         3.1      OPERATION. On and after the Effective Date of this Agreement,
Contractor shall accept at any of the Disposal Sites all Waste Material
delivered to the Disposal Sites by Customer in accordance with the terms and
conditions of this Agreement.

         3.2      CONDITION PRECEDENT. The obligations of Contractor under this
Agreement are expressly subject to the prior issuance to Contractor, and the
continuing effectiveness, of all final, non-appealable licenses, permits and
approvals that are necessary to operate the Disposal Sites. Contractor
represents that it has obtained all licenses, permits and approvals which in its
good faith judgment are necessary for the operation of the Disposal Sites to be
in compliance with applicable laws and regulations.

         3.3      HOURS OF OPERATION. Each Disposal Site shall be open and
accept Waste Material for disposal during its respective posted hours of
operation. Contractor may, in its discretion, change the hours of operation at
any Disposal Site at any time; provided, however, that Customer's hauling trucks
shall have the same access hours for disposal at such Disposal Site as
Contractor's hauling trucks.

         3.4      HOLIDAYS. Each Disposal Site may, in the discretion of
Contractor, be closed on such legal holidays as determined from time to time by
Contractor.

         3.5      COMPLIANCE WITH APPLICABLE LAWS. Contractor shall comply with
all present and future federal, state, and local laws, regulations and
ordinances regulating the operation of landfills for the disposal of Waste
Material, and with all other rules, regulations, orders and amendments thereto
imposed by all federal and state regulatory agencies having jurisdiction over
the operation of the Disposal Sites.

         3.6      RIGHT TO REFUSE UNACCEPTABLE WASTE. Contractor shall not be
required to accept, and reserves the right to reject or revoke acceptance of,
any waste brought to a Disposal Site that Contractor, in its sole discretion,
considers to be an Unacceptable Waste or Suspicious Waste. Contractor will
require Customer to remove waste it has delivered which is subsequently
determined or suspected by Contractor to be Unacceptable Waste. If such
Unacceptable Waste is not removed from Contractor's possession by the Customer
within a reasonable time, not to

                                                                               3

exceed three (3) days from the receipt of such waste, Contractor will arrange
for lawful disposal of such waste. Customer will indemnify Contractor for any
costs or damages, including fines and penalties, resulting from delivery of
Unacceptable Waste to a Disposal Site, and will pay Contractor its reasonable
expenses and charges for handling, loading, preparing, transporting, storing and
caring for any such Unacceptable Waste disposed of by Contractor.

         3.7      REVOCATION OF ACCEPTANCE. Contractor may, at any time before
the condition of the waste has been materially changed, revoke its acceptance of
any waste discovered to be Unacceptable Waste. Revocation must occur within a
reasonable time after Contractor actually discovers or should have discovered
that the waste is Unacceptable Waste. In revoking its acceptance of any waste,
Contractor shall notify Customer of the manner in which the waste is
Unacceptable Waste.

         3.8      TITLE TO WASTE. Contractor is vested with title to all
Acceptable Waste accepted by Contractor at a Disposal Site. Any revenue or other
value received by Contractor as a result of reclamation, recycling or resource
recovery shall be solely for the account of Contractor.

         3.9      MINIMUM ANNUAL VOLUMES. Customer agrees to deliver to the
Disposal Sites an aggregate minimum annual disposal volume of [*] cubic yards of
Waste Material during each contract year of this Agreement (the "Minimum Annual
Volumes"), to be delivered to each of the Disposal Sites, on a site-specific
basis, in accordance with the volumes set forth on Exhibit "B" attached hereto
and incorporated herein by this reference for all purposes, which aggregate [*]
cubic yards of Waste Material (the "Site-Specific Disposal Site Waste"). The
remaining [*] cubic yards of Waste Material comprising the Minimum Annual
Volumes (the "Non-Specific Disposal Site Waste") shall be delivered by Customer
to Contractor to any of the Disposal Sites, in such amounts as Customer
determines, in its sole discretion, and shall be construed and counted as
Non-Specific Disposal Site Waste only after the Minimum Annual Volumes are
delivered at such Disposal Site. Notwithstanding anything contained in this
Agreement to the contrary, in the event less than [*] cubic yards of Waste
Material is delivered to the Disposal Sites under this Agreement during any one
(1) contract year, Contractor and Customer shall use good faith efforts to
renegotiate the Base Rates (as defined herein) contained in Exhibit "C" of this
Agreement within sixty (60) days after such Agreement anniversary date.
Notwithstanding anything contained herein to the contrary, in the event
Contractor and Customer, after using good faith efforts, are unable to
renegotiate such Base Rates, then Contractor may, at its sole and absolute
discretion, terminate this Agreement. Any Special Waste disposed of pursuant to
this Agreement shall not be included in the calculations for determination of
Minimum Annual Volumes.

