OVERVIEW

     We are a global leader in providing integrated waste management services.
In North America, we provide solid waste management services throughout the
United States, as well as in Canada, Mexico and Puerto Rico, including
collection, transfer, recycling and resource recovery services, and disposal
services, including the landfill disposal of hazardous wastes. In addition, we
are a leading developer, operator and owner of waste-to-energy facilities in the
United States. We also engage in other hazardous waste management services
throughout North America, as well as low-level and other radioactive waste
services. Internationally, we operate throughout Europe, the Pacific Rim, South
America and other select international markets. Our diversified customer base
includes commercial, industrial, municipal and residential customers, other
waste management companies, governmental entities and independent power markets.

RECENT DEVELOPMENTS


     On July 6, 1999, we announced that we had lowered our expected earnings per
share for the three-month period ended June 30, 1999. On July 29, 1999, we
announced a further reduction in our expected earnings for that period. On
August 3, 1999, we announced that our reported operating income for the
three-month period ended March 31, 1999 may have included certain non-recurring
pretax income items. Between July 8, 1999 and September 3, 1999, numerous
lawsuits that purport to be based on one or more of these announcements have
been filed against us and certain of our officers and directors. Taken together,
the plaintiffs of these lawsuits purport to assert claims on behalf of a class
of purchasers of our common stock between June 10, 1998 and August 2, 1999.
Among other things, the plaintiffs allege that Waste Management and certain of
its officers and directors (i) made knowingly false earnings projections for the
three months ended June 30, 1999 and (ii) failed to adequately disclose facts
relating to its earnings projections that the plaintiffs allege would have been
material to purchasers of Waste Management's common stock. The plaintiffs also
claim that certain of Waste Management's officers and directors sold common
stock at prices known to be inflated by the alleged material misstatements and
omissions. The plaintiffs in these actions seek damages with interest, costs and
such other relief as the respective courts deem proper.



     In addition, three of Waste Management's shareholders have filed lawsuits
against certain of our officers and directors in connection with the events
surrounding our second quarter 1999 earnings projections and July 6, 1999
earnings announcement. The plaintiffs in these actions purport to allege
derivative claims on behalf of Waste Management against these officers and
directors for alleged breaches of fiduciary duty resulting from their alleged
stock sales during the three-month period ended June 30, 1999 and/or their
oversight of Waste Management's affairs. The lawsuits name Waste Management,
Inc. as a nominal defendant and seek compensatory and punitive damages with
interest, equitable and/or injunctive relief, costs and such other relief as the
respective courts deem proper.



     In addition, the Commission has notified us of an informal inquiry into the
period ended June 30, 1999, as well as certain sales of our common stock that
preceded our July 6, 1999 earnings announcement.


     The New York Stock Exchange has notified us that its market Trading
Analysis Department is reviewing transactions in our common stock prior to the
July 6, 1999 earnings forecast announcement.

                                        1
<PAGE>   7

     We are conducting a thorough investigation of each of the allegations that
have been made in connection with our second quarter 1999 earnings
communications. As part of this investigation, our Board of Directors has
authorized a review of the allegations that have been made against certain of
our officers and directors. Roderick M. Hills, a former chairman of the
Commission and chairman of our audit committee, is directing the review.


     It is not possible at this time to predict the impact that the above
lawsuits may have on Waste Management Holdings or Waste Management, nor is it
possible to predict whether any other suits or claims may arise out of these
matters in the future. However, it is reasonably possible that the outcome of
any present or future litigation may have a material adverse impact on our
financial condition or results of operations in one or more future periods.
Waste Management and Waste Management Holdings intend to defend themselves
vigorously in all the above matters.



     On November 10, 1999, we announced the selection of A. Maurice Myers as our
Chairman, Chief Executive Officer and President. Mr. Myers, 59, joins us from
Yellow Corporation, where he has been Chairman, CEO and President since April
1996. Yellow Corporation is the parent company of Yellow Freight, one of the
nation's oldest and largest trucking companies. Under Mr. Myers' leadership,
Yellow Corporation returned to profitability in just one year, after three years
of negative earnings. Mr. Myers also implemented a productivity initiative and a
re-structuring of the company's largest subsidiary, Yellow Freight, dividing
that company into five regionally-based business units and reducing operating
costs, while significantly increasing the company's ability to meet changing
customer needs. Mr. Myers is a recognized leader in integrating information
technology with business operations. He directed the re-engineering of Yellow
Corporation's information systems, providing the company with greater financial
accountability and a distinct competitive advantage over other freight haulers.
In 1999, Yellow Corporation was named one of the nation's top 100 Information
Technology companies, the only freight transportation company to be so
recognized. Prior to joining Yellow Corporation in 1996, Mr. Myers served as
President and Chief Operating Officer of America West Airlines and is credited
in part for that company's financial turnaround. Mr. Myers also served as
President and CEO of Aloha Airlines, and held a senior management position with
Continental Airlines.



     On November 23, 1999 we announced the appointment of Thomas L. Smith as
Senior Vice President -- Information Systems. Mr. Smith will report to A.
Maurice Myers, and will be responsible for our information systems strategies
and implementation efforts. Mr. Smith joins us from Yellow Services, Inc., a
wholly owned subsidiary of Yellow Corporation, where he served as President.
Under Smith's leadership, Yellow Corporation was recently named as a recipient
of the 1999 CIO-100 Award by CIO Magazine for having information systems best
positioned to succeed beyond 2000.



     An Executive Committee of our Board of Directors has been formed,
consisting of A. Maurice Myers, Ralph V. Whitworth, Roderick M. Hills and Jerome
P. York. The Board of Directors has appointed Mr. Whitworth, a managing member
of Relational Investors LLC, as Chairman of the Executive Committee.



     The Board of Directors has initiated a strategic initiative aimed at
increasing shareholder value. We have engaged Chase Securities Inc. and
Donaldson, Lufkin and Jenrette Securities Corporation as financial advisors to
assist us in this matter. The plan calls for disposition of some or all of our
international assets, a substantial majority of our non-core assets, and certain
non-strategic North American solid waste assets that account for 10% of our
operating revenues in that sector. We intend immediately to initiate the
disposition of these assets, and plan to substantially complete these asset
sales in the next 12 months, although there can be no assurance that these
dispositions will be completed in the contemplated time frame. We expect to use
the proceeds of these asset dispositions as they are realized to repay debt,
repurchase shares and pursue tuck-in acquisitions.



     In the second quarter of 1999, we entered into an agreement to purchase all
of the Canadian solid waste assets of Allied Waste Industries, Inc. ("Allied")
that Allied acquired upon its acquisition of Browning-Ferris Industries, Inc.
The purchase price of these assets was to be approximately $501 million


                                        2

in cash. On November 8, 1999, we entered into revised agreements with Allied,
which replace the original agreement.



     Under the terms of the revised agreements, Allied has agreed to sell to us
all of the shares of Browning-Ferris Industries Limited ("BFIL"), which owns the
solid waste operations of Browning-Ferris in Canada, including collection
operations, transfer stations, landfill operations and recycling facilities.
Annual run rate revenues generated from these operations are approximately US
$176 million. Allied will continue to operate certain of the Canadian operations
that we are being required to divest by the Competition Bureau of Canada and
market those operations for sale, on behalf of BFIL, after the closing. The sale
of the BFIL shares is subject to final approval pursuant to the Competition Act
and the Investment Canada Act. Additionally, we have agreed to sell to Allied
certain U.S. solid waste services assets with combined reported historical
revenue of approximately $132 million, including nine landfill operations, 19
collection operations, five transfer stations and a landfill operating contract.
The sale of such assets is subject to final approval pursuant to the Hart-Scott
Rodino Act. We expect to receive net cash proceeds as a result of the revised
transactions.



     On December 15 and 16, 1999 we permanently amended our two domestic bank
credit facilities and two Euro facilities, respectively, for which waivers were
sought in the third quarter 1999. The amended terms and conditions of the
facilities also contain the necessary provisions for us to follow through with
our strategy of divesting our international and non-core assets. Initial
proceeds from the sales of such assets will be used to reduce debt and improve
our financial position.


                     SUMMARY OF TERMS OF THE EXCHANGE OFFER

     On May 21, 1999, we completed the private offering of the outstanding

     - $250 million principal amount of 7.375% Senior Notes due 2029.

     We and the guarantor executed a registration rights agreement with the
initial purchasers in the private offering of the outstanding notes in which we
and the guarantor agreed to deliver to you this prospectus and agreed to:

     - file an exchange offer registration statement with the Commission within
       120 days after May 21, 1999;

     - have the exchange offer registration statement declared effective by the
       Commission within 210 days after May 21, 1999; and

       which the exchange offer registration statement is declared effective by
       the Commission.

     You are entitled to exchange in the exchange offer your outstanding notes

     - certain contingent interest rate provisions are no longer applicable.

The Exchange Offer.........  We are offering to exchange the aggregate principal
                             amount of exchange notes for the aggregate
                             principal amount of outstanding notes. The
                             outstanding notes may be exchanged only in amounts
                             which are equal to whole multiples of $1,000.

Resales of Exchange
Notes......................  Based on Commission no action letters, we believe
                             that after the exchange offer you may offer and
                             sell the exchange notes without registration under
                             the Securities Act so long as:

                             - You acquire the exchange notes in the ordinary
                               course of business.

                             - When the exchange offer begins you do not have an
                               arrangement with another person to participate in
                               a distribution of the exchange notes.

                             - You are not engaged in a distribution of, nor do
                               you intend to distribute, the exchange notes.

                             When you tender the outstanding notes, we will ask
                             you to represent to us that:

                             - You are not an affiliate of Waste Management.

                             - You will acquire the exchange notes in the
                               ordinary course of business.

                             - When the exchange offer begins you are not
                               engaged in, nor do you have plans with another
                               person to be engaged in, a distribution of the
                               exchange notes.

                             If you are unable to make these representations,
                             you will be required to comply with the
                             registration and prospectus delivery requirements
                             under the Securities Act in connection with any
                             resale transaction.

                             If you are a broker-dealer and receive exchange
                             notes for your own account, you must acknowledge
                             that you will deliver a prospectus if you resell
                             the exchange notes. By acknowledging your intent
                             and delivering a prospectus you will not be deemed
                             to admit that you are an "underwriter" under the
                             Securities Act. You may use this prospectus as it
                             is amended from time to time when you resell
                             exchange notes which were acquired from
                             market-making or trading activities. For a year
                             after the expiration date we will make this
                             prospectus available to any broker-dealer in
                             connection with such a resale. See "Plan of
                             Distribution."

Consequences of Failure to
  Exchange Notes...........  If you do not exchange your outstanding notes
                             during the exchange offer you will no longer be
                             entitled to registration rights. You will not be
                             able to offer or sell the outstanding notes unless
                             they are later registered, sold pursuant to an
                             exemption from registration or sold in a
                             transaction not subject to the Securities Act or
                             state securities laws. Other than in connection
                             with the exchange offer, we do not currently
                             anticipate that we will register the outstanding
                             notes under the Securities Act. See "The Exchange
                             Offer -- Consequences of Failure to Exchange."

                             of Texas, National Association, the trustee. The
                             indenture, among other things, restricts our
                             ability and the ability of our subsidiaries to:

                             - create liens securing indebtedness; and

                             - engage in sale and leaseback transactions.

                             For more details, see "Description of Exchange
                             Notes -- Certain Covenants."

     The exchange notes will be freely transferable but will also be new
securities for which there will not initially be a market. Accordingly, we
cannot assure you whether a market for the exchange notes will develop or as to
the liquidity of any such market. We do not intend to apply for a listing of the
exchange notes on any securities exchange or automated dealer quotation system.
The initial purchasers in the private offering of the outstanding notes have
advised us that they intend to make a market in the exchange notes. However,
they are not required to do so, and any market-making activities with respect to
the exchange notes may be discontinued without notice.

     The Company recorded significant adjustments in the quarter ended September
30, 1999, certain of which affect account balances applicable to periods prior
to the quarter ended September 30, 1999. Accordingly, the Company, after
consultation with its independent public accountants, has concluded that its
internal controls for the preparation of interim financial information did not
provide an adequate basis for its independent public accountants to complete
reviews of the quarterly data for the quarters in the nine-month period ended
September 30, 1999. The Company believes that certain charges that were recorded
in the quarter ended September 30, 1999 may relate to individual prior periods;
however, the Company does not have sufficient information to identify all
specific charges attributable to prior periods. Based on its quantitative and
qualitative analysis of available information, the Company, after consultation
with its independent accountants, has concluded that it does not have, nor is it
able to obtain, sufficient information to conclude whether or not a material
amount of these charges relate to any prior year, although qualitative analysis
indicates that these charges are principally related to 1999. The Company has
been advised by its independent public accountants that their report on the
Company's December 31, 1999 financial statements will specifically refer to the
matters discussed above regarding the interim periods within 1999.

                                  RISK FACTORS

     In addition to the information set forth in this Prospectus, you should
carefully consider the risks described below before deciding whether to
participate in the exchange offer. The following risks include all of the risks
which we believe to be material at the current time. Additional risks not
presently known to us or that we currently deem immaterial may also impair our
business operations.

THE NOTES ARE SUBORDINATED TO THE DEBT OF OUR SUBSIDIARIES

     As a holding company, we conduct our operations through our subsidiaries.
Our only significant assets are the capital stock of our subsidiaries.
Accordingly, our ability to meet our cash obligations depends in part upon the
ability of our subsidiaries to make cash distributions to us. The ability of our
subsidiaries to make distributions to us is, and will continue to be, restricted
by, among other limitations, applicable provisions of the laws of national or
state governments and contractual provisions. Our right to participate in the
assets of any subsidiary (and thus the ability of holders of the exchange notes
to benefit indirectly from such assets) is generally subject to the prior claims
of creditors, including trade creditors, of that subsidiary, except to the
extent that we are recognized as a creditor of such subsidiary, in which case
our claims would still be subject to any security interest of other creditors of
such subsidiary. Therefore, except as described below, the exchange notes will
be subordinated by operation of law to creditors, including trade creditors, of
our subsidiaries with respect to the assets of the subsidiaries, against which
these creditors have a claim.


     The exchange notes will be guaranteed by our subsidiary Waste Management
Holdings. Our obligations under our credit facilities and our other senior
indebtedness are also currently guaranteed by Waste Management Holdings.
Similarly, we have guaranteed the outstanding senior indebtedness of Waste
Management Holdings. Thus, the exchange notes will rank equally in right of
payment with the senior indebtedness of Waste Management Holdings, the debt
under our credit facilities and our other senior indebtedness. Because of our
holding company structure and the impact of the Waste Management Holdings'
guarantee, the exchange notes will be structurally subordinated to the claims of
creditors of our subsidiaries, other than Waste Management Holdings. As of
September 30, 1999, the amount of this subsidiary indebtedness was approximately
$1.6 billion out of our total consolidated long-term debt of approximately $11.4
billion.


     Upon any release by the lenders under our credit facilities (or any
replacement or new principal credit facility) of the Waste Management Holdings'
guarantee, we and Waste Management Holdings will each be deemed automatically
and unconditionally released and discharged from our respective obligations
under the guarantees of the senior indebtedness of the other so guaranteed. In
such event, the claims of creditors of Waste Management Holdings will
effectively have priority with respect to the assets and earnings of Waste
Management Holdings over the claims of our creditors, including the holders of
the exchange notes.

U.S. BANKRUPTCY OR FRAUDULENT CONVEYANCE LAW MAY INTERFERE WITH THE PAYMENT OF
THE NOTES

     Various applicable fraudulent transfer laws allow courts, under specific
circumstances, to avoid guarantees by a subsidiary and require holders of the
guaranteed obligations to return any payments received from the subsidiary
guarantors. A court may use these laws to avoid the Waste Management Holdings
guarantee of the exchange notes in the event of bankruptcy or insolvency of
Waste Management Holdings.

     A court could set aside Waste Management Holdings' guarantee of the
exchange notes to the extent that either of the following were true at the time
it issued the guarantee:

     - Waste Management Holdings incurred the guarantee with the intent to
       hinder, delay or defraud any of its present or future creditors or
       contemplated insolvency with a design to favor one or more creditors to
       the total or partial exclusion of others; or

                                        9
<PAGE>   15

     - Waste Management Holdings did not receive fair consideration or
       reasonably equivalent value for issuing the guarantee and, at the time it
       issued the guarantee, it:

      - was insolvent or was rendered insolvent by reason of the issuance of the
        guarantee;

      - engaged or was about to engage in a business or transaction for which
        Waste Management Holdings' remaining assets constituted unreasonably
        small capital; or

      - intended to incur, or believed that it would incur, debts beyond its
        ability to pay such debts as they mature.

     Among other things, a legal challenge to Waste Management Holdings'
guarantee of the exchange notes on fraudulent transfer grounds may focus on the
benefits, if any, realized by it as a result of our issuance of the exchange
notes. To the extent Waste Management Holdings' guarantee of the exchange notes
were to be avoided on fraudulent conveyance grounds or held unenforceable for
any other reason, you would cease to have any claim in respect of Waste
Management Holdings' guarantee and would be solely our creditors. In such event,
your claim against Waste Management Holdings would be subject to the prior
payments of all Waste Management Holdings' obligations. Waste Management
Holdings may not have sufficient assets, after providing for all prior claims,
to satisfy the claims of all holders of the exchange notes relating to any
voided guarantee.

     The obligations of Waste Management Holdings under its guarantee of the
exchange notes are limited to an amount which would not cause such guarantee to
be a fraudulent transfer or conveyance. Waste Management Holdings has issued
similar guarantees of certain of our other indebtedness. The determination of
the amount that would be due under its guarantee of the exchange notes or any of
such other guarantees is uncertain.

YOU MAY NOT BE ABLE TO SELL YOUR EXCHANGE NOTES

     There is no active trading market for the exchange notes and this market
may never develop. If any of the exchange notes are traded after their initial
issuance, they may trade at a discount from their initial offering price.
Factors that could cause the exchange notes to trade at a discount are:

     - an increase in prevailing interest rates;

     - a decline in our credit worthiness;

     - a weakness in the market for similar securities; and

     - declining general economic conditions.

     Future trading prices of the exchange notes will depend on many factors,
including, among other things, prevailing interest rates, our operating results
and the market for similar securities. We do not intend to apply for a listing
of the exchange notes on any securities exchange or automated dealer quotation
system. The initial purchasers of the outstanding exchange notes have advised us
that they currently intend to make a market in the exchange notes. However, they
are not obligated to do so and any market making may be discontinued at any time
without notice.

     Historically, the market for non-investment grade debt has been subject to
disruptions that have caused volatility in prices. It is possible that the
market for the exchange notes will be subject to disruptions. Any disruptions
may have a negative effect on you, as a holder of the exchange notes, regardless
of our prospects and financial performance.


ACCOUNTING CHARGES HAVE NEGATIVELY IMPACTED REPORTED FINANCIAL RESULTS, RESULTED
IN THE IMPAIRMENT OF THE VALUE OF CERTAIN ASSETS AND MAY DECREASE OUR FUTURE
CASH FLOWS



     During the third quarter of 1999, we initiated a comprehensive review of
our accounting records, systems, processes and controls at the direction of our
Board of Directors, which was completed in November 1999. As a result of this
review, we recorded certain charges and adjustments in the quarter

                                       10
<PAGE>   16


ended September 30, 1999 totaling $1.23 billion after tax. Because of the size
of the charges, generally accepted accounting principles require us to attempt
to determine whether portions of the charges apply to prior periods. While we
believe that certain of these charges may relate to prior periods, we do not
currently have sufficient information to identify all specific charges
attributable to prior periods. Producing the information required to identify
these charges would be cost prohibitive and disruptive to our operations.



     Some of the charges and adjustments we recorded in the third quarter 1999,
such as certain increases in insurance reserves, environmental reserves, loss
contract provisions and adjustments resulting from completing account
reconciliations, are recurring in nature, and should therefore be expected to
occur in future periods. Additionally, certain of these charges and adjustments,
including receivables-related adjustments and insurance reserves, could have an
impact on our future cash flows.



     Because some of the charges discussed above affect account balances
applicable to periods prior to the quarter ended September 30, 1999, we
concluded, after consultation with our independent public accountants, that our
internal controls for the preparation of interim financial information did not
provide an adequate basis for them to complete reviews of the quarterly data for
the quarters in the nine months ended September 30, 1999. The review was
completed in November 1999, and we do not anticipate any additional material
adjustments to our financial statements based on the review. However, we may not
be able to successfully stabilize our accounting systems and procedures, and
close our accounting records and report our 1999 annual results in accordance
with yearend audit procedures. Any failure to stabilize our accounting systems
could result in additional material charges and adjustments in the future.


WE MAY ENCOUNTER DIFFICULTIES IN IMPLEMENTING OUR PROPOSED STRATEGIC INITIATIVE

     Our ability to successfully implement our proposed strategic initiative may
be affected by the willingness of prospective purchasers to purchase the assets
we identify as divestiture candidates on terms we find acceptable, the timing
and terms on which such assets may be sold, uncertainties relating to regulatory
approvals and other factors affecting the ability of prospective purchasers to
consummate such transactions. The success of our strategic initiative could also
be affected by the availability of financing, and uncertainties relating to the
impact of the proposed strategic initiative on our credit ratings and,
consequently, the availability and cost of debt and equity financing to us.

WE ARE UNDERGOING CHANGES IN MANAGEMENT


     Our business may be affected by our ability to attract and retain qualified
individuals to serve in senior management positions.


WE FACE UNCERTAINTIES RELATING TO PENDING LITIGATION AND INVESTIGATIONS

     We face uncertainties relating to pending litigation and investigations as
described in "The Company -- Recent Developments" above. We are unable to
predict the outcome or impact of these matters and there can be no assurance
that they will not have a material adverse effect on us and our business.

WE FACE POTENTIAL DIFFICULTIES IN CONTINUING TO EXPAND AND MANAGE OUR GROWTH

     We have grown rapidly, primarily through acquisitions. We cannot guarantee
that we will be able to continue to expand and successfully manage our growth.
We also cannot guarantee that our existing or acquired operations will not be
adversely affected by the pace of our growth. Improving the productivity of our
acquired operations and using our asset base and strategic position to operate
more efficiently is very important to our financial results and prospects. In
particular, whether we will ultimately achieve the

                                       11
<PAGE>   17

anticipated benefits of acquired operations will depend on a number of factors,
including our ability to effect:

     - administrative cost savings;

     - rationalization of collection routes;

     - insurance and bonding cost reductions; and

     - general economies of scale.

     Moreover, our ability to continue to grow will depend on a number of
factors, including:

     - competition from other waste management companies;

     - the availability of attractive acquisition opportunities;

     - our ability to mitigate antitrust concerns related to acquisitions in
       several markets;

     - the availability of working capital;

     - our ability to maintain margins on existing or acquired operations; and

     - our ability to manage costs in a changing regulatory environment.

OUR ACQUISITION STRATEGY INVOLVES POTENTIAL RISKS

     We regularly pursue opportunities to expand by acquiring additional waste
management businesses and operations that can be effectively integrated with our
existing operations. In addition, we regularly pursue mergers and acquisition
transactions, some of which are significant, in new markets where we believe
that we can successfully become a provider of integrated waste management
services. As one of the leading industry consolidators, we could announce
transactions with either publicly or privately owned businesses at any time.

     Our acquisition strategy involves potential risks. These risks include:

     - our failure to accurately assess all of the pre-existing liabilities of
       acquired companies;

     - unexpected difficulties in successfully integrating the operations of
       acquired companies with our existing operations;

     - a lack of attractive acquisition opportunities;

     - our inability to obtain the capital required to finance potential
       acquisitions on satisfactory terms;

     - the businesses we acquire not proving profitable; and

     - our incurring additional indebtedness or issuing additional equity
       securities as a result of future acquisitions.

WE MAY NEED ADDITIONAL CAPITAL IF OUR CASH FLOW IS LESS THAN EXPECTED


     We expect to generate sufficient cash flow from our operations to cover our
anticipated cash needs for capital expenditures and acquisitions. If our cash
flow from operations is less than currently expected, or our capital
requirements increase, either due to strategic decisions or otherwise, we may
elect to incur indebtedness or issue equity securities to cover any additional
capital needs. However, we cannot guarantee that we will be successful in
obtaining additional capital in this manner on acceptable terms.


     We also cannot guarantee that we will be successful in renewing our
existing credit facilities, or that we will be able to renew the credit
facilities on terms acceptable to us. If we are unable to renew our existing
credit facilities, or to obtain other financing sources, our business and
operating results could be affected adversely to a material extent.

                                       12
<PAGE>   18

FLUCTUATING VARIABLE INTEREST RATES COULD AFFECT US


     In the past, we have used variable rate debt under revolving bank credit
arrangements as one method of financing our rapid growth. Although our recent
financings have reduced the amount of variable rate debt as a percentage of
total indebtedness outstanding, issuing variable rate debt will continue to be
an alternative for us. Fluctuations in variable interest rates, which may occur
as general interest rates change, could have a material effect on us.


INTENSE COMPETITION COULD REDUCE OUR PROFITABILITY

     We encounter intense competition from governmental, quasi-governmental and
private sources in all aspects of our operations.

     In North America, the waste management services industry consists of large
national companies and local and regional companies of varying sizes and
financial resources. We compete with numerous waste management companies as well
as with counties and municipalities that maintain their own waste collection and
disposal operations. These counties and municipalities may have financial
competitive advantages because tax revenues and tax-exempt financing are
available to them. In addition, competitors may reduce their prices to expand
sales volume or to win competitively bid municipal contracts. Profitability may
decline because of the national emphasis on recycling, composting, and other
waste reduction programs that could reduce the volume of solid waste collected
or deposited in disposal facilities.

     Outside of North America, the waste management services industry is very
decentralized and highly fragmented. In some markets, however, we compete with
substantial companies that hold significant market shares, particularly in
Finland, Germany, the Netherlands, Sweden and the United Kingdom. Some of our
international competitors may have greater financial resources and greater
technical resources than we do with respect to specific matters. Especially in
the case of larger contracts, we may be required to commit substantial resources
over a long period of time during the proposal phase without any assurance that
the contract will be awarded to us. Examples include contracts for city-cleaning
services, contracts or bids with respect to the construction or development of
water and wastewater facilities, or permitting and development of a new
treatment facility, waste-to-energy facility, incinerator or landfill.

OUR ACCOUNTING POLICIES CONCERNING UNAMORTIZED CAPITALIZED EXPENDITURES COULD
RESULT IN A MATERIAL CHARGE AGAINST OUR EARNINGS

     In accordance with generally accepted accounting principles, we capitalize
certain expenditures and advances relating to acquisitions, pending
acquisitions, and disposal site development and expansion projects. We expense
indirect acquisition costs, such as executive salaries, general corporate
overhead, public affairs and other corporate services, as incurred. Our policy
is to charge against earnings any unamortized capitalized expenditures and
advances relating to any facility or operation that is permanently shut down,
any pending acquisition that is not consummated, and any disposal site
development or expansion project that is not completed or is no longer deemed to
be profitable within certain time frames. The charge against earnings is reduced
by any portion of the capitalized expenditure and advances that we estimate will
be recoverable, through sale or otherwise. In future periods, we may be required
to incur a charge against earnings in accordance with our policy. Depending on
its magnitude, any such charge could have a material adverse effect on our
consolidated financial statements.

GOVERNMENTAL REGULATIONS MAY RESTRICT OUR OPERATIONS OR INCREASE THE LEVEL OF
COSTS OF OUR OPERATIONS

     Stringent government regulations at the federal, state and local level in
the United States and in other countries have a substantial impact on our
operations. A large number of complex laws, rules, orders and interpretations
govern environmental protection, health and safety, land use, zoning and related
matters.

                                       13
<PAGE>   19

Among other things, they may restrict our operations and adversely affect our
operating results and financial condition by imposing conditions such as:

     - limitations on the siting and construction of new waste disposal,
       transfer or processing facilities or the expansion of existing
       facilities;

     - limitations or bans on disposal of out-of-state waste or certain
       categories of waste; or

     - mandates regarding the disposal of solid waste.

     Regulations also affect the siting, design and closure of landfills and
could require us to undertake investigatory or remedial activities, curtail
operations or close a landfill temporarily or permanently. Future changes in
these regulations may require us to modify, supplement or replace equipment or
facilities. The costs of complying with these regulations could be substantial.

     In order to develop, expand or operate a landfill or other waste management
facility, we must have various facility permits and other governmental
approvals, including those relating to zoning, environmental protection and land
use. These permits and approvals are difficult, time consuming and costly to
obtain, in part because of possible opposition by governmental officials or
citizens. In addition, these permits and approvals may contain conditions that
limit operations and our ability to change the facility or are otherwise
difficult to comply with. We cannot guarantee that we will be successful in
obtaining and maintaining in effect permits and approvals required for the
successful operation and growth of our business, including permits and approvals
for the development of additional disposal capacity needed to replace existing
capacity that is exhausted.

     Courts in the United States, basing their decisions on constitutional law,
have ruled that state and local governments may not use regulatory flow control
laws to restrict the free movement of waste in interstate commerce. We cannot
predict what impact, if any, these decisions will have on our disposal
facilities.

WE COULD BE LIABLE FOR ENVIRONMENTAL DAMAGES RESULTING FROM OUR DISPOSAL
FACILITIES AND COLLECTION OPERATIONS

     We could be liable if our disposal facilities or collection operations
cause environmental damage to our properties or to nearby landowners,
particularly as a result of the contamination of drinking water sources or soil.
Under current law, we could even be held liable for damage caused by conditions
that existed before we acquired the assets or operations involved. Also, we
could be liable if we arrange for the transportation, disposal or treatment of
hazardous substances that cause environmental contamination, or if a predecessor
owner made such arrangements and under applicable law we are treated as a
successor to the prior owner. Any substantial liability for environmental damage
could have a material adverse effect on our operating results and financial
condition.

     In the ordinary course of our business, we may become involved in a variety
of legal and administrative proceedings relating to land use and environmental
laws and regulations. These may include proceedings in which:

     - agencies of federal, state, local or foreign governments seek to impose
       liability on us under applicable statutes, sometimes involving civil or
       criminal penalties for violations, or to revoke or deny renewal of a
       permit we need; and

     - citizen groups, adjacent landowners or governmental agencies oppose the
       issuance of a permit or approval we need, allege violations of the
       permits under which we operate or laws or regulations to which we are
       subject, or seek to impose liability on us for environmental damage for
       which we may be responsible.

     The adverse outcome of one or more of these proceedings could have a
material adverse effect on our financial position, results of operations or cash
flows.

                                       14
<PAGE>   20

     From time to time we have received citations or notices from governmental
authorities that our operations are not in compliance with our permits or
certain applicable environmental or land use laws and regulations. In the future
we may receive additional citations or notices. We generally seek to work with
the authorities to resolve the issues raised by such citations or notices.
However, we cannot guarantee that we will always be successful in this regard.
Where we are not, we may incur fines, penalties or other sanctions that could
have a material adverse effect on our financial position, results of operations
or cash flows.

     Our insurance for environmental liability meets or exceeds statutory
requirements. However, because we believe that the cost for such insurance is
high relative to the coverage it would provide, our coverages are generally
maintained at statutorily required levels. Due to the limited nature of such
insurance coverage for environmental liability, if we were to incur liability
for environmental damage, such liability could have a material adverse effect on
our financial position, results of operations or cash flows.

THE DEVELOPMENT AND ACCEPTANCE OF ALTERNATIVES TO LANDFILL DISPOSAL AND
WASTE-TO-ENERGY FACILITIES COULD REDUCE OUR ABILITY TO OPERATE AT FULL CAPACITY

     Our customers are increasingly using alternatives to landfill disposal,
such as recycling and composting. In addition, state and local governments are
increasingly mandating recycling and waste reduction at the source and
prohibiting the disposal of certain types of wastes, such as yard wastes, at
landfills or waste-to-energy facilities. These developments could reduce the
volume of waste going to landfills and waste-to-energy facilities in certain
areas, which may affect our ability to operate our landfills and waste-to-energy
facilities at full capacity as well as the prices that we can charge for
landfill disposal and waste-to-energy services.

FLUCTUATIONS IN THE PRICE OF RECYCLABLE MATERIALS AFFECT OUR OPERATING REVENUES

     Recyclable materials that we process for sale, including paper, plastics,
aluminum and other commodities, are subject to significant price fluctuations.
These fluctuations will affect our future operating revenues and income.

THE COMMISSION IS INVESTIGATING THE ACCOUNTING PRACTICES OF WASTE MANAGEMENT
HOLDINGS

     The Commission has commenced a formal investigation with respect to the
previously filed financial statements (which were subsequently restated) and the
related accounting policies, procedures and system of internal controls of Waste
Management Holdings, Inc., or "WM Holdings," which we acquired through a merger
in July 1998. Several lawsuits and claims have been filed against WM Holdings
and some of its former officers and directors in connection with the restatement
of WM Holdings' financial statements. We are unable to predict the outcome or
impact of the investigation or any previously filed or future lawsuits or claims
arising out of the restatement. However, it is reasonably possible that they
could have a material adverse impact on our financial condition or results of
operations in one or more future periods.

OUR INTERNATIONAL OPERATIONS ENCOUNTER SOCIAL, POLITICAL AND ECONOMIC RISKS

     Our operations in foreign countries generally are subject to a number of
risks inherent in any business operating in foreign countries, all of which are
beyond our control. These risks include:

     - political, social and economic instability;

     - inflation;

     - general strikes;

     - nationalization of assets;

     - currency restrictions and exchange rate fluctuations;

     - nullification, modification or renegotiation of contracts; and

     - governmental regulation.

                                       15
<PAGE>   21

     We can make no prediction as to how existing or future foreign governmental
regulations in any jurisdiction may affect us in particular or the waste
management industry in general.

OUR BUSINESS IS SEASONAL IN NATURE AND OUR REVENUES AND RESULTS VARY FROM
QUARTER TO QUARTER

     Our operating revenues are usually lower in the winter months, primarily
because the volume of waste relating to construction and demolition activities
usually increases in the spring and summer months and the volume of industrial
and residential waste in certain regions where we operate usually decreases
during the winter months. Our first and fourth quarter results of operations
typically reflect lower operating revenues as a result of this seasonality.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     In the normal course of our business, we, in an effort to help keep our
stockholders and the public informed about our operations, may from time to time
issue or make certain statements, either in writing or orally, that are or
contain forward-looking statements, as that term is defined in the U.S. federal
securities laws. Generally, these statements relate to business plans or
strategies, projected or anticipated benefits or other consequences of such
plans or strategies, projected or anticipated benefits from acquisitions made by
or to be made by us, or projections involving anticipated revenues, earnings, or
other aspects of operating results. Certain statements contained in this
prospectus under "Prospectus Summary -- The Company -- Recent Developments" and
in the reports and filings with the Commission that we incorporated by reference
may be forward-looking statements. The words "may," "expect," "believe,"
"anticipate," "project," "estimate," their opposites and similar expressions are
intended to identify forward-looking statements. We caution readers that such
statements are not guarantees of future performance or events and are subject to
a number of factors that may tend to influence the accuracy of the statements
and the projections upon which the statements are based, including but not
limited to those discussed above under "Risk Factors." All phases of our
operations are subject to a number of uncertainties, risks, and other
influences, many of which are outside our control, and any one of which, or a
combination of which, could materially affect our consolidated financial
statements and operations and whether forward-looking statements made by us
ultimately prove to be accurate.

     These factors are discussed more completely in our filings with the
Commission, including our annual report on Form 10-K for the year ended December
31, 1998, and our quarterly reports on Form 10-Q for the quarters ended March
31, 1999 and June 30, 1999, which are incorporated by reference into this
prospectus.

                                USE OF PROCEEDS

     There will be no net proceeds payable to us from the issuance of the
exchange notes. The net proceeds of approximately $1.1 billion from the sale of
the outstanding notes were used to repay all outstanding indebtedness under our
syndicated credit facility and to reduce outstanding commercial paper.

(1) Earnings were insufficient to fund fixed charges in 1997. Additional
    earnings of $660.4 million were necessary to cover fixed charges for this
    period. The earnings available for fixed charges were negatively impacted by
    merger costs of $112.7 million (primarily related to the United Waste
    Systems, Inc. merger in August 1997), and asset impairments and unusual
    items of $1.8 billion. The asset impairment and unusual items of $1.8
    billion primarily related to a comprehensive review performed by Waste
    Management Holdings of its operating assets and investments.

(2) Earnings were insufficient to fund fixed charges in 1998. Additional
    earnings of $720.4 million were necessary to cover fixed charges for this
    period. The earnings available for fixed charges were negatively impacted by
    merger costs of $1.8 billion and asset impairments and unusual items of
    $864.1 million related primarily to the mergers between Waste Management,
    Inc. and Waste Management Holdings in July 1998, and Waste Management, Inc.
    and Eastern Environmental Services, Inc. in December 1998.


(3) Earnings were insufficient to fund fixed charges for the nine months ended
    September 30, 1999. Additional earnings of $155.0 million were necessary to
    cover fixed charges for this period. The earnings available for fixed
    charges were negatively impacted by merger costs of $111.3 million related
    to the merger between Waste Management, Inc. and Waste Management Holdings,
    Inc. in July 1998 and $700.0 million related to the comprehensive review we
    performed of our operating assets and investments.



     We computed our consolidated ratios of earnings to fixed charges by
dividing earnings available for fixed charges by fixed charges. For this
purpose, earnings available for fixed charges are the sum of income available
for fixed charges before income taxes, undistributed earnings from affiliated
companies' minority interests, cumulative effect of accounting changes, and
fixed charges, excluding capitalized interest. Fixed charges are interest,
whether expensed or capitalized, amortization of debt expense and discount on
premium relating to indebtedness, and such portion of rental expense that can be
demonstrated to be representative of the interest factor in the particular case.

                       DESCRIPTION OF THE EXCHANGE NOTES

     The following description is a summary of the material provisions of the
Senior Indenture and the Registration Rights Agreement. It does not restate
those agreements in their entirety. We urge you to read the Senior Indenture and
the Registration Rights Agreement because they, and not this description, define
your rights as holders of the Exchange Notes.

     Capitalized terms used in this description, but not otherwise defined in
this description or other sections of this Prospectus, have the meanings
ascribed to them in the Senior Indenture and the Registration Rights Agreement,
as applicable, unless the context otherwise requires. For purposes of this
"Description of the Exchange Notes," the term "Senior Securities" means
collectively the outstanding notes (the "Notes"), the exchange notes (the
"Exchange Notes"), and all other senior debt securities of the Company issued
under the Senior Indenture. In this description, the words "we," "our," and the
"Company" refer only to Waste Management, Inc., but not to any of our
subsidiaries, unless the context otherwise requires.

     We will issue the Exchange Notes as four series of Senior Securities under
an Indenture (the "Senior Indenture") dated as of September 10, 1997 between the
Company and Chase Bank of Texas, National Association, as trustee (the
"Trustee"). The terms of the Notes and the Exchange Notes include those stated
in the Senior Indenture and those made part of the Senior Indenture by reference
to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

     Anyone who receives this Prospectus may obtain a copy of the Senior
Indenture and Registration Rights Agreement without charge by writing to Waste
Management, Inc., 1001 Fannin Street, Suite 4000, Houston, Texas 77002,
Attention: Secretary.

GENERAL

     The Exchange Notes:

     - will be our general unsecured senior obligations;

     - will rank equally with all of our other senior and unsecured obligations,
       including debt under our credit facilities; and

     - will be unconditionally guaranteed by our subsidiary Waste Management
       Holdings (the "Subsidiary Guarantor").

     We will issue the Exchange Notes under the Senior Indenture; the Exchange
Notes will rank pari passu as to the right of payment of principal and any
premium and interest with each other series issued thereunder and will rank
senior to all series of subordinated securities issued and outstanding and that
may be issued from time to time. The Exchange Notes will be our unsecured senior
obligations. The Senior Indenture does not limit the amount of Senior
Securities, debentures, notes or other types of indebtedness that may be issued
by us or any of our subsidiaries nor does it restrict transactions between us
and our affiliates or the payment of dividends or other distributions by us to
our stockholders. The rights of our creditors, including holders of the Exchange
Notes, will be limited to our assets and the Exchange Notes will not be an
obligation of any of our subsidiaries (other than pursuant to the Subsidiary
Guarantee). In addition, the Senior Indenture does not and the Exchange Notes
will not contain any covenants or other provisions that are intended to afford
holders of the Exchange Notes special protection in the event of either a change
of control of the Company or a highly leveraged transaction by us.

     The Subsidiary Guarantee of the Exchange Notes:

     - will be a general, unsecured obligation of the Subsidiary Guarantor; and

     - will rank equally in right of payment with all existing and future senior
       and unsecured indebtedness of the Subsidiary Guarantor.

                                       18
<PAGE>   24

     We conduct our operations through our subsidiaries. Our operating
subsidiaries will not guarantee the Exchange Notes. (The Subsidiary Guarantor is
not an operating subsidiary.) Thus, in the event of a bankruptcy, liquidation or
reorganization of any of these non-guarantor subsidiaries, it will pay the
holders of its debts and its trade creditors before it will be able to
distribute any of its assets to us.

     We will issue the Exchange Notes in the form of one or more Global Exchange
Notes, in registered form, without coupons, in denominations of $1,000 or an
integral multiple thereof as described under "-- Book-Entry; Delivery; Form and
Transfer." The Global Exchange Notes will be registered in the name of a nominee
of DTC. Each Global Exchange Note (and any Exchange Note issued in exchange
therefor) will be subject to certain restrictions on transfer set forth therein
as described under "-- Book-Entry; Delivery; Form and Transfer -- Transfers of
Interests in Global Exchange Notes for Certificated Exchange Notes." Except as
set forth herein under "-- Book-Entry; Delivery; Form and Transfer -- Transfers
of Interests in Global Exchange Notes for Certificated Exchange Notes," owners
of beneficial interests in a Global Exchange Note will not be entitled to have
Exchange Notes registered in their names, will not receive or be entitled to
receive physical delivery of any such Exchange Note and will not be considered
the registered holder thereof under the Senior Indenture.

PRINCIPAL, MATURITY AND INTEREST

     We will issue the Exchange Notes as four series with an aggregate principal
amount of $1,150,000,000. The 2001 Exchange Notes will have an aggregate
principal amount of $200,000,000, the 2004 Exchange Notes will have an aggregate
principal amount of $200,000,000, the 2009 Exchange Notes will have an aggregate
principal amount of $500,000,000 and the 2029 Exchange Notes will have an
aggregate principal amount of $250,000,000. We will issue the Exchange Notes
only in fully registered form, without coupons, in denominations of $1,000 and
integral multiples of $1,000 in excess thereof. There is no sinking fund
applicable to the Exchange Notes.

     The 2001 Exchange Notes will mature on May 15, 2001, the 2004 Exchange
Notes will mature on May 15, 2004, the 2009 Exchange Notes will mature on May
15, 2009, and the 2029 Exchange Notes will mature on May 15, 2029.

     The Exchange Notes will bear interest at the respective rates per year set
forth on the front cover of this Prospectus. Interest on all Exchange Notes will
be payable semi-annually in arrears on May 15 and November 15 of each year until
maturity, commencing on November 15, 1999. The Company will make each interest
payment to the persons in whose name the Exchange Notes are registered at the
close of business on the April 30 and October 31 immediately preceding the
relevant interest payment date. Interest on the Exchange Notes will accrue from
and including the date of original issuance, or if interest has already been
paid, from and including the date it was most recently paid to (but not
including) each interest payment date. Interest will be computed on the basis of
a 360-day year comprised of twelve 30-day months.

     We, the Subsidiary Guarantor and the Initial Purchasers entered into a
Registration Rights Agreement dated as of May 21, 1999 pursuant to which we and
the Subsidiary Guarantor agreed to use our best efforts to conduct an exchange
offer to exchange the Notes for Exchange Notes registered under the Securities
Act or have a shelf registration statement (the "Shelf Registration Statement")
declared effective with respect to the Notes. See "-- Registration Rights;
Liquidated Damages." Upon the issuance of the Exchange Notes, if any, or the
effectiveness of a Shelf Registration Statement, the Senior Indenture with
respect to the Notes and the Subsidiary Guarantee will be subject to and
governed by the Trust Indenture Act.

METHODS OF RECEIVING PAYMENTS ON THE EXCHANGE NOTES

     If a holder has given wire transfer instructions to us, we will pay all
principal, interest, and premium, if any, on those Exchange Notes in accordance
with those instructions. All other payments on Exchange
                                       19
<PAGE>   25

Notes will be made at the office or agency of the Paying Agent and Registrar
within the City and State of New York unless we elect to make interest payments
by check mailed to the holders at their addresses set forth in the register of
holders.

REPLACEMENT OF SECURITIES

     We will replace any mutilated Exchange Note at the expense of the holder
upon surrender of such Exchange Note to the Trustee. We will replace Exchange
Notes that become destroyed, stolen or lost at the expense of the holder upon
delivery to the Trustee of evidence of destruction, loss or theft thereof
satisfactory to us and the Trustee. In the case of a destroyed, lost or stolen
Exchange Note, an indemnity satisfactory to the Trustee and to us may be
required at the expense of the holder of such Exchange Note before a replacement
Exchange Note will be issued. (Section 306 of the Senior Indenture)

PAYING AGENT FOR THE NOTES

     Payment of principal of and any premium and interest on the Exchange Notes
will be made at the office of the Paying Agent or Paying Agents, as we may
designate from time to time, except that at our option, payment of any interest
may be made by check mailed on or before the due date to the address of the
Person entitled thereto as such address shall appear in the Security Register.
(Sections 307, 1002 of the Senior Indenture) We may at any time rescind the
designation of any Paying Agent or approve a change in the office through which
any Paying Agent acts, except that we will be required to maintain a Paying
Agent in each Place of Payment for the Exchange Notes. Payment of any
installment of interest on an Exchange Note will be made to the Person in whose
name such Exchange Note is registered at the close of business on the Regular
Record Date for such interest. (Section 307 of the Senior Indenture)

     All monies paid by us to a Paying Agent for the payment of principal of and
any premium or interest on any Exchange Note which remain unclaimed at the end
of two years after such principal, premium or interest shall have become due and
payable will (subject to applicable escheat laws) be repaid to us and the holder
of such Exchange Note will thereafter look only to us for payment thereof.
(Section 1003 of the Senior Indenture)

TRANSFER AND EXCHANGE

     A holder may transfer or exchange the Exchange Notes in accordance with the
Senior Indenture. The Registrar and the Trustee may require a holder, among
other things, to furnish appropriate endorsements and transfer documents and we
may require a holder to pay any taxes and fees required by law or permitted by
the Senior Indenture. We are not required to transfer or exchange any Exchange
Note for a period of 15 days before a selection of Exchange Notes to be
redeemed. See -- "Optional Redemption."

     The registered holder of an Exchange Note will be treated as the owner of
it for all purposes.

SUBSIDIARY GUARANTEE

     The Subsidiary Guarantor will guarantee our obligations under the Exchange
Notes. However, the obligations of the Subsidiary Guarantor under its guarantee
of the Exchange Notes are limited to an amount which would not cause the
Subsidiary Guarantor's guarantee of the Exchange Notes to be a fraudulent
transfer or conveyance. The Subsidiary Guarantee will constitute a general,
unsecured obligation of the Subsidiary Guarantor and will rank equally in right
of payment with all existing and future senior and unsecured indebtedness of the
Subsidiary Guarantor. See "Risk Factors -- U.S. bankruptcy or fraudulent
conveyance law may interfere with the payment of the notes."

                                       20
<PAGE>   26

     The Subsidiary Guarantee will be released:

     (1) upon our consolidation or merger with or into the Subsidiary Guarantor;

     (2) upon payment in full of all principal, premium, if any, and interest on
         the Exchange Notes; or

     (3) upon the release of the Subsidiary Guarantor's guarantees under our
         credit facilities (or any replacement or new principal credit
         facility).

RANKING

     As a holding company, we conduct our operations through our subsidiaries.
Our only significant assets are the capital stock of our subsidiaries.
Accordingly, our ability to meet our cash obligations depends in part upon the
ability of our subsidiaries to make cash distributions to us. The ability of our
subsidiaries to make distributions to us is, and will continue to be, restricted
by, among other limitations, applicable provisions of the laws of national or
state governments and contractual provisions. Our right to participate in the
assets of any subsidiary (and thus the ability of holders of the Exchange Notes
to benefit indirectly from such assets) is generally subject to the prior claims
of creditors, including trade creditors, of that subsidiary, except to the
extent that we are recognized as a creditor of such subsidiary, in which case
our claims would still be subject to any security interest of other creditors of
such subsidiary. Therefore, except as described below, the Exchange Notes will
be subordinated by operation of law to creditors, including trade creditors, of
our subsidiaries with respect to the assets of the subsidiaries, against which
these creditors have a claim.


     The Exchange Notes will be guaranteed by our subsidiary Waste Management
Holdings. Our obligations under our credit facilities and our other senior
indebtedness are currently guaranteed by Waste Management Holdings. Similarly,
we have guaranteed the outstanding senior indebtedness of Waste Management
Holdings. Thus, the Exchange Notes will rank equally in right of payment with
the senior indebtedness of Waste Management Holdings, the debt under our credit
facilities and our other senior indebtedness. Because of our holding company
structure and the impact of the Waste Management Holdings' guarantee, the
Exchange Notes will be structurally subordinated to the claims of creditors of
our subsidiaries, other than Waste Management Holdings. As of September 30,
1999, the amount of this subsidiary indebtedness was approximately $1.6 billion
out of our total consolidated long-term debt of approximately $11.4 billion.


     Upon any release by the lenders under our credit facilities (or any
replacement or new principal credit facility) of the Waste Management Holdings'
guarantee, we and Waste Management Holdings will each be deemed automatically
and unconditionally released and discharged from our respective obligations
under the guarantees of the senior indebtedness of the other so guaranteed. In
such event, the claims of creditors of Waste Management Holdings will
effectively have priority with respect to the assets and earnings of Waste
Management Holdings over the claims of our creditors, including the holders of
the Exchange Notes.

OPTIONAL REDEMPTION

     The 2001 Exchange Notes will not be redeemable. The 2004, 2009 and 2029
Exchange Notes will be redeemable at our option at any time and from time to
time, in whole or in part, upon not less than 30 nor more than 60 days notice to
each holder of Exchange Notes, at a redemption price equal to the Make-Whole
Price. "Make-Whole Price" means an amount equal to the greater of (1) 100% of
the principal amount of the Exchange Notes to be redeemed and (2) as determined
by an Independent Investment Banker, the sum of the present values of the
remaining scheduled payments of principal and interest thereon (not including
any portion of such payments of interest accrued as of the date of redemption)
discounted to the date of redemption on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in
each case, accrued and unpaid interest thereon to the date of redemption. Unless
we default in payment of the redemption price, on and after the date of
redemption, interest will cease to accrue on the Exchange Notes or portions
thereof called for redemption.

                                       21
<PAGE>   27

     "Adjusted Treasury Rate" means, with respect to any date of redemption, the
rate per annum equal to the semi-annual yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such date of redemption, plus 0.125% for the 2004 Exchange Notes, 0.25% for the
2009 Exchange Notes and 0.30% for the 2029 Exchange Notes.

     "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to
the remaining term of the Exchange Notes to be redeemed that would be utilized,
at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the Exchange Notes.

     "Comparable Treasury Price" means, with respect to any date of redemption,
(1) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day preceding such date of redemption, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities," or (2) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the average
of the Reference Treasury Dealer Quotations for such date of redemption, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Trustee obtains fewer than three such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer Quotations.

     "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Trustee after consultation with us.

     "Reference Treasury Dealer" means each of Donaldson, Lufkin & Jenrette
Securities Corporation; Banc of America Securities LLC, Chase Securities, Inc.,
J.P. Morgan & Co., Credit Suisse First Boston, Deutsche Bank Securities, Inc.
and Salomon Smith Barney Inc., and their respective successors; but if any of
the foregoing shall not be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer"), we shall substitute therefor another
Primary Treasury Dealer.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any date of redemption, the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day preceding such date of redemption.

     We may purchase the Exchange Notes in the open market, by tender or
otherwise. The Exchange Notes so purchased may be held, resold or surrendered to
the Trustee for cancellation. If applicable, we will comply with the
requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and other securities laws and regulations in connection
with any such purchase. The Exchange Notes may be defeased in the manner
provided in the Senior Indenture.

Indenture compounded semi-annually, in either case, of the obligation of a

period for which such lease has been extended or may, at the option of the
lessor, be extended); the net amount of rent required to be paid for any such
period shall be the total amount of the rent payable by the lessee with respect
to such period, but may exclude amounts required to be paid on account of

<PAGE>   28

upon the payment of a penalty, such net amount shall also include the amount of
such penalty, but no rent shall be considered as required to be paid under such
lease subsequent to the first date upon which it may be so terminated.

     "Consolidated Net Tangible Assets" shall mean, at any date of

course of collection), or guarantees the payment of dividends or other
distributions upon the shares of any other Person. The amount of the obligor's
obligation under any Guaranty shall (subject to any limitation set forth

guaranteed.

property or fixture which secures payment or performance of an obligation and
shall include any mortgage, lien, encumbrance, charge or other security interest

judicial process or otherwise.

     Consolidation, Merger, Sale. The Senior Indenture provides that we may not
consolidate with or merge into any other Person or convey, transfer or lease its
properties and assets substantially as an entirety to any Person, unless

          (a) the Person formed by such consolidation or into which we are
     merged or the Person which acquires by conveyance or transfer, or which
     leases, our properties and assets substantially as an entirety shall be a
     corporation, partnership or trust which shall expressly assume, by a
     supplemental indenture, executed and delivered to the Trustee, in form
     satisfactory to the Trustee, the due and punctual payment of the principal
     of and any premium and interest (including all additional amounts, if any,

     any indebtedness which becomes our obligation or the obligation of a
     Subsidiary as a result of such transaction as having been incurred by us or
     such Subsidiary at the time of such transaction, no Event of Default, and
     no event which, after notice or lapse of time or both, would become an
     Event of Default, shall have happened and be continuing.

