            (a) Procedure for Borrowing. Each Borrowing shall be made upon
Borrower's irrevocable request therefor delivered to Agent (which notice must be
received by Agent no later than 10:00 a.m. (New York time) on the Business Day
that is the requested Funding Date) specifying (i) the amount of such Borrowing,
and (ii) the requested Funding Date, which shall be a Business Day. Upon receipt
of each such notice, Agent shall promptly notify each Lender having a Commitment
to make the requested type of Advance and, subject to the terms and conditions
hereof, each Lender shall promptly remit its Pro Rata Share of the requested
Advance to Agent. If and to the extent that Agent receives funds from such
Lenders on a timely basis, it shall remit such funds to Borrower by not later
than 4:00 p.m. (New York time) on the Funding Date; it being the express
understanding of the parties that Agent may, but shall not be obligated to,
advance funds to Borrower on behalf of the Lenders having a Commitment to make a
requested type of Advance and that the only parties having Commitments to make
Advances are Lenders as opposed to Agent (in its capacity as agent).

            (b) Disbursement of Funds. Agent, subject to the terms and
conditions herein, may, on behalf of the Lenders, disburse funds to Borrower for
Loans requested. If any Lender fails to pay the amount necessary to adjust such
Lender's actual Pro Rata Share pursuant to Section 2.3(c), Agent shall promptly
notify Borrower, and Borrower shall immediately repay such amount to Agent
(without duplication of amounts received by Agent from such Lender pursuant to
Section 2.3(d)) without set-off, counterclaim, or deduction of any kind together
with interest thereon, for each day from and including the date such amount was
to have been made available to Agent by such Lender to but excluding the date of
payment to Agent, at the interest rate then applicable under this Agreement with
respect to such Advance. Any repayment required pursuant to this Section 2.3(b)
shall be without premium or penalty. Nothing in this Section 2.3(b) or elsewhere
in this Agreement or the other Loan Documents, including the provisions of
Section 2.3(c), shall be deemed to require Agent to advance funds on behalf of
any Lender or to relieve any Lender from its obligation to fulfill its
commitments hereunder or to prejudice any rights that Agent or Borrower may have
against any Lender as a result of any default by such Lender hereunder.
   31
            (c) Settlements.

                        (i)   The Revolving Facility Usage may fluctuate from
day to day through Agent's disbursement of funds to, and receipt of funds from,
Borrower. In order to minimize the frequency of transfers of funds between Agent
and each Lender, at Agent's sole option, Advances and payments may be settled
among Agent and Lenders according to the procedures described in this Section
2.3(c). These procedures notwithstanding, each Lender's obligation to fund its
portion of any Advances made by Agent to Borrower will commence on the date such
Advances are made by Agent. Such payments will be made by such Lender without
set-off, counterclaim or reduction of any kind. Nothing in this Section or
elsewhere in this Agreement or the other Loan Documents, shall be deemed to
require Agent to advance funds on behalf of any Lender or to relieve any Lender
from its obligation to fulfill its commitments hereunder or to prejudice any
rights that Agent or Borrower may have against any Lender as a result of any
default by such Lender hereunder.

                        (ii) On the 2nd Business Day of each week, or more
frequently (including daily), if Agent so elects (each such day being a
"Settlement Date"), Agent will advise each Lender by telephone or telecopy of
the amount of each such Lender's Pro Rata Share of the Revolving Facility Usage
as of the close of business of the 2nd Business Day immediately preceding the
Settlement Date. In the event that payments are necessary to adjust such
Lender's actual Pro Rata Share of the Revolving Facility Usage as of any
Settlement Date to equal the amount of such Lender's required Pro Rata Share of
the Revolving Facility Usage, the party from which such payment is due will pay
the other, in same day funds, by wire transfer to the other's account not later
than 1:00 p.m. (New York time) on the Business Day immediately following the
Settlement Date.

            (d) Availability of Lender's Pro Rata Share.

                        (i)   Unless Agent shall have received notice from a
Lender prior to a Funding Date that such Lender will not make available its Pro
Rata Share of an Advance requested by Borrower, Agent may assume that such
Lender will make such amount available to Agent on the Business Day following
the next Settlement Date. If a Lender does not in fact make its Pro Rata Share
available to the Agent on such date, then such Lender agrees to pay to Agent
forthwith on demand such amount (without duplication of amounts received from
Borrower pursuant to Section 2.5(b)) without set-off, counterclaim or deduction
of any kind, together with interest thereon, for each day from and including the
date such amount was to have been made available to Borrower to but excluding
the date of payment to Agent, at the then prevailing federal funds rate as most
recently announced from time to time by the Federal Reserve Board. Until any
such amount (with interest thereon as aforesaid) is paid to Agent, Agent shall
not be obligated to remit to such defaulting Lender any payment made by Borrower
to Agent with respect to any Loan or any fees or other payments with respect
thereto nor shall Agent be obligated to remit to such defaulting Lender its Pro
Rata Share of Collections and other proceeds in respect of Collateral.

                        (ii) Nothing contained in this Section 2.3(d) will be
deemed
   32
to relieve a Lender of its obligation to fulfill its commitments or to prejudice
any rights Agent or Borrower may have against such Lender as a result of any
such default by such Lender under this Agreement.

            (e) Return of Payments

                        (i)   If Agent pays an amount to a Lender under this
Agreement in the belief or expectation that a related payment has been or will
be received by Agent from Borrower and such related payment is not received by
Agent, then Agent will be entitled to recover such amount from such Lender
without set-off, counterclaim or deduction of any kind together with interest
thereon, for each day from and including the date such amount is made available
by Agent to such Lender to but excluding the date of repayment to Agent, at the
then prevailing federal funds rate as most recently announced from time to time
by the Federal Reserve Board, and such payment to such Lender shall be deemed to
not have been made.

                        (ii) If Agent determines at any time that any amount
received by Agent under this Agreement must be returned to Borrower or paid to
any other person pursuant to any requirement at law, court order or otherwise,
then, notwithstanding any other term or condition of this Agreement, Agent will
not be required to distribute any portion thereof to any Lender. In addition,
each Lender will repay to Agent on demand any portion of such amount that Agent
has distributed to such Lender, together with interest at such rate, if any, as
Agent is required to pay to Borrower or such other Person, without set-off,
counterclaim or deduction of any kind.

            (f) Lenders' Failure to Perform. It is understood that (i) no Lender
shall be responsible for any failure by any other Lender to perform its
obligation to make any Advances hereunder, nor shall any Commitment of any
Lender be increased or decreased as a result of any failure by any other Lender
to perform its obligation to make any Advances hereunder, and (ii) no failure by
any Lender to perform its obligation to make any Advances hereunder shall excuse
any other Lender from its obligation to make any Advances hereunder.

            (g) Replacement of Defaulting Lender.

                        (i)   If any Lender fails to perform its obligation to
make any Advance hereunder (a "Defaulting Lender"), and as a result of such
failure to perform (A) Borrower does not receive the total amount of an Advance
requested by Borrower, or (B) Borrower is required to repay Agent for amounts
received by Borrower and not paid by such Defaulting Lender, then Borrower may,
upon at least 5 Business Days' prior irrevocable notice to each of such Lender,
Agent, and S&A Agent, permanently replace such Defaulting Lender with one or
more Eligible Transferees (collectively, the "Replacement Lenders"). The notice
from Borrower to replace a Lender shall specify an effective date for such
replacement, which date shall not be later than the tenth Business Day after the
date such notice is given. Prior to such effective date, such Defaulting Lender
and each Replacement Lender shall execute an Assignment and Acceptance
Agreement. The replacement of such Lender shall
   33
be made in accordance with the terms of Section 15.1.

                        (ii) Prior to such effective date, such Defaulting
Lender and each Replacement Lender shall execute an Assignment and Acceptance
Agreement. Until such time as the Replacement Lenders shall have acquired all of
the Obligations, the Commitments, and the other rights and obligations of such
Defaulting Lender hereunder and under the other Loan Documents, such Defaulting
Lender shall remain obligated to make such Defaulting Lender's Pro Rata Share of
Tranche A Advances and Tranche B Advances.

                        (iii) Nothing contained in this Section 2.3(g) shall
(A) increase any Lender's Tranche A Commitment or Tranche B Commitment, or (B)
be deemed to prejudice any rights Agent or Borrower may have against such
Defaulting Lender as a result of such Defaulting Lender's failure to perform
under this Agreement.

2.4   Payments.

            (a) Payments by Borrower.

                        (i)   All payments to be made by Borrower shall be
made without set-off, recoupment, deduction, or counterclaim, except as
otherwise required by law. Except as otherwise expressly provided herein, all
payments by Borrower shall be made to Agent for the account of the Lender Group
at Agent's address set forth in Section 12, and shall be made in immediately
available funds, no later than 2:00 p.m. (New York time) on the date specified
herein. Any payment received by Agent later than 2:00 p.m. (New York time), at
the option of Agent, shall be deemed to have been received on the following
Business Day and any applicable interest or fee shall continue to accrue until
such following Business Day.

