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. In the event the
Borrower terminates or reduces the Aggregate Revolving Credit Commitments
pursuant to this Section 2.03(b), any such termination or reduction shall be
applied first to Wells Fargo's Revolving Credit Commitment until Wells Fargo's
Revolving Credit Commitment is $50,000,000 ("Desired WFB Commitment Level"), and
then, the remainder, if any, shall be applied to the Commitment of each Lender
(including Wells Fargo), pro rata according to the amounts of its respective
Commitment.

          (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, (ii) the
Borrower has terminated or reduced the Aggregate Revolving Credit Commitments
pursuant to Section 2.03(b) such that Wells Fargo's Revolving Credit Commitment
equals the Desired WFB Commitment Level, and (iii) the Borrower has not
otherwise terminated or reduced in part any

                                      -27-
<PAGE>
unused portion of the Aggregate Revolving Credit Commitments at any time
pursuant to Section 2.03, the Borrower may by notice to the Administrative
Agent, request a one-time increase in the amount of the Aggregate Revolving
Credit Commitments within the 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 Forty Million Dollars ($40,000,000); (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

                                      -28-
<PAGE>
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 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).

                                      -29-
<PAGE>
          (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 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>

The commitment fee percentage shall be established as of each Determination Date
beginning with the fiscal quarter ending December 31, 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 December 31, 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 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

                                      -31-
<PAGE>
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 2.10(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

                                      -32-
<PAGE>
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 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

                                      -33-
<PAGE>
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 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

                                      -34-
<PAGE>
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.

          (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.

                       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 January 1, 2005, 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(b).

          (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) (subject to the
last sentence

                                      -37-
<PAGE>
thereof) shall be applied to the 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).

          (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

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.

                                      -48-
<PAGE>
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,

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

                                      -49-
<PAGE>
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 September 30, 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 September 30, 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 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

                                      -50-
<PAGE>
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 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.

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

                                      -51-
<PAGE>
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.

          (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

                                      -52-
<PAGE>
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

in all material respects in the same manner as its business has been conducted
prior to the Closing Date.

          (d) All of the assets and Properties of the Borrower and its
Subsidiaries which are material to the operation of its business are in good
working condition, ordinary wear and tear excepted, and are maintained in

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
is reasonably likely to have (so far as the Borrower can now foresee) a Material
Adverse Effect and which has not been set forth in this Agreement or the other
documents, certificates and statements furnished to the Administrative Agent by
or on behalf of the Borrower or any Subsidiary prior to, or on, the Closing Date
in connection with the transactions contemplated hereby.

     Section 7.12 Investment Company Act. Neither the Borrower nor any

as amended.

any Subsidiary is a "holding company," or a "subsidiary company" of a "holding
company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," or a

                                      -53-
<PAGE>
"public utility" within the meaning of the Public Utility Holding Company Act of
1935, as amended.

Borrower has no Subsidiaries.

     Section 7.15 Location of Business and Offices. The Borrower's principal

     Section 7.16 Defaults. Neither the Borrower nor any Subsidiary is in
default nor has any event or circumstance occurred which, but for the expiration
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
Borrower or any Subsidiary is a party or by which the Borrower or any Subsidiary
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
expected to have a Material Adverse Effect), to the best knowledge of the
Borrower, after due inquiry:

          (a) Neither any Property of the Borrower or any Subsidiary nor the
operations conducted thereon violate any order or requirement of any court or
Governmental Authority or any Environmental Laws;

          (b) Without limitation of clause (a) above, no Property of the
Borrower or any Subsidiary nor the operations currently conducted thereon or, to
the best knowledge of the Borrower, by any prior owner or operator of such
Property or operation, are in violation of or subject to any existing, pending
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 of any
and all Property of the 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 or filed, or to the extent not
obtained or filed, will be obtained or filed in the ordinary course of business,
and the Borrower and each Subsidiary are in compliance with the terms and
conditions of all such notices, permits, licenses and similar authorizations;

          (d) All hazardous substances, solid waste, and oil and gas exploration

accordance with Environmental Laws and so as not to pose an imminent and
substantial endangerment to public health or welfare or the environment, and, to
the best knowledge of the Borrower, all such transport carriers and

                                      -54-
<PAGE>
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;

          (g) Neither the Borrower nor any Subsidiary has any known contingent
liability in connection with any release or threatened release of any oil,
hazardous substance or solid waste into the environment; and

          (h) (i) no portion of the real Property of the Borrower or any
Subsidiary has been used for the handling, processing, storage or disposal of
hazardous substances; and no underground tank or other underground storage
receptacle for hazardous substances is located on such Properties; (ii) in the
course of any activities conducted by the Borrower, or operators of such real
Property, no hazardous substances have been generated or are being used on such
Properties; (iii) there have been no unpermitted releases or threatened releases
of hazardous substances on, upon, into or from the real Property of the Borrower
or any Subsidiary; (iv) to the best of the Borrower's knowledge, there have been
no releases on, upon, from or into any real property in the vicinity of such
real Property, which, through soil or groundwater contamination, may have come
to be located on such Properties; and (v) in addition, when required under
applicable Environmental Laws, any hazardous substances that have been generated
on 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

