         Section 2.02 Fees.

                 (a)  Administrative Fee. Until the Loans are repaid in full,

Rate (as applicable), with the first such installment plus interest at the Base
Rate being due on September 19, 2002, and the second, third and fourth
installments being due on December 19, 2002, March 19, 2003, and June 19, 2003
respectively. The Restructuring Fee shall be fully earned by the Lenders as of
the Closing Date.

                 (c)  Financing Fee. In partial consideration of the waiver of
defaults under the Existing Agreement granted under Section 2.02(b) above and in
order to induce Lenders to agree to the restructuring, modification and
continuation of the Prior Debt as contemplated hereby, the Borrower shall pay to
the Agent for the account of each Lender a Financing Fee in the amount of
$1,897,139.15 being 4% of the Restructured Amount (the "Financing Fee"), which
Financing Fee shall be payable in full without interest on the Final Maturity
Date. The Financing Fee shall be fully earned by the Lenders as of the Closing
Date. The Financing Fee shall be discounted as provided in Schedule 2.02(c) to
this Agreement if the aggregate principal amount of the Loans is reduced to the
amounts, and by the dates, specified therein.

         Section 2.03 Notes. The Loan of each Lender shall be evidenced by a
single replacement promissory note of the Borrower in substantially the form of
Exhibit A, dated (i) the Closing Date or (ii) the effective date of an
Assignment pursuant to Section 12.06(b), payable to the order of such Lender in
a principal amount equal to its Maximum Credit Amount as originally in effect
and otherwise duly completed and such substitute Notes as required by Section
12.06(b). The date and amount of each Lender's Loan and all payments made on
account of the principal thereof, shall be recorded by such Lender on its books,
and, prior to any transfer, may be endorsed by such Lender on the schedule
attached to such Notes or any continuation thereof or on any separate record
maintained by such Lender. Failure to make any such notation or to attach a
schedule shall not affect any Lender's or the Borrower's rights or obligations
in respect of such Loan or affect the validity of such transfer by any Lender of
its Note.

of the prepayment (which shall be at least $10,000 or the remaining aggregate
principal balance outstanding on the Notes) and shall be irrevocable and
effective only upon receipt by the Agent. As a condition to any optional
prepayment, interest on the principal prepaid, accrued to the prepayment date,
shall be paid on the prepayment date.

                 (b)  Notwithstanding the foregoing, if the Borrower should
voluntarily prepay the Loans in their entirety, Borrower shall pay to the Agent,
for the benefit of the Lenders the then unpaid amount of the Restructuring Fee
plus accrued and unpaid interest thereon and the Financing Fee as discounted in
accordance with Schedule 2.02(c).

The final payment of the remaining principal balance of the Notes and any other
amounts owing on the Loans and not previously paid shall be due on the Final
Maturity Date.

                 (b)  Mandatory Prepayments.

                      (i)   Upon receipt by the Borrower or any of its
         Subsidiaries, the Borrower shall prepay the Loans in an amount equal to
         50% of the cash proceeds (net of underwriting discounts and commissions
         or underwriting or placement fees, investment banking fees, legal fees,
         accounting fees, and other customary fees, commissions, expenses and
         costs associated therewith and net of taxes paid or payable as a result
         thereof) of any sale of equity securities by the Borrower or any of its
         Subsidiaries; provided, however, that no such prepayment shall be
         required with respect to any equity securities issued by any Subsidiary
         of the Borrower to the Borrower or another Subsidiary of the Borrower.

                      (ii)  Commencing  with the 12 month period ended  March
         31, 2003, the Borrower shall prepay the Loans in an amount equal to the
         Excess Cash Flow Percentage of the Excess Cash Flow (the "Annual Cash
         Flow Payment") as follows:

                      (A)   On or prior to April 30 of each year, the Borrower
                 shall pay the Annual Cash Flow Payment in full, except that if,
                 after giving effect to such payment, Borrower's Cash on Hand on
                 the date of such payment would be less than $3,000,000 (such
                 amount being referred to herein as the "Cash Floor Limit"), the
                 Borrower may defer payment of such portion of the Annual Cash
                 Flow Payment as is necessary to maintain the Cash Floor Limit
                 as provided below; and

                      (B)   For so long as any portion of the Annual Cash Flow
                 Payment remains unpaid as provided above, then on the last
                 Business Day of each successive month the Borrower shall pay
                 the deferred portion (if any) of the Annual Cash Flow Payment
                 in full, except that if, after giving effect to such payment,
                 Borrower's Cash on Hand on the date of such payment would be
                 less than the Cash Floor Limit, then the Borrower may further
                 defer to the next month payment of such portion of the Annual
                 Cash Flow Payment as is necessary to maintain the Cash Floor
                 Limit.

                                       17

<PAGE>

                      (iii) Upon any (A) Event of Loss resulting in Net Proceeds
         of $25,000 or more with respect to which Borrower (or its Subsidiaries)
         have determined not to repair or replace the Property which is the
         subject of the Event of Loss, or (B) sale or series of related sales of
         assets by the Borrower or any of its Subsidiaries undertaken pursuant
         to Section 9.09(b) or as otherwise permitted by a waiver by the Lenders
         to this Agreement, the Borrower shall prepay the Loans in an amount
         equal to 100% of the Net Proceeds of (y) each such Event of Loss, or
         (z) each such sale, in each case, if and to the extent that Net
         Proceeds received by the Borrower or its Subsidiaries from such sale or
         series of related sales of assets exceeds $100,000 in the aggregate for
         all such sales in any fiscal year.

                      (iv)  Prepayments of the Loans pursuant to this Section
         3.02(b) shall be applied to the principal amounts outstanding on the
         Loans in inverse order of maturity.

         Section 3.03 Interest.

                 (a)  Interest Rates. The Borrower will pay to the Agent, for
the account of each Lender, interest on the unpaid principal amount of each Loan
for the period commencing on the Closing Date, but excluding the date such Loan
shall be paid in full, at a rate per annum equal to the Base Rate (as in effect
from time to time), but in no event to exceed the Highest Lawful Rate.

                 (b)  Post-Default Rate. Notwithstanding the foregoing, the
Borrower will pay to the Agent, for the account of each Lender, interest at the
Post-Default Rate on any principal of any Loan, and (to the fullest extent
permitted by law) on any other amount payable by the Borrower hereunder, under
any Loan Document or under any Note held by such Lender to or for account of
such Lender, for the period commencing on the date of an Event of Default and
ending when such Event of Default and all other Events of Default are cured or
waived.

                 (c)  Deferred Interest Rate. In addition to the Base Rate and
(if applicable) the Post-Default Rate and subject at all times to Section 12.14
hereof , the outstanding principal balance of each Loan shall accrue additional
interest from the Closing Date until paid at the rate of 4 1/2% per annum
("Deferred Interest Rate"). All accrued interest at the Deferred Interest Rate
("Deferred Interest") shall be immediately due and payable only upon the
occurrence of a Payment Default and shall continue to accrue and will be payable
as it accrues for all periods following any Payment Default until paid in full.
If a Payment Default has not occurred prior to July 19, 2005, and the
Indebtedness is paid in full on or prior to July 19, 2005, then (i) no Deferred
Interest shall ever become due or payable and (ii) all accrued and unpaid
Deferred Interest shall be deemed extinguished and forgiven. If the Loans are
accelerated in accordance with Section 10.02(a), but no Payment Default has
occurred concurrently therewith or prior thereto, so long as Borrower continues
to make the regularly scheduled payments required under this Agreement with
respect to the Loans as though no such acceleration had occurred, then Deferred
Interest shall not become due and payable. Notwithstanding any provision herein
to the contrary, the total amounts due to all Lenders for Deferred Interest
shall not exceed $4,500,000.

                 (d)  Due Dates. Accrued interest on the Loans at the Base Rate
shall be payable monthly in arrears commencing on August 1, 2002, and on each
Monthly Date

                                       18

<PAGE>

thereafter. All interest hereunder at the Post-Default Rate shall be payable
from time to time on demand. Deferred Interest shall be payable as provided in
Section 3.03(c).

                 (e)   Determination of Rates. Promptly after the determination
of any interest rate provided for herein or any change therein, the Agent shall
notify the Lenders to which such interest is payable and the Borrower thereof.
Each determination by the Agent of an interest rate or fee hereunder shall,
except in cases of manifest error, be final, conclusive and binding on the
parties. Anything herein to the contrary notwithstanding, the obligations of the
Borrower to any Lender hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder to the extent (but only to the extent) that contracting for,
charging, reserving, collecting or receiving such payment by such Lender would
be contrary to the provisions of any law applicable to such Lender limiting the
Highest Lawful Rate of interest that may be contracted for, charged, reserved,
collected or received by such Lender, and in such event the Borrower shall pay
such Lender interest at the Highest Lawful Rate.

                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, the Notes shall be made in Dollars, in immediately
available funds, to the Agent at such account as the Agent shall specify by
notice to the Borrower from time to time, not later than 11:00 a.m. Dallas 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 Agent under this Agreement or any Note for account of a
Lender shall be paid promptly to such Lender in immediately available funds. If
the due date of any payment under this Agreement or any Note would otherwise
fall on a day which is not a Business Day such date shall be extended to the
next succeeding Business Day and interest shall be payable for any principal so
extended for the period of such extension.

         Section 4.02  Pro Rata Treatment. Except to the extent otherwise
provided herein each Lender agrees that: (i) each payment of the Restructuring
Fee, the Financing Fee or other fees under Section 2.02 shall be made for
account of 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. All computations of interest for the Loans
and fees hereunder shall be made on the basis of a year of 365 or 366 days, as
the case may be, and actual days elapsed. Each determination of an interest rate
by the Agent shall be conclusive and binding on the Borrower and the Lenders in
the absence of manifest error.

                                       19

<PAGE>

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

         Section 4.05   Set-off, Sharing of Payments, Etc.

                 (a)    Upon the occurrence and during the continuance of an
Event of Default, the Borrower agrees that, in addition to (and without
limitation of) any right of set-off, bankers' lien or counterclaim a Lender may
otherwise have, each Lender shall have the right and be entitled (after
consultation with the Agent), at its option, to offset balances held by it or by
any of its Affiliates for account of the Borrower or any Subsidiary at any of
its offices, in Dollars or in any other currency, against any principal of or
interest on any of such Lender's Loans, or any other amount payable to such
Lender hereunder, which is not paid when due (regardless of whether such
balances are then due to the Borrower), in which case it shall promptly notify
the Borrower and the Agent thereof, provided that such Lender's failure to give
such notice shall not affect the validity thereof.

                 (b)    If any Lender shall obtain payment of any principal of
or interest on any Loan made by it to the Borrower under this Agreement through
the exercise of any right of set-off, banker's lien or counterclaim or similar
right or otherwise, and, as a result of such payment, such Lender shall have
received a greater percentage of the principal or interest (or reimbursement)
then due hereunder by the Borrower to such Lender than the percentage received
by any other Lenders, it shall promptly (i) notify the Agent and each other
Lender thereof and (ii) purchase from such other Lenders participations in (or,
if and to the extent specified by such Lender, direct interests in) the Loans
made by such other Lenders (or in interest due thereon, as the case may be) in
such amounts, and make such other adjustments from time to time as shall be
equitable, to the end that all the Lenders shall share the benefit of such
excess payment (net of any expenses which may be incurred by such Lender in
obtaining or preserving such excess payment) pro rata in accordance with the
unpaid principal and/or interest on the Loans held by each of the Lenders. To
such end all the Lenders shall make appropriate adjustments among themselves (by
the resale of participations sold or otherwise) if such payment is rescinded or
must otherwise be restored. The Borrower agrees that any Lender so purchasing a
participation (or direct interest) in the Loans made by other Lenders (or in
interest due thereon, as the case may be) may exercise all rights of set-off,
banker's lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender were a direct holder of Loans in the

                                       20

<PAGE>

amount of such participation. Nothing contained herein shall require any Lender
to exercise any such right or shall affect the right of any Lender to exercise,
and retain the benefits of exercising, any such right with respect to any other
indebtedness or obligation of the Borrower. If under any applicable bankruptcy,
insolvency or other similar law, any Lender receives a secured claim in lieu of
a set-off to which this Section 4.05 applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Lenders entitled under this Section 4.05 to
share the benefits of any recovery on such secured claim.

