          On May 6, 2003, the Borrower and the Guarantors filed voluntary

in Section 1.01) initiating the Cases and have continued in the possession of
their assets and in the management of their business pursuant to Sections 1107
and 1108 of the Bankruptcy Code.

          The Borrower, the Guarantors, the Existing Lenders and JPMorgan Chase,
as administrative agent, are parties to that certain Credit Agreement dated as
of May 23, 2000 (as amended or otherwise modified prior to the date hereof, the
"Existing Agreement") pursuant to which the Borrower and the Guarantors were
truly and justly indebted to the Existing Lenders on the Filing Date in respect
of the extensions of credit provided for thereunder in the principal amount of
$601,370,125.48 (including the aggregate outstanding face amount of issued but
undrawn letters of credit denominated in Dollars outstanding thereunder) and
with respect to an outstanding face amount of an issued but undrawn letter of
credit denominated in Euro in the amount of EUR83,003,011.44.

          The Borrower has applied to the Lenders for a revolving credit and
letter of credit facility in an aggregate principal amount not to exceed
$30,000,000, all of the Borrower's obligations under which are to be guaranteed
by the Guarantors.

          The proceeds of the Loans will be used for working capital and other
general corporate purposes of the Borrower and the Guarantors (including,
without limitation, to the extent permitted hereunder, for post-petition loans

Agreement and the Orders.

perfected Liens that presently secure the Borrower's and Guarantors'
pre-petition Indebtedness under the Existing Agreement) that is subject to valid

Liens in existence on the Filing Date that are perfected subsequent to the
Filing Date as permitted by Section 546(b) of the Bankruptcy Code or that is

          (e)  perfected first priority priming Liens, pursuant to Section
364(d)(1) of the Bankruptcy Code, upon all property of the Borrower and the
Guarantors that is subject to (x) the existing Liens that presently secure the

hereby are subject on the Filing Date or become subject subsequent to the Filing
Date as permitted by Section 546(b) of the Bankruptcy Code) and (y) any Liens
granted after the Filing Date to provide adequate protection in respect of the

SECTION 2  AMOUNT AND TERMS OF CREDIT

     SECTION 2.01.  Commitments of the Lenders.

          (a)  Each Lender severally and not jointly with the other Lenders
agrees, upon the terms and subject to the conditions herein set forth
(including, without limitation, the provisions of Section 2.28), to make
revolving credit loans (each a "Loan" and collectively, the "Loans") to the
Borrower at any time and from time to time during the period commencing on the
date hereof and ending on the Termination Date in an aggregate principal amount
not to exceed, when added to such Lender's Commitment Percentage of the then
aggregate Letter of Credit Outstandings (in excess of the amount of cash then
held in the Letter of Credit Account pursuant to Section 2.03(c)), the
Commitment of such Lender, which Loans may be repaid and reborrowed in
accordance with the provisions of this Agreement. At no time shall the sum of
the then outstanding aggregate principal amount of the Loans plus the then
aggregate Letter of Credit Outstandings exceed the least of (i) the Total
Commitment of up to $30,000,000, as the same may be reduced from time to time
pursuant to Section 2.10 and Section 2.13, (ii) the Borrowing Base and (iii) the
Maximum Outstanding Amount.

          (b)  Each Borrowing shall be made by the Lenders in accordance with
their respective Commitment Percentages; provided, however, that the failure of
any Lender to make any Loan shall not in itself relieve the other Lenders of
their obligations to lend.

     SECTION 2.02. Borrowing Base. Notwithstanding any other provision of this
Agreement to the contrary, the aggregate principal amount of all outstanding
Loans, plus the then aggregate Letter of Credit Outstandings (in excess of the
amount of cash then held in the Letter of Credit Account pursuant to Section
2.03(c)) shall not at any time exceed the Borrowing Base and no Loan shall be
made or Letter of Credit issued in violation of the foregoing.

     SECTION 2.03.  Letters of Credit.

          (a)  Upon the terms and subject to the conditions herein set forth,
the Borrower may request a Fronting Bank, at any time and from time to time
after the date hereof and prior to the Termination Date, to issue, and, subject
to the terms and conditions contained herein, such Fronting Bank shall issue,
for the account of the Borrower or a Guarantor one or more Letters of Credit
(the "Letters of Credit"), provided that no Letter of Credit shall be issued if
after giving effect to such issuance (i) the aggregate Letter of Credit
Outstandings shall exceed $10,000,000 (or such lesser maximum amount permitted
to be outstanding pursuant to the Interim Order) or (ii) the aggregate Letter of
Credit Outstandings, when added to the aggregate outstanding principal amount of
the Loans, would exceed the least of (x) the Total Commitment, (y) the Borrowing
Base and (z) the Maximum Outstanding Amount and, provided further that no Letter
of Credit shall be issued if the Fronting Bank shall have received notice from
the Agent or the Required Lenders that the conditions to such issuance have not
been met.

          (b)  No Letter of Credit shall expire later than the Maturity Date,
provided, that if any Letter of Credit shall be outstanding on the Termination
Date, the Borrower shall, at or prior to the Termination Date, except as the
Agent may otherwise agree in writing, (i) cause all Letters of Credit which
expire after the Termination Date to be returned to the Fronting Bank

                                       27

<PAGE>

undrawn and marked "cancelled" or (ii) if the Borrower is unable to do so in
whole or in part, either (x) provide a "back-to-back" letter of credit to one or
more Fronting Banks in a form satisfactory to such Fronting Bank and the Agent
(in their sole discretion), issued by a bank satisfactory to such Fronting Bank
and the Agent (in their sole discretion), and in an amount equal to 105% of the
then undrawn stated amount of all outstanding Letters of Credit issued by such
Fronting Banks (less the amount, if any, then on deposit in the Letter of Credit
Account) or (y) deposit cash in the Letter of Credit Account in an amount equal
to 105% of the then undrawn stated amount of all Letter of Credit Outstandings
(less the amount, if any, then on deposit in the Letter of Credit Account) as
collateral security for the Borrower's reimbursement obligations in connection
therewith, such cash to be remitted to the Borrower upon the expiration,
cancellation or other termination or satisfaction of such reimbursement
obligations ("Cash Collateralization").

          (c)  The Borrower shall pay to each Fronting Bank, in addition to
such other fees and charges as are specifically provided for in Section 2.21
hereof, such fees and charges in connection with the issuance and processing of
the Letters of Credit issued by such Fronting Bank as are customarily imposed by
such Fronting Bank from time to time in connection with letter of credit
transactions.

          (d)  Drafts drawn under each Letter of Credit shall be reimbursed by
the Borrower in Dollars not later than the first Business Day following the date
of draw and shall bear interest (i) from the date of draw until the first
Business Day following the date of draw at a rate per annum equal to the
Alternate Base Rate plus the Applicable Margin and (ii) thereafter on the
unreimbursed portion until reimbursed in full at the rate per annum equal to the
Alternate Base Rate plus the Applicable Margin plus 2.00% (computed on the basis
of the actual number of days elapsed over a year of 365 days or 366 days in a
leap year). The Borrower shall effect such reimbursement (x) if such draw occurs
prior to the Termination Date, in cash or through a Borrowing, without the
satisfaction of the conditions precedent set forth in Section 4.02 or (y) if
such draw occurs on or after the Termination Date, in cash. Each Lender agrees
to make the Loans, described in clause (x) of the preceding sentence
notwithstanding a failure to satisfy the applicable lending conditions thereto
or the provisions of Sections 2.02 or 2.28.

          (e)  Immediately upon the issuance of any Letter of Credit by any
Fronting Bank, such Fronting Bank shall be deemed to have sold to each Lender
(other than such Fronting Bank) and each such other Lender shall be deemed
unconditionally and irrevocably to have purchased from such Fronting Bank,
without recourse or warranty, an undivided interest and participation, to the
extent of such Lender's Commitment Percentage, in such Letter of Credit, each
drawing thereunder and the obligations of the Borrower and the Guarantors under
this Agreement with respect thereto. Upon any change in the Commitments pursuant
to Section 11.03, it is hereby agreed that with respect to all Letter of Credit
Outstandings, there shall be an automatic adjustment to the participations
hereby created to reflect the new Commitment Percentage of the assigning and
assignee Lenders. Any action taken or omitted by a Fronting Bank under or in
connection with a Letter of Credit, if taken or omitted in the absence of gross
negligence or willful misconduct, shall not create for such Fronting Bank any
resulting liability to any other Lender.

          (f)  In the event that a Fronting Bank makes any payment under any
Letter of Credit and the Borrower shall not have reimbursed such amount in full
to such Fronting Bank

                                       28

<PAGE>

pursuant to this Section, the Fronting Bank shall promptly notify the Agent,
which shall promptly notify each Lender, of such failure, and each such Lender
shall promptly and unconditionally pay to the Agent for the account of the
Fronting Bank the amount of such Lender's Commitment Percentage of such
unreimbursed payment in Dollars and in same day funds. If the Fronting Bank so
notifies the Agent, and the Agent so notifies the Lenders prior to 11:00 a.m.
(New York City time) on any Business Day, such Lenders shall make available to
the Fronting Bank such Lender's Commitment Percentage of the amount of such
payment on such Business Day in same day funds. If and to the extent such Lender
shall not have so made its Commitment Percentage of the amount of such payment
available to the Fronting Bank, such Lender agrees to pay to such Fronting Bank,
forthwith on demand such amount, together with interest thereon, for each day
from such date until the date such amount is paid to the Agent for the account
of such Fronting Bank at the Federal Funds Effective Rate. The failure of any
Lender to make available to the Fronting Bank its Commitment Percentage, of any
payment under any Letter of Credit shall not relieve any other Lender of its
obligation hereunder to make available to the Fronting Bank its Commitment
Percentage, of any payment under any Letter of Credit on the date required, as
specified above, but no Lender shall be responsible for the failure of any other
Lender to make available to such Fronting Bank such other Lender's Commitment
Percentage of any such payment. Whenever a Fronting Bank receives a payment of a
reimbursement obligation as to which it has received any payments from the
Lenders pursuant to this paragraph, such Fronting Bank shall pay to the Agent
for the account of each Lender which has paid its Commitment Percentage thereof,
in Dollars and in same day funds, an amount equal to such Lender's Commitment
Percentage thereof.

     SECTION 2.04.  Issuance. Whenever the Borrower desires a Fronting Bank to
issue a Letter of Credit, it shall give to such Fronting Bank and the Agent
prior written (including telegraphic, telex, facsimile or cable communication)
notice reasonably in advance of the requested date of issuance specifying the
date on which the proposed Letter of Credit is to be issued (which shall be a
Business Day), the stated amount of the Letter of Credit so requested, the
expiration date of such Letter of Credit and the name and address of the
beneficiary thereof.

