                  "ABR Loan" shall mean any Loan bearing interest at a rate

         the provisions of Article II or any Eurodollar Loan converted (pursuant
         to Section 2.08 or 2.12(a)(ii)) to a loan bearing interest at a rate

                                                                              2

                  "Agreement" shall have the meaning given such term in the
         preamble hereto.

                  "Alternate Base Rate" shall mean, for any day, a rate per
         annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to
         the greater of (i) the Federal Funds Effective Rate in effect on such
         day plus 0.50% and (ii) the Prime Rate in effect on such day. For
         purposes hereof, "Prime Rate" shall mean the rate of interest per annum
         publicly announced from time to time by JPMorgan Chase as its prime
         rate in effect at its principal office in New York City; each change in
         the Prime Rate shall be effective on the date such change is publicly
         announced as effective; and "Federal Funds Effective Rate" shall mean,
         for any day, the weighted average of the rates on overnight Federal
         funds transactions with members of the Federal Reserve System arranged
         by Federal funds brokers, as released on the next succeeding Business
         Day by the Federal Reserve Bank of New York, or, if such rate is not so
         released for any day which is a Business Day, the arithmetic average
         (rounded upwards to the next 1/100th of 1%), as determined by JPMorgan
         Chase, of the quotations for the day of such transactions received by
         JPMorgan Chase from three Federal funds brokers of recognized standing
         selected by it. If for any reason JPMorgan Chase shall have determined
         (which determination shall be conclusive absent manifest error;
         provided that JPMorgan Chase shall, upon request, provide to the
         applicable Borrower a certificate setting forth in reasonable detail
         the basis for such determination) that it is unable to ascertain the
         Federal Funds Effective Rate for any reason, including the inability of
         JPMorgan Chase to obtain sufficient quotations in accordance with the
         terms thereof, the Alternate Base Rate shall be determined without
         regard to clause (i) of the first sentence of this definition until the
         circumstances giving rise to such inability no longer exist. Any change
         in the Alternate Base Rate due to a change in the Prime Rate or the
         Federal Funds Effective Rate shall be effective on the effective date
         of such change in the Prime Rate or the Federal Funds Effective Rate,
         respectively.

                  "Applicable Margin" shall mean, with respect to any Borrower
         for any Type of Loan at any time, the percentage per annum set forth
         below corresponding to such Type of Loan in the column under the
         Applicable Rating Level of such Borrower at such time, provided that
         (i) during any Utilization Period, the Applicable Margin for each
         Borrower for each Type of Loan shall be increased by the Utilization
         Percentage and (ii) after the Revolving Period, the Applicable Margin
         shall be increased by the percentage per annum set forth below
         corresponding to "Term Loan Margin" in the column under the Applicable
         Rating Level for such Borrower. Any change in the Applicable Margin for
         a Borrower shall be effective on the date on which the applicable
         rating agency announces any change in the Debt Rating of such Borrower.

         time, the level set forth below in the row next to the then applicable
         Debt Ratings of such Borrower. If there is a difference of one level in
         the Debt Ratings of such Borrower assigned by S&P and Moody's, then the
         higher Debt Rating shall be used for purposes of determining the
         Applicable Rating Level for such Borrower and if there is a difference
         of more than one level in the Debt Ratings assigned by S&P and Moody's
         for such Borrower, then the Debt Rating one level higher than the lower

require, any pronoun shall include the corresponding masculine, feminine and

Articles, Sections, Exhibits and Schedules shall be deemed references to
Articles and Sections of, and Exhibits and Schedules to, this Agreement unless
the context shall otherwise require. Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in
accordance with GAAP, as in effect from time to time; provided, however, that
for purposes of determining compliance with any covenant set forth in Article V,
such terms shall be construed in accordance with GAAP as in effect on the date
hereof applied on a basis consistent with the application used in preparing the
Borrowers' audited financial statements referred to in Section 3.05.

                                  ARTICLE II
                                 THE CREDITS

         SECTION 2.01.     Commitments.

         Subject to the terms and conditions and relying upon the
representations and warranties herein set forth, each Lender agrees, severally
and not jointly, to make Loans to any Borrower at any time and from time to time
until the last day of the Revolving Period or the prior termination of the
Commitment of such Lender up to the amount of such Lender's Available
Commitment, each Fronting Bank agrees to issue Letters of Credit for the account
of any Borrower at any time and from time to time until the fifth Business Day
preceding the last day of the Revolving Period in an aggregate stated amount at
any time outstanding not to exceed such Fronting Bank's LC Fronting Bank
Commitment, and each Lender agrees to purchase participations in such Letters of
Credit as more fully set forth in Section 2.19, subject, however, to the
conditions that (i) at no time shall Outstanding Credits exceed the Total
Commitment, (ii) at no time shall any Lender's Outstanding Credits exceed the
amount of such Lender's Commitment, (iii) at no time shall the

<PAGE>

                                                                              17

Outstanding Credits available to any Borrower exceed the Total Commitment, and
(iv) at no time shall any Fronting Bank make any Extension of Credit relating to
a Letter of Credit if such Extension of Credit would cause the aggregate amount
of Outstanding Credits to exceed the Total Commitment or the aggregate LC
Outstandings relating to such Fronting Bank to exceed such Fronting Bank's LC
Fronting Bank Commitment.

         Within the foregoing limits, the Borrowers may borrow, pay or prepay
Loans and request new Extensions of Credit hereunder, on and after the date
hereof and prior to the Maturity Date subject to the terms, conditions and
limitations set forth herein.

         SECTION 2.02.     Loans.

         (a)     Each Loan shall be made as part of a Borrowing consisting of
Loans made by the Lenders ratably in accordance with their respective
Commitments; provided, however, that the failure of any Lender to make any Loan
shall not in itself relieve any other Lender of its obligation to lend hereunder
(it being understood, however, that no Lender shall be responsible for the
failure of any other Lender to make any Loan required to be made by such other
Lender). The Loans comprising any Borrowing shall be in an aggregate principal
amount that is an integral multiple of $5,000,000 and not less than $25,000,000
(or an aggregate principal amount equal to the remaining balance of the
Available Commitments).

         (b)     Each Borrowing shall be comprised entirely of Eurodollar Loans
or ABR Loans, as the applicable Borrower may request pursuant to Section 2.03.
Each Lender may at its option make any Eurodollar Loan by causing any domestic
or foreign branch or Affiliate of such Lender to make such Loan; provided that
any exercise of such option shall not affect the obligation of any Borrower to
repay such Loan in accordance with the terms of this Agreement. Borrowings of
more than one Type may be outstanding at the same time.

         (c)     Subject to paragraph (d) below, each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Agent in New York, New York, not later than
noon, New York City time, and the Agent shall by 2:00 p.m., New York City time,
credit the amounts so received to the account or accounts specified from time to
time in one or more notices delivered by the applicable Borrower to the Agent
or, if a Borrowing shall not occur on such date because any condition precedent
herein specified shall not have been met, return the amounts so received to the
respective Lenders. Loans shall be made by the Lenders pro rata in accordance
with Section 2.13. Unless the Agent shall have received notice from a Lender
prior to the date of any Borrowing that such Lender will not make available to
the Agent such Lender's portion of such Borrowing, the Agent may assume that
such Lender has made such portion available to the Agent on the date of such
Borrowing in accordance with this paragraph (c) and the Agent may, in reliance
upon such assumption, make available to the applicable Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have made
such portion available to the Agent, such Lender and the applicable Borrower
(without waiving any claim against such Lender for such Lender's failure to make
such portion available) severally agree to repay to the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to such Borrower until the date such
amount is repaid to the Agent, at (i) in the case of such Borrower, the interest
rate applicable at the time to the Loans

<PAGE>

                                                                              18

comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds
Effective Rate. If such Lender shall repay to the Agent such corresponding
amount, such amount shall constitute such Lender's Loan as part of such
Borrowing for purposes of this Agreement.

         (d)     A Borrower may refinance all or any part of any Borrowing with
a Borrowing of the same or a different Type, subject to the conditions and
limitations set forth in this Agreement. Any Borrowing or part thereof so
refinanced shall be deemed to be repaid or prepaid in accordance with Section
2.05 or 2.10, as applicable, with the proceeds of a new Borrowing, and the
proceeds of the new Borrowing, to the extent they do not exceed the principal
amount of the Borrowing being refinanced, shall not be paid by the Lenders to
the Agent or by the Agent to such Borrower pursuant to paragraph (c) above.

         SECTION 2.03.     Borrowing Procedure.

