three Business Days' 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 shall be irrevocable and effective only upon receipt by
the Administrative Agent, prepay the outstanding aggregate principal amount of
the Loans in whole, but not in part, provided that (A) interest on the principal
prepaid, accrued to the prepayment date, shall be paid on the prepayment date,
(B) if such prepayment is made on or prior to the second anniversary of the
Closing Date, the premiums payable pursuant to Section 2.06(a)(ii) shall be paid
on the prepayment date and (C) if any prepayment of a LIBOR Loan is made on a
date other than the last day of an Interest Period for such LIBOR Loan, the
Borrower shall also pay any amounts owing pursuant to Section 5.04.

               (ii) In connection with any prepayment under clause (i) above
(other than a prepayment made after the second anniversary of the Closing Date),
the Borrower shall pay a premium of (A) 2.00% of the aggregate principal amount
of the Loans prepaid during the period beginning from the Closing Date to and
including the first anniversary of the Closing Date and (B) 1.00% of the
aggregate principal amount of the Loans prepaid during the period the day after
the first anniversary of the Closing Date to and including the second
anniversary of the Closing Date.

          (b) Mandatory Prepayments.

               (i) Upon Transfers and Issuances of Equity. The Borrower shall,
and shall cause any Subsidiary to, pay an amount equal to (A) 100% of the net
cash proceeds received from any Transfers of the type referred to in Sections
9.17(i), based on the greater of the net book value of the Property sold or the
net proceeds received, provided, that, with respect to net cash proceeds
received from a Transfer permitted under Section 9.17(i), Borrower is not
required to make a prepayment hereunder so long as such proceeds have been
applied to the purchase of replacement Property as described in Section 9.17(i)
or may be otherwise permitted pursuant to Section 9.17(iii), (B) 50% of the
excess net cash proceeds received from any issuance by WCA Corp. of any Debt or
by its Subsidiaries of any Subordinated Debt to the extent that during any
fiscal year of the Borrower such net cash proceeds exceed $30,000,000 in the
aggregate, (C) 50% of the excess net cash proceeds received from any issuance by
WCA Corp. or its Subsidiaries of common stock to the extent that during any
fiscal year of the Borrower such net cash proceeds exceed $65,000,000 in the
aggregate and (D) 100% of the net cash proceeds received from any issuance by
WCA Corp. or its Subsidiaries of equity securities (other than common stock).
Prepayments made pursuant to this clause (ii) shall be applied to the Loans pro
rata. 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.

SECOND LIEN CREDIT AGREEMENT-PAGE 24
<PAGE>
               (ii) Generally. Prepayments permitted or required under this
Section 2.06 shall be without premium or penalty, except as required under
Sections 2.06(a) and 5.04 for prepayment of LIBOR Loans. Any prepayments on the
Loans may not be reborrowed and shall be applied to the Loans pro rata. Together
with any prepayments made hereunder, the accrued interest on the principal
amount so prepaid shall be due and payable on the date of such prepayment.

               (iii) 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
9.17(iv) to promptly prepay the Loans. Notwithstanding the foregoing, the
Borrower may elect to provide cash collateral in lieu of the prepayment required
pursuant to this clause (iii) 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.

          (c) First Lien Payment. Notwithstanding any other provision contained
herein to the contrary, no prepayments permitted pursuant to this Section 2.06
shall be applied to the prepayment of the Loans unless and until (i) all
outstanding amounts under the First Lien Financing have been repaid in full in
cash, (ii) all outstanding letters of credit thereunder have been cash
collateralized and (iii) all outstanding commitments thereunder have been
terminated.

     Section 2.07 Lending Offices. The Loans of each Type made by each Lender
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

                                  ARTICLE III

                       PAYMENTS OF PRINCIPAL AND INTEREST

     Section 3.01 Repayment of Loans.

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

          (b) 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 a rate per annum
equal to, 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 Maximum Rate; provided, however, in the event any Loan is
the Base Rate Loan, then such interest rate per annum shall be equal to the Base
Rate (as in effect from time to time) plus 5.00%, but in no event to exceed the
Maximum Rate.

SECOND LIEN CREDIT AGREEMENT-PAGE 25
<PAGE>
          (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 or under
any Loan Document 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 Required
Second Lien 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 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
Loans on the Termination Date shall be paid on such date.

          (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
under this Agreement 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 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 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

SECOND LIEN CREDIT AGREEMENT-PAGE 26
<PAGE>
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; (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.

     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 Maximum 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.

          (a) Funding by Lenders; Presumption by Administrative Agent. Unless
the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Loan that such Lender will not make available to the
Administrative Agent such Lender's share of such Loan, the Administrative Agent
may assume that such Lender has made such share available on such date in
accordance with Section 2.02(f) and may, in reliance upon such assumption, make
available to the Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Loan available to the
Administrative Agent, then the applicable Lender and the Borrower severally
agree to pay to the Administrative Agent forthwith on demand such corresponding
amount with interest thereon, for each day from and including the date such
amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of a payment to be made by such
Lender, the greater of the Federal Funds Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation and (ii) in the case of a payment to be made by the Borrower, the
interest rate applicable to Base Rate Loans. If the Borrower and such Lender
shall pay such interest to the Administrative Agent for the same or an
overlapping period, the Administrative Agent shall promptly remit to the
Borrower the amount of such interest paid by the Borrower for such period. If
such Lender pays its share of the applicable Loan to the Administrative Agent,
then the amount so paid shall constitute such Lender's Loan included in such
Loan. Any payment by the Borrower shall be without prejudice to any claim the
Borrower may have against a Lender that shall have failed to make such payment
to the Administrative Agent.

          (b) Payments by Borrower; Presumptions by Administrative Agent. Unless
the Administrative Agent shall have received notice from the Borrower prior to
the date on

SECOND LIEN CREDIT AGREEMENT-PAGE 27
<PAGE>
which any payment is due to the Administrative Agent for the account of the
Lenders hereunder that the Borrower will not make such payment, the
Administrative Agent may assume that the Borrower has made such payment on such
date in accordance herewith and may, in reliance upon such assumption,
distribute to the Lenders the amount due. In such event, if the Borrower has not
in fact made such payment, then each of the Lenders severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such
Lender, with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation.

     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 and each of its
respective Affiliates shall have the right and be entitled (after consultation
with the Agents), at its option, to set off and apply any and all deposits
(general or special, time or demand, provisional or final, in whatever currency)
at any time held and other obligations (in whatever currency) at any time owing
by such Lender or any such Affiliate to or for the credit or the account of the
Borrower against any and all of the obligations of the Borrower now or hereafter
existing under this Agreement or any other Loan Document to such Lender,
irrespective of whether or not such Lender shall have made any demand under this
Agreement or any other Loan Document and although such obligations of the
Borrower may be contingent or unmatured or are owed to a branch or office of
such Lender different from the branch or office holding such deposit or
obligated on such indebtedness. The rights of each Lender, and its respective
Affiliates under this Section are in addition to other rights and remedies
(including other rights of setoff) that such Lender or its respective Affiliates
may have. Each Lender agrees to notify the Borrower and the Administrative Agent
promptly after any such setoff and application, provided that the failure to
give such notice shall not affect the validity of such setoff and application.