     SECTION 2.05.  Nature of Letter of Credit Obligations Absolute. The
obligations of the Borrower to reimburse the Lenders for drawings made under any
Letter of Credit shall be unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances,
including, without limitation (it being understood that any such payment by the
Borrower shall be without prejudice to, and shall not constitute a waiver of,
any rights the Borrower might have or might acquire as a result of the payment
by the Fronting Bank of any draft or the reimbursement by the Borrower thereof):
(i) any lack of validity or enforceability of any Letter of Credit; (ii) the
existence of any claim, setoff, defense or other right which the Borrower or any
Guarantor may have at any time against a beneficiary of any Letter of Credit or
against any of the Lenders, whether in connection with this Agreement, the
transactions contemplated herein or any unrelated transaction; (iii) any draft,
demand, certificate or other document presented under any 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; (iv) payment by a
Fronting Bank of any Letter of Credit against presentation of a demand, draft or
certificate or other document which does not comply with the terms of such
Letter of Credit; (v) any other circumstance or happening whatsoever, which is

                                       29

<PAGE>

similar to any of the foregoing; or (vi) the fact that any Event of Default
shall have occurred and be continuing.

     SECTION 2.06.  Making of Loans.

          (a)  Except as contemplated by Section 2.11, Loans shall be either
ABR Loans or Eurodollar Loans as the Borrower may request subject to and in
accordance with this Section, provided that all Loans made pursuant to the same
Borrowing shall, unless otherwise specifically provided herein, be Loans of the
same Type. Each Lender may fulfill its Commitment with respect to any Eurodollar
Loan or ABR Loan by causing any lending office of such Lender to make such Loan;
provided that any such use of a lending office shall not affect the obligation
of the Borrower to repay such Loan in accordance with the terms of this
Agreement. Each Lender shall, subject to its overall policy considerations, use
reasonable efforts (but shall not be obligated) to select a lending office which
will not result in the payment of increased costs by the Borrower pursuant to
Section 2.15 or Section 2.18. Subject to the other provisions of this Section
and the provisions of Section 2.12, Borrowings of Loans of more than one Type
may be incurred at the same time, provided that no more than six (6) Borrowings
of Eurodollar Loans may be outstanding at any time.

          (b)  The Borrower shall give the Agent prior notice of each Borrowing
hereunder of at least three Business Days for Eurodollar Loans and one Business
Day for ABR Loans; such notice shall be irrevocable and shall specify the amount
of the proposed Borrowing (which shall not be less than $1,000,000 in the case
of Eurodollar Loans and $1,000,000 in the case of ABR Loans) and the date
thereof (which shall be a Business Day) and shall contain disbursement
instructions. Such notice, to be effective, must be received by the Agent not
later than 1:00 p.m., New York City time, on the third Business Day in the case
of Eurodollar Loans and 12:00 noon, New York City time on the first Business Day
in the case of ABR Loans, preceding the date on which such Borrowing is to be
made, provided that same day borrowings of ABR Loans in an aggregate amount of
$1,000,000 will be available if notice is received by the agent no later than
11:00 a.m., New York City time, on such day. With respect to Borrowings other
than same day Borrowings, such notice shall specify whether the Borrowing then
being requested is to be a Borrowing of ABR Loans or Eurodollar Loans. If no
election is made as to the Type of Loan, such notice shall be deemed a request
for Borrowing of ABR Loans. The Agent shall promptly notify each Lender of its
proportionate share of such Borrowing, the date of such Borrowing, the Type of
Borrowing or Loans being requested and the Interest Period or Interest Periods
applicable thereto, as appropriate. On the borrowing date specified in such
notice, each Lender shall make its share of the Borrowing available at the
office of the Agent at 270 Park Avenue, New York, New York 10017, no later than
12:00 noon, New York City time, in immediately available funds. Upon receipt of
the funds made available by the Lenders to fund any borrowing hereunder, the
Agent shall disburse such funds in the manner specified in the notice of
borrowing delivered by the Borrower and shall use reasonable efforts to make the
funds so received from the Lenders available to the Borrower no later than 2:00
p.m. New York City time.

     SECTION 2.07.  Repayment of Loans; Evidence of Debt.

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

          (c)  The Agent, as agent of the Borrower, shall maintain the Register
pursuant to Section 11.03(d), and subaccounts therein in which it shall record
(i) the amount of each Loan made hereunder, the Type thereof and the Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder,
(iii) the amount of any sum received by the Agent hereunder for the account of
the Lenders and each Lender's share thereof, (iv) the Letter of Credit
Outstandings (including, specifying all amounts drawn under Letters of Credit
and not then reimbursed) with respect to the Fronting Bank, (v) all
participations in Letters of Credit, (vi) the amount of any principal or
interest due and payable (or to become due and payable) and paid with respect to
drawn Letters of Credit and participations in drawn Letters of Credit, including
amounts described in Section 2.03 owing and paid to the Fronting Bank and
Lenders from time to time with respect to such drawn Letters of Credit.

          (d)  The entries made in the Register shall be prima facie evidence of
the existence and amounts of the obligations recorded therein; provided that the
failure of the Agent to maintain the Register or any error therein shall not in
any manner affect the obligation of the Borrower to repay the Loans in
accordance with the terms of this Agreement.

          (e)  Any Lender may request that Loans made by it be evidenced by a
promissory note. In such event, the Borrower shall execute and deliver to such
Lender a promissory note payable to the order of such Lender and its registered
assigns in a form furnished by the Agent and reasonably acceptable to the
Borrower. Thereafter, the Loans evidenced by such promissory note and interest
thereon shall at all times (including after assignment pursuant to Section
11.03) be represented by one or more promissory notes in such form payable to
the order of the payee named therein and its registered assigns.

     SECTION 2.08.  Interest on Loans.

          (a)  Subject to the provisions of Section 2.09, each ABR Loan shall
bear interest (computed on the basis of the actual number of days elapsed over a
year of 360 days or, when the Alternate Base Rate is based on the Prime Rate, a
year with 365 days or 366 days in a leap year) at a rate per annum equal to the
Alternate Base Rate plus the Applicable Margin.

          (b)  Subject to the provisions of Section 2.09, each Eurodollar Loan
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at a rate per annum equal, during each Interest Period
applicable thereto, to the Adjusted LIBOR Rate for such Interest Period in
effect for such Borrowing plus Applicable Margin.

                                       31

<PAGE>

          (c)  Accrued interest on all Loans shall be payable monthly in
arrears on each Interest Payment Date applicable thereto, on the Termination
Date, after the Termination Date on demand and (with respect to Eurodollar
Loans) upon any repayment or prepayment thereof (on the amount prepaid).

     SECTION 2.09.  Default Interest. If the Borrower or any Guarantor, as the
case may be, shall default in the payment of the principal of or interest on any
Loan or in the payment of any other amount becoming due hereunder (including,
without limitation, the reimbursement pursuant to Section 2.03(d) of any draft
drawn under a Letter of Credit), whether at stated maturity, by acceleration or
otherwise, the Borrower or such Guarantor, as the case may be, shall on demand
from time to time pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 360 days or when the Alternate Base
Rate is applicable and is based on the Prime Rate, a year with 365 days or 366
days in a leap year) equal to (x) in the case of Loans, the rate that would
otherwise be applicable thereto, plus 2.00% and (y) in the case of all other
amounts, the rate applicable to ABR Loans, plus 2.00%.

     SECTION 2.10.  Optional Termination or Reduction of Commitment. Upon at
least two Business Days' prior written notice to the Agent, the Borrower may at
any time in whole permanently terminate, or from time to time in part
permanently reduce, the Total Commitment; provided, however, that (i) no such
termination or reduction of the Total Commitment shall be permitted if, after
giving effect thereto and to any prepayments of the Loans in connection with
such termination or reduction, the outstanding aggregate principal amount of the
Loans plus the aggregate Letter of Credit Outstandings shall exceed the least of
(A) the Total Commitment then in effect, (B) the Borrowing Base and (C) the
Maximum Outstanding Amount and (ii) no such termination in whole shall be
permitted unless all Loans shall have been paid in full and no Letters of Credit
shall be outstanding, or, if outstanding, then backed by Cash Collateralization.
Each such reduction of the Total Commitment shall be in the principal amount of
$1,000,000 or any integral multiple thereof. Simultaneously with each reduction
or termination of the Total Commitment, the Borrower shall pay to the Agent for
the account of each Lender the Commitment Fee accrued and unpaid on the amount
of the Commitment of such Lender so terminated or reduced through the date
thereof. Any reduction of the Total Commitment pursuant to this Section shall be
applied to reduce the Commitment of each Lender according to each such Lender's
Commitment Percentage.

     SECTION 2.11.  Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Loan, the Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower absent manifest
error) that reasonable means do not exist for ascertaining the applicable
Adjusted LIBOR Rate, the Agent shall, as soon as practicable thereafter, give
written, facsimile or telegraphic notice of such determination to the Borrower
and the Lenders, and any request by the Borrower for a Borrowing of Eurodollar
Loans (including pursuant to a refinancing with Eurodollar Loans) pursuant to
Section 2.06 or 2.12 shall be deemed a request for a Borrowing of ABR Loans.
After such notice shall have been given and until the circumstances giving rise
to such notice no longer exist, each request for a Borrowing of Eurodollar Loans
shall be deemed to be a request for a Borrowing of ABR Loans.

                                       32

<PAGE>

     SECTION 2.12.  Refinancing of Loans. The Borrower shall have the right, at
any time, on three Business Days' prior irrevocable notice to the Agent (which
notice, to be effective, must be received by the Agent not later than 1:00 p.m.,
New York City time, on the third Business Day preceding the date of any
refinancing), (x) to refinance (without the satisfaction of the conditions set
forth in Section 4 as a condition to such refinancing) any outstanding Borrowing
or Borrowings of Loans of one Type (or a portion thereof) with a Borrowing of
Loans of the other Type or (y) to continue an outstanding Borrowing of
Eurodollar Loans for an additional Interest Period, subject to the following:

          (a)  as a condition to the refinancing of ABR Loans with Eurodollar
Loans and to the continuation of Eurodollar Loans for an additional Interest
Period, no Event of Default shall have occurred and be continuing at the time of
such refinancing;

          (b)  if less than a full Borrowing of Loans shall be refinanced, such
refinancing shall be made pro rata among the Lenders in accordance with the
respective principal amounts of the Loans comprising such Borrowing held by the
Lenders immediately prior to such refinancing;

          (c)  the aggregate principal amount of Loans being refinanced shall
be at least $1,000,000, provided that no partial refinancing of a Borrowing of
Eurodollar Loans shall result in the Eurodollar Loans remaining outstanding
pursuant to such Borrowing being less than $1,000,000 in aggregate principal
amount;

          (d)  each Lender shall effect each refinancing by applying the
proceeds of its new Eurodollar Loan or ABR Loan, as the case may be, to its Loan
being refinanced;

          (e)  the Interest Period with respect to a Borrowing of Eurodollar
Loans effected by a refinancing or in respect to the Borrowing of Eurodollar
Loans being continued as Eurodollar Loans shall commence on the date of
refinancing or the expiration of the current Interest Period applicable to such
continuing Borrowing, as the case may be; and

          (f)  a Borrowing of Eurodollar Loans may be refinanced only on the
last day of an Interest Period applicable thereto.

