                                  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 March 1, 1998, the Company served
more than 120,000 commercial, industrial and residential customers in
Washington, California and Idaho. The Company owns six collection operations and
operates two 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 five solid waste services operations 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 Kansas, Montana,
Nebraska, Oklahoma, Oregon, South Dakota, Texas and Wyoming.
 
     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 the markets in which it operates.
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, which include the Company's current markets of Washington, California
and Idaho, 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.
 
     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 significant competitive
advantages as it pursues its growth 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
75,000 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 27,000
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
8,000 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 March 1, 1998, the
Fairmead Landfill was 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.
 
IDAHO ACQUISITIONS
 
     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 12,000
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.
 
     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 3,500 residential and commercial customers.
 
REVOLVING CREDIT FACILITY
 
     On January 30, 1998, the Company entered into a revolving credit facility
with BankBoston, N.A., which provides a borrowing capacity of $25.0 million. The
revolving credit facility was obtained primarily to fund acquisitions and to
refinance debt incurred in connection with the acquisition the Company completed
in September 1997. As of March 1, 1998, the aggregate
                                        4

outstanding principal indebtedness under the revolving credit facility was

(1) The combined financial data for the Company's predecessors for the years
    ended December 31, 1993, 1994, 1995 and 1996 do not purport to present the
    combined results of operations of the Company's predecessors in accordance
    with generally accepted accounting principles ("GAAP"). Instead, they
    represent merely a summation of statement of operations data and balance
    sheet data of the individual predecessor companies on an historical basis
    and exclude the effects of pro forma adjustments. This data will not be
    comparable to and may not be indicative of the Company's results of
    operations. In addition, the combined financial data of the predecessor
    operations may not necessarily be indicative of the financial position or
    results of operations that would have been realized had the predecessor
    companies been operated as stand-alone entities. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operations"
    and the audited financial statements of the Company and its predecessors.

                                  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. There can be no assurance that the Company
will be able to identify suitable acquisition candidates or, if such
                                        8
<PAGE>   10
 
candidates are identified, 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. The Company believes
that 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. 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. 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
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     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."
 
     Geographic Concentration. The Company's operations and customers are
located in Washington, California and Idaho, and the Company expects to focus
its operations on the Western U.S. for at least the foreseeable future. As of
March 1, 1998, approximately 68% 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."
 
     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
                                       10
<PAGE>   12
 
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."
 
     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 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
 
                                       11
<PAGE>   13
 
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. 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 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 March 1, 1998,
the estimated total remaining permitted disposal capacity of the Fairmead
Landfill
                                       12
<PAGE>   14
 
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."
 
     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,
                                       13
<PAGE>   15
 
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 29 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 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."
 
                                       14
<PAGE>   16
 
     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 5,799,998 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 or upon the exercise of currently outstanding stock options or
warrants. After this 180-day period expires, 5,749,998 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 50,000 of the currently outstanding shares of Common Stock will
become saleable in the public market ratably over three years, subject to the
restrictions of Rule 144. In addition, certain stockholders, who after the
closing of this offering will own approximately 5,799,998 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.
 
     The Company currently intends to file a shelf registration statement on
Form S-1 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
                                       15

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. See "Dilution."

                                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 approximately $18.0 million of the net proceeds
to repay all outstanding indebtedness under its credit facility with BankBoston,
N.A. 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
8.44% 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.
 
     The balance of the estimated net offering proceeds 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. The Company is not
currently a party to any letters of intent or similar agreements with respect to
any material pending acquisitions.
 
                                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 December 31, 1997, (i) the long-term
debt and capitalization of the Company on an historical basis, (ii) the pro
forma long-term debt and capitalization of the Company, giving effect to the
acquisitions of Waste Connections of Idaho, Inc. and Madera and the financing of
those acquisitions as if they had occurred on December 31, 1997 and (iii) such
pro forma 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 Series A Preferred Stock into 2,499,998 shares of
Common Stock 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 pro forma net tangible book value of the Company's Common Stock as of
December 31, 1997, was $(8.8) million, or $(1.52) per share. Pro forma 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), after giving effect to the
acquisitions of Waste Connections of Idaho, Inc. and Madera as if they had
occurred on December 31, 1997, divided by the total number of shares of Common
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 the assumed initial public offering price of
$11.00 per share (and after deduction of the underwriting discounts and
commissions and estimated offering expenses), the Company's pro forma net
tangible book value as of December 31, 1997, would have been approximately $10.4
million, or $1.33 per share of Common Stock. This represents an immediate
increase in pro forma net tangible book value of approximately $2.85 per share
to existing stockholders and an immediate dilution of pro forma net tangible
book value of $9.67 per share to new investors purchasing Common Stock in this
offering, as illustrated in the following table:

     As of March 1, 1998, the Company had outstanding stock options and warrants
exercisable for 2,308,800 shares of Common Stock at a weighted average exercise
price of $3.58 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 -- Stock Options and
Warrants."

         SELECTED HISTORICAL AND PRO FORMA FINANCIAL AND OPERATING DATA
 
     The following table presents selected historical and pro forma consolidated
statements of operations and balance sheet data of the Company and its
predecessors for the periods indicated.
 
     The combined selected financial information of the Company's predecessors
as of December 31, 1996, and for the nine months ended September 30, 1997, and
the years ended December 31, 1995 and 1996 has been derived from audited
financial statements included elsewhere in this Prospectus. The combined
selected financial information of the Company's predecessors as of December 31,
1995, and for the years ended December 31, 1993 and 1994 has been derived from
financial statements that have not been audited. In the opinion of the Company's
management, the unaudited financial data include all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of the
financial position and results of operations for the unaudited periods. The
combined financial statements of the Company's predecessors have been prepared
to present the financial position and results of operations of Browning-Ferris
Industries of Washington, Inc. and Fibres International, Inc., and each of their
respective predecessors, related to the assets acquired and liabilities assumed
by the Company under the terms of the Purchase and Sale Agreement dated
September 29, 1997, with BFI. The combined financial data for the Company's
predecessors for the years ended December 31, 1993, 1994, 1995 and 1996 do not
purport to present the combined results of operations of the Company's
predecessors in accordance with generally accepted accounting principles.
Instead, they represent merely a summation of statements of operations data and
balance sheet data of the individual predecessor companies on an historical
basis and exclude the effects of pro forma adjustments. This data will not be
comparable to and may not be indicative of the Company's future results of
operations. In addition, the combined financial data of the predecessor
operations may not necessarily be indicative of the financial position or
results of operations that would have been realized had the predecessor
companies been operated as stand-alone entities.
 
     The selected financial information for the Company as of December 31, 1997,
and for the period from inception (September 9, 1997) through December 31, 1997,
has been derived from audited financial statements included elsewhere in this
Prospectus. The selected financial information for Madera as of December 31,
1996 and 1997 and for the years ended December 31, 1995, 1996 and 1997 has been
derived from audited financial statements included elsewhere in this Prospectus.
 
     The selected pro forma financial information as of and for the year ended
December 31, 1997, gives effect to this offering and the Company's acquisitions
of Waste Connections of Idaho, Inc., Madera Disposal Systems, Inc. and the
Company's predecessors as of the dates and for the periods indicated, and has
been derived from unaudited pro forma financial statements included elsewhere in
this Prospectus. The pro forma financial information does not purport to
represent what the Company's results actually would have been if such events had
occurred at the dates indicated, nor does such information purport to project
the results of the Company for any future period. The Combined Company and
Predecessor statements of operations data for the year ended December 31, 1997,
reflect the summation of the operating results of the Company's predecessors for
the nine months ended September 30, 1997, with the operating results of the
Company for the period from inception (September 9, 1997) through December 31,
1997. The combined financial data do not purport to present the combined results
of operations of the Company and its predecessors in accordance with generally
accepted accounting principles. Instead, they represent merely a summation of
statements of operations data of the Company and its predecessors on an
historical basis and exclude the effects of pro forma adjustments. This data
will not be comparable to and may not be indicative of the Company's future
results of operations.
 
     The selected historical and pro forma financial information should be read
in conjunction with Management's Discussion and Analysis of Financial Condition
and Results of Operations, the audited Financial Statements and Notes thereto of
the Company and its predecessors, the audited Financial Statements and Notes
thereto of Madera, and the Unaudited Pro Forma Financial Statements and Notes
thereto included elsewhere in this Prospectus.

                    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 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 March 1, 1998, the Company served
more than 120,000 commercial, industrial and residential customers in
Washington, California and Idaho. The Company has six collection operations and
operates two transfer stations, one Subtitle D landfill and one recycling
facility.
 
     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
75,000 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 27,000
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 12,000
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 8,000 commercial, industrial and
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 3,500 residential and commercial customers.
 
     All of the foregoing acquisitions were accounted for under the purchase
method of accounting for business combinations. Accordingly, the results of
operations of these acquired businesses are included in the Company's Financial
Statements from the actual dates of acquisition.
 
     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
 
                                       24
<PAGE>   26
 
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 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 two 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
 
                                       25
<PAGE>   27
 
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 December 31, 1997, the Company had recorded
approximately $20,000 in such capitalized costs, all of which related to the
Madera acquisition. 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 December 31, 1997. 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.
 
RESULTS OF OPERATIONS
 
     The combined selected financial information of the Company's predecessors
for the years ended 1995 and 1996 and the combined results of operations of the
Company for the three months ended December 31, 1997 and its predecessors for
the nine months ended September 30, 1997 has been derived from audited financial
statements included in this prospectus. Such combined financial information
represents merely a summation of statement of operations data of the Company and
its predecessors on an historical basis. The information excludes the effects of
pro forma adjustments. The statements therefore do not fully reflect (i)
potential cost savings, synergies and efficiencies that may be achieved through
the integration of the businesses and operations of the Company's predecessors;
and (ii) expenses that the Company may incur as it seeks to increase the
efficiency of the predecessor operations.
 
Waste Connections, Inc. and Predecessors 1997 vs. Predecessors 1996
 
     Revenue.  Total revenues increased $2.2 million, or 9.9%, to $24.4 million
in 1997 from $22.2 million in 1996. This increase was primarily attributable to:
(i) increased volumes resulting from new contracts and existing G certificates,
franchise agreements and municipal contracts and (ii) to a lesser extent,
increased pricing for collection and disposal services.
 
     Cost of Operations.  Total cost of operations increased $1.9 million to
$19.5 million in 1997 from $17.6 million in 1996. The principal reason for the
increase was the addition of new customers and contracts during the year. Cost
of operations as a percent of revenue increased to 79.9% in 1997 from 79.4% in
1996. The percentage increase was the result of proportionately more growth in
lower-margin services and an increase in waste stream processing and disposal
costs.
 
     SG&A.  SG&A expenses decreased $147,000 to $3.6 million in 1997 from $3.8
million in 1996. As a percentage of revenues, SG&A decreased to 14.9% from 17.0%
in 1996 due to improved economies of scale related to the revenue increase
discussed above.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased approximately $151,000 to $1.4 million in 1997 from $1.3 million in
1996. Depreciation and
                                       26
<PAGE>   28
 
amortization increased as a percentage of revenues, to 5.9% from 5.8% in 1996.
This increase was principally due to the revaluation of assets associated with
the BFI purchase of The Disposal Group in 1996 and the Company's purchase of the
BFI assets in 1997.
 
     Interest Expense.  Interest expense increased $819,000 to $1.1 million in
1997 from $237,000 in 1996. The principal reason for the increase was an
increase in financing fees and a higher level of average annual outstanding
indebtedness as a result of the purchase of the BFI operations in September
1997. In anticipation of the refinancing of all indebtedness, the Company
amortized loan fees and warrant costs associated with the financing of the
purchase of the BFI operations in the fourth quarter 1997. Interest as a
percentage of revenues increased to 4.3% in 1997 from 1.1% in 1996.
 
Predecessors 1996 vs. Predecessors 1995
 
     Revenue. Total revenues decreased $5.4 million, or 19.7%, to $ 22.2 million
in 1996 from $27.6 million in 1995. The decrease was primarily attributable to
the expiration of a residential waste collection contract and to a lessor
extent, pricing associated with recycling material sales.
 
     Cost of Operations. Total cost of operations decreased $5.0 million to
$17.6 million in 1996 from $22.6 million in 1995. The principal reason for the
decrease is related to the revenue decrease discussed above. Cost of operations
as a percentage of revenues decreased to 79.4% in 1996 from 81.8% in 1995. This
percentage decrease was the result of the loss of lower-margin services
associated with the expired residential contract.
 
     SG&A. SG&A expenses decreased approximately $432,000 to $3.8 million in
1996 from $4.2 million in 1995. As a percentage of revenues, SG&A increased to
17.0% from 15.2% in 1995 due to reduced economies of scale in the Company's
collection operations associated with the expired residential contract.
 
     Depreciation and amortization. Depreciation and Amortization expense
decreased approximately $131,000 to $1.3 million in 1996 compared to $1.4
million in 1995. Depreciation and amortization increased as percentage of
revenues to 5.8% from 5.1% in 1995, primarily as a result of lower revenue
associated with the expired residential contract.
 
     Interest Expense. Interest expense decreased $132,000 to $237,000 in 1996
from $369,000 in 1995. Interest as a percentage of revenues decreased to 1.1% in
1996 from 1.3% in 1995.
 
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 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 volume increases 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%.
 
                                       27
<PAGE>   29
 
     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 pricing associated with recycling material sales.
 
     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. 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. At
March 1, 1998, an aggregate of approximately $17.0 million was outstanding under
the revolving line of credit. The Company believes that, through a combination
of internally generated funds, its credit facility and the net proceeds of this
offering, it will be able to satisfy its anticipated working capital needs for
at least the next 12 months.
 
     Net cash provided by operations for the year ended December 31, 1997 was
$794,000, compared to $2.0 million for the same period in 1996. The decrease was
primarily due to the favorable settlement of a lawsuit in the amount of $2.6
million in 1996.
 
     Net cash used in investing activities for the year ended December 31, 1997
was $11.9 million compared to $139,000 for the same period in 1996. The increase
was primarily due to the payment of $11.5 million for the acquisition by the
Company of the predecessor companies.
 
     Net cash provided by financing activities for the year ended December 31,
1997 was $11.9 million compared to $318,000 for the same period in 1996. The
increase was primarily due to
 
                                       28
<PAGE>   30
 
borrowings under the Company's credit facility then in effect of $5.5 million
and proceeds from the sale of redeemable convertible preferred stock of $7.0
million. At December 31, 1997, the Company had approximately $6.8 million of
long-term debt outstanding.
 
     The Company recorded an income tax benefit of $186,000 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.
 
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 March 1, 1998, the Company served
more than 120,000 commercial, industrial and residential customers in
Washington, California and Idaho. The Company owns six collection operations and
operates two 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 five solid waste services operations 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, South Dakota, Texas and Wyoming.
 
     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.
 
                                       30
<PAGE>   32
 
     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 Company believes the industry remains
primarily regional in nature and highly fragmented. Based on published industry
sources, the Company believes that 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 and Idaho, and is assessing potential acquisitions of
solid waste services operations in Kansas, Montana, Nebraska, Oklahoma, Oregon,
South Dakota, Texas and Wyoming.
 
     The Company believes that numerous "tuck-in" acquisition opportunities
exist within its current and targeted market areas. For example, the Company
believes that more than 300 independent entities 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
                                       32
<PAGE>   34
 
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 two 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 and Idaho 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
                                       33
<PAGE>   35
 
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.
 
SERVICES
 
  Commercial, Industrial and Residential Waste Services
 
     The Company serves more than 120,000 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 60,000 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
 
                                       34
<PAGE>   36
 
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 which receive, compact, and
transfer solid waste to larger Company-owned 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 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 March 1, 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
                                       35
<PAGE>   37
 
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 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 seven operating locations
serving four 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
 
                                       36
<PAGE>   38
 
to have their solid waste collection overseen by the WUTC. G certificates
typically 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 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, 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, fair and equitable rates to customers of 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 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 14.0% of the Company's
revenues during the three months ended December 31, 1997. Under this contract,
the Company serves more than 34,000 residential and commercial customers. There
are approximately nine years remaining under that contract. No

COMPETITION
 
     The solid waste services industry is highly competitive and fragmented and
requires substantial labor and capital resources. The industry 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. 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 grant
the Company perpetual and generally exclusive collection rights in certain
areas. The Company believes that it 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.
 
                                       38

     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 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. For the three-month period ended December 31, 1997, the
Company believes it did not 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,
                                       39
<PAGE>   41
 
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 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.
 
                                       40
<PAGE>   42
 
  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.
 
                                       41
<PAGE>   43
 
     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,
OSHA, 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").
The WUTC also sets rates for 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 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 believes that all of its 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 landfills. The Company has not
experienced difficulty in obtaining performance bonds or letters of credit for
its current operations. At March 1, 1998, the Company had provided customers and
various
                                       42
<PAGE>   44
 
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. 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.
 
     At March 1, 1998, the Company owned or leased approximately 150 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 52,000 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 believes that its vehicles, equipment
and operating properties are well maintained and adequate for its current
operations. 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 March 1, 1998, the Company employed approximately 240 full-time
employees, including approximately 25 persons classified as professionals or
managers, approximately 190 employees involved in collection, transfer, disposal
and recycling operations, and approximately 25 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 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.
 
                                       43
<PAGE>   45
 
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

(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.

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, 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 March 1, 1998, the Company had granted options to purchase
857,800 shares of Common Stock at a weighted average exercise price of $5.23 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.

     On February 1, 1998, Steven F. Bouck was granted options to purchase
230,000 shares of Common Stock, pursuant to his employment agreement with the
Company. These options include an option to purchase 100,000 shares at an
exercise price of $2.80 per share, of which one-third is exercisable on each of
October 1, 1998, October 1, 1999, and October 1, 2000. Of Mr. Bouck's remaining
options, an option to purchase 50,000 shares has an exercise price of $9.50 per
share, and an option to purchase 50,000 shares has an exercise price of $12.50
per share; one-third of each of these options vests on each of October 1, 1998,
October 1, 1999, and October 1, 2000. Mr. Bouck also received an option to
purchase 30,000 shares of Common Stock at an exercise price of $2.80 per share,
which vests ratably on October 1, 1998, 1999 and 2000 if certain events occur.
On February 1, 1998, Mr. Bouck was granted an immediately exercisable warrant to
purchase 50,000 shares of Common Stock at an exercise price of $2.80 per share.
 
     On February 23, 1998, Eugene V. Dupreau and Charles B. Youngclaus were
granted warrants in connection with the Company's acquisition of Madera. See
"Purchase of Madera Disposal Systems, Inc." below.
 
PURCHASE OF WASTE CONNECTIONS OF IDAHO, INC.
 
     On January 30, 1998, the Company purchased all of the outstanding stock of
Waste Connections of Idaho, Inc. ("Waste Connections Idaho") from Ronald J.
Mittelstaedt, J. Bradford Bishop and James N. Cutler, Jr., the sole shareholders
of Waste Connections Idaho. The aggregate purchase price was $3,000, which was
the aggregate price paid initially by Messrs. Mittelstaedt, Bishop and Cutler
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.
 
PURCHASE OF MADERA DISPOSAL SYSTEMS, INC.
 
     Eugene V. Dupreau was President and a 16.7% shareholder of Madera Disposal
Systems, Inc. before it was acquired by the Company on February 23, 1998.
Charles B. Youngclaus was Chief Operating Officer and a 16.7% shareholder of
Madera before it was acquired by the Company. For their shares of Madera's
common stock, each of Messrs. Dupreau and Youngclaus received $630,662 in cash,
333,333 shares of the Company's Common Stock and warrants to purchase 66,667
shares of the Company's Common Stock at an exercise price of $4.00 per share.
Each of Messrs. Dupreau and Youngclaus has been engaged by the Company as Vice
President -- Madera. Mr. Dupreau was appointed a director of the Company,
effective February 23, 1998.
 
     In addition, the Company is required to pay contingent consideration to
certain former Madera shareholders, subject to their involvement in the events
that give rise to the consideration, if the Company enters into certain
specified business transactions by February 3, 2001. These shareholders may
include Messrs. Dupreau and Youngclaus.
 
OTHER TRANSACTIONS.
 
     The Company has entered into certain transactions with Continental Paper,
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 3,300,000 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 7,799,998 shares of Common Stock outstanding (8,099,998 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 director, 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
                                       56
<PAGE>   58
 
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.
 
                                       57
<PAGE>   59
 
     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

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

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have 7,799,998 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, 7,749,998 of the
currently outstanding shares will be eligible for resale in the public market
under Rule 144 promulgated under the Securities Act, and an additional 50,000 of
the currently outstanding shares will become eligible for resale in the public
market ratably over three years, 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 or upon exercise
of currently outstanding stock options or warrants, 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 (78,000 shares
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
 
                                       59
<PAGE>   61
 
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 on Form S-1 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."

</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.
 
                                       61
<PAGE>   63
 
     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 or upon exercise
of currently outstanding stock options or warrants, 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.

                      INTRODUCTION TO UNAUDITED PRO FORMA
                       CONSOLIDATED FINANCIAL STATEMENTS
 
     The following Unaudited Pro Forma Consolidated Balance Sheet as of December
31, 1997, and the Unaudited Pro Forma Consolidated Statement of Operations for
the year ended December 31, 1997, give effect to this offering and the business
combinations involving Waste Connections, Inc., (the "Company"), its
predecessors, Waste Connections of Idaho, Inc. ("WCII") 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 and the Company's acquisitions of WCII
and Madera had occurred on December 31, 1997, and the Pro Forma Consolidated
Statements of Operations is presented as if this offering and the Company's
acquisitions of its predecessors and Madera had occurred as of January 1, 1997
and its acquisition of WCII occurred on September 30, 1997, the date of
inception of WCII.
 
     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, the predecessors, Madera
and WCII 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.

     ASSUMPTIONS. The unaudited pro forma consolidated statements of operations

     (c) To adjust facilities lease expense.
 
     (d) To reduce franchise fees based upon renegotiated amounts.

     (g) To increase depreciation for the increase of property, plant and
         equipment's carrying value to fair value.

         expense on the debt obligations incurred by the Company in connection
         with the acquisitions of the predecessors.
 
     (j) To record the estimated 40% tax provision associated with the pro forma
         adjustments.
 
     (k) To record income tax benefit for the net operating loss incurred by the
         predecessors for the nine months ended September 30, 1997.

         Cleaning Division of Madera which ceased operating in July 1997.

     (q) To record interest expense on the long-term debt obligation incurred by
         the Company in connection with the Madera acquisition.
 
     (r) To eliminate interest expense, as the offering proceeds will be used to

     (s) To record income taxes for Madera, which was a subchapter S corporation
         prior to its acquisition by the Company.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1997
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
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 noninterest-bearing 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. Accordingly, the historical financial statements for the
predecessors during these periods do not include interest expenses directly
related to predecessor intercompany accounts with BFI. 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.

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
     Due to the manner in which BFI intercompany transactions were recorded, 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 $1,912 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:

     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.
 
  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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1997
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
  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 $2,484
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 $1.09 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.
 
     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.
 
  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, based on current
incremental borrowing rates for similar types of borrowing arrangements.

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
  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, $275 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.

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
  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 loss per share is computed by dividing the net 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.
 
  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 for the
Acquisitions is as follows:

  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. 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 will be 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 $9,869 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 (the "Stock"), warrants to purchase 200,000 shares of the
Company's common stock at $4.00 per share (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 will be 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 are estimated to be approximately $12,819 and $9,163, respectively.
 
  Predecessor Acquisitions
 
     As described in Note 1, BFI acquired for cash and debt Fibres
International, Inc. on November 30, 1995 and The Disposal Group Combined on July
31, 1996 in transactions that were accounted for as purchases. Accordingly, the
respective purchase prices were allocated to the fair values of the assets
acquired and liabilities assumed. The following presents purchase price

</TABLE>
 
     Related to the Acquisitions (Note 2), the Company entered into a
non-competition agreement with BFI. 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 ($150) is
being amortized on a straight-line method over the term of the agreement (five
years). Accumulated amortization amounted to $8 as of December 31, 1997.
 
5. LINE OF CREDIT
 
     On September 30, 1997, the Company obtained a revolving line of credit (the
"Line") from a bank (the "Bank"). The maximum amount available under the terms
of the Line was $2,000 and borrowings bore interest based on the prime rate plus
1.5% (aggregating 10.0% at December 31, 1997). Interest was payable monthly and
the Line was to expire on September 29, 1998. Borrowings under the Line were
secured by substantially all of the Company's assets and were subordinate to the
notes payable to BFI (Note 6) with respect to certain specified assets. The Line
was personally guaranteed by certain officers and stockholders of the Company
(Note 9). As of December 31, 1997, $600 was outstanding under the Line.
 
     Management used borrowings from a new credit facility obtained in January
1998 (Note 12) to pay off amounts outstanding under the Line, and as such, these
amounts have been included in long-term debt as of December 31, 1997.

  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, 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
 
                                      F-26

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
December 31, 1997 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, 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, no options to purchase common stock were
exercisable under the Option Plan. In addition, as of December 31, 1997, options
for 671,500 shares 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 10 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 $(2,870) and
$(1.48) per share, respectively.
 
  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 $216 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 $1.09 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 $59 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 $1.09 per share and expected
lives of 3 years. The value assigned to

     In December 1997, the Company issued to consultants warrants to purchase

5,000 shares of common stock had exercise prices of $5.00 per share and $2.80
per share, respectively.
 
  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.
 
     Subsequent to December 31, 1997 and through March 6, 1998, the Company had
the following equity related transactions:
 
     -  In connection with the Madera acquisition (Note 2) the Company issued
        1,000,000 shares of common stock and issued warrants to purchase 200,000
        shares of common stock.
 
     -  Options to purchase an aggregate of 329,300 shares of common stock at
        exercise prices ranging from $2.80 to $12.50 per share, which includes
        30,000 options to purchase common stock at $2.80 per share which vest
        ratably over 3 years if certain events occur, and warrants to purchase
        an aggregate of 195,000 shares of common stock at exercise prices
        ranging from $2.80 to $5.00 per share were granted.
 
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

 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.

                                 (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:

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
 
     Madera leases its facilities and certain equipment under cancelable
operating leases for periods of one year or less. Rent expense under all
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. At 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 stations, or alleging environmental damage
or violations of the permits and 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.
 
5. RELATED PARTY TRANSACTIONS
 
     Madera performs repair services on equipment owned and operated by
shareholders of Madera. Revenues relating to these activities were $41, $60 and
$51 for the years ended December 31, 1995, 1996 and 1997, respectively. As of
December 31, 1996 and 1997, Madera has receivables of $100 and $113,
respectively, relating to these activities.
 
6. 401(K) PLAN
 
     Madera has a voluntary savings and investment plan (the "401(k) Plan"). The
401(k) Plan is available to all eligible employees of Madera. Under the 401(k)
Plan Madera is required to match 100% of employees' contributions up to a
maximum of 3% of the employees' wages. During the years ended December 31, 1995,
1996 and 1997, Madera's 401(k) Plan expenses were approximately $78, $107 and
$108, respectively.

</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 suite 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>   111
 
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.
 
                                      II-2
<PAGE>   112
 
     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

     directors of the Company. Such sales were made in accordance with
     Regulation D promulgated under the Securities Act.
 
          2. In September 1997, the Company issued warrants to purchase 200,000

     entered into by the Company. Such warrants were issued pursuant to
     Regulation D under the Securities Act.
 
        3. In October and November 1997, the Company issued options to purchase
     428,500 shares of Common Stock to employees of the Company. Such options
     have exercise prices ranging from $2.80 per share to $10.50 per share and a
     weighted average exercise price of $5.42 per share. Some of such options
     were issued pursuant to Regulation D under the Securities Act and others
     were issued pursuant to Rule 701 under the Securities Act.
 
          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
     purchase 5,000 shares of Common Stock to a fourth consultant, with an
     exercise price of $2.80 per share. Such warrants were issued pursuant to
     Rule 701 under the Securities Act.
 
          6. In January 1998, the Company issued warrants to purchase 140,000
     shares of Common Stock to BankBoston, N.A., at an exercise price of $2.80
     per share, in connection with the Company's credit facility with
     BankBoston, N.A. Such warrants were issued pursuant to Regulation D under
     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

     B. FINANCIAL STATEMENT SCHEDULE.
 
     The following financial statement schedule is filed herewith and made a
part hereof:
 
        Schedule II -- Valuation and Qualifying Accounts
 
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.

<PAGE>   2


                                    ARTICLE V

               A. The Corporation is authorized to issue two classes of stock to
be designated, respectively, "Common Stock" and "Preferred Stock". The amount of
the total authorized capital stock of the Corporation is 60,000,000 shares,
divided into (a) 50,000,000 shares of Common Stock, par value $0.01 per share,
and (b) 10,000,000 shares of Preferred Stock, par value $0.01 per share.

               B. The Preferred Stock may be issued from time to time in one or
more series. Subject to the restrictions prescribed by law, the Board of
Directors is authorized to fix by resolution or resolutions the number of shares
of any series of Preferred Stock and to determine or alter the rights,
preferences, privileges and restrictions granted to or imposed upon any wholly
unissued series of Preferred Stock and, within the limits and restrictions
stated in any resolution or resolutions of the Board of Directors originally
fixing the number of shares constituting any series of Preferred Stock, to
increase (but not above the total number of authorized shares of Preferred
Stock) or decrease (but not below the number of shares of any such series then
outstanding) the number of shares of any such series subsequent to the issue of
shares of that series. Different series of Preferred Stock shall not be
construed to constitute different classes of shares for the purposes of voting
by classes unless expressly provided.

               The authority of the Board of Directors with respect to each
series of Preferred Stock shall include, but not be limited to, determination of
the following: (a) the number of shares constituting that series and the
distinctive designation of that series; (b) the dividend rate on the shares of
that series, whether dividends shall be cumulative, and if so, from which date
or dates, and the relative rights of priority, if any, of payment of dividends
on shares of that series; (c) whether that series shall have voting rights in
addition to the voting rights provided by law, and if so, the terms of such
voting rights; (d) whether that series shall have conversion privileges, and if
so, the terms and conditions of such privileges, including provision for
adjustment of the conversion rate in such events as the Board of Directors shall
determine; (e) whether or not the shares of that series shall be redeemable, and
if so, the terms and conditions of such redemption, including the date or dates
upon or after which they shall be redeemable, and the amount per share payable
in case of redemption, which amount may vary under different conditions and at
different redemption dates; (f) whether that series shall have a sinking fund
for the redemption or purchase of shares of that series, and if so, the terms
and the amount of such sinking funds; (g) the rights of the shares of that
series in the event of voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, and the relative rights of priority, if any, of
payment of shares of that series; and (h) any other relative rights, preferences
and limitations of that series.

               C. 2,500,000 shares of Preferred Stock are designated the Series
A Preferred Stock, $0.01 par value (the "Series A Preferred Stock"), of this
Corporation, with the following powers, designations, preferences and other
special rights:

        1. Dividend Provisions. Subject to the rights of series of Preferred
Stock which may from time to time come into existence, the holders of shares of
Series A Preferred Stock shall be entitled to receive dividends, out of any
assets legally available therefor, prior and in preference to any declaration or
payment of any dividend (payable other than in Common Stock



                                        2

<PAGE>   3

or other securities and rights convertible into or entitling the holder thereof
to receive, directly or indirectly, additional shares of Common Stock of this
Corporation) on the Common Stock of this Corporation, at the rate of $0.098 per
share of Series A Preferred Stock (as adjusted for any stock dividends, splits
or combinations with respect to such shares) per annum, payable quarterly when,
as and if declared by the Board of Directors on the last day of each calendar
quarter beginning December 31, 1997. Such dividends shall accrue on each share
from September 30, 1997, and shall accrue from day to day, whether or not earned
or declared. Such dividends shall be cumulative so that, except as provided
below, if such dividends in respect of any previous or current annual dividend
period, at the annual rate specified above, shall not have been paid, the
deficiency shall first be fully paid before any dividend or other distribution
shall be paid on or declared and set apart for the Common Stock. Any
accumulation of dividends on the Series A Preferred Stock shall not bear
interest. Cumulative dividends with respect to a share of Series A Preferred
Stock which are accrued, payable and/or in arrears shall, upon conversion of
such share to Common Stock, subject to the rights of series of Preferred Stock
which may from time to time come into existence, be converted into additional
shares of Common Stock on the same terms as Series A Preferred Stock is
convertible into Common Stock, based upon the Conversion Price (as defined
below) at the time of such conversion.

        Unless full dividends on the Series A Preferred Stock for all past
dividend periods and the then current dividend period shall have been paid or
declared and a sum sufficient for the payment thereof set apart: (A) no dividend
whatsoever (other than a dividend payable solely in Common Stock or other
securities and rights convertible into or entitling the holder thereof to
receive, directly or indirectly, additional shares of Common Stock) shall be
paid or declared, and no distribution shall be made, on any Common Stock and (B)
no shares of Common Stock shall be purchased, redeemed, or acquired by this
Corporation and no funds shall be paid into or set aside or made available for a
sinking fund for the purchase, redemption, or acquisition thereof; provided,
however, that this restriction shall not apply to the repurchase of shares of
Common Stock held by employees, officers, directors, consultants or other
persons performing services for this Corporation or any wholly-owned subsidiary
(including, but not by way of limitation, distributors and sales
representatives) that are subject to restrictive stock purchase agreements under
which this Corporation has the option to repurchase such shares upon the
occurrence of certain events, such as the termination of employment.

        2.     Liquidation Preference.

               a. In the event of any liquidation, dissolution or winding up of
this Corporation, either voluntary or involuntary (a "Liquidation"), subject to
the rights of series of Preferred Stock that may from time to time come into
existence, the holders of Series A Preferred Stock shall be entitled to receive,
prior and in preference to any distribution of any of the assets of this
Corporation to the holders of Common Stock by reason of their ownership thereof,
an amount per share equal to the sum of (i) $2.80 for each outstanding share of
Series A Preferred Stock (the "Original Series A Issue Price"), (ii) an amount
equal to accrued but unpaid dividends on such share ("Accrued Dividends"), and
(iii) if a Liquidation occurs prior to October 1, 1998, $1.40 for each
outstanding share of Series A Preferred Stock or, if a Liquidation occurs on or
after October 1, 1998, an amount necessary to provide the holder of such share
an internal rate of return of 50% (such amounts in clauses (ii) and (iii) being
referred



                                        3

<PAGE>   4

to herein as the "Premium"). If upon the occurrence of such event, the assets
and funds thus distributed among the holders of the Series A Preferred Stock
shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then, subject to the rights of series of
Preferred Stock that may from time to time come into existence, the entire
assets and funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred Stock in
proportion to the amount of such stock owned by each such holder.

               b. Upon the completion of the distribution required by
subparagraph (a) of this Section C.2 and any other distribution that may be
required with respect to series of Preferred Stock that may from time to time
come into existence, if assets remain in this Corporation, the holders of the
Common Stock and the Series A Preferred Stock of this Corporation, shall receive
all of the remaining assets of this Corporation as if the Series A Preferred
Stock had been converted to Common Stock immediately prior to the distribution
of such remaining assets.

               c. For purposes of this Section C.2, a Liquidation of this
Corporation shall be deemed to be occasioned by, or to include, (A) the
acquisition of this Corporation by another entity by means of any transaction or
series of related transactions (including, without limitation, any
reorganization, merger or consolidation but, excluding any merger effected
exclusively for the purpose of changing the domicile of this Corporation); (B) a
sale of all or substantially all of the assets of this Corporation; or (C) sale
of the outstanding stock of this Corporation by its stockholders unless this
Corporation's stockholders of record as constituted immediately prior to such
acquisition or sale will, immediately after such acquisition or sale (by virtue
of securities issued as consideration for this Corporation's acquisition or sale
or otherwise) hold at least 50% of the voting power of the surviving or
acquiring entity.

                      (1)    In any of such events, if the consideration
received by this Corporation is other than cash, its value will be deemed its
fair market value. Any securities shall be valued as follows:

                             (a)    Securities not subject to investment letter
or other similar restrictions on free marketability:

                                    i)      If traded on a securities exchange
or through The NASDAQ Stock Market, Inc., the value shall be deemed to be the
average of the closing prices of the securities on such exchange over the
thirty-day period ending three (3) days prior to the closing;

                                    ii)     If actively traded over-the-counter,
the value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the thirty-day period ending three (3) days prior
to the closing; and

                                    iii) If there is no active public market,
the value shall be the fair market value thereof, as mutually determined by this
Corporation and the holders of



                                        4

<PAGE>   5

at least a majority of the voting power of the then outstanding shares of Common
Stock and of such Preferred Stock.

                             (b) The method of valuation of securities subject
to investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a stockholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (a) (i), (ii) or (iii) to reflect the approximate
fair market value thereof, as mutually determined by this Corporation and the
holders of at least a majority of the voting power of each of all then
outstanding shares of Common Stock and of such Preferred Stock.

                      (2) In the event the requirements of this subsection
C.2(c) are not complied with, this Corporation shall forthwith either:

                             (a)    cause such closing to be postponed until
such time as the requirements of this Section C.2 have been complied with; or

                             (b) cancel such transaction, in which event the
rights, preferences and privileges of the holders of the Series A Preferred
Stock shall revert to and be the same as such rights, preferences and privileges
existing immediately prior to the date of the first notice referred to in
subsection C.2.c.(3) hereof.

                      (3) This Corporation shall give each holder of record of
Series A Preferred Stock written notice of such impending transaction not later
than twenty (20) days prior to the stockholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section C.2, and this Corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after this Corporation has given the first notice
provided for herein or sooner than ten (10) days after this Corporation has
given notice of any material changes provided for herein; provided, however,
that such periods may be shortened upon the written consent of the holders of
Preferred Stock that are entitled to such notice rights or similar notice rights
and that represent at least a majority of the voting power of all then
outstanding shares of such Preferred Stock.

        3.     Redemption.

               a. Subject to the rights of series of Preferred Stock which may
from time to time come into existence, to statutory limitation on the right of
this Corporation to repurchase its own stock and to any limitation imposed by
this Corporation's bank or other institutional lenders to repurchase or redeem
shares of its stock, at any time after April 1, 1999 and before October 1, 1999,
at the individual option of each holder of shares of Series A Preferred Stock
this Corporation shall redeem, from any source of funds legally available
therefor, within 30 days after the date this Corporation receives a request for
redemption, (each a "Series A Redemption Date"), the number of shares of Series
A Preferred Stock held by such holder that



                                        5

<PAGE>   6

is specified in a request for redemption delivered to this Corporation by the
holder on or prior to October 1, 1999, by paying in cash therefor: (i) $4.20 per
share of Series A Preferred Stock (as adjusted for any stock dividends,
combinations or splits with respect to such shares) plus (ii) an amount equal to
Accrued Dividends on such share (the "Series A Redemption Price").

               b. As used herein and in subsection C.3.c below, the term
"Redemption Date" shall refer to each "Series A Redemption Date" and the term
"Redemption Price" shall refer to each "Series A Redemption Price." Subject to
the rights of series of Preferred Stock which may from time to time come into
existence, at least ten (10) but no more than twenty (20) days prior to the
Redemption Date, written notice shall be mailed, first class postage prepaid, to
each holder of record (at the close of business on the business day next
preceding the day on which notice is given) of the Series A Preferred Stock to
be redeemed, at the address last shown on the records of this Corporation for
such holder, confirming the number of shares to be redeemed from such holder,
the Redemption Date, the Redemption Price, the place at which payment may be
obtained and calling upon such holder to surrender to this Corporation, in the
manner and at the place designated, his, her or its certificate or certificates
representing the shares to be redeemed (the "Redemption Notice"). Except as
provided in subsection C.3.c on or after the Redemption Date, each holder of
Series A Preferred Stock to be redeemed shall surrender to this Corporation the
certificate or certificates representing such shares, in the manner and at the
place designated in the Redemption Notice, and thereupon the Redemption Price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be cancelled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

               c. From and after the Redemption Date, unless there shall have
been a default in payment of the Redemption Price, all rights of the holders of
shares of Series A Preferred Stock designated for redemption in the Redemption
Notice as holders of Series A Preferred Stock (except the right to receive the
Redemption Price without interest upon surrender of their certificate or
certificates) shall cease with respect to such shares, and such shares shall not
thereafter be transferred on the books of this Corporation or be deemed to be
outstanding for any purpose whatsoever. Subject to the rights of series of
Preferred Stock which may from time to time come into existence, if the funds of
this Corporation legally available for redemption of shares of Series A
Preferred Stock on any Redemption Date are insufficient to redeem the total
number of shares of Series A Preferred Stock to be redeemed on such date, this
Corporation shall use reasonable efforts to sell additional shares of capital
stock but this Corporation shall be under no obligation to incur debt or sell
assets to effect any such redemption. Those funds which are legally available
will be used to redeem the maximum possible number of such shares ratably among
the holders of such shares to be redeemed based upon their holdings of Series A
Preferred Stock. The shares of Series A Preferred Stock not redeemed shall
remain outstanding and entitled to all the rights and preferences provided
herein. Subject to the rights of series of Preferred Stock which may from time
to time come into existence, at any time thereafter when additional funds of
this Corporation are legally available for the redemption of shares of Series A
Preferred Stock, such funds will immediately be used to redeem the balance of
the shares which this Corporation has become obliged to redeem on any Redemption
Date but which it has not redeemed.

        4. Conversion. The holders of the Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               a. Right to Convert. Each share of Series A Preferred Stock shall
be convertible, at the option of the holder thereof, at any time after the date
of issuance of such share at the office of this Corporation or any transfer
agent for such stock, into: (i) such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing the Original Series A Issue
Price by the Conversion Price applicable to such share, determined as hereafter
provided, in effect on the date the certificate is surrendered for conversion;
plus (ii) such number of fully paid and nonassessable shares of Common Stock as
is determined by dividing the Accrued Dividends attributable to such share of
Series A Preferred Stock as of such date by the Conversion Price as of such
date. The initial Conversion Price per share for shares of Series A Preferred
Stock shall be the Original Series A Issue Price; provided, however, that the
Conversion Price for the Series A Preferred Stock shall be subject to adjustment
as set forth in subsection C.4.d.

               b. Automatic Conversion. Each share of Series A Preferred Stock
and any Accrued Dividends attributable to such share of Series A Preferred Stock
shall automatically be converted into shares of Common Stock at the Conversion
Price at the time in effect for such Series A Preferred Stock immediately upon
the earlier of (i) except as provided below in subsection C.4.c, this
Corporation's sale of its Common Stock in a firm commitment underwritten public
offering pursuant to a registration statement on Form S-1 under the Securities
Act of 1933, as amended, the public offering price of which was not less than
$5.00 per share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalization) and $5,000,000 in the aggregate (an "IPO") or (ii) the date
specified by written consent or agreement of the holders of a majority of the
then outstanding shares of Series A Preferred Stock.

               c. Mechanics of Conversion. Before any holder of Series A
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, he shall surrender the certificate or certificates therefor, duly
endorsed, at the office of this Corporation or of any transfer agent for the
Series A Preferred Stock, and shall give written notice to this Corporation at
its principal corporate office, of the election to convert the same and shall
state therein the name or names in which the certificate or certificates for
shares of Common Stock are to be issued. This Corporation shall, as soon as
practicable thereafter, issue and deliver at such office to such holder of
Series A Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series A Preferred Stock to be converted, and the
person or persons entitled to receive the shares of Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock as of such date. If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Securities Act of 1933, the conversion may, at the option of any holder
tendering Series A Preferred Stock for conversion, be conditioned upon the
closing with the underwriters of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive the Common Stock upon
conversion



                                        7

<PAGE>   8



of the Series A Preferred Stock shall not be deemed to have converted such
Series A Preferred Stock until immediately prior to the closing of such sale of
securities.

               d. Conversion Price Adjustments of Preferred Stock for Certain
Dilutive Issuances, Splits and Combinations. The Conversion Price of the Series
A Preferred Stock shall be subject to adjustment from time to time as follows:

                      (1) (a) If this Corporation shall issue, after the date
upon which any shares of Series A Preferred Stock were first issued (the
"Purchase Date" with respect to such series), any Additional Stock (as defined
below in Section C.4.d.(2)) without consideration or for a consideration per
share less than the Conversion Price for such series in effect immediately prior
to the issuance of such Additional Stock, the Conversion Price for such series
in effect immediately prior to each such issuance shall forthwith (except as
otherwise provided in this paragraph (1)) be adjusted to a price determined by
multiplying such Conversion Price by a fraction, the numerator of which shall be
the number of shares of Common Stock outstanding immediately prior to such
issuance (not including shares excluded from the definition of Additional Stock
by Section C.4.d.(2)(b)) plus the number of shares of Common Stock that the
aggregate consideration received by this Corporation for such issuance would
purchase at such Conversion Price; and the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issuance
(not including shares excluded from the definition of Additional Stock by
subsection C.4.d.(2)(b)) plus the number of shares of such Additional Stock.

                             (b)    No adjustment of the Conversion Price for
the Series A Preferred Stock shall be made in an amount less than one cent per
share, provided that any adjustments which are not required to be made by reason
of this sentence shall be carried forward and shall be either taken into account
in any subsequent adjustment made prior to 3 years from the date of the event
giving rise to the adjustment being carried forward, or shall be made at the end
of 3 years from the date of the event giving rise to the adjustment being
carried forward. Except to the limited extent provided for in subsections
C.4.d.(1)(e)(iii) and C.4.d.(1)(e)(iv), no adjustment of such Conversion Price
pursuant to this subsection C.4.d.(1)(b) shall have the effect of increasing the
Conversion Price above the Conversion Price in effect immediately prior to such
adjustment.

                             (c) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
before deducting any reasonable discounts, commissions or other expenses
allowed, paid or incurred by this Corporation for any underwriting or otherwise
in connection with the issuance and sale thereof.

                             (d)    In the case of the issuance of the Common
Stock for a consideration in whole or in part other than cash, the consideration
other than cash shall be deemed to be the fair value thereof as determined by
the Board of Directors irrespective of any accounting treatment.

                             (e) In the case of the issuance (whether before, on
or after the applicable Purchase Date) of options, warrants or other rights to
purchase or subscribe for



                                        8

<PAGE>   9

Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options, warrants or other rights to purchase or subscribe for
such convertible or exchangeable securities, the following provisions shall
apply for all purposes of this subsection C.4.d.(1) and subsection C.4.d.(2):

                                    i)      The aggregate maximum number of
               shares of Common Stock deliverable upon exercise (assuming the
               satisfaction of any conditions to exercisability, including
               without limitation, the passage of time, but without taking into
               account potential antidilution adjustments) of such options,
               warrants, or other rights to purchase or subscribe for Common
               Stock shall be deemed to have been issued at the time such
               options, warrants or other rights were issued and for a
               consideration equal to the consideration (determined in the
               manner provided in subsections C.4.d.(1)(c) and C.4.d.(1)(a)), if
               any, received by this Corporation upon the issuance of such
               options, warrants or other rights plus the minimum exercise price
               provided in such options, warrants or other rights (without
               taking into account potential antidilution adjustments) for the
               Common Stock covered thereby.

                                    ii)     The aggregate maximum number of
               shares of Common Stock deliverable upon conversion of or in
               exchange (assuming the satisfaction of any conditions to
               convertibility or exchangeability, including, without limitation,
               the passage of time, but without taking into account potential
               antidilution adjustments) for any such convertible or
               exchangeable securities or upon the exercise of options, warrants
               or other rights to purchase or subscribe for such convertible or
               exchangeable securities and subsequent conversion or exchange
               thereof shall be deemed to have been issued at the time such
               securities were issued or such options, warrants, or other rights
               were issued and for a consideration equal to the consideration,
               if any, received by this Corporation for any such securities and
               related options, warrants or other rights (excluding any cash
               received on account of accrued interest or accrued dividends),
               plus the minimum additional consideration, if any, to be received
               by this Corporation (without taking into account potential
               antidilution adjustments) upon the conversion or exchange of such
               securities or the exercise in full of any related options,
               warrants or other rights (the consideration in each case to be
               determined in the manner provided in subsections C.4.d.(1)(c) and
               C.4.d.(1)(a)).

                                    iii) In the event of any change in the
               number of shares of Common Stock deliverable or in the
               consideration payable to this Corporation upon exercise of such
               options, warrants or other rights or upon conversion of or in
               exchange for such convertible or exchangeable securities,
               including, but not limited to, a change resulting from the
               antidilution provisions thereof, the Conversion Price of the
               Series A Preferred Stock to the extent in any way affected by or
               computed using such options, warrants, or other rights or
               securities, shall be recomputed to reflect such change, but no
               further adjustment shall be made for the actual issuance of
               Common Stock or any payment of such



                                        9

<PAGE>   10

               consideration upon the exercise of any such options, warrants or
               other rights or the conversion or exchange of such securities.

                                    iv)     Upon the expiration of any such
               options, warrants or other rights, the termination of any such
               rights to convert or exchange or the expiration of any options,
               warrants or other rights related to such convertible or
               exchangeable securities, the Conversion Price of the Series A
               Preferred Stock, to the extent in any way affected by or computed
               using such options, warrants or other rights or securities or
               options, warrants or other rights related to such securities,
               shall be recomputed to reflect the issuance of only the number of
               shares of Common Stock (and convertible or exchangeable
               securities which remain in effect) actually issued upon the
               exercise of such options, warrants or other rights, upon the
               conversion or exchange of such securities or upon the exercise of
               the options, warrants or other rights related to such securities.

                                    v)      The number of shares of Common Stock
               deemed issued and the consideration deemed paid therefor pursuant
               to subsections C.4.d.(1)(e)(i) and (ii) shall be appropriately
               adjusted to reflect any change, termination or expiration of the
               type described in either subsection C.4.d.(1)(e)(iii) or (iv).

                      (2) "Additional Stock" shall mean any shares of Common
Stock issued (or deemed to have been issued pursuant to subsection C.4.d.(1)(e))
by this Corporation after the Purchase Date other than

                             (a) shares of Common Stock issued or issuable upon
               exercise of Warrants to purchase up to 4% of this Corporation's
               outstanding stock and granted to Imperial Bank on or about the
               Purchase Date,

                             (b) shares of Common Stock issued or issuable i) in
               a public offering before or in connection with which all
               outstanding shares of Series A Preferred Stock will be converted
               to Common Stock or ii) upon exercise of warrants or rights
               granted to underwriters in connection with such a public
               offering.

                      (3) In the event this Corporation should at any time or
from time to time after the Purchase Date fix a record date for the effectuation
of a split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in additional shares of Common Stock or other securities or
rights convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the Conversion
Price of the Series A Preferred Stock shall be appropriately decreased so that
the number of shares



                                       10

<PAGE>   11

of Common Stock issuable on conversion of each share of such series shall be
increased in proportion to such increase of the aggregate of shares of Common
Stock outstanding and those issuable with respect to such Common Stock
Equivalents with the number of shares issuable with respect to Common Stock
Equivalents determined from time to time in the manner provided for deemed
issuances in subsection 4.d.(1)(e).

                      (4) If the number of shares of Common Stock outstanding at
any time after the Purchase Date is decreased by a combination of the
outstanding shares of Common Stock then, following the record date of such
combination, the Conversion Price for the Series A Preferred Stock shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be decreased in proportion to such
decrease in the outstanding shares of Common Stock as a result of such
combination.

               e. Other Distributions. In the event this Corporation shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by this Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection C.4.d.(3), then,
in each such case for the purpose of this subsection C.4.e., the holders of the
Series A Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of this Corporation into which their shares of Series A Preferred Stock
are convertible as of the record date fixed for the determination of the holders
of Common Stock of this Corporation entitled to receive such distribution.

               f. Recapitalizations. If at any time or from time to time there
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section C.4 or Section C.2) provision shall be made so that the holders of
the Series A Preferred Stock shall thereafter be entitled to receive upon
conversion of the Series A Preferred Stock the number of shares of stock or
other securities or property of this Corporation or otherwise, to which a holder
of Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section C.4 with respect to the rights of
the holders of the Series A Preferred Stock after the recapitalization to the
end that the provisions of this Section C.4 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series A Preferred Stock) shall be applicable after that event
as nearly equivalent as may be practicable.

               g. No Impairment. This Corporation will not, by amendment of its
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
Corporation, but will at all times in good faith assist in the carrying out of
all he provisions of this Section C.4 and in the taking of all such action as
may bc necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A Preferred Stock against impairment.

               h.     No Fractional Shares and Certificate as to Adjustments.

                      (1)    No fractional shares shall be issued upon the 
conversion of any share or shares of the Series A Preferred Stock and the number
of shares of Common Stock to be issued shall be rounded to the nearest whole
share. Whether or not fractional shares are issuable upon such conversion shall
be determined on the basis of the total number of shares of Series A Preferred
Stock the holder is at the time converting into Common Stock and the number of
shares of Common Stock issuable upon such aggregate conversion.

                      (2) Upon the occurrence of each adjustment or readjustment
of the Conversion Price of Series A Preferred Stock pursuant to this Section
C.4, this Corporation, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A Preferred Stock a certificate setting forth such adjustment
or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. This Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock furnish or cause to be furnished
to such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Price for such series of Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock and the amount, if
any, of other property which at the time would be received upon the conversion
of a share of Series A Preferred Stock.

               i. Notices of Record Date. In the event of any taking by this
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, this
Corporation shall mail to each holder of Series A Preferred Stock, at least 20
days prior to the date specified therein, a notice specifying the date on which
any such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

               j. Reservation of Stock Issuable Upon Conversion. This
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock and any Premium
attributable to such shares of Series A Preferred Stock such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Series A Preferred Stock and any
Premium attributable to such shares of Series A Preferred Stock; and if at any
time the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of the Series
A Preferred Stock and any Premium attributable to such Series A Preferred Stock,
in addition to such other remedies as shall be available to the holder of such
Preferred Stock, this Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite stockholder approval of any necessary amendment to these articles.

               k. Notices. Any notice required by the provisions of this Section
C.4 to be given to the holders of shares of Series A Preferred Stock shall be
deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of this
Corporation.

               5. Voting Rights. The holder of each share of Series A Preferred
Stock shall have the right to one vote for each share of Common Stock into which
such Series A Preferred Stock could then be converted, and with respect to such
vote, such holder shall have full voting rights and powers equal to the voting
rights and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any stockholders' meeting in
accordance with the bylaws of this Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not,
however, be permitted and any fractional voting rights available on an
as-converted basis (after aggregating all shares into which shares of Series A
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half being rounded upward).

               6. Protective Provisions. Subject to the rights of series of
Preferred Stock which may from time to time come into existence, so long as at
least fifty percent (50%) of the originally issued shares of Series A Preferred
Stock are outstanding, this Corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least a majority of the then outstanding shares of Series A Preferred Stock,
voting together as a single class, and Common Stock, voting separately as a
class, voting in accordance with Section C.5, except where otherwise required by
law:

               a. sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other Corporation (other than a wholly-owned subsidiary Corporation) or
effect any transaction or series of related transactions in which more than
fifty percent (50%) of the voting power of this Corporation is disposed of; or

               b. alter or change the rights, preferences or privileges of the
shares of Series A Preferred Stock so as to affect adversely the shares; or

               c. increase or decrease (other than by redemption or conversion)
the total number of authorized shares of Series A Preferred Stock; or

               d. authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security, having a preference over, or being on a parity with,
the Series A Preferred Stock with respect to voting, dividends or upon
Liquidation; or

               e. redeem, purchase or otherwise acquire (or pay into or set
aside for a sinking fund for such purpose) any share or shares of Preferred
Stock or Common Stock; provided, however, that this restriction shall not apply
to the redemption of Series A Preferred Stock as provided in Section C.3 or to
the repurchase of shares of Common Stock from



                                       13

<PAGE>   14

employees, officers, directors, consultants or other persons performing services
for this Corporation or any subsidiary pursuant to agreements under which this
Corporation has the option to repurchase such shares on terms approved by the
Board of Directors upon the occurrence of certain events, such as the
termination of employment; or

               f.     effect a reclassification or recapitalization of the 
outstanding capital stock of this Corporation; or

               g. increase the authorized number of directors of this
Corporation beyond nine directors;

               h. amend or repeal any provision of, or add any provision to this
Corporation's Certificate of Incorporation or Bylaws to change the rights of the
Series A Preferred Stock, or increase or decrease the number of authorized
shares of stock of this Corporation; or

               i. create any bonds, notes or other obligations convertible into,
exchangeable for or having option rights to purchase shares of stock with any
preference or priority as to dividends or assets superior to or on a parity with
that of the Preferred.

               7. Status of Converted or Redeemed Stock. In the event any shares
of Series A Preferred Stock shall be redeemed or converted pursuant to Section
C.3 or Section C.4 hereof, the shares so converted or redeemed shall be
cancelled and shall not be issuable by this Corporation. The Certificate of
Incorporation of this Corporation shall be appropriately amended to effect the
corresponding reduction in this Corporation's authorized capital stock.

                                   ARTICLE VI

               In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, amend or
repeal from time to time any or all of the Bylaws of this Corporation. Any
By-Laws made by the directors under the powers conferred hereby may be amended
or repealed by the directors or by the stockholders. Notwithstanding the
foregoing and anything contained in this Amended and Restated Certificate of
Incorporation to the contrary, the By-Laws shall not be amended or repealed by
the stockholders, and no provision inconsistent therewith shall be adopted by
the stockholders, without the affirmative vote of the holders of at least
66-2/3% of the voting power of all shares of the Corporation entitled to vote
generally in the election of directors, voting together as a single class.

                                   ARTICLE VII

               Notwithstanding any other provision contained in this Amended and
Restated Certificate of Incorporation and notwithstanding that a lesser
percentage may be specified by law, the By-Laws or otherwise, this Article VII
and Articles VIII, IX, X and XI of this Amended and Restated Certificate of
Incorporation shall not be amended or repealed, and no provision inconsistent
therewith or providing for cumulative voting in the election of directors shall
be adopted, unless such adoption, amendment or repeal is approved by the
affirmative vote



                                       14

<PAGE>   15

of holders of at least 66-2/3% of the voting power of all shares of capital
stock of the Corporation entitled to vote generally for the election of
directors; provided, however, that the provisions of this Article VII shall not
apply unless and until the Corporation shall have completed an IPO.

                                  ARTICLE VIII

               The business and affairs of the Corporation shall be managed by
and under the direction of the Board of Directors (the "Board"). The Board may
exercise all such authority and powers of the Corporation and do all such lawful
acts and things as are not by statute or this Amended and Restated Certificate
of Incorporation directed or required to be exercised or done by the
stockholders.

               A. Number of Directors. The number of directors comprising the
entire Board shall, at the time of filing of this Amended and Restated
Certificate of Incorporation with the Secretary of State of the State of
Delaware (the "Effective Time"), be the number of directors then in office and
shall thereafter, subject to the right, if any, of holders of Preferred Stock to
elect directors under specified circumstances, be such number as may be fixed
from time to time exclusively by the Board by action of a majority of the
directors then in office provided that in no event shall such number be fewer
than three or greater than nine, unless approved by action of not less than
two-thirds of the directors then in office. No director need be a stockholder.

               B. Classes and Terms of Directors. The directors shall be divided
into three classes: Class I, Class II and Class III. The number of directors
comprising each class (assuming no vacancy in any class) shall be as nearly
equal in number as possible based upon the number of directors comprising the
entire Board. The Board shall, at or before the first meeting of the Board
following the Effective Time, designate the class to which each director then
serving shall be a member. The initial term of the directors in Class I shall
extend until the first annual meeting of stockholders following the end of the
Corporation's fiscal year ending December 31, 1998; the initial term of the
directors in Class II shall extend until the first annual meeting of
stockholders following the end of the Corporation's fiscal year ending December
31, 1999; and the initial term of the directors in Class III shall extend until
the first annual meeting of stockholders following the end of the Corporation's
fiscal year ending 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.

               C. Allocation of Directors Among Classes in the Event of
Increases or Decreases in the Number of Directors. Subject to the rights of the
holder of any class or series of preferred stock then outstanding, in the event
of any increase or decrease in the authorized number of directors, (i) each
director then serving as such shall nevertheless continue as director of the
class of which he is a member until the expiration of his current term or his
prior death, retirement or resignation and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors so as to ensure that
the number of directors comprising each class (assuming no



                                       15

<PAGE>   16

vacancy in any class) shall be as nearly equal in number as possible based on
the number of directors comprising the entire Board. To the extent possible,
consistent with the foregoing rule, any newly created directorships shall be
added to those classes whose terms of office are to expire at the latest dates
following such allocation, and any newly eliminated directorships shall be
subtracted from those classes whose terms of office are to expire at the
earliest dates following such allocation, unless otherwise provided for from
time to time by resolution adopted by a majority of the directors then in
office, although less than a quorum.

               D. Newly-Created Directorships and Vacancies. Subject to the
rights of the holders of any class or series of Preferred Stock then
outstanding, newly created directorships resulting from any increase in the
number of directors or any vacancies in the Board resulting from death,
resignation, retirement, disqualification, removal from office or any other
cause may be filled by the Board (and not by the stockholders unless there are
no directors then 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. A director elected to fill
a newly created directorship or other vacancy shall hold office for the
remainder of the full term of the class of directors in which the new
directorship was created or the vacancy occurred and until such director's
successor has been elected and qualified.

               E. Removal of Directors. Subject to the rights of the holders of
any class or series of Preferred Stock then outstanding, the directors or any
director may be removed from office any time, but only for cause, at a meeting
called for that purpose, and only by the affirmative vote of the holders of at
least 66-2/3% of the voting power of all shares of the Corporation entitled to
vote generally in the election of directors, voting together as a single class;
provided, however, that the directors or any director may be removed with or
without cause, by the affirmative vote of the holders of at least a majority of
such voting power, at any time prior to the completion of an IPO.

               F. Rights of Holders of Preferred Stock. Notwithstanding the
foregoing provisions of this Article VIII, whenever the holders of any one or
more classes or series of Preferred Stock issued by the Corporation shall have
the right, voting separately by class or series, to elect directors at an annual
or special meeting of stockholders, the election, term of office, filling of
vacancies and other features of such directorships shall be governed by the
rights and preferences of such Preferred Stock, and such directors so elected
shall not be divided into classes pursuant to this Article VIII unless expressly
provided by such rights and preferences.