          (b) If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans or other obligations hereunder resulting in such
Lender's receiving payment of a proportion of the aggregate amount of its Loans
and accrued interest thereon or other such obligations greater than its pro rata
share thereof as provided herein, then the Lender receiving such greater
proportion shall (i) notify the Administrative Agent of such fact, and (ii)
purchase (for cash at face value) participations in the Loans and such other
obligations of the other Lenders, or make such other adjustments as shall be
equitable, so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and other amounts owing them,
provided that:

               (x) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest; and

               (y) the provisions of this paragraph shall not be construed to
apply to (A) any payment made by the Borrower pursuant to and in accordance with
the express terms of this Agreement or (B) any payment obtained by a Lender as
consideration for the assignment of

SECOND LIEN CREDIT AGREEMENT-PAGE 28
<PAGE>
or sale of a participation in any of its Loans to any assignee or participant,
other than to the Borrower or any Subsidiary thereof (as to which the provisions
of this section shall apply).

The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the
Borrower rights of setoff and counterclaim with respect to such participation as
fully as if such Lender were a direct creditor of the Borrower in the amount of
such participation.

                                   ARTICLE V

                                YIELD PROTECTION

     Section 5.01 Increased Costs.

          (a) Increased Costs Generally. If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
deposit, compulsory loan, insurance charge or similar requirement against assets
of, deposits with or for the account of, or credit extended or participated in
by, any Lender (except any reserve requirement reflected in the LIBOR Rate);

               (ii) subject any Lender to any tax of any kind whatsoever with
respect to this Agreement or any LIBOR Loan made by it, or change the basis of
taxation of payments to such Lender in respect thereof (except for Indemnified
Taxes or Other Taxes covered by Section 5.02 and the imposition of, or any
change in the rate of, any Excluded Tax payable by such Lender); or

               (iii) impose on any Lender or the London interbank market any
other condition, cost or expense affecting this Agreement or LIBOR Loans made by
such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation
to make any such Loan), or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or any other
amount) then, upon request of such Lender, the Borrower will pay to such Lender
such additional amount or amounts as will compensate on an after-tax basis such
Lender for such additional costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender determines that any Change in
Law affecting such Lender or any lending office of such Lender or such Lender's
holding company, if any, regarding capital requirements has or would have the
effect of reducing the rate of return on such Lender's capital or on the capital
of such Lender's holding company, if any, as a consequence of this Agreement,
the Commitments of such Lender or the Loans made by such Lender to a level below
that which such Lender or such Lender's holding company could have achieved but
for such Change in Law (taking into consideration such Lender's policies and the
policies of such Lender's holding company with respect to capital adequacy),
then from time to time the Borrower will pay to such Lender such additional
amount or amounts as will

SECOND LIEN CREDIT AGREEMENT-PAGE 29
<PAGE>
compensate on an after-tax basis such Lender or such Lender's holding company
for any such reduction suffered.

          (c) Certificates for Reimbursement. A certificate of a Lender setting
forth the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in clause (a) or (b) of this Section
and delivered to the Borrower shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate
within 10 days after receipt thereof.

          (d) Delay in Requests. Failure or delay on the part of any Lender to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's right to demand such compensation, provided that the Borrower
shall not be required to compensate a Lender pursuant to this Section for any
increased costs incurred or reductions suffered more than nine months prior to
the date that such Lender notifies the Borrower of the Change in Law giving rise
to such increased costs or reductions and of such Lender's intention to claim
compensation therefor (except that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the nine-month period
referred to above shall be extended to include the period of retroactive effect
thereof).

     Section 5.02 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower hereunder or under any other Loan Document shall
be made free and clear of and without reduction or withholding for any
Indemnified Taxes or Other Taxes, provided that if the Borrower shall be
required by applicable law to deduct any Indemnified Taxes (including any Other
Taxes) from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section) the Administrative
Agent or Lender, as the case may be, receives 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 timely pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable
law.

          (b) Payment of Other Taxes by the Borrower. Without limiting the
provisions of clause (a) above, the Borrower shall timely pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent and each Lender, within 10 days after demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable
under this Section) paid by the Administrative Agent or such Lender, as the case
may be, and any penalties, interest and reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes or Other Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority.
A certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender (with a copy to the Administrative Agent), or by the
Administrative Agent on its own behalf or on behalf of a Lender shall be
conclusive absent manifest error.

SECOND LIEN CREDIT AGREEMENT-PAGE 30
<PAGE>
          (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority,
the Borrower shall deliver to the Administrative Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Administrative Agent.

          (e) Status of Lenders. Any Foreign Lender that is entitled to an
exemption from or reduction of withholding tax under the law of the jurisdiction
in which the Borrower is resident for tax purposes, or any treaty to which such
jurisdiction is a party, with respect to payments hereunder or under any other
Loan Document shall deliver to the Borrower (with a copy to the Administrative
Agent), at the time or times prescribed by applicable law or reasonably
requested by the Borrower or the Administrative Agent, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate of withholding. In
addition, any Lender, if requested by the Borrower or the Administrative Agent,
shall deliver such other documentation prescribed by applicable law or
reasonably requested by the Borrower or the Administrative Agent as will enable
the Borrower or the Administrative Agent to determine whether or not such Lender
is subject to backup withholding or information reporting requirements.

     Without limiting the generality of the foregoing, in the event that the
Borrower is resident for tax purposes in the United States of America, any
Foreign Lender shall deliver to the Borrower and the Administrative Agent (in
such number of copies as shall be requested by the recipient) on or prior to the
date on which such Foreign Lender becomes a Lender under this Agreement (and
from time to time thereafter upon the request of the Borrower or the
Administrative Agent, but only if such Foreign Lender is legally entitled to do
so), whichever of the following is applicable:

               (i) duly completed copies of Internal Revenue Service Form W-8BEN
claiming eligibility for benefits of an income tax treaty to which the United
States of America is a party,

               (ii) duly completed copies of Internal Revenue Service Form
W-8ECI,

               (iii) in the case of a Foreign Lender claiming the benefits of
the exemption for portfolio interest under section 881(c) of the Code, (x) a
certificate to the effect that such Foreign Lender is not (A) a "bank" within
the meaning of section 881(c)(3)(A) of the Code, (B) a "10 percent shareholder"
of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a
"controlled foreign corporation" described in section 881(c)(3)(C) of the Code
and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

               (iv) any other form prescribed by applicable law as a basis for
claiming exemption from or a reduction in United States Federal withholding tax
duly completed together with such supplementary documentation as may be
prescribed by applicable law to permit the Borrower to determine the withholding
or deduction required to be made.

