replace portions of its software so that
its computer systems will function properly with respect to dates in the year
2000 ("Year 2000") and thereafter. The Company expects to complete those
modifications and upgrades during 1999. The total Year 2000 project cost is
estimated to be approximately $100,000, which includes approximately $40,000 for
the purchase of new software that will be capitalized and approximately $60,000
that will be expensed as incurred. To date, the Company has not incurred any
costs related to the Year 2000 project. The Company does not believe that its
expenditures relating to the Year 2000 project will be material. However, if the
required Year 2000 modifications and conversions are not made or are not
completed in a timely manner, the Year 2000 issue could materially affect the
Company's operations.

INTRODUCTION
 
   
     Waste Connections is a regional, integrated solid waste services company
that provides solid waste collection, transfer, disposal and recycling services
in secondary markets of the Western U.S. As of May 15, 1998, the Company served
more than 139,000 commercial, industrial and residential customers in
Washington, California, Idaho, Wyoming and South Dakota. The Company currently
owns nine collection operations and operates three transfer stations, one
Subtitle D landfill and one recycling facility.
    
 
   
     Waste Connections was founded in September 1997 to execute an
acquisition-based growth strategy in secondary markets of the Western U.S. The
Company has acquired ten solid waste services businesses since its formation and
has identified more than 300 independent operators of such businesses in the
states where is currently operates, many of which it believes may be suitable
for acquisition by the Company. In addition, the Company is currently assessing
potential acquisitions of solid waste services operations in Kansas, Montana,
Nebraska, Oklahoma, Oregon and Texas.
    
 
     The Company has targeted secondary markets in the Western U.S. because it
believes that: (i) a large number of independent solid waste services companies
suitable for acquisition by the Company are located in these markets; (ii) there
is less competition in these markets from large, well-capitalized solid waste
services companies; and (iii) these markets have strong projected economic and
population growth rates. In addition, the Company's senior management team has
extensive experience acquiring and operating solid waste services businesses in
the Western U.S.
 
INDUSTRY OVERVIEW
 
     According to Waste Age, an industry trade publication, the U.S. solid waste
services industry generated estimated revenues of $36.9 billion in 1997. The
solid waste services industry has undergone significant consolidation and
integration since 1990. The Company believes that, particularly in the Western
U.S., this consolidation and integration have been caused primarily by: (i)
stringent environmental regulation and enforcement, resulting in increased
capital requirements for collection companies and landfill operators; (ii) the
evolution of an industry competitive model that emphasizes integrating
collection and disposal capabilities; (iii) the ability of larger integrated
operators to achieve certain economies of scale; and (iv) the existence of a
regulatory framework that allows the acquisition of exclusive, long-term waste
collection rights through franchise agreements, municipal contracts and
governmental certificates.
 
     Increased Regulatory Impact. Stringent industry regulations, such as the
Subtitle D regulations, have resulted in rising operating and capital costs and
have accelerated consolidation and acquisition activities in the solid waste
collection and disposal industry. Many smaller industry participants have found
these costs difficult to bear and have decided to either close their operations
or sell them to larger operators. In addition, Subtitle D requires more
stringent engineering of solid waste landfills, including liners, leachate
collection and monitoring and gas collection and monitoring. These ongoing costs
are combined with increased financial reserve requirements for solid waste
landfill operators relating to closure and post-closure monitoring. As a result,
the number of solid waste landfills is declining while the size of solid waste
landfills is increasing.
 
     Integrating Collection and Disposal Operations. The evolution of the
industry competitive model is forcing operators to become more efficient by
establishing an integrated network of solid waste collection operations and
transfer stations, through which they secure solid waste streams for disposal.
Operators have adopted a variety of disposal strategies, including owning
landfills, establishing strategic relationships to secure access to landfills
and otherwise capturing significant waste stream volumes, to gain leverage in
negotiating lower landfill fees and securing long-term, most-favored-pricing
contracts with high capacity landfills.
 
                                       33
<PAGE>   35
 
     Economies of Scale. Larger integrated operators achieve economies of scale
through vertical integration of their operations. These integrated companies
have increased their acquisition activity to expand the breadth of services and
density in their market areas. Control of the waste stream in these market
areas, combined with access to significant financial resources to make
acquisitions, has allowed larger solid waste collection and disposal companies
to be more cost-effective and competitive.
 
     Despite the considerable consolidation and integration that has occurred in
the solid waste industry since 1990, the industry remains primarily regional in
nature and highly fragmented. Based on published industry sources, approximately
27% of the total revenues of the U.S. solid waste industry is accounted for by
more than 5,000 private, predominantly small, collection and disposal
businesses, approximately 41% by publicly traded solid waste companies and
approximately 32% by municipal governments that provide collection and disposal
services. The Company expects the current consolidation trends in the solid
waste industry to continue, because many independent landfill and collection
operators lack the capital resources, management skills and technical expertise
necessary both to operate in compliance with stringent environmental and other
governmental regulations and to compete with larger, more efficient integrated
operators. The Company believes that the fragmented nature of the industry
presents substantial consolidation and growth opportunities for companies with
disciplined acquisition programs, decentralized operating strategies and access
to financial resources.
 
     Regulatory Framework. In the Western U.S., waste collection services are
provided largely under three types of contractual arrangements: certificates or
permits, franchise agreements and municipal contracts. Certificates or permits,
such as G certificates awarded to waste collection service providers in
unincorporated areas and electing municipalities of Washington by the Washington
Utilities and Transportation Commission, typically grant the certificate holder
the right, which is generally perpetual and exclusive, to provide specific
residential, commercial and industrial waste services in a specified area. See
"G Certificates" below. Franchise agreements typically provide an exclusive
service period of five to ten years or longer and specify the service territory,
a broad range of services to be provided, and rates for the services. They also
often give the service provider a right of first refusal to extend the term of
the agreement. Municipal contracts typically provide a shorter service period
and a more limited scope of services than franchise agreements and generally
require competitive bidding at the end of the contract term. Unless customers
within the areas covered by certain permits or certificates (including G
certificates), franchise agreements and municipal contracts elect not to receive
any waste collection services, they are required to pay collection fees to the
company providing such services in their area.
 
     The Company operates one landfill and may acquire or operate others in the
future. The Company believes, however, that in those secondary markets of the
Western U.S. where waste collection services are provided under exclusive
certificates, franchises or contracts, or where waste disposal is municipally
funded or available from multiple sources, controlling the waste stream by
providing collection services under exclusive arrangements is often more
important to a waste services company's growth and profitability than owning or
operating landfills. Several other characteristics of secondary markets in the
Western U.S. limit the economic attractiveness of owning or operating landfills
in those markets. For example, certain state and local regulations in the
Western U.S. restrict the amount of waste that may be accepted from specific
geographic areas. In addition, the relatively expansive geographic area of many
western states increases the cost of interstate and long haul disposal, which
heightens the effects of state and local regulations limiting the type and
origin of waste that may be accepted at a landfill and makes it more difficult
for a landfill to achieve the disposal volume necessary to operate profitably,
given its capital and operating costs. The Company believes that significant
opportunities exist for a well-capitalized company operating in secondary
markets of the Western U.S., and that the highly fragmented nature of this
industry should allow the Company to consolidate existing solid waste services
businesses in this region.

STRATEGY
 
     The Company's objective is to build a leading integrated solid waste
services company in secondary markets of the Western U.S. The Company's strategy
for achieving this objective is to: (i) acquire collection, transfer, disposal
and recycling operations in new markets and through "tuck-in" acquisitions in
existing markets; (ii) secure additional franchises, municipal contracts and
governmental certificates; (iii) generate internal growth in existing markets by
increasing market penetration and adding services to its existing operations;
and (iv) enhance profitability by increasing operating efficiencies of existing
and acquired operations. The Company's ability to implement this strategy is
enhanced by the experience of the members of its senior management team and
their knowledge of and reputation in the solid waste services industry in the
Company's targeted markets. The Company intends to implement its strategy as
follows:
 
  Expansion Through Acquisitions
 
     The Company intends to expand significantly the scope of its operations by:
(i) acquiring solid waste collection, transfer, disposal and recycling
operations in new markets; and (ii) acquiring solid waste collection, transfer,
disposal and recycling operations in existing and adjacent markets through
"tuck-in" acquisitions.
 
   
     The Company intends to follow a regional expansion strategy by entering new
markets through acquisitions. An initial acquisition in a new market is used as
an operating base for the Company in that area. The Company then seeks to
strengthen the acquired operation's presence in that market by providing
additional services, adding new customers and making tuck-in acquisitions. The
Company can then broaden its regional presence by adding additional operations
in markets adjacent to the new location. The Company is currently examining
opportunities to expand its presence in the Western U.S. in states other than
Washington, California, Idaho, Wyoming and South Dakota and is assessing
potential acquisitions of solid waste services operations in Kansas, Montana,
Nebraska, Oklahoma, Oregon and Texas.
    
 
     The Company believes that numerous "tuck-in" acquisition opportunities
exist within its current and targeted market areas. For example, the Company has
identified more than 300 independent entities that provide collection and
disposal services in California, Washington and Idaho. The Company believes that
throughout the Western U.S., many independent entities are suitable for
acquisition by the Company and would provide the Company opportunities to
improve market share and route density.
 
  Franchise Agreements, Municipal Contracts and Governmental Certificates
 
     The Company intends to devote significant resources to securing additional
franchise agreements and municipal contracts through competitive bidding and
additional governmental certificates through the acquisition of other companies.
In bidding for franchises and municipal contracts and evaluating the acquisition
of companies holding governmental certificates, the Company's management team
draws on its experience in the waste industry and its knowledge of local service
areas in existing and target markets. The Company's district managers manage
relationships with local governmental officials within their respective service
areas, and sales representatives may be assigned to cover specific
municipalities. These personnel focus on maintaining, renewing and renegotiating
existing franchise agreements and municipal contracts and on securing additional
agreements, contracts and governmental certificates.
 
  Internal Growth
 
     To generate continued internal growth, the Company will focus on increasing
market penetration in its current and adjacent markets, soliciting new
commercial, industrial, and residential customers in markets where such
customers may elect whether or not to receive waste collection services,
marketing upgraded or additional services (such as compaction or automated
                                       35
<PAGE>   37
 
collection) to existing customers and, where appropriate, raising prices. Where
possible, the Company intends to leverage its franchise-based platforms to
expand its customer base beyond its exclusive market territories. As customers
are added in existing markets, the Company's revenue per routed truck increases,
which generally increases the Company's collection efficiencies and
profitability. In markets in which it has exclusive contracts, franchises and
certificates, the Company expects internal growth to at least track population
and business growth.
 
     The Company expects to use transfer stations as an important part of its
internal growth strategy, by extending the direct-haul reach of the Company and
linking disparate collection operations with Company-owned, operated or
contracted disposal capacity. The Company currently operates three transfer
stations. By operating transfer stations, the Company also engages in direct
communications with municipalities and private operators that deliver waste to
its transfer stations. This better positions the Company to gain additional
business in its markets in the event any municipality privatizes its solid waste
operations or rebids existing contracts, and it increases the Company's
opportunities to acquire private collection operations.
 
  Operating Enhancements
 
     The Company has developed company-wide operating standards, which are
tailored for each of its markets based on industry standards and local
conditions. Using these standards, the Company tracks collection and disposal
routing efficiency and equipment utilization. It also implements cost controls
and employee training and safety procedures, and establishes a sales and
marketing plan for each market. The Company has installed a wide area network,
implemented advanced management information systems and financial controls, and
consolidated accounting functions, customer service, productivity reporting and
dispatching systems. The Company believes that by establishing operating
standards, closely monitoring performance and streamlining certain
administrative functions, it can improve the profitability of existing
operations.
 
     To improve an acquired business' operational productivity, administrative
efficiency and profitability, the Company applies the same operating standards,
information systems and financial controls to acquired businesses as are
employed at the Company's existing operations. Moreover, if the Company is able
to internalize the waste stream of acquired operations, it can further increase
operating efficiencies and improve capital utilization. Where not restricted by
exclusive agreements, contracts, permits or certificates, the Company also
solicits new commercial, industrial and residential customers in areas within
and surrounding the markets served by acquired collection operations, as a means
of further improving operating efficiencies and increasing the volume of solid
waste collected by the acquired operations.
 
ACQUISITION PROGRAM
 
   
     The Company currently operates in Washington, California, Idaho, Wyoming
and South Dakota and believes that these and other markets in the Western U.S.
with similar characteristics offer significant opportunities for achieving its
objective. The Company focuses on markets that are generally characterized by:
(i) a geographically dispersed population, which the Company believes deters
competition from larger, established waste management companies; (ii) a
potential revenue base of at least $15 million; (iii) the opportunity for the
Company to acquire a significant market share; (iv) the availability of adequate
disposal capacity, either through acquisition by the Company or through
agreements with third parties; (v) a favorable regulatory environment; or (vi)
strong projected economic or population growth rates. The Company believes that
these market characteristics provide significant growth opportunities for a
well-capitalized market entrant and create economic and operational barriers to
entry by new competitors.
    
 
     The Company believes that its experienced management, decentralized
operating strategy, financial strength and size make it an attractive buyer to
certain solid waste collection and disposal acquisition candidates. The Company
has developed a set of financial, geographic and management
 
                                       36
<PAGE>   38
 
criteria to assist management in evaluating acquisition candidates. These
criteria evaluate a variety of factors, including, but not limited to: (i) the
candidate's historical and projected financial performance; (ii) the candidate's
internal rate of return, return on assets and return on revenue; (iii) the
experience and reputation of the candidate's management and customer service
providers, their relationships with local communities and their willingness to
continue as employees of the Company; (iv) the composition and size of the
candidate's customer base and whether the customer base is served under
franchise agreements, municipal contracts, governmental certificates or other
exclusive arrangements; (v) whether the geographic location of the candidate
will enhance or expand the Company's market area or ability to attract other
acquisition candidates; (vi) whether the acquisition will augment or increase
the Company's market share or help protect the Company's existing customer base;
(vii) any potential synergies that may be gained by combining the candidate with
the Company's existing operations; and (viii) the liabilities of the candidate.
 
     Before completing an acquisition, the Company performs extensive
environmental, operational, engineering, legal, human resources and financial
due diligence. All acquisitions are subject to initial evaluation and approval
by the Company's management before being recommended to the Executive Committee
of the Board of Directors. The Company seeks to integrate each acquired business
promptly and to minimize disruption to the ongoing operations of both the
Company and the acquired business, and generally attempts to retain the senior
management of acquired businesses. The Company believes its senior management
team has a proven track record in integrating acquisitions.
 
  Recent Acquisition Developments
 
     On January 30, 1998, the Company acquired from affiliates of the Company
the stock of Waste Connections of Idaho, Inc., a provider of solid waste
collection services to more than 10,000 customers in and around Idaho Falls and
Pocatello, Idaho through subscription agreements with residential customers and
seven municipal contracts. Waste Connections of Idaho, Inc. was formed in
September 1997 by affiliates of the Company for the purpose of acquiring certain
assets of Browning-Ferris Industries of Idaho, Inc. See "Certain Transactions."
 
     Effective February 1, 1998, the Company acquired Madera Disposal Systems,
Inc. ("Madera"), an integrated solid waste services company operating in north
central California, with 1997 revenues of approximately $7.8 million. In
connection with the Madera acquisition, the Company acquired one franchise
agreement and one municipal contract, pursuant to which it serves more than
9,000 commercial, industrial and residential customers, and agreements to
operate two transfer stations, one Subtitle D landfill (the "Fairmead Landfill")
and one recycling facility. The operating agreement for the Fairmead Landfill
has a remaining term of approximately 11 years. As of April 15, 1998, the
Fairmead Landfill is estimated to have a remaining life of approximately 26
years. Approximately 45% of the solid waste disposed of at the Fairmead Landfill
in 1997 was delivered by Madera.
 
     Effective March 1, 1998, the Company acquired certain solid waste
collection assets from Hunter Enterprises, Inc., a solid waste services company
located in eastern Idaho. These assets "tuck in" to the Company's Idaho
operations and serve approximately 2,800 residential and commercial customers.
 
     On April 8, 1998, the Company acquired certain solid waste collection
assets from A-1 Disposal, Inc. and Jesse's Disposal, both unrelated parties
operating in northeastern Wyoming, and together serving approximately 2,300
customers.
 
   
     On May 8, 1998, the Company acquired Sowers' Sanitation, Inc. and Sunshine
Sanitation Incorporated, providers of solid waste and recyclables collection
services to an aggregate of more than 7,000 customers in western South Dakota.
    
 
                                       37
<PAGE>   39
 
   
     On May 11, 1998, the Company acquired T&T Disposal, Inc., a provider of
solid waste and recyclables collection services to more than 500 customers in
eastern Wyoming.
    
 
  Letters of Intent to Acquire Additional Operations
 
   
     As of May 15, 1998, the Company had entered into nonbinding, preliminary
letters of intent relating to the possible acquisition of five collection and
transfer companies and one integrated collection and landfill company (five new
service markets), which the Company estimates represent aggregate annualized
revenues of more than $17.0 million. There can be no assurance that actual
revenues realized by the Company from the successful acquisition of these
potential acquisition candidates will not differ materially from the Company's
estimate or that any of these letters of intent will lead to completed
acquisitions on the terms currently contemplated.
    
 
SERVICES
 
  Commercial, Industrial and Residential Waste Services
 
   
     The Company serves more than 139,000 commercial, industrial and residential
customers. Of these, more than 49,000 are served under G certificates that grant
the Company rights, which are generally perpetual and exclusive, to provide
services within specified areas, approximately 6,600 are served under an
exclusive franchise agreement with a remaining term of 11 years, and
approximately 64,000 are served under exclusive municipal contracts with shorter
contract terms.
    
 
     The Company's commercial and industrial services that are not performed
under G certificates, franchise agreements or municipal contracts are provided
under one to five year service agreements. Fees under these agreements are
determined by such factors as collection frequency, level of service, route
density, the type, volume and weight of the waste collected, type of equipment
and containers furnished, the distance to the disposal or processing facility,
the cost of disposal or processing and prices charged in its markets for similar
service. Collection of larger volumes associated with commercial and industrial
waste streams generally helps improve the Company's operating efficiencies, and
consolidation of these volumes allows the Company to negotiate more favorable
disposal prices. The Company's commercial and industrial customers use portable
containers for storage, enabling the Company to service many customers with
fewer collection vehicles. Commercial and industrial collection vehicles
normally require one operator. The Company provides one to eight cubic yard
containers to commercial customers, 10 to 50 cubic yard containers to industrial
customers, and 30 to 95 gallon carts to residential customers. For an additional
fee, stationary compactors that compact waste prior to collection are installed
on the premises of a substantial number of large volume customers. No single
commercial or industrial contract is material to the Company's results of
operations.
 
     The Company's residential waste services that are not performed under G
certificates, franchise agreements or municipal contracts are provided under
contracts with homeowners' associations, apartment owners or mobile home park
operators, or on a subscription basis with individual households. Residential
contract fees are based primarily on route density, the frequency and level of
service, the distance to the disposal or processing facility, the cost of
disposal or processing and prices charged in that market for similar services.
Collection fees are paid either by the municipalities from tax revenues or
directly by the residents receiving the services.
 
  Transfer Station Services
 
     The Company has an active program to acquire, develop, own and operate
transfer stations in markets proximate to its operations. Currently, the Company
operates two transfer stations in California and one transfer station in
Washington which receive, compact, and transfer solid waste to larger vehicles
for transport to landfills. The Company believes that the transfer stations
benefit the Company by: (i) concentrating the waste stream from a wider area,
which increases the volume of
 
                                       38
<PAGE>   40
 
disposal at Company-operated landfills and gives the Company greater leverage in
negotiating for more favorable disposal rates at other landfills; (ii) improving
utilization of collections personnel and equipment; and (iii) building
relationships with municipalities and private operators that deliver waste,
which can lead to additional growth opportunities.
 
  Landfills
 
   
     The Company operates one Subtitle D landfill, the Fairmead Landfill, under
an operating agreement with Madera County with a remaining term of 11 years. In
fiscal 1997, approximately 45% of the solid waste disposed of at the Fairmead
Landfill was delivered by Madera. As of May 15, 1998, the Fairmead Landfill
consisted of 160 total acres, of which 20 acres were permitted for disposal. As
of that date, the Fairmead Landfill had approximately 600,000 tons of unused
permitted capacity remaining, with approximately 3.5 million additional tons of
capacity in various stages of permitting, and was estimated to have a remaining
life of 26 years. The Fairmead Landfill is currently permitted to accept up to
395 tons per day of municipal solid waste.
    
 
     The Company monitors the available permitted in-place disposal capacity of
the Fairmead Landfill on an ongoing basis and evaluates whether to seek to
expand this capacity. In making this evaluation, the Company considers various
factors, including the volume of waste projected to be disposed of at the
landfill, the size of the unpermitted acreage included in the landfill, the
likelihood that the Company will be successful in obtaining the necessary
approvals and permits required for the expansion and the costs that would be
involved in developing the additional capacity. The Company also regularly
considers whether it is advisable, in light of changing market conditions and/or
regulatory requirements, to seek to expand or change the permitted waste streams
or to seek other permit modifications.
 
     The Company is actively engaged in identifying solid waste landfill
acquisition candidates to achieve vertical integration in markets where the
economic and regulatory environment makes such acquisitions attractive. The
Company believes that in some markets, acquiring landfills would provide
opportunities to vertically integrate its collection, transfer and disposal
operations while improving operating margins. The Company evaluates landfill
candidates by determining, among other things, the amount of waste that could be
diverted to the landfill in question, whether access to the landfill is
economically feasible from the Company's existing market areas either directly
or through transfer stations, the expected life of the landfill, the potential
for expanding the landfill, and current disposal costs compared to the cost of
acquiring the landfill. Where the acquisition of a landfill is not attractive,
the Company pursues long term disposal contracts with facilities located in
proximity to its markets.
 
  Recycling and Other Services
 
     The Company offers municipal, commercial, industrial and residential
customers recycling services for a variety of recyclable materials, including
cardboard, office paper, plastic containers, glass bottles and ferrous and
aluminum metals. The Company operates one recycling processing facility and
sells other collected recyclable materials to third parties for processing
before resale. The profits from the Company's resale of recycled materials are
often shared between the Company and the other parties to its recycling
contracts. For example, certain of the Company's municipal recycling contracts
in Washington and Idaho, which were negotiated before the Company acquired those
businesses, specify certain benchmark resale prices for recycled commodities. To
the extent the prices the Company actually receives for the processed recycled
commodities collected under the contract exceed the prices specified in the
contract, the Company shares the excess with the municipality, after recovering
any previous shortfalls resulting from actual market prices falling below the
prices specified in the contract. In an effort to reduce its exposure to
commodity price risk with respect to recycled materials, the Company has adopted
a pricing strategy of charging collection and processing fees for recycling
volume collected from third parties. The Company believes that recycling will
continue to be an important component of local and state solid waste
                                       39
<PAGE>   41
 
management plans, due to the public's increasing environmental awareness and
expanding regulations that mandate or encourage recycling.
 
     The Company also provides other waste management services, most of which
are project-based, including transporting and disposing of non-hazardous
contaminated soils and similar materials, transporting special waste products,
including asbestos, and arranging for the transportation of construction and
demolition waste and disposal of soil and special waste products.
 
OPERATIONS
 
     The Company is managed on a decentralized basis, which places
decision-making authority close to the customer, enabling the Company to
identify customers' needs quickly and to address those needs in a cost-effective
manner. The Company believes that decentralization provides a low-overhead,
highly efficient operational structure that allows the Company to expand into
geographically contiguous markets and operate in relatively small communities
that larger competitors may not find attractive. The Company believes that this
structure gives the Company a strategic competitive advantage, given the
relatively rural nature of much of the Western U.S., and makes the Company an
attractive buyer to many potential acquisition candidates.
 
   
     The Company currently delivers its services from nine operating locations
serving six market areas, or districts. Each district has a district manager,
who has autonomous service and decision-making authority for that district and
is responsible for maintaining service quality, promoting safety in the
district's operations, implementing marketing programs, and overseeing
day-to-day operations, including contract administration. District managers also
assist in identifying acquisition candidates. Once the Company begins the
acquisition process, business development managers, under the supervision of
district and executive managers, obtain the permits and other governmental
approvals required for the Company to operate the acquired business, including
those related to zoning, environmental and land use.
    
 
     The Company's financial management, accounting, management information
systems, environmental compliance, risk management and certain personnel
functions are centralized and shared among locations to improve productivity,
lower operating costs and stimulate internal growth. The Company has installed a
Company-wide management information system that assists district personnel in
making decisions based on centralized, real-time financial, productivity,
maintenance and customer information. While district management operates with a
high degree of autonomy, the Company's senior officers monitor district
operations and require adherence to the Company's accounting, purchasing,
marketing and internal control policies, particularly with respect to financial
matters. The Company's executive officers review the performance of district
managers and operations on a regular basis.
 
G CERTIFICATES
 
   
     A substantial portion of the Company's collection business in Washington is
performed under G certificates awarded by the Washington Utilities and
Transportation Commission (the "WUTC"). G certificates apply only to
unincorporated areas of Washington and municipalities that have elected to have
their solid waste collection overseen by the WUTC. G certificates generally
grant the holder the perpetual right to provide specified solid waste collection
and transportation services in a specified territory. The WUTC has repeatedly
determined that, in enacting the statute authorizing G certificates, the
Washington Legislature intended to favor grants of exclusive, rather than
overlapping, service rights for conventional solid waste services. Accordingly,
most G certificates currently grant exclusive solid waste collection and
transportation rights for conventional solid waste services in their specified
territories.
    
 
     G certificates have generally been construed by the WUTC and the Washington
Legislature as conferring vested property rights that may be defeated,
diminished or cancelled only upon the occurrence of specified events of default,
the demonstrated lack of fitness of the certificate holder, or
                                       40
<PAGE>   42
 
   
municipalities' annexation of territory covered by a certificate. Thus, a
certificate holder is entitled to due process in challenging any action that
affects its rights. In addition, legislation passed in 1997 requires a
municipality that annexes territory covered by a G certificate either to grant
the certificate holder an exclusive franchise, generally with a minimum term of
seven years, to continue to provide services in the affected area, or to
negotiate with the certificate holder some other compensation for the collection
rights in the affected area. The statute expressly permits the certificate
holder to sue the annexing municipality for measurable damages that exceed the
value of a seven-year franchise agreement to provide services in the affected
area. Under one of the contracts with a municipality in Washington acquired by a
predecessor of the Company, the predecessor purported to waive its rights to
compensation or damages under the statute in return for the right to service any
current or prospectively annexed areas formerly covered by its G certificate.
    
 
   
     In addition to awarding G certificates, the WUTC is required by statute to
establish just, reasonable and compensatory rates to customers of regulated
solid waste collection companies. The WUTC is charged with balancing the needs
of service providers to earn fair and sufficient returns on their investments in
plant and equipment against the needs of commercial and residential customers to
receive adequate and reasonably priced services. Over the past decade, the WUTC
has employed a ratemaking methodology known as the "Lurito-Gallagher" method.
This method calculates rates based on the income statements and balance sheets
of each service provider, with the goal of establishing rates that reflect the
costs of providing service and that motivate service providers to invest in
equipment that improves operating efficiency in a cost-effective manner. The
Lurito-Gallagher rate-setting methodology was adjusted in the early 1990's to
better reflect the costs of providing recycling services, by accounting for
providers' increasing use of automated equipment and adjusting for the
cyclicality of the secondary recyclables markets. This has often resulted in
more frequent rate adjustments in response to material cost shifts.
    
 
SALES AND MARKETING
 
     In most of the Company's existing markets, waste collection, transfer and
disposal services are provided to municipalities and governmental authorities
under exclusive franchise agreements, municipal contracts and G certificates;
service providers do not contract directly with individual customers. In
addition, because the Company's growth to date has primarily been through
acquisitions, the Company has generally assumed existing franchise agreements,
municipal contracts and G certificates from the acquired companies, rather than
obtaining new contracts. For these reasons, the Company's sales and marketing
efforts to date have been narrowly focused. The Company expects to add sales and
marketing personnel as necessary to: (i) solicit new customers in markets where
it is not the exclusive provider of solid waste services; (ii) expand its
presence into areas adjacent to or contiguous with its existing markets; and
(iii) market additional services to existing customers.
 
   
     The Company has a diverse customer base. Its largest single contract, with
the City of Vancouver, accounted for approximately 18.1% of the Company's
revenues during the period from inception (September 9, 1997) through December
31, 1997, and 15.8% during the three months ended March 31, 1998. Under this
contract, the Company serves more than 34,000 residential and commercial
customers. There are approximately nine years remaining under that contract. No
other single contract or customer accounted for more than 7.1% of the Company's
revenues during the period from inception (September 9, 1997) through December
31, 1997 or 6.0% during the three months ended March 31, 1998. The weighted
average life of the Company's municipal contracts and franchise agreement, based
on revenues, is approximately seven years.
    
 
COMPETITION
 
     The solid waste services industry is highly competitive and fragmented and
requires substantial labor and capital resources. The industry presently
includes five large national waste companies: Allied Waste Industries, Inc.,
Browning-Ferris Industries, Inc., Republic Industries, Inc., USA Waste Services,
Inc. and Waste Management, Inc. (which has announced an impending merger with
USA
                                       41
<PAGE>   43
 
Waste Services, Inc.) Several other public companies have annual revenues in
excess of $100 million, including American Disposal Services, Inc., Casella
Waste Systems, Inc., Eastern Environmental Services, Inc., Superior Services,
Inc. and Waste Industries, Inc. Certain of the markets in which the Company
competes or will likely compete are served by one or more large, national solid
waste companies, as well as by numerous regional and local solid waste companies
of varying sizes and resources, some of which have accumulated substantial
goodwill in their markets. The Company also competes with operators of
alternative disposal facilities, including incinerators, and with counties,
municipalities, and solid waste districts that maintain their own waste
collection and disposal operations. Public sector operations may have financial
advantages over the Company, because of their access to user fees and similar
charges, tax revenues and tax-exempt financing.
 
     The Company competes for collection, transfer and disposal volume based
primarily on the price and quality of its services. From time to time,
competitors may reduce the price of their services in an effort to expand their
market shares or service areas or to win competitively bid municipal contracts.
These practices may cause the Company to reduce the price of its services or, if
it elects not to do so, to lose business. The Company provides a substantial
portion of its residential, commercial and industrial collection services under
exclusive franchise and municipal contracts and certificates, some of which are
subject to periodic competitive bidding. The balance of the Company's services
are provided under subscription agreements with individual households and one to
five year service contracts with commercial and industrial customers.
 
     Intense competition exists not only for collection, transfer and disposal
volume, but also for acquisition candidates. The Company generally competes for
acquisition candidates with publicly owned regional and large national waste
management companies.
 
REGULATION
 
  Introduction
 
   
     The Company is subject to extensive and evolving federal, state and local
environmental laws and regulations, the enforcement of which has become
increasingly stringent in recent years. The environmental regulations affecting
the Company are administered by the EPA and other federal, state and local
environmental, zoning, health and safety agencies. A substantial portion of the
Company's collection business in Washington is performed under G certificates
awarded by the Washington Utilities and Transportation Commission, which
generally grant the Company perpetual and exclusive collection rights in certain
areas. The Company is currently in substantial compliance with applicable
federal, state and local environmental laws, permits, orders and regulations,
and it does not currently anticipate any material environmental costs necessary
to bring its operations into compliance (although there can be no assurance in
this regard). The Company anticipates that regulation, legislation and
regulatory enforcement actions related to the solid waste services industry will
continue to increase. The Company attempts to anticipate future regulatory
requirements and to plan in advance as necessary to comply with them.
    
 
     To transport solid waste, the Company must possess and comply with one or
more permits from state or local agencies. These permits also must be
periodically renewed and may be modified or revoked by the issuing agency.
 
     The principal federal, state and local statutes and regulations that apply
to the Company's operations are described below.
 
  The Resource Conservation and Recovery Act of 1976 ("RCRA")
 
     RCRA regulates the generation, treatment, storage, handling, transportation
and disposal of solid waste and requires states to develop programs to ensure
the safe disposal of solid waste. RCRA divides solid waste into two groups,
hazardous and nonhazardous. Wastes are generally classified as hazardous if they
either (i) are specifically included on a list of hazardous wastes, or (ii)
exhibit
 
                                       42
<PAGE>   44
 
certain characteristics defined as hazardous. Household wastes are specifically
designated as nonhazardous. Wastes classified as hazardous under RCRA are
subject to much stricter regulation than wastes classified as nonhazardous, and
businesses that deal with hazardous waste are subject to regulatory obligations
in addition to those imposed on handlers of nonhazardous waste.
 
     The EPA regulations issued under Subtitle C of RCRA impose a comprehensive
"cradle to grave" system for tracking the generation, transportation, treatment,
storage and disposal of hazardous wastes. The Subtitle C Regulations impose
obligations on generators, transporters and disposers of hazardous wastes, and
require permits that are costly to obtain and maintain for sites where such
material is treated, stored or disposed. Subtitle C requirements include
detailed operating, inspection, training and emergency preparedness and response
standards, as well as requirements for manifesting, record keeping and
reporting, corrective action, facility closure, post-closure and financial
responsibility. Most states have promulgated regulations modelled on some or all
of the Subtitle C provisions issued by the EPA. Some state regulations impose
different, additional and more stringent obligations, and may regulate certain
materials as hazardous wastes that are not so regulated under the federal
Subtitle C Regulations. From the date of inception through March 31, 1998, the
Company did not, to its knowledge, transport hazardous wastes in volumes that
would subject the Company to hazardous waste regulations under RCRA.
 
     In October 1991, the EPA adopted the Subtitle D Regulations governing solid
waste landfills. The Subtitle D Regulations, which generally became effective in
October 1993, include location restrictions, facility design standards,
operating criteria, closure and post-closure requirements, financial assurance
requirements, groundwater monitoring requirements, groundwater remediation
standards and corrective action requirements. In addition, the Subtitle D
Regulations require that new landfill sites meet more stringent liner design
criteria (typically, composite soil and synthetic liners or two or more
synthetic liners) intended to keep leachate out of groundwater and have
extensive collection systems to carry away leachate for treatment prior to
disposal. Groundwater monitoring wells must also be installed at virtually all
landfills to monitor groundwater quality and, indirectly, the effectiveness of
the leachate collection system. The Subtitle D Regulations also require, where
certain regulatory thresholds are exceeded, that facility owners or operators
control emissions of methane gas generated at landfills in a manner intended to
protect human health and the environment. Each state is required to revise its
landfill regulations to meet these requirements or such requirements will be
automatically imposed by the EPA on landfill owners and operators in that state.
Each state is also required to adopt and implement a permit program or other
appropriate system to ensure that landfills in the state comply with the
Subtitle D Regulations. Various states in which the Company operates or in which
it may operate in the future have adopted regulations or programs as stringent
as, or more stringent than, the Subtitle D Regulations.
 
  The Federal Water Pollution Control Act of 1972, as amended
  (the "Clean Water Act")
 
     The Clean Water Act regulates the discharge of pollutants from a variety of
sources, including solid waste disposal sites and transfer stations, into waters
of the United States. If run-off from the Company's transfer stations or run-off
or collected leachate from the Company's owned or operated landfills is
discharged into streams, rivers or other surface waters, the Clean Water Act
would require the Company to apply for and obtain a discharge permit, conduct
sampling and monitoring and, under certain circumstances, reduce the quantity of
pollutants in such discharge. Also, virtually all landfills are required to
comply with the EPA's storm water regulations issued in November 1990, which are
designed to prevent contaminated landfill storm water runoff from flowing into
surface waters. The Company believes that its facilities comply in all material
respects with the Clean Water Act requirements. Various states in which the
Company operates or in which it may operate in the future have been delegated
authority to implement the Clean Water Act permitting requirements, and some of
these states have adopted regulations that are more stringent than the federal
 
                                       43
<PAGE>   45
 
requirements. For example, states often require permits for discharges to ground
water as well as surface water.
 
  The Comprehensive Environmental Response, Compensation,
  and Liability Act of 1980 ("CERCLA")
 
     CERCLA established a regulatory and remedial program intended to provide
for the investigation and cleanup of facilities where or from which a release of
any hazardous substance into the environment has occurred or is threatened.
CERCLA's primary mechanism for remedying such problems is to impose strict joint
and several liability for cleanup of facilities on current owners and operators
of the site, former owners and operators of the site at the time of the disposal
of the hazardous substances, any person who arranges for the transportation,
disposal or treatment of the hazardous substances, and the transporters who
select the disposal and treatment facilities. CERCLA also imposes liability for
the cost of evaluating and remedying any damage to natural resources. The costs
of CERCLA investigation and cleanup can be very substantial. Liability under
CERCLA does not depend on the existence or disposal of "hazardous waste" as
defined by RCRA; it can also be based on the existence of even very small
amounts of the more than 700 "hazardous substances" listed by the EPA, many of
which can be found in household waste. In addition, the definition of "hazardous
substances" in CERCLA incorporates substances designated as hazardous or toxic
under the federal Clean Water Act, Clear Air Act and Toxic Substances Control
Act. If the Company were found to be a responsible party for a CERCLA cleanup,
the enforcing agency could hold the Company, or any other generator, transporter
or the owner or operator of the contaminated facility, responsible for all
investigative and remedial costs, even if others were also liable. CERCLA also
authorizes the imposition of a lien in favor of the United States on all real
property subject to, or affected by, a remedial action for all costs for which a
party is liable. CERCLA gives a responsible party the right to bring a
contribution action against other responsible parties for their allocable shares
of investigative and remedial costs. The Company's ability to obtain
reimbursement from others for their allocable shares of such costs would be
limited by the Company's ability to find other responsible parties and prove the
extent of their responsibility and by the financial resources of such other
parties.
 