         Section 4.06   Taxes.

                 (a)    Payments Free and Clear. Any and all payments by the
Borrower hereunder shall be made, in accordance with Section 4.01, free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender, and the Agent, taxes imposed on
its income, and franchise or similar taxes imposed on it, by (i) any
jurisdiction (or political subdivision thereof) of which the Agent, or such
Lender, as the case may be, is a citizen or resident or in which such Lender has
an Applicable Lending Office, (ii) the jurisdiction (or any political
subdivision thereof) in which the Agent, or such Lender is organized, or (iii)
any jurisdiction (or political subdivision thereof) in which such Lender, or the
Agent is presently doing business which taxes are imposed solely as a result of
doing business in such jurisdiction (all such non-excluded taxes, levies,
imposts, deductions, charges, withholdings and liabilities being hereinafter
referred to as "Taxes"). If the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder to the Lenders, or the
Agent (i) the sum payable shall be increased by the amount necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 4.06) such Lender, or the Agent (as
the case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant taxing
authority or other Governmental Authority in accordance with applicable law and
provide the relevant Lender with a receipt thereof.

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

                 (c)    Indemnification. To The Fullest Extent Permitted By
Applicable Law, The Borrower Will INDEMNIFY Each Lender And The Agent For The
Full Amount Of Taxes And Other Taxes (Including, But Not Limited To, Any Taxes
or Other Taxes Imposed by any Governmental Authority on amounts payable under
This Section 4.06) paid by such Lender or the Agent (on their behalf or on
behalf of any Lender), as the case may be, and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted
unless the payment of such Taxes was not correctly or legally asserted and such
Lender's

                                       21

Payment of such Taxes or Other Taxes was the result of its gross negligence or
wilfull misconduct. Any Payment pursuant to such indemnification shall be made
within thirty (30) Days after the date any Lender or the Agent, as the case may
be, makes written demand therefor. If any lender or the Agent receives a refund
or credit in respect of any taxes or Other Taxes for which such Lender or the
Agent has received payment form the Borrower it shall promptly notify the
Borrower of such refund or credit and shall, if no default has occurred and is
continuing, within thirty (30) days after receipt of a request by the Borrower
(or promptly upon receipt, if the Borrower has requested application for such
refung or credit pursuant hereto), pay an amount equal to such refund or credit
to the Borrower without interest (but with any interest so refunded or
credited), provided that the Borrower, upon the request of such Lender or the
Agent, agrees to return such refund or credit (plus penalties, interest or other
charges) to such lender or the Agent in the event such Lender or the Agent is
required to repay such refund or credit.

                 (d)    Lender Representations.

                        (i)    EachLender represents that it is either (1) a
         banking association or corporation organized under the laws of the
         United States of America or any state thereof or (2) entitled to
         complete exemption from United States withholding tax imposed on or
         with respect to any payments, including fees, to be made to it pursuant
         to this Agreement (A) under an applicable provision of a tax convention
         to which the United States of America is a party or (B) because it is
         acting through a branch, agency or office in the United States of
         America and any payment to be received by it hereunder is effectively
         connected with a trade or business in the United States of America.
         Each Lender that is not a banking association or corporation organized
         under the laws of the United States of America or any state thereof
         agrees to provide to the Borrower and the Agent on the Closing Date, or
         on the date of its delivery of the Assignment pursuant to which it
         becomes a Lender, and at such other times as required by United States
         law or as the Borrower or the Agent shall reasonably request, two
         accurate and complete original signed copies of U.S. Internal Revenue
         Service Form W-8ECI or W-8BEN or, in the case of a Lender claiming
         exemption from U.S. federal withholding tax under Section 871(h) or
         881(c) of the Code, a form W-8BEN, or other equivalent successor form,
         as appropriate, certifying in each case that such Lender is entitled to
         receive payments under this Agreement and the Note payable to it,
         without deduction or withholding of any U.S. federal income taxes and
         (ii) any other governmental forms which are necessary or required under
         an applicable tax treaty or otherwise by law to reduce or eliminate any
         withholding tax, which have been reasonably requested by the Borrower
         and the Agent. In addition, each Lender agrees that if it previously
         filed a Form W-8ECI or W-8BEN, it will deliver to the Borrower and the
         Agent a new Form W-8ECI or W-8BEN, as applicable, prior to the first
         payment date occurring in each of its subsequent taxable years. Each
         Lender which delivers to the Borrower and the Agent a Form W-8ECI or
         W-8BEN, or other equivalent successor form, as appropriate, further
         undertakes to deliver to the Borrower and the Agent two further copies
         of such form, or successor applicable forms, or other manner of
         certification, as the case may be, on or before the date that any such
         form expires or becomes obsolete or after the occurrence of any event
         requiring a

                                       22

<PAGE>

         change in the most recent form previously delivered by it to the
         Borrower and the Agent, and such extensions or renewals thereof as may
         reasonably be requested by the Borrower and the Agent certifying in the
         case of a Form W-8ECI or W-8BEN that such Lender is entitled to receive
         payments under this Agreement without deduction or withholding of any
         U.S. federal income taxes. If a Lender determines, as a result of any
         change in either (i) a Governmental Requirement or (ii) its
         circumstances, that it is unable to submit any form or certificate that
         it is obligated to submit pursuant to this Section 4.06, or that it is
         required to withdraw or cancel any such form or certificate previously
         submitted, it shall promptly notify the Borrower and the Agent of such
         fact. If a Lender is organized under the laws of a jurisdiction outside
         the United States of America, unless the Borrower and the Agent have
         received a Form W-8ECI or W-8BEN satisfactory to them indicating that
         all payments to be made to such Lender hereunder are not subject to
         United States withholding tax, the Borrower shall withhold taxes from
         such payments at the applicable statutory rate. Each Lender agrees to
         indemnify and hold harmless the Borrower or Agent, as applicable, from
         any United States taxes, penalties, interest and other expenses, costs
         and losses incurred or payable by (i) the Agent as a result of such
         Lender's failure to submit any form or certificate that it is required
         to provide pursuant to this Section 4.06 or (ii) the Borrower or the
         Agent as a result of their reliance on any such form or certificate
         which such Lender has provided to them pursuant to this Section 4.06.

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

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

                                    ARTICLE V
                                Capital Adequacy

         Section 5.01 Capital Adequacy; Additional Costs.

                (a) Capital Adequacy. The Borrower shall pay directly to any
Lender pursuant to the procedure set forth in Section 5.01(b) such amounts as
such Lender may

                                       23

<PAGE>

reasonably determine to be necessary to compensate such Lender or its parent or
holding company for any costs which it determines are attributable to the
maintenance by such Lender or its parent or holding company (or any Applicable
Lending Office), pursuant to any Governmental Requirement following any
Regulatory Change, of capital in respect of its Note or its Loan, such
compensation to include, without limitation, an amount equal to any reduction of
the rate of return on assets or equity of such Lender or its parent or holding
company (or any Applicable Lending Office) to a level below that which such
Lender or its parent or holding company (or any Applicable Lending Office) could
have achieved but for such Governmental Requirement. Such Lender will notify the
Borrower that it is entitled to compensation pursuant to this Section 5.01(a) as
promptly as practicable after it determines to request such compensation.

         (b)      Compensation Procedure. Any Lender notifying the Borrower of
the incurrence of additional costs under this Section 5.01 shall in such notice
to the Borrower and the Agent set forth in reasonable detail the basis and
amount of its request for compensation. Determinations and allocations by each
Lender for purposes of this Section 5.01 of the effect of any Regulatory Changes
or of the effect of capital maintained, on its costs or rate of return of
maintaining its Loan or on amounts receivable by it in respect of its Loan, and
of the amounts required to compensate such Lender under this Section 5.01, shall
be conclusive and binding for all purposes, provided that such determinations
and allocations are made on a reasonable basis. Any request for additional
compensation under this Section 5.01 shall be paid by the Borrower within thirty
(30) days of the receipt by the Borrower of the notice described in this Section
5.01(b).

                                   ARTICLE VI
                              Conditions Precedent

conditions precedent.

                                  ARTICLE VII
                         Representations and Warranties

         The Borrower represents and warrants to the Agent and the Lenders as
follows:

         Section 7.01 Corporate Existence. Each of the Borrower and each
Subsidiary: (i) is a corporation or limited liability company duly organized,
legally existing and in good standing under the laws of the jurisdiction of its
organization; (ii) has all requisite corporate or limited liability company
power, and 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 and where failure so to qualify would have a Material
Adverse Effect.

         Section 7.02 Financial Condition. The audited consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as at December 31, 2001
and the related consolidated statement of income, stockholders' equity and cash
flow of the Borrower and its Consolidated Subsidiaries for the fiscal year ended
on said date, with the opinion thereon of Price Waterhouse Coopers, L.L.P.
heretofore furnished to the Agent and the unaudited consolidated balance sheet
of the Borrower and its Consolidated Subsidiaries as at May 31, 2002 and their
related consolidated statements of income and cash flow of the Borrower and its
Consolidated Subsidiaries for the 5 month period ended on such date heretofore
furnished to the Agent, are complete and correct and fairly present the
consolidated financial condition of the Borrower and its Consolidated
Subsidiaries as at said dates and the results of its operations for the fiscal
year and the 5 month period on said dates, all in accordance with GAAP, as
applied on a consistent basis (subject, in the case of the interim financial
statements, to normal year-end adjustments). Neither the Borrower nor any
Subsidiary has on the Closing Date any material Debt, contingent liabilities,
liabilities for taxes, unusual forward or long-term commitments 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
May 31, 2002, there has been no change or event having a Material Adverse
Effect. Since the latest date of the Financial Statements, neither the business
nor the Properties of the Borrower or any Subsidiary have been materially and
adversely affected as a result of any fire, explosion, earthquake, flood,
drought, windstorm, accident, strike or other labor disturbance, embargo,
requisition or taking of Property or cancellation of contracts, permits or
concessions by any Governmental Authority, riot, activities of armed forces or
acts of God or of any public enemy.

                                       28

<PAGE>

         Section 7.03 Litigation. 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 could reasonably be expected to have a Material Adverse
Effect or purport to affect or pertain to this Agreement or any other Loan
Document or any of the transactions contemplated hereby or thereby, except as
disclosed in Schedule 7.03.

         Section 7.04 No Breach. After giving effect to Section 2.02(b), no
Default or Event of Default exists or would result from the restructuring of the
Prior Debt as contemplated thereby. 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 by-laws of
the Borrower or any Subsidiary, or 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 material agreement or instrument, or result in the
creation or imposition of any Lien upon any of the revenues or assets of the
Borrower or any Subsidiary pursuant to the terms of any such material agreement
or instrument other than the Liens created by the Loan Documents.

         Section 7.05 Authority. The Borrower and each Subsidiary have all
necessary corporate or limited liability company power 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 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 to which it is a party or for the validity or enforceability
thereof, except for the recording and filing of the Security Instruments as
required by this Agreement.