          (f) Treatment of Certain Refunds. If the Administrative Agent or a
Lender determines, in its sole judgment, that it has received a refund of any
Taxes or Other Taxes as to

SECOND LIEN CREDIT AGREEMENT-PAGE 31
<PAGE>
which it has been indemnified by the Borrower or with respect to which the
Borrower has paid additional amounts pursuant to this Section, it shall pay to
the Borrower an amount equal to such refund (but only to the extent of indemnity
payments made, or additional amounts paid, by the Borrower under this Section
with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent or such Lender, as the case
may be, and without interest (other than any interest paid by the relevant
Governmental Authority with respect to such refund), provided that the Borrower,
upon the request of the Administrative Agent or such Lender agrees to repay the
amount paid over to the Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent or
such Lender in the event the Administrative Agent or such Lender is required to
repay such refund to such Governmental Authority. This Section shall not be
construed to require the Administrative Agent or any Lender to make available
its tax returns (or any other information relating to its taxes that it deems
confidential) to the Borrower or any other Person.

     Section 5.03 Mitigation Obligations; Replacement of Lenders.

          (a) Designation of a Different Lending Office. If any Lender requests
compensation under Section 5.01, or requires the Borrower to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 5.02, then such Lender shall use reasonable efforts to
designate a different lending office for funding or booking its Loans hereunder
or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section
5.01 or 5.02, as the case may be, in the future and (ii) would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment.

          (b) Replacement of Lenders. If any Lender requests compensation under
Section 5.01, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 5.02, or if any Lender defaults in its obligation to fund Loans
hereunder, then the Borrower may, at its sole expense and effort, upon notice to
such Lender and the Administrative Agent, require such Lender to assign and
delegate, without recourse (in accordance with and subject to the restrictions
contained in, and consents required by, Section 12.05(b)), all of its interests,
rights and obligations under this Agreement and the related Loan Documents to an
assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment), provided that:

               (i) the Borrower shall have paid to the Administrative Agent the
assignment fee specified in Section 12.05(b)(iv);

               (ii) such Lender shall have received payment of an amount equal
to the outstanding principal of its Loans accrued interest thereon, accrued fees
and all other amounts payable to it hereunder and under the other Loan Documents
(including any amounts under Section 5.04) from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts);

SECOND LIEN CREDIT AGREEMENT-PAGE 32
<PAGE>
               (iii) in the case of any such assignment resulting from a claim
for compensation under Section 5.01 or payments required to be made pursuant to
Section 5.02, such assignment will result in a reduction in such compensation or
payments thereafter; and

               (iv) such assignment does not conflict with applicable law.

A Lender shall not be required to make any such assignment or delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

          (c) Time Limited. Notwithstanding anything to the contrary contained
in this Article V, 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 prior to such Lender's giving notice to the Borrower that
such Lender has suffered or incurred such costs or expenses.

          (d) Non Discriminatory Basis. None of the Lenders shall be permitted
to pass through to the Borrower costs and expenses under this Article V 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.

     Section 5.04 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:

          (a) 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

          (b) 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).

                                   ARTICLE VII

                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Agents and the Lenders that
(each representation and warranty herein is given as of the Closing Date):

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

     Section 7.02 Financial Condition. The audited consolidated balance sheet of
WCA Corp. as at December 31, 2004 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 a Registered Public Accounting Firm heretofore
furnished to each of the Lenders, are complete and correct and fairly present
the consolidated financial condition of WCA Corp. and its Consolidated
Subsidiaries as at said dates and the results of its operations for the fiscal
year, all in accordance with GAAP, as applied on a consistent basis. The
unaudited consolidated balance sheet of the Borrower as at March 31, 2005 and
the related consolidated statement of income, stockholders' equity and cash flow
for the portion of the fiscal year ended on such date are complete and correct
and fairly present the consolidated financial condition of the Borrower and its
Consolidated Subsidiaries as at said date, all in accordance with GAAP, as
applied on a consistent basis (subject to normal year-end adjustments). Neither
the Borrower nor any Subsidiary has on the Closing Date any material Debt,
contingent liabilities, liabilities for taxes, forward or long-term commitments
other than those customary in Borrower's business or unrealized or anticipated
losses from any unfavorable commitments, except as referred to or reflected or
provided for in the Financial Statements or in Schedule 7.02. Since March 31,
2005, 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,

SECOND LIEN CREDIT AGREEMENT-PAGE 36
<PAGE>
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. Since the date of the Financial Statements,
no Internal Control Event has occurred.

     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, nor compliance with the terms and provisions hereof will conflict
with or result in a breach of, or require any consent which has not been
obtained as of the Closing Date under, the respective charter or bylaws,
partnership agreement, operating agreement or other organizational documents, as
the case may be, of the Borrower or any Subsidiary, or, in any material respect,
any Governmental Requirement or any material agreement or instrument to which
the Borrower or any Subsidiary is a party or by which it is bound or to which it
or its Properties are subject, or constitute a default under any such agreement
or instrument, or result in the creation or imposition of any material Lien upon
any of the revenues or assets of the Borrower or any Subsidiary pursuant to the
terms of any such agreement or instrument other than the Liens created by the
Loan Documents.

     Section 7.05 Authority. The Borrower and each Subsidiary have all necessary
power (corporate or otherwise) and authority to execute, deliver and perform its
obligations under the Loan Documents to which it is a party; and the execution,
delivery and performance by the Borrower and each Subsidiary of the Loan
Documents to which it is a party, have been duly authorized by all necessary
action (corporate or otherwise) on its part; and the Loan 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 Loan
Documents or for the validity or enforceability thereof, except for the
recording and filing of the Loan Documents as required by this Agreement.

     Section 7.07 Use of Proceeds. The proceeds of the Loans shall be used to
(i) refinance certain existing indebtedness of the Borrower, (ii) pay fees and
expenses incurred in connection with the transactions contemplated hereby, (iii)
provide working capital and general business purpose needs of the Borrower and
the Guarantors (other than the Parent), (iv) the funding of Qualified
Acquisition Expenditures, Expansion Expenditures, and Capital Expenditures
permitted hereunder, and (v) the funding of certain other expenditures approved
by the Administrative Agent from time to time. The Borrower is not engaged
principally, or as one of

SECOND LIEN CREDIT AGREEMENT-PAGE 37
<PAGE>
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, directly or indirectly, to purchase or carry any margin stock.

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

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

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

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

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

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

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

SECOND LIEN CREDIT AGREEMENT-PAGE 38
<PAGE>
          (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 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

clear of all Liens, except Liens permitted by Section 9.02. Material Property
held by the Borrower or its Subsidiaries under leases or similar arrangements
are listed in item 2 of Schedule 7.10.

