                                      LOANS

      2.1 AGGREGATE COMMITMENT.

      Subject to the terms and conditions set forth herein, each Lender
severally agrees to make Loans to the Borrower in Dollars, at any time and from
time to time, during the period from the Effective Date to the Maturity Date
(each a "Loan" and collectively the "Loans"); provided, however, that (i) the
aggregate amount of Loans outstanding shall not exceed the Aggregate Commitment
and (ii) with respect to each individual Lender, the Lender's Commitment
Percentage multiplied by the outstanding Loans shall not exceed such Lender's
Commitment. Subject to the terms of this Credit Agreement, the Borrower may
borrow, repay and reborrow Loans.

                                       12


      2.2 METHOD OF BORROWING FOR LOANS.

      By no later than 11:00 a.m. (a) on the date of the requested borrowing of
Loans that will be Base Rate Loans or (b) three Business Days prior to the date
of the requested borrowing of Loans that will be Eurodollar Loans, the Borrower
shall telephone the Administrative Agent as well as submit a written Notice of
Borrowing in the form of Exhibit 2.2 to the Administrative Agent setting forth
(i) the amount requested, (ii) whether such Loans shall accrue interest at the
Base Rate or the Adjusted Eurodollar Rate, (iii) with respect to Loans that will
be Eurodollar Loans, the Interest Period applicable thereto and (iv)
certification that the Borrower has complied in all respects with Section 5.2.

      2.3 FUNDING OF LOANS.

      Upon receipt of a Notice of Borrowing, the Administrative Agent shall
promptly inform the Lenders as to the terms thereof. Each such Lender shall make
its Commitment Percentage of the requested Loans available to the Administrative
Agent by 1:00 p.m. on the date specified in the Notice of Borrowing by deposit,
in Dollars, of immediately available funds at the Agency Services Address. The
amount of the requested Loans will then be made available to the Borrower by the
Administrative Agent by crediting the account of the Borrower on the books of
such office of the Administrative Agent, to the extent the amount of such Loans
are made available to the Administrative Agent.

      No Lender shall be responsible for the failure or delay by any other
Lender in its obligation to make Loans hereunder; provided, however, that the
failure of any Lender to fulfill its obligations hereunder shall not relieve any
other Lender of its obligations hereunder. Unless the Administrative Agent shall
have been notified by any Lender prior to 1:00 p.m. on the date specified in the
Notice of Borrowing that such Lender does not intend to make available to the
Administrative Agent its portion of the Loans to be made on such date, the
Administrative Agent may assume that such Lender has made such amount available
to the Administrative Agent on the date of such Loans, and the Administrative
Agent in reliance upon such assumption, may (in its sole discretion but without
any obligation to do so) make available to the Borrower a corresponding amount.
If such corresponding amount is not in fact made available to the Administrative
Agent, the Administrative Agent shall be able to recover such corresponding
amount from such Lender. If such Lender does not pay such corresponding amount
forthwith upon the Administrative Agent's demand therefor, the Administrative
Agent will promptly notify the Borrower, and the Borrower shall immediately pay
such corresponding amount to the Administrative Agent. The Administrative Agent
shall also be entitled to recover from the Lender or the Borrower, as the case
may be, interest on such corresponding amount in respect of each day from the
date such corresponding amount was made available by the Administrative Agent to
the Borrower to the date such corresponding amount is recovered by the
Administrative Agent at a per annum rate equal to (a) from the Borrower at the
applicable rate for such Loan pursuant to the Notice of Borrowing and (b) from a
Lender at the Federal Funds Rate.

      2.4 CONTINUATIONS AND CONVERSIONS.

      The Borrower shall have the option, on any Business Day, to continue
existing Eurodollar Loans for a subsequent Interest Period, to convert Base Rate
Loans into Eurodollar

                                       13


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

      2.5 MINIMUM AMOUNTS.

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

      2.6 REDUCTIONS OF AGGREGATE COMMITMENT.

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

      2.7 NOTES.

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

                                       14


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

                                   SECTION 3.

                                    PAYMENTS

      3.1 INTEREST.

            (a) Interest Rate.