     Upon our consolidation with, or merger into, any other Person or any
conveyance, transfer or lease of our properties and assets substantially as an
entirety, the successor Person formed by such consolidation or into which we are
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of ours, under
the Senior Indenture with the same effect as if such successor Person had been
named as herein, and thereafter, except in the case of a lease, the predecessor
Person shall be relieved of all obligations and covenants under the Senior
Indenture and the Senior Securities, and may liquidate and dissolve. (Sections
801, 802 of the Senior Indenture)

     Limitation on Liens. The Senior Indenture provides that:

          (a) We will not, and will not permit any of our Restricted
     Subsidiaries to, create, incur, assume or suffer to exist, directly or
     indirectly, any Indebtedness secured by a Security Interest upon any of our
     Principal Property or of any of our Restricted Subsidiaries, whether owned
     as of the date of the Senior Indenture or thereafter acquired subsequent to
     the date of the Senior Indenture, without making effective provision (and
     we hereby covenant that in any such case we shall make or cause to be made
     effective provision) whereby the Senior Securities of that series then
     outstanding and any of our other Indebtedness or the other Indebtedness of
     any of our Restricted Subsidiaries then entitled thereto shall be secured
     by such Security Interest equally and ratably with any and all of our other

     thereby secured for so long as any of our such other Indebtedness or such
     other Indebtedness of any of our Restricted Subsidiaries shall be so
     secured; but nothing in the Senior Indenture shall prevent, restrict or
     apply to Indebtedness secured by:

        created prior to or contemporaneously with, or within 360 days after,

        of construction, development or improvement thereof; or

                (b) any Security Interest upon property or assets existing at
        the time of its acquisition, which Security Interest secures obligations
        assumed by the us or any of our Restricted Subsidiaries; or

        agreement with respect to any property or assets acquired by us or any
        of our Restricted Subsidiaries, or

        shares of stock of a corporation or firm at the time such corporation or
        firm is merged into or consolidated with us or any of our Restricted
        Subsidiaries or at the time of a sale, lease or other disposition of the
        property or assets of such corporation or firm as an entirety or

        shares of stock of any successor to us in accordance with the provisions
        of the covenant described in "-- Consolidation, Merger, Sale";

        if, in each case, any such Security Interest described in the foregoing
        clauses (b), (c), (d) or (e) does not attach to or affect property or
        assets owned by us or any of our Restricted Subsidiaries before the
        event referred to in such clauses; or

        being contested in good faith; or

             (3) Any Security Interest arising by reason of deposits with, or
        the giving of any form of security to, any governmental agency or any
        body created or approved by law or governmental regulation, which is
        required by law or governmental regulation as a condition to the
        transaction of any business or the exercise of any privilege, franchise
        or license (including, without limitation, any Security Interest arising
        by reason of one or more letters of credit in connection with any
        international waste management contract to be performed by us or by any
        of our Subsidiaries or their respective affiliates); or

        us or any of our Restricted Subsidiaries to conduct business, to
        maintain self-insurance, or to obtain the benefit of, or comply with,
        laws; or

                                       25
<PAGE>   31

             (9) Any Security Interest that secures any Indebtedness of a
        Restricted Subsidiary owing to us or another of our Restricted
        Subsidiaries or by us to a Restricted Subsidiary; or

             (10) Any Security Interest incurred in connection with pollution
        control, sewage or solid waste disposal, industrial revenue or similar

        qualified as current assets in accordance with United States generally
        accepted accounting principles entered into by us or by any of our
        Restricted Subsidiaries, if such program is on terms comparable for
        similar transactions, or any document executed by us or by any of our
        Restricted Subsidiaries in connection therewith, and if such Security
        Interest is limited to the trade or other receivables in respect of
        which such program is created or exists and the proceeds thereof; or

             (12) Any extension, renewal or refunding (or successive extensions,
        renewals or refundings) in whole or in part of any Indebtedness secured
        by any Security Interest referred to in the foregoing clauses (1)
        through (11), inclusive, but the Security Interest securing such
        Indebtedness shall be limited to the property or assets which,
        immediately before such extension, renewal or refunding, secured such
        Indebtedness and additions to such property or assets.

             Notwithstanding the foregoing provisions, we and any of our
        Restricted Subsidiaries may create, incur, assume or suffer to exist any
        Indebtedness secured by a Security Interest without so securing the
        Notes if, at the time such Security Interest becomes a Security Interest
        upon any of our Principal Property or the Principal Property of any such
        Restricted Subsidiary and after giving effect thereto, the aggregate
        outstanding principal amount of all our Indebtedness and the

        Interests permitted by this sentence (excluding Indebtedness secured by
        a Security Interest existing as of the date of the Senior Indenture, but
        including the Attributable Debt in respect of Sale and Leaseback
        Transactions, other than Sale and Leaseback Transactions which, if the
        Attributable Debt in respect thereof had been Indebtedness secured by a
        Security Interest, would have been permitted by clause (1)(a) above,
        other Sale and Leaseback Transactions the proceeds of which have been
        applied or committed to be applied in accordance with the covenant
        described in "-- Limitations on Sale and Leaseback Transactions" and
        other than Sale and Leaseback Transactions between us and any of our
        Restricted Subsidiaries) does not exceed 15% of Consolidated Net
        Tangible Assets. (Section 1008 of the Senior Indenture)

          (b) If, upon any consolidation or merger of any Restricted Subsidiary
     with or into any other corporation, or upon any consolidation or merger of
     any other corporation with or into us or any of our Restricted Subsidiaries
     or upon any sale or conveyance of the Principal Property of any Restricted
     Subsidiary as an entirety or substantially as an entirety to any other
     Person, or upon any acquisition by us or by any of our Restricted
     Subsidiaries by purchase or otherwise of all or any part of the Principal
     Property of any other Person, any Principal Property theretofore owned by
     us or such Restricted Subsidiary would thereupon become subject to any
     Security Interest not permitted by the terms of the foregoing covenant, we,
     before such consolidation, merger, sale or conveyance, or acquisition,
     will, or will cause such Restricted Subsidiary to, secure payment of the
     principal of and interest, if any, on the Exchange Notes (equally and
     ratably with or prior to any of our other Indebtedness or the other
     Indebtedness of such Restricted Subsidiary then entitled thereto) by a
     direct lien on all such Principal Property prior to all liens other than
     any liens theretofore existing thereon by a supplemental indenture or
     otherwise. (Section 1008 of the Senior Indenture)

     Limitations on Sale and Leaseback Transactions. The Senior Indenture
provides that:

     We will not, and will not permit a Restricted Subsidiary to, enter into any
arrangement with any Person (other than with any Restricted Subsidiary)
providing for the leasing to us or any Restricted Subsidiary of any Principal
Property owned or hereafter acquired by us or such Restricted Subsidiary (except
for temporary leases for a term, including any renewal thereof, of not more than
three years and
                                       26
<PAGE>   32

except for leases between us and a Restricted Subsidiary or between Restricted
Subsidiaries), which Principal Property has been or is to be sold or transferred
by us or such Restricted Subsidiary to such person (a "Sale and Leaseback
Transaction") unless

          (a) we or such Restricted Subsidiary would be entitled, pursuant to
     the covenant described in "-- Limitation on Liens," to incur Indebtedness
     secured by a Security Interest on the property to be leased without equally
     and ratably securing the Exchange Notes, or

          (b) we shall, and in any such case we covenant that we will, within
     180 days after the effective date of any such arrangement, apply an amount
     equal to the fair value (as determined by our Board of Directors) of such
     property to the redemption of Senior Securities that, by their terms, are
     subject to redemption, or to the purchase and retirement of Senior
     Securities, or to the payment or other retirement of funded debt for money
     borrowed, incurred or assumed by us which ranks senior to or equally and
     ratably with the Exchange Notes or of funded debt for money borrowed,
     incurred or assumed by any Restricted Subsidiary (other than, in either
     case, funded debt owed by us or any Restricted Subsidiary), or

          (c) we shall within 180 days after entering into the Sale and
     Leaseback Transaction, enter into a bona fide commitment or commitments to
     expend for the acquisition or capital improvement of a Principal Property
     an amount at least equal to the fair value (as determined by our Board of
     Directors) of such property. (Section 1009 of the Senior Indenture)

     Notwithstanding the foregoing, we may, and may permit any Restricted
Subsidiary to, effect any Sale and Leaseback Transaction that is not acceptable
pursuant to clauses (a)through (c), inclusive, of the foregoing covenant, if the
Attributable Debt associated with such Sale and Leaseback Transaction, together
with the aggregate principal amount of outstanding debt secured by Security
Interests upon Principal Property not acceptable pursuant to clauses (1) through
(12) of the covenant described in "-- Limitation on Liens," inclusive, do not
exceed 15% of Consolidated Net Tangible Assets. (Section 1009 of the Senior
Indenture)

     Compliance Certificates. We are required to furnish to the Trustee annually
a statement as to our compliance with all conditions and covenants under the
Senior Indenture. (Section 1006 of the Senior Indenture)

EVENTS OF DEFAULT; REMEDIES

     Events of Default. An Event of Default with respect to any given series of
the Exchange Notes is defined under the Senior Indenture as being one or more of
the following events (hereinafter in this "Description of the Exchange Notes,"
the term "Notes" or "Note" shall mean the "Exchange Note(s)" unless the context
otherwise requires):

          (1) default in the payment of any interest upon any Note of that
     series when it becomes due and payable, and continuance of such default for
     a period of 30 days; or

          (2) default in the payment of the principal of (or premium, if any,
     on) any Note of that series as and when the same becomes due and payable
     whether at maturity, by declaration of acceleration, call for redemption or
     otherwise; or

          (3) default in the performance, or breach, of any of our other
     covenants or warranties in the Senior Indenture (other than a covenant or
     warranty a default in whose performance or whose breach is elsewhere in
     Section 501 of the Senior Indenture specifically dealt with or which has
     expressly been included in the Senior Indenture solely for the benefit of a
     series of Senior Securities other than the Notes), and continuance of such
     default or breach for a period of 60 days after there has been given, by
     registered or certified mail, to us by the Trustee or to us and the Trustee
     by the holders of at least 25% in principal amount of the Notes of that
     series a written notice specifying such default or breach and requiring it
     to be remedied and stating that such notice is a "Notice of Default" under
     the Senior Indenture; or
                                       27
<PAGE>   33

          (4) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in our respect in an involuntary case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or (B) a decree or order adjudging us a
     bankrupt or insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in our respect
     under any applicable Federal or State law, or appointing a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or other similar
     official of ours or of any substantial part of our property, or ordering
     the winding up or liquidation of our affairs, and the continuance of any
     such decree or order for relief or any such other decree or order unstayed
     and in effect for a period of 90 consecutive days; or

          (5) our commencement of a voluntary case or proceeding under any
     applicable Federal or State bankruptcy, insolvency, reorganization or other
     similar law or of any other case or proceeding to be adjudicated a bankrupt
     or insolvent, or our consent to the entry of a decree or order for relief
     in our respect in an involuntary case or proceeding under any applicable
     Federal or State bankruptcy, insolvency, reorganization or other similar
     law or the commencement of any bankruptcy or insolvency case or proceeding
     against us, or our filing of a petition or answer or consent seeking
     reorganization or relief under any applicable Federal or State law, or our
     consent to the filing of such petition or to the appointment of or taking
     possession by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or similar official of ours or of any substantial part of our
     property, or our making of an assignment for the benefit of creditors, or
     our admission in writing of our inability to pay our debts generally as
     they become due, or our taking of corporate action in furtherance of any
     such action. (Section 501 of the Senior Indenture)

     Remedies. If an Event of Default with respect to any given series of Notes
at the time outstanding occurs and is continuing, then in every such case,
either the Trustee or the holders of not less than 25% in principal amount of
the outstanding Notes of that series may declare the principal amount to be due
and payable immediately, by a notice in writing to us (and to the Trustee if
given by holders), and upon any such declaration such principal amount shall
become immediately due and payable. At any time after such a declaration of
acceleration with respect to the Notes of any given series has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee, the holders of a majority in principal amount of the outstanding
Notes of that series, by written notice to us and the Trustee, may rescind and
annul such declaration and its consequences if:

          (1) we have paid or deposited with the Trustee a sum sufficient to
     pay:

             (A) all overdue interest on all Notes of that series,

             (B) the principal of (and premium, if any, on) any Note of that
        series which has become due otherwise than by such declaration of
        acceleration and any interest thereon at the rate prescribed therefor,

             (C) to the extent that payment of such interest is lawful, interest
        upon overdue interest at the rate prescribed therefor, and

             (D) all sums paid or advanced by the Trustee and the reasonable
        compensation, expenses, disbursements and advances of the Trustee, its
        agents and counsel, and

          (2) all Events of Default with respect to Notes of that series, other
     than the non-payment of the principal of Notes of that series which have
     become due solely by such declaration of acceleration, have been cured or
     waived as provided in the Senior Indenture.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon. (Section 502 of the Senior Indenture) If the Trustee or any
holder of a Note of a given series has instituted any proceeding to enforce any
right or remedy under the Senior Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such holder, then and in every such case, subject to any
determination in such proceeding, we, the Trustee

                                       28
<PAGE>   34

and the holders of Notes of that series shall be restored severally and
respectively to their former positions under the Senior Indenture and the Notes
of that series, and thereafter all rights and remedies of the Trustee and the
holders shall continue as though no such proceeding had been instituted.
(Section 509 of the Senior Indenture)

     The Senior Indenture provides that, subject to the duty of the Trustee
during default to act with the required standard of care, the Trustee is under
no obligation to exercise any of its rights or powers under the Senior Indenture
at the request or direction of any of the holders, unless such holders shall
have offered to the Trustee reasonable indemnity. (Sections 601, 603 of the
Senior Indenture) No holder of any Note of a given series shall have any right
to institute any proceeding, judicial or otherwise, with respect to the Senior
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy thereunder, unless:

          (1) such holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Notes of that series;

          (2) the holders of not less than 25% in principal amount of the
     outstanding Notes of that series shall have made written request to the
     Trustee to institute proceedings in respect of such Event of Default in its
     own name as Trustee under the Senior Indenture;

          (3) such holder or holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the holders of a majority in
     principal amount of the outstanding Notes of that series. (Section 507 of
     the Senior Indenture)

     Notwithstanding any other provision in the Senior Indenture, the right of
any holder of any Note to receive payment of the principal of and any premium
and any interest on such Note on the Stated Maturity or Maturities (each as
defined in the Senior Indenture) expressed in such Note, or to institute suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such holder. (Sections 508,
902 of the Senior Indenture)

     The holders of a majority in principal amount of the outstanding Notes of
any given series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Notes of that
series, provided that (1) such direction shall not be in conflict with any rule
of law or with the Senior Indenture; (2) the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction; and
(3) the Trustee shall not be obligated to take any action unduly prejudicial to
holders not joining in such direction or involving the Trustee in personal
liability. (Section 512 of the Senior Indenture) The holders of a majority in
principal amount of the outstanding Notes of any given series may on behalf of
the holders of all the Notes of that series waive any past default under the
Senior Indenture with respect to the Notes of that series and its consequences,
except a default in the payment of the principal of or any premium or interest
on any Note of that series or in respect of a covenant or provision of the
Senior Indenture which, pursuant to the Senior Indenture, cannot be modified or
amended without the consent of the holder of each outstanding Note of that
series. Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of the Senior Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon. (Sections
513, 902 of the Senior Indenture)

     If a default occurs under the Senior Indenture with respect to the Notes of
any given series, the Trustee shall give the holders of Notes of that series
notice of such default as and to the extent provided by the Trust Indenture Act;
but in the case of any default or breach of certain covenants or warranties
                                       29
<PAGE>   35

with respect to the Notes of any given series, no such notice to holders shall
be given until at least 30 days after the occurrence thereof (the term "default"
for purposes of these provisions being defined as any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to the Notes of that series). (Section 602 of the Senior Indenture)

     To the fullest extent allowed under applicable law, if for the purpose of
obtaining judgment against us in any court it is necessary to convert the sum
due in respect of the principal of, or premium, if any, or interest on, any
Notes (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in the City of New York the Required Currency with the Judgment Currency on the
business day in the City of New York next preceding that on which final judgment
is given. Neither we nor the Trustee shall be liable for any shortfall nor shall
either of them benefit from any windfall in payments to holders of Notes under
this provision of the Senior Indenture caused by a change in exchange rates
between the time the amount of a judgment against us is calculated as above and
the time the Trustee converts the Judgment Currency into the Required Currency
to make payments under the foregoing provisions of the Senior Indenture to
holders of Notes, but payment of such judgment shall discharge all amounts owed
by us on the claim or claims underlying such judgment. (Section 506 of the
Senior Indenture)

DISCHARGE OF INDENTURE

     Satisfaction and Discharge of Indenture. The Senior Indenture provides that
we may at our option at any time, satisfy and discharge the Senior Indenture
(except as to any surviving rights of registration of transfer or exchange of
Senior Securities and any right to receive additional amounts pursuant to the
Senior Indenture) with respect to all Senior Securities issued under the Senior
Indenture, which Senior Securities have not already been delivered to the
Trustee for cancellation and which either have become due and payable or are by
their terms due and payable within one year (or are to be called for redemption
within one year) by depositing with the Trustee as trust funds an amount
sufficient to pay when due the principal (and premium, if any) and any interest
on all outstanding Senior Securities when due. (Section 401 of the Senior
Indenture)

     Defeasance and Discharge. The Senior Indenture provides that, if we so
elect by Board Resolution with respect to the Notes of any given series, we will
be discharged from any and all obligations in respect of the Notes of that
series (except for certain obligations relating to temporary Notes and exchange
of Notes, registration of transfer or exchange of Notes, replacement of stolen,
lost or mutilated Notes, maintenance of paying agencies to hold moneys for
payment in trust and payment of additional amounts, if any, required in
consequence of United States withholding taxes imposed on payments to non-United
States persons or otherwise required by Section 1004 of the Senior Indenture)
upon the deposit with the Trustee, in trust, of money and/or U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of (and premium, if any), and each installment
of interest on, the Notes of that series on the stated maturity of such payments
in accordance with the terms of the Senior Indenture and the Notes of that
series. (Sections 1302, 1304 of the Senior Indenture) Such a trust may only be
established if, among other things, we have delivered to the Trustee an opinion
of counsel to the effect that (i) we have received from, or there has been
published by, the Internal Revenue Service a ruling, or (ii) since the date of
the Senior Indenture there has been a change in applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of
counsel shall confirm that, the holders of such series will not recognize
income, gain or loss for federal income tax purposes as a result of such
deposit, defeasance and discharge, and will be subject to federal income tax on
the same amounts and in the same manner and at the same times as would have been
the case if such deposit, defeasance and discharge had not occurred. (Section
1304 of the Senior Indenture)

     Covenant Defeasance. The Senior Indenture also provides that, if we so
elect by Board Resolution with respect to the Notes of any given series, we may
omit to comply with certain restrictive covenants, including the covenants
described under "-- Limitation on Liens" and "-- Limitations on Sale and
                                       30
<PAGE>   36

Leaseback Transactions," and any such omission shall not be an Event of Default
with respect to the Notes of that series, upon the deposit with the Trustee, in
trust, of money and/or U.S. Government Obligations which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of (and premium, if
any), and each installment of interest on, the Notes of that series on the
stated maturity of such payments in accordance with the terms of the Senior
Indenture and the Notes of that series. Our obligations under the Senior
Indenture and the Notes of that series other than with respect to such covenants
shall remain in full force and effect. (Section 1303 of the Senior Indenture)
Such a trust may be established only if, among other things, we have delivered
to the Trustee an opinion of counsel to the effect that the holders of such
series will not recognize income, gain or loss for federal income tax purposes
as a result of such deposit and defeasance of certain obligations and will be
subject to federal income tax on the same amounts and in the same manner and at
the same time as would have been the case if such deposit and defeasance had not
occurred. (Section 1304 of the Senior Indenture)

     Although the amount of money and U.S. Government Obligations on deposit
with the Trustee would be intended to be sufficient to pay amounts due on the
Notes of such series at the time of their stated maturity, in the event we
exercise our option to omit compliance with the covenants defeased with respect
to the Notes as described above, and the Notes are declared due and payable
because of the occurrence of any Event of Default, such amount may not be
sufficient to pay amounts due on the Notes at the time of the acceleration
resulting from such Event of Default. We shall in any event remain liable for
such payments as provided in the Senior Indenture.

     Federal Income Tax Consequences. Under current United States federal income
tax law, defeasance and discharge would likely be treated as a taxable exchange
of the Notes to be defeased for an interest in the defeasance trust. As a
consequence, a holder would recognize gain or loss equal to the difference
between the holder's cost or other tax basis for the Notes and the value of the
holder's interest in the defeasance trust, and thereafter would be required to
include in income the holder's share of the income, gain or loss of the
defeasance trust. Under current United States federal income tax law, covenant
defeasance would ordinarily not be treated as a taxable exchange of the Notes.

MEETINGS, MODIFICATION AND WAIVER

     We and the Trustee may make modifications and amendments of the Senior
Indenture with the consent of the holders of a majority in aggregate principal
amount of the Outstanding Senior Securities of each series affected by such
modification or amendment; but no such modification or amendment may, without
the consent of the holder of each Outstanding Senior Security affected thereby,

          (a) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on any Senior Security,

          (b) change the Redemption Date with respect to any Senior Security,

          (c) reduce the principal amount of, or premium or interest on, any
     Senior Security,

          (g) impair the right to institute suit for the enforcement of any
     payment on or with respect to any Senior Security,

          (h) reduce the percentage in principal amount of outstanding Senior
     Securities of any series, the consent of whose holders is required for
     modification or amendment of the Senior Indenture or for waiver of
     compliance with certain provisions of the Senior Indenture or for waiver of
     certain defaults,

          (i) reduce the requirements contained in the Senior Indenture for
     quorum or voting,
                                       31
<PAGE>   37

          (j) change any of our obligations to maintain an office or agency in
     the places and for the purposes required by the Senior Indenture, or

          (k) modify any of the above provisions. (Section 902 of the Senior
     Indenture)

     We may make modifications and amendments of the Senior Indenture without
the consent of any holders of Senior Securities, when authorized by a Board
Resolution, and the Trustee, to:

          (a) evidence the succession of another Person and the assumption by
     any such successor of our covenants therein and in the Senior Securities
     pursuant to Article Eight of the Senior Indenture; or

          (b) add to our covenants for the benefit of the holders of all or any
     series of Senior Securities (and if such covenants are to be for the
     benefit of less than all series of Senior Securities, stating that such
     covenants are expressly being included solely for the benefit of such
     series) or to surrender any right or power therein conferred upon us; or

          (c) add any additional Events of Default; or

          (d) permit or facilitate the issuance of Senior Securities in
     uncertificated form, provided that any such action shall not adversely
     affect the interests of the holders of Senior Securities of any series in
     any material respect; or

          (e) add to, change or eliminate any of the provisions of the Senior
     Indenture in respect of one or more series of Senior Securities, but any
     such addition, change or elimination (A) shall neither (i) apply to any
     Senior Security of any series created before the execution of such
     supplemental indenture and entitled to the benefit of such provision nor
     (ii) modify the rights of the holder of any such Senior Security with
     respect to such provision or (B) shall become effective only when there is
     no such Senior Security Outstanding; or

          (f) secure the Senior Securities pursuant to the requirements of
     Section 1006 of the Senior Indenture or otherwise; or

          (g) establish the form or terms of Senior Securities of any series as
     permitted by Sections 201 and 301 of the Senior Indenture; or

          (h) evidence and provide for the acceptance of appointment under the
     Senior Indenture by a successor Trustee with respect to the Senior
     Securities of one or more series and to add to or change any of the
     provisions of the Senior Indenture as shall be necessary to provide for or
     facilitate the administration of the trusts thereunder by more than one
     Trustee, pursuant to the requirements of Section 611(b) of the Senior
     Indenture; or

          (i) cure any ambiguity, to correct or supplement any provision therein
     or in any supplemental indenture which may be defective or inconsistent
     with any other provision therein or in any supplemental indenture, or to
     make any other provisions with respect to matters or questions arising
     under the Senior Indenture; but such action shall not adversely affect the
     interests of the holders of Senior Securities of any series in any material
     respect. (Section 901 of the Senior Indenture)

     The holders of a majority in aggregate principal amount of outstanding
Notes of any given series may, on behalf of all holders of Notes of that series
outstanding, waive, insofar as the Notes of that series are concerned,
compliance by us with certain restrictive provisions of the Senior Indenture.
(Section 1007 of the Senior Indenture) The holders of a majority in aggregate
principal amount of the Notes of a series may, on behalf of all holders of Notes
of that series, waive any past default under the Senior Indenture with respect
to the Notes of that series, except a default (a) in the payment of the
principal of or any premium or interest on the Notes of that series or (b) in
respect of a covenant or provision of the Senior Indenture which cannot be
modified or amended without the consent of the holder of each outstanding Note
of that series. (Section 513 of the Senior Indenture)

                                       32
<PAGE>   38

     The Senior Indenture contains provisions for convening meetings of the
holders of Notes of any given series. (Section 1402) A meeting may be called at
any time by the Trustee, and also, upon our request, or the holders of at least
10% in aggregate principal amount of the outstanding Notes of any given series,
in any such case upon notice given in accordance with "Notices" below. (Section
1402 of the Senior Indenture) Except for any consent which must be given by the
holder of each outstanding Note of any given series, as described above, any
resolution presented at a meeting (or adjourned meeting at which a quorum is
present) may be adopted by the affirmative vote of the holders of a majority in
aggregate principal amount of the Notes of that series; but any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which may be made, given or taken by the holders of a
specified percentage, which is less than a majority, in aggregate principal
amount of the Notes of any given series may be adopted at a meeting (or
adjourned meeting duly reconvened at which a quorum is present) by the
affirmative vote of the holders of such specified percentage in aggregate
principal amount of the Notes of that series. Any resolution passed or decision
taken at any meeting of holders of Notes of any given series duly held in
accordance with the Senior Indenture will be binding on all the holders of the
Notes of that series. The quorum at any meeting of the holders of Notes of any
given series, and at any reconvened meeting, will be Persons holding or
representing a majority in aggregate principal amount of the Notes of that
series. (Section 1404 of the Senior Indenture)

     Governing Law. The Senior Indenture, the Notes and the Exchange Notes will
be governed by, and construed in accordance with, the laws of the State of New
York. (Section 113 of the Senior Indenture)

NOTICES

     We will give notices to holders of the Notes by first-class mail to the
addresses of such holders as they appear in the Security Register. (Section 106
of the Senior Indenture)

REGARDING THE TRUSTEE

     The Trustee appointed and serving as trustee pursuant to the Senior
Indenture is Chase Bank of Texas, National Association ("Chase Bank").

     The Senior Indenture contains certain limitations on the right of the
Trustee, should it become our creditor, to obtain payment of claims in certain
cases, or to realize for its own account on certain property received in respect
of any such claim as security or otherwise. (Section 613 of the Senior
Indenture) The Trustee is permitted to engage in certain other transactions.
Chase Bank, as the trustee under the Senior Indenture, may be a depository for
funds of, may make loans to and may perform other routine banking services for
us and certain of our affiliates in the normal course of business. Chase Bank
also serves as trustee for our subordinated debentures. If the Trustee acquires
any conflicting interest (as described in the Senior Indenture), it must
eliminate such conflict or resign within 90 days of the occurrence and the
continuance of a default under the Senior Indenture. (Section 608 of the Senior
Indenture)

     The holders of a majority in principal amount of all outstanding Notes of
any given series (or if more than one series of Senior Securities is affected
thereby, all series of Senior Securities so affected, voting as a single class)
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy or power available to the Trustee for the
Notes of that series or all such series of Senior Securities so affected.
(Section 512 of the Senior Indenture)

     In case an Event of Default with respect to the Notes of any given series
shall occur (and shall not be cured) under the Senior Indenture and is known to
the Trustee, the Trustee shall exercise such of the rights and powers vested in
it by the Senior Indenture and use the same degree of care and skill in its
exercise as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs. Subject to such provisions, no Trustee will be
under any obligation to exercise any of its rights or powers under the Senior
Indenture at the request of any of the holders of the Notes of any given series
unless they shall have offered to the Trustee security and indemnity
satisfactory to it.

BOOK-ENTRY, DELIVERY; FORM AND TRANSFER

     We will initially issue the Exchange Notes in the form of one or more
registered global Exchange Notes without interest coupons (collectively the
"Global Exchange Notes"). Upon issuance, the Global Exchange Notes will be
deposited with the Trustee, as custodian for DTC, and registered in the name of
DTC or its nominee, in each case for credit to the accounts of DTC's Direct and
Indirect Participants (as defined below).

     The Global Exchange Notes may be transferred, in whole and not in part,
only to another nominee of DTC or to a successor of DTC or its nominee in
certain limited circumstances. Beneficial interests in the Global Exchange Notes
may be exchanged for Exchange Notes in certificated form in certain limited
circumstances. See "-- Transfer of Interests in Global Exchange Notes for
Certificated Exchange Notes."

DEPOSITARY PROCEDURES

     DTC has advised us that DTC is a limited-purpose trust company created to
hold securities for its participating organizations (collectively, the "Direct
Participants") and to facilitate the clearance and settlement of transactions in
those securities between Direct Participants through electronic book-entry
changes in accounts of Participants. The Direct Participants include securities
brokers and dealers (including the Initial Purchasers), banks, trust companies,
clearing corporations and certain other organizations. Access to DTC's system is
also available to other entities that clear through or maintain a direct or
indirect, custodial relationship with a Direct Participant (collectively, the
"Indirect Participants"). DTC may hold securities beneficially owned by other
persons only through the Direct Participants or Indirect Participants, and such
other persons' ownership interest and transfer of ownership interest will be
recorded only on the records of the appropriate Direct Participant and/or
Indirect Participant, and not on the records maintained by DTC.

     DTC has also advised us that, pursuant to DTC's procedures, (1) upon
deposit of the Global Exchange Notes, DTC will credit the accounts of the Direct
Participants designated by the Initial Purchasers with portions of the principal
amount of the Global Exchange Notes allocated by the Initial Purchasers to such
Direct Participants, and (2) DTC will maintain records of the ownership
interests of such Direct Participants in the Global Exchange Notes and the
transfer of ownership interests by and between Direct Participants. DTC will not
maintain records of the ownership interests of, or the transfer of ownership
interests by and between, Indirect Participants or other owners of beneficial
interests in the Global Exchange Notes. Direct Participants and Indirect
Participants must maintain their own records of the ownership interests of, and
the transfer of ownership interests by and between, Indirect Participants and
other owners of beneficial interests in the Global Exchange Notes.

     The laws of some states require that certain persons take physical delivery
in definitive, certificated form, of securities that they own. This may limit or
curtail the ability to transfer beneficial interests in a Global Exchange Note
to such persons. Because DTC can act only on behalf of Direct Participants,
which in turn act on behalf of Indirect Participants and others, the ability of
a person having a beneficial interest in a Global Exchange Note to pledge such
interest to persons or entities that are not Direct Participants in DTC, or to
otherwise take actions in respect of such interests, may be affected by the lack
of physical certificates evidencing such interests. For certain other
restrictions on the transferability of the Exchange Notes see "-- Transfers of
Interests in Global Exchange Notes for Certificated Exchange Notes."

     EXCEPT AS DESCRIBED IN "-- TRANSFERS OF INTERESTS IN GLOBAL EXCHANGE NOTES
FOR CERTIFICATED EXCHANGE NOTES," OWNERS OF BENEFICIAL INTERESTS IN THE GLOBAL
EXCHANGE NOTES WILL NOT HAVE EXCHANGE NOTES REGISTERED IN THEIR NAMES, WILL NOT
RECEIVE PHYSICAL DELIVERY OF EXCHANGE NOTES IN CERTIFICATED FORM AND WILL NOT BE
CONSIDERED THE REGISTERED OWNERS OR HOLDERS THEREOF UNDER THE SENIOR INDENTURE
FOR ANY PURPOSE.

     Under the terms of the Senior Indenture, we and the Trustee will treat the
persons in whose names the Exchange Notes are registered (including Exchange
Notes represented by Global Exchange Notes) as

                                       34
<PAGE>   40

the owners thereof for the purpose of receiving payments and for any and all
other purposes whatsoever. Payments in respect of the principal, premium,
Liquidated Damages, if any, and interest on Global Exchange Notes registered in
the name of DTC or its nominee will be payable by the Trustee to DTC or its
nominee as the registered holder under the Senior Indenture. Consequently,
neither we, the Trustee nor any of our agents or the Trustee has or will have
any responsibility or liability for (1) any aspect of DTC's records or any
Direct Participant's or Indirect Participant's records relating to or payments
made on account of beneficial ownership interests in the Global Exchange Notes
or for maintaining, supervising or reviewing any of DTC's records or any Direct
Participant's or Indirect Participant's records relating to the beneficial
ownership interests in any Global Exchange Note or (2) any other matter relating
to the actions and practices of DTC or any of its Direct Participants or
Indirect Participants.

     DTC has advised us that its current payment practice (for payments of
principal, interest and the like) with respect to securities such as the
Exchange Notes is to credit the accounts of the relevant Direct Participants
with such payment on the payment date in amounts proportionate to such Direct
Participant's respective ownership interests in the Global Exchange Notes as
shown on DTC's records. Payments by Direct Participants and Indirect
Participants to the beneficial owners of the Exchange Notes will be governed by
standing instructions and customary practices between them and will not be the
responsibility of DTC, the Trustee or us. Neither we nor the Trustee will be
liable for any delay by DTC or its Direct Participants or Indirect Participants
in identifying the beneficial owners of the Exchange Notes, and we and the
Trustee may conclusively rely on and will be protected in relying on
instructions from DTC or its nominee as the registered owner of the Exchange
Notes for all purposes.

     The Global Exchange Notes will trade in DTC's Same-day Funds Settlement
System and, therefore, transfers between Direct Participants in DTC will be
effected in accordance with DTC's procedures, and will be settled in immediately
available funds. Transfers between Indirect Participants who hold an interest
through a Direct Participant will be effected in accordance with the procedures
of such Direct Participant but generally will settle in immediately available
funds.

     DTC has advised us that it will take any action permitted to be taken by a
holder of Exchange Notes only at the direction of one or more Direct
Participants to whose account interests in the Global Exchange Notes are
credited and only in respect of such portion of the aggregate principal amount
of the Exchange Notes as to which such Direct Participant or Direct Participants
has or have given direction. However, if there is an Event of Default with
respect to the Exchange Notes, DTC reserves the right to exchange Global
Exchange Notes (without the direction of one or more of its Direct Participants)
for legended Exchange Notes in certificated form, and to distribute such
certificated forms of Exchange Notes to its Direct Participants. See
"-- Transfers of Interests in Global Exchange Notes for Certificated Exchange
Notes."

     Although DTC has agreed to the foregoing procedures to facilitate transfers
of interests in Global Exchange Notes among Direct Participants, it is under no
obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. None of the Initial Purchasers or
the Trustee will have any responsibility for the performance by DTC or its
respective Direct and Indirect Participants of their respective obligations
under the rules and procedures governing any of their operations.

     The information in this section concerning DTC and its book-entry system
has been obtained from sources that we believe to be reliable, but we do not
take any responsibility for the accuracy thereof.

TRANSFERS OF INTERESTS IN GLOBAL EXCHANGE NOTES FOR CERTIFICATED EXCHANGE NOTES

     We may exchange an entire Global Exchange Note for Certificated Exchange
Notes if (1) (a) DTC notifies us that it is unwilling or unable to continue as
Depositary for the Global Exchange Notes or we determine that DTC is unable to
act as such Depositary and we thereupon fail to appoint a successor depositary
within 90 days or (b) DTC has ceased to be a clearing agency registered under
the Exchange Act, (2) we at our option, notify the Trustee in writing that we
elect to cause the issuance of Certificated Exchange Notes or (3) there shall
have occurred and be continuing a Default or an Event of Default with
                                       35
<PAGE>   41

respect to the Exchange Notes. In any such case, we will notify the Trustee in
writing that, upon surrender by the Direct and Indirect Participants of their
interest in such Global Exchange Note, Certificated Exchange Notes will be
issued to each person that such Direct and Indirect Participants and the DTC
identify as being the beneficial owner of the related Exchange Notes.

     Beneficial interests in Global Exchange Notes held by any Direct or
Indirect Participant may be exchanged for Certificated Exchange Notes upon
request to DTC, by such Direct Participant (for itself or on behalf of an
Indirect Participant), to the Trustee in accordance with customary DTC
procedures. Certificated Exchange Notes delivered in exchange for any beneficial
interest in any Global Exchange Note will be registered in the names, and issued
in any approved denominations, requested by DTC on behalf of such Direct or
Indirect Participants (in accordance with DTC's customary procedures).

     Neither we nor the Trustee will be liable for any delay by the holder of
the Global Exchange Notes or DTC in identifying the beneficial owners of
Exchange Notes, and we and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the holder of the Global Exchange
Note or DTC for all purposes.

CERTIFICATED EXCHANGE NOTES

     Certificated Exchange Notes may be exchangeable for other Certificated
Exchange Notes of any authorized denominations and of a like aggregate principal
amount and tenor in accordance with the Senior Indenture. Certificated Exchange
Notes may be presented for exchange, and may be presented for registration of
transfer (duly endorsed, or accompanied by a duly executed written instrument of
transfer), at the designated office of the Trustee (the "Security Registrar").
Such transfer or exchange will be effected upon the Security Registrar or such
other transfer agent, as the case may be, being satisfied with the documents of
title and identity of the person making the request. We may at any time
designate additional transfer agents with respect to the Exchange Notes.

     We shall not be required to (a) issue, exchange or register the transfer of
any Certificated Exchange Note for a period of 15 days next preceding the
mailing of notice of redemption of such Exchange Note or (b) exchange or
register the transfer of any Certificated Exchange Note or portion thereof
selected, called or being called for redemption, except in the case of any
Certificated Exchange Note to be redeemed in part, the portion thereof not so to
be redeemed.

     If a Certificated Exchange Note is mutilated, destroyed, lost or stolen, it
may be replaced at the office of the Security Registrar upon payment by the
holder of such expenses as may be incurred by us and the Security Registrar in
connection therewith and the furnishing of such evidence and indemnity as we and
the Security Registrar may require. Mutilated Exchange Notes must be surrendered
before new Exchange Notes will be issued.

SAME DAY SETTLEMENT

     Payments in respect of the Exchange Notes represented by the Global
Exchange Notes (including principal, premium, if any, and interest and
Liquidated Damages, if any) will be made by wire transfer of immediately
available same day funds to the accounts specified by the holder of interests in
such Global Exchange Note. Principal, premium, if any, and interest and
Liquidated Damages, if any, on all Certificated Exchange Notes in registered
form will be payable at the office or agency of the Trustee, except that, at our
option, payment of any interest and Liquidated Damages, if any, may be made (1)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the security register or (2) by wire transfer to an account
maintained by the Person entitled thereto as specified in the security register.

                               THE EXCHANGE OFFER

     We sold the Notes on May 21, 1999, pursuant to the Purchase Agreement dated
as of March 18, 1999 (the "Purchase Agreement") by and among Waste Management
Holdings, the Initial Purchasers and us. The Notes were subsequently offered by
the Initial Purchasers to qualified institutional buyers pursuant to Rule 144A
and to purchasers pursuant to Regulation S under the Securities Act.

REGISTRATION RIGHTS; LIQUIDATED DAMAGES

     The following description is a summary of the material provisions of the
Registration Rights Agreement. It does not restate that agreement in its
entirety. We urge you to read the proposed form of Registration Rights Agreement
in its entirety because it, and not this description, defines your registration
rights as holder of these Notes.

     We, the Subsidiary Guarantor and the Initial Purchasers entered into the
Registration Rights Agreement as of May 21, 1999. Pursuant to the Registration
Rights Agreement, we and the Subsidiary Guarantor agreed to file with the
Commission the Exchange Offer Registration Statement on the appropriate form
under the Securities Act with respect to the exchange of Exchange Notes for
Notes (the "Exchange Offer"). Upon the effectiveness of the Exchange Offer
Registration Statement, we agreed to offer to the holders of Transfer Restricted
Securities (as defined below) pursuant to the Exchange Offer who are able to
make certain representations the opportunity to exchange their Transfer
Restricted Securities for Exchange Notes.

     The Registration Rights Agreement provides that if:

          (1) the Exchange Offer is not permitted by applicable law or
     Commission policy; or

          (2) any holder of Transfer Restricted Securities notifies us prior to
     the 20th business day following the date by which the Exchange Offer is
     required to be consummated that:

             (a) it is prohibited by law or Commission policy from participating
        in the Exchange Offer; or

             (b) that it may not resell the Exchange Notes acquired by it in the
        Exchange Offer to the public without delivering a prospectus and the
        prospectus contained in the Exchange Offer Registration Statement is not
        appropriate or available for such resales; or

             (c) that it is a broker-dealer and owns Notes acquired directly
        from us or one of our affiliates,

then we will file with the Commission a Shelf Registration Statement to cover
resales of the Notes by the holders thereof who satisfy certain conditions
relating to the provision of information in connection with the Shelf
Registration Statement.

     "Transfer Restricted Securities" means:

          (1) Each Note, until the earliest to occur of:

             (a) the date on which such Note is exchanged in the Exchange Offer
        for an Exchange Note;

             (b) the date on which such Note has been disposed of in accordance
        with a Shelf Registration Statement (and the purchasers thereof have
        been issued Exchange Notes); and

             (c) the date on which such Note is distributed to the public
        pursuant to Rule 144 (and purchasers thereof have been issued Exchange
        Notes).

          (2) Each Exchange Note until the date on which such Exchange Note is
     disposed of by a broker-dealer pursuant to the Plan of Distribution
     contemplated by the Exchange Offer Registration Statement (including the
     delivery of the Prospectus contained therein).

                                       37
<PAGE>   43

     The Registration Rights Agreement provides that, unless the Exchange Offer
is not permitted by applicable law or Commission policy:

          (1) we will file an Exchange Offer Registration Statement with the
     Commission on or prior to 120 days after May 21, 1999;

          (2) we will use our best efforts to have the Exchange Offer
     Registration Statement declared effective by the Commission on or prior to
     210 days after May 21, 1999;

          (3) we will:

             (a) use our best efforts to cause the Exchange Offer Registration
        Statement to be continuously effective and keep the Exchange Offer open
        for not less than 20 business days or the minimum period required by
        law, if such period is no longer than 20 business days; and

             (b) use our best efforts to consummate the Exchange Offer on or
        prior to 30 business days after the date on which the Exchange Offer
        Registration Statement was declared effective by the Commission (the
        "Consummation Deadline"); and

          (4) if obligated to file the Shelf Registration Statement, we will
     file the Shelf Registration Statement with the Commission on or prior to 90
     days after such filing obligation arises and use its best efforts to cause
     the Shelf Registration to be declared effective by the Commission on or
     prior to 60 days after such Shelf Registration Statement is required to be
     filed.

     The Registration Rights Agreement provides that if:

          (1) we fail to file any of the registration statements required to be
     filed by the Registration Rights Agreement on or before the date specified
     for such filing;

          (2) any of such registration statements is not declared effective by
     the Commission on or prior to the date specified for such effectiveness;

          (3) we fail to consummate the Exchange Offer on or prior to the
     Consummation Deadline; or

          (4) the Shelf Registration Statement or the Exchange Offer
     Registration Statement is declared effective but thereafter ceases to be
     effective or usable in connection with resales of Transfer Restricted
     Securities during the periods specified in the Registration Rights
     Agreement (each such event referred to in clauses (1) through (4) above, a
     "Registration Default"),

then we will pay liquidated damages to each holder of Notes subject to such
Registration Default in an amount equal to $.05 per week per $1,000 in principal
amount of Notes held by such holder for each week or portion thereof that the
Registration Default continues for the first 90-day period immediately following
the occurrence of the first Registration Default.

     The amount of liquidated damages will increase by an additional $.05 per
week per $1,000 in principal amount of Notes with respect to each subsequent
90-day period until all Registration Defaults have been cured, up to a maximum
amount of liquidated damages of $.25 per week per $1,000 in principal amount of
Notes, provided that we will not be required to pay liquidated damages for more
than one Registration Default at any given time.

     All accrued liquidated damages will be paid directly by us on each relevant
Interest Payment Date for the Notes to the persons whose names are registered at
the close of business on the relevant Regular Record Date.

     Following the cure of all Registration Defaults, the accrual of Liquidated
Damages will cease.

     Each holder of Notes will be required to make certain representations to us
(as described in the Registration Rights Agreement) in order to participate in
the Exchange Offer and will be required to deliver certain information to be
used in connection with the Shelf Registration Statement and to provide comments
on the Shelf Registration Statement within the time periods set forth in the
Registration Rights
                                       38
<PAGE>   44

Agreement in order to have such holder's Notes included in the Shelf
Registration Statement and benefit from the provisions regarding liquidated
damages set forth above. By acquiring Notes, a holder will be deemed to have
agreed by virtue of the Registration Rights Agreement to indemnify us, against
certain losses arising out of information furnished by such holder in writing
for inclusion in any Shelf Registration Statement. Holders of Notes will also be
required to suspend their use of the prospectus included in the Shelf
Registration Statement under certain circumstances upon receipt of written
notice to that effect from us.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION

     The term "Expiration Date" shall mean                , 1999, unless we, in
our sole discretion, extend the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date to which the Exchange Offer is
extended.

     To extend the Expiration Date, we will notify the Exchange Agent of any
extension by oral or written notice and will notify the holders of the Exchange
Notes by means of a press release or other public announcement prior to 9:00
a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Such announcement may state that we are extending the
Exchange Offer for a specified period of time.

     We reserve the right (i) to delay acceptance of any Notes, to extend the
Exchange Offer or to terminate the Exchange Offer and not permit acceptance of
Notes not previously accepted if any of the conditions set forth herein under
"-- Conditions" shall have occurred and shall not have been waived by us, by
giving oral or written notice of such delay, extension or termination to the
Exchange Agent, or (ii) to amend the terms of the Exchange Offer in any manner
deemed by it to be advantageous to the holders of the Notes. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the Exchange Agent. If the
Exchange Offer is amended in a manner determined by us to constitute a material
change, we will promptly disclose such amendment in a manner reasonably
calculated to inform the holders of the Notes of such amendment.

     Without limiting the manner in which we may choose to make public
announcement of any delay, extension, amendment or termination of the Exchange
Offer, we shall have no obligations to publish, advertise, or otherwise
communicate any such public announcement, other than by making a timely release
to an appropriate news agency.

INTEREST ON THE EXCHANGE NOTES

     The Exchange Notes will accrue interest for the 2001 Exchange Notes at a
rate of 6.000% per annum, for the 2004 Exchange Notes at a rate of 6.500% per
annum, for the 2009 Exchange Notes at a rate of 6.875% per annum and for the
2029 Exchange Notes at a rate of 7.375% per annum. Interest on the Exchange
Notes will accrue from the last date on which interest was paid on the Notes,
or, if we have paid no interest on such Notes, from May 21, 1999, the date of
issuance of the Notes for which the Exchange Offer is being made. Interest on
the Exchange Notes are payable semi-annually on May 15 and November 15,
commencing on November 15, 1999.

PROCEDURES FOR TENDERING

     To tender in the Exchange Offer, you must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
medallion guaranteed if required by the Letter of Transmittal, and mail or
otherwise deliver such Letter of Transmittal or such facsimile, together with
any other required documents, to the Exchange Agent prior to 5:00 p.m., New York
City time, on the Expiration Date. In addition, either (i) a timely confirmation
of a book-entry transfer (a "Book-Entry Confirmation") of such Notes into the
Exchange Agent's account at The Depositary (the "Book-Entry Transfer Facility")
pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date or (ii) you must
comply with the guaranteed delivery procedures described below. THE METHOD OF
DELIVERY OF LETTERS OF TRANSMITTAL
                                       39
<PAGE>   45

AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND
RISK OF THE HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY TO THE
EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTERS OF TRANSMITTAL OR OTHER
REQUIRED DOCUMENTS SHOULD BE SENT TO THE COMPANY. Delivery of all documents must
be made to the Exchange Agent at its address set forth below. You may also
request your respective brokers, dealers, commercial banks, trust companies or
nominees to effect such tender.

     Your tender of Notes will constitute an agreement between you and the
Company in accordance with the terms and subject to the conditions set forth
herein and in the Letter of Transmittal. Any beneficial owner whose Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wishes to tender should contact such registered holder
promptly and instruct such registered holder to tender on his behalf.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be medallion guaranteed by any member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor" institution within
the meaning of Rule 17Ad-15 under the Exchange Act (each an "Eligible
Institution") unless the Notes tendered pursuant thereto are tendered for the
account of an Eligible Institution.

     If the Letter of Transmittal is signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations, or
others acting in a fiduciary or representative capacity, such person should so
indicate when signing, and unless waived by us, evidence satisfactory to us of
their authority to so act must be submitted with the Letter of Transmittal.

     We will determine questions as to the validity, form, eligibility
(including time of receipt) and withdrawal of the tendered Notes, in our sole
discretion, which determination will be final and binding. We reserve the
absolute right to reject any and all Notes not properly tendered or any Notes
which, if accepted, would, in the opinion of our counsel, be unlawful. We also
reserve the absolute right to waive any irregularities or conditions of tender
as to particular Notes. Our interpretation of the terms and conditions of the
Exchange Offer (including the instructions in the Letter of Transmittal) will be
final and binding on all parties. Unless waived, any defects or irregularities
in connection with tenders of Notes must be cured within such time as we shall
determine. Neither we, the Exchange Agent nor any other person shall be under
any duty to give notification of defects or irregularities with respect to
tenders of Notes, nor shall any of them incur any liability for failure to give
such notification. Tenders of Notes will not be deemed to have been made until
such irregularities have been cured or waived. The Exchange Agent will return
any Notes it receives that are not properly tendered and as to which the defects
or irregularities have not been cured or waived without cost to such holder by
the Exchange Agent, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.

     In addition, we reserve the right, in our sole discretion, subject to the
provisions of the Senior Indenture, to purchase or make offers for any Notes
that remain outstanding subsequent to the Expiration Date or, as set forth under
"-- Conditions," to terminate the Exchange Offer in accordance with the terms of
the Registration Rights Agreement, and to the extent permitted by applicable
law, purchase Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the terms
of the Exchange Offer.

ACCEPTANCE OF NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
we will accept all Notes properly tendered promptly after the Expiration Date,
and we will issue the Exchange Notes promptly after acceptance of the Notes. See
"-- Conditions." For purposes of the Exchange Offer, Notes shall be

                                       40
<PAGE>   46

deemed to have been accepted as validly tendered for exchange when, as and if we
have given oral or written notice thereof to the Exchange Agent.

     In all cases, we will issue the Exchange Notes for Notes that are accepted
for exchange pursuant to the Exchange Offer only after timely receipt by the
Exchange Agent of a Book-Entry Confirmation of such Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility, a properly completed and
duly executed Letter of Transmittal and all other required documents. If we do
not accept any tendered Notes for any reason set forth in the terms and
conditions of the Exchange Offer, we will credit such unaccepted or such
nonexchanged Notes to an account maintained with such Book-Entry Transfer
Facility as promptly as practicable after the expiration or termination of the
Exchange Offer.

BOOK-ENTRY TRANSFER

     The Exchange Agent will make a request to establish an account with respect
to the Notes at the Book-Entry Transfer Facility for purposes of the Exchange
Offer within two business days after the date of this Prospectus. Any financial
institution that is a participant in the Book-Entry Transfer Facility's systems
may make book-entry delivery of Notes by causing the Book-Entry Transfer
Facility to transfer such Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for transfer. However, the Letter of Transmittal (or
facsimile) thereof with any required signature guarantees and any other required
documents must, in any case, be transmitted to and received by the Exchange
Agent at one of the addresses set forth under "-- Exchange Agent" no later than
the Expiration Date or the guaranteed delivery procedures described below must
be complied with.

GUARANTEED DELIVERY PROCEDURES

     If the procedures for book-entry transfer cannot be completed on a timely
basis, a tender may be effected if (i) the tender is made through an Eligible
Institution, (ii) before the Expiration Date, the Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof) and Notice of Guaranteed Delivery,
substantially in the form we provided (by facsimile transmission, mail or hand
delivery), setting forth the name and address of the holder of Notes and the
amount of Notes tendered, stating that the tender is being made thereby and
guaranteeing that within three New York Stock Exchange, Inc. ("NYSE") trading
days after the date of execution of the Notice of Guaranteed Delivery, a
Book-Entry Confirmation and any other documents required by the Letter of
Transmittal will be deposited by the Eligible Institution with the Exchange
Agent, and (iii) a Book-Entry Confirmation and all other documents required by
the Letter of Transmittal are received by the Exchange Agent within three NYSE
trading days after the date of execution of the Notice of Guaranteed Delivery.

WITHDRAWAL OF TENDERS

     Tenders of Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent before 5:00 p.m., New York City time, on the
Expiration Date at one of the addresses set forth under "-- Exchange Agent." Any
such notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility from which the Notes were tendered, identify the
principal amount of the Notes to be withdrawn, and specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Notes and otherwise comply with the procedures of such Book-Entry
Transfer Facility. We will determine all questions as to the validity, form and
eligibility (including time of receipt) of such notice, and our determination
shall be final and binding on all parties. Any Notes so withdrawn will be deemed
not to have been validly tendered for exchange for purposes of the Exchange
Offer. Any Notes which have been tendered for exchange but which are not
exchanged for any reason will be credited to an account maintained with such
Book-Entry Transfer Facility for the Notes

                                       41
<PAGE>   47

as soon as practicable after withdrawal, rejection of tender or termination of
the Exchange Offer. Properly withdrawn Notes may be retendered by following one
of the procedures described under "-- Procedures for Tendering" and
"-- Book-Entry Transfer" at any time on or prior to the Expiration Date.

CONDITIONS

     Notwithstanding any other term of the Exchange Offer, Notes will not be
required to be accepted for exchange, nor will Exchange Notes be issued in
exchange for any Notes, and we may terminate or amend the Exchange Offer as
provided herein before the acceptance of such Notes, if, because of any change
in law, or applicable interpretations thereof by the Commission, we determine
that we are not permitted to effect the Exchange Offer. We have no obligation
to, and will not knowingly, permit acceptance of tenders of Notes from our
affiliates or from any other holder or holders who are not eligible to
participate in the Exchange Offer under applicable law or interpretations
thereof by the Staff of the Commission, or if the Exchange Notes to be received
by such holder or holders of Notes in the Exchange Offer, upon receipt, will not
be tradable by such holder without restriction under the Securities Act and the
Exchange Act and without material restrictions under the "blue sky" or
securities laws of substantially all of the states of the United States.