         Section 7.07 Use of Loans. The Borrower is not engaged principally, or
as one of its important activities, in the business of extending credit for the
purpose, whether immediate, incidental or ultimate, of buying or carrying margin
stock (within the meaning of Regulation G, T, U or X of the Board of Governors

create in favor of the Agent for the benefit of the Lenders a legal, valid and
enforceable security interest in all right, title, and interest of the Borrower
and its Subsidiaries, as applicable, in the collateral described therein and to
the extent permitted or provided for by applicable law; and the Agent for the
benefit of the Lenders has a perfected first priority security interest or

and deliver to the Agent upon request all such other documents, agreements and
instruments to comply with or accomplish the covenants and agreements of the
Borrower or any Subsidiary, as the case may be, in the Security Instruments and
this Agreement, or to further evidence and more fully describe the collateral

Instruments, or to state more fully the security obligations set out herein or

           (b)    Certain Unperfected Interests. As of the Closing Date,
Borrower and Lenders recognize that Borrower and its Subsidiaries may not have
obtained complete legal title to certain of their assets or assets of their
respective Existing PC's consistent with the Management Services Agreements and
other contracts between Borrower and its Subsidiaries and their Existing PC's,
including, without limitation, those certain assets set forth on Schedule
8.05(b) (herein referred to as the "Unperfected Assets"). Borrower will and will
cause each Subsidiary to do all things reasonably necessary to perfect liens and
security interests in favor of Agent on behalf of the Lenders or otherwise
obtain legal title to all such Unperfected Assets within 30 days after the
Closing Date; provided if Borrower reasonably determines that undertaking such
actions will undermine or otherwise act to the detriment of the business
relationship between Borrower and its Subsidiaries and their respective Existing
PC's, Borrower will provide written notice to Agent setting forth a written
explanation thereof in lieu of such perfection or obtaining legal title prior to
the end of said 30-day period. If, after receipt of such written explanation,
Agent requests the Borrower to nevertheless pursue such perfection and/or obtain
legal title to the Unperfected Assets, Borrower shall or shall cause its
Subsidiaries to immediately commence such pursuit of such perfection or legal
control. Notwithstanding any provision herein to the contrary, Borrower shall
and shall cause its Subsidiaries to use best efforts to cause each of the
Existing PC's to grant Agent on behalf of Lenders a security interest in all of
their respective assets, including, without limitation, the Unperfected Assets
and any after-acquired property obtained by such Existing PC's.

     Section 8.06 Performance of Obligations. The Borrower will pay the Notes
according to the reading, tenor and effect thereof; and the Borrower will and
will cause each Subsidiary to do and perform every act and discharge all of the
obligations to be performed and discharged by them under the Security
Instruments and this Agreement, at the time or times and in the manner
specified. In furtherance of the foregoing, Borrower will, and will cause each
Subsidiary to, establish, maintain and comply at all times with the accounts
receivable collection procedures and cash management systems as set forth in the
Security Instruments and any agreements related thereto.

     Section 8.07 ERISA Information and Compliance. The Borrower will promptly
furnish and will cause the Subsidiaries and any ERISA Affiliate to promptly
furnish to the Agent with sufficient copies to the Lenders (i) promptly after
the filing thereof with the United States Secretary of Labor, the Internal
Revenue Service or the PBGC, copies of each annual and other report with respect
to each Plan or any trust created thereunder, (ii) immediately upon becoming
aware of the occurrence of any ERISA Event or of any "prohibited transaction,"
as described in section 406 of ERISA or in section 4975 of the Code, in
connection with any Plan or any trust created thereunder, a written notice
signed by a Responsible Officer specifying the nature thereof, what action the
Borrower, the Subsidiary or the ERISA Affiliate is taking or proposes to take
with respect thereto, and, when known, any action taken or proposed by the
Internal Revenue Service, the Department of Labor or the PBGC with respect
thereto, and (iii) immediately upon receipt thereof, copies of any notice of the
PBGC's intention to terminate or to have a trustee appointed to administer any
Plan. With respect to each Plan (other than a Multiemployer Plan), the Borrower
will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full
and in a timely manner, without incurring any late payment or underpayment
charge or penalty and without giving rise to any lien, all of the contribution
and funding requirements of section 412 of the Code (determined without regard
to subsections (d), (e), (f)

                                       39

<PAGE>

and (k) thereof) and of section 302 of ERISA (determined without regard to
sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the
PBGC in a timely manner, without incurring any late payment or underpayment
charge or penalty, all premiums required pursuant to sections 4006 and 4007 of
ERISA.

     Section 8.08 Management Services Agreements and Accounts Receivable
Purchase Agreements. The Borrower will and will cause each Subsidiary to do all
things necessary to maintain and keep in full force and effect and to enforce
compliance with the Management Services Agreements and the Accounts Receivable
Purchase Agreements. In the event that a new Subsidiary is formed, any
Management Services Agreements and Accounts Receivable Purchase Agreements
binding such Subsidiary shall be included within the terms of this affirmative
covenant.

     Section 8.09 Inspection of Property and Books and Records. The Borrower
shall maintain, and shall cause each of its Subsidiaries to maintain, proper
books of record and account, in which full, true and correct entries in
conformity with GAAP consistently applied shall be made of all financial
transactions and matters involving the assets and business of the Borrower and
such Subsidiary and consistent with Borrower's 10K and 10Q filings. The Borrower
shall permit, and shall cause each Subsidiary to permit, non-legal
representatives and independent consultants and contractors of the Agent and the
Lenders to visit and inspect any of their respective properties and Collateral,
to examine the Borrower's and each of its Subsidiaries' corporate, financial and
operating records, and to make copies thereof or abstracts therefrom, and to
discuss their respective affairs, finances and accounts with their respective
directors, officers, and independent public accountants, all at the reasonable
expense of the Borrower at such reasonable times during normal business hours
and as often as may be reasonably required for the reasonable administration of
this Agreement, upon three (3) Business Days' prior written notice to the
Borrower. The Lenders will have the specific right to conduct the first such on
site inspections of Borrower and its Subsidiaries within 60 days of the Closing
Date and annually thereafter within 12 months of the first such site
inspections.

     Section 8.10 Best Efforts to Prepay. Notwithstanding the Final Maturity
Date, Borrower will use best efforts, commencing on January 1, 2005, to prepay
the Loans in full.

     Section 8.11 Authorized Shares.

           (a)    Within 75 days after the Closing Date, the Borrower shall
amend its Certificate of Incorporation and, if necessary, its Bylaws, to (i)
increase the authorized shares of preferred stock or cause a reverse stock
split, in either case, so that 100% of the number of shares of Series A-2
Preferred Stock are authorized and reserved to provide for the exercise of the
rights represented by the Warrants, (ii) increase the authorized shares of
Common Stock or cause a reverse stock split, in either case, so that 100% of the
number of shares of Common Stock are authorized and reserved to provide for the
exercise of the rights then represented by the Preferred Stock and (iii) reduce
the par value of the Common Stock so that such par value is below the price
required by Section 153(a) of the Delaware General Corporation Law, or any
successor statute, to provide for the exercise of the Warrants and subsequent
conversion of the Series A-2 Preferred Stock. Without limiting the generality of
the foregoing sentence, as soon as practicable after the Closing Date, but in no
event later than 75 days after the Closing Date, the Borrower

                                       40

<PAGE>

shall hold a meeting of its stockholders for the authorization of either a
reverse stock split or an increase in the number of authorized shares of
Preferred Stock and Common Stock, and a decrease in the par value of the Common
Stock to meet the requirements of clause (iii) above.

             (b)  At all times subsequent to the 75/th/ day after the Closing
Date and during the period within which the rights represented by the Warrants
and the Series A-2 Preferred Stock may be exercised, (i) the Borrower will at
all times have authorized and reserved at least (A) 100% of the number of shares
of Series A-2 Preferred Stock needed to provide for the exercise of the rights
then represented by the Warrants and (B) 100% of the number of shares of Common
Stock needed to provide for the exercise of the rights then represented by the
Series A-2 Preferred Stock and (ii) the par value of said shares will at all
times be less than or equal to the price required by Section 153(a) of the
Delaware General Corporation Law, or any successor statute, to provide for the
exercise of the Warrants and subsequent conversion of the Series A-2 Preferred
Stock.

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

     Section 11.04 Rights as a Lender. With respect to any Loan made by it, Bank
of America (and any successor acting as Agent) in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as the Agent, and the
term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include the Agent in its individual capacity. Bank of America (and any successor
acting as Agent) and its Affiliates may (without having to account therefor to
any Lender) accept deposits from, lend money to and generally engage in any kind
of banking, trust or other business with the Borrower (and any of its
Affiliates) as if it were not acting as the Agent, and Bank of America and its
Affiliates may accept fees and other consideration from the Borrower for
services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

     Section 11.05 Indemnification. The Lenders agree to indemnify the Agent
ratably in accordance with their Percentage Shares for the Indemnity Matters as
described in

                                       53

<PAGE>

Section 12.03 to the extent not indemnified or reimbursed by the Borrower under
Section 12.03, but without limiting the obligations of the Borrower under said
Section 12.03 and for any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of: (i) this
Agreement, the Security Instruments or any other documents contemplated by or
referred to herein or the transactions contemplated hereby, but excluding,
unless a Default has occurred and is continuing, normal administrative costs and
expenses incident to the performance of its agency duties hereunder or (ii) the
enforcement of any of the terms of this Agreement, any Security Instrument or of
any such other documents; whether or not any of the foregoing specified in this
Section 11.05 arises from the sole or concurrent negligence of the Agent,
provided that no Lender shall be liable for any of the foregoing to the extent
they arise from the gross negligence or willful misconduct of the Agent.

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

     Section 11.07 Action by Agent. Except for action or other matters expressly
required of the Agent hereunder, the Agent shall in all cases be fully justified
in failing or refusing to act hereunder unless it shall (i) receive written
instructions from the Majority Lenders (or all of the Lenders as expressly
required by Section 12.04) specifying the action to be taken, and (ii) be
indemnified to its satisfaction by the Lenders against any and all liability and
expenses which may be incurred by it by reason of taking or continuing to take
any such action. The instructions of the Majority Lenders (or all of the Lenders
as expressly required by Section 12.04) and any action taken or failure to act
pursuant thereto by the Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, the Agent shall take such action with
respect to such Default as shall be directed by the Majority Lenders (or all of
the Lenders as required by Section 12.04) in the written instructions (with
indemnities) described in this Section 11.07,

                                       54

<PAGE>

provided that, unless and until the Agent shall have received such directions,
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall deem advisable in
the best interests of the Lenders. In no event, however, shall the Agent be
required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement and the Security Instruments or applicable
law.

     Section 11.08 Resignation or Removal of Agent. Subject to the appointment
and acceptance of a successor Agent as provided below, the Agent may resign at
any time by giving notice thereof to the Lenders and the Borrower, and the Agent
may be removed at any time with or without cause by the Majority Lenders. Upon
any such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Agent. If no successor Agent shall have been so appointed by
the Majority Lenders and shall have accepted such appointment within thirty (30)
days after the retiring Agent's giving of notice of resignation or the Majority
Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf
of the Lenders, appoint a successor Agent. Upon the acceptance of such
appointment hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder. After any retiring Agent's resignation or
removal hereunder as Agent, the provisions of this Article XI and Section 12.03
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Agent.

                                  ARTICLE XII
                                  Miscellaneous

     Section 12.01 Waiver. No failure on the part of the 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. All notices and other communications provided for
herein and in the other Loan Documents (including, without limitation, any
modifications of, or waivers or consents under, this Agreement or the other Loan
Documents) shall be given or made by telex, telecopy, courier or U.S. Mail or in
writing and telexed, telecopied, mailed or delivered to the intended recipient
at the "Address for Notices" specified below its name on the signature pages
hereof or in the Loan Documents; to each other party. Except as otherwise

succeeding Business Day) by telex or telecopier and evidence or confirmation of
receipt is obtained, or personally delivered or, in the case of a mailed notice,
three (3) Business Days after the date deposited in the mails, postage prepaid,
in each case given or addressed as aforesaid.