         3.10     PRIOR AGREEMENT. This Agreement shall supersede that certain
Solid Waste Disposal Agreement by and between Customer and Contractor, dated
October 19, 1998.

                            SPECIAL WASTE MANAGEMENT

         4.1      REQUIREMENT FOR SPECIAL WASTE MANAGEMENT. Customer will
require all generators

                                                                               4
<Page>

of Special Waste collected by Customer and being disposed of at a Disposal Site
to participate in and implement a Special Waste program as described in this
Agreement.

         4.2      CONTRACTOR'S OBLIGATION REGARDING SPECIAL WASTE. Contractor is
not required to accept or manage any Special Waste unless it is specifically
identified in a written Special Waste agreement, approved in writing by
Contractor.

         4.3      DUTY OF CUSTOMER. Customer will require all waste generators
for which it has collection and disposal responsibility to execute a Special
Waste agreement prior to delivery of any Special Waste to a Disposal Site.
Customer will not deliver, arrange for the delivery of, or contract for the
delivery of any Special Waste to a Disposal Site without a fully executed
Special Waste agreement.

         4.4      SPECIAL WASTE AGREEMENT. The specific requirements of the
Special Waste agreement shall be as specified from time to time by Contractor
and may be altered by Contractor at any time as necessary to ensure the proper
management of Special Waste. At a minimum the Special Waste agreement shall
include:

                  (a)      A representative of the character and regulatory
         status of the waste to be executed by the generator;

                  (b)      A decision document to be executed by Contractor. A
         decision document shall at a minimum include the identification of the
         generator and the source and characterization of the waste;

                  (c)      A proposed management plan for the Special Waste,
         including any special handling requirements;

                  (d)      The approval of Contractor indicating acceptance for
         handling of the waste; and

                  (e)      The unit price for disposal associated with the
         management of the Special Waste.

         4.5      REPRESENTATIVE SAMPLE OF SPECIAL WASTE. Contractor may, in its
sole discretion, demand that a representative sample of any Special Waste
proposed for delivery to a Disposal Site be provided by the generator to
Contractor prior to the approval of a Special Waste agreement. Unless otherwise
agreed by Contractor, the cost for acquisition, delivery and analysis of a
representative sample shall be borne by the generator. If the generator refuses
to provide a representative sample, Contractor shall have no obligation to
accept the Special Waste or to execute a Special Waste agreement.

                                                                               5

                           COMPENSATION TO CONTRACTOR

         5.1      BASE RATE FOR DISPOSAL SITE. During the Initial Term of this
Agreement the base rates to be charged by Contractor for receiving and disposing
of Waste Material delivered by Customer to the Disposal Sites (the "Base Rates")
shall be as follows:

            SET FORTH IN EXHIBIT "C" ATTACHED HERETO AND INCORPORATED
                      HEREIN BY REFERENCE FOR ALL PURPOSES

         These rates shall include applicable state fees, including recycling
fees and post-closure fees, and local fees, including host fees, taxes and
royalties, and fees incurred under federal, state or local laws, rules or
ordinances in effect and/or implemented as of, but not subsequent to, the
Effective Date.

         5.2      BASE RATES ESCALATION AND ADJUSTMENT. At the end of each
contract year of this Agreement, the Contractor may increase the Base Rates as
follows:

         Rate Change = (CPI) x Base Rates for immediately preceding year

         For purposes of this Agreement, "CPI" shall mean the percentage change
for the preceding twelve (12) month period in the Consumer Price Index based on
the index entitled CPI-U "Dallas/Fort Worth Area" from the U.S. Department of
Labor, Bureau of Labor Statistics publication entitled "Consumer Price Indexes,
Pacific Cities and U.S. TASWA Average," 1977 - 100.