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

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

     Section 7.11 No Material Misstatements. No written information, statement,
exhibit, certificate, document or report, taken as a whole, furnished to the
Administrative Agent and the Lenders (or any of them) by the Borrower or any
Subsidiary in connection with the negotiation of this Agreement contained any
material misstatement of fact or omitted to state a material fact or any fact
necessary to make the statement contained therein not materially misleading in
the light of the circumstances in which made and with respect to the Borrower
and its Subsidiaries

SECOND LIEN CREDIT AGREEMENT-PAGE 39
<PAGE>
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

"investment company," within the meaning of the Investment Company Act of 1940,

company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," or a "public utility" within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

     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;

SECOND LIEN CREDIT AGREEMENT-PAGE 40
<PAGE>
          (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
and production wastes, if any, generated at any and all Property of the Borrower
or any Subsidiary have in the past been transported, treated and disposed of in
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 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

SECOND LIEN CREDIT AGREEMENT-PAGE 41
<PAGE>
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 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 other Loan Documents, 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

                                   THE AGENTS

     Section 11.01 Appointment and Authority. Each of the Lenders hereby
irrevocably appoints Wells Fargo to act on its behalf as the Administrative
Agent and the Collateral Agent hereunder and under the other Loan Documents and
authorizes the Agents to take such actions on its behalf and to exercise such
powers as are delegated to the Administrative Agent by the terms hereof or
thereof, together with such actions and powers as are reasonably incidental
thereto. The provisions of this Article are solely for the benefit of the
Administrative Agent and the Lenders and neither the Borrower nor any Guarantor
shall have rights as a third party beneficiary of any of such provisions.

     Section 11.02 Rights as a Lender. The Person serving as the Administrative
Agent hereunder shall have the same rights and powers in its capacity as a
Lender as any other Lender and may exercise the same as though it were not the

SECOND LIEN CREDIT AGREEMENT-PAGE 58
<PAGE>
     Section 11.03 Exculpatory Provisions. No Agent shall have any duties or
obligations except those expressly set forth herein and in the other Loan
Documents. Without limiting the generality of the foregoing, each Agent:

          (a) shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing;

          (b) shall not have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the other Loan Documents that such Agent is
required to exercise as directed in writing by the Required Second Lien Lenders
(or such other number or percentage of the Lenders as shall be expressly
provided for herein or in the other Loan Documents), but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the written instructions of the Required Second
Lien Lenders, and such instructions shall be binding upon all Lenders, provided
that no Agent shall be required to take any action that, in its opinion or the
opinion of its counsel, may expose such Agent to liability or that is contrary
to any Loan Document or applicable law; and

          (c) shall not, except as expressly set forth herein and in the other
Loan Documents, have any duty to disclose, and shall not be liable for the
failure to disclose, any information relating to the Borrower or any of its
Affiliates that is communicated to or obtained by the Person serving as an Agent
or any of its Affiliates in any capacity.

No Agent shall be liable for any action taken or not taken by it (i) with the
consent or at the request of the Required Second Lien Lenders (or such other
number or percentage of the Lenders as shall be necessary, or as such Agent
shall believe in good faith shall be necessary, under the circumstances as
provided in Sections 10.02 and 12.04) or (ii) in the absence of its own gross
negligence or willful misconduct. No Agent shall be deemed to have knowledge of
any Default unless and until notice describing such Default is given to such
Agent by the Borrower or a Lender.

     No Agent shall be responsible for or have any duty to ascertain or inquire
into (i) any statement, warranty or representation made in or in connection with
this Agreement or any other Loan Document, (ii) the contents of any certificate,
report or other document delivered hereunder or thereunder or in connection
herewith or therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein or therein
or the occurrence of any Default, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document or any
other agreement, instrument or document or (v) the satisfaction of any condition
set forth in Article VI or elsewhere herein, other than to confirm receipt of
items expressly required to be delivered to such Agent.

     Section 11.04 Reliance by any Agent. Each Agent shall be entitled to rely
upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing
(including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or
otherwise authenticated by the proper Person. Each Agent also may rely upon any
statement made to it orally or by telephone and believed by it to have been made
by the proper Person, and

SECOND LIEN CREDIT AGREEMENT-PAGE 59
<PAGE>
shall not incur any liability for relying thereon. In determining compliance
with any condition hereunder to the making of a Loan that by its terms must be
fulfilled to the satisfaction of a Lender, each Agent may presume that such
condition is satisfactory to such Lender unless such Agent shall have received
notice to the contrary from such Lender prior to the making of such Loan. Each
Agent may consult with legal counsel (who may be counsel for the Borrower),
independent accountants and other experts selected by it, and shall not be
liable for any action taken or not taken by it in accordance with the advice of
any such counsel, accountants or experts.

     Section 11.05 Delegation of Duties. Each Agent may perform any and all of
its duties and exercise its rights and powers hereunder or under any other Loan
Document by or through any one or more sub agents appointed by such Agent. Each
Agent and any such sub agent may perform any and all of its duties and exercise
its rights and powers by or through their respective Related Parties. The
exculpatory provisions of this Article shall apply to any such sub agent and to
the Related Parties of any Agent and any such sub agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as an Agent.

     Section 11.06 Resignation of an Agent. An Agent may at any time give notice
of its resignation to the Lenders and the Borrower. Upon receipt of any such
notice of resignation, the Required Second Lien Lenders shall have the right, in
consultation with the Borrower, to appoint a successor, which shall be a bank
with an office in the United States of America, or an Affiliate of any such bank
with an office in the United States of America. If no such successor shall have
been so appointed by the Required Second Lien Lenders and shall have accepted
such appointment within 30 days after the retiring Agent gives notice of its
resignation, then the retiring Agent may on behalf of the Lenders appoint a
successor Agent meeting the qualifications set forth above provided that if such
Agent shall notify the Borrower and the Lenders that no qualifying Person has
accepted such appointment, then such resignation shall nonetheless become
effective in accordance with such notice and (1) the retiring Agent shall be
discharged from its duties and obligations hereunder and under the other Loan
Documents (except that in the case of any collateral security held by the
Collateral Agent on behalf of the Lenders under any of the Loan Documents, the
retiring Collateral Agent shall continue to hold such collateral security until
such time as a successor Collateral Agent is appointed) and (2) all payments,
communications and determinations provided to be made by, to or through such
Agent shall instead be made by or to each Lender directly, until such time as
the Required Second Lien Lenders appoint a successor Agent as provided for above
in this paragraph. Upon the acceptance of a successor's appointment as such
Agent hereunder, such successor shall succeed to and become vested with all of
the rights, powers, privileges and duties of the retiring (or retired) Agent,
and the retiring Agent shall be discharged from all of its duties and
obligations hereunder or under the other Loan Documents (if not already
discharged therefrom as provided above in this paragraph). The fees payable by
the Borrower to a successor Agent shall be the same as those payable to its
predecessor unless otherwise agreed between the Borrower and such successor.
After the retiring Agent's resignation hereunder and under the other Loan
Documents, the provisions of this Article and Section 12.03 shall continue in
effect for the benefit of such retiring Agent, its sub agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while the retiring Agent was acting as Agent.