                                      -55-
<PAGE>
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 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

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

and governmental charges or levies imposed on it or on its income or profits or

being contested in good faith and by proper proceedings and against which
adequate reserves are being maintained; upon reasonable notice and under
conditions that do not unreasonably interfere with the Borrower's or any
Subsidiaries' business, permit representatives of the Administrative Agent or
any Lender, during normal business hours, to examine, copy and make extracts
from its books and records, to inspect its Properties, and to discuss its
business and affairs with its officers, all to the extent reasonably requested

financial statements required by Section 8.01(a) to be delivered for each year,

sufficient number of copies for each Lender of certificate of insurance coverage
from the insurer in form and substance satisfactory to the Administrative Agent

otherwise permitted under this Agreement, are in the ordinary course of its
business and are upon fair and reasonable terms no less favorable to it than it
would obtain in a comparable arm's length transaction with a Person not an
Affiliate; provided, however, that the Borrower and its Subsidiaries may provide
general and administrative services to its Affiliates and to Waste Corporation
and any of its Subsidiaries, with or without reimbursement or compensation, all
pursuant to service agreements in form and substance reasonably satisfactory to

                            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

     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

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.

               (ii) to indemnify the Administrative Agent and each Lender and

Parties") from, hold each of them harmless against and promptly upon demand pay
or reimburse each of them for, the Indemnity Matters which may be incurred by or
asserted against or involve any of them (whether or not any of them is

related to (i) any actual or proposed use by the Borrower or Waste Corporation
Texas of the proceeds of any of the Loans, the Direct Pay Letter of Credit or
Letters of Credit, (ii) the execution, delivery and performance of the Loan

Matters arising by reason of the ordinary negligence of any Indemnified Party,
but excluding all Indemnity Matters arising solely by reason of claims between
the Lenders or any Lender and the Administrative Agent or a Lender's
shareholders against the Administrative Agent or Lender or by reason of the
gross negligence or willful misconduct on the part of any Indemnified Party; and

               (iii) to indemnify and hold harmless from time to time the
Indemnified Parties from and against any and all losses, claims, cost recovery
actions, administrative orders or proceedings, damages and liabilities to which
any such Person may become subject (i) under any Environmental Law applicable to
the Borrower or any Subsidiary or any of their Properties,

                                      -77-
<PAGE>

health or safety condition in connection with the Loan Documents; provided,
however, no indemnity or hold harmless protection shall be afforded under this
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

shall bear its own cost of defense unless there is a conflict between the
Borrower and such Indemnified Party.

          (d) Except as expressly provided in the proviso to clause (iii) of
Section 13.03(a) above, the foregoing indemnities shall extend to the
Indemnified Parties notwithstanding the sole or concurrent negligence of every
kind or character whatsoever, whether active or passive, whether an affirmative
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
shall only extend to the portion of the claim that is deemed to have occurred by
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 survive
any termination of this Agreement and the payment of the Notes and shall
continue thereafter in full force and effect.

          (f) The Borrower shall pay any amounts due under this Section 13.03
within 30 days of the receipt by the Borrower of notice of the amount due.

     Section 13.04 Amendments, Etc. Any provision of this Agreement or any
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; (ii) no amendment,
modification or waiver which increases the Revolving Credit 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

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

                                      -79-
<PAGE>
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 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.

                                      -80-
<PAGE>
          (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 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

     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.

<PAGE>
PARTIES RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF. THE LOAN DOCUMENTS

     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 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

                                      -82-
<PAGE>
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 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

                                      -83-
<PAGE>
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 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.

                                      -84-
<PAGE>
          (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 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

                                      -85-
<PAGE>
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 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.

                                      -86-
<PAGE>
          (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 ANY DOCUMENTATION RELATING TO THE DEPOSIT
AND CASH MANAGEMENT SERVICES OR THE TRANSACTIONS CONTEMPLATED THEREBY.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (this "Agreement"), dated as of March 22,
2005, is entered into between WCA Management Company, L.P. (the "Company"), WCA
Waste Corporation (the "Guarantor") and Tom J. Fatjo, Jr. (the "Executive"), and
is effective as of January 1, 2005 (the "Effective Date").

                                    RECITALS

         A. The Company has previously determined that it is in the best
interest of the Company and its equity holders to retain the Executive and to
induce the continued employment of the Executive for the long term benefit of
the Company.

         B. The Company desires to continue the employment of the Executive on
the terms set forth below to provide services to the Company and its affiliates,
and the Executive is willing to continue such employment and to continue to
provide such services on the terms set forth in this Agreement.