               G. Written Ballot Not Required. The election of directors need
not be By written ballot unless the By-Laws of the Corporation shall so provide.

                                   ARTICLE IX

               The By-Laws of the Corporation may provide, without limitation,
requirements relating to the notice and conduct of annual meetings, special
meetings, and the nomination and election of directors of the Corporation.

law or in this Amended and Restated Certificate of Incorporation, the Board (and
any committee of the Board) is expressly authorized, to the extent permitted by
law, to take such action or actions as the Board or such committee may determine
to be reasonably necessary or desirable to (a) encourage any person to enter
into negotiations with the Board and management of the Corporation with respect
to any transaction which may result in a change in control of the Corporation
which is proposed or initiated by such person or (b) contest or oppose any such
transaction which the Board or such committee determines to be unfair, abusive
or otherwise undesirable with respect to the Corporation and its business,
assets or properties or the stockholders of the Corporation, including, without
limitation, the adoption of plans or the issuance of rights, options, capital
stock, notes, debentures or other evidences of indebtedness or other securities
of the Corporation, which rights, options, capital stock, notes, evidences of
indebtedness and other securities (i) may be exchangeable for or convertible
into cash or other securities on such terms and conditions as may be determined
by the Board or such committee and (ii) may provide that any holder or class of
holders thereof designated by the Board or any such committee will be treated
differently than, and unequally to, all other holders in respect of the terms,
conditions, provisions and rights of such securities.

                                   ARTICLE XI

               Subject to the rights, if any, of holders of any class or series
of Preferred Stock then outstanding, (i) stockholders are not permitted to call
a special meeting of stockholders or to require the Board or officers of the
Corporation to call such a special meeting, (ii) a special meeting of
stockholders may only be called by a majority of the Board, by the President or
by the Chairman of the Board, (iii) the business permitted to be conducted at a
special meeting of stockholders shall be limited to matters properly brought
before the meeting by or at the direction of the Board, and (iv) any action
required or permitted to be taken by the stockholders must be taken at a duly
called and convened annual meeting or special meeting of stockholders and cannot
be taken by consent in writing; provided, however, that the provisions of the
foregoing clause (iv) shall not apply prior to the completion of an IPO.

                                   ARTICLE XII

               A director of this Corporation shall not be personally liable to
this Corporation 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 this Corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation Law
of the State of Delaware, or (iv) for any transaction from which the director
derived an improper personal benefit. Neither the amendment nor repeal of this
Article XII, nor the adoption of any provision of the Certificate of
Incorporation or Bylaws or of any statute inconsistent with this Article XII,
shall eliminate or reduce the effect of this Article XII in respect of any acts
or omissions occurring, or any causes of action, suits or claims that, but for
this Article XII, would accrue or arise, prior to such amendment, repeal or
adoption of an inconsistent provision. If

stockholder proposes to nominate for election or re-election as a Director, (i)
the name, age, business address and residence address of the person, (ii) the
principal occupation or employment of the person, (iii) the class, series and
number of shares of capital stock of the Corporation which are beneficially
owned by the person and (v) any other information relating to the person that is
required to be disclosed in solicitations for proxies for election of Directors
pursuant to the Rules and Regulations of the Securities and Exchange Commission
under Section 14 of the Securities Exchange Act of 1934, as amended; and (b) as
to the stockholder giving the notice (i) the name and record address of the
stockholder, (ii) the class, series and number of shares of capital stock of the
Corporation which are beneficially owned by the stockholder and (iii) a
description of all arrangements or understandings between the stockholder and
each nominee and any other person or persons (naming such person or persons)
pursuant to which the nomination or nominations are to be made by the
stockholder. Such notice shall be accompanied by the executed consent of each
nominee to serve as a Director if so elected. The Corporation may require any
proposed nominee to furnish such other information as may reasonably be required
by the Corporation to determine the eligibility of such proposed nominee to
serve as a Director of the Corporation. No person shall be eligible for election
as a Director of the Corporation by the holders of Common Stock of the
Corporation unless nominated in accordance with the procedures set forth herein.
The officer of the Corporation presiding at an annual meeting shall, if the
facts warrant, determine that a nomination was not made in



                                        3

<PAGE>   4

accordance with the foregoing procedure and, if he should so determine, he shall
so declare to the meeting and the defective nomination shall be disregarded.

               Section 10. Advance Notification of Business to be Transacted at
Stockholder Meetings. To be properly brought before the annual or any special
meeting of stockholders, business must be either (a) specified in the notice of
meeting (or any supplement or amendment thereto) given by or at the direction of
the Board of Directors or any committee appointed by the Board of Directors, (b)
otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (c) otherwise properly brought before an annual meeting
by a stockholder. In addition to any other applicable requirements, for business
to be properly brought before any annual meeting of stockholders by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
Corporation not less than 60 days nor more than 90 days prior to the meeting;
provided, however, that in the event that less than 70 days' notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder to be timely must be so received not later than the
close of business on the fifteenth day following the day on which such notice of
the date of the meeting was mailed or such public disclosure was made, whichever
first occurs. Such stockholder's notice to the Secretary shall set forth as to
each matter the stockholder proposes to bring before the meeting (i) a brief
description of the business desired to be brought before the meeting and the
reasons for conducting such business at the meeting, (ii) the name and record
address of the stockholder proposing such business, (iii) the class, series and
number of shares of capital stock of the Corporation which are beneficially
owned by the stockholder and (iv) any material interest of the stockholder in
such business.

               No business shall be conducted at the annual or any special
meeting of stockholders unless it is properly brought before the meeting in
accordance with the procedures set forth in this Section 10, provided, however,
that nothing in this Section 10 shall be deemed to preclude discussion by any
stockholder of any business properly brought before the meeting in accordance
with the procedures set forth in this Section 10. The officer of the Corporation
presiding at the meeting shall, if the facts warrant, determine that business
was not properly brought before the meeting in accordance with the provisions of
this Section 10 and, if he should so determine, he shall so declare to the
meeting and any such business not properly brought before the meeting shall not
be transacted.

               Section 11. Compliance with Securities and Exchange Act of 1934.
Notwithstanding any other provision of these bylaws, on completion of an IPO the
Corporation shall be under no obligation to include any stockholder proposal in
its proxy statement materials or otherwise present any such proposal to
stockholders at a special or annual meeting of stockholders if the Board of
Directors reasonably believes that the proponents thereof have not complied with
Sections 13 and 14 of the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder, and the Corporation shall not be
required to include in its proxy statement material to stockholders any
stockholder proposal not required to



                                        4

<PAGE>   5

be included in its proxy material to stockholders in accordance with such Act,
rules, or regulations.

               Section 12. Adjournment of Meetings. If a quorum shall not be
present or represented at any meeting of the stockholders, the stockholders
entitled to vote thereat, present in person or represented by proxy, shall have
power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present or represented. At
such adjourned meeting at which a quorum shall be present or represented any
business may be transacted which might have been transacted at the meeting as
originally noticed. If the adjournment is for more than thirty days, or if after
the adjournment a new record date is fixed for the adjourned meeting, a notice
of the adjourned meeting shall be given to each stockholder of record entitled
to vote at the meeting.

               Section 13. Voting. Unless otherwise provided in the certificate
of incorporation, each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder, but no proxy shall be voted after
three years from its date, unless the proxy provides for a longer period.

present thereat may adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present.

by the certificate of incorporation or these bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.
Written consents representing actions taken by the Board or committee may be
executed by telex, telecopy or other facsimile transmission, and such facsimile

               Section 8. Meetings by Conference Telephone. Unless otherwise
restricted by the certificate of incorporation or these bylaws, members of the
Board of Directors, or any committee established by the Board of Directors, may
participate in a meeting of the Board of Directors, or such committee, by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and such

be presided over by the Chairman, if any, or in his absence by the Vice
Chairman, if any, or in the absence of the foregoing persons by a chairman

of any committee, who may replace any absent or disqualified member at any
meeting of the committee.

may unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.

                      Any such committee, to the extent provided by resolution
of the Board of Directors, shall have and may exercise all the powers and
authority of the Board of Directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation to be
affixed to all papers which may require it; provided that no such committee
shall have power or authority in reference to (i) approving or adopting, or
recommending to the stockholders, any action or matter expressly required by the
General Corporation Law of Delaware to be submitted to stockholders for approval
or (ii) adopting, amending or repealing any bylaw of the corporation. Each
committee shall keep regular minutes of its meetings and report the same to the
Board of Directors when required.

Directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors and may be paid a fixed sum for attendance at each
meeting of the Board of Directors or a stated salary as Director. No such
payment shall preclude any Director from serving the corporation in any other
capacity and receiving compensation therefor. Members of special or standing
committees may be allowed like compensation for attending committee meetings.

        Section 2. THE REVOLVING CREDIT FACILITY.

        Section 2.1. COMMITMENT TO LEND. Subject to the terms and conditions set
forth in this Credit Agreement, each of the Banks severally agrees to lend to
the Borrowers and the Borrowers may borrow, repay, and reborrow from time to
time from the Closing Date to the Maturity Date, upon notice by the Borrowers to
the Agent given in accordance with Section 2.6, its Commitment Percentage of the
Revolving Credit Loans as are requested by the Borrowers, provided that the
outstanding amount of Revolving Credit Loans, unpaid Reimbursement Obligations,
and the Maximum Drawing Amount shall not exceed a maximum aggregate amount
outstanding of $25,000,000 at any time, as such amount may be reduced pursuant
to Section 2.2 hereof (the "Total Commitment"), and provided further that the
maximum amount of Loans and Letters of Credit available hereunder shall be
$17,000,000 until a CFO acceptable to the Banks has commenced employment with
the Borrowers. The Revolving Credit Loans shall be made pro rata in accordance
with each Bank's Commitment Percentage. Each request for a Loan hereunder shall
constitute a representation and warranty by the Borrowers that the conditions
set forth in Section 9 and Section 10, as the case may be, have been satisfied
on the date of such request.

        Section 2.2. REDUCTION OF TOTAL COMMITMENT.

        (a) The Borrowers shall have the right at any time and from time to time
upon five (5) Business Days' prior written notice to the Agent to reduce by
$1,000,000 or an integral multiple of $500,000 in excess thereof, or terminate
entirely, the Total Commitment, whereupon the Commitments of the Banks shall be
reduced pro rata in accordance with their respective Commitment Percentages of
the amount specified in such notice or, as the case may be, terminated. The
Agent will notify the Banks promptly after receiving any notice of the Borrowers
delivered pursuant to this Section 2.2.



<PAGE>   23
                                      -17-



        (b) No reduction or termination of the Commitments once made may be
revoked; the portion of the Commitments reduced or terminated may not be
reinstated; and amounts in respect of such reduced or terminated portion may not
be reborrowed.

        Section 2.3. THE REVOLVING CREDIT NOTES. The Revolving Credit Loans
shall be evidenced by separate promissory notes of the Borrowers in
substantially the form of Exhibit A hereto (each a "Revolving Credit Note"),
dated as of the Closing Date and completed with appropriate insertions. One
Revolving Credit Note shall be payable to the order of each Bank in a principal
amount equal to such Bank's Commitment or, if less, the outstanding amount of
all Revolving Credit Loans made by such Bank, plus interest accrued thereon, as
set forth below. The Borrowers irrevocably authorize each Bank to make or cause
to be made, in connection with a Drawdown Date of any Revolving Credit Loan or
at the time of receipt of any payment of principal on such Bank's Revolving
Credit Note, an appropriate notation on such Bank's records reflecting the
making of such Loan or the receipt of such payment (as the case may be). The
outstanding amount of the Loans set forth on such Bank's record shall be prima
facie evidence of the principal amount thereof owing and unpaid to such Bank,
but the failure to record, or any error in so recording, any such amount shall
not limit or otherwise affect the obligation of the Borrowers hereunder or under
any Revolving Credit Note to make payments of principal of or interest on any
Revolving Credit Note when due.

        Section 2.4. INTEREST ON REVOLVING CREDIT LOANS. The outstanding
principal amount of the Revolving Credit Loans shall bear interest at the rate
per annum equal to (a) the Base Rate plus the Applicable Base Rate Margin on
Base Rate Loans or (b) the Eurodollar Rate plus the Applicable Eurodollar Margin
on Eurodollar Loans. Interest shall be payable (i) quarterly in arrears on the
first Business Day of each calendar quarter, commencing April 1, 1998, on Base
Rate Loans, (ii) on the last day of the applicable Interest Period, and if such
Interest Period is longer than three (3) months, also on the day which is three
(3) months after the commencement of such Interest Period, on Eurodollar Loans,
and (iii) on the Maturity Date for all Revolving Credit Loans.

        Section 2.5. ELECTION OF EURODOLLAR RATE; NOTICE OF ELECTION; INTEREST
PERIODS; MINIMUM AMOUNTS.

                     (a) At the Borrowers' option, so long as no Default or
Event of Default has occurred and is then continuing, the Borrowers may (i)
elect to convert any Revolving Credit Loan which is a Base Rate Loan or a
portion thereof to a Eurodollar Loan, (ii) at the time of any Loan and Letter of
Credit Request, specify that a requested Revolving Credit Loan shall be a
Eurodollar Loan, or (iii) upon expiration of the applicable Interest Period,
elect to maintain an existing Eurodollar Loan as such, provided that the
Borrowers give notice to the Agent pursuant to Section 2.5(b) hereof. Upon
determining any Eurodollar Rate, the Agent shall forthwith



<PAGE>   24
                                      -18-



provide notice thereof to the Borrowers and the Banks, and each such notice to
the Borrowers and the Banks shall be considered prima facie correct and binding,
absent manifest error.

                     (b) Three (3) Eurodollar Business Days prior to the making
of any Eurodollar Loan or the conversion of any Base Rate Loan to a Eurodollar
Loan, or, in the case of an outstanding Eurodollar Loan, the expiration date of
the applicable Interest Period, the Borrowers shall give telephonic notice
(confirmed by telecopy on the same Eurodollar Business Day) to the Agent not
later than 11:00 a.m. (Boston time) of their election pursuant to Section
2.5(a). Each such notice delivered to the Agent shall specify the aggregate
principal amount of the Loans to be borrowed or maintained as or converted to
Eurodollar Loans and the requested duration of the Interest Period that will be
applicable to such Eurodollar Loan, and shall be irrevocable and binding upon
the Borrowers. If the Borrowers shall fail to give the Agent notice of their
election hereunder together with all of the other information required by this
Section 2.5(b) with respect to any Revolving Credit Loan, such Loan shall be
deemed a Base Rate Loan. In the event that the Borrowers fail to provide any
such notice with respect to the continuation of any Eurodollar Loan as such,
then such Eurodollar Loan shall be automatically converted to a Base Rate Loan
at the end of the then expiring Interest Period relating thereto.

                     (c) Notwithstanding anything herein to the contrary, the
Borrowers may not specify an Interest Period that would extend beyond the
Maturity Date.

                     (d) All Revolving Credit Loans shall be in a minimum amount
of $100,000 or an integral multiple of $100,000 in excess thereof. In no event
shall the Borrowers have more than five (5) different maturities of Eurodollar
Loans outstanding at any time.

        Section 2.6. REQUESTS FOR REVOLVING CREDIT LOANS. The Borrowers shall
give to the Agent written notice in the form of Exhibit B hereto (or telephonic
notice confirmed by telecopy on the same Business Day in the form of Exhibit B
hereto) of each Revolving Credit Loan requested hereunder (a "Loan and Letter of
Credit Request") not later than (a) 11:00 a.m. Boston time one (1) Business Day
prior to the proposed Drawdown Date of any Revolving Credit Loan which is a Base
Rate Loan, or (b) 11:00 a.m. Boston time three (3) Eurodollar Business Days
prior to the proposed Drawdown Date of any Eurodollar Loan. Each such notice
shall be given by the Borrowers and shall specify the principal amount of the
Revolving Credit Loan requested and shall include a current Loan and Letter of
Credit Request reflecting the Maximum Drawing Amount. Each Loan and Letter of
Credit Request shall be irrevocable and binding on the Borrowers and shall
obligate the Borrowers to accept the Revolving Credit Loan requested from the
Banks on the proposed Drawdown Date. Each of the representations and warranties
made by or on behalf of the Borrowers to the Banks or the Agent in this Credit
Agreement or any other Loan Document shall be true and correct in all material
respects when made and shall, for



<PAGE>   25
                                      -19-



all purposes of this Credit Agreement, be deemed to be repeated on and as of the
date of the submission of any Loan and Letter of Credit Request and on and as of
the Drawdown Date of such Revolving Credit Loan, or the date of issuance of such
Letter of Credit (except to the extent of changes resulting from transactions
contemplated or permitted by this Credit Agreement and the other Loan Documents
and changes occurring in the ordinary course of business that singly or in the
aggregate are not materially adverse, or to the extent that such representations
and warranties expressly relate solely to an earlier date). The Agent shall
promptly notify each Bank of each Loan and Letter of Credit Request received by
the Agent.

        Section 2.7. FUNDS FOR REVOLVING CREDIT LOANS.

        (a) Not later than 1:00 p.m. (Boston time) on the proposed Drawdown Date
of any Revolving Credit Loan, each of the Banks will make available to the
Agent, at the Agent's Head Office, in immediately available funds, the amount of
such Bank's Commitment Percentage of the amount of the requested Revolving
Credit Loans. Upon receipt from each Bank of such amount, and upon receipt of
the documents required by Section ss.9 and 10 and the satisfaction of the other
conditions set forth therein, to the extent applicable, the Agent will make
available to the Borrowers in immediately available funds the aggregate amount
of such Revolving Credit Loans made available to the Agent by the Banks. The
failure or refusal of any Bank to make available to the Agent at the aforesaid
time and place on any Drawdown Date the amount of its Commitment Percentage of
the requested Revolving Credit Loans shall not relieve any other Bank from its
several obligation hereunder to make available to the Agent the amount of such
other Bank's Commitment Percentage of any requested Revolving Credit Loans.

        (b) The Agent may, unless notified to the contrary by any Bank prior to
a Drawdown Date, assume that such Bank has made available to the Agent on such
Drawdown Date the amount of such Bank's Commitment Percentage of the Revolving
Credit Loans to be made on such Drawdown Date, and the Agent may (but shall not
be required to), in reliance upon such assumption, make available to the
Borrowers a corresponding amount. If any Bank makes available to the Agent such
amount on a date after such Drawdown Date, such Bank shall pay to the Agent on
demand an amount equal to the product of (i) the average computed for the period
referred to in clause (iii) below, of the weighted average interest rate paid by
the Agent for federal funds acquired by the Agent during each day included in
such period, times (ii) the amount of such Bank's Commitment Percentage of such
Revolving Credit Loans, times (iii) a fraction, the numerator of which is the
number of days that elapse from and including such Drawdown Date to the date on
which the amount of such Bank's Commitment Percentage of such Revolving Credit
Loans shall become immediately available to the Agent, and the denominator of
which is 365. A statement of the Agent submitted to such Bank with respect to
any amounts owing under this paragraph shall be prima facie evidence, absent
manifest error, of the amount due and 



<PAGE>   26
                                      -20-



owing to the Agent by such Bank. If the amount of such Bank's Commitment
Percentage of such Revolving Credit Loans is not made available to the Agent by
such Bank within three (3) Business Days following such Drawdown Date, the Agent
shall be entitled to recover such amount from the Borrowers on demand, with
interest thereon at the rate per annum applicable to the Revolving Credit Loans
made on such Drawdown Date.

        Section 2.8. MATURITY OF THE LOANS. The Revolving Credit Loans shall be
due and payable on the Maturity Date. The Borrowers jointly and severally
promise to pay on the Maturity Date all Revolving Credit Loans outstanding on
such date, together with any and all accrued and unpaid interest thereon.

        Section 2.9. MANDATORY REPAYMENTS OF THE REVOLVING CREDIT LOANS. If at
any time the outstanding amount of the Revolving Credit Loans plus the Maximum
Drawing Amount plus unpaid Reimbursement Obligations exceeds the Total
Commitment, whether by reduction of the Total Commitment or otherwise, then the
Borrowers shall immediately pay the amount of such excess to the Agent for
application to the Revolving Credit Loans, or if no Revolving Credit Loans shall
be outstanding, to be held by the Agent as collateral security for the
Reimbursement Obligations, provided, however, that if the amount of cash
collateral held by the Agent pursuant to this Section 2.9 exceeds the amount of
the Obligations, the Agent shall return such excess to the Borrowers.

        Section 2.10. OPTIONAL PREPAYMENTS OR REPAYMENTS OF REVOLVING CREDIT
LOANS. The Borrowers shall have the right, at their election, to repay or prepay
the outstanding amount of the Revolving Credit Loans, as a whole or in part, at
any time without penalty or premium (other than the obligation to reimburse the
Banks and the Agent pursuant to Section 4.8 hereof). The Borrowers shall give
written notice to the Agent (or telephonic notice confirmed in writing) no later
than (a) 1:00 p.m. (Boston time) on the Business Day of the proposed prepayment
or repayment of any Base Rate Loan or (b) 1:00 p.m. (Boston time) three (3)
Eurodollar Business Days prior to the proposed prepayment or repayment of any
Eurodollar Loan, in each case specifying the proposed date of prepayment or
repayment of Revolving Credit Loans and the principal amount to be paid. Each
such partial repayment of the Revolving Credit Loans shall be $50,000 or an
integral multiple of $50,000 in excess thereof, and shall be accompanied by the
payment of accrued interest on the principal prepaid to the date of repayment
and shall be applied, in the absence of instruction by the Borrowers, first to
the principal of Base Rate Loans and then to the principal of Eurodollar Loans.
Each partial prepayment shall be allocated among the Banks, in proportion, as
nearly as practicable, to the respective unpaid principal amount of each Bank's
Revolving Credit Loans, with adjustments to the extent practicable to equalize
any prior repayments not exactly in proportion. Unless the Borrowers elect to
repay the total aggregate outstanding amount of the Revolving Credit Loans, the
Borrowers



<PAGE>   27
                                      -21-



may not elect to make any repayments which would reduce the total aggregate
outstanding amount of the Revolving Credit Loans to an amount less than $50,000.

        Section 3. LETTERS OF CREDIT.

        Section 3.1. LETTER OF CREDIT COMMITMENTS.

                     (a) Subject to the terms and conditions hereof and the
execution and receipt of a Loan and Letter of Credit Request reflecting the
Maximum Drawing Amount of all Letters of Credit (including the requested Letter
of Credit) and a Letter of Credit Application, the Agent, on behalf of the Banks
and in reliance upon the agreement of the Banks set forth in Section 3.1(b) and
upon the representations and warranties of the Borrowers contained herein,
agrees to issue standby letters of credit, in such form as may be requested from
time to time by the Borrowers and agreed to by the Agent; provided, however,
that, after giving effect to such request, the Maximum Drawing Amount shall not
exceed the lesser of (i) $5,000,000 or (ii) the Total Commitment minus the
aggregate outstanding amount of the Revolving Credit Loans. No Letter of Credit
shall have an expiration date later than the earlier of (i) one (1) year after
the date of issuance of the Letter of Credit (which may incorporate automatic
renewals for periods of up to one (1) year, provided that the Agent may, upon 30
days' notice to the beneficiary, cancel such Letter of Credit which has been
renewed beyond its initial one (1) year term), or (ii) thirty (30) days prior to
the Maturity Date.

                     (b) Each Bank severally agrees that it shall be absolutely
liable, without regard to the occurrence of any Default or Event of Default or
any other condition precedent whatsoever, to the extent of such Bank's
Commitment Percentage thereof, to reimburse the Agent on demand for the amount
of each draft paid by the Agent under each Letter of Credit issued in accordance
with the terms hereof to the extent that such amount is not reimbursed by the
Borrowers pursuant to Section 3.2 (such agreement for a Bank being called herein
the "Letter of Credit Participation" of such Bank).

                     (c) Each such payment made by a Bank shall be treated as
the purchase by such Bank of a participating interest in the Borrowers'
Reimbursement Obligation under Section 3.2 in an amount equal to such payment. 
Each Bank shall share in accordance with its participating interest in any
interest which accrues pursuant to Section 3.2.

        Section 3.2. REIMBURSEMENT OBLIGATION OF THE BORROWERS. In order to
induce the Agent to issue, extend and renew each Letter of Credit and the Banks
to participate therein, the Borrowers hereby agree to reimburse or pay to the
Agent with respect to each Letter of Credit issued, extended or renewed by the
Agent hereunder as follows:



<PAGE>   28
                                      -22-



                     (a) on each date that any draft presented under any Letter
of Credit is honored by the Agent or the Agent otherwise makes payment with
respect thereto, (i) the amount paid by the Agent under or with respect to such
Letter of Credit, and (ii) the amount of any taxes, fees, charges or other costs
and expenses whatsoever incurred by the Agent or any Bank in connection with any
payment made by the Agent or any Bank under, or with respect to, such Letter of
Credit; provided however, if the Borrowers do not reimburse the Agent on the
Drawdown Date, such amount shall, provided that no Event of Default under
Sections 12.1(h) or 12.1(i) has occurred, become automatically a Revolving
Credit Loan which is a Base Rate Loan advanced hereunder in an amount equal to
such sum; and

                     (b) upon the Maturity Date, or the termination of the Total
Commitment, or the acceleration of the Reimbursement Obligations in accordance
with Section 12, an amount equal to the Maximum Drawing Amount, which amount
shall be held by the Agent for the benefit of the Banks and the Agent as cash
collateral for all Reimbursement Obligations.

        Section 3.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented
or other demand for payment shall be made under any Letter of Credit, the Agent
shall notify the Borrowers of the date and amount of the draft presented or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment. On the date that such draft is paid or other
payment is made by the Agent, the Agent shall promptly notify the Banks of the
amount of any unpaid Reimbursement Obligation. No later than 3:00 p.m. (Boston
time) on the Business Day next following the receipt of such notice, each Bank
shall make available to the Agent, at the Agent's Head Office, in immediately
available funds, such Bank's Commitment Percentage of such Reimbursement
Obligation, together with an amount equal to the product of (a) the weighted
average, computed for the period referred to in clause (c) below, of the
interest rate paid by the Agent for federal funds acquired by the Agent during
each day included in such period, times (b) the amount equal to such Bank's
Commitment Percentage of such unpaid Reimbursement Obligation, times (c) a
fraction, the numerator of which is the number of days that have elapsed from
and including the date the Agent paid the draft presented for honor or otherwise
made payment until the date on which such Bank's Commitment Percentage of such
unpaid Reimbursement Obligation shall become immediately available to the Agent,
and the denominator of which is 365. The responsibility of the Agent to the
Borrowers and the Banks shall be only to determine that the documents (including
each draft) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit.

        Section 3.4. OBLIGATIONS ABSOLUTE. The Borrowers' obligations under this
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrowers may have or 



<PAGE>   29
                                      -23-



have had against the Agent, any Bank or any beneficiary of a Letter of Credit.
Subject to the obligations of the Banks pursuant to Article V of the Uniform
Commercial Code and the obligations of the Agent pursuant to the last sentence
of Section 3.3, the Borrowers further agree with the Agent and the Banks that
the Agent and the Banks shall not be responsible for, and the Borrowers'
Reimbursement Obligations under Section 3.2 shall not be affected by, among
other things, the validity or genuineness of documents or of any endorsements
thereon, even if such documents should in fact prove to be in any or all
respects invalid, fraudulent or forged, or any dispute between or among the
Borrowers, the beneficiary of any Letter of Credit or any financing institution
or other party to which any Letter of Credit may be transferred or any claims or
defenses whatsoever of the Borrowers against the beneficiary of any Letter of
Credit or any such transferee. The Agent and the Banks shall not be liable for
any error, omission, interruption or delay in transmission, dispatch or delivery
of any message or advice, however transmitted, in connection with any Letter of
Credit. The Borrowers agree that any action taken or omitted by the Agent or any
Bank under or in connection with each Letter of Credit and the related drafts
and documents, if done in good faith, shall be binding upon the Borrowers and
shall not result in any liability on the part of the Agent or any Bank to the
Borrowers.

        Section 3.5. RELIANCE BY AGENT. To the extent not inconsistent with
Section 3.4, the Agent shall be entitled to rely, and shall be fully protected
in relying upon, any Letter of Credit, draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel, independent
accountants or other experts selected by the Agent.

        Section 4. FEES, PAYMENTS, AND COMPUTATIONS; JOINT AND SEVERAL
LIABILITY.

        Section 4.1. FEES.

                     (a) COMMITMENT FEE. The Borrowers agree to pay to the
Agent, for the respective account of each Bank, a fee (the "Commitment Fee")
equal to the Applicable Commitment Rate multiplied by the average daily amount
of the unused portion of such Bank's Commitment during each calendar quarter or
portion thereof from the Closing Date to the Maturity Date (or to the date of
termination in full of the Total Commitment, if earlier). The Commitment Fee
shall be payable quarterly in arrears on the first day of each calendar quarter
for the immediately preceding calendar quarter commencing on April 1, 1998, with
a final payment on the Maturity Date.

                     (b) LETTER OF CREDIT FEES. The Borrowers shall pay a fee
(the "Letter of Credit Fee") equal to the Applicable L/C Margin multiplied by
the Maximum Drawing Amount of each Letter of Credit. Such Letter of Credit Fee
shall



<PAGE>   30
                                      -24-



be payable to the Agent for the account of the Banks, to be shared pro rata by
the Banks in accordance with their respective Commitment Percentages. The
Borrowers shall also pay a fee (the "Issuance Fee") to the Agent, for its own
account, equal to 0.125% per annum on the Maximum Drawing Amount of all Letters
of Credit issued by such Bank, plus its customary administrative charges. The
Letter of Credit Fee and the Issuance Fee shall be payable for the number of
days each Letter of Credit is outstanding, and shall be payable quarterly in
arrears on the first day of each calendar quarter for the immediately preceding
calendar quarter, and on the Maturity Date.

                     (c) CLOSING FEES. The Borrowers shall pay at closing any
fees owing to any of the Banks, as previously agreed between the Borrowers and
the Agent.

        Section 4.2. PAYMENTS.

                     (a) All payments of principal, interest, Reimbursement
Obligations, fees and any other amounts due hereunder or under any of the other
Loan Documents shall be made to the Agent, for the respective accounts of the
Banks and the Agent, to be received at the Agent's Head Office in immediately
available funds by 12:00 p.m. (Boston time) on any due date.

                     (b) All payments by the Borrowers hereunder and under any
of the other Loan Documents shall be made without setoff or counterclaim and
free and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions or
conditions of any nature now or hereafter imposed or levied by any jurisdiction
or any political subdivision thereof or taxing or other authority therein unless
the Borrowers are compelled by law to make such deduction or withholding. If any
such obligation is imposed upon the Borrowers with respect to any amount payable
by them hereunder or under any of the other Loan Documents, the Borrowers will
pay to the Agent, for the account of the Banks or (as the case may be) the
Agent, on the date on which such amount is due and payable hereunder or under
such other Loan Document, such additional amount in Dollars as shall be
necessary to enable the Banks or the Agent to receive the same net amount which
the Banks or the Agent would have received on such due date had no such
obligation been imposed upon the Borrowers. In the event that the Borrowers are
required to make such deduction or withholding as a result of the fact that a
Bank is organized outside of the United States, such Bank shall use its
reasonable best efforts to transfer its Loans to an affiliate organized within
the United States if such transfer would have no adverse effect on such Bank or
the Loans. The Borrowers will deliver promptly to the Bank certificates or other
valid vouchers for all taxes or other charges deducted from or paid with respect
to payments made by the Borrowers hereunder or under such other Loan Document.

                     (c) Whenever a payment hereunder or under any of the other
Loan Documents becomes due on a day that is not a Business Day, the due date for
such



<PAGE>   31
                                      -25-



payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension; provided that any Interest Period for any
Eurodollar Loan which ends on a day that is not a Eurodollar Business Day shall
end on the next succeeding Eurodollar Business Day unless the result of such
extension would be to carry such Interest Period into another calendar month, in
which event such Interest Period shall end on the immediately preceding
Eurodollar Business Day.

        Section 4.3. COMPUTATIONS. All computations of interest on Base Rate
Loans and of Commitment Fees, Letter of Credit Fees or other fees shall, unless
otherwise expressly provided herein, be based on a 365-day year (or 366-day
year, as applicable) and paid for the actual number of days elapsed. All
computations of interest on Eurodollar Loans shall, unless otherwise expressly
provided herein, be based on a 360-day year and paid for the actual number of
days elapsed.

        Section 4.4. CAPITAL ADEQUACY. If any present or future law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) or the interpretation thereof by a court or
governmental authority with appropriate jurisdiction affects the amount of
capital required or expected to be maintained by any Bank or the Agent or any
corporation controlling such Bank or the Agent, and such Bank or the Agent
determines that the amount of capital required to be maintained by it is
increased by or based upon the existence of such Bank's or the Agent's Loans,
Letter of Credit Participations or Letters of Credit, or commitment with respect
thereto, then such Bank or the Agent may notify the Borrowers of such fact. To
the extent that the costs of such increased capital requirements are not
reflected in the Base Rate (if relating to Base Rate Loans), the Borrowers and
such Bank or (as the case may be) the Agent shall thereafter attempt to
negotiate in good faith, within thirty (30) days of the day on which the
Borrowers receive such notice, an adjustment payable hereunder that will
adequately compensate such Bank or the Agent in light of these circumstances. If
the Borrowers and such Bank or the Agent are unable to agree to such adjustment
within thirty (30) days of the date on which the Borrowers receive such notice,
then commencing on the date of such notice (but not earlier than the effective
date of any such increased capital requirement), the fees payable hereunder
shall increase by an amount that will, in such Bank's or the Agent's reasonable
determination, provide adequate compensation. Each Bank and the Agent shall
allocate such cost increases among its customers in good faith and on an
equitable basis.


        Section 4.5. CERTIFICATE. A certificate setting forth any additional 
amounts payable pursuant to Section 4.4 and a reasonable explanation of such
amounts which are due, submitted by any Bank or the Agent to the Borrowers,
shall be conclusive, absent manifest error, that such amounts are due and owing.

        Section 4.6. INTEREST ON OVERDUE AMOUNTS. Overdue principal and (to the
extent permitted by applicable law) interest on the Loans and all other overdue
amounts payable hereunder or under any of the other Loan Documents shall bear
interest



<PAGE>   32
                                      -26-



compounded monthly and payable on demand at a rate per annum equal to the Base
Rate plus the Applicable Base Rate Margin plus two (2) percentage points (2.00%)
until such amount shall be paid in full (after, as well as before, judgment).

        Section 4.7. INTEREST LIMITATION. Notwithstanding any other term of this
Credit Agreement or any Note or any other document referred to herein or
therein, the maximum amount of interest which may be charged to or collected
from any person liable hereunder or under any Note by any Bank shall be
absolutely limited to, and shall in no event exceed, the maximum amount of
interest which could lawfully be charged or collected under applicable law
(including, to the extent applicable, the provisions of Section 5197 of the
Revised Statutes of the United States of America, as amended, 12 U.S.C. Section
85, as amended), so that the maximum of all amounts constituting interest under
applicable law, howsoever computed, shall never exceed as to any Person liable
therefor such lawful maximum, and any term of this Credit Agreement, the Notes,
the Letter of Credit Applications, or any other document referred to herein or
therein which could be construed as providing for interest in excess of such
lawful maximum shall be and hereby is made expressly subject to and modified by
the provisions of this paragraph.

        Section 4.8. EURODOLLAR INDEMNITY. The Borrowers agree to indemnify the
Banks and the Agent and to hold them harmless from and against any loss, cost or
expenses (including loss of anticipated profits) that the Banks and the Agent
may sustain or incur as a consequence of (a) default by the Borrowers in payment
of the principal amount of or any interest on any Eurodollar Loans as and when
due and payable, including any such loss or expense arising from interest or
fees payable by any Bank or the Agent to lenders of funds obtained by it in
order to maintain its Eurodollar Loans, (b) a prepayment of principal on any
Eurodollar Loan, including prepayments which are the result of acceleration by
the Banks, or (c) default by the Borrowers in making a borrowing or conversion
after the Borrowers have given (or are deemed to have given) notice pursuant to
Section 2.5 or Section 2.6, the making of any payment of a Eurodollar Loan or
the making of any conversion of any such Eurodollar Loan to a Base Rate Loan on
a day that is not the last day of the applicable Interest Period with respect
thereto, including interest or fees payable by any Bank to lenders of funds
obtained by it in order to maintain any such Loans.

            Section 4.9. ILLEGALITY; INABILITY TO DETERMINE EURODOLLAR RATE.
Notwithstanding any other provision of this Credit Agreement, if (a) the
introduction of, any change in, or any change in the interpretation of, any law
or regulation applicable to the Agent or any Bank shall make it unlawful, or any
central bank or other governmental authority having jurisdiction thereof shall
assert that it is unlawful, for any Bank or the Agent to perform its obligations
in respect of any Eurodollar Loans, or (b) if any Bank or the Agent shall
reasonably determine with respect to Eurodollar Loans that (i) by reason of
circumstances affecting any Eurodollar interbank market, adequate and reasonable
methods do not exist for ascertaining the Eurodollar Rate which would otherwise
be



<PAGE>   33
                                      -27-



applicable during any Interest Period, or (ii) deposits of Dollars in the
relevant amount for the relevant Interest Period are not available to such Bank
or the Agent in any Eurodollar interbank market, or (iii) the Eurodollar Rate
does not or will not accurately reflect the cost to such Bank or the Agent of
obtaining or maintaining the applicable Eurodollar Loans during any Interest
Period, then such Bank or the Agent shall promptly give telephonic, telex or
cable notice of such determination to the Borrowers (which notice shall be
conclusive and binding upon the Borrowers). Upon such notification by such Bank
or the Agent, the obligation of such Bank or the Agent to make Eurodollar Loans
shall be suspended until such Bank or the Agent determines that such
circumstances no longer exist, and the outstanding Eurodollar Loans shall
continue to bear interest at the applicable rate based on the Eurodollar Rate
until the end of the applicable Interest Period, and thereafter shall be deemed
converted to Base Rate Loans in equal principal amounts.

        Section 4.10. ADDITIONAL COSTS, ETC. If any present or future applicable
law, which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank by any central bank or other fiscal, monetary or
other authority (whether or not having the force of law), shall impose on any
Bank any tax, levy, impost, duty, charge fees, deduction or withholdings of any
nature or requirements with respect to this Credit Agreement, the other Loan
Documents, the Loans, such Bank's Commitment, the Letters of Credit or any class
of loans or commitments or letters of credit of which any of the Loans, the
Commitments or the Letters of Credit forms a part, and the result of any of the
foregoing is:

                     (i) to increase the cost to such Bank of making, funding,
issuing, renewing, extending or maintaining the Loans, such Bank's Commitment,
or the Letters of Credit; or

                     (ii) to reduce the amount of principal, interest or other
amount payable to such Bank hereunder on account of such Bank's Commitment, the
Loans, or drawings under the Letters of Credit, or

                     (iii) to require such Bank to make any payment or to forego
any interest or other sum payable hereunder, the amount of which payment or
foregone interest or other sum is calculated by reference to the gross amount of
any sum receivable or deemed received by such Bank from the Borrowers hereunder,

then, and in each such case, the Borrowers will, upon demand made by such Bank
at any time and from time to time and as often as the occasion therefor may
arise, pay to such Bank such additional amounts as will be sufficient to
compensate such Bank for such additional cost, reduction, payment or foregone
interest or other sum (after such



<PAGE>   34
                                      -28-


Bank shall have allocated the same fairly and equitably among all customers of
any class generally affected thereby).

        Section 4.11. REPLACEMENT OF BANKS. If any Bank (an "Affected Bank") (i)
makes demand upon the Borrowers for (or if the Borrowers are otherwise required
to pay) amounts pursuant to Sections 4.4 or 4.10 or (ii) is unable to
make or maintain Eurodollar Loans as a result of a condition described in
Section 4.9, the Borrowers may, within 90 days of receipt of such demand or
notice (or the occurrence of such other event causing the Borrowers to be
required to pay such compensation or causing Section 4.9 to be applicable), by
notice in writing to the Agent and such Affected Bank (a "Replacement Notice")
(A) request the Affected Bank to cooperate with the Borrowers in obtaining a
replacement bank satisfactory to the Agent and the Borrowers (the "Replacement
Bank"); (B) request the non-Affected Banks to acquire and assume all of the
Affected Bank's Loans and Commitment, as provided herein, but none of such Banks
shall be under an obligation to do so; or (C) designate a Replacement Bank
reasonably satisfactory to the Agent. If any satisfactory Replacement Bank shall
be obtained, and/or any of the non-Affected Banks shall agree to acquire and
assume all of the Affected Bank's Loans and Commitment, then such Affected Bank
shall, so long as no Event of Default shall have occurred and be continuing,
assign, in accordance with Section 17, all of its Commitment, Loans, Notes and
other rights and obligations under this Credit Agreement and all other Loan
Documents to such Replacement Bank or non-Affected Banks, as the case may be, in
exchange for payment of the principal amount so assigned and all interest and
fees accrued on the amount so assigned, plus all other Obligations then due and
payable to the Affected Bank; provided, however, that (i) such assignment shall
be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Affected Bank and such Replacement
Bank and/or non-Affected Banks, as the case may be, and (ii) prior to any such
assignment, the Borrowers shall have paid to such Affected Bank all amounts
properly demanded and unreimbursed under Sections 4.4, 4.8, 4.9 and 4.10.
Upon the effective date of such assignment, the Borrowers shall issue
replacement Notes to such Replacement Bank and/or non-Affected Banks, as the
case may be, and such institution shall become a "Bank" for all purposes under
this Credit Agreement and the other Loan Documents.


        Section 4.12. CONCERNING JOINT AND SEVERAL LIABILITY OF THE BORROWERS.

        (a) Each of the Borrowers is accepting joint and several liability
hereunder and under the other Loan Documents in consideration of the financial
accommodations to be provided by the Banks under this Credit Agreement, for the
mutual benefit, directly and indirectly, of each of the Borrowers and in
consideration of the undertakings of each other Borrower to accept joint and
several liability for the Obligations.

        (b) Each of the Borrowers, jointly and severally, hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a co-debtor, joint
and



<PAGE>   35
                                      -29-


several liability with the other Borrowers with respect to the payment and
performance of all of the Obligations (including, without limitation, any
Obligations arising under this Section 4.12), it being the intention of the
parties hereto that all of the Obligations shall be the joint and several
Obligations of each of the Borrowers without preferences or distinction among
them.

        (c) If and to the extent that any of the Borrowers shall fail to make
any payment with respect to any of the Obligations as and when due or to perform
any of the Obligations in accordance with the terms thereof, then in each such
event the other Borrowers will make such payment with respect to, or perform,
such Obligation.

        (d) The Obligations of each of the Borrowers under the provisions of
this Section 4.12 constitute full recourse Obligations of each of the Borrowers
enforceable against each such corporation to the full extent of its properties
and assets, irrespective of the validity, regularity or enforceability of this
Credit Agreement or any other circumstance whatsoever.

        (e) Except as otherwise expressly provided in this Credit Agreement,
each of the Borrowers hereby waives notice of acceptance of its joint and
several liability, notice of any Loans made under this Credit Agreement, notice
of any action at any time taken or omitted by the Banks under or in respect of
any of the Obligations, and, generally, to the extent permitted by applicable
law, all demands, notices and other formalities of every kind in connection with
this Credit Agreement. Each of the Borrowers hereby assents to, and waives
notice of, any extension or postponement of the time for the payment of any of
the Obligations, the acceptance of any payment of any of the Obligations, the
acceptance of any partial payment thereon, any waiver, consent or other action
or acquiescence by the Banks at any time or times in respect of any default by
any of the Borrowers in the performance or satisfaction of any term, covenant,
condition or provision of this Credit Agreement, any and all other indulgences
whatsoever by the Banks in respect of any of the Obligations, and the taking,
addition, substitution or release, in whole or in part, at any time or times, of
any security for any of the Obligations or the addition, substitution or
release, in whole or in part, of any of the Borrowers. Without limiting the
generality of the foregoing, each of the Borrowers assents to any other action
or delay in acting or failure to act on the part of the Banks with respect to
the failure by any of the Borrowers to comply with any of its respective
Obligations, including, without limitation, any failure strictly or diligently
to assert any right or to pursue any remedy or to comply fully with applicable
laws or regulations thereunder, which might, but for the provisions of this
Section 4.12, afford grounds for terminating, discharging or relieving any of
the Borrowers, in whole or in part, from any of its Obligations under this
Section 4.12, it being the intention of each of the Borrowers that, so long as
any of the Obligations hereunder remain unsatisfied, the Obligations of such
Borrowers under this Section 4.12 shall not be discharged except by performance
and then only to the extent



<PAGE>   36
                                      -30-



of such performance. The Obligations of each of the Borrowers under this Section
4.12 shall not be diminished or rendered unenforceable by any winding up,
reorganization, arrangement, liquidation, re-construction or similar proceeding
with respect to any of the Borrowers or the Banks. The joint and several
liability of the Borrowers hereunder shall continue in full force and effect
notwithstanding any absorption, merger, amalgamation or any other change
whatsoever in the name, membership, constitution or place of formation of any of
the Borrowers or the Banks.

        (f) The provisions of this Section 4.12 are made for the benefit of the
Banks and their successors and assigns, and may be enforced in good faith by
them from time to time against any or all of the Borrowers as often as the
occasion therefor may arise and without requirement on the part of the Banks
first to marshal any of their claims or to exercise any of their rights against
any other Borrower or to exhaust any remedies available to them against any
other Borrower or to resort to any other source or means of obtaining payment of
any of the Obligations hereunder or to elect any other remedy. The provisions of
this Section 4.12 shall remain in effect until all of the Obligations shall have
been paid in full or otherwise fully satisfied. If at any time, any payment, or
any part thereof, made in respect of any of the Obligations, is rescinded or
must otherwise be restored or returned by the Banks upon the insolvency,
bankruptcy or reorganization of any of the Borrowers, or otherwise, the
provisions of this Section 4.12 will forthwith be reinstated in effect, as
though such payment had not been made.

        Section 5. REPRESENTATIONS AND WARRANTIES. The Borrowers jointly and
severally represent and warrant to the Banks that on and as of the date of this
Credit Agreement, each Drawdown Date, and the date of issuance of any Letter of
Credit (with any disclosure on a schedule pursuant to this Section 5 applying to
all relevant representations and warranties, regardless of whether such schedule
is referenced in each relevant representation):

            Section 5.1.  CORPORATE AUTHORITY.

        (a) INCORPORATION; GOOD STANDING. Each Borrower (i) is a corporation
duly organized, validly existing and in good standing or in current status under
the laws of its respective state of incorporation, (ii) has all requisite
corporate power to own its property and conduct its business as now conducted
and as presently contemplated, and (iii) is in good standing as a foreign
corporation and is duly authorized to do business in each jurisdiction in which
its property or business as presently conducted or contemplated makes such
qualification necessary except where a failure to be so qualified would not have
a material adverse effect on the business, assets or financial condition of such
Borrower.

        (b) AUTHORIZATION. The execution, delivery and performance of the Loan
Documents and the transactions contemplated hereby and thereby (i) are within
the corporate authority of each Borrower, (ii) have been duly authorized by all

material breach or



<PAGE>   37
                                      -31-


contravention of any provision of law, statute, rule or regulation to which any
Borrower is subject or any judgment, order, writ, injunction, license or permit
applicable to any Borrower so as to materially adversely affect the assets,
business or any activity of the Borrowers, and (iv) do not conflict with any
provision of the corporate charter or bylaws of any Borrower or any agreement or
other instrument binding upon them.

        (c) ENFORCEABILITY. The execution, delivery and performance of the Loan
Documents will result in valid and legally binding obligations of the Borrowers
enforceable against each in accordance with the respective terms and provisions
hereof and thereof, except as enforceability is limited by bankruptcy,
insolvency, reorganization, moratorium or other laws relating to or affecting
generally the enforcement of creditors' rights and except to the extent that
availability of the remedy of specific performance or injunctive relief is
subject to the discretion of the court before which any proceeding therefor may
be brought.

        Section 5.2. GOVERNMENTAL APPROVALS. The execution, delivery and
performance by the Borrowers of the Loan Documents and the transactions
contemplated hereby and thereby do not require any approval or consent of, or
filing with, any governmental agency or authority other than those already

        Section 5.3. TITLE TO PROPERTIES; LEASES. The Borrowers own all of the
assets reflected in the consolidated balance sheets as at the Interim Balance
Sheet Date or acquired since that date (except property and assets sold or
otherwise disposed of in the ordinary course of business since that date),

consolidated financial statements of the Borrowers dated the Interim Balance
Sheet Date. Said financial statements have been prepared in accordance with GAAP
and fairly present in all material respects the financial condition of the
Borrowers on a consolidated basis, as at the close of business on the date
thereof and the results of operations for the period then ended. There are no
contingent liabilities of the Borrowers involving material amounts, known to the
officers of the Borrowers, which have not been disclosed in said balance sheets
and the related notes thereto or otherwise in writing to the Banks.

                     (b) The Borrowers on a consolidated basis (both before and
after giving effect to the transactions contemplated by this Credit Agreement)
are and will be solvent (i.e., they have assets having a fair value in excess of
the amount required to pay their probable liabilities on their existing debts as
they become absolute and



<PAGE>   38
                                      -32-



matured) and have, and expect to have, the ability to pay their debts from time
to time incurred in connection therewith as such debts mature.

        Section 5.5. NO MATERIAL CHANGES, ETC. Since the Interim Balance Sheet
Date, there have occurred no material adverse changes in the financial condition
or businesses of the Borrowers, taken as a whole, as shown on or reflected in
the consolidated balance sheet of the Borrowers as of the Interim Balance Sheet
Date, or the consolidated statement of income for the fiscal year then ended.
Since the Interim Balance Sheet Date, there have not been any Distributions
other than as permitted by Section 7.6 hereof.

        Section 5.6. PERMITS, FRANCHISES, PATENTS, COPYRIGHTS, ETC. Each
Borrower possess all franchises, patents, copyrights, trademarks, trade names,
licenses and permits, and rights in respect of the foregoing, adequate for the
conduct of their businesses substantially as now conducted without known
conflict with any rights of others.

        Section 5.7. LITIGATION. Except as shown on Schedules 5.7 and 5.16
hereto, there are no actions, suits, proceedings or investigations of any kind
pending or, to the knowledge of any Borrower, threatened against any Borrower
before any court, tribunal or administrative agency or board which, if adversely
determined, might, either in any individual case or in the aggregate, materially
adversely affect the properties, assets, financial condition or business of the
Borrowers, taken as a whole, or materially impair the right of the Borrowers,
taken as a whole, to carry on business substantially as now conducted, or result
in any substantial liability not adequately covered by insurance, or for which
adequate reserves are not maintained on the consolidated balance sheet or which
question the validity of any of the Loan Documents or any action taken or to be
taken pursuant hereto or thereto.

        Section 5.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. No Borrower is
subject to any charter, corporate or other legal restriction, or any judgment,
decree, order, rule or regulation which in the judgment of the Borrowers'
officers has or is expected in the future to have a materially adverse effect on
the business, assets or financial condition of the Borrowers, taken as a whole.
No Borrower is a party to any contract or agreement which in the judgment of the
Borrowers' officers has or is expected to have any materially adverse effect on
the business of the Borrowers, taken as a whole, except as otherwise reflected
in adequate reserves.

        Section 5.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. No Borrower
is violating any provision of its charter documents or by-laws or any agreement
or instrument by which any of them may be subject or by which any of them or any
of their properties may be bound or any decree, order, judgment, or any statute,
license, rule or regulation, in a manner which could result in the imposition of
substantial penalties or materially and adversely affect the financial
condition, properties or business of any Borrower. All Material Contracts (a
complete and accurate list of



<PAGE>   39
                                      -33-


which is attached hereto as Schedule 5.9) are in full force and effect, and no
default or event of default has occurred and is continuing under any Material
Contract.

        Section 5.10. TAX STATUS. Each Borrower has made or filed all federal
and state income and all other tax returns, reports and declarations required by
any jurisdiction to which any of them is subject (unless and only to the extent
that such Borrower has set aside on its books provisions reasonably adequate for
the payment of all unpaid and unreported taxes); and have paid all taxes and
other governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith; and have set aside on their books provisions
reasonably adequate for the payment of all taxes for periods subsequent to the
periods to which such returns, reports or declarations apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Borrowers know of no basis for any
such claim.

        Section 5.11. NO EVENT OF DEFAULT. No Default or Event of Default has
occurred and is continuing as of the date of this Credit Agreement.

        Section 5.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. No Borrower
is a "holding company," or a "subsidiary company" of a "holding company," or an
"affiliate" of a "holding company," as such terms are defined in the Public
Utility Holding Company Act of 1935; nor is any of them a "registered investment
company," or an "affiliated company" or a "principal underwriter" of a
"registered investment company," as such terms are defined in the Investment
Company Act of 1940, as amended.

        Section 5.13. ABSENCE OF FINANCING STATEMENTS, ETC. Other than Permitted
Liens and the liens of Imperial Bank and BFI to be discharged in accordance with
the payoff letters under Section 9.10, there is no financing statement, security
agreement, chattel mortgage, real estate mortgage or other document filed or
recorded with any filing records, registry, or other public office, which
purports to cover, affect or give notice of any present or possible future lien
on, or security interest in, any assets or property of any Borrower, or any
rights relating thereto.

        Section 5.14. EMPLOYEE BENEFIT PLANS.

        (a) Each Employee Benefit Plan and each Guaranteed Pension Plan has been
maintained and operated in compliance in all material respects with the
provisions of ERISA and, to the extent applicable, the Code, including but not
limited to the provisions thereunder respecting prohibited transactions and the
bonding of fiduciaries and other persons handling plan funds as required by
Section 412 of ERISA. Each Borrower has heretofore delivered to the Agent the
most recently completed annual report, Form 5500, with all required attachments,
and actuarial statement



<PAGE>   40
                                      -34-



required to be submitted under Section 103(d) of ERISA, with respect to each
Guaranteed Pension Plan.

        (b) No Employee Benefit Plan, which is an employee welfare benefit plan
within the meaning of Section 3(1) or Section 3(2)(B) of ERISA, provides benefit
coverage subsequent to termination of employment, except as required by Title I,
Part 6 of ERISA or the applicable state insurance laws. A Borrower may terminate
each such Plan at any time (or at any time subsequent to the expiration of any
applicable bargaining agreement) in the discretion of such Borrower without
liability to any Person other than for claims arising prior to termination.

        (c) Each contribution required to be made to a Guaranteed Pension Plan,
whether required to be made to avoid the incurrence of an accumulated funding
deficiency, the notice or lien provisions of Section 302(f) of ERISA, or
otherwise, has been timely made. No waiver of an accumulated funding deficiency
or extension of amortization periods has been received with respect to any
Guaranteed Pension Plan, and no Borrower nor any ERISA Affiliate is obligated to
or has posted security in connection with an amendment to a Guaranteed Pension
Plan pursuant to Section 307 of ERISA or Section 401(a)(29) of the Code. No
liability to the PBGC (other than required insurance premiums, all of which have
been paid) has been incurred by any Borrower or any ERISA Affiliate with respect
to any Guaranteed Pension Plan and there has not been any ERISA Reportable Event
(other than an ERISA Reportable Event as to which the requirement of 30 days
notice has been waived), or any other event or condition which presents a
material risk of termination of any Guaranteed Pension Plan by the PBGC. Based
on the latest valuation of each Guaranteed Pension Plan (which in each case
occurred within twelve months of the date of this representation), and on the
actuarial methods and assumptions employed for that valuation, the aggregate
benefit liabilities of all such Guaranteed Pension Plans within the meaning of
Section 4001 of ERISA did not exceed the aggregate value of the assets of all
such Guaranteed Pension Plans, disregarding for this purpose the benefit
liabilities and assets of any Guaranteed Pension Plan with assets in excess of
benefit liabilities.

        (d) No Borrower nor any ERISA Affiliate has incurred any material
liability (including secondary liability) to any Multiemployer Plan as a result
of a complete or partial withdrawal from such Multiemployer Plan under Section
4201 of ERISA or as a result of a sale of assets described in Section 4204 of
ERISA. No Borrower nor any ERISA Affiliate has been notified that any
Multiemployer Plan is in reorganization or insolvent under and within the
meaning of Section 4241 or Section 4245 of ERISA or is at risk of entering
reorganization or becoming insolvent, or that any Multiemployer Plan intends to
terminate or has been terminated under Section 4041A of ERISA.

        Section 5.15. USE OF PROCEEDS.

                      Section 5.15.1. GENERAL. The proceeds of the Loans shall
be used solely as follows: (a) to repay existing Indebtedness of the Borrowers;
(b) to finance



<PAGE>   41
                                      -35-



acquisitions permitted pursuant to Section 7.4; and (c) for capital
expenditures, working capital, and general corporate purposes.

                      Section 5.15.2. REGULATIONS U AND X. No portion of any
Loan is to be used, and no portion of any Letter of Credit is to be obtained,
for the purpose of purchasing or carrying any "margin security" or "margin
stock" as such terms are used in Regulations U and X of the Board of Governors
of the Federal Reserve System, 12 C.F.R. Parts 221 and 224.

                      Section 5.15.3. INELIGIBLE SECURITIES. No portion of the
proceeds of any Loans is to be used, and no portion of any Letter of Credit is
to be obtained, for the purpose of (a) knowingly purchasing, or providing credit
support for the purchase of, Ineligible Securities from a Section 20 Subsidiary
during any period in which such Section 20 Subsidiary makes a market in such
Ineligible Securities, (b) knowingly purchasing, or providing credit support for
the purchase of, during the underwriting or placement period, any Ineligible
Securities being underwritten or privately placed by a Section 20 Subsidiary, or
(c) making, or providing credit support for the making of, payments of principal
or interest on Ineligible Securities underwritten or privately placed by a
Section 20 Subsidiary and issued by or for the benefit of the Borrowers or other
Affiliate of the Borrowers.

        Section 5.16. ENVIRONMENTAL COMPLIANCE. Each Borrower has investigated
the past and present condition and usage of the Real Property and the operations
conducted thereon and, based upon such diligent investigation, has determined
that, except as shown on Schedule 5.16:

        (a) No Borrower, nor any operator of the Borrowers' properties, is in
violation, or alleged violation, of any judgment, decree, order, law, permit,
license, rule or regulation pertaining to environmental matters, including
without limitation, those arising under RCRA, CERCLA, the Superfund Amendments
and Reauthorization Act of 1986, the Federal Clean Water Act, the Federal Clean
Air Act, the Toxic Substances Control Act, or any state or local statute,
regulation, ordinance, order or decree relating to health, safety or the
environment (the "Environmental Laws"), which violation would have a material
adverse effect on the business, assets or financial condition of the Borrowers
on a consolidated basis.

        (b) No Borrower has received notice from any third party, including,
without limitation: any federal, state or local governmental authority, (i) that
any of the Borrowers has been identified by the United States Environmental
Protection Agency ("EPA") as a potentially responsible party under CERCLA with
respect to a site listed on the National Priorities List, 40 C.F.R. Part 300
Appendix B; (ii) that any hazardous waste, as defined by 42 U.S.C. Section
6903(5), any hazardous substances as defined by 42 U.S.C. Section 9601(14), any
pollutant or contaminant as defined by 42 U.S.C. Section 9601(33) or any toxic
substance, oil or hazardous materials or other chemicals or substances regulated
by any Environmental Laws ("Hazardous



<PAGE>   42
                                      -36-



Substances") which any of the Borrowers has generated, transported or disposed
of has been found at any site at which a federal, state or local agency or other
third party has conducted or has ordered that any Borrower conduct a remedial
investigation, removal or other response action pursuant to any Environmental
Law; or (iii) that it is or shall be a named party to any claim, action, cause
of action, complaint, legal or administrative proceeding arising out of any
third party's incurrence of costs, expenses, losses or damages of any kind
whatsoever in connection with the release of Hazardous Substances.

        (c) Except where it would not have a material adverse effect on the
value of the Real Property, (i) no portion of the Real Property has been used
for the handling, processing, storage or disposal of Hazardous Substances; and
no underground tank or other underground storage receptacle for Hazardous
Substances is located on such properties; (ii) in the course of any activities
conducted by the Borrowers, or operators of the Real Property, no Hazardous
Substances have been generated or are being used on such properties; (iii) there
have been no unpermitted Releases or threatened Releases of Hazardous Substances
on, upon, into or from the Real Property; (iv) to the best of the Borrowers'
knowledge, there have been no Releases on, upon, from or into any real property
in the vicinity of the Real Property which, through soil or groundwater
contamination, may have come to be located on such properties; and (v) in
addition, when required under applicable Environmental Laws, any Hazardous
Substances that have been generated on the Real Property have been transported
offsite only by carriers having an identification number issued by the EPA,
treated or disposed of only by treatment or disposal facilities maintaining
valid permits as required under applicable Environmental Laws, which
transporters and facilities, to the best of the Borrowers' knowledge, have been
and are operating in material compliance with such permits and applicable
Environmental Laws.

        (d) None of the Real Property is or shall be subject to any applicable
environmental clean-up responsibility law or environmental restrictive transfer
law or regulation, by virtue of the transactions set forth herein and
contemplated hereby.

        Section 5.17. PERFECTION OF SECURITY INTERESTS. All filings,
assignments, pledges and deposits of documents or instruments have been made and
all other actions have been taken that are necessary or advisable under
applicable law to establish and perfect the Agent's security interest in the
Collateral. The Collateral and the Agent's rights with respect to the Collateral
are not subject to any setoff, claims, withholdings or other defenses.

