         2.01     AMOUNT AND TERMS OF COMMITMENTS.

         (a)      Subject to the terms and conditions set forth herein, each
Lender severally agrees to make, Convert and Continue loans (each such loan, a
"Loan") to Borrower in Dollars and Offshore Currencies in such amounts as
Borrower may from time to time request on any Business Day during the period
from the Closing Date to the Maturity Date, in an aggregate amount not to exceed
at any time outstanding the amount set forth on Schedule 2.01 (such amount as
the same may be reduced under Section 2.06 or as a result of one or more
assignments hereunder, such Lender's "Commitment"); provided, however, that,
after giving effect to any Borrowing, all Outstanding Obligations of each Lender
shall not exceed such Lender's Commitment and all Outstanding Obligations of all
Lenders shall not exceed the combined Commitments. This is a revolving credit

<PAGE>

and subject to the foregoing, and the other terms and conditions hereof,
Borrower may borrow, Convert, Continue, prepay and reborrow Loans as set forth
herein without premium or penalty.

         (b)      Loans made by each Lender shall be evidenced by one or more
Notes. Each such Lender may attach schedules to its Note(s) and endorse thereon
the date, amount, applicable currency and maturity of its Loans and payments
with respect thereto. Such Notes and records shall be conclusive absent manifest
error of the amount of such Loan and payments thereon . Any failure so to record
or any error in doing so shall not, however, limit or otherwise affect the
obligation of Borrower to pay any amount owing with respect to the Loans.

         (c)      Not used.

         (d)      Swing Line Commitment. Subject to the terms and conditions set
forth in this Agreement and so long as no Default or Event of Default has
occurred and is continuing (provided, however, that Bank of America, N.A. shall
have no liability to any other Lender for making a Swing Line Loan to Borrower
after the occurrence or during the continuance of any Default or Event of
Default unless Bank of America, N.A. has previously received notice in writing
from Borrower or any other Lender of the occurrence of such Default or Event of
Default), Bank of America, N.A. agrees to make such loans to Borrower
(individually, a "Swing Line Loan" and collectively, the "Swing Line Loans") as
Borrower may from time to time request pursuant to Section 2.02. Each Swing Line
Loan shall be for an aggregate principal amount of at least $100,000 or any
larger multiple of $10,000. The aggregate principal amount of Swing Line Loans
outstanding under this Agreement as of any date shall not exceed the amount of
the Swing Line Commitment; provided, however, that in no event shall all
Outstanding Obligations of all Lenders on any given day exceed the combined
Commitments. All Swing Line Loans shall be Base Rate Loans and all Swing Line
Loans together with all accrued and unpaid interest thereon and all fees and
other amounts owing by Borrowers to Bank of America with respect thereto, shall
be due and payable on the earlier of (i) the demand of Bank of America, N.A. and
(ii) seven (7) days after the date of the extension of the Swing Line Loan. The
Swing Line Loans of Bank of America, N.A. to a Borrower shall be evidenced by a
Swing Line Note of such Borrower payable to the order of Bank of America, N.A.
in a principal amount equal to the amount of the Swing Line Commitment, which
Swing Line Note shall be in substantially the form of Exhibit G attached hereto
and incorporated herein by reference (with appropriate insertions) (as the same
may from time to time be amended, modified extended, renewed or restated, the
"Swing Line Note"). The Swing Line Commitment and the making of Swing Line Loans
is a discretionary, uncommitted facility and Bank of America may terminate or
suspend the Swing Line Commitment at any time in its sole discretion upon notice
to Borrower, which notice may be given before or after Borrower requests a Swing
Line Loan.

         2.02     BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

         (a)      Borrower may irrevocably request a Borrowing, Conversion or
Continuation of Loans in a Minimum Amount therefor by delivering a Request for
Extension of Credit therefor by Requisite Notice to Administrative Agent not
later than the Requisite Time therefor. All Borrowings, Conversions and
Continuations shall constitute Base Rate Loans unless properly and timely
otherwise designated as set forth in the prior sentence. Loans may only be
Converted into or Continued as Loans denominated in the same currency as
originally borrowed.

<PAGE>

         (b)      Following receipt of a Request for Extension of Credit,
Administrative Agent shall promptly notify each Lender of its Pro Rata Share
thereof by Requisite Notice. If any Lender is unable in good faith to fund an
Offshore Currency Loan in a requested Offshore Currency, it shall promptly
notify Administrative Agent (who shall notify Company and the other Lenders),
and such Request for Extension of Credit shall be deemed withdrawn.
Administrative Agent shall promptly upon Borrower's request notify the
applicable Borrower and Lenders of the interest rate applicable to any Loans
proposed by Borrower upon determination of same. In the case of a Borrowing of
Loans, each Lender shall make the funds for its Loan available in the currency
of such Loan to Administrative Agent at Administrative Agent's Office not later
than the Requisite Time therefor on the Business Day specified in such Request
for Extension of Credit. Upon satisfaction of the applicable conditions set
forth in Section 4.02, (and if the initial Extension of Credit hereunder,
Section 4.01), all funds so received shall be made available to the Borrower in
like funds received.

         (c)      Administrative Agent shall promptly notify Company and Lenders
of the interest rate applicable to any Loan other than a Base Rate Loan upon
determination of same in accordance with this Agreement.

         (d)      Except as otherwise provided herein, an Offshore Rate Loan may
be Continued or Converted only on the last day of the Interest Period for such
Offshore Rate Loan. During the existence of a Default or Event of Default, no
Loans may be requested as, Converted into or Continued as Offshore Rate Loans
without the consent of Requisite Lenders and Requisite Lenders may demand that
any or all of the then outstanding Offshore Rate Loans be Converted immediately
into Base Rate Loans.

         (e)      If a Loan is to be made to Borrower on the same date that
another Loan in the same currency is due and payable by Borrower, Borrower or
Lenders, as the case may be, shall, upon the request of Administrative Agent,
make available to Administrative Agent the net amount of funds giving effect to
both such Loans and the effect for purposes of this Agreement shall be the same
as if separate transfers of funds had been made with respect to each such Loan.
In the absence of such a request, separate transfers of funds shall be made with
respect to each such Loan.

         (f)      Borrower may from time to time request Extensions of Credit
(other than for Swing Line Loans, all of which shall be made in Dollars) in
currencies other than those listed in the definition of Offshore Currency so
long as such currency is freely traded in the offshore interbank foreign
exchange markets and freely transferable and freely convertible into Dollars.
Borrower shall request any such additional currency by Requisite Notice to
Administrative Agent (who shall promptly notify each Lender) not later than the
Requisite Time therefor. Each Lender shall notify Administrative Agent (who
shall promptly notify Company) whether it will, in its sole discretion, make an
Extension of Credit in such requested currency. If all Lenders consent to such
currency, such currency shall thereafter be deemed for all purposes an Offshore
Currency hereunder available for Extensions of Credit.

         (g)      Without prejudice and in addition to any method of conversion
or rounding prescribed by any EMU Legislation and without prejudice to (i) the
liabilities for indebtedness of each Borrower Party to Lenders under or pursuant
to this Agreement or (ii) Lenders' Commitments, any reference in this Agreement
to a minimum amount (or an integral multiple thereof) in a national currency of
a Subsequent Participant to be paid to or by Administrative Agent shall
immediately, upon it becoming a Subsequent Participant, be replaced by a
reference to such reasonably

<PAGE>

comparable and convenient amount (or an integral multiple thereof) in the euro
unit as Administrative Agent may specify in good faith.

         2.03     LETTERS OF CREDIT.

         (a)      THE LETTER OF CREDIT COMMITMENT. Subject to the terms and
conditions set forth in this Agreement, until the Maturity Date, Issuing Lender
shall take such Letter of Credit Actions denominated in Dollars or Offshore
Currencies as Borrower may from time to time request; provided, however, that
(i) the Equivalent Amount in Dollars of the Outstanding Obligations of each
Lender shall not exceed such Lender's Commitment, (ii) the Equivalent Amount in
Dollars of the Outstanding Obligations of all Lenders shall not exceed the
combined Commitments at any time, and (iii) all Letter of Credit Usage shall not
exceed the Letter of Credit Sublimit at any time. Subject to subsection (f)
below and, unless consented to by Issuing Lender and Requisite Lenders, no
Letter of Credit (other than Letter of Credit #705264 in the face amount of
$25,000 in favor of City of Chicago, Department of Transportation) may expire
more than 12 months after the date of its issuance or last renewal; provided,
however, that no Letter of Credit shall expire more than 12 months after the
Maturity Date. If any Letter of Credit Usage remains outstanding after the
Maturity Date, Borrower shall, not later than such date, deposit cash in an
amount equal to such Letter of Credit Usage in a Letter of Credit Cash
Collateral Account. Letters of Credit issued and outstanding under the Existing
Credit Facility on the Closing Date shall be deemed validly issued and
outstanding Letters of Credit with the same terms and maturity under this
Agreement as under the Existing Credit Facility.

         (b)      REQUESTING LETTER OF CREDIT ACTIONS. Borrower may irrevocably
request a Letter of Credit Action in a Minimum Amount therefor by delivering a
Letter of Credit Application therefor to Issuing Lender, with a copy to
Administrative Agent (who shall notify Lenders), by Requisite Notice not later
than the Requisite Time therefor. Each Letter of Credit Action shall be in a
form acceptable to Issuing Lender in its reasonable discretion. Unless
Administrative Agent notifies Issuing Lender that such Letter of Credit Action
is not permitted hereunder, or Issuing Lender notifies Administrative Agent that
it has determined in good faith that such Letter of Credit Action is contrary to
any Laws or policies of Issuing Lender, Issuing Lender shall, upon satisfaction
of the applicable conditions set forth in Section 4.02 with respect to any
Letter of Credit Action constituting an Extension of Credit, effect such Letter
of Credit Action. This Agreement shall control in the event of any conflict with
any Letter of Credit Application, including without limitation, any definition
of "Default" or "Event of Default" in any such Letter of Credit Application,
which shall be deemed superseded by the definitions thereof in this Agreement.
Any requirement therein or in any provision of this Agreement to grant a
security interest shall be subject to the prohibitions contained in Section 7.03
hereof and in Section 10.5 of the Note Purchase Agreement-1997 and to any
equivalent provision in the Note Purchase Agreement-2003. Upon the issuance of a
Letter of Credit, each Lender shall be deemed to have purchased from Issuing
Lender a risk participation therein in an amount equal to such Lender's Pro Rata
Share times the amount of such Letter of Credit.

         (c)      REIMBURSEMENT OF PAYMENTS UNDER LETTERS OF CREDIT. Borrower
shall reimburse Issuing Lender through Administrative Agent for any payment that
Issuing Lender makes under a Letter of Credit on or before the date of such
payment; provided, however, that if the conditions precedent set forth in
Section 4.02 can be satisfied, Borrower may request a Borrowing of Loans to
reimburse Issuing Lender for such payment pursuant to Section 2.02, or, failing
to make such

<PAGE>

request, Borrower shall be deemed to have requested a Borrowing of Base Rate
Loans on such payment date pursuant to subsection (e) below.