  The Clean Air Act
 
     The Clean Air Act generally, through state implementation of federal
requirements, regulates emissions of air pollutants from certain landfills based
on the date of the landfill construction and volume per year of emissions of
regulated pollutants. Larger landfills and landfills located in areas that do
not comply with certain requirements of the Clean Air Act may be subject to even
more extensive air pollution controls and emission limitations. In addition, the
EPA has issued standards regulating the disposal of asbestos-containing
materials. Air permits to construct may be required for gas collection and
flaring systems, and operating permits may be required, depending on the
estimated volume of emissions.
 
     All of the federal statutes described above contain provisions authorizing,
under certain circumstances, the institution of lawsuits by private citizens to
enforce the provisions of the statutes. In addition to a penalty award to the
United States, some of those statutes authorize an award of attorneys' fees to
parties successfully advancing such an action.
 
                                       44
<PAGE>   46
 
  The Occupational Safety and Health Act of 1970 (the "OSH Act")
 
     The OSH Act is administered by the Occupational Safety and Health
Administration ("OSHA"), and in many states by state agencies whose programs
have been approved by OSHA. The OSH Act establishes employer responsibilities
for worker health and safety, including the obligation to maintain a workplace
free of recognized hazards likely to cause death or serious injury, to comply
with adopted worker protection standards, to maintain certain records, to
provide workers with required disclosures and to implement certain health and
safety training programs. Various OSHA standards may apply to the Company's
operations, including standards concerning notices of hazards, safety in
excavation and demolition work, the handling of asbestos and asbestos-containing
materials, and worker training and emergency response programs.
 
  Flow Control/Interstate Waste Restrictions
 
     Certain permits and approvals, as well as certain state and local
regulations, may limit a landfill to accepting waste that originates from
specified geographic areas, restrict the importation of out-of-state waste or
otherwise discriminate against out-of-state waste. These restrictions, generally
known as flow control restrictions, are controversial, and some courts have held
that some flow control schemes violate constitutional limits on state or local
regulation of interstate commerce. From time to time, federal legislation is
proposed that would allow some local flow control restrictions. Although no such
federal legislation has been enacted to date, 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 or direct that
wastes be handled at specified facilities. Such state actions could adversely
affect the Company's landfills. 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
business, financial condition and results of operations could be adversely
affected.
 
     Even in the absence of federal legislation, certain state and local
jurisdictions may seek to enforce flow control restrictions through local
legislation or contractually and, in certain cases, the Company may elect not to
challenge such restrictions based on various considerations. 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 the Company can charge 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
business, financial condition and results of operations could be adversely
affected.
 
  State and Local Regulation
 
     Each state in which the Company now operates or may operate in the future
has laws and regulations governing the generation, storage, treatment, handling,
transportation and disposal of solid waste, occupational safety and health,
water and air pollution and, in most cases, the siting, design, operation,
maintenance, closure and post-closure maintenance of landfills and transfer
stations. In addition, many states have adopted statutes comparable to, and in
some cases more stringent than, CERCLA. These statutes impose requirements for
investigation and cleanup of contaminated sites and liability for costs and
damages associated with such sites, and some provide for the imposition of liens
on property owned by responsible parties. Furthermore, many municipalities also
have ordinances, local laws and regulations affecting Company operations. These
include zoning and health measures that limit solid waste management activities
to specified sites or activities, flow control provisions that direct the
delivery of solid wastes to specific facilities, laws that grant the right to
establish franchises for collection services and then put such franchises out
for bid, and bans or other restrictions on the movement of solid wastes into a
municipality.
 
                                       45
<PAGE>   47
 
     Permits or other land use approvals with respect to a landfill, as well as
state or local laws and regulations, may specify the quantity of waste that may
be accepted at the landfill during a given time period, and/or specify the types
of waste that may be accepted at the landfill. Once an operating permit for a
landfill is obtained, it must generally be renewed periodically.
 
     There has been an increasing trend at the state and local level to mandate
and encourage waste reduction at the source and waste recycling, and to prohibit
or restrict the disposal of certain types of solid wastes, such as yard wastes,
leaves and tires, in landfills. The enactment of regulations reducing the volume
and types of wastes available for transport to and disposal in landfills could
affect the Company's ability to operate its facilities at their full capacity.
 
     Some state and local authorities enforce certain federal laws in addition
to state and local laws and regulations. For example, in some states, RCRA, the
OSH Act, parts of the Clean Air Act and parts of the Clean Water Act are
enforced by local or state authorities instead of by the EPA, and in some states
those laws are enforced jointly by state or local and federal authorities.
 
  Public Utility Regulation
 
     The rates that landfill operators may charge are regulated in many states
by public authorities. The rates that the Company may charge at its Fairmead
Landfill for the disposal of municipal solid waste are regulated by the Madera
County Board of Supervisors. The adoption of rate regulation or the reduction of
current rates in states in which the Company owns or operates landfills could
have an adverse effect on the Company's business, financial condition and
results of operations.
 
     Solid waste collection services in all unincorporated areas of Washington
and in electing municipalities in Washington are provided under G certificates
awarded by the Washington Utilities and Transportation Commission. The WUTC also
sets rates for regulated solid waste collection services in Washington.
 
RISK MANAGEMENT, INSURANCE AND PERFORMANCE BONDS
 
     The Company maintains an environmental and other risk management programs
appropriate for its business. The Company's environmental risk management
program includes evaluating existing facilities and potential acquisitions for
environmental law compliance. The Company does not presently expect
environmental compliance costs to increase above current levels, but the Company
cannot predict whether future acquisitions will result in an increase in such
costs. The Company also maintains a worker safety program that encourages safe
practices in the workplace. Operating practices at all Company operations
emphasize minimizing the possibility of environmental contamination and
litigation. The Company's facilities comply in all material respects with
applicable federal and state regulations.
 
     The Company carries a broad range of insurance, which the Company's
management considers adequate to protect the Company's assets and operations.
The coverage includes general liability, comprehensive property damage,
workmen's compensation and other coverage customary in the industry. These
policies generally exclude coverage for damages associated with environmental
conditions. Because of the limited availability and high cost of environmental
impairment liability insurance, and in light of the Company's limited landfill
operations, the Company has not obtained such coverage. If the Company were to
incur liability for environmental cleanups, corrective action or damage, its
financial condition could be materially and adversely affected. The Company will
continue to investigate the possibility of obtaining environmental impairment
liability insurance, particularly if it acquires landfills or operates landfills
other than the Fairmead Landfill. The Company believes that most other landfill
operators do not carry such insurance.
 
     Municipal solid waste collection contracts may require performance bonds or
other means of financial assurance to secure contractual performance. Certain
environmental regulations also require demonstrated financial assurance to meet
closure and post-closure requirements for
 
                                       46
<PAGE>   48
 
   
landfills. The Company has not experienced difficulty in obtaining performance
bonds or letters of credit for its current operations. At May 15, 1998, the
Company had provided customers and various regulatory authorities with bonds and
letters of credit in the aggregate amount of approximately $800,000 to secure
its obligations. The Company's credit facility provides for the issuance of
letters of credit in an amount up to $5 million, but any letters of credit
issued reduce the availability of borrowings for acquisitions and other general
corporate purposes. If the Company were unable to obtain surety bonds or letters
of credit in sufficient amounts or at acceptable rates, it could be precluded
from entering into additional municipal solid waste collection contracts or
obtaining or retaining landfill operating permits.
    
 
PROPERTY AND EQUIPMENT
 
   
     The Company leases the real estate, buildings and other physical properties
for its solid waste operations. These leases include a lease of approximately
5,500 square feet of office space in Roseville, California for the Company's
principal executive offices, which lease expires in November 2002. The Company
also leases real property in Issaquah, Washington under a lease expiring in 2008
and in Maltby, Washington, Idaho Falls and Pocatello, Idaho, under leases
expiring at the end of 1999. The Company subleases real property in Vancouver,
Washington under a lease expiring in 2001, with an option to extend the term for
five years. The Company leases real property in Deadwood, South Dakota and
Converse County, Wyoming under leases expiring in 2003 and late 1998,
respectively. Under its agreement with the County of Madera to operate Fairmead
Landfill, the Company is permitted to maintain an equipment yard and office on
the landfill premises without charge. In connection with two recent acquisitions
in Wyoming, the Company acquired ownership of real estate formerly used by one
of the collection operations and assumed a lease that terminates in August 1998.
The Company expects to renew this lease and consolidate its operations in
Gillette, Wyoming, at the leased facility and to dispose of the real estate that
it acquired in connection with those acquisitions. In connection with recent
acquisitions in Wyoming and South Dakota, the Company also acquired real estate
in Wright, Wyoming and Butte County, South Dakota.
    
 
   
     At May 15, 1998, the Company owned or leased approximately 170 pieces of
equipment, including waste collection vehicles and related support vehicles, as
well as bulldozers, compactors, earth movers and related heavy equipment used in
landfill operations, and had more than 62,000 carts and containers in use, with
such carts ranging in size from 30 to 95 gallons and such containers ranging
from one to 50 cubic yards. The Company has a regular maintenance program for
its vehicles, equipment and operating properties. However, the Company expects
to make substantial investments in additional equipment and property for
expansion and replacement of assets and in connection with future acquisitions.
    
 
EMPLOYEES
 
   
     At May 15, 1998, the Company employed approximately 266 full-time
employees, including approximately 30 persons classified as professionals or
managers, approximately 209 employees involved in collection, transfer, disposal
and recycling operations, and approximately 27 sales, clerical, data processing
or other administrative employees.
    
 
     Approximately 55 drivers and mechanics at the Company's Vancouver,
Washington operation are represented by the Teamsters Union, with which
Browning-Ferris Industries of Washington, Inc., the Company's predecessor in
Vancouver, entered a four-year collective bargaining agreement in January 1997.
In addition, in July 1997, the employees at the Company's facility in Issaquah,
Washington, adopted a measure to select a union to represent them in labor
negotiations with management. The union and management are currently operating
under a one-year negotiating agreement, and, if those negotiations are
unsuccessful, the earliest date on which the union would be permitted to take
additional action is July 27, 1998. Such additional action includes calling a
strike or, if the Company agrees, continuing to negotiate or commencing
arbitration of the
 
                                       47

outstanding issues. The Company is not aware of any other organizational efforts
among its employees and believes that its relations with its employees are good.
 
LEGAL PROCEEDINGS
 
     In the normal course of its business and as a result of the extensive
governmental regulation of the solid waste industry, the Company may
periodically become subject to various judicial and administrative proceedings
involving federal, state or local agencies. In these proceedings, an agency may
seek to impose fines on the Company or to revoke or deny renewal of an operating
permit held by the Company. From time to time, the Company may also be subject
to actions brought by citizens' groups or adjacent landowners or residents in
connection with the permitting and licensing of landfills and transfer stations,
or alleging environmental damage or violations of the permits and licenses
pursuant to which the Company operates.
 
     In addition, the Company may become party to various claims and suits
pending for alleged damages to persons and property, alleged violations of
certain laws and alleged liabilities arising out of matters occurring during the
normal operation of a waste management business. However, there is no current
proceeding or litigation involving the Company that the Company believes will
have a material adverse impact on the Company's business, financial condition,
results of operations or cash flows.

(1) The options and warrant were granted at or above fair market value as
    determined by the Board of Directors on the date of grant.
   
(2) Amounts reported in these columns represent amounts that may be realized on
    exercise of options and warrant immediately prior to the expiration of their
    term assuming the specified assumed rates of stock price appreciation (5%
    and 10%) on the Company's Common Stock over the term of the options and
    warrant, assuming an initial public offering price of $11.00 per share. The
    potential realizable values set forth above do not take into account
    applicable tax and expense payments that may be associated with such
    exercises. Actual realizable value, if any, will depend on the future price
    of the Common Stock on the actual date of exercise, which may be earlier
    than the stated expiration date. The 5% and 10% assumed annualized rates of
    stock price appreciation over the exercise period of the options and
    warrants used in the table above are mandated by the rules of the Securities
    and Exchange Commission (the "Commission") and do not represent the
    Company's estimate or projection of the future price of the Common Stock on
    any date. There is no representation, either express or implied, that the
    stock price appreciation rates for the Common Stock assumed for purposes of
    this table will actually be achieved.

(1) There was no public trading market for the Company's Common Stock at
    December 31, 1997. Accordingly, as permitted by the rules of the Commission,
    these values have been calculated based on the fair market value of the
    Company's Common Stock as of December 31, 1997, of $2.02 per share, as
    determined by the Board of Directors based on an independent valuation, less
    the aggregate exercise price.
 
EMPLOYMENT AGREEMENTS
 
     The Company has entered into employment agreements with Steven F. Bouck,
Eugene V. Dupreau, Charles B. Youngclaus, Darrell W. Chambliss, Michael R. Foos
and Eric J. Moser. Each agreement has a three-year term.
 
     The Company entered into an employment agreement with Ronald J.
Mittelstaedt, the President and the Chief Executive Officer, on October 1, 1997.
The initial annual base salary is $170,000. If this offering is consummated by
October 1, 1998, Mr. Mittelstaedt's base salary will be adjusted to at least
$250,000. The agreement provides for a minimum bonus of $125,000 for the
15-month period ending December 31, 1998, if the Company achieves certain
acquisition and financial targets.
 
     The agreement provides for an initial five-year term, at the end of which
the agreement automatically renews for additional successive one-year terms
unless terminated earlier upon written notice of either Mr. Mittelstaedt or the
Company or extended further by the Board. The Company or Mr. Mittelstaedt may at
any time terminate the agreement, with or without cause, provided that if the
Company terminates the agreement without cause (as defined in the agreement) or
if Mr. Mittelstaedt terminates the agreement for good reason (as defined in the
agreement), the Company is required to make certain severance payments, and all
of Mr. Mittelstaedt's unvested options, warrants and rights relating to capital
stock of the Company will immediately vest. The agreement also provides that a
change of control of the Company (as defined in the agreement) will be deemed a
termination of Mr. Mittelstaedt without cause, unless Mr. Mittelstaedt waives
that provision.
 
     Pursuant to the employment agreement, the Company sold Mr. Mittelstaedt
617,500 shares of the Company's Common Stock for $0.01 per share and 357,143
shares of the Company's Series A Preferred Stock for $1,000,000. Mr.
Mittelstaedt may recommend nominees for election to the Company's Board of
Directors. If the Board consists of five or fewer members, Mr. Mittelstaedt may
recommend two nominees, and if it consists of more than five members, he may
recommend three nominees.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The full Board of Directors served as the compensation committee of the
Board during 1997. At the time the employment agreement with Mr. Mittelstaedt
was approved by the Board of Directors,
 
                                       53
<PAGE>   55
 
Mr. Mittelstaedt was one of three members of the Board of Directors. No
executive officer of the Company served as a director or member of the
compensation committee of another entity, one of whose executive officers served
as a director or member of the Compensation Committee of the Company.
 
1997 STOCK OPTION PLAN
 
   
     The 1997 Stock Option Plan (the "Stock Option Plan") was adopted by the
Board of Directors effective as of October 1, 1997, and was approved by the
stockholders on March 12, 1998. The Stock Option Plan is intended to provide
employees, consultants and directors with additional incentives by increasing
their proprietary interests in the Company. Under the Stock Option Plan, the
Company may grant options with respect to a maximum of 1,200,000 shares of
Common Stock. As of May 15, 1998, the Company had granted options to purchase
880,600 shares of Common Stock at a weighted average exercise price of $5.44 per
share.
    
 
     The Stock Option Plan is currently administered by the Board of Directors.
Upon consummation of the offering, the Compensation Committee will administer
the Stock Option Plan. The administrator of the Stock Option Plan has the
authority to determine the employees, consultants and directors to whom options
are granted (the "Optionees"), the type, size and term of the options, the grant
date, the expiration date, the vesting schedule and other terms and conditions
of the options.
 
     The Stock Option Plan provides for the grant of incentive stock options
("ISOs") as defined in section 422 of the Internal Revenue Code, as amended, and
nonqualified stock options. Only employees of the Company may receive ISOs. The
aggregate fair market value, as of the grant date, of the Common Stock subject
to ISOs that become exercisable by any employee during any calendar year may not
exceed $100,000. Options generally become exercisable in installments pursuant
to a vesting schedule set forth in the option agreement. No option shall be
granted after September 30, 2007. No option will remain exercisable later than
10 years after the grant date (or five years in the case of ISOs granted to
Optionees owning more than 10% of the total combined voting power of all classes
of the Company's outstanding capital stock (a "Ten Percent Stockholder")). The
exercise price of ISOs granted under the Stock Option Plan may be no less than
the fair market value of a share of Common Stock on the grant date (or 110% of
such fair market value, in the case of ISOs granted to Ten Percent
Stockholders).
 
     If an Optionee with outstanding options retires or becomes disabled and
does not die within the three months following retirement or disability, the
Optionee may exercise his or her options, but only within the period ending,
subject to the discretion of the administrator of the Stock Option Plan, on the
earlier of: (i) six months after retirement or disability; or (ii) the
expiration of the option set forth in the option agreement. If the Optionee does
not exercise his or her options within that time period, the options will
terminate, and the shares of Common Stock subject to the options will become
available for issuance under the Stock Option Plan. If the Optionee ceases to be
an employee, consultant or director of the Company other than because of
retirement, death or disability, his or her options terminate on the date such
relationship terminates, subject to the discretion of the administrator of the
Stock Option Plan, and the shares of Common Stock subject to the options will
become available for issuance under the Stock Option Plan. Each option agreement
may include the right of the Company to repurchase any and all shares acquired
by an Optionee under the Stock Option Plan upon termination of the Optionee,
whether voluntary or involuntary or with or without cause.

for such shares. Messrs. Mittelstaedt, Bishop and Cutler formed Waste
Connections Idaho in September 1997 for the purpose of acquiring certain assets
from Browning-Ferris Industries of Idaho, Inc.

     Eugene V. Dupreau was President and a 16.7% shareholder of Madera Disposal

LLC, an Oregon limited liability company doing business as Fibres International
("Fibres"). J. Bradford Bishop and James N. Cutler, Jr. own 60% of the
membership interests in Fibres, were directors of the Company when some of these
transactions occurred and may be deemed promoters of the Company. In markets
where Fibres has processing facilities (which include three of the Company's
four current markets), the Company delivers to Fibres' processing facilities all
of the Company's collected recyclable materials for which Fibres pays the market
rate (adjusted to reflect the Company's costs of transporting the materials to
Fibres or another processor) otherwise obtainable by the Company for such
materials. The gross revenues received by the Company from Fibres from the
Company's inception through December 31, 1997, were approximately $222,701. The
net amount retained by the Company, after deducting the fees the Company paid to
Fibres for the right to collect the recyclables, was approximately $10,860 for
such period.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
     The authorized capital stock of the Company consists of 50,000,000 shares
of Common Stock, par value $0.01 per share, and 10,000,000 shares of Preferred
Stock, par value $0.01 per share (the "Preferred Stock"). As of the date of this
Prospectus, there are 3,432,726 shares of Common Stock outstanding and 2,499,998
shares of Series A Preferred Stock outstanding. The Series A Preferred shares
will automatically convert to 2,499,998 shares of Common Stock upon the
consummation of this offering. After giving effect to this offering, there will
be 7,932,724 shares of Common Stock outstanding (8,232,724 if the Underwriters'
over-allotment option is exercised in full).
    
 
     The following description of the Company's capital stock is a summary of
the material terms of such stock. The following does not purport to be complete
and is subject in all respects to applicable Delaware law and to the provisions
of the Company's Amended and Restated Certificate of Incorporation and Amended
and Restated By-laws.
 
COMMON STOCK
 
     The holders of shares of Common Stock are entitled to one vote per share
held on all matters submitted to a vote at a meeting of stockholders. Cumulative
voting for the election of directors is not permitted. Subject to such
preferences to which holders of shares of Preferred Stock, if any, may be
entitled, the holders of outstanding shares of Common Stock are entitled to
receive ratably such dividends, if any, as may be declared from time to time by
the Board of Directors out of funds legally available therefor. In the event of
a liquidation, dissolution or winding up of the Company, the holders of
outstanding shares of Common Stock are entitled to share ratably in all assets
of the Company which are legally available for distribution to stockholders,
subject to the prior rights on liquidation of creditors and to preferences, if
any, to which holders of shares of Preferred Stock, if any, may be entitled. In
connection with the acquisition of Madera, the Company issued 1,000,000 shares
of Common Stock, which was redeemable under certain circumstances. Upon the
consummation of this offering, those shares will no longer be redeemable. The
holders of outstanding shares of Common Stock do not have any preemptive,
subscription, redemption, conversion or sinking fund rights. The outstanding
shares of Common Stock are fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Company is authorized by its Amended and Restated Certificate of
Incorporation to issue a maximum of 10,000,000 shares of Preferred Stock, in one
or more series and containing such rights, privileges and limitations, including
dividend rights, voting rights, conversion privileges, redemption rights,
liquidation rights and/or sinking fund rights, as may from time to time be
determined by the Board of Directors of the Company. The Company has issued
2,499,998 shares of Series A Preferred Stock, which on the closing of this
offering will convert automatically to 2,499,998 shares of Common Stock. The
Series A Preferred Stock provides for cumulative dividends, which if not paid in
cash prior to the Preferred Stock's conversion into Common Stock are to be paid
in additional shares of Common Stock. The Company intends to pay any such
accumulated dividends in cash prior to conversion. Additional Preferred Stock
may be issued in the future in connection with acquisitions, financings or such
other matters as the Board of Directors deems to be appropriate. The effect of
having such Preferred Stock authorized is that the Company's Board of Directors
alone, within the bounds and subject to the federal securities laws and the
Delaware General Corporation Law (the "Delaware Law"), may be able to authorize
the issuance of Preferred Stock, which may adversely affect the voting and other
rights of holders of Common Stock. The issuance of Preferred Stock may also have
the effect of delaying, deferring or preventing a change in control of the
Company.

CERTAIN STATUTORY, CHARTER AND BY-LAW PROVISIONS
 
     The following brief description of certain provisions of the Delaware Law
and the Company's Amended and Restated Certificate of Incorporation (the
"Restated Certificate") and Amended and Restated By-laws (the "Restated
By-laws") does not purport to be complete and is subject in all respects to the
provisions of the Delaware Law, the Restated Certificate and the Restated
By-laws, copies of which have been filed as exhibits to the Registration
Statement of which this Prospectus forms a part.
 
     Classified Board of Directors. The Restated Certificate provides that the
Board shall be divided into three classes and that the number of directors in
each class shall be as nearly equal as is possible based on the number of
directors constituting the entire Board. The Restated Certificate effectively
provides that the term of office of the first class will expire at the annual
meeting of stockholders following December 31, 1998, the term of office of the
second class will expire at the annual meeting of stockholders following
December 31, 1999, and the term of office of the third class will expire at the
annual meeting of stockholders following December 31, 2000. At each annual
meeting of stockholders, successors to directors of the class whose term expires
at such meeting will be elected to serve for three-year terms and until their
successors are elected and qualified.
 
     The classification of directors has the effect of making it more difficult
for stockholders to change the composition of the Board. At least two annual
meetings of stockholders, instead of one, will generally be required to effect a
change in a majority of the Board. Such a delay may help ensure that the
Company's directors, if confronted by a third party attempting to force a proxy
contest, a tender or exchange offer or other extraordinary corporate
transaction, would have sufficient time to review the proposal as well as any
available alternatives to the proposal and to act in what they believe to be the
best interests of the stockholders. However, such classification provisions
could also have the effect of discouraging a third party from initiating a proxy
contest, making a tender offer or otherwise attempting to obtain control of the
Company, even though such an attempt might be beneficial to the Company and its
stockholders. The classification of the Board could thus increase the likelihood
that incumbent directors will retain their positions.
 
     Number of Directors; Removal; Filling Vacancies. The Restated Certificate
provides that, subject to any rights of holders of Preferred Stock to elect
additional directors under specified circumstances, the number of directors
comprising the entire Board will be fixed from time to time by action of not
less than a majority of the directors then in office. In no event shall such
number be less than three or more than nine, unless approved by action of not
less than two-thirds of the directors then in office. In addition, the Restated
Certificate provides that, subject to any rights of holders of Preferred Stock,
newly created directorships resulting from an increase in the authorized number
of directors, vacancies on the Board resulting from death, resignation,
retirement, disqualification or removal of directors or any other cause may be
filled only by the Board (and not by the stockholders unless there are no
directors in office), provided that a quorum is then in office and present, or
by a majority of the directors then in office, if less than a quorum is then in
office, or by the sole remaining director. Accordingly, the Board could prevent
any stockholder from enlarging the Board and filling the new directorships with
such stockholder's own nominees.
 
     Under the Delaware Law, unless otherwise provided in the certificate of
incorporation, directors serving on a classified board may only be removed by
the stockholders for cause. The Restated Certificate provides that following the
offering, directors may be removed only for cause and only on the affirmative
vote of holders of at least 66 2/3% of the voting power of all the then
outstanding shares of stock entitled to vote generally in the election of
directors ("Voting Stock"), voting together as a single class.
 
     The provisions of the Restated Certificate governing the number of
directors, their removal and the filling of vacancies may have the effect of
discouraging a third party from initiating a proxy contest, making a tender
offer or otherwise attempting to gain control of the Company, or of attempting
to change the composition or policies of the Board, even though such attempts
might be
                                       60
<PAGE>   62
 
beneficial to the Company or its stockholders. These provisions of the Restated
Certificate could thus increase the likelihood that incumbent directors retain
their positions.
 
     Limitation on Special Meetings; No Stockholder Action by Written
Consent. The Restated Certificate and the Restated By-laws provide that (subject
to the rights, if any, of holders of any class or series of Preferred Stock then
outstanding): (i) only a majority of the Board of Directors or the President or
Chairman of the Board will be able to call a special meeting of stockholders;
(ii) the business permitted to be conducted at a special meeting of stockholders
shall be limited to matters stated in the notice of meeting or properly brought
before the meeting by or at the direction of the Board of Directors; and (iii)
following the offering, stockholder action may be taken only at a duly called
and convened annual or special meeting of stockholders and may not be taken by
written consent. These provisions, taken together, prevent stockholders from
forcing consideration by the stockholders of stockholder proposals over the
opposition of the Board, except at an annual meeting.
 
     Advance Notice Provisions for Stockholder Nominations and Stockholder
Proposals. The Restated By-laws establish an advance notice procedure for
stockholders to make nominations of candidates for election as director, or to
bring other business before an annual meeting of stockholders of the Company
(the "Stockholder Notice Procedure").
 
     The Stockholder Notice Procedure provides that, subject to the rights of
any holders of Preferred Stock, only persons who are nominated by or at the
direction of the Board, any committee appointed by the Board, or by a
stockholder who has given timely written notice to the Secretary of the Company
prior to the meeting at which directors are to be elected, will be eligible for
election as directors of the Company. The Stockholder Notice Procedure provides
that at an annual meeting, only such business may be conducted as has been
brought before the meeting by, or at the direction of, the Board, any committee
appointed by the Board, or by a stockholder who has given timely written notice
to the Secretary of the Company of such stockholder's intention to bring such
business before such meeting. Under the Stockholder Notice Procedure, to be
timely, notice of stockholder nominations or proposals to be made at an annual
or special meeting must be received by the Company not less than 60 days nor
more than 90 days prior to the scheduled date of the meeting (or, if less than
70 days' notice or prior public disclosure of the date of the meeting is given,
then the 15th day following the earlier of: (i) the day such notice was mailed;
or (ii) the day such public disclosure was made).
 
     Under the Stockholder Notice Procedure, a stockholder's notice to the
Company proposing to nominate a person for election as director must contain
certain information about the nominating stockholder and the proposed nominee,
and a stockholder's notice relating to the conduct of business other than the
nomination of directors must contain certain information about such business and
about the proposing stockholder. If the Chairman or other officer presiding at a
meeting determines that a person was not nominated, or other business was not
brought before the meeting, in accordance with the Stockholder Notice Procedure,
such person will not be eligible for election as a director, or such business
will not be conducted at such meeting, as the case may be.
 
     By requiring advance notice of nominations by stockholders, the Stockholder
Notice Procedure affords the Board an opportunity to consider the qualifications
of the proposed nominees and, to the extent deemed necessary or desirable by the
Board, to inform stockholders about such qualifications. By requiring advance
notice of other proposed business, the Stockholder Notice Procedure also
provides a more orderly procedure for conducting annual meetings of stockholders
and, to the extent deemed necessary or desirable by the Board, provides the
Board with an opportunity to inform stockholders, prior to such meetings, of any
business proposed to be conducted at such meetings, together with any
recommendations as to the Board's position regarding action to be taken with
respect to such business, so that stockholders can better decide whether to
attend such a meeting or to grant a proxy regarding the disposition of any such
business.
 
                                       61
<PAGE>   63
 
     Although the Restated By-laws do not give the Board any power to approve or
disapprove stockholder nominations for the election of directors or proposals
for action, the forgoing provisions may have the effect of precluding a contest
for the election of directors or the consideration of stockholder proposals and
of discouraging or deterring a third party from conducting a solicitation of
proxies to elect its own slate of directors or to approve its own proposal, if
the proper advance notice procedures are not followed, without regard to whether
consideration of such nominees or proposals might be harmful or beneficial to
the Company and its stockholders.
 
     Certain Provisions Relating to Potential Change of Control. The Restated
Certificate authorizes the Board and any committee of the Board to take such
action as it may determine to be reasonably necessary or desirable to encourage
any person or entity to enter into negotiations with the Board and management
regarding any transaction which may result in a change of control of the
Company, or to contest or oppose any such transaction which the Board determines
to be unfair, abusive or otherwise undesirable to the Company, its business,
assets, properties or stockholders. The Board or any such committee is
specifically authorized to adopt plans or to issue securities of the Company
including plans, rights, options, capital stock, notes, debentures or other debt
securities, which securities may be exchangeable or convertible into cash or
other securities on such terms and conditions as the Board or any such committee
determines. In addition, the Board or such committee of the Board may provide
that any holder or class of holders of such designated securities will be
treated differently than, and unequally to, all other security holders in
respect of the terms, conditions, provisions and rights of such securities.
 
     The existence of this authority or the actions which may be taken by the
Board pursuant thereto are intended to give the Board flexibility in order to
act in the best interests of stockholders in the event of a potential change of
control transaction. Such provisions may, however, deter potential acquirors
from proposing unsolicited transactions not approved by the Board and might
enable the Board to hinder or frustrate such a transaction if proposed.
 
     Limitation of Liability of Directors. The Restated Certificate provides
that a director will not be personally liable to the Company or its stockholders
for monetary damages for any breach of fiduciary duty as a director, except 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 Delaware Law, which concerns unlawful payments of dividends,
stock purchases or redemptions; or (iv) for any transaction from which the
director derived an improper personal benefit. If the Delaware Law is
subsequently amended to permit further limitation of the personal liability of
directors, the liability of a director of the Company will be eliminated or
limited to the fullest extent permitted by the Delaware Law as so amended.
 
     Amendment of the Certificate of Incorporation and By-laws. The Restated
Certificate contains provisions requiring the affirmative vote of the holders of
at least 66 2/3% of the voting power of the Voting Stock to amend certain
provisions of the Restated Certificate (including the provisions discussed above
relating to the size and classification of the Board, replacement and/or removal
of Board members, action by written consent, special stockholder meetings, the
authorization for the Board to take steps to encourage or oppose, as the case
may be, transactions which may result in a change of control of the Company, and
limitation of the liability of directors) or to amend any provision of the
Restated By-laws by action of stockholders following the offering. These
provisions make it more difficult for stockholders to make changes in the
Restated Certificate and the Restated By-laws, including changes designed to
facilitate the exercise of control over the Company.
 
     Business Combination Provisions of Delaware Law. The Company is a Delaware
corporation and is subject to section 203 of the Delaware Law. In general,
section 203 prevents a Delaware corporation from engaging in a "business
combination" (as defined) with an "interested stockholder" (defined generally as
a person owning 15% or more of a corporation's outstanding voting stock or
affiliate or associate) for three years following the time such stockholder
became an
 
                                       62
<PAGE>   64
 
interested stockholder, unless: (i) before such person became an interested
stockholder, the board of directors of the corporation approved the business
combination or the transaction in which the interested stockholder became an
interested stockholder; (ii) upon consummation of the transaction that resulted
in the interested stockholder's becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding stock held by
directors who are also officers of the corporation and by employee stock plans
that do not provide employees with the rights to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer); or (iii) at or subsequent to the time such person became an interested
stockholder, the business combination was approved by the board of directors of
the corporation and authorized at a meeting of stockholders by the affirmative
vote of the holders of 66 2/3% of the outstanding voting stock of the
corporation not owned by the interested stockholder. Under section 203, the
restrictions described above also do not apply to certain business combinations
proposed by an interested stockholder following the announcement or notification
of one of certain extraordinary transactions involving the corporation and a
person who had not been an interested stockholder during the previous three
years or who became an interested stockholder with the approval of a majority of
the corporation's directors, if such extraordinary transaction is approved or
not opposed by a majority of the directors who were directors prior to any
person becoming an interested stockholder during the previous three years or
were recommended for election or elected to succeed such directors by a majority
of such directors.
 
TRANSFER AGENT AND REGISTRAR
 
     BankBoston, N.A., c/o Boston EquiServe, L.P., will serve as transfer agent
and registrar for the Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this offering, the Company will have 7,932,724 shares of
Common Stock outstanding. All of the shares offered hereby will be freely
saleable in the public market after completion of this offering, unless acquired
by affiliates of the Company. All of the shares outstanding prior to completion
of this offering are subject to contractual restrictions that prohibit the
stockholder from selling or otherwise disposing of shares for a period of 180
days after the date of this Prospectus without the prior written consent of BT
Alex. Brown Incorporated. After this 180-day period expires, 4,749,998 of the
currently outstanding shares will be eligible for resale in the public market
under Rule 144 promulgated under the Securities Act, an additional 1,000,000 of
the currently outstanding shares will become eligible for resale in the public
market in February 1999, an additional 132,726 of the currently outstanding
shares will become eligible for resale in the public market later in 1999, and
an additional 50,000 of the currently outstanding shares will become eligible
for resale in the public market ratably over three years, in each case subject
to the restrictions of Rule 144. Shares of Common Stock held by affiliates of
the Company will be subject to certain volume and other limitations discussed
below under Rule 144.
    
 
   
     The Company has agreed not to sell, contract to sell or otherwise dispose
of any shares of Common Stock for a period of 180 days after the date of this
Prospectus, except as consideration for business acquisitions, upon exercise of
currently outstanding stock options or warrants or upon the issuance of options
to employees, consultants and directors under the Company's 1997 Stock Option
Plan, and the exercise of such options, without the prior written consent of BT
Alex. Brown Incorporated.
    
 
   
     In general, under Rule 144, a person (or persons whose shares are
aggregated), including persons who may be deemed affiliates of the Company, who
has beneficially owned his or her shares for at least one year is entitled to
sell within any three-month period that number of shares which does not exceed
the greater of 1% of the outstanding shares of the Common Stock (79,327 shares
    
 
                                       63
<PAGE>   65
 
after completion of this offering) or the average weekly trading volume during
the four calendar weeks preceding each such sale. Sales under Rule 144 also are
subject to certain manner of sale provisions, notice requirements and the
availability of current public information about the Company. Under Rule 144(k),
a person (or persons whose shares are aggregated) who is not or has not been
deemed an "affiliate" of the Company for at least three months and who has
beneficially owned his or her shares for at least two years would be entitled to
sell such shares under Rule 144 without regard to the limitations discussed
above.
 
     There has been no public market for the Common Stock prior to this offering
and no assurance can be given that an active public market for the Common stock
will develop or be sustained after completion of this offering. Sales of
substantial amounts of the Common Stock, or the perception that such sales could
occur, could adversely affect the prevailing market price of the Common Stock
and could impair the Company's ability to raise capital or effect acquisitions
through the issuance of Common Stock.
 
     After the completion of this offering, the Company intends to file a
registration statement under the Securities Act to register all shares issuable
on exercise of stock options or other awards granted or to be granted under its
Stock Option Plan. After the filing of such registration statement and subject
to certain restrictions under Rule 144, those shares will be freely saleable in
the public market immediately following exercise of such options. The Company
currently intends to file a shelf registration statement covering up to an
additional 3,000,000 shares of Common Stock under the Securities Act, for its
use in connection with acquisitions that may be made by the Company. Such
shares, when issued, could be freely saleable in the public market 180 days
after the date of this Prospectus, or earlier on prior approval of BT Alex.
Brown Incorporated by persons not affiliated with the Company, unless the
Company contractually restricts their resale. See "Underwriting."

Underwriters named below (the "Underwriters"), through their Representatives, BT

Stock at the initial public offering price less the underwriting discounts and
commissions set forth on the cover page of this Prospectus:

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all of the shares of Common Stock offered hereby if
any of such shares are purchased.
 
     The Company has been advised by the Representatives of the Underwriters
that the Underwriters propose to offer the shares of Common Stock to the public
at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $          per share. The Underwriters may allow, and such dealers may
re-allow, a concession not in excess of $          per share to certain other
dealers. After commencement of the initial public offering, the offering price
and other selling terms may be changed by the Representatives of the
Underwriters.
 
     The Company has granted the Underwriters an option, exercisable not later
than 30 days after the date of this Prospectus, to purchase up to 300,000
additional shares of Common Stock at the initial public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the same
percentage thereof that the number of shares of Common Stock to be purchased by
it shown in the above table bears to the total number of shares offered by the
Company hereunder, and the Company will be obligated, pursuant to the option, to
sell such shares to the Underwriters. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the Common
Stock offered hereby. If purchased, such additional shares will be offered by
the Underwriters on the same terms as those on which the 2,000,000 shares are
being offered.
 
     To facilitate the offering of the Common Stock, the Underwriters may engage
in transactions that stabilize, maintain or otherwise affect the market price of
the Common Stock. Specifically, the Underwriters may over-allot shares of the
Common Stock in connection with the offering, thereby creating a short position
in the Underwriters' syndicate account. Additionally, to cover such over-
allotments or to stabilize the market price of the Common Stock, the
Underwriters may bid for, and purchase, shares of the Common Stock in the open
market. Any of these activities may maintain the market price of the Common
Stock at a level above that which might otherwise prevail in the open market.
The Underwriters are not required to engage in these activities, and, if
commenced, any such activities may be discontinued at any time. The
Representatives, on behalf of the syndicate of Underwriters, also may reclaim
selling concessions allowed to an Underwriter or dealer, if the syndicate
repurchases shares distributed by that Underwriter or dealer.
 