         C. The Guarantor has determined that it is in the best interests of the
Guarantor to facilitate such retention and continued employment of the Executive
by the Company by guaranteeing the Company's obligations under this Agreement.

         D. In consideration of the foregoing and the mutual terms, conditions,
and covenants set forth herein, and for other good and valuable consideration,
the parties hereto do hereby agree as set forth herein.

         1. Term of Employment. The Company hereby agrees to employ the
Executive, and the Executive hereby agrees to remain in the employ of the
Company, for a three-year period commencing on the Effective Date of this
Agreement and continuing until the day before the third anniversary of the
Effective Date, plus any extensions made in accordance with the provisions of
this Section 1 (the "Term"). On the first day of each month occurring after the
Effective Date, the initial Term (and any extended Term) shall automatically be
extended for an additional calendar month unless prior to any such first day of
the affected calendar month, the Company or Executive shall have given notice
not to extend the Term. The Company and Executive agree that any such notice by
the Company shall constitute "Good Reason" as defined in Section 2(d) for
Executive to terminate Executive's employment. This Agreement shall terminate on
the earlier of (a) the last day of the Term or (b) such earlier date as this
Agreement is terminated pursuant to Section 2. Nothing in this Section 1 shall
limit the right of the Company or Executive to terminate Executive's employment
hereunder subject to the terms and conditions of Sections 7, 10 and 11 and other
applicable provisions of this Agreement.

<PAGE>

         2. Termination of Employment. Executive's employment with the Company
shall terminate upon the earliest of:

         (a) the death of the Executive;

         (b) at any time after Executive has been receiving full or partial
salary payments under the Company's disability plans for a period of 18
consecutive months by reason of any medically determinable physical or mental
impairment which can be expected to result in death or can be expected to last
for a continuous period of not less than 12 consecutive months, either the
Company or Executive sending the other party written notice that Executive is
"permanently disabled" as defined above in this Section 2(b); provided, however,
that during any period prior to such termination of this Agreement in which
Executive is receiving full or partial salary payments under the Company's
disability insurance policies, the obligation of the Company to pay Executive
salary pursuant to Section 4 shall cease;

         (c) the Company's sending Executive written notice that Executive's
employment is terminated for "cause" which term shall mean (i) the willful
material breach by Executive of this Agreement, (other than any breach resulting
from Executive's incapacity due to physical or mental illness), which breach
continues for thirty (30) days after actual receipt of written notice from the
Company and which results in, or is reasonably likely to result in, demonstrable
material damage to the Company, (ii) Executive's conviction of or plea of guilty
to a felony or Executive's conviction of a crime involving moral turpitude,
(iii) Executive's engagement in the fraud of the Company or the misappropriation
or embezzlement of funds from the Company, (iv) or Executive's reckless
disregard or willful misconduct which misconduct, if ongoing, (as distinguished
from an isolated incident), continues for thirty (30) days after actual receipt
of written notice from the Company and which results in, or is reasonably likely
to result in, demonstrable and material damage to the Company;

         (d) the Executive's sending the Company written notice that Executive's
employment is terminated for "Good Reason" which term shall mean the occurrence
(without the Executive's express written consent) of any one of the following
acts by the Company, or failures by the Company to act, unless, in the case of
any act or failure to act described below, such act or failure to act is
corrected within thirty (30) days after actual receipt of written notice from
Executive: (i) the Company's breach of a material term or condition of the
Agreement; (ii) except for any changes required by applicable law, the failure
by the Company to continue in effect any compensation plan in which the
Executive participates immediately prior to the date hereof which is material to
the Executive's total compensation, including but not limited to the Company's
annual incentive plan, long-term incentive plan, supplemental executive
retirement plan and equity incentive plan, as applicable, unless an equitable
arrangement (embodied in an ongoing substitute or alternative plan) has been
made with respect to such plan; (iii) the Company's asking or requiring the
Executive to take (or not to take) any action which the Executive in good faith
reasonably believes could be materially misleading to the Company's employees,
investors, accountants or attorneys and/or any regulatory authority; or (iv)
notice by the Company to the Executive under Section 1 that the Term will not be
extended; provided, however, that the Executive's right to terminate the
Executive's employment for Good Reason shall not be affected by the Executive's
incapacity due to physical or mental illness.

                                       2

Notwithstanding any other provision of this Section 2(d) to the contrary, within
ninety (90) days (or such other period as the parties may agree to in writing)
following any date on which an act by the Company or failure to act by the
Company gives rise to the right of Executive to terminate employment by the
Company for Good Reason, Executive shall provide the Company written notice that
Executive's employment is terminated, and any failure to comply with the
requirements of this sentence shall be conclusively deemed to be a waiver by
Executive of the right to terminate his employment hereunder for Good Reason
that is based on that act or failure to act by the Company.