        Section 5.18. TRANSACTIONS WITH AFFILIATES. Except as disclosed in
Schedule 5.18 or filings made by the Borrowers under the Securities Exchange Act
of 1934 prior to the Closing Date, and except for arm's length transactions
pursuant to which a Borrower makes payments in the ordinary course of business
upon terms no less favorable than such Borrower could obtain from third parties,
none of the officers, directors, or employees of any Borrower is presently a
party to any transaction with another



<PAGE>   43
                                      -37-



Borrower (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of any Borrower, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

        Section 5.19. SUBSIDIARIES. Schedule 2 sets forth a complete and
accurate list of the Subsidiaries of the Parent, including the name of each
Subsidiary, the location of its chief executive office, and its jurisdiction of
incorporation, together with the number of authorized and outstanding shares of
each Subsidiary. Each Subsidiary listed on Schedule 2 is (a) wholly owned by the
Parent (other than W.C. International, which is wholly-owned by W.C. of
Washington) and (b) is a Borrower hereunder, 100% of the assets and stock of
which have been pledged to the Agent on behalf of the Banks pursuant to the
Security Documents. The Parent has good and marketable title to all of the
shares it purports to own of the stock of each such Subsidiary, and W.C. of
Washington has good and marketable title to all of the shares it purports to own
of the stock of W.C. International, free and clear in each case of any lien. All
such shares have been duly issued and are fully paid and non-assessable.

        Section 5.20. TRUE COPIES OF CHARTER AND OTHER DOCUMENTS. Each Borrower
has furnished the Agent copies, in each case true and complete as of the Closing
Date, of its (a) charter and other incorporation documents and (b) by-laws, each
including any amendments thereto.

        Section 5.21. DISCLOSURE. Neither this Credit Agreement, nor any of the
other Loan Documents, nor any document or information furnished by the Borrowers
in connection therewith contains any untrue statement of a material fact or
omits to state a material fact (known to any Borrower in the case of any
document or information not furnished by the Borrowers) necessary in order to
make the statements herein or therein not misleading. There is no fact known to
any Borrower which materially adversely affects, or which is reasonably likely
in the future to materially adversely affect, the business, assets, or financial
condition of any Borrower, exclusive of effects resulting from changes in
general economic conditions, legal standards or regulatory conditions.

        Section 5.22. CAPITALIZATION.

        (a) As of the Closing Date, the authorized capital stock of the Parent
consists of 15,000,000 shares of common stock (par value $0.01) per share) of
which 2,300,000 shares were outstanding as of the Closing Date and 10,000,000
shares of preferred stock (par value $0.01) of which 2,499,998 shares were
outstanding as of the Closing Date. All of such outstanding shares are fully
paid and non-assessable. In addition, as of the Closing Date, the Board of
Directors of the Parent has duly



<PAGE>   44
                                      -38-



reserved 1,451,000 shares of the Parent's common stock for issuance pursuant to
outstanding warrants, and has reserved 819,000 shares of the Parent's common
stock for issuance upon the exercise of employee stock options.

        (b) The shares of the capital stock of the Subsidiaries pledged to the
Agent pursuant to the Stock Pledge Agreements are held of record as set forth on
the respective Annex A to each Stock Pledge Agreement. Such capital stock
constitutes, of record, 100% of the outstanding capital stock of each such
Subsidiary, and, to our knowledge, on a fully-diluted basis, 100% of such
outstanding capital stock.

        Section 5.23. YEAR 2000 PROBLEM. The Borrowers have reviewed the areas
within their business and operations which could be adversely affected by, and
have developed or are developing a program to address on a timely basis, the
Year 2000 Problem. Based on such review and program, the Year 2000 Problem will
not have a material adverse effect on their business and operations.

        Section 6. AFFIRMATIVE COVENANTS OF THE BORROWERS. The Borrowers jointly
and severally covenant and agree that, so long as any Loan or Note is
outstanding or the Banks have any obligation to make Loans or the Agent has any
obligation to issue, extend, or renew any Letters of Credit hereunder:

        Section 6.1. PUNCTUAL PAYMENT. The Borrowers will duly and punctually
pay or cause to be paid the principal and interest on the Loans, all
Reimbursement Obligations, fees and other amounts provided for in this Credit
Agreement and the other Loan Documents, all in accordance with the terms of this
Credit Agreement and such other Loan Documents.

        Section 6.2. MAINTENANCE OF OFFICES. The Parent will maintain its chief
executive offices at 2260 Douglas Boulevard, Suite 280, Roseville, California
95661, and each Subsidiary will maintain its chief executive offices at the
location set forth on Schedule 2, or at such other place in the United States as
the Borrowers shall designate upon 30 days' prior written notice to the Agent.

        Section 6.3. RECORDS AND ACCOUNTS. Each Borrower will (i) keep true and
accurate records and books of account in which full, true and correct entries
will be made in accordance with generally accepted accounting principles, (ii)
maintain adequate accounts and reserves for all taxes (including income taxes),
depreciation, depletion, obsolescence and amortization of its properties,
contingencies, and other reserves, and (iii) at all times engage the Accountants
as the independent certified public accountants of the Borrowers.

        Section 6.4. FINANCIAL STATEMENTS, CERTIFICATES AND INFORMATION. The
Borrowers will deliver to the Banks:



<PAGE>   45
                                      -39-


        (a) as soon as practicable, but, in any event not later than 90 days
after the end of each fiscal year of the Borrowers, the consolidated and
consolidating balance sheets of the Borrowers as at the end of such year,
statements of cash flows, and the related consolidated and consolidating
statements of operations, each setting forth in comparative form the figures for
the previous fiscal year, all such consolidated and consolidating financial
statements to be in reasonable detail, prepared in accordance with GAAP and,
with respect to the consolidated financial statements, certified by the
Accountants. In addition, simultaneously therewith, the Borrowers shall use
reasonable efforts to provide the Banks with a written statement from the
Accountants to the effect that the Borrowers are in compliance with the
covenants set forth in Section 8 hereof, and that, in making the examination
necessary to said certification, nothing has come to the attention of the
Accountants that would indicate that any Default or Event of Default exists, or,
if the Accountants shall have obtained knowledge of any then existing Default or
Event of Default they shall disclose in such statement any such Default or Event
of Default; provided that the Accountants shall not be liable to the Banks for
failure to obtain knowledge of any Default or Event of Default;

        (b) as soon as practicable, but in any event not later than 45 days
after the end of each fiscal quarter of the Borrowers, copies of the
consolidated and consolidating balance sheets and statement of operations of the
Borrowers as at the end of such quarter, subject to year end adjustments, and
the related statement of cash flows, all in reasonable detail and prepared in
accordance with GAAP, with a certification by the principal financial or
accounting officer of the Borrowers (the "CFO") that the consolidated financial
statements are prepared in accordance with GAAP and fairly present the
consolidated financial condition of the Borrowers as at the close of business on
the date thereof and the results of operations for the period then ended;

        (c) as soon as practicable, but in any event within thirty (30) days
after the end of each month in each fiscal year of the Borrowers, unaudited
monthly consolidated and consolidating financial statements of the Borrowers for
such month, prepared in accordance with GAAP, with a certification by the CFO
that the information contained in such financial statements fairly presents the
financial condition of the Borrowers on the date thereof (subject to year-end
adjustments);

        (d) simultaneously with the delivery of the financial statements
referred to in (a) and (b) above, a statement in the form of Exhibit C hereto
(the "Compliance Certificate") certified by the CFO that the Borrowers are in
compliance with the covenants contained in Sections 6, 7 and 8 hereof as of the
end of the applicable period setting forth in reasonable detail computations
evidencing such compliance, provided that if the Borrowers shall at the time of
issuance of such certificate or at any other time obtain knowledge of any
Default or Event of Default, the Borrowers shall include in such certificate or
otherwise deliver forthwith to the Banks a certificate



<PAGE>   46
                                      -40-



specifying the nature and period of existence thereof and what action the
Borrowers propose to take with respect thereto and a certificate of the
Borrowers' Chief Operating Officer in the form attached hereto as Exhibit D with
respect to environmental matters;

        (e) contemporaneously with or promptly following the delivery thereof to
the boards of directors of the Borrowers, copies of the financial statements,
financial projections, annual budget, variance reports and business plan
concerning the Borrowers in substantially the same form in which such
information is supplied to the boards of directors of the Borrowers;

        (f) contemporaneously with, or promptly following, the filing or mailing
thereof, copies of all material of a financial nature filed with the Securities
and Exchange Commission or sent to the stockholders of the Borrowers; and

        (g) from time to time, such other financial data and other information
(including accountants' management letters) as the Banks may reasonably request.

        The Borrowers hereby authorize the Banks to disclose any information
obtained pursuant to this Credit Agreement to all appropriate governmental
regulatory authorities where required by law; provided, however, that this
authorization shall not be deemed to be a waiver of any rights to object to the
disclosure by the Banks of any such information which the Borrowers have or may
have under the federal Right to Financial Privacy Act of 1978, as in effect from
time to time.

        Section 6.5. CORPORATE EXISTENCE AND CONDUCT OF BUSINESS. Each Borrower
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence, corporate rights and franchises;
effect and maintain its foreign qualifications, licensing, domestication or
authorization except as terminated by such Borrower's Board of Directors in the
exercise of its reasonable judgment and except where the failure of a Borrower
to remain so qualified would not materially adversely impair the financial
condition of the Borrowers on a consolidated basis; use its best efforts to
comply with all applicable laws; and shall not become obligated under any
contract or binding arrangement which, at the time it was entered into would
materially adversely impair the financial condition of the Borrowers on a
consolidated basis. Each Borrower will continue to engage primarily in the
businesses now conducted by it and in related businesses.

        Section 6.6. MAINTENANCE OF PROPERTIES. The Borrowers will cause all
material properties used or useful in the conduct of their businesses to be
maintained and kept in good condition, repair and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Borrowers may be necessary so that the businesses carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this



<PAGE>   47
                                      -41-



section shall prevent the Borrowers from discontinuing the operation and
maintenance of any of their properties if such discontinuance is, in the
judgment of the Borrowers, desirable in the conduct of their business and which
does not in the aggregate materially adversely affect the businesses of the
Borrowers on a consolidated basis.

        Section 6.7. INSURANCE. The Borrowers will maintain with financially
sound and reputable insurance companies, funds or underwriters' insurance of the
kinds, covering the risks (other than risks arising out of or in any way
connected with personal liability of any officers and directors thereof) and in
the relative proportionate amounts usually carried by reasonable and prudent
companies conducting businesses similar to that of the Borrowers, but in no
event less than that required under Section 7 of the Security Agreement. In
addition, the Borrowers will furnish from time to time, upon the Agent's
request, a summary of the insurance coverage of each of the Borrowers, which
summary shall be in form and substance satisfactory to the Agent and, if
requested by the Agent, will furnish to the Agent copies of the applicable
policies.

        Section 6.8. TAXES. The Borrowers will duly pay and discharge, or cause
to be paid and discharged, before the same shall become overdue, all taxes,
assessments and other governmental charges (other than taxes, assessments and
other governmental charges imposed by foreign jurisdictions which in the
aggregate are not material to the business or assets of any Borrower on an
individual basis or of the Borrowers on a consolidated basis) imposed upon it
and its real properties, sales and activities, or any material part thereof, or
upon the income or profits therefrom, as well as all claims for labor,
materials, or supplies, which if unpaid might by law become a lien or charge
upon any material portion of its property, unless such lien is a Permitted Lien;
provided, however, that any such tax, assessment, charge, levy or claim need not
be paid if the validity or amount thereof shall currently be contested in good
faith by appropriate proceedings and if such Borrower shall have set aside on
its books adequate reserves with respect thereto; and provided, further, that
the Borrowers will pay all such taxes, assessments, charges, levies or claims
forthwith upon the commencement of proceedings to foreclose any lien which may
have attached as security therefor.

        Section 6.9. INSPECTION OF PROPERTIES, BOOKS, AND CONTRACTS. The
Borrowers will permit the Banks, the Agent or any of their designated
representatives, upon reasonable notice and during normal business hours, to
visit and inspect any of their properties, to examine their books of account
(including the making of periodic accounts receivable reviews), or contracts
(and to make copies thereof and extracts therefrom), and to discuss their
affairs, finances and accounts with, and to be advised as to the same by, their
officers, all at such times and intervals as the Banks may reasonably request.

        Section 6.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES AND PERMITS;
MAINTENANCE OF MATERIAL LICENSES AND PERMITS. The Borrowers will (i) comply



<PAGE>   48
                                      -42-



with the provisions of their charter documents and by-laws and all agreements
and instruments by which they or any of their properties may be bound; and (ii)
comply with all applicable laws and regulations (including Environmental Laws),
decrees, orders, judgments, licenses and permits, including, without limitation,
all environmental permits hereto ("Applicable Laws"), except where noncompliance
with such Applicable Laws would not have a material adverse effect in the
aggregate on the consolidated financial condition, properties or businesses of
the Borrowers. If at any time while the Notes, or any Loan or Letter of Credit
is outstanding or any Bank or the Agent has any obligation to make Loans or
issue Letters of Credit hereunder, any authorization, consent, approval, permit
or license from any officer, agency or instrumentality of any government shall
become necessary or required in order that the Borrowers may fulfill any of
their obligations hereunder, the Borrowers will immediately take or cause to be
taken all reasonable steps within the power of the Borrowers to obtain such
authorization, consent, approval, permit or license and furnish the Banks with
evidence thereof.

        Section 6.11. ENVIRONMENTAL INDEMNIFICATION. Each Borrower covenants and
agrees that it will indemnify and hold the Banks harmless from and against any
and all claims, expense, damage, loss or liability incurred by the Banks
(including all costs of legal representation incurred by the Banks) relating to
(a) any release or threatened release of hazardous substances on the Real
Property; (b) any violation of any Environmental Laws with respect to conditions
at the Real Property or the operations conducted thereon; or (c) the
investigation or remediation of offsite locations at which any Borrower or its
predecessors are alleged to have directly or indirectly disposed of hazardous
substances. It is expressly acknowledged by each Borrower that this covenant of
indemnification shall include claims, expense, damage, loss or liability
incurred by the Banks based upon the Banks' negligence, and this covenant shall
survive any foreclosure or any modification, release or discharge of the Loan
Documents or the payment of the Loans and shall inure to the benefit of the
Banks, their successors and assigns.

        Section 6.12. FURTHER ASSURANCES. The Borrowers will cooperate with the
Banks and execute such further instruments and documents as the Banks shall
reasonably request to carry out to the Banks' satisfaction the transactions
contemplated by this Credit Agreement and the Loan Documents.

        Section 6.13. NOTICE OF POTENTIAL CLAIMS OR LITIGATION. The Borrowers
will deliver to the Banks, within 30 days of receipt thereof, written notice of
the initiation of any action, claim, complaint, or any other notice of dispute
or potential litigation (including without limitation any alleged violation of
any Environmental Law), wherein the potential liability is in excess of
$150,000, together with a copy of each such notice received by any Borrower.



<PAGE>   49
                                      -43-



        Section 6.14. NOTICE OF CERTAIN EVENTS CONCERNING INSURANCE AND
ENVIRONMENTAL CLAIMS.

                      (a) The Borrowers will provide the Banks with written
notice as to any material cancellation or material change in any insurance of
the Borrowers within ten (10) Business Days after the Borrowers' receipt of any
notice (whether formal or informal) of such cancellation or change by any of
their insurers.

                      (b) The Borrowers will promptly notify the Banks in
writing of any of the following events:

                          (i) upon any Borrower obtaining knowledge of any
violation of any Environmental Law regarding the Real Property or any Borrower's
operations, which violation could have a material adverse effect on the Real
Property or on such Borrower's operations; (ii) upon any Borrower obtaining
knowledge of any potential or known Release or threat of Release of any
Hazardous Substance at, from, or into the Real Property which any Borrower
reports in writing or is reportable by it in writing to any governmental
authority and which is material in amount or nature or which could materially
affect the value of the Real Property; (iii) upon any Borrower's receipt of any
notice of violation of any Environmental Laws or of any Release or threatened
Release of Hazardous Substances, including a notice or claim of liability or
potential responsibility from any third party (including without limitation any
federal, state or local governmental officials) and including notice of any
formal inquiry, proceeding, demand, investigation or other action with regard to
(A) any Borrower's or any Person's operation of the Real Property, (B)
contamination on, from or into the Real Property, or (C) investigation or
remediation of offsite locations at which any Borrower or any of its
predecessors is alleged to have directly or indirectly Disposed of Hazardous
Substances, which violation or Release in any such case could have a material
adverse effect on the Real Property or on any Borrower's operations; or (iv)
upon any Borrower obtaining knowledge that any material expense or loss has been
incurred by such governmental authority in connection with the assessment,
containment, removal or remediation of any Hazardous Substances with respect to
which any Borrower may be liable or for which a lien may be imposed on the Real
Property.

        Section 6.15. RESPONSE ACTIONS. The Borrowers covenant and agree that if
any Release or Disposal of Hazardous Substances shall occur or shall have
occurred on the Real Property, the Borrowers will cause the prompt containment
and removal of such Hazardous Substances and remediation of the Real Property as
necessary to comply with all Environmental Laws or to preserve the value of the
Real Property.

        Section 6.16. ENVIRONMENTAL ASSESSMENTS. If the Banks in their good
faith judgment, after discussion with the Borrowers, have reason to believe that
the environmental condition of the Real Property has deteriorated, after
reasonable notice by the Banks, whether or not an Event of Default shall have

covenant or agreement contained in any agreement by which it is bound,
evidencing or securing borrowed money in an aggregate amount greater than
$250,000 for such period of time as would, or would have permitted (assuming the
giving of appropriate notice if required) the holder or holders thereof or of
any obligations issued thereunder to accelerate the maturity thereof, unless the
same shall have been waived by the holder(s) thereof; or

        (h) if any Borrower makes an assignment for the benefit of creditors, or

                                      -57-



application shall not have been dismissed within sixty (60) days following the

approving a petition in any such case or other proceeding, or a decree or order
for relief is entered in respect of any Borrower in an involuntary case under
federal bankruptcy laws as now or hereafter constituted;

        (j) if there shall remain in force, undischarged, unsatisfied and
unstayed, for more than thirty (30) days, whether or not consecutive, any final

account any undisputed insurance coverage;

        (k) any Borrower or any ERISA Affiliate incurs any liability to the PBGC

occurs with respect to a Guaranteed Pension Plan: (i) an ERISA Reportable Event,
or a failure to make a required installment or other payment (within the meaning
of Section 302(f)(1) of ERISA), provided that the Agent determines in its
reasonable discretion that such event (A) could be expected to result in
liability of any Borrower to the PBGC or such Guaranteed Pension Plan in an
aggregate amount exceeding $250,000 and (B) could constitute grounds for the
termination of such Guaranteed Pension Plan by the PBGC, for the appointment by

other legal proceeding to cancel, revoke or rescind any of the Loan Documents
shall be commenced by or on behalf of any Borrower or any stockholder of any
Borrower who is an officer or director of such Borrower, or any court or any

shall make a determination that, or issue a judgment, order, decree or ruling to
the effect that, any one or more of the Loan Documents is illegal, invalid or
unenforceable in accordance with the terms thereof;



<PAGE>   64
                                      -58-


        (m) (i) the Parent shall at any time, legally or beneficially own less
than one hundred percent (100%) of the shares of the capital stock of each other
Borrower (indirectly through W.C. of Washington in the case of W.C.
International), as adjusted pursuant to any stock split, stock dividend or
recapitalization or reclassification of the capital of such Borrower; or (ii)
any person or group of persons (within the meaning of Section 13 or 14 of the
Securities Exchange Act of 1934, as amended) other than existing shareholders of
the Parent as of the Closing Date shall have acquired beneficial ownership
(within the meaning of Rule 13d-3 promulgated by the Securities and Exchange
Commission under said Act) of 20% or more of the outstanding shares of common
stock of the Parent; or, during any period of twelve consecutive calendar
months, individuals who were directors of the Parent on the first day of such
period shall cease to constitute a majority of the board of directors; provided,
however, that any such change of control resulting from an acquisition permitted
under Section 7.4 shall not constitute a Default or an Event of Default
hereunder, and provided further, that any change in the composition of the board
of directors of the Parent which occurs between the Closing Date and April 1,
1998 with the approval of Ron J. Mittelstaedt shall not constitute a Default or
an Event of Default hereunder; or

        (n) the early termination or cancellation of, or any material default by
a Borrower under, any Material Contract;

then, and in any such event, so long as the same may be continuing, the Agent
may, and at the request of the Majority Banks shall, by notice in writing to the
Borrowers, declare all amounts owing with respect to this Credit Agreement, the
Notes and the other Loan Documents and all Reimbursement Obligations to be, and
they shall thereupon forthwith become, immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by the Borrowers; provided that in the event of any
Event of Default specified in Sections 12.1(h) or 12.1(i), all such amounts
shall become immediately due and payable automatically and without any
requirement of notice from the Agent or any Bank. Upon demand by the Banks after
the occurrence of any Event of Default, the Borrowers shall immediately provide
to the Agent cash in an amount equal to the Maximum Drawing Amount, to be held
by the Agent as collateral security for the Obligations, provided that in the
event of any Event of Default specified in Sections 12.1(h) or 12.1(i), all such
amounts shall become immediately due and payable automatically and without any
requirement of notice from the Agent or any Bank.

        Section 12.2. TERMINATION OF COMMITMENTS. If any Event of Default shall
occur, the Agent may, and at the request of the Majority Banks shall, by notice
to the Borrowers, terminate the unused portion of the Total Commitment
hereunder, and upon such notice being given, such unused portion of the Total
Commitment hereunder shall terminate immediately and the Banks shall be relieved
of all further obligations to make Loans to or issue Letters of Credit for the
account of the Borrowers hereunder, provided that in the event of any Event of
Default specified in



<PAGE>   65
                                      -59-


Sections 12.1(h) or 12.1(i), all such amounts shall become immediately due and
payable automatically and without any requirement of notice from the Agent or
any Bank. No termination of any portion of the Total Commitment hereunder shall
relieve the Borrowers of any of their existing Obligations to the Banks
hereunder or elsewhere.

        Section 12.3. REMEDIES. Subject to Section 13, in case any one or more
Events of Default shall have occurred and be continuing, and whether or not the
Banks shall have accelerated the maturity of the Loans pursuant to Section 12.1,
each Bank, if owed any amount with respect to the Loans or the Reimbursement
Obligations, may, with the consent of the Majority Banks but not otherwise, and
if the Agent shall have received opinions of nationally recognized law firms
specializing in California law, Louisiana law, and the law of any other state,
as applicable, having a one form of action rule to the effect that actions by
such Bank under such circumstances shall not constitute an action for purposes
of such state's one form of action rule or in any other way impair the
Collateral or the other Banks' rights hereunder or under the other Loan
Documents, proceed to protect and enforce its rights by suit in equity, action
at law or other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Credit Agreement and the other Loan
Documents or any instrument pursuant to which the Obligations to such Bank are
evidenced, including, without limitation, as permitted by applicable law the
obtaining of the ex parte appointment of a receiver, and, if such amount shall
have become due, by declaration or otherwise, proceed to enforce the payment
thereof or any legal or equitable right of such Bank. No remedy herein conferred
upon any Bank or the Agent or the holder of any Note or purchaser of any Letter
of Credit Participation is intended to be exclusive of any other remedy and each
and every remedy shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law or in equity or by
statute or any other provision of law.

        Section 13. SETOFF. Regardless of the adequacy of any collateral, during
the continuance of an Event of Default, any deposits or other sums credited by
or due from any Bank to the Borrowers and any securities or other property of
the Borrowers in the possession of such Bank may be applied to or set off
against the payment of the Obligations and any and all other liabilities, direct
or indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrowers to the Banks. The Banks agree among
themselves that, if a Bank shall obtain payment on any Obligation outstanding
under this Credit Agreement through the exercise of a right of offset, banker's
lien or counterclaim, or from any other source including under Section 12.3
(other than by way of a pro rata payment under this Credit Agreement), it shall
promptly make such adjustments with the other Banks as shall be equitable to the
end that all the Banks shall share the benefits of such payments pro rata in
accordance with the aggregate unpaid amount of the Revolving Credit Notes held
by each Bank immediately prior to the payment obtained by such Bank as
aforesaid. The Banks further agree among themselves that if any payment to a
Bank obtained by such Bank through the exercise of a right of offset, banker's
lien 


<PAGE>   66
                                      -60-



or counterclaim, or from any other source (other than by way of a pro rata
payment) as aforesaid shall be rescinded or must otherwise be restored, the
Banks who shall have shared the benefit of such payment shall return their share
of that benefit to the Bank whose payment shall have been rescinded or otherwise
restored.

        Section 14. THE AGENT.

        Section 14.1. APPOINTMENT OF AGENT, POWERS AND IMMUNITIES. Each Bank
hereby irrevocably appoints and authorizes the Agent to act as its agent
hereunder and under the other Loan Documents, provided, however, the Agent is
hereby authorized to serve only as an administrative and collateral agent for
the Banks and to exercise such powers as are reasonably incidental thereto and
as are set forth in this Credit Agreement and the other Loan Documents. The
Agent hereby acknowledges that it does not have the authority to negotiate any
agreement which would bind the Banks or agree to any amendment, waiver or
modification of any of the Loan Documents or bind the Banks except as set forth
in this Credit Agreement or the Loan Documents. Except as provided in this
Section 14 and in the other Loan Documents, the Agent shall take action or
refrain from acting only upon instructions of the Banks and no action taken or
failure to act without the consent of the Banks shall be binding on any Bank
which has not consented. Each Bank irrevocably authorizes the Agent to execute
the Security Documents and all other instruments relating thereto and to take
such action on behalf of each of the Banks and to exercise all such powers as
are expressly delegated to the Agent under the Loan Documents and all related
documents, together with such other powers as are reasonably incidental thereto.
It is agreed that the duties, rights, privileges and immunities of BKB, in its
capacity as issuer of Letters of Credit hereunder, shall be identical to its
duties, rights, privileges and immunities as a Bank as provided in this Section
14. The Agent shall not have any duties or responsibilities or any fiduciary
relationship with any Bank except those expressly set forth in this Credit
Agreement. Neither the Agent nor any of its affiliates shall be responsible to
the Banks for any recitals, statements, representations or warranties made by
the Borrowers or any other Person whether contained herein or otherwise or for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Credit Agreement, the other Loan Documents or any other document
referred to or provided for herein or therein or for any failure by the
Borrowers or any other Person to perform its obligations hereunder or thereunder
or in respect of the Notes. The Agent may employ agents and attorneys-in-fact
and shall not be responsible for the negligence or misconduct of any such agents
or attorneys-in-fact selected by it with reasonable care. The Agent shall
exercise the same care in administering the Loans as it exercises with respect
to similar transactions entered into solely for its own account; however,
neither the Agent nor any of its directors, officers, employees or agents shall
be responsible for any action taken or omitted to be taken in good faith by it
or them hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct. The Bank in its separate capacity as a Bank
shall have the same rights and powers hereunder as any other Bank.



<PAGE>   67
                                      -61-



        Section 14.2. ACTIONS BY AGENT. The Agent shall be fully justified in
failing or refusing to take any action under this Credit Agreement as it
reasonably deems appropriate unless it shall first have received such advice or
concurrence of the Banks and shall be indemnified to its reasonable satisfaction
by the Banks against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this
Credit Agreement or any of the Loan Documents in accordance with a request of
the Majority Banks, and such request and any action taken or failure to act
pursuant thereto shall be binding upon the Banks and all future holders of the
Notes or any Letter of Credit Participation.

        Section 14.3. INDEMNIFICATION. Without limiting the obligations of the
Borrowers under this Credit Agreement or any other Loan Document, the Banks
ratably agree hereby to indemnify and hold harmless the Agent, the Arranger, and
their affiliates from and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses (including any
expenses for which the Agent, the Arranger or such affiliate has not been
reimbursed by the Borrowers as required by Section 15), and liabilities of every
nature and character arising out of or related to this Credit Agreement, the
Notes, or any of the other Loan Documents or the transactions contemplated or
evidenced hereby or thereby, or the Agent's actions taken hereunder or
thereunder, except to the extent that any of the same shall be directly caused
by the Agent's willful misconduct or gross negligence, it being the intent of
the parties hereto that all such indemnified parties shall be indemnified for
their ordinary sole or contributory negligence.

        Section 14.4. REIMBURSEMENT. Without limiting the provisions of Section
14.3, the Banks and the Agent hereby agree that the Agent shall not be obliged
to make available to any Person any sum which the Agent is expecting to receive
for the account of that Person until the Agent has determined that it has
received that sum. The Agent may, however, disburse funds prior to determining
that the sums which the Agent expects to receive have been finally and
unconditionally paid to the Agent, if the Agent wishes to do so. If and to the
extent that the Agent does disburse funds and it later becomes known that the
Agent did not then receive a payment in an amount equal to the sum paid out,
then any Person to whom the Agent made the funds available shall, on demand from
the Agent, refund to the Agent the sum paid to that Person. If, in the opinion
of the Agent, the distribution of any amount received by it in such capacity
hereunder or under the Loan Documents might involve it in liability, it may
refrain from making distribution until its right to make distribution shall have
been adjudicated by a court of competent jurisdiction. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the Agent
is to be repaid, each Person to whom any such distribution shall have been made
shall either repay to the Agent its proportionate share of the amount so
adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such court.

        Section 14.5. DOCUMENTS.

                      Section 14.5.1 CLOSING DOCUMENTATION. Section 14.5.1.
CLOSING DOCUMENTATION. For purposes of determining compliance with the
conditions set forth in Section 9, each Bank that has executed this Credit
Agreement shall be deemed to have consented to, approved or accepted, or to be
satisfied with, each document and matter either sent, or made available, by the
Agent or the Arranger to such Bank for consent, approval, acceptance or
satisfaction, or required thereunder to be consented to or approved by or
acceptable or satisfactory to such Bank, unless the Agent shall have received
notice from such Bank prior to the Closing Date specifying such Bank's objection
thereto and such objection shall not have been withdrawn by notice to the Agent
to such effect on or prior to the Closing Date.

                      Section 14.5.2. OTHER DOCUMENTS. The Agent will forward to
each Bank, promptly after the Agent's receipt thereof, a copy of each notice or
other document furnished to the Agent for such Bank hereunder; provided,
however, that notwithstanding the foregoing, the Agent may furnish to the Banks
a monthly summary with respect to Letters of Credit issued hereunder in lieu of
copies of the related Letter of Credit Applications.

        Section 14.6. NON-RELIANCE ON AGENT AND OTHER BANKS. Each Bank
represents that it has, independently and without reliance on the Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of the financial condition and affairs of
the Borrowers and decision to enter into this Credit Agreement and the other
Loan Documents and agrees that it will, independently and without reliance upon
the Agent or any other Bank, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own appraisals and
decisions in taking or not taking action under this Credit Agreement or any
other Loan Document. The Agent shall not be required to keep informed as to the
performance or observance by the Borrowers of this Credit Agreement, the other
Loan Documents or any other document referred to or provided for herein or
therein or by any other Person of any other agreement or to make inquiry of, or
to inspect the properties or books of, any Person. Except for notices, reports
and other documents and information expressly required to be furnished to the
Banks by the Agent hereunder, the Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning any person which may come into the possession of the Agent or any of
its affiliates. Each Bank shall have access to all documents relating to the
Agent's performance of its duties hereunder at such Bank's request. Unless any
Bank shall promptly object to any action taken by the Agent hereunder (other
than actions to which the provisions of Section 14.8 are applicable and other
than actions which constitute gross negligence or willful misconduct by the
Agent), such Bank shall conclusively be presumed to have approved the same.

        Section 14.7. RESIGNATION OR REMOVAL OF AGENT. The Agent may resign at
any time by giving 60 days' prior written notice thereof to the Banks and the
Borrowers. Upon



<PAGE>   69
                                      -63-



any such resignation, the Banks shall have the right to appoint a successor
Agent. If no successor Agent shall have been so appointed by the Banks (and,
provided that no Default or Event of Default shall have occurred and be
continuing, approved by the Borrowers, such approval not to be unreasonably
withheld) and shall have accepted such appointment within 30 days after the
retiring Agent's giving of notice of resignation, then the retiring Agent may,
on behalf of the Banks, appoint a successor Agent, which shall be a financial
institution having a combined capital and surplus in excess of $150,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation, the provisions of this Credit Agreement shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent. Any new Agent appointed pursuant to
this Section 14.7 shall immediately issue new Letters of Credit in place of
Letters of Credit previously issued by the Agent (to the extent such Letters of
Credit are returned by the beneficiaries for purposes of such exchange).

        Section 14.8. CONSENTS, AMENDMENTS, WAIVERS, ETC. Any consent or
approval required or permitted by this Credit Agreement to be given by the Banks
may be given, and any term of this Credit Agreement, the other Loan Documents or
any other instrument related hereto or mentioned herein may be amended, and the
performance or observance by the Borrowers of any terms of this Credit
Agreement, the other Loan Documents or such other instrument or the continuance
of any Default or Event of Default may be waived (either generally or in a
particular instance and either retroactively or prospectively) with, but only
with, the written consent of the Borrowers and the written consent of the
Majority Banks, provided however, that the Agent may, in its reasonable
discretion, release Collateral with an aggregate value of $500,000 or less in
any calendar year. Notwithstanding the foregoing, no amendment, waiver or
consent shall do any of the following unless in writing and signed by the
Borrowers and each of the Banks affected thereby: (a) increase the Commitments
of the Banks or subject any Bank to any additional obligations, or (b) reduce
the principal of or the rate of interest on the Notes (including, without
limitation, interest on overdue amounts) or any fees payable hereunder; and
FURTHER, no amendment, waiver or consent shall do any of the following unless in
writing and signed by ALL of the Banks: (c) postpone the Maturity Date or any
date fixed for any payment in respect of principal or interest (including,
without limitation, interest on overdue amounts) on the Notes, (d) change the
definition of "Majority Banks" or the number of Banks which shall be required
for the Banks or any of them to take any action under the Loan Documents; (e)
amend this Section 14.8 or Section 18; (f) release any Collateral with an
aggregate value exceeding $500,000 in any calendar year or (g) release any
Borrower from its obligations hereunder.



<PAGE>   70
                                      -64-



        No waiver shall extend to or affect any obligation not expressly waived
or impair any right consequent thereon. No course of dealing or delay or
omission on the part of the Agent or any Bank in exercising any right shall
operate as a waiver thereof or otherwise be prejudicial thereto. No notice to or
demand upon the Borrowers shall entitle the Borrowers to other or further notice
or demand in similar or other circumstances.

        Section 14.9. DELINQUENT BANKS. Notwithstanding anything to the contrary
contained in this Credit Agreement or any of the other Loan Documents, any Bank
that fails (i) to make available to the Agent its pro rata share of any Loan or
to purchase any Letter of Credit Participation or (ii) to comply with the
provisions of Section 13 with respect to making dispositions and arrangements
with the other Banks, where such Bank's share of any payment received, whether
by setoff or otherwise, is in excess of its pro rata share of such payments due
and payable to all of the Banks, in each case as, when and to the full extent
required by the provisions of this Credit Agreement, shall be deemed delinquent
(a "Delinquent Bank") and shall be deemed a Delinquent Bank until such time as
such delinquency is satisfied. A Delinquent Bank shall be deemed to have
assigned any and all payments due to it from the Borrowers, whether on account
of outstanding Loans, Reimbursement Obligations, interest, fees or otherwise, to
the remaining nondelinquent Banks for application to, and reduction of, their
respective pro rata shares of all outstanding Loans and Reimbursement
Obligations. The Delinquent Bank hereby authorizes the Agent to distribute such
payments to the nondelinquent Banks in proportion to their respective pro rata
shares of all outstanding Loans and Reimbursement Obligations. A Delinquent Bank
shall be deemed to have satisfied in full a delinquency when and if, as a result
of application of the assigned payments to all outstanding Loans and
Reimbursement Obligations of the nondelinquent Banks, the Banks' respective pro
rata shares of all outstanding Loans and Reimbursement Obligations have returned
to those in effect immediately prior to such delinquency and without giving
effect to the nonpayment causing such delinquency.

        Section 15. EXPENSES AND INDEMNIFICATION.

        Section 15.1. EXPENSES. Whether or not the transactions contemplated
herein shall be consummated, the Borrowers agree to pay (i) the reasonable costs

claims, actions and suits whether groundless or otherwise, and from and against
any and all liabilities, losses, damages and expenses of every nature and
character arising out of this Credit Agreement or any of the other Loan
Documents or the transactions contemplated hereby including, without limitation,
(i) any actual or proposed use by the Borrowers of the proceeds of any of the
Loans or Letters of Credit, (ii) the Borrowers entering into or performing this
Credit Agreement or any of the other Loan Documents or (iii) with respect to the
Borrowers and their respective properties and assets, the violation of any
Environmental Law, the presence, disposal, escape, seepage, leakage, spillage,
discharge, emission, release or threatened release of any Hazardous Substances
or any action, suit, proceeding or investigation brought or threatened with
respect to any Hazardous Substances (including, but not limited to, claims with

indemnity, the Borrowers agree to pay promptly the reasonable fees and expenses
of such counsel. If, and to the extent that the obligations of the Borrowers

agree to make the maximum contribution to the payment in satisfaction of such
obligations which is permissible under applicable law.

        Section 15.3. SURVIVAL. The covenants contained in this Section 15 shall
survive payment or satisfaction in full of all other Obligations.

        Section 16. SURVIVAL OF COVENANTS, ETC. Unless otherwise stated herein,
all covenants, agreements, representations and warranties made herein, in the
other Loan Documents or in any documents or other papers delivered by or on
behalf of the Borrowers pursuant hereto shall be deemed to have been relied upon
by the Banks and the Agent, notwithstanding any investigation heretofore or
hereafter made by any of them, and shall survive the making by the Banks of the
Loans and the issuance, extension or renewal of any Letters of Credit, as herein
contemplated, and shall continue in full force and effect so long as any amount
due under this Credit Agreement, any Letter of Credit or the Notes remains
outstanding and unpaid or any Bank has any obligation to make any Loans or issue
any Letters of Credit hereunder. All statements contained in any certificate or
other paper delivered by or on behalf of the Borrowers pursuant hereto or in
connection with the transactions contemplated hereby shall constitute
representations and warranties by the Borrowers hereunder.

        Section 17. ASSIGNMENT AND PARTICIPATION. It is understood and agreed
that each Bank shall have the right to assign or participate at any time all or
a portion of its Commitment and interests in the risk relating to any Loans and
outstanding Letters of Credit hereunder in an amount equal to or greater than
$5,000,000 (which assignment shall be of an equal percentage of such Bank's
Commitment, the Revolving Credit Loans and outstanding Letters of Credit) to
Eligible Assignees with the prior written consent of the Agent and, unless a
Default or an Event of Default shall have occurred and be continuing, the
Borrowers, which approvals shall not be unreasonably withheld. It is further
agreed that each Eligible Assignee which executes and delivers to the Banks and
the Borrowers an Assignment and Acceptance in substantially the form of Exhibit
E (an "Assignment and Acceptance") shall, on the date specified in such
Assignment and Acceptance, become a party to this Credit Agreement and the other
Loan Documents for all purposes of this Credit Agreement and the other Loan
Documents, and its Commitment shall be as set forth in such Assignment and
Acceptance. Upon the execution and delivery of such Assignment and Acceptance
and payment by the assigning bank of an assignment fee in the amount of $3,500
to the Agent, (a) the Borrowers shall issue to such Eligible Assignee a
Revolving Credit Note in the amount of such Eligible Assignee's Commitment dated
the Closing Date or such other date as may be specified by the Agent and
otherwise completed in substantially the form of Exhibit A hereto and, to the
extent any assigning Bank has retained a portion of its obligations hereunder, a
replacement Revolving Credit Note to the assigning Bank; (b) the Agent shall
distribute to the Borrowers, the Banks and such Eligible Assignee a schedule
reflecting such changes; (c) this Credit Agreement shall be appropriately
amended to reflect (i) the status of such Eligible Assignee as a party hereto
and (ii) the status and rights of the Banks and Agent hereunder; and (d) the
Borrowers shall take such action as the Agent may reasonably request to perfect
any security interests in favor of the Banks, including any Eligible Assignee



<PAGE>   73
                                      -67-



which becomes a party to this Credit Agreement. The documents evidencing any
such participation may provide that, except with the consent of the bank or
financial institution that is a party thereto, such Bank will not consent to (a)
the reduction in or forgiveness of the stated principal of or rate of interest
on or Commitment Fee with respect to the portion of any Loan subject to such
participation or assignment, (b) the extension or postponement of any stated
date fixed for payment of principal or interest or Commitment Fee with respect
to the portion of any Loan subject to such participation or assignment, or (c)
the waiver or reduction of any right to indemnification of such Bank hereunder.
Notwithstanding the foregoing, no syndication or participation shall operate to
increase the Total Commitment hereunder or otherwise alter the substantive terms
of this Credit Agreement. Anything contained in this Section 17 to the contrary
notwithstanding, any Bank may at any time pledge all or any portion of its
interest and rights under this Credit Agreement (including all or any portion of
its Notes) to any of the twelve Federal Reserve Banks organized under Section 4
of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or the
enforcement thereof shall release the pledgor Bank from its obligations
hereunder or under any of the other Loan Documents.

        Section 18. PARTIES IN INTEREST. All the terms of this Credit Agreement
and the other Loan Documents shall be binding upon and inure to the benefit of

Credit Agreement, all notices and other communications made or required to be

share with the Agent and each Bank any information delivered to such Section 20
Subsidiary by the Borrowers, and (b) the Agent and each Bank to share with such

participant (or prospective assignee or participant) so long as such assignee or
participant agrees to be bound by the provisions of this Section 20.


                    Section 20.3. PRIOR NOTIFICATION. Unless specifically
prohibited by applicable law or court order, each of the Banks and the Agent

<PAGE>   75
                                      -69-

request in connection with an examination of the financial condition of such
Bank by such governmental agency) or pursuant to legal process.


                    Section 20.4. OTHER. In no event shall any Bank or the Agent
be obligated or required to return any materials furnished to it or any Section
20 Subsidiary by the Borrowers. The obligations of each Bank under this Section
20 shall supersede and replace the obligations of such Bank under any
confidentiality letter in respect of this financing signed and delivered by such
Bank to the Borrowers prior to the date hereof and shall be binding upon any
assignee of, or purchaser of any participation in, any interest in any of the
Loans or Reimbursement Obligations from any Bank.

right consequent thereon. No course of dealing or omission on the part of the
Agent or any Bank in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto. No notice to or demand upon the Borrowers
shall entitle the Borrowers to other or further notice or demand in similar or
other circumstances.

terminates, expires or is cancelled without having been exercised in full, the
Stock not purchased under such Option shall revert to and again become available
for issuance under the Plan.

4.    ADMINISTRATION.

      (a)   The Plan shall be administered by the Board or, at the election of
the Board, by a Committee, as provided in subsection (b). Subject to the Plan,

Agreement in a manner and to the extent it deems necessary or expedient to make
the Plan fully effective; and

            (vi)  make such other determinations as it may be authorized to make
in the Plan and as it may deem necessary and desirable for the purposes of the
Plan.

<PAGE>   4
Notwithstanding the foregoing, however, (1) no Option shall be granted after the
expiration of ten years from the effective date of the Plan specified in section
9 below, (2) the aggregate fair market value (determined as of the date the
Option is granted) of the Stock subject to Options that become exercisable for
the first time by any Employee during any calendar year under all Incentive
Stock Options of the Company and its Subsidiaries shall not exceed $100,000, and
(3) no person who is not an Employee of the Company or a Subsidiary shall be
entitled to receive Incentive Stock Options under the Plan.

      (b)   The Board may delegate administration of the Plan to a Committee of
the Board. The Committee shall consist of not less than three members appointed
by the Board. Subject to the foregoing, the Board may from time to time increase
the size of the Committee and appoint additional members, remove members (with
or without cause) and appoint new members in substitution therefor, or fill
vacancies, however caused. If the Board delegates administration of the Plan to
a Committee, the Committee shall have the powers theretofore possessed by the
Board with respect to the administration of the Plan (and references in this
Plan to the Board shall apply to the Committee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted
from time to time by the Board. The Board may abolish the Committee at any time
and revest in the Board the administration of the Plan.

      (c)   Notwithstanding anything in this section 4 to the contrary,
beginning at such time as the Company first registers a class of equity
securities under section 12 of the Exchange Act, all decisions to grant Options
shall be made by the Board or by a Committee comprised solely of two or more
Directors, each of whom is both a Non-Employee Director and an Outside Director,
or shall be made in another manner that satisfies the requirements of Section
16b-3, so that transactions between the Company and any Officer or Director
relating to such Options may be exempt from section 16(b) of the Exchange Act.

5.    TERMS AND CONDITIONS OF OPTIONS.

      Each Option granted shall be evidenced by an Option Agreement in
substantially the form attached hereto as Annex A or Annex B or such other form
as may be approved by the Board. Each Option Agreement shall include the
following terms and conditions and such other terms and conditions as the Board
may deem appropriate:

      (a)   OPTION TERM. Each Option Agreement shall specify the term for which
the Option thereunder is granted and shall provide that such Option shall expire
at the end of such term. The Board may extend such term; provided that, in the
case of an Incentive Stock Option, such extension shall not in any way
disqualify the Option as an Incentive Stock Option. The term of any Option,
including any such extensions, shall not exceed ten years from the date of
grant; provided that, in the case of an Incentive Stock Option granted to a Ten
Percent Shareholder, such term, including extensions, shall not exceed five
years from the date of grant.


                                       4
<PAGE>   5
      (b)   EXERCISE PRICE. Each Option Agreement shall specify the exercise
price per share, as determined by the Board at the time the Option is granted;
provided that the exercise price of an Incentive Stock Option shall be not less
than the fair market value, or if granted to a Ten Percent Shareholder, 110
percent of the fair market value, of one share of Stock on the date the Option
is granted, as such fair market value is determined by the Board.

      (c)   VESTING. Each Option Agreement shall specify when it is exercisable.
The total number of shares of Stock subject to an Option may, but need not, be
allotted in periodic installments (which may, but need not be, equal). An Option
Agreement may provide that from time to time during each of such installment
periods, the Option may become exercisable ("vest") with respect to some or all
of the shares allotted to that period, and may be exercised with respect to some
or all of the shares allotted to such period or any prior period as to which the
Option shall have become vested but shall not have been fully exercised. An
Option may be subject to such other terms and conditions on the time or times
when it may be exercised (which may be based on performance or other criteria)
as the Board deems appropriate.

      (d)   PAYMENT OF PURCHASE PRICE ON EXERCISE. Each Option Agreement shall
provide that the purchase price of the shares as to which such Option may be
exercised shall be paid to the Company at the time of exercise either (i) in
cash, or (ii) in the absolute discretion of the Board (which discretion may be
exercised in a particular case without regard to any other case or cases), at
the time of the grant or thereafter, (A) by the withholding of shares of Stock
issuable on exercise of the Option or the delivery to the Company of other Stock
owned by the Optionee, provided in either case that the Optionee has owned
shares of Stock equal in number to the shares so withheld for a period
sufficient to avoid a charge to the Company's reported earnings, (B) according
to a deferred payment or other arrangement (which may include, without limiting
the generality of the foregoing, the use of Stock) with the person to whom the
Option is granted or to whom the Option is transferred pursuant to section 5(e),
or (C) in any other form of legal consideration that may be acceptable to the
Board.

      In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate necessary to avoid
the treatment as interest, under any applicable provisions of the Code, of any
amounts other than amounts stated to be interest under the deferred payment
arrangement, or if less, the maximum rate permitted by law.

      (e)   NONTRANSFERABILITY. An Option shall not be sold, assigned,
transferred, pledged, hypothecated or otherwise disposed of by the Optionee
during his or her lifetime, whether by operation of law or otherwise, other than
by will or the laws of descent and distribution applicable to the Optionee, and
shall not be made subject to execution, attachment or similar process; provided
that the Board may in its discretion at the time of approval of the grant of an
Option or thereafter permit an Optionee to transfer an Option to a trust or
other entity established by the Optionee for estate planning purposes, and may
permit further transferability or impose conditions or limitations on any
permitted transferability. Otherwise, during the lifetime of an Optionee, an
Option shall be exercisable only by such Optionee.


                                       5
<PAGE>   6
      (f)   CONDITIONS ON EXERCISE OF OPTIONS AND ISSUANCE OF SHARES.

            (i)   SECURITIES LAW COMPLIANCE. The Plan, the grant and exercise of
Options thereunder and the obligation of the Company to sell and deliver shares
on exercise of Options shall be subject to all applicable Federal and state
laws, rules and regulations and to such approvals by any government or
regulatory agency as may be required, in the opinion of the Board. Shares shall
not be issued on exercise of an Option until (1) the listing of such shares on
any stock exchange on which the Stock may then be listed and compliance with all
requirements of such exchange, and (2) the completion of any registration or
qualification of such shares under any Federal or state law, including without
limitation the Securities Act and the Exchange Act, or any rule or regulation of
any government body which the Company determines in its sole discretion to be
necessary or advisable.

            (ii)  INVESTMENT REPRESENTATION. The Company may require any
Optionee, or any person to whom an Option is transferred, as a condition of
exercising such Option, to (1) give written assurances satisfactory to the
Company as to the Optionee's knowledge and experience in financial and business
matters or to employ a purchaser representative reasonably satisfactory to the
Company who is knowledgeable and experienced in financial and business matters,
and that he or she is capable of evaluating, alone or together with the
purchaser representative, the merits and risks of exercising the Option; and (2)
to give written assurances satisfactory to the Company stating that such person
is acquiring the Stock subject to the Option for such person's own account and
not with any present intention of selling or otherwise distributing the Stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall not apply if (A) the issuance of the Stock on the exercise
of the Option has been registered under a then currently effective registration
statement under the Securities Act, or (B) counsel for the Company determines as
to any particular requirement that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, with
the advice of its counsel, place such legends on stock certificates issued under
the Plan as the Company deems necessary or appropriate to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the Stock.

      (g)   EXERCISE AFTER DEATH OF OPTIONEE. If an Optionee dies (i) while an
Employee, Consultant or Director, or (ii) within three months after termination
of the Optionee's Continuous Status as an Employee, Consultant or Director
because of his or her Disability or retirement, his or her Options may be
exercised (to the extent that the Optionee was entitled to do so on the date of
death or termination) by the Optionee's estate or by a person who shall have
acquired the right to exercise the Options by bequest or inheritance, but only
within the period ending on the earlier of (1) one year after the Optionee's
death (or such shorter or longer period specified in the Option Agreement, which
period shall not be less than six months), or (2) the expiration date specified
in the Option Agreement. If after the Optionee's death, the Optionee's estate or
the person who acquired the right to exercise the Optionee's Options does not
exercise 


                                       6
<PAGE>   7
the Options within the time specified herein, the Options shall terminate and
the shares covered by such Options shall revert to and again become available
for issuance under the Plan.

      (h)   EXERCISE AFTER TERMINATION OF OPTIONEE'S CONTINUOUS STATUS AS AN
EMPLOYEE, CONSULTANT OR DIRECTOR AS A RESULT OF DISABILITY OR RETIREMENT. If an
Optionee's Continuous Status as an Employee, Consultant or Director terminates
as a result of the Optionee's Disability or retirement, and the Optionee does
not die within the following three months, the Optionee may exercise his or her
Options (to the extent that the Optionee was entitled to exercise them on the
date of termination), but only within the period ending on the earlier of (i)
six months after such termination (or such longer period specified in the Option
Agreement), or (ii) the expiration of the term set forth in the Option
Agreement. If after termination, the Optionee does not exercise his or her
Options within the time specified herein, the Options shall terminate, and the
shares covered by such Options shall revert to and again become available for
issuance under the Plan.

      (i)   NO EXERCISE AFTER TERMINATION OF OPTIONEE'S CONTINUOUS STATUS AS AN
EMPLOYMENT, CONSULTANT OR DIRECTOR OTHER THAN AS A RESULT OF DEATH, DISABILITY
OR RETIREMENT. If an Optionee's Continuous Status as an Employee, Consultant or
Director terminates other than as a result of the Optionee's death, Disability
or retirement, all right of the Optionee to exercise his or her Options shall
terminate on the date of termination of such Continuous Status as an Employee,
Consultant or Director. The Options shall terminate on such termination date,
and the shares covered by such Options shall revert to and again become
available for issuance under the Plan.

      (j)   EXCEPTIONS. Notwithstanding subsections (h), (i) and (j), the Board
shall have the authority to extend the expiration date of any outstanding Option
in circumstances in which it deems such action to be appropriate, provided that
no such extension shall extend the term of an Option beyond the expiration date
of the term of such Option as set forth in the Option Agreement.

      (k)   INCENTIVE STOCK OPTIONS. Each Option Agreement that provides for the
grant of an Incentive Stock Option shall contain such terms and conditions as
the Board determines to be necessary or desirable to qualify such Option as an
Incentive Stock Option within the meaning of section 422 of the Code.

      (l)   COMPANY'S REPURCHASE RIGHT. Each Option Agreement may, but is not
required to, include provisions whereby the Company shall have the right to
repurchase any and all shares acquired by an Optionee on exercise of any Option
granted under the Plan, at such price and on such other terms and conditions as
the Board may approve and as may be set forth in the Option Agreement. Such
right shall be exercisable by the Company after termination of an Optionee's
Continuous Status as an Employee, Consultant or Director, whenever such
termination may occur and whether such termination is voluntary or involuntary,
with cause or without cause, without regard to the reason therefor, if any.

6.    ADJUSTMENTS ON CHANGES IN STOCK.

      (a)   If any change in the Stock subject to the Plan or subject to any
Option occurs (through stock dividend, dividend in property other than cash,
recapitalization, reorganization, reclassification, stock split or reverse stock
split, liquidating dividend, combination or exchange of shares, merger or
consolidation, any direct or indirect offering of Stock at a price substantially
below fair market value, or any similar change affecting the Stock), the Board
will appropriately adjust the class(es) and maximum number of shares subject to
the Plan and the class(es) and number of shares and price per share of Stock
subject to the outstanding Options.

      (b)   In the event of (i) a merger or consolidation in which the Company
is not the surviving corporation, or (ii) a reverse merger in which the Company
is the surviving corporation but the shares of the Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise, then to the extent
permitted by applicable law: (1) any surviving corporation shall assume any
Options outstanding under the Plan or shall substitute similar options for those
outstanding under the Plan, or (2) any Options outstanding under the Plan shall
continue in full force and effect. If any surviving corporation refuses to
assume or continue such Options, or to substitute similar options for those
outstanding under the Plan, then such Options shall be terminated if not
exercised prior to the merger or reverse merger. If the Company dissolves or is
liquidated, any Options outstanding under the Plan shall terminate if not
exercise prior to such event.

7.    AMENDMENT OF THE PLAN.

      (a)   The Board may from time to time amend or modify the Plan for any
reason; provided that the Company will seek shareholder approval for any change
if and to the extent required by applicable law, regulation or rule.

      (b)   It is expressly contemplated that the Board may amend the Plan in
any respect the Board deems necessary or advisable to provide Optionees with the
maximum benefits provided or to be provided under the Code and the regulations
promulgated thereunder relating to Incentive Stock Options or to cause the Plan
or Incentive Stock Options to comply therewith.

      (c)   Rights and obligations under any Option granted before amendment of
the Plan shall not be altered or impaired by any amendment, unless the Optionee
consents in writing.

8.    TERMINATION OR SUSPENSION OF THE PLAN.

      The Board may suspend or terminate the Plan at any time for any reason.
Unless sooner terminated, the Plan shall terminate on the day prior to the tenth
anniversary of the earlier of the date the Plan is adopted by the Board or the
date the Plan is approved by the Company's 


                                       8

shareholders. No Options may be granted under the Plan while the Plan is
suspended or after it is terminated. Rights and obligations under any Option
granted while the Plan is in effect shall not be altered or impaired by
suspension or termination of the Plan, except with the written consent of the
Optionee.

9.    EFFECTIVE DATE OF THE PLAN.

      The effective date of the Plan shall be determined by the Board, subject
to approval by the shareholders of the Company holding not less than a majority
of the shares present and voting at an annual or special meeting or by written
consent. Notwithstanding the foregoing, if the Plan is approved by the Board
prior to such meeting or the giving of such consent, Options may be granted by
the Board as provided herein subject to such subsequent shareholder approval.

10.   WITHHOLDING TAXES.

      Whenever the Company proposes or is required to issue or transfer shares
of Stock under the Plan, the Company shall have the right to require the grantee
to remit to the Company an amount sufficient to satisfy any Federal, state or
local withholding tax requirements prior to the delivery of any certificate or
certificates for such shares. Alternatively, the Company may issue or transfer
such shares net of the number of shares sufficient to satisfy the withholding
tax requirements. For withholding tax purposes, the shares of Stock shall be
valued on the date the withholding obligation is incurred.

11.   MISCELLANEOUS.

      (a)   NO RIGHTS AS SHAREHOLDER. No Optionee, as such, shall have any
rights as a shareholder of the Company.

      (b)   NO RIGHTS TO CONTINUED EMPLOYMENT OR ENGAGEMENT. The Plan and any
Options granted under the Plan shall not confer on any Optionee any right with
respect to continuation of employment by the Company or any Subsidiary or
engagement as a Consultant or Director, nor shall they interfere in any way with
the right of the Company or any Subsidiary that employs or engages an Optionee
to terminate the Optionee's employment or engagement at any time.

      (c)   COMPLIANCE WITH SECTION 16 OF THE EXCHANGE ACT. Beginning at such
time as the Company first registers a class of equity securities under section
12 of the Exchange Act, the Company intends that the Plan shall comply in all
respects with Rule 16b-3. If after such time any provision of this Plan is found
not to be in compliance with Rule 16b-3, that provision shall be deemed to have
been amended or deleted as and to the extent necessary to comply with Rule
16b-3, and the remaining provisions of the Plan shall continue in full force and
effect without change. All transactions under the Plan after such time shall be
executed in accordance with the requirements of section 16 of the Exchange Act
and the applicable regulations promulgated thereunder.

                                THE SECURITIES TO WHICH THIS AGREEMENT RELATES
                                HAVE NOT BEEN REGISTERED UNDER THE SECURITIES

                                BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
                                OFFERED FOR SALE OR SOLD IN THE ABSENCE OF AN
                                EFFECTIVE REGISTRATION STATEMENT THEREFOR UNDER
                                SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY
                                TO THE CORPORATION THAT SUCH REGISTRATION IS NOT
                                REQUIRED.


                        INCENTIVE STOCK OPTION AGREEMENT


__________________, Optionee:

        Waste Connections., Inc. (the "Company"), pursuant to its 1997 Stock
Option Plan (the "Plan"), has this ______________, 19___, granted to you, the
optionee named above, an option to purchase shares of the common stock of the
Company ("Stock"). This option is intended to qualify as an "incentive stock
option" within the meaning of section 422 of the Internal Revenue Code of 1986,
as amended (the "Code").

        The grant under this Incentive Stock Option Agreement (the "Agreement")
is in connection with and in furtherance of the Company's compensatory benefit
plan for participation of the Company's Employees (including Officers),
Directors or Consultants and is intended to comply with Rule 701 promulgated by
the Securities and Exchange Commission under the Securities Act of 1933, as
amended (the "Act"). Capitalized terms used and not otherwise defined herein
shall have the meanings ascribed to them in the Plan. The option granted
hereunder shall be subject to and governed by the following terms and
conditions:

        1. The total number of shares of Stock subject to this option is
______________ shares. Subject to the limitations herein and in the Plan, this
option shall become exercisable (vest) as follows:


        Number of Shares                    Date of Earliest Exercise
        (Installment)                              (Vesting)


                                       1.
<PAGE>   2

The installments provided for are cumulative. Each such installment that becomes
exercisable shall remain exercisable until expiration or earlier termination of
the option.

        2.     (a)  The exercise price of this option is $_____________________
per share, being not less than 100 percent of [110 percent if Optionee is a Ten
Percent Shareholder] the fair market value of the Stock on the date of grant of
this option.

               (b)  Payment of the exercise price per share is due in full in
cash (including check) on exercise of all or any part of each installment that
has become exercisable by you; provided that, if at the time of exercise the
Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment of the exercise price, to the extent permitted by the Company and
applicable statutes and regulations, may be made by having the Company withhold
shares of Stock issuable on such exercise, by delivering shares of Stock already
owned by you, or by delivering a combination of cash and such shares. Such Stock
(i) shall be valued at its fair market value at the close of business on the
date of exercise, (ii) if originally acquired from the Company, must have been
held for the period required to avoid a charge to the Company's reported
earnings, and (iii) must be owned free and clear of any liens, claims,
encumbrances or security interests.

               (c)  Notwithstanding the foregoing, this option may be exercised
pursuant to a program developed under Regulation T as promulgated by the Federal
Reserve Board which results in the receipt of cash (or check) by the Company
prior to the issuance of Stock.

        3.     (a)  Subject to the provisions of this Agreement, you may elect 
at any time during your Continuous Status as an Employee, Consultant or Director
to exercise this option as to any part or all of the shares subject to this
option at any time during the term hereof, including, without limitation, a time
prior to the date of earliest exercise (vesting) stated in paragraph 1 hereof;
provided that:

                    (i) a partial exercise of this option shall be deemed to
cover first vested shares and then unvested shares next vesting;

                    (ii) any shares so purchased that shall not have vested as
of the date of exercise shall be subject to the purchase option in favor of the
Company as described in the Early Exercise Stock Purchase Agreement available
from the Company;

                    (iii) you shall enter into an Early Exercise Stock
Purchase Agreement in the form available from the Company with a vesting
schedule that will result in the same vesting as if no early exercise had
occurred; and

                    (iv) you acknowledge that the aggregate fair market value
(determined as of the date options are granted) of any Stock subject to
Incentive Stock Options granted to you by the Company or any parent or
Subsidiary that become exercisable for the first time during any 



                                       2.
<PAGE>   3

calendar year may not exceed $100,000, and agree that to the extent that the
aggregate fair market value of Stock with respect to which such Incentive Stock
Options are exercisable by you for the first time in a calendar year exceeds
$100,000, the options or portions thereof in excess of such limit shall be
treated (according to the order in which they were granted) as Nonqualified
Stock Options.

               (b) The election provided in this paragraph 3 to purchase shares
on the exercise of this option prior to the vesting dates shall cease on
termination of your Continuous Status as an Employee, Consultant or Director and
may not be exercised from or after the date thereof.

       4. This option may not be exercised for any number of shares that would
require the issuance of anything other than whole shares.

