                                   ARTICLE II

                                   COMMITMENTS

         Section 2.01 Loans and Letters of Credit.

                  (a) Revolving Credit Loans. Each Lender severally agrees, on
the terms and conditions of this Agreement, to make loans to the Borrower during
the period from and including (i) the Closing Date or (ii) such later date that
such Lender becomes a party to this Agreement as provided in Section 13.06(b),
to and up to, but excluding, the Termination Date in an aggregate principal
amount at any one time outstanding up to, but not exceeding, the amount of such
Lender's Revolving Credit Commitment as then in effect; provided, however, that
the aggregate principal amount of all such Revolving Credit Loans by all Lenders
hereunder at any one time outstanding together with the LC Exposure, the Direct
Pay Letter of Credit Exposure and the outstanding Swing Line Loans shall not
exceed the Aggregate Revolving Credit Commitments. Subject to the terms of this
Agreement, during the period from the Closing Date to and up to, but excluding,
the Termination Date, the Borrower may borrow, repay and reborrow the amount
described in this Section 2.01(a).

                  (b) Direct Pay Letter of Credit. The Issuing Bank, subject to
the terms and conditions of the Existing Credit Agreement, issued the Direct Pay
Letter of Credit in a face amount not to exceed the Direct Pay Letter of Credit
Commitment for the account of the Borrower or Waste Corporation Texas as
described in the Reimbursement Agreement; provided, however, that the aggregate
principal amount of all such Revolving Credit Loans by all Lenders hereunder at
any one time outstanding together with the LC Exposure, the Direct Pay Letter of
Credit Exposure and the outstanding Swing Line Loans shall not exceed the
Aggregate Revolving Credit Commitments. In the event of any conflict between any
provision of the Reimbursement Agreement and this Agreement or the Existing
Credit Agreement, the Borrower, the Issuing Bank, the Administrative Agent and
the Lenders hereby agree that the provisions of the Reimbursement Agreement
shall govern. The Issuing Bank sent to the Borrower and each Lender, immediately
upon issuance of the Direct Pay Letter of Credit, a true and complete copy of
the Direct Pay Letter of Credit, and will send immediately upon issuance of any
amendment of the Direct Pay Letter of Credit, a true and correct copy of such
amendment. The Lenders participate in the Direct Pay Letter of Credit according
to their respective Percentage Shares pursuant to Section 2.10.

                  (c) Swing Line Loans.

                           (i) Solely for ease of administration of the
Revolving Credit Loans, the Swing Line Lender may, upon receipt of a notice
required under Section 2.02(c) on the proposed date of funding, but shall not be
required to, fund Base Rate Loans made in accordance with the provisions of this
Agreement, bearing interest as set forth in Section 3.02(a)(i). The Swing Line
Lender may, in its sole discretion and without conferring with the Lenders, make
Swing Line Loans to the Borrower by entry of credits to the Borrower's operating
account(s) with the Swing Line Lender to cover checks which the Borrower has
drawn or made against such account and shall notify the Administrative Agent of
any overdrafts being advanced as Swing Line Loans. The Borrower hereby requests
and authorizes the Swing Line Lender to make from



                                      -22-
<PAGE>

time to time such Swing Line Loans by means of appropriate entries of such
credits sufficient to cover checks then presented. The Borrower acknowledges and
agrees that the making of such Swing Line Loans shall be subject in all respects
to the provisions of this Agreement as if they were Swing Line Loans covered by
a request under Section 2.02(c), including, without limitation, the limitations
set forth in this Section 2.01 and the requirements that the applicable
provisions of Section 6.01 (in the case of Swing Line Loans made on the Closing
Date) and Section 6.02 be satisfied. All actions taken by the Swing Line Lender
pursuant to the provisions of this Section 2.01(c) shall be conclusive and
binding on the Borrower absent manifest error or such Swing Line Lender's gross
negligence or willful misconduct. The Swing Line Loans shall be evidenced by the
Swing Line Note; provided that the outstanding aggregate amount of Swing Line
Loans advanced by the Swing Line Lender hereunder shall not exceed the Swing
Line Commitment at any time. Each Lender shall remain severally and
unconditionally liable to fund its pro rata share (based upon each Lender's
Percentage Share) of such Swing Line Loans on each Settlement Date and, in the
event the Swing Line Lender chooses not to fund all Base Rate Loans requested on
any date, to fund its Percentage Share of the Base Rate Loans requested, subject
to satisfaction of the provisions hereof relating to the making of Base Rate
Loans. Prior to each Settlement, all payments or repayments of the principal of,
and interest on, Swing Line Loans shall be credited to the account of the Swing
Line Lender. The Borrower shall have the right, at its election, to prepay the
outstanding amount of the Swing Line Loans, as a whole or in part, at any time
without penalty or premium.

                           (ii) The Lenders shall effect Settlements on (A) the
Business Day immediately following any day which the Swing Line Lender gives
written notice to the Administrative Agent to effect a Settlement, (B) the
Business Day immediately following the Swing Line Lender's or the Administrative
Agent's becoming aware of the existence of any Default, (C) the Termination
Date, (D) any date on which the Borrower wishes to convert a Swing Line Loan
into a Revolving Credit Loan, and (E) in any event, on the first Business Day of
each calendar quarter for the immediately preceding calendar quarter (each such
date, a "Settlement Date"). One Business Day prior to each such Settlement Date,
the Administrative Agent shall give notice by facsimile or telecopier to the
Lenders of (1) the respective outstanding amount of Revolving Credit Loans made
by each Lender as at the close of the prior Business Day, and (2) the amount
that any Lender, as applicable (a "Settling Lender"), shall pay to effect a
settlement (a "Settlement Amount"). A statement of the Administrative Agent
submitted to the Lenders with respect to any amounts owing hereunder shall be
PRIMA FACIE evidence of the amount due and owing. Each Settling Lender shall,
not later than 11:00 a.m. (Central Time) on each Settlement Date, effect a wire
transfer of immediately available funds to the Administrative Agent, for the
benefit of the Swing Line Lender, at the Administrative Agent's Principal Office
in the amount of such Lender's Settlement Amount. All funds advanced by any
Lender as a Settling Lender pursuant to this Section 2.01(c) shall for all
purposes be treated as a Base Rate Loan by that Lender (in place of the Swing
Loan Lender) to the Borrower and all such funds so advanced shall be treated as
a payment in full of such amount by the Borrower under its Swing Line Note.

                           (iii) Subject to the Settling Lender's receipt of the
notice required pursuant to Section 2.01(c)(ii), the Administrative Agent may
(unless notified to the contrary by any Settling Lender by 11:00 a.m. (Central
Time) one Business Day prior to the Settlement Date) assume that each Settling
Lender has made available (or will make available by the time



                                      -23-
<PAGE>

specified in Section 2.01(c)(ii)) to the Administrative Agent its Settlement
Amount, and the Administrative Agent may (but shall not be required to), in
reliance upon such assumption, effect Settlements. If the Settlement Amount of
such Settling Lender is made available to the Administrative Agent on a date
after such Settlement Date, such Settling Lender shall pay the Administrative
Agent, for the benefit of the Swing Line Lender, on demand an amount equal to
the product of (A) the average, computed for the period referred to in clause
(C) 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 (B) such Settlement Amount times
(C) a fraction, the numerator of which is the number of days that elapse from
and including such Settlement Date to but not including the date on which such
Settlement Amount shall become immediately available to the Administrative
Agent, and the denominator of which is 360. Upon payment of such amount such
Settling Lender shall be deemed to have delivered its Settlement Amount on the
Settlement Date and shall become entitled to interest payable by the Borrower
with respect to such Settling Lender's Settlement Amount as if such share were
delivered on the Settlement Date. If such Settlement Amount is not in fact made
available to the Administrative Agent by such Settling Lender within three
Business Days of such Settlement Date, the Administrative Agent shall be
entitled to recover such amount from the Borrower, with any unpaid interest
thereon at the Base Rate.

                           (iv) After any Settlement Date, any payment by the
Borrower of Swing Line Loans hereunder shall be allocated pro rata among the
Lenders, in accordance with such Lender's Percentage Share.

                           (v) If, prior to the making of a Revolving Credit
Loan pursuant to clause (ii) of this Section 2.01(c), a Default has occurred and
is continuing, each Lender shall, on the date such Revolving Credit Loan was to
have been made, purchase an undivided participating interest in the outstanding
Swing Line Loans in an amount equal to its Percentage Share of such Swing Line
Loans. Each Lender will immediately transfer to the Administrative Agent, for
the benefit of the Swing Line Lender, in immediately available funds, the amount
of its participation and upon receipt thereof the Administrative Agent will
deliver to such Lender a Swing Line participation certificate dated the date of
receipt of such funds and in such amount.

                           (vi) Whenever, at any time after the Administrative
Agent has received from any Lender such Lender's participating interest in the
Swing Line Loans pursuant to clause (v) above, the Administrative Agent receives
any payment on account thereof, the Administrative Agent will distribute to such
Lender its participating interest in such amount (appropriately adjusted, in the
case of interest payments, to reflect the period of time during which such
Lender's participating interest was outstanding and funded) in like funds as
received; provided, however, that in the event that such payment received by the
Administrative Agent is required to be returned, such Lender will return to the
Administrative Agent any portion thereof previously distributed by the
Administrative Agent to it in like funds as such payment is required to be
returned by the Administrative Agent.

                           (vii) Each Lender's obligation to purchase
participating interests pursuant to clause (v) above shall be absolute and
unconditional and shall not be affected by any circumstance, including, without
limitation, (A) any set-off, counterclaim, recoupment, defense or other right
which such Lender may have against the Administrative Agent, the Borrower or



                                      -24-
<PAGE>

any other Person for any reason whatsoever; (B) the occurrence or continuance of
a Default; (C) any adverse change in the condition (financial or otherwise) of
the Borrower or any other Person; (D) any breach of this Agreement by the
Borrower or any other Lender or the Administrative Agent; or (E) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

                  (d) Letters of Credit. During the period from and including
the Closing Date to, but excluding, the date 30 days prior to the Termination
Date, the Issuing Bank, as issuing bank for the Lenders, agrees to extend credit
for the account of the Borrower or any Guarantor (other than the Parent) at any
time and from time to time by issuing, renewing, extending or reissuing Letters
of Credit; provided however, the LC Exposure at any one time outstanding shall
not exceed the lesser of (i) the LC Commitment or (ii) the Aggregate Revolving
Credit Commitments, as then in effect, minus the aggregate principal amount of
all Revolving Credit Loans, Swing Line Loans, the Direct Pay Letter of Credit
Exposure and the LC Exposure then outstanding. The Lenders shall participate in
such Letters of Credit according to their respective Percentage Shares. Each of
the Letters of Credit shall (i) be issued by the Issuing Bank, (ii) contain such
terms and provisions as are reasonably required by the Issuing Bank, (iii) be
for the account of the Borrower or any Guarantor (other than the Parent) and
(iv) expire not later than five Business Days prior to the Termination Date.

                  (e) Limitation on Types of Loans. Subject to the other terms
and provisions of this Agreement, at the option of the Borrower, the Loans may
be Base Rate Loans or LIBOR Loans; provided that, without the prior written
consent of the Majority Lenders, no more than 10 LIBOR Loans may be outstanding
at any time.

         Section 2.02 Borrowings, Continuations and Conversions, Letters of
Credit.

                  (a) Borrowings. The Borrower shall give the Administrative
Agent (which shall promptly notify the Lenders) advance notice as hereinafter
provided of each borrowing hereunder, which shall specify (i) the aggregate
amount of such borrowing, (ii) the Type and (iii) the date (which shall be a
Business Day) of the Loans to be borrowed, and (iv) (in the case of LIBOR Loans)
the duration of the Interest Period therefor.

                  (b) Minimum Amounts. All Base Rate Loan borrowings shall be in
amounts of at least $500,000 or the remaining balance of the Aggregate Revolving
Credit Commitments, if less, or any whole multiple of $100,000 in excess
thereof, and all LIBOR Loans shall be in amounts of at least $1,000,000 or any
whole multiple of $500,000 in excess thereof.

                  (c) Notices. All borrowings (except for borrowings
automatically funded under Section 2.10(d)), continuations and conversions shall
require advance written notice to the Administrative Agent (which shall promptly
notify the Lenders) in the form of Exhibit B (or telephonic notice promptly
confirmed by such a written notice), which in each case shall be irrevocable,
from the Borrower to be received by the Administrative Agent (i) not later than
11:00 a.m. (Central time) on the date of each Swing Line Loan and (ii) with
respect to all Loans other than Swing Line Loans, not later than 11:00 a.m.
(Central time) at least one Business Day prior to the date of each Base Rate
Loan borrowing and three Business Days prior to the date of each LIBOR Loan
borrowing, continuation or conversion. Without in any way limiting the



                                      -25-
<PAGE>

Borrower's obligation to confirm in writing any telephonic notice, the
Administrative Agent may act without liability upon the basis of telephonic
notice believed by the Administrative Agent in good faith to be from the
Borrower prior to receipt of written confirmation. In each such case, the
Borrower hereby waives the right to dispute the Administrative Agent's record of
the terms of such telephonic notice except in the case of gross negligence or
willful misconduct by the Administrative Agent.

                  (d) Continuation Options. Subject to the provisions made in
this Section 2.02(d), the Borrower may elect to continue all or any part of any
LIBOR Loan beyond the expiration of the then current Interest Period relating
thereto by giving advance notice as provided in Section 2.02(c) to the
Administrative Agent (which shall promptly notify the Lenders) of such election,
specifying the amount of such Loan to be continued and the Interest Period
therefor. In the absence of such a timely and proper election, the Borrower
shall be deemed to have elected to convert such LIBOR Loan to a Base Rate Loan
pursuant to Section 2.02(e). All or any part of any LIBOR Loan may be continued
as provided herein, provided that (i) any continuation of any such Loan shall be
(as to each Loan as continued for an applicable Interest Period) in amounts of
at least $1,000,000 or any whole multiple of $500,000 in excess thereof and (ii)
no Default shall have occurred and be continuing. If a Default shall have
occurred and be continuing, each LIBOR Loan shall be converted to a Base Rate
Loan on the last day of the Interest Period applicable thereto.

                  (e) Conversion Options. The Borrower may elect to convert all
or any part of any LIBOR Loan on the last day of the then current Interest
Period relating thereto to a Base Rate Loan by giving advance notice to the
Administrative Agent (which shall promptly notify the Lenders) of such election.
Subject to the provisions made in this Section 2.02(e), the Borrower may elect
to convert all or any part of any Base Rate Loan at any time and from time to
time to a LIBOR Loan by giving advance notice as provided in Section 2.02(c) to
the Administrative Agent (which shall promptly notify the Lenders) of such
election. All or any part of any outstanding Loan may be converted as provided
herein, provided that (i) any conversion of all or any part of any Base Rate
Loan into a LIBOR Loan shall be (as to each such Loan into which there is a
conversion for an applicable Interest Period) in amounts of at least $1,000,000
or any whole multiple of $500,000 in excess thereof and (ii) no Default shall
have occurred and be continuing. If a Default shall have occurred and be
continuing, no Base Rate Loan may be converted into a LIBOR Loan.

                  (f) Advances. Not later than 11:00 a.m. (Central time) on the
date specified for each borrowing hereunder, each Lender shall make available
the amount of the Loan to be made by it on such date to the Administrative
Agent, to an account which the Administrative Agent shall specify, in
immediately available funds, for the account of the Borrower. The amounts so
received by the Administrative Agent shall, subject to the terms and conditions
of this Agreement, be made available to the Borrower by depositing the same, in
immediately available funds, in an account of the Borrower, designated by the
Borrower and maintained at the Principal Office.

                  (g) Letters of Credit. The Borrower shall give the Issuing
Bank (which shall promptly notify the Lenders of such request and their
Percentage Share of such Letter of Credit) advance notice to be received by the
Issuing Bank not later than 11:00 a.m. (Central time) not



                                      -26-
<PAGE>

less than three Business Days prior thereto of each request for the issuance,
and at least the earlier of (A) 30 Business Days prior to the date of the
renewal or extension, of a Letter of Credit hereunder or (B) 30 calendar days
prior to the last date upon which the Issuing Bank is required to give notice of
cancellation or non-renewal of such Letter of Credit thereunder, which request
shall specify (i) the amount of such Letter of Credit, (ii) the date (which
shall be a Business Day) such Letter of Credit is to be issued, renewed or
extended, (iii) the duration thereof, (iv) the name and address of the
beneficiary thereof and (v) such other information as the Administrative Agent
may reasonably request, all of which shall be reasonably satisfactory to the
Administrative Agent. Subject to the terms and conditions of this Agreement, on
the date specified for the issuance, renewal or extension of a Letter of Credit,
the Administrative Agent shall issue, renew or extend such Letter of Credit to
the beneficiary thereof.

         In conjunction with the issuance of each Letter of Credit, the Borrower
shall execute a Letter of Credit Agreement. In the event of any conflict between
any provision of a Letter of Credit Agreement and this Agreement, the Borrower,
the Issuing Bank, the Administrative Agent and the Lenders hereby agree that the
provisions of this Agreement shall govern.

         The Issuing Bank will send to the Borrower and each Lender, immediately
upon issuance of any Letter of Credit, or an amendment thereto, a true and
complete copy of such Letter of Credit, or such amendment thereto.

         Section 2.03 Changes of Aggregate Revolving Credit Commitments.

                  (a) The Aggregate Revolving Credit Commitments shall be
automatically adjusted as a result of any reductions pursuant to Section 2.03(b)
or 2.08.

                  (b) The Borrower shall have the right to terminate or to
reduce the amount of the Aggregate Revolving Credit Commitments at any time, or
from time to time, upon not less than three Business Days' prior notice to the
Administrative Agent (which shall promptly notify the Lenders) of each such
termination or reduction, which notice shall specify the effective date thereof
and the amount of any such reduction (which shall not be less than $1,000,000 or
any whole multiple of $1,000,000 in excess thereof) and shall be irrevocable and
effective only upon receipt by the Administrative Agent.

                  (c) The Aggregate Revolving Credit Commitments once terminated
or reduced may not be reinstated.