         In order to request a Borrowing, a Borrower shall hand deliver or
telecopy to the Agent a duly completed Borrowing Request in the form of Exhibit
A (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York
City time, three Business Days before such Borrowing, and (b) in the case of an
ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day
before such Borrowing. Such notice shall be irrevocable and shall in each case
specify (i) whether the Borrowing then being requested is to be a Eurodollar
Borrowing or an ABR Borrowing; (ii) the date of such Borrowing (which shall be a
Business Day) and the amount thereof; and (iii) if such Borrowing is to be a
Eurodollar Borrowing, the Interest Period with respect thereto, which shall not
end after the Maturity Date. If no election as to the Type of Borrowing is
specified in any such notice, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is
specified in any such notice, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration (subject to the limitations set forth
in the definition of "Interest Period"). If a Borrower shall not have given
notice in accordance with this Section 2.03 of its election to refinance a
Borrowing prior to the end of the Interest Period in effect for such Borrowing,
then such Borrower shall (unless such Borrowing is repaid at the end of such
Interest Period) be deemed to have given notice of an election to refinance such
Borrowing with an ABR Borrowing. Notwithstanding any other provision of this
Agreement to the contrary, no Borrowing shall be requested if the Interest
Period with respect thereto would end after the Maturity Date. The Agent shall
promptly advise the Lenders of any notice given pursuant to this Section 2.03
and of each Lender's portion of the requested Borrowing.

         SECTION 2.04.     Fees.

         (a)     Holdings agrees to pay to each Lender, through the Agent, on
each March 31, June 30, September 30 and December 31 (with the first payment
being due on June 30, 2002) and on each date on which the Commitment of such
Lender shall be terminated or reduced as provided herein, a facility fee (a
"Facility Fee"), at a rate per annum equal to the Facility Fee Percentage from
time to time in effect on the amount of the Commitment of such Lender (whether
used or unused), during the preceding quarter (or other period commencing on the
date of this Agreement or ending on the Maturity Date or any date on which the
Commitment of such Lender shall be terminated). All Facility Fees shall be
computed on the basis of the actual number of days elapsed in a year of 360
days. The Facility Fee due to each Lender shall

                                                                              19

commence to accrue on the date of this Agreement, and shall cease to accrue on
the date of termination of the Commitment of such Lender as provided herein.

         (b)     Holdings agrees to pay the Agent the fees from time to time
payable to it in its capacity as Agent pursuant to the Letter Agreements (the
"Administrative Fee").

         (c)     Each Borrower for the account of which a Letter of Credit is
issued agrees to pay the Agent for the account of the Fronting Bank that issued
such Letter of Credit a fronting fee (a "Fronting Fee") and such other charges
with respect to such Letter of Credit as are set forth in the Letter Agreements
or otherwise agreed upon with such Fronting Bank, and agrees to pay to the Agent
for the account of the Lenders a fee (the "LC Fee") on the face amount of each
Letter of Credit issued by any Fronting Bank for the account of such Borrower
calculated at a rate per annum equal to the Applicable Margin for Eurodollar
Loans (whether any such Loans are then outstanding), computed on the basis of
the actual number of days that each such Letter of Credit is outstanding,
assuming a year of 360 days, payable in arrears on each March 31, June 30,
September 30 and December 31, and on the date that such Letter of Credit expires
or is drawn in full.

         (d)     All Fees shall be paid on the dates due, in immediately
available funds, to the Agent for distribution, if and as appropriate, among the
Lenders. Once paid, none of the Fees shall be refundable under any
circumstances.

         SECTION 2.05.     Repayment of Loans; Evidence of Indebtedness.

         (a)     The outstanding principal balance of each Loan shall be due and
payable on the last day of the Interest Period applicable thereto and on the
Maturity Date.

         (b)     Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing the indebtedness to such Lender
resulting from each Extension of Credit made by such Lender from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time under this Agreement.

         (c)     The Agent shall maintain accounts in which it will record (i)
the amount of each Extension of Credit made hereunder, the Type of each Loan
made and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from each
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Agent hereunder from each Borrower and each Lender's share thereof.

         (d)     The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) of this Section 2.05 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Agent to maintain such accounts or any error therein shall not in any
manner affect the obligations of the Borrowers to repay the Outstanding Credits
in accordance with their terms.

                                                                              20

         SECTION 2.06.     Interest on Loans.

         (a)     Subject to the provisions of Section 2.07, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to the LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Margin from time to time in effect.

         (b)     Subject to the provisions of Section 2.07, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of (i) 365 or 366 days, as the case may be,
for periods during which the Alternate Base Rate is determined by reference to
the Prime Rate and (ii) 360 days for other periods) at a rate per annum equal to
the Alternate Base Rate plus the Applicable Margin from time to time in effect.

         (c)     Interest on each Loan shall be payable on each Interest Payment
Date applicable to such Loan except as otherwise provided in this Agreement. The
applicable LIBO Rate or Alternate Base Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by JPMorgan
Chase, and such determination shall be conclusive absent manifest error;
provided that JPMorgan Chase shall, upon request, provide to the applicable
Borrower a certificate setting forth in reasonable detail the basis for such
determination.

         SECTION 2.07.     Default Interest.

         If a Borrower shall default in the payment of the principal of or
interest on any Loan or any other amount becoming due hereunder, whether by
scheduled maturity, notice of prepayment, acceleration or otherwise, such
Borrower shall on demand from time to time from the Agent pay interest, to the
extent permitted by law, on such defaulted amount up to (but not including) the
date of actual payment (after as well as before judgment) at a rate per annum
(computed as provided in Section 2.06(b)) equal to the Alternate Base Rate plus
the Applicable Margin for ABR Loans plus 2%.

         SECTION 2.08.     Alternate Rate of Interest.

         In the event, and on each occasion, that on the day two Business Days
prior to the commencement of any Interest Period for a Eurodollar Borrowing the
Agent shall have determined (i) that dollar deposits in the principal amounts of
the Eurodollar Loans comprising such Borrowing are not generally available in
the London interbank market or (ii) that reasonable means do not exist for
ascertaining the LIBO Rate, the Agent shall, as soon as practicable thereafter,
give telecopy notice of such determination to the Borrowers and the Lenders. In
the event of any such determination under clause (i) or (ii) above, until the
Agent shall have advised the Borrowers and the Lenders that the circumstances
giving rise to such notice no longer exist, any request by a Borrower for a
Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request
for an ABR Borrowing. In the event the Required Lenders notify the Agent that
the rates at which dollar deposits are being offered will not adequately and
fairly reflect the cost to such Lenders of making or maintaining Eurodollar
Loans during such Interest Period, the Agent shall notify the applicable
Borrower of such notice and until the Required Lenders shall have advised the
Agent that the circumstances giving rise to such notice no longer exist, any
request by such Borrower for a Eurodollar Borrowing shall be deemed a request

Borrowing. Each determination by the Agent hereunder shall be made in good faith
and shall be conclusive absent manifest error; provided that the Agent, shall,
upon request, provide to the applicable Borrower a certificate setting forth in
reasonable detail the basis for such determination.

         SECTION 2.09.     Termination and Reduction of Commitments.

         (a) The Commitments shall be automatically terminated on the Maturity
Date.

         (b) On the last day of the Revolving Period, the Total Commitment shall
be permanently reduced to an amount equal to the Outstanding Credits. In
addition, if on any date following the last day of the Revolving Period the
Outstanding Credits shall be less than the Total Commitment, then on such date
the Total Commitment shall be permanently reduced to an amount equal to the then
Outstanding Credits.

         (c) Upon at least two Business Days' prior irrevocable written notice
to the Agent, the Borrowers, acting jointly, may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the
Total Commitment; provided, however, that (i) each partial reduction of the
Total Commitment shall be in an integral multiple of $10,000,000 and in a
minimum principal amount of $10,000,000 and (ii) no such termination or
reduction shall be made that would reduce the Total Commitment to an amount less
than (1) the aggregate amount of Outstanding Credits on the date of such
termination or reduction (after giving effect to any prepayment made pursuant to
Section 2.10) or (2) $50,000,000, unless the result of such termination or
reduction referred to in this clause (2) is to reduce the Total Commitment to
$0. The Agent shall advise the Lenders of any notice given pursuant to this
Section 2.09(c) and of each Lender's portion of any such termination or
reduction of the Total Commitment.

         (d) Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments. The
Borrowers shall pay to the Agent for the account of the Lenders, on the date of
each termination or reduction of the Total Commitment, the Facility Fees on the
amount of the Commitments so terminated or reduced accrued through the date of
such termination or reduction.

         SECTION 2.10.     Prepayment.

         (a) Each Borrower shall have the right at any time and from time to
time to prepay any Borrowing, in whole or in part, upon giving telecopy notice
(or telephone notice promptly confirmed by telecopy) to the Agent: (i) before
11:00 a.m., New York City time, three Business Days prior to prepayment, in the
case of Eurodollar Loans, and (ii) before 11:00 a.m., New York City time, one
Business Day prior to prepayment, in the case of ABR Loans; provided, however,
that each partial prepayment shall be in an amount which is an integral multiple
of $10,000,000 and not less than $10,000,000. Any principal amount of any Loan
repaid or prepaid on or after the last day of the Revolving Period and not
refinanced with the proceeds of another Loan on the date of such repayment or
prepayment (as the case may be) may not be reborrowed.

         (b) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid, shall be
irrevocable and shall commit the Borrower to prepay such Borrowing (or portion
thereof) by the amount stated therein

<PAGE>

                                                                              22

on the date stated therein. All prepayments under this Section 2.10 shall be
subject to Section 8.05 but otherwise without premium or penalty. All
prepayments under this Section 2.10 shall be accompanied by accrued interest on
the principal amount being prepaid to the date of payment.

         SECTION 2.11.     Reserve Requirements; Change in Circumstances.