         Percentage changes in the index shall be calculated with the base year
of December 1977 until the Bureau of Labor Statistics ("BLS") publishes data on
a new base period. Calculations shall be made from data on the new base from
that time forward.

         If the CPI index specified above is discontinued, the parties hereto
shall agree by November 1 of the then applicable year to substitute another
equally authoritative measure of change in the purchasing power of the U.S.
dollar for CPIs as may be then available so as to carry out the intent of this
provision.

         If BLS designates an index with a new title or code number or table
number as being the continuation of the index cited above, the new index will be
used. If the specific index "Dallas/Fort Worth Area" is discontinued, then the
large metropolitan area closest to the "Dallas/Fort Worth Area" will be used. If
there is no area, but the "U.S. City Average" remains, this latter index will be
used. Otherwise, a substitute shall be agreed upon by the parties.

         Notwithstanding anything contained herein to the contrary, the Base
Rates set forth on Exhibit "C" shall only increase for any 12-month period to
the extent, and only in the amount, that the CPI for such year is in excess of
3.5%; however, in no event shall such increase of the Base Rates for such year
be in excess of 7% of the immediately prior year's Base Rate. For

                                                                               6
<Page>

example, if the CPI increase for a year is 4.0%, then the Base Rates for the
then applicable year shall increase by 0.5%. In no event shall the Base Rates
ever be decreased. The limitations on increases for the Base Rates as set forth
in this paragraph are hereinafter referred to as the "Base Rates Limitations".

         In addition to the foregoing, Contractor may increase Base Rates to
reflect the per cubic yard effect of any increase or increases in taxes, fees
and other governmental charges (including without limitation changes in TNRCC
fees) required by Federal, State or local law, regulation, rule ordinance or
permit condition that becomes effective or is implemented after the Effective
Date, and such increases shall be effective upon the date when such tax, or
other charge takes effect.

         5.3      PRICING FOR SPECIAL WASTE. Customer shall pay Contractor for
disposal of Special Waste the unit price established solely by Contractor. Unit
prices for Special Waste will vary depending on quantity and character of the
Special Waste, and will be priced by Contractor on a case-by-case basis
depending upon the nature and character of the Special Waste. Under no
circumstances shall the Base Rates be applicable to Special Waste.
Notwithstanding anything contained herein to the contrary, Special Waste unit
prices for those existing accounts of Customer and waste streams specifically
set forth in Exhibit "D" attached hereto and incorporated herein by this
reference for all purposes shall be as set forth therein, and subject to the
Base Rate escalation and adjustments set forth in Articles 5.1 and 5.2 of this
Agreement, but exclusive of, and not subject to, the Base Rates Limitations.

         5.4      BILLINGS.

                  (a) Contractor shall bill Customer monthly for the actual
         volume of Waste Material delivered by Customer to each Disposal Site
         during the previous month pursuant to this Agreement, multiplied by the
         then applicable Base Rate, or Base Rates, for that Disposal Site.
         Customer guarantees to Contractor to deliver the Minimum Annual Volumes
         of Waste Material to each Disposal Site as set forth on Exhibit "B".
         If, at the end of any contract year, Customer has not delivered to
         Contractor all volume of Site-Specific Disposal Site Waste to the
         respective Disposal Sites in accordance with Exhibit "B", then Customer
         shall be obligated to pay to Contractor, within thirty (30) days after
         the end of such contract year, a sum equal to the volume of cubic yards
         of the Site-Specific Disposal Site Waste required to be delivered, but
         not delivered, to each Disposal Site, multiplied by the applicable Base
         Rate. In addition, if, at the end of any contract year, Customer has
         not delivered to Contractor all required volume of cubic yards of the
         Non-Specific Disposal Site Waste, then, within thirty (30) days after
         the end of such contract year, Customer shall pay to Contractor a sum
         equal to the volume of cubic yards of the Non-Specific Disposal Site
         Waste not delivered to Contractor, multiplied by the average Base Rate
         for the applicable year for all Disposal Sites. It is the intent of the
         parties that, and Customer guaranties to Contractor the delivery to the
         Disposal Sites of, an aggregate minimum volume of [*] cubic yards of
         Waste Material per year, and in the event Customer fails to deliver
         such minimum volume to Disposal Sites, Customer shall

                                                                               7
<Page>

         pay Contractor for such undelivered cubic yardage as provided above in
         this Article 5.4.