         Section 2.04 Increase in Aggregate Revolving Credit Commitments.

                  (a) So long as (i) no Default has occurred and is continuing,
and (ii) the Borrower has not terminated or reduced in part any unused portion
of the Aggregate Revolving Credit Commitments at any time pursuant to Section
2.03, the Borrower may (1) at any time during the period beginning on the
Closing Date through the date syndication efforts of the Loans have been
completed, by notice to the Administrative Agent, request an increase in the
amount of the Aggregate Revolving Credit Commitments within the limitations
hereafter described and (2) at any time during the period beginning six months
after the Closing Date through and including the Termination Date, by notice to
the Administrative Agent, request a one-time increase in the amount of the
Aggregate Revolving Credit Commitments within the



                                      -27-
<PAGE>

limitations hereafter described, which notices shall set forth the amount of
such increase. In accordance with Section 2.04(d), the amount of the Aggregate
Revolving Credit Commitments may be so increased either by having one or more
New Lenders that have been approved by the Borrower become Lenders and/or by
having any one or more of the then existing Lenders (at their respective
election in their sole discretion) increase the amount of their Revolving Credit
Commitments ("Increasing Lenders"), provided that (i) the Revolving Credit
Commitment of any New Lender shall not be less than $5,000,000 and the sum of
the Revolving Credit Commitments of the New Lenders and the increases in the
Revolving Credit Commitments of the Increasing Lenders shall be in an aggregate
amount of not less than $5,000,000 (and, if in excess thereof, in integral
multiples of $1,000,000); (ii) the aggregate amount of all the increases in the
Revolving Credit Commitments pursuant to this Section 2.04 shall not exceed
Twenty-Five Million Dollars ($25,000,000); (iii) the Borrower, each New Lender
and/or each Increasing Lender shall have executed and delivered to the
Administrative Agent a commitment and acceptance (the "Commitment and
Acceptance") substantially in the form of Exhibit G hereto, and the
Administrative Agent shall have accepted and executed the same, (iv) the
Borrower shall have executed and delivered to the Administrative Agent a
Revolving Credit Note or Revolving Credit Notes payable to the order of each New
Lender and/or each Increasing Lender, each such Revolving Credit Note to be in
the amount of such New Lender's Revolving Credit Commitment or such Increasing
Lender's Revolving Credit Commitment (as applicable); (v) if requested by the
Administrative Agent, the Borrower shall have delivered to the Administrative
Agent opinions of counsel (substantially similar to the forms of opinions
provided for in Section 6.01(f), modified to apply to the increase in the
Revolving Credit Commitments and each new Revolving Credit Note and Commitment
and Acceptance executed and delivered in connection therewith); (vi) the
Guarantors shall have consented in writing to the new Revolving Credit
Commitments or increases in Revolving Credit Commitments (as applicable) and
shall have agreed that their Guaranty Agreement continues in full force and
effect, and (vii) the Borrower, each New Lender and/or each Increasing Lender
shall otherwise have executed and delivered such other instruments and documents
as the Administrative Agent shall have reasonably requested in connection with
such new Revolving Credit Commitment or increase in the Revolving Credit
Commitment (as applicable). The form and substance of the documents required
under clauses (iii) through (vii) above shall be reasonably acceptable to the
Administrative Agent. The Administrative Agent shall provide written notice to
all of the Lenders hereunder of the admission of any New Lender or the increase
in the Revolving Credit Commitment of any Increasing Lender hereunder and shall
furnish to each of the Lenders copies of the documents required under clause
(iii), (v), (vi) and (vii) above.

                  (b) Upon the effective date of any increase in the Aggregate
Revolving Credit Commitments pursuant to the provisions hereof (such date
hereinafter referred to as the "Increase Date"), which Increase Date shall be
mutually agreed upon by the Borrower, each New Lender, each Increasing Lender
and the Administrative Agent, each New Lender and/or Increasing Lender shall
make a payment to the Administrative Agent in an amount sufficient, upon the
application of such payments by all New Lenders and Increasing Lenders to the
reduction of the outstanding Revolving Credit Loans held by the Lenders
(including the Increasing Lenders) to cause the principal amount outstanding
under the Revolving Credit Loans made by each Lender to be equal to each
Lender's Percentage Share of the Aggregate Revolving Credit Commitments as so
increased. The Borrower hereby irrevocably authorizes each New Lender and/or
each Increasing Lender to fund to the Administrative Agent the payment required
to be made pursuant



                                      -28-
<PAGE>

to the immediately preceding sentence for application to the reduction of the
outstanding Revolving Credit Loans held by the other Lenders, and each such
payment shall constitute a Revolving Credit Loan hereunder. If, as a result of
the repayment of the Revolving Credit Loans provided for in this Section
2.04(b), any payment of a LIBOR Loan occurs on a day which is not the last day
of the applicable Interest Period, the Borrower will pay to the Administrative
Agent for the benefit of any of the Lenders (including any Increasing Lender to
the extent of LIBOR Loans held by such Increasing Lender prior to such Increase
Date) holding a LIBOR Loan any loss or cost incurred by such Lender resulting
therefrom in accordance with Section 5.05. Upon the Increase Date, all Revolving
Credit Loans outstanding hereunder (including any Revolving Credit Loans made by
the New Lenders and/or Increasing Lenders on the Increase Date) shall be Base
Rate Loans, subject to the Borrower's right to convert the same to LIBOR Loans
on or after such date in accordance with the provisions of Section 2.02.

                  (c) Upon the Increase Date and the making of the Revolving
Credit Loans by the New Lenders and/or Increasing Lenders in accordance with the
provisions of Section 2.04(b), each New Lender and/or each Increasing Lender
shall also be deemed to have irrevocably and unconditionally purchased and
received without recourse or warranty, from the Lenders immediately prior to the
Increase Date, an undivided interest and participation in any Letter of Credit
and Swing Line Loan, as applicable, then outstanding, ratably, such that each
Lender (including each New Lender) holds a participation interest in each such
Letter of Credit and Swing Line Loan, as applicable, in proportion to such
Lender's Percentage Share.

                  (d) Upon the notice by the Borrower to the Administrative
Agent pursuant to Section 2.04(a) hereof, each of the then existing Lenders
shall have the right (at such Lender's election) to increase its Revolving
Credit Commitment by an amount equal to such Lender's Percentage Share of the
proposed increase in the Aggregate Revolving Credit Commitments. If less than
all of the proposed increase in Aggregate Revolving Credit Commitments is
elected by the existing Lenders, then any of the then existing Lenders shall
have the right to increase its Revolving Credit Commitment in an amount greater
than such Lender's Percentage Share of the proposed increase in the Aggregate
Revolving Credit Commitments with the Administrative Agent's approval. If the
entire amount of the proposed increase in Aggregate Revolving Credit Commitments
is still not obtained, the Borrower may with the Administrative Agent's
cooperation add New Lenders, such New Lenders to be reasonably acceptable to the
Administrative Agent, with new Revolving Credit Commitments which when added to
the increase in Revolving Credit Commitments of the Increasing Lenders, shall
equal the requested increase in the Aggregate Revolving Credit Commitments. In
the event the sum of each New Lender's Revolving Credit Commitment and the
increase in each Increasing Lender's Revolving Credit Commitment is less than
the requested increase in the Aggregate Revolving Credit Commitments, the
Borrower may elect to accept the increase in the Aggregate Revolving Credit
Commitments to be equal to such lesser amount. Notwithstanding anything to the
contrary, Administrative Agent shall not be liable for any failure to obtain
Increasing Lenders or New Lenders hereunder or any failure to increase the
Aggregate Revolving Credit Commitments by the amount so requested by the
Borrower pursuant to Section 2.04(a).

                  (e) Nothing contained herein shall constitute, or otherwise be
deemed to be a commitment or agreement on the part of any Lender to increase its
Revolving Credit Commitment hereunder at any time. No Lender (except only for
itself) shall have the right to



                                      -29-
<PAGE>

decline Borrower's request pursuant to Section 2.04(a) for an increase in the
Aggregate Revolving Credit Commitments.

         Section 2.05 Fees.

                  (a) Commitment Fee. The Borrower shall pay to the
Administrative Agent for the account of each Lender a commitment fee on the
daily average unused amount of the Aggregate Revolving Credit Commitments for
the period from and including the Closing Date up to, but excluding, the earlier
of the date the Aggregate Revolving Credit Commitments are terminated or the
Termination Date at a rate per annum equal to the applicable per annum
percentage set forth at the appropriate intersection in the table shown below,
based on the Leverage Ratio on the most recent Determination Date:

<Table>
<Caption>
                   LEVERAGE RATIO                                                   COMMITMENT FEE PERCENTAGE
----------------------------------------------------------                          -------------------------
<S>                                                                                 <C>
Greater than or equal to 3.00:1.00                                                             0.500%
Less than 3.00:1.00 but greater than or equal to 1.50:1.00                                     0.375%
Less than 1.50:1.00                                                                            0.300%
</Table>

The commitment fee percentage shall be established as of each Determination Date
beginning with the fiscal quarter ending June 30, 2004. Any change in the
commitment fee percentage following each Determination Date shall be determined
based upon the information and computations set forth in the financial
statements and Compliance Certificate furnished to the Administrative Agent
pursuant to Section 8.01, subject to review and approval of such computations by
the Administrative Agent. Each change in the commitment fee percentage shall be
effective as of the first day of the calendar month following each Determination
Date and shall remain in effect until the date that is the first day of the
calendar month following the next Determination Date for which a change in the
commitment fee percentage occurs; provided, however; if the Borrower shall fail
to deliver any required financial statements or Compliance Certificate within
the time period required by Section 8.01, the commitment fee percentage shall be
the highest percentage amount set forth in the above table for the period
beginning on the relevant Determination Date and ending on the date that the
appropriate financial statements and Compliance Certificate are so delivered.
Notwithstanding the foregoing, during the period beginning on the Closing Date
and ending on June 30, 2004, the commitment fee percentage shall be 0.375%.
Accrued commitment fees shall be payable quarterly in arrears on each Quarterly
Date and on the earlier of the date the Aggregate Revolving Credit Commitments
are terminated or the Termination Date. For purposes of computing the commitment
fees payable hereunder, outstanding Swing Line Loans shall be disregarded.

                  (b) Letter of Credit and Direct Pay Letter of Credit Fees.

                           (i) The Borrower agrees to pay the Administrative
Agent, for the account of each Lender, commissions for issuing the Letters of
Credit on the daily average outstanding of the maximum liability of the Issuing
Bank existing from time to time under such Letter of Credit (calculated
separately for each Letter of Credit) at the rate per annum equal to the
Applicable Margin in effect from time to time for LIBOR Loans, provided that
each Letter of



                                      -30-
<PAGE>

Credit shall bear a minimum commission of $500. Each Letter of Credit shall be
deemed to be outstanding up to the full undrawn face amount of the Letter of
Credit until the Issuing Bank has received the canceled Letter of Credit or a
written cancellation of the Letter of Credit from the beneficiary of such Letter
of Credit in form and substance acceptable to the Issuing Bank, or for any
reductions in the amount of the Letter of Credit (other than from a drawing),
written notification from the beneficiary of such Letter of Credit. Such
commissions are payable quarterly in arrears on each Quarterly Date and upon
cancellation or expiration of each such Letter of Credit.

                           (ii) In addition to the foregoing, the Borrower shall
pay to the Issuing Bank, for its own account, fronting, amendment, transfer,
negotiating and other fees in accordance with the Issuing Bank's then current
fee policy generally applicable to letters of credit of the same or similar type
issued by the Issuing Bank.

                           (iii) In addition to the foregoing, the Borrower
shall pay to the Issuing Bank certain fees more specifically described in the
Reimbursement Agreement.

                  (c) The Borrower shall pay such other fees as are set forth in
the Fee Letter in the manner and on the dates specified therein to the extent
not paid prior to the Closing Date.

         Section 2.06 Several Obligations. The failure of any Lender to make any
Loan to be made by it or to provide funds for disbursements or reimbursements
under Letters of Credit on the date specified therefor shall not relieve any
other Lender of its obligation to make its Loan or provide funds on such date,
but no Lender shall be responsible for the failure of any other Lender to make a
Loan to be made by such other Lender or to provide funds to be provided by such
other Lender.

         Section 2.07 Notes. The Revolving Credit Loans (other than Swing Line
Loans) made by each Lender shall be evidenced by a single promissory note of the
Borrower in substantially the form of Exhibit A-1, dated (i) the Closing Date or
(ii) the effective date of an Assignment pursuant to Section 13.06(b), payable
to the order of such Lender in a principal amount equal to its Revolving Credit
Commitment as originally in effect and otherwise duly completed and such
substitute Notes as required by Section 13.06(b). The Swing Line Loans made by
the Swing Line Lender resulting from the advances under Section 2.01(c) shall be
evidenced by a promissory note of the Borrower in substantially the form of
Exhibit A-2, dated the Closing Date and payable to the Swing Line Lender in a
principal amount equal to the Swing Line Commitment. The date, amount, Type,
interest rate and Interest Period of each Loan made by each Lender, and all
payments made on account of the principal thereof, shall be recorded by such
Lender on its books for its Notes, and, prior to any transfer may be endorsed by
such Lender on the schedule attached to such Notes or any continuation thereof
or on any separate record maintained by such Lender. Failure to make any such
notation or to attach a schedule shall not affect any Lender's or the Borrower's
rights or obligations in respect of such Loans or affect the validity of such
transfer by any Lender of its Notes.

         Section 2.08 Prepayments.

                  (a) Voluntary Prepayments. The Borrower may prepay the Base
Rate Loans upon not less than one Business Day's prior notice to the
Administrative Agent (which shall promptly notify the Lenders), which notice
shall specify the prepayment date (which shall be a Business Day) and the amount
of the prepayment (which shall be at least $500,000 or any whole multiple of
$500,000 or, if less, the remaining aggregate principal balance outstanding on
the Notes) and shall be irrevocable and effective only upon receipt by the
Administrative Agent, provided that interest on the principal prepaid, accrued
to the prepayment date, shall be paid on the prepayment date. The Borrower may
prepay LIBOR Loans on the same conditions as for Base Rate Loans (except that
prior notice to the Administrative Agent shall be not less than three Business
Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be
subject to the terms of Section 5.05.

                  (b) Mandatory Prepayments.

                           (i) Revolving Credit Commitment Reductions. If, after
giving effect to any termination or reduction of the Aggregate Revolving Credit
Commitments pursuant to Section 2.03(b) or 2.03(c), the outstanding aggregate
principal amount of the Revolving Credit Loans and Swing Line Loans, plus the LC
Exposure, plus the Direct Pay Letter of Credit Exposure exceeds the Aggregate
Revolving Credit Commitments, the Borrower shall (i) prepay the Revolving Credit
Loans and Swing Line Loans on the date of such termination or reduction in an
aggregate principal amount equal to the excess, together with interest on the
principal amount paid accrued to the date of such prepayment and (ii) if any
excess remains after prepaying all of the Revolving Credit Loans and Swing Line
Loans because of LC Exposure and/or Direct Pay Letter of Credit Exposure, pay to
the Administrative Agent on behalf of the Lenders an amount equal to the excess
to be held as cash collateral as provided in Section 2.09(b) hereof.

                           (ii) Upon Transfers and Issuances of Equity. The
Borrower shall, and shall cause any Subsidiary to, apply an amount equal to 100%
of the net cash proceeds received from any (A) Transfers of the type referred to
in Section 9.16(iii) to the extent that during any consecutive 12-month period
such net cash proceeds exceed $2,500,000, based on the net book value of the
Property sold or the net proceeds received and (B) issuance by WCA Corp. or its
Subsidiaries of debt or equity securities to first, promptly prepay the
Revolving Credit Loans, and second, promptly provide cash collateral or, at the
Borrower's election so long as no Default has occurred and is continuing, effect
optional redemption of the Bonds in an amount not less than the Direct Pay
Letter of Credit Exposure as provided in the Reimbursement Agreement. Upon the
occurrence of any event requiring a mandatory prepayment to the Revolving Credit
Loans pursuant to this Section 2.08(b)(ii) other than the issuance by WCA Corp.
of equity securities in connection with an initial public offering consummated
on or about the Closing Date, the Aggregate Revolving Credit Commitments shall
automatically reduce by an amount equal to such net cash proceeds received in
connection with the transactions described in clauses (A) and (B) above.
Notwithstanding the foregoing, the Borrower may elect to provide cash collateral
in lieu of the prepayment required pursuant to this clause (ii) to the extent
any LIBOR Loans are outstanding until termination of the applicable Interest
Period so long as (A) the pledge of cash collateral does not affect the
tax-exempt nature of the Bonds or result in



                                      -32-
<PAGE>

the Bonds being characterized as so called "arbitrage bonds," and (B) no Default
has occurred and is continuing.

                           (iii) Generally. Prepayments permitted or required
under this Section 2.08 shall be without premium or penalty, except as required
under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the
Revolving Credit Loans may be reborrowed subject to the then effective Aggregate
Revolving Credit Commitments. Any voluntary prepayments shall be applied to the
Loans as specified by Borrower.

                           (iv) Transfers of Non-Core Assets. The Borrower
shall, and shall cause any Guarantor or Subsidiary to, apply an amount equal to
100% of the net cash proceeds received from any Transfers of the type referred
to in Section 9.16(iv) to first, promptly prepay the Revolving Credit Loans and
second, promptly provide cash collateral. Notwithstanding the foregoing, the
Borrower may elect to provide cash collateral in lieu of the prepayment required
pursuant to this clause (vi) to the extent any LIBOR Loans are outstanding until
termination of the applicable Interest Period so long as no Default has occurred
and is continuing.