       5. Notwithstanding anything to the contrary herein, this option may not
be exercised unless the shares issuable on exercise of this option are then
registered under the Act or, if such shares are not then so registered, the
Company shall have determined that such exercise and issuance would be exempt
from the registration requirements of the Act.

       6. The term of this option commences on the date hereof and, unless
sooner terminated as set forth below or in the Plan, terminates on
___________________ (which date shall be no more than [ten years] [five years if
Optionee is a Ten Percent Shareholder] from the date this option is granted). In
no event may this option be exercised on or after the date on which it
terminates. This option shall terminate prior to the expiration of its term on
the day after the termination of your Continuous Status as an Employee,
Consultant or Director for any reason or for no reason, unless:

               (a) such termination is due to your retirement or Disability and
you do not die within the three months after such termination, in which event
the option shall terminate on the earlier of the termination date set forth
above or six months after such termination of your Continuous Status as an
Employee, Consultant or Director; or

               (b) such termination is due to your death, or such termination is
due to your retirement or Disability and you die within three months after such
termination, in which event the option shall terminate on the earlier of the
termination date set forth above or the first anniversary of your death.

               Notwithstanding any of the foregoing provisions to the contrary
however, this option may be exercised following termination of your Continuous
Status as an Employee, Consultant or Director only as to that number of shares
as to which it shall have been exercisable under paragraph 1 of this Agreement
on the date of such termination.



                                       3.
<PAGE>   4

        7.     (a)  This option may be exercised, to the extent specified above,
by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require pursuant
to subsection 5(f) of the Plan.

               (b)  By exercising this option you agree that:

                    (i) the Company may require you to enter into an arrangement

providing for the cash payment by you to the Company of any tax withholding
obligation of the Company arising by reason of (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture to which the shares are
subject at the time of exercise; or (3) the disposition of shares acquired on
such exercise;

                    (ii) you will notify the Company in writing within fifteen
days after the date of any disposition of any of the shares of the Stock issued
on exercise of this option that occurs within two years after the date of this
option grant or within one year after such shares of Stock are issued on
exercise of this option; and

                    (iii) the Company (or a representative of the underwriters)
may, in connection with an underwritten registration of the offering of any
securities of the Company under the Act, require that you not sell or otherwise
transfer or dispose of any shares of Stock or other securities of the Company
during such period (not to exceed 180 days) following the effective date (the
"Effective Date") of the registration statement of the Company filed under the
Act as may be requested by the Company or the representative of the
underwriters. For purposes of this restriction, you will be deemed to own
securities which (i) are owned directly or indirectly by you, including
securities held for your benefit by nominees, custodians, brokers or pledgees;
(ii) may be acquired by you within sixty days of the Effective Date; (iii) are
owned directly or indirectly, by or for your brothers or sisters (whether by
whole or half blood) spouse, ancestors and lineal descendants; or (iv) are
owned, directly or indirectly, by or for a corporation, partnership, estate or
trust of which you are a shareholder, partner or beneficiary, but only to the
extent of your proportionate interest therein as a shareholder, partner or
beneficiary thereof. You further agree that the Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such period.

          8.   You hereby represent and warrant to and agree with the Company as
follows:

               (a) You have been granted access to, and have reviewed carefully,
the Plan and such records of the Company as may be necessary to permit you to
evaluate the option and, before any exercise of the option, you will review such
records of the Company as may be necessary to permit you to evaluate the merits
and risks of an investment in Stock. You are entering into this Agreement and
the transactions contemplated hereby solely in reliance on your own
investigation and such review. You have had an opportunity to meet with the
officers of the 




                                       4.
<PAGE>   5

Company subsequent to review of such information to discuss with them your
questions concerning the Company and the terms and conditions of the
acquisitions hereunder.

               (b) You are acquiring the option and will acquire the Stock, if
at all, pursuant to this Agreement with your own funds, and not with the funds
of anyone else. You are acquiring the option and will acquire the Stock, if at
all, for your own account, not as a nominee or agent and not for the account of
any other person or firm. No one else has or will have on any exercise of the
option any interest, beneficial or otherwise, in the option or, on the exercise
of the option, in any of the shares of Stock to be acquired on such exercise.
You are not, and prior to any exercise of the option will not be, obligated to
transfer the option or any Stock or any interest therein to anyone else, and you
do not and will not have any agreement or understanding to do so. You are
acquiring the option and will purchase Stock on the exercise hereof, if at all,
for investment for an indefinite period and not with a view to the sale or
distribution of the option or any Stock or any part or all thereof, by public or
private sale or other disposition, and you have no intention of selling,
granting any participation in or otherwise distributing or disposing of any or
all of the option or any Stock or any interest therein. You do not, and on any
exercise of the option will not, intend to subdivide the option or any shares
purchased on exercise thereof with anyone.

               (c) At the time of any acquisition of Stock you will be able to
bear the economic risk of the investment in any Stock purchased. You are aware
that if you exercise the option, you must be prepared to hold any Stock received
for an indefinite period. You understand that neither the option nor the Stock
has been registered under the Act, on the ground, among others, that no
distribution or public offering of the Company's securities is to be effected
and any Stock acquired on exercise thereof will be acquired in connection with
transactions not involving any public offering within the meaning of section
4(2) of the Act. The Stock, if and when issued, will be "restricted securities",
as that term is defined in Rule 144 under the Act, and, accordingly, apart from
exercise of the option, the option and such Stock must be held indefinitely
unless they are subsequently registered under the Act or an exemption from such
registration is available. You understand and agree that the Company is not
under any obligation to register the option or any Stock under the Act or to
comply with any exemption under the Act.

               You understand that the Company is relying in part on your
representations as set forth herein for purposes of claiming the exemption from
registration under the Act provided in section 3(b) or 4(2) thereof and that the
basis for such exemption may not be present if, notwithstanding your
representations herein, you have in mind merely acquiring the option or shares
for resale on the occurrence or nonoccurrence of some predetermined event. You
do not have in mind merely acquiring the option or any shares for resale on the
occurrence or nonoccurrence of any predetermined event.

               (d) You have such knowledge and experience in financial and
business matters that the you are capable of evaluating the merits and risks of
the prospective investment contemplated by this Agreement, and you have
carefully reviewed and will carefully review all 


                                       5.
<PAGE>   6

the information regarding the Company, access to which has been and will be
accorded to you hereunder, are thoroughly familiar with the business, operations
and properties of the Company by virtue of such review and of your relationship
with the Company and have discussed with the officers of the Company any
questions you have with respect to the Company.

               (e) Without in any way limiting your representations as set forth
herein, you further agree that you shall in no event make any disposition of all
or any part of or interest in the Stock or the option and that the Stock and the
option shall not be encumbered, pledged, hypothecated, sold, assigned or
transferred by you nor shall you receive any consideration for the option or any
Stock or for any interest therein from any person, unless and until prior to any
proposed encumbrance, pledge, hypothecation, sale, assignment, transfer or other
disposition of the option or any Stock, either (i) a registration statement on
Form S-1 (or any other form replacing such form or appropriate for the purpose
under the Act) with respect to the option or the Stock, as the case may be,
proposed to be transferred or otherwise disposed of shall be then effective or
(ii)(1) you have notified the Company of the proposed disposition and have
furnished the Company with a detailed statement of the circumstances surrounding
the proposed disposition, (2) you have furnished the Company with an opinion of
counsel (obtained at your expense) in form and substance satisfactory to the
Company to the effect that such disposition will not require registration of the
option or any Stock, as the case may be, under the Act or qualification of the
option or any Stock, as the case may be, under any other securities law and (3)
counsel for the Company shall have concurred in such opinion and the Company
shall have advised you of such concurrence.

               (f)  If the Company proposes to sell Stock in a public offering
registered under the Act or exempt from registration under the Act, the
administrators of the securities laws of certain states may require as a
condition of registration or such exemption that some or all of the Shares be
deposited in an escrow or be subject to waivers of rights to dividends and
assets on liquidation, or both, for an extended period of time, subject to
release if specified financial or market requirements are met and partial
cancellation if such requirements are not met. You agree that you will enter
into any such escrow or waiver agreement that the Company may consider necessary
for the successful completion of such public offering.

               (g)  If, in the opinion of counsel for the Company, you at any
time act in any manner not consistent with your representations, warranties and
agreements in this Agreement, the Company may refuse to transfer the option or
any Stock until such time as counsel for the Company is of the opinion that such
transfer may be effected in compliance with all provisions of this Agreement and
such transfer will not require registration of the option or any Stock under the
Act or qualification of the option or any Stock under any other securities law.

               (h) You hereby agree to indemnify and defend the Company and its
directors, officers, employees and agents and hold them harmless from and
against any and all claims, liabilities, damages or expenses incurred on account
of or arising out of (i) any inaccuracy in or breach of any of your 
representations, warranties or agreements in this Agreement, including, 



                                       6.
<PAGE>   7

without limitation, the defense of any claim based on any allegation of fact
inconsistent with any of such representations, warranties or agreements; (ii)
the disposition of the option or any Stock that you may receive, contrary to any
of such representations, warranties and agreements; or (iii) any action, suit or
proceeding based on a claim that any of such representations, warranties or
agreements were inaccurate or misleading or otherwise cause for obtaining
damages or redress from the Company under the Act or any other securities law.

               (i) Certificates representing any Stock received on exercise of
the option will bear a legend on the face thereof (or on the reverse thereof
with a reference to such legend on the face thereof) substantially in the form
set forth below, which legend restricts the sale, transfer or disposition of the
Stock otherwise than in accordance with this Agreement:

     THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
     ENCUMBERED, PLEDGED, HYPOTHECATED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED
     OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR
     AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION AND CONCURRED IN BY
     THE CORPORATION'S COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED UNDER SAID
     ACT OR SUCH TRANSACTION COMPLIES WITH RULES PROMULGATED BY THE SECURITIES
     AND EXCHANGE COMMISSION UNDER SAID ACT. IN ADDITION, SALE, TRANSFER,
     ENCUMBRANCE, HYPOTHECATION, GIFT OR OTHER DISPOSITION OR ALIENATION OF SUCH
     SHARES OR ANY INTEREST THEREIN IS RESTRICTED BY AND SUBJECT TO AN INCENTIVE
     STOCK OPTION AGREEMENT DATED ________________, 19__, A COPY OF WHICH MAY BE
     INSPECTED AT THE PRINCIPAL OFFICE OF THE CORPORATION AND ALL OF THE
     PROVISIONS OF WHICH ARE INCORPORATED BY REFERENCE IN THIS CERTIFICATE.

               (j) If Stock acquired on exercise of this option is transferred
other than by will or by the laws of descent and distribution within two years
after the date this option is granted or within one year after the issuance of
such Stock on exercise of this option, such transfer shall be a "disqualifying
disposition" under the Code, and you must bear the tax consequences thereof.

               (k) The Company may require you to furnish to the Company, prior
and as a condition to the issuance of any Stock on any exercise of the option,
an agreement (in such form as the Company may specify) in which you confirm the
foregoing representations, warranties and agreements or make similar or
additional representations, warranties and agreements with respect to such
Stock.



                                       7.

        9.   This option is generally not transferable, except by will or by the
laws of descent and distribution, unless the Company expressly permits a
transfer, such as to a trust or other entity for estate planning purposes.
Unless the Company approves such a transfer, this option is exercisable during
your life only by you.

       10.     This Agreement is not an employment contract and nothing in this
Agreement shall be deemed to create in any way whatsoever any obligation on your

                                                            ________ shares of
                                                         Common Stock (Subject
                                                                to Adjustment)


                       WARRANT TO PURCHASE COMMON STOCK
                                      of
                           WASTE CONNECTIONS, INC.

                         Void after December 14, 2008


            This certifies that for value received,____, ("Holder") is entitled,
subject to the terms set forth below, at any time or from time to time before
5:00 p.m., Pacific standard time, on December 14, 2008, to purchase from Waste
Connections, Inc., a Delaware corporation (the "Company"), up to ____ fully paid
and nonassessable shares of the common stock, par value $0.01 per share, of the
Company (the "Common Stock") as constituted on December 15, 1998 (the "Issue
Date"), upon surrender hereof at the principal office of the Company, with the
subscription form attached hereto properly completed and duly executed, and
simultaneous payment therefor in lawful money of the United States at the price
of $2.80 per share, subject to adjustment as provided in Section 4 hereof (the
"Purchase Price"). The number and character of such shares of Common Stock are
also subject to adjustment as provided below. Such number shall be reduced at
such time or times as this Warrant is exercised in part by the number of shares
as to which this Warrant is then exercised. The term "Warrant Stock" shall mean,
unless the context otherwise requires, the stock and other securities and
property at any time receivable upon the exercise of this Warrant. The term
"warrant" as used herein shall include this Warrant and any warrants delivered
in substitution or exchange therefor as provided herein.

      1.    Method of Exercise; Payment. Subject to compliance with the
provisions of Section 7 hereof:


<PAGE>   2
            A.    Cash Exercise. This Warrant may be exercised as a whole, or in
part from time to time, by the Holder by delivering this Warrant, for
cancellation if it is exercised as a whole or for endorsement if it is exercised
in part, together with a Subscription in the form appearing at the end hereof
properly completed and duly executed by or on behalf of the Holder, to the
Company at its office in Roseville, California (or at the office of the agency
maintained for such purpose), accompanied by payment in cash or by certified or
official bank check payable to the order of the Company, in an aggregate amount
equal to the Purchase Price as then adjusted times the number of shares of
Warrant Stock as to which this Warrant is then being exercised. In the event of
any such exercise that is partial, the Company shall endorse this Warrant as
having been exercised to that extent and return this Warrant to the Holder. This
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Warrant Stock issuable upon such
exercise shall be treated for all purposes as the holder of such shares of
record as of the close of business on such date.

            B.    Net Issue Exercise. In lieu of exercising this Warrant
pursuant to Section 1.A, Holder may elect to receive shares equal to the value
of this Warrant (or the portion thereof being cancelled) by surrender of this
Warrant at such office together with notice of such election, in which event the
Company shall issue to Holder a number of shares of Warrant Stock computed using
the following formula:

                                 X = Y (A-B)
                                     -------
                                        A

Where X = the number of shares of Warrant Stock to be issued to Holder.

      Y =   the number of shares of Warrant Stock purchasable under this
            Warrant at the date of such calculation or, if only a portion of
            this Warrant is being exercised, the portion of this Warrant being
            cancelled at the date of such calculation.

      A =   the fair market value of one share of Warrant Stock purchasable
            under this Warrant at the date of such calculation.

      B =   Purchase Price (as adjusted to the date of such calculations).

For purposes of this Warrant, fair market value of one share of Warrant Stock
shall mean:

            (1)   The average of the closing bid and asked prices of the Common
Stock quoted on the NASDAQ Stock Market or the closing price quoted on any
national securities 


                                       2
<PAGE>   3
exchange on which the Common Stock is listed, whichever is applicable, as
published in the Western Edition of The Wall Street Journal for the ten trading
days prior to the date of determination of fair market value; or

            (2)   If the Common Stock is not traded on the NASDAQ stock market
or on such an exchange, an amount reasonably determined in good faith by the
Board of Directors to be the fair market value.

            C.    Delivery of Stock Certificates. The Company will, or will
direct its transfer agent to, issue, as soon as practicable after any exercise
of this Warrant under Section 1 and in any event within thirty days thereafter,
at its expense (including the payment by it of any applicable issue taxes), in
the name of and deliver to the Holder, or as the Holder may direct (on payment
by the Holder of any applicable transfer taxes) a certificate or certificates
for the number of fully paid and nonassessable shares of Warrant Stock as to
which this warrant is so exercised.

      2.    Payment of Taxes. All shares of Warrant Stock issued upon the
exercise of this Warrant shall be validly issued, fully paid and nonassessable,
and the Company shall pay all taxes and other governmental charges that may be
imposed in respect of the issuance or delivery thereof. The Company shall not be
required, however, to pay any tax or other charge imposed in connection with any
transfer involved in the issue of any certificate for shares of Warrant Stock in
any name other than that of the Holder and, in such case, the Company shall not
be required to issue or deliver any stock certificate until such tax or other
charge has been paid, or it has been established to the Company's satisfaction
that no tax or other charge is due.

      3.    A. Transfer. Subject to Section 7, this Warrant and all rights
hereunder are transferable, as a whole or in part, on the books of the Company
maintained for such purpose at the office specified pursuant to Section 1.A, by
the Holder in person, or by duly authorized attorney, upon surrender of this
Warrant properly endorsed and upon payment of any necessary transfer tax or
other governmental charge imposed upon such transfer.

            Upon any partial transfer, the Company will issue and deliver to the
Holder a new warrant or warrants of like tenor with respect to the shares of
Warrant Stock not so transferred. In lieu of any fraction of a share to which
the Holder would otherwise be entitled, the Company may deliver to the Holder
cash in an amount equal to such fraction of the current fair market value of one
full share determined in the manner provided in Section 1.B.

            Each taker and holder of this Warrant, by taking or holding the
same, consents and agrees that this Warrant, when endorsed in blank, shall be
deemed negotiable and that when this Warrant shall have been so endorsed, the
person in possession of this Warrant may be treated by the Company, and all
other persons dealing with this Warrant, as the absolute owner 


                                       3
<PAGE>   4
hereof for any purpose and as the person entitled to exercise the rights
represented hereby, any notice to the contrary notwithstanding, but until a
transfer of this Warrant on the books of the Company, the Company may treat the
Holder as the owner for all purposes.

            B.    Exchange. At the request of the Holder, the Company shall
exchange this Warrant for two or more Warrants of like tenor entitling the
Holder to purchase the same aggregate number of shares of Warrant Stock, each
new Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder shall designate at the time of such exchange; provided that
the Holder shall not be entitled so to exchange this Warrant or any warrant
received in any such exchange on more than an aggregate of five occasions.

      4.    A. Adjustment for Dividends in Other Stock or Property. In case at
any time, or from time to time, after the Issue Date the holders of the Common
Stock of the Company (or any shares of stock or other securities at the time
receivable upon the exercise of this Warrant), shall have received, or, on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive, without payment therefor:

            (1)   Other or additional stock or other securities or property
(other than cash) by way of a dividend;

            (2)   Any cash paid or payable out of capital, or capital surplus,
or surplus created as a result of a revaluation of property; or

            (3)   Other or additional stock or other securities or property
(including cash) by way of a stock-split, spin-off, reclassification,
combination of shares or similar corporate rearrangement;

then, and in each such case, the Holder, upon the exercise hereof (as provided
in Section 1), shall be entitled to receive the number of shares of Warrant
Stock and other securities and property (including cash in the cases referred to
in clauses (2) and (3) above) which the Holder would hold on the date of such
exercise if on the Issue Date the Holder had been the holder of record of the
number of shares of Common Stock called for on the face of this Warrant and had
thereafter, during the period from the Issue Date to and including the date of
such exercise, retained such shares and/or all other or additional stock and
other securities and property (including cash in the cases referred to in
clauses (2) and (3) above) receivable by the Holder as aforesaid during such
period, giving effect to all adjustments during such period pursuant to this
Section 4.

            B.    Merger, Sale of Assets, etc. If at any time while this
Warrant, or any portion thereof, is outstanding and unexpired there shall be (i)
a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), 


                                       4
<PAGE>   5
(ii) a merger or consolidation of the Company with or into another corporation
in which the Company is not the surviving entity, or a reverse triangular merger
in which the Company is the surviving entity but the shares of the Company's
capital stock outstanding immediately prior to the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash, or otherwise, or (iii) a sale or transfer of the Company's properties and
assets as, or substantially as, an entirety to any other person, then, as a part
of such reorganization, merger, consolidation, sale or transfer, lawful
provision shall be made so that the holder of this Warrant shall thereafter be
entitled to receive upon exercise of this Warrant, during the period specified
herein and upon payment of the Purchase Price then in effect, the number of
shares of stock or other securities or property of the successor corporation
resulting from such reorganization, merger, consolidation, sale or transfer that
a holder of the shares deliverable upon exercise of this Warrant would have been
entitled to receive in such reorganization, consolidation, merger, sale or
transfer if this Warrant had been exercised immediately before such
reorganization, merger, consolidation, sale or transfer, all subject to further
adjustment as provided in this Section 4. The foregoing provisions of this
Section 4.B shall similarly apply to successive reorganizations, consolidations,
mergers, sales and transfers and to the stock or securities of any other
corporation that are at the time receivable upon the exercise of this Warrant.
If the per-share consideration payable to the holder hereof for shares in
connection with any such transaction is in a form other than cash or marketable
securities, then the value of such consideration shall be determined in good
faith by the Company's Board of Directors. In all events, appropriate adjustment
(as determined in good faith by the Company's Board of Directors) shall be made
in the application of the provisions of this Warrant with respect to the rights
and interests of the Holder after the transaction, to the end that the
provisions of this Warrant shall be applicable after that event, as near as
reasonably may be, in relation to any shares or other property deliverable after
that event upon exercise of this Warrant.

            C.    Reclassification, etc. If the Company, at any time while this
Warrant, or any portion hereof, remains outstanding and unexpired by
reclassification of securities or otherwise, shall change the Warrant Stock into
the same or a different number of securities of any other class or classes, this
Warrant shall thereafter represent the right to acquire such number and kind of
securities as would have been issuable as the result of such change with respect
to the Warrant Stock immediately prior to such reclassification or other change
and the Purchase Price therefor shall be appropriately adjusted, all subject to
further adjustment as provided in this Section 4.

            D.    Split, Subdivision or Combination of Shares. If the Company at
any time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall split, subdivide or combine the Warrant Stock, into a different
number of securities of the same class, the Purchase Price for such securities
shall be proportionately decreased in the case of a split or subdivision or
proportionately increased in the case of a combination.


                                       5
<PAGE>   6
            E.    Adjustments for Dividends in Stock or Other Securities or
Property. If while this Warrant, or any portion hereof, remains outstanding and
unexpired the holders of the securities as to which purchase rights under this
Warrant exist at the time shall have received, or, on or after the record date
fixed for the determination of eligible stockholders, shall have become entitled
to receive, without payment therefor, other or additional stock or other
securities or property (other than cash) of the Company by way of dividend, then
and in each case, this Warrant shall represent the right to acquire, in addition
to the number of shares of Warrant Stock receivable upon exercise of this
Warrant, and without payment of any additional consideration therefor, the
amount of such other or additional stock or other securities or property (other
than cash) of the Company that such Holder would hold on the date of such
exercise had it been the holder of record of the Warrant Stock on the date
hereof and had thereafter, during the period from the date hereof to and
including the date of such exercise, retained such shares and/or all other
additional stock available by it as aforesaid during such period, giving effect
to all adjustments called for during such period by the provisions of this
Section 4.

            F.    Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment pursuant to this Section 4, the Company at its
expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to each Holder of this Warrant a certificate
setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The Company shall, upon the
written request, at any time, of any such Holder, furnish or cause to be
furnished to such Holder a like certificate setting forth: (i) such adjustments
and readjustments; (ii) the Purchase Price at the time in effect; and (iii) the
number of shares and the amount, if any, of other property that at the time
would be received upon the exercise of the Warrant.

            G.    No Dilution or Impairment. The Company will not by amendment
of its Articles of Incorporation, or through reorganization, consolidation,
merger, dissolution, issuance or sale of securities, sale of assets, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the Holder against
dilution or other impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of Warrant Stock
receivable upon the exercise of this Warrant above the amount payable therefor
upon such exercise, (b) will take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares upon the exercise of this Warrant, and (c) will take no
action to amend its Articles of Incorporation which would change to the
detriment of the holders of Common Stock (whether or not any Common Stock be at
the time outstanding) the dividend or voting rights of the Company's Common
Stock (as constituted on the Issue Date).

            H.    Notices of Record Date. In case:


                                       6
<PAGE>   7
            (1)   The Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time receivable upon the exercise of
this Warrant) for the purpose of entitling them to receive any dividend or other
distribution or any right to subscribe for or purchase any shares of stock of
any class or any other securities, or to receive any other right, or

            (2)   Of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any split or combination
of shares of any class of capital stock of the Company, any consolidation or
merger of the Company with or into another corporation, or any conveyance of all
or substantially all of the assets of the Company to another corporation, or

            (3)   Of any voluntary dissolution, liquidation or winding-up of the
Company, then, and in each such case, the Company will mail or cause to be
mailed to the Holder a notice specifying, as the case may be, (a) the date on
which a record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, or (b) the date on which such reorganization, reclassification, split,
combination, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or such stock or securities at the time
receivable upon the exercise of this Warrant) shall be entitled to exchange
their shares of Common Stock (or such other stock or securities) for securities
or other property deliverable upon such reorganization, reclassification, split,
combination, consolidation, merger, conveyance, dissolution, liquidation or
winding-up. Such notice shall be mailed at least 90 days prior to the date
therein specified.

      5.    Loss or Mutilation. Upon receipt by the Company of evidence
reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of this Warrant, and of indemnity reasonably
satisfactory to it, and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver in lieu
thereof a new warrant of like tenor.

      6.    Reservation of Common Stock. The Company shall at all times reserve
and keep available for issue upon the exercise of this Warrant such number of
its authorized but unissued shares of Warrant Stock as will be sufficient to
permit the exercise in full of this Warrant.

      7.    Investment Intent. The Holder, by accepting this Warrant, represents
and warrants to the Company as follows:

            A.    Acquisition for Own Account. The Holder is acquiring this
Warrant and will acquire the shares of Warrant Stock on exercise of this Warrant
with the Holder's own funds, for the Holder's own account, not as a nominee or
agent. The Holder is not obligated to 


                                       7
<PAGE>   8
transfer this Warrant or any Warrant Stock to anyone else nor has any agreements
or understandings to do so. The Holder is purchasing or will purchase this
Warrant and the Warrant Stock for investment for an indefinite period and not
with a view to any sale or distribution thereof, by public or private sale or
other disposition, and has no intention of selling, granting any participation
in or otherwise distributing or disposing of any thereof. The Holder does not
intend to subdivide the Holder's purchase with anyone.

            B.    Restricted Securities. The Holder is able to bear the economic
risk of the Holder's investment in this Warrant and the Warrant Stock and is
aware that the Holder must be prepared to hold this Warrant and the Warrant
Stock for an indefinite period and that this Warrant and the Warrant Stock have
not been registered under the Securities Act of 1933, as amended (the "Act"), on
the ground that no distribution or public offering of this Warrant or the
Warrant Stock is to be effected and this Warrant or the Warrant Stock are being
or will be issued by the Company without any public offering within the meaning
of Section 4(2) of the Act.

            C.    Sophistication. The Holder is an "accredited investor" as that
term is defined in Regulation D under the Act. The Holder has such knowledge and
experience in financial and business matters that the Holder is capable of
evaluating the merits and risks of the Holder's investment in this Warrant and
the Warrant Stock.

            D.    Agreement to Refrain from Resales. Without in any way limiting
the Holder's representations herein, the Holder further agrees that the Holder
shall not encumber, pledge, hypothecate, sell, assign, transfer or otherwise
dispose of this Warrant or any Warrant Stock, unless and until, prior to any
proposed encumbrance, pledge, hypothecation, sale, assignment, transfer or other
disposition, either (i) a registration statement on Form S-l (or any other form
appropriate for the purpose or replacing such form) under the Act with respect
thereto shall be then effective (ii)(a) the Holder shall have furnished the
Company with a statement of the circumstances of the proposed disposition and an
opinion of counsel (obtained at the Holder's expense) satisfactory to the
Company to the effect that such disposition will not require registration under
the Act and (b) counsel for the Company shall have concurred in such opinion of
counsel and the Company shall have advised the Holder of such concurrence; or
(iii) the Warrant Stock can then be sold pursuant to Rule 144 under the Act.

            E.    Certificates to be Legended. The Holder understands and agrees
that this Warrant, any warrant issued to replace this Warrant and any
certificate representing Warrant Stock will bear a legend on the face thereof
(or on the reverse thereof with a reference to such legend on the face thereof)
in substantially the form set forth on the first page of this Warrant and any
other legend that the Company considers necessary or appropriate to comply with
any applicable securities law.


                                       8
<PAGE>   9
            8.    Registration. The Company acknowledges that it has granted to
certain holders of its capital stock certain rights to registration of such
capital stock for resale under the Act, the terms and conditions of which rights
are set forth in an Investors' Rights Agreement dated as of September 30, 1997.
The Company covenants and agrees to seek an amendment to the Investors' Rights
Agreement to include the Warrant Stock in the Registrable Securities to which
the registration rights set forth in Section 1 of the Investors' Rights
Agreement so that the Holder shall be entitled to identical registration rights
pari passu with such holders of capital stock as if the Holder had acquired the
Warrant Stock concurrently with such holders and pursuant to the Investors'
Rights Agreement. If such amendment is not consented to by the holders of a
majority of the Registrable Securities as required by the Investors' Rights
Agreement, the Company shall promptly prepare and thereafter enter into with the
Holder a Registration Rights Agreement providing for the same registration
rights as the Investors' Rights Agreement, which rights shall be subject and
subordinate only to those set forth in the Investors' Rights Agreement.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.


                            WARRANT TO PURCHASE STOCK

Company:  WASTE CONNECTIONS, INC.
Number of Shares:  200,000
Class of Stock:  Common
Initial Exercise Price:  $0.01 per Share
Issue Date: September 30, 1997
Expiration Date: September 29, 2004


        THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, IMPERIAL BANK, or its designee ("Holder")
is entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth of this Warrant.

ARTICLE 1. EXERCISE.

        1.1 Method of Exercise. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

        1.2 Conversion Right. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share as of the date of conversion. The fair market value of
the Shares shall be determined pursuant Section 1.4.

        1.3 Omitted.

        1.4 Fair Market Value. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall negotiate in good faith for up to four days as
to the correct valuation. If they have not agreed upon such valuation after such
negotiation, Company and Holder shall promptly agree upon a reputable investment
banking firm to undertake such valuation. If the valuation of such investment
banking firm is greater than that determined by the Board of Directors, then all
fees and expenses of such investment banking firm shall be paid by the Company.
In all other circumstances, such fees and expenses shall be paid by Holder.

        1.5 Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.



                                       1
<PAGE>   2
        1.6 Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

        1.7 Repurchase on Sale, Merger, or Consolidation of the Company.

               1.7.1. "Acquisition". For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

               1.7.2. Assumption of Warrant. Upon the closing of any Acquisition
the successor entity shall assume the obligations of this Warrant, and this
Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

               1.7.3. Purchase Right. Notwithstanding the foregoing, at the
election of Holder, the Company shall purchase the unexercised portion of this
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

        2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive, without cost to Holder, the total number and kind of securities
to which Holder would have been entitled had Holder owned the Shares of record
as of the date the dividend or subdivision occurred.

        2.2 Reclassification, Exchange or Substitution. Upon any 
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

        2.3 Adjustments for Combinations, Etc. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased, and vice
versa.



                                       2
<PAGE>   3

               2.4 Adjustments for Diluting Issuances. The Warrant Price and the
number of Shares issuable upon exercise of this Warrant shall be subject to
adjustment from time to time in the manner set forth in Holder's Anti-Dilution
Agreement.

               2.5 No Impairment. The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment. If the Company
takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable upon
exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

               2.6 Fractional Shares. No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the fractional interest by the fair market value of a full Share.

               2.7 Certificate as to Adjustments. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

               3.1 Representations and Warranties. The Company hereby represents
and warrants to the Holder as follows: All Shares which may be issued upon the
exercise of the purchase right represented by this Warrant, and all securities,
if any, issuable upon conversion of the Shares, shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws; the number of Shares that
may be purchased under this Warrant is equal to four percent (4.0%) of the
issued and outstanding stock of the Company on the Issue Date of this Warrant;
and the Initial Purchase Price is equal to the purchase price at which the
Company last sold its shares of Common Stock to any person.

               3.2 Notice of Certain Events. If the Company proposes at any time
(a) to declare any dividend or distribution upon its common stock, whether in
cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (c) to effect any reclassification or recapitalization of common
stock; (d) to merge or consolidate with or into any other corporation, or sell,
lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters
referred to in (c) and (d) above; (2) in the case of the matters referred to in
(c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of common
stock will be entitled to exchange their common stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.



                                       3
<PAGE>   4

               3.3 Information Rights. So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
shareholders of the Company, (b) within ninety (90) days after the end of each
fiscal year of the Company, the annual audited financial statements of the
Company certified by independent public accountants of recognized standing and
(c) within forty-five (45) days after the end of each of the first three
quarters of each fiscal year, the Company's quarterly, unaudited financial
statements.

               3.4 Registration Under Securities Act of 1933, as amended. The
Company agrees that the Shares or, if the Shares are convertible into common
stock of the Company, such common stock, shall be subject to the registration
rights set forth on Exhibit A, if attached.

ARTICLE 4. MISCELLANEOUS.

               4.1 Term; Notice of Expiration. This Warrant is exercisable, in
whole or in part, at any time and from time to time on or before the Expiration
Date set forth above.

               4.2 Legends. This Warrant and the Shares (and the securities
issuable, directly or indirectly, upon conversion of the Shares, if any) shall
be imprinted with a legend in substantially the following form:

        THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
        AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED
        WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT TO
        RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
        CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

               4.3 Compliance with Securities Laws on Transfer. This Warrant and
the Shares issuable upon exercise this Warrant (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) may not be
transferred or assigned in whole or in part without compliance with applicable
federal and state securities laws by the transferor and the transferee
(including, without limitation, the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Company, as reasonably
requested by the Company). The Company shall not require Holder to provide an
opinion of counsel if the transfer is to an affiliate of Holder or if there is
no material question as to the availability of current information as referenced
in Rule 144(c), Holder represents that it has complied with Rule 144(d) and (e)
in reasonable detail, the selling broker represents that it has complied with
Rule 144(f), and the Company is provided with a copy of Holder's notice of
proposed sale.

               4.4 Transfer Procedure. Subject to the provisions of Section 4.2,
Holder may transfer all or part of this Warrant or the Shares issuable upon
exercise of this Warrant (or the securities issuable, directly or indirectly,
upon conversion of the Shares, if any) by giving the Company notice of the
portion of the Warrant being transferred setting forth the name, address and
taxpayer identification number of the transferee and surrendering this Warrant
to the Company for reissuance to the transferee(s) (and Holder if applicable).
Unless the Company is filing financial information with the SEC pursuant to the
Securities Exchange Act of 1934, the Company shall have the right to refuse to
transfer any portion of this Warrant to any person who directly competes with
the Company. If Holder proposes to transfer the Warrant before the Company has
sold the Shares under the Securities Act of 1933, as amended, Holder shall first
offer to transfer the Warrant to the Company on substantially the same terms and
for the same price. If the Company elects within five (5) days to accept such
offer, the Company shall promptly purchase the Warrant on such terms. If the
Company fails to accept such offer, then Holder may transfer the Warrant to the
proposed transferee in accordance with such terms.

               4.5 Notices. All notices and other communications from the
Company to the Holder, or vice versa, shall be deemed delivered and effective
when given personally or mailed by first-class registered or certified mail,
postage prepaid, at such address as may have been furnished to the Company or
the Holder, as the case may be, in writing by the Company or such holder from
time to time.

               4.6 Waiver. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.

               4.7 Attorneys Fees. In the event of any dispute between the
parties concerning the terms and provisions of this Warrant, the party
prevailing in such dispute shall be entitled to collect from the other party all
costs incurred in such dispute, including reasonable attorneys' fees.

               4.8 Governing Law. This Warrant shall be governed by and
construed in accordance with the laws of the State of California, without giving
effect to its principles regarding conflicts of law.

                             WASTE CONNECTIONS, INC.
                             ANTIDILUTION AGREEMENT


        THIS ANTIDILUTION AGREEMENT is entered into as of September 30, 1997, by
and between IMPERIAL BANK ("Purchaser") and WASTE CONNECTIONS, INC. (the
"Company").

                                    RECITALS

        A. Concurrently with the execution of this Antidilution Agreement, the
Purchaser is purchasing from the Company two Warrants to Purchase Stock (each, a
"Warrant') pursuant to which Purchaser has the right to acquire from the Company
the Shares (as defined in the Warrant).

        B. By this Antidilution Agreement, the Purchaser and the Company desire
to set forth the adjustment in the number of Shares issuable upon exercise of
the Warrant as a result of a diluting issuance.

        C. Capitalized terms used herein shall have the same meaning as set
forth in the Warrant.

           NOW, THEREFORE, in consideration of the mutual promises, covenants
and conditions hereinafter set forth, the parties hereto mutually agree as
follows:

           1. Definitions. As used in this Antidilution Agreement, the following
terms have the following respective meanings:

               (a) "Option" means any right, option, or warrant to subscribe
for, purchase, or otherwise acquire common stock or Convertible Securities.

               (b) "Convertible Securities" means any evidences of indebtedness,
shares of stock, or other securities directly or indirectly convertible into or
exchangeable for common stock.

               (c) "Issue" means to grant, issue, sell, assume, or fix a record
date for determining persons entitled to receive, any security (including
Options), whichever of the foregoing is the first to occur.

               (d) "Additional Common Shares" means any common stock (including
reissued shares) issued (or deemed to be issued pursuant to Section 2) after the
date of the Warrant. Additional Common Shares does not include, however, any
common stock issued in a transaction described in Sections 2.1 and 2.2 of the
Warrant; any common stock Issued upon conversion of preferred stock outstanding
on the date of the Warrant; the Shares; or common stock Issued as incentive or
in a nonfinancing transaction to employees, officers, directors, or consultants
to the Company; or the exercise of any Option.

               (e) The shares of common stock ultimately Issuable upon exercise
of an Option (including the shares of common stock ultimately Issuable upon
conversion or exercise of a Convertible Security Issuable pursuant to an Option)
are deemed to be Issued when the Option is Issued. The shares of common stock
ultimately Issuable upon conversion or exercise of a Convertible Security (other
than a Convertible Security Issued pursuant to an Option) shall be deemed Issued
upon Issuance of the Convertible Security.

        2. Deemed Issuance of Additional Common Shares. The shares of common
stock ultimately Issuable upon exercise of an Option (including the shares of
common stock ultimately Issuable upon conversion or exercise of a Convertible
Security Issuable pursuant to an Option) are



                                       1
<PAGE>   9

deemed to be Issued when the Option is Issued. The shares of common stock
ultimately Issuable upon conversion or exercise of a Convertible Security (other
than a Convertible Security Issued pursuant to an Option) shall be deemed Issued
upon Issuance of the Convertible Security. The maximum amount of common stock
Issuable is determined without regard to any future adjustments permitted under
the instrument creating the Options or Convertible Securities.

        3. Adjustment of Warrant Price for Diluting Issuances.

           3.1 Weighted Average Adjustment. If the Company Issues Additional
Common Shares after the date of the Warrant and the consideration per Additional
Common Share (determined pursuant to Section 9) is less than the Warrant Price
in effect immediately before such Issue, the Warrant Price in effect immediately
before such Issue shall be reduced, concurrently with such Issue, to a price
(calculated to the nearest hundredth of a cent) determined by multiplying the
Warrant Price by a fraction:

               (a) the numerator of which is the amount of common stock
outstanding immediately before such Issue plus the amount of common stock that
the aggregate consideration received by the Company for the Additional Common
Shares would purchase at the Warrant Price in effect immediately before such
Issue, and

               (b) the denominator of which is the amount of common stock
outstanding immediately before such Issue plus the number of such Additional
Common Shares.

           3.2 Adjustment of Number of Shares. Upon each adjustment of the
Warrant Price, the number of Shares issuable upon exercise of the Warrant shall
be increased to equal the quotient obtained by dividing (a) the product
resulting from multiplying (i) the number of Shares issuable upon exercise of
the Warrant and (ii) the Warrant Price, in each case as in effect immediately
before such adjustment, by (b) the adjusted Warrant Price.

           3.3 Securities Deemed Outstanding. For the purpose of this Section 3,
all securities issuable upon exercise of any outstanding Convertible Securities
or Options, warrants, or other rights to acquire securities of the Company shall
be deemed to be outstanding.

        4. No Adjustment for Issuances Following Deemed Issuances. No adjustment
to the Warrant Price shall be made upon the exercise of Options or conversion of
Convertible Securities.

        5. Adjustment Following Changes in Terms of Options or Convertible
Securities. If the consideration payable to, or the amount of common stock
Issuable by, the Company increases or decreases, respectively, pursuant to the
terms of any outstanding Options or Convertible Securities, the Warrant Price
shall be recomputed to reflect such increase or decrease. The recomputation
shall be made as of the time of the Issuance of the Options or Convertible
Securities. Any changes in the Warrant Price that occurred after such Issuance
because other Additional Common Shares were Issued or deemed Issued shall also
be recomputed.

        6. Recomputation Upon Expiration of Options or Convertible Securities.
The Warrant Price computed upon the original Issue of any Options or Convertible
Securities, and any subsequent adjustments based thereon, shall be recomputed
when any Options or rights of conversion under Convertible Securities expire
without having been exercised. In the case of Convertible Securities or Options
for common stock, the Warrant Price shall be recomputed as if the only
Additional Common Shares Issued were the shares of common stock actually Issued
upon the exercise of such securities, if any, and as if the only consideration
received therefor was the consideration actually received upon the Issue,
exercise or conversion of the Options or Convertible Securities. In the case of
Options for Convertible Securities, the Warrant Price shall be recomputed as if
the only Convertible Securities



                                       2
<PAGE>   10

Issued were the Convertible Securities actually Issued upon the exercise
thereof, if any, and as if the only consideration received therefor was the
consideration actually received by the Company (determined pursuant to Section
9), if any, upon the Issue of the Options for the Convertible Securities.

        7. Limit on Readjustments. No readjustment of the Warrant Price pursuant
to Sections 5 or 6 shall increase the Warrant Price more than the amount of any
decrease made in respect of the Issue of any Options or Convertible Securities.

        8. 30 Day Options. In the case of any Options that expire by their terms
not more than 30 days after the date of Issue thereof, no adjustment of the
Warrant Price shall be made until the expiration or exercise of all such
Options.

        9. Computation of Consideration. The consideration received by the
Company for the Issue of any Additional Common Shares shall be computed as
follows:

           (a) Cash shall be valued at the amount of cash received by the
Corporation, excluding amounts paid or payable for accrued interest or accrued
dividends.

           (b) Property. Property other than cash shall be computed at the fair
market value thereof at the time of the Issue as determined in good faith by the
Board of Directors of the Company.

           (c) Mixed Consideration. The consideration for Additional common
Shares Issued together with other property of the Company for consideration that
covers both shall be determined in good faith by the Board of Directors.

           (d) Options and Convertible Securities. The consideration per
Additional Common Share for Options and Convertible Securities shall be
determined by dividing:

               (i) the total amount, if any, received or receivable by the
Company for the Issue of the Options or Convertible Securities, plus the minimum
amount of additional consideration (as set forth in the instruments relating
thereto, without regard to any provision contained therein for a subsequent
adjustment of such consideration) payable to the Company upon exercise of the
Options or conversion of the Convertible Securities, by

               (ii) the maximum amount of common stock (as set forth in the
instruments relating thereto, without regard to any provision contained therein
for a subsequent adjustment of such number) ultimately Issuable upon the
exercise of such Options or the conversion of such Convertible Securities.

        10. General.

            10.1 Governing Law. This Antidilution Agreement shall be governed in
all respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

            10.2 Successors and Assigns. Except as otherwise expressly provided

        Warrant No. 5                                        Warrant to Purchase
                                                               140,000 shares of
                                                           Common Stock (Subject
                                                                  to Adjustment)


                        WARRANT TO PURCHASE COMMON STOCK
                                       of
                             WASTE CONNECTIONS, INC.

                           Void after January 29, 2008


               This certifies that for value received, FSC Corp. ("Holder"), is
entitled, subject to the terms set forth below, at any time or from time to time
before 5:00 p.m., Pacific standard time, on January 29, 2008, to purchase from
Waste Connections, Inc., a Delaware corporation (the "Company"), up to 140,000
fully paid and nonassessable shares of the common stock, par value $0.01 per
share, of the Company (the "Common Stock") as constituted on January 30, 1998
(the "Issue Date"), upon surrender hereof at the principal office of the
Company, with the subscription form attached hereto properly completed and duly
executed, and simultaneous payment therefor in lawful money of the United States
at the price of $2.80 per share, subject to adjustment as provided in Section 4
hereof (the "Purchase Price"). The number and character of such shares of Common
Stock are also subject to adjustment as provided below. Such number shall be
reduced at such time or times as this Warrant is exercised in part by the number
of shares as to which this Warrant is then exercised. The term "Warrant Stock"
shall mean, unless the context otherwise requires, the stock and other
securities and property at any time receivable upon the exercise of this
Warrant. The term "warrant" as used herein shall include this Warrant and any
warrants delivered in substitution or exchange therefor as provided herein.

        1. Method of Exercise; Payment. Subject to compliance with the
provisions of Section 7 hereof:


<PAGE>   2

               A. Cash Exercise. This Warrant may be exercised as a whole, or in
part from time to time, by the Holder by delivering this Warrant, for
cancellation if it is exercised as a whole or for endorsement if it is exercised
in part, together with a Subscription in the form appearing at the end hereof
properly completed and duly executed by or on behalf of the Holder, to the
Company at its office in Roseville, California (or at the office of the agency
maintained for such purpose), accompanied by payment in cash or by certified or
official bank check payable to the order of the Company, in an aggregate amount
equal to the Purchase Price as then adjusted times the number of shares of
Warrant Stock as to which this Warrant is then being exercised. In the event of
any such exercise that is partial, the Company shall endorse this Warrant as
having been exercised to that extent and return this Warrant to the Holder. This
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Warrant Stock issuable upon such
exercise shall be treated for all purposes as the holder of such shares of
record as of the close of business on such date.

               B. Net Issue Exercise. In lieu of exercising this Warrant
pursuant to Section 1.A, Holder may elect to receive shares equal to the value
of this Warrant (or the portion thereof being cancelled) by surrender of this
Warrant at such office together with notice of such election, in which event the
Company shall issue to Holder a number of shares of Warrant Stock computed using
the following formula:

                                 X = Y (A-B)
                                     ------
                                       A

Where X = the number of shares of Warrant Stock to be issued to Holder.

         Y  =  the number of shares of Warrant Stock purchasable under this
               Warrant at the date of such calculation or, if only a portion of
               this Warrant is being exercised, the portion of this Warrant
               being cancelled at the date of such calculation.

         A  =  the fair market value of one share of Warrant Stock purchasable
               under this Warrant at the date of such calculation.

         B  =  Purchase Price (as adjusted to the date of such calculations).

For purposes of this Warrant, fair market value of one share of Warrant Stock
shall mean:

               (1) The average of the closing bid and asked prices of the Common
Stock quoted on the NASDAQ Stock Market or the closing price quoted on any
national securities exchange on which the Common Stock is listed, whichever is
applicable, as published in the Western Edition of The Wall Street Journal for
the ten trading days prior to the date of determination of fair market value; or


<PAGE>   3

               (2) If the Common Stock is not traded on the NASDAQ stock market
or on such an exchange, an amount jointly determined by the Board of Directors
and the Holder, or in the event such persons are unable to reach agreement upon
such fair market value within 10 days of the exercise of this Warrant, the fair
market value as determined by an independent third-party appraiser jointly
selected by the Company's Board of Directors and the Holder hereof.

               C. Delivery of Stock Certificates. The Company will, or will
direct its transfer agent to, issue, as soon as practicable after any exercise
of this Warrant under Section 1 and in any event within thirty days thereafter,
at its expense (including the payment by it of any applicable issue taxes), in
the name of and deliver to the Holder, or as the Holder may direct (on payment
by the Holder of any applicable transfer taxes) a certificate or certificates
for the number of fully paid and nonassessable shares of Warrant Stock as to
which this warrant is so exercised.

        2. Payment of Taxes. All shares of Warrant Stock issued upon the
exercise of this Warrant shall be validly issued, fully paid and nonassessable,
and the Company shall pay all taxes and other governmental charges that may be
imposed in respect of the issuance or delivery thereof. The Company shall not be
required, however, to pay any tax or other charge imposed in connection with any
transfer involved in the issue of any certificate for shares of Warrant Stock in
any name other than that of the Holder and, in such case, the Company shall not
be required to issue or deliver any stock certificate until such tax or other
charge has been paid, or it has been established to the Company's satisfaction
that no tax or other charge is due.

        3. A. Transfer. Subject to Section 7, this Warrant and all rights
hereunder are transferable, as a whole or in part, on the books of the Company
maintained for such purpose at the office specified pursuant to Section 1.A, by
the Holder in person, or by duly authorized attorney, upon surrender of this
Warrant properly endorsed and upon payment of any necessary transfer tax or
other governmental charge imposed upon such transfer.

               Upon any partial transfer, the Company will issue and deliver to
the Holder a new warrant or warrants of like tenor with respect to the shares of
Warrant Stock not so transferred. In lieu of any fraction of a share to which
the Holder would otherwise be entitled, the Company may deliver to the Holder
cash in an amount equal to such fraction of the current fair market value of one
full share determined in the manner provided in Section 1.B.

               Each taker and holder of this Warrant, by taking or holding the
same, consents and agrees that this Warrant, when endorsed in blank, shall be
deemed negotiable and that when this Warrant shall have been so endorsed, the
person in possession of this Warrant may be treated by the Company, and all
other persons dealing with this Warrant, as the absolute owner hereof for any
purpose and as the person entitled to exercise the rights represented hereby,
any notice to the contrary notwithstanding, but until a transfer of this Warrant
on the books of the Company, the Company may treat the Holder as the owner for
all purposes.


<PAGE>   4

               B. Exchange. At the request of the Holder, the Company shall
exchange this Warrant for two or more Warrants of like tenor entitling the
Holder to purchase the same aggregate number of shares of Warrant Stock, each
new Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder shall designate at the time of such exchange; provided that
the Holder shall not be entitled so to exchange this Warrant or any warrant
received in any such exchange on more than an aggregate of seven occasions.

        4. A. Adjustment for Dividends in Other Stock or Property. In case at
any time, or from time to time, after the Issue Date the holders of the Common
Stock of the Company (or any shares of stock or other securities at the time
receivable upon the exercise of this Warrant), shall have received, or, on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive, without payment therefor:

               (1) Other or additional stock or other securities or property
(other than cash) by way of a dividend;

               (2) Any cash paid or payable out of capital, or capital surplus,
or surplus created as a result of a revaluation of property; or

               (3) Other or additional stock or other securities or property
(including cash) by way of a stock-split, spin-off, reclassification,
combination of shares or similar corporate rearrangement;

then, and in each such case, the Holder, upon the exercise hereof (as provided
in Section 1), shall be entitled to receive the number of shares of Warrant
Stock and other securities and property (including cash in the cases referred to
in clauses (2) and (3) above) which the Holder would hold on the date of such
exercise if on the Issue Date the Holder had been the holder of record of the
number of shares of Common Stock called for on the face of this Warrant and had
thereafter, during the period from the Issue Date to and including the date of
such exercise, retained such shares and/or all other or additional stock and
other securities and property (including cash in the cases referred to in
clauses (2) and (3) above) receivable by the Holder as aforesaid during such
period, giving effect to all adjustments during such period pursuant to this
Section 4.

               B. Merger, Sale of Assets, etc. If at any time while this
Warrant, or any portion thereof, is outstanding and unexpired there shall be (i)
a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), (ii) a merger or
consolidation of the Company with or into another corporation in which the
Company is not the surviving entity, or a reverse triangular merger in which the
Company is the surviving entity but the shares of the Company's capital stock
outstanding immediately prior to the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash, or
otherwise, or (iii) a sale or transfer of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the holder of this

<PAGE>   5

Warrant shall thereafter be entitled to receive upon exercise of this Warrant,
during the period specified herein and upon payment of the Purchase Price then
in effect, the number of shares of stock or other securities or property of the
successor corporation resulting from such reorganization, merger, consolidation,
sale or transfer that a holder of the shares deliverable upon exercise of this
Warrant would have been entitled to receive in such reorganization,
consolidation, merger, sale or transfer if this Warrant had been exercised
immediately before such reorganization, merger, consolidation, sale or transfer,
all subject to further adjustment as provided in this Section 4. The foregoing
provisions of this Section 4.B shall similarly apply to successive
reorganizations, consolidations, mergers, sales and transfers and to the stock
or securities of any other corporation that are at the time receivable upon the
exercise of this Warrant. If the per-share consideration payable to the holder
hereof for shares in connection with any such transaction is in a form other
than cash or marketable securities, then the value of such consideration shall
be determined in good faith by the Company's Board of Directors. In all events,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the Holder after the transaction, to
the end that the provisions of this Warrant shall be applicable after that
event, as near as reasonably may be, in relation to any shares or other property
deliverable after that event upon exercise of this Warrant.

               C. Reclassification, etc. If the Company, at any time while this
Warrant, or any portion hereof, remains outstanding and unexpired by
reclassification of securities or otherwise, shall change the Warrant Stock into
the same or a different number of securities of any other class or classes, this
Warrant shall thereafter represent the right to acquire such number and kind of
securities as would have been issuable as the result of such change with respect
to the Warrant Stock immediately prior to such reclassification or other change
and the Purchase Price therefor shall be appropriately adjusted, all subject to
further adjustment as provided in this Section 4.

               D. Split, Subdivision or Combination of Shares. If the Company at
any time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall split, subdivide or combine the Warrant Stock, into a different
number of securities of the same class, the Purchase Price for such securities
shall be proportionately decreased in the case of a split or subdivision or
proportionately increased in the case of a combination.

               E. Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment pursuant to this Section 4, the Company at its
expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to each Holder of this Warrant a certificate
setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The Company shall, upon the
written request, at any time, of any such Holder, furnish or cause to be
furnished to such Holder a like certificate setting forth: (i) such adjustments
and readjustments; (ii) the Purchase Price at the time in effect; and (iii) the
number of shares and the amount, if any, of other property that at the time
would be received upon the exercise of the Warrant.

               F. No Dilution or Impairment. The Company will not by amendment
of its Articles of Incorporation, or through reorganization, consolidation,
merger, dissolution, issuance or sale of securities, sale of assets, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the Holder against
dilution or other impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of Warrant Stock
receivable upon the exercise of this Warrant above the amount payable therefor
upon such exercise, (b) will take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares upon the exercise of this Warrant, and (c) will take no
action to amend its Articles of Incorporation which would change to the
detriment of the holders of Common Stock (whether or not any Common Stock be at
the time outstanding) the dividend or voting rights of the Company's Common
Stock (as constituted on the Issue Date).

               G.     Notices of Record Date.  In case:

               (1) The Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time receivable upon the exercise of
this Warrant) for the purpose of entitling them to receive any dividend or other
distribution or any right to subscribe for or purchase any shares of stock of
any class or any other securities, or to receive any other right, or

               (2) Of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any split or combination
of shares of any class of capital stock of the Company, any consolidation or
merger of the Company with or into another corporation, or any conveyance of all
or substantially all of the assets of the Company to another corporation, or

               (3) Of any voluntary dissolution, liquidation or winding-up of
the Company, then,

and in each such case, the Company will mail or cause to be mailed to the Holder
a notice specifying, as the case may be, (a) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (b) the date on
which such reorganization, reclassification, split, combination, consolidation,
merger, conveyance, dissolution, liquidation or winding-up is to take place, and
the time, if any is to be fixed, as of which the holders of record of Common
Stock (or such stock or securities at the time receivable upon the exercise of
this Warrant) shall be entitled to exchange their shares of Common Stock (or
such other stock or securities) for securities or other property deliverable
upon such reorganization, reclassification, split, combination, consolidation,
merger, conveyance, dissolution, liquidation or winding-up. Such notice shall be
mailed at least 90 days prior to the date therein specified.

<PAGE>   7
               H. Adjustments for Diluting Issuances. The Purchase Price and the
number of shares of Common Stock issuable upon exercise of this Warrant shall be
subject to adjustment from time to time in the manner set forth in the Holder's
Antidilution Agreement with the Company dated January 30, 1998.

        5. Loss or Mutilation. Upon receipt by the Company of evidence
reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of this Warrant, and of indemnity reasonably
satisfactory to it, and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver in lieu
thereof a new warrant of like tenor.

        6. Reservation of Common Stock. The Company shall at all times reserve
and keep available for issue upon the exercise of this Warrant such number of
its authorized but unissued shares of Warrant Stock as will be sufficient to
permit the exercise in full of this Warrant.

        7. Investment Intent. The Holder, by accepting this Warrant, represents
and warrants to the Company as follows:

               A. Acquisition for Own Account.  The Holder is acquiring this 
Warrant and will acquire the shares of Warrant Stock on exercise of this Warrant
with the Holder's own funds, for the Holder's own account, not as a nominee or
agent. The Holder is not obligated to transfer this Warrant or any Warrant Stock
to anyone else nor has any agreements or understandings to do so. The Holder is
purchasing or will purchase this Warrant and the Warrant Stock for investment
for an indefinite period and not with a view to any sale or distribution
thereof, by public or private sale or other disposition, and has no intention of
selling, granting any participation in or otherwise distributing or disposing of
any thereof. The Holder does not intend to subdivide the Holder's purchase with
anyone.

               B. Restricted Securities. The Holder is able to bear the economic
risk of the Holder's investment in this Warrant and the Warrant Stock and is
aware that the Holder must be prepared to hold this Warrant and the Warrant
Stock for an indefinite period and that this Warrant and the Warrant Stock have
not been registered under the Securities Act of 1933, as amended (the "Act"), on
the ground that no distribution or public offering of this Warrant or the
Warrant Stock is to be effected and this Warrant or the Warrant Stock are being
or will be issued by the Company without any public offering within the meaning
of Section 4(2) of the Act.

               C. Sophistication. The Holder is an "accredited investor" as that
term is defined in Regulation D under the Act. The Holder has such knowledge and
experience in financial and business matters that the Holder is capable of
evaluating the merits and risks of the Holder's investment in this Warrant and
the Warrant Stock.

               D. Agreement to Refrain from Resales. Without in any way limiting
the Holder's representations herein, the Holder further agrees that the Holder
shall not encumber,

<PAGE>   8

pledge, hypothecate, sell, assign, transfer or otherwise dispose of this Warrant
or any Warrant Stock, unless and until, prior to any proposed encumbrance,
pledge, hypothecation, sale, assignment, transfer or other disposition, either
(i) a registration statement on Form S-l (or any other form appropriate for the
purpose or replacing such form) under the Act with respect thereto shall be then
effective (ii)(a) the Holder shall have furnished the Company with a statement
of the circumstances of the proposed disposition and an opinion of counsel
(obtained at the Holder's expense) satisfactory to the Company to the effect
that such disposition will not require registration under the Act and (b)
counsel for the Company shall have concurred in such opinion of counsel and the
Company shall have advised the Holder of such concurrence; or (iii) the Warrant
Stock can then be sold pursuant to Rule 144 under the Act.

               E. Certificates to be Legended. The Holder understands and agrees
that this Warrant, any warrant issued to replace this Warrant and any
certificate representing Warrant Stock will bear a legend on the face thereof
(or on the reverse thereof with a reference to such legend on the face thereof)
in substantially the form set forth on the first page of this Warrant and any
other legend that the Company considers necessary or appropriate to comply with
any applicable securities law.

        8. Registration. The Company acknowledges that it has granted to certain
holders of its capital stock certain rights to registration of such capital
stock for resale under the Act, the terms and conditions of which rights are set
forth in an Investors' Rights Agreement dated as of September 30, 1997. The
Company covenants and agrees to seek an amendment to the Investors' Rights
Agreement to include the Warrant Stock in the Registrable Securities to which
the registration rights set forth in Section 1 of the Investors' Rights
Agreement so that the Holder shall be entitled to identical registration rights
pari passu with such holders of capital stock as if the Holder had acquired the
Warrant Stock concurrently with such holders and pursuant to the Investors'
Rights Agreement. If such amendment is not consented to by the holders of a
majority of the Registrable Securities as required by the Investors' Rights
Agreement, the Company shall promptly prepare and thereafter enter into with the
Holder a Registration Rights Agreement providing for the same registration
rights as the Investors' Rights Agreement, which rights shall be subject and
subordinate only to those set forth in the Investors' Rights Agreement.

        9. Notices. All notices and other communications from the Company to the
Holder shall be mailed by first-class registered or certified mail, postage
prepaid, to the address furnished to the Company in writing by the last Holder
who shall have furnished an address to the Company in writing.

        10. Change; Waiver. Neither this Warrant nor any term hereof may be
changed, waived, discharged or terminated orally but only by an instrument in
writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

<PAGE>   9

        11. Attorneys' Fees. In the event any party is required to engage the
services of attorneys for the purpose of enforcing this Warrant, or any
provision hereof, the prevailing party shall be entitled to recover its
reasonable attorneys' fees and any other costs or expenses.

        12. Headings. The headings in this Warrant are for purposes of
convenience in reference only, and shall not be deemed to constitute a part
hereof.

        13. Law Governing. This Warrant shall be construed and enforced in
accordance with and governed by the laws of the State of California.

        14. Conflict With Other Laws. Any other provisions hereof to the
contrary notwithstanding, no Bank Affiliate shall be entitled to exercise the
right under this Warrant to purchase any share or shares of the Common Stock if,
under any law or under any regulation, rule or other requirement of any
governmental authority at any time applicable to such Bank Affiliate, (a) as a
result of such purchase, such Bank Affiliate would own, control or have power to
vote a greater quantity of securities of any kind than the Bank Affiliate shall
be permitted to own, control or have power to vote, or (b) such purchase would
not be permitted. For purposes of this Section 14, a written statement of the
Bank Affiliate exercising this Warrant, delivered upon surrender of the Warrant,
to the effect that such Bank Affiliate is legally entitled to exercise its right
under this Warrant to purchase securities and that such purchase will not
violate the prohibitions set forth in the preceding sentence, shall be
conclusive and binding upon the Company and shall obligate the Company to
deliver certificates representing the shares of Common Stock so purchased in
accordance with the other provisions hereof and shall relieve the Company of any
liability under this Section 14. "Bank Affiliate" as used herein means any
person which is a bank holding company or a subsidiary of a bank holding company
as defined in the Bank Holding Company Act of 1956, as amended, or other
applicable banking laws of the United States of America and the rules and
regulations promulgated thereunder.