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

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

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

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

      3.2 PREPAYMENTS.

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

                                       15


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

      3.3 PAYMENT IN FULL AT MATURITY.

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

      3.4 FEES.

            (a) Unused Fees.

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

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

            (b) Utilization Fees. For each day that the principal amount of
      outstanding Loans hereunder shall exceed an amount equal to thirty three
      and one third percent (33 1/3%) of the Aggregate Commitment, the Borrower
      shall pay to the Administrative Agent, for the pro rata benefit of the
      Lenders, a per annum fee equal to the Applicable Percentage for
      Utilization Fees (as set forth on the Pricing Schedule) on the outstanding
      principal balance of the Loans (the "Utilization Fees"). The Utilization
      Fees, if any, shall be due and payable in arrears five Business Days after
      the end of each fiscal quarter of the Borrower (as well as on the Maturity
      Date) for the immediately preceding fiscal quarter (or portion thereof),
      beginning with the first of such dates to occur after the Effective Date.

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

                                       16


      3.5 PLACE AND MANNER OF PAYMENTS.

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

      3.6 PRO RATA TREATMENT.

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

      3.7 COMPUTATIONS OF INTEREST AND FEES.

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

            (b) It is the intent of the Lenders and the Borrower to conform to
      and contract in strict compliance with applicable usury law from time to
      time in effect. All

                                       17


      agreements between the Lenders and the Borrower are hereby limited by the
      provisions of this paragraph which shall override and control all such
      agreements, whether now existing or hereafter arising and whether written
      or oral. In no way, nor in any event or contingency (including but not
      limited to prepayment or acceleration of the maturity of any obligation),
      shall the interest taken, reserved, contracted for, charged, or received
      under this Credit Agreement, under the Notes or otherwise, exceed the
      maximum nonusurious amount permissible under applicable law. If, from any
      possible construction of any of the Credit Documents or any other
      document, interest would otherwise be payable in excess of the maximum
      nonusurious amount, any such construction shall be subject to the
      provisions of this paragraph and interest owing pursuant to such documents
      shall be automatically reduced to the maximum nonusurious amount permitted
      under applicable law, without the necessity of execution of any amendment
      or new document. If any Lender shall ever receive anything of value which
      is characterized as interest on the Loans under applicable law and which
      would, apart from this provision, be in excess of the maximum lawful
      amount, an amount equal to the amount which would have been excessive
      interest shall, without penalty, be applied to the reduction of the
      principal amount owing on the Loans and not to the payment of interest, or
      refunded to the Borrower or the other payor thereof if and to the extent
      such amount which would have been excessive exceeds such unpaid principal
      amount of the Loans. The right to demand payment of the Loans or any other
      indebtedness evidenced by any of the Credit Documents does not include the
      right to receive any interest which has not otherwise accrued on the date
      of such demand, and the Lenders do not intend to charge or receive any
      unearned interest in the event of such demand. All interest paid or agreed
      to be paid to the Lenders with respect to the Loans shall, to the extent
      permitted by applicable law, be amortized, prorated, allocated, and spread
      throughout the full stated term (including any renewal or extension) of
      the Loans so that the amount of interest on account of such indebtedness
      does not exceed the maximum nonusurious amount permitted by applicable
      law.

      3.8 SHARING OF PAYMENTS.

      Each Lender agrees that, in the event that any Lender shall obtain payment
in respect of any Loan or any other obligation owing to such Lender under this
Credit Agreement through the exercise of a right of set-off, banker's lien,
counterclaim or otherwise (including, but not limited to, pursuant to the
Bankruptcy Code) in excess of its pro rata share as provided for in this Credit
Agreement, such Lender shall promptly purchase from the other Lenders a
participation in such Loans and other obligations, in such amounts and with such
other adjustments from time to time, as shall be equitable in order that all
Lenders share such payment in accordance with their respective ratable shares as
provided for in this Credit Agreement. Each Lender further agrees that if a
payment to a Lender (which is obtained by such Lender through the exercise of a
right of set-off, banker's lien, counterclaim or otherwise) shall be rescinded
or must otherwise be restored, each Lender which shall have shared the benefit
of such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit to each Lender whose payment shall have been rescinded
or otherwise restored. The Borrower agrees that any Lender so purchasing such a
participation may, to the fullest extent permitted by law, exercise all rights
of payment, including set-off, banker's lien or counterclaim, with respect to
such participation as fully as if such Lender were a holder of such Loan or
other obligation in the amount of such