         (d)      FUNDING BY LENDERS WHEN ISSUING LENDER NOT REIMBURSED. Upon
any drawing under a Letter of Credit, Issuing Lender shall notify Administrative
Agent and Company. If Borrower fails to timely make the payment required
pursuant to subsection (c) above, Issuing Lender shall notify Administrative
Agent of such fact and the amount of such unreimbursed payment. Administrative
Agent shall promptly notify each Lender of its Pro Rata Share of such amount by
Requisite Notice. Each Lender shall make funds in an amount equal its Pro Rata
Share of such amount available to Administrative Agent at Administrative Agent's
Office not later than the Requisite Time therefor on the Business Day specified
by Administrative Agent, and Administrative Agent shall remit the funds so
received to Issuing Lender. The obligation of each Lender to so reimburse
Issuing Lender shall be absolute and unconditional and shall not be affected by
the occurrence of a Default or Event of Default or any other occurrence or
event. Any such reimbursement shall not relieve or otherwise impair the
obligation of Borrower to reimburse Issuing Lender for the amount of any payment
not made by Borrower under any Letter of Credit, together with interest as
provided herein.

         (e)      NATURE OF LENDERS' FUNDING. If the conditions precedent set
forth in Section 4.02 can be satisfied (except for the giving of a Request for
Extension of Credit) on any date Borrower is obligated to, but fails to,
reimburse Issuing Lender for a drawing under a Letter of Credit, the funding by
Lenders pursuant to the previous subsection shall be deemed to be a Borrowing of
Base Rate Loans (without regard to the Minimum Amount therefor) deemed requested
by Borrower. If the conditions precedent set forth in Section 4.02 cannot be
satisfied on the date Borrower is obligated to, but fails to, reimburse Issuing
Lender for a drawing under a Letter of Credit, the funding by Lenders pursuant
to the previous subsection shall be deemed to be a funding by each Lender of its
risk participation in such Letter of Credit, and each Lender making such funding
shall thereupon acquire a pro rata participation, to the extent of its
reimbursement, in the claim of Issuing Lender against Borrower in respect of
such payment and shall share, in accordance with that pro rata participation, in
any payment made by Borrower with respect to such claim. Any amounts made
available by a Lender under its risk participation shall be payable by Borrower
upon demand of Administrative Agent, and shall bear interest at a rate per annum
equal to the Default Rate.

         (f)      SPECIAL PROVISIONS RELATING TO EVERGREEN LETTERS OF CREDIT.
Borrower may request Letters of Credit that have automatic extension or renewal
provisions ("evergreen" Letters of Credit) so long as Issuing Lender consents in
its sole and absolute discretion thereto and has the right to not permit any
such extension or renewal at least annually within a notice period to be agreed
upon at the time each such Letter of Credit is issued. Once an evergreen Letter
of Credit is issued, unless Administrative Agent has notified Issuing Lender
that Requisite Lenders have elected not to permit such extension or renewal, the
Borrower Parties, Administrative Agent and Lenders shall be deemed to have
authorized (but may not require) Issuing Lender to, in its sole and absolute
discretion, permit the renewal of such evergreen Letter of Credit at any time to
a date not later than the Maturity Date, and, unless directed by Issuing Lender,
Borrower shall not be required to request such extension or renewal. Issuing
Lender may, in its sole and absolute discretion, elect not to permit an
evergreen Letter of Credit to be extended or renewed at any time.

         (g)      OBLIGATIONS ABSOLUTE. The obligation of Borrower to pay to
Issuing Lender the amount of any payment made by Issuing Lender under any Letter
of Credit issued for its account

<PAGE>

shall be absolute, unconditional, and irrevocable. Without limiting the
foregoing, Borrower's obligation shall not be affected by any of the following
circumstances:

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

                  (ii)     any amendment or waiver of or any consent to
         departure from such Letter of Credit, this Agreement, or any other
         agreement or instrument relating hereto or thereto;

                  (iii)    the existence of any claim, setoff, defense, or other
         rights which Borrower may have at any time against Issuing Lender,
         Administrative Agent or any Lender, any beneficiary of such Letter of
         Credit (or any persons or entities for whom any such beneficiary may be
         acting) or any other Person, whether in connection with such Letter of
         Credit, this Agreement, or any other agreement or instrument relating
         thereto, or any unrelated transactions;

                  (iv)     any demand, statement, or any other document
         presented under such Letter of Credit proving to be forged, fraudulent,
         invalid, or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect whatsoever so long as any such
         document appeared to comply with the terms of the Letter of Credit;

                  (v)      payment by Issuing Lender in good faith under such
         Letter of Credit against presentation of a draft or any accompanying
         document which does not strictly comply with the terms of such Letter
         of Credit; or any payment made by Issuing Lender under such Letter of
         Credit to any Person purporting to be a trustee in bankruptcy,
         debtor-in-possession, assignee for the benefit of creditors,
         liquidator, receiver or other representative of or successor to any
         beneficiary or any transferee of such Letter of Credit, including any
         arising in connection with any proceeding under any Debtor Relief Laws;

                  (vi)     the existence, character, quality, quantity,
         condition, packing, value or delivery of any property purported to be
         represented by documents presented in connection with such Letter of
         Credit or for any difference between any such property and the
         character, quality, quantity, condition, or value of such property as
         described in such documents;

                  (vii)    the time, place, manner, order or contents of
         shipments or deliveries of property as described in documents presented
         in connection with such Letter of Credit or the existence, nature and
         extent of any insurance relative thereto;

                  (viii)   the solvency or financial responsibility of any party
         issuing any documents in connection with such Letter of Credit;

                  (ix)     any failure or delay in notice of shipments or
         arrival of any property;

                  (x)      any error in the transmission of any message relating
         to such Letter of Credit not caused by Issuing Lender, or any delay or
         interruption in any such message;

                  (xi)     any error, neglect or default of any correspondent of
         Issuing Lender in connection with such Letter of Credit;

<PAGE>

                  (xii)    any consequence arising from acts of God, wars,
         insurrections, civil unrest, disturbances, labor disputes, emergency
         conditions or other causes beyond the control of Issuing Lender;

                  (xiii)   so long as Issuing Lender in good faith determines
         that the document appears to comply with the terms of the Letter of
         Credit, the form, accuracy, genuineness or legal effect of any contract
         or document referred to in any document submitted to Issuing Lender in
         connection with such Letter of Credit; and

                  (xiv)    any other circumstances whatsoever where Issuing
         Lender has acted in good faith.

         In addition, Borrower will promptly examine a copy of each Letter of
Credit and amendments thereto delivered to it and, in the event of any claim of
noncompliance with Borrower's instructions or other irregularity, Borrower will
immediately notify Issuing Lender in writing. Borrower shall be conclusively
deemed to have waived any such claim against Issuing Lender and its
correspondents unless such notice is given as aforesaid.

         (h)      ROLE OF ISSUING LENDER. Each Lender and Borrower agree that,
in paying any drawing under a Letter of Credit, Issuing Lender shall not have
any responsibility to obtain any document (other than any sight draft,
certificates and documents expressly required by the Letter of Credit) or to
ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. No
Administrative Agent-Related Person nor any of the respective correspondents,
participants or assignees of Issuing Lender shall be liable to any Lender for
any action taken or omitted in connection herewith at the request or with the
approval of Lenders or Requisite Lenders, as applicable; any action taken or
omitted in the absence of gross negligence or willful misconduct; or the due
execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit. Borrower hereby assumes all risks of
the acts or omissions of any beneficiary or transferee with respect to its use
of any Letter of Credit. No Administrative Agent-Related Person, nor any of the
respective correspondents, participants or assignees of Issuing Lender, shall be
liable or responsible for any of the matters described in subsection (g) above.
In furtherance and not in limitation of the foregoing, Issuing Lender may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary,
and Issuing Lender shall not be responsible for the validity or sufficiency of
any instrument transferring or assigning or purporting to transfer or assign a
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.

         (i)      APPLICABILITY OF ISP98 AND UCP. Unless otherwise expressly
agreed by Issuing Lender and Borrower when a Letter of Credit is issued and
subject to applicable laws, performance under Letters of Credit by Issuing
Lender, its correspondents, and beneficiaries will be governed by (i) with
respect to standby Letters of Credit, the rules of the "International Standby
Practices 1998" ("ISP98") or such later revision as may be published by the
Institute of International Banking Law & Practice, subject to applicable laws,
and (ii) with respect to commercial Letters of Credit, the rules of the Uniform
Customs and Practice for Documentary Credits, as published in its most recent
version by the International Chamber of Commerce (the "ICC") on the date any
commercial Letter of Credit is issued, and including the ICC decision published
by the Commission on Banking Technique and Practice on April 6, 1998 regarding
the European single currency (euro).

<PAGE>

         (j)      LETTER OF CREDIT FEE. With respect to each Letter of Credit,
Company shall pay to Administrative Agent for the account of Issuing Lender an
upfront fee equal to such amount as is required by Issuing Lender pursuant to
the Fee Letter. With respect to standby Letters of Credit, Company shall pay to
Administrative Agent on each March 31, June 30, September 30 and December 31, in
arrears, for the account of each Lender in accordance with its Pro Rata Share, a
Letter of Credit fee equal to the Applicable Amount for such Letter of Credit
times the actual daily maximum amount available to be drawn under each Letter of
Credit since the later of the Closing Date and the previous Applicable Payment
Date. If there is any change in the Applicable Amount during any quarter, the
actual daily amount shall be computed and multiplied by the Applicable Amount
separately for each period during such quarter that such Applicable Amount was
in effect.

         (k)      DOCUMENTARY AND PROCESSING CHARGES PAYABLE TO ISSUING LENDER.
Company shall pay directly to Issuing Lender, upon demand, for its sole account
its customary documentary and processing charges in accordance with its standard
schedule, as from time to time in effect, for any Letter of Credit Action or
other occurrence relating to a Letter of Credit for which such charges are
customarily made.

         2.04     PREPAYMENTS. Upon Requisite Notice to Administrative Agent not
later than the Requisite Time therefor, Borrower may at any time and from time
to time voluntarily prepay Loans in part in the Minimum Amount therefor or in
full without premium or penalty. Administrative Agent will promptly notify each
Lender thereof and of such Lender's Pro Rata Share of such prepayment. Borrower
may, upon notice to Bank of America, specifying that Borrower is paying the
Swing Line Loans, prepay without penalty or premium the Swing Line Loans in
whole at any time or in part from time to time, by paying the principal amount
and all interest due and payable to be paid. If for any reason the Outstanding
Obligations exceed the combined Commitments as in effect or as reduced or
because of any limitation set forth in this Agreement or otherwise, Borrower
shall immediately prepay its Loans in an amount sufficient to eliminate such
excess. Any prepayment of an Offshore Rate Loan shall be accompanied by all
accrued interest thereon, together with the costs set forth in Section 3.05.