         3. Position and Duties.

         (a) The Executive's positions shall be those of Chairman and Chief
Executive Officer, and in such capacity Executive shall perform the customary
duties and responsibilities of the positions. Subject to the Company's actual
receipt of prior written consent of Executive, these positions, duties, and
responsibilities can be modified as required to suit the specific requirements
and needs of the Company, provided that any such modification shall result in
substantially similar, comparable or higher positions, duties and
responsibilities. Similarly, subject to the Company's actual receipt of prior
written consent of Executive, the Company may assign Executive part time or full
time to a subsidiary in which case the subsidiary shall be jointly and severally
responsible as, and shall be treated as, the Company under this Agreement for
the period of time the Executive performs services for the subsidiary.
Executive's place of employment will be located within the greater Houston,
Texas metropolitan area, but Executive will undertake appropriate business
travel as required by the Company.

         (b) Executive agrees to conduct all business in accordance with the
Company's general policies/directives as they may exist at any given time.
Executive shall comply materially with all applicable laws and regulations of
the countries in which the Company and its affiliates operate.

         (c) Executive agrees to devote his full time, attention, and efforts
during regular business hours, and at all such other times as may be requested
by the Company, consistent with industry practices, to the business affairs of
the Company during the Term of this Agreement and to perform his duties
faithfully and diligently to discharge the responsibilities assigned to the
Executive hereunder. The foregoing notwithstanding, the parties recognize and
agree that Executive may engage in passive personal investments and other
business, civic or charitable activities that do not conflict with the business
and affairs of the Company or interfere with Executive's performance of his
duties hereunder.

         4. Salary. Except if Executive's employment is terminated pursuant to
Section 2(a), (b), (c) or (d) (in which case Section 7(a) applies) and except as
otherwise provided in Section 2(b), during the Term, the Company shall pay
Executive a base salary of $357,719 per year, payable bi-monthly ("Base
Salary"). The Base Salary will be increased each year on the anniversary
(beginning January 1, 2006) of the Employment Agreement by not less than the
increase during the immediately preceding year in the Consumer Price Index for
the Houston Standard Metropolitan Statistical Area.

                                       3
<PAGE>

         5. Annual/Long-Term Incentives. During the Term, Executive shall
participate in the Guarantor's annual incentive plan (i.e., the Management
Incentive Plan or any successor thereto) and shall have the opportunity to earn
an annual bonus for the applicable measurement period of up to one hundred
percent (100%) of Executive's Base Salary based on performance measures and
annual incentive plan goals as shall be established by the Compensation
Committee pursuant to the terms of such plan. In addition, during the Term,
Executive shall participate, on comparable terms, in the Guarantor's long term
incentive plan (i.e., the Performance Unit Plan or any successor thereto) in
which similarly situated executives of the Company participate. Also, during the
Term, as soon as practicable following the Effective Date and the first day of
each of 2006 and 2007, Executive shall receive grants of restricted stock under
the 2004 WCA Waste Corporation Incentive Plan (or any successor thereto) in an
amount equal to the result obtained by dividing one hundred percent (100%) of
Executive's Base Salary for the relevant year by the fair market value of one
share of common stock of the Guarantor on the date of grant of the restricted
stock; provided, however, the parties expressly agree that for this purpose, the
fair market value of such share shall never be less than nine dollars and fifty
cents ($9.50) a share.

         6. Benefits. Except if Executive's employment is terminated pursuant to
Section 2(a), (b), (c) or (d) (in which case Section 7(a) applies), during the
Term, Executive and, to the extent applicable, Executive's family, dependents
and beneficiaries may participate in the benefit or similar plans, policies or
programs (including, without limitation, the Company's business and
entertainment expense reimbursement policies, car allowance policies, 401(k)
plans, disability plans, pension plans, health insurance plans and director and
officer liability insurance policies) provided to similarly-situated Executives
under the Company's standard employment practices as in effect from time to
time. Nothing herein shall be construed to require the Company to continue or
put into effect any plan, practice, policy, or program or any element thereof.
In addition, during the Term, Executive shall be entitled to three (3) weeks of
paid vacation days annually pursuant to applicable policies and procedures of
the Company as in effect from time to time.

         7.       Effects of Termination of Employment.

         (a) Subject to the provisions of this Section 7, upon termination of
Executive's employment with the Company for any reason whatsoever, the Company
shall pay to Executive (or in case of Executive's death, to his estate), within
thirty (30) days of the effective date of such termination, all salary and
expense reimbursements due to Executive through the date of such termination,
and Executive shall be entitled to such benefits as are available pursuant to
the terms of any benefit or similar plans, policies or programs in which
Executive was participating at the time of such termination pursuant to Section
6 of this Agreement. In addition, upon termination of Executive's employment
with the Company for death or permanent disability, in lieu of any further
salary or bonus payments as severance to Executive for periods subsequent to
such termination and in lieu of any other severance otherwise payable to
Executive, the Company will pay to Executive (or to his estate, as applicable),
within thirty (30) days of such termination, a lump sum severance payment, in
cash equal to the Executive's Base Salary for the Remaining Term of the
Agreement as in effect immediately prior to such termination of Executive's
employment. Also, if the Company terminates the Executive's employment for any
reason other than those set forth in Sections 2(a), (b) or (c), or if Executive
terminates