In the event that the Borrower shall not give notice to refinance any Borrowing
of Eurodollar Loans, or to continue such Borrowing as Eurodollar Loans, or shall
not be entitled to refinance or continue such Borrowing as Eurodollar Loans, in
each case as provided above, such Borrowing shall automatically be refinanced
with a Borrowing of ABR Loans at the expiration of the then-current Interest
Period. The Agent shall, after it receives notice from the Borrower, promptly
give each Lender notice of any refinancing, in whole or part, of any Loan made
by such Lender.

     SECTION 2.13.  Mandatory Prepayment; Commitment Termination; Cash
Collateral.

          (a)  If at any time the aggregate principal amount of the outstanding
Loans plus the Letter of Credit Outstandings exceeds the least of (x) the Total
Commitment, (y) the Borrowing Base and (z) the Maximum Outstanding Amount, the
Borrower will within three Business Days (i) prepay the Loans in an amount
necessary to cause the aggregate principal

                                       33

<PAGE>

amount of the outstanding Loans plus the aggregate Letter of Credit Outstandings
to be equal to or less than the Total Commitment, the Borrowing Base and/or the
Maximum Outstanding Amount, as the case may be, and (ii) if, after giving effect
to the prepayment in full of the Loans, the undrawn amount of outstanding Letter
of Credit Outstandings in excess of the amount of cash held in the Letter of
Credit Account exceeds the Total Commitment, the Borrowing Base and/or the
Maximum Outstanding Amount, as the case may be, deposit into the Letter of
Credit Account an amount equal to 105% of the amount by which the aggregate
Letter of Credit Outstandings in excess of the amount of cash held in the Letter
of Credit Account so exceeds the Total Commitment, the Borrowing Base or the
Maximum Outstanding Amount, as the case may be.

          (b)  Upon the Termination Date, the Total Commitment shall be
terminated in full and the Borrower shall pay the Loans in full (plus any
accrued but unpaid interest and fees thereon) and, except as the Agent may
otherwise agree in writing, if any Letter of Credit remains outstanding, shall
comply with Section 2.03(b).

     SECTION 2.14.  Optional Prepayment of Loans; Reimbursement of Lenders.

          (a)  The Borrower shall have the right at any time and from time to
time to prepay any Loans, in whole or in part, (x) with respect to Eurodollar
Loans, upon at least three Business Days' prior written or facsimile notice to
the Agent and (y) with respect to ABR Loans on the same Business Day if written
or facsimile notice is received by the Agent prior to 12:00 noon, New York City
time, and thereafter upon at least one Business Day's prior written or facsimile
notice to the Agent; provided, however, that (i) each such partial prepayment
shall be in multiples of $1,000,000, (ii) no prepayment of Eurodollar Loans
shall be permitted pursuant to this Section 2.14(a) other than on the last day
of an Interest Period applicable thereto unless such prepayment is accompanied
by the payment of the amounts described in clause (i) of the first sentence of
Section 2.14(b), and (iii) no partial prepayment of a Borrowing of Eurodollar
Loans shall result in the aggregate principal amount of the Eurodollar Loans
remaining outstanding pursuant to such Borrowing being less than $1,000,000.
Each notice of prepayment shall specify the prepayment date, the principal
amount of the Loans to be prepaid and in the case of Eurodollar Loans, the
Borrowing or Borrowings pursuant to which made, shall be irrevocable and shall
commit the Borrower to prepay such Loan by the amount and on the date stated
therein. The Agent shall, promptly after receiving notice from the Borrower
hereunder, notify each Lender of the principal amount of the Loans held by such
Lender which are to be prepaid, the prepayment date and the manner of
application of the prepayment.

          (b)  The Borrower shall reimburse each Lender on demand for any loss
incurred or to be incurred by it in the reemployment of the funds released (i)
resulting from any prepayment (for any reason whatsoever, including, without
limitation, refinancing with ABR Loans) of any Eurodollar Loan required or
permitted under this Agreement, if such Loan is prepaid other than on the last
day of the Interest Period for such Loan (including, without limitation, any
such prepayment in connection with the syndication of the credit facility
evidenced by this Agreement) or (ii) in the event that after the Borrower
delivers a notice of borrowing under Section 2.06 in respect of Eurodollar
Loans, such Loans are not made on the first day of the Interest Period specified
in such notice of borrowing for any reason other than a breach by such Lender of
its obligations hereunder. Such loss shall be the amount as reasonably

                                       34

<PAGE>

determined by such Lender as the excess, if any, of (A) the amount of interest
which would have accrued to such Lender on the amount so paid or not borrowed at
a rate of interest equal to the Adjusted LIBOR Rate for such Loan, for the
period from the date of such payment or failure to borrow to the last day (x) in
the case of a payment or refinancing with ABR Loans other than on the last day
of the Interest Period for such Loan, of the then current Interest Period for
such Loan, or (y) in the case of such failure to borrow, of the Interest Period
for such Loan which would have commenced on the date of such failure to borrow,
over (B) the amount of interest which would have accrued to such Lender on such
amount by placing such amount on deposit for a comparable period with leading
banks in the London interbank market. Each Lender shall deliver to the Borrower
from time to time one or more certificates setting forth the amount of such loss
as determined by such Lender.

          (c)  In the event the Borrower fails to prepay any Loan on the date
specified in any prepayment notice delivered pursuant to Section 2.14(a), the
Borrower on demand by any Lender shall pay to the Agent for the account of such
Lender any amounts required to compensate such Lender for any loss incurred by
such Lender as a result of such failure to prepay, including, without
limitation, any loss, cost or expenses incurred by reason of the acquisition of
deposits or other funds by such Lender to fulfill deposit obligations incurred
in anticipation of such prepayment, but without duplication of any amounts paid
under Section 2.14(b). Each Lender shall deliver to the Borrower from time to
time one or more certificates setting forth the amount of such loss as
determined by such Lender.

          (d)  Except as otherwise provided herein, any partial prepayment of
the Loans by the Borrower pursuant to Sections 2.13 or 2.14 shall be applied as
specified by the Borrower or, in the absence of such specification, as
determined by the Agent, provided that in the latter case no Eurodollar Loans
shall be prepaid pursuant to Section 2.13 to the extent that such Loan has an
Interest Period ending after the required date of prepayment unless and until
all outstanding ABR Loans and Eurodollar Loans with Interest Periods ending on
such date have been repaid in full.

     SECTION 2.15.  Reserve Requirements; Change in Circumstances.

          (a)  Notwithstanding any other provision herein, if after the date of
this Agreement any change in applicable law or regulation or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to any Lender of
the principal of or interest on any Eurodollar Loan made by such Lender or any
fees or other amounts payable hereunder (other than Indemnified Taxes or Other
Taxes covered by Section 2.18 and changes with respect to taxes imposed on or
measured by the overall net income of such Lender), or shall impose, modify or
deem applicable any reserve, special deposit or similar requirement against
assets of, deposits with or for the account of or credit extended by such Lender
(except any such reserve requirement which is reflected in the Adjusted LIBOR
Rate) or shall impose on such Lender or the London interbank market any other
condition affecting this Agreement or the Eurodollar Loans made by such Lender,
and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan or to reduce the amount of
any sum received or receivable by such Lender hereunder (whether of principal,
interest or otherwise) by an amount deemed by such Lender to be material, then
the Borrower will pay to such Lender in accordance with paragraph (c) below

                                       35

<PAGE>

such additional amount or amounts as will compensate such Lender for such
additional costs incurred or reduction suffered.

          (b)  If any Lender shall have determined that the adoption or
effectiveness after the date hereof of any law, rule, regulation or guideline
regarding capital adequacy, or any change in any of the foregoing or in the
interpretation or administration of any of the foregoing by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any lending office of
such Lender) or any Lender's holding company with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on such Lender's capital or on the capital of such
Lender's holding company, if any, as a consequence of this Agreement, the Loans
made by such Lender pursuant hereto, such Lender's Commitment hereunder or the
issuance of, or participation in, any Letter of Credit by such Lender to a level
below that which such Lender or such Lender's holding company could have
achieved but for such adoption, change or compliance (taking into account
Lender's policies and the policies of such Lender's holding company with respect
to capital adequacy) by an amount deemed by such Lender to be material (except
to the extent that such amount is reflected in the Adjusted LIBOR Rate), then
from time to time the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such Lender's holding company for
any such reduction suffered.

          (c)  A certificate of each Lender setting forth such amount or
amounts as shall be necessary to compensate such Lender or its holding company
as specified in paragraph (a) or (b) above, as the case may be, shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay each Lender the amount shown as due on any such certificate
delivered to it within 10 days after its receipt of the same. Any Lender
receiving any such payment shall promptly make a refund thereof to the Borrower
if the law, regulation, guideline or change in circumstances giving rise to such
payment is subsequently deemed or held to be invalid or inapplicable.

          (d)  Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's right to demand compensation with respect to such period or any
other period, provided that the Borrower shall not be required to compensate a
Lender pursuant to this Section for any increased costs or reductions incurred
more than 270 days prior to the date that such Lender notifies the Borrower of
the circumstance giving rise to such increased costs or reductions and of such
Lender's intention to claim compensation therefor. The protection of this
Section shall be available to each Lender regardless of any possible contention
of the invalidity or inapplicability of the law, rule, regulation, guideline or
other change or condition which shall have occurred or been imposed.

     SECTION 2.16.  Change in Legality.