         Section 2.09 Assumption of Risks. The Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit or the Direct Pay
Letter of Credit or any transferee thereof with respect to its use of such
Letter of Credit or the Direct Pay Letter of Credit. Neither the Issuing Bank
(except in the case of gross negligence or willful misconduct on the part of the
Issuing Bank or any of its employees), nor any Lender shall be responsible for
the validity, sufficiency (except for the sufficiency on their face) or
genuineness of certificates or other documents or any endorsements thereon, even
if such certificates or other documents should in fact prove to be invalid,
insufficient, fraudulent or forged; for errors, omissions, interruptions or
delays in transmissions or delivery of any messages by mail, telex, or
otherwise, whether or not they be in code; for errors in translation or for
errors in interpretation of technical terms; the validity or sufficiency (except
for the sufficiency on their face) of any instrument transferring or assigning
or purporting to transfer or assign any Letter of Credit or the Direct Pay
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason;
the failure of any beneficiary or any transferee of any Letter of Credit or the
Direct Pay Letter of Credit to comply fully with the underlying conditions
required in order to draw upon any Letter of Credit or the Direct Pay Letter of
Credit; or for any other consequences arising from causes beyond the Issuing
Bank's control or the control of the Issuing Bank's correspondents. In addition,
neither the Issuing Bank, the Administrative Agent nor any Lender shall be
responsible for any error, neglect, or default of any of the Issuing Bank's
correspondents; and none of the above shall affect, impair or prevent the
vesting of any of the Issuing Bank's, the Administrative Agent's or any Lender's
rights or powers hereunder or under the Letter of Credit Agreements or this
Agreement, all of which rights shall be cumulative. The Issuing Bank and its
correspondents may accept certificates or other documents that appear on their
face to comply with the terms of the applicable Letter of Credit or the Direct
Pay Letter of Credit, without responsibility for further investigation of any
matter contained therein regardless of any notice or information to the
contrary. In furtherance and not in limitation of the foregoing provisions, the
Borrower agrees that any action, inaction or omission taken or not taken by the
Issuing Bank or by any correspondent for the Issuing Bank in good faith in
connection with any Letter of Credit, the Direct Pay Letter of Credit, or any
related drafts, certificates, documents or instruments, shall be



                                      -33-
<PAGE>

binding on the Borrower and shall not put the Issuing Bank or its correspondents
under any resulting liability to the Borrower in the absence of gross negligence
or willful misconduct on the part of any such Person.

         Section 2.10 Obligation to Reimburse and to Prepay.

                  (a) If a disbursement by the Issuing Bank is made under any
Letter of Credit, the Borrower shall pay to the Administrative Agent within two
Business Days after notice of any such disbursement is received by the Borrower,
the amount of each such disbursement made by the Issuing Bank under the Letter
of Credit (if such payment is not sooner effected as may be required under this
Section 2.10 or under other provisions of the Letter of Credit), together with
interest on the amount disbursed from and including the date of disbursement
until payment in full of such disbursed amount at a varying rate per annum equal
to (i) the then applicable interest rate for Base Rate Loans (but in no event to
exceed the Highest Lawful Rate) through the second Business Day after notice of
such disbursement is received by the Borrower and (ii) thereafter, the
Post-Default Rate for Base Rate Loans (but in no event to exceed the Highest
Lawful Rate) for the period from and including the third Business Day following
the date of such disbursement to and including the date of repayment in full of
such disbursed amount. Subject to Section 13.14, the obligations of the Borrower
or Waste Corporation Texas, if applicable, under this Agreement with respect to
each Letter of Credit and the Direct Pay Letter of Credit shall be absolute,
unconditional and irrevocable and shall be paid or performed strictly in
accordance with the terms of this Agreement under all circumstances whatsoever,
including, without limitation, but only to the fullest extent permitted by
applicable law, the following circumstances: (i) any lack of validity or
enforceability of this Agreement, any Letter of Credit, the Direct Pay Letter of
Credit or any of the Security Instruments; (ii) any amendment or waiver of
(including any default), or any consent to departure from this Agreement (except
to the extent permitted by any amendment or waiver), any Letter of Credit, the
Direct Pay Letter of Credit or any of the Security Instruments; (iii) the
existence of any claim, set-off, defense or other rights which the Borrower or
any Guarantor, if applicable, may have at any time against the beneficiary of
any Letter of Credit or the Direct Pay Letter of Credit or any transferee of any
Letter of Credit or the Direct Pay Letter of Credit (or any Persons for whom any
such beneficiary or any such transferee may be acting), the Issuing Bank, the
Administrative Agent, any Lender or any other Person, whether in connection with
this Agreement, any Letter of Credit, the Direct Pay Letter of Credit, the
Security Instruments, the transactions contemplated hereby or any unrelated
transaction; (iv) any statement, certificate, draft, notice or any other
document presented under any Letter of Credit or the Direct Pay Letter of Credit
proves to have been forged, fraudulent, insufficient (so long as it is not
insufficient on its face) or invalid in any respect or any statement therein
proves to have been untrue or inaccurate in any respect whatsoever; (v) payment
by the Issuing Bank under any Letter of Credit or the Direct Pay Letter of
Credit against presentation of a draft or certificate which appears on its face
to comply, but does not comply, with the terms of such Letter of Credit or the
Direct Pay Letter of Credit; and (vi) any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing. Notwithstanding
anything in this Agreement to the contrary, the Borrower will not be liable for
payment or performance that results from the gross negligence or willful
misconduct of the Issuing Bank, except to the extent the Borrower or any
Subsidiary actually recovers (net of costs and expenses) any proceeds (net of
any expenses incurred for such recovery) for itself or the Issuing Bank of any
payment made by the Issuing Bank in connection with such gross negligence or
willful misconduct.



                                      -34-
<PAGE>

                  (b) In the event of the occurrence of any Event of Default, a
payment or prepayment pursuant to Section 2.08(b) or the maturity of the Notes,
whether by acceleration or otherwise, an amount equal to the LC Exposure (or the
excess in the case of Section 2.08(b)), shall be deemed to be forthwith due and
owing by the Borrower to the Administrative Agent as of the date of any such
occurrence; and the Borrower's obligation to pay such amount shall be absolute
and unconditional, without regard to whether any beneficiary of any such Letter
of Credit has attempted to draw down all or a portion of such amount under the
terms of a Letter of Credit, and, to the fullest extent permitted by applicable
law, shall not be subject to any defense or be affected by a right of set-off,
counterclaim or recoupment which the Borrower may now or hereafter have against
any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or
any other Person for any reason whatsoever. Such payments shall be held by the
Administrative Agent on behalf of the Issuing Bank and the Lenders as cash
collateral securing the LC Exposure in an account or accounts at the Principal
Office; and the Borrower hereby grants to and by its deposit with the
Administrative Agent grants to the Administrative Agent a security interest in
such cash collateral. In the event of any such payment by the Borrower of
amounts contingently owing under outstanding Letters of Credit and in the event
that thereafter drafts or other demands for payment complying with the terms of
such Letters of Credit are not made prior to the respective expiration dates
thereof, the Administrative Agent agrees, if no Event of Default has occurred
and is continuing or if no other amounts are outstanding under this Agreement,
the Notes or the Security Instruments, to remit to the Borrower amounts for
which the contingent obligations evidenced by the Letters of Credit have ceased.

                  (c) Each Lender severally and unconditionally agrees that it
shall promptly reimburse the Issuing Bank an amount equal to such Lender's
Percentage Share of any disbursement made by the Issuing Bank (i) under any
Letter of Credit that is not reimbursed according to this Section 2.10 or (ii)
under the Direct Pay Letter of Credit that is not reimbursed according to the
Reimbursement Agreement.

                  (d) Notwithstanding anything to the contrary contained herein,
subject to availability under the Swing Line Commitment, to the extent the
Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit
within two Business Days after notice of such disbursement has been received by
the Borrower, the amount of such Letter of Credit reimbursement obligation shall
automatically be funded by the Swing Line Lender as a Swing Line Loan hereunder
and used by the Swing Line Lender to pay such Letter of Credit reimbursement
obligation. To the extent the funding of such Letter of Credit reimbursement
obligation as a Swing Line Loan would cause the aggregate amount of all Swing
Line Loans outstanding to exceed the Swing Line Commitment or the Swing Line
Lender does not desire to make a Swing Line Loan for such purpose, such Letter
of Credit reimbursement obligation shall not be funded as a Swing Line Loan, but
instead shall be funded as a Revolving Credit Loan.

         Section 2.11 Lending Offices. The Loans of each Type made by each
Lender shall be made and maintained at such Lender's Applicable Lending Office
for Loans of such Type.

                                  ARTICLE III

                       PAYMENTS OF PRINCIPAL AND INTEREST

         Section 3.01 Repayment of Loans.

                  (a) Revolving Credit Loans. On the Termination Date the
Borrower shall repay the outstanding principal amount of the Revolving Credit
Notes.

                  (b) Swing Line Loans. The principal amount of each advance of
a Swing Line Loan (together with all interest accrued thereon until the date of
payment) shall be repaid pursuant to the terms of Section 2.01(c).

                  (c) Direct Pay Letter of Credit. The principal amount of the
Direct Pay Letter of Credit shall be reduced pursuant to the Reimbursement
Agreement.

                  (d) Generally. The Borrower will pay to the Administrative
Agent, for the account of each Lender, the principal payments required by this
Section 3.01.

         Section 3.02 Interest.

                  (a) Interest Rates. The Borrower will pay to the
Administrative Agent, for the account of each Lender, interest on the unpaid
principal amount of each Loan made by such Lender for the period commencing on
the date such Loan is made to, but excluding, the date such Loan shall be paid
in full, at the following rates per annum:

                           (i) if such a Loan is a Base Rate Loan, the Base Rate
(as in effect from time to time) plus the Applicable Margin, but in no event to
exceed the Highest Lawful Rate; and

                           (ii) if such a Loan is a LIBOR Loan, for each
Interest Period relating thereto, the LIBOR Rate for such Loan plus the
Applicable Margin (as in effect from time to time), but in no event to exceed
the Highest Lawful Rate.

                  (b) Post-Default Rate. Notwithstanding the foregoing, the
Borrower will pay to the Administrative Agent, for the account of each Lender
interest at the applicable Post-Default Rate on any principal of any Loan made
by such Lender, and (to the fullest extent permitted by law) on any other
amounts due and payable or that become due and payable by the Borrower
hereunder, under any Loan Document or under any Note held by such Lender to or
for account of such Lender, for the period commencing on the date of an Event of
Default (or the date any such other amount becomes due and payable) until the
same is paid in full or all Events of Default are cured or waived. If an Event
of Default under Section 10.01(a) occurs, the operation of this Section 3.02(b)
shall be automatic, but if the only Events of Default are Events of Default
other than under Section 10.01(a), the operation of this Section 3.02(b) shall
require the election of the Majority Lenders to accrue interest at the
Post-Default Rate.

                  (c) Due Dates. Accrued interest on Base Rate Loans shall be
payable monthly on the first day of each month commencing on [JUNE 1, 2004], and
accrued interest on



                                      -36-
<PAGE>

each LIBOR Loan shall be payable on the last day of the Interest Period therefor
and, if such Interest Period is longer than three months at three-month
intervals following the first day of such Interest Period, except that interest
payable at the Post-Default Rate shall be payable from time to time on demand
and interest on any LIBOR Loan that is converted into a Base Rate Loan (pursuant
to Section 5.04) shall be payable on the date of conversion (but only to the
extent so converted). Any accrued and unpaid interest on the Revolving Credit
Loans on the Termination Date shall be paid on such date. Accrued interest on
Swing Line Loans shall be paid pursuant to Section 3.01(c).

                  (d) Determination of Rates. Promptly after the determination
of any interest rate provided for herein or any change therein, the
Administrative Agent shall notify the Lenders to which such interest is payable
and the Borrower thereof. Each determination by the Administrative Agent of an
interest rate or fee hereunder shall, except in cases of manifest error, be
final, conclusive and binding on the parties.

                                   ARTICLE IV

                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

         Section 4.01 Payments. Except to the extent otherwise provided herein,
all payments of principal, interest and other amounts to be made by the Borrower
or Waste Corporation Texas, if applicable, under this Agreement, the Notes, the
Direct Pay Letter of Credit and the Letter of Credit Agreements shall be made in
Dollars, in immediately available funds, to the Administrative Agent at such
account as the Administrative Agent shall specify by notice to the Borrower from
time to time, not later than 11:00 a.m. (Central time) on the date on which such
payments shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day). Such
payments shall be made without (to the fullest extent permitted by applicable
law) defense, set-off or counterclaim. Each payment received by the
Administrative Agent under this Agreement or any Note for account of a Lender
shall be paid promptly to such Lender in immediately available funds. Except as
otherwise provided in the definition of "Interest Period", if the due date of
any payment under this Agreement or any Note would otherwise fall on a day which
is not a Business Day such date shall be extended to the next succeeding
Business Day and interest shall be payable for any principal so extended for the
period of such extension. At the time of each payment to the Administrative
Agent of any principal of or interest on any borrowing, the Borrower shall
notify the Administrative Agent of the Loans to which such payment shall apply.
In the absence of such notice the Administrative Agent may specify the Loans to
which such payment shall apply, but to the extent possible such payment or
prepayment will be applied first to the Loans comprised of Base Rate Loans.

         Section 4.02 Pro Rata Treatment. Except to the extent otherwise
provided herein each Lender agrees that: (i) each borrowing from the Lenders
under Section 2.01 and each continuation and conversion under Section 2.02 shall
be made from the Lenders pro rata in accordance with their Percentage Share,
each payment of commitment fee or other fees under Section 2.05(a) and Section
2.05(b)(i) shall be made for account of the Lenders pro rata in accordance with
their Percentage Share, and each termination or reduction of the amount of the
Aggregate Revolving Credit Commitments under Section 2.03(b) shall be applied to
the



                                      -37-
<PAGE>

Commitment of each Lender, pro rata according to the amounts of its respective
Commitment; (ii) each payment of principal of Loans by the Borrower shall be
made for account of the Lenders pro rata in accordance with the respective
unpaid principal amount of the Loans held by the Lenders; and (iii) each payment
of interest on Loans by the Borrower shall be made for account of the Lenders
pro rata in accordance with the amounts of interest due and payable to the
respective Lenders; and (iv) each reimbursement by the Borrower or Waste
Corporation Texas, if applicable, of disbursements under the Direct Pay Letter
of Credit or Letters of Credit shall be made for account of the Issuing Bank or,
if funded by the Lenders, pro rata for the account of the Lenders, in accordance
with the amounts of reimbursement obligations due and payable to each respective
Lender.

         Section 4.03 Computations. Interest on all LIBOR Loans shall be
computed on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day) occurring in the period for which such
interest is payable, unless such calculation would exceed the Highest Lawful
Rate, in which case interest shall be calculated on the per annum basis of a
year of 365 or 366 days, as the case may be. All computations of interest on
Base Rate Loans and fees shall be computed on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed (including the first day but
excluding the last day).

         Section 4.04 Non-receipt of Funds by the Administrative Agent. Unless
the Administrative Agent shall have been notified by a Lender or the Borrower
prior to the date on which such notifying party is scheduled to make payment to
the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or
a payment under the Direct Pay Letter of Credit or a Letter of Credit to be made
by it hereunder or (in the case of the Borrower or Waste Corporation Texas) a
payment to the Administrative Agent for account of one or more of the Lenders
hereunder (such payment being herein called the "Required Payment"), which
notice shall be effective upon receipt, that it does not intend to make the
Required Payment to the Administrative Agent, the Administrative Agent may
assume that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof available to
the intended recipient(s) on such date and, if such Lender or the Borrower or
Waste Corporation Texas (as the case may be) has not in fact made the Required
Payment to the Administrative Agent, the recipient(s) of such payment shall, on
demand, repay to the Administrative Agent the amount so made available together
with interest thereon in respect of each day during the period commencing on the
date such amount was so made available by the Administrative Agent until, but
excluding, the date the Administrative Agent recovers such amount at a rate per
annum which, for any Lender as recipient, will be equal to the Federal Funds
Rate, and for the Borrower or Waste Corporation Texas as recipient, will be
equal to the Base Rate plus the Applicable Margin.

         Section 4.05 Set-off, Sharing of Payments, Etc. (a) The Borrower agrees
that, in addition to (and without limitation of) any right of set-off, bankers'
lien or counterclaim a Lender may otherwise have, each Lender shall have the
right and be entitled (after consultation with the Administrative Agent), at its
option, to offset balances held by it or by any of such Lender's Affiliates for
account of the Borrower at any of its offices, in Dollars or in any other
currency, against any principal of or interest on any of such Lender's Loans, or
any other amount payable to such Lender hereunder, which is not paid when due
(regardless of whether such balances are then due to the Borrower), in which
case it shall promptly notify the Borrower and the



                                      -38-
<PAGE>

Administrative Agent thereof, provided that, to the extent permitted by law,
such Lender's failure to give such notice shall not affect the validity thereof.

                  (b) If any Lender shall obtain payment of any principal of or
interest on any Loan made by it to the Borrower under this Agreement (or
reimbursement by the Borrower or Waste Corporation Texas as to any Letter of
Credit or the Direct Pay Letter of Credit) through the exercise of any right of
set-off, banker's lien or counterclaim or similar right or otherwise, and, as a
result of such payment, such Lender shall have received a greater percentage of
the principal or interest (or reimbursement) then due hereunder by the Borrower
or Waste Corporation Texas, if applicable, to such Lender than the percentage
received by any other Lenders, it shall promptly (i) notify the Administrative
Agent and each other Lender thereof and (ii) purchase from such other Lenders
participations in (or, if and to the extent specified by such Lender, direct
interests in) the Loans (or participations in Letters of Credit or the Direct
Pay Letter of Credit) made by such other Lenders (or in interest due thereon, as
the case may be) in such amounts, and make such other adjustments from time to
time as shall be equitable, to the end that all the Lenders shall share the
benefit of such excess payment (net of any expenses which may be incurred by
such Lender in obtaining or preserving such excess payment) pro rata in
accordance with the unpaid principal and/or interest on the Loans held by each
of the Lenders (or reimbursements of Letters of Credit or the Direct Pay Letter
of Credit). To such end all the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored. The Borrower agrees that any Lender
so purchasing a participation (or direct interest) in the Loans made by other
Lenders (or in interest due thereon, as the case may be) may exercise all rights
of set-off, banker's lien, counterclaim or similar rights with respect to such
participation as fully as if such Lender were a direct holder of Loans (or
Letters of Credit or the Direct Pay Letter of Credit) in the amount of such
participation. Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of the Borrower. If under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.05 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.05 to share the benefits
of any recovery on such secured claim.