                                       4
<PAGE>

Executive's Employment under Section 2(d), the Company shall continue throughout
the full Term of this Agreement to pay Executive's salary pursuant to Section 4,
to continue coverage in any annual and long-term incentive plans pursuant to
Section 5 and to provide Executive's benefits pursuant to Section 6 (and, if the
Company pays Executive's salary and provides Executive's benefits for the full
Term of this Agreement, Executive shall be subject to the covenants contained in
Section 9 through the full term of this Agreement).

         (b) Notwithstanding any termination of this Agreement or Executive's
employment hereunder, this Section 7 and Sections 10 and 11 of this Agreement,
and the rights and obligations created therein, shall survive without
limitation.

         (c) Notwithstanding any provision of this Agreement, it is the
intention of the parties hereto that there shall be no duplication of benefits
if the circumstances of Executive's termination of employment would otherwise
entitle Executive to payments and benefits under this Section 7 and under
Section 10. Accordingly, in the event of such a termination, if a particular
type of benefit is payable under both Section 7 and Section 10, the Company
shall in good faith compare the two benefits and Executive shall be paid the
greater of the two benefits. Such payment shall be accepted by Executive in lieu
of the lesser benefit otherwise provided under this Agreement.

         8. Tax Withholding. All payments to Executive under this Agreement
shall be subject to withholding or deduction of such amounts as may be required
by law.

         9. Noncompetition and Confidentiality.

         (a) The parties recognize that the employment of Executive with the
Company has been and will continue to be special, unique and of an extraordinary
character, and in connection with such employment Executive has and will
continue to acquire special skill and training. The parties also recognize that
the covenants of Executive contained in this Section 9 are an essential part of
Executive's engagement by the Company and that, but for the agreement of the
Executive to comply with such covenants, the Company would not have entered into
this Agreement. Executive accordingly agrees that, during the Term, (i)
Executive shall not act or serve, directly or indirectly, as a principal, agent,
independent contractor, consultant, director, officer, executive, employee or
advisor or in any other position or capacity with or for, or acquire a direct or
indirect ownership interest in or otherwise conduct (whether as stockholder,
partner, investor, joint venturer, or as owner of any other type of interest),
any Competing Business (defined below); provided, however, that this clause
shall not prohibit the Executive from being the owner of (A) up to 5% of any
class of outstanding securities of any entity if such class of securities is
publicly traded or (B) any other securities owned by Executive on the date of
this Agreement, and (ii) Executive shall not, in connection with or for the
benefit of any person or entity engaged in the non-hazardous solid waste
business, solicit, induce, divert or take away, any officer, employee or
consultant of the Company.

         (b) From the date hereof, Executive shall hold in secrecy for the
Company all trade secrets and other confidential information relating to the
business and affairs of the Company that have come or may have come to his
attention during his employment with the Company,

                                       5
<PAGE>

including information concerning costs, profits, markets, sales, business
development plans, lists of clients or customers, lists of acquisition targets
and other information about such acquisition targets and other information of a
similar nature (such categories of information being referred to herein as
"Confidential Information"). Executive shall not use for his own benefit or
disclose to any person any Confidential Information other than in the ordinary
course of the Company's business or in response to a court order, unless such
use or disclosure has the prior written authorization of the Company. Executive
shall deliver to the Company, upon request, all correspondence, memoranda,
notes, records, plans, customer lists, product compositions and other documents
and all copies thereof, whether in hard copy form or electronically or
magnetically stored, made, composed, or received by the Executive, solely or
jointly with others, that are in the Executive's possession, custody or control
and that are related in any manner to the past, present or anticipated business
of the Company.

         (c) For the purposes of this Section 9, "Competing Business" shall mean
an individual, business, corporation, association, firm, undertaking,
partnership, joint venture, organization or other entity that operates
non-hazardous solid waste landfills, non-hazardous solid waste collection
businesses or similar facilities or businesses within a 50-mile radius of any of
the landfills or similar facilities of the Company, Guarantor or any affiliate
thereof.

         (d) Should any portion of this Section 9 be deemed unenforceable
because of the scope, duration or territory encompassed by the undertakings of
the Executive hereunder, and only in such event, then the Executive and the
Company consent and agree to such limitation on scope, duration or territory as
may be finally adjudicated as enforceable by a court of competent jurisdiction
after the exhaustion of all appeals.

         (e) The covenants in this Section 9 shall be construed as an agreement
ancillary to the other provisions of this Agreement, and the existence of any
claim or cause of action of the Executive against the Company, whether
predicated on this Agreement or otherwise, other than a claim or cause of action
based on the Company's failure to pay Executive amounts payable to Executive
hereunder, shall not constitute a defense to the enforcement by the Company of
this covenant.

