         (b) The Borrower agrees to pay to the Administrative Agent the fees in
the amounts and on the dates from time to time agreed to in writing by the
Borrower and the Administrative Agent.

         2.5 Termination or Reduction of Revolving Commitments. The Borrower
shall have the right, upon not less than three Business Days' notice to the
Administrative Agent, to terminate any of the Revolving Commitments or, from
time to time, to reduce the amount of any of the Revolving Commitments;
provided, that no such termination or reduction of Revolving Commitments shall
be permitted if, after giving effect thereto and to any prepayments of the Loans
made on the effective date thereof, the Total Revolving Extensions of Credit
would exceed the Total Revolving Commitments. Any such reduction shall be in a
minimum amount equal to $5,000,000, or a whole multiple of $1,000,000 in excess
thereof (or, if the then aggregate Revolving Commitments are less than
$5,000,000, such lesser amount), and shall reduce permanently the relevant
Revolving Commitments then in effect.

         2.6 Optional Prepayments. The Borrower may at any time and from time to
time prepay the Loans, in whole or in part, without premium or penalty, upon
irrevocable notice delivered to the Administrative Agent at least three Business
Days prior thereto in the case of Eurodollar Loans and, prior to 11:00 a.m.,
Central Time, on the date of such prepayment in the

                                       20
<PAGE>   26

case of Base Rate Loans, which notice shall specify the date and amount of
prepayment and whether the prepayment is of Eurodollar Loans or Base Rate Loans;
provided, that if a Eurodollar Loan is prepaid on any day other than the last
day of the Interest Period applicable thereto, the Borrower shall also pay any
amounts owing pursuant to subsection 2.16. Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof. If any
such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with (except in the case of Base
Rate Loans) accrued interest to such date on the amount prepaid. Partial
prepayments of Loans shall be in an aggregate principal amount of $1,000,000 or
a whole multiple thereof (or if the then aggregate principal amount of Loans
outstanding is less than $1,000,000, such lesser amount).

         2.7 Mandatory Commitment Termination and Prepayment upon Change of
Control. Upon the occurrence of a Change of Control, (a) automatically, without
any notice, the Revolving Commitments shall immediately terminate and (b) the
Borrower shall immediately prepay all Loans, together with all accrued and
unpaid interest thereon and shall immediately cash collateralize all outstanding
L/C Obligations in the manner contemplated by the last paragraph of Section 8.

         2.8 Conversion and Continuation Options. (a) The Borrower may elect
from time to time to convert Eurodollar Loans to Base Rate Loans by giving the
Administrative Agent at least one Business Day's prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert Base Rate Loans to Eurodollar Loans by
giving the Administrative Agent at least three Business Days' prior irrevocable
notice of such election (which notice shall specify the length of the initial
Interest Period therefore), provided, that no Base Rate Loan may be converted
into a Eurodollar Loan (i) when any Event of Default has occurred and is
continuing and the Administrative Agent or the Majority Lenders have determined
in its or their sole discretion not to permit such conversions or (ii) after the
date that is one month prior to the Revolving Termination Date. Upon receipt of
any such notice, the Administrative Agent shall promptly notify each Lender
thereof.

         (b) Any Eurodollar Loan may be continued as such upon the expiration of
the then current Interest Period with respect thereto by the Borrower giving
irrevocable notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection 1.1,
of the length of the next Interest Period to be applicable to such Loans,
provided, that no Eurodollar Loan may be continued as such (i) when any Event of
Default has occurred and is continuing and the Administrative Agent has or the
Majority Lenders have determined in its or their sole discretion not to permit
such continuations or (ii) after the date that is one month prior to the
Revolving Termination Date, and provided, further, that if the Borrower shall
fail to give any required notice as described above in this paragraph or if such
continuation is not permitted pursuant to the preceding proviso such Loans shall
be automatically converted to Base Rate Loans on the last day of such then
expiring Interest Period. Upon receipt of any such notice, the Administrative
Agent shall promptly notify each relevant Lender thereof.

                                       21
<PAGE>   27

         2.9 Minimum Amounts and Maximum Number of Eurodollar Tranches.
Notwithstanding anything to the contrary in this Agreement, all borrowings,
conversions, continuations and optional prepayments of Eurodollar Loans
hereunder and all selections of Interest Periods hereunder shall be in such
amounts and be made pursuant to such elections so that, (a) after giving effect
thereto, the aggregate principal amount of the Eurodollar Loans comprising each
Eurodollar Tranche shall be equal to $1,000,000 or a whole multiple of
$1,000,000 in excess thereof and (b) no more than six Eurodollar Tranches shall
be outstanding at any one time.

         2.10 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall
bear interest for each day during each Interest Period with respect thereto at a
rate per annum equal to the Eurodollar Rate determined for such Interest Period
plus the Applicable Margin.

         (b) Each Base Rate Loan shall bear interest at a rate per annum equal
to the Base Rate plus the Applicable Margin.

         (c) (i) If all or a portion of the principal amount of any Loan or
Reimbursement Obligation shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is equal to (x) in the case of the Loans, the rate
that would otherwise be applicable thereto pursuant to the foregoing provisions
of this subsection 2.10 plus 2% or (y) in the case of Reimbursement Obligations,
the rate applicable to Base Rate Loans plus 2%, and (ii) if all or a portion of
any interest payable on any Loan or Reimbursement Obligation or any commitment
fee or other amount payable hereunder shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum equal to the rate then applicable to Base Rate
Loans plus 2%, in each case, with respect to clauses (i) and (ii) above, from
the date of such non-payment until such amount is paid in full (as well after as
before judgment).

         (d) Interest shall be payable in arrears on each Interest Payment Date,
provided that interest accruing pursuant to paragraph (c) of this subsection
2.10 shall be payable from time to time on demand.

         2.11 Computation of Interest and Fees. (a) Interest, fees and
commissions payable pursuant hereto shall be calculated on the basis of a
360-day year for the actual days elapsed, except that, with respect to Base Rate
Loans the rate of interest on which is calculated on the basis of the Prime
Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-,
as the case may be) day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the Borrower and the Lenders of each
determination of a Eurodollar Rate. Any change in the interest rate on a Loan
resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective. The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of the effective date and the
amount of each such change in interest rate.

                                       22
<PAGE>   28

         (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to subsection 2.10(a).

         2.12 Inability to Determine Interest Rate. If prior to the first day of
any Interest Period:

         (a) the Administrative Agent shall have determined in good faith (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Eurodollar Rate for such Interest Period, or

         (b) the Administrative Agent shall have received notice from the
Majority Lenders that the Eurodollar Rate determined or to be determined for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders (as conclusively certified by such Lenders) of making or maintaining
their affected Loans during such Interest Period,

then the Administrative Agent shall give telecopy or telephonic notice thereof
to the Borrower and the relevant Lenders as soon as practicable thereafter. If
such notice is given (x) any Eurodollar Loans requested to be made on the first
day of such Interest Period shall be made as Base Rate Loans, (y) any Loans that
were to have been converted on the first day of such Interest Period to
Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding
Eurodollar Loans shall be converted, on the last day of the Interest Period then
in effect with respect to such Eurodollar Loans, to Base Rate Loans. Until such
notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans shall be made or continued as such, nor shall the Borrower have the right
to convert Loans to Eurodollar Loans.

         2.13 Pro Rata Treatment and Payments. (a) Each borrowing by the
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee and any reduction of the Revolving Commitments of the Lenders
shall be made pro rata according to the Revolving Percentages of the Lenders.
Each payment (including prepayments) in respect of principal or interest in
respect of the Loans, each payment in respect of fees payable hereunder, and
each payment in respect of Reimbursement Obligations, shall be applied to the
amounts of such obligations owing to the Lenders pro rata according to the
respective amounts then due and owing to the Lenders.

         (b) All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
Central Time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Payment Office, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received. If any payment
hereunder (other than payments on the Eurodollar Loans) becomes due and payable
on a day other than a Business Day, such payment shall be extended to the next
succeeding Business Day.

                                       23
<PAGE>   29

If any payment on a Eurodollar Loan becomes due and payable on a day other than
a Business Day, the maturity thereof shall be extended to the next succeeding
Business Day unless the result of such extension would be to extend such payment
into another calendar month, in which event such payment shall be made on the
immediately preceding Business Day. In the case of any extension of any payment
of principal pursuant to the preceding two sentences, interest thereon shall be
payable at the then applicable rate during such extension.

         (c) Unless the Administrative Agent shall have been notified in writing
by any Lender prior to a borrowing that such Lender will not make the amount
that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefore, such Lender shall
pay to the Administrative Agent, on demand, such amount with interest thereon at
a rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum equal to the
daily average Federal Funds Effective Rate, on demand, from the Borrower.

         (d) Unless the Administrative Agent shall have been notified in writing
by the Borrower prior to the date of any payment being made hereunder that the
Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

         2.14 Requirements of Law (a) If the adoption of or any change in any
Requirement of Law (exclusive of any organizational or governance document of
any Lender or Agent) or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

          (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Letter of Credit, any Application or any
     Eurodollar Loan made by it, or change the basis of taxation of payments to
     such Lender in respect thereof (except for

                                       24
<PAGE>   30

     Non-Excluded Taxes covered by subsection 2.15 and changes in the rate of
     tax on the overall net income of such Lender);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

          (iii) shall impose on such Lender any other condition; and the result
     of any of the foregoing is to increase the cost to such Lender, by an
     amount which such Lender deems to be material, of making, converting into,
     continuing or maintaining Eurodollar Loans or issuing or participating in
     Letters of Credit, or to reduce any amount receivable hereunder in respect
     thereof,

then, in any such case, the Borrower shall promptly pay such Lender, upon its
demand, any additional amounts necessary to compensate such Lender for such
increased cost or reduced amount receivable. If any Lender becomes entitled to
claim any additional amounts pursuant to this subsection 2.14, it shall promptly
notify the Borrower (with a copy to the Administrative Agent) of the event by
reason of which it has become so entitled.

         (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law (exclusive of any organizational or governance
document of any Lender or Agent) regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefore, the Borrower shall pay to such Lender
such additional amount or amounts as will compensate such Lender for such
reduction.

         (c) A certificate as to any additional amounts payable pursuant to this
subsection 2.14 submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
obligations of the Borrower pursuant to this subsection 2.14 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

         2.15 Taxes. (a) All payments made by the Borrower under this Agreement
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

                                       25
<PAGE>   31

Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on any Agent or any Lender as a result of a
present or former connection between such Agent or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision or taxing authority thereof or therein (other than any such
connection arising solely from such Agent or such Lender having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement or any other Loan Document). If any such non-excluded taxes,
levies, imposts, duties, charges, fees, deductions or withholdings
("Non-Excluded Taxes") or Other Taxes are required to be withheld from any
amounts payable to any Agent or any Lender hereunder, the amounts so payable to
such Agent or such Lender shall be increased to the extent necessary to yield to
such Agent or such Lender (after payment of all Non-Excluded Taxes and Other
Taxes) interest or any such other amounts payable hereunder at the rates or in
the amounts specified in this Agreement, provided, however, that the Borrower
shall not be required to increase any such amounts payable to any Lender with
respect to any Non-Excluded Taxes (i) that are attributable to such Lender's
failure to comply with the requirements of paragraph (d) or (e) of this
subsection 2.15 or (ii) that are United States withholding taxes imposed on
amounts payable to such Lender at the time the Lender becomes a party to this
Agreement, except to the extent that such Lender's assignor (if any) was
entitled, at the time of assignment, to receive additional amounts from the
Borrower with respect to such Non-Excluded Taxes pursuant to this subsection
2.15(a).

         (b) In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

         (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the
Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for the account of the relevant Agent or Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof or other evidence of payment thereof
satisfactory to the Administrative Agent. If the Borrower fails to pay any
Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority
or fails to remit to the Agents the required receipts or other required
documentary evidence, the Borrower shall indemnify the Administrative Agent and
the Lenders for any incremental taxes, interest or penalties that may become
payable by any Agent or any Lender as a result of any such failure. The
agreements in this subsection 2.15 shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

         (d) Each Lender (or Transferee) that is not a citizen or resident of
the United States of America, a corporation, partnership or other entity created
or organized in or under the laws of the United States of America (or any
jurisdiction thereof), or any estate or trust that is subject to federal income
taxation regardless of the source of its income (a "Non-U.S. Lender") shall
deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or
Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S.
federal withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest" a statement substantially in the form of
Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors
thereto

                                       26
<PAGE>   32

properly completed and duly executed by such Non-U.S. Lender claiming complete
exemption from, or a reduced rate of, U.S. federal withholding tax on all
payments by the Borrower under this Agreement and the other Loan Documents. 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 any Participant, on or
before the date such Participant purchases the related participation). 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. Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

         (e) A Lender that is entitled to an exemption from or reduction of
non-U.S. withholding tax under the law of the jurisdiction in which the Borrower
is located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law or
reasonably requested by the Borrower, such properly completed and executed
documentation prescribed by applicable law as will permit such payments to be
made without withholding or at a reduced rate, provided that such Lender is
legally entitled to complete, execute and deliver such documentation and in such
Lender's reasonable judgment such completion, execution or submission would not
materially prejudice the legal position of such Lender.

         2.16 Indemnity. The Borrower agrees 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 making a borrowing
of, conversion into or continuation of Eurodollar Loans after the Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by the Borrower in making any prepayment after the
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto. Such
indemnification may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar
market. A certificate as to any amounts payable pursuant to this subsection 2.16
submitted to the Borrower by any Lender shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                                       27
<PAGE>   33

         2.17 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law (exclusive of any
organizational or governance document of any Lender or Agent) or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be cancelled and (b) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to subsection
2.16.

         2.18 Change of Lending Office. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of subsection 2.14, 2.15(a)
or 2.17 with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this subsection 2.18 shall
affect or postpone any of the obligations of any Borrower or the rights of any
Lender pursuant to subsection 2.14, 2.15(a) or 2.17.

         2.19 Extension of Revolving Termination Date. (a) The Borrower may, by
written notice to the Administrative Agent (such notice being an "Extension
Notice") given no earlier than ninety days and no later than fifteen Business
Days prior to an anniversary of the Closing Date, request the Lenders to
consider an extension of the then applicable Revolving Termination Date to a
date one year after the then applicable Revolving Termination Date. The
Administrative Agent shall promptly transmit any Extension Notice to each
Lender. Each Lender shall notify the Administrative Agent whether it wishes to
extend the then applicable Revolving Termination Date no later than ten Business
Days after receipt by it of any such Extension Notice, and any such notice given
by a Lender to the Administrative Agent, once given, shall be irrevocable as to
such Lender. Any Lender which does not expressly notify the Administrative Agent
prior to such ten-day period that it wishes to so extend the then applicable
Revolving Termination Date shall be deemed to have rejected the Borrower's
request for extension of such Revolving Termination Date. Lenders consenting to
extend the then applicable Revolving Termination Date are hereinafter referred
to as "Continuing Lenders", and Lenders declining to consent to extend such
Revolving Termination Date (or Lenders deemed to have so declined) are
hereinafter referred to as "Non- Extending Lenders". If Lenders holding not less
than 80% of the Revolving Commitments then in effect have elected (in their sole
and absolute discretion) to so extend the Revolving Termination Date, the
Administrative Agent shall notify the Borrower of such election by such Lenders,
and effective on the date of such notice by the Administrative Agent to the
Borrower, the Revolving Termination Date shall be automatically and immediately
so extended with respect to all Continuing Lenders. Upon the delivery of an
Extension Notice and upon the extension of the Revolving Termination Date

                                       28
<PAGE>   34

pursuant to this subsection, the Borrower shall be deemed to have represented
and warranted on and as of the date of such Extension Notice and the effective
date of such extension, as the case may be, that no Default or Event of Default
has occurred and is continuing. Notwithstanding anything contained in this
Agreement to the contrary, no Lender shall have any obligation to extend the
Revolving Termination Date, and each Lender may at its option, unconditionally
and without cause, decline to extend the Revolving Termination Date.

         (b) If the Revolving Termination Date shall have been extended in
accordance with this subsection, all references herein to the "Revolving
Termination Date" shall refer to the Revolving Termination Date as so extended.

         (c) If any Lender shall determine not to extend the Revolving
Termination Date as requested by any Extension Notice given by the Borrower
pursuant to this subsection, the Revolving Commitment of such Lender shall
terminate on the Revolving Termination Date without giving any effect to such
proposed extension, and the Borrower shall on such date pay to the
Administrative Agent, for the account of such Lender, the principal amount of,
and accrued interest on, such Lender's Loans, together with any amounts payable
to such Lender pursuant to Sections 2.14, 2.15 and 2.16 and any fees or other
amounts owing to such Lender under this Agreement; provided that if such
Non-Extending Lender has been replaced pursuant to paragraph (d) below then the
provisions of such paragraph (d) shall apply. The Total Revolving Commitment
shall be reduced by the amount of the Revolving Commitment of such Non-Extending
Lender to the extent the Revolving Commitment of such Non-Extending Lender has
not been transferred to one or more Continuing Lenders pursuant to paragraph (d)
below.

         (d) A Non-Extending Lender shall be obligated, at the request of the
Borrower and subject to payment by the Borrower to the Administrative Agent, for
the account of such Non-Extending Lender, of the principal amount of, and
accrued interest on, such Lender's Loans, together with any amounts payable to
such Lender pursuant to Sections 2.14, 2.15 and 2.16 and any fees or other
amounts owing to such Lender under this Agreement, to transfer without recourse,
representation, warranty (other than good title to its Loans) or expense to such
Non-Extending Lender, at any time prior to the Revolving Termination Date
applicable to such Non-Extending Lender, all of its rights (except those which
by their terms survive termination) and obligations hereunder to another
financial institution or group of financial institutions selected by the
Borrower in consultation with the Administrative Agent and willing to
participate in the facility in the place of such Non-Extending Lender; provided
that, if such transferee is not a Lender, such transferee(s) satisfies all the
requirements of this Agreement and the Administrative Agent and the Borrower
each shall have consented to such transfer, which consent shall not be
unreasonably withheld. Each such transferee shall become a Continuing Lender
hereunder in replacement of the Non-Extending Lender and shall enjoy all rights
and assume all obligations on the part of the Lenders set forth in this
Agreement. Simultaneously with such transfer, each such transferee shall execute
and deliver to the Administrative Agent an Assignment and Acceptance assuming
all obligations of the Lenders set forth in this Agreement.

         (e) If the Revolving Termination Date shall have been extended in
respect of Continuing Lenders in accordance with Section 2.19(a), any notice of
borrowing pursuant to

                                       29
<PAGE>   35

Section 2.2 specifying a Borrowing Date occurring after the Revolving
Termination Date applicable to a Non-Extending Lender or requesting an Interest
Period extending beyond such date shall (a) have no effect in respect of such
Non-Extending Lender and (b) not specify a requested aggregate principal amount
exceeding the aggregate Available Revolving Commitment (calculated on the basis
of the Revolving Commitments of the Continuing Lenders).