          (a)  Notwithstanding anything to the contrary contained elsewhere in
this Agreement, if (x) any change after the date of this Agreement in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration thereof

                                       36

<PAGE>

shall make it unlawful for a Lender to make or maintain a Eurodollar Loan or to
give effect to its obligations as contemplated hereby with respect to a
Eurodollar Loan or (y) at any time any Lender determines that the making or
continuance of any of its Eurodollar Loans has become impracticable as a result
of a contingency occurring after the date hereof which adversely affects the
London interbank market or the position of such Lender in such market, then, by
written notice to the Borrower, such Lender may (i) declare that Eurodollar
Loans will not thereafter be made by such Lender hereunder, whereupon any
request by the Borrower for a Eurodollar Borrowing shall, as to such Lender
only, be deemed a request for an ABR Loan unless such declaration shall be
subsequently withdrawn; and (ii) require that all outstanding Eurodollar Loans
made by it be converted to ABR Loans, in which event all such Eurodollar Loans
shall be automatically converted to ABR Loans as of the effective date of such
notice as provided in paragraph (b) below. In the event any Lender shall
exercise its rights under clause (i) or (ii) of this paragraph (a), all payments
and prepayments of principal which would otherwise have been applied to repay
the Eurodollar Loans that would have been made by such Lender or the converted
Eurodollar Loans of such Lender shall instead be applied to repay the ABR Loans
made by such Lender in lieu of, or resulting from the conversion of, such
Eurodollar Loans.

          (b)  For purposes of this Section 2.16, a notice to the Borrower by
any Lender pursuant to paragraph (a) above shall be effective, if lawful, and if
any Eurodollar Loans shall then be outstanding, on the last day of the
then-current Interest Period, otherwise, such notice shall be effective on the
date of receipt by the Borrower.

     SECTION 2.17.  Pro Rata Treatment, etc. All payments and repayments of
principal and interest in respect of the Loans (except as provided in Sections
2.15 and 2.16) shall be made pro rata among the Lenders in accordance with the
then outstanding principal amount of the Loans and/or participations in Letter
of Credit Outstandings hereunder and all payments of Commitment Fees and Letter
of Credit Fees (other than those payable to a Fronting Bank) shall be made among
the Lenders in accordance with their Commitment Percentages. All payments by the
Borrower hereunder shall be (i) net of any tax applicable to the Borrower or
Guarantor and (ii) made in Dollars in immediately available funds at the office
of the Agent by 12:00 noon, New York City time, on the date on which such
payment shall be due. Interest in respect of any Loan hereunder shall accrue
from and including the date of such Loan to but excluding the date on which such
Loan is paid in full or converted to a Loan of a different Type.

     SECTION 2.18.  Taxes.

          (a)  Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of, and without deduction for,
any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(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) the Agent, Lender or Fronting Bank (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

                                       37

<PAGE>

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

          (c)  The Borrower will indemnify the Agent, each Lender and the
Fronting Bank, within 10 days after written demand therefore, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Agent, such Lender or
the Fronting Bank, as the case may be, on or with respect to any payment by or
on account of any obligation of the Borrower hereunder (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable
under this Section) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Borrower by a Lender or the Fronting Bank, or by the
Agent on its own behalf or on behalf of a Lender or the Fronting Bank, shall be
conclusive absent manifest error.

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Agent the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of the return
reporting such payment or other evidence of such payment reasonably satisfactory
to the Agent.

          (e)  Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower or the Agent as will permit such payments
to be made without withholding or at a reduced rate

          (f)  Each U.S. Lender shall deliver to the Borrower (with a copy to
the Agent) at the time or times prescribed by applicable law, a properly
completed and executed Internal Revenue Service Form W-9 (certifying that such
U.S. Lender is entitled to an exemption from United States backup withholding
tax) or any successor form. Solely for purposes of this Section 2.18(f), a U.S.
Lender shall not include a Lender, Fronting Bank, Agent or any other recipient
of any payment to be made by or on account of any obligation of the Borrower
hereunder that may be treated as an exempt recipient based on the indicators
described in Treasury Regulation Section 1.6049-4(c)(1)(ii).

     SECTION 2.19.  Certain Fees. The Borrower shall pay to the Agent, for the
respective accounts of the Agent and the Lenders, the fees set forth in that
certain fee letter dated May 5, 2003, among J.P. Morgan Securities Inc., the
Initial Lenders and the Borrower at the times set forth therein.

     SECTION 2.20.  Commitment Fee. The Borrower shall pay to the Lenders a
commitment fee (the "Commitment Fee") for the period commencing on the Closing
Date to the Termination Date or the earlier date of termination of the
Commitment, computed (on the basis of the actual number of days elapsed over a
year of 360 days) at the rate of 1.00% per annum on

                                       38

<PAGE>

the average daily Unused Total Commitment. Such Commitment Fee, to the extent
then accrued, shall be payable (i) monthly, in arrears, on the last calendar day
of each month, (ii) on the Termination Date and (iii) as provided in Section
2.10 hereof, upon any reduction or termination in whole or in part of the Total
Commitment.

     SECTION 2.21.  Letter of Credit Fees. The Borrower shall pay with respect
to each Letter of Credit (i) to the Agent on behalf of the Lenders a fee
calculated (on the basis of the actual number of days elapsed over a year of 360
days) at the rate equal to the Applicable Margin applicable to Eurodollar Loans
on the daily average Letter of Credit Outstandings and (ii) to the Fronting Bank
such Fronting Bank's customary fees for issuance, amendments and processing
referred to in Section 2.03. In addition, the Borrower agrees to pay each
Fronting Bank for its account a fronting fee of 1.00% per annum in respect of
each Letter of Credit issued by such Fronting Bank, for the period from and
including the date of issuance of such Letter of Credit to and including the
date of termination of such Letter of Credit, computed at a rate, and payable at
times, to be determined by such Fronting Bank, the Borrower and the Agent.
Accrued fees described in clause (i) of the first sentence of this paragraph in
respect of each Letter of Credit shall be due and payable monthly in arrears on
the last calendar day of each month and on the Termination Date. Accrued fees
described in clause (ii) of the first sentence of this paragraph in respect of
each Letter of Credit shall be payable at times to be determined by the Fronting
Bank, the Borrower and the Agent.

     SECTION 2.22.  Nature of Fees. All Fees shall be paid on the dates due, in
immediately available funds, to the Agent for the respective accounts of the
Agent and the Lenders, as provided herein and in the fee letter described in
Section 2.19. Once paid, none of the Fees shall be refundable under any
circumstances.

     SECTION 2.23.  Priority and Liens.

          (a)  The Borrower and each of the Guarantors hereby covenants,
represents and warrants hereby that, upon entry of the Interim Order (and the
Final Order, as applicable), the Obligations of the Borrower and the Guarantors
hereunder and under the other Loan Documents and the Interim Order (and the
Final Order, as applicable), including, without limitation in respect of Cash

Code, shall at all times constitute allowed Superpriority Claims, (ii) pursuant
to Section 364(c)(2) of the Bankruptcy Code, shall at all times be secured by a
perfected first priority Lien on all Collateral, including without limitation,
all cash maintained in the Letter of Credit Account, the Concentration Account,

investments of the funds contained therein, that is otherwise not encumbered by
a valid and perfected Lien as of the Petition Date, including the proceeds of
all avoidance actions, (iii) pursuant to Section 364(c)(3) of the Bankruptcy

Liens perfected (but not granted) thereafter to the extent such post-Filing Date
perfection in respect of a pre-Filing Date claim is expressly permitted under
the Bankruptcy Code, and (iv) pursuant to Section 364(d)(1) of the Bankruptcy
Code, shall be secured by a perfected first priority priming Lien upon all
Collateral (x) that is subject to a valid Lien or security interest in effect on
the Filing Date to secure the Pre-Petition Obligations, (y) that is

                                       39

the Prepetition Obligations, subject and subordinate in each case with respect
to subclauses (i) through (iv) above, only to payment of (A) the unpaid fees of
the clerk of the Bankruptcy Court and of the United States Trustee pursuant to
28 U.S.C. Section 1930(a) and (b), (B) following the occurrence and during the
continuation of a Default or Event of Default, the aggregate allowed unpaid fees
and expenses payable under Sections 330 and 331 of the Bankruptcy Code to

Pre-Petition Agent or the Existing Lenders under the Loan Documents, the
Existing Agreement or the Interim Order (and the Final Order, as applicable), in

(ii) and (iii) above, and (iii) cash in the Letter of Credit Account, shall not
be subject to the Carve-Out. Notwithstanding anything herein to the contrary,
the Carve-Out shall not be used to commence or prosecute (but may be used to
investigate) any Prohibited Claim.

          (b)  As to all Collateral, including without limitation, all cash,
cash equivalents, commercial tort claims and real property the title to which is
held by the Borrower or any Guarantor, or the possession of which is held by the

Borrower and each Guarantor hereby assigns and conveys as security, grants a
security interest in, hypothecates, mortgages, pledges and sets over unto the
Agent (on behalf of the Lenders) all of the right, title and interest of the
Borrower and such

                                       40

cash equivalents, commercial tort claims and owned real property and in all such
leasehold interests, together in each case with all of the right, title and
interest of the Borrower and such Guarantor in and to all buildings,

each Guarantor acknowledges that, pursuant to the Interim Order (and the Final
Order, as applicable), the Liens granted in favor of the Agent (on behalf of the
Lenders) in all of the Collateral shall be perfected without the recordation of
any Uniform Commercial Code financing statements, notices of Lien or other
instruments of mortgage or assignment. The Borrower and each Guarantor further
agrees that (i) the Agent shall have the rights and remedies set forth in
Section 10 in respect of the Collateral, (ii) if requested by the Agent, the
Borrower and each of the Guarantors shall enter into separate security
agreements, pledge agreements and fee and leasehold mortgages with respect to
such Collateral on terms reasonably satisfactory to the Agent and (iii) the
Agent is authorized to file or record financing statements and other filing or
recordation documents or instruments with respect to the Collateral without the
signature of the Borrower or any Guarantor in such form and in such offices as
the Agent reasonably determines appropriate to further evidence the perfection
of the security interests of the Agent under this Agreement and to use the
collateral description "all personal property" in any such financing statements.