                                       18

participation. Except as otherwise expressly provided in this Credit Agreement,
if any Lender shall fail to remit to the Administrative Agent or any other
Lender an amount payable by such Lender to the Administrative Agent or such
other Lender pursuant to this Credit Agreement on the date when such amount is
due, such payments shall accrue interest thereon, for each day from the date
such amount is due until the day such amount is paid to the Administrative Agent
or such other Lender, at a rate per annum equal to the Federal Funds Rate. If
under any applicable bankruptcy, insolvency or other similar law, any Lender
receives a secured claim in lieu of a setoff to which this Section 3.8 applies,
such Lender shall, to the extent practicable, exercise its rights in respect of
such secured claim in a manner consistent with the rights of the Lenders under
this Section 3.8 to share in the benefits of any recovery on such secured claim.

      3.9 EVIDENCE OF DEBT.

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

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

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

                                   SECTION 4.

                      ADDITIONAL PROVISIONS REGARDING LOANS

      4.1 EURODOLLAR LOAN PROVISIONS.

            (a) Unavailability. In the event that the Administrative Agent shall
      have determined in good faith (i) that U.S. dollar deposits in the
      principal amounts requested

                                       19


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

            (b) Change in Legality.

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

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

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

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

            (c) Requirements of Law. If at any time a Lender shall incur
      increased costs or reductions in the amounts received or receivable
      hereunder with respect to the making, the commitment to make or the
      maintaining of any Eurodollar Loan because of (i) any

                                       20


      change after the date hereof, in any law, governmental rule, regulation,
      guideline or order (including the introduction of any new law,
      governmental rule, regulation, guideline or order) or in the
      interpretation or administration thereof by any Governmental Authority
      charged with the interpretation or administration thereof, including,
      without limitation, the imposition, modification or deemed applicability
      of any reserves, deposits or similar requirements (such as, for example,
      but not limited to, a change in official reserve requirements, but, in all
      events, excluding reserves required under Regulation D to the extent
      included in the computation of the Adjusted Eurodollar Rate) or (ii) other
      circumstances affecting the London interbank Eurodollar market; then (A)
      the Lender shall promptly notify the Administrative Agent and the Borrower
      and shall designate a different lending office of such Lender if such
      designation will avoid or reduce the amount of such increased costs, or
      reductions in amounts receivable and such designation will not, in such
      Lender's sole discretion, be otherwise disadvantageous to such Lender and
      (B) the Borrower shall promptly pay to such Lender such additional amounts
      (in the form of an increased rate of, or a different method of
      calculating, interest or otherwise as such Lender may determine in its
      sole discretion) as may be required to compensate such Lender for such
      increased costs or reductions in amounts receivable hereunder.

      Each determination and calculation made by a Lender under this Section 4.1
shall, absent manifest error, be binding and conclusive on the parties hereto.
Any conversions of Eurodollar Loans made pursuant to this Section 4.1 shall
subject the Borrower to the payments required by Section 4.3. This Section 4.1
shall survive termination of this Credit Agreement and the other Credit
Documents and the payment of the Loans and all other amounts payable hereunder.

      4.2 CAPITAL ADEQUACY.

      If any Lender has determined in good faith that the adoption or
effectiveness, after the date hereof, of any applicable law, rule or regulation
regarding capital adequacy, or any change therein (after the date hereof), or
any change in the interpretation or administration thereof by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent corporation)
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such authority, central bank or comparable agency, has
or would have the effect of reducing the rate of return on such Lender's (or
parent corporation's) capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender (or its parent
corporation) could have achieved but for such adoption, effectiveness, change or
compliance (taking into consideration such Lender's (or parent corporation's)
policies with respect to capital adequacy), then, upon notice from such Lender,
the Borrower shall promptly pay to such Lender such additional amount or amounts
as will compensate such Lender for such reduction. Each determination by any
such Lender of amounts owing under this Section 4.2 shall, absent manifest
error, be conclusive and binding on the parties hereto. This Section 4.2 shall
survive termination of this Credit Agreement and the other Credit Documents and
the payment of the Loans and all other amounts payable hereunder.