                          SECTION 3. LETTERS OF CREDIT

         3.1 L/C Commitment. (a) Pursuant to the Existing Credit Agreement, Bank
One, NA, as issuing lender thereunder, has issued the Letters of Credit
described in Schedule 3.1 (the "Existing Letters of Credit"). From and after the
Closing Date, the Existing Letters of Credit shall constitute "Letters of
Credit" hereunder. Subject to the terms and conditions hereof and in reliance on
the agreements of the other Lenders set forth in subsection 3.4(a), each Issuing
Lender agrees to issue letters of credit (together with the Existing Letters of
Credit, the "Letters of Credit") for the account of the Borrower on any Business
Day during the Revolving Commitment Period in such form as may be approved from
time to time by such Issuing Lender; provided, that an Issuing Lender shall have
no obligation to issue any Letter of Credit if, after giving effect to such
issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the
aggregate amount of the Available Revolving Commitments would be less than zero.
Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no
later than the earlier of (x) the first anniversary of its date of issuance and
(y) the date which is five Business Days prior to the Revolving Termination Date
(unless, in the case of this clause (y), the Borrower fully cash collateralizes
such Letter of Credit in a manner satisfactory to such Issuing Lender and the
Administrative Agent, in which case the expiration date of such Letter of Credit
shall be no later than 364 days after the Revolving Termination Date); provided,
that any Letter of Credit with a one-year term may provide for the renewal
thereof for additional one-year periods (which shall in no event extend beyond
the applicable date referred to in clause (y) above).

         (b) Each Letter of Credit shall be subject to the Uniform Customs and,
to the extent not inconsistent therewith, the laws of the State of New York.

         (c) An Issuing Lender shall not at any time be obligated to issue any
Letter of Credit hereunder if such issuance would violate or cause violation by
such Issuing Lender or any L/C Participant of any limits imposed by any
applicable Requirement of Law (exclusive of any organizational or governance
document of any Lender or Agent) imposed after the Closing Date.

         3.2 Procedure for Issuance of Letter of Credit. The Borrower may from
time to time request that an Issuing Lender issue a Letter of Credit by
delivering to such Issuing Lender at its address for notices specified herein an
Application therefor, completed to the satisfaction of such Issuing Lender, and
such other certificates, documents and other papers and information as such
Issuing Lender may request. Upon receipt of any Application, an Issuing Lender
will process such Application and the certificates, documents and other papers
and information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall an Issuing Lender be

                                       30
<PAGE>   36

required to issue any Letter of Credit earlier than one Business Day after its
receipt of the Application therefor and all such other certificates, documents
and other papers and information relating thereto) by issuing the original of
such Letter of Credit to the beneficiary thereof or as otherwise may be agreed
to by such Issuing Lender and the Borrower. Each Issuing Lender shall furnish a
copy of such Letter of Credit to the Borrower promptly following the issuance
thereof. Each Issuing Lender shall promptly furnish to the Administrative Agent,
which shall in turn promptly furnish to the Lenders, notice of the issuance of
each Letter of Credit issued by it (including the amount thereof).

         3.3 Fees and Other Charges. (a) The Borrower will pay (i) to the
Administrative Agent, for the account of the Lenders, a fee with respect to each
outstanding Letter of Credit at a per annum rate equal to the Applicable Margin
then in effect with respect to Eurodollar Loans minus the fronting fee referred
to in clause (ii) below and (ii) to the relevant Issuing Lender for its own
account with respect to each outstanding Letter of Credit a fronting fee
calculated at a rate per annum equal to 0.125%; all such fees in respect of each
Letter of Credit shall be calculated on the face amount thereof for the actual
number of days outstanding and the actual amounts outstanding (provided that in
no event shall the fronting fee for any Letter of Credit be less than $300), and
shall be payable quarterly in arrears on each L/C Fee Payment Date after the
issuance date of such Letters of Credit.

         (b) In addition to the foregoing fees, the Borrower shall pay or
reimburse each Issuing Lender for its own account for such normal and customary
costs and expenses as are incurred or charged by such Issuing Lender in
negotiating, effecting payment under, amending or otherwise administering any
Letter of Credit.

         3.4 L/C Participations. (a) Effective on the Closing Date (with respect
to the Existing Letters of Credit), and effective on the date of issuance
thereof (with respect to Letters of Credit issued after the Closing Date), each
Issuing Lender irrevocably agrees to grant and hereby grants to each L/C
Participant, and, to induce such Issuing Lenders to issue Letters of Credit
hereunder, each L/C Participant irrevocably agrees to accept and purchase and
hereby accepts and purchases from each Issuing Lender, on the terms and
conditions hereinafter stated, for such L/C Participant's own account and risk
an undivided interest equal to such L/C Participant's Revolving Percentage in
such Issuing Lender's obligations and rights under each Letter of Credit issued
hereunder and the amount of each draft paid by such Issuing Lender thereunder in
accordance with the terms of this Agreement. Notwithstanding the provisions
contained in the next to last sentence of subsection 3.5, each L/C Participant
unconditionally and irrevocably agrees with each Issuing Lender that, if a draft
is paid under any Letter of Credit issued by such Issuing Lender for which such
Issuing Lender is not reimbursed in full by the Borrower for all Reimbursement
Obligations in accordance with the terms of this Agreement, such L/C Participant
shall pay to such Issuing Lender upon demand at such Issuing Lender's address
for notices specified herein an amount equal to such L/C Participant's Revolving
Percentage of the amount of such draft, or any part thereof, which is not so
reimbursed.

         (b) If any amount required to be paid by any L/C Participant to an
Issuing Lender pursuant to subsection 3.4(a) in respect of any unreimbursed
portion of any payment

                                       31
<PAGE>   37

made by such Issuing Lender under any Letter of Credit is paid to such Issuing
Lender within three Business Days after the date such payment is due, such L/C
Participant shall pay to such Issuing Lender on demand an amount equal to the
product of (i) such amount, times (ii) the daily average Federal Funds Effective
Rate during the period from and including the date such payment is required to
the date on which such payment is immediately available to such Issuing Lender,
times (iii) a fraction the numerator of which is the number of days that elapse
during such period and the denominator of which is 360. If any such amount
required to be paid by any L/C Participant pursuant to subsection 3.4(a) is not
made available to the relevant Issuing Lender by such L/C Participant within
three Business Days after the date such payment is due, such Issuing Lender
shall be entitled to recover from such L/C Participant, on demand, such amount
with interest thereon calculated from such due date at the rate per annum
applicable to Base Rate Loans under the Revolving Facility. A certificate of an
Issuing Lender submitted to any L/C Participant with respect to any amounts
owing under this subsection 3.4(b) shall be conclusive in the absence of
manifest error.

         (c) Whenever, at any time after an Issuing Lender has made payment
under any Letter of Credit and has received from any L/C Participant its pro
rata share of such payment in accordance with subsection 3.4(a), such Issuing
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by such Issuing Lender), or any payment of interest on account thereof, such
Issuing Lender will distribute to such L/C Participant its pro rata share
thereof; provided, however, that in the event that any such payment received by
such Issuing Lender shall be required to be returned by such Issuing Lender,
such L/C Participant shall immediately return to such Issuing Lender the portion
thereof previously distributed by such Issuing Lender to it.

         3.5 Reimbursement Obligation of the Borrower. The Borrower agrees to
reimburse the relevant Issuing Lender on each date on which such Issuing Lender
notifies the Borrower of the date and amount of a draft presented under any
unexpired Letter of Credit and paid by such Issuing Lender for the amount of (a)
such draft so paid and (b) any costs or expenses provided for in subsection
3.3(b) which are incurred by such Issuing Lender in connection with such
payment. Each such payment shall be made to the relevant Issuing Lender at its
address for notices specified herein in lawful money of the United States of
America and in immediately available funds. Interest shall be payable on any and
all amounts remaining unpaid by the Borrower under this subsection 3.5 from the
date such amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the rate set forth in (i) until the second
Business Day following the date of the applicable drawing, subsection 2.10(b)
and (ii) thereafter, subsection 2.10(c). Each drawing under any Letter of Credit
shall (unless an event of the type described in clause (i) or (ii) of subsection
8(f) shall have occurred and be continuing with respect to the Borrower, in
which case the procedures specified in subsection 3.4 for funding by L/C
Participants shall apply) constitute a request by the Borrower to the
Administrative Agent for a borrowing pursuant to subsection 2.2 of Base Rate
Loans in the amount of such drawing plus interest and expenses incurred by the
relevant Issuing Lender. The Borrowing Date with respect to such borrowing shall
be the date of such drawing and all proceeds of such borrowing shall be paid to
the relevant Issuing Lender.

                                       32
<PAGE>   38

        3.6 Obligations Absolute. The Borrower's obligations under this Section
3 shall be absolute and unconditional under any and all circumstances and
irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against any Issuing Lender, any beneficiary of a
Letter of Credit or any other Person; provided, that in honoring each Letter of
Credit, such Issuing Lender has acted in good faith and has examined such Letter
of Credit and the accompanying document or documents, as the case may be, with
such care as to ascertain that on their face they appear to comply with the
terms of such Letter of Credit. The Borrower also agrees with each Issuing
Lender, subject to the proviso contained in the preceding sentence, that such
Issuing Lender shall not be responsible for, and the Borrower's Reimbursement
Obligations under subsection 3.5 shall not be affected by, among other things,
the validity or genuineness of documents or of any endorsements thereon, even
though such documents shall in fact prove to be invalid, fraudulent or forged,
or any dispute between or among the Borrower and any beneficiary of any Letter
of Credit or any other party to which such Letter of Credit may be transferred
or any claims whatsoever of the Borrower against any beneficiary of such Letter
of Credit or any such transferee. No Issuing Lender shall be liable for (i) any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such Issuing Lender, (ii) the validity or
sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason, (iii) failure of the beneficiary of any
such Letter of Credit to comply fully with conditions required in order to draw
upon such Letter of Credit, which failure is not the result of gross negligence
or willful misconduct of such Issuing Lender as determined by a final and
nonappealable decision of a court of competent jurisdiction, (iv) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing thereunder and (v) any consequences arising from causes beyond
the control of such Issuing Lender, including, without limitation, the actions
of any Governmental Authority. The Borrower agrees that any action taken or
omitted by such Issuing Lender under or in connection with any Letter of Credit
or the related drafts or documents, if done in the absence of gross negligence
or willful misconduct and in accordance with the standards or care specified in
the Uniform Commercial Code of the State of New York, shall be binding on the
Borrower and shall not result in any liability of such Issuing Lender to the
Borrower.

         3.7 Letter of Credit Payments. If any draft shall be presented for
payment under any Letter of Credit, the relevant Issuing Lender shall promptly
notify the Borrower of the date and amount thereof. The responsibility of an
Issuing Lender to the Borrower in connection with any draft presented for
payment under any Letter of Credit issued by such Issuing Lender shall, in
addition to any payment obligation expressly provided for in such Letter of
Credit, be limited to determining that the documents (including each draft)
delivered under such Letter of Credit in connection with such presentment are
substantially in conformity with such Letter of Credit and appear on their face
to comply with such Letter of Credit.

                                       33
<PAGE>   39

         3.8 Applications. To the extent that any provision of any Application
related to any Letter of Credit is inconsistent with the provisions of this
Section 3, the provisions of this Section 3 shall apply.

         3.9 Indemnification of Issuing Lender. To the extent the relevant
Issuing Lender is not reimbursed and indemnified by the Borrower, each Lender
will reimburse and indemnify such Issuing Lender in proportion to its Revolving
Percentage, for and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including
counsel fees and disbursements) or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against such Issuing
Lender in performing its duties hereunder, in any way relating to or arising out
of this Agreement and by reason of the ordinary negligence of such Issuing
Lender; provided that no Lender shall be liable to such Issuing Lender for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Issuing
Lender's gross negligence or willful misconduct. The provisions of this
subsection 3.9 shall survive any termination of this Agreement and the payment
of the Obligations and shall continue thereafter in full force and effect.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

         To induce the Agents and the Lenders to enter into this Agreement and
to make the Loans and issue or participate in the Letters of Credit, the
Borrower hereby represents and warrants to each Agent and each Lender that:

         4.1 Financial Condition. The audited consolidated balance sheet of the
Borrower and its consolidated Subsidiaries as at December 31, 1999, and the
related consolidated statements of income and of cash flows for the fiscal year
ended on such date, reported on by and accompanied by an unqualified report from
Deloitte & Touche LLP, present fairly the consolidated financial condition of
the Borrower and its consolidated Subsidiaries as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
fiscal year then ended. The unaudited consolidated balance sheet of the Borrower
and its consolidated Subsidiaries as at June 30, 2000, and the related unaudited
consolidated statements of income and cash flows for the six-month period ended
on such date, present fairly the consolidated financial condition of the
Borrower and its consolidated Subsidiaries as at such date, and the consolidated
results of its operations and its consolidated cash flows for the six -month
period then ended (subject to normal year-end audit adjustments). All such
financial statements, including the related schedules and notes thereto, have
been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein). The Borrower and its Subsidiaries do not have any
material Guarantee Obligations, contingent liabilities and liabilities for
taxes, or any long-term leases or unusual forward or long-term commitments,
including, without limitation, any interest rate or foreign currency swap or
exchange transaction or other obligation in respect of derivatives, that are not
reflected in the most recent financial statements referred to in this paragraph.
During the period from December 31, 1999 to and including the date hereof there
has

                                       34
<PAGE>   40

been no Disposition by the Borrower and its consolidated Subsidiaries of any
material part of its business or Property.

         4.2 No Change. Since December 31, 1999 there has been no development or
event which has had or could reasonably be expected to have a Material Adverse
Effect.

         4.3 Corporate Existence; Compliance with Law. Each of the Borrower and
its Subsidiaries (a) is duly organized, validly existing and in good standing
under the laws of the jurisdiction of its organization, (b) has the corporate
power and authority, and the legal right, to own and operate its Property, to
lease the Property it operates as lessee and to conduct the business in which it
is currently engaged, (c) is duly qualified as a foreign corporation and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of Property or the conduct of its business requires such
qualification, except where the failure to be so qualified and in good standing
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect and (d) is in compliance with all Requirements of Law except to the
extent that the failure to comply therewith could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect.

         4.4 Corporate Power; Authorization; Enforceable Obligations. Each Loan
Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of the Borrower, to borrow hereunder. Each Loan Party has taken all necessary
corporate action to authorize the execution, delivery and performance of the
Loan Documents to which it is a party and, in the case of the Borrower, to
authorize the borrowings on the terms and conditions of this Agreement. No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement or any of the Loan
Documents, except (i) consents, authorizations, filings and notices described in
Schedule 4.4, which consents, authorizations, filings and notices have been
obtained or made and are in full force and effect (except as noted in Schedule
4.4), and (ii) any consent that may be required to be obtained by or on behalf
of any Lender. Each Loan Document has been duly executed and delivered on behalf
of each Loan Party party thereto. This Agreement constitutes, and each other
Loan Document upon execution will constitute, a legal, valid and binding
obligation of each Loan Party party thereto, enforceable against each such Loan
Party in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

         4.5 No Legal Bar. The execution, delivery and performance of this
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any
Requirement of Law applicable to, or any material Contractual Obligation of, the
Borrower or any of its Subsidiaries and will not result in, or require, the
creation or imposition of any Lien on any of their respective properties or
revenues pursuant to any Requirement of Law or any such Contractual Obligation.
No

                                       35
<PAGE>   41

Requirement of Law or Contractual Obligation applicable to the Borrower or any
of its Subsidiaries could reasonably be expected to have a Material Adverse
Effect.

         4.6 No Material Litigation. No litigation, investigation or proceeding
of or before any arbitrator or Governmental Authority is pending or, to the
knowledge of the Borrower, threatened by or against the Borrower or any of its
Subsidiaries or against any of their respective properties or revenues (a) with
respect to any of the Loan Documents or any of the transactions contemplated
hereby or thereby or (b) which could reasonably be expected to have a Material
Adverse Effect.

         4.7 No Default. Neither the Borrower nor any of its Subsidiaries is in
default of its Contractual Obligations in any respect which could reasonably be
expected to have a Material Adverse Effect. No Default or Event of Default has
occurred and is continuing.

         4.8 Ownership of Property; Liens. Each of the Borrower and its
Subsidiaries has indefeasible title to, or a valid leasehold interest in, all of
its material real property, and good title to, or a valid leasehold interest in,
all its other material Property, and none of such Property is subject to any
Lien except as permitted by subsection 7.3.

         4.9 Intellectual Property. The Borrower and each of its Subsidiaries
owns, or is licensed to use, all Intellectual Property necessary for the conduct
of its business as currently conducted. No material claim has been asserted and
is pending against the Borrower or any of its Subsidiaries by any Person
challenging or questioning the use of any such Intellectual Property by the
Borrower or any of its Subsidiaries or the validity or effectiveness of any such
Intellectual Property, nor does the Borrower know of any valid basis for any
such claim. The use of such Intellectual Property by the Borrower and its
Subsidiaries does not infringe on the rights of any Person known by the Borrower
to have a legal right therein.

         4.10 Taxes. Each of the Borrower and its Subsidiaries has filed or
caused to be filed all Federal, state and other material tax returns which are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its Property and all
other taxes, fees or other charges imposed on it or any of its Property by any
Governmental Authority, and no tax Lien has been filed, and, to the knowledge of
the Borrower, no claim which could reasonably be expected to have a Material
Adverse Effect is being asserted, with respect to any such tax, fee or other
charge (other than any such claim the amount or validity of which is currently
being contested in good faith by appropriate proceedings and with respect to
which reserves in conformity with GAAP have been provided on the books of the
Borrower or its Subsidiaries, as the case may be).

         4.11 Federal Regulations. No part of the proceeds of any Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U as now and from time to
time hereafter in effect or for any purpose which violates the provisions of the
Regulations of the Board. 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
G-3 or FR Form U-1 referred to in Regulation U.

                                       36
<PAGE>   42

         4.12 Labor Matters. There are no strikes or other labor disputes
against the Borrower or any of its Subsidiaries pending or, to the knowledge of
the Borrower, threatened that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. Hours worked by and
payment made to employees of the Borrower and its Subsidiaries have not been in
violation of the Fair Labor Standards Act or any other applicable Requirement of
Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect if not paid have been paid or accrued
as a liability on the books of the Borrower or the relevant Subsidiary.