         (a) Notwithstanding any other provision herein, if after the date of
this Agreement any change in applicable law or regulation or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to any Lender or
any Fronting Bank hereunder (except for changes in respect of taxes on the
overall net income of such Lender or such Fronting Bank (as the case may be) or
its lending office imposed by the jurisdiction in which such Lender's or such
Fronting Bank's (as the case may be) principal executive office or lending
office is located), or shall result in the imposition, modification or
applicability of any reserve, special deposit or similar requirement against
assets of, deposits with or for the account of or credit extended by any Lender
or such Fronting Bank (as the case may be) or shall result in the imposition on
any Lender, any Fronting Bank or the London interbank market of any other
condition affecting this Agreement, such Lender's Commitment or any Extension of
Credit (other than an ABR Loan) made by such Lender or such Fronting Bank, and
the result of any of the foregoing shall be to increase the cost to such Lender
or such Fronting Bank (as the case may be) of making or maintaining any
Outstanding Credit (other than an ABR Loan) or to reduce the amount of any sum
received or receivable by such Lender or such Fronting Bank (as the case may be)
hereunder (whether of principal, interest or otherwise) by an amount deemed by
such Lender or such Fronting Bank (as the case may be) to be material, then the
applicable Borrower or, if the foregoing circumstances do not relate to a
particular Borrowing, Holdings shall, upon receipt of the notice and certificate
provided for in Section 2.11(c), promptly pay to such Lender or such Fronting
Bank (as the case may be) such additional amount or amounts as will compensate
such Lender or such Fronting Bank (as the case may be) for such additional costs
incurred or reduction suffered.

         (b) If any Lender or Fronting Bank shall have determined that the
adoption of any law, rule, regulation or guideline arising out of the July 1988
report of the Basle Committee on Banking Regulations and Supervisory Practices
entitled "International Convergence of Capital Measurement and Capital
Standards," or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
Fronting Bank (or any lending office of such Lender or such Fronting Bank) or
any Lender's or any Fronting Bank's holding company 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 such

<PAGE>

                                                                              23

Fronting Bank's (as the case may be) capital or on the capital of such Lender's
or such Fronting Bank's (as the case may be) holding company, if any, as a
consequence of this Agreement, such Lender's Commitment or the Extensions of
Credit made by such Lender or such Fronting Bank (as the case may be) pursuant
hereto to a level below that which such Lender or such Fronting Bank (as the
case may be) or such Lender's or such Fronting Bank's (as the case may be)
holding company could have achieved but for such adoption, change or compliance
(taking into consideration such Lender's or such Fronting Bank's (as the case
may be) policies and the policies of such Lender's or such Fronting Bank's (as
the case may be) holding company with respect to capital adequacy) by an amount
deemed by such Lender or such Fronting Bank (as the case may be) to be material,
then from time to time such additional amount or amounts as will compensate such
Lender or such Fronting Bank (as the case may be) for any such reduction
suffered will be paid to such Lender or such Fronting Bank (as the case may be)
by the applicable Borrower or, if the foregoing circumstances do not relate to a
particular Borrower, by Holdings. It is acknowledged that this Agreement is
being entered into by the Lenders and the Fronting Banks on the understanding
that neither the Lenders nor the Fronting Banks will be required to maintain
capital against their Commitments or agreements to issue Letters of Credit, as
the case may be, under currently applicable laws, regulations and regulatory
guidelines. In the event the Lenders or any Fronting Bank shall otherwise
determine that such understanding is incorrect, it is agreed that the Lenders or
the Fronting Banks, as the case may be, will be entitled to make claims under
this paragraph (b) based upon market requirements prevailing on the date hereof
for commitments under comparable credit facilities against which capital is
required to be maintained.

         (c) A certificate of each Lender or the applicable Fronting Bank
setting forth such amount or amounts as shall be necessary to compensate such
Lender or such Fronting Bank (as the case may be) or its holding company as
specified in paragraph (a) or (b) above, as the case may be, and containing an
explanation in reasonable detail of the manner in which such amount or amounts
shall have been determined, shall be delivered to the applicable Borrower or the
Borrowers, as the case may be, and shall be conclusive absent manifest error.
The applicable Borrower shall pay each Lender or Fronting Bank (as the case may
be) the amount shown as due on any such certificate delivered by it within 10
days after its receipt of the same. Each Lender and each Fronting Bank shall
give prompt notice to the applicable Borrower of any event of which it has
knowledge, occurring after the date hereof, that it has determined will require
compensation by such Borrower pursuant to this Section; provided, however, that
failure by such Lender or such Fronting Bank to give such notice shall not
constitute a waiver of such Lender's or such Fronting Bank's (as the case may
be) right to demand compensation hereunder.

         (d) Failure on the part of any Lender or Fronting Bank to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital with respect to any period shall
not constitute a waiver of such Lender's or such Fronting Bank's (as the case
may be) right to demand compensation with respect to such period or any other
period; provided, however, that no Lender or Fronting Bank shall be entitled to
compensation under this Section 2.11 for any costs incurred or reductions
suffered with respect to any date unless it shall have notified the applicable
Borrower that it will demand compensation for such costs or reductions under
paragraph (c) above not more than 90 days after the later of (i) such date and
(ii) the date on which it shall have become aware of such costs or reductions.
The protection of this Section shall be available to each Lender and each
Fronting Bank regardless of any possible contention of the invalidity or
inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.

         (e) Each Lender and each Fronting Bank agrees that it will designate a
different lending office if such designation will avoid the need for, or reduce
the amount of, such compensation

<PAGE>

                                                                              24

and will not, in the reasonable judgment of such Lender or such Fronting Bank
(as the case may be), be disadvantageous to such Lender or such Fronting Bank
(as the case may be).

         SECTION 2.12.     Change in Legality.

         (a) Notwithstanding any other provision herein, if any change in any
law or regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation 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 Borrowers and to the Agent, such Lender may:

                (i)     declare that Eurodollar Loans will not thereafter be
         made by such Lender hereunder, whereupon any request for a Eurodollar
         Borrowing shall, as to such Lender only, be deemed a request for an ABR
         Loan unless such declaration shall be subsequently withdrawn (any
         Lender delivering such a declaration hereby agreeing to withdraw such
         declaration promptly upon determining that such event of illegality no
         longer exists); and

                (ii)    require that all outstanding Eurodollar Loans made by it
         be converted to ABR Loans, in which event all such Eurodollar Loans
         shall be automatically converted to ABR Loans as of the effective date
         of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) 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
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b) For purposes of this Section 2.12, a notice by any Lender shall be
effective as to each Eurodollar Loan, if lawful, on the last day of the Interest
Period currently applicable to such Eurodollar Loan; in all other cases such
notice shall be effective on the date of receipt.

         SECTION 2.13.     Pro Rata Treatment.

         Except as required under Sections 2.12 and 2.17, each Extension of
Credit, each payment or prepayment of principal of any Borrowing, each payment
of interest on the Loans, each payment of a reimbursement obligation in respect
of a drawn Letter of Credit, each payment of the Facility Fees, each reduction
of the Commitments and each refinancing or conversion of any Borrowing with a
Borrowing of any Type, shall be allocated pro rata among the Lenders in
accordance with their respective Commitments (or, if such Commitments shall have
expired or been terminated, in accordance with the respective principal amounts
of their Outstanding Credits). For purposes of determining the available
Commitments of the Lenders at any time, the LC Outstandings shall be deemed to
have utilized the Commitments of the Lenders pro rata in accordance with their
respective Commitments. Each Lender agrees that in computing such Lender's
portion of any Extension of Credit to be made hereunder, the Agent may, in its
discretion, round each Lender's percentage of such Extension of Credit to the
next higher or lower whole dollar amount.

                                                                              25

         SECTION 2.14. Sharing of Setoffs.

         Each Lender agrees that if it shall, through the exercise of a right of
banker's lien, setoff or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Bankruptcy Code or other security
or interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, obtain payment (voluntary or involuntary) in
respect of any Loans or LC Outstandings as a result of which the unpaid
principal portion of its Loans and LC Outstandings shall be proportionately less
than the unpaid principal portion of the Loans and LC Outstandings of any other
Lender, it shall be deemed simultaneously to have purchased from such other
Lender at face value, and shall promptly pay to such other Lender the purchase
price for, a participation in the Loans or LC Outstandings of such other Lender,
so that the aggregate unpaid principal amount of the Loans and LC Outstandings
and participations in the Loans and LC Outstandings held by each Lender shall be
in the same proportion to the aggregate unpaid principal amount of all Loans and
LC Outstandings then outstanding as the principal amount of its Loans and LC
Outstandings prior to such exercise of banker's lien, setoff or counterclaim or
other event was to the principal amount of all Loans and LC Outstandings
outstanding prior to such exercise of banker's lien, setoff or counterclaim or
other event; provided, however, that, if any such purchase or purchases or
adjustments shall be made pursuant to this Section 2.14 and the payment giving
rise thereto shall thereafter be recovered, such purchase or purchases or
adjustments shall be rescinded to the extent of such recovery and the purchase
price or prices or adjustment restored without interest. Each Borrower expressly
consents to the foregoing arrangements and agrees that any Lender holding a
participation in a Loan or any LC Outstandings deemed to have been so purchased
may exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by such Borrower to such Lender by reason
thereof as fully as if such Lender had made an Extension of Credit in the amount
of such participation.