                                       21


      4.3 COMPENSATION.

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

      4.4 TAXES.

            (a) Except as provided below in this Section 4.4, all payments made
      by the Borrower under this Credit Agreement and any Notes shall be made
      free and clear of, and without deduction or withholding for or on account
      of, any present or future income, stamp or other taxes, levies, imposts,
      duties, charges, fees, deductions or withholdings, now or hereafter
      imposed, levied, collected, withheld or assessed by any court, or
      governmental body, agency or other official, excluding taxes measured by
      or imposed upon the net income of any Lender or its applicable lending
      office, or any branch or affiliate thereof, and all franchise taxes,
      branch taxes, taxes on doing business or taxes on the capital or net worth
      of any Lender or its applicable lending office, or any branch or affiliate
      thereof, in each case imposed in lieu of net income taxes: (i) by the
      jurisdiction under the laws of which such Lender, applicable lending
      office, branch or affiliate is organized or is located, or in which its
      principal executive office is located, or any nation within which such
      jurisdiction is located or any political subdivision thereof; or (ii) by
      reason of any connection between the jurisdiction imposing such tax and
      such Lender, applicable lending office, branch or affiliate other than a
      connection arising solely from such Lender having executed, delivered or
      performed its obligations, or received payment under or enforced, this
      Credit Agreement or any Notes. If any such non-excluded taxes, levies,
      imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded
      Taxes") are required to be withheld from any amounts payable to an
      Administrative Agent or any Lender hereunder or under any Notes, (A) the
      amounts so payable to the Administrative Agent or such Lender shall be
      increased to the extent necessary to yield to the Administrative Agent or
      such Lender (after payment of all Non-Excluded Taxes) interest or any such
      other amounts payable hereunder at the rates or in the amounts specified
      in this Credit Agreement and any Notes, provided, however, that the
      Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes
      and shall not be required to increase any such amounts payable to any
      Lender that is not organized under the laws of the United States of
      America or a state thereof if such Lender fails to comply with the
      requirements of paragraph (b) of this Section 4.4 whenever any
      Non-Excluded

                                       22


      Taxes are payable by the Borrower, and (B) as promptly as possible after
      requested, the Borrower shall send to the Administrative Agent for its own
      account or for the account of such Lender, as the case may be, a certified
      copy of an original official receipt received by the Borrower showing
      payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when
      due to the appropriate taxing authority or fails to remit to the
      Administrative Agent the required receipts or other required documentary
      evidence, the Borrower shall indemnify the Administrative Agent and any
      Lender for any incremental Non-Excluded Taxes, interest or penalties that
      may become payable by the Administrative Agent or any Lender as a result
      of any such failure. The agreements in this Section 4.4 shall survive the
      termination of this Credit Agreement and the payment of the Loans and all
      other amounts payable hereunder.

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

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

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

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

                  (ii) in the case of any such Lender that is not a "bank"
            within the meaning of Section 881(c)(3)(A) of the Internal Revenue
            Code, (A) represent to the Borrower (for the benefit of the Borrower
            and the Administrative Agent) that it is not a bank within the
            meaning of Section 881 (c)(3)(A) of the Internal Revenue Code, (B)
            agree to furnish to the Borrower, on or before the date of any
            payment by the Borrower, with a copy to the Administrative Agent,
            two accurate and complete original signed copies of Internal Revenue
            Service Form W-8, or successor applicable form certifying to such
            Lender's legal entitlement at the date of such certificate to an
            exemption from U.S. withholding tax under the provisions of Section
            881(c) of the Internal Revenue Code with respect to payments to be
            made under this Credit Agreement and any Notes (and to deliver to
            the Borrower and the Administrative Agent two further copies of such
            form on

                                       23


            or before the date it expires or becomes obsolete and after the
            occurrence of any event requiring a change in the most recently
            provided form and, if necessary, obtain any extensions of time
            reasonably requested by the Borrower or the Administrative Agent for
            filing and completing such forms), and (C) agree, to the extent
            legally entitled to do so, upon reasonable request by the Borrower,
            to provide to the Borrower (for the benefit of the Borrower and the
            Administrative Agent) such other forms as may be reasonably required
            in order to establish the legal entitlement of such Lender to an
            exemption from withholding with respect to payments under this
            Credit Agreement and any Notes.