         4.13 ERISA. Except as set forth on Schedule 4.13, neither a Reportable
Event nor an "accumulated funding deficiency" (within the meaning of Section 412
of the Code or Section 302 of ERISA) has occurred during the five-year period
prior to the date on which this representation is made or deemed made with
respect to any Plan, and each Plan has complied in all material respects with
the applicable provisions of ERISA and the Code. No termination of a Single
Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has
arisen, during such five-year period. The present value of all accrued benefits
under each Single Employer Plan (based on those assumptions used to fund such
Plans) did not, as of the last annual valuation date prior to the date on which
this representation is made or deemed made, exceed the value of the assets of
such Plan allocable to such accrued benefits by a material amount. Neither the
Borrower nor any Commonly Controlled Entity has had a complete or partial
withdrawal from any Multiemployer Plan which has resulted or could reasonably be
expected to result in a material liability under ERISA, and neither the Borrower
nor any Commonly Controlled Entity would become subject to any material
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

         4.14 Investment Company Act; Other Regulations. No Loan Party is an
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. No Loan
Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

         4.15 Subsidiaries. The Subsidiaries listed on Schedule 4.15 constitute
all the Subsidiaries of the Borrower at the date hereof.

         4.16 Use of Proceeds. The proceeds of the Loans shall be used to
refinance certain existing Indebtedness of the Borrower and its Subsidiaries, to
provide for ongoing working capital, capital expenditures and general corporate
needs and the issuance of letters of credit.

         4.17 Environmental Matters.

                                       37
<PAGE>   43

         (a) Other than exceptions to any of the following that could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, the Borrower and each of its Subsidiaries: (i) is, and within
the period of all applicable statutes of limitation has been, in compliance with
all applicable Environmental Laws; (ii) holds all Environmental Permits (each of
which is in full force and effect) required for any of its current operations or
for any property owned, leased, or otherwise operated by it; (iii) is, and
within the period of all applicable statutes of limitation has been, in
compliance with all of its Environmental Permits; and (iv) reasonably believes
that: each of its Environmental Permits will be timely renewed and complied
with, without material expense; any additional Environmental Permits that may be
required of any of it will be timely obtained and complied with, without
material expense; and compliance with any Environmental Law that is or is
expected to become applicable to it will be timely attained and maintained.

         (b) The presence of Materials of Environmental Concern at, on, under,
in, or about any real property now owned, leased or operated by the Borrower or
any of its Subsidiaries, or at any location to which Materials of Environmental
Concern have been sent by or on behalf of the Borrower for re-use or recycling
or for treatment, storage, or disposal, could not reasonably be expected to have
a Material Adverse Effect. The Borrower has not received any notice from any
Governmental Authority or any Person having a property interest in the relevant
property that would give the Borrower reason to believe that the presence of

         (i) The guarantee contained in Section 2 of the Guarantee Agreement

then, and in any such event, (A) if such event is an Event of Default specified

obligations of the Borrower hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to the Borrower (or such other Person as may be lawfully entitled thereto).

                      SECTION 9. THE ADMINISTRATIVE AGENT

         9.1 Appointment; Nature of Relationship. Bank One, NA is hereby
appointed by each of the Lenders as its contractual representative (herein
referred to as the "Administrative Agent") hereunder and under each other Loan
Document, and each of the Lenders irrevocably authorizes the Administrative
Agent to act as the contractual representative of such Lender with

                                       53
<PAGE>   59

the rights and duties expressly set forth herein and in the other Loan
Documents. The Administrative Agent agrees to act as such contractual
representative upon the express conditions contained in this Section 9.
Notwithstanding the use of the defined term "Administrative Agent," it is
expressly understood and agreed that the Administrative Agent shall not have any
fiduciary responsibilities to any Lender by reason of this Agreement or any
other Loan Document and that the Administrative Agent is merely acting as the
contractual representative of the Lenders with only those duties as are
expressly set forth in this Agreement and the other Loan Documents. In its
capacity as the Lenders' contractual representative, the Administrative Agent
(i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a
"representative" of the Lenders within the meaning of Section 9-105 of the
Uniform Commercial Code and (iii) is acting as an independent contractor, the
rights and duties of which are limited to those expressly set forth in this
Agreement and the other Loan Documents. Each of the Lenders hereby agrees to
assert no claim against the Administrative Agent on any agency theory or any
other theory of liability for breach of fiduciary duty, all of which claims each
Lender hereby waives.

         9.2 Powers. The Administrative Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Administrative Agent.

         9.3 General Immunity. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable to the Lenders or any
Lender for any action taken or omitted to be taken by it or them hereunder or
under any other Loan Document or in connection herewith or therewith except to
the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

         9.4 No Responsibility for Loans, Recitals, etc.. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify
(a) any statement, warranty or representation made in connection with any Loan
Document or any borrowing hereunder; (b) the performance or observance of any of
the covenants or agreements of any obligor under any Loan Document, including,
without limitation, any agreement by an obligor to furnish information directly
to each Lender; (c) the satisfaction of any condition specified in Section 5,
except receipt of items required to be delivered solely to the Administrative
Agent; (d) the existence or possible existence of any Default or Event of
Default; (e) the validity, enforceability, effectiveness, sufficiency or
genuineness of any Loan Document or any other instrument or writing furnished in
connection therewith; (f) the value, sufficiency, creation, perfection or
priority of any Lien in any collateral security; or (g) the financial condition
of the Borrower or any guarantor of any of the Obligations or of any of the
Borrower's or any such guarantor's respective Subsidiaries. The

                                       54
<PAGE>   60

Administrative Agent shall have no duty to disclose to the Lenders information
that is not required to be furnished by the Borrower to the Administrative Agent
at such time, but is voluntarily furnished by the Borrower to the Administrative
Agent (either in its capacity as Administrative Agent or in its individual
capacity).

         9.5 Action on Instructions of Lenders. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders (or all Lenders, in the case of
actions which, pursuant to subsection 10.1, require the consent of all Lenders),
and such instructions and any action taken or failure to act pursuant thereto
shall be binding on all of the Lenders. The Lenders hereby acknowledge that the
Administrative Agent shall be under no duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement or any
other Loan Document unless it shall be requested in writing to do so by the
Required Lenders (or all Lenders, in the case of actions which, pursuant to
subsection 10.1, require the consent of all Lenders),. The Administrative Agent
shall be fully justified in failing or refusing to take any action hereunder and
under any other Loan Document unless it shall first be indemnified to its
satisfaction by the Lenders pro rata against any and all liability, cost and
expense that it may incur by reason of taking or continuing to take any such
action.

         9.6 Employment of Agents and Counsel. The Administrative Agent may
execute any of its duties as Administrative Agent hereunder and under any other
Loan Document by or through employees, agents, and attorneys-in-fact and shall
not be answerable to the Lenders, except as to money or securities received by
it or its authorized agents, for the default or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care. The Administrative Agent
shall be entitled to advice of counsel concerning the contractual arrangement
between the Administrative Agent and the Lenders and all matters pertaining to
the Administrative Agent's duties hereunder and under any other Loan Document.

         9.7 Reliance on Documents; Counsel. The Administrative Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal matters, upon the opinion of counsel selected by the Administrative
Agent, which counsel may be employees of the Administrative Agent.

         9.8 Administrative Agent's Reimbursement and Indemnification. The
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Revolving Commitments (or, if the Revolving
Commitments have been terminated, in proportion to their Revolving Commitments
immediately prior to such termination) (i) for any amounts not reimbursed by the
Borrower for which the Administrative Agent is entitled to reimbursement by the
Borrower under the Loan Documents, (ii) for any other expenses incurred by the
Administrative Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents (including, without limitation, for any expenses incurred by the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders) and

                                       55
<PAGE>   61

(iii) for any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of the Loan Documents
or any other document delivered in connection therewith or the transactions
contemplated thereby (including, without limitation, for any such amounts
incurred by or asserted against the Administrative Agent in connection with any
dispute between the Administrative Agent and any Lender or between two or more
of the Lenders), or the enforcement of any of the terms of the Loan Documents or
of any such other documents, provided that (i) no Lender shall be liable for any
of the foregoing to the extent any of the foregoing is found in a final
non-appealable judgment by a court of competent jurisdiction to have resulted
from the gross negligence or willful misconduct of the Administrative Agent and
(ii) any indemnification required pursuant to subsection 2.15 shall,
notwithstanding the provisions of this subsection 9.8, be paid by the relevant
Lender in accordance with the provisions thereof. The obligations of the Lenders
under this subsection 9.8 shall survive payment of the Obligations and
termination of this Agreement.

         9.9 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 written notice from a
Lender or the Borrower referring to this Agreement 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.

         9.10 Rights as a Lender. In the event the Administrative Agent is a
Lender, the Administrative Agent shall have the same rights and powers hereunder
and under any other Loan Document with respect to its Revolving Commitment and
its Loans as any Lender and may exercise the same as though it were not the
Administrative Agent, and the term "Lender" or "Lenders" shall, at any time when
the Administrative Agent is a Lender, unless the context otherwise indicates,
include the Administrative Agent in its individual capacity. The Administrative
Agent and its Affiliates may accept deposits from, lend money to, and generally
engage in any kind of trust, debt, equity or other transaction, in addition to
those contemplated by this Agreement or any other Loan Document, with the
Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is
not restricted hereby from engaging with any other Person.

         9.11 Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on the financial statements prepared by the
Borrower and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and the
other Loan Documents. Each Lender also acknowledges that it will, independently
and without reliance upon the Administrative Agent, the Arranger or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement and the other Loan Documents.

Borrower, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five days after the retiring Administrative Agent gives notice
of its intention to resign. The Administrative Agent may be removed at any time
with or without cause by written notice received by the Administrative Agent
from the Required Lenders, such removal to be effective on the date specified by
the Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within thirty days after the resigning
Administrative Agent's giving notice of its intention to resign, then the
resigning Administrative Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Administrative Agent. Notwithstanding the previous
sentence, the Administrative Agent may at any time without the consent of the
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank
as a successor Administrative Agent hereunder. If the Administrative Agent has
resigned or been removed and no successor Administrative Agent has been
appointed, the Lenders may perform all the duties of the Administrative Agent
hereunder and the Borrower shall make all payments in respect of the Obligations
to the applicable Lender and for all other purposes shall deal directly with the
Lenders. No successor Administrative Agent shall be deemed to be appointed
hereunder until such successor Administrative Agent has accepted the
appointment. Any such successor Administrative Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent. Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent shall be discharged from its duties and obligations
hereunder and under the Loan Documents and the resigning or removed
Administrative Agent shall pay to the successor Administrative Agent any
unamortized portion of Administrative Agent's fees previously paid to such
resigning or removed Administrative Agent . After the effectiveness of the
resignation or removal of an Administrative Agent, the provisions of this
Section 9 shall continue in effect for the benefit of such Administrative Agent
in respect of any actions taken or omitted to be taken by it while it was acting
as the Administrative Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Administrative Agent by merger, or the
Administrative Agent assigns its duties and obligations to an Affiliate pursuant
to this subsection 9.12, then the term "Prime Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new
Administrative Agent. Any successor Administrative Agent appointed pursuant to
this subsection 9.12 shall (unless an Event of Default under subsection 8(a) or
subsection 8(f) shall have occurred and be continuing) be subject to the
approval of the Borrower (which approval shall not be unreasonably withheld or
delayed).

         9.13 Delegation to Affiliates. The Borrower and the Lenders agree that
the Administrative Agent may delegate any of its duties under this Agreement to
any of its Affiliates. Any such Affiliate (and such Affiliate's directors,
officers, agents and employees) which performs duties in connection with this
Agreement shall be entitled to the same benefits of

                                       57
<PAGE>   63

the indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Sections 9 and 10.

         9.14 Documentation Agent, Syndication Agent, etc. Neither any of the
Lenders identified in this Agreement as a "Documentation Agent" or "Syndication
Agent" shall have any right, power, obligation, liability, responsibility or
duty under this Agreement other than those applicable to all Lenders as such.
Without limiting the foregoing, none of such Lenders shall have or be deemed to
have a fiduciary relationship with any Lender. Each Lender hereby makes the same
acknowledgments with respect to such Lenders as it makes with respect to the
Administrative Agent in subsection 9.11.

                           SECTION 10. MISCELLANEOUS

         10.1 Amendments and Waivers. Neither this Agreement, any other Loan
Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this subsection 10.1. The
Required Lenders and each Loan Party party to the relevant Loan Document may, or
(with the written consent of the Required Lenders) the Agents and each Loan
Party party to the relevant Loan Document may, from time to time, (a) enter into
written amendments, supplements or modifications hereto and to the other Loan
Documents for the purpose of adding any provisions to this Agreement or the
other Loan Documents or changing in any manner the rights of the Lenders or of
the Loan Parties hereunder or thereunder or (b) waive, on such terms and
conditions as the Required Lenders, or the Agents, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or the
other Loan Documents or any Default or Event of Default and its consequences;
provided, however, that no such waiver and no such amendment, supplement or
modification shall (i) forgive the principal amount or extend the final
scheduled date of maturity of any Loan or Reimbursement Obligation, reduce the
stated rate of any interest or fee payable hereunder or extend the scheduled
date of any payment thereof, or increase the amount or extend the expiration
date of the Revolving Commitment of any Lender, in each case without the consent
of each Lender directly affected thereby; (ii) amend, modify or waive any
provision of this subsection 10.1 or reduce any percentage specified in the
definition of Majority Lenders or Required Lenders, consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement and the other Loan Documents, or release any Material Subsidiary
Guarantor from its obligations under the Guarantee Agreement, in each case
without the consent of all Lenders; (iii) amend, modify or waive any provision
of Section 9 without the consent of the Agents; or (iv) amend, modify or waive
any provision of Section 3 without the consent of such Issuing Lender. Any such
waiver and any such amendment, supplement or modification shall apply equally to
each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the
Administrative Agent and all future holders of the Loans. In the case of any
waiver, the Loan Parties, the Lenders and the Administrative Agent shall be
restored to their former position and rights hereunder and under the other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon. Any
such waiver, amendment, supplement or modification shall be effected by a
written instrument signed by the parties required to sign pursuant to the
foregoing

                                       58

provisions of this subsection 10.1; provided, that delivery of an executed
signature page of any such instrument by facsimile transmission shall be
effective as delivery of a manually executed counterpart thereof.

         10.2 Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by

Agent, as follows, and (b) in the case of each Lender, the address of which the

party, to such other address as such party may hereafter notify to the other

provided that any notice, request or demand to or upon the Administrative Agent
or any Lender shall not be effective until received.

         10.3 No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of any party hereto, any right, remedy, power
or privilege hereunder or

                                       59
<PAGE>   65
under the other Loan Documents shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges
herein provided are cumulative and not exclusive of any rights, remedies, powers
and privileges provided by law.

         10.4 Survival of Representations and Warranties. All representations
and warranties made hereunder, in the other Loan Documents and in any document,
certificate or statement delivered pursuant hereto or in connection herewith
shall survive the execution and delivery of this Agreement and the making of the
Loans and other extensions of credit hereunder.

         10.5 Payment of Expenses. The Borrower agrees (a) to pay or reimburse
the Agents for all their reasonable out of pocket costs and expenses incurred in
connection with the development, preparation and execution of, and any
amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby
and thereby, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent and such Issuing Lender,
(b) to pay or reimburse each of the Lenders and Agents for all its reasonable
costs and expenses incurred in connection with the enforcement or preservation
of any rights under this Agreement, the other Loan Documents and any such other
documents, including, without limitation, the fees and disbursements of counsel
(including the allocated fees and expenses of in-house counsel) to each Lender
and of counsel to the Agents, (c) to pay, indemnify, and hold each Lender and
the Agents harmless from, any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay caused by any Loan
Party in paying, stamp, excise and other taxes, if any, which may be payable or
determined to be payable in connection with the execution and delivery of, or
consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, this Agreement, the other Loan Documents and any such other
documents, and (d) to pay, indemnify, and hold each Lender and the Agents and
their respective officers, directors, employees, affiliates, agents and
controlling persons (each, an "Indemnitee") harmless from and against any and
all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever with respect to the execution, delivery, enforcement, performance and
administration of this Agreement, the other Loan Documents and any such other
documents, including, without limitation, any of the foregoing relating to the
use of proceeds of the Loans or the violation of, noncompliance with or
liability under, any Environmental Law applicable to the operations of the
Borrower, any of its Subsidiaries or any property at any time owned, leased or
in any way used by the Borrower or any of its Subsidiaries (all the foregoing in
this clause (d), collectively, the "Indemnified Liabilities"), provided, that
the Borrower shall have no obligation hereunder to any Indemnitee with respect
to Indemnified Liabilities (i) to the extent such Indemnified Liabilities are
found by a final and nonappealable decision of a court of competent jurisdiction
to have resulted from the gross negligence or willful misconduct of such
Indemnitee or (ii) solely related to the transfer, assignment or other
disposition by or on behalf of any Indemnitee of any Note or any interest in its
Commitments or rights to payment under this Agreement. Without limiting the
foregoing,

                                       60
<PAGE>   66

and to the extent permitted by applicable law, the Borrower agrees not to assert
and to cause its Subsidiaries not to assert, and hereby waives and agrees to
cause its Subsidiaries so to waive, all rights for contribution or any other
rights of recovery with respect to all claims, demands, penalties, fines,
liabilities, settlements, damages, costs and expenses of whatever kind or
nature, under or related to Environmental Laws, that any of them now or
hereafter might have by statute or otherwise against any indemnitee. The
agreements in this subsection 10.5 shall survive repayment of the Loans and all
other amounts payable hereunder.

         10.6 Successors and Assigns; Participations and Assignments. (a) This
Agreement shall be binding upon and inure to the benefit of the Borrower, the
Lenders, the Agents, all future holders of the Loans and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agents and each Lender.

         (b) Any Lender may, without the consent of the Borrower, in accordance
with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant") participating interests
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the other Loan Documents, and the
Borrower and the Agents shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and the other Loan Documents. In no event shall any Participant under
any such participation have any right to approve any amendment or waiver of any
provision of any Loan Document, or any consent to any departure by any Loan
Party therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Loans or any fees payable
hereunder, or postpone the date of the final maturity of the Loans, in each case
to the extent subject to such participation. The Borrower agrees that if amounts
outstanding under this Agreement and the Loans are due but unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall, to the maximum extent permitted by
applicable law, be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement, provided that, in purchasing such participating
interest, such Participant shall be deemed to have agreed to share with the
Lenders the proceeds thereof as provided in subsection 10.7(a) as fully as if it
were a Lender hereunder. The Borrower also agrees that each Participant shall be
entitled to the benefits of subsections 2.14, 2.15 and 2.16 with respect to its
participation in the Revolving Commitments and the Loans outstanding from time
to time as if it was a Lender; provided that, in the case of subsection 2.15,
such Participant shall have complied with the requirements of such subsection
and provided, further, that no Participant shall be entitled to receive any
greater amount pursuant to any such subsection than the transferor Lender would
have been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such Participant had no such transfer
occurred.