         Section 2.15. Payments.

         (a) Each Borrower shall make each payment (including principal of or
interest on any Outstanding Credit or any Fees or other amounts) hereunder from
an account in the United States not later than 12:00 noon, New York City time,
on the date when due in dollars to the Agent at its offices at One Chase
Manhattan Plaza, 8th Floor, New York, New York 10081, Attention of Lisa
Pucciarelli (Telecopy No. 212-552-5777), in immediately available funds. Each
such payment shall be made without off-set, deduction or counterclaim,
provided, that the foregoing shall not constitute a relinquishment or waiver of
such Borrower's rights to any independent claim that such Borrower may have
against the Agent, any Fronting Bank or any Lender.

         (b) Whenever any payment (including principal of or interest on any
Outstanding Credit or any Fees or other amounts) hereunder shall become due, or
otherwise would occur, on a day that is not a Business Day, such payment may be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of interest or Fees, if applicable.

<PAGE>

                                                                              26

         Section 2.16. Taxes.

         (a) Any and all payments of principal and interest on any of the
Outstanding Credits, or of any Fees or indemnity or expense reimbursements by a
Borrower hereunder ("Borrower Payments") shall be made, in accordance with
Section 2.15, free and clear of and without deduction for any and all current
or future United States Federal, state and local taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect to such
Borrower Payments, but only to the extent reasonably attributable to such
Borrower Payments, excluding (i) income taxes imposed on the net income of the
Agent, any Fronting Bank or any Lender (or any transferee or assignee thereof,
including a participation holder (any such entity a "Transferee")) and (ii)
franchise taxes imposed on the net income of the Agent, any Fronting Bank or
any Lender (or Transferee), in each case by the jurisdiction under the laws of
which the Agent, such Fronting Bank or such Lender (or Transferee) is organized
or doing business through offices or branches located therein, or any political
subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, "Taxes").
If any Borrower shall be required to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender (or any Transferee) or the Agent or any
Fronting Bank, (i) the sum payable shall be increased by the amount (an
"additional amount") necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.16) such Lender (or Transferee) or the Agent or such Fronting Bank (as the
case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (ii) such Borrower shall make such deductions
and (iii) such Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

         (b) In addition, each Borrower shall pay to the relevant United States
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or the
Letter Agreements ("Other Taxes").

         (c) Each Borrower shall indemnify each Lender (or Transferee thereof),
the Agent and each Fronting Bank for the full amount of Taxes and Other Taxes
with respect to Borrower Payments paid by such person, and any liability
(including penalties, interest and expenses (including reasonable attorney's
fees and expenses)) arising therefrom or with respect thereto, whether or not
such Taxes or Other Taxes were correctly or legally asserted by the relevant
United States Governmental Authority. A certificate setting forth and
containing an explanation in reasonable detail of the manner in which such
amount shall have been determined and the amount of such payment or liability
prepared by a Lender, a Fronting Bank or the Agent on their behalf, absent
manifest error, shall be final, conclusive and binding for all purposes. Such
indemnification shall be made within 30 days after the date the Lender (or
Transferee) or the Agent or the Fronting Bank, as the case may be, makes
written demand therefor.

         (d) If a Lender (or Transferee) or the Agent or a Fronting Bank shall
become aware that it is entitled to claim a refund from a United States
Governmental Authority in respect of Taxes or Other Taxes as to which it has
been indemnified by a Borrower, or with respect to which a Borrower has paid
additional amounts, pursuant to this Section 2.16, it shall promptly notify

<PAGE>

                                                                              27

such Borrower of the availability of such refund claim and shall, within 30
days after receipt of a request by such Borrower, make a claim to such United
States Governmental Authority for such refund at such Borrower's expense. If a
Lender (or Transferee) or the Agent or a Fronting Bank receives a refund
(including pursuant to a claim for refund made pursuant to the preceding
sentence) in respect of any Taxes or Other Taxes as to which it has been
indemnified by a Borrower or with respect to which a Borrower had paid
additional amounts pursuant to this Section 2.16, it shall within 30 days from
the date of such receipt pay over such refund to such Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by such Borrower
under this Section 2.16 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of such Lender (or Transferee)
or the Agent or such Fronting Bank and without interest (other than interest
paid by the relevant United States Governmental Authority with respect to such
refund); provided, however, that such Borrower, upon the request of such Lender
(or Transferee) or the Agent or such Fronting Bank, agrees to repay the amount
paid over to such Borrower (plus penalties, interest or other charges) to such
Lender (or Transferee) or the Agent or such Fronting Bank in the event such
Lender (or Transferee) or the Agent or such Fronting Bank is required to repay
such refund to such United States Governmental Authority.

         (e) As soon as practicable, but in any event within 30 days, after the
date of any payment of Taxes or Other Taxes by a Borrower to the relevant
United States Governmental Authority, such Borrower will deliver to the Agent,
at its address referred to in Section 8.01, the original or a certified copy of
a receipt issued by such United States Governmental Authority evidencing
payment thereof.

         (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.16 shall
survive the payment in full of the principal of and interest on all Outstanding
Credits hereunder.

         (g) Each of the Agent, each Fronting Bank and each Lender (or
Transferee) that is organized under the laws of a jurisdiction other than the
United States, any State thereof or the District of Columbia (a "Non-U.S.
Lender" or "Non U.S. Agent", as applicable) shall deliver to the Borrowers and
the Agent two copies of either United States Internal Revenue Service Form
W-8BEN or Form W-8ECI, properly completed and duly executed by such Non-U.S.
Lender claiming complete exemption from, or reduced rate of, United States
Federal withholding tax on payments by any Borrower under this Agreement. Such
forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of a Transferee that is a
participation holder, on or before the date such participation holder becomes a
Transferee hereunder) and on or before the date, if any, such Non-U.S. Lender
changes its applicable lending office by designating a different lending office
(a "New Lending Office"). In addition, each Non-U.S. Lender shall deliver such
forms promptly upon the obsolescence or invalidity of any form previously
delivered by such Non-U.S. Lender. Notwithstanding any other provision of this
Section 2.16(g), a Non-U.S. Lender shall not be required to deliver any form
pursuant to this Section 2.16(g) that such Non-U.S. Lender is not legally able
to deliver.

         (h) A Borrower shall not be required to indemnify any Non-U.S. Lender
or Non-U.S. Agent (including any Transferee), or to pay any additional amounts
to any Non-U.S. Lender or Non-U.S. Agent (including any Transferee), in respect
of United States Federal, state or local

<PAGE>

                                                                              28

withholding tax pursuant to paragraph (a) or (c) above to the extent that (i)
the obligation to withhold amounts with respect to United States Federal, state
or local withholding tax existed on the date such Non-U.S. Lender became a
party to this Agreement (or, in the case of a Transferee that is a
participation holder, on the date such participation holder became a Transferee
hereunder) or, with respect to payments to a New Lending Office, the date such
Non-U.S. Lender designated such New Lending Office with respect to an Extension
of Credit; provided, however, that this clause (i) shall not apply to any
Transferee or New Lending Office that becomes a Transferee or New Lending
Office as a result of an assignment, participation, transfer or designation
made at the request of such Borrower; and provided further, however, that this
clause (i) shall not apply to the extent the indemnity payment or additional
amounts any Transferee, or any Fronting Bank or any Lender (or Transferee)
through a New Lending Office, would be entitled to receive (without regard to
this clause (i)) do not exceed the indemnity payment or additional amounts that
the person making the assignment, participation or transfer to such Transferee,
or such Fronting Bank or Lender (or Transferee) making the designation of such
New Lending Office, would have been entitled to receive in the absence of such
assignment, participation, transfer or designation or (ii) the obligation to
pay such additional amounts or such indemnity payments would not have arisen
but for a failure by such Non-U.S. Lender (including any Transferee) to comply
with the provisions of paragraph (g) above and (i) below.

         (i) Any Fronting Bank or any Lender (or Transferee) claiming any
indemnity payment or additional amounts payable pursuant to this Section 2.16
shall use reasonable efforts (consistent with legal and regulatory
restrictions) to file any certificate or document reasonably requested in
writing by a Borrower or to change the jurisdiction of its applicable lending
office if the making of such a filing or change would avoid the need for or
reduce the amount of any such indemnity payment or additional amounts that may
thereafter accrue and would not, in the good faith determination of such
Fronting Bank or such Lender (or Transferee) (as the case may be), be otherwise
disadvantageous to such Fronting Bank or such Lender (or Transferee) (as the
case may be).

         (j) Nothing contained in this Section 2.16 shall require any Lender (or
Transferee) or the Agent or any Fronting Bank to make available to such Borrower
any of its tax returns (or any other information) that it deems to be
confidential or proprietary.

         (k) Notwithstanding anything herein to the contrary, the
indemnification obligations under this Section shall, to the extent
practicable, be allocated between the Borrowers based upon their relative
liability for the interest, fee or other payments in respect of which such
indemnification obligations arise.

