         Subject to the terms and conditions set forth herein, each Lender
severally agrees to make Loans to the Borrower in Dollars, at any time and from
time to time, during the period from the Effective Date to the Maturity Date
(each a "Loan" and collectively the "Loans"); provided, however, that (i) the

and (ii) with respect to each individual Lender, the Lender's Commitment
Percentage multiplied by the outstanding Loans shall not exceed such Lender's
Commitment. Subject to the terms of this Credit Agreement, the Borrower may
borrow, repay and reborrow Loans.

         2.2 METHOD OF BORROWING FOR LOANS.

         By no later than 11:00 a.m. (a) on the date of the requested borrowing
of Loans that will be Base Rate Loans or (b) three Business Days prior to the
date of the requested borrowing of Loans that will be Eurodollar Loans, the
Borrower shall telephone the Administrative Agent as well as submit a written
Notice of Borrowing in the form of Exhibit 2.2 to the Administrative Agent
setting forth (i) the amount requested, (ii) whether such Loans shall accrue
interest at the Base Rate or the Adjusted Eurodollar Rate, (iii) with respect to
Loans that will be Eurodollar Loans, the Interest Period applicable thereto and

its Commitment Percentage of the requested Loans available to the Administrative
Agent by 1:00 p.m. on the date specified in the Notice of Borrowing by deposit,
in Dollars, of immediately available funds at the Agency

                                       13

to the Borrower by the Administrative Agent by crediting the account of the
Borrower on the books of such office of the Administrative Agent, to the extent
the amount of such Loans are made available to the Administrative Agent.

Lender in its obligation to make Loans hereunder; provided, however, that the
failure of any Lender to fulfill its obligations hereunder shall not relieve any
other Lender of its obligations hereunder. Unless the Administrative Agent shall
have been notified by any Lender prior to 1:00 p.m. on the date specified in the
Notice of Borrowing that such Lender does not intend to make available to the
Administrative Agent its portion of the Loans to be made on such date, the
Administrative Agent may assume that such Lender has made such amount available
to the Administrative Agent on the date of such Loans, and the Administrative
Agent in reliance upon such assumption, may (in its sole discretion but without
any obligation to do so) make available to the Borrower a corresponding amount.
If such corresponding amount is not in fact made available to the Administrative
Agent, the Administrative Agent shall be able to recover such corresponding
amount from such Lender. If such Lender does not pay such corresponding amount
forthwith upon the Administrative Agent's demand therefor, the Administrative
Agent will promptly notify the Borrower, and the Borrower shall immediately pay
such corresponding amount to the Administrative Agent. The Administrative Agent
shall also be entitled to recover from the Lender or the Borrower, as the case
may be, interest on such corresponding amount in respect of each day from the
date such corresponding amount was made available by the Administrative Agent to
the Borrower to the date such corresponding amount is recovered by the
Administrative Agent at a per annum rate equal to (a) from the Borrower at the
applicable rate for such Loan pursuant to the Notice of Borrowing and (b) from a
Lender at the Federal Funds Rate.

         2.4 CONTINUATIONS AND CONVERSIONS.

         The Borrower shall have the option, on any Business Day, to continue
existing Eurodollar Loans for a subsequent Interest Period, to convert Base Rate
Loans into Eurodollar Loans or to convert Eurodollar Loans into Base Rate Loans;
provided, however, that (a) each such continuation or conversion must be
requested by the Borrower pursuant to a written Notice of
Continuation/Conversion, in the form of Exhibit 2.4, in compliance with the
terms set forth below, (b) except as provided in Section 4.1, Eurodollar Loans
may only be continued or converted into Base Rate Loans on the last day of the
Interest Period applicable thereto, (c) at the election of the Required Lenders,
Eurodollar Loans may not be continued nor may Base Rate Loans be converted into
Eurodollar Loans during the existence and continuation of an Event of Default
and (d) any request to extend a Eurodollar Loan that fails to comply with the
terms hereof or any failure to request an extension of a Eurodollar Loan at the
end of an Interest Period shall constitute a conversion to a Base Rate Loan on
the last day of the applicable Interest Period. Each continuation or conversion
must be requested by the Borrower no later than 11:00 a.m. (i) on the date for a
requested conversion of a Eurodollar Loan to a Base Rate Loan or (ii) three
Business Days prior to the date for a requested continuation of a Eurodollar
Loan or conversion of a Base Rate Loan to a Eurodollar Loan, in each case
pursuant to a written Notice of Continuation/Conversion submitted to the
Administrative Agent which shall set forth (A) whether the Borrower wishes to
continue or convert such Loans and (B) if the request is to

                                       14
<PAGE>

continue a Eurodollar Loan or convert a Base Rate Loan to a Eurodollar Loan, the
Interest Period applicable thereto.

         2.5 MINIMUM AMOUNTS.

         Each request for a Loan or a conversion or continuation hereunder shall
be subject to the following requirements: (a) each Eurodollar Loan shall be in a
minimum of $5,000,000 (and in integral multiples of $1,000,000 in excess
thereof), (b) each Base Rate Loan shall be in a minimum amount of the lesser of
$5,000,000 (and in integral multiples of $1,000,000 in excess thereof) or the
remaining amount of the Aggregate Commitment available to be borrowed and (c) no
more than five Eurodollar Loans shall be outstanding hereunder at any one time.
For the purposes of this Section 2.5, all Eurodollar Loans with the same
Interest Periods that begin and end on the same date shall be considered as one
Eurodollar Loan, but Eurodollar Loans with different Interest Periods, even if
they begin on the same date, shall be considered separate Eurodollar Loans.

         2.6 REDUCTIONS OF AGGREGATE COMMITMENT.

         Upon at least three Business Days' prior written notice, the Borrower
shall have the right to permanently terminate or reduce the aggregate unused
amount of the Aggregate Commitment at any time or from time to time; provided
that (a) each partial reduction shall be in an aggregate amount at least equal
to $5,000,000 and in integral multiples of $1,000,000 above such amount and (b)
no reduction shall be made which would reduce the Aggregate Commitment to an
amount less than the sum of the then outstanding Loans. Any reduction in (or
termination of) the Aggregate Commitment shall be permanent and may not be
reinstated.

         2.7 NOTES.

         The Loans made by any Lender may, at the request of a Lender, be
evidenced by a promissory note of the Borrower payable to such Lender in
substantially the form of Exhibit 2.7 (the "Notes").

         The date, amount, type, interest rate and duration of Interest Period
(if applicable) of each Loan made by each Lender to the Borrower, and each
payment made on account of the principal thereof, shall be recorded by such
Lender on its books; provided that the failure of such Lender to make any such
recordation or endorsement shall not affect the obligations of the Borrower to
make a payment when due of any amount owing hereunder or under any Note in
respect of the Loans to be evidenced by such Note, and each such recordation or
endorsement shall be conclusive and binding absent manifest error.

                                   SECTION 3.

                                    PAYMENTS

         3.1 INTEREST.

                  (a) Interest Rate.

                           (i) All Base Rate Loans shall accrue interest at the
                  Base Rate plus the Applicable Percentage.

                           (ii) All Eurodollar Loans shall accrue interest at
                  the Adjusted Eurodollar Rate applicable to each Eurodollar
                  Loan.

                  (b) Default Rate of Interest. Upon the occurrence, and during
         the continuation, of an Event of Default under Section 9.1(a) or, at
         the request of the Required Lenders, any other Event of Default, the
         principal of and, to the extent permitted by law, interest on the Loans
         and any other amounts owing hereunder or under the other Credit
         Documents shall bear interest, payable on demand, at a per annum rate
         equal to two percent (2%) plus the rate which would otherwise be
         applicable (or if no rate is applicable, then the rate for Loans that
         are Base Rate Loans plus two percent (2%) per annum).

                  (c) Interest Payments. Interest on Loans shall be due and
         payable in arrears on each Interest Payment Date.

         3.2 PREPAYMENTS.

                  (a) Voluntary Prepayments. The Borrower shall have the right
         to prepay Loans in whole or in part from time to time without premium
         or penalty; provided, however, that (i) Eurodollar Loans may only be
         prepaid on three Business Days' prior written notice to the
         Administrative Agent and any prepayment of Eurodollar Loans will be
         subject to Section 4.3; and (ii) each such partial prepayment of Loans
         shall be in the minimum principal amount of $5,000,000 and in integral
         multiples of $1,000,000 above such amount. Amounts prepaid hereunder
         shall be applied as the Borrower may elect; provided that if the
         Borrower fails to specify the application of a voluntary prepayment
         then such prepayment shall be applied first to Base Rate Loans, and
         then to Eurodollar Loans in direct order of Interest Period maturities
         pro rata among all Lenders holding same.

                  (b) Mandatory Prepayments. If at any time the amount of Loans
         outstanding exceeds the Aggregate Commitment, the Borrower shall
         immediately make a principal payment to the Administrative Agent in the
         manner and in an amount such that the amount of Loans outstanding is
         less than or equal to the Aggregate Commitment. Any payments made under
         this Section 3.2(b) shall be subject to Section 4.3 and shall be
         applied first to Base Rate Loans and then to Eurodollar Loans in direct
         order of Interest Period maturities pro rata among all Lenders holding
         same.

                                       16
<PAGE>

         3.3 PAYMENT IN FULL AT MATURITY.

         On the Maturity Date, the entire outstanding principal balance of all
Loans, together with accrued but unpaid interest and all other sums owing under
this Credit Agreement and the other Credit Documents, shall be due and payable
in full, unless accelerated sooner pursuant to Section 9.2.

         3.4 FEES.

                  (a) Unused Fees.

                           (i) In consideration of the Aggregate Commitment
                  being made available by the Lenders hereunder, the Borrower
                  agrees to pay to the Administrative Agent, for the pro rata
                  benefit of each Lender, a per annum fee equal to the
                  Applicable Percentage for Unused Fees (as set forth on the
                  Pricing Schedule) on the Unused Aggregate Commitment (the
                  "Unused Fees").