         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 Prior Debt,
         (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 Security Instrument 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

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

              (iii) to indemnify and hold harmless from time to time the
         Indemnified Parties from and against any and all losses, claims, cost
         recovery actions, administrative orders or proceedings, damages and

         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

                                       56

<PAGE>

         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 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 the 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, the 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) 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 Notes and shall
continue thereafter in full force and effect.

12.03 within thirty (30) days of the receipt by the Borrower of notice of the

     Section 12.04 Amendments, Etc. Any provision of this Agreement or any
Security Instrument may be amended, modified or waived with the Borrower's and
the Majority Lenders' prior written consent; provided that (i) no amendment,
modification or waiver which extends the final maturity of the Loans, postpones
the scheduled payment date of any amount owing under any Loan Document,
increases the Aggregate Maximum Credit Amounts, forgives the principal amount of
any Indebtedness outstanding under this Agreement, releases any guarantor of the
Indebtedness or releases all or substantially all of the collateral, reduces the
interest rate applicable to the Loans or the fees payable to the Lenders
generally, affects Section 2.01, this Section 12.04 or Section 12.06(a) or
modifies the definition of "Majority Lenders" shall be effective without consent
of all Lenders; (ii) no amendment, modification or waiver which increases the
Maximum Credit Amount of any Lender shall be effective without the consent of
such Lender; (iii) no amendment, modification or waiver which modifies the
rights, duties or obligations of the Agent shall be effective without the
consent of the Agent, and (iv) no amendment, modification or waiver of the
Subordination Agreement shall be effective without the consent of all Lenders.

     Section 12.05 Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns, and no third party shall be deemed a third party
beneficiary hereof.

     Section 12.06 Assignments and Participations.

              (a) The Borrower may not assign its rights or obligations
hereunder or under the Notes without the prior consent of all of the Lenders and
the Agent.

              (b) Any Lender may assign only to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement; provided,
however, that (i) any such assignment shall be in the amount of at least
$1,000,000 or such lesser amount to which the Majority Lenders have consented
and (ii) the assignee or assignor shall pay to the Agent a processing and
recordation fee of $3,000 for each assignment. As used herein, the term
"Eligible Assignee" shall mean (a) a Lender or Affiliate thereof, (b) a
commercial bank, or other finance, insurance or other financial entity or fund
which, with its Affiliates, has total assets (including assets under management
or pledge) of not less than $50,000,000, or (c) such other Person to which the
Majority Lenders have consented and, if no Event of Default has occurred and is
continuing, the Borrower has consented, such consents not to be unreasonably
withheld or delayed. Any such assignment will become effective upon the
execution and delivery to the Agent of the Assignment and the consent of the
Agent and the Borrower, if applicable. Promptly after receipt of an executed
Assignment, the Agent shall send to the Borrower a copy of such executed
Assignment. Upon receipt of such executed Assignment, the Borrower, will, at its
own expense, execute and deliver new Notes to the assignor and/or assignee, as
appropriate, in accordance with their respective interests as they appear. Upon
the effectiveness of any assignment pursuant to this Section 12.06(b), the
assignee will become a "Lender," if not already a "Lender," for all purposes of
this Agreement and the Security Instruments. The assignor shall be relieved of
its obligations hereunder to the extent of such assignment (and if the assigning
Lender no longer holds any rights or obligations under this Agreement, such
assigning Lender shall cease to be a "Lender" hereunder except that its rights
under Sections 4.06, 5.01 and 12.03 shall not be affected). The Agent will
prepare on the last Business Day of each month during

                                       58

<PAGE>

which an assignment has become effective pursuant to this Section 12.06(b), a
new Annex I giving effect to all such assignments effected during such month,
and will promptly provide the same to the Borrower and each of the Lenders.

              (c) Each Lender may transfer, grant or assign participations in
all or any part of such Lender's interests hereunder pursuant to this Section
12.06(c) to any Person, provided that: (i) such Lender shall remain a "Lender"
for all purposes of this Agreement and the transferee of such participation
shall not constitute a "Lender" hereunder; and (ii) no participant under any
such participation shall have rights to approve any amendment to or waiver of
any of the Loan Documents except to the extent such amendment or waiver would
(x) forgive any principal owing on any Indebtedness or extend the final maturity
of the Loans, (y) reduce the interest rate (other than as a result of waiving
the applicability of any post-default increases in interest rates) or fees
applicable to any of the Loans in which such participant is participating, or
postpone the payment of any thereof, or (z) release any guarantor of the
Indebtedness or release all or substantially all of the collateral (except as
provided in the Loan Documents) supporting any of the Loans in which such
participant is participating. In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the
Security Instruments (the participant's rights against the granting Lender in
respect of such participation to be those set forth in the agreement with such
Lender creating such participation), and all amounts payable by the Borrower
hereunder shall be determined as if such Lender had not sold such participation,
provided that such participant shall be entitled to receive additional amounts
under Article V on the same basis as if it were a Lender and be indemnified
under Section 12.03 as if it were a Lender. In addition, each agreement creating
any participation must include an agreement by the participant to be bound by
the provisions of Section 12.15.

              (d) The Lenders may furnish any information concerning the
Borrower in the possession of the Lenders from time to time to assignees and
participants (including prospective assignees and participants); provided that,
such Persons agree to be bound by the provisions of Section 12.15.

              (e) Notwithstanding anything in this Section 12.06 to the
contrary, any Lender may assign and pledge its Notes to any Federal Reserve
Bank. No such assignment and/or pledge shall release the assigning and/or
pledging Lender from its obligations hereunder.

    Section 12.07 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 the Notes, this
Agreement or any Security Instrument.

    Section 12.08 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart.

    Section 12.09 References. The words "herein," "hereof," "hereunder" and
other words of similar import when used in this Agreement refer to this
Agreement as a whole, and not to any particular article, section or subsection.
Any reference herein to a Section shall be deemed to refer to the applicable

exhibit or schedule attached hereto unless otherwise stated herein.

     Section 12.10 Survival. The obligations of the parties under Section 4.06,
Article V, and Sections 11.05 and 12.03 shall survive the repayment of the Loans
and the termination of the Commitments. To the extent that any payments on the
Indebtedness 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 Indebtedness so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Agent's and the Lenders' Liens, security interests,
rights, powers and remedies under this Agreement and each Security Instrument
shall continue in full force and effect. In such event, each Security Instrument
shall be automatically reinstated and the Borrower shall take such action as may
be reasonably requested by the Agent and the Lenders to effect such
reinstatement.

     Section 12.11 Captions. Captions and section headings appearing herein are
included solely for convenience of reference and are not intended to affect the
interpretation of any provision of this Agreement.

     Section 12.12 No Oral Agreements. The Loan Documents embody the entire
agreement and understanding between the parties and supersede all other
agreements and understandings between such parties relating to the subject
matter hereof and thereof. The Loan Documents represent the final agreement
between the parties and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
unwritten oral agreements between the parties.

     Section 12.13 Governing Law; Submission to Jurisdiction; Waiver of Jury
Trial.

             (a)   This Agreement and the Notes shall be governed by, and
construed in accordance with, the laws of the State of Texas except to the
extent that United States federal law permits any Lender to charge interest at
the rate allowed by the laws of the state where such Lender is located. Chapter
346 of the Texas Finance Code (which regulates certain revolving credit loan
accounts and revolving tri-party accounts) shall not apply to this Agreement or
the Notes.

             (b)   Subject to Section 12.17, any legal action or proceeding with
respect to the Loan Documents shall be brought in the courts of the State of
Texas or of the United States of America for the Southern District of Texas,
and, by execution and delivery of this Agreement, each of the Borrower, the
Agent and the Lenders hereby accepts for itself and (to the extent permitted by
law) in respect of its Property, generally and unconditionally, the jurisdiction
of the aforesaid courts. Each of the Borrower, the Agent and the Lenders hereby
irrevocably waives any objection, including, without limitation, any objection
to the laying of venue or based on the grounds of forum non conveniens, which it
may now or hereafter have to the bringing of any such action or proceeding in
such respective jurisdictions.

                                       60

<PAGE>

              (c)  Nothing herein shall affect the right of the Agent or any
Lender or any holder of a Note to serve process in any other manner permitted by
law.

              (d)  The Borrower, the Agent and each Lender hereby (i)
irrevocably and unconditionally waive, to the fullest extent permitted by law,
trial by jury in any legal action or proceeding relating to this Agreement, any
Security Instrument or any other Loan Document and with respect to any
counterclaim asserted therein; (ii) irrevocably waive, to the maximum extent not
prohibited by law, any right it may have to claim or recover in any such
litigation or other legal proceeding any special, exemplary, punitive or
consequential damages, or damages other than, or in addition to, actual damages;
(iii) certify that no party hereto nor any representative or agent of counsel
for any party hereto has represented, expressly or otherwise, or implied that
such party would not, in the event of litigation, seek to enforce the foregoing
waivers, and (iv) acknowledge that it has been induced to enter into this
Agreement, the Security Instruments and the transactions contemplated hereby and
thereby by, among other things, the mutual waivers and certifications contained
in this Section 12.13.

     Section 12.14 Interest. It is the intention of the parties hereto that each
Lender shall conform strictly to usury laws applicable to it. Accordingly, if
the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the Highest Lawful Rate, and any excess
shall be canceled automatically and if theretofore paid shall be credited by
such Lender on the principal amount of the Indebtedness (or, to the extent that
the principal amount of the Indebtedness shall have been or would thereby be
paid in full, refunded by such Lender to the Borrower); and (ii) in the event
that the maturity of the Notes is accelerated by reason of an election of the
holder thereof resulting from any Event of Default under this Agreement or
otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Agreement or otherwise shall be
canceled automatically by such Lender as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Borrower). All sums paid or agreed to be paid to
any Lender for the use, forbearance or detention of sums due hereunder shall, to
the extent permitted by law applicable to such Lender, be amortized, prorated,
allocated and spread throughout the full term of the Loans evidenced by the
Notes until payment in full so that the rate or amount of interest on account of
any Loans hereunder does not exceed the maximum amount allowed by such
applicable law. If at any time and from time to time (i) the amount of interest
payable to any Lender on any date shall be computed at the Highest Lawful Rate
applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of
any subsequent interest

                                       61

computation period the amount of interest otherwise payable to such Lender would
be less than the amount of interest payable to such Lender computed at the
Highest Lawful Rate applicable to such Lender, then the amount of interest
payable to such Lender in respect of such subsequent interest computation period
shall continue to be computed at the Highest Lawful Rate applicable to such
Lender until the total amount of interest payable to such Lender shall equal the
total amount of interest which would have been payable to such Lender if the
total amount of interest had been computed without giving effect to this Section
12.14. To the extent that Chapter 303 of the Texas Finance Code is relevant for
the purpose of determining the Highest Lawful Rate, such Lender elects to
determine the applicable rate ceiling under such Chapter by the indicated weekly
rate ceiling from time to time in effect.