                        (ii)  Whenever any payment is due on a day other than
a Business Day, such payment shall be made on the following Business Day, and
such extension of time shall in such case be included in the computation of
interest or fees, as the case may be.

                        (iii) Unless Agent receives notice from Borrower prior
to the date on which any payment is due to the Lenders that Borrower will not
make such payment in full as and when required, Agent may assume that Borrower
has made such payment in full to Agent on such date in immediately available
funds and Agent may (but shall not be so required), in reliance upon such
assumption, distribute to each Lender on such due date an amount equal to the
amount then due such Lender. If and to the extent Borrower has not made such
payment in full to Agent, each Lender shall repay to Agent on demand such amount
distributed to such Lender, together with interest thereon at the Base Rate for
each day from the date such amount is distributed to such Lender until the date
repaid.

            (b) Apportionment, Application, and Reversal of Payments.
   34
                        (i)   All payments shall be remitted to Agent.  So
long as no Event of Default has occurred and is continuing, except as otherwise
provided with respect to defaulting Lenders, such payments shall be applied:
first, ratably, to pay any fees or expense reimbursements then due to Agent or
S&A Agent from Borrower under this Agreement or the other Loan Documents
(collectively, "Reimbursable Agent Expenses"); second, to pay any fees or
expense reimbursements then due to the Lenders from Borrower under this
Agreement or the other Loan Documents (collectively, "Reimbursable Lender
Expenses"); third, to pay interest due in respect of all Advances; fourth, to
pay the outstanding principal of Tranche B Advances; fifth, to pay the
outstanding principal of Tranche A Advances; and sixth, ratably to pay any other
Obligations due to Agent, S&A Agent, or any Lender by Borrower.

                        (ii)  Upon the occurrence and during the continuation
of an Event of Default, except as otherwise provided with respect to defaulting
Lenders, all Collections and other proceeds in respect of Collateral shall be
applied: first, ratably, to pay Reimbursable Agent Expenses; second, to pay the
Reimbursable Lender Expenses; third, to pay interest due in respect of all
Tranche A Advances; fourth, to pay the outstanding principal of all Tranche A
Advances; fifth, to pay interest due in respect of all Tranche B Advances;
sixth, to pay the outstanding principal of Tranche B Advances; and seventh,
ratably to pay any other Obligations due to Agent, S&A Agent, or any Lender by
Borrower.

                        (iii) All Collections applied pursuant to Subsections
(i) or (ii) above shall, within each category of application, be apportioned
ratably among those Lenders having a Pro Rata Share of the Tranche A Advances or
of the Tranche B Advances, as applicable, to which such amounts are to be
applied (other than fees designated for the sole and separate account of Agent
or S&A Agent).

                        (iv) If Agent determines at any time that any amount
received by Agent under this Agreement must be returned to Borrower or paid to
any other Person pursuant to any requirement at law, court order or otherwise,
then, notwithstanding any other term or condition of this Agreement, Agent will
not be required to distribute any portion thereof to any Lender. In addition,
each Lender will repay to Agent on demand any portion of such amount that Agent
previously has distributed to such Lender, together with interest at such rate,
if any, as Agent is required to pay to Borrower or such other Person, without
set-off, counterclaim or deduction of any kind.

2.5   Overadvances.

              If, at any time or for any reason, the amount of Obligations owed
by Borrower to the Lender Group pursuant to Sections 2.1 and 2.2 is greater than
either the Dollar or percentage limitations set forth in Sections 2.1 or 2.2,
(an "Overadvance"), Borrower shall pay to Agent, in cash, the amount of such
excess, without premium or penalty, which amount shall be used by Agent to
reduce the Obligations in accordance with the priority set forth in Section
2.4(b). If such Overadvance is caused by Agent's exercise of its
   35
discretionary right to (a) make payments on behalf of Borrower and to charge
such payments to Borrower's Loan Account, or (b) to adjust the Borrowing Base or
Dilution Reserve, then, in either case, Agent shall give Borrower notice of such
Overadvance and Borrower shall make such payment to Agent within 5 Business Days
after Borrower's receipt of such notice; otherwise such payment by Borrower to
Agent shall be made immediately upon the occurrence of the Overadvance. In
connection with any such required notice, Agent shall endeavor to provide
Borrower with reasonable detail concerning any adjustments to the Borrowing Base
or Dilution Reserve that created or contributed to such Overadvance.

2.6   Interest:  Rates, Payments, and Calculations.

            (a) Interest Rate. Except as provided in clause (c) below, all
Obligations shall bear interest at a per annum rate of 1 percentage point above
the Base Rate.

            (b) [intentionally omitted]

            (c) Default Rate. Upon the occurrence and during the continuation of
an Event of Default, all Obligations shall bear interest at a per annum rate
equal to 3 percentage points above the per annum rate otherwise applicable
thereto as set forth in Section 2.6(a).

            (d) [intentionally omitted]

            (e) Payments. Interest payable hereunder shall be due and payable,
in arrears, on the first day of each month during the term hereof. Borrower
hereby authorizes Agent, at its option, without prior notice to Borrower, to
charge such interest, all Lender Group Expenses (as and when incurred), the fees
and charges provided for in Section 2.11 (as and when accrued or incurred), and
all installments or other payments due under any Loan Document to Borrower's
Loan Account, which amounts thereafter shall accrue interest at the rate then
applicable to Advances hereunder. Any interest not paid when due shall be
compounded and shall thereafter accrue interest at the rate then applicable to
Advances hereunder.

            (f) Computation. In the event the Base Rate is changed from time to
time hereafter, the applicable rates of interest hereunder automatically and
immediately shall be increased or decreased by an amount equal to such change in
the Base Rate. All interest and fees chargeable under the Loan Documents shall
be computed on the basis of a 360 day year for the actual number of days
elapsed.

            (g) Intent to Limit Charges to Maximum Lawful Rate. In no event
shall the interest rate or rates payable under this Agreement, plus any other
amounts paid in connection herewith, exceed the highest rate permissible under
any law that a court of competent jurisdiction shall, in a final determination,
deem applicable. Borrower and the Lender Group, in executing and delivering this
Agreement, intend legally to agree upon the rate or rates of interest and manner
of payment stated within it; provided, however, that, anything contained herein
to the contrary notwithstanding, if said rate or rates of interest or
   36
manner of payment exceeds the maximum allowable under applicable law, then, ipso
facto as of the date of this Agreement, Borrower is and shall be liable only for
the payment of such maximum as allowed by law, and payment received from
Borrower in excess of such legal maximum, whenever received, shall be applied to
reduce the principal balance of the Obligations to the extent of such excess.

2.7   Collection of Accounts.

            (a) Borrower shall at all times maintain the lockboxes or similar
arrangement (the "Lockboxes") currently in place between Borrower and FNB. The
parties hereto agree that from and after the Closing Date, any and all
agreements between Borrower and FNB with respect to the Lockboxes (collectively,
the "Lockbox Agreements") shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect that FNB is a party to the Lockbox
Agreements in FNB's capacity as Agent. Borrower, Agent, and FNB shall open and
maintain the Lockbox Account for the deposit of Collections.

            (b) Borrower shall, immediately after the Closing Date, (a) instruct
all Account Debtors of Borrower to remit all Collections in respect thereof to
such Lockboxes, and (b) deposit all Collections in respect of Accounts received
by Borrower immediately upon receipt in to the Lockbox Accounts. Borrower agrees
that all Collections and other amounts received by Borrower from any Account
Debtor immediately upon receipt shall be deposited into the Lockbox Account.

            (c) All amounts received in the Lockbox Account shall be wired each
Business Day into the Designated Account; provided, however, that upon the
occurrence and during the continuance of an Event of Default, all amounts
received in the Lockbox Account shall be wired each Business Day into an account
(the "Agent Account") maintained by Agent at a depositary selected by Agent.

2.8   Crediting Payments; Application of Collections.

            The receipt of any Collections by Agent (whether from transfers to
Agent by the Lockbox Banks pursuant to the Lockbox Agreements or otherwise)
shall not be considered a payment on account unless such Collection item is a
wire transfer of immediately available federal funds and is made to the Agent
Account or unless and until such Collection item is honored when presented for
payment. Should any Collection item received by Agent not be honored when
presented for payment, then Borrower shall be deemed not to have made such
payment. Anything to the contrary contained herein notwithstanding, any
Collection item shall be deemed received by Agent only if it is received into
the Agent Account on a Business Day on or before 2:00 p.m. New York time. If any
Collection item is received into the Agent Account on a non-Business Day or
after 2:00 p.m. New York time on a Business Day, it shall be deemed to have been
received by Agent as of the opening of business on the immediately following
Business Day.

2.9   Designated Account.
   37
   
    


            Agent and the Lenders are authorized to make the Advances under this
Agreement based upon telephonic or other instructions received from anyone
reasonably believed by Agent to be an Authorized Person, or without instructions
if pursuant to Section 2.6(e). Borrower agrees to establish and maintain the
Designated Account with the Designated Account Bank for the purpose of receiving
the proceeds of the Advances requested by Borrower and made by Agent or the
Lenders hereunder. Unless otherwise agreed by Agent and Borrower, any Advance
requested by Borrower and made by hereunder shall be made to the Designated
Account.