        15. Delivery of Financial Statements. The Company shall deliver to the
Holder:

               A. as soon as practicable, but in any event within one hundred
twenty (120) days after the end of each fiscal year of the Company, an income
statement for such fiscal year, a balance sheet of the Company and statement of
shareholder's equity as of the end of such year, and a statement of cash flows
for such year, such year-end financial reports to be in reasonable detail,
prepared in accordance with generally accepted accounting principles ("GAAP"),
and audited and certified by independent public accountants of nationally
recognized standing selected by the Company; and

               B. as soon as practicable, but in any event within sixty (60)
days after the end of each of the first three (3) quarters of each fiscal year
of the Company, an unaudited income statement for such fiscal quarter, statement
of cash flows for such fiscal quarter and an unaudited balance sheet as of the
end of such fiscal quarter.

<PAGE>   10

        16. Inspection. The Company shall permit the Holder, at the Holder's
expense, to visit and inspect the Company's properties, to examine its books of
account and records and to discuss the Company's affairs, finances and accounts
with its officers, all at such reasonable times as may be requested by the
Holder; provided, however, that the Company shall not be obligated pursuant to
this Section 16 to provide access to any information which it reasonably
considers to be a trade secret or similar confidential information.

                             WASTE CONNECTIONS, INC.
                             ANTIDILUTION AGREEMENT

        THIS ANTIDILUTION AGREEMENT is entered into as of January 30, 1998, by
and between FSC CORP. and WASTE CONNECTIONS, INC., a Delaware corporation (the
"Company").


                                    RECITALS

        A. Concurrently with the execution of this Antidilution Agreement, the
Company is issuing FSC Corp. a Warrant to purchase 140,000 shares (the "Shares")
of the Company's Common Stock (the "Common Stock") for $2.80 per share.

        B. By this Antidilution Agreement, FSC Corp. and the Company desire to
set forth the adjustment in the number of Shares issuable upon exercise of the
Warrant as a result of a diluting issuance.

        NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth, the parties hereto mutually agree as follows:

        1. Definitions. As used in this Antidilution Agreement, the following
terms have the following respective meanings:

            1.1 "Option" means any right, option, or warrant to subscribe for,
purchase, or otherwise acquire Common Stock or Convertible Securities.

            1.2 "Convertible Securities" means any evidences of indebtedness,
shares of stock, or other securities directly or indirectly convertible into or
exchangeable for Common Stock other than Options.

            1.3 "Issue" means to grant, issue, sell, assume, or fix a record
date for determining persons entitled to receive, any security, whichever of the
foregoing is the first to occur.

            1.4 "Additional Common Shares" means any of the Common Stock
(including reissued shares) issued after the date of the Warrant. Additional
Common Shares does not include, however, any Options; any Convertible
Securities; any Common Stock Issued upon conversion of preferred stock
outstanding on the date of the Warrant; the Shares; or Common Stock Issued as
incentive or in a nonfinancing transaction to employees, officers, directors, or
consultants to the Company; or the exercise of any Option or Convertible
Security.

        2. Adjustment of Warrant Price for Diluting Issuances.

            2.1 Weighted Average Adjustment. If the Company Issues Additional
Common Shares after the date of the Warrant and the consideration per Additional
Common 



<PAGE>   16

Share (determined pursuant to Section 4) is less than the Purchase Price (as
defined in the Warrant) in effect immediately before such Issue, the Purchase
Price in effect immediately before such Issue shall be reduced, concurrently
with such Issue, to a price (calculated to the nearest hundredth of a cent)
determined by multiplying the Purchase Price by a fraction:

                (a) the numerator of which is the amount of Common Stock
outstanding immediately before such Issue plus the amount of Common Stock that
the aggregate consideration received by the Company for the Additional Common
Shares would purchase at the Purchase Price in effect immediately before such
Issue, and

                (b) the denominator of which is the amount of Common Stock
outstanding immediately before such Issue plus the number of such Additional
Common Shares.

            2.2 Adjustment of Number of Shares. Upon each adjustment of the
Purchase Price, the number of Shares issuable upon exercise of the Warrant shall
be increased to equal the quotient obtained by dividing (a) the product
resulting from multiplying (i) the number of Shares issuable upon exercise of
the Warrant and (ii) the Purchase Price, in each case as in effect immediately
before such adjustment, by (b) the adjusted Purchase Price.

        3. No Adjustment for Issuances Following Deemed Issuances. No adjustment
to the Purchase Price shall be made upon the exercise of Options or conversion
of Convertible Securities.

        4. Computation of Consideration. The consideration received by the
Company for the Issue of any Additional Common Shares shall be computed as
follows:

            4.1 Cash shall be valued at the amount of cash received by the
Company, excluding amounts paid or payable for accrued interest or accrued
dividends.

            4.2 Property. Property other than cash shall be computed at the fair
market value thereof at the time of the Issue as determined in good faith by the
Board of Directors of the Company.

            4.3 Mixed Consideration. The consideration for Additional common
Shares Issued together with other property of the Company for consideration that
covers both shall be determined in good faith by the Board of Directors.

        5. General.

            5.1 Governing Law. This Antidilution Agreement shall be governed in
all respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

            5.2 Successors and Assigns. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.



                                       2
<PAGE>   17

            5.3 Entire Agreement. Except as set forth below, this Antidilution
Agreement and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof.

            5.4 Notices, etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be mailed by first class mail,
postage prepaid, certified or registered mail, return receipt requested,
addressed (a) if to FSC Corp. at FSC Corp.'s address as set forth below, or at
such other address as FSC Corp. shall have furnished to the Company in writing,
or (b) if to the Company, at the Company's address set forth below, or at such
other address as the Company shall have furnished to FSC Corp. in writing.

            5.5 Severability. In case any provision of this Antidilution
Agreement shall be invalid, illegal, or unenforceable, the validity, legality
and enforceability of the remaining provisions of this Antidilution Agreement
shall not in any way be affected or impaired thereby.

            5.6 Titles and Subtitles. The titles of the sections and subsections
of this Agreement are for convenience of reference only and are not to be
considered in construing this Antidilution Agreement.

            5.7 Counterparts. This Antidilution Agreement may be executed in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.

            5.8 Initial Public Offering. This Antidilution Agreement will be
void upon the consummation of a bona fide, firmly underwritten public offering
of shares of the Company's common stock registered under the Securities Act of
1933, as amended (the "Act"), pursuant to a registration statement on Form S-1,
at an offering price of at least $5.00 per share (appropriately adjusted for any
stock split, dividend, combination or other recapitalization) with aggregate
gross proceeds to the Company of at least $5,000,000.

concurrent with the Closing hereunder, certain solid waste assets in the states
of Washington and Idaho ("the Acquisition"). The Company is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
in which the ownership of its properties or the nature of its business make such
qualification necessary and where a failure to be so qualified would have a
material adverse effect on the business, operations, prospects or condition,
financial or otherwise, of the Company and its Subsidiaries taken as a whole
(the "Condition of the Company").

            2.2   Capitalization.

            (a) The Company has been recently formed and has not yet issued any

authorized, outstanding or contemplated any subscriptions, options, conversion
rights, warrants or other agreements, securities or commitments obligating the
Company to issue, deliver or sell, or cause to be issued, delivered or sold, any
shares of capital stock of the Company or any securities convertible into or
exchangeable for shares of capital stock of the Company or obligating the
Company to grant, extend or enter into any such agreement or commitment.

            (c) The designations, powers, preferences, rights, qualifications,
limitations and restrictions in respect of authorized capital stock of the
Company are as set forth in the Certificate of Designation, and all such
designations, powers, preferences, rights, qualifications,

authorized by all necessary corporate action on the part of the Company. The
Related Documents have been duly executed and delivered by the Company and the
Related Documents constitute legal, valid and binding agreements of the Company
enforceable against the Company in accordance with their respective terms,

the relief of debtors. The Series A Preferred Stock and the Common Stock will be
free of restrictions on transfer other than under applicable federal and state

            2.5 Absence of Conflicts. Neither the execution and delivery of the
Related Documents nor the consummation of the transactions contemplated hereby
or thereby nor the performance of or compliance with the terms and conditions in
the Related Documents will (a) violate any Law; (b) conflict with or result in a
breach or violation of or a default or loss of benefit under or permit the
acceleration of any obligation under any provision of the Certificate of

obtain and maintains or will maintain in full force and effect all permits,
licenses, consents, approvals, registrations, memberships, authorizations and
qualifications under all applicable Laws, and with all applicable Authorities,
required for the conduct by it of its businesses and the ownership or possession
by it of its properties and assets, except to the extent the failure to so

all respects with all Laws applicable to it or to the conduct by it of its
businesses or to its ownership and possession of its properties and assets,
except where the failure to so comply, does not, individually or in the

            2.9 Debt. Following the Closing of the Acquisition, the Company will
be indebted in the approximate amounts set forth on Schedule 2.9, which

            2.12 Registration Rights. Except as required pursuant to the
Investors' Rights Agreement, the Company is presently not under any obligation,
and has not granted any rights, to register (as defined in Section 1.1 of the
Investors' Rights Agreement) any of the Company's presently outstanding
securities or any of its securities that may hereafter be issued.

            2.13 Full Disclosure. This Agreement, the Exhibits hereto, the
Related Documents and all other documents delivered by the Company to the
Purchasers or their attorneys or agents in connection herewith or therewith at
the Closing or with the transactions contemplated hereby or thereby, do not
contain any untrue statement of a material fact, in the light of the
circumstances under which they were made, nor, to the Company's knowledge, omit
to state a material fact necessary in order to make the statements contained
herein or therein, in the light of the circumstances under which they were made,
not misleading. To the Company's knowledge, there are no facts which
(individually or in the aggregate) materially adversely affect the Condition of
the Company that have not been set forth in the Agreement, the Exhibits hereto,
the Related Documents or in other documents delivered to the Purchasers or their
attorneys or agents in connection herewith; provided that it is understood that
the level of disclosure to the Purchasers is less than that which would be
provided in a securities offering registered under the 1933 Act, including,
without limitation, the omission of risk factors, in reliance on the
sophistication and investment experience of the Purchasers.

            3. Representations and Warranties of the Purchasers. This Agreement
is made with each Purchaser in reliance upon that Purchaser's representations to
the Company, which by that Purchaser's acceptance hereof that Purchaser
severally, but not jointly, represents and warrants, that:

            3.1 Investment Intent. The Purchasers are acquiring the Series A
Preferred Stock and the Common Stock issuable hereunder or upon conversion of
the Series A Preferred Stock (collectively, "Securities") pursuant to this
Agreement with the Purchasers' own funds for the Purchasers' own account and not
as a nominee or agent. No one else has any interest, beneficial or otherwise, in
any of the Securities to be purchased by the Purchasers. Except as provided
herein, the Purchasers are not obligated to transfer any Securities to anyone
else nor do the Purchasers have any agreements or understandings to do so. The
Purchasers are purchasing the Securities for investment for an indefinite period
and not with a view to the sale or distribution of any Securities, by public or
private sale or other disposition, and the Purchasers have no intention of
selling, granting any participation in or otherwise distributing or disposing of
any Securities. The Purchasers do not intend to subdivide the Purchasers'
purchase of Securities with anyone. Notwithstanding the foregoing, the
disposition of the Purchasers' property shall be at all times within the
Purchasers' own control, and that the Purchasers' right to sell or otherwise
dispose of all or any part of the Securities purchased by the Purchasers
pursuant to an effective registration statement under the 1933 Act or under an
exemption 



                                       5
<PAGE>   7

available from such registration available under the 1933 Act shall not be
prejudiced; provided that the Purchasers comply with Section 6.11.

            3.2 No Public Offering. The Purchasers are able to bear the economic
risk of the Purchasers' investment in the Securities. The Purchasers are aware
that the Purchasers must be prepared to hold the Securities for an indefinite
period and that the Securities have not been registered under the 1933 Act or
registered or qualified under any state securities law, on the ground, among
others, that no distribution or public offering of Securities is to be effected
and Securities are being issued by the Company without any public offering
within the meaning of Section 4(2) of the 1933 Act. The Purchasers have had an
opportunity to discuss the Company's business, management and financial affairs
with its management. The Purchasers are not subscribing for the Securities as a
result of or subsequent to any advertisement, article, notice, or other
communication published in any newspaper, magazine or similar media or broadcast
over television or radio or any solicitation of a subscription by a person not
previously known to the Purchasers in connection with investments in securities
generally.

            3.3 Certificates to be Legended. The Purchasers understand that each
Security will bear a legend on the face thereof (or on the reverse thereof with
a reference to such legend on the face thereof) required by the Securities and
Exchange Commission or a state securities commission.

            3.4 Securities Will be "Restricted Securities". The Purchasers
understand that the Securities will be "restricted securities" as that term is
defined in Rule 144 under the 1933 Act and, accordingly, that the Securities
must be held indefinitely unless they are subsequently registered under the 1933
Act or an exemption from such registration is available. The Purchasers
understand and agree that except as provided herein the Company is not under any
obligation to register Securities under the 1933 Act or to comply with
Regulation A or any other exemption and that Rule 144 is not currently available
for sales of the Securities.

            3.5 Accredited Investor. The Purchasers have been advised or are
aware of the provisions of Regulation D under the 1933 Act relating to the
accreditation of investors, and by checking the appropriate boxes below, each of
the Purchasers represents that such Purchaser is an "accredited investor" as

Special Note for Trusts, Partnerships and Certain Plans: The application of the
"accredited investor" categories to trusts (including Massachusetts or similar
business trusts), partnerships and self-employed individual retirement plans is
subject to complex regulatory interpretations and may differ under state and
federal law. Accordingly, such an entity attempting to qualify may be required
to deliver additional information, including a satisfactory opinion of its
counsel.

knowledge and experience in financial and business matters that the Purchasers
are capable of evaluating the merits and risks of the Purchasers' investment

highly speculative and involves a substantial and high degree of risk of loss of
the Purchasers' entire investment. The Purchasers have adequate means of
providing for current and anticipated financial needs and contingencies, are
able to bear the economic risk for an indefinite period of time and have no need
for liquidity of the investment in the Securities and could afford complete loss
of such investment.

subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors.

                          INVESTORS' RIGHTS AGREEMENT


      THIS INVESTORS' RIGHTS AGREEMENT (this "Agreement") is made as of
September 30, 1997, by and among Waste Connections, Inc., a Delaware corporation
(the "Company"), and the investors listed on Exhibit A hereto, each of which is
herein referred to as an "Investor," with reference to the following facts:

      The Company and the Investors are parties to the Stock Purchase Agreement
dated as of September 30, 1997 (the "Stock Purchase Agreement") with respect to
the purchase of shares of Series A Preferred Stock (the "Series A Preferred
Stock") and Common Stock (the "Common Stock") of the Company. In order to induce
the Company to enter into the Stock Purchase Agreement and to induce the
Investors to invest funds in the Company pursuant to the Stock Purchase
Agreement, the Investors and the Company hereby agree that this Agreement shall
govern the rights of certain of the Investors to cause the Company to register
shares of Common Stock issuable to such Investors and certain other matters as
set forth herein.

      NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and conditions set forth in this Agreement, the parties agree as
follows:

      1.    Registration Rights.  The Company covenants and agrees as follows:

            1.1 Definitions. For purposes of this Agreement:

                  (a) The term "ACT" means the Securities Act of 1933, as
amended.

                  (b) The term "FORM S-3" means such form under the Act as in
effect on the date hereof or any registration form under the Act subsequently

information by reference to other documents filed by the Company with the SEC.

                  (c) The term "HOLDER" means any person owning or having the
right to acquire Registrable Securities or any assignee thereof in accordance
with Section 1.12.

                  (d) The term "1934 ACT" shall mean the Securities Exchange Act
of 1934, as amended.

                  (e) The term "PREFERRED STOCK" shall mean the Series A
Preferred Stock of the Company.

                  (f) The terms "REGISTER", "REGISTERED" and "REGISTRATION"
refer to a registration effected by preparing and filing a registration
statement or similar document in 


<PAGE>   5

compliance with the Act, and the declaration or ordering of effectiveness of
such registration statement or document.

                  (g) The term "REGISTRABLE SECURITIES" means the Common Stock
sold pursuant to the Stock Purchase Agreement, the Common Stock issued pursuant
to the Stock Purchase Agreement dated as of February 4, 1998, by and among Waste
Connections, Inc., Madera Disposal Systems, Inc., Alma Sciacqua, as trustee of
the Sciacqua Family Trust B, Eugene Dupreau, Melvin G. Dias, and Charles B.

Quinnan and Steven Bouck, the Common Stock issuable or issued upon conversion of
the Preferred Stock, and any other securities issued by the Company from time to
time that the Company's Board of Directors determines should be included in the
definition of "Registrable Securities", excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which his rights
under this Section 1 are not assigned; provided, however, that shares of Common
Stock or other securities shall not be treated as Registrable Securities for the
purposes of any registration if and so long as at the time of such registration
all transfer restrictions and restrictive legends with respect thereto have been
or, in the opinion of the Company's counsel, may be removed, and all the
Registrable Securities held by such Holder may be sold without restriction
(including any volume limitations) under Rule 144 under the Act.

                  (h) The number of shares of "REGISTRABLE SECURITIES THEN
OUTSTANDING" shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

                  (i) The term "SEC" shall mean the Securities and Exchange
Commission.

                  (j) The term "UNDERWRITTEN OFFERING" means an offering of
Common Stock to the public pursuant to an effective Registration Statement that
is firmly underwritten by a United States nationally recognized underwriter or
underwriters that are selected or approved by the Company in accordance with
this Agreement.

            1.2   Request for Registration.

                  (a) If the Company shall receive at any time after the earlier
of (i) four years after the Closing of the Series A Preferred Stock offering or
(ii) six (6) months after the effective date of the first registration statement
for a public offering of securities of the Company (other than a registration
statement relating either to the sale of securities to employees of the Company
pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145
transaction), a written request from Holders holding at least fifty percent
(50%) of the 


                                       2

<PAGE>   6

Registrable Securities then outstanding (the "Initiating Holders") that the
Company file a registration statement under the Act covering the registration of
at least twenty percent (20%) of the Registrable Securities then outstanding (or
a lesser percent if the anticipated aggregate offering price would exceed
$100,000,000), then the Company shall, within twenty-one (21) days after the
receipt thereof, give written notice of such request to all Holders and shall,
subject to the limitations and pursuant to the provisions of this Section 1.2,
use reasonable efforts to file a registration statement under the Act covering
all Registrable Securities which the Holders request to be registered.

                  (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action to effect any such registration pursuant to this
Section 1.2:

                        (i) if the Initiating Holders propose to dispose of
shares of Registrable Securities which may be immediately registered on Form S-3
pursuant to a request made under Section 1.11;

                        (ii) if the Holders shall have initiated two
registrations pursuant to this Section 1.2, which have been declared or ordered
effective and pursuant to which securities have been sold or have been withdrawn
by the Holders other than as a result of a material adverse change to the
Company; or

                        (iii) if the Company has effected a registration
pursuant to this Section 1.2 within one year prior to receipt of a requested
pursuant to Section 1.2(a).

                  (c)(i) Subject to the provisions of this Agreement, including,
but not limited to, the foregoing Section 1.2(b) and Section 1.4(a), the Company
shall file a registration statement as soon as practicable after receipt of the
request or requests of the Initiating Holders under this Section 1.2, but in any
event within ninety (90) days after receipt of such request or requests.

                  (ii) Notwithstanding anything to the contrary herein, the
Company shall not be obligated to effect a registration pursuant to this Section
1.2 during the period starting with the date approximately 10 days prior to the
Company's good faith estimate of the date of filing of, and ending on the date
six months following the effective date of, a Company-initiated registration
statement pertaining to the initial registered underwritten public offering of
securities for the Company's account (the "Initial Offering"); provided that the
Company makes reasonable good faith efforts to cause such registration statement
to become effective.

                  (d) The right of any Holder to registration pursuant to this
Section 1.2 shall be conditioned on such Holder's participation in an
Underwritten Offering and the inclusion of such Holder's Registrable Securities
to be registered in the Underwritten Offering. The Company shall (together with
all Holders proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the underwriter or


                                       3
<PAGE>   7


underwriters selected by the Company, which underwriter or underwriters shall be
reasonably acceptable to a majority in interest of the Initiating Holders.
Notwithstanding any other provision of this Section 1.2, if the underwriters
advise the Initiating Holders and the Company in writing that marketing factors
require a limitation of the number of shares to be underwritten and that the
total amount of securities that all Holders (initiating and noninitiating)
request pursuant to this Section 1.2(d) to be included in such offering exceeds
the amount of securities that the underwriters reasonably believe compatible
with the success of the offering, the Company shall so advise all Holders and
all of the Holders' shares to be included in the registration shall be allocated
among all Holders requesting inclusion (initiating and noninitiating) pro rata
according to the total amount of securities entitled to be included in such
registration owned by each Holder requesting inclusion (initiating or
noninitiating) or in such other proportions as shall be mutually agreed by such
selling shareholders. Shares of Registrable Securities held by the Holders shall
not be subject to cutback following the allocation unless shares of all other
selling shareholders have been eliminated from the offering.

            If any Holder does not agree to the terms of any such underwriting,
that person shall be excluded therefrom by written notice from the Company or
the underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. If
shares are so withdrawn from the registration and the number of shares of
Registrable Securities to be included in such registration was previously
reduced as a result of marketing factors, the Company shall then offer to all
persons who have retained the right to include securities in the registration
the right to include additional securities in the registration in an aggregate
amount equal to the number of shares so withdrawn, with such shares to be
allocated among the persons requesting additional inclusion pro rata according
to the total amount of securities entitled to be included in such registration
owned by each such person or in such other proportions as shall be mutually
agreed by such selling shareholders. For purposes of the preceding sentence
concerning apportionment, for any selling shareholder which is a holder of
Registrable Securities and which is a partnership, limited liability company or
corporation, the partners, retired partners, members, retired members and
shareholders of such holder, or the estates and family members of any such
partners, retired partners, members, retired members and shareholders and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "selling shareholder," and any pro-rata reduction with respect to such
"selling shareholder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "selling shareholder," as defined in this sentence.

            1.3 Company Registration. If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company for any shareholders) any of its stock or other
securities under the Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company stock plan, a registration on
any form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities or a registration in which the 



                                       4
<PAGE>   8

only Common Stock being registered is Common Stock issuable upon conversion of
debt securities which are also being registered), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty (20) days after mailing of
such notice by the Company in accordance with Section 3.7, the Company shall,
subject to the provisions of Section 1.7, cause to be registered under the Act
all of the Registrable Securities that each such Holder has requested to be
registered.

            1.4 Obligations of the Company. Whenever required under this Section
1 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for a period of up to one hundred twenty
(120) days or until the distribution contemplated in the Registration Statement
has been completed; provided, however, that (i) such 120-day period shall be
extended for a period of time equal to the period the Holder refrains from
selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company; and (ii) in
the case of any registration of Registrable Securities on Form S-3 which are
intended to be offered on a continuous or delayed basis, such 120-day period
shall be extended, if necessary, to keep the registration statement effective
until all such Registrable Securities are sold, provided that Rule 415, or any
successor rule under the Act, permits an offering on a continuous or delayed
basis, and provided further that applicable rules under the Act governing the
obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (i) includes any prospectus required by Section
10(a)(3) of the Act or (ii) reflects facts or events representing a material or
fundamental change in the information set forth in the registration statement,
the incorporation by reference of information required to be included in (i) and
(ii) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the 1934 Act in the registration statement. Notwithstanding anything to
the contrary in this Agreement, the Company may delay filing a Registration
Statement, and may withhold efforts to cause a Registration Statement to become
effective, for a period not to exceed 120 days, if the Company shall furnish to
Holders a certificate signed by the Chairman of the Board stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration
statement to be effected at such time; provided that such right to delay a
request shall be exercised by the Company not more than once in any twelve (12)
month period. If, after a Registration Statement becomes effective, the Company
advises the holders of registered shares that the Company considers it
appropriate for the Registration Statement to be amended or supplemented, the
holders of such shares shall suspend any further sales of their registered
shares, for a period not to exceed 90 days, until the Company advises them that
the registration statement has been amended or updated.



                                       5
<PAGE>   9

                  (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

                  (c) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                  (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions.

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                  (f) Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

                  (g) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

                  (h) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

            1.5 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.



                                       6
<PAGE>   10

            1.6 Expenses of Company Registration. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to this Section 1 for each Holder (which right may be assigned as
provided in Section 1.12), including (without limitation) all registration,
filing, and qualification fees, printers and accounting fees relating or
apportionable thereto and the fees and disbursements of counsel for the Company
and one separate counsel for the selling Holders hereunder (selected by the
Holders of a majority of the Registrable Securities that are included in the
corresponding registration), but excluding underwriting discounts and
commissions relating to Registrable Securities.

            1.7 Underwriting Requirements. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under this Section 1 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not,
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities that the underwriters
determine in good faith is compatible with the success of the offering, the
number of shares that may be included in the underwriting shall be allocated,
first, to the Company; second, to the Holders on a pro rata basis based on the
total number of Registrable Securities held by the Holders; and third, to any
shareholder of the Company (other than a Holder) on a pro rata basis. No such
reduction shall reduce the amount of securities of the selling Holders included
in the registration below fifteen percent (15%) of the total amount of
securities included in such registration, unless such offering is the Initial
Offering and such registration does not include shares of any other selling
shareholders, in which event any or all of the Registrable Securities of the
Holders may be excluded in accordance with the immediately preceding sentence.
In no event will shares of any other selling shareholder be included in such
registration which would reduce the number of shares which may be included by
Holders without the written consent of Holders of not less than two-thirds (66
2/3%) of the Registrable Securities proposed to be sold in the offering.

            If any Holder does not agree to the terms of any such underwriting,
the holder shall be excluded therefrom by written notice from the Company or the
underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. If
shares are so withdrawn from the registration and or if the number of shares of
Registrable Securities to be included in such registration was previously
reduced as a result of marketing factors, the Company shall then offer to all
persons who have retained the right to include securities in the registration
the right to include additional securities in the registration in an aggregate
amount equal to the number of shares so withdrawn, with such shares to be
allocated among the persons requesting additional inclusion pro rata according
to the total amount of securities entitled to be included in such registration
owned by each such person or in such other proportions as shall be mutually
agreed by such selling shareholders. For 



                                       7
<PAGE>   11

purposes of the preceding sentence concerning apportionment, for any selling
shareholder which is a holder of Registrable Securities and which is a
partnership, limited liability company or corporation, the partners, retired
partners, members, retired members and shareholders of such holder, or the
estates and family members of any such partners, retired partners, members,
retired members and shareholders and any trusts for the benefit of any of the
foregoing persons shall be deemed to be a single "selling shareholder," and any
pro-rata reduction with respect to such "selling shareholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling shareholder," as defined in
this sentence.

            1.8 Delay of Registration. No Holder shall have any right to obtain
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

            1.9 Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 1:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (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, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person, as incurred, any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
contained in this subsection 1.9(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person of
such Holder.

                  (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the 



                                       8
<PAGE>   12

registration statement, each person, if any, who controls the Company within the
meaning of the Act, any underwriter, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or
other Holder, against any losses, claims, damages or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Act, the 1934 Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereto) arise out of or are based
upon any Violation, in each case to the extent (and only to the extent) that
such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 1.9(b), in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.9(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided, that, in no event shall any
indemnity under this subsection 1.9(b) exceed the net proceeds from the offering
received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
Section 1.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.9, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1,9, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.9.

                  (d) If the indemnification provided for in this Section 1.9 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that 




                                       9
<PAGE>   13

resulted in such loss, liability, claim, damage or expense as well as any other
relevant equitable considerations. The relative fault of the indemnifying party
and of the indemnified party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

                  (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                  (f) The obligations of the Company and Holders under this
Section 1.9 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

            1.10 Reports Under Securities Exchange Act of 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

                  (c) furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

            1.11 Form S-3 Registration. In case the Company shall receive
written request or requests from at least ten percent (10%) of the Holders of
the Registrable Securities that the 



                                       10
<PAGE>   14

Company effect a registration on Form S-3 and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

                  (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders; and

                  (b) as soon as practicable, effect such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within 20
days after effectiveness of such written notice from the Company pursuant to
Section 3.7; provided, however, that the Company shall not be obligated to
effect any such registration, qualification or compliance pursuant to this
Section 1.11: (i) if Form S-3 is not available for such offering by the Holders;
(ii) if the Holders, together with the holders of any other securities of the
Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at any aggregate price to the
public less than $1,000,000; or (iii) as provided in Section 1.4(a) or Section
1.4(d).

                  (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. Registrations effected pursuant to this
Section 1.11 shall not be counted as demands for registration effected pursuant
to Section 1.2.

            1.12 Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Section 1 may be
assigned to a transferee or assignee (other than a competitor of the Company)
who acquires at least twenty-five percent (25%) of the shares held by a Holder
provided: (a) the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; (b) such transferee or assignee agrees in writing to be bound by
and subject to the terms and conditions of this Agreement and the Stockholders
Agreement, including without limitation the provisions of Section 1.13 below;
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act; and (d) transfer of registration rights to
a limited or general partner of any Holder that is a partnership will be without
restriction as to minimum shareholding. For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee, the
holdings of transferees and assignees of a partnership or limited liability
company who are partners or retired partners of such partnership or members or
retired members of such limited liability company (including spouses and
ancestors, lineal descendants and siblings of such partners, members or spouses
who acquire Registrable Securities by gift, will or intestate 



                                       11
<PAGE>   15

succession) shall be aggregated together and with the partnership or limited
liability company; provided that all assignees and transferees who would not
qualify individually for assignment of registration rights shall have a single
attorney-in-fact for the purpose of exercising any rights, receiving notices or
taking any action under this Section 1.

            1.13 "Market Stand-Off" Agreement. Each Investor hereby agrees that,
during the period of duration specified by the Company and an underwriter of
Common Stock or other securities of the Company, following the effective date of
a registration statement filed under the Act for the first public offering of
the Company's Common Stock, it shall not, to the extent requested by the Company
and such underwriter, directly or indirectly sell, offer to sell, contract to
sell (including, without limitation, any short sale), grant any option to
purchase or otherwise transfer or dispose of (other than to donees who agree to
be similarly bound) any securities of the Company held by it at any time during
such period except Common Stock included in such registration; provided,
however, that:

                  (a) all officers and directors of the Company, all holders of
Common Stock and options to purchase Common Stock and all other persons with
registration rights (whether or not pursuant to this Agreement) enter into
similar agreements; and

                  (b) such market stand-off time period shall not exceed 180
days.

            In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

            Notwithstanding the foregoing, the obligations described in this
Section 1.13 shall not apply to a registration relating solely to employee
benefit plans on Form S-1 or Form S-8 or similar forms which may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-14 or Form 915 or similar forms which may be promulgated
in the future.

            1.14  Termination of Registration Rights.

                  (a) No Holder shall be entitled to exercise any right provided
for in this Section 1 after five (5) years following the consummation of the
sale of securities pursuant to a registration statement filed by the Company
under the Act in connection with the Initial Offering.

                  (b) In addition, the right of any Holder to request
registration or inclusion in any registration pursuant to Section 1 shall
terminate on the closing of the first Company-initiated registered public
offering of Common Stock of the Company if all shares of Registrable Securities
held or entitled to be held upon conversion by such Holder may 



                                       12
<PAGE>   16

immediately be sold under Rule 144 during any 90 day period, or on such date
after the closing of the first Company-initiated registered public offering of
Common Stock of the Company as all shares of Registrable Securities held or
entitled to be held upon conversion by such Holder may immediately be sold under
Rule 144 during any 90 day period.

            1.15 Registration of Common Stock. For purposes of Section 1 of this
Agreement, the only securities which the Company shall be required to register
pursuant hereto shall be shares of Common Stock, provided, however, that, in any
underwritten public offering contemplated by Section 1 hereof, the holders of
Preferred Stock shall be entitled to sell such Preferred Stock to the
underwriters for conversion and sale of the shares of Common Stock issued upon
conversion thereof.

      2. Covenants of the Company.

            2.1 Delivery of Financial Statements. The Company shall deliver to
each holder of Series A Preferred Stock (or Common Stock issued upon conversion
of Series A Preferred Stock):

                  (a) as soon as practicable, but in any event within one
hundred twenty (120) days after the end of each fiscal year of the Company, an
income statement for such fiscal year, a balance sheet of the Company and
statement of shareholder's equity as of the end of such year, and a statement of
cash flows for such year, such year-end financial reports to be in reasonable
detail, prepared in accordance with generally accepted accounting principles
("GAAP"), and audited and certified by independent public accountants of
nationally recognized standing selected by the Company; and

                  (b) as soon as practicable, but in any event within sixty (60)
days after the end of each of the first three (3) quarters of each fiscal year
of the Company, an unaudited income statement for such fiscal quarter, statement
of cash flows for such fiscal quarter and an unaudited balance sheet as of the
end of such fiscal quarter.

            2.2 Inspection. The Company shall permit each Investor, at such
Investor's expense, to visit and inspect the Company's properties, to examine
its books of account and records and to discuss the Company's affairs, finances
and accounts with its officers, all at such reasonable times as may be requested
by the Investor; provided, however, that the Company shall not be obligated
pursuant to this Section 2.2 to provide access to any information which it
reasonably considers to be a trade secret or similar confidential information.

            2.3 Right of First Offer. Subject to the terms and conditions
specified in this Section 2.3, the Company hereby grants to each Investor a
right of first offer with respect to future sales by the Company of its Shares
(as hereinafter defined). For purposes of this Section 2.3, Investor includes
any general partners, managers and affiliates of an Investor. An 



                                       13
<PAGE>   17

Investor shall be entitled to apportion the right of first offer hereby granted
it among itself and its partners, members and affiliates in such proportions as
it deems appropriate.

                  Each time the Company proposes to offer any shares of, or
securities convertible into or exercisable for any shares of, any class of its
capital stock ("Shares"), the Company shall first make an offering of such
Shares to each Investor in accordance with the following provisions:

                  (a) The Company shall deliver a notice by certified mail
("Notice") to the Investors stating (i) its bona fide intention to offer such
Shares, (ii) the number of such Shares to be offered, and (iii) the price and
terms, if any, upon which it proposes to offer such Shares.

                  (b) By written notification received by the Company, within 20
calendar days after giving of the Notice, the Investor may elect to purchase or
obtain, at the price and on the terms specified in the Notice, up to that
portion of such Shares which equals the proportion that the number of shares of
common stock issued and held, or issuable upon conversion of the Preferred Stock
then held by such Investor bears to the total number of shares of common stock
of the Company then outstanding (assuming full conversion and exercise of all
convertible or exercisable securities). The Company shall promptly, in writing,
inform each Investor which purchases all the shares available to it
("Fully-Exercising Investor") of any other Investor's failure to do likewise.
During the ten-day period commencing after such information is given, each
Fully-Exercising Investor shall be entitled to obtain that portion of the Shares
for which Investors were entitled to subscribe but which were not subscribed for
by the Investors which is equal to the proportion that the number of shares of
common stock issued and held, or issuable upon conversion of Preferred Stock
then held by such Fully-Exercising Investor bears to the total number of shares
of common stock issued and held, or issuable upon conversion of the Preferred
Stock then held, by all Fully-Exercising Investors who wish to purchase some of
the unsubscribed shares.

                  (c) If all Shares which Investors are entitled to obtain
pursuant to subsection 2.3(b) are not elected to be obtained as provided in
subsection 2.3(b) hereof, the Company may, during the 60-day period following
the expiration of the period provided in subsection 2.3(b) hereof, offer the
remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than those
specified in the Notice. If the Company does not enter into an agreement for the
sale of the Shares within such period, or if such agreement is not consummated
within 30 days of the execution thereof, the right provided hereunder shall be
deemed to be revived and such Shares shall not be offered unless first reoffered
to the Investors in accordance herewith.

                  (d) The right of first offer in this Section 2.3 shall not be
applicable (i) to consummation of a bona fide, firmly underwritten public
offering of shares of common stock registered under the Act pursuant to a
registration statement on Form S-1, at an offering price of 



                                       14
<PAGE>   18

at least $5.00 per share (appropriately adjusted for any stock split, dividend,
combination or other recapitalization) with aggregate gross proceeds to the
Company of at least $5,000,000, (ii) the issuance of securities pursuant to the
conversion or exercise of convertible or exercisable securities, (iii) the
issuance of securities in connection with a bona fide business acquisition of or
by the Company, whether by merger, consolidation, sale of assets, sale or
exchange of stock or otherwise, or (iv) the issuance of options or warrants to
purchase shares of Common Stock to officers, directors and employees of, or
consultants to, the Company, with an exercise price greater than the then
current conversion price of the Company's Series A Preferred Stock.

                  (e) The right of first offer set forth in this Section 2.3 may
be assigned or transferred to the same parties, subject to the same restrictions
pursuant to Section 1.12.

            2.4 Termination of Certain Covenants. The covenants set forth in
this Section 2 shall terminate and be of no further force or effect upon the
consummation of a bona fide, firmly underwritten public offering of shares of
Common Stock registered under the Act pursuant to a registration statement on
Form S-1, at an offering price of at least $5.00 per share (appropriately
adjusted for any stock split, dividend, combination or other recapitalization)
with aggregate gross proceeds to the Company of at least $5,000,000.

      3.    Miscellaneous.

            3.1 Restrictive Legend. Each certificate representing Preferred
Stock or Common Stock issued upon conversion thereof shall, except as otherwise
provided in Section 3.2, be stamped or otherwise imprinted with a legend
substantially in the following form:

            THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
            1933 OR ANY STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED OR
            OTHERWISE DISPOSED OF UNLESS IT HAS BEEN REGISTERED UNDER SUCH ACT
            AND ALL SUCH OTHER APPLICABLE LAWS OR AN EXEMPTION FROM REGISTRATION
            IS AVAILABLE.

A certificate shall not bear such legend if in the opinion of counsel
satisfactory to the Company the securities being sold thereby may be publicly
sold without registration under the Act and any applicable state securities
laws.

            3.2 Notice of Proposed Transfer. Prior to any proposed transfer of
any Preferred Stock or Common Stock issued upon conversion thereof (other than
under the circumstances described in Section 1), the holder thereof shall give
written notice to the Company of his or her intention to effect such transfer.
Each such notice shall describe the manner of the proposed transfer and, if
reasonably requested by the Company, shall be accompanied by an opinion of
counsel satisfactory to the Company to the effect that the proposed transfer may
be effected without registration under the Act and any applicable state
securities 



                                       15
<PAGE>   19

laws, whereupon the holder of such stock shall be entitled to transfer such
stock in accordance with the terms of the notice; provided, however, that no
such opinion of counsel shall be required for a transfer to one or more partners
or members of the transferor (in the case of a transferor that is a partnership
or limited liability company) or to an affiliated corporation (in the case of a
transferor that is a corporation). Each certificate for Preferred Stock or
Common Stock issued upon conversion thereof transferred as above provided shall
bear the legend set forth in Section 3.1, except that such certificate shall not
bear such legend if (i) such transfer is in accordance with the provisions of
Rule 144 (or any other rule permitting public sale without registration under
the Act) or (ii) the opinion of counsel referred to above is to the further
effect that the transferee and any subsequent transferee (other than an
affiliate of the Company) would be entitled to transfer such securities in a
public sale without registration under the Act. The restrictions provided for in
this Section 3.2 shall not apply to securities which are not required to bear
the legend prescribed by Section 3.1 in accordance with the provisions of that
Section.

            3.3 Successors and Assigns. Except as otherwise provided herein, the
terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the respective successors and assigns of the parties (including
transferees of any shares of Registrable Securities). Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement.

            3.4 Governing Law. This Agreement shall be governed by and construed
and interpreted in accordance with the laws of the State of California, without
regard to that state's conflict of laws principles.

            3.5 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.

            3.6 Titles and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

            3.7 Notices. Any notice, consent, authorization or other
communication to be given hereunder shall be in writing and shall be deemed duly
given and received when delivered personally or transmitted by facsimile
transmission with receipt acknowledged by the addressee or three days after
being mailed by first class mail, or the next business day after being deposited
for next-day delivery with a nationally recognized overnight delivery service,
charges and postage prepaid, properly addressed to the party to receive such
notice at the following address for such party (or at such other address as
shall be specified by like notice):

                                                                   EXHIBIT 10.9

                             STOCKHOLDERS AGREEMENT


      THIS STOCKHOLDERS AGREEMENT ("Agreement") is entered into as of September
30, 1997, by and among Waste Connections, Inc., a Delaware corporation (the
"Company"), the persons named on Exhibit A attached to this Agreement, each of
whom is a holder of shares of Series A Preferred Stock of the Company (each a
"Series A Preferred Stockholder") or a holder of shares of Common Stock of the
Company (each a "Common Stockholder"), (the Series A Preferred Stockholders and
the Common Stockholders sometimes shall be hereinafter collectively referred to
as "Investors"), with reference to the following facts:

      As of the date of this Agreement, certain of the Series A Preferred
Stockholders have acquired 2,500,000 shares of Series A Preferred Stock of the
Company and certain of the Common Stockholders have acquired 2,500,000 shares of
Common Stock of the Company pursuant to the terms of the Stock Purchase
Agreement (the "Purchase Agreement") among the Series A Preferred Stockholders,
the Common Stockholders and the Company. It is a condition to the closing of the
transactions contemplated by the Purchase Agreement that this Agreement be
executed by the parties hereto.

      NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and conditions set forth in this Agreement, the parties agree as
follows:

      1. Voting Agreement. Each of the Investors hereby agrees with respect to
the election of directors of the Company that upon request of the holders of at
least 50% of the outstanding shares of Series A Preferred Stock of the Company,
the Investors shall vote the shares of the Company's stock then owned by them in
favor of the number of Series A Nominees (the "Series A Nominees") listed below
opposite the then applicable authorized number of directors, which nominees
shall be nominated by the holders of at least 50% of the outstanding shares of
Series A Preferred Stock of the Company:

                   Authorized Number
                      of Directors              Series A Nominees

</TABLE>

      If at the time such request is made, the authorized number of directors is
five or fewer, the Board of Directors of the Company shall promptly amend the
Bylaws of the Company to increase the number of directors to a number that would
allow the number of Series A Nominees derived from the above table to be
elected, and then shall promptly elect the Series A Nominees selected by the
holders of at least 50% of the outstanding shares of Series A Preferred Stock of


                                       1
<PAGE>   2

the Company to fill the vacancies created by such increase in the authorized
number of directors. If at the time such request is made, the authorized number
of directors exceeds five, the Board of Directors of the Company shall promptly
amend the Bylaws of the Company to increase the number of directors to nine, and
one or more of the directors then in office shall resign so that the number of
directors then in office is five. Following such resignations, the Board of
Directors shall elect four Series A Nominees selected by the holders of at least
50% of the outstanding shares of Series A Preferred Stock of the Company to fill
the vacancies created by such increase. If any director refuses to resign after
being asked to do so by the Board, each of the Investors hereby agrees to vote
the shares of the Company's stock then owned by such Investor for the removal of
such director.

      2.    Co-Sale Agreement.

            2.1   Definitions.

            (a) "Co-Sale Shares" shall mean shares of the Company's Common Stock
and securities convertible (other than the Preferred Stock) into, exchangeable
for, or exercisable for, Common Stock now owned or subsequently acquired by the
Investors. The number of Co-Sale Shares relating to a convertible security shall
be the number of shares of Common Stock of the Company into which such security
is convertible, exchangeable or exercisable.

            (b) "Preferred Stock" shall mean the Series A Preferred Stock of the
Company.

            2.2   Sales by a Stockholder.

            (a) Except for certain sales and gifts permitted by Section 3, if
any of the Investors or Permitted Transferees (as defined below) proposes to
sell or transfer any Co-Sale Shares (any one of such Investors and Permitted
Transferees being hereinafter sometimes called the "Transferring Stockholder"),
then the Transferring Stockholder shall promptly give written notice (the
"Co-Sale Notice") to the Company and to each of the Investors at least 20 days
prior to the closing of such sale or transfer. The Co-Sale Notice shall describe
in reasonable detail the proposed sale or transfer including, without
limitation, the number of Co-Sale Shares to be sold or transferred, the nature
of such sale or transfer, the consideration to be paid, and the name and address
of each prospective purchaser or transferee. In the event that the sale or
transfer is being made pursuant to the provisions of Section 3 hereof, the
Co-Sale Notice shall state under which subparagraph the sale or transfer is
being made.

            (b) With respect to a proposed transfer by a Transferring
Stockholder, the Investors shall have the right, exercisable upon written notice
to the Transferring Stockholder within 15 days after receipt of the Co-Sale
Notice, to participate in such sale on the same terms and conditions specified
in the Co-Sale Notice. To the extent that Investors exercise such right 

                                       2
<PAGE>   3

of participation in accordance with the terms and conditions set forth below,
the number of Co-Sale Shares that the Transferring Stockholder may sell in the
transaction shall be reduced.

            (c) Each Investor may sell all or any part of that number of Co-Sale
Shares at the same price per share and on the same terms and conditions as
involved in the sale by the Transferring Stockholder equal to the total number
of shares to be sold in the transaction multiplied by a fraction, the numerator
of which is the number of Co-Sale Shares held by such Investor and the
denominator of which is the total number of Co-Sale Shares outstanding.

            (d) Each Investor to participate in the right of co-sale (a
"Participant") shall effect his, her or its participation in the sale by
promptly delivering to the Transferring Stockholder for transfer to the
prospective purchaser one or more certificates, properly endorsed for transfer,
which represent:

                  (i) the number of Co-Sale Shares which such Participant elects
to sell; or

                  (ii) that number of shares of Series A Preferred Stock which
is at such time convertible into the number of Co-Sale Shares which such
Participant elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Series A Preferred Stock in lieu of Co-Sale Shares,
such Participant shall convert such Series A Preferred Stock into Co-Sale Shares
and deliver Co-Sale Shares as provided above. The Company agrees to make any
such conversion concurrent with the actual transfer of such shares to the
purchaser.

            (e) The stock certificate or certificates that the Participant
delivers to the Transferring Stockholder pursuant to Section 2.2(d) shall be
transferred to the prospective purchaser in consummation of the sale of the
Co-Sale Shares pursuant to the terms and conditions specified in the Co-Sale
Notice, and the Transferring Stockholder shall concurrently therewith remit to
such Participant the sale proceeds to which such Participant is entitled by
reason of his, her or its participation in such sale. To the extent that any
prospective purchaser or purchasers prohibits such assignment or otherwise
refuses to purchase shares or other securities from a Participant exercising
his, her or its rights of co-sale hereunder, the Transferring Stockholder shall
not sell to such prospective purchaser or purchasers any Co-Sale Shares unless
and until, simultaneously with such sale, the Transferring Stockholder shall
purchase such shares or other securities from such Participant.

            (f) The exercise or non-exercise of the rights of the Participants
hereunder to participate in one or more sales of Co-Sale Shares made under this
Agreement shall not adversely affect their rights to participate in subsequent
sales of Co-Sale Shares subject to this Agreement.

            (g) If none of the Investors elects to participate in the sale of
the Co-Sale Shares subject to the Co-Sale Notice, the Transferring Stockholder
may, not later than sixty (60) days following delivery to the Company and each
of the Investors of the Co-Sale Notice, enter 

                                       3
<PAGE>   4

into an agreement providing for the closing of the transfer of the Co-Sale
Shares covered by the Co-Sale Notice within thirty (30) days after the date of
such agreement on terms and conditions not more favorable to the Transferring
Stockholder than those described in the Co-Sale Notice. Any proposed transfer on
terms and conditions more favorable than those described in the Co-Sale Notice,
as well as any subsequent proposed transfer of any of the Co-Sale Shares by an
Investor, shall again be subject to the co-sale rights of the other Investors
and shall require compliance with the procedures described in this Section 2.2.

            (h) Any Co-Sale Shares sold pursuant to this Section 2.2 shall no
longer be subject to this Agreement.

      3.    Exempt Transfers.

            (a) Notwithstanding the foregoing, the provisions of Section 2 shall
not apply to (i) any transfer to the ancestors, descendants or spouse or to
trusts for the benefit of a Transferring Stockholder; or (ii) any bona fide gift
by an Investor; provided that (A) the Transferring Stockholder shall inform the
Investors of such transfer or gift prior to effecting it and (B) the transferee
or donee shall furnish the Investors with a written agreement to be bound by and
comply with all provisions of this Agreement, the Investors' Rights Agreement
and the Stock Purchase Agreement. Such transferred Co-Sale Shares shall remain
"Co-Sale Shares" hereunder and such transferee or donee shall be treated as a
"Transferring Stockholder" and as an "Investor". In addition, notwithstanding
the foregoing, the provisions of Section 2.2 shall not apply to any transfers
from an Investor to a partner, active or retired of an Investor, the estate of
any such partner or a parent or subsidiary corporation of an Investor, or a
corporation which has the same parent corporation as an Investor provided that
such Investor notifies the other Stockholders prior to effecting the transfer
and the transferee shall furnish the Stockholders with a written agreement to be
bound by and comply with all provisions of this Agreement, the Investors' Rights
Agreement and the Stock Purchase Agreement. Such transferred shares shall remain
"Co-Sale Shares" hereunder and such transferee (a "Permitted Transferee") shall
be treated as an additional "Transferring Stockholder" for purposes of this
Agreement.

            (b) Notwithstanding the foregoing, the provisions of Section 2 of
this Agreement shall not apply to the sale of any Co-Sale Shares (i) to the
public pursuant to a registration statement filed with, and declared effective
by, the Securities and Exchange Commission under the Securities Act of 1933, as
amended (the "Securities Act") or (ii) to the Company on termination of the
employment of a Transferring Stockholder pursuant to the terms of any agreement
between that Transferring Stockholder and the Company or as otherwise approved
by the Board of Directors of the Company.

      4.    Prohibited Transfers.

            (a) In the event a Transferring Stockholder should sell any Co-Sale
Shares in contravention of the co-sale rights of the Investors under this
Agreement (a "Prohibited Transfer"), each Investor who had co-sale rights in
connection with the Prohibited Transfer, in addition to such other remedies as
may be available at law, in equity or hereunder, shall have the put option
provided below, and the Transferring Stockholder shall be bound by the
applicable provisions of such option.

            (b) In the event of a Prohibited Transfer, each Investor shall have
the right to sell to the Transferring Stockholder the type and number of shares
of Co-Sale Shares equal to the number of shares each Investor would have been
entitled to transfer to the purchaser had the Prohibited Transfer been effected
pursuant to and in compliance with the terms of Section 2.2 this Agreement. Such
sale shall be made on the following terms and conditions:

                  (i) The price per share at which the shares are to be sold to
the Transferring Stockholder shall be equal to the price per share paid by the
purchaser to the Transferring Stockholder in the Prohibited Transfer. The
Transferring Stockholder shall also reimburse each Investor for any and all fees
and expenses, including legal fees and expenses, incurred pursuant to the
exercise or the attempted exercise of the Investor's rights under Section 2.2.

                  (ii) Within 90 days after the later of the dates on which the
Investor (A) received notice of the Prohibited Transfer or (B) otherwise became
aware of the Prohibited Transfer, each Investor shall, if exercising the option
created hereby, deliver to the Transferring Stockholder the certificate or
certificates representing shares to be sold, each certificate to be properly
endorsed for transfer.

                  (iii) The Transferring Stockholder shall, upon receipt of the
certificate or certificates for the shares to be sold by an Investor, pursuant
to this Section 4(b), pay the aggregate purchase price therefor and the amount
of reimbursable fees and expenses, as specified in Section 4(b)(i), in cash or
by other means acceptable to the Investor.

            (c) Notwithstanding the foregoing, any attempt by a Transferring
Stockholder to transfer Co-Sale Shares in violation of Section 2.2 hereof shall
be void and the Company agrees it will not effect such a transfer nor will it
treat any alleged transferee as the holder of such shares without the prior
written consent of a majority-in-interest of the Investors.

      5. Further Assurances. The parties shall do or perform any and all such
further acts and things and execute and deliver any and all such documents and
instruments as may be reasonably necessary to carry out the provisions of this
Agreement. Exercise of the parties' rights under this Agreement shall be subject
to and conditioned upon, and each Transferring

                                       5
<PAGE>   6
Stockholder, Investor and the Company shall use their best efforts to assist
each Transferring Stockholder in, compliance with applicable laws.

      6. Spousal Consents. Any natural person to whose benefit this Agreement
may now or hereafter inure shall use his or her best efforts to obtain the
acknowledgment and consent of his or her spouse, whether such party is now
married or marries or remarries hereafter, in substantially the form attached
hereto following the signature page hereof.

      7. Stop Transfer Instructions. The parties agree that stop order
instructions prohibiting transfer of certificates for Shares will be issued and
filed by the Company on its records or with the Company's transfer agent to
prevent any disposition otherwise than strictly in accordance with this
Agreement and agree to cause the officers of the Company to refuse to record on
the books of the Company any assignments or transfers made or attempted to be
made except in accordance with this Agreement and to cause said officers to
refuse to cancel certificates, or issue or deliver new certificates therefor,
where the purchaser, assignee, pledgee, donee or other transferee has acquired
certificates or any Shares represented thereby otherwise than strictly in
accordance with this Agreement.

      8. Additional Stockholders. If the Company shall at any future time desire
to issue or reissue Shares to any Investor, all such issuees shall become
parties to this Agreement (and their spouses shall acknowledge and consent
thereto as provided in Section 6) with respect to such Shares by executing a
writing agreeing to be bound hereby.

      9. Legend. Each certificate representing shares of stock now or hereafter
owned by any Permitted Transferee shall include the following legend:

      THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER AND THE VOTING OF THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
      CONDITIONS OF A CERTAIN STOCKHOLDERS AGREEMENT, BY AND BETWEEN THE
      STOCKHOLDER, THE CORPORATION AND CERTAIN HOLDERS OF STOCK OF THE
      CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST
      TO THE SECRETARY OF THE CORPORATION.

      10. Repurchase Agreement. This Stockholder Agreement is subject to, and
shall in no manner limit the right of the Company to repurchase securities from
an Investor pursuant to any stock restriction agreement or other agreement
between the Company and the Investor.

      11. Ownership. Each Transferring Stockholder represents and warrants that
such Transferring Stockholder is the sole legal and beneficial owner of the
shares of stock subject to this Agreement and that no other person has any
interest (other than a community property interest) in such shares.

                              EMPLOYMENT AGREEMENT



         THIS EMPLOYMENT AGREEMENT is made and effective as of October 1, 1997,
by and between Ronald J. Mittelstaedt (the "Employee"), Waste Connections, Inc.,
a Delaware corporation (the "Company"), and J. Bradford Bishop, Frank W. Cutler
and James N. Cutler, Jr. (the "Founders"), with reference to the following
facts.

        The Company desires to engage the services and employment of the
Employee for the period provided in this Agreement, and the Employee is willing
to accept employment by the Company for such period, on the terms and conditions
set forth below.

         NOW THEREFORE, in consideration of the premises and the mutual
covenants and conditions herein, the Company and the Employee agree as follows:

         1. Employment. The Company agrees to employ the Employee, and the
Employee agrees to accept employment with the Company, for the Term stated in
Section 3 hereof and on the other terms and conditions herein.

         2. Position and Responsibilities. During the Term, the Employee shall
serve as Chief Executive Officer and President of the Company, and perform such
other duties and responsibilities as the Board of Directors (the "Board") of the
Company may reasonably assign to the Employee from time to time. In addition,
the Employee shall serve as a member of the Board for an initial term of three
(3) years beginning on the date hereof. While the Employee is a member of the
Board, he shall serve on the Executive and Finance Committees of the Board. The
Employee shall devote such time and attention to his duties as are necessary to
the proper discharge of his responsibilities hereunder. The Employee agrees to
perform all duties consistent with (a) policies established from time to time by
the Company and (b) all applicable legal requirements.

         3. Term. The period of the Employee's employment under this Agreement
shall commence on the effective date of this Agreement and shall continue
through September 30, 2002, unless terminated earlier as provided herein or
extended by the vote of a majority of the Board (the "Term"). At the end of the
Term, this Agreement shall be renewed automatically for successive periods of
one year, unless either party shall have given the other notice of termination
hereof as provided herein.

         4. Compensation, Benefits and Reimbursement of Expenses.

               (a) Compensation. The Company shall compensate the Employee
during the Term of this Agreement as follows:


                                        1

<PAGE>   2



                           (1) Base Salary. The Employee shall be paid a base
salary ("Base Salary") of not less than One Hundred Seventy Thousand Dollars
($170,000) per year in installments consistent with the Company's usual
practices. The Board shall review the Employee's Base Salary on October 1 of
each year or more frequently, at the times prescribed in salary administration
practices applied generally to management employees of the Company. In addition,
if an IPO Closing (as defined below) with respect to the Company's Common Stock
occurs on or before October 1, 1998, the Employee's Base Salary shall be
adjusted on October 1, 1998, to the greater of (i) Two Hundred Fifty Thousand
Dollars ($250,000) per year, or (ii) the average of the annual base salaries of
Chief Executive Officers of comparable small- to mid-cap solid waste management
companies as determined and approved by the Board. An "IPO Closing" means (x)
the date the shares of the Company's Common Stock issued in an initial public
offering registered under the Securities Act of 1933, as amended (an "IPO"), are
sold to the underwriter, if the IPO is a fully underwritten offering, or (y) the
day following the closing of the Company's IPO, if the IPO is a best efforts
offering.

                           (2) Performance Bonus. The Employee shall be entitled
to an annual cash bonus (the "Bonus") based on the Company's attainment of
reasonable financial objectives to be determined annually by the Board. The
maximum annual Bonus will equal one hundred percent (100%) of the applicable
year's ending Base Salary and will be payable if a majority of the Board
determines, in its sole and exclusive discretion, that that year's financial
objectives have been fully met. Notwithstanding the foregoing, the Employee will
receive an aggregate minimum Bonus of One Hundred Twenty-Five Thousand Dollars
($125,000) for the 15-month period ending December 31, 1998, if the following
conditions are met:

                                    (i) If by December 31, 1998, the Company
consummates the acquisition of another company or companies or businesses with
aggregate annual revenues of at least $10,000,000 (for this purpose, the annual
revenues of each such company or business acquired shall equal its revenues in
the most recent four full quarters before the acquisition), the Employee shall
receive a Bonus of at least Seventy-Five Thousand Dollars ($75,000), to be paid
in installments; each installment shall be paid within 30 days after the closing
of such an acquisition and shall be in an amount equal to the product of $75,000
multiplied by a fraction, the numerator of which is the annual revenues of the
company or business acquired, and the denominator of which is $10,000,000.

                                    (ii) If the Company's income before
interest, depreciation and taxes for the six-month period ending March 31, 1998,
is at least $1,475,754, the Employee shall receive a Bonus of at least $25,000
by April 15, 1998. In addition, if the Company's income before interest,
depreciation and taxes for the twelve-month period ending September 30, 1998, is
at least $3,016,841, the Employee shall receive an additional Bonus of at least
$25,000 by October 15, 1998; provided, that if the Company's income before
interest, depreciation and taxes for the six-month period ending March 31, 1998,
is less than $1,475,754 but for the 

                                       2
<PAGE>   3

twelve-month period ending September 30, 1998 is at least $3,016,841, the
Employee shall receive a Bonus of at least $50,000 by October 15, 1998.

                  The Bonus with respect to fiscal years beginning after
December 31, 1998 shall be paid in accordance with the Company's bonus plan, as
approved by the Board; provided that in no case shall any portion of the Bonus
with respect to any such fiscal year be paid more than seventy-five (75) days
after the end of such fiscal year.

                  (b) Other Benefits. During the Term, the Employee shall be
entitled to a vehicle allowance of Five Thousand Dollars ($5,000) per year net
after payment of all taxes. In addition, the Company shall pay or reimburse the
Employee for all fuel and maintenance on Employee's vehicle. During the Term,
the Company shall provide the Employee with a cellular telephone and will pay or
reimburse the Employee's monthly service fee and costs of calls attributable to
Company business. During the Term, the Company will also pay for the cost of a
fax line to Employee's residence. During the Term, the Employee shall be
entitled to receive all other benefits of employment generally available to
other management employees of the Company and those benefits for which
management employees are or shall become eligible, including, without limitation
and to the extent made available by the Company, medical, dental, disability and
prescription coverage, life insurance and tax-qualified retirement benefits. The
Employee shall be entitled to four (4) weeks of paid vacation each year of his
employment.

                  (c) Reimbursement of Other Expenses. The Company agrees to pay
or reimburse the Employee for all reasonable travel and other expenses incurred
by the Employee in connection with the performance of his duties under this
Agreement on presentation of proper expense statements or vouchers. All such
supporting information shall comply with all applicable Company policies
relating to reimbursement for travel and other expenses.

                  (d) Withholding. All compensation payable to the Employee
hereunder is subject to all withholding requirements under applicable law.

         5. Confidentiality. During the Term of his employment, and at all times
thereafter, the Employee shall not, without the prior written consent of the
Company, divulge to any third party or use for his own benefit or the benefit of
any third party or for any purpose other than the exclusive benefit of the
Company, any confidential or proprietary business or technical information
revealed, obtained or developed in the course of his employment with the Company
and which is otherwise the property of the Company or any of its affiliated
corporations, including, but not limited to, trade secrets, customer lists,
formulae and processes of manufacture; provided, however, that nothing herein
contained shall restrict the Employee's ability to make such disclosures during
the course of his employment as may be necessary or appropriate to the effective
and efficient discharge of his duties to the Company.


                                       3
<PAGE>   4

         6. Property. Both during the Term of his employment and thereafter, the
Employee shall not remove from the Company's offices or premises any Company
documents, records, notebooks, files, correspondence, reports, memoranda and
similar materials or property of any kind unless necessary in accordance with
the duties and responsibilities of his employment. In the event that any such
material or property is removed, it shall be returned to its proper file or
place of safekeeping as promptly as possible. The Employee shall not make,
retain, remove or distribute any copies, or divulge to any third person the
nature or contents of any of the foregoing or of any other oral or written
information to which he may have access, except as disclosure shall be necessary
in the performance of his assigned duties. On the termination of his employment
with the Company, the Employee shall leave with or return to the Company all
originals and copies of the foregoing then in his possession or subject to his
control, whether prepared by the Employee or by others.