                  (b)      Each invoice will detail the number of loads and
         amount and type of yards (loose or compacted) for the time period
         covered by the invoice. Customer will pay each invoice within thirty
         (30) days of the date of the invoice, without further notice by
         Contractor. A late charge of one percent (1%) per month will be imposed
         if the payment from Customer is past due.

         5.5      BOOKS AND RECORDS. Contractor will keep daily records of the
weight or volume of waste received and charges therefore, and Customer has the
right to inspect the same insofar as they pertain to the amount weight or volume
of waste received at each Disposal Site under this Agreement.

                                    ARTICLE 6
                                 INDEMNIFICATION

         Contractor agrees to indemnify, save harmless, and defend the Customer,
from and against any and all liabilities, claims, penalties, forfeitures, suits
and the costs and expenses incident thereto (including costs of defense,
settlement, and reasonable attorneys' fees), which it may hereafter incur,
become responsible for, or pay out as a result of death or bodily injuries to
any person, destruction or damage to any property, contamination of or adverse
effects on the environment, or any violation of governmental laws, regulations,
or orders caused by the Contractor's breach of any warranty, term or provision
of the Agreement, or by the negligent or willful acts or omissions of
Contractor, its employees, or its subcontractors in the performance of the
Agreement.

         Customer agrees to indemnify, save harmless, and defend the Contractor,
from and against any and all liabilities, claims, penalties, forfeitures, suits,
and the costs and expenses incident thereto (including costs of defense,
settlement, and reasonable attorneys' fees), which it may hereafter incur,
become responsible for, or payout as a result of death or bodily injuries to any
person, destruction or damage to any property, contamination of or adverse
effects on the environment, or any violation of governmental laws, regulations,
or orders caused by the Customer's breach of any warranty, term or provision of
the Agreement, or by the negligent or willful acts or omissions of Customer, its
employees, or its subcontractors in the performance of the Agreement.

                                  MISCELLANEOUS

         7.1      FORCE MAJEURE. The performance of this Agreement by either

judicial or governmental laws, regulations, requirements, orders, actions, or
inaction, including the revocation or suspension of or failure to obtain, for
reasons beyond Contractor's reasonable control, any licenses or permits required
for operation of a Disposal Site. In the event of disruption of services under
any such circumstances, Contractor will make every reasonable effort to reopen
the affected Disposal Site to accept waste as soon as practicable after the
cessation of the cause of suspension of services, and it will take all
reasonable steps to overcome the cause of cessation of service. Neither party
shall be liable to the other for the failure to perform its duties and
obligations under the Agreement or for any resultant damages, loss, or expenses,
if such failure was the result of any such Force Majeure. Further the affected
party shall use reasonable efforts to remove any Force Majeure condition.

         7.2      ENFORCEMENT. In the event that there is a dispute between the
parties, and either party brings an action to interpret this Agreement, or to

action is brought.

         7.3      RIGHT TO REQUIRE PERFORMANCE. The failure of either party at
any time to require performance by the other party of any provisions of this
Agreement will in no way affect the right of that party thereafter to enforce
the same. No waiver by either party of any breach of any of the provisions
hereof will be taken or held to be a waiver of any succeeding breach of such
provision or as a waiver of any other provision.

                                   EXHIBIT "A"

                                  SPECIAL WASTE

Special Waste means any discarded material from a nonresidential source meeting
any of the following descriptions for Type A or Type B Special Waste.

TYPE A SPECIAL WASTE. Any waste from a commercial or industrial activity meeting
any of the following descriptions.

1.       Containerized waste (e.g., a drum, portable tank, lugger box, roll-off
         box, pail, bulk tanker, etc.) listed in (b) through (h) below.

2.       Waste from a pollution control process (e.g., baghouse dust, treatment
         plant sludge, filter cake, sedimentation pond cleanout, etc.).