          (c)  The Borrower and each Guarantor acknowledge and agree that the
Existing Lenders shall receive (i) as adequate protection for, and to the extent
of, any diminution in the value of the Existing Lenders' respective interests in
their collateral whether resulting from the imposition of the automatic stay,

Order, as applicable) and (ii) as further adequate protection (A) the payment on
a current basis of the reasonable fees and expenses (including, but not limited
to, the reasonable fees and disbursements of counsel and internal and
third-party consultants, including financial consultants, appraisers and
auditors) incurred by the Pre-Petition Agent under the Existing Agreement
(including, without limitation, on-going administration fees and expenses and
any unpaid prepetition fees and expenses), (B) subject to the consent of the
Lenders and the Pre-Petition Agent, the right to apply Eligible Cash in excess
of $30,000,000 to the repayment of amounts owing under the Existing Agreement,
and (C) receipt of all financial statements and other reports furnished to the
Agent or the Lenders pursuant hereto. None of such fees, costs and charges shall
be subject to the approval of the Bankruptcy Court and no recipient of any such
payment shall be required to file with respect thereto any interim or final fee
application with the Bankruptcy Court. Notwithstanding the foregoing, the grant
of adequate protection pursuant to the Interim Order (and the Final Order, as
applicable) is without prejudice to the right of the Existing Lenders to seek
modification of the grant of adequate protection provided by the Interim Order
(and the Final Order, as applicable) so as to provide different or additional
adequate protection. So long as there are any borrowings or Letters of Credit
outstanding or the Commitment is in effect, the Existing Lenders shall not be

                                       41

enforcement of such adequate protection liens or the liens granted pursuant to
the Existing Agreement.

upon the occurrence and during the continuance of any Event of Default, the
Agent and each Lender is hereby authorized at any time and from time to time, to
the fullest extent permitted by law and without further order of or application

special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Agent and each such Lender to or for the
credit or the account of the Borrower or any Guarantor against any and all of
the obligations of such Borrower or Guarantor now or hereafter existing under
the Loan Documents, irrespective of whether or not such Lender shall have made
any demand under any Loan Document and although such obligations may not have
been accelerated. Each Lender and the Agent agrees promptly to notify the
Borrower and Guarantors after any such set-off and application made by such
Lender or by the Agent, as the case may be, provided that the failure to give
such notice shall not affect the validity of such set-off and application. The
rights of each Lender and the Agent under this Section are in addition to other
rights and remedies which such Lender and the Agent may have upon the occurrence
and during the continuance of any Event of Default.

     SECTION 2.25.  Security Interest in Letter of Credit Account. Pursuant to

Lenders) a first priority security interest, senior to all other Liens, if any,
in all of the Borrower and the Guarantors' right, title and interest in and to
the Letter of Credit Account, the Concentration Account and any direct
investment of funds contained therein and any direct investment of the funds
contained therein and the Asset Sale Proceeds Account and any direct investment

Borrower and the Guarantors, the Lenders shall be entitled to immediate payment
of such Obligations without further application to or order of the Bankruptcy
Court.

     SECTION 2.27.  No Discharge; Survival of Claims. Each of the Borrower and
the Guarantors agrees that (i) its obligations hereunder shall not be discharged

Code, hereby waives any such discharge) and (ii) the Superpriority Claim granted

the case may be, enforceable against the Borrower and the Guarantors, as the
case may be, in accordance with its terms and the Orders.

     SECTION 3.03.  Statements Made. The information that has been delivered in
writing by the Borrower or any of the Guarantors to the Agent or to the
Bankruptcy Court in connection with any Loan Document, and any financial

the circumstances in which made, contains no untrue statement of a material fact
and does not omit to state a material fact necessary to make such statements not

business, properties, assets, prospects or condition (financial or otherwise) of

reasonable and customary fees and expenses of any such employee or
representative retained by the Agent to conduct any such evaluation or
appraisal, including fees and out-of-pocket expenses associated with the Agent's

SECTION 8  THE AGENT

     SECTION 8.01.  Administration by Agent. The general administration of the
Loan Documents shall be by the Agent. Each Lender hereby irrevocably authorizes
the Agent, at its discretion, to take or refrain from taking such actions as
agent on its behalf and to exercise or refrain from exercising such powers under
the Loan Documents as are delegated by the terms hereof or thereof, as
appropriate, together with all powers reasonably incidental thereto (including
the release of Collateral in connection with any transaction that is expressly
permitted by the Loan Documents). The Agent shall have no duties or
responsibilities except as set forth in this Agreement and the remaining Loan
Documents.

     SECTION 8.02.  Advances and Payments.

          (a)  On the date of each Loan, the Agent shall be authorized (but not
obligated) to advance, for the account of each of the Lenders, the amount of the
Loan to be made by it in accordance with its Commitment hereunder. Should the
Agent do so, each of the Lenders agrees forthwith to reimburse the Agent in
immediately available funds for the amount so advanced on its behalf by the
Agent, together with interest at the Federal Funds Effective Rate if not so

                                       63

<PAGE>

reimbursed on the date due from and including such date but not including the
date of reimbursement.

          (b)  Any amounts received by the Agent in connection with this
Agreement (other than amounts to which the Agent is entitled pursuant to
Sections 2.19, 8.06, 11.05 and 11.06), the application of which is not otherwise
provided for in this Agreement (including pursuant to Section 10.03) shall be
applied, first, in accordance with each Lender's Commitment Percentage to pay
accrued but unpaid Commitment Fees or Letter of Credit Fees, and second, in
accordance with each Lender's Commitment Percentage to pay accrued but unpaid
interest and the principal balance outstanding and all unreimbursed Letter of
Credit drawings. All amounts to be paid to a Lender by the Agent shall be
credited to that Lender, after collection by the Agent, in immediately available
funds either by wire transfer or deposit in that Lender's correspondent account
with the Agent, as such Lender and the Agent shall from time to time agree.

     SECTION 8.03.  Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower, including, but not limited to, a secured claim under Section 506
of the Bankruptcy Code or other security or interest arising from, or in lieu
of, such secured claim and received by such Lender under any applicable
bankruptcy, insolvency or other similar law, or otherwise, obtain payment in
respect of its Loans as a result of which the unpaid portion of its Loans is
proportionately less than the unpaid portion of the Loans of any other Lender
(a) it shall promptly purchase at par (and shall be deemed to have thereupon
purchased) from such other Lender a participation in the Loans of such other
Lender, so that the aggregate unpaid principal amount of each Lender's Loans and
its participation in Loans of the other Lenders shall be in the same proportion
to the aggregate unpaid principal amount of all Loans then outstanding as the
principal amount of its Loans prior to the obtaining of such payment was to the
principal amount of all Loans outstanding prior to the obtaining of such payment
and (b) such other adjustments shall be made from time to time as shall be
equitable to ensure that the Lenders share such payment pro-rata, provided that
if any such non-pro-rata payment is thereafter recovered or otherwise set aside
such purchase of participations shall be rescinded (without interest). The
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding (or deemed to be holding) a participation in a Loan may exercise
any and all rights of banker's lien, setoff (in each case, subject to the same
notice requirements as pertain to clause (iv) of the remedial provisions of
Section 7.01) or counterclaim with respect to any and all moneys owing by the
Borrower to such Lender as fully as if such Lender held a Note and was the
original obligee thereon, in the amount of such participation.

     SECTION 8.04.  Agreement of Required Lenders. Upon any occasion requiring
or permitting an approval, consent, waiver, election or other action on the part
of the Required Lenders, action shall be taken by the Agent for and on behalf or
for the benefit of all Lenders upon the direction of the Required Lenders, and
any such action shall be binding on all Lenders. No amendment, modification,
consent, or waiver shall be effective except in accordance with the provisions
of Section 11.10.

          (a)  The Agent when acting on behalf of the Lenders, may execute any
of its respective duties under this Agreement by or through any of its
respective officers, agents, and employees, and neither the Agent nor its
directors, officers, agents, employees or Affiliates shall be liable to the
Lenders or any of them for any action taken or omitted to be taken in good
faith, or be responsible to the Lenders or to any of them for the consequences
of any oversight or error of judgment, or for any loss, unless the same shall
happen through its gross negligence or willful misconduct. The Agent and its
respective directors, officers, agents, employees and Affiliates shall in no
event be liable to the Lenders or to any of them for any action taken or omitted
to be taken by them pursuant to instructions received by them from the Required
Lenders or in reliance upon the advice of counsel selected by it. Without
limiting the foregoing, neither the Agent, nor any of its respective directors,
officers, employees, agents or Affiliates shall be responsible to any Lender for
the due execution, validity, genuineness, effectiveness, sufficiency, or
enforceability of, or for any statement, warranty, or representation in, this
Agreement, any Loan Document or any related agreement, document or order, or
shall be required to ascertain or to make any inquiry concerning the performance
or observance by the Borrower of any of the terms, conditions, covenants, or
agreements of this Agreement or any of the Loan Documents.

          (b)  Neither the Agent nor any of its respective directors, officers,
employees, agents or Affiliates shall have any responsibility to the Borrower or
the Guarantors on account of the failure or delay in performance or breach by
any Lender or by the Borrower or the Guarantors of any of their respective
obligations under this Agreement or any of the Loan Documents or in connection
herewith or therewith.

          (c)  The Agent, in its capacity as Agent hereunder, shall be entitled

such person to be genuine or correct and to have been signed or sent by a person
or persons believed by such person to be the proper person or persons, and such
person shall be entitled to rely on advice of legal counsel, independent public
accountants, and other professional advisers and experts selected by such
person.

     SECTION 8.06.  Reimbursement and Indemnification. Each Lender agrees (i) to
reimburse (x) the Agent for such Lender's Commitment Percentage of any expenses
and fees incurred for the benefit of the Lenders under this Agreement and any of
the Loan Documents, including, without limitation, counsel fees and compensation
of agents and employees paid for services rendered on behalf of the Lenders, and
any other expense incurred in connection with the operations or enforcement
thereof not reimbursed by the Borrower or the Guarantors and (y) the Agent for
such Lender's Commitment Percentage of any expenses of the Agent incurred for
the benefit of the Lenders that the Borrower has agreed to reimburse pursuant to
Section 11.05 and has failed to so reimburse and (ii) to indemnify and hold
harmless the Agent and any of its directors, officers, employees, agents or
Affiliates, on demand, in the amount of its proportionate share, from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses, or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against it
or any of them in any way relating to or arising out of this Agreement or any of
the Loan Documents or any action taken or omitted by it or any of them under
this Agreement or any of the Loan Documents to the extent not reimbursed by the

                                       65

<PAGE>

Borrower or the Guarantors (except such as shall result from their respective
gross negligence or willful misconduct).

     SECTION 8.07.  Rights of Agent. It is understood and agreed that JPMorgan
Chase shall have the same rights and powers hereunder (including the right to
give such instructions) as the other Lenders and may exercise such rights and
powers, as well as its rights and powers under other agreements and instruments
to which it is or may be party, and engage in other transactions with the
Borrower or any Guarantor, as though it were not the Agent of the Lenders under
this Agreement.

     SECTION 8.08.  Independent Lenders. Each Lender acknowledges that it has
decided to enter into this Agreement and to make the Loans hereunder based on
its own analysis of the transactions contemplated hereby and of the
creditworthiness of the Borrower and the Guarantors and agrees that the Agent
shall bear no responsibility therefor.