         SECTION 2.17. Assignment of Commitments Under Certain Circumstances.

         In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.11 or 2.12, or any Borrower shall be required
to make additional payments to any Lender under Section 2.16, the Borrowers
shall have the right, at their own expense, upon notice to such Lender and the
Agent, to require such Lender to transfer and assign without recourse (in
accordance with and subject to the restrictions contained in Section 8.04) all
such Lender's interests, rights and obligations contained hereunder to another

the Agent and the Borrowers (which approval shall not be unreasonably withheld)
which shall assume such obligations; provided that (i) no such assignment shall
conflict with any law, rule or regulation or order of any Governmental
Authority and (ii) the assignee shall pay to the affected Lender in immediately

         SECTION 2.18. Term Loans.

         On the last day of the Revolving Period, if and only if on such date
(i) Loans are outstanding and (ii) no Default or Event of Default shall have
occurred and be continuing, the Maturity Date shall be extended for a period of
one year from the last day of the Revolving Period.

     1)  Letters of Credit

         (a) Subject to the terms and conditions hereof, each Letter of Credit
shall be issued (or the stated maturity thereof extended or terms thereof
modified or amended) on not less than three Business Days' prior notice thereof
by the delivery by a Borrower of a Request for Issuance to the Agent (which
shall promptly distribute copies thereof to the Lenders) and the Fronting Bank
designated by such Borrower. Each Request for Issuance shall identify the
Borrower for the account of which the Letter of Credit is proposed to be issued
and the relevant Fronting Bank and shall specify (i) the date (which shall be a
Business Day) of issuance of such Letter of Credit (or the date of
effectiveness of such extension, modification or amendment) and the stated
expiry date thereof (which shall be no later than the fifth Business Day
preceding the last day of the Revolving Period), (ii) the proposed stated
amount (denominated in dollars) of such Letter of Credit (which shall not be
less than $1,000,000, unless otherwise agreed to by the applicable Fronting
Bank), (iii) the name and address of the beneficiary of such Letter of Credit
and (iv) a statement of drawing conditions applicable to such Letter of Credit,
and if such Request for Issuance relates to an amendment or modification of a
Letter of Credit, it shall be accompanied by the consent of the beneficiary of
the Letter of Credit thereto. Each Request for Issuance shall be irrevocable
unless modified or rescinded by the Borrower that delivered such request not
less than two days prior to the proposed date of issuance (or effectiveness)
specified therein. Not later than 12:00 noon (New York City time) on the
proposed date of issuance (or effectiveness) specified in such Request for
Issuance, and upon fulfillment of the applicable conditions precedent and the
other requirements set forth herein, the applicable Fronting Bank shall issue
(or extend, amend or modify) such Letter of Credit and provide notice and a
copy thereof to the Agent, which shall promptly furnish copies thereof to the
Lenders. Each Lender shall, upon the issuance of any Letter of Credit, acquire
a participation interest in such Letter of Credit, automatically and without
any action on its part or the part of the applicable Fronting Bank, whereby
such Lender shall become obligated to perform such obligations in respect of
such Letter of Credit as are expressly set forth herein. No Fronting Bank shall
at any time be obligated to issue any Letter of Credit if such issuance would
conflict with any applicable requirement of law.

                                                                              30

         (b) No Letter of Credit shall be requested or issued hereunder if,
after the issuance thereof, the Outstanding Credits would exceed the Total
Commitment.

         (c) Each of the Borrowers hereby agrees to pay to the Agent for the
account of each Fronting Bank and, if they shall have funded participations in
the reimbursement obligations of such Borrower pursuant to subsection (d)
below, the Lenders, on demand made by such Fronting Bank to such Borrower, on
and after each date on which such Fronting Bank shall pay any amount under any
Letter of Credit issued by such Fronting Bank for the account of such Borrower,
a sum equal to the amount so paid plus interest on such amount from the date so
paid by such Fronting Bank until repayment to such Fronting Bank in full at a
fluctuating interest rate per annum equal to the Alternate Base Rate plus the
Applicable Margin for ABR Loans plus, if any amount paid by such Fronting Bank
under a Letter of Credit is not reimbursed by such Borrower within three
Business Days, 2%.

         (d) If any Fronting Bank shall not have been reimbursed in full by a
Borrower for any payment made by such Fronting Bank under a Letter of Credit
issued by such Fronting Bank for the account of such Borrower on the date of
such payment, such Fronting Bank shall give the Agent and each Lender prompt
notice thereof (an "LC Payment Notice") no later than 12:00 noon (New York City
time) on the Business Day immediately succeeding the date of such payment by
such Fronting Bank. Notwithstanding any provision of this Agreement to the
contrary, each Lender severally agrees to fund its participation in the
reimbursement obligation of the Borrower to each Fronting Bank by paying to the
Agent for the account of such Fronting Bank an amount equal to such Lender's
Percentage of such unreimbursed amount paid by such Fronting Bank, plus
interest on such amount at a rate per annum equal to the Federal Funds
Effective Rate from the date of the payment by such Fronting Bank to the date
of payment to such Fronting Bank by such Lender. Each such payment by a Lender
shall be made not later than 3:00 p.m. (New York City time) on the later to
occur of (i) the Business Day immediately following the date of such payment by
such Fronting Bank and (ii) the Business Day on which the Lender shall have
received an LC Payment Notice from such Fronting Bank. Each Lender's obligation
to make each such payment to the Agent for the account of each Fronting Bank
shall be several and shall not be affected by the occurrence or continuance of
a Default or Event of Default or the failure of any other Lender to make any
payment under this Section 2.19(d). Each Lender further agrees that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever.

         (e) The failure of any Lender to make any payment to the Agent for the
account of any Fronting Bank in accordance with subsection (d) above shall not
relieve any other Lender of its own obligation to make any similar payment to
the Agent, but no Lender shall be responsible for the failure of any other
Lender to make any such payment. If any Lender (a "non-performing Lender")
shall fail to make any payment to the Agent for the account of any Fronting
Bank in accordance with subsection (d) above within five Business Days after
the LC Payment Notice relating thereto, then, for so long as such failure shall
continue, (i) such Fronting Bank shall be deemed to be a Lender hereunder owed
a Loan, and for purposes of voting rights hereunder, having a Commitment, in an
amount equal to the outstanding principal

<PAGE>

                                                                              31

amount due and payable by such non-performing Lender to the Agent for the
account of such Fronting Bank pursuant to subsection (d) above and (ii) for
purposes of voting rights hereunder, the Commitment of such non-performing
Lender shall be reduced in an amount equal to such outstanding principal amount
due and payable by such non-performing Lender. Any non-performing Lender and
the Borrower for the account of which the relevant Letter of Credit was issued
(without waiving any claim against such Lender for such Lender's failure to
fund a participation in the reimbursement obligations of such Borrower under
subsection (d) above) severally agree to pay to the Agent for the account of
the applicable Fronting Bank forthwith on demand such amount, together with
interest thereon for each day from the date such Lender would have funded its
participation had it complied with the requirements of subsection (d) above
until the date such amount is paid to the Agent at (A) in the case of such
Borrower, the interest rate applicable at the time to ABR Loans (or the
interest rate that would be applicable if ABR Loans were outstanding) and (B)
in the case of such Lender, the Federal Funds Effective Rate.

         (f) The payment obligations of each Lender under Section 2.19(d) and of
each Borrower under this Agreement in respect of any payment under any Letter
of Credit shall be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances, including,
without limitation, the following circumstances:

               (i)      any lack of validity or enforceability of this
         Agreement or any other agreement or instrument relating
         hereto or to such Letter of Credit;

               (ii)     any amendment or waiver of, or any consent to departure
         from, the terms of this Agreement or such Letter
         of Credit;

               (iii)    the existence of any claim, set-off, defense or other
         right that the Borrower for the account of which such Letter of
         Credit was issued may have at any time against any beneficiary, or
         any transferee, of such Letter of Credit (or any persons for whom any
         such beneficiary or any such transferee may be acting), any Fronting
         Bank, or any other person, whether in connection with this Agreement,
         the transactions contemplated hereby or by such Letter of Credit, or
         any unrelated transaction;

               (iv)     any statement or any other document presented under such
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

               (v)      payment in good faith by any Fronting Bank under the
         Letter of Credit issued by such Fronting Bank against presentation of
         a draft or certificate which does not comply with the terms of such
         Letter of Credit; or

               (vi)     any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing.