         Section 4.06 Taxes.

                  (a) Payments Free and Clear. Any and all payments by the
Borrower or any Guarantor hereunder shall be made, in accordance with Section
4.01, free and clear of and without deduction for any and all present or future
taxes, levies, imposts, deductions, charges or withholdings, and all liabilities
with respect thereto, excluding, in the case of each Lender, the Issuing Bank
and the Administrative Agent, taxes imposed on or measured by its income, and
franchise or similar taxes imposed on it, by any jurisdiction, 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 taxes imposed by reason of its failure to comply with any
applicable certification, identification, information, documentation or other
reporting requirement (all such non-excluded



                                      -39-
<PAGE>

taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder to the Lenders,
the Issuing Bank or the Administrative Agent (i) the sum payable shall be
increased by the amount necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
4.06) such Lender, the Issuing Bank or the Administrative Agent (as the case may
be) shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxing authority or
other Governmental Authority in accordance with applicable law.

                  (b) Other Taxes. In addition, to the fullest extent permitted
by applicable law, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, any
Assignment or any Security Instrument (hereinafter referred to as "Other
Taxes").

                  (c) Indemnification. To the fullest extent permitted by
applicable law, the Borrower will indemnify each Lender and the Issuing Bank and
the Administrative Agent for the full amount of Taxes and Other Taxes
(including, but not limited to, any Taxes or Other Taxes imposed by any
Governmental Authority on amounts payable under this Section 4.06) paid by such
Lender, the Issuing Bank or the Administrative Agent (on their behalf or on
behalf of any Lender), as the case may be, and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted
unless the payment of such Taxes was not correctly or legally asserted and such
Lender's payment of such Taxes or Other Taxes was the result of its gross
negligence or willful misconduct. Any payment pursuant to such indemnification
shall be made within 30 days after the date any Lender, the Issuing Bank or the
Administrative Agent, as the case may be, makes written demand therefor setting
forth the basis for such request.

                  (d) Refunds and Benefits. If any Lender, the Issuing Bank or
the Administrative Agent receives a refund or credit in respect of any Taxes or
Other Taxes for which such Lender, Issuing Bank or the Administrative Agent has
received payment from the Borrower (whether under Sections 4.06(a) or (c) or
otherwise), and to the extent that such payment by the Borrower reduced the tax
burden that such Lender, the Issuing Bank or the Administrative Agent was or
shall be required to pay (such tax burden reduction hereinafter called the "tax
benefit"), such Lender, Issuing Bank or the Administrative Agent, as the case
may be, shall promptly notify the Borrower of such refund, credit or tax benefit
and shall, if no Default or Event of Default has occurred and is continuing
promptly thereafter (or promptly upon receipt or realization, if the Borrower
has requested application for such refund, credit or tax benefit pursuant
hereto), pay an amount equal to such refund, credit or tax benefit to the
Borrower without interest (but with any interest so refunded or credited),
provided that the Borrower, upon the request of such Lender, the Issuing Bank or
the Administrative Agent, agrees to return such refund, credit or tax benefit
(plus penalties, interest or other charges) to such Lender or the Administrative
Agent to the extent such Lender or the Administrative Agent is required to repay
such refund, credit or tax benefit (plus penalties, interest or other charges).

<PAGE>

                  (e) Lender Representations.

                           (i) Each Lender represents that it is either (1) a
banking association or corporation organized under the laws of the United States
of America or any state thereof or (2) it is entitled to complete exemption from
United States withholding tax imposed on or with respect to any payments,
including fees, to be made to it pursuant to this Agreement (A) under an
applicable provision of a tax convention to which the United States of America
is a party or (B) because it is acting through a branch, agency or office in the
United States of America and any payment to be received by it hereunder is
effectively connected with a trade or business in the United States of America.
Each Lender that is not a banking association or corporation organized under the
laws of the United States of America or any state thereof (each, a "Non-U. S.
Lender") agrees to provide to the Borrower and the Administrative Agent on the
Closing Date, or on the date of its delivery of the Assignment pursuant to which
it becomes a Lender, and at such other times as required by United States law or
as the Borrower or the Administrative Agent shall reasonably request, two
accurate and complete original signed copies of either (A) Internal Revenue
Service Form W-8ECI (or successor form) certifying that all payments to be made
to it hereunder will be effectively connected to a United States trade or
business (the "Form W-8ECI Certification") or (B) Internal Revenue Service Form
W-8BEN (or successor form) certifying that it is entitled to the benefit of a
provision of a tax convention to which the United States of America is a party
which completely exempts from United States withholding tax all payments to be
made to it hereunder (the "Form W-8BEN Certification"). In addition, each Lender
agrees that if it previously filed a Form W-8ECI Certification, it will deliver
to the Borrower and the Administrative Agent a new Form W-8ECI Certification
prior to the first payment date occurring in each of its subsequent taxable
years; and if it previously filed a Form W-8BEN Certification, it will deliver
to the Borrower and the Administrative Agent a new certification prior to the
first payment date falling in the third year following the previous filing of
such certification. Each Lender also agrees to deliver to the Borrower and the
Administrative Agent such other or supplemental forms as may at any time be
required as a result of changes in applicable law or regulation in order to
confirm or maintain in effect its entitlement to exemption from United States
withholding tax on any payments hereunder, provided that the circumstances of
such Lender at the relevant time and applicable laws permit it to do so. If a
Lender determines, as a result of any change in either (i) a Governmental
Requirement or (ii) its circumstances, that it is unable to submit any form or
certificate that it is obligated to submit pursuant to this Section 4.06, or
that it is required to withdraw or cancel any such form or certificate
previously submitted, it shall promptly notify the Borrower and the
Administrative Agent of such fact. If a Lender is organized under the laws of a
jurisdiction outside the United States of America, unless the Borrower and the
Administrative Agent have received a Form W-8BEN Certification or Form W-8ECI
Certification satisfactory to them indicating that all payments to be made to
such Lender hereunder are not subject to United States withholding tax, the
Borrower shall withhold taxes from such payments at the applicable statutory
rate. Each Lender agrees to indemnify and hold harmless the Borrower or
Administrative Agent, as applicable, from any United States taxes, penalties,
interest and other expenses, costs and losses incurred or payable by (i) the
Administrative Agent or the Borrower as a result of such Lender's failure to
submit any form or certificate that it is required to provide pursuant to this
Section 4.06 or (ii) the Borrower or the Administrative Agent as a result of
their reliance on any such form or certificate which such Lender has provided to
them pursuant to this Section 4.06.



                                      -41-
<PAGE>

                           (ii) For any period with respect to which a Lender
has failed to provide the Borrower with the form required pursuant to this
Section 4.06, if any, (other than if such failure is due to (x) a retroactive
change in a Governmental Requirement or (y) a Governmental Requirement occurring
subsequent to the date on which a form originally would have been required to be
provided eliminating such requirement), such Lender shall not be entitled to
indemnification under this Section 4.06 with respect to taxes imposed by the
United States which taxes would not have been imposed but for such failure to
provide such forms; provided, however, that if a Lender, which is otherwise
exempt from or subject to a reduced rate of withholding tax, becomes subject to
taxes because of its failure to deliver a form required hereunder, the Borrower
shall take such steps as such Lender shall reasonably request to assist such
Lender to recover such taxes.

                           (iii) The Borrower shall not be required to pay any
additional amounts to any Non-U.S. Lender in respect of United States Federal
withholding tax pursuant to this Section 4.06 to the extent that (1) the
obligation to withhold amounts with respect to such tax existed on the date such
Non-U.S. Lender became a party to this Agreement, or (2) with respect to
payments made to a different lending office designated by such Non-U.S. Lender
as its applicable lending office (the "New Lending Office"), the date such
Non-U.S. Lender designated such New Lending Office with respect to any
Obligations.

                           (iv) Any Lender claiming any additional amounts
payable pursuant to this Section 4.06 shall use reasonable efforts (consistent
with legal and regulatory restrictions) to file any certificate or document
requested by the Borrower or the Administrative Agent or to change the
jurisdiction of its Applicable Lending Office or to contest any tax imposed, and
take such other reasonable measures as are necessary if the making of such a
filing, change, contest or action with respect to such tax or withholding would
avoid the need for or reduce the amount of any such additional amounts that may
thereafter accrue and would not, in the sole determination of such Lender, be
otherwise disadvantageous to such Lender.

                                   ARTICLE V

                                CAPITAL ADEQUACY

         Section 5.01 Additional Costs.

                  (a) LIBOR Regulations, etc. The Borrower shall pay directly to
each Lender from time to time such amounts as such Lender may determine to be
necessary to compensate such Lender for any costs which it reasonably determines
are attributable to its making or maintaining of any LIBOR Loans or issuing or
participating in Letters of Credit or the Direct Pay Letter of Credit hereunder
or its obligation to make any LIBOR Loans or issue or participate in any Letters
of Credit or the Direct Pay Letter of Credit hereunder, or any reduction in any
amount receivable by such Lender hereunder in respect of any of such LIBOR
Loans, Letters of Credit, the Direct Pay Letter of Credit or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs"), resulting from any Regulatory Change which: (i)
changes the basis of taxation of any amounts payable to such Lender under this
Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit
or the Direct Pay Letter of Credit (other than taxes imposed on or measured by
the overall net income



                                      -42-
<PAGE>

of such Lender or of its Applicable Lending Office for any of such LIBOR Loans);
or (ii) imposes or modifies any reserve, special deposit, minimum capital,
capital ratio or similar requirements relating to any extensions of credit or
other assets of, or any deposits with or other liabilities of such Lender, or
the Commitment or Loans of such Lender or the London interbank market (but
excluding the Reserve Requirement to the extent it is included in the LIBOR
Rate) to the extent not covered by Section 5.06(c); or (iii) imposes any other
condition affecting this Agreement or any Note (or any of such extensions of
credit or liabilities) or such Lender's Commitment or Loans. Each Lender will
notify the Administrative Agent and the Borrower of any event occurring after
the Closing Date which will entitle such Lender to compensation pursuant to this
Section 5.01(a) as promptly as practicable after it obtains knowledge thereof
and determines to request such compensation, and will designate a different
Applicable Lending Office for the Loans of such Lender affected by such event if
such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender, provided that such Lender shall have no
obligation to so designate an Applicable Lending Office located in the United
States. If any Lender requests compensation from the Borrower under this Section
5.01(a), the Borrower may, by notice to such Lender, suspend the obligation of
such Lender to make additional Loans of the Type with respect to which such
compensation is requested until the Regulatory Change giving rise to such
request ceases to be in effect (in which case the provisions of Section 5.04
shall be applicable).

                  (b) Regulatory Change. Without limiting the effect of the
provisions of Section 5.01(a), in the event that at any time (by reason of any
Regulatory Change or any other circumstances arising after the Closing Date
affecting (A) any Lender, (B) the London interbank market or (C) such Lender's
position in such market), the LIBOR Rate, as determined reasonably and in good
faith by such Lender, will not adequately and fairly reflect the cost to such
Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to
the Borrower and the Administrative Agent, the obligation of such Lender to make
additional LIBOR Loans shall be suspended until such Regulatory Change or other
circumstances ceases to be in effect (in which case the provisions of Section
5.04 shall be applicable).

                  (c) Capital Adequacy. Without limiting the effect of the
foregoing provisions of this Section 5.01 (but without duplication), the
Borrower shall pay directly to any Lender from time to time on request such
amounts as such Lender may reasonably determine to be necessary to compensate
such Lender or its parent or holding company for any costs which it determines
are attributable to the maintenance by such Lender or its parent or holding
company (or any Applicable Lending Office), pursuant to any Governmental
Requirement following any Regulatory Change, of capital in respect of its
Commitment, its Notes, or its Loans or any interest held by it in any Letter of
Credit or the Direct Pay Letter of Credit. The amount of such compensation shall
be an amount equal to any reduction of the rate of return on assets or equity of
such Lender or its parent or holding company (or any Applicable Lending Office)
by virtue of such Regulatory Change to a level below that which such Lender or
its parent or holding company (or any Applicable Lending Office) could have
achieved but for such Regulatory Change to a Governmental Requirement. Such
Lender will notify the Borrower and the Administrative Agent that it is entitled
to compensation pursuant to this Section 5.01(c) as promptly as practicable
after it determines to request such compensation.



                                      -43-
<PAGE>

                  (d) Compensation Procedure. Any Lender notifying the Borrower
of the incurrence of Additional Costs under this Section 5.01 shall in such
notice to the Borrower and the Administrative Agent set forth in reasonable
detail the basis and amount of its request for compensation. Determinations and
allocations by each Lender for purposes of this Section 5.01 of the effect of
any Regulatory Change pursuant to Section 5.01(a) or (b), or of the effect of
capital maintained pursuant to Section 5.01(c), on its costs or rate of return
of maintaining Loans or its obligation to make Loans or issue Letters of Credit
or the Direct Pay Letter of Credit, or on amounts receivable by it in respect of
Loans or Letters of Credit or the Direct Pay Letter of Credit, and of the
amounts required to compensate such Lender under this Section 5.01, shall be
conclusive and binding for all purposes, provided that such determinations and
allocations are made on a reasonable basis. Any request for additional
compensation under this Section 5.01 shall be paid by the Borrower within 30
days of the receipt by the Borrower of the notice described in this Section
5.01(d).

         Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary
notwithstanding, if, on or prior to the determination of any LIBOR Rate for any
Interest Period:

                  (a) the Administrative Agent determines (which determination
shall be conclusive, absent manifest error) that quotations of interest rates
for the relevant deposits referred to in the definition of "LIBOR Rate" in
Section 1.02 are not being provided in the relevant amounts or for the relevant
maturities for purposes of determining rates of interest for LIBOR Loans as
provided herein; or

                  (b) the Administrative Agent reasonably determines (which
determination shall be conclusive, absent manifest error) that the relevant
rates of interest referred to in the definition of "LIBOR Rate" in Section 1.02
upon the basis of which the rate of interest for LIBOR Loans for such Interest
Period is to be determined are not sufficient to adequately cover the cost to
the Lenders of making or maintaining LIBOR Loans; then the Administrative Agent
shall give the Borrower prompt notice thereof, and so long as such condition
remains in effect, the Lenders shall be under no obligation to make additional
LIBOR Loans.

         Section 5.03 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain LIBOR
Loans hereunder, then such Lender shall promptly notify the Borrower thereof and
such Lender's obligation to make LIBOR Loans shall be suspended until such time
as such Lender may again make and maintain LIBOR Loans (in which case the
provisions of Section 5.04 shall be applicable). Any such Lender shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change
the jurisdiction of its Applicable Lending Office if the making of such change
would avoid such unlawfulness or the need for such suspension and would not, in
the sole determination of such Lender, be otherwise disadvantageous to such
Lender.

         Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03.
If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant
to Section 5.01, 5.02 or 5.03 ("Affected Loans"), all Affected Loans which would
otherwise be made by such Lender shall be made instead as Base Rate Loans (and,
if an event referred to in Section 5.01(b) or Section 5.03 has occurred which
affects existing LIBOR Loans and such Lender so requests




                                      -44-
<PAGE>

by notice to the Borrower, all Affected Loans of such Lender then outstanding
shall be automatically converted into Base Rate Loans on (a) the last day of the
applicable Interest Period to the extent permitted by law, and any then
outstanding LIBOR Loans shall continue to bear interest at the applicable LIBOR
Rate plus the Applicable Margin until the end of the applicable Interest Period
and thereafter shall be deemed converted to a Base Rate Loan so long as (i) no
Default of Event of Default has occurred and is continuing, (ii) it shall not be
illegal for such Lender to continue to maintain the LIBOR Loans and (iii) the
Borrower shall pay directly to each Lender such amounts as such Lender may
determine to be necessary to compensate such Lender for such Additional Costs,
or (b) on the date specified by such Lender in such notice) and, to the extent
that Affected Loans are so made as (or converted into) Base Rate Loans, all
payments of principal which would otherwise be applied to such Lender's Affected
Loans shall be applied instead to its Base Rate Loans.

         Section 5.05 Compensation. The Borrower shall pay to each Lender within
30 days of receipt of written request of such Lender (which request shall set
forth, in reasonable detail, the basis for requesting such amounts and which
shall be conclusive and binding for all purposes provided that such
determinations are made on a reasonable basis), such amount or amounts as shall
compensate it for any loss, cost, expense or liability which such Lender
reasonably determines are attributable to:

                           (i) any payment, prepayment or conversion of a LIBOR
Loan for any reason (including, without limitation, the acceleration of the
Loans pursuant to Section 10.02) on a date other than the last day of the
Interest Period for such Loan; or

                           (ii) any failure by the Borrower for any reason
(including but not limited to, the failure of any of the conditions precedent
specified in Article V to be satisfied) to borrow, continue or convert a LIBOR
Loan from such Lender on the date for such borrowing, continuation or conversion
specified in the relevant notice given pursuant to Section 2.02(c); provided,
however, that where such failure is attributable to the circumstances set forth
in Sections 5.01(b), 5.02 or 5.03 with respect to such Lender's inability or
determination not to make LIBOR Loans, no such compensation shall be required.
Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount so paid, prepaid or converted
or not borrowed for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date specified for such borrowing) at the
applicable rate of interest for such Loan provided for herein over (ii) the
interest component of the amount such Lender would have bid in the London
interbank market for Dollar deposits of leading banks in amounts comparable to
such principal amount and with maturities comparable to such period (as
reasonably determined by such Lender).

         Section 5.06 Time Limit; Etc.

                  (a) Time Limited. Notwithstanding anything to the contrary
contained in Sections 5.01 through 5.05, the Borrower shall not be required to
reimburse or pay any costs or expenses to any Lender as required by such
sections which have accrued more than 180 days



                                      -45-
<PAGE>

prior to such Lender's giving notice to the Borrower that such Lender has
suffered or incurred such costs or expenses.

                  (b) Non-Discriminatory Basis. None of the Lenders shall be
permitted to pass through to the Borrower costs and expenses under Sections 5.01
through 5.05 which are not also passed through by such Lender to other customers
of such Lender similarly situated when such customer is subject to documents
containing similar provisions as those contained in such Sections.