EXCHANGE AGENT

     Chase Bank of Texas, National Association has been appointed as Exchange
Agent for the Exchange Offer. You should direct your questions and requests for
assistance and requests for additional copies of this Prospectus or of the
Letter of Transmittal to the Exchange Agent addressed as follows:

     By Mail (Certified, Registered, Overnight or First Class) or Hand Delivery:

                   Chase Bank of Texas, National Association
                               600 Travis Street
                              Houston, Texas 77002
                        Telephone Number (713) 216-7000

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders pursuant to the Exchange
Offer. We are making the principal solicitation for tenders pursuant to the
Exchange Offer by mail; however we may make additional solicitations by
telegraph, telephone, telecopy or in person by our officers and regular
employees.

     We will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. We, however, will pay the Exchange
Agent reasonable and customary fees for its services and will reimburse the
Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith.

     We will bear the expenses to be incurred in connection with the Exchange
Offer, including fees and expenses of the Exchange Agent and the Trustee, and
accounting, legal, printing and related fees and expenses.

     We will pay all transfer taxes, if any, applicable to the exchange of Notes
pursuant to the Exchange Offer. If, however, Exchange Notes or Notes for
principal amounts not tendered or accepted for exchange are to be registered or
issued in the name of any person other than the registered holder of the Notes
tendered, or if tendered Notes are registered in the name of any person other
than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.

                                       42

RESALE OF EXCHANGE NOTES

     Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, we believe that Exchange Notes issued
pursuant to the Exchange Offer in exchange for Notes may be offered for resale,
resold and otherwise transferred by any owner of such Exchange Notes (other than
any such owner which is our "affiliate" within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus delivery
provisions of the Securities Act, if such Exchange Notes are acquired in the
ordinary course of such owner's business and such owner does not intend to
participate, and has no arrangement or understanding with any person to
participate, in the distribution of such Exchange Notes. Any owner of Notes who
tenders in the Exchange Offer with the intention to participate, or for the
purpose of participating, in a distribution of the Exchange Notes may not rely
on the position of the staff of the Commission enunciated in the "Exxon Capital
Holdings Corporation" or similar no-action letters but rather must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. In addition, any such resale transaction
should be covered by an effective registration statement containing the selling
security holders information required by Item 507 of Regulation S-K of the
Securities Act. Each broker-dealer that receives Exchange Notes for its own
account in exchange for Notes, where such Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, may be a statutory underwriter and must acknowledge that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such Exchange Notes.

     By tendering in the Exchange Offer, each Holder (or DTC participant, in the
case of tenders of interests in the Global Notes held by DTC) will represent to
us (which representation may be contained the Letter of Transmittal) to the
effect that (A) it is not our affiliate, (B) it is not engaged in, and does not
intend to engage in, and has no arrangement or understanding with any person to
participate in, a distribution of the Exchange Notes to be issued in the
Exchange Offer and (C) it is acquiring the Exchange Notes in its ordinary course
of business. Each Holder will acknowledge and agree that any broker-dealer and
any such Holder using the Exchange Offer to participate in a distribution of the
Exchange Notes acquired in the Exchange Offer (1) could not under Commission
policy as in effect on the date of the Registration Rights Agreement rely on the
position of the Commission enunciated in the No-Action Letters, and (2) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction and that such a
secondary resale transaction must be covered by an effective registration
statement containing the selling security holder information required by Item
507 or 508, as applicable, of Regulation S-K if the resales are of Exchange
Notes obtained by such Holder in exchange for Notes acquired by such Holder
directly from us or our affiliate.

     To comply with the securities laws of certain jurisdictions, it may be
necessary to qualify for sale or to register the Exchange Notes before offering
or selling such Exchange Notes. We have agreed, pursuant to the Registration
Rights Agreement and subject to certain specified limitations therein, to
cooperate with selling Holders or underwriters in connection with the
registration and qualification of the Exchange Notes for offer or sale under the
securities or "blue sky" laws of such jurisdictions as may be necessary to
permit the holders of Exchange Notes to trade the Exchange Notes without any
restrictions or limitations under the securities laws of the several states of
the United States.

CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders of Notes who do not exchange their Notes for Exchange Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Notes as set forth in the legend thereon as a consequence of
the issuance of the Notes pursuant to exemptions from, or in transactions not
subject to, the registration requirements of the Securities Act and applicable
state securities laws. We do not currently anticipate that we will register the
Notes under the Securities Act. To the extent that Notes are tendered and
accepted in the Exchange Offer, the trading market for untendered and tendered
but unaccepted Notes could be adversely affected.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the principal United States federal income
tax consequences from the Exchange Offer and from the ownership of the Notes or
Exchange Notes. It deals only with Notes or Exchange Notes held as capital
assets and not with special classes of Holders, such as dealers in securities or
currencies, life insurance companies, tax exempt entities, and persons that hold
a Note or an Exchange Note in connection with an arrangement that completely or
partially hedges the Note or Exchange Note. Further, the discussion does not
address all aspects of taxation that might be relevant to particular Holders in
light of their individual circumstances. The discussion is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), and regulations, rulings
and judicial decisions thereunder as of the date hereof. Such authorities may be
repealed, revoked or modified so as to result in federal income tax consequences
different from those discussed below.

     For purposes of the following discussion, a "U.S. Holder" means a
beneficial owner of a Note or an Exchange Note that is, for United States
federal income tax purposes: (1) a citizen or resident of the United States; (2)
a partnership, corporation or other entity created or organized in or under the
law of the United States or of any State of the United States; (3) an estate,
the income of which is subject to United States federal income tax regardless of
its source; (4) a trust classified as a United States person for United States
federal income tax purposes. A "Non-U.S. Holder" is a beneficial owner of a Note
or an Exchange Note that, for United States federal income tax purposes, is not
a U.S. Holder.

     HOLDERS TENDERING THEIR NOTES OR PROSPECTIVE PURCHASERS OF EXCHANGE NOTES
SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED STATES FEDERAL
INCOME TAX AND ANY STATE OR LOCAL TAX CONSEQUENCES OF THE EXCHANGE OF THE NOTES
FOR EXCHANGE NOTES, AND OF THE OWNERSHIP AND DISPOSITION OF THE NOTES OR
EXCHANGE NOTES IN LIGHT OF THEIR PARTICULAR SITUATIONS, AND ANY CONSEQUENCES
UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION.

EXCHANGE OF NOTES FOR EXCHANGE NOTES

     The exchange of Notes for Exchange Notes pursuant to the Exchange Offer
will not be treated as an "exchange" for United States federal income tax
purposes because the Notes will not be considered to differ materially in kind
or extent from the Exchange Notes. Rather, the Exchange Notes received by a
Holder will be treated as a continuation of the Notes in the hands of such
Holder. The adjusted basis and holding period of the Exchange Notes for any
Holder will be the same as the adjusted basis and holding period of the Notes.
Similarly, there will be no United States federal income tax consequences to a
Holder of Notes that does not participate in the exchange offer.

TAX CONSEQUENCES TO U.S. HOLDERS

     Payments of Interest. Payments of stated interest on a Note or an Exchange
Note generally will be taxable to a U.S. Holder as ordinary interest income at
the time it is received or accrued, depending on the U.S. Holder's method of
accounting for tax purposes.

     Sale, Exchange, Redemption or Retirement. Upon the sale, exchange,
redemption or retirement of a Note or an Exchange Note, a U.S. Holder will
recognize taxable gain or loss equal to the difference between the amount
realized on such sale, exchange, redemption or retirement (not including any
amount attributable to accrued but unpaid interest not previously included in
gross income) and such Holder's adjusted tax basis in the Note or Exchange Note.
To the extent attributable to accrued but unpaid interest not previously
included in gross income, the amount recognized by the U.S. Holder will be
treated as a payment of interest. See "-- Payments of Interest." Gain or loss
recognized on the sale, exchange, redemption or retirement generally will be
capital gain or loss. The deductibility of capital losses is subject to
limitations.

                                       44
<PAGE>   50

     Market Discount and Premium. U.S. Holders that did not acquire their
interest in the Exchange Notes pursuant to an acquisition of Notes on their
original issue at their original offering price or pursuant to an exchange of
such Notes for Exchange Notes pursuant to the exchange offer may be considered
to have acquired their Exchange Notes with market discount or amortizable bond
premium as such terms are defined for United States federal income tax purposes.
Such Holders should consult their tax advisors as to the federal income tax
consequences of the market discount and premium rules of the Code.

     Backup Withholding. Payments made on, and proceeds from the sale of, Notes
or Exchange Notes may be subject to a "backup" withholding tax of 31% unless the
Holder complies with certain identification requirements. Any withheld amounts
will generally be allowed as a credit against the Holder's federal income tax
provided the required information is timely filed with the IRS.

TAX CONSEQUENCES TO NON-U.S. HOLDERS

     Interest. The so-called "portfolio interest" exception provides that
interest on the Notes or Exchange Notes will not be subject to U.S. federal
income tax and withholding of U.S. federal income tax will not be required with
respect to the payment by us or our paying agent of principal or interest on the
Notes or Exchange Notes owned by a Non-U.S. Holder, provided that (1) the
beneficial owner of the Notes or Exchange Notes does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of the Company entitled to vote within the meaning of Section 871(h)(3)
of the Tax Code and the Treasury Regulations issued thereunder, (2) the
beneficial owner is not (i) a foreign tax exempt organization or a foreign
private foundation for U.S. federal income tax purposes, (ii) a bank whose
receipt of interest on the Notes or Exchange Notes is described in Section
881(c)(3)(A) of the Tax Code or (iii) a "controlled foreign corporation" (as
defined Section 957 of the Tax Code) that is related directly, indirectly or
constructively to us through stock ownership, (3) such interest is not
considered contingent interest under Section 871(h)(4) of the Tax Code and the
Treasury Regulations thereunder, and (4) the beneficial owner satisfies the
requirements (described generally below) set forth in Section 871(h) and Section
881(c) of the Tax Code and the Treasury Regulations thereunder relating to
registered securities.

     To satisfy the requirements referred to in (4) above, the beneficial owner
of such Notes or Exchange Notes, or a financial institution holding the Notes or
Exchange Notes on behalf of such owner, must provide, in accordance with
specified procedures, our paying agent with a statement to the effect that the
beneficial owner is not a U.S. person. Currently, these requirements will be met
if either (i) the beneficial owner of the Notes or Exchange Notes certifies to
us or our paying agent, under penalties of perjury, that it is not a U.S. person
(which certification may be made on an IRS Form W-8 or successor form) and
provides its name and address or (ii) a securities clearing organization, bank
or other financial institution that holds customers' securities in the ordinary
course of its trade or business (a "financial institution") and that holds the
Notes or Exchange Notes on behalf of a beneficial owner, certifies to us or our
paying agent, under penalties of perjury, that such statement has been received
by it from the beneficial owner (directly or through another intermediary
financial institution), and furnishes us or our paying agent with a copy
thereof. A certificate described in this paragraph is effective only with
respect to payments of interest made to the certifying Non-U.S. Holder after the
issuance of the certificate, in the calendar year of its issuance and two
immediately succeeding calendar years.

     Treasury Regulations (the "Final Regulations") finalized in 1997,
applicable to interest paid after December 31, 1999, provide alternative
documentation procedures for satisfying the certification requirement described
above. However, the Department of the Treasury and the IRS have announced their
intention to extend the dates of applicability of the Final Regulations to
payments made after December 31, 2000. Such regulations add intermediary
certification options for certain qualifying agents. Under one such option, a
withholding agent would be allowed to rely on IRS Form W-8 furnished by a
financial institution or other intermediary on behalf of one or more beneficial
owners (or other intermediaries) without having to obtain the beneficial owner
certificate described in the preceding paragraph, provided that the financial
institution or intermediary has entered into a withholding agreement with the
IRS and thus is a "qualified intermediary." Under another option, an authorized
foreign agent of
                                       45
<PAGE>   51

a U.S. withholding agent would be permitted to act on behalf of the U.S.
withholding agent, provided certain conditions are met. With respect to the
certification requirement for Notes or Exchange Notes that are held by a foreign
partnership, the Final Regulations provide that unless the foreign partnership
has entered into a withholding agreement with the IRS, the foreign partnership
will be required, in addition to providing an intermediary Form W-8, to attach
an appropriate certification by each partner. Prospective investors, including
foreign partnerships and their partners, should consult their tax advisors
regarding possible additional reporting requirements.

     If a Non-U.S. Holder cannot satisfy the requirements of the "portfolio
interest" exception described above, payments of interest made to such Non-U.S.
Holder will generally be subject to withholding tax of 30% unless the beneficial
owner of the Notes or Exchange Notes provides us or our paying agent, as the
case may be, with a properly executed (i) IRS Form 1001 (or successor form)
claiming an exemption from or reduced rate of withholding under the benefit of a
tax treaty or (ii) IRS Form 4224 (or successor form) stating that interest paid
on the Notes or Exchange Notes is not subject to withholding tax because it is
effectively connected with the beneficial owner's conduct of a trade or business
in the United States. Under the Final Regulations, Non-U.S. Holders will
generally be required to provide IRS Form W-8BEN, W-8IMY, W-8EXP, or W-8ECI in
lieu of Form 1001 and Form 4224, although alternative documentation may be
applicable in certain situations. Additionally, the Non-U.S. Holders will be
required to obtain U.S. taxpayer identification numbers. In each such case, the
relevant IRS form must be delivered pursuant to applicable procedures and must
be properly transmitted to the person otherwise required to withhold U.S.
federal income tax, and none of the persons receiving the relevant form may have
actual knowledge that any statement on the form is false.

     Gain on Disposition of Notes or Exchange Notes. A Non-U.S. Holder will not
be subject to withholding of U.S. federal income tax on any gain realized on the
sale, exchange, retirement, or other disposition of the Notes or Exchange Notes,
unless (i) such Holder is an individual who is present in the United States for
183 days or more during the taxable year and certain other requirements are met,
or (ii) the gain is effectively connected with the conduct of a United States
trade or business of the Holder.

     Federal Estate Taxes. Under Section 2105(b) of the Tax Code, if interest on
the Notes or Exchange Notes would be exempt from withholding of U.S. federal
income tax under the rules described under "-- Interest" (without regard to the
statement requirement), the Notes or Exchange Notes will not be included in the
estate of a Non-U.S. Holder for U.S. federal estate tax purposes.

     Effectively Connected Income. If a Non-U.S. Holder is engaged in a trade or
business in the United States and interest on the Notes or Exchange Notes (or
gain realized on the sale, exchange or other disposition of the Notes or
Exchange Notes) is effectively connected with the conduct of such trade or
business, the Non-U.S. Holder, although exempt from the withholding tax
discussed above, will generally be subject to U.S. federal income tax on such
effectively connected income in the same manner as if it were a U.S. person.
Under the Final Regulations, such Non-U.S. Holder may also need to provide a
United States taxpayer identification number (social security number or employer
identification number) on forms referred to under "-- Interest" in order to meet
the requirements set forth above. In addition, if such Non-U.S. Holder is a
foreign corporation, it may be subject to a branch profits tax equal to 30% of
its effectively connected earnings and profits for the taxable year, subject to
adjustments. For this purpose, interest on, and any gain recognized on the sale,
exchange or other disposition of, the Notes or Exchange Notes will be included
in such foreign corporation's effectively connected earnings and profits if such
interest or gain, as the case may be, is effectively connected with the conduct
by such foreign corporation of a trade or business in the United States.

     Backup Withholding and Information Reporting. Certain "backup" withholding
and information reporting requirements may apply to payments on, and to proceeds
of sale before maturity of, the Notes or Exchange Notes. Interest paid to a
Non-U.S. Holder on a registered security will be required to be reported
annually on IRS Form 1042-S. We are not obligated to reimburse or indemnify
Holders of the Notes or Exchange Notes, including Non-U.S. Holders, for any tax
imposed on, or withheld from payments with respect to the Notes or Exchange
Notes.

                                       46
<PAGE>   52

     No information reporting on IRS Form 1099 or backup withholding will be
required with respect to payments made by us or any paying agent to Non-U.S.
Holders on registered securities with respect to which a statement described
under "-- Interest" has been received; provided that we or our paying agent, as
the case may be, does not have actual knowledge that the beneficial owner is a
U.S. person.

     In addition, backup withholding and information reporting will not apply if
payments of principal or interest on the Notes or Exchange Notes are paid to or
collected by a foreign office of a custodian, nominee or other foreign agent on
behalf of the beneficial owner of such Notes or Exchange Notes, or if the
foreign office of a broker (as defined in applicable Treasury Regulations) pays
the proceeds of the sale of the Notes or Exchange Notes to the owner thereof.
If, however, such nominee, custodian, agent or broker is, for U.S. federal
income tax purposes, a U.S. person, a controlled foreign corporation or a
foreign person 50% or more of whose gross income is effectively connected with
the conduct of a United States trade or business for a specified three-year
period, or another United States related person described in Section
1.6049-5(c)(5) of the Treasury Regulations, then information reporting will be
required unless (i) such custodian, nominee, agent or broker has in its records
documentary evidence that the beneficial owner is not a U.S. person and certain
other conditions are met or (ii) the beneficial owner otherwise establishes an
exemption.

     Payments of principal and interest on the Notes or Exchange Notes to the
beneficial owner of such Notes or Exchange Notes by a United States office of a
custodian, nominee or agent, or payment by the United States office of a broker
of the proceeds of the sale of the Notes or Exchange Notes, will be subject to
information reporting and backup withholding unless the Holder or beneficial
owner provides the statement described under "-- Interest" or otherwise
establishes an exemption from information reporting and backup withholding, and
the payor does not have actual knowledge that the beneficial owner is a U.S.
person.

     Applicable Tax Treaties. Non-U.S. Holders should also consult any
applicable income tax treaties, which may provide for a lower rate of
withholding tax, exemption from or reduction of branch profits tax, or other
rules different from those under United States federal tax laws.

                                       47

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of the Exchange Notes received in
exchange for the Notes where such Notes were acquired as a result of
market-making activities or other trading activities. The Company has agreed
that, starting on the Expiration Date and ending on the close of business on the
first anniversary of the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale.

     The Company will not receive any proceeds from any sale of the Exchange
Notes by broker-dealers. The Exchange Notes received by broker-dealers for their
own account pursuant to the Exchange Offer may be sold from time to time in one
or more transactions in the over-the counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices or negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"Underwriter" within the meaning of the Securities Act and any profit of any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "Underwriter" within the meaning of the Securities Act.

     For a period of one year after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer and will indemnify the holders of the Exchange
Notes against certain liabilities, including liabilities under the Securities
Act.

                                 LEGAL MATTERS

     Locke Liddell & Sapp LLP will opine on the validity of the Exchange Notes
for us.

                                    EXPERTS


     The audited consolidated financial statements for the year ended December
31, 1998 appearing in Waste Management's Current Report on Form 8-K dated
September 16, 1999 incorporated by reference in this prospectus have been
audited by Arthur Andersen LLP, independent public accountants, as set forth in
their report. In their report, that firm states that, with respect to USA Waste
Services, Inc. and its Subsidiaries as of December 31, 1997 and for each of the
years in the two-year period then ended, its opinion is based on reports of
other auditors, namely PricewaterhouseCoopers LLP. The financial statements of
Waste Management referred to above have been included herein in reliance upon
the authority of those firms as experts in giving said reports.



     During the quarter ended September 30, 1999, the Company conducted a review
of its accounting records, systems, processes and controls. Based on that
review, the Company has concluded that its internal controls for the preparation
of interim financial information did not provide its independent public
accountants an adequate basis to complete reviews of the quarterly data for the
quarters in the nine-month period ended September 30, 1999. Our independent
public accountants have advised the Company that their report on the December
31, 1999 financial statements will include the following paragraph:



        "The selected quarterly financial data included in the Company's
        financial statements contain information that we did not audit, and
        accordingly, we do not express an opinion on that data. We attempted,
        but were unable to, review that quarterly data in accordance with
        standards established by the American Institute of Certified Public
        Accountants because we believe that the Company's internal controls for
        the preparation of interim financial information do not provide an
        adequate basis to enable us to complete such a review."


     The audited consolidated financial statements of USA Waste Services, Inc.
as of December 31, 1997 and for the years ended December 31, 1997 and 1996, not
separately incorporated by reference in this prospectus, have been audited by
PricewaterhouseCoopers LLP, independent accountants, whose report thereon is
incorporated by reference herein. Such financial statements, to the extent they
have been included in the financial statements of Waste Management, Inc., have

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102 of the Delaware General Corporation Law ("DGCL") allows a
corporation to eliminate the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except in cases where the director breached his or her duty of loyalty
to the corporation or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of the law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
unlawful stock redemption or repurchase or obtained an improper personal
benefit. The Registrant's Restated Certificate of Incorporation (the "Waste
Management Charter") contains a provision which eliminates directors' personal
liability as set forth above.

     The Waste Management Charter and the Bylaws of Waste Management provide in
effect that the Registrant shall indemnify its directors and officers, and may
indemnify its employees and agents, to the extent permitted by the DGCL. Section
145 of the DGCL provides that a Delaware corporation has the power to indemnify
its directors, officers, employees and agents in certain circumstances.

     Subsection (a) of Section 145 of the DGCL empowers a corporation to
indemnify any director, officer, employee or agent, or former director, officer,
employee or agent 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), against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with such action, suit or proceeding provided that such director,
officer, employee or agent acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, provided
that such director, officer, employee or agent had no reasonable cause to
believe that his or her conduct was unlawful.

     Subsection (b) of Section 145 of the DGCL empowers a corporation to
indemnify any director, officer, employee or agent, or former director, officer,
employee or agent, who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred in connection with
the defense or settlement of such action or suit provided that such person acted
in good faith and in a manner he or she reasonably believed to be in or not
opposed to the best interests of the corporation, except that no indemnification
may 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 shall determine that, despite the adjudication
of liability, such person is fairly and reasonably entitled to indemnity for
such expenses which the court shall deem proper.

     Section 145 of the DGCL further provides that, to the extent that a
director or officer of a corporation has been successful in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
of the DGCL or in the defense of any claim, issue or matter therein, he or she
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection therewith; that indemnification
provided by Section 145 of the DGCL shall not be deemed exclusive of any other
rights to which the party seeking indemnification may be entitled; and the
corporation is empowered to purchase and maintain insurance on behalf of a
director, officer, employee or agent of the corporation against any liability
asserted against him or her or incurred by him or her in any such capacity or
arising out of his or her status as such whether or not the corporation would
have the power to indemnify him or her against such liabilities under Section
145 of the DGCL; and that, unless indemnification is ordered by a court, the
determination that indemnification under subsections (a) and (b) of Section 145
of the DGCL is proper because the director, officer, employee or

                                      II-1
<PAGE>   57

agent has met the applicable standard of conduct under such subsections shall be
made with respect to a person who is a director or officer at the time of such
determination (1) by a majority vote of the directors who are not parties to
such action, suit or proceeding, even though less than a quorum, or (2) by a
committee of such directors designated by majority vote of such directors, even
though less than a quorum, or (3) if there are no such directors, or if such
directors so direct, by independent legal counsel in a written opinion, or (4)
by the stockholders.

     The Registrant has purchased certain liability insurance for its officers
and directors as permitted by Section 145(g) of the DGCL.

     The Registrant has entered into Indemnification Agreements with certain of
its directors and executive officers. Such Indemnification Agreements provide
that such persons (the "Indemnitees") will be indemnified and held harmless from
all expenses, including (without limitation) reasonable fees and expenses of
counsel, and all liabilities, including (without limitation) the amount of any
judgments, fines, penalties, excise taxes and amounts paid in settlement,
actually incurred by an Indemnitee with respect to any threatened, pending or
completed claim, action (including any action by or in the right of the
Registrant), suit or proceeding (whether formal or informal, or civil, criminal,
administrative, legislative, arbitrative or investigative) in respect of which
such Indemnitee is, was or at any time becomes, or is threatened to be made, a
party, witness, subject or target, by reason of the fact that such Indemnitee is
or was a director, officer, agent or fiduciary of the Registrant or serving at
the request of the Registrant as a director, officer, employee, fiduciary or
representative of another enterprise. Such Indemnification Agreements also
provide that the Registrant, if requested to do so by an Indemnitee, will
advance to such Indemnitee, prior to final disposition of any proceeding, the
expenses actually incurred by the Indemnitee subject to the obligation of the
Indemnitee to refund if it is ultimately determined that such Indemnitee was not
entitled to Indemnification.

ITEM 22. UNDERTAKINGS

     The undersigned registrants hereby undertake:

          (1) That, for purposes of determining any liability under the
     Securities Act, each filing of the registrant's annual report pursuant to
     section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that
     is incorporated by reference in this registration statement shall be deemed
     to be a new registration statement relating to the securities offered
     herein, and the offering of such securities at that time shall be deemed to
     be the initial bona fide offering thereof.

          (2) 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 provisions described under Item
     20 above, 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 as
     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 be governed by the final
     adjudication of such issue.

          (3) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this
     Form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

          (4) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.

                                       17



         SECTION 2.2. FACILITY FEE. The Borrower agrees to pay to the
Administrative Agent for the account of the Banks a fee (the "Facility Fee") on
the Total Commitment equal to the Applicable Facility Rate multiplied by the
Total Commitment. The Facility Fee shall be payable for the period from and
after the Effective Date quarterly in arrears on the first day of each calendar
quarter for the immediately preceding calendar quarter with the first such
payment commencing on January 1, 2000 and with a final payment on the Maturity
Date (or on the date of termination in full of the Total Commitment, if
earlier). The Facility Fee shall be distributed pro rata among the Banks in
accordance with each Bank's Commitment Percentage.

         SECTION 2.3. REDUCTION OF TOTAL COMMITMENT.

                  (a) The Borrower shall have the right at any time and from
         time to time upon three (3) Business Days' prior written notice to the
         Administrative Agent to reduce by $25,000,000 or a greater amount or
         terminate entirely, the Total Commitment, whereupon each Bank's
         Commitment shall be reduced pro rata in accordance with such Bank's
         Commitment Percentage of the amount specified in such notice or, as the
         case may be, terminated provided that at no time may (i) the Total
         Commitment be reduced to an amount less than the sum of (A) the Maximum
         Drawing Amount of all Letters of Credit, and (B) all Loans then
         outstanding.

                  (b) The Total Commitment shall be automatically reduced as
         required pursuant to Section Section 8.4(c) and (d), whereupon each
         Bank's Commitment shall be reduced pro rata in accordance with such
         Bank's Commitment Percentage of the amount terminated.

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

                  (d) The Administrative Agent will notify the Banks promptly
         after receiving any notice delivered by the Borrower pursuant to this
         Section 2.3 and will distribute to each Bank a revised Schedule 1 to
         this Agreement.

         SECTION 2.4.  THE SYNDICATED NOTES.

                  (a) The Syndicated Loans shall be evidenced by separate
         promissory notes of the Borrower in substantially the form of Exhibit A
         hereto (each, a "Syndicated Note"), dated as of the Effective Date (or
         such later date at which a Bank becomes a party hereto pursuant to
         Section 20) and completed with appropriate insertions. One Syndicated
         Note shall be payable to the order of each Bank in an amount equal to
         its maximum Commitment, and shall represent the obligation of the
         Borrower to pay such Bank such principal amount or, if less, the
         outstanding principal amount of all Syndicated Loans made by such Bank,
         plus interest accrued thereon, as set forth herein.

                  (b) The Borrower irrevocably authorizes each Bank to make, or
         cause to be made, in connection with a Drawdown Date of any Syndicated
         Loan and at the time of receipt of any payment of principal on its
         Syndicated Note, an appropriate notation on



<PAGE>   24
                                       18


         such Bank's records or on the schedule attached to such Bank's
         Syndicated Note or a continuation of such schedule attached thereto
         reflecting the making of such Loan, or the receipt of such payment (as
         the case may be) and each Bank may, prior to any transfer of its
         Syndicated Note endorse on the reverse side thereof the outstanding
         principal amount of such Loans evidenced thereby. The outstanding
         amount of the Loans set forth on such Bank's records 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 obligations of the
         Borrower hereunder or under such Notes to make payments of principal of
         or interest on any such Notes when due.

         SECTION 2.5.  INTEREST ON LOANS.

                  (a) The outstanding principal amount of the Syndicated Loans
         shall bear interest at the rate per annum equal to (i) the Base Rate on
         Base Rate Loans, (ii) the Applicable Eurodollar Rate on Eurodollar
         Loans and (iii) the Applicable Swing Line Rate on Swing Line Loans.

                  (b) Interest shall be payable (i) monthly in arrears on the
         first Business Day of each month, with the first such payment
         commencing January 1, 2000, on Base Rate Loans, (ii) on the last day of
         the applicable Interest Period, and if such Interest Period is longer
         than three months, also on the last day of each three month period
         following the commencement of such Interest Period, on Eurodollar
         Loans, and (iii) on the Maturity Date for all Loans.

         SECTION 2.6.  REQUESTS FOR SYNDICATED LOANS.

                  (a) The Borrower shall give to the Administrative Agent
written notice in the form of Exhibit D hereto (or telephonic notice confirmed
in writing or a facsimile in the form of Exhibit D hereto) of each Syndicated
Loan requested hereunder (a "Syndicated Loan Request") not later than (a) 11:00
a.m. (New York time) on the proposed Drawdown Date of any Base Rate Loan, or (b)
11:00 a.m. (New York time) three (3) Eurodollar Business Days prior to the
proposed Drawdown Date of any Eurodollar Loan. Each such Syndicated Loan Request
shall specify (A) the principal amount of the Syndicated Loan requested, (B) the
proposed Drawdown Date of such Syndicated Loan, (C) whether such Syndicated Loan
requested is to be a Base Rate Loan or a Eurodollar Loan, and (D) the Interest
Period for such Syndicated Loan, if a Eurodollar Loan. Each Syndicated Loan
requested shall be in a minimum amount of $10,000,000. Each such Syndicated Loan
Request shall reflect the Maximum Drawing Amount of all Letters of Credit
outstanding and the amount of all Loans outstanding (including Competitive Bid
Loans and Swing Line Loans). Syndicated Loan Requests made hereunder shall be
irrevocable and binding on the Borrower, and shall obligate the Borrower to
accept the Syndicated Loan requested from the Banks on the proposed Drawdown
Date.

         (b) Each of the representations and warranties made by the Borrower to
the Banks or the Administrative Agent in this Agreement or any other Loan
Document shall be true and correct in all material respects when made and shall,
for all purposes of this Agreement, be deemed to be repeated by the Borrower on
and as of the date of the submission of a Syndicated



<PAGE>   25

                                       19



Loan Request, Competitive Bid Quote Request, or Letter of Credit Application and
on and as of the Drawdown Date of any Loan or the date of issuance of any Letter
of Credit (except to the extent (i) of changes resulting from transactions
contemplated or permitted by this Agreement and the other Loan Documents, (ii)
of changes occurring in the ordinary course of business that singly or in the
aggregate are not materially adverse to the business, assets or financial
condition of the Borrower and its Subsidiaries as a whole, or (iii) that such
representations and warranties expressly relate only to an earlier date).

         (c) The Administrative Agent shall promptly notify each Bank of each
Syndicated Loan Request received by the Administrative Agent (i) on the proposed
Drawdown Date of any Base Rate Loan, or (ii) three (3) Eurodollar Business Days
prior to the proposed Drawdown Date of any Eurodollar Loan.

         SECTION 2.7. ELECTION OF EURODOLLAR RATE; NOTICE OF ELECTION; INTEREST
PERIODS; MINIMUM AMOUNTS.

                  (a) At the Borrower's option, so long as no Default or Event
         of Default has occurred and is then continuing, the Borrower may (i)
         elect to convert any Base Rate Loan or a portion thereof to a
         Eurodollar Loan, (ii) at the time of any Syndicated Loan Request,
         specify that such requested 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 Borrower give
         notice to the Administrative Agent pursuant to Section 2.7(b) hereof.
         Upon determining any Eurodollar Rate, the Administrative Agent shall
         forthwith provide notice thereof to the Borrower and the Banks, and
         each such notice to the Borrower 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 Borrower shall
         give written, telex or facsimile notice (or telephonic notice promptly
         confirmed in a writing or a facsimile) received by the Administrative
         Agent not later than 11:00 a.m. (New York time) of its election
         pursuant to Section 2.7(a). Each such notice delivered to the
         Administrative Agent shall specify the aggregate principal amount of
         the Syndicated 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 Borrower. If the Borrower shall fail to give the
         Administrative Agent notice of its election hereunder together with all
         of the other information required by this Section 2.7(b) with respect
         to any Syndicated Loan, whether at the end of an Interest Period or
         otherwise, such Syndicated Loan shall be deemed a Base Rate Loan. The
         Administrative Agent shall promptly notify the Banks in writing (or by
         telephone confirmed in writing or by facsimile) of such election.

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


<PAGE>   26


                                       20


                  (d) No conversion of Loans pursuant to this Section 2.7 may
         result in Eurodollar Loans that are less than $5,000,000. In no event
         shall the Borrower have more than eight (8) different Interest Periods
         for borrowings of Eurodollar Loans outstanding at any time.

                  (e) Subject to the terms and conditions of Section 5.8 hereof,
         if any Affected Bank demands compensation under Section 5.5(c) or (d)
         with respect to any Eurodollar Loan, the Borrower may at any time, upon
         at least three (3) Business Days' prior written notice to the
         applicable Administrative Agent, elect to convert such Eurodollar Loan
         into a Base Rate Loan (on which interest and principal shall be payable
         contemporaneously with the related Eurodollar Loans of the other
         Banks). Thereafter, and until such time as the Affected Bank notifies
         the Administrative Agent that the circumstances giving rise to the
         demand for compensation under Section 5.5(c) or (d) no longer exist,
         all requests for Eurodollar Loans from such Affected Bank shall be
         deemed to be requests for Base Rate Loans. Once the Affected Bank
         notifies the Administrative Agent that such circumstances no longer
         exist, the Borrower may elect that the principal amount of each such
         Loan converted hereunder shall again bear interest as Eurodollar Loans
         beginning on the first day of the next succeeding Interest Period
         applicable to the related Eurodollar Loans of the other Banks.

         SECTION 2.8. FUNDS FOR SYNDICATED LOANS. Not later than 1:00 p.m. (New
York time) on the proposed Drawdown Date of Syndicated Loans, each of the Banks
will make available to the Administrative Agent at its Head Office, in
immediately available funds, the amount of its Commitment Percentage of the
amount of the requested Loan. Upon receipt from each Bank of such amount, and
upon receipt of the documents required by Section 10 and Section 11 and the
satisfaction of the other conditions set forth therein, the Administrative Agent
will make available to the Borrower the aggregate amount of such Syndicated
Loans made available by the Banks. The failure or refusal of any Bank to make
available to the Administrative Agent at the aforesaid time and place on any
Drawdown Date the amount of its Commitment Percentage of the requested
Syndicated Loan shall not relieve any other Bank from its several obligations
hereunder to make available to the Administrative Agent the amount of such
Bank's Commitment Percentage of the requested Loan.

         SECTION 2.9. MATURITY OF THE LOANS AND REIMBURSEMENT OBLIGATIONS. The
Borrower promises to pay on the Maturity Date, and there shall become absolutely
due and payable on the Maturity Date, all of the Loans and unpaid Reimbursement
Obligations outstanding on such date, together with any and all accrued and
unpaid interest thereon and any fees and other amounts owing hereunder.

         SECTION 2.10. OPTIONAL PREPAYMENTS OR REPAYMENTS OF LOANS. Subject to
the terms and conditions of Section 5.8, the Borrower shall have the right, at
its election, to repay or prepay the outstanding amount of the Loans, as a whole
or in part, at any time without penalty or premium. The Borrower shall give the
Administrative Agent no later than 11:00 a.m. (New York time) (a) on the
proposed date of prepayment or repayment of Base Rate Loans and (b) three (3)
Business Day prior to the proposed date of prepayment or repayment of all other
Loans, written notice (or telephonic notice confirmed in writing or by
facsimile) of any proposed prepayment or repayment pursuant to this Section
2.10, specifying the proposed date of prepayment or repayment of




<PAGE>   27
                                       21


Loans and the principal amount to be paid. Notwithstanding the foregoing, the
Borrower may not prepay any Competitive Bid Loans. The Administrative Agent
shall promptly notify each Bank by written notice (or telephonic notice
confirmed in writing or by facsimile) of such notice of payment.

         SECTION 2.11.  SWING LINE LOANS; SETTLEMENTS.

                  (a) Solely for ease of administration of the Syndicated Loans,
         MGT may, but shall not be required to, fund Base Rate Loans made in
         accordance with the provisions of this Agreement ("Swing Line Loans").
         The Swing Line Loans shall be evidenced by a promissory note of the
         Borrower in substantially the form of Exhibit B hereto (the "Swing Line
         Note") and, at the discretion of MGT may be in amounts less than
         $10,000,000 provided that the outstanding amount of Swing Line Loans
         advanced by MGT hereunder shall not exceed $10,000,000 at any time.
         Each Bank shall remain severally and unconditionally liable to fund its
         pro rata share (based upon each Bank's Commitment Percentage) of such
         Swing Line Loans on each Swing Line Settlement Date and, in the event
         MGT chooses not to fund all Base Rate Loans requested on any date, to
         fund its Commitment Percentage of the Base Rate Loans requested,
         subject to satisfaction of the provisions hereof relating to the making
         of Base Rate Loans. Prior to each Swing Line Settlement, all payments
         or repayments of the principal of, and interest on, Swing Line Loans
         shall be credited to the account of MGT.

                  (b) The Banks shall effect Swing Line Settlements on (i) the
         Business Day immediately following any day which MGT gives written
         notice to the Administrative Agent to effect a Swing Line Settlement,
         (ii) the Business Day immediately following the Administrative Agent's
         becoming aware of the existence of any Default or Event of Default and
         (iii) the Maturity Date (each such date, a "Swing Line Settlement
         Date"). One (1) Business Day prior to each such Swing Line Settlement
         Date, the Administrative Agent shall give telephonic notice to the
         Banks of (A) the respective outstanding amount of Syndicated Loans made
         by each Bank as at the close of business on the prior day, (B) the
         amount that any Bank, as applicable (a "Swing Line Settling Bank"),
         shall pay to effect a Swing Line Settlement (a "Swing Line Settlement
         Amount") and (C) the portion (if any) of the aggregate Swing Line
         Settlement Amount to be paid to each Bank. A statement of the
         Administrative Agent submitted to the Banks with respect to any amounts
         owing hereunder shall be prima facie evidence of the amount due and
         owing. Each Swing Line Settling Bank shall, not later than 1:00 p.m.
         (New York time) on each Swing Line Settlement Date, effect a wire
         transfer of immediately available funds to the Administrative Agent at
         its Head Office in the amount of such Bank's Swing Line Settlement
         Amount. The Administrative Agent shall, as promptly as practicable
         during normal business hours on each Swing Line Settlement Date, effect
         a wire transfer of immediately available funds to each Bank of the
         Swing Line Settlement Amount to be paid to such Bank. All funds
         advanced by any Bank as a Swing Line Settling Bank pursuant to this
         Section 2.11(b) shall for all purposes be treated as a Base Rate Loan
         made by such Swing Line Settling Bank to the Borrower, and all funds
         received by any Bank pursuant to this Section 2.11(b) shall for all
         purposes be treated as repayment of amounts owed by the Borrower with
         respect to Base Rate Loans made by such Bank.

                                       22


                  (c) The Administrative Agent may (unless notified to the
         contrary by any Swing Line Settling Bank by 12:00 noon (New York time)
         one (1) Business Day prior to the Settlement Date) assume that each
         Swing Line Settling Bank has made available (or will make available by
         the time specified in Section 2.11(b)) to the Administrative Agent its
         Swing Line Settlement Amount, and the Administrative Agent may (but
         shall not be required to), in reliance upon such assumption, make
         available to each applicable Bank its share (if any) of the aggregate
         Swing Line Settlement Amount. If the Swing Line Settlement Amount of
         such Swing Line Settling Bank is made available to the Administrative
         Agent by such Swing Line Settling Bank on a date after such Swing Line
         Settlement Date, such Swing Line Settling Bank shall pay the
         Administrative 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 annual interest rate paid by the Administrative
         Agent for federal funds acquired by the Administrative Agent during
         each day included in such period times (ii) such Swing Line Settlement
         Amount times (iii) a fraction, the numerator of which is the number of
         days that elapse from and including such Swing Line Settlement Date to
         but not including the date on which such Swing Line Settlement Amount
         shall become immediately available to the Administrative Agent, and the
         denominator of which is 365. Upon payment of such amount such Swing
         Line Settling Bank shall be deemed to have delivered its Swing Line
         Settlement Amount on the Swing Line Settlement Date and shall become
         entitled to interest payable by the Borrower with respect to such Swing
         Line Settling Bank's Swing Line Settlement Amount as if such share were
         delivered on the Swing Line Settlement Date. If such Swing Line
         Settlement Amount is not in fact made available to the Administrative
         Agent by such Swing Line Settling Bank within three (3) Business Days
         of such Swing Line Settlement Date, the Administrative Agent shall be
         entitled to recover such amount from the Borrower, with interest
         thereon at the Base Rate.

                  (d) After any Swing Line Settlement Date, any payment by the
         Borrower of Swing Line Loans hereunder shall be allocated among the
         Banks, in amounts determined so as to provide that after such
         application and the related Swing Line Settlement, the outstanding
         amount of Syndicated Loans of each Bank equals, as nearly as
         practicable, such Bank's Commitment Percentage of the aggregate amount
         of Syndicated Loans.

         SECTION 3.  LETTERS OF CREDIT.

         SECTION 3.1.  LETTER OF CREDIT COMMITMENTS.

                  (a) Subject to the terms and conditions hereof and the receipt
         of a Letter of Credit Application by an Issuing Bank, with a copy to
         the Administrative Agent reflecting the Maximum Drawing Amount of all
         Letters of Credit (including the requested Letter of Credit), such
         Issuing Bank, on behalf of the Banks and in reliance upon the
         representations and warranties of the Borrower contained herein and the
         agreement of the Banks contained in Section 3.1(b) hereof, agrees to
         issue Letters of Credit for the account of the Borrower (which may,
         with such Issuing Bank's consent, incorporate automatic renewals for
         periods of up to twelve (12) months), in such form as may be requested
         from time to time by the Borrower and agreed to by the Issuing Bank;

<PAGE>   29
                                       23


         provided, however, that, after giving effect to such request, the
         aggregate Maximum Drawing Amount of all Letters of Credit issued at any
         time shall not exceed the Total Commitment minus the aggregate
         outstanding amount of the Loans and provided further, that no Letter of
         Credit shall have an expiration date later than the earlier of (i)
         eighteen (18) months after the date of issuance (which may incorporate
         automatic renewals for periods of up to twelve (12) months), or (ii)
         five (5) Business Days prior to the Maturity Date. The letters of
         credit listed in Schedule 3.1(a) issued by Issuing Banks under the
         Existing Credit Agreement shall be Letters of Credit under this
         Agreement.

                  (b) Each Letter of Credit shall be denominated in Dollars.
         Each Bank severally agrees that it shall be absolutely liable, without
         regard to the occurrence of any Default or Event of Default, the
         termination of the Total Commitment pursuant to Section 12.2, or any
         other condition precedent whatsoever, to the extent of such Bank's
         Commitment Percentage to reimburse the Issuing Bank on demand for the
         amount of each draft paid by the Issuing Bank under each Letter of
         Credit to the extent that such amount is not reimbursed by the Borrower
         pursuant to Section 3.2 (such agreement for a Bank being called herein
         the "Letter of Credit Participation" of such Bank). Each Bank agrees
         that its obligation to reimburse the Issuing Bank pursuant to this
         Section 3.1(b) shall not be affected in any way by any circumstance
         other than the gross negligence or willful misconduct of the Issuing
         Bank.

                  (c) Each such reimbursement payment made by a Bank to the
         Issuing Bank shall be treated as the purchase by such Bank of a
         participating interest in the applicable 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 BORROWER. In order to
induce the Issuing Banks to issue, extend and renew each Letter of Credit, the
Borrower hereby agrees to reimburse or pay to each Issuing Bank, with respect to
each Letter of Credit issued, extended or renewed by such Issuing Bank hereunder
as follows:

                  (a) if any draft presented under any Letter of Credit is
         honored by such Issuing Bank or such Issuing Bank otherwise makes
         payment with respect thereto, the sum of (i) the amount paid by such
         Issuing Bank 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 such Issuing Bank in connection with any payment
         made by such Issuing Bank under, or with respect to, such Letter of
         Credit, provided however, if the Borrower does not reimburse such
         Issuing Bank on the Drawdown Date, such amount shall, provided that no
         Event of Default under Section Section 12.1(g) or 12.1(h) has occurred,
         become automatically a Syndicated Loan which is a Base Rate Loan
         advanced hereunder in an amount equal to such sum; and

                  (b) upon the Maturity Date or the acceleration of the
         Reimbursement Obligations with respect to all Letters of Credit in
         accordance with Section 12, an amount equal to the then Maximum Drawing
         Amount of all Letters of Credit shall be paid by the



<PAGE>   30
                                       24


         Borrower to the Administrative Agent to be held as cash collateral for
         the applicable Reimbursement Obligations.

         SECTION 3.3. OBLIGATIONS ABSOLUTE. The Borrower's respective
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 Borrower may have or have had against any Issuing
Bank, any Bank or any beneficiary of a Letter of Credit, and the Borrower
expressly waives any such rights that it may have with respect thereto. The
Borrower further agrees with each Issuing Bank and the Banks that such Issuing
Bank and the Banks (i) shall not be responsible for, and the Borrower's
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 (unless due to the willful misconduct of
such Issuing Bank or any other Bank), or any dispute between or among the
Borrower and 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 Borrower against the beneficiary of any
Letter of Credit or any such transferee, and (ii) 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 except to the extent of their own willful misconduct. The Borrower agrees
that any action taken or omitted by any Issuing Bank or any Bank in good faith
under or in connection with any Letter of Credit and the related drafts and
documents shall be binding upon the Borrower and shall not result in any
liability on the part of such Issuing Bank or any Bank (or their respective
affiliates) to the Borrower. Nothing herein shall constitute a waiver by the
Borrower of any of its rights against any beneficiary of a Letter of Credit.

         SECTION 3.4. RELIANCE BY THE ISSUING BANKS. To the extent not
inconsistent with Section 3.3, each Issuing Bank 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, facsimile, telex or teletype message, statement, order or other
document believed by such Issuing Bank in good faith 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 and other
experts selected by such Issuing Bank.

         SECTION 3.5. NOTICE REGARDING LETTERS OF CREDIT. One (1) Business Day
prior to the issuance of any Letter of Credit or amendments, extensions or
terminations thereof, the applicable Issuing Bank shall notify the
Administrative Agent of the terms of such Letter of Credit, amendment, extension
or termination. On the day of any drawing under any Letter of Credit, such
Issuing Bank shall notify the Administrative Agent of such drawing under any
Letter of Credit.

         SECTION 3.6. LETTER OF CREDIT FEE. The Borrower shall pay a fee (the
"Letter of Credit Fee") equal to the Applicable L/C Rate on the Maximum Drawing
Amount of the Letters of Credit to the Administrative Agent for the account of
the Banks, to be shared pro rata by the Banks in accordance with their
respective Commitment Percentages. The Letter of Credit Fee shall be payable
quarterly in arrears on the first day of each calendar quarter for the quarter
just ended, with the first such payment commencing January 1, 2000, and on the
Maturity Date. In addition,



<PAGE>   31
                                       25



an issuing fee (the "Issuance Fee") with respect to each Letter of Credit to be
agreed upon annually between the Borrower and each Issuing Bank shall be payable
to such Issuing Bank for its account.

         SECTION 4.  COMPETITIVE BID LOANS.

         SECTION 4.1. THE COMPETITIVE BID OPTION. In addition to the Syndicated
Loans made pursuant to Section 2 hereof, the Borrower may request Competitive
Bid Loans pursuant to the terms of this Section 4. The Banks may, but shall have
no obligation to, make such offers and the Borrower may, but shall have no
obligation to, accept such offers in the manner set forth in this Section 4.
Notwithstanding any other provision herein to the contrary, at no time shall the
aggregate principal amount of Competitive Bid Loans outstanding at any time
exceed the Total Commitment minus the sum of (a) the aggregate outstanding
principal amount of Syndicated Loans (including the Swing Loans), plus (b) the
Maximum Drawing Amount of Letters of Credit, outstanding at such time.

         SECTION 4.2.  COMPETITIVE BID LOAN ACCOUNTS:  COMPETITIVE BID NOTES.

                  (a) The obligation of the Borrower to repay the outstanding
         principal amount of any and all Competitive Bid Loans, plus interest at
         the applicable rate accrued thereon, shall be evidenced by this
         Agreement and by individual loan accounts (the "Competitive Bid Loan
         Accounts" and individually, a "Competitive Bid Loan Account")
         maintained by the Administrative Agent on its books for each of the
         Banks, it being the intention of the parties hereto that, except as
         provided for in paragraph (b) of this Section 4.2, the Borrower's
         obligations with respect to Competitive Bid Loans are to be evidenced
         only as stated herein and not by separate promissory notes.

                  (b) Any Bank may at any time, and from time to time, request
         that any Competitive Bid Loans outstanding to such Bank be evidenced by
         a promissory note of the Borrower in substantially the form of Exhibit
         C hereto (each, a "Competitive Bid Note"), dated as of the Effective
         Date and completed with appropriate insertions. One Competitive Bid
         Note shall be payable to the order of each Bank in an amount equal to
         the Total Commitment, and representing the obligation of the Borrower
         to pay such Bank such principal amount or, if less, the outstanding
         principal amount of any and all Competitive Bid Loans made by such
         Bank, plus interest at the applicable Competitive Bid Rate or
         Competitive Bid Margin accrued thereon, as set forth herein. Upon
         execution and delivery by the Borrower of a Competitive Bid Note, the
         Borrower's obligation to repay any and all Competitive Bid Loans made
         to it by such Bank and all interest thereon shall thereafter be
         evidenced by such Competitive Bid Note.

                  (c) The Borrower irrevocably authorizes (i) each Bank to make
         or cause to be made, in connection with a Drawdown Date of any
         Competitive Bid Loan or at the time of receipt of any payment of
         principal on such Bank's Competitive Bid Note in the case of a
         Competitive Bid Note, and (ii) the Administrative Agent to make or
         cause to be made, in connection with a Drawdown Date of any Competitive
         Bid Loan or at the time of receipt of any payment of principal on such
         Bank's Competitive Bid Loan Account in the case of a Competitive Bid
         Loan Account, an appropriate notation on such Bank's




<PAGE>   32
                                       26



         records or on the schedule attached to such Bank's Competitive Bid Note
         or a continuation of such schedule attached thereto, or the
         Administrative Agent's records, as applicable, reflecting the making of
         the Competitive Bid Loan or the receipt of such payment (as the case
         may be) and such Bank may, prior to any transfer of a Competitive Bid
         Note, endorse on the reverse side thereof the outstanding principal
         amount of Competitive Bid Loans evidenced thereby. The outstanding
         amount of the Competitive Bid Loans set forth on such Bank's record or
         the Administrative Agent's records, as applicable, 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 obligations of the
         Borrower hereunder to make payments of principal of or interest on any
         Competitive Bid Loan when due.

         SECTION 4.3. COMPETITIVE BID QUOTE REQUEST; INVITATION FOR COMPETITIVE
BID QUOTES.

                  (a) When the Borrower wishes to request offers to make
         Competitive Bid Loans under this Section 4, it shall transmit to the
         Administrative Agent by telex or facsimile a Competitive Bid Quote
         Request substantially in the form of Exhibit H hereto (a "Competitive
         Bid Quote Request") so as to be received no later than 1:00 p.m. (New
         York time) (x) five (5) Eurodollar Business Days prior to the requested
         Drawdown Date in the case of a LIBOR Competitive Bid Loan (a "LIBOR
         Competitive Bid Loan") or (y) one (1) Business Day prior to the
         requested Drawdown Date in the case of an Absolute Competitive Bid Loan
         (an "Absolute Competitive Bid Loan"), specifying:

                           (i) the requested Drawdown Date (which must be a
                  Eurodollar Business Day in the case of a LIBOR Competitive Bid
                  Loan or a Business Day in the case of an Absolute Competitive
                  Bid Loan);

                           (ii) the aggregate amount of such Competitive Bid
                  Loans, which shall be $10,000,000 or larger multiple of
                  $1,000,000;

                           (iii) the duration of the Interest Period(s)
                  applicable thereto, subject to the provisions of the
                  definition of Interest Period; and

                           (iv) whether the Competitive Bid Quotes requested are
                  for LIBOR Competitive Bid Loans or Absolute Competitive Bid
                  Loans.

         The Borrower may request offers to make Competitive Bid Loans for more
         than one Interest Period in a single Competitive Bid Quote Request. No
         new Competitive Bid Quote Request shall be given until the Borrower has
         notified the Administrative Agent of its acceptance or non-acceptance
         of the Competitive Bid Quotes relating to any outstanding Competitive
         Bid Quote Request.

                  (b) Promptly upon receipt of a Competitive Bid Quote Request,
         the Administrative Agent shall send to the Banks by telecopy or
         facsimile transmission an Invitation for Competitive Bid Quotes
         substantially in the form of Exhibit I hereto, which shall constitute
         an invitation by the Borrower to each Bank to submit Competitive Bid
         Quotes in accordance with this Section 4.


<PAGE>   33
                                       27


         SECTION 4.4. ALTERNATIVE MANNER OF PROCEDURE. If, after receipt by the
Administrative Agent and each of the Banks of a Competitive Bid Quote Request
from the Borrower in accordance with Section 4.3, the Administrative Agent or
any Bank shall be unable to complete any procedure of the auction process
described in Section Section 4.5 through 4.6 (inclusive) due to the inability of
such Person to transmit or receive communications through the means specified
therein, such Person may rely on telephonic notice for the transmission or
receipt of such communications. In any case where such Person shall rely on
telephone transmission or receipt, any communication made by telephone shall, as
soon as possible thereafter, be followed by written confirmation thereof.

         SECTION 4.5. SUBMISSION AND CONTENTS OF COMPETITIVE BID QUOTES.