     SECTION 8.09.  Notice of Transfer. The Agent may deem and treat a Lender
party to this Agreement as the owner of such Lender's portion of the Loans for
all purposes, unless and until a written notice of the assignment or transfer
thereof executed by such Lender shall have been received by the Agent.

     SECTION 8.10.  Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor
Agent, which shall be reasonably satisfactory to the Borrower. If no successor
Agent shall have been so appointed by the Required Lenders and shall have
accepted such appointment, within 30 days after the retiring Agent's giving of
notice of resignation, the retiring Agent may, on behalf of the Lenders, appoint
a successor Agent, which shall be a commercial bank organized under the laws of
the United States or of any State thereof and having a combined capital and
surplus of a least $100,000,000, which shall be reasonably satisfactory to the
Borrower. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations under
this Agreement. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 8 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement.

     SECTION 8.11.  Syndication Agent. The Syndication Agent shall have no
duties or responsibilities hereunder in its capacity as such.

SECTION 9  GUARANTY

     SECTION 9.01.  Guaranty.

          (a)  Each of the Guarantors unconditionally and irrevocably guarantees
the due and punctual payment by the Borrower of the Obligations. Each of the
Guarantors further agrees that the Obligations may be extended or renewed, in
whole or in part, without notice to or further

                                       66

<PAGE>

assent from it, and it will remain bound upon this guaranty notwithstanding any
extension or renewal of any of the Obligations. The Obligations of the
Guarantors shall be joint and several.

          (b)  Each of the Guarantors waives presentation to, demand for payment
from and protest to the Borrower or any other Guarantor, and also waives notice
of protest for nonpayment. The Obligations of the Guarantors hereunder shall not
be affected by (i) the failure of the Agent or a Lender to assert any claim or
demand or to enforce any right or remedy against the Borrower or any other
Guarantor under the provisions of this Agreement or any other Loan Document or
otherwise; (ii) any extension or renewal of any provision hereof or thereof;
(iii) any rescission, waiver, compromise, acceleration, amendment or
modification of any of the terms or provisions of any of the Loan Documents;
(iv) the release, exchange, waiver or foreclosure of any security held by the
Agent for the Obligations or any of them; (v) the failure of the Agent or a
Lender to exercise any right or remedy against any other Guarantor; or (vi) the
release or substitution of any Guarantor or any other Guarantor.

          (c)  Each of the Guarantors further agrees that this guaranty
constitutes a guaranty of payment when due and not just of collection, and
waives any right to require that any resort be had by the Agent or a Lender to
any security held for payment of the Obligations or to any balance of any
deposit, account or credit on the books of the Agent or a Lender in favor of the
Borrower or any other Guarantor, or to any other Person.

          (d)  Each of the Guarantors hereby waives any defense that it might
have based on a failure to remain informed of the financial condition of the
Borrower and of any other Guarantor and any circumstances affecting the ability
of the Borrower to perform under this Agreement.

          (e)  Each Guarantor's guaranty shall not be affected by the
genuineness, validity, regularity or enforceability of the Obligations or any
other instrument evidencing any Obligations, or by the existence, validity,
enforceability, perfection, or extent of any collateral therefor or by any other
circumstance relating to the Obligations which might otherwise constitute a
defense to this Guaranty. Neither of the Agent, nor any of the Lenders makes any
representation or warranty in respect to any such circumstances or shall have
any duty or responsibility whatsoever to any Guarantor in respect of the
management and maintenance of the Obligations.

          (f)  Subject to the provisions of Section 7.01, upon the Obligations
becoming due and payable (by acceleration or otherwise), the Lenders shall be
entitled to immediate payment of such Obligations by the Guarantors upon written
demand by the Agent, without further application to or order of the Bankruptcy
Court.

     SECTION 9.02.  No Impairment of Guaranty. The obligations of the Guarantors
hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including, without limitation, any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense or set-off, counterclaim, recoupment or termination whatsoever by reason
of the invalidity, illegality or unenforceability of the Obligations. Without
limiting the generality of the foregoing, the obligations of the Guarantors
hereunder shall not be discharged or impaired or otherwise affected by the
failure of the Agent or

                                       67

<PAGE>

a Lender to assert any claim or demand or to enforce any remedy under this
Agreement or any other agreement, by any waiver or modification of any provision
thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Obligations, or by any other act or thing or omission or
delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of the Guarantors or would otherwise operate as a discharge
of the Guarantors as a matter of law, unless and until the Obligations are paid
in full.

     SECTION 9.03.  Subrogation. Upon payment by any Guarantor of any sums to
the Agent or a Lender hereunder, all rights of such Guarantor against the
Borrower arising as a result thereof by way of right of subrogation or
otherwise, shall in all respects be subordinate and junior in right of payment
to the prior final and indefeasible payment in full of all the Obligations. If
any amount shall be paid to such Guarantor for the account of the Borrower, such
amount shall be held in trust for the benefit of the Agent and the Lenders and
shall forthwith be paid to the Agent and the Lenders to be credited and applied
to the Obligations, whether matured or unmatured.

SECTION 10 REMEDIES; APPLICATION OF PROCEEDS

     SECTION 10.01. Remedies; Obtaining the Collateral Upon Default. Upon the
occurrence and during the continuance of an Event of Default (and after notice
of such Event of Default, if required), to the extent any such action is not
inconsistent with the Orders or Section 7, the Agent, in addition to any rights
now or hereafter existing under applicable law, and without application to or
order of the Bankruptcy Court, shall have all rights as a secured creditor under
the Uniform Commercial Code in all relevant jurisdictions and may:

          (a)  personally, or by agents or attorneys, immediately retake
possession of the Collateral or any part thereof, from the Borrower, any
Guarantor or any other Person who then has possession of any part thereof with
or without notice or process of law (but subject to any requirement of
applicable law), and for that purpose may enter upon the Borrower's or any
Guarantor's premises where any of the Collateral is located and remove the same
and use in connection with such removal any and all services, supplies, aids and
other facilities of the Borrower or such Guarantor;

          (b)  instruct the obligor or obligors on any agreements, instrument or
other obligation constituting the Collateral to make any payment required by the
terms of such instrument or agreement directly to the Concentration Account or a
Qualified Account;

          (c)  withdraw all monies, securities and instruments in the
Concentration Account, any Qualified Account or the Letter of Credit Account for
application to the Obligations in accordance with Section 10.03;

          (d)  sell, assign or otherwise liquidate, or direct the Borrower
or any Guarantor to sell, assign or otherwise liquidate, any or all of the
Collateral or any part thereof in accordance with Section 10.02, and take
possession of the proceeds of any such sale, assignment or liquidation; and

          (e)  take possession of the Collateral or any part thereof, by
directing the Borrower and any Guarantor in writing to deliver the same to the
Agent at any place or places

                                       68

<PAGE>

designated by the Agent, in which event the Borrower and such Guarantor shall at
its own expense:

               (i)   forthwith cause the same to be moved to the place or places
so designated by the Agent and there delivered to the Agent,

               (ii)  store and keep any Collateral so delivered to the Agent at
such place or places pending further action by the Agent as provided in Section
10.02, and

               (iii) while the Collateral shall be so stored and kept, provide
such guards and maintenance services as shall be necessary to protect the same
and to preserve and maintain them in good condition;

it being  understood that the Borrower's and each  Guarantor's  obligation so to
deliver  the   Collateral  is  of  the  essence  of  this  Agreement  and  that,
accordingly,  upon  application  to the  Bankruptcy  Court,  the Agent  shall be
entitled to a decree  requiring  specific  performance  by the  Borrower or such
Guarantor of such obligation.

     SECTION 10.02. Remedies; Disposition of the Collateral. Upon the occurrence
and during the continuance of an Event of Default, and to the extent not
inconsistent with the Interim Order (or the Final Order, as applicable) or
Section 7, without application to or order of the Bankruptcy Court, any
Collateral repossessed by the Agent under or pursuant to Section 10.01 or the
Interim Order (or the Final Order, as applicable) or otherwise, and any other
Collateral whether or not so repossessed by the Agent, may be sold, assigned,
leased or otherwise disposed of under one or more contracts or as an entirety,
and without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Agent may, in compliance with any applicable
requirement of law, determine to be commercially reasonable. Any of the
Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Agent or after any overhaul or repair
which the Agent shall determine to be commercially reasonable. Any such
disposition which shall be a private sale or other private proceeding permitted
by applicable requirement of law shall be made upon not less than 10 days'
written notice to the Borrower specifying the time at which such disposition is
to be made and the intended sale price or other consideration therefor, and
shall be subject, for the 10 days after the giving of such notice, to the right
of the Borrower or any nominee of the Borrower to acquire the Collateral
involved at a price or for such other consideration at least equal to the
intended sale price or other consideration so specified. Any such disposition
which shall be a public sale permitted by applicable requirement of law shall be
made upon not less than 10 days' written notice to the Borrower specifying the
time and place of such sale and, in the absence of applicable requirement of
law, shall be by public auction (which may, at the Agent's option, be subject to
reserve), after publication of notice of such auction not less than 10 days
prior thereto in USA Today and The Wall Street Journal, National Edition.
Subject to Section 10.04, to the extent permitted by any such requirement of
law, the Agent on behalf of the Lenders may bid for and become the purchaser of
the Collateral or any item thereof, offered for sale in accordance with this
Section 10.02 without accountability to the Borrower, any Guarantor or the
Existing Lenders (except to the extent of surplus money received). If, under
mandatory requirement of law, the Agent shall be required to make disposition of
the Collateral within a period of time

                                       69

<PAGE>

which does not permit the giving of notice to the Borrower as hereinabove
specified, the Agent need give the Borrower only such notice of disposition as
shall be reasonably practicable.