                  (c) Mitigation. Each Lender agrees that as soon as practicable
after a Responsible Officer with direct responsibility for such Lender's credit
relationship with such Lender becomes aware of the occurrence of an event or the
existence of a condition that would cause it to be affected under Sections 5.01
through 5.05, such Lender will give notice thereof to the Borrower, with a copy
to the Administrative Agent, and, to the extent so requested by the Borrower,
such Lender shall use reasonable efforts and take such actions as are reasonably
appropriate if as a result the additional monies which would otherwise be
required to be paid to such Lender 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
reasonably determined by such Lender, the taking of such actions would not
affect such Loans or such Lender or otherwise be disadvantageous to such Lender.

         Section 5.07 Replacement Lenders.

                  (a) Terminated Lenders. If any Lender has (i) required the
Borrower to make payments for Taxes under Section 4.06 or (ii) has notified the
Borrower and the Administrative Agent of its incurring Additional Costs under
Section 5.01(a) or other compensation under Section 5.01(c) or (iii) asserts
that it cannot under Section 5.01(b) or is illegal under Section 5.01(a) for it
to make and maintain LIBOR Loans when all other Lenders have not also made such
assertion, then the Borrower may, unless such Lender has notified the Borrower
and the Administrative Agent that the circumstances giving rise to such notice
no longer apply, terminate, in whole but not in part, the Commitment of any
Lender (the "Terminated Lender") at any time upon five Business Days' prior
written notice to the Terminated Lender and the Administrative Agent (such
notice referred to herein as a "Notice of Termination").

                  (b) Replacement Lenders. In order to effect the termination of
the Commitment of the Terminated Lender, the Borrower shall: (i) obtain an
agreement with one or more Lenders to increase their respective Commitment
and/or (ii) request any one or more other banking institutions to become parties
to this Agreement in place and instead of such Terminated Lender and agree to
accept a Commitment; provided, however, that such one or more other banking
institutions are reasonably acceptable to the Administrative Agent and become
parties by executing an Assignment (the Lenders or other banking institutions
that agree to accept in whole or in part the Commitment of the Terminated Lender
being referred to herein as the "Replacement Lenders"), such that the aggregate
increased and/or accepted Commitment of the Replacement Lenders under clauses
(i) and (ii) above equal the Commitment of the Terminated Lender.



                                      -46-
<PAGE>

                  (c) Content of Notice of Termination. The Notice of
Termination shall include the name of the Terminated Lender, the date the
termination will occur (the "Lender Termination Date"), and the Replacement
Lender or Replacement Lenders to which the Terminated Lender will assign its
Commitment and, if there will be more than one Replacement Lender, the portion
of the Terminated Lender's Commitment to be assigned to each Replacement Lender.

                  (d) Effecting Termination. On the Lender Termination Date, (i)
the Terminated Lender shall by execution and delivery of an Assignment assign
its Commitment to the Replacement Lender or Replacement Lenders indicated in the
Notice of Termination and shall assign to the Replacement Lender or Replacement
Lenders each of its Loans (if any) then outstanding and participation interests
in Letters of Credit and the Direct Pay Letter of Credit (if any) then
outstanding, (ii) the Terminated Lender shall endorse its Notes, payable without
recourse, representation or warranty, except in accordance with the Assignment,
to the order of the Replacement Lender or Replacement Lenders, (iii) the
Replacement Lender or Replacement Lenders shall purchase the Notes held by the
Terminated Lender at a price equal to the unpaid principal amount thereof plus
interest and facility and other fees accrued and unpaid to the Lender
Termination Date, and (iv) the Replacement Lender or Replacement Lenders will
thereupon succeed to and be substituted in all respects for the Terminated
Lender with like effect as if becoming a Lender pursuant to the terms of Section
13.06(b), and the Terminated Lender will have the rights and benefits of an
assignor under Section 13.06(b). To the extent not in conflict, the terms of
Section 13.06(b) shall supplement the provisions of this Section 5.07(d). For
each assignment made under this Section 5.07, the Replacement Lender shall pay
to the Administrative Agent the processing fee provided for in Section 13.06(b).
The Borrower will be responsible for the payment of any breakage costs
associated with termination of the Terminated Lender, as set forth in Section
5.05.

                  (k) Unaudited consolidated balance sheet of the Borrower as at
March 31, 2004 and the related consolidated statement of income, stockholders'
equity and cash flow for the portion of the fiscal year ended on such date, all

year-end adjustments).

                  (l) Such other documents, agreements, and instruments as the
Administrative Agent or any Lender or special counsel to the Administrative
Agent may reasonably request.

         Section 6.02 Initial and Subsequent Loans and Letters of Credit. The
obligation of the Lenders to make Loans (except as to Loans automatically funded
pursuant to Section 2.10(d)) to the Borrower upon the occasion of each borrowing
hereunder and to issue, renew, extend or reissue Letters of Credit for the
account of the Borrower (including the Initial Funding) is subject to the
further conditions precedent that, as of the date of such Loans and after giving
effect thereto:

                  (a) no Default shall exist;

                  (b) no Material Adverse Effect shall have occurred and be
continuing; and

                  (c) the representations and warranties made by the Borrower in
Article VII and by the Borrower and each Guarantor in the Security Instruments
shall be true on and as of the date of the making of such Loans or issuance,
renewal, extension or reissuance of a Letter of Credit with the same force and
effect as if made on and as of such date and immediately after giving effect to
such new borrowing, except to the extent such representations and warranties are
set forth as being related only to a specified date (e.g. "as of the Closing
Date") and were true and correct as of such specified date or the Majority
Lenders may expressly consent in writing to the contrary.

Each request for a borrowing or issuance, renewal, extension or reissuance of a
Letter of Credit by the Borrower hereunder shall constitute a certification by
the Borrower to the effect set forth in Section 6.02(c) (both as of the date of
such notice and, unless the Borrower otherwise notifies the Administrative Agent
prior to the date of and immediately following such borrowing or issuance,
renewal, extension or reissuance of a Letter of Credit as of the date thereof).

         Section 6.03 Conditions Precedent for the Benefit of Lenders. All
conditions precedent to the obligations of the Lenders to make any Loan are
imposed hereby solely for the benefit of the Lenders, and no other Person may
require satisfaction of any such condition precedent or be entitled to assume
that the Lenders will refuse to make any Loan in the absence of strict
compliance with such conditions precedent.

         Section 6.04 No Waiver. No waiver of any condition precedent shall
preclude the Administrative Agent or the Lenders from requiring such condition
to be met prior to making any subsequent Loan or preclude the Lenders from
thereafter declaring that the failure of the Borrower to satisfy such condition
precedent constitutes a Default.

                                  ARTICLE VII

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Administrative Agent and
the Lenders that (each representation and warranty herein is given as of the
Closing Date and shall be deemed repeated and reaffirmed on the dates of each
borrowing and issuance, renewal, extension or reissuance of a Letter of Credit
to the extent provided in Section 6.02):

         Section 7.01 Corporate Existence. Each of the Borrower and each
Subsidiary: (i) is a corporation, limited partnership or limited liability
company duly organized, legally existing and in good standing, if applicable,
under the laws of the jurisdiction of its organization; (ii) (x) has all
requisite power (corporate or otherwise), and (y) has all material governmental
licenses, authorizations, consents and approvals necessary to own its assets and
carry on its business as now being or as proposed to be conducted; and (iii) is
qualified to do business in all jurisdictions in which the nature of the
business conducted by it makes such qualification necessary, except in each case
referred to in clauses (ii) (y) and (iii), to the extent the failure so to do
could not reasonably be expected to have a Material Adverse Effect.

         Section 7.02 Financial Condition. The audited consolidated balance
sheet of Waste Corporation as at December 31, 2003 and the related consolidated
statement of income, stockholders' equity and cash flow for the fiscal year
ended on said date, with the opinion thereon of KPMG heretofore furnished to
each of the Lenders, are complete and correct and fairly present the
consolidated financial condition of Waste Corporation and its Consolidated
Subsidiaries as at said dates and the results of its operations for the fiscal
year, all in accordance with GAAP, as applied on a consistent basis. The
unaudited consolidated balance sheet of the Borrower as at March 31, 2004 and
the related consolidated statement of income, stockholders' equity and cash flow
for the portion of the fiscal year ended on such date are complete and correct
and fairly present the consolidated financial condition of the Borrower and its
Consolidated Subsidiaries as at said date, all in accordance with GAAP, as
applied on a consistent basis (subject to normal year-end adjustments). Neither
the Borrower nor any Subsidiary has on the Closing Date any material Debt,
contingent liabilities, liabilities for taxes, forward or long-term commitments
other than those customary in Borrower's business or unrealized or anticipated
losses from any unfavorable commitments, except as referred to or reflected or
provided for in the Financial Statements or in Schedule 7.02. Since March 31,
2004, there has been no change or event that could reasonably be expected to
have a Material Adverse Effect. Since the date of the Financial Statements,
neither the Properties of the Borrower or any Subsidiary have been affected as a
result of any fire, explosion, earthquake, flood, drought, windstorm, accident,
strike or other labor disturbance, embargo, requisition or taking of Property or
cancellation of contracts, permits or concessions by any Governmental Authority,
riot, activities of armed forces or acts of God or of any public enemy where
such event or matter could reasonably be expected to result in a Material
Adverse Effect.

         Section 7.03 Litigation. Except as disclosed to the Lenders in Schedule
7.03 hereto, at the Closing Date there is no litigation, legal, administrative
or arbitral proceeding, investigation or other action of any nature pending or,
to the knowledge of the Borrower threatened against or affecting the Borrower or
any Subsidiary which can reasonably be expected to result in any



                                      -50-
<PAGE>

judgment or liability against the Borrower or any Subsidiary not fully covered
by insurance (except for normal deductibles) and which could reasonably be
expected to have a Material Adverse Effect.

         Section 7.04 No Breach. Neither the execution and delivery of the Loan
Documents and the Related Documents, nor compliance with the terms and
provisions hereof will conflict with or result in a breach of, or require any
consent which has not been obtained as of the Closing Date under, the respective
charter or bylaws, partnership agreement, operating agreement or other
organizational documents, as the case may be, of the Borrower or any Subsidiary,
or, in any material respect, any Governmental Requirement or any material
agreement or instrument to which the Borrower or any Subsidiary is a party or by
which it is bound or to which it or its Properties are subject, or constitute a
default under any such agreement or instrument, or result in the creation or
imposition of any material Lien upon any of the revenues or assets of the
Borrower or any Subsidiary pursuant to the terms of any such agreement or
instrument other than the Liens created by the Loan Documents.

         Section 7.05 Authority. The Borrower and each Subsidiary have all
necessary power (corporate or otherwise) and authority to execute, deliver and
perform its obligations under the Related Documents to which it is a party; and
the execution, delivery and performance by the Borrower and each Subsidiary of
the Loan Documents and the Related Documents to which it is a party, have been
duly authorized by all necessary action (corporate or otherwise) on its part;
and the Related Documents constitute the legal, valid and binding obligations of
the Borrower and each Subsidiary, enforceable in accordance with their terms.

         Section 7.06 Approvals. No authorizations, approvals or consents of,
and no filings or registrations with, any Governmental Authority are necessary
for the execution, delivery or performance by the Borrower or any Subsidiary of
the Related Documents or for the validity or enforceability thereof, except for
(i) the recording and filing of the Security Instruments as required by this
Agreement and (ii) approvals by the applicable Governmental Authorities
(including the Issuer, the Attorney General of the State of Texas and the
Comptroller of Public Accounts of the State of Texas) with respect to the
transactions relating to the Installment Sale Agreement and issuance of the
Bonds.

         Section 7.07 Use of Loans. The proceeds of the Loans and the Direct Pay
Letter of Credit shall be used to (i) fund a portion of the transactions
contemplated hereby, (ii) refinance certain existing indebtedness of the
Borrower, (iii) pay fees and expenses incurred in connection with the
transactions contemplated hereby, (iv) provide working capital and general
business purpose needs of the Borrower and the Guarantors (other than the
Parent), (v) the funding of Qualified Acquisition Expenditures, Expansion
Expenditures, and Capital Expenditures permitted hereunder, (vi) make payments
pursuant to the Reimbursement Agreement and the Installment Sale Agreement, and
(vii) the funding of certain other expenditures approved by the Administrative
Agent from time to time. The Letters of Credit shall be used for general
business purposes of the Borrower and the Guarantors (other than the Parent).
The Borrower is not engaged principally, or as one of its important activities,
in the business of extending credit for the purpose, whether immediate,
incidental or ultimate, of buying or carrying margin stock (within the meaning
of Regulation T, U or X of the Board of Governors of the Federal Reserve




                                      -51-
<PAGE>

System) and no part of the proceeds of any Loan hereunder will be used to buy or
carry any margin stock.

         Section 7.08 ERISA.

                  (a) The Borrower and each ERISA Affiliate have complied in all
material respects with ERISA and, where applicable, the Code regarding each
Plan.

                  (b) Each Plan and each Welfare Plan is, and has been,
maintained in substantial compliance with ERISA and, where applicable, the Code.

                  (c) No act, omission or transaction has occurred which could
reasonably be expected to result in imposition on the Borrower or any ERISA
Affiliate (whether directly or indirectly) of (i) either a civil penalty
assessed pursuant to Section 502(c), (i), (l) or (m) of ERISA or a tax imposed
pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary
duty liability damages under Section 409 of ERISA.

                  (d) No Plan (other than a defined contribution plan) or any
trust created under any such Plan has been terminated within the preceding six
calendar years. No liability to the PBGC (other than for the payment of current
premiums which are not past due) by the Borrower or any ERISA Affiliate has been
or is expected by the Borrower or any ERISA Affiliate to be incurred with
respect to any Plan. No ERISA Event with respect to any Plan (other than a
Multiemployer Plan) has occurred.

                  (e) Full payment when due has been made of all amounts which
the Borrower or any ERISA Affiliate is required under the terms of each Plan and
each Welfare Plan or applicable law to have paid as contributions to such Plan
or Welfare Plan, and no accumulated funding deficiency (as defined in Section
302 of ERISA and Section 412 of the Code), whether or not waived, exists with
respect to any Plan.

                  (f) The actuarial present value of the benefit liabilities
under each Plan which is subject to Title IV of ERISA does not, as of the end of
the Borrower's most recently ended fiscal year, exceed the current value of the
assets (computed on a plan termination basis in accordance with Title IV of
ERISA) of such Plan allocable to such benefit liabilities. The term "actuarial
present value of the benefit liabilities" shall have the meaning specified in
Section 4041 of ERISA.

                  (g) None of the Borrower or any ERISA Affiliate sponsors,
maintains, or contributes to an employee welfare benefit plan, as defined in
Section 3(1) of ERISA, including, without limitation, any such plan maintained
to provide benefits to former employees of such entities, that may not be
terminated by the Borrower or any ERISA Affiliate in its sole discretion at any
time without any liability that could reasonably be expected to have a Material
Adverse Affect.

                  (h) None of the Borrower or any ERISA Affiliate sponsors,
maintains or contributes to, or has at any time in the preceding six calendar
years, sponsored, maintained or contributed to, any Multiemployer Plan.



                                      -52-
<PAGE>

                  (i) None of the Borrower or any ERISA Affiliate is required to
provide security under Section 401(a)(29) of the Code due to a Plan amendment
that results in an increase in current liabilities of the Plan.

         Section 7.09 Taxes. Each of the Borrower and its Subsidiaries has filed
or obtained extensions for filing of all United States Federal income tax
returns and all other tax returns which are required to be filed by them and
have paid all material taxes shown to be due pursuant to such returns or
pursuant to any assessment received by the Borrower or any Subsidiary, except
for any taxes which are being contested in good faith by appropriate proceedings
and for which adequate reserves are being maintained in accordance with GAAP.
The charges, accruals and reserves on the books of the Borrower and its
Subsidiaries in respect of taxes and other governmental charges are, in the
opinion of the Borrower, adequate. No tax lien has been filed and, to the
knowledge of the Borrower, no claim is being asserted with respect to any such
tax, fee or other charge.

         Section 7.10 Titles, etc. Except as set forth in Schedule 7.10:

                  (a) Each of the Borrower and its Subsidiaries has good and
defensible title to its material (individually or in the aggregate) Properties,
free and clear of all Liens, except Liens permitted by Section 9.02. Material
Property held by the Borrower or its Subsidiaries under leases or similar
arrangements are listed in item 2 of Schedule 7.10.

                  (b) All material leases and agreements necessary for the
conduct of the business of the Borrower and its Subsidiaries are valid and
subsisting, in full force and effect and there exists no default or event or
circumstance which with the giving of notice or the passage of time or both
would give rise to a default under any such lease or leases, which could
reasonably be expected to result in a Material Adverse Effect.

                  (c) The rights, Properties and other assets presently owned,
leased or licensed by the Borrower and its Subsidiaries including, without
limitation, all easements and rights of way, include all rights, Properties and
other assets necessary to permit the Borrower and its Subsidiaries to conduct
their business in all material respects in the same manner as its business has

statement, exhibit, certificate, document or report, taken as a whole, furnished
to the Administrative Agent and the Lenders (or any of them) by the Borrower or
any Subsidiary in connection with the negotiation of this Agreement contained
any material misstatement of fact or omitted to state a material fact or any
fact necessary to make the statement contained therein not materially misleading
in the light of the circumstances in which made and with respect to the Borrower
and its Subsidiaries taken as a whole. To the best knowledge of the Borrower
after due inquiry, as of the Closing Date there is no fact peculiar to the
Borrower or any Subsidiary which has a Material Adverse Effect or in the future

         Section 7.16 Defaults. Neither the Borrower nor any Subsidiary is in

of any applicable grace period or the giving of notice, or both, would
constitute a default under any material agreement or instrument to which the

is bound which default would have a Material Adverse Effect. No Default
hereunder has occurred and is continuing.