         (g) Each Borrower assumes all risks of the acts and omissions of any
beneficiary or transferee of any Letter of Credit issued for the account of
such Borrower. Neither any Fronting Bank, any Lender nor any of their
respective officers, directors, employees, agents or Affiliates shall be liable
or responsible for (i) the use that may be made of such Letter of Credit or any
acts or omissions of any beneficiary or transferee thereof in connection
therewith; (ii) the validity, sufficiency or genuineness of documents, or of
any endorsement thereon, even if such documents should prove to be in any or
all respects invalid, insufficient, fraudulent or forged; (iii) payment by any
Fronting Bank against presentation of documents that do not comply with the
terms of

<PAGE>

                                                                              32

such Letter of Credit, including failure of any documents to bear any reference
or adequate reference to such Letter of Credit; or (iv) any other circumstances
whatsoever in making or failing to make payment under such Letter of Credit,
except that the Borrower for the account of which such Letter of Credit was
issued and each Lender shall have the right to bring suit against the
applicable Fronting Bank, and such Fronting Bank shall be liable to such
Borrower and any Lender, to the extent of any direct, as opposed to
consequential, damages suffered by such Borrower or such Lender which such
Borrower or such Lender proves were caused by such Fronting Bank's willful
misconduct or gross negligence, including, in the case of such Borrower, such
Fronting Bank's willful failure to make timely payment under such Letter of
Credit following the presentation to it by the beneficiary thereof of a draft
and accompanying certificate(s) which strictly comply with the terms and
conditions of such Letter of Credit. In furtherance and not in limitation of
the foregoing, each Fronting Bank may accept sight drafts and accompanying
certificates presented under any Letter of Credit issued by such Fronting Bank
that appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary, and
payment against such documents shall not constitute willful misconduct or gross
negligence by such Fronting Bank. Without limiting the foregoing, no Lender
shall be obligated to indemnify any Borrower for damages caused by any Fronting
Bank's willful misconduct or gross negligence.

         (h) If there shall be more than one Fronting Bank that has issued a
Letter of Credit at any time hereunder, each such Fronting Bank shall, with
respect to the Letters of Credit issued by it and the reimbursement obligations
owing to it, be regarded hereunder as the "Fronting Bank" and shall have all of
the rights, interests, protections and obligations of the "Fronting Bank"
hereunder with respect to such Letters of Credit and reimbursement obligations
and all matters relating thereto. Whenever any action may be, or is required to
be, taken by the Fronting Bank hereunder, each Fronting Bank may, or shall,
take such action only in respect of the Letters of Credit issued by it and the
reimbursement obligations owing to it. Whenever the consent of the Fronting
Bank is required hereunder with respect to any proposed action, the consent of
each Fronting Bank of a Letter of Credit that is then outstanding, or in
respect of which reimbursement obligations remain outstanding, shall be
required for such proposed action to be taken. Any notice to be provided to the
Fronting Bank shall be provided to each Fronting Bank of a Letter of Credit
that is then outstanding, or in respect of which reimbursement obligations
remain outstanding, and each such Fronting Bank shall have the right to request
any information, and take any other action, as the Fronting Bank is permitted
to do hereunder. The protections accorded the Fronting Bank hereunder shall
inure to the benefit of each Fronting Bank, regardless of whether any Letter of
Credit issued by any such Fronting Bank or any reimbursement obligations in
respect thereof are outstanding at the time the benefits of such protections
are asserted.

         The Commitment of each Lender to make its initial Loan and of each

is subject to the conditions that on or prior to the date of such Extension of
Credit:

         (a) The Agent shall have received favorable written legal opinions of

         (k) one or more judgments or orders for the payment of money in an

shall, by notice to the affected Borrower(s), take one or all of the following
actions, at the same or different times: (i) terminate forthwith the right of
such affected Borrower(s) to request and receive Extensions of Credit; (ii) to
the extent such event would permit the Lenders and the Fronting Banks to
withhold Extensions of Credit to any other Borrower pursuant to Section 4.02(c)
or (d), terminate forthwith the right of such other Borrower to request and
receive Extensions of Credit; and (iii) declare the Loans of the affected
Borrower(s) then outstanding to be forthwith due and payable in whole or in
part, whereupon the principal of the Loans so declared to be due and payable,

other liabilities of such Borrower(s) accrued hereunder, shall become forthwith
due and payable, without presentment, demand, protest or any other notice of
any kind, all of which are hereby expressly waived, anything contained herein
to the contrary notwithstanding; provided that in the case of any event
described in paragraph (h) or (i) above affecting any Borrower, the right of
such Borrower to request and receive Extensions of Credit shall automatically
terminate and the principal of the Loans then outstanding of such Borrower,
together with accrued interest thereon and any unpaid accrued Fees and all
other liabilities of such Borrower accrued hereunder shall automatically become
due and payable, without presentment, demand, protest or any other notice of

contained herein to the contrary notwithstanding.

         Notwithstanding anything to the contrary contained herein, no notice
given or declaration made by the Agent pursuant to this Article VI shall affect
(i) the obligation of any Fronting Bank to make any payment under any Letter of
Credit issued by such Fronting Bank in accordance with the terms of such Letter
of Credit or (ii) the obligations of each Lender in respect of each such Letter
of Credit; provided, however, that upon the occurrence and during the
continuance of any Event of Default affecting any Borrower, the Agent shall at
the request, or may with the consent, of the Required Lenders, upon notice to
such Borrower, require such Borrower to deposit with the Agent an amount in the
cash collateral account (the "Cash Collateral Account") described below equal to
the aggregate maximum amount available to be drawn under all Letters of Credit
issued for the account of such Borrower and outstanding at such time. Such Cash
Collateral Account shall at all times be free and clear of all rights or claims
of third parties. The Cash Collateral Account shall be maintained with the Agent
in the name of, and under the sole dominion and control of, the Agent, and
amounts deposited in the Cash Collateral Account shall bear interest at a rate
equal to the rate generally offered by JPMorgan Chase for deposits equal to the
amount deposited by such Borrower in the Cash Collateral Account, for a term to
be determined by the Agent in its sole discretion. Each Borrower hereby grants
to the Agent for the benefit of the Fronting Banks and the Lenders a Lien on,
and hereby assigns to the Agent for the benefit of the Fronting Banks and the
Lenders all of its right, title and interest in, the Cash

Collateral Account and all funds from time to time on deposit therein to secure
its reimbursement obligations in respect of Letters of Credit issued for its
account. If any drawings then outstanding or thereafter made are not reimbursed
in full immediately upon demand or, in the case of subsequent drawings, upon
being made, then, in any such event, the Agent may apply the amounts then on
deposit in the Cash Collateral Account, in such priority as the Administrative
Agent shall elect, toward the payment in full of any or all of any Borrower's
obligations hereunder as and when such obligations shall become due and
payable, regardless of whether the amounts to be so applied were deposited by
the Borrower for the account of which the Letter(s) of Credit then being drawn
were issued. Upon payment in full, after the termination of the Letters of
Credit, of all such obligations, the Agent will repay and reassign to the
relevant Borrowers any cash then on deposit in the Cash Collateral Account and
the Lien of the Agent on the Cash Collateral Account and the funds therein
shall automatically terminate.

                                   ARTICLE VII
                                    THE AGENT

         In order to expedite the transactions contemplated by this Agreement,
JPMorgan Chase is hereby appointed to act as Agent on behalf of the Lenders and
the Fronting Banks. Each Lender and each Fronting Bank hereby irrevocably
authorizes the Agent to take such actions on behalf of such Lender and such
Fronting Bank and to exercise such powers as are specifically delegated to the
Agent by the terms and provisions hereof, together with such actions and powers
as are reasonably incidental thereto. The Agent is hereby expressly authorized
by the Lenders and the Fronting Banks, without hereby limiting any implied
authority, (a) to receive on behalf of the Lenders and the Fronting Banks all
payments of principal of and interest on the Outstanding Credits and all other
amounts due to the Lenders and the Fronting Banks hereunder, and promptly to
distribute to each Lender and each Fronting Bank, its proper share of each
payment so received; (b) to give notice on behalf of each Lender and each
Fronting Bank to the Borrowers of any Event of Default of which the Agent has
actual knowledge acquired in connection with its agency hereunder; and (c) to
distribute to each Lender and each Fronting Bank copies of all notices,
financial statements and other materials delivered by the Borrowers pursuant to
this Agreement as received by the Agent.

         Neither the Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its or his or her own gross negligence or willful misconduct, or be
responsible for any statement, warranty or representation herein or the contents
of any document delivered in connection herewith, or be required to ascertain or
to make any inquiry concerning the performance or observance by the Borrowers of
any of the terms, conditions, covenants or agreements contained in this
Agreement. The Agent shall not be responsible to the Lenders or the Fronting
Banks for the due execution, genuineness, validity, enforceability or
effectiveness of this Agreement or other instruments or agreements. The Agent
may deem and treat the Lender or the Fronting Bank that makes any Extension of
Credit as the holder of the indebtedness resulting therefrom for all purposes
hereof until it shall have received notice from such Lender or such Fronting
Bank, given as provided herein, of the transfer thereof. The Agent shall in all
cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders and, except as
otherwise specifically provided herein, such instructions and any action or
inaction pursuant

<PAGE>

                                                                              49

thereto shall be binding on all the Lenders and the Fronting Banks. The Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Agent nor any of its directors, officers, employees or agents shall have any
responsibility to the Borrowers on account of the failure of or delay in
performance or breach by any Lender or any Fronting Bank of any of its
obligations hereunder or to any Lender or any Fronting Bank on account of the
failure of or delay in performance or breach by any other Lender, any Fronting
Bank or any Borrower of any of their respective obligations hereunder or in
connection herewith. The Agent may execute any and all duties hereunder by or
through agents or employees and shall be entitled to rely upon the advice of
legal counsel selected by it with respect to all matters arising hereunder and
shall not be liable for any action taken or suffered in good faith by it in
accordance with the advice of such counsel.