                           (ii) The accrued Unused Fees shall be due and payable
                  in arrears five Business Days after the end of each fiscal
                  quarter of the Borrower (as well as on the Maturity Date) for
                  the immediately preceding fiscal quarter (or portion thereof),
                  beginning with the first of such dates to occur after the
                  Effective Date.

                  (b) Utilization Fees. For each day that the principal amount
         of outstanding Loans hereunder shall exceed an amount equal to fifty
         percent (50%) of the Aggregate Commitment, the Borrower shall pay to
         the Administrative Agent, for the pro rata benefit of the Lenders, a
         per annum fee equal to the Applicable Percentage for Utilization Fees
         (as set forth on the Pricing Schedule) on the outstanding principal
         balance of the Loans (the "Utilization Fees"). The Utilization Fees, if
         any, shall be due and payable in arrears five Business Days after the
         end of each fiscal quarter of the Borrower (as well as on the Maturity
         Date) for the immediately preceding fiscal quarter (or portion
         thereof), beginning with the first of such dates to occur after the
         Effective Date.

                  (c) Administrative Fees. The Borrower agrees to pay to the
         Administrative Agent, for its own account, an annual fee as agreed to
         between the Borrower and the Administrative Agent in the Fee Letter.

         3.5 PLACE AND MANNER OF PAYMENTS.

         All payments of principal, interest, fees, expenses and other amounts
to be made by the Borrower under this Credit Agreement shall be made
unconditionally and without setoff, deduction, defense, recoupment or
counterclaim and received not later than 2:00 p.m. on the date when due, in
Dollars and in immediately available funds, by the Administrative Agent at the
Agency Services Address. In the event any such payment shall be due on a day
that is not a Business Day, the applicable payment date shall be the next
succeeding Business Day, except, with respect to Eurodollar Loans, if the next
succeeding Business Day shall fall in the next succeeding calendar month, then
such payment shall be due on the next preceding Business Day. The Borrower
shall, at the time it makes any payment under this Credit Agreement, specify to
the Administrative Agent, the Loans, fees or other amounts payable by the
Borrower hereunder

                                       17
<PAGE>

to which such payment is to be applied (and in the event that it fails to
specify, or if such application would be inconsistent with the terms hereof, the
Administrative Agent shall distribute such payment to the Lenders in such manner
as it reasonably determines in its sole discretion.)

         3.6 PRO RATA TREATMENT.

         Except to the extent otherwise provided herein, all Loans, each payment
or prepayment of principal of any Loan, each payment of interest on the Loans,
each payment of Unused Fees, each payment of Utilization Fees, each reduction of
the Aggregate Commitment, and each conversion or continuation of any Loans,
shall be allocated pro rata among the Lenders in accordance with the respective
Commitment Percentages; provided that, if any Lender shall have failed to pay
its applicable pro rata share of any Loan, then any amount to which such Lender
would otherwise be entitled pursuant to this Section 3.6 shall instead be
payable to the Administrative Agent until the share of such Loan not funded by
such Lender has been repaid and any interest owed by such Lender as a result of
such failure to fund has been paid; and provided further, that in the event any
amount paid to any Lender pursuant to this Section 3.6 is rescinded or must
otherwise be returned by the Administrative Agent, each Lender shall, upon the
request of the Administrative Agent, repay to the Administrative Agent the
amount so paid to such Lender, with interest for the period commencing on the
date such payment is returned by the Administrative Agent until the date the
Administrative Agent receives such repayment at a rate per annum equal to,
during the period to but excluding the date two Business Days after such
request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent
(2%) per annum.

         3.7 COMPUTATIONS OF INTEREST AND FEES.

                  (a) Except for Base Rate Loans accruing interest at the Prime
         Rate, which interest shall be computed on the basis of a 365 or 366 day
         year as the case may be, all computations of interest and fees
         hereunder shall be made on the basis of the actual number of days
         elapsed over a year of 360 days. Interest shall accrue from the date a
         Loan is made until the date such Loan is repaid or continued or
         converted pursuant to Section 2.4.

                  (b) It is the intent of the Lenders and the Borrower to
         conform to and contract in strict compliance with applicable usury law
         from time to time in effect. All agreements between the Lenders and the
         Borrower are hereby limited by the provisions of this paragraph which
         shall override and control all such agreements, whether now existing or
         hereafter arising and whether written or oral. In no way, nor in any
         event or contingency (including but not limited to prepayment or
         acceleration of the maturity of any obligation), shall the interest
         taken, reserved, contracted for, charged, or received under this Credit
         Agreement, under the Notes or otherwise, exceed the maximum nonusurious
         amount permissible under applicable law. If, from any possible
         construction of any of the Credit Documents or any other document,
         interest would otherwise be payable in excess of the maximum
         nonusurious amount, any such construction shall be subject to the
         provisions of this paragraph and interest owing pursuant to such
         documents shall be automatically reduced to the maximum nonusurious
         amount permitted under applicable law, without the necessity of
         execution of any amendment or new document.

                                       18
<PAGE>

         If any Lender shall ever receive anything of value which is
         characterized as interest on the Loans under applicable law and which
         would, apart from this provision, be in excess of the maximum lawful
         amount, an amount equal to the amount which would have been excessive
         interest shall, without penalty, be applied to the reduction of the
         principal amount owing on the Loans and not to the payment of interest,
         or refunded to the Borrower or the other payor thereof if and to the
         extent such amount which would have been excessive exceeds such unpaid
         principal amount of the Loans. The right to demand payment of the Loans
         or any other indebtedness evidenced by any of the Credit Documents does
         not include the right to receive any interest which has not otherwise
         accrued on the date of such demand, and the Lenders do not intend to
         charge or receive any unearned interest in the event of such demand.
         All interest paid or agreed to be paid to the Lenders with respect to
         the Loans shall, to the extent permitted by applicable law, be
         amortized, prorated, allocated, and spread throughout the full stated
         term (including any renewal or extension) of the Loans so that the
         amount of interest on account of such indebtedness does not exceed the
         maximum nonusurious amount permitted by applicable law.

         3.8 SHARING OF PAYMENTS.

         Each Lender agrees that, in the event that any Lender shall obtain
payment in respect of any Loan or any other obligation owing to such Lender
under this Credit Agreement through the exercise of a right of set-off, banker's
lien, counterclaim or otherwise (including, but not limited to, pursuant to the
Bankruptcy Code) in excess of its pro rata share as provided for in this Credit
Agreement, such Lender shall promptly purchase from the other Lenders a
participation in such Loans and other obligations, in such amounts and with such
other adjustments from time to time, as shall be equitable in order that all
Lenders share such payment in accordance with their respective ratable shares as
provided for in this Credit Agreement. Each Lender further agrees that if a
payment to a Lender (which is obtained by such Lender through the exercise of a
right of set-off, banker's lien, counterclaim or otherwise) shall be rescinded
or must otherwise be restored, each Lender which shall have shared the benefit
of such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit to each Lender whose payment shall have been rescinded
or otherwise restored. The Borrower agrees that any Lender so purchasing such a
participation may, to the fullest extent permitted by law, exercise all rights
of payment, including set-off, banker's lien or counterclaim, with respect to
such participation as fully as if such Lender were a holder of such Loan or
other obligation in the amount of such participation. Except as otherwise
expressly provided in this Credit Agreement, if any Lender shall fail to remit
to the Administrative Agent or any other Lender an amount payable by such Lender
to the Administrative Agent or such other Lender pursuant to this Credit
Agreement on the date when such amount is due, such payments shall accrue
interest thereon, for each day from the date such amount is due until the day
such amount is paid to the Administrative Agent or such other Lender, at a rate
per annum equal to the Federal Funds Rate. If under any applicable bankruptcy,
insolvency or other similar law, any Lender receives a secured claim in lieu of
a setoff to which this Section 3.8 applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Lenders under this Section 3.8 to share in the
benefits of any recovery on such secured claim.

                                       19
<PAGE>

         3.9 EVIDENCE OF DEBT.

                  (a) Each Lender shall maintain an account or accounts
         evidencing each Loan made by such Lender to the Borrower from time to
         time, including the amounts of principal and interest payable and paid
         to such Lender from time to time under this Credit Agreement. Each
         Lender will make reasonable efforts to maintain the accuracy of its
         account or accounts and to promptly update its account or accounts from
         time to time, as necessary.

                  (b) The Administrative Agent shall maintain the Register
         pursuant to Section 11.3(c), and a subaccount for each Lender, in which
         Register and subaccounts (taken together) shall be recorded (i) the
         amount, type and Interest Period of each such Loan hereunder, (ii) the
         amount of any principal or interest due and payable or to become due
         and payable to each Lender hereunder and (iii) the amount of any sum
         received by the Administrative Agent hereunder from or for the account
         of the Borrower and each Lender's share thereof. The Administrative
         Agent will make reasonable efforts to maintain the accuracy of the
         subaccounts referred to in the preceding sentence and to promptly
         update such subaccounts from time to time, as necessary.

                  (c) The entries made in the accounts, Register and subaccounts
         maintained pursuant to subsection (b) of this Section 3.9 (and, if
         consistent with the entries of the Administrative Agent, subsection
         (a)) shall be prima facie evidence of the existence and amounts of the
         obligations of the Borrower therein recorded; provided, however, that
         the failure of any Lender or the Administrative Agent to maintain any
         such account, such Register or such subaccount, as applicable, or any
         error therein, shall not in any manner affect the obligation of the
         Borrower to repay the Loans made by such Lender in accordance with the
         terms hereof.

                                   SECTION 4.