                  (a) Each Bank may, but shall be under no obligation to, submit
         a Competitive Bid Quote containing an offer or offers to make
         Competitive Bid Loans in response to any Competitive Bid Quote Request.
         Each Competitive Bid Quote must comply with the requirements of this
         Section 4.5 and must be submitted to the Administrative Agent by telex
         or facsimile transmission at its offices as specified in or pursuant to
         Section 22 not later than (x) 2:00 p.m. (New York time) on the fourth
         Eurodollar Business Day prior to the proposed Drawdown Date, in the
         case of a LIBOR Competitive Bid Loan or (y) 10:00 a.m. (New York time)
         on the proposed Drawdown Date, in the case of an Absolute Competitive
         Bid Loan, provided that Competitive Bid Quotes may be submitted by the
         Administrative Agent in its capacity as a Bank only if it submits its
         Competitive Bid Quote to the Borrower not later than (x) one hour prior
         to the deadline for the other Banks, in the case of a LIBOR Competitive
         Bid Loan or (y) 15 minutes prior to the deadline for the other Banks,
         in the case of an Absolute Competitive Bid Loan. Subject to the
         provisions of Section Section 10 and 11 hereof, any Competitive Bid
         Quote so made shall be irrevocable except with the written consent of
         the Administrative Agent given on the instructions of the Borrower.

                  (b) Each Competitive Bid Quote shall be in substantially the
         form of Exhibit J hereto and shall in any case specify:

                           (i)  the proposed Drawdown Date;

                           (ii) the principal amount of the Competitive Bid Loan
                  for which each proposal is being made, which principal amount
                  (w) may be greater than or less than the Commitment of the
                  quoting Bank, (x) must be $5,000,000 or a larger multiple of
                  $1,000,000, (y) may not exceed the aggregate principal amount
                  of Competitive Bid Loans for which offers were requested and
                  (z) may be subject to an aggregate limitation as to the
                  principal amount of Competitive Bid Loans for which offers
                  being made by such quoting Bank may be accepted;

                           (iii) the Interest Period(s) for which Competitive
                  Bid Quotes are being submitted;

                           (iv) in the case of a LIBOR Competitive Bid Loan, the
                  margin above or below the applicable LIBOR Rate (the
                  "Competitive Bid Margin") offered for

                  each such Competitive Bid Loan, expressed as a percentage
                  (specified to the nearest 1/10,000th of 1%) to be added to or
                  subtracted from such LIBOR Rate;

                           (v) in the case of an Absolute Competitive Bid Loan,
                  the rate of interest per annum (specified to the nearest
                  1/10,000th of 1%) (the "Competitive Bid Rate") offered for
                  each such Absolute Competitive Bid Loan; and

                           (vi)  the identity of the quoting Bank.

         A Competitive Bid Quote may include up to five separate offers by the
         quoting Bank with respect to each Interest Period specified in the
         related Invitation for Competitive Bid Quotes.

                  (c)  Any Competitive Bid Quote shall be disregarded if it:

                           (i) is not substantially in the form of Exhibit J
                  hereto;

                           (ii) contains qualifying, conditional or similar
                  language;

                           (iii) proposes terms other than or in addition to
                  those set forth in the applicable Invitation for Competitive
                  Bid Quotes; or

                           (iv) arrives after the time set forth in Section
                  4.5(a) hereof.

         SECTION 4.6. NOTICE TO BORROWER. The Administrative Agent shall
promptly notify the Borrower of the terms (x) of any Competitive Bid Quote
submitted by a Bank that is in accordance with Section 4.5 and (y) of any
Competitive Bid Quote that amends, modifies or is otherwise inconsistent with a
previous Competitive Bid Quote submitted by such Bank with respect to the same
Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall
be disregarded by the Administrative Agent unless such subsequent Competitive
Bid Quote is submitted solely to correct a manifest error in such former
Competitive Bid Quote. The Administrative Agent's notice to the Borrower shall
specify (A) the aggregate principal amount of Competitive Bid Loans for which
offers have been received for each Interest Period specified in the related
Competitive Bid Quote Request, (B) the respective principal amounts and
Competitive Bid Margins or Competitive Bid Rates, as the case may be, so
offered, and the identity of the respective Banks submitting such offers, and
(C) if applicable, limitations on the aggregate principal amount of Competitive
Bid Loans for which offers in any single Competitive Bid Quote may be accepted.

         SECTION 4.7. ACCEPTANCE AND NOTICE BY BORROWER AND ADMINISTRATIVE
AGENT. Not later than 11:00 a.m. (New York time) on (x) the third Eurodollar
Business Day prior to the proposed Drawdown Date, in the case of a LIBOR
Competitive Bid Loan or (y) the proposed Drawdown Date, in the case of an
Absolute Competitive Bid Loan, the Borrower shall notify the Administrative
Agent of its acceptance or non-acceptance of each Competitive Bid Quote in
substantially the form of Exhibit K hereto. The Borrower may accept any
Competitive Bid Quote in whole or in part; provided that:


<PAGE>   35
                                       29


                  (i) the aggregate principal amount of each Competitive Bid
         Loan may not exceed the applicable amount set forth in the related
         Competitive Bid Quote Request;

                  (ii) acceptance of offers may only be made on the basis of
         ascending Competitive Bid Margins or Competitive Bid Rates, as the case
         may be, and

                  (iii) the Borrower may not accept any offer that is described
         in subsection 4.5(c) or that otherwise fails to comply with the
         requirements of this Agreement.

The Administrative Agent shall promptly notify each Bank which submitted a
Competitive Bid Quote of the Borrower's acceptance or non-acceptance thereof. At
the request of any Bank which submitted a Competitive Bid Quote and with the
consent of the Borrower, the Administrative Agent will promptly notify all Banks
which submitted Competitive Bid Quotes of (a) the aggregate principal amount of,
and (b) the range of Competitive Bid Rates or Competitive Bid Margins of, the
accepted Competitive Bid Loans for each requested Interest Period.

         SECTION 4.8. ALLOCATION BY ADMINISTRATIVE AGENT. If offers are made by
two or more Banks with the same Competitive Bid Margin or Competitive Bid Rate,
as the case may be, for a greater aggregate principal amount than the amount in
respect of which offers are accepted for the related Interest Period, the
principal amount of Competitive Bid Loans in respect of which such offers are
accepted shall be allocated by the Administrative Agent among such Banks as
nearly as possible (in such multiples, not less than $1,000,000, as the
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determination by the Administrative Agent of
the amounts of Competitive Bid Loans shall be conclusive in the absence of
manifest error.

         SECTION 4.9. FUNDING OF COMPETITIVE BID LOANS. If, on or prior to the
Drawdown Date of any Competitive Bid Loan, the Total Commitment has not
terminated in full and if, on such Drawdown Date, the applicable conditions of
Section Section 10 and 11 hereof are satisfied, the Bank or Banks whose offers
the Borrower has accepted will fund each Competitive Bid Loan so accepted. Such
Bank or Banks will make such Competitive Bid Loans by crediting the
Administrative Agent for further credit to the Borrower's specified account with
the Administrative Agent, in immediately available funds not later than 1:00
p.m. (New York time) on such Drawdown Date.

         SECTION 4.10. FUNDING LOSSES. If, after acceptance of any Competitive
Bid Quote pursuant to Section 4, the Borrower (i) fails to borrow any
Competitive Bid Loan so accepted on the date specified therefor, or (ii) repays
the outstanding amount of the Competitive Bid Loan prior to the last day of the
Interest Period relating thereto, the Borrower shall indemnify the Bank making
such Competitive Bid Quote or funding such Competitive Bid Loan against any loss
or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Bank to fund or maintain such unborrowed Loans,
including, without limitation compensation as provided in Section 5.8.

         SECTION 4.11. REPAYMENT OF COMPETITIVE BID LOANS; INTEREST. The
principal of each Competitive Bid Loan shall become absolutely due and payable
by the Borrower on the last day



<PAGE>   36
                                       30


of the Interest Period relating thereto, and the Borrower hereby absolutely and
unconditionally promises to pay to the Administrative Agent for the account of
the relevant Banks at or before 1:00 p.m. (New York time) on the last day of the
Interest Periods relating thereto the principal amount of all such Competitive
Bid Loans, plus interest thereon at the applicable rate. The Competitive Bid
Loans shall bear interest at the rate per annum specified in the applicable
Competitive Bid Quotes. Interest on the Competitive Bid Loans shall be payable
(a) on the last day of the applicable Interest Periods, and if any such Interest
Period is longer than three months, also on the last day of the third month
following the commencement of such Interest Period, and (b) on the Maturity Date
for all Loans. Subject to the terms of this Agreement, the Borrower may make
Competitive Bid Quote Requests with respect to new borrowings of any amounts so
repaid prior to the Maturity Date.

         SECTION 5.  PROVISIONS RELATING TO ALL LOANS AND LETTERS OF CREDIT.

         SECTION 5.1.  PAYMENTS.

                  (a) All payments of principal, interest, Reimbursement
         Obligations, fees (other than the Issuance Fee) and any other amounts
         due hereunder or under any of the other Loan Documents shall be made to
         the Administrative Agent at its Head Office in immediately available
         funds by 11:00 a.m. (New York time) on any due date. Subject to the
         provisions of Section 29, if a payment is received by the
         Administrative Agent at or before 1:00 p.m. (New York time) on any
         Business Day, the Administrative Agent shall on the same Business Day
         transfer in immediately available funds, as applicable, to (1) each of
         the Banks, their pro rata portion of such payment in accordance with
         their respective Commitment Percentages, in the case of payments with
         respect to Syndicated Loans and Letters of Credit, (2) MGT in the case
         of payments with respect to Swing Line Loans, and (3) the appropriate
         Bank(s), in the case of payments with respect to Competitive Bid Loans.
         If such payment is received by the Administrative Agent after 1:00 p.m.
         (New York time) on any Business Day, such transfer shall be made by the
         Administrative Agent to the applicable Bank(s) on the next Business
         Day. In the event that the Administrative Agent fails to make such
         transfer to any Bank as set forth above, the Administrative Agent shall
         pay to such Bank 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 such Bank for funds acquired
         by such Bank during each day included in such period, times (ii) the
         amount (A) equal to such Bank's Commitment Percentage of such payment
         in the case of payments under clause (1) above, or (B) of such payment
         to which such Bank is entitled in the case of payments with respect to
         Competitive Bid Loans and Swing Line Loans, times (iii) a fraction, the
         numerator of which is the number of days that elapse from and including
         the date of payment to and including the date on which the amount due
         to such Bank shall become immediately available to such Bank, and the
         denominator of which is 365. A statement of such Bank submitted to the
         applicable Administrative Agent with respect to any amounts owing under
         this paragraph shall be prima facie evidence of the amount due and
         owing to such Bank by the Administrative Agent.

                                       31



                  (b) Each Bank that is not incorporated or organized under the
         laws of the United States of America or a state thereof or the District
         of Columbia (a "Non-U.S. Bank") agrees that, prior to the first date on
         which any payment is due to it hereunder, it will deliver to the
         Borrower and the Administrative Agent two duly completed copies of
         United States Internal Revenue Service Form W-8BEN or W-8ECI or
         successor applicable form, as the case may be, certifying in each case
         that such Non-U.S. Bank is entitled to receive payments under this
         Agreement and the Notes payable to it, without deduction or withholding
         of any United States federal income taxes. Each Non-U.S. Bank that so
         delivers a Form W-8BEN or W-8ECI pursuant to the preceding sentence
         further undertakes to deliver to each of the Borrower and the
         Administrative Agent two further copies of Form W-8BEN or W-8ECI or
         successor applicable form, or other manner of certification, as the
         case may be, on or before the date that any such letter or form expires
         or becomes obsolete or after the occurrence of any event requiring a
         change in the most recent form previously delivered by it to the
         Borrower, and such extensions or renewals thereof as may reasonably be
         requested by the Borrower, certifying in the case of a Form W-8BEN or
         W-8ECI that such Non-U.S. Bank is entitled to receive payments under
         this Agreement and the Notes without deduction or withholding of any
         United States federal income taxes, unless in any such case an event
         (including, without limitation, any change in treaty, law or
         regulation) has occurred prior to the date on which any such delivery
         would otherwise be required which renders all such forms inapplicable
         or which would prevent such Non-U.S. Bank from duly completing and
         delivering any such form with respect to it and such Non-U.S. Bank
         advises the Borrower that it is not capable of receiving payments
         without any deduction or withholding of United States federal income
         tax.

                  (c) The Borrower shall not be required to pay any additional
         amounts to any Non-U.S. Bank in respect of United States Federal
         withholding tax pursuant to Section 17 to the extent that (i) the
         obligation to withhold amounts with respect to United States Federal
         withholding tax existed on the date such Non-U.S. Bank became a party
         to this Agreement or, with respect to payments to a different lending
         office designated by the Non-U.S. Bank as its applicable lending office
         (a "New Lending Office"), the date such Non-U.S. Bank designated such
         New Lending Office with respect to a Loan; provided, however, that this
         clause (i) shall not apply to any transferee or New Lending Office as a
         result of an assignment, transfer or designation made at the request of
         the Borrower; and provided further, however, that this clause (i) shall
         not apply to the extent the indemnity payment or additional amounts any
         transferee, or Bank through a New Lending Office, would be entitled to
         receive without regard to this clause (i) do not exceed the indemnity
         payment or additional amounts that the Person making the assignment or
         transfer to such transferee, or Bank making the designation of such New
         Lending Office, would have been entitled to receive in the absence of
         such assignment, transfer or designation; or (ii) the obligation to pay
         such additional amounts would not have arisen but for a failure by such
         Non-U.S. Bank to comply with the provisions of paragraph (b) above.

                  (d) Notwithstanding the foregoing, each Bank agrees to use
         reasonable efforts (consistent with legal and regulatory restrictions)
         to change its lending office to avoid or to minimize any amounts
         otherwise payable under Section 17 in each case solely if such change



<PAGE>   38
                                       32


         can be made in a manner so that such Bank, in its sole determination,
         suffers no legal, economic or regulatory disadvantage.

         SECTION 5.2.  MANDATORY REPAYMENTS OF THE LOANS.

                  (a) If at any time the sum of the outstanding principal amount
         of the Loans plus the Maximum Drawing Amount of all outstanding Letters
         of Credit exceeds the Total Commitment, whether by reduction of the
         Total Commitment or otherwise, then the Borrower shall immediately pay
         the amount of such excess to the Administrative Agent, (i) for
         application to the Loans, first to Syndicated Loans, then to
         Competitive Bid Loans, subject to Section 5.8, or (ii) if no Loans
         shall be outstanding, to be held by the Administrative Agent for the
         benefit of the Banks as collateral security for such excess Maximum
         Drawing Amount and the Borrower hereby grants a security interest in
         such amount to the Administrative Agent for the benefit of the Banks;
         provided, however, that if the amount of cash collateral held by the
         Administrative Agent pursuant to this Section 5.2(a) exceeds the
         Maximum Drawing Amount required to be collateralized from time to time,
         the Administrative Agent shall return such excess to the Borrower.

                  (b) Payments required pursuant to Section Section 8.4(c) and
         (d) shall be applied in the manner set forth in subsection (a) above.

         SECTION 5.3. COMPUTATIONS. Except as otherwise expressly provided
herein, all computations of interest, Facility Fees, Letter of Credit Fees or
other fees shall be based on a 360-day year and paid for the actual number of
days elapsed, except that computations based on the Administrative Agent's
"prime rate" shall be based on a 365 or 366, as applicable, day year and paid
for the actual number of days elapsed. 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 payment shall be extended to the next succeeding Business Day,
and interest shall accrue during such extension; provided that for any Interest
Period for any Eurodollar Loan if such next succeeding Business Day falls in the
next succeeding calendar month or after the Maturity Date, it shall be deemed to
end on the next preceding Business Day.

         SECTION 5.4. ILLEGALITY; INABILITY TO DETERMINE EURODOLLAR RATE.
Notwithstanding any other provision of this Agreement (other than Section 5.10),
if (a) the introduction of, any change in, or any change in the interpretation
of, any law or regulation applicable to any Bank or the Administrative Agent
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 Administrative Agent to perform its obligations in respect of any Eurodollar
Loans, or (b) if any Bank or the Administrative Agent, as applicable, 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 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 Administrative Agent in any Eurodollar interbank market, or (iii) the
Eurodollar Rate does not or will not accurately reflect the cost to the Bank or
the Administrative Agent of obtaining or maintaining the Eurodollar Loans during
any Interest Period, then such Bank or the Administrative Agent shall promptly
give telephonic, telex or cable notice of such determination to the Borrower
<PAGE>   39

                                       33


(which notice shall be conclusive and binding upon the Borrower). Upon such
notification by the Bank or the Administrative Agent, the obligation of the
Banks and the Administrative Agent to make Eurodollar Loans shall be suspended
until the Banks or the Administrative Agent, as the case may be, determine that
such circumstances no longer exist, and to the extent permitted by law 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 to such former Eurodollar Loans.

         SECTION 5.5. 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:

                  (a) subject such Bank to any tax, levy, impost, duty, charge,
         fee, deduction or withholding of any nature with respect to this
         Agreement, the other Loan Documents, such Bank's Commitment or the
         Loans (other than taxes based upon or measured by the income or profits
         of such Bank imposed by the jurisdiction of its incorporation or
         organization, or the location of its lending office); or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits of such Bank imposed by the
         jurisdiction of its incorporation or organization, or the location of
         its lending office) of payments to such Bank of the principal or of the
         interest on any Loans or any other amounts payable to such Bank under
         this Agreement or the other Loan Documents; or

                  (c) except as provided in Section 5.6 or as otherwise
         reflected in the Base Rate, the Eurodollar Rate, or the applicable rate
         for Competitive Bid Loans, impose or increase or render applicable
         (other than to the extent specifically provided for elsewhere in this
         Agreement) any special deposit, reserve, assessment, liquidity, capital
         adequacy or other similar requirements (whether or not having the force
         of law) against assets held by, or deposits in or for the account of,
         or loans by, or commitments of, an office of any Bank with respect to
         this Agreement, the other Loan Documents, such Bank's Commitment or the
         Loans; or

                  (d) impose on such Bank any other conditions or requirements
         with respect to this Agreement, the other Loan Documents, the Loans,
         such Bank's Commitment or any class of loans or commitments of which
         any of the Loans or such Bank's Commitment 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
                  or such Bank's Commitment or issuing or participating in
                  Letters of Credit;
<PAGE>   40
                                       34


                           (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 the Reimbursement Obligations;
                  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 Borrower
                  hereunder,

                  then, and in each such case, the Borrower will, upon demand
         made by such Bank at any time and from time to time as often as the
         occasion therefore may arise (which demand shall be accompanied by a
         statement setting forth the basis of such demand which shall be
         conclusive absent manifest error), pay such reasonable additional
         amounts as will be sufficient to compensate such Bank for such
         additional costs, reduction, payment or foregone interest or other sum.

         SECTION 5.6. CAPITAL ADEQUACY. If any Bank shall have determined that,
after the date hereof, the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change in any such law, rule, or regulation,
or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of such Bank (or any corporation controlling such
Bank) as a consequence of such Bank's obligations hereunder to a level below
that which such Bank (or any corporation controlling such Bank) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank, the Borrower shall pay to such Bank such additional amount or
amounts as will, in such Bank's reasonable determination, fairly compensate such
Bank (or any corporation controlling such Bank) for such reduction. Each Bank
shall allocate such cost increases among its customers in good faith and on an
equitable basis.

         SECTION 5.7. CERTIFICATE. A certificate setting forth the additional
amounts payable pursuant to Section 5.5 or Section 5.6 and a reasonable
explanation of such amounts which are due, submitted by any Bank to the
Borrower, shall be conclusive, absent manifest error, that such amounts are due
and owing.

         SECTION 5.8. EURODOLLAR AND COMPETITIVE BID INDEMNITY. The Borrower
agrees to indemnify the Banks and the Administrative Agent and to hold them
harmless from and against any reasonable loss, cost or expense that any such
Bank and the Administrative Agent may sustain or incur as a consequence of (a)
the default by the Borrower in payment of the principal amount of or any
interest on any Eurodollar Loans or Competitive Bid Loans as and when due and
payable, including any such loss or expense arising from interest or fees
payable by any Bank or the Administrative Agent to lenders of funds obtained by
it in order to maintain its Eurodollar Loans or Competitive Bid Loans, (b) the
default by the Borrower in making a borrowing of a




<PAGE>   41
                                       35



Eurodollar Loan or Competitive Bid Loan or conversion of a Eurodollar Loan or a
prepayment of a Eurodollar or Competitive Bid Loan other than pursuant to
Section 2.5(b) after the Borrower has given (or is deemed to have given) a
Syndicated Loan Request, a notice pursuant to Section 2.7 or a Notice of
Acceptance/Rejection of Competitive Bid Quote(s), or a notice pursuant to
Section 2.10, and (c) the making of any payment of a Eurodollar Loan or
Competitive Bid Loan, or the making of any conversion of any Eurodollar Loan to
a Base Rate Loan on a day that is not the last day of the applicable Interest
Period with respect thereto. Such loss, cost, or reasonable expense shall
include an amount equal to the excess, if any, as reasonably determined by each
Bank of (i) its cost of obtaining the funds for (A) the Eurodollar Loan being
paid, prepaid, converted, not converted, reallocated, or not borrowed, as the
case may be (based on the Eurodollar Rate), or (B) the Competitive Bid Loan
being paid, prepaid, or not borrowed, as the case may be (based on the
applicable interest rate) for the period from the date of such payment,
prepayment, conversion, or failure to borrow or convert, as the case may be, to
the last day of the Interest Period for such Loan (or, in the case of a failure
to borrow, the Interest Period for the Loan which would have commenced on the
date of such failure to borrow) over (ii) the amount of interest (as reasonably
determined by such Bank) that would be realized by such Bank in reemploying the
funds so paid, prepaid, converted, or not borrowed, converted, or prepaid for
such period or Interest Period, as the case may be, which determinations shall
be conclusive absent manifest error.

         SECTION 5.9. 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 compounded monthly and payable on demand at a rate per annum equal to
the Base Rate plus 2%, until such amount shall be paid in full (after as well as
before judgment).

         SECTION 5.10. INTEREST LIMITATION. Notwithstanding any other term of
this Agreement or the Notes, any other Loan Document 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 the Notes 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 by such
Bank under applicable laws (including, to the extent applicable, the provisions
of Section 5197 of the Revised Statutes of the United States of America, as
amended, and 12 U.S.C. Section 85, as amended).

         SECTION 5.11. REASONABLE EFFORTS TO MITIGATE. Each Bank agrees that as
promptly as practicable after it becomes aware of the occurrence of an event or
the existence of a condition that would cause it to be affected under Section
Section 5.4, 5.5 or 5.6, such Bank will give notice thereof to the Borrower,
with a copy to the Administrative Agent and, to the extent so requested by the
Borrower and not inconsistent with such Bank's internal policies, such Bank
shall use reasonable efforts and take such actions as are reasonably appropriate
if as a result thereof the additional moneys which would otherwise be required
to be paid to such Bank pursuant to such sections would be materially reduced,
or the illegality or other adverse circumstances which would otherwise require a
conversion of such Loans or result in the inability to make such Loans pursuant
to such sections would cease to exist, and in each case if, as determined by
such Bank in its sole discretion, the taking of such actions would not adversely
affect such Loans or such Bank or otherwise be disadvantageous to such Bank.

                                       36



         SECTION 5.12. REPLACEMENT OF BANKS. If any Bank (an "Affected Bank")
(i) makes demand upon the Borrower for (or if the Borrower is otherwise required
to pay) amounts pursuant to Section Section 5.5 or 5.6, (ii) is unable to make
or maintain Eurodollar Loans as a result of a condition described in Section 5.4
or (iii) defaults in its obligation to make Loans or to participate in Letters
of Credit in accordance with the terms of this Agreement (such Bank being
referred to as a "Defaulting Bank"), the Borrower may, within 90 days of receipt
of such demand, notice (or the occurrence of such other event causing the
Borrower to be required to pay such compensation or causing Section 5.4 to be
applicable), or default, as the case may be, by notice (a "Replacement Notice")
in writing to the Administrative Agent and such Affected Bank (A) request the
Affected Bank to cooperate with the Borrower in obtaining a replacement bank
satisfactory to the Administrative Agent and the Borrower (the "Replacement
Bank") as provided herein, but none of such Banks shall be under an obligation
to find a Replacement Bank; (B) request the non-Affected Banks to acquire and
assume all of the Affected Bank's Loans and Commitment, and to participate in
Letters of Credit 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 Administrative 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, and to participate in Letters
of Credit then such Affected Bank shall, so long as no Event of Default shall
have occurred and be continuing, assign, in accordance with Section 20, all of
its Commitment, Loans, Notes and other rights and obligations under this
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 (x) 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 (y) prior to any such assignment, the Borrower shall have paid to such
Affected Bank all amounts properly demanded and unreimbursed under Section
Section 5.5, 5.6 and 5.8. Upon the effective date of such assignment, the
Borrower shall issue replacement Notes to such Replacement Bank and/or
non-Affected Banks, as the case may be, and such Replacement Bank shall become a
"Bank" for all purposes under this Agreement and the other Loan Documents.

         SECTION 5.13. ADVANCES BY ADMINISTRATIVE AGENT. The Administrative
Agent may (unless earlier notified to the contrary by any Bank by 12:00 noon
(New York time) one (1) Business Day prior to any Drawdown Date) assume that
each Bank has made available (or will before the end of such Business Day make
available) to the Administrative Agent the amount of such Bank's Commitment
Percentage with respect to the Loans (or, in the case of Competitive Bid Loans,
the amount of such Bank's accepted offers of such Loans, if any) to be made on
such Drawdown Date, and the Administrative Agent may (but shall not be required
to), in reliance upon such assumption, make available to the Borrower a
corresponding amount. If any Bank makes such amount available to the
Administrative Agent on a date after such Drawdown Date, such Bank shall pay the
Administrative 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 annual interest rate paid by the Administrative Agent for
federal funds acquired by the Administrative Agent during each day included in
such period times (ii) the amount equal to such Bank's Commitment Percentage of
such Syndicated Loan (or, in the case of Competitive



<PAGE>   43
                                       37



Bid Loans and Swing Line Loans, the amount of such Bank's accepted offer of such
Competitive Bid Loans, if any, and portion of such Swing Line Loans) times (iii)
a fraction, the numerator of which is the number of days that elapse from and
including such Drawdown Date to but not including the date on which the amount
equal to such Bank's Commitment Percentage of such Loans, or the amount of such
Bank's accepted offers of such Competitive Bid Loans, if any, and portion of
Swing Line Loans, shall become immediately available to the Administrative
Agent, and the denominator of which is 365. A statement of the Administrative
Agent submitted to such Bank with respect to any amounts owing under this
paragraph shall be prima facie evidence of the amount due and owing to the
Administrative Agent by such Bank. If such amount is not in fact made available
to the Administrative Agent by such Bank within three (3) Business Days of such
Drawdown Date, the Administrative Agent shall be entitled to recover such amount
from such Borrower, with interest thereon at the applicable rate per annum.

         SECTION 6. REPRESENTATIONS AND WARRANTIES. The Borrower (and each of
the Guarantors, where applicable) represents and warrants to the Banks that:

         SECTION 6.1.  CORPORATE AUTHORITY.

                  (a) INCORPORATION; GOOD STANDING. The Borrower and each of its
         Subsidiaries (i) is duly organized, validly existing and in good
         standing under the laws of its respective jurisdiction of formation,
         (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 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 the Borrower and its
         Subsidiaries as a whole.

                  (b) AUTHORIZATION. The execution, delivery and performance of
         its Loan Documents and the transactions contemplated hereby and thereby
         (i) are within the corporate authority of the Borrower and each of the
         Guarantors, (ii) have been duly authorized by all necessary corporate
         proceedings on the part of each of the Borrower and the Guarantors,
         (iii) do not conflict with or result in any breach or contravention of
         any provision of law, statute, rule or regulation to which any of the
         Borrower or the Guarantors or any of their Subsidiaries is subject or
         any judgment, order, writ, injunction, license or permit applicable to
         the Borrower, any of the Guarantors or any of their Subsidiaries so as
         to materially adversely affect the assets, business or any activity of
         the Borrower, the Guarantors and their Subsidiaries as a whole, and
         (iv) do not conflict with any provision of the corporate charter or
         bylaws of the Borrower, the Guarantors or any Subsidiary or any
         agreement or other instrument binding upon the Borrower, the Guarantors
         or any of their Subsidiaries.

                  (c) ENFORCEABILITY. The execution, delivery and performance of
         the Loan Documents by the Borrower and the Guarantors will result in
         valid and legally binding obligations of the Borrower and the
         Guarantors enforceable against them 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




<PAGE>   44
                                       38


         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 6.2. GOVERNMENTAL AND OTHER APPROVALS. The execution, delivery
and performance of the Loan Documents by the Borrower and the Guarantors and the
consummation by the Borrower and the Guarantors of the transactions contemplated
hereby and thereby do not require any approval or consent of, or filing with,
any governmental agency or authority or other third party other than those
already obtained and those required after the date hereof in connection with the
Borrower's and its Subsidiaries' performance of their covenants contained in
Section Section 7, 8 and 9 hereof.

         SECTION 6.3. TITLE TO PROPERTIES; LEASES. The Borrower and its
Subsidiaries own all of the assets reflected in the consolidated balance sheet
as at the Interim Balance Sheet Date or acquired since that date (except
property and assets operated under capital leases or sold or otherwise disposed
of in the ordinary course of business since that date), subject to no mortgages,
Capitalized Leases, conditional sales agreements, title retention agreements,
liens or other encumbrances except Permitted Liens.

         SECTION 6.4.  FINANCIAL STATEMENTS; SOLVENCY.

                  (a) There have been furnished to the Banks consolidated
         balance sheets of the Borrower and its Subsidiaries dated the Balance
         Sheet Date and consolidated statements of operations for the fiscal
         periods then ended, certified by the Accountants. In addition, there
         have been furnished to the Banks consolidated balance sheets of the
         Borrower and its Subsidiaries dated the Interim Balance Sheet Date and
         the related consolidated statements of operation for the fiscal quarter
         ending on the Interim Balance Sheet Date. All said balance sheets and
         statements of operations have been prepared in accordance with GAAP
         (but, in the case of any of such financial statements which are
         unaudited, only to the extent GAAP is applicable to interim unaudited
         reports), fairly present the financial condition of the Borrower and
         its Subsidiaries on a consolidated basis as at the close of business on
         the dates thereof and the results of operations for the periods then
         ended, subject, in the case of unaudited interim financial statements,
         to changes resulting from audit and normal year-end adjustments and to
         the absence of complete footnotes. There are no contingent liabilities
         of the Borrower and its Subsidiaries involving material amounts, known
         to the officers of the Borrower which have not been disclosed in said
         balance sheets and the related notes thereto or otherwise in writing to
         the Banks.

                  (b) The Borrower and its Subsidiaries on a consolidated basis
         (both before and after giving effect to the transactions contemplated
         by this Agreement) are 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
         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 6.5. NO MATERIAL CHANGES, ETC. Since the Interim Balance Sheet
Date, there have occurred no material adverse changes in the consolidated
financial condition, business, assets or



<PAGE>   45
                                       39


liabilities (contingent or otherwise) of the Borrower and its Subsidiaries,
taken together, as shown on or reflected in the consolidated balance sheets of
the Borrower and its Subsidiaries as at the Interim Balance Sheet Date, or the
consolidated statements of income for the period then ended other than changes
in the ordinary course of business which have not had any material adverse
effect either individually or in the aggregate on the financial condition,
business, assets or liabilities (contingent or otherwise) of the Borrower and
its Subsidiaries, taken together. Since the Interim Balance Sheet Date, there
have not been any Distributions other than as permitted by Section 8.5 hereof.

         SECTION 6.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. The Borrower and
each of its Subsidiaries possess all franchises, patents, copyrights,
trademarks, trade names, licenses and permits, and rights in respect of the
foregoing, adequate for the conduct of their business substantially as now
conducted (other than those the absence of which would not have a material
adverse effect on the business, operations or financial condition of the
Borrower and its Subsidiaries as a whole) without known conflict with any rights
of others other than a conflict which would not have a material adverse effect
on the financial condition, business or assets of the Borrower and its
Subsidiaries as a whole.

         SECTION 6.7. LITIGATION. Except as set forth on Schedule 6.7 or in the
Disclosure Documents, there are no actions, suits, proceedings or investigations
of any kind pending or, to the knowledge of the Borrower or any of its
Subsidiaries, threatened against the Borrower or any of its Subsidiaries before
any court, tribunal or administrative agency or board which, either in any case
or in the aggregate, could reasonably be expected to have a material adverse
effect on the financial condition, business, or assets of the Borrower and its
Subsidiaries, considered as a whole, or materially impair the right of the
Borrower and its Subsidiaries, considered 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 to which the Borrower or any of its Subsidiaries is a
party, or any action taken or to be taken pursuant hereto or thereto.

         SECTION 6.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower
nor any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Borrower's or such Subsidiary's officers has or could reasonably
be expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Borrower and its Subsidiaries, considered
as a whole. Neither the Borrower nor any of its Subsidiaries is a party to any
contract or agreement which in the judgment of the Borrower's or its
Subsidiary's officers has or could reasonably be expected to have any materially
adverse effect on the financial condition, business or assets of the Borrower
and its Subsidiaries, considered as a whole, except as otherwise reflected in
adequate reserves as required by GAAP.

         SECTION 6.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the
Borrower nor any of its Subsidiaries is (a) violating any provision of its
charter documents or by-laws or (b) violating any agreement or instrument to
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,



<PAGE>   46
                                       40



license, rule or regulation, in a manner which could (in the case of such
agreements or such instruments) reasonably be expected to result in the
imposition of substantial penalties or materially and adversely affect the
financial condition, business or assets of the Borrower and its Subsidiaries,
considered as a whole.

         SECTION 6.10. TAX STATUS. The Borrower and its Subsidiaries have filed
all federal, state, provincial and territorial income and all other tax returns,
reports and declarations (or obtained extensions with respect thereto) required
by applicable law to be filed by them (unless and only to the extent that the
Borrower or such Subsidiary has set aside on its books provisions reasonably
adequate for the payment of all unpaid and unreported taxes as required by
GAAP); and have paid all taxes and other governmental assessments and charges
(other than taxes, assessments and other governmental charges imposed by
jurisdictions other than the United States, Canada or any political subdivision
thereof which in the aggregate are not material to the financial condition,
business or assets of the Borrower or such Subsidiary on an individual basis or
of the Borrower and its Subsidiaries on a consolidated basis) 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, as required by
GAAP, 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. Except to the extent contested in the
manner permitted in the preceding sentence, there are no unpaid taxes in any
material amount claimed by the taxing authority of any jurisdiction to be due
and owing by the Borrower or any Subsidiary, nor do the officers of the Borrower
or any of its Subsidiaries know of any basis for any such claim.

         SECTION 6.11. NO EVENT OF DEFAULT. No (a) Default or Event of Default
has occurred hereunder and is continuing, and (b) no "Default" or "Event of
Default" (as defined in the 364 Day Facility or the European Credit Facilities,
respectively) under the 364 Day Facility or the European Credit Facilities,
respectively, has occurred and is continuing, or would be created by the
incurrence of Indebtedness under this Agreement.

         SECTION 6.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the
Borrower nor any of its Subsidiaries 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.

         SECTION 6.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except as permitted
by Section 8.2 of this Agreement, there is no Indebtedness senior to the
Obligations, and there is no effective 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 the Borrower or any of its Subsidiaries
or right thereunder.

                                       41



         SECTION 6.14.  EMPLOYEE BENEFIT PLANS.

                  SECTION 6.14.1. IN GENERAL. Each Employee Benefit Plan has
         been maintained and operated in compliance in all material respects
         with the provisions of ERISA and/or all Applicable Canadian Pension
         Legislation, as applicable, and, to the extent applicable, the Code,
         including but not limited to the provisions thereunder respecting
         prohibited transactions. Promptly upon the request of any Bank or the
         Administrative Agent, the Borrower will furnish to the Administrative
         Agent the most recently completed annual report, Form 5500, with all
         required attachments, and actuarial statement required to be submitted
         under Section 103(d) of ERISA, with respect to each Guaranteed Pension
         Plan.

                  SECTION 6.14.2. TERMINABILITY OF WELFARE PLANS. Under each
         Employee Benefit Plan which is an employee welfare benefit plan within
         the meaning of Section 3(1) or Section 3(2)(B) of ERISA, no benefits
         are due unless the event giving rise to the benefit entitlement occurs
         prior to plan termination (except as required by Title I, Part 6 of
         ERISA) . The Borrower or an ERISA Affiliate, as appropriate, 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
         the Borrower or such ERISA Affiliate without liability to any Person.

                  SECTION 6.14.3. GUARANTEED PENSION PLANS. 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. No liability to the PBGC (other than required
         insurance premiums, all of which have been paid) has been incurred by
         the Borrower or any ERISA Affiliate with respect to any Guaranteed
         Pension Plan (other than Terminated Plans) and there has not been any
         ERISA Reportable Event, or any other event or condition which presents
         a material risk of termination of any Guaranteed Pension Plan by the
         PBGC. Other than with respect to the Terminated Plans, 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.

                  SECTION 6.14.4. MULTIEMPLOYER PLANS. Neither the 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. Neither the 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 that any Multiemployer Plan intends to terminate or has
         been terminated under Section 4041A of ERISA.

         SECTION 6.15. ENVIRONMENTAL COMPLIANCE. The Borrower and its
Subsidiaries have taken all necessary steps to investigate the past and present
condition and usage of the Real Property and



<PAGE>   48
                                       42



the operations conducted by the Borrower and its Subsidiaries and, based upon
such diligent investigation, have determined that, except as set forth on
Schedule 6.15 or in the Disclosure Documents:

                  (a) Neither the Borrower, its Subsidiaries, nor any operator
         of their 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 the Resource Conservation and Recovery Act
         ("RCRA"), the Comprehensive Environmental Response, Compensation and
         Liability Act of 1980 as amended ("CERCLA"), the Superfund Amendments
         and Reauthorization Act of 1986 ("SARA"), the Federal Clean Water Act,
         the Federal Clean Air Act, the Toxic Substances Control Act, or any
         applicable international, federal, state, provincial, territorial or
         local statute, regulation, ordinance, order or decree relating to
         health, safety, waste transportation or disposal, or the environment
         (the "Environmental Laws"), which violation, individually or in the
         aggregate, would have a material adverse effect on the business, assets
         or financial condition of the Borrower and its Subsidiaries on a
         consolidated basis.

                  (b) Except with respect to any such matters which individually
         or in the aggregate would not reasonably be expected to have a material
         adverse effect on the business, assets or financial condition of the
         Borrower and its Subsidiaries on a consolidated basis, neither the
         Borrower nor any of its Subsidiaries has received notice from any third
         party including, without limitation: any federal, state, provincial,
         territorial or local governmental authority, (i) that any one of them
         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, excluding household hazardous waste ("Hazardous
         Substances"), which any one of them has generated, transported or
         disposed of, has been found at any site at which a federal, state,
         provincial, territorial or local agency or other third party has
         conducted or has ordered that the Borrower or any of its Subsidiaries
         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) (i) No portion of the Real Property or other assets of the
         Borrower and its Subsidiaries has been used for the handling,
         processing, storage or disposal of Hazardous Substances except in

         the Real Property or other assets of the Borrower and its Subsidiaries,
         no Hazardous Substances have been generated or are being used on such
         properties except in accordance with applicable Environmental Laws,
         except for occurrences that would not have a material adverse effect on
         the business, assets or financial condition of the Borrower and its
         Subsidiaries on a consolidated basis; (iii) there have been no
         unpermitted Releases or threatened Releases of Hazardous Substances on,
         upon, into or from the Real Property or other assets of the Borrower or

         on the value of such properties; (iv) to the best of the Borrower's and
         its Subsidiaries' knowledge, there have been no Releases on, upon, from
         or into any real property in the vicinity of the Real Property or other
         assets of the Borrower or its Subsidiaries which, through soil or
         groundwater contamination, may have come to be located on, and which
         would reasonably be expected to have a material adverse effect on the
         value of, such properties; and (v) in addition, any Hazardous
         Substances that have been generated on the Real Property or other
         assets of the Borrower or its Subsidiaries 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 have been and are, to the best
         of the Borrower's and its Subsidiaries' knowledge, operating in
         compliance with such permits and applicable Environmental Laws.

                  (d) None of the Real Property or other assets of the Borrower
         or its Subsidiaries or any of the stock (or assets) being acquired with
         proceeds of Loans 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 6.16. TRUE COPIES OF CHARTER AND OTHER DOCUMENTS. Each of the
Borrower and the Guarantors has furnished the Administrative Agent as of the
Effective Date, true and complete copies of (a) all charter and other
incorporation documents (together with any amendments thereto) and (b) by-laws
(together with any amendments thereto).

         SECTION 6.17. DISCLOSURE. No representation or warranty made by the
Borrower or any Guarantor in this Agreement or in any agreement, instrument,
document, certificate, statement or letter furnished to the Banks or the
Administrative Agent by or on behalf of or at the request of the Borrower and
the Guarantors in connection with any of the transactions contemplated by the
Loan Documents contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained
therein not misleading in light of the circumstances in which they are made.

         SECTION 6.18. PERMITS AND GOVERNMENTAL AUTHORITY. All permits (other
than those the absence of which would not have a material adverse effect on the
business, operations or financial condition of the Borrower and its Subsidiaries
as a whole) required for the construction and operation of all landfills
currently owned or operated by the Borrower or any of its Subsidiaries have been
obtained and remain in full force and effect and are not subject to any appeals
or further proceedings or to any unsatisfied conditions that may allow material




<PAGE>   50
                                       44


modification or revocation. Neither the Borrower nor any of its Subsidiaries,
nor, to the knowledge of the Borrower and its Subsidiaries, the holder of such
permits is in violation of any such permits, except for any violation which
would not have a material adverse effect on the business, operations or
financial condition of the Borrower and its Subsidiaries as a whole.

         SECTION 6.19. YEAR 2000 COMPLIANCE. The Borrower and its Subsidiaries
have reviewed the areas within their businesses 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 Compliance Issue. Based upon such review, the
Borrower reasonably believes that the Year 2000 Compliance Issue will not have
any material adverse effect on the business, operations or financial condition
of the Borrower and its Subsidiaries as a whole.

         SECTION 7. AFFIRMATIVE COVENANTS OF THE BORROWER. The Borrower agrees
that, so long as any Obligation or any Letter of Credit is outstanding or the
Banks have any obligation to make Loans, or any Issuing Bank has any obligation
to issue, extend or renew any Letters of Credit hereunder, or the Banks have any
obligations to reimburse any Issuing Bank for drawings honored under any Letter
of Credit, it shall, and shall cause its Subsidiaries to, comply with the
following covenants:

         SECTION 7.1. PUNCTUAL PAYMENT. The Borrower 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 Agreement
and the other Loan Documents, all in accordance with the terms of this Agreement
and such other Loan Documents.

         SECTION 7.2. MAINTENANCE OF U.S. OFFICE. The Borrower will maintain its
chief executive offices at Houston, Texas, or at such other place in the United
States of America as the Borrower shall designate upon 30 days' prior written
notice to the Administrative Agent.

         SECTION 7.3. RECORDS AND ACCOUNTS. The Borrower will, and will cause
each of its Subsidiaries to, keep true and accurate records and books of account
in which full, true and correct entries will be made in accordance with GAAP and
with the requirements of all regulatory authorities and maintain adequate
accounts and reserves for all taxes (including income taxes), depreciation,
depletion, obsolescence and amortization of its properties, all other
contingencies, and all other proper reserves.

         SECTION 7.4. FINANCIAL STATEMENTS, CERTIFICATES AND INFORMATION. The
Borrower will deliver to the Banks:

                  (a) as soon as practicable, but, in any event not later than
         92 days after the end of each fiscal year of the Borrower, the
         consolidated balance sheet of the Borrower and its Subsidiaries as at
         the end of such year, consolidated statements of cash flows, and the
         related consolidated statements of operations, each setting forth in
         comparative form the figures for the previous fiscal year, all such
         consolidated financial statements to be in reasonable detail, prepared,
         in accordance with GAAP and, with respect to the consolidated financial
         statements, certified by PricewaterhouseCoopers LLP or Arthur Andersen
         LLP or by other independent auditors selected by the Borrower and
         reasonably satisfactory to the Banks (the "Accountants"). In addition,
         simultaneously therewith, the



<PAGE>   51
                                       45



         Borrower shall provide the Banks with a written statement from such
         Accountants to the effect that they have read a copy of this Agreement,
         and that, in making the examination necessary to said certification,
         they have obtained no knowledge of any Default or Event of Default, or,
         if such 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;

                  (b) as soon as practicable, but in any event not later than 47
         days after the end of each of the first three fiscal quarters of each
         fiscal year of the Borrower, copies of the consolidated balance sheet
         and statement of operations of the Borrower and its Subsidiaries as at
         the end of such quarter, subject to year-end adjustments, and the
         related consolidated statement of cash flows, all in reasonable detail
         and prepared in accordance with GAAP (to the extent GAAP is applicable
         to interim unaudited financial statements) with a certification by the
         principal financial or accounting officer of the Borrower (the "CFO or
         the CAO") that the consolidated financial statements are prepared in
         accordance with GAAP (to the extent GAAP is applicable to interim
         unaudited financial statements) and fairly present the consolidated
         financial condition of the Borrower and its Subsidiaries on a
         consolidated basis as at the close of business on the date thereof and
         the results of operations for the period then ended, it being
         understood that no such statement need be accompanied by complete
         footnotes;

                  (c) simultaneously with the delivery of the financial
         statements referred to in (a) and (b) above, a certificate in the form
         of Exhibit F hereto (the "Compliance Certificate") signed by the CFO or
         the CAO or the Borrower's corporate treasurer, stating that the
         Borrower and its Subsidiaries are in compliance with the covenants
         contained in Section Section 7, 8 and 9 hereof as of the end of the
         applicable period and setting forth in reasonable detail computations
         evidencing such compliance with respect to the covenants contained in
         Section Section 8.1(d), 8.3, 8.4, 8.5, and 9 hereof and that no Default
         or Event of Default exists, provided that if the Borrower shall at the
         time of issuance of such Compliance Certificate or at any other time
         obtain knowledge of any Default or Event of Default, the Borrower shall
         include in such certificate or otherwise deliver forthwith to the Banks
         a certificate specifying the nature and period of existence thereof and
         what action the Borrower proposes to take with respect thereto;

                  (d) 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 Borrower's
         and its Subsidiaries' stockholders generally; and

                  (e) from time to time such other financial data and other
         information as the Banks may reasonably request.

         The Borrower hereby authorizes each Bank to disclose any information
obtained pursuant to this Agreement to all appropriate governmental regulatory
authorities where required by law; provided, however, 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 Borrower has or may have under the
federal Right to Financial Privacy Act of 1978, as in effect from time to time,
except as to matters specifically permitted therein.

                                       46



         SECTION 7.5. EXISTENCE AND CONDUCT OF BUSINESS. The Borrower will, and
will cause each Subsidiary, to do or cause to be done all things necessary to
preserve and keep in full force and effect its existence, rights and franchises;
and effect and maintain its foreign qualifications (except where the failure of
the Borrower or any Subsidiary to remain so qualified would not materially
adversely impair the financial condition, business or assets of the Borrower and
its Subsidiaries on a consolidated basis), licensing, domestication or
authorization except as terminated by its Board of Directors in the exercise of
its reasonable judgment; provided that such termination would not have a
material adverse effect on the financial condition, business or assets of the
Borrower and its Subsidiaries on a consolidated basis. The Borrower will not,
and will cause its Subsidiaries not to, become obligated under any contract or
binding arrangement which, at the time it was entered into, would materially
adversely impair the financial condition, business or assets of the Borrower and
its Subsidiaries, on a consolidated basis. The Borrower will, and will cause
each Subsidiary to, continue to engage primarily in the businesses now conducted
by it and in related businesses.

         SECTION 7.6. MAINTENANCE OF PROPERTIES. The Borrower will, and will
cause its Subsidiaries to, 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 (ordinary wear and tear excepted) and supplied with all
necessary equipment and cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Borrower and its Subsidiaries 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 section shall prevent the
Borrower or any of its Subsidiaries from discontinuing the operation and
maintenance of any of its properties if such discontinuance is, in the judgment
of the Borrower or such Subsidiary, desirable in the conduct of its or their
business and which does not in the aggregate materially adversely affect the
financial condition, business or assets of the Borrower and its Subsidiaries on
a consolidated basis.

         SECTION 7.7. INSURANCE. The Borrower will, and will cause its
Subsidiaries to, 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 Borrower and its Subsidiaries, in amounts substantially
similar to the existing coverage policies maintained by the Borrower and its
Subsidiaries, copies of which have been provided to the Administrative Agent. In
addition, the Borrower will furnish from time to time, upon any Bank's request,
a summary of the insurance coverage of the Borrower and its Subsidiaries, which
summary shall be in form and substance satisfactory to the Banks and, if
requested by any of the Banks, will furnish to the Administrative Agent and such
Bank copies of the applicable policies.

         SECTION 7.8. TAXES. The Borrower will, and will cause its Subsidiaries
to, 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
jurisdictions other than the United States, Canada or any political subdivision
thereof, which in the aggregate are not material to the business, financial
conditions, or assets of the Borrower and its Subsidiaries on a consolidated
basis) imposed upon



<PAGE>   53
                                       47



it and its real properties, sales and activities, or any 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 of its
property; 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 the Borrower or such
Subsidiary shall have set aside on its books adequate reserves with respect
thereto as required by GAAP; and provided, further, that the Borrower or such
Subsidiary 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 7.9. INSPECTION OF PROPERTIES, BOOKS AND CONTRACTS. The
Borrower will, and will cause its Subsidiaries to, permit the Administrative
Agent or any Bank or any of their designated representatives, upon reasonable
notice, to visit and inspect any of the properties of the Borrower and its
Subsidiaries, to examine the books of account of the Borrower and its
Subsidiaries, or contracts (and to make copies thereof and extracts therefrom),
and to discuss the affairs, finances and accounts of the Borrower and its
Subsidiaries with, and to be advised as to the same by, their officers, all at
such times and intervals as may be reasonably requested.

         SECTION 7.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES AND PERMITS;
MAINTENANCE OF MATERIAL LICENSES AND PERMITS. The Borrower will, and will cause
each Subsidiary to, (i) comply with the provisions of its charter documents and
by-laws; (ii) comply in all material respects with all agreements and
instruments by which it or any of its properties may be bound; (iii) comply with
all applicable laws and regulations (including Environmental Laws), decrees,
orders, judgments, licenses and permits, including, without limitation, all
environmental permits ("Applicable Requirements"), except where noncompliance
with such Applicable Requirements would not reasonably be expected to have a
material adverse effect in the aggregate on the consolidated financial
condition, properties or businesses of the Borrower and its Subsidiaries; (iv)
maintain all material operating permits for all landfills now owned or hereafter
acquired; and (v) dispose of hazardous waste only at licensed disposal
facilities operating, to the best of the Borrower's or such Subsidiary's
knowledge after reasonable inquiry, in compliance with Environmental Laws. If at
any time 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 Borrower or any Subsidiary may fulfill any of its
obligations hereunder or under any other Loan Document, the Borrower will
immediately take or cause to be taken all reasonable steps within the power of
the Borrower or such Subsidiary to obtain such authorization, consent, approval,
permit or license and furnish the Banks with evidence thereof.

         SECTION 7.11. ENVIRONMENTAL INDEMNIFICATION. The Borrower covenants and
agrees that it will indemnify and hold the Banks, the Issuing Banks and the
Administrative Agent and their respective affiliates, and each of the
representatives, agents and officers of each of the foregoing, harmless from and
against any and all claims, expense, damage, loss or liability incurred by the
Banks, the Issuing Banks or the Administrative Agent (including all costs of
legal representation incurred by the Banks, the Issuing Banks or the
Administrative Agent) relating to (a) any Release or threatened Release of
Hazardous Substances on the Real Property; (b) any violation of any
Environmental Laws or Applicable Requirements with respect to conditions at the
Real Property or other assets of the Borrower or its Subsidiaries, or the
operations conducted thereon;




<PAGE>   54
                                       48


or (c) the investigation or remediation of offsite locations at which the
Borrower, any of its Subsidiaries, or their predecessors are alleged to have
directly or indirectly Disposed of Hazardous Substances. It is expressly
acknowledged by the Borrower that this covenant of indemnification shall survive
the payment of the Loans and Reimbursement Obligations and satisfaction of all
other Obligations hereunder and shall inure to the benefit of the Banks, the
Issuing Banks, the Administrative Agent and their affiliates, successors and
assigns.

         SECTION 7.12. FURTHER ASSURANCES. The Borrower and the Guarantors will
cooperate with the Administrative Agent and execute such further instruments and
documents as the Administrative Agent shall reasonably request to carry out to
the Banks' satisfaction the transactions contemplated by this Agreement.

         SECTION 7.13. NOTICE OF POTENTIAL CLAIMS OR LITIGATION. The Borrower
shall 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 against the Borrower or any of its Subsidiaries wherein
the potential liability is in excess of $25,000,000 or which questions the
validity or enforceability of any Loan Document, together with a copy of each
such complaint or other notice received by the Borrower or any of its
Subsidiaries if requested by the Administrative Agent.

         SECTION 7.14. NOTICE OF CERTAIN EVENTS CONCERNING INSURANCE AND
ENVIRONMENTAL CLAIMS.

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

                  (b) The Borrower will promptly, and in any event within ten
         (10) Business Days of the Borrower's obtaining knowledge thereof,
         notify the Banks in writing of any of the following events:

                           (i) upon the Borrower's or any Subsidiary's obtaining
                  knowledge of any violation of any Environmental Law regarding
                  the Real Property or the Borrower's or any Subsidiary's
                  operations which violation could have a material adverse
                  effect on the business, financial condition, or assets of the
                  Borrower and its Subsidiaries on a consolidated basis;

                           (ii) upon the Borrower's or any Subsidiary's

                  threat of Release, of any Hazardous Substance at, from, or
                  into the Real Property which could materially affect the
                  business, financial condition, or assets of the Borrower and
                  its Subsidiaries on a consolidated basis;

                           (iii) upon the Borrower's or any Subsidiary's receipt
                  of any notice of any material violation of any Environmental

                                       49

                  federal, state, provincial, territorial or local governmental
                  officials) and including notice of any formal inquiry,
                  proceeding, demand, investigation or other action with regard
                  to (A) the Borrower's, any Subsidiary's or any Person's
                  operation of the Real Property, (B) contamination on, from, or

                  its predecessors are alleged to have directly or indirectly
                  Disposed of Hazardous Substances, and with respect to which
                  the liability associated therewith could be reasonably
                  expected to exceed $25,000,000; or

                           (iv) upon the Borrower's or any Subsidiary's
                  obtaining knowledge that any expense or loss which
                  individually or in the aggregate exceeds $25,000,000 has been
                  incurred by such governmental authority in connection with the
                  assessment, containment, removal or remediation of any
                  Hazardous Substances with respect to which the Borrower or any
                  Subsidiary may be liable or for which a lien may be imposed on
                  the Real Property.