     Section 11.07 Non-Reliance on Agents and Other Lenders. Each Lender
acknowledges that it has, independently and without reliance upon any Agent or
any other Lender or any of their Related Parties and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon any Agent or any other Lender or
any of their Related Parties and based on such documents and information as it
shall from time to time deem appropriate, continue to make its own decisions in
taking or not taking action under or based upon this Agreement, any other Loan
Document or any related agreement or any document furnished hereunder or
thereunder.

authorize the Collateral Agent, at its option and in its discretion:

          (a) to release any Lien on any Property granted to or held by the
Collateral Agent under any Loan Document (i) upon termination of the Commitments
and payment in full of all Obligations (other than contingent indemnification
obligations), (ii) that is sold or to be sold as part of or in connection with
any sale permitted hereunder or under any other Loan Document, or (iii) subject
to Section 12.04, if approved, authorized or ratified in writing by the Required
Second Lien Lenders; and

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

     Upon request by the Collateral Agent at any time, the Required Second Lien
Lenders will confirm in writing the Collateral Agent's authority to release its
interest in particular types or items of property, or to release any Guarantor
from its obligations under the Guaranty Agreement pursuant to this Section
11.09.

     Section 11.10 Intercreditor Agreement. Each Lender hereby authorizes the
Agents to execute the Intercreditor Agreement and hereby agrees to be bound by
the Intercreditor Agreement as if it were a party thereto. No Lender may assign
any of its rights or obligations under this Agreement to any other Person unless
such other Person shall have agreed in writing to be bound by the terms of the
Intercreditor Agreement as if such Person were a party thereto.

     Section 11.11 Indemnification. Each of the Lenders and the Agents
(collectively, the "Lender Parties" and individually, a "Lender Party")
severally agrees to indemnify each Agent (to the extent not promptly reimbursed
by the Borrowers) from and against such Lender Party's ratable share (determined
as provided below) of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever that may be imposed on, incurred by, or asserted
against such Agent in any way relating to or arising out of the Loan Documents
or any action taken or omitted by such Agent under the Loan Documents
(collectively, the "Indemnified Costs"); provided, however, that no Lender Party
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from

SECOND LIEN CREDIT AGREEMENT-PAGE 61
<PAGE>
such Agent's gross negligence or willful misconduct as found in a final,
non-appealable judgment by a court of competent jurisdiction. Without limitation
of the foregoing, each Lender Party agrees to reimburse each Agent promptly upon
demand for its ratable share of any costs and expenses (including, without
limitation, reasonable fees and expenses of counsel) payable by the Borrowers
under Section 12.03, to the extent that such Agent is not promptly reimbursed
for such costs and expenses by the Borrowers. In the case of any investigation,
litigation or proceeding giving rise to any Indemnified Costs, this Section
11.11 applies whether any such investigation, litigation or proceeding is
brought by any Lender Party or any other Person.

                                   ARTICLE XII

                                  MISCELLANEOUS

     Section 12.01 Waiver. No failure on the part of any Agent or any Lender to
exercise and no delay in exercising, and no course of dealing with respect to,
any right, power or privilege under any of the Loan Documents shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, power or
privilege under any of the Loan Documents preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The remedies
provided herein are cumulative and not exclusive of any remedies provided by
law.

     Section 12.02 Notices.

          (a) Notices Generally. Except in the case of notices and other
communications expressly permitted to be given by telephone (and except as

herein shall be in writing and shall be delivered by hand or overnight courier
service, mailed by certified or registered mail or sent by telecopier as
follows:

               (i) if to the Borrower or any Guarantor, to it at the address
specified below the Borrower's name on the signature pages hereof;

               (ii) if to an Agent, to it at the address specified below its
name on the signature page hereof; and

               (iii) if to a Lender, to it at its address (or telecopier number)
set forth in its Administrative Questionnaire.

Notices sent by hand or overnight courier service, or mailed by certified or
registered mail, shall be deemed to have been given when received; notices sent
by telecopier shall be deemed to have been given when sent (except that, if not
given during normal business hours for the recipient, shall be deemed to have
been given at the opening of business on the next business day for the
recipient). Notices delivered through electronic communications to the extent
provided in clause (b) below, shall be effective as provided in said clause (b).

          (b) Electronic Communications. (i) Notices and other communications to
the Lenders hereunder may be delivered or furnished by electronic communication
(including e-mail and Internet or intranet websites) pursuant to procedures
approved by the Administrative Agent, provided that the foregoing shall not
apply to notices to any Lender pursuant to Article II if such

SECOND LIEN CREDIT AGREEMENT-PAGE 62
<PAGE>
Lender has notified the Administrative Agent that it is incapable of receiving
notices under such Article by electronic communication. The Administrative Agent
or the Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to
procedures approved by it, provided that approval of such procedures may be
limited to particular notices or communications.

               (ii) Unless the Administrative Agent otherwise prescribes, (A)
notices and other communications sent to an e-mail address shall be deemed
received upon the sender's receipt of an acknowledgement from the intended
recipient (such as by the "return receipt requested" function, as available,
return e-mail or other written acknowledgement), provided that if such notice or
other communication is not sent during the normal business hours of the
recipient, such notice or communication shall be deemed to have been sent at the
opening of business on the next business day for the recipient, and (B) notices
or communications posted to an Internet or intranet website shall be deemed
received upon the deemed receipt by the intended recipient at its e-mail address
as described in the foregoing clause (A) of notification that such notice or
communication is available and identifying the website address therefor.

               (iii) The Borrower agrees that any Agent may make any material
delivered by the Borrower to such Agent, as well as any amendments, waivers,
consents, and other written information, documents, instruments and other
materials relating to the Parent, the Borrower, any of its Subsidiaries, or any
other materials or matters relating to this Agreement, the other Loan Documents
or any of the transactions contemplated hereby (collectively, the
"Communications") available to the Lenders by posting such notices on an
electronic delivery system (which may be provided by an Agent, an Affiliate of
an Agent, or any Person that is not an Affiliate of an Agent), such as
IntraLinks, or a substantially similar electronic system (the "Platform"). The
Borrower acknowledges that (A) the distribution of material through an
electronic medium is not necessarily secure and that there are confidentiality
and other risks associated with such distribution, (B) the Platform is provided
"as is" and "as available" and (C) neither any Agent nor any of its Affiliates
warrants the accuracy, completeness, timeliness, sufficiency, or sequencing of
the Communications posted on the Platform. Each Agent and its Affiliates
expressly disclaim with respect to the Platform any liability for errors in
transmission, incorrect or incomplete downloading, delays in posting or
delivery, or problems accessing the Communications posted on the Platform and
any liability for any losses, costs, expenses or liabilities that may be
suffered or incurred in connection with the Platform. No warranty of any kind,
express, implied or statutory, including, without limitation, any warranty of
merchantability, fitness for a particular purpose, non-infringement of third
party rights or freedom from viruses or other code defects, is made by any Agent
or any of its Affiliates in connection with the Platform.