2.10  Maintenance of Loan Account; Statements of Obligations.

            Agent shall maintain an account on its books in the name of Borrower
(the "Loan Account") on which Borrower will be charged with all Advances made by
Agent or the Lenders to Borrower or for Borrower's account, including, accrued
interest, Lender Group Expenses, and any other payment Obligations of Borrower.
In accordance with Section 2.8, the Loan Account will be credited with all
payments received by Agent from Borrower or for Borrower's account, including
all amounts received in the Agent Account from any Lockbox Bank. Agent shall
render statements regarding the Loan Account to Borrower, including principal,
interest, fees, and including an itemization of all charges and expenses
constituting Lender Group Expenses owing, and such statements shall be
conclusively presumed to be correct and accurate and constitute an account
stated between Borrower and the Lender Group unless, within 60 days after
receipt thereof by Borrower, Borrower shall deliver to Agent written objection
thereto describing the error or errors contained in any such statements.

2.11  Fees.

            Borrower shall pay to the following fees, which fees shall be
non-refundable when paid:


   
            (a) Unused Line Fees. Payable in arrears and fully earned on the
first day of each month during the term of this Agreement, (i) for the ratable
benefit of the Tranche A Lenders, an unused line fee in an amount equal to 0.5%
per annum times the Average Unused Portion of the Maximum Tranche A Amount, and
(ii) for the ratable benefit of the Tranche B Lenders, an unused line fee in an
amount equal to 0.5% per annum times the Average Unused Portion of the Maximum
Tranche B Amount.

            For the sole and separate accounts of Agent or S&A Agent, as
applicable, (i) a fee of $650 per day per examiner, plus out-of-pocket expenses
for each financial analysis and examination (i.e., audits) of Borrower performed
pursuant to Section 4.6 by the respective personnel employed by Agent, or S&A
Agent, as applicable, and (ii) the actual charges paid or incurred by Agent or
S&A Agent, as applicable, if it elects to employ the services of one or more

to employ the services of one or more third Persons to perform an enterprise

9.1   Rights and Remedies.

            Upon the occurrence, and during the continuation, of an Event of
Default, the Required Lenders (at their election but without notice of their
election and without demand) may, except to the extent otherwise expressly
provided or required below, authorize and instruct Agent to do any one or more
of the following on behalf of the Lender Group (and Agent, acting upon the
instructions of the Required Lenders, shall do the same on behalf of the Lender
Group so long as Agent does not reasonably believe such conduct to be unlawful),
all of which are authorized by Borrower:

            (a) Declare all Obligations, whether evidenced by this Agreement, by
any of the other Loan Documents, or otherwise, immediately due and payable;

            (b) Cease advancing money or extending credit to or for the benefit
of Borrower under this Agreement, under any of the Loan Documents, or under any
other agreement between Borrower and the Lender Group;

            (c) Terminate this Agreement and any of the other Loan Documents as
to any future liability or obligation of the Lender Group, but without affecting
Agent's rights and security interests, for the benefit of the Lender Group, in
the Collateral and without affecting the Obligations;

            (d) Settle or adjust disputes and claims directly with Account
Debtors for amounts and upon terms which Agent considers advisable, and in such
cases, Agent will credit Borrower's Loan Account with only the net amounts
received by Agent in payment of
   62
such disputed Accounts after deducting all Lender Group Expenses incurred or
expended in connection therewith;

            (e) [intentionally omitted];

            (f) Without notice to or demand upon Borrower or any guarantor, make
such payments and do such acts as Agent reasonably considers necessary to
protect its security interests in the Collateral. Borrower agrees to assemble
the Collateral if Agent so requires, and to make the Collateral available to
Agent as Agent may designate. Borrower authorizes Agent to enter the premises
where the Collateral is located, to take and maintain possession of the
Collateral, or any part of it, and to pay, purchase, contest, or compromise any
encumbrance, charge, or Lien that in Agent's determination appears to conflict
with the Agent's Liens and to pay all expenses incurred in connection therewith.
With respect to any of Borrower's owned or leased premises, Borrower hereby
grants Agent a license to enter into possession of such premises and to occupy
the same, without charge, for up to 120 days in order to exercise any of the
Lender Group's rights or remedies provided herein, at law, in equity, or
otherwise;

            (g) Without notice to Borrower (such notice being expressly waived),
and without constituting a retention of any collateral in satisfaction of an
obligation (within the meaning of Section 9-505 of the Code), set off and apply
to the Obligations any and all (i) balances and deposits of Borrower held by the
Lender Group (including any amounts received in the Lockbox Account), or (ii)
indebtedness at any time owing to or for the credit or the account of Borrower
held by the Lender Group;

            (h) Hold, as cash collateral, any and all balances and deposits of
Borrower held by the Lender Group, and any amounts received in the Lockbox
Account, to secure the full and final repayment of all of the Obligations;

            (i) Ship, reclaim, recover, store, finish, maintain, repair, prepare
for sale, advertise for sale, and sell (in the manner provided for herein) the
Collateral. Borrower hereby grants to Agent a license or other right to use,
without charge, Borrower's labels, patents, copyrights, rights of use of any
name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the Collateral,
in completing production of, advertising for sale, and selling any Collateral
and Borrower's rights under all licenses and all franchise agreements shall
inure to the Lender Group's benefit;

            (j) Sell the Collateral at either a public or private sale, or both,
by way of one or more contracts or transactions, for cash or on terms, in such
manner and at such places (including Borrower's premises) as Agent determines is
commercially reasonable. It is not necessary that the Collateral be present at
any such sale;

            (k) Agent shall give notice of the disposition of the Collateral as
follows:

                 (i) Agent shall give the applicable Borrower and each holder of
a
   63
            security interest in the Collateral who has filed with Agent a
            written request for notice, a notice in writing of the time and
            place of public sale, or, if the sale is a private sale or some
            other disposition other than a public sale is to be made of the
            Collateral, then the time on or after which the private sale or
            other disposition is to be made;

                 (ii) The notice shall be personally delivered or mailed,
            postage prepaid, to such Borrower as provided in Section 12, at
            least 15 days before the date fixed for the sale, or at least 15
            days before the date on or after which the private sale or other
            disposition is to be made; no notice needs to be given prior to the
            disposition of any portion of the Collateral that is perishable or
            threatens to decline speedily in value or that is of a type
            customarily sold on a recognized market. Notice to Persons other
            than such Borrower claiming an interest in the Collateral shall be
            sent to such addresses as they have furnished to Agent;

                 (iii) If the sale is to be a public sale, Agent also shall give
            notice of the time and place by publishing a notice one time at
            least 15 days before the date of the sale in a newspaper of general
            circulation in the county in which the sale is to be held;

            (l) The Lender Group may credit bid and purchase at any public sale;

            (m) The Lender Group shall have all other rights and remedies
available to it at law or in equity pursuant to any other Loan Documents;

            (n) Any deficiency that exists after disposition of the Collateral
as provided above will be paid immediately by Borrower. Any excess will be
promptly returned, without interest and subject to the rights of third Persons,
by Agent to Borrower; and

            (o) Require Borrower to deliver to Agent promptly upon demand a
complete list of all end-user customers of Borrower with respect to the
Accounts.

9.2   Remedies Cumulative.

            The rights and remedies of the Lender Group under this Agreement,
the other Loan Documents, and all other agreements shall be cumulative. The
Lender Group shall have all other rights and remedies not inconsistent herewith
as provided under the Code, by law, or in equity. No exercise by the Lender
Group of one right or remedy shall be deemed an election, and no waiver by the
Lender Group of any Event of Default shall be deemed a continuing waiver. No
delay by the Lender Group shall constitute a waiver, election, or acquiescence
by it.
   64
10. TAXES AND EXPENSES.

            If Borrower fails to pay any monies (whether taxes, assessments,
insurance premiums, or, in the case of leased properties or assets, rents or
other amounts payable under such leases) due to third Persons, or fails to make
any deposits or furnish any required proof of payment or deposit, all as
required under the terms of this Agreement, then, to the extent that Agent
determines that such failure by Borrower could result in a Material Adverse
Change, in its reasonable discretion and without prior notice to Borrower, Agent
may do any or all of the following: (a) make payment of the same or any part
thereof; (b) set up such reserves in Borrower's Loan Account as Agent reasonably
deems necessary to protect the Lender Group from the exposure created by such
failure; or (c) obtain and maintain insurance policies of the type described in
Section 6.10, and take any action with respect to such policies as Agent deems
prudent. Any such amounts paid by Agent shall constitute Lender Group Expenses.
Any such payments made by Agent shall not constitute an agreement by the Lender
Group to make similar payments in the future or a waiver by the Lender Group of
any Event of Default under this Agreement. Agent need not inquire as to, or
contest the validity of, any such expense, tax, or Lien and the receipt of the
usual official notice for the payment thereof shall be conclusive evidence that
the same was validly due and owing.