         Section 7.17 Environmental Matters. Except as would not reasonably be
expected to have a Material Adverse Effect (or with respect to clauses (c) and
(d) below, where the failure to take such actions would not reasonably be

or threatened action, suit, investigation, inquiry or proceeding by or before
any court or Governmental Authority or to any remedial obligations under
Environmental Laws;

                  (c) All notices, permits, licenses or similar authorizations,
if any, required to be obtained or filed in connection with the operation or use

                                      -54-
<PAGE>

Borrower and each Subsidiary, including without limitation past or present
treatment, storage, disposal or release of a hazardous substance or solid waste
into the environment, are set forth on Schedule 7.17 and have been duly obtained

environment, and, to the best knowledge of the Borrower, all such transport
carriers and treatment and disposal facilities have been and are operating in
compliance with Environmental Laws and so as not to pose an imminent and
substantial endangerment to public health or welfare or the environment, and are
not the subject of any existing, pending or threatened action, investigation or
inquiry by any Governmental Authority in connection with any Environmental Laws;

                  (e) The Borrower has taken all steps reasonably necessary to
determine and based on such steps and due inquiry has no reason to believe that
any hazardous substances, solid waste, or oil and gas exploration and production
wastes, have been disposed of or otherwise released or that there has been any
threatened release of any hazardous substances on or to any Property of the
Borrower or any Subsidiary, in each case except in compliance with Environmental
Laws and so as not to pose an imminent and substantial endangerment to public
health or welfare or the environment;

                  (f) To the extent applicable, all Property of the Borrower and
each Subsidiary currently satisfies all design, operation, and equipment
requirements imposed by the Environmental Laws applicable to the Borrower and
its Subsidiaries during the term of this Agreement, and the Borrower does not
have any reason to believe that such Property, to the extent subject to
Environmental Laws, will not be able to maintain compliance with Environmental
Laws requirements during the term of this Agreement;

                                      -55-
<PAGE>

applicable Environmental Laws, any hazardous substances that have been generated
on such real Property have been transported offsite only by carriers having an
identification number issued by the EPA, treated or disposed of only by
treatment or disposal facilities maintaining valid permits as required under
applicable Environmental Laws, which transporters and facilities, to the best of
the Borrower's knowledge, have been and are operating in material compliance
with such permits and applicable Environmental Laws.

         Section 7.18 Compliance with the Law. Neither the Borrower nor any
Subsidiary has violated any Governmental Requirement or failed to obtain any
license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the conduct of its business, which
violation or failure could reasonably be expected to have (in the event such
violation or failure were asserted by any Person through appropriate action) a
Material Adverse Effect.

         Section 7.19 Insurance. Schedule 7.19 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation and other forms of insurance owned or held by the
Borrower and each Subsidiary as of the Closing Date. As of such date, all such
policies are in full force and effect, all premiums with respect thereto
covering all periods up to and including the date of the closing have been paid,
and no notice of cancellation or termination has been received with respect to
any such policy. Such policies are sufficient for compliance with all
requirements of law and of all agreements to which the Borrower or any
Subsidiary is a party; are valid, outstanding and enforceable policies; provide
adequate insurance coverage in at least such amounts and against at least such
risks (but including in any event public liability) as are usually insured
against in the same general area by companies engaged in the same or a similar
business for the assets and operations of the Borrower and each Subsidiary; will
remain in full force and effect through the respective dates set forth in
Schedule 7.19 without the payment of additional premiums; and will not in any
way be affected by, or terminate or lapse by reason of, the transactions
contemplated by this Agreement. Schedule 7.19 identifies all material risks, if
any, as to which the Borrower and its Subsidiaries and their respective Board of
Directors or officers have designated themselves as being self insured as of the
Closing Date. Neither the Borrower nor any Subsidiary has been unable to obtain
any insurance with respect to its assets or operations, nor has its coverage
been limited below usual and customary policy limits, by an insurance carrier to
which it has applied for any such insurance or with which it has carried
insurance during the last three years.

         Section 7.20 Restriction on Liens. Neither the Borrower nor any of its
Subsidiaries is a party to any agreement or arrangement (other than this
Agreement and the Security Instruments, and any contracts or agreements in
respect of liens permitted under Section 9.02), or subject to any order,
judgment, writ or decree, which either restricts or purports to restrict its
ability to grant Liens to other Persons on or in respect of their respective
assets or Properties.

         Section 7.21 Material Agreements. Set forth on Schedule 7.21 hereto is
a complete and correct list of all material agreements, indentures, purchase
agreements, obligations in respect of letters of credit, guarantees, joint
venture agreements, and other instruments in effect or to be in effect as of the
Closing Date providing for, evidencing, securing or otherwise relating to any
Debt of the Borrower or any of its Subsidiaries, and all material obligations of
the Borrower or any of its Subsidiaries to issuers of material surety or appeal
bonds issued for account of the



                                      -56-
<PAGE>

Borrower or any such Subsidiary, and subject to Schedule 7.21 such list
correctly sets forth the names of the debtor and creditor with respect to the
Debt obligations outstanding or to be outstanding and the Property subject to
any Lien securing such Debt obligation. The Borrower has heretofore delivered to
the Administrative Agent and the Lenders a complete and correct copy of all such
material credit agreements, indentures, purchase agreements, contracts, letters
of credit, guarantees, joint venture agreements, or other instruments, including
any modifications or supplements thereto, as in effect on the Closing Date.

such changes in such principles with which the independent public accountants

Consolidated Subsidiaries in accordance with GAAP, as at the end of, and for,
such period (subject to normal year-end audit adjustments).

                  (c) Annual Projections. As soon as available and in any event

stockholders generally and each regular or periodic report and any registration

connection therewith from any securities exchange or the SEC; provided, however,
that the requirement to deliver the Borrower's quarterly reports (Form 10-Q) and

writing to keep all such information confidential on the same terms as agreed to
between the Borrower and such Person.

                  (j) Other Matters. From time to time such other information
regarding the business, affairs or financial condition of the Borrower or any
Subsidiary (including, without limitation, any Plan or Multiemployer Plan and

or the Administrative Agent may reasonably request.

The Borrower will furnish to the Administrative Agent, at the time it furnishes
each set of financial statements pursuant to clause (a) or (b) above, a

in each case proceedings or other matters which would not reasonably be expected
to have a Material Adverse Effect, provided, however Borrower need not give
notice of any proceedings as to which it is not a party and that affects the
Borrower's and its Subsidiaries' industry generally. The Borrower will, and will
cause each of its Subsidiaries to, promptly notify the Administrative Agent and
each of the Lenders of any claim not fully covered by insurance (subject to
normal deductibles), judgment, Lien or other encumbrance resulting from any
litigation or other proceeding and affecting any Property of the Borrower or any

Material Adverse Effect; file all federal income tax returns and pay all amounts
shown thereon to be due, and pay and discharge all other material taxes,

business and affairs with its officers, all to the extent reasonably requested

insurance proceeds are not used by the Borrower or its Subsidiary for
restoration, repair or replacement of the damaged Property or (iii) upon

so as to pose an imminent and substantial endangerment to public health or
welfare or the environment.

                  (b) Notice of Action. The Borrower will promptly notify the
Administrative Agent and the Lenders in writing of any threatened action,
investigation or inquiry by any Governmental Authority of which the Borrower has
knowledge in connection with any Environmental Laws, excluding action in respect
of permit applications in the ordinary course of business and routine testing
and corrective action.

                  (c) Future Acquisitions. The Borrower will and will cause each
Subsidiary to provide environmental audits and tests as are usual and customary
to be obtained for Properties of similar use and purpose as reasonably requested
by the Administrative Agent and the Majority Lenders (or as otherwise required
to be obtained by the Administrative Agent or the Majority Lenders by any
Governmental Authority) in connection with any future acquisitions of real
Properties.

         Section 8.05 Further Assurances. Upon the request of the Administrative
Agent, the Borrower will and will cause each Subsidiary to cure promptly any
defects in the creation and issuance of the Obligations and the execution and

and the other Loan Documents. Without limiting the foregoing, upon the creation
or acquisition of any Subsidiary, the Borrower shall (a) provide written notice
of such event to the Administrative Agent within five Business Days following
the date the Borrower has knowledge thereof, and (b) cause each such Subsidiary
to execute and deliver a Guaranty Agreement (or written joinder to existing

thereof. If any Subsidiary is created or acquired after the date hereof, the
Borrower shall execute and deliver to the Administrative Agent (i) an amendment
to this Agreement to amend Schedule 7.14 (which only needs the signature of the
Administrative Agent to be effective if the only change is the addition of the
new Subsidiary) and (ii) any other documents, instruments, or agreements
required by the Administrative Agent. This Section 8.08 shall not be construed
as permitting the creation or acquisition of any Subsidiary not otherwise
permitted by Section 9.19.

                                   ARTICLE XI

                            THE ADMINISTRATIVE AGENT

         Section 11.01 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
hereunder and under the Security Instruments with such powers as are
specifically delegated to the Administrative Agent by the terms of this
Agreement and the Security Instruments, together with such other powers as are
reasonably incidental thereto. The Administrative Agent (which term as used in
this sentence



                                      -71-
<PAGE>

and in Section 11.05 and the first sentence of Section 11.06 shall include
reference to its Affiliates and its and its Affiliates' officers, directors,
employees, attorneys, accountants, experts and agents): (i) shall have no duties
or responsibilities except those expressly set forth in the Loan Documents, and
shall not by reason of the Loan Documents be a trustee or fiduciary for any
Lender; (ii) makes no representation or warranty to any Lender and shall not be
responsible to the Lenders for any recitals, statements, representations or
warranties contained in this Agreement, or in any certificate or other document
referred to or provided for in, or received by any of them under, this
Agreement, or for the value, validity, effectiveness, genuineness, execution,
effectiveness, legality, enforceability or sufficiency of this Agreement, any
Note or any other document referred to or provided for herein or for any failure
by the Borrower or any other Person (other than the Administrative Agent) to
perform any of its obligations hereunder or thereunder or for the existence,
value, perfection or priority of any collateral security or the financial or
other condition of the Borrower, its Subsidiaries or any other obligor or
guarantor; (iii) except pursuant to Section 11.07 shall not be required to
initiate or conduct any litigation or collection proceedings hereunder; and (iv)
shall not be responsible for any action taken or omitted to be taken by it
hereunder or under any other document or instrument referred to or provided for
herein or in connection herewith including its own ordinary negligence, except
for its own gross negligence or willful misconduct. The Administrative Agent may
employ agents, accountants, attorneys and experts and shall not be responsible
for the negligence or misconduct of any such agents, accountants, attorneys or
experts selected by it in good faith or any action taken or omitted to be taken
in good faith by it in accordance with the advice of such agents, accountants,
attorneys or experts. The Administrative Agent may deem and treat the payee of
any Note as the holder thereof for all purposes hereof unless and until a
written notice of the assignment or transfer thereof permitted hereunder shall
have been filed with the Administrative Agent. The Administrative Agent is
authorized to release any collateral that is permitted to be sold or released
pursuant to the terms of the Loan Documents.

         Section 11.02 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely upon any certification, notice or other
communication (including any thereof by telephone, telex, telecopier, telegram
or cable) believed by it to be genuine and correct and to have been signed or
sent by or on behalf of the proper Person or Persons, and upon advice and
statements of legal counsel, independent accountants and other experts selected
by the Administrative Agent.

         Section 11.03 Defaults. The Administrative Agent shall not be deemed to
have knowledge of the occurrence of a Default (other than the non-payment of
principal of or interest on Loans or of fees or failure to reimburse for Letter
of Credit drawings or Direct Pay Letter of Credit drawings) unless the
Administrative Agent has received notice from a Lender or the Borrower
specifying such Default and stating that such notice is a "Notice of Default."
In the event that the Administrative Agent receives such a notice of the
occurrence of a Default, the Administrative Agent shall give prompt notice
thereof to the Lenders. In the event of a payment Default, the Administrative
Agent shall give each Lender prompt notice of each such payment Default.

         Section 11.04 Rights as a Lender. With respect to its Commitments and
the Loans made by it and its participation in the issuance of Letters of Credit
or the Direct Pay Letter of Credit, Wells Fargo (and any successor acting as
Administrative Agent) in its capacity as a Lender



                                      -72-
<PAGE>

hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as the Administrative
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include the Administrative Agent in its individual capacity. Wells
Fargo (and any successor acting as Administrative Agent) and its Affiliates may
(without having to account therefor to any Lender) accept deposits from, lend
money to and generally engage in any kind of banking, trust or other business
with the Borrower (and any of its Affiliates) as if it were not acting as the
Administrative Agent, and Wells Fargo and its Affiliates may accept fees and
other consideration from the Borrower for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

         Section 11.05 Indemnification. The Lenders agree to indemnify the
Administrative Agent and the Issuing Bank ratably in accordance with their
Percentage Shares for the Indemnity Matters as described in Section 13.03 to the
extent not indemnified or reimbursed by the Borrower under Section 13.03, but
without limiting the obligations of the Borrower under said Section 13.03 and
for any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind and
nature whatsoever which may be imposed on, incurred by or asserted against the
Administrative Agent or the Issuing Bank in any way relating to or arising out
of: (i) this Agreement, the Security Instruments or any other documents
contemplated by or referred to herein or the transactions contemplated hereby,
but excluding, unless a Default has occurred and is continuing, normal
administrative costs and expenses incident to the performance of its agency
duties hereunder or (ii) the enforcement of any of the terms of this Agreement,
any Security Instrument or of any such other documents; whether or not any of
the foregoing specified in this Section 11.05 arises from the sole or concurrent
negligence of the Administrative Agent or the Issuing Bank, provided that no
Lender shall be liable for any of the foregoing to the extent they arise from
the gross negligence or willful misconduct of the Administrative Agent.

         Section 11.06 Non-Reliance on Administrative Agent and other Lenders.
Each Lender acknowledges and agrees that it has, independently and without
reliance on the Administrative Agent or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis of the Borrower and its decision to enter into this Agreement, and that
it will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement. The Administrative Agent shall
not be required to keep itself informed as to the performance or observance by
the Borrower of this Agreement, the Notes, the Security Instruments or any other
document referred to or provided for herein or to inspect the properties or
books of the Borrower. Except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Borrower (or any
of its Affiliates) which may come into the possession of the Administrative
Agent or any of its Affiliates. In this regard, each Lender acknowledges that
Winstead Sechrest & Minick P.C. is acting in this transaction as special counsel
to the Administrative Agent only, except to the extent otherwise expressly
stated in any legal opinion or any Loan Document. Each Lender



                                      -73-
<PAGE>

will consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein.

         Section 11.07 Action by Administrative Agent. Except for action or
other matters expressly required of the Administrative Agent hereunder, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall (i) receive written instructions from
the Majority Lenders (or all of the Lenders as expressly required by Section
13.04) specifying the action to be taken, and (ii) be indemnified to its
satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action. The
instructions of the Majority Lenders (or all of the Lenders as expressly
required by Section 13.04) and any action taken or failure to act pursuant
thereto by the Administrative Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, the Administrative Agent shall take such
action with respect to such Default as shall be directed by the Majority Lenders
(or all of the Lenders as required by Section 13.04) in the written instructions
(with indemnities) described in this Section 11.07, provided that, unless and
until the Administrative Agent shall have received such directions, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interests of the Lenders. In no event, however, shall the
Administrative Agent be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement and the Security Instruments or applicable law.

         Section 11.08 Resignation or Removal of Administrative Agent. Subject
to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Borrower, and the Administrative Agent may be
removed at any time with or without cause by the Majority Lenders. Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Administrative Agent with the consent of the Borrower, which consent
shall not be unreasonably withheld. If no successor Administrative Agent shall
have been so appointed by the Majority Lenders in accordance with the foregoing
provisions, and shall have accepted such appointment within 30 days after the
retiring Administrative Agent's giving of notice of resignation or the Majority
Lenders' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent. Upon the acceptance of such appointment 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 any
retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Article XI and Section 13.03 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.

         Section 11.09 Issuing Bank as Agent. The Administrative Agent hereby
irrevocably appoints and authorizes the Issuing Bank to act as its agent (for
the benefit of itself, the Administrative Agent and the other Lenders) under the
Security Instruments and the other Related Documents with such other powers as
are reasonably incidental thereto for purposes of holding maintaining, or taking
any action with respect to the collateral securing the Obligations,



                                      -74-
<PAGE>

including without limitation, the Direct Pay Letter of Credit. The Issuing Bank
is authorized to release any collateral that is permitted to be sold or released
pursuant to the terms of the Related Documents.

         Section 11.10 Collateral and Guaranty Matters. The Lenders irrevocably
authorize the Administrative Agent, at its option and in its discretion:

                  (a) to release any Lien on any Property granted to or held by
the Administrative Agent under any Loan Document (i) upon termination of the
Commitments and payment in full of all Obligations (other than contingent
indemnification obligations) and the expiration or termination of all Letters of
Credit and the Direct Pay Letter of Credit, (ii) that is sold or to be sold as
part of or in connection with any sale permitted hereunder or under any other
Loan Document, or (iii) subject to Section 13.04, if approved, authorized or
ratified in writing by the Majority Lenders; and

                  (b) to release any Guarantor from its obligations under the
Guaranty Agreement if such Person ceases to be a Subsidiary as a result of a
transaction permitted hereunder.

         Upon request by the Administrative Agent at any time, the Majority
Lenders will confirm in writing the Administrative Agent's authority to release
its interest in particular types or items of property, or to release any
Guarantor from its obligations under the Guaranty pursuant to this Section
11.10.

                                  ARTICLE XII

                                    SECURITY

         The Obligations shall be secured by (i) a perfected first priority
security interest and Lien (subject only to Liens permitted under Section 9.02
entitled to priority under applicable law or under Section 9.02) in all of the
assets (except that perfection of Liens in motor vehicles and granting and
perfection of Liens in any real Property not currently held as collateral
(provided that with respect to any such real Property subject to any prohibition
against transfer or the granting of a Lien, Borrower will, or will cause any
Subsidiary to, diligently pursue consent to grant a Lien and permit a transfer
of such Property in foreclosure, and upon the receipt of such consent a Lien
shall be granted and perfected) shall be completed upon 30 days request therefor
by the Administrative Agent acting on behalf of the Majority Lenders or the
Majority Lenders) of the Borrower and its Subsidiaries, whether now owned or
hereafter acquired or existing, pursuant to the terms of the Security
Instruments to which they are parties, and (ii) a pledge of all of the stock of
or other equity interests in the Borrower and each Subsidiary pursuant to the
terms of the Security Instruments. The Borrower shall, and shall cause its
Subsidiaries to, (i) perfect the security interest in motor vehicles as required
above and (ii) pledge such real Property to the Secured Parties as they may
request upon written notice from the Administrative Agent, the form and
substance of all Security Instruments to be reasonably satisfactory to the
Administrative Agent.