                      ADDITIONAL PROVISIONS REGARDING LOANS

         4.1 EURODOLLAR LOAN PROVISIONS.

                  (a) Unavailability. In the event that the Administrative Agent
         shall have determined in good faith (i) that U.S. dollar deposits in
         the principal amounts requested with respect to a Eurodollar Loan are
         not generally available in the London interbank Eurodollar market or
         (ii) that reasonable means do not exist for ascertaining the Eurodollar
         Rate, the Administrative Agent shall, as soon as practicable
         thereafter, give notice of such determination to the Borrower and the
         Lenders. In the event of any such determination under clauses (i) or
         (ii) above, until the Administrative Agent shall have advised the
         Borrower and the Lenders that the circumstances giving rise to such
         notice no longer exist, (A) any request by the Borrower for Eurodollar
         Loans shall be deemed to be a request for Base Rate Loans, (B) any
         request by the Borrower for conversion into or continuation of
         Eurodollar Loans shall be deemed to be a request for conversion into or
         continuation of Base Rate Loans and (C) any Loans that were to be
         converted or

                                       20
<PAGE>

         continued as Eurodollar Loans on the first day of an Interest Period
         shall be converted to or continued as Base Rate Loans.

                  (b) Change in Legality.

                           (i) Notwithstanding any other provision herein, if
                  any change, after the date hereof, in any law, governmental
                  rule, regulation, guideline or order (including the
                  introduction of any new law, governmental rule, regulation,
                  guideline or order) or in the interpretation or administration
                  thereof by any Governmental Authority charged with the
                  interpretation or administration thereof shall make it
                  unlawful for any Lender to make or maintain any Eurodollar
                  Loan or to give effect to its obligations as contemplated
                  hereby with respect to any Eurodollar Loan, then, by written
                  notice to the Borrower and to the Administrative Agent, such
                  Lender may:

                                    (A) declare that Eurodollar Loans, and
                           conversions to or continuations of Eurodollar Loans,
                           will not thereafter be made by such Lender hereunder,
                           whereupon any request by the Borrower for, or for
                           conversion into or continuation of, Eurodollar Loans
                           shall, as to such Lender only, be deemed a request
                           for, or for conversion into or continuation of, Base
                           Rate Loans, unless such declaration shall be
                           subsequently withdrawn; and

                                    (B) require that all outstanding Eurodollar
                           Loans made by it be converted to Base Rate Loans in
                           which event all such Eurodollar Loans shall be
                           automatically converted to Base Rate Loans.

                  In the event any Lender shall exercise its rights under clause
         (A) or (B) above, all payments and prepayments of principal which would
         otherwise have been applied to repay the Eurodollar Loans that would
         have been made by such Lender or the converted Eurodollar Loans of such
         Lender shall instead be applied to repay the Base Rate Loans made by
         such Lender in lieu of, or resulting from the conversion of, such
         Eurodollar Loans.

                  (c) Requirements of Law. If at any time a Lender shall incur
         increased costs or reductions in the amounts received or receivable
         hereunder with respect to the making, the commitment to make or the
         maintaining of any Eurodollar Loan because of (i) any change after the
         date hereof, in any law, governmental rule, regulation, guideline or
         order (including the introduction of any new law, governmental rule,
         regulation, guideline or order) or in the interpretation or
         administration thereof by any Governmental Authority charged with the
         interpretation or administration thereof, including, without
         limitation, the imposition, modification or deemed applicability of any
         reserves, deposits or similar requirements (such as, for example, but
         not limited to, a change in official reserve requirements, but, in all
         events, excluding reserves required under Regulation D to the extent
         included in the computation of the Adjusted Eurodollar Rate) or (ii)
         other circumstances affecting the London interbank Eurodollar market;
         then (A) the Lender shall promptly notify the Administrative Agent and
         the Borrower and shall designate a

                                       21
<PAGE>

         different lending office of such Lender if such designation will avoid
         or reduce the amount of such increased costs, or reductions in amounts
         receivable and such designation will not, in such Lender's sole
         discretion, be otherwise disadvantageous to such Lender and (B) the
         Borrower shall promptly pay to such Lender such additional amounts (in
         the form of an increased rate of, or a different method of calculating,
         interest or otherwise as such Lender may determine in its sole
         discretion) as may be required to compensate such Lender for such
         increased costs or reductions in amounts receivable hereunder.

         A certificate of a Lender setting forth the amount or amounts necessary
to compensate such Lender as specified in subsection (c) of this Section shall
be required to be delivered to the Borrower as a condition to the obligations of
the Borrower under such subsection and shall set forth a calculation by an
officer of such Lender in reasonable detail. Each determination and calculation
made by a Lender under this Section 4.1 shall, absent manifest error, be binding
and conclusive on the parties hereto. Failure or delay on the part of any Lender
to demand compensation pursuant to the foregoing provisions of this Section
shall not constitute a waiver of such Lender's right to demand such
compensation, provided that the Borrower shall not be required to compensate a
Lender pursuant to the foregoing provisions of this Section for any increased
costs incurred or reductions suffered more than nine months prior to the date
that such Lender notifies the Borrower of the event giving rise to such
increased costs or reductions and of such Lender's intention to claim
compensation therefor (except that, if a change in law, rule, regulation,
guideline or order, or in the interpretation or administration thereof, giving
rise to such increased costs or reductions is retroactive, then the nine-month
period referred to above shall be extended to include the period of retroactive
effect thereof). Any conversions of Eurodollar Loans made pursuant to this
Section 4.1 shall subject the Borrower to the payments required by Section 4.3.
This Section 4.1 shall survive termination of this Credit Agreement and the
other Credit Documents and the payment of the Loans and all other amounts
payable hereunder.

         4.2 CAPITAL ADEQUACY.

         If any Lender has determined in good faith that the adoption or
effectiveness, after the date hereof, of any applicable law, rule or regulation
regarding capital adequacy, or any change therein (after the date hereof), or
any change (after the date hereof) in the interpretation or administration
thereof by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by such Lender
(or its parent corporation) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's (or parent corporation's) capital or assets as a
consequence of its commitments or obligations hereunder to a level below that
which such Lender (or its parent corporation) could have achieved but for such
adoption, effectiveness, change or compliance (taking into consideration such
Lender's (or parent corporation's) policies with respect to capital adequacy),
then, upon notice from such Lender, the Borrower shall promptly pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction. A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender as specified in this Section 4.2 shall be
required to be delivered to the Borrower as a condition to the obligations of
the Borrower under this Section 4.2 and shall set forth a calculation by an
officer of such Lender in reasonable detail. Each determination by any

                                       22
<PAGE>

such Lender of amounts owing under this Section 4.2 shall, absent manifest
error, be conclusive and binding on the parties hereto. Failure or delay on the
part of any Lender to demand compensation pursuant to the foregoing provisions
of this Section shall not constitute a waiver of such Lender's right to demand
such compensation, provided that the Borrower shall not be required to
compensate a Lender pursuant to the foregoing provisions of this Section for any
increased costs incurred or reductions suffered more than nine months prior to
the date that such Lender notifies the Borrower of the event giving rise to such
increased costs or reductions and of such Lender's intention to claim
compensation therefor (except that, if a change in law, rule, regulation, or in
the interpretation or administration thereof, giving rise to such increased
costs or reductions is retroactive, then the nine-month period referred to above
shall be extended to include the period of retroactive effect thereof). This
Section 4.2 shall survive termination of this Credit Agreement and the other
Credit Documents and the payment of the Loans and all other amounts payable
hereunder.

         4.3 COMPENSATION.

         The Borrower promises to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur as a
consequence of (a) default by the Borrower in the making of a borrowing of,
conversion into or continuation of a Eurodollar Loan after the Borrower has
given a notice requesting the same in accordance with the provisions of this
Credit Agreement, (b) default by the Borrower in making any prepayment of a
Eurodollar Loan after the Borrower has given a notice thereof in accordance with
the provisions of this Credit Agreement, (c) the making of a prepayment of a
Eurodollar Loan on a day which is not the last day of an Interest Period with
respect thereto and (d) the payment, continuation or conversion of a Eurodollar
Loan on a day which is not the last day of the Interest Period applicable
thereto or the failure to repay a Eurodollar Loan when required by the terms of
this Credit Agreement. Each determination by any such Lender of amounts owing
under this Section 4.3 shall, absent manifest error, be conclusive and binding
on the parties hereto. This Section 4.3 shall survive the termination of this
Credit Agreement and the other Credit Documents and the payment of the Loans and
all other amounts payable hereunder.