                                       65
<PAGE>   67
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
   
     The Company has agreed not to sell, contract to sell or otherwise dispose
of any shares of Common Stock for a period of 180 days after the date of this
Prospectus, except as consideration for business acquisitions, upon exercise of
currently outstanding stock options or warrants, or upon the issuance of options
to employees, consultants and directors under the Company's 1997 Stock Option
Plan, and the exercise of such options, without the prior written consent of BT
Alex. Brown Incorporated. All stockholders, directors and officers of the
Company have agreed not to sell, contract to sell or otherwise dispose of any
shares of Common Stock for a period of 180 days without the prior written
consent of BT Alex. Brown Incorporated.
    
 
     The Representatives of the Underwriters have advised the Company that they
do not intend to confirm sales to any account over which they exercise
discretionary authority.
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company. Consequently, the initial public offering price will be
determined by negotiations between the Company and the Representatives of the
Underwriters. Among the factors to be considered in such negotiations are
prevailing market conditions, the results of operations of the Company in recent
periods, the market capitalizations and stages of development of other companies
that the Company and the Representatives believe to be comparable to the
Company, estimates of the business potential of the Company, the present state
of the Company's development and other factors deemed relevant.
 
                                 LEGAL MATTERS
 
     The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Shartsis, Friese & Ginsburg LLP, San
Francisco, California. Certain legal matters related to this offering will be
passed upon for the Underwriters by Piper & Marbury L.L.P., Baltimore, Maryland.
The statements pertaining to the Company's G certificates awarded by the WUTC

                      INTRODUCTION TO UNAUDITED PRO FORMA
                       CONSOLIDATED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Consolidated Balance Sheet as of March
31, 1998 gives effect to this offering and the Unaudited Pro Forma Consolidated
Statements of Operations for the year ended December 31, 1997 and the three
months ended March 31, 1998, give effect to this offering and the business
combinations involving Waste Connections, Inc., (the "Company"), its
predecessors, Waste Connections of Idaho, Inc. ("WCII"), its predecessors and
Madera Disposal Systems, Inc. ("Madera"). Such combinations were accounted for
using the purchase method of accounting. The Unaudited Pro Forma Consolidated
Balance Sheet is presented as if this offering had occurred on March 31, 1998,
and the Pro Forma Consolidated Statements of Operations for the year ended
December 31, 1997 and for the three months ended March 31, 1998 are presented as
if this offering and the Company's acquisitions of its predecessors, WCII and
its predecessors and Madera had occurred as of January 1, 1997.
 
     The Company has preliminarily analyzed the savings that it expects to be
realized by consolidating certain operational and general and administrative
functions. The Company has not and cannot quantify all of these savings due to
the short period of time since the predecessor, Madera and WCII acquisitions
occurred. It is anticipated that these savings will be partially offset by the
costs of being a publicly held company and the incremental increase in costs
related to the Company's corporate management. However, these costs, like the
savings they offset, cannot be quantified accurately. Neither the anticipated
savings nor the anticipated costs have been included in the Unaudited Pro Forma
Consolidated Financial Statements.
 
     The Unaudited Pro Forma Consolidated Financial Statements include certain
adjustments to the historical combined financial statements of the predecessors,
including adjusting depreciation expense to reflect purchase price allocations,
reducing interest expense to reflect retirement of the outstanding
acquisition-related debt with the proceeds of this offering and the related
income tax effects of these adjustments.
 
     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions and may be revised as additional information
becomes available. The Unaudited Pro Forma Consolidated Financial Statements do
not purport to represent what the Company's financial position or results of
operations would actually have been if such transactions in fact had occurred on
those dates or to project the Company's financial position or results of
operations for any future period. Because the Company, its predecessors, Madera,
and WCII and its predecessors were not under common control or management for
all periods, historical combined results may not be comparable to, or indicative
of, future performance. The Unaudited Pro Forma Consolidated Financial
Statements should be read in conjunction with the other financial statements and
notes thereto included elsewhere in this Prospectus, as well as information
included under the headings "Selected Financial Data," "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Risk
Factors" included elsewhere herein.

     PRO FORMA ADJUSTMENTS. The following adjustments have been made to the
unaudited pro forma consolidated statements of operations:
 
     (a)  To eliminate BFI corporate environmental expense allocation related to
          BFI landfill closure costs which do not exist for the Company.
 
     (b)  To record amortization of the loss contract accrual that was recorded
          in connection with the acquisitions of the predecessor operations. The
          loss contract accrual is being amortized to operating expenses over
          the related terms of the loss contracts which range from 6 to 65
          months. The loss contract accrual represents the estimated incremental
          losses to the Company related to certain unfavorable contracts the
          Company acquired in connection with the acquisition of the predecessor
          operations.
 
   
     (c)  To reduce facilities lease expense to the amounts provided for in the
          sublease agreement entered into with BFI in connection with the
          acquisitions of the predecessor operations. The sublease agreement was
          directly attributable to, a required element of, and a condition to
          the closing of the acquisition.
    
 
     (d)  To reduce BFI corporate overhead expense allocations to the amount of
          corporate overhead currently being incurred by the Company.
 
     (e)  To eliminate consulting expenses incurred by BFI related to the
          acquisition of The Disposal Group which the Company did not assume in
          connection with the acquisitions of

          the predecessors. The non-assumption of the consulting agreement was
          directly attributable to, a required element of, and a condition to
          the closing of the acquisition.
    
 
     (f)  To increase depreciation for the increase in the property and
          equipment's carrying value to fair value.
 
     (g)  To decrease goodwill amortization for the lower goodwill amount
          recorded by the Company in connection with its acquisition of the
          predecessor operations.
 
     (h)  To eliminate the predecessor's interest expense and record interest
          expense on the debt obligations incurred by the Company in connection
          with the acquisitions of the predecessors.
 
     (i)  To record the estimated tax provision associated with the pro forma
          adjustments using the Company's estimated effective tax rate of 40%.
 
     (j)  To record an income tax benefit for the net operating loss incurred by
          the predecessors for the nine months ended September 30, 1997 using
          the Company's effective tax rate of 40%.
 
   
     (k)  To adjust officers' salaries to levels provided for in the new
          employment agreements which were directly attributable to, required
          elements of, and a condition to the closing of the Madera acquisition.
    
 
     (l)  To reduce depreciation for the reduction in the property and
          equipment's carrying value to fair value.
 
     (m)  To increase goodwill amortization for the increase in goodwill
          resulting from the Madera acquisition. Goodwill is being amortized
          over a term of 40 years.
 
     (n)  To eliminate interest expense associated with the outstanding debt
          obligations of Madera which were paid-off in connection with the
          acquisition.
 
     (o)  To record interest expense on the additional long-term debt
          obligations incurred by the Company in connection with the Madera
          acquisition.
 
     (p)  To eliminate all interest expense, as the offering proceeds will be
          used to pay off all outstanding debt obligations of the Company.
 
     (q)  To record income taxes for Madera, which was a subchapter S
          corporation for income tax purposes for all periods prior to its
          acquisition by the Company. The effective income tax rate used was
          38%.

     ACQUISITION COSTS. The Company incurred costs of $180 related to the Madera
acquisition, which have been factored into the purchase price. Costs incurred by
Madera were expensed as incurred.
 
     CONTINGENT PAYMENTS. In connection with the Madera acquisition the Company
is required to pay contingent consideration to certain former Madera
shareholders, subject to their involvement in specified events that give rise to
the consideration. No amounts related to these contingent payments have been
included in the pro forma financial statements as the events which would give
rise to such payments have not yet occurred.
 
     OTHER. The Professional Cleaning business of Madera ceased operations in
July 1997. This business had revenues of $193 and an operating loss of $215
during the year ended December 31, 1997.
 
     Shortly before the acquisition of the predecessor operations by the
Company, BFI amended a franchise agreement with a municipality which provided
for a reduction in the franchise fees. Had this amended franchise agreement been
in effect as of January 1, 1997, pro forma cost of operations would have been
approximately $135 lower during the year ended December 31, 1997.

            NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET
                      (IN THOUSANDS, EXCEPT SHARE AMOUNTS)
 
     ASSUMPTIONS. The unaudited pro forma consolidated balance sheet as of March
31, 1998 is presented as if the Company's initial public offering had occurred
on March 31, 1998.
 
     PRO FORMA ADJUSTMENTS. The following adjustments have been made to the
unaudited pro forma consolidated balance sheet to reflect the Company's initial
public offering:
 
          (1) Issuance of 2,000,000 shares of Common Stock with estimated net
              proceeds of $19,260
 
          (2) Pay-off of all outstanding debt obligations of the Company
              ($16,868) and accumulated preferred stock dividends ($123)
 
          (3) Conversion of 2,499,998 shares of redeemable Series A Preferred
              Stock into 2,499,998 shares of Common Stock which automatically
              converts upon the Company's initial public offering.
 
          (4) Reclassification of 1,000,000 shares of redeemable Common Stock to
              Common Stock since the Company's initial public offering will
              cause the redemption feature to be cancelled.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
Waste Connections, Inc.
 
     We have audited the accompanying financial statements of Waste Connections,
Inc. and Predecessors as of December 31, 1996 and 1997, and for each of the
three years in the period ended December 31, 1997 which appear on pages F-12
through F-19 herein as listed in the accompanying Index to Financial Statements.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Waste Connections, Inc. and
Predecessors at December 31, 1996 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles.

1. ORGANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Business
 
     Waste Connections, Inc. ("WCI" or "the Company") was incorporated in
Delaware on September 9, 1997 and commenced its operations on October 1, 1997
through the purchase of certain solid waste operations in Washington, as more
fully described below and in Note 2. The Company is a regional, integrated,
non-hazardous solid waste services company that provides collection, transfer,
disposal and recycling services to commercial, industrial and residential
customers.
 
  Basis of Presentation
 
     The consolidated financial statements of the Company include the accounts
of WCI and its wholly owned subsidiaries. All significant intercompany
transactions and balances have been eliminated in consolidation.
 
     The entities the Company acquired in September 1997 from Browning-Ferris
Industries, Inc. ("BFI") are collectively referred to herein as the Company's
predecessors. BFI acquired the predecessor operations at various times during
1995 and 1996, and prior to being acquired by BFI, the predecessors operated as
separate stand-alone businesses.
 
     During the periods in which the Company's predecessors operated as wholly
owned subsidiaries of BFI, they maintained intercompany accounts with BFI for
recording intercompany charges for costs and expenses, intercompany purchases of
equipment and additions under capital leases and intercompany transfers of cash,
among other transactions. It is not feasible to ascertain the amount of related
interest expense that would have been recorded in the historical financial
statements had the predecessors been operated as stand-alone entities. Charges
for interest expense were allocated to the Company's predecessors by BFI as
disclosed in the accompanying Statement of Operations. The interest expense
allocations from BFI are based on formulas that do not necessarily correspond
with the balances in the related intercompany accounts. Moreover, the financial
position and results of operations of the predecessors during this period may
not necessarily be indicative of the financial position or results of operations
that would have been realized had the predecessors been operated as stand-alone
entities. For the periods in which the predecessors operated as wholly owned
subsidiaries of BFI, the statements of operations include amounts allocated by
BFI to the predecessors for selling, general and administrative expenses based
on certain allocation methodologies.
 
     During the periods prior to their acquisition by BFI, the Company's
predecessors operated as separate stand-alone businesses. The acquisitions of
the predecessors by BFI were accounted for using the purchase method of
accounting, and the respective purchase prices were allocated to the fair values
of the assets acquired and liabilities assumed. Similarly, the Company's
acquisitions of the predecessors from BFI in September 1997 were accounted for
using the purchase method of accounting, and the purchase price was allocated to
the fair value of the assets acquired and liabilities assumed. Consequently, the
amounts of depreciation and amortization included in the statements of
operations for the periods presented reflect the changes in basis of the
underlying assets that were made as a result of the changes in ownership that
occurred during the periods presented. In addition, because the predecessor
companies operated independently and were not

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1997
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
  (INFORMATION RELATING TO MARCH 31, 1998 AND THE THREE MONTHS ENDED MARCH 31,
                          1997 AND 1998 IS UNAUDITED)
 
under common control or management during these periods, and because different
tax strategies may have influenced their results of operations, the data may not
be comparable to or indicative of their operating results after their
acquisition by BFI.
 
     Due to the manner in which BFI intercompany transactions were recorded as
described above, it is not feasible to present a detailed analysis of
transactions reflected in the net intercompany balance with BFI. The change in
the predecessors' combined intercompany balance with BFI (net of income (loss)
and initial investment in the acquired companies) was $642 and $2,142 during the
period ended December 31, 1996 and the nine months ended September 30, 1997,
respectively.
 
     The accompanying statements of operations and cash flows for the Company
and its predecessors for the years ended December 31, 1995, 1996 and 1997 are
comprised of the following entities for the periods indicated:

  Interim Financial Information
 
     The unaudited interim consolidated financial statements as of March 31,
1998 and for the three months ended March 31, 1997 and 1998 have been prepared
in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring adjustments) considered necessary for a fair presentation
have been included. Operating results for the three months ended March 31, 1998
are not necessarily indicative of the results that may be expected for the year
ended December 31, 1998.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
\   Common Stock Valuation
 
     In connection with the Company's organization and initial capitalization in
September 1997, the Company sold 2.3 million shares of common stock for $.01 per
share to certain directors, consultants, and management. As a result, the
Company recorded a non-recurring, non-cash stock compensation charge of $4,395
in the accompanying consolidated statement of operations, representing the
difference between the amount paid for the shares and the estimated fair value
of the shares of $1.92 per share on the date of sale. The estimated fair value
of the common shares was determined by the Company based on an independent
valuation of the common stock.
 
  Concentrations of Credit Risk
 
     Financial instruments that potentially subject the Company to
concentrations of credit risks consist primarily of accounts receivable. Credit
risk on accounts receivable is minimized as a result of the large and diverse
nature of the Company's customer base. The Company maintains an allowance for
losses based on the expected collectibility of accounts receivable. Credit
losses have been within management's expectations.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Improvements or betterments
which significantly extend the life of an asset are capitalized. Expenditures
for maintenance and repair costs are charged to operations as incurred. The cost
of assets retired or otherwise disposed of and the related accumulated
depreciation are eliminated from the accounts in the year of disposal. Gains and
losses resulting from property disposals are included in other income (expense).
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets.

                          1997 AND 1998 IS UNAUDITED)
 
     The estimated useful lives are as follows:
 
<TABLE>
<S>                              <C>
Machinery and equipment........  3 - 10 years
Rolling stock..................  10 years
Containers.....................  5 - 12 years
Furniture and fixtures.........  3 - 6 years
</TABLE>
 
     In connection with the BFI acquisitions (Note 2) the Company acquired
certain used property and equipment. This used property and equipment is being
depreciated using the straight-line method over its estimated remaining useful
lives, which range from one to nine years.
 
  Goodwill
 
     Goodwill represents the excess of the purchase price over the fair value of
the net assets of the acquired entities (Note 2), and is amortized on a
straight-line basis over the period of expected benefit of 40 years. Accumulated
amortization amounted to $279 and $64 as of December 31, 1996 and 1997,
respectively.
 
     The Company continually evaluates the value and future benefits of its
intangibles. The Company assesses recoverability from future operations using
income from operations of the related acquired business as a measure. Under this
approach, the carrying value would be reduced if it becomes probable that the
Company's best estimate for expected future cash flows of the related business
would be less than the carrying amount of the intangible over the remaining
amortization period. For the period ending December 31, 1997, there were no
adjustments to the carrying amounts of intangibles resulting from these
evaluations.
 
  Fair Value of Financial Instruments
 
     The carrying values of the line of credit (Note 5) and other long-term debt
(Note 6) approximate their fair values as of December 31, 1997 and March 31,
1998, based on current incremental borrowing rates for similar types of
borrowing arrangements.
 
  Income Taxes
 
     The Company, The Disposal Group, and Fibres International, Inc., use the
liability method to account for income taxes. Under this method, deferred tax
assets and liabilities are determined based on differences between the financial
reporting and tax bases of assets and liabilities and are measured using the
enacted tax rates and laws that will be in effect when the differences are
expected to reverse.
 
     During the periods in which the predecessors were owned by BFI, their
operations were included in the consolidated income tax returns of BFI, and no
allocations of income taxes were reflected in the historical statements of
operations. For purposes of the combined predecessor financial statements,
current and deferred income taxes have been provided on a separate income tax
return basis.

  Revenue Recognition
 
     Revenues are recognized as services are provided. Certain customers are
billed in advance and, accordingly, recognition of the related revenues is
deferred until the services are provided.
 
  Start-Up and Integration Expenses
 
     During the period from inception (September 9, 1997) through December 31,
1997, the Company incurred certain start-up expenses relating to the formation
of the Company, primarily for legal and other professional services, and the
costs associated with recruiting the Company's initial management team. In
addition, the Company incurred certain integration expenses relating to the
Acquisitions (Note 2). These start-up and integration expenses have been charged
to operations as incurred.
 
     As described in Note 9, the Company issued warrants during the period from
inception (September 9, 1997) through December 31, 1997 to a bank in connection
with a line of credit and term loan payable, and to certain directors and
stockholders of the Company in connection with their guarantee of certain of the
Company's debt obligations. The fair value of these warrants is being amortized
into interest expense. During the period from inception (September 9, 1997)
through December 31, 1997, $710 relating to these warrants is included in
interest expense in the accompanying statement of operations of the Company.
 
  Stock-Based Compensation
 
     As permitted under the provisions of Financial Accounting Standards No. 123
"Accounting for Stock Based Compensation" ("SFAS 123"), the Company has elected
to account for stock-based compensation using the intrinsic value method
prescribed by Accounting Principles Board's Opinion No. 25 "Accounting for Stock
Issued to Employees" ("APB 25"). Under the intrinsic value method, compensation
cost is the excess, if any, of the quoted market price or fair value of the
stock at the grant date or other measurement date over the amount an employee
must pay to acquire the stock. None of the predecessor entities awarded
stock-based compensation to employees. Consequently, the related disclosures in
the accompanying financial statements and notes relate solely to the Company.
 
  Per Share Information
 
     In 1997, the Financial Accounting Standards Board ("FASB")issued Statement
No. 128, Earnings per Share. Statement 128 replaced the calculation of primary
and fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts have been presented on the
basis set forth in Statement 128 (Note 11). Earnings per share data have not
been presented for the predecessor operations because such data is not
meaningful.
 
     Pro-forma basic net income (loss) per share is computed by dividing the net
income (loss) by the sum of the weighted average number of shares of common
stock outstanding and common

shares issuable upon the conversion of all outstanding shares of Redeemable
Convertible Preferred Stock (Note 8) as though such conversion occurred at the
beginning of the period.
 
     Pro-forma diluted net income per share is computed by dividing net income
by the sum of the weighted average number of shares of common stock outstanding,
common shares issuable upon conversion of all outstanding shares of Redeemable
Convertible Preferred Stock (Note 8) as though such conversion occurred at the
beginning of the period, and common shares issuable upon the exercise of
outstanding common stock options and warrants (calculated using the treasury
stock method.)
 
  Closure and Post-Closure Costs
 
     Because it does not currently own any landfills, the Company does not
accrue for estimated landfill closure and post-closure maintenance costs. The
Company may have material financial obligations relating to closure and
post-closure costs of any disposal facilities it may own or operate in the
future, and in such case the Company will provide accruals for future financial
obligations relating to closure and post-closure costs of its landfills
(generally for a term of 30 years after final closure of a landfill), based on
engineering estimates of consumption of permitted landfill airspace over the
useful life of any such landfill.
 
  New Accounting Pronouncements
 
     In February 1997, the FASB issued Statement No. 129, Disclosure of
Information about Capital Structure, which is effective for financial statements
for periods ending after December 15, 1997. This statement establishes standards
for disclosing information about an entity's capital structure. Adoption of
Statement 129 will have no impact on the Company's existing disclosures.
 
     In June 1997, the FASB issued Statement No. 130, Reporting Comprehensive
Income. Statement 130 establishes standards for reporting and disclosure of
comprehensive income and its components (revenues, expenses, gains, and losses)
in a full set of general-purpose financial statements. Statement 130, which is
effective for fiscal years beginning after December 15, 1997, requires
reclassification of financial statements for earlier periods to be provided for
comparative purposes. The Company anticipates that implementing the provisions
of Statement 130 will not have a significant impact on the Company's existing
disclosures.
 
     In June 1997, the FASB issued Statement No. 131, Disclosure About Segments
of an Enterprise and Related Information. Statement 131 establishes standards
for the way that public business enterprises report information about operating
segments. It also establishes standards for related disclosures about products
and services, geographic areas and major customers. Statement 131 is effective
for fiscal years beginning after December 15, 1997. In the initial year of
application, comparative information for earlier years must be restated. The
Company anticipates that implementing the provisions of Statement 131 will not
have a significant impact on the Company's existing disclosures.

 2. ACQUISITIONS
 
  Browning-Ferris Industries Related
 
     On September 29, 1997, the Company purchased all of the outstanding stock
of Browning-Ferris Industries of Washington, Inc. and Fibres International, Inc.
from BFI (collectively the "Acquisitions"). The total purchase price for the
Acquisitions was approximately $15,036, comprised principally of $11,493 in cash
and promissory notes payable to BFI totaling $3,543. Of the combined $15,036
purchase price, $9,578 was recorded as goodwill and $150 was assigned to a
non-competition agreement. The Acquisitions were accounted for in accordance
with the purchase method of accounting and, accordingly, the net assets acquired
were included in the Company's consolidated balance sheet based upon their
estimated fair values on the date of the Acquisitions. The Company's
consolidated statement of operations includes the revenues and expenses of the
acquired businesses after the effective date of the transaction.
 
     Certain items affecting the purchase price and the allocation are
preliminary. A summary of the preliminary purchase price allocation as of
December 31, 1997 for the Acquisitions is as follows:

     During the three months ended March 31, 1998, the Company increased the
accrual for losses on acquired contracts and goodwill by approximately $291 to
reflect revised estimates of additional losses on the acquired contracts that
are expected to be incurred.
 
  Waste Connections of Idaho, Inc.
 
     On January 30, 1998, the Company acquired all of the outstanding stock of
Waste Connections of Idaho, Inc. ("WCII") for $3 and the assumption of
liabilities in the amount of $1,943. WCII was owned by affiliates of the Company
and commenced operations in September 1997 through the purchase of certain solid
waste collection assets located in Eastern Idaho from Browning-Ferris of Idaho,
Inc. The acquisition has been accounted for in accordance with the purchase
method of accounting.

  Madera Disposal Systems, Inc.
 
     On February 23, 1998, the Company purchased all of the outstanding stock of
Madera Disposal Systems, Inc. ("Madera") effective February 1, 1998, pursuant to
a Stock Purchase Agreement (the "Agreement"). The Agreement requires the Company
to pay to the shareholders of Madera $9,579 in cash (a portion of which was used
to repay Madera outstanding debt on the date of acquisition and which is subject
to other adjustments as specified in the Agreement), 1,000,000 shares of the
Company's common stock with a fair market value of $7,500 (the "Stock"),
warrants to purchase 200,000 shares of the Company's common stock at $4.00 per
share with a fair market value of $954 (the "Warrants") and other contingent
consideration. The Agreement provides that in the event the Company does not
complete an initial public offering ("IPO") of its stock by March 31, 1999, with
aggregate gross proceeds of at least $5,000, the Company may be required to
repurchase the Stock and the Warrants from the former shareholders of Madera for
$2,800 in cash if certain other conditions are also met.
 
     The Madera acquisition has been accounted for in accordance with the
purchase method of accounting. The total purchase price and the excess of the
purchase price over the fair value of the net assets acquired in the Madera
acquisition were approximately $18,213 and $14,580, respectively.
 
     Certain items affecting the purchase price and the allocation are
preliminary. A summary of the preliminary purchase price allocation for the
Madera acquisition is as follows:

     Related to certain of the Acquisitions (Note 2), the Company acquired
certain long-term franchise agreements and contracts and entered into a
non-competition agreement. The estimated fair value of the acquired long-term
franchise agreements and contracts was determined by management based on the
discounted net cash flows associated with the agreements and contracts. The
amounts assigned to the franchise agreements and contracts is being amortized on
a straight-line method over the remaining term of the related agreements (11
years). The estimated fair value of the non-competition agreement was determined
by management based on the discounted adjusted operating income stream that
would have otherwise been subject to competition. The amount assigned to the
non-competition agreement is being amortized on a straight-line method

  Performance Bonds and Letters of Credit
 
     Municipal solid waste collection contracts may require performance bonds or
other means of financial assurance to secure contractual performance. As of
December 31, 1997, the Company had provided customers and various regulatory
authorities with bonds and letters of credit of approximately $800 to secure its
obligations. The Company's new credit facility (Note 12) provides for the
issuance of letters of credit in an amount up to $5,000, but any letters of
credit issued reduce the availability of borrowings for acquisitions or other
general corporate purposes. If the Company were unable to obtain surety bonds or
letters of credit in sufficient amounts or at acceptable rates, it

could be precluded from entering into additional municipal solid waste
collection contracts or obtaining or retaining landfill operating permits.
 
CONTINGENCIES
 
  Environmental Risks
 
     The Company is subject to liability for any environmental damage that its
solid waste facilities may cause to neighboring landowners or residents,
particularly as a result of the contamination of soil, groundwater or surface
water, and especially drinking water, including damage resulting from conditions
existing prior to the acquisition of such facilities by the Company. The Company
may also be subject to liability for any off-site environmental contamination
caused by pollutants or hazardous substances whose transportation, treatment or
disposal was arranged by the Company or its predecessors. Any substantial
liability for environmental damage incurred by the Company could have a material
adverse effect on the Company's financial condition, results of operations or
cash flows. As of December 31, 1997 and March 31, 1998, the Company is not aware
of any such environmental liabilities.
 
  Legal Proceedings
 
     In the normal course of its business and as a result of the extensive
governmental regulation of the solid waste industry, the Company may
periodically become subject to various judicial and administrative proceedings
involving federal, state or local agencies. In these proceedings, an agency may
seek to impose fines on the Company or to revoke or deny renewal of an operating
permit held by the Company. From time to time the Company may also be subject to
actions brought by citizens' groups or adjacent landowners or residents in
connection with the permitting and licensing of landfills and transfer stations,
or alleging environmental damage or violations of the permits and licenses
pursuant to which the Company operates.
 
     In addition, the Company may become party to various claims and suits
pending for alleged damages to persons and property, alleged violations of
certain laws and alleged liabilities arising out of matters occurring during the
normal operation of the waste management business. However, as of December 31,
1997 and March 31, 1998 there is no current proceeding or litigation involving
the Company that the Company believes will have a material adverse impact on the
Company's business, financial condition, results of operations or cash flows.
 
     During the period from January 1, 1996 through July 31, 1996, The Disposal
Group won a lawsuit against the city of Vancouver, Washington relating to the
city's annexation of certain territories served by The Disposal Group. The
Disposal Group received approximately $2.6 million from the lawsuit, which is
included in other income in the accompanying statement of operations.
 
  Employees
 
     Approximately 55 drivers and mechanics at the Company's Vancouver,
Washington operation are represented by the Teamsters Union, with which
Browning-Ferris Industries of Washington, Inc., the Company's predecessor in
Vancouver, entered a four-year collective bargaining agreement in January 1997.
In addition, in July 1997, the employees at the Company's facility in Issaquah,
Washington, adopted a measure to select a union to represent them in labor
negotiations with

management. The union and management are currently operating under a one-year
negotiating agreement, and, if those negotiations are unsuccessful, the earlier
date on which the union would be permitted to take additional action is July 27,
1998. Such additional action includes calling a strike or, if the Company
agrees, continuing to negotiate or commencing arbitration of the outstanding
issues. The Company is not aware of any other organizational efforts among its
employees and believes that its relations with its employees are good.
 
 8. REDEEMABLE CONVERTIBLE PREFERRED STOCK
 
     In September 1997, the Company received net proceeds of $6,992 from the
sale of 2,499,998 shares of redeemable convertible preferred stock (the
"Preferred Stock"). The Preferred Stock accrues cumulative dividends at the rate
of $.098 per share annually. Accumulated and unpaid dividends on Preferred Stock
amounted to $61 as of December 31, 1997. The Preferred Stock and any accumulated
and unpaid dividends are convertible at the holder's option into shares of the
Company's common stock at the calculated rate of $2.80 per share divided by the
"Conversion Price" subject to certain anti-dilution adjustments. As of December
31, 1997 and March 31, 1998, the Conversion Price was $2.80 per share. Each
share will automatically be converted into common stock immediately upon the
closing of a registered public offering of the Company's common stock with
proceeds to the Company of at least $5.00 per share and aggregate proceeds of at
least $5,000.
 
     Each share of Preferred Stock is redeemable, at the holder's option, during
the period from April 1, 1999 through October 1, 1999 for $4.20 per share plus
any accumulated and unpaid dividends. The difference between the carrying value
of the Preferred Stock and the redemption value (including accumulated
dividends) is being accreted using the interest method through the earliest
redemption date. The redemption of the Preferred Stock is not mandatory if it
would cause the Company to incur additional indebtedness or if it is prohibited
under any of the Company's then existing debt agreements.
 
     The preferred stockholders are entitled to one vote for each share of
common stock into which such shares can be converted, and are also entitled to
liquidation preferences equal to the greater of the initial purchase price per
share ($2.80) plus any accumulated and unpaid dividends, plus the greater of
$4.20 per share or an amount which equals an internal rate of return of 50% to
the investor. After receiving such preference, the holders of the preferred
stock share remaining proceeds with the common stockholders on an as converted
basis.

  Stockholder Notes Receivable
 
     In December 1997, the Company provided loans in the aggregate amount of $82
to certain employees, who are also common stockholders, for the purchase of
shares of the Company's Preferred Stock. The notes bear interest at 8%, are due
on January 1, 1999 and are secured by the Preferred Stock purchased and common
stock owned by the employees.
 
  Stock Options
 
     In November 1997, the Company's Board of Directors adopted a stock option
plan in which all officers, employees, directors and consultants may participate
(the "Option Plan"). Options granted under the Option Plan may either be
incentive stock options or nonqualified stock options (the "Options") and they
will generally have a term of 10 years from the date of grant and will vest over
periods determined at the date of grant. The exercise prices of the options are
determined by the Company's Board of Directors and will be at least 100% or 110%
of the fair market value of the Company's common stock on the date of grant as
provided for in the Option Plan.
 
   
     In connection with the Option Plan, the Company's Board of Directors
approved the reservation of 1,200,000 shares of common stock for issuance
thereunder. As of December 31, 1997 and March 31, 1998, no options to purchase
common stock were exercisable under the Option Plan. In addition, as of December
31, 1997 and March 31, 1998, options for 671,500 and 324,700 shares,
respectively of common stock were available for future grants under the Option
Plan.

     The weighted average remaining contractual life of stock options
outstanding as of December 31, 1997, was 9.4 years.
    
 
     Pro Forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its employee stock options under the fair value method of that Statement.
The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for the period from inception (September 9, 1997) through December
31, 1997: risk-free interest rate of 6%; dividend yield of zero; volatility
factor of the expected market price of the Company's common stock of .40; and a
weighted-average expected life of the option of 4 years.
 
     The Black-Scholes option valuation model was developed for us in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma net loss and pro forma basic net loss per share for the period from
inception (September 9, 1997) through December 31, 1997 were $(5,070) and
$(2.99) per share, respectively.
 
   
     During the three months ended March 31, 1998, the Company recorded deferred
stock compensation of $821 relating to stock options granted during the period
with exercise prices less than the estimated fair value of the Company's common
stock on the date of grant. The deferred stock compensation is being amortized
into expense over the vesting periods of the stock options which generally range
from 1 to 3 years. Compensation expense of $80 was recorded during the three
months ended March 31, 1998 relating to these options, and the remaining $741
will be amortized into expense in future periods.

  Stock Purchase Warrants
 
     In September 1997, the Company issued a warrant to purchase 200,000 shares
of the Company's common stock to the Bank that provided the Line and term loan
payable (Notes 5 and 6). The exercise price of the warrant is $.01 per share.
The warrant was valued at $382 on its date of issuance using the Black-Scholes
pricing model with an assumed stock price volatility of .40, risk-free interest
rate of 6.0%, estimated fair value of the common stock of $1.92 per share and an
expected life of 7 years. The value assigned to the warrant was reflected as a
discount on long-term debt. The discount was fully accreted to interest expense
using the straight-line method over the expected term of the debt agreements
(approximately three months).
 
     In connection with their guarantee of certain of the Company's debt
obligations (Notes 5 and 6), the Company issued warrants to purchase 841,000
shares of the Company's common stock to certain directors and stockholders of
the Company. The exercise price of the warrants is $2.80 per share. The warrants
were valued at $328 on their date of issuance using the Black-Scholes pricing
model with an assumed stock price volatility of .40, risk-free interest rate of
6.0%, estimated fair value of the common stock of $1.92 per share and expected
lives of 3 years. The value assigned to these warrants was fully amortized to
interest expense over the expected term of the debt agreements (approximately
three months).
 
     In December 1997, the Company issued to consultants warrants to purchase
15,000 shares of the Company's common stock. Warrants to purchase 10,000 and
5,000 shares of common stock had exercise prices of $5.00 per share and $2.80
per share, respectively.
 
   
     In February 1998, the Company granted warrants to an employee to purchase
50,000 shares of the Company's common stock at $2.80 per share. The Company
recorded stock compensation expense of approximately $235 relating to these
warrants.
    
 
  Initial Public Offering
 
     In December 1997, the Company's board of directors authorized the filing of
a registration statement with the Securities and Exchange Commission permitting
the Company to sell up to an aggregate of 2,300,000 shares of common stock
(including the underwriters' over-allotment option) to the public. Under the
terms of the offering currently contemplated, the Preferred Stock will be
converted into common stock, prior to or concurrently with the completion of the
offering, and the redemption provisions of the common stock issued in connection
with the Madera acquisition (Note 2) will expire.

     As of December 31, 1997, outstanding options to purchase 528,500 shares of
common stock (with exercise prices ranging from $2.80 to $10.50), outstanding
warrants to purchase 1,056,000 shares of common stock (with exercise prices from
$0.01 to $5.00), and the outstanding Redeemable Convertible Preferred Stock
could potentially dilute basic earnings per share in the future and have not
been included in the computation of diluted net loss per share because to do so
would have been antidilutive for the period presented.
 
12. NEW CREDIT FACILITY
 
     On January 30, 1998, the Company obtained a new revolving credit facility
from BankBoston (the "Credit Facility"). The maximum amount available under the
Credit Facility is $25,000 including stand-by letters-of-credit and the
borrowings will bear interest at various fixed and/or variable rates at the
Company's option. The Credit Facility allows for the Company to issue up to
$5,000 in stand-by letters-of-credit. The Credit Facility requires quarterly
payments of interest and it matures in January 2001. Borrowings under the Credit
Facility are secured by all of the Company's assets. The borrowings are further
secured by the shares of the Company's common and preferred stock owned by the
Company's President and Chief Executive Officer. The Credit Facility requires
the Company to pay an annual commitment fee equal to 0.5% of the unused portion
of the Credit Facility. The Credit Facility places certain business, financial
and operating restrictions on the

Company and it's subsidiaries including among other things, the incurrence of
additional indebtedness, investments, acquisitions, asset sales, mergers,
dividends, distributions and repurchases and redemptions of capital stock. The
Credit Facility also requires that specified financial ratios and balances be
maintained. In connection with the Credit Facility the Company granted to an
affiliate of BankBoston a warrant to purchase 140,000 shares of the Company's
common stock with an exercise price of $2.80 per share and an expiration date of
January 29, 2008.
 
13. RELATED PARTY TRANSACTIONS
 
     The Company has entered into certain transactions with Continental Paper,
LLC ("Continental"), in which the Company delivers to Continental all of the
Company's collected recyclable materials in areas in which Continental has
processing facilities and Continental pays the Company market rates for the
recyclable materials. Certain of the Company's stockholders are the majority
owners of Continental. During the period from inception (September 9, 1997)
through December 31, 1997, the Company received approximately $223 from
Continental in these transactions.
 
14. UNAUDITED PRO FORMA REDEEMABLE STOCK AND STOCKHOLDERS' EQUITY
 
     The Company's unaudited pro forma redeemable stock and stockholders' equity
as of March 31, 1998, gives effect to the conversion of the Preferred Stock into
2,499,998 shares of common stock. The conversion of the Preferred Stock into
common stock will occur prior to or concurrently with the completion of the
Company's initial public offering (Note 9). In addition, the redemption
provisions of the common stock issued in connection with the Madera acquisition
(Note 2) will expire upon completion of the initial public offering.

the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

                               DECEMBER 31, 1997
                                 (IN THOUSANDS)
 
 1. ORGANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION AND BUSINESS
 
     Madera Disposal Systems, Inc. ("Madera") is a regional, integrated,
non-hazardous solid waste services company that provides collection, transfer
disposal and recycling services to residential, commercial and industrial
customers. Madera Landfill is contracted by the County of Madera to operate the
Fairmead, the North Fork Transfer Station and the materials recovery facility
(aka, Mammoth Recycling Facility), all of which are located in the County of
Madera, State of California. Madera also holds an exclusive contract with the
County of Madera to collect solid waste within the unincorporated areas of the
County of Madera. The contracts continue in force and effect until August 2004,
and will automatically be extended for one five year period unless Madera is
then in material breach or default of its obligations under the materials
recovery facility contract. All contracts may be extended for additional periods
and upon terms as the County of Madera and Madera may mutually agree upon.
 