         2.05     NOT USED.

         2.06     REDUCTION OR TERMINATION OF COMMITMENTS. Upon Requisite Notice
to Administrative Agent not later than the Requisite Time therefor, Company may
at any time and from time to time, without premium or penalty, permanently and
irrevocably reduce the Commitments in a Minimum Amount therefor to an amount not
less than the Outstanding Obligations at such time or terminate the Commitments.
Any such reduction or termination shall be accompanied by payment of all accrued
and unpaid commitment fees with respect to the portion of the Commitments being
reduced or terminated. Administrative Agent shall promptly notify Lenders of any
such request for reduction or termination of the Commitments. Each Lender's
Commitment shall be reduced by an amount equal to such Lender's Pro Rata Share
times the amount of such reduction.

         2.07     PRINCIPAL AND INTEREST.

         (a)      Except as otherwise provided hereunder, if not sooner paid,
Borrower agrees to pay the outstanding principal amount of each Loan on the
Maturity Date.

<PAGE>

         (b)      Subject to subsection (c) below, and unless otherwise
specified herein, Borrower shall pay interest on the unpaid principal amount of
each Loan (before and after default, before and after maturity, before and after
judgment, and before and after the commencement of any proceeding under any
Debtor Relief Laws) from the date borrowed until paid in full (whether by
acceleration or otherwise) on each Applicable Payment Date at a rate per annum
equal to the interest rate determined in accordance with the definition of such
type of Loan, plus, to the extent applicable in each case, the Applicable Amount
for such type of Loan. Administrative Agent shall invoice Company for the amount
of interest due on any Base Rate Loan on the due date thereof.

         (c)      If any amount payable by any Borrower Party under any Loan
Document is not paid when due (without regard to any applicable grace periods),
it shall thereafter bear interest (after as well as before entry of judgment
thereon to the extent permitted by law) at a fluctuating interest rate per annum
at all times equal to the Default Rate to the fullest extent permitted by
applicable Law. Accrued and unpaid interest on past due amounts (including
interest on past due interest) shall be payable upon demand.

         (d)      So long as no Event of Default has occurred and is continuing,
each Swing Line Loan shall bear interest on the outstanding principal amount
thereof, for each day from the date such Swing Line Loan is made until it
becomes due, at a rate per annum equal to the Base Rate. So long as any Event of
Default has occurred and is continuing, each Swing Line Loan shall bear interest
on the outstanding principal amount thereof, for each day from the date such
Swing Line Loan is made until it becomes due, at a rate per annum equal to Two
Percent (2%) over and above the Base Rate. Such interest shall be payable when
the Swing Loan Note is paid or matures. From and after its due date, whether by
reason of acceleration upon demand or otherwise, each Swing Line Loan shall bear
interest, payable on demand, for each day until paid at a rate per annum equal
to Two Percent (2%) over and above the Base Rate.

         2.08     FEES.

         (a)      COMMITMENT FEE. Company shall pay to Administrative Agent for
the account of each Lender pro rata according to its Pro Rata Share, a
Commitment fee equal to the Applicable Amount times the actual daily amount by
which the combined Commitments exceed the Outstanding Obligations (excluding the
outstanding balances of Swing Line Loans). The commitment fee shall accrue at
all times from the Closing Date until the Maturity Date and shall be payable
quarterly in arrears on each March 31, June 30, September 30 and December 31.
The commitment fee shall be calculated quarterly in arrears, and if there is any
change in the Applicable Amount during any quarter, the actual daily amount
shall be computed and multiplied by the Applicable Amount separately for each
period during such quarter that such Applicable Amount was in effect. The
commitment fee shall accrue at all times, including at any time during which one
or more conditions in Section 4 are not met.

         (b)      AGENCY FEES. An agency fee for the services to be performed by
Administrative Agent hereunder shall be payable to Administrative Agent in the
amount and at such times as are specified in the Fee Letter.

         (c)      OTHER FEES. Company shall pay any additional fees from time to
time agreed upon by each Lender and Company which are set forth in the Fee
Letter.

<PAGE>

         2.09     COMPUTATION OF INTEREST AND FEES. Computation of interest on
Base Rate Loans when the Base Rate is determined by Bank of America's "prime
rate" shall be calculated on the basis of a year of 365 or 366 days, as the case
may be, and the actual number of days elapsed. Computation of all other types of
interest and all fees shall be calculated on the basis of a year of 360 days and
the actual number of days elapsed, which results in a higher yield to Lenders
than a method based on a year of 365 or 366 days. Interest shall accrue on each
Loan for the day on which the Loan is made, and shall not accrue on a Loan, or
any portion thereof, for the day on which the Loan or such portion is paid,
provided that any Loan that is repaid on the same day on which it is made shall
bear interest for one day.

         2.10     MAKING PAYMENTS.

         (a)      Except as otherwise provided herein, all payments by Borrower
or any Lender hereunder shall be made to Administrative Agent at Administrative
Agent's Office not later than the Requisite Time for such type of payment. All
payments received after such Requisite Time shall be deemed received on the next
succeeding Business Day. All payments shall be made in immediately available
funds in the currency of such extension of credit (or, with the consent of
Administrative Agent in each instance, the Equivalent Amount in Dollars of the
Applicable Offshore Currency). All payments by Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.

         (b)      Upon satisfaction of any applicable terms and conditions set
forth herein, Administrative Agent shall promptly make any amounts received in
accordance with the prior subsection available in like funds received as
follows: (i) if payable to Borrower, by crediting the Designated Deposit
Account, and (ii) if payable to any Lender, by wire transfer to such Lender at
its Lending Office. If such conditions are not so satisfied, Administrative
Agent shall return any funds it is holding to the Lenders making such funds
available, without interest.

         (c)      Subject to the definition of "Interest Period," if any payment
to be made by any Borrower Party shall come due on a day other than a Business
Day, payment shall instead be considered due on the next succeeding Business
Day, and such extension of time shall be reflected in computing interest and
fees.

         (d)      Unless Company or any Lender has notified Administrative Agent
prior to the date any payment to be made by it is due, that it does not intend
to remit such payment, Administrative Agent may, in its sole and absolute
discretion, assume that Borrower or such Lender, as the case may be, has timely
remitted such payment and may, in its sole and absolute discretion and in
reliance thereon, make available such payment to the Person entitled thereto. If
such payment was not in fact remitted to Administrative Agent in immediately
available funds, then:

                  (i)      if Borrower failed to make such payment, each Lender
         shall forthwith on demand repay to Administrative Agent the amount of
         such assumed payment made available to such Lender, together with
         interest thereon in respect of each day from and including the date
         such amount was made available by Administrative Agent to such Lender
         to the date such amount is repaid to Administrative Agent at the
         Overnight Rate; and

                  (ii)     if any Lender failed to make such payment,
         Administrative Agent shall be entitled to recover such corresponding
         amount on demand from such Lender . If such

<PAGE>

         Lender does not pay such corresponding amount forthwith upon
         Administrative Agent's demand therefor, Administrative Agent promptly
         shall notify Borrower, and Borrower shall pay such corresponding amount
         to Administrative Agent. Administrative Agent also shall be entitled to
         recover from such Lender interest on such corresponding amount in
         respect of each day from the date such corresponding amount was made
         available by Administrative Agent to Borrower to the date such
         corresponding amount is recovered by Administrative Agent, (A) from
         such Lender at a rate per annum equal to the daily Overnight Rate, and
         (B) from Borrower, at a rate per annum equal to the interest rate
         applicable to such Borrowing. Nothing herein shall be deemed to relieve
         any Lender from its obligation to fulfill its Commitment or to
         prejudice any rights which Administrative Agent or Borrower may have
         against any Lender as a result of any default by such Lender hereunder.

         (e)      If Administrative Agent or any Lender is required at any time
to return to Borrower, or to a trustee, receiver, liquidator, custodian, or any
official under any proceeding under Debtor Relief Laws, any portion of a payment
made by Borrower, each Lender shall, on demand of Administrative Agent, return
its share of the amount to be returned, plus interest thereon from the date of
such demand to the date such payment is made at a rate per annum equal to the
daily Federal Funds Rate.

         2.11     FUNDING SOURCES. Nothing in this Agreement shall be deemed to
obligate any Lender to obtain the funds for any Loan in any particular place or
manner or to constitute a representation by any Lender that it has obtained or
will obtain the funds for any Loan in any particular place or manner.

         2.12     SWING LINE LOAN SETTLEMENT AFTER DEFAULT. Upon the occurrence
of any Event of Default or the demand for payment under the Swing Line Loans by
Bank of America, N.A., unless otherwise requested by Bank of America, N.A., the
Administrative Agent shall promptly notify the other Lenders in writing of the
aggregate principal amount of all Swing Line Loans from Bank of America, N.A.
then outstanding, and each of the other Lenders hereby irrevocably agrees to
immediately purchase from Bank of America, N.A. with immediately available funds
its ratable share of the amount of all such Swing Line Loans (based on such
Lender's pro rata share of the combined Commitments), plus accrued and unpaid
interest calculated on such pro rata share of such principal amount at a rate
per annum equal to the Base Rate. Following such advance by each Lender to Bank
of America, N.A. of its pro rata share of any such Swing Line Loans pursuant to
the preceding sentence, each such Lender shall thereafter receive its pro rata
share of all principal payments, interest payments, fees and other amounts due
with respect to such Swing Line Loans as and when paid by Borrower to Bank of
America, N.A. hereunder. Bank of America, N.A. agrees that it will not make any
Swing Line Loan to Borrower after Bank of America, N.A. has received notice in
writing from Borrower or any other Lender that a Default or Event of Default has
occurred and is continuing, without the prior written consent of the Requisite
Banks.

                                   SECTION 3.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01     TAXES.

         (a)      Any and all payments by Borrower to or for the account of
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of
Administrative Agent and each Lender, taxes imposed on or measured by its net
income or branch profits or franchise taxes imposed on it (in lieu of net income
or branch profits taxes), by the United States of America or by the jurisdiction
(or any political subdivision thereof) under the Laws of which Administrative
Agent or such Lender, as the case may be, is organized, in which its principal
office is located or in which it maintains a lending office, and any other taxes
withheld because such Lender failed to timely deliver the forms required
pursuant to Section 10.21 (all such non-excluded taxes, duties, levies, imposts,
deductions, assessments, fees, withholdings or similar charges, and liabilities
being hereinafter referred to as "Taxes"). If Borrower shall be required by any
Laws to deduct any Taxes from or in respect of any sum payable under any Loan
Document to Administrative Agent or any Lender, (i) the sum payable shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section),
Administrative Agent and such Lender receives an amount equal to the sum it
would have received had no such deductions been made, (ii) Borrower shall make
such deductions, (iii) Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
Laws, and (iv) within 30 days after the date of such payment, Borrower shall
furnish Administrative Agent (who shall forward the same to such Lender) the
original or a certified copy of a receipt evidencing payment thereof.

         (b)      In addition, Borrower agrees to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes").