         4.4 TAXES.

                  (a) Except as provided below in this Section 4.4, all payments
         made by the Borrower under this Credit Agreement and any Notes shall be
         made free and clear of, and without deduction or withholding for or on
         account of, any present or future income, stamp or other taxes, levies,
         imposts, duties, charges, fees, deductions or withholdings, now or
         hereafter imposed, levied, collected, withheld or assessed by any
         court, or governmental body, agency or other official, excluding taxes
         measured by or imposed upon the net income of any Lender or its
         applicable lending office, or any branch or affiliate thereof, and all
         franchise taxes, branch taxes, taxes on doing business or taxes on the
         capital or net worth of any Lender or its applicable lending office, or
         any branch or affiliate thereof, in each case imposed in lieu of net
         income taxes: (i) by the jurisdiction under the laws of which such
         Lender, applicable lending office, branch or affiliate is organized or
         is located, or in which its principal executive office is located, or
         any nation within which such jurisdiction is located or any political
         subdivision thereof; or (ii) by reason of any connection between the
         jurisdiction imposing such tax and such Lender,

                                       23
<PAGE>

         applicable lending office, branch or affiliate other than a connection
         arising solely from such Lender having executed, delivered or performed
         its obligations, or received payment under or enforced, this Credit
         Agreement or any Notes. If any such non-excluded taxes, levies,
         imposts, duties, charges, fees, deductions or withholdings
         ("Non-Excluded Taxes") are required to be withheld from any amounts
         payable to an Administrative Agent or any Lender hereunder or under any
         Notes, (A) the amounts so payable to the Administrative Agent or such
         Lender shall be increased to the extent necessary to yield to the
         Administrative Agent or such Lender (after payment of all Non-Excluded
         Taxes) interest or any such other amounts payable hereunder at the
         rates or in the amounts specified in this Credit Agreement and any
         Notes, provided, however, that the Borrower shall be entitled to deduct
         and withhold any Non-Excluded Taxes and shall not be required to
         increase any such amounts payable to any Lender that is not organized
         under the laws of the United States of America or a state thereof if
         such Lender fails to comply with the requirements of paragraph (b) of
         this Section 4.4 whenever any Non-Excluded Taxes are payable by the
         Borrower, and (B) as promptly as possible after requested, the Borrower
         shall send to the Administrative Agent for its own account or for the
         account of such Lender, as the case may be, a certified copy of an
         original official receipt received by the Borrower showing payment
         thereof. If the Borrower fails to pay any Non-Excluded Taxes when due
         to the appropriate taxing authority or fails to remit to the
         Administrative Agent the required receipts or other required
         documentary evidence, the Borrower shall indemnify the Administrative
         Agent and any Lender for any incremental Non-Excluded Taxes, interest
         or penalties that may become payable by the Administrative Agent or any
         Lender as a result of any such failure. The agreements in this Section
         4.4 shall survive the termination of this Credit Agreement and the
         payment of the Loans and all other amounts payable hereunder.

                  (b) Each Lender that is not organized under the laws of the
         United States of America or a state thereof shall:

                           (i)      (A) on or before the date of any payment by
                  the Borrower under this Credit Agreement or the Notes to such
                  Lender, deliver to the Borrower and the Administrative Agent
                  (x) two duly completed copies of United States Internal
                  Revenue Service Form W8-BEN or W8-ECI, or successor applicable
                  form, as the case may be, certifying that it is entitled to
                  receive payments under this Credit Agreement and any Notes
                  without deduction or withholding of any United States federal
                  income taxes and (y) an Internal Revenue Service Form W-8 or
                  W-9, or successor applicable form, as the case may be,
                  certifying that it is entitled to an exemption from United
                  States backup withholding tax;

                                    (B) deliver to the Borrower and the
                  Administrative Agent two further copies of any such form or
                  certification on or before the date that any such form or
                  certification expires or becomes obsolete and after the
                  occurrence of any event requiring a change in the most recent
                  form previously delivered by it to the Borrower; and

                                       24
<PAGE>

                                    (C) obtain such extensions of time for
                  filing and complete such forms or certifications as may
                  reasonably be requested by the Borrower or the Administrative
                  Agent; or

                           (ii) in the case of any such Lender that is not a
                  "bank" within the meaning of Section 881(c)(3)(A) of the
                  Internal Revenue Code, (A) represent to the Borrower (for the
                  benefit of the Borrower and the Administrative Agent) that it
                  is not a bank within the meaning of Section 881 (c)(3)(A) of
                  the Internal Revenue Code, (B) agree to furnish to the
                  Borrower, on or before the date of any payment by the
                  Borrower, with a copy to the Administrative Agent, two
                  accurate and complete original signed copies of Internal
                  Revenue Service Form W-8, or successor applicable form
                  certifying to such Lender's legal entitlement at the date of
                  such certificate to an exemption from U.S. withholding tax
                  under the provisions of Section 881(c) of the Internal Revenue
                  Code with respect to payments to be made under this Credit
                  Agreement and any Notes (and to deliver to the Borrower and
                  the Administrative Agent two further copies of such form on or
                  before the date it expires or becomes obsolete and after the
                  occurrence of any event requiring a change in the most
                  recently provided form and, if necessary, obtain any
                  extensions of time reasonably requested by the Borrower or the
                  Administrative Agent for filing and completing such forms),
                  and (C) agree, to the extent legally entitled to do so, upon
                  reasonable request by the Borrower, to provide to the Borrower
                  (for the benefit of the Borrower and the Administrative Agent)
                  such other forms as may be reasonably required in order to
                  establish the legal entitlement of such Lender to an exemption
                  from withholding with respect to payments under this Credit
                  Agreement and any Notes.

                           Notwithstanding the above, if any change in treaty,
                  law or regulation has occurred after the date such Person
                  becomes a Lender hereunder which renders all such forms
                  inapplicable or which would prevent such Lender from duly
                  completing and delivering any such form with respect to it and
                  such Lender so advises the Borrower and the Administrative
                  Agent, then such Lender shall be exempt from such
                  requirements. Each Person that shall become a Lender or a
                  participant of a Lender pursuant to Section 11.3 shall, upon
                  the effectiveness of the related transfer, be required to
                  provide all of the forms, certifications and statements
                  required pursuant to this subsection (b); provided that in the
                  case of a participant of a Lender, the obligations of such
                  participant of a Lender pursuant to this subsection (b) shall
                  be determined as if the participant of a Lender were a Lender
                  except that such participant of a Lender shall furnish all
                  such required forms, certifications and statements to the
                  Lender from which the related participation shall have been
                  purchased.

                  (c) If the Administrative Agent or any Lender receives a
         refund of any taxes as to which it has been indemnified by the Borrower
         or with respect to which the Borrower has paid additional amounts
         pursuant to this Section, it shall pay to the Borrower an amount equal
         to such refund (but only to the extent of indemnity payments made, or
         additional amounts paid, by the Borrower under this Section with
         respect to the taxes giving rise to such refund), net of all
         out-of-pocket expenses of the Administrative

                                       25
<PAGE>

         Agent or such Lender, as the case may be, and without interest (other
         than any interest paid by the relevant Governmental Authority with
         respect to such refund), provided that the Borrower, upon the request
         of the Administrative Agent or such Lender, agrees to repay the amount
         paid over to the Borrower (plus any penalties, interest or other
         charges imposed by the relevant Governmental Authority) to the
         Administrative Agent or such Lender in the event the Administrative
         Agent or such Lender is required to repay such refund to such
         Governmental Authority. This subsection shall not be construed to
         require the Administrative Agent or any Lender to make available its
         tax returns (or any other information relating to its taxes that it
         deems confidential) to the Borrower or any other Person.

         4.5 MITIGATION; REPLACEMENT OF LENDERS.

                  (a) If any Lender requests compensation under Section 4.1 or
         Section 4.2, or the Borrower is required to pay any additional amount
         to any Lender or any Governmental Authority for the account of any
         Lender pursuant to Section 4.4, or if any Lender gives a notice
         pursuant to Section 4.1(b), then such Lender shall use reasonable
         efforts to designate a different lending office for funding or booking
         its Loans hereunder or to assign its rights and obligations hereunder
         to another of its offices, branches or affiliates, if, in the judgment
         of such Lender, such designation or assignment (i) would eliminate or
         reduce amounts payable pursuant to Section 4.1, Section 4.2 or Section
         4.4, as the case may be, in the future, or eliminate the need for the
         notice pursuant to Section 4.1(b), as applicable, and (ii) in each
         case, would not subject such Lender to any unreimbursed cost or expense
         and would not otherwise be disadvantageous to such Lender. The Borrower
         hereby agrees to pay all reasonable costs and expenses incurred by any
         Lender in connection with any such designation or assignment.

                  (b) If any Lender requests compensation under Section 4.1 or
         Section 4.2, or if the Borrower is required to pay any additional
         amount to any Lender or any Governmental Authority for the account of
         any Lender pursuant to Section 4.4, or if any Lender is a Defaulting
         Lender, then the Borrower may, at its sole expense and effort, upon
         notice to such Lender and the Administrative Agent, require such Lender
         to assign and delegate, without recourse (in accordance with and
         subject to the restrictions contained in, and consents required by,
         Section 11.3(b)), all of its interests, rights and obligations under
         this Credit Agreement and the related Credit Documents to an assignee
         that shall assume such obligations (which assignee may be another
         Lender, if a Lender accepts such assignment), provided that:

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

                           (ii) in the case of any such assignment resulting
                  from a claim for compensation under Section 4.1 or 4.2, such
                  assignment will result in a reduction in such compensation or
                  payments thereafter; and

                                       26
<PAGE>

                           (iii) such assignment does not conflict with
                  applicable laws, rules, regulations or guidelines.

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

                                   SECTION 5.

         Except as would not result or be reasonably expected to result in a
Material Adverse Effect:

                  (a) During the five-year period prior to the date on which
         this representation is made or deemed made: (i) no Termination Event
         has occurred, and, to the best knowledge of the Borrower, no event or
         condition has occurred or exists as a result of which any Termination
         Event is reasonably expected to occur, with respect to any Plan; (ii)
         no "accumulated funding deficiency," as such term is defined in Section
         302 of ERISA and Section 412 of the Code, whether or not waived, has
         occurred with respect to any Plan; (iii) each Plan has been maintained,
         operated, and funded in material compliance with its own terms and in

         Borrower to be incurred under Sections 4062, 4063 or 4064 of ERISA with
         respect to any Single Employer Plan by the Borrower or any of its

         annual valuation date prior to the date on which this representation is

         406 of ERISA or Section 4975 of the Code) or breach of fiduciary
         responsibility has occurred with respect to a Plan which has subjected
         or is reasonably likely to subject the Borrower or any ERISA Affiliate
         to any liability under Sections 406, 407, 409, 502(i), or 502(l) of
         ERISA or Section 4975 of the Code, or under any agreement or other
         instrument pursuant to which the Borrower or any ERISA Affiliate has
         agreed or is required to indemnify any person against any such
         liability.