                                       61
<PAGE>   67

         (c) Any Lender (an "Assignor") may, in accordance with applicable law,
at any time and from time to time assign to (i) any Lender or any affiliate
thereof (provided that the consent of such Issuing Lender shall be obtained in
connection with any assignment of Revolving Commitments to an affiliate of a
Lender), (ii) with the consent of the Borrower, the Administrative Agent and
such Issuing Lender, (which, in each case, shall not be unreasonably withheld or
delayed), to an additional bank, financial institution or other entity (an
"Assignee") all or any part of its rights and obligations under this Agreement
pursuant to an Assignment and Acceptance, substantially in the form of Exhibit
D, executed by such Assignee and such Assignor (and, where the consent of the
Borrower, the Administrative Agent or such Issuing Lender is required pursuant
to the foregoing provisions, by the Borrower or the Borrower and such other
Persons, as the case may be) and delivered to the Administrative Agent for its
acceptance and recording in the Register; provided that, unless otherwise agreed
by the Borrower and the Administrative Agent, and except in the case of an
assignment by a Lender of all of its Revolving Commitment and/or Loans under
this Agreement and the 364-Day Revolving Credit Agreement, (i) no assignment to
an Assignee (other than any Lender or any affiliate thereof) of Revolving
Commitment and/ or Loans under this Agreement shall be in an amount which, when
aggregated with the amount of Revolving Commitment and/ or Loans under (and as
defined in) the 364-Day Revolving Credit Agreement assigned concurrently with
such assignment hereunder, is less than $5,000,000 and (ii) after giving effect
to any assignment hereunder, the Assignor must have Revolving Commitment and/or
Loans under this Agreement in an amount which, when aggregated with the amount
of Revolving Commitment and/ or Loans of such Assignor under (and as defined in)
the 364-Day Revolving Credit Agreement, is at least $10,000,000. Each assignment
of Revolving Commitments and/or Loans by a Lender must be accompanied by an
assignment by such Assignor Lender to the same Assignee of a proportionate
amount of such Assignor Lender's Revolving Commitments and/or Loans under (and
as defined in) the 364-Day Revolving Credit Agreement. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with a Revolving
Commitment and/or Loans as set forth therein, and (y) the Assignor thereunder
shall, to the extent provided in such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of an Assignor's rights and obligations under this
Agreement, such Assignor shall cease to be a party hereto). Notwithstanding any
provision of this subsection 10.6(c), the consent of the Borrower shall not be
required for any assignment which occurs at any time when any Event of Default
shall have occurred and be continuing.

         (d) The Administrative Agent shall, on behalf of the Borrower, maintain
at its address referred to in subsection 10.2 a copy of each Assignment and
Acceptance delivered to it and a register (the "Register") for the recordation
of the names and addresses of the Lenders and the Revolving Commitment of, and
principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, the Administrative Agent and the Lenders shall treat each
Person whose name is recorded in the Register as the owner of the Loans and any
Notes evidencing such Loans recorded therein for all purposes of this Agreement.
Any assignment of any Loan, whether or

                                       62
<PAGE>   68

not evidenced by a Note, shall be effective only upon appropriate entries with
respect thereto being made in the Register (and each Note shall expressly so
provide). Any assignment or transfer of all or part of a Loan evidenced by a
Note shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note evidencing such Loan, accompanied by a duly
executed Assignment and Acceptance; thereupon one or more new Notes in the same
aggregate principal amount shall be issued to the designated Assignee, and the
old Notes shall be returned by the Administrative Agent to the Borrower marked
"cancelled". 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.

         (e) Upon its receipt of an Assignment and Acceptance executed by an
Assignor and an Assignee (and, in any case where the consent of any other Person
is required by subsection 10.6(c), by each such other Person) together with
payment by such Assignor and/or such Assignee (as agreed between them) to the
Administrative Agent of a registration and processing fee of $3,500 (except that
no such registration and processing fee shall be payable in the case of an
Assignee which is already a Lender or is an affiliate of a Lender or a Person
under common management with a Lender), the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give notice of such acceptance and recordation to the Lenders and
the Borrower. On or prior to such effective date, the Borrower, at its own
expense, upon request, shall execute and deliver to the Administrative Agent (in
exchange for the Note of the assigning Lender) a new Note, to the order of such
Assignee in an amount equal to the Revolving Commitment assumed or acquired by
it pursuant to such Assignment and Acceptance and, if the Assignor has retained
a Revolving Commitment, upon request, a new Note, to the order of the Assignor
in an amount equal to the Revolving Commitment, retained by it hereunder. Such
new Note or Notes shall be dated the Closing Date and shall otherwise be in the
form of the Note or Notes replaced thereby.

         (f) For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this subsection 10.6 concerning assignments of Loans and
Notes relate only to absolute assignments and that such provisions do not
prohibit assignments creating security interests, including, without limitation,
any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve
Bank in accordance with applicable law; provided, that all related costs, fees
and expenses assessed against or incurred by such Lender solely in connection
with any such assignment to any Federal Reserve Bank or any related
re-assignment to such Lender shall be for the sole account of such Lender.

         10.7 Adjustments; Set-off. (a) If any Lender (a "Benefitted Lender")
shall at any time receive any payment of all or part of the Obligations owing to
it, or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in subsection 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's Obligations, such Benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Obligations, or shall provide such other Lenders with the
benefits of any such collateral, as shall be necessary to cause

                                       63
<PAGE>   69

such Benefitted Lender to share the excess payment or benefits of such
collateral ratably with each of the Lenders; provided, however, that if all or
any portion of such excess payment or benefits is thereafter recovered from such
Benefitted Lender, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest.

         (b) In addition to any rights and remedies of the Lenders provided by
law, at any time when an Event of Default is in existence, each Lender shall
have the right, without prior notice to the Borrower, any such notice being
expressly waived by the Borrower to the extent permitted by applicable law, upon
any amount becoming due and payable by the Borrower hereunder (whether at the
stated maturity, by acceleration or otherwise), to set off and appropriate and
apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency thereof to or for the credit or the
account of the Borrower, as the case may be. Each Lender agrees promptly to
notify the Borrower and the Administrative Agent after any such setoff and
application made by such Lender, provided that the failure to give such notice
shall not affect the validity of such setoff and application.

         10.8 Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

         10.9 Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         10.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Agents and the Lenders with respect
to the subject matter hereof, and there are no promises, undertakings,
representations or warranties by any Agent or any Lender relative to subject
matter hereof not expressly set forth or referred to herein or, in the other
Loan Documents.

         10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

         10.12 Submission To Jurisdiction; Waivers (a) The Borrower hereby
irrevocably and unconditionally:

                                       64
<PAGE>   70

          (i) submits for itself and its Property in any legal action or
     proceeding relating to this Agreement and the other Loan Documents to which
     it is a party, or for recognition and enforcement of any judgment in
     respect thereof, to the non-exclusive general jurisdiction of the courts of
     the State of New York, the courts of the United States of America for the
     Southern District of New York, and appellate courts from any thereof;

          (ii) consents that any such action or proceeding may be brought in
     such courts and waives any objection that it may now or hereafter have to
     the venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (iii) agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     Borrower at its address set forth in subsection 10.2 or at such other
     address of which the Administrative Agent shall have been notified pursuant
     thereto; and

          (iv) agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the
     right to sue in any other jurisdiction.

         (b) Each party hereto hereby waives, to the maximum extent not
prohibited by law, any right it may have to claim or recover in any legal action
or proceeding referred to in this subsection 10.12 any special, exemplary,
punitive or consequential damages.

         10.13 Acknowledgements. The Borrower hereby acknowledges that:

         (a) it has been advised by counsel in the negotiation, execution and
delivery of this Agreement and the other Loan Documents;

         (b) neither the Administrative Agent nor any Lender has any fiduciary
relationship with or duty to the Borrower arising out of or in connection with
this Agreement or any of the other Loan Documents, and the relationship between
Administrative Agent and Lenders, on one hand, and the Borrower, on the other
hand, in connection herewith or therewith is solely that of debtor and creditor;
and

         (c) no joint venture is created hereby or by the other Loan Documents
or otherwise exists by virtue of the transactions contemplated hereby among the
Lenders or among the Borrower and the Lenders.

         10.14 Confidentiality. Each of the Agents and the Lenders agrees to
keep confidential all non-public information provided to it by any Loan Party
pursuant to this Agreement that is designated by such Loan Party as
confidential; provided that nothing herein shall prevent any Agent or any Lender
from disclosing any such information (a) to the Administrative Agent, any other
Lender or any affiliate of any Lender, (b) to any Participant or Assignee (each,
a "Transferee") or prospective Transferee which agrees to comply with the

                                       65
<PAGE>   71

provisions of this subsection 10.14, (c) any of its employees, directors,
agents, attorneys, accountants and other professional advisors, (d) upon the
request or demand of any Governmental Authority having jurisdiction over it, (e)
in response to any order of any court or other Governmental Authority or as may
otherwise be required pursuant to any Requirement of Law (exclusive of any
organizational or governance document of such Agent or Lender), (f) if requested
or required to do so in connection with any litigation or similar proceeding,
(g) which has been publicly disclosed other than in breach of this subsection
10.14, (h) to the National Association of Insurance Commissioners or any similar
organization or any nationally recognized rating agency that requires access to
information about a Lender's investment portfolio in connection with ratings
issued with respect to such Lender or (i) in connection with the exercise of any
remedy hereunder or under any other Loan Document. In the event that any Agent
or Lender shall have received a demand or request, or intends to respond to or
otherwise satisfy a requirement, for the delivery of any such confidential
information pursuant to the foregoing clause (f), such Agent or Lender promptly
shall make reasonable efforts to notify the Borrower thereof within any
applicable time period permitted to contest compliance with any such demand,
request or requirement; provided, that in no event shall any Lender or Agent be
liable for any action taken pursuant to such clause (f) or for any failure so to
notify the Borrower in accordance with the foregoing.

         10.15 Enforceability; Usury. In no event shall any provision of this
Agreement, the Notes, or any other instrument evidencing or securing the
indebtedness of the Borrower hereunder ever obligate the Borrower to pay or
allow any Lender to collect interest on the Loans or any other indebtedness of
the Borrower hereunder at a rate greater than the maximum non-usurious rate
permitted by applicable law (herein referred to as the "Highest Lawful Rate"),
or obligate the Borrower to pay any taxes, assessments, charges, insurance
premiums or other amounts to the extent that such payments, when added to the
interest payable on the Loans, would be held to constitute the payment by the
Borrower of interest at a rate greater than the Highest Lawful Rate; and this
provision shall control over any provision to the contrary.

         Without limiting the generality of the foregoing, in the event the
maturity of all or any part of the principal amount of the indebtedness of the
Borrower hereunder shall be accelerated for any reason, then such principal
amount so accelerated shall be credited with any interest theretofore paid
thereon in advance and remaining unearned at the time of such acceleration. If,
pursuant to the terms of this Agreement or the Notes, any funds are applied to
the payment of any part of the principal amount of the indebtedness of the
Borrower hereunder prior to the maturity thereof, then (a) any interest which
would otherwise thereafter accrue on the principal amount so paid by such
application shall be canceled, and (b) the indebtedness of the Borrower
hereunder remaining unpaid after such application shall be credited with the
amount of all interest, if any, theretofore collected on the principal amount so
paid by such application and remaining unearned at the date of said application;
and if the funds so applied shall be sufficient to pay in full all the
indebtedness of the Borrower hereunder, then the Lenders shall refund to the
Borrower all interest theretofore paid thereon in advance and remaining unearned
at the time of such acceleration. All sums paid or agreed to be paid to the
Administrative Agent or to any Lender for the use, forbearance or detention of
sums due hereunder shall, to the extent permitted by law applicable to the
Administrative Agent or such Lender, be amortized, prorated, allocated

                                       66
<PAGE>   72

and spread throughout the full term of the Loans until paid in full, so that the
rate or amount of interest on account of any Loans or other amounts hereunder
does not exceed the maximum amount allowed by such applicable law. Regardless of
any other provision in this Agreement, or in any of the written evidences of the
indebtedness of the Borrower hereunder, the Borrower shall never be required to
pay any unearned interest on such indebtedness or any portion thereof, and shall
never be required to pay interest thereon at a rate in excess of the Highest
Lawful Rate construed by courts having competent jurisdiction thereof.

         10.16 Accounting Changes. In the event that any "Accounting Change" (as
defined below) shall occur and such change results in a change in the method of
calculation of financial covenants, standards or terms in this Agreement, then
the Borrower and the Administrative Agent agree to enter into negotiations in
order to amend such provisions of this Agreement so as to equitably reflect such
Accounting Changes with the desired result that the criteria for evaluating the
Borrower's financial condition shall be the same after such Accounting Changes
as if such Accounting Changes had not been made. Until such time as such an
amendment shall have been executed and delivered by the Borrower, the
Administrative Agent and the Required Lenders, all financial covenants,
standards and terms in this Agreement shall continue to be calculated or
construed as if such Accounting Changes had not occurred. "Accounting Changes"
refers to changes in accounting principles required by the promulgation of any
rule, regulation, pronouncement or opinion by the Financial Accounting Standards
Board or the American Institute of Certified Public Accountants or, if
applicable, the Securities and Exchange Commission (or successors thereto or
agencies with similar functions).

         10.17 WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS AND THE LENDERS
HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION
OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM THEREIN.

Changes in the Applicable Margin resulting from changes in the Consolidated
Leverage Ratio shall become effective on the date (the "Adjustment Date") on
which financial statements are delivered to the Lenders pursuant to subsection
6.1 (but in any event not later than the 60th day after the end of each of the
first three quarterly periods of each fiscal year or the 105th day after the end
of each fiscal year, as the case may be) and shall remain in effect until the
next change to be effected pursuant to this paragraph. If any financial
statements referred to above are not delivered within the time periods specified
above, then, until such financial statements are delivered, the Consolidated
Leverage Ratio as at the end of the fiscal period that would have been covered
thereby shall for the purposes of this definition be deemed to be greater than
3.25 : 1.0. In addition, at all times while an Event of Default shall have
occurred and be continuing, the Consolidated Leverage Ratio shall for the
purposes of this definition be deemed to be greater than 3.25 : 1.0. Each
determination of the Consolidated Leverage Ratio pursuant to this definition
shall be made with respect to the period of four consecutive fiscal quarters of
the Borrower and its consolidated Subsidiaries ending at the end of the period
covered by the relevant consolidated financial statements; provided that the
Consolidated EBITDA used to calculate the Consolidated Leverage Ratio for the
fiscal quarter ended September 30, 2000 be will equal 1.33 times the sum of the
Consolidated EBITDA for the three consecutive fiscal quarters ended on such
date.

              SECTION 2. AMOUNT AND TERMS OF REVOLVING COMMITMENTS

                  2.1 Revolving Commitments (a) Subject to the terms and
conditions hereof, each Lender severally agrees to make revolving loans
("Loans") to the Borrower from time to time during the Revolving Commitment
Period in an aggregate principal amount at any one time outstanding which, when
added to such Lender's Revolving Percentage of the L/C Obligations then
outstanding, does not exceed the amount of such Lender's Revolving Commitment.
During

                                       18
<PAGE>   24

the Revolving Commitment Period the Borrower may use the Revolving Commitments
by borrowing, prepaying the Loans in whole or in part, and reborrowing, all in
accordance with the terms and conditions hereof. The Loans may from time to time
be Eurodollar Loans or Base Rate Loans, as determined by the Borrower and
notified to the Administrative Agent in accordance with subsections 2.2 and 2.8,
provided that no Loan shall be made as a Eurodollar Loan after the day that is
one month prior to the Revolving Termination Date.

                  (b) The Borrower shall repay all outstanding Loans on the
Revolving Termination Date.

                  2.2 Procedure for Borrowing (a) The Borrower may borrow under
the Revolving Commitments during the Revolving Commitment Period on any Business
Day, provided that the Borrower shall give the Administrative Agent irrevocable
notice (which notice must be received by the Administrative Agent prior to 11:00
a.m., Central Time, (a) in the case of Eurodollar Loans, three Business Days
prior to the requested Borrowing Date, or (b) in the case of Base Rate Loans, on
the requested Borrowing Date), specifying (i) the amount and Type of Loans to be
borrowed, (ii) the requested Borrowing Date and (iii) in the case of Eurodollar
Loans, the respective amounts of each such Type of Loan and the respective
lengths of the initial Interest Period therefore. Each borrowing under the
Revolving Commitments shall be in an amount equal to (x) in the case of Base
Rate Loans, $1,000,000 or a whole multiple of $500,000 in excess thereof (or, if
the then aggregate Available Revolving Commitments are less than $500,000, such
lesser amount) and (y) in the case of Eurodollar Loans, $1,000,000 or a whole
multiple of $1,000,000 in excess thereof. Upon receipt of any such notice from
the Borrower, the Administrative Agent shall promptly notify each Lender
thereof. Each Lender will make the amount of its pro rata share of each
borrowing available to the Administrative Agent for the account of the Borrower
at the Funding Office prior to 1:00 p.m., Central Time (in the case of a
borrowing of Base Rate Loans in respect of which notice of such borrowing is
given on such Borrowing Date) and 11:00 a.m. Central Time (in the case of any
other borrowing), on the Borrowing Date requested by the Borrower in funds
immediately available to the Administrative Agent. The Administrative Agent
shall make available to the Borrower the aggregate of the amounts made available
to the Administrative Agent by the Lenders in like funds as received by the
Administrative Agent.

                  2.3 Repayment of Loans; Evidence of Debt (a) The Borrower
hereby unconditionally promises to pay to the Administrative Agent for the
account of the appropriate Lender the then unpaid principal amount of each Loan
of such Lender on the Revolving Termination Date (or such earlier date on which
the Loans become due and payable pursuant to Section 8). The Borrower hereby
further agrees to pay interest on the unpaid principal amount of the Loans from
time to time outstanding from the date hereof until payment in full thereof at
the rates per annum, and on the dates, set forth in subsection 2.10.

                  (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such
Lender resulting from each Loan of 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.

                                       19
<PAGE>   25

                  (c) The Administrative Agent, on behalf of the Borrower, shall
maintain the Register pursuant to subsection 10.6(e), and a subaccount therein
for each Lender, in which shall be recorded (i) the amount of each Loan made
hereunder and any Note evidencing such Loan, the Type thereof and each Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder
and (iii) both the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

                  (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to subsection 2.3(b) shall, to the extent permitted
by applicable law, be prima facie evidence (in the absence of manifest error) 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 the Register or any such account, or any error therein, shall not in
any manner affect the obligation of the Borrower to repay (with applicable
interest) the Loans made to such Borrower by such Lender in accordance with the
terms of this Agreement.