         (f) It is expressly recognized and agreed that the covenants set forth
in this Section 9 are for the purpose of restricting the activities of the
Executive only to the extent necessary for the protection of the legitimate
business interests of the Company, and the Company and the Executive agree that
said covenants are reasonable for that purpose and that such covenants do not
and will not preclude Executive from engaging in activities sufficient for the
purpose of earning a living.

         10. Additional Consideration.

         (a) Change in Control. In the event of the occurrence of a "Change in
Control" (defined below), and, within twenty-four (24) months following such
Change in Control, Executive's employment shall be involuntarily terminated for
any reason other than for cause or Executive shall (i) suffer a significant
reduction in reporting level (as determined by Executive in good faith), (ii)
suffer a reduction in Base Salary and annual incentive compensation at target by
ten percent (10%) or more or (iii) be required to relocate from the regular
assigned work place by

                                       6
<PAGE>

more than fifty (50) miles from Executive's regular assigned work place, the
Company shall pay to Executive, within thirty (30) days after the event
following such Change in Control that gives rise to the payment due hereunder, a
lump sum payment, in cash, equal to three (3) times the sum of (i) Executive's
annual Base Salary as in effect immediately prior to the Change in Control and
(ii) Executive's Average Annual Bonus (defined below). "Change in Control" shall
mean the occurrence during the Term of this Agreement, of an one of the
following events:

                  (i) An acquisition of any common stock ("Common Stock"), par
         value $.01 per share, of the Guarantor or other securities entitled to
         vote, or convertible into or exercisable for securities entitled to
         vote, in the election of directors (such Common Stock and other
         securities hereinafter being referred to as the "Voting Securities") of
         the Guarantor by any Person (as specified in Section 3(a)(9) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
         used in Sections 13(d) and 14(d) thereof), including for purposes of
         this Section the Guarantor or its Affiliates, immediately after which
         such Person has Beneficial Ownership (as defined below) of fifty
         percent (50%) or more of the combined voting power of the Guarantor's
         then outstanding Voting Securities; provided, however, a Change in
         Control shall not be deemed to have occurred by reason of an
         acquisition of fifty percent (50%) or more of the Guarantor's Voting
         Securities by an employee benefit plan maintained by the Guarantor or
         any of its Affiliates or by a Person in a Non-Control Transaction (as
         defined below); or

                  (ii) The individuals who, as of the date of this Agreement are
         members of the Board of Directors of the Guarantor (the "Incumbent
         Board"), cease for any reason to constitute at least two/thirds (2/3)
         of the members of the Board of Directors of the Guarantor; provided,
         however, that an individual will be treated as a member of the
         Incumbent Board if the members of the Board of Directors of the
         Guarantor prior to such individual's nomination unanimously approve
         such individual's nomination and election to the Board of Directors of
         the Guarantor and provided further that no individual shall be
         considered a member of the Incumbent Board if such individual initially
         assumed office as a result of either an actual or threatened proxy
         contest or other actual or threatened solicitation of proxies or
         consents by or on behalf of a Person other than the Board of Directors
         of the Guarantor (a "Proxy Contest"), including by reason of any
         agreement intended to avoid or settle any Proxy Contest; or

                  (iii)    The consummation of:

                           (A)      A merger, consolidation or reorganization
                                    with or into the Guarantor or in which
                                    securities of the Guarantor are issued (a
                                    "Merger"), unless such Merger, consolidation
                                    or reorganization occurs in connection with
                                    a Non-Control Transaction;

                           (B)      A complete liquidation or dissolution of the
                                    Guarantor; or

                           (C)      The sale or other disposition of all or
                                    substantially all of the assets of the
                                    Guarantor to any Person (other than a
                                    transfer to an employee benefit plan or
                                    Affiliate of the Guarantor or under
                                    conditions that would constitute a
                                    Non-Control Transaction with

                                       7
<PAGE>

                                    the disposition of assets being regarded as
                                    a Merger for this purpose).

         As used in the above definition of Change in Control, the following
terms have the following meanings:

                  (i) "Affiliate" shall have the meaning set forth in Rule 12b-2
         promulgated under Section 12 of the Exchange Act.

                  (ii) "Beneficial Ownership," "Beneficially Owned" and the like
         means having, with respect to a security or group of securities, the
         power to control or direct the voting or disposition of Voting
         Securities, as determined by Rule 13d-3 under the Exchange Act.