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

in compliance would not have or would not reasonably be expected to have a

      Neither the Borrower nor any of its Subsidiaries is in default in any
respect under any contract, lease, loan agreement, indenture, mortgage, security

      condition has occurred or exists as a result of which any Termination

      a Plan has arisen or is reasonably expected to arise on account of any
      Plan.

            (b) No liability has been or is reasonably expected by the Borrower

      under Sections 406, 407, 409, 502(i), or 502(l) of ERISA or Section 4975
      of the Code, or under any agreement or other instrument pursuant to which
      the Borrower or any ERISA Affiliate has agreed or is required to indemnify
      any person against any such liability.

            (f) The present value (determined using actuarial and other
      assumptions which are reasonable with respect to the benefits provided and
      the employees participating) of the liability of the Borrower and each
      ERISA Affiliate for post-retirement welfare benefits to be provided to
      their current and former employees under Plans which are welfare benefit
      plans (as defined in Section 3(1) of ERISA), net of all assets under all
      such Plans allocable to such benefits, are reflected on the financial

      6.14 USE OF PROCEEDS.

      The proceeds of the Loans hereunder will be used solely for the purposes

acquisition.

      6.15 GOVERNMENT REGULATION.

            (a) No proceeds of the Loans will be used, directly or indirectly,
      for the purpose of purchasing or carrying any "margin stock" within the

      trading in any securities. If requested by any Lender or the
      Administrative Agent, the Borrower will furnish to the Administrative
      Agent and each Lender a statement to the foregoing effect in conformity
      with the requirements of FR Form U-1 referred to in Regulation U. No
      indebtedness being reduced or retired out of the proceeds of the Loans was

      stock within the meaning of Regulation U or any "margin security" within
      the meaning of Regulation T. "Margin stock" within the meaning of
      Regulation U does not constitute more than 25% of the value of the
      consolidated assets of the Borrower and its Subsidiaries. None of the
      transactions contemplated by the Credit Documents (including, without
      limitation, the direct or indirect use of the proceeds of the Loans) will
      violate or result in a violation of the Securities Act or the Exchange
      Act.

      "investment company" registered or required to be registered under the
      Investment Company Act of 1940, as amended, and is not controlled by an
      "investment company", or (ii) a "holding

                                       30


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

            (c) No director, executive officer or principal shareholder of the
      Borrower or any of its Subsidiaries is a director, executive officer or
      principal shareholder of any Lender. For the purposes hereof the terms
      "director", "executive officer" and "principal shareholder" (when used
      with reference to any Lender) have the respective meanings assigned
      thereto in Regulation O.

      6.16 DISCLOSURE.

      Neither this Credit Agreement nor any financial statements delivered to
the Lenders nor any other document, certificate or statement furnished to the
Lenders by or on behalf of the Borrower in connection with the transactions
contemplated hereby contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained
therein or herein, taken as a whole, not misleading.

reputable insurance companies or associations in such amounts and covering such
risks as is usually carried by companies engaged in similar business and owning
similar properties in the same general areas in which the Borrower and its
Subsidiaries operate.

      The Borrower and its Subsidiaries possess (a) good title to, or the legal
right to use, all material properties and assets and (b) all material

case as are necessary for the operation of their respective businesses.

franchises and authority, except where failure to do so would not or would not
reasonably be expected to have a Material Adverse Effect. The Borrower will, and
will cause its Subsidiaries to, generally maintain its properties, real and
personal, in good condition, and the Borrower and its Subsidiaries shall not
waste or otherwise permit such properties to deteriorate, reasonable wear and

assessment, charge, levy, claim or indebtedness which is being contested in good

adequate reserves therefor, if required, have been established in accordance
with GAAP, unless the failure to make any such payment (i) would give rise to an
immediate right to foreclose or collect on a Lien securing such amounts or (ii)
would have or would reasonably be expected to have a Material Adverse Effect.