         (c)      If Borrower shall be required by the Laws of any jurisdiction
outside the United States to deduct any Taxes from or in respect of any sum
payable under any Loan Document to Administrative Agent or any Lender, Borrower
shall also pay to such Lender or Administrative Agent (for the account of such
Lender), at the time interest is paid, such additional amount that the
respective Lender specifies as necessary to preserve the after-tax yield (after
factoring in United States (federal and state) taxes imposed on or measured by
net income) such Lender would have received if such deductions (including
deductions applicable to additional sums payable under this Section) had not
been made.

         (d)      Borrower agrees to indemnify Administrative Agent and each
Lender for the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by Administrative Agent and such Lender and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.

<PAGE>

         3.02     ILLEGALITY. If the introduction of any Laws or any change in
any Laws or in the interpretation or administration thereof has made it
unlawful, or any central bank or other Governmental Authority has asserted that
it is unlawful, for any Lender or its applicable Lending Office to make,
maintain or fund Offshore Rate Loans, or materially restricts the authority of
such Lender to purchase or sell, or to take deposits of, Dollars or the
applicable Offshore Currency in the applicable offshore interbank market, or to
determine or charge interest rates based upon the Offshore Rate, then, on notice
thereof by such Lender to Company through Administrative Agent, any obligation
of such Lender to make Offshore Rate Loans shall be suspended until the
circumstances giving rise to such determination no longer exist. Upon receipt of
such notice, Borrower shall, upon demand from such Lender (with a copy to
Administrative Agent), prepay or Convert all Offshore Rate Loans of such Lender,
either on the last day of the Interest Period thereof, if such Lender may
lawfully continue to maintain such Offshore Rate Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such Offshore
Rate Loans. Each Lender agrees to designate a different Lending Office if such
designation will avoid the need for such notice and will not, in the good faith
judgment of such Lender, otherwise be materially disadvantageous to such Lender.

         3.03     INABILITY TO DETERMINE OFFSHORE RATES. If, in connection with
any Request for Extension of Credit involving any Offshore Rate Loan, (a)
deposits in Dollars or the applicable Offshore Currency are not being offered to
banks in the applicable offshore market in the amount and for the Interest
Period of the requested Offshore Rate Loan, (b) adequate and reasonable means do
not exist for determining the underlying interest rate for such Offshore Rate
Loan, or (c) such underlying interest rate does not adequately and fairly
reflect the cost to Lenders of funding such Offshore Rate Loan, Administrative
Agent will promptly notify Company and all Lenders. Thereafter, the obligation
of Lenders to make or maintain such Offshore Rate Loan shall be suspended until
such circumstances have ceased to exist, whereupon Administrative Agent shall
revoke such notice. Upon receipt of such notice, Borrower may revoke any pending
request for a Borrowing of Offshore Rate Loans or, failing that, be deemed to
have converted such request into a request for a Borrowing of Base Rate Loans in
the amount specified therein.

         3.04     INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY.

         (a)      If, due to either the introduction of or any change in or in
the interpretation of any Law or the compliance with any guideline or request of
general applicability from any central bank or other Governmental Authority
(whether or not having the force of law):

                  (i)      subjects any Lender to any Tax, duty, or other charge
         with respect to any Offshore Rate Loans or its obligation to make
         Offshore Rate Loans, or change the basis on which taxes are imposed on
         any amounts payable to such Lender under this Agreement in respect of
         any Offshore Rate Loans;

                  (ii)     shall impose or modify any reserve, special deposit,
         or similar requirement (other than the reserve requirement utilized in
         the determination of the Offshore Rate) relating to Offshore Rate Loans
         or other assets of, or any deposits with or other liabilities or
         commitments of, any Lender (including its Commitment) with respect
         thereto; or

<PAGE>

                  (iii)    shall impose on any Lender or on the offshore Dollar
         interbank market any other condition affecting Offshore Rate Loans
         under this Agreement or any of such extensions of credit or liabilities
         or commitments;

and the result of any of the foregoing is to increase the cost to such Lender of
making, Converting into, Continuing, or maintaining any Offshore Rate Loans or
to reduce any sum received or receivable by such Lender under this Agreement
with respect to any Offshore Rate Loans, then from time to time upon demand of
Lender (with a copy of such demand to Administrative Agent), Borrower shall pay
to such Lender such additional amounts as will compensate such Lender for such
increased cost or reduction.

         (b)      If any change in or the interpretation of any Laws have the
effect of reducing the rate of return on the capital of any Lender or compliance
by any Lender (or its Lending Office) or any corporation controlling any Lender
as a consequence of any Lender's obligation hereunder (taking into consideration
its policies with respect to capital adequacy and such Lender's desired return
on capital), then from time to time upon demand of such Lender (with a copy to
Administrative Agent), Borrower shall pay to such Lender such additional amounts
as will compensate such Lender for such reduction.

         3.05     BREAKFUNDING COSTS. Upon demand of any Lender (with a copy to
Administrative Agent) from time to time, Borrower shall promptly compensate such
Lender for and hold such Lender harmless from any loss, cost or expense incurred
by it as a result of:

         (a)      any Continuation, Conversion, payment or prepayment of any
Loan other than a Base Rate Loan on a day other than the last day of the
Interest Period for such Loan (whether voluntary, mandatory, automatic, by
reason of acceleration, or otherwise); or

         (b)      any failure by Borrower (for a reason other than the failure
of such Lender to make a Loan) to prepay, borrow, Continue or Convert any Loan
other than a Base Rate Loan on the date or in the amount notified by Borrower;

including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
Borrower shall also pay any customary administrative fees charged by such Lender
in connection with the foregoing.

         3.06     MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

under this Section 3 shall in each case furnish a certificate to Company that
states in reasonable detail in good faith the additional amount or amounts to be
paid to it hereunder and the basis therefor. Any such certificate shall be
conclusive in the absence of clearly demonstrable error. In determining such
amount, Administrative Agent or any Lender may use any reasonable averaging and
attribution methods. For purposes of this Section 3, a Lender shall be deemed to
have funded each Offshore Rate Loan at the Offshore Base Rate used in
determining the Offshore Rate for such Loan by a matching deposit or other
borrowing in the offshore Dollar interbank market, whether or not such Offshore
Rate Loan was in fact so funded.

                                   SECTION 5.
                         REPRESENTATIONS AND WARRANTIES

         Each Borrower severally represents and warrants to Administrative Agent
and Lenders that:

         5.01     ORGANIZATION AND EXISTENCE. Each Covered Person is duly
organized and existing in good standing under the laws of the jurisdiction of
its organization, is duly qualified to do business and is in good standing in
every jurisdiction where the nature or extent of its business or properties
require it to be qualified to do business, except where the failure to so
qualify will not have a Material Adverse Effect. Each Covered Person has the
power and authority to own its properties and carry on its business as now being
conducted.

         5.02     AUTHORIZATION. Each Borrower Party is duly authorized to
execute and perform every Loan Document to which such Borrower Party is a party,
and each Borrower is duly authorized to borrow hereunder, and the Loan Documents
to which it is a party have been duly authorized by all requisite corporate (or,
if not a corporation, comparable) action of Borrower Party. No consent, approval
or authorization of, or declaration or filing with, any Governmental Authority,
and no consent of any other Person, is required in connection with any Borrower
Party's execution, delivery or performance of this Agreement and the other Loan
Documents, except for those already duly obtained or explicitly contemplated
hereunder.

         5.03     DUE EXECUTION. Every Loan Document to which a Borrower Party
is a party has been executed on behalf of such Borrower Party by a legally
competent Person duly authorized to do so.

         5.04     ENFORCEABILITY OF OBLIGATIONS. Each of the Loan Documents to
which a Borrower Party is a party constitutes the legal, valid and binding
obligation of such Borrower Party, enforceable against such Borrower Party in
accordance with its terms, except to the extent that the enforceability thereof
against such Borrower Party may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights generally
or by equitable principles of general application.

         5.05     BURDENSOME OBLIGATIONS. No Covered Person is a party to or
bound by any Contract or is subject to any provision in the Charter Documents of
such Covered Person which would, if performed by such Covered Person, result in
a Default or Event of Default either immediately or upon the elapsing of time.

         5.06     LEGAL RESTRAINTS. The execution of any Loan Document by a
Borrower Party will not violate or constitute a default under the Charter
Documents of such Borrower Party, any Material Agreement of such Borrower Party,
or any Material Law, and will not, except as expressly contemplated or permitted
in this Agreement, result in any Security Interest being imposed on any of such
Borrower Party's property. The performance by any Borrower Party of its
obligations under any Loan Document to which it is a party will not violate or
constitute a default under the Charter Documents of such Borrower Party, any
Material Agreement of such Borrower Party, or any Material Law, and will not,
except as expressly contemplated or permitted in this Agreement, result in any
Security Interest being imposed on any of such Borrower Party's property.

         5.07     LABOR DISPUTES. There is no pending or, to Company's
knowledge, threatened, strike, work stoppage, material unfair labor practice
claim or other material labor dispute against or affecting any Covered Person or
its employees, which is reasonably likely to have a Material Adverse Effect.

         5.08     NO MATERIAL PROCEEDINGS. There are no Material Proceedings
pending or, to the best knowledge of Company, threatened, other than as
described in item Schedule 5.08, copies of which have been furnished to
Administrative Agent.

         5.09     MATERIAL LICENSES. All Material Licenses have been obtained or
exist for each Covered Person.

foregoing:

         (a)      GENERAL COMPLIANCE WITH ENVIRONMENTAL LAWS. The operations and
employee compensation practices of every Covered Person comply in all material
respects with all applicable Environmental Laws, the failure to comply with
which is reasonably likely to have a Material Adverse Effect.

         (b)      PROCEEDINGS. None of the operations of any Covered Person are
the subject of any judicial or administrative complaint, order or proceeding
alleging the violation of any applicable Environmental Laws.

         (c)      INVESTIGATIONS REGARDING HAZARDOUS MATERIALS. None of the
operations of any Covered Person are the subject of investigation by any
Governmental Authority regarding the improper transportation, storage, disposal,
generation or release into the environment of any Hazardous Material.

         (d)      NOTICES AND REPORTS REGARDING HAZARDOUS MATERIALS. No notice
or report under any Environmental Law indicating a past or present spill or
release into the environment of any Hazardous Material from any property owned
or operated by a Covered Person has been filed within the immediately preceding

Covered Person, to the extent such spill or release had or will have a Material
Adverse Effect.

         (e)      HAZARDOUS MATERIALS ON REAL PROPERTY. No Covered Person, nor
to Company's knowledge, any other Person, has at any time transported, stored,
disposed of, generated or released any Hazardous Material on the surface, below
the surface, or within the boundaries of any real property owned or operated by
such Covered Person, which event is reasonably likely to have a Material Adverse
Effect. Company has no knowledge of any Hazardous Material on the surface, below
the surface, or within the boundaries of any real property owned or operated by
such Covered Person, which is reasonably likely to have a Material Adverse
Effect. No property of such Covered Person is subject to a Security Interest in
favor of any Governmental Authority for any liability under any Environmental
Law or damages arising from or costs included by such Governmental Authority in
response to a spill or release of Hazardous Material into the environment.

flows of Company as of the date and for the periods stated therein.