                  (f) The present value (determined using actuarial and other
         assumptions which are reasonable with respect to the benefits provided
         and the employees

                                       32
<PAGE>

         all such Plans allocable to such benefits, are reflected on the
         financial statements referenced in Section 7.1 in accordance with FASB

                  (g) Each Plan which is a welfare plan (as defined in Section
         3(1) of ERISA) to which Sections 601-609 of ERISA and Section 4980B of
         the Code apply has been administered in compliance in all material
         respects with such sections.

         6.14 USE OF PROCEEDS.

         The proceeds of the Loans hereunder will be used solely for the
purposes specified in Section 7.8. None of such proceeds will be used for the

governing body) or stockholders, as appropriate, of such Person has approved
such acquisition.

         6.15 GOVERNMENT REGULATION.

                  (a) No proceeds of the Loans will be used, directly or
         indirectly, for the purpose of purchasing or carrying any "margin
         stock" within the meaning of Regulation U, or for the purpose of
         purchasing or carrying or trading in any securities. If requested by
         any Lender or the Administrative Agent, the Borrower will furnish to
         the Administrative Agent and each Lender a statement to the foregoing
         effect in conformity with the requirements of FR Form U-1 referred to
         in Regulation U. No indebtedness being reduced or retired out of the
         proceeds of the Loans was or will be incurred for the purpose of
         purchasing or carrying any margin stock within the meaning of
         Regulation U or any "margin security" within the meaning of Regulation
         T. "Margin stock" within the meaning of Regulation U does not
         constitute more than 25% of the value of the consolidated assets of the
         Borrower and its Subsidiaries.

                  (b) Neither the Borrower nor any of its Subsidiaries is (i) an
         "investment company" registered or required to be registered under the

         company" of a "holding company", or an "affiliate" of a "holding

         meaning of the Public Utility Holding Company Act of 1935, as amended.

         6.16 DISCLOSURE.

         Neither this Credit Agreement nor any financial statements delivered to
the Lenders nor any other document, certificate or statement furnished to the
Lenders by or on behalf of the Borrower in connection with the transactions
contemplated hereby (in each case, as modified or supplemented by other
information so furnished) contains any untrue statement of a material fact or
omits to state a material fact necessary in order to make the statements

         for each "plan year" (within the meaning of Section 3(39) of ERISA).

                  (g) Other Information. With reasonable promptness upon any
         such request, such other information regarding the business, properties

         been delivered on the date (i) on which the Borrower posts such
         documents, or provides a link thereto on the Borrower's website on the

         which such documents are posted on the Borrower's behalf on an Internet
         or intranet website, if any, to which each Lender and the
         Administrative Agent have access (whether a commercial, third party
         website or sponsored by the Administrative Agent); provided that the
         Borrower shall notify the Administrative Agent (by telecopier or
         electronic mail) of the posting of any such documents (which notice the
         Administrative Agent shall promptly forward to the Lenders).
         Notwithstanding anything contained herein, in every instance the
         Borrower shall be required to provide paper or facsimile copies of the
         officer's certificates required by Section 7.1(c) to the Administrative
         Agent. Except for such officer's certificates, the Administrative Agent
         shall have no obligation to request the delivery or to maintain copies
         of the documents referred to above, and in any event shall have no
         responsibility to monitor compliance by the Borrower with any such
         request for delivery, and each Lender shall be solely responsible for
         maintaining its copies of such documents.

such ratio (and the components thereof) as of December 31, 2004 shall exclude
(to the extent not already excluded in the definition of Consolidated Funded
Debt) then outstanding borrowings made in the fiscal quarter of the Borrower
ending on such date ("Seasonal Borrowings") as Loans under this Credit Agreement

         The Borrower will, and will cause its Subsidiaries to, do all things
necessary to preserve and keep in full force and effect its existence, rights,
franchises and authority, except where failure to do so would not or would not
reasonably be expected to have a Material Adverse Effect. The Borrower will, and
will cause its Subsidiaries to, generally maintain its properties, real and
personal, in good condition, and the Borrower and its Subsidiaries shall not
waste or otherwise permit such properties to deteriorate, reasonable wear and
tear excepted, except, in each case, where failure to do so would not or would
not reasonably be expected to have a Material Adverse Effect.

         The Borrower will, and will cause its Subsidiaries to, comply with, and
obtain all permits and licenses required by, all laws (including, without
limitation, all Environmental Laws and ERISA laws), rules, regulations and
orders, and all applicable restrictions imposed by all Governmental Authorities,
applicable to it and its property, if the failure to comply would have or would
be reasonably expected to have a Material Adverse Effect.

         7.6 PAYMENT OF TAXES AND OTHER CLAIMS.

         The Borrower will, and will cause its Subsidiaries to, pay, settle or
discharge (a) all material taxes, assessments and governmental charges or levies
imposed upon it, or upon its income or profits, or upon any of its properties,
before they shall become delinquent and (b) all lawful claims (including claims
for labor, materials and supplies) which, if unpaid, might give rise to a Lien
upon any of its properties; provided, however, that the Borrower shall not be
required to pay any such tax, assessment, charge, levy, claim or indebtedness
which is being contested in good faith by appropriate action and as to which
adequate reserves therefor, if required, have been established in accordance
with GAAP, unless the failure to make any such payment (i) would give rise to an
immediate right to foreclose or collect on a Lien securing such amounts or (ii)
would have or would reasonably be expected to have a Material Adverse Effect.

         7.7 INSURANCE.

         The Borrower will, and will cause its Subsidiaries to, at all times
maintain in full force and effect insurance (including worker's compensation
insurance, liability insurance, casualty insurance and business interruption
insurance) with insurance companies or associations rated by A.M. Best "A" or
better in such amounts and covering such risks as is usually carried by
companies engaged in similar business and owning similar properties in the same
general areas in which the Borrower and its Subsidiaries operate and/or maintain
a system or systems of self-insurance or assumption of risk which accords with
the practices of similar businesses.

         7.8 USE OF PROCEEDS.

         The proceeds of the Loans may be used solely (a) to refinance the
indebtedness under the Existing Credit Agreement and (b) for working capital,
capital expenditures and other lawful corporate purposes of the Borrower.

         7.9 AUDITS/INSPECTIONS.

         Upon reasonable prior notice and during normal business hours and no
more frequently than once during any fiscal year upon reasonable advance notice
through the Administrative Agent to the Borrower, the Borrower will permit

attorneys, and appraisers to visit and inspect the Borrower's and its
Subsidiaries' property, including their books and records, their accounts
receivable and inventory, the Borrower's and its Subsidiaries' facilities and
their other business assets, and to make photocopies or photographs thereof and
to write down and record any information such representative obtains and shall
permit the Administrative Agent or its representatives to discuss all such
matters with the officers, employees and representatives of the Borrower and its
Subsidiaries; provided, however, that when an Event of Default exists the
Administrative Agent or any Lender (or any of their respective representatives)
may do any of the foregoing at the expense of the Borrower at any time during
normal business hours.

                                   SECTION 8.

exist or be caused thereby, a Person may be merged or consolidated with or into
the Borrower so long as the Borrower shall be the continuing or surviving
corporation.

         8.3 SALE OR LEASE OF ASSETS.

         Within any period of four consecutive fiscal quarters, the Borrower
will not, nor will it permit any Subsidiary to, convey, sell, lease, transfer or

                                   SECTION 9.

         or consent to the entry of an order for relief in an involuntary case
         under any such law, or consent to the appointment or taking possession
         by a receiver, liquidator, assignee, custodian, trustee, sequestrator

         (determined without regard to whether any notice or lapse of time is
         required) any such indebtedness to become due prior to its stated
         maturity; or (B) any such indebtedness shall be declared due and
         payable, or required to be prepaid other than by a regularly scheduled
         required prepayment, or by a mandatory prepayment upon specified events
         or conditions, in each case, prior to the stated maturity thereof; or
         (C) any such indebtedness shall mature and remain unpaid.

                  (g) Judgments. One or more final judgments, orders, or decrees
         shall be entered against the Borrower involving a liability of
         $100,000,000 or more, in the aggregate (to the extent not paid or
         covered by insurance provided by a carrier who has acknowledged
         coverage) and such judgments, orders or decrees shall continue
         unsatisfied, undischarged and unstayed for a period of 90 days;
         provided that if such judgment, order or decree provides for periodic
         payments over time then the Borrower shall have a grace period of 30
         days with respect to each such periodic payment.

                  (h) ERISA. The occurrence of any of the following events or
         conditions if any of the same would be reasonably expected to result in
         a liability of an amount greater than or equal to $20,000,000: (A) any
         "accumulated funding deficiency," as such term is defined in Section
         302 of ERISA and Section 412 of the Code, whether or not waived, shall
         exist with respect to any Plan, or any lien shall arise on the assets
         of the Borrower or any ERISA Affiliate in favor of the PBGC or a Plan;
         (B) a Termination Event shall occur with respect to a Single Employer
         Plan, which is, in the reasonable opinion of the Administrative Agent,
         likely to result in the termination of such Plan for purposes of Title
         IV of ERISA; (C) a Termination Event shall occur with respect to a
         Multiemployer Plan or Multiple Employer Plan, which is, in the
         reasonable opinion of the Administrative Agent, likely to result in (i)
         the termination of such Plan for purposes of Title IV of ERISA, or (ii)
         the Borrower or any ERISA Affiliate incurring any liability in
         connection with a withdrawal from, reorganization of (within the
         meaning of Section 4241 of

                                       43
<PAGE>

         ERISA), or insolvency (within the meaning of Section 4245 of ERISA) of
         such Plan; or (D) any prohibited transaction (within the meaning of
         Section 406 of ERISA or Section 4975 of the Code) or breach of
         fiduciary responsibility shall occur which would be reasonably expected
         to subject the Borrower or any ERISA Affiliate to any liability under
         Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the
         Code, or under any agreement or other instrument pursuant to which the
         Borrower or any ERISA Affiliate has agreed or is required to indemnify
         any person against any such liability.