     On November 9, 1993, Madera entered into an agreement with the County of
Madera, whereby Madera was to design, permit, finance, construct, equip, staff,
operate and maintain a materials recovery facility (the "Facility") at the
County's Fairmead Landfill for the purpose of providing the County of Madera
with a guaranteed reduction in the quantity of municipal solid waste requiring
landfill disposal. The Facility was to be designed, constructed and operated to
receive all municipal solid waste from the Cities of Madera and Chowchilla and
the unincorporated areas of the County of Madera. It was also to meet the
twenty-five percent (25%) waste reduction requirements of Assembly Bill 939
(Chapter 1095 of the Statutes of 1989) for the Cities of Madera and Chowchilla
and the County of Madera by January 11, 1995, through the recycling of recovered
material, and work toward the waste reduction requirements of fifty percent
(50%) that each jurisdiction must achieve by January 1, 2000. The Facility
became operational on August 15, 1994.
 
     The County of Madera will compensate Madera for its capital costs incurred
in designing, permitting, financing, constructing and equipping the Facility.
These costs were $1,661 and are included in property and equipment in the
accompanying balance sheets. The County of Madera will reimburse Madera for the
equipment and interest costs over a ten year operational period. The County of
Madera will also reimburse Madera for its other operational costs incurred in
connection with the staffing, maintaining and operating of the materials
recovery facility. All of the aforementioned costs are reimbursed to Madera
through receipt of a specified portion of waste disposal fees collected by
Madera on behalf of the County of Madera for landfill operations.
 
     At the termination of the contracts described above, the improvements made
by Madera become the sole and exclusive property of the County of Madera,
subject only to the County of Madera's continuing obligation to pay or reimburse
the Company for any remaining unamortized capital costs of the Facility.
 
     In 1995, Madera started a new line of business which provided clean-up and
waste removal services to residential and commercial construction businesses.
Due to continued losses, in July 1997 Madera ceased operations in this line of
business. The estimated fair value of the remaining assets of the business is
reflected in the accompanying balance sheets as assets held for sale at December
31, 1997. For the years ended December 31, 1995, 1996, and 1997, this business
had revenues of $531, $785 and $193, respectively, and had operating losses of
$290, $397, and $215, respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1997
                                 (IN THOUSANDS)
 
     Madera entered into an exclusive franchise agreement with the City of
Chowchilla on April 8, 1996, whereby Madera was granted the exclusive right and
franchise to collect, haul, and dispose of all solid waste, recyclable solid
waste, and green waste within the city limits of the City of Chowchilla. The
term of this franchise shall continue in force and effect for a period of seven
years, and the City of Chowchilla may renew and extend the franchise for an
additional period of five years or more.
 
SALE OF THE COMPANY
 
     Effective February 1, 1998, Madera's shareholders entered into an agreement
to sell their stock to Waste Connections, Inc. ("WCI") for cash and stock in
WCI.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
CASH EQUIVALENTS
 
     Madera considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments that potentially subject Madera to concentrations of
credit risks consist primarily of accounts receivable. Credit risk on accounts
receivable is minimized as a result of the large and diverse nature of Madera's
customer base. Madera maintains an allowance for losses based on the expected
collectibility of accounts receivable. Credit losses have been within
management's expectations.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Improvements or betterments
which significantly extend the life of an asset are capitalized. Expenditures
for maintenance and repair costs are charged to operations as incurred. The cost
of assets retired or otherwise disposed of and the related accumulated
depreciation are eliminated from the accounts in the year of disposal. Gains and
losses resulting from property disposals are included in other income (expense).
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets or lease term, whichever is shorter.
 
     The estimated useful lives are as follows:

FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying values of cash and equivalents approximate their fair values
as of December 31, 1996 and 1997. The carrying values of the long-term debt and
capital lease obligations (Notes 3

and 4) approximate their fair values as of December 31, 1996 and 1997, based on
current incremental borrowing rates for similar types of borrowing arrangements.
 
REVENUE RECOGNITION
 
     Madera recognizes revenues as services are provided. Certain customers are
billed in advance and, accordingly, recognition of the related revenues is
deferred until the services are provided.
 
INCOME TAXES
 
     Madera operates under Subchapter S of the Internal Revenue Code for federal
and state income tax reporting purposes. Consequently, all of the income tax
attributes and liabilities of the Madera's operations flow through to the
individual shareholders.
 
CLOSURE AND POST-CLOSURE COSTS
 
     Under regulations pursuant to which the permit for the Fairmead Landfill
was issued, Madera and Madera County, as operator and owner, respectively, are
jointly liable for closure and post-closure liabilities with respect to the
landfill. Madera has not accrued for such liabilities because Madera County, as
required by state law, has established a special fund, into which a designated
portion of tipping fee surcharges are deposited, to pay such liabilities.
Consequently, management of Madera does not believe Madera has any financial
obligation for closure and post-closure costs for the Fairmead Landfill as of
December 31, 1997.

     Property and equipment as of December 31, 1996 and 1997 consists of the

operating leases during the years ended December 31, 1995, 1996 and 1997
amounted to $47, $41 and $33, respectively.
 
PERFORMANCE BONDS AND LETTERS OF CREDIT
 
     Municipal solid waste collection contracts may require performance bonds to
secure contractual performance. As of December 31, 1997, Madera had provided
customers and various regulatory authorities with bonds of approximately $200 to
secure its obligations. If Madera were unable to obtain surety bonds in
sufficient amounts or at acceptable rates, it could be precluded from entering
into additional municipal solid waste collection contracts or obtaining or
retaining landfill operating permits.
 
ENVIRONMENTAL RISKS
 
     Madera is subject to liability for any environmental damage that its solid
waste facilities may cause to neighboring 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 facilities
by Madera. Madera may also be subject to liability for any off-site
environmental contamination caused by pollutants or hazardous substances whose
transportation, treatment or disposal was arranged by Madera or its
predecessors. Any substantial liability for environmental damage incurred by
Madera could have a material adverse effect on Madera's financial condition,
results of operations or cash flows.
 
LEGAL PROCEEDINGS
 
     In the normal course of its business and as a result of the extensive
governmental regulation of the solid waste industry, Madera may periodically
become subject to various judicial and administrative proceeding involving
federal, state or local agencies. In these proceedings, an agency may seek to
impose fines on Madera or to revoke or deny renewal of an operating permit held
by Madera. From time to time Madera may also be subject to actions brought by
citizens' groups or adjacent landowners in connection with the permitting and
licensing of landfills and transfer

licenses pursuant to which Madera operates.
 
     In addition, Madera may become party to various claims and suits pending
for alleged damages to persons and property, alleged violations of certain laws
and alleged liabilities arising out of matters occurring during the normal
operation of the waste management business. However, as of December 31, 1997,
there is no current proceeding or litigation involving Madera that Madera
believes will have a material adverse impact on Madera's business, financial
condition, results of operations or cash flows.

</TABLE>
 
     The pro forma provisions for income taxes for the years ended December 31,
1995, 1996 and 1997 differ from the amounts computed by applying the applicable
statutory federal income tax rate (34%) to income before income taxes due to
state franchise taxes, certain non-deductible expenses and refundable tax
credits.
 
     Madera's pro forma deferred income tax asset of approximately $20 and $54
at December 31, 1996 and 1997, respectively, relates principally to differences
in the recognition of bad debt expenses, state franchise taxes and certain other
temporary differences. Madera also has pro forma deferred tax liabilities at
December 31, 1996 and 1997 of approximately $534 and $570, respectively, which
relate to differences between tax and financial methods of depreciation.
 
8. SUBSEQUENT EVENTS
 
     On January 12, 1998, Madera distributed $131 to its shareholders.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Amended and Restated Certificate of Incorporation (the "Restated
Certificate") of the Company provides that a director will not be personally
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director, except 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 Delaware General
Corporation Law (the "Delaware Law"), which concerns unlawful payments of
dividends, stock purchases or redemptions, or (iv) for any transaction from
which the director derived an improper personal benefit. If the Delaware Law is
subsequently amended to permit further limitation of the personal liability of
directors, the liability of a director of the Company will be eliminated or
limited to the fullest extent permitted by the Delaware Law as amended.
 
     Section 145(a) of the Delaware Law provides that 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 non 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 interest of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.
 
     Section 145(b) of the Delaware Law states that 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
 
                                      II-1
<PAGE>   123
 
request 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 is 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.
 
     Section 145(c) of the Delaware Law provides that 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
subsections (a) and (b) of section 145, 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.
 
     Section 145(d) of the Delaware Law states that any indemnification under
subsections (a) and (b) of section 145 (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 subsections (a) and (b). Such determination shall be made (i) by the
board of directors by a majority vote of a quorum consisting of directors who
were not parties to such action, suit or proceeding, or (ii) if such a quorum is
not obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders.
 
     Section 145(e) of the Delaware Law provides that 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 in section 145. 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.
 
     Section 145(f) of the Delaware Law states that the indemnification and
advancement of expenses provided by, or granted pursuant to, the other
subsections of section 145 shall not be deemed exclusive of any other rights to
which those seeking indemnification or advancement of expenses may be entitled
under any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.
 
     Section 145(g) of the Delaware Law provides that a corporation shall have
the power to purchase and maintain insurance on behalf of any person who is or
was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against any liability asserted against him and incurred by him in
any such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against such liability under
the provisions of section 145.
 
     Section 145(j) of the Delaware Law states that the indemnification and
advancement of expenses provided by, or granted pursuant to, section 145 shall,
unless otherwise provided when authorized or ratified, 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.

     Pursuant to Section 145 of the Delaware Law, the Registrant has purchased
insurance on behalf of its present and former directors and officers against any
liability asserted against or incurred by them in such capacity or arising out
of their status as such. The Company has entered into indemnification agreements
with each of its directors and officers providing for mandatory indemnification
and advancement of expenses to the maximum extent permitted by the Delaware Law.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     Set forth below is a listing of all sales by the Company of unregistered
securities since the Company was incorporated on September 9, 1997. All such
sales were exempt from registration under the Securities Act, pursuant to
Section 4(2) of the Securities Act (and, as noted below, Regulation D or Rule
701 thereunder), as they were transactions not involving a public offering. The
Company believes that each of the issuances made pursuant to Section 4(2) was
made to a sophisticated investor, who had the financial resources to bear the
risk of the investment and who had the means and opportunity to obtain
information concerning the Company. The consideration paid to the Company in
respect of each issuance was cash, unless otherwise indicated. All sales
described below were made by the Company without the assistance of any
underwriters.
 
          1. In September and October 1997, the Company in a private placement
     sold an aggregate of 2,300,000 shares of Common Stock at a price of $0.01
     per share and 2,499,998 shares of Series A Preferred Stock at a price of

     Regulation D promulgated under the Securities Act.
 
          2. In September 1997, the Company issued warrants to purchase 200,000

        3. In October and November 1997, the Company issued options to purchase

          4. In December 1997, the Company issued warrants to purchase an
     aggregate of 841,000 shares of Common Stock to the Company's directors and
     options to purchase 100,000 shares of Common Stock to Ronald J.
     Mittelstaedt. Such warrants and options have an exercise price of $2.80 per
     share and were issued pursuant to Regulation D under the Securities Act.
 
          5. In December 1997 and January 1998, the Company issued warrants to
     purchase an aggregate of 15,000 shares of Common Stock to three
     consultants, with an exercise price of $5.00 per share, and warrants to

     shares of Common Stock to BankBoston, N.A., at an exercise price of $2.80

     the Securities Act.
 
          7. In January and February 1998, the Company issued options to
     purchase 104,300 shares of Common Stock to various employees of the
     Company, at exercise prices ranging from $2.80 to $10.50 per share, and a
     weighted average exercise price of $5.27 per share. Such options were
     issued pursuant to Rule 701 and Regulation D under the Securities Act.
                                      II-3
<PAGE>   125

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities 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 Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for 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 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.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
     of this registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus 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.

BT Alex. Brown Incorporated
CIBC Oppenheimer Corp.
As Representatives of the
      Several Underwriters
c/o  BT Alex. Brown Incorporated
One South Street
Baltimore, Maryland 21202

Ladies and Gentlemen:

        Waste Connections, Inc., a Delaware corporation (the "Company"),
proposes to sell to the several underwriters (the "Underwriters") named in
Schedule I hereto for whom you are acting as representatives (the
"Representatives") an aggregate of 2,000,000 shares of the Company's Common
Stock, $0.01 par value (the "Firm Shares"). The respective amounts of the Firm
Shares to be so purchased by the several Underwriters are set forth opposite
their names in Schedule I hereto. The Company also proposes to sell at the
Underwriters' option an aggregate of up to 300,000 additional shares of the
Company's Common Stock (the "Option Shares") as set forth below.

        As the Representatives, you have advised the Company (a) that you are
authorized to enter into this Agreement on behalf of the several Underwriters,
and (b) that the several Underwriters are willing, acting severally and not
jointly, to purchase the numbers of Firm Shares set forth opposite their
respective names in Schedule I, plus their pro rata portion of the Option Shares
if you elect to exercise the over-allotment option in whole or in part for the
accounts of the several Underwriters. The Firm Shares and the Option Shares (to
the extent the 


                                      -1-


<PAGE>   2
aforementioned option is exercised) are herein collectively called the "Shares."

        In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

1.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

        The Company represents and warrants to each of the Underwriters as
follows:

        (a) A registration statement on Form S-1 (File No. 333-48029) with
respect to the Shares has been carefully prepared by the Company in conformity
with the requirements of the Securities Act of 1933, as amended (the "Act"), and
the Rules and Regulations (the "Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") thereunder and has been filed with the
Commission. Copies of such registration statement, including any amendments
thereto, the preliminary prospectuses (meeting the requirements of the Rules and
Regulations) contained therein and the exhibits, financial statements and
schedules, as finally amended and revised, have heretofore been delivered by the
Company to you. Such registration statement, together with any registration
statement filed by the Company pursuant to Rule 462(b) of the Act, herein
referred to as the "Registration Statement," which shall be deemed to include
all information omitted therefrom in reliance upon Rule 430A and contained in
the Prospectus referred to below, has become effective under the Act and no
post-effective amendment to the Registration Statement has been filed as of the
date of this Agreement. "Prospectus" means (a) the form of prospectus first
filed with the Commission pursuant to Rule 424(b) or (b) the last preliminary
prospectus included in the Registration Statement filed prior to the time it
becomes effective or filed pursuant to Rule 424(a) under the Act that is
delivered by the Company to the Underwriters for delivery to purchasers of the
Shares, together with the term sheet or abbreviated term sheet filed with the
Commission pursuant to Rule 424(b)(7) under the Act. Each preliminary prospectus
included in the Registration Statement prior to the time it becomes effective is
herein referred to as a "Preliminary Prospectus."

        (b) The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the State of Delaware, with
corporate power and authority to own or lease its properties and conduct its
business as described in the Registration Statement. Each of the subsidiaries of
the Company as listed in Exhibit 21 to Item 16(a) of the Registration Statement
(collectively, the "Subsidiaries") has been duly organized and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation, with corporate power and authority to own or lease its
properties and conduct its business as described in the Registration Statement.
The Subsidiaries are the only subsidiaries, direct or indirect, of the Company.
The Company and each of the Subsidiaries are duly qualified to transact business
in all jurisdictions in which the conduct of their business requires such
qualification and where the failure to so qualify would have a material adverse
effect on the Company and the Subsidiaries, taken as a whole. The outstanding
shares of capital stock of each of the Subsidiaries have been 


                                      -2-


<PAGE>   3
duly authorized and validly issued, are fully paid and non-assessable and, to
the extent shown in Exhibit A hereto, are owned by the Company or another
Subsidiary free and clear of all liens, encumbrances and equities and claims,
except, in the case of the Subsidiaries, liens in favor of BankBoston N.A., as
agent, to secure the obligations of the company and the Subsidiaries pursuant to
the Revolving Credit Agreement filed as Exhibit 10.1 to the Registration
Statement; and no options, warrants or other rights to purchase, agreements or
other obligations to issue or other rights to convert any obligations into
shares of capital stock or ownership interests in the Subsidiaries are
outstanding.

        (c) The outstanding shares of Common Stock of the Company have been duly
authorized and validly issued and are fully paid and non-assessable; the Shares
to be issued and sold by the Company have been duly authorized and when issued
and paid for as contemplated herein will be validly issued, fully paid and
non-assessable; and no preemptive rights of stockholders exist with respect to
any of the Shares or the issue and sale thereof. Neither the filing of the
Registration Statement nor the offering or sale of the Shares as contemplated by
this Agreement gives rise to any rights, other than those which have been waived
or satisfied, for or relating to the registration of any shares of Common Stock.

        (d) The information set forth under the caption "Capitalization" in the
Prospectus is true and correct. All of the Shares conform to the description
thereof contained in the Registration Statement. The form of certificates for
the Shares conforms to the corporate law of the jurisdiction of the Company's
incorporation.

        (e) The Commission has not issued an order preventing or suspending the
use of any Prospectus relating to the proposed offering of the Shares nor
instituted proceedings for that purpose. The Registration Statement contains,
and the Prospectus and any amendments or supplements thereto will contain, all
statements which are required to be stated therein by, and will conform to, the
requirements of the Act and the Rules and Regulations. The Registration
Statement and any amendment thereto do not contain, and will not contain, any
untrue statement of a material fact and do not omit, and will not omit, to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading. The Prospectus and any amendments and
supplements thereto do not contain, and will not contain, any untrue statement
of material fact; and do not omit, and will not omit, to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading;
provided, however, that the Company makes no representations or warranties as to
information contained in or omitted from 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 or on behalf of
any Underwriter through the Representatives, specifically for use in the
preparation thereof.

        (f) The consolidated financial statements of the Company and the
Subsidiaries, together with related notes and schedules as set forth in the
Registration Statement, present fairly the 


                                      -3-


<PAGE>   4
financial position and the results of operations and cash flows of the Company
and the consolidated Subsidiaries, at the indicated dates and for the indicated
periods. Such financial statements and related schedules have been prepared in
accordance with generally accepted principles of accounting, consistently
applied throughout the periods involved, except as disclosed herein (or as
described in the Registration Statement), and all adjustments necessary for a
fair presentation of results for such periods have been made. The summary
financial and statistical data relating to the Company included in the
Registration Statement presents fairly the information shown therein and such
data has been compiled on a basis consistent with the financial statements
presented therein and the books and records of the Company. The pro forma
financial information included in the Registration Statement and the Prospectus
present fairly the information shown therein, have been prepared in accordance
with the Commission's rules and guidelines with respect to pro forma financial
statements, have been properly compiled on the pro forma bases described
therein, and, in the opinion of the Company, the assumptions used in the
preparation thereof are reasonable and the adjustments used therein are
appropriate to give effect to the transactions or circumstances referred to
therein.

        (g) Ernst & Young, LLP, who have certified certain of the financial
statements filed with the Commission as part of the Registration Statement, are
independent public accountants as required by the Act and the Rules and
Regulations.

        (h) There is no action, suit, claim or proceeding pending or, to the
knowledge of the Company, threatened against the Company or any of the
Subsidiaries before any court or administrative agency or otherwise which, if
determined adversely to the Company or any of its Subsidiaries, might result in
any material adverse change in the earnings, business, management, properties,
assets, rights, operations, condition (financial or otherwise) or prospects of
the Company and of the Subsidiaries taken as a whole or to prevent the
consummation of the transactions contemplated hereby, except as set forth in the
Registration Statement.

        (i) The Company and the Subsidiaries have good and marketable title to
all of the properties and assets reflected in the consolidated financial
statements of the Company and the Subsidiaries (or as described in the
Registration Statement), subject to no lien, mortgage, pledge, charge or
encumbrance of any kind except those reflected in such financial statements (or
as described in the Registration Statement) or which are not material in amount.
The Company and the Subsidiaries occupy their leased properties under valid and
binding leases conforming in all material respects to the description thereof
set forth in the Registration Statement.

        (j) The Company and the Subsidiaries have filed all Federal, State and
local income tax returns which have been required to be filed and have paid all
taxes indicated by said returns and all assessments received by them or any of
them to the extent that such taxes have become due and are not being contested
in good faith. All tax liabilities have been adequately provided for in the
financial statements of the Company.


                                      -4-


<PAGE>   5
        (k) Since the respective dates as of which information is given in the
Registration Statement, as it may be amended or supplemented, there has not been
any material adverse change or any development involving a prospective material
adverse change in or affecting the earnings, business, management, properties,
assets, rights, operations, condition (financial or otherwise) or prospects of
the Company and its Subsidiaries taken as a whole, whether or not occurring in
the ordinary course of business, and there has not been any material transaction
entered into or any material transaction that is probable of being entered into
by the Company or the Subsidiaries, other than transactions in the ordinary
course of business and changes and transactions described in the Registration
Statement, as it may be amended or supplemented. The Company and the
Subsidiaries have no material contingent obligations which are not disclosed in
the Company's financial statements which are included in the Registration
Statement. The Company is not aware of (i) any material adverse change in or
affecting the validity of any of the G Certificates issued to it by the
Washington Utilities and Transportation Commission (the "WUTC"), (ii) any
material breach of, or noncompliance with, any of its G Certificates (iii) any
action or proposed action by the WUTC to cancel or suspend, or which could
reasonably be expected to result in the cancellation or suspension of, any of
its G Certificates or (iv) any action or proposed action by the State of
Washington or any of its municipalities regarding the annexation of previously
unincorporated territory covered by any of its G Certificates or any other
limitation of or reduction in the scope of the territory covered by any of its G
Certificates which action or proposed action would have a material adverse
effect on the Company and the Subsidiaries, taken as a whole.

        (l) Neither the Company nor any of the Subsidiaries is or with the
giving of notice or lapse of time or both, will be, in violation of or in
default under its Charter or By-Laws or under any agreement, lease, contract,
indenture or other instrument or obligation to which it is a party or by which
it, or any of its properties, is bound and which default is of material
significance in respect of the condition (financial or otherwise) of the Company
and its Subsidiaries taken as a whole or the business, management, properties,
assets, rights, operations, condition (financial or otherwise) or prospects of
the Company and the Subsidiaries taken as a whole. The execution and delivery of
this Agreement and the consummation of the transactions herein contemplated and
the fulfillment of the terms hereof will not conflict with or result in a breach
of any of the terms or provisions of, or constitute a default under, any
indenture, mortgage, deed of trust or other agreement or instrument to which the
Company or any Subsidiary is a party, or of the Charter or By-Laws of the
Company or any order, rule or regulation applicable to the Company or any
Subsidiary of any court or of any regulatory body or administrative agency or
other governmental body having jurisdiction.

        (m) Each approval, consent, order, authorization, designation,
declaration or filing by or with any regulatory, administrative or other
governmental body necessary in connection with the execution and delivery by the
Company of this Agreement and the consummation of the transactions herein
contemplated (except such additional steps as may be required by the 


                                      -5-


<PAGE>   6
Commission or the National Association of Securities Dealers, Inc. (the "NASD")
has been obtained or made and is in full force and effect.

        (n) The Company and each of the Subsidiaries holds all material
licenses, certificates and permits from governmental authorities, including G
Certificates issued by the WUTC, which are necessary to the conduct of their
businesses; and neither the Company nor any of the Subsidiaries has infringed
any patents, patent rights, trade names, trademarks or copyrights, which
infringement is material to the business of the Company and the Subsidiaries
taken as a whole. The Company knows of no material infringement by others of
patents, patent rights, trade names, trademarks or copyrights owned by or
licensed to the Company.

        (o) Neither the Company, nor to the Company's best knowledge, any of its
affiliates, has taken or may take, directly or indirectly, any action designed
to cause or result in, or which has constituted or which might reasonably be
expected to constitute, the stabilization or manipulation of the price of the
shares of Common Stock to facilitate the sale or resale of the Shares.

        (p) Neither the Company nor any Subsidiary is an "investment company"
within the meaning of such term under the Investment Company Act of 1940, as
amended (the "1940 Act") and the rules and regulations of the Commission
thereunder.

        (q) The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed
in accordance with management's general or specific authorization; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

        (r) The Company and each of its Subsidiaries carry, or are covered by,
insurance in such amounts and covering such risks as is adequate for the conduct
of their respective businesses and the value of their respective properties.

        (s) The Company is in compliance in all material respects with all
presently applicable provisions of the Employee Retirement Income Security Act
of 1974, as amended, including the regulations and published interpretations
thereunder ("ERISA"); no "reportable event" (as defined in ERISA) has occurred
with respect to any "pension plan" (as defined in ERISA) for which the Company
would have any liability; the Company has not incurred and does not expect to
incur liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the Internal
Revenue Code of 1986, as amended, including the regulations and published
interpretations thereunder (the "Code"); and each "pension plan" for which the
Company would have any liability that is intended to be 


                                      -6-


<PAGE>   7
qualified under Section 401(a) of the Code is so qualified in all material
respects and nothing has occurred, whether by action or by failure to act, which
would cause the loss of such qualification.

        (t) Except as described in the Prospectus, no labor dispute with the
employees of the Company or any of its Subsidiaries exists, or to the knowledge
of the Company, is threatened other than such disputes which would not
individually or in the aggregate, have a material adverse effect upon the
condition (financial or otherwise), business, management, properties, assets,
rights, operations or prospects of the Company.

2.      PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES.

        (a) On the basis of the representations, warranties and covenants herein

Option Shares at the price per share as set forth in the first paragraph of this
Section 2. The option granted hereby may be exercised in whole or in part by
giving written notice (i) at any time before the Closing Date and (ii) only once
thereafter within 30 days after the date of this Agreement, by you, as
Representatives of the several Underwriters, to the Company setting forth the
number of Option Shares as to which the several Underwriters are exercising the
option, the names and denominations in which the Option Shares are to be
registered and the time and date at which such certificates are to be delivered.
The time and date at which certificates for Option Shares are to be delivered
shall be determined by the Representatives but shall not be earlier than three
nor later than 10 full business days after the 


                                      -7-


<PAGE>   8
exercise of such option, nor in any event prior to the Closing Date (such time
and date being herein referred to as the "Option Closing Date"). If the date of
exercise of the option is three or more days before the Closing Date, the notice
of exercise shall set the Closing Date as the Option Closing Date. The number of
Option Shares to be purchased by each Underwriter shall be in the same
proportion to the total number of Option Shares being purchased as the number of
Firm Shares being purchased by such Underwriter bears to 2,000,000, adjusted by
you in such manner as to avoid fractional shares. The option with respect to the
Option Shares granted hereunder may be exercised only to cover over-allotments
in the sale of the Firm Shares by the Underwriters. You, as Representatives of
the several Underwriters, may cancel such option at any time prior to its
expiration by giving written notice of such cancellation to the Company. To the
extent, if any, that the option is exercised, payment for the Option Shares
shall be made on the Option Closing Date in same day funds via wire transfer to
the order of the Company against delivery of certificates therefor at the
offices of BT Alex. Brown Incorporated, 1 South Street, Baltimore, Maryland.

3. OFFERING BY THE UNDERWRITERS.

        It is understood that the several Underwriters are to make a public
offering of the Firm Shares as soon as the Representatives deem it advisable to
do so. The Firm Shares are to be initially offered to the public at the initial
public offering price set forth in the Prospectus. The Representatives may from
time to time thereafter change the public offering price and other selling
terms. To the extent, if at all, that any Option Shares are purchased pursuant
to Section 2 hereof, the Underwriters will offer them to the public on the
foregoing terms.

        It is further understood that you will act as the Representatives for
the Underwriters in the offering and sale of the Shares in accordance with a
Master Agreement Among Underwriters entered into by you and the several other
Underwriters.

4.      COVENANTS OF THE COMPANY.

        The Company covenants and agrees with the several Underwriters that:

        (a) The Company will (A) use its best efforts to cause the Registration
Statement to become effective or, if the procedure in Rule 430A of the Rules and
Regulations is followed, to prepare and timely file with the Commission under
Rule 424(b) of the Rules and Regulations a Prospectus in a form approved by the
Representatives containing information previously omitted at the time of
effectiveness of the Registration Statement in reliance on Rule 430A of the
Rules and Regulations and (B) not file any amendment to the Registration
Statement or supplement to the Prospectus of which the Representatives shall not
previously have been advised and furnished with a copy or to which the
Representatives shall have reasonably objected in writing or which is not in
compliance with the Rules and Regulations.


                                      -8-


<PAGE>   9
        (b) The Company will advise the Representatives promptly (A) when the
Registration Statement or any post-effective amendment thereto shall have become
effective, (B) of receipt of any comments from the Commission, (C) of any
request of the Commission for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information and (D) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the use of the Prospectus or of the institution of any
proceedings for that purpose. The Company will use its best efforts to prevent
the issuance of any such stop order preventing or suspending the use of the
Prospectus and to obtain as soon as possible the lifting thereof, if issued.

        (c) The Company will cooperate with the Representatives in endeavoring
to qualify the Shares for sale under the securities laws of such jurisdictions
as the Representatives may reasonably have designated in writing and will make
such applications, file such documents, and furnish such information as may be
reasonably required for that purpose, provided the Company shall not be required
to qualify as a foreign corporation or to file a general consent to service of
process in any jurisdiction where it is not now so qualified or required to file
such a consent. The Company will, from time to time, prepare and file such
statements, reports, and other documents, as are or may be required to continue
such qualifications in effect for so long a period as the Representatives may
reasonably request for distribution of the Shares.

        (d) The Company will deliver to, or upon the order of, the
Representatives, from time to time, as many copies of any Preliminary Prospectus
as the Representatives may reasonably request. The Company will deliver to, or
upon the order of, the Representatives during the period when delivery of a
Prospectus is required under the Act, as many copies of the Prospectus in final
form, or as thereafter amended or supplemented, as the Representatives may
reasonably request. The Company will deliver to the Representatives at or before
the Closing Date, four signed copies of the Registration Statement and all
amendments thereto including all exhibits filed therewith, and will deliver to
the Representatives such number of copies of the Registration Statement
(including such number of copies of the exhibits filed therewith that may
reasonably be requested), and of all amendments thereto, as the Representatives
may reasonably request.

        (e) The Company will comply with the Act and the Rules and Regulations,
and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
the rules and regulations of the Commission thereunder, so as to permit the
completion of the distribution of the Shares as contemplated in this Agreement
and the Prospectus. If during the period in which a prospectus is required by
law to be delivered by an Underwriter or dealer, any event shall occur as a
result of which, in the judgment of the Company or in the reasonable opinion of
the Underwriters, it becomes necessary to amend or supplement the Prospectus in
order to make the statements therein, in the light of the circumstances existing
at the time the Prospectus is delivered to a purchaser, not misleading, or, if
it is necessary at any time to amend or supplement the Prospectus to comply with
any law, the Company promptly will prepare and file with the Commission an
appropriate amendment to the Registration Statement or supplement to the


                                      -9-


<PAGE>   10
Prospectus so that the Prospectus as so amended or supplemented will not, in the
light of the circumstances when it is so delivered, be misleading, or so that
the Prospectus will comply with the law.

        (f) The Company will make generally available to its security holders,
as soon as it is practicable to do so, but in any event not later than 15 months
after the effective date of the Registration Statement, an earning statement
(which need not be audited) in reasonable detail, covering a period of at least
12 consecutive months beginning after the effective date of the Registration
Statement, which earning statement shall satisfy the requirements of Section
11(a) of the Act and Rule 158 of the Rules and Regulations and will advise you
in writing when such statement has been so made available.

        (g) The Company will, for a period of five years from the Closing Date,
deliver to the Representatives copies of annual reports and copies of all other
documents, reports and information furnished by the Company to its stockholders
or filed with any securities exchange pursuant to the requirements of such
exchange or with the Commission pursuant to the Act or the Exchange Act. The
Company will deliver to the Representatives similar reports with respect to
significant subsidiaries, as that term is defined in the Rules and Regulations,
which are not consolidated in the Company's financial statements.

        (h) No offering, sale, short sale or other disposition of any shares of
Common Stock of the Company or other securities convertible into or exchangeable
or exercisable for shares of Common Stock or derivative of Common Stock (or
agreement for such) will be made for a period of 180 days after the date of this
Agreement, directly or indirectly, by the Company otherwise than hereunder,
except as consideration for business acquisitions, [upon exercise of certain of
the currently outstanding options or warrants], upon the exercise or issuance of
options issued to employees, consultants and directors under the Company's 1997
Stock Option Plan to purchase up to 1,200,000 shares of the Company's Common
Stock or with the prior written consent of BT Alex. Brown Incorporated.

        (i) The Company will use its best efforts to have the Shares approved
for quotation on The Nasdaq National Market.

        (j) The Company has caused each officer, director and shareholder of the
Company to furnish to you, on or prior to the date of this agreement, a letter
or letters, in form and substance satisfactory to the Underwriters, pursuant to
which each such person shall agree not to offer, sell, sell short or otherwise
dispose of any shares of Common Stock of the Company or other capital stock of
the Company, or any other securities convertible, exchangeable or exercisable
for Common Stock or derivative of Common Stock owned by such person or request
the registration for the offer or sale of any of the foregoing (or as to which
such person has the right to direct the disposition of) for a period of 180 days
after the date of this Agreement, directly or indirectly, except with the prior
written consent of BT Alex. Brown Incorporated ("Lockup Agreements").


                                      -10-


<PAGE>   11
        (k) The Company shall apply the net proceeds of its sale of the Shares
as set forth in the Prospectus and shall file such reports with the Commission
with respect to the sale of the Shares and the application of the proceeds
therefrom as may be required in accordance with Rule 463 under the Act.

        (l) The Company shall not invest, or otherwise use the proceeds received
by the Company from its sale of the Shares in such a manner as would require the
Company or any of the Subsidiaries to register as an investment company under
the 1940 Act.

        (m) The Company will maintain a transfer agent and, if necessary under
the jurisdiction of incorporation of the Company, a registrar for the Common
Stock.

        (n) The Company will not take, directly or indirectly, any action
designed to cause or result in, or that has constituted or might reasonably be
expected to constitute, the stabilization or manipulation of the price of any
securities of the Company.

5.      COSTS AND EXPENSES.

        The Company will pay all costs, expenses and fees incident to the
performance of the obligations of the Company under this Agreement, including,
without limiting the generality of the foregoing, the following: accounting fees
of the Company; the fees and disbursements of counsel for the Company; the cost
of printing and delivering to, or as requested by, the Underwriters copies of
the Registration Statement, Preliminary Prospectuses, the Prospectus and this
Agreement; the Underwriters' Invitation Letter; the filing fees of the
Commission; the filing fee of the NASD; and the Listing Fee of The Nasdaq
National Market. The Company shall not, however, be required to pay for any of
the Underwriter's expenses (other than those related to qualification under NASD
regulation) except that, if this Agreement shall not be consummated because the
conditions in Section 6 hereof are not satisfied, or because this Agreement is
terminated by the Representatives pursuant to Section 11 hereof, or by reason of
any failure, refusal or inability on the part of the Company to perform any
undertaking or satisfy any condition of this Agreement or to comply with any of
the terms hereof on its part to be performed, unless such failure to satisfy
said condition or to comply with said terms be due to the default or omission of
any Underwriter, then the Company shall reimburse the several Underwriters for
reasonable out-of-pocket expenses, including fees and disbursements of counsel,
reasonably incurred in connection with investigating, marketing and proposing to
market the Shares or in contemplation of performing their obligations hereunder;
but the Company shall not in any event be liable to any of the several
Underwriters for damages on account of loss of anticipated profits from the sale
by them of the Shares.

6.      CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.

        The several obligations of the Underwriters to purchase the Firm Shares
on the Closing 


                                      -11-


<PAGE>   12
Date and the Option Shares, if any, on the Option Closing Date are subject to
the accuracy, as of the Closing Date or the Option Closing Date, as the case may
be, of the representations and warranties of the Company contained herein, and
to the performance by the Company of its covenants and obligations hereunder and
to the following additional conditions:

        (a) The Registration Statement and all post-effective amendments thereto
shall have become effective and any and all filings required by Rule 424 and
Rule 430A of the Rules and Regulations shall have been made, and any request of
the Commission for additional information (to be included in the Registration
Statement or otherwise) shall have been disclosed to the Representatives and
complied with to their reasonable satisfaction. No stop order suspending the
effectiveness of the Registration Statement, as amended from time to time, shall
have been issued and no proceedings for that purpose shall have been taken or,
to the knowledge of the Company, shall be contemplated by the Commission and no
injunction, restraining order or order of any nature by a Federal or state court
of competent jurisdiction shall have been issued as of the Closing Date which
would prevent the issuance of the Shares.

        (b) The Representatives shall have received on the Closing Date or the
Option Closing Date, as the case may be, the opinions of Shartsis, Friese &
Ginsburg LLP, counsel for the Company, dated the Closing Date or the Option
Closing Date, as the case may be, addressed to the Underwriters (and stating
that it may be relied upon by counsel to the Underwriters) to the effect that:

               (i) The Company has been duly organized and is validly existing
as a corporation in good standing under the laws of the State of Delaware, with
corporate power and authority to own or lease its properties and conduct its
business as described in the Registration Statement; each of the Subsidiaries
has been duly organized and is validly existing as a corporation in good
standing under the laws of the jurisdiction of its incorporation, with corporate
power and authority to own or lease its properties and conduct its business as
described in the Registration Statement; the Company and each of the
Subsidiaries are duly qualified to transact business in all jurisdictions in
which the conduct of their business requires such qualification, and in which
the failure to qualify would have a materially adverse effect upon the business
of the Company and the Subsidiaries taken as a whole; and the outstanding shares
of capital stock of each of the Subsidiaries have been duly authorized and
validly issued and are fully paid and non-assessable and are owned by the
Company or a Subsidiary; and, to the best of such counsel's knowledge, the
outstanding shares of capital stock of each of the Subsidiaries is owned free
and clear of all liens, encumbrances and equities and claims, except, in the
case of the Subsidiaries, liens in favor of BankBoston N.A., as agent, to secure
the obligations of the Company and the subsidiaries pursuant to the Revolving
Credit Agreement filed as Exhibit 10.1 to the Registration Statement, and no
options, warrants or other rights to purchase, agreements or other obligations
to issue or other rights to convert any obligations into any shares of capital
stock or of ownership interests in the Subsidiaries are outstanding.


                                      -12-


<PAGE>   13

set forth under the caption "Capitalization" in the Prospectus; the authorized
shares of the Company's Common Stock have been duly authorized; the outstanding
shares of the Company's Common Stock have been duly authorized and validly
issued and are fully paid and non-assessable; all of the Shares conform to the

exist with respect to any of the Shares or the issue or sale thereof.