     Section 12.15 Confidentiality. In the event that the Borrower provides to
the Agent or the Lenders written confidential information belonging to the
Borrower, if the Borrower shall denominate such information in writing as
"confidential", the Agent and the Lenders shall thereafter maintain such
information in confidence in accordance with the standards of care and diligence
that each utilizes in maintaining its own confidential information. This
obligation of confidence shall not apply to such portions of the information
which (i) are in the public domain, (ii) hereafter (but not until they) become
part of the public domain without the Agent or the Lenders breaching their
obligation of confidence to the Borrower, (iii) are previously known by the
Agent or the Lenders from some source other than the Borrower, (iv) are
hereafter developed by the Agent or the Lenders without using the Borrower's
information, (v) are hereafter obtained by or available to the Agent or the
Lenders from a third party who owes no obligation of confidence to the Borrower
with respect to such information or through any other means other than through
disclosure by the Borrower, (vi) are disclosed with the Borrower's consent,
(vii) must be disclosed either pursuant to any Governmental Requirement or to
Persons regulating the activities of the Agent or the Lenders, (viii) as may be
required by law or regulation or order of any Governmental Authority in any
judicial, arbitration or governmental proceeding, or (ix) are disclosed in
connection with the enforcement or exercise of the Agent's or any Lender's
rights and remedies under any Loan Document and not otherwise prohibited by law.
Further, the Agent or a Lender may disclose any such information to any other
Lender, any independent consultants, any independent certified public
accountants, any legal counsel employed by such Person in connection with this
Agreement, any Security Instrument or any other Loan Document, including without
limitation, the enforcement or exercise of all rights and remedies thereunder,
or any assignee or participant (including prospective assignees and
participants) in the Loans; provided, however, that the Agent or the Lenders
shall receive a confidentiality agreement from the Person (excluding legal
counsel) to whom such information is disclosed such that said Person shall have
the same obligation to maintain the confidentiality of such information as is
imposed upon the Agent or the Lenders hereunder. Notwithstanding anything to the
contrary provided herein, this obligation of confidence shall cease three (3)
years from the date the information was furnished, unless the Borrower requests
in writing at least thirty (30) days prior to the expiration of such three year
period, to maintain the confidentiality of such information for an additional
three year period. The Borrower waives any and all other rights it may have to
confidentiality as against the Agent and the Lenders arising by contract,
agreement, statute or law except as expressly stated in this Section 12.15.

     Section 12.16 Effectiveness. This Agreement shall be effective on the
Closing Date.

     Section 12.17 Binding Arbitration.

         (a) Any controversy or claim between or among the parties hereto,
including but not limited to, those arising out of or relating to this
Agreement, the Notes, the Security Instruments or any other Loan Document,
including any claim or controversy of any kind based on or arising in tort,
shall be determined by binding arbitration in accordance with the Federal
Arbitration Act (or if not applicable, applicable state law), the Rules of
Practice and Procedure for the Arbitration of Commercial Disputes or Judicial
Arbitration and Mediation Services, Inc. ("J.A.M.S."), and the rules set forth
in Section 12.17(b) below. In the event of any inconsistency, the rules set
forth in Section 12.17(b) below shall control. Judgment upon any arbitration
award may be entered in any court having jurisdiction. Any party to the Notes or
any other Security Instrument may bring an action, including a summary or
expedited proceeding, to compel arbitration or any controversy or claim to which
either the Notes, this Agreement or any other Security Instrument applies in any
court having jurisdiction over such action.

         (b) The arbitration shall be conducted in the City of Houston, Texas
and administered by J.A.M.S. who will appoint an arbitrator. If J.A.M.S. is
unable or legally precluded from administering the arbitration, then the
American Arbitration Association will serve. All arbitration hearings will be
commenced within 90 days of the demand for arbitration, and the arbitrator
shall, only upon a showing of cause, be permitted to extend the commencement of
such hearings for an additional 60 days.

         (c) Nothing in this Agreement shall be deemed to (i) limit the
applicability of any otherwise applicable statutes of limitation or repose or
any waivers contained in this Agreement, the Notes, the Guaranty Agreement or
the other Security Instruments; (ii) be a waiver by any Lender of the protection
afforded to it by 12 U.S.C. ss.91 or any substantially equivalent state law; or
(iii) limit the right of any Lender to (a) exercise self help remedies such as,
but not limited to, setoff, (b) foreclose against any collateral, whether real
or personal property, or (c) obtain from a court provisional or ancillary
remedies such as, but not limited, injunctive relief, writ of possession or the
appointment of a receiver. Any Lender may exercise such self help rights,
foreclose upon collateral, or obtain such provisional or ancillary remedies
before, during or after the pendency of any arbitration proceeding brought
pursuant to the Notes, this Agreement or the other Security Instruments. Neither
the exercise of self help remedies nor the institution or maintenance of an
action for foreclosure or provisional or ancillary remedies shall constitute a
waiver of the right of any party, including the claimant in such action, to
arbitrate the merits of the controversy or claim occasioning the resort to such
remedies.

         (d) The provisions of this Section 12.17 shall survive any termination,
amendment, or expiration of the Security Instruments. Each party agrees to keep
all disputes and arbitration proceedings strictly confidential, except for
disclosures of information required in the ordinary course of its business or by
applicable law or regulation.

         (e) Nothing in this Agreement shall be deemed to limit the right of the
Borrower to obtain injunctive relief against any Lender prior to or during the
pendency of

                                       63

<PAGE>

any arbitration proceeding based on violations by any Lender of any Lender's
agreements with the Borrower, so long as the injunctive relief is limited to
restraining any Lender from exercising its rights and remedies until the
arbitration proceeding (in process or initiated by the Borrower or any Lender in
conjunction with the request for such injunctive relief) has been completed and
arbitration award has been made.

     Section 12.18 Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement, the Security
Instruments and the other Loan Documents and agrees that it is charged with
notice and knowledge of all of their terms; 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, the Security Instruments and the other Loan
Documents; and has received the advice of its attorney in entering into this
Agreement, the Security Instruments and the other Loan Documents; and that it
recognizes that certain of the terms of this Agreement and the Security
Instruments result in one party assuming the liability inherent in some aspects
of the transaction and relieving the other party of its responsibility for such
liability. Each party hereto agrees and covenants that it will not contest the
validity or enforceability of any exculpatory provision of this Agreement, the
Security Instruments 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 12.19 Reaffirmation of Guaranty Agreement and Security Agreement.
Each Guarantor hereby consents to this Agreement and agrees that the execution
and the performance of such Agreement shall not in any way affect, impair,
discharge, relieve or release such Guarantor from its obligations under its
respective Guaranty Agreement or under any Security Instrument executed by it.
Each Guarantor reaffirms its respective Guaranty Agreement and any Security
Instruments executed by it and agrees that: (i) such Guaranty Agreement and
Security Instruments are in full force and effect to guarantee payment and
performance of the "Liabilities" as defined therein; and (ii) its respective
obligations under such agreements shall continue to be in full force and effect
until its respective obligations thereunder or hereunder are fully paid and
performed. In furtherance of the foregoing, each Guarantor affirms that each
reference in its respective Guaranty Agreement to the "Credit Agreement", the
"Loan Documents", the "Notes" and the "Security Instruments" are, respectively,
references to this Agreement, Loan Documents, the Notes and Security Instruments
as defined in this Agreement, together with all renewals, restatements,
rearrangements, amendments, extensions, or supplements in whole or in part of
any of the foregoing. In addition to the foregoing, each Guarantor affirms,
acknowledges and agrees that (a) the "Liabilities" as defined and described in
its respective Guaranty Agreement shall be deemed to cover and include not only
those items set forth in the definition of Liabilities in its respective
Guaranty Agreement, but also the Indebtedness and Loans as defined and described
in this Agreement, together with all renewals, restatements, rearrangements,
increases, extensions for any period, amendments or supplements in whole or in
part of such Indebtedness or Loans; (b) each of the Lenders named in this
Agreement, together with their respective successors and assigns, and the Agent
shall be entitled to the benefits of such Guarantor's respective Guaranty
Agreement and all obligations of such Guarantor thereunder; and (c) Bank of
America, N.A., f/k/a NationsBank, N.A., is the successor in interest by reason
of merger to NationsBank of Texas, N.A.

     up of a Person.

     Reorganization Subordinated Securities shall mean (a) any equity securities
     issued in substitution of all or any portion of the Junior Debt that are
     subordinated in right of payment to the Senior Debt (or any notes or other
     securities issued in substitution of all or any portion of the Senior
     Debt), and (b) any notes or other debt securities issued in substitution of
     all or any portion of the Junior Debt that are subordinated to the Senior
     Debt (or any notes or other securities issued in substitution of all or any
     portion of the Senior Debt) to the same extent that the Junior Debt is
     subordinated to the Senior Debt pursuant to the terms of this Agreement.

     Senior Creditor shall mean the Agent and any party to the Credit Agreement
     as a Lender.

     Senior Debt shall mean: (a) all principal, interest, fees, reimbursements,
     indemnifications and other amounts now or hereafter owed by the Company to
     Senior Creditors under the Credit Agreement and other Loan Documents and
     (b) any increases, extensions and rearrangements of the foregoing
     obligations under any amendments, supplements and other modifications of
     the documents and agreements creating the foregoing obligations to the
     extent permitted under Section 3 hereof; provided, however, that in no
     event shall the principal amount of the Senior Debt exceed the sum of the
     aggregate principal amount of Senior Debt outstanding on the date hereof
     plus $2,000,000, reduced by the amount of any repayments and prepayments
     thereof (it being understood that no amounts expended by any Senior
     Creditor to preserve the value of, or otherwise protect, the Collateral,
     shall be subject to, or included within, the foregoing limitations).

     Subsidiaries shall mean, collectively, Academy, Castle West, Castle

     Subsidiary.

     2. Subordination.

          2.1 Subordination of Junior Debt to Senior Debt. The Company and each
     Subsidiary covenants and agrees, and each Junior Creditor by its acceptance
     of a Junior Note (whether upon original issue or upon transfer or
     assignment) likewise covenants and agrees, that unless and until the Senior
     Debt shall have been irrevocably paid in full, the payment and performance
     of the Junior Debt is hereby made expressly subordinate and junior in right
     of payment and performance to the prior payment and performance of all
     obligations and liabilities under the Senior Debt to the extent and in the
     manner set forth in this Section 2. Each holder of Senior Debt, whether now
     outstanding or hereafter created, incurred, assumed or guaranteed, and
     whether such holder holds any Senior Debt as of the date hereof or later
     becomes a holder by means of assignment or otherwise, shall be deemed to
     have acquired Senior Debt in reliance upon the provisions contained in this
     Agreement.

                                      D-3

<PAGE>

          2.2 Proceedings. In the event of any Proceeding involving the Company,
     (a) all Senior Debt first shall be paid in full before any payment of or
     with respect to the Junior Debt shall be made (other than a distribution of
     Reorganization Subordinated Securities); and (b) any payment or
     distribution, whether in cash, property or securities which, but for the
     terms hereof, otherwise would be payable or deliverable in respect of the
     Junior Debt (other than a distribution of Reorganization Subordinated
     Securities), shall be paid or delivered directly to Agent (to be held
     and/or applied by Agent in accordance with the terms of the Credit
     Agreement) until all Senior Debt is irrevocably paid in full, and each
     Junior Creditor irrevocably authorizes, empowers and directs all receivers,
     trustees, liquidators, custodians, conservators and others having authority
     in the premises to effect all such payments and distributions.

          In the event of any Proceeding involving any Subsidiary, (a) all
     payments or distributions in such Proceeding shall be applied to Senior
     Debt before any payment of or with respect to the Junior Debt shall be made
     (other than a distribution of Reorganization Subordinated Securities); and
     (b) any payment or distribution, whether in cash, property or securities
     which, but for the terms hereof, otherwise would be payable or deliverable
     in respect of the Junior Debt (other than a distribution of Reorganization
     Subordinated Securities) in such Proceeding, shall be paid or delivered
     directly to Agent (to be held and/or applied by Agent in accordance with
     the terms of the Credit Agreement) until all Senior Debt is irrevocably
     paid in full, and each Junior Creditor irrevocably authorizes, empowers and
     directs all receivers, trustees, liquidators, custodians, conservators and
     others having authority in the premises to effect all such payments and
     distributions.