         The Lenders and the Fronting Banks hereby acknowledge that the Agent
shall not be under any duty to take any discretionary action permitted to be
taken by it pursuant to the provisions of this Agreement unless it shall be
requested in writing to do so by the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, the Agent may resign at any time by notifying the Lenders, the
Fronting Banks and the Borrowers. Upon any such resignation, the Required
Lenders shall have the right to appoint a successor Agent acceptable to the
Borrowers. If no successor shall have been so appointed by the Required Lenders
and shall have accepted such appointment within 30 days after the Agent gives
notice of its resignation, then the Agent may, on behalf of the Lenders and the
Fronting Banks, appoint a successor Agent, having a combined capital and surplus
of at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance
of any appointment as Agent hereunder by a successor bank, such successor shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent and the Agent shall be discharged from its duties and
obligations hereunder. After the Agent's resignation hereunder, the provisions
of this Article and Section 8.05 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Agent.

         With respect to the Extensions of Credit made by it hereunder, the
Agent, in its individual capacity and not as Agent, shall have the same rights
and powers as any other Lender and may exercise the same as though it were not
the Agent, and the Agent and its Affiliates may accept deposits from, lend money
to and generally engage in any kind of business with the Borrowers or any
Subsidiary or other Affiliate thereof as if it were not Agent.

         Each Lender agrees (i) to reimburse the Agent, on demand, in the amount
of its pro rata share (based on its Commitment hereunder or, if the Commitments
shall have been terminated, the amount of its percentage of Outstanding Credits)
of any expenses incurred for the benefit of the Lenders or the Fronting Banks,
in its role as Agent, including counsel fees and compensation of agents and
employees paid for services rendered on behalf of the Lenders or the Fronting
Banks, which shall not have been reimbursed by the Borrowers and (ii) to
indemnify and hold harmless the Agent and any of its directors, officers,
employees or agents, on demand, in the amount of such pro rata share, from and
against any and all liabilities, taxes, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or

<PAGE>

                                                                              50

nature whatsoever which may be imposed on, incurred by or asserted against it
in any way relating to or arising out of this Agreement or any action taken or
omitted by it under this Agreement to the extent the same shall not have been
reimbursed by the Borrowers; provided that neither any Lender nor any Fronting
Bank shall be liable to the Agent for 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 Agent or any of its directors, officers, employees or agents.
Each Lender and each Fronting Bank agrees that any allocation made in good
faith by the Agent of expenses or other amounts referred to in this paragraph
shall be conclusive and binding for all purposes.

         Each Lender and each Fronting Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Lender or
Fronting Bank, and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender and each Fronting Bank also acknowledges that it will,
independently and without reliance upon the Agent or any other Lender or
Fronting Bank, and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement or any related agreement or any
document furnished hereunder or thereunder.

         Bank of America, N.A. shall not, by virtue of its designation as
"Syndication Agent" and neither J.P. Morgan Securities, Inc. nor Banc of America
Securities LLC shall, by virtue of their designation as "Joint Lead Arrangers"
and "Co-Book Managers", have any duties, liabilities, obligations or
responsibilities under this Agreement other than, if applicable, as a Lender or
as a Fronting Bank hereunder.

or any Letter of Credit is available to be drawn.

         SECTION 8.03. Binding Effect.

financial statements delivered pursuant to Section 5.03 and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (v) such
assignee will independently and without reliance upon the Agent, such assigning
Lender or any other Lender or Fronting Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make its own

Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement. The Register shall be available for inspection by each party
hereto, at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance

however, that (i) such Lender's obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) each
participating bank or other entity shall be entitled to the benefit of the cost
protection provisions contained in Sections 2.11, 2.16 and 8.05 to the same
extent as if it were the selling Lender (and limited to the amount that could
have been claimed by the selling Lender had it continued to hold the interest
of such participating bank or other entity), except that all claims made
pursuant to such Sections shall be made through such selling Lender, and (iv)
the Borrowers, the Agent, the Fronting Banks and the other Lenders shall
continue to deal solely and directly with such selling Lender in connection
with such Lender's rights and obligations under this Agreement, and such Lender

provision of this Agreement (other than amendments, modifications or waivers

any scheduled principal payment date or date fixed for the payment of interest
on the Outstanding Credits or (z) extending the Commitments).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section,
disclose to the assignee or participant or proposed assignee or participant any
information relating to the Borrowers furnished to such Lender by or on behalf
of the Borrowers; provided that, prior to any such disclosure, each such
assignee or participant or proposed assignee or participant shall execute an
agreement whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of any such information.

         (h) The Borrowers shall not assign or delegate any rights and duties
hereunder without the prior written consent of all Lenders, and any attempted
assignment or delegation (except as a consequence of a transaction expressly
permitted under Section 5.09) by a Borrower without such consent shall be void.

         (i) Any Lender may at any time pledge all or any portion of its rights
under this Agreement to a Federal Reserve Bank; provided that no such pledge
shall release any Lender from its obligations hereunder or substitute any such
Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, each Borrower shall, at the

<PAGE>

                                                                              54

request of the assigning Lender, duly execute and deliver to the assigning
Lender a promissory note or notes evidencing the Loans made to such Borrower by
the assigning Lender hereunder.

         (j) Subject to the appointment and acceptance of a successor Fronting
Bank as provided below, any Fronting Bank may resign at any time by notifying
the Lenders and the Borrowers. Upon any such resignation, the Required Lenders
shall have the right to appoint a successor Fronting Bank acceptable to the
Borrowers. If no successor shall have been so appointed by the Required Lenders
and shall have accepted such appointment within 30 days after the retiring
Fronting Bank gives notice of its resignation, then the retiring Fronting Bank
may appoint a successor Fronting Bank, having a combined capital and surplus of
at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance of
any appointment as Fronting Bank hereunder by a successor bank, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Fronting Bank and the retiring Fronting Bank shall be
discharged from its duties and obligations hereunder. After a Fronting Bank's
resignation hereunder, the provisions of Sections 2.11, 2.16 and 8.05 shall
continue in effect for its benefit in respect of any actions taken or omitted
to be taken by it while it was acting as Fronting Bank.

         SECTION 8.05. Expenses; Indemnity.

         (a) Holdings agrees to pay all reasonable out-of-pocket expenses
(including reasonable fees, charges and disbursements of counsel) incurred by
the Agent in connection with the preparation, execution and delivery of this
Agreement or in connection with any amendments, modifications or waivers of the
provisions hereof (but only if such amendments, modifications or waivers are
requested by a Borrower) (whether or not the transactions hereby contemplated
are consummated), or incurred by the Agent, any Fronting Bank or any Lender in
connection with the enforcement of their rights in connection with this
Agreement (including in respect of workouts and restructurings) or in
connection with the Extensions of Credit made hereunder, including the
reasonable fees and disbursements of counsel for the Agent or, in the case of
enforcement following an Event of Default, the Lenders and the Fronting Banks.
In addition to the foregoing, each Borrower for the account of which a Letter
of Credit is issued shall pay or reimburse the Fronting Bank that issued such
Letter of Credit for such reasonable, normal and customary costs and expenses
as are incurred or charged by such Fronting Bank in issuing, negotiating,
effecting payment under, amending or otherwise administering such Letter of
Credit.

         (b) Each Borrower agrees to indemnify each Lender and each Fronting
Bank against any loss, calculated in accordance with the next sentence, or
reasonable expense that such Lender or such Fronting Bank may sustain or incur
as a consequence of (i) any failure by such Borrower to borrow or to refinance,
convert or continue any Loan hereunder (including as a result of such
Borrower's failure to fulfill any of the applicable conditions set forth in
Article IV) after irrevocable notice of such borrowing, refinancing, conversion
or continuation has been given pursuant to Section 2.03, (ii) any payment,
prepayment or conversion of a Eurodollar Loan of such Borrower, or assignment
of a Eurodollar Loan of such Borrower required by any other provision of this
Agreement or otherwise made or deemed made, on a date other than the last day
of the Interest Period, if any, applicable thereto, (iii) any default in
payment or prepayment of the principal amount of any Outstanding Credit or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, whether by scheduled maturity, acceleration, irrevocable
notice of prepayment or otherwise) or (iv) the occurrence of any Event of
Default

<PAGE>

                                                                              55

relating to such Borrower, including, in each such case, any loss or reasonable
expense sustained or incurred or to be sustained or incurred by such Lender in
liquidating or employing deposits from third parties, or with respect to
commitments made or obligations undertaken with third parties, to effect or
maintain any Loan hereunder or any part thereof as a Eurodollar Loan. Such loss
shall include an amount equal to the excess, if any, as reasonably determined
by such Lender, of (x) its cost of obtaining the funds for the Loan being paid,
prepaid, refinanced, converted or not borrowed (assumed to be the LIBO Rate for
the period from the date of such payment, prepayment, refinancing or failure to
borrow or refinance to the last day of the Interest Period for such Loan (or,
in the case of a failure to borrow or refinance, the Interest Period for such
Loan that would have commenced on the date of such failure) over (y) the amount
of interest (as reasonably determined by such Lender) that would be realized by
such Lender in reemploying the funds so paid, prepaid or not borrowed or
refinanced for such period or Interest Period, as the case may be.