         7. Termination By Company.

                  (a) Termination for Cause. The employment of the Employee may
be terminated for Cause at any time by the vote of a majority of the Board;
provided, however, that before the Company may terminate the Employee's
employment for Cause for any reason that is susceptible to cure, the Company
shall first send the Employee written notice of its intention to terminate this
Agreement for Cause, specifying in such notice the reasons for such Cause and
those conditions that, if satisfied by the Employee, would cure the reasons for
such Cause, and the Employee shall have 60 days from receipt of such written
notice to satisfy such conditions. If such conditions are satisfied within such
60-day period, the Company shall so advise the Employee in writing. If such
conditions are not satisfied within such 60-day period, the Company may
thereafter terminate this Agreement for Cause on written Notice of Termination
(as defined in Section 9(a)) delivered to the Employee describing with
specificity the grounds for termination. Immediately on termination pursuant to
this Section 7(a), the Company shall pay to the Employee in a lump sum his then
current Base Salary under Section 4(a)(1) on a prorated basis to the Date of
Termination (as defined in Section 9(b)). On termination pursuant to this
Section 7(a), the Employee shall forfeit (i) his Bonus under Section 4(a)(2) for
the year in which such termination occurs, and (ii) all unvested ISOs, other
stock options, warrants and rights relating to capital stock of the Company. For
purposes of this Agreement, Cause shall mean:

                           (1) a material breach of any of the terms of this
Agreement that is not immediately corrected following written notice of default
specifying such breach;

                           (2) repeated intoxication with alcohol or drugs while
on Company premises during its regular business hours to such a degree that, in
the reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

                           (3) conviction of a felony; or

                                       4
<PAGE>   5

                           (4) misappropriation of property belonging to the
Company and/or any of its affiliates.

                  (b) Termination Without Cause. The employment of the Employee
may be terminated without Cause at any time by the vote of a majority of the
Board on delivery to the Employee of a written Notice of Termination (as defined
in Section 9(a)). On the Date of Termination (as defined in Section 9(b))
pursuant to this Section 7(b), the Company shall pay to the Employee in a lump
sum an amount equal to the sum of (i) all Base Salary payable under Section
4(a)(1) through the termination date, (ii) a pro-rated portion of the maximum
Bonus available to the Employee under Section 4(a)(2) for the year in which the
termination occurs, and (iii) an amount equal to three times the Total
Compensation paid to the Employee by the Company with respect to the twelve
months preceding the termination date. For purposes of this section 7(b), the
Employee's Total Compensation shall equal the sum of the Base Salary, Bonus,
vehicle allowance and other benefits and expense reimbursements described in
Section 4(b), and director's fees paid to the Employee by the Company. If the
Employee is terminated without Cause before the first anniversary of the
effective date of this Agreement, the Total Compensation paid to the Employee
through the termination date shall be annualized before calculating the amount
in clause (iii) above. In addition, on termination of the Employee under this
Section 7(b), all of the Employee's unvested ISOs, other stock options, warrants
and rights relating to capital stock of the Company shall immediately vest and
become exercisable. The term of any such options, warrants and rights shall be
extended to the fifth anniversary of the Employee's termination. The Employee
acknowledges that extending the term of any incentive stock option pursuant to
this Section 7(b), or Section 7(c), 7(d) or 8(a), could cause such option to
lose its tax-qualified status under the Internal Revenue Code of 1986, as
amended (the "Code"), and agrees that the Company shall have no obligation to
compensate the Employee for any additional taxes he incurs as a result.

                  (c) Termination on Disability. If during the Term the Employee
should fail to perform his duties hereunder on account of physical or mental
illness or other incapacity which the Board shall in good faith determine
renders the Employee incapable of performing his duties hereunder, and such
illness or other incapacity shall continue for a period of more than six (6)
consecutive months ("Disability"), the Company shall have the right, on written
Notice of Termination (as defined in Section 9(a)) delivered to the Employee to
terminate the Employee's employment under this Agreement. During the period that
the Employee shall have been incapacitated due to physical or mental illness,
the Employee shall continue to receive the full Base Salary provided for in
Section 4(a)(1) hereof at the rate then in effect until the Date of Termination
(as defined in Section 9(b)) pursuant to this Section 7(c). On the Date of
Termination pursuant to this Section 7(c), the Company shall pay to the Employee
in a lump sum an amount equal to (i) the Base Salary remaining payable to the
Employee under Section 4(a)(1) for the full remaining Term, plus (ii) a
pro-rated portion of the maximum Bonus available to the Employee under Section
4(a)(2) for the year in which the termination occurs. In addition, on 

                                       5
<PAGE>   6

such termination, all of the Employee's unvested ISOs, other stock options,
warrants and rights relating to capital stock of the Company shall immediately
vest and become exercisable. The term of any such options, warrants and rights
shall be extended to the fifth anniversary of the Employee's termination.

                  (d) Termination on Death. If the Employee shall die during the
Term, the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof. In
addition, on termination of the Employee under this Section 7(d), all of the
Employee's unvested ISOs, other stock options, warrants and rights relating to
capital stock of the Company shall immediately vest and become exercisable. The
term of any such options, warrants and rights shall be extended to the fifth
anniversary of the Employee's termination. The provisions of this Section 7(d)
shall not affect the entitlements of the Employee's heirs, executors,
administrators, legatees, beneficiaries or assigns under any employee benefit
plan, fund or program of the Company.

         8. Termination By Employee.

                  (a) Termination for Good Reason. The Employee may terminate
his employment hereunder for Good Reason (as defined below). On the Date of
Termination pursuant to this Section 8(a), the Employee shall be entitled to
receive, and the Company agrees to pay and deliver, the payments and other
benefits applicable to termination without Cause set forth in Section 7(b)
hereof. In addition, on termination of the Employee under this Section 8(a), all
of the Employee's unvested ISOs, other stock options, warrants and rights
relating to capital stock of the Company shall immediately vest and become
exercisable. The term of any such options, warrants and rights shall be extended
to the fifth anniversary of the Employee's termination.

                  For purposes of this Agreement, "Good Reason" shall mean:

                           (1) assignment to the Employee of duties inconsistent
with his responsibilities as they existed on the date of this Agreement; a
substantial alteration in the title(s) of the Employee (so long as the existing
corporate structure of the Company is maintained); or a substantial alteration
in the status of the Employee in the Company organization as it existed on the
date of this Agreement;

                           (2) the relocation of the Company's principal
executive office to a location more than fifty (50) miles from its present
location;

                           (3) a reduction by the Company in the Employee's Base
Salary;

<PAGE>   7

                           (4) a failure by the Company to continue in effect,
without substantial change, any benefit plan or arrangement in which the
Employee was participating or the taking of any action by the Company which
would adversely affect the Employee's participation in or materially reduce his
benefits under any benefit plan (unless such changes apply equally to all other
management employees of Company);

                           (5) any material breach by the Company of any
provision of this Agreement without the Employee having committed any material
breach of his obligations hereunder, which breach is not cured within twenty
(20) days following written notice thereof to the Company of such breach; or

                           (6) the failure of the Company to obtain the
assumption of this Agreement by any successor entity.

                  (b) Termination Without Good Reason. The Employee may
terminate his employment hereunder without Good Reason on written Notice of
Termination delivered to the Company setting forth the effective date of
termination. If the Employee terminates his employment hereunder without Good
Reason, he shall be entitled to receive, and the Company agrees to pay on the
effective date of termination specified in the Notice of Termination, his
current Base Salary under Section 4(a)(1) hereof on a prorated basis to such
date of termination. On termination pursuant to this Section 8(b), the Employee
shall forfeit (i) his Bonus under Section 4(a)(2) for the year in which such
termination occurs, and (ii) all unvested ISOs, other stock options, warrants
and rights relating to capital stock of the Company.

         9. Provisions Applicable to Termination of Employment.

                  (a) Notice of Termination. Any purported termination of
Employee's employment by the Company pursuant to Section 7 shall be communicated
by Notice of Termination to the Employee as provided herein, and shall state the
specific termination provisions in this Agreement relied on and set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment ("Notice of Termination"). If the
Employee terminates under Section 8, he shall give the Company a Notice of
Termination.


                                       7

<PAGE>   8

               (b) Date of Termination. For all purposes, "Date of Termination"
shall mean, for Disability, thirty (30) days after Notice of Termination is
given to the Employee (provided the Employee has not returned to duty on a
full-time basis during such 30-day period), or, if the Employee's employment is
terminated by the Company for any other reason or by the Employee, the date on
which a Notice of Termination is given.

               (c) Benefits on Termination. On termination of this Agreement by
the Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

         10. Change In Control.

               (a) Payments on Change in Control. Notwithstanding any provision
in this Agreement to the contrary, unless the Employee elects in writing to
waive this provision, a Change in Control (as defined below) of the Company
shall be deemed a termination of the Employee without Cause, and the Employee
shall be entitled to receive and the Company agrees to pay to the Employee in a
lump sum the same amount determined under Section 7(b) that is payable to the
Employee on termination without Cause. In addition, on a Change of Control, all
of the Employee's unvested ISOs, other stock options, warrants and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and the term of any such options, warrants and rights shall be
extended to the fifth anniversary of the Employee's termination.

               After a Change in Control, if any option, warrant or right (the
"Terminated Option") relating to the Company's capital stock does not remain
outstanding, the successor to the Company or its then Parent (as defined below)
shall either:

                           (i) Issue an option, warrant or right, as appropriate
(the "Successor Option"), to purchase common stock of such successor or Parent
in an amount such that on exercise of the Successor Option the Employee would
receive the same number of shares of the successor's/Parent's common stock as
the Employee would have received had the Employee exercised the Terminated
Option immediately prior to the transaction resulting in the Change in Control
and received shares of such successor/Parent in such transaction. The aggregate
exercise price for all of the shares covered by such Successor Option shall
equal the aggregate exercise price of the Terminated Option; or

                           (ii) Pay the Employee a bonus within ten (10) days
after the consummation of the Change in Control, in an amount agreed to by the
Employee and the Company. Such amount shall be at least equivalent on an
after-tax basis to the net after-tax gain that the Employee would have realized
if he had been issued a Successor Option under clause (i) above 

                                       8
<PAGE>   9

and had immediately exercised such Successor Option and sold the underlying
stock, taking into account the different tax rates that apply to such bonus and
to such gain, and such amount shall also reflect other differences to the
Employee between receiving a bonus under this clause (ii) and receiving a
Successor Option under clause (i) above.

                  (b) Definitions. For the purposes of this Agreement, a Change
in Control shall be deemed to have occurred if (i) there shall be consummated
(aa) any reorganization, liquidation or consolidation of the Company, or any
merger or other business combination of the Company with any other corporation,
other than any such merger or other combination that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or if
(ii) any "person" (as defined in Section 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), shall become the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of fifty percent (50%) or more of the Company's outstanding
voting securities (except that for purposes of this Section 10(b), "person"
shall not include any person (or any person that controls, is controlled by or
is under common control with such person) who as of the date of this Agreement
owns ten percent (10%) or more of the total voting power represented by the
outstanding voting securities of the Company, or a trustee or other fiduciary
holding securities under any employee benefit plan of the Company, or a
corporation that is owned directly or indirectly by the stockholders of the
Company in substantially the same percentage as their ownership of the Company)
or if (iii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the entire Board shall cease for any reason
to constitute at least one-half of the membership thereof unless the election,
or the nomination for election by the Company's shareholders, of each new
director was approved by a vote of at least one-half of the directors then still
in office who were directors at the beginning of the period.

             The term "Parent" means a corporation, partnership, trust, limited
liability company or other entity that is the ultimate "beneficial owner" (as
defined above) of fifty percent (50%) or more of the Company's outstanding
voting securities.

         11. Gross Up Payments. If all or any portion of any payment or benefit
that the Employee is entitled to receive from the Company pursuant to this
Agreement (a "Payment") constitutes an "excess parachute payment" within the
meaning of Section 280G of the Code, and as such is subject to the excise tax
imposed by Section 4999 of the Code or to any similar Federal, state or local
tax or assessment (the "Excise Tax"), the Company or its successors or assigns
shall pay to the Employee an additional amount (the "Gross-Up Payment") with
respect to such Payment. The amount of the Gross-Up Payment shall be sufficient
that, after paying (a) 

                                       9
<PAGE>   10

any Excise Tax on the Payment, (b) any Federal, state or local income or
employment taxes and Excise Tax on the Gross-Up Payment, and (c) any interest
and penalties imposed in respect of the Excise Tax, the Employee shall retain an
amount equal to the full amount of the Payment. For the purpose of determining
the amount of any Gross-Up Payment, the Employee shall be deemed to pay Federal
income taxes at the highest marginal rate applicable in the calendar year in
which the Gross-Up Payment is made, and state and local income taxes at the
highest marginal rate applicable in the state and locality where the Employee
resides on the date the Gross-Up Payment is made, net of the maximum reduction
in Federal income taxes that could be obtained from deducting such state and
local taxes.

             The Gross-Up Payment with respect to any Payment shall be paid to
the Employee within ten (10) days after the Internal Revenue Service or any
other taxing authority issues a notice stating that an Excise Tax is due with
respect to the Payment, unless the Company undertakes to challenge the taxing
authority on the applicability of such Excise Tax and indemnifies the Employee
for (a) any amounts ultimately determined to be payable, including the Excise
Tax and any related interest and penalties, (b) all expenses (including
attorneys' and experts' fees) reasonably incurred by the Employee in connection
with such challenge, as such expenses are incurred, and (c) all amounts that the
Employee is required to pay to the taxing authorities during the pendency of
such challenge (such amounts to be repaid by the Employee to the Company if they
are ultimately refunded to the Employee by the taxing authority).

         12. Indemnification. As an employee and agent of the Company, the
Employee shall be fully indemnified by the Company to the fullest extent
permitted by applicable law in connection with his employment hereunder. In
addition, the Company shall pay all legal costs and expenses reasonably incurred
by the Employee (including attorneys' and expert witness fees), as such expenses
are incurred, in defending against any claim by United Waste Systems, Inc.
("United"), or USA Waste Services, Inc., that by entering into and performing
under this Agreement the Employee has violated any provision of his previous
employment or consulting agreement with United prohibiting competition, use of
confidential information, or solicitation of employees or prospective customers;
provided that the Company shall not be liable for any other damages that the
Employee incurs in connection with such a claim, including any amount the
Employee pays to settle such a claim or to satisfy a judgment in connection with
such a claim.

         13. Board Representation. The Company agrees that during the Term,
beginning on the date that the personal guarantees of Brad Bishop, Frank Butler,
Jim Butler and the Employee to Imperial Bank with respect to indebtedness of the
Company are removed, the Employee may recommend nominees for election to the
Board, such that at all times that there are five (5) or fewer members of the
Board, the Employee shall have recommended at least two (2) nominees for
election to such Board, and at all times that there are more than five (5)
members of the Board, the Employee shall have recommended at least three (3)
nominees for election to such Board.

  
                                       10
<PAGE>   11

         14. Additional Equity Investment by the Employee. On the date of this
Agreement, the Company shall sell to the Employee, for $0.01 per share in cash,
617,500 shares of the Company's Common Stock, which amount is equal to 12.35% of
the Company's total initial authorized number of shares of Common and Preferred
Stock (such number of total initial authorized shares of Common and Preferred
Stock is called the "Total Initial Shares").

             In addition, the Employee agrees, concurrently with the date of
this Agreement, to purchase a number of shares of Series A Preferred Stock of
the Company equal to seven and one-eighth percent (7.125%) of the Company's
Total Initial Shares, for consideration in the amount of One Million Dollars
($1,000,000), in the form of a cashier's check payable to the Company.

             The Company agrees that if on January 1, 1998, the Employee desires
to sell shares of Series A Preferred Stock of the Company and has not yet
obtained a commitment from a buyer on terms satisfactory to the Employee, the
Company will use its best efforts to obtain additional equity financing, which
shall be used to purchase from the Employee shares of the Company's Series A
Preferred Stock representing three and nine-sixteenths percent (3.5625%) of the
Company's Total Initial Shares, for cash consideration to the Employee in the
amount of Five Hundred Thousand Dollars ($500,000).

         15. Management Stock Pool. The Company agrees that at the IPO Closing,
the Company shall reserve at least eight percent (8%) of the Company's Total
Initial Shares (or, if the number of shares of Common Stock issued in the IPO
exceeds the number included in the Total Initial Shares, the Company's Total
Initial Shares plus such excess) for issuance to management employees of the
Company pursuant to stock options and warrants. Such options and warrants shall
be issued to management employees from time to time as approved by a majority of
the Board, for the purposes of recruiting, retaining and motivating such
management employees.

         16. Survival of Provisions. The obligations of the Company under
Section 12 of this Agreement shall survive both the termination of the
Employee's employment and this Agreement.

         17. No Duty to Mitigate; No Offset. The Employee shall not be required
to mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

         18. Assignment; Binding Agreement. The Company may assign this
Agreement to any parent, subsidiary, affiliate or successor of the Company. This
Agreement is not assignable by the Employee and is binding on him and his
executors and other legal representatives. This

                                       11
<PAGE>   12

Agreement shall bind the Company and its successors and assigns and inure
to the benefit of the Employee and his heirs, executors, administrators,
personal representatives, legatees or devisees. The Company shall assign this
Agreement to any entity that acquires its assets or business.

         19. Notice. Any written notice under this Agreement shall be personally
delivered to the other party or sent by certified or registered mail, return
receipt requested and postage prepaid, to such party at the address set forth in
the records of the Company or to such other address as either party may from
time to time specify by written notice.

         20. Entire Agreement; Amendments. This Agreement contains the entire
agreement of the parties relating to the Employee's employment and supersedes
all oral or written prior discussions, agreements and understandings of every
nature between them. This Agreement may not be changed except by an agreement in
writing signed by the Company and the Employee.

         21. Waiver. The waiver of a breach of any provision of this Agreement
shall not operate or as be construed to be a waiver of any other provision or
subsequent breach of this Agreement.

         22. Governing Law and Jurisdictional Agreement. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of California.

         23. Severability. In case any one or more of the provisions contained
in this Agreement is, for any reason, held invalid in any respect, such
invalidity shall not affect the validity of any other provision of this
Agreement, and such provision shall be deemed modified to the extent necessary
to make it enforceable.

         24. Enforcement. It is agreed that it is impossible to measure fully,
in money, the damage which will accrue to the Company in the event of a breach
or threatened breach of Sections 5 or 6 of this Agreement, and, in any action or
proceeding to enforce the provisions of Sections 5 or 6 hereof, the Employee
waives the claim or defense that the Company has an adequate remedy at law and
will not assert the claim or defense that such a remedy at law exists. The
Company is entitled to injunctive relief to enforce the provisions of such
sections as well as any and all other remedies available to it at law or in
equity without the posting of any bond.

         25. Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original and both of which together shall constitute
one and the same instrument.

                       FIRST AMENDED EMPLOYMENT AGREEMENT


        THIS FIRST AMENDED EMPLOYMENT AGREEMENT is made and entered into as
October 1, 1997, by and between Darrell Chambliss (the "Employee") and Waste
Connections, Inc., a Delaware corporation (the "Company"), and amends and
restates the Employment Agreement entered into by the parties as of October 1,
1997, with reference to the following facts.

        The Company desires to engage the services and employment of the
Employee for the period provided in this Agreement, and the Employee is willing
to accept employment by the Company for such period, on the terms and conditions
set forth below.

        NOW THEREFORE, in consideration of the premises and the mutual covenants
and conditions herein, the Company and the Employee agree as follows:

        1. Employment. The Company agrees to employ the Employee, and the
Employee agrees to accept employment with the Company, for the Term stated in
Section 3 hereof and on the other terms and conditions herein.

        2. Position and Responsibilities. During the Term, the Employee shall
serve as Vice President -- Operations of the Company, reporting directly to the
Company's President, and perform such other duties and responsibilities as the
President or the Board of Directors (the "Board") of the Company may reasonably
assign to the Employee from time to time. The Employee shall be based at the
Company's corporate headquarters in Roseville, California. The Employee shall
devote such time and attention to his duties as are necessary to the proper
discharge of his responsibilities hereunder. The Employee agrees to perform all
duties consistent with (a) policies established from time to time by the Company
and (b) all applicable legal requirements.

        3. Term. The period of the Employee's employment under this Agreement
(the "Term") commenced on October 1, 1997, and shall continue through September
30, 2000, unless terminated earlier as provided herein or extended by the Board.
At the end of the initial Term, this Agreement shall be renewed automatically
for successive Terms of one year, unless either party shall have given the other
notice of termination hereof as provided herein.

        4.     Compensation, Benefits and Reimbursement of Expenses.

               (a) Compensation. The Company shall compensate the Employee
during the Term of this Agreement as follows:

                      (1) Base Salary. The Employee shall be paid a base salary
("Base Salary") of not less than Eighty-Five Thousand Dollars ($85,000) per year
in installments

                                        1

<PAGE>   2
consistent with the Company's usual practices. The Board shall review the
Employee's Base Salary on October 1 of each year or more frequently, at the
times prescribed in salary administration practices applied generally to
management employees of the Company; provided, however, that if an IPO Closing
(as defined below) with respect to the Company's Common Stock occurs on or
before October 1, 1998, the Employee's Base Salary shall be adjusted on October
1, 1998, to One Hundred Thousand Dollars ($100,000) per year, and if an IPO
Closing has not occurred by October 1, 1998, the Employee's Base Salary shall be
adjusted on that date to Ninety-Two Thousand Dollars ($92,000) per year. An "IPO
Closing" means (i) the date the shares of the Company's Common Stock issued in
an initial public offering registered under the Securities Act of 1933, as
amended (an "IPO"), are sold to the underwriter, if the IPO is a fully
underwritten offering, or (ii) the day following the closing of the Company's
IPO, if the IPO is a best efforts offering.

                      (2) Performance Bonus. The Employee shall be entitled to
an annual cash bonus (the "Bonus") based on the Company's attainment of
reasonable financial objectives to be determined annually by the Board. The
maximum annual Bonus will equal fifty percent (50%) of the applicable year's
ending Base Salary and will be payable if the Board determines, in its sole and
exclusive discretion, that that year's financial objectives have been fully met.
Notwithstanding the foregoing, the Employee will be guaranteed a minimum Bonus
of $17,000 for the 15-month period ending December 31, 1998, and the total Bonus
for such period shall not be subject to the maximum percentage limit described
above. Such minimum Bonus shall be paid on February 15, 1998, and any additional
Bonus for such period shall be paid no later than February 20, 1999. The Bonus
with respect to fiscal years beginning after December 31, 1998 shall be paid in
accordance with the Company's bonus plan, as approved by the Board; provided
that in no case shall any portion of the Bonus with respect to any such fiscal
year be paid more than seventy-five (75) days after the end of such fiscal year.

                      (3) Grant of Options. The Company shall grant to the
Employee, for no additional consideration, stock options (the "Options") to
purchase 150,000 shares of the Company's Common Stock under the Company's Stock
Option Plan. The Options shall have a term of 10 years from the date of such
grant. Options to purchase 100,000 of the 150,000 shares of Common Stock shall
be exercisable at a price of $2.80 per share and shall vest and become
exercisable with respect to 33,333 such shares on each of October 1, 1998, and
October 1, 1999, and with respect to 33,334 such shares on October 1, 2000.
Options to purchase 50,000 of the 150,000 shares shall be exercisable at a price
of $10.50 per share and shall vest and become exercisable with respect to 16,667
such shares on October 1, 1998, with respect to 16,667 such shares on October 1,
1999, and with respect to 16,666 such shares on October 1, 2000. The Options
shall be incentive stock options to the extent permitted under the Copmany's
Stock Option Plan, and the terms of the Options shall be described in more
detail in Stock Option Agreements to be entered into between the Employee and
the Company. If at any time while any of the Options are still outstanding the
Company amends its Stock Option Plan to provide for a less favorable vesting
schedule for stock options than that provided herein, any Options then
outstanding shall thereupon be converted to warrants entitling the Employee to

                                        2

<PAGE>   3
purchase the number of shares of Common Stock for which the Employee's then
outstanding Options may be exercised, on the same terms as provided under such
Options.

               If the Employee's employment by the Company is terminated by the
Company without Cause (as defined in Section 7(a)) or by the Employee for Good
Reason (as defined in Section 8(a)) before all of the Options have vested, all
of the outstanding Options shall become vested on such termination. If the
Employee's employment by the Company is terminated by the Company for Cause or
by the Employee without Good Reason before all of the Options have vested, the
Employee shall forfeit any Options that are unvested as of the termination date.

                      (4) Grant of Restricted Stock. On the date of this
Agreement, the Company shall sell to the Employee, for $0.01 per share in cash,
20,000 shares of the Company's Common Stock (the "Restricted Stock"). Such
Restricted Stock shall not be transferable initially by the Employee, but 6,667
shares of Restricted Stock shall become unrestricted and freely transferable
(subject to compliance with all applicable Federal and state securities laws) on
each of October 1, 1998, and October 1, 1999, and the remaining 6,666 shares of
Restricted Stock shall become unrestricted and freely transferable (subject to
compliance with all applicable Federal and state securities laws) on October 1,
2000. If a Change in Control of the Company (as defined in Section 10(b)) occurs
before all of the Employee's Restricted Stock has become unrestricted and freely
transferable under this Section 4(a)(4), all of the Employee's shares of
Restricted Stock shall immediately become unrestricted and freely transferable
on such Change of Control, and all shares of Restricted Stock granted to the
Employee hereunder shall be treated as owned by the Employee without restriction
for the purpose of determining the Employee's percentage ownership of the
Company on such Change of Control. If before all of the Employee's Restricted
Stock has become unrestricted and freely transferable under this Section
4(a)(4), the Employee's employment is terminated by the Company without Cause
(as defined in Section 7(a)) or by the Employee for Good Reason (as defined in
Section 8(a)), all of the Employee's shares of Restricted Stock shall
immediately become unrestricted and freely transferable on such termination. If
the Employee's employment is terminated by the Company for Cause or by the
Employee without Good Reason before all of the Restricted Stock has become
unrestricted and freely transferable, the Company may, within 90 days after such
termination of employment, repurchase from the Employee for $0.01 per share in
cash any shares of Restricted Stock that are subject to restrictions on transfer
under this Section 4(a)(4) as of the termination date. The Employee may in his
sole discretion file an election under Section 83(b) of the Internal Revenue
Code of 1986, as amended (the "Code"), with respect to the Restricted Stock.

               (b) Other Benefits. During the Term, the Company shall provide
the Employee with a cellular telephone and will pay or reimburse the Employee's
monthly service fee and costs of calls attributable to Company business. During
the Term, the Employee shall be entitled to receive all other benefits of
employment generally available to other management employees of the Company and
those benefits for which management employees are or shall become eligible,
including, without limitation and to the extent made available by the Company,
medical, dental, disability and prescription coverage, life insurance and
tax-qualified retirement

                                        3

<PAGE>   4
benefits. The Employee shall be entitled to three (3) weeks of paid vacation
each year of his employment.

               (c) Reimbursement of Other Expenses. The Company agrees to pay or
reimburse the Employee for all reasonable travel and other expenses (including
mileage for business use of employee's personal automobile at the maximum rate
permitted under Internal Revenue Service regulations) incurred by the Employee
in connection with the performance of his duties under this Agreement on
presentation of proper expense statements or vouchers. All such supporting
information shall comply with all applicable Company policies relating to
reimbursement for travel and other expenses.

               (d) Withholding. All compensation payable to the Employee
hereunder is subject to all withholding requirements under applicable law.

        5. Confidentiality. During the Term of his employment, and at all times
thereafter, the Employee shall not, without the prior written consent of the
Company, divulge to any third party or use for his own benefit or the benefit of
any third party or for any purpose other than the exclusive benefit of the
Company, any confidential or proprietary business or technical information
revealed, obtained or developed in the course of his employment with the Company
and which is otherwise the property of the Company or any of its affiliated
corporations, including, but not limited to, trade secrets, customer lists,
formulae and processes of manufacture; provided, however, that nothing herein
contained shall restrict the Employee's ability to make such disclosures during
the course of his employment as may be necessary or appropriate to the effective
and efficient discharge of his duties to the Company.

        6. Property. Both during the Term of his employment and thereafter, the
Employee shall not remove from the Company's offices or premises any Company
documents, records, notebooks, files, correspondence, reports, memoranda and
similar materials or property of any kind unless necessary in accordance with
the duties and responsibilities of his employment. In the event that any such
material or property is removed, it shall be returned to its proper file or
place of safekeeping as promptly as possible. The Employee shall not make,
retain, remove or distribute any copies, or divulge to any third person the
nature or contents of any of the foregoing or of any other oral or written
information to which he may have access, except as disclosure shall be necessary
in the performance of his assigned duties. On the termination of his employment
with the Company, the Employee shall leave with or return to the Company all
originals and copies of the foregoing then in his possession or subject to his
control, whether prepared by the Employee or by others.

        7.     Termination By Company.

               (a) Termination for Cause. The employment of the Employee may be
terminated for Cause at any time by the Board; provided, however, that before
the Company may terminate the Employee's employment for Cause for any reason
that is susceptible to cure,

                                        4

<PAGE>   5
the Company shall first send the Employee written notice of its intention to
terminate this Agreement for Cause, specifying in such notice the reasons for
such Cause and those conditions that, if satisfied by the Employee, would cure
the reasons for such Cause, and the Employee shall have 60 days from receipt of
such written notice to satisfy such conditions. If such conditions are satisfied
within such 60-day period, the Company shall so advise the Employee in writing.
If such conditions are not satisfied within such 60-day period, the Company may
thereafter terminate this Agreement for Cause on written Notice of Termination
(as defined in Section 9(a)) delivered to the Employee describing with
specificity the grounds for termination. Immediately on termination pursuant to
this Section 7(a), the Company shall pay to the Employee in a lump sum his then
current Base Salary under Section 4(a)(1) on a prorated basis to the Date of
Termination (as defined in Section 9(b)). On termination pursuant to this
Section 7(a), the Employee shall forfeit (i) his Bonus under Section 4(a)(2) for
the year in which such termination occurs, and (ii) all outstanding but unvested
Options and other options and rights relating to capital stock of the Company,
and all shares of Restricted Stock that as of the termination date are still
subject to the restrictions on transfer imposed by Section 4(a)(4) shall be
subject to repurchase by the Company as provided in Section 4(a)(4). For
purposes of this Agreement, Cause shall mean:

                      (1) a material breach of any of the terms of this
Agreement that is not immediately corrected following written notice of default
specifying such breach;

                      (2) a breach of any of the provisions of Section 12;

                      (3) repeated intoxication with alcohol or drugs while on
Company premises during its regular business hours to such a degree that, in the
reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

                      (4) conviction of a felony; or

                      (5) misappropriation of property belonging to the Company
and/or any of its affiliates.

               (b) Termination Without Cause. The employment of the Employee may
be terminated without Cause at any time by the Board on delivery to the Employee
of a written Notice of Termination (as defined in Section 9(a)). On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(b), the
Company shall pay to the Employee in a lump sum an amount equal to the sum of
(i) all Base Salary payable under Section 4(a)(1) through the termination date,
(ii) a pro-rated portion of the maximum Bonus available to the Employee under
Section 4(a)(2) for the year in which the termination occurs, and (iii) an
amount equal to the aggregate Total Compensation paid to the Employee by the
Company with respect to the twelve months preceding the termination date. For
purposes of this section 7(b), the Employee's Total Compensation shall equal the
sum of the Base Salary, Bonus, and other benefits and expense reimbursements
described in Section 4(b) paid to the Employee by the Company. In addition,

                                        5

<PAGE>   6
on termination of the Employee under this Section 7(b), all of the Employee's
outstanding but unvested Options and other options and rights relating to
capital stock of the Company shall immediately vest and become exercisable, and
all shares of the Employee's Restricted Stock shall immediately become
unrestricted and freely transferable. The term of any such options and rights
shall be extended to the third anniversary of the Employee's termination. The
Employee acknowledges that extending the term of any Options pursuant to this
Section 7(b), or Section 7(c), 7(d) or 8(a), could cause such Option to lose its
tax-qualified status if it is an incentive stock option under the Code and
agrees that the Company shall have no obligation to compensate the Employee for
any additional taxes he incurs as a result.

               (c) Termination on Disability. If during the Term the Employee
should fail to perform his duties hereunder on account of physical or mental
illness or other incapacity which the Board shall in good faith determine
renders the Employee incapable of performing his duties hereunder, and such
illness or other incapacity shall continue for a period of more than six (6)
consecutive months ("Disability"), the Company shall have the right, on written
Notice of Termination (as defined in Section 9(a)) delivered to the Employee to
terminate the Employee's employment under this Agreement. During the period that
the Employee shall have been incapacitated due to physical or mental illness,
the Employee shall continue to receive the full Base Salary provided for in
Section 4(a)(1) hereof at the rate then in effect until the Date of Termination
(as defined in Section 9(b)) pursuant to this Section 7(c). On the Date of
Termination pursuant to this Section 7(c), the Company shall pay to the Employee
in a lump sum an amount equal to (i) the Base Salary remaining payable to the
Employee under Section 4(a)(1) for the full remaining Term, plus (ii) a
pro-rated portion of the maximum Bonus available to the Employee under Section
4(a)(2) for the year in which the termination occurs. In addition, on such
termination, all of the Employee's outstanding but unvested Options and other
options and rights relating to capital stock of the Company shall immediately
vest and become exercisable, and all shares of the Employee's Restricted Stock
shall immediately become unrestricted and freely transferable. The term of any
such options and rights shall be extended to the third anniversary of the
Employee's termination.

               (d) Termination on Death. If the Employee shall die during the
Term, the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof. In
addition, on termination of the Employee under this Section 7(d), all of the
Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.
The provisions of this Section 7(d) shall not affect the entitlements of the
Employee's heirs, executors, administrators, legatees, beneficiaries or assigns
under any employee benefit plan, fund or program of the Company.

         8. Termination By Employee.

                                        6

<PAGE>   7
               (a) Termination for Good Reason. The Employee may terminate his
employment hereunder for Good Reason (as defined below). On the Date of
Termination pursuant to this Section 8(a), the Employee shall be entitled to
receive, and the Company agrees to pay and deliver, the payments and other
benefits applicable to termination without Cause set forth in Section 7(b)
hereof. In addition, on termination of the Employee under this Section 8(a), all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.

               For purposes of this Agreement, "Good Reason" shall mean:

                      (1) assignment to the Employee of duties inconsistent with
his responsibilities as they existed on the date of this Agreement; a
substantial alteration in the title(s) of the Employee (so long as the existing
corporate structure of the Company is maintained); or a substantial alteration
in the status of the Employee in the Company organization as it existed on the
date of this Agreement;

                      (2) the relocation of the Company's principal executive
office to a location more than fifty (50) miles from its present location;

                      (3) a reduction by the Company in the Employee's Base
Salary without the Employee's prior approval;

                      (4) a failure by the Company to continue in effect,
without substantial change, any benefit plan or arrangement in which the
Employee was participating or the taking of any action by the Company which
would adversely affect the Employee's participation in or materially reduce his
benefits under any benefit plan (unless such changes apply equally to all other
management employees of Company);

                      (5) any material breach by the Company of any provision of
this Agreement without the Employee having committed any material breach of his
obligations hereunder, which breach is not cured within twenty (20) days
following written notice thereof to the Company of such breach; or

                      (6) the failure of the Company to obtain the assumption of
this Agreement by any successor entity.

               (b) Termination Without Good Reason. The Employee may terminate
his employment hereunder without Good Reason on written Notice of Termination
delivered to the Company setting forth the effective date of termination. If the
Employee terminates his employment hereunder without Good Reason, he shall be
entitled to receive, and the Company agrees to pay on the effective date of
termination specified in the Notice of Termination, his

                                        7

<PAGE>   8
current Base Salary under Section 4(a)(1) hereof on a prorated basis to such
date of termination. On termination pursuant to this Section 8(b), the Employee
shall forfeit (i) his Bonus under Section 4(a)(2) for the year in which such
termination occurs and (ii) all outstanding but unvested Options and other
options and rights relating to capital stock of the Company, and all shares of
Restricted Stock that as of the termination date are still subject to the
restrictions on transfer imposed by Section 4(a)(4) shall be subject to
repurchase by the Company as provided in Section 4(a)(4).

        9.     Provisions Applicable to Termination of Employment.

               (a) Notice of Termination. Any purported termination of
Employee's employment by the Company pursuant to Section 7 shall be communicated
by Notice of Termination to the Employee as provided herein, and shall state the
specific termination provisions in this Agreement relied on and set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment ("Notice of Termination"). If the
Employee terminates under Section 8, he shall give the Company a Notice of
Termination.

               (b) Date of Termination. For all purposes, "Date of Termination"
shall mean, for Disability, thirty (30) days after Notice of Termination is
given to the Employee (provided the Employee has not returned to duty on a
full-time basis during such 30-day period), or, if the Employee's employment is
terminated by the Company for any other reason or by the Employee, the date on
which a Notice of Termination is given.

               (c) Benefits on Termination. On termination of this Agreement by
the Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

        10.    Change In Control.

               (a) Payments on Change in Control. Notwithstanding any provision
in this Agreement to the contrary, unless the Employee elects in writing to
waive this provision, a Change in Control (as defined below) of the Company
shall be deemed a termination of the Employee without Cause, and the Employee
shall be entitled to receive and the Company agrees to pay to the Employee in a
lump sum the same amount determined under Section 7(b) that is payable to the
Employee on termination without Cause. In addition, on a Change of Control, all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, the term of any such options and rights shall be extended to the
third anniversary of the Employee's termination, and all shares of the
Employee's Restricted Stock shall immediately become unrestricted and freely
transferable.


                                        8

<PAGE>   9
               After a Change in Control, if any previously outstanding Option
or other option or right (the "Terminated Option") relating to the Company's
capital stock does not remain outstanding, the successor to the Company or its
then Parent (as defined below) shall either:

                      (i) Issue an option, warrant or right, as appropriate (the
"Successor Option"), to purchase common stock of such successor or Parent in an
amount such that on exercise of the Successor Option the Employee would receive
the same number of shares of the successor's/Parent's common stock as the
Employee would have received had the Employee exercised the Terminated Option
immediately prior to the transaction resulting in the Change in Control and
received shares of such successor/Parent in such transaction. The aggregate
exercise price for all of the shares covered by such Successor Option shall
equal the aggregate exercise price of the Terminated Option; or

                      (ii) Pay the Employee a bonus within ten (10) days after
the consummation of the Change in Control in an amount agreed to by the Employee
and the Company. Such amount shall be at least equivalent on an after-tax basis
to the net after-tax gain that the Employee would have realized if he had been
issued a Successor Option under clause (i) above and had immediately exercised
such Successor Option and sold the underlying stock, taking into account the
different tax rates that apply to such bonus and to such gain, and such amount
shall also reflect other differences to the Employee between receiving a bonus
under this clause (ii) and receiving a Successor Option under clause (i) above.

               (b) Definitions. For the purposes of this Agreement, a Change in
Control shall be deemed to have occurred if (i) there shall be consummated (aa)
any reorganization, liquidation or consolidation of the Company, or any merger
or other business combination of the Company with any other corporation, other
than any such merger or other combination that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or if
(ii) any "person" (as defined in Section 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), shall become the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of fifty percent (50%) or more of the Company's outstanding
voting securities (except that for purposes of this Section 10(b), "person"
shall not include any person (or any person that controls, is controlled by or
is under common control with such person) who as of the date of this Agreement
owns ten percent (10%) or more of the total voting power represented by the
outstanding voting securities of the Company, or a trustee or other fiduciary
holding securities under any employee benefit plan of the Company, or a
corporation that is owned directly or indirectly by the stockholders of the
Company in substantially the same percentage as their ownership of the Company)
or if (iii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the entire Board shall cease for any reason
to constitute at least one-half of the

                                        9

<PAGE>   10
membership thereof unless the election, or the nomination for election by the
Company's shareholders, of each new director was approved by a vote of at least
one-half of the directors then still in office who were directors at the
beginning of the period.

               The term "Parent" means a corporation, partnership, trust,
limited liability company or other entity that is the ultimate "beneficial
owner" (as defined above) of fifty percent (50%) or more of the Company's
outstanding voting securities.

        11. Gross Up Payments. If all or any portion of any payment or benefit
that the Employee is entitled to receive from the Company pursuant to this
Agreement (a "Payment") constitutes an "excess parachute payment" within the
meaning of Section 280G of the Code, and as such is subject to the excise tax
imposed by Section 4999 of the Code or to any similar Federal, state or local
tax or assessment (the "Excise Tax"), the Company or its successors or assigns
shall pay to the Employee an additional amount (the "Gross-Up Payment") with
respect to such Payment. The amount of the Gross-Up Payment shall be sufficient
that, after paying (a) any Excise Tax on the Payment, (b) any Federal, state or
local income or employment taxes and Excise Tax on the Gross-Up Payment, and (c)
any interest and penalties imposed in respect of the Excise Tax, the Employee
shall retain an amount equal to the full amount of the Payment. For the purpose
of determining the amount of any Gross-Up Payment, the Employee shall be deemed
to pay Federal income taxes at the highest marginal rate applicable in the
calendar year in which the Gross-Up Payment is made, and state and local income
taxes at the highest marginal rate applicable in the state and locality where
the Employee resides on the date the Gross-Up Payment is made, net of the
maximum reduction in Federal income taxes that could be obtained from deducting
such state and local taxes.

               The Gross-Up Payment with respect to any Payment shall be paid to
the Employee within ten (10) days after the Internal Revenue Service or any
other taxing authority issues a notice stating that an Excise Tax is due with
respect to the Payment, unless the Company undertakes to challenge the taxing
authority on the applicability of such Excise Tax and indemnifies the Employee
for (a) any amounts ultimately determined to be payable, including the Excise
Tax and any related interest and penalties, (b) all expenses (including
attorneys' and experts' fees) reasonably incurred by the Employee in connection
with such challenge, as such expenses are incurred, and (c) all amounts that the
Employee is required to pay to the taxing authorities during the pendency of
such challenge (such amounts to be repaid by the Employee to the Company if they
are ultimately refunded to the Employee by the taxing authority).

        12.    Non-Competition and Non-Solicitation.

               (a) In consideration of the provisions hereof, for the period
commencing on the date hereof and ending on the first anniversary of the
termination of this Agreement by the Company with Cause pursuant to Section 7(a)
or by the Employee without Good Reason pursuant to Section 8(b), the Employee
will not, except as specifically provided below, anywhere in any county in any
state in which the Company is engaged in business as of such termination date,
directly or indirectly, acting individually or as the owner, shareholder,
partner or

                                       10

<PAGE>   11
management employee of any entity, (i) engage in the operation of a solid waste
collection, transporting or disposal business, transfer facility, recycling
facility, materials recovery facility or solid waste landfill; (ii) enter the
employ as a manager 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 management salary, commissions or otherwise from,
any business engaged in such activities in such counties; or (iii) 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 or trustee;
provided, however, that the Employee may own, directly or indirectly, solely as
an investment, securities of any business traded on any national securities
exchange or quoted on any NASDAQ market, provided the Employee is not a
controlling person of, or a member of a group which controls, such business and
further provided that the Employee does not, in the aggregate, directly or
indirectly, own two percent (2%) or more of any class of securities of such
business.

               (b) After termination of this Agreement by the Company with Cause
pursuant to Section 7(a) or by the Employee without Good Reason pursuant to
Section 8(b), the Employee shall not (i) solicit any residential or commercial
customer of the Company to whom the Company provides service pursuant to a
franchise agreement with a public entity in any county in any state in which the
Company is engaged in business as of such termination date, (ii) solicit any
residential or commercial customer of the Company to enter into a solid waste
collection account relationship with a competitor of the Company in any such
county, (iii) solicit any such public entity to enter into a franchise agreement
with any such competitor, (iv) solicit any officer, employee or contractor of
the Company to enter into an employment or contractor agreement with a
competitor of the Company or otherwise interfere in any such relationship, or
(v) solicit on behalf of a competitor of the Company any prospective customer of
the Company that the Employee called on or was involved in soliciting on behalf
of the Company during the Term, in each case until the second anniversary of the
date of such termination, unless otherwise permitted to do so by Section 12(a).

               (c) If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 12 is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specified words or phrases
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

        13. Indemnification. As an employee and agent of the Company, the
Employee shall be fully indemnified by the Company to the fullest extent
permitted by applicable law in connection with his employment hereunder.


                                       11

<PAGE>   12
        14. Survival of Provisions. The obligations of the Company under Section
13 of this Agreement, and of the Employee under Section 12 of this Agreement,
shall survive both the termination of the Employee's employment and this
Agreement.

        15. No Duty to Mitigate; No Offset. The Employee shall not be required
to mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

        16. Assignment; Binding Agreement. The Company may assign this Agreement
to any parent, subsidiary, affiliate or successor of the Company. This Agreement
is not assignable by the Employee and is binding on him and his executors and
other legal representatives. This Agreement shall bind the Company and its
successors and assigns and inure to the benefit of the Employee and his heirs,
executors, administrators, personal representatives, legatees or devisees. The
Company shall assign this Agreement to any entity that acquires its assets or
business.

        17. Notice. Any written notice under this Agreement shall be personally
delivered to the other party or sent by certified or registered mail, return
receipt requested and postage prepaid, to such party at the address set forth in
the records of the Company or to such other address as either party may from
time to time specify by written notice.

        18. Entire Agreement; Amendments. This Agreement contains the entire
agreement of the parties relating to the Employee's employment and supersedes
all oral or written prior discussions, agreements and understandings of every
nature between them. This Agreement may not be changed except by an agreement in
writing signed by the Company and the Employee.

        19. Waiver. The waiver of a breach of any provision of this Agreement
shall not operate or as be construed to be a waiver of any other provision or
subsequent breach of this Agreement.

        20. Governing Law and Jurisdictional Agreement. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of California.

        21. Severability. In case any one or more of the provisions contained in
this Agreement is, for any reason, held invalid in any respect, such invalidity
shall not affect the validity of any other provision of this Agreement, and such
provision shall be deemed modified to the extent necessary to make it
enforceable.

        22. Enforcement. It is agreed that it is impossible to measure fully, in
money, the damage which will accrue to the Company in the event of a breach or
threatened breach of Sections 5, 6, or 12 of this Agreement, and, in any action
or proceeding to enforce the provisions of Sections 5, 6 or 12 hereof, the
Employee waives the claim or defense that the Company has an adequate remedy at
law and will not assert the claim or defense that such a

                                       12

<PAGE>   13
remedy at law exists. The Company is entitled to injunctive relief to enforce
the provisions of such sections as well as any and all other remedies available
to it at law or in equity without the posting of any bond. The Employee agrees
that if the Employee breaches any provision of Section 12, the Company may
recover as partial damages all profits realized by the Employee at any time
prior to such recovery on the exercise of any warrant, option or right to
purchase the Company's Common Stock and the subsequent sale of such stock, and
may also cancel all outstanding such warrants, options and rights.

        23. Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original and both of which together shall constitute
one and the same instrument.

        24. Due Authorization. The execution of this Agreement has been duly
authorized by the Company by all necessary corporate action.

        IN WITNESS WHEREOF, the parties have executed and delivered this First
Amended Employment Agreement as of the day and year set forth above.

                       FIRST AMENDED EMPLOYMENT AGREEMENT



        THIS FIRST AMENDED EMPLOYMENT AGREEMENT is made and entered into as of
October 1, 1997, by and between Michael Foos (the "Employee") and Waste
Connections, Inc., a Delaware corporation (the "Company"), and amends and
restates the Employment Agreement entered into by the parties as of October 1,
1997, with reference to the following facts.

        The Company desires to engage the services and employment of the
Employee for the period provided in this Agreement, and the Employee is willing
to accept employment by the Company for such period, on the terms and conditions
set forth below.

        NOW THEREFORE, in consideration of the premises and the mutual covenants
and conditions herein, the Company and the Employee agree as follows:

        1. Employment. The Company agrees to employ the Employee, and the
Employee agrees to accept employment with the Company, for the Term stated in
Section 3 hereof and on the other terms and conditions herein.

        2. Position and Responsibilities. During the Term, the Employee shall
serve as Vice President and Corporate Controller of the Company, reporting
directly to the Company's Chief Financial Officer, and perform such other duties
and responsibilities as the Chief Financial Officer or the Board of Directors
(the "Board") of the Company may reasonably assign to the Employee from time to
time. The Employee shall be based at the Company's corporate headquarters in
Roseville, California. The Employee shall devote such time and attention to his
duties as are necessary to the proper discharge of his responsibilities
hereunder. The Employee agrees to perform all duties consistent with (a)
policies established from time to time by the Company and (b) all applicable
legal requirements.

        3. Term. The period of the Employee's employment under this Agreement
(the "Term") commenced on October 1, 1997, and shall continue through September
30, 2000, unless terminated earlier as provided herein or extended by the Board.
At the end of the initial Term, this Agreement shall be renewed automatically
for successive Terms of one year, unless either party shall have given the other
notice of termination hereof as provided herein.

        4. Compensation, Benefits and Reimbursement of Expenses.

               (a) Compensation. The Company shall compensate the Employee
during the Term of this Agreement as follows:

                      (1) Base Salary. The Employee shall be paid a base salary
("Base Salary") of not less than Eighty-Five Thousand Dollars ($85,000) per year
in installments

                                        1

<PAGE>   2
consistent with the Company's usual practices. The Board shall review the
Employee's Base Salary on October 1 of each year or more frequently, at the
times prescribed in salary administration practices applied generally to
management employees of the Company; provided, however, that if an IPO Closing
(as defined below) with respect to the Company's Common Stock occurs on or
before October 1, 1998, the Employee's Base Salary shall be adjusted on October
1, 1998, to One Hundred Thousand Dollars ($100,000) per year, and if an IPO
Closing has not occurred by October 1, 1998, the Employee's Base Salary shall be
adjusted on that date to Ninety-Two Thousand Dollars ($92,000) per year. An "IPO
Closing" means (i) the date the shares of the Company's Common Stock issued in
an initial public offering registered under the Securities Act of 1933, as
amended (an "IPO"), are sold to the underwriter, if the IPO is a fully
underwritten offering, or (ii) the day following the closing of the Company's
IPO, if the IPO is a best efforts offering.

                      (2) Performance Bonus. The Employee shall be entitled to
an annual cash bonus (the "Bonus") based on the Company's attainment of
reasonable financial objectives to be determined annually by the Board. The
maximum annual Bonus will equal thirty-five percent (35%) of the applicable
year's ending Base Salary and will be payable if the Board determines, in its
sole and exclusive discretion, that that year's financial objectives have been
fully met. Notwithstanding the foregoing, the Employee will be guaranteed a
minimum Bonus of $32,000 for the 15-month period ending December 31, 1998, and
the total Bonus for such period shall not be subject to the maximum percentage
limit described above. Such Bonus shall be paid in installments, as follows:
$22,000 on February 15, 1998, $10,000 on October 15, 1998, and any additional
Bonus for such period shall be paid no later than February 20, 1999. The Bonus
with respect to fiscal years beginning after December 31, 1998 shall be paid in
accordance with the Company's bonus plan, as approved by the Board; provided
that in no case shall any portion of the Bonus with respect to any such fiscal
year be paid more than seventy-five (75) days after the end of such fiscal year.

                      (3) Grant of Options. The Company shall grant to the
Employee, for no additional consideration, stock options (the "Options") to
purchase 150,000 shares of the Company's Common Stock under the Company's Stock
Option Plan. The Options shall have a term of 10 years from the date of such
grant. Options to purchase 100,000 of the 150,000 shares of Common Stock shall
be exercisable at a price of $2.80 per share and shall vest and become
exercisable with respect to 33,333 such shares on each of October 1, 1998, and
October 1, 1999, and with respect to 33,334 such shares on October 1, 2000.
Options to purchase 50,000 of the 150,000 shares shall be exercisable at a price
of $10.50 per share and shall vest and become exercisable with respect to 16,667
such shares on October 1, 1998, with respect to 16,667 such shares on October 1,
1999, and with respect to 16,666 such shares on October 1, 2000. The Options
shall be incentive stock options to the extent permitted under the Company's
Stock Option Plan, and the terms of the Options shall be described in more
detail in Stock Option Agreements to be entered into between the Employee and
the Company. If at any time while any of the Options are still outstanding the
Company amends its Stock Option Plan to provide for a less favorable vesting
schedule for stock options than that provided herein, any Options then
outstanding shall thereupon be converted to warrants entitling the Employee to

                                        2

<PAGE>   3
purchase the number of shares of Common Stock for which the Employee's then
outstanding Options may be exercised, on the same terms as provided under such
Options.

               If the Employee's employment by the Company is terminated by the
Company without Cause (as defined in Section 7(a)) or by the Employee for Good
Reason (as defined in Section 8(a)) before all of the Options have vested, all
of the outstanding Options shall become vested on such termination. If the
Employee's employment by the Company is terminated by the Company for Cause or
by the Employee without Good Reason before all of the Options have vested, the
Employee shall forfeit any Options that are unvested as of the termination date.

                      (4) Grant of Restricted Stock. On the date of this
Agreement, the Company shall sell to the Employee, for $0.01 per share in cash,
20,000 shares of the Company's Common Stock (the "Restricted Stock"). Such
Restricted Stock shall not be transferable initially by the Employee, but 6,667
shares of Restricted Stock shall become unrestricted and freely transferable
(subject to compliance with all applicable Federal and state securities laws) on
each of October 1, 1998, and October 1, 1999, and the remaining 6,666 shares of
Restricted Stock shall become unrestricted and freely transferable (subject to
compliance with all applicable Federal and state securities laws) on October 1,
2000. If a Change in Control of the Company (as defined in Section 10(b)) occurs
before all of the Employee's Restricted Stock has become unrestricted and freely
transferable under this Section 4(a)(4), all of the Employee's shares of
Restricted Stock shall immediately become unrestricted and freely transferable
on such Change of Control, and all shares of Restricted Stock granted to the
Employee hereunder shall be treated as owned by the Employee without restriction
for the purpose of determining the Employee's percentage ownership of the
Company on such Change of Control. If before all of the Employee's Restricted
Stock has become unrestricted and freely transferable under this Section
4(a)(4), the Employee's employment is terminated by the Company without Cause
(as defined in Section 7(a)) or by the Employee for Good Reason (as defined in
Section 8(a)), all of the Employee's shares of Restricted Stock shall
immediately become unrestricted and freely transferable on such termination. If
the Employee's employment is terminated by the Company for Cause or by the
Employee without Good Reason before all of the Restricted Stock has become
unrestricted and freely transferable, the Company may, within 90 days after such
termination of employment, repurchase from the Employee for $0.01 per share in
cash any shares of Restricted Stock that are subject to restrictions on transfer
under this Section 4(a)(4) as of the termination date. The Employee may in his
sole discretion file an election under Section 83(b) of the Internal Revenue
Code of 1986, as amended (the "Code"), with respect to the Restricted Stock.

                      (b) Other Benefits. During the Term, the Company shall
provide the Employee with a cellular telephone and will pay or reimburse the
Employee's monthly service fee and costs of calls attributable to Company
business. During the Term, the Employee shall be entitled to receive all other
benefits of employment generally available to other management employees of the
Company and those benefits for which management employees are or shall become
eligible, including, without limitation and to the extent made available by the
Company, medical, dental, disability and prescription coverage, life insurance
and tax-qualified retirement

                                        3

<PAGE>   4
benefits. The Employee shall be entitled to three (3) weeks of paid vacation
each year of his employment.

               (c) Reimbursement of Other Expenses. The Company agrees to pay or
reimburse the Employee for all reasonable travel and other expenses (including
mileage for business use of employee's personal automobile at the maximum rate
permitted under Internal Revenue Service regulations) incurred by the Employee
in connection with the performance of his duties under this Agreement on
presentation of proper expense statements or vouchers. All such supporting
information shall comply with all applicable Company policies relating to
reimbursement for travel and other expenses.

               (d) Withholding. All compensation payable to the Employee
hereunder is subject to all withholding requirements under applicable law.

        5. Confidentiality. During the Term of his employment, and at all times
thereafter, the Employee shall not, without the prior written consent of the
Company, divulge to any third party or use for his own benefit or the benefit of
any third party or for any purpose other than the exclusive benefit of the
Company, any confidential or proprietary business or technical information
revealed, obtained or developed in the course of his employment with the Company
and which is otherwise the property of the Company or any of its affiliated
corporations, including, but not limited to, trade secrets, customer lists,
formulae and processes of manufacture; provided, however, that nothing herein
contained shall restrict the Employee's ability to make such disclosures during
the course of his employment as may be necessary or appropriate to the effective
and efficient discharge of his duties to the Company.

        6. Property. Both during the Term of his employment and thereafter, the
Employee shall not remove from the Company's offices or premises any Company
documents, records, notebooks, files, correspondence, reports, memoranda and
similar materials or property of any kind unless necessary in accordance with
the duties and responsibilities of his employment. In the event that any such
material or property is removed, it shall be returned to its proper file or
place of safekeeping as promptly as possible. The Employee shall not make,
retain, remove or distribute any copies, or divulge to any third person the
nature or contents of any of the foregoing or of any other oral or written
information to which he may have access, except as disclosure shall be necessary
in the performance of his assigned duties. On the termination of his employment
with the Company, the Employee shall leave with or return to the Company all
originals and copies of the foregoing then in his possession or subject to his
control, whether prepared by the Employee or by others.

        7. Termination By Company.

               (a) Termination for Cause. The employment of the Employee may be
terminated for Cause at any time by the Board; provided, however, that before
the Company may terminate the Employee's employment for Cause for any reason
that is susceptible to cure, the Company shall first send the Employee written
notice of its intention to terminate this

                                        4

<PAGE>   5
Agreement for Cause, specifying in such notice the reasons for such Cause and
those conditions that, if satisfied by the Employee, would cure the reasons for
such Cause, and the Employee shall have 60 days from receipt of such written
notice to satisfy such conditions. If such conditions are satisfied within such
60-day period, the Company shall so advise the Employee in writing. If such
conditions are not satisfied within such 60-day period, the Company may
thereafter terminate this Agreement for Cause on written Notice of Termination
(as defined in Section 9(a)) delivered to the Employee describing with
specificity the grounds for termination. Immediately on termination pursuant to
this Section 7(a), the Company shall pay to the Employee in a lump sum his then
current Base Salary under Section 4(a)(1) on a prorated basis to the Date of
Termination (as defined in Section 9(b)). On termination pursuant to this
Section 7(a), the Employee shall forfeit (i) his Bonus under Section 4(a)(2) for
the year in which such termination occurs, and (ii) all outstanding but unvested
Options and other options and rights relating to capital stock of the Company,
and all shares of Restricted Stock that as of the termination date are still
subject to the restrictions on transfer imposed by Section 4(a)(4) shall be
subject to repurchase by the Company as provided in Section 4(a)(4). For
purposes of this Agreement, Cause shall mean:

                      (1) a material breach of any of the terms of this
Agreement that is not immediately corrected following written notice of default
specifying such breach;

                      (2) a breach of any of the provisions of Section 12;

                      (3) repeated intoxication with alcohol or drugs while on
Company premises during its regular business hours to such a degree that, in the
reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

                      (4) conviction of a felony; or

                      (5) misappropriation of property belonging to the Company
and/or any of its affiliates.

               (b) Termination Without Cause. The employment of the Employee may
be terminated without Cause at any time by the Board on delivery to the Employee
of a written Notice of Termination (as defined in Section 9(a)). On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(b), the
Company shall pay to the Employee in a lump sum an amount equal to the sum of
(i) all Base Salary payable under Section 4(a)(1) through the termination date,
(ii) a pro-rated portion of the maximum Bonus available to the Employee under
Section 4(a)(2) for the year in which the termination occurs, and (iii) an
amount equal to the aggregate Total Compensation paid to the Employee by the
Company with respect to the twelve months preceding the termination date. For
purposes of this section 7(b), the Employee's Total Compensation shall equal the
sum of the Base Salary, Bonus, and other benefits and expense reimbursements
described in Section 4(b) paid to the Employee by the Company. In addition, on
termination of the Employee under this Section 7(b), all of the Employee's
outstanding but

                                        5

<PAGE>   6
unvested Options and other options and rights relating to capital stock of the
Company shall immediately vest and become exercisable, and all shares of the
Employee's Restricted Stock shall immediately become unrestricted and freely
transferable. The term of any such options and rights shall be extended to the
third anniversary of the Employee's termination. The Employee acknowledges that
extending the term of any Option pursuant to this Section 7(b), or Section 7(c),
7(d) or 8(a), could cause such Option to lose its tax-qualified status if it is
an incentive stock option under the Code and agrees that the Company shall have
no obligation to compensate the Employee for any additional taxes he incurs as a
result.

               (c) Termination on Disability. If during the Term the Employee
should fail to perform his duties hereunder on account of physical or mental
illness or other incapacity which the Board shall in good faith determine
renders the Employee incapable of performing his duties hereunder, and such
illness or other incapacity shall continue for a period of more than six (6)
consecutive months ("Disability"), the Company shall have the right, on written
Notice of Termination (as defined in Section 9(a)) delivered to the Employee to
terminate the Employee's employment under this Agreement. During the period that
the Employee shall have been incapacitated due to physical or mental illness,
the Employee shall continue to receive the full Base Salary provided for in
Section 4(a)(1) hereof at the rate then in effect until the Date of Termination
(as defined in Section 9(b)) pursuant to this Section 7(c). On the Date of
Termination pursuant to this Section 7(c), the Company shall pay to the Employee
in a lump sum an amount equal to (i) the Base Salary remaining payable to the
Employee under Section 4(a)(1) for the full remaining Term, plus (ii) a
pro-rated portion of the maximum Bonus available to the Employee under Section
4(a)(2) for the year in which the termination occurs. In addition, on such
termination, all of the Employee's outstanding but unvested Options and other
options and rights relating to capital stock of the Company shall immediately
vest and become exercisable, and all shares of the Employee's Restricted Stock
shall immediately become unrestricted and freely transferable. The term of any
such options and rights shall be extended to the third anniversary of the
Employee's termination.