                  (e) The Borrower agrees that, upon the request to the
Administrative Agent by any Lender, the Borrower will execute and deliver to
such Lender a promissory note of the Borrower evidencing any Loans of such
Lender, substantially in the form of Exhibit F, with appropriate insertions as
to date and principal amount.

                  2.4 Commitment Fees, etc (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee for the
period from and including the Closing Date to the last day of the Revolving
Commitment Period, computed at the Commitment Fee Rate on the average daily
amount of the Available Revolving Commitment of such Lender during the period
for which payment is made, payable quarterly in arrears on the first day of each
January, April, July and October and on the Revolving Termination Date,
commencing on the first of such dates to occur after the date hereof.

                  (b) The Borrower agrees to pay to the Administrative Agent the
fees in the amounts and on the dates from time to time agreed to in writing by
the Borrower and the Administrative Agent.

                  2.5 Termination or Reduction of Revolving Commitments. The
Borrower shall have the right, upon not less than three Business Days' notice to
the Administrative Agent, to terminate any of the Revolving Commitments or, from
time to time, to reduce the amount of any of the Revolving Commitments;
provided, that no such termination or reduction of Revolving Commitments shall
be permitted if, after giving effect thereto and to any prepayments of the Loans
made on the effective date thereof, the Total Revolving Extensions of Credit
would exceed the Total Revolving Commitments. Any such reduction shall be in a
minimum amount equal to $5,000,000, or a whole multiple of $1,000,000 in excess
thereof (or, if the then aggregate Revolving Commitments are less than
$5,000,000, such lesser amount), and shall reduce permanently the relevant
Revolving Commitments then in effect.

                  2.6 Optional Prepayments. The Borrower may at any time and
from time to time prepay the Loans, in whole or in part, without premium or
penalty, upon irrevocable notice

                                       20
<PAGE>   26

delivered to the Administrative Agent at least three Business Days prior thereto
in the case of Eurodollar Loans and, prior to 11:00 a.m., Central Time, on the
date of such prepayment in the case of Base Rate Loans, which notice shall
specify the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans or Base Rate Loans; provided, that if a Eurodollar Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, the Borrower shall also pay any amounts owing pursuant to subsection
2.16. Upon receipt of any such notice the Administrative Agent shall promptly
notify each relevant Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified therein,
together with (except in the case of Base Rate Loans) accrued interest to such
date on the amount prepaid. Partial prepayments of Loans shall be in an
aggregate principal amount of $1,000,000 or a whole multiple thereof (or if the
then aggregate principal amount of Loans outstanding is less than $1,000,000,
such lesser amount).

                  2.7 Mandatory Commitment Termination and Prepayment upon
Change of Control. Upon the occurrence of a Change of Control, (a)
automatically, without any notice, the Revolving Commitments shall immediately
terminate and (b) the Borrower shall immediately prepay all Loans, together with
all accrued and unpaid interest thereon and shall immediately cash collateralize
all outstanding L/C Obligations in the manner contemplated by the last paragraph
of Section 8.

                  2.8 Conversion and Continuation Options. (a) The Borrower may
elect from time to time to convert Eurodollar Loans to Base Rate Loans by giving
the Administrative Agent at least one Business Day's prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert Base Rate Loans to Eurodollar Loans by
giving the Administrative Agent at least three Business Days' prior irrevocable
notice of such election (which notice shall specify the length of the initial
Interest Period therefore), provided, that no Base Rate Loan may be converted
into a Eurodollar Loan (i) when any Event of Default has occurred and is
continuing and the Administrative Agent or the Majority Lenders have determined
in its or their sole discretion not to permit such conversions or (ii) after the
date that is one month prior to the Revolving Termination Date. Upon receipt of
any such notice, the Administrative Agent shall promptly notify each Lender
thereof.

                  (b) Any Eurodollar Loan may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving irrevocable notice to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
subsection 1.1, of the length of the next Interest Period to be applicable to
such Loans, provided, that no Eurodollar Loan may be continued as such (i) when
any Event of Default has occurred and is continuing and the Administrative Agent
has or the Majority Lenders have determined in its or their sole discretion not
to permit such continuations or (ii) after the date that is one month prior to
the Revolving Termination Date, and provided, further, that if the Borrower
shall fail to give any required notice as described above in this paragraph or
if such continuation is not permitted pursuant to the preceding proviso such
Loans shall be automatically

                                       21
<PAGE>   27

converted to Base Rate Loans on the last day of such then expiring Interest
Period. Upon receipt of any such notice, the Administrative Agent shall promptly
notify each relevant Lender thereof.

                  2.9 Minimum Amounts and Maximum Number of Eurodollar Tranches.
Notwithstanding anything to the contrary in this Agreement, all borrowings,
conversions, continuations and optional prepayments of Eurodollar Loans
hereunder and all selections of Interest Periods hereunder shall be in such
amounts and be made pursuant to such elections so that, (a) after giving effect
thereto, the aggregate principal amount of the Eurodollar Loans comprising each
Eurodollar Tranche shall be equal to $1,000,000 or a whole multiple of
$1,000,000 in excess thereof and (b) no more than six Eurodollar Tranches shall
be outstanding at any one time.

                  2.10 Interest Rates and Payment Dates. (a) Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
Interest Period plus the Applicable Margin.

                  (b) Each Base Rate Loan shall bear interest at a rate per
annum equal to the Base Rate plus the Applicable Margin.

                  (c) (i) If all or a portion of the principal amount of any
Loan or Reimbursement Obligation shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum which is equal to (x) in the case of the Loans, the
rate that would otherwise be applicable thereto pursuant to the foregoing
provisions of this subsection 2.10 plus 2% or (y) in the case of Reimbursement
Obligations, the rate applicable to Base Rate Loans plus 2%, and (ii) if all or
a portion of any interest payable on any Loan or Reimbursement Obligation or any
commitment fee or other amount payable hereunder shall not be paid when due
(whether at the stated maturity, by acceleration or otherwise), such overdue
amount shall bear interest at a rate per annum equal to the rate then applicable
to Base Rate Loans plus 2%, in each case, with respect to clauses (i) and (ii)
above, from the date of such non-payment until such amount is paid in full (as
well after as before judgment).

                  (d) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (c) of this
subsection 2.10 shall be payable from time to time on demand.

                  2.11 Computation of Interest and Fees. (a) Interest, fees and
commissions payable pursuant hereto shall be calculated on the basis of a
360-day year for the actual days elapsed, except that, with respect to Base Rate
Loans the rate of interest on which is calculated on the basis of the Prime
Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-,
as the case may be) day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the Borrower and the Lenders of each
determination of a Eurodollar Rate. Any change in the interest rate on a Loan
resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective. The Administrative Agent shall as soon as

                                       22
<PAGE>   28

practicable notify the Borrower and the Lenders of the effective date and the
amount of each such change in interest rate.

                  (b) Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to subsection
2.10(a).

                  2.12 Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                  (a) the Administrative Agent shall have determined in good
faith (which determination shall be conclusive and binding upon the Borrower)
that, by reason of circumstances affecting the relevant market, adequate and
reasonable means do not exist for ascertaining the Eurodollar Rate for such
Interest Period, or

                  (b) the Administrative Agent shall have received notice from
the Majority Lenders that the Eurodollar Rate determined or to be determined for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders (as conclusively certified by such Lenders) of making or maintaining
their affected Loans during such Interest Period,

then the Administrative Agent shall give telecopy or telephonic notice thereof
to the Borrower and the relevant Lenders as soon as practicable thereafter. If
such notice is given (x) any Eurodollar Loans requested to be made on the first
day of such Interest Period shall be made as Base Rate Loans, (y) any Loans that
were to have been converted on the first day of such Interest Period to
Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding
Eurodollar Loans shall be converted, on the last day of the Interest Period then
in effect with respect to such Eurodollar Loans, to Base Rate Loans. Until such
notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans shall be made or continued as such, nor shall the Borrower have the right
to convert Loans to Eurodollar Loans.

                  2.13 Pro Rata Treatment and Payments. (a) Each borrowing by
the Borrower from the Lenders hereunder, each payment by the Borrower on account
of any commitment fee and any reduction of the Revolving Commitments of the
Lenders shall be made pro rata according to the Revolving Percentages of the
Lenders. Each payment (including prepayments) in respect of principal or
interest in respect of the Loans, each payment in respect of fees payable
hereunder, and each payment in respect of Reimbursement Obligations, shall be
applied to the amounts of such obligations owing to the Lenders pro rata
according to the respective amounts then due and owing to the Lenders.

                  (b) All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, Central Time, on the due date thereof to the Administrative
Agent, for the account of the Lenders, at the Payment Office, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such

                                       23
<PAGE>   29

payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurodollar Loan becomes
due and payable on a day other than a Business Day, the maturity thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

                  (c) Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefore, such Lender shall
pay to the Administrative Agent, on demand, such amount with interest thereon at
a rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum equal to the
daily average Federal Funds Effective Rate, on demand, from the Borrower.

                  (d) Unless the Administrative Agent shall have been notified
in writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

                  2.14 Requirements of Law (a) If the adoption of or any change
in any Requirement of Law (exclusive of any organizational or governance
document of any Lender or Agent) or in the interpretation or application thereof
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                                       24

<PAGE>   30
                (i)      shall subject any Lender to any tax of any kind
                         whatsoever with respect to this Agreement, any Letter
                         of Credit, any Application or any Eurodollar Loan made
                         by it, or change the basis of taxation of payments to
                         such Lender in respect thereof (except for Non-Excluded
                         Taxes covered by subsection 2.15 and changes in the
                         rate of tax on the overall net income of such Lender);

                (ii)     shall impose, modify or hold applicable any reserve,
                         special deposit, compulsory loan or similar requirement
                         against assets held by, deposits or other liabilities
                         in or for the account of, advances, loans or other
                         extensions of credit by, or any other acquisition of
                         funds by, any office of such Lender which is not
                         otherwise included in the determination of the
                         Eurodollar Rate hereunder; or

                (iii)    shall impose on such Lender any other condition; and
                         the result of any of the foregoing is to increase the
                         cost to such Lender, by an amount which such Lender
                         deems to be material, of making, converting into,
                         continuing or maintaining Eurodollar Loans or issuing
                         or participating in Letters of Credit, or to reduce any
                         amount receivable hereunder in respect thereof,

then, in any such case, the Borrower shall promptly pay such Lender, upon its
demand, any additional amounts necessary to compensate such Lender for such
increased cost or reduced amount receivable. If any Lender becomes entitled to
claim any additional amounts pursuant to this subsection 2.14, it shall promptly
notify the Borrower (with a copy to the Administrative Agent) of the event by
reason of which it has become so entitled.

                  (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law (exclusive of any organizational or
governance document of any Lender or Agent) regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefore, the Borrower shall pay to such Lender
such additional amount or amounts as will compensate such Lender for such
reduction.

                  (c) A certificate as to any additional amounts payable
pursuant to this subsection 2.14 submitted by any Lender to the Borrower (with a
copy to the Administrative Agent) shall be conclusive in the absence of manifest
error. The obligations of the Borrower pursuant to this subsection 2.14 shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

<PAGE>   31

                  2.15 Taxes. (a) All payments made by the Borrower under this
Agreement 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 Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on any Agent or any Lender as a result of a present or
former connection between such Agent or such Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
such Agent or such Lender having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
other Loan Document). If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") or Other Taxes
are required to be withheld from any amounts payable to any Agent or any Lender
hereunder, the amounts so payable to such Agent or such Lender shall be
increased to the extent necessary to yield to such Agent or such Lender (after
payment of all Non-Excluded Taxes and Other Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement, provided, however, that the Borrower shall not be required to
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this subsection 2.15 or (ii) that are
United States withholding taxes imposed on amounts payable to such Lender at the
time the Lender becomes a party to this Agreement, except to the extent that
such Lender's assignor (if any) was entitled, at the time of assignment, to
receive additional amounts from the Borrower with respect to such Non-Excluded
Taxes pursuant to this subsection 2.15(a).

                  (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

                  (c) Whenever any Non-Excluded Taxes or Other Taxes are payable
by the Borrower, as promptly as possible thereafter the Borrower shall send to
the Administrative Agent for the account of the relevant Agent or Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof or other evidence of payment thereof
satisfactory to the Administrative Agent. If the Borrower fails to pay any
Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority
or fails to remit to the Agents the required receipts or other required
documentary evidence, the Borrower shall indemnify the Administrative Agent and
the Lenders for any incremental taxes, interest or penalties that may become
payable by any Agent or any Lender as a result of any such failure. The
agreements in this subsection 2.15 shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

                  (d) Each Lender (or Transferee) that is not a citizen or
resident of the United States of America, a corporation, partnership or other
entity created or organized in or under the laws of the United States of America
(or any jurisdiction thereof), or any estate or trust that is subject to federal
income taxation regardless of the source of its income (a "Non-U.S. Lender")
shall deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) two copies of either U.S.

                                       26
<PAGE>   32

Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a
Non-U.S. Lender claiming exemption from U.S. federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of "portfolio
interest" a statement substantially in the form of Exhibit G and a Form W-8BEN,
or any subsequent versions thereof or successors thereto properly completed and
duly executed by such Non-U.S. Lender claiming complete exemption from, or a
reduced rate of, U.S. federal withholding tax on all payments by the Borrower
under this Agreement and the other Loan Documents. 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 any Participant, on or before the date such
Participant purchases the related participation). 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. Each Non-U.S. Lender
shall promptly notify the Borrower at any time it determines that it is no
longer in a position to provide any previously delivered certificate to the
Borrower (or any other form of certification adopted by the U.S. taxing
authorities for such purpose). Notwithstanding any other provision of this
paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant
to this paragraph that such Non-U.S. Lender is not legally able to deliver.

                  (e) A Lender that is entitled to an exemption from or
reduction of non-U.S. withholding tax under the law of the jurisdiction in which
the Borrower is located, or any treaty to which such jurisdiction is a party,
with respect to payments under this Agreement shall deliver to the Borrower
(with a copy to the Administrative Agent), at the time or times prescribed by
applicable law or reasonably requested by the Borrower, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Lender is legally entitled to complete, execute and deliver such documentation
and in such Lender's reasonable judgment such completion, execution or
submission would not materially prejudice the legal position of such Lender.

                  2.16 Indemnity. The Borrower agrees 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 making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment of Eurodollar
Loans on a day which is not the last day of an Interest Period with respect
thereto. Such indemnification may include an amount equal to the excess, if any,
of (i) the amount of interest which would have accrued on the amount so prepaid,
or not so borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar
market. A certificate as to any

                                       27
<PAGE>   33

amounts payable pursuant to this subsection 2.16 submitted to the Borrower by
any Lender shall be conclusive in the absence of manifest error. This covenant
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

                  2.17 Illegality. Notwithstanding any other provision herein,
if the adoption of or any change in any Requirement of Law (exclusive of any
organizational or governance document of any Lender or Agent) or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be cancelled and (b) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to subsection
2.16.

                  2.18 Change of Lending Office. Each Lender agrees that, upon
the occurrence of any event giving rise to the operation of subsection 2.14,
2.15(a) or 2.17 with respect to such Lender, it will, if requested by the
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender) to designate another lending office for any Loans affected by such
event with the object of avoiding the consequences of such event; provided, that
such designation is made on terms that, in the sole judgment of such Lender,
cause such Lender and its lending office(s) to suffer no economic, legal or
regulatory disadvantage, and provided, further, that nothing in this subsection
2.18 shall affect or postpone any of the obligations of any Borrower or the
rights of any Lender pursuant to subsection 2.14, 2.15(a) or 2.17.

                  2.19 Extension of Revolving Termination Date. (a) The Borrower
may, by written notice to the Administrative Agent (such notice being an
"Extension Notice") given no earlier than sixty days prior to the Revolving
Termination Date, request the Lenders to consider an extension of the then
applicable Revolving Termination Date to a date which is 364 days after the then
applicable Revolving Termination Date. The Administrative Agent shall promptly
transmit any Extension Notice to each Lender. Each Lender shall notify the
Administrative Agent whether it wishes to extend the then applicable Revolving
Termination Date no earlier than 30 days, and no later than 15 days, prior to
the Revolving Termination Date, and any such notice given by a Lender to the
Administrative Agent, once given, shall be irrevocable as to such Lender. Any
Lender which does not expressly notify the Administrative Agent no earlier than
30 days, and no later than 15 days, prior to the Revolving Termination Date that
it wishes to so extend the then applicable Revolving Termination Date shall be
deemed to have rejected the Borrower's request for extension of such Revolving
Termination Date. Lenders consenting to extend the then applicable Revolving
Termination Date are hereinafter referred to as "Continuing Lenders", and
Lenders declining to consent to extend such Revolving Termination Date (or
Lenders deemed to have so declined) are hereinafter referred to as "Non-
Extending Lenders". If Lenders holding not less than 80% of the Revolving
Commitments then in effect have elected (in their sole and absolute discretion)
to so extend the Revolving Termination Date, the

                                       28
<PAGE>   34

Administrative Agent shall notify the Borrower of such election by such Lenders,
and effective on the date of such notice by the Administrative Agent to the
Borrower, the Revolving Termination Date shall be automatically and immediately
so extended with respect to all Continuing Lenders. Upon the delivery of an
Extension Notice and upon the extension of the Revolving Termination Date
pursuant to this subsection, the Borrower shall be deemed to have represented
and warranted on and as of the date of such Extension Notice and the effective
date of such extension, as the case may be, that no Default or Event of Default
has occurred and is continuing. Notwithstanding anything contained in this
Agreement to the contrary, no Lender shall have any obligation to extend the
Revolving Termination Date, and each Lender may at its option, unconditionally
and without cause, decline to extend the Revolving Termination Date.

                  (b) If the Revolving Termination Date shall have been extended
in accordance with this subsection, all references herein to the "Revolving
Termination Date" shall refer to the Revolving Termination Date as so extended.

                  (c) If any Lender shall determine not to extend the Revolving
Termination Date as requested by any Extension Notice given by the Borrower
pursuant to this subsection, the Revolving Commitment of such Lender shall
terminate on the Revolving Termination Date without giving any effect to such
proposed extension, and the Borrower shall on such date pay to the
Administrative Agent, for the account of such Lender, the principal amount of,
and accrued interest on, such Lender's Loans, together with any amounts payable
to such Lender pursuant to Sections 2.14, 2.15 and 2.16 and any fees or other
amounts owing to such Lender under this Agreement; provided that if such
Non-Extending Lender has been replaced pursuant to paragraph (d) below then the
provisions of such paragraph (d) shall apply. The Total Revolving Commitment
shall be reduced by the amount of the Revolving Commitment of such Non-Extending
Lender to the extent the Revolving Commitment of such Non-Extending Lender has
not been transferred to one or more Continuing Lenders pursuant to paragraph (d)
below.