         5.12     NO CHANGE IN CONDITION. Since September 30, 2002, there has
been no change which is reasonably likely to have a Material Adverse Effect.

         5.13     NO DEFAULTS. No Covered Person has breached or violated or has
defaulted under any Material Agreement, or has defaulted with respect to any
Material Obligation of such Covered Person. No Default or Event of Default
exists.

         5.14.    TAX LIABILITIES; GOVERNMENTAL CHARGES. Each Covered Person has
filed or caused to be filed all tax reports and returns required to be filed by
it with any Governmental Authority, except where extensions have been properly
obtained or where failure to file is not reasonably likely to have a Material
Adverse Effect. Each Covered Person has paid or made adequate provision for
payment of all Taxes of such Covered Person, except (a) Taxes which are being
diligently contested in good faith by appropriate proceedings and as to which
such Covered Person has established adequate reserves in conformity with GAAP or
(b) where failure to pay is not reasonably likely to have a Material Adverse
Effect. No Security Interests for any such Taxes has been filed and no claims
are being asserted with respect to any such Taxes which, if adversely
determined, are reasonably likely to have a Material Adverse Effect. There are
no material unresolved issues concerning any liability of a Covered Person for
any Taxes which, if adversely determined, are reasonably like to have a Material
Adverse Effect.

         5.15     PENSION BENEFIT PLANS. All Pension Benefit Plans maintained by
each Covered Person or an ERISA Affiliate of such Covered Person qualify under
Section 401 of the Code and are in compliance in all material respects with the
provisions of ERISA. Except with respect to events or occurrences which do not
have and are not reasonably likely to have a Material Adverse Effect:

has participated in, engaged in or been a party to any non exempt prohibited
transaction as defined in ERISA or the Code, and no officer, director or
employee of a Covered Person or of an ERISA Affiliate of such Covered Person has
committed a breach of any of the responsibilities or obligations imposed upon
fiduciaries by Title I of ERISA.

         (b)      CLAIMS. Other than normal claims for benefits, there are no
claims, pending or threatened, involving any such Pension Benefit Plan by a
current or former employee (or beneficiary thereof) of such Covered Person or
ERISA Affiliate of such Covered Person, nor is there any reasonable basis to
anticipate any claims involving any such Pension Benefit Plan which would likely
be successfully maintained against such Covered Person or ERISA Affiliate of
such Covered Person.

         (c)      REPORTING AND DISCLOSURE REQUIREMENTS. There are no violations
of any reporting or disclosure requirements with respect to any such Pension
Benefit Plan and none of such Pension Benefit Plans has violated any applicable
Law, including ERISA and the Code.

Plan with respect to which a Reportable Event (to the extent that the reporting
of such events to the PBGC within thirty days of the occurrence has not been

<PAGE>

waived) has occurred and is continuing; or (iii) been a Pension Benefit Plan
with respect to which there exist conditions or events which have occurred that
present a significant risk of termination of such Pension Benefit Plan by the
PBGC.

         (e)      MULTI EMPLOYER PLAN. No Covered Person or ERISA Affiliate of
such Covered Person has received notice that any Multi Employer Plan to which
any Covered Person contributes or is obligated to contribute is in

and no such Multi Employer Plan is reasonably expected to be in reorganization
or to be terminated within the meaning of Title IV of ERISA.

         5.16     EMPLOYEE BENEFIT PLANS. N Covered Person or ERISA Affiliate of
such Covered Person maintains an employee benefit plan that has a liability
which, if enforced or collected, would have a Material Adverse Effect. Each
Covered Person and ERISA Affiliate of such Covered Person has complied in all
material respects with the applicable requirements of Section 4980B of the Code
pertaining to continuation coverage as mandated by COBRA.

         5.17     STATE OF PROPERTY. Each Covered Person has good and marketable
or merchantable title to all real and personal property purported to be owned by
it or reflected in the Initial Financial Statements, except for property sold in
the ordinary course of business after the date of the Initial Financial

property purported to be owned by any Covered Person except Security Interests

meaning of Regulation U), and none of the proceeds of any Loan will be used to

the contrary, no Borrower Party shall be construed as having made any
representation, warranty or covenant with respect to any projection or forecast,
or the achievement thereof, except that whenever Company or its Subsidiaries

Document, to the best knowledge of Company when delivered, the assumptions set

of Default other than an Event of Default described in Section 8.01(g):

                  (i)      Requisite Lenders may request Administrative Agent
         to, and Administrative Agent thereupon shall, terminate the Commitments
         and/or declare all or any part of the unpaid principal of all Loans,
         all interest accrued and unpaid thereon and all other amounts payable
         under the Loan Documents to be immediately due and payable, whereupon
         the same shall become and be immediately due and payable, without
         protest, presentment, notice of dishonor, demand or further notice of
         any kind, all of which are expressly waived by each Borrower Party; and

                  (ii)     Issuing Lender may, with the approval of
         Administrative Agent on behalf of Requisite Lenders, but subject to
         Section 2.03(b), demand immediate payment by Borrower of an amount
         equal to the aggregate amount of all outstanding Letter of Credit Usage
         to be held in a Letter of Credit Cash Collateral Account.

         (b)      Upon the occurrence of any Event of Default described in
Section 8.01(g):

                  (i)      the Commitments (including the Swing Line Commitment)
         and all other obligations of Administrative Agent, Bank of America or
         other Lenders shall automatically

<PAGE>

         terminate without notice to or demand upon any Borrower Party, which
         are expressly waived by Borrower;

                  (ii)     the unpaid principal of all Loans, all interest
         accrued and unpaid thereon and all other amounts payable under the Loan
         Documents shall be immediately due and payable, without protest,
         presentment, notice of dishonor, demand or further notice of any kind,
         all of which are expressly waived by each Borrower Party; and

                  (iii)    subject to Section 2.03(b), an amount equal to the
         aggregate amount of all outstanding Letter of Credit Usage shall be
         immediately due and payable to Issuing Lender without notice to or
         demand upon any Borrower Party, which are expressly waived by each
         Borrower Party, to be held in a Letter of Credit Cash Collateral
         Account.

         (c)      Upon the occurrence of any Event of Default, Lenders and
Administrative Agent, or any of them, without notice to (except as expressly
provided for in any Loan Document) or demand, which are expressly waived by each
Borrower Party (except as to notices expressly provided for in any Loan
Document), may proceed to (but only with the consent of Requisite Lenders)
protect, exercise and enforce their rights and remedies under the Loan Documents
against any Borrower Party and such other rights and remedies as are provided by
Law or equity.

         (d)      Except as permitted by Section 10.05, no Lender may exercise
any rights or remedies with respect to the Obligations without the consent of
Requisite Lenders in their sole and absolute discretion. The order and manner in
which Administrative Agent's and Lenders' rights and remedies are to be
exercised shall be as determined by Requisite Lenders in their sole and absolute
discretion. Regardless of how a Lender may treat payments for the purpose of its
own accounting, for the purpose of computing the Obligations hereunder, payments
shall be applied first, to costs and expenses (including Attorney Costs)
incurred by Administrative Agent and each Lender, second, to the payment of
accrued and unpaid interest on the Loans to and including the date of such
application, third, to the payment of the unpaid principal of the Loans, and
fourth, to the payment of all other amounts (including fees) then owing to
Administrative Agent and Lenders under the Loan Documents, in each case paid pro
rata to each Lender in the same proportions that the aggregate Obligations owed
to each Lender under the Loan Documents bear to the aggregate Obligations owed
under the Loan Documents to all Lenders, without priority or preference among
Lenders. No application of payments will cure any Event of Default, or prevent
acceleration, or continued acceleration, of amounts payable and the Loan
Documents, or prevent the exercise, or continued exercise, of rights or remedies
of Administrative Agent and Lenders hereunder or thereunder or at Law or in
equity.

                                   SECTION 9.
                              ADMINISTRATIVE AGENT

         9.01     APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

         (a)      Each Lender hereby irrevocably (subject to Section 9.09)
appoints, designates and authorizes Administrative Agent to take such action on
its behalf under the provisions of this Agreement and each other Loan Document
and to exercise such powers and perform such duties as are expressly delegated
to it by the terms of this Agreement or any other Loan Document, together

<PAGE>

with such powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary contained elsewhere in this Agreement or in any other
Loan Document, Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall
Administrative Agent have or be deemed to have any fiduciary relationship with
any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against Administrative Agent. Without limiting the
generality of the foregoing sentence, the use of the term "agent" in this
Agreement with reference to Administrative Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.

         (b)      Issuing Lender shall act on behalf of Lenders with respect to
any Letters of Credit issued by it and the documents associated therewith until
such time and except for as long as Administrative Agent may agree at the
request of Requisite Lenders to act for such Issuing Lender with respect
thereto; provided, however, that Issuing Lender shall have all of the benefits
and immunities (i) provided to Administrative Agent in this Section 9 with
respect to any acts taken or omissions suffered by Issuing Lender in connection
with Letters of Credit issued by it or proposed to be issued by it and the
application and agreements for letters of credit pertaining to the Letters of
Credit as fully as if the term "Administrative Agent" as used in this Section 9
included Issuing Lender with respect to such acts or omissions, and (ii) as
additionally provided in this Agreement with respect to Issuing Lender.

         9.02     DELEGATION OF DUTIES. Administrative Agent may execute any of
its duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. Administrative Agent shall not
be responsible for the negligence or misconduct of any agent or attorney in fact
that it selects in the absence of gross negligence or willful misconduct.

         9.03     LIABILITY OF ADMINISTRATIVE AGENT. No Administrative
Agent-Related Person shall (a) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement or any other
Loan Document or the transactions contemplated hereby (except for its own gross
negligence or willful misconduct in connection with its duties expressly set
forth herein), or (b) be responsible in any manner to any Lender for an recital,
statement, representation or warranty made by any Borrower Party or any officer
thereof, contained in this Agreement or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by Administrative Agent under or in connection with, this Agreement
or any other Loan Document, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of any Borrower Party or any other party to any Loan Document to
perform its obligations hereunder or thereunder. No Administrative Agent-Related
Person shall be under any obligation to any Lender to ascertain or to inquire as
to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties,. books or records of any Borrower Party or any Subsidiary or
Affiliate thereof.

<PAGE>

         9.04     RELIANCE BY ADMINISTRATIVE AGENT.

         (a)      Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to any Borrower Party), independent accountants
and other experts selected by Administrative Agent. Administrative Agent shall
be fully justified in failing or refusing to take any action under any Loan
Document unless it shall first receive such advice or concurrence of Requisite
Lenders as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by Lenders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any other Loan
Document in accordance with a request or consent of Requisite Lenders or all
Lenders, if required hereunder, and such request and any action taken or failure
to act pursuant thereto shall be binding upon all of Lenders. Where this
Agreement expressly permits or prohibits an action unless Requisite Lenders
otherwise determine, and in all other instances, Administrative Agent may, but
shall not be required to, initiate any solicitation for the consent or a vote of
Lenders.