          2.3 Limitation on Payments.

          (a) Neither the Company nor any Subsidiary may make, and no Junior
     Creditor may receive, any payment or prepayment of any sum with respect to
     the Junior Debt (other than reimbursement of actual and reasonable
     out-of-pocket costs and expenses not to exceed, with respect to periods
     prior to the Closing Date, $50,000) until all of the Senior Debt shall have
     been irrevocably paid in full.

          (b) The provisions of this subsection 2.3 shall not apply to any
     payment with respect to which subsection 2.2 would be applicable.

          2.4 Subordination of Liens and Guarantees. The Junior Creditors will
     not create, assume, or suffer to exist any lien, security interest,
     guaranty, or assignment of collateral securing or guaranteeing the
     repayment of the Junior Debt. Any judgment lien, and any other lien,
     security interest, guaranty or assignment existing in violation of the
     foregoing shall be fully subordinate to any lien, security interest,
     guaranty or assignment in favor of the Senior Creditors which secures any
     of the Senior Debt, and the Junior Creditors, the Company and the
     Subsidiaries shall immediately take any and all steps necessary to effect
     the release of any such lien, security interest, assignment or collateral
     or the termination of any such guaranty.

          2.5 Restriction on Action by the Junior Creditors.

                                      D-4

<PAGE>

          (a) Until the Senior Debt is paid in full, no Junior Creditor shall,
     without the prior written consent of the Senior Lenders, take any
     Enforcement Action with respect to the Junior Debt, except as permitted in
     the following sentence. Upon the earlier to occur of:

               (i) acceleration of the Senior Debt; or

               (ii) commencement of a Proceeding with respect to the Company;

     the Junior Creditors may accelerate the Junior Debt or take any other
     Enforcement Action; provided, however, that if following the acceleration
     of the Senior Debt, such acceleration is rescinded, then all Enforcement
     Actions taken by the Junior Creditors shall likewise be rescinded if such
     Enforcement Action is based solely on such acceleration.

          (b) Until the Senior Debt is irrevocably paid in full and
     notwithstanding anything contained in the Junior Debt Documents, the Credit
     Agreement or any of the other Loan Documents to the contrary, no Junior
     Creditor shall, without the prior written consent of Agent (which consent
     may be withheld in the Agent's sole discretion), agree to any amendment,
     modification or supplement to the Junior Debt Documents, or make any
     increases, extensions, rearrangements, amendments, supplements, or other
     modifications to the Junior Debt, the effect of which is to (i) increase
     the maximum principal amount of the Junior Debt or rate of interest on any
     of the Junior Debt, (ii) accelerate or shorten the dates upon which
     payments of principal or interest on the Junior Debt are due, (iii) change
     in a manner adverse to Company or any Subsidiary, or add, any event of
     default or any covenant with respect to the Junior Debt, (iv) change any
     put, redemption or prepayment provisions of the Junior Debt, or (v) alter
     the subordination provisions with respect to the Junior Debt, including,
     without limitation, subordinating the Junior Debt to any other debt.

          (c) Notwithstanding anything herein to the contrary, (i) the Junior
     Creditors may file proofs of claim against the Company in any Proceeding
     involving the Company, (ii) the Junior Creditors may at any time and from
     time to time convert all or any portion of the Junior Notes into common
     stock of the Company in accordance with the terms thereof and (iii) the
     Junior Creditors may accrue interest at the default rate specified in the
     Note Purchase Agreement, or otherwise give notices or file suits, actions
     or proceedings, and the Company may agree to tolling agreements, to prevent
     the running of the relevant statute of limitations, but no Junior Creditor
     may receive any property or payment on account of any such suit, action or
     proceeding until the Senior Debt has been irrevocably paid in full.

          2.6 Incorrect Payments. If any payment or distribution on account of
     the Junior Debt not permitted to be made by the Company or any Subsidiary
     or received by a Junior Creditor under this Agreement is received by such
     Junior Creditor before all outstanding Senior Debt has been irrevocably
     paid in full, such payment or distribution shall not be commingled with any
     asset of such Junior Creditor, shall be held in trust by such Junior
     Creditor for the

                                      D-5

<PAGE>

benefit of Lenders and shall be immediately paid over to Agent, or its
designated representative, in the form received (together with any necessary
endorsements) for application (in accordance with the Credit Agreement) to the
Senior Debt until all outstanding Senior Debt has been irrevocably paid in full.

     2.7 Sale, Transfer, etc. No Junior Creditor shall sell, assign or otherwise
transfer all or any portion of the Junior Debt or any Junior Debt Document
unless prior to the consummation of any such action, the transferee thereof
shall execute and deliver to Agent an agreement substantially identical to this
Agreement, providing for the continued subordination and forbearance of the
Junior Debt to the Senior Debt as provided herein and for the continued
effectiveness of all of the rights of the Senior Creditors arising under this
Agreement. Any failure to execute or deliver any such agreement shall make any
attempted sale, assignment or other transfer of any portion of the Junior Debt
or any Junior Debt Document void ab initio. The subordination effected hereby
shall survive any sale, assignment, pledge, disposition or other transfer of all
or any portion of the Junior Debt, and the terms of this Agreement shall be
binding upon the successors and assigns of such Junior Creditor, as provided in
Section 10 below.

     2.8 Legends. The Junior Creditors shall cause all Junior Debt to be
evidenced by a note, debenture, instrument, or other writing evidencing the
Junior Debt and will inscribe a statement or legend thereon to the effect that
such note, debenture, instrument, or other writing is subordinated to the Senior
Debt in favor of the Senior Creditors in the manner and to the extent set forth
in this Agreement.

     3. Modifications to Senior Debt. This is an irrevocable agreement of
subordination and the Senior Creditors may, without notice to any of the parties
hereto and without impairing or releasing the obligations of the Company, any
Subsidiary and the Junior Creditors hereunder, (a) create Senior Debt by
extending credit under the Credit Agreement; (b) change the terms of or increase
the amount of the Senior Debt by increasing, extending, rearranging, amending,
supplementing, or otherwise modifying any of the Loan Documents or other
instruments or agreements creating Senior Debt; (c) sell, exchange, release, or
otherwise deal with any collateral securing any Senior Debt; (d) release anyone,
including the Company, any Subsidiary or any guarantor, liable in any manner for
the payment or collection of any Senior Debt; (e) exercise or refrain from
exercising any rights against the Company or any Subsidiary or any other Person;
and (f) apply any sums received by any of the Senior Creditors, from whatever
source, to the payment of the Senior Debt; provided, however, that neither Agent
nor any of the Lenders shall (a) increase the Senior Debt to an amount greater
than the sum of the aggregate principal amount of Senior Debt outstanding on the
date hereof plus $2,000,000, reduced by the amount of any repayments and
prepayments thereof (it being understood that no amounts expended by any Senior
Creditor to preserve the value of, or otherwise protect, the Collateral, shall
be subject to, or included within, the foregoing limitations), (b) increase the
interest rate with respect to the Senior Debt by more than three hundred (300)
basis points from any interest rate specified in the Credit Agreement as in
effect on the date hereof, or (c) extend the final maturity of the Senior Debt
to a date later than June 30, 2007.

     4. Continued Effectiveness of this Agreement. The terms of this Agreement,
the subordination effected hereby, and the rights and the obligations of the
Junior Creditors, the

                                       D-6

<PAGE>

Company, the Subsidiaries, Agent and Lenders arising hereunder shall not be
affected, modified or impaired in any manner or to any extent by: (a) any
amendment or modification of or supplement to the Credit Agreement, any of the
other Loan Documents or any of the Junior Debt Documents, in each instance, to
the extent permitted herein; (b) the validity or enforceability of any of such
documents; or (c) any exercise or non-exercise of any right, power or remedy
under or in respect of the Senior Debt or the Junior Debt or any of the
instruments or documents referred to in clause (a) above. The Junior Creditors
and each other holder of Junior Debt hereby acknowledge that the provisions of
this Agreement are intended to be enforceable at all times, whether before the
commencement of, after the commencement of, in connection with or premised on
the occurrence of a Proceeding.

     5. Cumulative Rights, No Waivers. Each and every right, remedy and power
granted to Agent or Lenders hereunder shall be cumulative and in addition to any
other right, remedy or power specifically granted herein, in the Credit
Agreement or the other Loan Documents or now or hereafter existing in equity, at
law, by virtue of statute or otherwise, and may be exercised by Agent or
Lenders, from time to time, concurrently or independently and as often and in
such order as Agent or Lenders may deem expedient. Any failure or delay on the
part of Agent or Lenders in exercising any such right, remedy or power, or
abandonment or discontinuance of steps to enforce the same, shall not operate as
a waiver thereof or affect the rights of Agent or Lenders thereafter to exercise
the same, and any single or partial exercise of any such right, remedy or power
shall not preclude any other or further exercise thereof or the exercise of any
other right, remedy or power, and no such failure, delay, abandonment or single
or partial exercise of the rights of Agent or Lenders hereunder shall be deemed
to establish a custom or course of dealing or performance among the parties
hereto.

     6. Modification. Any amendment, modification or waiver of any provision of
this Agreement shall not be effective in any event unless the same is in writing
and signed by Agent, Company, the Subsidiaries and each Junior Creditor and then
such amendment, modification or waiver shall be effective only in the specific
instance and for the specific purpose given.

     7. Additional Documents and Actions. The Company, each Subsidiary and the
Junior Creditors at any time, and from time to time, after the execution and
delivery of this Agreement, will execute and deliver such further documents as
Agent reasonably may request that may be necessary in order to confirm the
subordination effected herein.

other communication required or permitted to be given shall be in writing
addressed to the respective party as set forth below and may be personally
served, telecopied or sent by overnight courier service or certified or

INTO A BUSINESS RELATIONSHIP, THAT EACH HAS RELIED ON THE WAIVER IN ENTERING
INTO THIS AGREEMENT AND THE LOAN DOCUMENTS AND THAT EACH WILL CONTINUE TO RELY

<PAGE>

the Senior Debt is rescinded or otherwise restored or returned by a Senior
Creditor to the Company or any Subsidiary by reason of any Proceedings, all as

Invalidated Senior Payment and such payments received by the Junior Creditors
have not been rescinded or otherwise restored or returned by the Senior
Creditors to the Company or any Subsidiary or paid over to the Senior Creditors,
the Junior Creditors hereby agree to pay over to the Senior Creditors the amount
of such payments so received by the Junior Creditors on or subsequent to such
date to the extent necessary to restore to the Senior Creditors the amount of
the Invalidated Senior Payment.

     20. Termination of Prior Subordination Agreement. The parties hereto
acknowledge and agree that, upon the execution, delivery and effectiveness of
this Agreement, that certain Subordination and Intercreditor Agreement dated as
of January 31, 2000 by and among the Company, Agent, Heller, Midwest and the
Persons party thereto as "Guarantors" is terminated and shall be of no further
force or effect.

     Section 2.     Exercise of Warrant.