               (iii) Except as described in or contemplated by the Prospectus,
to the knowledge of such counsel, there are no outstanding securities of the
Company convertible or exchangeable into or evidencing the right to purchase or
subscribe for any shares of capital stock of the Company and there are no
outstanding or authorized options, warrants or rights of any character
obligating the Company to issue any shares of its capital stock or any
securities convertible or exchangeable into or evidencing the right to purchase

Prospectus, to the knowledge of such counsel, no holder of any securities of the
Company or any other person has the right, contractual or otherwise, which has
not been satisfied or effectively waived, to cause the Company to sell or
otherwise issue to them, or to permit them to underwrite the sale of, any of the
Shares or the right to have any Common Stock or other securities of the Company
included in the Registration Statement or the right, as a result of the filing
of the Registration Statement, to require registration under the Act of any
shares of Common Stock or other securities of the Company.

               (iv) The Registration Statement has become effective under the
Act and, to the best of the knowledge of such counsel, no stop order proceedings
with respect thereto have been instituted or are pending or threatened under the
Act.

               (v) The Registration Statement, the Prospectus and each amendment
or supplement thereto comply as to form in all material respects with the
requirements of the Act and the applicable rules and regulations thereunder
(except that such counsel need express no opinion as to the financial statements
and related schedules therein).

               (vi) The statements under the captions "Business -- Regulation
(except that such counsel need express no opinion as to matters of Washington
Law)," "Management-Employment Agreements," "Certain Transactions," "Description
of Capital Stock" and "Shares Eligible for Future Sale" in the Prospectus,
insofar as such statements constitute a summary of documents referred to therein
or matters of law, fairly summarize in all material respects the information
called for with respect to the Act.

               (vii) Such counsel does not know of any contracts or documents
required to be 


                                      -13-


<PAGE>   14
filed as exhibits to the Registration Statement or described in the Registration

such contracts and documents as are summarized in the Registration Statement or
the Prospectus are fairly summarized in all material respects.

               (viii) Such counsel knows of no material legal or governmental
proceedings pending or threatened against the Company or any of the Subsidiaries
except as set forth in the Prospectus.

               (ix) The execution and delivery of this Agreement and the
consummation of the transactions herein contemplated do not and will not
conflict with or result in a breach of any of the terms or provisions of, or
constitute a default under, the Charter or By-Laws of the Company, or any
agreement or instrument known to such counsel to which the Company or any of the
Subsidiaries is a party or by which the Company or any of the Subsidiaries may
be bound.

               (x) This Agreement has been duly authorized, executed and
delivered by the Company.

               (xi) No approval, consent, order, authorization, designation,
declaration or filing by or with any regulatory, administrative or other
governmental body is necessary in connection with the execution and delivery of
this Agreement and the consummation of the transactions herein contemplated
(other than as may be required by the NASD as to which such counsel need express
no opinion) except such as have been obtained or made, specifying the same.

               (xii) The Company is not, and will not become, as a result of the
consummation of the transactions contemplated by this Agreement, and application
of the net proceeds therefrom as described in the Prospectus, required to
register as an investment company under the 1940 Act.

        In rendering such opinion Shartsis, Friese & Ginsburg LLP may rely as to
matters governed by the laws of states other than Delaware or Federal laws on
local counsel in such jurisdictions, provided that in each case Shartsis, Friese
& Ginsburg LLP shall state that they believe that they and the Underwriters are
justified in relying on such other counsel. In addition to the matters set forth
above, such opinion shall also include a statement to the effect that nothing
has come to the attention of such counsel which leads them to believe that (i)
the Registration Statement, at the time it became effective under the Act (but
after giving effect to any modifications incorporated therein pursuant to Rule
430A under the Act) and as of the Closing Date or the Option Closing Date, as
the case may be, contained an untrue statement of a material fact or omitted to


                                      -14-


<PAGE>   15
state a material fact required to be stated therein or necessary to make the
statements therein not misleading and (ii) the Prospectus, or any supplement
thereto, on the date it was filed pursuant to the Rules and Regulations and as
of the Closing Date or the Option Closing Date, as the case may be, contained an
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements, in the light of the circumstances
under which they are made, not misleading (except that such counsel need express
no view as to financial statements, schedules and statistical information
therein). With respect to such statement, Shartsis, Friese & Ginsburg LLP may
state that their belief is based upon the procedures set forth therein, but is
without independent check and verification.

        (c) The Representatives shall have received on the Closing Date or the
Option Closing Date, as the case may be, the opinion of Williams, Kastner &
Gibbs PLLC, special counsel for the Company, dated the Closing Date or the
Option Closing Date, as the case may be, addressed to the Underwriters (and
stating that it may be relied upon by counsel to the Underwriters) to the effect
that:

               (i) Based on an examination of the appropriate documents, the
Company holds the G Certificates awarded to it (or to its predecessors) by the
WUTC, as referenced in the Registration Statement or the Prospectus as necessary
to conduct regulated solid waste services in the State of Washington as
described in the Prospectus.

               (ii) Pursuant to the Company's G Certificates, the Company has
the exclusive right, by virtue the issuance by the WUTC of the Company's G
Certificates to transport solid waste, as defined by applicable Washington
regulation, in various areas of the State of Washington, subject only to (1) the
right of municipalities to annex previously unincorporated territory covered by
the G certificates; (2) cancellation or suspension by order of the WUTC after
complaint and hearing processes; (3) overlapping authority, if any, granted by
the WUTC, if existing service is found not to be to the satisfaction of the
WUTC, which standard has been construed as a difficult threshold to be met for
overlapping authority to be issued; and (4) action by the state or federal
legislatures which revises, alters or eliminates the underlying intrastate solid
waste certificate scheme.

               (iii) Such counsel has no reason to believe that any of the
Company's G Certificates will be suspended or canceled.

               (iv) The statements under the captions "Risk Factors -- Highly
Competitive Industry," "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Results of Operations -- General,"
"Business -- Industry Overview," and " -- G Certificates" in the Prospectus,
insofar as such statements constitute a summary of documents referred to therein
or matters of law relating to G Certificates issued by the WUTC, are accurate
summaries and fairly and correctly present the information called for with
respect to the Act.

        (d) The Representatives shall have received from Piper & Marbury L.L.P.,
counsel for the Underwriters, an opinion dated the Closing Date or the Option
Closing Date, as the case may be, substantially to the effect specified in
subparagraphs (ii), (iii), (iv) and (x) of Paragraph (b) of 


                                      -15-


<PAGE>   16
this Section 6, and that the Company is a duly organized and validly existing
corporation under the laws of the State of Delaware. In rendering such opinion,
Piper & Marbury L.L.P. may rely as to all matters governed other than by the
laws of the State of Delaware or Federal laws on the opinions of counsel
referred to in Paragraphs (b) and (c) of this Section 6. In addition to the
matters set forth above, such opinion shall also include a statement to the
effect that nothing has come to the attention of such counsel which leads them
to believe that (i) the Registration Statement, or any amendment thereto, as of
the time it became effective under the Act (but after giving effect to any
modifications incorporated therein pursuant to Rule 430A under the Act) as of
the Closing Date or the Option Closing Date, as the case may be, 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 (ii) the Prospectus, or any supplement thereto, on the date it was filed
pursuant to the Rules and Regulations and as of the Closing Date or the Option
Closing Date, as the case may be, contained an untrue statement of a material
fact or omitted to state a material fact, necessary in order to make the
statements, in the light of the circumstances under which they are made, not
misleading (except that such counsel need express no view as to financial
statements, schedules and statistical information therein). With respect to such
statement, Piper & Marbury L.L.P. may state that their belief is based upon the
procedures set forth therein, but is without independent check and verification.

        (e) You shall have received, on each of the dates hereof, the Closing
Date and the Option Closing Date, as the case may be, a letter dated the date
hereof, the Closing Date or the Option Closing Date, as the case may be, in form
and substance satisfactory to you, of Ernst & Young LLP confirming that they are
independent public accountants within the meaning of the Act and the applicable
published Rules and Regulations thereunder and stating that, in their opinion,
the financial statements and schedules examined by them and included in the
Registration Statement comply in form in all material respects with the
applicable accounting requirements of the Act and the related published Rules
and Regulations; and containing such other statements and information as is
ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial and statistical
information contained in the Registration Statement and Prospectus.

        (f) The Representatives shall have received on the Closing Date or the
Option Closing Date, as the case may be, a certificate or certificates of the
Chief Executive Officer and the Chief Financial Officer of the Company to the
effect that, as of the Closing Date or the Option Closing Date, as the case may
be, each of them severally represents as follows:

               (i) The Registration Statement has become effective under the Act
and no stop order suspending the effectiveness of the Registration Statement has
been issued, and no proceedings for such purpose have been taken or are, to his
knowledge, contemplated by the Commission;

               (ii) The representations and warranties of the Company contained
in Section 1 


                                      -16-


<PAGE>   17
hereof are true and correct as of the Closing Date or the Option Closing Date,
as the case may be;

               (iii) All filings required to have been made pursuant to Rules
424 or 430A under the Act have been made;

               (iv) He has carefully examined the Registration Statement and the
Prospectus and, in his opinion, as of the effective date of the Registration
Statement, the statements contained in the Registration Statement were true and
correct, and such Registration Statement and Prospectus did not omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein not misleading, and since the effective date of the
Registration Statement, no event has occurred which should have been set forth
in a supplement to or an amendment of the Prospectus which has not been so set
forth in such supplement or amendment; and

               (v) Since the respective dates as of which information is given
in the Registration Statement and Prospectus, there has not been any material
adverse change or any development involving a prospective material adverse
change in or affecting the condition, financial or otherwise, of the Company and
its Subsidiaries taken as a whole or the earnings, business, management,
properties, assets, rights, operations, condition (financial or otherwise) or
prospects of the Company and the Subsidiaries taken as a whole, whether or not
arising in the ordinary course of business.

        (g) The Company shall have furnished to the Representatives such further
certificates and documents confirming the representations and warranties,
covenants and conditions contained herein and related matters as the
Representatives may reasonably have requested.

        (h) The Firm Shares and Option Shares, if any, have been approved for
designation upon notice of issuance on The Nasdaq National Market.

        (i) The Lockup Agreements described in Section 4(j) are in full force
and effect.

        The opinions and certificates mentioned in this Agreement shall be
deemed to be in compliance with the provisions hereof only if they are in all
material respects satisfactory to the Representatives and to Piper & Marbury
L.L.P., counsel for the Underwriters.

        If any of the conditions hereinabove provided for in this Section 6
shall not have been fulfilled when and as required by this Agreement to be
fulfilled, the obligations of the Underwriters hereunder may be terminated by
the Representatives by notifying the Company of such termination in writing or
by telegram at or prior to the Closing Date or the Option Closing Date, as the
case may be.

        In such event, the Company and the Underwriters shall not be under any
obligation to each other (except to the extent provided in Sections 5 and 8
hereof).

7.      CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.

        The obligations of the Company to sell and deliver the portion of the
Shares required to be delivered as and when specified in this Agreement are
subject to the conditions that at the Closing Date or the Option Closing Date,
as the case may be, no stop order suspending the effectiveness of the
Registration Statement shall have been issued and in effect or proceedings
therefor initiated or threatened.

8.      INDEMNIFICATION.

        (a) The Company agrees to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of the
Act, against any losses, claims, damages or liabilities to which such
Underwriter or any such controlling person may become subject under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement of any material fact contained in the
Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto, or (ii) 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 each Underwriter and
each such controlling person upon demand for any legal or other expenses
reasonably incurred by such Underwriter or such controlling person in connection
with investigating or defending any such loss, claim, damage or liability,
action or proceeding or in responding to a subpoena or governmental inquiry
related to the offering of the Shares, whether or not such Underwriter or
controlling person is a party to any action or proceeding; provided, however,
that the Company will 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, any Preliminary Prospectus, the Prospectus, or such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or through the Representatives
specifically for use in the preparation thereof. This indemnity agreement will
be in addition to any liability which the Company may otherwise have.

        (b) Each Underwriter severally and not jointly will indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement and each person, if any, who controls the
Company within the meaning of the Act, against any losses, claims, damages or
liabilities to which the Company or any such director, officer or controlling
person may become subject under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or
(ii) the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the 


                                      -18-


<PAGE>   19
light of the circumstances under which they were made; and will reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer or controlling person in connection with investigating or defending any
such loss, claim, damage, liability, action or proceeding; provided, however,
that each Underwriter will be liable in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission has been made in the Registration Statement, any Preliminary
Prospectus, the Prospectus or such amendment or supplement, in reliance upon and
in conformity with written information furnished to the Company by or through
the Representatives specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which such Underwriter
may otherwise have.

        (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to this Section 8, such person (the "indemnified party") shall
promptly notify the person against whom such indemnity may be sought (the
"indemnifying party") in writing. No indemnification provided for in Section
8(a) or (b) shall be available to any party who shall fail to give notice as
provided in this Section 8(c) if the party to whom notice was not given was
unaware of the proceeding to which such notice would have related and was
materially prejudiced by the failure to give such notice, but the failure to
give such notice shall not relieve the indemnifying party or parties from any
liability which it or they may have to the indemnified party for contribution or
otherwise than on account of the provisions of Section 8(a) or (b). In case any
such proceeding 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, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party and
shall pay as incurred the fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to retain its own counsel at its own expense. Notwithstanding the foregoing, the
indemnifying party shall pay as incurred (or within 30 days of presentation) the
fees and expenses of the counsel retained by the indemnified party in the event
(i) the indemnifying party and the indemnified party shall have mutually agreed
to the retention of such counsel, (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them or
(iii) the indemnifying party shall have failed to assume the defense and employ
counsel acceptable to the indemnified party within a reasonable period of time
after notice of commencement of the action. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm for all such indemnified parties. Such
firm shall be designated in writing by you in the case of parties indemnified
pursuant to Section 8(a) and by the Company in the case of parties indemnified
pursuant to Section 8(b). The indemnifying party shall not be liable for any
settlement of any proceeding effected without 


                                      -19-


<PAGE>   20
its written consent but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. In addition, the indemnifying party will not, without
the prior written consent of the indemnified party, settle or compromise or
consent to the entry of any judgment in any pending or threatened claim, action
or proceeding of which indemnification may be sought hereunder (whether or not
any indemnified party is an actual or potential party to such claim, action or
proceeding) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action or proceeding.

        (d) If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under Section 8(a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
or proceedings 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 or
proceedings in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law, 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 Underwriters on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, (or actions or proceedings in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the Prospectus. The relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement 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 Underwriters 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 Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 8(d). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 8(d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party 


                                      -20-


<PAGE>   21
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (d), (i) no Underwriter shall
be required to contribute any amount in excess of the underwriting discounts and
commissions applicable to the Shares purchased by such Underwriter and (ii) 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. The Underwriters' obligations in
this Section 8(d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

        (e) In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 8 hereby
consents to the jurisdiction of any court having jurisdiction over any other
contributing party, agrees that process issuing from such court may be served
upon him or it by any other contributing party and consents to the service of
such process and agrees that any other contributing party may join him or it as
an additional defendant in any such proceeding in which such other contributing
party is a party.

        (f) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 8 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its directors or officers or any persons
controlling the Company, (ii) acceptance of any Shares and payment therefor
hereunder and (iii) any termination of this Agreement. A successor to any
Underwriter, or to the Company, its directors or officers or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 8.

9.      DEFAULT BY UNDERWRITERS.

        If on the Closing Date or the Option Closing Date, as the case may be,
any Underwriter shall fail to purchase and pay for the portion of the Shares
which such Underwriter has agreed to purchase and pay for on such date
(otherwise than by reason of any default on the part of the Company), you, as
Representatives of the Underwriters, shall use your reasonable efforts to
procure within 36 hours thereafter one or more of the other Underwriters, or any
others, to purchase from the Company such amounts as may be agreed upon and upon
the terms set forth herein, the Firm Shares or Option Shares, as the case may
be, which the defaulting Underwriter or Underwriters failed to purchase. If
during such 36 hours you, as such Representatives, shall not have procured such
other Underwriters, or any others, to purchase the Firm Shares or Option Shares,
as the case may be, agreed to be purchased by the defaulting Underwriter or
Underwriters, then (a) if the aggregate number of shares with respect to which
such default shall 


                                      -21-


<PAGE>   22
occur does not exceed 10% of the Firm Shares or Option Shares, as the case may
be, covered hereby, the other Underwriters shall be obligated, severally, in
proportion to the respective numbers of Firm Shares or Option Shares, as the
case may be, which they are obligated to purchase hereunder, to purchase the
Firm Shares or Option Shares, as the case may be, which such defaulting
Underwriter or Underwriters failed to purchase or (b) if the aggregate number of
shares of Firm Shares or Option Shares, as the case may be, with respect to
which such default shall occur exceeds 10% of the Firm Shares or Option Shares,
as the case may be, covered hereby, the Company or you as the Representatives of
the Underwriters will have the right, by written notice given within the next
36-hour period to the parties to this Agreement, to terminate this Agreement
without liability on the part of the non-defaulting Underwriters or of the
Company except to the extent provided in Section 8 hereof. In the event of a
default by any Underwriter or Underwriters, as set forth in this Section 9, the
Closing Date or Option Closing Date, as the case may be, may be postponed for
such period, not exceeding seven days, as you, as Representatives, may determine
in order that the required changes in the Registration Statement or in the
Prospectus or in any other documents or arrangements may be effected. The term
"Underwriter" includes any person substituted for a defaulting Underwriter. Any
action taken under this Section 9 shall not relieve any defaulting Underwriter
from liability in respect of any default of such Underwriter under this
Agreement.

10.     NOTICES.

        All communications hereunder shall be in writing and, except as

adverse change in or affecting the condition, financial or otherwise, of the

whether or not arising in the ordinary course of business; (ii) any outbreak or
escalation of hostilities or declaration of war or national emergency or other
national or international calamity or crisis or change in economic or political

calamity, crisis or change on the financial markets of the United States would,
in your reasonable judgment, make it impracticable to market the Shares or to

been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange or the NASD; (iv) the

rating of the Company's debt securities by any "nationally recognized
statistical rating organization" (as defined for purposes of Rule 436(g) under
the Exchange Act); or (vii) the taking of any action by any governmental body or
agency in respect of its monetary or fiscal affairs which in your reasonable
opinion has a material adverse effect on the securities markets in the United
States; or

        (c)  as provided in Sections 6 and 9 of this Agreement.

12.     SUCCESSORS.

        This Agreement has been and is made solely for the benefit of the
Underwriters and the Company and their respective successors, executors,
administrators, heirs and assigns, and the officers, directors and controlling
persons referred to herein, and no other person will have any right or
obligation hereunder. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign merely because of such purchase.

Waste Connections, Inc.
2260 Douglas Blvd., Suite 280
Roseville, California 95661


Ladies and Gentlemen:

          We have acted as counsel for Waste Connections, Inc. (the "Company")
in connection with its Registration Statement on Form S-1 (File No. 333-48029)
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended, relating to up to 2,300,000 shares of the Company's Common
Stock, $0.01 par value, to be sold by the Company.  We are of the opinion that
the shares being so registered for sale have been duly authorized and, when
sold and delivered as contemplated in such Registration Statement, will be
validly issued, fully paid and nonassessable.

          We hereby consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to such Registration Statement.

                                             Very truly yours,

                                             SHARTSIS, FRIESE & GINSBURG LLP

                            STOCK PURCHASE AGREEMENT


         STOCK PURCHASE AGREEMENT, dated as of May 8, 1998, is entered into by
and among Waste Connections, Inc., a Delaware corporation ("WCI"), Sunshine
Sanitation, Incorporated, a South Dakota corporation (the "CORPORATION"), and
Robert E. Ewing and Sherry D. Ewing (collectively, the "SHAREHOLDER").

         WHEREAS, the Corporation is engaged in the collection and transport of
solid waste and recyclables in the Cities of Spearfish, Lead, Belle Fourche,
Deadwood, Newell and Whitewood, South Dakota, and the unincorporated areas of
Meade County, Lawrence County and Butte County, South Dakota, and Crook County,
Wyoming and other related activities;

         WHEREAS, the Shareholder owns all of the issued and outstanding
capital stock of the Corporation (the "CORPORATION'S STOCK");

         WHEREAS, WCI wishes to acquire from the Shareholder all of the
Corporation's Stock;

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, representations, warranties, provisions and covenants herein
contained, the parties hereto, each intending to be bound hereby, agree as
follows:

1.       PURCHASE OF CORPORATION'S STOCK

         1.1     SHARES TO BE PURCHASED.  At the Closing (as defined in Section
2), the Shareholder shall sell and deliver to WCI all of the issued and
outstanding shares of the Corporation's Stock, being the number of shares of
the Corporation set forth on Schedule 3.2 opposite the Shareholder's name.  At
the Closing, WCI shall purchase the Corporation's Stock and in exchange
therefor shall deliver to the Shareholder at the Closing or thereafter as
provided by this Agreement the purchase price described in Section 1.2 (the
"PURCHASE PRICE").

         1.2     PURCHASE PRICE.  The Purchase Price is composed of the
following:

                 (a)      One million twenty-nine thousand dollars ($1,029,000)
         (i) minus the Closing Date Debt (as defined in Section 3.22(a)), and
         (ii) plus or minus, as the case may be, the amount by which the
         Closing Date Current Assets (as defined in Section 3.22(b)) are
         greater or less than the Closing Date Current Liabilities (as defined
         in Section 3.22(b)).  The $1,029,000 minus the Closing Date Debt shall
         be payable to the Shareholder at Closing in cash by wire transfer or
         check payable in clearinghouse funds.  Within 120 days after the
         Closing Date, WCI shall perform all necessary calculations,
         adjustments and other acts necessary to convert the Corporation from a
         cash to accrual basis of financial reporting, and then, based on such
         accrual method, WCI shall determine the actual Closing Date Debt.  If
         the difference between the actual amount and the





                                       1
<PAGE>   3

         estimated amount provided at the Closing Date of Closing Date Debt
         results in an increase in the amount that should have been paid at the
         Closing over the amount that was so paid, WCI shall promptly pay such
         amount to the Shareholder; if the result is a decrease in the amount
         that should have been paid at the Closing from the amount that was so
         paid, the Shareholder shall promptly pay such amount to WCI.  In
         addition, within 120 days after the Closing Date, WCI shall determine
         the actual Closing Date Current Assets and Closing Date Current
         Liabilities.  If the Closing Date Current Assets are greater than the
         Closing Date Current Liabilities, WCI shall promptly pay the
         difference between the two amounts to the Shareholder; if the Closing
         Date Current Liabilities are greater than the Closing Date Current
         Assets, the Shareholder shall promptly the difference between the two
         amounts to WCI;

                 (b)      At the Closing, WCI shall deliver to the Shareholder
         a Promissory Note (the "NOTE") in the aggregate principal amount of
         two hundred thousand dollars ($200,000), which Note shall be payable
         in five equal annual installments of forty thousand dollars ($40,000)
         each.  These annual installments shall be paid on the first, second,
         third, fourth and fifth anniversaries of the Closing Date.  The Note
         shall be non-interest bearing and shall be secured by a lien on all of
         the assets of the Corporation; and

                 (c)      If the Shareholder owes the Corporation money
         ("SHAREHOLDER DEBT") and the Corporation owes the Shareholder money
         ("CORPORATION DEBT"), the amount by which the Shareholder Debt exceeds
         the Corporation Debt will be deducted from the Purchase Price payable
         to that Shareholder or the amount by which the Corporation Debt
         exceeds the Shareholder Debt will be added to the Purchase Price
         payable to that Shareholder and the remaining Corporation's Debt and
         Shareholder Debt shall be cancelled.

         1.3     ALLOCATION OF THE PURCHASE PRICE.  Ten thousand dollars
($10,000) of the Purchase Price shall be allocated to the covenant not to
compete as described in Section 8.1(a) hereof, and the balance of the Purchase
Price shall be allocated to the Corporation's Stock.

         1.4     EXCLUDED ASSETS.  The Assets of the Corporation listed on

the Excluded Assets.

person.

         3.3     ALL STOCK BEING ACQUIRED.  The Corporation's Stock being
acquired by WCI hereunder constitutes all of the outstanding capital stock of

Agreement by the Corporation and the consummation of the transactions
contemplated hereby by the Corporation have been duly authorized by its Board
of Directors.  This Agreement has been duly and validly executed and delivered
by the Corporation and the Shareholder and, subject to the due authorization,
execution and delivery by WCI, constitutes the legal, valid and binding
obligation of the Corporation and the Shareholder enforceable against each of
them in accordance with its terms.

                 (a)      Schedule 3.17(a) is a complete list as of the Closing
Date, and includes complete copies (or, in the case of oral arrangements,
descriptions), of all employee benefit plans and agreements (written or oral)
currently maintained or contributed to by the Corporation, including employment
agreements and any other agreements containing "golden parachute" provisions,
retirement plans, welfare benefit plans and deferred compensation agreements,
together with copies of such plans, agreements and any trusts related thereto,
and classifications of employees covered thereby as of the Closing Date.
Except for the employee benefit plans described on Schedule 3.17(a), the
Corporation has no other pension, retirement, welfare, profit sharing, deferred
compensation, stock option, employee stock purchase or other employee benefit
plans or arrangements with any party.  Except as disclosed on Schedule 3.17(a),
all employee benefit plans listed on Schedule 3.17(a) are fully funded and in
substantial compliance with all applicable federal, state and local statutes,
ordinances and regulations.  All such plans that are intended to qualify under
Section 401(a) of the Internal Revenue Code have been determined by the
Internal Revenue Service to be so qualified, and copies of such determination
letters are included as part of Schedule 3.17(a).  Except as disclosed on
Schedule 3.17(a), all reports and other documents required to be filed with any
governmental agency or distributed to plan participants or beneficiaries
(including, but not limited to, actuarial reports, audits or tax returns) have
been timely filed or distributed, and copies thereof are included as part of
Schedule 3.17(a).  All employee benefit plans listed on such Schedule have been
operated in accordance with the terms and provisions of the plan documents and
all related documents and policies.  The Corporation has not incurred any
liability for excise tax or penalty due to the Internal Revenue Service or U.S.
Department of Labor nor any liability to the Pension Benefit Guaranty
Corporation for any employee benefit plan, nor has the Corporation, nor
party-in-interest or disqualified person, engaged in any transaction or other
activity which would give rise to such





                                       10
<PAGE>   12
liability.  The Corporation has not participated in or made contributions to
any "multi-employer plan" as defined in the Employee Retirement Income Security
Act of 1974 ("ERISA"), nor would the Corporation or any affiliate be subject to
any withdrawal liability with respect to such a plan if any such employer
withdrew from such a plan immediately prior to the Closing Date.  No employee
pension benefit plan is under funded on a termination basis as of the date of
this Agreement.

                 (b)      Schedule 3.17(b) is a complete list, as of the
Closing Date, and includes complete copies of all union contracts and
agreements between the Corporation and any collective bargaining group.  The
Corporation is in compliance in all material respects with all applicable
federal and state laws respecting employment and employment practices, terms
and conditions of employment, wages and hours, and nondiscrimination in
employment, and is not engaged in any unfair labor practice.  There is no
charge pending or, to the Corporation's or the Shareholder's knowledge,
threatened, against the Corporation before any court or agency and alleging
unlawful discrimination in employment practices and there is no charge of or
proceeding with regard to any unfair labor practice against it pending before
the National Labor Relations Board.  There is no labor strike, dispute, slow
down or stoppage as of the Closing Date, existing or threatened against the
Corporation; no union organizational activity exists respecting employees of
the Corporation not currently subject to a collective bargaining agreement; the
union contracts or other agreements delivered as part of Schedule 3.17(b)
constitute all agreements with the unions or other collective bargaining
groups, and there are no other arrangements or established practices relating
to the employees covered by any collective bargaining agreement; and Schedule
3.17(b) contains as of the date it is delivered a list of all arbitration or
grievance proceedings that have occurred since the Balance Sheet Date.  No one
has petitioned within the last five years, and no one is now petitioning, for
union representation of any employees of the Corporation.  The Corporation has
not experienced any labor strike, slow-down, work stoppage, labor difficulty or
other job action during the last five years.

                 (c)      No payment made to any employee, officer, director or
independent contractor of the Corporation (the "RECIPIENT") pursuant to any
employment contract, severance agreement or other arrangement (the "Golden
Parachute Payment") will be nondeductible by the Corporation because of the
application of Sections 280G and 4999 of the Code to the Golden Parachute
Payment, nor will the Corporation be required to compensate any Recipient
because of the imposition of an excise tax (including any interest or penalties
related thereto) on the Recipient by reason of Sections 280G and 4999 of the
Code.

         3.18    TAXES.

                 (a)      The Corporation has timely filed all requisite
federal, state, local and other tax and information returns due for all fiscal

extensions of any statute of limitations or claims against the Corporation
relating to federal, state, local or other taxes (including penalties and
interest) for any period or periods prior to and including the

Closing Date and no notice of any claim for taxes has been received.  Copies of
(i) any tax examinations, (ii) extensions of statutory limitations and (iii)
the federal income, and state franchise, income and sales tax returns of the
Corporation for its last three fiscal years are attached as part of Schedule
3.18.  Copies of all other federal, state, local and other tax and information
returns for all prior years of the Corporation's existence have been made
available to WCI and are among the records of the Corporation which will accrue
to WCI at the Closing.  The Corporation has not been contacted by any federal,
state or local taxing authority regarding a prospective examination.

                 (b)      Except as set forth on Schedule 3.18 (which schedule
also includes the amount due with respect to the Corporation) the Corporation
has duly paid all taxes and other related charges required to be paid prior to
the Closing Date.

                 (c)      The Corporation has withheld all required amounts
from its employees for all pay periods in full and complete compliance with the
withholding provisions of applicable federal, state and local laws.  All
required federal, state and local and other returns with respect to income tax
withholding, social security, and unemployment taxes have been duly filed by
the Corporation for all periods for which returns are due, and the amounts
shown on all such returns to be due and payable have been paid in full.

         3.19    COPIES COMPLETE; REQUIRED CONSENTS.  Except as disclosed on
Schedule 3.19, the certified copies of the Articles of Incorporation and Bylaws

leases, instruments, agreements, licenses, permits, certificates or other
documents that have been delivered to WCI in connection with the transactions
contemplated hereby are complete and accurate as of the Closing Date and are
true and correct copies of the originals thereof.  Except as specifically
disclosed on Schedule 3.19, the rights and benefits of the Corporation will not
be adversely affected by the transactions contemplated hereby, and the
execution of this Agreement and the performance of the obligations hereunder
will not violate or result in a breach or constitute a default under any of the
terms or provisions thereof.  None of such leases, instruments, agreements,
licenses, permits, site assessments, certificates or other documents requires
notice to, or consent or approval of, any governmental agency or other third
party to any of the transactions contemplated hereby, except the Required
Governmental Consents, such consents and approvals as are listed on Schedule
3.19; all of which will have been given or obtained prior to the Closing.

derived from billings to its customers for each of the twelve months preceding
the Closing Date.  Except as set forth on Schedule 3.20, the Corporation and
the Shareholder have no knowledge of any reason why the Corporation's average
monthly revenues derived from billings to its customers after the Closing Date
should not continue at approximately the same rate as before the Closing Date.

         3.21    NO CHANGE WITH RESPECT TO THE CORPORATION.  Except as set
forth on Schedule 3.21, since the Balance Sheet Date, the business of the
corporation has been conducted only in the ordinary course and there has been
no change in the condition (financial or otherwise) of the assets, liabilities
or operations of the Corporation other than changes in the ordinary course of
business, none of which either singly or in the aggregate has been materially
adverse.  Specifically, and without limiting the generality of the foregoing,

                 DATE CURRENT LIABILITIES.

                 (a)      Schedule 3.22(a) is an estimate based on the
Corporation's balance sheet for the period ending on the Balance Sheet Date of
(i) the amount of the aggregate debt (excluding trade payables) of the
Corporation outstanding on the Closing Date required to be repaid by WCI at or
immediately after the Closing Date and all prepayment penalties incurred or to
be incurred by WCI or the Corporation in connection with the repayment of any
such debt, (ii) the amount of the aggregate debt (excluding trade payables) of
the Corporation outstanding on the Closing Date which will remain outstanding
obligations of the Corporation after the Closing Date, and all prepayment
penalties applicable to such debt if repaid prior to maturity, including in
each case all interest accrued through and including the Closing Date, (iii)
the aggregate amount of the present value, discounted at the lease rate factor,
if known, inherent in the lease or, if the lease rate factor is not known, at
the rate charged to the Corporation by a third party lender in connection with
its most recent borrowing to finance equipment, of all lease obligations of the
Corporation that are not capitalized lease obligations and (iv) the aggregate
amount of the present value of all capitalized lease obligations (determined in
accordance with generally accepted accounting principles) of the Corporation
(the "CLOSING DATE DEBT").  Schedule 3.22(a) includes wire transfer

<PAGE>   16
(including any reserve for unpaid taxes and excluding the current portion of
long-term debt to the extent such current portion is included in Closing Date
Debt) and trade payables of the Corporation (including billed trade payables
and trade payables incurred but not yet billed) as of the Closing Date (the

prepaid expenses the benefit of which survives the Closing Date and the billed
and unbilled accounts receivable of the Corporation earned prior to the Closing
Date, and collectible on or after the Closing Date (the "CLOSING DATE CURRENT

arriving at the Closing Date Current Assets, accounts receivable owed to the
Corporation that are outstanding sixty (60) days or less prior to the Closing
Date are valued at one hundred percent (100%) of their amount, accounts
receivable outstanding sixty-one (61) to ninety (90) days prior to the Closing

         Corporation.  There are no pending and, to the Corporation's and
         Shareholder's knowledge, no threatened actions or proceedings from any
         governmental agency or any other entity involving remediation of any
         condition of the Corporate Property, including, without limitation,

         3.26    UNDERGROUND STORAGE TANKS.  Except as set forth on Schedule
3.26, no underground storage tanks containing petroleum products or wastes or
other hazardous substances regulated by 40 CFR 280 or Environmental Laws are

                 (e)      other material records with regard to the UST,
         including, without limitation, repair records, financial assurance
         compliance records and records of ownership; and

                 (f)      to the extent not otherwise set forth pursuant to the
         above, a summary description of instances, past or present, in which,
         to the Corporation's, or the Shareholder's knowledge, the UST failed
         to meet applicable standards and regulations for tightness or
         otherwise and the extent of such failure, and any other operational or
         environmental problems with regard to the UST, including, without
         limitation, spills, including spills in connection with delivery of
         materials to the UST, releases from the UST and soil contamination.

and copyrights owned by the





                                       17
<PAGE>   19

Corporation or which it is licensed to use (other than licenses to use software
for personal computer operating systems that were provided when the computer
was purchased and licenses to use software for personal computers that are
granted to retail purchasers of such software).  No patents, trade secrets,
know-how, intellectual property, trademarks, trade names, assumed names,
copyrights, or designations used by the Corporation in its business infringe on
any patents, trademarks, or copyrights, or any other rights of any person.
Neither the Corporation nor the Shareholder knows or has any reason to believe
that there are any claims of third parties to the use of any such names or any
similar name, or knows of or has any reason to believe that there exists any
basis for any such claim or claims.  WCI gives its consent to the Shareholder
to form a corporation by the name of Sunshine, Inc.

         3.28    ASSETS, ETC., NECESSARY TO BUSINESS.  The Corporation owns or

3.14(a) and 3.19, is a party to all Collection Franchises and Governmental
Permits and other agreements necessary to permit it to carry on its business as
presently conducted.  All of said Collection Franchises and Governmental
Permits and agreements have been duly obtained and, except as disclosed on
Schedules 3.5, 3.8-Part II, 3.10(a), 3.10(c) 3.14(a) and 3.19, are in full
force and effect and there are no proceedings pending or threatened which may
result in the revocation, cancellation, suspension or adverse modification of
any of the same.  Neither the Corporation nor the Shareholder has any knowledge
of any reason why all such Collection Franchises and Governmental Permits and
agreements will not remain in effect after consummation of the transactions
contemplated hereby.

         3.29    CONDEMNATION.  No Corporate Property owned or leased by the
Corporation is the subject of, or would be affected by, any pending
condemnation or eminent domain proceedings, and, to the knowledge of the
Corporation and the Shareholder, no such proceedings are threatened.

         3.30    SUPPLIERS AND CUSTOMERS.  The relations between the
Corporation and its customers are good.  Neither the Corporation nor the
Shareholder has knowledge of any fact (other than general economic and industry
conditions) which indicates that any of the suppliers supplying products,
components, materials or providing use of, or access to, landfills or disposal

such election; provided, however, that such election shall be made no later
than the due date for such election.  If such election is made by WCI:

                 (a)      WCI shall be authorized to complete Form 8023-A;

         338(h)(10) of the Internal Revenue Code of 1986, as amended, WCI shall
         reimburse the Shareholders and the Corporation for any additional
         taxes, penalties, interest and costs of preparation of amended income
         tax returns incurred due to such election resulting from the recapture
         of depreciation previously taken on various assets of the Corporation
         at ordinary income instead of capital gain rates.  Such reimbursement
         shall be in a sum computed by a simultaneous equation computing the
         additional tax owed by stockholders, as well as the tax on the payment
         of that sum.

         6.8     RESERVED.

         6.9     TITLE INSURANCE.  The Shareholder shall arrange for an
irrevocable commitment from a title insurance company reasonably acceptable to
WCI to issue, within three business days after the Closing Date, a CLTA Owner's
Policy of title insurance for the Corporate Property, in an amount as shall be
reasonably agreed upon by the Shareholder and WCI, insuring fee simple title to
the Corporate Property in the Corporation, subject only to current real
property taxes and assessments, standard printed conditions and exceptions, and
such title exceptions as shall have been accepted in writing by WCI, and
containing such endorsements as WCI may reasonably require.  The cost of such
title insurance shall be paid one-half by the Shareholder and one-half by WCI.