         SECTION 7.15. NOTICE OF DEFAULT. The Borrower will promptly notify the
Banks in writing of the occurrence of any Default or Event of Default. If any
Person shall give any notice or take any other action in respect of a claimed
default (whether or not constituting an Event of Default) under this Agreement
or any other note, evidence of indebtedness, indenture or other obligation

the claimed default.

         SECTION 7.16. USE OF PROCEEDS. The proceeds of the Loans shall be used
for general corporate purposes. No proceeds of the Loans shall be used in any
way that will violate Regulations U or X of the Board of Governors of the
Federal Reserve System. No portion of the proceeds of any Loan 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

knowingly purchasing, or providing credit support for the purchase of, during

                  (e) Indebtedness of WMH listed in Schedule 8.1(e) on the terms
         and conditions existing on July 16, 1998, provided that any extension,

its general creditors; or acquire, or agree or have an option to acquire, any
property or assets upon conditional sale or other title retention or purchase
money security agreement, device or arrangement; or suffer to exist for a period

claim or demand against it which if unpaid might by law or upon bankruptcy or
insolvency, or otherwise, be given any priority whatsoever over its general
creditors; or sell, assign, pledge or otherwise transfer any accounts, contract
rights, general intangibles or chattel paper, with or without recourse, except
as follows (the "Permitted Liens"):

                  (a) Liens listed on Schedule 8.2(a) hereto;

                  (b) Liens securing Indebtedness permitted by Section 8.1(b)(i)
         hereof; provided that the assets subject to such liens and security
         interests shall be limited to those contracts to which such guaranty,
         suretyship or indemnification obligations relate and the rights to
         payment thereunder;

                  (c) Liens securing Indebtedness permitted under Section

         related contract rights, general intangibles, and chattel paper) so
         transferred and securing only the obligations with respect thereto);

                  (d) Liens to secure taxes, assessments and other government
         charges in respect of obligations not overdue;

                  (f) Liens in respect of judgments or awards which have been in
         force for less than the applicable period for taking an appeal so long
         as execution is not levied


<PAGE>   58
                                       52

         thereunder or in respect of which the Borrower (or any Subsidiary)
         shall at the time in good faith be prosecuting an appeal or proceedings
         for review and in respect of which a stay of execution shall have been
         obtained pending such appeal or review and in respect of which the
         Borrower maintains adequate reserves;

                  (g) Liens of carriers, warehousemen, mechanics and
         materialmen, and other like liens, in existence less than 120 days from
         the date of creation thereof in respect of obligations not overdue,
         provided that such liens may continue to exist for a period of more
         than 120 days if the validity or amount thereof shall currently be
         contested by the Borrower (or any Subsidiary) in good faith by
         appropriate proceedings and if the Borrower shall have set aside on its
         books adequate reserves with respect thereto as required by GAAP and
         provided further that the Borrower (or any Subsidiary) will pay any
         such claim forthwith upon commencement of proceedings to foreclose any
         such lien; and

                  (h) Encumbrances consisting of easements, rights of way,

         liens under leases to which the Borrower or any Subsidiary is a party,
         and other minor liens or encumbrances none of which in the opinion of
         the Borrower interferes materially with the use of the property
         affected in the ordinary conduct of the business of the Borrower or any
         of its Subsidiaries, which defects do not individually or in the
         aggregate have a material adverse effect on the business of the
         Borrower or any Subsidiary individually or of the Borrower and its
         Subsidiaries on a consolidated basis.

                  The Borrower and the Guarantors covenant and agree that if any
         of them or any of their Subsidiaries shall create or assume any lien
         upon any of their respective properties or assets, whether now owned or
         hereafter acquired, other than Permitted Liens (unless prior written
         consent shall have been obtained from the Banks), the Borrower and the
         Guarantors will make or cause to be made effective provision whereby
         the Obligations and their respective Guaranteed Obligations will be
         secured by such lien equally and ratably with any and all other
         Indebtedness thereby secured so long as such other Indebtedness shall
         be so secured; provided, that the covenants of the Borrower and the
         Guarantors contained in this sentence shall only be in effect for so
         long as the Borrower or any Guarantor shall be similarly obligated
         under any other Indebtedness; provided, further, that an Event of
         Default shall occur for so long as such other Indebtedness becomes
         secured notwithstanding any actions taken by the Borrower or any
         Guarantor to ratably secure the Obligations and the Guaranteed
         Obligations hereunder.

         SECTION 8.3. RESTRICTIONS ON INVESTMENTS. Except to the extent provided
in Section 8.4, neither the Borrower nor any Subsidiary may make or permit to
exist or to remain outstanding any Investment, unless both before and after
giving effect thereto (i) the Borrower and its Subsidiaries are in compliance
with the covenants set forth in Section Section 7, 8 and 9 hereof; (ii) there
does not exist a Default or Event of Default and no Default or Event of Default

having capital and surplus of not less than $100,000,000, and (C) wholly owned
Subsidiaries, does not exceed 10% of Consolidated Tangible Assets; provided,

governed by Section 8.1.

         SECTION 8.4. MERGERS, CONSOLIDATIONS, SALES.

                  (a) Neither the Borrower nor any Subsidiary shall be a party
         to any merger, consolidation or exchange of stock unless the Borrower
         shall be the surviving entity with respect to any such transaction to
         which the Borrower is a party and a Guarantor shall be the survivor of
         any merger with any Subsidiary which is not Guarantor or a Subsidiary
         shall be the surviving entity (and continue to be a Subsidiary) with
         respect to any such transactions to which one or more Subsidiaries is a
         party (and the conditions set forth below are satisfied), or purchase
         or otherwise acquire all or substantially all of the assets or stock of
         any class of, or any partnership, membership or joint venture or other
         interest in, any other Person except as otherwise provided in Section

         and its Subsidiaries may purchase or otherwise acquire all or
         substantially all of the assets or stock of any class of, or joint
         venture or other interest in, any Person if the following conditions
         have been met: (i) the proposed transaction will not otherwise create a
         Default or an Event of Default hereunder; (ii) the business to be
         acquired predominantly involves (A) the collection, transfer, hauling,

         consent of the Majority Banks; (iii) the business to be acquired

         Subsidiaries to incur any Indebtedness in connection with any
         transaction permitted pursuant to this Section 8.4 shall be governed by
         Section 8.1.

                  (b) Neither the Borrower nor any Subsidiary shall sell,
         transfer, convey or lease any assets or group of assets including the
         sale or transfer of any property owned by the Borrower or any

         same purpose as the property being sold or transferred (except (1)

         Borrower which are wholly owned by the Borrower, (2) Regulatory
         Dispositions, (3) Strategic Dispositions, (4) Allied Waste Transactions

         (60) days past due sold or assigned in the ordinary course of
         collecting past due accounts, or pursuant to a Permitted Receivables
         Transaction).

                  (c) Commencing with the Effective Date, at any time when the
         aggregate Net Cash Proceeds from all Domestic Strategic Dispositions
         not previously applied or set aside for application under this Section
         8.4(c) exceeds $25,000,000 in the aggregate, then all such Net Cash
         Proceeds (including the first $25,000,000) received by the Borrower or
         any Subsidiary from Domestic Strategic Dispositions shall be applied
         within five (5) Business Days to pay down the Existing Domestic Bank

         shall be used first to permanently pay down the European Credit
         Facilities (and concurrent permanent reduction of the commitments of
         the lenders to advance funds or provide credit thereunder by the amount
         of such pay down), with any surplus to be treated as if such surplus
         were Net Cash Proceeds from a Domestic Strategic Disposition in

         provide a monthly report to the Administrative Agent in the form of
         Exhibit L hereto of Net Cash Proceeds from all European Strategic

capital stock (other than in connection with a merger permitted by Section 8.4
hereof or conversion into another form of equity of any preferred shares of the

provided that, so long as no Default or Event of Default exists or would be
created hereunder, the Borrower and its Subsidiaries may (i) pay cash dividends
and redeem stock in an aggregate amount not to exceed Net Cash Proceeds from
Strategic Dispositions available for share repurchase in accordance with the
table set forth above in Section 8.4(c), provided further that, giving effect to

Subsidiary to the Borrower.

         SECTION 8.6. EMPLOYEE BENEFIT PLANS. None of the Borrower, any of its
Subsidiaries, or any ERISA Affiliate will:

                  (a) engage in any "prohibited transaction" within the meaning
         of Section 406 of ERISA or Section 4975 of the Code which could result
         in a material liability for the Borrower on a consolidated basis; or

                  (b) permit any Guaranteed Pension Plan to incur an
         "accumulated funding deficiency", as such term is defined in Section
         302 of ERISA, whether or not such deficiency is or may be waived; or

                  (c) fail to contribute to any Guaranteed Pension Plan to an
         extent which, or terminate any Guaranteed Pension Plan in a manner
         which, could result in the imposition of a lien or encumbrance on the
         assets of the Borrower or any Guarantor pursuant to Section 302(f) or
         Section 4068 of ERISA; or

                  (d) permit or take any action which would result in the
         aggregate benefit liabilities (within the meaning of Section 4001 of
         ERISA), other than with respect to the


<PAGE>   62

                                       56


         Terminated Plans, of all Guaranteed Pension Plans exceeding the value
         of the aggregate assets of such Plans, disregarding for this purpose
         the benefit liabilities and assets of any such Plan with assets in
         excess of benefit liabilities; or

                  (e) take any action referred to in paragraph (a), (b), (c) or
         (d) above that would violate any provisions of Applicable Canadian
         Pension Legislation.

         The Borrower and its Subsidiaries will (i) promptly upon the request of
any Bank or the Administrative Agent, furnish to the Banks a copy of the most
recent actuarial statement required to be submitted under Section 103(d) of
ERISA and Annual Report, Form 5500, with all required attachments, in respect of
each Guaranteed Pension Plan and (ii) promptly upon receipt or dispatch, furnish

assets or financial condition of the Borrower and its Subsidiaries as a whole,

Letter of Credit issuance, extension or renewal.

         SECTION 11.3. NO LEGAL IMPEDIMENT. No change shall have occurred in any

Issuing Bank to issue, extend or renew, or the Banks to participate in, Letters
of Credit hereunder.

         SECTION 11.4. GOVERNMENTAL REGULATION. The Banks shall have received

         or agreement contained herein or in any of the other Loan Documents
         (other than those specified in subsections (a), (b), and (c) above) and

         of such failure shall have been given to the Borrower by the
         Administrative Agent or any of the Banks;

                  (e) if any representation or warranty contained in this

         material respect upon the date when made or repeated;

         to observe or perform any material term, covenant or agreement
         contained in any one or more agreements by which it is bound,
         evidencing or securing any Indebtedness in an aggregate amount greater
         than $50,000,000 for such period of time as would permit, 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 or terminate its commitment with
         respect thereto;

                  (g) if the Borrower, any Guarantor or any Material Subsidiary
         makes an assignment for the benefit of creditors, or admits in writing
         its inability to pay or generally fails to pay its debts as they mature
         or become due, or petitions or applies for the appointment of a trustee
         or other custodian, liquidator or receiver of the Borrower, the
         Guarantors or any Material Subsidiary, or of any substantial part of
         the assets of the Borrower, the Guarantors or any Material Subsidiary
         or commences any case or other proceeding relating to the Borrower, the
         Guarantors or any Material Subsidiary under any bankruptcy,
         reorganization, arrangement, insolvency, readjustment of debt,
         dissolution or liquidation or similar law of any jurisdiction, now or
         hereafter in effect, or takes any action to authorize or in furtherance
         of any of the foregoing, or if any such petition or application is
         filed or any such case or other proceeding is commenced against the
         Borrower, the Guarantors or any Material Subsidiary or the Borrower,
         any Guarantor or any Material Subsidiary indicates its approval
         thereof, consent thereto or acquiescence therein;

                  (h) if a decree or order is entered appointing any such
         trustee, custodian, liquidator or receiver or adjudicating the Borrower

         Guarantor or any Material Subsidiary in an involuntary case under
         federal bankruptcy laws of any jurisdiction as now or hereafter
         constituted, and such decree or order remains in effect for more than
         30 days, whether or not consecutive;


<PAGE>   67

                                       61



                  (i) if there shall remain in force, undischarged, unsatisfied
         and unstayed, for more than thirty days, whether or not consecutive,
         any final judgment against the Borrower or any Subsidiary which, with
         other outstanding final judgments against the Borrower and its
         Subsidiaries exceeds in the aggregate $25,000,000 after taking into
         account any undisputed insurance coverage;

                  (j) if, with respect to any Guaranteed Pension Plan (or any
         corresponding plan described in any Applicable Canadian Pension
         Legislation), an ERISA Reportable Event or similar event under
         Applicable Canadian Pension Legislation shall have occurred and the
         Banks shall have determined in their reasonable discretion that such
         event reasonably could be expected to result in liability of the
         Borrower or any Subsidiary to the PBGC or similar Canadian authorities
         or the Plan in an aggregate amount exceeding $25,000,000 and such event
         in the circumstances occurring reasonably could constitute grounds for
         the partial or complete termination of such Plan by the PBGC or similar
         Canadian authorities or for the appointment by the appropriate United
         States District Court or Canadian Court of a trustee to administer such
         Plan; or a trustee shall have been appointed by the appropriate United
         States District Court or Canadian Court to administer such Plan; or the

                  (k) if any of the Loan Documents shall be cancelled,
         terminated, revoked or rescinded otherwise than in accordance with the
         terms thereof or with the express prior written agreement, consent or
         approval of the Banks, or any action at law, suit or in equity or other
         legal proceeding to cancel, revoke or rescind any of the Loan Documents
         shall be commenced by or on behalf of the Borrower, any Guarantor, or
         any of their respective stockholders, or any court or any other
         governmental or regulatory authority or agency of competent
         jurisdiction 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; or

                  (l) if any person or group of persons (within the meaning of
         Section 13 or 14 of the Securities Exchange Act of 1934, as amended)
         shall have acquired beneficial ownership (within the meaning of Rule
         13d-3 promulgated by the Securities and Exchange Commission under said
         Act) of 25% or more of the outstanding shares of common voting stock of
         the Borrower; or during any period of twelve consecutive calendar
         months, individuals who were directors of the Borrower on the first day
         of such period shall cease to constitute a majority of the board of
         directors of the Borrower;

then, and in any such event, so long as the same may be continuing, the
Administrative Agent may, and upon the request of the Majority Banks shall, by
notice in writing to the Borrower, declare all amounts owing with respect to
this 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, notice of intent to
accelerate, notice of acceleration to the extent permitted by law or other
notice of any kind, all of which are hereby expressly waived by the Borrower;
provided that in the event of any Event of Default specified in Section 12.1(g)
or 12.1(h), all such amounts shall become immediately due and



<PAGE>   68
                                       62



payable automatically and without any requirement of notice from the
Administrative Agent or any Bank. Upon demand by the Majority Banks after the
occurrence of any Event of Default, the Borrower shall immediately provide to
the Administrative Agent cash in an amount equal to the aggregate Maximum
Drawing Amount to be held by the Administrative Agent as collateral security for
the Reimbursement Obligations.

         SECTION 12.2. TERMINATION OF COMMITMENTS. If any Event of Default
pursuant to Sections 12.1(g) or 12.1(h) hereof shall occur, any unused portion
of the Total Commitment hereunder shall forthwith terminate and the Banks and
the Issuing Banks shall be relieved of all obligations to make Loans or to
issue, extend or renew Letters of Credit hereunder; or if any other Event of
Default shall occur, the Majority Banks may by notice to the Borrower 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 and the Issuing Banks shall be relieved of
all further obligations to make Loans or to issue, extend or renew Letters of
Credit hereunder. No termination of any portion of the Total Commitment
hereunder shall relieve the Borrower of any of its existing Obligations to the
Banks, the Issuing Banks or the Administrative Agent hereunder or elsewhere.

         SECTION 12.3. REMEDIES. In case any one or more of the Events of
Default shall have occurred and be continuing, and whether or not the Banks
shall have accelerated the maturity of the Loans and other Obligations pursuant
to Section 12.1, each Bank, upon notice to the other Banks, if owed any amount
with respect to the Loans or the Reimbursement Obligations, may 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 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, any recovery being subject to the terms
of Section 29 hereof. No remedy herein conferred upon any Bank or the
Administrative Agent or the holder of any Note 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 Borrower and any securities or other
property of the Borrower in the possession of such Bank may be applied to or set
off against the payment of 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 Borrower to the Banks or the Administrative Agent.
Any amounts set off pursuant to this Section 13 shall be distributed ratably in
accordance with Section 29 among all of the Banks by the Bank setting off such
amounts. If any Bank fails to share such setoff ratably, the Administrative
Agent shall have the right to withhold such Bank's share of the Borrower's
payments until each of the Banks shall have, in the aggregate, received a pro
rata repayment.


<PAGE>   69
                                       63



         SECTION 14. EXPENSES. Whether or not the transactions contemplated
herein shall be consummated, the Borrower hereby promises to reimburse the
Administrative Agent for all reasonable out-of-pocket fees and disbursements
(including all reasonable attorneys' fees) incurred or expended in connection
with the preparation, filing or recording, or interpretation of this Agreement,
the other Loan Documents, or any amendment, modification, approval, consent or
waiver hereof or thereof. The Borrower further promises to reimburse the
Administrative Agent and the Banks for all reasonable out-of-pocket fees and
disbursements (including all reasonable legal fees and the allocable cost of
in-house attorneys' fees) incurred or expended in connection with the
enforcement of any Obligations or the satisfaction of any indebtedness of the
Borrower hereunder or under any other Loan Document, or in connection with any
litigation, proceeding or dispute hereunder in any way related to the credit
hereunder. The Borrower also promises to pay the Administrative Agent all
reasonable out-of-pocket fees and disbursements, incurred or expended in
connection with the Competitive Bid Loan procedure under Section 4 hereof.

         SECTION 15. THE ADMINISTRATIVE AGENT.

         SECTION 15.1. APPOINTMENT, POWERS AND IMMUNITIES. Each Bank hereby
irrevocably appoints and authorizes MGT to act as Administrative Agent,
provided, however, the Administrative Agent is hereby authorized to serve only
as administrative and documentation agent for the Banks and to exercise such
powers as are reasonably incidental thereto and as are set forth in this
Agreement and the other Loan Documents. The Administrative 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
Agreement or the Loan Documents. Except as provided in this Agreement, and in
the other Loan Documents, the Administrative Agent shall take action or refrain
from acting only upon instructions of the Banks. It is agreed that the duties,
rights, privileges and immunities of the Issuing Banks, in their capacity as
issuers of Letters of Credit hereunder, shall be identical to the duties,
rights, privileges and immunities of the Administrative Agent as provided in
this Section 15. The Administrative Agent shall not have any duties or
responsibilities or any fiduciary relationship with any Bank except those
expressly set forth in this Agreement and the other Loan Documents. Neither the
Administrative Agent nor any of its affiliates shall be responsible to the Banks
for any recitals, statements, representations or warranties made by the Borrower
or any other Person whether contained herein or otherwise or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement, the other Loan Documents or any other document referred to or
provided for herein or therein or for any failure by the Borrower or any other
Person to perform its obligations hereunder or thereunder or in respect of the
Notes. The Administrative 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 Administrative Agent,
the Agents and any of their directors, officers, employees or agents shall not
be responsible for any action taken or omitted to be taken by it or them
hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct. The Administrative Agent in its separate
capacity as a Bank shall have the same rights and powers hereunder as any other
Bank.

         SECTION 15.2. ACTIONS BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be fully justified in failing or refusing to take any action under this
Agreement as reasonably deemed



<PAGE>   70
                                       64



appropriate unless it shall first have received the consent of the Majority
Banks (or, when expressly required hereby, all 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 Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement
or any of the Loan Documents in accordance with the instruction of the Majority
Banks (or, when expressly required hereby or thereby, all of the Banks), and
such instruction 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 15.3. INDEMNIFICATION. Without limiting the obligations of the
Borrower hereunder or under any other Loan Document, the Banks agree to
indemnify the Administrative Agent, its affiliates and its respective directors,
officers, agents and employees (to the extent not reimbursed by the Borrower)
ratably in accordance with their respective Commitment Percentages for any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may at any time be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of this Agreement or
any other Loan Document or any documents contemplated by or referred to herein
or therein or the transactions contemplated hereby or thereby or the enforcement
of any of the terms hereof or thereof or of any such other documents; provided,
that no Bank shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the Administrative Agent (or
any agent thereof) and provided further that no Bank shall be liable with
respect to acts of Section 20 Subsidiaries of other Banks, IT BEING THE INTENT
OF THE PARTIES HERETO THAT ALL SUCH INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR
THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

         SECTION 15.4. REIMBURSEMENT. Without limiting the provisions of
Sections 5.1(a), 5.13, and 13, the Administrative Agent shall not be obliged to
make available to any Person any sum which the Administrative Agent is expecting
to receive for the account of that Person until the Administrative Agent has
determined that it has received that sum. The Administrative Agent may, however,
disburse funds prior to determining that the sums which the Administrative Agent
expects to receive have been finally and unconditionally paid to the
Administrative Agent, if the Administrative Agent wishes to do so. If and to the
extent that the Administrative Agent does disburse funds and it later becomes
apparent that the Administrative Agent did not then receive a payment in an
amount equal to the sum paid out, then any Person to whom the Administrative
Agent made the funds available shall, on demand from the Administrative Agent,
refund to the Administrative Agent the sum paid to that Person. If, in the
opinion of the Administrative Agent, the distribution of any amount received by
it in such capacity hereunder or under the other 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 Administrative Agent is to be repaid, each Person to whom any
such distribution shall have been made shall either repay to the Administrative
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.

                                       65



         SECTION 15.5. DOCUMENTS. The Administrative Agent will forward to each
Bank, promptly after receipt thereof, a copy of each notice or other document
furnished to the Administrative Agent for such Bank hereunder; provided,
however, that, notwithstanding the foregoing, the Administrative 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 15.6. NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER BANKS.
Each Bank represents that it has, independently and without reliance on the
Administrative Agent, the Agents 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 Borrower and the Guarantors and the
decision to enter into this Agreement and the other Loan Documents and agrees
that it will, independently and without reliance upon the Administrative Agent,
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 Agreement or any other Loan
Document. Except as herein expressly provided to the contrary, the
Administrative Agent shall not be required to keep informed as to the
performance or observance by the Borrower and the Guarantors of this 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 Administrative Agent hereunder, the Administrative
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 Administrative Agent or any of their affiliates. Each Bank
shall have access to all documents relating to the Administrative Agent's
performance of their duties hereunder at such Bank's request. Unless any Bank
shall promptly object to any action taken by the Administrative Agent hereunder
of which such Bank has actual knowledge (other than actions which require the
prior consent of such Bank in accordance with the terms hereof or to which the
provisions of Section 15.8 are applicable and other than actions which
constitute gross negligence or willful misconduct by the Administrative Agent),
such Bank shall be presumed to have approved the same.

         SECTION 15.7. RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative
Agent may resign at any time by giving 60 days' prior written notice thereof to
the Banks and the Borrower. Upon any such resignation, the Banks (other than the
resigning Administrative Agent) shall have the right to appoint a successor
Administrative Agent from among the Banks. If no successor to the Administrative
Agent shall have been so appointed by the Banks and shall have accepted such
appointment within 30 days after the retiring Administrative Agent's giving of
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent from among the remaining
Banks, which shall be a financial institution having a combined capital and
surplus in excess of $1,000,000,000. Upon the acceptance of any appointment as
the Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After the retiring Administrative Agent's
resignation, the provisions of this Agreement shall continue in effect for its
benefit in respect of any actions taken or omitted to be



<PAGE>   72
                                       66



taken by it while it was acting as the Administrative Agent. Any new Issuing
Bank appointed pursuant to this Section 15.7 shall immediately issue new Letters
of Credit in place of Letters of Credit previously issued or, if acceptable to
the resigning Issuing Bank, issue letters of credit in favor of the resigning
Issuing Bank as security for the outstanding Letters of Credit and shall in due
course replace all Letters of Credit previously issued by the resigning Issuing
Bank.

         SECTION 15.8. ACTION BY THE BANKS, CONSENTS, AMENDMENTS, WAIVERS, ETC.
Any action to be taken (including the giving of notice) may be taken, any
consent or approval required or permitted by this Agreement or any other Loan
Document to be given by the Banks may be given, any term of this Agreement, any
other Loan Document or any other instrument, document or agreement related to
this Agreement or the other Loan Documents or mentioned therein may be amended,
and the performance or observance by the Borrower or any other Person of any of
the terms thereof and any Default or Event of Default (as defined in any of the
above-referenced documents or instruments) may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Majority Banks; provided, however, that no such consent
or amendment which affects the rights, duties or liabilities of the
Administrative Agent or any Issuing Bank shall be effective without the written
consent of the Administrative Agent or such Issuing Bank, as the case may be.
Notwithstanding the foregoing, no amendment, waiver or consent shall do any of
the following unless in writing and signed by ALL of the Banks (a) increase the
principal amount of the Total Commitment (or subject any Bank to any additional
obligations), (b) reduce the principal of or interest on the Notes (including,
without limitation, interest on overdue amounts) or any fees payable hereunder,
(c) postpone any date fixed for any payment in respect of principal or interest
(including, without limitation, interest on overdue amounts) on the Notes or any
fee hereunder; (d) change the definition of "Majority Banks" or 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 15.8; (f) change the Commitment
Percentage of any Bank, except as permitted under Section 20 hereof, (g) change
the Total Commitment Percentage of any Bank, or (h) release the Borrower or any
Guarantor from its obligations hereunder (except as expressly set forth herein).

         SECTION 16. INDEMNIFICATION. The Borrower agrees to indemnify and hold
harmless the Banks, the Agents, the Issuing Banks, and the Administrative Agent
and their affiliates, as well as the Banks' and the Administrative Agent's and
their affiliates' shareholders, directors, agents, officers, subsidiaries and
affiliates, from and against all damages, losses, settlement payments,
obligations, liabilities, claims, suits, penalties, assessments, citations,
directives, demands, judgments, actions or causes of action, whether statutorily
created or under the common law, and reasonable costs and expenses incurred,
suffered, sustained or required to be paid by an indemnified party by reason of
or resulting from the transactions contemplated hereby, except any of the
foregoing which result from the gross negligence or willful misconduct of any
indemnified party. In any investigation, enforcement matter, proceeding or
litigation, or the preparation therefor, the Banks and the Administrative Agent
shall be entitled to select their own counsel and, in addition to the foregoing
indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses
of such counsel. In the event of the commencement of any such proceeding or
litigation against the Banks or Administrative Agent by third parties, the
Borrower shall be entitled to participate in such proceeding or litigation with
counsel of their choice at their expense, provided that such counsel shall be
reasonably satisfactory to the Banks or



<PAGE>   73
                                       67



Administrative Agent. The covenants of this Section 16 shall survive payment or
satisfaction of payment of amounts owing with respect to any Note or any other
Loan Document and satisfaction of all the Obligations hereunder, IT BEING THE
INTENT OF THE PARTIES HERETO THAT ALL SUCH INDEMNIFIED PARTIES SHALL BE
INDEMNIFIED FOR THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

<PAGE>   74
                                       68



         SECTION 17. WITHHOLDING TAXES. The Borrower hereby agrees that:

                  (a) Any and all payments made by the Borrower hereunder shall
         be made free and clear of, and without deduction for, any and all
         present or future taxes, levies, fees, duties, imposts, deductions,
         charges or withholdings of any nature whatsoever, excluding, in the
         case of the Administrative Agent or the Banks or any holder of the
         Notes, (i) taxes imposed on, or measured by, its net income or profits,
         (ii) franchise taxes imposed on it, (iii) taxes imposed by any
         jurisdiction as a direct consequence of it, or any of its affiliates,
         having a present or former connection with such jurisdiction,
         including, without limitation, being organized, existing or qualified
         to do business, doing business or maintaining a permanent establishment
         or office in such jurisdiction, and (iv) taxes imposed by reason of its
         failure to comply with any applicable certification, identification,
         information, documentation or other reporting requirement (all such
         non-excluded taxes being hereinafter referred to as "Indemnifiable
         Taxes"). In the event that any withholding or deduction from any
         payment to be made by the Borrower hereunder is required in respect of
         any Indemnifiable Taxes pursuant to any applicable law, or governmental
         rule or regulation, then the Borrower will (i) direct to the relevant
         taxing authority the full amount required to be so withheld or
         deducted, (ii) forward to the Administrative Agent for delivery to the
         applicable Bank an official receipt or other documentation satisfactory
         to the Administrative Agent and the applicable Bank evidencing such
         payment to such taxing authority, and (iii) direct to the
         Administrative Agent for the account of the relevant Banks such
         additional amount or amounts as is necessary to ensure that the net
         amount actually received by each relevant Bank will equal the full
         amount such Bank would have received had no such withholding or
         deduction (including any Indemnifiable Taxes on such additional
         amounts) been required. Moreover, if any Indemnifiable Taxes are
         directly asserted against the Administrative Agent or any Bank with
         respect to any payment received by the Administrative Agent or such
         Bank by reason of the Borrower's failure to properly deduct and
         withhold such Indemnifiable Taxes from such payment, the Administrative
         Agent or such Bank may pay such Indemnifiable Taxes and the Borrower
         will promptly pay all such additional amounts (including any penalties,
         interest or reasonable expenses) as is necessary in order that the net
         amount received by such Person after the payment of such Indemnifiable
         Taxes (including any Indemnifiable Taxes on such additional amount)
         shall equal the amount such Person would have received had not such
         Indemnifiable Taxes been asserted. Any such payment shall be made
         promptly after the receipt by the Borrower from the Administrative
         Agent or such Bank, as the case may be, of a written statement setting
         forth in reasonable detail the amount of the Indemnifiable Taxes and
         the basis of the claim.

                  (b) The Borrower shall pay any present or future stamp or
         documentary taxes or any other excise or any other similar levies which
         arise from any payment made hereunder or from the execution, delivery
         or registration of, or otherwise with respect to, this Agreement or any
         other Loan Document ("Other Taxes").

                  (c) The Borrower hereby indemnifies and holds harmless the
         Administrative Agent and each Bank for the full amount of Indemnifiable
         Taxes or Other Taxes



<PAGE>   75
                                       69



         (including, without limitation, any Indemnifiable Taxes or Other Taxes
         imposed on amounts payable under this Section 17) paid by the
         Administrative Agent or such Bank, as the case may be, and any
         liability (including penalties, interest and reasonable expenses)
         arising therefrom or with respect thereto, by reason of the Borrower's
         failure to properly deduct and withhold Indemnifiable Taxes pursuant to
         paragraph (a) above or to properly pay Other Taxes pursuant to
         paragraph (b) above. Any indemnification payment from the Borrower
         under the preceding sentence shall be made promptly after receipt by
         the Borrower from the Administrative Agent or Bank of a written
         statement setting forth in reasonable detail the amount of such
         Indemnifiable Taxes or such Other Taxes, as the case may be, and the
         basis of the claim.

                  (d) If the Borrower pays any amount under this Section 17 to
         the Administrative Agent or any Bank and such payee knowingly receives
         a refund of any taxes with respect to which such amount was paid, the
         Administrative Agent or such Bank, as the case may be, shall pay to the
         Borrower the amount of such refund promptly following the receipt
         thereof by such payee.

                  (e) In the event any taxing authority notifies the Borrower or
         any Guarantor that any of them has improperly failed to deduct or
         withhold any taxes (other than Indemnifiable Taxes) from a payment made
         hereunder to the Administrative Agent or any Bank, the Borrower shall
         timely and fully pay such taxes to such taxing authority.

                  (f) The Administrative Agent or the Banks shall, upon the
         request of the Borrower, take reasonable measures to avoid or mitigate
         the amount of Indemnifiable Taxes required to be deducted or withheld
         from any payment made hereunder if such measures can be taken without
         such Person in its sole judgment suffering any legal, regulatory or
         economic disadvantage.

                  (g) Without prejudice to the survival of any other agreement
         of the parties hereunder, the agreements and obligations of the
         Borrower contained in this Section 17 shall survive the payment in full
         of the Obligations.

         SECTION 18.  TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.

         SECTION 18.1. SHARING OF INFORMATION WITH SECTION 20 SUBSIDIARY. The
Borrower acknowledges that from time to time financial advisory, investment
banking and other services may be offered or provided to the Borrower or one or
more of its Subsidiaries, in connection with this Agreement or otherwise, by a
Section 20 Subsidiary. The Borrower, for itself and each of its Subsidiaries,
hereby authorizes (a) such Section 20 Subsidiary to share with the
Administrative Agent and each Bank any information delivered to such Section 20
Subsidiary by the Borrower or any of its Subsidiaries, and (b) the
Administrative Agent and each Bank to share with such Section 20 Subsidiary any
information delivered to the Administrative Agent or such Bank by the Borrower
or any of its Subsidiaries pursuant to this Agreement, or in connection with the
decision of such Bank to enter into this Agreement; it being understood, in each
case, that any such Section 20 Subsidiary receiving such information shall be
bound by the confidentiality provisions of this Agreement. Such authorization
shall survive the payment and satisfaction in full of all of Obligations.


<PAGE>   76
                                       70



         SECTION 18.2. CONFIDENTIALITY. Each of the Banks and the Administrative
Agent agrees, on behalf of itself and each of its affiliates, directors,
officers, employees and representatives, to use reasonable precautions to keep
confidential, in accordance with their customary procedures for handling
confidential information of the same nature and in accordance with safe and
sound banking practices, any non-public information supplied to it by the
Borrower or any of its Subsidiaries pursuant to this Agreement that is
identified by such Person as being confidential at the time the same is
delivered to the Banks or the Administrative Agent, provided that nothing herein
shall limit the disclosure of any such information (a) after such information
shall have become public other than through a violation of this Section 18, (b)
to the extent required by statute, rule, regulation or judicial process, (c) to
counsel for any of the Banks or the Administrative Agent, (d) to bank examiners
or any other regulatory authority having jurisdiction over any Bank or the
Administrative Agent, or to auditors or accountants, (e) to the Administrative
Agent, any Bank or any Section 20 Subsidiary, (f) in connection with any
litigation to which any one or more of the Banks, the Administrative Agent or
any Section 20 Subsidiary is a party, or in connection with the enforcement of
rights or remedies hereunder or under any other Loan Document, (g) to a
Subsidiary or affiliate of such Bank as provided in Section 18.1 or (h) to any
assignee or participant (or prospective assignee or participant) so long as such
assignee or participant agrees to be bound by the provisions of Section 20.

         SECTION 18.3. PRIOR NOTIFICATION. Unless specifically prohibited by
applicable law or court order, each of the Banks and the Administrative Agent
shall, prior to disclosure thereof, notify the Borrower of any request for
disclosure of any such non-public information by any governmental agency or
representative thereof (other than any such request in connection with an
examination of the financial condition of such Bank by such governmental agency)
or pursuant to legal process.

         SECTION 18.4. OTHER. In no event shall any Bank or the Administrative
Agent be obligated or required to return any materials furnished to it or any
Section 20 Subsidiary by the Borrower or any of its Subsidiaries. The
obligations of each Bank under this Section 18 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 Borrower 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.

         SECTION 19. 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 Borrower or any Guarantor pursuant hereto shall be deemed to have
been relied upon by the Banks, the Issuing Banks and the Administrative Agent,
notwithstanding any investigation heretofore or hereafter made by them, and
shall survive the making by the Banks of the Loans and the issuance, extension
or renewal of any Letters of Credit by any Issuing Bank, as herein contemplated,
and shall continue in full force and effect so long as any amount due under this
Agreement, any Obligation, any Letter of Credit or any Note remains outstanding
and unpaid or any Bank has any obligation to make any Loans or any Issuing Bank
has any obligation to issue, extend, or renew any Letters of Credit hereunder.
All statements contained in any certificate or other paper



<PAGE>   77
                                       71



delivered by or on behalf of the Borrower pursuant hereto or in connection with
the transactions contemplated hereby shall constitute representations and
warranties by the Borrower hereunder.

         SECTION 20. ASSIGNMENT AND PARTICIPATION. It is understood and agreed
that each Bank shall have the right to assign at any time all or a portion of
its Commitment Percentage and interests in the risk relating to the Loans,
outstanding Letters of Credit and its Commitment hereunder in an amount equal to
or greater than $5,000,000 (or, if a Bank's Commitment is less than $5,000,000,
in a minimum amount equal to such Bank's Commitment, provided that prior to any
Commitment reductions pursuant to Section 2.3, such Bank's Commitment was at
least $10,000,000) to additional banks or other financial institutions with the
prior written approval of the Administrative Agent and, so long as no Event of
Default has occurred and is continuing, the Borrower, which approvals shall not
be unreasonably withheld. Any Bank may at any time, and from time to time,
assign to any branch, lending office, or affiliate or such Bank all or any part
of its rights and obligations under the Loan Documents by notice to the
Administrative Agent and the Borrower. It is further agreed that each bank or
other financial institution which executes and delivers to the Administrative
Agent and the Borrower hereunder an Assignment and Acceptance substantially in
the form of Exhibit G hereto (an "Assignment and Acceptance") together with an
assignment fee in the amount of $3,500 payable by the assigning Bank to the
Administrative Agent, shall, on the date specified in such Assignment and
Acceptance, become a party to this Agreement and the other Loan Documents for
all purposes of this Agreement and the other Loan Documents, and its portion of
the Commitment, the Loans and Letters of Credit shall be as set forth in such
Assignment and Acceptance. The Bank assignor thereunder shall, to the extent
that rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement and the other Loan Documents. Upon the
execution and delivery of such Assignment and Acceptance, (a) the Borrower shall
issue to the assignee bank or other financial institution Notes in the amount of
such bank's or other financial institution's Commitment dated the date of the
assignment or such other date as may be specified by the Administrative Agent,
and otherwise completed in substantially the form of Exhibits A or B, and to the
extent any assigning Bank has retained a portion of its obligations hereunder, a
replacement Syndicated Note, to the assigning Bank reflecting its assignment;
(b) to the extent applicable, the Borrower shall issue a Competitive Bid Note in
substantially the form of Exhibit C (and a replacement Competitive Bid Note) or
the Administrative Agent shall make appropriate entries on the Competitive Bid
Loan Accounts to reflect such assignment of Competitive Bid Loan(s); (c) the
Administrative Agent shall distribute to the Borrower, the Banks and such bank
or financial institution a revised Schedule 1 reflecting such changes; and (d)
this Agreement shall be deemed to be appropriately amended to reflect (i) the
status of the bank or financial institution as a party hereto and (ii) the
status and rights of the Banks hereunder.

         Each Bank shall also have the right to grant participations to one or
more banks or other financial institutions in its Commitment, the Loans and
outstanding Letters of Credit. The documents evidencing any such participation
shall limit such participating bank's or financial institution's voting rights
with respect to this Agreement to the matters set forth in Section 15.8 which
require the approval of all Banks.


<PAGE>   78
                                       72



         Notwithstanding the foregoing, no assignment or participation shall
operate to increase the Total Commitment hereunder or otherwise alter the
substantive terms of this Agreement, and no Bank which retains a Commitment
hereunder shall have a Commitment of less than $10,000,000, as such amount may
be reduced upon reductions in the Total Commitment pursuant to Section 2.3
hereof.

         Anything contained in this Section 20 to the contrary notwithstanding,
any Bank may at any time pledge all or any portion of its interest and rights
under this 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.

         The Borrower agrees that in addition to disclosures made in accordance
with standard and customary banking practices any Bank may disclose information
obtained by such Bank pursuant to this Agreement to assignees or participants
and potential assignees or participants hereunder; provided that such assignees
or participants or potential assignees or participants shall agree to be bound
by Section 18 hereof.

         SECTION 21. PARTIES IN INTEREST. All the terms of this Agreement and
the other Loan Documents shall be binding upon and inure to the benefit of and
be enforceable by the respective successors and assigns of the parties hereto
and thereto; provided, that the Borrower shall not assign or transfer its rights
or obligations hereunder or thereunder without the prior written consent of each
of the Banks.

         SECTION 22. NOTICES, ETC. Except as otherwise expressly provided in
this Agreement, all notices and other communications made or required to be
given pursuant to this Agreement or the other Loan Documents shall be in writing
and shall be delivered in hand, mailed by United States first class mail,

severable and if any one clause or provision hereof shall be held invalid or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in

         SECTION 28. GUARANTY.

         SECTION 28.1. GUARANTY. For value received and hereby acknowledged and
as an inducement to the Banks and the Issuing Banks to make the Loans available
to the Borrower, and issue, extend or renew Letters of Credit for the account of
the Borrower, each Guarantor hereby unconditionally and irrevocably guarantees
(a) the full punctual payment when due, whether at stated maturity, by
acceleration or otherwise, of all Obligations of the Borrower now or hereafter
existing whether for principal, interest, fees, expenses or otherwise, and (b)
the strict performance and observance by the Borrower of all agreements,
warranties and covenants applicable to the Borrower in the Loan Documents and
(c) the obligations of the Borrower under the Loan Documents (such Obligations
collectively being hereafter referred to as the "Guaranteed Obligations").


<PAGE>   81
                                       75

         SECTION 28.2. GUARANTY ABSOLUTE. Each of the Guarantors guarantees that
the Guaranteed Obligations will be paid strictly in accordance with the terms
hereof, regardless of any law, regulation or order now or hereafter in effect in
any jurisdiction affecting any of such terms or the rights of any Bank, any
Issuing Bank or the Administrative Agent with respect thereto. The liability of
the Guarantors under the guaranty granted under this Agreement with regard to
the Guaranteed Obligations shall be absolute and unconditional irrespective of:

                  (a) any change in the time, manner or place of payment of, or
         in any other term of, all or any of its Guaranteed Obligations or any
         other amendment or waiver of or any consent to departure from this
         Agreement or any other Loan Document (with regard to such Guaranteed
         Obligations);

                  (b) any release or amendment or waiver of or consent to
         departure from any other guaranty for all or any of its Guaranteed
         Obligations;

                  (c) any change in ownership of the Borrower;

                  (d) any acceptance of any partial payment(s) from the Borrower
         or any other Guarantor; or

                  (e) any other circumstance which might otherwise constitute a
         defense available to, or a discharge of, the Borrower in respect of its
         Obligations under any Loan Document.

         The guaranty under this Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any Guaranteed
Obligation is rescinded or must otherwise be returned by the Banks, the Issuing
Banks or the Administrative Agent upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, all as though such payment had not
been made.

         SECTION 28.3. EFFECTIVENESS; ENFORCEMENT. The guaranty under this
Agreement shall be effective and shall be deemed to be made with respect to each
Loan and each Letter of Credit as of the time it is made, issued or extended, or
becomes a Letter of Credit under this Agreement, as applicable. No invalidity,
irregularity or unenforceability by reason of any bankruptcy or similar law, or
any law or order of any government or agency thereof purporting to reduce, amend
or otherwise affect any liability of the Borrower, and no defect in or
insufficiency or want of powers of the Borrower or irregular or improperly
recorded exercise thereof, shall impair, affect, be a defense to or claim
against such guaranty. The guaranty under this Agreement is a continuing
guaranty and shall (a) survive any termination of this Agreement, and (b) remain
in full force and effect until payment in full of, and performance of, all
Guaranteed Obligations and all other amounts payable under this Agreement.
Notwithstanding anything set forth in this Section 28 to the contrary, Sanifill
shall be released from its guaranty obligations upon the satisfaction (as
determined in the Administrative Agent's judgment and evidenced by a release
executed by the Administrative Agent) of the Sanifill Convertible Subordinated
Debt. The guaranty under this Agreement is made for the benefit of the
Administrative Agent, the Issuing Banks and the Banks and their successors and
assigns, and may be enforced from time to time as often as occasion therefor may
arise and without requirement on the part of the Administrative Agent, the
Issuing


<PAGE>   82
                                       76



Banks or the Banks first to exercise any rights against the Borrower, or to
resort to any other source or means of obtaining payment of any of the said
obligations or to elect any other remedy.

         SECTION 28.4. WAIVER. Except as otherwise specifically provided in any
of the Loan Documents, each of the Guarantors hereby waives promptness,
diligence, protest, notice of protest, all suretyship defenses, notice of
acceptance and any other notice with respect to any of its Guaranteed
Obligations and the guaranty under this Agreement and any requirement that the
Banks, the Issuing Banks or the Administrative Agent protect, secure, perfect
any security interest or lien or any property subject thereto or exhaust any
right or take any action against the Borrower or any other Person. Each of the
Guarantors also irrevocably waives, to the fullest extent permitted by law, all
defenses which at any time may be available to it in respect of its Guaranteed
Obligations by virtue of any statute of limitations, valuation, stay, moratorium
law or other similar law now or hereafter in effect.

         SECTION 28.5. EXPENSES. Each of the Guarantors hereby promises to
reimburse (a) the Administrative Agent for all reasonable out-of-pocket fees and
disbursements (including all reasonable attorneys' fees), incurred or expended
in connection with the preparation, filing or recording, or interpretation of
the guaranty under this Agreement, the other Loan Documents to which such
Guarantor is a party, or any amendment, modification, approval, consent or
waiver hereof or thereof, and (b) the Administrative Agent, the Issuing Banks
and the Banks and their respective affiliates for all reasonable out-of-pocket
fees and disbursements (including reasonable attorneys' fees), incurred or
expended in connection with the enforcement of its Guaranteed Obligations
(whether or not legal proceedings are instituted). The Guarantors will pay any
taxes (including any interest and penalties in respect thereof) other than the
Banks' taxes based on overall income or profits, payable on or with respect to
the transactions contemplated by the guaranty under this Agreement, each of the
Guarantors hereby agreeing jointly and severally to indemnify each Bank with
respect thereto.

         SECTION 28.6. CONCERNING JOINT AND SEVERAL LIABILITY OF THE GUARANTORS.

                  (a) Each of the Guarantors hereby irrevocably and
         unconditionally accepts, not merely as a surety but also as a
         co-debtor, joint and several liability with the Borrower, with respect
         to the payment and performance of all of its Guaranteed Obligations
         (including, without limitation, any Guaranteed Obligations arising
         under this Section 28), it being the intention of the parties hereto
         that all such Guaranteed Obligations shall be the joint and several
         Guaranteed Obligations of such Guarantor and the Borrower without
         preferences or distinction among them.

                  (b) If and to the extent that the Borrower shall fail to make
         any payment with respect to any of its Obligations as and when due or
         to perform any of its Guaranteed Obligations in accordance with the
         terms thereof, then in each such event the applicable Guarantor will
         make such payment with respect to, or perform, such Guaranteed
         Obligation.

                  (c) The Guaranteed Obligations of each Guarantor under the
         provisions of this Section 28 constitute full recourse obligations of
         such Guarantor enforceable against such



<PAGE>   83
                                       77


         Guarantor to the full extent of its properties and assets, irrespective
         of the validity, regularity or enforceability of this Agreement or any
         other circumstance whatsoever.

                  (d) Except as otherwise expressly provided in this Agreement,
         each of the Guarantors hereby waives notice of acceptance of its joint
         and several liability, notice of any Loans made, or Letters of Credit
         issued under this Agreement, notice of any action at any time taken or
         omitted by the Administrative Agent, the Issuing Banks or the Banks
         under or in respect of any of the Guaranteed Obligations, and,
         generally, to the extent permitted by applicable law, all demands,
         notices and other formalities of every kind in connection with this
         Agreement. Each of the Guarantors hereby assents to, and waives notice
         of, any extension or postponement of the time for the payment of any of
         the Guaranteed Obligations, the acceptance of any payment of any of the
         Guaranteed Obligations, the acceptance of any partial payment thereon,
         any waiver, consent or other action or acquiescence by the
         Administrative Agent, the Issuing Banks or the Banks at any time or
         times in respect of any Default or Event of Default by the Borrower or
         the Guarantors in the performance or satisfaction of any term,
         covenant, condition or provision of this Agreement or any other Loan
         Document, any and all other indulgences whatsoever by the
         Administrative Agent, the Issuing Banks or the Banks in respect of any
         of the Guaranteed 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 Guaranteed Obligations or the addition, substitution or
         release, in whole or in part, of the Borrower or any Guarantor. Without
         limiting the generality of the foregoing, each of the Guarantors
         assents to any other action or delay in acting or failure to act on the
         part of the Banks, the Issuing Banks or the Administrative Agent with
         respect to the failure by the Borrower or any Guarantor to comply with
         its respective Obligations or Guaranteed 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 28, afford grounds for terminating, discharging or relieving
         the Guarantors, in whole or in part, from any of the Guaranteed
         Obligations under this Section 28, it being the intention of the
         Guarantors that, so long as any of the Guaranteed Obligations hereunder
         remain unsatisfied, the Guaranteed Obligations of each of the
         Guarantors under this Section 28 shall not be discharged except by
         performance and then only to the extent of such performance. The
         Guaranteed Obligations of each of the Guarantors under this Section 28
         shall not be diminished or rendered unenforceable by any winding up,
         reorganization, arrangement, liquidation, reconstruction or similar
         proceeding with respect to the Borrower or any of the Guarantors or the
         Banks, the Issuing Banks or the Administrative Agent. The joint and
         several liability of each of the Guarantors hereunder shall continue in
         full force and effect notwithstanding any absorption, merger,
         consolidation, amalgamation or any other change whatsoever in the name,
         membership, constitution or place of formation of the Borrower or the
         Guarantors, the Banks, the Issuing Banks or the Administrative Agent.

                  (e) The Guarantors shall be liable under this Section 28 only
         for the maximum amount of such liabilities that can be incurred under
         applicable law without rendering this Section 28 voidable under
         applicable law relating to fraudulent conveyance and fraudulent
         transfer, and not for any greater amount. Accordingly, if any
         obligation under any



<PAGE>   84
                                       78



         provision under this Section 28 shall be declared to be invalid or
         unenforceable in any respect or to any extent, it is the stated
         intention and agreement of the Guarantors, the Administrative Agent,
         the Issuing Banks and the Banks that any balance of the obligation
         created by such provision and all other obligations of the Guarantors
         under this Section 28 to the Banks, the Issuing Banks or the
         Administrative Agent shall remain valid and enforceable, and that all
         sums not in excess of those permitted under applicable law shall remain
         fully collectible by the Banks, the Issuing Banks and the
         Administrative Agent from the Borrower or the Guarantors, as the case
         may be.

                  (f) The provisions of this Section 28 are made for the benefit
         of the Administrative Agent, the Issuing Banks and the Banks and their
         successors and assigns, and may be enforced in good faith by them from
         time to time against the Guarantors as often as occasion therefor may
         arise and without requirement on the part of the Administrative Agent,
         the Issuing Banks or the Banks first to marshal any of their claims or
         to exercise any of their rights against the Borrower or the Guarantors
         or to exhaust any remedies available to them against the Borrower or
         the Guarantors 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 28 shall remain in effect until
         all of the Guaranteed Obligations shall have been paid in full or
         otherwise fully satisfied and the Commitments have expired and all
         outstanding Letters of Credit have expired, matured or otherwise been
         terminated. If at any time, any payment, or any part thereof, made in
         respect of any of the Guaranteed Obligations, is rescinded or must
         otherwise be restored or returned by the Banks, the Issuing Banks or
         the Administrative Agent upon the insolvency, bankruptcy or
         reorganization of the Borrower or any of the Guarantors, or otherwise,
         the provisions of this Section 28 will forthwith be reinstated in
         effect, as though such payment had not been made.

         SECTION 28.7. WAIVER. Until the final payment and performance in full
of all of the Obligations, neither of the Guarantors shall exercise and each of
the Guarantors hereby waives any rights such Guarantor may have against the
Borrower or the other Guarantor arising as a result of payment by such Guarantor
hereunder, by way of subrogation, reimbursement, restitution, contribution or
otherwise, and will not prove any claim in competition with the Administrative
Agent, the Issuing Banks or any Bank in respect of any payment hereunder in any
bankruptcy, insolvency or reorganization case or proceedings of any nature; such
Guarantor will not claim any setoff, recoupment or counterclaim against the
Borrower or the other Guarantor in respect of any liability of the Borrower to
such Guarantor; and such Guarantor waives any benefit of and any right to
participate in any collateral security which may be held by the Administrative
Agent, the Issuing Banks or any Bank.

         SECTION 28.8. SUBROGATION; SUBORDINATION. The payment of any amounts
due with respect to any indebtedness of the Borrower for money borrowed or
credit received now or hereafter owed to either of the Guarantors is hereby
subordinated to the prior payment in full of all of the Obligations. Each of the
Guarantors agrees that, after the occurrence of any default in the payment or
performance of any of the Obligations, such Guarantor will not demand, sue for
or otherwise attempt to collect any such indebtedness of the Borrower or the
other Guarantor to such Guarantor until all of the Obligations shall have been
paid in full. If, notwithstanding the



<PAGE>   85
                                       79


foregoing sentence, either of the Guarantors shall collect, enforce or receive
any amounts in respect of such indebtedness while any Obligations are still
outstanding, such amounts shall be collected, enforced and received by such
Guarantor as trustee for the Banks, the Issuing Banks and the Administrative
Agent and be paid over to the Administrative Agent at Default, for the benefit
of the Banks, the Issuing Banks, and the Administrative Agent on account of the
Obligations without affecting in any manner the liability of such Guarantor
under the other provisions hereof.

         SECTION 29. PARI PASSU TREATMENT.

                  (a) Notwithstanding anything to the contrary set forth herein,
         each payment or prepayment of principal and interest received after the
         occurrence of an Event of Default hereunder shall be distributed pari
         passu among the Banks, in accordance with the aggregate outstanding
         principal amount of the Obligations owing to each Bank divided by the
         aggregate outstanding principal amount of all Obligations.