11. WAIVERS; INDEMNIFICATION.

11.1  Demand; Protest; etc.

            To the extent permitted by law and not otherwise required under this
Agreement or any other Loan Document, Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment,
nonpayment at maturity, release, compromise, settlement, extension, or renewal
of accounts, documents, instruments, chattel paper, and guarantees at any time
held by the Lender Group on which Borrower may in any way be liable.

11.2  The Lender Group's Liability for Collateral.

            Borrower hereby agrees that: (a) so long as the Lender Group
complies with its obligations, if any, under Section 9-207 of the Code, the
Lender Group shall not in any way or manner be liable or responsible for: (i)
the safekeeping of the Collateral; (ii) any loss or damage thereto occurring or
arising in any manner or fashion from any cause; (iii) any diminution in the
value thereof; or (iv) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other Person; and (b) all risk of loss, damage, or
destruction of the Collateral shall be borne by Borrower.

11.3  Indemnification.

            Borrower shall pay, indemnify, defend, and hold the Agent-Related
Persons, the S&A Agent-Related Persons, the Lender-Related Persons with respect
to each Lender, each Participant, and each of their respective officers,
directors, employees, counsel, agents, and attorneys-in-fact (each, an
"Indemnified Person") harmless (to the fullest extent permitted
   65
by law) from and against any and all claims, demands, suits, actions,
investigations, proceedings, and damages, and all reasonable attorneys fees and
disbursements and other costs and expenses actually incurred in connection
therewith (as and when they are incurred and irrespective of whether suit is
brought), at any time asserted against, imposed upon, or incurred by any of them
in connection with or as a result of or related to the execution, delivery,
enforcement, performance, and administration of this Agreement and any other
Loan Documents or the transactions contemplated herein, and with respect to any
investigation, litigation, or proceeding related to this Agreement, any other
Loan Document, or the use of the proceeds of the credit provided hereunder
(irrespective of whether any Indemnified Person is a party thereto), or any act,
omission, event or circumstance in any manner related thereto (all the
foregoing, collectively, the "Indemnified Liabilities"). Borrower shall have no
obligation to any Indemnified Person under this Section 11.3 with respect to any
Indemnified Liability that a court of competent jurisdiction finally determines
to have resulted from the gross negligence or willful misconduct of such
Indemnified Person. This provision shall survive the termination of this
Agreement and the repayment of the Obligations. If any Indemnified Person makes
any payment to any other Indemnified Person with respect an Indemnified
Liability for which Borrower was required to indemnify the Indemnified Person
receiving such payment, the Indemnified Person making such payment is entitled
to be indemnified and reimbursed by Borrower with respect thereto.

12. NOTICES.

            Unless otherwise provided in this Agreement, all notices or demands
by any party relating to this Agreement or any other Loan Document shall be in

which may be sent by first-class mail, postage prepaid) shall be personally
delivered or sent by registered or certified mail (postage prepaid, return
receipt requested), overnight courier, or telefacsimile to the relevant party,

13. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER.

            THE VALIDITY OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (UNLESS
EXPRESSLY PROVIDED TO THE CONTRARY IN ANOTHER LOAN DOCUMENT IN RESPECT OF SUCH
OTHER LOAN DOCUMENT), THE CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF
AND THEREOF, AND THE RIGHTS OF THE PARTIES HERETO AND THERETO WITH RESPECT TO
ALL MATTERS ARISING HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL
BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK.

            THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS
   67
ARISING IN CONNECTION WITH THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE
TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY
OF NEW YORK, STATE OF NEW YORK, PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE
REQUIRED LENDERS' OPTION, IN THE COURTS OF ANY JURISDICTION WHERE THE REQUIRED
LENDERS ELECT TO BRING SUCH ACTION OR WHERE SUCH COLLATERAL OR OTHER PROPERTY
MAY BE FOUND. BORROWER AND THE LENDER GROUP WAIVE, TO THE EXTENT PERMITTED UNDER
APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON
CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN
ACCORDANCE WITH THIS SECTION 13.

            BORROWER AND THE LENDER GROUP HEREBY WAIVE THEIR RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY

14. DESTRUCTION OF BORROWER'S DOCUMENTS.

            All documents, schedules, invoices, agings, or other papers
delivered to any one or more members of the Lender Group may be destroyed or
otherwise disposed of by such member of the Lender Group 4 months after they are
delivered to or received by such member of the Lender Group, unless Borrower
requests, in writing, the return of said documents, schedules, or other papers
and makes arrangements, at Borrower's expense, for their return.

15. ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS.

15.1  Assignments and Participations.


            (a) Any Lender may assign and delegate to one or more Eligible
Transferees (or any other assignee, if such assignment is in connection with a
merger, consolidation, sale, transfer, or other disposition of all or any
substantial portion of the business or loan portfolio of such Lender) (each an
"Assignee") all, or any ratable part of all, of the Obligations, the Commitments
and the other rights and obligations of such Lender hereunder and under the
other Loan Documents, in a minimum amount of $5,000,000; provided, however, that
Borrower, Agent, and S&A Agent may continue to deal solely and
   68
directly with such Lender in connection with the interest so assigned to an
Assignee until (i) written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee,
shall have been given to Borrower and Agent by such Lender and the Assignee;
(ii) such Assignee shall have delivered to Agent and Borrower such forms, if
any, that such Assignee is required to deliver pursuant to Section 17.10, and
(iii) such Lender and its Assignee shall have delivered to Borrower and Agent an
Assignment and Acceptance ("Assignment and Acceptance") in form and substance
satisfactory to Agent.

            (b) From and after the date that Agent notifies the assignor Lender
that it has received an executed Assignment and Acceptance, (i) the Assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, shall have the rights and obligations of a Lender under the Loan
Documents, and (ii) the assignor Lender shall, to the extent that rights and
obligations hereunder and under the other Loan Documents have been assigned by
it pursuant to such Assignment and Acceptance, relinquish its rights (except
with respect to Section 11.3 hereof) and be released from its obligations to
make Advances under this Agreement (and in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement and the other Loan Documents, such Lender
shall cease to be a party hereto and thereto), and such assignment shall effect
a novation between Borrower and the Assignee.

            (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (1) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other Loan Document furnished
pursuant hereto; (2) such assigning Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of
Borrower or the performance or observance by Borrower of any of its obligations
under this Agreement or any other Loan Document furnished pursuant hereto; (3)
such Assignee confirms that it has received a copy of this Agreement, together
with such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into such Assignment and
Acceptance; (4) such Assignee will, independently and without reliance upon
Agent, S&A Agent, such assigning Lender or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement; (5) such Assignee appoints and authorizes Agent and S&A Agent to take
such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to Agent or S&A Agent, as applicable, by the terms
hereof, together with such powers as are reasonably incidental thereto; (6) such
Assignee has complied, to the extent applicable, with Section 17.10; and (7)
such Assignee agrees that it will perform in accordance with their terms all of
the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.
   69
            (d) Immediately upon receipt and acknowledgment by Agent of a fully
executed Assignment and Acceptance, this Agreement shall be deemed to be amended
to the extent, but only to the extent, necessary to reflect the addition of the
Assignee and the resulting adjustment of the Commitments arising therefrom. The
Commitment allocated to each Assignee shall reduce such Commitments of the
assigning Lender pro tanto.

            (e) Any Lender may at any time, with the written consent of S&A
Agent, sell to one or more commercial banks, financial institutions, or other
Persons (a "Participant") participating interests in the Obligations, the
Commitment, and the other rights and interests of that Lender (the "originating
Lender") hereunder and under the other Loan Documents (provided that no written
consent of S&A Agent shall be required in connection with any sale of any such
participating interests by a Lender to an Eligible Transferee); provided,
however, that (i) the originating Lender's obligations under this Agreement
shall remain unchanged, (ii) the originating Lender shall remain solely
responsible for the performance of such obligations, (iii) Borrower, Agent, and
S&A Agent shall continue to deal solely and directly with the originating Lender
in connection with the originating Lender's rights and obligations under this
Agreement and the other Loan Documents, (iv) no Lender shall transfer or grant
any participating interest under which the Participant has the right to approve
any amendment to, or any consent or waiver with respect to, this Agreement or
any other Loan Document, except to the extent such amendment to, or consent or
waiver with respect to this Agreement or of any other Loan Document would (A)
extend the final maturity date of the Obligations hereunder in which such
Participant is participating; (B) reduce the interest rate applicable to the
Obligations hereunder in which such Participant is participating; (C) release
all or a material portion of the Collateral or guaranties (except to the extent
expressly provided herein or in any of the Loan Documents) supporting the
Obligations hereunder in which such Participant is participating; (D) postpone
the payment of, or reduce the amount of, the interest or fees payable to such
Participant through such Lender; or (E) change the amount or due dates of
scheduled principal repayments or prepayments or premiums; (v) such Participant
shall agree to be bound by the confidentiality provisions of Section 17.16(d) as
if such Participant were a party hereto; (vi) no participating interest shall be
sold to any Person if S&A Agent or the originating Lender knows or reasonably
should know that such Person's primary line of business directly competes with
the business of Borrower, (vii) at Borrower's request, each Participant shall
certify that the primary line of business of such Participant does not directly
compete with the business of Borrower, and (viii) all amounts payable by
Borrower hereunder shall be determined as if such Lender had not sold such
participation; except that, if amounts outstanding under this Agreement are due
and unpaid, or shall have been declared or shall have become due and payable
upon the occurrence of an Event of Default, each Participant shall be deemed to
have the right of set-off in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement. The rights of any Participant only shall be derivative through the
originating Lender with whom such Participant participates and no Participant
shall have any direct rights as to the other Lenders, Agent, S&A Agent,
Borrower, the Collections, the Collateral, or otherwise in respect of the
Obligations. No Participant shall have the right to
   70
participate directly in the making of decisions by the Lenders among
themselves.