                  (d) A Non-Extending Lender shall be obligated, at the request
of the Borrower and subject to payment by the Borrower to the Administrative
Agent, for the account of such Non-Extending Lender, of the principal amount of,
and accrued interest on, such Lender's Loans, together with any amounts payable
to such Lender pursuant to Sections 2.14, 2.15 and 2.16 and any fees or other
amounts owing to such Lender under this Agreement, to transfer without recourse,
representation, warranty (other than good title to its Loans) or expense to such
Non-Extending Lender, at any time prior to the Revolving Termination Date
applicable to such Non-Extending Lender, all of its rights (except those which
by their terms survive termination) and obligations hereunder to another
financial institution or group of financial institutions selected by the
Borrower in consultation with the Administrative Agent and willing to
participate in the facility in the place of such Non-Extending Lender; provided
that, if such transferee is not a Lender, such transferee(s) satisfies all the
requirements of this Agreement and the Administrative Agent and the Borrower
each shall have consented to such transfer, which consent shall not be
unreasonably withheld. Each such transferee shall become a Continuing Lender
hereunder in replacement of the Non-Extending Lender and shall enjoy all rights
and assume all obligations on the part of the Lenders set forth in this
Agreement. Simultaneously with such transfer, each

                                       29
<PAGE>   35

such transferee shall execute and deliver to the Administrative Agent an
Assignment and Acceptance assuming all obligations of the Lenders set forth in
this Agreement.

                  (e) If the Revolving Termination Date shall have been extended
in respect of Continuing Lenders in accordance with Section 2.19(a), any notice
of borrowing pursuant to Section 2.2 specifying a Borrowing Date occurring after
the Revolving Termination Date applicable to a Non-Extending Lender or
requesting an Interest Period extending beyond such date shall (a) have no
effect in respect of such Non-Extending Lender and (b) not specify a requested
aggregate principal amount exceeding the aggregate Available Revolving
Commitment (calculated on the basis of the Revolving Commitments of the
Continuing Lenders).

                          SECTION 3. LETTERS OF CREDIT

                  3.1 L/C Commitment. (a) Subject to the terms and conditions
hereof and in reliance on the agreements of the other Lenders set forth in
subsection 3.4(a), each Issuing Lender agrees to issue letters of credit (the
"Letters of Credit") for the account of the Borrower on any Business Day during
the Revolving Commitment Period in such form as may be approved from time to
time by such Issuing Lender; provided, that an Issuing Lender shall have no
obligation to issue any Letter of Credit if, after giving effect to such
issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the
aggregate amount of the Available Revolving Commitments would be less than zero.
Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no
later than the Revolving Termination Date.

                  (b) Each Letter of Credit shall be subject to the Uniform
Customs and, to the extent not inconsistent therewith, the laws of the State of
New York.

                  (c) An Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would violate or cause
violation by such Issuing Lender or any L/C Participant of any limits imposed by
any applicable Requirement of Law (exclusive of any organizational or governance
document of any Lender or Agent) imposed after the Closing Date.

                  3.2 Procedure for Issuance of Letter of Credit. The Borrower
may from time to time request that an Issuing Lender issue a Letter of Credit by
delivering to such Issuing Lender at its address for notices specified herein an
Application therefor, completed to the satisfaction of such Issuing Lender, and
such other certificates, documents and other papers and information as such
Issuing Lender may request. Upon receipt of any Application, an Issuing Lender
will process such Application and the certificates, documents and other papers
and information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall an Issuing Lender be required to issue any Letter
of Credit earlier than one Business Day after its receipt of the Application
therefor and all such other certificates, documents and other papers and
information relating thereto) by issuing the original of such Letter of Credit
to the beneficiary thereof or as otherwise may be agreed to by such Issuing
Lender and the Borrower. Each Issuing Lender shall furnish a copy of such Letter
of Credit to the Borrower promptly following the issuance thereof. Each Issuing
Lender shall promptly furnish to the Administrative Agent, which

                                       30
<PAGE>   36

shall in turn promptly furnish to the Lenders, notice of the issuance of each
Letter of Credit issued by it (including the amount thereof).

                  3.3 Fees and Other Charges. (a) The Borrower will pay (i) to
the Administrative Agent, for the account of the Lenders, a fee with respect to
each outstanding Letter of Credit at a per annum rate equal to the Applicable
Margin then in effect with respect to Eurodollar Loans minus the fronting fee
referred to in clause (ii) below and (ii) to the relevant Issuing Lender for its
own account with respect to each outstanding Letter of Credit a fronting fee
calculated at a rate per annum equal to 0.125%; all such fees in respect of each
Letter of Credit shall be calculated on the face amount thereof for the actual
number of days outstanding and the actual amounts outstanding (provided that in
no event shall the fronting fee for any Letter of Credit be less than $300), and
shall be payable quarterly in arrears on each L/C Fee Payment Date after the
issuance date of such Letters of Credit.

                  (b) In addition to the foregoing fees, the Borrower shall pay
or reimburse each Issuing Lender for its own account for such normal and
customary costs and expenses as are incurred or charged by such Issuing Lender
in negotiating, effecting payment under, amending or otherwise administering any
Letter of Credit.

                  3.4 L/C Participations. (a) Effective on the date of issuance
thereof, each Issuing Lender irrevocably agrees to grant and hereby grants to
each L/C Participant, and, to induce such Issuing Lenders to issue Letters of
Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase
and hereby accepts and purchases from each Issuing Lender, on the terms and
conditions hereinafter stated, for such L/C Participant's own account and risk
an undivided interest equal to such L/C Participant's Revolving Percentage in
such Issuing Lender's obligations and rights under each Letter of Credit issued
hereunder and the amount of each draft paid by such Issuing Lender thereunder in
accordance with the terms of this Agreement. Notwithstanding the provisions
contained in the next to last sentence of subsection 3.5, each L/C Participant
unconditionally and irrevocably agrees with each Issuing Lender that, if a draft
is paid under any Letter of Credit issued by such Issuing Lender for which such
Issuing Lender is not reimbursed in full by the Borrower for all Reimbursement
Obligations in accordance with the terms of this Agreement, such L/C Participant
shall pay to such Issuing Lender upon demand at such Issuing Lender's address
for notices specified herein an amount equal to such L/C Participant's Revolving
Percentage of the amount of such draft, or any part thereof, which is not so
reimbursed.

                  (b) If any amount required to be paid by any L/C Participant
to an Issuing Lender pursuant to subsection 3.4(a) in respect of any
unreimbursed portion of any payment made by such Issuing Lender under any Letter
of Credit is paid to such Issuing Lender within three Business Days after the
date such payment is due, such L/C Participant shall pay to such Issuing Lender
on demand an amount equal to the product of (i) such amount, times (ii) the
daily average Federal Funds Effective Rate during the period from and including
the date such payment is required to the date on which such payment is
immediately available to such Issuing Lender, times (iii) a fraction the
numerator of which is the number of days that elapse during such period and the
denominator of which is 360. If any such amount required to be paid by any

                                       31
<PAGE>   37

L/C Participant pursuant to subsection 3.4(a) is not made available to the
relevant Issuing Lender by such L/C Participant within three Business Days after
the date such payment is due, such Issuing Lender shall be entitled to recover
from such L/C Participant, on demand, such amount with interest thereon
calculated from such due date at the rate per annum applicable to Base Rate
Loans under the Revolving Facility. A certificate of an Issuing Lender submitted
to any L/C Participant with respect to any amounts owing under this subsection
3.4(b) shall be conclusive in the absence of manifest error.

                  (c) Whenever, at any time after an Issuing Lender has made
payment under any Letter of Credit and has received from any L/C Participant its
pro rata share of such payment in accordance with subsection 3.4(a), such
Issuing Lender receives any payment related to such Letter of Credit (whether
directly from the Borrower or otherwise, including proceeds of collateral
applied thereto by such Issuing Lender), or any payment of interest on account
thereof, such Issuing Lender will distribute to such L/C Participant its pro
rata share thereof; provided, however, that in the event that any such payment
received by such Issuing Lender shall be required to be returned by such Issuing
Lender, such L/C Participant shall immediately return to such Issuing Lender the
portion thereof previously distributed by such Issuing Lender to it.

                  3.5 Reimbursement Obligation of the Borrower. The Borrower
agrees to reimburse the relevant Issuing Lender on each date on which such
Issuing Lender notifies the Borrower of the date and amount of a draft presented
under any unexpired Letter of Credit and paid by such Issuing Lender for the
amount of (a) such draft so paid and (b) any costs or expenses provided for in
subsection 3.3(b) which are incurred by such Issuing Lender in connection with
such payment. Each such payment shall be made to the relevant Issuing Lender at
its address for notices specified herein in lawful money of the United States of
America and in immediately available funds. Interest shall be payable on any and
all amounts remaining unpaid by the Borrower under this subsection 3.5 from the
date such amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the rate set forth in (i) until the second
Business Day following the date of the applicable drawing, subsection 2.10(b)
and (ii) thereafter, subsection 2.10(c). Each drawing under any Letter of Credit
shall (unless an event of the type described in clause (i) or (ii) of subsection
8(f) shall have occurred and be continuing with respect to the Borrower, in
which case the procedures specified in subsection 3.4 for funding by L/C
Participants shall apply) constitute a request by the Borrower to the
Administrative Agent for a borrowing pursuant to subsection 2.2 of Base Rate
Loans in the amount of such drawing plus interest and expenses incurred by the
relevant Issuing Lender. The Borrowing Date with respect to such borrowing shall
be the date of such drawing and all proceeds of such borrowing shall be paid to
the relevant Issuing Lender.

                  3.6 Obligations Absolute. The Borrower's obligations under
this Section 3 shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
which the Borrower may have or have had against any Issuing Lender, any
beneficiary of a Letter of Credit or any other Person; provided, that in
honoring each Letter of Credit, such Issuing Lender has acted in good faith and
has examined such Letter of Credit and the accompanying document or documents,
as the case may be, with such care as to ascertain that on their face they
appear to comply with the terms of such Letter of

                                       32
<PAGE>   38

Credit. The Borrower also agrees with each Issuing Lender, subject to the
proviso contained in the preceding sentence, that such Issuing Lender shall not
be responsible for, and the Borrower's Reimbursement Obligations under
subsection 3.5 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even though such
documents shall in fact prove to be invalid, fraudulent or forged, or any
dispute between or among the Borrower and any beneficiary of any Letter of
Credit or any other party to which such Letter of Credit may be transferred or
any claims whatsoever of the Borrower against any beneficiary of such Letter of
Credit or any such transferee. No Issuing Lender shall be liable for (i) any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such Issuing Lender, (ii) the validity or
sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason, (iii) failure of the beneficiary of any
such Letter of Credit to comply fully with conditions required in order to draw
upon such Letter of Credit, which failure is not the result of gross negligence
or willful misconduct of such Issuing Lender as determined by a final and
nonappealable decision of a court of competent jurisdiction, (iv) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing thereunder and (v) any consequences arising from causes beyond
the control of such Issuing Lender, including, without limitation, the actions
of any Governmental Authority. The Borrower agrees that any action taken or
omitted by such Issuing Lender under or in connection with any Letter of Credit
or the related drafts or documents, if done in the absence of gross negligence
or willful misconduct and in accordance with the standards or care specified in
the Uniform Commercial Code of the State of New York, shall be binding on the
Borrower and shall not result in any liability of such Issuing Lender to the
Borrower.

                  3.7 Letter of Credit Payments. If any draft shall be presented
for payment under any Letter of Credit, the relevant Issuing Lender shall
promptly notify the Borrower of the date and amount thereof. The responsibility
of an Issuing Lender to the Borrower in connection with any draft presented for
payment under any Letter of Credit issued by such Issuing Lender shall, in
addition to any payment obligation expressly provided for in such Letter of
Credit, be limited to determining that the documents (including each draft)
delivered under such Letter of Credit in connection with such presentment are
substantially in conformity with such Letter of Credit and appear on their face
to comply with such Letter of Credit.

                  3.8 Applications. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                  3.9 Indemnification of Issuing Lender. To the extent the
relevant Issuing Lender is not reimbursed and indemnified by the Borrower, each
Lender will reimburse and indemnify such Issuing Lender in proportion to its
Revolving Percentage, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs,

                                       33
<PAGE>   39

expenses (including counsel fees and disbursements) or disbursements of any kind
or nature whatsoever which may be imposed on, incurred by or asserted against
such Issuing Lender in performing its duties hereunder, in any way relating to
or arising out of this Agreement and by reason of the ordinary negligence of
such Issuing Lender; provided that no Lender shall be liable to such Issuing
Lender for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Issuing Lender's gross negligence or willful misconduct. The
provisions of this subsection 3.9 shall survive any termination of this
Agreement and the payment of the Obligations and shall continue thereafter in
full force and effect.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To induce the Agents and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit, the Borrower hereby represents and warrants to each Agent and each
Lender that:

                  4.1 Financial Condition. The audited consolidated balance
sheet of the Borrower and its consolidated Subsidiaries as at December 31, 1999,
and the related consolidated statements of income and of cash flows for the
fiscal year ended on such date, reported on by and accompanied by an unqualified
report from Deloitte & Touche LLP, present fairly the consolidated financial
condition of the Borrower and its consolidated Subsidiaries as at such date, and
the consolidated results of its operations and its consolidated cash flows for
the fiscal year then ended. The unaudited consolidated balance sheet of the
Borrower and its consolidated Subsidiaries as at June 30, 2000, and the related
unaudited consolidated statements of income and cash flows for the six-month
period ended on such date, present fairly the consolidated financial condition
of the Borrower and its consolidated Subsidiaries as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
six -month period then ended (subject to normal year-end audit adjustments). All
such financial statements, including the related schedules and notes thereto,
have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein). The Borrower and its Subsidiaries do not have any
material Guarantee Obligations, contingent liabilities and liabilities for
taxes, or any long-term leases or unusual forward or long-term commitments,
including, without limitation, any interest rate or foreign currency swap or
exchange transaction or other obligation in respect of derivatives, that are not
reflected in the most recent financial statements referred to in this paragraph.
During the period from December 31, 1999 to and including the date hereof there
has been no Disposition by the Borrower and its consolidated Subsidiaries of any
material part of its business or Property.

                  4.2 No Change. Since December 31, 1999 there has been no
development or event which has had or could reasonably be expected to have a
Material Adverse Effect.

                  4.3 Corporate Existence; Compliance with Law. Each of the
Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to

                                       34
<PAGE>   40

own and operate its Property, to lease the Property it operates as lessee and to
conduct the business in which it is currently engaged, (c) is duly qualified as
a foreign corporation and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of Property or the conduct of its
business requires such qualification, except where the failure to be so
qualified and in good standing could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect.

                  4.4 Corporate Power; Authorization; Enforceable Obligations.
Each Loan Party has the corporate power and authority, and the legal right, to
make, deliver and perform the Loan Documents to which it is a party and, in the
case of the Borrower, to borrow hereunder. Each Loan Party has taken all
necessary corporate action to authorize the execution, delivery and performance
of the Loan Documents to which it is a party and, in the case of the Borrower,
to authorize the borrowings on the terms and conditions of this Agreement. No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement or any of the Loan
Documents, except (i) consents, authorizations, filings and notices described in
Schedule 4.4, which consents, authorizations, filings and notices have been
obtained or made and are in full force and effect (except as noted in Schedule
4.4), and (ii) any consent that may be required to be obtained by or on behalf
of any Lender. Each Loan Document has been duly executed and delivered on behalf
of each Loan Party party thereto. This Agreement constitutes, and each other
Loan Document upon execution will constitute, a legal, valid and binding
obligation of each Loan Party party thereto, enforceable against each such Loan
Party in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

                  4.5 No Legal Bar. The execution, delivery and performance of
this Agreement and the other Loan Documents, the issuance of Letters of Credit,
the borrowings hereunder and the use of the proceeds thereof will not violate
any Requirement of Law applicable to, or any material Contractual Obligation of,
the Borrower or any of its Subsidiaries and will not result in, or require, the
creation or imposition of any Lien on any of their respective properties or
revenues pursuant to any Requirement of Law or any such Contractual Obligation.
No Requirement of Law or Contractual Obligation applicable to the Borrower or
any of its Subsidiaries could reasonably be expected to have a Material Adverse
Effect.

                  4.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of their respective properties or revenues
(a) with respect to any of the Loan Documents or any of the transactions
contemplated hereby or thereby or (b) which could reasonably be expected to have
a Material Adverse Effect.

                                       35
<PAGE>   41

                  4.7 No Default. Neither the Borrower nor any of its
Subsidiaries is in default of its Contractual Obligations in any respect which
could reasonably be expected to have a Material Adverse Effect. No Default or
Event of Default has occurred and is continuing.

                  4.8 Ownership of Property; Liens. Each of the Borrower and its
Subsidiaries has indefeasible title to, or a valid leasehold interest in, all of
its material real property, and good title to, or a valid leasehold interest in,
all its other material Property, and none of such Property is subject to any
Lien except as permitted by subsection 7.3.

                  4.9 Intellectual Property. The Borrower and each of its
Subsidiaries owns, or is licensed to use, all Intellectual Property necessary
for the conduct of its business as currently conducted. No material claim has
been asserted and is pending against the Borrower or any of its Subsidiaries by
any Person challenging or questioning the use of any such Intellectual Property
by the Borrower or any of its Subsidiaries or the validity or effectiveness of
any such Intellectual Property, nor does the Borrower know of any valid basis
for any such claim. The use of such Intellectual Property by the Borrower and
its Subsidiaries does not infringe on the rights of any Person known by the
Borrower to have a legal right therein.

                  4.10 Taxes. Each of the Borrower and its Subsidiaries has
filed or caused to be filed all Federal, state and other material tax returns
which are required to be filed and has paid all taxes shown to be due and
payable on said returns or on any assessments made against it or any of its
Property and all other taxes, fees or other charges imposed on it or any of its
Property by any Governmental Authority, and no tax Lien has been filed, and, to
the knowledge of the Borrower, no claim which could reasonably be expected to
have a Material Adverse Effect is being asserted, with respect to any such tax,
fee or other charge (other than any such claim the amount or validity of which
is currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or its Subsidiaries, as the case may be).

                  4.11 Federal Regulations. No part of the proceeds of any Loans
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U as now and
from time to time hereafter in effect or for any purpose which violates the
provisions of the Regulations of the Board. 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 G-3 or FR Form U-1 referred to in Regulation U.