         6.10    GENERAL RELEASE BY SHAREHOLDER.  The Shareholder hereby fully
releases and discharges the Corporation and its directors, officers, agents and
employees from all rights, claims and actions, known or unknown, of any kind
whatsoever, which the Shareholder now has or may hereafter have against the
Corporation and its directors, officers, agents and employees, arising out of
or relating to events arising prior to or on the Closing Date, except (a) as
may be described in written contracts disclosed in Schedule 6.10 and expressly
described and specifically excepted from this release in Schedule 6.10, (b)
compensation as an employee of the Corporation for current periods expressly
described and excepted from such release on schedule 6.10, and (c) for the
obligations of the Corporation arising after the Closing Date under this
Agreement.





                                       24
<PAGE>   26

Specifically, but not by way of limitation, the Shareholder waives any right of
indemnification, contribution or other recourse against the Corporation which
he now has or may hereafter have against the Corporation with respect to
representations, warranties or covenants made in this Agreement by the
Corporation.

                 The Shareholder hereby waives and relinquishes all rights and
benefits afforded by South Dakota Codified Laws ("SDCL") 20-7- 11, which states
as follows:

                 "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS TO WHICH THE
                 CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE
                 TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
                 MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

The Shareholder understands and acknowledges the significance and consequence
of this waiver of SDCL 20-7-11 and nevertheless elects to, and does, release
those claims described in this Section 6.10, known or unknown, that he may have
now or in the future arising out of or relating to any event arising on or
prior to the date of this Agreement, except to the extent there exists
insurance coverage.

7.       INDEMNIFICATION

         7.1     INDEMNITY BY THE SHAREHOLDER.  The Shareholder, subject to the
limitations set forth in Section 7.2, covenants and agrees that he and she will
indemnify and hold harmless WCI, the Corporation and their respective
directors, officers and agents and their respective successors and assigns

Agreement, against any and all losses, damages, assessments, fines, penalties,
adjustments, liabilities, claims, deficiencies, costs, expenses (including

"Environmental Site Losses" (as such term is hereinafter defined) identified by
a WCI Indemnitee in a Claims Notice (as defined in Section 7.4(a)), or asserted

that in either case any such Claims Notice shall be given or the litigation

contingencies (all, the "7.1 INDEMNITY EVENTS"):

                 (a)      Any misrepresentation, breach of warranty, or
         nonfulfillment of any agreement or covenant on the part of the

         or any misrepresentation in or omission from any Exhibit, Schedule,
         list, certificate, or other instrument furnished or to be furnished to
         WCI pursuant to the terms of this Agreement, regardless of whether, in
         the case of a breach of a representation or a warranty, WCI relied on
         the truth of such representation or warranty or had any knowledge of
         any breach thereof.

                 (b)      The design, development, construction or operation
         of any Facility or any





                                       25
<PAGE>   27

         other "Environmental Site" as hereinafter defined, or the installation
         or operation of a UST during any period on or prior to the Closing
         Date, in excess of the amount of liability with respect thereto, if
         any, set forth on Part II of Schedule 3.8.  As used in this Agreement,
         "ENVIRONMENTAL SITE" shall mean any Facility, any UST and any other
         waste storage, processing, treatment or disposal facility, and any
         other business site or any other real property owned, leased,
         controlled or operated by the Corporation or by any predecessor
         thereof on or prior to the Closing Date.  As used in this Agreement,
         "ENVIRONMENTAL SITE LOSSES" shall mean any and all losses, damages
         (including exemplary damages and penalties), liabilities, claims,
         deficiencies, costs, expenses, and expenditures (including, without
         limitation, expenses in connection with site evaluations, risk
         assessments and feasibility studies) arising out of or required by an
         interim or final judicial or administrative decree, judgment,

         cease and desist order, abatement order, compliance order, consent
         order, clean-up order, exhumation order, reclamation order or any
         other remedial action that is required to be undertaken under federal,
         state or local law in respect of operating activities on or affecting
         any Facility, any UST or any other Environmental Site, including, but
         not limited to (x) any actual or alleged violation of any law or
         regulation respecting the protection of the environment, including,
         but not limited to, RCRA and CERCLA or any other law or regulation
         respecting the protection of the air, water and land and (y) any
         remedies or violations, whether by a private or public action, alleged
         or sought to be assessed as a consequence, directly or indirectly, of
         any "Release" (as defined below) of pollutants (including odors) or
         Hazardous Substances from any Facility, any UST or any other
         Environmental Site resulting from activities thereat, whether such
         Release is into the air, water (including groundwater) or land and
         whether such Release arose before, during or after the Closing Date.

         pumping, pouring, emitting, emptying, discharging, injecting,
         escaping, leaching, dumping or disposing into the ambient environment.
         Notwithstanding anything in this paragraph to the contrary, it is

         Hazardous Substances contained in household waste lawfully disposed of
         in a landfill during the time the Corporation owned and/or operated
         such landfill does not constitute an Environmental Site Loss.

                 (d)      All actions, suits, proceedings, demands,
         assessments, adjustments, costs and expenses (including specifically,
         but without limitation, reasonable attorneys' fees and expenses of
         investigation) incident to any of the foregoing.

         adjusted pursuant to Section 1.2(a) hereof) if the Indemnity Event
         occurs during the time period from the second anniversary of the
         Closing Date to the third anniversary of the Closing Date.

                 (c)      WCI shall use reasonable efforts to pursue any
insurance coverage it may have with respect to any matter resulting in a 7.1
Indemnity Event and shall apply any insurance recoveries it receives in
connection with any 7.1 Indemnity Event towards its recovery from the
Shareholder for such 7.1 Indemnity Event.  Nothing herein shall require WCI
from pursuing any such insurance coverage prior to pursuing any claim against
the Shareholder.

         7.3     INDEMNITY BY WCI.  WCI, subject to the limitations set forth
in Section 7.4, covenants and agrees that it will indemnify and hold harmless
the Shareholder and their respective successors and assigns (collectively the
"SHAREHOLDER INDEMNITEES"), from and after the date of this Agreement, against
any and all losses, damages, assessments, fines, penalties, adjustments,
liabilities, claims, deficiencies, costs, expenses (including specifically, but
without limitation, reasonable attorneys' fees and expenses of investigation),
expenditures, including, without limitation, any Environmental Site Losses
identified by a Shareholder Indemnitee in a Claims Notice, or asserted by a
Shareholder Indemnitee in litigation commenced against WCI provided that in
either case any such Claims Notice shall be given or the litigation commenced





                                       27
<PAGE>   29
prior to the expiration of the applicable statute of limitations (irrespective
of the date of discovery), with respect to each of the following contingencies
(all, the "7.3 INDEMNITY EVENTS"):

                 (a)      Any misrepresentation, breach of warranty, or
         nonfulfillment of any agreement or covenant on the part of WCI
         pursuant to the terms of this Agreement or any misrepresentation in or
         omission from any Exhibit, Schedule, list, certificate, or other
         instrument furnished or to be furnished to the Shareholder pursuant to
         the terms of this Agreement, regardless of whether, in the case of a
         breach of a representation or a warranty, the Shareholder relied on
         the truth of such representation or warranty or had any knowledge of
         any breach thereof.

                 (b)      The design, development, construction or operation of
         any Facility or any other Environmental Site, or the installation or
         operation of a UST during any period after the Closing Date, in excess
         of the amount of liability with respect thereto, if any, set forth on
         Part II of Schedule 3.8; provided, however, that WCI shall have no
         obligation to indemnify any Shareholder Indemnitee under this section
         7.3 if a 7.3 Indemnity Event is caused in whole or in part by a 7.1
         Indemnity Event.

                 (c)      All actions, suits, proceedings, demands,
         assessments, adjustments, costs and expenses (including specifically,
         but without limitation, reasonable attorneys' fees and expenses of
         investigation) incident to any of the foregoing.

         7.4     LIMITATIONS ON WCI'S INDEMNITIES.

                 (a)      Subject to the provisions of 7.4(b) hereof, the
obligations of WCI to indemnify the Shareholder Indemnitees as provided in
Section 7.3 shall be equal to the amount by which the cumulative amount of all
such liabilities, claims, damages deficiencies, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses, expenditures and
Environmental Site Losses with respect to any or all 7.1 Indemnity Events
exceed the General Deductible Amount.

                 (b)      The maximum amount which the Shareholder can recover
as a result of one or more 7.3 Indemnity Events shall not exceed:

                          (i)     eighty percent (80%) of the Purchase Price
         (as adjusted pursuant to Section 1.2(a) hereof) if the 7.3 Indemnity
         Event occurs during the time period from the Closing Date to, and
         including, the first anniversary of the Closing Date;

                          (ii)    seventy percent (70%) of the Purchase Price
         (as adjusted pursuant to Section 1.2(a) hereof) if the 7.3 Indemnity
         Event occurs during the time period from the first anniversary of the
         Closing Date to, and including, the second anniversary of the Closing
         Date; and





                                       28
<PAGE>   30
                          (iii)   sixty-five percent (65%) of the Purchase
         Price (as adjusted pursuant to Section 1.2(a) hereof) if the Indemnity
         Event occurs during the time period from the second anniversary of the
         Closing Date to the third anniversary of the Closing Date.

         7.5     NOTICE OF INDEMNITY CLAIM.

                 (a)      In the event that any claim ("CLAIM") is hereafter
asserted against or arises with respect to any WCI or Shareholder Indemnitee
(as applicable, an "Indemnitee") as to which such Indemnitee may be entitled to
indemnification hereunder, the Indemnitee shall notify the Shareholder (as
applicable collectively, the "INDEMNIFYING PARTY") in writing thereof (the
"CLAIMS NOTICE") within 20 days after (i) receipt of written notice of
commencement of any third party litigation against such Indemnitee, (ii)
receipt by such Indemnitee of written notice of any third party claim pursuant
to an invoice, notice of claim or assessment, against such Indemnitee, or (iii)
such Indemnitee becomes aware of the existence of any other event in respect of
which indemnification may be sought from the Indemnifying Party (including,
without limitation, any inaccuracy of any representation or warranty or breach
of any covenant).  The Claims Notice shall describe the Claim and the specific
facts and circumstances in reasonable detail, and shall indicate the amount, if
known, or an estimate, if possible, of the losses that have been or may be
incurred or suffered by the Indemnitee.

                 (b)      The Indemnifying Party may elect to defend any Claim
for money damages where the cumulative total of all Claims (including such
Claims) do not exceed the limit set forth in Section 7.2 at the time the Claim
is made, by the Indemnifying Party's own counsel; provided, however, the
Indemnifying Party may assume and undertake the defense of such a third party
Claim only upon written agreement by the Indemnifying Party that the
Indemnifying Party is obligated to fully indemnify the Indemnitee with respect
to such action.  The Indemnitee may participate, at the Indemnitee's own
expense, in the defense of any Claim assumed by the Indemnifying Party.
Without the written approval of the Indemnitee, which approval shall not be
unreasonably withheld, the Indemnifying Party shall not agree to any compromise
of a Claim defended by the Indemnifying Party.

                 (c)      If, within thirty (30) days of the Indemnifying
Party's receipt of a Claims Notice, the Indemnifying Party shall not have
provided the written agreement required by Section 7.3(b) and elected to defend
the Claim, the Indemnitee shall have the right to assume control of the defense
and/or compromise of such Claim, and the costs and expenses of such defense,
including reasonable attorneys' fees, shall be added to the Claim.  The
Indemnifying Party shall promptly, and in any event within thirty (30) days
after demand therefor, reimburse the Indemnitee for the costs of defending the
Claim, including attorneys' fees and expenses.

                 (d)      The party assuming the defense of any Claim shall
keep the other party reasonably informed at all times of the progress and
development of its or his defense of and compromise efforts with respect to
such Claim and shall furnish the other party with copies of all relevant
pleadings, correspondence and other papers.  In addition, the parties to this
Agreement





                                       29
<PAGE>   31
shall cooperate with each other and make available to each other and their
representatives all available relevant records or other materials required by
them for their use in defending, compromising or contesting any Claim.  The
failure to timely deliver a Claims Notice or otherwise notify the Indemnifying
Party of the commencement of such actions in accordance with this Section 7.3
shall not relieve the Indemnifying Party from the obligation to indemnify
hereunder but only to the extent that the Indemnifying Party establishes by
competent evidence that it has been prejudiced thereby.

                 (e)      In the event both the Indemnitee and the Indemnifying
Party are named as defendants in an action or proceeding initiated by a third
party, they shall both be represented by the same counsel (on whom they shall
agree), unless such counsel the Indemnitee, or the Indemnifying Party shall
determine that such counsel has a conflict of interest in representing both the
Indemnitee and the Indemnifying Party in the same action or proceeding and the
Indemnitee and the Indemnifying Party do not waive such conflict to the
satisfaction of such counsel.

         7.6     SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  The
representations and warranties of the parties contained in this Agreement and
in any certificate, Exhibit or Schedule delivered pursuant hereto, or in any
other writing delivered pursuant to the provisions of this Agreement (the
"REPRESENTATIONS AND WARRANTIES") and the liability of the party making such
Representations and Warranties for breaches thereof shall survive the
consummation of the transactions contemplated hereby.  The parties hereto in
executing and delivering and in carrying out the provisions of this Agreement
are relying solely on the representations, warranties, Schedules, Exhibits,
agreements and covenants contained in this Agreement, or in any writing or
document delivered pursuant to the provisions of this Agreement, and not upon
any representation, warranty, agreement, promise or information, written or
oral, made by any persons other than as specifically set forth herein or
therein, including WCI's reliance on its knowledge of events pursuant to its
due diligence review of the Corporation.

         7.7     NO EXHAUSTION OF REMEDIES OR SUBROGATION; RIGHT OF SET OFF.
The Shareholder waives any right to require any WCI Indemnitee to (i) proceed
against the Corporation; (ii) proceed against any other person; or (iii) pursue
any other remedy whatsoever in the power of any WCI Indemnitee.  WCI may, but
shall not be obligated to, set off against any and all payments due the
Shareholder any amount to which any WCI Indemnitee is entitled to be
indemnified hereunder with respect to any 7.1 Indemnity Event.  Such right of
set off shall be separate and apart from any and all other rights and remedies
that the Indemnities may have against Shareholder or his successors.

8.       OTHER POST-CLOSING COVENANTS OF THE SHAREHOLDER AND WCI

         8.1     RESTRICTIVE COVENANTS.  As to the Corporation, the Shareholder

Corporation (the "BUSINESS"); (ii) the Shareholder and his Affiliates are
intimately familiar with the Business; (iii) the Business is currently

The Shareholder covenants and agrees as set forth in (a), (b) and (c) below
with respect to the Corporation:

                 (a)      NON-COMPETE.  For a period commencing on the Closing
         Date and terminating five years thereafter (the "RESTRICTED PERIOD"),
         neither the Shareholder nor any of his Affiliates shall, anywhere in
         the Cities of Spearfish, Lead, Belle Fourche, Deadwood, Newell and

         services to or for the benefit of, or assist in or facilitate the

         gift in support of, any such business in any capacity, including,
         without limitation, as a sole proprietor, partner, shareholder,
         officer, director, principal, agent, trustee or lender; provided,
         however, that the Shareholder may (x) retain all salvage rights
         currently possessed by the Corporation in connection with the
         operation of any rubble site; and (y) own, directly or indirectly,
         solely as an investment, securities of any business traded on any
         national securities exchange or NASDAQ, provided none of the
         Shareholder is a controlling person of, or a member of a group which
         controls, such business and further provided that the Shareholder does
         not, in the aggregate, directly or indirectly, own 2% or more of any
         class of securities of such business.

                 (b)      CONFIDENTIAL INFORMATION.  During the Restricted
         Period and thereafter, the Shareholder and his Affiliates shall keep
         secret and retain in strictest confidence, and shall not use for the
         benefit of themselves or others, all data and information relating to
         the Business ("CONFIDENTIAL INFORMATION"), including without
         limitation, know-how, trade secrets, customer lists, supplier lists,
         details of contracts, pricing policies, operational methods, marketing
         plans or strategies, bidding information, practices,





                                       31
<PAGE>   33

         policies or procedures, product development techniques or plans, and
         technical processes; provided, however, that the term "Confidential
         Information" shall not include information that (i) is or becomes
         generally available to the public other than as a result of disclosure
         by the Shareholder or (ii) is general knowledge in the solid waste
         handling and landfill business and not specifically related to the
         Business.

                 (c)      PROPERTY OF THE BUSINESS.  All memoranda, notes,
         lists, records and other documents or papers (and all copies thereof)
         relating to the Business, including such items stored in computer
         memories, on microfiche or by any other means, made or compiled by or
         on behalf of the Shareholder or the Corporation or made available to
         them relating to the Business, but excluding any materials (other than
         the minute books of the Corporation) maintained by any attorneys for
         the Corporation or the Shareholder prior to the Closing, are and shall
         be the property of WCI and have been delivered or will be delivered or
         made available to WCI at the Closing.  The Shareholder has the right
         on reasonable request to inspect and copy during normal business hours
         any of such property relating to the Business.

                 (d)      NON-SOLICITATION.  Without the consent of WCI, which
         may be granted or withheld by WCI in its discretion, the Shareholder
         and his Affiliates shall not solicit any employees of the Corporation
         to leave the employ of the Corporation and join the Shareholder or any
         Affiliate in any business endeavor owned or pursued by the
         Shareholder.

                 (e)      NO DISPARAGEMENT.  From and after the Closing Date,
         the Shareholder shall not, in any way or to any person or entity or
         governmental or regulatory body or agency, denigrate or derogate WCI
         or any of its subsidiaries, or any officer, director or employee, or
         any product or service or procedure of any such company whether or not
         such denigrating or derogatory statements shall be true and are based
         on acts or omissions which are learned by the Shareholder from and
         after the date hereof or on acts or omissions which occur from and
         after the date hereof, or otherwise.  A statement shall be deemed
         denigrating or derogatory to any person or entity if it adversely
         affects the regard or esteem in which such person or entity is held by
         investors, lenders or licensing, rating, or regulatory entities.
         Without limiting the generality of the foregoing, the Shareholder
         shall not, directly or indirectly in any way in respect of any such
         company or any such directors or officers, communicate with, or take
         any action which is adverse to the position of any such company with
         any person, entity or governmental or regulatory body or agency who or
         which has dealings or prospective dealings with any such company or
         jurisdiction or prospective jurisdiction over any such company.  This
         paragraph does not apply to the extent that testimony is required by
         legal process, provided that WCI has received not less than five days'
         prior written notice of such proposed testimony.

         8.2     RIGHTS AND REMEDIES UPON BREACH.  If the Shareholder or any
Affiliate breaches, or threatens to commit a breach of, any of the provisions
of Section 8.1 herein (the "RESTRICTIVE COVENANTS"), WCI shall have the
following rights and remedies, each of which





                                       32
<PAGE>   34

rights and remedies shall be independent of the others and severally
enforceable, and each of which is in addition to, and not in lieu of, any other
rights and remedies available to WCI at law or in equity:

                 (a)      SPECIFIC PERFORMANCE.  The right and remedy to have
         the Restrictive Covenants specifically enforced by any court of
         competent jurisdiction, it being agreed that any breach or threatened
         breach of the Restrictive Covenants would cause irreparable injury to
         WCI and that money damages would not provide an adequate remedy to
         WCI.  Accordingly, in addition to any other rights or remedies, WCI
         shall be entitled to injunctive relief to enforce the terms of the
         Restrictive Covenants and to restrain the Shareholder from any
         violation thereof.

                 (b)      ACCOUNTING.  The right and remedy to require the
         Shareholder to account for and pay over to WCI all compensation,
         profits, monies, accruals, increments or other benefits derived or
         received by the Shareholder as the result of any transactions
         constituting a breach of the Restrictive Covenants.

                 (c)      SEVERABILITY OF COVENANTS.  The Shareholder
         acknowledges and agrees that the Restrictive Covenants are reasonable
         and valid in geographical and temporal scope and in all other
         respects.  If any court determines that any of the Restrictive
         Covenants, or any part thereof, is invalid or unenforceable, the
         remainder of the Restrictive Covenants shall not thereby be affected
         and shall be given full effect, without regard to the invalid
         portions.

                 (d)      BLUE-PENCILING.  If any court determines that any of
         the Restrictive Covenants, or any part thereof, is unenforceable
         because of the duration or geographic scope of such provision, such
         court shall reduce the duration or scope of such provision, as the
         case may be, to the extent necessary to render it enforceable and, in
         its reduced form, such provision shall then be enforced.

                 (e)      ENFORCEABILITY IN JURISDICTION.  WCI and the
         Shareholder intend to and hereby confer jurisdiction to enforce the
         Restrictive Covenants upon the courts of any jurisdiction within the
         geographic scope of the Restrictive Covenants.  If the courts of any
         one or more of such jurisdictions hold the Restrictive Covenants
         unenforceable by reason of the breadth of such scope or otherwise, it
         is the intention of WCI and the Shareholder that such determination
         not bar or in any way affect WCI's right to the relief provided above
         in the courts of any other jurisdiction within the geographic scope of
         the Restrictive Covenants as to breaches of such covenants in such
         other respective jurisdictions, such covenants as they relate to each
         jurisdiction being, for this purpose, severable into diverse and
         independent covenants.

9.       GENERAL

         9.1     ADDITIONAL CONVEYANCES.  Following the Closing, the
Shareholder and WCI shall

however, that any such assignment shall be subject to the terms of this
Agreement and shall not relieve the assignor of its or his responsibilities
under this Agreement.

         9.3     PUBLIC ANNOUNCEMENTS.  Except as required by law, no party
shall make any public announcement or filing with respect to the transactions
provided for herein prior to the Closing Date without the prior consent of the
other parties hereto.

         9.4     COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same instrument.

         9.5     NOTICES.  All notices, requests, demands and other

                            STOCK PURCHASE AGREEMENT


         STOCK PURCHASE AGREEMENT, dated as of May 8, 1998, is entered into by
and among Waste Connections, Inc., a Delaware corporation ("WCI"), Sowers'
Sanitation, Inc., a South Dakota corporation (the "CORPORATION"), and James C.
Sowers ("CLARK") and Mildred A. Sowers (collectively, the "SHAREHOLDERS").

         WHEREAS, the Corporation is engaged in the collection and transport of
solid waste and recyclables in the Cities of Deadwood, Whitewood, Nisland and
Central City, South Dakota, the unincorporated areas of Lawrence County, South
Dakota and Butte County, South Dakota and other related activities;

         WHEREAS, the Shareholders own all of the issued and outstanding
capital stock of the Corporation (the "CORPORATION'S STOCK");

         WHEREAS, WCI wishes to acquire from the Shareholders all of the
Corporation's Stock;

         WHEREAS, concurrent with the execution of this Agreement, WCI, as
lessee, and the Shareholders, as lessor (the "LESSOR"), will enter into a Lease
(the "LEASE") of certain real estate located in Deadwood, South Dakota, used in
the Corporation's business;

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, representations, warranties, provisions and covenants herein
contained, the parties hereto, each intending to be bound hereby, agree as
follows:

1.       PURCHASE OF CORPORATION'S STOCK

         1.1     SHARES TO BE PURCHASED.  At the Closing (as defined in Section
2), the Shareholders shall sell and deliver to WCI all of the issued and
outstanding shares of the Corporation's Stock, being the number of shares of
the Corporation set forth on Schedule 3.2 opposite each Shareholder's name.  At
the Closing, WCI shall purchase the Corporation's Stock and in exchange
therefor shall deliver to the Shareholders at the Closing or thereafter as
provided by this Agreement the purchase price described in Section 1.2 (the
"PURCHASE PRICE").

         1.2     PURCHASE PRICE.  The Purchase Price is:

                 (a)      six hundred thousand dollars ($600,000), (i) minus
         the Closing Date Debt (as defined in Section 3.22(a)), and (ii) plus
         or minus, as the case may be, the amount by which the Closing Date
         Current Assets (as defined in Section 3.22(b)) are greater or less
         than the Closing Date Current Liabilities (as defined in Section
         3.22(b)).  The $600,000 minus the Closing Date Debt shall be payable
         to the Shareholders at Closing in cash by





                                       1
<PAGE>   3

         wire transfer or check payable in clearinghouse funds.  Within 120
         days after the Closing Date, WCI shall perform all necessary
         calculations, adjustments and other acts necessary to convert the
         Corporation from a cash to accrual basis of financial reporting, and
         then, based on such accrual method, WCI shall determine the actual
         Closing Date Debt.  If the difference between the actual amount and
         the estimated amount provided at the Closing Date of Closing Date Debt
         results in an increase in the amount that should have been paid at the
         Closing over the amount that was so paid, WCI shall promptly pay such
         amount to the Shareholder; if the result is a decrease in the amount
         that should have been paid at the Closing from the amount that was so
         paid, the Shareholders shall promptly pay such amount to WCI.  In
         addition, within 120 days after the Closing Date, WCI shall determine
         the actual Closing Date Current Assets and Closing Date Current
         Liabilities.  If the Closing Date Current Assets are greater than the
         Closing Date Current Liabilities, WCI shall promptly pay the
         difference between the two amounts to the Shareholder; if the Closing
         Date Current Liabilities are greater than the Closing Date Current
         Assets, the Shareholders shall promptly the difference between the two
         amounts to WCI;

                 (b)      27,272 shares (the "SHARES") of the WCI's Common
         Stock, $0.01 par value (the "WCI STOCK"), which shall be delivered by
         WCI to the Shareholders at the Closing;

                 (c)      At the Closing, WCI shall deliver to the Shareholders
         a Promissory Note (the "SHAREHOLDER NOTE") in the aggregate principal
         amount of two hundred fifty thousand dollars ($250,000), which
         Shareholder Note shall be payable in three equal annual installments
         of eighty-three thousand three hundred thirty-three dollars ($83,333)
         each.  These annual installments shall be paid on the first, second
         and third anniversaries of the Closing Date.  The Shareholder Note
         shall be non-interest bearing and shall be secured by a lien on all of
         the assets of the Corporation;

                 (d)      At the Closing, WCI shall deliver to Clark a
         Promissory Note (the "CLARK NOTE") in the aggregate principal amount
         of one hundred fifteen thousand five hundred dollars ($115,500), which
         Clark Note shall be payable in thirty-six equal monthly installments
         of three thousand two hundred eight dollars and thirty-three cents
         ($3,208.33) each.  These monthly installments shall be paid on the
         same day of each month as the date on which the Closing Date occurs;
         and

                 (e)      If a Shareholder owes the Corporation money
         ("SHAREHOLDER DEBT") and the Corporation owes a Shareholder money
         ("CORPORATION DEBT"), the amount by which the Shareholder Debt exceeds
         the Corporation Debt will be deducted from the Purchase Price payable
         to that Shareholder or the amount by which the Corporation Debt
         exceeds the Shareholder Debt will be added to the Purchase Price
         payable to that Shareholder and the remaining Corporation Debt and
         Shareholder Debt shall be cancelled.

         1.3     PRICE PROTECTION FOR SHARES OF THE WCI STOCK.  If the gross
offering price of the WCI Stock in the IPO (as defined below), before
underwriting discounts and commissions and





                                       2
<PAGE>   4
payment of expenses of the offering (the "IPO PRICE"), is less than nine
dollars ($9.00) per share, WCI will, within 15 days after the closing of the
IPO, issue to Seller a number of additional shares of the WCI Stock determined
by multiplying (x) the difference between the IPO Price and nine dollars
($9.00) and (y) 27,272 shares and dividing that product by the IPO price.  In
lieu of issuing any fractional shares, WCI shall pay cash to Seller an amount
equal to the fraction of a share that would have been delivered times the IPO
Price.  For purposes of this agreement, "IPO" means a public offering of the
WCI Stock registered under the Securities Act of 1933 (the "ACT") and sold
through underwriters pursuant to a firm commitment in the amount of at least
five million dollars at an IPO Price of at least five dollars ($5.00) per
share.  If the closing of the IPO shall not have occurred by July 31, 1998,
Seller may, at its option exercised no later than August 15, 1998, by written
notice to WCI, cause WCI to repurchase all or any portion of the WCI Stock
issued to Seller for eleven dollars ($11.00) per share, payable by wire
transfer to the account of Seller.  Promptly upon exercise of such option,
Seller and WCI shall arrange for a closing of the sale of such WCI Stock, such
closing to occur no later than August 31, 1998.

         1.4     ALLOCATION OF THE PURCHASE PRICE.  Ten thousand dollars
($10,000) of the Purchase Price shall be allocated to the covenant not to
compete as described in Section 8.1(a) hereof, and the balance of the Purchase
Price shall be allocated to the Corporation's Stock.

         1.5     EXCLUDED ASSETS.  The Assets of the Corporation listed on
Schedule 1.5 (the "EXCLUDED ASSETS") shall be distributed to the Shareholders
prior to the Closing, and WCI shall acquire no interest in or claim to any of
the Excluded Assets.

2.       CLOSING TIME AND PLACE

         Subject to the terms and conditions of this Agreement, the closing of
the transactions contemplated herein (the "CLOSING") shall take place
concurrent with the execution of this Agreement or on such date as WCI and the
Shareholders' Representative shall agree (the "CLOSING DATE").  The Closing
shall take place through an exchange of consideration and signed documents by
facsimile, to be promptly followed by an exchange of documents bearing original
signatures by overnight courier service.  At the Closing, WCI, the Corporation
and the Shareholders shall deliver to each other the documents, instruments and
other items described in Section 5 of this Agreement.

3.       REPRESENTATIONS AND WARRANTIES OF THE CORPORATION AND THE SHAREHOLDERS

         The Corporation and the Shareholders, jointly and severally, (i)
represent and warrant that each of the following representations and warranties
is true as of the Closing Date, and (ii) agree that such representations and
warranties shall survive the Closing.

         3.1     ORGANIZATION, STANDING AND QUALIFICATION.  The Corporation is
duly organized, validly existing and in good standing under the laws of the
State of South Dakota.  The





                                       3
<PAGE>   5

Corporation has full corporate power and authority to own and lease its
properties and to carry on its business as now conducted.  The Corporation is
not required to be qualified or licensed to conduct business as a foreign
corporation in any other jurisdiction.

         3.2     CAPITALIZATION.  Schedule 3.2 sets forth, as of the Closing
Date, the authorized and outstanding capital of the Corporation, the names,
addresses and social security numbers or taxpayer identification numbers of the
record and beneficial owners thereof, the number of shares so owned, the
allocation of the cash and Shares among the Shareholders as agreed to among
themselves, and wire transfer instructions for each Shareholder relating to the
bank account to which the Purchase Price should be sent.  On the Closing Date,
all of the issued and outstanding shares of the capital stock of the
Corporation are owned of record and beneficially by the Shareholders, as set
forth in Schedule 3.2, and are free and clear of all liens, security interests,
encumbrances and claims of every kind except as set forth in Schedule 3.2.
Each share of the capital stock of the Corporation is duly and validly
authorized and issued, fully paid and nonassessable, and was not issued in
violation of any preemptive rights of any past or present shareholder of the
Corporation.  No option, warrant, call, conversion right or commitment of any
kind (including any of the foregoing created in connection with any
indebtedness of the Corporation) exists which obligates the Corporation to
issue any of its authorized but unissued capital stock or other equity interest
or which obligates any Shareholder to transfer the Corporation's Stock to any
person.

         3.3     ALL STOCK BEING ACQUIRED.  The Corporation's Stock being
acquired by WCI hereunder constitutes all of the outstanding capital stock of

and to perform its, his or her obligations hereunder.  The execution and
delivery of this Agreement by the Corporation and the consummation of the
transactions contemplated hereby by the Corporation have been duly authorized
by its Board of Directors.  This Agreement has been duly and validly executed
and delivered by the Corporation and each of the Shareholders and, subject to
the due authorization, execution and delivery by WCI, constitutes the legal,
valid and binding obligation of the Corporation and each of the Shareholders
enforceable against each of them in accordance with its terms.

         3.5     NO BREACH OR DEFAULT.  Except as disclosed on Schedule 3.5,
the execution and delivery by the Corporation and the Shareholders of this
Agreement, and the consummation by the Shareholders of the transactions
contemplated hereby, will not:

                 (a)      result in the breach of any of the terms or
         conditions of, or constitute a default under, or allow for the
         acceleration or termination of, or in any manner release any party
         from any obligation under, any mortgage, lease, note, bond, indenture,
         or material contract, agreement, license or other instrument or
         obligation of any kind or nature to which the Corporation or any of
         the Shareholders is a party, or by which the Corporation or any of the
         Shareholders, or any of its or their assets, is or may be bound

         or affected; or

                 (b)      violate any law or any order, writ, injunction or
         decree of any court, administrative agency or governmental authority,
         or require the approval, consent or permission of any governmental or
         regulatory authority; or

                 (c)      violate the Articles of Incorporation or Bylaws of
         the Corporation.

         3.6     SUBSIDIARIES.  Schedule 3.6 lists as of the Closing Date any

corporation or any securities or other interest in any other business entity

         3.7     FINANCIAL STATEMENTS.  The Corporation has delivered to WCI,
as Schedule 3.7, copies of financial statements ("FINANCIAL STATEMENTS") for
its three most recent fiscal years, compiled by Lang & Spidel and unaudited
interim financial statements for the Corporation, prepared by David Pummel &
Associates, Certified Public Accountants, for the period ended January 31, 1998

                 (a)      Schedule 3.10(a) is a full and complete list, and
         includes copies, of all material permits, licenses, franchises, and
         service agreements pursuant to which the Corporation is authorized to
         collect and haul industrial, commercial and residential solid waste
         (the "COLLECTION FRANCHISES"), and of all other material permits,
         licenses, titles (including motor vehicle titles and current
         registrations), fuel permits, zoning and land use approvals and
         authorizations, including, without limitation, any conditional or
         special use approvals or zoning variances, occupancy permits, and any
         other similar documents constituting a material authorization or
         entitlement or otherwise material to the operation of the business of
         the Corporation (collectively the "GOVERNMENTAL PERMITS") owned by,
         issued to, held by or otherwise benefitting the Corporation or the
         Shareholders as of the Closing Date.  The status of the Governmental
         Permits related to the disposal areas owned or used by the
         Corporation, including, without limitation, any conditions thereto
         and, if applicable, the expiration dates thereof, are also described
         in Schedule 3.10(a).  Schedule 3.10(a) also sets forth the name of any
         governmental agency or other third party from whom the Shareholders,
         the Corporation or WCI must obtain consent (the "REQUIRED GOVERNMENTAL
         CONSENTS") in order to effect a direct or indirect transfer of the
         Collection Franchises or other Governmental Permits required as a
         result of the consummation of the transactions contemplated by this
         Agreement.  All such consents have been obtained.  Except as set forth
         on Schedule 3.10(a), all of the Collection Franchises and other
         Governmental Permits enumerated and listed on Schedule 3.10(a) are

         Governmental Permits and agreements have been duly obtained and are in
         full force and effect, and there are no proceedings pending or, to the
         knowledge of the Corporation or the Shareholders, threatened which may
         result in the revocation, cancellation, suspension or adverse
         modification of any of the same.  Neither the Corporation nor any of
         the Shareholders has any knowledge of any reason why all such
         Governmental Permits and agreements will not remain in effect after
         consummation of the transactions contemplated hereby.

                 approvals, zoning or land use requirements, rules and
                 regulations, and no Facility or the current use thereof
                 constitutes a non-conforming use or is otherwise subject to

                 reconstruction thereof.

                          (ii)     All activities and operations at each
                 Facility are being and have been conducted in compliance in

                 standards and conditions set forth in all applicable federal,

                 Facility Property.

                          (iv)     There are no circumstances, conditions or
                 reasons which are likely to be the basis for revocation or

                 licenses, consents, authorizations, zoning or land use
                 permits, variances or approvals relating to any Facility owned

         Corporation has not incurred any liability for excise tax or penalty
         due to the Internal Revenue Service or U.S. Department of Labor nor
         any liability to the Pension Benefit Guaranty Corporation for any
         employee benefit plan, nor has the Corporation, nor party-in-interest
         or disqualified person, engaged in any transaction or other activity
         which would give rise to such liability.  The Corporation has not
         participated in or made contributions to any "multi-employer plan" as
         defined in the Employee Retirement Income Security Act of 1974
         ("ERISA"), nor would the Corporation or any affiliate be subject to
         any withdrawal liability with respect to such a plan if any such
         employer withdrew from such a plan immediately prior to the Closing
         Date.  No employee pension benefit plan is under funded on a
         termination basis as of the date of this Agreement.

                 (b)      Schedule 3.17(b) is a complete list, as of the
         Closing Date, and includes complete copies of all union contracts and
         agreements between the Corporation and any collective bargaining
         group.  The Corporation is in compliance in all material respects with
         all applicable federal and state laws respecting employment and
         employment practices, terms and conditions of employment, wages and
         hours, and nondiscrimination in employment, and is not engaged in any
         unfair labor practice.  There is no charge pending or, to the
         Corporation's or the Shareholders' knowledge, threatened, against the
         Corporation before any court or agency and alleging unlawful
         discrimination in





                                       12
<PAGE>   14
         employment practices and there is no charge of or proceeding with
         regard to any unfair labor practice against it pending before the
         National Labor Relations Board.  There is no labor strike, dispute,
         slow down or stoppage as of the Closing Date, existing or threatened
         against the Corporation; no union organizational activity exists
         respecting employees of the Corporation not currently subject to a
         collective bargaining agreement; the union contracts or other
         agreements delivered as part of Schedule 3.17(b) constitute all
         agreements with the unions or other collective bargaining groups, and
         there are no other arrangements or established practices relating to
         the employees covered by any collective bargaining agreement; and
         Schedule 3.17(b) contains as of the date it is delivered a list of all
         arbitration or grievance proceedings that have occurred since the
         Balance Sheet Date.  No one has petitioned within the last five years,
         and no one is now petitioning, for union representation of any
         employees of the Corporation.  The Corporation has not experienced any
         labor strike, slow-down, work stoppage, labor difficulty or other job
         action during the last five years.