            (f) In connection with any such assignment or participation or
proposed assignment or participation, a Lender may disclose all documents and
information which it now or hereafter may have relating to Borrower or
Borrower's business.

            (g) Any other provision in this Agreement notwithstanding, any
Lender may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement in favor of any
Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Bank
or U.S. Treasury Regulation 31 CFR Section 203.14, and such Federal Reserve Bank
may enforce such pledge or security interest in any manner permitted under
applicable law.

15.2  Successors.

            This Agreement shall bind and inure to the benefit of the respective
successors and assigns of each of the parties; provided, however, that Borrower
may not assign this Agreement or any rights or duties hereunder without the
Lenders' prior written consent and any prohibited assignment shall be absolutely
void ab initio. No consent to assignment by the Lenders shall release Borrower
from its Obligations. A Lender may assign this Agreement and the other Loan
Documents and its rights and duties hereunder and thereunder pursuant to Section
15.1 hereof and, except as expressly required pursuant to Section 15.1 hereof,
no consent or approval by Borrower is required in connection with any such
assignment.

16. AMENDMENTS; WAIVERS.

16.1 Amendments and Waivers.

            No amendment or waiver of any provision of this Agreement or any
other Loan Document, and no consent with respect to any departure by Borrower
therefrom, shall be effective unless the same shall be in writing and signed by
the Required Lenders (or by Agent at the written request of the Required
Lenders) and Borrower and then any such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given;
provided, however, that no such waiver, amendment, or consent shall, unless in
writing and signed by all the Lenders and Borrower and acknowledged by Agent, do
any of the following:

            (a) increase or extend the Commitment of any Lender;

            (b) postpone or delay any date fixed by this Agreement or any other
Loan Document for any payment of principal, interest, fees or other amounts due
to the Lenders (or any of them) hereunder or under any other Loan Document;

            (c) reduce the principal of, or the rate of interest specified
herein on any Loan, or any fees or other amounts payable hereunder or under any
other Loan Document;
   71
            (d) change the percentage of the Commitments that is required for
the Lenders or any of them to take any action hereunder;

            (e) amend this Section or any provision of the Agreement providing
for consent or other action by all Lenders;

            (f) release the Agent's Lien for the benefit of the Lender Group on
any Collateral other than as permitted by Section 17.11;

            (g) change the definition of "Required Lenders";

            (h) release Borrower from any Obligation for the payment of money;

            (i) amend Section 2.4(b);

            (j) amend any of the provisions of Section 17;

            (k) change the definition of Eligible Accounts; or

            (l) change the advance rate against Eligible Accounts or otherwise
amend Section 2.1;

and, provided further, however, that no amendment, waiver or consent shall,
unless in writing and signed by Agent, affect the rights or duties of Agent
under this Agreement or any other Loan Document; and provided further, however,
that no amendment, waiver or consent shall, unless in writing and signed by S&A
Agent, affect the specific rights or duties of S&A Agent under this Agreement or
any other Loan Document. The foregoing notwithstanding, any amendment,
modification, waiver, consent, termination, or release of or with respect to any
provision of this Agreement or any other Loan Document that relates only to the
relationship of the Lender Group among themselves, and that does not affect the
rights or obligations of Borrower, shall not require consent by or the agreement
of Borrower.

16.2  No Waivers; Cumulative Remedies.

            No failure by Agent or any Lender to exercise any right, remedy, or
option under this Agreement, any other Loan Document, or any present or future
supplement hereto or thereto, or in any other agreement between or among
Borrower and Agent or any Lender, or delay by Agent or any Lender in exercising
the same, will operate as a waiver thereof. No waiver by Agent or any Lender
will be effective unless it is in writing, and then only to the extent
specifically stated. No waiver by Agent or the Lenders on any occasion shall
affect or diminish Agent's and each Lender's rights thereafter to require strict
performance by Borrower of any provision of this Agreement. Agent's and each
Lender's rights under this Agreement and the other Loan Documents will be
cumulative and not exclusive of any other right or remedy which Agent or any
Lender may have.
   72
17. AGENT; THE LENDER GROUP.

17.1 Appointment and Authorization of Agent.

            Each Lender hereby designates and appoints FNB and GSCP as its
agents under this Agreement and the other Loan Documents and each Lender hereby
irrevocably authorizes Agent and S&A Agent to take such action on its behalf
under the provisions of this Agreement and each other Loan Document and to
exercise such powers and perform such duties as are expressly delegated to Agent
or S&A Agent, as applicable, it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto. Agent
and S&A Agent each agrees to act as such on the express conditions contained in
this Section 17. The provisions of this Section 17 are solely for the benefit of
Agent, S&A Agent, and the Lenders, and Borrower shall have no rights as a third
party beneficiary of any of the provisions contained herein; provided, however,
that certain of the provisions of Section 17.10 hereof also shall be for the
benefit of Borrower. Any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document notwithstanding, neither Agent nor S&A
Agent shall have any duties or responsibilities, except those expressly set
forth herein, nor shall Agent nor S&A Agent have or be deemed to have any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against Agent or S&A
Agent; it being expressly understood and agreed that the use of the words
"Agent" and "S&A Agent" is for convenience only, that FNB and GSCP are merely
the representative of the Lenders, and have only the contractual duties set
forth herein. Except as expressly otherwise provided in this Agreement, Agent
and S&A Agent shall have and may use their sole discretion with respect to
exercising or refraining from exercising any discretionary rights or taking or
refraining from taking any actions which Agent or S&A Agent, as applicable, is
expressly entitled to take or assert under or pursuant to this Agreement and the
other Loan Documents. Without limiting the generality of the foregoing, or of
any other provision of the Loan Documents that provides rights or powers to
Agent, Lenders agree that Agent shall have the right to exercise the following
powers as long as this Agreement remains in effect: (a) maintain, in accordance
with its customary business practices, ledgers and records reflecting the status
of the Advances, the Collateral, the Collections, and related matters; (b)
execute or file any and all financing or similar statements or notices,
amendments, renewals, supplements, documents, instruments, proofs of claim,
notices and other written agreements with respect to the Loan Documents; (c)
make Advances, for itself or on behalf of Lenders as provided in the Loan
Documents; (d) exclusively receive, apply, and distribute the Collections as
provided in the Loan Documents; (e) open and maintain such bank accounts and
lock boxes as Agent reasonably deems necessary and appropriate in accordance
with the Loan Documents for the foregoing purposes with respect to the
Collateral and the Collections; (f) perform, exercise, and enforce any and all
other rights and remedies of the Lender Group with respect to Borrower, the
Obligations, the Collateral, the Collections, or otherwise related to any of
same as provided in the Loan Documents; and (g) incur and pay such Lender Group
Expenses as Agent may reasonably deem necessary or appropriate for the
performance and fulfillment of its functions and powers pursuant to the Loan
Documents.
   73
17.2  Delegation of Duties.

            Except as otherwise provided in this section, Agent and S&A Agent
may execute any of their respective duties under this Agreement or any other
Loan Document by or through agents, employees or attorneys-in-fact and shall be
entitled to advice of counsel concerning all matters pertaining to such duties.
Neither Agent nor S&A Agent shall be responsible for the negligence or
misconduct of any agent or attorney-in-fact that it selects as long as such
selection was made in compliance with this section and without gross negligence
or willful misconduct.


17.3  Liability of Agent and S&A Agent.

            None of the Agent-Related Persons, nor the S&A Agent-Related Persons
shall (i) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by Borrower or any
Subsidiary or Affiliate of Borrower, or any officer or director thereof,
contained in this Agreement or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by Agent or S&A Agent, as applicable, under or in connection with,
this Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of Borrower or any other party to any Loan Document
to perform its obligations hereunder or thereunder. No Agent-Related Person, nor
any S&A Agent-Related Person shall be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of Borrower or any of
Borrower's Subsidiaries or Affiliates.