               (iv) Each Lender agrees that notice to it specifying that any
Communication has been posted to the Platform shall for purposes of this
Agreement constitute effective delivery to such Lender of such information,
documents or other materials comprising such Communication. Each Lender agrees
(A) to notify, on or before the date such Lender becomes a party to this
Agreement, each Agent in writing of such Lender's e-mail address to which a
notice may be sent (and from time to time thereafter to ensure that each Agent
has on record an effective e-mail address for such Lender) and (B) that any
notice may be sent to such e-mail address.

          (c) Change of Address, Etc. Any party hereto may change its address or
telecopier number for notices and other communications hereunder by notice to
the other parties hereto.

     Section 12.03 Payment of Expenses, Indemnities, etc.

          (a) The Borrower agrees:

               (i) whether or not the transactions hereby contemplated are
consummated, to pay all reasonable expenses of each Agent in the administration
(both before and after the execution hereof and including reasonable fees and
related expenses for advice of counsel for each Agent as to the rights and
duties of the Agents and the Lenders with respect thereto) of, and in connection
with the negotiation, syndication, investigation, preparation, execution and
delivery of, recording or filing of, preservation of rights under, enforcement
of, and refinancing, renegotiation or restructuring of, the Loan Documents and
any amendment, waiver or consent relating thereto (including, without
limitation, travel, photocopy, mailing, courier, telephone and other similar
expenses of the Agents, the cost of environmental audits (including those
conducted in connection with the First Lien Financing) not to exceed $50,000 per
fiscal year unless any audit discloses environmental problems that in any
Agent's reasonable determination requires additional study, in which case the
$50,000 cap shall not apply, surveys and appraisals at reasonable intervals, the
reasonable fees and disbursements of counsel and other outside consultants for
any Agent and, in the case of workout or enforcement after an Event of Default,
the reasonable fees and disbursements of counsel for any Agent and any of the
Lenders); and promptly reimburse each Agent for all amounts expended, advanced
or incurred by the Agents or the Lenders to satisfy any obligation of the
Borrower under this Agreement or any other Loan Document, including without
limitation, all costs and expenses of foreclosure;

               (ii) to indemnify each Agent and each Lender and each of their
Affiliates and each of their Related Parties ("Indemnified 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 designated a party thereto)
as a result of, arising out of or in any way related to (i) any actual or
proposed use by the Borrower of the proceeds of any of the Loans, (ii) the
execution, delivery and performance of the Loan Documents, (iii) the operations
of the business of the Borrower and its Subsidiaries, (iv) the failure of the
Borrower or any Subsidiary to comply with the terms of any Loan Document or this
Agreement, or with any Governmental Requirement, (v) any inaccuracy of any
representation or any breach of any warranty of the Borrower or any Guarantor
set forth in any of the Loan Documents, (vi) any assertion that the Lenders were
not entitled to receive the proceeds received pursuant to the Loan Documents or
(vii) any other aspect of the Loan Documents, including, without limitation, the
reasonable fees and disbursements of counsel and all other reasonable expenses
incurred in connection with investigating, defending or preparing to defend any
such action, suit, proceeding (including any investigations, litigation or
inquiries) or claim and including all Indemnity 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
any Agent or a Lender's shareholders against an Agent or Lender or by reason of
the gross negligence or willful misconduct on the part of any Indemnified Party;
and

SECOND LIEN CREDIT AGREEMENT-PAGE 64
<PAGE>
               (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, including without
limitation, the treatment or disposal of hazardous substances on any of their
Properties, (ii) as a result of the breach or non-compliance by the Borrower or
any Subsidiary with any Environmental Law applicable to the Borrower or any
Subsidiary, (iii) due to past ownership by the Borrower or any Subsidiary of any
of their Properties or past activity on any of their Properties which, though
lawful and fully permissible at the time, could result in present liability,
(iv) the presence, use, release, storage, treatment or disposal of hazardous
substances on or at any of the Properties owned or operated by the Borrower or
any Subsidiary, or (v) any other environmental, health or safety condition in
connection with the Loan Documents; provided, however, no indemnity or hold
harmless protection shall be afforded under this Section 12.03(a)(iii) in
respect of any Property for any occurrence arising from the acts or omissions of
any 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 12.03.

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

          (d) Except as expressly provided in the proviso to Section
12.03(a)(iii) 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 12.03 shall survive
any termination of this Agreement and the payment of the Obligations and shall
continue thereafter in full force and effect.

SECOND LIEN CREDIT AGREEMENT-PAGE 65
<PAGE>
          (f) The Borrower shall pay any amounts due under this Section 12.03
within 30 days of the receipt by the Borrower of notice of the amount due.

     Section 12.04 Amendments, Etc. No amendment or waiver of any provision of
this Agreement or any other Loan Document, nor consent to any departure by any
of the Borrower or any Guarantor therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Required Second Lien
Lenders, the Borrower, the Guarantors (if applicable) and the Agents, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given; provided, however, that (a) no amendment,
waiver or consent shall, unless in writing and signed by all of the Lenders, do
any of the following at any time: (i) waive any of the conditions specified in
Section 6.01, (ii) change the number of Lenders or the percentage of (y) the
Commitment or (z) the aggregate unpaid principal amount of the Loans, (iii)
release all or substantially all of the Borrower's liabilities with respect to
the Obligations owing to the Agents and the Lenders or release any Guarantor
from its obligations under the Guaranty Agreement (except in connection with a
transaction permitted by Section 9.17), (iv) release all or a material portion
of the collateral in any transaction or series of related transactions, (v)
amend Section 4.05 or this Section 12.04 or the definition of "Required Second
Lien Lenders" or (vi) limit the liability of the Borrower or any Guarantor under
any of the Loan Documents and (b) no amendment, waiver or consent shall, unless
in writing and signed by the Required Second Lien Lenders and each Lender
directly affected by such amendment, waiver or consent, (i) increase the
Commitments of such Lender, (ii) reduce or forgive the principal of, or interest
on, any Loan made by such Lender or any fees or other amounts payable hereunder
to such Lender, or (iii) other than Section 2.06, postpone any date (including
the Termination Date) fixed for any payment of principal of, or interest on, any
Loan made by such Lender or any fees or other amounts payable hereunder to such
Lender; provided further that no amendment, waiver or consent shall, unless in
writing and signed by the respective Agent in addition to the Lenders required
above to take such action, affect the rights or duties of such Agent under this
Agreement or the other Loan Documents.

     Section 12.05 Successors and Assigns.