         (b)      For purposes of determining compliance with the conditions
specified in Section 4.01, each Lender shall be deemed to have consented to,
approved or accepted or to be satisfied with, each document or other matter
either sent by Administrative Agent to such Lender for consent, approval,
acceptance or satisfaction, or required thereunder to be consented to or
approved by or acceptable or satisfactory to such Lender.

         9.05     NOTICE OF DEFAULT. Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to Administrative Agent for the account of Lenders, unless
Administrative Agent shall have received written notice from a Lender or Company
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". Administrative Agent will
notify Lenders of its receipt of any such notice. Administrative Agent shall
take such action with respect to such Default or Event of Default as may be
directed by Requisite Lenders in accordance with Section 8; provided, however,
that unless and until Administrative Agent has received any such direction,
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of Lenders.

         9.06     CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Administrative Agent-Related Person has
made any representation or warranty to it, and that no act by Administrative
Agent hereinafter taken, including any consent to and acceptance of any
assignment or review of the affairs of any Borrower Party or any of its
Subsidiaries or Affiliates, shall be deemed to constitute any representation or
warranty by any Administrative Agent-Related Person to any Lender as to any
matter, including whether Administrative Agent-Related Persons have disclosed
material information in their possession. Each Lender, including any Lender by
assignment, represents to Administrative Agent that it has, independently and
without reliance upon any Administrative Agent-Related Person and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and

<PAGE>

investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of any Borrower Party and its Subsidiaries
and Affiliates, and all applicable bank regulatory laws relating to the
transactions contemplated hereby, and made its written decision to enter into
this Agreement and to extend credit to any Borrower Party hereunder. Each Lender
also represents that it will, independently and without reliance upon any
Administrative Agent-Related Person and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigations as it
deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of any Borrower
Party and its Subsidiaries and Affiliates. Except for notices, reports and other
documents expressly required to be furnished to Lenders by Administrative Agent
herein, Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of any Borrower Party or any of its Subsidiaries or Affiliates
which may come into the possession of any Administrative Agent-Related Person.

         9.07     INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, Lenders shall indemnify upon
demand each Administrative Agent-Related Person (to the extent not reimbursed by
or on behalf of any Borrower Party and without limiting the obligation of any
Borrower Party to do so), pro rata, and hold harmless each Administrative
Agent-Related Person from and against any and all Indemnified Liabilities
incurred by it; provided, however, that no Lender shall be liable for the
payment to any Administrative Agent-Related Person of any portion of such
Indemnified Liabilities resulting from such Person's gross negligence or willful
misconduct; provided, however, that no action taken in accordance with the
directions of Requisite Lender shall be deemed to constitute gross negligence or
willful misconduct for purposes of this Section. Without limitation of the
foregoing, each Lender shall reimburse Administrative Agent upon demand for its
ratable share of any costs or out of pocket expenses (including Attorney Costs)
incurred by Administrative Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement, any other Loan
Document, or any document contemplated by or referred to herein, to the extent
that Administrative Agent is not reimbursed for such expenses by or on behalf of
any Borrower Party. The undertaking in this Section shall survive the payment of
all Obligations hereunder and the resignation or replacement of Administrative
Agent.

         9.08     ADMINISTRATIVE AGENT IN INDIVIDUAL CAPACITY. Bank of America
and its Affiliates may make loans to, issue letters of credit for the account
of, accept deposits from, acquire equity interests in and generally engage in
any kind of banking, trust, financial advisory, underwriting or other business
with any Borrower Party and its Subsidiaries and Affiliates as though Bank of
America were not Administrative Agent or Issuing Lender hereunder and without
notice to or consent of Lenders. Lenders acknowledge that, pursuant to such
activities, Bank of America or its Affiliates may receive information regarding
any Borrower Party or its Affiliates (including information that may be subject
to confidentiality obligations in favor of any Borrower Party or such Affiliate)
and acknowledge that Administrative Agent shall be under no obligation to
provide such information to them. With respect to its Loans, Bank of America
shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not Administrative Agent or Issuing
Lender.

<PAGE>

         9.09     SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may, and
at the request of Requisite Lenders shall, resign as Administrative Agent upon
30 days' notice to Lenders. If Administrative Agent resigns under this
Agreement, Requisite Lenders shall appoint from among Lenders a successor
administrative agent for Lenders which successor administrative agent shall be
subject to the prior written consent of Company at all times other than during
the existence of an Event of Default (which approval of Company shall not be
unreasonably withheld or delayed). If no successor administrative agent is
appointed prior to the effective date of the resignation of Administrative
Agent, Administrative Agent may appoint, after consulting with Lenders and
Company, a successor administrative agent from among Lenders, subject to the
prior written consent of Company at all times other than during the existence of
an Event of Default (which approval of Company shall not be unreasonably
withheld or delayed). Upon the acceptance of its appointment as successor
administrative agent hereunder, such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent and the term "Administrative Agent" shall mean such successor
administrative agent and the retiring Administrative Agent's appointment, powers
and duties as Administrative Agent shall be terminated. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Section 9 and Sections 10.03 and 10.13 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and Lenders shall perform all of the duties of Administrative Agent hereunder
until such time, if any, as Requisite Lenders appoint a successor agent as
provided for above. Notwithstanding the foregoing, however, Bank of America may
not be removed as Administrative Agent at the request of Requisite Lenders
unless Bank of America shall also simultaneously be replaced as "Issuing Lender"
hereunder pursuant to documentation in form and substance reasonably
satisfactory to Bank of America.

                                   SECTION 10.
                                  MISCELLANEOUS

         10.01    AMENDMENTS; CONSENTS. (a) No amendment, modification,
supplement, extension, termination or waiver of any provision of this Agreement
or any other Loan Document, no approval or consent thereunder, and no consent to
any departure by any Borrower Party therefrom shall be effective unless in
writing signed by Borrower and Requisite Lenders and acknowledged by
Administrative Agent, and each such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given. Except as
otherwise expressly provided herein, without the approval in writing of
Administrative Agent and all Lenders, no amendment, modification, supplement,
termination, waiver or consent may be effective to:

                  (i)      Reduce the amount of principal or required principal
         payments or prepayments of any Outstanding Obligations;

                  (ii)     Reduce the rate of interest payable on any
         Outstanding Obligations or the amount of any fee or other amount
         payable to any Lender under the Loan Documents (unless consented to by
         each Lender entitled to receive such fee or other amount), including in
         each case, any change in the way any financial covenant used to
         determine the Applicable Amount is calculated;

<PAGE>

                  (iii)    Waive an Event of Default consisting of the failure
         of Borrower to pay when due principal, interest or any commitment fee;

                  (iv)     Postpone any date fixed for any payment of principal
         of, prepayment of principal of, or any installment of interest on, any
         Loan or any installment of any commitment fee, to extend the term of,
         or increase the amount of, any Lender's Commitment or the Swing Line
         Commitment (it being understood that a waiver of any Event of Default
         not referred to in subsection (iii) above shall require only the
         consent of Required Lenders) or modify the Pro Rata Share of any
         Lender;

                  (v)      Amend the definition of "Requisite Lenders" or the
         provisions of Section 4, Section 9, this Section 10.01 or Section
         10.06; or

                  (vi)     Amend any provision of this Agreement that expressly
         requires the consent or approval of all Lenders;

writing and signed by Issuing Lender in addition to Requisite Lenders or all
Lenders, as the case may be, affect the rights or duties of Issuing Lender, (y)
no amendment, waiver or consent shall, unless in writing and signed by
Administrative Agent in addition to Requisite Lenders or all Lenders as the case
may be, affect the rights or duties of Administrative Agent, and (z) any fee
letters may be amended, or rights or privileges thereunder waived, in a writing
executed by the parties thereto. Any amendment, modification, supplement,
termination, waiver or consent pursuant to this Section shall apply equally to,
and shall be binding upon, all Lenders and Administrative Agent.

         (b)      Each Lender acknowledges and agrees that the Note Purchase
Agreement-2003 has not been executed and the notes thereunder issued as of the
date of this Agreement. The Note Purchase Agreement-2003 is listed as a
Permitted Indebtedness on Schedule 5.24. Provided the terms of the Note Purchase
Agreement-2003 conform to the parameters set forth below, each Lender authorizes
the Administrative Agent to sign and deliver any necessary or appropriate

Administrative Agent.

         (b)      RELIANCE BY ADMINISTRATIVE AGENT AND LENDERS. Administrative
Agent and Lenders shall be entitled to rely and act on any communications
purportedly given by or on behalf of any Borrower Party even if (i) such
communications (A) were not made in a manner specified herein, (B) were
incomplete or (C) were not preceded or followed by any other notice specified
herein, or (ii) the terms thereof, as understood by the recipient, varied from
any subsequent related communications provided for herein. Company shall
indemnify Administrative Agent and Lenders from any loss, cost, expense or
liability as a result of relying on any communications permitted herein.

         (c)      EFFECTIVENESS OF FACSIMILE DOCUMENTS AND SIGNATURES. Loan
Documents may be transmitted and/or signed by facsimile. The effectiveness of
any such document and signatures shall, subject to applicable Law, have the same
force and effect as hard-copies with manual signatures and shall be binding on
all Borrower Parties and Administrative Agent and Lenders. Administrative Agent
may also require that any such documents and signatures be confirmed by a
manually signed hardcopy thereof; provided, however, that the failure to request
or deliver any such manually signed hardcopy shall not affect the effectiveness
of any facsimile document or signature.

         (d)      EFFECTIVENESS OF ELECTRONIC MAIL. Electronic mail may be used
to distribute routine communications, such as financial statements and other
information and to distribute agreements and other documents to be signed by
Lenders; provided, however, that no Request for Extension of Credit or executed
or legally-binding notice, agreement, waiver, amendment or other communication
may be sent by electronic mail.

         10.03    ATTORNEY COSTS, EXPENSES AND TAXES. Company agrees (a) to pay
or reimburse Administrative Agent for all costs and expenses incurred in
connection with the development, preparation, negotiation and execution of any
amendment, waiver, consent, supplement or modification requested by Company to,
any Loan Documents, and any other documents prepared in connection therewith,
including all Attorney Costs, and (b) after the occurrence of a Default or

<PAGE>

Event of Default (whether or not waived) or in connection with transactions
requested by Company, to pay or reimburse Administrative Agent and each Lender
for all costs and expenses incurred in connection with any refinancing,
restructuring, reorganization (including a bankruptcy reorganization) and
enforcement or attempted enforcement, or preservation of any rights under any
Loan Documents, and any other documents prepared in connection herewith or
therewith, or in connection with any refinancing, or restructuring of any such
documents in the nature of a "workout" or of any insolvency or bankruptcy
proceeding, including Attorney Costs. The foregoing costs and expenses shall
include all search, filing, recording, title insurance and appraisal charges and
fees and taxes related thereto, and other out of pocket expenses incurred by
Administrative Agent and the cost of independent public accountants and other
outside experts retained by Administrative Agent or any Lender. The agreements
in this Section shall survive repayment of all Obligations.