                  (iii) "Non-Control Transaction" means a Merger whereby (A) the
         individuals who were the president, chief executive officer and the
         chief financial officer of the Guarantor hold such respective positions
         with, and individuals who were members of the Incumbent Board
         immediately prior to the execution of the agreement providing for the
         Merger, constitute at least a majority of the members of the board of
         directors of, the surviving corporation and (B) either (1) fifty
         percent (50%) or more of the combined voting power of the then
         outstanding voting securities of the surviving corporation is
         Beneficially Owned directly by the Beneficial Owners of the Guarantor's
         Voting Securities prior to the Merger or (2) the president, chief
         executive officer and/or chief financial officer of the Company, as a
         result of such Merger, acquire (or their Affiliates acquire) fifty
         percent (50%) or more of the combined voting power of the then
         outstanding voting securities of the surviving corporation.

                  This definition of Change in Control is intended to comply
         with the definition of change in control under Section 409A of the
         Internal Revenue Code of 1986, as amended (the "Code"), as in effect
         from time to time and, to the extent that the above definition does not
         so comply, such definition shall be void and of no effect and, to the
         extent required to ensure that this definition complies with the
         requirements of Section 409A of the Code, the definition of such term
         set forth in regulations or other regulatory guidance issued under
         Section 409A of the Code by the appropriate governmental authority is
         hereby incorporated by reference into and shall form part of this
         Agreement as fully as if set forth herein verbatim and the Agreement
         shall be operated in accordance with the definition prescribed in such
         regulations or other regulatory guidance.

                  "Average Annual Bonus" shall mean the average annual bonus
         earned by the Executive pursuant to any annual bonus plan maintained by
         the Company in which the Executive participated in respect of any of
         the three (3) consecutive calendar years ending immediately prior to
         the calendar year in which occurs the last event that gives Executive
         the right to payments under this Section 10(a); provided, however, that
         if only one bonus is earned by the Executive in the applicable
         three-year period, such bonus shall be deemed to be the Average Annual
         Bonus.

         (b) Gross-Up Payment. If any payment or distribution by the Company or
any of its affiliates, or any acceleration of such payment or vesting of the
stock options or long-term

                                       8
<PAGE>

incentives, with respect to or for the benefit of Executive, whether paid or
payable or distributed or distributable under this Agreement or under any other
agreement, policy, plan, program or arrangement, or the lapse or termination of
any restriction under any agreement, policy, plan, program or arrangement (a
"Payment"), would be subject to the excise tax imposed by Section 4999 of the
Code by reason of being considered contingent on a change in ownership or
control of the Company, with the meaning of Section 280G of the Code, or to any
similar tax imposed by state or local law, or any interest or penalties with
respect to such tax (such tax or taxes, together with any interest or penalties
being hereafter collectively referred to as the "Excise Tax"), then Executive
shall be entitled to receive an additional payment or payments (collectively, a
"Gross-Up Payment"). The Gross-Up Payment will be in an amount such that, after
payment by Executive of all taxes (including any interest or penalties imposed
with respect to such taxes), including any income tax or Excise Tax imposed on
the Gross-Up Payment, Executive retains an amount equal to the Payment before
any Excise Tax is imposed. Any Gross-Up Payment shall be due and payable to the
Executive thirty (30) days prior to the due date of any Excise Tax.

                  (i) Scale-Back Agreement. Notwithstanding the foregoing, if no
         Excise Tax would apply if the aggregate Payments were reduced by three
         percent (3%), then the aggregate Payments shall be reduced by the
         amount necessary to avoid application of the Excise Tax, in such manner
         as the Executive shall direct, and no Gross-Up Payment will be made.

                  (ii) Determination of Parachute Payments or Gross-Up. Any
         determination of the amount of Payments or Gross-Up required to be made
         under this Agreement shall be made in writing by a certified public
         accountant of the Executive's choosing, whose determination shall be
         conclusive and binding upon the Executive and the Company for all
         purposes. For this purpose, the accountant may make reasonable
         assumptions and approximations concerning applicable taxes and may rely
         on reasonable, good faith interpretations concerning the application of
         Sections 280G and 4999 of the Code. The Company and Executive shall
         promptly furnish to the accountant such information and documents as
         the accountant may reasonably request in order to make a determination
         hereunder. The Company shall bear the fees of the accountant and all
         costs the accountant may reasonably incur in connection with any
         calculations contemplated hereunder. The accountant shall be required
         to provide a detailed determination to the Company and the Executive
         within thirty (30) days after the date of receipt of all relevant
         information.

                  (iii) Challenge by the IRS. If federal, state and local income
         or other tax returns filed by Executive are consistent with the
         determination of the accountant under paragraph 4 above, and the
         Internal Revenue Service or any other taxing authority asserts a claim
         or notice of deficiency (referred to in this Section as a "claim")
         against the Executive that, if successful, would require the payment by
         the Executive of an Excise Tax, the Company shall be obligated to make
         the Gross-Up Payment set forth above, provided that the Executive (i)
         notifies the Company within ten (10) business days of the claim; (ii)
         does not pay such claim prior to the earlier of (1) the expiration of
         the thirty (30) calendar-day period following the date on which he
         gives such notice to the Company and (2) the date that any payment of
         amount with respect to such claim is due.