               (d) Termination on Death. If the Employee shall die during the
Term, the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof. In
addition, on termination of the Employee under this Section 7(d), all of the
Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.
The provisions of this Section 7(d) shall not affect the entitlements of the
Employee's heirs, executors, administrators, legatees, beneficiaries or assigns
under any employee benefit plan, fund or program of the Company.

        8. Termination By Employee.


                                        6

<PAGE>   7
               (a) Termination for Good Reason. The Employee may terminate his
employment hereunder for Good Reason (as defined below). On the Date of
Termination pursuant to this Section 8(a), the Employee shall be entitled to
receive, and the Company agrees to pay and deliver, the payments and other
benefits applicable to termination without Cause set forth in Section 7(b)
hereof. In addition, on termination of the Employee under this Section 8(a), all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.

               For purposes of this Agreement, "Good Reason" shall mean:

                      (1) assignment to the Employee of duties inconsistent with
his responsibilities as they existed on the date of this Agreement; a
substantial alteration in the title(s) of the Employee (so long as the existing
corporate structure of the Company is maintained); or a substantial alteration
in the status of the Employee in the Company organization as it existed on the
date of this Agreement;

                      (2) the relocation of the Company's principal executive
office to a location more than fifty (50) miles from its present location;

                      (3) a reduction by the Company in the Employee's Base
Salary without the Employee's prior approval;

                      (4) a failure by the Company to continue in effect,
without substantial change, any benefit plan or arrangement in which the
Employee was participating or the taking of any action by the Company which
would adversely affect the Employee's participation in or materially reduce his
benefits under any benefit plan (unless such changes apply equally to all other
management employees of Company);

                      (5) any material breach by the Company of any provision of
this Agreement without the Employee having committed any material breach of his
obligations hereunder, which breach is not cured within twenty (20) days
following written notice thereof to the Company of such breach; or

                      (6) the failure of the Company to obtain the assumption of
this Agreement by any successor entity.

               (b) Termination Without Good Reason. The Employee may terminate
his employment hereunder without Good Reason on written Notice of Termination
delivered to the Company setting forth the effective date of termination. If the
Employee terminates his employment hereunder without Good Reason, he shall be
entitled to receive, and the Company agrees to pay on the effective date of
termination specified in the Notice of Termination, his

                                        7

<PAGE>   8
current Base Salary under Section 4(a)(1) hereof on a prorated basis to such
date of termination. On termination pursuant to this Section 8(b), the Employee
shall forfeit (i) his Bonus under Section 4(a)(2) for the year in which such
termination occurs, and (ii) all outstanding but unvested Options and other
options and rights relating to capital stock of the Company, and all shares of
Restricted Stock that as of the termination date are still subject to the
restrictions on transfer imposed by Section 4(a)(4) shall be subject to
repurchase by the Company as provided in Section 4(a)(4).

        9. Provisions Applicable to Termination of Employment.

               (a) Notice of Termination. Any purported termination of
Employee's employment by the Company pursuant to Section 7 shall be communicated
by Notice of Termination to the Employee as provided herein, and shall state the
specific termination provisions in this Agreement relied on and set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment ("Notice of Termination"). If the
Employee terminates under Section 8, he shall give the Company a Notice of
Termination.

               (b) Date of Termination. For all purposes, "Date of Termination"
shall mean, for Disability, thirty (30) days after Notice of Termination is
given to the Employee (provided the Employee has not returned to duty on a
full-time basis during such 30-day period), or, if the Employee's employment is
terminated by the Company for any other reason or by the Employee, the date on
which a Notice of Termination is given.

               (c) Benefits on Termination. On termination of this Agreement by
the Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

        10. Change In Control.

               (a) Payments on Change in Control. Notwithstanding any provision
in this Agreement to the contrary, unless the Employee elects in writing to
waive this provision, a Change in Control (as defined below) of the Company
shall be deemed a termination of the Employee without Cause, and the Employee
shall be entitled to receive and the Company agrees to pay to the Employee in a
lump sum the same amount determined under Section 7(b) that is payable to the
Employee on termination without Cause. In addition, on a Change of Control, all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, the term of any such options and rights shall be extended to the
third anniversary of the Employee's termination, and all shares of the
Employee's Restricted Stock shall immediately become unrestricted and freely
transferable.


                                        8

<PAGE>   9
               After a Change in Control, if any previously outstanding Option
or other option or right (the "Terminated Option") relating to the Company's
capital stock does not remain outstanding, the successor to the Company or its
then Parent (as defined below) shall either:

                      (i) Issue an option, warrant or right, as appropriate (the
"Successor Option"), to purchase common stock of such successor or Parent in an
amount such that on exercise of the Successor Option the Employee would receive
the same number of shares of the successor's/Parent's common stock as the
Employee would have received had the Employee exercised the Terminated Option
immediately prior to the transaction resulting in the Change in Control and
received shares of such successor/Parent in such transaction. The aggregate
exercise price for all of the shares covered by such Successor Option shall
equal the aggregate exercise price of the Terminated Option; or

                      (ii) Pay the Employee a bonus within ten (10) days after
the consummation of the Change in Control in an amount agreed to by the Employee
and the Company. Such amount shall be at least equivalent on an after-tax basis
to the net after-tax gain that the Employee would have realized if he had been
issued a Successor Option under clause (i) above and had immediately exercised
such Successor Option and sold the underlying stock, taking into account the
different tax rates that apply to such bonus and to such gain, and such amount
shall also reflect other differences to the Employee between receiving a bonus
under this clause (ii) and receiving a Successor Option under clause (i) above.

               (b) Definitions. For the purposes of this Agreement, a Change in
Control shall be deemed to have occurred if (i) there shall be consummated (aa)
any reorganization, liquidation or consolidation of the Company, or any merger
or other business combination of the Company with any other corporation, other
than any such merger or other combination that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or if
(ii) any "person" (as defined in Section 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), shall become the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of fifty percent (50%) or more of the Company's outstanding
voting securities (except that for purposes of this Section 10(b), "person"
shall not include any person (or any person that controls, is controlled by or
is under common control with such person) who as of the date of this Agreement
owns ten percent (10%) or more of the total voting power represented by the
outstanding voting securities of the Company, or a trustee or other fiduciary
holding securities under any employee benefit plan of the Company, or a
corporation that is owned directly or indirectly by the stockholders of the
Company in substantially the same percentage as their ownership of the Company)
or if (iii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the entire Board shall cease for any reason
to constitute at least one-half of the

                                        9

<PAGE>   10
membership thereof unless the election, or the nomination for election by the
Company's shareholders, of each new director was approved by a vote of at least
one-half of the directors then still in office who were directors at the
beginning of the period.

               The term "Parent" means a corporation, partnership, trust,
limited liability company or other entity that is the ultimate "beneficial
owner" (as defined above) of fifty percent (50%) or more of the Company's
outstanding voting securities.

        11. Gross Up Payments. If all or any portion of any payment or benefit
that the Employee is entitled to receive from the Company pursuant to this
Agreement (a "Payment") constitutes an "excess parachute payment" within the
meaning of Section 280G of the Code, and as such is subject to the excise tax
imposed by Section 4999 of the Code or to any similar Federal, state or local
tax or assessment (the "Excise Tax"), the Company or its successors or assigns
shall pay to the Employee an additional amount (the "Gross-Up Payment") with
respect to such Payment. The amount of the Gross-Up Payment shall be sufficient
that, after paying (a) any Excise Tax on the Payment, (b) any Federal, state or
local income or employment taxes and Excise Tax on the Gross-Up Payment, and (c)
any interest and penalties imposed in respect of the Excise Tax, the Employee
shall retain an amount equal to the full amount of the Payment. For the purpose
of determining the amount of any Gross-Up Payment, the Employee shall be deemed
to pay Federal income taxes at the highest marginal rate applicable in the
calendar year in which the Gross-Up Payment is made, and state and local income
taxes at the highest marginal rate applicable in the state and locality where
the Employee resides on the date the Gross-Up Payment is made, net of the
maximum reduction in Federal income taxes that could be obtained from deducting
such state and local taxes.

               The Gross-Up Payment with respect to any Payment shall be paid to
the Employee within ten (10) days after the Internal Revenue Service or any
other taxing authority issues a notice stating that an Excise Tax is due with
respect to the Payment, unless the Company undertakes to challenge the taxing
authority on the applicability of such Excise Tax and indemnifies the Employee
for (a) any amounts ultimately determined to be payable, including the Excise
Tax and any related interest and penalties, (b) all expenses (including
attorneys' and experts' fees) reasonably incurred by the Employee in connection
with such challenge, as such expenses are incurred, and (c) all amounts that the
Employee is required to pay to the taxing authorities during the pendency of
such challenge (such amounts to be repaid by the Employee to the Company if they
are ultimately refunded to the Employee by the taxing authority).

        12. Non-Competition and Non-Solicitation.

               (a) In consideration of the provisions hereof, for the period
commencing on the date hereof and ending on the first anniversary of the
termination of this Agreement by the Company with Cause pursuant to Section 7(a)
or by the Employee without Good Reason pursuant to Section 8(b), the Employee
will not, except as specifically provided below, anywhere in any county in any
state in which the Company is engaged in business as of such termination date,
directly or indirectly, acting individually or as the owner, shareholder,
partner or

                                       10

<PAGE>   11
management employee of any entity, (i) engage in the operation of a solid waste

facility, materials recovery facility or solid waste landfill; (ii) enter the
employ as a manager of, or render any personal services to or for the benefit
of, or assist in or facilitate the solicitation of customers for, or receive

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 or trustee;
provided, however, that the Employee may own, directly or indirectly, solely as
an investment, securities of any business traded on any national securities
exchange or quoted on any NASDAQ market, provided the Employee is not a
controlling person of, or a member of a group which controls, such business and
further provided that the Employee does not, in the aggregate, directly or
indirectly, own two percent (2%) or more of any class of securities of such
business.

               (b) After termination of this Agreement by the Company with Cause
pursuant to Section 7(a) or by the Employee without Good Reason pursuant to
Section 8(b), the Employee shall not (i) solicit any residential or commercial
customer of the Company to whom the Company provides service pursuant to a
franchise agreement with a public entity in any county in any state in which the
Company is engaged in business as of such termination date, (ii) solicit any
residential or commercial customer of the Company to enter into a solid waste
collection account relationship with a competitor of the Company in any such
county, (iii) solicit any such public entity to enter into a franchise agreement
with any such competitor, (iv) solicit any officer, employee or contractor of
the Company to enter into an employment or contractor agreement with a
competitor of the Company or otherwise interfere in any such relationship, or
(v) solicit on behalf of a competitor of the Company any prospective customer of
the Company that the Employee called on or was involved in soliciting on behalf
of the Company during the Term, in each case until the second anniversary of the
date of such termination, unless otherwise permitted to do so by Section 12(a).

               (c) If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 12 is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specified words or phrases
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

        13. Indemnification. As an employee and agent of the Company, the
Employee shall be fully indemnified by the Company to the fullest extent
permitted by applicable law in connection with his employment hereunder.


                                       11

<PAGE>   12
        14. Survival of Provisions. The obligations of the Company under Section
13 of this Agreement, and of the Employee under Section 12 of this Agreement,
shall survive both the termination of the Employee's employment and this
Agreement.

        15. No Duty to Mitigate; No Offset. The Employee shall not be required
to mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

        16. Assignment; Binding Agreement. The Company may assign this Agreement
to any parent, subsidiary, affiliate or successor of the Company. This Agreement
is not assignable by the Employee and is binding on him and his executors and
other legal representatives. This Agreement shall bind the Company and its
successors and assigns and inure to the benefit of the Employee and his heirs,
executors, administrators, personal representatives, legatees or devisees. The
Company shall assign this Agreement to any entity that acquires its assets or
business.

        17. Notice. Any written notice under this Agreement shall be personally
delivered to the other party or sent by certified or registered mail, return

the records of the Company or to such other address as either party may from
time to time specify by written notice.

        18. Entire Agreement; Amendments. This Agreement contains the entire

all oral or written prior discussions, agreements and understandings of every
nature between them. This Agreement may not be changed except by an agreement in
writing signed by the Company and the Employee.

        19. Waiver. The waiver of a breach of any provision of this Agreement
shall not operate or as be construed to be a waiver of any other provision or
subsequent breach of this Agreement.

governed by and construed and enforced in accordance with the laws of the State
of California.

        21. Severability. In case any one or more of the provisions contained in
this Agreement is, for any reason, held invalid in any respect, such invalidity
shall not affect the validity of any other provision of this Agreement, and such
provision shall be deemed modified to the extent necessary to make it
enforceable.

        22. Enforcement. It is agreed that it is impossible to measure fully, in
money, the damage which will accrue to the Company in the event of a breach or
threatened breach of Sections 5, 6, or 12 of this Agreement, and, in any action
or proceeding to enforce the provisions of Sections 5, 6 or 12 hereof, the
Employee waives the claim or defense that the Company has an adequate remedy at
law and will not assert the claim or defense that such a

                                       12

<PAGE>   13
remedy at law exists. The Company is entitled to injunctive relief to enforce
the provisions of such sections as well as any and all other remedies available
to it at law or in equity without the posting of any bond. The Employee agrees
that if the Employee breaches any provision of Section 12, the Company may
recover as partial damages all profits realized by the Employee at any time
prior to such recovery on the exercise of any warrant, option or right to
purchase the Company's Common Stock and the subsequent sale of such stock, and
may also cancel all outstanding such warrants, options and rights.

        23. Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original and both of which together shall constitute
one and the same instrument.

        24. Due Authorization. The execution of this Agreement has been duly
authorized by the Company by all necessary corporate action.

        IN WITNESS WHEREOF, the parties have executed and delivered this First
Amended Employment Agreement as of the day and year set forth above.

                       FIRST AMENDED EMPLOYMENT AGREEMENT


      THIS FIRST AMENDED EMPLOYMENT AGREEMENT is made and entered into as of
October 1, 1997, by and between Eric Moser (the "Employee") and Waste
Connections, Inc., a Delaware corporation (the "Company"), and amends and
restates the Employment Agreement entered into by the parties as of October 1,
1997, with reference to the following facts.

      The Company desires to engage the services and employment of the Employee
for the period provided in this Agreement, and the Employee is willing to accept
employment by the Company for such period, on the terms and conditions set forth
below.

      NOW THEREFORE, in consideration of the premises and the mutual covenants
and conditions herein, the Company and the Employee agree as follows:

      1.    Employment. The Company agrees to employ the Employee, and the
Employee agrees to accept employment with the Company, for the Term stated in
Section 3 hereof and on the other terms and conditions herein.

      2.    Position and Responsibilities. During the Term, the Employee shall
serve as the Company's Divisional Controller for Washington and Idaho, reporting
directly to the Company's Corporate Controller, and perform such other duties
and responsibilities as the Corporate Controller or the Board of Directors (the
"Board") of the Company may reasonably assign to the Employee from time to time.
The Employee shall be based in Vancouver, Washington. The Employee shall devote
such time and attention to his duties as are necessary to the proper discharge
of his responsibilities hereunder. The Employee agrees to perform all duties
consistent with (a) policies established from time to time by the Company and
(b) all applicable legal requirements.

      3.    Term. The period of the Employee's employment under this Agreement
(the "Term") commenced on October 1, 1997, and shall continue through September
30, 2000, unless terminated earlier as provided herein or extended by the Board.
At the end of the initial Term, this Agreement shall be renewed automatically
for successive Terms of one year, unless either party shall have given the other
notice of termination hereof as provided herein.

      4.    Compensation, Benefits and Reimbursement of Expenses.

            (a)   Compensation. The Company shall compensate the Employee during
the Term of this Agreement as follows:

                  (1)   Base Salary. The Employee shall be paid a base salary
("Base Salary") of not less than Sixty Thousand Dollars ($60,000) per year in
installments consistent with the Company's usual practices. The Board shall
review the Employee's Base Salary on


                                       1
<PAGE>   2
October 1 of each year or more frequently, at the times prescribed in salary
administration practices applied generally to management employees of the
Company; provided, however, that if an IPO Closing (as defined below) with
respect to the Company's Common Stock occurs on or before October 1, 1998, the
Employee shall be offered the position of Assistant Corporate Controller
beginning October 1, 1998, with a Base Salary of Eighty Thousand Dollars
($80,000) per year, provided that the Employee relocates to the Sacramento,
California area by November 1, 1998. If the Employee is offered such position
and rejects it, he and the Company shall renegotiate his Base Salary as of
October 1, 1998. If an IPO Closing does not occur by October 1, 1998, the
Employee's Base Salary shall be adjusted on that date to Seventy Thousand
Dollars ($70,000) per year. An "IPO Closing" means (i) the date the shares of
the Company's Common Stock issued in an initial public offering registered under
the Securities Act of 1933, as amended (an "IPO"), are sold to the underwriter,
if the IPO is a fully underwritten offering, or (ii) the day following the
closing of the Company's IPO, if the IPO is a best efforts offering.

                  (2)   Performance Bonus. The Employee shall be entitled to an
annual cash bonus (the "Bonus") based on the Company's attainment of reasonable
financial objectives to be determined annually by the Board. The maximum annual
Bonus will equal twenty percent (20%) of the applicable year's ending Base
Salary and will be payable if the Board determines, in its sole and exclusive
discretion, that that year's financial objectives have been fully met.
Notwithstanding the foregoing, the Employee will be guaranteed a minimum Bonus
of $5,000 for the 15-month period ending December 31, 1998, and the total Bonus
for such period shall not be subject to the maximum percentage limit described
above. Such minimum Bonus shall be paid on February 15, 1998, and any additional
Bonus for such period shall be paid no later than February 20, 1999. The Bonus
with respect to fiscal years beginning after December 31, 1998 shall be paid in
accordance with the Company's bonus plan, as approved by the Board; provided
that in no case shall any portion of the Bonus with respect to any such fiscal
year be paid more than seventy-five (75) days after the end of such fiscal year.

                  (3)   Grant of Options. On the date of this Agreement, the
Company shall grant to the Employee, for no additional consideration, stock
options (the "Options") to purchase 85,000 shares of the Company's Common Stock
under the Company's Stock Option Plan. The Options shall have a term of 10 years
from the date of such grant. Options to purchase 50,000 of the 85,000 shares of
Common Stock shall be exercisable at a price of $2.80 per share and shall vest
and become exercisable with respect to 25,000 such shares on October 1, 1998,
and with respect to 25,000 such shares on October 1, 1999. Options to purchase
35,000 of the 85,000 shares shall be exercisable at a price of $10.50 per share
and shall vest and become exercisable with respect to 11,667 such shares on
October 1, 1998, with respect to 11,667 such shares on October 1, 1999, and with
respect to 11,666 such shares on October 1, 2000. The Options shall be incentive
stock options to the extent permitted under the Company's Stock Option Plan, and
the terms of the Options shall be described in more detail in Stock Option
Agreements to be entered into between the Employee and the Company. If at any
time while any of the Options are still outstanding the Company amends its Stock
Option Plan to provide for a less favorable vesting schedule for stock options
than that provided herein, any Options then outstanding shall thereupon be
converted to warrants entitling the Employee to


                                       2
<PAGE>   3
purchase the number of shares of Common Stock for which the Employee's then
outstanding Options may be exercised, on the same terms as provided under such
Options.

            If the Employee's employment by the Company is terminated by the
Company without Cause (as defined in Section 7(a)) or by the Employee for Good
Reason (as defined in Section 8(a)) before all of the Options have vested, all
of the outstanding Options shall become vested on such termination. If the
Employee's employment by the Company is terminated by the Company for Cause or
by the Employee without Good Reason before all of the Options have vested, the
Employee shall forfeit any Options that are unvested as of the termination date.

                  (4)   Grant of Restricted Stock. On the date of this
Agreement, the Company shall sell to the Employee, for $0.01 per share in cash,
10,000 shares of the Company's Common Stock (the "Restricted Stock"). Such
Restricted Stock shall not be transferable initially by the Employee, but 3,333
shares of Restricted Stock shall become unrestricted and freely transferable
(subject to compliance with all applicable Federal and state securities laws) on
each of October 1, 1998, and October 1, 1999, and the remaining 3,334 shares of
Restricted Stock shall become unrestricted and freely transferable (subject to
compliance with all applicable Federal and state securities laws) on October 1,
2000. If a Change in Control of the Company (as defined in Section 10(b)) occurs
before all of the Employee's Restricted Stock has become unrestricted and freely
transferable under this Section 4(a)(4), all of the Employee's shares of
Restricted Stock shall immediately become unrestricted and freely transferable
on such Change of Control, and all shares of Restricted Stock granted to the
Employee hereunder shall be treated as owned by the Employee without restriction
for the purpose of determining the Employee's percentage ownership of the
Company on such Change of Control. If before all of the Employee's Restricted
Stock has become unrestricted and freely transferable under this Section
4(a)(4), the Employee's employment is terminated by the Company without Cause
(as defined in Section 7(a)) or by the Employee for Good Reason (as defined in
Section 8(a)), all of the Employee's shares of Restricted Stock shall
immediately become unrestricted and freely transferable on such termination. If
the Employee's employment is terminated by the Company for Cause or by the
Employee without Good Reason before all of the Restricted Stock has become
unrestricted and freely transferable, the Company may, within 90 days after such
termination of employment, repurchase from the Employee for $0.01 per share in
cash any shares of Restricted Stock that are subject to restrictions on transfer
under this Section 4(a)(4) as of the termination date. The Employee may in his
sole discretion file an election under Section 83(b) of the Internal Revenue
Code of 1986, as amended (the "Code"), with respect to the Restricted Stock.

            (b)   Other Benefits. During the Term, the Company shall provide the
Employee with a cellular telephone and will pay or reimburse the Employee's
monthly service fee and costs of calls attributable to Company business. During
the Term, the Employee shall be entitled to receive all other benefits of
employment generally available to other management employees of the Company and
those benefits for which management employees are or shall become eligible,
including, without limitation and to the extent made available by the Company,
medical, dental, disability and prescription coverage, life insurance and
tax-qualified retirement


                                       3
<PAGE>   4
benefits. The Employee shall be entitled to three (3) weeks of paid vacation
each year of his employment.

            (c)   Reimbursement of Other Expenses. The Company agrees to pay or
reimburse the Employee for all reasonable travel and other expenses (including
mileage for business use of employee's personal automobile at the maximum rate
permitted under Internal Revenue Service regulations) incurred by the Employee
in connection with the performance of his duties under this Agreement on
presentation of proper expense statements or vouchers. All such supporting
information shall comply with all applicable Company policies relating to
reimbursement for travel and other expenses.

            (d)   Withholding. All compensation payable to the Employee
hereunder is subject to all withholding requirements under applicable law.

      5.    Confidentiality. During the Term of his employment, and at all times
thereafter, the Employee shall not, without the prior written consent of the
Company, divulge to any third party or use for his own benefit or the benefit of
any third party or for any purpose other than the exclusive benefit of the
Company, any confidential or proprietary business or technical information
revealed, obtained or developed in the course of his employment with the Company
and which is otherwise the property of the Company or any of its affiliated
corporations, including, but not limited to, trade secrets, customer lists,
formulae and processes of manufacture; provided, however, that nothing herein
contained shall restrict the Employee's ability to make such disclosures during
the course of his employment as may be necessary or appropriate to the effective
and efficient discharge of his duties to the Company.

      6.    Property. Both during the Term of his employment and thereafter, the
Employee shall not remove from the Company's offices or premises any Company
documents, records, notebooks, files, correspondence, reports, memoranda and
similar materials or property of any kind unless necessary in accordance with
the duties and responsibilities of his employment. In the event that any such
material or property is removed, it shall be returned to its proper file or
place of safekeeping as promptly as possible. The Employee shall not make,
retain, remove or distribute any copies, or divulge to any third person the
nature or contents of any of the foregoing or of any other oral or written
information to which he may have access, except as disclosure shall be necessary
in the performance of his assigned duties. On the termination of his employment
with the Company, the Employee shall leave with or return to the Company all
originals and copies of the foregoing then in his possession or subject to his
control, whether prepared by the Employee or by others.

      7.    Termination By Company.

            (a)   Termination for Cause. The employment of the Employee may be
terminated for Cause at any time by the Board; provided, however, that before
the Company may terminate the Employee's employment for Cause for any reason
that is susceptible to cure, the Company shall first send the Employee written
notice of its intention to terminate this


                                       4
<PAGE>   5
Agreement for Cause, specifying in such notice the reasons for such Cause and
those conditions that, if satisfied by the Employee, would cure the reasons for
such Cause, and the Employee shall have 60 days from receipt of such written
notice to satisfy such conditions. If such conditions are satisfied within such
60-day period, the Company shall so advise the Employee in writing. If such
conditions are not satisfied within such 60-day period, the Company may
thereafter terminate this Agreement for Cause on written Notice of Termination
(as defined in Section 9(a)) delivered to the Employee describing with
specificity the grounds for termination. Immediately on termination pursuant to
this Section 7(a), the Company shall pay to the Employee in a lump sum his then
current Base Salary under Section 4(a)(1) on a prorated basis to the Date of
Termination (as defined in Section 9(b)). On termination pursuant to this
Section 7(a), the Employee shall forfeit (i) his Bonus under Section 4(a)(2) for
the year in which such termination occurs, and (ii) all outstanding but unvested
Options and other options and rights relating to capital stock of the Company,
and all shares of Restricted Stock that as of the termination date are still
subject to the restrictions on transfer imposed by Section 4(a)(4) shall be
subject to repurchase by the Company as provided in Section 4(a)(4). For
purposes of this Agreement, Cause shall mean:

                  (1)   a material breach of any of the terms of this Agreement
that is not immediately corrected following written notice of default specifying
such breach;

                  (2)   a breach of any of the provisions of Section 12;

                  (3)   repeated intoxication with alcohol or drugs while on
Company premises during its regular business hours to such a degree that, in the
reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

                  (4)   conviction of a felony; or

                  (5)   misappropriation of property belonging to the Company
and/or any of its affiliates.

            (b)   Termination Without Cause. The employment of the Employee may
be terminated without Cause at any time by the Board on delivery to the Employee
of a written Notice of Termination (as defined in Section 9(a)). On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(b), the
Company shall pay to the Employee in a lump sum an amount equal to the sum of
(i) all Base Salary payable under Section 4(a)(1) through the termination date,
(ii) a pro-rated portion of the maximum Bonus available to the Employee under
Section 4(a)(2) for the year in which the termination occurs, and (iii) an
amount equal to the aggregate Total Compensation paid to the Employee by the
Company with respect to the twelve months preceding the termination date. For
purposes of this section 7(b), the Employee's Total Compensation shall equal the
sum of the Base Salary, Bonus, and other benefits and expense reimbursements
described in Section 4(b) paid to the Employee by the Company. In addition, on
termination of the Employee under this Section 7(b), all of the Employee's
outstanding but


                                       5
<PAGE>   6
unvested Options and other options and rights relating to capital stock of the
Company shall immediately vest and become exercisable, and all shares of the
Employee's Restricted Stock shall immediately become unrestricted and freely
transferable. The term of any such options and rights shall be extended to the
third anniversary of the Employee's termination. The Employee acknowledges that
extending the term of any Option pursuant to this Section 7(b), or Section 7(c),
7(d) or 8(a), could cause such Option to lose its tax-qualified status if such
Option is an incentive stock option under the Code and agrees that the Company
shall have no obligation to compensate the Employee for any additional taxes he
incurs as a result.

            (c)   Termination on Disability. If during the Term the Employee
should fail to perform his duties hereunder on account of physical or mental
illness or other incapacity which the Board shall in good faith determine
renders the Employee incapable of performing his duties hereunder, and such
illness or other incapacity shall continue for a period of more than six (6)
consecutive months ("Disability"), the Company shall have the right, on written
Notice of Termination (as defined in Section 9(a)) delivered to the Employee to
terminate the Employee's employment under this Agreement. During the period that
the Employee shall have been incapacitated due to physical or mental illness,
the Employee shall continue to receive the full Base Salary provided for in
Section 4(a)(1) hereof at the rate then in effect until the Date of Termination
(as defined in Section 9(b)) pursuant to this Section 7(c). On the Date of
Termination pursuant to this Section 7(c), the Company shall pay to the Employee
in a lump sum an amount equal to (i) the Base Salary remaining payable to the
Employee under Section 4(a)(1) for the full remaining Term, plus (ii) a
pro-rated portion of the maximum Bonus available to the Employee under Section
4(a)(2) for the year in which the termination occurs. In addition, on such
termination, all of the Employee's outstanding but unvested Options and other
options and rights relating to capital stock of the Company shall immediately
vest and become exercisable, and all shares of the Employee's Restricted Stock
shall immediately become unrestricted and freely transferable. The term of any
such options and rights shall be extended to the third anniversary of the
Employee's termination.

            (d)   Termination on Death. If the Employee shall die during the
Term, the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof. In
addition, on termination of the Employee under this Section 7(d), all of the
Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.
The provisions of this Section 7(d) shall not affect the entitlements of the
Employee's heirs, executors, administrators, legatees, beneficiaries or assigns
under any employee benefit plan, fund or program of the Company.

      8.    Termination By Employee.


                                       6
<PAGE>   7
            (a)   Termination for Good Reason. The Employee may terminate his
employment hereunder for Good Reason (as defined below). On the Date of
Termination pursuant to this Section 8(a), the Employee shall be entitled to
receive, and the Company agrees to pay and deliver, the payments and other
benefits applicable to termination without Cause set forth in Section 7(b)
hereof. In addition, on termination of the Employee under this Section 8(a), all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, and all shares of the Employee's Restricted Stock shall immediately
become unrestricted and freely transferable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.

            For purposes of this Agreement, "Good Reason" shall mean:

                  (1)   assignment to the Employee of duties inconsistent with
his responsibilities as they existed on the date of this Agreement; a
substantial alteration in the title(s) of the Employee (so long as the existing
corporate structure of the Company is maintained); or a substantial alteration
in the status of the Employee in the Company organization as it existed on the
date of this Agreement;

                  (2)   the relocation of the Employee to a location more than
fifty (50) miles from Vancouver;

                  (3)   a reduction by the Company in the Employee's Base Salary
without the Employee's prior approval;

                  (4)   a failure by the Company to continue in effect, without
substantial change, any benefit plan or arrangement in which the Employee was
participating or the taking of any action by the Company which would adversely
affect the Employee's participation in or materially reduce his benefits under
any benefit plan (unless such changes apply equally to all other management
employees of Company);

                  (5)   any material breach by the Company of any provision of
this Agreement without the Employee having committed any material breach of his
obligations hereunder, which breach is not cured within twenty (20) days
following written notice thereof to the Company of such breach; or

                  (6)   the failure of the Company to obtain the assumption of
this Agreement by any successor entity.

            (b)   Termination Without Good Reason. The Employee may terminate
his employment hereunder without Good Reason on written Notice of Termination
delivered to the Company setting forth the effective date of termination. If the
Employee terminates his employment hereunder without Good Reason, he shall be
entitled to receive, and the Company agrees to pay on the effective date of
termination specified in the Notice of Termination, his


                                       7
<PAGE>   8
current Base Salary under Section 4(a)(1) hereof on a prorated basis to such
date of termination. On termination pursuant to this Section 8(b), the Employee
shall forfeit (i) his Bonus under Section 4(a)(2) for the year in which such
termination occurs, and (ii) all outstanding but unvested Options and other
options and rights relating to capital stock of the Company, and all shares of
Restricted Stock that as of the termination date are still subject to the
restrictions on transfer imposed by Section 4(a)(4) shall be subject to
repurchase by the Company as provided in Section 4(a)(4).

      9.    Provisions Applicable to Termination of Employment.

            (a)   Notice of Termination. Any purported termination of Employee's
employment by the Company pursuant to Section 7 shall be communicated by Notice
of Termination to the Employee as provided herein, and shall state the specific
termination provisions in this Agreement relied on and set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Employee's employment ("Notice of Termination"). If the Employee terminates
under Section 8, he shall give the Company a Notice of Termination.

            (b)   Date of Termination. For all purposes, "Date of Termination"
shall mean, for Disability, thirty (30) days after Notice of Termination is
given to the Employee (provided the Employee has not returned to duty on a
full-time basis during such 30-day period), or, if the Employee's employment is
terminated by the Company for any other reason or by the Employee, the date on
which a Notice of Termination is given.

            (c)   Benefits on Termination. On termination of this Agreement by
the Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

      10.   Change In Control.

            (a)   Payments on Change in Control. Notwithstanding any provision
in this Agreement to the contrary, unless the Employee elects in writing to
waive this provision, a Change in Control (as defined below) of the Company
shall be deemed a termination of the Employee without Cause, and the Employee
shall be entitled to receive and the Company agrees to pay to the Employee in a
lump sum the same amount determined under Section 7(b) that is payable to the
Employee on termination without Cause. In addition, on a Change of Control, all
of the Employee's outstanding but unvested Options and other options and rights
relating to capital stock of the Company shall immediately vest and become
exercisable, the term of any such options and rights shall be extended to the
third anniversary of the Employee's termination, and all shares of the
Employee's Restricted Stock shall immediately become unrestricted and freely
transferable.


                                       8
<PAGE>   9
            After a Change in Control, if any previously outstanding Option or
other option or right (the "Terminated Option") relating to the Company's
capital stock does not remain outstanding, the successor to the Company or its
then Parent (as defined below) shall either:

                  (i)   Issue an option, warrant or right, as appropriate (the
"Successor Option"), to purchase common stock of such successor or Parent in an
amount such that on exercise of the Successor Option the Employee would receive
the same number of shares of the successor's/Parent's common stock as the
Employee would have received had the Employee exercised the Terminated Option
immediately prior to the transaction resulting in the Change in Control and
received shares of such successor/Parent in such transaction. The aggregate
exercise price for all of the shares covered by such Successor Option shall
equal the aggregate exercise price of the Terminated Option; or

                  (ii)  Pay the Employee a bonus within ten (10) days after the
consummation of the Change in Control in an amount agreed to by the Employee and
the Company. Such amount shall be at least equivalent on an after-tax basis to
the net after-tax gain that the Employee would have realized if he had been
issued a Successor Option under clause (i) above and had immediately exercised
such Successor Option and sold the underlying stock, taking into account the
different tax rates that apply to such bonus and to such gain, and such amount
shall also reflect other differences to the Employee between receiving a bonus
under this clause (ii) and receiving a Successor Option under clause (i) above.

            (b)   Definitions. For the purposes of this Agreement, a Change in
Control shall be deemed to have occurred if (i) there shall be consummated (aa)
any reorganization, liquidation or consolidation of the Company, or any merger
or other business combination of the Company with any other corporation, other
than any such merger or other combination that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or if
(ii) any "person" (as defined in Section 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), shall become the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of fifty percent (50%) or more of the Company's outstanding
voting securities (except that for purposes of this Section 10(b), "person"
shall not include any person or any person that controls, is controlled by or is
under common control with such person, who as of the date of this Agreement owns
ten percent (10%) or more of the total voting power represented by the
outstanding voting securities of the Company, or a trustee or other fiduciary
holding securities under any employee benefit plan of the Company, or a
corporation that is owned directly or indirectly by the stockholders of the
Company in substantially the same percentage as their ownership of the Company)
or if (iii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the entire Board shall cease for any reason
to constitute at least one-half of the


                                       9
<PAGE>   10
membership thereof unless the election, or the nomination for election by the
Company's shareholders, of each new director was approved by a vote of at least
one-half of the directors then still in office who were directors at the
beginning of the period.

            The term "Parent" means a corporation, partnership, trust, limited
liability company or other entity that is the ultimate "beneficial owner" (as
defined above) of fifty percent (50%) or more of the Company's outstanding
voting securities.

      11.   Gross Up Payments. If all or any portion of any payment or benefit
that the Employee is entitled to receive from the Company pursuant to this
Agreement (a "Payment") constitutes an "excess parachute payment" within the
meaning of Section 280G of the Code, and as such is subject to the excise tax
imposed by Section 4999 of the Code or to any similar Federal, state or local
tax or assessment (the "Excise Tax"), the Company or its successors or assigns
shall pay to the Employee an additional amount (the "Gross-Up Payment") with
respect to such Payment. The amount of the Gross-Up Payment shall be sufficient
that, after paying (a) any Excise Tax on the Payment, (b) any Federal, state or
local income or employment taxes and Excise Tax on the Gross-Up Payment, and (c)
any interest and penalties imposed in respect of the Excise Tax, the Employee
shall retain an amount equal to the full amount of the Payment. For the purpose
of determining the amount of any Gross-Up Payment, the Employee shall be deemed
to pay Federal income taxes at the highest marginal rate applicable in the
calendar year in which the Gross-Up Payment is made, and state and local income
taxes at the highest marginal rate applicable in the state and locality where
the Employee resides on the date the Gross-Up Payment is made, net of the
maximum reduction in Federal income taxes that could be obtained from deducting
such state and local taxes.

            The Gross-Up Payment with respect to any Payment shall be paid to
the Employee within ten (10) days after the Internal Revenue Service or any
other taxing authority issues a notice stating that an Excise Tax is due with
respect to the Payment, unless the Company undertakes to challenge the taxing
authority on the applicability of such Excise Tax and indemnifies the Employee
for (a) any amounts ultimately determined to be payable, including the Excise
Tax and any related interest and penalties, (b) all expenses (including
attorneys' and experts' fees) reasonably incurred by the Employee in connection
with such challenge, as such expenses are incurred, and (c) all amounts that the
Employee is required to pay to the taxing authorities during the pendency of
such challenge (such amounts to be repaid by the Employee to the Company if they
are ultimately refunded to the Employee by the taxing authority).

      12.   Non-Competition and Non-Solicitation.

            (a)   In consideration of the provisions hereof, for the period
commencing on the date hereof and ending on the first anniversary of the
termination of this Agreement by the Company with Cause pursuant to Section 7(a)
or by the Employee without Good Reason pursuant to Section 8(b), the Employee
will not, except as specifically provided below, anywhere in any county in any
state in which the Company is engaged in business as of such termination date,
directly or indirectly, acting individually or as the owner, shareholder,
partner or


                                       10
<PAGE>   11
management employee of any entity, (i) engage in the operation of a solid waste
collection, transporting or disposal business, transfer facility, recycling
facility, materials recovery facility or solid waste landfill; (ii) enter the
employ as a manager 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 management salary, commissions or otherwise from,
any business engaged in such activities in such counties; or (iii) 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 or trustee;
provided, however, that the Employee may own, directly or indirectly, solely as
an investment, securities of any business traded on any national securities
exchange or quoted on any NASDAQ market, provided the Employee is not a
controlling person of, or a member of a group which controls, such business and
further provided that the Employee does not, in the aggregate, directly or
indirectly, own two percent (2%) or more of any class of securities of such
business.

            (b)   After termination of this Agreement by the Company with Cause
pursuant to Section 7(a) or by the Employee without Good Reason pursuant to
Section 8(b), the Employee shall not (i) solicit any residential or commercial
customer of the Company to whom the Company provides service pursuant to a
franchise agreement with a public entity in any county in any state in which the
Company is engaged in business as of such termination date, (ii) solicit any
residential or commercial customer of the Company to enter into a solid waste
collection account relationship with a competitor of the Company in any such
county, (iii) solicit any such public entity to enter into a franchise agreement
with any such competitor, (iv) solicit any officer, employee or contractor of
the Company to enter into an employment or contractor agreement with a
competitor of the Company or otherwise interfere in any such relationship, or
(v) solicit on behalf of a competitor of the Company any prospective customer of
the Company that the Employee called on or was involved in soliciting on behalf
of the Company during the Term, in each case until the second anniversary of the
date of such termination, unless otherwise permitted to do so by Section 12(a).

            (c)   If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 12 is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specified words or phrases
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

      13.   Indemnification. As an employee and agent of the Company, the
Employee shall be fully indemnified by the Company to the fullest extent
permitted by applicable law in connection with his employment hereunder.


                                       11
<PAGE>   12
      14.   Survival of Provisions. The obligations of the Company under Section
13 of this Agreement, and of the Employee under Section 12 of this Agreement,
shall survive both the termination of the Employee's employment and this
Agreement.

      15.   No Duty to Mitigate; No Offset. The Employee shall not be required
to mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

      16.   Assignment; Binding Agreement. The Company may assign this Agreement
to any parent, subsidiary, affiliate or successor of the Company. This Agreement
is not assignable by the Employee and is binding on him and his executors and
other legal representatives. This Agreement shall bind the Company and its
successors and assigns and inure to the benefit of the Employee and his heirs,
executors, administrators, personal representatives, legatees or devisees. The
Company shall assign this Agreement to any entity that acquires its assets or
business.

      17.   Notice. Any written notice under this Agreement shall be personally
delivered to the other party or sent by certified or registered mail, return
receipt requested and postage prepaid, to such party at the address set forth in
the records of the Company or to such other address as either party may from
time to time specify by written notice.

      18.   Entire Agreement; Amendments. This Agreement contains the entire
agreement of the parties relating to the Employee's employment and supersedes
all oral or written prior discussions, agreements and understandings of every
nature between them. This Agreement may not be changed except by an agreement in
writing signed by the Company and the Employee.

      19.   Waiver. The waiver of a breach of any provision of this Agreement
shall not operate or as be construed to be a waiver of any other provision or
subsequent breach of this Agreement.

      20.   Governing Law and Jurisdictional Agreement. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of California.

      21.   Severability. In case any one or more of the provisions contained in
this Agreement is, for any reason, held invalid in any respect, such invalidity
shall not affect the validity of any other provision of this Agreement, and such
provision shall be deemed modified to the extent necessary to make it
enforceable.

      22.   Enforcement. It is agreed that it is impossible to measure fully, in
money, the damage which will accrue to the Company in the event of a breach or
threatened breach of Sections 5, 6, or 12 of this Agreement, and, in any action
or proceeding to enforce the provisions of Sections 5, 6 or 12 hereof, the
Employee waives the claim or defense that the Company has an adequate remedy at
law and will not assert the claim or defense that such a


                                       12
<PAGE>   13
remedy at law exists. The Company is entitled to injunctive relief to enforce
the provisions of such sections as well as any and all other remedies available
to it at law or in equity without the posting of any bond. The Employee agrees
that if the Employee breaches any provision of Section 12, the Company may
recover as partial damages all profits realized by the Employee at any time
prior to such recovery on the exercise of any warrant, option or right to
purchase the Company's Common Stock and the subsequent sale of such stock, and
may also cancel all outstanding such warrants, options and rights.

      23.   Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original and both of which together shall constitute
one and the same instrument.

      24.   Due Authorization. The execution of this Agreement has been duly
authorized by the Company by all necessary corporate action.

                              EMPLOYMENT AGREEMENT


      THIS EMPLOYMENT AGREEMENT is made and entered into as of January 13, 1998,
by and between Steven F. Bouck (the "Employee") and Waste Connections, Inc., a
Delaware corporation (the "Company"), with reference to the following facts.

      The Company desires to engage the services and employment of the Employee
for the period provided in this Agreement, and the Employee is willing to accept
employment by the Company for such period, on the terms and conditions set forth
below.

      NOW THEREFORE, in consideration of the premises and the mutual covenants
and conditions herein, the Company and the Employee agree as follows:

      1.    Employment. The Company agrees to employ the Employee, and the
Employee agrees to accept employment with the Company, for the Term stated in
Section 3 hereof and on the other terms and conditions herein.

      2.    Position and Responsibilities. During the Term, the Employee shall
serve as Executive Vice President and Chief Financial Officer of the Company,
reporting directly to the Company's President, and perform such other duties and
responsibilities as the President or the Board of Directors (the "Board") of the
Company may reasonably assign to the Employee from time to time. The Employee
shall be based at the Company's corporate headquarters in Roseville, California.
The Employee shall devote such time and attention to his duties as are necessary
to the proper discharge of his responsibilities hereunder. The Employee agrees
to perform all duties consistent with (a) policies established from time to time
by the Company and (b) all applicable legal requirements. At the discretion of
the President and the Board, the Employee shall attend Board meetings, except
during executive sessions of the Board as determined by the Board, and shall
make presentations to the Board from time to time.

            The Company recognizes and accepts that the Employee may, for a
period of time not to exceed 90 days (the "Transition Period"), engage in such
activities as are reasonably necessary to assist his previous employer in
transferring the Employee's responsibilities to his successor. The Employee
agrees to make every effort to minimize the effect of these transition
activities on the Company and to perform fully his obligations hereunder during
the Transition Period. The Employee agrees that either he or his previous
employer shall be responsible for all costs incurred by the Employee or his
previous employer in connection with the Employee's providing such transition
assistance, including, but not limited to, travel costs.

      3.    Term. The period of the Employee's employment under this Agreement
(the "Term") shall commence on March 1, 1998, or earlier by agreement between
the Employee and the Company, and shall continue through February 28, 2001,
unless terminated earlier as provided herein. At the end of the initial Term,
this Agreement shall be renewed automatically 


                                       1
<PAGE>   2
for successive Terms of one year, unless either party shall have given the
other notice of termination hereof as provided herein.

      4.    Compensation, Benefits and Reimbursement of Expenses.

            (a)   Compensation. The Company shall compensate the Employee during
the Term of this Agreement as follows:

                  (1)   Base Salary. The Employee shall be paid a base salary
("Base Salary") of not less than One Hundred Fifteen Thousand Dollars ($115,000)
per year in installments consistent with the Company's usual practices. On the
first anniversary of the Employee's employment by the Company, the Employee's
Base Salary shall be increased to One Hundred Thirty-Five Thousand Dollars
($135,000) per year. Thereafter, the Board shall review the Employee's Base
Salary on March 1 of each year or more frequently, at the times prescribed in
salary administration practices applied generally to management employees of the
Company.

                  (2)   Performance Bonus. The Employee shall be entitled to an
annual cash bonus (the "Bonus") based on the Company's attainment of financial
objectives to be determined annually by the Board. The maximum annual Bonus will
equal thirty-five percent (35%) of the applicable year's ending Base Salary and
will be payable if the Board determines, in its sole and exclusive discretion,
that that year's financial objectives have been fully met. Notwithstanding the
foregoing, for calendar 1998, the Employee will be guaranteed a minimum Bonus of
twenty percent (20%) of the Base Salary paid to the Employee during that year,
and will be paid on a schedule agreed to by the Company and the Employee. The
Bonus with respect to 1999 and each year thereafter shall be paid in February of
the following year.

                  (3)   Signing Bonus. The Employee shall be entitled to a cash
signing bonus in the amount of $69,166, payable no later than March 1, 1998.

                  (4)   Grant of Options. On the first day of the initial Term,
the Company shall grant to the Employee, for no additional consideration, stock
options (the "Options") to purchase 200,000 shares of the Company's Common Stock
under the Company's Stock Option Plan. The Options shall have a term of 10 years
from the date of such grant. Options to purchase 100,000 of the 200,000 shares
of Common Stock shall be exercisable at a price of $2.80 per share and shall
vest and become exercisable with respect to 33,333 such shares on each of
October 1, 1998, and October 1, 1999, and with respect to 33,334 such shares on
October 1, 2000. Options to purchase 50,000 of the 200,000 shares shall be
exercisable at a price of $9.50 per share and shall vest and become exercisable
with respect to 16,667 such shares on October 1, 1998, with respect to 16,667
such shares on October 1, 1999, and with respect to 16,666 such shares on
October 1, 2000. Options to purchase 50,000 of the 200,000 shares shall be
exercisable at a price of $12.50 per share and shall vest and become exercisable
with respect to 16,667 such shares on October 1, 1998, with respect to 16,667
such shares on October 1, 1999, and with respect to 16,666 such shares on
October 1, 2000. The Options shall 


                                       2
<PAGE>   3
be incentive stock options to the extent permitted under the Company's Stock
Option Plan, and the terms of the Options shall be described in more detail in
Stock Option Agreements to be entered into between the Employee and the Company.
If at any time while any of the Options are still outstanding the Company amends
its Stock Option Plan to provide for a less favorable vesting schedule for stock
options than that provided herein, any Options then outstanding shall thereupon
be converted to warrants entitling the Employee to purchase the number of shares
of Common Stock for which the Employee's then outstanding Options may be
exercised, on the same terms as provided under such Options.

                  (5)   Contingent Option Grant. If (i) the Employee's previous
employer announces an acquisition before February 15, 1998, (ii) such
acquisition closes within 60 days after the commencement of the initial Term,
and (iii) the acquisition is one with respect to which, under the Employee's
employment agreement with his previous employer, the Employee would normally
have received additional compensation, but the Employee's previous employer does
not in this case compensate the Employee, the Company shall grant to the
Employee, for no additional consideration, within 30 days after it has been
conclusively determined that the Employee's previous employer will not pay such
additional compensation, stock options (the "Contingent Options") to purchase
30,000 shares of the Company's Common Stock under the Company's Stock Option
Plan. The Contingent Options shall have a term of 10 years from the date of such
grant, shall be exercisable at a price of $2.80 per share, and shall vest and
become exercisable with respect to 10,000 such shares on each of October 1,
1998, October 1, 1999, and October 1, 2000. The Contingent Options shall be
incentive stock options to the extent permitted under the Company's Stock Option
Plan, and the terms of the Contingent Options shall be described in more detail
in Stock Option Agreements to be entered into between the Employee and the
Company. If at any time while any of the Contingent Options are still
outstanding the Company amends its Stock Option Plan to provide for a less
favorable vesting schedule for stock options than that provided herein, any
Contingent Options then outstanding shall thereupon be converted to warrants
entitling the Employee to purchase the number of shares of Common Stock for
which the Employee's then outstanding Contingent Options may be exercised, on
the same terms as provided under such Contingent Options.

            If the Employee's employment by the Company is terminated by the
Company without Cause (as defined in Section 7(a)) before all of the Options or
Contingent Options have vested, all of the outstanding Options and Contingent
Options shall become vested on such termination. If the Employee's employment by
the Company is terminated by the Company for Cause or by the Employee before all
of the Options or Contingent Options have vested, the Employee shall forfeit any
Options (but not any Contingent Options) that are unvested as of the termination
date.

            (b)   Other Benefits. During the Term, the Company shall provide the
Employee with a cellular telephone and will pay or reimburse the Employee's
monthly service fees and costs of calls attributable to Company business. During
the Term, the Employee shall be entitled to receive all other benefits of
employment generally available to other management 


                                       3
<PAGE>   4
employees of the Company and those benefits for which management employees are
or shall become eligible, including, without limitation and to the extent made
available by the Company, medical, dental, disability and prescription coverage,
life insurance and tax-qualified retirement benefits. The Employee shall be
entitled to two (2) weeks of paid vacation in his first twelve months of
employment by the Company, three (3) weeks during each of the second through the
fifth twelve-month periods of employment, and four (4) weeks per twelve-month
period beginning with the sixth twelve-month period of employment.

            (c)   Reimbursement of Other Expenses. The Company agrees to pay or
reimburse the Employee for all reasonable travel and other expenses (including
mileage for business use of employee's personal automobile at the maximum rate
permitted under Internal Revenue Service regulations) incurred by the Employee
in connection with the performance of his duties under this Agreement on
presentation of proper expense statements or vouchers. All such supporting
information shall comply with all applicable Company policies relating to
reimbursement for travel and other expenses.

            (d)   Withholding. All compensation payable to the Employee
hereunder is subject to all withholding requirements under applicable law.

      5.    Confidentiality. During the Term, and at all times thereafter, the
Employee shall not, without the prior written consent of the Company, divulge to
any third party or use for his own benefit or the benefit of any third party or
for any purpose other than the exclusive benefit of the Company, any
confidential or proprietary business or technical information revealed, obtained
or developed in the course of his employment with the Company and which is
otherwise the property of the Company or any of its affiliated corporations,
including, but not limited to, trade secrets, customer lists, formulae and
processes of manufacture; provided, however, that nothing herein contained shall
restrict the Employee's ability to make such disclosures during the course of
his employment as may be necessary or appropriate to the effective and efficient
discharge of his duties to the Company.

      6.    Property. Both during the Term and thereafter, the Employee shall
not remove from the Company's offices or premises any Company documents,
records, notebooks, files, correspondence, reports, memoranda and similar
materials or property of any kind unless necessary in accordance with the duties
and responsibilities of his employment. In the event that any such material or
property is removed, it shall be returned to its proper file or place of
safekeeping as promptly as possible. The Employee shall not make, retain, remove
or distribute any copies, or divulge to any third person the nature or contents
of any of the foregoing or of any other oral or written information to which he
may have access, except as disclosure shall be necessary in the performance of
his assigned duties. On the termination of his employment with the Company, the
Employee shall leave with or return to the Company all originals and copies of
the foregoing then in his possession or subject to his control, whether prepared
by the Employee or by others.

      7.    Termination By Company.

            (a)   Termination for Cause. The employment of the Employee may be
terminated for Cause at any time by the Board; provided, however, that before
the Company may terminate the Employee's employment for Cause for any reason
that is susceptible to cure, the Company shall first send the Employee written
notice of its intention to terminate this Agreement for Cause, specifying in
such notice the reasons for such Cause and those conditions that, if satisfied
by the Employee, would cure the reasons for such Cause, and the Employee shall
have 60 days from receipt of such written notice to satisfy such conditions. If
such conditions are satisfied within such 60-day period, the Company shall so
advise the Employee in writing. If such conditions are not satisfied within such
60-day period, the Company may thereafter terminate this Agreement for Cause on
written Notice of Termination (as defined in Section 9(a)) delivered to the
Employee describing with specificity the grounds for termination. Immediately on
termination pursuant to this Section 7(a), the Company shall pay to the Employee
in a lump sum his then current Base Salary under Section 4(a)(1) on a prorated
basis to the Date of Termination (as defined in Section 9(b)). On termination
pursuant to this Section 7(a), the Employee shall forfeit (i) his Bonus under
Section 4(a)(2) for the year in which such termination occurs, and (ii) all
outstanding but unvested Options (but not Contingent Options) and other options
and rights relating to capital stock of the Company. For purposes of this
Agreement, Cause shall mean:

                  (1)   a material breach of any of the terms of this Agreement
that is not immediately corrected following written notice of default specifying
such breach;

                  (2)   a breach of any of the provisions of Section 12;

                  (3)   repeated intoxication with alcohol or drugs while on
Company premises during its regular business hours to such a degree that, in the
reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

                  (4)   conviction of a felony; or

                  (5)   misappropriation of property belonging to the Company
and/or any of its affiliates.

            (b)   Termination Without Cause. The employment of the Employee may
be terminated without Cause at any time by the Board on delivery to the Employee
of a written Notice of Termination (as defined in Section 9(a)). On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(b), the
Company shall pay to the Employee in a lump sum an amount equal to the sum of
(i) all Base Salary payable under Section 4(a)(1) through the termination date,
(ii) a pro-rated portion of the maximum Bonus available to the Employee under
Section 4(a)(2) for the year in which the termination occurs, and (iii) an
amount equal to the 


                                       5
<PAGE>   6
greater of (aa) the aggregate Total Compensation paid to the Employee by the
Company with respect to the twelve months preceding the termination date, or
(bb) the aggregate Remaining Compensation payable to the Employee by the Company
for the balance of the Term remaining under this Agreement. For purposes of this
section 7(b), the Employee's Total Compensation shall equal the sum of the Base
Salary, Bonus, and other benefits and expense reimbursements described in
Section 4(b) paid to the Employee by the Company. For purposes of this section
7(b), the Remaining Compensation for the balance of the Term shall equal the sum
of the Base Salary and Bonus payable to the Employee under the remaining Term of
this Agreement, assuming that the Employee would receive for the remaining Term
the same Base Salary and Bonus earned by the Employee with respect to the
previous year, unless otherwise specified in this Agreement. In addition, on
termination of the Employee under this Section 7(b), all of the Employee's
outstanding but unvested Options, Contingent Options and other options and
rights relating to capital stock of the Company shall immediately vest and
become exercisable. The term of any such options and rights shall be extended to
the third anniversary of the Employee's termination. The Employee acknowledges
that extending the term of any Options or Contingent Options pursuant to this
Section 7(b) or Section 7(c) or Section 7(d) could cause such Options or
Contingent Options to lose their tax-qualified status if they are incentive
stock options under the Code and agrees that the Company shall have no
obligation to compensate the Employee for any additional taxes he incurs as a
result.

            (c)   Termination on Disability. If during the Term the Employee
should fail to perform his duties hereunder on account of physical or mental
illness or other incapacity which the Board shall in good faith determine
renders the Employee incapable of performing his duties hereunder, and such
illness or other incapacity shall continue for a period of more than six (6)
consecutive months ("Disability"), the Company shall have the right, on written
Notice of Termination (as defined in Section 9(a)) delivered to the Employee to
terminate the Employee's employment under this Agreement. During the period that
the Employee shall have been incapacitated due to physical or mental illness,
the Employee shall continue to receive the full Base Salary provided for in
Section 4(a)(1) hereof at the rate then in effect until the Date of Termination
(as defined in Section 9(b)) pursuant to this Section 7(c). On the Date of
Termination pursuant to this Section 7(c), the Company shall pay to the Employee
in a lump sum an amount equal to (i) the Base Salary remaining payable to the
Employee under Section 4(a)(1) for the full remaining Term, plus (ii) a
pro-rated portion of the maximum Bonus available to the Employee under Section
4(a)(2) for the year in which the termination occurs. In addition, on such
termination, all of the Employee's outstanding but unvested Options, Contingent
Options and other options and rights relating to capital stock of the Company
shall immediately vest and become exercisable. The term of any such options and
rights shall be extended to the third anniversary of the Employee's termination.

            (d)   Termination on Death. If the Employee shall die during the
Term, the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) 


                                       6
<PAGE>   7
hereof. In addition, on termination of the Employee under this Section 7(d), all
of the Employee's outstanding but unvested Options, Contingent Options and other
options and rights relating to capital stock of the Company shall immediately
vest and become exercisable. The term of any such options and rights shall be
extended to the third anniversary of the Employee's termination. The provisions
of this Section 7(d) shall not affect the entitlements of the Employee's heirs,
executors, administrators, legatees, beneficiaries or assigns under any employee
benefit plan, fund or program of the Company.

      8.    Termination By Employee. The Employee may terminate his employment
hereunder on written Notice of Termination delivered to the Company setting
forth the effective date of termination. If the Employee terminates his
employment hereunder, he shall be entitled to receive, and the Company agrees to
pay on the effective date of termination specified in the Notice of Termination,
his current Base Salary under Section 4(a)(1) hereof on a prorated basis to such
date of termination. On termination by the Employee, the Employee shall forfeit
(i) his Bonus under Section 4(a)(2) for the year in which such termination
occurs and (ii) all outstanding but unvested Options (but not any Contingent
Options) and other options and rights relating to capital stock of the Company.

      9.    Provisions Applicable to Termination of Employment.

            (a)   Notice of Termination. Any purported termination of Employee's
employment by the Company pursuant to Section 7 shall be communicated by Notice
of Termination to the Employee as provided herein, and shall state the specific
termination provisions in this Agreement relied on and set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Employee's employment ("Notice of Termination"). If the Employee terminates
under Section 8, he shall give the Company a Notice of Termination.

            (b)   Date of Termination. For all purposes, "Date of Termination"
shall mean, for Disability, thirty (30) days after Notice of Termination is
given to the Employee (provided the Employee has not returned to duty on a
full-time basis during such 30-day period), or, if the Employee's employment is
terminated by the Company for any other reason or by the Employee, the date on
which a Notice of Termination is given.

            (c)   Benefits on Termination. On termination of this Agreement by
the Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

      10.   Change In Control.


                                       7
<PAGE>   8
            (a)   Payments on Change in Control. Notwithstanding any provision
in this Agreement to the contrary, unless the Employee elects in writing to
waive this provision, a Change in Control (as defined below) of the Company
shall be deemed a termination of the Employee without Cause, and the Employee
shall be entitled to receive and the Company agrees to pay to the Employee in a
lump sum the same amount determined under Section 7(b) that is payable to the
Employee on termination without Cause. In addition, on a Change of Control, all
of the Employee's outstanding but unvested Options, Contingent Options and other
options and rights relating to capital stock of the Company shall immediately
vest and become exercisable, the term of any such options and rights shall be
extended to the third anniversary of the Employee's termination.

            After a Change in Control, if any previously outstanding Option,
Contingent Option or other option or right (the "Terminated Option") relating to
the Company's capital stock does not remain outstanding, the successor to the
Company or its then Parent (as defined below) shall either:

                  (i)   Issue an option, warrant or right, as appropriate (the
"Successor Option"), to purchase common stock of such successor or Parent in an
amount such that on exercise of the Successor Option the Employee would receive
the same number of shares of the successor's/Parent's common stock as the
Employee would have received had the Employee exercised the Terminated Option
immediately prior to the transaction resulting in the Change in Control and
received shares of such successor/Parent in such transaction. The aggregate
exercise price for all of the shares covered by such Successor Option shall
equal the aggregate exercise price of the Terminated Option; or

                  (ii)  Pay the Employee a bonus within ten (10) days after the
consummation of the Change in Control in an amount agreed to by the Employee and
the Company. Such amount shall be at least equivalent on an after-tax basis to
the net after-tax gain that the Employee would have realized if he had been
issued a Successor Option under clause (i) above and had immediately exercised
such Successor Option and sold the underlying stock, taking into account the
different tax rates that apply to such bonus and to such gain, and such amount
shall also reflect other differences to the Employee between receiving a bonus
under this clause (ii) and receiving a Successor Option under clause (i) above.

            (b)   Definitions. For the purposes of this Agreement, a Change in
Control shall be deemed to have occurred if (i) there shall be consummated (aa)
any reorganization, liquidation or consolidation of the Company, or any merger
or other business combination of the Company with any other corporation, other
than any such merger or other combination that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one 


                                       8
<PAGE>   9
transaction or a series of related transactions) of all, or substantially all,
of the assets of the Company, or if (ii) any "person" (as defined in Section
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")), shall become the "beneficial owner" (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of fifty percent (50%) or more
of the Company's outstanding voting securities (except that for purposes of this
Section 10(b), "person" shall not include any person (or any person that
controls, is controlled by or is under common control with such person) who as
of the date of this Agreement owns ten percent (10%) or more of the total voting
power represented by the outstanding voting securities of the Company, or a
trustee or other fiduciary holding securities under any employee benefit plan of
the Company, or a corporation that is owned directly or indirectly by the
stockholders of the Company in substantially the same percentage as their
ownership of the Company) or if (iii) during any period of two consecutive
years, individuals who at the beginning of such period constituted the entire
Board shall cease for any reason to constitute at least one-half of the
membership thereof unless the election, or the nomination for election by the
Company's shareholders, of each new director was approved by a vote of at least
one-half of the directors then still in office who were directors at the
beginning of the period.