                 (c)      No payment made to any employee, officer, director or
         independent contractor of the Corporation (the "RECIPIENT") pursuant
         to any employment contract, severance agreement or other arrangement
         (the "Golden Parachute Payment") will be nondeductible by the
         Corporation because of the application of Sections 280G and 4999 of
         the Code to the Golden Parachute Payment, nor will the Corporation be
         required to compensate any Recipient because of the imposition of an
         excise tax (including any interest or penalties related thereto) on
         the Recipient by reason of Sections 280G and 4999 of the Code.

         3.18    TAXES.

                 (a)      The Corporation has timely filed all requisite
         federal, state, local and other tax and information returns due for
         all fiscal periods ended on or before the Closing Date.  All such
         returns are accurate and complete.  Except as set forth on Schedule
         3.18, there are no open years (other than those within the statute of
         limitations), examinations in progress, extensions of any statute of
         limitations or claims against the Corporation relating to federal,
         state, local or other taxes (including penalties and interest) for any
         period or periods prior to and including the Closing Date and no
         notice of any claim for taxes has been received.  Copies of (i) any
         tax examinations, (ii) extensions of statutory limitations and (iii)
         the federal income, and state franchise, income and sales tax returns
         of the Corporation for its last three fiscal years are attached as
         part of Schedule 3.18.  Copies of all other federal, state, local and
         other tax and information returns for all prior years of the
         Corporation's existence have been made available to WCI and are among
         the records of the Corporation which will accrue to WCI at the
         Closing.  The Corporation has not been contacted by any federal, state
         or local taxing authority regarding a prospective examination.

                 (b)      Except as set forth on Schedule 3.18 (which schedule
         also includes the amount due with respect to the Corporation) the
         Corporation has duly paid all taxes and





                                       13
<PAGE>   15

         other related charges required to be paid prior to the Closing Date.
         The reserves for taxes contained in the Financial Statements of the
         Corporation are adequate to cover its tax liability as of the Closing
         Date.

                 (c)      The Corporation has withheld all required amounts
         from its employees for all pay periods in full and complete compliance
         with the withholding provisions of applicable federal, state and local
         laws.  All required federal, state and local and other returns with
         respect to income tax withholding, social security, and unemployment
         taxes have been duly filed by the Corporation for all periods for
         which returns are due, and the amounts shown on all such returns to be
         due and payable have been paid in full.

         3.19    COPIES COMPLETE; REQUIRED CONSENTS.  Except as disclosed on
Schedule 3.19, the certified copies of the Articles of Incorporation and Bylaws
of the Corporation, both as amended to the Closing Date, and the copies of all
leases, instruments, agreements, licenses, permits, certificates or other
documents that have been delivered to WCI in connection with the transactions
contemplated hereby are complete and accurate as of the Closing Date and are
true and correct copies of the originals thereof.  Except as specifically
disclosed on Schedule 3.19, the rights and benefits of the Corporation will not
be adversely affected by the transactions contemplated hereby, and the
execution of this Agreement and the performance of the obligations hereunder
will not violate or result in a breach or constitute a default under any of the
terms or provisions thereof.  None of such leases, instruments, agreements,
licenses, permits, site assessments, certificates or other documents requires
notice to, or consent or approval of, any governmental agency or other third
party to any of the transactions contemplated hereby, except the Required
Governmental Consents, such consents and approvals as are listed on Schedule
3.19; all of which will have been given or obtained prior to the Closing.

         3.20    CUSTOMERS, BILLINGS, CURRENT RECEIPTS AND RECEIVABLES.
Schedule 3.20 is a current, accurate and complete list of, and includes:

                 (a)      the customers the Corporation serves on an ongoing
         basis, including name, location and current billing rate, as of the
         Closing Date;

                 (b)      an accurate and complete aging of all accounts and
         notes receivable from customers as of the last day of the month
         preceding the month in which such Schedule is delivered, showing
         amounts due in 30-day aging categories.  Except to the extent of the
         allowance for bad debts reflected on the Financial Statements or
         otherwise disclosed on Schedules 3.11 and 3.20, the Corporation's
         accounts and notes receivable are collectible in the amounts shown on
         Schedules 3.11 and 3.20; and

                 (c)      the average monthly revenues of the Corporation
         derived from billings to its customers for each of the twelve months
         preceding the Closing Date.  Except as set forth on Schedule 3.20, the
         Corporation and the Shareholders have no knowledge of any reason why
         the Corporation's average monthly revenues derived from billings to
         its customers after the Closing Date should not continue at
         approximately the same rate as





                                       14

         before the Closing Date.

         3.21    NO CHANGE WITH RESPECT TO THE CORPORATION.  Except as set
forth on Schedule 3.21, since the Balance Sheet Date, the business of the
corporation has been conducted only in the ordinary course and there has been
no change in the condition (financial or otherwise) of the assets, liabilities

business, none of which either singly or in the aggregate has been materially
adverse.  Specifically, and without limiting the generality of the foregoing,

         its properties or business;

         Affiliates, other than in the ordinary course of business;

                 (h)      any cancellation, or agreement to cancel, any

         to which it is a party;

                 (m)      any other material transaction outside the ordinary
         course of its business.

         penalties incurred or to be incurred by WCI or the Corporation in
         connection with the repayment of any such debt, (ii) the amount of the
         aggregate debt (excluding trade payables) of the Corporation
         outstanding on the Closing Date which will remain outstanding

         recent borrowing to finance equipment, of all lease obligations of the
         Corporation that are not capitalized lease obligations and (iv) the
         aggregate amount of the present value of all capitalized lease

         Schedule 3.22(a) includes wire transfer instructions for creditors

         Corporation earned prior to the Closing Date, and collectible (less an

         expressly acknowledge that in arriving at the Closing Date Current
         Assets, accounts receivable owed to the Corporation that are
         outstanding sixty (60) days or less prior to the Closing Date are

                 (d)      Except as allowed under Environmental Laws, the

         aware that the Shares have not been registered under the Act, or

         ground, among others, that no unregistered distribution or public
         offering of Shares is to be effected and the Shares are being issued
         by WCI without any public offering within the meaning of section 4(2)
         of the Act.

         require registration of any such Shares under the Act or qualification
         of any such Shares under any other securities law; or (iii) Rule 144
         is available with respect to such transaction.

                 (h)      Each of the Shareholders understands and agrees that
         each certificate or other instrument representing the Shares will bear
         a legend on the face thereof (or on the reverse thereof with a
         reference to such legend on the face thereof) which legend restricts
         the sale, transfer or other disposition of the Shares otherwise than
         in accordance with Sections 3.38(g) of this Agreement provided,
         however, that WCI shall, on the request of any of the Shareholders,
         cause such legends to be removed from the certificates or other
         instrument evidencing the Shares if such Shareholder has held such

         under the Act).

                 (i)      Each of the Shareholders understands and agrees that
         the Shares will be "restricted securities" as that term is defined in
         Rule 144 under the Act and, accordingly, that the Shares must be held
         indefinitely unless subsequently registered under the Act or an
         exemption from such registration is available.

                 (j)      The Shareholders agree to be bound with respect to
         the Shares by any "lock up" provisions to which the executive officers

         hereunder, (iv) to retain legal counsel and other professional
         services, at the expense of the Shareholders, in connection with the
         performance by the Shareholders' Representative of this Agreement, and
         (v) to do each and every act and exercise any and all rights which
         such Shareholder or Shareholders are permitted or required to do or
         exercise under this Agreement and the other agreements, documents and
         certificates executed in connection herewith.  Each of the
         Shareholders agrees that such agency and proxy are coupled with an
         interest, are therefore irrevocable without the consent of the
         Shareholders' Representative and shall survive the death, bankruptcy
         or other incapacity of any Shareholder.

                          (c)     Each of the Shareholders hereby agrees that
         any amendment or waiver under this Agreement, and any action taken on
         behalf of the Shareholders to enforce the rights of the Shareholders
         under this Agreement, and any action taken with respect to any
         adjustment or Claim (including any action taken to object to, defend,
         compromise or agree to the payment of such adjustment or Claim), shall
         be effective if approved in writing by persons who were the holders of
         a majority of the Corporation's Stock immediately prior to the
         Closing, and that each and every action so taken shall be binding and
         conclusive on every Shareholder, whether or not such Shareholder had
         notice of, or approved, such amendment or waiver.

                          (d)     Clark shall serve as the Shareholders'
         Representative until he resigns or is otherwise unable or unwilling to
         serve.  In the event that a Shareholders' Representative resigns from
         such position or is otherwise unable or unwilling to serve, the
         remaining Shareholders shall select, by the vote of the holders of a
         majority of the Corporation's Stock immediately prior to the Closing,
         a successor representative to fill such vacancy, shall provide prompt
         written notice to WCI of such change and such substituted
         representative shall then be deemed to be the Shareholders'
         Representative for all purposes of this Agreement.

         6.9     GENERAL RELEASE BY SHAREHOLDERS.  Except as may be otherwise
covered by any policy of insurance carried by the Corporation, each of the
Shareholders hereby fully releases and discharges the Corporation and its
directors, officers, agents and employees from all rights, claims and actions,
known or unknown, of any kind whatsoever, which any of such Shareholders now
has or may hereafter have against the Corporation and its directors, officers,
agents and employees, arising out of or relating to events arising prior to or
on the Closing Date, except (a) as may be described in written contracts
disclosed in Schedule 6.9 and expressly described and specifically excepted
from this release in Schedule 6.9, (b) compensation as an employee of the
Corporation for current periods expressly described and excepted from such
release on schedule 6.9, and (c) for the obligations of the Corporation arising
after the Closing Date under this Agreement.  Specifically, but not by way of
limitation, each of the Shareholders waives any right of indemnification,
contribution or other recourse against the Corporation which he now has or may
hereafter have against the Corporation with respect to representations,
warranties or covenants made in this Agreement by the Corporation.

                 Each of the Shareholders hereby waives and relinquishes all
rights and benefits afforded by Section 1542 of the California Civil Code,
which states as follows:

           "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS TO WHICH THE
         CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE
         TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
              MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

Each of the Shareholders understands and acknowledges the significance and
consequence of this waiver of Section 1542 and nevertheless elects to, and
does, release those claims described in this Section 6.9, known or unknown,
that it may have now or in the future arising out of or relating to any event
arising on or prior to the date of this Agreement.

         6.10    CONTINUING EMPLOYEES.  WCI shall maintain the same or
comparable compensation and insurance coverage for employees of the Corporation
after the Closing Date so long as those employees remain employees of the
Corporation.

7.       INDEMNIFICATION

         7.1     INDEMNITY BY THE SHAREHOLDERS.  Except as may be otherwise
covered by any policy of insurance carried by the Corporation, each of the
Shareholders, jointly and severally, subject to the limitations set forth in
Section 7.2, covenants and agrees that he or she will indemnify and hold
harmless WCI, the Corporation and their respective directors, officers and
agents and their respective successors and assigns (collectively the "WCI
INDEMNITEES"), from and after the date of this Agreement, against any and all
losses, damages, assessments, fines, penalties, adjustments, liabilities,
claims, deficiencies, costs, expenses (including specifically, but without
limitation, reasonable attorneys' fees and expenses of investigation),
expenditures, including, without limitation, any "Environmental Site Losses"
(as such term is hereinafter defined) identified by a WCI Indemnitee in a
Claims Notice (as defined in Section 7.3(a)), or





                                       29
<PAGE>   31
asserted by a WCI Indemnitee in litigation commenced against the Shareholders
provided that in either case any such Claims Notice shall be given or the
litigation commenced prior to the third anniversary of this Agreement
(irrespective of the date of discovery), with respect to each of the following
contingencies (all, the "7.1 INDEMNITY EVENTS"):

                 (a)      Any misrepresentation, breach of warranty, or
         nonfulfillment of any agreement or covenant on the part of the
         Shareholders or the Corporation pursuant to the terms of this
         Agreement or any misrepresentation in or omission from any Exhibit,
         Schedule, list, certificate, or other instrument furnished or to be
         furnished to WCI pursuant to the terms of this Agreement, regardless
         of whether, in the case of a breach of a representation or a warranty,
         WCI relied on the truth of such representation or warranty or had any
         knowledge of any breach thereof.

                 (b)      The design, development, construction or operation of
         any Facility or any other "Environmental Site" as hereinafter defined,
         or the installation or operation of a UST during any period on or
         prior to the Closing Date, in excess of the amount of liability with
         respect thereto, if any, set forth on Part II of Schedule 3.8.  As
         used in this Agreement, "ENVIRONMENTAL SITE" shall mean any Facility,
         any UST and any other waste storage, processing, treatment or disposal
         facility, and any other business site or any other real property
         owned, leased, controlled or operated by the Corporation or by any
         predecessor thereof on or prior to the Closing Date.  As used in this
         Agreement, "ENVIRONMENTAL SITE LOSSES" shall mean any and all losses,
         damages (including exemplary damages and penalties), liabilities,
         claims, deficiencies, costs, expenses, and expenditures (including,
         without limitation, expenses in connection with site evaluations, risk
         assessments and feasibility studies) arising out of or required by an
         interim or final judicial or administrative decree, judgment,
         injunction, mandate, interim or final permit condition or restriction,
         cease and desist order, abatement order, compliance order, consent
         order, clean-up order, exhumation order, reclamation order or any
         other remedial action that is required to be undertaken under federal,
         state or local law in respect of operating activities on or affecting
         any Facility, any UST or any other Environmental Site, including, but
         not limited to (x) any actual or alleged violation of any law or
         regulation respecting the protection of the environment, including,
         but not limited to, RCRA and CERCLA or any other law or regulation
         respecting the protection of the air, water and land and (y) any
         remedies or violations, whether by a private or public action, alleged
         or sought to be assessed as a consequence, directly or indirectly, of
         any "Release" (as defined below) of pollutants (including odors) or
         Hazardous Substances from any Facility, any UST or any other
         Environmental Site resulting from activities thereat, whether such
         Release is into the air, water (including groundwater) or land and
         whether such Release arose before, during or after the Closing Date.
         The term "RELEASE" as used herein means any spilling, leaking,
         pumping, pouring, emitting, emptying, discharging, injecting,
         escaping, leaching, dumping or disposing into the ambient environment.
         Notwithstanding anything in this paragraph to the contrary, it is
         specifically understood and agreed that a Release composed solely of
         Hazardous Substances contained in household waste lawfully disposed of
         in a landfill during the time the Corporation owned





                                       30
<PAGE>   32
         and/or operated such landfill does not constitute an Environmental
         Site Loss.

                 (c)      All matters on Schedule 3.8 - Part II.

                 (d)      All actions, suits, proceedings, demands,
         assessments, adjustments, costs and expenses (including specifically,
         but without limitation, reasonable attorneys' fees and expenses of
         investigation) incident to any of the foregoing.

         7.2     LIMITATIONS ON SHAREHOLDERS' INDEMNITIES.

                 (a)      Except as may be otherwise covered by any policy of
         insurance carried by the Corporation, subject to the provisions of
         7.2(b) hereof, the obligations of the Shareholders to indemnify the
         WCI Indemnitees as provided in Section 7.1 shall be equal to the
         amount by which the cumulative amount of all such liabilities, claims,
         damages deficiencies, actions, suits, proceedings, demands,
         assessments, adjustments, costs and expenses, expenditures and
         Environmental Site Losses with respect to any or all 7.1 Indemnity
         Events exceed $40,000 (the "GENERAL DEDUCTIBLE AMOUNT"); provided,
         that the amount of any obligation of indemnity arising pursuant to
         Section 7.1(a) with respect to any representation, warranty or
         covenant contained in Sections 3.1 through 3.5, 3.12(c), 3.18, 3.22
         and 6.6 hereof and pursuant to Section 7.1(c) shall not be subject to
         the General Deductible Amount.

                 (b)      The maximum amount which WCI can recover as a result
         of one or more 7.1 Indemnity Events shall not exceed the Purchase
         Price (as adjusted pursuant to Section 1.2(a) hereof.

For this purpose, the Shares shall be valued at the $300,000 in the aggregate.

                 (c)      WCI shall use reasonable efforts to pursue any
insurance coverage it may have with respect to any matter resulting in a 7.1
Indemnity Event and shall apply any insurance recoveries it receives in
connection with any 7.1 Indemnity Event towards its recovery from the
Shareholder for such 7.1 Indemnity Event.  Nothing herein shall require WCI
from pursuing any such insurance coverage prior to pursuing any claim against
the Shareholder.

         7.3     NOTICE OF INDEMNITY CLAIM.

                 (a)      In the event that any claim ("CLAIM") is hereafter
         asserted against or arises with respect to any WCI Indemnitee as to
         which such Indemnitee may be entitled to indemnification hereunder,
         the WCI Indemnitee shall notify the Shareholders (as applicable
         collectively, the "INDEMNIFYING PARTY") in writing thereof (the
         "CLAIMS NOTICE") within 60 days after (i) receipt of written notice of
         commencement of any third party litigation against such WCI
         Indemnitee, (ii) receipt by such WCI Indemnitee of written notice of
         any third party claim pursuant to an invoice, notice of claim or
         assessment, against such WCI Indemnitee, or (iii) such WCI Indemnitee
         becomes aware of the existence of any other event in respect of which
         indemnification may be sought from the Indemnifying Party (including,
         without limitation, any inaccuracy of any representation or warranty
         or breach of any covenant).  The Claims Notice shall describe the
         Claim and the specific facts and circumstances in reasonable detail,
         and shall indicate the amount, if known, or an estimate, if possible,
         of the losses that have been or may be incurred or suffered by the WCI
         Indemnitee.

                 (b)      The Indemnifying Party may elect to defend any Claim
         for money damages where the cumulative total of all Claims (including
         such Claims) do not exceed the limit set forth in Section 7.2 at the
         time the Claim is made, by the Indemnifying Party's own counsel;
         provided, however, the Indemnifying Party may assume and undertake the
         defense of such a third party Claim only upon written agreement by the
         Indemnifying Party that the Indemnifying Party is obligated to fully
         indemnify the WCI Indemnitee with respect to such action.  The WCI
         Indemnitee may participate, at the WCI Indemnitee's own expense, in
         the defense of any Claim assumed by the Indemnifying Party.  Without
         the written approval of the WCI Indemnitee, which approval shall not
         be unreasonably withheld, the Indemnifying Party shall not agree to
         any compromise of a Claim defended by the Indemnifying Party.

                 (c)      If, within thirty (30) days of the Indemnifying
         Party's receipt of a Claims Notice, the Indemnifying Party shall not
         have provided the written agreement required by Section 7.3(b) and
         elected to defend the Claim, the WCI Indemnitee shall have the right
         to assume control of the defense and/or compromise of such Claim, and
         the costs and expenses of such defense, including reasonable
         attorneys' fees, shall be added to the Claim.  The Indemnifying Party
         shall promptly, and in any event within thirty (30) days after demand
         therefor, reimburse the WCI Indemnitee for the costs of defending the
         Claim, including attorneys' fees and expenses.

                 (d)      The party assuming the defense of any Claim shall
         keep the other party reasonably informed at all times of the progress
         and development of its or their defense of and compromise efforts with
         respect to such Claim and shall furnish the other party with copies of
         all relevant pleadings, correspondence and other papers.  In addition,
         the parties to this Agreement shall cooperate with each other and make
         available to each other and





                                       32
<PAGE>   34

         their representatives all available relevant records or other
         materials required by them for their use in defending, compromising or
         contesting any Claim.  The failure to timely deliver a Claims Notice
         or otherwise notify the Indemnifying Party of the commencement of such
         actions in accordance with this Section 7.3 shall not relieve the
         Indemnifying Party from the obligation to indemnify hereunder but only
         to the extent that the Indemnifying Party establishes by competent
         evidence that it has been prejudiced thereby.

                 (e)      In the event both the WCI Indemnitee and the
         Indemnifying Party are named as defendants in an action or proceeding
         initiated by a third party, they shall both be represented by the same
         counsel (on whom they shall agree), unless such counsel the WCI
         Indemnitee, or the Indemnifying Party shall determine that such
         counsel has a conflict of interest in representing both the WCI
         Indemnitee and the Indemnifying Party in the same action or proceeding
         and the WCI Indemnitee and the Indemnifying Party do not waive such
         conflict to the satisfaction of such counsel.

         7.4     SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  The
representations and warranties of the parties contained in this Agreement and
in any certificate, Exhibit or Schedule delivered pursuant hereto, or in any
other writing delivered pursuant to the provisions of this Agreement (the
"REPRESENTATIONS AND WARRANTIES") and the liability of the party making such
Representations and Warranties for breaches thereof shall survive the
consummation of the transactions contemplated hereby.  The parties hereto in
executing and delivering and in carrying out the provisions of this Agreement
are relying solely on the representations, warranties, Schedules, Exhibits,
agreements and covenants contained in this Agreement, or in any writing or
document delivered pursuant to the provisions of this Agreement, and not upon
any representation, warranty, agreement, promise or information, written or
oral, made by any persons other than as specifically set forth herein or
therein.  There are no third party beneficiaries to this Agreement other than
the WCI Indemnitees.

         7.5     NO EXHAUSTION OF REMEDIES OR SUBROGATION; RIGHT OF SET OFF.
The Shareholders waive any right to require any WCI Indemnitee to (i) proceed
against the Corporation; (ii) proceed against any other person; or (iii) pursue
any other remedy whatsoever in the power of any WCI Indemnitee.  WCI may, but
shall not be obligated to, set off against any and all payments due any
Shareholder any amount to which any WCI Indemnitee is entitled to be
indemnified hereunder with respect to any 7.1 Indemnity Event.  Such right of
set off shall be separate and apart from any and all other rights and remedies
that the Indemnities may have against Shareholders or their successors.

         8.1     RESTRICTIVE COVENANTS.  As to the Corporation, the

         limitation, know-how, trade secrets, customer lists, supplier lists,
         details of contracts, pricing policies, operational methods, marketing
         plans or strategies, bidding information, practices, policies or
         procedures, product development techniques or plans, and technical

         Shareholders or any Affiliate in any business endeavor owned or
         pursued by the Shareholders.

                 (e)      NO DISPARAGEMENT.  From and after the Closing Date,
         none of the Shareholders shall, in any way or to any person or entity
         or governmental or regulatory body or agency, denigrate or derogate
         WCI or any of its subsidiaries, or any officer, director or employee,
         or any product or service or procedure of any such company whether or
         not such denigrating or derogatory statements shall be true and are
         based on acts or omissions which are learned by the Shareholders from
         and after the date hereof or on acts or omissions which occur from and
         after the date hereof, or otherwise.  A statement shall be deemed
         denigrating or derogatory to any person or entity if it adversely
         affects the regard or esteem in which such person or entity is held by
         investors, lenders or licensing, rating, or regulatory entities.
         Without limiting the generality of the foregoing, none of the
         Shareholders shall, directly or indirectly in any way in respect of
         any such company or any such directors or officers, communicate with,
         or take any action which is adverse to the position of any such
         company with any person, entity or governmental or regulatory body or
         agency who or which has dealings or prospective dealings with any such
         company or jurisdiction or prospective jurisdiction over any such
         company.  This paragraph does not apply to the extent that testimony
         is required by legal process, provided that WCI has received not less
         than five days' prior written notice of such proposed testimony.

         8.2     RIGHTS AND REMEDIES UPON BREACH.  If any of the Shareholders
or any Affiliate breaches, or threatens to commit a breach of, any of the
provisions of Section 8.1 herein (the "RESTRICTIVE COVENANTS"), WCI shall have
the following rights and remedies, each of which rights and remedies shall be
independent of the others and severally enforceable, and each of which is in
addition to, and not in lieu of, any other rights and remedies available to WCI
at law or in equity:

                 (a)      SPECIFIC PERFORMANCE.  The right and remedy to have
         the Restrictive





                                       35
<PAGE>   37

         Covenants specifically enforced by any court of competent jurisdiction,
         it being agreed that any breach or threatened breach of the Restrictive
         Covenants would cause irreparable injury to WCI and that money damages
         would not provide an adequate remedy to WCI. Accordingly, in addition
         to any other rights or remedies, WCI shall be entitled to injunctive
         relief to enforce the terms of the Restrictive Covenants and to
         restrain the Shareholders from any violation thereof.

                 (b)      ACCOUNTING.  The right and remedy to require the
         Shareholders to account for and pay over to WCI all compensation,
         profits, monies, accruals, increments or other benefits derived or
         received by the Shareholders as the result of any transactions
         constituting a breach of the Restrictive Covenants.

                 (c)      SEVERABILITY OF COVENANTS.  The Shareholders
         acknowledge and agree that the Restrictive Covenants are reasonable
         and valid in geographical and temporal scope and in all other
         respects.  If any court determines that any of the Restrictive
         Covenants, or any part thereof, is invalid or unenforceable, the
         remainder of the Restrictive Covenants shall not thereby be affected
         and shall be given full effect, without regard to the invalid
         portions.

                 (d)      BLUE-PENCILING.  If any court determines that any of
         the Restrictive Covenants, or any part thereof, is unenforceable
         because of the duration or geographic scope of such provision, such
         court shall reduce the duration or scope of such provision, as the
         case may be, to the extent necessary to render it enforceable and, in
         its reduced form, such provision shall then be enforced.

                 (e)      ENFORCEABILITY IN JURISDICTION.  WCI and the
         Shareholders intend to and hereby confer jurisdiction to enforce the
         Restrictive Covenants upon the courts of any jurisdiction within the
         geographic scope of the Restrictive Covenants.  If the courts of any
         one or more of such jurisdictions hold the Restrictive Covenants
         unenforceable by reason of the breadth of such scope or otherwise, it
         is the intention of WCI and the Shareholders that such determination
         not bar or in any way affect WCI's right to the relief provided above
         in the courts of any other jurisdiction within the geographic scope of
         the Restrictive Covenants as to breaches of such covenants in such
         other respective jurisdictions, such covenants as they relate to each
         jurisdiction being, for this purpose, severable into diverse and
         independent covenants.

         Shareholders at Closing in cash by wire transfer or check payable in

         the Shareholders' Representative shall determine the actual Closing
         Date Current Assets and Closing Date Current Liabilities.  If the
         Closing Date Current Assets are greater than the Closing Date Current
         Liabilities, WCI shall promptly pay the difference between the two
         amounts to the Shareholders; if the Closing Date Current Liabilities
         are greater than the Closing Date Current Assets, the Shareholder
         shall promptly pay the difference between the two amounts to WCI;

                 (b)      Thirteen thousand six hundred and thirty-six (13,636)
         shares (the "SHARES") of WCI's Common Stock, $0.01 par value (the "WCI
         STOCK"), which shall be delivered by WCI to the Shareholders at the
         Closing.

                 (c)      WCI shall deliver to Timothy Thomas a promissory note
         (the "NOTE") in the form of Exhibit 1.2(d) hereto.  The Note shall be
         in an amount equal to thirty thousand dollars ($30,000) to be paid in
         twelve (12) equal monthly installments starting on the first day of
         the month following the Closing and continuing on the first day of
         each of the eleven months thereafter.  The Note shall be non-interest
         bearing and shall be secured by a lien on all of the assets of the
         Corporation.

         1.3     ALLOCATION OF THE PURCHASE PRICE.  Ten thousand dollars ($
10,000) of the Purchase Price shall be allocated to the covenant not to compete

shall be allocated to the Corporation's Stock.

         1.4     EXCLUDED ASSETS.  The Assets of the Corporation listed on

         1.5     PRICE PROTECTION FOR SHARES OF THE WCI STOCK.  If the gross
offering price of the WCI Stock in the IPO (as defined below), before
underwriting discounts and commissions and payment of expenses of the offering
(the "IPO PRICE"), is less than nine dollars ($9.00) per share, WCI will,
within 15 days after the closing of the IPO, issue to the Shareholders a number
of additional shares of the WCI Stock determined by multiplying (x) the
difference between the IPO Price and nine dollars ($9.00) and (y) 13,636 shares
and dividing that product by the IPO Price.  In lieu of issuing any fractional
shares, WCI shall pay cash to the Shareholders in an amount equal to the
fraction of a share that would have been delivered times the greater of the IPO
Price and nine dollars ($9.00).  For purposes of this agreement, "IPO" means a
public offering of the WCI Stock registered under the Securities Act of 1933
(the "ACT") and sold through underwriters pursuant to a firm commitment in the
amount of at least five million dollars at an IPO Price of at least five
dollars ($5.00) per share.  If the closing of the IPO shall not have occurred
by July 31, 1998, the Shareholders may, at their option exercised no later than
August 15, 1998, by written notice to WCI, cause WCI to repurchase all or any
portion of the WCI Stock issued to the Shareholders for eleven dollars ($11.00)
per share, payable by wire transfer to the account of the Shareholders.
Promptly upon exercise of such option, the Shareholders and WCI shall arrange
for a closing of the sale of such WCI Stock, such closing to occur no later
than August 31, 1998.

         2.      CLOSING TIME AND PLACE

         Subject to the terms and conditions of this Agreement, the closing of

State of Wyoming.  The Corporation has full corporate power and authority to
own and lease its properties and to carry on its business as now conducted.  As

security numbers or taxpayer identification numbers of the record and
beneficial owners thereof, the number of shares so owned, the allocation of the
cash and Shares among the Shareholders as agreed to among themselves, and wire

of record and beneficially by the Shareholders, as set forth in Schedule 3.2,
and are free and clear of all liens, security interests, encumbrances and

capital stock of the Corporation is duly and validly authorized and issued,
fully paid and nonassessable, and was not issued in violation of any preemptive
rights of any past or present shareholder of the Corporation.  No option,
warrant, call, conversion right or commitment of any kind (including any of the
foregoing created in connection with any indebtedness of the Corporation)
exists which obligates the Corporation to issue any of its authorized but
unissued capital stock or other equity interest or which obligates any
Shareholder to transfer the Corporation's Stock to any person.

Shareholders have full right, power and authority to enter into this Agreement
and to perform its, his or her obligations hereunder.  The execution and

transactions contemplated hereby by the Corporation have been duly authorized
by its Shareholders.  This Agreement has been duly and validly executed and
delivered by the Corporation and each of the Shareholders and, subject to the
due authorization, execution and delivery by WCI, constitutes the legal, valid
and binding obligation of the Corporation and each of the Shareholders
enforceable against each of them in accordance with its terms.

         3.5     NO BREACH OR DEFAULT.  Except as disclosed on Schedule 3.5,
the execution and delivery by the Corporation and the Shareholders of this
Agreement, and the consummation by the Shareholders of the transactions
contemplated hereby, will not:

         conditions of, or constitute a default under, or allow for the
         acceleration or termination of, or in any manner release any party
         from any obligation under, any mortgage, lease, note, bond, indenture,
         or material contract, agreement, license or other instrument or
         obligation of any kind or nature to which the Corporation or any of
         the Shareholders is a party, or by which the Corporation or the

         affected; or

                 (b)      violate any law or any order, writ, injunction or

         special use approvals or zoning variances, occupancy permits, and any
         other similar documents constituting a material authorization or
         entitlement or otherwise material to the operation of the business of
         the Corporation (collectively the "GOVERNMENTAL PERMITS") owned by,
         issued to, held by or otherwise benefitting the Corporation or the
         Shareholders as of the Closing Date.  The status of the Governmental
         Permits related to the disposal areas owned or used by the
         Corporation, including, without limitation, any conditions thereto

         Collection Franchises or other Governmental Permits required as a
         result of the consummation of the transactions contemplated by this
         Agreement.  All such consents, if any, have been obtained.  Except as

         result in the revocation, cancellation, suspension or adverse
         modification of any of the same.  Neither the Corporation nor any of
         the Shareholders has any knowledge of any reason why all such
         Governmental Permits and agreements will not remain in effect after

         policies or lawyer's title opinions relating to each Corporate
         Property.  All leases listed on Schedule 3.12(b) - Part I are in full
         force and effect and binding on the parties thereto; neither the
         Corporation nor any other party to any such lease is in breach of any
         of the material provisions thereof; the landlord's interest in any
         such lease has not been assigned to any third party nor has any such
         interest been mortgaged, pledged or hypothecated; and the Corporation
         has not assigned any such lease or sublet all or any part of the
         Corporate Property which is the subject of any such lease.  Except as
         described on Schedule 3.12(b) - Part II, there are no known material
         physical or mechanical defects in any Facility located on any
         Corporate Property.

         to all properties and assets, real, personal, and mixed, tangible and
         intangible, actually used or necessary for the conduct of its
         business, free of any encumbrance or charge of any kind except: (i)
         liens for current taxes not yet due; (ii) minor imperfections of title
         and encumbrances, if any, that are not substantial in amount, do not
         materially reduce the value or impair the use of the property subject
         thereto, do not materially impair the value of the Corporation, and
         have arisen only in the ordinary course of business and consistent
         with past practice; and (iii) the liens identified on Part III of
         Schedule 3.8 (collectively, the "PERMITTED LIENS") and those liens and
         encumbrances disclosed on Schedule 3.8-Part I.  Except as described on

         options, rights of first refusal or any other agreements or
         arrangements, either oral or written, that create or confer in any
         person or entity the right to acquire, occupy or possess, now or in
         the future, any Facility, any Corporate Property, or any portion
         thereof, or create in or confer on any person or entity any right,
         title or interest therein or

operation of the Corporation's business as presently conducted, without the
prior written consent of WCI.

         3.14    CONTRACTS AND AGREEMENTS; ADVERSE RESTRICTIONS.

                 (a)      Schedule 3.14(a) lists, as of the Closing Date, and
         includes copies of, all material contracts and agreements (other than
         leases and documents included with Schedule 3.12(b)) to which the
         Corporation is a party or by which it or any of its property is bound

         agreements, contracts with any labor organizations, promissory notes,
         loan agreements, bonds, mortgages, deeds of trust, liens, pledges,

         upon the parties thereto.  Except as described or cross referenced on
         Schedule 3.14(a), neither the Corporation nor, to the Corporation's or
         any of the Shareholder's knowledge, any other parties to such
         contracts and agreements is in breach thereof, and none of the parties
         has threatened to breach any of the material provisions thereof or
         notified the Corporation or any of the Shareholders of a default
         thereunder, or exercised any options thereunder.

                 (b)      Except as set forth on Schedule 3.14(b), there is no
         outstanding judgment, order, writ, injunction or decree against the
         Corporation, the result of which could materially adversely affect the
         Corporation or its business or any of the Corporate Properties, nor
         has the Corporation been notified that any such judgment, order, writ,
         injunction or decree has been requested.

         3.15    INSURANCE.  Schedule 3.15 is a complete list and includes

carried by the Corporation in respect of the Corporate Properties or any other
property used by the Corporation specifying, for each policy, the name of the
insurer, the type of risks insured, the deductible and limits of coverage, and
the annual premium therefor.  The Corporation currently carries insurance in
the type and amount ordinarily carried by owners or corporations in similar
circumstances, in respect to the Corporation' properties, assets and business.
During the last five years, there has been no lapse in any material insurance
coverage of the Corporation.  For each insurer providing coverage for any of
the contingent or other liabilities listed on Schedule 3.8, except to the
extent otherwise set forth in Part II of Schedule 3.8, each such insurer, if
required, has been properly and timely notified of such liability, no
reservation of rights letters have been received by the Corporation and the
insurer has assumed defense of each suit or legal proceeding.  All such
proceedings are fully covered by insurance, subject to normal deductibles.

         3.16    PERSONNEL.  Schedule 3.16 is a complete list, as of the

Corporation and their respective rates of compensation, including (i) the
portions thereof attributable to bonuses, (ii) any other salary, bonus, stock
option, equity participation, or other compensation arrangement made with or

         3.17    BENEFIT PLANS AND UNION CONTRACTS.

                 (a)      Schedule 3.17(a) is a complete list as of the Closing
         Date, and includes complete copies (or, in the case of oral
         arrangements, descriptions), of all employee benefit plans and
         agreements (written or oral) currently maintained or contributed to by
         the Corporation, including employment agreements and any other
         agreements containing "GOLDEN PARACHUTE" provisions, retirement plans,
         welfare benefit plans and deferred compensation agreements, together
         with copies of such plans, agreements and any trusts related thereto,
         and classifications of employees covered thereby as of the Closing
         Date.  Except for the employee benefit plans described on Schedule
         3.17(a), the Corporation has no other pension, retirement, welfare,
         profit sharing, deferred compensation, stock option, employee stock
         purchase or other employee benefit plans or arrangements with any
         party.  Except as disclosed on Schedule 3.17(a), all employee benefit
         plans listed on Schedule 3.17(a) are fully funded and in substantial
         compliance with all applicable federal, state and local statutes,
         ordinances and regulations.  All such plans that are intended to
         qualify under Section 401(a) of the Internal Revenue Code have been
         determined by the Internal Revenue Service to be so qualified, and
         copies of such determination letters are included as part of Schedule
         3.17(a).  Except as disclosed on Schedule 3.17(a), all reports and
         other documents required to be filed with any governmental agency or
         distributed to plan participants or beneficiaries (including, but not
         limited to, actuarial reports, audits or tax returns) have been timely
         filed or distributed, and copies thereof are included as part of
         Schedule 3.17(a).  All employee benefit plans listed on such Schedule
         have been operated in accordance with the terms and provisions of the
         plan documents and all related documents and policies.  The
         Corporation has not incurred any liability for excise tax or penalty
         due to the Internal Revenue Service or U.S. Department of Labor nor
         any liability to the Pension Benefit Guaranty Corporation for any
         employee benefit plan, nor has the Corporation, nor party-in-interest
         or disqualified person, engaged in any transaction or other activity
         which would give rise to such liability.  The Corporation has not
         participated in or made contributions to any "MULTI-EMPLOYER PLAN" as
         defined in the Employee Retirement Income Security Act of 1974
         ("ERISA"), nor would the Corporation or any affiliate be subject to
         any withdrawal liability with respect to such a plan if any such
         employer withdrew from such a plan immediately prior to the Closing
         Date.  No employee pension benefit plan is under funded on a
         termination basis as of the date of this Agreement.