     SECTION 10.03. Application of Proceeds. (a) Notwithstanding anything to the
contrary contained in this Agreement or any other Loan Document, (i) if the
Agent takes action under clause (i) or (ii) of Section 7.01 upon the occurrence
and during the continuance of an Event of Default, any payment by the Borrower
or any Guarantor on account of principal of and interest on the Loans and any
proceeds arising out of any realization (including after foreclosure) upon the
Collateral shall be applied as follows: first, to the payment of professional
fees pursuant to the Carve-Out and in accordance with this Agreement, second, to
the payment in full of all costs and out-of-pocket expenses (including without
limitation, reasonable attorneys' fees and disbursements) paid or incurred by
the Agent or any of the Lenders in connection with any such realization upon the
Collateral, third, to the payment in full of any Cash Management Obligations,
fourth, as a permanent reduction of the Commitments, pro rata in accordance with
each Lender's Commitment Percentage, to the payment in full of the Loans
(including any accrued and unpaid interest thereon, and any fees and other
Obligations in respect thereof), fifth, as a permanent reduction of the
Commitments, to the payment in full of Letter of Credit Outstandings
constituting unreimbursed drawings under any Letter of Credit and interest
thereon, sixth, as a permanent reduction of the Commitments, to the cash
collateralization of outstanding Letters of Credit by depositing cash into the
Letter of Credit Account such that the aggregate amount on deposit in the Letter
of Credit Account is equal to 105% of the face amount of all such Letters of
Credit in the manner set forth in Section 2.03(b), seventh, any surplus held by
the Agent after payment in full of all the Obligations and the termination of
the Total Commitment to be paid over to the Pre-Petition Agent under the
Existing Agreement for the payment in full of the Prepetition Obligations, and
eighth, any surplus remaining after payment in full of the Prepetition
Obligations shall be forthwith paid over to the Borrower or to whomsoever may be
lawfully entitled to receive such surplus, and (ii) any payments or
distributions of any kind or character, whether in cash, property or securities,
made by the Borrower or any Guarantor or otherwise in a manner inconsistent with
clause (i) of this Section 10.03(a) shall be held in trust and paid over or
delivered to the Agent so that the priorities and requirements set forth in such
clause (i) are satisfied.

          (b)  It is understood that the Borrower and the Guarantors shall
remain liable to the extent of any deficiency between the amount of the proceeds
of the Collateral and the amount of the Obligations.

     SECTION 10.04. WAIVER OF CLAIMS. EXCEPT AS OTHERWISE PROVIDED IN THIS
AGREEMENT, THE BORROWER AND THE GUARANTORS HEREBY WAIVE, TO THE EXTENT PERMITTED
BY APPLICABLE LAW:

          (A)  NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE AGENT'S TAKING
POSSESSION OR THE AGENT'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING,
WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT
REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH THE BORROWER OR ANY GUARANTOR WOULD
OTHERWISE HAVE UNDER ANY REQUIREMENT OF LAW AND THE BORROWER AND THE GUARANTORS
HEREBY FURTHER WAIVE, TO THE EXTENT PERMITTED BY LAW:

                                       70

<PAGE>

          (B)  all damages occasioned by such taking of possession except any
damages which are the direct result of the Agent's or any Lender's gross
negligence or willful misconduct;

          (C)  all other requirement to the time, place and terms of sale or
other requirements with respect to the enforcement of the Agent's rights
hereunder; and

          (D)  all rights of redemption, appraisement, valuation, stay,
extension or moratorium now or hereafter in force under any applicable law in
order to prevent or delay the enforcement of this Agreement or the absolute sale
of the Collateral or any portion thereof, and the Borrower and each Guarantor,
for itself and all who may claim under it, insofar as it or they now or
hereafter lawfully may, hereby waives the benefit of all such laws.

     SECTION 10.05. Remedies Cumulative. Each and every right, power and remedy
hereby specifically given to the Agent shall be in addition to every other
right, power and remedy specifically given under this Agreement, the Orders or
the other Loan Documents or now or hereafter existing at law or in equity, or by
statute and each and every right, power and remedy whether specifically herein
given or otherwise existing may be exercised from time to time or simultaneously
and as often and in such order as may be deemed expedient by the Agent. All such
rights, powers and remedies shall be cumulative and the exercise or the
beginning of exercise of one shall not be deemed a waiver of the right to
exercise of any other or others. No delay or omission of the Agent in the
exercise of any such right, power or remedy and no renewal or extension of any
of the Obligations shall impair any such right, power or remedy or shall be
construed to be a waiver of any Default or Event of Default or an acquiescence
therein. In the event that the Agent shall bring any suit to enforce any of its
rights hereunder and shall be entitled to judgment, then in such suit the Agent
may recover reasonable expenses, including attorneys' fees, and the amounts
thereof shall be included in such judgment.

     SECTION 10.06. Discontinuance of Proceedings. In case the Agent shall have
instituted any proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to the Agent, then and in every such case the Borrower, the Agent and
each holder of any of the Obligations shall be restored to their former
positions and rights hereunder with respect to the Collateral subject to the
Liens granted under this Agreement and the Orders, and all rights, remedies and
powers of the Agent and the Lenders shall continue as if no such proceeding had
been instituted.

     SECTION 11.02. Survival of Agreement, Representations and Warranties, etc.
     All warranties, representations and covenants made by the Borrower or any
Guarantor herein or in any certificate or other instrument delivered by it or on
its behalf in connection with this Agreement shall be considered to have been
relied upon by the Lenders and shall survive the making of the Loans herein
contemplated regardless of any investigation made by any Lender or on its behalf
and shall continue in full force and effect so long as any amount due or to
become due hereunder is outstanding and unpaid and so long as the Commitments

     SECTION 11.03. Successors and Assigns.

          (a)  This Agreement shall be binding upon and inure to the benefit of
the Borrower, the Agent and the Lenders and their respective successors and
assigns. Neither the Borrower nor any of the Guarantors may assign or transfer
any of their rights or obligations hereunder without the prior written consent
of all of the Lenders. Each Lender may sell participations to any Person in all
or part of any Loan, or all or part of its Commitment, in which event, without
limiting the foregoing, the provisions of Section 2.15 shall inure to the
benefit of each purchaser of a participation (provided that such participant
shall look solely to the seller of such participation for such benefits and the
Borrower's and the Guarantors' liability, if any, under Sections 2.15 and 2.18
shall not be increased as a result of the sale of any such participation) and
the pro rata treatment of payments, as described in Section 2.17, shall be
determined as if such Lender had not sold such participation. In the event any
Lender shall sell any participation, such Lender shall retain the sole right and
responsibility to enforce the obligations of the Borrower and each of the
Guarantors relating to the Loans, including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this Agreement
(provided that such Lender may grant its participant the right to consent to
such Lender's execution of amendments, modifications or waivers which (i) reduce
any Fees payable hereunder to the Lenders, (ii) reduce the amount of any
scheduled principal payment on any Loan or reduce the principal amount of any
Loan or the rate of interest payable hereunder or (iii) extend the maturity of
the Borrower's obligations hereunder). The sale of any such participation shall
not alter the rights and obligations of the Lender selling such participation
hereunder with respect to the Borrower.

          (b)  Each Lender may assign to one or more Lenders or Eligible
Assignees all or a portion of its interests, rights and obligations under this
Agreement (including, without

                                       72

<PAGE>

limitation, all or a portion of its Commitment and the same portion of the
related Loans at the time owing to it), provided, however, that (i) other than
in the case of an assignment to a Person at least 50% owned by the assignor
Lender, or to a Lender Affiliate of such assignor Lender, or by a common parent
of both, or to another Lender, the Agent and the Fronting Bank must give their
respective prior written consent to such assignment, which consent will not be
unreasonably withheld, (ii) the aggregate amount of the Commitment and/or Loans
of the assigning Lender subject to each such assignment (determined as of the
date the Assignment and Acceptance with respect to such assignment is delivered
to the Agent) shall, unless otherwise agreed to in writing by the Borrower and
the Agent, in no event be less than $1,000,000 or the remaining portion of such
Lender's Commitment and/or Loans, if less, (iii) the parties to each such
assignment shall execute and deliver to the Agent, for its acceptance and
recording in the Register (as defined below), an Assignment and Acceptance with
blanks appropriately completed, together with a processing and recordation fee
of $3,500 (for which the Borrower shall have no liability), (iv) such assigning
Lender shall deliver to the Agent or the Borrower any Note (if the assigning
Lender's Loans are evidenced by a promissory note) subject to assignment and (v)
the assignee shall execute and deliver to the Borrower and the Agent the
appropriate forms and documentation described in Section 2.18 to satisfy the
requirements of Section 2.18. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment and
Acceptance, which effective date shall be within ten Business Days after the
execution thereof (unless otherwise agreed to in writing by the Agent), (A) the
assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
and (B) the Lender thereunder shall, to the extent provided in such Assignment
and Acceptance, be released from its obligations under this Agreement (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of an assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto).

          (c)  By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than the
representation and warranty that it is the legal and beneficial owner of the
interest being assigned thereby free and clear of any adverse claim, such Lender
assignor makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Agreement or any of the other Loan Documents or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any of the other Loan Documents; (ii) such Lender assignor
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of the Borrower or any Guarantor or the performance
or observance by the Borrower or any Guarantor of any of its obligations under
this Agreement or any of the other Loan Documents or any other instrument or
document furnished pursuant hereto; (iii) such assignee confirms that it has
received a copy of this Agreement and the other Loan Documents, together with
copies of the financial statements referred to in Section 3.04 and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (iv) such
assignee will, independently and without reliance upon the Agent, such Lender
assignor or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to

                                       73

<PAGE>

exercise such powers under this Agreement as are delegated to the Agent by the
terms thereto, together with such powers as are reasonably incidental hereof;
and (vi) such assignee agrees that it will perform in accordance with their
terms all obligations that by the terms of this Agreement are required to be
performed by it as a Lender.

          (d)  The Agent, as agent of the Borrower, shall maintain at its office
a copy of each Assignment and Acceptance delivered to it and a register for the
recordation of (i) the names and addresses of the Lenders and the Commitments
of, and principal amount of the Loans and interest amounts owing to, and paid
to, each Lender from time to time, (ii) the amount of any sum received by the
Agent hereunder for the account of the Lenders and each Lender's share thereof,
(iii) the name and address of the Fronting Bank, (iv) the Letter of Credit
Outstandings (including, specifying all amounts theretofore drawn under Letters
of Credit and not then reimbursed) with respect to the Fronting Bank, (v) all
participations in Letters of Credit, (vi) the amount of any principal or
interest due and payable (or to become due and payable) and paid with respect to
drawn Letters of Credit and participations in drawn Letters of Credit, including
amounts described in Section 2.03 owing and paid to Fronting Bank and Lenders
from time to time with respect to such drawn Letters of Credit (the "Register").
The entries in the Register shall be conclusive, in the absence of manifest
error, and the Borrower, the Guarantors, the Agent and the Lenders shall treat

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and the assignee thereunder together with the fee payable in
respect thereto, the Agent shall, if such Assignment and Acceptance has been
completed with blanks appropriately filled and consented to by the Agent and the
Fronting Bank (to the extent such consent is required hereunder), (i) accept
such Assignment and Acceptance, (ii) record the information contained therein in
the Register and (iii) give prompt written notice thereof to the Borrower
(together with a copy thereof). No assignment shall be effective for purposes of
this Agreement unless it has been recorded in the Register as provided in this
paragraph.