                  (i) Change of Control. The occurrence of any Change of
         Control.

                  (j) Bridge Credit Agreement. An "Event of Default" shall occur
         under the 364-Day Revolving Credit Agreement dated as of September 24,
         2004 among the Borrower, Bank One, NA, as administrative agent, and
         various lenders.

         9.2 ACCELERATION; REMEDIES.

         Upon the occurrence and during the continuation of an Event of Default,
the Administrative Agent may, with the consent of the Required Lenders, and
shall, upon the request and direction of the Required Lenders, by written notice
to the Borrower take any of the following actions without prejudice to the
rights of the Administrative Agent or any Lender to enforce its claims against
the Borrower, except as otherwise specifically provided for herein:

                           (i) Termination of Commitments. Declare the
                  Commitments terminated whereupon the Commitments shall be
                  immediately terminated.

                           (ii) Acceleration of Loans. Declare the unpaid amount
                  of all Borrower Obligations to be due whereupon the same shall
                  be immediately due and payable without presentment, demand,
                  protest or other notice of any kind, all of which are hereby
                  waived by the Borrower.

                           (iii) Enforcement of Rights. Enforce any and all
                  rights and interests created and existing under the Credit
                  Documents, including, without limitation, all rights of
                  set-off.

Notwithstanding the foregoing, if an Event of Default specified in Section
9.1(e) shall occur, then the Commitments shall automatically terminate and all
Loans, all accrued interest in respect thereof, all accrued and unpaid fees and
other indebtedness or obligations owing to the Lenders and the Administrative
Agent hereunder shall immediately become due and payable without the giving of
any notice or other action by the Administrative Agent or the Lenders.

Notwithstanding the fact that enforcement powers reside primarily with the
Administrative Agent, each Lender has, to the extent permitted by law, a
separate right of payment and shall be considered a separate "creditor" holding
a separate "claim" within the meaning of Section 101(5) of the Bankruptcy Code
or any other insolvency statute.

                                       44

         9.3 ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

         Notwithstanding any other provisions of this Credit Agreement, after
the occurrence of an Event of Default, all amounts collected or received by the
Administrative Agent or any Lender on account of amounts outstanding under any
of the Credit Documents shall be paid over or delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Administrative Agent or any of the Lenders in connection with
         enforcing the rights of the Lenders under the Credit Documents, pro
         rata as set forth below;

                  SECOND, to payment of any fees owed to the Administrative
         Agent, or any Lender, pro rata as set forth below;

                  THIRD, to the payment of all accrued interest payable to the
         Lenders hereunder, pro rata as set forth below;

                  FOURTH, to the payment of the outstanding principal amount of
         the Loans, pro rata as set forth below;

                  FIFTH, to all other obligations which shall have become due
         and payable under the Credit Documents and not repaid pursuant to
         clauses "FIRST" through "FOURTH" above; and

                  SIXTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category and (b) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Loans held
by such Lender bears to the aggregate then outstanding Loans) of amounts
available to be applied.

                                  SECTION 10.

                                AGENCY PROVISIONS

         10.1 APPOINTMENT.

         Each Lender hereby designates and appoints Bank One, NA as agent of
such Lender to act as specified herein and the other Credit Documents, and each
such Lender hereby authorizes the Administrative Agent, as the agent for such
Lender, to take such action on its behalf under the provisions of this Credit
Agreement and the other Credit Documents and to exercise such powers and perform
such duties as are expressly delegated by the terms hereof and of the other
Credit Documents, together with such other powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary elsewhere herein and in
the other Credit Documents, the Administrative Agent shall not have any duties
or responsibilities, except those

                                       45
<PAGE>

expressly set forth herein and therein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Credit Agreement or any of
the other Credit Documents, or shall otherwise exist against the Administrative
Agent. The provisions of this Section 10.1 are solely for the benefit of the
Administrative Agent and the Lenders and the Borrower shall not have any rights
as a third party beneficiary of the provisions hereof. In performing its
functions and duties under this Credit Agreement and the other Credit Documents,
the Administrative Agent shall act solely as agent of the Lenders and does not
assume and shall not be deemed to have assumed any obligation or relationship of
agency or trust with or for the Borrower. Any agent named herein (other than the
Administrative Agent) shall have no duties or obligations whatsoever under this
Credit Agreement or the other Credit Documents.

         10.2 DELEGATION OF DUTIES.

         The Administrative Agent may execute any of its duties hereunder or
under the other Credit Documents by or through agents or attorneys-in-fact and
shall be entitled to advice of counsel concerning all matters pertaining to such
duties. The Administrative Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

         10.3 EXCULPATORY PROVISIONS.

         Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be liable to any Lender
for any action lawfully taken or omitted to be taken by it or such Person under
or in connection herewith or in connection with any of the other Credit
Documents (except for its or such Person's own gross negligence or willful
misconduct), or responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by the Borrower
contained herein or in any of the other Credit Documents or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection herewith or in connection
with the other Credit Documents, or enforceability or sufficiency therefor of
any of the other Credit Documents, or for any failure of the Borrower to perform
its obligations hereunder or thereunder. The Administrative Agent shall not be
responsible to any Lender for the effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Credit Agreement, or any
of the other Credit Documents or for any representations, warranties, recitals
or statements made herein or therein or made by the Borrower in any written or
oral statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by the Administrative Agent to the Lenders or by or on behalf
of the Borrower to the Administrative Agent or any Lender or be required to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Loans or of the existence or possible
existence of any Default or Event of Default or to inspect the properties, books
or records of the Borrower. The Administrative Agent is not a trustee for the
Lenders and owes no fiduciary duty to the Lenders.

                                       46
<PAGE>

         10.4 RELIANCE ON COMMUNICATIONS.

         The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it in
good faith 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, without limitation, counsel to the Borrower, independent accountants
and other experts selected by the Administrative Agent with reasonable care).
The Administrative Agent may deem and treat the Lenders as the owner of its
interests hereunder for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Administrative
Agent in accordance with Section 11.3(b). The Administrative Agent shall be
fully justified in failing or refusing to take any action under this Credit
Agreement or under any of the other Credit Documents unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or under any of the other Credit Documents in accordance with a
request of the Required Lenders (or to the extent specifically provided in
Section 11.6, all the Lenders) and such request and any action taken or failure
to act pursuant thereto shall be binding upon all the Lenders (including their
successors and assigns).

         10.5 NOTICE OF DEFAULT.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or the Borrower referring
to the Credit Document, describing such Default or Event of Default and stating
that such notice is a "notice of default." In the event that the Administrative
Agent receives such a notice, the Administrative Agent shall give prompt notice
thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders.

         10.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates has made any representations or warranties to it and that no act
by the Administrative Agent or any affiliate thereof hereinafter taken,
including any review of the affairs of the Borrower, shall be deemed to
constitute any representation or warranty by the Administrative Agent to any
Lender. Each Lender represents to the Administrative Agent that it has,
independently and without reliance upon the Administrative Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
assets, operations, property, financial and other conditions, prospects and
creditworthiness of the Borrower and made its own decision to make its
Extensions of Credit hereunder and enter into this Credit Agreement. Each Lender
also represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis,

                                       47
<PAGE>

appraisals and decisions in taking or not taking action under this Credit
Agreement, and to make such investigation as it deems necessary to inform itself
as to the business, assets, operations, property, financial and other
conditions, prospects and creditworthiness of the Borrower. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent hereunder, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, assets, property, financial or
other conditions, prospects or creditworthiness of the Borrower which may come
into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates.

         10.7 INDEMNIFICATION.

         Each Lender agrees to indemnify the Administrative Agent in its
capacity as such (to the extent not reimbursed by the Borrower and without
limiting the obligation of the Borrower to do so), ratably according to its
Commitment Percentage at the time the indemnification request is made, from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following the payment in full of the Borrower Obligations) be imposed on,
incurred by or asserted against the Administrative Agent in its capacity as such
in any way relating to or arising out of this Credit Agreement or the other
Credit Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by the Administrative Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the gross
negligence or willful misconduct of the Administrative Agent. If any indemnity
furnished to the Administrative Agent for any purpose shall, in the opinion of
the Administrative Agent, be insufficient or become impaired, the Administrative
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished. The
agreements in this Section 10.7 shall survive the payment of the Borrower
Obligations and all other amounts payable hereunder and under the other Credit
Documents and the termination of the Commitments.

         10.8 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

         The Administrative Agent and its Affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrower as
though the Administrative Agent were not Administrative Agent hereunder. With
respect to the Loans made and all Borrower Obligations owing to it, the
Administrative Agent shall have the same rights and powers under this Credit
Agreement as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" shall include the
Administrative Agent in its individual capacity.

         10.9 SUCCESSOR AGENT.

         The Administrative Agent may, at any time, resign upon 20 days written
notice to the Lenders. Upon any such resignation, the Required Lenders shall
have the right to appoint a

                                       48
<PAGE>

successor Administrative Agent, which successor shall be reasonably acceptable
to the Borrower; provided that the Borrower shall have no right to approve such
successor during the existence and continuation of a Default or Event of
Default. If no successor Administrative Agent shall have been so appointed by
the Required Lenders, and shall have accepted such appointment, within 30 days
after the notice of resignation, then the retiring Administrative Agent shall
select a successor Administrative Agent; provided such successor is an Eligible
Assignee (or if no Eligible Assignee shall have been so appointed by the
retiring Administrative Agent and shall have accepted such appointment, then the
Lenders shall perform all obligations of the retiring Administrative Agent
hereunder until such time, if any, as a successor Administrative Agent shall
have been appointed and shall have accepted such appointment as provided for
above). Upon the acceptance of any appointment as an Administrative Agent
hereunder by a successor, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations as an Administrative Agent,
as appropriate, under this Credit Agreement and the other Credit Documents and
the provisions of this Section 10 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was an Administrative Agent under
this Credit Agreement.