          (a) Successors and Assigns Generally. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that the Borrower may
not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of the Administrative Agent and each Lender
and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an Eligible Assignee in accordance with the provisions
of clause (b) of this Section, (ii) by way of participation in accordance with
the provisions of clause (d) of this Section or (iii) by way of pledge or
assignment of a security interest subject to the restrictions of clause (f) of
this Section (and any other attempted assignment or transfer by any party hereto
shall be null and void). Nothing in this Agreement, expressed or implied, shall
be construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby, Participants to the extent
provided in clause (d) of this Section and, to the extent expressly contemplated
hereby, the Related Parties of each of the Administrative Agent and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

SECOND LIEN CREDIT AGREEMENT-PAGE 66
<PAGE>
          (b) Assignments by Lenders. Any Lender may at any time assign to one
or more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it); provided that

               (i) except in the case of an assignment of the entire remaining
amount of the assigning Lender's Commitment and the Loans at the time owing to
it or in the case of an assignment to a Lender or an Affiliate of a Lender or an
Approved Fund with respect to a Lender, the aggregate amount of the Commitment
(which for this purpose includes Loans outstanding thereunder) or, if the
applicable Commitment is not then in effect, the principal outstanding balance
of the Loans of the assigning Lender subject to each such assignment (determined
as of the date the Assignment and Assumption substantially in the form of
Exhibit C attached hereto (the "Assignment") with respect to such assignment is
delivered to the Administrative Agent or, if "Trade Date" is specified in the
Assignment, as of the Trade Date) shall not be less than $1,000,000, unless each
of the Administrative Agent and, so long as no Default has occurred and is
continuing, the Borrower otherwise consent (each such consent not to be
unreasonably withheld or delayed);

               (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loan or the Commitment assigned, except that
this clause (ii) shall not prohibit any Lender from assigning all or a portion
of its rights and obligations among separate tranches on a non-pro rata basis;

               (iii) any assignment of a Commitment must be approved by the
Administrative Agent unless the Person that is the proposed assignee is itself a
Lender with a Commitment (whether or not the proposed assignee would otherwise
qualify as an Eligible Assignee); and

               (iv) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment, together with a processing and
recordation fee of $3,500, and the Eligible Assignee, if it shall not be a
Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire; provided however, that no such processing and recordation fee
described in this clause (iv) shall be due if the Eligible Assignee is either an
Affiliate of the assigning Lender or is a Lender prior to such assignment.

Subject to acceptance and recording thereof by the Administrative Agent pursuant
to clause (c) of this Section, from and after the effective date specified in
each Assignment, the Eligible Assignee thereunder shall be a party to this
Agreement and, to the extent of the interest assigned by such Assignment, have
the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment, be released from its obligations under this Agreement (and, in the
case of an Assignment covering all of the assigning Lender's rights and
obligations under this Agreement, such Lender shall cease to be a party hereto)
but shall continue to be entitled to the benefits of Article V and Section 12.03
with respect to facts and circumstances occurring prior to the effective date of
such assignment. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this paragraph shall be treated
for purposes of this

SECOND LIEN CREDIT AGREEMENT-PAGE 67
<PAGE>
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with clause (d) of this Section.

          (c) Register. The Administrative Agent, acting solely for this purpose
as an agent of the Borrower, shall maintain at one of its offices in Denver,
Colorado a copy of each Assignment delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary.

          (d) Participations. Any Lender may at any time, without the consent
of, or notice to, the Borrower or the Administrative Agent, sell participations
to any Person (other than a natural person or the Borrower or any of the
Borrower's Affiliates or Subsidiaries ) (each, a "Participant") in all or a
portion of such Lender's rights and/or obligations under this Agreement
(including all or a portion of its Commitment and/or the Loans owing to it);
provided that (i) such Lender's obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Borrower, the
Administrative Agent and the Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender's rights and obligations under
this Agreement.

     Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, modification or waiver with respect to the following:
extending the final maturity of the Loans, 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, or reduces
the interest rate applicable to the Loans or the fees payable to the Lenders
generally, described in Section 12.04(i) that affects such Participant. Subject
to clause (e) of this Section, the Borrower agrees that each Participant shall
be entitled to the benefits of Article V to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to clause (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 12.13 as though it were a Lender, provided
such Participant agrees to be subject to Section 4.05 as though it were a
Lender.

          (e) Limitations upon Participant Rights. A Participant shall not be
entitled to receive any greater payment under Section 5.01 and 5.02 than the
applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to
such Participant is made with the Borrower's prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 5.02 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the
benefit of the Borrower, to comply with Section 5.02(e) as though it were a
Lender.

SECOND LIEN CREDIT AGREEMENT-PAGE 68
<PAGE>
          (f) Certain Pledges. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to
secure obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

          (g) Dissenting Lenders. In the event that the Borrower shall request
that the Lender Parties enter into any amendment, modification, consent or
waiver with respect to this Agreement or any other Loan Document, and any Lender
Party elects not to enter into such amendment, modification, consent or waiver
(each such Lender Party being a "Dissenting Lender"), then the Borrower shall
have the right upon 10 days' written notice to the Administrative Agent and such
Dissenting Lender, to require (so long as the Administrative Agent consents
thereto) each such Dissenting Lender to assign 100% of the rights and
obligations of the Dissenting Lender at par to any Lender Party or any other
financial institution which satisfies the requirements of Section 12.05(b) and
has been consented to by the Administrative Agent. Each such assignment shall be
made pursuant to an Assignment and shall comply with the other terms of this
Section 12.05. The Borrower shall pay, and/or cause such relevant assignee to
pay, to such Dissenting Lender, concurrently with the effectiveness of each such
assignment, any amounts payable under this Agreement that would have been
payable if the Borrower had voluntarily prepaid such Loans. The Dissenting
Lender shall not be required to pay any fee relating to such assignment.

     Section 12.06 Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents 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 this Agreement or any
other Loan Document.

     Section 12.07 Counterparts, etc.

          (a) Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and the other
Loan Documents, and any separate letter agreements with respect to fees payable
to the Administrative Agent, constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. Except as provided in Section 6.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof that, when
taken together, bear the signatures of each of the other parties hereto.
Delivery of an executed counterpart of a signature page of this Agreement by
telecopy shall be effective as delivery of a manually executed counterpart of
this Agreement.

          (b) Electronic Execution of Assignments. The words "execution,"
"signed," "signature," and words of like import in any Assignment shall be
deemed to include electronic signatures or the keeping of records in electronic
form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in
any applicable

SECOND LIEN CREDIT AGREEMENT-PAGE 69
<PAGE>
law, including the Federal Electronic Signatures in Global and National Commerce
Act, the New York State Electronic Signatures and Records Act, or any other
similar state laws based on the Uniform Electronic Transactions Act.

     Section 12.08 Survival. The obligations of the parties under Article V and
Section 12.03 shall survive the repayment of the Loans. 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 Agents' and the Lenders' Liens, security
interests, rights, powers and remedies under this Agreement and each other Loan
Document effective immediately prior thereto shall continue in full force and
effect. In such event, each such Loan Document shall be automatically reinstated
and the Borrower shall take such action as may be reasonably requested by the
Agents and the Lenders to effect such reinstatement.

     Section 12.09 Captions. Captions and section headings appearing herein are
included solely for convenience of reference and are not intended to affect the
interpretation of any provision of this Agreement.

     Section 12.10 Governing Law; Submission to Jurisdiction.

          (a) Governing Law. This Agreement shall be governed by, and construed
in accordance with, the law of the State of New York.