                  (b) Following the occurrence and during the continuance of any
         Event of Default, each Bank agrees that if it shall, through the
         exercise of a right of banker's lien, setoff or counterclaim against
         any Borrower (pursuant to Section 13 or otherwise), including a secured
         claim under Section 506 of the Bankruptcy Code or other security or
         interest arising from or in lieu of, such secured claim, received by
         such Bank under any applicable bankruptcy, insolvency or other similar
         law or otherwise, obtain payment (voluntary or involuntary) in respect
         of the Notes, Loans, Reimbursement Obligations and other Obligations
         held by it (other than pursuant to Section 5.5, Section 5.6 or Section
         5.8) as a result of which the unpaid principal portion of the Notes and
         the Obligations held by it shall be proportionately less than the
         unpaid principal portion of the Notes and Obligations held by any other
         Bank, it shall be deemed to have simultaneously purchased from such
         other Bank a participation in the Notes and Obligations held by such
         other Bank, so that the aggregate unpaid principal amount of the Notes,
         Obligations and participations in Notes and Obligations held by each
         Bank shall be in the same proportion to the aggregate unpaid principal
         amount of the Notes and Obligations then outstanding as the principal
         amount of the Notes and other Obligations held by it prior to such
         exercise of banker's lien, setoff or counterclaim was to the principal
         amount of all Notes and other Obligations outstanding prior to such
         exercise of banker's lien, setoff or counterclaim; provided, however,
         that if any such purchase or purchases or adjustments shall be made
         pursuant to this Section 29 and the payment giving rise thereto shall
         thereafter be recovered, such purchase or purchases or adjustments
         shall be rescinded to the extent of such recovery and the purchase
         price or prices or adjustments restored without interest. The Borrower
         expressly consents to the foregoing arrangements and agrees that any
         Person holding such a participation in the Notes and the Obligations
         deemed to have been so purchased may exercise any and all rights of
         banker's lien, setoff or counterclaim with respect to any and all
         moneys owing by the Borrower to such Person as fully as if such Person
         had made a Loan directly to the Borrower in the amount of such
         participation.

         SECTION 30. TRANSITIONAL ARRANGEMENTS. Upon the Effective Date (a) this
Agreement shall supersede the Existing Credit Agreement in its entirety, and (b)
the parties
<PAGE>   86
                                       80




acknowledge and agree that the Pricing Table set forth herein shall be applied
retroactively to October 29, 1999 to the Loans and Letters of Credit outstanding
under the Existing Credit Agreement; and the Borrower hereby agrees to pay on
December 15, 1999 (i) any facility fees due under the Existing Credit Agreement,
(ii) any incremental amounts due as the result of such retroactive increase to
the extent not paid on or before the Effective Date, and (iii) any other amounts
due under the Existing Credit Agreement.

         SECTION 31. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

         SECTION 2.  THE SYNDICATED LOAN FACILITIES.

         SECTION 2.1.  COMMITMENT TO LEND.

                  (a) Subject to the terms and conditions set forth in this
         Agreement, each of the Banks severally agrees to lend to the Borrower
         and the Borrower may borrow, repay, and reborrow from time to time
         between the Effective Date and the Revolving Credit Maturity Date, upon
         notice by the Borrower to the Administrative Agent given in accordance
         with this Section 2, its Commitment Percentage of the Syndicated Loans
         as are requested by the Borrower; provided that the sum of the
         outstanding principal amount of the Syndicated Loans (including the
         Swing Line Loans) and the Maximum Drawing Amount of outstanding Letters
         of Credit shall not exceed the Total Commitment minus the aggregate
         amount of Competitive Bid Loans outstanding at such time.

                  (b) Each request for a Loan or Letter of Credit hereunder
         shall constitute a representation and warranty by the Borrower that the
         conditions set forth in Section 11 and Section 12, as the case may be,
         have been satisfied on the date of such request. Any unpaid
         Reimbursement Obligation shall be a Base Rate Loan, as set forth in
         Section 3.2(a).

         SECTION 2.2. FACILITY FEE. The Borrower agrees to pay to the
Administrative Agent for the account of the Banks a fee (the "Facility Fee") on
the Total Commitment equal to the Applicable Facility Rate multiplied by the
Total Commitment, provided that in the event that the Borrower exercises its
option under Section 5 to convert the outstanding Revolving Credit Loans into a
Term Loan, the Facility Fee will be equal to the aggregate principal amount of
the Term Loan multiplied by the Applicable Facility Rate. The Facility Fee shall
be payable for the period from and after the Effective Date quarterly in arrears
on the first day of each calendar quarter for the immediately preceding calendar
quarter with the first such payment commencing on January 1, 2000 and with a
final payment on the Revolving Credit Maturity Date (or on the date of
termination in full of the Total Commitment, if earlier), provided that in the
event the Borrower opts to convert its outstanding Revolving Credit Loans into a
Term Loan, the final payment shall be on the Term Loan Maturity Date (or on the
date the Term Loan is paid in full, if earlier). The Facility Fee shall be
distributed pro rata among the Banks in accordance with each Bank's Commitment
Percentage (as determined prior to the date the Borrower converts the
outstanding Revolving Credit Loans into a Term Loan, with respect to the
Facility Fee payable on the Term Loan).

         SECTION 2.3.  REDUCTION OF TOTAL COMMITMENT.

                  (a) The Borrower shall have the right at any time and from
         time to time upon three (3) Business Days' prior written notice to the
         Administrative Agent to reduce by $25,000,000 or a greater amount or
         terminate entirely, the Total Commitment, whereupon each Bank's
         Commitment shall be reduced pro rata in accordance with such Bank's
         Commitment Percentage of the amount specified in such notice or, as the
         case may be, terminated provided that at no time may (i) the Total
         Commitment be reduced to an amount less than the sum of (A) the Maximum
         Drawing Amount of all Letters of Credit, and (B) all Revolving Credit
         Loans then outstanding.

                  (b) The Total Commitment shall be automatically reduced as
         required pursuant to Sections 9.4(c) and (d), whereupon each Bank's
         Commitment shall be reduced pro rata in accordance with such Bank's
         Commitment Percentage of the amount terminated.


<PAGE>   24

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

                  (d) The Administrative Agent will notify the Banks promptly
         after receiving any notice delivered by the Borrower pursuant to this
         Section 2.3 and will distribute to each Bank a revised Schedule 1 to
         this Agreement.

         SECTION 2.4.  THE SYNDICATED NOTES.

                  (a) The Syndicated Loans shall be evidenced by separate
         promissory notes of the Borrower in substantially the form of Exhibit A
         hereto (each, a "Syndicated Note"), dated as of the Effective Date (or
         such later date at which a Bank becomes a party hereto pursuant to
         Section 21) and completed with appropriate insertions. One Syndicated
         Note shall be payable to the order of each Bank in an amount equal to
         its maximum Commitment, and shall represent the obligation of the
         Borrower to pay such Bank such principal amount or, if less, the
         outstanding principal amount of all Syndicated Loans made by such Bank,
         plus interest accrued thereon, as set forth herein.

                  (b) The Borrower irrevocably authorizes each Bank to make, or
         cause to be made, in connection with a Drawdown Date of any Syndicated
         Loan and at the time of receipt of any payment of principal on its
         Syndicated Note, an appropriate notation on such Bank's records or on
         the schedule attached to such Bank's Syndicated Note or a continuation
         of such schedule attached thereto reflecting the making of such Loan,
         or the receipt of such payment (as the case may be) and each Bank may,
         prior to any transfer of its Syndicated Note endorse on the reverse
         side thereof the outstanding principal amount of such Loans evidenced
         thereby. The outstanding amount of the Syndicated Loans set forth on
         such Bank's records 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 obligations of the Borrower hereunder or under
         such Notes to make payments of principal of or interest on any such
         Notes when due.

         SECTION 2.5.  INTEREST ON SYNDICATED LOANS.

                  (a) The outstanding principal amount of the Syndicated Loans
         shall bear interest at the rate per annum equal to (i) the Base Rate on
         Base Rate Loans, (ii) the Applicable Eurodollar Rate on Eurodollar
         Loans and (iii) the Applicable Swing Line Rate on Swing Line Loans.

                  (b) Interest shall be payable (i) monthly in arrears on the
         first Business Day of each month, with the first such payment
         commencing January 1, 2000, on Base Rate Loans, (ii) on the last day of
         the applicable Interest Period, and if such Interest Period is longer
         than three months, also on the last day of each three month period
         following the commencement of such Interest Period, on Eurodollar
         Loans, and (iii) on the Revolving Credit Maturity Date for all
         Revolving Credit Loans.


<PAGE>   25

         SECTION 2.6.  REQUESTS FOR SYNDICATED LOANS.

                  (a) The Borrower shall give to the Administrative Agent
         written notice in the form of Exhibit D hereto (or telephonic notice
         confirmed in writing or a facsimile in the form of Exhibit D hereto) of
         each Syndicated Loan requested hereunder (a "Syndicated Loan Request")
         not later than (a) 11:00 a.m. (New York time) on the proposed Drawdown
         Date of any Base Rate Loan, or (b) 11:00 a.m. (New York time) three (3)
         Eurodollar Business Days prior to the proposed Drawdown Date of any
         Eurodollar Loan. Each such Syndicated Loan Request shall specify (A)
         the principal amount of the Syndicated Loan requested, (B) the proposed
         Drawdown Date of such Syndicated Loan, (C) whether such Syndicated Loan
         requested is to be a Base Rate Loan or a Eurodollar Loan, and (D) the
         Interest Period for such Syndicated Loan, if a Eurodollar Loan. Each
         Syndicated Loan requested shall be in a minimum amount of $10,000,000.
         Each such Syndicated Loan Request shall reflect the Maximum Drawing
         Amount of all Letters of Credit outstanding and the amount of all
         Revolving Credit Loans outstanding (including Competitive Bid Loans and
         Swing Line Loans). Syndicated Loan Requests made hereunder shall be
         irrevocable and binding on the Borrower, and shall obligate the
         Borrower to accept the Syndicated Loan requested from the Banks on the
         proposed Drawdown Date.

                  (b) Each of the representations and warranties made by the
         Borrower to the Banks or the Administrative Agent in this Agreement or
         any other Loan Document shall be true and correct in all material
         respects when made and shall, for all purposes of this Agreement, be
         deemed to be repeated by the Borrower on and as of the date of the
         submission of a Syndicated Loan Request, Competitive Bid Quote Request,
         or Letter of Credit Application and on and as of the Drawdown Date of
         any Revolving Credit Loan or the date of issuance of any Letter of
         Credit (except to the extent (i) of changes resulting from transactions
         contemplated or permitted by this Agreement and the other Loan
         Documents, (ii) of changes occurring in the ordinary course of business
         that singly or in the aggregate are not materially adverse to the
         business, assets or financial condition of the Borrower and its
         Subsidiaries as a whole, or (iii) that such representations and
         warranties expressly relate only to an earlier date).

                  (c) The Administrative Agent shall promptly notify each Bank
         of each Syndicated Loan Request received by the Administrative Agent
         (i) on the proposed Drawdown Date of any Base Rate Loan, or (ii) three
         (3) Eurodollar Business Days prior to the proposed Drawdown Date of any
         Eurodollar Loan.

         SECTION 2.7. ELECTION OF EURODOLLAR RATE; NOTICE OF ELECTION; INTEREST
PERIODS; MINIMUM AMOUNTS.

                  (a) At the Borrower's option, so long as no Default or Event
         of Default has occurred and is then continuing, the Borrower may (i)
         elect to convert any Base Rate Loan or a portion thereof to a
         Eurodollar Loan, (ii) at the time of any Syndicated Loan Request,
         specify that such requested 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 Borrower give
         notice to the Administrative Agent pursuant to


<PAGE>   26

         Section 2.7(b) hereof. Upon determining any Eurodollar Rate, the
         Administrative Agent shall forthwith provide notice thereof to the
         Borrower and the Banks, and each such notice to the Borrower 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 Borrower shall
         give written, telex or facsimile notice (or telephonic notice promptly
         confirmed in a writing or a facsimile) received by the Administrative
         Agent not later than 11:00 a.m. (New York time) of its election
         pursuant to Section 2.7(a). Each such notice delivered to the
         Administrative Agent shall specify the aggregate principal amount of
         the Syndicated 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 Borrower. If the Borrower shall fail to give the
         Administrative Agent notice of its election hereunder together with all
         of the other information required by this Section 2.7(b) with respect
         to any Syndicated Loan, whether at the end of an Interest Period or
         otherwise, such Syndicated Loan shall be deemed a Base Rate Loan. The
         Administrative Agent shall promptly notify the Banks in writing (or by
         telephone confirmed in writing or by facsimile) of such election.

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

                  (d) No conversion of Loans pursuant to this Section 2.7 may
         result in Eurodollar Loans that are less than $5,000,000. In no event
         shall the Borrower have more than eight (8) different Interest Periods
         for borrowings of Eurodollar Loans outstanding at any time.

                  (e) Subject to the terms and conditions of Section 6.7 hereof,
         if any Affected Bank demands compensation under Section 6.4(c) or (d)
         with respect to any Eurodollar Loan, the Borrower may at any time, upon
         at least three (3) Business Days' prior written notice to the
         applicable Administrative Agent, elect to convert such Eurodollar Loan
         into a Base Rate Loan (on which interest and principal shall be payable
         contemporaneously with the related Eurodollar Loans of the other
         Banks). Thereafter, and until such time as the Affected Bank notifies
         the Administrative Agent that the circumstances giving rise to the
         demand for compensation under Section 6.4(c) or (d) no longer exist,
         all requests for Eurodollar Loans from such Affected Bank shall be
         deemed to be requests for Base Rate Loans. Once the Affected Bank
         notifies the Administrative Agent that such circumstances no longer
         exist, the Borrower may elect that the principal amount of each such
         Loan converted hereunder shall again bear interest as Eurodollar Loans
         beginning on the first day of the next succeeding Interest Period
         applicable to the related Eurodollar Loans of the other Banks.

         SECTION 2.8. FUNDS FOR SYNDICATED LOANS. Not later than 1:00 p.m. (New
York time) on the proposed Drawdown Date of Syndicated Loans, each of the Banks
will make available to the Administrative Agent at its Head Office, in
immediately available funds, the amount of its Commitment Percentage of the
amount of the requested Loan. Upon receipt from each Bank of such amount, and
upon receipt of the documents required by Section 11 and Section 12 and the
satisfaction of



<PAGE>   27

the other conditions set forth therein, the Administrative Agent will make
available to the Borrower the aggregate amount of such Syndicated Loans made
available by the Banks. The failure or refusal of any Bank to make available to
the Administrative Agent at the aforesaid time and place on any Drawdown Date
the amount of its Commitment Percentage of the requested Syndicated Loan shall
not relieve any other Bank from its several obligations hereunder to make
available to the Administrative Agent the amount of such Bank's Commitment
Percentage of the requested Loan.

         SECTION 2.9. MATURITY OF THE REVOLVING CREDIT LOANS AND REIMBURSEMENT
OBLIGATIONS. The Borrower promises to pay on the Revolving Credit Maturity Date,
and there shall become absolutely due and payable on the Revolving Credit
Maturity Date, all of the Revolving Credit Loans and unpaid Reimbursement
Obligations outstanding on such date, together with any and all accrued and
unpaid interest thereon and any fees and other amounts owing hereunder.

         SECTION 2.10. REQUEST FOR EXTENSION OF REVOLVING CREDIT MATURITY DATE.
The Borrower may, provided that no Default or Event of Default has occurred and
is continuing, by written notice to the Administrative Agent given not more than
sixty (60) days nor less than forty-five (45) days prior to the initial
Revolving Credit Maturity Date (the "Initial Maturity Date") request that the
Initial Maturity Date be extended to the date which is 364 days after the
Initial Maturity Date. The Administrative Agent shall notify the Banks of such
request promptly after receipt, and request each Bank to notify the
Administrative Agent of its determination to consent or not to consent to such
extension. Each Bank which makes a determination not to consent shall notify the
Administrative Agent of such determination by the thirtieth (30th) day prior to
the Initial Maturity Date (without prejudice to any Bank's right to determine
not to consent after such thirtieth (30th) day but on or before the tenth (10th)
Business Day before the Initial Maturity Date). The Borrower may take the
actions permitted by Section 6.11 to replace any Bank that fails to consent to
such extension, or reduce the Total Commitment as permitted under Section 2.3.
If the Majority Banks (including any Replacement Bank, if applicable) consent to
the extension by so notifying the Administrative Agent in writing no earlier
than ten (10) Business Days prior to the Initial Maturity Date, the Revolving
Credit Maturity Date for Revolving Credit Loans of such consenting or
Replacement Banks shall be extended for 364 days. The determination of each Bank
shall be in the sole discretion of such Bank. Each Bank shall give written
notice of its determination to consent or not to consent to such extension
pursuant to this Section 2.10, no earlier than the tenth (10th) Business Day
prior to the Initial Maturity Date. All non-consenting Banks' Revolving Credit
Loans shall be payable in full on the Initial Maturity Date, unless the Borrower
has exercised its option to term out all Revolving Credit Loans pursuant to
Section 5.1. Any Bank which fails to give written notice of its consent or
non-consent shall be deemed not to have consented to the extension hereunder.

         SECTION 2.11.  PREPAYMENTS OR REPAYMENTS OF REVOLVING CREDIT LOANS.

                  (a) Optional Prepayments: Subject to the terms and conditions
         of Section 6.7, the Borrower shall have the right, at its election, to
         repay or prepay the outstanding amount of the Revolving Credit Loans
         (other than Competitive Bid Loans), as a whole or in part, at any time
         without penalty or premium. The Borrower shall give the Administrative
         Agent no later than 11:00 a.m. (New York time) (i) on the proposed date
         of prepayment



<PAGE>   28

         or repayment of Base Rate Loans, and (ii) three (3) Eurodollar Business
         Day prior to the proposed date of prepayment or repayment of Eurodollar
         Rate Loans, written notice (or telephonic notice confirmed in writing
         or by facsimile) of any proposed prepayment or repayment pursuant to
         this Section 2.11, specifying the proposed date of prepayment or
         repayment of such Loans and the principal amount to be paid.
         Notwithstanding the foregoing, the Borrower may not prepay any
         Competitive Bid Loans. The Administrative Agent shall promptly notify
         each Bank by written notice (or telephonic notice confirmed in writing
         or by facsimile) of such notice of payment.

                  (b) Mandatory Repayments:

                                    (i) If at any time the sum of the
                           outstanding principal amount of the Revolving Credit
                           Loans plus the Maximum Drawing Amount of all
                           outstanding Letters of Credit exceeds the Total
                           Commitment, whether by reduction of the Total
                           Commitment or otherwise, then the Borrower shall
                           immediately pay the amount of such excess to the
                           Administrative Agent, (A) for application to the
                           Revolving Credit Loans, first to Syndicated Loans,
                           then to Competitive Bid Loans, subject to Section
                           6.7, or (B) if no Revolving Credit Loans shall be
                           outstanding, to be held by the Administrative Agent
                           for the benefit of the Banks as collateral security
                           for such excess Maximum Drawing Amount and the
                           Borrower hereby grants a security interest in such
                           amount to the Administrative Agent for the benefit of
                           the Banks; provided, however, that if the amount of
                           cash collateral held by the Administrative Agent
                           pursuant to this Section 2.11(b)(i) exceeds the
                           Maximum Drawing Amount required to be collateralized
                           from time to time, the Administrative Agent shall
                           return such excess to the Borrower.

                                    (ii) Payments required pursuant to Section
                           Section 9.4(c) and (d) shall be applied in the manner
                           set forth in subsection (i) above.

         SECTION 2.12.  SWING LINE LOANS; SETTLEMENTS.

                  (a) Solely for ease of administration of the Syndicated Loans,
         BKB may, but shall not be required to, fund Base Rate Loans made in
         accordance with the provisions of this Agreement ("Swing Line Loans").
         The Swing Line Loans shall be evidenced by a promissory note of the
         Borrower in substantially the form of Exhibit B hereto (the "Swing Line
         Note") and, at the discretion of BKB may be in amounts less than
         $10,000,000 provided that the outstanding amount of Swing Line Loans
         advanced by BKB hereunder shall not exceed $10,000,000 at any time.
         Each Bank shall remain severally and unconditionally liable to fund its
         pro rata share (based upon each Bank's Commitment Percentage) of such
         Swing Line Loans on each Swing Line Settlement Date and, in the event
         BKB chooses not to fund all Base Rate Loans requested on any date, to
         fund its Commitment Percentage of the Base Rate Loans requested,
         subject to satisfaction of the provisions hereof relating to the making
         of Base Rate Loans. Prior to each Swing Line Settlement, all payments
         or repayments of the principal of, and interest on, Swing Line Loans
         shall be credited to the account of BKB.


<PAGE>   29

                  (b) The Banks shall effect Swing Line Settlements on (i) the
         Business Day immediately following any day which BKB gives written
         notice to the Administrative Agent to effect a Swing Line Settlement,
         (ii) the Business Day immediately following the Administrative Agent's
         becoming aware of the existence of any Default or Event of Default, and
         (iii) the Revolving Credit Maturity Date (each such date, a "Swing Line
         Settlement Date"). One (1) Business Day prior to each such Swing Line
         Settlement Date, the Administrative Agent shall give telephonic notice
         to the Banks of (A) the respective outstanding amount of Syndicated
         Loans made by each Bank as at the close of business on the prior day,
         (B) the amount that any Bank, as applicable (a "Swing Line Settling
         Bank"), shall pay to effect a Swing Line Settlement (a "Swing Line
         Settlement Amount") and (C) the portion (if any) of the aggregate Swing
         Line Settlement Amount to be paid to each Bank. A statement of the
         Administrative Agent submitted to the Banks with respect to any amounts
         owing hereunder shall be prima facie evidence of the amount due and
         owing. Each Swing Line Settling Bank shall, not later than 1:00 p.m.
         (New York time) on each Swing Line Settlement Date, effect a wire
         transfer of immediately available funds to the Administrative Agent at
         its Head Office in the amount of such Bank's Swing Line Settlement
         Amount. The Administrative Agent shall, as promptly as practicable
         during normal business hours on each Swing Line Settlement Date, effect
         a wire transfer of immediately available funds to each Bank of the
         Swing Line Settlement Amount to be paid to such Bank. All funds
         advanced by any Bank as a Swing Line Settling Bank pursuant to this
         Section 2.12(b) shall for all purposes be treated as a Base Rate Loan
         made by such Swing Line Settling Bank to the Borrower, and all funds
         received by any Bank pursuant to this Section 2.12(b) shall for all
         purposes be treated as repayment of amounts owed by the Borrower with
         respect to Base Rate Loans made by such Bank.

                  (c) The Administrative Agent may (unless notified to the
         contrary by any Swing Line Settling Bank by 12:00 noon (New York time)
         one (1) Business Day prior to the Settlement Date) assume that each
         Swing Line Settling Bank has made available (or will make available by
         the time specified in Section 2.12(b)) to the Administrative Agent its
         Swing Line Settlement Amount, and the Administrative Agent may (but
         shall not be required to), in reliance upon such assumption, make
         available to each applicable Bank its share (if any) of the aggregate
         Swing Line Settlement Amount. If the Swing Line Settlement Amount of
         such Swing Line Settling Bank is made available to the Administrative
         Agent by such Swing Line Settling Bank on a date after such Swing Line
         Settlement Date, such Swing Line Settling Bank shall pay the
         Administrative 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 annual interest rate paid by the Administrative
         Agent for federal funds acquired by the Administrative Agent during
         each day included in such period times (ii) such Swing Line Settlement
         Amount times (iii) a fraction, the numerator of which is the number of
         days that elapse from and including such Swing Line Settlement Date to
         but not including the date on which such Swing Line Settlement Amount
         shall become immediately available to the Administrative Agent, and the
         denominator of which is 365. Upon payment of such amount such Swing
         Line Settling Bank shall be deemed to have delivered its Swing Line
         Settlement Amount on the Swing Line Settlement Date and shall become
         entitled to interest payable by the Borrower with respect to such Swing
         Line Settling Bank's Swing Line Settlement



<PAGE>   30

         Amount as if such share were delivered on the Swing Line Settlement
         Date. If such Swing Line Settlement Amount is not in fact made
         available to the Administrative Agent by such Swing Line Settling Bank
         within three (3) Business Days of such Swing Line Settlement Date, the
         Administrative Agent shall be entitled to recover such amount from the
         Borrower, with interest thereon at the Base Rate.

                  (d) After any Swing Line Settlement Date, any payment by the
         Borrower of Swing Line Loans hereunder shall be allocated among the
         Banks, in amounts determined so as to provide that after such
         application and the related Swing Line Settlement, the outstanding
         amount of Syndicated Loans of each Bank equals, as nearly as
         practicable, such Bank's Commitment Percentage of the aggregate amount
         of Syndicated Loans.

         SECTION 3.  LETTERS OF CREDIT.

         SECTION 3.1.  LETTER OF CREDIT COMMITMENTS.

                  (a) Subject to the terms and conditions hereof and the receipt
         of a Letter of Credit Application by an Issuing Bank, with a copy to
         the Administrative Agent reflecting the Maximum Drawing Amount of all
         Letters of Credit (including the requested Letter of Credit), such
         Issuing Bank, on behalf of the Banks and in reliance upon the
         representations and warranties of the Borrower contained herein and the
         agreement of the Banks contained in Section 3.1(b) hereof, agrees to
         issue Letters of Credit for the account of the Borrower (which may,
         with such Issuing Bank's consent, incorporate automatic renewals for
         periods of up to twelve (12) months), in such form as may be requested
         from time to time by the Borrower and agreed to by the Issuing Bank;
         provided, however, that, after giving effect to such request, the
         aggregate Maximum Drawing Amount of all Letters of Credit issued at any
         time shall not exceed the lesser of (i) $100,000,000 or (ii) the Total
         Commitment minus the aggregate outstanding amount of the Revolving
         Credit Loans and provided further, that no Letter of Credit shall have
         an expiration date later than five (5) Business Days prior to the
         Revolving Credit Maturity Date. The letters of credit listed in
         Schedule 3.1(a) issued by the Issuing Banks and the Transitional
         Issuing Banks under the Prior Loan Agreement shall be Letters of Credit
         under this Agreement. Letters of Credit may only be renewed or extended
         by Letters of Credit issued by Issuing Banks (other than Transitional
         Issuing Banks) hereunder.

                  (b) Each Letter of Credit shall be denominated in Dollars.
         Each Bank severally agrees that it shall be absolutely liable, without
         regard to the occurrence of any Default or Event of Default, the
         termination of the Total Commitment pursuant to Section 13.2, or any
         other condition precedent whatsoever, to the extent of such Bank's
         Commitment Percentage to reimburse the Issuing Bank on demand for the
         amount of each draft paid by the Issuing Bank under each Letter of
         Credit to the extent that such amount is not reimbursed by the Borrower
         pursuant to Section 3.2 (such agreement for a Bank being called herein
         the "Letter of Credit Participation" of such Bank). Each Bank agrees
         that its obligation to reimburse the Issuing Bank pursuant to this
         Section 3.1(b) shall not be affected in any way by any circumstance
         other than the gross negligence or willful misconduct of the Issuing
         Bank.


<PAGE>   31

                  (c) Each such reimbursement payment made by a Bank to the
         Issuing Bank shall be treated as the purchase by such Bank of a
         participating interest in the applicable 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 BORROWER. In order to
induce the Issuing Banks to issue, extend and renew each Letter of Credit, the
Borrower hereby agrees to reimburse or pay to each Issuing Bank, with respect to
each Letter of Credit issued, extended or renewed by such Issuing Bank hereunder
as follows:

                  (a) if any draft presented under any Letter of Credit is
         honored by such Issuing Bank or such Issuing Bank otherwise makes
         payment with respect thereto, the sum of (i) the amount paid by such
         Issuing Bank 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 such Issuing Bank in connection with any payment
         made by such Issuing Bank under, or with respect to, such Letter of
         Credit, provided however, if the Borrower does not reimburse such
         Issuing Bank on the Drawdown Date, such amount shall, provided that no
         Event of Default under Section 13(g) or 13(h) has occurred, become
         automatically a Syndicated Loan which is a Base Rate Loan advanced
         hereunder in an amount equal to such sum; and

                  (b) upon the Revolving Credit Maturity Date or the
         acceleration of the Reimbursement Obligations with respect to all
         Letters of Credit in accordance with Section 13, an amount equal to the
         then Maximum Drawing Amount of all Letters of Credit shall be paid by
         the Borrower to the Administrative Agent to be held as cash collateral
         for the applicable Reimbursement Obligations.

         SECTION 3.3. OBLIGATIONS ABSOLUTE. The Borrower's respective
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 Borrower may have or have had against any Issuing
Bank, any Bank or any beneficiary of a Letter of Credit, and the Borrower
expressly waives any such rights that it may have with respect thereto. The
Borrower further agrees with each Issuing Bank and the Banks that such Issuing
Bank and the Banks (i) shall not be responsible for, and the Borrower's
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 (unless due to the willful misconduct of
such Issuing Bank or any other Bank), or any dispute between or among the
Borrower and 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 Borrower against the beneficiary of any
Letter of Credit or any such transferee, and (ii) 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 except to the extent of their own willful misconduct. The Borrower agrees
that any action taken or omitted by any Issuing Bank or any Bank in good faith


<PAGE>   32

under or in connection with any Letter of Credit and the related drafts and
documents shall be binding upon the Borrower and shall not result in any
liability on the part of such Issuing Bank or any Bank (or their respective
affiliates) to the Borrower. Nothing herein shall constitute a waiver by the
Borrower of any of its rights against any beneficiary of a Letter of Credit.

         SECTION 3.4. RELIANCE BY THE ISSUING BANKS. To the extent not
inconsistent with Section 3.3, each Issuing Bank 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, facsimile, telex or teletype message, statement, order or other
document believed by such Issuing Bank in good faith 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 and other
experts selected by such Issuing Bank.

         SECTION 3.5. NOTICE REGARDING LETTERS OF CREDIT. One (1) Business Day
prior to the issuance of any Letter of Credit or amendments, extensions or
terminations thereof, the applicable Issuing Bank shall notify the
Administrative Agent of the terms of such Letter of Credit, amendment, extension
or termination. On the day of any drawing under any Letter of Credit, such
Issuing Bank shall notify the Administrative Agent of such drawing under any
Letter of Credit.

         SECTION 3.6. LETTER OF CREDIT FEE. The Borrower shall pay a fee (the
"Letter of Credit Fee") equal to the Applicable L/C Rate on the Maximum Drawing
Amount of the Letters of Credit to the Administrative Agent for the account of
the Banks, to be shared pro rata by the Banks in accordance with their
respective Commitment Percentages. The Letter of Credit Fee shall be payable
quarterly in arrears on the first day of each calendar quarter for the quarter
just ended, with the first such payment commencing January 1, 2000, and on the
Revolving Credit Maturity Date. In addition, an issuing fee (the "Issuance Fee")
with respect to each Letter of Credit to be agreed upon annually between the
Borrower and each Issuing Bank shall be payable to such Issuing Bank for its
account.

         SECTION 4.  COMPETITIVE BID LOANS.

         SECTION 4.1. THE COMPETITIVE BID OPTION. In addition to the Syndicated
Loans made pursuant to Section 2 hereof, the Borrower may request Competitive
Bid Loans pursuant to the terms of this Section 4. The Banks may, but shall have
no obligation to, make such offers and the Borrower may, but shall have no
obligation to, accept such offers in the manner set forth in this Section 4.
Notwithstanding any other provision herein to the contrary, at no time shall the
aggregate principal amount of Competitive Bid Loans outstanding at any time
exceed the Total Commitment minus the sum of (a) the aggregate outstanding
principal amount of Syndicated Loans (including the Swing Loans), plus (b) the
Maximum Drawing Amount of Letters of Credit, outstanding at such time.

         SECTION 4.2.  COMPETITIVE BID LOAN ACCOUNTS: COMPETITIVE BID NOTES.

                  (a) The obligation of the Borrower to repay the outstanding
         principal amount of any and all Competitive Bid Loans, plus interest at
         the applicable rate accrued thereon, shall be evidenced by this
         Agreement and by individual loan accounts (the "Competitive Bid Loan
         Accounts" and individually, a "Competitive Bid Loan Account")
         maintained by



<PAGE>   33

         the Administrative Agent on its books for each of the Banks, it being
         the intention of the parties hereto that, except as provided for in
         paragraph (b) of this Section 4.2, the Borrower's obligations with
         respect to Competitive Bid Loans are to be evidenced only as stated
         herein and not by separate promissory notes.

                  (b) Any Bank may at any time, and from time to time, request
         that any Competitive Bid Loans outstanding to such Bank be evidenced by
         a promissory note of the Borrower in substantially the form of Exhibit
         C hereto (each, a "Competitive Bid Note"), dated as of the Effective
         Date and completed with appropriate insertions. One Competitive Bid
         Note shall be payable to the order of each Bank in an amount equal to
         the Total Commitment, and representing the obligation of the Borrower
         to pay such Bank such principal amount or, if less, the outstanding
         principal amount of any and all Competitive Bid Loans made by such
         Bank, plus interest at the applicable Competitive Bid Rate or
         Competitive Bid Margin accrued thereon, as set forth herein. Upon
         execution and delivery by the Borrower of a Competitive Bid Note, the
         Borrower's obligation to repay any and all Competitive Bid Loans made
         to it by such Bank and all interest thereon shall thereafter be
         evidenced by such Competitive Bid Note.

                  (c) The Borrower irrevocably authorizes (i) each Bank to make
         or cause to be made, in connection with a Drawdown Date of any
         Competitive Bid Loan or at the time of receipt of any payment of
         principal on such Bank's Competitive Bid Note in the case of a
         Competitive Bid Note, and (ii) the Administrative Agent to make or
         cause to be made, in connection with a Drawdown Date of any Competitive
         Bid Loan or at the time of receipt of any payment of principal on such
         Bank's Competitive Bid Loan Account in the case of a Competitive Bid
         Loan Account, an appropriate notation on such Bank's records or on the
         schedule attached to such Bank's Competitive Bid Note or a continuation
         of such schedule attached thereto, or the Administrative Agent's
         records, as applicable, reflecting the making of the Competitive Bid
         Loan or the receipt of such payment (as the case may be) and such Bank
         may, prior to any transfer of a Competitive Bid Note, endorse on the
         reverse side thereof the outstanding principal amount of Competitive
         Bid Loans evidenced thereby. The outstanding amount of the Competitive
         Bid Loans set forth on such Bank's record or the Administrative Agent's
         records, as applicable, 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 obligations of the Borrower hereunder to make
         payments of principal of or interest on any Competitive Bid Loan when
         due.

         SECTION 4.3. COMPETITIVE BID QUOTE REQUEST; INVITATION FOR COMPETITIVE
BID QUOTES.

                  (a) When the Borrower wishes to request offers to make
         Competitive Bid Loans under this Section 4, it shall transmit to the
         Administrative Agent by telex or facsimile a Competitive Bid Quote
         Request substantially in the form of Exhibit H hereto (a "Competitive
         Bid Quote Request") so as to be received no later than 1:00 p.m. (New
         York time) (x) five (5) Eurodollar Business Days prior to the requested
         Drawdown Date in the case of a LIBOR Competitive Bid Loan (a "LIBOR
         Competitive Bid Loan") or (y)



<PAGE>   34

         one (1) Business Day prior to the requested Drawdown Date in the case
         of an Absolute Competitive Bid Loan (an "Absolute Competitive Bid
         Loan"), specifying:

                           (i) the requested Drawdown Date (which must be a
                  Eurodollar Business Day in the case of a LIBOR Competitive Bid
                  Loan or a Business Day in the case of an Absolute Competitive
                  Bid Loan);

                           (ii) the aggregate amount of such Competitive Bid
                  Loans, which shall be $10,000,000 or larger multiple of
                  $1,000,000;

                           (iii) the duration of the Interest Period(s)
                  applicable thereto, subject to the provisions of the
                  definition of Interest Period; and

                           (iv) whether the Competitive Bid Quotes requested are
                  for LIBOR Competitive Bid Loans or Absolute Competitive Bid
                  Loans.

         The Borrower may request offers to make Competitive Bid Loans for more
         than one Interest Period in a single Competitive Bid Quote Request. No
         new Competitive Bid Quote Request shall be given until the Borrower has
         notified the Administrative Agent of its acceptance or non-acceptance
         of the Competitive Bid Quotes relating to any outstanding Competitive
         Bid Quote Request.

                  (b) Promptly upon receipt of a Competitive Bid Quote Request,
         the Administrative Agent shall send to the Banks by telecopy or
         facsimile transmission an Invitation for Competitive Bid Quotes
         substantially in the form of Exhibit I hereto, which shall constitute
         an invitation by the Borrower to each Bank to submit Competitive Bid
         Quotes in accordance with this Section 4.

         SECTION 4.4. ALTERNATIVE MANNER OF PROCEDURE. If, after receipt by the
Administrative Agent and each of the Banks of a Competitive Bid Quote Request
from the Borrower in accordance with Section 4.3, the Administrative Agent or
any Bank shall be unable to complete any procedure of the auction process
described in Section Section 4.5 through 4.6 (inclusive) due to the inability of
such Person to transmit or receive communications through the means specified
therein, such Person may rely on telephonic notice for the transmission or
receipt of such communications. In any case where such Person shall rely on
telephone transmission or receipt, any communication made by telephone shall, as
soon as possible thereafter, be followed by written confirmation thereof.

         SECTION 4.5.  SUBMISSION AND CONTENTS OF COMPETITIVE BID QUOTES.

                  (a) Each Bank may, but shall be under no obligation to, submit
         a Competitive Bid Quote containing an offer or offers to make
         Competitive Bid Loans in response to any Competitive Bid Quote Request.
         Each Competitive Bid Quote must comply with the requirements of this
         Section 4.5 and must be submitted to the Administrative Agent by telex

         Section 23 not later than (x) 2:00 p.m. (New York time) on the fourth

         Bid

         Administrative Agent in its capacity as a Bank only if it submits its
         Competitive Bid Quote to the Borrower not later than (x) one hour prior
         to the deadline for the other Banks, in the case of a LIBOR Competitive
         Bid Loan or (y) 15 minutes prior to the deadline for the other Banks,
         in the case of an Absolute Competitive Bid Loan. Subject to the
         provisions of Sections 11 and 12 hereof, any Competitive Bid Quote so
         made shall be irrevocable except with the written consent of the
         Administrative Agent given on the instructions of the Borrower.

                  (b) Each Competitive Bid Quote shall be in substantially the
         form of Exhibit J hereto and shall in any case specify:

                           (i)  the proposed Drawdown Date;

                           (ii) the principal amount of the Competitive Bid Loan
                  for which each proposal is being made, which principal amount
                  (w) may be greater than or less than the Commitment of the
                  quoting Bank, (x) must be $5,000,000 or a larger multiple of
                  $1,000,000, (y) may not exceed the aggregate principal amount
                  of Competitive Bid Loans for which offers were requested and
                  (z) may be subject to an aggregate limitation as to the
                  principal amount of Competitive Bid Loans for which offers
                  being made by such quoting Bank may be accepted;

                           (iii) the Interest Period(s) for which Competitive
                  Bid Quotes are being submitted;

                           (iv) in the case of a LIBOR Competitive Bid Loan, the
                  margin above or below the applicable LIBOR Rate (the
                  "Competitive Bid Margin") offered for each such Competitive
                  Bid Loan, expressed as a percentage (specified to the nearest
                  1/10,000th of 1%) to be added to or subtracted from such LIBOR
                  Rate;

                           (v) in the case of an Absolute Competitive Bid Loan,
                  the rate of interest per annum (specified to the nearest
                  1/10,000th of 1%) (the "Competitive Bid Rate") offered for
                  each such Absolute Competitive Bid Loan; and

                           (vi) the identity of the quoting Bank.

         A Competitive Bid Quote may include up to five separate offers by the
         quoting Bank with respect to each Interest Period specified in the
         related Invitation for Competitive Bid Quotes.

                  (c)  Any Competitive Bid Quote shall be disregarded if it:

<PAGE>   36

                           (iv) arrives after the time set forth in Section
                  4.5(a) hereof.

         SECTION 4.6. NOTICE TO BORROWER. The Administrative Agent shall
promptly notify the Borrower of the terms (x) of any Competitive Bid Quote
submitted by a Bank that is in accordance with Section 4.5 and (y) of any
Competitive Bid Quote that amends, modifies or is otherwise inconsistent with a
previous Competitive Bid Quote submitted by such Bank with respect to the same
Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall
be disregarded by the Administrative Agent unless such subsequent Competitive
Bid Quote is submitted solely to correct a manifest error in such former
Competitive Bid Quote. The Administrative Agent's notice to the Borrower shall
specify (A) the aggregate principal amount of Competitive Bid Loans for which
offers have been received for each Interest Period specified in the related
Competitive Bid Quote Request, (B) the respective principal amounts and
Competitive Bid Margins or Competitive Bid Rates, as the case may be, so
offered, and the identity of the respective Banks submitting such offers, and
(C) if applicable, limitations on the aggregate principal amount of Competitive
Bid Loans for which offers in any single Competitive Bid Quote may be accepted.

         SECTION 4.7. ACCEPTANCE AND NOTICE BY BORROWER AND ADMINISTRATIVE
AGENT. Not later than 11:00 a.m. (New York time) on (x) the third Eurodollar
Business Day prior to the proposed Drawdown Date, in the case of a LIBOR
Competitive Bid Loan or (y) the proposed Drawdown Date, in the case of an
Absolute Competitive Bid Loan, the Borrower shall notify the Administrative
Agent of its acceptance or non-acceptance of each Competitive Bid Quote in
substantially the form of Exhibit K hereto. The Borrower may accept any
Competitive Bid Quote in whole or in part; provided that:

                  (i) the aggregate principal amount of each Competitive Bid
         Loan may not exceed the applicable amount set forth in the related
         Competitive Bid Quote Request;

                  (ii) acceptance of offers may only be made on the basis of
         ascending Competitive Bid Margins or Competitive Bid Rates, as the case
         may be, and

                  (iii) the Borrower may not accept any offer that is described
         in subsection 4.5(c) or that otherwise fails to comply with the
         requirements of this Agreement.

The Administrative Agent shall promptly notify each Bank which submitted a
Competitive Bid Quote of the Borrower's acceptance or non-acceptance thereof. At
the request of any Bank which submitted a Competitive Bid Quote and with the
consent of the Borrower, the Administrative Agent will promptly notify all Banks
which submitted Competitive Bid Quotes of (a) the aggregate principal amount of,
and (b) the range of Competitive Bid Rates or Competitive Bid Margins of, the
accepted Competitive Bid Loans for each requested Interest Period.

         SECTION 4.8. ALLOCATION BY ADMINISTRATIVE AGENT. If offers are made by
two or more Banks with the same Competitive Bid Margin or Competitive Bid Rate,
as the case may be, for a greater aggregate principal amount than the amount in
respect of which offers are accepted for the related Interest Period, the
principal amount of Competitive Bid Loans in respect of which such offers are
accepted shall be allocated by the Administrative Agent among such Banks as




<PAGE>   37

nearly as possible (in such multiples, not less than $1,000,000, as the
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determination by the Administrative Agent of
the amounts of Competitive Bid Loans shall be conclusive in the absence of
manifest error.

         SECTION 4.9. FUNDING OF COMPETITIVE BID LOANS. If, on or prior to the
Drawdown Date of any Competitive Bid Loan, the Total Commitment has not
terminated in full and if, on such Drawdown Date, the applicable conditions of
Sections 11 and 12 hereof are satisfied, the Bank or Banks whose offers the
Borrower has accepted will fund each Competitive Bid Loan so accepted. Such Bank
or Banks will make such Competitive Bid Loans by crediting the Administrative
Agent for further credit to the Borrower's specified account with the
Administrative Agent, in immediately available funds not later than 1:00 p.m.
(New York time) on such Drawdown Date.

         SECTION 4.10. FUNDING LOSSES. If, after acceptance of any Competitive
Bid Quote pursuant to Section 4, the Borrower (i) fails to borrow any
Competitive Bid Loan so accepted on the date specified therefor, or (ii) repays
the outstanding amount of the Competitive Bid Loan prior to the last day of the
Interest Period relating thereto, the Borrower shall indemnify the Bank making
such Competitive Bid Quote or funding such Competitive Bid Loan against any loss
or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Bank to fund or maintain such unborrowed
Competitive Bid Loans, including, without limitation compensation as provided in
Section 6.7.

         SECTION 4.11. REPAYMENT OF COMPETITIVE BID LOANS; INTEREST. The
principal of each Competitive Bid Loan shall become absolutely due and payable
by the Borrower on the last day of the Interest Period relating thereto, and the
Borrower hereby absolutely and unconditionally promises to pay to the
Administrative Agent for the account of the relevant Banks at or before 1:00
p.m. (New York time) on the last day of the Interest Periods relating thereto
the principal amount of all such Competitive Bid Loans, plus interest thereon at
the applicable rates. The Competitive Bid Loans shall bear interest at the rate
per annum specified in the applicable Competitive Bid Quotes. Interest on the
Competitive Bid Loans shall be payable (a) on the last day of the applicable
Interest Periods, and if any such Interest Period is longer than three months,
also on the last day of the third month following the commencement of such
Interest Period, and (b) on the Revolving Credit Maturity Date for all Revolving
Credit Loans. Subject to the terms of this Agreement, the Borrower may make
Competitive Bid Quote Requests with respect to new borrowings of any amounts so
repaid prior to the Revolving Credit Maturity Date.

         SECTION 5.  THE TERM LOAN.

         SECTION 5.1. CONVERSION OF REVOLVING CREDIT LOANS; THE TERM LOAN.
Subject to the terms and conditions set forth in this Agreement, including,
without limitation, the satisfaction of the conditions set forth in Section 12
hereof and the execution and delivery by the Borrower of the Term Notes to the
Banks, on the Revolving Credit Maturity Date the aggregate amount of the
outstanding Revolving Credit Loans at such date shall, at the option of the
Borrower, be converted into a Term Loan in the aggregate principal amount equal
to the aggregate outstanding principal balance of the Revolving Credit Loans on
such date, held severally by the Banks in accordance with their Commitment
Percentages and the Commitments hereunder shall terminate.



<PAGE>   38

The Term Loan outstanding after conversion shall be evidenced by the separate
Term Notes (the "Term Notes") of the Borrower payable to the order of each Bank,
each dated as of the Revolving Credit Maturity Date and in substantially the
form of Exhibit L hereto, completed with appropriate insertions. On the
Revolving Credit Maturity Date, the Borrower shall pay to the Administrative
Agent for the pro rata accounts of the Banks, all interest accrued to such date
on the Revolving Credit Loans, any Facility Fees and other fees payable to the
Administrative Agent and the Banks hereunder and, as soon as reasonably
practicable after such payment, each Bank shall surrender to the Borrower its
Revolving Credit Notes against receipt of its Term Note evidencing the amount of
the outstanding Revolving Credit Loans so converted. The term-out option granted
herein may be exercised only once (either on the Initial Maturity Date or the
extended Revolving Credit Maturity Date) and must term out all then existing
Revolving Credit Loans.

         SECTION 5.2. THE TERM NOTES. Each Term Note shall represent the
obligation of the Borrower to pay to such Bank the principal amount of the Term
Loan evidenced by the Term Note plus interest accrued thereon, as set forth
below. The Borrower irrevocably authorizes each Bank to make or cause to be made
a notation on such Bank's Term Note Record reflecting the original principal
amount of such Bank's Commitment Percentage of the Term Loan and, at or about
the time of such Bank's receipt of any principal payment on such Bank's Term
Note, an appropriate notation on such Bank's Term Note Record reflecting such
payment. The aggregate unpaid amount set forth on such Bank's Term Note 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 on such Bank's Term Note Record shall not affect the obligations of the
Borrower hereunder or under any Term Note to make payments of principal of and
interest on any Term Note when due.

         SECTION 5.3. REPAYMENTS OF THE TERM LOAN. The Borrower promises to pay
to the Administrative Agent for the account of the Banks the principal amount of
the Term Loan on the Term Loan Maturity Date in an amount equal to the unpaid
balance of the Term Loan.

         SECTION 5.4. OPTIONAL PREPAYMENT OF TERM LOAN. The Borrower shall have
the right at any time to prepay the Term Loans on or before the Term Loan
Maturity Date, as a whole, or in part, upon not less than one (1) Business Day
prior written notice to the Administrative Agent, without premium or penalty,
provided that (a) each partial prepayment shall be in the principal amount of
$5,000,000 or an integral multiple thereof, (b) any portion of any Eurodollar
Rate Loan which has been prepaid on any day other than the last day of the
Interest Period relating thereto shall be subject to the payment by the Borrower
of any applicable costs associated with such prepayment as set forth in Section
2.11 hereof, and (c) each partial prepayment shall be allocated among the Banks,
in proportion, as nearly as practicable, to the respective outstanding amount of
each Bank's Term Note, with adjustments to the extent practicable to equalize
any prior prepayments not exactly in proportion. Any prepayment of principal of
the Term Loan shall include all interest accrued on such amount to the date of
prepayment. No amount repaid with respect to the Term Loan may be reborrowed.


<PAGE>   39

         SECTION 5.5.  INTEREST ON TERM LOAN.

                  SECTION 5.5.1. NOTIFICATION BY BORROWER. The Borrower shall
         notify the Administrative Agent, such notice to be irrevocable, at
         least three (3) Eurodollar Business Days prior to the Drawdown Date of
         the Term Loan if all or any portion of the Term Loan is to be a
         Eurodollar Rate Loan. After the Term Loan has been made, the provisions
         of Section 2 shall apply mutatis mutandis with respect to all or any
         portion of the Term Loan so that the Borrower may have the same
         interest rate options and interest rates with respect to all or any
         portion of the Term Loan as it would be entitled to with respect to the
         Syndicated Loans.

                  SECTION 5.5.2. AMOUNTS, ETC. Any portion of the Term Loan
         which is a Eurodollar Loan relating to any Interest Period shall be in
         the amount of $5,000,000 or a whole multiple or $1,000,000 in excess
         thereof. No Interest Period relating to the Term Loan or any portion
         thereof which is a Eurodollar Loan shall extend beyond the Term Loan
         Maturity Date.

         SECTION 6.  PROVISIONS RELATING TO ALL LOANS AND LETTERS OF CREDIT.

         SECTION 6.1.  PAYMENTS.

                  (a) All payments of principal, interest, Reimbursement
         Obligations, fees (other than the Issuance Fee) and any other amounts
         due hereunder or under any of the other Loan Documents shall be made to
         the Administrative Agent at its Head Office in immediately available
         funds by 11:00 a.m. (New York time) on any due date. Subject to the
         provisions of Section 30, if a payment is received by the
         Administrative Agent at or before 1:00 p.m. (New York time) on any
         Business Day, the Administrative Agent shall on the same Business Day
         transfer in immediately available funds, as applicable, to (1) each of
         the Banks, their pro rata portion of such payment in accordance with
         their respective Commitment Percentages, in the case of payments with
         respect to Syndicated Loans, Letters of Credit and the Term Loan, (2)
         BKB in the case of payments with respect to Swing Line Loans, and (3)
         the appropriate Bank(s), in the case of payments with respect to
         Competitive Bid Loans. If such payment is received by the
         Administrative Agent after 1:00 p.m. (New York time) on any Business
         Day, such transfer shall be made by the Administrative Agent to the
         applicable Bank(s) on the next Business Day. In the event that the
         Administrative Agent fails to make such transfer to any Bank as set
         forth above, the Administrative Agent shall pay to such Bank 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 such Bank for funds acquired by such Bank during
         each day included in such period, times (ii) the amount (A) equal to
         such Bank's Commitment Percentage of such payment in the case of
         payments under clause (1) above, or (B) of such payment to which such
         Bank is entitled in the case of payments with respect to Competitive
         Bid Loans and Swing Line Loans, times (iii) a fraction, the numerator
         of which is the number of days that elapse from and including the date
         of payment to and including the date on which the amount due to such
         Bank shall become immediately available to such Bank, and the
         denominator of which is 365. A statement of such Bank submitted to the
         applicable Administrative Agent with respect to any



<PAGE>   40

         amounts owing under this paragraph shall be prima facie evidence of the
         amount due and owing to such Bank by the Administrative Agent.

                  (b) Each Bank that is not incorporated or organized under the
         laws of the United States of America or a state thereof or the District
         of Columbia (a "Non-U.S. Bank") agrees that, prior to the first date on
         which any payment is due to it hereunder, it will deliver to the
         Borrower and the Administrative Agent two duly completed copies of
         United States Internal Revenue Service Form W-8BEN or W-8ECI or
         successor applicable form, as the case may be, certifying in each case
         that such Non-U.S. Bank is entitled to receive payments under this
         Agreement and the Notes payable to it, without deduction or withholding
         of any United States federal income taxes. Each Non-U.S. Bank that so
         delivers a Form W-8BEN or W-8ECI pursuant to the preceding sentence
         further undertakes to deliver to each of the Borrower and the
         Administrative Agent two further copies of Form W-8BEN or W-8ECI or
         successor applicable form, or other manner of certification, as the
         case may be, on or before the date that any such letter or form expires
         or becomes obsolete or after the occurrence of any event requiring a
         change in the most recent form previously delivered by it to the
         Borrower, and such extensions or renewals thereof as may reasonably be
         requested by the Borrower, certifying in the case of a Form W-8BEN or
         W-8ECI that such Non-U.S. Bank is entitled to receive payments under
         this Agreement and the Notes without deduction or withholding of any
         United States federal income taxes, unless in any such case an event
         (including, without limitation, any change in treaty, law or
         regulation) has occurred prior to the date on which any such delivery
         would otherwise be required which renders all such forms inapplicable
         or which would prevent such Non-U.S. Bank from duly completing and
         delivering any such form with respect to it and such Non-U.S. Bank
         advises the Borrower that it is not capable of receiving payments
         without any deduction or withholding of United States federal income
         tax.

                  (c) The Borrower shall not be required to pay any additional
         amounts to any Non-U.S. Bank in respect of United States Federal
         withholding tax pursuant to Section 18 to the extent that (i) the
         obligation to withhold amounts with respect to United States Federal
         withholding tax existed on the date such Non-U.S. Bank became a party
         to this Agreement or, with respect to payments to a different lending
         office designated by the Non-U.S. Bank as its applicable lending office
         (a "New Lending Office"), the date such Non-U.S. Bank designated such
         New Lending Office with respect to a Loan; provided, however, that this
         clause (i) shall not apply to any transferee or New Lending Office as a
         result of an assignment, transfer or designation made at the request of
         the Borrower; and provided further, however, that this clause (i) shall
         not apply to the extent the indemnity payment or additional amounts any
         transferee, or Bank through a New Lending Office, would be entitled to
         receive without regard to this clause (i) do not exceed the indemnity
         payment or additional amounts that the Person making the assignment or
         transfer to such transferee, or Bank making the designation of such New
         Lending Office, would have been entitled to receive in the absence of
         such assignment, transfer or designation; or (ii) the obligation to pay
         such additional amounts would not have arisen but for a failure by such
         Non-U.S. Bank to comply with the provisions of paragraph (b) above.