                                  MISCELLANEOUS

         Section 13.01 Waiver. No failure on the part of the Administrative
Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under any of the Loan
Documents shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.

         Section 13.02 Notices. All notices and other communications provided

Section 13.03(a)(iii) in respect of any Property for any occurrence arising from
the acts or omissions of the Administrative Agent or any Lender during the
period after which such Person, its successors or assigns shall have obtained
possession of such Property (whether by foreclosure or deed in lieu of
foreclosure, as mortgagee-in-possession or otherwise).

                  (b) No Indemnified Party may settle any claim to be
indemnified without the consent of the indemnitor, such consent not to be
unreasonably withheld; provided, that the indemnitor may not reasonably withhold
consent to any settlement that an Indemnified Party proposes, if the indemnitor
does not have the financial ability to pay all its obligations outstanding and
asserted against the indemnitor at that time, including the maximum potential
claims against the Indemnified Party to be indemnified pursuant to this Section
13.03.

                  (c) In the case of any indemnification hereunder, the
Administrative Agent or Lender, as appropriate shall give notice to the Borrower
of any such claim or demand being made against the Indemnified Party and the
Borrower shall have the non-exclusive right to join in the defense against any
such claim or demand provided that if the Borrower provides a defense, the
Indemnified Party shall bear its own cost of defense unless there is a conflict

act or an omission, including without limitation, all types of negligent conduct
identified in the restatement (second) of torts of one or more of the
Indemnified Parties or by reason of strict liability imposed without fault on
any one or more of the Indemnified Parties. To the extent that an Indemnified
Party is found to have committed an act of gross negligence or willful
misconduct, this contractual obligation of indemnification shall continue but

reason of events other than the gross negligence or willful misconduct of the
Indemnified Party.

                  (e) The Borrower's obligations under this Section 13.03 shall

Security Instrument to which the Borrower is a party may be amended, modified or
waived with the Borrower's and the Majority Lenders' prior written consent;
provided that (i) no amendment, modification or waiver which extends the final
maturity of the Loans, increases the Aggregate Revolving Credit Commitments,
forgives the principal amount of any Loans outstanding under this Agreement,
releases any guarantor of the Obligations or releases all or substantially all
of the collateral, reduces the interest rate applicable to the Loans or the fees
payable to the Lenders generally, amends, modifies or waives Section 2.03(a),
this Section 13.04 or Section 13.06(a) or modifies the definition of "Majority
Lenders" shall be effective without consent of all Lenders;

Commitment or the Direct Pay Letter of Credit Commitment of any Lender or
forgives any Obligations (other than Loans) of any Lender shall be effective
without the consent of such Lender; (iii) no amendment, modification or waiver
which modifies the rights, duties or obligations of the Administrative Agent
shall be effective without the consent of the Administrative Agent; and (iv) no
amendment, modification or waiver which modifies the rights, duties or
obligations of the Issuing Bank shall be effective without the consent of the
Issuing Bank. Notwithstanding anything to the contrary contained herein or in
any other Loan Document, the Administrative Agent is hereby irrevocably
authorized (without the consent of or requirement of notice to any Lender except
as expressly required by this Section 13.04) to take any action requested by the
Borrower having the effect of releasing any collateral to the extent necessary
to permit consummation of any transaction not prohibited by any Loan Document or
that has been consented to in accordance with this Section 13.04.

         Section 13.05 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

         Section 13.06 Assignments and Participations.

                  (a) Neither the Borrower nor Waste Corporation Texas may
assign its rights or obligations hereunder or under the Notes, any Letters of
Credit or the Direct Pay Letter of Credit without the prior consent of all of
the Lenders and the Administrative Agent.

                  (b) Any Lender may, upon the written consent of the
Administrative Agent and, if no Event of Default has occurred and is continuing,
the Borrower (which consent will not be unreasonably withheld), assign to one or
more Eligible Assignees all or a portion of its rights and obligations under
this Agreement pursuant to an Assignment Agreement substantially in the form of
Exhibit D (an "Assignment"); provided, however, that (i) any such assignment
shall assign proportionate amounts (if less than all) in each of such assignors
Loans and Commitments, (ii) any such assignment shall be in the amount of at
least $3,000,000 or such lesser amount to which the Borrower has consented and
(iii) the assignee or assignor shall pay to the Administrative Agent a
processing and recordation fee of $5,000 for each assignment. Any such
assignment will become effective as of the date provided therein upon the
execution and delivery to the Administrative Agent of the Assignment and the
consent of the Administrative Agent and, if applicable, the Borrower. Promptly
after receipt of an executed Assignment, the Administrative Agent shall send to
the Borrower a copy of such executed Assignment. Upon receipt of such executed
Assignment, the Borrower, will, at its own expense, execute and deliver new
Notes to the assignor and/or assignee, as appropriate, in accordance with their
respective interests as they appear. Upon the effectiveness of any assignment
pursuant to this Section 13.06(b), the assignee will become a "Lender," if not
already a "Lender," for all purposes of this Agreement and the Security
Instruments. The assignor shall be relieved of its obligations hereunder from
and after the effective date thereof to the extent of such assignment (and if
the assigning Lender no longer holds any rights or obligations under this
Agreement, such assigning Lender shall cease to be a "Lender" hereunder except
that its rights under Sections 4.06, 5.01, 5.05 and 13.03 shall not be
affected). The Administrative Agent will prepare on the last Business Day of
each month during which an assignment has become effective pursuant to this



                                      -79-
<PAGE>

Section 13.06(b), a new Annex I giving effect to all such assignments effected
during such month, and will promptly provide the same to the Borrower and each
of the Lenders.

                  (c) Each Lender may transfer, grant or assign participations
in all or any part of such Lender's interests hereunder pursuant to this Section
13.06(c) to any Person, provided that: (i) such Lender shall remain a "Lender"
for all purposes of this Agreement and the transferee of such participation
shall not constitute a "Lender" hereunder; and (ii) no participant under any
such participation shall have rights to approve any amendment to or waiver of
any of the Loan Documents except to the extent such amendment or waiver would
(x) forgive any principal owing on any Obligations or extend the final maturity
of the Loans in which such participant is participating, (y) reduce the interest
rate (other than as a result of waiving the applicability of any post-default
increases in interest rates) or fees applicable to any of the Commitments or
Loans or Letters of Credit or Direct Pay Letter of Credit in which such
participant is participating, or postpone the payment of any thereof, or (z)
release any guarantor of the Obligations or release all or substantially all of
the collateral (except as provided in the Loan Documents) supporting any of the
Commitments or Loans or Letters of Credit or Direct Pay Letter of Credit in
which such participant is participating. In the case of any such participation,
the participant shall not have any rights under this Agreement or any of the
Security Instruments (the participant's rights against the granting Lender in
respect of such participation to be those set forth in the agreement with such
Lender creating such participation), and all amounts payable by the Borrower
hereunder shall be determined as if such Lender had not sold such participation,
provided that such participant shall be entitled to receive additional amounts
under Article V on the same basis as if it were a Lender (but only to the extent
that such additional amounts paid to any such participant does not require the
Borrower to make payments in respect of the Loans of any Lender in excess of
what such Lender would have received had such loans not been participated) and
be indemnified under Section 13.03 as if it were a Lender. In addition, each
agreement creating any participation must include an agreement by the
participant to be bound by the provisions of Section 13.15 for the benefit of
the Borrower.

                  (d) The Lenders may furnish any information concerning the
Borrower in the possession of the Lenders from time to time to assignees and
participants (including prospective assignees and participants); provided that,
such Persons agree to be bound by the provisions of Section 13.15 for the
benefit of the Borrower.

                  (e) Notwithstanding anything in this Section 13.06 to the
contrary, any Lender may assign and pledge all or any of its Notes to any
Federal Reserve Bank. No such assignment and/or pledge shall release the
assigning and/or pledging Lender from its obligations hereunder.

                  (f) Notwithstanding any other provisions of this Section
13.06, no transfer or assignment of the interests or obligations of any Lender
or any grant of participations therein shall be permitted if such transfer,
assignment or grant would require the Borrower (i) to file a registration
statement with the SEC (ii) to qualify the Loans under the "Blue Sky" laws of
any state, or (iii) to contravene the prohibited transactions restrictions of
Sections 4975 of the code or Sections 406 or 407 of ERISA.

         Section 13.07 Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents or the Letters of Credit or
Direct Pay Letter of Credit, or the



                                      -80-
<PAGE>

Letter of Credit Agreements shall, for any reason, be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision of the Notes, this Agreement or any other
Loan Document.

         Section 13.08 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart. Facsimiles of signatures shall be binding and
effective as originals.

         Section 13.09 References; Use of Word "Including". The words "herein,"
"hereof," "hereunder" and other words of similar import when used in this
Agreement refer to this Agreement as a whole, and not to any particular article,
section or subsection. Any reference herein to a Section or Article shall be
deemed to refer to the applicable Section or Article of this Agreement unless
otherwise stated herein. Any reference herein to an exhibit, schedule, or other
attachment shall be deemed to refer to the applicable exhibit, schedule, or
other attachment attached hereto unless otherwise stated herein. The word
"including", "includes" and words of similar import means "including, without
limitation".

         Section 13.10 Survival. The obligations of the parties under Section
4.06, Article V, and Sections 11.05 and 13.03 shall survive the repayment of the
Loans and the termination of the Commitments. To the extent that any payments on
the Obligations or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Obligations so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Administrative Agent's and the Lenders' Liens, security
interests, rights, powers and remedies under this Agreement and each Security
Instrument effective immediately prior thereto shall continue in full force and
effect. In such event, each such Security Instrument shall be automatically
reinstated and the Borrower shall take such action as may be reasonably
requested by the Administrative Agent and the Lenders to effect such
reinstatement.

         Section 13.11 Captions. Captions and section headings appearing herein
are included solely for convenience of reference and are not intended to affect
the interpretation of any provision of this Agreement.

         Section 13.12 No Oral Agreements. The Loan Documents embody the entire
agreement and understanding between the parties and supersede all other
agreements and understandings between such parties relating to the subject
matter hereof and thereof. The 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 13.13 Governing Law; Submission to Jurisdiction.

                  (a) This Agreement and the Notes shall be governed by, and
construed in accordance with, the laws of the State of Texas, except to the
extent that United States federal law preempts Texas law and permits any Lender
to contract for, charge or receive interest at a



                                      -81-
<PAGE>

rate greater than that permitted by Texas law or to charge the rate allowed by
the laws of the state where such Lender is located, in which event Federal Law
shall control. Chapter 346 of the Texas Finance Code (which regulates certain
revolving credit loan accounts and revolving tri-party accounts) shall not apply
to this Agreement or the Notes.

                  (b) Any legal action or proceeding with respect to the Loan
Documents shall be brought in the courts of the State of Texas or of the United
States of America for the Southern District of Texas, Houston Division, and, by
execution and delivery of this Agreement, the Borrower hereby accepts for itself
and (to the extent permitted by law) in respect of its Property, generally and
unconditionally, the jurisdiction of the aforesaid courts. To the extent
permitted by law, the Borrower hereby irrevocably waives any objection,
including, without limitation, any objection to the laying of venue or based on
the grounds of forum non conveniens, which it may now or hereafter have to the
bringing of any such action or proceeding in such respective jurisdictions. This
submission to jurisdiction is non-exclusive and does not preclude the
Administrative Agent or any Lender from obtaining jurisdiction over the Borrower
in any court otherwise having jurisdiction.

                  (c) The Borrower hereby irrevocably consents to the service of
process of any of the aforementioned courts in any such action or proceeding by
the mailing of copies thereof by registered or certified mail, postage prepaid,
to the Borrower at its said address, such service to become effective 30 days
after such mailing. Nothing herein shall affect the right of the Administrative
Agent, any Lender or any holder of a Note to serve process in any other manner
permitted by law or to commence legal proceedings or otherwise proceed against
the Borrower or its Properties in any other jurisdiction.

                  (d) Each of the Borrower, the Administrative Agent and each
Lender hereby (i) irrevocably and unconditionally waives, to the fullest extent
permitted by law, trial by jury in any legal action or proceeding relating to
this Agreement or any Loan Document and for any counterclaim therein; (ii)
irrevocably waives, to the maximum extent not prohibited by law, any right it
may have to claim or recover in any such litigation any special, exemplary,
punitive or consequential damages, or damages other than, or in addition to,
actual damages, together with court costs, attorney fees and other costs of
litigating or contesting such matter; (iii) certifies that no party hereto nor
any representative, agent or counsel for any party hereto has represented,
expressly or otherwise, or implied that such party would not, in the event of
litigation, seek to enforce the foregoing waivers, and (iv) acknowledges that it
has been induced to enter into this Credit Agreement and the other Loan
Documents and the transactions contemplated hereby and thereby by, among other
things, the mutual waivers and certifications contained in this Section 13.13.

         Section 13.14 Interest. It is the intention of the parties hereto to
conform strictly to applicable usury laws. Accordingly, if the transactions
contemplated hereby would be usurious as to any Lender, the Administrative Agent
or an Issuing Bank (for purposes of this Section 13.14 referred to individually
as a "Lender Party" and collectively as the "Lender Parties") under laws
applicable to it or to its Loans or other extensions of credit hereunder or
under any other Loan Document (including the laws of the United States of
America and the State of Texas or any other jurisdiction whose laws may be
mandatorily applicable notwithstanding the other provisions of this Agreement),
then, in that event, notwithstanding



                                      -82-
<PAGE>

anything to the contrary in any of the Loan Documents or any other agreement
entered into in connection with or as security for the Notes, it is agreed as
follows: (a) the aggregate of all consideration which constitutes interest under
law applicable to any Lender Party or to its Loans or other extensions of credit
hereunder or under any other Loan Document or other agreement that is contracted
for, taken, reserved, charged or received by such Lender Party under any of the
Loan Documents or other agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by such Lender Party on the principal amount
of the Obligations (or, to the extent that the principal amount of the
Obligations shall have been or would thereby be paid in full, refunded by such
Lender to the Borrower); (b) in the event that the maturity of the Notes is
accelerated by reason of an election of the holder thereof resulting from any
Event of Default under this Agreement or otherwise, or in the event of any
required or permitted prepayment, or if any transaction contemplated by any Loan
Document would otherwise be usurious under any applicable law, then such
consideration that constitutes interest under law applicable to any Lender Party
or to its Loans or other extensions of credit hereunder or under any other Loan
Document may never include more than the maximum amount allowed by such
applicable law, and excess interest, if any, provided for in this Agreement or
otherwise shall be canceled automatically as of the date of such acceleration or
prepayment or other event or circumstance and, if theretofore paid, shall be
credited by such Lender Party on the principal amount of the Obligations (or, to
the extent that the principal amount of the Obligations shall have been or would
thereby be paid in full, refunded by such Lender to the Borrower) and (c) in no
event shall any provision of any Loan Document require any unearned interest.
All sums paid or agreed to be paid to any Lender Party for the use, forbearance
or detention of sums due hereunder or under any other Loan Document shall, to
the extent permitted by law applicable to such Lender Party or to its Loans or
other extensions of credit hereunder or under any other Loan Document, be
amortized, prorated, allocated and spread throughout the full term of the Loans
evidenced by the Notes until payment in full so that the rate or amount of
interest on account of any Loans hereunder or other extension of credit under
any of the Loan Documents does not exceed the maximum amount allowed by such
applicable law. If at any time and from time to time (i) the amount of interest
payable to any Lender Party on any date shall be computed at the Highest Lawful
Rate applicable to such Lender or to its Loans or other extensions of credit
hereunder pursuant to this Section 13.14 and (ii) in respect of any subsequent
interest computation period the amount of interest otherwise payable to such
Lender Party would be less than the amount of interest payable to such Lender
computed at the Highest Lawful Rate applicable to such Lender Party or to its
Loans or other extensions of credit hereunder, then, to the extent permitted by
law, the amount of interest payable to such Lender in respect of such subsequent
interest computation period shall continue to be computed at the Highest Lawful
Rate applicable to such Lender Payable until the total amount of interest
payable to such Lender Party shall equal the total amount of interest which
would have been payable to such Lender Party if the total amount of interest had
been computed without giving effect to this Section 13.14. To the extent that
Chapter 303 of the Texas Finance Code is relevant for the purpose of determining
the Highest Lawful Rate, the Lender Parties elect to determine the applicable
rate ceiling under such Chapter by the indicated weekly rate ceiling from time
to time in effect.

         Section 13.15 Confidentiality; Section 20 Subsidiaries.

                  (a) In the event that the Borrower provides to the
Administrative Agent or the Lenders confidential information belonging to the
Borrower or any of its Affiliates, the Administrative Agent and the Lenders
shall thereafter maintain such information in confidence in accordance with the
standards of care and diligence that each utilizes in maintaining its own
confidential information. This obligation of confidence shall not apply to such
portions of the information which (i) are in the public domain, (ii) hereafter
become part of the public domain without the Administrative Agent or the Lenders
breaching their obligation of confidence to the Borrower, (iii) are previously
known by the Administrative Agent or the Lenders from some source other than the
Borrower and have been obtained by or available to the Administrative Agent or
the Lenders from a third party who owes no obligation of confidence to the
Borrower or any of its Affiliates with respect to such information or through
any other means other than through disclosure by the Borrower, (iv) are
hereafter developed by the Administrative Agent or the Lenders without using the
Borrower's or any of its Affiliates' information, (v) are hereafter obtained by
or available to the Administrative Agent or the Lenders from a third party who
owes no obligation of confidence to the Borrower or any of its Affiliates with
respect to such information or through any other means other than through
disclosure by the Borrower or any of its Affiliates, (vi) are disclosed with the
Borrower's consent, (vii) must be disclosed either pursuant to any Governmental
Requirement or to Persons regulating the activities of the Administrative Agent
or the Lenders, or (viii) as may be required by law or regulation or order of
any Governmental Authority in any judicial, arbitration or governmental
proceeding. Further, the Administrative Agent or a Lender may disclose any such
information to any other Lender, any independent petroleum engineers or
consultants, any independent certified public accountants, any legal counsel
employed by such Person in connection with this Agreement or any Security
Instrument, including without limitation, the enforcement or exercise of all
rights and remedies thereunder, or any assignee or participant (including
prospective assignees and participants) in the Loans; provided, however, that
the Administrative Agent or the Lenders shall receive a confidentiality
agreement for the benefit of the Borrower from the Person to whom such
information is disclosed such that said Person shall have the same obligation to
maintain the confidentiality of such information as is imposed upon the
Administrative Agent or the Lenders hereunder. Notwithstanding anything to the
contrary provided herein, this obligation of confidence shall cease three years
from the date the information was furnished, unless the Borrower requests in
writing at least 30 days prior to the expiration of such three year period, to
maintain the confidentiality of such information for an additional three year
period. The Borrower waives any and all other rights it may have to
confidentiality as against the Administrative Agent and the Lenders arising by
contract, agreement, statute or law except as expressly stated in this Section
13.15.