          (b) Submission to Jurisdiction. The Borrower irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the courts of the State of New York or Federal Court of the
United States of America sitting in the Borough of Manhattan, New York City, and
any appellate court from any thereof, in any action or proceeding arising out of
or relating to this Agreement or any other Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State court or, to the
fullest extent permitted by applicable law, in such Federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement or in
any other Loan Document shall affect any right that any Agent or any Lender may
otherwise have to bring any action or proceeding relating to this Agreement or
any other Loan Document against the Borrower or its properties in the courts of
any jurisdiction.

          (c) Waiver of Venue. The Borrower irrevocably and unconditionally
waives, to the fullest extent permitted by applicable law, any objection that it
may now or hereafter have to the laying of venue of any action or proceeding
arising out of or relating to this Agreement or any other Loan Document in any
court referred to in clause (b) of this Section. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by applicable law,
the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

          (d) Service of Process. Each party hereto irrevocably consents to
service of process in the manner provided for notices in Section 12.02. Nothing
in this Agreement will affect the right of any party hereto to serve process in
any other manner permitted by applicable law.

     Section 12.11 Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section 12.11 shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Rate to the date of repayment, shall
have been received by such Lender.

     Section 12.12 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO RELATED PARTY OF ANY OTHER
PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     Section 12.13 Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its respective Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
applicable law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final, in whatever currency) at any time held and
other obligations (in whatever currency) at any time owing by such Lender or any
such Affiliate to or for the credit or the account of the Borrower against any
and all of the obligations of the Borrower now or hereafter existing under this
Agreement or any other Loan Document to such Lender, irrespective of whether or
not such Lender shall have made any demand under this Agreement or any other
Loan Document and although such obligations of the Borrower may be contingent or
unmatured or are owed to a branch or office of such Lender different from the
branch or office holding such deposit or obligated on such indebtedness. The
rights of each Lender and its respective Affiliates under this Section are in
addition to other rights and remedies (including other rights of setoff) that
such Lender or its respective Affiliates

SECOND LIEN CREDIT AGREEMENT-PAGE 71
<PAGE>
may have. Each Lender agrees to notify the Borrower and the Agents promptly
after any such setoff and application, provided that the failure to give such
notice shall not affect the validity of such setoff and application.

     Section 12.14 Confidentiality.

          (a) Each of the Agents and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its Affiliates and to its and its Affiliates' Related
Parties (it being understood that the Persons to whom such disclosure is made
will be informed of the confidential nature of such Information and instructed
to keep such Information confidential), (b) to the extent requested by any
regulatory authority purporting to have jurisdiction over it (including any
self-regulatory authority, such as the National Association of Insurance
Commissioners), (c) to the extent required by applicable laws or regulations or
by any subpoena or similar legal process, (d) to any other party hereto, (e) in
connection with the exercise of any remedies hereunder or under any other Loan
Document or any action or proceeding relating to this Agreement or any other
Loan Document or the enforcement of rights hereunder or thereunder, (f) subject
to an agreement containing provisions substantially the same as those of this
Section, to (i) any pledgee under Section 12.05(f) or any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
the Borrower and its obligations, (g) with the consent of the Borrower, (h) to a
Person that is an investor or prospective investor in a securitization that
agrees that its access to Information is solely for purposes of evaluating an
investment in such permitted securitization and who agrees to treat such
information as confidential, (i) to a person that is a trustee, collateral
manager, servicer, backup servicer, noteholder or other security holder, secured
party or other participant in a securitization in connection with the
administration, servicing and reporting on the assets serving as collateral for
a securitization and who agrees to treat such information as confidential, (j)
to a nationally recognized rating agency that requires access to information
regarding the Borrower or any of its Subsidiaries and the Loans for the purpose
of issuing ratings in connection with a securitization or (k) to the extent such
Information (x) becomes publicly available other than as a result of a breach of
this Section or (y) becomes available to any Agent, any Lender, or any of their
respective Affiliates on a nonconfidential basis from a source other than the
Borrower.

          (b) For purposes of this Section, "Information" means all information
received from the Borrower or any of its Subsidiaries relating to the Borrower
or any of its Subsidiaries or any of their respective businesses, other than any
such information that is available to any Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower or any of its
Subsidiaries, provided that, in the case of information received from the
Borrower or any of its Subsidiaries after the date hereof, such information is
clearly identified at the time of delivery as confidential. Any Person required
to maintain the confidentiality of Information as provided in this Section shall
be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

     Section 12.15 Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the other Loan
Documents and agrees that it is charged

SECOND LIEN CREDIT AGREEMENT-PAGE 72
<PAGE>
with notice and knowledge of the terms of this Agreement and the other Loan
Documents; 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 other Loan Documents; and has received the advice of its attorney in
entering into this Agreement and the other Loan Documents; and that it
recognizes that certain of the terms of this Agreement and the other Loan
Documents 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 other Loan Documents on the basis that the party had no notice or knowledge
of such provision or that the provision is not "conspicuous."

     Section 12.16 USA Patriot Act Notice. Each Lender and the Agents (for
itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of The Uniting and Strengthening America by
Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of
2001 (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 Agents, as applicable,
to identify the Borrower in accordance with the Act.

SECOND LIEN CREDIT AGREEMENT-SCHEDULE 1.2

                                 SCHEDULE 7.02

                              FINANCIAL CONDITION

1.   The Borrower and its Subsidiaries are obligors in respect of (a) bonds,
     surety agreements and suretyship obligations imposed by regulatory
     authorities in connection with closure and post-closure obligations with
     regard to landfills owned or operated by them; (b) performance bonds under
     municipal hauling contracts; and (c) other similar suretyship and bonding
     arrangements customary in their business.

2.   The Borrower and its Subsidiaries from time to time enter into contracts
     and arrangements in which they agree to perform services at rates that are
     less than the normal rates they receive for such services, and may from
     time to time result in operations losses, in connection with other
     activities as to which they expect to receive a compensating benefit. For
     example, they may enter into hauling contracts at a low margin in the
     expectation that performance on the hauling contract will result in
     increased amounts of waste being disposed of at favorable disposal rates at
     landfills owned by the Borrower or its Subsidiaries; the Borrower and its
     Subsidiaries may also from time to time grant favorable landfill disposal
     rates to haulers in exchange for reciprocal privileges at other landfills
     not owned by the Borrower or its Subsidiaries. The Borrower makes no
     representation herein as to whether any particular contract or commitment,
     viewed in isolation, would not result in an unanticipated loss or would
     not, standing alone, constitute an "unfavorable commitment." In addition,
     the Borrower and its Subsidiaries also are parties to hauling and
     collection agreements that do not provide for escalation of fees in the
     event fuel costs or other operating costs increase over the term of the
     agreement.

                                  SCHEDULE 7.03

                                   LITIGATION

     There are no lawsuits pending against Borrower or, to the knowledge of the
Borrower, threatened against the Borrower.

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

                              ENVIRONMENTAL MATTERS

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