                                       9
<PAGE>

         If the Company notifies Executive in writing prior to the expiration of
         such period that it desires to contest such claim, Executive will:

                           (A)      Provide the Company with any written records
                                    or documents in his or her possession
                                    relating to such claim reasonably requested
                                    by the Company;

                           (B)      Take such action in connection with
                                    contesting such claim as the Company shall
                                    reasonably request in writing from time to
                                    time, including, without limitation,
                                    accepting legal representation with respect
                                    to such claim by an attorney competent in
                                    respect of the subject matter and reasonably
                                    selected by the Company;

                           (C)      Cooperate with the Company in good faith in
                                    order to effectively contest such claim,
                                    which may include the payment of an amount
                                    advanced by the Company and assertion of
                                    claim for refund; and

                           (D)      Permit the Company to participate in any
                                    proceedings relating to such claim;

         provided, however, that the Company will bear and pay directly all
         costs and expenses (including interest and penalties) incurred in
         connection with such contest and will indemnify and hold harmless
         Executive, on an after-tax basis, for and against any Excise Tax or
         income tax, including interest and penalties with respect thereto,
         imposed as a result of such contest and any such payments. If the
         Company directs Executive to pay the tax claimed, or otherwise fails to
         contest the claim as described above, the Company will immediately pay
         to Executive the amount of the deficiency payment claimed by the IRS to
         be due, including, but not limited to, any interest, penalty or Excise
         Tax due on such deficiency (such payments to be collectively referred
         to as the "Deficiency Payment") and shall also pay to the Executive a
         Gross-Up Payment in an amount necessary to pay the income tax liability
         of the Executive on the Deficiency Payment and the Gross-Up Payment.

                  (iv) Dispute Resolution. The Company and Executive agree that
         any dispute regarding the interpretation or enforcement of this
         Agreement shall be decided by confidential, final and binding
         arbitration rather than by litigation in court, trial by jury or other
         forum. Executive and Company agree that in any dispute resolution
         proceedings arising out of this Agreement, the Company shall be
         responsible for all reasonable attorney's fees and costs incurred by
         Executive, not to exceed $50,000 in connection with the resolution of
         the dispute in addition to any other relief granted.

         11. No Mitigation; Limited Offset. The Company agrees that, if
Executive's employment with the Company terminates during the Term, Executive is
not required to seek other employment or to attempt in any way to reduce any
amounts payable to Executive by the Company pursuant to this Agreement. Further,
the amount of any payment or benefit provided for in this Agreement shall not be
reduced by any compensation earned by the Executive as the result of employment
by another employer, by retirement benefits, by offset against any amount

                                       10

claimed to be owed by the Executive to the Company (unless such amount is
evidenced by a promissory note signed by the Executive), or otherwise.

         12. Remedies. With respect to each and every breach or violation or
threatened breach or violation by Employee of Section 9, the Company, in
addition to all other remedies available at law or in equity, including specific
performance of the provisions thereof, shall be entitled to enjoin the
commencement or continuance thereof and may, with notice to Employee, but
without the necessity of posting a bond or otherwise, apply to any court of
competent jurisdiction for entry of an immediate restraining order or
injunction. The Company may pursue any of the remedies described in this Section
12 concurrently or consecutively in any order as to any such breach or
violation, and the pursuit of one of such remedies at any time will not be
deemed an election of remedies or waiver of the right to pursue any of the other
of such remedies.

         13. Severability. The provisions of this Agreement are severable, and
any judicial determination that one or more of such provisions, or any portion
thereof, is invalid or unenforceable shall not affect the validity or
enforceability of any other provisions, or portion thereof, but rather shall
cause this Agreement to first be construed in all respects as if such invalid or
unenforceable provisions, or portions thereof, were modified to terms which are
valid and enforceable; provided, however, that if necessary to render this
Agreement enforceable, it shall be construed as if such invalid or unenforceable
provisions, or portions thereof, were omitted.

         14. Successors. This Agreement is personal to the Executive and shall
not be assignable by the Executive without the prior written consent of the
Company. This Agreement shall inure to the benefit of and be binding upon the
Company and its successors and assigns.

         15. Governing Law. The validity, interpretation and performance of this
Agreement and all rights and obligations of the parties hereunder shall be
governed by and construed under the laws of the State of Texas.

         16. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed, if to
Executive, to the address inserted below the Executive's signature on the final

accordance herewith, except that notice of change of address shall be effective

         17. Amendment. This Agreement may not be amended or modified other than
by a written agreement executed by the parties hereto or their respective
successors, assigns or legal representatives.

         18. Miscellaneous. No waiver by either party hereto at any time of any
breach by the other party hereto of, or of any lack of compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes any other
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter hereof which have been made by either party,
including, without limitation, any employment memorandum, memorandum of
understanding, or severance arrangements. Captions and Section headings in this
Agreement are provided merely for convenience and shall not affect the
interpretation of any of the provisions herein.