     (a)  Subject to the terms and conditions hereof, this Warrant may be
exercised by the holder hereof then registered on the books of the Company, in
whole or in part, at any time on any Business Day on or after the opening of
business on the date hereof and prior to 11:59 P.M. New York Time on the
Expiration Date by (i) delivery of a written notice, in the form of the
subscription form attached as Exhibit A hereto (the "Exercise Notice"), of such
holder's election to exercise this Warrant, which notice shall specify the
number of Warrant Shares to be purchased, (ii) (A) payment to the Company of an
amount equal to the Warrant Exercise Price multiplied by the number of Warrant
Shares as to which this Warrant is being exercised (the "Aggregate Exercise
Price") or (B) by notifying the Company that this Warrant is being exercised
pursuant to a Cashless Exercise (as defined in Section 2(e), and (iii) if this
Warrant is

<PAGE>

being exercised with respect to all of the Warrant Shares for which it can then
be exercised, the surrender to a common carrier for overnight delivery to the
Company as soon as practicable following such date, this Warrant (or an
indemnification undertaking with respect to this Warrant in the case of its
loss, theft or destruction). In the event of any exercise of the rights
represented by this Warrant in compliance with this Section 2(a), the Company
shall on the third (3rd) Business Day (the "Warrant Share Delivery Date")
following the date of its receipt of the Exercise Notice, the Aggregate Exercise
Price (or notice of Cashless Exercise) and this Warrant (or an indemnification
undertaking with respect to this Warrant in the case of its loss, theft or
destruction) (the "Exercise Delivery Documents") (A) provided that the transfer
agent is participating in The Depository Trust Company ("DTC") Fast Automated
Securities Transfer Program and provided that the holder is eligible to receive
shares through DTC, upon the request of the holder of this Warrant, credit the
number of shares of Preferred Stock to which the holder is entitled to the
holder's balance account with DTC through its Deposit Withdrawal Agent
Commission system or (B) issue and deliver to the address specified in the
Exercise Notice, a certificate, registered in the name of the holder, for the
number of shares of Preferred Stock to which the holder is entitled. Upon
delivery of the Exercise Notice and Aggregate Exercise Price referred to in
clause (ii)(A) above or notification to the Company of a Cashless Exercise
referred to in Section 2(e), the holder of this Warrant shall be deemed for all
corporate purposes to have become the holder of record of the Warrant Shares
with respect to which this Warrant has been exercised, irrespective of the date
of delivery of this Warrant as required by clause (iii) above or the
certificates evidencing such Warrant Shares. In the case of a dispute as to the
determination of the arithmetic calculation of the Warrant Exercise Price and
the arithmetic calculation of the number of Warrant Shares, the Company shall
instruct the Transfer Agent to issue to the holder the number of shares of
Preferred Stock that is not disputed and shall transmit an explanation of the
disputed arithmetic calculations to the holder via facsimile within two (2)
Business Days of receipt of such holder's Exercise Notice or other date of
determination. If such holder and the Company are unable to agree upon the
determination of the arithmetic calculation of the Warrant Exercise Price and
the arithmetic calculation of the number of Warrant Shares within two (2)
Business Day of such disputed arithmetic calculation being transmitted to the
holder, then the Company shall within one (1) Business Day submit via facsimile
the disputed arithmetic calculations to the Company's independent, outside
accountant. Furthermore, in the event a Majority Interest, on the one hand, and
the Company, on the other hand, are unable to agree on the Fair Market Value in
accordance with the definition of Closing Bid Price, then the Company shall
submit as soon as reasonably practicable after it becomes apparent that the
parties do not agree as to the Fair Market Value, the disputed determination of
the Fair Market Value to an independent, reputable investment bank selected by
the Company and approved by a Majority Interest. The Company shall cause the
investment bank or the accountant, as the case may be, to perform the
determinations or calculations and notify the Company and the holders of the
Preferred Warrants of the results no later than two Business Days from the time
it receives the disputed determinations or calculations. Such investment bank's
or accountant's determination or calculation, as the case may be, shall be
binding upon all parties. Within one (1) Business Day of the accountant's
determination of the calculation of arithmetic calculation of the Warrant
Exercise Price and the arithmetic calculation of the number of Warrant Shares,
the Company shall deliver to the holder the balance of Preferred Stock that such
holder is entitled to as provided herein (such date also deemed to be a Warrant
Share Delivery Date) and any failure to do so will subject the Company to the
provisions of this Section 2(a).

<PAGE>

     (b)  Notwithstanding anything to the contrary set forth herein, upon
exercise of any portion of this Warrant in accordance with the terms hereof, the
holder of this Warrant shall not be required to physically surrender this
Warrant to the Company unless the full amount of Warrant Shares then represented
by the Warrant have been exercised. The Company shall maintain records showing
the Warrant Shares so exercised and the dates of such exercise or shall use such
other method, reasonably satisfactory to the holder, so as to account for the
number of Warrant Shares that are represented by the Warrant where the exercise
of the Warrant has occurred without the physical surrender of this Warrant.
Notwithstanding the foregoing, if any portion of this Warrant is converted as
aforesaid, thereafter, the holder may not transfer this Warrant unless the
holder first physically surrenders this Warrant to the Company, whereupon the
Company will forthwith issue and deliver to the holder a new Warrant of like
tenor, registered as the holder may request, representing in the aggregate the
remaining Warrant Shares represented by this Warrant. The holder and any
assignee, by acceptance of this Warrant or such new Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following exercise of
any portion of this Warrant, the number of Warrant Shares represented by this
Warrant may be less than the number of Warrant Shares set forth on the face
hereof. If a Warrant is delivered to the Company by a holder and the number of
Warrant Shares represented by the Warrant submitted for exercise is greater than
the number of Warrant Shares that have been exercised, then the Company shall,
as soon as practicable and in no event later than three (3) Business Days after
receipt of the Warrant (the "Warrant Delivery Date") and at its own expense,
issue and deliver to the holder a new Warrant representing the number of Warrant
Shares not converted.

     (c)  No fractional shares of Preferred Stock are to be issued upon the
exercise of this Warrant, but rather the number of shares of Preferred Stock
issued upon exercise of this Warrant shall be rounded up to the nearest whole
number.

     (d)  If the Company shall fail for any reason or for no reason to issue and
deliver to the holder within three (3) Business Days of receipt of the Exercise
Delivery Documents a certificate for the number of shares of Preferred Stock to
which the holder is entitled or to credit, at the holder's request, the holder's
balance account with DTC for such number of shares of Preferred Stock to which
the holder is entitled upon the holder's exercise of this Warrant or to issue a
new Warrant for the number of shares of Preferred Stock to which such holder is
entitled pursuant to Section 2(b) hereof, then the Company shall, in addition to
any other remedies under this Warrant or otherwise available to such holder, pay
as additional damages in cash to such holder on each day after the Warrant Share
Delivery Date that such exercise is not timely effected and/or each day after
the Warrant Delivery Date that such Warrant is not delivered, as the case may
be, in an amount equal to 0.5% of the sum of (i) the product of (A) the number
of shares of Preferred Stock not issued to the holder on or prior to the Warrant
Share Delivery Date and (B) the Closing Bid Price of the Preferred Stock on the
Warrant Share Delivery Date, in the case of the failure to deliver Preferred
Stock, and (ii) if the Company has failed to deliver a Warrant to the holder on
or prior to the Warrant Delivery Date, the product of (x) the number of shares
of Preferred Stock issuable upon exercise of the Warrant (without regard to any
limitations on conversions herein or elsewhere, including, but not limited to,
any limitations as a result of the actual number of shares of Preferred Stock
authorized for issuance by the Company) as of the Warrant Delivery Date, and (y)
the Closing Bid Price of the Preferred Stock on the Warrant Delivery Date, in
the case of the failure to deliver a Warrant. If for any reason the

<PAGE>

holder has not received all of the shares of Preferred Stock to which it is
entitled to prior to the tenth (10th) Business Day after the expiration of the
Warrant Share Delivery Date, then the holder, upon written notice to the
Company, may void its Exercise Notice with respect to, and retain or have
returned or restored as of the date of the Exercise Notice, as the case may be,
any Warrant Shares pursuant to such holder's Exercise Notice; provided that the
voiding of a holder's Exercise Notice shall not effect the Company's obligations
to make any payments which have accrued prior to the date of such notice
pursuant to this Section 2(d).

     (e)  Notwithstanding anything contained herein to the contrary, the holder
of this Warrant may, at its election exercised in its sole discretion, exercise
this Warrant in whole or in part and, in lieu of making the cash payment
otherwise contemplated to be made to the Company upon such exercise in payment
of the Aggregate Exercise Price, elect instead to receive upon such exercise the
"Net Number" of shares of Preferred Stock determined according to the following
formula (a "Cashless Exercise"):

     Net Number = (A X B) - (A X C) / B
     For purposes of the foregoing formula:
     A=   the total number of shares with respect to which this Warrant
          is then being exercised.
     B=   the Closing Bid Price of the Preferred Stock on the trading day
          immediately preceding the date of the Exercise Notice.
     C=   the Warrant Exercise Price then in effect for the applicable
          Warrant Shares at the time of such exercise.

     Section 3.     Covenants as to Preferred Stock. The Company hereby
covenants and agrees as follows:

     (a)  This Warrant is, and any Warrants issued in substitution for or
replacement of this Warrant will upon issuance be, duly authorized and validly
issued, not subject to any preemptive rights, and free from all taxes, liens,
security interests, charges, and other encumbrances with respect to the issuance
thereof, other than taxes in respect of any transfer occurring contemporaneously
with such issue.

     (b)  All Warrant Shares which may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued, fully paid
and nonassessable, and not subject to any preemptive rights, and free from all
taxes, liens, security interests, charges, and other encumbrances with respect
to the issuance thereof, other than taxes in respect of any transfer occurring
contemporaneously with such issue.

     (c)  During the period within which the rights represented by this Warrant
may be exercised, (i) the Company will at all times have authorized and reserved
at least (A) 100% of the number of shares of Preferred Stock needed to provide
for the exercise of the rights then represented by this Warrant and (B) 100% of
the number of shares of Common Stock needed to provide for the conversion of
such shares of Preferred Stock (and if there is ever an insufficient amount of
shares of Preferred Stock or Common Stock to provide for the exercise of the
rights represented by this Warrant, such event shall be an "Authorized Share
Failure"), the Company

<PAGE>

shall immediately take all action necessary to increase the Company's authorized
shares of Preferred Stock or Common Stock to an amount sufficient to accomplish
the holder's right of exercise hereunder) and, (ii) the Company will at all
times ensure that the Warrant Exercise Price of this Warrant is less than the
aggregate par value of the greater of (x) the par value of the Preferred Stock
issuable upon exercise of this Warrant and (y) the par value of the number of
shares of Common Stock issuable upon conversion of the Preferred Stock issuable
upon exercise of this Warrant (and if there is ever a time when such Warrant
Exercise Price is less that such amount, such event shall be a "Par Value
Failure"). Without limiting the generality of the foregoing sentence, as soon as
practicable after the date of the occurrence of an Authorized Share Failure, but
in no event later than 75 days after the occurrence of such Authorized Share
Failure, the Company shall hold a meeting of its stockholders for the
authorization of either an increase in the number of authorized shares of
Preferred Stock or Common Stock, as applicable, or a reverse stock split with
respect to such shares. In addition, without limiting the generality of the
foregoing, as soon as practicable after the date of the occurrence of a Par
Value Failure, but in no event later than 75 days after the occurrence of such
Par Value Failure, the Company shall hold a meeting of its stockholders for the
authorization of a reduction in the par value of the Common Stock or Preferred
Stock, as appropriate. In connection with such meeting, the Company shall
provide each stockholder with a proxy statement and shall use its best efforts
to solicit its stockholders' approval of such increase in authorized shares of
Preferred Stock or Common Stock, reverse stock split or reduction in par value,
as applicable, and to cause its board of directors to recommend to the
stockholders that they approve such proposal.

     (d)  The Company will not, by amendment of its Certificate of Incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities, or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Preferred Stock receivable upon
the exercise of this Warrant above the Warrant Exercise Price then in effect
(except as otherwise provided in Section 3(c) above, and (ii) will take all such
actions as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Preferred Stock upon
the exercise of this Warrant.