         Notwithstanding anything to the contrary, the Administrative Agent and
each Lender may disclose without limitation of any kind, any information with
respect to the "tax treatment" and "tax structure" (in each case, within the
meaning of Treasury Regulation Section 1.6011-4) of the transactions
contemplated hereby and all materials of any kind (including opinions or other
tax analyses) that are provided to the Administrative Agent or such Lender
relating to such tax treatment and tax structure; provided that with respect to
any document or similar item that in either case contains information concerning
the tax treatment or tax structure of the transaction as well as other
information, this sentence shall only apply to such portions of the document or



                                      -84-
<PAGE>

similar item that relate to the tax treatment or tax structure of the Revolving
Credit Loans, the Term A Loans, the Letters of Credit, the Direct Pay Letter of
Credit, and the transactions contemplated hereby.

                  (b) The Borrower acknowledges that from time to time financial
advisory, investment banking and other services may be offered or provided to
the Borrower, in connection with this Credit Agreement or otherwise, by a
Section 20 Subsidiary. The Borrower hereby authorizes (i) such Section 20
Subsidiary to share with the Administrative Agent and each Lender any
information delivered to such Section 20 Subsidiary by such Lender and (ii) the
Administrative Agent and each Lender to share with such Section 20 Subsidiary
any information delivered to the Administrative Agent or such Lender by the
Borrower pursuant to this Credit Agreement, or in connection with the decision
of such Lender to enter into this Credit 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 Credit Agreement. Such
authorization shall survive the payment and satisfaction in full of all of the
Obligations.

         Section 13.16 Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the Security
Instruments and agrees that it is charged with notice and knowledge of the terms
of this Agreement and the Security Instruments; that it has in fact read this
Agreement and is fully informed and has full notice and knowledge of the terms,
conditions and effects of this Agreement; that it has been represented by
independent legal counsel of its choice throughout the negotiations preceding
its execution of this Agreement and the Security Instruments; and has received
the advice of its attorney in entering into this Agreement and the Security
Instruments; and that it recognizes that certain of the terms of this Agreement
and the Security Instruments result in one party assuming the liability inherent
in some aspects of the transaction and relieving the other party of its
responsibility for such liability. Each party hereto agrees and covenants that
it will not contest the validity or enforceability of any exculpatory provision
of this Agreement and the Security Instruments on the basis that the party had
no notice or knowledge of such provision or that the provision is not
"conspicuous."

         Section 13.17 Arbitration.

                  (a) Arbitration. Upon the demand of any party, any Dispute
shall be resolved by binding arbitration in accordance with the terms of this
Agreement. A "Dispute" shall mean any action, dispute, claim or controversy of
any kind, whether in contract or tort, statutory or common law, legal or
equitable, now existing or hereafter arising under or in connection with, or in
any way pertaining to, this Agreement, or any past, present or future extensions
of credit and other activities, transactions or obligations of any kind related
directly or indirectly to this Agreement, including without limitation, any of
the foregoing arising in connection with the exercise of any self-help,
ancillary or other remedies pursuant to this Agreement. Any party may by summary
proceedings bring an action in court to compel arbitration of a Dispute. Any
party who fails or refuses to submit to arbitration following a lawful demand by
any other party shall bear all costs and expenses incurred by such other party
in compelling arbitration of any Dispute.

                  (b) Governing Rules. Arbitration proceedings shall be
administered by the American Arbitration Association ("AAA") or such other
administrator as the parties shall



                                      -85-
<PAGE>

mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All
Disputes submitted to arbitration shall be resolved in accordance with the
Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any
conflicting choice of law provision in this Agreement. The arbitration shall be
conducted at a location in Houston, Texas selected by the AAA or other
administrator. If there is any inconsistency between the terms hereof and any
such rules, the terms and procedures set forth herein shall control. All
statutes of limitation applicable to any Dispute shall apply to any arbitration
proceeding. All discovery activities shall be expressly limited to matters
directly relevant to the Dispute being arbitrated. Judgment upon any award
rendered in an arbitration may be entered in any court having jurisdiction;
provided however, that nothing contained herein shall be deemed to be a waiver
by any party that is a bank of the protections afforded to it under 12 U.S.C.
Section 91 or any similar applicable state law.

                  (c) No Waiver; Provisional Remedies, Self-Help and
Foreclosure. No provision hereof shall limit the right of any party to exercise
self-help remedies such as setoff, foreclosure against or sale of any real or
personal property collateral or security, or to obtain provisional or ancillary
remedies, including without limitation injunctive relief, sequestration,
attachment, garnishment or the appointment of a receiver, from a court of
competent jurisdiction before, after or during the pendency of any arbitration
or other proceeding. The exercise of any such remedy shall not waive the right
of any party to compel arbitration hereunder.

                  (d) Arbitrator Qualifications and Powers Awards. Arbitrators
must be active members of the State Bar of Texas with expertise in the
substantive laws applicable to the subject matter of the Dispute. Arbitrators
are empowered to resolve Disputes by summary rulings in response to motions
filed prior to the final arbitration hearing. Arbitrators (i) shall resolve all
Disputes in accordance with the substantive law of the state of Texas, (ii) may
grant any remedy or relief that a court of the state of Texas could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award recovery of all
costs and fees, to impose sanctions and to take such other actions as they deem
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure, the Texas Rules of Civil Procedure or other applicable law. Any
Dispute in which the amount in controversy is $5,000,000 or less shall be
decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees and expenses). By submission to a
single arbitrator, each party expressly waives any right or claim to recover
more than $5,000,000. Any Dispute in which the amount in controversy exceeds
$5,000,000 shall be decided by majority vote of a panel of three arbitrators;
provided however, that all three arbitrators must actively participate in all
hearings and deliberations.

                  (e) Judicial Review. Notwithstanding anything herein to the
contrary, in any arbitration in which the amount in controversy exceeds
$25,000,000, the arbitrators shall be required to make specific, written
findings of fact and conclusions of law. In such arbitrations (i) the
arbitrators shall not have the power to make any award which is not supported by
substantial evidence or which is based on legal error, (ii) an award shall not
be binding upon the parties unless the findings of fact are supported by
substantial evidence and the conclusions of law are not erroneous under the
substantive law of the state of Texas, and (iii) the parties shall have in
addition to the grounds referred to in the Federal Arbitration Act for vacating,
modifying or correcting an award the right to judicial review of (A) whether the
findings of fact rendered by the arbitrators are supported by substantial
evidence, and (B) whether the conclusions of law are



                                      -86-
<PAGE>

erroneous under the substantive law of the state of Texas. Judgment confirming
an award in such a proceeding may be entered only if a court determines the
award is supported by substantial evidence and not based on legal error under
the substantive law of the state of Texas.

                  (f) Miscellaneous. To the maximum extent practicable, the AAA,
the arbitrators and the parties shall take all action required to conclude any
arbitration proceedings within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulations, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provisions most
directly related to this Agreement or the subject matter of the Dispute shall
control. This arbitration provision shall survive termination, amendment or
expiration of this Agreement or any relationship between the parties.

         Section 13.18 USA Patriot Act Notice. Each Lender and the
Administrative Agent (for itself and not on behalf of any Lender) hereby
notifies the Borrower that pursuant to the requirements of the USA Patriot Act
(Title III of Pub. L. 107.56 (signed into law October 26, 2001)) (the "Act"), it
is required to obtain, verify and record information that identifies the
Borrower, which information includes the name and address of the Borrower and
other information that will allow such Lender or the Administrative Agent, as
applicable, to identify the Borrower in accordance with the Act.

         Section 13.19 Amendment and Restatement; Release. This Agreement amends
and restates in its entirety the Existing Credit Agreement. The execution of
this Agreement and the other Loan Documents executed in connection herewith does
not extinguish the indebtedness outstanding in connection with the Existing
Credit Agreement nor does it constitute a novation with respect to such
indebtedness. THE BORROWER REPRESENTS AND WARRANTS THAT AS OF THE DATE HEREOF
THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR COUNTERCLAIMS TO ITS OR
ANY OBLIGATED PARTIES' OBLIGATIONS UNDER THE EXISTING CREDIT AGREEMENT, THE
OTHER LOAN DOCUMENTS AND THE DOCUMENTATION RELATING TO THE DEPOSIT AND CASH
MANAGEMENT SERVICES. TO INDUCE THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND
THE LENDERS TO ENTER INTO THIS AGREEMENT, THE BORROWER AND, BY THE EXECUTION OF
THE LOAN DOCUMENTS TO WHICH IT IS A PARTY, EACH GUARANTOR WAIVES ANY AND ALL
CLAIMS, OFFSETS, DEFENSES OR COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING
PRIOR TO THE DATE HEREOF AND HEREBY RELEASES THE ADMINISTRATIVE AGENT, THE
LENDERS, THE ISSUING BANK AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS AND ATTORNEYS (COLLECTIVELY, THE "RELEASED PARTIES") FROM ANY AND ALL
OBLIGATIONS, INDEBTEDNESS, LIABILITY, CLAIMS, RIGHTS, CAUSES OF ACTION OR
DEMANDS WHATSOEVER, WHETHER KNOWN OR UNKNOWN, SUSPECTED OR UNSUSPECTED WHICH THE
BORROWER OR ANY GUARANTOR EVER HAD, NOW HAS, CLAIMS TO HAVE OR MAY HAVE AGAINST
ANY RELEASED PARTY ARISING PRIOR TO THE DATE HEREOF OR FROM OR IN CONNECTION
WITH THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR



                                      -87-

ANY DOCUMENTATION RELATING TO THE DEPOSIT AND CASH MANAGEMENT SERVICES OR THE
TRANSACTIONS CONTEMPLATED THEREBY.

                                  SCHEDULE 7.03

                                   LITIGATION

         There are no lawsuits pending against Borrower or, to the knowledge of
the Borrower, threatened against the Borrower, except for Nancy Ross, in her
capacity as the Trustee of the Trailmobile Trailer, LLC Liquidating Trust v. WCA
Waste Systems, Inc., Adv. No. 03A4552 in the U.S. Bankruptcy Court for the
Northern District of Illinois, Eastern Division; the Borrower is improperly
named in this suit, which is a preference claim against Waste Corporation of
Arkansas, Inc. This case is not covered by insurance; however, Borrower has no
reason to believe that the potential liability, if any, resulting from this case
would constitute a Material Adverse Effect with respect to the Borrower or Waste
Corporation of Arkansas, Inc.

         There are no lawsuits pending or threatened against any Subsidiary that
the Borrower believes will have a Material Adverse Effect on either the Borrower
or any Subsidiary, based upon the posture of such lawsuits at this time.

         The Borrower does not believe that any of the following items are
material, either individually or in the aggregate, and does not believe that an
adverse determination of any of the following, either individually or in the
aggregate, would result in a Material Adverse Effect, based upon the current
posture of such litigation. However, for purposes of disclosure, the Borrower
identifies the following:

       1.     Certain Subsidiaries have the following lawsuits pending that, to
              Borrower's knowledge and reasonable belief, are covered by the
              insurance described in Schedule 7.19 (the "Insurance"): Waste
              Corporation of Arkansas, Inc. is a named defendant in Essex
              Insurance Co. v. Waste Corporation of Arkansas, Inc., Case No. CV
              2004-46(L) in the Circuit Court of Craighead County, Arkansas,
              Civil Division, Western District and Cledia Graves, Sr., et al. v.
              Waste Corporation of Arkansas, Inc., Case No. CIV 2002-420 in the
              Circuit Court of Phillips County, Arkansas, Civil Division (the
              "Arkansas Cases"); Waste Corporation of Missouri, Inc. and Charles
              Dodd are named defendants in Robert Campbell, et al. v. Waste
              Corporation of Missouri, Inc., et al., Case No. CVCV8-03-446-CC in
              the Circuit Court of Texas County, Missouri and Edward L. Booth v.
              Waste Corporation of Missouri, Inc., Case No. CV103-429CC in the
              Circuit Court of Camden County, Missouri (the "Missouri Cases");
              WCA of Alabama, LLC is a named defendant in Fines Recycling, Inc.
              v. Waste Corporation of America, Inc., et al., Case No. CV
              2002-286 in the Circuit Court of Talladega Country, Alabama (the
              "Alabama Case"). In addition to the Arkansas Cases, the Missouri
              Cases, and the Alabama Case, there are claims in Missouri, Texas
              and Arkansas for damages which have been asserted but not in the
              context of litigation.

              The Borrower has no reason at this time to believe that all of the
              above-referenced matters will not be covered by its general
              liability, automobile liability, and/or excess liability insurance
              policies, subject to standard deductibles.



<PAGE>



       2.     Waste Corporation of Arkansas, Inc. is a named defendant in
              Official Committee of Unsecured Creditors, on behalf of the
              estates of Tandycrafts, Inc., TAC Holdings, Inc. and Tandyarts,
              Inc. v. Waste Corporation of Arkansas, Inc., Adv. No. 03-53327 in
              the U.S. Bankruptcy Court for the District of Delaware. This case
              is not covered by Insurance; however, Borrower has no reason to
              believe that the potential liability, if any, resulting from this
              case would constitute a Material Adverse Effect with respect to
              either the Borrower or Waste Corporation of Arkansas, Inc.

       3.     In addition, Waste Corporation of America, LLC and certain other
              subsidiaries have been named as defendants in various lawsuits
              that have been tendered to, and are being defended by, the
              carriers of the Insurance, and Borrower has no reason to believe
              that such litigation will not be covered by such insurance subject
              to standard deductible. These suits do not involve the Borrower or
              any Subsidiary; however, these suits arose prior to the 2004
              Reorganization. At this time Borrower has no reason to believe
              that any such proceedings against Waste Corporation of America,
              LLC or any such subsidiary are reasonably expected to result,
              individually or in the aggregate, if adversely determined to such
              parties, in a Material Adverse Effect.

       4.     Finally, Waste Corporation of America, LLC and certain other
              subsidiaries are engaged in various legal proceedings other than
              state or federal court litigation which have arisen but have not
              been fully adjudicated. These suits do not involve the Borrower or
              any Subsidiary; however, these suits arose prior to the 2004
              Reorganization. At this time Borrower has no reason to believe
              that any such proceedings against Waste Corporation of America,
              LLC or any such subsidiary are reasonably expected to result,
              individually or in the aggregate, if adversely determined to such
              parties, in a Material Adverse Effect.

                              ENVIRONMENTAL MATTERS

         Following is a list of all material operating permits for the landfills
and transfer stations operated by the Borrower's operating subsidiaries (the
"Operating Permits"). In addition to the Operating Permits, the operating
subsidiaries have numerous other permits, licenses, consents and approvals for
the operation of the businesses of such operating subsidiaries, including NPDES
permits, air permits, local business licenses, and transport permits. In
addition, many of the permits, licenses, consents and approvals expire over
time, and application for renewal must occur. Neither Borrower nor any
subsidiary lacks any permit, license, consent or approval wherein such failure
to obtain or maintain such permit, license, consent or approval would have a
Material Adverse Effect on the business of the Borrower or any such subsidiary.

                               MATERIAL AGREEMENTS

1.       Waste Corporation of Missouri, Inc. ("WCM") contracts with two
         companies for operating and hauling waste from certain WCM transfer
         stations, to WCM landfills. These contracts are for a term of five
         years. These contracts have been previously provided to the
         Administrative Agent.

2.       Waste Corporation of Missouri, Inc. ("WCM") contracts with the Phelps
         County Landfill Board for the operation of the Phelps County transfer
         station. This contract is for a term of five years. These contracts
         have been previously provided to the Administrative Agent.

3.       Waste Corporation of Arkansas, Inc. ("WCA") contracts with a company
         for hauling waste from the Searcy transfer station to the Rolling
         Meadows Landfill. This contract is for a term of one year. These
         contracts have been previously provided to the Administrative Agent.

4.       Waste Corporation of Arkansas, Inc. ("WCA") contracts with the City of
         Searcy for the operation of the Searcy transfer station. This contract
         is for a term of fifteen years (with early termination provisions).
         These contracts have been previously provided to the Administrative
         Agent.

5.       The Borrower, through the Subsidiaries, engage in significant
         contractual relations with customers which utilize assets of the
         Subsidiaries (e.g., trucks, containers, and landfills), which assets
         were acquired by the Subsidiaries with the proceeds of Debt. While
         these contracts may be broadly categorized as "relating to any Debt"
         (because the assets utilized to service these contracts were acquired
         with the proceeds of Debt), the Borrower is not listing any such
         customer contracts.

6.       Many customer contracts require surety bonds to be in place to assure
         performance under the contract. Material surety bonds are set forth on
         page 3 of this Schedule 7.21.

7.       Page 2 of this Schedule 7.21 is a Summary of the long-term debt of the
         Borrower and the subsidiaries incurred in connection with (a) the
         purchase of specific pieces of equipment, and (b) notes payable
         incurred in connection with the payment of insurance premiums. This
         summary excludes all Obligations.

8.       Schedule 1.2 lists all obligations in respect of Letters of Credit.