         (c) Holdings agrees to indemnify the Agent, the Fronting Banks, each
Lender, each of their Affiliates and the directors, officers, employees and
agents of the foregoing (each such person being called an "Indemnitee")
against, and to hold each Indemnitee harmless from, any and all costs, losses,
claims, damages, liabilities and related expenses, including reasonable counsel
fees and expenses, incurred by or asserted against any Indemnitee arising out
of (i) the preparation, execution, delivery, enforcement, performance and
administration of this Agreement, (ii) the use of the proceeds of the
Extensions of Credit or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto, including any of the foregoing arising from the negligence,
whether sole or concurrent, on the part of any Indemnitee; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (i) are determined by
a final judgment of a court of competent jurisdiction to have resulted from the
gross negligence or willful misconduct of such Indemnitee or (ii) result from
any litigation brought by such Indemnitee against the Borrowers or by any
Borrower against such Indemnitee, in which a final, nonappealable judgment has
been rendered against such Indemnitee; provided, further, that each Borrower
agrees that it will not, nor will it permit any Subsidiary to, without the
prior written consent of each Indemnitee, settle, compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification could be sought under the
indemnification provisions of this Section 8.05(c) (whether or not any
Indemnitee is an actual or potential party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent does not include any
statement as to an admission of fault, culpability or failure to act by or on
behalf of any Indemnitee and does not involve any payment of money or other
value by any Indemnitee or any injunctive relief or factual findings or
stipulations binding on any Indemnitee.

         (d) The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement,
the consummation of the transactions contemplated hereby, the repayment of any
of the Outstanding Credits, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on behalf of the
Agent, any Lender or any Fronting Bank. All amounts due under this Section
shall be payable on written demand therefor.

         (e) A certificate of any Lender, any Fronting Bank or the Agent setting
forth any amount or amounts that such Lender, such Fronting Bank or such Agent
is entitled to receive pursuant to paragraph (b) of this Section and containing
an explanation in reasonable detail of the manner in which such amount or
amounts shall have been determined shall be delivered to the appropriate
Borrower and shall be conclusive absent manifest error.

         SECTION 8.06. Right of Setoff.

         If an Event of Default shall have occurred and be continuing, each
Lender and each Fronting Bank is hereby authorized at any time and from time to
time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender or such Fronting
Bank to or for the credit or the account of the applicable Borrower against any
of and all the obligations of such Borrower now or hereafter existing under this
Agreement held by such Lender or such Fronting Bank (as the case may be),
irrespective of whether or not such Lender or such Fronting Bank (as the case
may be), shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender and each Fronting Bank
under this Section are in addition to other rights and remedies (including other
rights of setoff) which such Lender or such Fronting Bank may have.

         SECTION 8.07. Applicable Law.

         THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK.

         SECTION 8.08. Waivers; Amendment.

         (a) No failure or delay of the Agent, any Fronting Bank or any Lender
in exercising any power or right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Agent, the Fronting Banks and
the Lenders hereunder are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Agreement or consent to any departure therefrom shall in any event be effective
unless the same shall be permitted by paragraph (b) below, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given. No notice or demand on any Borrower or any Subsidiary in any
case shall entitle such party to any other or further notice or demand in
similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrowers and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on, any Loan or reimbursement obligation in respect of a Letter of
Credit or date for the payment of any Facility Fee or LC Fee, or waive or
excuse any such payment or any part thereof, or decrease the rate of interest
on any Loan or any reimbursement obligation in respect of a Letter of Credit,
without the prior written consent of

<PAGE>

                                                                              57

each Lender affected thereby, (ii) increase the Commitment of any Lender,
decrease the Facility Fee or decrease the LC Fee payable to any Lender without
the prior written consent of such Lender, or (iii) amend or modify the
provisions of Section 2.13, 2.14 or Section 8.04(h), the provisions of this
Section or the definition of the "Required Lenders", without the prior written
consent of each Lender; provided further, however, that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Agent or any
Fronting Bank hereunder without the prior written consent of the Agent or the
applicable Fronting Bank, as the case may be. Each Lender and each Fronting
Bank shall be bound by any waiver, amendment or modification authorized by this
Section and any consent by any Lender, the Agent or any Fronting Bank pursuant
to this Section shall bind any assignee of its rights and interests hereunder.

         SECTION 8.09. Entire Agreement.

         This Agreement (including the schedules and exhibits hereto) and the
Letter Agreements represent the entire contract among the parties relative to
the subject matter hereof and thereof. Any previous agreement, whether written
or oral, among the parties with respect to the subject matter hereof, is
superseded by this Agreement and the Letter Agreements. There are no unwritten
oral agreements between the parties. Nothing in this Agreement, expressed or
implied, is intended to confer upon any party other than the parties hereto any
rights, remedies, obligations or liabilities under or by reason of this
Agreement.

         SECTION 8.10. Severability.

         In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby. The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 8.11. Counterparts.

         This Agreement may be executed in two or more counterparts, each of
which shall constitute an original but all of which when taken together shall
constitute but one contract, and shall become effective as provided in Section
8.03.

         SECTION 8.12. Headings.

         Article and Section headings and the Table of Contents used herein are
for convenience of reference only, are not part of this Agreement and are not to
affect the construction of, or to be taken into consideration in interpreting,
this Agreement.

         SECTION 8.13. Interest Rate Limitation.

         (a) Notwithstanding anything herein to the contrary, if at any time the
applicable interest rate, together with all fees and charges which are treated
as interest under applicable law (collectively the "Charges"), as provided for
herein or in any other document executed in connection herewith, or otherwise
contracted for, charged, received, taken or reserved by any

<PAGE>

                                                                              58

Lender or any Fronting Bank, shall exceed the maximum lawful rate (the "Maximum
Rate") which may be contracted for, charged, taken, received or reserved by
such Lender or such Fronting Bank (as the case may be) in accordance with
applicable law, the rate of interest payable on the Outstanding Credits of such
Lender or such Fronting Bank (as the case may be), together with all Charges
payable to such Lender or such Fronting Bank (as the case may be), shall be
limited to the Maximum Rate.

         (b) If the amount of interest, together with all Charges, payable for
the account of any Lender or any Fronting Bank in respect of any interest
computation period is reduced pursuant to paragraph (a) of this Section and the
amount of interest, together with all Charges, payable for such Lender's or
such Fronting Bank's (as the case may be) account in respect of any subsequent
interest computation period, computed pursuant to Section 2.07, would be less
than the Maximum Rate, then the amount of interest, together with all Charges,
payable for such Lender's or such Fronting Bank's (as the case may be) account
in respect of such subsequent interest computation period shall, to the extent
permitted by applicable law, be automatically increased to such Maximum Rate;
provided that at no time shall the aggregate amount by which interest paid for
the account of any Lender or any Fronting Bank has been increased pursuant to
this paragraph (b) exceed the aggregate amount by which interest, together with
all Charges, paid for its account has theretofore been reduced pursuant to
paragraph (a) of this Section.

         SECTION 8.14. Jurisdiction; Venue.

         (a) Each Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any New York State
court or Federal court of the United States of America sitting in New York
City, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may
be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Subject to the foregoing and to paragraph (b) below,
nothing in this Agreement shall affect any right that any party hereto may
otherwise have to bring any action or proceeding relating to this Agreement
against any other party hereto in the courts of any jurisdiction.

         (b) Each Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or thereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any New York State court or
Federal court of the United States of America sitting in New York City. Each of
the parties hereto hereby irrevocably waives, to the fullest extent permitted
by law, the defense of an inconvenient forum to the maintenance of such action
or proceeding in any such court.

         SECTION 8.15. Confidentiality.

         Each Lender and each Fronting Bank shall use its best efforts to hold
in confidence all information, memoranda, or extracts furnished to such Lender
or such Fronting Bank (as the case may be) (directly or through the Agent) by
the Borrowers hereunder or in connection with the negotiation hereof; provided
that such Lender and such Fronting Bank may disclose any such information,
memoranda or extracts (i) to its Affiliates, accountants or counsel, (ii) to any
regulatory agency having authority to examine such Lender or such Fronting Bank
(as the case may be), (iii) as required by any legal or governmental process or
otherwise by law, (iv) except as provided in the last sentence of Section 5.03,
to any person to which such Lender or such Fronting Bank (as the case may be)
sells or proposes to sell an assignment or a participation in its Outstanding
Credits hereunder, if such other person agrees for the benefit of the Borrowers
to comply with the provisions of this Section and (v) to the extent that such
information, memoranda or extracts shall be publicly available or shall have
become known to such Lender or such Fronting Bank (as the case may be)
independently of any disclosure by any Borrower hereunder or in connection with
the negotiation hereof. Notwithstanding the foregoing, any Lender and any
Fronting Bank may disclose the provisions of this Agreement, the amounts,
maturities and interest rates of its Outstanding Credits, and any Fees to which
it is entitled, to any purchaser or potential purchaser of such Lender's
interest in any Outstanding Credits.