         10.04    BINDING EFFECT; ASSIGNMENT.

         (a)      This Agreement and the other Loan Documents to which a
Borrower Party is a party will be binding upon and inure to the benefit of each
Borrower Party, Administrative Agent, Lenders and their respective successors
and assigns, except that, no Borrower Party may assign its rights hereunder or
thereunder or any interest herein or therein without the prior written consent
of all Lenders and any such attempted assignment shall be void. Any Lender may
at any time pledge its Note or any other instrument evidencing its rights as a
Lender under this Agreement to a Federal Reserve Bank, but no such pledge shall
release such Lender from its obligations hereunder or grant to such Federal
Reserve Bank the rights of a Lender hereunder absent foreclosure of such pledge.

         (b)      From time to time following the Closing Date, each Lender may
assign to one or more Eligible Assignees all or any portion of its Commitment
and/or Extensions of Credit; provided that (i) such assignment, if not to a
Lender or an Affiliate of the assigning Lender, shall be subject to the prior
written consent of Company at all times other than during the existence of a
Default or Event of Default and by Administrative Agent, and Issuing Lender
(which approval of Company shall not be unreasonably withheld or delayed), (ii)
a copy of a duly signed and completed Assignment and Acceptance shall be
delivered to Administrative Agent, (iii) except in the case of an assignment (A)
to an Affiliate of the assigning Lender or to another Lender or (B) of the
entire remaining Commitment of the assigning Lender, the portion of the
Commitment assigned shall not be less than $5,000,000, (iv) the effective date
of any such assignment shall be as specified in the Assignment and Acceptance,
but not earlier than the date which is five Business Days after the date
Administrative Agent has received the Assignment and Acceptance and (v) such
assignee Lender shall become a "Creditor" under and as defined in the
Intercreditor Agreement by executing and delivering a counterpart thereof and
complying with the provisions thereof. Upon obtaining any consent required as
set forth in the prior sentence and payment of the requisite fee described
below, the assignee named therein shall be a Lender for all purposes of this
Agreement, with the Pro Rata Share therein set forth and, to the extent of such
Pro Rata Share, the assigning Lender shall be released from its further
obligations under this Agreement. Borrower agrees that it shall execute and
deliver upon request (against delivery by the assigning Lender to Borrower of
any Note) to such assignee Lender, one or more Notes evidencing such assignee
Lender's Loans, and to the assigning Lender, if requested, one or more Notes
evidencing Loans under any Commitment retained by the assigning Lender.
Administrative Agent's consent to any assignment shall not be deemed to
constitute any representation or warranty by any Administrative Agent-Related
Person as to any matter. For purposes hereof, each mutual fund that is an
Affiliate of a Lender shall a deemed to be

<PAGE>

a single Eligible Assignee, whether or not such fund is managed by the same fund
manager as other mutual funds that are Affiliates of the same Lender.

         (c)      After receipt of a completed Assignment and Acceptance, and
receipt of an assignment fee of $3,500 from such Eligible Assignee (including in
the case of assignments to Affiliates of assigning Lenders), Administrative
Agent shall, promptly following the effective date thereof, provide to Company
and Lenders a revised Schedule 10.02 giving effect thereto.

         (d)      Each Lender may from time to time, without the consent of any
other Person, grant participations to one or more other Person (including
another Lender) all or any portion of its Pro Rata Share of its Commitment
and/or Extensions of Credit; provided, however, that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the participating banks or other financial institutions
shall not be a Lender hereunder for any purpose except, if the participation
agreement so provides, for the purposes of Section 3 (but only to the extent
that the cost of such benefits to Company does not exceed the cost which Company
would have incurred in respect of such Lender absent the participation) and
subject to Sections 10.05 and 10.06, (iv) Borrower, Administrative Agent and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, (v)
the participation agreement shall not restrict an increase in the combined
Commitments or in the granting Lender's Commitment or Pro Rata Share, so long as
the amount of the participation interest is not increased, and (vi) the consent
of the holder of such participation interest shall not be required for
amendments or waivers of provisions of the Loan Documents; provided, however,
that the assigning Lender may, in any agreement with a participant, give such
participant the right to consent to any matter which (A) extends the Maturity
Date as to such participant or any other date upon which any payment of money is
due to such participant, (B) reduces the rate of interest owing to such
participant, any fee or any other monetary amount owing to such participant, or
(C) reduces the amount of any installment of principal owing to such
participant. Any Lender that sells a participation to any Person that is a
"foreign corporation, partnership or trust" within the meaning of the Code shall
include in its participation agreement with such Person a covenant by such
Person that such Person will comply with the provisions of Section 10.21 as if
such Person were a Lender and provide that Administrative Agent and Borrower
shall be third party beneficiaries of such covenant.

         10.05    SET OFF. In addition to any rights and remedies of
Administrative Agent and Lenders or any assignee or participant of any Lender or
any Affiliate thereof (each a, "Proceeding Party") provided by law, upon the
occurrence and during the continuance of any Event of Default, each Proceeding
Party is authorized at any time and from time to time, without prior notice to
any Borrower Party, any such notice being waived by Borrower Parties to the
fullest extent permitted by law, to proceed directly, by right of set off,
banker's lien or otherwise, against any assets of the Borrower Parties which may
be in the hands of such Proceeding Party (including all general or special, time
or demand, provisional or other deposits and other indebtedness owing by such
Proceeding Party to or for the credit or the account of Borrower) and apply such
assets against the Obligations, irrespective of whether such Proceeding Party
shall have made any demand therefor and although such Obligations may be
unmatured. Each Lender agrees promptly to notify Company and Administrative
Agent after any such set-off and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such set off and application.

<PAGE>

         10.06    SHARING OF PAYMENTS. Each Lender agrees that if it, through
the exercise of any right of setoff, banker's lien or counterclaim against any
Borrower Party or otherwise, receives payment of the Obligations held by it that
is ratably more than any other Lender receives in payment of the Obligations
held by such other Lender, then, subject to applicable Laws: (a) such Lender
exercising the right of setoff, banker's lien or counterclaim or otherwise
receiving such payment shall purchase, and shall be deemed to have
simultaneously purchased, from the other Lender a participation in the
Obligations held by the other Lender and shall pay to the other Lender a
purchase price in an amount so that the share of the Obligations held by each
Lender after the exercise of the right of setoff, banker's lien or counterclaim
or receipt of payment shall be in the same proportion that existed prior to the
exercise of the right of setoff, banker's lien or counterclaim or receipt of
payment; and (b) such other adjustments and purchases of participations shall be
made from time to time as shall be equitable to ensure that all Lenders share
any payment obtained in respect of the Obligations ratably in accordance with
each Lender's share of the Obligations immediately prior to, and without taking
into account, the payment; provided that, if all or any portion of a
disproportionate payment obtained as a result of the exercise of the right of
setoff, banker's lien, counterclaim or otherwise is thereafter recovered from
the purchasing Lender by a Borrower Party or any Person claiming through or
succeeding to the rights of a Borrower Party, the purchase of a participation
shall be rescinded and the purchase price thereof shall be restored to the
extent of the recovery, but without interest. Each Lender that purchases a
participation in the Obligations pursuant to this Section shall from and after
the purchase have the right to give all notices, requests, demands, directions
and other communications under this Agreement with respect to the portion of the
Obligation purchased to the same extent as though the purchasing Lender were the
original owner of the Obligations purchased. Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in an
Obligation so purchased may exercise any and all rights of setoff, banker's lien
or counterclaim with respect to the participation as fully as if Lender were the
original owner of the Obligation purchased.

         10.07    NO WAIVER; CUMULATIVE REMEDIES.

         (a)      No failure by any Lender or Administrative Agent to exercise,
and no delay by any Lender or Administrative Agent in exercising, any right,
remedy, power or privilege hereunder, shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, remedy, power or privilege
under any Loan Document preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege.

         (b)      The rights, remedies, powers and privileges herein or therein
provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by Law. Any decision by Administrative Agent or any Lender
not to require payment of any interest (including Default Interest), fee, cost
or other amount payable under any Loan Document or to calculate any amount
payable by a particular method on any occasion shall in no way limit or be
deemed a waiver of Administrative Agent's or such Lender's right to require full
payment thereof, or to calculate an amount payable by another method that is not
inconsistent with this Agreement, on any other or subsequent occasion.

         (c)      Except with respect to Section 9.09, the terms and conditions
of Section 9 are for the sole benefit of Administrative Agent and Lenders.

<PAGE>

         10.08    USURY. Notwithstanding anything to the contrary contained in
any Loan Document, the interest paid or agreed to be paid under the Loan
Documents shall not exceed the maximum rate of non-usurious interest permitted
by applicable Law (the "Maximum Rate"). If Administrative Agent or any Lender
shall receive interest in an amount that exceeds the Maximum Rate, the excessive
interest shall be applied to the principal of the Outstanding Obligations or, if
it exceeds the unpaid principal, refunded to the Borrower. In determining
whether the interest contracted for, charged, or received by Administrative
Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent
permitted by applicable Law, (a) characterize any payment that is not principal
as an expense, fee, or premium rather than interest, (b) exclude voluntary
prepayments and the effects thereof, and (c) amortize, prorate, allocate, and
spread in equal or unequal parts the total amount of interest throughout the
contemplated term of the Obligations.

         10.09    COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         10.10    INTEGRATION. This Agreement, together with the other Loan
Document is and any letter agreements referred to herein, comprises the complete
and integrated agreement of the parties on the subject matter hereof and
supersedes all prior agreements, written or oral, on the subject matter hereof.
In the event of any conflict between the provisions of this Agreement and those
of any other Loan Document, the provisions of this Agreement shall control and
govern; provided that the inclusion of supplemental rights or remedies in favor
of Administrative Agent or Lenders in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

         10.11    NATURE OF LENDERS' OBLIGATIONS. Nothing contained in this
Agreement or any other Loan Document and no action taken by Administrative Agent
or Lenders or any of them pursuant hereto or thereto may, or may be deemed to,
make Lenders a partnership, an association, a joint venture or other entity,
either among themselves or with Borrower or any Affiliate of Borrower. Each
Lender's obligation to make any Extension of Credit pursuant hereto is several
and not joint or joint and several. A default by any Lender will not increase
the Pro Rata Share attributable to any other Lender.

         10.12    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder and in any other Loan Document,
certificate or statement delivered pursuant hereto or thereto or in connection
herewith or therewith shall survive the execution and delivery thereof. Such
representations and warranties have been or will be relied upon by
Administrative Agent and each Lender, notwithstanding any investigation made by
Administrative Agent or any Lender or on their behalf.