     Section 4.     Taxes. The Company shall pay any and all taxes which may be
payable with respect to the issuance and delivery of Warrant Shares upon
exercise of this Warrant.

     Section 5.     Warrant Holder Not Deemed a Stockholder; Notice of Corporate
Action. Except as otherwise specifically provided herein, no holder, as such, of
this Warrant shall be entitled to vote or receive dividends or be deemed the
holder of shares of the Company for any purpose, nor shall anything contained in
this Warrant be construed to confer upon the holder hereof, as such, any of the
rights of a stockholder of the Company or any right to vote, give or withhold
consent to any corporate action (whether any reorganization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise),
receive notice of meetings, receive dividends or subscription rights, or
otherwise, prior to the issuance to the

<PAGE>

holder of this Warrant of the Warrant Shares which he, she, or it is then
entitled to receive upon the due exercise of this Warrant. In addition, nothing
contained in this Warrant shall be construed as imposing any liabilities on such
holder to purchase any securities (upon exercise of this Warrant or otherwise)
or as a stockholder of the Company, whether such liabilities are asserted by the
Company or by creditors of the Company. Notwithstanding this Section 5, the
Company will provide the holder of this Warrant with copies of the same notices
and other information given to the stockholders of the Company generally,
contemporaneously with the giving thereof to the stockholders. Furthermore, so
long as this Warrant has not been exercised in full:

               (A)  Immediately upon any adjustment of the Exercise Price or the
number of shares of Preferred Stock issuable upon exercise of this Warrant, the
Company will give written notice thereof to the holder of such adjustment and a
certificate of a firm of independent public accountants of recognized national
standing selected by the Board of Directors of the Company (who shall be
appointed at the Company's expense and who may be the independent public
accountants regularly employed by the Company) setting forth the number of
shares of Preferred Stock and the Exercise Price of such shares after such
adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth the computation by which such adjustment was made.

               (B)  The Company will give written notice to the holder at least
twenty (20) Business Days prior to the date on which the Company closes its
books or takes a record (I) with respect to any dividend or distribution upon
the Preferred Stock or the Common Stock, (II) with respect to any pro rata
subscription offer to holders of Preferred Stock or the Common Stock or (III)
for determining rights to vote with respect to any Organic Change (as defined in
Section 9(b)), dissolution or liquidation, provided that such information shall
be made known to the public prior to or in conjunction with such notice being
provided to such holder.

               (C)  The Company will also give written notice to holder at least
twenty (20) Business Days prior to the date on which any Organic Change,
dissolution or liquidation will take place, provided that such information shall
be made known to the public prior to or in conjunction with such notice being
provided to such holder.

     Section 6.     Representations of Holder. The holder of this Warrant, by
the acceptance hereof, represents that it is acquiring this Warrant and the
Warrant Shares for its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution of
this Warrant or the Warrant Shares, except pursuant to sales registered or
exempted under the Securities Act; provided, however, that by making the
representations herein, the holder does not agree to hold this Warrant or any of
the Warrant Shares for any minimum or other specific term and reserves the right
to dispose of this Warrant and the Warrant Shares at any time in accordance with
or pursuant to a registration statement or an exemption under the Securities
Act. The holder of this Warrant further represents, by acceptance hereof, that,
as of this date, such holder is an "accredited investor" as such term is defined
in Rule 501(a)(3) of Regulation D promulgated by the Securities and Exchange
Commission under the Securities Act (an "Accredited Investor").

     Section 7.     Ownership and Transfer.

<PAGE>

     (a)  Warrant Register. The Company shall maintain at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee. The
Company may treat the person in whose name any Warrant is registered on the
register as the owner and holder thereof for all purposes, notwithstanding any
notice to the contrary, but in all events recognizing any transfers made in
accordance with the terms of this Warrant.

     (b)  Transferability and Negotiability of Warrant. Title to this Warrant
may be transferred by endorsement (by the holder hereof executing the Assignment
Form attached hereto as Exhibit B) and delivery in the same manner as negotiable
instruments transferable by endorsement and delivery.

     (c)  Exchange of Warrant Upon a Transfer. This Warrant shall be
transferable by the holder hereof to (i) any Person subject only to the
restrictions set forth in the legend on the first page of this Warrant or (ii)
any of its Affiliates. On surrender of this Warrant for exchange, properly
endorsed on the Assignment Form and subject to the provisions hereof with
respect to compliance with the Securities Act, the Company at its expense shall
issue to or on the order of such holder a new warrant or warrants of like tenor,
in the name of such holder or as such holders (on payment by the holder of any
applicable transfer taxes) may direct, exercisable for the number of shares of
Preferred Stock issuable upon the exercise hereof.

     Section 8.     Adjustment of Warrant Exercise Price and Number of
Shares. The Warrant Exercise Price and the number of shares of Preferred Stock
issuable upon exercise of this Warrant shall be adjusted from time to time as
follows:

     (a)  Adjustment of Warrant Exercise Price upon Subdivision or Combination
of Preferred Stock. If the Company at any time after the date of issuance of
this Warrant subdivides (by any stock split, stock dividend, recapitalization or
otherwise) its outstanding shares of Preferred Stock into a greater number of
shares, the Warrant Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of shares of
Preferred Stock obtainable upon exercise of this Warrant will be proportionately
increased. If the Company at any time after the date of issuance of this Warrant
combines (by combination, reverse stock split or otherwise) its outstanding
shares of Preferred Stock into a smaller number of shares, the Warrant Exercise
Price in effect immediately prior to such combination will be proportionately
increased and the number of shares of Preferred Stock obtainable upon exercise
of this Warrant will be proportionately decreased. The increases and reductions
provided for in this Section 8(a) will be made with the intent and, as nearly as
practicable, the effect that neither the percentage of the total equity of the
Company obtainable on exercise of the Warrant nor the price payable for such
percentage upon such exercise will be affected by any event described in this
Section 8(a). Any adjustment under this Section 8(a) shall become effective at
the close of business on the date the subdivision or combination becomes
effective.

     (b)  Conversion of Preferred Stock. Should all of the Preferred Stock be,
or if outstanding would be, at any time prior to the expiration of this Warrant
or any portion thereof, converted into shares of Common Stock in accordance with
the conversion terms of such

<PAGE>

Preferred Stock, then this Warrant shall become immediately exercisable for that
number of shares of Common Stock equal to the number of shares of the Common
Stock that would have been received if this Warrant had been exercised in full
and the Preferred Stock received thereupon had been simultaneously converted
immediately prior to such event, and the Warrant Exercise Price shall
immediately be adjusted to equal the quotient obtained by dividing (x) the
aggregate Warrant Exercise Price of the maximum number of shares of Preferred
Stock for which this Warrant was exercisable immediately prior to such
conversion, by (y) the number of shares of Common Stock for which this Warrant
is exercisable immediately after such conversion.

     (c)  Distribution of Securities. If securities of the Company or securities
of any subsidiary of the Company are distributed pro rata to holders of any or
all of the Company's Securities, such number of securities will be distributed
to the holder of this Warrant or its assignee upon exercise of its rights
hereunder as such Warrant holder or assignee would have been entitled to if this
Warrant had been exercised prior to such distribution, giving effect to all
adjustments called for by this Section 8. The provisions with respect to
adjustment of the Preferred Stock provided in this Section 8 will also apply to
the Securities of the Company and securities of any subsidiary to which the
Warrant holder or its assignee is entitled under this Section 8 (c).

     (d)  Certain Events. If any event occurs of the type contemplated by the
provisions of this Section 8 but not expressly provided for by such provisions,
then the Company's Board of Directors will make an appropriate adjustment in the
Warrant Exercise Price and the number of shares of Preferred Stock obtainable
upon exercise of this Warrant so as to protect the rights of the holders of the
Preferred Warrants.

     Section 9.     Purchase Rights; Reorganization, Reclassification,
Consolidation, Merger or Sale. (a) In addition to any adjustments pursuant to
Section 8 above, if at any time the Company grants, issues or sells any Options,
Convertible Securities or rights to purchase stock, warrants, securities or
other property pro rata to the record holders of any class of Common Stock (the
"Purchase Rights"), then the holder of this Warrant will be entitled to acquire,
upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which such holder could have acquired if such holder had held the number of
shares of Preferred Stock acquirable upon complete exercise of this Warrant
immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of Preferred Stock are to be determined for the grant,
issue or sale of such Purchase Rights.

     (b)  Any recapitalization, reorganization, reclassification, consolidation,
merger, sale of all or substantially all of the Company's assets to another
Person, conveyance to another Person of the property of the Company as an
entirety or substantially as an entirety or other transaction which is effected
in such a way that holders of Preferred Stock are entitled to receive (either
directly or upon subsequent liquidation) Capital Stock, securities or assets
with respect to or in exchange for Preferred Stock is referred to herein as an
"Organic Change." Prior to the consummation of, and as a condition to, any (i)
sale or other conveyance of all or substantially all of the Company's assets to
an acquiring Person or (ii) other Organic Change, the Company, or such other
successor or purchasing Person, as the case may be, shall make lawful and

<PAGE>

adequate provision whereby the holder of this Warrant shall have the right
thereafter to receive on exercise of such Warrant the kind and amount of
securities and property receivable upon such Organic Change by a holder of the
number of securities issuable upon exercise of such Warrant immediately prior to
such Organic Change. The above provisions of this Section 9(b) shall similarly
apply to successive Organic Changes.

     Section 10.    Lost, Stolen, Mutilated or Destroyed Warrant. If this
Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on
receipt of an indemnification undertaking (or in the case of a mutilated
Warrant, the Warrant), issue a new Warrant of like denomination and tenor as
this Warrant so lost, stolen, mutilated or destroyed.

     Section 11.    Notices. Service of all notices under this Warrant shall be
sufficient and considered given if in writing and delivered personally or sent
by certified United States mail, return receipt requested, with postage paid
thereon, to the following address:

     To holder:     ____________________________

date shown on the return receipt. Either party may, by notice given at any time
or from time to time, require subsequent notices to be given to another
individual person, whether a partner, an officer, or a representative, or to a
different address, or both. Notices given before actual receipt of notice of
such change shall not be invalidated by the change.

     Section 12.    Registration Rights. If the holder hereof is a party to, or
an assignee of rights under, that certain Registration Rights Agreement, dated
as of July 19, 2002, by and among the Company and the Persons who are
signatories thereto, such holder shall be entitled to include with such holder's
registrable securities any shares of Preferred Stock or other securities
received upon exercise of this Warrant, all on the terms and conditions as set
forth in the Registration Rights Agreement.

     Section 13.    Amendments. This Warrant and any term hereof may be changed,
waived, discharged, or terminated only by an instrument in writing signed by the
Company and a Majority Interest; provided, however, that no amendment,
modification or waiver can be effected if, by its terms, such amendment,
modification or waiver adversely affects one holder without having the same
adverse effect on all other holders without the prior written consent of the
adversely affected holder.

<PAGE>

     Section 14.    Date. The date of this Warrant is July 19, 2002 (the
"Warrant Date"). This Warrant, in all events, shall be wholly void and of no
effect after the close of business on the Expiration Date, except that
notwithstanding any other provisions hereof, the provisions of Section 7 shall
continue in full force and effect after such date as to any Warrant Shares or
other securities issued upon the exercise of this Warrant.

     Section 15.    Descriptive Headings; Governing Law. The descriptive
headings of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. The corporate
laws of the State of Delaware shall govern all issues concerning the relative
rights of the Company and its stockholders. All other questions concerning the
construction, validity, enforcement and interpretation of this Warrant shall be
governed by the internal laws of the State of Delaware, without giving effect to
any choice of law or conflict of law provision or rule (whether of the State of
Delaware or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Delaware.