<PAGE>   41

                  (d) Notwithstanding the foregoing, each Bank agrees to use
         reasonable efforts (consistent with legal and regulatory restrictions)
         to change its lending office to avoid or to minimize any amounts
         otherwise payable under Section 18 in each case solely if such change
         can be made in a manner so that such Bank, in its sole determination,
         suffers no legal, economic or regulatory disadvantage.

         SECTION 6.2. COMPUTATIONS. Except as otherwise expressly provided
herein, all computations of interest, Facility Fees, Letter of Credit Fees or
other fees shall be based on a 360-day year and paid for the actual number of
days elapsed, except that computations based on the Base Rate shall be based on
a 365 or 366, as applicable, day year and paid for the actual number of days
elapsed. 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 payment
shall be extended to the next succeeding Business Day, and interest shall accrue
during such extension; provided that for any Interest Period for any Eurodollar
Loan if such next succeeding Business Day falls in the next succeeding calendar
month or after the Revolving Credit Maturity Date, or Term Loan Maturity Date,
as the case may be, it shall be deemed to end on the next preceding Business
Day.

         SECTION 6.3. ILLEGALITY; INABILITY TO DETERMINE EURODOLLAR RATE.
Notwithstanding any other provision of this Agreement (other than Section 6.9),
if (a) the introduction of, any change in, or any change in the interpretation
of, any law or regulation applicable to any Bank or the Administrative Agent
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 Administrative Agent to perform its obligations in respect of any Eurodollar
Loans, or (b) if any Bank or the Administrative Agent, as applicable, 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 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 Administrative Agent in any Eurodollar interbank market, or (iii) the
Eurodollar Rate does not or will not accurately reflect the cost to the Bank or
the Administrative Agent of obtaining or maintaining the Eurodollar Loans during
any Interest Period, then such Bank or the Administrative Agent shall promptly
give telephonic, telex or cable notice of such determination to the Borrower
(which notice shall be conclusive and binding upon the Borrower). Upon such
notification by the Bank or the Administrative Agent, the obligation of the
Banks and the Administrative Agent to make Eurodollar Loans shall be suspended
until the Banks or the Administrative Agent, as the case may be, determine that
such circumstances no longer exist, and to the extent permitted by law 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 to such former Eurodollar Loans.

         SECTION 6.4. 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


<PAGE>   42

central bank or other fiscal, monetary or other authority, whether or not having
the force of law) shall:

                  (a) subject such Bank to any tax, levy, impost, duty, charge,
         fee, deduction or withholding of any nature with respect to this
         Agreement, the other Loan Documents, such Bank's Commitment or the
         Loans (other than taxes based upon or measured by the income or profits
         of such Bank imposed by the jurisdiction of its incorporation or
         organization, or the location of its lending office); or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits of such Bank imposed by the
         jurisdiction of its incorporation or organization, or the location of
         its lending office) of payments to such Bank of the principal or of the
         interest on any Loans or any other amounts payable to such Bank under
         this Agreement or the other Loan Documents; or

                  (c) except as provided in Section 6.5 or as otherwise
         reflected in the Base Rate, the Eurodollar Rate, or the applicable rate
         for Competitive Bid Loans, impose or increase or render applicable
         (other than to the extent specifically provided for elsewhere in this
         Agreement) any special deposit, reserve, assessment, liquidity, capital
         adequacy or other similar requirements (whether or not having the force
         of law) against assets held by, or deposits in or for the account of,
         or loans by, or commitments of, an office of any Bank with respect to
         this Agreement, the other Loan Documents, such Bank's Commitment or the
         Loans; or

                  (d) impose on such Bank any other conditions or requirements
         with respect to this Agreement, the other Loan Documents, the Loans,
         such Bank's Commitment or any class of loans or commitments of which
         any of the Loans or such Bank's Commitment 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
                  or such Bank's Commitment or issuing or participating in
                  Letters of Credit;

                           (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 the Reimbursement Obligations;
                  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 Borrower
                  hereunder,

                  then, and in each such case, the Borrower will, upon demand
         made by such Bank at any time and from time to time as often as the
         occasion therefore may arise (which demand shall be accompanied by a
         statement setting forth the basis of such demand which shall be
         conclusive absent manifest error), pay such reasonable additional
         amounts



<PAGE>   43

         as will be sufficient to compensate such Bank for such additional
         costs, reduction, payment or foregone interest or other sum.

         SECTION 6.5. CAPITAL ADEQUACY. If any Bank shall have determined that,
after the date hereof, (i) the adoption of any applicable law, rule or
regulation regarding capital adequacy, or any change in any such law, rule, or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, or (ii) compliance by such Bank or the
Administrative Agent or any corporation controlling such Bank or the
Administrative Agent with any law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law and including any
determination by such central bank or other governmental authority that for
purposes of capital adequacy requirements the Commitments hereunder do not
constitute commitments with an original maturity of one year or less) of any
such entity regarding capital adequacy, has or would have the effect of reducing
the rate of return on capital of such Bank (or any corporation controlling such
Bank) as a consequence of such Bank's obligations hereunder to a level below
that which such Bank (or any corporation controlling such Bank) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank, the Borrower shall pay to such Bank such additional amount or
amounts as will, in such Bank's reasonable determination, fairly compensate such
Bank (or any corporation controlling such Bank) for such reduction. Each Bank
shall allocate such cost increases among its customers in good faith and on an
equitable basis.

         SECTION 6.6. CERTIFICATE. A certificate setting forth the additional
amounts payable pursuant to Section 6.4 or Section 6.5 and a reasonable
explanation of such amounts which are due, submitted by any Bank to the
Borrower, shall be conclusive, absent manifest error, that such amounts are due
and owing.

         SECTION 6.7. EURODOLLAR AND COMPETITIVE BID INDEMNITY. The Borrower
agrees to indemnify the Banks and the Administrative Agent and to hold them
harmless from and against any reasonable loss, cost or expense that any such
Bank and the Administrative Agent may sustain or incur as a consequence of (a)
the default by the Borrower in payment of the principal amount of or any
interest on any Eurodollar Loans or Competitive Bid Loans as and when due and
payable, including any such loss or expense arising from interest or fees
payable by any Bank or the Administrative Agent to lenders of funds obtained by
it in order to maintain its Eurodollar Loans or Competitive Bid Loans, (b) the
default by the Borrower in making a borrowing of a Eurodollar Loan or
Competitive Bid Loan or conversion of a Eurodollar Loan or a prepayment of a
Eurodollar or Competitive Bid Loan other than pursuant to Section 2.5(b) after
the Borrower has given (or is deemed to have given) a Syndicated Loan Request, a
notice pursuant to Section 2.7 or a Notice of Acceptance/Rejection of
Competitive Bid Quote(s), or a notice pursuant to Section 2.11, and (c) the
making of any payment of a Eurodollar Loan or Competitive Bid Loan, or the
making of any conversion of any Eurodollar Loan to a Base Rate Loan on a day
that is not the last day of the applicable Interest Period with respect thereto.
Such loss, cost, or reasonable expense shall include an amount equal to the
excess, if any, as reasonably determined by each Bank of (i) its


<PAGE>   44

cost of obtaining the funds for (A) the Eurodollar Loan being paid, prepaid,
converted, not converted, reallocated, or not borrowed, as the case may be
(based on the Eurodollar Rate), or (B) the Competitive Bid Loan being paid,
prepaid, or not borrowed, as the case may be (based on the applicable interest
rate) for the period from the date of such payment, prepayment, conversion, or
failure to borrow or convert, as the case may be, to the last day of the
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for the Loan which would have commenced on the date of such
failure to borrow) over (ii) the amount of interest (as reasonably determined by
such Bank) that would be realized by such Bank in reemploying the funds so paid,
prepaid, converted, or not borrowed, converted, or prepaid for such period or
Interest Period, as the case may be, which determinations shall be conclusive
absent manifest error.

         SECTION 6.8. 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 compounded monthly and payable on demand at a rate per annum equal to
the Base Rate plus 2%, until such amount shall be paid in full (after as well as
before judgment).

         SECTION 6.9. INTEREST LIMITATION. Notwithstanding any other term of
this Agreement or the Notes, any other Loan Document 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 the Notes 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 by such
Bank under applicable laws (including, to the extent applicable, the provisions
of Section 5197 of the Revised Statutes of the United States of America, as
amended, and 12 U.S.C. Section 85, as amended).

         SECTION 6.10. REASONABLE EFFORTS TO MITIGATE. Each Bank agrees that as
promptly as practicable after it becomes aware of the occurrence of an event or
the existence of a condition that would cause it to be affected under Sections
6.3, 6.4 or 6.5, such Bank will give notice thereof to the Borrower, with a copy
to the Administrative Agent and, to the extent so requested by the Borrower and
not inconsistent with such Bank's internal policies, such Bank shall use
reasonable efforts and take such actions as are reasonably appropriate if as a
result thereof the additional moneys which would otherwise be required to be
paid to such Bank pursuant to such sections would be materially reduced, or the
illegality or other adverse circumstances which would otherwise require a
conversion of such Loans or result in the inability to make such Loans pursuant
to such sections would cease to exist, and in each case if, as determined by
such Bank in its sole discretion, the taking of such actions would not adversely
affect such Loans or such Bank or otherwise be disadvantageous to such Bank.

         SECTION 6.11. REPLACEMENT OF BANKS. If any Bank (an "Affected Bank")
(i) makes demand upon the Borrower for (or if the Borrower is otherwise required
to pay) amounts pursuant to Sections 6.4 or 6.5, (ii) is unable to make or
maintain Eurodollar Loans as a result of a condition described in Section 6.3,
(iii) defaults in its obligation to make Loans or to participate in Letters of
Credit in accordance with the terms of this Agreement (such Bank being referred
to as a "Defaulting Bank") or (iv) fails to agree to extend the Revolving Credit
Maturity Date pursuant to Section 2.10, the Borrower may, within 90 days of
receipt of such demand, notice (or the occurrence



<PAGE>   45

of such other event causing the Borrower to be required to pay such
compensation or causing Section 6.3 to be applicable), or default, as the case
may be, by notice (a "Replacement Notice") in writing to the Administrative
Agent and such Affected Bank (A) request the Affected Bank to cooperate with the
Borrower in obtaining a replacement bank satisfactory to the Administrative
Agent and the Borrower (the "Replacement Bank") as provided herein, but none of
such Banks shall be under an obligation to find a Replacement Bank; (B) request
the non-Affected Banks to acquire and assume all of the Affected Bank's Loans
and Commitment, and to participate in Letters of Credit 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 Administrative 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, and to participate in Letters of Credit then such Affected Bank
shall, so long as no Event of Default shall have occurred and be continuing,
assign, in accordance with Section 21, all of its Commitment, Loans, Notes and
other rights and obligations under this 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 (x) 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 (y) prior to any such
assignment, the Borrower shall have paid to such Affected Bank all amounts
properly demanded and unreimbursed under Sections 6.4, 6.5 and 6.7. Upon the
effective date of such assignment, the Borrower shall issue replacement Notes to
such Replacement Bank and/or non-Affected Banks, as the case may be, and such
Replacement Bank shall become a "Bank" for all purposes under this Agreement and
the other Loan Documents.

         SECTION 6.12. ADVANCES BY ADMINISTRATIVE AGENT. The Administrative
Agent may (unless earlier notified to the contrary by any Bank by 12:00 noon
(New York time) one (1) Business Day prior to any Drawdown Date) assume that
each Bank has made available (or will before the end of such Business Day make
available) to the Administrative Agent the amount of such Bank's Commitment
Percentage with respect to the Loans (or, in the case of Competitive Bid Loans,
the amount of such Bank's accepted offers of such Loans, if any) to be made on
such Drawdown Date, and the Administrative Agent may (but shall not be required
to), in reliance upon such assumption, make available to the Borrower a
corresponding amount. If any Bank makes such amount available to the
Administrative Agent on a date after such Drawdown Date, such Bank shall pay the
Administrative 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 annual interest rate paid by the Administrative Agent for
federal funds acquired by the Administrative Agent during each day included in
such period times (ii) the amount equal to such Bank's Commitment Percentage of
such Syndicated Loan (or, in the case of Competitive Bid Loans and Swing Line
Loans, the amount of such Bank's accepted offer of such Competitive Bid Loans,
if any, and portion of such Swing Line Loans) or the Term Loan, as the case may
be, times (iii) a fraction, the numerator of which is the number of days that
elapse from and including such Drawdown Date to but not including the date on
which the amount equal to such Bank's Commitment Percentage of such Loans, or
the amount of such Bank's accepted offers of such Competitive Bid Loans, if any,
and portion of Swing Line Loans, shall become immediately



<PAGE>   46

available to the Administrative Agent, and the denominator of which is 365. A
statement of the Administrative Agent submitted to such Bank with respect to any
amounts owing under this paragraph shall be prima facie evidence of the amount
due and owing to the Administrative Agent by such Bank. If such amount is not in
fact made available to the Administrative Agent by such Bank within three (3)
Business Days of such Drawdown Date, the Administrative Agent shall be entitled
to recover such amount from such Borrower, with interest thereon at the
applicable rate per annum.

         SECTION 7. REPRESENTATIONS AND WARRANTIES. The Borrower (and the
Guarantor, where applicable) represents and warrants to the Banks that:

         SECTION 7.1. CORPORATE AUTHORITY.

                  (a) INCORPORATION; GOOD STANDING. The Borrower and each of its
         Subsidiaries (i) is duly organized, validly existing and in good
         standing under the laws of its respective jurisdiction of formation,
         (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 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 the Borrower and its
         Subsidiaries as a whole.

                  (b) AUTHORIZATION. The execution, delivery and performance of
         its Loan Documents and the transactions contemplated hereby and thereby
         (i) are within the corporate authority of the Borrower and the
         Guarantor, (ii) have been duly authorized by all necessary corporate
         proceedings on the part of each of the Borrower and the Guarantor,
         (iii) do not conflict with or result in any breach or contravention of
         any provision of law, statute, rule or regulation to which any of the
         Borrower or the Guarantor or any of their Subsidiaries is subject or
         any judgment, order, writ, injunction, license or permit applicable to
         the Borrower, the Guarantor or any of their Subsidiaries so as to
         materially adversely affect the assets, business or any activity of the
         Borrower, the Guarantor and their Subsidiaries as a whole, and (iv) do
         not conflict with any provision of the corporate charter or bylaws of
         the Borrower, the Guarantor or any Subsidiary or any agreement or other
         instrument binding upon the Borrower, the Guarantor or any of their
         Subsidiaries.

                  (c) ENFORCEABILITY. The execution, delivery and performance of
         the Loan Documents by the Borrower and the Guarantor will result in
         valid and legally binding obligations of the Borrower and the Guarantor
         enforceable against them 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.


<PAGE>   47

         SECTION 7.2. GOVERNMENTAL AND OTHER APPROVALS. The execution, delivery
and performance of the Loan Documents by the Borrower and the Guarantor and the
consummation by the Borrower and the Guarantor of the transactions contemplated
hereby and thereby do not require any approval or consent of, or filing with,
any governmental agency or authority or other third party other than those
already obtained and those required after the date hereof in connection with the
Borrower's and its Subsidiaries' performance of their covenants contained in
Sections 8, 9 and 10 hereof.

         SECTION 7.3. TITLE TO PROPERTIES; LEASES. The Borrower and its
Subsidiaries own all of the assets reflected in the consolidated balance sheet
as at the Interim Balance Sheet Date or acquired since that date (except
property and assets operated under capital leases or sold or otherwise disposed
of in the ordinary course of business since that date), subject to no mortgages,
Capitalized Leases, conditional sales agreements, title retention agreements,
liens or other encumbrances except Permitted Liens.

         SECTION 7.4. FINANCIAL STATEMENTS; SOLVENCY.

                  (a) There have been furnished to the Banks consolidated
         balance sheets of the Borrower and its Subsidiaries dated the Balance
         Sheet Date and consolidated statements of operations for the fiscal
         periods then ended, certified by the Accountants. In addition, there
         have been furnished to the Banks consolidated balance sheets of the
         Borrower and its Subsidiaries dated the Interim Balance Sheet Date and
         the related consolidated statements of operation for the fiscal quarter
         ending on the Interim Balance Sheet Date. All said balance sheets and
         statements of operations have been prepared in accordance with GAAP
         (but, in the case of any of such financial statements which are
         unaudited, only to the extent GAAP is applicable to interim unaudited
         reports), fairly present the financial condition of the Borrower and
         its Subsidiaries on a consolidated basis as at the close of business on
         the dates thereof and the results of operations for the periods then
         ended, subject, in the case of unaudited interim financial statements,
         to changes resulting from audit and normal year-end adjustments and to
         the absence of complete footnotes. There are no contingent liabilities
         of the Borrower and its Subsidiaries involving material amounts, known
         to the officers of the Borrower or Guarantor which have not been
         disclosed in said balance sheets and the related notes thereto or
         otherwise in writing to the Banks.

                  (b) The Borrower and its Subsidiaries on a consolidated basis
         (both before and after giving effect to the transactions contemplated
         by this Agreement) are 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
         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 7.5. NO MATERIAL CHANGES, ETC. Since the Interim Balance Sheet
Date, there have occurred no material adverse changes in the consolidated
financial condition, business, assets or liabilities (contingent or otherwise)
of the Borrower and its Subsidiaries, taken together, as shown on or reflected
in the consolidated balance sheets of the Borrower and its Subsidiaries as at
the Interim Balance Sheet Date, or the consolidated statements of income for the
period then



<PAGE>   48

ended other than changes in the ordinary course of business which have not had
any material adverse effect either individually or in the aggregate on the
financial condition, business, assets or liabilities (contingent or otherwise)
of the Borrower and its Subsidiaries, taken together. Since the Interim Balance
Sheet Date, there have not been any Distributions other than as permitted by
Section 9.5 hereof.

         SECTION 7.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. The Borrower and
each of its Subsidiaries possess all franchises, patents, copyrights,
trademarks, trade names, licenses and permits, and rights in respect of the
foregoing, adequate for the conduct of their business substantially as now
conducted (other than those the absence of which would not have a material
adverse effect on the business, operations or financial condition of the
Borrower and its Subsidiaries as a whole) without known conflict with any rights
of others other than a conflict which would not have a material adverse effect
on the financial condition, business or assets of the Borrower and its
Subsidiaries as a whole.

         SECTION 7.7. LITIGATION. Except as set forth on Schedule 7.7 or in the
Disclosure Documents, there are no actions, suits, proceedings or investigations
of any kind pending or, to the knowledge of the Borrower or any of its
Subsidiaries, threatened against the Borrower or any of its Subsidiaries before
any court, tribunal or administrative agency or board which, either in any case
or in the aggregate, could reasonably be expected to have a material adverse
effect on the financial condition, business, or assets of the Borrower and its
Subsidiaries, considered as a whole, or materially impair the right of the
Borrower and its Subsidiaries, considered 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 to which the Borrower or any of its Subsidiaries is a
party, or any action taken or to be taken pursuant hereto or thereto.

         SECTION 7.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower
nor any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Borrower's or such Subsidiary's officers has or could reasonably
be expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Borrower and its Subsidiaries, considered
as a whole. Neither the Borrower nor any of its Subsidiaries is a party to any
contract or agreement which in the judgment of the Borrower's or its
Subsidiary's officers has or could reasonably be expected to have any materially
adverse effect on the financial condition, business or assets of the Borrower
and its Subsidiaries, considered as a whole, except as otherwise reflected in
adequate reserves as required by GAAP.

         SECTION 7.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the
Borrower nor any of its Subsidiaries is (a) violating any provision of its
charter documents or by-laws or (b) violating any agreement or instrument to
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 (in the case of such agreements or
such instruments) reasonably be expected to result in the imposition of
substantial penalties or


<PAGE>   49

materially and adversely affect the financial condition, business or assets of
the Borrower and its Subsidiaries, considered as a whole.

         SECTION 7.10. TAX STATUS. The Borrower and its Subsidiaries have filed
all federal, state, provincial and territorial income and all other tax returns,
reports and declarations (or obtained extensions with respect thereto) required
by applicable law to be filed by them (unless and only to the extent that the
Borrower or such Subsidiary has set aside on its books provisions reasonably
adequate for the payment of all unpaid and unreported taxes as required by
GAAP); and have paid all taxes and other governmental assessments and charges
(other than taxes, assessments and other governmental charges imposed by
jurisdictions other than the United States, Canada or any political subdivision
thereof which in the aggregate are not material to the financial condition,
business or assets of the Borrower or such Subsidiary on an individual basis or
of the Borrower and its Subsidiaries on a consolidated basis) 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, as required by
GAAP, 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. Except to the extent contested in the
manner permitted in the preceding sentence, there are no unpaid taxes in any
material amount claimed by the taxing authority of any jurisdiction to be due
and owing by the Borrower or any Subsidiary, nor do the officers of the Borrower
or any of its Subsidiaries know of any basis for any such claim.

         SECTION 7.11. NO EVENT OF DEFAULT. (a) No Default or Event of Default
has occurred hereunder and is continuing, and (b) no "Default" or "Event of
Default" (as defined in the Revolving Credit Facility or the European Credit
Facilities, respectively) under the Revolving Credit Facility or the European
Credit Facilities, respectively, has occurred and is continuing, or would be
created by the incurrence of Indebtedness under this Agreement.

         SECTION 7.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the
Borrower nor any of its Subsidiaries 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.

         SECTION 7.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except as permitted
by Section 9.2 of this Agreement, there is no Indebtedness senior to the
Obligations, and there is no effective 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 the Borrower or any of its Subsidiaries
or right thereunder.

         SECTION 7.14.  EMPLOYEE BENEFIT PLANS.

                  SECTION 7.14.1. IN GENERAL. Each Employee Benefit Plan has
         been maintained and operated in compliance in all material respects
         with the provisions of ERISA and/or all Applicable Canadian Pension
         Legislation, as applicable, and, to the extent applicable, the



<PAGE>   50

         Code, including but not limited to the provisions thereunder respecting
         prohibited transactions. Promptly upon the request of any Bank or the
         Administrative Agent, the Borrower will furnish to the Administrative
         Agent the most recently completed annual report, Form 5500, with all
         required attachments, and actuarial statement required to be submitted
         under Section 103(d) of ERISA, with respect to each Guaranteed Pension
         Plan.

                  SECTION 7.14.2. TERMINABILITY OF WELFARE PLANS. Under each
         Employee Benefit Plan which is an employee welfare benefit plan within
         the meaning of Section 3(1) or Section 3(2)(B) of ERISA, no benefits
         are due unless the event giving rise to the benefit entitlement occurs
         prior to plan termination (except as required by Title I, Part 6 of
         ERISA) . The Borrower or an ERISA Affiliate, as appropriate, 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
         the Borrower or such ERISA Affiliate without liability to any Person.

                  SECTION 7.14.3. GUARANTEED PENSION PLANS. 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. No liability to the PBGC (other than required
         insurance premiums, all of which have been paid) has been incurred by
         the Borrower or any ERISA Affiliate with respect to any Guaranteed
         Pension Plan (other than Terminated Plans) and there has not been any
         ERISA Reportable Event, or any other event or condition which presents
         a material risk of termination of any Guaranteed Pension Plan by the
         PBGC. Other than with respect to the Terminated Plans, 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.

                  SECTION 7.14.4. MULTIEMPLOYER PLANS. Neither the 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. Neither the 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 that any Multiemployer Plan intends to terminate or has
         been terminated under Section 4041A of ERISA.

         SECTION 7.15. ENVIRONMENTAL COMPLIANCE. The Borrower and its
Subsidiaries have taken all necessary steps to investigate the past and present
condition and usage of the Real Property and the operations conducted by the
Borrower and its Subsidiaries and, based upon such diligent investigation, have
determined that, except as set forth on Schedule 7.15 or in the Disclosure
Documents:


<PAGE>   51

                  (a) Neither the Borrower, its Subsidiaries, nor any operator
         of their 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 the Resource Conservation and Recovery Act
         ("RCRA"), the Comprehensive Environmental Response, Compensation and
         Liability Act of 1980 as amended ("CERCLA"), the Superfund Amendments
         and Reauthorization Act of 1986 ("SARA"), the Federal Clean Water Act,
         the Federal Clean Air Act, the Toxic Substances Control Act, or any
         applicable international, federal, state, provincial, territorial or
         local statute, regulation, ordinance, order or decree relating to
         health, safety, waste transportation or disposal, or the environment
         (the "Environmental Laws"), which violation, individually or in the
         aggregate, would have a material adverse effect on the business, assets
         or financial condition of the Borrower and its Subsidiaries on a
         consolidated basis.

                  (b) Except with respect to any such matters which individually
         or in the aggregate would not reasonably be expected to have a material
         adverse effect on the business, assets or financial condition of the
         Borrower and its Subsidiaries on a consolidated basis, neither the
         Borrower nor any of its Subsidiaries has received notice from any third
         party including, without limitation: any federal, state, provincial,
         territorial or local governmental authority, (i) that any one of them
         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, excluding household hazardous waste ("Hazardous
         Substances"), which any one of them has generated, transported or
         disposed of, has been found at any site at which a federal, state,
         provincial, territorial or local agency or other third party has
         conducted or has ordered that the Borrower or any of its Subsidiaries
         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) (i) No portion of the Real Property or other assets of the
         Borrower and its Subsidiaries has been used for the handling,
         processing, storage or disposal of Hazardous Substances except in
         accordance with applicable Environmental Laws, except as would not
         reasonably be expected to have a material adverse effect on the
         business, assets or financial condition of the Borrower and its
         Subsidiaries on a consolidated basis; (ii) in the course of any
         activities conducted by the Borrower, its Subsidiaries, or operators of
         the Real Property or other assets of the Borrower and its Subsidiaries,
         no Hazardous Substances have been generated or are being used on such
         properties except in accordance with applicable Environmental Laws,
         except for occurrences that would not have a material adverse effect on
         the business, assets or financial condition of the



<PAGE>   52

         Borrower and its Subsidiaries on a consolidated basis; (iii) there have
         been no unpermitted Releases or threatened Releases of Hazardous
         Substances on, upon, into or from the Real Property or other assets of
         the Borrower or its Subsidiaries, which Releases would have a material
         adverse effect on the value of such properties; (iv) to the best of the
         Borrower's and its Subsidiaries' knowledge, there have been no Releases
         on, upon, from or into any real property in the vicinity of the Real
         Property or other assets of the Borrower or its Subsidiaries which,
         through soil or groundwater contamination, may have come to be located
         on, and which would reasonably be expected to have a material adverse
         effect on the value of, such properties; and (v) in addition, any
         Hazardous Substances that have been generated on the Real Property or
         other assets of the Borrower or its Subsidiaries 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 have been and are, to the best
         of the Borrower's and its Subsidiaries' knowledge, operating in
         compliance with such permits and applicable Environmental Laws.

                  (d) None of the Real Property or other assets of the Borrower
         or its Subsidiaries or any of the stock (or assets) being acquired with
         proceeds of Loans 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 7.16. TRUE COPIES OF CHARTER AND OTHER DOCUMENTS. Each of the
Borrower and the Guarantor has furnished the Administrative Agent as of the
Effective Date, true and complete copies of (a) all charter and other
incorporation documents (together with any amendments thereto) and (b) by-laws
(together with any amendments thereto).

         SECTION 7.17. DISCLOSURE. No representation or warranty made by the
Borrower or the Guarantor in this Agreement or in any agreement, instrument,
document, certificate, statement or letter furnished to the Banks or the
Administrative Agent by or on behalf of or at the request of the Borrower and
the Guarantor in connection with any of the transactions contemplated by the
Loan Documents contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained
therein not misleading in light of the circumstances in which they are made.

         SECTION 7.18. PERMITS AND GOVERNMENTAL AUTHORITY. All permits (other
than those the absence of which would not have a material adverse effect on the
business, operations or financial condition of the Borrower and its Subsidiaries
as a whole) required for the construction and operation of all landfills
currently owned or operated by the Borrower or any of its Subsidiaries have been
obtained and remain in full force and effect and are not subject to any appeals
or further proceedings or to any unsatisfied conditions that may allow material
modification or revocation. Neither the Borrower nor any of its Subsidiaries,
nor, to the knowledge of the Borrower and its Subsidiaries, the holder of such
permits is in violation of any such permits, except for any violation which
would not have a material adverse effect on the business, operations or
financial condition of the Borrower and its Subsidiaries as a whole.


<PAGE>   53

         SECTION 7.19. YEAR 2000 COMPLIANCE. The Borrower and its Subsidiaries
have (i) reviewed the areas within their businesses and operations which could
be adversely affected by failure to become "Year 2000 Compliant" (i.e. that
computer applications, imbedded microchips and other systems used by the
Borrower or any of its Subsidiaries or any of their material vendors or
customers, will be able properly to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999), (ii) developed a detailed plan and timetable to become Year
2000 Compliant in a timely manner, and (iii) committed adequate resources to
support the Year 2000 plan of the Borrower and its Subsidiaries. Based upon such
review, the Borrower reasonably believes that the Borrower and its Subsidiaries,
as well as their material vendors and customers, will become "Year 2000
Compliant" in a timely manner except to the extent that failure to do so will
not have any materially adverse effect on the business or financial condition of
the Borrower or any of its Subsidiaries.

         SECTION 7.20. USE OF PROCEEDS. The proceeds of the Loans shall be used
for general corporate purposes.

         SECTION 8. AFFIRMATIVE COVENANTS OF THE BORROWER. The Borrower agrees
that, so long as any Obligation or any Letter of Credit is outstanding or the
Banks have any obligation to make Loans, or any Issuing Bank has any obligation
to issue, extend or renew any Letters of Credit hereunder, or the Banks have any
obligations to reimburse any Issuing Bank for drawings honored under any Letter
of Credit, it shall, and shall cause its Subsidiaries to, comply with the
following covenants:

         SECTION 8.1. PUNCTUAL PAYMENT. The Borrower 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 Agreement
and the other Loan Documents, all in accordance with the terms of this Agreement
and such other Loan Documents.

         SECTION 8.2. MAINTENANCE OF U.S. OFFICE. The Borrower will maintain its
chief executive offices at Houston, Texas, or at such other place in the United
States of America as the Borrower shall designate upon 30 days' prior written
notice to the Administrative Agent.

         SECTION 8.3. RECORDS AND ACCOUNTS. The Borrower will, and will cause
each of its Subsidiaries to, keep true and accurate records and books of account
in which full, true and correct entries will be made in accordance with GAAP and
with the requirements of all regulatory authorities and maintain adequate
accounts and reserves for all taxes (including income taxes), depreciation,
depletion, obsolescence and amortization of its properties, all other
contingencies, and all other proper reserves.

         SECTION 8.4. FINANCIAL STATEMENTS, CERTIFICATES AND INFORMATION. The
Borrower will deliver to the Banks:

                  (a) as soon as practicable, but, in any event not later than
         92 days after the end of each fiscal year of the Borrower, the
         consolidated balance sheet of the Borrower and its Subsidiaries as at
         the end of such year, consolidated statements of cash flows, and the
         related consolidated statements of operations, each setting forth in
         comparative form the figures for the previous fiscal year, all such
         consolidated financial statements to be in



<PAGE>   54

         reasonable detail, prepared, in accordance with GAAP and, with respect
         to the consolidated financial statements, certified by
         PricewaterhouseCoopers LLP or Arthur Andersen LLP or by other
         independent auditors selected by the Borrower and reasonably
         satisfactory to the Banks (the "Accountants"). In addition,
         simultaneously therewith, the Borrower shall provide the Banks with a
         written statement from such Accountants to the effect that they have
         read a copy of this Agreement, and that, in making the examination
         necessary to said certification, they have obtained no knowledge of any
         Default or Event of Default, or, if such 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;

                  (b) as soon as practicable, but in any event not later than 47
         days after the end of each of the first three fiscal quarters of each
         fiscal year of the Borrower, copies of the consolidated balance sheet
         and statement of operations of the Borrower and its Subsidiaries as at
         the end of such quarter, subject to year-end adjustments, and the
         related consolidated statement of cash flows, all in reasonable detail
         and prepared in accordance with GAAP (to the extent GAAP is applicable
         to interim unaudited financial statements) with a certification by the
         principal financial or accounting officer of the Borrower (the "CFO or
         the CAO") that the consolidated financial statements are prepared in
         accordance with GAAP (to the extent GAAP is applicable to interim
         unaudited financial statements) and fairly present the consolidated
         financial condition of the Borrower and its Subsidiaries on a
         consolidated basis as at the close of business on the date thereof and
         the results of operations for the period then ended, it being
         understood that no such statement need be accompanied by complete
         footnotes;

                  (c) simultaneously with the delivery of the financial
         statements referred to in (a) and (b) above, a certificate in the form
         of Exhibit F hereto (the "Compliance Certificate") signed by the CFO or
         the CAO or the Borrower's corporate treasurer, stating that the
         Borrower and its Subsidiaries are in compliance with the covenants
         contained in Sections 8, 9 and 10 hereof as of the end of the
         applicable period and setting forth in reasonable detail computations
         evidencing such compliance with respect to the covenants contained in
         Sections 9.1(d), 9.3, 9.4, 9.5, and 10 hereof and that no Default or
         Event of Default exists, provided that if the Borrower shall at the
         time of issuance of such Compliance Certificate or at any other time
         obtain knowledge of any Default or Event of Default, the Borrower shall
         include in such certificate or otherwise deliver forthwith to the Banks
         a certificate specifying the nature and period of existence thereof and
         what action the Borrower proposes to take with respect thereto;

                  (d) 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 Borrower's
         and its Subsidiaries' stockholders generally; and

                  (e) from time to time such other financial data and other
         information as the Banks may reasonably request.

         The Borrower hereby authorizes each Bank to disclose any information
obtained pursuant to this Agreement to all appropriate governmental regulatory
authorities where required



<PAGE>   55

by law; provided, however, 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 Borrower has or may have under the federal Right to Financial Privacy
Act of 1978, as in effect from time to time, except as to matters specifically
permitted therein.

         SECTION 8.5. EXISTENCE AND CONDUCT OF BUSINESS. The Borrower will, and
will cause each Subsidiary, to do or cause to be done all things necessary to
preserve and keep in full force and effect its existence, rights and franchises;
and effect and maintain its foreign qualifications (except where the failure of
the Borrower or any Subsidiary to remain so qualified would not materially
adversely impair the financial condition, business or assets of the Borrower and
its Subsidiaries on a consolidated basis), licensing, domestication or
authorization except as terminated by its Board of Directors in the exercise of
its reasonable judgment; provided that such termination would not have a
material adverse effect on the financial condition, business or assets of the
Borrower and its Subsidiaries on a consolidated basis. The Borrower will not,
and will cause its Subsidiaries not to, become obligated under any contract or
binding arrangement which, at the time it was entered into, would materially
adversely impair the financial condition, business or assets of the Borrower and
its Subsidiaries, on a consolidated basis. The Borrower will, and will cause
each Subsidiary to, continue to engage primarily in the businesses now conducted
by it and in related businesses.

         SECTION 8.6. MAINTENANCE OF PROPERTIES. The Borrower will, and will
cause its Subsidiaries to, 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 (ordinary wear and tear excepted) and supplied with all
necessary equipment and cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Borrower and its Subsidiaries 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 section shall prevent the
Borrower or any of its Subsidiaries from discontinuing the operation and
maintenance of any of its properties if such discontinuance is, in the judgment
of the Borrower or such Subsidiary, desirable in the conduct of its or their
business and which does not in the aggregate materially adversely affect the
financial condition, business or assets of the Borrower and its Subsidiaries on
a consolidated basis.

         SECTION 8.7. INSURANCE. The Borrower will, and will cause its
Subsidiaries to, 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 Borrower and its Subsidiaries, in amounts substantially
similar to the existing coverage policies maintained by the Borrower and its
Subsidiaries, copies of which have been provided to the Administrative Agent. In
addition, the Borrower will furnish from time to time, upon any Bank's request,
a summary of the insurance coverage of the Borrower and its Subsidiaries, which
summary shall be in form and substance satisfactory to the Banks and, if
requested by any of the Banks, will furnish to the Administrative Agent and such
Bank copies of the applicable policies.


<PAGE>   56

         SECTION 8.8. TAXES. The Borrower will, and will cause its Subsidiaries
to, 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
jurisdictions other than the United States, Canada or any political subdivision
thereof, which in the aggregate are not material to the business, financial
conditions, or assets of the Borrower and its Subsidiaries on a consolidated
basis) imposed upon it and its real properties, sales and activities, or any
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 of its property; 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 the Borrower or such Subsidiary shall have set aside on its books
adequate reserves with respect thereto as required by GAAP; and provided,
further, that the Borrower or such Subsidiary 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 8.9. INSPECTION OF PROPERTIES, BOOKS AND CONTRACTS. The
Borrower will, and will cause its Subsidiaries to, permit the Administrative
Agent or any Bank or any of their designated representatives, upon reasonable
notice, to visit and inspect any of the properties of the Borrower and its
Subsidiaries, to examine the books of account of the Borrower and its
Subsidiaries, or contracts (and to make copies thereof and extracts therefrom),
and to discuss the affairs, finances and accounts of the Borrower and its
Subsidiaries with, and to be advised as to the same by, their officers, all at
such times and intervals as may be reasonably requested.

         SECTION 8.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES AND PERMITS;
MAINTENANCE OF MATERIAL LICENSES AND PERMITS. The Borrower will, and will cause
each Subsidiary to, (i) comply with the provisions of its charter documents and
by-laws; (ii) comply in all material respects with all agreements and
instruments by which it or any of its properties may be bound; (iii) comply with
all applicable laws and regulations (including Environmental Laws), decrees,
orders, judgments, licenses and permits, including, without limitation, all
environmental permits ("Applicable Requirements"), except where noncompliance
with such Applicable Requirements would not reasonably be expected to have a
material adverse effect in the aggregate on the consolidated financial
condition, properties or businesses of the Borrower and its Subsidiaries; (iv)
maintain all material operating permits for all landfills now owned or hereafter
acquired; and (v) dispose of hazardous waste only at licensed disposal
facilities operating, to the best of the Borrower's or such Subsidiary's
knowledge after reasonable inquiry, in compliance with Environmental Laws. If at
any time 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 Borrower or any Subsidiary may fulfill any of its
obligations hereunder or under any other Loan Document, the Borrower will
immediately take or cause to be taken all reasonable steps within the power of
the Borrower or such Subsidiary to obtain such authorization, consent, approval,
permit or license and furnish the Banks with evidence thereof.

         SECTION 8.11. ENVIRONMENTAL INDEMNIFICATION. The Borrower covenants and
agrees that it will indemnify and hold the Banks, the Issuing Banks and the
Administrative Agent and their respective affiliates, and each of the
representatives, agents and officers of each of the foregoing,



<PAGE>   57

harmless from and against any and all claims, expense, damage, loss or liability
incurred by the Banks, the Issuing Banks or the Administrative Agent (including
all costs of legal representation incurred by the Banks, the Issuing Banks or
the Administrative Agent) relating to (a) any Release or threatened Release of
Hazardous Substances on the Real Property; (b) any violation of any
Environmental Laws or Applicable Requirements with respect to conditions at the
Real Property or other assets of the Borrower or its Subsidiaries, or the
operations conducted thereon; or (c) the investigation or remediation of offsite
locations at which the Borrower, any of its Subsidiaries, or their predecessors
are alleged to have directly or indirectly Disposed of Hazardous Substances. It
is expressly acknowledged by the Borrower that this covenant of indemnification
shall survive the payment of the Loans and Reimbursement Obligations and
satisfaction of all other Obligations hereunder and shall inure to the benefit
of the Banks, the Issuing Banks, the Administrative Agent and their affiliates,
successors and assigns.

         SECTION 8.12. FURTHER ASSURANCES. The Borrower and the Guarantor will
cooperate with the Administrative Agent and execute such further instruments and
documents as the Administrative Agent shall reasonably request to carry out to
the Banks' satisfaction the transactions contemplated by this Agreement.

         SECTION 8.13. NOTICE OF POTENTIAL CLAIMS OR LITIGATION. The Borrower
shall 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 against the Borrower or any of its Subsidiaries wherein
the potential liability is in excess of $25,000,000 or which questions the
validity or enforceability of any Loan Document, together with a copy of each
such complaint or other notice received by the Borrower or any of its
Subsidiaries if requested by the Administrative Agent.

         SECTION 8.14. NOTICE OF CERTAIN EVENTS CONCERNING INSURANCE AND
ENVIRONMENTAL CLAIMS.

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

                  (b) The Borrower will promptly, and in any event within ten
         (10) Business Days of the Borrower's obtaining knowledge thereof,
         notify the Banks in writing of any of the following events:

                           (i) upon the Borrower's or any Subsidiary's obtaining
                  knowledge of any violation of any Environmental Law regarding
                  the Real Property or the Borrower's or any Subsidiary's
                  operations which violation could have a material adverse
                  effect on the business, financial condition, or assets of the
                  Borrower and its Subsidiaries on a consolidated basis;

                           (ii) upon the Borrower's or any Subsidiary's
                  obtaining knowledge of any potential or known Release, or
                  threat of Release, of any Hazardous Substance at, from, or
                  into the Real Property which could materially affect the
                  business,



<PAGE>   58

                  financial condition, or assets of the Borrower and its
                  Subsidiaries on a consolidated basis;

                           (iii) upon the Borrower's or any Subsidiary's receipt
                  of any notice of any material violation of any Environmental
                  Law 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 any
                  federal, state, provincial, territorial or local governmental
                  officials) and including notice of any formal inquiry,
                  proceeding, demand, investigation or other action with regard
                  to (A) the Borrower's, any Subsidiary'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 the Borrower, any Subsidiary, or
                  its predecessors are alleged to have directly or indirectly
                  Disposed of Hazardous Substances, and with respect to which
                  the liability associated therewith could be reasonably
                  expected to exceed $30,000,000; or

                           (iv) upon the Borrower's or any Subsidiary's
                  obtaining knowledge that any expense or loss which
                  individually or in the aggregate exceeds $30,000,000 has been
                  incurred by such governmental authority in connection with the
                  assessment, containment, removal or remediation of any
                  Hazardous Substances with respect to which the Borrower or any
                  Subsidiary may be liable or for which a lien may be imposed on
                  the Real Property.

         SECTION 8.15. NOTICE OF DEFAULT. The Borrower will promptly notify the
Banks in writing of the occurrence of any Default or Event of Default. If any
Person shall give any notice or take any other action in respect of a claimed
default (whether or not constituting an Event of Default) under this Agreement
or any other note, evidence of indebtedness, indenture or other obligation
evidencing indebtedness in excess of $25,000,000 as to which the Borrower or any
of its Subsidiaries is a party or obligor, whether as principal or surety, the
Borrower shall forthwith upon obtaining actual knowledge thereof give written
notice thereof to the Banks, describing the notice of action and the nature of
the claimed default.

         SECTION 8.16. USE OF PROCEEDS.

                  (a) GENERALLY: The proceeds of the Loans shall be used for
         general corporate purposes. No proceeds of the Loans shall be used in
         any way that will violate Regulations U or X of the Board of Governors
         of the Federal Reserve System.

                  (b) INELIGIBLE SECURITIES: No portion of the proceeds of any
         Loan is to be used, and no portion of any Letter of Credit is to be
         obtained, for the purpose of (i) 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, (ii) knowingly
         purchasing, or providing credit support for the purchase of, during the
         underwriting or placement period, any Ineligible Securities being

         making, or providing credit support for the making of, payments of
         principal or interest on Ineligible Securities underwritten or
         privately placed by a Section


<PAGE>   59

         20 Subsidiary and issued by or for the benefit of the Borrower or any
         Subsidiary or other affiliate of the Borrower.

         SECTION 8.17. CERTAIN TRANSACTIONS. Except as disclosed in the
Disclosure Documents prior to the Effective Date, and except for arm's length
transactions pursuant to which the Borrower or any Subsidiary makes payments in
the ordinary course of business upon terms no less favorable than the Borrower
or such Subsidiary could obtain from third parties, none of the officers,
directors, or employees or any other affiliate of the Borrower or any Subsidiary
are presently or shall be a party to any transaction with the Borrower or any
Subsidiary (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 the Borrower or any
Subsidiary, 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 9. CERTAIN NEGATIVE COVENANTS OF THE BORROWER. The Borrower
agrees that, so long as any Obligation or Letter of Credit is outstanding or the
Banks have any obligation to make Loans or any Issuing Bank has any obligation
to issue, extend or renew any Letters of Credit hereunder, or the Banks have any
obligation to reimburse any Issuing Bank for drawings honored under any Letter
of Credit, it shall, and shall cause its Subsidiaries to, comply with the
following covenants:

         SECTION 9.1. RESTRICTIONS ON INDEBTEDNESS. Neither the Borrower nor any
of its Subsidiaries shall become or be a guarantor or surety of, or otherwise
create, incur, assume, or be or remain liable, contingently or otherwise, with
respect to any Indebtedness, or become or be responsible in any manner (whether
by agreement to purchase any obligations, stock, assets, goods or services, or
to supply or advance any funds, assets, goods or services or otherwise) with
respect to any Indebtedness of any other Person, or incur any Indebtedness other
than:

                  (a) Indebtedness arising under this Agreement or the other
         Loan Documents;

                  (b) (i) Indebtedness incurred by the Borrower or any
         Subsidiary with respect to any suretyship or performance bond incurred
         in the ordinary course of its business, and undrawn landfill closure
         bonds; and

                      (ii) Guarantees of the Subsidiaries' obligations to
         governmental authorities in lieu of the posting of any landfill closure
         bonds;

                  (c) Unsecured Indebtedness of the Borrower (and any guarantee
         thereof by Guarantor), including commercial paper, which is pari passu
         or subordinated to the Obligations; provided that there does not exist
         a Default or Event of Default at the time of the incurrence of such
         Indebtedness and no Default or Event of Default would be created by the
         incurrence of such Indebtedness;

                  (d) (i) Indebtedness of the Borrower's Subsidiaries (other
         than of the Guarantor incurred prior to July 16, 1998), (ii) secured
         Indebtedness of the Borrower,


<PAGE>   60

         (iii) Indebtedness with respect to drawn landfill closure bonds of the
         Borrower's Subsidiaries (other than of the Guarantor), and (iv)
         Indebtedness with respect to Permitted Receivables Transactions (other
         than of the Guarantor); provided that the aggregate amount of all such
         Indebtedness in this Section 9.1(d) shall not exceed 15% of
         Consolidated Tangible Assets at any time;

                  (e) Indebtedness of the Guarantor listed in Schedule 9.1(e) on
         the terms and conditions existing on July 16, 1998, provided that any
         extension, renewal or refinancing by the Guarantor of such Indebtedness
         is prohibited unless the amount of such extended, renewed or refinanced
         Indebtedness by the Guarantor is deducted from Indebtedness allowed
         under Section 9.1(d) above; and

                  (f) Indebtedness of the Borrower and certain of its
         Subsidiaries under the Revolving Credit Facility and the European
         Credit Facilities.

         SECTION 9.2. RESTRICTIONS ON LIENS. The Borrower will not, and will
cause its Subsidiaries not to, create or incur or suffer to be created or
incurred or to exist any lien, encumbrance, mortgage, pledge, charge,
restriction or other security interest of any kind upon any property or assets
of any character, whether now owned or hereafter acquired, or upon the income or
profits therefrom; or transfer any of such property or assets or the income or
profits therefrom for the purpose of subjecting the same to the payment of
Indebtedness or performance of any other obligation in priority to payment of

property or assets upon conditional sale or other title retention or purchase
money security agreement, device or arrangement; or suffer to exist for a period

                  (b) Liens securing Indebtedness permitted by Section 9.1(b)(i)

         and securing only the obligations with respect thereto);

                  (d) Liens to secure taxes, assessments and other government

                  (e) Deposits or pledges made in connection with, or to secure
         payment of, workmen's compensation, unemployment insurance, old age
         pensions or other social security obligations;

                  (f) Liens in respect of judgments or awards which have been in
         force for less than the applicable period for taking an appeal so long
         as execution is not levied thereunder or in respect of which the
         Borrower (or any Subsidiary) shall at the time in good faith be
         prosecuting an appeal or proceedings for review and in respect of which
         a stay of execution shall have been obtained pending such appeal or
         review and in respect of which the Borrower maintains adequate
         reserves;

                  (g) Liens of carriers, warehousemen, mechanics and
         materialmen, and other like liens, in existence less than 120 days from
         the date of creation thereof in respect of obligations not overdue,
         provided that such liens may continue to exist for a period of more
         than 120 days if the validity or amount thereof shall currently be
         contested by the Borrower (or any Subsidiary) in good faith by
         appropriate proceedings and if the Borrower shall have set aside on its
         books adequate reserves with respect thereto as required by GAAP and

         the Borrower interferes materially with the use of the property
         affected in the ordinary conduct of the business of the Borrower or any
         of its Subsidiaries, which defects do not individually or in the
         aggregate have a material adverse effect on the business of the
         Borrower or any Subsidiary individually or of the Borrower and its
         Subsidiaries on a consolidated basis.

                  The Borrower and the Guarantor covenant and agree that if
         either of them or any of their Subsidiaries shall create or assume any
         lien upon any of their respective properties or assets, whether now
         owned or hereafter acquired, other than Permitted Liens (unless prior
         written consent shall have been obtained from the Banks), the Borrower
         and the Guarantor will make or cause to be made effective provision
         whereby the Obligations and the Guaranteed Obligations will be secured
         by such lien equally and ratably with any and all other Indebtedness
         thereby secured so long as such other Indebtedness shall be so secured;
         provided, that the covenants of the Borrower and the Guarantor
         contained in this sentence shall only be in effect for so long as the
         Borrower or the Guarantor shall be similarly obligated under any other
         Indebtedness; provided, further, that an Event of Default shall occur
         for so long as such other Indebtedness becomes secured notwithstanding
         any actions taken by the Borrower or the Guarantor to ratably secure
         the Obligations and the Guaranteed Obligations hereunder.

         SECTION 9.3. RESTRICTIONS ON INVESTMENTS. Except to the extent provided
in Section 9.4, neither the Borrower nor any Subsidiary may make or permit to

         shall be the surviving entity with respect to any such transaction to
         which the Borrower is a party and the Guarantor shall be the survivor
         of any merger with any other Subsidiary or a Subsidiary shall be the
         surviving entity (and continue to be a Subsidiary) with respect to any
         such transactions to which one or more Subsidiaries is a party (and the
         conditions set forth below are satisfied), or purchase or otherwise
         acquire all or substantially all of the assets or stock of any class

         Subsidiaries of the Borrower which are wholly owned by the Borrower,
         (2) Regulatory Dispositions, (3) Strategic Dispositions, (4) Allied
         Waste Transactions, and (5) so long as no Default or Event of Default
         has occurred and is continuing, or would result therefrom, sales of
         assets in the ordinary course of business in any calendar year with an
         aggregate value not greater than $50,000,000), or sell or assign, with
         or without recourse, any receivables (except accounts receivable (and

         more than sixty (60) days past due sold or assigned in the ordinary
         course of collecting past due accounts, or pursuant to a Permitted

         Section 4068 of ERISA; or

                  (d) permit or take any action which would result in the

         limits, and policy terms, and otherwise describing the insurance
         obtained in accordance with the provisions of the Loan Documents and

         insurer).

                  SECTION 11.1.6. OPINION OF COUNSEL. The Banks shall have
         received a favorable legal opinion from outside counsel to the Borrower

         form and substance satisfactory to the Administrative Agent.

                  SECTION 11.1.7. SATISFACTORY FINANCIAL CONDITION. Other than
         as disclosed in the Disclosure Documents, no material adverse change,
         in the judgment of the Majority Banks, shall have occurred in the
         financial condition, results of operations, business, properties or
         prospects of the Borrower and its Subsidiaries, taken as a whole, since
         the Interim Balance Sheet Date.

                  SECTION 11.1.8. PAYMENT OF AMENDMENT FEES. For each Bank which
         executed and delivered its facsimile signature pages by 5:00 p.m. on

         amendment fee of 0.125% on each such Bank's Commitment to the
         Administrative Agent for the account of such Banks.

                  SECTION 11.1.9. AMENDMENTS TO EXISTING DEBT. The
         Administrative Agent shall have received evidence, in form and
         substance satisfactory to the Administrative Agent, that the Revolving
         Credit Facility is concurrently becoming effective in a form and
         substance satisfactory to the Administrative Agent, MGT and the Joint
         Lead Arrangers and Joint Book Managers, and no "Event of Default",
         "Default" (each as defined in such agreement) or prepayment event shall
         exist under such agreement and no liens shall be created under such
         agreement as a result of the transactions contemplated hereby.

         SECTION 12. CONDITIONS TO ALL LOANS. The obligations of the Banks to
make any Loan and the obligation of any Issuing Bank to issue, extend, or renew
any Letter of Credit at the time of and subsequent to the Effective Date is
subject to the following conditions precedent:

         SECTION 12.1. REPRESENTATIONS TRUE. Each of the representations and
warranties of the Borrower and the Guarantor (as applicable) contained in this
Agreement or in any document or instrument delivered pursuant to or in
connection with this Agreement shall be true as of the date as of which they
were made and shall also be true at and as of the time of the making of such
Loan or the issuance, extension, or renewal of any Letter of Credit, as
applicable, with the same effect as if made at and as of that time (except to
the extent of changes resulting from transactions contemplated or permitted by
this Agreement and changes occurring in the ordinary course of business which
singly or in the aggregate are not materially adverse to the business,




<PAGE>   68

assets or financial condition of the Borrower and its Subsidiaries as a whole,
and to the extent that such representations and warranties relate expressly and
solely to an earlier date).

         SECTION 12.2. PERFORMANCE; NO EVENT OF DEFAULT. The Borrower shall have
performed and complied with all terms and conditions herein required to be
performed or complied with by it prior to or at the time of the making of any
Loan the issuance, extension or renewal of any Letter of Credit, and at the time
of the making of any Loan or the issuance, renewal or extension of any Letter of
Credit, there shall exist no Default or Event of Default or condition which
would result in a Default or an Event of Default upon consummation of such Loan
or issuance, extension, or renewal of any Letter of Credit, as applicable. Each
request for a Loan, or for issuance, extension or renewal of a Letter of Credit
shall constitute certification by the Borrower that the conditions specified in
Sections 12.1 and 12.2 will be duly satisfied on the date of such Loan or Letter
of Credit issuance, extension or renewal.