                                  SECTION 11.

                                  MISCELLANEOUS

         11.1 NOTICES.

         Except as otherwise expressly provided herein, all notices and other
communications shall have been duly given and shall be effective (a) when

reputable national overnight air courier service, or (d) the third Business Day
following the day on which the same is sent by certified or registered mail,
postage prepaid, in each case to the respective parties at the addresses, e-mail
addresses or telecopy numbers set forth on Schedule 11.1, or at such other

Notices and other communications hereunder may be delivered or furnished by
electronic communication (including e-mail and Internet or intranet websites)
pursuant to procedures approved by the Administrative Agent, provided that the
foregoing shall not apply to notices to any Lender pursuant to Section 2 if such
Lender has notified the Administrative Agent that it is incapable of receiving
notices under such Section by electronic communication. The Administrative Agent
or the Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to
procedures approved by it, provided that approval of such procedures may be
limited to particular notices or communications. Unless the Administrative Agent
otherwise prescribes, (i) notices and other communications sent to an e-mail
address shall be deemed received upon the sender's receipt of an acknowledgement
from the intended recipient (such as by the "return receipt requested" function,
as available, return e-mail or other written acknowledgement), provided that if
such notice or other communication is not sent during the normal business hours
of the recipient, such notice or communication shall be deemed to have been sent
at the opening of business on the next business day for the recipient, and (ii)
notices or communications posted to an Internet or intranet website shall be
deemed received upon the deemed receipt by the

                                       49
<PAGE>

intended recipient at its e-mail address as described in the foregoing clause
(i) of notification that such notice or communication is available and
identifying the website address therefor.

         11.2 RIGHT OF SET-OFF.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence and during the continuation of an Event of Default and the
commencement of remedies described in Section 9.2, each Lender is authorized at
any time and from time to time, without presentment, demand, protest or other
notice of any kind (all of which rights being hereby expressly waived), to
set-off and to appropriate and apply any and all deposits (general or special)
and any other indebtedness at any time held or owing by such Lender (including,
without limitation branches, agencies or Affiliates of such Lender wherever
located) to or for the credit or the account of the Borrower against obligations
and liabilities of the Borrower to the Lenders hereunder, under the Notes or the
other Credit Documents, irrespective of whether the Administrative Agent or the
Lenders shall have made any demand hereunder and although such obligations,
liabilities or claims, or any of them, may be contingent or unmatured, and any
such set-off shall be deemed to have been made immediately upon the occurrence
of an Event of Default even though such charge is made or entered on the books
of such Lender subsequent thereto. The Borrower hereby agrees that any Person
purchasing a participation in the Loans and Commitments hereunder pursuant to
Section 11.3(c) may exercise all rights of set-off with respect to its
participation interest as fully as if such Person were a Lender hereunder.

         11.3 BENEFIT OF AGREEMENT.

                  (a) Generally. This Credit Agreement shall be binding upon and
         inure to the benefit of and be enforceable by the respective successors
         and assigns of the parties hereto; provided that the Borrower may not
         assign and transfer any of its interests without the prior written
         consent of the Lenders; and provided further that the rights of each
         Lender to transfer, assign or grant participations in its rights and/or
         obligations hereunder shall be limited as set forth below in this
         Section 11.3.

                  (b) Assignments. Each Lender may assign to one or more
         Eligible Assignees all or a portion of its rights and obligations under
         this Credit Agreement (including, without limitation, all or a portion
         of its Loans, its Notes, and its Commitment); provided, however, that:

                           (i) each such assignment shall be to an Eligible
                  Assignee;

                           (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's rights and
                  obligations under this Credit Agreement, any such partial
                  assignment shall (unless each of the Borrower and the
                  Administrative Agent otherwise consents) be in an amount at
                  least equal to $3,000,000 (or, if less, the remaining amount
                  of the Commitment being assigned by such Lender) and an
                  integral multiple of $1,000,000 in excess thereof;

                                       50
<PAGE>

                           (iii) each such assignment by a Lender shall be of a
                  constant, and not varying, percentage of all of its rights and
                  obligations under this Credit Agreement and the Notes; and

                           (iv) the parties to such assignment shall execute and
                  deliver to the Administrative Agent for its acceptance an
                  Assignment Agreement in substantially the form of Exhibit
                  11.3(b), together with a processing fee from the assignor of
                  $5,000.

         Upon execution, delivery, and acceptance of such Assignment Agreement,
         the assignee thereunder shall be a party hereto and, to the extent of
         such assignment, have the obligations, rights, and benefits of a Lender
         hereunder and the assigning Lender shall, to the extent of such
         assignment, relinquish its rights and be released from its obligations
         under this Credit Agreement. Upon the consummation of any assignment
         pursuant to this Section 11.3(b), the assignor, the Administrative
         Agent and the Borrower shall make appropriate arrangements so that, if
         required, new Notes are issued to the assignor and the assignee. If the
         assignee is not incorporated under the laws of the United States of
         America or a state thereof; it shall deliver to the Borrower and the
         Administrative Agent certification as to exemption from deduction or
         withholding of taxes in accordance with Section 4.4.

                  By executing and delivering an assignment agreement in
         accordance with this Section 11.3(b), the assigning Lender thereunder
         and the assignee thereunder shall be deemed to confirm to and agree
         with each other and the other parties hereto as follows: (A) such
         assigning Lender warrants that it is the legal and beneficial owner of
         the interest being assigned thereby free and clear of any adverse claim
         created by such assigning Lender and the assignee warrants that it is
         an Eligible Assignee; (B) except as set forth in clause (A) above, 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 Credit Agreement,
         any of the other Credit Documents or any other instrument or document
         furnished pursuant hereto or thereto, or the execution, legality,
         validity, enforceability, genuineness, sufficiency or value of this
         Credit Agreement, any of the other Credit Documents or any other
         instrument or document furnished pursuant hereto or thereto or the
         financial condition of the Borrower or the performance or observance by
         the Borrower of any of its obligations under this Credit Agreement, any
         of the other Credit Documents or any other instrument or document
         furnished pursuant hereto or thereto; (C) such assignee represents and
         warrants that it is legally authorized to enter into such assignment
         agreement; (D) such assignee confirms that it has received a copy of
         this Credit Agreement, the other Credit Documents and such other
         documents and information as it has deemed appropriate to make its own
         credit analysis and decision to enter into such assignment agreement;
         (E) such assignee will independently and without reliance upon the
         Administrative 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 Credit Agreement and the other Credit
         Documents; (F) such assignee appoints and authorizes the Administrative
         Agent to take such action on its behalf and to exercise such powers
         under this Credit Agreement or any

                                       51
<PAGE>

         other Credit Document as are delegated to the Administrative Agent by
         the terms hereof or thereof, together with such powers as are
         reasonably incidental thereto; and (G) such assignee agrees that it
         will perform in accordance with their terms all the obligations which
         by the terms of this Credit Agreement and the other Credit Documents
         are required to be performed by it as a Lender.

                  (c) Register. The Administrative Agent, acting for these
         purposes as agent for the Borrower, shall maintain a copy of each
         Assignment Agreement delivered to and accepted by it and a register for
         the recordation of the names and addresses of the Lenders and the
         Commitment of, and principal amount of the Loans owing to, each Lender
         from time to time (the "Register"). The entries in the Register shall
         be conclusive and binding for all purposes, absent manifest error, and
         the Borrower, the Administrative Agent and the Lenders may treat each
         Person whose name is recorded in the Register as a Lender hereunder for
         all purposes of this Credit Agreement. The Register shall be available
         for inspection by the Borrower or any Lender at any reasonable time and
         from time to time upon reasonable prior notice.

                  (d) Acceptance. Upon its receipt of an Assignment Agreement
         executed by the parties thereto, together with any Note subject to such
         assignment and payment of the processing fee, the Administrative Agent
         shall, if such Assignment Agreement has been completed and is in
         substantially the form of Exhibit 11.3(b), (i) accept such Assignment
         Agreement, (ii) record the information contained therein in the
         Register and (iii) give prompt notice thereof to the parties thereto.

                  (e) Participations. Each Lender may sell participations to one
         or more Persons in all or a portion of its rights, obligations or
         rights and obligations under this Credit Agreement (including all or a
         portion of its Commitment, its Notes and its Loans); provided, however,
         that (i) such Lender's obligations under this Credit Agreement shall
         remain unchanged, (ii) such Lender shall remain solely responsible to
         the other parties hereto for the performance of such obligations, (iii)
         the participant shall be entitled to the benefit of the yield
         protection provisions contained in Sections 4.1 through 4.4, inclusive,
         except that such participant shall not be entitled to receive any
         greater payment under Sections 4.1 through 4.4, inclusive, than the
         applicable Lender would have been entitled to receive with respect to
         the participation sold to such participant, unless the sale of the
         participation to such participant is made with the Borrower's prior
         written consent; and (iv) the Borrower shall continue to deal solely
         and directly with such Lender in connection with such Lender's rights
         and obligations under this Credit Agreement, and such Lender shall
         retain the sole right to enforce the obligations of the Borrower
         relating to its Loans and its Notes and to approve any amendment,
         modification, or waiver of any provision of this Credit Agreement
         (other than amendments, modifications, or waivers decreasing the amount
         of principal of or the rate at which interest is payable on such Loans
         or Notes, extending any scheduled principal payment date or date fixed
         for the payment of interest on such Loans or Notes, or extending its
         Commitment).