         10.13    INDEMNITY BY BORROWERS.

         (a)      Borrower agrees to indemnify, save and hold harmless each
Administrative Agent-Related Person and each Lender and their respective
Affiliates, directors, officers, agents, attorneys and employees (collectively
the "Indemnitees") from and against: (i) any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person (other
than Administrative Agent or any Lender) relating directly or indirectly to a
claim, demand, action or

<PAGE>

cause of action that such Person asserts or may assert against any Borrower
Party, any of their Affiliates or any of their officers or directors; (ii) any
and all claims, demands, actions or causes of action (other than by
Administrative Agent or any Lender) arising out of or relating to, the Loan
Documents, any predecessor loan documents, the Commitments, the use or
contemplated use of the proceeds of any Loan, or the relationship of any
Borrower Party, Administrative Agent and Lenders under this Agreement; (iii) any
administrative or investigative proceeding by any Governmental Authority arising
out of or related to a claim, demand, action or cause of action described in
subsection (i) or (ii) above; and (iv) any and all liabilities, losses, costs or
expenses (including Attorney Costs) that any Indemnitee suffers or incurs as a
result of the assertion of any foregoing claim, demand, action, cause of action
or proceeding, or as a result of the preparation of any defense in connection
with any foregoing claim, demand, action, cause of action or proceeding, in all
cases, whether or not arising out of the negligence of an Indemnitee, except as
aforesaid, whether or not an Indemnitee is a party to such clam, demand, action,
cause of action or proceeding (all the foregoing, collectively, the "Indemnified
Liabilities"); provided that no Indemnitee shall be entitled to indemnification
for any loss caused by its own gross negligence or willful misconduct or for any
loss asserted against it by another Indemnitee. The foregoing indemnity shall
not extend to any indirect or consequential damages except to the extent such
damages are recoverable under a third-party claim against an Indemnitee. The
agreements in this Section shall survive repayment of all Obligations.

         (b)      Promptly after receipt by an Indemnitee of a notice of the
commencement of any action or proceeding that may give rise to indemnification
hereunder, such Indemnitee will notify Administrative Agent, who shall promptly
notify Company. Company shall have the right to undertake, conduct and control
through counsel of its own choosing (which counsel shall be reasonably
acceptable to the Indemnitees) and at the sole expense of Company, the conduct
and settlement of any Indemnified Liabilities, and the Indemnitees shall
cooperate with Company in connection therewith; provided that Company shall
permit any Indemnitee to participate in such conduct and settlement through
counsel chosen by such Indemnitee, but the fees and expenses of such counsel
shall be borne by such Indemnitee. Notwithstanding the foregoing, if the
interests of Company and any Indemnitee become adverse in any such claim or
course of action, such Indemnitee shall have the right to employ its own
counsel, and the reasonable fees and expenses of such counsel shall be at
Company's costs and expense. Borrower shall not be liable for any settlement of
any claim or action effected without its prior written consent, such consent not
to be unreasonably withheld.

         10.14    NONLIABILITY OF LENDERS. Borrower acknowledges and agrees
that:

         (a)      Any inspections of any property of any Borrower Party made by
or through Administrative Agent or Lenders are for purposes of administration of
the Loan Documents only, and Borrower is not entitled to rely upon the same
(whether or not such inspections are at the expense of Borrower);

         (b)      By accepting or approving anything required to be observed,
performed, fulfilled or given to Administrative Agent or Lenders pursuant to the
Loan Documents, neither Administrative Agent nor Lenders shall be deemed to have
warranted or represented the sufficiency, legality, effectiveness or legal
effect of the same, or of any term, provision or condition thereof, and such
acceptance or approval thereof shall not constitute a warranty or representation
to anyone with respect thereto by Administrative Agent or Lenders;

<PAGE>

         (c)      The relationship between Borrower and Administrative Agent and
Lenders is, and shall at all times remain, solely that of borrowers and lenders;
neither Administrative Agent nor any Lender shall under any circumstance be
deemed to be in a relationship of confidence or trust or a fiduciary
relationship with Borrower or its Affiliates, or to owe any fiduciary duty to
Borrower or its Affiliates; neither Administrative Agent nor any Lender
undertakes or assumes any responsibility or duty to Borrower or its Affiliates
to select, review, inspect, supervise, pass judgment upon or inform Borrower or
its Affiliates of any matter in connection with their property or the operations
of Borrower or its Affiliates; Borrower and its Affiliates shall rely entirely
upon their own judgment with respect to such matters; and any review,
inspection, supervision, exercise of judgment or supply of information
undertaken or assumed by Administrative Agent or any Lender in connection with
such matters is solely for the protection of Administrative Agent and Lenders
and neither Borrower nor any other Person is entitled to rely thereon; and

         (d)      Neither Administrative Agent nor any Lender shall be
responsible or liable to any Person for any loss, damage, liability or claim of
any kind relating to injury or death to Persons or damage to property caused by
the actions, inaction or negligence of Borrower and/or its Affiliates, and
Borrower hereby indemnifies and holds Administrative Agent and Lenders harmless
from any such loss, damage, liability or claim subject to the procedures and
limitations governing indemnification under Section 10.13.

         10.15    NO THIRD PARTIES BENEFITED. This Agreement is made for the
purpose of defining and setting forth certain obligations, rights and duties of
Borrower, Administrative Agent and Lenders in connection with the Extensions of
Credit, and is made for the sole benefit of Borrower, Administrative Agent and
Lenders, and Administrative Agent's and Lenders' successors and assigns. Except
as provided in Sections 10.04 and 10.13, no other Person shall have any rights
of any nature hereunder or by reason hereof.

         10.16    SEVERABILITY. Any provision of the Loan Documents that 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 thereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         10.17    CONFIDENTIALITY. Administrative Agent and each Lender shall
use any confidential non-public information concerning the Borrower Parties and
their Subsidiaries that is furnished to Administrative Agent or such Lender by
or on behalf of the Borrower Parties and their Subsidiaries in connection with
the Loan Documents (collectively, "Confidential Information") solely for the
purpose of evaluating and providing products and services to them and
administering and enforcing the Loan Documents, and it will hold the
Confidential Information in confidence. Notwithstanding the foregoing,
Administrative Agent and each Lender may disclose Confidential Information (a)
to their affiliates or any of their affiliates' directors, officers, employees,
auditors, counsel, advisors, or representatives (collectively, the
"Representatives") whom it determines need to know such information for the
purposes set forth in this Section; (b) to any bank or financial institution or
other entity to which such Lender has assigned or desires to assign an interest
or participation in the Loan Documents or the Obligations, provided that any
such foregoing recipient of such Confidential Information agrees to keep such
Confidential Information confidential as specified herein; (c) to any
governmental agency or regulatory body having or claiming to have authority to
regulate or oversee any aspect of Administrative Agent's or such Lender's
business or that of their

<PAGE>

Representatives in connection with the exercise of such authority or claimed
authority; (d) to the extent necessary or appropriate to effect or preserve
Administrative Agent's or such Lender's or any of their Affiliates' security (if
any) for any Obligation or to enforce any right or remedy or in connection with
any claims asserted by or against Administrative Agent or such Leader or any of
their Representatives; and (e) pursuant to any subpoena or any similar legal
process. For purposes hereof, the term "Confidential Information" shall not
include information that (x) is in Administrative Agent's or a Lender's
possession prior to its being provided by or on behalf of the Borrower Parties,
provided that such information is not known by Administrative Agent or such
Lender to be subject to another confidentiality agreement with, or other legal
or contractual obligation of confidentiality to, a Borrower Party, (y) is or
becomes publicly available (other than through a breach hereof by Administrative
Agent or such Lender), or (z) becomes available to Administrative Agent or such
Lender on a nonconfidential basis, provided that the source of such information
was not known by Administrative Agent or such Lender to be bound by a
confidentiality agreement or other legal or contractual obligation of
confidentiality with respect to such information.

         10.18    FURTHER ASSURANCES. Each Borrower Party shall, and shall cause
it Subsidiaries to, at their expense and without expense to Lenders or
Administrative Agent, do, execute and deliver such further acts and documents as
any Lender or Administrative Agent from time to time reasonably requires for the
assuring and confirming unto Lenders or Administrative Agent of the rights
hereby created or intended now or hereafter so to be, or for carrying out the
intention or facilitating the performance of the terms of any Loan Document.

         10.19    HEADINGS. Section headings in this Agreement and the other
Loan Documents are included for convenience of reference only and are not part
of this Agreement or the other Loan Documents for any other purpose.

         10.20    TIME OF THE ESSENCE. Time is of the essence of the Loan
Documents

         10.21    FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code shall deliver to
Administrative Agent and Company, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either Form W-8BEN or any successor
thereto (relating to such Person and entitling it to a complete exemption from
withholding on all payments to be made to such Person by Borrower pursuant to
this Agreement) or Form W-8ECI or any successor thereto (relating to all
payments to be made to such Person by Borrower pursuant to this Agreement) of
the IRS or such other evidence satisfactory to Borrower and Administrative Agent
that no withholding under the federal income tax laws is required with respect
to such Person. Thereafter and from time to time, each such Person shall (a)
promptly submit to Administrative Agent and Company such additional duly
completed and signed copies of one of such forms (or such successor forms as
shall be adopted from time to time by the relevant United States taxing
authorities) as may then be available under then current United States laws and
regulations to avoid, or such evidence as is satisfactory to Borrower and
Administrative Agent of any available exemption from, United States withholding
taxes in respect of all payments to be made to such Person by Borrower pursuant
to this Agreement, and (b) take such steps as shall not be materially
disadvantageous to it, in the reasonable judgment of such Lender, and as may be
reasonably necessary (including the re-designation of its Lending Office) to
avoid any requirement of applicable Laws that Borrower make any deduction or
withholding for taxes from amounts

<PAGE>

payable to such Person. If such Persons fails to deliver the above forms or
other documentation, then Administrative Agent or Borrower may withhold from any
interest payment to such Person an amount equivalent to the applicable
withholding tax imposed by Sections 1441 and 1442 of the Code, without
reduction. If any Governmental Authority asserts that Administrative Agent or
Borrower did not properly withhold any tax or other amount from payments made in
respect of such Person, such Person shall indemnify Administrative Agent
therefor, including all penalties and interest and costs and expenses (including
Attorney Costs) of Administrative Agent and Borrower. The obligation of Lenders
under this Section shall survive the payment of all Obligations and the
resignation or replacement of Administrative Agent.

         10.22    COMPELLED RETURN OF PAYMENTS OR PROCEEDS. If Administrative
Agent or any Lender is for any reason compelled to surrender any payment from
Borrower because such payment is for any reason invalidated, declared
fraudulent, set aside, or determined to be void or voidable as a preference, an
impermissible setoff, or a diversion of trust funds, then each Loan Document and
the Obligations to which such payment was applied or intended to be applied
shall be revived with respect thereto as if such application was never made; and
Borrower shall be liable to pay to Administrative Agent and Lenders, and shall
indemnify Administrative Agent and Lenders for, and hold Administrative Agent
and Lenders harmless from, any loss with respect to, the amount of such payment
surrendered. This Section shall be effective notwithstanding any contrary action
Administrative Agent or any Lender may take in reliance upon its receipt of any
such payment. Any such contrary action so taken by Administrative Agent or any
Lender shall be without prejudice to Administrative Agent's and Lender's rights
under this Agreement and shall be deemed to have been conditioned upon the
application of such payment having become final and indefeasible. The provisions
of this Section shall survive termination of the Commitment, the expiration of
the Letters of Credit and the payment and satisfaction of all Obligations.