      payment (beyond the applicable grace period with respect thereto, if any)
      with respect to any such indebtedness, or (2) default (after giving effect
      to any applicable grace period) in the observance or performance of any
      covenant or agreement relating to such indebtedness or contained in any
      instrument or agreement evidencing, securing or relating thereto, or any
      other event or condition shall occur or condition exist, the effect of
      which default or other event or condition is to cause, or permit, the
      holder of the holders of such indebtedness (or trustee or agent on behalf

      or lapse of time is required) any such indebtedness to become due prior to

      and payable, or required to be prepaid other than by a regularly scheduled
      required prepayment prior to the stated maturity thereof; or (C) any such
      indebtedness shall mature and remain unpaid.

            (g) Judgments. One or more judgments, orders, or decrees shall be

      by a carrier who has acknowledged coverage) and such judgments, orders or
      decrees shall continue unsatisfied, undischarged and unstayed for a period
      ending on the first to occur of (i) the last day on which such judgment,
      order or decree becomes final and unappealable and, where applicable, with

      such periodic payment.

            (h) ERISA. The occurrence of any of the following events or
      conditions if any of the same would be reasonably expected to result in a
      liability of an amount greater than or equal to $20,000,000: (A) any
      "accumulated funding deficiency," as such term is defined in Section 302
      of ERISA and Section 412 of the Code, whether or not waived, shall exist
      with respect to any Plan, or any lien shall arise on the assets of the
      Borrower or any ERISA Affiliate in favor of the PBGC or a Plan; (B) a
      Termination Event shall occur with respect to a Single Employer Plan,
      which is, in the reasonable opinion of the Administrative Agent, likely to
      result in the termination of such Plan for purposes of Title IV of ERISA;
      (C) a Termination Event shall occur with respect to a Multiemployer Plan
      or Multiple Employer Plan, which is, in the reasonable opinion of the
      Administrative Agent, likely to result in (i) the termination of such Plan
      for purposes of Title IV of ERISA, or (ii) the Borrower or any ERISA
      Affiliate incurring any liability in connection with a withdrawal from,
      reorganization of (within the meaning of Section 4241 of ERISA), or
      insolvency (within the meaning of Section 4245 of ERISA) of such Plan; or
      (D) any prohibited transaction (within the meaning of Section 406 of ERISA
      or Section

                                       39


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

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

      9.2 ACCELERATION; REMEDIES.

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

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

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

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

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

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

      9.3 ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

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

            FIRST, to the payment of all reasonable out-of-pocket costs and
      expenses (including without limitation reasonable attorneys' fees) of the
      Administrative Agent or

                                       40


      any of the Lenders in connection with enforcing the rights of the
      Lenders under the Credit Documents, pro rata as set forth below;

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

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

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

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

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

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

                                  SECTION 10.

                                AGENCY PROVISIONS

      10.1 APPOINTMENT.

      Each Lender hereby designates and appoints Bank One, NA as agent of such
Lender to act as specified herein and the other Credit Documents, and each such
Lender hereby authorizes the Administrative Agent, as the agent for such Lender,
to take such action on its behalf under the provisions of this Credit Agreement
and the other Credit Documents and to exercise such powers and perform such
duties as are expressly delegated by the terms hereof and of the other Credit
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere herein and in the other
Credit Documents, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Credit Agreement or any of the other Credit Documents, or shall otherwise exist
against the Administrative Agent. The provisions of this Section 10.1 are solely
for the benefit of the Administrative Agent and the Lenders and the Borrower
shall not have any rights as a third party beneficiary of the provisions hereof.
In performing its functions and duties under this Credit Agreement and the other
Credit Documents, the Administrative Agent shall act solely as agent of the
Lenders and does not assume and shall not be deemed to have assumed any
obligation or relationship of agency or trust with or for the Borrower. Any
agent named herein (other than the

                                       41


Administrative Agent) shall have no duties or obligations whatsoever under this
Credit Agreement or the other Credit Documents.