17.4  Reliance by Agent and S&A Agent.

            Agent and S&A Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation reasonably believed by it to be
genuine and correct and to have been signed, sent, or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to Borrower or counsel to any Lender), independent accountants and other experts
selected by Agent or S&A Agent, as applicable. Agent and S&A Agent shall be
fully justified in failing or refusing to take any action under this Agreement
or any other Loan Document unless Agent or S&A Agent, as applicable, shall first
receive such advice or concurrence of the Lenders as it deems appropriate and
until such instructions are received, Agent and S&A Agent shall act, or refrain
from acting, as they deem advisable. If Agent or S&A Agent so requests, Agent or
S&A Agent, as applicable, shall first be indemnified to its reasonable
satisfaction by Lenders against any and all liability and expense that may be
incurred by it by reason of taking or continuing to take any such action. Agent
and S&A Agent shall in
   74
all cases be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance with a request or consent of
the requisite Lenders and such request and any action taken or failure to act
pursuant thereto shall be binding upon all of the Lenders. If in the reasonable
opinion of Agent the distribution of any amount received by it in such capacity
hereunder or under any of the other Loan Documents reasonably could be expected
to result in it suffering a liability, Agent may refrain from making
distribution until its right to make distribution shall have been adjudicated by
a court of competent jurisdiction. If a court of competent jurisdiction shall
adjudge that any amount received and distributed by Agent is to be repaid, each
Person to whom any such distribution shall have been made shall either repay to
the Agent its proportionate share of the amount so adjudged or shall pay over
the same in such manner to such Persons as shall be determined by such court.

17.5  Notice of Default or Event of Default.

            Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default, except with respect to defaults
in the payment of principal, interest, fees, and expenses required to be paid to
Agent for the account of the Lenders, except with respect to Events of Default
of which Agent has actual knowledge, unless Agent shall have received written
notice from a Lender or Borrower referring to this Agreement, describing such
Default or Event of Default, and stating that such notice is a "notice of
default." Agent promptly will notify the Lenders of its receipt of any such
notice or of any Event of Default of which Agent has actual knowledge. If any
Lender obtains actual knowledge of any Event of Default, such Lender promptly
shall notify the other Lenders and Agent of such Event of Default. Each Lender
shall be solely responsible for giving any notices to its Participants, if any.
Subject to Section 17.4, Agent shall take such action with respect to such
Default or Event of Default as may be requested by the Required Lenders in
accordance with Section 9; provided, however, that unless and until Agent has
received any such request, Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable.

17.6  Credit Decision.

            Each Lender acknowledges that none of the Agent-Related Persons nor
any of the S&A Agent-Related Persons has made any representation or warranty to
it, and that no act by Agent or S&A Agent hereinafter taken, including any
review of the affairs of Borrower and its Subsidiaries or Affiliates, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
or S&A Agent-Related Person to any Lender. Each Lender represents to Agent and
to S&A Agent that it has, independently and without reliance upon any
Agent-Related Person or any S&A Agent-Related Person and based on such documents
and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of Borrower and any other Person (other
than the Lender Group) party to a Loan Document, and all applicable bank
regulatory laws relating to the transactions
   75
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to Borrower. Each Lender also represents that it will,
independently and without reliance upon any Agent-Related Person or any S&A
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of Borrower and any other Person (other
than the Lender Group) party to a Loan Document. Except for notices, reports and
other documents expressly herein required to be furnished to the Lenders by
Agent or S&A Agent, neither Agent nor S&A Agent, as applicable, shall have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of Borrower and any other Person party
to a Loan Document that may come into the possession of any of the Agent-Related
Persons or the S&A Agent-Related Persons.

17.7  Costs and Expenses; Indemnification.

            Agent and S&A Agent may incur and pay Lender Group Expenses to the
extent Agent or S&A Agent, as applicable reasonably deems necessary or
appropriate for the performance and fulfillment of their respective functions,
powers, and obligations pursuant to the Loan Documents, including without
limiting the generality of the foregoing, court costs, reasonable attorneys fees
and expenses, costs of collection by outside collection agencies and auctioneer
fees and costs of security guards or insurance premiums paid to maintain the
Collateral, whether or not Borrower is obligated to reimburse Agent, S&A Agent,
or Lenders for such expenses pursuant to the Loan Agreement or otherwise. Agent
is authorized and directed to deduct and retain sufficient amounts from
Collections to reimburse Agent and S&A Agent, as applicable, for such
out-of-pocket costs and expenses prior to the distribution of any amounts to
Lenders. In the event Agent or S&A Agent is not reimbursed for such costs and
expenses from Collections, each Lender hereby agrees that it is and shall be
obligated to pay to or reimburse Agent or S&A Agent for the amount of such
Lender's Pro Rata Share thereof. Whether or not the transactions contemplated
hereby are consummated, the Lenders shall indemnify upon demand the
Agent-Related Persons and the S&A Agent-Related Persons (in each case, to the
extent not reimbursed by or on behalf of Borrower and without limiting the
obligation of Borrower to do so), according to their Pro Rata Shares, from and
against any and all Indemnified Liabilities; provided, however, that no Lender
shall be liable for the payment to the Agent-Related Persons or the S&A
Agent-Related Persons of any portion of such Indemnified Liabilities resulting
solely from such Person's gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender shall reimburse Agent and S&A Agent
upon demand for such Lender's ratable share of any costs or out-of-pocket
expenses (including attorneys fees and expenses) incurred by Agent or S&A Agent,
as applicable, in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the
   76
extent that Agent or S&A Agent, as applicable, is not reimbursed for such
expenses by or on behalf of Borrower. The undertaking in this section shall
survive the payment of all Obligations hereunder and the resignation or
replacement of Agent or S&A Agent, as applicable.

17.8  Agent and S&A Agent in Individual Capacity.

            FNB, GSCP, and their respective Affiliates may make loans to, issue
letters of credit for the account of, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with Borrower and its Subsidiaries and
Affiliates and any other Person (other than the Lender Group) party to any Loan
Documents as though FNB were not Agent hereunder, and GSCP were not S&A Agent
hereunder, and, in each case, without notice to or consent of the Lenders. The
Lenders acknowledge that, pursuant to such activities, FNB, GSCP, or their
respective Affiliates may receive information regarding Borrower or its
Affiliates and any other Person (other than the Lender Group) party to any Loan
Documents that is subject to confidentiality obligations in favor of Borrower or
such other Person and that prohibit the disclosure of such information to the
Lenders, and the Lenders acknowledge that, in such circumstances (and in the
absence of a waiver of such confidentiality obligations, which waiver Agent or
S&A Agent, as applicable, will use its reasonable best efforts to obtain),
neither Agent nor S&A Agent shall be under an obligation to provide such
information to them. The terms "Lender" and "Lenders" include FNB in its
individual capacity and GSCP in its individual capacity.

17.9  Successor Agent and S&A Agent.

            (a) Agent may resign as Agent upon 45 days notice to the Lenders;
provided, however, that such 45 day notice shall not be required if GSCP
exercises its Purchase Option (as defined in the Agents' Side Letter). If Agent
resigns under this Agreement, the Required Lenders shall appoint a successor
Agent for the Lenders. If no successor Agent is appointed prior to the effective
date of the resignation of Agent, Agent may appoint, after consulting with the
Lenders, a successor Agent. If Agent has materially breached or failed to
perform any material provision of this Agreement or of applicable law, the
Required Lenders may agree in writing to remove and replace Agent with a
successor Agent from among the Lenders. In any such event, upon the acceptance
of its appointment as successor Agent hereunder, such successor Agent shall
succeed to all the rights, powers and duties of the retiring Agent and the term
"Agent" shall mean such successor Agent and the retiring Agent's appointment,
powers and duties as Agent shall be terminated. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Section 17 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement. If no successor Agent has accepted appointment as
Agent by the date which is 45 days following a retiring Agent's notice of
resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective and the Lenders shall perform all of the duties of Agent
hereunder until such time, if any, as the Lenders appoint a successor Agent as
provided for above.
   77
            (b) S&A Agent may resign as S&A Agent upon 45 days notice to the
Lenders. If S&A Agent resigns under this Agreement, the Required Lenders shall
appoint a successor S&A Agent for the Lenders. If no successor S&A Agent is
appointed prior to the effective date of the resignation of S&A Agent, S&A Agent
may appoint, after consulting with the Lenders, a successor S&A Agent. If S&A
Agent has materially breached or failed to perform any material provision of
this Agreement or of applicable law, the Required Lenders may agree in writing
to remove and replace S&A Agent with a successor S&A Agent from among the
Lenders. In any such event, upon the acceptance of its appointment as successor
S&A Agent hereunder, such successor S&A Agent shall succeed to all the rights,
powers and duties of the retiring S&A Agent and the term "S&A Agent" shall mean
such successor S&A Agent and the retiring S&A Agent's appointment, powers and
duties as S&A Agent shall be terminated. After any retiring S&A Agent's
resignation hereunder as S&A Agent, the provisions of this Section 17 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was S&A Agent under this Agreement. If no successor S&A Agent has accepted
appointment as S&A Agent by the date which is 45 days following a retiring S&A
Agent's notice of resignation, the retiring S&A Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of S&A Agent hereunder until such time, if any, as the Lenders appoint a
successor S&A Agent as provided for above.