                  (f) Nonrestricted Assignments. Notwithstanding any other
         provision set forth in this Credit Agreement, any Lender may at any
         time assign and pledge all or any portion of its Loans and its Notes to
         any Federal Reserve Bank as collateral security

                                       52
<PAGE>

         pursuant to Regulation A and any Operating Circular issued by such
         Federal Reserve Bank. No such assignment shall release the assigning
         Lender from its obligations hereunder.

                  (g) Information. Subject to Section 11.8, any Lender may
         furnish any information concerning the Borrower in the possession of
         such Lender from time to time to assignees and participants (including
         prospective assignees and participants).

         11.4 NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Borrower and the
Administrative Agent or any Lender shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, power or privilege hereunder or
under any other Credit Document preclude any other or further exercise thereof
or the exercise of any other right, power or privilege hereunder or thereunder.
The rights and remedies provided herein are cumulative and not exclusive of any
rights or remedies which the Administrative Agent or any Lender would otherwise
have. No notice to or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Administrative Agent
or the Lenders to any other or further action in any circumstances without
notice or demand.

         11.5 PAYMENT OF EXPENSES, ETC.

         The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and
expenses of the Administrative Agent and the Arrangers in connection with (A)
the negotiation, preparation, execution and delivery and administration of this
Credit Agreement and the other Credit Documents and the documents and
instruments referred to therein (including, without limitation, the reasonable
fees and expenses of Mayer, Brown, Rowe & Maw LLP, special counsel to the
Administrative Agent) and (B) any amendment, waiver or consent relating hereto
and thereto including, but not limited to, any such amendments, waivers or
consents resulting from or related to any work-out, renegotiation or restructure
relating to the performance by the Borrower under this Credit Agreement, (ii)
pay all reasonable out-of-pocket costs and expenses of the Administrative Agent
and the Lenders in connection with (A) enforcement of the Credit Documents and
the documents and instruments referred to therein (including, without
limitation, in connection with any such enforcement, the reasonable fees and
disbursements of counsel for the Administrative Agent and each of the Lenders
(including the allocated cost of internal counsel)) and (B) any bankruptcy or
insolvency proceeding of the Borrower and (iii) indemnify the Administrative
Agent, each Arranger and each Lender, its officers, directors, employees,
representatives and agents from and hold each of them harmless against any and
all losses, liabilities, claims, damages or expenses incurred by any of them as
a result of, or arising out of, or in any way related to, or by reason of, any
investigation, litigation or other proceeding (whether or not the Administrative
Agent, any Arranger or any Lender is a party thereto) related to the entering
into and/or performance of any Credit Document or the use of proceeds of any
Loans (including other extensions of credit) hereunder or the consummation of
any other transactions contemplated in any Credit Document, including, without
limitation, the reasonable fees and disbursements of counsel (including the
allocated cost of internal counsel) incurred in

                                       53
<PAGE>

connection with any such investigation, litigation or other proceeding (but
excluding any such losses, liabilities, claims, damages or expenses to the
extent incurred by reason of gross negligence or willful misconduct on the part
of the Person to be indemnified).

         11.6 AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement, nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing and signed by the Required Lenders and the Borrower; provided that no
such amendment, change, waiver, discharge or termination shall without the
consent of each Lender affected thereby:

                  (a) extend the Maturity Date, or postpone or extend the time
         for any payment or prepayment of principal;

                  (b) reduce the rate or amount or extend the time of payment of
         interest (other than as a result of waiving the applicability of any
         post-default increase in interest rates) thereon or fees or other
         amounts payable hereunder;

                  (c) reduce or waive the principal amount of any Loan;

                  (d) increase or extend the Commitment of a Lender (it being
         understood and agreed that a waiver of any Default or Event of Default
         or a waiver of any mandatory reduction in the Commitments shall not
         constitute a change in the terms of any Commitment of any Lender);

                  (e) release the Borrower from its obligations under the Credit
         Documents;

                  (f) amend, modify or waive any provision of this Section 11.6
         or Section 3.6, 3.8, 9.1(a) or 11.2;

                  (g) reduce any percentage specified in, or otherwise modify,
         the definition of Required Lenders; or

                  (h) consent to the assignment or transfer by the Borrower of
         any of its rights and obligations under (or in respect of) the Credit
         Documents.

No provision of Section 10 may be amended or modified without the consent of the
Administrative Agent.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans, and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code supersedes the unanimous consent provisions set forth herein.

                                       54

         11.7 COUNTERPARTS/TELECOPY.

         This Credit Agreement may be executed in any number of counterparts,
each of which where so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. Delivery of executed
counterparts by telecopy shall be as effective as an original and shall
constitute a representation that an original will be delivered.

         11.8 CONFIDENTIALITY.

         Each of the Administrative Agent and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential), (b) to the extent requested by any regulatory
authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Credit
Agreement, (e) in connection with the exercise of any remedies hereunder or any
suit, action or proceeding relating to this Credit Agreement or the enforcement
of rights hereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Credit Agreement or (ii) any actual or
prospective counterparty (or its advisors) to any swap or derivative transaction
relating to the Borrower and its obligations, (g) with the consent of the
Borrower or (h) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section or (ii) becomes available to
the Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, "Information" means
all information received from the Borrower relating to the Borrower or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received
from the Borrower after the date hereof, such information is clearly identified
at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

         11.9 HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

         11.10 DEFAULTING LENDER.

         Each Lender understands and agrees that if such Lender is a Defaulting
Lender then it shall not be entitled to vote on any matter requiring the consent
of the Required Lenders or to object to any matter requiring the consent of all
the Lenders; provided, however, that all other benefits and obligations under
the Loan Documents shall apply to such Defaulting Lender.

         11.11 SURVIVAL OF INDEMNIFICATION AND REPRESENTATIONS AND WARRANTIES.

         All indemnities set forth herein and all representations and warranties
made herein shall survive the execution and delivery of this Credit Agreement,
the making of the Loans, and the repayment of the Loans and other obligations
and the termination of the Commitments hereunder.

         11.12 GOVERNING LAW; VENUE.

                  (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND
         THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER
         SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH
         THE LAWS OF THE STATE OF NEW YORK.

                  (b) Any legal action or proceeding with respect to this Credit
         Agreement or any other Credit Document may be brought in the courts of
         the State of New York or of the United States for the Southern District
         of New York, and, by execution and delivery of this Credit Agreement,
         the Borrower hereby irrevocably accepts for itself and in respect of
         its property, generally and unconditionally, the jurisdiction of such
         courts. The Borrower further irrevocably consents to the service of
         process out of any of the aforementioned courts in any such action or
         proceeding by the mailing of copies thereof by registered or certified
         mail, postage prepaid, to it at the address for notices pursuant to
         Section 11.1, such service to become effective 10 days after such
         mailing. Nothing herein shall affect the right of a Lender to serve
         process in any other manner permitted by law or to commence legal
         proceedings or to otherwise proceed against the Borrower in any other
         jurisdiction. The Borrower agrees that a final judgment in any action
         or proceeding shall be conclusive and may be enforced in other
         jurisdictions by suit on the judgment or in any other manner provided
         by law; provided that nothing in this Section 11.12(b) is intended to
         impair the Borrower's right under applicable law to appeal or seek a
         stay of any judgment.

                  (c) The Borrower hereby irrevocably waives any objection which
         it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Credit Agreement or any other Credit Document in the courts
         referred to in subsection (a) hereof and hereby further irrevocably
         waives and agrees not to plead or claim in any such court that any such
         action or proceeding brought in any such court has been brought in an
         inconvenient forum.

         11.13 WAIVER OF JURY TRIAL.

         EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

         11.14 SEVERABILITY.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         11.15 FURTHER ASSURANCES.

         The Borrower agrees, upon the request of the Administrative Agent, to
promptly take such actions, as reasonably requested, as are necessary to carry
out the intent of this Credit Agreement and the other Credit Documents.

         11.16 ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede
all prior agreements and understandings, oral or written, if any, including any
commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.

         11.17 BINDING EFFECT; CONTINUING AGREEMENT.

                  (a) This Credit Agreement shall become effective at such time
         when all of the conditions set forth in Section 5.1 have been satisfied
         or waived by the Lenders and it shall have been executed by the
         Borrower, the Administrative Agent and the Lenders, and thereafter this
         Credit Agreement shall be binding upon and inure to the benefit of the
         Borrower, the Administrative Agent and each Lender and their respective
         successors and assigns. The Borrower and the Lenders party to the
         Existing Credit Agreement each hereby agrees that, at such time as this
         Credit Agreement shall have become effective pursuant to the terms of
         the immediately preceding sentence, the Existing Credit Agreement
         automatically shall be deemed terminated and the Borrowers and the
         Lenders party to the Existing Credit Agreement shall no longer have any
         obligations thereunder (other than those obligations in the Existing
         Credit Agreement that expressly survive the termination thereof).

                  (b) This Credit Agreement shall be a continuing agreement and
         shall remain in full force and effect until all Loans, interest, fees
         and other Borrower Obligations have been paid in full and all
         Commitments have been terminated. Upon termination, the Borrower shall
         have no further obligations (other than the indemnification provisions
         that survive) under the Credit Documents; provided that should any
         payment, in whole or in part, of the Borrower Obligations be rescinded
         or otherwise required to be restored or returned by the Administrative
         Agent or any Lender, whether as a result of any proceedings in
         bankruptcy or reorganization or otherwise, then the Credit Documents
         shall automatically be reinstated and all amounts required to be
         restored or returned and all costs and expenses incurred by the
         Administrative Agent or any Lender in connection therewith shall be
         deemed included as part of the Borrower Obligations.

         11.18 USA PATRIOT ACT.

         Each Lender that is subject to the requirements of the USA Patriot Act
(Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the "Act")
hereby notifies the Borrower that pursuant to the requirements of the Act, it is

which information includes the name and address of the Borrower and other
information that will allow such Lender to identify the Borrower in accordance
with the Act.