3.       Waste containing free liquids (free liquid wastes are those wastes
         which fail the paint filter test prescribed by the United States
         Environmental Protection Agency Method 9095).

4.       Residue and debris from the cleanup of a spill or a chemical substance
         or commercial product or a waste listed in (a) through (c) above or (e)
         through (h) below. This definition applies to spills of any size.

5.       Contaminated residuals from the cleanup of a facility generating,
         storing, treating, recycling, or disposing chemical substances,
         commercial products, or waste listed in (a) through (d) above or (0
         through (h) below.

6.       Any waste which is nonhazardous as a result of treatment pursuant to
         RCRA Subtitle C.

7.       Sludge waste.

8.       Waste from an industrial process.

TYPE B SPECIAL WASTE. Any waste from a commercial or industrial activity meeting
any of the descriptions which follow.

1.       Friable asbestos from building demolition or cleaning: wall board, wall
         or ceiling spray coverings, pipe insulation, etc. Nonfriable asbestos
         (e.g., asbestos containing floor tiles, brake pads, roofing products,
         etc.) is a Special Waste if it has been processed, handled, or used in
         such a way that asbestos fibers may be freely released. Asbestos
         bearing industrial process waste is a Type A Special Waste.

2.       Commercial products or chemicals which are off-specification, outdated,
         unused, or banned. Outdated or off-specification, uncontaminated food
         or beverage products in original consumer containers are not included
         in this category; however, containers which

                                                                               1
<Page>

         once held commercial products or chemicals are included if the
         container is empty. A container is empty when all wastes have been
         removed that can be removed using the practices commonly employed to
         remove materials from that type of container (e.g., pouring, pumping,
         or aspirating), an end has been removed (for containers in excess of 25
         gallons), and no more than one inch (2.54 centimeters) of residue
         remains on the bottom of the container or inner liner, or no more than
         3 percent by weight of the total capacity of the container remains in
         the container (for containers more or less than 110 gallons) or no more
         than 0.3 percent by weight of the total capacity of the container
         remains in the container (for containers greater than 110 gallons). A
         container which once held ACUTELY HAZARDOUS WASTES must be triple
         rinsed with an appropriate solvent or cleaned by an equivalent method.
         Containers which once held substances regulated under the Federal
         Insecticide, Fungicide, and Rodenticide Act must be empty according to
         label instructions or triple rinsed.

3.       Untreated biomedical waste. Any waste capable of inducing infection due
         to contamination with infectious agents from a biomedical source
         including but not limited to a hospital, medical clinic, nursing home,
         medical practitioner, mortuary, taxidermist, veterinarian, veterinary
         hospital, animal testing laboratory or medical testing laboratory. Any
         sharps from these sources must be rendered harmless or placed in needle
         puncture proof containers.

4.       Treated medical waste. Any waste from a biomedical source including but
         not limited to a hospital, medical clinic, nursing home, medical
         practitioner, mortuary, taxidermist, veterinarian, veterinary hospital,
         animal testing laboratory, or medical testing laboratory which has been
         autoclaved or otherwise heat treated or sterilized so that it is no
         longer capable of inducing infection. Any sharps from these sources
         must be rendered harmless or placed in needle puncture proof
         containers. Residue resulting from the incineration of medical waste is
         a Type A Special Waste.

5.       Residue/sludges from septic tanks, food service grease traps, or
         washwaters and wastewaters from commercial laundries, laundromats, and
         car washes. If these wastes are managed at a public or commercial
         wastewater treatment works, they are not a Special Waste.

6.       Chemical-containing equipment removed from service in which the
         chemical composition and concentration are known (e.g., oil filters,
         cathode ray tubes, lab equipment, acetylene tanks, fluorescent light
         tubes, etc.).

7.       Waste produced from the demolition or dismantling of industrial process
         equipment or facilities contaminated with chemicals from the industrial
         process. Chemicals or waste removed or drained from such equipment for
         facilities are Type A Special Wastes.

8.       Incinerator ash generated at a resource recovery facility that burns
         only nonhazardous household, commercial or industrial waste and
         qualifies for the hazardous waste exclusion in 40 CFR 261.4 (b). If the
         regulatory authority does not recognize the household hazardous waste
         exclusion, then the ash is a Type A Special Waste.

                                                                               2