17.10 Withholding Tax.

            (a) If any Lender is a "foreign corporation, partnership or trust"
within the meaning of the IRC and such Lender claims exemption from, or a
reduction of, U.S. withholding tax under Sections 1441 or 1442 of the IRC, such
Lender agrees with and in favor of Agent and Borrower, to deliver to Agent and
Borrower:

                 (i) if such Lender claims an exemption from, or a reduction of,
            withholding tax under a United States tax treaty, properly completed
            IRS Forms 1001 and W-8 before the payment of any interest in the
            first calendar year and before the payment of any interest in each
            third succeeding calendar year during which interest may be paid
            under this Agreement;

                 (ii) if such Lender claims that interest paid under this
            Agreement is exempt from United States withholding tax because it is
            effectively connected with a United States trade or business of such
            Lender, two properly completed and executed copies of IRS Form 4224
            before the payment of any interest is due in the first taxable year
            of such Lender and in each succeeding taxable year of such Lender
            during which interest may be paid under this Agreement, and IRS Form
            W-9; and

                 (iii) such other form or forms as may be required under the IRC
            or other laws of the United States as a condition to exemption from,
            or reduction of, United States withholding tax.
   78
Such Lender agrees promptly to notify Agent and Borrower of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

            (b) If any Lender claims exemption from, or reduction of,
withholding tax under a United States tax treaty by providing IRS Form 1001 and
such Lender sells, assigns, grants a participation in, or otherwise transfers
all or part of the Obligations of Borrower to such Lender, such Lender agrees to
notify Agent of the percentage amount in which it is no longer the beneficial
owner of Obligations of Borrower to such Lender. To the extent of such
percentage amount, Agent will treat such Lender's IRS Form 1001 as no longer
valid.

            (c) If any Lender claiming exemption from United States withholding
tax by filing IRS Form 4224 with Agent sells, assigns, grants a participation
in, or otherwise transfers all or part of the Obligations of Borrower to such
Lender, such Lender agrees to undertake sole responsibility for complying with
the withholding tax requirements imposed by Sections 1441 and 1442 of the IRC.

            (d) If any Lender is entitled to a reduction in the applicable
withholding tax, Agent may withhold from any interest payment to such Lender an
amount equivalent to the applicable withholding tax after taking into account
such reduction. If the forms or other documentation required by subsection (a)
of this Section are not delivered to Agent, then Agent may withhold from any
interest payment to such Lender not providing such forms or other documentation
an amount equivalent to the applicable withholding tax.

            (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that Agent did not properly
withhold tax from amounts paid to or for the account of any Lender (because the
appropriate form was not delivered, was not properly executed, or because such
Lender failed to notify Agent or Borrower of a change in circumstances which
rendered the exemption from, or reduction of, withholding tax ineffective, or
for any other reason) such Lender shall indemnify Agent fully for all amounts
paid, directly or indirectly, by Agent or Borrower as tax or otherwise,
including penalties and interest, and including any taxes imposed by any
jurisdiction on the amounts payable to Agent or Borrower, as applicable, under
this section, together with all costs and expenses (including attorneys fees and
expenses). The obligation of the Lenders under this subsection shall survive the
payment of all Obligations and the resignation or replacement of Agent.

17.11 Collateral Matters.

            (a) The Lenders hereby irrevocably authorize Agent, at its option
and in its sole discretion, to release any Lien on any Collateral (i) upon the
termination of the Commitments and payment and satisfaction in full by Borrower
of all Obligations; (ii) constituting property being sold or disposed of if a
release is required or desirable in connection therewith and if Borrower
certifies to Agent that the sale or disposition is permitted under Section 7 of
this Agreement or the other Loan Documents (and Agent may rely conclusively on
any such certificate, without further inquiry); (iii) constituting property
   79
in which Borrower owned no interest at the time the security interest was
granted or at any time thereafter; or (iv) constituting property leased to
Borrower under a lease that has expired or is terminated in a transaction
permitted under this Agreement. Except as provided above, Agent will not execute
and deliver a release of any Lien on any Collateral without the prior written
authorization of (y) if the release is of all or substantially all of the
Collateral, all of the Lenders, or (z) otherwise, the Required Lenders. Upon
request by Agent or Borrower at any time, the Lenders will confirm in writing
Agent's authority to release any such Liens on particular types or items of
Collateral pursuant to this Section 17.11; provided, however, that (1) Agent
shall not be required to execute any document necessary to evidence such release
on terms that, in Agent's opinion, would expose Agent to liability or create any
obligation or entail any consequence other than the release of such Lien without
recourse, representation, or warranty, and (2) such release shall not in any
manner discharge, affect, or impair the Obligations or any Liens (other than
those expressly being released) upon (or obligations of Borrower in respect of)
all interests retained by Borrower, including, the proceeds of any sale, all of
which shall continue to constitute part of the Collateral.

            (b) Agent shall have no obligation whatsoever to any of the Lenders
to assure that the Collateral exists or is owned by Borrower or is cared for,
protected, or insured or has been encumbered, or that the Agent's Liens have
been properly or sufficiently or lawfully created, perfected, protected, or
enforced or are entitled to any particular priority, or to exercise at all or in
any particular manner or under any duty of care, disclosure or fidelity, or to
continue exercising, any of the rights, authorities and powers granted or
available to Agent pursuant to any of the Loan Documents, it being understood
and agreed that in respect of the Collateral, or any act, omission or event
related thereto, subject to the terms and conditions contained herein, Agent may
act in any manner it may deem appropriate, in its sole discretion given Agent's
own interest in the Collateral in its capacity as one of the Lenders and that
Agent shall have no other duty or liability whatsoever to any Lender as to any
of the foregoing, except as otherwise provided herein.

17.12 Restrictions on Actions by Lenders; Sharing of Payments.

            (a) Each Lender agrees that: (i) unless an Event of Default has
occurred and is continuing, such Lender shall not without the express consent of
the Required Lenders (but, if an Event of Default has occurred and is
continuing, then to the extent that it is lawfully entitled to do so, such
Lender may, at its election, and shall, upon the request of the Required
Lenders), set off against the Obligations, any amounts owing by such Lender to
Borrower or any accounts of Borrower now or hereafter maintained with such
Lender; (ii) such Lender shall not, without the express consent of all the
Lenders, set off against any Indebtedness (other than Obligations) of Borrower
owing to such Lender any amounts owing by such Lender to Borrower, including any
amounts evidenced by accounts now or hereafter maintained with such Lender; and
(iii) such Lender shall not, without the express consent of all the Lenders,
take or cause to be taken any action, including, the commencement of any legal
or equitable proceedings, to foreclose any Lien on, or otherwise enforce any
security interest in, any of the Collateral the purpose of which is, or could
be, to give such Lender any preference or priority against the other Lenders
with respect to the Collateral. The foregoing
   80
to the contrary notwithstanding, if any Lender provides Borrower with a letter
of credit and obtains cash collateral to secure Borrower's reimbursement
obligations thereunder, such Lender shall not be restricted by the foregoing
provisions from applying such cash collateral to such reimbursement obligations.

            (b) Subject to Section 17.8, if, at any time or times any Lender
shall receive (i) by payment, foreclosure, setoff or otherwise, any proceeds of
Collateral or any payments with respect to the Obligations arising under, or
relating to, this Agreement or the other Loan Documents, except for any such
proceeds or payments received by such Lender from Agent pursuant to the terms of
this Agreement, or (ii) payments from Agent in excess of such Lender's ratable
portion of all such distributions by Agent, such Lender promptly shall (1) turn
the same over to Agent, in kind, and with such endorsements as may be required
to negotiate the same to Agent, or in same day funds, as applicable, for the
account of all of the Lenders and for application to the Obligations in
accordance with the applicable provisions of this Agreement, or (2) purchase,
without recourse or warranty, an undivided interest and participation in the
Obligations owed to the other Lenders so that such excess payment received shall
be applied ratably as among the Lenders in accordance with their Pro Rata
Shares; provided, however, that if all or part of such excess payment received
by the purchasing party is thereafter recovered from it, those purchases of
participations shall be rescinded in whole or in part, as applicable, and the
applicable portion of the purchase price paid therefor shall be returned to such
purchasing party, but without interest except to the extent that such purchasing
party is required to pay interest in connection with the recovery of the excess
payment.

17.13 Agency for Perfection.

            Agent and each Lender hereby appoints each other Lender as agent for
the purpose of perfecting the Agent's Liens in assets which, in accordance with
Article 9 of the UCC can be perfected only by possession. Should any Lender
obtain possession of any such Collateral, such Lender shall notify Agent
thereof, and, promptly upon Agent's request therefor shall deliver such
Collateral to Agent or in accordance with Agent's instructions.

17.14 Payments by Agent to the Lenders.

            All payments to be made by Agent to the Lenders shall be made by
bank wire transfer or internal transfer of immediately available funds pursuant
to such wire transfer instructions as each party may designate for itself by
written notice to Agent. Concurrently with each such payment, Agent shall
identify whether such payment (or any portion thereof) represents principal,
premium or interest on revolving advances or otherwise.

17.15 Concerning the Collateral and Related Loan Documents.

            Each member of the Lender Group authorizes and directs Agent to
enter into this Agreement and the other Loan Documents relating to the
Collateral, for the benefit of the Lender Group. Each member of the Lender Group
agrees that any action taken by Agent or all Lenders, as applicable, in
accordance with the terms of this Agreement or the other
   81
Loan Documents relating to the Collateral and the exercise by Agent or all
Lenders, as applicable, of their respective powers set forth therein or herein,
together with such other powers that are reasonably incidental thereto, shall be
binding upon all of the Lenders.