            The term "Parent" means a corporation, partnership, trust, limited
liability company or other entity that is the ultimate "beneficial owner" (as
defined above) of fifty percent (50%) or more of the Company's outstanding
voting securities.

      11.   Gross Up Payments. If all or any portion of any payment or benefit
that the Employee is entitled to receive from the Company pursuant to this
Agreement (a "Payment") constitutes an "excess parachute payment" within the
meaning of Section 280G of the Code, and as such is subject to the excise tax
imposed by Section 4999 of the Code or to any similar Federal, state or local
tax or assessment (the "Excise Tax"), the Company or its successors or assigns
shall pay to the Employee an additional amount (the "Gross-Up Payment") with
respect to such Payment. The amount of the Gross-Up Payment shall be sufficient
that, after paying (a) any Excise Tax on the Payment, (b) any Federal, state or
local income or employment taxes and Excise Tax on the Gross-Up Payment, and (c)
any interest and penalties imposed in respect of the Excise Tax, the Employee
shall retain an amount equal to the full amount of the Payment. For the purpose
of determining the amount of any Gross-Up Payment, the Employee shall be deemed
to pay Federal income taxes at the highest marginal rate applicable in the
calendar year in which the Gross-Up Payment is made, and state and local income
taxes at the highest marginal rate applicable in the state and locality where
the Employee resides on the date the Gross-Up Payment is made, net of the
maximum reduction in Federal income taxes that could be obtained from deducting
such state and local taxes.

            The Gross-Up Payment with respect to any Payment shall be paid to
the Employee within ten (10) days after the Internal Revenue Service or any
other taxing authority issues a notice stating that an Excise Tax is due with
respect to the Payment, unless the Company undertakes to challenge the taxing
authority on the applicability of such Excise Tax and indemnifies the Employee
for (a) any amounts ultimately determined to be payable, including the 


                                       9
<PAGE>   10
Excise Tax and any related interest and penalties, (b) all expenses (including
attorneys' and experts' fees) reasonably incurred by the Employee in connection
with such challenge, as such expenses are incurred, and (c) all amounts that the
Employee is required to pay to the taxing authorities during the pendency of
such challenge (such amounts to be repaid by the Employee to the Company if they
are ultimately refunded to the Employee by the taxing authority).

      12.   Non-Competition and Non-Solicitation.

            (a)   In consideration of the provisions hereof, for the period
commencing on the date hereof and ending on the first anniversary of the
termination of this Agreement by the Company with Cause pursuant to Section 7(a)
or by the Employee pursuant to Section 8, the Employee will not, except as
specifically provided below, anywhere in any county in any state in which the
Company is engaged in business as of such termination date, directly or
indirectly, acting individually or as the owner, shareholder, partner or
management employee of any entity, (i) engage in the operation of a solid waste
collection, transporting or disposal business, transfer facility, recycling
facility, materials recovery facility or solid waste landfill; (ii) enter the
employ as a manager 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 management salary, commissions or otherwise from,
any business engaged in such activities in such counties; or (iii) 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 or trustee;
provided, however, that the Employee may own, directly or indirectly, solely as
an investment, securities of any business traded on any national securities
exchange or quoted on any NASDAQ market, provided the Employee is not a
controlling person of, or a member of a group which controls, such business and
further provided that the Employee does not, in the aggregate, directly or
indirectly, own two percent (2%) or more of any class of securities of such
business.

            (b)   After termination of this Agreement by the Company with Cause
pursuant to Section 7(a) or by the Employee pursuant to Section 8, the Employee
shall not (i) solicit any residential or commercial customer of the Company to
whom the Company provides service pursuant to a franchise agreement with a
public entity in any county in any state in which the Company is engaged in
business as of such termination date, (ii) solicit any residential or commercial
customer of the Company to enter into a solid waste collection account
relationship with a competitor of the Company in any such county, (iii) solicit
any such public entity to enter into a franchise agreement with any such
competitor, (iv) solicit any officer, employee or contractor of the Company to
enter into an employment or contractor agreement with a competitor of the
Company or otherwise interfere in any such relationship, or (v) solicit on
behalf of a competitor of the Company any prospective customer of the Company
that the Employee called on or was involved in soliciting on behalf of the
Company during the Term, in each case until the second anniversary of the date
of such termination, unless otherwise permitted to do so by Section 12(a).


                                       10
<PAGE>   11
            (c)   If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 12 is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specified words or phrases
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

      13.   Indemnification. As an employee and agent of the Company, the
Employee shall be fully indemnified by the Company to the fullest extent
permitted by applicable law in connection with his employment hereunder.

      14.   Survival of Provisions. The obligations of the Company under Section
13 of this Agreement, and of the Employee under Section 12 of this Agreement,
shall survive both the termination of the Employee's employment and this
Agreement.

      15.   Equity Investment by the Employee. On the first day of the initial
Term, the Company shall sell to the Employee, for $2.80 per share in cash, up to
50,000 shares of the Company's Common Stock, at the Employee's election, but
subject to any approvals of the Company's existing stockholders required under
the Company's existing agreements with such stockholders.

      16.   No Duty to Mitigate; No Offset. The Employee shall not be required
to mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

      17.   Assignment; Binding Agreement. The Company may assign this Agreement
to any parent, subsidiary, affiliate or successor of the Company. This Agreement
is not assignable by the Employee and is binding on him and his executors and
other legal representatives. This Agreement shall bind the Company and its
successors and assigns and inure to the benefit of the Employee and his heirs,
executors, administrators, personal representatives, legatees or devisees. The
Company shall assign this Agreement to any entity that acquires its assets or
business.

      18.   Notice. Any written notice under this Agreement shall be personally
delivered to the other party or sent by certified or registered mail, return
receipt requested and postage prepaid, to such party at the address set forth in
the records of the Company or to such other address as either party may from
time to time specify by written notice.

      19.   Entire Agreement; Amendments. This Agreement contains the entire
agreement of the parties relating to the Employee's employment and supersedes
all oral or written prior 


                                       11
<PAGE>   12
discussions, agreements and understandings of every nature between them. This
Agreement may not be changed except by an agreement in writing signed by the
Company and the Employee.

      20.   Waiver. The waiver of a breach of any provision of this Agreement
shall not operate or as be construed to be a waiver of any other provision or
subsequent breach of this Agreement.

      21.   Governing Law and Jurisdictional Agreement. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of California.

      22.   Severability. In case any one or more of the provisions contained in
this Agreement is, for any reason, held invalid in any respect, such invalidity
shall not affect the validity of any other provision of this Agreement, and such
provision shall be deemed modified to the extent necessary to make it
enforceable.

      23.   Enforcement. It is agreed that it is impossible to measure fully, in
money, the damage which will accrue to the Company in the event of a breach or
threatened breach of Sections 5, 6, or 12 of this Agreement, and, in any action
or proceeding to enforce the provisions of Sections 5, 6 or 12 hereof, the
Employee waives the claim or defense that the Company has an adequate remedy at
law and will not assert the claim or defense that such a remedy at law exists.
The Company is entitled to injunctive relief to enforce the provisions of such
sections as well as any and all other remedies available to it at law or in
equity without the posting of any bond. The Employee agrees that if the Employee
breaches any provision of Section 12, the Company may recover as partial damages
all profits realized by the Employee at any time prior to such recovery on the
exercise of any warrant, option or right to purchase the Company's Common Stock
and the subsequent sale of such stock, and may also cancel all outstanding such
warrants, options and rights.

      24.   Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original and both of which together shall constitute
one and the same instrument.

limitation, any severance compensation or Bonus Compensation. Any stock options

Agreement.

            5.4 Disability. If, in the reasonable judgment of the Company, the

hereunder because of any physical, mental or legal disability (including

of or suffered by the Company, if a surviving or resulting corporation or other
entity or person continues (or resumes after a period of not more than sixty
days) the business of the Company. In any such event, if the business of the
Company is so continued or so resumed, this Agreement shall be binding on and
shall inure to the benefit of the corporation or other entity or person
surviving or resulting or to which such assets shall have been transferred and
the Employee shall be an employee of that part or division of such corporation
or other entity or person that shall have been the Company immediately prior to
such transaction. If, in any such event, the business of the Company is not so
continued or so resumed, such event shall be deemed to constitute termination
without cause by the Company as provided in Section 5.2.

      6.  Trade Secrets, Patents, Competition, Etc.

            6.1 Trade Secrets. The Employee acknowledges that as an employee of

                  The Employee represents, warrants and agrees that he will not
at any time, whether during or subsequent to the term of his employment by the
Company, without the specific written consent of the Company in the particular
case, directly or indirectly use, disclose or communicate to any person or
entity any Trade Secrets, for any purpose, except such as have been publicly
disclosed through no act or omission of the Employee. The Employee further
acknowledges and agrees that this Section 6 prohibits and precludes any use of
Trade Secrets by him or by any person obtaining any Trade Secrets directly or
indirectly from him in competition with the Company.

                  The Employee further agrees that all written materials,
including without limitation files, records, documents, drawings and
specifications, and all equipment and devices and all other items relating to
the business of the Company, whether prepared by or with the assistance of the
Employee or otherwise coming into his possession, control or knowledge, are and
shall remain the exclusive property of the Company and shall not be removed from
the premises of the Company under any circumstances. On termination of his
employment with the Company for any reason, the Employee agrees to deliver
promptly to the Company all of the foregoing which are or have been in his
possession or under his control.

            6.2 Inventions, Designs and Patents. The Employee further
represents, warrants and agrees that he will fully inform and disclose to the
Company all inventions, designs, improvements and discoveries ("Inventions") of
which he obtains knowledge or information during his employment by the Company
and which relate to the existing or contemplated business of the Company or to
any experimental or developmental work carried on or contemplated by the
Company, whether or not conceived by the Employee alone or with others and
whether or not conceived during regular working hours. All Inventions are and
shall remain the exclusive property of the Company. The Employee agrees to
assist the Company to obtain any and all patents, trademarks, service marks and
copyrights relating to Inventions and to execute all documents and do all things
necessary to obtain letters patent and trademark, service mark and copyright
registrations, to vest the Company with full and exclusive title to each
Invention, and to protect the Inventions against infringement by others, all as
and to the extent the Company may request.

                  Notwithstanding the foregoing provisions of this Section 6.2,
this Section 6.2 shall not apply to an Invention developed entirely on the
Employee's own time without using the Company's equipment, supplies, facilities,
or trade secret information except for those Inventions that either (a) relate
at the time of conception or reduction to practice of the Invention to the
Company's business or demonstrably anticipated research or development of the
Company, or (b) result from any work performed by the Employee for the Company.
The Employee acknowledges that this paragraph constitutes the notification
contemplated by California Labor Code section 2872.

<PAGE>   5

            6.3 Competition and Solicitation. The Employee acknowledges and
agrees that he will not at any time during his employment by the Company
directly or indirectly own an interest in, join, operate, control or participate
in, or be connected as an officer, employee, agent, independent contractor,
consultant, partner, shareholder or principal with, any corporation,
partnership, proprietorship, association, or other entity or person engaged in
developing, producing, designing, providing, soliciting orders for, selling,
distributing or marketing products or services that directly or indirectly
compete with the Company's products, services or business.

                  The Employee further agrees that he will not at any time
during his employment by the Company and if the Employee's employment is
terminated for cause pursuant to Section 5.1, or if Employee voluntarily
terminates employment pursuant to Section 5.3, for a period of five years
following such termination of his employment, directly or indirectly, and
whether or not for compensation, interfere with the business of the Company in
any manner, including, without limitation, (a) by diverting or attempting to
divert from the Company any business in which the Company is engaged or
contemplates engaging, (b) assisting in bidding or negotiating any franchise or
agreement with governmental entities to provide solid waste, collection,
landfill or recycling services in California, or (c) by inducing any employee of
the Company to leave the Company's employ or any consultant or other independent
contractor for the Company to change or terminate any relationship between that
person and the Company. This paragraph shall not apply if this Agreement is not
renewed at the end of its term or if Employee's employment is terminated without
cause pursuant to Section 5.2. Nothing in this paragraph shall be deemed to
modify the Stock Purchase Agreement dated as of February 4, 1998 among the
Company, Madera Disposal Systems, Inc. ("Madera") and the shareholders of Madera
(including Employee), including without limitation Section 11 of that Agreement.

            6.4 No Derogation. The Employee will not in any way or to any person
or entity or governmental or regulatory body or agency, denigrate or derogate
the Company or any of its affiliates 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 Employee 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 may reasonably adversely affect 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
Employee will 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 section does 



                                       5
<PAGE>   6

not apply to the extent that testimony is required by legal process, provided
that the Company has received not less than five days' prior written notice of
such proposed testimony.

            6.5 Injunctive Relief. The Employee acknowledges and agrees that his
failure to perform any of his covenants in this Section 6 would cause
irreparable injury to the Company and cause damages to the Company which would
be difficult or impossible to ascertain or quantify. Accordingly, without
limiting any remedies that may be available with respect to any breach of this
Agreement, the Employee consents to the entry of an injunction to restrain any
breach of this Section 6.

            6.6 Infringement. The Employee represents and warrants that he does
not possess and will not use, in connection with his employment by the Company,
any trade secrets or other confidential or proprietary information or
intellectual property in which any other person has any right, title or interest
and that his employment by the Company as contemplated hereby will not infringe
or violate the rights of any other corporation, partnership, firm,
proprietorship, association or other person.

            6.7 Survival. The representations, warranties and agreements in this
Section 6 shall survive any cancellation, termination, rescission or expiration
of this Agreement and any termination of the Employee's employment with the
Company.

      7. Severability. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provision hereof. The Employee agrees that the provisions of this Agreement are
reasonable and valid in geographic and temporal scope and in all other respects.
If any court determines that any provision of this Agreement, or any part
thereof, is invalid or unenforceable, the remainder of this Agreement shall not
thereby be affected and shall be given full effect, without regard to the
invalid portions. If any court determines that any provision of this Agreement,
or any part thereof, is unenforceable because of duration or geographic scope,
such court shall reduce the duration or scope of such provision to the extent
necessary to render it enforceable and, in its reduced form, such provision
shall then be enforced.

      8. Notices. Except as otherwise specifically provided herein, any notice,
consent, demand or other communication to be given under or in connection with
this Agreement shall be in writing and shall be deemed duly given when delivered
personally, when transmitted by facsimile transmission, one day after being
deposited with Federal Express or other nationally recognized overnight delivery
service or three days after being mailed by first class mail, charges or postage
prepaid, properly addressed, if to the Company, at its principal office, and, if
to the Employee, at his address set forth following his signature below. Either
party may change such address from time to time by notice to the other.



                                       6
<PAGE>   7

      9.  Governing Law.  This Agreement shall be governed by and construed and
interpreted in accordance with the laws of the State of California.

      10. Assignment. Except as otherwise specifically provided herein, neither
party shall assign this Agreement or any rights hereunder without the consent of
the other party, and any attempted or purported assignment without such consent
shall be void; provided that the Employee's consent shall not be required hereby
for any of the transactions to which Section 5.6 hereof refers. This Agreement
shall otherwise bind and inure to the benefit of the parties hereto and their
respective successors, assigns, heirs, legatees, devisees, executors,
administrators and legal representatives.

      11. Specific Enforcement. The Employee is obligated under this Agreement
to render services of a special, unique, unusual, extraordinary and intellectual
character, thereby giving this Agreement peculiar value so that the loss thereof
cannot be reasonably or adequately compensated in damages in an action at law.
Accordingly, in addition to other remedies provided by law, the Company shall
have the right during the term of this Agreement to compel specific performance
by the Employee.

      12. Entire Agreement. This Agreement contains the entire agreement of the
parties and supersedes all prior or contemporaneous negotiations,
correspondence, understandings and agreements between the parties, regarding the
subject matter of this Agreement. This Agreement may not be amended or modified
except in writing signed by both parties and supported by new consideration.

exercisable. For the purposes of this Section 5.3(a), "Good Reason" shall mean:
(i) relocation of Madera Disposal Systems, Inc.'s, principal executive office to
a location more than fifty miles from its present location; or (ii) the failure
of the Company to obtain the assumption of this Agreement by any successor
entity to which it is assigned.

                  (b)   Termination Without Good Reason. If the Employee
terminates his employment hereunder without Good Reason, the Employee shall be
entitled only to his Base Salary hereunder to the date of such termination, and
shall not be entitled to any other compensation, including, without limitation,
any severance compensation or Bonus Compensation. Any stock options granted to
the Employee by the Company shall terminate upon the Company's receipt of notice
of the Employee's intent to terminate this Agreement.

            5.4   Disability. If, in the reasonable judgment of the Company, the
Employee becomes unable to perform competently and efficiently his duties
hereunder because of any physical, mental or legal disability (including
sickness or an injunction or similar order or decree of a court of competent
jurisdiction preventing or severely impairing the performance of his duties
hereunder) that lasts for six (6) consecutive months (the "Disability Period"),
he shall be entitled to the greater of his compensation hereunder for the
remainder of the term of this Agreement or one year's Base Salary. Any stock
options granted to the Employee by the Company shall vest on the last day of the
Disability Period. The Employee shall not be entitled 


                                       3
<PAGE>   4
to any other compensation, including, without limitation, any severance
compensation or Bonus Compensation.

            5.5   Death. In the event of the death of the Employee, the
Employee's heirs, legatees, devisees, executors or legal representatives shall
be entitled to the greater of the Employee's compensation hereunder for the
remainder of the term of this Agreement or one year's Base Salary. Any stock
options granted to the Employee by the Company shall vest on the day of the
Employee's death. The Employee's heirs, legatees, devisees, executors,
administrators and legal representatives shall not be entitled to any other
compensation, including, without limitation, any severance compensation or Bonus
Compensation.

            5.6   Merger; Sale of Assets. This Agreement shall not be terminated
by any voluntary or involuntary dissolution, reorganization, merger,
consolidation or transfer of assets of the Company, or by any other act or event
of or suffered by the Company, if a surviving or resulting corporation or other
entity or person continues (or resumes after a period of not more than sixty
days) the business of the Company. In any such event, if the business of the
Company is so continued or so resumed, this Agreement shall be binding on and
shall inure to the benefit of the corporation or other entity or person
surviving or resulting or to which such assets shall have been transferred and
the Employee shall be an employee of that part or division of such corporation
or other entity or person that shall have been the Company immediately prior to
such transaction. If, in any such event, the business of the Company is not so
continued or so resumed, such event shall be deemed to constitute termination
without cause by the Company as provided in Section 5.2.

      6.    Trade Secrets, Patents, Competition, Etc.

            6.1   Trade Secrets. The Employee acknowledges that as an employee
of the Company he has had and will have access to and has and will become
acquainted with various trade secrets and other proprietary and confidential
information of the Company (the "Trade Secrets"), which may consist of, among
other things, designs, equipment, devices, patterns, electronically recordable
data or concepts, computer programs and software, software enhancements,
modifications and improvements, secret inventions, processes, compilations of
information, books, papers, records and specifications, names, buying habits and
practices of customers or potential customers of the Company, marketing methods,
operating practices and related data, names of vendors and suppliers names,
names of acquisition targets, costs of materials, prices the Company obtains or
has obtained or at which it sells or has sold its services, sales costs, lists
or other written records used in the Company's business, compensation paid to
Company employees and consultants and other terms of employment, all of which
are owned by the Company and are regularly used or contemplated to be used in
the business of the Company.

                  The Employee represents, warrants and agrees that he will not
at any time, whether during or subsequent to the term of his employment by the
Company, without the specific written consent of the Company in the particular
case, directly or indirectly use, disclose or communicate to any person or
entity any Trade Secrets, for any purpose, except such as have been publicly
disclosed through no act or omission of the Employee. The Employee further
acknowledges and agrees that this Section 6 prohibits and precludes any use of
Trade Secrets by him or by any person obtaining any Trade Secrets directly or
indirectly from him in competition with the Company.

                  The Employee further agrees that all written materials,
including without limitation files, records, documents, drawings and
specifications, and all equipment and devices and all other items relating to
the business of the Company, whether prepared by or with the assistance of the
Employee or otherwise coming into his possession, control or knowledge, are and
shall remain the exclusive property of the Company and shall not be removed from
the premises of the Company under any circumstances. On termination of his
employment with the Company for any reason, the Employee agrees to deliver
promptly to the Company all of the foregoing which are or have been in his
possession or under his control.

            6.2   Inventions, Designs and Patents. The Employee further
represents, warrants and agrees that he will fully inform and disclose to the
Company all inventions, designs, improvements and discoveries ("Inventions") of
which he obtains knowledge or information during his employment by the Company
and which relate to the existing or contemplated business of the Company or to
any experimental or developmental work carried on or contemplated by the
Company, whether or not conceived by the Employee alone or with others and
whether or not conceived during regular working hours. All Inventions are and
shall remain the exclusive property of the Company. The Employee agrees to
assist the Company to obtain any and all patents, trademarks, service marks and
copyrights relating to Inventions and to execute all documents and do all things
necessary to obtain letters patent and trademark, service mark and copyright
registrations, to vest the Company with full and exclusive title to each
Invention, and to protect the Inventions against infringement by others, all as
and to the extent the Company may request.

                  Notwithstanding the foregoing provisions of this Section 6.2,
this Section 6.2 shall not apply to an Invention developed entirely on the
Employee's own time without using the Company's equipment, supplies, facilities,
or trade secret information except for those Inventions that either (a) relate
at the time of conception or reduction to practice of the Invention to the
Company's business or demonstrably anticipated research or development of the
Company, or (b) result from any work performed by the Employee for the Company.
The Employee acknowledges that this paragraph constitutes the notification
contemplated by California Labor Code section 2872.


                                       5
<PAGE>   6
            6.3   Competition and Solicitation. The Employee acknowledges and
agrees that he will not at any time during his employment by the Company
directly or indirectly own an interest in, join, operate, control or participate
in, or be connected as an officer, employee, agent, independent contractor,
consultant, partner, shareholder or principal with, any corporation,
partnership, proprietorship, association, or other entity or person engaged in
developing, producing, designing, providing, soliciting orders for, selling,
distributing or marketing products or services that directly or indirectly
compete with the Company's products, services or business.

                  The Employee further agrees that he will not at any time
during his employment by the Company and for a period of five years following
termination (voluntary or involuntary, whether or not for cause, or otherwise)
of this Agreement or his employment with the Company, directly or indirectly,
and whether or not for compensation, interfere with the business of the Company
in any manner, including, without limitation, (a) by diverting or attempting to
divert from the Company any business in which the Company is engaged or
contemplates engaging, (b) assisting in bidding or negotiating any franchise or
agreement with governmental entities to provide solid waste, collection,
landfill or recycling services in California, or (c) by inducing any employee of
the Company to leave the Company's employ or any consultant or other independent
contractor for the Company to change or terminate any relationship between that
person and the Company. Despite the provisions of this Section 6.3, the Company
agrees that the Employee may continue to operate Youngclaus Enterprises as it is
operated on the date hereof, but the Employee cannot expand the operation of
Youngclaus Enterprises.

            6.4   No Derogation. The Employee will not in any way or to any
person or entity or governmental or regulatory body or agency, denigrate or
derogate the Company or any of its affiliates 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 Employee 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 may reasonably adversely affect 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 Employee will 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 section does not apply to
the extent that testimony is required by legal process, provided that the
Company has received not less than five days' prior written notice of such
proposed testimony.


                                       7
<PAGE>   7
            6.5   Injunctive Relief. The Employee acknowledges and agrees that
his failure to perform any of his covenants in this Section 6 would cause
irreparable injury to the Company and cause damages to the Company which would
be difficult or impossible to ascertain or quantify. Accordingly, without
limiting any remedies that may be available with respect to any breach of this
Agreement, the Employee consents to the entry of an injunction to restrain any
breach of this Section 6.

            6.6   Infringement. The Employee represents and warrants that he
does not possess and will not use, in connection with his employment by the
Company, any trade secrets or other confidential or proprietary information or
intellectual property in which any other person has any right, title or interest
and that his employment by the Company as contemplated hereby will not infringe
or violate the rights of any other corporation, partnership, firm,
proprietorship, association or other person.

            6.7   Survival. The representations, warranties and agreements in
this Section 6 shall survive any cancellation, termination, rescission or
expiration of this Agreement and any termination of the Employee's employment
with the Company.

      7.    Severability. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provision hereof. The Employee agrees that the provisions of this Agreement are
reasonable and valid in geographic and temporal scope and in all other respects.
If any court determines that any provision of this Agreement, or any part
thereof, is invalid or unenforceable, the remainder of this Agreement shall not
thereby be affected and shall be given full effect, without regard to the
invalid portions. If any court determines that any provision of this Agreement,
or any part thereof, is unenforceable because of duration or geographic scope,
such court shall reduce the duration or scope of such provision to the extent
necessary to render it enforceable and, in its reduced form, such provision
shall then be enforced.

      8.    Notices. Except as otherwise specifically provided herein, any
notice, consent, demand or other communication to be given under or in
connection with this Agreement shall be in writing and shall be deemed duly
given when delivered personally, when transmitted by facsimile transmission, one
day after being deposited with Federal Express or other nationally recognized
overnight delivery service or three days after being mailed by first class mail,
charges or postage prepaid, properly addressed, if to the Company, at its
principal office, and, if to the Employee, at his address set forth following
his signature below. Either party may change such address from time to time by
notice to the other.

      9.    Governing Law. This Agreement shall be governed by and construed and
interpreted in accordance with the laws of the State of California.


                                       8
<PAGE>   8
      10.   Assignment; Binding Agreement. The Company may assign this Agreement
to any parent, subsidiary, affiliate or successor of the Company. This Agreement
is not assignable by the Employee and is binding on him and his executors and
other legal representatives. This Agreement shall bind the Company and its
successors and assigns and inure to the benefit of the Employee and his heirs,
executors, administrators, personal representatives, legatees or devisees. The
Company shall assign this Agreement to any entity that acquires its assets or
business.

      11.   Specific Enforcement. The Employee is obligated under this Agreement
to render services of a special, unique, unusual, extraordinary and intellectual
character, thereby giving this Agreement peculiar value so that the loss thereof
cannot be reasonably or adequately compensated in damages in an action at law.
Accordingly, in addition to other remedies provided by law, the Company shall
have the right during the term of this Agreement to compel specific performance
by the Employee.

      12.   Entire Agreement. This Agreement contains the entire agreement of
the parties and supersedes all prior or contemporaneous negotiations,
correspondence, understandings and agreements between the parties, regarding the
subject matter of this Agreement. This Agreement may not be amended or modified
except in writing signed by both parties and supported by new consideration.

            IN WITNESS WHEREOF, this Agreement has been duly executed by or on
behalf of the parties hereto as of the date first above written.

            Capital Note and/or the Continental Working Capital Note, as the
            case may be, shall be immediately amended to reduce the principal
            amount thereof to such new estimated number and to reduce the two
            installments due on such note by one-half of the amount of the
            reduction.

      (b)   Within sixty (60) days after the Closing Date the appropriate Buyer
            shall deliver to BFI a final schedule and calculation ("Final

            Fibres Inventory, OKC Inventory, Idaho Recycling Inventory and Idaho
            Solid Waste Inventory, prepaid items and deposits less all deferred
            revenue of the Company and Fibres and all deferred revenues of BFI
            OKC respecting the Oklahoma City Business and BFI Idaho respecting
            the Idaho Solid Waste Business and Idaho Recycling Business as of

      (c)   Within ten (10) days thereafter, BFI shall deliver to Waste and/or
            Continental, or Waste and/or Continental shall deliver to BFI
            immediately available funds in the amount by which the Final Working
            Capital attributable to the Company Receivables and Fibres
            Receivables is less than or greater than the original principal
            amount of the Waste Working Capital Note and the Fibres Working
            Capital Note, respectively; provided, that if BFI disagrees with the
            Final Working Capital calculation it shall give written notice to
            Buyers within such ten (10) day period and, if Buyers and BFI are
            unable to resolve such disagreement within

            disagreement, they shall arbitrate such disagreement in accordance
            with the provisions of Section 13.2; and

      the Company and of Fibres in existence on the Closing Date in accordance
      with the customary payment practices of BFI. Buyers shall have the right
      to pay any trade account payable prior to its payment by BFI if Buyers
      reasonably believe that the failure to pay such account at such time would
      have an adverse effect on the future business relationship between Buyers
      and the vendor, and any amount so paid shall be deducted from the amounts
      due to BFI by Buyer pursuant to Section 1.6(c) or shall be paid by BFI to
      Buyers instead of the holder of such trade account at the time BFI pays
      such trade account, subject to BFI's reasonable satisfaction that the
      account has been paid by Buyers.

1.8   Allocation of Purchase Price. The Purchase Price shall be allocated among

            (ii)  BFI will indemnify Buyers to the extent that the Company would
                  be entitled to indemnification from the Fibres Stockholders
                  for a Fibres Environmental Indemnity Claim (1) except for the
                  fact that the claim for indemnification was not made on a

                  of the Fibres Purchase Agreement were not made "to the best of

                  the Fibres Stockholders;

            (iii) BFI will indemnify Buyers to the extent that any Fibres
                  Environmental Indemnity Claim or Fibres Remediation Loss Claim
                  which is otherwise 


                                       23
<PAGE>   29
                  payable by the Fibres Stockholders is not paid solely as a
                  result of the bankruptcy, insolvency, or similar financial
                  incapacity of the Fibres Stockholders;

            (iv)  BFI will increase the aggregate liability of the Fibres
                  Stockholders under the Fibres Purchase Agreement by and pay
                  $1,000,000 so that the aggregate liability is $7,000,000, and
                  such additional $1,000,000 may be applied either to Fibres
                  Environmental Indemnity Claims or Fibres Remediation Loss
                  Claims;

            (v)   BFI will pay any Fibres Remediation Loss Claim which the
                  Fibres Stockholders would be required to pay except for the
                  fact that the "trigger event" described in Section 1.9
                  occurred after the date set forth therein; provided that such
                  trigger event occurs prior to September 30, 2001 (or September
                  30, 2003, in the case of the Monroe Landfill).

6.4   Sole Remedy. The sole remedy of Buyer and BFI for breach of the
      representations, warranties, covenants and agreements set forth herein
      shall be pursuant to the sections in this Article 6; provided, that
      nothing in this Section 6.4 or elsewhere in this Agreement shall be deemed
      to limit any right or remedy of Buyers against Sellers for breach of the
      representations and warranties set forth in Sections 3.1, 3.2, 3.3 or 3.4,
      for breach of the Non Competition Agreement (as hereinafter defined) or
      for fraud, nor shall anything in this Section 6.4 or elsewhere in this
      Agreement be deemed to limit any right of Buyers against Sellers for
      statutory or equitable contribution with respect to liabilities not
      arising from this Agreement.

6.5   Notice of Indemnity Claim. A party seeking indemnity hereunder
      ("Indemnified Party") shall notify the other party ("Indemnifying Party")
      of its Indemnity Claim and the Indemnity Event in question within a
      reasonable time after the Indemnified Party becomes aware of the existence
      of such Indemnity Event, but in no event more than ninety (90) days;
      provided, that the failure so to timely notify shall relieve the
      Indemnifying Party from the obligation to indemnify against the liability
      respecting such Indemnity Event only to the extent the Indemnifying Party
      establishes by competent evidence that it is prejudiced thereby. Such
      Indemnity Claim must be delivered in any event prior to the expiration of
      Sellers' indemnity obligations with respect to the Indemnity Event
      relating to the Indemnity Claim as set forth in Section 6.4. In any case,
      if any such action shall be brought, and the Indemnified Party shall
      notify the Indemnifying Party of the commencement thereof, such

      have sole discretion to determine whether to contest, compromise, enter
      pleas, or settle any action brought against the Indemnified Party. If an

      request for relief other than monetary damages and such relief would be
      performed by an Indemnified Party or if the cumulative total of all

      of the portion of the Indemnity Claim in excess of the Aggregate Indemnity
      Limit or of all of such Indemnity Claim if the amount of the Indemnity

                   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

9.1   Customer Names. BFI agrees that it will not disclose the customer names

      purpose or reason whatsoever for two (2) years after the Closing Date,
      except to authorized representatives of Buyers, or as required by
      applicable law. If any Seller becomes legally compelled to disclose such

<PAGE>   33
      available remedy for such breach or threatened breach, including the
      recovery of damages.

9.2   Confidentiality.

      (a)   Buyers shall hold in confidence and not disclose to any person for
            any purpose the information received from BFI, Fibres or the

            officers, directors, employees, agents and consultants ("Buyer
            Representatives") who need to evaluate the information on their
            behalf for the purposes described herein; provided, however, that
            Buyers may disclose the information in response to any legally
            enforceable summons or subpoena or in order to comply with any
            order, law, ruling, or regulation applicable to Buyers. If any Buyer
            becomes legally compelled to disclose such confidential information,
            Buyer shall provide BFI with prompt notice of such requirement so
            that BFI may seek a protective order or other appropriate remedy.
            Each Buyer shall take all steps necessary to assure adherence by
            Buyer's Representatives to the provisions of this Agreement
            respecting the confidentiality of information. The obligation of any
            Buyer to keep information confidential shall not apply to any
            information which:

            (i)   is known to a Buyer prior to its disclosure by BFI;

            (ii)  is in general use by competitors of a Buyer;

            (iii) is or becomes part of the public domain without any breach by
                  a Buyer of any obligation of confidentiality set forth herein;
                  or

            (iv)  is communicated to a Buyer by a third party who is not bound
                  by a confidentiality agreement with BFI with respect to such
                  information.

      (b)   Upon termination of this Agreement, each Buyer will, upon request of
            BFI, return to BFI or provide evidence satisfactory to BFI that it
            has destroyed, all information received from BFI, Fibres or the
            Company in connection with the transactions contemplated by this
            Agreement.

            (i)   if any court of competent jurisdiction or other governmental
                  agency shall have issued an order, decree or ruling or taken
                  any other action permanently enjoining, restraining or
                  otherwise prohibiting the consummation of the transactions
                  contemplated hereby and such order, decree, ruling or other
                  action shall have become final and nonappealable; or

            (ii)  if the transactions contemplated hereby have not been
                  consummated on or before September 30, 1997, unless the

                  material breach of this Agreement by the party seeking to
                  terminate this Agreement.

      (c)   by Buyers if BFI breaches in any material respect any of its
            representations or warranties herein or BFI fails to perform in any
            material respect any of its covenants, agreements or obligations
            under this Agreement, and any such breach or failure is not cured

            under this Agreement, and any such breach or failure is not cured
            within thirty (30) days after written notice from BFI.

11.2  Effect of Termination. In the event of termination of this Agreement by
      either BFI or Buyers as provided in Section 11.1, this Agreement shall
      forthwith become void and have no effect, without any liability or
      obligation on the part of BFI or Buyers, other than the provisions of
      Sections 9.2, 13.5 and 13.6, and except to the extent that such
      termination 


                                       29
<PAGE>   35

                            STOCK PURCHASE AGREEMENT


        STOCK PURCHASE AGREEMENT, dated as of February 4, 1998, is entered into
by and among Waste Connections, Inc., a Delaware corporation ("WCI"), Madera
Disposal Systems, Inc., a California corporation (the "Corporation"), Alma
Sciacqua, as trustee of the Sciacqua Family Trust B, (the "Sciacqua Trust"),
Eugene Dupreau ("Dupreau"), Melvin G. Dias ("Dias"), Charles B. Youngclaus
("Youngclaus" and, collectively with the Sciacqua Trust, Dupreau and Dias, the
"Shareholders"), and Alma Sciacqua ("Alma").

        WHEREAS, the Corporation is engaged in the collection and transport of
solid waste in the City of Chowchilla and in the unincorporated areas of Madera
County, California, the operation of two transfer stations and a recycling
facility for the County of Madera, operating the Fairmead Landfill pursuant to
an operating agreement with the County of Madera, and other related activities;

        WHEREAS, the Shareholders own all of the issued and outstanding capital
stock of the Corporation in the amount set forth on Schedule 3.2 hereto (the
"Corporation's Stock") in the amount set forth on Schedule 3.2;

        WHEREAS, WCI wishes to acquire from the Shareholders all of the issued
and outstanding capital stock of the Corporation;

        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 hereinafter defined),
the Shareholders shall sell and deliver to WCI all of the issued and outstanding
Corporation's Stock, being the number of shares of the Corporation set forth on
Schedule 3.2. 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, plus
any and all additions to the Purchase Price payable pursuant to Section 1.4 (the
"Purchase Price").

        1.2    PURCHASE PRICE.  The Purchase Price shall be payable as follows:

               (a) eight million one hundred eighty five thousand dollars
        ($8,185,000), (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 


                                              1

<PAGE>   3


        Section 3.22(b)) are greater or less than the Closing Date Current
        Liabilities (as defined in Section 3.22(b)) shall be paid to the
        Shareholders at Closing in cash by wire transfer or check payable in
        clearinghouse funds. The adjustment to the Purchase Price based on the
        Closing Date Debt, the Closing Date Current Assets and the Closing Date
        Current Liabilities shall be based on estimates of such amounts provided
        at the Closing. Within 120 days after the Closing, WCI and the
        Shareholders' Representative (as hereinafter defined) shall determine
        the actual Closing Date Debt, Closing Date Current Assets and Closing
        Date Current Liabilities. If the difference between the actual amounts
        of such items and the estimated amounts provided at the Closing Date
        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 Shareholders in the same proportion as cash was paid to
        them at the Closing; if the result is a decrease in the amount that
        should have been paid at the Closing below the amount that was so paid,
        the Shareholders shall promptly pay such amount to WCI in the same
        proportion as they received cash at the Closing. Of the cash portion of
        the Purchase Price paid at the Closing, five million five hundred
        forty-five thousand dollars ($5,545,000) shall be paid to the Sciacqua
        Trust and the balance shall be paid to Dupreau, Dias and Youngclaus as
        provided in Schedule 3.2.

               (b)  At the Closing, WCI shall deliver to Dupreau, Dias and
        Youngclaus 1,000,000 shares (the "Shares") of its Common Stock, $0.01
        par value (the "WCI Stock") as follows: Dupreau-333,333 shares;
        Dias-333,334 shares; and Youngclaus- 333,333 shares.

               (c)  At the Closing, WCI shall deliver to Dupreau, Dias and
        Youngclaus warrants (the "Warrants") to purchase an aggregate of 200,000
        shares of WCI Stock, substantially in the form of Exhibit 1.2(c), with
        an exercise price of four dollars ($4.00) per share of WCI Stock as
        follows: Dupreau-Warrants for 66,667 shares; Dias-Warrants for 66,666
        shares; and Youngclaus-Warrants for 66,667 shares.

        The Shareholders acknowledge that the allocation of the Purchase Price
among the Shareholders has been agreed to by the Shareholders among themselves
as provided in Schedule 3.2. Such allocation provides that certain of the
Shareholders will receive more cash and fewer Shares and Warrants, and
conversely that certain of the Shareholders will receive more Shares and
Warrants and less cash, than would be the case if the cash, Shares and Warrants
were allocated in proportion to their ownership of the Corporation's Stock.

        1.3 ADDITIONAL CONTINGENT PURCHASE PRICE. The Purchase Price may be
increased by the additional contingent payments described in this Section.

               (a)  If, prior to the third anniversary of the date of this
        Agreement (the "Signing Date"), the Corporation enters into an exclusive
        franchise agreement to provide residential refuse collection services to
        the City of Madera for a minimum term of at least five years on terms
        satisfactory to WCI, WCI shall pay to the Procuring Shareholders (as


                                       2
<PAGE>   4

        defined below) as additional contingent Purchase Price cash in the
        amount of six hundred thousand dollars ($600,000), which amount shall be
        paid on the Closing Date if such franchise agreement is entered into on
        or prior to the Closing Date or thirty (30) days after the date such
        franchise agreement is entered into if it is entered into after the
        Closing Date.

               (b)  If, prior to the third anniversary of the Signing Date, the
        Corporation enters into exclusive franchise agreements on terms
        satisfactory to WCI with any of the municipalities of Los Banos, Kerman
        or Dos Palos, or any other municipality in Madera, Kings, Merced and
        Fresno Counties not otherwise provided for in this Agreement, WCI shall
        pay to the Procuring Shareholders as additional contingent Purchase
        Price a cash amount equal to ten percent (10%) of the projected gross
        revenue (after deduction of any franchise fee) expected to be received
        by the Corporation pursuant to such exclusive franchise agreement during
        the first year of its term, which amount shall be paid on the Closing
        Date if such franchise agreement is entered into on or prior to the
        Closing Date or thirty (30) days after the date such franchise agreement
        is entered into if it is entered into after the Closing Date.

               (c)  If, prior to the third anniversary of the Signing Date, the
        Corporation enters into an extension, on terms at least as favorable to
        the Corporation as the franchise agreement in effect on the Signing
        Date, of its existing exclusive franchise agreement with the County of
        Madera for at least seven (7) years from the present termination date of
        such agreement or an extension, on terms at least as favorable to the
        Corporation as the franchise agreement in effect on the Signing Date, of
        its existing exclusive franchise agreement with the City of Chowchilla
        for at least five (5) years from the present termination date of such
        agreement, then, in each such case, WCI shall pay the Procuring
        Shareholders as additional contingent Purchase Price a cash amount equal
        to five percent (5%) of the projected gross revenue (after deduction of
        any franchise fee) expected to be received by the Corporation pursuant
        to such exclusive franchise agreement during the first year of such
        extension, which amount shall be paid on the Closing Date if such
        extension is entered into on or prior to the Closing Date or thirty (30)
        days after the date such extension is entered into if it is entered into
        after the Closing Date.

               (d)  If, prior to the third anniversary of the Signing Date, any
        of the Shareholders provides substantial assistance to WCI or any of its
        subsidiaries in acquiring directly or indirectly (through asset
        purchase, stock purchase, merger or otherwise) the waste collection
        operations of any other company providing such services within a
        seventy-five (75) mile radius of Madera, California, including without
        limitation the waste collection operations of Turlock Scavenger and
        EMADCO, WCI shall pay the Procuring Shareholders as additional
        contingent Purchase Price a cash amount equal to three percent (3%) of
        the projected gross revenue (after deduction of any franchise fee) with
        respect to such operations during the first year after they are acquired
        by WCI, which amount shall be paid on the Closing Date if such
        acquisition is consummated on or 




                                       3
<PAGE>   5

        prior to the Closing Date or thirty (30) days after the date any such
        acquisition is consummated if consummated after the Closing Date. WCI
        shall have sole discretion in determining whether and on what terms it
        will consummate any such acquisition, and WCI shall not be liable to any
        of the Procuring Shareholders for any decision not to pursue any such
        acquisition or its failure to consummate any such acquisition, without
        regard to the reason therefor.

               (e)  If on March 1, 1999, the Corporation's franchise agreement
        with the County of Madera (or any extension described in Section 1.3(c))
        remains in effect and the County of Madera has not threatened to
        terminate or revoke such franchise agreement, the Corporation shall pay
        to Dupreau, Dias and Youngclaus, in equal shares, as additional
        contingent Purchase Price cash in the amount of two million eight
        hundred thousand dollars ($2,800,000), and upon receipt of such payment
        Dupreau, Dias and Youngclaus shall return their shares of WCI Stock and
        Warrants to WCI for cancellation. WCI's obligations under this Section
        1.3(e) shall terminate and be of no further force or effect on the
        closing date of a public offering of WCI common stock with an aggregate
        net proceeds to WCI of at least five million dollars ($5,000,000). So
        long as WCI's obligations under this Section 1.3(e) remain in effect,
        Dupreau, Dias and Youngclaus shall not dispose of any of their WCI Stock
        or Warrants. Dupreau, Dias and Youngclaus may elect, by written notice
        to WCI, to forego such payment of additional contingent Purchase Price,
        in which event they may retain their WCI Stock and Warrants.

               (f)  For purposes of this Section 1.3, a Shareholder shall be
        deemed a "Procuring Shareholder" if such Shareholder is an employee of,
        or consultant to, the Corporation or WCI at the time the event in
        question occurs.

               (g)  Subject to satisfaction of Federal and State Securities laws
        and execution by the Procuring Shareholders of such agreements
        containing such representations as counsel for WCI shall advise is
        reasonably necessary to satisfy such laws, the Procuring Shareholders
        may elect to take all or any portion of the additional contingent
        payments in shares of WCI Stock in lieu of receiving a cash payment. Any
        Procuring Shareholder electing to receive shares of WCI Stock shall
        advise WCI at least ten (10) days prior to the date any such payment is
        due pursuant to this Section of such Procuring Shareholder's intention
        to receive some or all of the additional continent payments in shares of
        WCI Stock and of the amount of such payments with respect to which such
        election is made. Subject to satisfaction of State and Federal
        Securities laws as aforesaid, WCI shall issue to such Procuring
        Shareholders on the date payment of such additional contingent payments
        are due shares of WCI Stock in a number determined by dividing the
        amount of the additional contingent payment elected to be received in
        shares of WCI Stock by the Fair Market Value of a share of WCI Stock. If
        such stock is to be delivered prior to the time that a public market for
        the WCI Stock exists, the Fair Market Value of WCI Stock shall be
        determined by the Board of Directors of WCI in good faith. If such stock
        is to be delivered at a time when a public market for WCI Stock exists,
        Fair Market Value shall 


                                       4
<PAGE>   6
        mean the average of the closing price of the WCI Stock as quoted on the
        NASDAQ Stock Market or the principal exchange on which the WCI Stock is
        listed if such stock is listed on an exchange for the ten successive
        trading days for which a closing price is quoted ending on the third
        trading day prior to the date on which such additional contingent
        payment is due. The Fair Market Value and the number of shares of WCI
        Stock to be delivered pursuant to this Section shall be appropriately
        adjusted in the event of any change in the WCI Stock between the first
        day for which a closing price is quoted in determining the Fair Market
        Value and such date, including without limitation any stock dividend,
        stock split, reverse stock split, recapitalization, reorganization,
        merger or consolidation. WCI shall not be obligated to issue any
        fractional shares of WCI Stock, but shall instead pay the Shareholder
        entitled thereto cash in lieu of any fractional share equal to the Fair
        Market Value multiplied by the fraction of a share of WCI Stock that
        would otherwise be issued.

        1.4    EXCLUDED ASSETS. The Assets of the Corporation listed on Schedule
1.4 (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 on such
date (the "Closing Date") after the consents required by Section 6.7 have been
obtained (or WCI has waived the requirement that one or more such consents be
obtained) as WCI and the Shareholders' Representative shall agree. The Closing
shall take place at the Law Offices of Shartsis, Friese & Ginsburg LLP, One
Maritime Plaza, Suite 1800, San Francisco, California 94111. At the Closing,
WCI, the Corporation and the Shareholders shall deliver to each other the
documents, instruments and other items described in Section 8 of this Agreement.
The Closing Date shall occur no earlier than February 5, 1998, but shall be
deemed effective as of February 1, 1998, for financial reporting purposes.

        3.     REPRESENTATIONS AND WARRANTIES OF THE CORPORATION,
               THE SHAREHOLDERS AND ALMA

               (b)  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.

               (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

        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 benefiting the Corporation or the Shareholders as of the
        Signing 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 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.
        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 adequate for the operation of the business of the
        Corporation and of each Corporate Property as presently operated and are
        valid and in full force and effect. All of said Collection Franchises
        and other 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.

        has the Corporation, nor party-in-interest or disqualified person,

        practices, terms and conditions of employment, wages and hours, and
        nondiscrimination in employment, and is not engaged in any unfair labor

        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 Signing Date, existing or threatened against the
        Corporation nor has the Corporation experienced any labor strike,
        slow-down, work stoppage, labor difficulty or other job action during
        the last five years. 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) will contain 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.

        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.

               (a)  The Corporation has timely filed or will timely file all
        requisite federal, state, local and other tax and information returns
        due for all fiscal periods ended on or before the date of this
        Agreement. 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 Signing Date and no
        notice of any claim for taxes has been received. Copies of (i) any tax

        federal income, and state franchise, income and sales tax returns of the
        Corporation for its last three fiscal years are attached as part 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 such Corporation) the
        Corporation has duly paid all taxes and other related charges required
        to be paid prior to the date of this Agreement. The reserves for taxes
        contained in the Financial Statements of the Corporation are adequate to
        cover its tax liability as of the date of this Agreement.

               (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

        have been paid in full.

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 such consents and approvals as are or
shall be listed on Schedule 3.19 and which will have been obtained prior to the
Closing.

        average monthly revenues derived from billings to its customers after
        the Closing Date should not continue at approximately the same rate as
        before the Signing Date.

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

relations with the Corporation.

        3.31   ABSENCE OF CERTAIN BUSINESS PRACTICES. Neither the Corporation 
nor any of the Shareholders or Alma has directly or indirectly within the past

penalty in any civil, criminal or governmental litigation or proceeding, (b) if
not given in the past, might have had an adverse effect on the financial
condition, business or results of operations of the Corporation, or (c) if not
continued in the future, might adversely affect the financial condition,
business or operations of the Corporation or which might subject the Corporation
to suit or penalty in any private or governmental litigation or proceeding.

        9.     ADDITIONAL COVENANTS OF WCI, THE CORPORATION AND THE
               SHAREHOLDERS

        9.1    NO DELAY. The Corporation, the Shareholders and WCI covenant and
agree from and after the date hereof not to hinder in any way or unreasonably
delay the Closing Date and to use their respective reasonable efforts to obtain
required Governmental Consents and otherwise to cause the Closing Date to occur
as soon as reasonably practicable after the Signing Date, provided, however,
that in using its reasonable efforts WCI shall not be required to take any
action or to agree to any condition, including without limitation any condition
imposed by any government authority with respect to the transfer of any
Governmental Permit, that, in WCI's reasonable judgment, imposes a materially
adverse financial burden or operating condition on WCI.

        9.2    RELEASE OF GUARANTIES. WCI shall use reasonable efforts to obtain
the termination and release on or prior to the Closing Date of the personal
guaranties of the Shareholders of any 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 shall cooperate with
WCI in obtaining such releases.

        9.3    RELEASE OF SECURITY INTERESTS. Between the Signing Date and 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.

        9.4    CONFIDENTIALITY. Neither the Corporation nor any of the
Shareholders shall disclose or make any public announcements of the transactions
contemplated by this Agreement 



                                       33
<PAGE>   35
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 IPO 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.

        9.5    BROKERS AND FINDERS FEES. Each party shall pay and be responsible
for any broker's, finder's or financial advisory fee incurred by such party in
connection with the transactions contemplated by this Agreement.

        9.6    TAXES. WCI shall reasonably cooperate, at the expense of the
Shareholders, with the Shareholders with respect to any matters involving the
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.

        9.7    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 each 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. 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.

        9.8    SHAREHOLDERS' REPRESENTATIVE.

                                       34
<PAGE>   36

                      (a)     In order to administer efficiently the rights and
        obligations of the Shareholders under this Agreement, the Shareholders
        hereby designate and appoint Dupreau 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 the Shareholders' Representative and the holders of a
        majority of the Corporation's Stock (including any Corporation's Stock
        held by the Shareholders' Representative), or, in the case of any
        amendment or waiver made or given or action taken after the Closing, if
        so approved 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)     Dupreau 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 



                                       35
<PAGE>   37

        substituted representative shall then be deemed to be the Shareholders'
        Representative for all purposes of this Agreement.

        9.9    CERTAIN TAX MATTERS. The Shareholders acknowledge that WCI has
indicated its intention to 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.

        10.    INDEMNIFICATION

        10.1   INDEMNITY BY THE SHAREHOLDERS. The Shareholders and Alma jointly
and severally, subject to the limitations set forth in Section 10.2, covenant
and agree that they 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 10.3(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 third anniversary of the date of filing of the
Corporation's federal and California income tax returns for the fiscal year
ending on the Closing Date or, in the case of fraud, expiration of the
applicable statute of limitations, with respect to each of the following
contingencies (all, the "10.1 Indemnity Events"):



                                       36
<PAGE>   38

               (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, provided however, as to activities of such
        predecessors, only to the extent that the Corporation or the
        Shareholders had knowledge of such activities. 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 a Corporation
        owned and/or operated such landfill does not constitute an Environmental
        Site Loss.


                                       37
<PAGE>   39

               (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. To the extent not covered by the
        Company's insurance, all matters on Schedule 3.8, Part II.

        10.2   LIMITATIONS ON SHAREHOLDERS' INDEMNITIES.

               (a)  Subject to Section 10.2(b), the obligations of the
        Shareholders to indemnify the WCI Indemnitees as provided in Section
        10.1 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
        10.1 Indemnity Events exceed $100,000 (the "Deductible Amount");
        provided, that the amount of any obligation of indemnity arising
        pursuant to Section 10.1 with respect to any representation, warranty or
        covenant contained in Sections 3.1 through 3.5, 3.18 and 3.22 hereof
        shall not be subject to the Deductible Amount.

               (b)  Absent fraud, the maximum amount which WCI can recover as a
        result of one or more 10.1 Indemnity Events pursuant to the provisions
        hereof for Claims shall not in the aggregate exceed six million dollars
        ($6,000,000) with respect to Claims made prior to the first anniversary
        of the Closing Date, five million dollars ($5,000,000) with respect to
        Claims on or after the first anniversary of the Closing Date and prior
        to the second anniversary of the Closing Date, four million dollars
        ($4,000,000) with respect to Claims made on or after the second
        anniversary of the Closing Date and prior to the third anniversary of
        the filing of the Corporation's federal and California income tax
        returns for the fiscal year ending on the date of the Closing Date, and
        thereafter nothing in the absence of fraud.

        10.3   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 10.2 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 10.3(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 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 




                                       39
<PAGE>   41

        parties to this Agreement 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 10.3 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.

        10.4   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.

        10.5   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 10.1 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.

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

        11.1   RESTRICTIVE COVENANTS. As to the Corporation, the Shareholders,
Alma and their Affiliates acknowledge that (i) WCI, as the purchaser of the
Corporation's Stock, is and will be 




                                       40

engaged in the same business as the Corporation (the "Business"); (ii) the
Shareholders, Alma and their Affiliates are intimately familiar with the
Business; (iii) the Business is currently conducted in the State of California
and WCI intends to continue the Business in California and intends, by
acquisition or otherwise, to expand the Business into other geographic areas of
California where it is not presently conducted; (iv) the Shareholders, Alma 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 11.1 are essential to protect the Business and the goodwill
being acquired; and (vi) the Shareholders, Alma 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 11 will not impair such ability. The Shareholders covenant and agree as
set forth in (a), (b) and (c) below with respect to each Corporation:

               (a)  NON-COMPETE. For a period commencing on the Closing Date and
        terminating five years thereafter (the "Restricted Period"), neither of
        the Shareholders, Alma nor any of their Affiliates shall, anywhere in
        the counties of Madera, Fresno, Stanislaus, San Joaquin, and Calaveras,
        California 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; or (iii) 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 and Alma 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 and provided further
        that Youngclaus shall be permitted to continue the business described on
        Schedule 11.1.

               (b)  CONFIDENTIAL INFORMATION. During the Restricted Period and
        thereafter, the Shareholders, Alma 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, 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 




                                       41
<PAGE>   43
        information that (i) is or becomes generally available to the public
        other than as a result of disclosure by the Shareholders and Alma 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, Alma 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, Alma 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 or Alma 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 or Alma 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 or Alma 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.

        11.2   RIGHTS AND REMEDIES UPON BREACH. If the Shareholders or Alma or
any Affiliate breaches, or threatens to commit a breach of, any of the
provisions of Section 11.1 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 



                                       42
<PAGE>   44

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 Shareholders and Alma from any violation thereof.

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

               (c)  SEVERABILITY OF COVENANTS. The Shareholders and Alma
        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 and
        Alma 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 and Alma 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.

                      (ii) by the Corporation and the Shareholders by written

any other person or entity the possible sale of all or substantially all of the
assets, business or stock of either Corporation, or to effect the merger of a
Corporation with any party other than WCI. The Shareholders and Alma hereby
confirm that no person or entity presently has or may acquire any rights to
purchase or otherwise acquire the assets or the stock of the Corporation.

the Shareholder covenant and agree that they will, jointly and severally,
indemnify and hold harmless WCI and IWCI and their respective directors,

        omission from any Exhibit, Schedule, list, certificate, or other
        instrument furnished or to be furnished to WCI or IWCI pursuant to the

        such representation or warranty or had any knowledge of any breach
        thereof.

                    (b) Any liability for Seller's or the Shareholder's
        violation or alleged violation of any state, local or federal law or

               10.3. NOTICE OF INDEMNITY CLAIM.

                     (a) In the event that any claim ("Claim") is hereafter
        asserted against or arises with respect to any Indemnitee as to which
        such Indemnitee may be entitled to indemnification hereunder, the
        Indemnitee shall notify the Seller and the Shareholder (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 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.



                                       15
<PAGE>   20

                    (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 10.2 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 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 10.3(b) and elected to defend the
        Claims, 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 30 days 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 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 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 10.3 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.

               10.4. 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 



                                       16

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.

               10.5. NO EXHAUSTION OF REMEDIES OR SUBROGATION; RIGHT OF SET OFF.
Seller and the Shareholder waive any right to require any Indemnitee to (i)
proceed against any other person or (iii) pursue any other remedy whatsoever in
the power of any Indemnitee. The Buyers may, but shall not be obligated to, set
off against any and all payments due Seller on the Note, any amount to which
WCI, IWCI or any other Indemnitee is entitled to be indemnified hereunder with
respect to any 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 Seller and the Shareholder or their successors.

                    (b) EXCEPTION TO THE NON-COMPETE. Despite the restrictions
        imposed by section 11.1(a), Buyers and Seller agree that Seller may
        continue to: (i) collect and dispose of refuse collected from containers
        owned by Bingham County pursuant to Seller's contract with Bingham
        County dated as of September 1992 (the "Bingham County Contract") until
        the Bingham County Contract expires on September 30, 1999; (ii) bid or
        negotiate for the contract to operate the Bingham County transfer
        station, if such transfer station is built within five years after the
        Closing Date, and perform under that contract if it is awarded to
        Seller; and (iii) Seller may operate the Construction and Debris
        Landfill owned by Bingham County that is currently located on Ridge
        Street in Bingham County, Idaho but that the Seller expects to be
        relocated within Bingham County shortly. These exceptions to the
        non-competition provisions of Section 11.1(a) do not allow the Seller or
        the Shareholder or any of their affiliates to: (i) collect or dispose of
        refuse from any residential or other subscription customers in Bingham
        County during the Restricted Period; (ii) renew its Bingham County
        Contract or negotiate a new contract with Bingham County after the
        Bingham County Contract expires; (iii) compete with the Buyers in
        Bingham County after September 30, 1999; or (iv) bid or negotiate for
        the right to operate the Bingham County Transfer Station or the Bingham
        County Construction and Debris Landfill if Bingham County chooses to
        bundle such services with the exclusive right to collect and transport
        solid waste in Bingham County.

                   (c) CONFIDENTIAL INFORMATION. During the Restricted Period
        and thereafter, Seller and Shareholder 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, the existence of and terms
        of this Agreement, know-how, trade secrets, customer lists, supplier
        lists, details of contracts, pricing policies, operational methods,
        marketing plans or strategies, bidding practices and policies, 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 Seller and Shareholder, or (ii)
        is general knowledge in the solid waste handling and landfill business
        and not specifically related to the Business.

                    (d) 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
        Seller or Shareholder or made available to Seller or Shareholder
        relating to the Business, but excluding any materials maintained by any



                                       18
<PAGE>   23

        attorneys for Seller or Shareholder prior to the Closing, are and shall
        be the property of WCI or IWCI and have been delivered or will be
        delivered or made available to WCI or IWCI at the Closing.

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

                    (f) NO DISPARAGEMENT. From and after the Closing Date, none
        of the Seller or the Shareholder shall, in any way to any customer or
        employee of the Business or the Buyers, denigrate or derogate Buyers 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 Seller or 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 if it adversely affects the regard or esteem
        in which such person or entity is held by such person. Without limiting
        the generality of the foregoing, none of the Seller or Shareholder
        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 customer
        or employee of the Business or the Buyers. 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.

                    (g) ACCESS TO FINANCIAL STATEMENTS. For two years from the
        Closing Date, if necessary for Buyers to obtain financing, Seller shall
        allow Buyers or Buyers' designee to audit Seller's financial statements
        and accounting records for the period of January 1, 1995 through the
        Closing Date. Buyers shall assume any costs of such audit.

                    (h) BINGHAM COUNTY CONTRACT. If Seller continues to perform 
        under the Bingham County Contract after March 31, 1999, Seller agrees to
        pay Buyers forty percent (40%) of the gross revenue that Seller bills to
        Bingham County pursuant to the Bingham County Contract until the Bingham
        County Contract terminates. Seller also agrees that Buyers may audit
        Seller's invoices to Bingham County that are associated with the Bingham
        County Contract.

               11.2. RIGHTS AND REMEDIES UPON BREACH. If Seller or Shareholder
breach, or threaten to commit a breach of, any of the provisions of Section
11.1(a), (b), (c) or (e) herein (the "Restrictive Covenants"), WCI and IWCI
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 Buyers at law or in equity:




                                       19
<PAGE>   24

                    (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 IWCI
        and that money damages would not provide an adequate remedy to IWCI.
        Accordingly, in addition to any other rights or remedies, WCI and IWCI
        shall be entitled to injunctive relief to enforce the terms of the
        Restrictive Covenants and to restrain Seller and Shareholder from any
        violation thereof.

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

                    (c) SEVERABILITY OF COVENANTS. Seller and Shareholder
        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. Buyers, Seller and
        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 Buyers, Seller and Shareholder that such determination
        not bar or in any way affect Buyers' 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.