          (f)  Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
11.03, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower or any of the Guarantors
furnished to such Lender by or on behalf of the Borrower or any of the

participant or proposed assignee or participant shall agree in writing to be
bound by the provisions of Section 11.04.

reimbursement obligation with respect to a Letter of Credit, (i) such Fronting
Bank shall give notice of such transfer to the

<PAGE>

Agent for notation in the Register, (ii) each such assignment shall be notated
in the Register, and (iii) no such transfer will be effective for purposes of
this Agreement unless it has been recorded in the Register.

     SECTION 11.04. Confidentiality. Each Lender agrees to keep any information
delivered or made available by the Borrower or any of the Guarantors to it
confidential from anyone other than persons employed or retained by such Lender
who are or are expected to become engaged in evaluating, approving, structuring
or administering the Loans; provided that nothing herein shall prevent any
Lender from disclosing such information (i) to any of its Affiliates or to any
other Lender, provided such Affiliate agrees to keep such information
confidential to the same extent required by the Lenders hereunder, (ii) upon the
order of any court or administrative agency, (iii) upon the request or demand of
any regulatory agency or authority, (iv) which has been publicly disclosed other
than as a result of a disclosure by the Agent or any Lender or any Affiliate
thereof which is not permitted by this Agreement, (v) in connection with any
litigation to which the Agent, any Lender, or their respective Affiliates may be
a party to the extent reasonably required, (vi) to the extent reasonably
required in connection with the exercise of any remedy hereunder, (vii) to such
Lender's legal counsel and independent auditors, and (viii) to any actual or
proposed participant or assignee of all or part of its rights hereunder subject
to the proviso in Section 11.03(f). Each Lender shall use reasonable efforts to
notify the Borrower of any required disclosure under clause (ii), (iii) or (v)
of this Section. Notwithstanding anything to the contrary set forth herein or in
any other agreement to which the parties hereto are parties or by which they are
bound, the obligations of confidentiality contained herein and therein, as they
relate to the transactions contemplated by this Agreement, shall not apply to
the tax structure or tax treatment of such transactions, and each party hereto
(and any employee, representative, or agent of any party hereto) may disclose to
any and all persons, without limitation of any kind, the tax structure and tax
treatment of such transactions and all materials of any kind (including opinions
or other tax analysis) that are provided to such party relating to such tax
treatment and tax structure; provided, however, that such disclosure shall not
include the name (or other identifying information not relevant to the tax
structure or tax treatment) of any person and shall not include information for
which nondisclosure is reasonably necessary in order to comply with applicable
securities laws.

     SECTION 11.05. Expenses. Whether or not the transactions hereby
contemplated shall be consummated, the Borrower and the Guarantors agree to pay
all reasonable and documented out-of-pocket expenses incurred by the Agent

Thacher & Bartlett, special counsel for the Agent, any other counsel that the
Agent shall retain and any internal or third-party appraisers, consultants,
financial advisors and auditors advising the Agent and J.P. Morgan Securities
Inc.) in connection with the preparation, execution, delivery and administration
of this Agreement and the other Loan Documents, the making of the Loans and the
issuance of the Letters of Credit, the perfection of the Liens contemplated

for the Initial Lenders) in connection with the preparation, execution and

                                       75

<PAGE>

delivery of this Agreement and the other Loan Documents, the making of the Loans
and the issuance of the Letters of Credit, and, following the occurrence of an
Event of Default, all reasonable out-of-pocket expenses incurred by the Lenders
and the Agent in the enforcement or protection of the rights of any one or more
of the Lenders or the Agent in connection with this Agreement or the other Loan
Documents, including but not limited to the reasonable fees and disbursements of
any counsel for the Lenders or the Agent. Such payments shall be made on the
date of the Interim Order and thereafter on demand upon delivery of a statement
setting forth such costs and expenses in reasonable detail. Whether or not the
transactions hereby contemplated shall be consummated, the Borrower and the
Guarantors agree to reimburse the Agent, the Initial Lenders and J.P. Morgan
Securities Inc. for the expenses set forth in the Commitment Letter and the
reimbursement provisions thereof are hereby incorporated herein by reference.
The obligations of the Borrower and the Guarantors under this Section shall
survive the termination of this Agreement and/or the payment of the Loans.

     SECTION 11.06. Indemnity. The Borrower and each of the Guarantors agree to
indemnify and hold harmless the Agent, J.P. Morgan Securities Inc. and the
Lenders and their directors, officers, employees, agents and Affiliates (each an
"Indemnified Party") from and against any and all expenses, losses, claims,
damages and liabilities incurred by such Indemnified Party arising out of claims
made by any Person in any way relating to the transactions contemplated hereby,
but excluding therefrom all expenses, losses, claims, damages, and liabilities
to the extent that they are determined by the final judgment of a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of such Indemnified Party. The obligations of the Borrower and the
Guarantors under this Section shall survive the termination of this Agreement
and/or the payment of the Loans.

     SECTION 11.07. CHOICE OF LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
SHALL IN ALL RESPECTS BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS
OF THE STATE OF NEW YORK AND (TO THE EXTENT APPLICABLE) THE BANKRUPTCY CODE.

     SECTION 11.08. No Waiver. No failure on the part of the Agent or any of the
Lenders to exercise, and no delay in exercising, any right, power or remedy
hereunder or any of the other Loan Documents shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or remedy
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. All remedies hereunder are cumulative and are not
exclusive of any other remedies provided by law.

     SECTION 11.09. Extension of Maturity. Should any payment of principal of or
interest or any other amount due hereunder become due and payable on a day other
than a Business Day, the due date thereof shall be extended to the next
succeeding Business Day and, in the case of principal, interest shall be payable
thereon at the rate herein specified during such extension.

     SECTION 11.10. Amendments, etc.

          (a)  No modification, amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by the
Borrower or any Guarantor

                                       76

<PAGE>

therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Required Lenders, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given;
provided, however, that no such modification or amendment shall without the
written consent of the Lender affected thereby (x) increase the Commitment of a
Lender (it being understood that a waiver of an Event of Default shall not
constitute an increase in the Commitment of a Lender), or (y) reduce the
principal amount of any Loan or the rate of interest payable thereon, or extend
any date for the payment of interest hereunder or reduce any Fees payable
hereunder or extend the final maturity of the Borrower's obligations hereunder;
and, provided, further, that no such modification or amendment shall without the
written consent of all of the Lenders (i) amend or modify any provision of this
Agreement which provides for the unanimous consent or approval of the Lenders,
(ii) amend this Section 11.10 or the definition of Required Lenders, (iii) amend
or modify the Superpriority Claim status of the Lenders contemplated by Section
2.23 or (iv) release or subordinate all or any substantial portion of the Liens
granted to the Agent hereunder, under the Orders or under any other Loan
Document, or release all or substantially all of the Guarantors. No such
amendment or modification may adversely affect the rights and obligations of the
Agent or any Fronting Bank hereunder or any Lender in respect of Cash Management
Obligations owing to such Lender without its prior written consent. No notice to
or demand on the Borrower or any Guarantor shall entitle the Borrower or any
Guarantor to any other or further notice or demand in the same, similar or other
circumstances. Each assignee under Section 11.03(b) shall be bound by any
amendment, modification, waiver, or consent authorized as provided herein, and
any consent by a Lender shall bind any Person subsequently acquiring an interest
on the Loans held by such Lender. No amendment to this Agreement shall be
effective against the Borrower or any Guarantor unless signed by the Borrower or
such Guarantor, as the case may be.

          (b)  Notwithstanding anything to the contrary contained in Section
11.10(a), in the event that the Borrower requests that this Agreement be
modified or amended in a manner which would require the unanimous consent of all
of the Lenders and such modification or amendment is agreed to by the
Super-majority Lenders (as hereinafter defined), then with the consent of the
Borrower and the Super-majority Lenders, the Borrower and the Super-majority
Lenders shall be permitted to amend the Agreement without the consent of the
Lender or Lenders which did not agree to the modification or amendment requested
by the Borrower (such Lender or Lenders, collectively the "Minority Lenders") to
provide for (w) the termination of the Commitment of each of the Minority
Lenders, (x) the addition to this Agreement of one or more other financial
institutions (each of which shall be an Eligible Assignee), or an increase in
the Commitment of one or more of the Super-majority Lenders, so that the Total
Commitment after giving effect to such amendment shall be in the same amount as
the Total Commitment immediately before giving effect to such amendment, (y) if
any Loans are outstanding at the time of such amendment, the making of such
additional Loans by such new financial institutions or Super-majority Lender or
Lenders, as the case may be, as may be necessary to repay in full the
outstanding Loans of the Minority Lenders immediately before giving effect to
such amendment and (z) such other modifications to this Agreement as may be
appropriate. As used herein, the term "Super-majority Lenders" shall mean, at
any time, Lenders holding Loans representing at least 66-2/3% of the aggregate
principal amount of the Loans outstanding, or if no Loans are outstanding,
Lenders having Commitments representing at least 66-2/3% of the Total
Commitment.

     SECTION 11.11. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     SECTION 11.12. Headings. Section headings used herein are for convenience
only and are not to affect the construction of or be taken into consideration in
interpreting this Agreement.

     SECTION 11.13. Execution in Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall constitute an original, but all
of which taken together shall constitute one and the same instrument.

     SECTION 11.14. Prior Agreements. This Agreement represents the entire
agreement of the parties with regard to the subject matter hereof and the terms
of any letters and other documentation entered into between the Borrower or a
Guarantor and any Lender or the Agent prior to the execution of this Agreement
which relate to Loans to be made hereunder shall be replaced by the terms of
this Agreement (except as otherwise expressly provided herein with respect to
the Commitment Letter and the fee letter referred to therein, including without
limitation the Borrower's agreement to actively assist the Agent in the
syndication of the transactions contemplated hereby referred to in Section
11.03(g) and including also the provisions of Section 2.19).

     SECTION 11.15. Further Assurances. Whenever and so often as reasonably
requested by the Agent, the Borrower and the Guarantors will promptly execute
and deliver or cause to be executed and delivered all such other and further
instruments, documents or assurances, and promptly do or cause to be done all
such other and further things as may be necessary and reasonably required in
order to further and more fully vest in the Agent all rights, interests, powers,
benefits, privileges and advantages conferred or intended to be conferred by
this Agreement and the other Loan Documents.

     SECTION 11.16. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE GUARANTORS,
THE AGENT AND EACH LENDER HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY OF
THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY.