17.16 Field Audits and Examination Reports; Confidentiality; Disclaimers by
Lenders; Other Reports and Information.

            By signing this Agreement, each Lender:

            (a) is deemed to have requested that Agent or S&A Agent furnish such
Lender, promptly after it becomes available, a copy of each field audit or
examination report (each a "Report" and collectively, "Reports") prepared by
Agent or S&A Agent, as applicable, and Agent or S&A Agent, shall so furnish each
Lender with such Reports;

            (b) expressly agrees and acknowledges that neither any other Lender,
S&A Agent, nor Agent (i) makes any representation or warranty as to the accuracy
of any Report, or (ii) shall be liable for any information contained in any
Report;

            (c) expressly agrees and acknowledges that the Reports are not
comprehensive audits or examinations, that Agent, S&A Agent, or other party
performing any audit or examination will inspect only specific information
regarding Borrower and will rely significantly upon Borrower's books and
records, as well as on representations of Borrower's personnel;

            (d) agrees to keep all Reports and other material, non-public
information regarding Borrower and its Subsidiaries and their operations,
assets, and existing and contemplated business plans (collectively, the
"Confidential Information") in a confidential manner; it being understood and
agreed by Borrower that in any event such Lender may make disclosures (a) to
counsel for and other advisors, accountants, and auditors to such Lender, (b)
reasonably required by any bona fide potential or actual Assignee, transferee,
or Participant in connection with any contemplated or actual assignment or
transfer by such Lender of an interest herein or any participation interest in
such Lender's rights hereunder, provided that such potential or Actual Assignee,
transferee, or Participant shall have agreed prior to such disclosure to be
bound by the terms of this Section 17.16(d) as if such potential or actual
Assignee, transferee, or Participant were a party hereto, (c) of information
that has become public by disclosures made by Persons other than such Lender,
its Affiliates, assignees, transferees, or participants, or (d) as required or
requested by any court, governmental or administrative agency, pursuant to any
subpoena or other legal process, or by any law, statute, regulation, or court
order; provided, however, that, unless prohibited by applicable law, statute,
regulation, or court order, such Lender shall notify Borrower of any request by
any court, governmental or administrative agency, or pursuant to any subpoena or
other legal process for disclosure of any such non-public material information
concurrent with, or where practicable, prior to the disclosure thereof; and

            (e) without limiting the generality of any other indemnification
provision contained in this Agreement, agrees: (i) to hold Agent, S&A Agent, and
any such other
   82
Lender preparing a Report harmless from any action the indemnifying Lender may
take or conclusion the indemnifying Lender may reach or draw from any Report in
connection with any loans or other credit accommodations that the indemnifying
Lender has made or may make to Borrower, or the indemnifying Lender's
participation in, or the indemnifying Lender's purchase of, a loan or loans of
Borrower; and (ii) to pay and protect, and indemnify, defend and hold Agent, S&A
Agent, and any such other Lender preparing a Report harmless from and against,
the claims, actions, proceedings, damages, costs, expenses and other amounts
(including, attorney costs) incurred by Agent, S&A Agent, and any such other
Lender preparing a Report as the direct or indirect result of any third parties
who might obtain all or part of any Report through the indemnifying Lender.

In addition to the foregoing: (x) Any Lender may from time to time request of
Agent in writing that Agent provide to such Lender a copy of any report or
document provided by Borrower to Agent that has not been contemporaneously
provided by Borrower to such Lender, and, upon receipt of such request, Agent
shall provide a copy of same to such Lender promptly upon receipt thereof from
Borrower; (y) To the extent that Agent is entitled, under any provision of the
Loan Documents, to request additional reports or information from Borrower, any
Lender may, from time to time, reasonably request Agent to exercise such right
as specified in such Lender's notice to Agent, whereupon Agent promptly shall
request of Borrower the additional reports or information specified by such
Lender, and, upon receipt thereof from Borrower, Agent promptly shall provide a
copy of same to such Lender; and (z) Any time that Agent renders to Borrower a
statement regarding the Loan Account, Agent shall send a copy of such statement
to each Lender.

17.17 Several Obligations; No Liability

            Notwithstanding that certain of the Loan Documents now or hereafter
may have been or will be executed only by or in favor of Agent in its capacity
as such, and not by or in favor of the Lenders, any and all obligations on the
part of Agent (if any) to make any credit available hereunder shall constitute
the several (and not joint) obligations of the respective Lenders on a ratable
basis, according to their respective Commitments, to make an amount of such
credit not to exceed, in principal amount, at any one time outstanding, the
amount of their respective Commitments. Nothing contained herein shall confer
upon any Lender any interest in, or subject any Lender to any liability for, or
in respect of, the business, assets, profits, losses, or liabilities of any
other Lender. Each Lender shall be solely responsible for notifying its
Participants of any matters relating to the Loan Documents to the extent any
such notice may be required, and no Lender shall have any obligation, duty, or
liability to any Participant of any other Lender. Except as provided in Section
17.7, no member of the Lender Group shall have any liability for the acts or any
other member of the Lender Group. No Lender shall be responsible to Borrower or
any other Person for any failure by any other Lender to fulfill its obligations
to make credit available hereunder, nor to advance for it or on its behalf in
connection with its Commitment, nor to take any other action on its behalf
hereunder or in connection with the financing contemplated herein.

17.18 Legal Representation of GSCP.
   83
            In connection with the negotiation, drafting, and execution of this
Agreement and the other Loan Documents, or in connection with future legal
representation relating to loan administration, amendments, modifications,
waivers, or enforcement of remedies, Brobeck, Phleger & Harrison LLP ("Brobeck")
only has represented and only shall represent GSCP in its capacity as S&A Agent
and as a Lender. Each other Lender and Agent hereby acknowledges that Brobeck
does not represent any other Lender or Agent in connection with any such
matters.

18. GENERAL PROVISIONS.

by Borrower and each member of the Lender Group whose signature is provided for
on the signature pages hereof.

18.2  Section Headings.

            Headings and numbers have been set forth herein for convenience
only. Unless the contrary is compelled by the context, everything contained in
each section applies equally to this entire Agreement.

18.3  Interpretation.

            Neither this Agreement nor any uncertainty or ambiguity herein shall
be construed or resolved against the Lender Group or Borrower, whether under any
rule of construction or otherwise. On the contrary, this Agreement has been
reviewed by all parties and shall be construed and interpreted according to the
ordinary meaning of the words used so as to fairly accomplish the purposes and
intentions of all parties hereto.

18.4  Severability of Provisions.

            Each provision of this Agreement shall be severable from every other

   84
18.6  Counterparts; Telefacsimile Execution.

            This Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken
together, shall constitute but one and the same Agreement. Delivery of an
executed counterpart of this Agreement by telefacsimile shall be equally as
effective as delivery of an original executed counterpart of this Agreement. Any
party delivering an executed counterpart of this Agreement by telefacsimile also
shall deliver an original executed counterpart of this Agreement but the failure
to deliver an original executed counterpart shall not affect the validity,
enforceability, and binding effect of this Agreement. The foregoing shall apply
to each other Loan Document mutatis mutandis.

18.7  Revival and Reinstatement of Obligations.

            If the incurrence or payment of the Obligations by Borrower or any
guarantor of the Obligations or the transfer by either or both of such parties
to the Lender Group of any property of either or both of such parties should for
any reason subsequently be declared to be void or voidable under any state or
federal law relating to creditors' rights, including provisions of the
Bankruptcy Code relating to fraudulent conveyances, preferences, and other
voidable or recoverable payments of money or transfers of property
(collectively, a "Voidable Transfer"), and if the Lender Group is required to
repay or restore, in whole or in part, any such Voidable Transfer, or elects to
do so upon the reasonable advice of its counsel, then, as to any such Voidable
Transfer, or the amount thereof that the Lender Group is required or elects to
repay or restore, and as to all reasonable costs, expenses, and attorneys fees
of the Lender Group related thereto, the liability of Borrower or such guarantor
automatically shall be revived, reinstated, and restored and shall exist as
though such Voidable Transfer had never been made.

18.8  Integration.

            This Agreement, together with the other Loan Documents, reflects the
entire understanding of the parties with respect to the transactions
contemplated hereby and shall not be contradicted or qualified by any other
agreement, oral or written, before the date hereof.

18.9  GSCP as S&A Agent.

            GSCP, as Syndication & Arrangement Agent, has performed, and will
continue to perform, important functions with respect to the credit facilities
provided for in the Loan Documents. In recognition of its role, GSCP is
designated Syndication & Arrangement Agent and may so identify itself in public
communications with respect to this credit. The foregoing notwithstanding, GSCP
shall have no duties, responsibilities, obligations, or liabilities except the
right to consent to Eligible Transferees and such, if any, other duties,
responsibilities, obligations, or liabilities as may be set forth expressly in
any Loan Document.