      10.2 DELEGATION OF DUTIES.

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

      10.3 EXCULPATORY PROVISIONS.

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

      10.4 RELIANCE ON COMMUNICATIONS.

      The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it in
good faith to be genuine and correct and to have been signed, sent or made by
the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrower, independent accountants
and other experts selected by the Administrative Agent with reasonable care).
The Administrative Agent may deem and treat the Lenders as the owner of its
interests hereunder for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Administrative
Agent in

                                       42


accordance with Section 11.3(b). The Administrative Agent shall be fully
justified in failing or refusing to take any action under this Credit Agreement
or under any of the other Credit Documents unless it shall first receive such
advice or concurrence of the Required Lenders as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder or under
any of the other Credit Documents in accordance with a request of the Required
Lenders (or to the extent specifically provided in Section 11.6, all the
Lenders) and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders (including their successors and
assigns).

      10.5 NOTICE OF DEFAULT.

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

                                       43


      10.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

      Each Lender expressly acknowledges that neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representations or warranties to it and that no act by
the Administrative Agent or any affiliate thereof hereinafter taken, including
any review of the affairs of the Borrower, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender. Each
Lender represents to the Administrative Agent that it has, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrower
and made its own decision to make its Extensions of Credit hereunder and enter
into this Credit Agreement. Each Lender also represents that it will,
independently and without reliance upon the Administrative Agent or any other
Lender, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Credit Agreement, and to make such
investigation as it deems necessary to inform itself as to the business, assets,
operations, property, financial and other conditions, prospects and
creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, assets, property, financial or other
conditions, prospects or creditworthiness of the Borrower which may come into
the possession of the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates.

      10.7 INDEMNIFICATION.

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

                                       44


      10.8 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

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

      10.9 SUCCESSOR AGENT.

      The Administrative Agent may, at any time, resign upon 20 days written
notice to the Lenders. Upon any such resignation, the Required Lenders shall
have the right to appoint a successor Administrative Agent, which successor
shall be reasonably acceptable to the Borrower; provided that the Borrower shall
have no right to approve such successor during the existence and continuation of
a Default or Event of Default. If no successor Administrative Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the notice of resignation, then the retiring
Administrative Agent shall select a successor Administrative Agent; provided
such successor is an Eligible Assignee (or if no Eligible Assignee shall have
been so appointed by the retiring Administrative Agent and shall have accepted
such appointment, then the Lenders shall perform all obligations of the retiring
Administrative Agent hereunder until such time, if any, as a successor
Administrative Agent shall have been appointed and shall have accepted such
appointment as provided for above). Upon the acceptance of any appointment as an
Administrative Agent hereunder by a successor, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations as an
Administrative Agent, as appropriate, under this Credit Agreement and the other
Credit Documents and the provisions of this Section 10 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was an
Administrative Agent under this Credit Agreement.

      11.2 RIGHT OF SET-OFF.

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

      11.3 BENEFIT OF AGREEMENT.

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

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

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

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

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

                                       46


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

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

            By executing and delivering an assignment agreement in accordance
      with this Section 11.3(b), the assigning Lender thereunder and the
      assignee thereunder shall be deemed to confirm to and agree with each
      other and the other parties hereto as follows: (A) such assigning Lender
      warrants that it is the legal and beneficial owner of the interest being
      assigned thereby free and clear of any adverse claim created by such
      assigning Lender and the assignee warrants that it is an Eligible
      Assignee; (B) except as set forth in clause (A) above, such assigning
      Lender makes no representation or warranty and assumes no responsibility
      with respect to any statements, warranties or representations made in or
      in connection with this Credit Agreement, any of the other Credit
      Documents or any other instrument or document furnished pursuant hereto or
      thereto, or the execution, legality, validity, enforceability,
      genuineness, sufficiency or value of this Credit Agreement, any of the
      other Credit Documents or any other instrument or document furnished
      pursuant hereto or thereto or the financial condition of the Borrower or
      the performance or observance by the Borrower of any of its obligations
      under this Credit Agreement, any of the other Credit Documents or any
      other instrument or document furnished pursuant hereto or thereto; (C)
      such assignee represents and warrants that it is legally authorized to
      enter into such assignment agreement; (D) such assignee confirms that it
      has received a copy of this Credit Agreement, the other Credit Documents
      and such other documents and information as it has deemed appropriate to
      make its own credit analysis and decision to enter into such assignment
      agreement; (E) such assignee will independently and without reliance upon
      the Administrative Agent, such assigning Lender or any other Lender, and
      based on such documents and information as it shall deem appropriate at
      the time, continue to make its own credit decisions in taking or not
      taking action under this Credit Agreement and the other Credit Documents;
      (F) such assignee appoints and authorizes the Administrative Agent to take
      such action on its behalf and to exercise such powers under this Credit
      Agreement or any other Credit Document as are delegated to the
      Administrative Agent by the terms hereof or thereof, together with such
      powers as are reasonably incidental thereto; and (G) such assignee agrees
      that it will perform in accordance with their terms all the obligations