                 (b)      Schedule 3.17(b) is a complete list, as of the
         Closing Date, and includes complete copies of all union contracts and
         agreements between the Corporation and any collective bargaining
         group.  The Corporation is in compliance in all material respects with
         all applicable federal and state laws respecting employment and
         employment





                                       11

         practices, terms and conditions of employment, wages and hours, and
         nondiscrimination in employment, and is not engaged in any unfair
         labor practice.  There is no charge pending or, to the Corporation's
         or the Shareholders' knowledge, threatened, against the Corporation
         before any court or agency and alleging unlawful discrimination in
         employment practices and there is no charge of or proceeding with
         regard to any unfair labor practice against it pending before the
         National Labor Relations Board.  There is no labor strike, dispute,
         slow down or stoppage as of the Closing Date, existing or threatened
         against the Corporation; no union organizational activity exists
         respecting employees of the Corporation not currently subject to a
         collective bargaining agreement; the union contracts or other
         agreements delivered as part of Schedule 3.17(b) constitute all
         agreements with the unions or other collective bargaining groups, and
         there are no other arrangements or established practices relating to
         the employees covered by any collective bargaining agreement; and
         Schedule 3.17(b) contains as of the date it is delivered a list of all
         arbitration or grievance proceedings that have occurred since the
         Balance Sheet Date.  No one has petitioned within the last five years,
         and no one is now petitioning, for union representation of any
         employees of the Corporation.  The Corporation has not experienced any
         labor strike, slow-down, work stoppage, labor difficulty or other job
         action during the last five years.

                 (c)      No payment made to any employee, officer, director or
         independent contractor of the Corporation (the "RECIPIENT") pursuant
         to any employment contract, severance agreement or other arrangement
         (the "GOLDEN PARACHUTE PAYMENT") will be nondeductible by the
         Corporation because of the application of Sections 280G and 4999 of
         the Code to the Golden Parachute Payment, nor will the Corporation be
         required to compensate any Recipient because of the imposition of an
         excise tax (including any interest or penalties related thereto) on
         the Recipient by reason of Sections 280G and 4999 of the Code.

         3.18    TAXES.

                 (a)      The Corporation has timely filed all requisite
         federal, state, local and other tax and information returns due for
         all fiscal periods ended on or before the Closing Date.  All such
         returns are accurate and complete.  Except as set forth on Schedule
         3.18, there are no open years (other than those within the statute of
         limitations), examinations in progress, extensions of any statute of
         limitations or claims against the Corporation relating to federal,
         state, local or other taxes (including penalties and interest) for any
         period or periods prior to and including the Closing Date and no
         notice of any claim for taxes has been received.  Copies of (i) any
         tax examinations, (ii) extensions of statutory limitations and (iii)
         the federal income, and state franchise, income and sales tax returns
         of the Corporation for its last three fiscal years are attached as
         part of Schedule 3.18.  Copies of all other federal, state, local and
         other tax and information returns for all prior years of the
         Corporation's existence have been made available to WCI and are among
         the records of the Corporation which will accrue to WCI at the
         Closing.  The Corporation has not been contacted by any federal, state
         or local taxing authority regarding a prospective examination.

                 (b)      Except as set forth on Schedule 3.18 (which schedule
         also includes the amount due with respect to the Corporation) the
         Corporation has duly paid all taxes and other related charges required
         to be paid prior to the Closing Date.  The reserves for taxes
         contained in the Financial Statements of the Corporation are adequate
         to cover its tax liability as of the Closing Date.

                 (c)      The Corporation has withheld all required amounts
         from its employees for all pay periods in full and complete compliance
         with the withholding provisions of applicable federal, state and local
         laws.  All required federal, state and local and other returns with
         respect to income tax withholding, social security, and unemployment
         taxes have been duly filed by the Corporation for all periods for
         which returns are due, and the amounts shown on all such returns to be
         due and payable have been paid in full.

         3.19    COPIES COMPLETE; REQUIRED CONSENTS.  Except as disclosed on
Schedule 3.19, the copies of the Articles of Incorporation of the Corporation,
both as amended to the Closing Date, and the copies of all leases, instruments,
agreements, licenses, permits, certificates or other documents that have been
delivered to WCI in connection with the transactions contemplated hereby are
complete and accurate as of the Closing Date and are true and correct copies of
the originals thereof.  Except as specifically disclosed on Schedule 3.19, the
rights and benefits of the Corporation will not be adversely affected by the
transactions contemplated hereby, and the execution of this Agreement and the
performance of the obligations hereunder will not violate or result in a breach
or constitute a default under any of the terms or provisions thereof.  None of
such leases, instruments, agreements, licenses, permits, site assessments,
certificates or other documents requires notice to, or consent or approval of,
any governmental agency or other third party to any of the transactions
contemplated hereby, except the Required Governmental Consents, such consents
and approvals as are listed on Schedule 3.19; all of which will have been given
or obtained prior to the Closing.

         3.20    CUSTOMERS, BILLINGS, CURRENT RECEIPTS AND RECEIVABLES.
Schedule 3.20 is a current, accurate and complete list of, and includes:

                 (a)      the customers the Corporation serves on an ongoing
         basis, including name, location and current billing rate, as of the

                 (c)      the average monthly revenues of the Corporation
         derived from billings to its customers for each of the twelve months
         preceding the Closing Date.  Except as set forth on Schedule 3.20, the
         Corporation and the Shareholders have no knowledge of any reason why
         the Corporation's average monthly revenues derived from billings to
         its customers after the Closing Date should not continue at
         approximately the same rate as before the Closing Date.

         3.21    NO CHANGE WITH RESPECT TO THE CORPORATION.  Except as set
forth on

         adversely affecting its business or future prospects;

         Affiliates, other than in the ordinary course of business;

                 (h)      any cancellation, or agreement to cancel, any

         Closing Date, of (i) the amount of the aggregate debt (excluding trade
         payables) of the Corporation outstanding on the Closing Date required
         to be repaid by WCI at the Closing or immediately after the Closing
         Date and all prepayment penalties incurred or to be incurred by WCI or
         the Corporation in connection with the repayment of any such debt,
         (ii) the amount of the aggregate debt (excluding trade payables) of
         the Corporation outstanding on the Closing Date which will remain

         recent borrowing to finance equipment, of all lease obligations of the
         Corporation that are not capitalized lease obligations and (iv) the
         aggregate amount of the present value of all capitalized lease
         obligations (determined in accordance with generally accepted
         accounting principles) of the Corporation (the "CLOSING DATE DEBT").
         Schedule 3.22(a) shall include wire transfer instructions for
         creditors whose Closing Date Debt WCI has designated for payment, and

<PAGE>   22

         WCI as such Shareholder feels is reasonably necessary to make an
         informed investment decision with respect to the Shares, including,
         without limitation, WCI's Prospectus dated May, 1998.  Each of the
         Shareholders understands that the Shares are not covered by the

         Shareholders to provide them information about WCI.

                 (d)      Each of the Shareholders has had the opportunity to
         ask questions and receive answers concerning the terms and conditions
         of the transactions contemplated by this Agreement and to obtain
         additional information that WCI possesses or can obtain without
         unreasonable effort or expense that is necessary to verify the
         accuracy of the information provided.

                 (e)      Each of the Shareholders is acquiring the Shares
         pursuant to this Agreement for its own account, not as a nominee or

         of the Shares.

                 (f)      Each of the Shareholders is able to bear the economic
         risk of such an investment in the Shares is aware that he, she or it
         must be prepared to hold such Shares for an indefinite period (unless
         exempt from registration or subsequently registered under the Act or
         as otherwise provided in Section 1.5) and is aware that the Shares
         have not been registered under the Act, or registered or qualified
         under the securities laws of any state, on the ground, among others,
         that no unregistered distribution or public offering of Shares is to
         be effected and the Shares are being issued by WCI without any public
         offering within the meaning of section 4(2) of the Act.

                 (g)      Without in any way limiting the representations

         any interest in them, unless and until prior to any proposed
         encumbrance, pledge, hypothecation, sale, transfer, assignment or
         other disposition, (i) a registration statement on Form S-1 or S-3 (or
         any other form appropriate for the purpose or replacing such form)
         under the Act with respect to the shares proposed to be transferred or
         otherwise disposed of shall be then effective (ii)(a) he, she or it
         shall have furnished WCI with a detailed statement of the
         circumstances of the proposed disposition, and (b) he, she or it shall
         have furnished WCI with an opinion of counsel or no-action letter
         issued by the Staff of the Securities and Exchange Commission ("SEC")
         (obtained at the Shareholders' expense) in form and substance
         satisfactory to WCI to the effect that such disposition will not
         require registration of any such Shares under the Act or qualification
         of any such Shares under any other securities law; or (iii) Rule 144
         is available with respect to such transaction.

                 (h)      Each of the Shareholders understands and agrees that
         each certificate or other instrument representing the Shares will bear
         a legend on the face thereof (or on the reverse thereof with a
         reference to such legend on the face thereof) which legend restricts
         the sale, transfer or other disposition of the Shares otherwise than
         in accordance with Sections 3.38(g) of this Agreement provided,
         however, that WCI shall, on the request of





                                       21
<PAGE>   23

         any of the Shareholders, cause such legends to be removed from the
         certificates or other instrument evidencing the Shares if such
         Shareholder has held such Shares for the period contemplated by Rule
         144(k) under the Act and if the Shareholder is not then and has not
         been during the three months preceding such request an affiliate of
         WCI (as defined in Rule 144 under the Act).

                 (i)      Each of the Shareholders understands and agrees that
         the Shares will be "RESTRICTED SECURITIES" as that term is defined in
         Rule 144 under the Act and, accordingly, that the Shares must be held
         indefinitely unless subsequently registered under the Act or an
         exemption from such registration is available.

                 (j)      The Shareholders agree to be bound with respect to
         the Shares by any "LOCK UP" provisions to which the executive officers
         and directors of WCI are also bound as may be requested by any
         underwriters of any offering of WCI Stock or securities convertible
         into WCI Stock.

         3.39    S CORPORATION.  The Corporation has elected to be taxed as an

                  SHAREHOLDERS

         6.1     RELEASE OF GUARANTIES.  WCI shall use reasonable efforts to
obtain the termination and release promptly after the Closing Date of the
personal guaranties of the Shareholders listed on Schedule 6.2, all of which
relate to indebtedness of the Corporation included in the Financial Statements
as of the Balance Sheet Date or WCI shall indemnify the Shareholders and hold
them harmless from and against all losses, expenses or claims by third parties
to enforce or collect indebtedness owed by the Corporation as of the Closing
Date which is personally guaranteed by the Shareholders pursuant to such
guaranties.  The Shareholders may notify the obligees under such guaranties
that they have terminated their obligations under such guaranties.  The
Shareholders shall cooperate with WCI in obtaining such releases.

         6.2     RELEASE OF SECURITY INTERESTS.  On or after the Closing Date,
the Shareholders and their respective Affiliates shall cause those security
interests in the assets of the Corporation that have been created in favor of
financial institutions or  other lenders to secure indebtedness (other than
indebtedness of the Corporation) of the Shareholders or their respective
Affiliates to be released in a manner reasonably satisfactory to WCI, and shall
cause all guaranties by the Corporation relating to the indebtedness of the
Shareholders to be released to the reasonable satisfaction of WCI.

         6.3     CONFIDENTIALITY.  Neither the Corporation nor any of the
Shareholders shall disclose or make any public announcements of the
transactions contemplated by this Agreement without the prior written consent
of WCI, unless required to make such disclosure or announcement by law, in
which event the party making the disclosure or announcement shall notify WCI at
least 24 hours before such disclosure or announcement is expected to be made.
WCI shall not disclose or make any public announcement of the transactions
contemplated by this Agreement without the prior written consent of the
Shareholders' Representative, unless in connection with the initial public
offering of WCI Stock or otherwise required to make such disclosure or
announcement by law, in which event WCI shall notify the Shareholders'
Representative at least 24 hours before such disclosure or announcement is
expected to be made.

         6.4     BROKERS AND FINDERS FEES.  Each party shall pay and be
responsible for any broker's, finder's or financial advisory fee incurred by

Shareholders arising out of the Shareholders' ownership of the Corporation
prior to the Closing, including matters relating to tax returns and any tax
audits, appeals, claims or litigation with respect to such tax returns or the
preparation of such tax returns.  In connection therewith, WCI shall make
available to the Shareholders such files, documents, books and records of the
Corporation for inspection and copying as may be reasonably requested by the
Shareholders and shall cooperate with the Shareholders with respect to
retaining information and documents which relate to such matters.

         6.6     SHORT YEAR TAX RETURNS.  After the Closing Date, the
Shareholders shall prepare at their sole cost and expense, all short year
federal, state, county, local and foreign tax returns required by law for the
period beginning with the first day of the Corporation's fiscal year in which
the Closing occurs and ending with the Closing Date.  Each such return shall be
prepared in a financially responsible and conservative manner and shall be
delivered to WCI together with all necessary supporting schedules within 120
days following the Closing Date for its approval (but such approval shall not
relieve the Shareholders of their responsibility for the taxes assessed under
these returns).  The Shareholders shall be responsible for the payment of all
taxes shown to be due or that may come to be due on such returns or otherwise
relating to the period prior to the Closing Date in excess of the amount of any
reserve for taxes included in Effective Date Current Liabilities.  The
Shareholders shall also be responsible for all taxes arising from the
conversion of the Corporation from a cash to accrual basis of reporting whether
or not due on such returns or on the first return filed by the Corporation for
the period commencing after the Closing Date.  At the time of the delivery of
the returns, shall contemporaneously deliver to WCI checks payable to the
respective taxing authorities in amounts equal to the amount due.  WCI shall
sign tax returns and cause such returns to be timely filed with the appropriate
authorities.  The Shareholders shall be entitled to receive all refunds shown
on said returns and any such refunds received by the Corporation or WCI shall
be remitted to the Shareholders.

         6.7     CERTAIN TAX MATTERS.  The Shareholders acknowledge that WCI
may make an election under Section 338(h)(10) of the Internal Revenue Code of
1986, as amended.  The Shareholders agree that WCI, in its discretion, may make
such election; provided, however, that such election shall be made no later
than the due date for such election.  If such election is made by WCI:

                 (a)      WCI shall be authorized to complete Form 8023-A;

                 (b)      The Shareholders shall sign such completed Form
         8023-A at the Closing; and

                 (c)      WCI and the Shareholders shall agree upon the
         allocation of the Purchase Price among the assets (including
         intangible assets) of the Corporation.

                 (d)      If WCI does make its election under Section
         338(h)(10) of the Internal Revenue Code of 1986, as amended, WCI shall
         reimburse the Shareholders and the Corporation for any additional
         taxes, penalties, interest and costs of preparation of amended income
         tax returns incurred due to such election resulting from the recapture
         of depreciation previously taken on various assets of the Corporation
         at ordinary income instead of capital gain rates.  Such reimbursement
         shall be in a sum computed by a simultaneous equation computing the
         additional tax owed by stockholders, as well as the tax on the payment
         of that sum.

         6.8     SHAREHOLDERS' REPRESENTATIVE.

                          (a)     In order to administer efficiently the rights
         and obligations of the Shareholders under this Agreement, the
         Shareholders hereby designate and appoint Timothy Thomas as the
         Shareholders' Representative, to serve as the Shareholders' agent,
         proxy and attorney-in-fact for the limited purposes set forth in this
         Agreement.

                          (b)     Each of the Shareholders hereby appoints the
         Shareholders' Representative as such Shareholder's agent, proxy and
         attorney-in-fact, with full power of substitution, for all purposes
         set forth in this Agreement, including, without limitation, the full
         power and authority on such Shareholder's behalf (i) to consummate the
         transactions contemplated by this Agreement, (ii) to disburse any
         funds received hereunder to the Shareholders, (iii) to execute and
         deliver on behalf of each Shareholder any amendment or waiver under
         this Agreement, to agree to the amount of the actual Closing Date
         Debt, Closing Date Current Assets and Closing Date Current Liabilities
         pursuant to Section 1.2(a), and to agree to resolution of all Claims
         hereunder, (iv) to retain legal counsel and other professional
         services, at the expense of the Shareholders, in connection with the
         performance by the Shareholders' Representative of this Agreement, and
         (v) to do each and every act and exercise any and all rights which
         such Shareholder or Shareholders are permitted or required to do or
         exercise under this Agreement and the other agreements, documents and
         certificates executed in connection herewith.  Each of the
         Shareholders agrees that such agency and proxy are coupled with an
         interest, are therefore irrevocable without the consent of the
         Shareholders' Representative and shall survive the death, bankruptcy
         or other incapacity of any Shareholder.

                          (c)     Each of the Shareholders hereby agrees that
         any amendment or waiver under this Agreement, and any action taken on
         behalf of the Shareholders to enforce the rights of the Shareholders
         under this Agreement, and any action taken with respect to any
         adjustment or Claim (including any action taken to object to, defend,
         compromise or agree to the payment of such adjustment or Claim), shall
         be effective if approved in writing by persons who were the holders of
         a majority of the Corporation's Stock immediately prior to the
         Closing, and that each and every action so taken shall be binding and
         conclusive on every Shareholder, whether or not such Shareholder had
         notice of, or approved, such amendment or waiver.

                          (d)     Timothy Thomas shall serve as the
         Shareholders' Representative until he resigns or is otherwise unable
         or unwilling to serve.  In the event that a Shareholders'
         Representative resigns from such position or is otherwise unable or
         unwilling to serve, the remaining Shareholders shall select, by the
         vote of the holders of a majority of the Corporation's Stock
         immediately prior to the Closing, a successor representative to fill
         such vacancy, shall provide prompt written notice to WCI of such
         change and such substituted representative shall then be deemed to be
         the Shareholders' Representative for all purposes of this Agreement.

         6.9     GENERAL RELEASE BY SHAREHOLDERS.  Each of the Shareholders
         hereby fully





                                       27
<PAGE>   29
releases and discharges the Corporation and its directors, officers, agents and
employees from all rights, claims and actions, known or unknown, of any kind
whatsoever, which any of such Shareholders now has or may hereafter have
against the Corporation and its directors, officers, agents and employees,
arising out of or relating to events arising prior to or on the Closing Date,
except (a) as may be described in written contracts disclosed in Schedule 6.9
and expressly described and specifically excepted from this release in Schedule
6.9, (b) compensation as an employee of the Corporation for current periods
expressly described and excepted from such release on schedule 6.9, and (c) for
the obligations of the Corporation arising after the Closing Date under this
Agreement.  Specifically, but not by way of limitation, each of the
Shareholders waives any right of indemnification, contribution or other
recourse against the Corporation which he now has or may hereafter have against
the Corporation with respect to representations, warranties or covenants made
in this Agreement by the Corporation.

                 Each of the Shareholders hereby waives and relinquishes all
rights and benefits afforded by Section 1542 of the California Civil Code,
which states as follows:

                 "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS TO WHICH THE
                 CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE
                 TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
                 MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

Each of the Shareholders understands and acknowledges the significance and
consequence of this waiver of Section 1542 and nevertheless elects to, and
does, release those claims described in this Section 6.9, known or unknown,
that it may have now or in the future arising out of or relating to any event
arising on or prior to the date of this Agreement.

         7.      INDEMNIFICATION

         7.1     INDEMNITY BY THE SHAREHOLDERS.  Each of the Shareholders,
jointly and severally, subject to the limitations set forth in Section 7.2,
covenants and agrees that he or she will indemnify and hold harmless WCI, the
Corporation and their respective directors, officers and agents and their
respective successors and assigns (collectively the "WCI INDEMNITEES"), from
and after the date of this Agreement and until the third anniversary of the
Closing Date, against any and all losses, damages, assessments, fines,
penalties, adjustments, liabilities, claims, deficiencies, costs, expenses
(including specifically, but without limitation, reasonable attorneys' fees and
expenses of investigation), expenditures, including, without limitation, any
"ENVIRONMENTAL SITE LOSSES" (as such term is hereinafter defined) identified by
a WCI Indemnitee in a Claims Notice (as defined in Section 7.3(a)), or asserted
by a WCI Indemnitee in litigation commenced against the Shareholders provided
that in either case any such Claims Notice shall be given or the litigation
commenced prior to the earlier of the third anniversary of this Agreement or
the expiration of the applicable statute of limitations (irrespective of the
date of discovery), with respect to each of the following contingencies (all,
the "7.1 INDEMNITY EVENTS"):

                 (a)      Any misrepresentation, breach of warranty, or
         nonfulfillment of any agreement or covenant on the part of the
         Shareholders or the Corporation pursuant to the





                                       28
<PAGE>   30

         terms of this Agreement or any misrepresentation in or omission from
         any Exhibit, Schedule, list, certificate, or other instrument
         furnished or to be furnished to WCI pursuant to the terms of this
         Agreement, regardless of whether, in the case of a breach of a
         representation or a warranty, WCI relied on the truth of such
         representation or warranty or had any knowledge of any breach thereof.

                 (b)      The design, development, construction or operation of
         any Facility or any other "ENVIRONMENTAL SITE" as hereinafter defined,
         or the installation or operation of a UST during any period on or
         prior to the Closing Date, in excess of the amount of liability with
         respect thereto, if any, set forth on Part II of Schedule 3.8.  As
         used in this Agreement, "ENVIRONMENTAL SITE" shall mean any Facility,
         any UST and any other waste storage, processing, treatment or disposal
         facility, and any other business site or any other real property
         owned, leased, controlled or operated by the Corporation or by any
         predecessor thereof on or prior to the Closing Date.  As used in this
         Agreement, "ENVIRONMENTAL SITE LOSSES" shall mean any and all losses,
         damages (including exemplary damages and penalties), liabilities,
         claims, deficiencies, costs, expenses, and expenditures (including,
         without limitation, expenses in connection with site evaluations, risk
         assessments and feasibility studies) arising out of or required by an
         interim or final judicial or administrative decree, judgment,
         injunction, mandate, interim or final permit condition or restriction,
         cease and desist order, abatement order, compliance order, consent
         order, clean-up order, exhumation order, reclamation order or any
         other remedial action that is required to be undertaken under federal,
         state or local law in respect of operating activities on or affecting
         any Facility, any UST or any other Environmental Site, including, but
         not limited to (x) any actual or alleged violation of any law or
         regulation respecting the protection of the environment, including,
         but not limited to, RCRA and CERCLA or any other law or regulation
         respecting the protection of the air, water and land and (y) any
         remedies or violations, whether by a private or public action, alleged
         or sought to be assessed as a consequence, directly or indirectly, of
         any "RELEASE" (as defined below) of pollutants (including odors) or
         Hazardous Substances from any Facility, any UST or any other
         Environmental Site resulting from activities thereat, whether such
         Release is into the air, water (including groundwater) or land and
         whether such Release arose before, during or after the Closing Date.
         The term "RELEASE" as used herein means any spilling, leaking,
         pumping, pouring, emitting, emptying, discharging, injecting,
         escaping, leaching, dumping or disposing into the ambient environment.
         Notwithstanding anything in this paragraph to the contrary, it is
         specifically understood and agreed that a Release composed solely of
         Hazardous Substances contained in household waste lawfully disposed of
         in a landfill during the time the Corporation owned and/or operated
         such landfill does not constitute an Environmental Site Loss.

                 (c)      All matters on Schedule 3.8, Part II.

                 (d)      All actions, suits, proceedings, demands,
         assessments, adjustments, costs and expenses (including specifically,
         but without limitation, reasonable attorneys' fees and expenses of
         investigation) incident to any of the foregoing.

         7.2     LIMITATIONS ON SHAREHOLDERS' INDEMNITIES.

                 (a)      Subject to the provisions of 7.2(b) hereof, the
         obligations of the Shareholders to indemnify the WCI Indemnitees as
         provided in Section 7.1 shall be equal to the amount by which the
         cumulative amount of all such liabilities, claims, damages
         deficiencies, actions, suits, proceedings, demands, assessments,
         adjustments, costs and expenses, expenditures and Environmental Site
         Losses with respect to any or all 7.1 Indemnity Events exceed five
         thousand dollars ($5,000) (the "GENERAL DEDUCTIBLE AMOUNT").

                 (b)      The maximum amount which WCI can recover as a result
         of one or more 7.1 Indemnity Events shall not exceed:

                          (i)     eighty percent (80%) of the Purchase Price
         (as adjusted pursuant to Section 1.2(a) hereof), if the 7.1 Indemnity
         Event occurs during the time period from the Closing Date to, and
         including, the first anniversary of the Closing Date;

                          (ii)    seventy-five percent (75%) of the Purchase
         Price (as adjusted pursuant to Section 1.2(a) hereof), if the 7.1
         Indemnity Event occurs during the time period from the first
         anniversary of the Closing Date to, and including, the second
         anniversary of the Closing Date; and

                          (iii)   sixty-five percent (65%) of the Purchase
         Price (as adjusted pursuant to Section 1.2(a) hereof), if the 10.1
         Indemnity Event occurs during the time period from the second
         anniversary of the Closing Date to, and including, the third
         anniversary of the Closing Date.

For this purpose, the Shares shall be valued at one hundred and fifty thousand
dollars ($150,000).

         7.3     NOTICE OF INDEMNITY CLAIM.

                 (a)      In the event that any claim ("CLAIM") is hereafter
         asserted against or arises with respect to any WCI Indemnitee as to
         which such Indemnitee may be entitled to indemnification hereunder,
         the WCI Indemnitee shall notify the Shareholders (as applicable
         collectively, the "INDEMNIFYING PARTY") in writing thereof (the
         "CLAIMS NOTICE") within 60 days after (i) receipt of written notice of
         commencement of any third party litigation against such WCI
         Indemnitee, (ii) receipt by such WCI Indemnitee of written notice of
         any third party claim pursuant to an invoice, notice of claim or
         assessment, against such WCI Indemnitee, or (iii) such WCI Indemnitee
         becomes aware of the existence of any other event in respect of which
         indemnification may be sought from the Indemnifying Party (including,
         without limitation, any inaccuracy of any representation or warranty
         or breach of any covenant).  The Claims Notice shall describe the
         Claim and the specific facts and circumstances in reasonable detail,
         and shall indicate the amount, if known, or an estimate, if possible,
         of the losses that have been or may be incurred or suffered by the WCI
         Indemnitee.

                 (b)      The Indemnifying Party may elect to defend any Claim
         for money damages where the cumulative total of all Claims (including
         such Claims) do not exceed the limit set forth in Section 7.2(b) at
         the time the Claim is made, by the Indemnifying Party's own counsel;
         provided, however, the Indemnifying Party may assume and undertake the
         defense of such a third party Claim only upon written agreement by the
         Indemnifying Party that the Indemnifying Party is obligated to fully
         indemnify the WCI Indemnitee with respect to such action.  The WCI
         Indemnitee may participate, at the WCI Indemnitee's own expense, in
         the defense of any Claim assumed by the Indemnifying Party.  Without
         the written approval of the WCI Indemnitee, which approval shall not
         be unreasonably withheld, the Indemnifying Party shall not agree to
         any compromise of a Claim defended by the Indemnifying Party.

                 (c)      If, within thirty (30) days of the Indemnifying
         Party's receipt of a Claims Notice, the Indemnifying Party shall not
         have provided the written agreement required by Section 7.3(b) and
         elected to defend the Claim, the WCI Indemnitee shall have the right
         to assume control of the defense and/or compromise of such Claim, and
         the costs and expenses of such defense, including reasonable
         attorneys' fees, shall be added to the Claim.  The Indemnifying Party
         shall promptly, and in any event within thirty (30) days after demand
         therefor, reimburse the WCI Indemnitee for the costs of defending the
         Claim, including attorneys' fees and expenses.

                 (d)      The party assuming the defense of any Claim shall
         keep the other party reasonably informed at all times of the progress
         and development of its or their defense of and compromise efforts with
         respect to such Claim and shall furnish the other party with copies of
         all relevant pleadings, correspondence and other papers.  In addition,

         deliver a Claims Notice or otherwise notify the Indemnifying Party of
         the commencement of such actions in accordance with this Section 7.3
         shall not relieve the Indemnifying Party from the obligation to
         indemnify hereunder but only to the extent that the Indemnifying Party
         establishes by competent evidence that it has been prejudiced thereby.

                 (e)      In the event both the WCI Indemnitee and the
         Indemnifying Party are named as defendants in an action or proceeding
         initiated by a third party, they shall both be represented by the same
         counsel (on whom they shall agree), unless such counsel the WCI
         Indemnitee, or the Indemnifying Party shall determine that such
         counsel has a conflict of interest in representing both the WCI
         Indemnitee and the Indemnifying Party in the same action or proceeding
         and the WCI Indemnitee and the Indemnifying Party do not waive such
         conflict to the satisfaction of such counsel.

         7.4     SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  The
representations and warranties of the parties contained in this Agreement and
in any certificate, Exhibit or Schedule delivered pursuant hereto, or in any
other writing delivered pursuant to the provisions of this Agreement (the
"REPRESENTATIONS AND WARRANTIES") and the liability of the party making such
Representations and Warranties for breaches thereof shall survive the
consummation of the transactions contemplated hereby.  The parties hereto in
executing and delivering and in carrying out the provisions of this Agreement
are relying solely on the representations, warranties, Schedules, Exhibits,
agreements and covenants contained in this Agreement, or in any writing or
document delivered pursuant to the provisions of this Agreement, and not upon
any representation, warranty, agreement, promise or information, written or
oral, made by any persons other than as specifically set forth herein or
therein.

         7.5     NO EXHAUSTION OF REMEDIES OR SUBROGATION; RIGHT OF SET OFF.
The Shareholders waive any right to require any WCI Indemnitee to (i) proceed
against the Corporation; (ii) proceed against any other person; or (iii) pursue
any other remedy whatsoever in the power of any WCI Indemnitee.  WCI may, but
shall not be obligated to, set off against any and all payments due any
Shareholder any amount to which any WCI Indemnitee is entitled to be
indemnified hereunder with respect to any 7.1 Indemnity Event.  Such right of
set off shall be separate and apart from any and all other rights and remedies
that the Indemnities may have against Shareholders or their successors.

         8.      OTHER POST-CLOSING COVENANTS OF THE SHAREHOLDERS AND WCI

         8.1     RESTRICTIVE COVENANTS.  As to the Corporation, the
Shareholders and their Affiliates acknowledge that (i) WCI, as the purchaser of
the Corporation's Stock, is and will be engaged in the same business as the
Corporation (the "BUSINESS"); (ii) the Shareholders and their Affiliates are
intimately familiar with the Business; (iii) the Business is currently
conducted in the State of Wyoming and WCI intends to continue the Business in
Wyoming and intends, by acquisition or otherwise, to expand the Business into
other geographic areas of Wyoming where it is not presently conducted; (iv) the
Shareholders and their Affiliates have had access to trade secrets of, and
confidential information concerning, the Business; (v) the agreements and
covenants contained in this Section 8.1 are essential to protect the Business
and the goodwill being acquired; and (vi) the Shareholders and their Affiliates
have the means to support themselves and their dependents other than by
engaging in a business substantially similar to the Business and the provisions
of this Section 8 will not impair such ability.  The Shareholders covenant and
agree as set forth in (a), (b) and (c) below with respect to the Corporation:

                 (a)      NON-COMPETE.  For a period commencing on the Closing
         Date and terminating five years thereafter (the "RESTRICTED PERIOD"),
         neither the Shareholders nor any of their Affiliates shall, anywhere
         in the counties of Albany, Crook, Campbell, Converse, Goshen,
         Niobrara, Natrona, Platte or Weston, Wyoming, where WCI or one of its
         subsidiaries owns or operates a business similar to the Business (the
         "RESTRICTED COUNTIES"), directly or indirectly, acting individually or
         as the owner, shareholder, partner, or employee of any entity, (i)
         engage in the operation of a solid waste collection, transporting,
         disposal and/or composting business, transfer facility, recycling
         facility, materials recovery facility or solid waste landfill; (ii)
         enter the employ of, or render any personal services to or for the
         benefit of, or assist in or facilitate the solicitation of customers
         for, or receive remuneration in the form of salary, commissions or
         otherwise from, any business engaged in such activities; (iii) as
         owner or lessor of real estate or personal property, rent to lease any
         facility, equipment or other assets to any business engaged in the
         same business as the Corporation; or (iv) receive or purchase a
         financial interest in, make a loan to, or make a gift in support of,
         any such business in any capacity, including, without limitation, as a
         sole proprietor, partner, shareholder, officer, director, principal,
         agent, trustee or lender; provided, however, that any of the
         Shareholders may own, directly or indirectly, solely as an investment,
         securities of any business traded on any national securities exchange
         or NASDAQ, provided none of the Shareholders is a controlling person
         of, or a member of a group which controls, such business and further
         provided that the Shareholders do not, in the aggregate, directly or
         indirectly, own 2% or more of any class of securities of such
         business.

                 (b)      CONFIDENTIAL INFORMATION.  During the Restricted
         Period and thereafter, the Shareholders and their Affiliates shall
         keep secret and retain in strictest confidence, and shall not use for
         the benefit of themselves or others, all data and information relating
         to the Business ("CONFIDENTIAL INFORMATION"), including without
         limitation, know-how, trade secrets, customer lists, supplier lists,
         details of contracts, pricing policies,





                                       33
<PAGE>   35

         operational methods, marketing plans or strategies, bidding
         information, practices, policies or procedures, product development
         techniques or plans, and technical processes; provided, however, that
         the term "CONFIDENTIAL INFORMATION" shall not include information that
         (i) is or becomes generally available to the public other than as a
         result of disclosure by the Shareholders or (ii) is general knowledge
         in the solid waste handling and landfill business and not specifically
         related to the Business.

                 (c)      PROPERTY OF THE BUSINESS.  All memoranda, notes,
         lists, records and other documents or papers (and all copies thereof)
         relating to the Business, including such items stored in computer
         memories, on microfiche or by any other means, made or compiled by or
         on behalf of the Shareholders or the Corporation or made available to
         them relating to the Business, but excluding any materials (other than
         the minute books of the Corporation) maintained by any attorneys for
         the Corporation or the Shareholders prior to the Closing, are and
         shall be the property of WCI and have been delivered or will be
         delivered or made available to WCI at the Closing.

                 (d)      NON-SOLICITATION.  Without the consent of WCI, which
         may be granted or withheld by WCI in its discretion, the Shareholders
         and their Affiliates shall not solicit any employees of the
         Corporation to leave the employ of the Corporation and join the
         Shareholders or any Affiliate in any business endeavor owned or
         pursued by the Shareholders.

                 (e)      NO DISPARAGEMENT.  From and after the Closing Date,
         none of the Shareholders shall, in any way or to any person or entity
         or governmental or regulatory body or agency, denigrate or derogate
         WCI or any of its subsidiaries, or any officer, director or employee,
         or any product or service or procedure of any such company whether or
         not such denigrating or derogatory statements shall be true and are
         based on acts or omissions which are learned by the Shareholders from
         and after the date hereof or on acts or omissions which occur from and
         after the date hereof, or otherwise.  A statement shall be deemed
         denigrating or derogatory to any person or entity if it adversely
         affects the regard or esteem in which such person or entity is held by
         investors, lenders or licensing, rating, or regulatory entities.
         Without limiting the generality of the foregoing, none of the
         Shareholders shall, directly or indirectly in any way in respect of
         any such company or any such directors or officers, communicate with,
         or take any action which is adverse to the position of any such
         company with any person, entity or governmental or regulatory body or
         agency who or which has dealings or prospective dealings with any such
         company or jurisdiction or prospective jurisdiction over any such
         company.  This paragraph does not apply to the extent that testimony
         is required by legal process, provided that WCI has received not less
         than five days' prior written notice of such proposed testimony.

         8.2     RIGHTS AND REMEDIES UPON BREACH.  If any of the Shareholders
or any Affiliate breaches, or threatens to commit a breach of, any of the
provisions of Section 8.1 herein (the "RESTRICTIVE COVENANTS"), WCI shall have
the following rights and remedies, each of which rights and remedies shall be
independent of the others and severally enforceable, and each of which is in
addition to, and not in lieu of, any other rights and remedies available to WCI
at law





                                       34
<PAGE>   36

or in equity:

                 (a)      SPECIFIC PERFORMANCE.  The right and remedy to have
         the Restrictive Covenants specifically enforced by any court of
         competent jurisdiction, it being agreed that any breach or threatened
         breach of the Restrictive Covenants would cause irreparable injury to
         WCI and that money damages would not provide an adequate remedy to
         WCI.  Accordingly, in addition to any other rights or remedies, WCI
         shall be entitled to injunctive relief to enforce the terms of the
         Restrictive Covenants and to restrain the Shareholders from any
         violation thereof.

                 (b)      ACCOUNTING.  The right and remedy to require the
         Shareholders to account for and pay over to WCI all compensation,
         profits, monies, accruals, increments or other benefits derived or
         received by the Shareholders as the result of any transactions
         constituting a breach of the Restrictive Covenants.

                 (c)      SEVERABILITY OF COVENANTS.  The Shareholders
         acknowledge and agree that the Restrictive Covenants are reasonable
         and valid in geographical and temporal scope and in all other
         respects.  If any court determines that any of the Restrictive
         Covenants, or any part thereof, is invalid or unenforceable, the
         remainder of the Restrictive Covenants shall not thereby be affected
         and shall be given full effect, without regard to the invalid
         portions.

                 (d)      BLUE-PENCILING.  If any court determines that any of
         the Restrictive Covenants, or any part thereof, is unenforceable
         because of the duration or geographic scope of such provision, such
         court shall reduce the duration or scope of such provision, as the
         case may be, to the extent necessary to render it enforceable and, in
         its reduced form, such provision shall then be enforced.

                 (e)      ENFORCEABILITY IN JURISDICTION.  WCI and the
         Shareholders intend to and hereby confer jurisdiction to enforce the
         Restrictive Covenants upon the courts of any jurisdiction within the
         geographic scope of the Restrictive Covenants.  If the courts of any
         one or more of such jurisdictions hold the Restrictive Covenants
         unenforceable by reason of the breadth of such scope or otherwise, it
         is the intention of WCI and the Shareholders that such determination
         not bar or in any way affect WCI's right to the relief provided above
         in the courts of any other jurisdiction within the geographic scope of
         the Restrictive Covenants as to breaches of such covenants in such
         other respective jurisdictions, such covenants as they relate to each
         jurisdiction being, for this purpose, severable into diverse and
         independent covenants.