         SECTION 12.3. NO LEGAL IMPEDIMENT. No change shall have occurred in any
law or regulations thereunder or interpretations thereof which in the reasonable
opinion of the Banks would make it illegal for the Banks to make Loans, for any
Issuing Bank to issue, extend or renew, or the Banks to participate in, Letters
of Credit hereunder.

         SECTION 12.4. GOVERNMENTAL REGULATION. The Banks shall have received
from the Borrower and its Subsidiaries such statements in substance and form
reasonably satisfactory to the Banks as they shall require for the purpose of
compliance with any applicable regulations of the Comptroller of the Currency or
the Board of Governors of the Federal Reserve System or the Office of the
Superintendent of Financial Institutions.

         SECTION 12.5. PROCEEDINGS AND DOCUMENTS. All proceedings in connection
with the transactions contemplated by this Agreement and all documents incident
thereto shall have been delivered to the Banks as of the date of the making of
any extension of credit in substance and in form satisfactory to the Banks,
including without limitation a Syndicated Loan Request in the form attached
hereto as Exhibit D or a Letter of Credit Request in the form of Exhibit E and
the Banks shall have received all information and such counterpart originals or
certified or other copies of such documents as the Banks may reasonably request.

         SECTION 13. EVENTS OF DEFAULT; ACCELERATION; TERMINATION OF COMMITMENT.

         SECTION 13.1. EVENTS OF DEFAULT AND ACCELERATION. If any of the
following events ("Events of Default" or, if the giving of notice or the lapse
of time or both is required, then, prior to such notice and/or lapse of time,
"Defaults") shall occur:

                  (a) if the Borrower shall fail to pay any principal of the
         Loans when the same shall become due and payable, whether at the stated
         date of maturity or any accelerated date of maturity or at any other
         date fixed for payment;

                  (b) if the Borrower shall fail to pay any interest or fees or
         other amounts owing hereunder (other than those specified in subsection
         (a) above) within five (5) Business Days after the same shall become
         due and payable whether at the Revolving



<PAGE>   69

         Credit Maturity Date, Term Loan Maturity Date or any accelerated date
         of maturity or at any other date fixed for payment;

                  (c) if the Borrower shall fail to comply with any of the
         covenants contained in Sections 8, 9 and 10 hereof;

                  (d) if the Borrower shall fail to perform any term, covenant
         or agreement contained herein or in any of the other Loan Documents
         (other than those specified in subsections (a), (b), and (c) above) and
         such failure shall not be remedied within 30 days after written notice
         of such failure shall have been given to the Borrower by the
         Administrative Agent or any of the Banks;

                  (e) if any representation or warranty contained in this
         Agreement or in any document or instrument delivered pursuant to or in
         connection with this Agreement shall prove to have been false in any
         material respect upon the date when made or repeated;

                  (f) if the Borrower or any of its Subsidiaries shall fail to
         pay when due, or within any applicable period of grace, any
         Indebtedness in an aggregate amount greater than $50,000,000, or fail
         to observe or perform any material term, covenant or agreement
         contained in any one or more agreements by which it is bound,
         evidencing or securing any Indebtedness in an aggregate amount greater
         than $50,000,000 for such period of time as would permit, 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 or terminate its commitment with
         respect thereto;

                  (g) if the Borrower, the Guarantor or any Material Subsidiary
         makes an assignment for the benefit of creditors, or admits in writing
         its inability to pay or generally fails to pay its debts as they mature
         or become due, or petitions or applies for the appointment of a trustee
         or other custodian, liquidator or receiver of the Borrower, the
         Guarantor or any Material Subsidiary, or of any substantial part of the
         assets of the Borrower, the Guarantor or any Material Subsidiary or
         commences any case or other proceeding relating to the Borrower, the
         Guarantor or any Material Subsidiary under any bankruptcy,
         reorganization, arrangement, insolvency, readjustment of debt,
         dissolution or liquidation or similar law of any jurisdiction, now or
         hereafter in effect, or takes any action to authorize or in furtherance
         of any of the foregoing, or if any such petition or application is
         filed or any such case or other proceeding is commenced against the
         Borrower, the Guarantor or any Material Subsidiary or the Borrower, the
         Guarantor or any Material Subsidiary indicates its approval thereof,
         consent thereto or acquiescence therein;

                  (h) if a decree or order is entered appointing any such
         trustee, custodian, liquidator or receiver or adjudicating the Borrower
         or the Guarantor or any Material Subsidiary bankrupt or insolvent, or
         approving a petition in any such case or other proceeding, or a decree
         or order for relief is entered in respect of the Borrower or the
         Guarantor or any Material Subsidiary in an involuntary case under
         federal bankruptcy laws of any jurisdiction as now or hereafter
         constituted, and such decree or order remains in effect for more than
         30 days, whether or not consecutive;


<PAGE>   70

                  (i) if there shall remain in force, undischarged, unsatisfied
         and unstayed, for more than thirty days, whether or not consecutive,
         any final judgment against the Borrower or any Subsidiary which, with
         other outstanding final judgments against the Borrower and its
         Subsidiaries exceeds in the aggregate $25,000,000 after taking into
         account any undisputed insurance coverage;

                  (j) if, with respect to any Guaranteed Pension Plan (or any
         corresponding plan described in any Applicable Canadian Pension
         Legislation), an ERISA Reportable Event or similar event under
         Applicable Canadian Pension Legislation shall have occurred and the
         Banks shall have determined in their reasonable discretion that such
         event reasonably could be expected to result in liability of the
         Borrower or any Subsidiary to the PBGC or similar Canadian authorities
         or the Plan in an aggregate amount exceeding $25,000,000 and such event
         in the circumstances occurring reasonably could constitute grounds for
         the partial or complete termination of such Plan by the PBGC or similar
         Canadian authorities or for the appointment by the appropriate United
         States District Court or Canadian Court of a trustee to administer such
         Plan; or a trustee shall have been appointed by the appropriate United
         States District Court or Canadian Court to administer such Plan; or the
         PBGC or similar Canadian authorities shall have instituted proceedings
         to terminate such Plan;

                  (k) if any of the Loan Documents shall be cancelled,
         terminated, revoked or rescinded otherwise than in accordance with the
         terms thereof or with the express prior written agreement, consent or
         approval of the Banks, or any action at law, suit or in equity or other
         legal proceeding to cancel, revoke or rescind any of the Loan Documents
         shall be commenced by or on behalf of the Borrower, the Guarantor, or
         any of their respective stockholders, or any court or any other
         governmental or regulatory authority or agency of competent
         jurisdiction 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; or

                  (l) if any person or group of persons (within the meaning of
         Section 13 or 14 of the Securities Exchange Act of 1934, as amended)
         shall have acquired beneficial ownership (within the meaning of Rule
         13d-3 promulgated by the Securities and Exchange Commission under said
         Act) of 25% or more of the outstanding shares of common voting stock of
         the Borrower; or during any period of twelve consecutive calendar
         months, individuals who were directors of the Borrower on the first day
         of such period shall cease to constitute a majority of the board of
         directors of the Borrower;

then, and in any such event, so long as the same may be continuing, the
Administrative Agent may, and upon the request of the Majority Banks shall, by
notice in writing to the Borrower, declare all amounts owing with respect to
this 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, notice of intent to
accelerate, notice of acceleration to the extent permitted by law or other
notice of any kind, all of which are hereby expressly waived by the Borrower;
provided that in the event of any Event of Default specified in Section 13.1(g)
or 13.1(h), all such amounts shall become immediately due and



<PAGE>   71

payable automatically and without any requirement of notice from the
Administrative Agent or any Bank. Upon demand by the Majority Banks after the
occurrence of any Event of Default, the Borrower shall immediately provide to
the Administrative Agent cash in an amount equal to the aggregate Maximum
Drawing Amount to be held by the Administrative Agent as collateral security for
the Reimbursement Obligations.

         SECTION 13.2. TERMINATION OF COMMITMENTS. If any Event of Default
pursuant to Sections 13.1(g) or 13.1(h) hereof shall occur, any unused
portion of the Total Commitment hereunder shall forthwith terminate and the
Banks and the Issuing Banks shall be relieved of all obligations to make Loans
or to issue, extend or renew Letters of Credit hereunder; or if any other Event
of Default shall occur, the Majority Banks may by notice to the Borrower
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 and the Issuing Banks shall be relieved of
all further obligations to make Loans or to issue, extend or renew Letters of
Credit hereunder. No termination of any portion of the Total Commitment
hereunder shall relieve the Borrower of any of its existing Obligations to the
Banks, the Issuing Banks or the Administrative Agent hereunder or elsewhere.

         SECTION 13.3. REMEDIES. In case any one or more of the Events of
Default shall have occurred and be continuing, and whether or not the Banks
shall have accelerated the maturity of the Loans and other Obligations pursuant
to Section 13.1, each Bank, upon notice to the other Banks, if owed any amount
with respect to the Loans or the Reimbursement Obligations, may 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 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, any recovery being subject to the terms
of Section 30 hereof. No remedy herein conferred upon any Bank or the
Administrative Agent or the holder of any Note 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 14. 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 Borrower and any securities or other
property of the Borrower in the possession of such Bank may be applied to or set
off against the payment of 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 Borrower to the Banks or the Administrative Agent.
Any amounts set off pursuant to this Section 14 shall be distributed ratably in
accordance with Section 30 among all of the Banks by the Bank setting off such
amounts. If any Bank fails to share such setoff ratably, the Administrative
Agent shall have the right to withhold such Bank's share of the Borrower's
payments until each of the Banks shall have, in the aggregate, received a pro
rata repayment.


<PAGE>   72

         SECTION 15. EXPENSES. Whether or not the transactions contemplated
herein shall be consummated, the Borrower hereby promises to reimburse the
Administrative Agent for all reasonable out-of-pocket fees and disbursements
(including all reasonable attorneys' fees) incurred or expended in connection
with the syndication, preparation, filing or recording, or interpretation of
this Agreement, the other Loan Documents, or any amendment, modification,
approval, consent or waiver hereof or thereof. The Borrower further promises to
reimburse the Administrative Agent and the Banks for all reasonable
out-of-pocket fees and disbursements (including all reasonable legal fees and
the allocable cost of in-house attorneys' fees) incurred or expended in
connection with the enforcement of any Obligations or the satisfaction of any
indebtedness of the Borrower hereunder or under any other Loan Document, or in
connection with any litigation, proceeding or dispute hereunder in any way
related to the credit hereunder. The Borrower also promises to pay the
Administrative Agent all reasonable out-of-pocket fees and disbursements,
incurred or expended in connection with the Competitive Bid Loan procedure under
Section 4 hereof.

         SECTION 16.  THE AGENTS.

         SECTION 16.1. APPOINTMENT, POWERS AND IMMUNITIES. Each Bank hereby
irrevocably appoints and authorizes BKB to act as Administrative Agent,
provided, however, the Administrative Agent is hereby authorized to serve only
as administrative and documentation agent for the Banks and to exercise such
powers as are reasonably incidental thereto and as are set forth in this
Agreement and the other Loan Documents. The Administrative 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
Agreement or the Loan Documents. Except as provided in this Agreement, and in
the other Loan Documents, the Administrative Agent shall take action or refrain
from acting only upon instructions of the Banks. It is agreed that the duties,
rights, privileges and immunities of the Issuing Banks, in their capacity as
issuers of Letters of Credit hereunder, shall be identical to the duties,
rights, privileges and immunities of the Administrative Agent as provided in
this Section 16. The Administrative Agent shall not have any duties or
responsibilities or any fiduciary relationship with any Bank except those
expressly set forth in this Agreement and the other Loan Documents. Neither the
Administrative Agent nor any of its affiliates shall be responsible to the Banks
for any recitals, statements, representations or warranties made by the Borrower
or any other Person whether contained herein or otherwise or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement, the other Loan Documents or any other document referred to or
provided for herein or therein or for any failure by the Borrower or any other
Person to perform its obligations hereunder or thereunder or in respect of the
Notes. The Administrative 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 Administrative Agent,
the Agents and any of their directors, officers, employees or agents shall not
be responsible for any action taken or omitted to be taken by it or them
hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct. The Administrative Agent in its separate
capacity as a Bank shall have the same rights and powers hereunder as any other
Bank. The Documentation Agent and the Syndication Agents shall not have any
right, power, obligation, liability, responsibility or



<PAGE>   73

duty under this Credit Agreement in such capacity, other than with respect to
the Documentation Agent, those applicable to all Banks as Banks.

         SECTION 16.2. ACTIONS BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be fully justified in failing or refusing to take any action under this
Agreement as reasonably deemed appropriate unless it shall first have received
the consent of the Majority Banks (or, when expressly required hereby, all 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 Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement or any of the Loan Documents in accordance with the instruction
of the Majority Banks (or, when expressly required hereby or thereby, all of the
Banks), and such instruction 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 16.3. INDEMNIFICATION. Without limiting the obligations of the
Borrower hereunder or under any other Loan Document, the Banks agree to
indemnify the Administrative Agent, its affiliates and its respective directors,
officers, agents and employees (to the extent not reimbursed by the Borrower)
ratably in accordance with their respective Commitment Percentages for any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may at any time be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of this Agreement or
any other Loan Document or any documents contemplated by or referred to herein
or therein or the transactions contemplated hereby or thereby or the enforcement
of any of the terms hereof or thereof or of any such other documents; provided,
that no Bank shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the Administrative Agent (or
any agent thereof) and provided further that no Bank shall be liable with
respect to acts of Section 20 Subsidiaries of other Banks, IT BEING THE INTENT
OF THE PARTIES HERETO THAT ALL SUCH INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR
THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

         SECTION 16.4. REIMBURSEMENT. Without limiting the provisions of
Sections 6.1(a), 6.12, and 14, the Administrative Agent shall not be obliged to
make available to any Person any sum which the Administrative Agent is expecting
to receive for the account of that Person until the Administrative Agent has
determined that it has received that sum. The Administrative Agent may, however,
disburse funds prior to determining that the sums which the Administrative Agent
expects to receive have been finally and unconditionally paid to the
Administrative Agent, if the Administrative Agent wishes to do so. If and to the
extent that the Administrative Agent does disburse funds and it later becomes
apparent that the Administrative Agent did not then receive a payment in an
amount equal to the sum paid out, then any Person to whom the Administrative
Agent made the funds available shall, on demand from the Administrative Agent,
refund to the Administrative Agent the sum paid to that Person. If, in the
opinion of the Administrative Agent, the distribution of any amount received by
it in such capacity hereunder or under the other 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



<PAGE>   74

a court of competent jurisdiction shall adjudge that any amount received and
distributed by the Administrative Agent is to be repaid, each Person to whom any
such distribution shall have been made shall either repay to the Administrative
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 16.5. DOCUMENTS. The Administrative Agent will forward to each
Bank, promptly after receipt thereof, a copy of each notice or other document
furnished to the Administrative Agent for such Bank hereunder; provided,
however, that, notwithstanding the foregoing, the Administrative 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 16.6. NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER BANKS.
Each Bank represents that it has, independently and without reliance on the
Administrative Agent, the Agents 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 Borrower and the Guarantor and the
decision to enter into this Agreement and the other Loan Documents and agrees
that it will, independently and without reliance upon the Administrative Agent,
the Agents 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 Agreement or any other Loan
Document. Except as herein expressly provided to the contrary, the
Administrative Agent shall not be required to keep informed as to the
performance or observance by the Borrower and the Guarantor of this 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 Administrative Agent hereunder, the Administrative
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 Administrative Agent or any of their affiliates. Each Bank
shall have access to all documents relating to the Administrative Agent's
performance of their duties hereunder at such Bank's request. Unless any Bank
shall promptly object to any action taken by the Administrative Agent hereunder
of which such Bank has actual knowledge (other than actions which require the
prior consent of such Bank in accordance with the terms hereof or to which the
provisions of Section 16.8 are applicable and other than actions which
constitute gross negligence or willful misconduct by the Administrative Agent),
such Bank shall be presumed to have approved the same.

         SECTION 16.7. RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative
Agent may resign at any time by giving 60 days' prior written notice thereof to
the Banks and the Borrower. Upon any such resignation, the Banks (other than the
resigning Administrative Agent) shall have the right to appoint a successor
Administrative Agent from among the Banks. If no successor to the Administrative
Agent shall have been so appointed by the Banks and shall have accepted such
appointment within 30 days after the retiring Administrative Agent's giving of
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent from among the remaining
Banks, which shall be a financial institution having a combined capital and
surplus in excess of $1,000,000,000. Upon the



<PAGE>   75

acceptance of any appointment as the Administrative Agent hereunder by a
successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder. After the
retiring Administrative Agent's resignation, the provisions of this 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 the Administrative Agent. Any
new Issuing Bank appointed pursuant to this Section 16.7 shall immediately issue
new Letters of Credit in place of Letters of Credit previously issued or, if
acceptable to the resigning Issuing Bank, issue letters of credit in favor of
the resigning Issuing Bank as security for the outstanding Letters of Credit and
shall in due course replace all Letters of Credit previously issued by the
resigning Issuing Bank.

         SECTION 16.8. ACTION BY THE BANKS, CONSENTS, AMENDMENTS, WAIVERS, ETC.
Any action to be taken (including the giving of notice) may be taken, any
consent or approval required or permitted by this Agreement or any other Loan
Document to be given by the Banks may be given, any term of this Agreement, any
other Loan Document or any other instrument, document or agreement related to
this Agreement or the other Loan Documents or mentioned therein may be amended,
and the performance or observance by the Borrower or any other Person of any of
the terms thereof and any Default or Event of Default (as defined in any of the
above-referenced documents or instruments) may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Majority Banks; provided, however, that no such consent
or amendment which affects the rights, duties or liabilities of the
Administrative Agent or any Issuing Bank shall be effective without the written
consent of the Administrative Agent or such Issuing Bank, as the case may be.
Notwithstanding the foregoing, no amendment, waiver or consent shall do any of
the following unless in writing and signed by ALL of the Banks (a) increase the
principal amount of the Total Commitment (or subject any Bank to any additional
obligations), (b) reduce the principal of or interest on the Notes (including,
without limitation, interest on overdue amounts) or any fees payable hereunder,
(c) postpone any date fixed for any payment in respect of principal or interest
(including, without limitation, interest on overdue amounts) on the Notes or any
fee hereunder (except pursuant to Section 2.10); (d) change the definition of
"Majority Banks" or 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
16.8; (f) change the Commitment Percentage of any Bank, except as permitted
under Section 21 and Section 2.10 hereof, (g) change the Total Commitment
Percentage of any Bank, or (h) release the Borrower or the Guarantor from its
obligations hereunder (except as expressly set forth herein).

         SECTION 17. INDEMNIFICATION. The Borrower agrees to indemnify and hold
harmless the Banks, the Agents, the Issuing Banks, the Joint Lead Arrangers and
Joint Book Managers and the Administrative Agent and their affiliates, as well
as the Banks' and the Administrative Agent's and their affiliates' shareholders,
directors, agents, officers, subsidiaries and affiliates, from and against all
damages, losses, settlement payments, obligations, liabilities, claims, suits,
penalties, assessments, citations, directives, demands, judgments, actions or
causes of action, whether statutorily created or under the common law, and
reasonable costs and expenses incurred, suffered, sustained or required to be
paid by an indemnified party by reason of or resulting from the transactions
contemplated hereby, except any of the foregoing which result from the gross
negligence or willful misconduct of any indemnified party. In any investigation,



<PAGE>   76

enforcement matter, proceeding or litigation, or the preparation therefor, the
Banks and the Administrative Agent shall be entitled to select their own counsel
and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly
the reasonable fees and expenses of such counsel (including the non-duplicative
allocated cost of internal counsel), and settlement costs. In the event of the
commencement of any such proceeding or litigation against the Banks or
Administrative Agent by third parties, the Borrower shall be entitled to
participate in such proceeding or litigation with counsel of their choice at
their expense, provided that such counsel shall be reasonably satisfactory to
the Banks or Administrative Agent. The covenants of this Section 17 shall
survive payment or satisfaction of payment of amounts owing with respect to any
Note or any other Loan Document and satisfaction of all the Obligations
hereunder, IT BEING THE INTENT OF THE PARTIES HERETO THAT ALL SUCH INDEMNIFIED
PARTIES SHALL BE INDEMNIFIED FOR THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

         SECTION 18. WITHHOLDING TAXES. The Borrower hereby agrees that:

                  (a) Any and all payments made by the Borrower hereunder shall
         be made free and clear of, and without deduction for, any and all
         present or future taxes, levies, fees, duties, imposts, deductions,
         charges or withholdings of any nature whatsoever, excluding, in the
         case of the Administrative Agent or the Banks or any holder of the
         Notes, (i) taxes imposed on, or measured by, its net income or profits,
         (ii) franchise taxes imposed on it, (iii) taxes imposed by any
         jurisdiction as a direct consequence of it, or any of its affiliates,
         having a present or former connection with such jurisdiction,
         including, without limitation, being organized, existing or qualified
         to do business, doing business or maintaining a permanent establishment
         or office in such jurisdiction, and (iv) taxes imposed by reason of its
         failure to comply with any applicable certification, identification,
         information, documentation or other reporting requirement (all such
         non-excluded taxes being hereinafter referred to as "Indemnifiable
         Taxes"). In the event that any withholding or deduction from any
         payment to be made by the Borrower hereunder is required in respect of
         any Indemnifiable Taxes pursuant to any applicable law, or governmental
         rule or regulation, then the Borrower will (i) direct to the relevant
         taxing authority the full amount required to be so withheld or
         deducted, (ii) forward to the Administrative Agent for delivery to the
         applicable Bank an official receipt or other documentation satisfactory
         to the Administrative Agent and the applicable Bank evidencing such
         payment to such taxing authority, and (iii) direct to the
         Administrative Agent for the account of the relevant Banks such
         additional amount or amounts as is necessary to ensure that the net
         amount actually received by each relevant Bank will equal the full
         amount such Bank would have received had no such withholding or
         deduction (including any Indemnifiable Taxes on such additional
         amounts) been required. Moreover, if any Indemnifiable Taxes are
         directly asserted against the Administrative Agent or any Bank with
         respect to any payment received by the Administrative Agent or such
         Bank by reason of the Borrower's failure to properly deduct and
         withhold such Indemnifiable Taxes from such payment, the Administrative
         Agent or such Bank may pay such Indemnifiable Taxes and the Borrower
         will promptly pay all such additional amounts (including any penalties,
         interest or reasonable expenses) as is necessary in order that the net
         amount received by such Person after the payment of



<PAGE>   77

         such Indemnifiable Taxes (including any Indemnifiable Taxes on such
         additional amount) shall equal the amount such Person would have
         received had not such Indemnifiable Taxes been asserted. Any such
         payment shall be made promptly after the receipt by the Borrower from
         the Administrative Agent or such Bank, as the case may be, of a written
         statement setting forth in reasonable detail the amount of the
         Indemnifiable Taxes and the basis of the claim.

                  (b) The Borrower shall pay any present or future stamp or
         documentary taxes or any other excise or any other similar levies which
         arise from any payment made hereunder or from the execution, delivery
         or registration of, or otherwise with respect to, this Agreement or any
         other Loan Document ("Other Taxes").

                  (c) The Borrower hereby indemnifies and holds harmless the
         Administrative Agent and each Bank for the full amount of Indemnifiable
         Taxes or Other Taxes (including, without limitation, any Indemnifiable
         Taxes or Other Taxes imposed on amounts payable under this Section 18)
         paid by the Administrative Agent or such Bank, as the case may be, and
         any liability (including penalties, interest and reasonable expenses)
         arising therefrom or with respect thereto, by reason of the Borrower's
         failure to properly deduct and withhold Indemnifiable Taxes pursuant to
         paragraph (a) above or to properly pay Other Taxes pursuant to
         paragraph (b) above. Any indemnification payment from the Borrower
         under the preceding sentence shall be made promptly after receipt by
         the Borrower from the Administrative Agent or Bank of a written
         statement setting forth in reasonable detail the amount of such
         Indemnifiable Taxes or such Other Taxes, as the case may be, and the
         basis of the claim.

                  (d) If the Borrower pays any amount under this Section 18 to
         the Administrative Agent or any Bank and such payee knowingly receives
         a refund of any taxes with respect to which such amount was paid, the
         Administrative Agent or such Bank, as the case may be, shall pay to the
         Borrower the amount of such refund promptly following the receipt
         thereof by such payee.

                  (e) In the event any taxing authority notifies the Borrower or
         the Guarantor that any of them has improperly failed to deduct or
         withhold any taxes (other than Indemnifiable Taxes) from a payment made
         hereunder to the Administrative Agent or any Bank, the Borrower shall
         timely and fully pay such taxes to such taxing authority.

                  (f) The Administrative Agent or the Banks shall, upon the
         request of the Borrower, take reasonable measures to avoid or mitigate
         the amount of Indemnifiable Taxes required to be deducted or withheld
         from any payment made hereunder if such measures can be taken without
         such Person in its sole judgment suffering any legal, regulatory or
         economic disadvantage.

                  (g) Without prejudice to the survival of any other agreement
         of the parties hereunder, the agreements and obligations of the
         Borrower contained in this Section 18 shall survive the payment in full
         of the Obligations.


<PAGE>   78

         SECTION 19.  TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.

         SECTION 19.1. SHARING OF INFORMATION WITH SECTION 20 SUBSIDIARY. The
Borrower acknowledges that from time to time financial advisory, investment
banking and other services may be offered or provided to the Borrower or one or
more of its Subsidiaries, in connection with this Agreement or otherwise, by a
Section 20 Subsidiary. The Borrower, for itself and each of its Subsidiaries,
hereby authorizes (a) such Section 20 Subsidiary to share with the
Administrative Agent and each Bank any information delivered to such Section 20
Subsidiary by the Borrower or any of its Subsidiaries, and (b) the
Administrative Agent and each Bank to share with such Section 20 Subsidiary any
information delivered to the Administrative Agent or such Bank by the Borrower
or any of its Subsidiaries pursuant to this Agreement, or in connection with the
decision of such Bank to enter into this Agreement; it being understood, in each
case, that any such Section 20 Subsidiary receiving such information shall be
bound by the confidentiality provisions of this Agreement. Such authorization
shall survive the payment and satisfaction in full of all of Obligations.

         SECTION 19.2. CONFIDENTIALITY. Each of the Banks and the Administrative
Agent agrees, on behalf of itself and each of its affiliates, directors,
officers, employees and representatives, to use reasonable precautions to keep
confidential, in accordance with their customary procedures for handling
confidential information of the same nature and in accordance with safe and
sound banking practices, any non-public information supplied to it by the
Borrower or any of its Subsidiaries pursuant to this Agreement that is
identified by such Person as being confidential at the time the same is
delivered to the Banks or the Administrative Agent, provided that nothing herein
shall limit the disclosure of any such information (a) after such information
shall have become public other than through a violation of this Section 19, (b)
to the extent required by statute, rule, regulation or judicial process, (c) to
counsel for any of the Banks or the Administrative Agent, (d) to bank examiners
or any other regulatory authority having jurisdiction over any Bank or the
Administrative Agent, or to auditors or accountants, (e) to the Administrative
Agent, any Bank or any Section 20 Subsidiary, (f) in connection with any
litigation to which any one or more of the Banks, the Administrative Agent or
any Section 20 Subsidiary is a party, or in connection with the enforcement of
rights or remedies hereunder or under any other Loan Document, (g) to a
Subsidiary or affiliate of such Bank as provided in Section 19.1 or (h) to any
assignee or participant (or prospective assignee or participant) so long as such
assignee or participant agrees to be bound by the provisions of Section 21.

         SECTION 19.3. PRIOR NOTIFICATION. Unless specifically prohibited by
applicable law or court order, each of the Banks and the Administrative Agent
shall, prior to disclosure thereof, notify the Borrower of any request for
disclosure of any such non-public information by any governmental agency or
representative thereof (other than any such request in connection with an
examination of the financial condition of such Bank by such governmental agency)
or pursuant to legal process.

         SECTION 19.4. OTHER. In no event shall any Bank or the Administrative
Agent be obligated or required to return any materials furnished to it or any
Section 20 Subsidiary by the Borrower or any of its Subsidiaries. The
obligations of each Bank under this Section 19 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 Borrower prior to the date
hereof and shall be binding upon



<PAGE>   79

any assignee of, or purchaser of any participation in, any interest in any of
the Loans or Reimbursement Obligations from any Bank.

         SECTION 20. 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 Borrower or the Guarantor pursuant hereto shall be deemed to have
been relied upon by the Banks, the Issuing Banks and the Administrative Agent,
notwithstanding any investigation heretofore or hereafter made by them, and
shall survive the making by the Banks of the Loans and the issuance, extension
or renewal of any Letters of Credit by any Issuing Bank, as herein contemplated,
and shall continue in full force and effect so long as any amount due under this
Agreement, any Obligation, any Letter of Credit or any Note remains outstanding
and unpaid or any Bank has any obligation to make any Loans or any Issuing Bank
has any obligation to issue, extend, or renew any Letters of Credit hereunder.
All statements contained in any certificate or other paper delivered by or on
behalf of the Borrower pursuant hereto or in connection with the transactions
contemplated hereby shall constitute representations and warranties by the
Borrower hereunder.

         SECTION 21. ASSIGNMENT AND PARTICIPATION. It is understood and agreed
that each Bank shall have the right to assign at any time all or a portion of
its Commitment Percentage and interests in the risk relating to the Loans,
outstanding Letters of Credit and its Commitment hereunder in an amount equal to
or greater than $5,000,000 (or, if a Bank's Commitment is less than $5,000,000,
in a minimum amount equal to such Bank's Commitment, provided that prior to any
Commitment reductions pursuant to Section 2.3, such Bank's Commitment was at
least $10,000,000) to additional banks or other financial institutions with the
prior written approval of the Administrative Agent and, so long as no Event of
Default has occurred and is continuing, the Borrower, which approvals shall not
be unreasonably withheld. Any Bank may at any time, and from time to time,
assign to any branch, lending office, or affiliate or such Bank all or any part
of its rights and obligations under the Loan Documents by notice to the
Administrative Agent and the Borrower. It is further agreed that each bank or
other financial institution which executes and delivers to the Administrative
Agent and the Borrower hereunder an Assignment and Acceptance substantially in
the form of Exhibit G hereto (an "Assignment and Acceptance") together with an
assignment fee in the amount of $3,500 payable by the assigning Bank to the
Administrative Agent, shall, on the date specified in such Assignment and
Acceptance, become a party to this Agreement and the other Loan Documents for
all purposes of this Agreement and the other Loan Documents, and its portion of
the Commitment, the Loans and Letters of Credit shall be as set forth in such
Assignment and Acceptance. The Bank assignor thereunder shall, to the extent
that rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement and the other Loan Documents. Upon the
execution and delivery of such Assignment and Acceptance, (a) the Borrower shall
issue to the assignee bank or other financial institution Notes in the amount of
such bank's or other financial institution's Commitment dated the date of the
assignment or such other date as may be specified by the Administrative Agent,
and otherwise completed in substantially the form of Exhibits A or B, and to the
extent any assigning Bank has retained a portion of its obligations hereunder, a
replacement Syndicated Note, to the assigning Bank reflecting its assignment;
(b) to the extent applicable, the Borrower shall issue a Competitive Bid Note in
substantially the form of Exhibit C (and a replacement



<PAGE>   80

Competitive Bid Note) or the Administrative Agent shall make appropriate entries
on the Competitive Bid Loan Accounts to reflect such assignment of Competitive
Bid Loan(s); (c) the Administrative Agent shall distribute to the Borrower, the
Banks and such bank or financial institution a revised Schedule 1 reflecting
such changes; and (d) this Agreement shall be deemed to be appropriately amended
to reflect (i) the status of the bank or financial institution as a party hereto
and (ii) the status and rights of the Banks hereunder.

         Each Bank shall also have the right to grant participations to one or
more banks or other financial institutions in its Commitment, the Loans and
outstanding Letters of Credit. The documents evidencing any such participation
shall limit such participating bank's or financial institution's voting rights
with respect to this Agreement to the matters set forth in Section 16.8 which
require the approval of all Banks.

         Notwithstanding the foregoing, no assignment or participation shall
operate to increase the Total Commitment hereunder or otherwise alter the
substantive terms of this Agreement, and no Bank which retains a Commitment
hereunder shall have a Commitment of less than $10,000,000, as such amount may
be reduced upon reductions in the Total Commitment pursuant to Section 2.3
hereof.

         Anything contained in this Section 21 to the contrary notwithstanding,
any Bank may at any time pledge all or any portion of its interest and rights
under this 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.

         The Borrower agrees that in addition to disclosures made in accordance
with standard and customary banking practices any Bank may disclose information
obtained by such Bank pursuant to this Agreement to assignees or participants
and potential assignees or participants hereunder; provided that such assignees
or participants or potential assignees or participants shall agree to be bound
by Section 19 hereof.

         SECTION 22. PARTIES IN INTEREST. All the terms of this Agreement and
the other Loan Documents shall be binding upon and inure to the benefit of and
be enforceable by the respective successors and assigns of the parties hereto
and thereto; provided, that the Borrower shall not assign or transfer its rights
or obligations hereunder or thereunder without the prior written consent of each
of the Banks.

         SECTION 23. NOTICES, ETC. Except as otherwise expressly provided in
this Agreement, all notices and other communications made or required to be
given pursuant to this Agreement or the other Loan Documents shall be in writing
and shall be delivered in hand, mailed by United States first class mail,
postage prepaid, or sent by telegraph, telex or facsimile and confirmed by
letter, addressed as follows:

                  (c) if to any Bank, at the last address provided to the
         Administrative Agent;

the Person giving the notice.

         Any such notice or demand shall be deemed to have been duly given or
made and to have become effective (a) if delivered by hand to a responsible
officer of the party to which it is directed, at the time of the receipt thereof
by such officer, (b) if sent by registered or certified first-class mail,
postage prepaid, five Business Days after the posting thereof, and (c) if sent
by telex, facsimile, or cable, at the time of the dispatch thereof, if in normal
business hours in the country of receipt, or otherwise at the opening of
business on the following Business Day.

         SECTION 24. MISCELLANEOUS. The rights and remedies herein expressed are
cumulative and not exclusive of any other rights which the Banks, the Issuing
Banks or the Administrative Agent would otherwise have. The captions in this
Agreement are for convenience of reference only and shall not define or limit
the provisions hereof. This Agreement and any amendment hereof may be executed
in several counterparts and by each party on a separate counterpart, each of
which when so executed and delivered shall be an original, but all of which
together shall constitute one instrument. In proving this Agreement it shall not
be necessary to produce or account for more than one such counterpart signed by
the party against whom enforcement is sought.

         SECTION 25. CONSENTS, ETC. Neither this Agreement nor any term hereof
may be changed, waived, discharged or terminated, except as provided in this
Section 25, subject to the provisions of Section 16.8. No waiver shall extend to
or affect any obligation not expressly waived or impair any right consequent
thereon. Except as otherwise expressly provided in this Agreement, any consent
or approval required or permitted by this Agreement to be given by the Banks may
be given, and any term of this Agreement or of any other instrument related
hereto or mentioned herein may be amended, and the performance or observance by
the Borrower of any terms of this Agreement 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 Borrower and the Majority Banks. To the
extent permitted by law, no course of dealing or delay or omission on the part
of any of the Banks, the Issuing Banks or the Administrative Agent in exercising
any right shall operate as a waiver thereof or otherwise be prejudicial thereto.
No notice to or demand upon the Borrower shall entitle the Borrower to other or
further notice or demand in similar or other circumstances.

         SECTION 26. WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY APPLICABLE
LAW, EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO A
JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR THE



<PAGE>   82

PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS. EXCEPT AS PROHIBITED BY LAW, THE
BORROWER AND THE GUARANTOR HEREBY WAIVE ANY RIGHT EITHER OF THEM MAY HAVE TO
CLAIM OR RECOVER IN ANY LITIGATION REFERRED TO IN THE PRECEDING SENTENCE ANY
SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN,
OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWER AND THE GUARANTOR EACH (A)
CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY BANK, ANY ISSUING
BANK, THE ADMINISTRATIVE AGENT OR ANY AGENT HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT SUCH BANK, SUCH ISSUING BANK, THE ADMINISTRATIVE AGENT OR SUCH
AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVERS AND (B) ACKNOWLEDGES THAT THE ADMINISTRATIVE AGENT, THE BANKS, AND THE
ISSUING BANKS HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS BECAUSE OF, AMONG OTHER THINGS, THE BORROWER'S AND THE GUARANTOR'S
WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

         SECTION 27. GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT
AND EACH OF THE OTHER LOAN DOCUMENTS ARE CONTRACTS UNDER THE LAWS OF THE STATE
OF NEW YORK AND SHALL, PURSUANT TO NEW YORK GENERAL OBLIGATIONS LAW SECTION
5-1401, BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF
NEW YORK. THE BORROWER AND THE GUARANTOR CONSENT AND AGREE THAT ANY SUIT FOR THE
ENFORCEMENT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS MAY BE BROUGHT
IN THE COURTS OF THE STATE OF NEW YORK OR ANY FEDERAL COURT SITTING THEREIN AND
CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURT AND SERVICE OF PROCESS
IN ANY SUCH SUIT BEING MADE UPON THE BORROWER IN ACCORDANCE WITH LAW AT THE
ADDRESS SPECIFIED IN SECTION 23. THE BORROWER AND THE GUARANTOR HEREBY WAIVE ANY
OBJECTION THAT THEY MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR
ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN INCONVENIENT COURT.

         SECTION 28. SEVERABILITY. The provisions of this Agreement are
severable and if any one clause or provision hereof shall be held invalid or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Agreement in
any jurisdiction.

         SECTION 29.  GUARANTY.

         SECTION 29.1. GUARANTY. For value received and hereby acknowledged and
as an inducement to the Banks and the Issuing Banks to make the Loans available
to the Borrower, and issue, extend or renew Letters of Credit for the account of
the Borrower, the Guarantor hereby unconditionally and irrevocably guarantees
(a) the full punctual payment when due, whether at stated maturity,



<PAGE>   83

by acceleration or otherwise, of all Obligations of the Borrower now or
hereafter existing whether for principal, interest, fees, expenses or otherwise,
and (b) the strict performance and observance by the Borrower of all agreements,
warranties and covenants applicable to the Borrower in the Loan Documents and
(c) the obligations of the Borrower under the Loan Documents (such Obligations
collectively being hereafter referred to as the "Guaranteed Obligations").

         SECTION 29.2. GUARANTY ABSOLUTE. The Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms
hereof, regardless of any law, regulation or order now or hereafter in effect in
any jurisdiction affecting any of such terms or the rights of any Bank, any
Issuing Bank or the Administrative Agent with respect thereto. The liability of
the Guarantor under the guaranty granted under this Agreement with regard to the
Guaranteed Obligations shall be absolute and unconditional irrespective of:

                  (a) any change in the time, manner or place of payment of, or
         in any other term of, all or any of its Guaranteed Obligations or any
         other amendment or waiver of or any consent to departure from this
         Agreement or any other Loan Document (with regard to such Guaranteed
         Obligations);

                  (b) any release or amendment or waiver of or consent to
         departure from any other guaranty for all or any of its Guaranteed
         Obligations;

                  (c) any change in ownership of the Borrower;

                  (d) any acceptance of any partial payment(s) from the Borrower
         or the Guarantor; or

                  (e) any other circumstance which might otherwise constitute a
         defense available to, or a discharge of, the Borrower in respect of its
         Obligations under any Loan Document.

         The guaranty under this Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any Guaranteed
Obligation is rescinded or must otherwise be returned by the Banks, the Issuing
Banks or the Administrative Agent upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, all as though such payment had not
been made.

         SECTION 29.3. EFFECTIVENESS; ENFORCEMENT. The guaranty under this
Agreement shall be effective and shall be deemed to be made with respect to each
Loan and each Letter of Credit as of the time it is made, issued or extended, or
becomes a Letter of Credit under this Agreement, as applicable. No invalidity,
irregularity or unenforceability by reason of any bankruptcy or similar law, or
any law or order of any government or agency thereof purporting to reduce, amend
or otherwise affect any liability of the Borrower, and no defect in or
insufficiency or want of powers of the Borrower or irregular or improperly
recorded exercise thereof, shall impair, affect, be a defense to or claim
against such guaranty. The guaranty under this Agreement is a continuing
guaranty and shall (a) survive any termination of this Agreement, and (b) remain
in full force and effect until payment in full of, and performance of, all
Guaranteed Obligations and

all other amounts payable under this Agreement. The guaranty under this
Agreement is made for the benefit of the Administrative Agent, the Issuing Banks
and the Banks and their successors and assigns, and may be enforced from time to
time as often as occasion therefor may arise and without requirement on the part
of the Administrative Agent, the Issuing Banks or the Banks first to exercise
any rights against the Borrower, or to resort to any other source or means of
obtaining payment of any of the said obligations or to elect any other remedy.

         SECTION 29.4. WAIVER. Except as otherwise specifically provided in any
of the Loan Documents, the Guarantor hereby waives promptness, diligence,
protest, notice of protest, all suretyship defenses, notice of acceptance and
any other notice with respect to any of its Guaranteed Obligations and the
guaranty under this Agreement and any requirement that the Banks, the Issuing
Banks or the Administrative Agent protect, secure, perfect any security interest
or lien or any property subject thereto or exhaust any right or take any action
against the Borrower or any other Person. The Guarantor also irrevocably waives,
to the fullest extent permitted by law, all defenses which at any time may be
available to it in respect of its Guaranteed Obligations by virtue of any
statute of limitations, valuation, stay, moratorium law or other similar law now
or hereafter in effect.

         SECTION 29.5. EXPENSES. The Guarantor hereby promises to reimburse (a)
the Administrative Agent for all reasonable out-of-pocket fees and disbursements
(including all reasonable attorneys' fees), incurred or expended in connection
with the preparation, filing or recording, or interpretation of the guaranty
under this Agreement, the other Loan Documents to which the Guarantor is a
party, or any amendment, modification, approval, consent or waiver hereof or
thereof, and (b) the Administrative Agent, the Issuing Banks and the Banks and
their respective affiliates for all reasonable out-of-pocket fees and
disbursements (including reasonable attorneys' fees), incurred or expended in
connection with the enforcement of its Guaranteed Obligations (whether or not
legal proceedings are instituted). The Guarantor will pay any taxes (including
any interest and penalties in respect thereof) other than the Banks' taxes based
on overall income or profits, payable on or with respect to the transactions
contemplated by the guaranty under this Agreement, the Guarantor hereby agreeing
jointly and severally to indemnify each Bank with respect thereto.

         SECTION 29.6. CONCERNING JOINT AND SEVERAL LIABILITY OF THE GUARANTOR.

                  (a) The Guarantor hereby irrevocably and unconditionally
         accepts, not merely as a surety but also as a co-debtor, joint and
         several liability with the Borrower, with respect to the payment and
         performance of all of its Guaranteed Obligations (including, without
         limitation, any Guaranteed Obligations arising under this Section 29),
         it being the intention of the parties hereto that all such Guaranteed
         Obligations shall be the joint and several Guaranteed Obligations of
         the Guarantor and the Borrower without preferences or distinction among
         them.

                  (b) If and to the extent that the Borrower shall fail to make
         any payment with respect to any of its Obligations as and when due or
         to perform any of its Guaranteed Obligations in accordance with the
         terms thereof, then in each such event the applicable Guarantor will
         make such payment with respect to, or perform, such Guaranteed
         Obligation.


<PAGE>   85

                  (c) The Guaranteed Obligations of the Guarantor under the
         provisions of this Section 29 constitute full recourse obligations of
         the Guarantor enforceable against the Guarantor to the full extent of
         its properties and assets, irrespective of the validity, regularity or
         enforceability of this Agreement or any other circumstance whatsoever.

                  (d) Except as otherwise expressly provided in this Agreement,
         the Guarantor hereby waives notice of acceptance of its joint and
         several liability, notice of any Loans made, or Letters of Credit
         issued under this Agreement, notice of any action at any time taken or
         omitted by the Administrative Agent, the Issuing Banks or the Banks
         under or in respect of any of the Guaranteed Obligations, and,
         generally, to the extent permitted by applicable law, all demands,
         notices and other formalities of every kind in connection with this
         Agreement. The Guarantor hereby assents to, and waives notice of, any
         extension or postponement of the time for the payment of any of the
         Guaranteed Obligations, the acceptance of any payment of any of the
         Guaranteed Obligations, the acceptance of any partial payment thereon,
         any waiver, consent or other action or acquiescence by the
         Administrative Agent, the Issuing Banks or the Banks at any time or
         times in respect of any Default or Event of Default by the Borrower or
         the Guarantor in the performance or satisfaction of any term, covenant,
         condition or provision of this Agreement or any other Loan Document,
         any and all other indulgences whatsoever by the Administrative Agent,
         the Issuing Banks or the Banks in respect of any of the Guaranteed
         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
         Guaranteed Obligations or the addition, substitution or release, in
         whole or in part, of the Borrower or the Guarantor. Without limiting
         the generality of the foregoing, the Guarantor assents to any other
         action or delay in acting or failure to act on the part of the Banks,
         the Issuing Banks or the Administrative Agent with respect to the
         failure by the Borrower or the Guarantor to comply with its respective
         Obligations or Guaranteed 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 29,
         afford grounds for terminating, discharging or relieving the Guarantor,
         in whole or in part, from any of the Guaranteed Obligations under this
         Section 29, it being the intention of the Guarantor that, so long as
         any of the Guaranteed Obligations hereunder remain unsatisfied, the
         Guaranteed Obligations of the Guarantor under this Section 29 shall not
         be discharged except by performance and then only to the extent of such
         performance. The Guaranteed Obligations of the Guarantor under this
         Section 29 shall not be diminished or rendered unenforceable by any
         winding up, reorganization, arrangement, liquidation, reconstruction or
         similar proceeding with respect to the Borrower or the Guarantor or the
         Banks, the Issuing Banks or the Administrative Agent. The joint and
         several liability of the Guarantor hereunder shall continue in full
         force and effect notwithstanding any absorption, merger, consolidation,
         amalgamation or any other change whatsoever in the name, membership,
         constitution or place of formation of the Borrower or the Guarantor,
         the Banks, the Issuing Banks or the Administrative Agent.

                  (e) The Guarantor shall be liable under this Section 29 only
         for the maximum amount of such liabilities that can be incurred under
         applicable law without rendering this Section 29 voidable under
         applicable law relating to fraudulent conveyance and fraudulent



<PAGE>   86

         transfer, and not for any greater amount. Accordingly, if any
         obligation under any provision under this Section 29 shall be declared
         to be invalid or unenforceable in any respect or to any extent, it is
         the stated intention and agreement of the Guarantor, the Administrative
         Agent, the Issuing Banks and the Banks that any balance of the
         obligation created by such provision and all other obligations of the
         Guarantor under this Section 29 to the Banks, the Issuing Banks or the
         Administrative Agent shall remain valid and enforceable, and that all
         sums not in excess of those permitted under applicable law shall remain
         fully collectible by the Banks, the Issuing Banks and the
         Administrative Agent from the Borrower or the Guarantor, as the case
         may be.

                  (f) The provisions of this Section 29 are made for the benefit
         of the Administrative Agent, the Issuing Banks and the Banks and their
         successors and assigns, and may be enforced in good faith by them from
         time to time against the Guarantor as often as occasion therefor may
         arise and without requirement on the part of the Administrative Agent,
         the Issuing Banks or the Banks first to marshal any of their claims or
         to exercise any of their rights against the Borrower or the Guarantor
         or to exhaust any remedies available to them against the Borrower or
         the Guarantor 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 29 shall remain in effect until
         all of the Guaranteed Obligations shall have been paid in full or
         otherwise fully satisfied and the Commitments have expired and all
         outstanding Letters of Credit have expired, matured or otherwise been
         terminated. If at any time, any payment, or any part thereof, made in
         respect of any of the Guaranteed Obligations, is rescinded or must
         otherwise be restored or returned by the Banks, the Issuing Banks or
         the Administrative Agent upon the insolvency, bankruptcy or
         reorganization of the Borrower or the Guarantor, or otherwise, the
         provisions of this Section 29 will forthwith be reinstated in effect,
         as though such payment had not been made.

         SECTION 29.7. WAIVER. Until the final payment and performance in full
of all of the Obligations, the Guarantor shall not exercise and the Guarantor
hereby waives any rights the Guarantor may have against the Borrower arising as
a result of payment by the Guarantor hereunder, by way of subrogation,
reimbursement, restitution, contribution or otherwise, and will not prove any
claim in competition with the Administrative Agent, the Issuing Banks or any
Bank in respect of any payment hereunder in any bankruptcy, insolvency or
reorganization case or proceedings of any nature; the Guarantor will not claim
any setoff, recoupment or counterclaim against the Borrower in respect of any
liability of the Borrower to the Guarantor; and the Guarantor waives any benefit
of and any right to participate in any collateral security which may be held by
the Administrative Agent, the Issuing Banks or any Bank.

         SECTION 29.8. SUBROGATION; SUBORDINATION. The payment of any amounts
due with respect to any indebtedness of the Borrower for money borrowed or
credit received now or hereafter owed to the Guarantor is hereby subordinated to
the prior payment in full of all of the Obligations. The Guarantor agrees that,
after the occurrence of any default in the payment or performance of any of the
Obligations, the Guarantor will not demand, sue for or otherwise attempt to
collect any such indebtedness of the Borrower to the Guarantor until all of the
Obligations shall have been paid in full. If, notwithstanding the foregoing
sentence, the Guarantor shall collect, enforce


<PAGE>   87

or receive any amounts in respect of such indebtedness while any Obligations are
still outstanding, such amounts shall be collected, enforced and received by the
Guarantor as trustee for the Banks, the Issuing Banks and the Administrative
Agent and be paid over to the Administrative Agent at Default, for the benefit
of the Banks, the Issuing Banks, and the Administrative Agent on account of the
Obligations without affecting in any manner the liability of the Guarantor under
the other provisions hereof.

         SECTION 30. PARI PASSU TREATMENT.

                  (a) Notwithstanding anything to the contrary set forth herein,
         each payment or prepayment of principal and interest received after the
         occurrence of an Event of Default hereunder shall be distributed pari
         passu among the Banks, in accordance with the aggregate outstanding
         principal amount of the Obligations owing to each Bank divided by the
         aggregate outstanding principal amount of all Obligations.

                  (b) Following the occurrence and during the continuance of any
         Event of Default, each Bank agrees that if it shall, through the
         exercise of a right of banker's lien, setoff or counterclaim against
         any Borrower (pursuant to Section 14 or otherwise), including a secured
         claim under Section 506 of the Bankruptcy Code or other security or
         interest arising from or in lieu of, such secured claim, received by
         such Bank under any applicable bankruptcy, insolvency or other similar
         law or otherwise, obtain payment (voluntary or involuntary) in respect
         of the Notes, Loans, Reimbursement Obligations and other Obligations
         held by it (other than pursuant to Section 6.4, Section 6.5 or Section
         6.7) as a result of which the unpaid principal portion of the Notes and
         the Obligations held by it shall be proportionately less than the
         unpaid principal portion of the Notes and Obligations held by any other
         Bank, it shall be deemed to have simultaneously purchased from such
         other Bank a participation in the Notes and Obligations held by such
         other Bank, so that the aggregate unpaid principal amount of the Notes,
         Obligations and participations in Notes and Obligations held by each
         Bank shall be in the same proportion to the aggregate unpaid principal
         amount of the Notes and Obligations then outstanding as the principal
         amount of the Notes and other Obligations held by it prior to such
         exercise of banker's lien, setoff or counterclaim was to the principal
         amount of all Notes and other Obligations outstanding prior to such
         exercise of banker's lien, setoff or counterclaim; provided, however,
         that if any such purchase or purchases or adjustments shall be made
         pursuant to this Section 30 and the payment giving rise thereto shall
         thereafter be recovered, such purchase or purchases or adjustments
         shall be rescinded to the extent of such recovery and the purchase
         price or prices or adjustments restored without interest. The Borrower
         expressly consents to the foregoing arrangements and agrees that any
         Person holding such a participation in the Notes and the Obligations
         deemed to have been so purchased may exercise any and all rights of
         banker's lien, setoff or counterclaim with respect to any and all
         moneys owing by the Borrower to such Person as fully as if such Person
         had made a Loan directly to the Borrower in the amount of such
         participation.

         SECTION 31. TRANSITIONAL ARRANGEMENTS. Upon the Effective Date (a) this
Agreement shall supersede the Prior Loan Agreement in its entirety, and (b) the
parties acknowledge and agree that the Pricing Table set forth herein shall be
applied retroactively to



<PAGE>   88

October 29, 1999 to the Loans and Letters of Credit outstanding under the Prior
Loan Agreement; and the Borrower hereby agrees to pay on December 15, 1999 (i)
any facility fees due under the Prior Loan Agreement, (ii) any incremental
amounts due as the result of such retroactive increase to the extent not paid on
or before the Effective Date, and (iii) any other amounts due under the Prior
Loan Agreement.

         SECTION 32. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

                    CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS
                    -----------------------------------------


         As independent public accountants, we hereby consent to the
incorporation by reference of our report on Waste Management, Inc.'s
consolidated financial statements for the year ended December 31, 1998 dated
February 25, 1999 (except with respect to the matters discussed in Notes 20 and
21 as to which the date is September 16, 1999) included in Waste Management,
Inc.'s Current Report on Form 8-K dated September 16, 1999 in this Registration
Statement on Form S-4 and related Prospectus of Waste Management, Inc. and to
all references to our Firm included in or incorporated by reference in this
Registration Statement.

         During the quarter ended September 30, 1999, the Company conducted a
review of its accounting records, systems, processes and controls. Based on that
review, the Company, after consultation with us, has concluded that its internal
controls for the preparation of interim financial information did not provide us
an adequate basis to complete reviews of the quarterly data for the quarters in
the nine-month period ended September 30, 1999. We have advised the Company that
our report on the December 31, 1999 financial statements will include the
following paragraph:

         "The selected quarterly financial data included in the Company's
         financial statements contain information that we did not audit, and
         accordingly, we do not express an opinion on that data. We attempted,
         but were unable, to review that quarterly data for the interim periods
         within 1999 in accordance with standards established by the American
         Institute of Certified Public Accountants because we believe that the
         Company's internal controls for the preparation of interim financial
         information did not provide an adequate basis to enable us to complete
         such a review."