                  4.12 Labor Matters. There are no strikes or other labor
disputes against the Borrower or any of its Subsidiaries pending or, to the
knowledge of the Borrower, threatened that (individually or in the aggregate)
could reasonably be expected to have a Material Adverse Effect. Hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the

                                       36

<PAGE>   42
aggregate) could reasonably be expected to have a Material Adverse Effect if not
paid have been paid or accrued as a liability on the books of the Borrower or
the relevant Subsidiary.

                  4.13 ERISA. Except as set forth on Schedule 4.13, neither a
Reportable Event nor an "accumulated funding deficiency" (within the meaning of
Section 412 of the Code or Section 302 of ERISA) has occurred during the
five-year period prior to the date on which this representation is made or
deemed made with respect to any Plan, and each Plan has complied in all material
respects with the applicable provisions of ERISA and the Code. No termination of
a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan
has arisen, during such five-year period. The present value of all accrued
benefits under each Single Employer Plan (based on those assumptions used to
fund such Plans) did not, as of the last annual valuation date prior to the date
on which this representation is made or deemed made, exceed the value of the
assets of such Plan allocable to such accrued benefits by a material amount.
Neither the Borrower nor any Commonly Controlled Entity has had a complete or
partial withdrawal from any Multiemployer Plan which has resulted or could
reasonably be expected to result in a material liability under ERISA, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any material liability under ERISA if the Borrower or any such Commonly
Controlled Entity were to withdraw completely from all Multiemployer Plans as of
the valuation date most closely preceding the date on which this representation
is made or deemed made. No such Multiemployer Plan is in Reorganization or
Insolvent.

                  4.14 Investment Company Act; Other Regulations. No Loan Party
is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

                  4.15 Subsidiaries. The Subsidiaries listed on Schedule 4.15
constitute all the Subsidiaries of the Borrower at the date hereof.

                  4.16 Use of Proceeds. The proceeds of the Loans shall be used
to refinance certain existing Indebtedness of the Borrower and its Subsidiaries,
to provide for ongoing working capital, capital expenditures and general
corporate needs and the issuance of letters of credit.

                  4.17 Environmental Matters.

                  (a) Other than exceptions to any of the following that could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, the Borrower and each of its Subsidiaries: (i) is, and within
the period of all applicable statutes of limitation has been, in compliance with
all applicable Environmental Laws; (ii) holds all Environmental Permits (each of
which is in full force and effect) required for any of its current operations or
for any property owned, leased, or otherwise operated by it; (iii) is, and
within the period of all applicable statutes of limitation has been, in
compliance with all of its Environmental Permits; and (iv) reasonably believes
that: each of its Environmental Permits will be timely renewed and

                                       37
<PAGE>   43

complied with, without material expense; any additional Environmental Permits
that may be required of any of it will be timely obtained and complied with,
without material expense; and compliance with any Environmental Law that is or
is expected to become applicable to it will be timely attained and maintained.

                  (b) The presence of Materials of Environmental Concern at, on,
under, in, or about any real property now owned, leased or operated by the
Borrower or any of its Subsidiaries, or at any location to which Materials of
Environmental Concern have been sent by or on behalf of the Borrower for re-use
or recycling or for treatment, storage, or disposal, could not reasonably be
expected to have a Material Adverse Effect. The Borrower has not received any
notice from any Governmental Authority or any Person having a property interest
in the relevant property that would give the Borrower reason to believe that the
presence of Materials of Environmental Concern at, on, under, in, or about any
real property formerly owned, leased or operated by the Borrower or any of its
Subsidiaries, could reasonably be expected to have a Material Adverse Effect.

                  (c) Other than exceptions to any of the following that could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: there is no judicial, administrative, or arbitral proceeding
(including any notice of violation or alleged violation) under or relating to
any Environmental Law to which the Borrower or any of its Subsidiaries is, or to
the knowledge of any of them will be, named as a party that is pending or, to
the knowledge of any of them, threatened.

                  (d) Other than exceptions to any of the following that could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: neither the Borrower nor any of its Subsidiaries has received
any request for information or been notified that it is a potentially
responsible party under or relating to the federal Comprehensive Environmental
Response, Compensation, and Liability Act or any similar Environmental Law, or
with respect to any Materials of Environmental Concern.

                  (e) Other than exceptions to any of the following that could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: neither the Borrower nor any of its Subsidiaries has entered
into or agreed to any consent decree, order, or settlement or other agreement,
nor is subject to any judgment, decree, or order or other agreement, in any
judicial, administrative, arbitral, or other forum, relating to compliance with
or liability under any Environmental Law.

                  (f) Other than exceptions to any of the following that could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect: neither the Borrower nor any of its Subsidiaries has assumed or
retained, by contract or operation of law, any liabilities of any kind, fixed or
contingent, known or unknown, under any Environmental Law or with respect to any
Materials of Environmental Concern.

                  4.18 Accuracy of Information, etc. No statement or information
contained in this Agreement, any other Loan Document or any other document,
certificate or statement furnished to the Administrative Agent or the Lenders or
any of them, by or on behalf of any

<PAGE>   44

Loan Party for use in connection with the transactions contemplated by this
Agreement or the other Loan Documents, contained as of the date such statement,
information, document or certificate was so furnished, any untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements contained herein or therein not misleading. The projections and pro
forma financial information contained in the materials referenced above are
based upon good faith estimates and assumptions believed by management of the
Borrower to be reasonable at the time made, it being recognized by the Lenders
that such financial information as it relates to future events is not to be
viewed as fact and that actual results during the period or periods covered by
such financial information may differ from the projected results set forth
therein by a material amount. There is no fact known to any Loan Party that
could reasonably be expected to have a Material Adverse Effect that has not been
expressly disclosed herein, in the other Loan Documents or in any other
documents, certificates and statements furnished to the Administrative Agent and
the Lenders for use in connection with the transactions contemplated hereby and
by the other Loan Documents.

                  4.19 Solvency. Each Loan Party is, and after giving effect to
the incurrence of all Indebtedness and obligations being incurred in connection
herewith will be and will continue to be, Solvent.

                  4.20 Senior Indebtedness. The Obligations will constitute
"Senior Debt" of the Borrower within the meaning of the Senior Subordinated Note
Indenture. The obligations of each Subsidiary Guarantor under the Guarantee
Agreement constitute "Senior Debt" of such Subsidiary Guarantor within the
meaning of the Senior Subordinated Note Indenture. The Obligations will
constitute "Designated Senior Debt" for purposes of the Senior Subordinated Note
Indenture (and, to the extent necessary, the Borrower hereby designates, for
purposes of the Senior Subordinated Note Indenture, the Obligations as
"Designated Senior Debt").

                  4.21 Excluded Subsidiaries. The aggregate book value of the
assets of all Excluded Subsidiaries on the date hereof does not exceed
$2,500,000 in the aggregate.

the same or a similar business, through self-insurance) insurance on all its
Property in at least such amounts and against at least such risks (but including

                  6.6 Inspection of Property; Books and Records; Discussions.
(a) Keep proper books of records and accounts in which full, true and correct
entries in conformity with GAAP and all Requirements of Law applicable to it
shall be made of all dealings and transactions in relation to its business and
activities and (b) permit representatives of any Lender to visit and inspect any
of its properties and examine and make abstracts from any of its books and
records at any reasonable time during normal business hours and as often as may
reasonably be desired and to discuss the business, operations, properties and
financial and other condition of the Borrower and its Subsidiaries with officers

involving any Plan, (ii) any "accumulated funding deficiency" (as defined in
Section 302 of ERISA), whether or not waived, shall exist with respect to any

Borrower or any Commonly Controlled Entity, (iii) a Reportable Event shall occur
with respect to, or proceedings shall commence to have a trustee appointed, or a

and in each case in clauses (i) through (vi) above, such event or condition,

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Revolving Commitments shall immediately terminate and the
Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement and the other Loan Documents (including, without
limitation, all amounts of L/C Obligations, whether or not the beneficiaries of
the then outstanding Letters of Credit shall have presented the documents
required thereunder) shall immediately become due and payable, and (B) if such
event is any other Event of Default, either or both of the following actions may
be taken, so long as such Event of Default is in existence and has not otherwise

Majority Lenders, the Administrative Agent shall, by notice to the Borrower
declare the Revolving Commitments to be terminated forthwith, whereupon the
Revolving Commitments shall immediately terminate; and (ii) with the consent of
the Required Lenders, the Administrative Agent may, or upon the request of the

Credit with respect to which presentment for honor shall not have occurred at
the time of an acceleration pursuant to this paragraph, the Borrower shall at
such time deposit in a cash collateral account opened by the Administrative
Agent an amount equal to the aggregate then undrawn and unexpired amount of such
Letters of Credit. Amounts held in such cash collateral account shall be applied
by the Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to the Borrower (or such other Person as may be lawfully entitled thereto).

                      SECTION 9. THE ADMINISTRATIVE AGENT

                  9.1 Appointment; Nature of Relationship. Bank One, NA is
hereby appointed by each of the Lenders as its contractual representative
(herein referred to as the "Administrative Agent") hereunder and under each
other Loan Document, and each of the Lenders irrevocably authorizes the
Administrative Agent to act as the contractual representative of such Lender
with

                                       53
<PAGE>   59

the rights and duties expressly set forth herein and in the other Loan
Documents. The Administrative Agent agrees to act as such contractual
representative upon the express conditions contained in this Section 9.
Notwithstanding the use of the defined term "Administrative Agent," it is
expressly understood and agreed that the Administrative Agent shall not have any
fiduciary responsibilities to any Lender by reason of this Agreement or any
other Loan Document and that the Administrative Agent is merely acting as the
contractual representative of the Lenders with only those duties as are
expressly set forth in this Agreement and the other Loan Documents. In its
capacity as the Lenders' contractual representative, the Administrative Agent
(i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a
"representative" of the Lenders within the meaning of Section 9-105 of the
Uniform Commercial Code and (iii) is acting as an independent contractor, the
rights and duties of which are limited to those expressly set forth in this
Agreement and the other Loan Documents. Each of the Lenders hereby agrees to
assert no claim against the Administrative Agent on any agency theory or any
other theory of liability for breach of fiduciary duty, all of which claims each
Lender hereby waives.

                  9.2 Powers. The Administrative Agent shall have and may
exercise such powers under the Loan Documents as are specifically delegated to
the Administrative Agent by the terms of each thereof, together with such powers
as are reasonably incidental thereto. The Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Administrative Agent.

                  9.3 General Immunity. Neither the Administrative Agent nor any
of its directors, officers, agents or employees shall be liable to the Lenders
or any Lender for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or
therewith except to the extent such action or inaction is determined in a final
non-appealable judgment by a court of competent jurisdiction to have arisen from
the gross negligence or willful misconduct of such Person.

                  9.4 No Responsibility for Loans, Recitals, etc.. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify
(a) any statement, warranty or representation made in connection with any Loan
Document or any borrowing hereunder; (b) the performance or observance of any of
the covenants or agreements of any obligor under any Loan Document, including,
without limitation, any agreement by an obligor to furnish information directly
to each Lender; (c) the satisfaction of any condition specified in Section 5,
except receipt of items required to be delivered solely to the Administrative
Agent; (d) the existence or possible existence of any Default or Event of
Default; (e) the validity, enforceability, effectiveness, sufficiency or
genuineness of any Loan Document or any other instrument or writing furnished in
connection therewith; (f) the value, sufficiency, creation, perfection or
priority of any Lien in any collateral security; or (g) the financial condition
of the Borrower or any guarantor of any of the Obligations or of any of the
Borrower's or any such guarantor's respective Subsidiaries. The Administrative
Agent shall have no duty to disclose to the Lenders information that is not
required to be furnished by the Borrower to the Administrative Agent at such
time, but is

                                       54
<PAGE>   60

voluntarily furnished by the Borrower to the Administrative Agent (either in its
capacity as Administrative Agent or in its individual capacity).

                  9.5 Action on Instructions of Lenders. The Administrative
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders (or all Lenders, in the case of
actions which, pursuant to subsection 10.1, require the consent of all Lenders),
and such instructions and any action taken or failure to act pursuant thereto
shall be binding on all of the Lenders. The Lenders hereby acknowledge that the
Administrative Agent shall be under no duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement or any
other Loan Document unless it shall be requested in writing to do so by the
Required Lenders (or all Lenders, in the case of actions which, pursuant to
subsection 10.1, require the consent of all Lenders). The Administrative Agent
shall be fully justified in failing or refusing to take any action hereunder and
under any other Loan Document unless it shall first be indemnified to its
satisfaction by the Lenders pro rata against any and all liability, cost and
expense that it may incur by reason of taking or continuing to take any such
action.

                  9.6 Employment of Agents and Counsel. The Administrative Agent
may execute any of its duties as Administrative Agent hereunder and under any
other Loan Document by or through employees, agents, and attorneys-in-fact and
shall not be answerable to the Lenders, except as to money or securities
received by it or its authorized agents, for the default or misconduct of any
such agents or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall be entitled to advice of counsel concerning the
contractual arrangement between the Administrative Agent and the Lenders and all
matters pertaining to the Administrative Agent's duties hereunder and under any
other Loan Document.

                  9.7 Reliance on Documents; Counsel. The Administrative Agent
shall be entitled to rely upon any Note, notice, consent, certificate,
affidavit, letter, telegram, statement, paper or document believed by it to be
genuine and correct and to have been signed or sent by the proper person or
persons, and, in respect to legal matters, upon the opinion of counsel selected
by the Administrative Agent, which counsel may be employees of the
Administrative Agent.

                  9.8 Administrative Agent's Reimbursement and Indemnification.
The Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Revolving Commitments (or, if the Revolving
Commitments have been terminated, in proportion to their Revolving Commitments
immediately prior to such termination) (i) for any amounts not reimbursed by the
Borrower for which the Administrative Agent is entitled to reimbursement by the
Borrower under the Loan Documents, (ii) for any other expenses incurred by the
Administrative Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration and enforcement of the Loan
Documents (including, without limitation, for any expenses incurred by the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders) and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,

                                       55
<PAGE>   61

expenses or disbursements of any kind and nature whatsoever which may be imposed
on, incurred by or asserted against the Administrative Agent in any way relating
to or arising out of the Loan Documents or any other document delivered in
connection therewith or the transactions contemplated thereby (including,
without limitation, for any such amounts incurred by or asserted against the
Administrative Agent in connection with any dispute between the Administrative
Agent and any Lender or between two or more of the Lenders), or the enforcement
of any of the terms of the Loan Documents or of any such other documents,
provided that (i) no Lender shall be liable for any of the foregoing to the
extent any of the foregoing is found in a final non-appealable judgment by a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of the Administrative Agent and (ii) any indemnification
required pursuant to subsection 2.15 shall, notwithstanding the provisions of
this subsection 9.8, be paid by the relevant Lender in accordance with the
provisions thereof. The obligations of the Lenders under this subsection 9.8
shall survive payment of the Obligations and termination of this Agreement.

                  9.9 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 written notice
from a Lender or the Borrower referring to this Agreement 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.

                  9.10 Rights as a Lender. In the event the Administrative Agent
is a Lender, the Administrative Agent shall have the same rights and powers
hereunder and under any other Loan Document with respect to its Revolving
Commitment and its Loans as any Lender and may exercise the same as though it
were not the Administrative Agent, and the term "Lender" or "Lenders" shall, at
any time when the Administrative Agent is a Lender, unless the context otherwise
indicates, include the Administrative Agent in its individual capacity. The
Administrative Agent and its Affiliates may accept deposits from, lend money to,
and generally engage in any kind of trust, debt, equity or other transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Subsidiaries in which the Borrower or such
Subsidiary is not restricted hereby from engaging with any other Person.

                  9.11 Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Agent, the
Arranger or any other Lender and based on the financial statements prepared by
the Borrower and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement and the other Loan Documents. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent, the
Arranger or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents.

                                       56
<PAGE>   62

                  9.12 Successor Administrative Agent. The Administrative Agent
may resign at any time by giving written notice thereof to the Lenders and the
Borrower, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, forty-five days after the retiring Administrative Agent gives notice
of its intention to resign. The Administrative Agent may be removed at any time
with or without cause by written notice received by the Administrative Agent
from the Required Lenders, such removal to be effective on the date specified by
the Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within thirty days after the resigning
Administrative Agent's giving notice of its intention to resign, then the
resigning Administrative Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Administrative Agent. Notwithstanding the previous
sentence, the Administrative Agent may at any time without the consent of the
Borrower or any Lender, appoint any of its Affiliates which is a commercial bank
as a successor Administrative Agent hereunder. If the Administrative Agent has
resigned or been removed and no successor Administrative Agent has been
appointed, the Lenders may perform all the duties of the Administrative Agent
hereunder and the Borrower shall make all payments in respect of the Obligations
to the applicable Lender and for all other purposes shall deal directly with the
Lenders. No successor Administrative Agent shall be deemed to be appointed
hereunder until such successor Administrative Agent has accepted the
appointment. Any such successor Administrative Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent. Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent shall be discharged from its duties and obligations
hereunder and under the Loan Documents and the resigning or removed
Administrative Agent shall pay to the successor Administrative Agent any
unamortized portion of Administrative Agent's fees previously paid to such
resigning or removed Administrative Agent . After the effectiveness of the
resignation or removal of an Administrative Agent, the provisions of this
Section 9 shall continue in effect for the benefit of such Administrative Agent
in respect of any actions taken or omitted to be taken by it while it was acting
as the Administrative Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Administrative Agent by merger, or the
Administrative Agent assigns its duties and obligations to an Affiliate pursuant
to this subsection 9.12, then the term "Prime Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new
Administrative Agent. Any successor Administrative Agent appointed pursuant to
this subsection 9.12 shall (unless an Event of Default under subsection 8(a) or
subsection 8(f) shall have occurred and be continuing) be subject to the
approval of the Borrower (which approval shall not be unreasonably withheld or
delayed).

                  9.13 Delegation to Affiliates. The Borrower and the Lenders
agree that the Administrative Agent may delegate any of its duties under this
Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of

                                       57
<PAGE>   63

the indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Sections 9 and 10.

                  9.14 Documentation Agent, Syndication Agent, etc. Neither any
of the Lenders identified in this Agreement as a "Documentation Agent" or
"Syndication Agent" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of such Lenders shall have
or be deemed to have a fiduciary relationship with any Lender. Each Lender
hereby makes the same acknowledgments with respect to such Lenders as it makes
with respect to the Administrative Agent in subsection 9.11.