                                       47


      which by the terms of this Credit Agreement and the other Credit Documents
      are required to be performed by it as a Lender.

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

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

            (e) Participations. Each Lender may sell participations to one or
      more Persons in all or a portion of its rights, obligations or rights and
      obligations under this Credit Agreement (including all or a portion of its
      Commitment, its Notes and its Loans); provided, however, that (i) such
      Lender's obligations under this Credit Agreement shall remain unchanged,
      (ii) such Lender shall remain solely responsible to the other parties
      hereto for the performance of such obligations, (iii) the participant
      shall be entitled to the benefit of the yield protection provisions
      contained in Sections 4.1 through 4.4, inclusive, and the right of set-off
      contained in Section 11.2, and (iv) the Borrower shall continue to deal
      solely and directly with such Lender in connection with such Lender's
      rights and obligations under this Credit Agreement, and such Lender shall
      retain the sole right to enforce the obligations of the Borrower relating
      to its Loans and its Notes and to approve any amendment, modification, or
      waiver of any provision of this Credit Agreement (other than amendments,
      modifications, or waivers decreasing the amount of principal of or the
      rate at which interest is payable on such Loans or Notes, extending any
      scheduled principal payment date or date fixed for the payment of interest
      on such Loans or Notes, or extending its Commitment).

            (f) Nonrestricted Assignments. Notwithstanding any other provision
      set forth in this Credit Agreement, any Lender may at any time assign and
      pledge all or any portion of its Loans and its Notes to any Federal
      Reserve Bank as collateral security pursuant to Regulation A and any
      Operating Circular issued by such Federal Reserve Bank. No such assignment
      shall release the assigning Lender from its obligations hereunder.

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

                                       48


      11.4 NO WAIVER; REMEDIES CUMULATIVE.

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

      11.5 PAYMENT OF EXPENSES, ETC.

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

      11.6 AMENDMENTS, WAIVERS AND CONSENTS.

      Neither this Credit Agreement, nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or

                                       49


amendment, change, waiver, discharge or termination is in writing and signed by
the Required Lenders and the Borrower; provided that no such amendment, change,
waiver, discharge or termination shall without the consent of each Lender
affected thereby:

      payment or prepayment of principal;

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

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

            (d) increase or extend the Commitment of a Lender (it being
      understood and agreed that a waiver of any Default or Event of Default or

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

            (f) amend, modify or waive any provision of this Section 11.6 or

certain circumstances as set forth above, each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans, and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy

      11.7 COUNTERPARTS/TELECOPY.

      This Credit Agreement may be executed in any number of counterparts, each
of which where so executed and delivered shall be an original, but all of which

representation that an original will be delivered.

      11.8 HEADINGS.

                                       51

      11.12 WAIVER OF JURY TRIAL.

      EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES ALL

TRANSACTIONS CONTEMPLATED HEREBY.

      11.13 SEVERABILITY.

      If any provision of any of the Credit Documents is determined to be

      11.16 BINDING EFFECT; CONTINUING AGREEMENT.

      shall be binding upon and inure to the benefit of the Borrower, the
      Administrative Agent and each Lender and their respective successors and
      assigns. The Borrower and the Lenders party to the Existing Credit
      Agreement each hereby agrees that, at such time as this Credit Agreement
      shall have become effective pursuant to the terms of the immediately
      preceding sentence, the Existing Credit Agreement automatically shall be
      deemed terminated and the Borrowers and the Lenders party to the Existing
      Credit Agreement shall no longer have any obligations thereunder (other
      than those obligations in the Existing Credit Agreement that expressly
      survive the termination thereof).

                                       52

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