                           SECTION 10. MISCELLANEOUS

                  10.1 Amendments and Waivers. Neither this Agreement, any other
Loan Document, nor any terms hereof or thereof may be amended, supplemented or

Required Lenders and each Loan Party party to the relevant Loan Document may, or
(with the written consent of the Required Lenders) the Agents and each Loan
Party party to the relevant Loan Document may, from time to time, (a) enter into
written amendments, supplements or modifications hereto and to the other Loan
Documents for the purpose of adding any provisions to this Agreement or the
other Loan Documents or changing in any manner the rights of the Lenders or of
the Loan Parties hereunder or thereunder or (b) waive, on such terms and
conditions as the Required Lenders, or the Agents, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or the
other Loan Documents or any Default or Event of Default and its consequences;
provided, however, that no such waiver and no such amendment, supplement or
modification shall (i) forgive the principal amount or extend the final
scheduled date of maturity of any Loan or any Reimbursement Obligation, reduce
the stated rate of any interest or fee payable hereunder or extend the scheduled
date of any payment thereof, or increase the amount or extend the expiration

of each Lender directly affected thereby; (ii) amend, modify or waive any
provision of this subsection 10.1 or reduce any percentage specified in the

without the consent of all Lenders; (iii) amend, modify or waive any provision
of Section 9 without the consent of the Agents; or (iv) amend, modify or waive
any provision of Section 3 without the consent of such Issuing Lender. Any such
waiver and any such amendment, supplement or modification shall apply equally to
each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the
Administrative Agent and all future holders of the Loans. In the case of any
waiver, the Loan Parties, the Lenders and the Administrative Agent shall be
restored to their former position and rights hereunder and under the other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon. Any
such waiver, amendment, supplement or modification shall be effected by a
written instrument signed by the parties required to sign pursuant to the
foregoing

in any way used by the Borrower or any of its Subsidiaries (all the foregoing in
this clause (d), collectively, the "Indemnified Liabilities"), provided, that
the Borrower shall have no obligation hereunder to any Indemnitee with respect
to Indemnified Liabilities (i) to the extent such Indemnified Liabilities are
found by a final and nonappealable decision of a court of competent jurisdiction
to have resulted from the gross negligence or willful misconduct of such
Indemnitee or (ii) solely related to the transfer, assignment or other
disposition by or on behalf of any Indemnitee of any Note or any interest in its
Commitments or rights to payment under this Agreement. Without limiting the
foregoing,

                                       60
<PAGE>   66

and to the extent permitted by applicable law, the Borrower agrees not to assert
and to cause its Subsidiaries not to assert, and hereby waives and agrees to
cause its Subsidiaries so to waive, all rights for contribution or any other
rights of recovery with respect to all claims, demands, penalties, fines,
liabilities, settlements, damages, costs and expenses of whatever kind or
nature, under or related to Environmental Laws, that any of them now or
hereafter might have by statute or otherwise against any indemnitee. The
agreements in this subsection 10.5 shall survive repayment of the Loans and all
other amounts payable hereunder.

                  10.6 Successors and Assigns; Participations and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Agents, all future holders of the Loans and their
respective successors and assigns, except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of the Agents and each Lender.

                  (b) Any Lender may, without the consent of the Borrower, in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant") participating interests
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the other Loan Documents, and the
Borrower and the Agents shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and the other Loan Documents. In no event shall any Participant under
any such participation have any right to approve any amendment or waiver of any
provision of any Loan Document, or any consent to any departure by any Loan
Party therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Loans or any fees payable
hereunder, or postpone the date of the final maturity of the Loans, in each case
to the extent subject to such participation. The Borrower agrees that if amounts
outstanding under this Agreement and the Loans are due but unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall, to the maximum extent permitted by
applicable law, be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement, provided that, in purchasing such participating
interest, such Participant shall be deemed to have agreed to share with the
Lenders the proceeds thereof as provided in subsection 10.7(a) as fully as if it
were a Lender hereunder. The Borrower also agrees that each Participant shall be
entitled to the benefits of subsections 2.14, 2.15 and 2.16 with respect to its
participation in the Revolving Commitments and the Loans outstanding from time
to time as if it was a Lender; provided that, in the case of subsection 2.15,
such Participant shall have complied with the requirements of such subsection
and provided, further, that no Participant shall be entitled to receive any
greater amount pursuant to any such subsection than the transferor Lender would
have been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such Participant had no such transfer
occurred.

<PAGE>   67

                  (c) Any Lender (an "Assignor") may, in accordance with
applicable law, at any time and from time to time assign to (i) any Lender or
any affiliate thereof (provided that the consent of such Issuing Lender shall be
obtained in connection with any assignment of Revolving Commitments to an
affiliate of a Lender), (ii) with the consent of the Borrower, the
Administrative Agent and such Issuing Lender, (which, in each case, shall not be
unreasonably withheld or delayed), to an additional bank, financial institution
or other entity (an "Assignee") all or any part of its rights and obligations
under this Agreement pursuant to an Assignment and Acceptance, substantially in
the form of Exhibit D, executed by such Assignee and such Assignor (and, where
the consent of the Borrower, the Administrative Agent or such Issuing Lender is
required pursuant to the foregoing provisions, by the Borrower or the Borrower
and such other Persons, as the case may be) and delivered to the Administrative
Agent for its acceptance and recording in the Register; provided that, unless
otherwise agreed by the Borrower and the Administrative Agent, and except in the
case of an assignment by a Lender of all of its Revolving Commitment and/or
Loans under this Agreement and the Revolving Credit Agreement, (i) no assignment
to an Assignee (other than any Lender or any affiliate thereof) of Revolving
Commitment and/ or Loans under this Agreement shall be in an amount which, when
aggregated with the amount of Revolving Commitment and/ or Loans under (and as
defined in) the Revolving Credit Agreement assigned concurrently with such
assignment hereunder, is less than $5,000,000 and (ii) after giving effect to
any assignment hereunder, the Assignor must have Revolving Commitment and/or
Loans under this Agreement in an amount which, when aggregated with the amount
of Revolving Commitment and/ or Loans of such Assignor under (and as defined in)
the Revolving Credit Agreement, is at least $10,000,000. Each assignment of
Revolving Commitments and/or Loans by a Lender must be accompanied by an
assignment by such Assignor Lender to the same Assignee of a proportionate
amount of such Assignor Lender's Revolving Commitments and/or Loans under (and
as defined in) the Revolving Credit Agreement. Upon such execution, delivery,
acceptance and recording, from and after the effective date determined pursuant
to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party
hereto and, to the extent provided in such Assignment and Acceptance, have the
rights and obligations of a Lender hereunder with a Revolving Commitment and/or
Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of an Assignor's rights and obligations under this Agreement, such Assignor
shall cease to be a party hereto). Notwithstanding any provision of this
subsection 10.6(c), the consent of the Borrower shall not be required for any
assignment which occurs at any time when any Event of Default shall have
occurred and be continuing.

                  (d) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in subsection 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the Revolving
Commitment of, and principal amount of the Loans owing to, each Lender from time
to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, the Administrative Agent and the Lenders shall
treat each Person whose name is recorded in the Register as the owner of the
Loans and any Notes evidencing such Loans recorded therein for all purposes of
this Agreement. Any assignment of any Loan, whether or

                                       62
<PAGE>   68

not evidenced by a Note, shall be effective only upon appropriate entries with
respect thereto being made in the Register (and each Note shall expressly so
provide). Any assignment or transfer of all or part of a Loan evidenced by a
Note shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note evidencing such Loan, accompanied by a duly
executed Assignment and Acceptance; thereupon one or more new Notes in the same
aggregate principal amount shall be issued to the designated Assignee, and the
old Notes shall be returned by the Administrative Agent to the Borrower marked
"cancelled". 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.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an Assignor and an Assignee (and, in any case where the consent of any other
Person is required by subsection 10.6(c), by each such other Person) together
with payment by such Assignor and/or such Assignee (as agreed between them) to
the Administrative Agent of a registration and processing fee of $3,500 (except
that no such registration and processing fee shall be payable in the case of an
Assignee which is already a Lender or is an affiliate of a Lender or a Person
under common management with a Lender), the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give notice of such acceptance and recordation to the Lenders and
the Borrower. On or prior to such effective date, the Borrower, at its own
expense, upon request, shall execute and deliver to the Administrative Agent (in
exchange for the Note of the assigning Lender) a new Note, to the order of such
Assignee in an amount equal to the Revolving Commitment assumed or acquired by
it pursuant to such Assignment and Acceptance and, if the Assignor has retained
a Revolving Commitment, upon request, a new Note, to the order of the Assignor
in an amount equal to the Revolving Commitment, retained by it hereunder. Such
new Note or Notes shall be dated the Closing Date and shall otherwise be in the
form of the Note or Notes replaced thereby.

                  (f) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection 10.6 concerning assignments
of Loans and Notes relate only to absolute assignments and that such provisions
do not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law; provided, that all
related costs, fees and expenses assessed against or incurred by such Lender
solely in connection with any such assignment to any Federal Reserve Bank or any
related re-assignment to such Lender shall be for the sole account of such
Lender.

                  10.7 Adjustments; Set-off. (a) If any Lender (a "Benefitted
Lender") shall at any time receive any payment of all or part of the Obligations
owing to it, or receive any collateral in respect thereof (whether voluntarily
or involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in subsection 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's Obligations, such Benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Obligations, or shall provide such other Lenders with the
benefits of any such collateral, as shall be necessary to cause

                                       63
<PAGE>   69

such Benefitted Lender to share the excess payment or benefits of such
collateral ratably with each of the Lenders; provided, however, that if all or
any portion of such excess payment or benefits is thereafter recovered from such
Benefitted Lender, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest.

                  (b) In addition to any rights and remedies of the Lenders
provided by law, at any time when an Event of Default is in existence, each
Lender shall have the right, without prior notice to the Borrower, any such
notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise), to set
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency thereof to or for the
credit or the account of the Borrower, as the case may be. Each Lender agrees
promptly to notify the Borrower and the Administrative Agent after any such
setoff and application made by such Lender, provided that the failure to give
such notice shall not affect the validity of such setoff and application.

                  10.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument. Delivery of an executed signature page of this
Agreement by facsimile transmission shall be effective as delivery of a manually
executed counterpart hereof. A set of the copies of this Agreement signed by all
the parties shall be lodged with the Borrower and the Administrative Agent.

                  10.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  10.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Agents and the Lenders with respect
to the subject matter hereof, and there are no promises, undertakings,
representations or warranties by any Agent or any Lender relative to subject
matter hereof not expressly set forth or referred to herein or, in the other
Loan Documents.

                  10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  10.12 Submission To Jurisdiction; Waivers (a) The Borrower
hereby irrevocably and unconditionally:

                                       64
<PAGE>   70

                  (i)      submits for itself and its Property in any legal
         action or proceeding relating to this Agreement and the other Loan
         Documents to which it is a party, or for recognition and enforcement of
         any judgment in respect thereof, to the non-exclusive general
         jurisdiction of the courts of the State of New York, the courts of the
         United States of America for the Southern District of New York, and
         appellate courts from any thereof;

                  (ii)     consents that any such action or proceeding may be
         brought in such courts and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same;

                  (iii)    agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to the Borrower at its address set forth in subsection 10.2 or
         at such other address of which the Administrative Agent shall have been
         notified pursuant thereto; and

                  (iv)     agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction.

                  (b) Each party hereto hereby waives, to the maximum extent not
prohibited by law, any right it may have to claim or recover in any legal action
or proceeding referred to in this subsection 10.12 any special, exemplary,
punitive or consequential damages.

                  10.13 Acknowledgements. The Borrower hereby acknowledges that:

                  (a) it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the other Loan Documents;

                  (b) neither the Administrative Agent nor any Lender has any
fiduciary relationship with or duty to the Borrower arising out of or in
connection with this Agreement or any of the other Loan Documents, and the
relationship between Administrative Agent and Lenders, on one hand, and the
Borrower, on the other hand, in connection herewith or therewith is solely that
of debtor and creditor; and

                  (c) no joint venture is created hereby or by the other Loan
Documents or otherwise exists by virtue of the transactions contemplated hereby
among the Lenders or among the Borrower and the Lenders.

                  10.14 Confidentiality. Each of the Agents and the Lenders
agrees to keep confidential all non-public information provided to it by any
Loan Party pursuant to this Agreement that is designated by such Loan Party as
confidential; provided that nothing herein shall prevent any Agent or any Lender
from disclosing any such information (a) to the Administrative Agent, any other
Lender or any affiliate of any Lender, (b) to any Participant or Assignee (each,
a "Transferee") or prospective Transferee which agrees to comply with the

                                       65
<PAGE>   71

provisions of this subsection 10.14, (c) any of its employees, directors,
agents, attorneys, accountants and other professional advisors, (d) upon the
request or demand of any Governmental Authority having jurisdiction over it, (e)
in response to any order of any court or other Governmental Authority or as may
otherwise be required pursuant to any Requirement of Law (exclusive of any
organizational or governance document of such Agent or Lender), (f) if requested
or required to do so in connection with any litigation or similar proceeding,
(g) which has been publicly disclosed other than in breach of this subsection
10.14, (h) to the National Association of Insurance Commissioners or any similar
organization or any nationally recognized rating agency that requires access to
information about a Lender's investment portfolio in connection with ratings
issued with respect to such Lender or (i) in connection with the exercise of any
remedy hereunder or under any other Loan Document. In the event that any Agent
or Lender shall have received a demand or request, or intends to respond to or
otherwise satisfy a requirement, for the delivery of any such confidential
information pursuant to the foregoing clause (f), such Agent or Lender promptly
shall make reasonable efforts to notify the Borrower thereof within any
applicable time period permitted to contest compliance with any such demand,
request or requirement; provided, that in no event shall any Lender or Agent be
liable for any action taken pursuant to such clause (f) or for any failure so to
notify the Borrower in accordance with the foregoing.

                  10.15 Enforceability; Usury. In no event shall any provision
of this Agreement, the Notes, or any other instrument evidencing or securing the
indebtedness of the Borrower hereunder ever obligate the Borrower to pay or
allow any Lender to collect interest on the Loans or any other indebtedness of
the Borrower hereunder at a rate greater than the maximum non-usurious rate
permitted by applicable law (herein referred to as the "Highest Lawful Rate"),
or obligate the Borrower to pay any taxes, assessments, charges, insurance
premiums or other amounts to the extent that such payments, when added to the
interest payable on the Loans, would be held to constitute the payment by the
Borrower of interest at a rate greater than the Highest Lawful Rate; and this
provision shall control over any provision to the contrary.

                  Without limiting the generality of the foregoing, in the event
the maturity of all or any part of the principal amount of the indebtedness of
the Borrower hereunder shall be accelerated for any reason, then such principal
amount so accelerated shall be credited with any interest theretofore paid
thereon in advance and remaining unearned at the time of such acceleration. If,
pursuant to the terms of this Agreement or the Notes, any funds are applied to
the payment of any part of the principal amount of the indebtedness of the
Borrower hereunder prior to the maturity thereof, then (a) any interest which
would otherwise thereafter accrue on the principal amount so paid by such
application shall be canceled, and (b) the indebtedness of the Borrower
hereunder remaining unpaid after such application shall be credited with the
amount of all interest, if any, theretofore collected on the principal amount so
paid by such application and remaining unearned at the date of said application;
and if the funds so applied shall be sufficient to pay in full all the
indebtedness of the Borrower hereunder, then the Lenders shall refund to the
Borrower all interest theretofore paid thereon in advance and remaining unearned
at the time of such acceleration. All sums paid or agreed to be paid to the
Administrative Agent or to any Lender for the use, forbearance or detention of
sums due hereunder shall, to the extent permitted by law applicable to the
Administrative Agent or such Lender, be amortized, prorated, allocated

                                       66
<PAGE>   72

and spread throughout the full term of the Loans until paid in full, so that the
rate or amount of interest on account of any Loans or other amounts hereunder
does not exceed the maximum amount allowed by such applicable law. Regardless of
any other provision in this Agreement, or in any of the written evidences of the
indebtedness of the Borrower hereunder, the Borrower shall never be required to
pay any unearned interest on such indebtedness or any portion thereof, and shall
never be required to pay interest thereon at a rate in excess of the Highest
Lawful Rate construed by courts having competent jurisdiction thereof.

                  10.16 Accounting Changes. In the event that any "Accounting
Change" (as defined below) shall occur and such change results in a change in
the method of calculation of financial covenants, standards or terms in this
Agreement, then the Borrower and the Administrative Agent agree to enter into
negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such Accounting Changes with the desired result that the
criteria for evaluating the Borrower's financial condition shall be the same
after such Accounting Changes as if such Accounting Changes had not been made.
Until such time as such an amendment shall have been executed and delivered by
the Borrower, the Administrative Agent and the Required Lenders, all financial
covenants, standards and terms in this Agreement shall continue to be calculated
or construed as if such Accounting Changes had not occurred. "Accounting
Changes" refers to changes in accounting principles required by the promulgation
of any rule, regulation, pronouncement or opinion by the Financial Accounting
Standards Board or the American Institute of Certified Public Accountants or, if
applicable, the Securities and Exchange Commission (or successors thereto or
agencies with similar functions).

                  10.17 WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS AND THE
LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND
FOR ANY COUNTERCLAIM THEREIN.

Changes in the Applicable Margin resulting from changes in the Consolidated
Leverage Ratio shall become effective on the date (the "Adjustment Date") on
which financial statements are delivered to the Lenders pursuant to subsection
6.1 (but in any event not later than the 60th day after the end of each of the
first three quarterly periods of each fiscal year or the 105th day after the end
of each fiscal year, as the case may be) and shall remain in effect until the
next change to be effected pursuant to this paragraph. If any financial
statements referred to above are not delivered within the time periods specified
above, then, until such financial statements are delivered, the Consolidated
Leverage Ratio as at the end of the fiscal period that would have been covered
thereby shall for the purposes of this definition be deemed to be greater than
3.25 : 1.0. In addition, at all times while an Event of Default shall have
occurred and be continuing, the Consolidated Leverage Ratio shall for the
purposes of this definition be deemed to be greater than 3.25 : 1.0. Each
determination of the Consolidated Leverage Ratio pursuant to this definition
shall be made with respect to the period of four consecutive fiscal

quarters of the Borrower and its consolidated Subsidiaries ending at the end of
the period covered by the relevant consolidated financial statements; provided
that the Consolidated EBITDA used to calculate the Consolidated Leverage Ratio
for the fiscal quarter ended September 30, 2000 be will equal 1.33 times the sum
of the Consolidated EBITDA for the three consecutive fiscal quarters ended on
such date.

The Pricing Grid set forth above under the caption "Pricing Grid II" will be
applicable only with respect to Adjustment Dates on which the Borrower has a
corporate credit rating or issuer rating from S&P or Moody's of at least BBB- or
Baa3, respectively.
